                                       AND
                           FARWELL STATE SAVINGS BANK
                    UNAUDITED PRO FORMA FINANCIAL INFORMATION

BASIS OF PRESENTATION

The following unaudited pro forma combined balance sheet and income statements
give effect to the merger. This pro forma financial information is based on the
historical consolidated financial statements of IBT Bancorp Inc. (IBT) and The
Farwell State Savings Bank (Farwell) under the assumptions, and including the
adjustments, set forth in the accompanying notes to unaudited pro forma combined
financial statements. The unaudited pro forma consolidated combined balance
sheet present combined financial information as of September 30, 2006, and the
unaudited pro forma consolidated combined statements of income presents combined
financial information for the nine month period ended September 30, 2006, and
for the year ended December 31, 2005. The unaudited pro forma consolidated
combined balance sheet assumes the merger was consummated on September 30, 2006,
and the unaudited pro forma consolidated combined statements of income give
effect to the merger as if the merger occurred at the beginning of each period
covered by such pro forma statements of income. Pro forma per share amounts are
based on total merger consideration of $145 per share of Farwell common stock.

IBT will account for the acquisition under the purchase method of accounting.
Accordingly, IBT will establish a new basis for Farwell's assets and liabilities
based upon the fair values thereof and the IBT purchase price, including direct
and incremental costs of the acquisition. The purchase accounting adjustments
made in connection with the development of the unaudited combined pro forma
financial statements are preliminary and have been made solely for the purpose
of developing such pro forma financial information and are based on the
assumptions described in the notes thereto.

The unaudited pro forma consolidated 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 that may be achieved with
respect to the combined businesses nor any adjustment to expenses for any future
operating changes. IBT may incur integration related expenses not reflected in
the pro forma financial statements, such as operational realignment. As a result
of this and other factors, the pro forma consolidated 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 nor of
the results that may be attained in the future. IBT is unaware of events that
would require a material change to the preliminary purchase price allocation.

NOTE 1 - PURCHASE PRICE ALLOCATION

On October 3, 2006, Farwell State Savings Bank (FSSB) merged with and into The
Farmers State Bank of Breckenridge (Farmers), a wholly owned subsidiary of IBT
Bancorp, Inc. (IBT) pursuant to the Amended and Restated Agreement and Plan of
Merger dated May 2, 2006 by and between FSSB, Farmers and IBT (the "Merger
Agreement"). Under the terms of the Merger Agreement, IBT issued an aggregate of
797,475 shares of its common stock and paid in cash a total of $7,612,000 to
FSSB shareholders.

The unaudited pro forma combined financial information gives effect to the
acquisition under the purchase method of accounting, and the unaudited combined
balance sheet assumes the transaction occurred on September 30, 2006 reflecting
the purchase consideration noted above.

NOTE 2 - PRO FORMA NOTES

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

          1)   Estimated fair values - The estimated fair value and resulting
               net premium on loans for purposes of these pro forma financial
               statements are being amortized to interest income over the
               remaining estimated lives of two years, using the level yield
               method.

          2)   The resulting adjustment to deposits 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.

Total                                              $1,047
                                                   ======


(D)  To record core deposit intangible created, which is $1,442 and is 3.9% of
     Farwell's non-contractual deposits. The core deposit intangible is assumed
     to be amortized on a 10 year sum of years' digits amortization schedule.

(E)  Elimination of Farwell's equity.
