Form 10-K for the year ended December 31, 1997.

Basic earnings per share 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 earnings per 
share.  Average shares outstanding for computing basic earnings per share were 
14,038,321 and 14,124,341 for the period ending March 31, 1998 and 1997.  
Average shares outstanding for computing dilutive earnings per share were 
14,189,885 and 14,283,194 for the period ending March 31, 1998 and 1997.  In 
computing dilutive earnings per share, average shares outstanding have been 
increased by the common stock equivalents relating to S&T's available 
stock options.

As of January 1, 1998, S&T adopted Statement 130, Reporting Comprehensive
Income.  Statement 130 establishes new rules for the reporting and display 
of comprehensive income and its components; however, the adoption of this
Statement had no impact on S&T's net income or shareholders' equity. 
Statement 130 requires unrealized gains or losses on S&T's available-for-
sale securities, which prior to adoption were reported seperately in share-
holders' equity to be included in comprehensive income.  Prior period financial
statements have been reclassified to conform to the requirements of Statement
130.  During the first quarter of 1998 and 1997, total comprehensive income
amounted to $11,921,000 and $5,508,000.

NOTE D--FINANCIAL INSTRUMENTS
   
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 agreement equals the notional amount of the 
obligation less the value of any collateral.  Unfunded loan committments 
totaled $319,856,000 and obligations under standby letters of credit totaled 
$59,444,000 at March 31, 1998.

At March 31, 1998, S&T had marketable equity securities, totaling $1,786,406 
at amortized cost and $3,652,588 at estimated market value, that were subject 
to covered call option contracts.  The purpose of these contracts was to 
generate fee income for S&T.

NOTE E - 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 BANCORP, INC. AND SUBSIDIARIES
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL 
CONDITION AND RESULTS OF OPERATIONS

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 
Bancorp, Inc. and subsidiaries (S&T).  This discussion
and analysis should be read in conjunction with the 
condensed consolidated financial statements and the 
selected financial data presented elsewhere in this 
report.   All prior period amounts have been restated 
to reflect the pooling of interest transaction with 
Peoples Bank of Unity (Peoples) which closed on May 2, 
1997

Financial Condition

Total assets averaged $1.9 billion in the first three 
months of 1998, a $132.5 million increase from the 
1997 full year average.  Average loans increased $47.2 
million and average securities and federal funds 
increased $64.1 million in the first three months of 
1998 compared to the 1997 full year averages.  Funding 
for this loan and security growth was primarily 
provided by a $23.3 million increase in average 
deposits, a $16.1 million increase in average retained 
earnings and  a $86.8 million increase in average 
borrowings.

Lending Activity

Total loans at March 31, 1998 were $1.3 billion, a 
$17.1 million or 1.3% increase from December 31, 1997.  
Average loans increased $47.2 million, or 4% to $1.3 
billion for the three months ended March 31, 1998 from 
the 1997 full year average.  Changes in the 
composition of the loan portfolio during 1998 included
increases of $14.7 million of  commercial loans, $18.3
million of commercial real estate loans, offset by a 
decrease of $8.9 million of residential mortgages and 
and $7.0 million of installment loans.

Commercial real estate loans comprise 26% of the loan 
portfolio.  Although real estate loans can be an area 
of higher risk, management believes these risks are 
mitigated by limiting the percentage amount of 
portfolio composition, a rigorous underwriting review 
by loan administration and the fact that many of the 
commercial real estate loans are owner-occupied and/or 
seasoned properties that were refinanced
from other banks.

Residential mortgage lending continued to be a 
strategic area of focus during the first three months 
of 1998 through a centralized mortgage origination 
department, ongoing product redesign, the 
utilization of commission compensated originators  
and the implementation of a mortgage banking function.
Management believes that if a downturn in the local 
residential real estate market occurs, the impact of 
declining values on the real estate loan portfolio 
will be negligible because of S&T's conservative 
mortgage lending policies.  These policies generally 
require, for portfolio loans, maximum term of twenty 
years for fixed rate mortgages and private mortgage 
insurance for loans with less than a 20% down payment.  
At March 31, 1998 the residential mortgage portfolio 
had a 26% composition of adjustable rate mortgages.

Beginning in the fourth quarter of 1997, S&T sold $12.7 million
of long-term, lower-yielding 1-4 family mortgages, 
acquired from the Peoples merger, to the Federal National 
Mortgage Association (FNMA).  S&T retained ongoing servicing 
rights on the mortgages 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.  S&T will continue 
to sell 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.   Pricing pressures have been unusually 
intense in the indirect market during the last two 
years and the decision was made to temporarily deploy 
investable funds into other higher yielding and lower 
risk earning assets.  In the second quarter of 1996, 
S&T implemented an indirect auto leasing program and 
currently has $4.3 million of outstanding auto leases.  
Installment loans have also decreased due to  recent 
changes in government regulations which have 
significantly decreased the profit potential of

guaranteed student loans.  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.

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 loans is generally 75%.

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 do not exceed
100% of 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 are 90%-125% of 
invoice for new automobiles and 100%-125% of "Black 
Book" value for used automobiles.

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 $69.0 million in the 
first three months of 1998 compared to the 1997 full 
year average.  The increase in the average investment 
portfolio was related to an increase in average 
taxable securities of $76.0 million, offset by a 
decrease in tax-exempt state and municipal securities 
average balances of $7.0 million.   This increase was 
comprised of $78.9 million in U.S. government agency 
securities, $2.2 million of mortgage-backed 
securities, $0.5 million of corporate securities and 
$3.8 million of Federal Home Loan Bank (FHLB) stock.  
Offsetting these increases were average decreases of 
$9.4 million of U.S. treasury securities. 

During 1998 S&T purchased $105.2 million of intermediate-
term U.S. government agency  securities classified as 
available for sale.  These purchases were made as part 
of a balance sheet leveraging strategy to maximize net 
interest income by taking advantage of low, short-
term funding rates.  Proceeds from the sale of available
for sale securities were $5.2 million, including 
equity securities sales of $3.2 million which were 
made in order to maximize returns when market  
opportunities are presented.

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 11.0% on a fully taxable 
equivalent basis and had unrealized gains net of 
nominal unrealized losses, of  $62.2 million.  The 
equity securities portfolio consists of securities 
traded on the various stock markets and are subject to 
change in market value.  The FHLB capital stock is a 
membership and borrowing requirement and is acquired 
and sold at stated value.
11

S&T BANCORP , INC. AND SUBSIDIARIES
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL 
CONDITION AND RESULTS OF OPERATIONS

S&T's policy for security classification included U.S. 
treasuries, U.S. government agencies, mortgage-backed 
securities, CMOs and corporate equities as available 
for sale.  Municipal securities and other debt 
securities are classified as held to maturity.  At 
March 31, 1998, unrealized gains, net of unrealized 
losses for securities classified as available for sale 
were $66.5 million.

Allowance for Loan Losses

The allowance for loan losses increased to $21.7 
million or 1.68% of total loans at March 31, 1998, as 
compared to $20.4 million or 1.60% of total loans at 
December 31, 1997.  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, growth and composition of 
the loan portfolio as well as other relevant factors.  

The balance of nonperforming loans at March 31, 1998, 
which includes nonaccrual loans past due 90 days or 
more, was $3.2 million, or 0.25% 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 $23.3 million, or 
2% for the three months ended March 31, 1998 as 
compared to the 1997 average. Changes in the average 
deposit mix included a $9.6 million increase in time 
deposits, $22.2 million increase in money market 
accounts and a $5.6 million increase in demand 
accounts, offset by a $12.4 million decrease in 
savings accounts and a $1.7 million decrease in NOW 
accounts.

Special rate deposits of $100 thousand and over were 
7% of total deposits at March 31, 1998 and December 
31, 1997 and primarily represent deposit relationships 
with local customers in our market area.  Retail time 
deposit increases of $9.6 million were the result of 
expanded promotional programs.  

During the second half of 1995, S&T issued $25.0 
million of retail certificates of deposits through two
brokerage firms, further broadening the availability 
of reasonably priced deposit funds.  At  March 31, 
1998, there were $26.6 million of these brokered 
retail certificates of deposits outstanding.  Money 
market accounts were recently repriced in order to be
more competitive with money funds offered by brokerage
firms.  As a result of this repricing and proactive 
sales activities to high-balance deposit customers,  
S&T has experienced a significant shift in funds from 
savings to money market accounts.  Although this 
strategy tends to increase cost of funds, management 
believes it is necessary for customer retention and 
the development of long-term relationships.

The decrease in NOW balances is attributable to the 
implementation of a NOW/money market sweep product on 
the accounts acquired from Peoples that reduces the 
amount of Federal Reserve Requirements.
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.  In addition, S&T has the ability to 
access both public and private markets to raise 
long-term funding if necessary.

CONDITION AND RESULTS OF OPERATIONS

Borrowings

Average borrowings increased $86.8 million for the 
three months ended March 31, 1998 compared to the 1997 
annual average and were comprised of retail repurchase 
agreements (REPO's), wholesale REPO's, federal funds 
purchased and long-term borrowings.  S&T defines 
repurchase agreements with its local, retail customers 
as retail REPOS; wholesale REPOS are those transacted 
with other banks and brokerage firms with terms 
normally ranging from 1 to 14 days.

The average balance in retail REPOS  increased 
approximately $7.1 million for the first three months 
of 1998 compared to the full year 1997 average.    
This  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.  

Wholesale REPOS and federal funds increased $40.4 
million for the first three months of 1998 compared to 
the full year 1997 average.  The aforementioned 
balance sheet leveraging strategy has increased  the 
usage of wholesale REPO fundings in 1998.

Average long-term borrowings have increased $39.3 
million in the first three months of 1998 as compared 
to the full year 1997 average.  At March 31, 1998, S&T 
had long-term borrowings outstanding of $49.6 million 
at a fixed rate and $94.6 million at an adjustable 
rate with the FHLB.  The purpose of these borrowings 
was to provide matched, fixed rate fundings for newly 
originated loans, to mitigate the risk  associated 
with volatile liability fundings and to take advantage 
of lower cost funds through the FHLB's Community 
Investment Program.  

Capital Resources

Shareholders' equity decreased $8.8 million at March 
31, 1998, compared to December 31, 1997.  Net income 
was $9.2 million and dividends paid to shareholders 
were $4.2 million for the three months ended March 31,
1998.  The decrease is attributable to the conclusion 
of the Modified Dutch Auction in which S&T repurchased 
approximately 440,000 shares of its common stock.  
During the first three months of  1998, S&T paid 46% 
of net income in dividends, equating to an annual 
dividend rate of $1.20 per share.  

The book value of S&T's common stock decreased 
slightly from $18.39 at December 31, 1997 to $18.12 at
March 31,1998, primarily due to the stock buy-backs
during the first quarter of 1998.  Equity associated 
with the available for sale securities portfolio 
increased $2.3 million during the first three months 
of 1998 due to stabilized interest rates and the 
resulting increase in values of debt and equity 
securities.  The market price of S&T's common stock 
was $55.38 per share at March 31, 1998, an increase 
from $43.25 per share at December 31, 1997. 

S&T continues to maintain a strong capital position 
with a leverage ratio of 10.7% as compared to the 
minimum regulatory guideline of 3.0%. S&T's risk-based 
capital Tier I and Total ratios were 15.8% and 17.0% 
respectively, at March 31, 1998.  These ratios place 
S&T well above the Federal Reserve Board's risk-based 
capital guidelines of 4.0% and 8.0% for Tier I and 
Total, respectively.

RESULTS OF OPERATIONS

Three months ended March 31, 1998 compared to
Three months ended March 31, 1997

Net Income

Net income increased to $9.2 million or $0.65 per 
diluted earnings per share in the first three months 
of 1998 from $7.7 million or $0.54 per diluted 
earnings per share for  the same period of 1997.  The 
significant improvement during the three months of 
1998 was the result of higher net interest income, 
increased noninterest income, higher security gains 
and reduced operating expenses due to the Peoples 
merger related costs incurred in the first 
quarter of 1997 and post merger restructurings.

Net Interest Income

On a fully taxable equivalent basis, net interest 
income increased $0.9 million or 5% in the first three 
months of 1998 compared to the same period of 1997.  
The net  yield on interest-earning assets was 4.70% in 
the first three months of 1998 as compared to 4.91% in 
the same period of 1997.  

Net interest income was affected by a change in the 
mix of funds as S&T implemented the aforementioned 
balance sheet leveraging strategy.  This balance sheet
leveraging strategy, combined with the first quarter
stock buy-backs from the Modified Dutch Tender Offer,
contributed to the 21 basis point decline in the net
yield on interest-earning assets.  Net interest income,
was positively affected by the strategy and the growth
in loan and deposit volumes.  The level and mix 
of funds is continually monitored by ALCO in order to 
mitigate the interest rate sensitivity and liquidity 
risks of the balance sheet.

In the three months of 1998, average securities 
increased $70.0, comprising most of the earning asset 
growth, and average loans increased $47.2 million.   
The yields on average securities increased by 32 basis 
points during the period and the yield on average 
loans increased by 5 basis points.   The yield 
increase for securities is a result of the 
aforementioned balance sheet leveraging strategy.

Average interest bearing deposits provided $17.6 
million of the funds for the growth in securities and 
loans; cost of deposits totaled 4.38%, an increase of 
5 basis points from 1997.  The cost of REPOS and other 
borrowed funds decreased 4 basis points to 5.49%.  
More longer-term borrowings were utilized in 1998 in 
order to take advantage of low, long-term funds rates
and to mitigate interest rate risk.

Also positively affecting net interest income was a 
$6.8 million increase to average net free funds.  
Average net free funds are the excess of  demand 
deposits, other non-interest bearing liabilities and
shareholders' equity over non-earning assets.

Maintaining consistent spreads between earning assets 
and costing liabilities is very significant to S&T's 
financial performance since net interest income 
comprises 87% of operating revenue.  A variety of 
asset/liablity 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 increased to $2.1 
million for the first three months of 1998 as compared 
to $1.6 million in the same period of 1997.  The 
increase was the result of management's assessment of 
economic conditions, credit quality statistics, loan 
administration effectiveness and other factors that 
would have an impact on future probable losses in the 
loan portfolio.  
14

S&T BANCORP, INC. AND SUBSIDIARIES
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL 
CONDITION AND RESULTS OF OPERATIONS

Credit quality statistics are an important factor in 
determining the amount of provision expense.  Net loan 
charge-offs totaled $0.7 million for the first three 
months of 1998 compared to $0.3 million for the same 
period 1997.  Nonperforming loans to total loans was 
0.25% at March 31, 1998 and 0.62% in the same period 
of 1997.

Also affecting the amount of provision expense is loan 
growth.  Despite a $47.2 or 4% increase in average 
loans,  S&T's allowance for loan losses to total loans 
remained relatively constant at 1.68% at March 31, 
1998 compared to 1.64% at March 31, 1997.

Noninterest Income

Noninterest income increased $1.4 million or 35% in 
the first three months of 1998 compared to the same 
period of 1997.  Increases included $0.2 million or 
20% in service charges and fees, $0.2 million in trust 
income, $0.8 million in security gains and $0.2 
million in other income.

The increase in service charges on deposit accounts 
was primarily the result of  expanding new cash 
management relationships and 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 service charges in the fourth quarter of 1997.  
The increase in trust fees is attributable to expanded 
marketing efforts to develop new trust business and to 
develop new relationships within the Allegheny County 
market.  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  strategic 
initiatives and product enhancements implemented in 
order to expand this source of revenue.

Security gains were taken on available for sale 
equities securities in the first three months of 1998 
in order to maximize returns by taking advantage of 
market opportunities when presented.  Unrealized 
gains, net of unrealized losses, in the available for 
sale equities portfolio totaled $62.2 million at March 
31, 1998.

Noninterest Expense

Noninterest expense decreased $0.4 million or 3% at 
March 31, 1998 compared to March 31, 1997.  The 
decrease is primarily attributable to $0.4 million of 
merger  related and other nonrecurring expenses 
associated with the acquisition of Peoples during the 
first quarter of 1997, and reduction in 
full-time-equivalent staff levels.  Merger related and 
other nonrecurring expenses included legal, accounting 
and investment banker expenses.    

Recurring expenses were relatively flat during the 
first quarter of 1998 as compared to the first quarter 
of 1997.  Average full-time equivalent staff decreased 
from 673 to 652.  Severance and early retirement 
programs were implemented in May 1997 in order to 
eliminate duplicate positions following post merger 
restructuring and consolidation of operations.  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, 
improved to 43.64% at March 31, 1998 as compared to 
46.63% at March 31, 1997.
   
Federal Income Taxes

Federal income tax expense increased $0.8 million at
March  31, 1998 as compared to March 31, 1997 
primarily as a result of higher pre-tax income in 
1998.  The effective tax rate for the first three 
months of 1998 was 30% and 29% during the same period of 
1997, which is below the 35% statutory rate due to
benefits resulting from tax-exempt interest, 
excludable dividend income and low income housing 
tax credits (LIHTC).

CONDITION AND RESULTS OF OPERATIONS

Year 2000

In June 1997, S&T management formed a committee 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.  Management and the committee 
expect to have substantially all of the system and 
application changes completed and tested by the end of 
1998 and believe that its level of preparedness is 
appropriate.

S&T has estimated the total cost of the project to be 
$250,000 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.
