Exhibit 10.2.3

COSTCO WHOLESALE CORPORATION
RESTRICTED STOCK UNIT AWARD AGREEMENT

1.Grant of Stock Units. You are hereby granted Non-Executive Director Stock
Units covering the number of shares of Costco Wholesale Corp. common stock (the
“Shares”) specified in the Grant Detail made available electronically in
connection with the grant (the “Detail”). This grant is subject to the terms and
conditions of this Agreement and of the Costco Wholesale Corporation 2019 Stock
Incentive Plan (the "Plan"), a copy of which can be obtained through the
Financial Planning Department.
2.Vesting Schedule and Delivery of Shares.
(a) The Stock Units are not Shares; they will be converted into Shares when the
Stock Units vest. Generally, your Stock Units will vest into Shares on the
schedule set forth in the Notice and you will receive the Shares within ten
business days of the vest date. Any Stock Units that have not vested under the
Detail or this Agreement shall be forfeited. Fractional shares will be rounded
down to the nearest whole number.
(b) Directors who terminate from service will receive daily vesting of Stock
Units. For each day that has passed since the anniversary of your grant date you
will vest in 1/365th of the Stock Units that were scheduled to vest that grant
year. For example, if you receive a grant on October 22 of 2,400 Stock Units
with a three-year vesting schedule and you terminate on the next April 23 (182
days later), you will vest as to 398 Stock Units (one-third times 2,400 times
[182/365]). You will receive shares within 90 days of termination.
(c) Directors who terminate from service after five or more years of service on
the Board of Directors shall qualify for accelerated vesting on termination.
Should you terminate after five years of service on the Board of Directors, 50%
of the Stock Units that would otherwise be unvested at your termination date
shall vest on termination. Should you terminate after ten years of service on
the Board of Directors, 100% of the Stock Units that would otherwise be unvested
at your termination date shall vest on termination. You will receive shares
within 90 days of termination.
(d) Accelerated vesting also will occur at death. In the event of your death,
you will vest in 100% of the otherwise unvested Stock Units. Shares will be
distributed within 90 days of death.
3.     No Shareholder Rights. Stock Units represent hypothetical shares of
Stock. Until the Stock Units vest, you shall not be entitled to any of the
rights or benefits generally accorded to shareholders. Unless otherwise
determined by the Administrator, delivery of Shares shall be effected by
book-entry credit to a custody account (the "Custody Account") maintained by you
with a Custodian designated by the Company. No delivery of Shares shall be made
unless a Custody Account has been established for you. You shall be the
beneficial owner of any Shares properly credited to the Custody Account. You
shall have no right to any dividend or distribution or vote or other shareholder
rights with respect to such Shares if the record date for such event is prior to
the date the Custody Account is properly credited with such Shares.
4.     Taxes.
(a) For tax reporting and withholding purposes, the value of any Shares issued
shall be determined based on the closing stock price on the date of vesting
regardless of when the Shares are actually credited to a Custody Account. The
Director shall be liable for any and all taxes, including withholding taxes,
interest or penalties arising out of this grant, the vesting of Stock Units
hereunder, or the transfer of Shares or other property in settlement of the
Stock Units. In the event that the Company is required to withhold taxes as a
result of the grant or vesting of Stock Units, the transfer of Shares or other
property in settlement of the Stock Units, or any subsequent sale of Shares
issued in settlement of such Stock Units, the Director shall surrender a
sufficient number of whole Shares as necessary to cover all required withholding
taxes and required social security contributions at the time the restrictions on
the Stock Units lapse, unless alternative procedures for payment are established
prior to the applicable vesting date by the Company. The Company has no
obligation to provide for alternative procedures. To the extent that any
surrender of Shares or payment of cash or alternative procedure for such payment
is insufficient, the Director authorizes the Company and its Affiliates, which
are qualified to deduct tax at source, to deduct all applicable required
withholding taxes and social security contributions from the Director’s
compensation unless the Director has made other arrangements to pay cash for
such excess withholding obligation. The Director agrees to pay the Company any
amounts that cannot be satisfied from other cash compensation, to the extent
permitted by law.

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

(b) Regardless of any action the Company takes with respect to any or all income
tax, social security, payroll tax, payment on account, other tax-related
withholding or information reporting ("Tax-Related Items"), the Director
acknowledges and agrees that the ultimate liability for all Tax-Related Items
legally due by him or her is and remains the Director’s responsibility and that
the Company: (i) make no representations nor undertakings regarding the
treatment of any Tax-Related Items in connection with any aspect of this grant
of Stock Units, including the vesting of Stock Units, subsequent payment of
Shares and/or cash related to such Stock Units or the subsequent sale of any
Shares acquired pursuant to such Stock Units; and (ii) does not commit to
structure the terms or any aspect of this grant of Stock Units to reduce or
eliminate the Director’s liability for Tax-Related Items. The Director shall pay
the Company any amount of Tax-Related Items that the Company may be required to
withhold as a result of the Director’s participation in the Plan or the
Director’s receipt of Stock Units that cannot be satisfied by the means
previously described. The Company may refuse to deliver Shares if the Director
fails to comply with the Director’s obligations in connection with the
Tax-Related Items.
5.     Data Privacy Consent. The Director consents, to the extent applicable law
requires consent, to the collection, use and transfer, in electronic or other
form, of the Director’s personal data by and among, the Company and its
Affiliates for the exclusive purpose of administering the Director’s
participation in the Plan. The Director understands that the Company and its
Affiliates hold certain personal information about the Director, including name,
home address and telephone number, date of birth, social security or insurance
number or other identification number, salary, nationality, job title, any
shares of stock or directorships held in the Company, details of any entitlement
to shares of stock awarded, canceled, purchased, exercised, vested, unvested or
outstanding in the Director’s favor for the purpose of administering the Plan
("Data"). The Director understands that the Data may be transferred to third
parties assisting in the administration of the Plan, that these recipients may
be located in the Director’s country or elsewhere and that the recipient country
may have different data privacy laws and protections than the Director’s
country. The Director may request a list with the names and addresses of any
potential recipients of the Data, request information as to the nature of the
Data provided to other parties, and withdraw in writing the consent contained in
this section, all by contacting the Financial Planning Department, and
understands that refusing or withdrawing consent may affect his ability to
participate in the Plan.
6.     Plan Information. The Director acknowledges that the Director has
received copies of the Plan and the Plan prospectus from the Company and agrees
to receive shareholder information, including copies of any annual report, proxy
statement and periodic report, from the investor relations section of the
Company's website at http://www.costco.com. The Director acknowledges that
copies of the Plan, Plan prospectus, Plan information and shareholder
information are also available upon written or telephonic request to the
Financial Planning Department.
7.     Miscellaneous.
(a) Stock Units shall not be sold, encumbered, pledged or otherwise disposed of,
whether voluntarily or by operation of law. The Company shall not be required to
treat as the owner of Stock Units, and associated benefits hereunder, any
transferee to whom such Stock Units or benefits shall have been so transferred
in violation of this Agreement.
(b) The parties agree to execute such further instruments and to take such
action as may reasonably be necessary to carry out the intent of this Agreement.
(c) Any notice required or permitted hereunder shall be given in writing and
shall be deemed effectively given upon delivery to the Director at the address
then on file with the Company.
(d) The Plan is incorporated herein by reference. The Plan and this Agreement
and the Detail constitute the entire agreement of the parties with respect to
the subject matter hereof and supersede in their entirety all prior undertakings
and agreements of the Company and the Director with respect to the subject
matter hereof, and may not be modified adversely to the Director’s interest
except by means of a writing signed by the Company and the Director. This
Agreement is governed by the laws of the State of Washington. In the event of
any conflict between the terms and provisions of the Plan and this Agreement,
the Plan terms and provisions shall govern (subject to section 7(e)).
Capitalized terms used but not defined in this Agreement have the meanings
assigned to them in the Plan. Certain other important terms governing this
contract are contained in the Plan. If issues of interpretation arise under this
Agreement, the judgment of the Administrator shall be final.
(e) To the extent the Company determines that this Agreement is subject to
section 409A, but does not conform with the requirements thereof, the Company
may at its sole discretion amend or replace the Agreement to cause the Agreement
to comply with section 409A.
