Item 5. Other Events

         On July 22, 2002, First Niagara Financial Group, Inc. (the
"Registrant") issued a press release reporting that the Board of Directors of
First Niagara Financial Group, MHC (the "MHC") has adopted a Plan of Conversion
to convert the MHC to a capital stock corporation (the "Conversion"). The MHC
owns approximately 62% of the outstanding common stock of the Registrant. Upon
consummation of the Conversion, the MHC will cease to exist and its shares of
the Registrant's stock will be cancelled. Existing shares of the Registrant's
common stock held by public stockholders will be exchanged for new shares of the
Registrant, pursuant to an exchange ratio that has yet to be determined and will
be based on an independent appraisal.

         Additionally, the Registrant announced that it entered into a
definitive merger agreement with Finger Lakes Bancorp, Inc., pursuant to which
the Registrant will acquire all of the outstanding shares of Finger Lakes
Bancorp, Inc. (the "Acquisition"). Finger Lakes Bancorp, Inc. is the holding
company of Savings Bank of the Finger Lakes. The merger consideration will be
50% Conversion Stock and 50% cash. It is expected that the aggregate purchase
price of the transaction will be approximately $67 million.

         A conference call concerning the Conversion and Acquisition
announcement will be held at 2:00 p.m. Eastern Standard Time on Monday, July 22,
2002. Interested shareholders, investors and analysts should call (888) 694-4767
