                 QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE
                         SPECIAL MEETING OF SHAREHOLDERS

Q:   WHAT IS THE PROPOSED TRANSACTION?

A: Pursuant to the Amended and Restated Agreement and Plan of Merger (the
"Merger Agreement") (attached as Appendix A to this proxy statement-prospectus),
Farmers State Bank of Breckenridge ("Farmers") will acquire Farwell through a
merger transaction in which Farwell will merge with and into Farmers. At the
effective time of the merger, Farmers will change its name to FSB Bank ("FSB").
FSB will continue to be a wholly-owned subsidiary of IBT.

Q:   WHAT ARE THE TAX CONSEQUENCES OF THE MERGER TO ME?

A: Generally speaking, because you will receive a combination of IBT common
stock and cash, you should recognize a capital gain, but not loss, on the
exchange to the extent of the lesser of cash received or gain realized in the
exchange. This tax treatment may not apply to all Farwell shareholders. Farwell
shareholders should consult their own tax advisors for a full understanding of
the tax consequences of the merger. Farwell recommends that Farwell shareholders
carefully read the complete explanation of the "Material Federal Income Tax
Consequences" of the merger beginning on page _____.

Q:   WHAT DO I NEED TO DO NOW?

A: After you have carefully read this document, indicate on your proxy card how
you want your shares to be voted. Then sign and mail your proxy card in the
enclosed prepaid return envelope as soon as possible. This will enable your
shares to be represented and voted at the special meeting.

Q:   WHY IS MY VOTE IMPORTANT?

A: The Merger Agreement must be adopted by 66 2/3% of the shares of Farwell
issued and outstanding as of the record date for the special meeting
(_______________, 2006). A failure to vote will have the same effect as a vote
against the Merger Agreement.

Q:   IF MY BROKER HOLDS MY SHARES IN "STREET NAME" WILL MY BROKER AUTOMATICALLY
     VOTE MY SHARES FOR ME?

A: No. Your broker will not be able to vote your shares without instructions
from you. You should instruct your broker to vote your shares, following the
directions your broker provides.

Q:   WHAT IF I FAIL TO INSTRUCT MY BROKER TO VOTE MY SHARES?

A: If you fail to instruct your broker to vote your shares, the broker will
submit an unvoted proxy (a broker non-vote) as to your shares. Broker non-votes
will count toward a quorum at the special meeting. However, broker non-votes
will not count as a vote with respect to the Merger Agreement, and therefore
will have the same effect as a vote against the Merger Agreement.

Q:   CAN I ATTEND THE SPECIAL MEETING AND VOTE MY SHARES IN PERSON?

A: Yes. All shareholders are invited to attend the special meeting. Shareholders
of record can vote in person at the special meeting by executing a proxy card.
If a broker holds your shares in street name, then you are not the shareholder
of record and you must ask your broker how you can vote your shares at the
special meeting.

Q:   CAN I CHANGE MY VOTE?

A: Yes. If you have not voted through your broker, you can change your vote
after you have sent in your proxy card by:

-    providing written notice to the Secretary of Farwell;

-    submitting a new proxy card. Any earlier proxies will be revoked
     automatically; or

-    attending the special meeting and voting in person. Any earlier proxy will
     be revoked. However, simply attending the special meeting without voting
     will not revoke your proxy.


                                        1



If you have instructed a broker to vote your shares, you must follow your
broker's directions to change your vote.

Q:   SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A: PLEASE DO NOT send your stock certificates with your proxy card. You will be
sent a letter of transmittal to complete and return with your Farwell common
stock certificate after the completion of the merger.

Q:   WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A: Farmers and Farwell currently expect to complete the merger in the third
quarter of 2006, assuming all of the conditions to completion of the merger have
been satisfied.

Q:   WHAT WILL SHAREHOLDERS OF FARWELL RECEIVE IN THE MERGER?

A: If the Merger Agreement is approved and the merger is subsequently completed,
each outstanding share of Farwell common stock (other than any dissenting
shares) will be converted into the right to receive 3.0382 shares of IBT common
stock and $29.00 in cash subject to adjustment under certain circumstances. Cash
will be paid in lieu of any fractional share of IBT common stock.

Q:   WHOM SHOULD I CALL WITH QUESTIONS?

A: You should direct any questions regarding the special meeting of shareholders
or the merger to Thomas E. Kedrowski, President and Chief Executive Officer of
Farwell at (989) 588-9945.


                                        2

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER (PAGE
_____)

As a result of receiving a combination of IBT common stock and cash in exchange
for shares of Farwell common stock, you will likely recognize gain, but not
loss, equal to the lesser of (1) the amount of cash received or (2) the amount
of gain realized in the transaction.


                                        3



Generally, the actual U.S. federal income tax consequences to you will depend on
whether your shares of Farwell common stock were purchased at different times
and at different prices and the character of the gain, if any, as either capital
gain or ordinary income.

You should read "Material United States Federal Income Tax Consequences of the
Merger" starting on page _____ for a more complete discussion of the federal
income tax consequences of the merger. Tax matters can be complicated and the
tax consequences of the merger to you will depend on your particular tax
situation. You should consult your own tax advisor to fully understand the tax
consequences of the merger to you.

YOUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS SHAREHOLDER APPROVAL OF THE
MERGER (PAGE _____)

The Board of Directors of Farwell believes that the merger presents an
opportunity to join a financial institution that will have greater financial
strength and earning power than Farwell would have on its own, as well as the
added scale necessary to undertake and solidify leadership positions.

As a result, the Board of Directors of Farwell unanimously approved the Merger
Agreement. The Board of Directors of Farwell believes that the merger and the
Merger Agreement are fair to and in the best interests of Farwell and its
shareholders and unanimously recommends that you vote "FOR" adoption of the
Merger Agreement.

OPINIONS OF FINANCIAL ADVISORS (PAGE _____ AND APPENDIX B AND C)

In connection with the merger, the Board of Directors of Farwell, Farmers and
IBT received the written opinion of Austin Associates, LLC, that the terms of
the merger are fair to IBT's and Farwell's shareholders from a financial point
of view. In addition, Donnelly Penman & Partners has given its written opinion
to Farwell's Board of Directors that the consideration to be received in the
merger by Farwell shareholders is fair from a financial point of view. The full
texts of the opinion of Austin Associates, LLC, dated _______________, 2006 and
the opinion of Donnelly Penman & Partners dated _______________, 2006 are
included in this document as Appendix B and C, respectively. Farwell encourages
you to read these opinions carefully in their entirety for a description of the
procedures followed, assumptions made, matters considered and limitations of the
review undertaken by Austin Associates, LLC and Donnelly Penman & Partners. The
opinions do not constitute a recommendation to you or any other shareholder as
to how to vote with respect to the merger, or any other matter relating to the
proposed transaction. Austin Associates, LLC and Donnelly Penman & Partners will
each receive a fee for rendering their respective fairness opinions in
connection with the merger.

SPECIAL MEETING OF SHAREHOLDERS OF FARWELL (PAGE _____)

Farwell will hold a special meeting of its shareholders on _______________, 2006
at ___:00 __.m., Michigan time, at ______________________________, Michigan. At
the special meeting of shareholders, you will be asked to vote to adopt the
Merger Agreement.

You may vote at the special meeting of shareholders if you owned shares of
Farwell common stock at the close of business on the record date,
_______________, 2006. On that date, there were __________ shares of Farwell
common stock outstanding and entitled to vote at the special meeting of
shareholders. You may cast one vote for each share of Farwell common stock you
owned on the record date.

Even if you expect to attend the special meeting of shareholders, Farwell
recommends that you promptly complete and return your proxy card in the enclosed
return envelope.

SHAREHOLDER VOTE REQUIRED (PAGE _____)

Adoption of the Merger Agreement requires the affirmative vote of the holders of
66 2/3% of the shares of Farwell common stock issued and outstanding on the
record date. A failure to vote or an abstention will have the same effect as a
vote against the merger. As of the record date, directors and executive officers
of Farwell beneficially owned 75,485 shares of Farwell common stock entitled to
vote at the special meeting of shareholders. This represents approximately 28.8%
of the total votes entitled to be cast at the special meeting of shareholders.
These individuals have indicated that they will vote "FOR" adoption of the
Merger Agreement.

DISSENTERS' RIGHTS OF APPRAISAL (PAGE _____ AND APPENDIX D)

Under Section 3706(2)(b) of the Michigan Banking Code of 1999, holders of
Farwell common stock have the right to obtain an appraisal of the value of their
shares of Farwell common stock in connection with the merger. To perfect
appraisal rights, a Farwell shareholder must not vote for the adoption of the
Merger Agreement and must strictly comply with all of the procedures required
under Section 3706(2)(b) of the Michigan Banking Code of 1999.


                                        4



We have included a copy of Section 3706(2)(b) of the Michigan Banking Code of
1999 relating to dissenters' rights as Appendix D to this document.

INTERESTS OF FARWELL'S DIRECTORS AND OFFICERS IN THE MERGER (PAGE _____)

In considering the recommendation of the Board of Directors of Farwell to
approve the merger, you should be aware that certain executive officers and
directors of Farwell have employment and other compensation agreements or plans
and continuing liability insurance and indemnification protections that give
them interests in the merger that are somewhat different from, or in addition
to, the interests of Farwell shareholders.

REGULATORY APPROVALS REQUIRED FOR THE MERGER (PAGE _____)

We cannot complete the merger without the prior approval or non-objection of the
Federal Deposit Insurance Corporation and the Michigan Office of Financial and
Insurance Services. Farmers is in the process of seeking these approvals and
non-objections. While we do not know of any reason why Farmers would not be able
to obtain the necessary approvals in a timely manner, we cannot assure you that
these approvals and non-objections will occur or what the timing may be or that
these approvals and non-objections will not be subject to one or more conditions
that affect the advisability of the merger.

CONDITIONS TO THE MERGER (PAGE _____)

Completion of the merger depends on a number of conditions being satisfied or
waived, including but not limited to the following:

-    the Farwell shareholders must have adopted the Merger Agreement;

-    the Federal Deposit Insurance Corporation and the Michigan Office of
     Financial and Insurance Services must have approved or not objected to the
     merger, as appropriate, and all statutory waiting periods must have
     expired;

-    no stop order suspending the effectiveness of IBT's registration statement
     of which this document is a part shall have been issued and no proceedings
     for that purpose shall have been initiated or threatened by the Securities
     and Exchange Commission; and

-    the holders of no more than 10% of Farwell's shares of common stock have
     indicated their intention to seek dissenter's rights of appraisal.

Other conditions to the completion of the merger are described beginning on page
_____. We cannot be certain when, or if, the conditions to the merger will be
satisfied or waived or whether or not the merger will be completed.

NO SOLICITATION (PAGE _____)

Farwell has agreed, subject to certain limited exceptions, not to initiate
discussions with another party regarding a business combination with such other
party while the merger with Farmers is pending.

TERMINATION OF THE MERGER AGREEMENT (PAGE _____)

Farmers and Farwell may mutually agree at any time to terminate the Merger
Agreement without completing the merger, even if Farwell shareholders have
approved it. Also, either party may decide, without the consent of the other
party, to terminate the Merger Agreement under specified circumstances, if the
required regulatory approvals are not received or if the other party breaches
its agreements.

DIFFERENCES IN RIGHTS OF SHAREHOLDERS (PAGE _____)

The rights of Farwell shareholders after the merger who continue as IBT
shareholders will be governed by Michigan corporate law and the articles of
incorporation and bylaws of IBT rather than the articles of incorporation and
bylaws of Farwell, which are governed by Michigan banking law.

                                 CAPITAL RATIOS

Under the "risk-based" capital guidelines presently in effect for banks and bank
holding companies, minimum capital levels are based on the perceived risk in the
various asset categories. Certain off-balance-sheet instruments, such as loan
commitments and letters of credit, require capital allocations. Bank holding
companies such as IBT and banks such as Farwell are required to maintain minimum
risk-based capital ratios. IBT's and Farwell's ratios are above the regulatory
minimum guidelines, Farwell met the regulatory criteria to be categorized as a
"well-capitalized" institution as of December 31, 2005. The "well-capitalized"
classification may permit banks to minimize the cost of FDIC insurance
assessments by being charged a lesser rate than those that do not meet this
definition. Designation as a "well-capitalized" institution does not constitute
a recommendation by federal bank regulators. The following table shows capital
ratios and requirements as of March 31, 2006



                                                                      RISK-BASED CAPITAL

                     COMPARATIVE PER SHARE DATA (UNAUDITED)

The following table shows pro forma information about earnings per share,
dividends per share, and book value per share.

IBT anticipates that the combined company will derive financial benefits from
the merger that include reduced operating expenses and the opportunity to earn
more revenue. The pro forma information, while helpful in illustrating the
financial characteristics of the combined entities under one set of assumptions,
does not reflect these benefits and, accordingly, does not attempt to credit or
suggest future results. The pro forma information also does not necessarily
reflect what the historical results of the combined entities would have been had
the companies actually been combined during these periods.

The pro forma information in the following table is based on, and should be read
together with, the historical financial information that is presented in this
document and in IBT's prior filings with the SEC and with the condensed combined
pro forma financial statements presented elsewhere in this document. See "Where

(1)  The Pro Forma Combined earnings per share amounts were calculated by
     totaling the historical earnings of IBT and Farwell and dividing the
     resulting amount by the average pro forma shares of IBT and Farwell giving
     effect to the merger as if it had occurred as of the beginning of the
     periods presented. The average pro forma shares of IBT and Farwell reflect
     historical basic and diluted shares, plus historical basic and diluted
     average shares of Farwell, as adjusted based on an assumed exchange ratio
     of 3.0382 shares of IBT common stock, plus the payment of $29.00 in cash,
     for each share of Farwell common stock. The aggregate merger consideration
     to be paid by Farmers is subject to certain adjustments pursuant to the
     Merger Agreement. The pro forma earnings amounts do not take into
     consideration any operating efficiencies that may be realized as a result
     of the merger.

(2)  Pro Forma Combined cash dividends paid represents IBT's historical amount
     only.

(3)  The Pro Forma Combined tangible book value data gives effect to the merger
     as if it had occurred on March 31, 2006 and December 31, 2005.

(4)  The Equivalent Pro Forma Per Share of Farwell amounts were calculated by
     multiplying the Pro Forma Combined amounts by the assumed exchange ratio of
     3.0382 shares of IBT common stock for each share of Farwell common stock.
     These amounts do not take into consideration any operating efficiencies
     that may be realized as a result of the merger. This data is presented for
     comparative purposes only.

                                  RISK FACTORS

In addition to the other information contained in or incorporated by reference
into this proxy statement-prospectus, including the matters addressed under the
caption "Forward-Looking Statements," on page _____ you should carefully
consider the following risk factors in deciding whether to vote for adoption of
the Merger Agreement.

RISKS RELATED TO THE MERGER

IBT MAY FAIL TO REALIZE THE ANTICIPATED BENEFITS OF THE MERGER.

The success of the merger will depend on, among other things, IBT's ability to
realize anticipated cost savings, to conduct the business of Farwell in a manner
that does not materially disrupt the existing customer relationships of Farwell
nor result in decreased revenues resulting from any loss of customers, and
permits growth opportunities to occur. Farwell represents a new market area for
IBT. If IBT is not able to successfully achieve these objectives, the
anticipated benefits of the merger may not be fully realized, realized at all or
may take longer to realize than expected.

Farmers and Farwell have operated and, until the completion of the merger, will
continue to operate, independently. It is possible that the integration process
could result in the loss of key employees, the disruption of Farwell's ongoing
business or inconsistencies in standards, controls, procedures and policies that
adversely affect the ability of IBT to maintain relationships with customers and
employees or to achieve the anticipated benefits of the merger.

FARWELL DIRECTORS AND OFFICERS HAVE INTERESTS IN THE MERGER THAT DIFFER FROM
THOSE OF A SHAREHOLDER.

Farwell's directors and officers have various interests in the merger that
differ from, or are in addition to, the interests of Farwell shareholders. These
interests include:

-    the agreement by Farmers to employ Mr. Kedrowski pursuant to a two-year
     written employment agreement.

-    following completion of the merger, the Farwell officers will continue to
     serve with Farmers and the Farwell directors will serve on a regional
     advisory board for the Farwell division of Farmers and shall receive the
     same board member compensation as provided by Farwell prior to the merger.

-    upon completion of the merger, Michael McGuire shall join the reconstituted
     Farmers' Board of Directors.

-    the agreement by Farmers to employ all current Farwell employees pursuant
     to a five-year written employment agreement.

-    the agreement by Farmers to provide liability insurance and indemnification
     protection to Farwell directors and officers.

RISKS ABOUT IBT

IBT'S CURRENT CONCENTRATION OF LOANS IN ITS PRIMARY MARKET AREA MAY INCREASE ITS
RISK.

IBT's success depends primarily on the general economic conditions in
Mid-Michigan. Unlike larger banks that are more geographically diversified, IBT
provides banking and financial services to customers primarily in Mid-Michigan.
The local economic conditions in the Mid-Michigan area have a significant impact
on its loans, the ability of the borrowers to repay these loans and the value of
the collateral securing these loans. A significant decline in general economic
conditions caused by inflation, recession, unemployment or other factors beyond
IBT's control would impact these local economic conditions and could negatively
affect the financial results of its banking operations.

IBT targets its business lending and marketing strategy for loans to serve
primarily the banking and financial services needs of small to medium size
businesses. These small to medium size businesses generally have fewer financial
resources in terms of capital or borrowing capacity than larger entities. If
general economic conditions negatively impact these businesses, IBT's results of
operations and financial condition may be adversely affected.


                                       10



CHANGES IN INTEREST RATES COULD ADVERSELY AFFECT IBT'S RESULTS OF OPERATIONS AND
FINANCIAL CONDITION.

IBT's results of operations and financial condition are significantly affected
by changes in interest rates. IBT's results of operations depend substantially
on its net interest income, which is the difference between the interest income
earned on its interest-earning assets and the interest expense paid on its
interest-bearing liabilities. At December 31, 2005, IBT's interest rate risk
profile indicated that net interest income would increase in a rising long term
interest rate environment, but would decrease in a declining long term interest
rate environment.

Changes in interest rates also affect the value of IBT's interest-earning
assets, and in particular IBT's securities portfolio. Generally, the value of
securities fluctuates inversely with changes in interest rates. At December 31,
2005, IBT's available for sale securities totaled $183 million. Decreases in the
fair value of securities available for sale could have an adverse effect on
shareholders' equity or earnings.

IBT also is subject to reinvestment risk associated with changes in interest
rates. Changes in interest rates may affect the average life of loans and
mortgage-related securities. Decreases in interest rates can result in increased
prepayments of loans and mortgage-related securities, as borrowers refinance to
reduce borrowing costs. Under these circumstances, IBT is subject to
reinvestment risk to the extent that it is unable to reinvest the cash received
from such prepayments at rates that are comparable to the rates on existing
loans and securities. Additionally, increases in interest rates may decrease
loan demand and make it more difficult for borrowers to repay adjustable rate
loans.

STRONG COMPETITION WITHIN IBT'S MARKET AREA MAY LIMIT ITS GROWTH AND
PROFITABILITY.

Competition in the banking and financial services industry is intense. In IBT's
market area, IBT competes with commercial banks, savings institutions, mortgage
brokerage firms, credit unions, finance companies, mutual funds, insurance
companies, and brokerage and investment banking firms operating locally and
elsewhere. Many of these competitors (whether regional or national institutions)
have substantially greater resources and lending limits than IBT does and may
offer certain services that IBT does not or cannot provide. IBT's profitability
depends upon its continued ability to successfully compete in its market area.

IBT OPERATES IN A HIGHLY REGULATED ENVIRONMENT AND MAY BE ADVERSELY AFFECTED BY
CHANGES IN LAWS AND REGULATIONS.

IBT is subject to regulation, supervision and examination by the Board of
Governors of the Federal Reserve. Isabella Bank and Trust and Farmers State Bank
of Breckenridge are subject to regulation by the Office of Financial and
Insurance Services of the State of Michigan and by the Federal Deposit Insurance
Corporation, as insurer of their deposits. Such regulation and supervision
govern the activities in which a bank and its holding company may engage and are
intended primarily for the protection of the deposit insurance funds and
depositors. These regulatory authorities have extensive discretion in connection
with their supervisory and enforcement activities, including the imposition of
restrictions on the operation of a bank, the classification of assets by a bank
and the adequacy of a bank's allowance for loan losses. Any change in such
regulation and oversight, whether in the form of regulatory policy, regulations,
or legislation, could have a material impact on IBT and its operations.

IBT's operations are also subject to extensive regulation by other federal,
state and local governmental authorities and are subject to various laws and
judicial and administrative decisions imposing requirements and restrictions on
part or all of its operations. IBT believes that it is in substantial compliance
in all material respects with applicable federal, state and local laws, rules
and regulations. Because its business is highly regulated, the laws, rules and
regulations applicable to IBT are subject to regular modification and change.
There are currently proposed various laws, rules and regulations that, if
adopted, would impact its operations, including, among other things, matters
pertaining to corporate governance and SEC rules pertaining to public reporting
disclosures. There can be no assurance that these proposed laws, rules and
regulations, or any other laws, rules or regulations, will not be adopted in the
future, which could make compliance more difficult or expensive or otherwise
adversely affect its business, financial condition or prospects.

                           THE FARWELL SPECIAL MEETING

Farwell is mailing this proxy statement-prospectus to you as a Farwell
shareholder on or about _______________, 2006. With this document, Farwell is
sending you a notice of the Farwell special meeting of shareholders and a form
of proxy that is solicited by Farwell's Board of Directors. The special meeting
will be held on _______________, 2006 at ___:00 _.m., local time, at
________________________________________, Michigan.

MATTERS TO BE CONSIDERED

The sole purpose of the special meeting of shareholders is to vote on the
adoption of the Merger Agreement by which Farwell will merge with and into
Farmers.


                                       11



You may also be asked to vote upon a proposal to adjourn or postpone the special
meeting of shareholders. Farwell could use any adjournment or postponement for
the purpose, among others, of allowing additional time to solicit proxies.

PROXY CARD, REVOCATION OF PROXY

You should complete and return the proxy card accompanying this document to
ensure that your vote is counted at the special meeting of shareholders,
regardless of whether you plan to attend. You can revoke your proxy at any time
before the vote is taken at the special meeting by:

-    submitting written notice of revocation to the Secretary of Farwell;

-    submitting a properly executed proxy bearing a later date before the
     special meeting of shareholders; or

-    voting in person at the special meeting of shareholders. However, simply
     attending the special meeting without voting will not revoke an earlier
     proxy.

If your shares are held in street name, you should follow the instructions of
your broker regarding revocation of proxies.

All shares represented by valid proxies, and not revoked, will be voted in
accordance with your instructions on the proxy card. If you sign your proxy
card, but make no specification on the card as to how you want your shares
voted, your proxy card will be voted "FOR" approval of the foregoing proposal.
The Board of Directors is presently unaware of any other matter that may be
presented for action at the special meeting of shareholders. If any other matter
does properly come before the special meeting, the Board of Directors intends
that shares represented by properly submitted proxies will be voted, or not
voted, by and at the discretion of the persons named as proxies on the proxy
card.

RECORD DATE

The close of business on _______________, 2006 has been fixed as the record date
for determining the Farwell shareholders entitled to receive notice of and to
vote at the special meeting of shareholders. At that time, __________ shares of
Farwell common stock were outstanding, and were held by approximately __________
holders of record.

VOTING RIGHTS, QUORUM REQUIREMENTS AND VOTE REQUIRED

The presence, in person or by properly executed proxy, of the holders of a
majority of the outstanding shares of Farwell common stock entitled to vote is
necessary to constitute a quorum at the special meeting of shareholders.
Abstentions and broker non-votes will be counted for the purpose of determining
whether a quorum is present but will not be counted as votes cast either for or
against the Merger Agreement.

Adoption of the Merger Agreement requires the affirmative vote of the holders of
66 2/3% of the shares of Farwell common stock issued and outstanding on the
record date. Accordingly, a failure to vote, an abstention or a broker non-vote
will have the same effect as a vote against the Merger Agreement. As of the
record date, directors and executive officers of Farwell beneficially owned
__________ shares of Farwell common stock entitled to vote at the special
meeting of shareholders. This represents approximately _____% of the total votes
entitled to be cast at the special meeting. These individuals have indicated
that they will vote "FOR" adoption of the Merger Agreement.

SOLICITATION OF PROXIES

For Farwell shareholders, the proxy that accompanies this document is being
solicited by Farwell's Board of Directors. In addition to solicitations by mail,
directors, officers, and regular employees of Farwell may solicit proxies from
shareholders personally or by telephone or other electronic means. Such
individuals will not receive any additional compensation for doing so. Farwell
will bear its own costs of soliciting proxies, which Farwell estimates will be
less than $20,000. Farwell also will make arrangements with brokers and other
custodians, nominees, and fiduciaries to send this document to beneficial owners
of Farwell common stock and, upon request, will reimburse those brokers and
other custodians for their reasonable expenses in forwarding these materials.

RECOMMENDATION OF THE BOARD OF DIRECTORS

Farwell's Board of Directors has unanimously approved the Merger Agreement and
the transactions contemplated by the Merger Agreement. The Board of Directors
believes that the Merger Agreement is fair to Farwell shareholders and is in the
best interest of Farwell and its


                                       12



shareholders and recommends that you vote "FOR" the approval of the Merger
Agreement. See "The Merger and the Merger Agreement-Recommendation of the
Farwell Board of Directors and Reasons for the Merger."

                       THE MERGER AND THE MERGER AGREEMENT

The description of the merger and the Merger Agreement contained in this proxy
statement-prospectus describes the material terms of the Merger Agreement;
however, it does not purport to be complete. It is qualified in its entirety by
reference to the Merger Agreement. We have attached a copy of the Merger
Agreement as Appendix A and urge you to carefully review it.

GENERAL

Pursuant to the Merger Agreement, Farwell will merge with and into Farmers, a
wholly-owned subsidiary of IBT. Outstanding shares of Farwell common stock will
be converted into the right to receive 3.0382 shares of IBT common stock and
$29.00 in cash, subject to adjustment under certain circumstances. Cash will be
paid in lieu of any fractional share of IBT common stock. See "Merger
Consideration" below. At the effective time of the merger, Farwell's corporate
existence will terminate; and Farmers will continue as the surviving bank with a
Board of Directors consisting of Dennis Angner, Michael McGuire, Dale Weburg,
James Fabiano and David Maness. The name of the surviving bank shall be FSB.

STOCK CERTIFICATES SHOULD BE RETURNED TO THE EXCHANGE AGENT IN ACCORDANCE WITH
THE INSTRUCTIONS CONTAINED IN THE LETTER OF TRANSMITTAL WHICH WILL BE PROVIDED

BACKGROUND OF MERGER

The terms and conditions of the Merger Agreement are the result of arm's length
negotiations between the representatives of Farmers and IBT and the
representatives of Farwell. A summary of the background of these negotiations is
set forth below.

     The Board of Directors and management of Farwell have periodically explored
the possibility of merging with another financial institution as part of the
ongoing fiduciary responsibility to its shareholders. During the past 15 years,
Farwell's management has had several conversations with IBT management about
becoming part of the IBT organization. In June 2003, the Board of Directors of
both institutions agreed to formally explore the potential of a merger. The
companies agreed to retain Austin Associates, LLC of Toledo, Ohio as a
facilitator.

     From July 2003 through July 2005, various discussions took place between
management and the Boards of Directors. These discussions included operating
philosophies, employee benefits, price and management of Farwell post-merger. As
a result of these discussions, the parties agreed to the price and the basic
structure of the transaction and, on October 3, 2005, executed a confidentiality
agreement. During October, November and December, 2005, the parties performed
due diligence and reviewed the draft of the definitive Merger Agreement. The
Board of Directors of both institutions agreed unanimously to sign the initial
agreement, which was signed on December 22, 2005.

     Subsequent to the initial agreement's signing, IBT and Farwell began
preparing the required regulatory applications. As part of the regulatory
application preparation process, legal counsel had discussions with the
supervisor of the research department of the Federal Reserve Bank of Chicago
(FRB). Based on these discussions, the likelihood that the FRB would approve the
merger was extremely poor due to anti-competitive deposit market concentration.
The market as defined by the FRB was extremely narrow and included only the
deposits of commercial bank branches in Clare and Isabella counties.

     Based on preliminary market research results, management of both
institutions believed that the FRB market area definition and restructuring the
market measurement to deposits only grossly overstated the anti-competitive
results of the proposed transaction. At the request of management, legal counsel
had discussions with the Federal Deposit Insurance Corporation (FDIC) about
their criteria and requirement to approve the proposed transaction. Based on the
criteria set forth by the FDIC and advice of legal counsel, Farwell and IBT
undertook further negotiations to change the structure of the transaction in
order to move the regulatory venue to the FDIC.

     On March 6, 2006, the parties agreed in principal on the restructuring of
the initial agreement. The restructured transaction as set forth in the Merger
Agreement involves the merger of Farwell with and into Farmers, a wholly owned
subsidiary of IBT. As a result of the merger, Farmers will change its name to
FSB Bank. The revised structure and changes to the initial agreement were
unanimously approved by the Board of Directors of Farmers on April 19, 2006, by
the IBT Board on April 18, 2006 and the Farwell Board on May 2, 2006; and the
Merger Agreement was signed on May 2, 2006.

RECOMMENDATION OF FARWELL'S BOARD OF DIRECTORS AND REASONS FOR THE MERGER

The Board of Directors of Farwell has approved the Merger Agreement and has
determined that the merger is fair to and in the best interests of Farwell and
its shareholders. In reaching its decision to approve the Merger Agreement, the
Board of Directors consulted with its outside counsel regarding the legal terms
of the merger and the Board of Director's fiduciary obligations in its
consideration of the proposed merger, considered the financial aspects and
fairness of the proposed Merger Agreement from a financial point of view and
consulted with the management of Farwell regarding the future prospects of
Farwell as an independent entity and as part of IBT. Without assigning any
relative or specific weight, the Board of Directors of Farwell considered a
number of factors, including the following both from a short-term and long-term
perspective:

-    The merger consideration to be paid to Farwell shareholders;

-    The structure of the merger and the financial and other terms of the Merger
     Agreement, including the fact that the merger is conditioned upon Farwell's
     receipt of financial analysis and opinions to be delivered by Austin
     Associates, LLC and Donnelly, Penman & Partners that the terms of the
     Merger Agreement are fair to the shareholders of Farwell from a financial
     point of view;

-    The fact that the transaction was structured to keep Farwell's offices open
     and to provide that no employee would be laid off;


                                       14



-    The Board of Directors reviews, with its legal and financial advisors, of
     alternatives to the merger, the range and possible value to Farwell
     shareholders obtainable through such alternatives and the timing and
     likelihood of the alternatives.

-    The familiarity of the Board of Directors of Farwell with, and review of,
     its business, financial condition, results of operations and prospects,
     including, but not limited to, its potential growth, development,
     productivity and profitability and the business risks associated with the
     merger;

-    The current and prospective environment in which Farwell operates,
     including national and local economic conditions, the highly competitive
     environment for financial institutions generally, the increased regulatory
     burden on financial institutions, the trend toward consolidation in the
     financial services industry, and the increasing importance of operational
     scale and financial resources in maintaining efficiency, remaining
     competitive, and capitalizing on technological developments.;

-    The potential for appreciation in market and book value of Farwell's common
     stock on both a short- and long-term basis, as a stand-alone entity;

-    Information concerning IBT's management, business, financial condition,
     results of operations, asset quality and prospects, including the long-term
     growth potential of IBT, the future growth prospects of IBT combined with
     Farwell following the proposed merger, the potential synergies expected
     from the merger and the business risks associated with the merger;

-    The United States federal income tax consequences to Farwell shareholders
     of receiving the merger consideration in exchange for their shares of
     Farwell common stock;

-    The advantages and disadvantages of Farwell remaining an independent
     institution or affiliating with a larger institution;

-    The short- and long-term interests of Farwell and its shareholders, the
     interests of the employees, customers, creditors and suppliers of Farwell,
     and the interests of Farwell's community, all of which may benefit from an
     appropriate affiliation with a larger institution with increased economies
     of scale and with a greater capacity to serve all of the banking needs of
     the community;

-    The fact that some of Farwell's directors and executive officers have
     interests in the merger that are in addition to and may differ from the
     interests of Farwell shareholders. See "Interests of Directors and Officers
     In the Merger"; and

-    The compatibility of the businesses and management philosophies of Farwell
     and IBT and IBT's strong commitment to the communities it serves.

On the basis of these considerations, the Merger Agreement was unanimously
approved by Farwell's Board of Directors.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS ADOPTION OF THE AGREEMENT AND PLAN
OF MERGER BY THE SHAREHOLDERS OF FARWELL.

          Statement/Prospectus is qualified in its entirety by reference to the
          full text of the opinion that is attached as Appendix B to this
          document. You should read the opinion in its entirety for a full
          discussion of the procedures followed, assumptions made, matters
          considered and qualifications and limitations of the review undertaken
          by AAL in connection with its opinion.

     -    AAL expressed no opinion as to the price at which IBT common stock
          would actually be trading at any time.

     -    The AAL opinion does not address the relative merits of the Merger and
          the other business strategies considered by IBT or Farwell, nor does
          it address the IBT or Farwell board decision to proceed with the
          Merger.

     -    The AAL opinion to the IBT and Farwell boards rendered in connection
          with the Merger does not constitute a recommendation to any Farwell
          shareholder as to how he or she should vote at the special meeting.

In connection with its opinion, AAL made the following assumptions:

     -    that the Merger will be accounted for as a "purchase" in accordance
          with generally accepted accounting principles;

     -    that all material governmental, regulatory and other consents and
          approvals necessary for the consummation of the Merger would be
          obtained without any adverse effect to IBT, Farwell or on the
          anticipated benefits of the Merger;

     -    that IBT and Farwell had provided it with all of the information
          prepared by IBT and Farwell or its other representatives that might be
          material to AAL in its review; and

     -    that the financial projections it reviewed were reasonably prepared on
          a basis reflecting the best currently available estimates and judgment
          of the management of IBT and Farwell as to the future operating and
          financial performance of IBT and Farwell, respectively.

In addition, AAL:

     -    reviewed the Merger Agreement and publicly available business and
          financial information relating to IBT and Farwell that it considered
          relevant;

     -    reviewed other information relating to IBT and Farwell, including
          internal financial forecasts and forecasts of cost savings to be
          achieved in the merger;

     -    held discussions with IBT and Farwell management related to the
          business and prospects of the pro forma company;

     -    considered financial and stock market information about IBT and
          Farwell and compared that information with similar information about
          other publicly traded financial institutions;

     -    considered the financial terms of other recent business combinations
          among financial institutions; and

     -    considered such other studies, analyses, inquiries and examinations as
          AAL deemed appropriate.

In connection with its review, AAL did not assume any responsibility for
independent verification of any of the information provided to or otherwise
reviewed by AAL. AAL relied on this information being complete and accurate in
all material respects. As to the financial forecasts, including the estimates of
future cost savings expected to be achieved as a result of the merger, AAL
assumed that these forecasts were reasonably prepared and reflected the best
currently available estimates and judgments of the management of IBT and Farwell
as to the future financial performance of IBT and Farwell. In addition, IBT and
Farwell did not ask AAL to make, and AAL did not make, an


                                       16



independent evaluation or appraisal of the assets or liabilities, contingent or
otherwise, of IBT or Farwell, nor was AAL furnished with any evaluations or
appraisals of this kind. IBT and Farwell placed no limits on the scope of
analysis performed, or opinion expressed, by AAL.

In preparing its opinion, AAL performed a variety of financial and comparative
analyses, the material aspects of which are described below. The preparation of
a fairness opinion is a complex analytic process involving various
determinations as to the most appropriate and relevant methods of financial
analyses and the application of those methods to the particular circumstances.
Therefore, such an opinion is not readily susceptible to partial analysis or
summary description. In arriving at its opinion, AAL made qualitative judgments
as to the significance and relevance of each analysis and factor considered by
it. Accordingly, AAL believes that its analyses must be considered as a whole
and that selecting portions of its analyses and factors, without considering all
analyses and factors, could create a misleading or incomplete view of the
process underlying its analyses and its opinion.

The following is a summary of the material financial analyses performed by AAL
in connection with its written opinion rendered to the IBT and Farwell boards of
directors as of _______ __, 2006. Certain of these summaries include information
presented in tabular format. In order to fully understand the financial analyses
used by AAL, these tables must be read together with the accompanying narrative.
The tables alone do not constitute a complete description of the applicable
financial analysis.

SUMMARY OF FINANCIAL TERMS OF AGREEMENT: AAL reviewed the financial terms of the
proposed transaction, including the form of consideration and the exchange
ratio. Under the terms of the Merger Agreement, each outstanding share of
Farwell common stock shall be exchanged for 3.0382 shares of IBT common stock
plus $29.00 in cash. Based on a market price of $43.00 for each IBT share (as of
May 2, 2006), the market value of the total transaction consideration payable to
Farwell shareholders is $159.64 per share, or $41.9 million in the aggregate for
100% of Farwell shares. Farwell reported 262,500 shares outstanding at March 31,
2006. No fractional shares of IBT common stock shall be issued in the Merger.
Cash will be paid in lieu of fractional shares based on the value of IBT common
stock of $42.00 per share.

PREPARATION OF FINANCIAL ANALYSIS: In connection with AAL's role as financial
advisor, AAL prepared various financial analyses as summarized below. These
analyses were based on March 31, 2006 financial information.

     CONTRIBUTION ANALYSIS: The contribution analysis performed by AAL compares
     the relative contribution of key balance sheet and income statement
     measures by IBT and Farwell to the pro-forma company. AAL also compared the
     contribution of market value as determined by IBT's current market
     capitalization and Farwell's value as determined in the transaction with
     IBT.



                                        IBT             FARWELL

(1)  IBT's market value based on $43.00 per share times 5,484,324 shares
     outstanding. Farwell's market value based on 3.0382 shares of IBT common
     stock for each share of Farwell plus $29.00 in cash. Farwell reported
     262,500 shares outstanding.

The range of contribution from Farwell in terms of assets, equity and net income
ranges from 10.7 percent to 18.5 percent in the pro forma company. The actual
market value contribution of Farwell equals 15.1 percent.

RELATIVE DISCOUNTED CASH FLOW VALUES: AAL calculated discounted cash flow
("DCF") values of both IBT and Farwell, and computed the relative DCF value
contribution of each organization to the combined company. The DCF value of IBT
was computed on the basis of a stand-alone, going concern company. The
calculation is based on a five year projection of key financial inputs including
total assets, net income and capital levels, among other variables. The
projected cash flows and residual value are discounted to a present value under
this methodology. The following provides highlights for the projected
performance of IBT:

Note: LTM = last twelve months

AAL determined the resulting aggregate DCF value of IBT at $112.7 million.

A DCF analysis of Farwell was prepared on a control level basis by computing a
stand-alone value for the company and adding the present value of potential cost
savings related to the Merger. The following provides highlights for the key
assumptions used in this analysis:



               ACTUAL                 PROJECTED LTM ENDING ($000)
                 LTM     ----------------------------------------------------

-----------   --------   --------   --------   --------   --------   --------
                                                   
Assets         $91,550    $94,297    $97,125   $100,039   $103,040   $106,132
Net Income     $ 1,506    $ 1,474    $ 1,518   $  1,564   $  1,611   $  1,659
ROAA              1.65%      1.59%      1.59%      1.59%      1.59%      1.59%


Based on these performance assumptions, AAL determined the resulting DCF value
of Farwell, on a stand-alone basis, equal to $20.1 million. AAL also calculated
the present value of potential cost savings in connection with the Merger. AAL
considered pre-tax cost savings equal to 4.6 percent of Farwell's operating
expenses in the first year after the Merger, and 6.4 percent thereafter.
Combining the stand-alone DCF value of Farwell with the present value of
potential cost savings resulted in a pro forma DCF value of $21.7 million.

The following table provides the resulting DCF values for both IBT and Farwell
and the respective contribution to the pro forma company.



                IBT (STAND-ALONE)      FARWELL (SALE OF CONTROL)

$134,359     $112,679       83.9%        $21,680       16.1%


The above table indicates the relative DCF value contribution of Farwell in the
pro forma company is 16.1 percent. This compares to the actual Farwell market
value contribution of 15.1 percent.

MARKET PREMIUM ANALYSIS FOR IBT: AAL compared the price-to-book and
price-to-core earnings multiples of IBT to guideline peer companies. AAL
utilized two guideline peer groups under this approach. The first guideline peer
group consisted of six Michigan publicly traded banks with assets between $500
million and $1.5 billion and last twelve-month core return on average equity
("ROAE") greater than 5 percent. The second guideline peer group consisted of 41
Midwest publicly traded banks with assets between $500 million and $1 billion
and last twelve-month core ROAE between 5 and 15 percent. The following table
provides the median financial and stock price data of the guideline peer groups
compared to IBT. IBT stock trades at a substantial premium to the median trading
multiples of both the Michigan and Midwest peer organizations.

stock trades at a premium of 127 percent to 132 percent over the peer median
price-to-last twelve months ("LTM") core earnings per share.

MARKET PREMIUM ANALYSIS FOR FARWELL: AAL compared the price-to-book and
price-to-LTM earnings multiples being received by Farwell shareholders in the
Merger to guideline peer companies. AAL also utilized two guideline peer groups
under this approach. The first guideline transaction peer group consisted of 31
Midwest bank deals announced from January 1, 2004 through May 2, 2006 with
seller's assets between $50 and $250 million, year-to-date return on average
assets ("ROAA") greater than 0.5 percent, and tangible equity to assets greater
than 8.0 percent. The second guideline transaction group was based on a national
listing of sale transactions which consisted of 27 bank deals announced from
January 1, 2004 to May 2, 2006 with the seller's assets between $75 and $150
million, year-to-date ROAA greater than 0.75 percent, and tangible equity to
tangible assets greater than 10.0 percent. The following table provides the
median financial and deal pricing multiples for the guideline transaction peer
groups compared to the pricing multiples being received by Farwell shareholders
in the Merger.

over the guideline transaction multiples.

APPLICATION OF GUIDELINE PRICING MULTIPLES AND RESULTING CONTRIBUTION ANALYSIS:
AAL reviewed the guideline peer groups identified in the above tables and
applied current market pricing multiples to both IBT and Farwell book value and
earnings levels. AAL utilized minority share guideline transaction multiples for
IBT and control level multiples for Farwell. The guideline pricing multiples
assigned to each company were subjectively determined after consideration of the
respective underlying performance characteristics of both IBT and Farwell. AAL
computed the aggregate value of each company using the selected
price-to-tangible


                                       19



book and price-to-earnings multiples. The following chart summarizes the
aggregate results and the resulting contribution that each company would make to
the combined organization:



                        IBT        %    FARWELL     %
                      --------   ----   -------   ----

PRICE/LTM EARNINGS    $ 99,705   82.5%  $21,084   17.5%


     The above table indicates a contribution by Farwell ranging from 14.1
     percent to 17.5 percent using guideline transaction-based market values.
     This compares to the actual Farwell market value contribution of 15.1
     percent.

     The opinion expressed by AAL was based on market, economic and other
relevant considerations as they existed and could be evaluated as of the date of
the opinion. Events occurring after the date of issuance of the opinion,
including but not limited to, changes affecting the securities markets, the
results of operations or material changes in the financial condition of either
IBT or Farwell could materially affect the assumptions used in preparing this
opinion.

     IBT and Farwell have agreed to pay AAL customary fees for its services as
financial advisor in connection with the Merger. In addition to its fees and
regardless of whether the merger is consummated, IBT and Farwell have agreed to
reimburse AAL for its reasonable out-of-pocket expenses, and to indemnify AAL
against certain liabilities, including liabilities under securities laws.


FAIRNESS OPINION OF DONNELLY PENMAN & PARTNERS

Farwell retained Donnelly Penman & Partners ("Donnelly Penman") to act as
Farwell's financial advisor in connection with the merger and related matters
based upon its qualifications, expertise and reputation, as well as its
familiarity with Farwell. Donnelly Penman is a recognized investment banking and
advisory firm. As a part of its investment banking and advisory business,
Donnelly Penman is continually engaged in the valuation of businesses and
securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements and valuations for estate, corporate and
other purposes.

On December 22, 2005 IBT, a bank holding company headquartered in Mt. Pleasant,
Michigan and Farwell announced that they had entered into an Agreement and Plan
of Merger (the "Agreement") to which IBT would acquire Farwell. On May 2, 2006
IBT, Farmers, a subsidiary of IBT, and Farwell entered into an amended and
restated Agreement and Plan of Merger (the "Merger Agreement") to substitute
Farmers as the acquiring entity. In accordance with the terms of the Merger
Agreement, Farwell will merge with Farmers with Farmers as the surviving entity.
Concurrently, each share of Farwell common stock issued and outstanding
immediately prior to the effective time of the merger shall be converted into
the right to receive 3.0382 shares of IBT common stock plus $29.00 in cash.
Donnelly Penman has delivered its opinion that the exchange ratio and cash
consideration received is fair to Farwell's shareholders from a financial point
of view. No limitations were imposed by Farwell on the scope of Donnelly
Penman's investigation or on the procedures followed by Donnelly Penman in
rendering its opinion.

THINGS, ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED AND LIMITS ON
THE REVIEW UNDERTAKEN BY DONNELLY PENMAN, IS ATTACHED AS APPENDIX C TO THIS
PROXY STATEMENT-PROSPECTUS. HOLDERS OF FARWELL COMMON STOCK ARE URGED TO READ
THE OPINION IN ITS ENTIRETY. DONNELLY PENMAN'S OPINION IS DIRECTED ONLY TO THE
MERGER CONSIDERATION DESCRIBED IN THE MERGER AGREEMENT AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY FARWELL SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD VOTE
AT THE FARWELL SPECIAL SHAREHOLDER MEETING. THE SUMMARY SET FORTH IN THIS PROXY
STATEMENT-PROSPECTUS OF THE OPINION OF DONNELLY PENMAN IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE FULL TEXT OF ITS OPINION ATTACHED TO THIS DOCUMENT
AS APPENDIX C.

In arriving at its opinion, Donnelly Penman engaged in discussions with members
of the management of each of Farwell and IBT concerning the historical and
current business operations, financial conditions and prospects of Farwell and
IBT and reviewed:

         o        the Agreement and Plan of Merger dated December 22, 2005 and
                  the Amended and Restated Agreement and Plan of Merger dated
                  May 2, 2006;

         o        the most recent draft dated June 29, 2006 of the Form S-4
                  Registration Statement relating to the merger;

         o        certain publicly-available information for IBT, including each
                  of the Annual Reports to Stockholders and Annual Reports on
                  Form 10-K for the years December 31, 2003, 2004 and 2005 and
                  the quarterly reports on Form 10-Q for the quarter ended March
                  31, 2006;

         o        certain information, including financial forecasts, relating
                  to earnings, assets, liabilities and prospects of IBT
                  furnished by senior management of IBT;

         o        Independent Auditor's Report for Farwell State Bank for the
                  years ended December 31, 2005 and 2004 and the unaudited
                  condensed balance sheet and statement of income for the three
                  months ended March 31, 2006 and March 31, 2005;

         o        certain information, including financial forecasts, relating
                  to earnings, assets, liabilities and prospects of Farwell
                  furnished by senior management of Farwell;



                                       20




         o        IBT's senior management projected earnings estimates for
                  fiscal years 2006 through 2010, which were deemed reasonable
                  by IBT management;

         o        Farwell's senior management projected earnings estimates for
                  fiscal years 2006 through 2010, which were deemed reasonable
                  by Farwell management;

         o        the amount and timing of the cost savings expected to result
                  from the merger furnished by senior management of IBT;

         o        the financial condition and operating results of IBT and
                  Farwell compared to the financial conditions and operating
                  results of certain other financial institutions that Donnelly
                  Penman deemed comparable;

         o        various valuation analyses of Farwell and IBT Donnelly Penman
                  performed including dividend discount analyses, analysis of
                  comparable transactions and analysis of comparable companies;
                  and

         o        such other information, financial studies, analyses and
                  investigations and such other factors that Donnelly Penman
                  deemed relevant for the purposes of its opinion.

In conducting its review and arriving at its opinion, as contemplated under the
terms of its engagement by Farwell, Donnelly Penman, with the consent of IBT and
Farwell, relied, without independent investigation, upon the accuracy and
completeness of all financial and other information provided to it by IBT and
Farwell or upon publicly-available information. Donnelly Penman did not
undertake any responsibility for the accuracy, completeness or reasonableness
of, or any obligation independently to verify, such information. Donnelly Penman
further relied upon the assurance of management of IBT and Farwell that they
were unaware of any facts that would make the information provided or available
to Donnelly Penman incomplete or misleading in any respect. Donnelly Penman did
not make any independent evaluations, valuations or appraisals of the assets or
liabilities of IBT or Farwell. Donnelly Penman did not review any individual
credit files of IBT or Farwell and assumed that the aggregate allowances for
credit losses for IBT and Farwell were adequate to cover such losses. Donnelly
Penman's opinion was necessarily based upon economic and market conditions and
other circumstances as they existed and were evaluated by Donnelly Penman on the
date of its opinion. Donnelly Penman does not have any obligation to update its
opinion, unless requested by Farwell in writing to do so, and Donnelly Penman
expressly disclaims any responsibility to do so in the absence of any written
request by Farwell.

In connection with rendering its opinion to the Farwell Board, Donnelly Penman
performed a variety of financial analyses, which are summarized below. Donnelly
Penman believes that its analyses must be considered as a whole and that
selecting portions of its analyses and the factors considered by it, without
consideration of all factors and analyses, could create a misleading view of the
analyses and the processes underlying Donnelly Penman's opinion. Donnelly Penman
arrived at its opinion based on the results of all the analyses it undertook
assessed as a whole, and it did not draw conclusions from or with regard to any
one method of analysis. The preparation of a fairness opinion is a complex
process involving subjective judgments, and is not necessarily susceptible to
partial analysis or summary description. With respect to the analysis of
selected comparable companies and analysis of selected comparable merger of
equal transactions summarized below, no public company utilized as a comparison
is identical to IBT or Farwell, and such analyses necessarily involve complex
considerations and judgments concerning the differences in financial and
operating characteristics of the relevant financial institutions and other
factors that could affect the acquisition or public trading values of the
financial institutions concerned.


                                       21



The financial forecast information and cost savings and other synergies expected
to result from the merger furnished by management of IBT and Farwell,
respectively, and deemed reasonable by them contained in or underlying Donnelly
Penman's analyses are not necessarily indicative of future results or values,
which may be significantly more or less favorable than such forecasts and
estimates. The forecasts and estimates were based on numerous variables and
assumptions that are inherently uncertain, including factors related to general
economic and competitive conditions. In that regard, Donnelly Penman assumed,
with IBT's and Farwell's consent, that the financial forecasts, including the
cost savings and other synergies expected to result from the merger, were
reasonably prepared on a basis reflecting the best currently available judgments
of IBT and Farwell, and that such forecasts will be realized in the amounts and
at the times that they contemplate. The estimates contained in Donnelly Penman's
analyses are not necessarily indicative of actual values or future results,
which may be significantly more or less favorable than those suggested by those
analyses. Estimates of values of financial institutions or assets do not purport
to be appraisals or necessarily reflect the prices at which financial
institutions or their securities actually may be sold. Accordingly, actual
results could vary significantly from those assumed in the financial forecasts
and related analyses. None of the analyses performed by Donnelly Penman was
assigned a greater significance by Donnelly Penman than any other.

The following is a brief summary of the analyses performed by Donnelly Penman.
Certain analyses have been updated to reflect currently available information
for purposes of the written fairness opinion.

SUMMARY ANALYSIS OF THE TRANSACTION

The Merger Agreement provides that each share of Farwell common stock issued and
outstanding immediately prior to the effective time of the merger shall be
converted into the right to receive 3.0382 shares of IBT common stock plus
$29.00 in cash.

Donnelly Penman reviewed the terms of the merger. It noted that the exchange
ratio of 3.0382 shares of IBT common stock for each share of Farwell common
stock and cash consideration of $29.0 per share meant that the transaction had
an implied per share value of $145.00 for each share of Farwell common stock
based upon the closing price of IBT of $38.18 on December 15, 2005. This implied
per share value represents a 277.2% premium to the book value per Farwell share
of $52.31 as of March 31, 2006. Donnelly Penman also noted that, based on the
exchange ratio and cash consideration the transaction had an implied aggregate
value of approximately $38.1 million (exclusive of transaction costs) as of
December 15, 2005. The complete aggregate deal metrics in relation to the
Farwell financial position as of March 31, 2006 are displayed below:



                                  FOR THE TWELVE MONTHS ENDED MARCH 31, 2006

                                       22


Donnelly Penman also noted, when considering the most recent trading based upon
the closing price of IBT of $45.00 on June 28, 2005 that the exchange ratio of
3.0382 shares of IBT common stock for each share of Farwell common stock and
cash consideration of $29.00 per share meant that the transaction had an implied
per share value of $165.72 for each share of Farwell common stock. This implied
per share value represents a 316.8% premium to the book value per Farwell share
of $52.31 as of March 31, 2006.

Donnelly Penman also noted, when considering the value of the transaction based
on an implied equity value per share of IBT of $23.79 that the exchange ratio of
3.0382 shares of IBT common stock for each share of Farwell common stock and
cash consideration of $29.00 per share meant that the transaction had an implied
per share value of $101.28 for each share of Farwell common stock. This implied
per share value represents a 193.6% premium to the book value per Farwell share
of $52.31 as of March 31, 2006. The $23.79 implied per share value for IBT is
based on an assumed price to tangible book multiple of 1.66 times IBT's tangible
book value of $14.33 as of March 31, 2006. The price to tangible book multiple
is based on a review of the multiples for select publicly traded Midwest
commercial banks with assets of $500 million to $1 billion and a return on
average equity between 8% and 12%.

Donnelly Penman also noted, when considering the value of the transaction based
on an implied equity value per share of IBT of $20.34 that the exchange ratio of
3.0382 shares of IBT common stock for each share of Farwell common stock and
cash consideration of $29.00 per share meant that the transaction had an implied
per share value of $90.80 for each share of Farwell common stock. This implied
per share value represents a 173.6% premium to the book value per Farwell share
of $52.31 as of March 31, 2006. The $20.34 implied per share value for IBT is
based on a discounted dividend analysis. This analysis utilized a range of
discount rates of 11.0% to 14.0% and a range of terminal value multiples of 14.0
to 17.0 times projected 2010 net income. The discount rate was derived from the
Ibbotson and Associates 20051 data on cost of equity buildup (and sensitized a
range of 11.0%-14.0%). The terminal multiple range was determined by reviewing
the multiples for select publicly traded placeMidwest commercial banks with
assets between $500 million and $1 billion and return on average equity between
8% and 12%.

ANALYSIS OF SELECTED COMPARABLE COMPANIES

Donnelly Penman compared selected financial and operating results of Farwell to
a peer group that included the following 18 exchange traded commercial banks in
Illinois, Indiana, Michigan, Ohio and Wisconsin, which were selected based on
comparable asset size and financial returns. Specifically the peer group
identified had assets less than $250 million and a last twelve month's return on
average equity between 8% and 12%. The peer group had median trading multiples
of 139.2% of book value per share, 139.2% of tangible book value per share and
16.79 times last twelve months earnings per share. These peer companies
consisted of:

     -   American Community Bancorp (ACBP)
     -   Capital Directions, Incorporated (CTDN)
     -   Century Financial Corporation (CYFL)
     -   ChoiceOne Financial Corporation (COFS)
     -   Community National Corporation (CMNC)
     -   Community Shores Bank Corporation (CSHB)
     -   Communibanc Corporation (CBCZ)
     -   Consumers Bancorp, Inc. (CBKM)
     -   CSB Bancorp, Inc. (CBMI)
     -   Eastern Michigan Financial Corporation (EFIN)
     -   F & M Bancorp (FMOO)
     -   FNB, Inc. (FIDS)
     -   Heartland Bancshares, Inc. (HRTB)
     -   ICNB Financial Corporation (ICNB)
     -   Layton Park State Bank (LTPM)
     -   Ohio Heritage Bancorp, Inc. (OHHB)
     -   United Commerce Bancorp (UCBN)
     -   Western Reserve Bancorp, Inc. (WRBO)

This comparison showed, among other things, that for the latest twelve months
ended March 31, 2006:

         o        Farwell's net interest margin was 3.94%, compared with the
                  Farwell peer group median of 4.06%;

         o        Farwell's efficiency ratio was 43.96%, compared with the
                  Farwell peer group median of 68.61%;

         o        Farwell's return on average assets was 1.65%, compared to the
                  Farwell peer group median of 0.88%;

         o        Farwell's return on average equity was 10.95%, compared to the
                  Farwell peer group median of 9.30%; and

         o        Farwell's ratio of nonperforming assets to total assets was
                  0.11%, compared with the Farwell peer group median of 0.42%.


No financial institution used in the above analyses as a comparison is identical
to Farwell. Accordingly, an analysis of the results of the foregoing necessarily
involves complex considerations and judgments concerning differences in
financial and operating characteristics of the companies and other factors that
could affect the public trading values of Farwell and the financial institutions
to which it was compared.



                                       24



ANALYSIS OF SELECTED COMPARABLE TRANSACTIONS

Donnelly Penman reviewed and compared actual information for 19 completed or
pending bank merger transactions announced from a period of January 1, 2003 to
December 31, 2005. Furthermore, the transactions listed involved commercial
banks located in Illinois, Indiana, Michigan, Ohio and Wisconsin with total
assets less than $250 million and a last twelve month's return on average equity
of between 8% and 12%. These transactions consisted of:

(Buyer/Seller)
     -    MainSource Financial Group/ HFS Bank FSB
     -    Hometown Community Bncp Inc/ Progressive Bancorp Inc.
     -    River Holding Co./ Farmers State Bancshares Inc.
     -    Peotone Bancorp Inc./ Vermilion Bancorp Inc.
     -    Princeton National Bancorp/ Somonauk FSB Bancorp Inc.
     -    Peoples Community Bancorp Inc./ American State Corporation
     -    Park National Corp./ First Clermont Bank
     -    Webster Financial Corp./ Eastern Wisconsin Bcshrs Inc.
     -    Croghan Bancshares Inc./ Custar State Bank
     -    Wintrust Financial Corp./ Town Bankshares Ltd
     -    Camco Financial Corp./ London Financial Corp.
     -    Lincoln Bancorp/ First Shares Bancorp Inc.
     -    Harrodsburg First Fin Bancorp/ Independence Bancorp
     -    Van Orin Bancorp Inc./ Malden Bancorp Inc.
     -    State Financial Services Corp./ Lakes Region Bancorp Inc.
     -    Citizens First Bancorp Inc./ Metro Bancorp, Inc.
     -    Blackhawk Bancorp Inc./ DunC Corp.
     -    Carlinville Natl Bk Shares Inc/ Cornerstone Bank & Trust, NA
     -    JW Bancorp Inc./ John Warner Financial Corp.

This comparison showed that based on the transaction price calculated above
compared with Farwell's financial condition as of March 31, 2006:

         o        The transaction price to last twelve months earnings multiple
                  was 25.3 times, compared with the comparable transaction group
                  median of 20.0 times last twelve month's earnings;

         o        The transaction price was 277.2% of book value, compared with
                  the comparable transaction group median of 181.06%;

         o        The transaction price was 277.2% of tangible book value,
                  compared with the comparable transaction group median of
                  181.06%;

         o        The transaction price was 41.6% of total assets, compared with
                  the comparable transaction group median of 17.9%;

         o        The transaction price was 49.6% of deposits, compared with the
                  comparable transaction group median of 22.3%; and

         o        The transaction price represented a 40.4% premium to core
                  deposits, compared with the comparable transaction group
                  median of 12.7%.

Donnelly Penman recognized that no transaction reviewed was identical to the
merger and that, accordingly, any analysis of comparable transactions
necessarily involves complex considerations and judgments concerning differences
in financial and operating characteristics of the parties to the transactions
being compared.




                                       25


DIVIDEND DISCOUNT ANALYSIS - FARWELL

Donnelly Penman calculated an estimated range of equity values per share for
Farwell based upon the values, discounted to the present, of estimates of
projected dividends from the fiscal year ending December 31, 2006 through the
fiscal year ending December 31, 2010 and a projected year 2010 terminal value
assuming Farwell continued to operate as an independent company. The valuation
date contemplated is July 1, 2006, with half of the 2006 dividends being paid in
the last six months of the year. In conducting its analysis, Donnelly Penman
utilized financial estimates provided by and deemed reasonable by Farwell and
IBT for 2006 through 2010. Donnelly Penman further assumed, with Farwell senior
management's consent, a $3.25 dividend payment per share in 2006 and each year
thereafter. Additionally, Donnelly Penman assumed that Farwell could pay a one
time special dividend at the beginning of the projection period. This special
dividend was estimated by Donnelly Penman as the excess capital that could be
distributed to shareholders and still leave Farwell at a 6.5% capital to assets
ratio. Then, estimated net income was reduced by the impact of the cost of cash
on the projected earnings.

This analysis utilized a range of discount rates of 11.0% to 14.0% and a range
of terminal value multiples of 14.0 to 17.0 times projected 2010 net income. The
discount rate was derived from the Ibbotson and Associates 20052 data on cost of
equity buildup and sensitized to the base cost of equity of 12% provided from
the Ibbotson and Associates Research (a range of 11.0%-14.0% was utilized). The
terminal multiple range was determined by reviewing the multiples for select
publicly traded Midwest commercial banks with assets less than $250 million and
return on average equity between 8% and 12%. The analysis resulted in a range of
present values between $92.30 and $103.23 per share.

The analysis was based upon Farwell and IBT senior management's projections of
future performance on a stand alone basis, which were based upon many factors
and assumptions deemed reasonable by Farwell and IBT senior management. This
analysis did not purport to be indicative of actual values or actual future
results and did not purport to reflect the prices at which any securities may
trade at the present or at any time in the future. Donnelly Penman included this
analysis because it is a widely used valuation methodology, but noted that the
results of such methodology are highly dependent upon the numerous assumptions
that must be made, including earnings growth rates, dividend payout rates,
terminal values and discount rates.


For its financial advisory services provided to Farwell, Donnelly Penman has
been paid ordinary and customary fees at or before the closing of the merger. In
addition, Farwell has agreed to indemnify Donnelly Penman against various
liabilities, including any which may arise under the federal securities laws.

be required to register the shares in that manner until it has received all of
your old Farwell stock certificates (or an affidavit of loss for such

executed transmittal materials. Such




                                       27


old Farwell stock certificates, transmittal materials, and affidavits must be in
a form and condition reasonably acceptable to IBT and the exchange agent. The
exchange agent will have discretion to determine reasonable rules and procedures
relating to the exchange (or lack thereof) of old Farwell stock certificates and
the payment of the per share merger consideration.

CONDUCT OF BUSINESS PENDING THE MERGER

The Merger Agreement contains various restrictions on the operations of Farwell
before the effective time of the merger. In general, the Merger Agreement
obligates Farwell to conduct its business in the usual, regular and ordinary

REGULATORY APPROVALS REQUIRED FOR THE MERGER

Farwell and Farmers have agreed to use all reasonable efforts to obtain all
permits, consents, approvals and authorizations of all third parties and
governmental entities that are necessary or advisable to consummate the merger.
This includes the approval or non-objection of the Federal Deposit Insurance
Corporation and the Office of Financial and Insurance Services of the State of
Michigan. Farmers has filed the application or notice materials necessary to
obtain these regulatory approvals. The merger cannot be completed without such
approvals and non-objections. Farmers cannot assure that it will obtain the
required regulatory approvals and non-objections, when they will be received, or
whether there will be conditions in the approvals or any litigation challenging
the approvals. Farwell and Farmers also cannot assure that the Federal Deposit
Insurance Corporation will not attempt to challenge the merger on antitrust
grounds, or what the outcome will be if such a challenge is made.

Farwell and Farmers are not aware of any material governmental approvals or
actions that are required prior to the merger other than those described above.
Farwell and Farmers presently contemplate that they will seek any additional
governmental approvals or actions that may be required in addition to those
requests for approval currently pending; however, they cannot assure that they
will obtain any such additional approvals or actions.

NO SOLICITATION

Until the merger is completed or the Merger Agreement is terminated, Farwell has
agreed that it, its officers, directors employees, representatives or agents
will not:

-    initiate, solicit or knowingly encourage any inquiries or the making of any
     acquisition proposal;

-    enter into, maintain or continue any discussions or negotiations regarding
     any acquisition proposals; or

-    agree to or endorse any other acquisition proposal.

Farwell may, however, furnish information regarding Farwell to, or enter into
and engage in discussion with, any person or entity in response to an
unsolicited proposal by the person or entity relating to an acquisition proposal
if:

-    Farwell's Board of Directors determines in good faith that such proposal,
     if consummated, is reasonably likely to result in a transaction more
     favorable from a financial point-of-view to Farwell's shareholders than the
     Farmers' merger;

-    Farwell's Board of Directors determines in good faith, after consultation
     with its legal counsel and financial advisors, that the action is required
     for Farwell's directors to comply with their fiduciary obligations under
     applicable law; and

-    Farwell promptly notifies Farmers of such inquiries, proposals or offers,
     the material terms of such inquiries, proposals or offers and the identity
     of the person making such inquiry, proposal or offer.

TERMINATION; AMENDMENT; WAIVER

The Merger Agreement may be terminated prior to the closing, before or after
approval by Farwell's shareholders, as follows:

-    by mutual written agreement of Farmers and Farwell;

-    by Farmers or Farwell if Farwell shareholders do not approve the Merger
     Agreement and merger;


                                       31


-    by a non-breaching party if the other party (1) materially breaches any
     covenants or undertakings contained in the Merger Agreement or (2)
     materially breaches any representations or warranties contained in the
     Merger Agreement, in each case if such breach by its nature cannot be cured
     prior to December 31, 2006 or has not been cured within thirty days after
     written notice from the terminating party;

-    by either party if any required regulatory approvals for consummation of
     the merger is not obtained;

-    by either party if the closing does not occur by December 31, 2006;

-    by either party if any condition to closing cannot be satisfied or
     fulfilled by December 31, 2006;

-    by Farmers if Farwell shall have received a superior proposal and Farwell
     Board of Directors shall have entered into an acquisition agreement with
     respect to a superior proposal and terminates the Merger Agreement or fails
     to recommend that the shareholders of Farwell approve the Merger Agreement
     or has withdrawn, modified or changed such recommendation in a manner which
     is adverse to Farmers; or

-    by Farwell in order to accept a "superior proposal," as defined in the
     Merger Agreement, which has been received and considered by Farwell in
     compliance with the applicable terms of the Merger Agreement, provided that
     Farwell has notified Farmers at least five business days in advance of any
     such action and given Farmers the opportunity during such period, if
     Farmers elects in its sole discretion, to negotiate amendments to the
     Merger Agreement which would permit Farwell to proceed with the proposed
     merger with Farmers.

FEES AND EXPENSES

Each party will each pay its own costs and expenses in connection with the
Merger Agreement and the transactions contemplated thereby; provided, however,
if the merger is not consummated due to the failure to obtain any necessary
regulatory approval, Farmers shall reimburse Farwell for its actual costs and
expenses incurred by Farwell after March 9, 2006 in connection with the Merger
Agreement and the transactions contemplated thereby.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

The following discussion addresses the material United States federal income tax
consequences of the merger to holders of Farwell common stock. This discussion
applies only to Farwell shareholders who hold their Farwell common stock as a
capital asset within the meaning of Section 1221 of the Internal Revenue Code.
Further, this discussion does not address all aspects of United States federal
income taxation that may be relevant to a particular shareholder in light of his
or her personal circumstances or to shareholders subject to special treatment
under the United States federal income tax laws, including: banks or trusts;
tax-exempt organizations; insurance companies; regulated investment companies or
mutual funds; dealers in securities or foreign currency; traders in securities
who elect to apply a mark-to-market method of accounting; pass-through entities
and investors in such entities; foreign persons; and shareholders who hold
Farwell common stock as part of a hedge, straddle, constructive sale, conversion
transaction or other integrated instrument; and shareholders of Farwell common
stock who acquired their shares of Farwell common stock upon the exercise of
warrants or employee stock options or otherwise as compensation.

This discussion is based on the Internal Revenue Code, Treasury regulations,
administrative rulings and judicial decisions, all as currently applicable, and
all of which are subject to change (possibly with retroactive effect) and to
differing interpretations. Tax considerations under state, local and foreign
laws are not addressed in this document. Tax consequences to you may vary
depending upon your particular circumstances. Therefore, you should consult your
tax advisor to determine the particular tax consequences of the merger to you,
including those relating to state and/or local taxes.

No ruling has been, or will be, sought from the Internal Revenue Service
concerning tax issues with respect to the merger. It is a condition to the
obligations of Farmers and Farwell to complete the merger that they receive from
Foster, Swift, Collins & Smith, P.C., legal counsel for Farmers and IBT, an
opinion regarding the material federal income tax consequences of the merger
which concludes that the tax consequences of the merger will be substantially
identical to those described in this proxy statement-prospectus.

Based on representations contained in letters provided by IBT and Farwell and on
certain customary factual assumptions, all of which must continue to be true and
accurate in all material respects as of the effective time of the merger, it is
the opinion of Foster, Swift, Collins & Smith, P.C., counsel to Farmers and IBT,
that the material United States federal income tax consequences of the merger
are expected to be as follows:


                                       32


-    the merger will qualify as a "reorganization" within the meaning of Section
     368(a) of the Internal Revenue Code and Farmers, Farwell and IBT will each
     be a "party to a reorganization" within the meaning of Section 368(b);

-    no gain or loss will be recognized by IBT, its subsidiaries or Farwell by
     reason of the merger; and

-    the tax consequences to Farwell shareholders will be as described in detail
     below.

The tax opinion neither binds nor precludes the Internal Revenue Service from
adopting a contrary position. An opinion has no binding effect or official
status of any kind and no assurance can be given that contrary positions will
not be successfully asserted by the Internal Revenue Service or adopted by a
court if the issues are litigated. Accordingly, you are strongly urged to
consult with your tax advisor to determine the particular United States federal,
state, local or foreign income or other tax consequences of the merger to you.

EXCHANGE FOR CASH AND IBT COMMON STOCK

As a result of receiving a combination of cash and IBT common stock in exchange
for shares of Farwell common stock, a Farwell shareholder will recognize gain,
but not loss, equal to the lesser of (1) the amount of cash received or (2) the
amount of gain "realized" in the merger. The amount of gain a Farwell
shareholder "realizes" will equal the amount by which (a) the cash plus the fair
market value at the effective time of the merger of the IBT common stock
received exceeds (b) the shareholder's tax basis in Farwell common stock
surrendered in the merger. If a shareholder of Farwell common stock purchased
his or her shares of Farwell common stock at different prices, such Farwell
shareholder will have to compute his or her recognized gain or loss separately
for the shares of Farwell common stock with different adjusted basis in
accordance with the rules described in the previous sentence. Any recognized
gain would be taxed as a capital gain or a dividend, as described below. The tax
basis of the IBT common stock received in the merger will be the same as the tax
basis of the shares of Farwell common stock surrendered in the merger decreased
by the amount of cash received in the merger and increased by the (i) gain
recognized in the merger, if any and (ii) dividend income recognized in the
merger, if any. The holding period for shares of IBT common stock received by a
Farwell shareholder will include such shareholder's holding period for the
Farwell common stock surrendered in exchange for the IBT common stock, provided
that such shares of Farwell common stock were held as capital assets of the
shareholder at the effective time of the merger.

In certain circumstances, a Farwell shareholder may receive dividend or ordinary
income treatment, rather than capital gain treatment on all or a portion of the
gain recognized in the merger if receipt of the cash portion of the merger
consideration has the effect of the distribution of a dividend under the
principles of Section 302 of the Internal Revenue Code. The determination of
whether a cash payment has such effect is based on a comparison of the Farwell
shareholder's proportionate interest in IBT after the merger with the
proportionate interest the Farwell shareholder would have had if the shareholder
had received solely IBT common stock in the merger. For purposes of this
comparison, the Farwell shareholder may constructively own shares of IBT held by
certain members of the Farwell shareholder's family or certain entities in which
the Farwell shareholder has an ownership or beneficial interest and certain
stock options may be aggregated with the Farwell shareholder's shares of IBT
common stock. The amount of the cash payment that may be treated as a dividend
is limited to the shareholder's ratable share of the accumulated earnings and
profits of Farwell at the effective time of the merger. Any gain that is not
treated as a dividend will be taxed as a capital gain, provided that the Farwell
shareholder's common stock was held as a capital asset at the time of the
merger. Capital gain or loss recognized by a Farwell shareholder in the merger
will be long-term capital gain or loss if the holding period of the shares of
Farwell common stock exceeds one year at the completion of the merger. In the
case of individuals, the maximum federal income tax rate applicable to long-term
capital gains generally is 15%. If a Farwell shareholder has to recognize
ordinary income, such income for individuals is currently taxed at the maximum
rate of 15% if treated as dividend or 35% if treated as other ordinary income.
The determination of whether a cash payment will be treated as having the effect
of a dividend depends primarily upon the facts and circumstances of each Farwell
shareholder. Farwell shareholders are urged to consult their own tax advisors
regarding the tax treatment of the cash received in the merger.

A Farwell shareholder who holds Farwell common stock as a capital asset and who
receives in the merger, in exchange for such stock, cash in lieu of a fractional
share interest in IBT common stock, will be treated as having received such cash
in full payment for such fractional share of stock and as capital gain or loss,
notwithstanding the dividend rules discussed above.

Unless an exemption applies under the backup withholding rules of Section 3406
of the Internal Revenue Code, the Exchange Agent is required to withhold, and
will withhold, 28% of any cash payments to which a Farwell shareholder is
entitled pursuant to the merger, unless the Farwell shareholder provides the
appropriate form. A Farwell shareholder should complete and sign the substitute
Internal Revenue Service Form W-9 enclosed with the letter of transmittal sent
by Isabella Bank and Trust. This completed form provides the information,
including the Farwell shareholder's taxpayer identification number (a social
security number for individuals), and certification necessary to avoid backup
withholding.


                                       33


The foregoing is a summary discussion of material federal income tax
consequences of the merger. The discussion is included for general information
purposes only and may not apply to a particular Farwell shareholder in light of
such shareholder's particular circumstances. Farwell shareholders should consult
their own tax advisors as to the particular tax consequences to them of the
merger, including the application of state, local and foreign tax laws and
possible future changes in federal income tax laws and the interpretation
thereof, which can have retroactive effects.

DISSENTING SHAREHOLDERS. Holders of Farwell common stock who dissent with
respect to the merger as discussed in "Dissenters' Rights" and who receive cash
in respect of their shares of Farwell common stock will recognize capital gain
or loss equal to the difference between the amount of cash received and their
aggregate tax basis in their shares.

HOLDING IBT COMMON STOCK. The following discussion describes the U.S. federal
income tax consequences to a holder of IBT common stock after the merger. Any
cash distribution paid by IBT out of earnings and profits, as determined under
U.S. federal income tax law, will be subject to tax as ordinary dividend income
and will be includible in your gross income in accordance with your method of
accounting. See below under "Tax Rate Changes" for information regarding the
rate of tax on dividends. Cash distributions paid by IBT in excess of its
earnings and profits will be treated as (i) a tax-free return of capital to the
extent of your adjusted basis in your IBT common stock (reducing such adjusted
basis, but not below zero), and (ii) thereafter as gain from the sale or
exchange of a capital asset.

Upon the sale, exchange or other disposition of IBT common stock, you will
generally recognize gain or loss equal to the difference between the amount
realized upon the disposition and your adjusted tax basis in the shares of IBT
common stock surrendered. Any such gain or loss generally will be long-term
capital gain or loss if your holding period with respect to the IBT common stock
surrendered is more than one year at the time of the disposition. For the rate
of tax on capital gains, see below under "Tax Rate Changes."

TAX RATE CHANGES. Under the Jobs and Growth Tax Relief Reconciliation Act of
2003, the individual tax rates on long-term capital gains and dividend income
have been reduced. The top individual rate for long-term capital gains from
sales or exchanges on or after May 6, 2003 is 15%. The top individual rate for
"qualified dividend income" received after December 31, 2002 is also 15%. To be
considered "qualified dividend income" to a particular holder, the holder must
have held the common stock for more than 60 days during the 120 day period
beginning 60 days before the ex-dividend period as measured under section 246(a)
of the Internal Revenue Code. Dividend income that is not qualified dividend
income will be taxed at ordinary income rates. You are urged to consult your tax
advisor to determine whether a dividend, if any, would be treated as qualified
dividend income.

LIMITATIONS ON TAX OPINION AND DISCUSSION. As noted earlier, the tax opinion is
subject to certain assumptions, relating to, among other things, the truth and
accuracy of certain representations made by IBT and Farwell, and the
consummation of the merger in accordance with the terms of the Merger Agreement
and applicable state law. Furthermore, the tax opinion will not bind the
Internal Revenue Service and, therefore, the IRS is not precluded from asserting
a contrary position. The tax opinion and this discussion are based on currently
existing provisions of the Internal Revenue Code, existing and proposed Treasury
regulations, and current administrative rulings and court decisions. There can
be no assurance that future legislative, judicial, or administrative changes or
interpretations will not adversely affect the accuracy of the tax opinion or of
the statements and conclusions set forth herein. Any such changes or
interpretations could be applied retroactively and could affect the tax
consequences of the merger.

THE PRECEDING DISCUSSION IS INTENDED ONLY AS A SUMMARY OF MATERIAL UNITED STATES
FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER. IT IS NOT A COMPLETE ANALYSIS OR
DISCUSSION OF ALL POTENTIAL TAX EFFECTS THAT MAY BE IMPORTANT TO YOU. THUS, WE
URGE FARWELL SHAREHOLDERS TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC
TAX CONSEQUENCES TO THEM RESULTING FROM THE MERGER, INCLUDING TAX RETURN
REPORTING REQUIREMENTS, THE APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL,
AND OTHER APPLICABLE TAX LAWS AND THE EFFECT OF ANY PROPOSED CHANGES IN THE TAX
LAWS.

RESALE OF IBT COMMON STOCK

All shares of IBT common stock received by Farwell shareholders in the merger
will be registered under the Securities Act of 1933 and will be freely
transferable under the Securities Act of 1933, except that shares of IBT common
stock received by persons who are deemed to be "affiliates," as the term is
defined under the Securities Act of 1933, of IBT or Farwell at the time of the
special meeting may be resold by them only in transactions permitted by the
resale provisions of Rule 145 under the Securities Act of 1933 or as otherwise
permitted under the Securities Act of 1933. Persons who may be deemed to be
affiliates of IBT or Farwell generally include individuals or entities that
control, are controlled by, or are under common control with, the party and may
include certain officers and directors of such party as well as principal
shareholders of such party. Affiliates of both parties have previously been
notified of their status. The Merger Agreement requires Farwell to use
reasonable efforts to receive an affiliate letter from each person who is an
affiliate of Farwell.

This proxy statement-prospectus does not cover resales of IBT common stock
received by any person who may be deemed to be an affiliate of Farwell or IBT.


                                       34


ACCOUNTING TREATMENT

In accordance with accounting principles generally accepted in the United States
of America, the merger will be accounted for using the purchase method. As a
result, the recorded assets and liabilities of IBT will be carried forward at
their recorded amounts, the historical operating results will be unchanged for
the prior periods being reported on and the assets and liabilities from the
acquisition of Farwell will be adjusted to fair value at the date of the merger.
In addition, all identified intangibles, which presently consists of a core
deposit intangible, will be recorded at fair value and included as part of the
net assets acquired. To the extent that the purchase price payable to former
Farwell shareholders exceeds the fair value of the net assets including
identifiable intangibles of Farwell at the merger date, that amount will be
reported as goodwill. In accordance with Statement of Financial Accounting
Standards No. 142, "Goodwill and Other Intangible Assets," goodwill will not be
amortized but will be evaluated for impairment annually. Identified intangibles
will be amortized over their estimated lives. Further, the purchase accounting
method results in the operating results of Farwell being included in the
consolidated income of IBT beginning from the date of consummation of the
merger.

DISSENTERS' RIGHTS

Under Michigan banking law, shareholders of Farwell have the right to dissent
from the merger and to receive payment in cash for the fair value of their
shares of Farwell common stock. Farwell shareholders electing to do so must
comply with the provisions of Section 3706(2)(b) of the Michigan Banking Code of
1999 in order to perfect their dissenters' rights. A copy of the applicable
Michigan statute is attached as Appendix D of this document.

ENSURING PERFECTION OF DISSENTERS' RIGHTS CAN BE COMPLICATED. THE PROCEDURAL
RULES ARE SPECIFIC AND MUST BE FOLLOWED PRECISELY. A FARWELL SHAREHOLDER'S
FAILURE TO COMPLY WITH THESE PROCEDURAL RULES MAY RESULT IN HIS OR HER BECOMING
INELIGIBLE TO PURSUE DISSENTERS' RIGHTS.

The following is intended as a brief summary of the material provisions of the
Michigan statutory procedures that a Farwell shareholder must follow in order to
dissent from the merger and obtain payment of the fair value of his or her
shares of Farwell common stock. This summary, however, is not a complete
statement of all applicable requirements and is qualified in its entirety by
reference to Section 3706(2)(b) of the Michigan Banking Code of 1999, the full
text of which appears in Appendix D of this document.

Under Section 3706(2)(b), a shareholder of Farwell who votes against the merger,
or who has given notice in writing to Farwell at or before the meeting called
for the purpose of considering the Merger Agreement that the shareholder
dissents from the merger, is entitled to receive in cash from Farmers the fair
value of all shares held by the shareholder, if and when the merger is
consummated, upon written request made to Farmers at any time within 30 days
after the date of consummation of the merger, accompanied by the surrender of
the stock voted in dissent by the shareholder. Upon the filing of the written
request and the surrender of stock certificates, if any, the shareholder shall
cease to have any of the rights of a shareholder except the right to be paid the
fair value of the shareholder's shares. The request having been made shall not
be withdrawn except with the written consent of Farmers.

The fair value of the shares shall be determined, as of the date on which the
meeting of Farwell shareholders was held adopting the Merger Agreement, by a
qualified and independent appraiser selected by the Commissioner of the Office
of Financial and Insurance Services upon written request submitted by a
dissenting shareholder entitled to receive the fair value of his or her shares.
The appraiser selected shall file a written appraisal with the Commissioner, who
in turn shall forward copies to all interested parties. The valuation determined
by the appraiser is final and binding on all parties as to the fair value of the
shares. Farmers shall pay to each dissenting shareholder entitled the fair value
of his or her shares within 30 days following the receipt of the written
appraisal. The fees and expenses of the appraisal, which shall be approved by
the Commissioner, shall be paid by Farmers.

If you are a Farwell shareholder who elects to exercise dissenters' rights, you
should mail or deliver a written demand to: The Farwell State Savings Bank, 399
West Main Street, Farwell, Michigan, 48622, Attention: Dean L. Beavers,
Corporate Secretary.

IF YOU FAIL TO COMPLY STRICTLY WITH THE PROCEDURES DESCRIBED ABOVE YOU WILL LOSE
YOUR DISSENTERS' RIGHTS. CONSEQUENTLY, IF YOU WISH TO EXERCISE YOUR DISSENTERS'
RIGHTS, WE STRONGLY URGE YOU TO CONSULT A LEGAL ADVISOR BEFORE ATTEMPTING TO
EXERCISE YOUR DISSENTERS' RIGHTS.

                    UNAUDITED PRO FORMA FINANCIAL INFORMATION

The following unaudited pro forma condensed combined balance sheet and income
statement give effect to the merger. This pro forma financial information is
based on the historical consolidated financial statements of IBT and Farwell
under the assumptions, and including the adjustments, set forth in the
accompanying notes to unaudited pro forma condensed combined financial
statements. The unaudited pro forma condensed combined balance sheet presents
combined financial information as of March 31, 2006, and the unaudited pro forma
consolidated condensed combined statement of income presents combined financial
information for the three-month period ended March 31, 2006, and for the year
ended December 31, 2005. The unaudited pro forma consolidated condensed combined
balance sheet assumes the merger was consummated on March 31, 2006, and the
unaudited pro forma condensed combined statements of income give effect to the
merger as if the merger occurred at the beginning of each period covered by such
statements of income. Pro forma per share amounts are based on total merger
consideration of $145 per share of Farwell common stock. The actual amount of
total merger consideration is subject to certain possible adjustments pursuant
to the Merger Agreement.

The unaudited pro forma condensed combined financial statements reflect the
restructuring and other merger related expenses disclosed in the notes to such
statements but do not reflect anticipated cost savings. As a result of this and
other factors, the pro forma combined financial condition and results of
operations of IBT as of and after the effective time of the merger may not be
indicative of the results that actually would have occurred if the merger had
been in effect during the periods presented or of the results that may be
attained in the future.

This pro forma financial information should be read in conjunction with the
historical financial statements of IBT consolidated and Farwell, including the
respective notes to those financial statements that are included or incorporated
by reference in this proxy statement-prospectus, and in conjunction with the pro
forma financial data appearing elsewhere in this proxy statement-prospectus. See

NOTES

(A)

The unaudited pro forma condensed combined balance sheet of IBT Bancorp, Inc.
and subsidiaries and Farwell State Savings Bank at March 31, 2006 has been
prepared as if the merger had been consummated on that date. The unaudited pro
forma condensed combined statements of income for the three-month period ended
March 31, 2006 and for the year ended December 31, 2005 were prepared as if the
merger had been consummated at the beginning of the periods presented. The
unaudited pro forma condensed combined financial statements are based on the
historical financial statements of IBT Bancorp, Inc. and the historical
financial statements of Farwell State Savings Bank and give effect to the merger
under the purchase method of accounting and the assumptions and adjustments in
the notes that follow.

Assumptions relating to the pro forma adjustments set forth in the unaudited pro
forma condensed combined financial statements are summarized as follows:

     (1)  Estimated fair values - The estimated fair value and resulting net
          discount on loans for purposes of these pro forma financial statements

                      FARWELL'S 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 Farwell's financial performance as of the dates and for the periods
indicated. This analysis should be read in conjunction with Farwell's 2005
annual report and other financial information appearing elsewhere in this
document.

The data contained in this management discussion and analysis that are not
historical facts are forward looking statements subject to the safe harbor
created by the Private Securities Litigation Reform Act of 1995. Forward looking
statements, which are based on certain assumptions and describe future plans,
strategies, and expectations of Farwell, are generally identifiable by use of
the words "believe", "intend", "anticipate", "estimate", "project", or similar
expressions. Farwell's ability to predict results or the actual effect of future
plans or strategies is inherently uncertain. Factors which could have an adverse
impact on the operations and future prospects of Farwell include, but are not
limited to, changes in interest rates, general economic conditions, legislation,
regulations, fiscal policy of the United States government, monetary policy of
the Federal Reserve Board, competition from both other financial institutions
and non-financial institutions, and accounting principles. These risks and
uncertainties should be considered in evaluating forward looking statements and
undue reliance should not be placed on such statements.

RESULTS OF OPERATIONS

Net income equaled $1.55 million for the year ended December 31, 2005 compared
to $1.64 million for the same period in 2004, a 5.8% decrease. The decrease in
net income was due primarily to lower net interest income resulting from
increases in interest expense. Return on average assets, which measures the
ability of Farwell to profitably and efficiently employ its resources, equaled
1.69% during 2005 and 1.77% in 2004. Return on average equity, which indicates
how effectively Farwell is able to generate earnings on shareholder invested
capital, equaled 10.84% in 2005 versus 10.29% for the same period in 2004. Net
income for the first quarter of 2006 was $320,000, a $41,000 decrease from the
same period in 2005. Return on assets for the three month period ending March
31, 2006 and 2005 was 1.58%. Return on average equity for the three-month period
ending March 31, 2006 was 9.38% versus 9.54% in 2005. The decrease in net income
was primarily related to a decrease in net interest income and legal and
professional expenses associated with the proposed merger with IBT Bancorp's
wholly owned subsidiary Farmers State Bank of Breckenridge.

NET INTEREST INCOME

Net interest income equals interest income less interest expense and is the
primary source of income for Farwell. 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.

Average assets for the first quarter of 2006 were $90.1 million versus $91.7
million for the year ended December 31, 2005 and $92.7 million for the year
ended December 31, 2004. The $2.6 million decrease since 2004 is primarily
related to payments of special dividends in 2004 and 2005 which has reduced
average shareholders equity by $2.2 million. Since 2004, average loans
outstanding declined $604,000 and investments by $1.6 million. As a result of
the decline in non-interest bearing and relatively low interest bearing funding
sources, and the corresponding decrease in interest earning assets, Farwell's
net interest margin has declined from 4.23% for the year ended December 31, 2004
to 3.97% in the first quarter of 2006. An additional factor adversely affecting
net interest margins is short term interest rates rising more rapidly than long
term rates. Generally, earning assets are repriced based on longer term rates
and funding sources are repriced based on short term interest rates. Thus the
cost of funding has risen disproportionately to the amount earned.

The impact on Farwell's interest income is due to a change in the asset and
liability mix and changes in rates. Management expects short term interest rates
to increase during 2006. Based on this expectation, and assets and liability
re-pricing characteristics, management projects that the fully taxable
equivalent (FTE) net interest margin as a percentage of average assets will
decrease slightly in 2006. Due to the many factors that can affect net interest
income earned, it cannot be predicted with any certainty.

Average assets were $91.7 million during 2005, a $1.0 million decrease since
December 31, 2004. Average loans outstanding increased $924,000 to $64.3
million, investments including federal funds sold decreased $1.7 million, and
other assets decreased $292,000. The decrease in average assets was primarily
due to a $1.7 million decrease in average shareholders' equity resulting from a
payout of excess capital. Deposits increased $550,000 in 2005, of which $347,000
was interest earned by customers being reinvested and a $203,000 increase in
non-interest bearing demand deposits.


                                       47


As shown in Tables 1 and 2, when comparing the twelve month period ending
December 31, 2005 to the same period in 2004, fully taxable interest income
related to the volume of earning assets decreased $16,000. A 0.5% increase in
interest bearing liabilities resulted in $68,000 of additional interest expense.
Overall, changes in volume of assets and liabilities resulted in a reduction of
$84,000 in FTE interest income. The average FTE interest rate earned on assets
increased by 0.11%, increasing FTE interest income by $72,000 and the average
rate paid on deposits increased by 0.34% increasing interest expense by
$162,000. The increased interest rates earned and paid reduced FTE net interest
income by $90,000. Overall FTE net interest income decreased by $174,000 as a
result of changes in volume and rates.

Farwell's FTE net interest yield as a percentage of average earning assets
during 2005 decreased by 0.17% to 4.06%. The decrease is primarily a result of
the average interest rates paid on deposits increasing faster than rates earned
on assets and the decline in non-interest bearing funding from the decline in
capital.

PROVISION FOR LOAN LOSSES

The viability of any financial institution is ultimately determined by its
management of credit risk. Net loans outstanding represent 69% of Farwell's
total assets and is the single largest concentration of risk as of March 31,
2006. 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
non-performing and impaired loans, overall economic conditions, and other
factors. This evaluation is inherently subjective as it requires material
estimates, including the amounts and timing of future cash flows and may be
subject to significant change.

During the first quarter of 2006, Farwell had net charge-offs of $35,000 or
0.21% of loans on an annualized basis. The net loss was entirely related to
consumer loans. Loans classified as substandard declined from 1.23% of gross
loans outstanding as of December 31, 2005 to 1.06% as of March 31, 2006.

As shown in Table 3, net loan charge offs were $44,000 in 2005, a $21,000
increase from 2004. Net charged off loans were 0.07% of average loans in 2005
and 0.04% in 2004. The allowance for loan losses as a percentage of loans
equaled 1.20% and 1.38% as of December 31, 2005 and 2004 respectively.

As shown in Table 4, loans classified as nonperforming plus other real estate
were $793,000 as December 31, 2005, an increase of $201,000 since December 31,
2004. Nonperforming loans as a percentage of outstanding loans were 1.23% and
0.91% as December 31, 2005 and 2004 respectively. During 2005 net charged off
loans were $44,000 and the provision for loans losses was zero. Management did
not


                                       50


provide for any loan losses in 2005 as a result of their internal analysis for
allowance for loan losses showing an adequate amount of allowance for loan
losses. The policy of Farwell is to transfer a loan, including impaired loans,
to non-accrual status whenever it is determined that the interest should be
recorded on a cash basis instead of the accrual basis because of a deterioration
in the financial position of the borrower, it is determined that the payment in
full of principal or interest cannot be expected, or the loan has been in
default for a period of 90 days or more, unless it is both well secured and in
the process of collection. Restructured loans are loans whose terms have been
renegotiated to provide for deferral of interest or principal because of a
borrower's deterioration in their financial position.

The following loans are all the credits which required classification for state
or federal regulatory purposes. Non-performing loans, including other real
estate acquired in satisfaction of loans, were as follows:

As of March 31, 2006, there were no other interest bearing assets which would
require classification. Management is not aware of any recommendations by
regulatory agencies which, if implemented, would have a significant impact on
liquidity, capital, or operations.

In management's opinion, the allowance for loan losses is adequate as of
December 31, 2005. Management has allocated, as shown in Table 5, the allowance
for loan losses to the following categories: commercial and agricultural, 7.7%;
real estate mortgages, 15.9%; installment loans, 68.1%; and unallocated, 8.3%.

TABLE 5. FARWELL ALLOCATION ON THE ALLOWANCE FOR LOAN LOSSES
(DOLLARS IN THOUSANDS)

The allowance for loan losses has been allocated according to the amount deemed
to be reasonably necessary to provide for the possibility of losses being
incurred within the following categories:

NON-INTEREST INCOME AND EXPENSE

Noninterest income consists of deposit service charges and fees for other
financial services. Total income earned from these sources increased $7,000 in
the first quarter of 2006 versus the same period in 2005 and $3,000 during the
year ended December 31, 2005 when compared to the year ended December 31, 2004.
There were no significant changes in any one category during these periods.

Total noninterest expense for the first quarter of 2006 increased $61,000 or
15.7%, when compared to the same period in 2005. The majority of the increase in
2006 is related to an increase in audit and accounting fees as the result of
having a financial statement audit in 2005 versus a compilation in prior years
and legal and other professional expenses related to the proposed merger with
Farmers.

Total non-interest expense for the year ended December 31, 2005 increased
$41,000 or 2.6%. Salary and benefits increased $23,000, equipment and occupancy
expense decreased $13,000 and all other expenses increased $31,000. The largest
component of non-interest expense is salaries and employee benefits. The $23,000
increase is related to normal merit salary increases and increased benefit
costs. Occupancy and equipment expenses decreased $13,000. The decrease is
associated with a decrease in depreciation of equipment and building repairs.
Other non-interest expenses increased $31,000 or 5.8%. The most significant
changes were increases in legal and professional expenses related to the
proposed merger with Farmers.

FEDERAL INCOME TAXES

Federal income tax expense in 2005 was $621,000 or 28.6% of pretax income and in
2004 $732,000 or 30.8% of pre-tax income. The difference between the statutory
rate of 34% and actual rates paid is primarily due to the exclusion of interest
income earned on tax exempt municipal bonds from taxable income.

ANALYSIS OF CHANGES IN FINANCIAL CONDITION

When comparing 2005 year ending balances to 2004, total assets increased $91,000
to $89.1 million. During this period, loans outstanding decreased $414,000,
while fed funds sold and investment securities increased $651,000. Changes in
funding sources include a $1.1 million increase in non-interest bearing
deposits, a $393,000 increase in interest bearing deposits, and a $1.4 million
decrease in shareholders' equity.

INVESTMENT SECURITIES

The primary objective of investing activities is to provide for safety of the
principal invested. Secondary considerations include the need for earnings and
liquidity. During 2005, Farwell's net holdings of investment securities
decreased $471,000. Table 6 shows the carrying value of investment securities
available for sale. At December 31, 2005, Farwell held no securities of any
single issue that exceeded 10% of shareholders' equity.

LOANS

Loans are the largest component of earning assets. As a percentage of assets,
gross loans outstanding were $72.1% as of December 31, 2005. The proper
management of credit risk and market risk is critical to the financial well
being of Farwell. To control these risks, Farwell has adopted strict
underwriting standards. The standards include limits against lending outside
Farwell's defined market area, lending limits to a single borrower, and loan to
collateral value limits. Farwell has no foreign loans, and there were no
concentrations greater than 10% of total loans that are not disclosed as a
separate category in Table 8.

TABLE 8. FARWELL LOAN PORTFOLIO
(DOLLARS IN THOUSANDS)

As shown in the following table, total loans decreased $458,000 in 2005 to $64.2
million. The decrease was primarily in residential real estate and personal loan
categories.

Table 10, average deposits increased $550,000 in 2005 or 0.7%. Within the
banking industry there is agreement that competition from equity investments,
the bond market, and other financial intermediaries has had a significant impact
on deposit growth. The result of this competition is a general slowing of
deposit growth. To fund asset growth in the future, it is likely that Farwell is
going to have to obtain funds from other sources such as the Federal Home Loan
Bank.

CAPITAL

The capital of Farwell consists solely of common stock, capital surplus,
retained earnings, and accumulated other comprehensive income. Total capital
decreased $1.4 million in 2005. The decrease was related to the payment of $2.9
million cash dividend in 2005.

The Federal Reserve Board's current recommended minimum primary capital to
assets requirement is 6.0%. Farwell's primary capital to assets, which consists
of shareholders' equity plus allowance for loan losses was 15.9% as of December
31, 2005.

The Federal Reserve has also established minimum capital requirements for banks.
Table 12 shows the minimum regulatory capital requirement to be considered well
capitalized and Farwell's ratios. Tier 1 capital consists of shareholders'
equity, excluding unrealized gains and losses on securities available for sale
less intangible assets. Total capital is comprised of Tier 1 capital plus the
allowance for loan losses. At March 31, 2006, Farwell continued to be well
capitalized under the prompt corrective action regulatory criteria, as shown
below.

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 the payment
of cash dividends. The primary sources of Farwell's liquidity are cash, cash
equivalents, and investment securities available for sale.

As of March 31, 2006, cash and cash equivalents as a percentage of total assets
equaled 7.9% versus 5.6% as of December 31, 2005. During the first three months
of 2006, $152,000 in net cash was provided from operations. Investing activities
used $135,000 and financing activities resulted in a $2.3 million increase in
cash and cash equivalents. Overall, cash and cash equivalents increased $2.3
million in the first quarter of 2006. In addition to funding from traditional
sources Farwell has the ability to borrow in the federal funds market. Farwell's
liquidity is considered adequate by management.

ASSET AND LIABILITY MANAGEMENT

Asset and liability management aims at achieving reasonable stability in the net
interest margins through periods of changing interest rates. One method to
measure the exposure to changes in interest rates is gap analysis. GAP analysis
measure the cash flows and/or the earliest repricing of Farwell's interest
bearing assets and liabilities. The analysis is useful for measuring trends in
the repricing characteristics of the balance sheet. As shown in Table 13, the
gap analysis depicts Farwell's position for specific time periods and the
cumulative gap as a percentage of total assets.

Investment securities and other investments are scheduled according to their
contractual maturity. Nonvariable rate loans are included in the appropriate
time frame based on their scheduled amortization. Farwell does not offer
variable rate loans. Time deposits are scheduled according to their contractual
maturity. Money market, NOW, and savings accounts have no contractual maturity
and are believed to be predominantly noninterest sensitive by management. For
purposes of gap analysis, these deposits are included in the 0-3 month repricing
time frame.

Farwell has no foreign exchange risk, holds no trading account assets, nor does
it utilize interest rate swaps or derivatives in the management of its interest
rate risk. Farwell does have a significant portion of its assets in real estate
mortgages.

(DOLLARS IN THOUSANDS)

The following table shows the time periods and the amount of assets and
liabilities available for interest rate repricing as of December 31, 2005. For
purposes of this analysis, nonaccrual loans and the allowance for loan losses
are excluded.

IMPACT OF INFLATION

The majority of assets and liabilities of financial institutions are monetary in
nature. Generally, changes in interest rates have a more significant impact on
earnings of Farwell than inflation. Although influenced by inflation, changes in
rates do not necessarily move in either the same magnitude or direction as
changes in the price of goods and services. Inflation does impact the growth of
total assets, creating a need to increase equity capital at a higher rate to
maintain an adequate equity to assets ratio, which in turn reduces the amount of
earnings available for cash dividends.

Stockholders and Board of Directors
The Farwell State Savings Bank
Farwell, Michigan

We have audited the accompanying balance sheet of THE FARWELL STATE SAVINGS BANK
as of December 31, 2005, and the related statements of income, comprehensive
income, changes in stockholders' equity and cash flows for the year then ended.

Our responsibility is to express an opinion on these financial statements based
on our audit.

We conducted our audit of the 2005 financial statements in accordance with
auditing standards generally accepted in the United States of America. Those
standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the 2005 financial statements referred to above present fairly,
in all material respects, the financial position of THE FARWELL STATE SAVINGS
BANK as of December 31, 2005, and the results of its operations and its cash
flows for the year then ended in conformity with accounting principles generally
accepted in the United States of America.

1.   BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     BUSINESS AND CONCENTRATIONS OF RISK

     THE FARWELL STATE SAVINGS BANK ("Farwell") provides a variety of financial
     services to individuals and businesses in Mid-Michigan through its two
     locations in Farwell and Lake, Michigan. Active competition, principally
     from other commercial banks, savings banks and credit unions, exists in all
     of Farwell's primary markets. Farwell's results of operations can be
     significantly affected by changes in interest rates or changes in the
     tourism industry which comprise a significant portion of the local economic
     environment.

     Farwell's primary deposit products are interest and noninterest bearing
     checking accounts, savings accounts and time deposits and its primary
     lending products are real estate mortgages, commercial and consumer loans.
     Note 3 further describes the types of lending Farwell engages in and Note 6
     provides additional information on deposits. Note 2 discusses the types of
     securities Farwell invests in. Farwell does not have significant
     concentrations with respect to any one industry, customer, or depositor.

     Farwell is a state chartered bank and is a member of the Federal Deposit
     Insurance Corporation ("FDIC") Bank Insurance Fund. Farwell is subject to
     the regulations and supervision of the FDIC and state regulators and
     undergoes periodic examinations by these regulatory authorities.

     USE OF ESTIMATES

     In preparing financial statements in conformity with generally accepted
     accounting principles, management is required to make estimates and
     assumptions that affect the reported amounts of assets and liabilities as
     of the date of the balance sheet and the reported amounts of revenues and
     expenses during the year. Actual results could differ from those estimates.
     The material estimate that is particularly susceptible to significant
     change in the near term relates to the determination of the allowance for
     loan losses.

     ACCOUNTING POLICIES

     Accounting policies used in preparation of the accompanying financial
     statements conform to predominant banking industry practices and are based
     on generally accepted accounting principles. The principles which
     materially affect the determination of the financial position or results of
     operations of Farwell are summarized below:

          CASH AND CASH EQUIVALENTS

          For the purposes of the statements of cash flows, cash and cash
          equivalents include cash on hand, amounts due from banks, and federal
          funds sold. Generally, federal funds are sold for a one-day period.
          Farwell maintains deposit accounts in various financial institutions
          which generally exceed federally insured limits or are not insured.

          SECURITIES

          Securities are classified as "available-for-sale" and are recorded at
          fair value with unrealized gains and


                                       64


                         THE FARWELL STATE SAVINGS BANK

                          NOTES TO FINANCIAL STATEMENTS
                             (DOLLARS IN THOUSANDS)

          losses, net of the effect of deferred income taxes, excluded from
          earnings and reported in other comprehensive income.

          Purchase premiums and discounts are recognized in interest income
          using the interest method over the terms of the securities. Declines
          in the fair value of available-for-sale securities below their cost
          that are deemed to be other than temporary are reflected in earnings
          as realized losses. In estimating other-than-temporary impairment
          losses, management considers 1) the length of time and extent to which
          the fair value has been less than cost, 2) the financial condition and
          near-term prospects of the issuer, and 3) the intent and ability of
          Farwell to retain its investment in the issuer for a period of time
          sufficient to allow for anticipated recovery in fair value. Gains or
          losses on the sale of securities are recorded on the trade date and
          are determined using the specific identification method.

          LOANS

          Loans that management has the intent and ability to hold for the
          foreseeable future or until maturity or pay-off are generally reported
          at their outstanding unpaid principal balances adjusted for
          charge-offs, the allowance for loan losses, and any deferred fees or
          costs on originated loans. Interest income is accrued on the unpaid
          principal balance. Management estimates that direct costs incurred in
          originating loans classified as held-to-maturity approximate the
          origination fees generated on these loans. Therefore, net deferred
          loan origination fees on loans classified as held-to-maturity are not
          included on the accompanying balance sheets.

          The accrual of interest on mortgage and commercial loans is
          discontinued at the time the loan is 90 days past due unless the
          credit is well-secured and in process of collection. Personal loans
          are typically charged off no later than 180 days past due. Past due
          status is based on contractual terms of the loan. In all cases, loans
          are placed on non-accrual or charged-off at an earlier date if
          collection of principal and interest is considered doubtful.

          All interest accrued but not collected for loans that are placed on
          non-accrual or charged off is reversed against interest income, while
          interest accrued but not collected for prior years is reversed against
          the allowance for loan losses. The interest on these loans is
          accounted for on the cash-basis or cost-recovery method, until
          qualifying for return to accrual. Loans are returned to accrual status
          when all principal and interest amounts contractually due are brought
          current and future payments are reasonably assured.

          ALLOWANCE FOR LOAN LOSSES

          The allowance for loan losses is established as losses are estimated
          to have occurred through a provision for loan losses charged to
          earnings. Loan losses are charged against the allowance when
          management believes the uncollectibility of the loan balance is
          confirmed. Subsequent recoveries, if any, are credited to the
          allowance.

          The allowance for loan losses is evaluated on a regular basis by
          management and is based upon management's periodic review of the
          collectibility of the loans in light of historical experience, the
          nature and volume of the loan portfolio, adverse situations that may
          affect the borrower's ability to


                                       65


                         THE FARWELL STATE SAVINGS BANK

                          NOTES TO FINANCIAL STATEMENTS
                             (DOLLARS IN THOUSANDS)

          repay, estimated value of any underlying collateral and prevailing
          economic conditions. This evaluation is inherently subjective as it
          requires estimates that are susceptible to significant revision as
          more information becomes available.

          The allowance consists of specific, general and unallocated
          components. The specific component relates to loans that are
          classified as doubtful, substandard or special mention. For such loans
          that are classified as impaired, an allowance is established when the
          discounted cash flows (or collateral value or observable market price)
          of the impaired loan is lower than the carrying value of that loan.
          The general component covers non-classified loans and is based on
          historical loss experience adjusted for qualitative factors. An
          unallocated component is maintained to cover uncertainties that could
          affect management's estimate of probable losses. The unallocated
          component of the allowance reflects the margin of imprecision inherent
          in the underlying assumptions used in the methodologies for estimating
          specific and general losses in the portfolio.

          A loan is considered impaired when, based on current information and
          events, it is probable that Farwell will be unable to collect the
          scheduled payments of principal or interest when due according to the
          contractual terms of the loan agreement. Factors considered by
          management in determining impairment include payment status,
          collateral value, and the probability of collecting scheduled
          principal and interest payments when due. Loans that experience
          insignificant payment delays and payment shortfalls generally are not
          classified as impaired. Management determines the significance of
          payment delays and payment shortfalls on a case-by-case basis, taking
          into consideration all of the circumstance surrounding the loan and
          the borrower, including the length of the delay, the reasons for the
          delay, the borrower's prior payment record, and the amount of the
          shortfall in relation to the principal and interest owed. Impairment
          is measured on a loan by loan basis for commercial and construction
          loans by either the present value of expected future cash flows
          discounted at the loan's effective interest rate, the loan's
          obtainable market price, or the fair value of the collateral if the
          loan is collateral dependent.

          Large groups of smaller balance homogeneous loans are collectively
          evaluated for impairment. Accordingly, Farwell generally does not
          separately identify individual consumer and residential loans for
          impairment disclosures, unless such loans are the subject of a
          restructuring agreement.

          FORECLOSED ASSETS

          Assets acquired through, or in lieu of, loan foreclosure are held for
          sale and are initially recorded at fair value at the date of transfer,
          establishing a new cost basis. Subsequent to foreclosure, valuations
          are periodically performed by management and the assets are carried at
          the lower of the carrying amount or fair value less costs to sell.
          Revenue and expenses from operations and changes in the valuation
          allowance are included in net expenses from foreclosed assets.

          PREMISES AND EQUIPMENT

          Land is carried at cost. Premises and equipment are carried at cost
          less accumulated depreciation. Depreciation is computed principally by
          the straight-line method based upon the useful lives of the related
          assets which generally range from 3 to 40 years. Maintenance, repairs,
          and minor alterations are charged to current operations as
          expenditures occur and major improvements are capitalized.

          CORPORATE OWNED LIFE INSURANCE

          Farwell has purchased life insurance policies on certain key
          executives. Corporate owned life insurance is recorded at its cash
          surrender value, or the amount that can be realized.

          OFF-BALANCE SHEET CREDIT RELATED FINANCIAL INSTRUMENTS

          In the ordinary course of business, Farwell has entered into
          commitments to extend credit, including commercial letters of credit
          and standby letters of credit. Such financial instruments are recorded
          when they are funded.

          FEDERAL INCOME TAXES

          Federal income taxes are provided for the tax effects of transactions
          reported in the financial statements and consist of taxes currently
          due plus deferred income taxes. Deferred income taxes are recognized
          for temporary differences between the carrying amounts of assets and
          liabilities for financial reporting purposes and the amounts used for
          income tax purposes. Deferred income tax assets and liabilities
          represent the future tax return consequences of those differences,
          which will either be taxable or deductible when the assets or
          liabilities are recorded or settled. Valuation allowances are
          established when necessary to reduce deferred tax assets to the amount
          expected to be realized. As changes in income tax laws or rates are
          enacted, deferred tax assets and liabilities are adjusted through the
          provision for income taxes.

          NET INCOME PER SHARE

          Net income per basic share of common stock represents income available
          to common stockholders divided by the weighted-average number of
          common shares outstanding during the year, which was 262,500 in 2005,
          2004, and 2003.

     Management evaluates securities for other-than-temporary impairment at
     least on a quarterly basis, and more frequently when economic or market
     concerns warrant such evaluation. Consideration is given to (1) the length
     of time and the extent to which the fair value has been less than cost, (2)
     the financial condition and near-term prospects of the issuer, and (3) the
     intent and ability of Farwell to retain its investment in the issuer for a
     period of time sufficient to allow for any anticipated recovery in fair
     value.

     At December 31, 2005, 12 government and federal agencies, 33 state and
     municipal, and 3 corporate securities have unrealized losses with aggregate
     depreciation of 1.0%, 1.0% and 1.3%, respectively.

     In analyzing an issuer's financial condition, management considers whether
     the securities are issued by the federal government or its agencies,
     whether downgrades by bond rating agencies have occurred, and industry
     analysts' reports. As Farwell has the ability to hold debt securities until
     maturity, or for the foreseeable future

3.   LOANS

     Farwell grants commercial, consumer and residential mortgage loans to
     customers situated primarily in Mid-Michigan. The ability of Farwell's
     debtors to honor their contracts is dependent upon the real estate and
     general economic conditions in this area. Substantially all of the consumer
     and residential loans are secured by various items of property, while
     commercial loans are secured primarily by business assets and personal
     guarantees; a portion of loans are unsecured.

     Major loan classifications are as follows at December 31:

8.   RETIREMENT PLAN

     Farwell maintains a non-leveraged Employee Stock Ownership Plan (ESOP) with
     a 401(k) provision. Substantially all employees of Farwell are covered
     under the plan. Farwell contributed 15 percent, the maximum allowed under
     the Internal Revenue Code, of employee gross earnings during 2005 and 2004
     and 2003. The cost of the plan amounted to $92, $90, and $86 in 2005, 2004,
     and 2003, respectively. Total shares outstanding related to the ESOP for
     each of the three years ended December 31, 2005 were 26,582 and were
     included in the computation of dividends and earnings per share in each of
     the respective years.

11.  OFF-BALANCE SHEET ACTIVITIES

     CREDIT-RELATED FINANCIAL INSTRUMENTS

     Farwell is a party to credit related 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, standby letters of credit and commercial
     letters of credit. Such commitments involve, to varying degrees, elements
     of credit and interest rate risk in excess of the amount recognized in the
     balance sheets. Farwell's exposure to credit loss is represented by the
     contractual amount of these commitments. Farwell follows the same credit
     policy in making commitments, including collateral, as it does for
     on-balance-sheet instruments; no significant losses are anticipated as a
     result of these commitments.

     At December 31, 2005 and 2004, the following financial instruments were
     outstanding whose contract amounts represent credit risk:



                                             CONTRACT AMOUNT
                                             ---------------

                         THE FARWELL STATE SAVINGS BANK

                          NOTES TO FINANCIAL STATEMENTS
                             (DOLLARS IN THOUSANDS)

     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.
     Commitments generally have fixed expiration dates or other termination
     clauses and may require payment of a fee. The commitments may expire
     without being drawn upon. Therefore, the total commitment amounts do not
     necessarily represent future cash requirements. The amount of collateral
     obtained, if it is deemed necessary by Farwell, is based on management's
     credit evaluation of the customer.

     Unfunded commitments under commercial lines-of-credit, revolving credit
     lines, equity lines-of-credit, and overdraft protection agreements are
     commitments for possible future extensions of credit to existing customers.
     These lines-of-credit are uncollateralized and usually do not contain a
     specified maturity date and may not be drawn upon to the total extent to
     which Farwell is committed.

     Commercial and standby letters-of-credit are conditional commitments issued
     by Farwell to guarantee the performance of a customer to a third party.
     Those letters-of-credit are primarily issued to support public and private
     borrowing arrangements. Essentially all letters-of-credit issued have
     expiration dates within one year. The credit risk involved in issuing
     letters-of-credit is essentially the same as that involved in extending
     loan facilities to customers. Farwell generally holds collateral supporting
     those commitments if deemed necessary.

12.  REGULATORY REQUIREMENTS

     CAPITAL REQUIREMENTS

     Farwell is subject to various regulatory capital requirements administered
     by the federal banking agencies. Failure to meet minimum capital
     requirements can initiate certain mandatory and possibly additional
     discretionary actions by regulators, that if undertaken, could have a
     direct material effect on Farwell's financial statements. Under capital
     adequacy guidelines and the regulatory framework for prompt corrective
     action, Farwell must meet specific capital guidelines that involve
     quantitative measures of their assets, liabilities, capital and certain
     off-balance-sheet items as defined in the regulations and calculated under
     regulatory accounting practices. The capital amounts and classification are
     also subject to qualitative judgments by the regulators about components,
     risk weightings and other factors.

     Quantitative measurements established by regulation to ensure capital
     adequacy require Farwell to maintain minimum amounts and ratios (set forth
     in the following table) of total and Tier 1 capital (as defined in the
     regulations) to risk-weighted asset (as defined) and Tier 1 capital to
     average assets (as defined). Management believes, as of December 31, 2005
     and 2004, that Farwell met all capital adequacy requirements to which it is
     subject.

     As of December 31, 2005, the most recent notification from the Federal
     Deposit Insurance Corporation categorized Farwell as well capitalized under
     the regulatory framework for prompt corrective action. To be categorized as
     well capitalized, an institution must maintain minimum total risk-based,
     Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the following
     tables. There are no conditions or events since the notification that
     management believes have changed Farwell's category. Farwell's actual
     capital amounts and ratios as of December 31, 2005 and 2004 are also
     presented in the table.

13.  CONTINGENCIES

     LITIGATION

     Farwell is party to litigation arising during the normal course of
     business. In the opinion of management, based on consultation with legal
     counsel, the resolution of such litigation is not expected to have a
     material effect on the financial statements.

     ENVIRONMENTAL ISSUES

     As a result of acquiring real estate from foreclosure proceedings, Farwell
     is subject to potential claims and possible legal proceedings involving
     environmental matters. No such claims have been asserted as of December 31,
     2005.

14.  SUBSEQUENT EVENT

     On December 22, 2005, The Farwell State Savings Bank signed a definitive
     agreement to be acquired by IBT Bancorp, Inc. (the "Agreement"). The
     Agreement was amended and restated effective May 2, 2006 to provide for the
     merger of Farwell with and into Farmers State Bank of Breckenridge, a
     wholly-owned subsidiary of IBT Bancorp, Inc. The acquisition is subject to
     regulatory approval.

                           FORWARD-LOOKING STATEMENTS

This document, including information included or incorporated by reference in
this document may contain forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. These forward-looking
statements include, but are not limited to:

(i) the  financial  condition,  results of  operations  and  business of IBT and
Farwell;

(ii) statements about the benefits of the merger, including future financial and
operating  results,  cost  savings,  enhancements  to revenue and  accretion  to
reported earnings that may be realized from the merger;

(iii)  statements  about our  respective  plans,  objectives,  expectations  and
intentions and other statements that are not historical facts; and

(iv) other  statements  identified  by words such as  "expects,"  "anticipates,"
"intends,"  "plans,"  "believes,"  "seeks,"  "estimates,"  or words  of  similar
meaning.  These  forward-looking  statements  are based on current  beliefs  and
expectations  of our  management  and  are  inherently  subject  to  significant
business,  economic and competitive  uncertainties  and  contingencies,  many of
which are beyond our control. In addition, these forward-looking  statements are
subject to assumptions with respect to future business  strategies and decisions
that are subject to change.  The following  factors,  among others,  could cause
actual results to differ materially from the anticipated results or other


                                       83


expectations expressed in the forward-looking statements:

-    general economic conditions in the areas in which we operate;

-    our businesses may not be combined successfully, or such combination may
     take longer to accomplish than expected;

-    delays or difficulties in the integration by IBT of recently acquired
     businesses;

-    the growth opportunities and cost savings from the merger may not be fully
     realized or may take longer to realize than expected;

-    operating costs, customer losses and business disruption following the
     merger, including adverse effects of relationships with employees, may be
     greater than expected;

-    governmental approvals of the merger may not be obtained, or adverse
     regulatory conditions may be imposed in connection with governmental
     approvals of the merger;

-    adverse governmental or regulatory policies may be enacted;

-    the interest rate environment may change, causing margins to compress and
     adversely affecting net interest income;

-    the risks associated with continued diversification of assets and adverse
     changes to credit quality;

-    competition from other financial services companies in our markets;

-    the concentration of IBT's operations in Michigan may adversely affect
     results if the Michigan economy or real estate market declines; and

-    the risk of an economic slowdown that would adversely affect credit quality
     and loan originations.

Additional factors that could cause actual results to differ materially from
those expressed in the forward-looking statements are discussed in IBT's reports
filed with the Securities and Exchange Commission.

All subsequent written and oral forward-looking statements concerning the
proposed transaction or other matters attributable to either of us or any person
acting on our behalf are expressly qualified in their entirety by the cautionary
statements above. Neither of us undertake any obligation to update any
forward-looking statement to reflect circumstances or events that occur after
the date the forward-looking statements are made.

that (i) there are no adverse Federal or state income tax consequences to FSSB
shareholders as a result of the modification; (ii) the consideration to be paid
to the holders of FSSB Common Stock under this Agreement is not thereby changed

such modification will not delay materially or jeopardize receipt of any
required Regulatory Approvals or other consents and approvals relating to the
consummation of the Merger. The parties hereto agree to appropriately amend this
Agreement and any related documents in order to reflect any such revised

Effective Time, by virtue of the Merger and without any action on the part of
Farmers, FSSB or the holders of any of the shares of FSSB Common Stock, the
Merger shall be effected in accordance with the following terms:

          (a) Each share of Farmers Common Stock that is issued and outstanding
immediately prior to the Effective Time shall remain issued and outstanding
following the Effective Time and shall be unchanged by the Merger.

          (b) All shares of FSSB Common Stock held in the treasury of FSSB and
each share of FSSB Common Stock owned by IBT or any direct or indirect wholly
owned subsidiary of IBT or of FSSB immediately prior to the Effective Time,
shall cease to exist, and the certificates for such shares shall be canceled as
promptly as practicable thereafter, and no payment or distribution shall be made
in consideration therefor.


                                      A-10



          (c) Except as set forth above, each share of FSSB Common Stock issued
and outstanding immediately prior to the Effective Time (other than Dissenting
Shares) shall become and be converted into, as provided in and subject to the
limitations set forth in this Agreement, the right to receive shares of IBT
Common Stock and cash based on the Exchange Ratio (the "Merger Consideration").

          (d) Each outstanding share of FSSB Common Stock the holder of which
has perfected his right to dissent under Michigan Banking Law and has not
effectively withdrawn or lost such right as of the Effective Time (the
"Dissenting Shares") shall not be converted into or represent a right to receive
the Merger Consideration hereunder, and the holder thereof shall be entitled
only to such rights as are granted by Michigan Banking Law. FSSB shall give
Farmers prompt notice upon receipt by FSSB of any such demand for payment of the
fair value of such shares of FSSB Common Stock and of withdrawals of such
demands and any other instruments provided pursuant to applicable law (any
shareholder duly making such demand being hereinafter called a "Dissenting
Shareholder"), and Farmers shall have the right to participate in all
negotiations and proceedings with respect to any such demand for payment, or
waive any failure to timely deliver a written demand for appraisal or the taking
of any other action by such Dissenting Shareholder as may be necessary to
perfect appraisal rights under Michigan Banking Law. Any payments made with
respect to Dissenting Shares shall be made by the Surviving Corporation.

          (e) If any Dissenting Shareholder shall effectively withdraw or lose
(through failure to perfect or otherwise) his right to payment as a Dissenting
Shareholder at or prior to the Effective Time, such holder's shares of FSSB
Common Stock shall be converted into a right to receive the Merger Consideration
in accordance with the applicable provisions of this Agreement.

          (f) At the Effective Time, shares of FSSB Common Stock shall
automatically be canceled and shall no longer be outstanding, and shall be
converted into the right to receive the Merger Consideration.

          (g) Notwithstanding anything to the contrary contained herein, no
certificates or script representing fractional shares of IBT Common Stock shall
be issued upon the surrender and exchange of Certificates, no dividend or
distribution with respect to IBT Common Stock shall be payable on or with
respect to any fractional share interest, and such fractional share interests
shall not entitle the owner thereof to vote or to any other rights of a
shareholder of IBT. In lieu of the issuance of any such fractional share,
Farmers shall pay to each former holder of FSSB Common Stock who otherwise would
be entitled to receive a fractional share of IBT Common Stock, an amount in
cash, rounded to the nearest cent and without interest, equal to the product of
(i) the fraction of a share to which such holder would otherwise have been
entitled and (ii) $42.00. For purposes of determining any fractional share
interest, all shares of FSSB Common Stock owned by a FSSB shareholder shall be
combined so as to calculate the maximum number of whole shares of IBT Common
Stock issuable to such FSSB Shareholder.

          (h) In the event that, subsequent to the date of this Agreement but
prior to the Effective Time, the outstanding shares of IBT Common Stock and/or
FSSB Common Stock shall


                                      A-11



have been increased, decreased, changed into or exchanged for a different number
or kind of shares or securities through a reorganization, recapitalization,
reclassification, stock dividend, stock split, reverse stock split, or other
similar change in capitalization, or exchanged or converted into shares or
securities of another corporation, then an appropriate, equitable and
proportionate adjustment shall be made to the Exchange Ratio.

     3.2. Procedures for Exchange of FSSB Common Stock.

          (a) IBT to Make Merger Consideration Available. No later than the
Closing Date, IBT shall deposit, or shall cause to be deposited, in an account
with the Exchange Agent for the benefit of the holders of FSSB Common Stock, for
exchange in accordance with this Section 3.2, certificates representing the
shares of IBT Common Stock and an aggregate amount of cash sufficient to pay the
aggregate amount of cash payable pursuant to this Article III (such cash and
certificates for shares of IBT Common Stock, together with any dividends or
distributions with respect thereto (without any interest thereon) being
hereinafter referred to as the "Exchange Fund").

          (b) Exchange of Certificates. IBT shall take any steps necessary to
cause the Exchange Agent, within five (5) business days after the Effective
Time, to mail to each holder of a Certificate or Certificates, a form letter of
transmittal for return to the Exchange Agent and instructions for use in
effecting the surrender of the Certificates in exchange for the Merger
Consideration. The letter of transmittal shall be in customary form and shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Exchange
Agent. Upon proper surrender of a Certificate for exchange and cancellation to
the Exchange Agent, together with a properly completed letter of transmittal,
duly executed, the holder of such Certificate shall be entitled to receive in
exchange therefore the Merger Consideration to which such holder of FSSB Common
Stock shall have become entitled pursuant to Section 3.1(c) and 3.1(g) hereof,
and the Certificate so surrendered shall forthwith be cancelled. No interest
will be paid or accrued on any cash payable hereunder or any unpaid dividends
and distributions, if any, payable to holders of Certificates.

          (c) Rights of Certificate Holders After the Effective Time. After the
Effective Time, the holders of the Certificates shall have no rights (excluding
dissenter's rights of those shareholders properly exercising dissenter's rights)
with respect to the shares of FSSB Common Stock formerly represented by those
Certificates except to surrender those Certificates in exchange for the Merger
Consideration as provided in this Agreement. No dividends or other distributions
declared after the Effective Time with respect to IBT Common Stock or interest
with respect to cash that is part of the Exchange Fund shall be paid to the
holder of any Certificate until the holder thereof shall surrender such
Certificate in accordance with this Section 3.2. After the surrender of a
Certificate in accordance with this Section 3.2, the record holder thereof shall
be entitled to receive any dividends or other distributions, without any
interest thereon, that become payable after the Effective Time with respect to
the shares of IBT Common Stock that are part of the Merger Consideration for the
shares of FSSB Common Stock represented by the surrendered Certificate.


                                      A-12


          (d) Surrender by Persons Other than Record Holders. If the Person
surrendering a Certificate and signing the accompanying letter of transmittal is
not the record holder thereof, then it shall be a condition of the payment of
the Merger Consideration that: (i) such Certificate is properly endorsed to such
Person or is accompanied by appropriate stock powers, in either case signed
exactly as the name of the record holder appears on such Certificate, and is
otherwise in proper form for transfer, or is accompanied by appropriate evidence
of the authority of the Person surrendering such Certificate and signing the
letter of transmittal to do so on behalf of the record holder; and (ii) the
person requesting such exchange shall pay to the Exchange Agent in advance any
transfer or other taxes required by reason of the payment to a Person other than
the registered holder of the Certificate surrendered, or required for any other
reason, or shall establish to the satisfaction of the Exchange Agent that such
tax has been paid or is not payable.

          (e) Closing of Transfer Books. From and after the Effective Time,
there shall be no transfers on the stock transfer books of FSSB of the FSSB
Common Stock that were outstanding immediately prior to the Effective Time. If,
after the Effective Time, Certificates representing such shares are presented
for transfer to the Exchange Agent, they shall be exchanged for the Merger
Consideration and canceled as provided in this Section 3.2. Certificates
surrendered for exchange by any person constituting an "Affiliate" of FSSB for
purposes of Rule 145 under the Securities Act shall not be exchanged until
Farmers has received a written agreement from such person as provided in Section
8.4.

          (f) Return of Exchange Fund. At any time following the twelve (12)
month period after the Effective Time, IBT shall be entitled to require the
Exchange Agent to deliver to it any portions of the Exchange Fund which has been
made available to the Exchange Agent and not disbursed to holders of
Certificates (including, without limitation, all interest and other income
received by the Exchange Agent in respect of all funds made available to it),
and thereafter such holders shall be entitled to look to IBT (subject to
abandoned property, escheat and other similar laws) with respect to any Merger
Consideration that may be payable upon due surrender of the Certificates held by
them. Notwithstanding the foregoing, neither IBT nor the Exchange Agent shall be
liable to any holder of a Certificate for any Merger Consideration delivered in
respect of such Certificate to a public official pursuant to any abandoned
property, escheat or other similar law.

          (g) Lost, Stolen or Destroyed Certificates. In the event any
Certificate shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the person claiming such Certificate to be lost,
stolen or destroyed and, if required by IBT, the posting by such person of a
bond in such amount as IBT may reasonably direct as indemnity against any claim
that may be made against it with respect to such Certificate, the Exchange Agent
will issue in exchange for such lost, stolen or destroyed Certificate, the
Merger Consideration deliverable in respect thereof.

               (ii) Each real estate lease that will require the consent of the

Knowledge, neither FSSB nor any FSSB Subsidiary is in default in any material
respect under any material contract, agreement, commitment, arrangement, lease,
insurance policy or other instrument to which it is a party, by which its
assets, business, or operations may be bound or affected, or under which it or

its assets, business, or operations receive benefits, and there has not occurred

constitute such a default.

have been made available to Farmers or its Affiliates on or before the date
hereof, are listed on FSSB Disclosure Schedule 4.1(i)(i) and 4.1(i)(ii) and are
in full force and effect on the date hereof. Except as set forth in FSSB
Disclosure Schedule 4.1(i)(iii), no plan, contract, employment agreement,
termination agreement, or similar agreement or arrangement to which FSSB or any
FSSB Subsidiary is a party or under which FSSB or any FSSB Subsidiary may be
liable contains provisions which permit an employee or independent contractor to
terminate it without cause and continue to accrue future benefits thereunder.
Except as set forth in FSSB Disclosure Schedule 4.1(i)(iii), no such agreement,
plan, contract, or arrangement (x) provides for acceleration in the vesting of

and property reflected in the balance sheet contained in the most recent FSSB
Financial Statements or acquired subsequent thereto (except to the extent that
such assets and properties have been disposed of in the ordinary course of
business, since the date of such balance sheet), subject to no material
encumbrances, liens, mortgages, security interests or pledges, except (i) those
items which secure liabilities for public or statutory obligations or any
discount with, borrowing from or other obligations to FHLB, inter-bank credit

good faith. FSSB and the FSSB Subsidiaries, as lessee, have the right under
valid and existing leases of real and personal properties used by FSSB and the
FSSB Subsidiaries in the conduct of their businesses to occupy or use all such
properties as presently occupied and used by each of them. Such existing leases
and commitments to lease constitute or will constitute operating leases for both
tax and financial accounting purposes and the lease expense and minimum rental
commitments with respect to such leases and lease commitments are as disclosed
in all material respects in the notes to the FSSB Financial Statements.

               (ii) FSSB and each Significant Subsidiary of FSSB currently

premium costs with respect to such policies of insurance will be substantially
increased. There are presently no material claims pending under such policies of
insurance and no notices


                                      A-19

under such policies. All such insurance is valid and enforceable and in full
force and effect, and within the last three (3) years FSSB and each Significant
Subsidiary of FSSB has received each type of insurance coverage for which it has
applied and during such periods has not been denied indemnification for any
material claims submitted under any of its insurance policies. FSSB Disclosure
Schedule 4.1(j) (ii) identifies all policies of insurance maintained by FSSB and
each Significant Subsidiary of FSSB.

FSSB Subsidiary, (ii) to which FSSB or any FSSB Subsidiary's assets are or may
be subject, (iii) challenging the validity or propriety of any of the
transactions contemplated by this Agreement, or (iv) which could adversely
affect the ability of FSSB to perform under this Agreement, except for any
proceeding, claim, action, investigation or inquiry referred to in clauses (i)
and (ii) which, individually or in the aggregate, would not be reasonably
expected to have a Material Adverse Effect.

FSSB's Knowledge, each of FSSB and each FSSB Subsidiary is in compliance in all

Housing Act, the Community Reinvestment Act of 1977 ("CRA"), the Home Mortgage
Disclosure Act, and all other applicable fair lending laws and other laws
relating to discriminatory business practices and neither FSSB nor any FSSB
Subsidiary has received any written notice to the contrary.

               (ii) Each of FSSB and each FSSB Subsidiary has all material
permits, licenses, authorizations orders and approvals of, and has made all
filings, applications and registrations with, all Bank Regulators that are
required in order to permit it to own or lease its properties and to conduct its
business as presently conducted; all such permits, licenses, certificates of

consummation of the transactions contemplated by this Agreement, subject to
obtaining the approvals set forth in Section 8.3.

               (iii) Except as set forth in FSSB Disclosure Schedule 4.1(l)(iii)
for the period beginning January 1, 2003, neither FSSB nor any FSSB Subsidiary
has received any written notification or, to FSSB's Knowledge, any other
communication from any Bank Regulator (i) asserting that FSSB or any FSSB
Subsidiary is not in material compliance with any of the statutes, regulations
or ordinances which such Bank Regulator enforces; (ii) threatening to


                                      A-20



revoke any license, franchise, permit or governmental authorization which is
material to FSSB or any FSSB Subsidiary; (iii) requiring or threatening to
require FSSB or any FSSB Subsidiary, or indicating that FSSB or any FSSB
Subsidiary may be required, to enter into a cease and desist order, agreement or
memorandum of understanding or any other agreement with any federal or state
governmental agency or authority which is charged with the supervision or
regulation of banks or engages in the insurance of bank deposits restricting or
limiting, or purporting to restrict or limit, in any material respect the
operations of FSSB or any FSSB Subsidiary, including without limitation any
restriction on the payment of dividends; or (iv) directing, restricting or
limiting, or purporting to direct, restrict or limit, in any material manner the
operations of FSSB or any FSSB Subsidiary (any such notice, communication,
memorandum, agreement or order described in this sentence is hereinafter
referred to as a "Regulatory Agreement"). Except as set forth in FSSB Disclosure
Schedule 4.1(l)(iii), neither FSSB nor any FSSB Subsidiary has consented to or
entered into any Regulatory Agreement that is currently in effect. Any such
Regulatory Agreement and all correspondence relating thereto is set forth in
FSSB Disclosure Schedule 4.1(l)(iii). The most recent regulatory rating given to
FSSB as to compliance with the CRA is "Satisfactory" or better.

          (m) Employee Benefit Plans.

               (i) FSSB Disclosure Schedule 4.1(m)(i) includes a descriptive
list of all existing bonus, incentive, deferred compensation, pension,
retirement, profit-sharing, thrift, savings, employee stock ownership, stock
bonus, stock purchase, restricted stock, stock option, stock appreciation,
phantom stock, severance, welfare benefit plans, fringe benefit plans,
employment, severance and change in control agreements and all other material
benefit practices, policies and arrangements maintained by FSSB or any FSSB
Subsidiary in which any employee or former employee, consultant or former
consultant or director or former director of FSSB or any FSSB Subsidiary
participates or to which any such employee, consultant or director is a party or
is otherwise entitled to receive benefits (the "Compensation and Benefit
Plans"). Except as set forth in FSSB Disclosure Schedule 4.1(m)(i), neither FSSB
nor any of its Subsidiaries has any commitment to create any additional
Compensation and Benefit Plan or to materially modify, change or renew any
existing Compensation and Benefit Plan (any modification or change that
increases the cost of such plans would be deemed material), except as required
to maintain the qualified status thereof. FSSB has made available to Farmers or
a Farmers Entity true and correct copies of the Compensation and Benefit Plans.
There are no outstanding unvested or unexercised awards under any FSSB benefit
plans and there are no awards available for issuance under any such plan.

               (ii) Except as disclosed in FSSB Disclosure Schedule 4.1(m)(ii),
each Compensation and Benefit Plan has been operated and administered in all
material respects in accordance with its terms and with applicable law,
including, but not limited to, ERISA, the Code, the Securities Act, the Exchange
Act, the Age Discrimination in Employment Act, COBRA, the Health Insurance
Portability and Accountability Act and any regulations or rules promulgated
thereunder, and all material filings, disclosures and notices required by ERISA,
the Code, the Securities Act, the Exchange Act, the Age Discrimination in
Employment Act and any other applicable law have been timely made or any
interest, fines, penalties or other impositions for late filings have been paid
in full. Each Compensation and Benefit Plan which is an


                                      A-21



"employee pension benefit plan" within the meaning of Section 3(2) of ERISA (a
"Pension Plan") and which is intended to be qualified under Section 401(a) of
the Code has received a favorable determination letter from the IRS, and FSSB is
not aware of any circumstances which are reasonably likely to result in
revocation of any such favorable determination letter. There is no material
pending or, to the Knowledge of FSSB, threatened action, suit or claim relating
to any of the Compensation and Benefit Plans (other than routine claims for
benefits). Neither FSSB nor any FSSB Subsidiary has engaged in a transaction, or
omitted to take any action, with respect to any Compensation and Benefit Plan
that would reasonably be expected to subject FSSB or any FSSB Subsidiary to an
unpaid tax or penalty imposed by either Section 4975 of the Code or Section 502
of ERISA.

               (iii) Except as set forth in FSSB Disclosure Schedule
4.1(m)(iii), no liability, other than PBGC premiums arising in the ordinary
course of business, has been or is expected by FSSB or any of its Subsidiaries
to be incurred with respect to any FSSB Compensation and Benefit Plan which is a
defined benefit plan subject to Title IV of ERISA ("FSSB Defined Benefit Plan"),
or with respect to any "single-employer plan" (as defined in Section 4001(a) of
ERISA) currently or formerly maintained by FSSB or any entity which is
considered one employer with FSSB under Section 4001(b)(1) of ERISA or Section
414 of the Code (an "ERISA Affiliate") (such plan hereinafter referred to as an
"ERISA Affiliate Plan"). To the Knowledge of FSSB and any FSSB Subsidiary,
except as set forth in FSSB Disclosure Schedule 4.1(m)(iii), no FSSB Defined
Benefit Plan had an "accumulated funding deficiency" (as defined in Section 302
of ERISA), whether or not waived, as of the last day of the end of the most
recent plan year ending prior to the date hereof. Except as set forth in FSSB
Disclosure Schedule 4.1(m)(iii), the fair market value of the assets of each
FSSB Defined Benefit Plan exceeds the present value of the benefits guaranteed
under Section 4022 of ERISA under such FSSB Defined Benefit Plan as of the end
of the most recent plan year with respect to the respective FSSB Defined Benefit
Plan ending prior to the date hereof, calculated on the basis of the actuarial
assumptions used in the most recent actuarial valuation for such FSSB Defined
Benefit Plan as of the date hereof; and no notice of a "reportable event" (as
defined in Section 4043 of ERISA) for which the 30-day reporting requirement has
not been waived has been required to be filed for any FSSB Defined Benefit Plan
within the 12-month period ending on the date hereof. Except as set forth in
FSSB Disclosure Schedule 4.1(m)(iii), neither FSSB nor any of its Subsidiaries
has provided, or is required to provide, security to any FSSB Defined Benefit
Plan or to any single-employer plan of an ERISA Affiliate pursuant to Section
401(a)(29) of the Code or has taken any action, or omitted to take any action,
that has resulted, or would reasonably be expected to result in the imposition
of a lien under Section 412(n) of the Code or pursuant to ERISA. To the
Knowledge of FSSB, and except as set forth in FSSB Disclosure Schedule
4.1(m)(iii), there is no pending investigation or enforcement action by any Bank
Regulator with respect to any Compensation and Benefit Plan or any ERISA
Affiliate Plan.

               (iv) With respect to any FSSB Defined Benefit Plan that is a
"multi-employer plan" as such term is defined in Section 3(37) of ERISA,
covering employees of FSSB or any ERISA Affiliate, (i) neither FSSB nor any
ERISA Affiliate has made or suffered a "complete withdrawal" or "partial
withdrawal," as such terms are respectively defined in Sections 4203 and 4205 of
ERISA, (ii) no event has occurred, and no circumstances exist, that alone or
with the passage of time present a material risk of a complete or partial
withdrawal, and


                                      A-22



(iii) neither FSSB or any ERISA Affiliate has any contingent liability under
Section 4204 of ERISA and no circumstances exist that present a material risk
that any such plan will go into reorganization. FSSB Disclosure Schedule
4.1(m)(iv) lists FSSB's best estimate of the amount of withdrawal liability that
would be incurred if FSSB and each ERISA Affiliate were to make a complete
withdrawal from such plan as of the Effective Time and also states the aggregate
withdrawal liability of FSSB and the ERISA Affiliate. There are no "unfunded
vested benefits" (within the meaning of Section 4211 of ERISA) as of the end of
the most recently completed plan year and as of the date of this Agreement.

          (v) All material contributions required to be made under the terms of
any Compensation and Benefit Plan or ERISA Affiliate Plan or any employee
benefit arrangements to which FSSB or any FSSB Subsidiary is a party or a
sponsor have been timely made, and all anticipated contributions and funding
obligations are accrued on FSSB's consolidated financial statements to the
extent required by GAAP. FSSB or its Subsidiaries have expensed and accrued as a
liability the present value of future benefits under each applicable
Compensation and Benefit Plan for financial reporting purposes as required by
GAAP.

          (vi) Neither FSSB nor any FSSB Subsidiary has any obligations to
provide retiree health, life insurance, disability insurance, or other retiree
death benefits under any Compensation and Benefit Plan, other than benefits
mandated by Section 4980B of the Code. Except as set forth in FSSB Disclosure
Schedule 4.1(m)(vi), there has been no communication to employees by FSSB or any
FSSB Subsidiary that would reasonably be expected to promise or guarantee such
employees retiree health, life insurance, disability insurance, or other retiree
death benefits.

          (vii) Except as set forth in FSSB Disclosure Schedule 4.1(m)(vii),
FSSB and its Subsidiaries do not maintain any Compensation and Benefit Plans
covering employees who are not United States residents.

          (viii) Except as set forth in FSSB Disclosure Schedule 4.1(m)(viii),
with respect to each Compensation and Benefit Plan, if applicable, FSSB has
provided or made available to Farmers or a Farmers Entity copies of the: (A)
trust instruments and insurance contracts, (B) two (2) most recent Forms 5500
filed with the IRS, (C) two (2) most recent actuarial reports and financial
statements; (D) most recent summary plan description, (E) most recent
determination letter issued by the IRS; (F) any Form 5310 or Form 5330 filed
with the IRS within the last two years, and (G) most recent nondiscrimination
tests performed under ERISA and the Code (including 401(k) and 401(m) tests), if
applicable.

          (ix) Except as set forth in FSSB Disclosure Schedule 4.1(m)(ix), the
consummation of the Merger will not, directly or indirectly (including, without
limitation, as a result of any termination of employment or service at any time
prior to or following the Effective Time) (A) entitle any employee, consultant
or director to any payment or benefit (including severance pay, change in
control benefit, or similar compensation) or any increase in compensation, (B)
result in the vesting or acceleration of any benefits under any Compensation and
Benefit Plan or (C) result in any material increase in benefits payable under
any Compensation and Benefit Plan.


                                      A-23


               (x) Neither FSSB nor any FSSB Subsidiary maintains any
compensation plans, programs or arrangements under which any payment is
reasonably likely to become non-deductible, in whole or in part, for tax
reporting purposes as a result of the limitations under Section 162(m) of the
Code and the regulations issued thereunder.

               (xi) To the Knowledge of FSSB, the consummation of the Merger
will not, directly or indirectly (including without limitation, as a result of
any termination of employment or service at any time prior to or following the
Effective Time), entitle any current or former employee, director or independent
contractor of FSSB or any FSSB Subsidiary to any actual or deemed payment (or
benefit) which could constitute a "parachute payment" (as such term is defined
in Section 280G of the Code).

               (xii) There are no stock appreciation or similar rights, earned
dividends or dividend equivalents, or shares of restricted stock, outstanding
under any of the Compensation and Benefit Plans or otherwise as of the date
hereof and none will be granted, awarded, or credited after the date hereof.

          (n) Brokers, Finders and Financial Advisors. Except as set forth in
FSSB Disclosure Schedule 4.1(n), neither FSSB nor any FSSB Subsidiary, nor any
of their respective officers, directors, employees or agents, has employed any
broker, finder or financial advisor other than Austin Associates, LLC in
connection with the transactions contemplated by this Agreement, or incurred any
liability or commitment for any fees or commissions to any such person other
than Austin Associates, LLC in connection with the transactions contemplated by
this Agreement.

          (o) Environmental Matters.

               (i) Except as may be set forth in FSSB Disclosure Schedule 4.1(o)

FSSB Subsidiaries in respect of such Loan Property) (x) relating to alleged
noncompliance (including by any predecessor) with, or liability under, any
Environmental Law or (y) relating to the presence of or release into the
environment of any Materials of Environmental Concern, whether or not occurring
at or on a site owned, leased or operated by a Loan Property;

                    (D) To FSSB's Knowledge, the properties currently owned or

are not contaminated with and do not otherwise contain any Materials of
Environmental Concern other than as permitted under applicable Environmental
Law;

                    (E) neither FSSB nor any FSSB Subsidiary has received any
written notice, demand letter, executive or administrative order, directive or

entity or any third party indicating that it may be in violation of, or liable
under, any Environmental Law;

                    (F) To FSSB's Knowledge, there are no underground storage

current properties or (t) FSSB's or any of the FSSB Subsidiaries' participation
in the management of any Participation Facility, there has been no contamination

                                      A-25



               (i) To FSSB's Knowledge, the allowance for loan losses reflected
in the notes to FSSB's audited consolidated statement of financial condition at
December 31, 2004 was, and the allowance for loan losses shown in the notes to
the FSSB's unaudited consolidated financial statements for periods ending after
December 31, 2004 were, or will be, adequate, as of the dates thereof, under
GAAP.

               (ii) FSSB Disclosure Schedule 4.1(p)(ii) sets forth a listing, as
of the most recently available date, by account, of: (A) each borrower, customer
or other party which has notified FSSB or any FSSB Subsidiary during the past
twelve months of, or has asserted against FSSB or any FSSB Subsidiary, in each
case in writing, any "lender liability" or similar claim, and, to the Knowledge
of FSSB, each borrower, customer or other party which has given FSSB or any FSSB
Subsidiary any oral notification of, or orally asserted to or against FSSB or
any FSSB Subsidiary, any such claim; and (B) all loans, (1) that are
contractually past due 90 days or more in the payment of principal and/or
interest, (2) that are on non-accrual status, (3) that as of the date of this
Agreement are classified as "Other Loans Specifically Mentioned", "Special
Mention", "Substandard", "Doubtful", "Loss", "Classified", "Criticized", "Watch
list" or words of similar import, together with the principal amount of and
accrued and unpaid interest on each such loan and the identity of the obligor
thereunder, (4) where the interest rate terms have been reduced and/or the
maturity dates have been extended subsequent to the agreement under which the
loan was originally created due to concerns regarding the borrower's ability to
pay in accordance with such initial terms, or (5) where a specific reserve
allocation exists in connection therewith; and (C) all other assets classified
by FSSB or any FSSB Subsidiary as real estate acquired through foreclosure or in
lieu of foreclosure, including in-substance foreclosures, and all other assets
currently held that were acquired through foreclosure or in lieu of foreclosure.

               (iii) All loans receivable (including discounts) and accrued
interest entered on the books of FSSB and the FSSB Subsidiaries arose out of
bona fide arm's-length transactions, were made for good and valuable
consideration in the ordinary course of FSSB's or the appropriate FSSB
Subsidiary's respective business, and the notes or other evidences of
indebtedness with respect to such loans (including discounts) are true and
genuine and are what they purport to be, except as set forth in FSSB Disclosure
Schedule 4.1(p)(iii). To the Knowledge of FSSB, the loans, discounts and the
accrued interest reflected on the books of FSSB and the FSSB Subsidiaries are
subject to no defenses, set-offs or counterclaims (including, without
limitation, those afforded by usury or truth-in-lending laws), except as may be
provided by bankruptcy, insolvency or similar laws affecting creditors' rights
generally or by general principles of equity. Except as set forth in FSSB
Disclosure Schedule 4.1(p)(iii), all such loans are owned by FSSB or the
appropriate FSSB Subsidiary free and clear of any liens.

               (iv) The notes and other evidences of indebtedness evidencing the
loans described above, and all pledges, mortgages, deeds of trust and other
collateral documents or security instruments relating thereto are, in all
material respects, valid, true and genuine, and what they purport to be.

          (q) Related Party Transactions. Except as set forth in FSSB Disclosure
Schedule 4.1(q), neither FSSB nor any FSSB Subsidiary is a party to any
transaction (including


                                      A-26



any loan or other credit accommodation) with any Affiliate of FSSB or any FSSB
Subsidiary. All such transactions (a) were made in the ordinary course of
business, (b) were made on substantially the same terms, including interest
rates and collateral, as those prevailing at the time for comparable
transactions with other Persons, and (c) did not involve more than the normal
risk of collectibility or present other unfavorable features. No loan or credit
accommodation to any Affiliate of FSSB or any FSSB Subsidiary is presently in
default or, during the three (3) year period prior to the date of this
Agreement, has been in default or has been restructured, modified or extended
except for rate or other modifications pursuant to FSSB's loan modification
policy that is applicable to all Persons. Neither FSSB nor any FSSB Subsidiary
has been notified that principal and interest with respect to any such loan or
other accommodation will not be paid when due or that the loan grade
classification accorded such loan or credit accommodation by FSSB is
inappropriate.

          (r) Deposits. Except as disclosed in FSSB Disclosure Schedule 4.1(f),
none of the deposits of FSSB is a "brokered deposit" as defined in 12 C.F.R.
Section 337.6(a)(2).

          (s) Required Vote. The affirmative vote of not less than 2/3rds of the
issued and outstanding shares of FSSB Common Stock is required to approve this
Agreement and the Merger under FSSB's Articles of Incorporation and Michigan
law.

          (t) Intellectual Property. FSSB and each Significant Subsidiary of
FSSB owns or, to FSSB's Knowledge, possesses valid and binding licenses and
other rights to use all patents, copyrights, trade secrets, trade names,
servicemarks and trademarks used in their business, each without payment, and
neither FSSB nor any Significant Subsidiary of FSSB has received any notice of
conflict with respect thereto that asserts the rights of others. FSSB and each
Significant Subsidiary of FSSB have performed all the obligations required to be
performed, and are not in default in any respect, under any contract, agreement,
arrangement or commitment relating to any of the foregoing.

          (u) Administration of Trust Accounts. FSSB and each FSSB Subsidiary
has properly administered in all material respects and which could reasonably be
excepted to be material to the financial condition of FSSB and the FSSB
Subsidiaries taken as a whole, all accounts for which it acts as a fiduciary,
including but not limited to accounts for which it serves as a trustee, agent,
custodian, personal representative, guardian, conservator or investment advisor,
in accordance with the terms of the governing documents and applicable state and
federal law and regulations and common law. To the Knowledge of FSSB, neither
FSSB, any FSSB Subsidiary, nor any director, officer or employee of FSSB or any
FSSB Subsidiary has committed any breach of trust with respect to any such
fiduciary account which is material to or could reasonably be expected to be
material to the financial condition of FSSB and the FSSB Subsidiaries taken as a
whole, and the accountings for each such fiduciary account are true and correct
in all material respects and accurately reflect the assets of such fiduciary
account.

employee, independent contractor, creditor, shareholder or other third party,
and Farmers, IBT and each of its Significant Subsidiaries, to the Knowledge of
Farmers, has timely complied with all applicable information reporting
requirements under Part III, Subchapter A of Chapter 61 of the Code and similar
applicable state and local information reporting requirements.

          (g) No Material Adverse Effect. Except as disclosed in IBT's
Securities Documents filed on or prior to the date hereof, Farmers and the
Farmers Entities, taken as a whole, have not suffered any Material Adverse
Effect since December 31, 2004 and to Farmers' Knowledge, no event has occurred
or circumstance arisen since that date which, in the aggregate, has had or is
reasonably likely to have a Material Adverse Effect on Farmers and the Farmers
Entities, taken as a whole.

          (h) Ownership of Property; Insurance Coverage.

               (i) Farmers and each Farmers Entity has good and, as to real
property, marketable title to all material assets and properties owned by
Farmers or any Farmers Entity in the conduct of its businesses, whether such
assets and properties are real or personal, tangible or intangible, including
assets and property reflected in the balance sheet contained in the most recent
IBT Financial Statements or acquired subsequent thereto (except to the extent
that such assets and properties have been disposed of in the ordinary course of
business, since the date of such balance sheet), subject to no material
encumbrances, liens, mortgages, security interests or pledges, except (i) those
items which secure liabilities for public or statutory obligations or any
discount with, borrowing from or other obligations to FHLB, inter-bank credit
facilities or any transaction by Farmers or IBT acting in a fiduciary capacity,
and (ii) statutory liens for amounts not yet delinquent or which are being
contested in good faith. Farmers and each Farmers Entity, as lessee, have the
right under valid and existing leases of real and personal properties used by
Farmers and each Farmers Entity in the conduct of their businesses to occupy or
use all such properties as presently occupied and used by each of them. Such
existing leases and commitments to lease constitute or will constitute operating
leases for both tax and financial accounting purposes and the lease expense and
minimum rental commitments with respect to such leases and lease commitments are
as disclosed in all material respects in the notes to the IBT Financial
Statements.

               (ii) Farmers and each Farmers Entity currently maintain insurance
considered by each of them to be reasonable for their respective operations.
Neither Farmers nor any Farmers Entity has received notice from any insurance
carrier that (i) such insurance will be


                                      A-31



canceled or that coverage thereunder will be reduced or eliminated, or (ii)
premium costs with respect to such policies of insurance will be substantially
increased. There are presently no material claims pending under such policies of
insurance and no notices of material claims have been given by Farmers, or any
Farmers Entity under such policies. All such insurance is valid and enforceable
and in full force and effect, and within the last three (3) years Farmers and
each Farmers Entity has received each type of insurance coverage for which it
has applied and during such periods has not been denied indemnification for any
material claims submitted under any of its insurance policies. Farmers Entity
Disclosure Schedule 5.1(h) (ii) identifies all policies of insurance maintained
by Farmers and each Farmers Entity.

          (i) Legal Proceedings. Except as disclosed in Farmers Entity
Disclosure Schedule 5.1(i), neither Farmers nor any Farmers Entity is a party to
any, and there are no pending or, to Farmers' and IBT's Knowledge, threatened

any Farmers Entity's assets are or may be subject, (iii) challenging the
validity or propriety of any of the transactions contemplated by this Agreement,
or (iv) which could adversely affect the ability of Farmers or any Farmers
Entity to perform under this Agreement, except for any proceeding, claim,
action, investigation or inquiry referred to in clauses (i) and (ii) which,
individually or in the aggregate, would not be reasonably expected to have a
Material Adverse Effect.

Farmers Entity is in compliance in all material respects with all applicable

deposits, its business, and its conduct of business and its relationship with
its employees, including, without limitation, the USA PATRIOT Act, the Bank
Secrecy Act, the Equal Credit Opportunity Act, the Fair Housing Act, the CRA,
the Home Mortgage Disclosure Act, and all other applicable fair lending laws and
other laws relating to discriminatory business practices and neither Farmers nor
any Farmers Entity has received any written notice to the contrary.

               (ii) Each of Farmers and each Farmers Entity has all material
permits, licenses, authorizations, orders and approvals of, and has made all
filings, applications and registrations with, all Bank Regulators that are
required in order to permit it to own or lease its properties and to conduct its
business as presently conducted; all such permits, licenses, certificates of

Knowledge of Farmers, no suspension or cancellation of any such permit, license,

obtaining the approvals set forth in Section 8.3.

               (iii) For the period beginning January 1, 2003, neither Farmers

asserting that Farmers or any Farmers Entity is not


                                      A-32



in material compliance with any of the statutes, regulations or ordinances which
such Bank Regulator enforces; (ii) threatening to revoke any license, franchise,
permit or governmental authorization which is material to Farmers or any Farmers
Entity; (iii) requiring or threatening to require Farmers or any Farmers Entity,
or indicating that Farmers or any Farmers Entity may be required, to enter into
a cease and desist order, agreement or memorandum of understanding or any other
agreement with any federal or state governmental agency or authority which is
charged with the supervision or regulation of banks or engages in the insurance
of bank deposits restricting or limiting, or purporting to restrict or limit, in
any material respect the operations of Farmers or any Farmers Entity, including
without limitation any restriction on the payment of dividends; or (iv)
directing, restricting or limiting, or purporting to direct, restrict or limit,
in any manner the operations of Farmers or any Farmers Entity, including without
limitation any restriction on the payment of dividends (any such notice,
communication, memorandum, agreement or order described in this sentence is
hereinafter referred to as a "Regulatory Agreement"). Neither Farmers nor any
Farmers Entity has consented to or entered into any currently effective

Such reports and proxy materials complied, at the time filed with the SEC, in
all material respects, with the Securities Laws.

          (n) Reorganization. Farmers and IBT have no knowledge of any reason
why the Merger would fail to qualify as a reorganization under Section 368(a) of
the Code.

          (o) Information Supplied. None of the information supplied or to be

          (t) Employee Benefit Plans.

               (i) Except as disclosed in Farmers Entity Disclosure Schedule
5.1(t)(i), each bonus, incentive, deferred compensation, pension, retirement,
profit-sharing, thrift, savings, employee stock ownership, stock bonus, stock
purchase, restricted stock, stock option, stock appreciation, phantom stock,
severance, welfare benefit plans, fringe benefit plans, employment, severance
and change in control agreements and all other material benefit practices,
policies and arrangements maintained by Farmers or any Farmers Entity (the
"Farmers Entity Plans") has been operated and administered in all material
respects in accordance with its terms and with applicable law, including, but
not limited to, ERISA, the Code, the Securities Act, the Exchange Act, the Age
Discrimination in Employment Act, COBRA, the Health Insurance Portability and
Accountability Act and any regulations or rules promulgated thereunder, and all
material filings, disclosures and notices required by ERISA, the Code, the
Securities Act, the Exchange Act, the Age Discrimination in Employment Act and
any other applicable law have been timely made or any interest, fines, penalties
or other impositions for late filings have been paid in full. Each Farmers
Entity Plan which is an "employee pension benefit plan" within the meaning of
Section 3(2) of ERISA (a "Pension Plan") and which is intended to be qualified
under Section 401(a) of the Code has received a favorable determination letter
from the IRS, and Farmers is not aware of any circumstances which are reasonably
likely to result in revocation of any such favorable determination letter. There
is no material pending or, to the Knowledge of Farmers or IBT, threatened
action, suit or claim relating to any of the Compensation and Benefit Plans
(other than


                                      A-34



routine claims for benefits). Neither Farmers nor any Farmers Entity has engaged
in a transaction, or omitted to take any action, with respect to any
Compensation and Benefit Plan that would reasonably be expected to subject
Farmers or any Farmers Entity to an unpaid tax or penalty imposed by either
Section 4975 of the Code or Section 502 of ERISA.

               (ii) Except as set forth in Farmers Entity Disclosure Schedule
5.1(t)(ii), no liability, other than PBGC premiums arising in the ordinary
course of business, has been or is expected by Farmers or any Farmers Entity to
be incurred with respect to any Farmers Entity Plan which is a defined benefit
plan subject to Title IV of ERISA ("Farmers Entity Defined Benefit Plan"), or
with respect to any "single-employer plan" (as defined in Section 4001(a) of
ERISA) currently or formerly maintained by Farmers, any Farmers Entity or any
entity which is considered one employer with Farmers under Section 4001(b)(1) of
ERISA or Section 414 of the Code (a "Farmers Entity ERISA Affiliate") (such plan
hereinafter referred to as a "Farmers Entity ERISA Affiliate Plan"). To the
Knowledge of Farmers and IBT, except as set forth in Farmers Entity Disclosure
Schedule 5.1(t)(ii), no Farmers Entity Defined Benefit Plan had an "accumulated
funding deficiency" (as defined in Section 302 of ERISA), whether or not waived,
as of the last day of the end of the most recent plan year ending prior to the
date hereof. Except as set forth in Farmers Entity Disclosure Schedule
5.1(t)(ii), the fair market value of the assets of each Farmers Entity Defined
Benefit Plan exceeds the present value of the benefits guaranteed under Section
4022 of ERISA under such Farmers Entity Defined Benefit Plan as of the end of
the most recent plan year with respect to the respective Farmers Entity Defined
Benefit Plan ending prior to the date hereof, calculated on the basis of the
actuarial assumptions used in the most recent actuarial valuation for such
Farmers Entity Defined Benefit Plan as of the date hereof; and no notice of a
"reportable event" (as defined in Section 4043 of ERISA) for which the 30-day
reporting requirement has not been waived has been required to be filed for any
Farmers Entity Defined Benefit Plan within the 12-month period ending on the
date hereof. Except as set forth in Farmers Entity Disclosure Schedule
5.1(t)(ii), neither Farmers nor any Farmers Entity has provided, or is required
to provide, security to any Farmers Entity Defined Benefit Plan or to any
single-employer plan of a Farmers Entity ERISA Affiliate pursuant to Section
401(a)(29) of the Code or has taken any action, or omitted to take any action,
that has resulted, or would reasonably be expected to result in the imposition
of a lien under Section 412(n) of the Code or pursuant to ERISA. To the
Knowledge of Farmers and IBT, and except as set forth in Farmers Entity
Disclosure Schedule 5.1(t)(ii), there is no pending investigation or enforcement
action by any Bank Regulator with respect to any Farmers Plan or any Farmers
Entity ERISA Affiliate Plan.

               (iii) With respect to any Farmers Entity Defined Benefit Plan
that is a "multi-employer plan" as such term is defined in Section 3(37) of
ERISA, covering employees of Farmers, any Farmers Entity or any Farmers Entity
ERISA Affiliate, (i) neither Farmers, any Farmers Entity, nor any Farmers Entity
ERISA Affiliate has made or suffered a "complete withdrawal" or "partial
withdrawal," as such terms are respectively defined in Sections 4203 and 4205 of
ERISA, (ii) no event has occurred, and no circumstances exist, that alone or
with the passage of time present a material risk of a complete or partial
withdrawal, and (iii) neither Farmers, any Farmers Entity, or any Farmers Entity
ERISA Affiliate has any contingent liability under Section 4204 of ERISA and no
circumstances exist that present a material risk that any such plan will go into
reorganization. Farmers Entity Disclosure Schedule 5.1(t)(iii) lists IBT's


                                      A-35



best estimate of the amount of withdrawal liability that would be incurred if
Farmers, each Farmers Entity and each Farmers Entity ERISA Affiliate were to
make a complete withdrawal from such plan as of the Effective Time and also
states the aggregate withdrawal liability of Farmers, the Farmers Entities and
the Farmers Entity ERISA Affiliates. There are no "unfunded vested benefits"
(within the meaning of Section 4211 of ERISA) as of the end of the most recently
completed plan year and as of the date of this Agreement.

               (iv) All material contributions required to be made under the
terms of any Farmers Plan or Farmers Entity ERISA Affiliate Plan or any employee
benefit arrangements to which Farmers or any Farmers Entity is a party or a
sponsor have been timely made, and all anticipated contributions and funding
obligations are accrued on IBT's consolidated financial statements to the extent
required by GAAP. Farmers or any Farmers Entity have expensed and accrued as a
liability the present value of future benefits under each applicable Farmers
Entity Plan for financial reporting purposes as required by GAAP.

               (v) Neither Farmers nor any Farmers Entity has any obligations to
provide retiree health, life insurance, disability insurance, or other retiree
death benefits under any Farmers Entity Plan, other than benefits mandated by
Section 4980B of the Code.

          (u) Loan Portfolio.

               (i) To IBT's Knowledge, the allowance for loan losses reflected
in the notes to IBT's audited consolidated statement of financial condition at
December 31, 2004 was, and the allowance for loan losses shown in the notes to
the IBT's unaudited consolidated financial statements for periods ending after
December 31, 2004 were, or will be, adequate, as of the dates thereof, under
GAAP.

               (ii) Farmers Entity Disclosure Schedule 5.1(u) sets forth a
listing, as of the most recently available date, by account, of all loans having
a principal balance in excess of $750,000 (1) that are contractually past due 90
days or more in the payment of principal and/or interest, (2) that are on
non-accrual status, (3) that as of the date of this Agreement are classified as
"Other Loans Specifically Mentioned", "Special Mention", "Substandard",
"Doubtful", "Loss", "Classified", "Criticized", "Watch list" or words of similar
import, together with the principal amount of and accrued and unpaid interest on
each such loan and the identity of the obligor thereunder, (4) where the
interest rate terms have been reduced and/or the maturity dates have been
extended subsequent to the agreement under which the loan was originally created
due to concerns regarding the borrower's ability to pay in accordance with such
initial terms, or (5) where a specific reserve allocation exists in connection
therewith.

               (iii) All loans receivable (including discounts) and accrued
interest entered on the books of Farmers and the Farmers Entities arose out of
bona fide arm's-length transactions, were made for good and valuable
consideration in the ordinary course of Farmers' or the appropriate Farmers
Entity's respective business, and the notes or other evidences of indebtedness
with respect to such loans (including discounts) are true and genuine and are
what they purport to be, other than loans as to which the failure to satisfy the
foregoing standards would not have a Material Adverse Effect on Farmers or any
of the Farmers Entities.

and each FSSB Subsidiary shall permit, upon reasonable notice, Farmers or a
designated Farmers Entity at its own expense to cause a "phase I environmental

FSSB will promptly supplement or amend the FSSB Disclosure Schedule delivered in
connection herewith with respect to any matter hereafter arising which, if
existing, occurring or known at the date of this Agreement, would have been

cause to be taken, all action and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement,
except to the extent that such action, in the good faith determination of the
board of directors of FSSB after consultation with legal counsel, may result in
a breach of fiduciary duty by the FSSB board of directors.

     6.9. Failure to Fulfill Conditions. In the event that FSSB determines that
a condition to its obligation to complete the Merger cannot be fulfilled and
that it will not waive that condition, it will promptly notify Farmers.

     6.10. No Solicitation. From and after the date hereof until the termination
of this Agreement, neither FSSB, nor any FSSB Subsidiary, nor any of their
respective officers, directors, employees, representatives, agents and
Affiliates (including, without limitation, any investment banker, attorney or
accountant retained by FSSB or any of the FSSB Subsidiaries), will, directly or
indirectly, initiate, solicit or knowingly encourage (including by way of
furnishing non-public information or assistance) any inquiries or the making of
any proposal that constitutes, or may reasonably be expected to lead to, any
Acquisition Proposal (as defined below), or enter into or maintain or continue
discussions or negotiate with any Person in furtherance of such inquiries or to
obtain an Acquisition Proposal or agree to or endorse any Acquisition Proposal,
or authorize or permit any of its officers, directors, or employees or any of
its Subsidiaries or any investment banker, financial advisor, attorney,
accountant or other representative retained by any of its Subsidiaries to take
any such action, and FSSB shall notify Farmers orally (within one business day)
and in writing (as promptly as practicable) of all of the relevant details
relating to all inquiries and proposals which it or any of its Subsidiaries or
any such officer, director or employee, or, to FSSB's Knowledge, investment
banker, financial advisor, attorney, accountant or other representative of FSSB
may receive relating to any of such matters, provided, however, that nothing
contained in this Section 6.10 shall prohibit the Board of Directors of FSSB
from (i) complying with its disclosure obligations under federal or state law;
or (ii) furnishing information to, or entering into discussions or negotiations
with, any person or entity that makes an unsolicited Acquisition Proposal, if,
and only to the extent that, (A) the Board of Directors of FSSB determines in
good faith (after consultation with its financial and legal advisors), taking
into account all legal, financial and regulatory aspects of the proposal


                                      A-42



and the Person making the proposal, that such proposal, if consummated, is
reasonably likely to result in a transaction more favorable to FSSB's
shareholders from a financial point of view than the Merger; (B) the Board of
Directors of FSSB determines in good faith (after consultation with its
financial and legal advisors) that the failure to furnish information to or
enter into discussions with such Person would likely cause the Board of
Directors to breach its fiduciary duties to shareholders under applicable law
(such proposal that satisfies clause (A) and (B) being referred to herein as a
"Superior Proposal"); and (C) FSSB promptly notifies Farmers of such inquiries,
proposals or offers received by, any such information requested from, or any
such discussions or negotiations sought to be initiated or continued with FSSB
or any of its representatives indicating, in connection with such notice, the
name of such Person and the material terms and conditions of any inquiries,
proposals or offers, and receives from such Person an executed confidentiality
agreement in form and substance identical in all material respects to the
confidentiality agreements that FSSB and IBT entered into. For purposes of this
Agreement, "Acquisition Proposal" shall mean any proposal or offer as to any of
the following (other than the transactions contemplated hereunder) involving
FSSB or any of its Subsidiaries: (i) any merger, consolidation, share exchange,
business combination, or other similar transactions; (ii) any sale, lease,
exchange, mortgage, pledge, transfer or other disposition of 25% or more of the
assets of FSSB and the FSSB Subsidiaries, taken as a whole, in a single
transaction or series of transactions; (iii) any sale or tender offer or
exchange offer for 25% or more of the outstanding shares of capital stock of
FSSB or the filing of a registration statement under the Securities Act in
connection therewith; or (iv) any public announcement of a proposal, plan or
intention to do any of the foregoing or any agreement to engage in any of the
foregoing.

     6.11. Sarbanes-Oxley Certification of Financial Statements. The Chief
Executive Officer and the Chief Financial Officer of FSSB shall certify the FSSB
Financial Statements in the form attached as Exhibit A.

in accordance with Section 201 of the Sarbanes-Oxley Act of 2002 and the
regulations promulgated thereunder.

     7.1. Conduct of Business. During the period from the date of this Agreement
to the Effective Time, except with the written consent of FSSB, which consent

and they will cause each Farmers Entity to: conduct its business only in the
usual, regular and ordinary course consistent with past practices; use
reasonable efforts to preserve intact its business organization and assets and
maintain its rights and franchises; and voluntarily take no action that would:
(i) adversely affect the ability of the parties to obtain the Regulatory
Approvals or materially increase the period of time necessary to obtain such
approvals; (ii) adversely affect its ability to perform its covenants and
agreements under this Agreement; (iii) result in the representations and
warranties contained in Article V of this Agreement not being true and correct
on the date of this Agreement or at any future date on or prior to the Closing
Date or in any of the conditions set forth in Article IX hereof not being
satisfied; (iv) change or waive any provision of its Articles of Incorporation,
except as required by law; or (v) change any method, practice or principle of


                                      A-43



accounting, except as may be required from time to time by GAAP (without regard
to any optional early adoption date) or any Bank Regulator responsible for
regulating IBT, Isabella Bank and Trust or Farmers. Additionally, IBT will not
declare an extraordinary dividend or distribution on shares of IBT Common Stock.

     7.2. Disclosure Supplements. From time to time prior to the Effective Time,
Farmers and IBT will promptly supplement or amend the Farmers Entity Disclosure
Schedule delivered in connection herewith with respect to any matter hereafter
arising which, if existing, occurring or known at the date of this Agreement,
would have been required to be set forth or described in such Farmers Entity
Disclosure Schedule or which is necessary to correct any information in such
Farmers Entity Disclosure Schedule which has been rendered inaccurate thereby.

     7.3. Consents and Approvals of Third Parties. Farmers shall use all
commercially reasonable efforts to obtain as soon as practicable all consents
and approvals of any other Persons necessary or desirable for the consummation
of the transactions contemplated by this Agreement.

     7.4. All Reasonable Efforts. Subject to the terms and conditions herein
provided, Farmers agrees to use all commercially reasonable efforts to take, or

as required by ERISA, Farmers and IBT shall cause the employee pension benefit
plans of IBT (as defined under ERISA) to be adopted by Farmers for all FSSB
employees who were employed as of the Effective Time (the "Former FSSB
Employees"). All Former FSSB Employees who become participants in an IBT
employee pension benefit plan covered under ERISA shall, for purposes of
determining eligibility for and for any applicable vesting periods of such
employee benefits only (and not for benefit accrual purposes) be given credit
for meeting eligibility and vesting requirements in such plans for service as an
employee of FSSB or any predecessor thereto prior to the Effective Time. All
Former FSSB Employees who become participants in the plans of IBT shall receive
aggregate annual employer contributions of 15% of salary into such plans. To the
extent said contributions do not equal at least 15% of salary, said shortfall
shall be made up as additional salary or pursuant to a contribution to a
non-qualified plan for affected employees, as determined in the sole discretion

Farmers or the Farmers Entities to terminate the employment of any employee or
to review employee pension benefits programs from time to time and to make such
changes as it may deem appropriate. Farmers and IBT shall, from and after the
Effective Time, continue in effect any material welfare benefit plan, life
insurance, group health plan or disability plan in which the


                                      A-44



employees of FSSB participated immediately prior to the Effective Time (or an
arrangement providing substantially similar benefits). Farmers and the Farmers
Entities shall not take any action which would adversely affect the employees of
FSSB participation in or materially reduce any benefits under any such plan or
arrangement. Nothing contained in this subsection shall limit Farmers' or any
Farmers Entity's right to amend or terminate any plan or arrangement to conform
such plan or arrangement to statutory or regulatory requirements applicable to
such plan or arrangement.

papers and records relating to the assets, properties, operations, obligations
and liabilities, including, but not limited to, all books of account (including
the general ledger), tax records, minute books of directors' (other than minutes
that discuss any of the transactions contemplated by this Agreement or any other
subject matter IBT reasonably determines should be treated as confidential or
privileged) and shareholders' meetings, organizational documents, bylaws,
material contracts and agreements, filings with any regulatory authority,
litigation files (to the extent not resulting in waiver of attorney-client
privilege), plans affecting employees, and any other business activities or
prospects in which FSSB may have a reasonable interest. IBT shall provide and
shall request IBT's auditors to provide FSSB with such historical financial
information regarding it (and related audit reports and consents) as FSSB may
request.

     7.8. Financial and Other Statements.

          (a) Promptly upon receipt thereof, IBT shall furnish to FSSB copies of
each annual, interim or special audit of the books of IBT made by its

          (b) Promptly after IBT's board meeting but no later than thirty (30)
days after the end of each month, Farmers shall cause IBT to deliver to FSSB a
consolidated balance sheet and a consolidated statement of operations, without
related notes, for such month prepared in accordance with current financial
reporting practices.

          (c) Farmers and IBT shall advise FSSB promptly of the receipt of any
examination report of any Bank Regulator with respect to the condition or
activities of IBT, Farmers or any IBT Subsidiaries.

          (d) With reasonable promptness, IBT shall furnish to FSSB such
additional financial data that IBT possesses and as FSSB may reasonably request,

reports.

     7.9. Directors and Officers Indemnification; Insurance.

          (a) From and after the Effective Time through the fifth anniversary of
the Effective Time, Farmers and the Farmers Entities (collectively the
"Indemnifying Party") shall indemnify and hold harmless each present and former
director, officer and employee of FSSB,


                                      A-45



determined as of the Effective Time (the "Indemnified Parties") against any
costs or expenses (including reasonable attorneys' fees), judgments, fines,
losses, claims, damages or liabilities incurred in connection with any claim,
action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of matters existing or occurring at
or prior to the Effective Time, whether asserted or claimed prior to, at or
after the Effective Time, arising in whole or in part out of or pertaining to
the fact that he or she was a director, officer, employee, fiduciary or agent of
FSSB or any FSSB Subsidiary or is or was serving at the request of FSSB or any
FSSB Subsidiary as a director, officer, employee, fiduciary or agent of another
corporation, partnership, joint venture, trust or other enterprise, including
without limitation matters related to the negotiation, execution and performance
of this Agreement or the consummation of the Merger, to the fullest extent which
indemnification is permitted under the applicable provisions of the Michigan
Banking Code, MCL 487.13904 through 487.13907, as in effect on the date hereof
or in the event any subsequent amendment thereto expands the permissible scope
of indemnification, then as amended.

          (b) Any Indemnified Party wishing to claim indemnification under this
Section 7.9 hereof, upon learning of any such claim, action, suit, proceeding or
investigation, shall promptly notify the Indemnifying Party, but the failure to
so notify shall not relieve the Indemnifying Party of any liability it may have
to such Indemnified Party if such failure does not actually prejudice the
Indemnifying Party. In the event of any such claim, action, suit, proceeding or
investigation (whether arising before or after the Effective Time), (i) the
Indemnifying Party shall have the right to assume the defense thereof and the
Indemnifying Party shall not be liable to such Indemnified Parties for any legal
expenses of other counsel or any other expenses subsequently incurred by such
Indemnified Parties in connection with the defense thereof, except that if the
Indemnifying Party elects not to assume such defense or counsel for the
Indemnified Parties advises that there are issues which raise conflicts of
interest between the Indemnifying Party and the Indemnified Parties, the
Indemnified Parties may retain counsel which is reasonably satisfactory to the
Indemnifying Party, and the Indemnifying Party shall pay, promptly as statements
therefore are received, the reasonable fees and expenses of such counsel for the
Indemnified Parties (which may not exceed one firm in any jurisdiction), (ii)
the Indemnified Parties will cooperate in the defense of any such matter, (iii)
the Indemnifying Party shall not be liable for any settlement effected without
its prior written consent, and (iv) the Indemnifying Party shall have no
obligation hereunder in the event that a federal or state banking agency or a
court of competent jurisdiction shall determine that indemnification of an
Indemnified Party in the manner contemplated hereby is prohibited by applicable
laws and regulations.

          (c) Prior to the Effective Time, Farmers shall cause the persons
serving as directors and officers of FSSB and any FSSB Subsidiaries immediately
prior to the Effective Time to be covered by the directors' and officers'
liability insurance policy maintained by FSSB for a period of five years after
the Effective Time (provided that Farmers may substitute therefore policies of
at least the same coverage and amounts containing terms and conditions which are
not materially less advantageous than such policy or single premium tail
coverage with policy limits equal to FSSB's existing coverage limits) with
respect to acts or omissions occurring prior to the Effective Time which were
committed by such directors and officers in their capacities as such.


                                      A-46



          (d) If Farmers or any of its successors or assigns shall consolidate
with or merge into any other entity and shall not be the continuing or surviving
entity of such consolidation or merger or shall transfer all or substantially
all of its assets to any other entity, then and in each case, proper provisions
shall be made so that the successors and assigns of Farmers or the surviving
company shall assume the obligations set forth in this Section 7.9 hereof prior
to or simultaneously with the consummation of such transaction.

Entities.

impose any term, condition or restriction upon FSSB, Farmers or any of their
respective Affiliates that FSSB or Farmers, in good faith, reasonably determines

July __, 2006

Board of Directors
IBT Bancorp, Inc.
200 East Broadway
Mount Pleasant, MI 48858

and

Board of Directors
The Farwell State Savings Bank
399 West Main Street
Farwell, MI 48622

Members of the Board:

You have requested our opinion as to the fairness, from a financial point of
view, to IBT Bancorp, Inc. ("IBT") and The Farwell State Savings Bank
("Farwell") and their respective shareholders of the terms of the Amended and
Restated Agreement and Plan of Merger dated as of April 28, 2006 ("Agreement")
between IBT, Farwell, and Farmers State Bank of Breckenridge ("Farmers").
Farmers is a wholly-owned subsidiary of IBT. The terms of the Agreement provide
for the merger of Farwell with and into Farmers. At the effective time of the
merger, Farmers will change its name to FSB Bank.

The terms of the Agreement provide for each outstanding share of Farwell common
stock to be exchanged for 3.0382 shares of IBT common stock plus $29.00 in cash.
IBT will not issue fractional shares in connection with the merger; instead,
fractional shares shall be settled in cash.

In carrying out our engagement, we have reviewed and analyzed material bearing
upon the financial and operating condition of IBT and Farwell, including but not
limited to the following: (i) the Agreement; (ii) the financial statements of
IBT and Farwell for the period 2001 through year-to-date March 31, 2006; (iii)
certain other publicly available information regarding IBT and Farwell; (iv)
publicly available information regarding the performance of certain other
companies whose business activities were believed by Austin Associates to be
generally comparable to those of IBT and Farwell; (v) the financial terms, to
the extent publicly available, of certain comparable transactions; and (vi) such
other analysis and information as we deemed relevant.

In our review and analysis, we relied upon and assumed the accuracy and
completeness of the financial and other information provided to us or publicly
available, and have not attempted to verify the same. We have made no
independent verification as to the status of individual loans made by IBT or
Farwell, and have instead relied upon representations and information concerning
loans of IBT and Farwell in the aggregate.

In addition, we have assumed in the course of obtaining the necessary approvals
for the transaction, no condition will be imposed that will have a material
adverse effect on the contemplated benefits of the transaction to IBT or Farwell
and their respective shareholders.

This opinion is based on economic and market conditions and other circumstances
existing on, and information made available as of, the date hereof. This opinion
is limited to the fairness of the financial terms of the Agreement to IBT and
Farwell and their respective shareholders, and does not address the underlying
business decision by the Boards of Directors to pursue the merger.

Austin Associates will receive a contingent fee based on consummation of the
transaction. In addition, IBT and Farwell have agreed to indemnify Austin
Associates against certain liabilities.

Board of Directors
The Farwell State Savings Bank
399 W. Main St.
Farwell, Michigan 48622-0099

Members of the Board of Directors:

You have requested our opinion as to the fairness, from a financial point of
view, to the shareholders of Farwell State Savings Bank ("Farwell") of the
exchange ratio and cash consideration provided for pursuant to the Agreement of
Agreement and Plan of Merger, dated as of December 22, 2005 to which IBT
Bancorp, Inc. ("IBT") will acquire Farwell. On May 2, 2006 IBT, Farmers State
Bank of Breckenridge ("Farmers") and Farwell entered into an amended and
restated Agreement and Plan of Merger (the "Amended Agreement") to substitute
Farmers as the acquiring entity. In accordance with the terms of the Amended
Agreement, Farwell will merge with Farmers as the surviving entity.
Concurrently, each share of Farwell common stock issued and outstanding
immediately prior to the effective time of the merger shall be converted into
the right to receive 3.0382 shares of IBT common stock plus $29.00 in cash.

Donnelly Penman & Partners ("Donnelly Penman") is an investment-banking firm of
recognized standing. As part of our investment banking services, we are
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, private placements and valuations for
stock plans, corporate and other purposes. We are acting as financial advisor to
Farwell in connection with the Merger and will receive a fee from Farwell for
our services pursuant to the terms of our engagement letter with Farwell, dated
as of January 18, 2006 (the "Engagement Letter").

In arriving at its opinion, Donnelly Penman engaged in discussions with members
of the management teams of each of Farwell and IBT concerning the historical and
current business operations, financial conditions and prospects of Farwell and
IBT and reviewed:

         o        the Agreement and Plan of Merger dated December 22, 2005 and
                  the Amended and Restated Agreement and Plan of Merger dated
                  May 2, 2006;

         o        the most recent draft dated June 29, 2006 of the Form S-4
                  Registration Statement relating to the merger;

         o        certain publicly-available information for IBT, including each
                  of the Annual Reports to Stockholders and Annual Reports on
                  Form 10-K for the years ended December 31, 2003, 2004 and 2005
                  and the quarterly reports on Form 10-Q for the quarter ended
                  March 31, 2006;

         o        certain information, including financial forecasts, relating
                  to earnings, assets, liabilities and prospects of IBT
                  furnished by senior management of IBT;

         o        Independent Auditor's Report for Farwell State Bank for the
                  years ended December 31, 2005 and 2004 and the unaudited
                  condensed balance sheet and statement of income for the three
                  months ended March 31, 2006 and March 31, 2005;

         o        certain information, including financial forecasts, relating
                  to earnings, assets, liabilities and prospects of Farwell
                  furnished by senior management of Farwell;

         o        IBT's senior management projected earnings estimates for
                  fiscal years 2006 through 2010, which were deemed reasonable
                  by IBT management;

         o        Farwell's senior management projected earnings estimates for
                  fiscal years 2006 through 2010, which were deemed reasonable
                  by Farwell management;

         o        the amount and timing of the cost savings expected to result
                  from the merger furnished by senior management of IBT;

         o        the financial condition and operating results of IBT and
                  Farwell compared to the financial conditions and operating
                  results of certain other financial institutions that Donnelly
                  Penman deemed comparable;

         o        various valuation analyses of Farwell and IBT Donnelly Penman
                  performed including dividend discount analyses, analysis of
                  comparable transactions and analysis of comparable companies;
                  and

         o        such other information, financial studies, analyses and
                  investigations and such other factors that Donnelly Penman
                  deemed relevant for the purposes of its opinion.

In conducting its review and arriving at its opinion, as contemplated under the
terms of its engagement by Farwell, Donnelly Penman, with the consent of IBT and
Farwell, relied, without independent investigation, upon the accuracy and
completeness of all financial and other information provided to it by IBT and
Farwell or upon publicly-available information. Donnelly Penman did not
undertake any responsibility for the accuracy, completeness or reasonableness
of, or any obligation independently to verify, such information. Donnelly Penman
further relied upon the assurance of management of IBT and Farwell that they
were unaware of any facts that would make the information provided or available
to Donnelly Penman incomplete or misleading in any respect. Donnelly Penman did
not make any independent evaluations, valuations or appraisals of the assets or
liabilities of IBT or Farwell. Donnelly Penman did not review any individual
credit files of IBT or Farwell and assumed that the aggregate allowances for
credit losses for IBT and Farwell were adequate to cover such losses. Donnelly
Penman's opinion was necessarily based upon economic and market conditions and
other circumstances as they existed and evaluated by Donnelly Penman on the date
of its opinion. Donnelly Penman does not have any obligation to update its
opinion, unless requested by Farwell in writing to do so, and Donnelly Penman
expressly disclaims any responsibility to do so in the absence of any written
request by Farwell.

No limitations were imposed by Farwell on Donnelly Penman on the scope of
Donnelly Penman's investigation or the procedures to be followed by Donnelly
Penman in rendering this opinion. The form and amount of the consideration to be
paid to Farwell or its shareholders were determined through arms length
negotiations between Farwell and IBT.

In our analyses, we have made numerous assumptions with respect to industry
performance, business and economic conditions, and other matters, many of which
are beyond the control of Farwell. Any estimates contained in our analyses are
not necessarily indicative of future results or value, which may be
significantly more or less favorable than such estimates. Estimates of values of
companies do not purport to be appraisals or to necessarily reflect the prices
at which companies or their securities actually may be sold. No company or
merger utilized in our analyses was identical to Farwell, IBT or the Merger.
Accordingly, such analyses are not based solely on arithmetic calculations;
rather, they involve complex considerations and judgments concerning differences
in financial and operating characteristics of the relevant companies, the timing
of the relevant mergers and prospective buyer interests, as well as other
factors that could affect the public trading markets of Farwell or companies to
which it is being compared. None of the analyses performed by us was assigned a
greater significance than any other.

We hereby consent to the reference to our opinion in the prospectus and proxy
statement to be issued pursuant to the Amended Agreement and to the inclusion of
the foregoing opinion in the prospectus and proxy statement relating to the
meeting of stockholders of Farwell. In giving such consent, we do not thereby
admit that we come within the category of persons whose consent is required
under Section 7 of the Securities Act of 1933 or the rules and regulations of
the Securities and Exchange Commission thereunder. Further, we express no view
as to the price or trading range for shares of the common stock of IBT following
the consummation of the Merger.

Based upon and subject to the foregoing, including the various assumptions and
limitations set forth herein, it is our opinion that, as of June 30, 2006, the
exchange ratio and cash consideration to be received by Farwell shareholders
under the Amended Agreement is fair, from a financial point of view, to the
shareholders of Farwell.

Very truly yours,



Donnelly Penman & Partners

                                   APPENDIX D

Section 3706(2)(b) of the Michigan Banking Code of 1999

          A shareholder of the existing bank, existing savings bank, or existing
association who votes against the consolidation, or who has given notice in
writing to that bank or association at or before the meeting called for the
purpose of considering the agreement of consolidation that the shareholder
dissents from the consolidation, is entitled to receive in cash from the
consolidated organization the fair value of all shares held by the shareholder,
if and when the consolidation is consummated, upon written request made to the
consolidated organization at any time within 30 days after the date of
consummation of the consolidation, accompanied by the surrender of the stock
voted in dissent by the shareholder. Upon the filing of the written request and
the surrender of stock certificates, if any, the shareholder shall cease to have
any of the rights of a shareholder except the right to be paid the fair value of
the shareholder's shares. The request having been made shall not be withdrawn
except with the written consent of the consolidated organization. The fair value
of the shares shall be determined, as of the date on which the meeting of
shareholders of the existing bank, existing savings bank, or existing
association was held adopting the agreement of consolidation, by a qualified and
independent appraiser selected by the commissioner upon written request
submitted by a dissenting shareholder entitled to receive the fair value of his
or her shares. The appraiser selected shall file a written appraisal with the
commissioner, who in turn shall forward copies to all interested parties. The
valuation determined by the appraiser is final and binding on all parties as to
the fair value of the shares. The consolidated organization shall pay to each
dissenting shareholder entitled the fair value of his or her shares within 30
days following the receipt of the written appraisal. The fees and expenses of
the appraisal, which shall be approved by the commissioner, shall be paid by the
consolidated organization. The agreement of consolidation shall provide the
manner of disposing of the shares of the existing bank, existing savings bank,
or existing association surrendered by the dissenting shareholders.

                 PART II. INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

The Articles of Incorporation of IBT provide that its directors and officers are
to be indemnified as of right to the fullest extent permitted under the Michigan
Business Corporation Act. Under the Michigan Business Corporation Act,
directors, officers, employees or agents are entitled to indemnification against
expenses (including attorneys' fees) whenever they successfully defend legal
proceedings brought against them by reason of the fact that they hold such a
position with the corporation. In addition, with respect to actions not brought
by or in the right of the corporation, indemnification is permitted under the
Michigan Business Corporation Act for expenses (including attorneys' fees),
judgments, fines, penalties and reasonable settlement if it is determined that
the person seeking indemnification acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
corporation or its shareholders and, with respect to criminal proceedings, he or
she had no reasonable cause to believe that his or her conduct was unlawful.
With respect to actions brought by or in the right of the corporation,
indemnification is permitted under the Michigan Business Corporation Act for
expenses (including attorneys' fees) and reasonable settlements, if it is
determined that the person seeking indemnification acted in good faith and in a
manner he or she reasonably believed to be in or not opposed to the best
interests of the corporation or its shareholders; provided, indemnification is
not permitted if the person is found liable to the corporation, unless the court
in which the action or suit was brought has determined that indemnification is
fair and reasonable in view of all the circumstances of the case.

In addition to the available indemnification, IBT's Articles of Incorporation,
as amended, limit the personal liability of the members of its Board of
Directors for monetary damages with respect to claims by IBT or its shareholders
resulting from certain negligent acts or omissions.

Under an insurance policy maintained by IBT, the directors and officers of IBT
are insured within the limits and subject to the limitations of the policy,
against certain expenses in connection with the defense of certain claims,
actions, suits or proceedings, and certain liabilities which might be imposed as
a result of such claims, action, suits or proceedings, which may be brought
against them by reason of being or having been such directors and officers.

ITEM 22. UNDERTAKINGS.

(a)  The undersigned registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

          (i) To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

          (ii) To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low end or high end
of the estimated maximum offering range may be reflected in the form of
prospectus filed with the Commission pursuant to Rule 424(b) if, in the
aggregate, the changes in volume and price represent no more than a 20 percent
change in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement;

          (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;"

     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (3) To remove form registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.


                                    Part II-2



     (4) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in the registration
statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

     (5) The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the proxy statement-prospectus, to each person to whom the proxy
statement-prospectus is sent or given, the latest annual report to security
holders that is incorporated by reference in the proxy statement-prospectus and
furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3
under the Securities Exchange Act of 1934.

     (6) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

     (7) The undersigned registrant undertakes that every prospectus: (i) that
is filed pursuant to the paragraph immediately preceding, or (ii) that purports
to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and
is used in connection with an offering of securities subject to Rule 415, shall
be filed as a part of an amendment to the registration statement and will not be
used until such amendment is effective, and that, for purposes of determining
any liability under the Securities Act of 1933, each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

     (8) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933 and will be governed by the
final adjudication of such issue.

(b)  The undersigned registrant hereby undertakes to respond to requests for
     information that is incorporated by reference into the prospectus pursuant
     to Item 4,10(b), 11 or 13 of this form, within one business day of receipt
     of such request, and to send the incorporated documents by first class mail
     or other equally prompt means. This includes information contained in
     documents filed subsequent to the effective date of the registration
     statement through the date of responding to the request.

(c)  The undersigned registrant hereby undertakes to supply by means of a
     post-effective amendment all information concerning a transaction, and the
     company being acquired involved therein, that was not the subject of and
     included in the registration statement when it became effective.


                                    Part II-3
