                  ESBF ANNOUNCES SIX FOR FIVE STOCK SPLIT
                  ---------------------------------------

Ellwood City, Pennsylvania.  ESB Financial Corporation (Nasdaq NMS:
ESBF) announced today that the Board of Directors has declared a six for
five stock split of ESBF common stock, which is payable on May 15, 2003
to the stockholders of record at the close of business on May 1, 2003.
As of April 15, 2003, there were 8,788,383 shares of common stock
outstanding and 2,336 registered stockholders of record. The number of
stockholders of record does not include the number of persons or
entities who hold their stock in nominee or "street" name.

Charlotte A. Zuschlag, President and Chief Executive Officer, noted that
the Company's strong results from operations for the year ended 2002,
and for the first three months ended March 31, 2003, was a reason behind
the announcement. The Company reported net income of $8.96 million or
$1.03 per diluted share for year ended December 31, 2002, and net income
of $2.4 million or $0.27 per diluted share for the three months ended
March 31, 2003.

Ms. Zuschlag stated, "This six for five stock split represents the ninth
such stock split since the Company went public in June 1990. The Board
of Directors declared this stock split in order to reflect the
appreciation of the stock price since 1990 and to increase the number of
outstanding shares. This should amplify trading activity, or float, in
our common stock." Ms. Zuschlag also stated, "The Board is most pleased
to announce this stock split. This stock split, combined with our
maintaining the current payout of $0.10 per share quarterly cash
dividend, effectively increases the cash payout to our stockholders by
20%."
