AMERISOURCE-BERGEN CORPORATION
MERGER HOTLINE/E-MAIL Q & A

AS OF 05/14/01

QUESTION
- --------
Assuming the merger is approved by all parties, will the dollar amount
accumulated by the BBC Medical Plan be transferred to the new plan or will we
get to "start over" again accumulating towards the lifetime cap? For instance,
say that over the course of 8 years, BBC paid out $100,000.00 worth of medical
bills on an associate. With the new plan decided upon by the new corporation,
will that $100,000.00 come into play or will there be a beginning balance of $0?

ANSWER
- ------
This is one of a number of decisions that will have to be made about the new
company's health plans. The question of whether and when to merge or create new
health plans, will be determined through the integration analysis process. Until
then, we will not be able to answer your question.


QUESTION
- --------
How will severance packages be paid out? In a lump payment or weekly?

When it comes to the severance package that will be offered, will that come in a
lump sum or will it be split up? If it is to be split, how would it be done?

ANSWER
- ------
A decision has not been made as to how severance will be paid, e.g., lump sum
payment or bi-weekly payments. It is a decision that will be determined through
the integration analysis process.


QUESTION
- --------
Regarding personal days, you did not actually answer it through your last
update. Does AmeriSource offer 2 paid personal days to their employees? And how
differently are their sick days from ours? Can you explain?

ANSWER
- ------
AmeriSource has six standard holidays and three floating personal holidays.
AmeriSource has PTO, "Paid Time Off" of up to 48 hours per year, in lieu of sick
days. No decisions have been made as to the benefits that will be provided in
the new company. Decisions such as the number of holidays, vacation schedules,
sick pay, and other benefits will be determined through the integration analysis
process.


QUESTION
- --------
Does AmeriSource offer flex days?

ANSWER
- ------
Yes, AmeriSource does offer flex days.



QUESTION
- --------
Are consultants in place now, to help organize the new structure?

ANSWER
- ------
Yes. As part of our process for creating an orderly and smooth transition to
AmeriSource-Bergen Corporation, we have hired Deloitte Consulting. They will
assist us in the integration activities by helping to gather information,
analyze data, and develop action plans that will enable us to make sound
decisions as we bring Bergen Brunswig and AmeriSource together. Deloitte
Consulting will report to the combined management team who will lead the
integration. Deloitte was selected because of their extensive experience with
merger projects and their in-depth knowledge of the pharmaceutical and
healthcare supply chain. They have consulted on numerous merger integration
projects, many IT integrations, several pharmaceutical distribution supply chain
strategy activities, and a variety of supply chain projects. We will continue to
keep you informed as the structure, planning and activities of the integration
are established.


QUESTION
- --------
Are Inventory Clerk positions going to be eliminated? Does AmeriSource have
Inventory Clerks in their facilities?

ANSWER
- ------
No decisions have been made as to positions being eliminated. AmeriSource does
have Inventory Clerks in their facilities.


QUESTION
- --------
In a previous Q & A regarding stock options, you talked about the selling of
stock options. You cannot actually sell options can you?

ANSWER
- ------
Good catch. No, you cannot sell stock options. You "exercise" stock options,
which means that you buy the stock of the company at the price the option was
issued. Thereafter you are the owner of the shares. They are yours to hold or
sell at your sole discretion.


QUESTION
- --------
If the pending merger is approved and closes before December 31, will the ESPP
program continue until December 31? As I understand, when the merger is
consumated the purchase period will end and Bergen stock will be purchased and
converted to ABC stock. Let's say the merger is done in October. Will the ESPP
deductions continue with the purchase of ABC stock until the end of the year or
will the ESPP end as of the merger?

ANSWER
- ------
The purchase period is from July 1, 2001 through December 31, 2001. However, if
the pending merger between Bergen Brunswig and AmeriSource is approved and
closes prior to December 31, 2001, the purchase period will end on the day
before the merger closing date. Purchases of Bergen stock would be made and
would then automatically be converted into AmeriSource-Bergen stock on the
transaction closing date.



QUESTION
- --------
What's going on with our REWARD checks.

ANSWER
- ------
REWARD checks are distributed approximately 6 to 8 weeks following the end of a
fiscal quarter (December, March, June, September). REWARD checks, where earned,
will be distributed no later than May 25, 2001 which would be 8 weeks after the
end of the second fiscal quarter.
