                         Report of Independent Auditors

To the Plan Committee of
Cardinal Health Profit Sharing, Retirement and Savings Plan
For Employees of Puerto Rico

We have audited the accompanying statements of net assets available for benefits
of Cardinal Health Profit Sharing, Retirement & Savings Plan for Employees of
Puerto Rico as of December 31, 2002 and June 30, 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 audits.

We conducted our audits 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 audits provide 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 June 30, 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 audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The 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 audits 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.

           Cardinal Health Profit Sharing, Retirement and Savings Plan
                          for Employees of Puerto Rico

                          Notes to Financial Statements

                                December 31, 2002


1.        DESCRIPTION OF PLAN

GENERAL

The Cardinal Health Profit Sharing, Retirement and Savings Plan for Employees of
Puerto Rico (the Plan) is a defined contribution plan covering substantially all
employees of Cardinal Health, Inc. (the Company) residing in Puerto Rico and not
covered by a collective bargaining agreement who have completed one month of
service, as defined. 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.

Effective January 1, 2001, the Company 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's investments are not included in the
Master Trust.

Effective June 30, 2002, the Plan was amended to change the Plan year to a
calendar year, with a short Plan year for the six month period of July 1, 2002
to December 31, 2002.

CONTRIBUTIONS

Participants may contribute 1% to 10% 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. 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
primary residence. The loans are secured by the remaining vested balance in the
participant's account and bear interest at a rate commensurate with local
prevailing rates as determined monthly by the Plan Administrator. 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 and June 30, 2002 are as follows:

           Cardinal Health Profit Sharing, Retirement and Savings Plan
                          for Employees of Puerto Rico

                    Notes to Financial Statements (continued)

5.       INCOME TAX STATUS

The Plan has received a determination letter from the Puerto Rican Department of
Treasury dated July 10, 2000, stating that the Plan is qualified under Section
1165(a) of the Puerto Rico Internal Revenue Code of 1994 (the "Code") and,
therefore, the related trust is exempt from taxation. Once qualified, the Plan
is required to operate in conformity with the Code to maintain its
qualification. The Plan Administrator believes 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.

6.       RISKS AND UNCERTAINTIES

The Plan has a significant participant-directed investment in Cardinal Health,
Inc. common stock, which is exposed to various risks, such as interest rate,
credit, and overall market volatility risk. Due to the level of risk involved
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 statements of net
assets available for benefits and changes in net assets available for benefits.

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 provisions of ERISA. In the event of Plan termination,
participants will become 100 percent vested in their accounts.

8.       RELATED PARTY TRANSACTIONS

The Plan held $651,672 and $375,343 of Cardinal Health, Inc. common stock as of
December 31, 2002 and June 30, 2002, respectively.
