401(a)(17)  and  415(d)(1) of the Code. In  determining  the  Compensation  of a
Participant for purposes of this  limitation,  the family  aggregation  rules of
Code Section  414(q)(6)  shall apply to Five Percent  Owners and Top-Ten  Highly
Compensated  Employees.  However, for this purpose, the term Family Member shall
include only the spouse of the  Participant  and any lineal  descendants  of the
Participant  who have not attained age 19 before the close of the Plan Year.  If
the maximum  compensation  limitation would otherwise be exceeded as a result of
the  application  of  the  family  aggregation  rules,  then,  for  purposes  of
determining  benefits under the Plan, the limitation shall be prorated among the
affected family members in proportion to each member's  compensation  determined
under  this  section  prior  to  the  application  of the  maximum  compensation
limitation.   The  family  aggregation  rules  of  Code  Section  414(q)(6)  are
incorporated  herein by  reference.  (See also,  Section  414  Compensation  and
Section 415 Compensation, defined below.)

Participant for the Plan Year. Provided,  however,  that in the case of a Highly
Compensated  Employee who is eligible to participate in two or more Code Section
401(k) plans of the Employer to which salary  reduction  contributions  or other
elective  contributions  may be made,  all such  contributions  on behalf of the

1.15 "Eligibility Computation Period" means a 12-consecutive-month period during
which an Employee completes not less than 1,000 Hours of Service,  measuring the

          PriceCostco 401(k) Plan for California Union Employees   Page 5





     (e) The determination of who is a  Highly-Compensated  Employee,  including
the  determinations  of the number and  identity  of  Employees  in the top paid

(a)(2),  there shall be excluded all  Employees  who (i) have not  completed six
months of Service with the Employer,  (ii) normally work less than 17- 1/2 hours

be credited to the Employee for the Plan Year in which the Employee performs the
duties, irrespective of when paid;

     (b) Each hour for which back pay, irrespective of mitigation of damages, is
either  awarded or agreed to by the  Employer or an  Affiliated  Company.  Hours
under this  subsection  shall be credited to the  Employee  for the Plan Year to
which the award or the agreement  pertains rather than to the Plan Year in which
the award, agreement, or payment is made; and

     (c) Each hour for which  the  Employer  or an  Affiliated  Company,  either
directly or  indirectly,  pays an Employee or for which the Employee is entitled
to payment  (irrespective of whether the employment  relationship is terminated)
for reasons other than for the performance of duties during a Plan Year, such as
leave of absence, vacation, holiday, illness, incapacity (including disability),
layoff,  jury duty,  or  military  duty.  Hours under this  subsection  shall be
credited to the Plan Year in which the Employee is paid,  the  Employee  becomes
entitled to  payment,  or the  payment  becomes  due,  whichever  occurs  first.
Notwithstanding the preceding provisions of this subsection,  no credit shall be
given for:

expiration  of any  Military  Leave,  Approved  Absence,  Maternity or Paternity
Leave, sick leave,  vacation, or within three days after recall from a temporary

and elective  contributions  on behalf of the  Participant  for the same taxable
year  under  all cash  and  deferred  arrangements  described  in Code  Sections

the  purchase of an annuity  contract  described  in Section  403(b) of the Code

Employee).

     Section  415  Compensation  for any  Limitation  Year  is the  compensation
actually  paid or made  available  in gross  income  during such year.  However,
Section  415  Compensation  for a  Participant  who is  permanently  and totally

Participant  would have received for the Limitation  Year if the participant had
been  paid  at  the  rate  of  compensation  paid  immediately  before  becoming
permanently  and  totally  disabled.   Notwithstanding  the  foregoing,  imputed
compensation  may be taken into account only if the  Participant is not a Highly

Participant are nonforfeitable when made. Furthermore, under the Act, the annual
Section  415  Compensation  of any  Participant  shall not exceed  $150,000,  as

for a  blind  Participant  age 55 and  over,  the  inability  to  engage  in the
Participant's  usual  occupation.  Total  Disability  shall be  evidenced by the
Participant's  eligibility  for  Social  Security  disability  benefits,  and  a
disabled  Participant must furnish proof  satisfactory to the Plan Administrator
of a determination by Social Security that the Participant is entitled to Social
Security disability benefits.

Participant has an Account balance in the Plan.  However,  active  participation
shall cease when a Participant  terminates employment with the Employer.  Active
participation  shall also cease if a Participant's  Eligible  Employment ceases,

provisions of Section 2.4. Such a Participant  may become an active  Participant
again as of the date he or she  returns to  Eligible  Employment.  In  addition,

Participant on the date of  re-employment.  Any other Employee whose  employment
terminates  and who is  subsequently  re-employed  shall become a Participant in
accordance with the normal provisions of Section 2.1.

2.4        INELIGIBLE EMPLOYEE STATUS

If a  Participant  does not  terminate  employment  but  becomes  an  Ineligible
Employee,  the Plan Administrator  shall limit that  Participant's  share of the
allocation of Employer  contributions  and Participant  forfeitures,  if any, to
relate to the Participant's Compensation paid by the Employer for services while
the Participant was in Eligible Employment.  However, during the period that the
Participant  is an Ineligible  Employee,  his or her Account  shall  continue to
share fully in

         PriceCostco 401(k) Plan for California Union Employees   Page 13

the  requirements of Section 2.1 and would have been a Participant had he or she
been in  Eligible  Employment  during  his or her  period  of  Service  with the
Employer.

                             EMPLOYER CONTRIBUTIONS

     (a) Salary Deferral Contribution.  For each payroll period or other similar
period  during the Plan Year,  the Employer  shall  contribute  an amount to the
Account of each  Participant  equal to the  Salary  Deferral  Contribution  made
pursuant to such Participant's Salary Deferral Agreement for such Plan Year.

     (b)  Matching  Contribution.   For  each  Plan  Year,  the  Employer  shall
contribute  an amount to the  Account  of each  Participant  equal to 50% of the
Salary Deferral Contributions made pursuant to the Participant's Salary Deferral
Agreement for such Plan Year. However, for purposes of determining the amount of
the Employer's Matching  Contribution,  the Salary Deferral Contribution made by
the  Employer  on  behalf  of  each  Participant  in  excess  of  $250  of  such
Participant's  Compensation in any Plan Year shall be  disregarded,  so that the
maximum  Matching  Contribution  for any  Participant  in any Plan Year shall be
$125. The amount of the Matching Contribution may be amended from time to time.

     (c)  Qualified  Non-Elective   Contribution.   The  Employer  may,  in  its
discretion, make a Qualified Non-Elective Contribution in order to help meet the
ADP test described in Section 4.2. Such contribution shall be allocated first to
those   Participants  with  the  lowest  Deferral   Percentage  or  Contribution
Percentage,  as applicable,  in the minimum amount necessary to meet the test in
question or to cause such  Participants'  Deferral  Percentages or  Contribution
Percentages to equal the Deferral or  Contribution  Percentages of  Participants
with the next lowest  percentages,  whichever  occurs first.  Then the remaining
contribution  shall be allocated  to the group with the next lowest  Deferral or
Contribution  Percentage,  including  those  Participants  brought  up  to  such
percentage by the previous  allocation,  in the minimum amount necessary to meet
the test in question or to cause such  percentages  to equal the  percentage  of
Participants  with the next lowest  percentage.  This process shall be continued
until  the  applicable  test is met and the  contribution  is  allocated  in its
entirety. All Qualified Non-Elective  Contributions allocated to a Participant's
Account shall be immediately  Nonforfeitable  and subject to the  limitations on
withdrawal for Salary  Deferral  Contributions  as described in Section 4.11 and
Treasury Regulation l.401(k)-1(b)(5).

     (d)  Form  of   Contribution.   All   Matching   Contributions,   Qualified

cash.

     (e)  Right to Amend.  The Plan may be  amended  at any time to  change  the
amount of the Matching  Contributions  or  described  in this Section 3.1.  Such
amendments shall be made in any

         PriceCostco 401(k) Plan for California Union Employees   Page 14





manner  permitted by law by the Employer  (acting through its Board of Directors
or through the officers  and/or  directors  to whom the Board of  Directors  has
delegated  authority to amend the plan) or by the  Committee,  to the extent the
Committee has authority to amend the Plan. The change shall become  effective by
announcement of the change to Participants,  by an appropriate resolution, or by
authorized signatures on an amendment or an amended and restated document.
 Such a change  shall be  effective  at the  earliest  of the date the change is
communicated to Participants, the date the amendment is adopted, or the date the
amendment is signed.

3.2        RETURN OF CONTRIBUTION

The  Trustee,  upon  written  request  from the  Employer,  shall  return to the
Employer  the amount of the  Employer's  contribution  made by the  Employer  by
mistake of fact or the amount of the  Employer's  contribution  disallowed  as a
deduction  under  Section  404 of the Code.  The  Trustee  shall not  return any
portion of the Employer's contribution under the provisions of this section more
than one year after:

     (a) The date of  determination  that the Employer made the  contribution by
mistake of fact; or

     (b) The date of disallowance of the contribution as a deduction.

The  Trustee  shall  not  increase  the  amount of the  Employer's  contribution
returnable under this section for any earnings attributable to the contribution,
but the Trustee shall  decrease the Employer's  contribution  returnable for any
losses  attributable  to it. The Trustee may require the  Employer to furnish it
whatever  evidence the Trustee deems  necessary to enable the Trustee to confirm
the amount the Employer has requested be returned is properly  returnable  under
Section 403(c) of the Act.

3.3        TIME OF PAYMENT OF CONTRIBUTION

The Employer shall pay its contribution to the Trustee for each Plan Year within
the time  prescribed  (including  extensions) by the Code for filing its federal

distribution  occurs after the 15th of the month.  Notwithstanding the preceding
sentence,  the Plan  Administrator  may use any  other  reasonable  method  that
reflects  income or loss on such Excess  Deferrals.  A  Participant's  claim for
Excess  Deferrals  shall  be in  writing  and  shall  be  submitted  to the Plan
Administrator  no later than March 1 of the year  following the calendar year in
which such Excess Deferrals were made.

4.2        DEFERRAL LIMITATIONS

(a) ADP Discrimination Tests for Salary Deferral Contributions. In order for the
discrimination standards of Internal Revenue Code Section 401(k) to be satisfied
in any Plan Year, the Actual Deferral  Percentage (ADP) for Participants who are
Highly  Compensated  Employees and the ADP for  Participants  who are not Highly
Compensated Employees must satisfy one of the following tests:

          (1) The ADP for  Participants who are Highly  Compensated  Employees
is not more than the ADP for  Participants  who are not  Highly  Compensated
Employees multiplied by 1.25; or

           (2) The excess of the ADP for Participants who are Highly Compensated
Employees over the ADP for Participants who are not Highly Compensated Employees
is not more than two percentage  points,  and the ADP for  Participants  who are
Highly  Compensated  Employees is not more than the ADP for Participants who are
not Highly Compensated Employees multiplied by 2.

           Compliance with the discrimination standards set forth above shall be
determined in accordance with Code Section 401(k), as amended from time to time,
and any  related  laws and  regulations  as may be in effect  from time to time.
Under those rules,  if this plan is aggregated  with any other plan or plans for
purposes of the  nondiscrimination  standards of Code  Section  401(a)(4) or the
minimum  coverage  requirements  of Code  Section  410(b)  (other  than  Section
410(b)(2)(A)(ii)), all elective contributions made under all such plans shall be
treated as if made under a single plan.  In  addition,  if two or more plans are
permissively aggregated for purposes of the nondiscrimination  standards of Code
Section  401(k),  the  aggregated  plans  must  satisfy  the   nondiscrimination
standards of Section 401(a)(4) and the minimum coverage  requirements of Section
410(b) as though they were a single plan.

     (b)   Abatement  of  Salary   Deferral   Contributions.   Salary   Deferral
Contributions  credited  to the  account of a  Participant  may be abated to the
extent deemed necessary by the Employer to meet the discrimination  standards of
Code Sections  401(a)(4) and 401(k);  to insure that the Annual Additions to the
Account of a Participant  do not exceed the maximum  limitations of Code Section
415, as expressed in Section 5.3 of the Plan;  or to insure that the  Employer's
contribution  does not exceed the maximum amount  deductible from the Employer's
income under Code Section 404. Any excess amounts, plus any income and minus any
loss  allocable  thereto,  shall be  returned  to the  Participant  as salary if
possible within two and one-half months

         PriceCostco 401(k) Plan for California Union Employees   Page 16





after the close of the Plan Year and in all  events by the end of the  following
Plan Year.  The income  allocable to an excess  contribution  shall include both
income for the Plan Year for which the excess contributions were made and income
for the period between the end of the Plan Year and the date of distribution.

           Such distribution  shall be made to Highly  Compensated  Employees on
the basis of the respective portions of the Excess Contributions attributable to
each. The Excess  Contribution of a Highly Compensated  Employee for a Plan Year
is to be determined by the following  leveling method,  under which the Deferral
Percentage  of  the  Highly  Compensated  Employee  with  the  highest  Deferral
Percentage is reduced to the extent required to:

           (1) Enable the plan to satisfy the discrimination tests; or

           (2) Cause such Highly Compensated  Employee's  Deferral Percentage to
equal  the  ratio of the  Highly  Compensated  Employee  with  the next  highest
Deferral Percentage.

           This  process  shall  be  repeated   until  the  plan  satisfies  the
discrimination  tests. Any salary reduction  agreement shall be deemed to direct
and authorize the Employer to abate a Participant's salary reduction account and
to return any abated amounts as specified above.

4.3        FAMILY AGGREGATION RULES

For purposes of determining  the Deferral  Percentage of a Participant  who is a
Five  Percent  Owner  or  a  Top-Ten  Highly-Compensated  Employee,  the  salary
deferrals (and Qualified  NonElective  Contributions  and if treated as elective
deferrals  for  purposes  of the ADP  test),  and the 414  Compensation  of such
Participant  shall  include  the  salary  deferrals  (and,  if  applicable,  the
Qualified  Non-Elective  Contributions),  the and the  414  Compensation  of the
Family Members of such Highly Compensated Employee.  The affected Family Members
of such Highly Compensated  Employees shall otherwise be disregarded as separate
employees both in determining the ADP of Participants who are Highly Compensated
Employees  and in  determining  the  ADP of  Participants  who  are  not  Highly
Compensated Employees.

The  determination  of the amount of any Excess  Contribution  for a Participant
subject to these  family  aggregation  rules  shall be made as  follows,  unless
applicable Treasury Regulations provide otherwise:

           (1) If the  Highly  Compensated  Employee's  Deferral  Percentage  is
determined by combining the  contributions and compensation of only those Family
Members who are Highly  Compensated  Employees  themselves without regard to the
family aggregation rules, then the Deferral  Percentage is reduced in accordance
with the leveling method described above, and the Excess Contributions or Excess
Aggregate  Contributions  for the  family  unit are  allocated  among the family
members in proportion to the  contributions of each family member that have been
combined.

           (2) If the  Highly  Compensated  Employee's  Deferral  Percentage  is
determined by combining the  contributions  and  compensation of Family Members,
some of whom are not themselves Highly Compensated Employees,  then the Deferral
Percentage is reduced in

         PriceCostco 401(k) Plan for California Union Employees   Page 17





accordance  with the leveling  method but not below the Deferral  Percentage  of
eligible  Family  Members  who  are not  Highly  Compensated  Employees.  Excess
Contributions  are  determined by taking into account the  contributions  of the
eligible family members who are Highly  Compensated  Employees without regard to
the family  aggregation  rules and are  allocated  among such family  members in
proportion  to  their  contributions.  If  further  reduction  of  the  Deferral
Percentage is required,  Excess Contributions  resulting from this reduction are
determined  by taking into  account the  contributions  of all  eligible  family
members and are  allocated  among such  family  members in  proportion  to their
contributions.

4.4        EXCISE TAXES

Under  current law, the Employer  shall be liable for an excise tax in an amount
equal to 10% of the  amount of Excess  Contributions  that have not been  either
distributed  to the  Participants  or forfeited  within two and one-half  months
following the end of the Plan Year.

4.5        LIMITED DISTRIBUTIONS OF SALARY DEFERRAL AND QUALIFIED
           NON-ELECTIVE CONTRIBUTIONS

Salary Deferral Contributions,  Qualified Non-Elective Contributions, and income
allocable thereto are not normally distributable to a Participant or Beneficiary
earlier  than  upon  termination  of  employment,  death,  or Total  Disability.
However, such amounts may also be distributed upon:

     (a)  Termination of the Plan without the  establishment  of another defined
contribution  plan,  other than an  employee  stock  ownership  plan  within the
meaning of Sections 409 or 4975(e) of the Code or a simplified  employee pension
plan as defined in Section 408(k) of the Code;

     (b)  The  disposition  by a  corporation  to an  unrelated  corporation  of
substantially  all of the assets (within the meaning of Section 409(d)(2) of the
Code)  used  in a  trade  or  business  of such  corporation  if the  transferor
corporation continues to maintain this Plan after the disposition, but only with
respect to Employees who continue employment with the corporation acquiring such
assets;

     (c)  The  disposition  by a  corporation  to an  unrelated  entity  of such
corporation's  interest in a subsidiary (within the meaning of Section 409(d)(3)
of the Code) if the transferor corporation continues to maintain this Plan after
the disposition, but only with respect to Employees who continue employment with
such subsidiary;

     (d) The attainment of age 59-1/2 ; or

     (e) The hardship of the Participant as described in Section 9.8.

                             ALLOCATION TO ACCOUNTS

5.1        CONTRIBUTION ALLOCATION

     (a) The Salary Deferral  Contribution of the Employer for a Plan Year shall
be allocated to each  Participant's  Salary Deferral  Account in accordance with
the Salary  Deferral  Agreement  entered  into by the  Participant  so that each
Account shall be credited with the amount by which that Participant's salary was
reduced.

     (b) The Employer's Matching Contribution payable on behalf of a Participant
for a Plan Year shall be allocated to the  Participant's  Employer  Contribution
Account in the amount payable under Section 3.1(b).

     (c) The Qualified  Non-Elective  Contributions,  if any  contributions  are
designated   as  such  by  the   Employer,   shall  be   allocated  as  soon  as
administratively  possible to the Employer Qualified  Non-Elective  Contribution
Account  of  those  Participants  who  are  entitled  to an  allocation  of such
Qualified Non-Elective Contributions for that Plan Year under Section 3.1(c).

     (d) In no event shall the Employer make a contribution  to a  Participant's
Account if the contribution  would cause the  Participant's  Annual Addition for
that Plan Year to exceed the maximum  annual  limitations  described in Sections
5.3 and 5.4.

5.2        ALLOCATION OF INVESTMENT INCOME (OR LOSS)

All  contributions  to the  Accounts  of each  Participant  in the Plan shall be
reflected  in units of each  Investment  Fund and in shares of  Employer  Stock,
according  to the  investments  elected by the  Participant.  The net income (or
loss) of each Investment Fund,  including the increase (or decrease) in the fair
market value of the assets of the Investment  Fund and of the Shares of Employer
Stock and from any  administrative  expenses charged to the Trust Fund, shall be
determined as of each Valuation Date and shall  determine the value of the units
of each Investment Fund and the value of the shares of Employer Stock.

5.3        LIMITATION ON ANNUAL ADDITIONS

The Annual Addition to the Account of any Participant for a Plan Year under this
Plan and all other defined contribution plans maintained by the Employer may not
exceed the "Maximum Permissible Amount" described below, in accordance with Code
Section 415 and the regulations  thereunder,  which are  incorporated  herein by
this reference. The term Maximum Permissible Amount means the lesser of:

     (a)  25% of the  Section  415  Compensation  of  that  Participant  for the
Limitation Year, or

     (b) $30,000 or, if greater,  25% of the dollar  limitation  in effect under
Section 415(b)(1)(A) of the Code for the Limitation Year.


         PriceCostco 401(k) Plan for California Union Employees   Page 19





In the  event  that  any  Participant  is a  participant  in any  other  defined
contribution  plan  maintained  by the  Employer,  the  total  amount  of Annual
Additions to such  Participant's  accounts  under all such defined  contribution
plans shall not exceed the  limitations  set forth in this  Paragraph.  Each new
adjusted  dollar  limitation  shall be effective for the Plan Year ending during
the  calendar  year  for  which  the new  adjusted  dollar  limitation  is first
effective.  The limitation of subsection (b) shall not apply to any contribution
for medical  benefits (within the meaning of Sections 401(h) or 419(f)(2) of the
Code), which is otherwise treated as an Annual Addition under Sections 415(l)(1)
or 419(d)(2) of the Code.

5.4        LIMITATION FOR MULTIPLE PLANS

If the  Employer  maintains  one or more  defined  benefit  plans (as defined in
Section 414(j) of the Code), or if the Employer maintains a welfare benefit fund
(as  defined in Section  419(e) of the Code) in  addition  to this Plan (and any
other defined  contribution plans), the contributions made under this Plan shall
not exceed the  limitations  contained in this Section.  The  limitation of this
Section is that the sum of the "defined  benefit plan fraction" and the "defined
contribution plan fraction" for any Plan Year may not exceed 1.0.

The "defined benefit plan fraction" is a fraction, the numerator of which is the
sum of the projected annual benefit of the Participant under all defined benefit
plans  (whether  or  not  terminated)   maintained  by  the  Employer,  and  the
denominator  of  which  is the  lesser  of (i)  125%  of the  dollar  limitation
determined for the Limitation Year under Sections 415(b) and 415(d) of the Code,
or (ii) 140% of the highest  average  compensation,  including  any  adjustments
under Section 415(b) of the Code.

The "defined  contribution plan fraction" is a fraction,  the numerator of which
is the sum of the Annual Additions to the  Participant's  employer  contribution
account or employee  contribution  account under all defined  contribution plans
(whether or not  terminated)  maintained by the Employer for the current and all
prior Limitation Years, and the denominator of which is the sum of the lesser of
the following amounts determined for such Plan Year and for each prior Plan Year
of Service with the Employer: (i) 125% of the dollar limitation determined under
Sections  415(b) and 415(d) of the Code in effect under Section  415(c)(1)(A) of
the Code for such Plan Year (determined  without regard to Section  415(c)(6) of
the Code), or (ii) 35% of the  Participant's  Section 415  Compensation for such
Plan Year. If the  Participant  was a participant as of the end of the first day
of the first  Limitation  Year beginning after December 31, 1986, in one or more
defined contribution plans maintained by the Employer which were in existence on
May 6,  1986,  the  numerator  of the  defined  contribution  fraction  shall be
adjusted if the sum of the defined contribution fraction and the defined benefit
fraction  would  otherwise  exceed 1.0 under the terms of this  Plan.  Under the
adjustment,  an  amount  equal to the  product  of the  excess of the sum of the
fractions  over 1.0 times the  denominator of this fraction shall be permanently
subtracted  from  the  numerator  of this  fraction.  The  adjustment  shall  be
calculated  using the  fractions  as they would be computed as of the end of the
last Limitation Year commencing  prior to January 1, 1987, and  disregarding any
changes in the terms and  conditions  of Plan made after May 6, 1986,  but using
the Section 415 limitation applicable to the first Limitation Year commencing on
or after January 1, 1987. The Annual Addition for any Limitation Year commencing
before January 1, 1987, shall not be recomputed to treat all

         PriceCostco 401(k) Plan for California Union Employees   Page 20





employee  contributions  as Annual  Additions.  If a Participant in this Plan is
also a participant  in a defined  benefit plan  maintained by the Employer,  the
limitations of this Section shall be effected by favoring this Plan and then the
defined benefit plan.

5.5        ADJUSTMENTS FOR EXCESS ANNUAL ADDITIONS

If, as a result of a reasonable error in estimating a Participant's  Section 415
Compensation or other facts and circumstances to which Regulation  1.415-6(b)(6)
shall be applicable, the Annual Addition under this Plan would cause the maximum
Annual  Addition to be exceeded for any  Participant,  the  Administrator  shall
proceed as follows.  If the Annual Addition  allocated to the Participant  under
other  defined  contribution  plans and welfare  benefit  funds is less than the
maximum  allowable,  and the contributions  that otherwise would be allocated to
the  Participant's  Account under this Plan would cause the Annual  Addition for
the Plan Year to exceed the  limitations,  the amount  allocated under this Plan
shall be reduced so that the Annual  Additions  under all such plans and welfare
benefit funds for the year will equal the maximum allowable Annual Addition.  If
the Annual Addition  allocated under such other defined  contribution  plans and
welfare  benefit funds in the aggregate are equal to or greater than the maximum
allowable  addition to the  Participant's  account for the year in question,  no
amount shall be contributed or allocated  under this Plan for that Plan Year. If
a Participant's  Annual Addition under this Plan and such other plans results in
an excess Annual Addition for the Plan Year, the excess amount shall be disposed
of as follows:

     (a) First, any nondeductible voluntary contributions by a Participant shall
be returned to the  Participant  to the extent that the return  would reduce the
excess Annual Addition;

     (b) Second,  if there  remains an excess  Annual  Addition  resulting  from
Employer  contributions  or  forfeitures,  such excess Annual  Addition shall be
deducted first from the Matching  Contribution  Account,  to the extent thereof,
and then, if necessary,  from the Salary Deferral Account. Such amounts shall be
applied to reduce future Employer contributions for such Participant in the next
Plan Year and each Plan Year thereafter until disposed of.

     (c)  Third,  if there  remains an excess  Annual  Addition  resulting  from
Employer contributions or forfeitures, and the Participant is not covered by the
Plan at the end of the Plan  Year,  the  excess  Annual  Addition  shall be held
unallocated  in a suspense  account.  The suspense  account  shall be applied to
reduce future Employer  contributions for all remaining Participants in the next
Plan Year and each Plan Year thereafter until disposed of. If a suspense account
is in existence at any time during the Plan Year pursuant to this section,  such
suspense  account  shall  not  participate  in the  allocation  of  the  trust's
investment gains and losses.

     (d)  Fourth,  if upon  termination  of the Plan  there  remain  unallocated
contributions  or  forfeitures,  such  remaining  balance  may be  repaid to the
Employer upon termination of the Plan.

For  purposes  of  this  section,  "excess  amount"  for any  Participant  for a
Limitation  Year means the excess,  if any, of the Annual  Addition  which would
otherwise be credited to the  Participant's  account under the terms of the Plan
without  regard to the  limitations  of Code Section 415 over the maximum Annual
Addition allowed.

                            PARTICIPANT CONTRIBUTIONS

6.1        PARTICIPANT ROLLOVER AND TRANSFER CONTRIBUTIONS

Any Participant,  with the Plan Administrator's written consent and after filing
with the Trustee the form prescribed by the Plan  Administrator,  may contribute
cash or other  property to the Trust other than as a voluntary  contribution  if
the contribution is a qualified  "rollover  contribution" which the Code permits
an Employee to transfer either directly or indirectly from one qualified plan to
another  qualified  plan  ("Rollover  Contribution"),  as long  as the  Rollover
Contribution will not require any changes to the operation and administration of
this Plan or the  provision  of any form of  distribution  other than a lump sum
distribution.  Before accepting a Rollover Contribution, the Trustee may require
an Employee to furnish  satisfactory  evidence that the proposed  transfer is in
fact a qualified Rollover  Contribution.  In addition, if the Plan Administrator
determines to accept accounts  transferred from other qualified plans, there may
be transferred to the Trustee all or any of the assets held for the benefit of a
Participant in any other plan that satisfies the  applicable  requirements  as a
qualified  plan  under  Sections  401(a)  and  403(a)  of  the  Code  ("Transfer
Contribution").  If a contribution is made to the Trust under this section,  the
Trustee  shall hold the  amount  contributed  in a  segregated  Account  for the
Participant's  sole  benefit.  The  interest  of each  Participant  in all  such
Employee  Contribution  Accounts shall be 100% vested and  Nonforfeitable at all
times.

6.2        WITHDRAWAL OF ROLLOVER AND TRANSFER CONTRIBUTIONS

A Participant,  upon 30 days' prior written  notice to the Trustee,  may request
withdrawal  of all or any part of the  Participant's  Rollover  Contribution  or
Transfer  Contribution.  The Trustee  shall comply with a request to withdraw as
soon as  reasonable  and  practicable  given  the time  required  to  convert  a
sufficient portion of a Participant's  Employee Contribution Account to cash and
the availability of an accounting as of the applicable Valuation Date.

                                    ARTICLE 7
                             INVESTMENT OF ACCOUNTS

7.1        INVESTMENT OF ACCOUNTS

A Participant  shall elect in which Investment Fund or Funds his or her Accounts
shall be invested in accordance with this section.

     (a) Investment of Account Balance and Future Contributions. A Participant's
Account balance and a Participant's  future  contributions  shall be invested in
the Investment Fund or Funds elected by the Participant,  as the Participant may
direct from time to time.  Such elections shall be subject to the limitations in
amount or increment  and to such other  requirements  as the Plan  Administrator
from  time  to  time  shall   announce.   Investment   elections   may  be  made
telephonically or by such other method as the Plan Administrator shall determine
from time to time.


         PriceCostco 401(k) Plan for California Union Employees   Page 22





     (b) Direction of Investment by Beneficiary of Participant.  After the death
of a Participant,  the Participant's  Beneficiary  entitled to a distribution of
benefits  under the Plan  shall be  entitled  to make all  elections  under this
section as if such Beneficiary were the Participant.

7.2        OPTIONAL PASS-THROUGH VOTING OF NON-EMPLOYER STOCK

The Plan  Administrator  may  direct the  Trustee,  in all cases or from time to
time, to allow  Participants to direct the Trustee as to the manner in which the
securities,  other that Employer Stock,  allocated to each Participant's Account
shall be voted or how the Trustee  should  respond to a tender  offer or similar
ownership  right. In such event, the Trustee shall deliver to each Participant a
copy of any proxy  solicitation  materials,  tender offer, or other  information
given to  shareholders  of the  securities,  together  with a form by which  the
Participant  may  instruct  the  Trustee  how to vote or  whether  to tender the
securities.  The Trustee shall vote such securities  through proxy in accordance
with  the  instructions  received  from  the  Participant  entitled  to vote the
securities  and shall tender or exercise  other  ownership  rights in accordance
with the instructions of the Participant. The Trustee shall not vote, tender, or
otherwise   exercise   ownership  rights  for  any  such  securities  for  which
instructions are not received from the Participant.

7.3        PASS-THROUGH VOTING OF EMPLOYER STOCK

     (a)  Information  and  Procedures.  Participants  who have  investments  in
Employer  Stock shall be  provided  with the same  information  as that which is
provided to other shareholders, including all proxies, and the Participant shall
have the right to direct the Trustee as to the voting, tender, and other similar
rights of the Employer Stock allocated to the Participant's Account. Information
regarding  a  Participant's  exercise  of such  rights  shall be  maintained  in
accordance  with  procedures  designed to safeguard the  confidentiality  of the
purchase,  holding,  or sale of Employer  Securities and the exercise of voting,
tender,  and other ownership  rights,  except to the extent  necessary to comply
with  federal  or state  laws  that  are not  preempted  by  ERISA  (such as the
reporting requirement for "insiders" under Section 16 of the Securities Exchange
Act of 1934).

     (b)  Appointment  of  Special  Fiduciaries.  The Plan  Administrator  shall
designate a company fiduciary to be responsible for ensuring that the procedures
requiring the  safeguarding of confidential  information as to the ownership and
exercise of ownership rights are adequate and utilized. In addition, the company
fiduciary shall appoint an independent fiduciary (who may not be affiliated with
the Employer or any  Affiliated  Company) to carry out any  activities  that the
company fiduciary determines involve a potential for undue employer influence on
Participants  with  regard to the direct or  indirect  exercise  of  shareholder
rights.  Examples of activities  that may have the potential for undue influence
are: tender offers,  exchange offers, and contested board elections. At the time
of the adoption of this instrument,  the Plan  Administrator  has designated the
individual  acting as Executive  Vice President and Chief  Financial  Officer of
Price/Costco,  Inc.,  as the  company  fiduciary  and has  granted  the  company
fiduciary the authority to delegate some or all of such fiduciary  duties to the
individual  acting as Senior Vice President of Human Resources of  Price/Costco,
Inc.


         PriceCostco 401(k) Plan for California Union Employees   Page 23





     (c) Voting of Employer  Stock.  A Participant  may direct the Trustee as to
the manner in which Employer Stock allocated to the Participant's  Account shall
be voted. Before each meeting of the shareholders,  the company fiduciary or the
independent  fiduciary  shall have  delivered to each  Participant a copy of any
proxy  solicitation  materials together with a form by which the Participant may
instruct  the Trustee how to vote the  Employer  Stock.  The Trustee  shall vote
Employer Stock through proxy in accordance with  instructions  received from the
Participant  entitled to vote such  Employer  Stock.  The Trustee shall not vote
Employer  Stock  for  which  voting  instructions  are  not  received  from  the
Participant entitled to vote such Employer Stock. The Trustee, the Employer, the
company fiduciary,  and the independent  fiduciary shall not express any opinion
or recommendation to any Participant concerning the voting of Employer Stock.

     (d) Tender  Offers.  In the event of a tender  offer for shares of Employer
Stock,  the  Trustee  shall  sell,  convey or  transfer  Employer  Stock only in
accordance  with the written  instructions of the  Participant.  The independent
fiduciary  appointed  by the  company  fiduciary  shall have  delivered  to each
Participant all information provided to other shareholders, including (a) a copy
of the  description  of the terms and  conditions of the tender offer filed with
the Securities and Exchange  Commission on Schedule 14D-1,  (b) if requested , a
copy of the statement from management setting forth its position with respect to
the Tender Offer filed with the Securities  and Exchange  Commission on Schedule
14D-9,  (c) an  instruction  form to be used by any  Participant  who  wishes to
instruct  the Trustee to tender  Employer  Stock in response to the tender offer
which  states that  Employer  Stock  allocated  to the  Participant  will not be
tendered if no  instruction  form is  returned  to the Trustee by the  indicated
deadline,  and (d)  such  other  materials  or  information  as the  independent
fiduciary may deem necessary or appropriate.  The Trustee shall sell, convey, or
transfer  shares of Employer  Stock pursuant to the terms of the tender offer as
directed  by the  Participants  on  the  instruction  forms.  The  Trustee,  the
Employer, the company fiduciary, and the independent fiduciary shall not express
any opinion or recommendation to any Participant concerning the tender offer.

                             VESTING AND FORFEITURES

8.1        FULL VESTING

The interest of each  Participant in that  Participant's  Matching Account shall
become fully vested and Nonforfeitable upon the first to occur of any one of the
following events while the Participant is employed by the Employer:

     (a) Upon the attainment of Normal Retirement Age;

     (b) Upon the death or onset of Total Disability of the Participant;

     (c) Upon the  attainment  of 100%  vesting  under the Vesting  Schedule set
forth in this Article;

     (d) Upon the complete termination of the Plan; and

         PriceCostco 401(k) Plan for California Union Employees   Page 24






     (e) With respect to affected Participants,  upon the partial termination of
the Plan.

Any of the  foregoing  events  that occur  after a  Participant  has  terminated
employment  with the Employer shall not result in accelerated  vesting,  and the
vested  percentage of a terminated  Participant  shall be  determined  under the
vesting  schedule  set out  below.  A  Participant's  Salary  Deferral  Account,
Employer Qualified Non-Elective  Contribution Account, and Employee Contribution
Account shall be 100% vested and Nonforfeitable at all times.

8.2        NORMAL VESTING SCHEDULE

In the  event  that the  employment  of a  Participant  with  the  Employer
terminates and none of the events resulting in full vesting under Section 8.1 or
alternative  vesting under Section 8.3 have occurred,  such Participant shall be
vested with a percentage  portion of that  Participant's  Matching  Contribution
Account in accordance with the following Vesting Schedule:

                 Less than 2                                         0%

- ----------------------------------------------------------------------------------------------
              4 but less than 5                                     50%
- ----------------------------------------------------------------------------------------------
                  5 or more                                         100%
- ----------------------------------------------------------------------------------------------



8.3        ALTERNATIVE VESTING SCHEDULE FOR MISCONDUCT

Notwithstanding the foregoing, if a Participant is discharged or resigns and the
Plan  Administrator  determines  that  such  Participant  committed  an  act  of
dishonesty,  disclosed confidential  information,  or engaged in misconduct that
resulted in or might result in material  loss or detriment to the Employer or an
Affiliated  Company,  such Participant shall be vested with a percentage portion
of that  Participant's  Matching  Contribution  Account in  accordance  with the
following Vesting Schedule:



- ----------------------------------------------------------------------------------------------
              Years of Service                                 Percent Vested
- ----------------------------------------------------------------------------------------------
                                                                 
                 Less than 5                                         0%
- ----------------------------------------------------------------------------------------------
                  5 or more                                         100%
- ----------------------------------------------------------------------------------------------



This  alternative  vesting  schedule shall apply only if the Plan  Administrator
makes a  specific  determination  that  the  Participant  engaged  in one of the
specific acts  described  above.  If no such  determination  is made by the Plan
Administrator,  then the  normal  vesting  schedule  set forth in the  foregoing
section shall apply.


         PriceCostco 401(k) Plan for California Union Employees   Page 25





8.4        INCLUDED YEARS OF SERVICE - VESTING

For purposes of determining Years of Service under this Article,  the Plan shall
take into account all Years of Service an Employee  completes  with the Employer
or any Affiliated Company, including Years of Service as an Ineligible Employee.

8.5        FORFEITURES

The Plan Administrator shall administer Forfeitures by forfeiting the non-vested
portion  of a  terminated  Participant's  Employer  Contribution  Account on the
earlier  of (a) the date of  distribution  of the  Participant's  Nonforfeitable
Account balance,  or (b) the date the Participant has five consecutive Breaks in
Service.  For  purposes  of this  section,  if the  value  of the  Participant's
Nonforfeitable  Account balance is zero, the Participant shall be deemed to have
received a distribution of such Nonforfeitable Account balance as of the date of
the Participant's  termination of employment with the Employer. Such Forfeitures
shall be used to pay administrative  expenses of the Plan and to reduce Employer
Contributions to the Plan.

8.6        RESTORATION OF FORFEITURES

If a terminated Participant who has forfeited some portion of his or her account
is  subsequently  reemployed  by the Employer  prior to the  expiration  of five
consecutive  Breaks  in  Service,  the  amount  forfeited  (without  benefit  of
investment  gains or losses) shall be restored to the account if the Participant
repays to the Trust Fund the full dollar  amount  distributed  on account of the
termination  within five years of the reemployment  date. Any such amounts shall
be restored to the account of the  reemployed  Participant as of the last day of
the Plan Year in which the repayment  was made.  The  restoration  shall be made
from any forfeitures  available  before such forfeitures are allocated among the
accounts of other  Participants.  If no forfeitures are available,  the Employer
shall make a special  contribution for this purpose.  Within 30 days of rehiring
any former  Participant  who had forfeited a portion of his or her account,  the
Administrator  shall notify the  Participant of any right the Participant has to
make repayment of the account and of the effect of such repayment.

                                    ARTICLE 9
                            DISTRIBUTION OF BENEFITS

9.1        DISTRIBUTION AFTER AGE 59 1/2

A  Participant  may  apply  for a  distribution  of  all  or a  portion  of  the
Participant's  Nonforfeitable Account balance at any time after attaining age 59
1/2.

9.2        DISTRIBUTION UPON SEPARATION FROM SERVICE

The Participant's benefit upon separation from Service with the Employer for any
reason shall be the total of the Participant's  Nonforfeitable  Account balances
as  of  the  semi-monthly   date  that  termination   distributions  are  posted
immediately following the date on which the Participant's  completed application
for distribution of benefits and consent to distribution is received by the

     PriceCostco 401(k) Plan for California Union Employees   Page 26




Plan  Administrator.  If the  value of a  Participant's  Nonforfeitable  Account
balance (derived from combined Employer and Employee  contributions,  other than
any  accumulated  deductible  employee  contributions,  if the Plan is hereafter
amended to allow such deductible  employee  contributions)  exceeds, or has ever
exceeded,  $3,500,  distribution  may not be made before Normal  Retirement  Age
without  the consent of the  Participant.  If the  Participant's  Nonforfeitable
Account  balance  (derived  from combined  Employer and Employee  contributions,
other than any accumulated deductible Employee  contributions)has never exceeded
$3,500,  no consent to a  distribution  of the  Participant's  benefit  shall be
required,  and the Participant  shall be deemed to have submitted an application
for  distribution  of benefits as of the date on which he or she separated  from
Service. Distribution of a Participant's Nonforfeitable Account balance shall be
made within a reasonable  period of time after the  termination  distribution is
posted.

9.3        FORM OF  DISTRIBUTION

The  normal  form  of  benefit  shall  be  a  single-sum   distribution  of  the
Participant's  Nonforfeitable  Account  balance,  which  shall  be  made  to the
Participant, if living, or if not, to the Participant's surviving Spouse, but if
there  is no  surviving  Spouse  or if the  Spouse  has  consented  in a  manner
conforming to Section 12.1, then to the  Participant's  designated  Beneficiary.
The  distribution  shall be made in cash, or in property,  or partly in each, at
the  discretion  of the Trustee,  at its fair market value as  determined by the
Trustee. There shall be no installment or annuity forms of distribution.

9.4        LATEST DATE FOR COMMENCEMENT OF BENEFITS

Under the Act, unless a Participant elects otherwise,  in writing,  distribution
of the Participant's vested Account shall begin no later than the 60th day after
the latest of the following:

     (a) The close of the Plan Year in which the  Participant  attains age 65 or
Normal Retirement Age, if earlier;

     (b) The close of the Plan Year in which occurs the 10th  anniversary of the
year in which the Participant commenced participation in the Plan; or

     (c) The close of the Plan Year in which the Participant  terminates Service
with the Employer.

Notwithstanding  the  foregoing,  the failure of a  Participant  to consent to a
distribution   while  the   Participant's   account   balance   is   immediately
distributable  shall  be  deemed  to be an  election  to defer  commencement  of
distribution of any benefit sufficient to satisfy this section.

9.5        REQUIRED DISTRIBUTION AT AGE 70 1/2

Notwithstanding  any provisions of this Plan to the contrary,  distribution of a
Participant's  Account shall commence no later than April 1 of the calendar year
following the calendar year in which the Participant  attains the age of 70 1/2,
even if the Participant has not yet retired.  The amount of the  distribution to
be made shall be determined in accordance with Internal Revenue

         PriceCostco 401(k) Plan for California Union Employees   Page 27





Code Section 401(a)(9), and the regulations thereunder. Under those regulations,
the amount of the  distribution  shall be the  greater of the amount  determined
under  Proposed  Regulation  Section  1.401(a)(9)-1  or the  minimum  incidental
benefit requirement of Proposed Regulation Section 1.401(a)(9)-2. In calculating
the amount of the  minimum  distributions  required,  life  expectancies  may be
recalculated annually if the Beneficiary is the Participant's Spouse.

9.6        DEATH DISTRIBUTION PROVISIONS

If the Participant dies before distribution of the Participant's entire interest
has been made,  distribution of the  Participant's  remaining  interest shall be
made  to  the   Participant's   Beneficiary   in  a   single   sum  as  soon  as
administratively  feasible,  and  in no  event  later  than  December  31 of the
calendar year  containing  the fifth  anniversary  of the  Participant's  death.
However,  if the Participant's  Beneficiary is the Participant's  Spouse, and if
the Participant's Account balance at the time of the Participant's death exceeds
$3500, the Spouse may elect to defer distribution until a time designated by the
Spouse  but no  later  than  December  31 of the  calendar  year  in  which  the
Participant would have attained age 70 1/2.

9.7        DISTRIBUTION UNDER QUALIFIED DOMESTIC RELATIONS ORDER

Distribution if all or a portion of a Participant's Nonforfeitable Accounts will
be made according to the terms of a "qualified  domestic relations order" to the
child, spouse, or former spouse of a Participant, even though the Participant is
not otherwise  eligible for a distribution  under the Plan. A qualified domestic
relations order is a domestic  relations order,  judgment,  or decree (including
the  approval  of a  property  settlement  agreement)  that (a)  relates  to the
provision of child  support,  alimony,  or property  rights to a spouse,  former
spouse,  child,  or other dependent of a Participant and (b) is made pursuant to
the domestic  relations law of any state;  provided that the Plan  Administrator
determines  that such order meets the  requirements  of Code Section 414 (p) and
related regulations.

9.8        HARDSHIP WITHDRAWALS

A  Participant  shall be  eligible to make a hardship  withdrawal  only from the
Participant's  Salary  Deferral  Account  in  the  event  of  certain  financial
hardships,  if the  requirements  of this  section are met. The amount of such a
distribution  shall  not  exceed  the  amount  of the  financial  need,  and the
distribution  may be  made  only  from  actual  Salary  Deferral  Contributions,
excluding any earnings.  No amounts may be withdrawn  unless the  Participant is
able to demonstrate financial hardship.  For purposes of this section,  hardship
is defined as  certain  specified  immediate  and heavy  financial  needs of the
Participant where such Participant lacks other available resources.

The financial  need must satisfy both the "hardship"  requirements  of Treasury
Regulation  1.401(k)-1(d)(2)(iii)  and any additional  requirements  that may be
adopted by the Plan Administrator on a uniform and  nondiscriminatory  basis. At
present, the Plan Administrator will authorize hardship withdrawals only for the
following financial needs:

     (a)  Unreimbursable   expenses  incurred  or  necessary  for  medical  care
(described in Code Section 213(d))of the Participant,  the Participant's Spouse,
or the Participant's dependents (as defined in Code Section 152);

         PriceCostco 401(k) Plan for California Union Employees   Page 28






     (b) Costs directly related to the purchase of a principal residence for the
Participant (excluding payments on a note secured by a mortgage or deed of trust
on such principal residence);

     (c) Payment of tuition and related  educational fees for the next 12 months
of post-secondary  education for the Participant,  the Participant's  Spouse, or
the Participant's minor children or dependents (as defined in Code Section 152);

     (d)  Payments  to prevent  the  eviction  of the  Participant  from (or the
foreclosure  on the  mortgage  or deed of trust  secured  by) the  Participant's
principal residence; or

     (e) Any other event specified by the  Commissioner of Internal Revenue as a
"safe harbor" constituting an immediate and heavy financial hardship.

The Participant  must supply written  evidence of the financial need,  including
any supporting documentation requested by the Plan Administrator. A distribution
will be considered as necessary to satisfy the need only if all of the following
conditions are satisfied:

     (f) The  Participant  has no other  resources  available  to meet the need,
including the resources of the Participant's  Spouse and minor children that are
reasonably available to the Participant;

     (g) The  Participant  has obtained all  distributions,  other than hardship
distributions,  and all  non-taxable  loans  under all plans  maintained  by the
Employer;

     (h) The  Participant  declares,  under  penalty of  perjury,  that the need
cannot be relieved by any of the following:

           (1) Reimbursement or compensation by insurance or otherwise;

           (2) Reasonable liquidation of the Participant's assets (or the assets
of the  Spouse  or  minor  children  of the  Participant)  to  the  extent  such
liquidation will not itself increase the amount of the need;

           (3) Suspending all of the Participant's contributions to this Plan
and to any other plan (and the Spouse's contributions to any plan);

           (4) Applying for distributions or loans from any other plans in
which the Participant or the Participant's Spouse participate; or

           (5)  Borrowing from commercial sources on reasonable commercial
terms in an amount sufficient to satisfy the need; and

     (i) The  distribution  is not in excess of the amount of the  immediate and
heavy financial need (including amounts necessary to pay any federal,  state, or
local  income  taxes or  penalties  reasonably  anticipated  to result  from the
hardship distribution).

         PriceCostco 401(k) Plan for California Union Employees   Page 29






In  the  event  that  a  Participant  receives  a  hardship  distribution,   the
Participant  may make no further Salary  Deferral  Contributions,  (or any other
employee  contributions  that may be allowed by the Plan in the  future) to this
Plan or to any other plan  maintained  by the Employer for a period of 12 months
from the date the hardship  distribution is posted to the Participant's  Account
by the Trustee.  For this purpose the phrase "any other plan  maintained  by the
Employer"   includes  all   qualified  and   non-qualified   plans  of  deferred
compensation  maintained by the Employer,  including  the  PriceCostco  Deferred
Compensation  Plan  for  Employees  of  Costco  Wholesale  Corporation  and  the
PriceCostco  Deferred  Compensation Plan for Employees of The Price Company. The
phrase  also  includes  Participant  contributions  to any stock  option,  stock
purchase,  or similar plans and any cash or deferred arrangement that is part of
a cafeteria  plan within the meaning of Code  Section 125.  However,  the phrase
does not include  contributions to health or welfare benefit plans,  such as the
PriceCostco  FlexPlan,  including  health and  welfare  plans that are part of a
cafeteria  plan  within  the  meaning  of  Code  Section  125.  In  addition,  a
Participant  who receives a hardship  distribution  may not make Salary Deferral
Contributions  to this  Plan  for the  Participant's  taxable  year  immediately
following  the  taxable  year of the  hardship  distribution  in  excess  of the
applicable limit under Section 401(g) of the Code for such taxable year, reduced
by the amount of the Participant's Salary Deferral Contributions for the taxable
year of the hardship distribution.

9.9        DIRECT ROLLOVER FOR ELIGIBLE DISTRIBUTIONS

Notwithstanding  any other provision of the Plan to the contrary,  a distributee
may elect,  at the time and in the manner  prescribed by the  Administrator,  to
have any  portion of an  eligible  rollover  distribution  paid  directly  to an
eligible retirement plan specified by the distributee in a direct rollover.

The following definitions shall apply to the foregoing:

     (a) Eligible rollover  distribution:  An eligible rollover  distribution is
any  distribution  of all or any  portion  of the  balance  to the credit of the
distributee, except that an eligible rollover distribution does not include: any
distribution  that is one of a series of substantially  equal periodic  payments
(not less  frequently  than annually) made for the life (or life  expectancy) of
the  distributee  or  the  joint  lives  (or  joint  life  expectancies)  of the
distributee and the  distributee's  designated  beneficiary,  or for a specified
period of ten years or more; any distribution to the extent such distribution is
required  under  Section   401(a)(9)  of  the  Code;  and  the  portion  of  any
distribution that is not includible in gross income  (determined  without regard
to the  exclusion  for net  unrealized  appreciation  with  respect to  employer
securities).

     (b) Eligible  retirement plan: An eligible retirement plan is an individual
retirement  account described in Code Section 408(a),  an individual  retirement
annuity  described in Code  Section  408(b),  an annuity plan  described in Code
Section 403(a),  or a qualified  trust  described in Code Section  401(a),  that
accepts the distributee's eligible rollover  distribution.  However, in the case
of an  eligible  rollover  distribution  to the  surviving  Spouse,  an eligible
retirement  plan is an individual  retirement  account or individual  retirement
annuity.


         PriceCostco 401(k) Plan for California Union Employees   Page 30





     (c) Distributee:  A distributee includes an Employee or former Employee. In
addition,   the  Employee's  or  former  Employee's  surviving  Spouse  and  the
Employee's  or former  Employee's  Spouse or former  spouse who is the alternate
payee under a qualified  domestic  relations  order,  as defined in Code Section
414(p),  are  distributees  with regard to the  interest of the Spouse or former
spouse.

     (d)  Direct  rollover:  A direct  rollover  is a payment by the plan to the
eligible retirement plan specified by the distributee.

                       RIGHTS AND REMEDIES OF PARTICIPANTS

10.1       ANNUAL STATEMENTS

As soon as practicable  after the Anniversary  Date of each Plan Year but within

No  Participant,  except a member  of the  Committee,  shall  have the  right to
inspect the records reflecting the Account of any other Participant.

10.2       ASSIGNMENT OR ALIENATION

Except with respect to federal income tax withholding, neither a Participant nor
a Beneficiary  shall assign or alienate any benefit provided under the Plan, and
the Trustee shall not recognize any such assignment or alienation. The preceding
sentence shall also apply to the creation, assignment, or recognition of a right
to any benefit  payable  with  respect to a  Participant  pursuant to a domestic
relations  order,  unless such order is  determined  to be a qualified  domestic
relations order, as defined in Section 414(p) of the Code and Section 9.7 of the
Plan.


         PriceCostco 401(k) Plan for California Union Employees   Page 31





10.3       NOTICE OF CHANGE IN TERMS

The Plan Administrator, within the time prescribed by the Act and the applicable
regulations,   shall  furnish  all  Participants  and  Beneficiaries  a  summary
description of any material amendment to the Plan or notice of discontinuance of
the Plan and all other  information  required by the Act to be furnished without
charge.

10.4       INFORMATION AVAILABLE

Any  Participant in the Plan and any  Beneficiary of a deceased  Participant may
examine copies of the "summary plan  description," the latest annual report, any
bargaining  agreement,  this Plan,  the  Trust,  and any  contract  or any other
instrument  under  which  the  Plan was  established  or is  operated.  The Plan
Administrator will maintain all of the items listed in the Plan  Administrator's
office, or in such other place or places as the Plan Administrator may designate
from time to time in order to comply with the regulations  issued under the Act,
for examination during reasonable  business hours. Upon the written request of a
Participant or Beneficiary,  the Plan Administrator shall within 30 days furnish
a copy of any item listed in this  section.  The Plan  Administrator  may make a
reasonable charge to the requesting person for the copy so furnished.

10.5       DENIAL OF BENEFITS

The  Plan  Administrator  shall  provide  adequate  notice  in  writing  to  any
Participant and to any Beneficiary of a deceased Participant  ("Claimant") whose
claim for  benefits  under the Plan has been  denied.  The Plan  Administrator's
notice to the Claimant shall set forth:

     (a) The specific reason for the denial;

     (b) Specific  references  to pertinent  Plan  provisions  on which the Plan
Administrator based its denial;

     (c) A description of any additional material and information needed for the
Claimant  to  perfect  the  claim  and an  explanation  of why the  material  or
information is needed;

     (d) A statement that the Claimant has a right to appeal and that any appeal
the Claimant wishes to make of the adverse  determination  must be in writing to
the Plan Administrator  within 60 days after receipt of the Plan Administrator's
notice of denial of benefits;

     (e) A statement  that the  failure of the  Claimant to appeal the action to
the Plan  Administrator in writing within the 60 day period will render the Plan
Administrator's determination final, binding and conclusive; and

     (f) The name of each  member of the  Committee  and the name and address of
the committee member to whom the Claimant may forward his appeal.

10.6       APPEAL PROCEDURE

         PriceCostco 401(k) Plan for California Union Employees   Page 32






A Claimant  or his or her duly  authorized  representative  may  submit  written
comments and arguments to the Plan  Administrator  in connection  with an appeal
and may review pertinent Plan documents.  The Plan Administrator shall reexamine
all facts  related to the appeal and may  consult  with  counsel  regarding  the
appeal.  The Plan  Administrator  shall  then make a final  determination  as to
whether the denial of benefits is justified  under the  circumstances.  The Plan
Administrator  shall advise the  Claimant of its decision  within 60 days of the
Claimant's written request for review,  unless special  circumstances (such as a
hearing)  would  make  the  rendering  of a  decision  within  the 60 day  limit
impractical. However, in no event shall the Plan Administrator render a decision
respecting  a denial  for a claim for  benefits  later  than 120 days  after its
receipt of a request for review.

10.7       LITIGATION AGAINST THE TRUST

If any legal action filed against the Trustee,  the Plan  Administrator,  or any
member or  members  of the  Committee,  by or on behalf  of any  Participant  or
Beneficiary,  results  adversely to the Participant or to the  Beneficiary,  the
Trustee shall reimburse itself, the Plan Administrator, or any member or members
of the Committee  for all costs and fees  expended by it or them by  surcharging
all costs and fees against the sums payable under the Plan to the Participant or
to the  Beneficiary,  but only to the extent a court of  competent  jurisdiction
specifically authorizes and directs any such surcharges.

10.8       DISTRIBUTION FOR MINOR BENEFICIARY

In the event a distribution is to be made to a minor, then the Administrator may
direct that such  distribution be paid to the legal  guardian,  or if none, to a
parent of such  Beneficiary  or a  responsible  adult with whom the  Beneficiary
maintains his or her residence,  or to the custodian for such Beneficiary  under
the Uniform  Gift to Minors Act or Gift to Minors Act, if such is  permitted  by
the laws of the state in which said Beneficiary  resides.  Such a payment to the
legal guardian, custodian or parent of a minor Beneficiary shall fully discharge
the Trustee, Employer, and Plan from further liability on account thereof.

                                   ARTICLE 11
                       EMPLOYER ADMINISTRATIVE PROVISIONS

11.1       INFORMATION TO PLAN ADMINISTRATOR

11.2       NO LIABILITY

The Employer  assumes no obligation or  responsibility  to any of its Employees,
Participants,  or  Beneficiaries  for any act, or failure to act, on the part of

11.3       INDEMNITY OF TRUSTEE AND COMMITTEE

The Employer  indemnifies  and holds harmless the Trustee and the members of the
Committee,  and each of them,  from and against any and all loss  resulting from
liability to which the Trustee or the members of the  Committee may be subjected
by reason of any act or conduct (except willful  misconduct or gross negligence)
in their  official  capacities  in the  administration  of the Trust or Plan, or
both,  including all expenses  reasonably incurred in their defense, in case the
Employer fails to provide such defense.  The indemnification  provisions of this
section shall not relieve the Trustee or any Committee member from any liability
such may have under the Act for breach of a fiduciary duty.

                                   ARTICLE 12
                      PARTICIPANT ADMINISTRATIVE PROVISIONS

12.1       BENEFICIARY DESIGNATION

Any  Participant  may from time to time  designate,  in  writing,  any person or
persons  contingently or successively,  to whom the Trustee shall distribute the
Participant's  Account balance in the event of the Participant's death. The Plan
Administrator   shall  prescribe  the  form  for  the  written   designation  of
Beneficiary. When the Participant files a form with the Plan Administrator,  the
latest form filed shall revoke all designations  filed prior to that date by the
same Participant.

In the event the  Participant  is  married  and not  legally  separated  and the
Participant  seeks  to  name  a  Beneficiary  other  than  the  Spouse  of  that
Participant,  that  Beneficiary  designation  shall not be effective unless that
designation  contains the written consent of the Spouse of the Participant.  The
writing must  acknowledge  the effect of the consent,  and the  signature of the
Spouse  must be  witnessed  by a notary  public  or,  if  permitted  by the Plan
Administrator,  by a representative of the Plan Administrator.  Such consent may
not be required,  however,  if it is established to the satisfaction of the Plan
Administrator  that the consent of the Participant's  Spouse may not be obtained
because  there is no Spouse,  because the Spouse cannot be located or because of
such other  circumstances  as may be permitted  under  Section  417(a)(2) of the
Code.  The written  consent of a  Participant's  Spouse must state the  specific
beneficiary   (including   any  class  of   beneficiaries   or  any   contingent
beneficiaries)  who will  receive the  benefit and the form of payment  from any
optional  methods  of  payment  available  to the  Participant,  if the  Plan is
hereafter  amended to provide  optional  forms of payment.  In lieu of this, the
Participant's  Spouse may give a general consent,  permitting the Participant to
change the designated  Beneficiary  without requiring any further consent by the
Spouse,  or a limited general consent,  permitting the Participant to change the
Beneficiary  among a  specified  group of  beneficiaries,  without  any  further
consent by the Spouse.  A general  consent or a limited general consent shall be
invalid unless the consent acknowledges that the Spouse has the right to limit

         PriceCostco 401(k) Plan for California Union Employees   Page 34





consent to a specific  Beneficiary or group of Beneficiaries and that the Spouse
voluntarily elects to relinquish such right.

A designation of Beneficiary inconsistent with the preceding paragraph shall not
be  binding  on  the  Plan  Administrator,  and  the  Plan  Administrator  shall
distribute  benefits first to the Participant's  surviving Spouse. A designation
of  Beneficiary  other than the  Spouse  shall be  automatically  revoked on the
marriage or remarriage  (other than a common-law  marriage) of a Participant and
any designation of the Spouse as Beneficiary  shall be automatically  revoked on
any finalized dissolution of marriage of a Participant subsequent to the date of
filing of the designation of the Beneficiary. Except as specifically provided in
Section 414(p) of the Code or any qualified domestic relations order issued with
respect thereto,  nothing  contained in the Retirement Equity Act of 1984 or the
Code shall give the Spouse the power to designate a beneficiary  of the Spouse's
interest in the Plan if the Spouse predeceases the Participant.

12.2       NO BENEFICIARY DESIGNATION

If a Participant  fails to name a Beneficiary,  or if the Beneficiary named by a
Participant  predeceases the Participant or dies before complete distribution of
the Participant's  Account balance, then the Trustee shall pay the Participant's
Account balance in the following order of priority to the following:

     (a) The Participant's surviving Spouse; then

     (b) The Participant's  surviving issue, including adopted persons, in equal
shares, on the principle of representation; then

     (c)  The  Participant's  estate,  provided,   however,  that  if  the  Plan
Administrator   cannot  locate  a  qualified   representative  of  the  deceased
Participant's  estate  or if no such  representative  has been  appointed  by an
appropriate  court,  then the  Participant's  heirs-at-law  as determined in the
reasonable judgment of the Plan Administrator; then

     (d) The Plan.

The Plan Administrator shall direct the Trustee as to the method and to whom the
Trustee shall make payment under this section.

12.3       PERSONAL DATA TO PLAN ADMINISTRATOR

Each Participant and each Beneficiary of a deceased  Participant must furnish to
the Plan Administrator  current  information as to that person's Social Security
number, date of birth, current employment, current compensation, current marital
status, and the names of the members of that person's immediate family including
Spouse,  children,  and parents, and such evidence as is reasonably necessary to
substantiate any of that information.  The provisions of this Plan are effective
for the  benefit of each  Participant  upon the  condition  precedent  that each
Participant will furnish promptly full, true, and complete  evidence,  data, and
information when requested

         PriceCostco 401(k) Plan for California Union Employees   Page 35





by the Plan Administrator.  The Plan Administrator shall advise each Participant
of the effect of any failure to comply with its request for information.

12.4       ADDRESS FOR NOTIFICATION

Each Participant and each Beneficiary of a deceased  Participant shall file with
the Plan  Administrator  from time to time, in writing,  his or her current post
office  address  and any  change  of post  office  address.  Any  communication,
statement,  or notice addressed to a Participant or Beneficiary at the last post
office address filed with the Plan Administrator,  or as shown on the records of
the Employer,  shall bind the Participant,  or Beneficiary,  for all purposes of
this Plan.

12.5       NO RIGHT TO CONTINUED EMPLOYMENT

Nothing  contained  in this Plan,  or with respect to the  establishment  of the
Trust, or in the creation of any Account,  or the payment of any benefit,  shall
give  any  Employee,   Participant,   or  Beneficiary  any  right  to  continued
employment,  any legal or equitable right against the Employer or any officer or
Employee of the Employer, or against the Trustee, or its agents or employees, or
against the Plan  Administrator,  except as expressly  provided by the Plan, the
Trust, the Act, or a separate written agreement.

                                   ARTICLE 13
                     POWERS AND DUTIES OF PLAN ADMINISTRATOR

13.1       COMMITTEE MEMBERS' EXPENSES

The  Employer  may appoint a Committee to  administer  the Plan,  the members of
which may or may not be  Participants  in the Plan. The members of the Committee
who are employees of the Employer or any Affiliated  Company shall serve without

the  Committee and the members of the  Committee,  including the expense for any
bond required under the Act.

13.2       VACANCY

In case of a vacancy in the membership of the Committee,  the remaining  members

         PriceCostco 401(k) Plan for California Union Employees   Page 36





     (a) To determine the eligibility of an Employee to participate in the Plan,

with the performance of its duties;

     (i) To engage the services of an investment manager or managers (as defined
in Section  3(38) of the Act),  each of whom shall have full power and authority
to manage, acquire or dispose (or direct the Trustee with respect to acquisition
or disposition) of any Plan asset under its control;  (j) To make determinations
and  grant  hardship  distributions  (and  plan  loans if the plan is  hereafter

material  modification,  employee notice,  enrollment and distribution form, and
all forms,  schedules,  certifications or other communications with the Internal

regulating the Plan.

If the Plan  Administrator is not the Committee,  the Plan  Administrator  shall
have the powers and duties  listed  above,  with the  exception of the following
powers  which  shall  not be given to such a Plan  Administrator  except  by the
express action of the Employer:  the power to establish,  amend or terminate the
Plan and Trust;  the power to change the Trustee;  and the power to execute Plan
and Trust  documents  without  written  authorization  from the Employer or plan
sponsor.  However,  the Plan  Administrator  may have  such  powers  if the Plan
Administrator  is the Employer or if the Employer  specifically  delegates  such
powers to the Plan Administrator.

         PriceCostco 401(k) Plan for California Union Employees   Page 37






The  Plan  Administrator  shall  have  responsibility  for  compliance  with the
reporting  and  disclosure  rules  applicable  to  this  Plan  under  the Act or
otherwise.  All  determinations  made by the Plan  Administrator with respect to
eligibility  for  benefits  and the  terms  of this  Plan  shall  be  based on a
reasonable   interpretation  of  this  Plan  and  shall  be  made  by  the  Plan
Administrator,  in its sole discretion.  The Plan  Administrator  shall maintain
records of its activities.

13.4       FUNDING POLICY

The Plan Administrator shall review, not less often than annually, all pertinent
Employee  information  and Plan data in order to establish the funding policy of
the Plan and to  determine  the  appropriate  methods of carrying out the Plan's
objectives. The Plan Administrator shall communicate annually to the Trustee and
to any Plan  investment  manager the Plan's  short-term and long-term  financial
needs  so  that  investment   policy  can  be  coordinated  with  the  financial
requirements of the Plan.

13.5       AUTHORIZED REPRESENTATIVE

Unless  the  Employer  gives  directions  to the  contrary,  the  Committee  may
authorize  any one or more of its  members to sign on its  behalf  any  notices,

or other documents.  At the request of the Trustee,  the Committee will evidence
this  authority  by an  instrument  signed by all  members  and  filed  with the
Trustee.

13.6       INTERESTED MEMBER

No member of the  Committee may decide or determine  any matter  concerning  the
distribution,  nature,  or method of settlement of his or her own benefits under
the Plan.

13.7       INDIVIDUAL ACCOUNTS

The Plan  Administrator  shall  maintain,  or direct the Trustee to maintain,  a
separate  Account in the name of each  Participant to reflect the  Participant's
Account balance under the Plan.

13.8       VALUE OF PARTICIPANT'S ACCOUNTS

The  Plan  Administrator  shall  value  the  Participants'  Accounts  as of each
Anniversary  Date to  determine  their  fair  market  value and shall  value the
Participants' Accounts on such other dates as may be necessary.

13.9       ACCOUNT CHARGED

The Plan  Administrator  shall charge all distributions made to a Participant or
to his or her Beneficiary against the Account of that Participant when made.

13.10      UNCLAIMED ACCOUNT PROCEDURE


         PriceCostco 401(k) Plan for California Union Employees   Page 38





Neither the Trustee nor the Plan  Administrator  shall be obliged to search for,
or ascertain  the  whereabouts  of, any  Participant  or  Beneficiary.  The Plan
Administrator,  by  certified  or  registered  mail  addressed to the last known
address of record with the Plan Administrator or the Employer,  shall notify any
Participant, or Beneficiary,  that he or she is entitled to a distribution under
this  Plan.  If the  Participant,  or  Beneficiary,  fails to  claim  his or her
distributive  share or make his or her whereabouts  known in writing to the Plan
Administrator  within six months  from the date of  mailing  of the  notice,  or
before this Plan is terminated or  discontinued,  whichever  should first occur,
the Plan  Administrator  shall direct the Trustee to transfer the  Participant's
entire Account balance (the "Unclaimed Account") into the lowest risk investment
fund provided by the Plan as an investment option at the time in question, or if
no such fund is available into a segregated interest-bearing Account in the name
of the  Participant or  Beneficiary.  The Plan  Administrator  shall request the
Social Security Administration to notify the Participant (or Beneficiary) of the
existence of the  Unclaimed  Account in  accordance  with the  procedures it has
established  for this purpose.  The  Unclaimed  Account shall be entitled to all
income it earns and shall bear all  expenses  or losses it incurs.  In the event
the Unclaimed  Account remains  unclaimed for one year after the end of the Plan
Year  during  which the  notice  was  mailed,  the  Unclaimed  Account  shall be
forfeited.  The  amount  so  forfeited  shall  be  treated  as a  forfeiture  in
accordance with the normal provisions of this Plan.  However, if the Participant
or Beneficiary thereafter makes a claim for benefits prior to termination of the
Plan, the amount  forfeited shall be reinstated  (without  benefit of investment
gains or losses) to the account of the Participant or Beneficiary.  The Employer
may use any available  forfeitures for the purpose of such reinstatement.  If no
forfeitures  are available,  the Employer shall make an additional  contribution
for this purpose.

                                   ARTICLE 14
                    EXCLUSIVE BENEFIT, AMENDMENT, TERMINATION

14.1       EXCLUSIVE BENEFIT

Except as  provided  in Section  3.2,  the  Employer  shall  have no  beneficial
interest in any assets of the Trust, and no part of any asset in the Trust shall
ever revert to or be repaid to the  Employer,  either  directly  or  indirectly.
Until  the  satisfaction  of all  liabilities  to  the  Participants  and  their
Beneficiaries  under the Plan,  no part of the  principal or income of the Trust
Fund,  or any asset of the Trust,  shall be used for, or diverted  to,  purposes
other than the exclusive benefit of the Participants or their Beneficiaries.

14.2       AMENDMENT BY EMPLOYER

The Employer, through action of its board of directors (or other governing board
if it is not governed by a board of directors), shall have the right at any time
to amend this Agreement in any manner it deems necessary or advisable; provided,
however,  no  amendment  shall  authorize or permit any of the Trust Fund (other
than the part which is required to pay taxes and administration  expenses) to be
used for or  diverted to purposes  other than for the  exclusive  benefit of the
Participants  or their  Beneficiaries  or estates;  no amendment  shall cause or
permit  any  portion of the Trust  Fund to revert to or become  property  of the
Employer;  and no amendment which affects the rights, duties or responsibilities
of the Trustee, the Plan

         PriceCostco 401(k) Plan for California Union Employees   Page 39





Administrator,  or the Committee may be made without the written  consent of the
affected  Trustee,  the  Plan  Administrator,  or  the  affected  member  of the
Committee.  The Employer may  delegate the  authority to amend or terminate  the
Plan and Trust to the Committee or other Plan  Administrator  from time to time.
At the  Effective  Date,  the  Employer  has  delegated  this  authority  to the
Committee,  which  shall  act in  accordance  with the  resolution  by which the
Committee was appointed and in accordance with the provisions of Article 13.

14.3       AMENDMENT TO VESTING SCHEDULE

Though the  Employer  reserves  the right to amend the  Vesting  Schedule at any
time, the Employer shall not amend the Vesting  Schedule (and no amendment shall
be effective) unless the amendment provides that the  Nonforfeitable  percentage
of  any  Participant's  Account  balance  derived  from  Employer  contributions
(determined as of the later of the date the Employer  adopts the  amendment,  or
the  date  the  amendment  becomes   effective)  shall  not  be  less  than  the
Nonforfeitable  percentage  of that  Account  balance  computed  under  the Plan
without  regard to the  amendment.  No  amendment  to the Plan shall  decrease a
Participant's  Account  balance or eliminate an optional  form of  distribution.
Notwithstanding the preceding sentence,  a Participant's  Account balance may be
reduced  to the  extent  permitted  under  Section  412(c)(8)  of the  Code.  No
amendment  to the Plan  shall  have the  effect of  decreasing  a  Participant's
Nonforfeitable Account balance determined without regard to such amendment as of
the  later  of the  date  such  amendment  is  adopted  or the  date it  becomes
effective.  If the  Employer  makes  a  permissible  amendment  to  the  Vesting
Schedule,  each  Participant  having at least  three  Years of Service  with the
Employer may elect to have the percentage of his Nonforfeitable  Account balance
computed under the Plan without regard to the amendment.  The  Participant  must
file his election  with the Plan  Administrator  within 60 days of the latest of
(a) the  Employer's  adoption of the  amendment;  (b) the effective  date of the
amendment;   or  (c)  his  receipt  of  a  copy  of  the  amendment.   The  Plan
Administrator,  as  soon  as  practicable,  shall  forward  a true  copy  of any
amendment to the Vesting Schedule to each affected Participant, together with an
explanation of the effect of the amendment,  the appropriate form upon which the
Participant may make an election to remain under the Vesting  Schedule  provided
under the Plan prior to the  amendment,  and notice of the time within which the
Participant must make an election to remain under the prior Vesting Schedule.

14.4       DISCONTINUANCE

The Employer shall have the right,  at any time, to suspend or  discontinue  its
contributions  under the Plan,  and to terminate this Plan and the Trust created
under this  Agreement.  The Plan shall  terminate upon the first to occur of the
following:

     (a) The date terminated by action of the Employer or the Committee;

     (b) The  date  the  Employer  shall  be  judicially  declared  bankrupt  or
insolvent; or

     (c)  The  dissolution,  merger,  consolidation,  or  reorganization  of the
Employer or the sale by the Employer of all or substantially  all of its assets,
unless the successor or purchaser

         PriceCostco 401(k) Plan for California Union Employees   Page 40





makes  provision to continue the Plan, in which event the successor or purchaser
shall substitute itself as the Employer under this Plan.

14.5       FULL VESTING ON TERMINATION

Notwithstanding any other provision of this Plan to the contrary,  upon the date
of either full or partial  termination of the Plan, or, if applicable,  upon the
date of a complete  discontinuance  of  contributions  to the Plan,  an affected
Participant's right to his or her Account balance shall be 100%  Nonforfeitable.
The Plan  Administrator  shall interpret and administer this Paragraph in accord
with the extent  and scope of the  Treasury  Regulations  issued  under  Section
411(d)(3) of the Code.

14.6       MERGER

The Trustee shall not consent to, or be a party to, any merger or  consolidation
with another  plan, or to a transfer of assets or  liabilities  to another plan,
unless immediately after the merger,  consolidation,  or transfer, the surviving
Plan  provides  each  Participant a benefit equal to or greater than the benefit
each Participant would have received had the Plan terminated  immediately before
the merger, consolidation, or transfer.

14.7       TERMINATION

Upon   termination  of  the  Plan,  the  provisions  of  the  Article   entitled
"Distribution of Benefits," shall remain operative, and the Trust shall continue
until the Trustee has  distributed  all of the benefits  under the Plan. On each
Anniversary   Date,  the  Plan   Administrator   shall  credit  any  part  of  a
Participant's Account balance retained in the Trust with its proportionate share
of  the  Trust's  income,  expenses,   gains,  and  losses,  both  realized  and
unrealized.

                                   ARTICLE 15
                               GENERAL PROVISIONS

15.1       EVIDENCE

Anyone  required  to give  evidence  under  the  terms  of the Plan may do so by
certificate,   affidavit,   document,   or  other   information  that  the  Plan
Administrator may consider pertinent,  reliable,  and genuine,  and to have been
signed,  made, or presented by the proper party or parties.  Any action required
of the Employer  shall be by  resolution  of the  Employer,  or by resolution or
action of a person or entity authorized by resolution of the Employer.  Both the
Plan  Administrator  and the  Trustee  shall be fully  protected  in acting  and
relying upon any evidence described in this section.

15.2       NO RESPONSIBILITY FOR EMPLOYER ACTION

The  Trustee  and  the  Plan   Administrator   shall  have  no   obligation   or
responsibility  with respect to (a) any action  required by the Plan to be taken
by the Employer,  any Participant,  or eligible Employee, (b) the failure of any
of the above persons to act or make any payment or

         PriceCostco 401(k) Plan for California Union Employees   Page 41





contribution,  or to otherwise provide any benefit contemplated under this Plan,
or (c)  the  collection  of any  contribution  required  under  the  Plan or the
determination of the correctness of the amount of any Employer contribution.

15.3       RESTRICTIONS OF THE ACT

The  Trustee  and the  Plan  Administrator  and  any  other  person  who has any
fiduciary responsibility with respect to the Plan shall discharge its duties and
responsibilities  with respect to the Plan in accordance  with the standards set
forth in Section 404 (a)(1) of the Act, which provides:

           "Subject  to sections  403(c) and (d),  4042,  and 4044,  a fiduciary
           shall  discharge  his duties  with  respect  to a plan  solely in the
           interest of the participants and beneficiaries and--

           (A)      for the exclusive purpose of:

                    (i)      providing benefits to participants and their
                             beneficiaries; and

                    (ii)     defraying reasonable expenses of administering
                             the plan:

           (B)  with  the  care,  skill,   prudence,  and  diligence  under  the
circumstances  then  prevailing that a prudent man acting in a like capacity and
familiar  with such matters  would use in the conduct of an enterprise of a like
character and with like aims;

           (C)  by diversifying the investments of the plan so as to minimize
the risk of large losses, unless under the circumstances it is clearly prudent
not to do so; and

           (D) in accordance  with the documents and  instruments  governing the
plan  insofar  as  such  documents  and  instruments  are  consistent  with  the
provisions of this title and title IV."

15.4       FIDUCIARIES NOT INSURERS

The Trustee,  the Plan  Administrator,  and the Employer in no way guarantee the
Trust  Fund from loss or  depreciation.  The  Employer  does not  guarantee  the
payment of any money  which may be or become  due to any  person  from the Trust
Fund.  The  liability  of the Plan  Administrator  and the  Trustee  to make any
payment  from  the  Trust  Fund at any  time and all  times  is  limited  to the
then-available assets of the Trust.

15.5       WAIVER OF NOTICE

Any person entitled to notice under the Plan may waive the notice.

successors and assigns, and upon the Trustee, the Plan Administrator,  and their
successors.
