                      CARDINAL HEALTH PROVIDES CHRONOLOGY
                   AND SUPPLEMENTAL INFORMATION ON SEC MATTER

DUBLIN, OHIO, MAY 16, 2004--In connection with the press release issued and Form
10-Q filed on May 14, 2004, Cardinal Health, Inc. (NYSE: CAH) provided the
following chronology and supplemental information in connection with the
previously announced SEC investigation and audit committee review of certain
accounting matters:

- - On October 7, 2003, the Company received a request from the SEC, in connection
  with an informal inquiry, for historical financial and related information
  including but not limited to the accounting treatment of the recovery from
  vitamin manufacturers. The SEC's request sought a variety of documentation,
  including the Company's accounting records for fiscal 2001 through fiscal
  2003, as well as notes, memoranda, presentations, e-mail and other
  correspondence, budgets, forecasts and estimates.

- - Since October 2003, the Company has been collecting and providing to the SEC
  documents responsive to the October request. Due to the scope of the October
  request and the breadth of the Company's operations, the Company is
  cooperating with the SEC to provide documents to the SEC on a rolling basis,
  and that process is ongoing.

- - In April 2004, the Company's audit committee determined to undertake an
  internal review and retained independent counsel. This review:

  - was prompted by documents contained in the production to the SEC that raised
    issues as to certain accounting matters, including but not limited to the
    establishment and adjustment of certain reserves and their impact on
    quarterly earnings, and is not limited to the accounting treatment of the
    recovery from vitamin manufacturers; and

  - is ongoing and has not reached any conclusions.

- - As disclosed in the Company's Form 10-Q, if the audit committee review
  determines that any changes are required to the Company's disclosure controls
  and procedures or internal controls, the Company will make any necessary
  modifications.

- - On May 6, 2004, the Company was notified that the pending SEC inquiry had been
  converted to a formal investigation. The SEC investigation is not limited to
  the accounting treatment of the recovery from vitamin manufacturers.

- - The Company intends to continue to respond to the SEC's ongoing investigation
  and provide all information required by the SEC.
