ITEM 8.01    OTHER EVENTS

Chester Valley Bancorp Inc.'s subsidiary First Financial Bank (the "Bank") has
received a subpoena for the production of documents from the Regional Municipal
Securities Counsel in the Philadelphia Office of the Securities and Exchange
Commission (the "SEC"). The subpoena arises out of a non-public SEC
investigation titled "Hummelstown General Authority," which Authority issued
non-rated revenue bonds now in default, underwritten by the firm of a former
director of Chester Valley Bancorp and the Bank.

The SEC subpoena seeks documents concerning non-rated municipal securities,
including those issued to finance the Whitetail Project by the Dauphin County
General Authority and the Hummelstown General Authority, through the former
director's firm, and related matters. First Financial Bank is working with the
SEC lawyers to assist the SEC in its investigation. The Bank previously has
produced documents to the SEC in response to the SEC's voluntary request for
assistance in this matter.
