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

     The Private  Securities  Litigation Reform Act of 1995 contains safe harbor
provisions regarding forward-looking  statements.  When used in this discussion,
the words "believes",  "anticipate",  "contemplates",  "expects",  "intends" and
similar expressions are intended to identify  forward-looking  statements.  Such
statements are subject to certain risks and uncertainties  which include changes
in interest rates, risks associated with the effect of opening new branches, the
ability to control  costs and expenses,  and general  economic  conditions.  IBT
Bancorp,   Inc.  undertakes  no  obligation  to  update  those   forward-looking
statements  to  reflect  events or  circumstances  after  the date  hereof or to
reflect the occurrence of unanticipated events.

GENERAL

     IBT  Bancorp,  Inc.  is a bank  holding  company  headquartered  in  Irwin,
Pennsylvania,  which  provides a full range of commercial and retail banking and
trust services through its wholly owned banking  subsidiary,  Irwin Bank & Trust
Co. (collectively, the "Company"). The Company's stock is traded on the American
Stock Exchange under the symbol IRW.

FINANCIAL CONDITION

     At  September  30,  2005 total  assets  increased  $18.7  million to $694.6
million from $675.9 million at December 31, 2004. Asset growth was primarily due
to net increases of $13.0 million in cash and cash  equivalents and $9.1 million
in  securities  available  for sale offset by net  decreases  of $1.4 million in
other  assets,  $769,000  in  Federal  Home  Loan Bank  stock,  and net loans of
$658,000.

     Securities  available  for sale reached  $200.3  million,  at September 30,
2005,  from  $191.2  million at December  31,  2004.  This  change is  primarily
attributed to net increases in U.S. Government agencies and obligations of state
and  political  sub-divisions  of $9.2 million and $7.5  million,  respectively,
offset by a net decrease in mortgage-backed  securities of $7.3 million.  During
the  quarter,  the  Company  sold low  yielding  U.S.  Government  agencies  and
mortgage-backed  security  pools,  owned at a premium,  of $4.0 million and $3.3
million, respectively, for a before tax loss of $138,000. The loss was offset by
the sale of obligations of state and political sub-divisions of $2.4 million for
a before tax gain of  $154,000.  The net yield the  Company  was  earning on the
investments  sold  was  4.41%.  The  Company  reinvested  in  a  combination  of
mortgage-backed  securities,  purchased at a discount,  and obligations of state
and  political  sub-divisions  with an  average  combined  yield of  5.30%.  The
improvement  in the yield  combined with the call  protection of the  discounted
mortgage-backed  securities  is intended to improve  the  structure  and overall
balance of the investment portfolio.

     Net loans  decreased  $658,000 to $435.9 million at September 30, 2005 from
$436.5  million at December 31, 2004.  The net decreases  were primarily in real
estate secured mortgage,  lines of credit,  and commercial loans, which declined
$2.3 million, $2.5 million, and $4.2 million, respectively,  offset by increases
in  consumer  installment  loans and  municipal  loans of $7.3  million and $2.7
million,  respectively. The decrease in real estate secured loans and commercial
loans is attributed to loan pay-

5


offs from two large commercial borrowers in the first quarter.

     At September 30, 2005, total liabilities  increased $16.7 million to $632.7
million from $616.0  million at December 31, 2004.  This  increase was primarily
due to an increase in repurchase  agreements of $23.5 million.  Offsetting  this
increase were  decreases in total deposits and FHLB advances of $5.8 million and
$1.2 million, respectively.

     Repurchase  agreements  increased to $38.7  million at September  30, 2005,
from $15.2  million at December 31, 2004.  This  increase is  attributed  to new
agreements with current deposit customers and customers with existing repurchase
agreements  temporarily  maintaining higher balances. The higher balances were a
result, in part, to tax collections  during the period,  which were subsequently
transferred out of the Company. The Company offers its corporate customers sweep
accounts  where unused deposit  balances are swept into an overnight  repurchase
agreement yielding market rates.

     Interest-bearing  deposits  decreased to $436.7  million at  September  30,
2005, from $439.0 million at December 31, 2004. The decrease of $2.3 million was
primarily  due to decreases in  certificate  of deposit and savings  accounts of
$7.0 million and $3.2  million,  respectively.  The change in time  deposits was
attributed to expected  deposit  reductions of local  municipalities  and school
districts.  This decrease was partially  offset by increases in money market and
interest-bearing   checking   accounts  of  $5.8   million  and  $2.0   million,
respectively.  The  growth  in  these  accounts  is  attributed  to new  product
offerings.

     Non-interest  bearing  deposit  accounts  decreased  to  $83.7  million  at
September  30, 2005,  from $87.2  million at December 31, 2004.  The decrease of
$3.5 million is attributed to deposits being swept into repurchase agreements.

     At September 30, 2005 total stockholders'  equity increased $2.1 million to
$61.9  million  from $59.8  million at  December  31,  2004.  The  increase  was
primarily  due to net income of $6.7 million  offset by  dividends  paid of $4.1
million  and a  decrease  in  accumulated  other  comprehensive  income  (net of
deferred  income  taxes) of $400,000.  Accumulated  other  comprehensive  income
decreased  as a  result  of  changes  in  the  net  unrealized  gains/losses  on
securities  available  for  sale.  Because  of  interest  rate  volatility,  the
Company's  accumulated other comprehensive income could materially fluctuate for
each  interim  period and  year-end.  See Note D to the  consolidated  financial
statements.

RESULTS OF OPERATIONS

     NET  INCOME.  Net income for the three  months  ended  September  30,  2005
decreased $123,000, or 5.7%, to $2,038,000,  or $.68 diluted earnings per share,
from  $2,161,000,  or $.72 diluted  earnings per share, for the comparable three
month period in 2004.  Net income for the nine months ended  September  30, 2005
increased $86,000,  or 1.3%, to $6,688,000,  or $2.24 diluted earnings per share
from  $6,602,000,  or $2.20 diluted  earnings per share, for the comparable nine
month period in 2004. The decrease for the three months ended September 30, 2005
was due to increases in other expenses and the provision for loan losses,  which
offset  improvements in net interest  income and other income.  The increase for
the nine months ended  September  30, 2005 was primarily the result of increases
in net interest  income and other income  offset by an increase in the provision
for loan loss and other expenses.

6


     INTEREST  INCOME.  Interest income for the three months ended September 30,
2005 increased  $615,000 to $9,016,000 from $8,401,000 for the comparable  three
month  period in 2004.  The  change in  interest  income was  attributed  to the
increase in the average balance of interest  earning assets of $16.8 million for
the three months ended September 30, 2005, to $645.2 million from $628.4 million
for the  comparable  period  in 2004  coupled  with the  yield  on these  assets
increasing  24 basis points for the three months ended  September  30, 2005,  to
5.59% from 5.35% for the comparable period in 2004. Interest income for the nine
months  ended  September  30, 2005  increased  $1,485,000  to  $26,569,000  from
$25,084,000  for the  comparable  nine  month  period in 2004.  This  change was
supported  by an  increase in the average  balance of interest  earning  assets,
which rose $24.6 million to $640.2  million for the nine months ended  September
30, 2005,  from $615.6 million for the  comparable  period in 2004. The yield on
the  interest  earning  assets  increased  10 basis points to 5.53% for the nine
months ended September 30, 2005,  from 5.43% for the comparable  period in 2004.
Although a flattening yield curve and rising  short-term rates have continued to
put pressure on net interest margins,  the Company's asset yields have benefited
from  increases in the prime rate.  See "Average  Balance Sheet and  Rate/Volume
Analysis"

     INTEREST EXPENSE. Interest expense for the three months ended September 30,
2005 increased  $546,000 to $3,516,000 from $2,970,000 for the comparable period
in 2004. The change in interest expense was primarily  attributed to an increase
of $11.3  million in the  average  balance of  interest-bearing  liabilities  to
$534.6  million from $523.3 million and a 36 basis point increase in the average
cost of funds to 2.63% for the three months ended  September 30, 2005 from 2.27%
for the comparable  period in 2004.  Interest  expense for the nine months ended
September 30, 2005 increased  $1,223,000 to $9,923,000  from  $8,700,000 for the
comparable  period  in 2004.  The  change  in  interest  expense  was  primarily
attributed  to  an  increase  of  $22.7  million  in  the  average   balance  of
interest-bearing  liabilities  to $531.0  million  from $508.3  million and a 21
basis point  increase in the average  cost of funds to 2.49% for the nine months
ended  September  30,  2005 from 2.28% for the  comparable  period in 2004.  See

RATE / VOLUME ANALYSIS

     The  following  table  shows the effect of changes in volumes  and rates on
interest  income  and  interest  expense.  The  changes in  interest  income and
interest  expense  attributable  to  changes  in both  volume and rate have been
allocated to the changes due to rate. Tax exempt income was not  recalculated on
a tax  equivalent  basis  due to the  immateriality  of the  change to the table
resulting from a recalculation.

         PROVISION  FOR  LOAN  LOSSES.  For the  three  and  nine  months  ended
September  30, 2005 the  provision  for loan losses was $300,000  and  $900,000,
respectively,  compared to $40,000 and $290,000 for the comparable 2004 periods.
The increase in the loan loss provision  reflects the historical loss experience
and recognition of the risk elements within the loan portfolio.

         The  provision  for loan losses is charged to  operations  to bring the
total  allowance for loan losses to a level that  represents  management's  best
estimate of the losses  inherent in the portfolio,  based on a monthly review by
management of the following factors:

o    Historical experience
o    Volume
o    Type of lending conducted by the Bank


10


o    Industry standards
o    The level and status of past due and non-performing loans
o    The general economic conditions in the Bank's lending area; and
o    Other factors affecting the collectability of the loans in the portfolio

     Large groups of homogeneous  loans, such as residential real estate,  small
commercial real estate loans and home equity and consumer loans are evaluated in
the aggregate  using  historical loss factors and other data. The amount of loss
reserve is calculated  using  historical loss rates, net of recoveries on a five
year rolling weighted average, adjusted for environmental, and other qualitative
factors such as industry, geographical,  economic and political factors that can
effect loss rates or loss measurements. Watch and classified loans are allocated
additional reserves.

     Large balance and/or more complex loans such as multi-family and commercial
real estate loans may be evaluated on an individual basis and are also evaluated
in  the  aggregate  to  determine  adequate  reserves.  As  specific  loans  are
determined to be impaired,  specific reserves are assigned based upon collateral
value,  market  value,  if  determinable,  or the present value of the estimated
future cash flows of the loan.

     The allowance is increased by a provision for loan loss which is charged to
expense,  and reduced by  charge-offs,  net of  recoveries.  Loans are placed on
non-accrual  status when they are 90 days past due,  unless they are  adequately
collateralized and in the process of collection.

         The allowance for loan losses is maintained at a level that  represents
management's best estimate of losses in the portfolio at the balance sheet date.
However,  there  can be no  assurance  that the  allowance  for  losses  will be
adequate to cover losses which may be realized in the future and that additional
provisions for losses will not be required.

     OTHER INCOME.  Total other income for the three months ended  September 30,
2005 increased  $368,000 to $1,638,000 from $1,270,000 for the comparable  three
month period in 2004. Total other income for the nine months ended September 30,
2005 increased  $1,086,000 to $5,041,000 from $3,955,000 for the comparable nine
month period in 2004. The increase in other income for the three and nine months
ended  September  30, 2005 was  primarily  due to  increases  in service fees of
$282,000 and $873,000,  respectively,  from the comparable  period in 2004. This
change was  primarily  due to  increased  fees  collected  on deposit  accounts.
Investment  security  gains  increased  $134,000  for  the  three  months  ended
September 30, 2005 from the comparable  period in 2004, offset by an increase in
investment  security losses of $119,000.  A one-time gain recorded from the sale
of  property  classified  as other real  estate,  included in other  income,  of
$231,000 was also recorded in the nine months ended September 30, 2005.

     OTHER  EXPENSES.  Total  other  expense for the three  month  period  ended
September 30, 2005  increased  $420,000 to $4,135,000  from  $3,715,000  for the
comparable  three month period in 2004.  Total other expenses for the nine month
period  ended  September  30,  2005  increased   $677,000  to  $11,909,000  from
$11,232,000.  Salaries costs  increased  $272,000 and $460,000 for the three and
nine month periods ended September 30, 2005,  respectively,  from the comparable
period in 2004 due to

11


increased  staffing  costs.  Increases in other  expenses for the three and nine
months ended September 30, 2005 were due to bank growth and normal  increases in
the cost of doing business.

     PROVISION  FOR INCOME TAXES.  The Company's  provision for income taxes for
the quarter ended September 30, 2005 was $666,000,  a $120,000  decline from the
prior year.  The decrease in tax expense was due to a lower  effective  tax rate
during  the 2005  period,  which  is  primarily  attributed  to an  increase  in
tax-exempt  interest  income.  The  effective  tax rates for the quarters  ended
September  30,  2005 and 2004 were 24.6% and 26.7%,  respectively.  For the nine
months ended  September 30, 2005,  the Company's  provision for income taxes was
$2,189,000  compared to $2,215,000 for the 2004 period. The Company's  effective
tax rates for the nine months ended  September  30, 2005 and 2004 were 24.7% and
25.1%, respectively.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     There  were no  significant  changes  for the three and nine  months  ended
September 30, 2005 from the  information  presented in the 10K statement,  under
the caption Market Risk, for the year ended December 31, 2004.

ITEM 4.  CONTROLS AND PROCEDURES

     The Company's management evaluated, with the participation of the Company's
Chief Executive  Officer and Chief Financial  Officer,  the effectiveness of the
Company's  disclosure  controls  and  procedures,  as of the  end of the  period
covered by this report.  Based on that evaluation,  the Chief Executive  Officer
and Chief Financial Officer concluded that the Company's disclosure controls and
procedures are effective to ensure that information  required to be disclosed by
the  Company  in the  reports  that it files or  submits  under  the  Securities
Exchange Act of 1934 is recorded, processed,  summarized and reported within the
time periods  specified in the  Securities and Exchange  Commission's  rules and
forms.

     There were no changes in the  Company's  internal  control  over  financial
reporting  that  occurred  during the  Company's  last fiscal  quarter that have
materially  affected,  or  are  reasonably  likely  to  materially  affect,  the
Company's internal control over financial reporting.
