                                    PART I
 
ITEM 1. BUSINESS
 
  AmeriSource Health Corporation, through its direct wholly-owned subsidiary
AmeriSource Corporation (referred to interchangeably as "AmeriSource" and the
"Company"), is the fifth largest full-service wholesale distributor of
pharmaceutical products and related health care services in the United States.
The Company services its customers nationwide through 19 drug distribution
facilities and one specialty products distribution facility. AmeriSource is
typically the primary source of supply to its customers and offers a broad
range of services designed to enhance the operating efficiencies and
competitive position of its customers and suppliers. The Company benefits from
a diverse customer base that includes hospitals and managed care facilities
(47%), independent community pharmacies including retail drug stores, nursing
homes and clinics (35%) and chain drug stores including pharmacy departments
of supermarkets and mass merchandisers (18%).
 
  Over the past five years, AmeriSource has achieved significant growth in
revenues and operating income before unusual items. The Company's revenues
have increased from $2.5 billion in fiscal 1990 to $4.7 billion in fiscal
1995, a compound annual growth rate of 13.5%, while operating income before
unusual items and amortization increased from $43.8 million in fiscal 1990 to
$98.0 million in fiscal 1995, a compound annual growth rate of 17.5%. The
Company's growth is primarily the result of market share gains in existing
markets, geographic expansion and overall industry growth.
 
  AmeriSource Health Corporation was incorporated in Delaware in 1988. The
address of the principal executive office of the Company is P.O. Box 959,
Valley Forge, Pennsylvania 19482. The telephone number is (610) 296-4480.
 
BUSINESS STRATEGY
 
  Over the past five years, AmeriSource has significantly expanded its
national presence as a leading, innovative wholesale distributor of
pharmaceutical products and related health care services. The Company believes
it is well-positioned to continue its revenue growth and increase operating
income through the execution of the following key elements of its business
strategy:
 
  . Expanding into New Geographic Markets. The Company believes that there
    are substantial opportunities to grow by expanding into new geographic
    areas through opening new distribution facilities and making selective,
    complementary acquisitions. Since October 1993, the Company has opened
    six new distribution facilities. In October 1993, the Company opened a
    facility in Dallas, Texas, and in November 1994, the Company opened two
    additional facilities in Portland, Oregon and Springfield, Massachusetts.
    In June 1995 the Company opened a new facility in Sacramento, California
    and in October 1995, a new facility in Phoenix, Arizona was opened. On
    December 1, 1995, the Company opened its newest facility in Orlando,
    Florida. Each of these new facilities began operations with an existing
    customer base in its regional marketplace. In addition, in July 1995, the
    Company acquired Newbro Drug Company, a regional wholesale pharmaceutical
    distributor based in Idaho Falls, Idaho. The Company believes that as
    industry consolidation pressures continue, additional opportunities may
    arise to selectively acquire additional local and regional drug wholesale
    companies facilitating expansion into new geographic areas and
    enhancement of its competitive position in existing markets.
 
  . Increasing Market Share in Existing Markets. The Company believes that it
    is well positioned to continue to grow in its existing markets by: (i)
    providing superior distribution services and specialty value-added
    programs which reduce its customers' cost of operations; (ii) maintaining
    its low cost operating structure to ensure that the Company's services
    are priced competitively in the marketplace; (iii) continuing to focus on
    the higher growth hospital and managed care market segment through the
    use of dedicated facilities and advanced information systems; and (iv)
    maintaining its decentralized operating structure to respond to
    customers' needs more quickly and efficiently and to ensure the continued
    development of local and regional management talent. These factors have
    allowed AmeriSource to compete effectively in the marketplace, generate
    above-average industry sales growth over the last two years and develop
    new customers, such as the federal government. For example, over the past
    two years the Company
 
                                       1
<PAGE>
 
   has been awarded contracts to provide approximately 75% of the
   pharmaceuticals purchased by federal government hospital facilities
   nationwide. In addition, the Company continues to grow with its existing
   customers. The Company was selected by VHA Inc. as one of its three
   primary providers and has been chosen as the preferred provider for
   SunHealth. Both customers are among the nation's largest healthcare
   providers.
 
  . Continuing Growth of Specialty Services. The Company works closely with
    both customers and suppliers to develop an extensive range of specialty
    services. In addition to enhancing the Company's profitability, these
    services increase customer loyalty and strengthen the Company's overall
    role in the healthcare distribution channel. These services include:
 
    --ECHO(TM), the Company's proprietary software system, provides
     sophisticated ordering and inventory management assistance to its
     hospital and retail customers. In addition to facilitating the primary
     supply arrangement between the Company and its customers, ECHO(TM)
     enables the Company's customers to reduce their costs through ordering
     more efficiently, selecting from best price alternatives and
     maintaining formulary compliance. In fiscal 1995, the Company acquired
     Liberty Drug Systems, a software developer based in Greensboro, North
     Carolina. The technology acquired with this acquisition is being
     combined with the ECHO(TM) system to provide customers with a complete
     system for tracking usage, reordering products and managing records.
     Since the introduction of ECHO(TM) in early fiscal 1991, the Company
     has installed approximately 3,000 systems nationwide, and believes that
     its installed base of systems is one of the largest in the wholesale
     drug industry.
 
    --Family Pharmacy(R) enables small chain and independent community
     pharmacies to compete more effectively through: (i) innovative
     advertising, marketing and promotional campaigns; (ii) value-added
     merchandising programs including private label product lines; and (iii)
     enhanced access to pharmaceutical benefit programs of large health care
     groups, including third party payor programs. Family Pharmacy(R) has
     grown dramatically in recent years. With approximately 2,000 Family
     Pharmacy(R) member-stores, Family Pharmacy(R) in effect constitutes one
     of the largest drugstore chains in the United States.
 
    --The Company's Income Rx(R) program provides an integral value-added
     service to its hospital and retail pharmacist customers by continually
     reviewing the marketplace for generic products that offer the best
     price, quality and availability. With the increasing importance of
     generic pharmaceuticals this program represents a significant
     opportunity for growth and profitability. Revenues attributable to
     AmeriSource's sale of generic and multi-source pharmaceuticals
     (including through the Income Rx(R) program) have increased to
     approximately $500 million in fiscal 1995, more than twice what they
     were in fiscal 1992.
 
    --AmeriSource operates a pharmaceutical repackaging business that
     markets products through its Income RePax(R) program. Repackaging
     pharmaceuticals from bulk quantities into smaller units provides the
     Company's customers with lower product, inventory and dispensing
     (labor) costs.
 
    --The Company's Health Services Plus business distributes oncology and
     other specialty products to clinics and physician groups on a national
     basis. Rita Ann Distributors markets cosmetics and fragrances to chain
     drugstores and independent retail customers.
 
  . Maintain Low Cost Operating Structure. AmeriSource has the lowest
    operating cost structure among its four major national competitors. Over
    the past five years, the Company has significantly reduced operating
    expenses and investment in net working capital as a percentage of
    revenues. Specifically, the Company has reduced its selling and
    administrative expenses and depreciation as a percentage of revenues from
    4.78% in fiscal 1990 to 3.61% in fiscal 1995. In addition, the Company
    continues to achieve productivity and operating income gains from
    continued investments in advanced management information systems,
    warehouse automation technology, and from operating leverage due to above
    industry average volume per facility. In fiscal 1995, the Company's
    average revenue per facility was $246 million compared to a calendar 1994
    industry average of $213 million. The addition of new facilities was
    accomplished with minimal incremental investment in corporate overhead.
    As these facilities continue to expand in their regional markets, the
    Company believes that its growth and profitability will be further
    enhanced.

INDUSTRY OVERVIEW
 
  The Company has benefited from the significant growth of the full-service
drug wholesale industry in the United States. Industry sales grew from $30
billion in 1990 to an estimated $52 billion in 1994. The factors contributing
to this growth, and the sources of future growth for the industry, include (i)
an aging population, (ii) the introduction of new pharmaceuticals, (iii) the
increased use of outpatient drug therapies, (iv) a higher concentration of
distribution through wholesalers by both manufacturers and customers, and (v)
rising pharmaceutical prices.
 
  Aging Population. The number of individuals over age 65 in the United States
has grown 23% from approximately 26 million in 1980 to approximately 32
million in 1990 and is projected to increase an additional 9% to more than 35
million by the year 2000. This age group suffers from a greater incidence of
chronic illnesses and disabilities than the rest of the population and is
estimated to account for approximately two-thirds of total health care
expenditures in the United States.
 
  Introduction of New Pharmaceuticals. Traditional research and development as
well as the advent of new research and production methods, such as
biotechnology, continue to generate new compounds that are more effective in
treating diseases. These compounds have been responsible for significant
increases in pharmaceutical sales. The Company believes that ongoing research
and development expenditures by the leading pharmaceutical manufacturers will
contribute to continued growth of the industry.
 
  Cost Containment Efforts. In response to rising health care costs,
governmental and private payors have adopted cost containment measures that
encourage the use of efficient drug therapies to prevent or treat diseases.
While national attention has been focused on the overall increase in aggregate
health care costs, the Company believes drug therapy has had a beneficial
impact on overall health care costs by reducing expensive surgeries and
prolonged hospital stays. Pharmaceuticals currently account for less than 9%
of overall healthcare costs, and manufacturers' emphasis on research and
development is expected to continue the introduction of cost effective drug
therapies.
 
  Higher Concentration of Distribution Through Wholesalers. Over the past
decade, manufacturers of pharmaceuticals have significantly increased the
distribution of their products through wholesalers as the cost and complexity
of maintaining inventories and arranging for delivery of pharmaceutical
products has risen. Drug wholesalers offer their customers and suppliers more
efficient distribution and inventory management. As a result, from 1980 to
1994, the percentage of pharmaceutical sales through wholesale drug
distributors increased from approximately 57% to approximately 78%. Order
processing, inventory management and product delivery by wholesale drug
distributors allow manufacturers to allocate their resources to research and
development, manufacturing and marketing their products. Customers benefit
from this shift by having a single source of supply for a full line of
pharmaceutical products as well as lower inventory costs, more timely and
efficient delivery, and improved purchasing and inventory information. In
addition, customers also benefit from the range of value-added programs
developed by wholesale drug distributors that are targeted to the specific
needs of these customers, which, in turn, reduce their costs and increase
their operating efficiencies.
 
  Pharmaceutical Price Increases By Drug Manufacturers. The Company believes
that price increases by pharmaceutical manufacturers will continue to equal or
exceed the overall Consumer Price Index. The Company believes that this
increase will be due in large part to the relatively inelastic demand in the
face of higher prices charged for patented drugs as manufacturers have
attempted to recoup costs associated with the development, clinical testing
and Food and Drug Administration ("FDA") approval of new products.
 
  At the same time that sales through the wholesale drug industry have grown,
the number of pharmaceutical wholesalers in the United States has decreased
from 139 at the end of 1980 to approximately 48 as of December 1995. Industry
analysts expect this consolidation trend to continue, with the industry's
largest companies increasing their percentage of total industry sales.
 
                                       3

OPERATIONS
 
  Decentralized Structure. The Company believes that operating economies of
scale exist principally at the distribution facility level. Beginning in fiscal
1989, the Company undertook an extensive consolidation program, which closed 17
of the 31 facilities open on October 1, 1988. During the course of this
consolidation program, the Company continued to significantly increase its
revenues in each fiscal year. During fiscal 1995, the Company's average revenue
per facility was approximately $246 million, compared to the calendar 1994
industry average of $213 million. Five AmeriSource facilities each have annual
volume of over $400 million and an additional five facilities each have annual
volume in excess of $213 million, which provides the Company with continued
opportunities for significant leverage of fixed overhead and other costs.
 
  To expand into new geographic markets, AmeriSource has opened six new
facilities since October 1993, and currently operates 19 drug wholesale
distribution facilities and one specialty products distribution facility,
organized into four regions across the United States. Several operating units
of the Company have over 100 years of history in the business and are among the
nation's first drug distribution businesses. Unlike its more centralized
competitors, the Company is structured as an organization of locally managed
profit centers. Management of each operating unit has fiscal responsibility for
its unit, and each operating unit has an established executive, sales and
operations staff. The operating unit's results, including earnings and asset
management goals, have a direct impact on management compensation. The
operating units utilize the Company's corporate staff for marketing, financial,
legal and executive management resources and corporate coordination of asset
and working capital management.
 
  Sales and Marketing. The Company has an organization of over 200 sales
professionals. A specially trained group of telemarketing/customer service
representatives makes regular contact with customers regarding special offers.
Within the sales organization, there is also a field force of approximately 50
hospital representatives, including regional hospital directors. The Company's
corporate marketing department works with manufacturer suppliers to develop
national programs and promotions. Tailored to specific customer classes, these
programs can be further customized at the operating unit level to adapt to
local market conditions. The marketing department gathers and disseminates
information to each operating unit's purchasing and sales organization in order
to enhance their competitive effectiveness.
 
  Facilities. Each of the Company's operating units carries an inventory line
necessary for its local market. The efficient distribution of small orders is
possible through the extensive use of computerization and modern warehouse
techniques. These include computerized warehouse product location, routing and
inventory replenishment systems, gravity-flow racking, mechanized order
selection and efficient truck loading and routing. The Company delivers its
products on a scheduled basis, including on a daily basis where required. It
utilizes a fleet of owned and leased vans and trucks and contract carriers.
Night picking operations in its distribution facilities have further reduced
delivery time. According to customer need, orders can be delivered in fewer
than 24 hours.
 
  The Company's 19 full service distribution facilities and one specialty
products facility as of December, 1995, are organized into four regions
throughout the United States. The following table presents certain information
regarding the Company's operating units in the aggregate.

  No single customer represented more than 4% of the Company's total revenues
during fiscal 1995 other than the federal government which, in the aggregate,
accounted for approximately 10%. Excluding the federal government, the
Company's top ten customers represented approximately 15% of total revenues
during fiscal 1995. The Company believes it is less dependent on any single
customer than its four largest competitors. A profile of each customer segment
follows:
 
  . Hospitals and Managed Care Facilities. AmeriSource is one of the nation's
    top three distributors in serving the hospital and managed care market
    segment, which is currently the fastest growing customer segment in the
    industry. Because hospitals and managed care facilities purchase large
    volumes of high priced, easily handled pharmaceuticals, the Company
    benefits from quick turnover of both inventory and receivables and lower
    than average operating expenses. The Company intends to continue to focus
    on the higher growth hospital and managed care market segment through the
    use of dedicated facilities and advanced information systems such as
    ECHO(TM). As a percentage of total revenues, sales to hospitals and
    managed care facilities increased from 36% in fiscal 1991 to 47% in
    fiscal 1995, and have grown at a compound rate of 21.5% over this period.
 
  . Independents. Independent community pharmacy owners represent the largest
    segment of the industry and provide the greatest opportunity for the
    Company's value-added services. The Company's sales to independent
    customers have risen at a compound rate of 8.0% from fiscal 1991 through
    fiscal 1995 due to the general growth of this customer segment and to the
    success of the Company's customized marketing and merchandising programs,
    such as its Family Pharmacy(R) program.
 
  . Chains. This category includes chain drug stores, including pharmacy
    departments of supermarkets and mass merchandisers. The Company's sales
    to chains have risen at a compound rate of 12.0% from fiscal 1991 through
    fiscal 1995. This growth rate reflects the results from the Company
    entering into new contracts with several drug store chains.
 
  Suppliers. AmeriSource obtains pharmaceutical and other products from a
number of manufacturers, none of which account for more than approximately 6%
of its net sales in fiscal 1995. The five largest suppliers in fiscal 1995
accounted for approximately 23% of net sales. Historically, the Company has
not experienced difficulty in purchasing desired products from suppliers. The
Company has agreements with many of its suppliers which generally require the
Company to maintain an adequate quantity of a supplier's products in
inventory. The majority of contracts with suppliers are terminable upon 30
days notice by either party. The loss of certain suppliers could adversely
affect the Company's business if alternative sources of supply were
unavailable. The Company believes that its relationships with its suppliers
are good.

  Management Information Systems. The Company has continually invested in
advanced management information systems and automated warehouse technology. In
fiscal 1994, AmeriSource introduced its BOSS warehouse automation system, a
paperless warehouse production program customized to AmeriSource's unique
requirements. First installed at its Paducah, Kentucky distribution center,
the second BOSS system will be installed at the Company's newly opened
facility in Orlando, Florida. Under the BOSS system, merchandise is received,
placed in inventory, retrieved and shipped utilizing customized radio
frequency equipment. The Company's management information systems also provide
for, among other things, electronic order entry by customers, invoice
preparation and purchasing and inventory tracking. As a result of electronic
order entry, the cost of receiving and processing orders have not increased as
rapidly as sales volume. The Company's customized systems strengthen customer
relationships by allowing the customer to lower its operating costs and by
providing the basis for a number of the value-added services the Company
provides to its customers, including marketing data, inventory replenishment,
single-source billing, computer price updates and price labels. AmeriSource
believes that its management information systems are capable of serving its
needs for the foreseeable future.
 
COMPETITION
 
  The Company engages in the wholesale distribution of pharmaceuticals, health
and beauty aids and other products in a highly competitive environment. The
Company competes with numerous national and regional distributors, some of
which are larger and have substantially greater financial resources than the
Company. The Company's national competitors include McKesson Corporation,
Bergen Brunswig Corporation, Cardinal Health, Inc. and FoxMeyer Health
Corporation. In addition, the Company competes with local distributors,
direct-selling manufacturers and other specialty distributors. Competitive
factors include price, service and delivery, credit terms, breadth of product
line, customer support and marketing programs. There can be no assurance that
the Company will not encounter increased competition in the future that could
adversely affect the Company's business. The drug wholesale industry continues
to undergo significant consolidation, with the number of wholesalers in the
continental United States reduced from 139 at the end of 1980 to approximately
48 as of December 1995.
 
EMPLOYEES
 
  As of September 30, 1995, the Company employed approximately 2,600 persons,
of which approximately 2,400 were full-time employees. Approximately 11% of
full and part-time employees are covered by collective bargaining agreements.
The Company believes that its relationship with its employees is good.
 
REGULATORY MATTERS
 
  The United States Drug Enforcement Administration, the FDA and various state
boards of pharmacy regulate the distribution of pharmaceutical products and
controlled substances, requiring wholesale distributors of these substances to
register for permits and to meet various security and operating standards. As
a wholesale distributor of pharmaceuticals and certain medical/surgical
products, the Company is subject to these regulations. The Company has
received all necessary regulatory approvals and believes that it is in
substantial compliance with all applicable wholesale distribution
requirements.
 
  The Company is aware that at its former Charleston, South Carolina
distribution center there is evidence of residual soil contamination remaining
from the fertilizer manufacturing process operated on that site over thirty
years ago. The Company's environmental consulting firm conducted a soil survey
and a groundwater study during fiscal 1994 and 1995. The results of the
studies indicate that there is lead on-site at levels requiring further
investigation and potential remediation. A preliminary engineering analysis
was prepared by outside consultants during the third quarter of fiscal 1994,
and indicated that if both soil and groundwater remediation are required, the
most likely cost is estimated to be $4.1 million. Accordingly, a liability of
$4.1 million was recorded during
 
                                       6
<PAGE>
 
fiscal 1994 to cover future consulting, legal and remediation and ongoing
monitoring costs. The Company is working with the appropriate state regulatory
agency regarding further tests and potential site remediation. That
negotiation, investigation and remediation could take several years and the
actual costs may differ from the liability that has been recorded. The accrued
liability ($3.9 million at September 30, 1995), which is reflected in other
long-term liabilities on the Company's consolidated balance sheet, is based on
the present estimate of the extent of contamination, choice of remedy, and
enacted laws and regulations, including remedial standards; however, changes
in any of these could affect the estimated liability. The Company is
investigating the possibility of asserting claims against responsible parties
for recovery of these costs. Whether or not any recovery may be forthcoming is
unknown at this time, although the Company intends to vigorously enforce its
rights and remedies.
 
ITEM 2. PROPERTIES
 
  As of December 1995, the Company conducted its business from office and
operating unit facilities at 33 locations throughout the United States. In the
aggregate, the Company's operating units occupy approximately 1.9 million
square feet of office and warehouse space, of which approximately 782,000
square feet is owned and the balance is leased under lease agreements with
expiration dates ranging from 1996 to 2009. The Company's 21 drug distribution
facilities range in size from approximately 43,600 square feet to 213,000
square feet. Leased facilities are located in the following states: Arizona,
California, Florida, Idaho, Kentucky, Massachusetts, Minnesota, New Jersey,
North Carolina, Ohio, Oregon, Pennsylvania, Tennessee and Texas. Owned
facilities are located in the following states: Georgia, Indiana, Kentucky,
Maryland, Missouri, Ohio, Pennsylvania, Tennessee and Virginia. The Company
utilizes a fleet of owned and leased vans and trucks, as well as contract
carriers to deliver its products. The Company believes that its properties are
adequate to serve the Company's current and anticipated needs without making
capital expenditures materially higher than historical levels.
 
ITEM 3. LEGAL PROCEEDINGS
 
  In November 1993, the Company was named a defendant, along with six other
wholesale distributors and twenty-four pharmaceutical manufacturers, in a
series of purported class action antitrust lawsuits alleging violations of
various antitrust laws associated with the chargeback pricing system. In
addition, the Company is a party to a parallel suit filed in state court in
Minnesota. The actions were originally filed in the United States District
Court for the Southern District of New York, and have been transferred to the
United States District Court for the Northern District of Illinois for
consolidated and coordinated pretrial proceedings. In essence, these lawsuits
all claim that the manufacturer and wholesaler defendants have combined,
contracted and conspired to fix the prices charged to plaintiff independent
retail pharmacies and class members for prescription brand name
pharmaceuticals. Specifically, plaintiffs claim that the defendants use
"chargeback agreements" to give some institutional pharmacies discounts that
are not made available to retail drug stores. Plaintiffs seek injunctive
relief, treble damages, attorneys' fees and costs. In October, 1994, the
Company entered into a Judgement Sharing Agreement with other wholesaler and
pharmaceutical manufacturer defendants. Under the Judgement Sharing Agreement:
(a) the manufacturer defendants agreed to reimburse the wholesaler defendants
for litigation costs incurred, up to an aggregate of $9 million; and (b) if a
judgement is entered into against both manufacturers and wholesalers, the
total exposure for joint and several liability of the Company is limited to
the lesser of 1% of such judgement or $1 million. In addition, the Company has
released any claims which it might have had against the manufacturers for the
claims presented by the plaintiffs in these lawsuits. The Judgement Sharing
Agreement covers the federal court litigation as well as the cases which have
been filed in various state courts. The Company believes it has meritorious
defenses to the claims asserted in these lawsuits and intends to vigorously
defend itself in all of these cases.
 
  In October 1995, a proceeding was instituted before the Massachusetts Board
of Registration in Pharmacy (the "Board") against the Company. The Board
alleges that the Company's application for the licensure of its facility in
Springfield, Massachusetts submitted in September 1994 was inaccurate and
insufficient. The Company is contesting this allegation. The Company cannot
predict the outcome of the proceeding; however, it does not believe that the
outcome will have a material adverse effect on its business or financial
condition.

  The Company is a party to various lawsuits arising in the ordinary course of
business. The Company, however, does not believe that the outcome of these
lawsuits, individually or in the aggregate, will have a material adverse
effect on its business or financial condition.

ITEM 5. MARKET FOR REGISTRANTS' COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.
 
  Since April 10, 1995, the Company's Class A Common Stock has been traded
over-the-counter in the National Market System of the National Association of
Securities Dealers, Inc. (Nasdaq symbol ASHC). Prior to that date, there was
no established public trading market for the Company's Class A Common Stock.
As of December 8, 1995, there were 313 record holders of the Company's Class A
Common Stock. The quarterly high and low closing prices for the Company's
Class A Common Stock since April 1995 ranged from $24 1/2 to $20 3/4,
respectively, in the third quarter and from $27 3/4 to $19 3/4, respectively,
in the fourth quarter.
 
  There is no established public trading market for the Company's Class B
Common Stock. As of December 8, 1995, there were 11 record holders of the
Company's Class B Common Stock.
 
  The Company's Class C Common Stock was held by 14 holders of record as of
December 8, 1995. The Class C Common Stock trades on a limited basis in the
over-the-counter market, and information concerning the historical trading
prices for the Class C Common Stock is not published by nationally-recognized
independent sources.
 
  The Company has not paid any cash dividends to its stockholders on any class
of its Common Stock, and anticipates that for the forseeable future its
earnings will be retained for use in its business. Payment of dividends is
within the discretion of the Company's Board of Directors and will depend,
among other factors, upon the Company's earnings, financial condition and
capital requirements and the terms of the Company's financing agreements. A
credit agreement between the Company and a syndicate of senior lenders
provides a secured credit facility of $380 million, and restricts the
Company's ability to make dividend payments unless certain financial tests are
met.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
 
                        AMERISOURCE HEALTH CORPORATION
 
                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion should be read in conjunction with the Consolidated
Financial Statements contained herein.
 
RESULTS OF OPERATIONS
 
YEAR ENDED SEPTEMBER 30, 1995 COMPARED WITH YEAR ENDED SEPTEMBER 30, 1994
 
  Revenues of $4.7 billion for the fiscal year ended September 30, 1995
represented an increase of 11.6% over revenues for the fiscal year ended
September 30, 1994. The year-to-year revenue gains reflect increases across
all customer groups, the impact of the Company's expansion into new geographic
markets, especially in the northeastern and western United States, and price
increases. During the fiscal year ended September 30, 1995, sales to hospitals
increased 11%, sales to independent drug store customers increased 13%, and
sales to the chain drug store customer group increased 11%, as compared with
the prior fiscal year. During the twelve months ended September 30, 1995,
sales to hospitals accounted for 47% of total revenues, while sales to
independent drug stores represented 35% and sales to chain drug stores, 18% of
the total.
 
  Gross profit of $266.4 million for fiscal 1995 increased by 13.3% over 1994,
primarily due to the increase in revenues. As a percentage of revenues, the
Company's gross profit margin expanded to 5.70% from 5.62% in 1994. The gross
profit margin improvement was a result of increased sales of higher margin
generic drugs, the continued introduction of new marketing programs with
manufacturers, and growth of higher margin specialty businesses, such as
pharmaceutical packaging. Increased purchase discounts and a greater level of
price increases from manufacturers resulting in greater inventory appreciation
also benefited the gross profit margin.
 
                                       9
<PAGE>
 
  Selling and administrative expenses and depreciation for 1995 were $168.3
million compared to $149.1 million for 1994, an increase of 12.9%. The
increase in 1995 is due primarily to increases in warehouse and delivery
expenses relating to the volume increases, development expenses of value-added
programs, and one-time costs associated with the opening of new distribution
facilities in Springfield, Massachusetts, Portland, Oregon, Sacramento,
California, and Phoenix, Arizona. As a result of these factors, selling and
administrative expenses and depreciation increased slightly to 3.61% of
revenues compared to 3.57% in fiscal 1994.
 
  The decrease in amortization in fiscal 1995 was as a result of the write-off
of the value of the excess of cost over net assets acquired ("goodwill") which
the Company recorded in the third quarter of fiscal 1994.
 
  Operating income, excluding unusual items and amortization, of $98.0 million
for fiscal 1995 increased 13.9% over fiscal 1994. As a percentage of revenues,
the Company's operating margin, excluding unusual items and amortization,
expanded to 2.10% in 1995 from 2.06% in 1994.
 
  Interest expense (excluding the amortization of deferred financing costs)
for the year ended September 30, 1995 was $49.8 million, a decrease of $8.8
million, or 15.1% as compared with the year ended September 30, 1994. The
decrease was due to the redemption, in January 1995, of the $166.1 million of
14 1/2% senior subordinated notes, the redemption, in May 1995, of $74.3
million of 11 1/4% senior debentures, and the lower average rates due to the
implementation of the Receivables Program and the new revolving credit
facility which has a lower interest rate than the previous facility. Average
borrowings were $536 million during fiscal 1995 versus $562 million in 1994.
 
  Income taxes provided of $17.3 million in fiscal 1995 were based upon an
annual effective tax rate of 38%, which recognizes the utilization, for
financial reporting purposes, of operating loss carryforwards. The provision
for income taxes in fiscal 1994 represents the estimated taxes payable due to
the application of the alternative minimum tax. The extraordinary charge of
$25.2 million in 1995, net of a tax benefit of $7.2 million, relates to the
amendment of the Credit Agreement, the redemption premium on the 14 1/2%
senior subordinated notes, the redemption premium on the 11 1/4% senior
debentures, and the consequent write-off of unamortized deferred financing
fees. The extraordinary charge of $679,000 in 1994, net of a tax benefit of
$23,000, relates to the purchase and retirement of an aggregate principal
amount of $4.4 million of 14 1/2% senior subordinated notes.
 
YEAR ENDED SEPTEMBER 30, 1994 COMPARED WITH YEAR ENDED SEPTEMBER 30, 1993
 
  Revenues of $4.2 billion for the fiscal year ended September 30, 1994
represented an increase of 14.3% over the amount for the fiscal year ended
September 30, 1993, reflecting real volume growth as well as the pass through
to customers of price increases from manufacturers. As compared with the prior
fiscal year, sales to hospitals grew by 27%, sales to chain drug stores,
excluding brokerage business, increased by 8%, and sales to independent drug
store customers increased by 4%. During 1994, sales to hospitals accounted for
47% of total revenues, while sales to independent drug stores represented 35%
and sales to chain drug stores, 18% of the total.
 
  Gross profit of $235.2 million for 1994 increased by 12.3% over 1993,
primarily due to the increase in revenues. As a percentage of revenues, gross
profit declined to 5.62% in 1994 from 5.72% in 1993. The reduction in the
gross profit percentage resulted from continued industry price competition and
increased sales to larger volume, lower margin customers, such as hospitals.
 
  Selling and administrative expenses and depreciation for 1994 were $149.1
million compared to $136.1 million for 1993, an increase of 9.5%. The cost
increases reflect inflationary increases and increases in warehouse and
delivery expenses which are variable with sales volume. Continued emphasis on
cost containment programs as well as the economies associated with the
significant revenue growth, reduced overall selling and administrative
expenses and depreciation as a percentage of revenues to 3.57% in 1994 from
3.72% in 1993.
 
  Operating expenses in 1994 include a provision of $4.1 million to cover the
expected environmental remediation costs at one of its former distribution
centers. In addition, in the third quarter of fiscal 1994, the Company
completed a detailed evaluation of the recovery of the recorded value of the
excess of cost over net
 
                                      10
<PAGE>
 
assets acquired ("goodwill") and concluded that projected operating results
would not support the future recovery of the remaining goodwill balance.
Accordingly, the Company wrote off the remaining goodwill balance of $179.8
million in the third quarter of fiscal 1994.
 
  Operating income, excluding unusual items and amortization, of $86.1 million
for fiscal 1994 increased 17.4% over fiscal 1993. As a percentage of revenues,
the Company's operating margin, excluding unusual items and amortization,
expanded to 2.06% in 1994 from 2.00% in 1993.
 
  Interest expense which is payable currently (cash interest), principally
related to the revolving credit facility and the senior subordinated notes,
was $43.7 million in 1994 as compared with $42.4 million in 1993, an increase
of 3.3%. The increase was as a result of higher interest rates on the
Company's variable rate borrowings offset in part by lower variable rate
borrowing levels and the reduction in principal amount of the senior
subordinated notes. Interest expense in 1994 reflects reductions as a result
of the purchase and retirement of an aggregate principal amount of $8.9
million of senior subordinated notes, which occurred during the fourth quarter
of fiscal 1993 and first quarter of fiscal 1994. Interest expense in 1994
includes $621,000 paid to the holders of an aggregate of $165.7 million in
principal amount of senior subordinated notes (see Note 5 of "Notes to
Consolidated Financial Statements"). During 1994, the average outstanding debt
level was $562 million at an average interest rate of 10.3%. In 1993, the
comparable average outstanding debt level was $551 million at an average
interest rate of 11.0%. The decrease in interest expense which is not
currently payable (pay-in-kind interest) of $5.5 million was due to the
refinancing in July 1993 of the 18% senior subordinated debentures, 18 1/2%
merger debentures, and 19 1/2% junior subordinated debentures with the 11 1/4%
senior debentures. Interest expense in 1994 includes $4.0 million in
amortization of financing fees as compared with $3.9 million in 1993.
 
  Income taxes provided in 1994 and 1993 have been determined based on the
alternative minimum tax system. As noted below, the Company changed its method
of accounting for income taxes effective October 1, 1993. The extraordinary
charge of $679,000, net of a tax benefit of $23,000, relates to the purchase
and retirement of an aggregate principal amount of $4.4 million senior
subordinated notes.
 
  Effective October 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 106, "Employers' Accounting for Postretirement
Benefits Other Than Pensions" (Statement 106) and Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" (Statement 109).
The Company recorded, as of October 1, 1993, a total of $34.6 million in
noncash charges to net income for the effects of transition to these two new
standards. The cumulative effect of the change in accounting for post
retirement benefits other than pensions resulted in a noncash charge to net
income of $1.2 million as of October 1, 1993. The cumulative effect of the
change in accounting for income taxes resulted in a noncash charge to net
income of $33.4 million as of October 1, 1993, principally related to the
provision of deferred income taxes to reflect the tax consequences on future
years of the difference between the tax and financial reporting bases of
merchandise inventories.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  During the fiscal-year ended September 30, 1995, the Company's operating
activities consumed $35.6 million in cash. The use of funds was primarily the
result of the increases in restricted cash, accounts and notes receivable, and
merchandise inventories, offset by an increase in accounts payable, accrued
expenses and income taxes. Restricted cash represents amounts temporarily
deposited in the Master Trust pursuant to the Receivables Program. The net
increase in other working capital items was the result of opening distribution
facilities in Springfield, Massachusetts, Portland, Oregon, and Sacramento,
California. Operating cash uses during the year ended September 30, 1995
included $43.6 million in interest payments and $2.8 million in income tax
payments.
 
  Subsequent to year-end, the Company opened new distribution facilities in
Phoenix, Arizona and Orlando, Florida. Capital expenditures for fiscal 1995
were $13.7 million and relate principally to the opening of the five new
distribution centers, continuing investments in management information
systems, and warehouse improvements. During fiscal 1995, the Company acquired
substantially all of the assets of LDS Liberty Drug Systems and Newbro Drug
Company for approximately $4.9 million. Liberty Drug Systems provides pharmacy
dispensing hardware and software systems in retail pharmacies. Newbro Drug
Company is a full-service
 
                                      11

wholesale pharmaceutical distributor in Idaho. The Company intends to continue
its investments in information systems and warehouse improvements and will
continue to evaluate acquisitions and other business opportunities.
 
  In December 1994, the Company sold substantially all of its receivables to
ARC, pursuant to the Receivables Program. Pursuant to the Receivables Program,
ARC will continuously transfer receivables to a master trust in exchange for,
among other things, Certificates representing a right to receive a variable
principal amount. Contemporaneous with the consummation of the Receivables
Program, the Company amended its existing Credit Agreement with its senior
lenders and redeemed in January 1995 all of the outstanding 14 1/2% senior
subordinated notes at a redemption price of 106% of the principal amount plus
accrued interest through the redemption date totaling $176.2 million. In April
1995, the Company completed an initial public offering with the issuance of
7,590,000 common shares at $21.00 per share, the net proceeds of which
(approximately $148.2 million) were used to redeem in May 1995 one-half of the
11 1/4% senior debentures outstanding for 110% of the principal amount plus
accrued interest through the date of redemption (approximately $84.4 million)
and to pay down the Company's revolving credit facility. As a result of the
public offering and the Company's financial results, the borrowing rate
alternatives under the Credit Agreement was reduced by 1.0% to LIBOR plus
1.25% and the prime rate plus zero beginning in October 1995. The Company also
incurred approximately $10.1 million in fees connected with the refinancings.
At September 30, 1995, borrowings under the Company's $380 million revolving
credit facility were $150 million (at an average interest rate of 7.6%) and
borrowings under the $285 million Receivables Program were $210 million (at an
average interest rate of 6.3%).
 
  An increase in interest rates would adversely affect the Company's operating
results and the cash flow available after debt service to fund operations and
any expansion and, if permitted to do so under its revolving credit facility,
to pay dividends on its capital stock.
 
  The Company's operating results have generated sufficient cash flows which,
together with borrowings under its debt agreements and credit terms from
suppliers, have provided sufficient capital resources to finance working
capital and cash operating requirements, fund capital expenditures, and
interest currently payable on outstanding debt. The Company's primary ongoing
cash requirements will be to fund payment of interest on indebtedness, finance
working capital, and fund capital expenditures and routine business growth and
expansion through new business opportunities. Future cash flows from
operations and borrowings under the debt agreements are expected to be
sufficient to fund the Company's ongoing cash requirements.
 
  The Company is subject to contingencies pursuant to environmental laws and
regulations at one of its former distribution centers that may require
remediation efforts. In fiscal 1994, the Company accrued a liability of $4.1
million to cover future consulting, legal and remediation, and ongoing
monitoring costs. The accrued liability, which is reflected in other long-term
liabilities on the accompanying consolidated balance sheet, is based on an
estimate of the extent of contamination and choice of remedy, existing
technology, and presently enacted laws and regulations, however, changes in
remediation standards, improvements in cleanup technology, and discovery of
additional information concerning the site could affect the estimated
liability in the future. The Company is investigating the possibility of
asserting claims against responsible parties for recovery of these costs.
Whether or not any recovery may be forthcoming is unknown at this time.
 
  In fiscal 1994, the Company concluded that the carrying value of goodwill
which was recorded at the time of the leveraged buyout transaction in 1988
("Acquisition") could not be recovered from expected future operations and
accordingly wrote-off its remaining goodwill balance of $179.8 million. In
1994, the Company determined its then poor operating results since the
Acquisition and its expectations for future operating results were being
adversely affected by its then current capital structure; price competition
for market share; health care industry consolidation; the impact of group
purchasing organizations; and health care reform on drug prices. As these
factors became clear, the Company assessed the recoverability of its goodwill
through projected operations. It was determined that unless the Company was
able to develop successful strategic operating or financing initiatives which
would change the assumptions used in those projections, those projections were
the best estimate of the Company's projected performance given the Company's
then existing high leverage and industry trends. More importantly, the
projections indicated that the Company's long-term viability required
modification of its then current capital structure to reduce indebtedness and
increase its equity.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.
 
               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
To the Board of Directors and Stockholders of
AmeriSource Health Corporation
 
  We have audited the accompanying consolidated balance sheets of AmeriSource
Health Corporation (formerly AmeriSource Distribution Corporation) and
subsidiaries as of September 30, 1995 and 1994, and the related consolidated
statements of operations, changes in stockholders' equity, and cash flows for
each of the three years in the period ended September 30, 1995. Our audits
also included the financial statement schedules listed in the Index at Item
14(a). These financial statements and schedules are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements and schedules based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and
schedules are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and schedules. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement and schedule presentation. We
believe that our audits provide a reasonable basis for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of AmeriSource Health Corporation and subsidiaries at September 30, 1995 and
1994 and the consolidated results of their operations and their cash flows for
each of the three years in the period ended September 30, 1995, in conformity
with generally accepted accounting principles. Also, in our opinion, the
related financial statement schedules, when considered in relation to the
basic financial statements taken as a whole, present fairly in all material
respects the information set forth therein.
 
  As discussed in notes 4 and 7 to the consolidated financial statements, in
1994 the Company changed its methods of accounting for income taxes and
postretirement benefits other than pensions.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                              SEPTEMBER 30, 1995
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Principles of Consolidation
 
  The accompanying consolidated financial statements include the accounts of
AmeriSource Health Corporation, formerly AmeriSource Distribution Corporation,
and its wholly-owned subsidiaries (the "Company") as of the dates and for the
periods indicated. All intercompany transactions and balances have been
eliminated in consolidation.
 
 Business
 
  The Company is a wholesale distributor of pharmaceuticals and related health
care products.
 
 Cash Equivalents
 
  The Company classifies highly liquid investments with original maturities of
three months or less at date of purchase as cash equivalents.
 
 Concentrations of Credit Risk
 
  The Company sells its merchandise inventories to a large number of customers
in the health care industry including independent drug stores, chain drug
stores, hospitals, mass merchandisers, clinics, and nursing homes. The
Company's trade accounts receivable are exposed to credit risk, however, the
risk is limited due to the diversity of the customer base and the customer
base's wide geographic dispersion. The Company performs ongoing credit
evaluations of its customers' financial condition. The Company maintains
reserves for potential bad debt losses and such bad debt losses have been
within the Company's expectations.
 
 Merchandise Inventories
 
  Inventories are stated at the lower of cost or market. Cost is determined
using the last-in, first-out (LIFO) method, which results in a matching of
current costs and revenues. On a supplemental basis, if the first-in, first-
out (FIFO) method of valuation had been used for determining costs,
inventories would have been approximately $93,803,000 and $88,327,000 higher
than the amounts reported at September 30, 1995 and 1994, respectively.
 
 Depreciation
 
  The cost of property and equipment is depreciated over the estimated useful
lives of the related assets by the straight-line method.
 
 Revenue Recognition
 
  The Company recognizes revenues when products are delivered to customers.
Additionally, the Company acts as an intermediary in the bulk shipment of
pharmaceuticals from manufacturers to customers' warehouses, which have been
excluded from revenues and totaled $107 million, $120 million, and $60 million
in fiscal years 1995, 1994, and 1993, respectively. The service fees earned
related to these bulk shipments are included in

revenues and were insignificant. Revenues and cost of goods sold in prior
years have been reclassified to conform with the 1995 presentation for bulk
shipments.
 
 Reclassifications
 
  Certain prior-year amounts have been reclassified to conform with the
current-year presentation.
 
 Earnings Per Share and Share Data
 
  Earnings (loss) per share is computed on the basis of the weighted average
number of shares of common stock outstanding during the periods presented
(18,295,000 for fiscal 1995 and 14,750,000 in fiscal 1994 and 1993) plus the
dilutive effect of stock options (38,000 and 101,000 for the fiscal 1995
primary and fully diluted calculations, respectively). Share and per share
amounts prior to April 1995 have been adjusted for the 2.95-for-1 stock split
effected in conjunction with the Company's public offering (see Note 6).
 
NOTE 2--ACQUISITIONS
 
  During fiscal 1995, the Company acquired substantially all of the assets of
Newbro Drug Company, a wholesale pharmaceutical distributor located in Idaho
Falls, Idaho and of Liberty Drug Systems, a North Carolina-based provider of
pharmacy software and hardware. The aggregate purchase price for these
acquisitions was approximately $4.9 million in cash, which approximated the
fair value of the net tangible assets acquired. These acquisitions were
accounted for by the purchase method and are included in the financial
statements from their dates of acquisition. The pro forma effects on the
Company's results of operations had these acquisitions occurred at the
beginning of the periods presented are not material.
 
NOTE 3--EXCESS OF COST OVER NET ASSETS ACQUIRED
 
  Excess of cost over net assets acquired ("goodwill") was recorded at the
time of the leveraged buyout transaction ("Acquisition") in 1988. As of June
30, 1994, the Company determined it was unable to achieve the operating
results projected at the time of the Acquisition. Since the Acquisition, the
Company has been affected by price competition for market share within the
industry, health care industry consolidation, and the impact of group
purchasing organizations, managed care, and health care reform on drug prices.
In fiscal 1994, the Company determined its then poor operating results since
the Acquisition and its expectations for future operating results were being
significantly affected by its then-current capital structure and fundamental
changes in the market place in which the Company operates. As these factors
became clear and in conjunction with the then recent increases in the interest
rates, a detailed comprehensive evaluation of the Company's future prospects
was prepared. The evaluation determined the Company's financial losses at that
time were significantly affected by its highly leveraged capital structure,
price sensitivity, aggressive pricing by better capitalized competitors,
consolidations in the wholesale drug distribution industry and the impact of
larger buying groups. Based on the then-current industry trends, interest rate
trends and the health care reform environment, in the third quarter of fiscal
1994, the Company concluded that the projected operating results ("the
Projection") would not support the future recovery of the remaining goodwill
balance.
 
  The methodology employed to assess the recoverability of the Company's
goodwill was to project results of operations forward 36 years, which
approximated the remaining amortization period of the goodwill balance at June
30, 1994. The Company then evaluated the recoverability of goodwill on the
basis of those Projections.
 
  It was determined that unless the Company was able to develop successful,
strategic, operating, or financing initiatives which would change the
assumptions used in the Projections, the projected future operating results
based on those assumptions was the best estimate of the Company's projected
performance given the Company's

NOTE 3--EXCESS OF COST OVER NET ASSETS ACQUIRED--(CONTINUED)
then-existing high leverage and industry trends. As a result, the Company
concluded that the carrying value of goodwill could not be recovered from
expected future operations. Accordingly, the Company wrote off its remaining
goodwill balance of $179.8 million in the third quarter of fiscal 1994. More
importantly, the Projection indicated that the Company's long-term viability
required modification of its then-current capital structure to reduce its
indebtedness and increase its equity.

  Effective October 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" (Statement 109),
which required a change in the method of accounting for income taxes from the
deferred method to the liability method. In accordance with Statement 109, the
Company recorded an adjustment of $33.4 million for the cumulative effect of
adopting Statement 109 as of October 1, 1993. As permitted under Statement
109, prior-period financial statements have not been restated. The cumulative
effect adjustment relates principally to the provision of deferred income
taxes to reflect the tax consequences on future years of the difference
between the tax and financial reporting basis of merchandise inventories.

  The valuation allowance for deferred tax assets was $17.6 million at October
1, 1993. For the fiscal years ended September 30, 1993, the deferred income
tax provision (benefit) resulted from timing differences in the recognition of
certain expenses for tax and financial reporting purposes. Due to limitations
on the utilization of tax losses, the Company did not recognize any deferred
income tax benefit in 1993. The principal components of deferred taxes in 1993
were as follows (in thousands):

  An unused federal tax net operating loss carryover of $37 million, which
will expire between 2008 and 2010 if not used, is available to offset future
taxable income. In 1995, tax benefits of $6.2 million related to the exercise
of employee stock options in connection with the Company's public offering of
common stock described in Note 6, were recorded as capital in excess of par
value. Additional tax benefits of approximately $13.9 million related to the
exercise of these stock options will be recorded to capital in excess of par
value when these tax benefits are realized by the Company.
 
  The Company was subject to the alternative minimum tax for the fiscal year
ended September 30, 1994. The alternative minimum tax is imposed at a 20% rate
on the Company's alternative minimum taxable income which is determined by
making statutory adjustments to the Company's regular taxable income. Net
operating loss carryforwards were used to offset up to 90% of the Company's
alternative minimum taxable income. The alternative minimum tax paid is
allowed as an indefinite credit carryover against the Company's regular tax

liability in the future when the Company's regular tax liability exceeds the
alternative minimum tax liability. As of September 30, 1995, the Company has a
$7 million alternative minimum tax credit carryforward.
 
  Income tax payments amounted to $2.8 million, $3.9 million, and $0.4 million
in the fiscal years ended September 30, 1995, 1994, and 1993, respectively.
 
NOTE 5--LONG-TERM DEBT
 
 Receivable Securitization Financing
 
  In December 1994, the Company sold substantially all of its trade accounts
and notes receivable (the "Receivables") to AmeriSource Receivables
Corporation ("ARC"), a special-purpose, wholly-owned subsidiary, pursuant to a
trade receivables securitization program (the "Receivables Program").
Contemporaneously, the Company entered into a Receivables Purchase Agreement
with ARC, whereby ARC agreed to purchase on a continuous basis Receivables
originated by the Company. Pursuant to the Receivables Program, ARC will
transfer such Receivables to a master trust in exchange for, among other
things, certain trade receivables-backed certificates (the "Certificates").
During the term of the Receivables Program, the cash generated by collections
on the Receivables will be used to purchase, among other things, additional
Receivables originated by the Company. Pursuant to the Receivables Program, on
December 13, 1994, the Company sold $305 million in Receivables to ARC in
exchange for cash and a subordinated note. ARC in turn transferred the
Receivables to the master trust for the Certificates and a residual interest
in the master trust. The Company has accounted for the transactions pursuant
to the terms of the Receivables Purchase Agreement as a sale of Receivables
from AmeriSource to ARC and as a financing transaction by ARC on the Company's
consolidated financial statements. The assets and liabilities of the master
trust have been consolidated with the Company at September 30, 1995.
 
  Pursuant to the Receivables Program, the Company issued: (i) $175 million of
Floating Rate Class A Trade Receivables Participation Certificates ("Class A
Certificates") and (ii) $35 million of Floating Rate Class B Trade Receivables
Participation Certificates ("Class B Certificates"), which represent
fractional undivided interests in the Receivables and other assets of the
master trust. The Class A Certificates bear interest at one month LIBOR plus
 .35% and the Class B Certificates, which are subordinated to the Class A
Certificates, bear interest at one month LIBOR plus .70%. The Company has
entered into two-year interest rate cap agreements, expiring in May 1997 which
specify that the one-month LIBOR base rate will not be greater than 7.50% with
respect to $175 million of Class A Certificate borrowings under the
Receivables Program. In addition, the Company issued Floating Rate Revolving
Principal Trade Receivables Participation Certificates ("Revolving
Certificates"), pursuant to which investors may purchase up to $75 million of
interests in the master trust, which Certificates will bear interest, at the
Company's option, at either LIBOR plus .35% or the federal funds rate plus
1.00%. The Revolving Certificates will rank pari passu in right of payment
with the Class A Certificates. There were no Revolving Certificates
outstanding at September 30, 1995. The expected final payment date of amounts
outstanding under the Receivables Program will be March 15, 2000, but earlier
termination could occur upon the occurrence of certain defined events. In the
event of a liquidation, losses on Receivables will first be absorbed by the
residual certificate held by ARC and collections on Receivables will first be
allocated to make payments of outstanding principal of the Certificates in
accordance with their ratable interests in the assets of the master trust,
after giving effect to the allocation of losses to the residual interest. Fees
of $4.6 million incurred in connection with establishing the Receivables
Program and interest rate cap agreements have been deferred and are being
amortized on a straight-line basis over a period of two to five years. Class A
Certificates of $175 million principal amount (at an interest rate of 6.2%)
and Class B Certificates of $35 million principal amount (at an interest rate
of 6.6%) were outstanding under the Receivables Program at September 30, 1995.

Company is required to pay a commitment fee of 1/4 of 1% per annum on the
average unused portion of the Certificates. Restricted cash of $14.6 million
at September 30, 1995, represents amounts temporarily deposited in the master
trust from collections on the Receivables, which are designated for specific
purposes pursuant to the Receivables Program.
 
 Revolving Credit Agreement
 
  In December 1994, the Company amended its existing credit agreement with a
syndicate of senior lenders providing a senior secured facility of $380
million (the "Credit Agreement"). Among other things, the amendment (i)
extended the term of the original credit agreement until January 3, 2000; (ii)
provided interest rate stepdowns upon the occurrence of certain events; (iii)
modified the borrowing base availability from inventory- and receivable-based
to inventory-based; and (iv) increased the Company's ability to make
acquisitions and pay dividends. An extraordinary loss of $3.4 million (less a
$1.0 million tax benefit) was recorded during the fiscal year ended September
30, 1995 representing the write-off of the unamortized financing fees relating
to the former revolving credit facility. In connection with the new revolving
credit facility, the Company incurred approximately $5.5 million in financing
fees which have been deferred and are being amortized on a straight-line basis
over the five-year term of the Credit Agreement. The maximum amount that may
be borrowed under the Credit Agreement is limited to the extent of a
sufficient borrowing base (up to a maximum of $380 million), which is
essentially 65% of eligible inventory in fiscal year 1995, 62.5% of eligible
inventory in fiscal year 1996, and 60% of eligible inventory thereafter.
 
  The Credit Agreement may be prepaid during its term, although such
indebtedness may be subsequently reborrowed. The indebtedness under the Credit
Agreement may be permanently repaid in full or reduced in part at any time at
the option of the Company, without premium or penalty, upon prior written
notice.
 
  At the Company's option, borrowings under the Credit Agreement bear interest
at a rate per annum determined as follows: (i) a LIBOR rate, plus an
applicable margin (1.75% at September 30, 1995); or (ii) the applicable prime
rate of interest plus an applicable margin (.50% at September 30, 1995).
Interest on loans under the Credit Agreement is payable quarterly or, if
earlier, at the end of the applicable interest period loan intervals. A
portion of the net proceeds from the initial public offering (see Note 6) were
used to pay down the Company's revolving credit facility. As a result of the
public offering, and the Company's performance in 1995, the borrowing rate
alternatives under the Credit Agreement was reduced to LIBOR plus 1.25% and
the Prime rate plus zero beginning in October 1995.
 
  Under the terms of the Credit Agreement, the Company granted the senior
lenders a perfected first priority security interest in substantially all of
the Company's assets (except accounts receivable and certain related assets),
including, without limitation, real property, fixed assets, equipment,
inventory, stock of subsidiaries, trademarks, and intangible assets, to secure
its borrowings under the Credit Agreement. The Company is required to pay a
commitment fee of 1/4 of 1% per annum on the average unused portion of the
Credit Agreement plus an annual administration fee. At September 30, 1995, the
$150 million outstanding under the Credit Agreement bore interest at the rate
of 7.6% per annum.
 
 Senior Subordinated Notes
 
  Contemporaneously with the consummation of the Receivables Program and the
execution of the Credit Agreement, the Company redeemed all of the outstanding
14 1/2% senior subordinated notes at a redemption price

 Senior Subordinated Notes--(continued)
 
of 106% of the principal amount plus accrued interest through the redemption
date. In connection with the redemption of the 14 1/2% senior subordinated
notes, the Company recorded an extraordinary charge of $12.1 million (less a
$3.4 million tax benefit) during the fiscal year ended September 30, 1995
relating to the write-off of unamortized deferred financing fees and premiums
paid on the redemption.
 
 Senior Debentures
 
  On July 26, 1993, the Company issued $126.5 million principal amount of 11
1/4% Senior Debentures ("Senior Debentures") due 2005 in a public offering.
Interest on the Senior Debentures is payable semiannually on January 15 and
July 15 of each year. Through and including the semiannual payment due July
15, 1998, the Company may elect, at its option, to issue additional Senior
Debentures in satisfaction of its interest payment obligations. The Senior
Debentures are senior unsecured obligations of the Company and rank pari passu
in right of payment with all senior borrowings of the Company and senior in
right of payment to all subordinated indebtedness of the Company. The Senior
Debentures are structurally subordinated to all indebtedness and other
obligations of the Company. Substantially all the net proceeds from the Senior
Debentures (approximately $122 million) were applied to redeem the 18% Senior
Subordinated Debentures, 18 1/2% Merger Debentures and 19 1/2% Junior
Subordinated Debentures of the Company. The debt refinancing resulted in an
extraordinary charge of $12.8 million during the fiscal year ended September
30, 1993 relating to the redemption of the Merger Debentures and the write-off
of deferred financing costs, net of a tax benefit of $3.2 million. In
connection with the Senior Debentures, the Company incurred approximately $5.1
million in financing fees which have been deferred and are being amortized
over the twelve-year life of the indebtedness. In conjunction with the initial
public offering, the Company, in May 1995, redeemed one-half of the Senior
Debentures outstanding for 110% of the principal amount plus accrued interest
through the date of redemption (approximately $84.4 million), which resulted
in an extraordinary charge of $9.6 million (less a $2.7 million tax benefit)
related to the write-off of unamortized deferred financing fees and premiums
paid on the redemption.
 
  The indentures governing the Receivables Program, the Credit Agreement, and
the Senior Debentures contain restrictions and covenants, as amended, which
include limitations on incurrence of additional indebtedness, prohibition of
indebtedness, restrictions on distributions and dividends to stockholders, the
repurchase of stock and the making of certain other restricted payments, the
issuance of preferred stock, the creation of certain liens, transactions with
subsidiaries and other affiliates, and certain corporate acts such as mergers,
consolidations, and the sale of substantially all assets. Additional covenants
require compliance with financial tests, including current ratio, leverage,
interest coverage ratio, fixed charge coverage, and maintenance of minimum net
worth.
 
  Interest paid on the above indebtedness during the fiscal years ended
September 30, 1995, 1994, and 1993 was $43.6 million, $46.1 million, and $39.7
million, respectively.
 
  Total amortization of financing fees and expenses (included in interest
expense) for the fiscal years ended September 30, 1995, 1994, and 1993 was
$2.5 million, $4.0 million, and $3.9 million, respectively.
 
  As of September 30, 1995, the Company's revolving credit facility and
receivables securitization financing had fair values that approximated their
carrying amounts. The fair value of the Senior Debentures was approximately
$81 million and was based on a quoted value from brokers of 108.5%.

NOTE 6--STOCKHOLDERS' EQUITY
 
  In April 1995, the Company issued 7,590,000 shares of Class A common stock
in a public offering at $21.00 per share. The net proceeds from the offering
of $148.2 million were used to reduce the Company's outstanding indebtedness
(see Note 5). On a pro forma basis, income and earnings per share before
extraordinary items for fiscal 1995 would have been $35.0 million and $1.57,
respectively, if the public offering had occurred on October 1, 1994. The pro
forma information assumes reduced interest expense and applicable income tax
adjustments resulting from the application of the net proceeds from the
offering and it assumes 22,271,936 shares of common stock outstanding for the
year. The pro forma information does not necessarily reflect the actual
results that would have occurred nor is it necessarily indicative of future
results. In conjunction with the public offering, the Company's Board of
Directors authorized a 2.95-for-1 stock split and, accordingly all references
to earnings per share and share data in these financial statements have been
restated to give effect to the stock split. Also, the Company eliminated all
authorized shares of preferred stock, increased the authorized number of
shares of Class A common stock to 50,000,000 and decreased the authorized
number of shares of Class B common stock to 15,000,000.
 
  The holders of the Class A common stock are entitled to one vote per share
on all matters on which holders of Class A common stock are entitled to vote.
The holders of the Class A common stock may elect at any time to convert any
or all such shares into the Class B common stock on a share-for-share basis
(but only to the extent that such record holder of Class A common stock shall
be deemed to be required to convert such Class A common stock into Class B
common stock pursuant to applicable law).
 
  The rights of holders of Class B and Class C common stock and holders of
Class A common stock are substantially identical and entitle the holders
thereof to the same rights, privileges, benefits, and notices, except that
holders of Class B and Class C common stock generally do not possess the right
to vote on any matters to be voted upon by the stockholders of the Company,
except as provided by law. Holders of Class B and Class C common stock may
elect at any time to convert any and all of such shares into Class A common
stock, on a share-for-share basis, to the extent the holder thereof is not
prohibited from owning additional voting securities by virtue of regulatory
restrictions.
 
  The Class C common stock is subject to substantial restrictions on transfer
and has certain registration and "take-along" rights. A share of Class C
common stock will automatically be converted into a share of Class A common
stock (a) immediately prior to its sale in a future public offering or (b) at
such time as such share of Class C common stock has been sold publicly in a
transaction that complies with maximum quantity limitations applicable to such
sale until on or about March 31, 1996. Once a share of Class C common stock
has been converted into Class A common stock, it will no longer be subject to
any restrictions on transfer nor will it be entitled to the benefits of
registration and take-along rights.
 
  During fiscal 1995, the Company issued 2,893,766 shares of Class A common
stock upon the exercise of stock options (see Note 8), purchased as treasury
stock 1,338,894 shares of Class B common stock from 399 Ventures Partners
Inc., a wholly-owned indirect subsidiary of Citicorp pursuant to a prior
agreement, and purchased as treasury stock 292,452 shares of Class A common
stock from option holders to enable the holders to satisfy certain minimum tax
withholding obligations. During fiscal 1994, 44,250 shares of Class A common
stock were purchased as treasury stock.
 
NOTE 7--PENSION AND OTHER BENEFIT PLANS
 
  The Company provides a benefit for the majority of its employees under
noncontributory defined benefit pension plans. For each employee, the benefits
are based on years of service and average compensation. Pension costs, which
are computed using the projected unit credit cost method, are funded on at
least the minimum amount required by government regulations.

  Plan assets at September 30, 1995 are invested principally in listed stocks,
corporate and government bonds, and cash equivalents.
 
  Additionally, the Company sponsors the Employee Investment Plan, a defined
contribution 401(k) plan, which covers salaried and certain hourly employees.
Eligible participants may contribute to the plan up to 2% to

6% of their regular compensation before taxes. The Company matches the
employee contributions in an amount equal to 50% of the participants'
contributions. An additional discretionary Company contribution in an amount
not to exceed 50% of the participants' contributions may also be made
depending upon the Company's performance. All contributions are invested at
the direction of the employee in one or more funds. Employer contributions
vest over a five-year period depending upon an employee's years of service.
Costs of the plan charged to expense for the fiscal years ended September 30,
1995, 1994, and 1993 amounted to $0.9 million, $1.1 million, and $0.8 million,
respectively.
 
  As a result of special termination benefit packages previously offered, the
Company provides medical, dental, and life insurance benefits to only a
limited number of retirees and their dependents. These benefit plans are
unfunded. Prior to October 1, 1993, the Company recognized the expenses for
these plans on the cash basis. Effective October 1, 1993, pursuant to
Statement of Financial Accounting Standards No. 106, "Employers' Accounting
for Postretirement Benefits Other Than Pensions" (Statement 106), the Company
recognized the accumulated obligation related to these benefits resulting in a
noncash charge to net income in 1994 of $1.2 million. The accumulated
postretirement benefit obligation was $1.2 million as of September 30, 1995.
The weighted average discount rate used in determining the accumulated
postretirement benefit obligations was 7.25% and 7.75% at September 30, 1995
and 1994, respectively. The annual expense for such benefits is not material.
 
NOTE 8--STOCK OPTION PLANS
 
  In fiscal 1989, the Company adopted the AmeriSource Health Corporation and
Subsidiaries Employee Stock Purchase Plan (the "Purchase Plan") to enable
certain members of management to participate in the equity ownership of the
Company. Pursuant to the Purchase Plan, management investors, on November 3,
1989, purchased options on 1,716,347 shares of the Company's Class A common
stock which were exercisable at $.34 per share. Through fiscal 1993, 184,744
options were extinguished. The remaining 1,531,603 options outstanding under
the Purchase Plan were exercised during fiscal 1995 in conjunction with the
Company's public offering. No further awards will be granted under the
Purchase Plan.
 
  In fiscal 1990, the Company adopted the Partners Stock Option Plan (the
"Partners Plan") to enable other employees of the Company to participate in
the equity ownership of the Company. On March 2, 1991, options to acquire
368,160 shares of Class A common stock were granted at an exercise price of
$.34 per share. The options under the Partners Plan became exercisable when
they vested on September 30, 1994. Through fiscal 1993, 28,320 options were
canceled. During fiscal 1995, 3,392 options were canceled, and the remaining
336,448 options were exercised. No further awards will be granted under the
Partners Plan.
 
  In fiscal 1992, the Company adopted the 1991 Stock Option Plan (the "1991
Option Plan") for the granting of nonqualified stock options to acquire up to
an aggregate of 1,069,375 shares of Class A common stock. The options were
granted to certain members of the Company's management at an exercise price of
$.34 per share on April 8, 1992. During fiscal 1994, 29,500 options were
extinguished. During fiscal 1995, 14,160 options were canceled and the
remaining 1,025,715 options outstanding under the 1991 Option Plan were
exercised in conjunction with the Company's public offering. No further awards
will be granted under the 1991 Option Plan.
 
  During fiscal 1995, the Company adopted the AmeriSource Health Corporation
1995 Stock Option Plan (the "1995 Option Plan"), which provides for the
granting of nonqualified stock options to acquire up to approximately 1.2
million shares of common stock to employees of the Company at a price not less
than the fair market value of the common stock on the date the option is
granted. The option terms and vesting periods are determined at the date of
grant by a committee of the Board of Directors. Options expire six years after
the date

of grant unless an earlier expiration date is set at the time of grant. During
fiscal 1995, 895,000 options were granted under the 1995 Option Plan at an
exercise price of $21.00 per share, and a 5-year vesting period; 7,500 options
were subsequently canceled, leaving 887,500 options outstanding at September
30, 1995, none of which were exercisable.
 
  During fiscal 1995, the Company also adopted the AmeriSource Health
Corporation Non-Employee Director Stock Option Plan (the "Directors Plan"),
which provides for the grant of stock options to the Company's nonemployee
directors. Under the Directors Plan, stock options are granted annually at the
fair market value of the Company's common stock on the date of grant. The
number of options so granted annually is fixed by the plan. Such options
become fully exercisable on the first anniversary of their respective grant,
except for the options under the initial grant, which are fully exercisable on
the third anniversary of the grant. The total number of shares to be issued
under the Directors Plan may not exceed 50,000 shares. During fiscal 1995, an
initial grant of options under this plan were granted to purchase 20,000
shares of common stock at $21.00 per share, all of which were outstanding and
none of which were exercisable at September 30, 1995.
 
NOTE 9--LEASES
 
  The costs of capital leases are included in property and equipment and the
obligations therefor in other debt. Related amortization is included in
depreciation. At September 30, 1995, future minimum payments totaling $31.2
million under noncancelable operating leases with remaining terms of more than
one fiscal year were due as follows: 1996--$7.8 million; 1997--$7.0 million;
1998--$5.2 million; 1999--$3.2 million; 2000--$2.2 million; and thereafter
(through 2009)--$5.8 million. In the normal course of business, operating
leases are generally renewed or replaced by other leases.
 
  Total rental expense was $7.6 million in fiscal 1995, $6.2 million in fiscal
1994, and $6.0 million in fiscal 1993.
 
NOTE 10--LEGAL MATTERS AND CONTINGENCIES
 
  In the ordinary course of its business, the Company becomes involved in
lawsuits, administrative proceedings, and governmental investigations,
including antitrust, environmental, product liability, and regulatory agency
and other matters. In some of these proceedings, plaintiffs may seek to
recover large and sometimes unspecified amounts and the matters may remain
unresolved for several years. On the basis of information furnished by counsel
and others, the Company does not believe that these matters, individually or
in the aggregate, will have a material adverse effect on its business or
financial condition.
 
  In November 1993, the Company, along with six other wholesale distributors
and twenty-four pharmaceutical manufacturers, were named as defendants in a
series of purported class action antitrust lawsuits alleging violations of
various antitrust laws associated with the chargeback pricing system.
Plaintiffs seek injunctive relief, treble damages, attorneys' fees, and costs.
In October 1994, the Company entered into a Judgement Sharing Agreement with
other wholesaler and pharmaceutical manufacturer defendants. Under the
Judgement Sharing Agreement (a) the manufacturer defendants agreed to
reimburse the wholesaler defendants for litigation costs incurred, up to an
aggregate of $9 million; and (b) if a judgement is entered into against both
manufacturers and wholesalers, the total exposure for joint and several
liability of the Company is limited to the lesser of 1% of such judgement or
$1 million. In addition, the Company has released any claims that it might
have had against the manufacturers for the claims presented by the plaintiffs
in these lawsuits. The Judgement Sharing Agreement covers the federal court
litigation as well as the cases which have been filed in various state courts.
The Company believes it has meritorious defenses to the claims asserted in
these lawsuits and intends to vigorously defend itself in all of these cases.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
NOTE 10--LEGAL MATTERS AND CONTINGENCIES--(CONTINUED)
 
  The Company is subject to contingencies pursuant to environmental laws and
regulations at one of its former distribution centers that may require the
Company to take remediation efforts. In fiscal 1994, the Company accrued $4.1
million to cover future consulting, legal, and remediation and ongoing
monitoring costs. The accrued liability, which is reflected in other long-term
liabilities on the accompanying consolidated balance sheet ($3.9 million at
September 30, 1995), is based on an engineering analysis prepared by outside
consultants and represents an estimate of the extent of contamination and
choice of remedy, existing technology and presently enacted laws and
regulations. However, changes in remediation standards, improvements in
cleanup technology and discovery of additional information concerning the site
could affect the estimated liability in the future. The Company is
investigating the possibility of asserting claims against responsible parties
for recovery of these costs. Whether or not any recovery may be forthcoming is
unknown at this time, although the Company intends to vigorously enforce its
rights and remedies.
 
  The Company has received notices from the Internal Revenue Service asserting
deficiencies in federal corporate income taxes for the Company's taxable years
1987 through 1991. The proposed adjustments indicate a net increase to taxable
income for these years of approximately $24 million and relate principally to
the deductibility of costs incurred with respect to the leveraged buyout
transaction which occurred in 1988. The Company has analyzed these matters
with tax counsel and believes it has meritorious defenses to the deficiencies
asserted by the Internal Revenue Service. The Company will contest the
asserted deficiencies through the administrative appeals process and, if
necessary, litigation. The Company believes that any amounts assessed will not
have a material effect on the financial statements of the Company.
 
NOTE 11--NONRECURRING CHARGES
 
  The nonrecurring charges in 1993 consisted of $1.3 million in losses on the
disposal of three warehouses and charges of $1.0 million for the write-down to
net realizable value of two additional warehouses no longer in operation which
were designated for sale.

                FOOTNOTES TO THE CONDENSED FINANCIAL STATEMENTS
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  The accompanying condensed financial statements present the financial
position, results of operations and cash flows of AmeriSource Health
Corporation (the "Company") as of the dates and for the periods indicated in
accordance with Rule 12-04 of Regulation S-X of the Securities Exchange Act of
the Securities and Exchange Commission and, accordingly do not include the
accounts of its wholly-owned subsidiaries. The Company's primary asset is its
investment in and receivables from AmeriSource Corporation which is a wholly-
owned subsidiary of the Company. Substantially all of the Company's operations
are transacted by AmeriSource Corporation. The ability of the Company to pay
its obligations depends on the operations of AmeriSource Corporation and its
ability to pay dividends to the Company.
 
  These condensed financial statements should be read in conjunction with the
Consolidated Financial Statements of AmeriSource Health Corporation and
Subsidiaries contained in Item 8 of this document for more information on
long-term debt, stockholders' equity and other disclosures.
 
NOTE 2--LONG-TERM DEBT
 
  In July 1993, the Company issued $126.5 million principal amount of 11 1/4%
Senior Debentures due in 2005. Interest on the Senior Debentures is payable
semiannually on January 15 and July 15 of each year. Through July 15, 1998,
the Company may elect, at its option, to issue Senior Debentures in
satisfaction of its interest payment obligations. The Senior Debentures are
structurally subordinated to all indebtedness and other obligations of the
Company. In connection with the Senior Debentures, the Company incurred
approximately $5.1 million in financing fees which have been deferred and are
being amortized over the twelve-year life of the indebtedness. In connection
with the initial public offering described below, the Company redeemed one-
half of the Senior Debentures outstanding which resulted in an extraordinary
charge of $9.6 million (less a $2.7 million tax benefit) related to the write-
off of unamortized deferred financing fees and premiums paid on redemption.
 
NOTE 3--STOCKHOLDERS' EQUITY
 
  In April 1995, the Company issued 7,590,000 shares of Class A common stock
in a public offering at $21.00 per share. The net proceeds from the offering
of $148.2 million (net of $1.3 million of issuance costs) were used to redeem
a portion of the Senior Debentures ($81.7 million) described above and the
remaining amounts were invested in AmeriSource Corporation, which were used to
reduce its indebtedness. In conjunction with the initial public offering, the
Company authorized a 2.95-for-1 stock split and, accordingly all references to
earnings per share and share data in these condensed financial statements have
been restated to give effect to the stock split.

               (iii) Conversion.
                     ----------

                    (A)  Class A Common Stock and Class B Common Stock.  Each 
                         ---------------------------------------------
record holder of Class A Common Stock will be entitled to convert any or all of 
such holder's Class A Common Stock into the same number of shares of Class B 
Common Stock (but only to the extent that such record holder of Class A Common 
Stock shall be deemed to be required to convert such Class A Common Stock into 
Class B Common Stock pursuant to applicable law), and each record holder of 
Class B Common Stock will be entitled to convert any or all of the shares of 
such holder's Class B Common Stock into the same number of shares of Class A 
Common Stock; provided, however, that at the time of conversion of shares of 
              --------  -------
Class B Common Stock into shares of Class A Common Stock such holder would be 
permitted, pursuant to applicable law, to hold the total number of shares of 
Class A Common Stock which he would hold after giving effect to such conversion.

                    Each conversion of shares of Class A Common Stock into 
shares of Class B Common Stock, or shares of Class B Common Stock into shares of
Class A Common Stock, as the case may be, will be effected by the surrender of
the certificate or certificates representing the shares to be converted at the
principal office of the Corporation at any time during normal business hours,
together with a written notice by the holder of such shares stating the number
of shares that any such holder desires to convert into the other class of Common
Stock. Such conversion will be deemed to have been effected as of the close of
business on the date on which such certificate or certificates have been
surrendered and such notice has been received by the Corporation, and at such
time the rights of such holder with respect to the converted class of Common
Stock will cease and the person or persons in whose name or names the
certificate or certificates for shares of the other class of Common Stock are to
be issued upon such conversion will be deemed to have become the holder or
holders of record of the shares of such other class of Common Stock represented
thereby. Promptly after such surrender and the receipt by the Corporation of the
written notice from the holder hereinbefore referred to, the Corporation will
issue and deliver in accordance with the surrendering holder's instructions the
certificate or certificates for the other class of Common

                                      -4-
<PAGE>
 
Stock issuable upon such conversion and a certificate representing any shares of
Common Stock which were represented by the certificate or certificates delivered
to the Corporation in connection with such conversion but which were not
converted. The issuance of certificates for the other class of Common Stock upon
conversion will be made without charge to the holder or holders of such shares
for any issuance tax (except stock transfer taxes) in respect thereof or other
cost incurred by the Corporation in connection with such conversion.

                    (B)  Class C Common Stock.  A share of Class C Common Stock 
                         --------------------
will automatically be converted into a share of Class A Common Stock (i) 
immediately prior to its sale in a Subsequent Public Offering; or (ii) at such 
time as such share of Class C Common Stock has been sold in a Public Sale after 
a Subsequent Public Offering, and in compliance with the maximum quantity 
limitations as set forth in paragraph 4(a)(iv)(C) hereof, if such maximum 
quantity limitations remain in effect.  On the date of such automatic 
conversion, all rights with respect to the Class C Common Stock so converted 
will terminate, except for the rights of the holders thereof, upon surrender of 
their certificate or certificates therefor, to receive certificates for an equal
number of shares of Class A Common Stock.

                    As soon as practical after the date of such automatic 
conversion, the holder of shares of Class C Common Stock so converted shall 
surrender to the Corporation the certificate or certificates representing the 
shares so converted, and thereafter the Corporation shall cause to be issued and
delivered to such holder a certificate for the number of shares of Class A 
Common Stock issuable upon such conversion in accordance with the provisions 
hereof.  All certificates evidencing shares of Class C Common Stock which are 
automatically converted into Class A Common Stock in accordance with the 
provisions hereof shall, from and after the dates such certificates are so 
converted, be deemed to have been retired and cancelled and the shares of Class 
C Common Stock represented thereby converted into Class A Common Stock for all 
purposes, notwithstanding the failure of the holder or holders thereof to 
surrender such certificates to the Corporation.  The Corporation may thereafter 
take such appropriate action as may be necessary to reduce the authorized shares
of Class C Common Stock accordingly.  Upon such automatic conversion of a share 
of Class C Common Stock into a share of Class A Common Stock, such share will no
longer be subject to any of the restrictions on transfer described herein.

("Amendment") is entered into among AMERISOURCE CORPORATION, a Delaware
corporation ("Borrower"), GENERAL ELECTRIC CAPITAL CORPORATION, a corporation
organized under the banking laws of the State of New York ("GE Capital"), Co-

other lenders thereunder (collectively, the "Lenders" and each, a "Lender"), GE
Capital and BANKERS TRUST COMPANY, a corporation organized under the banking
laws of the State of New York ("BTCo"), as managing agents, BTCo, as the issuing
lender, and GE Capital, as the administrative agent for Lenders (in such
capacity, "Agent"), as of September 30, 1995, with reference to the following
facts:

                                   RECITALS
                                   --------

     A.   Borrower, GE Capital, individually and in its capacities as a managing
agent and Agent, BTCo, individually and in its capacities as a managing agent
and the issuing lender, Co-Agents, and each of the other Lenders, have entered
into that certain Amended and Restated Credit Agreement dated as of December 13,
1994, as amended by that certain First Amendment to Credit Agreement dated as of
February 10, 1995 (as amended, the "Credit Agreement"), pursuant to which
Lenders agreed to make certain financial accommodations to or for the benefit of
Borrower upon the terms and conditions contained therein.  Unless otherwise

and subsections shall refer to sections or subsections of the Credit Agreement.

     B.   Under the Credit Agreement, certain adjustments to be made from time

to EBITDA Ratio to clarify an ambiguity regarding the calculation of such ratio,
and Lenders are willing to do so subject to the terms and conditions set forth
in this Amendment.

          NOW, THEREFORE, in consideration of the continued performance by
Borrower of its promises and obligations under the Credit Agreement and the
other Loan Documents, and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, Borrower and Lenders hereby

                    "Total Debt to EBITDA Ratio" shall mean, as of any date, the
          ratio of (i) the Average Total Debt on such date, to (ii) EBITDA for
          the most recent Rolling Period; provided, that, only for the purpose

          of the adjustments, if any, to be made to the Applicable Margin,
          Applicable Letter of Credit Fee Rate and Applicable Unused Line Fee
          Rate after the receipt of at least $100,000,000 in gross cash proceeds

          application of such proceeds of such sales or contributions as if such
          sales or contributions occurred on the first day of the relevant
          Rolling Period (it being understood that pro forma effect to the
          application of such proceeds will only be given to those Fiscal
          Quarters ending prior to the date of the actual receipt of proceeds of
          such sales or contributions and that no pro forma effect to the
          application of such proceeds will be given to those Fiscal Quarters
          ending after the date of the actual receipt of the proceeds of such
