Duggan to Retire at Year-End



Indiana, Pennsylvania (Nasdaq NMS:STBA) - The Board of

Directors of S&T Bancorp announced at its September Board 

meeting that it has accepted Robert D. Duggan's retirement 

plans.  Duggan intends to retire as chief executive officer of 

the Corporation and S&T Bank, effective December 31, 1997.  

Duggan has been the chief executive officer of S&T Bancorp 

and S&T Bank since 1982.  He will remain the chairman of 

both Boards of Directors.  Duggan will be 65 in February, 

1998.



The Board of Directors stated, "Bob has done a tremendous 

job in leading this organization for 17 years.  When he joined 

S&T in 1980, after 21 years with the Federal Reserve, it was 

a $200 million bank with offices located in Indiana, Saltsburg 

and Punxsutawney.  Today, S&T has over $1.8 billion in 

assets with 38 offices in six Western Pennsylvania counties.  

More importantly, S&T has a strong customer service culture 

and has generated financial performance second to none.  It is 

consistently recognized as one of the best bank holding 

companies for its size in the country, thanks in large part to 

Bob's leadership."



James C. Miller, president and chief operating officer of S&T 

Bancorp and S&T Bank, will become chief executive officer of 

both organizations, effective January 2, 1998.  Mr. Miller has 

been the chief operating officer of the holding company and 

the bank since 1993.  Mr. Miller joined S&T Bank in 1983, 

when S&T acquired Unibank in Brookville, PA where he was 

an Executive Vice President.



Miller added, "While Bob will be retiring as the chief executive 

officer, he will continue to play a very important role for S&T 

going forward.  In addition to his ongoing responsibilities as 

chairman, I am very pleased that Bob will continue to actively 

support S&T's merger and acquisition strategy and be available 

to provide advice and counsel to our senior management 

staff.
