        FIRST NIAGARA FINANCIAL GROUP REPORTS NET INCOME OF $24.2 MILLION
                      FOR THE THIRD QUARTER OF 2005, UP 81%

Lockport, N.Y. - October 14, 2005 - First Niagara Financial Group, Inc. (NASDAQ:
FNFG), today announced that net income for the third quarter of 2005 increased
to $24.2 million, or $0.22 per diluted share from $13.3 million, or $0.17 per
diluted share for the same period of 2004. This represents an 81% increase in
net income and a 29% increase in diluted earnings per share over the prior year
third quarter. Net income and earnings per share were consistent with the linked
quarter.

"Another quarter of solid performance," stated President and CEO Paul J.
Kolkmeyer "was driven by our ongoing focus on meeting the financial needs of our
customers, which again resulted in strong loan and deposit growth. We also
continue to benefit from a diversified financial services business model, which
contributes to earnings growth by minimizing the impact of narrowing net
interest margins. We remain confident this strategy will enable us to grow and
expand our customer relationships and further drive our business expansion for
the remainder of the year and into 2006."

Net interest income of $63.5 million was consistent with the linked quarter, as
the benefits of 6% net earning asset growth was offset by additional tightening
of the Company's net interest margin to 3.69%. The margin continues to be
impacted by a combination of the flat yield curve, market pressures on loan
spreads and the change in deposit funding mix towards higher cost certificates.
During the quarter, total loans increased $95.5 million, including a 7%
annualized increase in commercial real estate and business loans and an 8%
increase in home equity loans. Also during the quarter, the Company's
residential real estate loans increased 4% on an annualized basis primarily in
short-term fixed and variable rate loans, which are the products the Company
holds in portfolio.

During the third quarter the Company continued to benefit from a favorable
credit environment. As a result, $1.6 million, or 0.13% of average loans, was
provided for credit losses during the three month period. Non-performing assets
were 0.29% of total assets at month-end, compared to 0.25% at the end of the
prior quarter. The ratio of the allowance for credit losses to total loans and
non-performing loans was 1.40% and 323%, respectively at September 30, 2005. Net
charge-offs amounted to 0.17% of average total loans during the quarter and
0.13% year to date, below the levels seen over the last several years.

Deposits increased $99.2 million from June 30, 2005, which is equivalent to a 7%
annualized growth rate. This expansion continues to be driven by relationship
based products as well as deposit acquisition and retention initiatives pursuant
to the Company's strategic plan.

For the quarter, noninterest income totaled $25.6 million, including $3.3
million of revenues from the Hatch Leonard Naples and Burke Group acquisitions
and a $1.4 million gain from the sale of the Company's ownership interest in a
real estate joint venture. Additionally, ongoing efforts to more fully implement
the Company's financial services business model throughout its branch network
resulted in a 7% increase in banking services revenue and a 9% increase in
lending and leasing income. As a result, noninterest income represented 28% of
total net revenues (the sum of net interest income and non interest income),
excluding the joint venture gain, versus 24% for the linked quarter.

Noninterest expense for the third quarter increased to $47.8 million, including
$3.2 million of operating expenses, primarily salaries and benefits,
attributable to Hatch Leonard Naples and the Burke Group. However, as a result
of the Company's continuing focus on increasing its operating leverage by
growing revenues, the efficiency ratio improved to 54.5%, excluding the joint
venture gain, compared to 55.0% for the linked quarter.



The effective tax rate for the current quarter was 39.1% compared to 34.7% for
the linked quarter. The increase was the result of a $1.4 million tax charge
relating to the surrender of $40 million of acquired bank owned life insurance.
Excluding this one-time charge, the effective tax rate was 35.5%.

For the three months ended September 30, 2005, the Company repurchased an
additional 1.0 million shares of its common stock, which brings the total shares
purchased in 2005 to 5.3 million. As of quarter-end, 4.1 million shares remain
available for repurchase under the current 5.8 million authorization. The extent
to which shares are repurchased will continue to depend on a number of factors
including market trends and prices as well as alternative uses for capital.

Outlook - "Given the results of the first three quarters, we are comfortable
with the current consensus estimate of $0.85 per diluted share for 2005," stated
Executive Vice President and Chief Financial Officer, John R. Koelmel. "Our
current forecast takes into consideration the expectation that the yield curve
will remain flat, and that our net interest margin will tighten somewhat further
for the remainder of the year. However, we anticipate that the impact of the
margin compression will be minimized by the benefits of our continuing loan and
deposit growth, strong credit quality, and expansion of our diversified
financial services businesses."
