                         INDEPENDENT AUDITORS' REPORT
 
The Stockholders and Board of Directors of McKesson Corporation:
 
  We have audited the accompanying consolidated balance sheets of McKesson
Corporation and subsidiaries as of March 31, 1998, 1997, and 1996, and the
related statements of consolidated income, consolidated stockholders' equity
and consolidated cash flows for the years then ended. These financial
statements are the responsibility of the Corporation's management. Our
responsibility is to express an opinion on these financial statements 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 are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of McKesson Corporation and
subsidiaries at March 31, 1998, 1997, and 1996, and the results of their
operations and their cash flows for the years then ended in conformity with
generally accepted accounting principles.

                                FINANCIAL NOTES
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
  The consolidated financial statements of McKesson Corporation (the "Company"
or "McKesson") include the financial statements of all majority-owned
companies, except those classified as discontinued operations. All significant
intercorporate amounts have been eliminated. Certain prior year amounts have
been reclassified to conform to the current year presentation.
 
  Within the United States and Canada, McKesson is the largest wholesale
distributor of ethical and proprietary drugs, medical-surgical supplies and
health and beauty care products. The Company is also engaged in the processing
and sale of bottled drinking water to homes and businesses and packaged water
through retail stores. The principal markets for the drug, medical-surgical
supplies and health and beauty care distribution businesses are chain and
independent drug stores, hospitals, alternate care sites, food stores and mass
merchandisers.
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires that management make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities as of the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
  Cash and Cash Equivalents include all highly liquid debt instruments
purchased with a maturity of three months or less at the date of acquisition.
 
  Marketable Securities Available for Sale are carried at fair value and the
net unrealized gains and losses computed in marking these securities to market
have been reported within stockholders' equity. At March 31, 1998, the fair
value approximated the amortized cost of these securities. The investments
mature on various dates through fiscal 1999.
 
  Inventories consist of merchandise held for resale and are stated at the
lower of cost or market. The majority of the cost of domestic inventories is
determined on the last-in, first-out (LIFO) method. International inventories
are stated at average cost.
 
  Property, Plant and Equipment is stated at cost and depreciated on the
straight-line method at rates designed to distribute the cost of properties
over estimated service lives ranging from one to 45 years.
 
  Capitalized Software included in other assets reflects costs related to
internally developed or purchased software for projects in excess of $1
million that are capitalized and amortized on a straight-line basis over
periods not exceeding seven years.
 
  Goodwill and Other Intangibles are amortized on a straight-line basis over
periods estimated to be benefited, generally 3 to 40 years. Negative goodwill
arising from the acquisition of the FoxMeyer business is being amortized over
a five year period (see Note 2). Accumulated amortization balances netted
against goodwill and other intangibles were $78.1 million, $61.2 million, and
$54.8 million at March 31, 1998, 1997 and 1996, respectively.
 
  Long-lived Assets. The Company periodically assesses the recoverability of
the cost of its long-lived assets, including goodwill, based on a review of
projected undiscounted cash flows associated with these assets. These cash
flows are prepared and reviewed by management in connection with the Company's
annual long range planning process. See Note 3 for charges the Company
recorded in fiscal 1997 related to impairment of assets.

                         FINANCIAL NOTES--(CONTINUED)
 
 
  Insurance Programs. Under the Company's insurance programs, coverage is
obtained for catastrophic exposures as well as those risks required to be
insured by law or contract. It is the policy of the Company to retain a
significant portion of certain losses related primarily to workers'
compensation, physical loss to property, business interruption resulting from
such loss, and comprehensive general, product, and vehicle liability.
Provisions for losses expected under these programs are recorded based upon
the Company's estimates of the aggregate liability for claims incurred. Such
estimates utilize certain actuarial assumptions followed in the insurance
industry.
 
  Revenue Recognition. Revenue is recognized when products are shipped or
services are provided to customers. Included in revenues are large volume
sales of pharmaceuticals to major self-warehousing drugstore chains whereby
the Company acts as an intermediary in the order and subsequent delivery of
products to the customers' warehouses. These sales totaled $2.7 billion in
1998, $2.8 billion in 1997 and $3.0 billion in 1996. Previously only the gross
margin from such sales had been classified in revenues. Such sales have been
reclassified into revenues and cost of sales for all periods presented. Also
included in revenues is interest income of $12.9 million, $14.5 million, and
$37.8 million in fiscal 1998, 1997 and 1996, respectively.
 
  Income Taxes. The Company accounts for income taxes under the liability
method in accordance with Statement of Financial Accounting Standards ("SFAS")
No. 109, "Accounting for Income Taxes", see Note 13.
 
  Foreign Currency Translation. Assets and liabilities of the Company's
foreign affiliates are translated at current exchange rates, while revenue and
expenses are translated at average rates prevailing during the year.
Translation adjustments related to the Company's Canadian operation are
reported as a component of stockholders' equity.
 
  The Company has a 23% equity interest in a pharmaceutical distributor in
Mexico, which has been designated a "highly inflationary economy" effective
January 1, 1997. Accordingly, adjustments associated with the translation of
this entity's financial statements have been reflected in the Company's
consolidated statement of income since that date. Prior to January 1, 1997,
translation adjustments associated with this entity were reported as a
component of stockholders' equity.
 
  Derivative Financial Instruments. The Company has entered into interest rate
and currency swap agreements to hedge certain interest and currency rate risks
which are accounted for using the settlement basis of accounting. As such, no
gains or losses are recorded for movements in the swaps' values during the
terms of the respective agreements.
 
  Employee Stock Options. The Company uses the intrinsic value method to
account for stock-based compensations in accordance with Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees." See Note 12
for the disclosures of pro forma earnings and earnings per share had the fair
value method been used to account for stock-based employee compensation plans
in accordance with SFAS No. 123, "Accounting for Stock-Based Compensation."
 
  Accounting Change. In fiscal 1998, the Company adopted SFAS No. 128
"Earnings per Share" which requires a dual presentation of basic and diluted
earnings per share ("EPS"). Basic EPS excludes dilution and is computed by
dividing net income available to common stockholders by the weighted average
number of common shares outstanding for the period. Diluted EPS reflects the
potential dilution that would occur if securities or other contracts to issue
common stock were exercised or converted into common stock. All share and per
share amounts have been restated in accordance with the provisions of SFAS No.
128. See Note 12.

  New Accounting Pronouncements. In fiscal 1998, the Financial Accounting
Standards Board issued SFAS No. 130 "Reporting Comprehensive Income," which
requires that an enterprise report, by major component and as a single total,
the change in its net assets during the period from nonowner sources; SFAS No.
131 "Disclosures about Segments of an Enterprise and Related Information, "
which establishes annual and interim reporting standards for an enterprise's
operating segments and related disclosures about its products, services,
geographic areas, and major customers; and SFAS No. 132 "Employers'
Disclosures about Pension and Other Postretirement Benefits," which
standardizes the disclosure requirements for pensions and other postretirement
benefits and expands disclosures on changes in benefit obligations and fair
values of plan assets. The Company plans to implement these statements in
fiscal 1999. Adoption of these statements will not impact the Company's
consolidated financial position, results of operations or cash flows, and any
effect will be limited to the form and content of its disclosures.
 
2. ACQUISITIONS, INVESTMENTS AND DIVESTITURES
 
  In August 1997, the Company's Canadian health care distribution business,
Medis Health and Pharmaceutical Services Inc. ("Medis") announced an agreement
with Drug Trading Company, Limited ("Drug Trading") to transition Drug
Trading's retail customers to Medis over a transition period. The Company
acquired assets consisting primarily of accounts receivable, inventories and
customer contracts, for approximately $83 million in cash. The transaction was
funded with proceeds from operations and short-term borrowings. This
acquisition was accounted for under the purchase accounting method and the
excess of the purchase price over the fair value of the net assets acquired of
$9.2 million is being amortized on a straight-line basis over 40 years. The
purchase price allocation is based on preliminary estimates and may be subject
to revision.
 
  In fiscal 1998, the Company also made a number of smaller acquisitions
including six distributors of first-aid products, two distributors of medical-
surgical supplies, and a pharmaceuticals distributor. The aggregate cost of
these acquisitions, accounted for as purchases, amounted to approximately
$20 million.
 
  On February 21, 1997, the Company acquired General Medical Inc. ("MGM") for
approximately $775 million including the issuance of approximately 5.6 million
shares of the Company's common stock and the assumption of approximately $428
million in debt. Payment of $30 million of the purchase price has been
withheld pending the outcome of a contingency. MGM is a multi-market
distributor of medical-surgical supplies to acute-care, physician-care, and
extended-care markets. This acquisition was accounted for under the purchase
method and the results of operations of MGM have been included in the
consolidated financial statements since the date of acquisition. The valuation
of the MGM net assets acquired included the recognition of liabilities
totaling $7.9 million related to closures of duplicate facilities and
involuntary termination and relocation benefits, of which $1.0 million and
$7.3 million remained outstanding as of March 31, 1998 and 1997, respectively.
Changes to the reserve in fiscal 1998 consisted primarily of cash payments for
severance benefits and costs to close down duplicate facilities. The excess of
the purchase price over the fair value of the net assets acquired of
approximately $600 million is being amortized on a straight-line basis over 40
years.
 
  On November 8, 1996, the Company acquired FoxMeyer Corporation's
pharmaceutical distribution business ("FoxMeyer"), pursuant to an expedited
auction process in the FoxMeyer Corporation bankruptcy proceeding in
Wilmington, Delaware. Through an amended sale agreement, the Company paid
approximately $23 million in cash to the debtors, paid off approximately $500
million in secured debt, and assumed an additional $75 million in other
liabilities. The Company utilized proceeds from commercial paper issuances and
a note payable to a bank to fund the transaction. The note payable
 
                                     
                                      10

to a bank was repaid prior to March 31, 1997, with cash flow from operations
and proceeds from divestitures. The Company acquired assets consisting
primarily of accounts receivable and inventories of approximately $650
million, customer contracts and fixed assets. This acquisition was accounted
for under the purchase method.
 
  As further discussed in Note 3, as a result of the FoxMeyer acquisition,
management assessed strategies and program offerings and initiated a plan to
optimize the network configuration from the combined distribution centers of
the Company and those acquired. This plan was reflected in the valuation of
the FoxMeyer net assets acquired. The plan to consolidate the FoxMeyer
business was developed and executed during the latter part of fiscal 1997 and
1998. Liabilities of $37.6 million were recognized for costs associated with
closures of duplicate distribution centers and workforce reductions of which
$3.0 million and $21.9 million remained outstanding as of March 31, 1998 and
1997, respectively. Reductions in the reserves in fiscal 1998 consisted
primarily of cash payments for severance benefits and costs related to
FoxMeyer facility closures. The excess of the fair value of net assets
acquired over the purchase price, after reducing to zero the carrying value of
long-term assets expected to be retained for use by the Company, was initially
estimated at $50 million (negative goodwill). In fiscal 1998, the estimates
were finalized resulting in a $22 million increase in goodwill (reduction in
negative goodwill) primarily for reserves for out of date and slow-moving
inventory at the acquisition date and additional liabilities assumed in the
transaction. The negative goodwill is being amortized over 5 years.
 
  The following unaudited pro forma information has been prepared assuming
FoxMeyer and MGM had been acquired as of the beginning of fiscal 1996:

  The unaudited pro forma information above is not indicative of the
consolidated financial position or results of operations of the Company as
they may be in the future or as they might have been had the MGM and FoxMeyer
acquisitions been effected on the assumed dates. For instance, due to
FoxMeyer's bankruptcy filing on August 27, 1996, and the resulting
deterioration in its operations through November 8, 1996, FoxMeyer experienced
a decline in its sales base, wrote off its goodwill and other intangibles
totaling $207.9 million, and established substantial accounts receivable and
inventory reserves and an additional valuation allowance for deferred tax
assets aggregating $153.4 million during the period from April 1, 1996 to
November 8, 1996.
 
  In April 1996, the Company acquired Automated Healthcare, Inc. ("MAH") for
$61.4 million in cash and the assumption of $3.2 million of employee stock
incentives. MAH designs, manufactures, sells, and installs automated
pharmaceutical dispensing equipment for use by health care institutions. The
acquisition was accounted for as a purchase and accordingly, MAH's results are
included in the consolidated financial statements since the date of
acquisition. The results of operations of MAH were not material in relation to
the Company's consolidated results of operations. The goodwill related to the
acquisition of approximately $13.4 million is being amortized on a straight-
line basis over a ten-year period. A $48.2 million charge was recorded to
write off the portion of the purchase price of MAH allocated to technology for
which technological feasibility had not been established as of the acquisition

date and for which there were no alternative uses. Existing technology was
valued at $0.4 million and is being amortized on a straight-line basis over a
three-year period. The Company utilized a discounted cash flow methodology by
product line to value in-process and existing technologies as of the
acquisition date.
 
  In fiscal 1996, the Company acquired McKesson BioServices, a provider of
support services to commercial, non-profit and governmental organizations
engaged in drug and biomedical development for $20 million. The Company also
acquired interests in two companies engaged in the development of new
technology-based initiatives to enhance the Health Care Services segment's
competitive position.
 
  On March 31, 1997, the Company sold its service merchandising unit,
Millbrook Distribution Services, Inc. ("Millbrook"), to R.A.B. Holdings, Inc.
The after-tax proceeds on the sale approximated Millbrook's book value.
 
  In March 1997, the Company sold its Aqua-Vend vended water business ("Aqua-
Vend"), a unit of the Water Products segment. The after-tax proceeds on the
sale approximated Aqua-Vend's book value, after giving effect to the $7.0
million pre-tax provision for impairment of certain assets recorded in the
third quarter of fiscal 1997; see Note 3.
 
  On December 31, 1996, the Company sold its 55% equity interest in Armor All
Products Corporation ("Armor All") to The Clorox Company for $221.9 million
and recognized an after-tax gain of $120.2 million. At closing, after-tax
proceeds of $109.8 million replaced the 6.9 million Armor All shares held in
trust as exchange property for the Company's $180 million exchangeable
subordinated debentures; see Note 8.
 
  All of the net assets and results of operations of both Armor All and
Millbrook have been reclassified as discontinued operations. Prior year
amounts have been restated.
 
  In fiscal 1996, the Company sold its interest in a Central American
pharmaceutical manufacturer for $36.1 million, resulting in a gain of $11.2
million.
 
3. CHARGES AND GAINS IN CONTINUING OPERATIONS
 
 Fiscal 1998
 
  On September 23, 1997, the Company and AmeriSource Health Corporation
("AmeriSource"), a leading U.S. wholesale distributor of pharmaceutical and
related health care products and services, jointly announced the execution of
a definitive Merger Agreement providing for the Company to acquire
AmeriSource. On March 3, 1998, the Federal Trade Commission voted to block the
proposed merger. On March 9, 1998, the FTC filed a complaint with the United
States District Court of the District of Columbia seeking a preliminary
injunction to halt the merger. On March 18, 1998, the Company and AmeriSource
each announced that they will oppose the FTC's motion for preliminary
injunction. A full hearing on the FTC's motion is expected to begin June 9,
1998. Although the merger and transactions contemplated thereby have been
approved by stockholders of both companies, there can be no assurance that
McKesson and AmeriSource will prevail in their opposition of the FTC's request
for a preliminary injunction, that the merger will be completed, or that it
will be completed as contemplated or what the results of the merger might be.
In light of this uncertainty, management deemed it appropriate to write off
transaction costs incurred to date of $16.7 million.
 
  In addition, the Company took a pre-tax charge of $10.5 million for costs
associated with the integration and rationalization of recent acquisitions
into the Company's operations including workforce
           
                                      12

                         FINANCIAL NOTES--(CONTINUED)
 
reductions designed to reduce cost structure. Approximately $9.4 million of
the $10.5 million charge is for severance and related benefits.
 
  The Company also incurred a charge of $3.4 million pre-tax in the Health
Care Services segment related primarily to the sale of an investment.
 
  The above discussed charges totaling $30.6 million, $25.4 million after-tax,
have been recorded in selling, distribution and administrative expenses. In
addition, the Company recognized a favorable one-time tax adjustment of $4.6
million associated with the completion of tax audits for certain prior years.
 
  The favorable tax adjustment was a non-cash transaction. There were no
significant changes in estimates or recharacterization of other amounts from
prior restructuring reserves in fiscal 1998.
 
Fiscal 1997
 
  The acquisition of the assets and operations of FoxMeyer (see Note 2)
resulted in a significant increase in sales volume, a substantial change in
the customer mix (primarily a large increase in institutional customers), and
overlapping, duplicate, and "similar purpose" assets. In fiscal 1997,
management reassessed the Company's operations, distribution center network
and business strategies, including program offerings in light of the FoxMeyer
acquisition. A plan was developed and executed during the latter part of
fiscal 1997 and fiscal 1998 to optimize the network configuration from the
combined distribution centers of the Company and those acquired in the
transaction which has resulted in the consolidation and closure of 15
distribution centers, workforce reductions, and disposal of excess, duplicate
assets. Management also reassessed strategies and program offerings for
expanding certain customer segments in light of the larger and more diverse
customer base and identified certain programs and investments, that would no
longer be pursued as originally contemplated. Other duplicate, common purpose
assets including administrative facilities, software, and other equipment were
reviewed to identify the optimum mix for the combined companies. This resulted
in the impairment in the value of certain assets which were not retained or
utilized as originally intended. The foregoing was reflected in the valuation
of the FoxMeyer assets acquired and liabilities assumed, and in the charges
discussed below with respect to the affected assets of the Company.
 
  The charges resulting from the impairment of assets of the Company as a
result of the integration and rationalization of the Company's distribution
operations, systems, strategies, and program offerings and administrative
functions, and for certain operating items were recorded in selling,
distribution, and administrative expenses and are summarized below:
 
<TABLE>

</TABLE>
 
  The write-downs associated with assets to be disposed of and asset
impairments due to changed business conditions were based primarily on
independent appraisals. Substantially all of the charges represented the
write-down of existing balances and were, accordingly, noncash. Balances

from a prior restructuring in fiscal 1995 for facilities closures were
considered in connection with the revised facilities plan after the FoxMeyer
transaction, resulting in an additional provision of $2.9 million. There were
no other significant changes in estimates or recharacterization of other
amounts from the prior restructuring reserves. Also included in the charge for
facilities closures was $7.2 million for Medis which had restructured its
distribution operations and network following a significant change in its
customer mix.
 
  The charge related to receivable reserves resulted from management's
reevaluation of the U.S. Health Care business' estimated exposures for bad
debts, disputed amounts, customer allowances, and rebates.
 
  Other operating items included a provision by the Water Products business of
$7.0 million for the impairment of assets in its vended water business. Other
operating items of the U.S. Health Care Services business consisted of $2.8
million of incremental costs incurred during a strike at a distribution
center, $1.5 million for the termination of a marketing program and certain
distributor relationships, and $5.0 million of other charges.
 
Summary of Reserve Balances
 
  The remaining balances outstanding for the combined reserves at March 31,
1998 and 1997 are as follows:

</TABLE>
 
  The disposition of properties in connection with facilities closures is
expected to be completed over the next one to two years. Charges to the
restructuring reserve in fiscal 1998, 1997 and 1996 consisted primarily of
asset write-offs (substantially all of which are non-cash) and cash payments
for severance of $1.7 million and asset holding costs of $1.9 million in
fiscal 1998, and for severance of $2.0 million and $5.2 million in fiscal 1997
and 1996, respectively.
 
4. OFF-BALANCE SHEET RISK AND CONCENTRATIONS OF CREDIT RISK
 
  Trade receivables subject the Company to a concentration of credit risk with
customers in the retail and institutional sectors. This risk is spread over a
large number of geographically dispersed customers.
 
  The Company sold $299.9 million and $147.4 million at March 31, 1998 and
1997, respectively, of trade receivables at amounts approximating their fair
value to a bank.
 
  Proceeds received by the Company on sales of accounts receivable with
recourse to the Company for certain uncollectible amounts totaled $105 million
in 1996.
 
  The Company's Canadian subsidiary, Medis, has agreements with certain of its
customers' financial institutions to repurchase inventory in the event the
customers are unable to meet certain obligations to the financial
institutions. Medis has also agreed to guarantee the payment of a major
customer's leases. The amounts related to these guarantees were approximately
$55.7 million for the inventory and $12 million for the lease obligations at
March 31, 1998.

  The Company has a revolving credit agreement with certain U.S. and Canadian
banks whereby the banks commit $250 million borrowing availability at the
reference rate (8.50% at March 31, 1998) or money market-based rates. The
agreement expires in fiscal 2002. The agreement permits the Company's wholly-
owned Canadian subsidiary, Medis, to borrow the Canadian dollar equivalent of
up to $75 million (as part of the $250 million arrangement) at the Canadian
prime rate or Canadian money market-based rates. The agreement contains
limitations on additional indebtedness. Compensating balances are not
required. The Company has additional available liquidity of $500 million for
general working capital purposes in the form of two facilities with a duration
of 364 days or less. At March 31, 1998, the Company had $750 million of unused
borrowing capacity under these agreements.
 
  Total interest payments were $94.4 million, $53.6 million, and $47.5 million
in fiscal 1998, 1997 and 1996, respectively.
 
  ESOP related debt (see Note 14) is payable to banks and insurance companies,
bears interest at rates ranging from 8.6% fixed rate to approximately 80% of
the prime or LIBOR +0.4% and is due in installments through 2009.
 
  In connection with the 4.5% exchangeable subordinated debentures, the March
31, 1998 marketable securities balance includes $76.7 million held in trust as
exchange property for the exchangeable subordinated debentures. The March 31,
1997 cash and cash equivalents and marketable securities balances include
$13.2 million and $96.6 million, respectively, held in trust as exchange
property for the exchangeable subordinated debentures. Through March 31, 1998,
the Company repurchased $66.7 million of the exchangeable subordinated
debentures.

  In fiscal 1998, the Company issued fixed rate, unsecured unsubordinated debt
totaling $300 million. The 6.3% notes mature on March 1, 2005 and the 6.4%
notes mature on March 1, 2008. In addition, a wholly-owned subsidiary of the
Company issued $125 million of 6.55% senior notes due November 1, 2002 which
are guaranteed by the Company.
 
  Certain debt agreements require that the Company's total debt not exceed
56.5% of total capitalization (total debt plus equity). At March 31, 1998, the
Company was in compliance with its debt covenants.
 
  In fiscal 1998, the Company entered into two interest rate swap agreements,
each with a notional principal amount of $150 million. The swaps mature in
2005 and 2008 and swap fixed interest payments of 6.30% and 6.40%,
respectively, for floating interest payments based on a LIBOR index; the
floating rates at March 31, 1998 were 4.92% and 4.82%, respectively. These
swaps have an imbedded interest rate cap of 7%.
 
  Also in fiscal 1998, a subsidiary of the Company entered into a currency
swap agreement to convert the $125 million proceeds from the issuance of
senior notes to $173 million Canadian currency, which was used to pay down
short-term borrowings of the Company's Canadian subsidiary, Medis. This swap
matures on November 1, 2002.

obligations (see Note 10) for the years ending March 31 are:

9. CONVERTIBLE PREFERRED SECURITIES
 
  In February 1997, a wholly-owned subsidiary trust of the Company issued 4
million shares of preferred securities to the public and 123,720 common
securities to the Company, which are convertible at the holder's option into
McKesson common stock. The proceeds of such issuances were invested by the
trust in $206,186,000 aggregate principal amount of the Company's 5%
Convertible Junior Subordinated Debentures due 2027 (the "Debentures"). The
Debentures represent the sole assets of the trust. The Debentures mature on
June 1, 2027, bear interest at the rate of 5%, payable quarterly and are
redeemable by the Company beginning in March 2000 at 103.5% of the principal
amount thereof.
 
  Holders of the securities are entitled to cumulative cash distributions at
an annual rate of 5% of the liquidation amount of $50 per security. Each
preferred security is convertible at the rate of 1.3418 shares of McKesson
common stock, subject to adjustment in certain circumstances. The preferred
securities will be redeemed upon repayment of the Debentures and are callable
by the Company at 103.5% of the liquidation amount beginning in March 2000.

  The Company has guaranteed, on a subordinated basis, distributions and other 
payments due on the preferred securities (the "Guarantee"). The Guarantee, when 
taken together with the Company's obligations under the Debentures and in the 
indenture pursuant to which the Debentures were issued and the Company's 
obligations under the Amended and Restated Declaration of Trust governing the 
subsidiary trust, provides a full and unconditional guarantee of amounts due on 
the preferred securities.
  
  The Debentures and related trust investment in the Debentures have been
eliminated in consolidation and the preferred securities reflected as
outstanding in the accompanying consolidated financial statements.

12. STOCKHOLDERS' EQUITY
 
  On October 29, 1997, the Company's board of directors declared a two-for-one
split of the Company's common stock. The split was effective January 2, 1998
for shareholders of record on December 1, 1997. All share and per share
amounts have been restated for the split.
 
  At March 31, 1998, 1997, and 1996, the Company was authorized to issue
100,000,000 shares of series preferred stock ($.01 par value) of which none
were outstanding and 200,000,000 shares of common stock ($.01 par value) of
which approximately 93,220,000 shares, 91,570,000 shares and 89,696,000 shares
were outstanding net of treasury stock, respectively.
 
  In October 1994, the Company's Board of Directors declared a dividend
distribution of one right (a "Right") for each then outstanding share of
common stock and authorized the issuance of one Right for each share
subsequently issued to purchase, upon the occurrence of certain specified
triggering events, a unit consisting of one one hundredth of a share of Series
A Junior Participating Preferred Stock. Triggering events include, without
limitation, the acquisition by another entity of 15% or more of the Company's
common stock without the prior approval of the Company's Board. The Rights
have certain anti-takeover effects and will cause substantial dilution to the
ownership interest of a person or group that attempts to acquire the Company
on terms not approved by the Board. The rights expire in 2004 unless redeemed
earlier by the Board. As a result of the two-for-one stock split described
above, each share of common stock now has attached to it one-half of a Right.
 
  The Company adopted SFAS No. 128, "Earnings per Share," in the third quarter
of the current fiscal year. All earnings and share amounts have been restated
in accordance with the provisions of SFAS No. 128.

  Pursuant to SFAS No. 123, the Company has elected to account for its stock-
based compensation plans under Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees." Accordingly, no compensation cost
has been recognized in the consolidated financial statements for the stock
option plans. Had compensation cost for the stock option plan been recognized
based on the fair value at the grant dates for awards under those plans,
consistent with the provision of SFAS No. 123, net income and earnings per
share would have been as indicated in the table below. Since pro forma
compensation cost relates to all periods over which the awards vest, the
initial impact on pro forma net income may not be representative of
compensation cost in subsequent years, when the effect of amortization of
multiple awards would be reflected.

14. POSTRETIREMENT AND POSTEMPLOYMENT BENEFITS
 
Pension Plans
 
  On December 31, 1996, substantially all full-time employees of the Company
were covered under either the Company-sponsored defined benefit retirement
plan or by bargaining unit sponsored multi-employer plans. On that date, the
Company amended the Company-sponsored defined benefit plan to freeze all plan
benefits based on each employee's plan compensation and creditable service
accrued to that date. The benefits for such Company-sponsored plans are based
primarily on age of employees at date of retirement, years of service and
employees' pay during the five years prior to employment.

On January 1, 1997, the Company amended the ESOP to provide future additional
benefits in place of a portion of those benefits previously provided by the
pension plan.
 
  Net pension expense (income) for the Company-sponsored defined benefit
retirement plan and executive supplemental retirement plan consisted of the

  The projected unit credit method is utilized for measuring net periodic
pension cost over the employees' service life. Costs are funded based on the
recommendations of independent actuaries. The projected benefit obligations
for Company-sponsored plans were determined using a discount rate of 7.25% at
December 31, 1997, 7.75% at December 31, 1996 and 7.25% at December 31, 1995
and an assumed increase in future compensation levels of 4.0% at December 31,
1995. The expected long-term rate of return on assets used to determine
pension expense was 9.75% for all periods. The adjustment required to
recognize the minimum liability at December 31, 1995 was charged to other
equity, net of tax, and was reversed at December 31, 1996.
 
  The assets of the plan consist primarily of listed common stocks and bonds
for which fair value is determined based on quoted market prices.

  The projected benefit obligation for the Company's executive supplemental
retirement plan at December 31, 1997 was $35.6 million of which $33.8 million
(the accumulated benefit obligation) is recognized as a liability on the
consolidated balance sheet.
 
 Profit-Sharing Investment Plan
 
  Retirement benefits for employees not covered by collective bargaining
arrangements include a supplementary contributory profit sharing investment
plan ("PSIP"). The leveraged ESOP portion of the PSIP has purchased an
aggregate of 24.3 million shares of common stock since inception. These
purchases have been financed by 10 to 20-year loans from or guaranteed by the
Company. The Company's related receivables from the ESOP have been classified
as a reduction of stockholders' equity. The loans will be repaid by the ESOP
from common dividends on shares not yet allocated to participants, interest
earnings on cash balances not yet allocated to participants, common dividends
on certain allocated shares and future Company cash contributions. The ESOP
loan maturities and rates are identical to the terms of related Company
borrowings (see Note 8).
 
  After-tax ESOP expense (income), including interest expense on ESOP debt,
was $(0.1) million, $2.3 million, and $(0.2) million in fiscal 1998, 1997 and
1996, respectively. Additional tax benefits received on dividends paid on
unallocated shares of $2.4 million, $3.1 million, and $2.2 million in fiscal
1998, 1997 and 1996, respectively, have been credited directly to retained
earnings in accordance with SFAS No. 109.
 
  Contribution expense for the PSIP in fiscal 1997, 1996 and 1995 was all ESOP
related and is reflected in the amounts above. In fiscal 1998, 1997 and 1996
approximately 694,000, 907,000 and 915,000 shares, respectively, were
allocated to plan participants.
 
  Through March 31, 1998, 11.3 million common shares have been allocated to
plan participants. At March 31, 1998, 13.0 million common shares in the ESOP
Trust had not been allocated to plan participants.
 
 Health Care and Life Insurance
 
  In addition to providing pension benefits, the Company provides health care
and life insurance benefits for certain retired employees. The Company's
policy is to fund these benefits as claims are paid. The benefits have been
reduced significantly for those employees retiring after December 31, 1990. In
1989, the Company implemented an ESOP to provide funds at retirement that
could be used for medical costs or health care coverage.
 
  Expenses for postretirement health care and life insurance benefits
consisted of the following:

  The assumed health care cost trend rate used in measuring the accumulated
postretirement benefit obligation is 6.0% for 1998, decreasing to 5.33% in
1999 and to an ultimate rate of 5.0% thereafter. The health care cost trend
rate assumption has a significant effect on the amounts reported. Increasing
the trend rate by one percentage point would increase the accumulated
postretirement health care and life insurance obligation as of March 31, 1998
by $7.2 million and the related fiscal 1998 aggregate service and interest
costs by $0.7 million. The discount rate used in determining the accumulated
postretirement benefit obligation was 7.25% at March 31, 1998, 7.75% at March
31, 1997 and 7.25% at March 31, 1996.

16. OTHER COMMITMENTS AND CONTINGENT LIABILITIES
 
  In addition to commitments and obligations in the ordinary course of
business, the Company is subject to various claims, other pending and
potential legal actions for product liability and other damages,
investigations relating to governmental laws and regulations, and other
matters arising out of the normal conduct of the Company's business.
 
  The Company currently is a defendant in numerous civil antitrust actions
filed since 1993 in federal and state courts by retail pharmacies. The federal
cases have been coordinated for pretrial purposes in the United States
District Court in the Northern District of Illinois and are known as MDL 997.
MDL 997 consists of a consolidated class action (the "Federal Class Action")
as well as approximately 109 additional actions brought by approximately 3,500
individual retail, chain and supermarket pharmacies (the "Individual
Actions"). There are numerous other defendants in these actions including
several pharmaceutical manufacturers and several other wholesale distributors.
These cases allege, in essence, that the defendants have violated the Sherman
Act by conspiring to fix the prices of brand name pharmaceuticals sold to
plaintiffs at artificially high, and non-competitive levels, especially as
 
                                      
                                      29

                         FINANCIAL NOTES--(CONTINUED)
 
compared with the prices charged to mail order pharmacies, managed care
organizations and other institutional buyers. A class has been certified in
the Federal Class Action. The Seventh Circuit Court of Appeals reversed the
District Court's grant of summary judgment in favor of the Company and the
other wholesale distributors in the Federal Class Action. Trial of the Federal
Class Action is currently scheduled to begin on September 14, 1998. The
Individual Actions will remain in the Northern District of Illinois for pre-
trial purposes, but will be remanded to their original transferor
jurisdictions for trial.
 
  The currently pending state court antitrust cases against the Company are in
California, Alabama and Mississippi. The Company has been dismissed pursuant
to a settlement in cases which were pending in Wisconsin (K-S Pharmacy, et al.
v. Abbott Laboratories, et al.) and Minnesota (Salk Drug v. Abbott
Laboratories, et al.). The state cases are based essentially on the same facts
alleged in the Federal Class Action and Individual Actions and assert
violations of state antitrust and/or unfair competition laws. The case in
California (referred to as Coordinated Special Proceeding, Pharmaceutical
Cases I, II & III) is pending in Superior Court for the State of California
(San Francisco County). A class of retail pharmacies has been certified and
the case is trailing MDL 997. The case in Alabama (Durrett, et al. v. The
Upjohn Co. et al.) is venued in the Circuit Court for Greene County, Alabama.
A class has not yet been certified, and the case is currently before the
Alabama Supreme Court on an appeal from the denial of defendants' motion to
dismiss. The case in Mississippi (Montgomery Drug Co. et al. v. The Upjohn Co.
et al.) is pending in the Chancery Court of Prentiss County, Mississippi. The
Chancery Court has held that the case may not be maintained as a class action.
 
  In each of the cases, plaintiffs seek remedies in the form of injunctive
relief and unquantified monetary damages, and attorneys fees and costs.
Plaintiffs in the California cases also seek restitution. In addition, trebled
damages are sought in the Federal Class Action, the Individual Actions and the
California case and statutory penalties of $500 per violation are sought in
the Mississippi and Alabama cases. The Company believes it has meritorious
defenses to the allegations made against it and intends to vigorously defend
itself in all of these actions. In addition, the Company has entered into a
judgment sharing agreement with certain pharmaceutical manufacturer
defendants, which provides generally that the Company (together with the other
wholesale distributor defendants) will be held harmless by such pharmaceutical
manufacturer defendants and will be indemnified against the costs of adverse
judgments, if any, against the wholesaler and manufacturers in these or
similar actions, in excess of $1 million in the aggregate per wholesale
distributor defendant.
 
  In January 1997, the Company and twelve pharmaceutical manufacturers (the
"Manufacturer Defendants") were named as defendants in the matter of FoxMeyer
Health Corporation vs. McKesson Corporation, et. al. filed in the District
Court in Dallas County, Texas. In its complaint, Plaintiff (the parent
corporation of FoxMeyer Drug Company and FoxMeyer Corporation collectively,
"FoxMeyer Corporation") alleges that, among other things, the Company (i)
defrauded Plaintiff, (ii) competed unfairly and tortiously interfered with
FoxMeyer Corporation's business operations, and (iii) conspired with the
Manufacturer Defendants, all in order to destroy FoxMeyer Corporation's
business, restrain trade and monopolize the marketplace, and allow the Company
to purchase that business at a distressed price. Plaintiff seeks relief
against all defendants in the form of compensatory damages of at least $400
million, punitive damages, attorneys fees and costs. The Company answered the
complaint, denying the allegations, and removed the case to federal bankruptcy
court in Dallas (the "Texas Action").
 
  In March 1997, the Company and the Manufacturer Defendants filed a complaint
in intervention against Plaintiff (now known as Avatex Corporation) in the
action filed against Avatex by the FoxMeyer Unsecured Creditors Committee in
the United States Bankruptcy Court for the District of Delaware. The complaint
in intervention seeks declaratory relief and an order enjoining Avatex from
pursuing the
 
                                     
                                      30

                         FINANCIAL NOTES--(CONTINUED)
 
Texas Action. Motions for summary judgment filed by the Company, the
Manufacturer Defendants and the Chapter 7 trustee in the Delaware action are
pending, as is a motion by Avatex to transfer the complaint in intervention to
the Texas Bankruptcy Court. In August 1997, the Texas Bankruptcy Court entered
an order denying the defendants' motion to transfer the case to the District
of Delaware and deferred ruling on the plaintiff's motion to demand the case
to the Texas State Court until the bankruptcy court in Delaware has ruled on
the motions for the summary judgment. The Company believes it has meritorious
defenses to the allegations made against it and intends to vigorously defend
this litigation.
 
  In July 1995, a purported class action was filed in the Supreme Court of the
State of New York against General Medical Corp., Inc. (also known as McKesson
General Medical) and several other defendants by Richard A. Bernstein,
Chairman and President of Rabco Health Services, Inc. and Chairman of General
Medical at the time of its leveraged buyout in 1993. Plaintiff alleges a
conspiracy to orchestrate the buyout of plaintiff's interest in Rabco at an
unfairly low price. Plaintiff alleges common law fraud, breach of fiduciary
duty and inducing breach of fiduciary duty. Plaintiff seeks rescissionary
damages of $50 million, compensatory damages of $25 million, and punitive
damages of $25 million. The complaint was initially dismissed with prejudice
by the Court but that order was reversed by the Court's Appellate Division.
Defendants thereupon filed their answers to the complaint together with a
motion for leave to appeal to the Court of Appeals, which motion was denied. A
renewed motion by defendants General Medical and GM Holdings to dismiss and/or
for summary judgment is pending. The Company believes it has meritorious
defenses to the allegations made against it and intends to vigorously defend
the action.
 
  The Company has been named along with several other defendants in two
lawsuits in California, Royer v. Wyeth-Ayerst Laboratories, et al. and
Valentine v. Wyeth-Ayerst Laboratories, et al., alleging that the plaintiffs
have been injured because they took the drugs fenfluramine or dexfenfluramine
with phentermine, commonly known as dexfen-phen or fen-phen. The Company has
tendered the cases to manufacturers of the drugs and has filed an answer in
one of the cases pending a reply. In addition, a third fen-phen case, Galvan
v. American Home Products, et al., filed in New York state court against a
customer of the Company, has been tendered to the Company by the customer.
This case is being defended by counsel retained by the Company to protect the
customer's interest pending the determination of tender to the manufacturers.
 
  Primarily as a result of the operation of its former chemical businesses,
which were divested in fiscal 1987, the Company is involved in various matters
pursuant to environmental laws and regulations:
 
  The Company has received claims and demands from governmental agencies
relating to investigative and remedial action purportedly required to address
environmental conditions alleged to exist at five sites where the Company (or
entities acquired by the Company) formerly conducted operations; and the
Company, by administrative order or otherwise, has agreed to take certain
actions at those sites, including soil and groundwater remediation.
 
  The current estimate (determined by the Company's environmental staff, in
consultation with outside environmental specialists and counsel) of the upper
limit of the Company's range of reasonably possible remediation costs for
these five sites is approximately $19 million, net of approximately $4 million
which third parties have agreed to pay in settlement or which the Company
expects, based on either on agreements or nonrefundable contributions which
are ongoing, to be contributed by third parties. The $19 million is expected
to be paid out between April 1998 and March 2028 and is included in the
Company's recorded environmental reserves at March 31, 1998.

<PAGE>
 
                         FINANCIAL NOTES--(CONTINUED)
 
  In addition, the Company has been designated as a potentially responsible
party (PRP) by the U.S. Environmental Protection Agency under the
Comprehensive Environmental Response Compensation and Liability Act of 1980,
as amended (the "Superfund" law), for environmental assessment and cleanup
costs as the result of the Company's alleged disposal of hazardous substances
at 18 Superfund sites. With respect to each of these Superfund sites, numerous
other PRP's have similarly been designated and while the current state of the
law potentially imposes joint and several liability upon PRPs, as a practical
matter costs of these sites are typically shared with other PRPs. The
Company's estimated liability at those 18 Superfund sites is approximately $1
million, net of $2 million which insurance companies, and $2 million which
another PRP, are expected or have agreed to contribute to the Company's
allocated share. The aggregate settlements and costs paid by the Company in
Superfund matters to date has not been significant. The $1 million is included
in the Company's recorded environmental reserves at March 31, 1998.
 
  The potential costs to the Company related to environmental matters is
uncertain due to such factors as: the unknown magnitude of possible pollution
and cleanup costs; the complexity and evolving nature of governmental laws and
regulations and their interpretations; the timing, varying costs and
effectiveness of alternate cleanup technologies; the determination of the
Company's liability of proportion to other PRPs; and the extent, if any, to
which such costs are recoverable from insurance or other parties.
 
  Management believes, based on current knowledge and the advice of the
Company's counsel, that the outcome of the litigation and governmental
proceedings discussed in this note will not have a material adverse effect on
the Company's financial position or results of operations.
