    FIRST NIAGARA FINANCIAL GROUP, INC. REPORTS AN 85% INCREASE IN NET INCOME
                       OVER THE PRIOR YEAR SECOND QUARTER

Lockport, N.Y. - July 15, 2005 - First Niagara Financial Group, Inc. (NASDAQ:
FNFG), today announced that net income for second quarter of 2005 increased to
$24.1 million, or $0.22 per diluted share from $13.0 million, or $0.16 per
diluted share for the same period of 2004. This represents an 85% increase in
net income and a 38% increase in diluted earnings per share over the prior year
second quarter. Compared to the first quarter of 2005, net income increased 14%.

First Niagara President and CEO Paul J. Kolkmeyer stated, "Second quarter
results were very good, reflecting the benefits of the continuing expansion of
our commercial loan portfolio and deposit base, the ongoing integration of
Hudson River Bancorp, acquired in January of this year, and the initial
implementation of our Strategic Blueprint. The growth of our core businesses,
combined with exceptional credit quality, were key contributors to our strong
financial performance. During the quarter we continued to make significant
enhancements to our infrastructure in order to support our strategy of providing
relationship based solutions to meet our customers' financial needs, which in
turn will drive future performance improvements."

As anticipated, the Company's net interest rate margin began to tighten during
the quarter to 3.72% compared to 3.76% for the linked quarter. Net interest
income increased 6% to $63.6 million, primarily due to a combination of strong
commercial real estate and business loan growth, as well as the net earning
assets acquired from Hudson River. Total loans increased $83.8 million during
the second quarter, including 13% annualized growth in commercial real estate
and business loans and 12% annualized growth in home equity loans. During the
quarter, credit quality trends further improved as annualized net charge-offs
fell to 0.07% of average total loans, their lowest level in nearly five years
and almost half the 0.13% for the linked quarter. In addition, non-performing
assets improved to 0.25% of total assets from 0.27% at the end of March. As a
result, a $900 thousand provision for credit losses was recorded compared to
$2.3 million for the first quarter of 2005. The ratio of the allowance for
credit losses to total loans and non-performing loans was 1.43% and 382%,
respectively at June 30, 2005.

Deposits increased $73.3 million from March 31, 2005, which is equivalent to a
6% annualized growth rate. This growth continues to be driven by relationship
based products and deposit gathering and retention initiatives introduced as
part of the Company's Strategic Blueprint. The Company anticipates that opening
these new accounts will drive future deposit and revenue growth as they mature.
Also noteworthy during the quarter is that retail deposits at the former Hudson
River branches now exceed acquired levels.

For the second quarter of 2005, the Company had $20.4 million of noninterest
income, which includes the benefits of the Hudson River integration and the
Company's efforts to fully implement its financial services business model
throughout its branch network. This resulted in an 18% increase in banking
services income and, combined with the two insurance agency acquisitions since
the beginning of the year, led to a 5% increase in risk management income.
Wealth management revenue for the quarter was consistent with the first quarter
of 2005 as the benefit of Hudson River was offset by reduced demand for annuity
products due to the challenging interest rate environment.

Noninterest expense for the second quarter was $46.2 million versus $43.9
million for the linked quarter. This increase is primarily attributable to
having a full quarter of expenses from the former Hudson River operations and
employee contract termination payments. Additionally, marketing expenses
increased from first quarter levels as a result of the Company's spring home
equity and business banking promotions. Nonetheless, the Company's efficiency
ratio improved to 55% during the current quarter versus 56% for the linked
quarter.



During the three months ended June 30, 2005, the Company repurchased an
additional 2.5 million shares of its common stock compared to 1.8 million shares
during the first quarter. As of quarter-end, 5.1 million shares remain available
for repurchase under the 5.8 million authorization approved in May. The extent
to which shares are repurchased will continue to depend on a number of factors
including market trends and prices and alternative uses for capital.

Outlook - "Given the results of the first two quarters, we believe that 2005
GAAP earnings per diluted share will be between $0.83 and $0.84 per share, which
includes $0.01 per share of Hudson River merger expenses," stated Executive Vice
President and Chief Financial Officer, John R. Koelmel. "Our current estimate
takes into consideration our expectation that the yield curve will continue to
flatten, net charge-offs will begin to move towards more normalized levels and
the recently announced acquisition of the Hatch Leonard Naples, Inc. insurance
agency will be neutral to earnings for the remainder of 2005. While our net
interest margin will continue to tighten in the second half of the year, we
remain comfortable with our previous guidance for a margin of approximately
3.70% for the full year. We are confident that the on-going implementation of
our Strategic Blueprint provides the foundation for achieving these results and
will continue to drive earnings growth into 2006."
