                           CHESTER VALLEY BANCORP INC.
                         REPORTS SECOND QUARTER EARNINGS

FOR IMMEDIATE RELEASE

WEDNESDAY JANUARY 26, 2005

CONTACT: JOSEPH T. CROWLEY
         TREASURER & CHIEF FINANCIAL OFFICER
         (610) 269-9700 EXT. 3085

Downingtown - Chester Valley Bancorp Inc. announces that the Company posted
earnings of $1.605 million for its second quarter ended December 31, 2004. This
represents the second highest quarterly earnings in the history of the Company.
This compared to earnings of $1.598 million for the quarter ended December 31,
2003. On a diluted share basis, the Company earned $0.30 per diluted share for
each of the quarters ended December 31, 2004 and December 31, 2003. Earnings for
the six months ended December 31, 2004 were $3.127 million as compared to $3.112
million for the six months ended December 31, 2003. Diluted earnings per share
were $0.59 for both periods.

While earnings were relatively stable from period to period, the Company
reported net interest income of $5.203 million and $10.317 million for the three
and six months ended December 31, 2004, respectively. This compares to $4.743
million and $9.451 million for the comparable periods ended December 31, 2003,
respectively. This represents a 9.7% increase for the quarter and a 9.2%
increase for the year to date results. After years of pressure and a resulting
decline in the Company's net interest margin, the Federal Reserve Bank's recent
rate hikes along with the growth experienced within the loan portfolio, have
positively impacted the Company's net interest margin. The net interest margin
and net interest spread (computed on a fully tax equivalent basis) increased to
3.50% and 3.45%, respectively, during the quarter from 3.47% and 3.42%,
respectively, for the quarter ended September 30, 2004. This represents the
third sequential quarter in which the Company has experienced an increase in
both its net interest margin and net interest spread. Future increases in
short-term interest rates should have a positive impact on the Company's
earnings, as the Company continues to be asset sensitive.

Non-interest income decreased to $2.353 million for the quarter ended December
31, 2004, an 8.4% decrease from the quarter ended December 31, 2003. Excluding
gains on the sale of securities, non-interest income increased by $161 thousand
or 8.0% over the same quarterly comparisons. The increases occurred primarily in
investment services income, including trust fees along with increases in deposit
fees resultant from a growth in transaction type deposit accounts (i.e. Consumer
and business checking, money market and savings) as well as income realized upon
the sale of single-family residential mortgage loans available for sale. For the
six months ended December 31, 2004, non-interest income decreased to $4.442
million, or 3.1% as compared to the six months ended December 31, 2003.
Excluding gains on the sale of securities, non-interest income increased by $234
thousand or 5.9% over the same six month comparisons. The increases occurred
primarily in the same categories noted above in the quarterly comparison.



The above noted increases were offset in part by an increase in operating
expenses, primarily in compensation and benefits, which was partially offset by
a reduction in legal expenses (included in other expenses on the Consolidated
Statement of Operations). In addition to normal salary increases for the year,
the Company has made a significant investment in its future. The Company
expanded its retail brokerage business personnel in September 2004.
Additionally, on a yearly comparison, the Bank hired six lending and
private-banking relationship managers who became available as a result of the
recent consolidation within the local community banking market. In addition the
Bank expanded its branch network through the Coatesville and Avondale branch
acquisitions from PNC National Bank in March 2004 and December 2004,
respectively. Additionally, in August 2004, the Bank opened a loan production
office in Plymouth Meeting, Montgomery County, Pennsylvania, an area that was
largely impacted by the afore-mentioned consolidation; and a Private Client
office in West Chester Borough in June 2004 to better serve the complex needs of
affluent clients and the professionals who handle their business affairs. As
with other institutions, the Company has incurred increased costs related to the
implementation of the final rules of Section 404 of the Sarbanes-Oxley Act of
2002. For the three and six months ended December 31, 2004, these costs were
$65,000 and $108,000, respectively.

At December 31, 2004, total assets increased to $669.1 million as compared to
total assets of $642.1 million at June 30, 2004, or 4.2%. At December 31, 2004,
loans receivable, net increased by $28.5 million or 7.2% to $423.6 million as
compared to $395.1 million at June 30, 2004. For the quarter ended December 31,
2004, the loan portfolio increased $23.5 million or 5.9% as compared to loans
receivable, net at September 30, 2004. The growth continues to be concentrated
in construction and commercial loans. In December 2004, the Company completed
the acquisition of the Avondale branch from PNC National Bank, which resulted in
increased consumer loans of $5.9 million and the assumption of approximately
$8.9 million in deposit liabilities.

The loan growth was funded through a reduction in interest-bearing deposits as
well as deposits assumed in the Avondale branch acquisitions along with Federal
Home Loan Bank advance borrowings. As in the prior quarter, the Company
continues to have a large amount in undisbursed closed construction and
commercial loans available for future funding. These aggregate $68.8 million at
December 31, 2004, an increase of $16.3 million as compared to September 30,
2004. Additionally, at December 31, 2004, the pipeline remains strong at
approximately $25.3 million, mostly in commercial and construction loans. The
loans are at various stages of the commitment and customer acceptance process.
The ultimate closing of these loans is dependent upon a number of factors
including but not limited to; (a) competition within the marketplace, (b)
changes in interest rates during the process and (c) other factors impacting the
customer. At December 31, 2004, the Company's non-performing assets to total
assets declined to 0.54% from 0.64% at September 30, 2004. Additionally, the
allowance for loan losses to non-performing loans increased to 190.5% at
December 31, 2004 from 147.3% at September 30, 2004. The improved credit quality
measurements were attributed primarily to the Company's receipt of a $750
thousand principal pay-down on an approximate $2.9 million non-performing
commercial mortgage. Additionally, the borrower prepaid interest as a condition
to the Bank's extension of the maturity date on the remaining balance of the
loan.

Donna Coughey, President and CEO stated, "While loan demand has increased, the
competition within our market is intense for both loans and deposits. Despite
this competition, our loan closings were strong, particularly at the end of
December. These closings, the future funding of lines of credit closed during
the year, and the continued asset sensitivity of the Company's balance sheet
should positively impact future earnings. The anticipated continued rising
interest rate environment could, however, pose a challenge in maintaining the
type of deposit growth experienced in the more recent years. However, the
successful acquisition of the Avondale and Coatesville branches from PNC
National Bank and the opening of a de novo branch in Oxford provide us with
growth opportunities not available in those recent years. We will continue to
seek opportunities to enhance our existing branch networks through both external
acquisitions as well as internal growth. Our recently opened Plymouth Meeting
loan production office continues to provide us with a stronger presence in a
market that has been impacted by the recent consolidation within the local
community banking industry."



Joseph Crowley, Chief Financial Officer added, "The growth and re-structuring of
the loan portfolio has continued to enhance our core banking operations. Pre-tax
core banking income (income excluding gains on securities available for sale)
increased to $2.037 million for the three months ended December 31, 2004 from
$1.546 million for the three months ended December 31, 2003 or 31.8%. Our net
interest margin continues to increase as a result of the loan growth as well as
the recent increase in market interest rates. Our balance sheet continues to be
structured in such a manner as to benefit from any future increase in short-term
rates by the Federal Reserve."

On January 20, 2005, the Company issued a press release announcing its intent to
