                      Thank you Mr. Fischbach you may now begin your conference.

Steve Fischbach:      Thank you good afternoon and welcome. I know
                      this is an unusual call for Cardinal but thanks for
                      joining us today, I know we have a big crowd. Speaking on
                      our call today will be Bob Walter, Chairman and CEO but
                      before we begin I would like to remind everyone that some
                      of the information discussed on today's call includes
                      forward-looking statements.





                      In addition, in connection with our proposed acquisition
                      of (Syncor) International; (Syncor) intends to mail a
                      proxy statement and prospectus to stockholders and
                      Cardinal Health, intends to file registration statement
                      related to that transaction. Information about the
                      transaction is available from Cardinal and (Syncor).

                      At this time I'll turn the call over to Bob Walter to
                      begin today's discussion.

Bob Walter:           Good afternoon. Well I guess we've proven that we
                      can organize a call on short notice. I think we have on
                      this call between two and three times the number of
                      interested investors that we have on any of our normal
                      calls.

                      Let me say up front there will not be any surprises,
                      continued good performance by Cardinal. We are in an
                      unusual time where the environment is full of suspicion
                      rather than trust. That pendulum is clearly swung. It will
                      swing back.

                      Last Thursday a corporation said we are not subject to
                      accounting investigation and strongly believe that its
                      accounting is appropriate. The Corporation founded in 1908
                      - $177 billion in revenues and we're the largest US
                      corporation that was General Motors.

                      So last Thursday was General Motors day for talking about
                      the quality of what they do. Today is our day and next
                      week some other outstanding company will respond. As I say
                      the pendulum will swing back more to trust rather than to
                      suspicion.

                      Investors need to have confidence in the future and
                      frankly if you can't trust the reporting of the past how
                      can you trust forecasts for the future. Let me deal with
                      the issue of the past, the present and the future.





                      In the past on August 3 of this year we will have 19 years
                      since our initial public offering. That's 19 years of
                      living to a consistently high level of operational,
                      ethical and financial performance in our dealings with
                      customers, associates and shareholders.

                      The 19 years of open communications of our expectations
                      for the future, we have 19 years of detailed reporting and
                      we now report in four segments with a lot of detail within
                      each one of those segments.

                      We have 19 years of meeting or exceeding our financial
                      expectations and 19 years of responsible conservative
                      accounting. We have 19 years of - without disagreements
                      with outside auditors, no unusual accounting - I would
                      remind everybody that 98% of our revenues are from cash
                      receipts.

                      We have demonstrated a conservative approach over a very
                      long period of time. Our earnings approximately equal our
                      cash flow which is a very good test. We will - our
                      earnings this year will be more than 85% of our - our cash
                      flow I'm sorry will be more than 85% of our earnings.

                      Our level of debt is low and it always has been; another
                      reflection of our conservatism. The top level management,
                      here I'm referring to myself, has been in place all of
                      these 19 years, so I take a great deal of pride in this
                      ethical high performance standard environment.

                      Let's deal with the present. We are under no investigation
                      by the SEC, DEA, FDA or any other regulatory body.
                      Recognizing that these regulatory bodies have on-going and
                      routine reviews, but they are normal and routine.






                      Our transition from Arthur Andersen to Ernst & Young is
                      normal and customary. It is smooth, it is timely, it has
                      no surprises, it's very straight forward and our yearend
                      audit will be completed and earnings released on schedule.

                      Cardinal has always received an unqualified clean audit
                      opinion. Cardinal has fully complied with all accounting
                      rules and regulations, FASB and the SEC. The Auditor
                      change in 1999 was a result of a comprehensive process
                      that included the audit committee and involved all of the
                      public accounting firms.

                      The decision to select Arthur Andersen was made - was
                      based on the assessment that they were the most qualified
                      firm to serve Cardinal at that time.

                      Upon changing from Deloitte & Touche to Arthur Andersen,
                      Deloitte & Touche filed a letter with the SEC confirming
                      that there were no accounting issues or disagreements with
                      the Company that lead to their dismissal. That letter is
                      available to the public as part of the 8K filing that we
                      made relative to the auditor change.

                      Our auditor change from Arthur Andersen to Ernst & Young
                      was precipitated by the difficulties encountered by
                      Anderson as a firm. Once again our decision to change was
                      based upon a comprehensive process that involved the audit
                      committee and all of the public accounting firms.

                      We selected Ernst & Young. Anderson filed a letter with
                      the SEC confirming that there were no accounting issues or
                      disagreements with the Company that lead to their
                      dismissal. That letter is available to the public as part
                      of the 8K filing that we made relative to the auditor
                      change.






                      During these past 19 years we have demonstrated consistent
                      growth, rising returns on sales and capital, increased
                      diversity of earning sources, dramatic increases in
                      internal growth and in share market gains, all done with
                      relatively little debt and straight forward accounting.

                      This is a dramatic story of performance over a very long
                      period of time. We've demonstrated long-term increases in
                      strength in our market and in our financial and economic
                      resources.

                      Ours is not a quick one-time rise that might cause one to
                      consider whether there is a short half light to a shooting
                      star. We are marathon runners and darn good at it.

                      Now the future for us; I want to reaffirm the 2002,
                      reaffirm our fourth quarter expectations are to meet
                      consensus estimates of 73 cents a share. I want to
                      reaffirm that 2002 earnings will therefore reach consensus
                      of $2.63. I would like to reaffirm for 2003 expectations
                      for a 20% earnings growth, again with rising returns and
                      strong cash flow.

                      I want to reaffirm our cash flow expectations for our
                      fourth quarter which is our largest cash flow quarter and
                      affirm therefore our cash flow expectations for the full
                      2002 of $800 million to $900 million. And you will see in
                      2003 similar cash flow as we move into that year.

                      I want to confirm that our debt levels have and will
                      continue to stay conservative. Now why could I have such
                      confidence in the predictability of our future?






                      First of all we are in growth non-cyclical diverse large
                      markets. They're all around health care. We have market
                      leading positions in those markets. We have superior
                      resources.

                      There is a recurring nature of our business and we have
                      long-term relationships with these customers. We continue
                      to investment spend for the future and we build a cohesive
                      strategy built around health care.

                      We know our markets and we know our business well. Let me
                      summarize by saying in the last two weeks I've given
                      presentations at two analyst's conferences and the theme
                      for both of those was growth, rising returns, low risk in
                      uncertain times.

                      How appropriate those themes is for us today. I just
                      didn't realize how uncertain these times are for many
                      investors, but that theme describes Cardinal. I want to
                      confirm growth. I want to confirm that we'll continue to
                      have rising returns and I want to assure that the risks
                      around Cardinal are just the normal risks in any business.

                      They're manageable, they are not large, they are within
                      our plans. And they're certainly not in the area of any
                      past or future misrepresentation of accounting our
                      recordings.

                      I want to open this up to any questions. Operator could
                      you open this up for questions please.

Operator:             At this time I would like to remind everyone if you would
                      like to ask a question please press star then the number 1
                      on your telephone key pad. We'll pause for just a moment
                      to compile the Q&A roster.






                      Your first question comes from (David Risenger) of Merrill
                      Lynch.

(David Risenger):     Thanks very much and thank you for hosting this
                      call Bob. Would you please comment on the current audit
                      process that E&Ys going through for fiscal '02 and just
                      reconfirm that they are not re-auditing fiscal '00 and '01
                      and also just let us know when you expect the audit to be
                      completed and the 10K to be filed.

Bob Walter:           They would - I've got (Dick) here and I'll let
                      (Dick) tell you what the process is. Let me give an
                      overview. It's a normal process when you change from one
                      auditor to the other, you know, I would remind everybody
                      Cardinal had the same auditor for 27 years.

                      We made a change at the time shortly after the merger well
                      with (Allegiance) and chose Arthur Andersen at that time.
                      We would not choose to change auditors, it's not our
                      choice to change auditors but our accounting is so
                      straight forward and our financial systems in place that
                      it's relatively simple.

                      Let me turn it over to (Dick) what the - to explain what
                      that process is. I would say to you - we announced about
                      six weeks ago that our fourth quarter earnings
                      announcement would be on August 6.

                      That's frankly about four or five business days later than
                      normal because I'm in Alaska with my family and I think I
                      ought to be here for our fourth quarter earnings
                      announcement. But any way other than that we would be
                      about three or four days earlier. So the audit will be
                      done way before that.

                      (Dick) you want to comment on the process.




(Dick):               Yes  (David)  E&Y  will be the  auditors  for  fiscal
                      2002.  They  are not  required  and have no need to do any
                      re-auditing  of 2000 or 2001.  Those  audits were
                      performed  by Anderson  and their  audit  opinion  will
                      remain intact.

                      In terms of filing the 10K, you know, we're on our normal
                      timeline to, you know, file our 10K, you know, right
                      around the end of August early September.

(David Risenger):     Great thanks very much.

Operator:             Your next question comes from (Robert Willabe) of Credit
                      Suisse First Boston.

(Robert Willabe):     Thank you do you for - what's left under the share
                      repurchase  program and do you foresee any acceleration
                      there at the current levels?

Bob Walter:           Hey Bob we have a share repurchase authorization
                      of approximately $500 million and I've been saying
                      publicly that I expect that we will have over the next
                      three years in excess of $3 billion of excess cash flow.
                      And I've been saying that I would expect to both invest
                      those funds in new ventures in the Company and to also use
                      some of those funds for share repurchase.

                      We've not announced an expansion to the share repurchase
                      program. I think at the end of the last quarter we
                      announced where we will run this share repurchase program
                      so far of the $500 million (Dick) I think it was something
                      like $100 some million, $116 million so we have a lot of
                      capacity under the current program and we certainly have a
                      lot of cash flow.

                      Our debt at the end of last quarter was below 20%. Debt to
                      total capital as I said we will have extremely strong cash
                      flow in our fourth quarter so




                      I certainly share repurchase opportunities, we're going to
                      be aggressive about it. We just haven't thought through
                      yet, you know, at what level we will - how much we might
                      expand that program.

                      Other questions?

Operator:             Okay your next question comes from (Chris McFadden) of
                      Goldman Sachs & Company.

(Chris McFadden):     (Unintelligible) Bob. Two questions if I might.
                      Firstly is there any element of your pending relationship,
                      your pending merger with (Syncor) that would be
                      potentially dislocated because of some of the share value
                      decline that we've seen, and then secondly you along with
                      900 other companies were included in a list published by
                      the SEC late last week asking for yourself and (Dick) to
                      swore an affidavit concerning financial reporting.

                      Could you just comment on that process and how you and
                      (Dick) would plan to respond to it and under what
                      timeline? Thank you.

Bob Walter:           Okay with regard to (Syncor) the merger agreement
                      is on file and so that's a public document today, the
                      merger agreement is - provides for a fixed exchange ratio
                      and without a collar.

                      And with regard to sworn affidavits I don't know what all
                      the details of it are, I certainly don't have any problem
                      swearing, attesting to the financial health and accuracy
                      of our financial statement. I'm sure (Dick) doesn't either
                      but (Dick) you might comment on - you might comment on
                      what you've read so far.





(Dick):               Yes, you know, on that (Chris) I think it's consistent we
                      have been in prior years provided a management
                      responsibility statement so we've already been taking that
                      responsibility and signing for it personally. I think, you
                      know, just making all companies do that and from a timing
                      perspective I think we're required to do that with the
                      filing of our annual 10K.

(Chris McFadden):     Thank you.

Operator:             Your next question comes from (John Creegar) of
                      (Folum Blair).

(John Creegar):       Thanks very much. Once your first audit is
                      complete with E&Y will you still need to deal with trying
                      to get consent from Arthur Andersen to publish historical
                      financials?

Bob Walter:           Let me ask (Dick) and (Dick) may comment on this
                      whole thing - process. He knows the technical aspects.
                      It's hard to get somebody to attest to something if they
                      don't exist. And I think the SEC contemplated - I think
                      that might be a problem in the future for all of the
                      public clients of Arthur Andersen's, so they provided for
                      exactly what words you can use and how you go about this
                      thing.

                      So assuming there's somebody on the other side to sign
                      something then I would tell you as an example in the
                      Columbus office I'm told that there's less than a handful,
                      less than a handful of people that are still even in the
                      Columbus office, but (Dick) why don't you talk about what
                      is the process.

                      I'm going to say this is not a complicated accounting
                      company for starters and so its relatively easy for a new
                      accounting firm to step in here, but (Dick) why don't you
                      comment on both of those things I...





(Dick):               Yes I guess in terms of when a consent would be required,
                      basically Arthur Andersen are the auditors of record for
                      our fiscal 2000 and 2001 years, so any time we want to use
                      those audited financial statements if Arthur Andersen were
                      still in existence we would have obtained a consent from
                      them in terms of their acknowledgement of our use of that
                      financial information.

                      So in the future any time we have a registration statement
                      or filing where we incorporate those financial statements
                      into that filing, we would have required a consent from
                      Arthur Andersen. We'll avail ourselves of the, you know,
                      the disclosure that we made in the S8 that the SEC has
                      provided, you know, discussing the fact that Arthur
                      Andersen doesn't have the personnel available to provide
                      that consent.

                      So I guess any time you see the 2000 or 2001 financial
                      statements that will be the kind of disclosure you'd
                      expect to see.

(John Creegar):       Great thanks (Dick).

Bob Walter:           I think any  comment  on just on - my comment  on is
                      relatively  straight  forward.  We don't  have
                      complicated partnerships and things like this.  Just a
                      transition from one auditor to another in our case.

(Dick):               I think that is a good point in terms of the ease of
                      transition, I think (Bob) mentioned in his remarks that,
                      you know, 98% of our revenues come from transactions where
                      the produce is delivered and so there's not a, you know,
                      there's not a situation where you have unusually complex
                      or sophisticated off-balance sheet financing or
                      transactions that would make the audit overly complex.





                      Cardinal's not a large company with, you know, a
                      significant business but, you know, in the overall scheme
                      of things I think our accounting is straight forward and,
                      you know, relatively easy for the auditing firm to get
                      their hands around.

Bob Walter:           Okay we'll take one more question and then we'll try and
                      wrap it up here.

Operator:             Your final question comes from (Lisa Gill) of JP Morgan.

(Lisa Gill):          Actually my questions  have been answered and my question
                      was just going to be about the  difficulty of the audit
                      process moving from one to the other.

                      (Dick) if you can just elaborate a little bit though -
                      just being a previous auditor myself - I'm wondering are
                      they going to review the 2001 audit findings from Arthur
                      Andersen. I mean what do they do to get themselves
                      comfortable with Cardinal and as far as the previous audit
                      findings that Arthur Andersen had?

(Dick):               You know, the auditing standards provide for successor and
                      predecessor auditor cooperation and Arthur Andersen has
                      been extremely helpful and willing to cooperate in that
                      process so part of the procedures that E&Y has already
                      performed has been a review of those prior years work
                      papers to allow them to both become educated and help
                      establish their audit base for the 2002 year.

(Lisa Gill):          Okay great thanks.

Bob                   Walter: Okay thank you for attending. I view this as an
                      opportunity, I've seen it before. The pendulum as I talked
                      about, the pendulum between suspicion and trust is shifted
                      for general corporate America. You should be confident in




                      Cardinal, confident about the industry which we compete,
                      confident of our positions and confident in the way we
                      report to you.

                      So we will have our fourth quarter earnings announcement
                      on August 6 and I expect that to be upbeat. Thank you very
                      much.

Operator:             Thank you this concludes today's Cardinal Health's
                      Conference Call.  You may now disconnect.
