FIRST NIAGARA FINANCIAL GROUP, INC. TO CONDUCT SECOND STEP
           CONVERSION OFFERING AND ACQUIRE FINGER LAKES BANCORP, INC.

Lockport, New York- (July 22, 2002) The Board of Directors of First Niagara
Financial Group, Inc. (the "Company") (Nasdaq: FNFG) announced that the Board of
Directors of First Niagara Financial Group, MHC (the "MHC") has adopted a Plan
of Conversion (the "Plan") to convert the MHC to a capital stock corporation
(the "Conversion"). The MHC, headquartered in Lockport, New York, owns
approximately 62% of the outstanding common stock of the Company. Public
stockholders own the remaining shares. The Company owns 100% of the outstanding
capital stock of First Niagara Bank, Cayuga Bank and Cortland Savings Bank.

Pursuant to the Plan, the Company will conduct a subscription offering of common
stock to eligible current and past depositors. Shares not subscribed for in the
subscription offering are expected to be available for sale in a community
offering to the general public. The number and price of shares to be issued in
the Conversion offering (the "Offering") will be based on an independent
appraisal that has yet to be performed.

The Company also announced that a definitive merger agreement (the "Agreement")
has jointly been signed by First Niagara Financial Group, Inc. and Finger Lakes
Bancorp, Inc., pursuant to which the Company will acquire all of the outstanding
shares of Finger Lakes Bancorp, Inc. (Nasdaq:FLBC) (the "Acquisition"). Finger
Lakes Bancorp, Inc. is the holding company of Savings Bank of the Finger Lakes.

The Conversion, Offering and Acquisition are expected to be completed in the
first quarter of 2003 and will be consummated simultaneously. Upon consummation
of the Conversion, the MHC will cease to exist and its shares of Company stock
will be cancelled. Existing shares of the Company's common stock held by its
public stockholders will be exchanged for new shares of the Company, pursuant to
an exchange ratio based on the minority ownership percentage of the independent
appraisal described above.

The Company will pay $20 per share for each outstanding share of Finger Lakes
Bancorp. The purchase price represents 171% of Finger Lakes book value as of
June 30, 2002, 21.7 times second quarter 2002 annualized earnings and 11.4 times
second quarter 2002 annualized earnings including anticipated after tax expense
savings. 50% of the consideration will be in First Niagara Conversion Stock, and
50% will be in cash. It is expected that the aggregate purchase price of the
transaction will be approximately $67 million.

"We have successfully put to work the capital raised in our 1998 initial public
offering and we are now poised for further strategic growth," William E. Swan,
Chairman, President & CEO of First Niagara Financial Group, Inc. and First
Niagara Bank said. "We have chosen to undergo a stock conversion and to make
what we believe is a very favorable acquisition which will connect our western
and central New York markets. The additional capital we raise in the stock
offering will help support future growth internally and through acquisitions."

into First Niagara Bank. Chairman, President and CEO of Finger Lakes Bancorp,
Inc., G. Thomas Bowers, will join First Niagara Financial Group, Inc.'s Board of
Directors and provide continued leadership. Commenting on the agreement, Bowers

Directors believes this agreement is in the best interests of our shareholders.
This is an opportunity to join forces with an outstanding banking company that,
like Finger Lakes, has long provided superior community banking products while
valuing their employees and community."

Cost efficiencies have been identified within this acquisition and some
management, support and administrative positions held by Finger Lakes Bancorp,
Inc. staff will be eliminated. Those displaced will be offered severance,
opportunities to post for positions within First Niagara Financial Group and its
subsidiaries for which they are qualified, and outplacement assistance.

The Merger, exclusive of the "second step" offering, is anticipated to be
accretive to First Niagara Financial Group's estimated earnings per share by

approximately $4.25 million pre-tax. Finger Lakes gives First Niagara market
share in 3 adjacent counties that it does not currently operate in, Ontario,
13.29%; Seneca, 7.43%; and Tompkins, 5.01%. The transaction also gives First
Niagara the number 3 market share rank in Ontario County, and further

stockholders. The Conversion with the Acquisition are subject to the approval of
