               AmerisourceBergen Reviews Growth Opportunities and
                  Strategy at Investor Meeting in New York City

    Company Gives Update on Pharmaceutical Services Industry and Integration
                                    Progress

VALLEY FORGE, PA, December 5, 2002 -- AmerisourceBergen (NYSE:ABC), the largest
pharmaceutical services company in the United States dedicated solely to the
pharmaceutical supply chain, held an investor meeting in New York City today to
give an update on its future plans.

     Speaking at today's meeting, the Company's Chief Executive Officer R. David
Yost said, "We expect to grow our company by remaining focused on and enhancing
our position in the pharmaceutical supply channel. By harnessing the full array
of capabilities and expertise within AmerisourceBergen, we plan to bring new and
innovative value-added services to manufacturers and healthcare providers along
the channel. We remain focused on our integration efforts, and we are confident
that we will continue to meet our long term goals."

     The Company expressed confidence in
 its pharmaceutical distribution
business and believes that the industry's fundamental growth drivers remain
strong. "We are committed to pharmaceutical distribution, and we plan to
increase our capabilities throughout the channel in areas such as specialty
pharmaceuticals, patient safety, and pharmacy automation," continued Yost.

     "We also remain confident in our ability to achieve our targeted annual
cost saving synergies of $150 million by the end of fiscal year 2004, followed
by additional synergy capture through the completion of our distribution
network," remarked Yost. The Company previously announced that it would
consolidate a total of 27 of its original 51 facilities, build six new
distribution centers, and expand seven existing facilities. Seven consolidations
were completed in fiscal year 2002, and six larger distribution centers will be
consolidated in fiscal year 2003. The completed distribution network will
consist of 29 facilities located throughout the United States, and one facility
in Puerto Rico for a total of 30.

     "We are pleased to announce that we have broken ground on two of our new,
state of the art distribution facilities, one in Columbus, Ohio, and one in
Sacramento, California," said Kurt J. Hilzinger, AmerisourceBergen President and
Chief Operating Officer. "These two new distribution centers will be excellent
examples of what we envision for our future distribution network--highly
automated, bar code enabled, strategically located facilities, with a footprint
of 300,000 square feet each and unparalleled operating efficiency." The Company
is actively pursuing the acquisition of land for the remaining four new
distribution centers. The new facilities become operational approximately 24
months after land is acquired.

     "We also have made significant progress with the first of two planned
facility expansions that will be completed in fiscal year 2003. The expansion of
our Boston, Massachusetts distribution center is expected to be completed by the
end of the current calendar year," continued Hilzinger. "These facility
improvements will enhance our presence in each market and will enable us to
bring even greater efficiencies and added value to our customers."

     Looking ahead, the Company continues to see significant growth
opportunities across its businesses. "Through our focus on the pharmaceutical
channel, we continue to expect to drive strong performance in fiscal year 2003,"
said Michael D. DiCandilo, AmerisourceBergen Senior Vice President and Chief
Financial Officer. "In our December quarter, we see operating revenue growth of
approximately 13 percent and earnings per share growth of 20 percent, excluding
special charges. For the fiscal year 2003, we continue to expect operating
revenue growth in line with projected market growth, a return on committed
capital of more than 20 percent, and earnings per share growth, excluding
special charges, of 20 percent.

     "Our long-term goals remain to grow revenue with the market, consistently
achieve a return on committed capital of greater than 20 percent, and grow
earnings per share at 20 percent or more, excluding special charges."

     A rebroadcast of today's investor meeting is available beginning at 3:30 pm
Eastern Time today on the Investor Relations page of the Company's website,
www.amerisourcebergen.com. The replay of the webcast will be available for 30
days.
