                                PROXY STATEMENT

GENERAL INFORMATION

PROXIES AND VOTING AT THE MEETING

The Company's Board of Directors is soliciting proxies to be voted at the Annual
Meeting of Stockholders to be held July 25, 2001 (the "Meeting"). This proxy
statement includes information about the issues to be voted upon at the Meeting.

On June 13, 2001, the Company began mailing these proxy materials to all
stockholders of record at the close of business on May 25, 2001. On this date,
there were approximately 284,974,625 shares of the Company's common stock
outstanding and entitled to vote. Each share is entitled to one vote on each
matter properly brought before the Meeting.

Shares can be voted only if the stockholder is present at the Meeting in person
or by proxy. Any person giving a proxy may revoke it at any time before the
Meeting by sending in a written revocation or a proxy bearing a later date.
Stockholders may also revoke their proxies by attending the Meeting in person
and casting a ballot.

Stockholders of record and participants in the Company's Profit-Sharing
Investment Plan ("PSIP") can give proxies by calling a toll free number, by
using the Internet, or by mailing their signed proxy cards. Specific
instructions for voting by means of the telephone or Internet are set forth on
the enclosed proxy card. All shares represented by valid proxies will be voted
as specified. If no specification is made, the proxies will be voted "FOR":

1. The election of three directors to three year terms;

2. Approving an amendment to the 1997 Non-Employee Directors' Equity
   Compensation and Deferral Plan to increase the number of shares available
   under the Plan;

3. Approving an amendment to the Company's Restated Certificate of Incorporation
   to change the Company's name to "McKesson Corporation";

4. Ratifying the appointment of Deloitte & Touche LLP as the Company's
   independent auditors for the fiscal year ending March 31, 2002;

and "AGAINST":

5. The stockholder proposal regarding performance-based options;

6. The stockholder proposal regarding a limitation on severance payments;

7. The stockholder proposal regarding the sale of the Company.

If other matters properly come before the Meeting, all shares validly
represented by proxies will be voted in accordance with the recommendations of
the Board.

PROXY MATERIALS AND ANNUAL REPORT

The Company's Notice of Annual Meeting and Proxy Statement is available on the
Company's website under the Investor Resource tab on the Internet at
www.mckhboc.com.

The Company's Annual Report on Form 10-K for the fiscal year ended March 31,
2001 ("FY 2001") accompanies these proxy materials and can also be found on the
Company's website.

ATTENDANCE AT THE MEETING

If you plan to attend the Meeting, you will need to bring your admission ticket.
You will find an admission ticket attached to the proxy card if you are a
registered holder or PSIP participant. If your shares are held in the name of a
bank, broker or other holder of record and you plan to attend the
   5

Meeting in person, you may obtain an admission ticket in advance by sending a
request, along with proof of ownership, such as a bank or brokerage account
statement, to the Company's Corporate Secretary, One Post Street, San Francisco,
California 94104. Stockholders who do not have an admission ticket will only be
admitted upon verification of ownership at the door.

DIVIDEND REINVESTMENT PLAN

For those stockholders who participate in the Company's Automatic Dividend
Reinvestment Plan, the enclosed proxy includes all full shares of common stock
held in the stockholder's dividend reinvestment plan account on the record date
for the Meeting, as well as shares held of record by the stockholder.

VOTE REQUIRED AND METHOD OF COUNTING VOTES

The presence in person or by proxy of holders of a majority of the outstanding
shares of common stock entitled to vote will constitute a quorum for the
transaction of business at the Meeting. Provided a quorum is present, directors
will be elected by a plurality of the votes cast by the holders of the Company's
shares of common stock voting in person or by proxy at the Meeting. The
affirmative vote of the holders of the majority of the shares present or
represented by proxy is required for the approval of the Amendment to the 1997
Non-Employee Directors' Equity Compensation and Deferral Plan, the ratification
of the appointment of Deloitte & Touche LLP and each of the stockholder
proposals. Abstentions for these matters will be treated as votes cast on a
particular matter as well as shares present and represented for purposes of
establishing a quorum. Broker nonvotes (i.e., when a broker does not have the
authority to vote on a specific issue) will not be treated as votes cast on any
of these matters, but will be treated as shares present or represented for
purposes of establishing a quorum. The affirmative vote of the holders of a
majority of the outstanding shares of common stock is required to approve the
proposal to amend the Company's Restated Certificate of Incorporation to change
the Company's name to McKesson Corporation. Accordingly, abstentions and broker
nonvotes will have the same effect as a negative vote.

PROFIT-SHARING INVESTMENT PLAN

Participants in the Company's PSIP have the right to instruct the PSIP Trustee,
on a confidential basis, how the shares allocated to their accounts are to be
voted and will receive a separate PSIP voting instruction card for that purpose.
Shares that have been allocated to PSIP participants' PAYSOP accounts for which
no voting instructions are received will not be voted. The PSIP provides that
all other shares for which no voting instructions are received from participants
and unallocated shares of common stock held in the leveraged employee stock
ownership plan established as part of the PSIP, will be voted by the Trustee in
the same proportion as shares as to which voting instructions are received.

DIRECTOR COMPENSATION

The compensation for each non-employee director of the Company includes an
annual retainer of $27,500. Under the 1997 Non-Employee Directors' Equity
Compensation and Deferral Plan, each director is required to defer 50% of his or
her annual retainer into either Restricted Stock Units ("RSUs") or Nonqualified
Stock Options ("Options"). Each director may also defer the remaining 50% of the
annual retainer into RSUs, Options or into the Company's deferred compensation
plan ("DCAP II"). Directors may also elect to receive cash. Directors also
receive $1,000 for each Board or Committee meeting attended, and Committee
chairs also receive an annual retainer of $3,000. These fees may be deferred
into RSUs or DCAP II or may be paid in cash. Directors are also paid their
reasonable expenses for attending Board and Committee meetings. See Item 2.
Proposal to Amend the 1997 Non-Employee Directors' Equity Compensation and
Deferral Plan.

Each January, directors are also granted an Option for 10,000 shares of the
Company's common stock. The Options are granted at fair market value, are
immediately exercisable, and have a term of ten years.

Directors who are employees of the Company or its subsidiaries do not receive
any compensation for service on the Board.

INDEMNITY AGREEMENTS

The Company has entered into indemnity agreements with each of its directors and
executive officers that provide for indemnification against any judgment or
costs assessed against them in the course of their service. Such agreements do
not permit indemnification for acts or omissions for which indemnification is
not permitted under Delaware law. See Certain Legal Proceedings at page 23.

REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

The Corporation's executive compensation program is administered by the
Compensation Committee (the "Committee") of the Board of Directors, which
consists exclusively of nonemployee directors. The Committee uses a nationally
recognized independent compensation consulting firm to assist it in carrying out
its responsibilities and its review and analysis of the executive compensation
program. Using that firm's proprietary database and identifying participants
with revenues between $10 billion and $20 billion as the Company's peer group,
the Committee establishes the parameters for meeting the base salary, short term
cash and long term compensation targets. This peer group includes a broad
cross-section of American companies. The Committee believes that these companies
provide the proper comparator group based on the size and complexity of the
Company's business. This report describes the policies and the criteria used by
the Committee in establishing the principal components of, and setting the level
of compensation for, executive officers.

THE COMPANY'S PHILOSOPHY OF EXECUTIVE COMPENSATION

The overall objective of the Company's executive compensation program is to
provide base salary and annual cash bonuses for executive officers at
approximately the median level for executive officers at companies similar in
size, complexity or line of business to McKesson HBOC, Inc. while providing long
term compensation at between the 50th and the 75th percentiles. The program is
designed to enhance shareholder value by linking a large part of executive
officers' compensation directly to the Company's performance.

Many factors enter into the Committee's deliberations on the appropriate levels
of short-and long-term compensation for individual executive officers of the
Company. The factors include the Company's performance as measured against
financial and nonfinancial targets approved by the Committee at the beginning of
each fiscal year; the individual performance of each executive officer; the
overall competitive environment for executives and the level of compensation
needed to attract and retain executive talent. The recommendations of, the
independent compensation consulting firm as well as surveys supplied by other
independent professional compensation consultants provide the quantitative basis
for the Committee's decisions.

COMPONENTS OF COMPENSATION

The Company's executive compensation program consists of base salary, a
short-term incentive plan and long-term incentives (stock options, restricted
stock and cash).

  Base Pay

Base salary is reviewed annually. Actual base salary is driven by individual
performance, competitive practices and level of responsibility. Salary increases
for FY 2001 reflect the Committee's determination that base salary levels should
be increased to recognize increased responsibilities and to remain competitive
at the median levels of targeted companies.

  Short Term Incentives

Under the Company's short-term incentive plan (the "Management Incentive Plan"
or "MIP"), individual target awards are set as a percentage of the executive's
base salary and vary by level of responsibility. The target awards are designed
to be competitive with those set for executive officers at companies in the
Company's executive compensation comparator group. Annual MIP awards can range
from zero to three times the executives' target awards and are determined by the
Company's and/or individual business unit's performance versus pre-established
objectives. The actual awards may be reduced from the maximums established by
the above procedure by the Committee exercising "negative discretion" in
accordance with regulations under Section 162(m) with respect to this type of
plan.

  Long Term Incentives

The Company's long-term incentive program has two components: a stock option
component and a cash component. Under this program:

- participants are granted nonqualified stock options to purchase shares of the
  Company's common stock at fair market value;

- the Committee establishes a target cash award for each participant under the
  Long-Term Incentive Plan ("LTIP"), the cash component of the long term
  incentive program, which cash award may have a service based component but
  otherwise is reduced if financial targets are not met.

                                        11
   15

Restricted stock, another form of long-term incentive, has been used by the
Company with the approval of the Committee on an individual basis for the
purpose of attracting and/or retaining key employees.

Under the Company's LTIP, target amounts for key senior executives, including
named executives, were established during FY 2001, which target amounts are
reflected in the table "Long-Term Incentive Plan Awards in the Last Fiscal
Year." These target amounts were established to ensure the retention of key
executives and were designed to enhance their focus on two key drivers of
shareholder value -- Earnings Before Interest and Taxes ("EBIT") and Return on
Committed Capital ("ROCC"). These target amounts were granted subject to a three
year performance cycle and payments, if any, will occur after the close of FY
2003.

POLICY REGARDING TAX DEDUCTION FOR COMPENSATION UNDER INTERNAL REVENUE CODE
SECTION 162(M)

Section 162(m) of the Code limits the Company's tax deduction to $1 million for
compensation paid to certain executive officers named in the proxy statement
unless the compensation is "performance based" within the meaning of Section
162(m). The MIP, previously approved by shareholders, meets the requirement of a
performance based pay program within the meaning of Section 162(m). Proceeds
from stock options granted under the 1994 Stock Option and Restricted Stock
Plan, which was also approved by shareholders, are also "performance based" and
are eligible for an exception to the deduction limitation. In the recent past,
the Company faced unique challenges in retaining key employees and the Committee
concluded that, in certain circumstances, it was appropriate to make grants of
options beyond the limits imposed and outside the structure of the 1994 Plan.
These grants are reflected in the table entitled Aggregate Options/SAR Exercises
in the Last Fiscal Year and Fiscal Year-End Options/SAR Values.

The Committee's intention is and has been to comply with the requirements of
Section 162(m) unless the Committee concludes that the required changes would
not be in the best interest of the Corporation or its stockholders.

COMPENSATION OF THE CHIEF EXECUTIVE OFFICER

In July 1999, John Hammergren and David Mahoney were named Co-Presidents and
Co-Chief Executive Officers. The Board agreed on the specific goals each would
work to achieve for FY 2001. For Mr. Hammergren, specific economic measures were
set including EBIT, ROCC and Earnings Per Share. Other goals included strategy
fulfillment, process improvement and staff development. Mr. Mahoney's objectives
focused on developing and launching the Company's internet strategy with a goal
of bringing new physician and medical management solutions to market within
specified financial parameters.

In February 2001, the internet strategy was reexamined and the assets previously
managed by Mr. Mahoney were integrated into other business units of the Company.
As a result of the reorganization, Mr. Mahoney's position as Co-President and
Co-Chief Executive Officer was eliminated as of March 31, 2001 and he has left
the Company. John Hammergren was named President and Chief Executive Officer
effective April 1, 2001.

During FY 2001, under Mr. Hammergren's leadership, McKessonHBOC achieved strong
financial performance across all lines of business. The Pharmaceutical Supply
Business produced strong results driven by substantial margin expansion. The
Information Technology Business stabilized its customer and employee bases and
refined its product mix.

In October 2000 and again in January 2001, Mr. Hammergren was awarded an option
to purchase 225,000 shares of McKesson HBOC Inc. common stock which awards are
reflected in the table "Option/SAR Grants in the Last Fiscal Year." These grants
are consistent with the Committee's guidelines for long-term compensation and
belief that executive compensation should be linked to increasing shareholder
value.

                                        12
   16

It is the Committee's view that the total compensation package for the Chief
Executive Officer for FY 2001, as reflected in the Summary Compensation Table
that follows, was based on an appropriate balance of the Corporation's
performance, his own performance and competitive practice.

(1) No options were granted with SARs and no freestanding SARs have ever been
    granted. Optionees may satisfy the exercise price by submitting currently
    owned shares and/or cash. Income tax withholding obligations may be
    satisfied by electing to have the Company withhold shares otherwise issuable
    under the option with a fair market value equal to such obligations.

(2) The option exercise price of the indicated options was 100% of the fair
    market value on the date of grant. The options become exercisable in
    installments of 25% on each of the first, second, third and fourth
    anniversaries of the date of grant and expire ten years after the date of
    the grant.

(3) In accordance with SEC rules, a modified Black-Scholes option-pricing model
    was chosen to estimate the grant date present value for the options set
    forth in this table. The assumptions used in calculating the reported value
    included: an option term of 5 years and a dividend yield of 0.75%; stock
    volatility, 48.5% and risk-free interest rate, 4.7%. The Company does not
    believe that the Black-Scholes model, or any other model, can accurately
    determine the value of an option. Accordingly, there is no assurance that
    the value, if any, realized by an executive, will be at or near this value
    estimated by the Black-Scholes model. Future compensation resulting from
    option grants is based solely on the performance of the Company's stock
    price.

ITEM 2. PROPOSAL TO AMEND THE 1997 NON-EMPLOYEE DIRECTORS' EQUITY COMPENSATION
AND DEFERRAL PLAN

We are asking stockholders to approve an amendment to the 1997 Non-Employee
Directors' Equity Compensation and Deferral Plan (the "Directors' Plan") to
increase the number of authorized shares of the Company's common stock under the
Directors' Plan by 750,000 shares.

The purpose of the Directors' Plan is to further align the interests of the
Company's directors with those of the Company's stockholders by requiring the
non-employee directors to elect to receive a portion of their compensation for
their services as directors in the form of Company securities. Directors who are
employees of the Company do not receive any compensation for service on the
Board. The Directors' Plan was first adopted by the Board and approved by the
stockholders in 1997 and replaced the Company's Retirement Program for
Non-Employee Directors. At the time of its adoption, 250,000 shares were
reserved for issuance under the Directors' Plan (which amount was subsequently
adjusted for a two-for-one stock split in January 1998). There are currently
460,000 shares issued and outstanding under the plan. The Directors' Plan was
further amended in January of this year, and if approved by the stockholders
761,000 shares will be available for grants. If the additional shares are not
approved, the Board will consider reinstating the former Retirement Program or a
similar program and the annual retainer and meeting fees will be paid in cash.

Non-employee directors receive an annual retainer of $27,500 and $1,000 for each
Board or Board committee meeting attended. Committee Chairmen receive an annual
retainer of $3,000. There are currently 10 non-employee directors.

TERMS OF THE PLAN

The Company's non-employee directors are required to defer 50% of their annual
retainer in the form of either Restricted Stock Units ("RSUs") or Nonqualified
Stock Options ("Options"). They may defer the remaining 50% of their annual
retainer in the form of RSUs or Options or to the Company's Deferred
Compensation Plan ("DCAP II"), or directors may elect to receive cash. Meeting
fees may also be deferred in the form of RSUs, DCAP II or the director may elect
to receive cash.

In January of each year, each director is also granted an Option for 10,000
shares of the Company's common stock. The Option vests on the date of grant and
has a term of 10 years.

The number of RSUs granted to each director electing to receive them is
determined by the amount of retainer and fees deferred divided by the fair
market value of the Company's common stock on the last trading day of the
calendar quarter in which those amounts would otherwise be payable. The number
of Options granted to each director so electing is determined by applying the
same conversion table used to determine the number of options granted to
employees in lieu of awards under the Company's Management Incentive Plan. For
2001, the conversion table was 20% of the closing price of the Company's shares
on January 31, 2001 which was divided into the amount to be deferred to
determine the number of options granted as the fair market value on the date of
grant.

Directors may also elect to defer the gain and subsequent taxation of an
exercise of an expiring Option. The shares resulting from an exercise are
credited to the director's account in the form of share units and are
distributed at a future time according to the director's election.

ITEM 3. PROPOSAL TO AMEND THE COMPANY'S RESTATED CERTIFICATE OF INCORPORATION TO
        CHANGE THE COMPANY'S NAME TO MCKESSON CORPORATION

The Company seeks to change its corporate name to McKesson Corporation. In
January 1999 as part of the acquisition of HBO & Company, the Company changed
its name from McKesson Corporation to McKesson HBOC, Inc.

The Board of Directors has adopted a resolution declaring it advisable to amend
the Company's Restated Certificate of Incorporation to change the name of the
Company as set forth above. The Board further directed that the name change be
submitted for consideration by the stockholders at the Meeting.

As amended, Article I of the Company's Restated Certificate of Incorporation
would read in its entirety as follows: The name of the Corporation is "McKesson
Corporation."

The Board of Directors believes changing the name of the Company to McKesson
Corporation is in the Company's best interest at this time because the proposed
new corporate name is more streamlined and simple than the current corporate
name, and also embodies both the heritage and mission of the Company. The new
name reflects the Company's unified strategy for improving the performance of
healthcare by delivering solutions that integrate products and services from
across its business to meet the needs of a broad range of healthcare customers.

If approved, the McKesson name not only would be adopted by the Company, but
also incorporated into the names of all of the Company's subsidiaries and
divisions. A new logo and graphic system that manifests the mission and aligns
the corporate nomenclature and graphics to reinforce the Company's integrated
organization and strategy is being developed. Should the name change be
approved, transition to the new name and graphic identity system will be
implemented on a staged basis, to smooth the impact of the related expense.

In the event the proposed name change is approved by the stockholders, the
Company will thereafter file a Certificate of Amendment to its Restated
Certificate of Incorporation with the Delaware Secretary of State amending
Article 1 which will become effective at the close of business on the date the
Secretary of State accepts that filing.

EMPLOYMENT AGREEMENTS, EXECUTIVE SEVERANCE POLICY AND TERMINATION OF EMPLOYMENT
AND CHANGE IN CONTROL ARRANGEMENTS

  Employment Agreements

The Company has entered into an employment agreement ("Agreement") with each of
Messrs. Seelenfreund, Hammergren, Mahoney, King and Julian that provides for,
among other things, the term of employment, compensation and benefits payable
during the term of the Agreement as well as for specified payments in case of
termination of employment. In each case,

                                        18
   22

the Agreement provides that the executive will participate in all compensation
and fringe benefit programs made available to all executive officers.

The Company entered into an Agreement with Alan Seelenfreund, dated as of August
1, 1999, which by its terms provides for expiration on June 30, 2001. The
Agreement provides for an annual base salary of at least $500,000 and additional
incentive compensation, if any, as may be determined by the Board of Directors;
provided that, any incentive compensation awarded under the MIP will be
calculated using an individual target award of 100% of base salary. The
Agreement also provides Mr. Seelenfreund with options to purchase 1 million
shares of the Company's common stock with an exercise price of $29.8125 per
share. In addition, the Agreement provides that, in the event (i) the Company
terminates Mr. Seelenfreund's employment without "Cause" or (ii) he terminates
his employment for "Good Reason" (each as defined in the Agreement), he will be
entitled to (A) his then base salary and incentive compensation (using an
individual target award of 100% of base salary), for the remainder of the term
of the Agreement; (B) continued monthly automobile allowance for the remainder
of the term of the Agreement; and (C) accelerated vesting of all his stock
options. Under such circumstances, Mr. Seelenfreund's participation in the
Company's tax-qualified profit-sharing plans and stock purchase plans will
terminate as of his date of termination, in accordance with the plans. Under the
Agreement, the Company will pay Mr. Seelenfreund a gross-up payment to cover the
excise taxes and interest imposed on "excess parachute payments" as defined in
Section 280G of the Code.

The Company entered into amended and restated Agreements with each of John H.
Hammergren and David L. Mahoney, respectively, effective as of June 21, 1999,
replacing their prior employment agreements with the Company. The term of the
Amended and Restated Agreements shall expire March 31, 2004, and in the case of
Mr. Hammergren, provides that the term will be automatically extended by one
year on March 31, 2004, and each anniversary thereof, unless either party gives
notice that such term will not be so extended. As a result of the restructuring
and reorganizing of the iMcKesson business unit, Mr. Mahoney's position as
Co-President and Co-Chief Executive Officer of the Company was eliminated
effective March 31, 2001. Mr. Mahoney is no longer with the Company; however,
pursuant to the terms of his Agreement he will be entitled to receive the
compensation and benefits specified in clauses (A) through (F) below. Each
Agreement provides for an annual base salary of at least $750,000 and such
additional incentive compensation, if any, as may be determined by the Board of
Directors; provided that, any incentive compensation awarded to either executive
under the Company's MIP shall be calculated using an Individual Target Award of
100% of base salary. In addition, each executive was granted options to purchase
2 million shares of Company common stock at an exercise price of $29.8125 per
share. In addition, each Amended and Restated Agreement provides that, in the
event (i) the Company terminates the executive without "Cause," (ii) the
executive terminates for "Good Reason" (each as defined in the Agreements) or
(iii) the Company elects not to extend the term of the Agreement, the executive
will be entitled to (A) receive payment of his then base salary and incentive
compensation (using an Individual Target Award of 100% of base salary), for the
remainder of the term of the Agreement, but in no event for less than two years;
(B) continued monthly automobile allowance and participation in the Deferred
Compensation Administration Plan II for the term of the Agreement, (C) continued
accrual and vesting in his rights and benefits under the Executive ESBP and
EBRP, calculated on the basis of his receiving (x) Approved Retirement
commencing on the expiration of the Agreement and (y) with respect to the EBRP,
a benefit calculated on the basis of 60% of Average Final Compensation then
specified in the EBRP without any reduction for early retirement (see "Pension
Benefits"), (D) lifetime coverage under the Company's Executive Medical Plan and
financial counseling program, as well as, lifetime office space and secretarial
support; (E) accelerated vesting of all his stock options and restricted stock;
(F) with respect to Long Term Incentive Plan awards receive such awards on a
pro-rata basis in accordance with the terms and conditions applicable to
Approved Retirement with the exception that the "Service-based Portion of the
Target Award," if any, shall be paid as if executive continued employment
throughout the performance period. In the event such termination occurs within
two years following a Change
                                        19
   23

in Control (as defined in the Amended and Restated Agreement), executive will be
entitled to a gross-up payment to cover the excise taxes and interest imposed on
"excess parachute payments" as defined in Section 280G of the Code.

The Company entered into an Agreement with Graham O. King effective as of June
21, 1999. The term of the Agreement shall expire the earlier of March 31, 2004
or the date that Mr. King shall have been granted "Approved Retirement" status
under the Company's EBRP. The Agreement provides for an annual base salary of at
least $580,000, a retention payment of $2.5 million, payable in two installments
of $1.25 million, plus such additional incentive compensation, if any, as may be
determined by the Board; provided that any compensation awarded to Mr. King
under the Company's MIP shall be calculated using an Individual Target Award of
75% of base salary. Mr. King was granted a nonqualified option to purchase 1
million shares of the Company's common stock, with an exercise price of $29.8125
per share. With respect to Mr. King's participation in the EBRP and ESBP, the
Chief Executive Officer shall recommend to the Board that he be granted Approved
Retirement upon the satisfaction of certain requirements, and if Mr. King
accrues 5 years of actual service credit pursuant to the EBRP and the ESBP, he
shall be granted additional service credit for prior service with HBOC and a
previous employer. The Agreement provides that in the event the Company
terminates the executive without "Cause" or the executive terminates for "Good
Reason," both as defined in the Agreement, the Company shall (A) continue his
then base salary, reduced by any compensation he receives from a subsequent
employer during such term (B) consider him for a bonus under the Company's MIP
for the fiscal year in which termination occurs (C) continue his automobile
allowance, financial planning allowance and Executive Medical Plan benefits
until the expiration of the Agreement, (D) continue the accrual and vesting of
his rights, benefits and existing awards for purposes of the EBRP, ESBP, and
Stock Option and Restricted Stock Plan.

The Company entered into an Agreement with Paul C. Julian, effective as of
August 1, 1999 which Agreement was amended in 2000. The term of the Agreement
shall expire March 31, 2004. The Agreement provides for an annual base salary of
at least $500,000 and such additional compensation, if any, as may be determined
by the Board of Directors; provided that, any incentive compensation awarded to
the executive under the Company's MIP shall be calculated using an Individual
Target Award of 75% of base salary, reduced by any compensation he receives from
a subsequent employer during such term. In addition, Mr. Julian was granted
options to purchase 200,000 shares of Company common stock with an exercise
price of $29.8125 per share. The Agreement provides that, in the event the
Company terminates the executive without "Cause," or the executive terminates
for "Good Reason," both as defined in the Agreement, the Company shall (A)
continue his then base salary, reduced by any compensation he receives from a
subsequent employer during such term (B) consider him for a bonus under the
Company's MIP for the fiscal year in which termination occurs, (C) continue his
automobile allowance and Executive Medical Plan benefits until the expiration
date of the Agreement (D) continue the accrual and vesting of his rights,
benefits and existing awards for the remainder of the term of the Agreement for
purposes of the EBRP, ESBP and the Stock Option and Restricted Stock Plan.

The Company may terminate any of the executives, under the terms of their
respective Agreements, for "cause" (as defined in each Agreement) in which case
the Company's obligations under the Agreements cease.

In the event any executive is prevented from performing his duties under his
respective Agreement due to a disability, the Company shall continue to pay the
current salary during the period of disability, provided however that if the
executive is continuously disabled for more than 12 months, the Company's
obligations under the Agreement cease. In the event of death of the executive
during the term of the Agreement, his salary will continue to be paid to his
surviving spouse for six months following the death and thereafter the Company's
obligations under the Agreement cease.

                                        20

  Executive Severance Policy

The Company has implemented an Executive Severance Policy (the "Policy"), which
applies in the event an executive officer is terminated by the Company for
reasons other than for cause at any time other than within two years following a
change in control (as defined in the Policy) of the Company. The benefit payable
to executive officers under the Policy is equal to 12 months' base salary plus
one month's pay per year of service, up to a maximum of 24 months. Such benefits
would be reduced or eliminated by any income the executive officer receives from
subsequent employers during the severance payment period. Executive officers who
are age 55 or older and have 15 or more years of service with the Company at the
time of such involuntary termination are granted "approved retirement" for
purposes of the EBRP and the ESBP. The Policy also provides that, upon such
involuntary termination, awards under the LTIP are prorated for all cycles then
in progress. In addition, vesting of stock options and lapse of restrictions on
restricted stock awards will cease as of the date of termination, and no
severance benefits will be paid beyond age 62. A terminated executive who is
receiving payments under the terms of an employment agreement he or she may have
with the Company is not entitled to receive additional payments under the
Policy.

  Termination of Employment and Change in Control Arrangements

The Company has entered into termination agreements with all of its executive
officers, including the Named Executive Officers. The agreements operate
independently of the Policy, continue through December 31 of each year, and are
automatically extended in one-year increments until terminated by the
Compensation Committee (or by the Board of Directors in the case of the Chief
Executive Officer). The agreements are automatically extended for a period of
two years following any change in control.

The agreements provide for the payment of certain severance and other benefits
to executive officers whose employment is terminated within two years of a
change in control of the Company. Specifically, if following a change in
control, the executive officer is terminated by the Company for any reason,
other than for "Cause" (as defined in the agreements), or if such executive
officer terminates his or her employment for "Good Reason" (as that term is
defined in the agreements), then the Company will pay to the executive officer,
as severance pay in cash, an amount equal to 2.99 times his or her "base amount"
(as that term is defined in Section 280G of the Code) less any amount which
constitutes a "parachute payment" (as defined in Section 280G). The Company will
also continue the executive officer's coverage in the health and welfare benefit
plans in which he or she was a participant as of the date of termination of
employment, and the executive officer will continue to accrue benefits under the
EBRP, in both such cases for the period of time with respect to which the
executive officer would be entitled to payments under the Policy described above
if the executive officer's termination of employment had been covered by such
Policy. In addition, if the executive officer is age 55 or older and has 15 or
more years of service (as determined under such plan on the date of executive's
termination of employment), then such termination will automatically be deemed
to be an "approved retirement" under the terms of the EBRP. The amount of
severance benefits paid shall be no higher than the amount that is not subject
to disallowance of deduction under Section 280G of the Internal Revenue Code.

  Change in Control

For purposes of the termination agreements and as used elsewhere in this proxy
statement, a "change in control" is generally deemed to occur if: (i) any
"person" (as defined in the Securities Exchange Act of 1934, as amended) other
than the Company or any of its subsidiaries or a trustee or any fiduciary
holding securities under an employee benefit plan of the Company or any of its
subsidiaries, acquires securities representing 30% or more of the combined
voting power of the Company's then outstanding securities; (ii) during any
period of not more than two consecutive years, individuals who at the beginning
of such period constitute the Board of Directors of the Company and any new
director whose election by the Board of Directors or nomination for election
                                        21
   25

by the Company's stockholders was approved by a vote of at least two-thirds
( 2/3) of the directors then still in office who either were directors at the
beginning of the period or whose election or nomination for election was
previously so approved, cease for any reason to constitute a majority thereof;
(iii) the stockholders of the Company approve a merger or consolidation of the
Company with any other Company, other than (a) a merger or consolidation which
would result in the voting securities of the Company outstanding immediately
prior thereto continuing to represent, in combination with the ownership of any
trustee or other fiduciary holding securities under an employee benefit plan of
the Company, at least 50% of the combined voting power of the voting securities
of the Company or such surviving entity outstanding immediately after such
merger or consolidation, or (b) a merger or consolidation effected to implement
a recapitalization of the Company (or similar transaction) in which no person
acquires more than 50% of the combined voting power of the Company's then
outstanding securities; or (iv) the stockholders approve a plan of complete
liquidation of the Company or an agreement for the sale or disposition by the
Company of all or substantially all of its assets.

PENSION BENEFITS

The table below illustrates the estimated combined annual benefits payable upon
retirement at age 62 under the Company's qualified retirement plan and
supplemental EBRP in the specified compensation and years of service
classifications. The benefits are computed as single life annuity amounts.

The benefit under the EBRP is a percentage of final average pay based on years
of service or as determined by the Board of Directors. The maximum benefit is
60% of final average pay. The total paid under the EBRP is not reduced by Social
Security benefits but is reduced by those benefits payable on a single life
basis under the Company's qualified retirement plan and the annuitized value of
the Retirement Share Plan allocations of common stock made to the PSIP assuming
12% growth in the value of the stock. Messrs. Hammergren and Mahoney will
receive benefits from the EBRP based on 60% of final pay and not reduced by any
early retirement reduction (see "Employment Agreements").

The compensation covered under the plans whose benefits are summarized in the
above table includes the base salary and annual bonus amounts reported in the
Summary Compensation Table plus any annual bonus amounts foregone to purchase
grants of Bonus Options.

The estimated years of service for purposes of the EBRP at March 31, 2001 for
certain of the Named Executive Officers are as follows: Mr. Hammergren, 5; Mr.
Mahoney, 9; Mr. King, 2; Mr. Julian, 3 and Mr. Graber, 1.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

The Company and its subsidiaries have transactions in the ordinary course of
business with unaffiliated companies of which certain of the Company's
non-employee directors are directors and/or executive officers. The Company does
not consider the amounts involved in such transactions to be material in
relation to the businesses of such other companies or the interests of the
directors involved. The Company anticipates that similar transactions will occur
in fiscal year 2002.

CERTAIN LEGAL PROCEEDINGS

Since the Company's announcements in April, May and July of 1999 that certain
software sales transactions in its Information Technology Business Unit,
formerly HBOC, were improperly recorded as revenue and reversed and, as of April
30, 2001, eighty-five lawsuits have been filed against the Company, certain of
its current or former directors or officers, and other defendants. Sixty-four of
these actions have been filed in Federal Court (the "Federal Actions"); of
these, fifty-nine were filed in the U.S. District Court for the Northern
District of California.

On November 2, 1999, the Honorable Ronald M. Whyte of the Northern District of
California issued an order consolidating fifty-three of the Federal Actions into
one action entitled In re McKesson HBOC, Inc. Securities Litigation, (Case No.
C-99-20743-RMW) (the "Consolidated Action"). On December 22, 1999, Judge Whyte
appointed the New York State Common Retirement Fund as lead plaintiff ("Lead
Plaintiff") and approved Lead Plaintiff's choice of counsel.

On February 25, 2000, Lead Plaintiff filed an Amended and Consolidated Class
Action Complaint (the "ACCAC"). The ACCAC (as well as the other pending federal
and state actions) generally allege that the defendants violated the federal
securities laws in connection with the events leading to the Company's decision
to restate its financial statements. On September 28, 2000, Judge Whyte
dismissed all of the ACCAC claims against the Company under Section 11 of the
Securities Act of 1933 ("Securities Act") with prejudice, dismissed a claim
under Section 14(a) of the Securities Exchange Act of 1934 ("Exchange Act") with
leave to amend and declined to dismiss a claim against the Company under Section
10(b) of the Exchange Act.

On November 14, 2000, Lead Plaintiff filed its Second Amended and Consolidated
Class Action Complaint ("SAC"). As with its ACCAC, Lead Plaintiff's SAC
generally alleges that the defendants named therein violated the federal
securities laws in connection with the events leading to the Company's
announcements in April, May and July, 1999. The SAC names the Company, HBOC,
certain current or former officers or directors of the Company or HBOC, Arthur
Andersen and Bear Stearns as defendants. The SAC purports to state claims
against the Company under Section 10(b) and 14(a) of the Exchange Act. Directors
and former directors Bitterman, Friedman, Pietruski, Pottruck, Reichardt,
Seelenfreund, Shaw and Waterman are named as defendants in the SAC under Section
14(a) of the Exchange Act. On January 18, 2001, the Company and all Directors
and former directors and officers named as defendants, moved to dismiss claims
under Section 14(a) of the Exchange Act in its entirety, and the Company moved
to dismiss the claim under Section 10(b) to the extent it is based on statements
and conduct of the Company prior to the merger. HBOC also filed its own motion
to dismiss the claim based on Section 14(a) of the Exchange Act insofar as that
claim is asserted on behalf of McKesson shareholders. These motions were heard
on March 23, 2001, and the Court has not yet issued a ruling.

Twenty-one actions have also been filed in various state courts in California,
Colorado, Delaware, Georgia, Louisiana and Pennsylvania (the "State Actions").
The State Actions are generally based on the same transactions and events giving
rise to the Consolidated Action. Two of the State Actions are shareholder
derivative actions purportedly brought on behalf of the Company: Ash, et al. v.
McCall, et al. (Del C.A. No. 17132), filed in the Delaware Chancery Court, and
Mitchell v. McCall et al. (Case No. 304415), filed in California Superior Court,
City and County of San Francisco. The Company is a nominal defendant in these
actions and the plaintiffs seek to assert claims against the Directors (other
than Mr. Koffel and Mr. Hammergren), certain former directors and others on
                                        23
   27

behalf of the Company. Directors were named as defendants in only two additional
State Actions: Carroll v. McKesson HBOC, Inc., (Case No. 17454), and Kelly v.
McKesson HBOC, Inc., et al. (Case No. 17282-NC). Both of these actions were
filed in the Delaware Superior Court and were voluntarily dismissed without
prejudice. Included as defendants in the remaining seventeen State Actions are
the Company, HBOC and certain former officers or directors. None of the State
Actions name Mr. Koffel or Mr. Hammergren as a defendant.

INDEBTEDNESS OF EXECUTIVE OFFICERS

Under the 1999 Executive Stock Purchase Plan (the "1999 ESPP"), full recourse
unsecured loans for the purchase of Company common stock, having a term of five
years and bearing interest at the rate of 4.7% per annum, were made on February
5, 1999 (the "Purchase Date") to certain executive officers, including Messrs.
Hammergren and Mahoney. Pursuant to the 1999 ESPP, Messrs. Hammergren and
Mahoney purchased 100,000 shares each, all at a purchase price of $63.8125 per
share, which was the fair market value of the common stock on the Purchase Date.
In addition, under the Stock Purchase Plan (the "SPP") full recourse loans,
having a term of five years, bearing interest at the rate of 4.7% per annum,
were made on the Purchase Date to certain executive officers and other key
executives not named in the Summary Compensation Table. Such loans were for the
purchase of common stock at the fair market value on the Purchase Date and are
secured by a pledge of the shares purchased under the SPP. In fiscal years 1998,
1997, and 1995 additional loans to certain executive officers named in the
Summary Compensation Table and other executive officers of the Company were made
under the SPP to purchase common stock at the fair market value on the dates of
purchase, bearing interest from 7.1% to 8% per annum. All shares purchased by
the current executive officers under the 1999 ESPP and the SPP are included in
the Security Ownership of Directors and Executive Officers table on page 5.

The table below shows, as to each executive officer who was indebted to the
Company in an amount exceeding $60,000 at any time during the period April 1,
2000 through May 1, 2001, (i) the largest aggregate amount of indebtedness
outstanding during such period, and (ii) the amount of indebtedness outstanding
at May 1, 2001. For each individual listed in the table below, unless additional
loans are described later in this paragraph, the indebtedness shown resulted
from loans previously outstanding or those made on the Purchase Date under the
1999 ESPP or under the SPP. The indebtedness shown for Messrs. Hammergren,
Graber and Kirincic also includes the balance owed on a secured housing loan in
the original principal amount of $500,000 each. The indebtedness shown for Mr.
Julian also includes the balance owed on secured housing loans in the aggregate
amount of $1,750,000. These housing loans are without interest unless and until
the individuals fail to pay any amount under the loans when due and thereafter
at a market rate. See footnote 2 to the Summary Compensation Table on page 13
for further information regarding the housing loans made to Messrs. Hammergren,
Julian and Graber.

AUDIT COMMITTEE REPORT

The Audit Committee of the Company's Board of Directors (the "Audit Committee")
assists the Board in fulfilling its responsibility for oversight of the quality
and integrity of the Company's financial reporting processes. The functions of
the Audit Committee are described in greater detail in the Audit Committee's
written charter, which has been adopted by the Company's Board of Directors. A
copy of the charter is attached to this Proxy Statement as Appendix A. The
Committee is composed exclusively of directors who are independent under the New
York Stock Exchange listing standards. Management has the primary responsibility
for the financial statements and the reporting process, including the system of
internal controls. The Company's independent auditors, Deloitte & Touche LLP,
are responsible for performing an independent audit of the Company's
consolidated financial statements in accordance with generally accepted auditing
standards and for issuing a report thereon.

The Audit Committee has reviewed and discussed the audited financial statements
of the Company for the year ended March 31, 2001 (the "Audited Financial
Statements") with management. In addition, the Audit Committee has discussed
with Deloitte & Touche LLP the matters required to be discussed by Statement on
Auditing Standards No. 61 (Communications with Audit Committees), as amended.

The Audit Committee also has received the written disclosures and the letter
from the independent auditors required by the Independence Standards Board
Standard No. 1 (Independence Discussions with Audit Committees) and has
discussed with that firm its independence from the Company. The Audit Committee
further considered whether the provision of the non-audit related services by
Deloitte & Touche LLP to the Company is compatible with maintaining the
independence of Deloitte & Touche LLP from the Company. The Audit Committee has
also discussed with management of the Company and Deloitte & Touche LLP such
other matters and received such assurances from them as it deemed appropriate.

In reliance on the reviews and discussions referred to above, the Audit
Committee recommended to the Board of Directors, and the Board has approved,
that the audited financial statements be included in the Company's Annual Report
on Form 10-K for the period ended March 31, 2001 for filing with the SEC. The
Committee has also recommended to the Board, subject to stockholder
ratification, the selection of Deloitte & Touche LLP as the Company's
independent auditors for 2002, and the Board concurred in its recommendation.

ITEM 4. RATIFICATION OF APPOINTMENT OF DELOITTE & TOUCHE LLP AS INDEPENDENT
AUDITORS FOR 2002

The Audit Committee of the Board has recommended, and the Board of Directors has
approved Deloitte & Touche LLP as the independent auditor to audit the
consolidated financial statements of the Company and its subsidiaries for the
fiscal year ending March 31, 2002. Deloitte & Touche LLP has acted as the
Company's independent auditors for several years, is knowledgeable about the
Company's operations and accounting practices, and is well qualified to act in
the capacity of independent auditors.

Representatives of Deloitte & Touche LLP are expected to be present at the
Meeting to respond to appropriate questions and to make a statement if they
desire to do so.

                                        25

The aggregate fees billed by Deloitte & Touche, LLP, the member firms of
Deloitte & Touche Tomatsu, and their respective affiliates for the fiscal year
ended March 31, 2001 are as follows:

ITEMS 5 THROUGH 7. STOCKHOLDER PROPOSALS

We expect the following proposals to be presented by stockholders at the annual
meeting. Following SEC rules, other than minor formatting changes, we are
reprinting the proposals and supporting statements as they were submitted to us.
We take no responsibility for them. FOR THE REASONS SET FORTH AFTER EACH OF
THESE PROPOSALS, THE BOARD RECOMMENDS A VOTE "AGAINST" ITEMS 5 THROUGH 7.

ITEM 5. STOCKHOLDER PROPOSAL REGARDING PERFORMANCE-BASED OPTIONS

The Company has received the following stockholder proposal from the Amalgamated
Bank of New York Longview Collective Investment Fund, 11-15 Union Square, New
York, N.Y. 10003, the beneficial owner of 93,120 shares of common stock:

     "Resolved: The shareholders of McKesson HBOC, Inc. ("McKesson") urge the
board of directors to adopt an executive compensation policy that all future
stock option grants to senior executives shall be performance-based.
"Performance-based" stock options are defined here as (1) indexed options, whose
exercise price is linked to an industry index, such as the Value Line Healthcare
Sector Index; (2) premium-priced stock options, whose exercise price is
significantly above the market price on the grant date; or (3)
performance-vesting options, which vest when the market price of the stock
exceed a specific target."

                              Supporting Statement

     McKesson's performance has been disappointing with the stock trading at
less than half its value two years ago. Although we appreciate the importance of
attracting talented managers, we believe that current compensation policies need
to focus more on improved performance.

     According to compensation expert Graef Crystal, former CEO Mark Pulido's
total pay in 1999 was $135 million, a figure computed by adding salary, bonus,
estimated present value at grant of stock options awarded that year, value at
grant of free shares of stock, payouts made under long-term incentive programs
("LTIPs") and "other annual" and "all annual compensation" as defined by the
SEC. Using a formula designed to correlate performance and executive pay and to
compare an individual CEO's compensation with that of peers in the industry
group, Mr. Crystal calculated that Mr. Pulido was overpaid by 979% compared to
his peers.

     Following Mr. Pulido's resignation, John Hammergren and David Mahoney were
appointed co-CEOs. According to McKesson's 2000 proxy materials, their base pay
was $750,000 each. The company's short-term incentive pay is based on
performance; as a result, these executives received no short-term incentive pay,
although they did receive some payment under a 'former' LTIP.

     The current pay packages are not as large as Mr. Pulido's, but a review of
the 2000 proxy materials suggests that the Compensation Committee may be more
interested in paying "at the 75th percentile" for long-term compensation than
with actual performance. We note that in August 1999, soon after their
appointment, Messrs. Hammergren and Mahoney were given an option to buy
2,000,000 shares each, with an estimated present value of $25,400,000 each. In
January 2000, they were granted an additional option to purchase 300,000 shares
at fair market value (present value

                                        26
   30

$2,700,000) and they received free grants of 200,000 shares each, valued at the
time at $4,200,000 each. In addition, Mr. Hammergren's employment agreement
provides him with several "initial incentive awards" that are unrelated to
performance.

     We are concerned by this practice. The fact that McKesson's poor
performance precludes compensation under existing performance-based plans has
not stopped McKesson from making new grants that may not be directly tied to
performance. In our view, this sets the wrong incentives for management and
underscores the need for a compensation policy that more explicitly and
effectively ties option grants to improved performance.

     We urge you to vote FOR this resolution.

YOUR BOARD'S RECOMMENDATION AGAINST THE PROPOSAL REGARDING PERFORMANCE-BASED
OPTIONS

The Board has considered this proposal and believes that its adoption is
unnecessary and would not be in the best interests of the Company or its
stockholders.

As set forth in the Compensation Committee report on page 10, the Board
recognizes the need to link compensation with performance; and it believes that
its current approach to executive compensation decisions focuses on
performance-based compensation. The Compensation Committee's decisions on
compensation for executive officers are based on an analysis of the executive's
overall performance for the year as well as competitive market practices at the
selected group of comparator companies referenced earlier. In reviewing
individual performances, the Compensation Committee considers such factors as
financial performance of the Company, the executive's contribution to achieving
the Company's goals and performance of the business units or functions over
which the individuals have responsibility. The financial performance factors
include return on capital, earnings before interest and taxes, earnings per
share, revenue growth, and total stockholder return. Performance goals are
annually reviewed and approved by the Board. In addition, the Compensation
Committee (the members of which are solely non-employee Directors) considers
advice provided by an independent executive compensation consultant on market
compensation and performance in making its recommendations.

The Compensation Committee and the Board believe that they have already
established a process that enables them to fairly determine and properly make
performance-based compensation decisions concerning the Company's executive
officers. The Board believes that it should retain the flexibility to make these
decisions based on a review of all relevant information including specific
financial and non-financial performance results without imposing rigid, pre-set
constraints. The constraints recommended in the proposal could put the Company
at a competitive disadvantage in terms of retaining and recruiting executive
talent, inasmuch as the option structure currently used by the Company reflects
the most widely used approach among corporations today.

The Company's Stock Option and Restricted Stock Plans are designed to provide
long-term incentives and align the interests of executive officers with those of
all stockholders. Stock options awarded under the Plans are designed to motivate
the executive to increase the value of the Company, which concurrently benefits
not only the executive but the Company's stockholders as a whole.

ITEM 6. STOCKHOLDER PROPOSAL REGARDING SEVERANCE PAYMENTS

The Company has received the following stockholder proposal from the
International Brotherhood of Teamsters, 25 Louisiana Avenue, N.W., Washington,
D.C. 20001, which owns 80 shares of common stock:

RESOLVED: Shareholders urge that the Board of Directors adopt a policy that
executive officer severance pay of over $3 million must be approved by the
shareholders as a separate issue for vote at the annual shareholder meeting, and
no future employment contracts will be entered into which

                                        27
   31

include severance clauses of more than $3 million, without shareholder's
approval. Such a policy would be phased in and will not affect current
contractual agreements.

SUPPORTING STATEMENT: In 2000, McKesson HBOC paid ousted CEO Mark Pulido $1.9
million and guaranteed him that salary through the year 2004. Pulido even
received an $853,000 bonus in 2000. Pulido received this severance package,
after he presided as CEO over Mckesson's stock debacle concerning incorrect
financial reporting during the merger with HBO Company. In 1999, he was paid
$90.3 million including stock options. Such excessive compensation and severance
pay is a perversion of the sound corporate practice of paying for performance.

Recent outcry against excessive executive compensation has included criticism of
companies, which have awarded overly generous severance packages. When Disney
awarded Michael Ovitz $70 million in cash and options as severance for 16 months
of service, for example, shareholders expressed outrage.

Union Pacific granted a special $4 million bonus to Drew Lewis upon his
retirement; Electronic Data Systems negotiated a $35 million termination
agreement with Lester Alberthal; and, this year Proctor & Gamble granted $9.5
million to retiring Chairman Dick Jager.

Shareholders should be the ultimate judges of executive performance. The
evaluation of what an executive is worth when not in the employ of the company
should be the decision of shareholders.

We urge shareholders to vote FOR this proposal.

YOUR BOARD'S RECOMMENDATION AGAINST THE PROPOSAL REGARDING SEVERANCE PAYMENTS

The Board has considered this proposal and believes that its adoption would not
be in the best interests of the Company or its stockholders.

In order to attract, retain and reward executives in a competitive business
environment, it is critical that the Company maintain the flexibility to design
employment arrangements which address the specific facts and circumstances of
each executive's situation. Because of the market competition for qualified
executives, the Company must have the ability to offer competitive employment
packages to retain its own executives, as well as to motivate other valuable
executives to relocate to the Company. Further, when negotiating potential
business combinations, the Company must provide competitive incentives to ensure
that the key executive team remains with the Company. Adoption of this proposal
would place the Company at a competitive disadvantage because it would
arbitrarily limit the Company's flexibility to design employment arrangements
that can attract and retain qualified executives.

The Compensation Committee determines whether the Company should enter into
employment agreements with the Company's top executive officers. All employment
arrangements with the Chief Executive Officer must be first recommended by the
Compensation Committee and are then subject to further review and approval by
the Board. In the event that the Compensation Committee believes that an
employment agreement is in the best interests of the Company and its
stockholders, it needs the flexibility to offer the agreement without delay.
This flexibility would be substantially undermined by a requirement for
stockholder approval.

The Corporation cannot afford to impose a condition of shareholder approval on
agreements with those key executives necessary for the operation of the
Corporation's business. The type of executives that the Company seeks are
frequently being pursued by other entities as well, and the Company could lose
these individuals to competitors which are not burdened by the stockholder
approval condition. Adoption of the proposal would require the Company to incur
significant time and expense to either convene a special stockholders' meeting
for the sole purpose of voting on this type of agreement, or delay finalizing
such agreement until after its approval at the annual stockholders' meeting. In
either case, the Company would be at a competitive disadvantage in

                                        28
   32

attracting qualified executives who do not want to be subject to the delay and
uncertainty created by the stockholder approval provision.

ITEM 7. STOCKHOLDER PROPOSAL REGARDING THE SALE OF THE COMPANY

The Company has received the following stockholder proposal from William
Steiner, 4 Radcliffe Drive, Great Neck, New York, 11024, who owns 1,300 shares
of common stock:

                           MAXIMIZE VALUE RESOLUTION

     Resolved that the shareholders of McKesson HBOC, Inc. urge the McKesson
HBOC, Inc. Board of Directors to arrange for the prompt sale of McKesson HBOC,
Inc. to the highest bidder.

     The purpose of the Maximize Value Resolution is to give all McKesson HBOC,
Inc. shareholders the opportunity to send a message to the McKesson HBOC, Inc.
Board that they support the prompt sale of McKesson HBOC, Inc. to the highest
bidder. A strong and or majority vote by the shareholders would indicate to the
board the displeasure felt by the shareholders of the shareholder returns over
many years and the drastic action that should be taken. Even if it is approved
by the majority of the McKesson HBOC, Inc. shares represented and entitled to
vote at the annual meeting, the Maximize Value Resolution will not be binding on
the McKesson HBOC, Inc. Board. The proponent however believes that if this
resolution receives substantial support from the shareholders, the board may
choose to carry out the request set forth in the resolution.

     The prompt auction of McKesson HBOC, Inc. should be accomplished by any
appropriate process the board chooses to adopt including a sale to the highest
bidder whether in cash, stock, or a combination of both. It is expected that the
board will uphold its fiduciary duties to the utmost during the process.

     The proponent further believes that if the resolution is adopted, the
management and the board will interpret such adoption as a message from the
company's stockholders that it is no longer acceptable for the board to continue
with its current management plan and strategies.

                 I URGE YOUR SUPPORT, VOTE FOR THIS RESOLUTION

YOUR BOARD'S RECOMMENDATION AGAINST THE PROPOSAL REGARDING THE SALE OF THE
COMPANY

The Board of Directors of the Company has considered this proposal and believes
that its adoption is unnecessary and would not be in the best interests of the
Company or its shareowners.

The proposed resolution calls for the prompt sale of the Company to the highest
bidder without regard to the adequacy of the consideration, or the relative
benefits to shareowners of other alternatives. The implementation of the
proposed resolution would be totally inconsistent with the Board's duty to
maximize shareowner value and protect the interests of all of the Company
shareowners.

Consistent with its fiduciary duty, the Board of Directors seeks to manage the
Company's affairs in a manner it believes to be in the best interests of the
Company and its shareowners. To this end, the Board will carefully consider any
bona fide proposal which it believes has the potential to increase shareowner
value, including a bona fide proposal for the acquisition of the Company.
However, the fiduciary duty of the Board will not permit it to facilitate a bid
that does not reflect the intrinsic value of the Company.

The initiation of an "auction" in the manner contemplated by the proposed
resolution would, in the opinion of the Board, be completely inconsistent with
the shareowners' interests. In the Board's opinion, the initiation of such an
auction could create a "forced sale" atmosphere which could actually have the
effect of reducing the perceived value of the Company to a "fire sale" level,
thus forcing the Company to negotiate with bidders from a position of weakness.
Moreover, the
                                        29
   33

uncertainty created by a publicly announced auction could adversely affect the
Company's relationships with its lenders, customers, suppliers, employees and
other constituencies, thus potentially lowering rather than raising the value of
the Company.

The Company's Board of Directors regularly analyzes strategic alternatives
consistent with their fiduciary duties. Such analyses require a review of a
broad range of information regarding the Company's business, prospects,
industry, competition and products, as well as countless other factors that a
Board must consider in performing its oversight responsibilities. Decisions to
sell a company do not, as the proponent suggests, arise in a vacuum. Rather,
such a decision is typically only one potential outcome a Board may reach after
it thoroughly analyzes all of its strategic alternatives and concludes that a
sale of the Company is the optimal decision.

Management welcomes input from the Company's stockholders and will carefully
consider meaningful suggestions it receives to increase or maximize stockholders
value. However, for the reasons set forth above, the Board of Directors
unanimously urges a vote against the foregoing proposal.

SECTION 16(A) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires certain persons,
including the Company's directors and executive officers, to file reports of
ownership and changes in ownership with the SEC. Based on the Company's review
of the reporting forms received by it and written representations from certain
persons that no Form 5 reports were required to be filed for those persons, the
Company believes that all such filing requirements were satisfied for FY 2001.

SOLICITATION OF PROXIES

The Company is paying the cost of preparing, printing and mailing these proxy
materials. We will reimburse banks, brokerage firms and others for their
reasonable expenses in forwarding proxy materials to beneficial owners and
obtaining their instructions. The Company has engaged Georgeson Shareholder
Communications Inc., a proxy solicitation firm, to assist in the solicitation of
proxies. We expect Georgeson's fee to be approximately $10,000 plus
out-of-pocket expenses. A few officers and employees of the Company may also
participate in the solicitation without additional compensation.

OTHER MATTERS

In addition to voting choices specifically marked, and unless otherwise
indicated by the stockholder, the proxy card confers discretionary authority on
the named proxy holders to vote on any matter that properly comes before the
Meeting which is not described in these proxy materials. At the time this proxy
statement went to press, the Company knew of no other matters which might be
presented for stockholder action at the Meeting.

STOCKHOLDER PROPOSALS FOR THE 2002 ANNUAL MEETING

To be eligible for inclusion in the Company's 2002 Proxy Statement pursuant to
Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), stockholder proposals must be sent to the Secretary of the Company at the
principal executive offices of the Company, One Post Street, San Francisco, CA
94104, and must be received no later than February 13, 2002. In order for
stockholder proposals made outside of Rule 14a-8 under the Exchange act to be
considered "timely" within the meaning of Rule 14a-4(c) under the Exchange Act,
such proposals must be sent to the Secretary of the Company at the address set
forth above and must be received no later than April 26, 2002. The Company's
Advance Notice By-Law provisions require that stockholder proposals made outside
of Rule 14a-8 under the Exchange Act must be submitted in accordance with the
requirements of the By-Laws, not later than April 26, 2002 and not earlier than
March 27, 2002.

A copy of the full text of the Company's Advance Notice By-Law provisions
referred to above may be obtained by writing to the Secretary of the Company.

ONLINE ACCESS TO ANNUAL REPORTS ON FORM 10-K AND PROXY STATEMENTS

Most stockholders can elect to view future proxy statements and annual reports
on Form 10-K over the Internet instead of receiving paper copies in the mail.
Those stockholders will be given the opportunity to consent to future Internet
delivery when they vote their proxy. For some stockholders, this option is only
available if you vote on the Internet.

If you are not given an opportunity to consent to Internet delivery when you
vote your proxy, contact the bank, broker or other holder of record through
which you hold your shares and inquire about the availability of such an option
for you.

If you consent, your account will be so noted and when the Company's Annual
Report on Form 10-K for the 2002 and proxy statement for the 2002 annual meeting
become available, you will be notified on how to access them on the Internet.
Stockholders of record may indicate their consent on this year's proxy card, and
will receive a paper proxy card for next year's annual meeting in the mail.

If you elect to receive your materials via the Internet, you can still request
paper copies by leaving a message with Investor Relations at (800) 826-9360 or
by e-mail at investors@mckhboc.com

            CHARTER OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS
                             OF MCKESSON HBOC, INC.

             (As adopted by the Board of Directors on June 9, 2000)

I. ORGANIZATION AND AUTHORITY

This Audit Committee is appointed by the Board to assist the Board in monitoring
the integrity of the Company's financial reporting process and systems of
internal controls regarding finance, accounting, and legal compliance and the
independence and performance of the Company's independent auditor and internal
audit department.

The Audit Committee has the authority to conduct any investigation appropriate
to fulfilling its responsibilities and to retain, at the Company's expense,
special legal, accounting, or other consultants or experts it deems necessary to
advise the Audit Committee in the performance of its duties.

II. COMPOSITION AND MEETINGS

The Audit Committee shall consist of from three to five members of the Board,
none of whom is a current or former officer or employee of the Corporation:

Audit Committee members shall meet the independence and experience requirements
of the New York Stock Exchange. Audit Committee members shall be appointed by
the Board.

The Audit Committee shall meet with such frequency and at such intervals as it
shall deem necessary to carry out its duties and responsibilities. The Audit
Committee Chair shall prepare and/or approve an agenda in advance of each
meeting. The Audit Committee, in its discretion, may request any officer or
employee of the Company or the Company's outside counsel or independent auditor
to attend a meeting of the Audit Committee (or any portion thereof), or to meet
with any members of the Audit Committee and to provide pertinent information as
necessary. The Audit Committee shall make regular reports to the Board.

III. DUTIES AND RESPONSIBILITIES

In carrying out its responsibilities, the Audit Committee's policies and
procedures should remain flexible, so that it may be in a position to best react
to changing circumstances or conditions. The following shall be the principal
recurring processes of the Audit Committee in carrying out its responsibilities.
These processes are set forth as a guide with the understanding that the Audit
Committee may supplement them as appropriate. The Audit Committee shall:

 1. Review and reassess the adequacy of the Audit Committee's charter at least
    annually and recommend any proposed changes to the Board for approval.

 2. Review the annual audited financial statements with management, including
    major issues regarding accounting and auditing principles and practices, as
    well as the adequacy and effectiveness of the internal controls that could
    significantly affect the Company's financial statements.

 3. Review analyses prepared by management and the independent auditor of
    significant financial reporting issues and judgments made in connection with
    the preparation of the Company's financial statements.

 4. Review with financial management and the independent auditor the interim
    financial statements prior to the filing of the Company's Quarterly Report
    on Form 10-Q. Discuss the impact of significant events, transactions, and
    changes in accounting estimates considered by the

                                       A-1
   36

    independent auditor and any other items required to be communicated by the
    independent auditor in accordance with Statement on Auditing Standards No.
    71. The Chair of the Audit Committee may represent the entire Audit
    Committee for purposes of this review.

 5. Recommend to the Board the appointment of the independent auditor, which
    firm is ultimately accountable to the Audit Committee and the Board.

 6. Receive periodic reports from the independent auditor regarding the
    auditor's independence, discuss such reports with the auditor, and if so
    determined by the Audit Committee, recommend that the Board take appropriate
    action to satisfy itself of the independence of the auditor.

 7. Evaluate the performance of the independent auditor and, if so determined by
    the Audit Committee, recommend that the Board replace the independent
    auditor.

 8. Approve the fees to be paid to the independent auditor.

 9. Review and accept, if appropriate, the independent auditor's annual audit
    plan, including the scope of the audit activities, and monitor such plan's
    progress and results during the year.

10. Discuss with the independent auditor the matters relating to the conduct of
    the audit that are required to be discussed under Statement on Auditing
    Standards No. 61.

11. Review with the independent auditor any problems or difficulties the auditor

    interest and review past or proposed transactions between the Company and
    members of management, as well as policies and procedures with respect to

While the Audit Committee has the duties and responsibilities set forth in this
charter, the Audit Committee is not responsible for planning or conducting the
audits or for determining whether the Company's financial statements are
complete and accurate and are in accordance with generally accepted accounting
principles. Similarly, it is not the duty of the Audit Committee to conduct
investigations, to resolve disagreements, if any, between management and the
independent auditor or to ensure that the Company complies with laws and
regulations and its Code of Conduct. Each member of the Audit Committee shall be
entitled to rely on (i) the integrity of those persons and organizations within
and outside the Corporation that it receives information from and (ii) the
accuracy of the financial and other information provided to the Audit Committee
by such persons or organizations absent actual knowledge to the contrary (which
shall be promptly reported to the Board of Directors).

January 1, 1997, subject to the approval of the Plan by the stockholders of the
Company; provided, that if the Plan is so approved, any election made hereunder
prior to such approval shall be deemed effective as of the date such election

determined by the Board; provided that no such termination shall affect rights
earned or accrued under the Plan prior to the date of termination.

4. Participation. Subject to the prior approval of the Committee, each member of
the Board who is not an employee of the Company or any of its subsidiaries shall
be eligible to participate in the Plan.

5. Common Stock Subject to the Plan.

(a) Subject to Section 5(b) below, the maximum aggregate number of shares
authorized to be issued under the Plan shall be 500,000. All Restricted Stock
Units issued hereunder, whether or not distributed in the form of Common Stock,
shall count against such maximum. If any options granted
                                       B-2
   40

hereunder cease to be exercisable in whole or in part, any shares subject
thereto but with respect to which such option had not been exercised, shall not
count against such maximum. As the Committee shall determine from time to time,
the Common Stock may consist of either shares of authorized but unissued Common
Stock, or shares of authorized and issued Common Stock reacquired by the Company
and held in its treasury.

(b) In the event that the Committee shall determine that any dividend or other
distribution (whether in the form of cash, stock or other property),
recapitalization, stock split, reverse stock split, reorganization, merger,
consolidation, split-up, spin-off, combination, repurchase or share exchange or
other similar corporate transaction or event affects the Common Stock such that
an adjustment is determined by the Committee to be appropriate to prevent
dilution or enlargement of the benefits or potential benefits intended to be
made available under the Plan, then the Committee may, in its sole discretion
and in such manner as it may deem equitable, adjust any or all of (i) the number
of shares of Common Stock subject to the Plan, (ii) the number of shares of
Common Stock subject to outstanding awards under the Plan, and (iii) the grant
or exercise price with respect to any option.

6. Restricted Stock Units; Deferrals.

(a) Transition Grant. As soon as practicable following January 1, 1997, each
Participant shall receive an initial grant (the "Transition Grant") of a number
of Restricted Stock Units in consideration for the termination of such
Participant's accrued benefits and rights under the Company's Director's
Retirement Program (the "Prior Plan"); provided that the Transition Grant shall
be subject to the receipt by the Company of a written release from the
Participant, in the form approved by the Committee, consenting to such
termination. The number of Restricted Stock Units granted to a Participant in
respect of the Transition Grant shall equal the Accrued Benefit (as defined
below), divided by the Fair Market Value of a share of Common Stock as of
December 31, 1996. A Participant's Accrued Benefit shall equal his or her
accrued benefit under the Prior Plan, as of December 31, 1996.

(b) Annual Grant. On the date of each Annual Meeting prior to the termination or
expiration of the Plan, beginning with the 1997 Annual Meeting, each Participant
shall receive a grant of 400 Restricted Stock Units. Effective January 27, 1999,
the annual grants of 400 Restricted Stock Units shall be discontinued.

(c) Mandatory Deferral. On each date that any portion of the Annual Retainer
would otherwise be payable to a Participant prior to the termination or
expiration of the Plan, each such Participant shall be required to defer the
receipt of an amount equal to 50% of such portion of Annual Retainer, which
amount shall be deferred in the form of Restricted Stock Units or Retainer
Options, as elected by the Participant prior to the end of the calendar year
preceding the year in which the Annual Retainer is payable. In the event that a
participant fails to make such an election with respect to any calendar year in
which he or she receives payment of an Annual Retainer, the Participant shall be
deemed to have elected to receive the Annual Retainer in the form of Restricted
Stock Units. The number of Restricted Stock Units granted to a Participant in
respect of such deferral shall equal the Annual Retainer so deferred, divided by
the Fair Market Value of a share of Common Stock as of the last trading day of
the calendar quarter immediately preceding the date such Annual Retainer would
otherwise be payable. To the extent applicable, Restricted Stock Units granted
pursuant to this paragraph shall be subject to the same terms and conditions
described in Section 6(d)(ii) below. The number of Retainer Option shares
granted to a Participant in respect of such deferral shall be determined using
the same conversion rate as employed in that year for the purpose of determining
the number of stock option shares to be granted to employees in lieu of awards
under the Company's Management Incentive Plan.

(d) Optional Deferral. All Fees (other than the portion of Annual Retainer
subject to Mandatory Deferral described above) earned by a Participant in each
Director Year prior to the termination or expiration of the Plan shall be
subject to the following payment and deferral options. Each
                                       B-3
   41

Participant may elect by written notice to the Company, in accordance with the
procedures established by the Company, to participate in such payment and
deferral options.

     (i) Cash Alternative. Unless a valid election is made in accordance with
     the procedures established by the Company, each Participant shall receive
     payment of all Fees (other than the portion of Annual Retainer subject to
     Mandatory Deferral described above) in the form of cash.

     (ii) Restricted Stock Unit Alternative. Subject to executing a valid
     election with the Company (the "RSU Election"), each Participant may elect
     to defer all or any portion of his or her Fees (other than the portion of
     Annual Retainer subject to Mandatory Deferral described above) in the form
     of Restricted Stock Units. The number of Restricted Stock Units granted
     shall equal the amount of Fees so deferred, divided by the Fair Market
     Value of the Common Stock as of the last trading day of the calendar
     quarter immediately preceding the date such Fees would otherwise be
     payable. The RSU Election (A) shall be in the form of a document executed
     by the Participant and filed with the Secretary of the Company, (B) shall
     be made before the first day of the calendar year in which the applicable
     Fees are earned and shall become irrevocable on the last day prior to the
     beginning of such calendar year, and (C) shall continue until the
     Participant ceases to serve as a director of the Company or until he or she
     terminates or modifies such election by written notice to the Company in
     accordance with the procedures established by the Company, any such
     termination or modification to be effective as of the end of the calendar
     year in which such notice is given with respect to Fees otherwise payable
     in subsequent calendar years. Any person who becomes a Participant during
     any Director Year may execute an RSU Election prior to commencing service
     on the Board with respect to Fees to be earned for the remainder of such
     year and for future Director Years in accordance with the procedures
     established by the Company.

     Each Restricted Stock Unit shall entitle the holder to, upon distribution
     thereof (A) receive a cash payment equal to the Fair Market Value of one
     share of Common Stock, or (B) have issued in his or her name one share of
     Common Stock. In either case, each such Restricted Stock Unit shall
     terminate upon distribution.

     The Company shall credit each Participant holding Restricted Stock Units
     with a number of additional Restricted Stock Units equal to any dividends
     and other distributions paid by the Company on an equivalent number of
     shares of Common Stock, as of the date such dividends or distributions are
     payable. Such additional Restricted Stock Units shall thereafter be treated
     as any other Restricted Stock Units issued under the Plan. Restricted Stock
     Units may not be sold, transferred, assigned, pledged or otherwise
     encumbered or disposed of until such time as share certificates for Common
     Stock are issued.

     Each Participant issued Restricted Stock Units shall execute a valid
     distribution election in accordance with the procedures established by the
     Committee (the "Distribution Election"). The Distribution Election shall
     indicate (A) whether distribution shall be made in the form of Common Stock
     or cash, (B) whether the distribution shall be made in a single allotment
     or in substantially equal annual installments over a period not to exceed
     ten (10) years and (C) with respect to Distribution Elections filed on or
     after October 28, 1998, the date on which the distribution shall commence
     in accordance with the next paragraph. The Distribution Election (D) shall
     be in the form of a document executed by the participant and filed with the
     Secretary of the Company, (E) shall be made no later than twelve (12)
     months prior to the distribution date and (F) shall become irrevocable
     twelve (12) months prior to the distribution date.

     With respect to a Distribution Election completed on or after October 28,
     1998, the Participant shall elect whether distributions shall commence as
     soon as practicable after (i) the first business day of January of the
     calendar year following the Participant's cessation from service as a
     director of the Company; or (ii) the first business day of January of any
     calendar year, provided that such calendar year is not later than the
     calendar year following the calendar year in which the Participant attains
     age 72. All other distributions shall commence as soon as
                                       B-4
   42

     practicable after the first business day of the January following the
     Participant's cessation from service as a director of the Company. If no
     valid Distribution Election is made, the Restricted Stock Units shall be
     distributed in a lump sum as soon as practicable after the first business
     day of January of the calendar year following the Participant's cessation
     from service as a director of the Company, in the form of cash.
     Participants who receive Restricted Stock Units shall have no rights as
     stockholders with respect to such Restricted Stock Units until share
     certificates for Common Stock are issued. Notwithstanding any provision to
     the contrary, any fractional shares of Common Stock issuable hereunder
     shall be paid in cash.

     Upon the occurrence of a Change in Control, Common Stock to be issued in
     respect of all Restricted Stock Units shall be immediately distributed.

     (iii) DCAP II Alternative. Subject to executing an election in accordance
     with the procedures established by the Company and the terms of DCAP II,
     each Participant may elect to defer all or any portion of his or her Fees
     (other than the portion of Annual Retainer subject to Mandatory Deferral
     described above) under DCAP II.

     (iv) Retainer Option Alternative. Subject to executing an election in
     accordance with the procedures established by the Company, each Participant
     may elect to receive the portion of Annual Retainer not subject to
     Mandatory Deferral, as described in Section 6(c) above, in the form of
     Retainer Options. The number of Retainer Option shares granted to a
     Participant with respect to such deferral shall be determined in the manner
     described in Section 6(c) above.

7. Stock Options.

(a) Discretionary Grants. The Committee may, in its sole discretion, grant
options to purchase Common Stock to Participants, pursuant to such terms and
conditions that it may deem advisable, so long as not inconsistent with Section
7(d) below or any other terms of this Plan.

(b) Formula Grants. Each Participant then serving as a non-employee director of
the Company shall automatically receive, on the date of each January meeting of
the Board, an option to purchase 10,000 shares of Common Stock (subject to
adjustment as provided in Section 5(b) above); provided, however, that a
Participant who is elected to the Board after the January meeting of the Board
shall be granted, as of the date of election, a prorated number of options with
respect to the initial year of participation in the Plan, based on the number of
full calendar quarters remaining in the calendar year in which the Participant
is elected to the Board. The options granted pursuant to this Section 7(b) shall
be immediately exercisable in full and have an option term of ten years.

(c) Retainer Option Grants. At the same time that the Company makes stock option
grants annually to eligible employees, each Participant who has made an election
to receive a Retainer Option pursuant to Section 6(c) or 6(d)(iv) with respect
to all or any portion of the Annual Retainer to be paid in such year shall be
granted an option to purchase that number of shares of Common Stock determined
pursuant to Section 6(c) and/or Section 6(d)(iv), as applicable. The terms of
such Retainer Options shall be as prescribed by the Committee, so long as such
terms are not inconsistent with Section 7(d) below or any other terms of this
Plan.

(d) Terms and Conditions of Options. Except as provided in Section 7(b) above,
the following terms and conditions shall apply to all options granted to
Participants under the Plan.

     (i) The exercise price of each option shall not be less than the Fair
     Market Value of the Common Stock covered by the option on the date the
     option is granted.

     (ii) Each option granted pursuant to the Plan shall be evidenced by a
     written grant agreement (the "Agreement") executed by the Company and the
     person to whom such option is granted which shall provide such terms and
     conditions as the Committee may determine, in its sole discretion, so long
     as not inconsistent with the terms of this Plan.

     (iii) The term of each option shall be for no more than ten years.

                                       B-5
   43

     (iv) The Agreement may contain such other terms, provisions, and conditions
     as may be determined by the Committee (not inconsistent with this Plan).
     Unless otherwise provided in the Agreement and excluding options granted
     under paragraph (b) above, the Committee may, in its sole discretion,
     extend the post-termination exercise period with respect to an option (but
     not beyond the original term of such option).

     (v) Payment of the purchase price upon exercise of any option shall be made
     in cash; provided that the Committee, in its sole discretion, may permit an
     option holder to pay the option price by such other method that it may deem
     appropriate, including, without limitation, by tendering to the Company
     shares of Common Stock owned by the option holder, and having a Fair Market
     Value equal to the option price. Such stock surrender method may permit an
     election by the option holder to have the unrealized gain with respect to
     the option denominated in stock units (based on the fair market value of a
     share of Common Stock on the date of exercise) and paid in shares of Common
     Stock at the time specified by the Participant at the time of making the
     stock surrender option gain deferral election. During the deferral period
     each such stock unit shall be credited with additional stock units equal to
     any dividends or other distributions paid by the Company on an equivalent
     number of shares of Common Stock, as of the date such dividends or
     distributions are payable. Stock units may not be sold, transferred,
     assigned, pledged or otherwise encumbered or disposed of until such time as
     share certificates for Common Stock are issued.

     (vi) All such options shall be designated as stock options which do not
     qualify under Section 422 of the Internal Revenue Code of 1986, as amended.

     (vii) Unless otherwise provided in an Agreement, options granted under the
     Plan will become immediately and fully vested and exercisable upon the
     occurrence of a Change in Control.

8. Administration. The Plan shall be administered by the Committee. The
Committee shall have full power to interpret the Plan and formulate additional
details and regulations for carrying out the Plan. Any decision or
interpretation adopted by the Committee shall be final and conclusive.

9. No Right to Serve. Nothing in the Plan shall confer upon any Participant the
right to remain in service as a member of the Board.

10. Amendment and Termination. The Board at any time may amend or terminate the
Plan; provided that any such amendment or termination does not adversely affect
the rights of any Participant.

11. Governing Law. The validity, construction and effect of the Plan and any
such actions taken under or relating to the Plan shall be determined in
accordance with the laws of the State of California.

12. Notices. All notices under this Plan shall be sent in writing to the
Secretary of the Company. All correspondence to the Participants shall be sent
in writing to the Participant at the address which is their recorded address as
listed on the most recent election form or as specified in the Company's
records.

13. Unfunded Status of Awards. The Plan is intended to constitute an "unfunded"
plan for incentive and deferred compensation. Nothing contained hereunder shall
give any Participant any rights that are greater than those of an unsecured
general creditor of the Company.
