Independent Registered Public Accounting Firm ------------------------------------------------------- To the Participants and Administrator of the Ecology and Environment, Inc. 401(k) Plan Lancaster, New York We have audited the accompanying statements of net assets available for benefits of Ecology and Environment, Inc. 401(k) Plan as of December 31, 2005 and 2004, and the related statements of changes in net assets available for benefits for the years then ended and the supplemental schedule of assets (held at end of year) as of December 31, 2005. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide 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 benefits of the Plan as of December 31, 2005 and 2004, and the changes in net assets available for benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets (held at end of year) as of December 31, 2005 is presented for the purpose of additional analysis and is not a required part of the basic 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. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/Schneider Downs & Co., Inc.

Page 4 ------ Ecology and Environment, Inc. 401(k) Plan Notes to Financial Statements December 31, 2005 and 2004 ---------------------------------------------------------------------------- 1. Description of Plan ------------------- The following description of the Ecology and Environment 401(k) Plan (the Plan) is provided for general information purposes only. Participants should refer to the Plan agreement for a more comprehensive description of the Plan's provisions. General ------- The Plan was established January 1, 1994 as a defined-contribution plan to cover all eligible employees of Ecology and Environment, Inc. (the Company). Beginning August 1, 2002 the hours of service requirement was eliminated and employees age twenty-one or older are immediately eligible to participate in the plan during the month following their date of hire. Contributions to the Plan were not permitted prior to July 1, 1994. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974. Contributions ------------- Participants may elect to make voluntary contributions subject only to the limitations of the Internal Revenue Code. The elective deferral percentage may be modified the first day of any month. Upon enrollment in the Plan, a participant may direct their contributions in any combination of the seventeen investment options in at least 10 percent increments in each option selected. The Company may make contributions in the form of matching contributions and/or an annual discretionary contribution fixed by appropriate action of the Company. There were no Company contributions for the 2005 and 2004 plan years. Participant accounts -------------------- Each participant's account is credited with the participant's contribution and allocations of the Company's contribution (if any) and the Plan earnings, and charged with an allocation of administrative expenses. Allocations are based on participant account balances, as defined in the Plan documents. The benefit to which a participant is entitled is the participant's vested account balance. Vesting ------- Participants are immediately vested in their contributions plus actual earnings thereon. Vesting in the Company's matching and discretionary contribution portion of their accounts plus actual earnings thereon is based on years of continuous service. A participant is 100% vested in the Company contributions after five years of credited service. There is no partial vesting. Page 5 ------ Participant loans ----------------- Participants may borrow from their account a minimum of $1,000 with a maximum equal to the lesser of $50,000 or 50% of their vested account balance. Loan transfers are treated as a transfer to (from) the investment fund from (to) the Loan Fund. Loan terms range from one to five years or a reasonable period of time determined when the loan is made for the purchase of a primary residence. The loans are collateralized by the balance in the participant's account and bear interest at a rate commensurate with local prevailing rates as determined by the Plan Administrator. Principal and interest are paid ratably through bi-weekly payroll deductions. Payment of benefits ------------------- On termination of service due to death, disability, or retirement, a participant 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 monthly, quarterly, semi-annual or annual installments over a period not to exceed the life of the participant or the life of a designated beneficiary. Administration -------------- The Plan is administered by the Company. The Company has selected MFS to be the Recordkeeper of the Plan and Reliance Trust Company as the Trustee. Administrative expenses are paid by the participants and the Company. An asset-based fee is paid by the participants on an annual basis. This amount is deducted from participant accounts and placed in a holding account, which is merged with the MFS Fixed Fund. Any remaining administrative expenses in excess of the amounts which are set aside by the Plan are paid by the Company. 2. Summary of Accounting Policies ------------------------------ Basis of Accounting: The financial statements of the Plan are prepared under the accrual method of accounting. Investments and Related Transactions: The Plan's investments are reflected at current market value as measured by quoted market prices in an active market or as determined in good faith by the Trustee. Shares of mutual funds are valued at the net asset value of shares held by the Plan at year-end. Net appreciation/(depreciation) in fair value of investments includes both realized gains and losses and unrealized appreciation/(depreciation). Interest and dividend income is recognized as earned. Investment transactions are accounting for on the trade date. Participant loans are valued at cost, which approximates fair value. Page 6 ------ Payment of Benefits: Benefits are recorded when paid. Use of Estimates: The preparation of the Plan's financial statements in conformity with generally accepted accounting principles requires the Plan Administrator to make estimates and assumptions that affect the reported amounts of net assets and disclosures of contingent net assets at the date of the financial statements and the reported amounts of changes in net assets during the reporting period. Actual results could differ from those estimates. Reclassifications: Certain 2004 amounts have been reclassified to conform to the 2005 presentation. 3. Plan Termination ---------------- Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100 percent vested in their accounts. 4. Tax Status ---------- The Plan Administrator has not applied to the Internal Revenue Service for a determination letter for the Plan. The Plan was based upon a prototype plan designed by MFS Retirement Services, Inc. and received a favorable determination letter dated April 23, 2002. The Plan has been amended since receiving the determination letter. However, the Plan Administrator and the Plan's legal counsel believe that the Plan is currently designed and being operated in compliance with the applicable requirements of the Internal Revenue Code. Therefore, no provision for income taxes has been included in the Plan's financial statements. Page 7 ------ 5.
