Moderator      Ladies and gentlemen, thank you for standing by. Welcome to the
                      AmeriSource Corporation Third Quarter Earnings conference
                      call. At this time all lines are in a listen-only mode.
                      Later there will be an opportunity for questions and
                      answers. As a reminder, today's conference call is being
                      recorded.

               I would now like to turn the conference call over to your host,
                      Mr. Michael Kilpatrick. Please go ahead.

M. Kilpatrick  Good morning, everybody and welcome to AmeriSource Health
                      Corporation's conference call covering third quarter
                      results. I'm Mike Kilpatrick, Vice-President Corporate
                      Investor Relations. Joining me today are David Yost,
                      AmeriSource's Chairman and CEO, Kurt Hilzinger, President
                      and Chief Operating Officer, and Jay James, Chief
                      Financial Officer.

               As always, a caution concerning forward-looking statements and
                      the additional information about the merger with Bergen
                      Brunswig Corporation


                                                               AMERISOURCE CORP.

                                                                          Page 2



                      contained in the company's earnings news release also
                      apply to this conference call. AmeriSource assumes no
                      obligation to update the matters discussed in this
                      conference call and this call cannot be taped without the
                      expressed permission of the company.

               As most of you know, AmeriSource looks to forums, such as this,
                      as our primary vehicle for communicating our results. I
                      want to welcome many of you who may be joining for the
                      first time and are listening via our Web site. On the
                      AmeriSource Web site under Investor Relations you will
                      find a short slide presentation covering some of the
                      points we will discuss today and you are welcome to follow
                      along. As in the past, those connected by telephone will
                      have an opportunity to ask questions after our opening
                      comments.

                      Here is Dave Yost, AmeriSource Chairman and CEO, to begin
                      our remarks.

D. Yost        Good morning, everyone and thank you for joining us. The June
                      2001 quarter was another outstanding performance for
                      AmeriSource where our demonstrated ability to focus on
                      execution again resulted in a record quarter in revenue
                      and earnings. As noted in the press release, our revenue


                                                               AMERISOURCE CORP.
                                                       Host:  Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                          Page 3

                      for the quarter, excluding negligible bulk shipments,
                      reached a record $3.5 billion, increasing about $600
                      million over the same period last year. That's a strong
                      20.5% increase. Good, solid revenue growth in this
                      quarter, and 20% as well, for the first nine months of our
                      fiscal year. Our bottom line performance was also a record
                      for June quarter with net income of 25% over the same
                      period last year. EPS for the quarter reached a record
                      $0.57, a 21% increase over the $0.47 earned last year,
                      which excludes the reversal of restructuring reserves in
                      the prior year.

               We achieved these record results despite the impact of Health
                      Nexus, formerly known as New Health Exchange, which cost
                      $0.02 per share this quarter and merger expenses which
                      cost an additional $0.01. We continue to be disciplined in
                      controlling our operating expenses to a record low as a
                      percent of revenue and in managing our assets. The result
                      was a robust return on committed capital of 26.4%, the
                      best single measurement of our performance.

               As noted by the $900,000 in merger-related charges, the work is
                      well underway to achieve the successful integration of
                      AmeriSource and Bergen Brunswig Corporation following the
                      close of our merger. We have filed all of the documents in
                      response to the Commission's second request for


                                                               AMERISOURCE CORP.
                                                       Host:  Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                          Page 4




                      information, but we have delayed certification at the
                      request of the FTC staff. Importantly, we would
                      characterize this request as routine given the size of the
                      transaction and what has been viewed as a quick response
                      to the FTC's information request by the companies. We
                      expect to certify shortly, and as most of you know, once
                      we certify, the Commission has a 30-day review period,
                      after which, if there is no objection, the merger will
                      proceed. We remain on schedule to complete the merger of
                      these two strong, service-oriented companies by the end of
                      August following shareholder votes and the Federal Trade
                      Commission review.

               Our integration activities are moving forward smoothly under the
                      direction of Terry Haas and supported by Deloitte
                      Consulting. Terry has extensive corporate and field
                      experience at AmeriSource and was the unanimous choice of
                      AmeriSource and Bergen to head this important function.
                      Deloitte Consulting was unanimously selected to assist in
                      the integration effort by a steering committee of
                      AmeriSource and Bergen Brunswig executives after
                      interviewing a number of qualified candidates. Kurt and I
                      will continue to be actively involved in the integration
                      process, of course.

               We have completed phase one of the integration, gathering the
                      data needed to understand each company's business
                      processes using ... in some circumstances to


                                                               AMERISOURCE CORP.
                                                       Host:  Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                          Page 5

                      avoid compromising competitive information. In phase
                      two we are completing the details of the day one
                      activities and laying out in detail the integration
                      activities that will follow the close. The third and final
                      phase will be the implementation. Combining these two
                      companies is a large and challenging task and the efforts
                      of the associates in both companies has been
                      extraordinary.

                      Both companies have extensive integration experience and
                      their successful track record is proving a tremendous
                      asset to the planning process. As the process has
                      progressed, we remain confident that at least $125 million
                      of pre-tax operating cost synergies will be delivered by
                      the end of year three. As a reminder, this kind of
                      integration work is what this industry and these companies
                      have done successfully numerous times as acquisitions were
                      made and these companies created.

                      Turning to industry issues, the Medicare drug benefit
                      continues to be in the news with the latest developments
                      being the Bush administration's drug discount card and the
                      Senate Democrats talking about passing a Medicare
                      pharmaceutical benefits plan. Although it is unclear
                      exactly how the cards will work or even if that is the
                      mechanism that will be

                      utilized, nearly all scenarios, including pending
                      legislation, point to added volume for the industry and
                      AmeriSource, which of course, will be incremental, handled
                      at a very low additional cost, and we expect, generate
                      incremental profits.

                      Reimportation of pharmaceuticals was again raised in
                      Congress with the House passage of an amendment allowing
                      reimportation of pharmaceuticals for personal use. Because
                      of the safety and liability concerns, we don't believe
                      reimportation legislation will pass. Although, with our
                      repackaging facility we would be well positioned to take
                      advantage of this type of opportunity should we elect to
                      do so.

                      The shortage of pharmacists has also been in the news
                      lately, and as many of you know, AmeriSource has been
                      addressing this critical industry issue with the
                      development of a central processing center called
                      Autonomics. Introduced in testing last year, it has been
                      certified by the Ohio State Board of Pharmacy and is in
                      operation in Ohio. The program significantly reduces over
                      20% of the pharmacists' time spent on prescription
                      adjudication and other processing activities, increasing
                      productivity, and providing pharmacists more time to
                      assist patients and run the pharmacy.

                      The industry remains strong. According to the latest IMS
                      health data, pharmaceutical sales this year will be well
                      ahead of last year and dollar sales are expected to
                      increase at a compound annual growth rate of almost 14%
                      over the next five years, which we consider to be
                      conservative. It is not economic growth that is fueling
                      this expansion, but rather the demographic impact of the
                      aging of America, increased utilization of existing
                      medications, and new products.

                      Regarding the manufacturer's pricing environment, we do
                      not see any fundamental change occurring and anticipate
                      none going forward. While it is always difficult to
                      predict exactly when manufacturer's price increases occur,
                      we do not think there will be a fundamental change to the
                      roughly 4% annual price increases that have been
                      experienced in the last few quarters.

                      Health Nexus, the new name for the New Health Exchange,
                      our industry initiative with several other distributor
                      investors, continues to move actively forward. Health
                      Nexus released their first product at the end of March and
                      expect two additional releases soon. For those of you who
                      are not familiar with Health Nexus, the investor's plan is
                      to make this an

                      important utility that will allow all distributors and
                      manufacturers to lower cost in the healthcare supply
                      channel by moving together to common transaction formats
                      that none of us can implement alone. Significantly, it is
                      a complement to our own proprietary technology
                      initiatives, such as AmeriSource's iECHO ordering and
                      inventory system.

                      Our ability to sustain growth remains anchored in our
                      passion for customer service. We continue to strive to
                      improve our service, and we empower our distribution
                      center general managers and regional managers to make the
                      key customer decisions locally and quickly. Earlier this
                      year two national acute care purchasing organizations,
                      Novation and Premier, again voted AmeriSource number one
                      in customer service among the national pharmaceutical
                      distributors.

                      It was another terrific quarter for AmeriSource. We
                      delivered strong sales momentum. We controlled our
                      expenses and receivables. We delivered record third
                      quarter profits, and continued our disciplined deployment
                      of assets with a robust return on committed capital of
                      over 26%. We again demonstrated that we focus on more than
                      revenue. We are very excited about our pending merger with
                      Bergen Brunswig, and we are doing the

                      integration planning work carefully so that the execution
                      will reflect the performance you have come to expect from
                      AmeriSource. These are truly exciting times for our
                      company.

                      Now I want to turn the floor over to Kurt for some
                      operational specifics and then Jay will cover the
                      financials.

K. Hilzinger   Thank you, Dave, and good morning everyone. As Dave mentioned,
                      this was another very strong, well-balanced quarter from a
                      sales and operating standpoint. Our sales growth in the
                      quarter was driven by our ability to add new accounts
                      while growing our current base of business. Importantly,
                      during the quarter we continued to focus our efforts on
                      those new customer opportunities where we could achieve an
                      adequate return on committed capital and where our higher
                      service capability and offerings will be recognized.

               Jay will detail the specific customer group statistics, but in
                      terms of highlights, in our market leading health systems
                      group, we again benefited from the full impact of the $500
                      million annualized net new business from Novation, which
                      we were awarded late last summer. In addition, we continue
                      to add


                                                               AMERISOURCE CORP.

                      new hospital and acute care business and renew agreements
                      with a number of long-standing AmeriSource customers. In
                      the Alternate Site group we gained numerous mid-sized and
                      smaller accounts during the quarter while enjoying the
                      positive impact of the large Anthem Prescription
                      Management contract, which began late last year.

                      Our retail business continued to show accelerated growth.
                      During the quarter we were awarded an incremental $200
                      million annualized contract with Family Meds Group, Inc.,
                      a rapidly growing national drugstore chain. While we have
                      been doing business with Family Meds since January, we
                      believe this additional reward was the result of our
                      demonstrative responsiveness to Family Meds' needs and our
                      overall customer service.

                      We continued our focus on the independent and retail chain
                      customer segments. These retail customers rely on and pay
                      us for our many value-added programs and services. In
                      fact, later today Dave and I will be headed to our annual
                      trade show for these customers, which are being held this
                      week in Nashville. This forum provides a unique
                      opportunity for us to interface directly with these
                      customers and hear about their needs and challenges.
                      Meeting attendance will be a record, with more than 1,000

               customers and hundreds of suppliers participating.


               In addition to contributing to the pharmacy profession through a
               number of continuing education and technology training programs,
               during the trade show we will showcase our many existing
               programs, introduce new programs, and seek our customers' input
               on new offerings currently under development.

               For example, at the show we will launch a version 3.0 of our
               highly successful iECHO ordering and inventory management portal
               designed to help pharmacies better manage their inventories with
               accurate, real-time information. iECHO has been growing in
               popularity with nearly 5,000 customers actively using the system.
               Version 3.0 upgrades, which are based on input from our pharmacy
               customers, include new group reporting capabilities, hand held
               order unit uploading, as well as a new on-line inventory
               reporting function. This industry-leading technology offering has
               been instrumental to our ability to capture new business.

               At the trade show we will also be releasing our latest edition of
               AmeriSource Index, our quarterly survey of key issues facing the


                                                               AMERISOURCE CORP.

               pharmacy profession. We introduced this index this spring and
               it's begun to gain broad acceptance, with three appearances in
               USA Today and numerous trade press articles. The index is part of
               a broader strategy to expand AmeriSource's presence in the health
               care supply chain.

               Let me turn to some of our own productivity initiatives for the
               moment. During the quarter our centralization program, which we
               completed last year, continued to contribute to our results, most
               notably in terms of record low operating expense performance and
               improved procurement performance. Total operating expense as a
               percentage of operating revenues, including all IT costs,
               corporate overhead, and related expenses increased only 3.5%,
               including $900,000 spent on merger integration activities. That's
               an improvement of 39 basis points over the prior fiscal year to
               an all-time record low of 2.41%, and down sequentially in dollar
               terms from the March 2001 quarter. Record low operating expense
               ratios were reported in each of our 22 pharmaceutical
               distribution centers for the quarter.

               Significant productivity gains were achieved in IT, warehouse
               operations, and selling expenses, the very areas our
               centralization initiative was



                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 13

               designed to address. On a year-to-date basis, our operating
               expense ratio is 2.47%, putting us on track to meet our full-
               year target of below 2.5%.

               In addition, two major technology initiatives were completed
               this quarter, which will provide further productivity gains.
               First, we completed the implementation of a new best in class
               procurement system. This system, in combination with our now
               centralized procurement function, generated an improved vendor
               margin contribution compared to year ago levels. During the
               quarter we successfully sourced more buying opportunities, and
               executed on those opportunities at more optimal levels while
               continuing to target returns on capital of greater than 20%.

               Further, as Jay will comment on in a moment, we completed a
               highly successful implementation of a new, company-wide
               financial and accounting system, which will allow us to improve
               our closing cycle, strengthen our general management
               capabilities to improve the access to data, and capture
               additional staff savings.

               Strong capital management discipline was again in evidence this
               quarter. Our net working capital investment as a percentage of
               sales improved over



                                                               AMERISOURCE CORP.

                                                                         Page 14


               year ago levels, driven by a very strong one point day
               improvement in days sales outstanding, offset in part by an
               increase in inventory levels to take advantage of attractive
               vendor margin opportunities we sourced during the quarter.
               Lastly, our new Atlanta facility, which supports the new
               Novation business gained in the Georgia market, began shipping
               during the quarter and is running smoothly. Atlanta met our
               expectations as a modest contributor to operating income in the
               quarter.

               I want to make clear that in all of these efforts, both recent
               and going forward, we remain committed to a highly responsive,
               locally driven customer service model. This is the backbone of
               our competitive edge and we will continue to enhance it. We will
               continue to perform at the local level those activities that
               directly touch our customers.

               While during the quarter we have been actively engaged in a
               number of merger approval and integration activities, it's clear
               that based on the level of activity I've just outlined and the
               results of the quarter, that we remained focused on our
               business. In the third quarter fiscal 2001, we continued to
               build momentum, which gives us a high degree of confidence

               in AmeriSource's performance in the coming quarter and for the
               year.

               Now I'll turn the call over to Jay to review the financial
               results for the quarter.

J. James  Thanks, Kurt. Good morning, everyone. This clearly was a well-balanced
               quarter with strong improvements in a number of areas including
               revenues, earnings, return on committed capital, and the balance
               sheet. The future continues to look strong and I'll talk more
               about that at the end of my comments.

     Before I begin, let me mention that my comments and year-to-year
               comparisons will exclude special items for the third quarter of
               2000. You will remember that in that period we reversed previous
               and no longer necessary restructuring reserves, which added about
               $0.01 to the quarter. At that time we viewed the quarter as a
               $0.47 quarter rather than the $0.48 reported. That is still our
               point of reference.

     Now let me give you the particulars of the quarter. Overall operating
               revenue for the quarter came in at a robust $3.52 billion. The
               revenue growth for the


                                                               AMERISOURCE CORP.

                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 16

               quarter at 20.5% reflects continuing top-line momentum and the
               impact of a number of new accounts, both large and small, as well
               as growth in existing accounts. This brings sales for the first
               nine months to $10.3 billion, up 20.1% from the same period of
               2000.

          Let me give you more details on our institutional retail sales
               breakdown. For the quarter, our hospital or health system sales
               were 42% and Alternate Site was 12%, totaling 54% for
               institutional. Independents were 32% and non-warehousing retail
               chains accounted for 14% or 46% in total for retail. The
               comparable numbers for third quarter 2000 were health systems,
               42%; Alternate Site, 9%; Independents, 37%; and retail chains,
               12%. This represents strong double-digit growth in all areas
               except independents, which were up 5%. This primarily reflects
               the discontinuation of business with a retail buying group. On a
               same store basis, growth continues at a double-digit rate for the
               independents.

          Our gross margin in the quarter, as expected, declined by 32 basis
               points. The year-to-year decline reflects the net impact of a
               number of factors, including the changing customer mix to a
               higher level of larger institutional accounts and the continuing
               competitive environment, partially offset by improved


                                                               AMERISOURCE CORP.

                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 17

               vendor margins compared to third quarter 2000. For the nine
               months, the year-to-year decline in gross margin was 23 basis
               points. The LIFO provision for the quarter was a charge of $5.2
               million compared to a charge of $4.2 million in the same period
               of the prior year. For the first nine months, the LIFO charge was
               $8.8 million versus $8.4 million in fiscal year 2000.

          Total operating expense for the quarter was $84.7 million, up from
               $81.9 million in the prior year third quarter. The $81.9 million
               excludes the impact of the reversal of the $1.1 million in
               previously accrued restructuring reserves. These operating
               expenses include depreciation and amortization costs of $4.2
               million in third quarter 2001 versus $3.9 million in the prior
               year. Four hundred sixty-one thousand dollars of this quarter's
               $4.2 million in DNA represents amortizations, which are at about
               the same level as the prior year. The increase in DNA is
               primarily due to depreciation, which reflects the higher capital
               expenditures due to some of our project implementations.

          Looking at total operating expense as a percentage of operating
               revenue, this represents an improvement of 39 basis points to
               2.41% from 2.80% in the prior year. This reflects, in part, our
               changing customer mix and efficiencies of scale,


                                                               AMERISOURCE CORP.

                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 18

               as well as the continued elimination of cost and continued
               productivity improvement throughout our distribution network. It
               also reflects bad debt expenses of $3.8 million in this quarter
               versus $5.3 million in third quarter 2000, implementation
               expenses relative to a number of our new systems and project
               initiatives, and $903,000 in merger integration planning
               expenses, which equates to about $0.01 per share. For the first
               nine months, operating expenses increased 7.9% to $255 million,
               while total operating expenses to operating revenues decreased 28
               basis points to 2.47% from 2.75%.

               Our operating income for the quarter increased by 26% to $60.2
               million. We showed an increase in operating margin of seven basis
               points year to year to 1.71%. For the first nine months of 2001,
               operating income increased 23.4% to $178.5 million and the
               operating margin improved by four basis points to 1.73%. The
               operating margin was impacted by the lower gross profit margin,
               but more than offset by the lower operating expense as a
               percentage of sales.

               Our results reflect the impact of the investment in Health Nexus,
               which is currently being accounted for on the equity method and
               which we are


                                                               AMERISOURCE CORP.

                                                                         Page 19

               showing as a separate line item below operating income. This
               reduced income by approximately $2 million pre-tax or about $0.02
               per share for the quarter, and $4.6 million pre-tax or about
               $0.05 per share for the first nine months.

               During the last conference call, I mentioned that we had
               successfully completed the first phase of our new financial
               systems project, which gives us better and more timely
               information. We now have successfully completed the second phase,
               which includes the centralization of our accounts payables
               process. This will allow us to reduce the head count associated
               with this function and generate a very good return on committed
               capital on the systems investment.

               Interest expense for the quarter decreased to $7.4 million from
               $8.4 million in 2000. The interest expense reflects higher
               average levels of debt offset by lower borrowing costs due to the
               lower spreads and lower interest rates, as well as the impact of
               the convertible financing. Average gross borrowings for the
               quarter were $532 million versus $505 million a year ago. Ending
               debt was $643 million versus $534 million in third quarter 2000.
               Cash increased to $94.3 million from $36.2 million in third



                                                               AMERISOURCE CORP.

                                                                         Page 20

               quarter 2000. Therefore, on a net debt basis, reducing debt in
               both periods by cash, this year-to-year increase would be about
               $50 million. This year-to-year increase in debt reflected, among
               other factors, significant discretionary inventory opportunities,
               which made additional investment attractive. We would expect a
               significant amount of these discretionary inventories to be sold
               in the September quarter.

               Our borrowing spread under our existing revolving credit facility
               is currently at 37.5 basis points over LIBOR, reflecting our
               improved financial structure. For the quarter, average three-
               month LIBOR rates were down over 200 basis points compared to the
               same period the prior year. We continue to have ready access to
               the capital markets to meet the needs of our business, and I want
               to remind everybody that during the September quarter we did
               complete the issuance of $300 million in convertible debentures
               with a fixed interest rate of 5%. These bonds represented a
               valuable addition to our capital structure and should be
               accretive to earnings as we go through 2001 on a diluted basis.
               However, they do impact the calculation of EPS as explained by
               the supplemental table in the earnings release.

               The effective tax rate for the quarter, as expected, was 38%.
               This is the same as the 38% for third quarter 2000 and year to
               date 2001. Average shares outstanding in the quarter of 52.9
               million increased by 1.3 million from third quarter 2000,
               primarily due to option exercises. Diluted shares of 59.6 million
               for the quarter increased by 7.5 million from third quarter 2000
               reflecting the dilutive impact of stock options, and 5.7 million
               shares reflecting the issuance of convertible notes in December
               2000.

               Bringing this all to the bottom line, we delivered net income of
               $31.5 million, up 29% before special items in 2000. Diluted EPS
               for the quarter was $0.57, an increase of 21.3% versus the $0.47
               of third quarter 2000, again excluding the special items
               mentioned earlier. For the first nine months, net income was up
               26.9% to $89.2 million, and diluted EPS was $1.64, an increase of
               20.6% over the $1.36 for the first three quarters of fiscal year
               2000, again excluding the special items in 2000. Please note that
               EPS for 2001 rounds up to $1.64 for the first nine months versus
               the sum of the $0.49 reported in the first quarter and the $0.57
               reported in both the second quarter and in this quarter.

               Moving to the balance sheet, for the quarter DSOs were down to a
               record

               17.2 days from 18.6 days a year ago. With the improvement driven
               both by customer mix as well as a strong focus on asset
               management at the local level. DPOs were up to 45 days versus
               39.6 days a year ago, reflecting the timing of inventory buying
               opportunities. Inventory levels of $1.96 billion were increased
               from prior year levels, and reflected necessary inventories to
               support the 20% revenue increase as well as the previously
               mentioned inventory buying opportunities. As a result, inventory
               turns decreased to 6.7 versus 7.2 a year ago. However, our net
               working capital investment as a percentage of sales for the
               quarter improved slightly to the lowest level in the last several
               years at 6.70% versus 6.71% at third quarter 2000 despite the
               increased level of inventories. Capital expenditures in the
               quarter were $5.9 million versus $4.7 million one year ago,
               reflecting the previously mentioned systems projects.

               Turning to return on committed capital, which you will recall is
               our primary financial metric in which we define as operating
               income excluding amortization, divided by fixed assets plus
               inventory and receivables less payables on a rolling 12-month
               basis. This reached a very strong level of 26.4% this quarter,
               continuing well above our stated target

               of 20% or better. This continues to reflect our disciplined use
               of capital and reflects a continuing trend of improvement from
               already impressive levels.

               Looking ahead to the rest of fiscal year 2001. We continue to be
               comfortable with a revenue growth rate of 20% for fiscal year
               2001, which is clearly well above our long-term target of 15%. We
               also continue to be confident that strong cost discipline and
               additional productivity improvements, as well as changes in our
               customer mix, will deliver a lower operating expense for the
               year, below 2.5%. We anticipate good vendor margin opportunities
               will continue and we expect to be able to increasingly benefit
               from them. As a result, we are comfortable with the current
               analyst estimates for the year. These estimates reflect a
               consensus number of $2.27 for the year, which represents an
               increase of 20% over the $1.89 of fiscal year 2000. Importantly,
               we still anticipate ending the year with positive free cash flow
               of at least $50 to $100 million, driven by inventory reduction.
               All in all, a very solid quarter and the expectation for a very
               solid year.

               For a longer-term perspective, let me take a moment to remind you
               that we


                                                               AMERISOURCE CORP.

                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 24

                    are now in the middle of our normal, extensive, bottoms-up
                    planning process. This would normally lead to a guidance on
                    the outlook for fiscal year 2000 at our fourth quarter
                    conference call. This year we are clearly involved in an
                    equally intensive integration process addressing the
                    expected merger of two strong businesses. While it is still
                    too early to give guidance for next year on either basis,
                    let me reaffirm our continuing long-term financial goals,
                    which will also apply to the combined companies, and those
                    are to achieve at least 15% revenue growth, 20% return on
                    committed capital, and 20% EPS growth.

                    Now let me turn you back to Mike.

M. Kilpatrick  Thank you, Jay. We will now open the call to questions. I would
                    remind you to limit yourself to one question with a follow
                    up until all have had an opportunity. Then you may ask
                    additional questions. Go ahead, Alan.

Moderator      Thank you. We'll take a question from the line of Ray Faltche
                    with Bear Stearns. Please go ahead.

R. Faltche     Yes. Good morning. It's Ray Faltche with Bear. You touched
                    briefly in the


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 25

               prepared remarks on the inventory build that we saw on the
               balance sheet, and I guess a little bit of an increase in the
               short-term debt. You talked about significant discretionary
               opportunity. I was wondering if you could put a little bit more
               color around that, if you think that's going to be an ongoing
               opportunity for the next several quarters, or was there something
               special in this last period that gave you some opportunity?

J. James     Again, one thing I would point you to is that we do expect to
               significantly reduce those inventory levels in the next quarter,
               and again, that's one of the key drivers on cash flow.

K. Hilzinger Ray, this is Kurt. I'll comment on the question a little bit from
               the standpoint that I think it's been an ongoing initiative here
               at AmeriSource to increase our procurement capabilities over the
               last year to 18 months. I think we're starting to see that come
               to fruition here a little bit. We've got new systems. We're now
               centralized. The net effect of what we're finding here is we're
               seeing more opportunities to make some buys than we have before.
               But, as always, we remain disciplined in our use of that capital.
               Those discretionary investments go in with an intent to return no
               less than 20% on a capital basis.


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 26

             So with regards to a forward look here, as long as our procurement
               function continues to find opportunities and we can get at least
               a 20% return, we will continue to put the capital to use that
               way. In a 4% steady inflation environment, which is what we're
               anticipating, I think we're going to continue to have great
               opportunities in future periods.

R. Faltche   Great.  I appreciate that.  Thanks.

K. Hilzinger Yes.

Moderator    Pardon me. Then for our next question we will go to the line of
               Glen Santangello. Please state your firm followed by your
               question.

G. Santangello Yes. It's Glen Santangello from Salomon. David, I just have a
                    couple of quick questions related to the merger. You know
                    you gave us some comments earlier, but with respect to the
                    FTC process, could you just sort of give us the background
                    for why you decided to delay the certification? Was it the
                    FTC that maybe gave you an indication up front that it might
                    take them longer than 30 days to begin with or you just
                    thought it would be a good


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 27

                    idea? Isn't it my understanding that the information has
                    been in their hands for quite some time?

                Then sort of as a follow up to that, I know as part of their
                    review process they also solicit customer feedback, and if
                    you can give us a sense for how they do that and sort of how
                    that's progressing at this point? I know in the past we
                    talked about one GPO, potentially in the Midwest, that was
                    squawking a little bit and I think there were some
                    independents on the West Coast. So if you could just give us
                    some additional color on those issues I think it'd be
                    helpful.

D. Yost         Okay, Glen. First of all, in terms of the schedule, we really
                    view the schedule that we're on right now as very routine,
                    particularly given the size of this transaction, which was
                    very, very large. Some observers would point out that we
                    responded to the FTC's request faster than they expected us
                    to do. We responded very, very quickly. So the request for
                    delay is coming from the Federal Trade Commission, but we're
                    looking to accommodate that. But again, I want to stress the
                    word here, routine, because we really think that we're
                    progressing exactly as we thought we would all along, and I
                    think from the get-go back in March we were talking about
                    this transaction


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 28

                    closing the end of August and we're still absolutely there.

                In terms of the customer response, Glen, you know, we think
                    we've gotten very favorable support from our customer base.
                    As Kurt and I mentioned, we're on our way to our annual
                    trade show where we'll see a lot of these customers eyeball
                    to eyeball, but I have talked with a large number. We will
                    deliver to the FTC, literally hundreds of letters of support
                    from our customers. So we do not think adverse customer
                    reaction will be an issue here at all. In fact, we think
                    that the customers will be very supportive of this
                    transaction in part because they view this as the coming
                    together of two service-oriented companies, which gives them
                    a strong alternative in the marketplace. So we're very
                    optimistic about the support we've gotten and will get from
                    our customers.

G. Santangello  Can you just remind me, you know I hate to bring up the past,
                    but back, last time around, did you receive favorable
                    customer support last time around? What sort of reaction did
                    the customers have back in '98?

D. Yost         Actually, Glen, it was a little mixed last time. We had some
                    customers, some buying groups, who were opposed to the
                    transaction. We would note that


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 29

                    the transaction we're bringing forward today is dramatically
                    different than the situation last time. Some customers
                    perceived that only having two large wholesalers last time
                    around as decreasing their choice. This time around most
                    customers perceive the playing field, in some sense, being
                    even more level with three wholesalers of similar size; two
                    very service-oriented customers coming together. So last
                    time there was some adverse reaction, not this time around.

G. Santangello  Okay.  Thanks for those comments.

D. Yost         Okay, Glen.

Moderator       And for our next question we go to the line of Michael
                    Fitzgibbons. Please state your firm followed by your
                    question.

M. Fitzgibbons      Good morning. It's Morgan Stanley. Could you just tell us
                    about whether you're working with Bergen on the roll out of
                    your new financial procurement systems and to what extent?
                    Are they already implementing or is there input there or are
                    you coordinating that roll out or is that something that
                    you're going to have to sort of start over at Bergen once


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 30

                    you close the deal?

D. Yost         Michael, we've got a very intense, disciplined integration
                    process under way. It's headed up, as I mentioned in my
                    remarks, by Terry Haas who was unanimously selected by both
                    companies. We've hired Deloitte Consulting. They have
                    identified a number of threads of what they say are
                    disciplines. That process is moving along very well.

                We have not made final decisions on what systems will be used,
                    including procurement systems, but one of the things that's
                    being encouraged is by how robust we have found both systems
                    to be.

                Kurt, do you want to add anything?

K. Hilzinger    I would just kick in that Deloitte is doing a review. One of the
                    rationales for selecting Deloitte, frankly, was that they
                    knew Bergen's systems up and down the line. They've done a
                    lot of work with Bergen through the years so they started
                    with a leg up. They are in the process of doing a very
                    comprehensive capability study for both sets of systems.


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 31

               I think it's important to note this may not be an either/or
                    decision here. There may be elements of either system that
                    can be put together to have the system supporting the
                    combined entities being more capable than either one
                    independently. Procurement is a good example. We've gone to
                    a state of the art procurement system here. Bergen was under
                    review with its own analysis to whether they wanted to
                    upgrade their procurement system. This made a logical place
                    where we've, in fact, saved the combined company a step here
                    because we've already got it in place and running well.

M. Fitzgibbons      Did you consider ever holding off on implementing these two
                    systems until those reviews with Deloitte and Terry Haas and
                    everybody else were complete?

D. Yost        We actually had committed to our system last fall, so we were
                    well underway in our own process and we just elected to move
                    forward with it because there was money to be gained for our
                    shareholders.

K. Hilzinger   That's true for both systems.

M. Fitzgibbons      Okay. And one other question. Did you say what the bad debt
                    charge was


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 32

                    in the quarter?

J. James       Yes. It was $3.8 million in the quarter, which again, runs a
                    little bit higher than what our expectation would be.

M. Fitzgibbons      Okay. Hasn't that been the case for a number of quarters
                    now? I remember last summer you mentioning that you felt
                    like you'd be back to sort of $1.5 million.

J. James       Right. Well, we ran $3.7 million in the first two quarters, $3.8
                    in the third quarter. That takes us to a rate that's about
                    11 basis points of sales. I would expect on a normal basis
                    that to be more in the eight to nine basis point range. So
                    we are running a little higher than normal and we do expect
                    to trend back to those lower levels in the future.

D. Yost        I would also point out that if you looked at our bad debt
                    reserves as a percent of our total revenues, I think that
                    you would find that they are very strong in the industry.
                    We're kind of a conservative group.

J. James       Yes. We have a total reserve out there now of $40.2 million,
                    which is approximately 3% of sales, and again, when you
                    consider that a significant

                                                                         Page 33

                    portion of our sales base is the government, which is a
                    pretty good credit risk. Those are pretty good numbers.

M. Fitzgibbons      Okay. And was there anybody in past quarters when you've
                    been...particular customers involved, you know, like Grand
                    Union in general. Is there anybody this quarter that led to
                    a...?

D. Yost        Yes. Nobody really visible out there. Previous quarters it's been
                    the jitneys and the Grand Unions and the Response
                    Oncologies. This quarter there was, I think, one small
                    hospital group out there, but nothing significant.

M. Fitzgibbons      Okay.  Thanks very much.

D. Yost        You bet.

Moderator      And next we will go to the line of Robert Willeby with Credit
                    Suisse First Boston. Go ahead, please.

R. Willeby     Thank you. Can you give us an idea as to the merger costs you
                    might be expecting for July and August? And is it reasonable
                    to assume, maybe,


                                                               AMERISOURCE CORP.

                                                                         Page 34

                    Bergen's incurring similar types of costs?

D. Yost        I really can't comment, Bob, on what to expect from Bergen.

J. James       And I would say the activities will clearly, I can't say
                    specifically about July and August, but they'll clearly step
                    up following the merger. That's when, you know, there'll be
                    more things going on.

R. Willeby     Okay. And just from the standpoint of the Autonomics unit, you
                    said it's up and running in Ohio. Can you give us an idea of
                    the customer base and maybe the economics of a customer
                    relationship?

D. Yost        We're really uncomfortable talking about specific customers, Bob,
                    but I will tell you we mentioned that Kurt and I are on our
                    way to the trade show. We hope to have a lot more customers
                    at this time next week than we have now. But this saves the
                    pharmacist a considerable amount of time. As you're well
                    aware of, pharmacists are becoming very expensive people.
                    There's a huge shortage of them. The national association of
                    chain drug stores is estimating that shortage at some 7,000
                    physicians across the United States. So this is going to
                    really allow the pharmacist to be a lot


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 35

                    more productive. It really kind of kicks in that that amount
                    where the pharmacist is filling, say, 110 prescriptions or
                    so, and wants to increase his productivity, and he's right
                    at that verge of do you hire another pharmacist or do you
                    try to come up with a system to become more productive and
                    that's when Autonomics kicks in. So we're very excited about
                    this and we think a large number of our regional small
                    chains and entities will be as well.

R. Willeby     How do you get paid, though, I guess? That's what I'm trying to
                    figure out.

D. Yost        We get paid for the service on a per scrip charge.

R. Willeby     Excellent. Thank you.

D. Yost        You bet.

Moderator      Thank you. For our next question we will go to the line of Seth
                    Tesch and Mr. Tesch is with First Union. Please go ahead.

S. Tesch       Hi. Good morning. Should we view the merger charge this quarter
                    kind of like


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 36

                    we did for the quarter last year where this is really a
                    $0.58 quarter versus a $0.57 quarter? How would you ask us
                    to view that going forward?

J. James       Seth, this is Jay. We left it in, if you read our normal results
                    this year, because we haven't closed the merger yet. I think
                    going forward we'll look at it as being separate. You can
                    view it how you want to, but that's the way we reported it
                    and it ties in, clearly, with a 20% growth rate, which is
                    clearly our long-term financial target.

S. Tesch       Okay. Great. And then secondly, I was curious to know, with your
                    LIFO provision being about $9 million for the first nine
                    months of the year, I was curious to know what your target
                    would be for LIFO for the fourth quarter or the fiscal year?

J. James       Again, each quarter's LIFO charge or credit is based on our
                    outlook at that time, and as we've stated, we had higher
                    inventories in the June quarter than we expect to have in
                    the September quarter, which is all part of the calculation.
                    Again, we have to manage this on a quarter-to-quarter basis.
                    The one thing I will point out to you is that, historically,
                    we have in the last four years ended up with a credit in the
                    fourth quarter. And again,


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 37

                    history may not be an indicator of the future, but I'll just
                    point out that we have ranged in that credit from $1 million
                    to $8 million for the last four years.

S. Tesch       But no guidance as to where you think that's going to come in?

J. James       No. I mean I think we'll clearly do our best to bring it in at as
                    a low a level as possible, but we believe that the charge in
                    the third quarter was appropriate for the circumstances.

S. Tesch       Great. And then lastly, I just wanted to make sure. You can't
                    have your shareholder vote until after you hear from the
                    FTC, is that correct?

D. Yost        That is not correct. That's not correct, Seth. We can have the
                    shareholder vote whenever we schedule it. It is not unusual
                    for companies to have shareholder vote before you hear from
                    the FTC.

S. Tesch       Okay. But you don't have it scheduled as of yet?

D. Yost        It is not scheduled as of yet.

S. Tesch       Great. Thanks very much.

Moderator      And for our next question we go to the line of Ray Louis with
                    McDonald Investments. Go ahead, please.

R. Louis       Thank you. Good morning, everyone. Just a couple of quick ones
                    that I missed in the prepared remarks. Jay, what was the cap
                    ex number in the quarter?

J. James       The cap ex was $5.9 million.

R. Louis       $5.9 million?

J. James       Yes.

R. Louis       Okay. And at this point you don't have any indication in terms of
                    what the total magnitude or timing of charges might be
                    relative to the Bergen transaction, is that correct?

J. James       No. We would want to complete the process and we would prepare to
                    tell you what we can following the completion of the merger.


                                                               AMERISOURCE CORP.

R. Louis       Okay. And perhaps backing up just a little bit on a more general
                    kind of question, just looking at the overall market and the
                    sort of 13 or 14% growth rate for the aggregate, and
                    obviously, the expectations that you guys have to probably
                    be slightly ahead of that, and likewise, some of your
                    competitors out there. Could you guys talk a little bit
                    about who you're taking share from and what the outlook
                    continues to be in terms of that front just given the growth
                    in the total pharmaceutical market?

J. James       We try to be a non-discriminatory share grabber when we have a
                    chance, Ray. We take it from whoever we can get, whenever we
                    can get it. So I think it really varies. I mean we've got
                    strong revenue growth in all of our segments. We've picked
                    up a lot of singles and doubles, as Jay likes to talk about
                    with our independents. We've made several strides in the
                    regional chains. Some of these regional chains are large,
                    you know, well over 100 stores. I'd say the places where you
                    have not seen us as of late is in these big contracts that
                    have moved from time to time. Frequently that's because we
                    perceive them to be very price sensitive. So we're out there
                    trying to get customers where we can provide them more than
                    just product at a price. We find those customers, literally,
                    in every segment that we do business in and we'll continue
                    to keep working on them.

D. Yost        And let me add a thought here too, which is again, even though
                    our financial model is a little bit more aggressive than,
                    say, the IMS statistics, which is, as they've mentioned, we
                    feel are possibly on the conservative side. Our model works
                    at a lot lower level of growth than 20%. You know that mid-
                    teen level allows us to deliver ongoing strong financial
                    results.

R. Louis       Thank you very much.

D. Yost        You bet.

Moderator      And for our next question we will go to the line of John Green
                    with Dresner, Klineworth, Washerstein. Go ahead, please.

J. Green       Thanks. I was wondering if you guys could give us your view of
                    the pharmacist shortage sort of across your various customer
                    bases, institutional, retail, and independent? And then sort
                    of your assessment of your relative strengths and
                    capabilities in helping each of those segments deal with
                    that shortage.

D. Yost        John, I'll take a stab at it. I'm not sure I'm totally qualified
                    to respond, but that's


                                                               AMERISOURCE CORP.

                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 41

               never stopped me before. You know, I would say that the
               pharmacist shortage is probably hitting the largest chains the
               hardest. They look for a large number of pharmacists, the working
               conditions there are not always perceived as as pleasant as in
               some of the smaller chains and the independents and the like. I
               think that to the extent that there is a pharmacist shortage, I
               think it will result in the independents and the small chains
               continuing to gain momentum and strength.

     This year the number of independents went up about one percent, you know,
               and a couple of hundred new pharmacies opened. I think that is in
               part a reaction to the pharmacist shortage. The idea being there
               is more opportunity, I might as well just hang up a shingle, if
               I'm going to have to work long hours and get the full rewards for
               it.

     So I think what's going to emerge and the opportunities that are going to
               emerge are more systems to make the pharmacist a lot more
               productive. Clearly, our Autonomics is a step in that direction.
               We also have some opportunities, we think, with our packaging
               operation where we can take the pharmaceutical pills, the
               pharmaceuticals in bulk, and package them in unit of use, unit
               dose, and the likes of the pharmacist does not have to


                                                               AMERISOURCE CORP.

                    spend time counting out pills, pouring, licking and
                    sticking, as they say. So I think it's going to represent an
                    opportunity as we go forward for companies like AmeriSource.

J. Green       Great. What do you think about it on the institutional side? Do
                    you think the shortage is hitting there and is there
                    anything you can do to help out in that area?

D. Yost        You know the hospitals also have had some demands. As a general
                    rule, they do not have the same kind of problems because
                    many of the people who go to the hospital pharmacists are
                    attracted to the very clinical setting that occurs there,
                    where they have the opportunity to "practice" their
                    profession more.

               We do have a number of productivity initiatives launched for the
                    hospitals, as well, so that the pharmacist can spend more
                    time up on the floor and not spend time worrying about their
                    inventory.

J. Green       Okay. Great. Thanks a lot.

D. Yost        You bet.

Moderator      And next we will go to the line of Andy Speller, and Andy Speller
                    is with AG Edwards. Go ahead, please.

A. Speller     Good morning, guys. I just wanted to get some more color around
                    the FTC issues. Can you give a comment as to what they're
                    looking at? Are there going to have to be any divestitures
                    in terms of distribution centers or customer areas or
                    anything like that?

D. Yost        Andy, it's Dave. I'm not sure we know what they're looking at. We
                    don't have any insight to that. I would be very surprised if
                    any divestitures or the like were called for, Andy. In this
                    kind of a business, it just does not lend itself to that
                    kind of thing. It's not necessarily just the distribution
                    centers you've got, but rather the customers and the systems
                    and the like. So I would be very surprised to hear about any
                    divestiture request.

A. Speller     So would that mean if whatever their second request issues
                    weren't satisfied by your response, then it would either be
                    termination of the merger or there would be no way to get
                    over their concerns? I'm just trying to reconcile what
                    they're trying to get at.


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 44

D. Yost        Well, Andy, the truth of the matter is we don't know what they're
                    trying to get at or where they will come out. If they had
                    some concerns, we would certainly entertain them and see if
                    we could give them some comfort on that. So we're certainly
                    not ruling out anything as we go forward, but it's important
                    to know we have not heard from them yet and we probably will
                    not hear from them for some time, we think.

A. Speller     Okay. If I could just get another follow up in. In terms of how
                    are you positioned with your current distribution network?
                    If this merger doesn't go through, what sort of investments
                    do you have to make in the long term in terms of keeping
                    your customer base and moving forward if the merger doesn't
                    happen to go through?

K. Hilzinger   Andy, it's Kurt. You know, prior to the agreement with Bergen,
                    AmeriSource had just completed its own distribution network
                    study. So we had gone through, in a very systematic fashion,
                    pinpointed where we wanted to make additional investments in
                    our network, which included a handful of build outs and a
                    handful of consolidations so that we were properly fitted
                    to, one, our existing account base, and two, what we thought
                    were going to


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 45

                    be attractive market opportunities down the road. So that
                    was for the physical plant.

               In addition to that, you had heard us talk in the past about
                    Warehouse Management System, which is, basically, an
                    automation-enabling technology. It goes in the warehouse,
                    makes our warehouses basically a paperless environment. So
                    that was on the boards as well. Frankly, ..., in fact, the
                    technology offering that's available to the combined network
                    for AmeriSource Bergen, but on a stand-alone basis, you
                    know, we've got those plans in place and we're ready to
                    execute on those if for some reason the FTC doesn't see the
                    world our way. But again, that's not what we're anticipating
                    at this point.

A. Speller     Could you quantify the dollars there?

K. Hilzinger   I think we could be looking at facility builds, you know there
                    could be three to four new facilities that could go up in
                    the AmeriSource network in the next three to four years. You
                    know, you're talking anywhere between $10 and $20 million
                    for a facility, depending on whether you own the land and
                    the building. If you throw the land and the building in,
                    you're closer to $20 million. If you do not and you're
                    leasing a facility, you're down at the


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 46

                    $10 to $12, $13 million range. And we're talking about,
                    these are large-scale, highly automated facilities, 200,000
                    to 250,000 square feet from a footprint standpoint.

A. Speller     Okay. Thanks a lot. I appreciate the color there.

K. Hilzinger   You bet.

Moderator      And next we have in queue a question from the line of Christopher
                    McFadden with Goldman Sachs. Go ahead, please.

C. McFadden    Thanks. Good morning, everyone.

D. Yost        Good morning, Chris.

C. McFadden    A couple of questions if I might? First of all, could you talk
                    about the Health Nexus expenses this quarter again, some
                    acceleration over the previous. What you think we'll see or
                    should anticipate as we complete this calendar year. And
                    what is your commitment to Health Nexus and its funding
                    requirements looking out into calendar '02 and beyond? Also,
                    I was hoping you could update us on a trend at the VA and
                    how additive the VA


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 47

                    was to the strong institutional growth in the quarter?
                    Thanks.

D. Yost        First let me talk about Health Nexus, Chris. As we look out over
                    the next couple of quarters, our September and our December
                    quarter, I think it's reasonable to expect that Health Nexus
                    could be a similar amount to where they are now. They're
                    going to market with a couple of new products very soon. We
                    look for them to be cash neutral in two more quarters or so.
                    So the ramp up has come from the development cost. It's
                    primarily people. We spend a lot of time watching those
                    expenses, but I think they've got another couple of quarters
                    to go before they turn the corner. They're signing up
                    customers as we speak so we're optimistic that they'll meet
                    their plan.

          The VA continues to be a strong performer. They're growing similarly
                    to what our total business is and we continue to be happy
                    with that account.

C. McFadden    Dave, if they don't hit their internal targets for cash flow
                    neutrality, will these consolidated costs to your P&L
                    continue to move into '02? Should that be our expectation?


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 48

D. Yost        I would expect to see something there, Chris, at least for the
                    first quarter of '02 for us.

C. McFadden    Very good. Thank you.

Moderator      Then next we go to the line of Larry Marsch with Lehman Brothers.
                    Go ahead, please.

L. Marsch      Yes. Good morning, everyone. Just maybe a point of clarification
                    to the extent you can comment. I know in your press release
                    you suggest you anticipate completing the merger still by
                    the end of August, which you had said is consistent with
                    what you said in the past. Wouldn't that, by definition,
                    mean that you're going to declare certification within the
                    next week?

D. Yost        It would.

L. Marsch      So that would be the definition of shortly.

D. Yost        That would be a good definition of shortly.


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 49

L. Marsch      Okay. And just to back up your commentary about some feedback
                    that your information request was submitted earlier than,
                    kind of, the norm. Do you have any general comment about
                    what the norm usually is and how much quicker you were
                    versus that?

D. Yost        The only thing I can tell you, Larry, is what we've heard from
                    some of our attorneys, and they say that in a transaction
                    this size, not unusual to take ten/twelve weeks, you know,
                    something like that to respond to the FTC request. So that's
                    all I've got to go on, but we were very diligent in moving
                    forward to getting the information pulled together.

L. Marsch      Okay. Maybe as a follow up, in terms of bad debt expense.
                    Obviously, a smaller customer, Horizon, has declared Chapter
                    11 and named you as a creditor. What is the extent of your
                    exposure there and do you feel like you've already had some
                    reserving against that?

J. James       We feel our exposure is pretty limited there. We've been selling
                    them on a secured basis and we feel we've got strong
                    security there. So we think we're in pretty good shape.


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 50

L. Marsch      All right. So we would not anticipate any charge associated with
                    that?

J. James       That's our expectation, again, based on where we are in terms of
                    having a secured position.

L. Marsch      Great. Okay. And maybe a quick follow up to, I think, Chris's
                    question on Health Nexus, which is, do we have any
                    confidence that these expenses may not continue to tick up a
                    little bit before they round the bend? And how much control
                    do you have as a partner in this process to make sure that
                    doesn't happen?

D. Yost        I think we've got good cost controls in place, Larry. Being
                    involved with Health Nexus is a little unusual because we
                    are a partner, you know, we don't control it. Whereas Kurt
                    runs a pretty tight ship on everybody and keeps them under
                    their thumb, and in this case we've got a couple of
                    partners. But I will tell you that they will continue to
                    demonstrate good fiscal responsibility, and I remain
                    confident that they are going to be able to deliver value to
                    the marketplace and get paid for it probably by the end of
                    this calendar year.

L. Marsch      Okay.  Great.  That's all I had.  Thanks.

D. Yost        Thank you.

J. James       Thank you, Larry.

Moderator      And next we go to the line of Lynn Yaffi with Bank of America. Go
                    ahead, please.

L. Yaffi       Hi. If you've answered these, please feel free to skip them and
                    I'll listen on the replay. I missed part of the beginning. I
                    was just wondering if you could go through and break down
                    further the sales, institutional versus retail in terms of
                    hospital versus other and chain versus independents? And
                    secondly, what was the Health Nexus loss in the quarter? And
                    the final question is did you go through the ending debt
                    average debt numbers and the average interest rate?

J. James        Lynn, this is Jay. We did go through all of that. It's on the
                    replay, but I'd be happy to give it to you separately if you
                    want to give me a call after this.

L. Yaffi        That's fine.  Okay.  Thanks.

D. Yost         You bet.

Moderator       And next we go to the line of David Risenger. Please state your
                    firm followed by your question.

D. Risenger     Yes.  Merrill Lynch.  Congrats on a strong quarter.

D. Yost         Thank you.

D. Risenger     Would you please just give us a sense for merger document
                    filing? Is that something that you can comment on and just
                    what type of timing we should expect looking forward?

D. Yost         Are you talking, David, about the S-4?

D. Risenger     Yes.

D. Yost         I would say shortly you could expect that to be cleared. I would
                    say shortly.


                                                               AMERISOURCE CORP.

                                                                         Page 53


D. Risenger     And then the time line from when you file it, could you just
                    walk us through that?

D. Yost         You know, it has been filed, David. It hasn't been cleared yet.
                    There is a series of iterations where the SEC comes back and
                    has comments and you respond to it. We're in the process of
                    clearing those. After the SEC signs off on it, then you're
                    free to go out to the shareholders, and, I think, the
                    statutory requirements or regulatory requirements are simply
                    in the neighborhood that after the mailing you have to give
                    your shareholders 21 days in which to respond. That is, you
                    cannot schedule a meeting prior to 21 days from when they
                    get notice. So that kind of dovetails with the end of August
                    as well. That's why we're confident that we can close this
                    transaction by that time frame.

D. Risenger     That's great.  Thanks very much.

D. Yost         You bet.

Moderator       Our next question will be from the line of Lori Grumley with
                    John Hancock Advisors. Go ahead.

L. Grumley      Hi. Lori Grumley at John Hancock. My question's been asked and
                    answered. Thank you.

D. Yost         Thank you, Lori.

J. James        Good to hear from you, Lori.

Moderator       And next we'll go to the line of Bruce Babcock. Mr. Babcock
                    with Seabrook Capital. Please go ahead.

L. Farron       This is actually Laura Farron for Bruce Babcock. When we spoke
                    to you earlier in the quarter, you mentioned that you were
                    going to have a meeting after the close of the merger. Is
                    that still the plan?

D. Yost         Yes. We do plan it. We have not scheduled that of yet, but our
                    intent is to have a meeting.

L. Farron       Okay.  Thank you.

D. Yost         You bet.



                                                               AMERISOURCE CORP.

Moderator       And next we go to the line of Leo Murphy with Pioneer
                    Investment Management. Go ahead, please.

L. Murphy       Good morning.  I guess it's good afternoon.

D. Yost         That's right, Leo.

L. Murphy       It just keeps rolling along. I was going to hold them, but I
                    guess I'll do what everybody else does. I'll give you all of
                    the questions. I'm trying to understand, there was a comment
                    regarding the inventories by year end. Did I hear correctly
                    that the inventory levels will be at a point where you will
                    have basically reduced the current number by about $2 to
                    $300 million by the end of the year, in other words, this
                    quarter? Did I hear that correctly?

K. Hilzinger    We didn't quantify the number, but we do expect to reduce
                    inventories from current levels by the end of September.

L. Murphy       But if I heard you correctly, taking $50 to $100 million, in a
                    sense ending the year at $50 to $100 on that operating cash
                    flow basis would tend to imply


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 56

                    reducing that by about $300 million. Am I in the right
                    church? I just want to get a feel for it.

K. Hilzinger    I think you're in the right church.

L. Murphy       The other question I had, I have two other questions. Comment if
                    you would on the volume of scrips at the retail side. We've
                    heard a lot about the shortage of pharmacists and so on, but
                    when I saw scrips a couple of weeks ago, in terms of new
                    scrip volume, go to a zero plus one percent, it's kind of an
                    eye opener in a sense. I'm trying to understand why you
                    think that's happening. And I have one other question.

D. Yost         You know, Leo, I don't know. To be brutally honest, this is the
                    kind...probably should. I look more at volume so I don't
                    know. I will tell you it surprises me, but I don't know the
                    answer to that.

L.Murphy        I'm especially surprised, I mean the refills are running 4% or
                    5%, but new scrips, scrips for new drugs are running at
                    zero. And your industry is pumping out high, double-digit
                    numbers so I'm scratching my head.


                                                               AMERISOURCE CORP.
                                                        Host: Michael Kilpatrick
                                                    July 25, 2001/10:00 a.m. CDT
                                                                         Page 57

                The last question. You talked about your service you're
                   developing to provide to the pharmacist to make his life
                   somewhat more pleasant in terms of cutting down his time. Is
                   that a natural fit with what Bergen is attempting to do with
                   the remote scrip fills in the sense of having this central
                   filled?

D. Yost         It is, Leo. In fact, it's a great opportunity for synergies, I
                   think, because of the development costs involved in both. At
                   this point, from what I know about the Bergen system, which
                   is basically public information, they're going down a very
                   similar path to what we are. So we think having these two
                   programs together will decrease our development cost and it's
                   a good example of the kind of synergies that we can have
                   together.

L. Murphy       I appreciate it.  Thank you.

D. Yost         You bet.

M. Kilpatrick   This is Mike.  We'll take one more call.

Moderator       That will come from the line of Wayne Cooperman. Please state
                    your firm followed by your question.


                                                               AMERISOURCE CORP.

                                                                         Page 58

W. Cooperman    Hi.  Cobalt Capital. I think you might have answered this. But
                    does the equity in that loss, are you projecting that to
                    stay at this level or decline going forward and is that in
                    the estimates that are out there?

K. Hilzinger    Let me clarify that.  You are asking whether the...

W. Cooperman    You lost $2 million this quarter in your investment. Are you
                    projecting the losses to increase or decrease, and when you
                    give a guidance, I mean, are you factoring in this loss or
                    do you consider that a non-operating number?

D. Yost         We're expecting those losses to consider at about that rate for
                    the next couple of quarters.

W. Cooperman    And that's in the guidance?

D. Yost         Yes.

W. Cooperman    So the year after you'll get a pick up as those losses decline?


                                                               AMERISOURCE CORP.

                                                                         Page 59

J. James        Yes.

D. Yost         That would be our hope.

J. James        Let me clarify one thing you said. We don't have it in
                    operating. It's actually below the operating income line.

W. Cooperman    Right.

J. James        So it's not in operating expense.

W. Cooperman    No. But I guess on the EPS, that's factored into your
                    EPS?

J.James         It is in EPS, yes, and net income.

W. Cooperman    All right.  Thanks.

D. Yost         Okay.

M. Kilpatrick   Well, I want to thank everybody for joining us on the call
                    today. For those of you who are interested in hearing more
                    about AmeriSource's story, we'll be presenting at three
                    investor conferences during the coming quarter, and those
                    are in New York with Bear Stearns on September 13th, with
                    Merrill Lynch in London on September 25th, and in
                    Nashville we'll be there the first part of October with
                    Raymond James.

                With that I'd like to turn it over to Dave for some final
                    comments.

D. Yost         I just want to thank you all for joining us today. We're very
                      excited about our quarter. We're very excited and
                      enthusiastic about our future. We think we have good
                      revenue momentum, good expense control, good control of
                      our assets in a soild and growing industry. We're on our
                      way to complete an outstanding merger with an outstanding
                      merger with an outstanding company. We're very focused on
                      our business and we look forward to visiting you next
                      quarter. Thank you very much.
