                       Second Step Conversion and Timing
- --------------------------------------------------------------------------------



[LOGO]

Conversion Overview
- --------------------------------------------------------------------------------

>> We will undergo a second step conversion, converting from MHC structure to a
   fully public company.

>> First Niagara Financial Group will sell to the public the 62% ownership stake
   held by First Niagara Financial Group, MHC.

>> Shares will be offered to the depositors via a subscription offering.

>> Any remaining shares from subscription offering will be sold through a
   community offering, syndicated community offering and/or underwriting.

>> Concurrently with the closing of the offering, First Niagara's current
   shareholders will receive shares in the New Holding Company in exchange for
   the shares they currently own.


[LOGO]

Timing
- --------------------------------------------------------------------------------

>> We are proceeding with a second step conversion at this time to take
   advantage of the strong conversion market. We believe that this will maximize
   shareholder value.

>> Recent conversion activity in general and Second Step conversions
   specifically have been well received by depositors, and the aftermarket
   performance of recently converted companies has been strong.

>> The recent Second Step conversion in Massachusetts was oversubscribed, and
   had an initial stock price increase of 14% after the first week of trading.

Strategic Rationale
- --------------------------------------------------------------------------------

>> Fill in acquisition for our franchise.

>> Immediately accretive to EPS.

>> 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 strengthens its number 1 market share in
   Cayuga County.

>> Provides an immediate presence in Ithaca with two branches and over $50
   million in deposits as of June 30, 2001. Adds to the previously announced
   opening of our first branch location in Tompkins County.

>> Significant opportunities for cost savings available.

>> Given our track record as an acquiror, we believe this to be a low risk
   transaction.

>> Finger Lakes has a complimentary loan portfolio, with a higher concentration
   of consumer and commercial loans than First Niagara.


[LOGO]

Transaction Economics
- --------------------------------------------------------------------------------

>> The Merger, exclusive of the "second step" offering, is accretive to First
   Niagara Financial Group's estimated EPS based on conservative, achievable,
   anticipated cost savings of approximately $4.25 million pre-tax by 6.7% in
   the first full year of the combination.

>> Revenue and Cross-Sell Enhancement opportunities exist, but are not factored
   into our Synergies.

>> Merger Related Charges of $6.2 Million after-tax.

>> On a Per Share Equivalent Basis, Finger Lakes shareholders will incur
   significant accretion in earnings and book value. Finger Lakes shareholders
   also receive a significant dividend increase.

>> Enhanced market presence due to the increase in asset size.

>> Increased market liquidity, and a broader ownership base help to limit
   volatility and possibly increase valuation multiples.
