                            COMBINED MANAGEMENT TEAM

MAPLE GLEN, PA AND DOWNINGTOWN, PA--FEBRUARY 1, 2005--Today Willow Grove
Bancorp and Chester Valley Bancorp announced the management team that will lead
the combined bank upon closing of their recently announced merger. The combined
bank's management team will draw from the best of both banks.

     As announced previously, Chester Valley President and CEO Donna Coughey
will be named President and CEO of the combined bank. Willow Grove President and
CEO Fred Marcell will continue to serve on the Boards of Directors of the bank
and the holding company.

     Joining Donna Coughey from the Chester Valley organization will be Joseph
T. Crowley, Chief Financial Officer; Matthew D. Kelly, Chief Wealth Management
Officer; and G. Richard Bertolet, Chief Lending and Sales Officer. From the
Willow Grove side, senior executives will include Christopher E. Bell, Chief
Operating Officer; Jerome P. Arrison, Treasurer; and Ammon J. Baus, Chief Credit
Officer.

     Donna Coughey said, "I'm pleased at the prospect of joining with this group
of talented and experienced individuals. Our team brings nearly 200 years of
combined banking and financial services industry experience to the table from
both large and small banks, commercial banks and thrifts. I'd gladly stack this
group up against any bank leadership team in the region."

     Fred Marcell added, "The game plan for the combined bank is to attack a
great market opportunity for a locally-based, locally-focused community bank
with enhanced resources. The team that we have assembled to lead this
organization clearly has the talent to seize the day and drive our growth
strategy, which we expect to result in greater shareholder value."



     The bank will also introduce two Regional Presidents: John Powers will
serve as Regional President of the Willow Grove Bank region, and Colin Maropis

Colin will lead the local banks and will report to Dick Bertolet, Chief Lending
and Sales Officer.

will allow us to maintain our strong local roots. John and Colin are
longstanding bank employees and well-respected members of their local
communities who have their fingers on the pulse of the local communities."
