An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Plan at December 31, 2005, and the changes in its net assets available for plan benefits for the year then ended, in conformity with accounting principles generally accepted in the United States.

The accompanying supplemental schedule of assets held for investment as of December 31, 2005 is presented for purposes of additional analysis and is not a required part of the financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974.

DESCRIPTION OF PLAN The following description of the First Niagara Financial Group 401(k) Plan (the Plan) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan's provisions. General The plan is a defined contribution plan with salary reduction features as permitted under Section 401(k) of the Internal Revenue Code. The Plan is funded by employee and employer contributions and covers substantially all eligible employees of First Niagara Bank and its Subsidiaries, which is owned by First Niagara Financial Group, Inc. (collectively, the Company). It is intended to conform with the provisions of the Employee Retirement Income Security Act of 1974 (ERISA) and subsequent legislation, when applicable. At December 31, 2005 the assets of the Plan are maintained in investment funds held by Principal Life Insurance Company (Principal). Broker commissions associated with investment transactions and investment management fees are paid by the Plan. Administrative fees not paid by the Plan are paid by the Company. As a result of the acquisition of the sponsoring entities, the assets of Hudson River Bank and Trust Company 401(k) Savings Plan, C.W. Bostwick, Inc. 401(k) Plan, and Burke Group, Inc. 401(k) Plan were transferred into the Plan during 2005. The assets of Troy Savings Bank 401(k) Savings Plan were transferred into the Plan during 2004. Eligibility All eligible employees who have completed three months of service, as defined in the Plan, have attained the age of 21 and who are not represented by a collective bargaining unit are eligible to participate in the Plan. Contributions Employees who are eligible to participate in the Plan may elect to contribute up to 100% of their annual compensation, as defined in the Plan, subject to certain limitations. Employees who are age 50 or older by the end of the calendar year are allowed to make an additional "catch-up" contribution. This contribution was limited to $4,000 in 2005 and $3,000 in 2004. This limit was increased to $5,000 in 2006. The "catch-up" contribution is not subject to the employer matching contribution. The Company contributes a matching contribution to those participating employees who have elected to make employee contributions. The matching contribution is equal to 100% of an employee's contribution up to 2% of the employee's compensation (as defined in the Plan), plus 75% of an employee's contribution between 2% and 6% of the employee's compensation. Matching contributions for an employee shall not be more than 5% of the employee's compensation in a Plan year. 3 1. DESCRIPTION OF PLAN (Continued) Contributions (Continued) The Company may also make an annual discretionary contribution to the Plan. No discretionary contributions were made to the Plan during 2005 and 2004. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. Participants direct the investment of their contributions into various investment options offered by the Plan. Participants may change their investment allocation on a daily basis. Participant Accounts Each participant's account is credited with the participant's contribution and an allocation of (a) the Company's contributions, (b) Plan earnings and losses, and (c) administrative expenses. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. Vesting All participants are immediately 100% vested in their contributions, plus allocated earnings thereon. Participants vest in Company matching and discretionary contributions as follows: Less than 2 years 0% 2 years 20% 3 years 40% 4 years 60% 5 years 80% 6 years 100% Loans to Participants Participants may borrow from their accounts a minimum of $1,000 per loan up to a maximum amount, which is the lesser of $50,000 or 50% of their vested account balance. Loan terms range from 1-5 years or up to 15 years for the purchase of a principal residence. The loans are collateralized by the participant's account and bear interest at the rates available for comparable loans from commercial lending institutions. Principal and interest is paid ratably through payroll deductions. Payment of Benefits Employees are eligible for retirement benefits upon reaching age 65. Upon termination of service due to death, disability, or retirement, a participant or their beneficiary may elect to receive either a lump-sum amount equal to the value of the participant's vested interest in his or her account, or distributions based on various annuity options or fixed income payments. For termination of service for other reasons, a participant may receive the value of the vested interest in his or her account as a lump-sum distribution. Participating employees may take financial hardship withdrawals under prescribed circumstances, up to the value of their vested account balance. Forfeited Accounts Forfeitures of nonvested employer contributions may be used for Plan administrative expenses or to reduce the employer's future contributions. During 2005 and 2004, forfeitures used to reduce employer contributions amounted to $306,396 and $41,758, respectively. Unused forfeited account balances were $218,546 and $116,527 at December 31, 2005 and 2004, respectively. 4 1. DESCRIPTION OF PLAN (Continued) Plan Termination Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of plan termination, participants will become 100% vested in their accounts. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Accounting The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the United States. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Risks and Uncertainties The Plan's assets include various types of investment securities. Investment securities are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investments and the level of uncertainty related to the value of such investments, changes in the values of investments will occur and such changes could materially affect the amounts reported in the accompanying financial statements. Investments The investments in the guaranteed interest accounts, the pooled separate accounts, and the common collective trust are valued at fair values as determined by Principal. Investments in First Niagara Financial Group, Inc. common stock and mutual funds are valued based on quoted market prices. Participant loans are valued at their outstanding balances. The guaranteed interest accounts are non fully benefit responsive, since withdrawals prior to maturity for events other than death, disability, termination, or retirement may be subject to a surrender charge. As such, guaranteed interest accounts are recorded at fair value. The fair value of the Plan's guaranteed interest accounts approximates contract value. Purchases and sales of securities are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date. 3. INVESTMENTS Contributions to the Plan are invested under a group annuity contract with Principal, Gartmore Trust Company, Delaware Charter Guarantee and Trust Company, and also in First Niagara Financial Group, Inc. common stock.

TAX STATUS The Plan has received a determination letter from the Internal Revenue Service dated May 5, 2003, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Subsequent to this determination by the Internal Revenue Service, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan administrator believes that the Plan is being operated in compliance with the applicable requirements of the Code and therefore that the Plan, as amended, is qualified and the related trust is tax-exempt. 5. SUBSEQUENT EVENTS The Company acquired Hatch Leonard Naples, Inc. during 2005, and maintained their existing 401(k) plan through December 31, 2005. Effective January 1, 2006, employees of Hatch Leonard Naples, Inc. are eligible to participate in the Plan. The balances in the Hatch Leonard Naples, Inc. 401(k) plan are expected to be transferred into the Plan during 2006. In June 2006, Plan participants were notified by the Plan Administrator of the intention to change the Plan's recordkeeper and trustee. In connection with this change, participants will temporarily be unable to change investments in their individual accounts, to obtain a loan or distribution from the Plan, or to obtain a hardship withdrawal from the Plan. This change is not expected to have a material effect on the Plan's financial statements. 8 Schedule I FIRST NIAGARA FINANCIAL GROUP 401(k) PLAN SCHEDULE OF ASSETS HELD FOR INVESTMENT DECEMBER 31, 2005 - -------------------------------------------------------------------------------- Description of # of shares Current Identity of Issue Investment or units Value - -------------------------- -------------------------------------------------- ----------- ----------- Guaranteed Interest Accounts: ----------------------------- Principal Life * Maturity Date 12/31/05 $ 835,201 Insurance Company * Maturity Date 12/31/06 582,846 * Maturity Date 12/31/07 562,557 * Maturity Date 12/31/08 197,573 * Maturity Date 12/31/09 111,061 ----------- 2,289,238 Pooled Separate Accounts: ------------------------- Principal Life * Principal Bond and Mortgage Fund 6,452 4,747,249 Insurance Company * Principal Large Cap Stock Index Fund 82,308 3,875,115 * Principal Small Company Blend Fund 23,286 1,592,272 * Principal Medium Company Blend Fund 35,225 2,197,377 * Principal Diversified International Fund 64,895 3,203,032 * Principal Financial Group, Inc.
