           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",  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
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 March 31, 2005 total assets  increased  $1.8  million to $677.7  million
from $675.9  million at December 31, 2004.  Asset  growth was  primarily  due an
increase of $9.3 million in federal funds sold offset by a $7.2 million decrease
in net loans.

     At March  31,2005,  securities  available  for sale  decreased  $300,000 to
$190.9  million  from  $191.2  million at  December  31,  2004.  This change was
primarily due to the  portfolio's  U.S.  Government  agencies and obligations of
state and  political  sub-divisions,  which posted net increases of $1.1 million
and $2.6  million,  respectively  offset by a net  decrease in  mortgaged-backed
securities of $4.0 million.

     Net loans  decreased  $7.2 million to $429.3 million at March 31, 2005 from
$436.5  million at December 31, 2004.  The net decreases  were primarily in real
estate  secured  mortgage and commercial  loans,  which dropped $5.0 million and
$2.5 million, respectively. This decrease is primarily due to loan pay-offs from
two large commercial borrowers.

     At March 31,  2005,  total  liabilities  increased  $2.2  million to $618.2
million from $616.0  million at December 31, 2004.  This  increase was primarily
the result of increases in repurchase  agreements and interest-bearing  deposits
of $4.3 million and $2.8 million, respectively offset by a $5.7 million decrease
in non-interest bearing deposits.

     Repurchase  agreements  increased to $19.5 million at March 31, 2005,  from
$15.2 million at December 31, 2004. The Company  offers its corporate  customers
sweep  accounts  where  unused  deposit  balances  are swept  into an  overnight
repurchase agreement yielding market rates.

                                       5


     Interest-bearing  deposits  increased to $441.8  million at March 31, 2005,
from $439.0  million at December  31,  2004.  The  increase of $2.8  million was
primarily due to a $10.6 million  increase in money market accounts offset by an
$8.0 million decrease in certificate of deposit accounts. Money market increases
are attributed to the offering of a new money market account.  The interest rate
paid and the  services  bundled  into this  deposit  product  have  impacted its
growth.

     Non-interest  bearing deposit accounts  decreased to $81.5 million at March
31, 2005,  from $87.2 million at December 31, 2004. The decrease of $5.7 million
is attributed to normal  fluctuations which arise due to the timing of month-end
pension and social security deposits.

     At March 31, 2005 total  stockholders'  equity decreased  $200,000 to $59.6
million from $59.8 million at December 31, 2004.  The decrease was primarily due
to  dividends  paid  of  $1.4  million  and  a  decrease  in  accumulated  other
comprehensive  income (net of deferred  income taxes) of $1.2 million  offset by
net income of $2.3 million.  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 March 31, 2005 decreased
$29,000,  or 1.2%, to  $2,324,000,  or $.78 per diluted  earnings per share from
$2,353,000,  or $.78 per diluted  earnings per share,  for the comparable  three
month period in 2004. The decrease for the three months ended March 31, 2005 was
primarily the result of increases in the loan loss provision, other expenses and
income tax expense offset by increases in net interest income and other income.

     INTEREST INCOME.  Interest income for the three months ended March 31, 2005
increased  $427,000 to $8,738,000 from $8,311,000 for the comparable three month
period in 2004. The average balance of interest  earning assets  increased $33.9
million for the three months ended March 31, 2005, to $634.9 million from $601.0
million for the comparable period in 2004, the yield on these assets decreased 3
basis points to 5.50%,  for the three months ended March 31, 2005 from 5.53% for
the  comparable  period in 2004.  The  on-going low  interest  rate  environment
continues  to put negative  pressure on interest  earning  assets.  See "Average
Balance Sheet and Rate/Volume Analysis"

     INTEREST  EXPENSE.  Interest  expense for the three  months ended March 31,
2005 increased  $275,000 to $3,127,000 from $2,852,000 for the comparable period
in 2004. The change in interest expense was primarily  attributed to an increase
of $34.9 million in the average balance of interest-bearing  liabilities and a 6
basis point  increase in the average cost of funds to 2.37% for the three months
ended March 31, 2005 from 2.31% for the comparable  period in 2004. See "Average
Balance Sheet and Rate/Volume Analysis"


                                       6


AVERAGE BALANCE SHEET

     The following table sets forth certain information  relating to the company
for the periods indicated.  The average yields and costs are derived by dividing
income or expense on an  annualized  basis by the  average  balance of assets or
liabilities,  respectively,  for the periods  presented.  Average  balances  are
derived from average daily balances.

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 months ended March 31, 2005
the  provision  for loan  losses  was  $300,000  compared  to  $125,000  for the
comparable 2004 period. Losses on several large loans during the last quarter of
2004 and the annual adjustment to the historical loss factors, which are used to
determine  the level of provision  needed,  contributed  to increased  loan loss
provision in 2005.

                                       8


     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
     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.

     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 March 31, 2005
increased  $277,000 to $1,625,000 from $1,348,000 for the comparable three month
period in 2004.  The  increase in other  income for the three months ended March
31, 2005 was  primarily  due to  increases  in service  fees and debit card fees
collected of $297,000 and $46,000, respectively offset by a decrease in security
gains of $103,000  from the  comparable  period in 2004. A growing  deposit base
supported the increased fees collected.  The change in security gains was due to
the sale of select  securities in 2004, that were expected to be called,  taking
advantage of the steep yield curve and reducing maturity concentrations.

     OTHER  EXPENSE.  Total other expense for the three month period ended March
31, 2005  increased  $60,000 to $3,710,000  from  $3,650,000  for the comparable
three month period in 2004. Salaries and data processing costs increased $77,000
and $16,000,  respectively at March 31, 2005 from the comparable  period in 2004
due to annual salary increases and third party

                                       9


processing  cost  increases.  Such  increases  were  offset  by  a  decrease  in
advertising  and other  expenses of $19,000 and $14,000,  respectively,  for the
comparable  periods.  The balance of the increase is due to normal  increases in
the cost of doing business.

     PROVISION  FOR INCOME  TAXES.  Income  taxes  increased to $902,000 for the
three month period ended March 31, 2005 from $678,000 for the comparable quarter
in 2004 as a  result  of  increases  in  taxable  income  due to a  decrease  in
deductions  available  for  income  taxes for  exercised  stock  options  and an
increase in the provision for loan losses.  Due to these factors,  the effective
tax  rate  increased  to 28% for the  first  quarter  of 2005  from  22% for the
comparable quarter in 2004.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     There were no significant changes for the three months ended March 31, 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.
