Downingtown - Chester Valley Bancorp Inc. announces that the Company posted
quarterly and year to date earnings of $1.48 million, or $0.31 per share
(diluted) and $4.37 million or $0.93 per share (diluted) for the three- and
nine-month periods ended March 31, 2003. This compared to $1.48 million or $0.32
per share (diluted) and $4.42 million or $0.97 per share (diluted) for the same
three- and nine-month periods in 2002.

Commercial loans increased $22.43 million or 13.5% to $188.83 million for the
nine-month period. Loan quality for the Company remained stable as
non-performing loans represented only .16% of total assets at March 31, 2003.
The decrease in the provision for loan losses of $217 thousand and $253 thousand
for the three- and nine-month periods ended March 31, 2003 when compared to the
same periods in 2002 is reflective of the $20.64 million or 5.5% in runoff of
residential mortgage loans and improved loan quality.

For the nine-month period ended March 31, 2003, we increased core deposits by
$48.08 million or 25.0% while simultaneously decreasing our higher-cost
certificates of deposit by $17.20 million. In addition, we reduced costly
municipal certificates of deposit by $2.61 million. Total assets for Chester
Valley increased 4.0% for the past nine months to $588.40 million at March 31,
2003, from $566.03 million at June 30, 2002.

Non-interest income increased 17.4% to $5.7 million for the nine-months ended
March 31, 2003 over the same nine-month period ending March 31, 2002. The 50
basis point drop in interest rates resulted in a decrease in net interest income
for the nine-month period. Our interest rate spread declined 6 basis points to
3.35% from 3.41% for the nine-month period.

"Our focus has, and will continue to be, increasing core deposits, growing the
commercial loan portfolio and expanding fee income. Commercial loans and core
deposits continue to show strong, healthy growth. Our nine-month fee income from
investment services, loan fees and deposit service charges increased 14.5% to
$4.8 million from $4.2 million at March 2003 and March 2002, respectively. The
current interest rate environment and the slow economy continue to pose
challenges for the financial services industry," stated Donna M. Coughey,
President & CEO.
