               First Niagara Financial Group, Inc. and Subsidiary
              Notes to Condensed Consolidated Financial Statements
                                   (unaudited)

The accompanying condensed consolidated financial statements of First Niagara
Financial Group, Inc. ("FNFG") and its wholly owned subsidiary First Niagara
Bank ("First Niagara") have been prepared in accordance with U.S. generally
accepted accounting principles ("GAAP") for interim financial information and
the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly,
they do not include all of the information and footnotes required by GAAP for
full year financial statements. In the opinion of management, all adjustments
necessary for a fair presentation have been included. Results for the three
month period ended March 31, 2005 are not necessarily indicative of the results
that may be expected for the year ending December 31, 2005. Certain
reclassification adjustments were made to the 2004 financial statements to
conform them to the 2005 presentation. FNFG and its consolidated subsidiary are
hereinafter referred to collectively as the "Company."

(1)   Stock-Based Compensation

The Company maintains various long-term incentive stock benefit plans under
which fixed award stock options and restricted stock may be granted to certain
directors and key employees. The Company has continued to apply the intrinsic
value-based method of accounting prescribed by Accounting Principles Board
("APB") Opinion No. 25, "Accounting for Stock Issued to Employees," and has only
adopted the disclosure requirements of Statement of Financial Accounting
Standards ("SFAS") No. 123, "Accounting for Stock-Based Compensation," as
amended by SFAS No. 148, "Accounting for Stock-Based Compensation - Transition
and Disclosure - An Amendment of FASB Statement No. 123." As such, compensation
expense is recorded on the date the options are granted only if the current
market price of the underlying stock exceeded the exercise price. Compensation
expense related to restricted stock awards is based upon the market value of
FNFG's stock on the grant date and is accrued ratably over the required service
period.

Had the Company determined compensation cost based on the fair value method
under SFAS No. 123, net income would have been reduced to the pro forma amounts
indicated below. These amounts may not be representative of the effects on
reported net income for future years due to changes in market conditions and the
number of options outstanding (in thousands, except per share amounts):

In December 2004, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 123R "Share Based Payment," which revised SFAS No. 123 and superseded APB
Opinion No. 25. More specifically, this Statement requires companies to
recognize in the income statement, over the required service period, the
estimated grant-date fair value of stock options and other equity-based
compensation issued to employees and directors using option pricing models. This
Statement is effective for the Company's first annual period beginning after
June 15, 2005 and the Company has chosen to apply the modified prospective
approach. Accordingly, awards that are granted, modified or settled after
January 1, 2006 will be accounted for in accordance with SFAS No. 123R and any
unvested equity awards granted prior to that date will continue to be recognized
in the income statement as service is rendered based on their grant-date fair
value calculated in accordance with SFAS No. 123.

(2)   Acquisition

Hudson River Bancorp, Inc.

On January 14, 2005, FNFG acquired all of the outstanding common shares of
Hudson River Bancorp, Inc. ("HRB"), and its wholly-owned subsidiary Hudson River
Bank & Trust Company. Following completion of the acquisition, HRB's fifty
branch locations were merged into First Niagara's branch network.

The aggregate purchase price of $615.7 million included the issuance of 35.7
million shares of FNFG stock (valued at $13.552 per share), cash payments
totaling $126.8 million and capitalized costs related to the acquisition,
primarily investment banking and professional fees, of $4.4 million. This
acquisition was accounted for under the purchase method of accounting. The
results of HRB's operations were included in the 2005 consolidated statement of
income from the date of acquisition.

The following table summarizes the estimated fair values of the assets acquired
and liabilities assumed at the date of acquisition (in thousands):

                 Net assets acquired                            $  615,694
                                                                ==========

As a result of the implementation of Statement of Position ("SOP") 03-3,
"Accounting for Certain Loans or Debt Securities Acquired in a Transfer," which
was effective January 1, 2005, loans acquired from HRB with evidence of a
deterioration of credit quality since origination that the Company believes it
will not collect all contractually required payments are being carried at
estimated net realizable value. Those loans had an outstanding balance and
carrying value of $24.8 million and $14.9 million, respectively, at March 31,
2005 and an accretable yield related of approximately $2.2 million. Accordingly,
the amount of HRB's historical allowance for credit losses at acquisition date
was reduced by approximately $10.0 million.

The core deposit and other intangible assets acquired are being amortized using
the double declining balance method over their estimated useful-life of 10
years. The goodwill was primarily assigned to the Company's banking segment of
which none is deductible for tax purposes.

The following table presents unaudited pro forma information as if the
acquisition of HRB had been consummated as of the beginning of the 2004 first
quarter. Pro forma information for 2005 is not presented since such results were
not materially different from actual results. This pro forma information gives
effect to certain adjustments, including purchase accounting fair value
adjustments, amortization of core deposit and other intangibles and related
income tax effects. The pro forma information does not necessarily reflect the
results of operations that would have occurred had the Company acquired HRB at
the beginning of 2004. In particular, cost savings and $2.3 million of indirect
merger and integration costs are not reflected in the pro forma amounts (in
thousands, except per share amounts):

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations

This Quarterly Report on Form 10-Q may contain certain forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended,
that involve substantial risks and uncertainties. When used in this report, or
in the documents incorporated by reference herein, the words "anticipate",
"believe", "estimate", "expect", "intend", "may", and similar expressions
identify such forward-looking statements. Actual results, performance or
achievements could differ materially from those contemplated, expressed or
implied by the forward-looking statements contained herein. These
forward-looking statements are based largely on the expectations of the
Company's management and are subject to a number of risks and uncertainties,
including but not limited to, economic, competitive, regulatory, and other
factors affecting the Company's operations, markets, products and services, as
well as expansion strategies and other factors discussed elsewhere in this
report and other reports filed by the Company with the Securities and Exchange
Commission ("SEC"). Many of these factors are beyond the Company's control.

Overview

Total assets increased to $7.9 billion at March 31, 2005 from $5.1 billion at
December 31, 2004. The acquisition of HRB in January 2005 added $1.69 billion of
loans, 31% of which were commercial mortgage and business loans, and $1.78
billion of deposits, 68% of which were core accounts. Loan growth also included
a $50.9 million, or 10% annualized, organic increase in commercial real-estate
and business loans. The Company continued to deepen customer relationships as
called for in its strategic plan, including the introduction of relationship
deposit products. These initiatives contributed to the 5% annualized organic
growth in deposits during the quarter.

Net income for the quarter ended March 31, 2005 increased to $21.1 million, or
$0.19 per diluted share from $11.9 million, or $0.15 per diluted share for the
same period of 2004. The 2005 results included a $23.6 million or 65% increase
in net interest income and a 20 basis point improvement in net interest margin
over the prior year quarter. Credit quality remained very strong during the 2005
first quarter as annualized net charge-offs amounted to 0.13% of average loans
and non-performing assets continued at low levels. Accordingly, the Company set
aside a provision for credit losses of $2.3 million. Increases in both
noninterest income and expense reflect the impact of the acquisition of HRB in
January 2005, as well as the continuing expansion of existing operations. That
includes the addition of three new branches, an insurance agency and a leasing
company since the 2004 first quarter. Additionally, noninterest income continues
to benefit from higher banking services income, as consumers become more
comfortable with debit card usage and conducting banking activities
electronically, while noninterest expenses reflect the Company's continuous
investment in its infrastructure and implementation of its strategic plan.

Critical Accounting Estimates

Management of the Company evaluates those accounting estimates that are judged
to be critical - those most important to the portrayal of the Company's
financial condition and results, and that require management's most difficult,
subjective and complex judgments. Management considers the accounting estimates
relating to the adequacy of the allowance for credit losses and the analysis of
the carrying value of goodwill for impairment to be critical. The judgments made
regarding the allowance for credit losses and goodwill can have a material
effect on the results of operations of the Company. A more detailed description
of the Company's methodology for calculating the allowance for credit losses and
assumptions made is included within the "Lending Activities" section filed in
Part I, Item 1, "Business" of the Company's 2004 10-K dated March 14, 2005. A
more detailed description of the Company's methodology for testing goodwill for
impairment and assumptions made is included within the "Critical Accounting
Estimates" section filed in Part II, Item 7, "Management's Discussion and
Analysis of Financial Condition and Results of Operations" of the Company's 2004
10-K dated March 14, 2005.

Lending Activities

Total loans and leases outstanding increased $1.74 billion from December 31,
2004 to March 31, 2005. That includes $1.69 billion of loans from the
acquisition of HRB in January 2005, which added $984.2 million of residential
mortgages, $97.2 million of home equity loans, $414.1 million of commercial
mortgages, $104.5 million of commercial business loans and $18.8 million of
consumer loans. Additionally, the HRB portfolio included $39.5 million of
financed insurance premiums and $35.3 million of manufactured housing loans,
which the Company is managing within its specialized lending operations. During
the quarter, the Company's continuing emphasis on commercial lending resulted in
a $38.4 million, or 9% annualized increase in commercial real estate loans, from
December 31, 2004, while commercial business loans increased $12.5 million, or
11% annualized, during the same period. That level of growth is consistent with
the Company's targeted internal commercial loan growth of 10% for 2005. Another
highlight for the quarter was the reversal of the residential mortgage pay-off
trend seen over the past few years during the challenging refinance rate
environment. This positive development is attributed to the Company's decision
to outsource residential loan originations in the Eastern region of New York
State and various other strategic initiatives, which are expected to continue to
benefit this portfolio in future periods.

- ----------
(1)   Includes commercial leases, financed insurance premiums and manufactured
      housing loans.

During the first quarter of 2005, credit quality remained strong as annualized
net loan charge-offs were 0.13% of average loans, which is the Company's lowest
level in over three years. Non-performing assets increased modestly to 0.27% of
total assets at March 31, 2005 from 0.25% of total assets at December 31, 2004.
However, excluding the non-performing assets related to the financed insurance
premiums and manufactured housing loan portfolios acquired from HRB, this
percentage was comparable to the 2004 year-end level. The increase in the ratio
of the allowance for credit losses to total loans of 1.27% at December 31, 2004
to 1.46% at March 31, 2005 reflects the impact of the acquisition of HRB,
including the allowance related to the financed insurance premiums and
manufactured housing loan portfolios acquired, that typically carry a higher
loss percentage, as well as the continuing growth in larger balance, higher risk
commercial real estate and business loans, which are still relatively
unseasoned. The ratio of the allowance for credit losses to non-accruing loans
of 363% at March 31, 2005, compares to 344% at December 31, 2004.

While management uses available information to recognize losses on loans, future
credit loss provisions will be necessary based on numerous factors, including
changes in economic conditions. In addition, various regulatory agencies, as an
integral part of their examination process, periodically review the allowance
for credit losses and may require the Company to recognize additional provisions
based on their judgment of information available to them at the time of their
examination. To the best of management's knowledge, the allowance for credit
losses includes all losses at each reporting date that are both probable and
reasonable to estimate. However, there can be no assurance that the allowance
for credit losses will be adequate to cover all losses that may in fact be
realized in the future or that additional provisions for credit losses will not
be required.

Investing Activities

The Company's securities available for sale increased to $1.74 billion at March
31, 2005 from $1.17 billion at December 31, 2004. This reflects the $591.6
million of investment securities acquired from HRB, which had a weighted average
life of 2.6 years, including $362.8 million of mortgage-backed securities. The
Company's investment portfolio remains positioned to provide a stable source of
earnings while limiting earnings volatility, as the weighted average life of the
Company's securities available for sale at March 31, 2005 was 2.3 years.

Funding Activities

Deposits. The increase in deposits from December 31, 2004 includes a total of
$1.78 billion acquired from HRB, including $602.6 million of savings accounts,
$371.2 million of interest bearing checking accounts, $570.2 million of
certificates of deposit and $234.9 million of noninterest bearing deposits.
During the first quarter, the Company continued to focus on deepening customer
relationships and executing its customer centric strategic initiatives. As a
result, organic growth of $59.1 million from December 31, 2004 was realized,
primarily in relationship money market and relationship certificates of deposit
accounts, as well as municipal deposits. The certificate accounts brought with
them new checking relationships, which the Company anticipates will drive core
deposit growth as those accounts mature. Going forward, deposit growth will also
benefit from the Company's de novo branch expansion strategy which calls for the
opening of up to eight new branches in 2005. During the first quarter, leases
were signed for seven of those locations. The Company continues to prioritize
its deposit gathering and retention efforts given the low growth and
competitiveness of its markets and the importance of low cost funds in managing
net interest margin. A nominal outflow of HRB retail deposits was experienced
during the quarter, which amounted to only 1% of the acquired balance, due
primarily to the Company's decision to adjust interest rates and fees on certain
accounts to be more in line with the Company's pricing policies.

Company's deposits in dollar amounts and in percentages as of the dates

Borrowings. Borrowed funds totaled $1.24 billion at March 31, 2005 compared to
$750.7 million at December 31, 2004. Excluding the $371.6 million assumed in the
HRB acquisition, the additional $113.6 million of borrowings were used to fund
commercial loan growth and the cash portion of the HRB acquisition.


                                       15


Equity Activities

Stockholders' equity increased to $1.39 billion at March 31, 2005 compared to
$928.2 million at December 31, 2004. The HRB acquisition included the issuance
of 35.7 million shares of common stock with an aggregate value of $484.5
million. During the first quarter of 2005, common stock dividends declared of
$0.09 per share totaled $10.3 million, which represents a 29% increase over the
prior year first quarter and equated to a 47% payout ratio.

The Company repurchased 1.8 million of its shares during the first three months
of 2005 at an average cost of $13.48 per share. As of March 31, 2005, the
Company has repurchased 2.4 million of the 4.2 million buy-back program
announced in the third quarter of 2004. The extent to which shares are
repurchased in the future will depend on a number of factors including market
trends and prices, economic conditions, and alternative uses for capital.
However, the Company anticipates repurchasing the remaining 1.8 million shares
under the current authorization by the end of the second quarter of 2005.

Results of Operations for the Three Months Ended March 31, 2005 and March 31,
2004

Net Interest Income

Net interest margin improved to 3.76% during the first quarter of 2005, compared
to 3.56% for the same period of 2004. This improvement reflects the higher
yielding net earning assets acquired from HRB, as well as the growth of the
commercial real estate and business loan portfolios and increases in
non-interest bearing deposits. The Company expects its net interest margin to
gradually tighten for the remainder of 2005 as the flattening yield curve and
increasingly competitive deposit pricing impact the pricing on interest bearing
assets and liabilities. The Company anticipates that its full year net interest
rate margin will be approximately 3.70%.

In addition to the impact of a $2.3 billion increase in average interest earning
assets, due primarily to the acquisition of HRB, the Company's interest income
benefited from a 27 basis point improvement in the yield earned on those assets
as a result of the higher yields on assets acquired from HRB and the recent rise
in short-term rates which caused the yield on the Company's variable-rate assets
and short-term investment securities portfolio to increase.

The increase in interest expense during the 2005 first quarter resulted from a
$2.0 billion increase in average interest bearing liabilities, due primarily to
the deposits and borrowings assumed in the HRB acquisition. The continuing
pay-off of higher rate borrowings contributed to the yield on borrowed funds
declining from 4.07% in 2004 compared to 3.62% in the 2005 period. However, the
benefit of that decrease on the average rate paid on interest-bearing
liabilities was mitigated by the recent rise in short-term rates and competitive
deposit pricing.

Provision for Credit Losses

During the quarter, the Company set aside a $2.3 million provision for credit
losses. This provision is based upon management's continuous assessment of the
adequacy of the allowance for credit losses with consideration given to such
interrelated factors as the composition and risk in the loan portfolio, the
level of non-accruing and delinquent loans and related collateral or government
guarantees, charge-offs and both current and historic economic conditions. The
Company establishes provisions for credit losses, which are charged to
operations, in order to maintain the allowance for credit losses at a level to
absorb credit losses in the existing loan portfolio.

Noninterest Income

For the first quarter of 2005, the Company earned $18.4 million of noninterest
income compared to $11.9 million for the same period of 2004. This increase
reflects the benefit of the HRB transaction, which added approximately $4.9
million in fee income during the quarter. Additionally, core banking services,
risk management, and mutual fund and annuity revenue have increased as a result
of the continuing implementation of the Company's business model across its
franchise as well as the addition of three new branches, an insurance agency and
a leasing Company since the 2004 first quarter. Noninterest income also
continues to benefit from higher banking services income, as consumers become
more comfortable with debit card usage and conducting banking activities
electronically.


                                       16


Noninterest Expense

Noninterest expense increased $15.3 million over the 2004 first quarter due
primarily to the operating costs associated with the 44 former HRB branches, as
well as three new branch locations, an insurance agency and a leasing Company
added since the 2004 first quarter. Additionally, the 2005 quarter includes $2.3
million of merger related expenses, compared to $1.1 million for the 2004 first
quarter, as well as costs related to the implementation of the Company's
strategic planning initiative and commercial lending and financial services
business growth. Even with these increases, the Company's efficiency ratio of
56% for the first quarter of 2005 improved when compared to the 59% for the
prior year period. Excluding merger related expenses, the efficiency ratio was
53% for the 2005 period.

Income Taxes

The effective tax rate of 35.1% for the current quarter increased from the first
quarter of 2004 rate of 34.3%, as the HRB assets acquired generated less tax
advantaged income than the Company's existing assets. The above effective tax
rates include the benefit of excluding 60% of the dividends paid to First

income tax purposes. The legislation to eliminate this benefit in the proposed
2005 New York State budget was not enacted.

Liquidity and Capital Resources

In addition to cash flow from operations, deposits and borrowings, funding is
provided from the principal and interest payments received on loans and
investment securities. Additionally, the Company sells longer-term fixed rate
mortgage loans in the secondary market. While maturities and scheduled
amortization of loans and securities are predictable sources of funds, deposit
balances and mortgage prepayments are greatly influenced by the level of
interest rates, economic environment and local competitive conditions.

The Company's primary investing activities are the origination of loans and the
purchase of investment securities. During the first three months of 2005, loan
originations totaled $371.5 million compared to $217.9 million for the same
period of 2004, while purchases of investment securities totaled $125.8 million
during the 2005 period compared to $257.1 million for the 2004 period. The
increase in loan originations is a result of increased lending activity due to
the HRB acquisition and continuing growth in the commercial portfolio. The
investment security purchases in 2004 primarily relate to the investment of the
remainder of the Company's second-step stock offering proceeds.

During the first quarter of 2005, cash flows provided by securities available
for sale amounted to $129.5 million compared to $139.5 million for the same
period in 2004. Deposit growth and borrowings, excluding those acquired from
HRB, provided $174.2 million of additional funding for the three months ended
March 31, 2005. The Company has a total of $760.5 million available under
existing lines of credit with the Federal Home Loan Bank, Federal Reserve Bank
and a commercial bank that may be used to fund lending activities, liquidity
needs and/or to adjust and manage the asset and liability position of the
Company.

In the ordinary course of business, the Company extends commitments to originate
residential, commercial and other loans. Commitments to extend credit are
agreements to lend to a customer as long as there is no violation of any
condition established in the contract. Commitments generally have fixed
expiration dates or other termination clauses and may require payment of a fee.
Since the Company does not expect all of the commitments to be funded, the total
commitment amounts do not necessarily represent future cash requirements. The
Company evaluates each customer's creditworthiness on a case-by-case basis.
Collateral may be obtained based upon management's assessment of the customers'
creditworthiness. Commitments to extend credit may be written on a fixed rate
basis exposing the Company to interest rate risk given the possibility that
market rates may change between the commitment date and the actual extension of
credit. As of March 31, 2005, the Company had outstanding commitments to
originate residential real estate, commercial real estate and business, and
other consumer loans of approximately $273.7 million, which generally have an
expiration period of less than 120 days. Commitments to sell residential
mortgages amounted to $6.8 million at the end of the first quarter.

The Company extends credit to consumer and commercial customers, up to a
specified amount, through lines of credit. The borrower is able to draw on these
lines as needed, thus the funding requirements are generally more difficult to
predict. Unused commercial lines of credit amounted to $389.1 million at March
31, 2005 and generally have an expiration period of less than one year. Home
equity and other consumer lines of credit totaled $167.9 million and have an
expiration period of up to ten years. In addition to the above, the Company
issues standby letters of credit to third parties that guarantee payments on
behalf of commercial customers in the event the customer fails to perform under
the terms of the contract between the customer and the third-party. Standby
letters of credit amounted to $60.8 million at March 31, 2005 and generally have
an expiration period greater than one year. Since the majority of unused lines
of credit and outstanding standby letters of credit expire without being funded,
the Company's obligation under the above commitment amounts is substantially
less than the amounts reported. It is anticipated that there will be sufficient
funds available to meet the current loan commitments and other obligations
through the sources described above. The credit risk involved in issuing these
commitments is essentially the same as that involved in extending loans to
customers and is limited to the contractual notional amount of those
instruments.

Cash, interest-bearing demand accounts at correspondent banks, federal funds
sold, and other short-term investments are the Company's most liquid assets. The
level of these assets are monitored daily and are dependent on operating,
financing, lending and investing activities during any given period. Excess
short-term liquidity is usually invested in overnight federal funds sold. In the
event that funds beyond those generated internally are required due to higher
than expected loan commitment fundings, deposit outflows or the amount of debt
being called, additional sources of funds are available through the use of
repurchase agreements, the sale of loans or investments or the Company's various
lines of credit. As of March 31, 2005, the total of cash, interest-bearing
demand accounts, federal funds sold and other money market investments was
$107.8 million.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Interest rate risk occurs when assets and liabilities reprice at different times
as interest rates change. The Company monitors this interest rate sensitivity
through the use of a net interest income model, which estimates changes in net
interest income over a range of interest rate scenarios.

The Asset and Liability Committee, which is comprised of members of senior
management, monitors the Company's interest rate sensitivity. Management takes
actions to mitigate exposure to interest rate risk through the use of on- or
off-balance sheet financial instruments including, but not limited to, changes
in the pricing of loan and deposit products, modifying the composition of
interest-earning assets and interest-bearing liabilities, and the use of
interest rate derivatives. As of March 31, 2005, the Company's off-balance sheet
financial instruments were comprised only of customer lines and letters of
credit, and commitments to originate and sell loans which were entered into in
the ordinary course of business. See Liquidity and Capital Resources for further
description of these items.

The accompanying table as of March 31, 2005 sets forth the estimated impact on
the Company's net interest income for the next twelve months resulting from
potential changes in the interest rates. These estimates require making certain
assumptions including loan and mortgage-related investment prepayment speeds,
reinvestment rates, and deposit maturities. These assumptions are inherently
uncertain and, as a result, the Company cannot precisely predict the impact of
changes in interest rates on net interest income. Actual results may differ
significantly due to timing, magnitude and frequency of interest rate changes
and changes in market conditions. The HRB acquisition did not materially impact
the Company' interest rate risk exposure. Given the very limited projected
impact of interest rate changes on net interest income, as shown below,
management believes that the Company remains interest rate "neutral" at March
31, 2005 (dollars in thousands):

Item 4. Controls and Procedures

Under the supervision and with the participation of the Company's management,
including the Chief Executive Officer and Chief Financial Officer, the Company
has evaluated the effectiveness of the design and operation of its disclosure
controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the
Exchange Act) as of the end of the period covered by this quarterly report.
Based upon that evaluation, the Chief Executive Officer and Chief Financial
Officer concluded that, as of the end of the period covered by this quarterly
report, the Company's disclosure controls and procedures are effective to ensure
that information required to be disclosed in the reports that the Company files
or submits under the Securities Exchange Act of 1934 is recorded, processed,
summarized and reported, within the time periods specified in the Securities and
Exchange Commission's rules and forms. There has been no change in the Company's
internal control over financial reporting during the most recent fiscal quarter
that has materially affected, or is reasonably likely to materially affect, the
Company's internal control over financial reporting.

(1)   In July 2003 the Company announced a program to repurchase up to 2,107,161
      shares of its outstanding common stock in order to fund the Company's
      vested stock options at that time. This program was completed in the
      fourth quarter of 2004 at an average cost of $13.44 per share. On August
      31, 2004, the Company announced an additional 4,200,000 share stock
      repurchase program to supplement that authorization. This program does not
      have an expiration date. As of March 31, 2005, the average cost of the
      2,391,139 shares repurchased under the current program was $13.68 per
      share. The extent to which shares are repurchased will depend on a number
      of factors including market trends and prices, economic conditions, and
      alternative uses for capital.

      In addition to the above purchases, during the first quarter of 2005, the
      Company repurchased 1,480 shares from executives of the Company at an
      average cost of $13.31 per share to satisfy minimum tax withholding
      requirements on vested restricted shares as allowed under the Company's
      restricted stock plans. The price of these repurchases is based upon the
      closing market price of the Company's stock on the date of vesting.
