(Attach extra Sheets if Needed)





     As previously reported, in October 2003, the Securities and Exchange
Commission (the "SEC") initiated an informal inquiry regarding Cardinal Health,
Inc. (the "Company"). The SEC's request sought historical financial and related
information including but not limited to the accounting treatment of certain
recoveries 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. In connection with the
SEC's informal inquiry, the Audit Committee of the Board of Directors of the
Company commenced its own internal review in April 2004, assisted by independent
counsel, which review has been ongoing. On May 6, 2004, the Company was notified
that the SEC had converted the informal inquiry into a formal investigation. On
June 21, 2004, as part of the SEC's formal investigation, the Company received
an additional SEC subpoena that included a request for the production of
documents relating to revenue classification, and the methods used for such
classification, in the Company's Pharmaceutical Distribution business as either
"Operating Revenues" or "Bulk Deliveries to Customer Warehouses and Other." In
addition, the Company learned that the U.S. Attorney for the Southern District
of New York had also commenced an inquiry with respect to the Company that the
Company understands relates to the revenue classification issue. The Company
continues to respond to the SEC investigation and the Audit Committee internal
review and provide all required information.

     The Company's inability to file the Form 10-K within the prescribed time
period is because the Audit Committee's internal review is ongoing, and the
Audit Committee and the Company need additional time to complete the work
necessary to be ready to file the Form 10-K.


PART IV -- OTHER INFORMATION

(2)  Have all other periodic reports  required under Section 13 or 15(d) of the Securities  Exchange Act of 1934 or
     Section 30 of the  Investment  Company Act of 1940 during the  preceding 12 months or for such shorter  period
     that the registrant was required to file such report(s) been filed?  If answer is no, identify report(s).
     Yes  /X/    No  / /

     -------------------------------------------------------------------------------------------------------------------------

(3)  Is it anticipated that any significant change in results of operations from the corresponding period for the
     last fiscal year will be reflected by the earnings statements to be included in the subject report or portion
     thereof?                                                                                  Yes  /X/    No  / /

     If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate,
     state the reasons why a reasonable estimate of the results cannot be made.

      For an explanation of certain anticipated changes in results of operations, reference is made to the Company's
Current Report on Form 8-K, including the press release attached as Exhibit 99.01 thereto, filed with the SEC on
