                         Report of Independent Auditors

To the Plan Committee of
Cardinal Health Profit Sharing, Retirement and Savings Plan for PRN Employees


We have audited the accompanying statement of net assets available for benefits
of Cardinal Health Profit Sharing, Retirement and Savings Plan for PRN Employees
as of December 31, 2002, and the related statement of changes in net assets
available for benefits for the six month period 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.

We conducted our audit in accordance with auditing standards generally accepted
in the United States. 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 financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December 31, 2002, and the changes in its net assets available for benefits for
the six month period ended December 31, 2002, in conformity with accounting
principles generally accepted in the United States.

Our audit was performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
(held at end of year) is presented for purposes of additional analysis and is
not a required part of the 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 and has
been subjected to the auditing procedures applied in our audit of the financial
statements and, in our opinion, is fairly stated in all material respects in
relation to the financial statements taken as a whole.

                             Plan for PRN Employees

                          Notes to Financial Statements

                                December 31, 2002

1.         DESCRIPTION OF PLAN

GENERAL

The Cardinal Health Profit Sharing, Retirement and Savings Plan for PRN
Employees, established July 1, 2002, is a defined contribution plan covering all
employees classified as PRN who have completed one year of service, as defined.
The Plan has a calendar year end; therefore, the statement of changes in the net
assets available for benefits is for the six month period since inception of the
Plan. This description of the Plan provides only general information.
Participants should refer to the Plan Document for a more complete description
of the Plan's provisions.

The Plan is administered by the Plan committee. The Plan trustee, record keeper
and asset custodian is Putnam Fiduciary Trust Company (Putnam). Administrative
expenses may be paid by the Company or the Plan, excluding loan fees, which are
paid by the borrowing participant.

As record keeper and asset custodian of the Plan, Putnam maintains certain
accounting and other records of the Plan transactions and assets. Therefore, the
Plan and the Plan committee rely on Putnam to provide the appropriate
information for purposes of preparation of the financial statements for the
Plan. Although certain procedures are designed to obtain reasonable assurance
about whether the information provided by Putnam is complete and free of
material misstatement, the Plan and Plan committee's ability to verify the
information is somewhat limited. For purposes of disclosures made in these
financial statements and related certifications, the Plan and Plan committee
have no reason to believe that the information provided by Putnam does not
fairly present, in all material respects, the financial condition and results of
operations of the Plan.

Cardinal Health, Inc. established the Master Trust for Retirement Plans of
Cardinal Health (the Master Trust) for the Plan and certain other Company plans.
Certain of the Plan investments are not included in the Master Trust.

CONTRIBUTIONS

Participants may contribute 1% to 50% of their compensation, as defined, to the
Plan. Participants direct the investment of their contributions into various
investment options offered by the Plan. The Company may contribute discretionary
matching and profit sharing contributions to the Plan. The Company's
discretionary matching and profit sharing contributions are invested as directed
by participants. Contributions are subject to certain limitations.

                    Notes to Financial Statements (continued)

1.         DESCRIPTION OF PLAN (CONTINUED)

FORFEITURES

Non-vested account balances are generally forfeited either upon full
distribution or completion of five consecutive one-year breaks in service, as
defined. Such forfeited amounts are used to reduce future Company contributions
to the Plan.

PARTICIPANT ACCOUNTS

Each participant's account is credited with the participant's elective
contributions, allocations of the Company's contributions, Plan earnings and any
rollover contributions made by the participant. A participant is entitled to the
benefit provided from the participant's vested account balance. All amounts in
participant accounts are participant-directed.

VESTING

Participants are vested immediately in their elective contributions, plus actual
earnings thereon. Vesting in the Company's discretionary contribution portion of
their accounts is based on years of continuous service. A participant is 100
percent vested after three years of vesting service.

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 their vested account
balance. Loan terms range from 1-5 years or up to 15 years for the purchase of a
principal residence. The loans are secured by the remaining vested balance in
the participant's account and bear interest at a rate comparable to the rates
being charged by commercial lending institutions for similar loans at the time
the loan is approved. Principal and interest are repaid ratably through regular
payroll deductions.

PAYMENT OF BENEFITS

Upon termination of employment, death, retirement or disability, all
distributions will be made in the form of a lump-sum payment. In addition, the
Plan includes a provision for participants to make withdrawals from their
account under certain "hardship" circumstances.

2.         SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

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

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

USE OF ESTIMATES

The preparation of financial statements requires management to make estimates
and assumptions that affect the financial statements and accompanying notes.
Actual results could differ from those estimates.

INVESTMENT VALUATION AND INCOME RECOGNITION

The investments of the Plan are stated at fair market value as determined by the
asset custodian using quoted market prices of underlying investments. Investment
securities, in general, are exposed to various risks, such as interest rate,
credit, and overall market volatility risk. Participant loans are valued at
cost, which approximates fair market value.

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

3.       INVESTMENTS

The fair market values of individual assets that represent 5% or more of the
Plan's assets as of December 31, 2002 are as follows:

5.       INCOME TAX STATUS

The Plan has not received a determination letter from the Internal Revenue
Service stating that the Plan is qualified under Section 401(a) of the Internal
Revenue Code (the "Code"). Once qualified, the Plan is required to operate in
conformity with the Code to maintain its qualification. The Plan Administrator
believes that the Plan is being operated in compliance with the applicable
requirements of the Code and, therefore, believes that the Plan is qualified and
the related trust is tax exempt.
