                                PROXY STATEMENT
                            ------------------------

GENERAL INFORMATION

     This proxy statement is furnished by the Board of Directors of
AmerisourceBergen Corporation (the "Company") in connection with its
solicitation of proxies for use at the Annual Meeting of Stockholders to be held
February 27, 2002 and at any adjournments thereof (the "Annual Meeting"). The
Company's annual report to stockholders, including financial statements,
accompanies this notice and proxy statement, but is not incorporated as part of
the proxy statement and is not to be regarded as part of the proxy solicitation
material. The proxy and this proxy statement are being mailed to stockholders on
or about January 30, 2002.

     Proxies are solicited by the Board of Directors of the Company in order to
provide every stockholder an opportunity to vote on all matters scheduled to
come before the meeting, whether or not he or she attends the meeting in person.
When the enclosed proxy card is returned properly signed, the shares represented
thereby will be voted by the proxy holders named on the proxy card in accordance
with the stockholder's directions. You are urged to specify your choices by
marking the appropriate boxes on the enclosed proxy card. If the proxy is signed
and returned without specifying choices, the shares will be voted as recommended
by the Board of Directors.

     Solicitation of proxies is made on behalf of the Board of Directors of the
Company, and the cost of preparing, assembling and mailing the notice of Annual
Meeting, proxy statement, and form of proxy will be borne by the Company. In
addition to the use of the mail, proxies may be solicited by directors, officers
and regular employees of the Company, without additional compensation, in person
or by telephone or other electronic means. The Company will reimburse brokerage
houses and other nominees for their expenses in forwarding proxy material to
beneficial owners of the Company's stock.

     This is the Company's first proxy statement and annual meeting of
stockholders since the completion of the merger (the "Merger") of AmeriSource
Health Corporation, a Delaware corporation ("AmeriSource"), and Bergen Brunswig
Corporation, a New Jersey corporation ("Bergen"), on August 29, 2001 (the
"Merger Date"). Thus, certain information in this proxy statement necessarily
pertains to AmeriSource and Bergen prior to the Merger.

REVOCABILITY OF PROXY

     Execution of the enclosed proxy will not affect your right to attend the
Annual Meeting and vote in person. If you do attend, you may vote by ballot at
the meeting, thereby effectively canceling any proxies previously given. In
addition, a stockholder giving a proxy may revoke it at any time before it is
voted at the meeting by filing with the Secretary of the Company an instrument
revoking it, or by filing with the Company a duly executed proxy bearing a later
date.

VOTING AT THE ANNUAL MEETING

     Only the holders of record of shares of Common Stock, par value $0.01 per
share (the "Common Stock"), of the Company at the close of business on January
14, 2002 are entitled to receive notice of and to vote at the Annual Meeting.
Each holder of Common Stock entitled to vote will have the right to one vote for
each share held on all matters to come before the meeting. On January 14, 2002,
there were 103,962,200 shares of Common Stock issued and outstanding.

                                        1


     The holders of a majority of the shares of Common Stock entitled to vote
must be present in person or by proxy at the Annual Meeting to constitute a
quorum for the purpose of transacting business at the meeting. Except for the
election of directors, the affirmative vote of the holders of a majority of the
shares of Common Stock present in person or by proxy at the meeting and entitled
to vote on a proposal is required to ratify and approve the proposal.
Abstentions are counted in tabulations of the votes cast by stockholders on the
proposals and will have the effect of a negative vote. Broker non-votes will not
be counted for purposes of determining whether any proposal has been approved.
Directors are elected by a plurality of the votes present or represented by
proxy at the meeting and entitled to vote on the election of directors. Because
directors are elected by a plurality of votes, abstentions and broker non-votes
will not affect their election.

                                   PROPOSAL 1

                             ELECTION OF DIRECTORS

     The Company's Board of Directors currently consists of ten directors,
divided into three classes: Class I, Class II and Class III, each class being as
nearly equal in number as possible. Pursuant to the agreement governing the
Merger, AmeriSource designated four members of the Board of Directors and Bergen
designated four members of the Board of Directors, and since the Merger, the
Board has appointed two additional directors. The directors of each class serve
terms of three years. The term of office of one class of directors expires each
year in rotation so that one class is elected at each annual meeting of
stockholders for a three year term. The term of the four Class I directors, Dr.
Jane E. Henney and Messrs. Rodney H. Brady, Charles H. Cotros and R. David Yost,
will expire at the Annual Meeting. The other six directors will remain in office
for the remainder of their respective terms, as indicated below.

     At the Annual Meeting four Class I directors are to be elected. Each of the
director nominees is currently a director of the Company. Each nominee for
director has consented to his or her nomination and, so far as the Board of
Directors and management are aware, will serve as a director if elected.
However, if any of the nominees should become unavailable prior to the election,
the shares represented by proxies may be voted for the election of such other
persons as the Board of Directors may recommend, unless the Board of Directors
chooses to reduce the number of directors to be elected. Unless otherwise
specified by the stockholders, it is intended that the shares represented by
proxies will be voted for the four nominees for director listed below. There is
no arrangement or understanding between any director or nominee for director and
any other person(s) pursuant to which he or she was or is to be selected as a
director or nominee.

COMMITTEES OF THE BOARD OF DIRECTORS

     The standing committees of the Board of Directors are the Audit and
Corporate Responsibility Committee, the Compensation and Succession Planning
Committee, the Executive and Finance Committee and the Governance and Investment
Committee. Because the Company was formed on August 29, 2001 and its fiscal year
ended on September 30, 2001, there were very few committee meetings during
fiscal year 2001.

     The Audit and Corporate Responsibility Committee (i) advises the Board of
Directors on the scope of the annual audit by the independent auditors for the
Company, the Company's internal audit program and

located. A full description of the Audit and Corporate Responsibility
Committee's primary responsibilities, operating principles, and relationship
with internal and external auditors is contained in the Audit and Corporate
Responsibility Committee Charter, which is attached to this proxy statement as
Appendix A. The Audit and Corporate Responsibility Committee held one meeting
during fiscal year 2001. The Chairman of the Audit and Corporate Responsibility
Committee is Mr. Hagenlocker and its other members are Messrs. Brady, Gozon and
Rodgers.

     The Compensation and Succession Planning Committee (i) reviews annually and
approves the Company's executive compensation strategy to ensure that management

Succession Planning Committee the factors on which compensation for the Chief
Executive Officer and other members of senior management was based, including

alignment with the Company's overall performance objectives, and (vii) proposes
stock option plans to stockholders that are consistent with stockholder
interests in providing a competitive incentive plan for key associates,

their effectiveness. The Compensation and Succession Planning Committee held one
meeting during fiscal year 2001. The Chairman of the Compensation and Succession
Planning Committee is Mr. Mellor and its other members are Messrs. Gozon,
Rodgers and Wilson.

     The Executive and Finance Committee, except as limited by Delaware law and
the Company's Bylaws, (i) has all of the powers and exercises all of the
authority of the Board of Directors between the meetings of the Board and while
the Board is not in session, (ii) reviews the asset and liability structure of
the Company, and considers its funding and capital needs, and (iii) reviews
reports on the progress of investment activities and strategies developed to
meet changing economic and market conditions. The Executive and Finance
Committee did not meet during fiscal year 2001. The Chairman of the Executive
and Finance Committee is Mr. Yost and its other members are Messrs. Martini,
Mellor and Wilson.

     The Governance and Investment Committee (i) identifies and evaluates
qualified candidates to serve as Directors of the Company, including both at
annual meetings of stockholders and in connection with filling any vacancies
which may occur, (ii) makes recommendations to the Board of Directors concerning
such candidates, (iii) assesses the performance of the Board of Directors, and
(iv) oversees the administration of the Company's employee benefit plans and
investment decisions relating to the retirement plans. Such Committee also has
the responsibility for evaluating and advising the Board on the Company's
approach to corporate governance. The Governance and Investment Committee did
not meet during fiscal year 2001. The Chairman of the Governance and Investment
Committee is Mr. Brady and its other members are Messrs. Hagenlocker, Martini
and Wilson.

COMPENSATION OF DIRECTORS

     Directors who are full-time employees of the Company receive no additional
compensation for services as a director. Each non-employee director of the
Company is paid an annual fee of $50,000 for services as a
                                        5


director of the Company, a fee of $2,000 for attendance in person at each
meeting of the Board of Directors and a fee of $1,000 for attendance in person
at each committee meeting. The Chairman of the Board receives a fee of $4,000
for attendance in person at each meeting of the Board of Directors and committee
chairpersons receive a fee of $2,000 for attendance in person at each committee
meeting. Each non-employee director receives 50% of the in-person meeting fee
for telephonic Board and committee meetings.

     The Company's directors are entitled to a one-time grant of restricted
stock having a value of $50,000 at the date of grant, which generally vests
three years from the date of grant. In addition, the Company's directors are
entitled to an annual grant of non-qualified stock options having a
Black-Scholes value of $100,000 and a strike price equal to the closing price of
shares on the day before the date of grant. Stock options will vest in equal
annual installments over the three-year period from the date of grant, subject
to continued service on the Board. Option grants will generally be effective as
of each Annual Meeting of Stockholders.

     The Company offers three deferred compensation or equity conversion
opportunities for non-employee directors:

  AmerisourceBergen Corporation 2001 Deferred Compensation Plan

     A director may elect to defer all or any part of the annual retainer
compensation and meeting fees received and have the deferred amount credited to
an account under the AmerisourceBergen Corporation 2001 Deferred Compensation
Plan ("Deferred Compensation Plan"). Deferred accounts will be credited with
interest at one percentage point higher than the prime rate as in effect from
time to time. Payment under the Deferred Compensation Plan will be made or
commence on the first day of the month after the non-employee director ceases
being a director of the Company. Alternatively, a director may elect to receive
a deferred benefit: (i) over annual periods ranging from three to fifteen years
and payable in quarterly installments; or (ii) in a single distribution. The
Company pays all costs and expenses incurred in the administration of the
Deferred Compensation Plan.

  AmerisourceBergen Corporation 2001 Non-Employee Directors' Restricted Stock
Plan

     A director may elect to forego 50% or more of the annual retainer
compensation received and in lieu thereof, provided the director does not elect
to have the foregone amount credited in the form of stock options under the
AmerisourceBergen Corporation 2001 Non-Employee Directors' Stock Option Plan,
receive a grant of restricted stock having a value equal to 125% of the amount
of compensation foregone. In most cases, all restrictions on the stock will
lapse three years from the grant date. A director who retires prior to three
years from the date of grant could receive a pro rata distribution of such stock
at the discretion of the Board. A director may also elect to defer the receipt
of shares subject to restrictions to a date certain or to death, disability or
termination of service by electing to defer the receipt of shares at least one
year in advance of the vesting date. In general, restricted stock granted will
be treated as granted in advance on or about the date of the Annual Meeting of
Stockholders, based on the closing price of Company stock on the immediately
preceding business day.

REPORT OF THE AUDIT AND CORPORATE RESPONSIBILITY COMMITTEE OF THE BOARD OF
DIRECTORS

     The Audit and Corporate Responsibility Committee (the "Audit Committee")
reviews the Company's financial reporting process on behalf of the Board. In
fulfilling its responsibilities, the Audit Committee reviewed and discussed the
audited financial statements contained in the Company's Annual Report on Form
10-K for the fiscal year ended September 30, 2001 with the Company's management,
including a discussion of the quality, not just the acceptability, of the
accounting principles, the reasonableness of significant judgments, and the
clarity of disclosures in the financial statements. Management has the primary
responsibility for the financial statements and the reporting process, including
the system of internal controls, and has represented to the Audit Committee that
such financial statements were prepared in accordance with generally accepted
accounting principles. The Audit Committee reviewed with the independent
auditors, who are responsible for expressing an opinion on the conformity of
those audited financial statements with accounting principles generally accepted
in the United States, their judgments as to the quality, not just the
acceptability, of the Company's accounting principles and such other matters as
are required to be discussed with the Audit Committee under generally accepted
auditing standards.

     The Audit Committee discussed with the independent auditors the matters
required to be discussed by Statement on Auditing Standards No. 61,
Communication with Audit Committees, as amended. In addition, the Audit
Committee has discussed with the independent auditors the auditors' independence
from the Company and its management, including the matters in the written
disclosures and letter which were received by the Audit Committee from the
independent auditors as required by Independence Standards Board Standard No. 1,
Independence Discussions with Audit Committees, as amended, and considered the
compatibility of non-audit services with the auditors' independence.

     Based on the reviews and discussions referred to above, the Audit Committee
recommended to the Board that the audited financial statements be included in
the Company's Annual Report on Form 10-K for the year ended September 30, 2001.

     During the fiscal year ended September 30, 2001, Ernst & Young LLP, the
Company's independent auditors, billed the Company the fees set forth below in

REPORT OF THE COMPENSATION AND SUCCESSION PLANNING COMMITTEE OF THE BOARD OF
DIRECTORS

     The role of the Compensation and Succession Planning Committee of the
Company (the "Compensation Committee") is to recommend, establish, oversee and
direct the Company's executive compensation policies and programs and to
recommend to the Board of Directors compensation for executive officers. In
carrying out this role, the Compensation Committee believes it is important to
align executive compensation with Company values and objectives, business
strategies, management initiatives, business financial performance and enhanced
stockholder value.

     The Compensation Committee is comprised of independent outside directors,
none of whom is or was an officer or employee of AmeriSource, Bergen, any of
their respective subsidiaries, or the Company. Certain compensation decisions,
such as stock option awards and executive bonus payments, were made for fiscal
year 2001 by each of the compensation committees of AmeriSource and Bergen.
Therefore, the members of the Compensation Committee are, in certain instances,
reporting on determinations and actions made by the prior compensation
committees. Periodically the Compensation Committee solicits and receives
recommendations and advice from independent third-party compensation
consultants.

  Compensation Philosophy

     The goals of the Company's compensation program are (i) to align individual
contributions with business objectives and performance, (ii) to enable the
Company to attract, retain and reward executive officers who contribute to the
long-term success of the Company, and (iii) to motivate those executives to
advance the interests of stockholders.

     The executive compensation programs both of AmeriSource and Bergen were
designed to attract and retain key executives with outstanding abilities and to
motivate them to perform to the full extent of their abilities. The Compensation
Committee believes that executives should have a greater portion of their
compensation at risk than other employees, and that executive compensation
should be tied directly to the performance of the business and be aligned with
benefits realized by the Company's stockholders.

  Components of Compensation

     Compensation for Company executives, in effect for applicable executives of
AmeriSource and Bergen during fiscal year 2001, consisted of both cash and
equity-based opportunities. The annual cash compensation consisted of (i) base
salary and (ii) an annual incentive opportunity. Equity-based opportunities are
provided on a long-term basis through the Company's stock option plans.

     The compensation consultants retained by the compensation committees of
AmeriSource and Bergen have advised that the salaries, when coupled with annual
incentive awards paid to the Company's Chief Executive Officer and other
executive officers, are consistent with competitive practices in the industry.
In making this determination, the consultants analyzed the compensation payable
at the pharmaceutical wholesale distribution companies included in the Peer
Group Index described in the discussion of Stockholder

                                        8


Return Performance below, and also relied upon survey data covering a broader
range of wholesale and distribution companies.

     The Company's Compensation Committee has reviewed the base salaries of
executive officers and has made adjustments that in its judgment are
appropriate. The Compensation Committee reviews executive officer salaries
annually and makes adjustments based on past performance, changed job duties,
scope and responsibilities, competitive pay data and expected future
contributions of each executive officer.

     The Compensation Committee also oversees the Company's annual incentive
payments to executive officers. Each year the Compensation Committee establishes
challenging objectives based on business prospects for that year. For Messrs.
Yost, Hilzinger, Dimick, Carpenter and Martini, and for the other senior members
of management, annual incentive opportunities are based on achieving both
current financial performance objectives and individual strategic and operating
objectives related to longer-term earnings, with greater weight given to the
current financial performance objectives. Following the end of each fiscal year,
the Compensation Committee reviews business results and the individual
performance of each executive officer and each senior member of management, and
determines and recommends to the Board of Directors annual incentive payments.
In fiscal year 2001, both AmeriSource and Bergen exceeded their financial
performance goals for earnings per share and return on committed capital.
Strategic and operating objectives were met by Messrs. Yost and Hilzinger for
AmeriSource and Messrs. Dimick, Carpenter and Martini for Bergen.

     AmeriSource's long-term, equity-based 1999 Stock Option Plan (the "1999
AmeriSource Plan") and Bergen's similar 1999 Management Stock Incentive Plan
(the "1999 Bergen Plan") were approved by their respective Boards of Directors
in December 1998 and September 1998, respectively, and by their stockholders in
March 1999 and April 1999, respectively. The Compensation Committee of each of
AmeriSource and Bergen administered the 1999 AmeriSource Plan and the 1999
Bergen Plan. The 1999 AmeriSource Plan consisted of non-qualified stock option
grants and the 1999 Bergen Plan consisted of both non-qualified and incentive
stock option grants. Options to purchase a total of 180,000 shares of Common
Stock were granted pursuant to the 1999 AmeriSource Plan to Messrs. Yost and
Hilzinger in fiscal year 2001, representing approximately 14% of the options
granted to AmeriSource's management. Options to purchase a total of 56,974
shares of Common Stock were granted pursuant to the 1999 Bergen Plan to Messrs.
Dimick, Carpenter and Martini in fiscal year 2001, representing approximately 9%
of the options granted to Bergen's management.

     AmeriSource's long-term, equity-based 2001 Stock Option Plan (the "2001
AmeriSource Plan") was approved by its Board of Directors in December 2000 and
by its stockholders in March 2001. The Compensation Committee of AmeriSource
administered the 2001 AmeriSource Plan. The 2001 AmeriSource Plan consisted of
non-qualified stock option grants. Options to purchase a total of 275,000 shares
of Common Stock were granted pursuant to the 2001 AmeriSource Plan to the
executive officers of AmerisourceBergen in fiscal year 2001, representing
approximately 15% of the options granted to AmerisourceBergen's management.

  Chief Executive Officer Compensation

     Each year that Mr. Yost was the Chief Executive Officer of AmeriSource, its
Compensation Committee and Mr. Yost agreed to multi-year objectives. With Mr.
Yost becoming the Chief Executive Officer of the Company, the Compensation
Committee of the Company will review the Chief Executive Officer's performance
against those objectives at year-end. This review includes a detailed analysis
of the short-and long-term financial results as well as progress toward the
Company's strategic objectives. In addition, the Compensation Committee
considers individual factors such as Mr. Yost's leadership ability, ability to
execute the business strategy and the Company's relationship with customers and
the investment community. Mr. Yost's salary has been determined based on data
received on the salaries of chief executive officers at

                                        9


companies included in the Peer Group Index as well as upon survey data obtained
from wholesale and distribution companies generally.

     Mr. Yost's annual incentive opportunity prior to the Merger was 120% of his
base salary, subject to certain adjustments based on his individual performance,
as determined by the Compensation Committee, and the performance of the Company.
Of this amount, 50% was based on the Company's achievement of earnings per share
("EPS") goals and 50% was based on goals relating to return on committed
capital. For fiscal year 2001, the Company exceeded its EPS goal and exceeded
the goal for return on committed capital. Based on the foregoing factors, Mr.
Yost's annual incentive payment was 114% of his base salary.

  Deductibility of Compensation

     Section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Code"), imposes a $1 million limit on the deductibility of compensation paid to
certain executive officers of public companies, unless the compensation meets
certain requirements for "performance-based" compensation. Non-performance-based
compensation paid to the Company's executive officers for fiscal year 2001
exceeded the $1 million limit per officer only by a modest amount for Mr. Yost
and the Compensation Committee has decided not to take any action at this time
to limit or restructure the elements of cash compensation payable to the
Company's executive officers.

     The Compensation Committee will continue to consider and evaluate all the
Company's compensation programs in light of Section 162(m) of the Code and
related regulations. However, the Company may pay compensation which is not
deductible in certain circumstances if sound business judgment so requires.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     No member of the Compensation Committee is a former or current officer or
employee of the Company, AmeriSource or Bergen or any of their respective
subsidiaries. To the Company's knowledge, there were no other relationships
involving members of the Compensation Committee requiring disclosure in this
section of this proxy statement.

                                   PROPOSAL 2

                 APPROVAL OF THE AMERISOURCEBERGEN CORPORATION
                       2002 EMPLOYEE STOCK PURCHASE PLAN

     On January 18, 2002, the Board of Directors of the Company authorized the
adoption of a new AmerisourceBergen Corporation 2002 Employee Stock Purchase
Plan (the "Plan"), which is attached to this proxy statement as Appendix B. So
that participants may enjoy certain tax advantages, the Plan is intended to meet
the requirements of Section 423 of the Code. Approval of the Plan by the
Company's stockholders is a condition to favorable tax treatment under Section
423.

     The purpose of the Plan is to encourage the purchase of Common Stock by the
Company's employees and the employees of the subsidiaries of the Company whose
participation is approved by the Board of Directors, to provide employees with a
personal stake in the Company and to help recruit and retain

                                        10


employees. The Board of Directors has designated AmeriSource, Bergen and their
subsidiaries as Participating Companies whose employees may become eligible to
participate in the Plan.

     Provided that the Company's adoption of the Plan is approved by the
Company's stockholders, it is anticipated that the first offering period under
the Plan will commence on a date following the Annual Meeting as determined by
the Compensation Committee, which will also serve as the Plan Administrator.

DESCRIPTION OF THE PLAN

     The Plan provides employees with the right to purchase shares of Common
Stock through payroll deduction. A total of 4,000,000 shares of Common Stock
will be available for purchase under the Plan, subject to adjustment in the
number and price of shares available for purchase if the number of outstanding
shares of Common Stock are increased or decreased through stock dividends,
recapitalizations, stock splits, reorganizations or similar changes.

  Eligibility and Participation

     Generally, an employee of a participating company is eligible to
participate in the Plan if the employee has completed 30 or more days of service
as of the start date of an offering period. If the Plan had been effective as of
December 31, 2001, approximately 12,000 employees, including the Company's
executive officers, would have been eligible to participate in the Plan.
Employees who, after purchasing shares of Common Stock under the Plan, would own
5% or more of the total combined voting power or value of all classes of the
equity securities of the Company or any subsidiary corporation are not eligible
to purchase additional shares under the Plan. In addition, the maximum fair
market value of Common Stock an eligible employee may purchase in a calendar
year is limited to $25,000.

     Shares of Common Stock will be available under the Plan during each
offering period. The offering periods will be semi-annual periods commencing on
dates determined from time to time by the Compensation Committee. Eligible
employees may elect to participate in the Plan before the start of an offering
period. Shares of Common Stock will be deemed to have been purchased on the last
day of the offering period. The purchase price per share will be 85 percent of
the lesser of the fair market value per share of Common Stock on the first day
of the offering period or the fair market value per share of Common Stock on the
last business day of the offering period.

     To become a participant in the Plan (for purposes of this Proposal 2, a
"Participant"), an eligible employee who wishes to participate in the Plan must
file an election form with the Plan Administrator or its designee at least 30
days before the beginning of an offering period. Each Participant will have
payroll deductions of any whole percentage up to 25% of his or her compensation
made on each regular payday during the time he or she is a Participant in the
Plan. All payroll deductions will be credited to the Participant's account under
the Plan.

  Termination of Participation

     A Participant may discontinue his or her participation in the Plan at any
time, but no other change can be made during an offering period. If a
Participant's employment terminates for any reason, all amounts credited to such
Participant's account will be returned to the Participant. A Participant who is
on an approved leave of absence will remain eligible to participate in the Plan
through the end of the offering that commenced prior to such leave, unless the
approved leave of absence ends and the Participant does not return to active
employment prior to the end of that offering.

                                        11


  Method of Share Purchase; Holding Period

     All funds held or received by the Company under the Plan may be used for
any corporate purpose until applied to the purchase of Common Stock or refunded
to employees and shall not be segregated from the Company's general assets.
Shares of Common Stock purchased under the Plan will be issued from the
Company's treasury shares or from authorized but unissued shares. The Company
will pay all fees and expenses incurred, excluding individual federal, state,
local or other taxes, in connection with the Plan.

     A participant may not dispose of any share of Common Stock purchased under
the Plan before the later of (i) the lapse of 18 months from the start date of
an offering period or (ii) the lapse of one year after the transfer of the share
to the participant.

  Federal Income Taxation

     The Plan is not qualified under Section 401(a) of the Code. The Company
generally will not be entitled to a deduction with respect to stock purchased
under the Plan, unless the stock is disposed of less than one year after it is
purchased by the employee, or less than two years after the start of the
offering period pursuant to which the stock was purchased.

     Generally, no tax consequences arise at the time the Participant purchases
shares of Common Stock under the Plan. In general, upon a disposition of shares,
the Participant will receive compensation taxable as ordinary income for the
taxable year in which the disposition occurs in an amount equal to the lesser of
the excess of the fair market over the purchase price value of the shares at the
beginning of the offering period or the excess over the purchase price of (i)
the amount actually received for the shares if sold or exchanged or (ii) the
fair market value of the shares on the date of any other termination of his or
her ownership (such as by gift). The amount of such ordinary income is then
added to the Participant's basis in his shares for purposes of determining
capital gain or loss. This tax treatment only applies if the Participant does
not dispose of the shares for at least one year after the date of purchase and
the Participant does not dispose of the shares for at least two years after the
beginning of the offering period pursuant to which the shares were purchased.

     If a Participant disposes of shares of Common Stock purchased under the
Plan before the holding period is satisfied, he or she will receive compensation
taxable as ordinary income in the amount of the difference between the amount
paid for the shares and the fair market value of the shares at the time of
purchase. If the shares are sold or exchanged, the amount of such ordinary
income is added to the Participant's basis in his shares for purposes of
determining capital gain or loss.

     If a Participant dies before disposing of the shares purchased under the
Plan, he or she will be deemed to have realized compensation income taxable as
ordinary income in the taxable year closing with his or her death in an amount
equal to the lesser of the excess of the fair market over the purchase price
value of the shares at the beginning of the offering period or the excess over
the purchase price of the fair market value of the shares on the date of death.
The Participant is deemed not to have realized any capital gain or loss because
of death.

  Amendment or Termination of the Plan

     The Board of Directors has the right to amend, modify or terminate the Plan
at any time without notice, provided that, upon any termination, all shares or
unapplied payroll deductions will be distributed to Participants, and provided
further, that no amendment will affect the right of a Participant to receive his
or her proportionate interest in the shares or unapplied payroll deductions.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE "FOR"
APPROVAL OF THE ADOPTION OF THE AMERISOURCEBERGEN CORPORATION 2002 EMPLOYEE
STOCK PURCHASE PLAN AS DESCRIBED IN THIS PROPOSAL 2.

(1) The options granted to Messrs. Yost and Hilzinger, unless otherwise noted,
    vest 25% one year after the date of grant and then 25% per year thereafter.
    The options granted to Messrs. Dimick, Carpenter and Martini, unless
    otherwise noted, generally vest 33 1/3% one year after the date of grant and
    then 33 1/3% per year thereafter.

(2) Pursuant to the Merger Agreement dated March 16, 2001, all options granted
    prior to February 15, 2001 became fully vested on August 28, 2001, but shall
    not become exercisable until August 29, 2002.

(3) All options granted on September 17, 2001 to Messrs. Yost, Hilzinger,
    Dimick, Carpenter and Martini vest 25% one year after the date of grant and
    then 25% per year thereafter.

(4) Present values were calculated using the Black-Scholes option valuation
    method. The actual value, if any, that an executive officer may receive is
    dependent on the excess of the stock price as of the date of exercise over
    the exercise price. Use of this model should not be viewed as a forecast of
    the future performance of the Company's stock price. The estimated grant
    date present value of the stock options ranged from $19.93 to $32.56 based
    on the following defined option terms and assumptions: (i) grant prices
    ranging from $33.608 to $64.02; (ii) exercise prices ranging from $33.608 to
    $64.02; (iii) expected life ranging from four to five years; (iv) risk-free
    interest rates ranging from 4.0% to 5.6%, which represents the yield on
    Treasury Bonds with maturity dates corresponding to that of the options; (v)
    a dividend yield of .2%, representing the stock's current yield; and (vi)
    stock price volatility rates ranging from .497 to .785.

PENSION PLANS

     AmeriSource and Bergen, each a wholly owned subsidiary of the Company,
continued to maintain separate retirement plans covering their respective
employees following the Merger. It is anticipated that these separate retirement
plans will be superseded by one or more integrated retirement plans of the
Company effective July 1, 2002.

     AMERISOURCE CORPORATION PARTICIPATING COMPANIES PENSION PLAN.   AmeriSource
maintains a qualified defined benefit pension plan providing pension benefit
coverage for employees of AmeriSource who meet the plan's eligibility
requirements. Employees first hired after September 14, 2001 are not eligible to
participate in the pension plan.

     Under AmeriSource's pension plan, the executive officers compensated by
AmeriSource are entitled to annual pension benefits at age 65 equal to the
number of years of credited service multiplied by 1% of average annual
compensation earned during the three consecutive years within the last ten years
of participation in the pension plan which yield the highest average.

     All pension plan costs are paid by AmeriSource and the pension plan and
benefits are funded on an actuarial basis. Compensation earned by executive
officers for purposes of the plan includes salaries and bonuses set forth in the
cash compensation table under "Summary Compensation Table" above, except that
compensation recognized under the plan may not exceed certain limits, as
required by the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), and the Code. For 2001, the compensation limit was $170,000.

     As of October 1, 2001, the years of credited service for each of the named
executive officers of the Company were as follows: R. David Yost -- 27.08 years
and Kurt J. Hilzinger -- 10.58 years.

     As required by ERISA and the Code, the pension plan limits the maximum
annual benefits payable at Social Security retirement age as a single life
annuity to the lesser of $90,000, with cost-of-living adjustments, or 100% of a
plan participant's average total taxable earnings during his highest three
consecutive calendar years of participation, subject to certain exceptions for
benefits which accrued prior to September 30, 1988. For 2001, the annual benefit
limit was $140,000.

     AMERISOURCE CORPORATION SUPPLEMENTAL RETIREMENT PLAN.  AmeriSource also
maintains a Supplemental Retirement Plan (the "Supplemental Plan"). Coverage
under the Supplemental Plan is limited to certain participants in AmeriSource's
pension plan whose benefits under the pension plan are limited due to (i)
restrictions imposed by the Code on the amount of benefits to be paid from a
tax-qualified plan,

                                        18


(ii) restrictions imposed by the Code on the amount of an employee's
compensation that may be taken into account in calculating benefits to be paid
from a tax-qualified plan, or (iii) any reductions in the amount of compensation
taken into account under the pension plan due to an employee's participation in
certain deferred compensation plans sponsored by AmeriSource or one of its
subsidiaries.

     The Supplemental Plan provides for a supplement to the annual pension
benefit paid under AmeriSource's pension plan to certain participants who have
been employed by AmeriSource for five continuous years or who suffer a total and
permanent disability while employed by AmeriSource or one of its subsidiaries,
and to the pre-retirement death benefits payable under the pension plan on
behalf of such participants who die with a vested interest in AmeriSource's
pension plan. The amount of the supplement will be the difference, if any,
between the pension or pre-retirement death benefit paid under AmeriSource's
pension plan and that which would otherwise have been payable but for the
restrictions imposed by the Code and any reduction in the participant's
compensation for purposes of AmeriSource's pension plan due to his participation
in certain deferred compensation plans of AmeriSource or one of its
subsidiaries.

     The following table shows estimated aggregate annual retirement benefits
that would be payable to participants under AmeriSource's pension plan and, if
applicable, the Supplemental Plan, upon normal retirement at age 65 under
various assumptions as to final average annual compensation and years of
credited service and on the assumption that benefits will be paid in the form of
a single life annuity. The benefit amounts listed are not subject to any
deduction for Social Security benefits.

     BERGEN BRUNSWIG CORPORATION SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN.  Bergen
maintains a non-qualified executive retirement plan ("SERP") providing benefits
to persons in specified compensation and years of service classifications.
Benefits also remain payable under Bergen's Capital Accumulation Plan ("CAP"),
which was the predecessor plan to the SERP and which was frozen to all employee
participants on October 7, 1987.

     On July 27, 2001 Messrs. Dimick, Carpenter and Martini entered into the
Agreements (as defined below in "Agreements With Employees") with the Company.
Pursuant to the Agreements, among other things, Messrs. Dimick, Carpenter and
Martini released all their claims to benefits under the SERP and the CAP.
Although the SERP is still in effect, Messrs. Dimick, Carpenter and Martini have
not accrued any benefits under the SERP since July 27, 2001.

                                        19


     Under the SERP, no benefits are earned or accrued until the participant has
been employed by Bergen for a continuous five full years. Compensation for a
particular year as used for the calculation of retirement benefits under the
SERP includes base salary and bonuses received during the year (including salary
deferred under a salary reduction arrangement) and excludes all other
compensation. Benefits, which are designed to be a certain percentage of the
participant's average monthly compensation over the three calendar years in
which the participant received his or her highest earnings during the
participant's last five years of service, are reduced by the following
approximate amounts: (i) the participant's primary insurance amount payable
under the Social Security Act at retirement age, (ii) the participant's benefit
under the CAP, (iii) an annuitized amount of the employer's contribution towards
Bergen's PIRA Plus Plan, and (iv) any amounts owed by a participant to Bergen
(except to the extent that such amount owed is under a program that expressly
provides that there will not be an offset).

     Benefits are payable under the SERP in the form of a joint and survivor
annuity, consisting of monthly payments to each participant for his or her life
and, upon his or her death, a specified percentage of his or her monthly benefit
to his or her surviving beneficiary for the beneficiary's remaining life. In the
alternative, a participant may elect to receive his or her benefit in a lump
sum. Bergen may direct that any vested benefit of a participant be paid in a
lump sum upon the death of the participant. A $5,000 funeral benefit is
available to a participant's estate. Generally, the CAP benefit is a monthly
retirement benefit paid over a specified number of months that, at the election
of a participant, may be paid in a lump sum. Upon a change in control (as
defined in the CAP and SERP), certain senior executive officers' benefits
payable under the SERP would be accelerated such that their credited years of
service in these plans would be as if they had attained the normal retirement
age. In addition, a master trust (the assets of which are subject to the claims
of Bergen's general creditors) for certain executive officer deferral plans has
been established to preserve these and certain other executive benefits.

     The following table shows the estimated annual benefits payable under the
SERP to eligible participants at age 62, based on a joint and 75 percent
survivor annuity form of retirement income. The table also includes benefits
payable to participants under the CAP.

RETIRED OFFICERS' MEDICAL PLAN

     Bergen maintains an unfunded, non-qualified Retired Officers' Medical Plan
(the "ROM Plan") available to certain named officers of Bergen and their
spouses, including executive officers now retired from Bergen. The ROM Plan
provides for payment of the participant's medical, dental, vision and
prescription expenses at a level commensurate with Bergen's medical benefit
plans that are in effect upon the executive officer's retirement (as defined in
the ROM Plan), but limited to the difference between benefits received from
other insurance sources (including governmental programs), if any, and the total
expense actually incurred. The duration of the benefit is for the lifetime of
the executive officer and the executive officer's spouse at the time of such
officer's retirement. Based upon the various eligibility criteria under the ROM
Plan,

                                        20


Messrs. Dimick, Carpenter and Martini presently are eligible to receive benefits
upon their retirement from the Company. Messrs Yost and Hilzinger will not at
any time be eligible to receive benefits under the ROM Plan.

AGREEMENTS WITH EMPLOYEES

     Effective August 1, 1997, AmeriSource entered into employment agreements
(the "Employment Agreements") with Messrs. Yost and Hilzinger. In connection
with the Merger, the Employment Agreements were assumed by the Company. The
Employment Agreements provide for three-year terms of employment, with an
automatic one-year extension on each anniversary date, annual base salaries
substantially commensurate with present levels, and incentive compensation,
bonuses and benefits in accordance with the Company's prevailing practices from
time to time.

     Each Employment Agreement includes a customary termination for cause
provision, whereupon the Company's obligations under the respective Employment
Agreement would cease by a majority vote of the Board of Directors. The Company
would also be able to terminate the employment of the employee without cause,
whereupon the Company would remain obligated to pay the greater of (i) one year
of such employee's then-current salary and (ii) the base salary of the employee
for the balance of the term of the Employment Agreement. The Employment
Agreements also provide for acceleration of all or a portion of the employee's
stock options then outstanding upon a termination without cause that occurs
prior to certain circumstances. Each Employment Agreement prohibits direct and
indirect competition with the Company for a period of one year after termination
of employment. The Employment Agreements also contain customary prohibitions
against the disclosure of confidential information and the solicitation of the
Company's employees and customers.

     The Employment Agreements provide for certain payments and other benefits
as the result of the termination of the Employment Agreements upon a change of
control of the Company. The Employment Agreements were filed with the Securities
and Exchange Commission ("SEC") as exhibits to AmeriSource's Annual Report on
Form 10-K for the fiscal year ended September 30, 1997. The foregoing
description is qualified in its entirety by reference to such exhibits.

     In April 1994 the Board of Directors of Bergen authorized Bergen to enter
into written employment agreements (the "Bergen Employment Agreements") and
severance agreements (the "Severance Agreements") with certain executive
officers of Bergen, including Mr. Dimick. Similar agreements were entered into
in September 1995 with Messrs. Carpenter and Martini.

     Each of the Bergen Employment Agreements was for a term of three years. The
Employment Agreements automatically extended on a monthly basis so that the
outstanding term was always three years, subject to the option of either party
to terminate the automatic extension provisions at any time. That evergreen
provision was terminated on the Merger Date. Pursuant to each Bergen Employment
Agreement, each of Messrs. Dimick, Carpenter and Martini is to receive his then
effective annual base compensation, a bonus that shall be equal to that paid to
other executive officers at the same level, but, in no event less than fifty
percent of the average of the Named Executive Officer's previous three annual
bonuses, and other benefits and allowances. In the event of death or disability,
each of Messrs. Dimick, Carpenter and Martini or their respective beneficiaries,
as the case may be, will receive the compensation provided for under his Bergen
Employment Agreement for the term of the agreement, calculated as if notice to
terminate had been given 30 days prior to such event.

     Pursuant to the Bergen Employment Agreements, Messrs. Dimick, Carpenter and
Martini may be terminated (i) upon written notice of termination delivered to
the Company by Messrs. Dimick, Carpenter and Martini, as the case may be, except
for "good reason," (ii) by mutual agreement between Messrs. Dimick, Carpenter
and Martini and Bergen, or (iii) by the Company for cause. If a Bergen

                                        21


Employment Agreement is terminated by Bergen for any other reason, or if Messrs.
Dimick, Carpenter and Martini, as the case may be, terminates his employment for
good reason (including, but not limited to, an adverse change in his position
from that held by Messrs. Dimick, Carpenter and Martini, as the case may be,
that existed at the time he entered into his Bergen Employment Agreement), he
will be entitled to damages. The Merger gave each of Messrs. Dimick, Carpenter
and Martini "good reason" to terminate his employment.

     By letter agreements dated July 27, 2001 (the "Agreements"), the Company
and Messrs. Dimick, Carpenter and Martini agreed to a method for calculating the
damages payable under the Bergen Employment Agreements under which (i) salary in
effect at the time of employment termination is deemed to continue at that rate
until the immediately following September 30 and to increase thereafter on each
October 1 by 4%, (ii) bonus is to be calculated as the average of the three
highest bonuses paid over the preceding five years, which amount will then
increase at 4% per annum during the three year period used to calculate damages,
and (iii) the value of all other benefits and perquisites will be deemed to be
$25,000 per year. The amount so determined is then reduced to present value
using a discount rate equal to 120% of the then applicable federal rate
determined under section 1274 of the Code, compounded semiannually.

     The Severance Agreements with Messrs. Dimick, Carpenter and Martini, which
provide for benefits additional to the Bergen Employment Agreements, require
payment of cash and other benefits in the event of a voluntary or involuntary
termination of employment within three years following, but only upon, a Change
in Control (as defined below) of Bergen. Payment under the Severance Agreements
would consist of 2.99 times the annual W-2 compensation paid by Bergen for the
most recent five taxable years of Messrs. Dimick, Carpenter and Martini, as the
case may be, ending before the date of the Change in Control, if, following the
Change of Control, Messrs. Dimick, Carpenter and Martini, as the case may be, is
terminated without cause, the employment of Messrs. Dimick, Carpenter and
Martini, as the case may be, terminates for any reason within 180 days after the
Change in Control, or if Messrs. Dimick, Carpenter and Martini, as the case may
be, terminates his employment for good reason (including, but not limited to, an
adverse change in his position from his position at the time of the Change of
Control). The Severance Agreements continue until three years and one day after
a Change in Control or until Messrs. Dimick, Carpenter and Martini, as the case
may be, receives the severance payment and other benefits he is entitled to
under his Severance Agreement.

     Under the Severance Agreements, the Merger constituted a Change in Control
with respect to Bergen. Messrs. Dimick, Carpenter and Martini were each also
entitled to a lump sum payment of enhanced benefits under the CAP and the SERP,
in the event of a change in control.

     Under the Agreements, the Company and Messrs. Dimick, Carpenter and Martini
confirmed that the Merger constituted a change in control within the meaning of
the Severance Agreements, the CAP and the SERP, and agreed to terminate the
Severance Agreements, the CAP and the SERP, at the Effective Time of the Merger,
in exchange for (i) a lump sum cash payment to each affected executive and (ii)
a release from that executive in favor of the Company, releasing all claims
under his respective Severance Agreement, the CAP and the SERP.

     Pursuant to the Agreements and the accompanying release, Mr. Dimick was
paid $1,837,076 on account of his Severance Agreement and $6,045,990 in
settlement of his SERP benefits; Mr. Carpenter was paid $1,623,920 on account of
his Severance Agreement and $4,185,762 in settlement of his SERP benefits; and
Mr. Martini was paid $1,511,794 on account of his Severance Agreement and
$3,646,570 in settlement of his SERP benefits. None of Messrs. Dimick, Carpenter
or Martini were entitled to benefits under the CAP.

     If any payment or acceleration of any benefits extended from Bergen or the
Company to Messrs. Dimick, Carpenter or Martini upon a change of control were to
be subject to the excise tax imposed by Section 4999 of the Code, then that
executive shall be entitled to receive an additional "gross up bonus" in an
amount necessary to provide the executive with sufficient after income tax funds
to fully pay all such excise taxes on both the payment and the gross up bonus.
                                        22


                              CERTAIN TRANSACTIONS

     In April 1990 Bergen's board of directors approved an unfunded deferred
compensation loan program available to Bergen's executive officers (the "ELP")
for the purpose of providing them with an incentive to remain with Bergen. Under
the ELP, loans were available to certain Bergen executive officers, except those
serving on Bergen's board of directors. Under the original terms of the ELP, (i)
each outstanding loan matures upon the officer's termination of employment
unless extended by Bergen's board and is evidenced by a secured promissory note
in the principal amount of the loan which bears no interest, (ii) an executive
officer could borrow up to 125% of his or her annual salary in effect on the
date of any request, and (iii) the value of collateral securing the loan amount
must equal at least 125% of the principal loan amount. Although no interest is
charged, the employee is deemed by the Internal Revenue Service to have
compensation in the amount of interest calculated according to a formula
prescribed by the Internal Revenue Service. The employee is also deemed to have
paid interest in a like amount to Bergen. Under the ELP, Bergen made loans in
the amounts of $406,250, $281,250, and $281,250 to Mr. Dimick, Mr. Carpenter and
Mr. Martini, respectively.

     In November 1998, Bergen's board of directors adopted an additional loan
program available to the Chief Executive Officer of the Company and those
executive officers directly reporting to him. Such officers may borrow an amount
up to 50% of their annual base salary in effect at the time the loan is granted;
provided, however, that 50% of the loan proceeds must be applied by the
participant towards the purchase of Common Stock. Although no interest was
charged by Bergen to the participant, the participant is deemed by the Internal
Revenue Service to have compensation in the amount of interest calculated
according to a formula prescribed by the Internal Revenue Service. The
participant is also deemed to have paid interest in a like amount to the
Company. Such loan amounts become due and payable upon termination of the
participant's employment with the Company. As of September 30, 2001, the
principal amounts of loans outstanding under the this loan program to the Named
Executive Officers were $212,500, $150,000 and $162,500 for Mr. Dimick, Mr.
Carpenter, and Mr. Martini, respectively.

     In September 1998, Bergen adopted its 1999 Management Stock Accumulation
Plan (the "MSAP"), which was approved by Bergen's stockholders at its 1999
annual meeting, and assumed by the Company in connection with the Merger. This
plan is for the purpose of providing incentive for key executive officers to
remain with the Company and to encourage ownership by them of the Company's
Common Stock.

     Loans granted under the MSAP may be for a term of between one and five
years and in an amount not in excess of three times the executive's annual base
salary in effect at the time the loan is granted; provided, however, that the
aggregate amount of loans issued to any participant under the MSAP may not
exceed $1,000,000. No loan may be issued under the MSAP after September 30,
2004. Loans bear interest at a rate determined by the Board (but not less than
the applicable federal rate set forth under Section 1274(d) of the Code in the
case of any executive who is deemed a "covered employee" under Section 162(m) of
the Code), and is payable on the expiration date of the loan term.

     Loans issued under the MSAP are conditioned upon the participant's
application of the proceeds thereof towards the purchase of the Company's Common
Stock on the open market. The stock so acquired will be held as collateral for
the participant's loan. During the term of the loan, the Compensation Committee
may award credits to participants based upon the attainment for the applicable
performance period of specified performance goals for such period selected by
the Compensation Committee. A participant's accumulated credits, if any, shall
be applied to the repayment of the loan on the loan expiration date provided
that the participant is either employed by the Company or a subsidiary of the
Company on the expiration date or ceases to be so employed due to the
participant's death, disability, retirement after the age of 65 or involuntary
termination of employment other than for cause. In general, in the event of a
Change in Control (as defined in the MSAP), each participant who is in the
employ of the Company or any subsidiary of the Company at such

                                        23


time will continue to be awarded credits for the remainder of the term of the
loan(s) in an amount, or at a rate, which is not less than the greater of the
highest amount, or rate, of credits earned by such participant during any year
of the loan preceding the Change in Control or earned by another participant in
any year following the Change in Control. As of September 30, 2001, there were
no loan amounts outstanding under the MSAP.

     The loans made under the ELP in the amounts of $406,250, $281,250, and
$281,250 to Mr. Dimick, Mr. Carpenter and Mr. Martini, respectively, were
forgiven by Bergen in August 2001. In order to enable Messrs. Dimick, Carpenter
and Martini to pay the income tax they each incurred as a result of the
forgiveness of their loans, Bergen then made additional loans in the amounts of
$180,000, $125,000 and $125,000 to Mr. Dimick, Mr. Carpenter, and Mr. Martini,
respectively. Such loan amounts become due and payable upon the later to occur
of August 7, 2004 and the termination of the executive's employment with the
Company. As of September 30, 2001, the principal amounts outstanding under these
loans to Mr. Dimick, Mr. Carpenter and Mr. Martini were $180,000, $125,000 and
$125,000, respectively.

     Mr. Dimick's employment with the Company will be terminated during the
first half of 2002. In connection with that termination, Mr. Dimick and the
Company have agreed that Mr. Dimick will grant the Company a release of claims
that he might otherwise have against the Company, under his Employment Agreement
or otherwise, and agrees not to accept employment with two of the Company's
major competitors before May 2005. In exchange Mr. Dimick will be paid (i) the
amount of damages calculated in accordance with the methodology agreed to in the
July 27, 2001 letter agreements, approximately $2,788,000, (ii) will be released
from the obligation to mitigate damages contained in his Employment Agreement,
and (iii) will be provided office space and secretarial support for up to one
year following his termination. He will also be allowed to exercise any options
he currently holds to acquire Company stock until September 28, 2002, except
that those that would otherwise have been exercisable for one year following the
termination of his employment will be exercisable for one year from the date he
terminates his service.

                         STOCKHOLDER RETURN PERFORMANCE

     The Merger occurred on August 29, 2001 and the Company's Common Stock began
trading on the New York Stock Exchange on August 30, 2001. As a result, the
cumulative total stockholder return on the Common Stock of the Company cannot be
provided for any period before that date.

     The following graph compares the percentage change in cumulative total
stockholder return on AmeriSource's common stock against the cumulative total
return of the Standard & Poor's 500 Index and an index of peer companies
selected by the Company (the "Peer Group Index") from the market close on
September 30, 1996 to September 30, 2001. Cumulative total return to
stockholders is measured by dividing (x) the sum of (i) total dividends for the
period (assuming dividend reinvestment) and (ii) per-share price change for the
period by (y) the share price at the beginning of the period. The graph is based
on an investment of $100 at the market close on September 30, 1996 in
AmeriSource common stock and in each index.

     Since 1988, the Company has retained Ernst & Young LLP as its independent
auditors and it retained Ernst & Young LLP for the year ending September 30,
2002. Representatives of Ernst & Young LLP are expected to be present at the

Meeting to make a statement, if they desire to do so, and will be available to

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Exchange Act requires the Company's directors and
executive officers and persons who own more than 10% of a registered class of
the Company's equity securities ("10% Stockholders") to file reports of
ownership and changes in ownership of Common Stock and other equity securities
of the Company with the SEC and the New York Stock Exchange. Executive officers,
directors and 10% Stockholders are required by SEC regulations to furnish the
Company with copies of all forms they file under Section 16(a). Based solely on
its review of the copies of such forms received by it and written
representations from certain reporting persons that no other reports were
required from those persons, the Company believes that during the period October
1, 2000 through September 30, 2001, its executive officers, directors and 10%
Stockholders complied with all applicable Section 16(a) filing requirements.

              AUDIT AND CORPORATE RESPONSIBILITY COMMITTEE CHARTER

ORGANIZATION

     There shall be a Committee of the Board of Directors to be known as the
Audit and Corporate Responsibility Committee. The Committee shall review and
reassess the charter at least annually and obtain approval of the Board of
Directors. The Committee, including the Chair thereof, shall be appointed by the
Board of Directors and shall comprise at least three directors who are
independent of the management of the corporation and are free of any
relationship that, in the opinion of the Board of Directors, would interfere
with their exercise of independent judgement as a Committee Member. All
Committee members shall be financially literate, and at least one member shall
have accounting or related financial management expertise.

     It is the responsibility of executive management of AmerisourceBergen
Corporation (the "Company" or the "Corporation") to prepare financial statements
in accordance with generally accepted accounting principles and of the Company's
independent auditor to audit those financial statements. The Audit Committee's
responsibility is one of oversight and in carrying out its responsibility the
Audit Committee is not providing any expert or other special assurance as to the
Company's financial statements.

STATEMENT OF POLICY

     The Audit Committee shall provide assistance to the Board of Directors in
fulfilling its oversight responsibility to the stockholders, potential
stockholders, and investment community relating to the Corporation's financial
statements and the financial reporting practices of the Corporation, and the
quality and integrity of the financial reports of the Corporation. In so doing,
it is the responsibility of the Audit Committee to maintain free and open means
of communication among the directors, the independent auditor, the internal
auditor, and the financial management of the corporation. In discharging its
oversight role, the committee is empowered to investigate any matter brought to
its attention with full access to all books, records, facilities, and personnel
of the Corporation and the power to retain outside counsel, or other experts for
this purpose.

RESPONSIBILITIES AND PROCESSES

     In carrying out its responsibilities, the Audit Committee believes its
policies and procedures should remain flexible in order to best react to
changing conditions and to ensure to the directors and stockholders that the
corporate accounting and reporting practices of the Corporation are in
accordance with all requirements and are of the highest quality. Subject to the
Company's by-laws and resolutions of the Board, the Audit Committee shall meet
at least four times annually at such times as the Chair of the Committee shall
designate.

     In carrying out these responsibilities, the Audit Committee will:

     - Ensure that the outside auditor submits annually a formal written
       statement delineating all relationships between the auditor and the
       Company. The Committee is responsible for engaging in a dialogue with the
       outside auditor with respect to any disclosed circumstances that may
       impact the objectivity and independence of the outside auditor and for
       recommending that the Board of Directors take action as necessary in
       response to the outside auditor's report to satisfy itself of the outside
       auditor's independence.

     - Review and recommend to the Board of Directors the independent auditor to
       be selected to audit the financial statements of the corporation and its
       divisions and subsidiaries. The Committee shall have a clear
       understanding with management and the independent auditor that the
       independent auditor is

                                       A-1


       ultimately accountable to the Board of Directors and the Audit Committee,
       as representatives of the Corporation's stockholders.

     - Meet with the independent auditor and financial management of the
       corporation to review the scope of the proposed audit for the current
       year and the audit procedures to be utilized and at the conclusion
       thereof to review such audit, including any comments or recommendations
       of the independent auditor.

     - Review with the independent auditor, the corporation's internal auditor,
       and financial and accounting personnel, the adequacy and effectiveness of
       the accounting and financial controls of the corporation, and elicit any
       recommendations for the improvement of such internal control procedures
       or particular areas where new or more detailed controls or procedures are
       desirable. Particular emphasis should be given to the adequacy of such
       internal controls to expose any payments, transactions or procedures that
       might be deemed illegal or otherwise improper. Furthermore, the Committee
       annually will review with Internal Audit the Corporation's policy
       statements as they relate to the code of ethics.

     - Review the internal audit function of the Corporation including the
       independence and authority of its reporting obligations, the proposed
       audit plans for the coming year and the coordination of such plans with
       the independent auditor.

     - Receive prior to each meeting a summary of findings from completed
       internal audits and a progress report on the proposed internal audit
       plan, together with explanations for any deviations from the original
       plan.

     - Review with management and the independent auditor the financial
       statements contained in the Annual Report on Form 10-K (or the annual
       report to stockholders, if distributed prior to the filing of Form 10-K)
       to determine that the independent auditor is satisfied with the
       disclosure and content of the financial statements to be presented to the
       stockholders, including its judgement about the quality, not just
       acceptability, of accounting principles, the reasonableness of
       significant judgments, and the clarity of the disclosures in the
       financial statements. Any changes in accounting principles should be
       reviewed. Discuss with the independent auditor the matters required by
       Statement on Auditing Standards No. 61 and based upon the reviews and
       discussion issue its report for inclusion in the Corporation's proxy
       statement.

     - The independent auditor shall review the interim financial statements
       prior to the filing of the Corporation's quarterly Report on Form 10-Q.
       Also, the Committee shall discuss the results of the quarterly review and
       any other matters required to be communicated to the Committee by the
       independent auditor under generally accepted auditing standards. The
       Chair of the Committee may represent the entire committee for this
       purpose.

     - Provide sufficient opportunity for the internal and independent auditor
       to meet with the members of the audit committee without members of
       management present. Among the items to be discussed in these meetings are
       the independent auditor's evaluation of the corporation's financial,
       accounting and auditing personnel, and the level of cooperation that the
       independent auditor received during the course of the audit.

     - Ensure that a Written Affirmation is filed with the New York Stock
       Exchange annually in accordance with the rules and regulations of the New
       York Stock Exchange.

II.  ADMINISTRATION OF THE PLAN

     The Plan Administrator shall have full authority to interpret and construe
any provision of the Plan and to adopt such rules and regulations for
administering the Plan as it may deem necessary or appropriate in order to

VI.  PAYROLL DEDUCTIONS

     A. The payroll deduction authorized by the Participant for purposes of
acquiring shares of Common Stock under the Plan may be any multiple of one
percent (1%) of the Base Salary paid to the Participant during each purchase
period, up to a maximum of twenty-five percent (25%). The deduction rate so
authorized shall continue in effect for the entire purchase period. However, the
Participant may, at any time during the purchase period, reduce his or her rate
of payroll deduction to become effective as soon as possible after filing the
appropriate form with the Plan Administrator. The Participant may not, however,
effect more than one such reduction per purchase period.

     B. Payroll deductions shall begin on the first pay day following the start
date of the purchase period and shall (unless sooner terminated by the
Participant) continue through the pay day ending with or immediately prior to
the last day of the purchase period. The amounts so collected shall be credited
to the Participant's book account under the Plan, but no interest shall be paid
on the balance from time to time outstanding in such account. The amounts
collected from the Participant shall not be held in any segregated account or
trust fund and may be commingled with the general assets of the Company and used
for general corporate purposes.

     C. Payroll deductions shall automatically cease upon the termination of the
Participant's purchase right in accordance with the provisions of the Plan.

VII.  PURCHASE RIGHTS

     A. Grant of Purchase Right.  A Participant shall be granted a separate
purchase right on the start date of each purchase period in which he or she
participates. The purchase right shall provide the Participant with the right to
purchase shares of Common Stock on the Purchase Date upon the terms set forth
below. The Participant shall execute a stock purchase agreement embodying such
terms and such other provisions (not inconsistent with the Plan) as the Plan
Administrator may deem advisable.

     Under no circumstances shall purchase rights be granted under the Plan to
any Eligible Employee if such individual would, immediately after the grant, own
(within the meaning of section 424(d) of the Code or hold outstanding options or
other rights to purchase, stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Company or
any Corporate Affiliate.

     B. Exercise of the Purchase Right.  Each purchase right shall be
automatically exercised on the Purchase Date, and shares of Common Stock shall
accordingly be purchased on behalf of each Participant (other than any
Participant whose payroll deductions have previously been refunded in accordance
with the Termination of Purchase Right provisions below) on such date. The
purchase shall be effected by applying the Participant's payroll deductions for
the purchase period ending on such Purchase Date (together with any carryover
deductions from the preceding purchase period) to the purchase of shares of
Common Stock (subject to the limitation on the maximum number of shares
purchasable per Participant on any one Purchase Date) at the purchase price in
effect for that purchase period.

     C. Purchase Price.  The purchase price per share at which Common Stock will
be purchased on the Participant's behalf on each Purchase Date shall be equal to
eighty-five percent (85%) of the lower of (i) the Fair Market Value per share of
Common Stock on the start date of the purchase period or (ii) the Fair Market
Value per share of Common Stock on that Purchase Date.

                                       B-2


     D. Number of Purchasable Shares.  The number of shares of Common Stock
purchasable by a Participant on each Purchase Date shall be the number of shares
obtained by dividing the amount collected from the Participant through payroll
deductions during the purchase period ending with that Purchase Date (together
with any carryover deductions from the preceding purchase period) by the
purchase price in effect for that Purchase Date. In no event shall fractional
shares be purchased under the Plan.

     E. Excess Payroll Deductions.  Any payroll deductions not applied to the
purchase of Common Stock by reason of the limitation on the maximum number of
shares purchasable by the Participant on the Purchase Date shall be promptly
refunded.

     F. Termination of Purchase Right.  The following provisions shall govern
the termination of outstanding purchase rights:

          (i) A Participant may, at any time prior to the last day of the
     purchase period, terminate his or her outstanding purchase right by filing
     the appropriate form with the Plan Administrator (or its designate), and no
     further payroll deductions shall be collected from the Participant with
     respect to the terminated purchase right. Any payroll deductions collected
     during the purchase period in which such termination occurs shall, at the
     Participant's election, be immediately refunded or held for the purchase of
     shares on the next Purchase Date. If no such election is made at the time
     such purchase right is terminated, then the payroll deductions collected
     with respect to the terminated right shall be refunded as soon as possible.

          (ii) The termination of such purchase right shall be irrevocable, and
     the Participant may not subsequently rejoin the purchase period for which
     the terminated purchase right was granted. In order to resume participation
     in any subsequent purchase period, such individual must re-enroll in the
     Plan (by making a timely filing of the prescribed enrollment forms) on or
     before the start date of the new purchase period.

          (iii) Should the Participant cease to remain an Eligible Employee for
     any reason (including death, disability or change in status) while his or
     her purchase right remains outstanding, then that purchase right shall
     immediately terminate, and all of the Participant's payroll deductions for
     the purchase period in which the purchase right so terminates shall be
     immediately refunded. However, should the Participant cease to remain in
     active service by reason of an approved unpaid leave of absence, then the
     Participant shall have the election, exercisable up until the last business
     day of the purchase period in which such leave commences, to (a) withdraw
     all the funds in the Participant's payroll account at the time of the
     commencement of such leave or (b) have such funds held for the purchase of
     shares at the end of such purchase period. In no event, however, shall any
     further payment deductions be added to the Participant's account during
     such leave. Upon the Participant's return to active service, his or her
     payroll deductions under the Plan shall automatically resume at the rate in
     effect at the time the leave began, provided the Participant returns to
     service prior to the expiration date of the purchase period in which such
     leave began.

     G. Corporate Transaction.  Each outstanding purchase right shall
automatically be exercised immediately prior to the effective date of any
Corporate Transaction by applying the payroll deductions of each Participant for
the purchase period in which such Corporate Transaction occurs to the purchase
of shares of Common Stock at a purchase price per share equal to eighty-five
percent (85%) of the lower of (i) the Fair Market Value per share of Common
Stock on the start date of the purchase period in which such Corporate
Transaction occurs or (ii) the Fair Market Value per share of Common Stock
immediately prior to the effective date of such Corporate Transaction. However,
the applicable share limitation on the number of shares of Common Stock
purchasable per Participant shall continue to apply to any such purchase.

                                       B-3


     The Company shall use its best efforts to provide at least ten (10) days
prior written notice of the occurrence of any Corporate Transaction, and
Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights prior to the effective date of the
Corporate Transaction.

     H. Proration of Purchase Rights.  Should the total number of shares of
Common Stock which are to be purchased pursuant to outstanding purchase rights
on any particular date exceed the number of shares then available for issuance
under the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded.

     I. Assignability.  During the Participant's lifetime, the purchase right
shall be exercisable only by the Participant and shall not be assignable or
transferable by the Participant (other than by will or the laws of descent).

     J. Stockholder Rights.  A Participant shall have no stockholder rights with
respect to the shares subject to his or her outstanding purchase right until the
shares are purchased on the Participant's behalf in accordance with the
provisions of the Plan and the Participant has become a holder of record of the
purchased shares.

VIII.  ACCRUAL LIMITATIONS

     A. No participant shall be entitled to accrue rights to acquire Common
Stock pursuant to any purchase right outstanding under this Plan if and to the
extent such accrual, when aggregated with (i) rights to purchase Common Stock
accrued under any other purchase right granted under this Plan and (ii) similar
rights accrued under other employee stock purchase plans (within the meaning of
section 423 of the Code) of the Company or any Corporate Affiliate, would
otherwise permit such Participant to purchase more than $25,000 worth of stock
of the Company or any Corporate Affiliate (determined on the basis of the Fair
Market Value of such stock on the date or dates such rights are granted) for
each calendar year such rights are at any time outstanding.

     B. For purposes of applying such accrual limitations, the following
provisions shall be in effect:

          (i) The right to acquire Common Stock under each outstanding purchase
     right shall accrue on the Purchase Date in effect for the purchase period
     for which such right is granted.

          (ii) No right to acquire Common Stock under any outstanding purchase
     right shall accrue to the extent the Participant has already accrued in the
     same calendar year the right to acquire Common Stock under one (1) or more
     other purchase rights at a rate equal to $25,000 worth of Common Stock
     (determined on the basis of the Fair Market Value of such stock on the date
     or dates of grant) for each calendar year such rights were at any time
     outstanding.

     C. If by reason of such accrual limitations, any purchase right of a
Participant does not accrue for a particular purchase period, then the payroll
deductions which the Participant made during that purchase period with respect
to such purchase right shall be promptly refunded.

     D. In the event there is any conflict between the provisions of this
Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

IX.  EFFECTIVE DATE AND TERM OF THE PLAN

     A. The Plan was adopted by the Board on January 18, 2002 and shall become
effective on such date, provided no purchase rights granted under the Plan shall
be exercised, and no shares of Common Stock shall be issued hereunder, until (i)
the Plan shall have been approved by the shareowners of the Company and

                                       B-4


(ii) the Company shall have complied with all applicable requirements of the
1933 Act (including the registration of the shares of Common Stock issuable
under the Plan on a Form S-8 registration statement filed with the Securities
and Exchange Commission), all applicable listing requirements of any stock
exchange on which the Common Stock is listed for trading and all other
applicable requirements established by law or regulation. In the event such
stockholder approval is not obtained, or such compliance is not effected, within
twelve (12) months after the date on which the Plan is adopted by the Board, the
Plan shall terminate and have no further force or effect and all sums collected
from Participants during the initial purchase period hereunder shall be
refunded.

     B. Unless sooner terminated by the Board, the Plan shall terminate upon the
earliest of (i) January 1, 2012, (ii) the date on which all shares available for
issuance under the Plan have been sold pursuant to purchase rights exercised
under the Plan or (iii) the date on which all purchase rights are exercised in
connection with a Corporate Transaction. No further purchase rights shall be
granted or exercised, and no further payroll deductions shall be collected,
under the Plan following its termination.

X.  AMENDMENT OF THE PLAN

     The Board may alter, amend, suspend or discontinue the Plan at any time.
However, the Board may not, without the approval of the Company's shareowners,
(i) increase the number of shares of Common Stock issuable under the Plan or the
maximum number of shares purchasable per Participant on any one Purchase Date,
except for permissible adjustments in the event of certain changes in the
Company's capitalization, (ii) alter the purchase price formula so as to reduce
the purchase price payable for the shares of Common Stock purchasable under the
Plan, or (iii) materially increase the benefits accruing to Participants under
the Plan or materially modify the requirements for eligibility to participate in
the Plan. In the event that the Plan is terminated prior to the last day of a
purchase period, such purchase period shall be deemed to have ended on the
effective date of such termination and there shall be no subsequent purchase
periods thereafter.

XI.  GENERAL PROVISIONS

     A. All costs and expenses incurred in the administration of the Plan shall
be paid by the Company.

     B. Nothing in the Plan shall confer upon the Participant any right to
continue in the employ of the Company or any Corporate Affiliate for any period
of specific duration or interfere with or otherwise restrict in any way the
rights of the Company (or any Corporate Affiliate employing such person) or of
the Participant, which rights are hereby expressly reserved by each, to
terminate such person's employment at any time for any reason, with or without
cause.

Until you send in your old certificates, we cannot establish a registered

communications that we send to the registered holders of AmerisourceBergen

I urge you to exchange your certificates as soon as possible. If you have any
questions or would like assistance with the paperwork call Mellon Investor
Services LLC, Exchange Agent at 1-866-203-6613.
