                           FARWELL STATE SAVINGS BANK

DEAR SHAREHOLDER OF THE FARWELL STATE SAVINGS BANK:

     Due to a technical problem with respect to the notice for the September 12,
2006 Special Meeting of Shareholders, it was necessary for the Board of
Directors to reschedule the meeting from September 12, 2006 to September 26,
2006. You are cordially invited to attend the rescheduled special meeting of
shareholders of The Farwell State Savings Bank, to be held on September 26,
2006, at 10 a.m., local time, at the Surrey Township Hall, Farwell, Michigan. At
this special meeting, you will be asked to approve the acquisition of The
Farwell State Savings Bank by Farmers State Bank of Breckenridge, a wholly-owned
subsidiary of IBT Bancorp, Inc. The acquisition will be accomplished through the
merger of The Farwell State Savings Bank with and into Farmers State Bank of
Breckenridge.

     If the merger is completed as proposed, subject to certain possible
adjustments, each share of The Farwell State Savings Bank common stock will be
converted into the right to receive 3.0382 shares of IBT Bancorp, Inc. common
stock and $29.00 in cash. Cash will be paid in lieu of any fractional share of
IBT Bancorp, Inc. common stock.

     The last transaction price in IBT Bancorp, Inc. common stock known to
management occurring prior to the public announcement of the merger was $38.18 a
share on December 15, 2005, making 3.0382 shares of IBT Bancorp, Inc. common
stock and $29.00 in cash on that date equal to $145.00. The last transaction
price in IBT Bancorp, Inc. common stock known to management occurring prior to
the mailing of this Proxy Statement-Prospectus was $44 a share on August 15,
2006, making 3.0382 shares of IBT Bancorp, Inc. common stock and $29.00 in cash
equal on that date to $162.68.

     YOUR VOTE IS VERY IMPORTANT. The parties cannot complete the merger unless,
among other things, our shareholders approve the merger. THE FARWELL STATE
SAVINGS BANK BOARD OF DIRECTORS HAS APPROVED THE MERGER AND RECOMMENDS THAT YOU
VOTE "FOR" APPROVAL OF THE MERGER. Please review and consider this Proxy
Statement-Prospectus carefully.

     It is important that your shares are represented at the meeting, whether or
not you plan to attend. An abstention or failure to vote will have the same
effect as a vote against the merger. Accordingly, please complete, date, sign,
and return promptly your proxy card in the enclosed envelope. You may attend the
meeting and vote your shares in person if you wish, even if you have previously
returned your proxy.

                                        Sincerely,

                                        /s/ Thomas E. Kedrowski

                 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 32.

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
       (August 15, 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.

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


                                       ii



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.


                                       iii

     THE MERGER AGREEMENT IS ATTACHED TO THIS DOCUMENT AS APPENDIX A. WE

GOVERNS THE MERGER OF FARWELL WITH AND INTO FARMERS.

PARTIES TO THE MERGER

  WHAT FARWELL SHAREHOLDERS WILL RECEIVE IN THE MERGER (PAGE 14)

     If the Merger Agreement is approved and the merger is subsequently
completed, each outstanding share of Farwell common stock (other than 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.

  MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER (PAGE 32)

     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.

     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 32 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 15)

     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 16 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 August 18, 2006 and
the opinion of Donnelly Penman & Partners dated June 30, 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 12)

     Farwell will hold a special meeting of its shareholders on September 26,
2006 at 10:00 a.m., Michigan time, at the Surrey Township Hall, Farwell,
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, August 15,
2006. On that date, there were 262,500 shares of Farwell common stock

                                        2



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 12)

     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 35 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.

     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 26)

     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 31)

     We cannot complete the merger without the prior approval or non-objection
of the Federal Deposit Insurance Corporation ("FDIC") and the Michigan Office of
Financial and Insurance Services. The parties have received FDIC approval and
Farmers is in the process of seeking the other approvals and non-objections.
While we do not know of any reason why Farmers would not be able to obtain any
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 30)

     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 FDIC 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.


                                        3



     Other conditions to the completion of the merger are described beginning on
page 30. 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 31)

     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 31)

     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 36)

     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.

                        PRO FORMA MERGER DATA (UNAUDITED)

     The following table shows selected financial information of IBT on a pro
forma combined basis giving effect to the merger as if the merger had become
effective at the end of the period presented, in the case of balance sheet
information, and at the beginning of the period presented, in the case of income
statement information. The pro forma information reflects the purchase method of
accounting under accounting principles generally accepted in the United States
of America. These adjustments are preliminary and are subject to change. The
final adjustments will be calculated when the merger is effective and may be
materially different from those presented.

     The unaudited pro forma financial information is provided for informational
purposes only. The pro forma financial information presented is not necessarily
indicative of the actual results that would have been achieved by IBT had the
merger been consummated on the dates or at the beginning of the periods
presented, and is not necessarily indicative of future results.

      shares of IBT common stock, plus the payment of $7,612,500 in cash, in
      exchange for all of the outstanding shares of Farwell common stock. This
      assumes an exchange ratio of 3.0382 shares of IBT common stock and $29.00
      in cash for each share of Farwell common stock outstanding as of August
      15, 2006. The aggregate merger consideration to be paid by Farmers to all
      Farwell shareholders is subject to certain possible adjustments pursuant
      to the Merger Agreement.

                                 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.

                     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.

--------

  (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 85 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 September 12, 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 September 26, 2006 at 10:00 a.m., local time, at the Surrey
Township Hall, Farwell, 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.

     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 August 15, 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, 262,500 shares of
Farwell common stock were outstanding, and were held by approximately 120
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
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. These individuals have indicated that they will
vote "FOR" adoption of the Merger Agreement.


                                       12



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 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;

  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.

                                       14



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;

     - 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;


                                       15



     - 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.

  Opinions of Farwell's, Farmer's and IBT'S Financial Advisors

     The fairness opinions of the financial advisors, Austin Associates, LLC
("AAL") and Donnelly Penman & Partners ("Donnelly Penman") are described below.
The full text of the fairness opinions which set forth, among other things,
assumptions made, procedures followed, matters considered and limitations on the
review undertaken are attached to this document as Appendix B and C,
respectively. Shareholders of Farwell are urged to read the fairness opinions
carefully and in their entirety. To the extent that the descriptions contain
projections, estimates and/or other forward-looking statements about the future
earnings or other measures of the future performance of IBT, you should not rely
on any of these statements as having been made or adopted by IBT unless they
have been made by IBT in a document that is incorporated by reference into this
proxy statement-prospectus. See "Where You Can Find More Information."

  Austin Associates, LLC Opinion

     Farwell and IBT retained Austin Associates, LLC ("AAL") pursuant to an
engagement letter dated July 10, 2003 to provide financial advisory services in
connection with facilitating a potential business combination transaction under
which IBT would acquire Farwell. IBT and Farwell selected AAL based on its
experience, expertise and familiarity in representing community banks in similar
transactions. AAL is a nationally recognized investment banking firm and is
regularly engaged in the valuation of businesses and securities in connection
with mergers and acquisitions and valuations for corporate and other purposes.
AAL issued its written opinion dated August 18, 2006, that the financial terms
of the Merger Agreement are fair to each company and their respective
shareholders. AAL's written opinion is attached as Appendix B to this Proxy
Statement/Prospectus.

     You should consider the following when reading the discussion of AAL's
opinion in this document:

     - The summary of the AAL opinion set forth in this Proxy
       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.


                                       16



     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 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 August 18, 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.

--------

  (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:

     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:

     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.

     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.

     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.

     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 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     %

     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,

results of operations or material

                                       20



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.

     THE FULL TEXT OF THE OPINION OF DONNELLY PENMAN, WHICH SETS FORTH, AMONG
OTHER 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:

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

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

     - 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;

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


                                       21



     - 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;

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

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

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

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

     - 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;

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

     - 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.

     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

                                       22



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:

     Donnelly Penman also noted, when considering the most recent trading based
upon the closing price of IBT of $45.00 on June 28, 2006 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

                                       23



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:

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

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

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

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

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


                                       24



     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.

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:

     - 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;

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

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


                                       25



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

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

     - 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.

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.

     The parties expect that the merger will be effective during the third
quarter of 2006 or as soon as possible after the receipt of all regulatory and
shareholder approvals, the expiration of all regulatory waiting periods and
after the satisfaction of all conditions to the merger set forth in the Merger
Agreement.

DISTRIBUTION OF IBT COMMON STOCK

     At the effective time of the merger, Farwell's shareholders will cease to
own shares of Farwell. Subject to certain adjustments pursuant to the Merger
Agreement, each share of Farwell common stock issued and outstanding immediately
prior to the completion of the merger will automatically be converted into the
right to receive 3.0382 shares of IBT common stock and $29.00 in cash.

     At the effective time of the merger, IBT will deliver to its exchange
agent, Isabella Bank and Trust, the amount of cash and number of shares of IBT
common stock issuable in the merger. Within five business days after the closing
of the merger, the exchange agent will send you and other former Farwell
shareholders transmittal materials to be used to exchange the old Farwell stock
certificates. The transmittal materials will contain instructions with respect
to the surrender of old Farwell stock certificates. After the effective time of
the merger, and once the exchange agent receives your old Farwell stock
certificates, the exchange agent will send you a check for the cash payable in
exchange for your shares of Farwell common stock and will register the shares of
IBT common stock

                                       27



issuable to you in the name and at the address appearing on Farwell's stock
records as of the time of the merger or such other name or address as you
request in the transmittal materials. The exchange agent will not 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 certificate or certificates
and an indemnity bond), together with properly executed transmittal materials.
Such 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 course of business and to use reasonable efforts to preserve its
business organization and assets and maintain its rights and franchises. In
addition, Farwell has agreed that, except as expressly contemplated by the
Merger Agreement or specified in a schedule to the Merger Agreement, without the

       other than in the ordinary course of business;

     - purchase equity securities, or securities for its investment portfolio

       good repair; and

     - make any new loan or other credit facility commitment to any borrower or
       group of affiliated borrowers in excess of $250,000 for a construction
       loan, $500,000 for a commercial real estate loan, $250,000 for a
       commercial business loan or $500,000 for a residential loan, except for
       prior commitments previously disclosed to Farmers and for any loan in

       after being notified of the intent to make the loan.

     - sell or dispose of any assets or incur any liability other than in the
       ordinary course of business consistent with past practices and policies.

     In addition to these covenants, the Merger Agreement contains various other
customary covenants, including, among other things, access to information and
each party's efforts to cause its representations and warranties to be true and
correct on the closing date.

REPRESENTATIONS AND WARRANTIES

     The Merger Agreement contains a number of customary representations and
warranties by Farmers, IBT and Farwell regarding aspects of their respective

       the State of Michigan approves or provides its non-objection of the
       merger and all statutory waiting periods expire;

     - approval of the Merger Agreement by the affirmative vote of 66 2/3% of

     - Farmers and Farwell must have received a tax opinion from Foster, Swift,
       Collins & Smith, P.C. to the effect that the merger will qualify as a
       reorganization; and

     - None of the regulatory approvals shall impose any term, condition or
       restriction that Farmers or Farwell in good faith reasonably determines
       would so materially adversely affect the transaction as to render
       inadvisable in the reasonable good faith judgment of Farmers or Farwell,
       the consummation of the merger.

     - the representations and warranties made by Farmers and IBT in the Merger
       Agreement must be true and correct as of the closing date or to a

     - Farwell must have received a fairness opinion from Donnelly Penman &

       shareholders from a financial point of view.

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 FDIC 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
and has received approval of the merger from the FDIC. The merger cannot be
completed without such approvals and non-objections. Other than the FDIC
approval, 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 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.


                                       32



     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:

     - 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

                                       33



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.

     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

                                       34



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.

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.


                                       35



     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.

STOCK TRADING AND DIVIDEND INFORMATION

     There is no established public trading market for Farwell common stock. It
is Farwell's established practice to pay annual cash dividends. Farwell paid
cash dividends of $3.25 and $13.25 per share in 2003 and 2004, respectively, and
Farwell paid a cash dividend of $11.00 per share in 2005. As of August 15, 2006,
there were 262,500 shares of Farwell common stock issued and outstanding, and
approximately 120 shareholders of record.

GENERAL

     IBT is incorporated under the Michigan Business Corporation Act. Farwell is
incorporated under the predecessor to the Michigan Banking Code of 1999.
Accordingly, the rights of IBT shareholders are governed by the corporate laws
of the State of Michigan and the rights of Farwell shareholders are governed by
the banking laws of the State of Michigan. As a result of the merger, Farwell
shareholders will become shareholders of IBT. Thus, following the merger, the
rights of Farwell shareholders who become IBT shareholders in the merger will be
governed by the general corporate laws of the State of Michigan and by the IBT
articles of incorporation and bylaws. IBT's articles of incorporation and bylaws
will be unaltered by the merger.

                       COMPARISON OF SHAREHOLDERS' RIGHTS

     Set forth on the following pages is a summary comparison of the rights of
an IBT shareholder under the IBT articles of incorporation, the IBT bylaws, and
Michigan corporate law (right column) and the rights of a shareholder under the
Farwell Articles of Incorporation, the Farwell bylaws and Michigan banking law
(left column). The summary set forth below is not intended to provide a
comprehensive summary of Michigan corporate and banking

                                       36



law or of each company's governing documents. This summary is qualified in its
entirety by reference to the full text of the IBT articles of incorporation and
IBT bylaws, and the Farwell Charter and Farwell bylaws.

                                           corporations. The Control Share Act
                                           establishes procedures governing "control
                                           share acquisitions." A control share
                                           acquisition is defined as an acquisition
                                           of shares by an acquiror which, when
                                           combined with other shares held by that
                                           person or entity, would give the acquiror

                                           Under the Control Share Act, an acquiror
                                           may not vote "control shares" that were
                                           acquired in a control share acquisition

                                           Act does not affect the voting rights of
                                           shares owned by an acquiring person
                                           before the control share acquisition. The
                                           Control Share Act entitles corporations
                                           to redeem control shares from the
                                           acquiring person under certain
                                           circumstances. In other cases, the
                                           Control Share Act confers dissenters'
                                           rights upon all of a corporation's
                                           shareholders except the acquiring person.

corporate governance and rights of shareholders, that might discourage future
takeover attempts. As a result, shareholders who might desire to participate in
such transactions may not have an opportunity to do so. In addition, these
provisions will also render the removal of the Board of Directors or management
of IBT more difficult.

     The following description is a summary of the provisions of the articles of
incorporation and bylaws. See "Where You Can Find More Information" as to how to
review a copy of these documents.

     Restrictions on Call of Special Meetings.  The bylaws provide that special
meetings of shareholders can be called only by the President or the Secretary,
or by either of them on the request in writing or by vote of a majority of
directors or holders of at least a majority of the shares of capital stock of
IBT issued and outstanding.

     Prohibition of Cumulative Voting.  The articles of incorporation prohibit
cumulative voting for the election of directors.

     Authorized But Unissued Shares.  IBT has authorized but unissued shares of
common stock. See "Description of Capital Stock of IBT". The articles of
incorporation authorize ten million (10,000,000) shares of common stock, no par
value. As of July 18, 2006, there were 5,491,252 shares of IBT common stock
issued and outstanding.

articles of incorporation must be approved by 66 2/3% of the outstanding shares
of IBT's voting stock. The bylaws may be amended by a two-thirds vote of the
directors of IBT or the affirmative vote of a majority of shares in attendance
at a duly constituted meeting

                                       41

provisions of the bylaws requires the approval of holders of a majority of
outstanding shares.

     Classified Board of Directors.  The IBT Board of Directors is divided into
three classes, with the directors in each class being elected for a term of
three years.

     "for Cause" Removal of Directors.  Directors of IBT may be removed from
office at any time, but only for cause by the affirmative vote of the holders of
a majority of the shares of IBT common stock entitled to vote thereon.

                    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
"Where You Can Find More Information" on page 83.

                     BALANCE SHEETS AND STATEMENTS OF INCOME
                             (DOLLARS IN THOUSANDS)

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
     are being accreted to interest income over their remaining estimated lives
     of two years, using the level yield method.

          (2) The resulting adjustment on deposits and borrowings is being
     amortized to interest expense over the remaining estimated lives of two
     years.

  (B)

     The cash portion of the acquisition assumes funding through available cash
on deposit with affiliate banks. For purposes of this pro forma presentation, it
is assumed that the affiliated banks will offset the loss in deposits by
borrowing from established lines of credit.

  (C)

     Purchase accounting fair value adjustments are estimated as follows(1).

                      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

     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.

     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.

     The following schedules present the daily average amount outstanding for
each major category of interest earning assets, non-earning assets, interest
bearing liabilities, and non-interest bearing liabilities. This schedule also
presents an analysis of interest income and interest expense for the periods
indicated. All interest income is reported on a fully taxable equivalent (FTE)
basis using a 34% tax rate. Non-accruing loans, for the purpose of the following
computations, are included in the average loan amounts outstanding.

     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

                                       53



$44,000 and the provision for loans losses was zero. Management did not 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.

     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

     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.


                                       54



     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.

  DEPOSITS

     Deposits are the largest source of funds for financing asset growth. As
shown in 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.

     The following table shows the time periods and the amount of assets and

  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.

                          INDEPENDENT AUDITORS' REPORT

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. These financial statements are the responsibility of the
Company's management. 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.

                         THE FARWELL STATE SAVINGS BANK

                          NOTES TO FINANCIAL STATEMENTS
                             (DOLLARS IN THOUSANDS)

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 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.

                         THE FARWELL STATE SAVINGS BANK

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  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 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.


                                       69



                         THE FARWELL STATE SAVINGS BANK

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     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.

                         THE FARWELL STATE SAVINGS BANK

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     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 if classified as available for sale, no declines are
deemed to be other than temporary.

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

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

                                                             ----      ----

                                                                 

Unfunded commitments under lines of credit.................  $336      $609
Commitments to grant loans.................................   877       261
Commercial and standby letters of credit...................    53        50



     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.


                                       75



                         THE FARWELL STATE SAVINGS BANK

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     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.

     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.

                                  OTHER MATTERS

     As of the date of this document, Farwell's Board of Directors knows of no
matters that will be presented for consideration at its special meeting other
than as described in this document. However, if any other matter shall properly
come before this special meeting or any adjournment or postponement thereof and
shall be voted upon, the proposed proxy will be deemed to confer authority to
the individuals named as authorized therein to vote the shares represented by
the proxy as to any matters that fall within the purposes set forth in the
notice of special meeting.

FARWELL ANNUAL MEETING

     Farwell deferred scheduling its 2006 annual meeting of shareholders with
the impending special shareholders meeting and deems it to be in the best
interests of Farwell to continue to defer holding its 2006 annual meeting until
such special meeting of shareholders has occurred, after which the annual
meeting will be scheduled only if the Merger Agreement is not approved by the
requisite vote at the special meeting of the shareholders.

                       WHERE YOU CAN FIND MORE INFORMATION

     IBT has filed a registration statement on Form S-4 to register with the SEC
the offering of IBT common stock to be issued by IBT in the merger. This proxy
statement-prospectus is a part of that registration statement. As allowed by SEC
rules, this proxy statement-prospectus does not contain all of the information
contained in the registration statement or the exhibits to the registration
statement. This means that this proxy-statement prospectus

                           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 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.

     2.1.  Merger.  Subject to the terms and conditions of this Agreement, at
the Effective Time, FSSB shall merge with Farmers, with Farmers as the resulting
or surviving banking corporation (the "Surviving Corporation"). As part of the
Merger, each share of FSSB Common Stock shall be converted into the right to
receive the Merger Consideration pursuant to the terms of Article III hereof.

     2.2.  Closing; Effective Time.  Subject to the satisfaction or waiver of
all conditions to closing contained in Article IX hereof, the Closing shall
occur no later than five (5) business days following the latest to occur of (i)
the receipt of all required Regulatory Approvals, and the expiration of any
applicable waiting periods, (ii) the approval of the Merger by the shareholders
of FSSB, or (iii) at such other date or time upon which Farmers and FSSB
mutually agree (the "Closing"). The Merger shall be effected by the filing of a
certificate of merger with the Bureau on the day of the Closing (the "Closing
Date"), in accordance with Michigan Banking Law. The "Effective Time" means the
date and time upon which the certificate of merger is filed with the Bureau, or
as otherwise stated in the certificate of merger, in accordance with Michigan

     2.3.  Articles of Incorporation and Bylaws; Name.  The Articles of
Incorporation and Bylaws of Farmers as in effect immediately prior to the
Effective Time shall be the Articles of Incorporation and Bylaws of the
Surviving Corporation, until thereafter amended as provided therein and by

     2.4.  Directors and Officers of Surviving Corporation.  The board directors
of the Surviving Corporation shall consist of one of the incumbent directors of
each of FSSB and Farmers immediately preceding the Effective Time, the President
and CEO of IBT and two outside directors of IBT, each to hold office in
accordance with the Articles of Incorporation and Bylaws of the Surviving

Board of Directors a regional board to preserve the institutional knowledge of
FSSB immediately before the Merger and to provide advice to the IBT Board of
Directors about business and operations, community and customer needs in the
market area, regional economic conditions and such other advisory
responsibilities as determined by the IBT Board of Directors. The members of the
initial regional board shall consist of all incumbent members of the FSSB board

reorganization within the meaning of Section 368(a) of the Code and that this
Agreement shall constitute a "plan of reorganization" as that term is used in
Sections 354 and 361 of the Code. From and after the date of this Agreement and
until the Closing, each party hereto shall use its reasonable best efforts to
cause the Merger to qualify, and will not knowingly take any action, cause any
action to be taken, fail to take any action or cause any action to fail to be
taken which action or failure to act could prevent the Merger from qualifying as
a reorganization under Section 368(a) of the Code other than is contemplated by
this Agreement. Following the Closing, neither Farmers nor FSSB nor any of their
Affiliates shall knowingly take any action, cause any action to be taken, fail
to take any action or cause any action to fail to be taken, which action or
failure to act could cause the Merger to fail to qualify as a reorganization
under Section 368(a) of the Code.

     2.7.  Possible Alternative Structures.  Notwithstanding anything to the
contrary contained in this Agreement and subject to the satisfaction of the
conditions set forth in Article IX, prior to the Effective Time, Farmers shall,
with the consent of FSSB, which will not be unreasonably withheld, be entitled
to revise the structure of the Merger described in Section 2.1 hereof provided
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
in kind or value (or the composition thereof), or reduced in amount; and (iii)
such modification will not delay materially or jeopardize receipt of any
required Regulatory

                                       A-5



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 structure.

                       ARTICLE III -- CONVERSION OF SHARES

     3.1.  Conversion of FSSB Common Stock; Merger Consideration.  At the
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.

          (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.


                                       A-6



          (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 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.

     (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

                                       A-7



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.

     (h) Withholding. IBT or the Exchange  Agent will be entitled to deduct and
withhold from the consideration otherwise payable pursuant to this Agreement or
the transactions contemplated hereby to any holder of FSSB Common Stock such
amounts as IBT (or any Affiliate thereof) or the Exchange Agent are required to
deduct and withhold with respect to the making of such payment under the Code,
or any applicable provision of U.S. Federal, state, local or non-U.S. tax law.
To the extent that such amounts are properly withheld by IBT or the Exchange
Agent, such withheld amounts will be treated for all purposes of this Agreement
as having been paid to the holder of the FSSB Common Stock in respect of whom
such deduction and withholding were made and shall be delivered to the
applicable taxing authorities.

     3.3.  Reservation of Shares.  IBT shall reserve for issuance a sufficient
number of shares of IBT Common Stock for the purpose of issuing such shares to
FSSB shareholders in accordance with this Article III.

     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

     marketable title to all material assets and properties owned by FSSB or
     each FSSB Subsidiary 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 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 facilities or any transaction by
     FSSB acting in a fiduciary capacity, and (ii) statutory liens for amounts
     not yet delinquent or which are being contested in 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 maintain
     insurance considered by each of them to be reasonable for their respective
     operations. Neither FSSB nor any Significant Subsidiary of FSSB has
     received notice from any insurance carrier that (i) such insurance will be
     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 FSSB or any Significant Subsidiary of FSSB 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.

     (k) Legal Proceedings.  Except as set forth in FSSB Disclosure Schedule
4.1(k), neither FSSB nor any FSSB Subsidiary is a party to any, and there are no
pending or, to FSSB's Knowledge, threatened legal, administrative, arbitration
or other proceedings, claims (whether asserted or unasserted), actions or
governmental investigations or inquiries of any nature (i) against FSSB or any
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.


                                      A-12



     (l) Compliance With Applicable Law.

          (i) Except as set forth in FSSB Disclosure Schedule 4.1(l)(i), to
     FSSB's Knowledge, each of FSSB and each FSSB Subsidiary is in compliance in
     all material respects with all applicable federal, state, and local
     statutes, laws, regulations, ordinances, rules, judgments, orders or
     decrees applicable to it, its properties, assets and 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
     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 authority, orders and approvals are in full force and effect and, to the
     Knowledge of FSSB, no suspension or cancellation of any such permit,
     license, certificate, order or approval is threatened or will result from
     the 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 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.


                                      A-13



          (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 "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 (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.


                                      A-14



          (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.

          (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.


                                      A-15



     (o) Environmental Matters.

          (i) Except as may be set forth in FSSB Disclosure Schedule 4.1(o) and
     any Phase I Environmental Report identified therein, with respect to FSSB
     and each FSSB Subsidiary:

               (A) Each of FSSB and the FSSB Subsidiaries and, to FSSB's
          Knowledge, the Participation Facilities and Loan Properties are, and
          have been, in substantial compliance with, and are not liable under,
          any Environmental Laws;

               (B) FSSB has received no written notice that there is any suit,
          claim, action, demand, executive or administrative order, directive,
          investigation or proceeding pending and, to FSSB's Knowledge, no such
          action is threatened, before any court, governmental agency or other
          forum against it or any of the FSSB Subsidiaries or any Participation
          Facility (x) for 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 it or any of the FSSB Subsidiaries or any
          Participation Facility;

               (C) FSSB has received no notice that there is any suit, claim,
          action, demand, executive or administrative order, directive,
          investigation or proceeding pending and, to FSSB's Knowledge no such
          action is threatened, before any court, governmental agency or other
          forum relating to or against any Loan Property (or FSSB or any of the
          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
          operated by FSSB or any FSSB Subsidiary (including, without
          limitation, soil, groundwater or surface water on, or under the
          properties, and buildings thereon) 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
          request for information from any federal, state, local or foreign
          governmental 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 tanks
          on, in or under any properties owned or operated by FSSB or any of the
          FSSB Subsidiaries or any Participation Facility, and to FSSB's
          Knowledge, no underground storage tanks have been closed or removed
          from any properties owned or operated by FSSB or any of the FSSB
          Subsidiaries or any Participation Facility; and

          of the FSSB Subsidiaries' ownership or operation of any of their
          respective 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 by or release of Materials
          of Environmental Concerns in, on, under or affecting such properties
          that could reasonably be expected to result in material liability
          under the Environmental Laws. To FSSB's Knowledge, prior to the period
          of (x) FSSB's or any of the FSSB Subsidiaries' ownership or operation
          of any of their respective current properties or (y) FSSB's or any of

                                      A-16



     (p) Loan Portfolio.

          (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 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).


                                      A-17



     (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

     subject, in the case of any unaudited statements, to normal, recurring
     audit adjustments and the absence of footnotes.

of Code Section 1504(a). IBT has duly filed all federal, state and material

Farmers nor any Farmers Entity has received notice of, and to the Knowledge of
Farmers, there is no audit examination, deficiency assessment, tax investigation
or refund litigation with respect to any taxes of Farmers, IBT or any of its
Significant Subsidiaries, and no claim has been made by any authority in a
jurisdiction where Farmers, IBT or any of its Significant Subsidiaries do not
file tax returns that Farmers, IBT or any such Significant Subsidiary is subject
to taxation in that jurisdiction. Except as set forth in Farmers Entity
Disclosure Schedule 5.1(f), Farmers, IBT and its Significant Subsidiaries have
not executed an extension or waiver of any statute of limitations on the
assessment or collection of any material tax due that is currently in effect.
Farmers, IBT and each of its Significant Subsidiaries has withheld and paid all
taxes required to have been withheld and paid in connection with amounts paid or
owing to any employee, independent contractor, creditor, shareholder or other
third party, and Farmers, IBT and each of its Significant Subsidiaries, to the

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

                                      A-20



     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 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 legal,
administrative, arbitration or other proceedings, claims (whether asserted or
unasserted), actions or governmental investigations or inquiries of any nature
(i) against Farmers or any Farmers Entity, (ii) to which Farmers or 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.

     (j) Compliance with Applicable Law.

          (i) To the Knowledge of Farmers and IBT, each of Farmers and each
     Farmers Entity is in compliance in all material respects with all
     applicable federal, state, local and foreign statutes, laws, regulations,
     ordinances, rules, judgments, orders or decrees applicable to it, its
     properties, assets and 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 authority, orders and approvals are in full force and
     effect and, to the Knowledge of Farmers, no suspension or cancellation of
     any such permit, license, certificate, order or approval is threatened or
     will result from the consummation of the transactions contemplated by this
     Agreement, subject to obtaining the approvals set forth in Section 8.3.

          (iii) For the period beginning January 1, 2003, neither Farmers nor
     any Farmers Entity has received any written notification or, to the
     Knowledge of Farmers, any other communication from any Bank Regulator

                                      A-21



     (i) asserting that Farmers or any Farmers Entity is not 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 Regulatory Agreement. The most recent regulatory
     ratings given to Isabella Bank and Trust and Farmers as to compliance with
     the CRA is satisfactory or better.

Such reports and proxy materials complied, at the time filed with the SEC, in

     (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.

any material fact required to be stated therein or necessary to make the

the time of the meeting of shareholders of FSSB to be held in connection with
the Merger, contain any untrue statement of a material fact or omit to state any

     (s) Brokers, Finders and Financial Advisors.  Neither IBT, Farmers nor any
Farmers Entity, nor any of their respective officers, directors, employees or

     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 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

                                      A-23



     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 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.

representatives to confer with representatives of Farmers or a designated
Farmers Entity and report the general status of its ongoing operations at such
times as Farmers or a designated Farmers Entity may reasonably request. FSSB
will promptly notify Farmers or a designated Farmers Entity of any material
change in the normal course of its business or in the operation of its
properties and, to the extent permitted by applicable law, of any governmental
complaints, investigations or hearings (or communications indicating that the
same may be contemplated), or the institution or the threat of material
litigation involving FSSB or any FSSB Subsidiary.

     (b) Subject to Section 12.1 hereof, FSSB shall provide Farmers or a
designated Farmers Entity, within thirty (30) days after the end of each month,
a written list of (i) nonperforming assets (the term "nonperforming assets" for
purposes of this subsection, means loans that are "troubled debt restructuring"
as defined in Statement of Financial Accounting Standards No. 15, "Accounting by
Debtors and Creditors for Troubled Debt Restructuring,"), (ii) loans on
nonaccrual, (iii) real estate owned, (iv) all loans ninety (90) days or more

basis, FSSB shall provide Farmers or a designated Farmers Entity with a schedule
of all loan approvals, which schedule shall indicate the loan amount, loan type
and other material features of the loan.

     (c) FSSB shall promptly inform Farmers or a designated Farmers Entity upon
receiving notice of any legal, administrative, arbitration or other proceedings,
demands, notices, audits or investigations (by any federal, state or local
commission, agency or board) relating to the alleged liability of FSSB or any
FSSB Subsidiary under any labor or employment law.

     6.3.  Access to Properties and Records.  Subject to Section 12.1 hereof,

and shall request its auditors to provide Farmers or a designated Farmers Entity
with such historical financial information regarding it (and related audit
reports and consents) as Farmers or a designated Farmers Entity may request for
securities disclosure purposes. FSSB 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 audit" and a

                                      A-27



"phase II environmental audit" to be performed at any physical location owned or
occupied by FSSB or any FSSB Subsidiary. Farmers shall indemnify and hold

report of any Bank Regulator with respect to the condition or activities of FSSB
or any of the FSSB Subsidiaries.

Time, 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

which is necessary to correct any information in such FSSB Disclosure Schedule
which has been rendered materially inaccurate thereby.

     6.7.  Consents and Approvals of Third Parties.  FSSB shall use all
commercially reasonable efforts, and shall cause each FSSB Subsidiary to 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

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

                                      A-28



(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 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.

     6.12.  FSSB Audit for 2005.  FSSB's external audit for the year ending
December 31, 2005 shall be conducted by an auditor that is independent from FSSB
in accordance with Section 201 of the Sarbanes-Oxley Act of 2002 and the
regulations promulgated thereunder.

in the usual, regular and ordinary course consistent with past practices; use

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

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
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.

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

     7.6.  Employee Benefits.  Farmers and IBT shall, from and after the
Effective Time until January 1, 2008, continue the defined contribution plan of
FSSB in effect immediately preceding the Effective Time. Effective January 1,
2008, 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 of
Farmers. This Agreement shall not be construed to limit the ability of 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 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.

     7.7.  Access to Properties and Records.  Subject to Section 12.1 hereof,
Farmers and IBT shall permit FSSB access upon reasonable notice to their
properties, and shall disclose and make available to FSSB to the extent
permitted by applicable law during normal business hours all of its books,
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 independent
accountants and copies of all internal control reports submitted to IBT by such
accountants in connection with each annual, interim or special audit of the
books of IBT made by such accountants.


                                      A-30



     (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, including
without limitation, detailed monthly financial statements and loan 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,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.

     (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

                                      A-31



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.

or desirable (the "FSSB Shareholders Meeting"), (ii) in connection with the

the SEC, and each of FSSB and Farmers and the Farmers Entities shall mail an

prior to the date of the FSSB Shareholders Meeting, a written agreement, in the
form of Exhibit B hereto, providing that such person will not sell, pledge,

     Approval shall include any condition or requirement, excluding standard
     conditions that are normally imposed by the regulatory authorities in bank
     merger transactions, that would, in the good faith reasonable judgment of
     the Board of Directors of Farmers, materially and adversely affect the
     business, operations, financial condition, property or assets of the
     combined enterprise of FSSB and Farmers or otherwise materially impair the
     value of FSSB to Farmers and the Farmers Entities.

     accept such Superior Proposal; provided that FSSB shall not terminate this
     Agreement pursuant to this Section 11.1(i) and enter into a definitive
     agreement with respect to the Superior Proposal until the expiration of
     five (5) business days following Farmers' receipt of written notice
     advising Farmers that FSSB has received a Superior Proposal, specifying the
     material terms and conditions of such Superior Proposal (and including a
     copy thereof with all accompanying documentation, if in writing)
     identifying the person making the Superior Proposal and stating whether
     FSSB intends to enter into a definitive agreement with respect to the
     Superior Proposal. After providing such notice, FSSB shall provide a
     reasonable opportunity to Farmers during the five business-day period to
     make such adjustments in the terms and conditions of this Agreement as
     would enable FSSB to proceed with the Merger on such adjusted terms.

     11.2.  Effect of Termination.

     (a) In the event of termination of this Agreement pursuant to any provision
of Section 11.1, this Agreement shall forthwith become void and have no further
force, except that (i) the provisions of Sections 11.2, 12.1, 12.2, 12.6, 12.9,
12.10, and any other Section which, by its terms, relates to post-termination
rights or obligations, shall survive such termination of this Agreement and
remain in full force and effect.

     (b) If this Agreement is terminated, expenses and damages of the parties
hereto shall be determined as follows:

          (i) Except as provided below, whether or not the Merger is
     consummated, all costs and expenses incurred in connection with this
     Agreement and the transactions contemplated by this Agreement shall be paid
     by the

                                      A-36



     party incurring such expenses; provided, however, if the Merger is not
     consummated due to the failure to obtain any necessary Regulatory Approval,
     Farmers shall reimburse FSSB for its actual costs and expenses incurred by
     FSSB after March 9, 2006 in connection with this Agreement and the
     transactions contemplated by this Agreement including, without limitation,
     fees and expenses of its attorneys, accountants and financial advisors.

          (ii) In the event of a termination of this Agreement because of a
     willful breach of any representation, warranty, covenant or agreement
     contained in this Agreement, the breaching party shall remain liable for
     any and all damages, costs and expenses, including all reasonable
     attorneys' fees, sustained or incurred by the non-breaching party as a
     result thereof or in connection therewith or with respect to the
     enforcement of its rights hereunder.

     11.3.  Amendment, Extension and Waiver.  Subject to applicable law, at any
time prior to the Effective Time (whether before or after approval thereof by
the shareholders of FSSB), the parties hereto by action of their respective
Boards of Directors, may (a) amend this Agreement, (b) extend the time for the
performance of any of the obligations or other acts of any other party hereto,
(c) waive any inaccuracies in the representations and warranties contained
herein or in any document delivered pursuant hereto, or (d) waive compliance
with any of the agreements or conditions contained herein; provided, however,
that after any approval of this Agreement and the transactions contemplated
hereby by the shareholders of FSSB, there may not be, without further approval
of such shareholders, any amendment of this Agreement which reduces the amount
or value, or changes the form of, the Merger Consideration to be delivered to
FSSB's shareholders pursuant to this Agreement. This Agreement may not be
amended except by an instrument in writing signed on behalf of each of the
parties hereto. Any agreement on the part of a party hereto to any extension or
waiver shall be valid only if set forth in an instrument in writing signed on
behalf of such party, but such waiver or failure to insist on strict compliance
with such obligation, covenant, agreement or condition shall not operate as a
waiver of, or estoppel with respect to, any subsequent or other failure. Any
termination of this Agreement pursuant to Article XI may only be effected upon a
vote of a majority of the entire Board of Directors of the terminating party.

                          ARTICLE XII -- MISCELLANEOUS

     12.1.  Confidentiality.  Except as provided below, Farmers and FSSB each

     regulators, and financial advisers who are reasonably believed to have a
     need for such information in connection with the Merger.

          (b) No Other Use.  No party shall make any use, other than related to
     the Merger, of any information it may come to know as a direct result of a
     disclosure by the other party, its subsidiaries, directors, officers,
     employees, attorneys, accountants, or advisers or that may come into its
     possession from any other confidential source during the course of its
     investigation.

          (c) Excepted Information.  The provisions of this section shall not
     preclude the parties or their respective subsidiaries, from using or
     disclosing information that is readily ascertainable from public
     information or trade sources, known by it before the commencement of
     discussions between the parties or subsequently developed by it or its
     subsidiaries independent of any investigation under this Agreement,
     received from any other person who is not Affiliates with a party and who
     is not under any obligation to keep such information confidential, or
     reasonably required to be included in any filing or application required by
     any governmental or regulatory agency.

          (d) Prohibit Insider Trading.  The parties shall each take reasonable
     steps to assure that any person who receives nonpublic information
     concerning the Merger or the other party will treat the information
     confidentially as provided in this section and not directly or indirectly
     buy or sell, or advise or encourage other persons to buy or sell, FSSB
     Common Stock or IBT Common Stock until such information is properly
     disclosed to the public.

news release or other public announcement or communication has been mutually
agreed upon by the parties hereto.

     12.3.  Survival.  All representations, warranties and covenants in this
Agreement or in any instrument delivered pursuant hereto shall expire and be
terminated and extinguished at the Effective Time, except for those covenants

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.

     Based upon our analysis and subject to the qualifications described herein,
we believe that as of the date of this letter the terms of the Agreement are
fair, from a financial point of view, to IBT and Farwell and their respective
shareholders.

June 30, 2006

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 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, 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:

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

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

     - 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;

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

     - 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;

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

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

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

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


                                       C-1



     - 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;

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

     - 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,

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.
