                          AMERISOURCE REPORTS RECORD
                REVENUES AND EARNINGS FOR FISCAL THIRD QUARTER

 Operating Revenue Up Over 20 Percent, Net Income Up 25 Percent, EPS Hits $.57

VALLEY FORGE, PA, JULY 25, 2001 -- AmeriSource Health Corporation (NYSE:AAS)
today reported record results for its fiscal third quarter and nine months ended
June 30, 2001.  Operating revenue increased more than 20 percent in the third
quarter to a record $3.5 billion compared to $2.9 billion for the same period
last year. Net income for the quarter was up 25 percent to $31.5 million, also a
third-quarter record. Net income for same quarter last year was $25.1 million,
which included the positive after tax impact of $0.7 million for the reversal of
restructuring reserves.  Fiscal third quarter 2001 earnings per diluted share
were $.57 compared to $.48 per diluted share in the prior year.  Without the
restructuring reversal last year, earnings per diluted share for the third
quarter of fiscal 2001 increased 21 percent over the previous year's $.47 per
diluted share.

     For the first nine months of fiscal 2001, operating revenue increased 20
percent to a record $10.3 billion compared to $8.6 billion in the prior year
period. In the nine-month period, net income increased 26 percent to $89.2
million from $71.0 million for the same period last year, and earnings per
diluted share were $1.64, 20 percent ahead of the $1.37 per diluted share earned
in the first nine months of the prior year. Excluding the restructuring reversal
in the third quarter of last year, net income and earnings per diluted share for
the fiscal 2001 nine-month period increased 27 percent and 21 percent,
respectively. The following discussions of the third quarter and nine months
results do not include the impact of the reversal of the restructuring reserve
in fiscal year 2000.

     R. David Yost, AmeriSource Chairman and Chief Executive Officer, said,
"This was another terrific, record-setting quarter and year-to-date performance
for


AmeriSource, with superb revenue growth, notably lower expenses, outstanding
return on committed capital, and record earnings per share for a June quarter.
Each region and customer group contributed to revenue growth that was well ahead
of our 15 percent long-range goal, reflecting the dedication and strong efforts
of our associates at all levels. Total operating expenses as a percentage of
operating revenue were again below our 2.50 percent goal for the year, and ROCC
increased to 26.4 percent. Earnings per share continued to show strong year-
over-year growth in line with our long-term goal of 20 percent.

     "Our continuing solid performance is anchored in our ability to grow our
current account base and capture new business, while achieving our profitability
goals.  It also reflects the strength of the pharmaceuticals marketplace, where
the favorable demographics of an aging U.S. population continue to drive growth
more than general economic conditions.  Overall pharmaceutical sales are
projected to increase at a compound annual growth rate of 13.8 percent over the
next five years, according to IMS Health, a leading healthcare data service.

     "As we have mentioned before, our exceptional customer service, executed at
the distribution center level, is the key to our strong revenue growth. We also
continued to deliver on productivity improvement, both through the
implementation of cost reduction programs and by holding down costs while
growing revenue."

     Commenting on specifics of the quarter, Kurt J. Hilzinger, AmeriSource
President and Chief Operating Officer, said, "Our Health Systems group, which
leads the acute-care market, continued to build revenue momentum this quarter,
as we experienced the full impact of the $500 million in annualized, incremental
business from Novation, a major hospital group purchasing organization.  The
fast-growing Alternate Site group added new accounts, large and small, to our
growing base.

     "Our Chain Drugstore and Independent Community Pharmacy customer groups
continued to contribute to our revenue growth for the quarter.  The strong
performance of new accounts, such as the recently signed Familymeds Group, Inc.,
a multi-channel pharmacy retailer which will deliver more than $200 million in
annualized revenue, continues to expand our chain drugstore business. Our
independent community pharmacy


customers are driving same store growth at a double-digit rate, and continue to
be an integral part of our business.

     "Our ongoing financial discipline and the centralization initiatives
completed last year continued to contribute to high levels of procurement
performance, expense control and capital productivity."

     For the third quarter of fiscal 2001, the Company's gross margin as a
percentage of operating revenue was 4.12 percent versus 4.44 percent in the
prior year.  This expected year-to-year decline in gross margin primarily
reflects a shift in customer mix and a competitive marketplace.  The Company's
customer mix in the current quarter was 54 percent institutional, which
encompasses Health Systems and Alternate Site customer groups, and 46 percent
retail, including Independent Community Pharmacies and Chain Drugstores. In the
same period last year, the customer mix was 51 percent institutional and 49
percent retail.

     Total operating expenses as a percentage of operating revenue declined 39
basis points to a record low 2.41 percent in the third quarter of fiscal 2001
from 2.80 percent a year ago.  For the comparable nine-month periods, the ratio
declined 28 basis points to a record 2.47 percent in fiscal 2001 from 2.75
percent last year.  This reduction, which was accomplished despite $0.9 million
in merger integration costs, was driven by the shift in customer mix,
efficiencies of scale, and cost reductions aided by the centralization efforts.

     The Company's operating income advanced 26 percent to $60.2 million in the
third quarter of fiscal year 2001 from $47.8 million for the same quarter last
year.  For the fiscal third quarter, operating margin as a percentage of
operating revenue, improved to 1.71 percent compared to 1.64 percent for the
prior year period.

     Interest expense was down 12 percent to $7.4 million, reflecting the net
impact of higher average levels of debt, more than offset by lower borrowing
spreads and rates, as well as the effect of the Company's $300 million of fixed-
rate convertible notes issued in mid-December of last year.

Merger Update

     AmeriSource continues to move forward under its agreement, announced March
19, 2001, to combine with Bergen Brunswig Corporation to create a new company,
called


AmerisourceBergen Corporation. It expects to complete the merger by the end of
August 2001, following shareholder votes and Federal Trade Commission review.

     In connection with the Federal Trade Commission's review of the merger,
AmeriSource expects to certify compliance with the Commission's request for
additional information shortly. While the Company has filed all documents and
information for this "second request," it has delayed certification at the
request of the FTC staff.  Certification starts the FTC's 30-day review period
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.  After the
review, the merger may proceed if there is no objection from the Commission.

     "We are continuing our integration planning activities, even as each
company remains focused on its business," said Mr. Yost.  "This combination of
two strong, service-oriented companies boosts our confidence that we can achieve
a long-term earnings per share growth objective of 20 percent for our
shareholders."

                              EARNINGS PER SHARE
                     (In thousands, except per share data)
                                  (unaudited)

Earnings per share is computed on the basis of the weighted average number of
shares of common stock outstanding during the periods presented. Earnings per
share-assuming dilution is computed on the basis of the weighted average number
of shares of common stock outstanding during the period plus the dilutive effect
of stock options. Additionally, the fiscal 2001 calculations consider the
convertible subordinated notes as if converted and, therefore, the effect of
interest expense related to those notes is added back to net income in
determining income available to common stockholders.
