              ---------------------------------------------------

                        Amended as of January 27, 1999
                        ------------------------------


A.   PURPOSE
     -------

     This Plan is established to further enhance the Company's ability to
attract and retain executive personnel.

B.   ERISA PLAN
     ----------

     This Plan is an unfunded deferred compensation program for a select group
of management employees of the Company.  The Plan therefore is covered by Title
I of ERISA except that it is exempt from Parts 2, 3, and 4 of Title I of ERISA.

C.   PARTICIPATION
     -------------

     1.   Eligibility to Participate.  The Compensation Committee may, at its
          --------------------------
discretion, and at any time, and from time to time, select Company executives
who may elect to participate in this Plan ("Eligible Executives"). Selection of
Eligible Executives may be evidenced by the terms of the executive's employment
contract with the Company, or by inclusion among the persons specified by the
Compensation Committee.

     The Compensation Committee may, at its discretion, and at any time, and
from time to time, designate additional Eligible Executives and/or provide that
executives previously designated are no longer Eligible Executives.  If the
Compensation Committee determines that an executive is no longer an Eligible
Executive, he or she shall remain a Participant in the Plan until all amounts
credited to his or her Account prior to such determination are paid out under
the terms of the Plan (or until death, if earlier).

     2.   Election to Participate by Eligible Executives.   Each Eligible
          ----------------------------------------------
Executive may become a Participant in the Plan by electing to defer compensation
in accordance with the terms of this Plan.  An election to defer shall be in
writing, shall be irrevocable and shall be made at the time and in the form
specified by the Administrator.  On electing to defer compensation under this
Plan, the Eligible Executive shall be deemed to accept all of the terms and
conditions of this Plan.

          All elections to defer amounts under this Plan shall be made pursuant
to an election executed and filed with the Administrator before the amounts so
deferred are earned. All elections to defer 1985 compensation shall be executed
and filed with the Administrator no

                                                                          Page 1


later than September 15, 1985, or on any later date in 1985 (no later than
September 22, 1985) if the election is to defer 1985 compensation earned after
such later date.

     3.   Notification of Participants.  The Administrator shall annually notify
          ----------------------------
each Eligible Executive that he or she may participate in the Plan for the next
Year.

     4.   Relation to Other Plans.
          -----------------------

          a.   DCAP.  An Eligible Executive may participate in this Plan and may
               ----
also participate in the McKesson HBOC, Inc. Deferred Compensation Administration
Plan. No amounts may be deferred under this Plan which have been deferred under
the McKesson HBOC, Inc. Deferred Compensation Administration Plan or any other
plan of the Company.

          b.   Other Plans.  For all other benefit programs maintained by the
               -----------
Company, amounts deferred by an Eligible Executive under this Plan shall, to the
extent relevant, be treated in the same manner as amounts deferred under the
McKesson HBOC, Inc. Deferred Compensation Administration Plan.

D.   AMOUNTS OF DEFERRAL
     -------------------

     1.   Minimum Deferral.  The minimum amount of compensation that may be
          ----------------
deferred by an Eligible Executive under this Plan for 1985 is one month's
salary. The minimum amount that an Eligible Executive may defer for 1986 and
later Years is $10,000.

     2.   Maximum Deferral.
          ----------------

          a.   1985.  The maximum amount of compensation which an Eligible
               ----
Executive may defer under this Plan for 1985 shall be his or her salary earned
from September 16, 1985 through December 15, 1985.

          b.   Years After 1985.  The maximum amount of compensation which an
               ----------------
Eligible Executive may defer under this Plan for any Year after 1985 is (i)
twenty-five percent (25%) of the amount of such Eligible Executive's base salary
for such Year, calculated at the annual base salary rate in effect on January 1
of such Year, and (ii) the amount of any annual bonus award and/or any Long-Term
Incentive Plan Award determined and payable to him or her in such Years.

     3.   As Deferrals After 1986.  Eligible Executives may not defer
          -----------------------
compensation under this Plan for any Year after 1986.

E.   PAYMENT OF DEFERRED COMPENSATION
     --------------------------------

     1.   Book Account and Interest Credit.  Compensation deferred by an
          --------------------------------
Eligible Executive under the Plan shall be credited to a separate bookkeeping
account for such Eligible Executive (the "Account"). (Separate Accounts or Sub-
Accounts may be established for each Year for which the Eligible Executive
elects to defer compensation.) Interest shall be credited to

                                                                          Page 2


each Account for each Year at a rate equal to 6% plus the Moody's Corporate Bond
Yield Average--Monthly Average Corporates as published by Moody's Investors
Service, Inc. (or any successor thereto) for December of each Year prior to the
Year in which such interest rate is credited. Each Account balance shall be
compounded monthly, in a consistent manner as determined by the Administrator,
at the appropriate rate of interest provided for under the Plan.

     2.   Reduced Interest Rate for Participants Who Leave Before Approved
          ----------------------------------------------------------------
Retirement. If a Participant's employment with the Company is terminated for any
- ----------
reason whatsoever prior to the date of his or her Approved Retirement (except on
death or disability), the interest rate which shall be credited to his or her
Account shall be the rate specified in Section E.1, above, for the period up to
and including the date his or her employment terminates and thereafter shall be
the rate specified in Section E.1, above, less 6 percentage points per annum.
Notwithstanding the foregoing, the Compensation Committee may, in its
discretion, credit the Account of any Participant whose employment is terminated
at an interest rate up to the plan maximum for years and portions thereof,
following the date on which the Participant's employment terminates. This
reduced rate shall not apply to any amounts which have been distributed under
paragraph b of Section E.3 (relating to interim distributions) prior to such
termination.

     3.   Length of Deferral.
          ------------------

          a.   Basic Deferral Period.  An Eligible Executive shall elect in
               ---------------------
writing, and file with the Administrator, at the same time as such Eligible
Executive makes any election to defer compensation, the period of deferral with
respect to such election. Once such an election is made, an Eligible Executive
may alter the timing of receipt of benefits under the election, provided that
such alteration is made at least one year prior to the earliest date the
Participant could have received payment of benefits under the Plan under the
previous election and does not provide for the receipt of such amounts earlier
than one year from the date of the alteration. Payment of amounts deferred and
interest credited thereon must begin no later than the January following the
year in which the Eligible Executive reaches age 72, subject to the minimum
required period of deferral, which is 5 years.

          b.   Interim Distributions.  An Eligible Executive may elect to have
               ---------------------
up to 100% of the amount of compensation deferred in any Year, plus credited
interest, paid to him or her prior to age 65. No election made pursuant to this
paragraph may provide for payments of deferred compensation and interest
credited thereon until at least 5 years from the date of the deferral which is
the subject of the election.

               Any election under this paragraph shall be made in writing and
filed with the Administrator at the same time as any election to defer
compensation.

          c.   Benefits Payable on Death.  See Section F for the payment of
               -------------------------
benefits on death of a Participant.

                                                                          Page 3


     4.   Method of Payment.
          -----------------

          a.   Election.  An Eligible Executive shall elect in writing, and file
               --------
with the Administrator, at the same time as any election to defer compensation,
a method of payment of benefits under the Plan.

          b.   Alternative Methods Available--Basic Deferral Period. The
               ----------------------------------------------------
following methods of benefit payment may be elected by an Eligible Executive for
amounts payable after deferral under paragraph a. of Section E.3 relating to the
basic deferral period:

               (i)  Payment of amounts credited to the Participant's Account in
any specified number of approximately equal annual installments (not in excess
of 10). In the case of installment payments, interest at the appropriate rate
shall be credited on all amounts remaining in a Participant's Accounts.

               (ii) Payment of the amount credited to the Participant's Account
in a single sum.

          c.   Alternative Methods Available--Interim Distributions.  The
               ----------------------------------------------------
following methods of benefit payment may be elected by an Eligible Executive for
interim distributions under paragraph b of Section E.3:

               (i)  Payment in any specified number of approximately equal
annual installments (not in excess of 10). In the case of installment payments,
interest at the appropriate rate shall be credited on all amounts remaining in a
Participant's Accounts.

               (ii) Payment in a single sum.

     5.   Date Payments Begin.
          -------------------

          a.   After Basic Deferral Period. Payments shall begin (or, in the
               ---------------------------
case of payments to be made in a single sum, shall generally be made) on the
first day of the month after the basic deferral period ends under paragraph a.
of Section E.3, but, in any event, must begin no later than the January
following the year in which the Eligible Executive reaches age 72.

          b.   Interim Distributions.  Payments shall begin (or, in the case of
               ---------------------
payments to be made in a single sum, shall be made) on the date previously
elected by the Participant for interim distributions.

          c.   Upon Termination of Employment.  Notwithstanding paragraphs 5.a.
               ------------------------------
and b., above, if an Eligible Executive's employment with the Company terminates
before Retirement, the Participant shall receive a single, lump sum payment of
the entire amount credited to the Participant's Account in the January following
such termination of employment.

                                                                          Page 4


F.   BENEFITS ON DEATH
     -----------------

     1.   Death After Payments Have Begun.
          -------------------------------

          a.   Basic Deferral. If a Participant dies after payments from his or
               --------------
her Account have begun (not taking into account interim distributions under
paragraph b of Section E.3), and if installment payments are being made, the
remainder of the amounts credited to the Participant's Account shall be paid to
his or her Beneficiary at the same time and in the same manner as they would
have been paid had the Participant survived until all amounts were paid out. If
installment payments have not been elected, amounts shall be paid as provided
for under any other form of benefit payment elected.

          b.   Interim Distributions.  If a Participant dies after interim
               ---------------------
distributions under paragraph b of Section E.3 have begun, the interim
distributions shall be paid to the Participant's Beneficiary at the same time
and in the same manner as they would have been paid had the Participant
survived.

     2.   Death Before Payments Have Begun.  If a Participant dies before
          --------------------------------
payments (except interim distributions) have begun, the amount credited to his
or her Account shall be paid to his or her Beneficiary beginning at the time
payments would have been made under paragraph a. of Section E.3. (relating to
basic deferrals) or at such earlier time as the Participant elected. Elections
shall be made in writing and filed with the Administrator at the time of any
election to defer compensation. Benefits shall be paid in one of the methods
specified in paragraph b. of Section E.4. If the Participant's employment with
the Company is terminated for any reason whatsoever prior to the date of
Approved Retirement (except on death or disability), the rate of interest which
shall be credited to his or her Account for the period after such termination
shall, of course, be the lower rate specified in Section E.2., unless the
Compensation Committee otherwise determines as provided in that Section E.2. The
Administrator, at his or her discretion, may distribute all benefits to a
Beneficiary in a single payment if the present value of the benefits payable to
a Participant or Beneficiary is less than $5,000.

     3.   Designation of Beneficiary.  A Participant may designate any person or
          --------------------------
entity as his or her Beneficiary, but may not designate more than one person or
any person that is not a natural person without the approval of the
Administrator. Designation shall be in writing and shall become effective only
when filed with (and, if appropriate, approved by) the Administrator. Such
filing must occur before the Participant's death. A Participant may change the
Beneficiary, from time to time, by filing a new written designation with (and,
if appropriate, approved by) the Administrator. If the Participant is married
any Beneficiary designation which does not designate the Participant's spouse to
receive at least one-half of the Participant's Account shall only become
effective when approved in writing by the Participant's spouse.

G.   SOURCE OF PAYMENT
     -----------------

     Amounts paid under this Plan shall be paid from the general funds of the
Company, and each Participant and his or her Beneficiaries shall be no more than
unsecured general creditors of

                                                                          Page 5


the Company with no special or prior right to any assets of the Company for
payment of any obligations hereunder. Nothing contained in this Plan shall be
deemed to create a trust of any kind for the benefit of any Participant or
Beneficiary, or create any fiduciary relationship between the Company and any
Participant or Beneficiary with respect to any assets of the Company.

H.   MISCELLANEOUS
     -------------

     1.   Withholding. Each Participant and Beneficiary shall make appropriate
          -----------
arrangements with the Company for the satisfaction of any federal, state, or
local income tax withholding requirements and Social Security or other
employment tax requirements applicable to the payment of benefits under this
Plan. If no other arrangements are made, the Company may provide, at its

     2.   No Assignment. The benefits provided under this Plan may not be
          -------------

claimants and from all orders, decrees, levies, garnishments or executions.

     3.   Insurance Examinations.  As a condition of participation in this Plan,
          ----------------------

examination and provide such information as may be required by the Company with
respect to an insurance contract on the Eligible Executive's life, and shall
authorize the Company to purchase life insurance on his or her life.

     4.   Applicable Law; Severability.  The Plan hereby created shall be
          ----------------------------
construed, administered, and governed in all respects in accordance with ERISA
and the laws of the State of California to the extent that the latter are not
preempted by ERISA. If any provision of this instrument shall be held by a court
of competent jurisdiction to be invalid or unenforceable, the remaining
provisions hereunder shall continue to be effective.

I.   ADMINISTRATION OF THE PLAN
     --------------------------

     1.   In General. The Plan Administrator shall be the Senior Vice President,
