     COSTCO WHOLESALE  CORPORATION,  a Washington corporation (herein called the
"Company",  which term shall refer to such Company until a successor corporation
shall have become such pursuant to the  provisions of the Indenture  referred to
herein and  thereafter  "Company"  shall mean such successor  corporation),  for
value received, hereby promises to pay to Cede & Co., or registered assigns, the
principal sum of THREE HUNDRED MILLION DOLLARS  ($300,000,000) on March 15, 2007
(the  "Stated  Maturity  Date"),  unless  redeemed in full prior to such date in
accordance  with the  provisions  specified  herein,  and to pay interest on the
outstanding principal amount hereof from March 25, 2002, or from the most recent
Interest  Payment  Date to which  interest has been paid or duly  provided  for,
semiannually on March 15 and September 15 in each year, commencing September 15,
2002,  at the rate of 5 1/2% per annum,  until the  principal  hereof is paid or
made duly available for payment.

     The interest so payable,  and punctually  paid or duly provided for, on any
Interest Payment Date will, as provided in the Indenture,  be paid to the Person
in  whose  name  this  Security  (or  one or  more  Predecessor  Securities)  is
registered  at the  close  of  business  on the  Regular  Record  Date  for such
interest,  which shall be (in each case whether or not a Business Day) the March
1 or September 1 as the case may be, next preceding such Interest  Payment Date.
Any interest not

<Page>

punctually  paid or duly provided for shall forthwith cease to be payable to the
Holder on such Regular Record Date and may either be paid to the Person in whose
name this Security (or one or more Predecessor  Securities) is registered at the
close of  business on a Special  Record  Date for the payment of such  Defaulted
Interest to be fixed by the Trustee referred to herein,  notice whereof shall be
given to Holders  of  Securities  of this  series not less than 10 days prior to
such Special  Record Date, or be paid at any time in any other lawful manner not
inconsistent  with the  requirements  of any  securities  exchange  on which the
Securities of this series may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in said Indenture.

     Payment of the principal of and Make-Whole  Amount, if any, and interest on
this Security will be made in immediately available funds at the corporate trust
office of U.S.  Bank  National  Association  in St.  Paul,  Minnesota  or in the
Borough of  Manhattan,  in The City of New York, in such coin or currency of the
United  States of America as at the time of payment is legal  tender for payment
of public and private debts.

     This Security is one of a duly  authorized  issue of debt securities of the
Company (the "Debt  Securities"),  issued and to be issued in one or more series
under an Indenture,  dated as of October 26, 2001, as  supplemented by the First
Supplemental  Indenture thereto, dated as of March 20, 2002 (as so supplemented,
the  "Indenture,"  which  term  includes  any  future  indentures   supplemental
thereto),  between the Company and U.S.  Bank National  Association,  as Trustee
(the "Trustee," which term includes any successor  trustee or trustees under the
Indenture),  to which Indenture  reference is hereby made for a statement of the
respective rights,  limitations of rights,  duties and immunities  thereunder of
the Company, the Trustee and the Holders of the Debt Securities and of the terms
upon which the Debt Securities are, and are to be,  authenticated and delivered.
This  Security  is one of the series of Debt  Securities  designated  as "5 1/2%
Senior  Notes  due March 15,  2007"  (the  "Securities")  limited  initially  in
aggregate  principal  amount to  $300,000,000,  subject to the provisions of the
Indenture.

     This Security shall be redeemable at the option of the Company, at any time
in whole or from time to time in part, at a Redemption Price equal to the sum of
100% of the  aggregate  principal  amount  being  redeemed,  accrued  but unpaid
interest thereon to the Redemption Date, and the Make-Whole Amount, if any, with
respect  thereto;  provided,  however,  that  installments  of  interest on this
Security  due  on an  Interest  Payment  Date  which  occurs  on or  before  any
Redemption  Date shall be payable to the Holder of this Security as of the close
of business  on the Regular  Record Date  immediately  preceding  such  Interest
Payment  Date.  If the Company has given notice as provided in the Indenture and
made funds available for redemption of this Security if called for redemption on
the  Redemption  Date,  this  Security  will  cease  to  bear  interest  on that
Redemption  Date and the only  right of the Holder of this  Security  will be to
receive payment of the Redemption  Price.  The Company shall give written notice
of any  redemption  of this  Security  to the  Holder  of this  Security  at the
addresses of such Holder,  as shown in the Security  Register,  not more than 60
nor less than 30 days prior to the  Redemption  Date.  The notice of  redemption
will  specify,  among  other  items,  the  Redemption  Price  and the  aggregate
principal  amount  of the  Securities  to be

<Page>

redeemed.  If less than all of the  Outstanding  Securities  are to be redeemed,
then the Trustee shall select the Securities to be redeemed in principal amounts
of $1,000 or integral  multiples of $1,000 by lot, pro rata or by another method
the Trustee considers fair and appropriate.

     Notwithstanding  anything  contained  in the  Indenture  to  the  contrary,
"Make-Whole Amount", "Reinvestment Rate" and "Statistical Release", as used with
respect to this Security, shall have the following meaning:

     "Make Whole  Amount"  means,  in  connection  with any  redemption  of this
Security,  the excess, if any, of (a) the aggregate present value as of the date
of such  redemption  of each dollar of principal  hereof being  redeemed and the
amount of  interest,  exclusive of interest  accrued to the date of  redemption,
that would have been  payable in respect of each such dollar if such  redemption
had not been made,  determined  by  discounting,  on a  semiannual  basis,  such
principal  and  interest  at the  Reinvestment  Rate,  determined  on the  third
Business Day  preceding the date notice of such  redemption  is given,  from the
respective dates on which such principal and interest would have been payable if
such  redemption  had not been  made,  to the date of  redemption,  over (b) the
aggregate principal hereof being redeemed.

     "Reinvestment Rate" means .15% plus the arithmetic mean of the yields under
the heading "Week Ending" published in the most recent Statistical Release under
the caption  "Treasury  Constant  Maturities"  for the maturity,  rounded to the
nearest  month,  corresponding  to the  remaining  life to  maturity,  as of the
redemption date, of the principal hereof being redeemed.  If no maturity exactly
corresponds  to such  maturity,  yields for the two  published  maturities  most
closely  corresponding  to such  maturity  shall be  calculated  pursuant to the
immediately  preceding  sentence and the Reinvestment Rate shall be interpolated
or extrapolated from such yields on a straight-line  basis,  rounding in each of
such relevant  periods to the nearest month. For the purposes of calculating the
Reinvestment  Rate, the most recent  Statistical  Release published prior to the
date of determination  of the Make-Whole  Amount shall be used. If the format or
content  of  the  Statistical   Release  changes  in  a  manner  that  precludes
determination of the Treasury yield in the above manner, then the Treasury yield
shall be  determined  in the manner  that most  closely  approximates  the above
manner, as reasonably determined by the Company.

     "Statistical Release" means the statistical release designated  "H.15(519)"
or any successor  publication  which is published  weekly by the Federal Reserve
System and which reports  yields on actively  traded  United  States  Government
securities adjusted to constant  maturities,  or, if such statistical release is
not  published at the time of any required  determination  under the  Indenture,
then such other  reasonably  comparable  index which shall be  designated by the
Company.

     Interest  payable on this  Security on any Interest  Payment  Date,  Stated
Maturity  Date and  Redemption  Date,  as the case may be, will be the amount of
interest accrued during the applicable Interest Period.

     An  "Interest  Period" is each period from and  including  the  immediately
preceding  Interest

<Page>

Payment  Date (or from and  including  March 25, 2002 in the case of the initial
Interest Period) to but excluding the applicable  Interest Payment Date,  Stated
Maturity  Date or the  Redemption  Date,  as the  case may be.  If any  Interest
Payment Date, Stated Maturity Date or Redemption Date falls on a day that is not
a Business Day,  principal,  Make-Whole  Amount, if any, and interest payable on
such date will be paid on the  succeeding  Business  Day with the same force and
effect as if it were paid on the date such payment was due, and no interest will
accrue on the amount so payable  for the period from and after such date to such
succeeding Business Day.

     "Business Day" means any day,  other than a Saturday or a Sunday,  on which
banking institutions in New York, New York are not required or authorized by law
or executive order to close.

     If an Event of  Default  with  respect  to  Securities  shall  occur and be
continuing,  the principal of the Securities may, and in certain cases, shall be
declared  due and  payable in the manner  and with the  effect  provided  in the
Indenture.

     The Indenture  permits,  with certain  exceptions as therein provided,  the
amendment  thereof and the  modification  of the rights and  obligations  of the
Company and the rights of the Holders of the Debt  Securities  of each series to
be affected  under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of not less than a majority  in  principal  amount of
the Securities at the time  Outstanding of all series to be affected  (voting as
one class).  The Indenture also provides that,  regarding the Debt Securities of
any series,  the Holders of not less than a majority in principal  amount of the
Debt  Securities at the time  Outstanding  of such series may waive certain past
defaults and their  consequences on behalf of the Holders of all Debt Securities
of such series.  Any such consent or waiver by the Holder of this Security shall
be conclusive  and binding upon such Holder and upon all future  Holders of this
Security and of any Security issued upon the  registration of transfer hereof or
in exchange  herefor or in lieu hereof,  whether or not notation of such consent
or waiver is made upon this Security.

     No reference  herein to the Indenture and no provisions of this Security or
of the Indenture  shall alter or impair the obligation of the Company,  which is
absolute and  unconditional,  to pay the principal of and any Make-Whole  Amount
and interest on this Security at the times,  place and rate,  and in the coin or
currency,  herein  and in  the  Indenture  provided;  subject,  however,  to the
provisions  for the  discharge  of the Company  from its  obligations  under the
Securities upon satisfaction of the conditions set forth in the Indenture.

     As provided in the Indenture and subject to certain  limitations herein and
therein set forth,  the transfer of this Security is registrable in the Security
Register,  upon surrender of this Security for  registration  of transfer at the
office  or agency  of the  Company  in any  place  where  the  principal  of and
Make-Whole Amount, if any, and interest on this Security are payable,  when duly
endorsed  by,  or  accompanied  by a  written  instrument  of  transfer  in form
satisfactory  to the Company and the Security  Registrar  duly  executed by, the
Holder hereof or his attorney duly  authorized in writing,  and thereupon one or
more  new  Securities,  of  authorized  denominations  and for a like  aggregate
principal  amount  and  tenor  will be issued to the  designated  transferee  or
transferees.

<Page>

     The  Securities  are issuable  only in registered  form without  coupons in
denominations  of $1,000 and any larger  amount that is an integral  multiple of
$1,000. As provided in the Indenture and subject to certain  limitations  herein
and  therein  set  forth,  Securities  are  exchangeable  for a  like  aggregate
principal amount and tenor of Securities of a different authorized denomination,
upon  surrender of the Securities to be exchanged at the office or agency of the
Company in any place where the principal of and Make-Whole  Amount,  if any, and
interest on this Security are payable .

     No  service  charge  shall  be made for any  registration  of  transfer  or
exchange  of this  Security,  but  the  Company  may  require  payment  of a sum
sufficient to cover any tax or other  governmental  charge payable in connection
therewith.

     Prior to due presentment of this Security for registration of transfer, the
Company,  the  Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this  Security is  registered  as the owner  hereof for all
purposes,  whether or not this Security be overdue, and none of the Company, the
Trustee or any such agent shall be affected by notice to the contrary.

     This Security is not subject to a sinking fund requirement.

     As provided in the  Indenture,  no recourse shall be had for the payment of
the principal of or Make-Whole  Amount or the interest on this Security,  or any
part hereof, or for any claim based hereon or otherwise in respect hereof, or of
the  indebtedness  represented  hereby,  or upon  any  obligation,  covenant  or
agreement of the Company in the Indenture,  against any incorporator,  direct or
indirect stockholder,  officer or director, as such, past, present or future, of
the  Company or of any  successor  corporation  (either  directly or through the
Company  or  any  such  successor   corporation),   whether  by  virtue  of  any
constitutional  provision,  statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise,  all  liability,  if any, of that  character
against every such incorporator,  stockholder, officer and director being by the
acceptance  hereof,  and as a condition of and as part of the  consideration for
the issue hereof, expressly waived and released.

     The  Indenture  and this  Security  shall be governed by and  construed  in
accordance with the laws of the State of New York.

     Except as otherwise  provided herein, all terms used in this Security which
are defined in the  Indenture  shall have the  meanings  assigned to them in the
Indenture.

     Unless the  certificate of  authentication  hereon has been executed by the
Trustee by manual signature,  this Security shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.
