Report of Independent Registered Public Accounting Firm
-------------------------------------------------------

To the Participants and Administrator of the
Ecology and Environment, Inc. 401(k) Plan

In our opinion, the accompanying statements of net assets available for
benefits and the related statements of changes in net assets available for
benefits present fairly, in all material respects, the net assets available
for benefits of the Ecology and Environment, Inc. 401(k) Plan (the "Plan")
at December 31, 2003 and 2002, 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.  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 of these statements in accordance
with auditing standards generally accepted in the United States of America,
which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit 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 audits provide a reasonable basis for our opinion.

Our audits were conducted 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 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.  The 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.

Ecology and Environment, Inc.
401(k) Plan
Notes to Financial Statements
December 31, 2003 and 2002
----------------------------------------------------------------------------

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.  On August 1, 2002, the Plan changed the Recordkeeper
from Dreyfus Retirement Services (Dreyfus) to MFS Retirement Services, Inc.
(MFS) and changed the Trustee and Account Owner from Dreyfus to Reliance
Trust Company.  In connection with these changes, a new plan agreement was
adopted (new plan agreement) on August 1, 2002.

     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).  Under the old plan agreement, eligibility was defined as an
employee who has completed a minimum of 1,000 hours of service and was age
twenty-one or older.  Under the new plan agreement, 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 (ERISA).

     Contributions
     -------------

     Prior to August 1, 2002, participants could elect to make voluntary
contributions up to 15% of their annual compensation subject to the maximum
amount allowable by the Internal Revenue code sections 401(k), 402(g), 404
and 415.  Beginning August 1, 2002, participants may elect to make voluntary
contributions subject only to the limitations of the Internal Revenue Code. 
The Internal Revenue Services' maximum deferral contribution amount was
$12,000 for 2003 and $11,000 for 2002.  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
investment options in at least 10 percent increments in each option selected.

     Under both the old and new plan agreements, 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 2003 and 2002 plan years.

     Participant accounts
     --------------------

     Each participant's account is credited with the participant's
contributions and allocations of the Company's contributions (if any) and
the Plan earnings, and charged with an allocation of the portion of
administrative expenses borne by the Plan.  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
     -----------------

     Under both the old and new plan agreements, 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.  Loans are treated as a
transfer to (from) the respective investment fund from (to) the Loan Fund.  
Loan terms range from one to five years or from five to twenty years 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 utilized Dreyfus
as the Recordkeeper and Trustee of the Plan through July 31, 2002. 
Beginning August 1, 2002, the Company selected MFS to be the Recordkeeper of
the Plan and Reliance Trust Company as the Trustee and Account Owner.

     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.  Investments in Ecology and Environment, Inc. common stock
are valued at the last reported sales price on the last business day of the
month.  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
accounting principals generally accepted in the United States 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 change in
net assets during the reporting period.  Actual results could differ from
those estimates.

3.   Plan Termination
     ----------------

     Although it has not expressed any intent to do so, the Company has the
right under the Plan to discontinue the Plan 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.  From the commencement of the Plan
through July 31, 2002, the Plan was based upon a prototype plan designed by
the Dreyfus Corporation and received a favorable determination letter dated
September 1, 1994.  Beginning August 1, 2002, the Plan is based upon a
prototype plan designed by MFS Retirement Services Inc. which 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.
