1.    Assumes the Merger was completed on January 1, 2004. Historical amounts
      for First Niagara and Hudson River are for the twelve-month period ended
      December 31, 2004 and September 30, 2004, respectively, which are the most
      recently reported amounts.

2.    Purchase accounting adjustments, representing market valuation premiums
      and discounts attributable to the Merger, for loans and securities
      available for sale are amortized using the double declining balance method
      over their estimated lives while those related to deposits and borrowings
      are amortized based upon their expected cash flows. The core deposit and
      other intangible assets acquired are generally being amortized using the
      double declining balance method over their useful-life of approximately 11
      years. The estimated increase(decrease) on pre-tax income of these
      purchase accounting adjustments for the five years succeeding the Merger
      are as follows (in thousands):

3.    Reflects the $1.7 million reduction in interest income resulting from the
      decrease in earning assets due to the cash portion of the Merger purchase
      price ($46.8 million) and the direct costs of the Merger ($21.4 million),
      partially offset by the repayment of Hudson River's ESOP loan ($10.5
      million). These funds were assumed to have a pre-tax rate of 2.86% for the
      year ended December 31, 2004, which represents the actual yield earned on
      First Niagara's investment securities during that period.

4.    Reflects the $2.9 million increase in interest expense relating to the
      $80.0 million of additional borrowings used to fund a portion of the
      Merger purchase price. These funds were assumed to have a pre-tax rate of
      3.59% for the year ended December 31, 2004, which represents the actual
      yield on those borrowings.

5.    Noninterest income does not reflect revenue enhancement opportunities.

6.    Noninterest expense does not reflect anticipated cost savings.

7.    Includes actual pre-tax merger and integration costs totaling $3.2 million
      incurred by First Niagara and Hudson River in connection with the Merger.

8.    Reflects the tax effect of the pro forma adjustments using First Niagara's
      statutory tax rate of 40%.

9.    Reflects the additional 35.7 million shares issued in connection with the
      Merger.
