PART I

Item 1. BUSINESS

General

  S&T Bancorp, Inc. ("S&T") was incorporated on March 17, 1983
under the laws of the Commonwealth of Pennsylvania as a bank holding
company and has two wholly owned subsidiaries, S&T Bank and S&T
Investment Company, Inc.  S&T is registered as a bank holding company
with the Board of Governors of the Federal Reserve System under the 
Bank Holding Company Act, as amended.

   As of December 31, 1998, S&T had $2.1 billion in total assets, 
$260 million in total shareholders' equity and $1.4 billion in 
total deposits.  Deposits are insured by the Federal Deposit 
Insurance Corporation ("FDIC") to the full extent provided by law.

   Total trust assets were approximately $649 million at December 
31, 1998.  Trust services include services as executor and trustee 
under wills and deeds, and as guardian and custodian of employee 
benefit trusts.

   S&T Bank is a full service bank with its Main Office at 800 
Philadelphia Street, Indiana, Pennsylvania, providing service to 
its customers through a branch network of 38 offices located in 
Armstrong, Allegheny, Indiana, Jefferson, Clarion, Clearfield and 
Westmoreland counties.

   S&T Bank's services include accepting time and demand deposit 
accounts, making secured and unsecured commercial and consumer 
loans, providing letters of credit, and offering discount brokerage 
services, personal financial planning and credit card services.  
S&T Bank has a relatively stable deposit base and no material amount
of deposits is obtained from a single depositor or group of depositors
(including federal, state and local governments).  S&T Bank does not 
experience significant fluctuations in deposits.

Employees

   As of December 31, 1998, S&T Bank had a total of 665 full-time 
equivalent employees.  S&T provides a variety of employment benefits
and considers its relationship with its employees to be good.

Supervision and Regulation

General

   S&T and S&T Bank are each extensively regulated under both 
federal and state law.  The following information describes 
certain aspects of that regulation applicable to S&T and S&T 
Bank and does not purport to be complete.  To the extent 
statutory or regulatory provisions or proposals are described, 
the description is qualified in its entirety by reference to the
particular statutory or regulatory provisions or proposals.

S&T

     As a bank holding company, S&T is subject to regulation under
the Bank Holding Company Act of 1956 ("BHCA") and the examination 
and reporting requirements of the Federal Reserve Board.  Under the 
BHCA, a bank holding company may not directly or indirectly acquire
ownership or control of more than five percent of the voting shares
or substantially all of the assets of any additional bank, or merge
or consolidate with another bank holding company, without the prior
approval of the Federal Reserve Board.

PAGE 2

Item 1. BUSINESS -- Continued

     The BHCA also generally limits the activities of a bank holding
company to that of banking, managing or controlling banks, or any 
other activity which is determined to be so closely related to banking 
or to managing or controlling banks as to be a proper incident thereto.
S&T is presently engaged in two nonbanking activities: S&T Investment 
Company, Inc., which is an investment holding company, and Commonwealth 
Trust Credit Life Insurance Company ("CTCLIC").  S&T Investment Company, 
Inc. was formed in June 1988 to hold and manage a group of investments 
previously owned by S&T Bank and to give S&T additional latitude to pur-
chase other investments.  CTCLIC, which is a joint venture with another 
financial institution, acts as a reinsurer of credit life, accident and 
health insurance policies sold by S&T Bank and the other institution.

     There are a number of obligations and restrictions imposed on 
bank holding companies and their depository institution subsidiaries
by federal law and regulatory policy that are designed to reduce 
potential loss exposure to the depositors of such depository 
institutions and to the FDIC insurance funds in the event the depository
institution becomes in danger of default or in default.  For example, 
under a policy of the Federal Reserve Board with respect to bank holding
company operations, a bank holding company is required to serve as a
source of financial strength to its subsidiary depository institutions 
and to commit resources to support such institutions in circumstances 
where it might not do so otherwise.

S&T Bank

     As a state-chartered commercial bank, the deposits of which 
are insured by the Bank Insurance Fund ("BIF") of the FDIC, S&T 
Bank is subject to the supervision and regulation of the 
Pennsylvania Department of Banking ("PADB") and the FDIC.  S&T 
Bank also is subject to various requirements and restrictions under
federal and state law, including requirements to maintain reserves 
against deposits, restrictions on the types, amount and terms and 
conditions of loans that may be granted, and limits on the type of 
other activities in which S&T Bank may engage and the investments 
it may make.  Various consumer and compliance laws and regulations 
also affect S&T Bank's operations.

     S&T Bank also is subject to federal laws that limit the amount 
of transactions between itself and S&T or S&T's nonbank subsidiaries.
Under these provisions, transactions by a bank subsidiary to its 
parent company or any nonbank affiliate generally are limited to 10% 
of the bank subsidiary's capital and surplus, or 20% in the aggregate.
Further, loans and extensions of credit generally are required to be 
secured by eligible collateral in specified amounts.  A bank, such as 
S&T Bank, is prohibited from purchasing any "low quality" asset from
an affiliate.  S&T Bank is in compliance with these provisions.

     As an FDIC-insured bank, S&T Bank also is subject to FDIC 
insurance assessments.  Currently, the amount of FDIC assessments 
paid by individual insured depository institutions ranges from zero 
to $.27 per $100 of insured deposits, based on their relative risk 
to the deposit insurance funds, as measured by the institutions' 
regulatory capital position and other supervisory factors.  S&T 
Bank currently pays the lowest premium rate based upon this risk 
assessment.  However, because legislation enacted in 1996 requires 
that all insured deposits pay a pro rata portion of the interest 
due on the obligations issued by the Financing Corporation, the 
FDIC is assessing BIF-insured deposits an additional $.013 per $100 
of deposits to cover those obligations.

Item 1. BUSINESS -- Continued

Capital

     The Federal Reserve Board and the FDIC have issued substantially 
similar risk-based and leverage capital guidelines applicable to 
banking organizations they supervise.  Under the risk-based capital 
requirements, S&T and S&T Bank each generally is required to maintain 
a minimum ratio of total capital to risk-weighted assets (including 
certain off-balance sheet activities, such as standby letters of 
credit), of eight percent.  At least half of the total capital is to 
be composed of common equity, retained earnings and qualifying 
perpetual preferred stock, less certain intangibles ("Tier 1 capital").
The remainder may consist of certain subordinated debt, certain hybrid 
capital instruments and other qualifying preferred stock, and a limited 
amount of the loan loss allowance ("Tier 2 capital") and, together with 
Tier 1 capital, ("Total capital").  At December 31, 1998, S&T's Tier 1 
and Total capital ratios were 14.18 percent and 17.09 percent, respectively,
and the ratios of Tier 1 capital and Total capital to total risk-adjusted 
assets for S&T Bank were 10.42 percent and 11.68 percent, respectively.

     In addition, each of the federal bank regulatory agencies has 
established minimum leverage capital ratio requirements for banking 
organizations.  These requirements provide for a minimum leverage 
ratio of Tier 1 capital to adjusted average quarterly assets equal 
to three percent for bank and bank holding companies that meet certain 
specified criteria, including that they have the highest regulatory 
rating and are not experiencing significant growth or expansion.  
All other banks and bank holding companies will generally be required 
to maintain a leverage ratio of at least 100 to 200 basis points above 
the stated minimum.  S&T's leverage ratio at December 31, 1998 was 
10.68 percent, and S&T Bank's leverage ratio was 7.48 percent.

     Both the Federal Reserve Board's and the FDIC's risk-based 
capital standards explicitly identify concentrations of credit risk 
and the risk arising from non-traditional activities, as well as an 
institution's ability to manage these risks, as important factors to 
be taken into account by the agency in assessing an institution's 
overall capital adequacy.  The capital guidelines also provide that 
an institution's exposure to a decline in the economic value of its 
capital due to changes in interest rates be considered by the agency 
as a factor in evaluating a bank's capital adequacy.  The Federal 
Reserve Board also has recently issued additional capital guidelines 
for certain bank holding companies that engage in trading activities.  
S&T does not believe that consideration of these additional factors 
will affect the regulators' assessment of S&T's or S&T Bank's capital 
position.

Payment of Dividends

     S&T is a legal entity separate and distinct from its banking 
and other subsidiaries.  A major portion of the revenues of S&T 
result from amounts paid as dividends to S&T by S&T Bank.  S&T Bank, 
in turn, is subject to state laws and regulations that limit the 
amount of dividends it can pay to S&T.  In addition, both S&T and
S&T Bank are subject to various general regulatory policies relating 
to the payment of dividends, including requirements to maintain 
adequate capital above regulatory minimums.  The Federal Reserve 
Board has indicated that banking organizations should generally pay 
dividends only if (1) the organization's net income available to
common shareholders over the past year has been sufficient to fund 
fully the dividends and (2) the prospective rate of earnings retention 
appears consistent with the organization's capital needs, asset quality 
and overall financial condition.  S&T does not expect that any of these 
laws, regulations or policies will materially impact its ability or the
ability of S&T Bank to pay dividends.  During the year ended December 
31, 1998, S&T Bank paid $17.5 million in cash dividends to S&T.

Item 1. BUSINESS -- Continued

Other Safety and Soundness Regulations

     The federal banking agencies possess broad powers under 
current federal law to take prompt corrective action to resolve 
problems of insured depository institutions.  The extent of 
these powers depends upon whether the institution in question 
is "well capitalized," "adequately capitalized," "undercapital-
ized," "significantly undercapitalized," or "critically under-
capitalized," as defined by the law.  As of December 31, 1998, 
S&T Bank was classified as "well capitalized."  The classific-
ation of depository institutions is primarily for the purpose of 
applying the federal banking agencies' prompt corrective action 
provisions and is not intended to be, and should not be interpreted 
as, a representation of overall financial condition or prospects 
of any financial institution.

     The agencies' prompt corrective action powers can include, 
among other things, requiring an insured depository institution 
to adopt a capital restoration plan which cannot be approved 
unless guaranteed by the institution's parent company; placing 
limits on asset growth and restrictions on activities, including 
restrictions on transactions with affiliates; restricting the 
interest rates the institution may pay on deposits; prohibiting 
the payment of principal or interest on subordinated debt; 
prohibiting the holding company from making capital distributions
without prior regulatory approval and, ultimately, appointing a 
receiver for the institution.  Among other things, only a "well 
capitalized" depository institution may accept brokered deposits 
without prior regulatory approval.

     The PADB also has broad enforcement powers over S&T Bank, 
including the power to impose fines and other civil and criminal 
penalties, and to appoint a conservator or receiver.

Interstate Banking and Branching

     The BHCA currently permits bank holding companies from any 
state to acquire banks and bank holding companies located in any 
other state, subject to certain conditions, including certain 
nation-wide and state-imposed concentration limits.  Effective 
June 1, 1997, S&T Bank has the ability, subject to certain
restrictions, including state opt-out provisions, to acquire 
by acquisition or merger, branches of banks located outside of 
Pennsylvania, its home state.  States may affirmatively opt-in 
to permit these transactions earlier, which Pennsylvania, among 
other states, has done.  The establishment of de novo interstate 
branches also will be possible in those states that expressly 
permit it.  Once a bank has established branches in a state through 
an interstate merger transaction, the bank may establish and acquire 
additional branches at any location in the state where a bank 
headquartered in that state could have established or acquired 
branches under applicable federal or state law.

Competition

     All phases of S&T Bank's business are highly competitive.  
S&T Bank's market area is western Pennsylvania, with a represent-
ation in Indiana, Armstrong, Allegheny, Jefferson, Clarion, 
Clearfield and Westmoreland counties.  S&T Bank competes with 
those local commercial banks which have branches and customer 
calling programs in its market area.  S&T Bank considers its 
major competitors to be First Commonwealth Bank headquartered in 
Indiana, PA; People's Bank headquartered in Ford City, PA; Indiana 
First Savings Bank headquartered in Indiana, PA; Clearfield Bank 
and Trust Company, headquartered in Clearfield, PA and Marion Center 
National Bank, headquartered in Marion Center, PA.  The proximity of 
Indiana to metropolitan Pittsburgh results in a significant impact 
on the S&T market because of media influence and penetration by 
larger financial institutions, such as Mellon Bank, National City 
Bank and PNC Bank.

Distribution of Assets, Liabilities and Shareholders' Equity; 
 Interest Rates and Interest Differential.

  The following discussion and analysis is presented so that 
shareholders may review in further detail the financial condition 
and results of operations of S&T.  This discussion and analysis 
should be read in conjunction with the consolidated financial 
statements, selected financial data and management's discussion 
and analysis incorporated by reference.  References to assets and 
liabilities and changes thereto represent daily average balances 
for the periods discussed, unless otherwise noted.

  Net interest income represents the difference between the 
interest and fees earned on interest-earning assets and the interest 
paid on interest-bearing liabilities.  Net interest income is 
affected by changes in the volume of interest-earning assets and 
interest-bearing liabilities and changes in interest yields and
rates.  Interest on loans to and obligations of state, municipal-
ities and other public entities is not subject to federal income tax.
As such, the stated (pre-tax) yield on these assets is lower than the 
yields on taxable assets of similar risk and maturity.  In order to 
make the pre-tax income and resultant yields comparable to taxable 
loans and investments, a taxable equivalent adjustment was added to 
interest income in the tables below.  This adjustment has been 
calculated using the U.S. federal statutory income tax rate of 35% 
for 1998, 1997 and 1996.  The following table demonstrates the amount 
that has been added to interest income per the summary of operations.

INFLATION AND CHANGING INTEREST RATES

   The majority of assets and liabilities of a financial 
institution are monetary in nature and therefore differ 
greatly from most commercial and industrial companies that 
have significant investments in fixed assets or inventory.
Fluctuations in interest rates and the efforts of the Federal 
Reserve Board to regulate money and credit conditions have a 
greater effect on a financial institution's profitability than 
do the effects of higher costs for goods and services.  Through
its asset/liability management committee ("ALCO"), S&T is 
positioned to cope with changing interest rates and inflationary 
trends.  ALCO monitors and manages interest rate sensitivity 
through gap, simulation and duration analysis.

   The schedule below presents S&T's interest rate sensitivity 
at December 31, 1998 using gap analysis.  The gap and cumulative 
gap represents the net position of assets and liabilities subject 
to repricing in specified time periods, as measured by a ratio of 
rate sensitive assets to rate sensitive liabilities.  ALCO policy 
guidelines for cumulative gap in the six and twelve month time 
frames, annually approved by the S&T Board of Directors, is 
currently a .85 to 1.15 range.  Management believes this range 
provides an acceptable and manageable level of interest rate 
risk for S&T.  Significant to gap analysis is the expected rate 
of asset prepayment, calls on securities and the behavior of 
depositors during periods of changing interest rates.  For 
example, in periods of declining interest rates, borrowers can 
be expected to accelerate loan prepayments and refinancings; 
depositors will tend to hold those certificates of deposits with 
rates currently higher than the market.  Conversely, in a rising 
interest rate scenario, borrower refinancings and prepayments 
typically decrease, while deposit shifting and early withdrawals 
tend to accelerate as depositors position funds to earn higher 
yields.

   ALCO continually monitors these historical behavior patterns 
through periods of changing interest rates, and uses this 
information to develop loan prepayments and decay rates for 
Core Deposits (demand, NOW, savings). The gap analysis below 
incorporates a flat rate scenario, and the following significant 
assumptions:

Monthly loan prepayments above contractual requirements
          
          5 year ARM - Commercial Real Estate                1.50 %
          Fixed Rate - Commercial Real Estate                1.25

</TABLE>

     S&T's six month and one year gap position at December 31, 
1998 is asset sensitive.  Asset sensitive means that more assets 
than liabilities of S&T will reprice during the measured time 
frames.  The implications of an asset sensitive position will 
differ depending upon the current trend of market interest rates.

     For example, an asset sensitive position in a declining 
interest rate environment, the yields on repricing assets can
theoretically be expected to decline more quickly than the cost 
of S&T repricing liabilities. This situation would cause a 
decrease to S&T's interest rate spreads, net interest income 
and to operating income.  Liquidity impacts in this scenario,
other than decreased yields, would not be material unless 
serious ongoing declines in operating results caused depositors,
lenders and investors to lose confidence.

     Conversely, an asset sensitive gap position in a rising 
interest rate scenario would theoretically have a positive impact
to interest rate spreads, net income and to operating income.  
Liquidity impacts would not be material in the short-term; in the 
long-term, improved operating income is always beneficial to 
liquidity issues.

     Gap analysis usefulness as a measurement of interest rate 
risk is limited because the time period measured is static.
Simulation provides a more dynamic modeling tool for interest 
rate risk since this technique can incorporate future assumptions 
about interest rates, volume fluctuations and customer behaviors.  
ALCO uses simulation to measure changes in net interest income 
during a 2%, plus or minus, change in current market interest rates 
(Rate Shock Analysis). Current ALCO policy guidelines require that 
declines in forecasted net interest income do not exceed 3% as a 
result of Rate Shock Analysis.

     Duration techniques are a relatively new addition to S&T's 
interest rate risk monitoring tools.  Duration modeling is
primarily used to assist in match fundings for large commercial 
loans, security purchases and segments of the installment loan 
portfolios.

Securities 

     S&T invests in various securities in order to provide 
a source of liquidity, increase net interest income and as 
an ALCO tool to quickly reposition the balance sheet for 
interest rate risk purposes.  Securities are subject to 
similar interest rate and credit risks as loans.  In addition, 
by their nature, securities classified as available for sale 
are also subject to market value risks that could negatively 
affect the level of liquidity available to S&T, as well as 
equity.

     Risks associated with various securities portfolios are 
managed and monitored by investment policies annually approved 
by the S&T Board of Directors, and administered through ALCO 
and the Chief Investment Officer.  As of December 31, 1998, 
management is not aware of any risk associated with securities
that would be expected to have a significant, negative effect 
to S&T's statement of condition or statement of operations.

</TABLE>


     At December 31, 1998, $2,933,000 of nonaccrual loans were secured.  
Interest income that would have been recorded under original terms 
totaled $337,000.  No interest income was recorded on these loans.  
It is S&T's policy to place loans on nonaccrual status when collection 
of interest or principal is doubtful, or generally when interest or 
principal are 90 days or more past due.  The accrual of interest on 
impaired loans is discontinued when, in management's opinion, the 
borrower may be unable to meet payments as they become due.  At 
December 31, 1998, there were no impaired loans that were on 
nonaccrual.  There are no foreign loan amounts required to be included 
in this table.  There were no restructured loans in the periods presented.

Summary of Loan Loss Experience

     Management evaluates the degree of loss exposure for loans on 
a continuous basis through a formal loan policy as administered by 
the Loan Administration Department and various management and director 
committees.  Problem loans are identified and continually monitored 
through detailed reviews of specific large dollar loans, and the 
analysis of delinquency and charge-off levels of consumer loan 
portfolios.  Charged-off and recovered loan amounts are applied to 
the allowance for loan losses.  Quarterly updates are presented to 
the S&T Board of Directors as to the status of loan quality.

     Additional amounts are added through a charge to current earnings 
through the provision for loan losses, based upon management's assess-
ment about the adequacy of the allowance for loan losses for probable 
loan losses.  A quantitative analysis is utilized to support the 
adequacy of the allowance for loan losses.  This analysis includes 
review of the high and low historical charge-off rates for loan 
categories, fluctuations and trends in the amount of classified loans 
and economic factors.  Economic factors consider the level of S&T's 
historical charge-offs that have occurrence within the credits economic 
life cycle.  Management also assesses other subjective factors such as 
economic conditions and business trends, concentrations, growth and 
composition of the loan portfolio and effectiveness of the Loan 
Administration Department.

    Significant to this analysis and assessment is the shift in 
loan portfolio composition to an increased mix of commercial loans.  
These loans are generally larger in size and due to our continuing 
growth, many are not well seasoned and could be more vulnerable to 
an economic slowdown.  Management relies on its risk rating process 
to monitor trends which may be occurring relative to commercial 
loans to assess potential weaknesses within specific credits.  
Current economic factors and trends in risk ratings are considered 
in the determination of the allowance for loan losses.

     This analysis and assessment results in an allowance for 
loan losses consisting of two components, allocated and unallocated.  
The allocated component of the allowance for loan losses reflects 
expected losses resulting from the analysis of individual loans 
developed through specific ratings and allocations, and historical 
loss experience for categories of loans.  The specific allocations 
are based upon regular analysis of loans and commitments over a fixed 
dollar amount and the internal credit rating for the loan or commit-
ment.  Categories of smaller individual loans are allocated based upon 
historical losses and current delinquency levels.

PAGE 14

Item 1. BUSINESS -- Continued

     The unallocated component is primarily subjective based 
upon management's assessment of nonquantifiable factors that
make historical trend analyses difficult:

          Economic factors
          Loan concentration in western Pennsylvania.
          Significant commercial loan volume increases in 
            the last three years in new markets with new customers.
          The introduction of several new consumer products.
          Increased commercial real estate lending.
          Recent increases in charged-off and impaired loans.
          Peer analysis.


     The allowance for loan losses in each of the years presented 
below considered management's assessment of the factors noted above, 
along with the growth in the loan portfolio.  The additions to the 
allowance charged to operating expense has maintained the allowance 
as a percent of loans at the following levels at the end of each
year presented.


                                Year Ended December 31

                   1998         1997       1996       1995       1994

     S&T has considered impaired loans in its determination of 
the allowance for loan losses. The allowance for loan losses for 
all impaired loans totaled $133,000 and $914,000 at December 31, 
1998 and 1997, respectively, and is included in the allowance 
allocated specifically to commercial loans.

     Asset quality is a major corporate objective at S&T.  
Based on the evaluation of loan quality and assessment of risk 
characteristics, management believes that the allowance for 
loan losses is adequate to absorb probable loan losses.

This table summarizes S&T's loan loss experience for each of 
the five years ended December 31:

           relation to its shareholders' equity or financial condition.

           known to be threatened or contemplated against S&T by

    may be elected to fill vacancies.  Vacancies in the Board of 
    Directors, including vacancies resulting from an increase in the
    number of directors, shall be filled only by a majority of the    
    remaining members of the Board of Directors, though less than a
    quorum, and each person so elected shall be a director until his or
    her successor is elected by the shareholders or until his or her
    earlier death, resignation or removal or disqualification from 
    office.  Notwithstanding anything contained in the Articles of 
    Incorporation or in the By-Laws of the Corporation to the contrary

follows:

authorized to issue 25,000,000 shares of common stock, $2.50 par
value per share, and 10,000,000 shares of preferred stock, without
par value ("Preferred Stock").

    Issuance and Designation of Shares of Preferred Stock.  The Board
of Directors of the Corporation is authorized, subject to limitaions
prescribed by law and the provisions of these Articles of Incorporation,
to provide for the issuance of the shares of Preferred Stock in series,
and by filing a statement with the Pennsylvania Department of State
pursuant to the applicable law of the Commonwealth of Pennsylvania, to 
establish from time to time the number of shares to be included in each
such series, and to fix the designation, powers, preferences and rights
of the shares of each such series and the qualificaitons, limitations or
restrictions thereof.

    The authority of the Board with respect to each series shall include,
but not be limited to, determination of the following:

    (a) The number of shares constituting that series and the distinctive
designation of that series;

    (b) The dividend rate on the shares of that series, whether dividends
shall be cumulative, and if so, from which date or dates, and the relative
rights of priority, if any, of payment of dividends on shares of that 
series;

    (c) Whether that series shall have voting rights, in addition to the
voting rights provided by law, and, if so, the terms of such voting rights;

    (d) Whether that series shall have conversion privileges, and, if so,
the terms and conditions of such conversion, including provision for 
adjustment of the conversion rate in such events as the Board of Directors
shall determine;

    (e) Whether or not the shares of that series shall be redeemable, and, 
if so, the terms and conditions of such redemption, including the date or
date upon or after which they shall be redeemable, and the amount per share
payable in case of redemption, which amount may vary under different 
conditions and at different redemption dates;

    (f) Whether that series shall have a sinking fund for the redemption or
purchase of shares of that series, and, if so, the terms and amount of such
sinking fund;

    (g) The rights of the shares of that series in the event of voluntary
or involuntary liquidation, dissolution or winding up of the corporation,
and the relative rights of priority, if any, of payment of shares of that
series; and
 
    (h) Any other relative rights, preferences and limitations of that
series.

    Dividends on Preferred Stock.  Dividends on outstanding shares of        
Preferred Stock shall be paid or declared and set apart for payment
before any dividends shall be paid or declared and set apart for payment 
on the common shares with respect to the same dividend period.

    Liquidation Distributions to Holders of Preferred Stock.  If upon 
any voluntary or involuntary liquidation, dissolution or winding up of
the Corporation, the assets available for distribution to holders of
shares of Preferred Stock of all series shall be insufficient to pay
such holders the full preferential amount to which they are entitled,
then such assets shall be distributed ratably among the shares of all
series of Preferred Stock in accordance with the respective preferential 
amounts (including unpaid cumulative dividends, if any) payable with
respect thereto.

ation, shall be amended to read as follows:

Management's Discussion and Analysis of 
Financial Condition and Results of Operations
S&T Bancorp, Inc. and Subsidiaries

Financial Condition

The $160.2 million growth of average earning assets in 1998 was 
primarily the result of an excellent lending year for S&T 
Bancorp, Inc. (S&T), combined with increases in the investment 
portfolio to maximize net interest income by taking advantage of 
low, short-term funding rates and investing in U.S. government 
agency securities. Average loan balances increased by $80.3 
million during 1998 and average securities and federal funds 
increased $79.9 million during 1998. The bulk of funding for this 
loan and security growth was provided by a $57.2 million increase 
in average deposits, a $12.9 million increase in average earnings 
retained and a $105.3 million increase in average borrowings.

</TABLE>

Lending Activity 

Total loans at December 31, 1998 were $1.4 billion, a $92.1 
million or 7.2% increase from December 31, 1997. Increases in 
average loans for 1998 and 1997 were $80.3 million and $103.5 
million, respectively. 
   
   Changes in the composition of the loan portfolio during 1998 
included increases of $129.6 million of commercial loans offset 
by decreases of $19.8 million of residential mortgages and a 
$17.7 million decrease in installment loans. Composition changes 
include decreases from the effects of $10.9 million of 1-4 family 
mortgage loans and $15.2 million of commercial loans that were 
sold or participated in 1998. 

   Commercial loans currently comprise 56% of the loan portfolio. 
Although commercial loans can be an area of higher risk, 
management believes these risks are properly managed by limiting 
the percentage amount of portfolio composition, a rigorous 
underwriting review by loan administration and the fact that many 
of the commercial loans are secured by real estate and are owner 
occupied.

   Residential mortgage lending continued to be a strategic focus 
for 1998 through the establishment of a centralized mortgage 
origination department, product redesign, secondary market 
activities and the utilization of commission compensated 
originators. Management believes that if a downturn in the local 
residential real estate market occurs, the impact of declining 
values on the residential real estate loan portfolio will be 
properly managed because of S&T's conservative mortgage lending 
policies for portfolio loans which generally require a maximum 
term of 20 years for fixed rate mortgages, and private mortgage 
insurance for loans with less than a 20% down payment. Adjustable 
rate mortgages with repricing terms of one, three and five years 
comprised 23% of the residential mortgage portfolio in 1998. 

   During the fourth quarter of 1997, S&T sold $12.7 million of 
long-term, lower-yielding 1-4 family mortgages, acquired from the 
Peoples Bank of Unity (Peoples) merger, to the Federal National 
Mortgage Association (FNMA). S&T retained the ongoing servicing 
rights on the mortgages sold and will originate 1-4 family 
mortgages in the future to be sold to FNMA. The rationale for 
these sales is to mitigate interest rate risk associated with 
holding long-term residential mortgages in the loan portfolio, to 
generate fee revenue from servicing, and still maintain the 
primary customer relationship. During 1998, S&T sold $10.9 
million of 1-4 family mortgages to FNMA. Fees and gains from 
mortgage servicing activities were $0.3 million in 1998. S&T will 
continue to sell longer-term loans to FNMA in the future on a 
selective basis, especially during periods of lower interest 
rates.

   Installment loan decreases are primarily associated with 
significantly lower volumes in the indirect auto loan category. 
During the fourth quarter of 1998, S&T exited the indirect 
automobile business. Pricing pressures were unusually intense in 
the indirect market during 1998 and 1997, and the decision was 
made to deploy investable funds and staff resources into other, 
higher yielding and lower risk earning assets. Installment loans 
have also decreased due to recent changes in government 
regulations which have significantly decreased the profit 
potential of guaranteed student loans. The remaining student loan 
portfolio of $7.0 million was sold in 1997. S&T will continue to 
distribute student loan applications for customer convenience, 
but will not fund or hold the loans. 

   Loan underwriting standards for S&T are established by a formal 
policy administered by the S&T Bank Credit Administration Department, 
and subject to the periodic review and approval of the S&T Bank 
Board of Directors.

PAGE 21

   Rates and terms for commercial real estate and equipment loans 
normally are negotiated, subject to such variables as economic 
conditions, marketability of collateral, credit history of the 
borrower and future cash flows. The loan to value policy 
guideline for commercial real estate loans is generally 75%.

   Residential, first lien, mortgage loan to value policy guideline 
is 80%. Higher loan to value loans can be approved with the 
appropriate private mortgage insurance coverage. Second lien 
positions are sometimes incurred with home equity loans, but 
normally only to the extent that the combined credit exposure for 
both first and second liens does not exceed 100% loan to value.

   A variety of unsecured and secured installment loan and credit 
card products are offered by S&T. However, the bulk of the 
consumer loan portfolio is automobile loans. Loan to value 
guidelines for direct loans are 90%-100% of invoice for new 
automobiles and 80-90% of "NADA" value for used automobiles. Loan 
to value policy guidelines for automobile loans purchased from 
dealers on a third-party basis were 90%-125% of invoice for new 
automobiles and 100%-125% of "Black Book" value for used 
automobiles. As noted previously, S&T exited the indirect 
automobile business in the fourth quarter of 1998 and will allow 
the remaining portfolio of $33.7 million to amortize through 
normal payments and payoffs.

   Management intends to continue to pursue quality loans in all 
lending categories within our market area in order to honor our 
commitment to provide the best service possible to our customers. 
S&T's loan portfolio primarily represents loans to businesses and 
consumers in our market area of western Pennsylvania rather than 
to borrowers in other areas of the country or to borrowers in 
other nations. S&T has not concentrated its lending activities in 
any industry or group. During the past several years, management 
has concentrated on building an effective credit and loan 
administration staff which assists management in evaluating loans 
before they are made and identifies problem loans early. 

Security Activity 

Average securities increased $83.8 million in 1998 and decreased 
$16.0 million in 1997. The 1998 increase is due to increasing the 
investment portfolio to maximize net interest income by taking 
advantage of low, short-term funding rates and investing in U.S. 
government agency securities, classified as available for sale. 
Interest rate risk associated with this strategy is managed and 
monitored through S&T's Asset Liability Committee (ALCO). The 
1997 decrease is attributable to utilizing funds from the 
maturities and sales of securities to fund loan growth and 
balance sheet repositioning activities following the Peoples 
merger. 

   The largest components of the 1998 increase included $98.9 
million of U.S. government agency securities, $3.4 million in 
other corporate securities, $3.5 million in corporate equities 
and $4.8 million in Federal Home Loan Bank (FHLB) stock. The FHLB 
stock is a membership and borrowing requirement. Offsetting these 
increases are decreases of $13.2 million in U.S. treasury 
securities, $0.2 million in mortgage-backed securities and $13.4 
million in tax-exempt state and municipal securities.

   During 1998, S&T sold $20.3 million of equity securities 
classified as available for sale. The sales were made in order to 
maximize returns when market opportunities are presented. 
Additionally, S&T may receive an exchange of shares relative to a 
merger; gains and losses are recognized on shares held of 
acquired institutions in accordance with Emerging Issues Task 
Force #91-5, Nonmonetary Exchange of Cost-Method Investments 
(EITF 91-5). The equity securities portfolio is primarily 
comprised of bank holding companies, as well as preferred and 
utility stocks to take advantage of the dividends received 
deduction for corporations. During 1998, the equity portfolio 
yielded 10.2% on a fully taxable equivalent basis and had 
unrealized gains at December 31, 1998, net of nominal unrealized 
losses, of $55.1 million.

   S&T's policy for security classification includes U.S. 
treasuries, U.S. government agencies, mortgage-backed securities 
and marketable equity securities as available for sale. Municipal 
securities and other corporate debt securities are classified as 
held to maturity. At December 31, 1998, unrealized gains, net of 
nominal unrealized losses, for securities classified as available 
for sale were approximately $61.5 million. 

Nonearning Assets 

Average nonearning assets increased $5.8 million in 1998 and $2.0 
million in 1997. The 1998 and 1997 increases can be primarily 
attributed to an increase in cash and due from and in accrued 
interest receivable on a higher earning asset balance. Cash and 
due from growth is primarily related to increased federal reserve 
requirements and check clearing balances resulting from demand 
deposit growth and higher level of cash management activities for 
customers.

Allowance for Loan Losses 

The year-end balance in the allowance for loan losses increased 
to $26.7 million or 1.95% of total loans at December 31, 1998 as 
compared to $20.4 million or 1.60% of total loans at December 31, 
1997.

</TABLE>

   The adequacy of the allowance for loan losses is determined by 
management through evaluation of the loss potential on individual 
nonperforming, delinquent and high-dollar loans; review of 
economic conditions and business trends; historical loss 
experience; and growth and composition of the loan portfolio, as 
well as other relevant factors.

   A quantitative analysis is utilized to support the adequacy of 
the allowance for loan losses. This analysis includes review of 
the high and low historical charge-off rates for loan categories, 
fluctuations and trends in the amount of classified loans and 
economic factors. Economic factors consider the level of S&T's 
historical charge-offs that have occurrence within the credits 
economic life cycle.

   Significant to this analysis is the shift in loan portfolio 
composition to an increased mix of commercial loans. These loans 
are generally larger in size and, due to our continuing growth, 
many are not well seasoned and could be more vulnerable to an 
economic slowdown. Management relies on its risk rating process 
to monitor trends which may be occurring relative to commercial 
loans to assess potential weaknesses within specific credits. 
Current economic factors and trends in risk ratings are 
considered in the determination of the allowance for loan losses.

   Net loan charge-offs totaled $4.3 million in 1998, including $2.0 
million related to a floor plan loan to an automobile dealership, 
compared to $3.3 million in 1997. The balance of nonperforming 
loans, which includes nonaccrual loans past due 90 days or more, 
at December 31, 1998, was $2.9 million or 0.21% of total loans. 
This compares to nonperforming loans of $3.6 million or 0.28% of 
total loans at December 31, 1997. 

   Asset quality is a major corporate objective at S&T, and 
management believes that the total allowance for loan losses is 
adequate to absorb probable loan losses. 

Deposits 

Average total deposits increased by $57.2 million in 1998 and 
$39.0 million in 1997. The mix of average deposits in 1998 
changed, with time deposits and money market accounts increasing 
$16.5 million and $31.5 million, respectively, while interest-
bearing demand and savings accounts decreased $12.9 million. 
Noninterest-bearing deposits increased by $22.1 million or 13.7% 
in 1998 and were approximately 14% and 13% of total deposits 
during 1998 and 1997, respectively. Some of the changes can be 
partially explained by strategic initiatives to increase demand 
accounts and cash management services. In addition, a new, 
successful strategy for money market account pricing was 
implemented in order to make these accounts more competitive with 
money funds offered at brokerage firms. In September 1998, S&T 
purchased a branch in Clarion, Pa. and assumed $39.0 million of 
deposits.

   Management believes that the S&T deposit base is stable and that 
S&T has the ability to attract new deposits, mitigating a funding 
dependency on volatile liabilities. Special rate deposits of 
$100,000 and over were 7% of total deposits during 1998 and 1997, 
respectively, and primarily represent deposit relationships with 
local customers in our market area. In addition, S&T has the 
ability to access both public and private markets to raise long-
term funding, if necessary. During 1995, S&T issued $25.0 million 
of retail certificates of deposit through two brokerage firms, 
further broadening the availability of reasonably priced funding 
sources. At December 31, 1998, there were $11.6 million of these 
brokered retail certificates of deposit outstanding. 

Borrowings 
   
Average borrowings increased $105.3 million in 1998 and were 
comprised of securities sold under repurchase agreements (REPOS), 
federal funds purchased and long-term borrowings at the FHLB. S&T 
defines REPOS with its retail customers as retail REPOS; 
wholesale REPOS are those transacted with other banks and 
brokerage firms with terms normally ranging from one to 14 days. 

   The average balance in retail REPOS increased approximately $9.1 
million for 1998 and decreased $11.3 million for 1997. The 1998 
increase is primarily attributable to new REPO sweep 
relationships in our cash management department. S&T views retail 
REPOS as a relatively stable source of funds since most of these 
accounts are with local, long-term customers. 

PAGE 23

   Wholesale REPOS and federal funds purchased averaged $87.1 
million in 1998, an increase of $34.1 million from the 1997 
averages. The aforementioned increase in the investment portfolio 
increased the usage of wholesale REPO fundings in 1998. 

   The interest rate risk of various funding strategies is managed 
through ALCO. During 1997, ALCO authorized three additional long-
term borrowings of $11.0 million at a fixed rate and $50.0 
million at an adjustable rate with the FHLB. At December 31, 
1998, S&T had long-term borrowings outstanding of $60.8 million 
at a fixed rate and $119.6 million at an adjustable rate with the 
FHLB. The purpose of these borrowings was to provide matched 
fundings for newly originated loans, to mitigate the risk 
associated with volatile liabilities, to take advantage of lower 
cost funds through the FHLB's Community Investment Program and to 
fund stock buy-backs. 

   Another ALCO strategy used to manage interest rate risk is the 
use of interest rate swaps. At December 31, 1998, S&T had 
notional values totaling $10.0 million in interest rate swaps. 
S&T pays a fixed rate of 5.3% on these instruments and receives a 
variable rate based upon the London Interbank Offer Rate. The 
purpose of these off-balance sheet arrangements is to lock-in 
funding costs of fixed rate loans.

Trust Assets 

The year-end market value balance of the S&T Bank trust 
department assets, which are not accounted for as part of the 
assets of S&T, increased 12% in 1998 and 24% in 1997. These 
increases were a result of management's effort to expand the 
marketing of trust products and services and general increases in 
the debt and equity markets during the periods.

Results of Operations
Year Ended December 31, 1998

Net Income 

Net income was a record $38.0 million or $1.35 per diluted 
earnings per share in 1998, representing a 15% increase from the 
$33.4 million or $1.17 per diluted earnings per share in 1997. 
The return on average assets increased to 1.90% for 1998, as 
compared to 1.84% for 1997. The return on average equity 
increased to 14.80% for 1998, compared to 13.71% for 1997. 
Increases to the net interest margin and other revenue 
contributed significantly to this enhanced earnings performance. 

Net Interest Income 

On a fully taxable equivalent basis, net interest income 
increased $3.2 million or 4% for 1998 compared to 1997. The net 
yield on interest-earning assets decreased to 4.61% in 1998 as 
compared to 4.85% in 1997. The decline in the net yield on 
interest-earning assets during 1998 was primarily attributed to 
the balance sheet growth with securities, as well as the Modified 
Dutch Tender Offer earlier this year that repurchased 
approximately 880,000 shares of S&T common stock. Net interest 
income was positively affected by $160.2 million or a 9% increase 
in average earning assets. 

   In 1998, average loans increased $80.3 million and average 
securities increased $83.8 million, comprising most of the 
earning asset growth. The yields on average loans increased by 
seven basis points and the yields on average securities declined 
30 basis points.

   Average interest-bearing deposits provided $57.2 million of the 
funds for the growth in average earning assets, at a cost of 
4.34% in 1998 as compared to 4.33% in 1997.

   Average increases of $106.7 million in REPOS and other borrowed 
funds provided additional funding. The cost of these funds 
decreased 15 basis points during 1998. During 1998, more longer-
term borrowings were utilized in order to mitigate interest rate 
risk.

   Also positively affecting net interest income was a $19.8 million 
increase to average net free funds. Average net free funds are 
the excess of demand deposits, other noninterest-bearing 
liabilities and shareholders' equity over nonearning assets.

   Maintaining consistent spreads between earning assets and costing 
liabilities is very significant to S&T's financial performance 
since net interest income comprised 86% of operating revenue. The 
level and mix of earning assets and funds is continually 
monitored by ALCO in order to mitigate the interest rate 
sensitivity and liquidity risks of the balance sheet. A variety 
of asset/liability management strategies were successfully 
implemented, within prescribed ALCO risk parameters, that enabled 
S&T to maintain a net interest margin consistent with historical 
levels.

Provision for Loan Losses 

The provision for loan losses is an amount added to the allowance 
against which loan losses are charged. The provision for loan 
losses was $10.6 million for 1998 compared to $5.0 million in 
1997. The provision expense and the adequacy of the allowance for 
loan losses is determined based upon management's assessment of 
economic conditions, credit quality statistics, loan 
administration effectiveness and other factors that would have an 
impact on probable losses in the loan portfolio. Also affecting 
the amount of provision expense is loan growth, portfolio 
composition and trends within risk ratings.

   Credit quality statistics are an important factor in determining 
the amount of provision expense. Net loan charge-offs totaled 
$4.3 million for 1998 compared to $3.3 million for 1997. Included 
in the charge-offs for 1998 is $2.0 million related to a floor 
plan loan to one automobile dealership. Nonperforming loans to 
total loans decreased to 0.21% at December 31, 1998.

   Also affecting the amount of provision expense is loan growth
and portfolio composition. Most of the loan growth in 1998 is 
attributable to larger-sized commercial loans.

Noninterest Income 

Noninterest income increased $8.0 million or 49% in 1998 compared 
to 1997. Increases included $0.5 million or 15% in trust income, 
$0.9 million or 21% in service charges and fees, a $1.3 million 
or 40% increase in other income and a $5.3 million or 97% 
increase in security gains. 

   The increase in trust income was attributable to bank-wide 
incentive programs and expanded marketing efforts designed to 
develop new trust business and to develop new relationships 
within the Allegheny County market.

   The increase in service charges on deposit accounts was primarily 
the result of management's continual effort to implement 
reasonable fees for services performed and to manage closely the 
collection of these fees, as well as the implementation of 
foreign ATM convenience fees in the fourth quarter of 1997.

   The increase in other income was a result of increased 
performance for brokerage and insurance commissions, letters of 
credit fees, covered calls, debit card commissions, and mortgage 
servicing income, as well as $0.4 million of nonrecurring gains 
recognized from oil and gas producing properties that were sold 
during the third quarter of 1998. These areas were the focus of 
several 1998 strategic initiatives and product enhancements 
implemented in order to expand this source of revenue. 

   S&T recognized $10.7 million of gains on equity securities during 
1998. Gains of $5.2 million were the result of EITF 91-5. This 
accounting pronouncement requires the mark to market of equity 
securities when an acquisition of the company in which securities 
are owned occurs. EITF 91-5 gains recognized included $2.6 
million from the First Union/Corestates merger, $0.4 million 
from the CFX/Peoples Heritage merger and $2.2 million from the 
First Commonwealth/Southwest merger. The remaining security gains 
were primarily attributable to the sale of equity securities in 
order to maximize returns by taking advantage of market 
opportunities when presented. 

Noninterest Expense 

Noninterest expense decreased $1.2 million or 3% in 1998 compared 
to 1997. The decrease is primarily attributable to $2.2 million 
of merger-related and other nonrecurring expenses associated with 
the acquisition of Peoples during 1997. Merger-related and other 
nonrecurring expenses included costs for severance and early 
retirement programs, the write-off and conversion of data 
processing systems, as well as legal, accounting and investment 
banker expenses. Other expenses of $0.9 million were provided for 
during 1998 and included $0.2 million of consulting fees for the 
redesigning of retail loan delivery services, $0.3 million for 
Year 2000 project costs and $0.3 million of costs associated with 
the conversion of data processing systems for a branch purchase. 

   Recurring expenses were relatively flat during 1998 as compared 
to 1997 and reflect normal activity increases. Severance and 
early retirement programs were implemented in May 1997 in order 
to eliminate duplicate positions following post-merger 
restructuring and consolidation of operations. Average full-time 
equivalent staff decreased from 665 to 659 in 1998. S&T's 
efficiency ratio, which measures noninterest expense as a percent 
of recurring noninterest income plus net interest income on a 
fully taxable equivalent basis, was 42% and 44% in 1998 and 1997, 
respectively. 

Federal Income Taxes 

Federal income tax expense increased $2.6 million to $16.2 
million in 1998 as a result of higher pretax income in 1998. The 
1998 effective tax rate of 30% was below the 35% statutory tax 
rate due to the tax benefits resulting from tax-exempt interest, 
excludable dividend income and the tax benefits associated with 
Low Income Housing Tax Credit (LIHTC) projects. S&T currently 
does not incur any alternative minimum tax.

Results of Operations
Year Ended December 31, 1997

Net Income 

Net income was a record $33.4 million or $1.17 per diluted 
earnings per share in 1997, representing a 17% increase from the 
$28.2 million or $1.00 per diluted earnings per share in 1996. 
The return on average assets increased to 1.84% for 1997, as 
compared to 1.65% for 1996. The return on average equity 
increased to 13.71% for 1997, compared to 13.01% for 1996. 
Increases to the net interest margin and other revenue 
contributed significantly to this enhanced earnings performance. 

Net Interest Income 

On a fully taxable equivalent basis, net interest income 
increased $4.8 million or 6% for 1997 compared to 1996. The net 
yield on interest-earning assets was essentially unchanged, 
increasing by two basis points to 4.85%. Net interest income was 
positively affected by the $91.1 million or 6% increase in 
average earning assets. 

   In 1997, average loans increased $103.5 million, offset by an 
average securities decrease of $16.0 million, comprising most of 
the earning asset growth. The yields on average loans increased 
by two basis points while the yields on average securities 
remained constant. 

   Average interest-bearing deposits provided $39.0 million of the 
funds for the growth in average loans, at a cost of 4.33%, 
relatively unchanged from 1996. The cost of REPOS and other 
borrowed funds increased 12 basis points during 1997. During 
1997, more longer-term borrowings were utilized in order to 
mitigate interest rate risk.

   Also positively affecting net interest income was a $33.1 million 
increase to average net free funds. Average net free funds are 
the excess of demand deposits, other noninterest-bearing 
liabilities and shareholders' equity over nonearning assets.

   Maintaining consistent spreads between earning assets and costing 
liabilities is very significant to S&T's financial performance 
since net interest income comprised 88% of operating revenue. The 
level and mix of earning assets and funds is continually 
monitored by ALCO in order to mitigate the interest rate 
sensitivity and liquidity risks of the balance sheet. A variety 
of asset/liability management strategies were successfully 
implemented, within prescribed ALCO risk parameters, that enabled 
S&T to maintain a net interest margin consistent with historical 
levels. 

Provision for Loan Losses 

The provision for loan losses is an amount added to the allowance 
against which loan losses are charged. The provision for loan 
losses was $5.0 million for 1997 compared to $5.2 million in 
1996. The provision expense is the result of management's 
assessment of economic conditions, credit quality statistics, 
loan administration effectiveness and other factors that would 
have an impact on probable losses in the loan portfolio. 

   Credit quality statistics are an important factor in determining 
the amount of provision expense. Net loan charge-offs totaled 
$3.3 million for 1997 compared to $3.5 million for 1996. 
Nonperforming loans to total loans decreased to 0.28% at December 
31, 1997.

   Also affecting the amount of provision expense is loan growth. 
Despite a $103.5 million or 9% increase in average loans, S&T's 
allowance for loan losses to total loans was 1.60% at December 
31, 1997, as compared to 1.56% at December 31, 1996.

Noninterest Income 

Noninterest income increased $4.4 million or 37% in 1997 compared 
to 1996. Increases included $0.3 million or 12% in trust income, 
$0.5 million or 14% in service charges and fees, a $0.2 million 
or 5% increase in other income and a $3.4 million or 147% 
increase in security and nonrecurring gains. 

   The increase in trust income was attributable to bank-wide 
incentive programs and expanded marketing efforts designed to 
develop new trust business and to develop new relationships 
within the Allegheny County market. The increase in service 
charges on deposit accounts was primarily the result of 
management's continual effort to implement reasonable fees for 
services performed and to manage closely the collection of these 
fees, as well as the implementation of foreign ATM convenience 
fees in the fourth quarter of 1997. The increase in other income 
was a result of increased performance for brokerage activities, 
letters of credit and fees on covered call options. These areas 
were the focus of several 1997 strategic initiatives and product 
enhancements implemented in order to expand this source of 
revenue. 

   Security and nonrecurring gains were primarily attributable to 
the sales of equity securities in order to maximize returns by 
taking advantage of market opportunities when presented. Also 
included is $0.5 million of gains related to the donation of 
appreciated equity securities to the S&T Charitable Foundation. 
Nonrecurring gains included $0.3 million of gains from student 
loan and residential mortgage loan sales. 

PAGE 26

Noninterest Expense 

Noninterest expense increased $0.8 million or 2% in 1997 compared 
to 1996. The increase is primarily attributable to increased 
employment, occupancy, data processing and other expenses 
associated with the acquisition of Peoples during the second 
quarter of 1997, offset by higher Federal Deposit Insurance 
Corporation (FDIC) insurance expense in 1996 relating to the one-
time surcharge on any financial institution holding Savings 
Association Insurance Fund (SAIF) deposits. S&T's efficiency 
ratio, which measures noninterest expense as a percent of 
recurring noninterest income plus net interest income on a fully 
taxable equivalent basis, was 44% and 48% in 1997 and 1996, 
respectively. 

   Staff expense increased 5% or $1.1 million in 1997. The increase 
resulted from normal merit increases, and costs for severance and 
early retirement programs related to the acquisition of Peoples 
that eliminated duplicate positions. Average full-time equivalent 
staff decreased from 677 to 665 in 1997. Severance and early 
retirement programs were implemented in May 1997.

   Occupancy and equipment expense, data processing and other 
expenses increased 4% or $0.7 million in 1997 as compared to 
1996. The increase is primarily attributable to a $0.8 million 
funding of S&T's Charitable Foundation, and to accounting, 
professional consulting and legal fees related to the acquisition 
of Peoples, offset by reduced FDIC insurance costs. The donation 
to the S&T Charitable Foundation will allow S&T to fund community 
contributions well into the future and help control future costs. 
Expense increases to occupancy, equipment, marketing and data 
processing include merger costs. Recurring costs and other 
charges were not significant and reflect normal activity 
increases, organization expansion and fee increases from vendors. 
Offsetting these costs was a $0.3 million reduction of goodwill 
amortization relating to a 1991 branch acquisition. 
   
   FDIC premium expense decreased by 80% during 1997 as a result of 
recapitalization legislation passed in September 1996. S&T Bank 
pays an annual premium of $.013 per $100 in Bank Insurance Fund 
(BIF) deposits and $.0648 per $100 on SAIF deposits, the lowest 
premium possible under the FDIC's risk assessment program for 
determining deposit insurance premiums. The SAIF fund was 
recapitalized by imposing a one-time surcharge of 65.6 basis 
points on any financial institution holding SAIF deposits. This 
surcharge resulted in an expense of $0.9 million during the third 
quarter of 1996. S&T Bank has $168.1 million of deposits subject 
to the SAIF. These deposits are related to a thrift institution 
and branches acquired from the Resolution Trust Corporation in 
1991. 

Federal Income Taxes 

Federal income tax expense increased $3.6 million to $13.6 
million in 1997 as a result of higher pretax income in 1997 and 
nondeductible merger related expenses. The 1997 effective tax 
rate of 29% was below the 35% statutory tax rate due to the tax 
benefits resulting from tax-exempt interest, excludable dividend 
income and the tax benefits associated with LIHTC projects. S&T 
currently does not incur any alternative minimum tax. 

Liquidity and Interest Rate Sensitivity

Liquidity refers to the ability to satisfy the financial needs of 
depositors who want to withdraw funds or borrowers needing access 
to funds to meet their credit needs. Interest rate sensitivity 
management seeks to avoid fluctuating net interest margins and to 
enhance net interest income through periods of changing interest 
rates. ALCO is responsible for establishing and monitoring the 
liquidity and interest rate sensitivity guidelines, procedures 
and policies. 

   The principal sources of asset liquidity are cash and due from 
banks, interest-earning deposits with banks, federal funds, 
investment securities that mature in one year or less and the 
market value of securities available for sale. At December 31, 
1998, the total of such assets was approximately $671.0 million 
or 32% of consolidated assets. However, liability liquidity is 
much more difficult to quantify, but is further enhanced by a 
stable core deposit base, access to credit lines at other 
financial institutions and S&T's ability to renew maturing 
deposits. Certificates of deposit in denominations of $100,000 or 
more represented 7% of deposits at December 31, 1998 and were 
outstanding primarily to local customers. S&T's ability to 
attract deposits and borrowed funds depends primarily on 
continued rate competitiveness, profitability, capitalization and 
overall financial condition. 
 
   Beyond the issue of having sufficient sources to fund unexpected 
credit demands or deposit withdrawals, liquidity management also 
is an important factor in monitoring and managing interest rate 
sensitivity issues through ALCO. Through forecast and simulation 
models, ALCO is also able to project future funding needs and 
develop strategies for acquiring funds at a reasonable cost.

   ALCO uses a variety of measurements to monitor the liquidity 
position of S&T. These include liquidity gap, net alternative 
funding resources, net loans to assets, net loans 

PAGE 27

to deposits, volatile liabilities and liquidity ratio. As of 
December 31, 1998, all of these measurements were in compliance 
with ALCO policy limitations.

   Because the assets and liabilities of S&T are primarily monetary 
in nature, the presentation and analysis of cash flows in formats 
prescribed by Financial Accounting Standards Board Statement No. 
95 "Statement of Cash Flows" (Statement No. 95), are less 
meaningful for managing bank liquidity than for other non-
financial companies. Funds are typically provided from current 
earnings, maturity and sales of securities available for sale, 
loan repayments, deposits and borrowings. The primary uses of 
funds include new loans, repayment of borrowings, the purchase of 
securities and dividends to shareholders. The level and mix of 
sources and uses of funds are constantly monitored and adjusted 
by ALCO in order to maintain credit, liquidity and interest rate 
risks within prescribed policy guidelines while maximizing 
earnings.

   ALCO monitors and manages interest rate sensitivity through gap, 
simulation and duration analyses in order to avoid unacceptable 
earnings fluctuations due to interest rate changes. S&T's gap 
model includes certain management assumptions based upon past 
experience and the expected behavior of customers during various 
interest rate scenarios. The assumptions include principal 
prepayments for mortgages, installment loans and mortgage-backed 
securities and classifying the demand, savings and money market 
balances by degree of interest rate sensitivity. Utilizing the 
above assumptions results in ratios of interest rate sensitive 
assets to interest rate sensitive liabilities for the six-month 
and 12-month intervals ended December 31, 1998 of 1.00% and 
1.07%, respectively. Assuming immediate repricings for interest-
bearing demand, savings and money market accounts, these ratios 
would be 0.72% and 0.85%, respectively. 

   In addition to the gap analysis, S&T performs an earnings 
sensitivity analysis to identify more dynamic interest rate risk 
exposures. The earnings simulation model is used to estimate the 
effect that specific interest rate changes would have on 12 
months of net interest income. Derivative financial instruments 
are included in this exercise. The model incorporates management 
assumptions regarding the level of interest rate or balance 
changes on indeterminate maturity deposit products (savings, 
money market, NOW and demand deposits) for a given level of 
market rate changes. These assumptions have been developed 
through a combination of historical analysis and future expected 
customer behavior. Interest rate caps and floors on all products 
are included to the extent that they become effective in the 12-
month simulation period. Additionally, changes in prepayment 
behavior of the residential mortgage portfolio in each rate 
environment are captured using management estimates. Finally, the 
impact of planned growth and anticipated new business activities 
is factored into the simulation model.
   
   S&T's policy objective is to limit the change in net interest 
income to 3% from an immediate and sustained parallel change in 
interest rates of 200 basis points. As of December 31, 1998 and 
1997, respectively, S&T had the following estimated earnings 
sensitivity profile:

Capital Resources 

Shareholders' equity increased $0.5 million at December 31, 1998 
compared to December 31, 1997. The primary source of equity 
growth for S&T is earnings retention. Hence, capital growth is a 
function of net income less dividends paid to shareholders and 
treasury stock activities. 

   Net income was $38.0 million and dividends declared to 
shareholders were $18.3 million for 1998. S&T paid 46% of 1998 
net income in dividends, equating to an annual dividend rate of 
$0.66 per share. The slight increase in capital is attributable 
to the conclusion of the Modified Dutch Auction in which S&T 
repurchased approximately 880,000 shares of its common stock. 
During 1998, S&T repurchased an additional 238,000 shares of its 
common stock. An authorization to buy back up to 1,000,000 
additional shares in 1999 was authorized by the S&T Board of 
Directors. Also affecting capital was a decrease of $0.6 million 
in unrealized gains on securities available for sale. 

   On September 21, 1998, the Board of Directors of S&T approved a 
two-for-one common stock split which was distributed in the form 
of a 100% stock dividend. 

PAGE 28

The new shares were distributed on October 30, 1998 to shareholders 
of record on October 15, 1998. The split increased the number of 
shares outstanding to 27,578,220.

   The book values of S&T's common stock increased 2% from $9.20 at 
December 31, 1997 to $9.38 at December 31, 1998, primarily due to 
the increase in shareholders' equity from retained earnings, offset 
by the slight decrease in unrealized holding gains on securities 
available for sale and by the aforementioned Modified Dutch Auction. 

   S&T continues to maintain a strong capital position with a 
leverage ratio of 10.7% as compared to the 1998 minimum 
regulatory guideline of 3%. S&T's risk-based capital Tier 1 and 
Total ratios were 14.2% and 17.1%, respectively, at December 31, 
1998, which places S&T well above the Federal Reserve Board's 
risk-based capital guidelines of 4% and 8% for Tier 1 and Total, 
respectively. Included in the total ratio is 45% of the pretax 
unrealized holding gains on available for sale equity securities 
as prescribed by banking regulations effective October 1, 1998. 
In addition, management believes that S&T has the ability to 
raise additional capital if necessary. S&T sponsored an ESOP. The 
ESOP shares were allocated to employees as part of S&T's 
contributions to its employee thrift and profit sharing plans. At 
December 31, 1998, the remaining unallocated shares held by the 
ESOP were allocated to employees as prescribed by the plan.

   In April 1993, shareholders approved the S&T Incentive Stock Plan 
authorizing the issuance of a maximum of 1,200,000 shares of 
S&T's common stock in order to assist in attracting and retaining 
employees of outstanding ability and to promote the 
identification of their interests with those of the shareholders 
of S&T. On October 17, 1994, the Stock Plan was amended to 
include outside directors. On April 21, 1997, shareholders 
approved an amendment to the plan increasing the number of 
authorized shares to 3,200,000. As of December 31, 1998, 
1,869,822 nonstatutory stock options had been granted to key 
employees and outside directors; 945,772 of these options are 
currently exercisable. 

Year 2000

The Year 2000 Issue is the result of computer programs having 
been written using two digits rather than four to define the 
applicable year. Any of S&T's computer programs or hardware that 
have date-sensitive software or embedded chips may recognize a 
date using "00" as the year 1900 rather than the year 2000. This 
could result in a system failure or miscalculations causing 
disruptions of operations, including, among other things, a 
temporary inability to process transactions, send invoices or 
engage in similar normal business activities.

   Based on recent assessments, S&T determined that it will be 
required to modify or replace some portions of hardware and 
software so that those systems will properly utilize dates beyond 
December 31, 1999. S&T presently believes that with modifications 
and replacement of existing hardware and software, the Year 2000 
Issue can be mitigated. However, if such modifications and 
replacements are not made, or are not completed timely, the Year 
2000 Issue could have a material impact on the operations of S&T.

   S&T's plan to resolve the Year 2000 Issue involves four phases: 
assessment, remediation, testing and implementation. In June 
1997, S&T management formed a task force (Y2K Task Force) to 
evaluate the process of preparing its computer systems and 
applications for the Year 2000. This process involves modifying 
or replacing certain hardware and software maintained by S&T, as 
well as communicating with external service providers and 
customers to ensure that they are taking the appropriate action 
to remedy their Year 2000 issues. To date, the Y2K Task Force has 
completed its assessment of the Year 2000 Issue with internal 
systems and third-party vendors. Assessment of the effect of the 
Year 2000 Issue on commercial business customers is still being 
evaluated.

   Significant to S&T's data processing abilities are the services 
provided by M&I Data Services (M&I) and Sungard Trust Services 
(Sungard) which provide the majority of computer services for S&T 
customer accounts and transactions. M&I and Sungard are also 
currently involved in a similar Year 2000 assessment and 
remediation. S&T converted to both M&I's and Sungard's Year 2000 
compliant software systems in the fourth quarter of 1998.

   All internal data processing systems are in the process of being 
tested for Year 2000 compliance. The testing also includes 
validations of third-party software/hardware vendors that have 
provided assurance or certifications of compliance. To date, 95% 
of the testing for critical systems has been completed and 
software/hardware replacements have been scheduled where problems 
have been identified. The testing is expected to be completed in 
the first quarter of 1999; the remediation of critical internal 
systems was completed by December 31, 1998.

   The effect of Year 2000 on the businesses of commercial customers 
is unknown and is currently being evaluated as part of this risk 
assessment process. The assessment identified 31 high-risk 
commercial customers as being significant to S&T's future 
financial performance. Each of these significant business 
customers are being called 

PAGE 29

upon and interviewed to determine their respective company's 
awareness and preparedness for the Year 2000 Issue. Results of 
these interviews are reported to the S&T Senior Loan Committee 
and credit administration so that remedial action can be taken 
when appropriate. Communications to all commercial customers 
via mail and calling officers has been ongoing to ensure 
effective planning to meet the Year 2000 compliance requirements.

   Management and the Y2K Task Force have completed substantially 
all of the critical systems and application changes by the end of 
1998 and believe that its level of preparedness is appropriate. 
S&T has also developed contingency plans for mission critical 
systems or applications which are either internal systems or 
services provided by external sources. These plans involve altern-
ative processing plans in the event of system or application 
failure. S&T expects to finalize these contingency plans during 
the first quarter of 1999. S&T has estimated the total cost of the 
project to be $0.3 million and is not expected to materially impact 
future operations. Purchased hardware and software will be capitalized 
in accordance with normal policy. Personnel and all other costs 
related to the project will be expensed as incurred. The Y2K Task 
Force reports to the S&T Board of Directors each quarter.

Regulatory Matters 

S&T and S&T Bank are subject to periodic examinations by one or 
more of the various regulatory agencies. During 1998, an 
examination was conducted by the Pennsylvania Department of 
Banking. This examination included, but was not limited to, 
procedures designed to review lending practices, credit quality, 
liquidity, operations and capital adequacy of S&T and its 
subsidiaries. No comments were received from the Pennsylvania 
Department of Banking which would have a material effect on S&T's 
liquidity, capital resources or operations. S&T's current capital 
position and results of regulatory examination allow it to pay 
the lowest possible rate for FDIC deposit insurance. 

Inflation 

Management is aware of the significant effect inflation has on 
interest rates and can have on financial performance. S&T's 
ability to cope with this is best determined by analyzing its 
capability to respond to changing interest rates and its ability 
to manage noninterest income and expense. S&T monitors its mix of 
interest rate sensitive assets and liabilities through ALCO in 
order to reduce the impact of inflation on net interest income. 
Management also controls the effects of inflation by reviewing 
the prices of its products and services, by introducing new 
products and services and by controlling overhead expenses. 

Business Uncertainties 

Due to the static economy in S&T's mature market area and the 
potential for decline, management believes that values of loan 
collateral and the ability of borrowers to repay could be 
adversely affected in an economic downturn. However, because of 
S&T's adequate allowance for loan losses, earnings strength and 
strong capitalization, as well as the strength of other 
businesses in our market area, management does not expect a 
decline in S&T's ability to satisfactorily perform if further 
decline in our economy occurs. In addition, S&T's recent 
acquisitions provide expanded market opportunities in areas with 
better growth potential.

Notes to Consolidated Financial Statements
S&T Bancorp, Inc. and Subsidiaries

Note A

Accounting Policies

The financial statements of S&T Bancorp, Inc. and 
subsidiaries (S&T) have been prepared in accordance with 
generally accepted accounting principles. In preparing the 
financial statements, 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 revenues and 
expenses for the period. Actual results could differ from those 
estimates. The more significant accounting policies are described 
below.

Principles of Consolidation

The consolidated financial statements include the accounts of S&T 
and its subsidiaries. All significant intercompany transactions 
have been eliminated in consolidation. The investment in the 
subsidiaries is carried at S&T's equity in the underlying net 
assets. The 1996 financial information has been restated to 
reflect the merger of Peoples Bank of Unity on May 2, 1997.

Securities

Management determines the appropriate classification of 
securities at the time of purchase. If management has the 
positive intent and S&T has the ability at the time of purchase 
to hold securities until maturity, they are classified as held to 
maturity and are stated at cost adjusted for amortization of 
premiums and accretion of discounts. All obligations of states 
and political subdivisions and corporate securities are 
classified in this category. Securities to be held for indefinite 
periods of time are classified as available for sale and are 
recorded at market value. All U.S. treasury securities, U.S. 
government corporations and agencies, mortgage-backed securities, 
and marketable equity securities are classified in this category. 
Gains or losses on the disposition of securities are based on the 
specific identification method. S&T does not engage in any 
securities trading activity.

Loans

Interest on loans is accrued and credited to operations based on 
the principal amount outstanding. Accretion of discount on loans 
is included in interest income. Loan origination fees and direct 
loan origination costs are deferred and amortized as an 
adjustment of loan yield over the respective lives of the loans. 
Loans are placed on nonaccrual and interest is discontinued when 
collection of interest or principal is doubtful, or generally 
when interest or principal are 90 days or more past due. 

   Impaired loans are defined by management as commercial and 
commercial real estate loans for which it is probable that the 
Bank will not be able to collect all amounts due according to the 
contractual terms of the loan agreement. Residential real estate 
mortgages and consumer installment loans are large groups of 
smaller balance homogeneous loans and are separately measured for 
impairment collectability. Factors considered by management in 
determining impairment include payment status and underlying 
collateral value. All impaired loans are classified as 
substandard for risk classification purposes. Impaired loans are 
charged-off, to the estimated value of collateral associated with 
the loan, when management believes principal and interest are 
deemed uncollectible. The accrual of interest on impaired loans 
is discontinued when, in management's opinion, the borrower may 
be unable to meet the payments as they become due. When interest 
accrual is discontinued, all unpaid accrued interest is reversed. 
Interest income is subsequently recognized only to the extent 
that cash payments are received.

   The allowance for loan losses is established through provisions 
for loan losses charged against income. Loans considered to be 
uncollectible are charged against the allowance, and recoveries, 
if any, are credited to the allowance. The allowance for loan 
losses is maintained at a level believed adequate by management 
to absorb probable losses in the loan portfolio. Management's 
determination of the adequacy of the allowance is based on 
periodic evaluations of the loan portfolio, past loan loss 
experience, current economic conditions, volume, growth and 
composition of the loan portfolio and other relevant factors.

Premises and Equipment

Premises and equipment are stated at cost less accumulated 
depreciation. The provision for depreciation is computed 
generally by the straight-line method for financial reporting 
purposes and by accelerated methods for federal income tax 
purposes.

Other Real Estate

Other real estate is included in other assets and is comprised of 
properties acquired through foreclosure proceedings or acceptance 
of a deed in lieu of foreclosure and loans classified as in-
substance foreclosure. These properties are carried at the lower 
of cost or fair value less cost of resale. Loan losses arising 
from the acquisition of such property are charged against the 
allowance for loan losses. Gains or losses realized subsequent to 
acquisition are recorded in the results of operations.

PAGE 35

Income Taxes

Deferred tax assets and liabilities are reflected at currently 
enacted income tax rates applicable to the period in which the 
deferred tax assets or liabilities are expected to be realized or 
settled.

Trust Assets and Income

Assets held in a fiduciary capacity by the Bank are not assets of 
the Bank and are therefore not included in the consolidated 
financial statements. Trust fee income is reported on the accrual 
basis.

Pensions

Pension expense for the Bank's defined benefit pension plan is 
actuarially determined using the projected unit credit actuarial 
cost method. The funding policy for the plan is to contribute 
amounts to the plan sufficient to meet the minimum funding 
requirements of the Employee Retirement Income Security Act of 
1974, plus such additional amounts as may be appropriate, subject 
to federal income tax limitations.

Treasury Stock

The purchase of S&T common stock is recorded at cost. At the time 
of reissue, the treasury stock account is reduced using the 
average cost method.

Earnings Per Share

Financial Accounting Standards Board Statement No. 128, "Earnings 
Per Share" (Statement No. 128), was effective in 1997 and 
provides a simpler calculation called basic Earnings Per Share 
(EPS) which replaces primary EPS under APB Opinion 15. Basic EPS 
is calculated by dividing income available to common shareholders 
by the weighted average number of common shares outstanding 
during the period. Options, warrants and other potentially 
dilutive securities are excluded from the basic calculation, but 
are included in diluted EPS. All prior periods have been restated 
and recorded in accordance with Statement No. 128.

   Average shares outstanding for computing basic EPS were 
27,762,801, 28,263,036 and 28,217,234 for 1998, 1997 and 1996, 
respectively. Average shares outstanding for computing dilutive 
EPS were 28,055,142, 28,618,364 and 28,440,844 for 1998, 1997 and 
1996, respectively. In computing dilutive EPS, average shares 
outstanding have been increased by the common stock equivalents 
relating to S&T's available stock options.

Per Share Amounts

Prior years net income and dividends per share amounts have been 
restated to reflect the two-for-one common stock split in the 
form of a 100% stock dividend distributed on October 30, 1998.

Cash Flow Information

S&T considers cash and due from banks as cash and cash 
equivalents. For the years ended December 31, 1998, 1997 and 
1996, cash paid for interest was $69,295,000, $60,825,000 and 
$58,860,000, respectively. Cash paid during 1998 for income taxes 
was $15,567,000 compared to $14,190,000 for 1997 and $11,014,000 
for 1996.

Comprehensive Income

Financial Accounting Standards Board Statement No. 130, 
"Accounting for Comprehensive Income" (Statement No. 130), was 
adopted by S&T in 1998. Statement No. 130 establishes new rules 
for the reporting and display of comprehensive income and its 
components. The adoption of this Statement had no impact on S&T's 
net income or shareholders' equity. Statement No. 130 requires 
unrealized gains or losses on S&T's available for sale 
securities, which prior to adoption were reported separately in 
shareholders' equity, to be included in comprehensive income. 
Prior period financial statements have been reclassified to 
conform to the requirements of Statement No. 130. During the 
years ending December 31, 1998, 1997 and 1996, comprehensive 
income amounted to $37,400,000, $48,741,000 and $28,700,000, 
respectively.

Mortgage Loan Servicing

Mortgage servicing assets are recognized as separate assets when 
servicing rights are acquired through purchase or loan 
originations, when there is a definitive plan to sell the 
underlying loan. Capitalized mortgage servicing rights are 
reported in other assets and are amortized into noninterest 
income in proportion to, and over the period of, the estimated 
future net servicing income of the underlying mortgage loans. 
Capitalized mortgage servicing rights are evaluated for 
impairment based on the fair value of those rights. In 1998 and 
1997, $10.9 million and $12.7 million, respectively, of 1-4 
family mortgage loans were sold to the Federal National Mortgage 
Association (FNMA), and $302,000 and $187,000, respectively, of 
mortgage servicing rights were capitalized and recorded in other 
assets.

PAGE 36

Reclassification

Amounts in prior years have been reclassed to conform to 
presentation in 1998. The reclassification had no effect on S&T's 
financial condition or results of operations.

New Accounting Pronouncements

Financial Accounting Standards Board Statement No. 131, 
"Disclosures about Segments of an Enterprise and Related 
Information" (Statement No. 131), is effective in 1998 and 
requires public companies to disclose certain information about 
reportable operating segments in complete sets of financial 
statements of the enterprise. Statement No. 131 does not 
materially affect S&T's financial position or results of 
operations as S&T management views the bank as one segment of 
business which is community banking.

   Financial Accounting Standards Board Statement No. 132, 
"Employers' Disclosures about Pensions and Other Postretirement 
Benefits" (Statement No. 132), is effective in 1998 and 
standardizes the disclosure requirements for pensions and other 
postretirement benefits. Statement No. 132 had no impact on S&T's 
financial position or results of operations.
Financial Accounting Standards Board Statement No. 133, 
"Accounting for Derivative Instruments and Hedging Activities" 
(Statement No. 133), is effective in 1999 and requires measuring 
and recording the change in fair value of hedging activities. S&T 
is currently in the process of evaluating the impact of Statement 
No. 133. Statement No. 133 is not expected to materially affect 
S&T's financial position or results of operations.

Note B
Fair Values of Financial Instruments

S&T utilized quoted market values, where available, to assign 
fair value to its financial instruments. In cases where quoted 
market values were not available, S&T used present value methods 
to estimate the fair value of its financial instruments. These 
estimates of fair value are significantly affected by the 
assumptions made and, accordingly, do not necessarily indicate 
amounts which could be realized in a current market exchange. S&T 
does not expect to realize the estimated amounts disclosed.

   The following methods and assumptions were used by S&T in 
estimating its fair value disclosures for financial instruments:

Cash and Cash Equivalents and 
Other Short-Term Assets

The carrying amounts reported in the consolidated balance sheet 
for cash and due from banks, interest-earning deposits with banks 
and federal funds sold approximate those assets' fair values.

Securities

Fair values for investment securities and securities available 
for sale are based on quoted market prices.

Loans

For variable-rate loans that reprice frequently and with no 
significant change in credit risk, fair values are based on 
carrying values. The fair values for other loans are estimated 
using discounted cash flow analyses, using interest rates 
currently being offered for loans with similar terms to borrowers 
as measured by net credit losses and the loss of interest income 
from nonaccrual loans. The carrying amount of accrued interest 
approximates its fair value.

Deposits

The fair values disclosed for demand deposits (e.g., noninterest 
and interest-bearing demand, money market and savings accounts) 
are, by definition, equal to the amount payable on demand. The 
carrying amounts for variable-rate, fixed-term certificates of 
deposit and other time deposits approximate their fair value at 
year-end. Fair values for fixed-rate certificates of deposit and 
other time deposits are based on the discounted value of 
contractual cash flows, using interest rates currently being 
offered for deposits of similar remaining maturities.

Short-Term Borrowings and
Other Borrowed Funds

The carrying amounts of federal funds purchased, borrowings under 
repurchase agreements and other borrowings approximate their fair 
values.

Long-Term Borrowings

The fair values disclosed for long-term borrowings are estimated 
using current interest rates for long-term borrowings of similar 
remaining maturities.

Loan Commitments and 
Standby Letters of Credit

Estimates of the fair value of these off-balance sheet items were 
not made because of the short term of these arrangements and the 
credit standing of the counterparties. Also, unfunded loan 
commitments relate principally to variable rate commercial loans, 
and fees are not normally assessed on these balances.

PAGE 37

   Estimates of fair value have not been made for items which are 
not defined as financial instruments, including such items as 
S&T's core deposit intangibles and the value of its trust 
operation. S&T believes it is impracticable to estimate a 
representational fair value for these types of assets, which 
represent significant value to S&T.

Derivative Financial Instruments

S&T does not extensively use derivative financial instruments. 
The only type of instrument that S&T utilizes is interest rate 
swaps.

   S&T has one interest rate swap at a notional value totaling 
$10.0 million, paying a fixed-rate and receiving a variable-rate.
The purpose of this transaction was to provide matched, fixed-rate 
funding for newly originated loans, and to mitigate the risk 
associated with volatile liability funding. The effective rate of 
the swap was 5.37% at December 31, 1998. Interest rate swaps are 
not reported in the consolidated balance sheets. Differences 
between interest received and interest paid are reported as a 
component of borrowing expense in the consolidated income 
statement.

Note D
Restrictions on Cash and Due from Bank Accounts

The Board of Governors of the Federal Reserve Bank impose certain 
reserve requirements on all depository institutions. These 
reserves are maintained in the form of vault cash or as a 
noninterest-bearing balance with the Federal Reserve Bank. 
Required reserves averaged $16,988,000 during 1998.

   There were $11,881,000, $6,031,000 and $2,528,000 in gross 
realized gains and $1,159,000, $585,000 and $305,000 in gross 
realized losses in 1998, 1997 and 1996, respectively, relative 
to securities available for sale.

   The amortized cost and estimated market value of debt 
securities at December 31, 1998, by contractual maturity, are 
shown below. Expected maturities will differ from contractual 
maturities because borrowers may have the right to call or 
prepay obligations with or without call or prepayment penalties.

   For purposes of the maturity table, mortgage-backed securities, 
which are not due at a single maturity date, have been allocated 
over maturity groupings based on the weighted-average contractual 
maturities of the underlying collateral. The mortgage-backed 
securities may mature earlier than their weighted-average 
contractual maturities because of principal prepayments.

   The Bank has granted loans to certain officers and directors 
of S&T as well as certain affiliates of the officers and directors 
in the ordinary course of business. These loans were made on 
substantially the same terms, including interest rates and 
collateral, as those prevailing at the time for comparable 
transactions with unrelated persons and did not involve more than 
normal risk of collectibility. The aggregate dollar amounts of 
these loans were $40,862,000 and $41,130,000 at December 31, 1998 
and 1997, respectively. During 1998, $56,514,000 of new loans 
were funded and repayments totaled $56,782,000.

   During 1998, S&T Bank acquired automobile loans and leases on a 
third-party basis from companies owned by two directors of S&T 
totaling $1,982,000. These loans were acquired on substantially 
the same terms as those prevailing at the time for comparable 
transactions with others.

   The principal balances of loans on nonaccrual were $2,933,000 
and $3,602,000 at December 31, 1998 and December 31, 1997, 
respectively. At December 31, 1998, there were no commitments to 
lend additional funds on nonaccrual loans. Other real estate 
owned, which is included in other assets, was $721,000 at 
December 31, 1998 and $647,000 at December 31, 1997.

</TABLE>

   The purpose of these borrowings was to match fund selected 
new loan originations, to mitigate interest rate sensitivity 
risks and to take advantage of discounted borrowing rates 
through the FHLB for community investment projects.

   S&T maintains a Flexline of credit for 10% of total assets 
with the FHLB which expires December 31, 1999. S&T pledged all 
1-4 family and multi-family mortgage loans as collateral for any 
current or future FHLB advances. The total carrying amount of 
these pledged loans was $423,761,000 at December 31, 1998, which 
is the maximum amount to be borrowed under the Flexline. There 
were no Flexline borrowings outstanding at December 31, 1998 and 
1997, respectively.

   During 1998, S&T acquired two repurchase agreement long-term 
borrowings totaling $59,850,000 at a weighted average fixed rate 
of 6.20% which matures in five years.  The purpose of this 
borrowing was to lock in fixed rate fundings to mitigate interest 
rate risk.


Note J
Short-Term Debt

Federal funds purchased and securities sold under repurchase 
agreements (REPOS) generally mature within one to 14 days from 
the transaction date. S&T defines REPOS with its retail customers 
as retail REPOS, and wholesale REPOS are those transacted with 
other financial institutions and brokerage firms.

Note K
Dividend and Loan Restrictions

Certain restrictions exist regarding the ability of S&T Bank to 
transfer funds to S&T in the form of dividends and loans. 
Dividends that may be paid by S&T Bank to S&T are limited to the 
retained earnings of S&T Bank which amounted to $100,142,000 at 
December 31, 1998. The amount of dividends that may be paid to 
S&T is further restricted by regulatory guidelines concerning 
minimum capital requirements.
   
   Federal law prohibits S&T from borrowing from S&T Bank unless 
such loans are collateralized by specific obligations. Further, 
such loans are limited to 10% of S&T Bank's capital and 
additional paid-in capital, as defined. At December 31, 1998, the 
maximum amount available for transfer from S&T Bank to S&T in the 
form of loans and dividends approximated 40% of consolidated net 
assets.

Note L
Litigation

S&T, in the normal course of business, is subject to various 
legal proceedings in which claims for monetary damages are 
asserted. No material losses are anticipated by management as a 
result of these legal proceedings.

S&T, in the normal course of business, commits to extend credit 
and issue standby letters of credit. The obligations are not 
recorded in S&T's financial statements. Loan commitments and 
standby letters of credit are subject to S&T's normal credit 
underwriting policies and procedures and generally require 
collateral based upon management's evaluation of each customer's 
financial condition and ability to satisfy completely the terms 
of the agreement. S&T's exposure to credit loss in the event the 
customer does not satisfy the terms of the agreement equals the 
notional amount of the obligation less the value of any 
collateral. Unfunded loan commitments totaled $372,450,000 and 
$294,144,000 at December 31, 1998 and 1997, respectively; and 
obligations under standby letters of credit totaled $78,490,000 
and $54,439,000 at December 31, 1998 and 1997, respectively.

PAGE 44

   S&T attempts to limit its exposure to concentrations of 
credit risk by diversifying its loan portfolio. S&T defines 
concentrations of credit risk as loans to a specific industry or 
group in excess of 10% of total loans. S&T has no concentration 
of credit risk by industry or group. However, geographic 
concentrations exist because S&T provides a full range of banking 
services including commercial, consumer and mortgage loans to 
individuals and corporate customers in its seven-county market 
area in western Pennsylvania.

Employee Benefits

The Bank maintains a defined benefit pension plan covering 
substantially all employees. The benefits are based on years of 
service and the employee's compensation during the last ten years 
of employment. Contributions are intended to provide for benefits 
attributed to employee service to date and for those benefits 
expected to be earned in the future. Trustee pension plan assets 
consist primarily of equity and fixed income securities and 
short-term investments.

   The following table summarizes the components of net periodic 
pension expense for the Bank's defined benefit plan:

   S&T also has a supplemental retirement plan (SERP) for certain 
key employees. The SERP is unfunded. The balance of actuarial 
present value of projected benefit obligations related to the 
SERP are $2,249,000 and $2,110,000 at December 31, 1998 and 1997, 
respectively. Accrued pension cost related to the SERP was 
$1,971,000 and $1,779,000 at December 31, 1998 and 1997, 
respectively. Net periodic pension cost related to the SERP was 
$244,000, $499,000 and $238,000 at December 31, 1998, 1997 and 
1996, respectively. The actuarial assumptions are the same as 
those used in the previous tables.

   The Bank maintains a Thrift Plan (Plan) in which substantially 
all employees are eligible to participate. The Bank makes 
matching contributions to the Plan up to 3% of participants' 
eligible compensation and may make additional contributions as 
limited by the Plan. Contributions to the Plan are cash or 
unallocated Employee Stock Option Plan (ESOP) shares. Expense 
related to these contributions amounted to $813,000, $990,000 and 
$950,000 in 1998, 1997 and 1996, respectively.

   On December 30, 1988, S&T sold 560,000 shares of common stock, 
which were held in treasury, to its newly created ESOP for 
$2,800,000. The funds were obtained by the ESOP through a loan 
from a bank. S&T has guaranteed the loan, which had a maximum 
term of 10 years and bears interest at 80% of the lender's prime 
rate. The loan terms required quarterly interest and annual 
principal payments. The balance of this loan was zero and 
$130,000 on December 31, 1998 and 1997, respectively, and was 
included in other borrowed funds with an offsetting reduction in 
shareholders' equity shown as deferred compensation in the 
accompanying consolidated balance sheets. At December 31, 1998, 
the ESOP had no unallocated shares remaining.

   The ESOP covers substantially all regular full-time employees. 
S&T is obligated to make annual contributions sufficient to 
enable the ESOP to repay the loan, including interest. Interest 
expense totaled $10,000 in 1998, $17,000 in 1997 and $19,000 in 
1996. Dividends received by the ESOP from S&T for unallocated 
shares amounted to $18,000 in 1998, $24,000 in 1997 and $24,000 
in 1996, which were used for debt service. Dividends on allocated 
shares are paid to the participants' accounts in the Plan. 
Deferred compensation arising from the guarantee of the ESOP 
borrowing was charged to operations as contributions were made to 
the ESOP.

   Since the ESOP was established prior to the issuance of SOP 93-6, 
"Employers' Accounting for Employee Stock Ownership Plans," ESOP 
compensation expense is currently based upon the cost of unearned 
shares as prescribed by SOP 76-3, "Accounting Practices for 
Certain Employee Stock Ownership Plans." The earnings per share 
effects of unearned ESOP shares are not material. The expense 
associated with the release of ESOP shares in 1998, 1997 and 1996 
was $130,000, $100,000 and $110,000, respectively. No allocated 
ESOP shares are subject to repurchase obligations.

Note P
Incentive Stock Plan and Dividend Reinvestment Plan

S&T adopted an Incentive Stock Plan in 1992 (Stock Plan) that 
provides for granting incentive stock options, nonstatutory stock 
options, and stock appreciation rights (SARs). On October 17, 
1994, the Stock Plan was amended to include outside directors. 
The Stock Plan covers a maximum of 3,200,000 shares of S&T common 
stock and expires 10 years from the date of board approval.

   S&T grants stock options equal to the fair market value of S&T 
common stock on the grant date. SARs may be granted concurrently 
with the grant of nonstatutory stock options (Related SARs) or 
independently. SARs entitle the holder to receive either cash or 
shares of S&T common stock equal to the excess of the fair market 
value of the shares subject to the option over the fair market 
value of a share of S&T common stock on the grant date.

   Stock options and SARs granted under the Stock Plan are not 
exercisable before the six-month vesting period from the grant 
date. There were no SARs or Related SARs issued or outstanding at 
December 31, 1998 and 1997.

   Options are granted in December and have a six-month vesting 
period and a 10-year contractual life.

   S&T accounts for stock options in accordance with APB 25. The 
following proforma information regarding net income and earnings 
per share assumes the adoption of Statement No. 123 for stock 
options granted subsequent to December 31, 1994. (Disclosure is 
not required for options granted prior to 1995). The estimated 
fair value of the options is amortized to expense over the option 
and vesting period. The fair value was estimated at the grant 
date using a Black-Scholes option pricing model with the 
following weighted-average assumptions for 1998, 1997 and 1996 
respectively: risk-free interest rates of 4.45%, 5.77% and 6.12%; 
a dividend yield of 2.7%, 3% and 3%; volatility factors of the 
expected market price of S&T's common stock of 0.226, 0.182 and 
0.161; and a weighted-average expected life of five years.

   The Black-Scholes option valuation model was developed for 
use in estimating the fair value of traded options which have 
no vesting restrictions and are fully transferable. In addition, 
option valuation models require the input of highly subjective 
assumptions including the expected stock price volatility. 
Because S&T's employee stock options have characteristics 
significantly different from those of traded options, and 
because changes in the subjective input assumptions can 
materially affect the fair value estimate, in management's 
opinion, the existing models do not necessarily provide a 
reliable single measure of the fair value of its employee stock 
options.

   S&T also sponsors a dividend reinvestment plan (Dividend Plan) 
whereby shareholders may purchase shares of S&T common stock at 
market value with reinvested dividends and voluntary cash 
contributions. American Stock Transfer and Trust Company, the 
plan administrator and transfer agent, purchases the shares on 
the open market to fulfill the Plan's needs.

Note R
Regulatory Matters

S&T is subject to various regulatory capital requirements 
administered by the federal banking agencies. Failure to meet the 
minimum capital requirements can initiate certain mandatory and 
possibly additional discretionary actions by regulators that, if 
undertaken, could have a direct material effect on S&T's 
financial statements. Under capital guidelines and the regulatory 
framework for prompt corrective action, S&T must meet specific 
capital guidelines that involve quantitative measures of S&T's 
assets, liabilities and certain off-balance-sheet items as 
calculated under regulatory accounting practices. S&T's capital 
amounts and classification are also subject to qualitative 
judgements by the regulators about components, risk weightings 
and other factors.

   Quantitative measures established by regulation to ensure 
capital adequacy require S&T to maintain minimum amounts and 
ratios of Tier I and Total capital to risk-weighted assets and 
of Tier I capital to average assets. As of December 31, 1998 
and 1997, S&T meets all capital adequacy requirements to which 
it is subject. 

PAGE 51

   To be classified as well capitalized, S&T must maintain	
minimum Tier I risk-based, Total risk-based and Tier I leverage 
ratios as set forth in the table below:

</TABLE>

   The most recent notification from the Federal 
Deposit Insurance Corporation categorized S&T Bank 
as well capitalized under the regulatory framework for 
corrective action. At December 31, 1998, S&T Bank's 
Tier I and Total capital ratios were 10.42% and 11.68%, 
respectively, and Tier I capital to average assets was 
7.48%. At December 31, 1997, S&T Bank's Tier I and Total 
capital ratios were 13.12% and 14.37%, respectively, and 
Tier I capital to average assets was 9.24%.

Report of Ernst & Young LLP, Independent Auditors
S&T Bancorp, Inc. and Subsidiaries

Shareholders and Board of Directors
S&T Bancorp, Inc.

We have audited the accompanying consolidated balance sheets of 
S&T Bancorp, Inc. and subsidiaries (S&T) as of December 31, 1998 
and 1997, and the related consolidated statements of income, 
changes in shareholders' equity, and cash flows for each of the 
three years in the period ended December 31, 1998. These 
financial statements are the responsibility of S&T's management. 
Our responsibility is to express an opinion on these financial 
statements based on our audits. We did not audit the 1996 
financial statements of Peoples Bank of Unity which statements 
reflect net interest income constituting 18.4% of the related 
consolidated totals. Those statements were audited by other 
auditors whose report thereon has been furnished to us, and our 
opinion, insofar as it relates to data included for Peoples Bank 
of Unity, is based solely on the report of other auditors.

   We conducted our audits in accordance with generally accepted 
auditing standards. 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 
audits provide a reasonable basis for our opinion.

   In our opinion, based on our audits and, for 1996, the report 
of other auditors, the financial statements referred to above 
present fairly, in all material respects, the consolidated 
financial position of S&T Bancorp, Inc. and subsidiaries at 
December 31, 1998 and 1997 and the consolidated results of their 
operations and their cash flows for each of three years in the 
period ended December 31, 1998, in conformity with generally 
accepted accounting principles.

REPORT OF INDEPENDENT AUDITORS

Board of Director and Stockholders
Peoples Bank of Unity

We have audited the accompanying balance sheet of Peoples Bank
of Unity as of December 31, 1996 and 1995, and the related statments
of income, changes in stockholders' equity, and cash flows for each
of the three years in the period ended December 31, 1996.  These
financial statements are the responsibility of the Bank's management.
Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  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 audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Peoples Bank of Unity
as of December 31, 1996 and 1995, and the results of its operations and
its cash flows for each of the three years in the period ended December
31, 1996, in conformity with generally accepted accounting principles.

As explained in the notes to the financial statments, effective January
1, 1995, the Bank changed its method of accounting for the impairment
of loans and related allowance for loan losses, and effective January
1, 1994, changed its method of accounting for investment securities.
