INDEPENDENT AUDITORS' REPORT


Applied Industrial Technologies, Inc. Supplemental Defined Contribution Plan

We have audited the accompanying statements of net assets available for benefits
of the Applied Industrial Technologies, Inc. Supplemental Defined Contribution
Plan (the "Plan") as of December 31, 2003 and 2002, and the related statements
of changes in net assets available for benefits for each of the three years in
the period ended December 31, 2003. 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,
2003 and 2002, and the changes in net assets available for benefits for each of
the three years in the period ended December 31, 2003 in conformity with
accounting principles generally accepted in the United States of America.

APPLIED INDUSTRIAL TECHNOLOGIES, INC.
SUPPLEMENTAL DEFINED CONTRIBUTION PLAN

NOTES TO FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 2003, 2002 AND 2001
------------------------------------------------------------------------------

1.       DESCRIPTION OF THE PLAN

         The following description of the Applied Industrial Technologies, Inc.
         Supplemental Defined Contribution Plan (the "Plan") is provided for
         general information purposes only. Participants and users of the
         financial statements should refer to the Plan document for more
         complete information.

         GENERAL - The Plan was established by Applied Industrial Technologies,
         Inc. and its subsidiaries (the "Company") effective January 1, 1996,
         for the benefit of a select group of management or highly compensated
         employees. This is a non-qualified plan and is subject to the claims of
         creditors in the case of bankruptcy of Applied Industrial Technologies,
         Inc.

         ADMINISTRATION - The Plan is administered by the Company. The Company's
         powers and duties relate to making participant and employer
         contributions to the Plan's trust, establishing investment objectives,
         authorizing disbursements from the trust, and resolving any questions
         of Plan interpretation.

         The assets of the Plan are administered by American Express Trust
         Company acting as Trustee. The Trustee is responsible for the custody
         of assets.

         Effective March 1, 2003, American Express Trust Company and American
         Express Retirement Services, is the new trustee and record keeper,
         respectively, for the Applied Industrial Technologies, Inc.
         Supplemental Defined Contribution Plan. The transfer of the assets from
         Key Trust Co. of Ohio, N.A. to American Express Trust Company took
         place on March 3, 2003. There was a "blackout period" from March 3,
         2003 to April 1, 2003 during which time participants were unable to
         exercise their rights related to the Plan.

         PARTICIPANT ACCOUNTS - Each participant's account is credited with that
         participant's contribution and allocations of 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 amount that can be
         provided from the participant's vested account.

         PARTICIPATION AND CONTRIBUTIONS - Participation in the Plan is limited
         to select management or highly compensated employees of the Company and
         whose contributions under the Applied Industrial Technologies, Inc.
         Retirement Savings Plan (the "Retirement Savings Plan") are limited.

         There are no limits to the amount they can contribute. Participants may
         elect to transfer excess contributions from the Retirement Savings
         Plan. The company makes Supplemental Matching Contributions equal to
         the amount that matching contributions under the Retirement Savings
         Plan are limited each year due to Sections 401(k) and 401(m) of the
         Internal Revenue Code.

                                       4

         Supplemental Matching Contributions are segregated in the Matching
         Contributions Account and are invested in the Company Stock Fund.
         Non-participant directed investments included in the Company Stock Fund
         were $ 33,073 and $ 26,790 at December 31, 2003 and 2002, respectively.
         During the years ended December 31, 2003, 2002 and 2001, there were no
         Supplemental Matching Contributions made to the plan.


         Contributions are excluded from participants' taxable income until such
         amounts are received by them as a distribution from the Plan.

         INVESTMENT OF CONTRIBUTIONS - Participants elect investment of their
         contributions in 1% increments in the American Fundamental Investors
         Fund, EuroPacific Growth Fund, Pimco Total Return Fund, AXP S&P 500
         Index Fund, AXP Cash Management Fund, Calamos Growth Fund, Harbor
         Capital Appreciation, Vanguard Growth Index Fund, Wilshire Large
         Company Growth Portfolio, Alliance Growth and Income Fund, T Rowe Price
         Mid-Cap Growth Fund, Vanguard Asset Allocation Fund, Franklin Small-Cap
         Growth Fund, Royce Total Return Fund, or the Lord Abbett Mid-Cap Value
         Fund. Participants may change their investment elections as to future
         contributions and may also elect to reallocate a portion or all of
         their account balances among the investment funds in increments of 1%
         of the total amount to be reallocated. All such elections are filed
         with the Trustee and become effective daily.

         The value of the funds and the interest of individual participants
         under each fund are calculated daily (daily valuation).

         VESTING AND DISTRIBUTIONS - Each participant is immediately and fully
         vested in all participant contributions and earnings thereon.
         Participants vest in Supplemental Matching Contributions at a rate of
         25% for each year of eligible service, becoming completely vested after
         four years, or at death, termination of employment due to permanent and
         total disability, or normal or early retirement as defined in the Plan.

         Upon termination of service, participants may receive lump sum
         distributions of their vested account balances no later than 60 days
         after the end of the Plan year in which they terminate employment with
         the Company. Distributions upon retirement may be received as a lump
         sum or as installments in accordance with the participant's election.
         Participants may also apply for hardship withdrawals from their
         Supplemental Salary Savings Contributions, subject to adherence to
         Internal Revenue Service regulations and approval by the Company.

         Forfeitures of non-vested amounts are applied to reduce future
         Supplemental Matching Contributions. There were no forfeitures in 2003,
         2002 or 2001.

         PLAN TERMINATION - The Plan was adopted with the expectation that it
         will continue indefinitely. The Company may, however, terminate the
         Plan at any time and may amend the Plan from time to time. In the event
         of termination of the Plan, all participants will immediately become
         fully vested in the value of all Supplemental Matching Employer
         Contributions made on their behalf.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         BASIS OF ACCOUNTING - The accompanying financial statements have been
         prepared on the accrual basis of accounting.

                                       5


         USE OF ESTIMATES - The preparation of the financial statements in
         conformity with accounting principles generally accepted in the United
         States of America 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.

         VALUATION OF INVESTMENTS - Investments are accounted for at cost on the
         trade-date and are reported in the statement of net assets available
         for benefits at fair value. The investment in Company common stock is
         valued using the year-end closing price listed by the New York Stock
         Exchange. Investment funds are stated at fair values using year-end
         closing price for each of the funds or quoted market prices.

         RISK AND UNCERTAINTIES - In general, investment securities are exposed
         to various risks, such as interest rate, credit and overall market
         volatility risks. Due to the level of risk associated with certain
         investment securities, it is reasonably possible that changes in the
         values of investment securities could occur in the near term, and such
         changes could materially affect the amounts reported in the statements
         of net assets available for benefits and statement of changes in net
         assets available for benefits.

         BENEFITS PAYABLE - Distributions to participants are recorded by the
         Plan when payments are made.

         ADMINISTRATIVE EXPENSES - Administrative expenses of the Plan are paid
         by the Plan or the Company, as determined by the Company.

         INCOME TAXES - The Plan is not qualified under Section 401(a) of the
         Internal Revenue Code. Applied Industrial Technologies, Inc. is subject
         to federal income taxes arising from taxable income of the Plan.
         Accordingly, no provision for federal income taxes is included in the
         financial statements of the Plan.

3.       INVESTMENTS

         The Plan provides that, in accordance with the investment objectives
         established by the Company, the Trustee of the Plan shall hold, invest,
         reinvest, manage and administer all assets of the Plan as a trust fund
         for the exclusive benefit of participants and their beneficiaries.

         Plan investments exceeding 5% of net assets available for benefits as
         of December 31, 2003 and 2002, respectively, were as follows:
