INDEPENDENT AUDITORS' REPORT


Trustees
Butler International, Inc.
401(k) Plan
Montvale, New Jersey


We have audited the accompanying statements of net assets available for benefits
of the Butler International, Inc. 401(k) Plan ("the Plan") as of December 31,
2000 and 1999, and the related statement of changes in net assets available for
benefits for the year ended December 31, 2000.  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 auditing standards generally accepted
in the United States of America.  Those standards 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.  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, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of December 31,
2000 and 1999 and the changes in net assets available for benefits for the year
ended December 31, 2000 in conformity with accounting principles generally
accepted in the United States of America.

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
for investment purposes as of December 31, 2000 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 schedule is the responsibility of
the Plan's management.  Such schedule has been subjected to the auditing
procedures applied in our audit of the basic 2000 financial statements and, in
our opinion, is fairly stated in all material respects when considered in
relation to the basic 2000 financial statements taken as a whole.

BUTLER INTERNATIONAL, INC. 401(k) PLAN
NOTES TO FINANCIAL STATEMENTS

1. PLAN DESCRIPTION

  The following description of the Butler International, Inc. 401(k) Plan (the
  "Plan") provides only general information.  Participants should refer to the
  plan document for a more detailed description.

  General:

  In November 1989, Butler Service Group, Inc. (the "Company") established the
  Plan, which was adopted by its wholly owned subsidiaries.  The Plan is a
  continuation of the Butler Service Group, Inc. Investment Savings Plan and is
  designed to provide an incentive for employees of the Company to save
  regularly through payroll deductions and possible matching contributions by
  the Company.  The Plan is a defined contribution plan covering all employees
  of the Company.  It is subject to the provisions of the Employee Retirement
  Income Security Act ("ERISA").

  The Employee Benefits Administrative Committee comprising up to three persons
  appointed by the Company's Board of Directors administers the Plan.  The trust
  department of an independent third-party bank is the Plan's Trustee.

  Contributions:

  Generally, participants may contribute from 1% to 20%, in whole percentages,
  of eligible compensation to the Plan on a pretax basis through automatic
  payroll deductions ("elective deferral contributions").  Participants may also
  contribute amounts representing distributions from other qualified defined
  benefit or defined contribution plans.  Participants direct the investments of
  their contributions into various investment options offered by the Plan.  The
  Plan currently offers 15 investment options, which include a bank collective
  fund, various mutual funds and the Butler Stock Fund.  Total participant
  contributions in any calendar year are limited to the applicable limit under
  Internal Revenue Code Section 402(g).  Such limit is $10,500 and $10,000 for
  calendar years 2000 and 1999, respectively.  The Plan also provides that
  certain limitations may be imposed on participant's contributions in order to
  comply with statutory requirements.  Other liabilities include refunds of
  excess contributions to highly compensated employees.  Participants may
  request changes to their elective deferral contribution rate or discontinue
  their contributions through the Plan's voice response system.  The changes or
  discontinuance will be effective as soon as it is administratively feasible.

    The Company may make matching contributions or other additional
  discretionary contributions to the Plan in amounts determined by the Employee
  Benefits Administrative Committee.  Any such contributions are allocated to
  the participants' accounts as provided by the Plan and invested directly in
  the Butler Stock Fund or, as specified under a customer contract, allocated in
  proportion to the elective deferral contributions.  In 2000 and 1999, the
  Company made matching contributions of approximately $596,000 and  $544,000,
  respectively.  In 2000 and 1999, the Company also made contributions of
  approximately $1,090,000 and $1,129,000, respectively, to the Plan in
  accordance with a customer contract, which was funded by the customer.

  Participant Accounts:

  Each participant's account is credited with the participant's contributions
  and allocations of (a) the Company's contribution and (b) Plan earnings, and
  charged with an allocation of 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.

  Participant Loans:

  Participants may borrow from their fund accounts a minimum of $1,000 up to a
  maximum equal to the lesser of $50,000 or 50 percent of the vested portion of
  their account balance.  The loans are secured by the balance in the
  participant's account and bear interest at a rate of Prime plus 1 percent.
  Principal and interest is paid ratably through payroll deductions.  Loans must
  be repaid within an agreed period but no more than five years.  However, if
  the loan is made for the purchase or construction of the participant's
  principal place of residence, the repayment period may be longer than five
  years.  Only one loan will be granted at a time and must be repaid in full
  before another loan can be requested.

                                                                               6

  according to the following schedule:


                                                                 Percentage of

  A participant is also 100% vested if termination of employment is due to
  retirement after age 65, total disability or death.

  Forfeited Accounts:

  When certain terminations of participation in the Plan occur, the nonvested
  portion of the participant's account, as defined by the plan, represents a
  forfeiture. Forfeitures are utilized to reduce the Company's future
  contributions.  At December 31, 2000, forfeited nonvested accounts totaled
  approximately $4,000.  Also, in 2000, employer contributions were reduced by
  $15,000 from forfeited nonvested accounts.

  Payment of Benefits:

  On termination of services, a participant may elect to: (1) receive a lump-sum
  payment; (2) roll over funds to another qualified plan or an Individual
  Retirement Plan; or (3) defer receipt of funds that exceed $5,000 until April
  1 following the later of the calendar year the participant reaches age 70 1/2
  or the calendar year of participant's retirement.  Participants may withdraw
  funds while employed only from accounts in which they are fully vested after
  attaining age 59 1/2.  Prior to attaining age 59 1/2 a withdrawal may be made
  for financial hardship.  Only one withdrawal may be requested during any Plan
  year for reasons other than financial hardship.  The minimum amount available
  for a withdrawal is $500.  If the participant has an outstanding loan, the
  amount of funds available for withdrawal may be limited.  A participant will
  have a 100% vested interest in all accounts upon retirement at or after age
  65, in the event of a permanent disability or in the event of death prior to
  termination of employment.  Upon termination of employment, the value of the
  vested accounts will be paid in a lump sum.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  The accompanying financial statements are prepared on the accrual basis of
  accounting and are presented in accordance with the financial reporting
  requirements of ERISA.

  Use of Estimates

  The preparation of financial statements in conformity with generally accepted
  accounting principles requires management to make estimates and assumptions
  that affect the reported amounts of assets and liabilities and changes
  therein, and disclosure of contingent assets and liabilities.  Actual results
  could differ from those estimates.

                                                                               7

  Investment Valuation and Income Recognition

  The Plan's investments are stated at fair value.  Quoted market prices are
  used to value investments except for its collective trust fund.  Investments
  in collective trust fund are stated at estimated fair values, which have been
  determined based on the unit values of the funds.  The bank sponsoring the
  collective trust fund determines the unit value by dividing the fund's net
  assets at fair value by its units outstanding at the valuation dates.  Shares
  of mutual funds are valued at the net asset value of shares held by the Plan
  at year-end.  Participant loans are valued at cost, which approximates fair
  value.

  Purchases and sales of securities are recorded on a trade-date basis. Interest
  income is recorded on the accrual basis.  Dividends are recorded on the ex-
  dividend date.

  Net Appreciation (Depreciation) in Fair Value of Investments

  Net realized and unrealized appreciation (depreciation) is recorded in the
  accompanying financial statements as net appreciation (depreciation) in fair
  value of investments.

  Payment of Benefits

  Benefits are recorded when paid.

3.  RELATED-PARTY TRANSACTIONS

  Certain Plan investments are shares of mutual funds managed by Prudential Bank
  and Trust Company ("Prudential").  Prudential is the trustee as defined by the
  Plan and, therefore, these transactions qualify as party-in-interest
  transactions.  For the year ended December 31, 2000, fees paid by the Plan for
  administrative services amounted to $110,000, which includes application and
  processing fees for participant loans.  Officers and employees of the Company
  perform certain administrative functions for the Plan.  No such officer or
  employee receives compensation from the Plan.

6. TAX STATUS

  The Internal Revenue Service has determined and informed the Company by a
  letter dated April 22, 1996, that the Plan and related trust are designed in
  accordance with applicable sections of the Internal Revenue Code ("IRC").  The
  Plan has been amended since receiving the determination letter.  However, the
  Plan administrator believes that the Plan is currently designed and being
  operated in compliance with the applicable requirements of the IRC.
  Therefore, there is no provision for income taxes in the financial statements.

7.  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 provision of ERISA.  In the event the Plan is
  terminated, all participants will be 100% vested in all their accounts and
  benefits will be payable strictly under the terms of the Plan. The Pension
  Benefit Guaranty Corporation does not insure benefits under defined
  contribution plans of the 401(k) type.

                                                                               9
