INDEPENDENT AUDITOR'S REPORT

To the Benefits Policy Committee and
  Participants of the Cummins Inc. and
  Affiliates Retirement and Savings Plan for ONAN
  Corporation Employees
Columbus, Indiana

We have audited the accompanying statement of net assets available for benefits of the Cummins Inc. and Affiliates Retirement and Savings Plan for ONAN Corporation Employees (the "Plan") as of December 31, 2002, and the related statement of changes in net assets available for benefits for the year ended December 31, 2002.  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 audit.  The financial statements of Cummins Inc. and Affiliates Retirement and Savings Plan for ONAN Corporation Employees as of December 31, 2001, were audited by other auditors whose report dated July 5, 2002, expressed an unqualified opinion on those statements.

We conducted our audit 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 audit provides a reasonable basis for our opinion.

In our opinion, the 2002 financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2002, and the changes in net assets available for benefits for the year ended December 31, 2002, in conformity with accounting principles generally accepted in the United States of America.

Matching Contributions

The Company matches participant contributions in amounts ranging from 100% of the first $250, 75% of the next $250, 50% of the next $1,000 and 25% of the next $1,000 of participant wages contributed to $1,188.  The matching contribution is made in the form of cash or company stock, based on the participant's employing company, as defined.  Prior to May 1, 2002, Company matching contributions in the form of Company stock could not be reinvested into other investment options until the participant is 55 years of age.  On May 1, 2002, the Company started removing restrictions on the reinvestment of Company stock received as a match.  At December 31, 2002, 80% of Company stock received as a match was available for diversification.  Subsequent to February 1, 2003, the entire amount of Company stock received as a match is available for diversification.

Participant Accounts

Each participant's account is credited with the participant's contributions, the Company's contributions and an allocation of Plan earnings.  Allocations of Plan earnings are made daily and are based upon the participant's weighted average account balance for the day, as described in the Plan document.

Vesting

Participants are fully vested in all employee and employer contributions and earnings thereon at all times.

Benefit Payments

Upon termination of employment or retirement, account balances are paid either as a lump-sum distribution or annual installments not to exceed the lesser of 15 years or the life expectancy of the participant and/or joint life expectancy of the participant and beneficiary, and commence no later than the participant reaching age 70-1/2.  The Plan also permits hardship withdrawals from participant pre-tax contributions and actual earnings thereon.  Participants may also withdraw their after-tax contributions.

Voting Rights

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting

The financial statements of the Plan have been prepared on the accrual basis of accounting.

Investments

The Plan's investment in the Master Trust is stated at fair value based on the fair value of the underlying investments of the Master Trust, determined primarily by quoted market prices, except for the fixed income fund.  The fixed income fund consists primarily of insurance contracts and bank investment contracts with various insurance companies and is stated at contract value as the investments are fully benefit-responsive.  The contract values represent contributions made under the contracts, plus earnings, less withdrawals and administrative expenses.  Withdrawals or transfers from the fund are valued at contract value.

Allocation of Master Trust Assets and Transactions

The investment income and expenses of the Master Trust are allocated to each plan based on the relationship of the Plan's investment balances to the total Master Trust investment balances.

Use of Estimates

The preparation of financial statements, in accordance 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, liabilities, and changes therein, and disclosure of contingent assets and liabilities.  Actual results could differ from those estimates.

Risks and Uncertainties

The Master Trust invests in various securities.  Investment securities, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility.  Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the financial statements.

Administrative Expenses

Substantially all costs of administering the Plan are paid by the Company.

      12.5%, respectively.  The following investments are held by the Master Trust as of December 31:

Interest

Dividends

        4,816,054

4.   TAX STATUS

The Plan received a favorable determination letter dated June 10, 1996 in which the Internal Revenue Service ("IRS") stated that the Plan, as then designed, was in compliance with the applicable requirements of the Internal Revenue Code (the "Code").  The Plan has been amended since receiving that determination letter.  The Plan submitted a request to the IRS for a new determination letter, but has not yet received a reply.  The Company and its counsel believe that the Plan is currently designed and being operated in compliance with the applicable requirements of the Code.  Therefore, no provision for income taxes has been included in the Plan's financial statements.

5.   RELATED PARTY TRANSACTIONS

Certain Master Trust investments are shares of mutual funds managed by The Vanguard Group, and shares of Cummins Inc.  The Vanguard Group is the trustee of the Master Trust and Cummins Inc. is the Plan Sponsor; therefore, transactions with these parties qualify as party-in-interest transactions.

6.   CONTINGENCY

The Plan is currently undergoing an audit by the Internal Revenue Service for plan years 1999 through 2001.  As this audit is not yet complete, the financial statements do not reflect any potential liability related to this audit.  In addition, the Company is not aware of any potential plan disqualification issues that have arisen during this audit.
