INDEPENDENT AUDITORS' REPORT

Savings and Investment Plan Committee
Analysts International Corporation
Minneapolis, Minnesota

We have audited the accompanying statements of net assets available for plan
benefits of Analysts International Corporation Savings and Investment Plan (the
Plan) as of June 30, 2000 and 1999 and the related statements of changes in net
assets available for plan benefits for the years then ended. 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 plan benefits as of June 30, 2000 and
1999 and the changes in net assets available for plan benefits for the years
then ended 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 information by fund for
the years ended June 30, 2000 and 1999, the supplemental schedules of Assets
Held for Investment Purposes as of June 30, 2000 and Reportable Transactions for
the year ended June 30, 2000 are presented for purposes of additional analysis
of the basic financial statements and for complying with the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974 and are not a required part of the basic
financial statements. This supplemental information is the responsibility of the
Plan's management. The supplemental information and schedules have been
subjected to the auditing procedures applied in the audit of the basic financial
statements and, in our opinion, are fairly stated in all material respects in
relation to the basic financial statements taken as a whole.

                       ANALYSTS INTERNATIONAL CORPORATION
                          SAVINGS AND INVESTMENT PLAN

                          NOTES TO FINANCIAL STATEMENTS

                       YEARS ENDED JUNE 30, 2000 AND 1999

A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Investments are stated at market value using quoted market values. Promissory
notes from participants are stated at the outstanding principal balance.

The financial statements have been prepared on the accrual basis of accounting.
All security transactions are recorded on their trade date.

Participants have control over the allocation of their account balances among
each of the eleven non-AIC Common Stock Funds. However, because Analysts
International Corporation (AIC) designates the investment option for the
employer matching contributions in the AIC Common Stock Fund, participants do
not have complete control of their assets invested in this fund.

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of financial
statements and the reported amounts of additions and deductions during the
reporting period. Actual results could differ from those estimates.


B.  THE PLAN:

The Plan was established January 1, 1985 under Section 401(k) of the Internal
Revenue Code for the purpose of providing retirement and other benefits to
eligible participants. An employee of AIC becomes eligible for the Plan upon
commencement of active service.

The Plan is funded primarily by employee contributions. Eligible employees may
contribute up to 15% of their gross annual wages for pre-tax saving
contributions. In addition, the Plan allows rollover contributions from certain
qualified retirement plans.

Plan participants may choose to have their share of the Plan funds invested in
one or more of eleven investment funds offered by the Putnam, Vanguard and Janus
Companies and/or the AiC Common Stock Fund. The eleven funds include the Putnam
Money Market Fund, the Putnam U.S. Government Income Trust, the Putnam High
Yield Trust, the Putnam Fund for Growth and Income, the Putnam Voyager Fund, the
Putnam Global Growth Fund, the Putnam OTC Emerging Growth Fund, the Putnam
International Growth Fund, the Vanguard 500 Index Fund,


                                       5
<PAGE>

the Janus Mercury Fund and the Janus Growth and Income Fund. Effective April 3,
2000 the Plan was amended adding the Vanguard 500 Index Fund, the Janus Mercury
Fund and the Janus Growth and Income Fund. A participant's account (consisting
of employee contributions and investment income) is fully vested.

Participant loans are made in compliance with federal regulations in effect at
the time of the loan. Participant loans outstanding, included in investments,
amounted to $1,024,182 at June 30, 2000 and $1,081,413 at June 30, 1999.

The Plan provides for employer matching contributions where the employer matches
18% of the employee's pre-tax saving contributions, provided the employee has
been employed by the employer for one year or more and is not a highly
compensated employee as defined by federal tax laws. The employer matching
contributions are invested in the AIC Common Stock Fund.

A participant's interest in the employer matching contribution vests at the
rate of 20% per year after three years of service with 100% vesting after
seven years. Any nonvested portion of employer matching contributions to the
accounts of participants who withdraw from the Plan are forfeited in
compliance with federal regulations and used by the employer to reduce future
matching contributions.

Although the Company has not expressed an intent to discontinue the Plan, it may
do so at any time, subject to provisions set forth in the Employee Retirement
Income Security Act of 1974. If the Plan is terminated, no further contributions
will be made. The trustee will continue to hold the funds and make distributions
as if the Plan had not terminated.

C. TRUSTEE AND ADMINISTRATION OF THE PLAN:

Putnam Fiduciary Trust Company has been designated as trustee. Investments of
the Plan are held by Putnam Investor Services, Inc. on behalf of the trustee.

The Company has established a Savings and Investment Plan Committee for the
general administration of the Plan.

The Company pays the trustee fees on behalf of the Plan.

D.  INTERNAL REVENUE SERVICE STATUS:

The IRS has issued determinations that the Plan, as originally adopted January
1, 1985, and as amended through January 17, 1994, is a qualified plan for tax
purposes under Sections 401(a) and 401(k) of the Internal Revenue Code, and that
the trust established in connection therewith is exempt from income tax under
Section 501(a) of the Code. The Company believes the Plan as presently
constituted and operated continues to meet the requirements of Sections 401(a)
and 401(k) of the Code and that the related trust is exempt from income tax
under Section 501(a) of the Code.
