      WEYERHAEUSER COMPANY, a Washington corporation (the "Issuer," which term
includes any successor thereto under the Indenture referred to below), for value
received, hereby promises to pay to --, or registered assigns, at the office
or agency of the Issuer maintained for such purpose in the Borough of Manhattan,
The City of New York, the principal sum of -- Dollars ($--,000,000) on
December 15, 2009, in such coin or currency of the United States of America as
at the time of payment shall be legal tender for the payment of public and
private debts, and to pay interest, semiannually in arrears on June 15 and
December 15 of each year, commencing June 15, 2003, and at final maturity on
said principal sum at said office or agency, in like coin or currency, at the
rate of 5.25% per annum from the June 15 or December 15, as the case may be,
next preceding the date of this Note to which interest has been paid or duly

                                      -1-
<PAGE>

provided for, unless the date hereof is a date to which interest has been paid
or duly provided for, in which case from the date of this Note, or unless no
interest has been paid or duly provided for on these Notes, in which case from
December 17, 2002, until payment of said principal sum has been made or duly
provided for; provided that, if this Note is not a Global Security, payment of
interest may be made at the option of the Issuer by check mailed to the address
of the Person entitled thereto as such address shall appear on the Security
register; and provided, further, that if this Note is a Global Security
registered in the name of a Depositary or its nominee, payment of interest shall
be made to the Depositary or its nominee, as the case may be, in accordance with
the Depositary's procedures as in effect from time to time. Notwithstanding the
foregoing, if the date hereof is after June 1 or December 1, as the case may be,
and before the following June 15 or December 15, this Note shall bear interest
from such June 15 or December 15; provided, that if the Issuer shall default in
the payment of interest due on such June 15 or December 15, then this Note shall
bear interest from the next preceding June 15 or December 15 to which interest
has been paid or duly provided for or, if no interest has been paid or duly
provided for on these Notes, from December 17, 2002. The interest so payable on
any June 15 or December 15 will, subject to certain exceptions provided in the
Indenture referred to below, be paid to the Person in whose name this Note is
registered at the close of business on June 1 or December 1, as the case may be,
next preceding such June 15 or December 15. Interest on this Note shall be
calculated on the basis of a 360-day year consisting of twelve 30-day months.

      This Note is one of a duly authorized issue of Securities of the Issuer
issued under and pursuant to an Indenture dated as of April 1, 1986 (the
"Original Indenture"), as amended and supplemented by a First Supplemental
Indenture thereto dated as of February 15, 1991 (the "First Supplemental
Indenture"), a Second Supplemental Indenture thereto dated as of February 1,
1993 (the "Second Supplemental Indenture"), a Third Supplemental Indenture
thereto dated as of October 22, 2001 (the "Third Supplemental Indenture") and a
Fourth Supplemental Indenture thereto dated as of March 12, 2002 (the "Fourth
Supplemental Indenture;" the Original Indenture, as amended and supplemented by
the First Supplemental Indenture, the Second Supplemental Indenture, the Third
Supplemental Indenture, the Fourth Supplemental Indenture and any other
indentures supplemental thereto, is hereinafter called the "Indenture"), each
duly executed and delivered by the Issuer to JPMorgan Chase Bank (formerly known
as The Chase Manhattan Bank and Chemical Bank), as trustee (herein called the
"Trustee," which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Issuer and the Holders of the
Securities. The Securities may be issued in one or more series, which different
series may be issued in various aggregate principal amounts, may mature at
different times, may bear interest (if any) at different rates, may be subject
to different redemption provisions (if any), may be subject to different
sinking, purchase or analogous funds (if any) and may otherwise vary as in the
Indenture provided. This Note is one of the series of Securities designated on
the face hereof (the "Notes").

      The Notes may be redeemed, in whole or from time to time in part, at the
option of the Issuer on any date at a redemption price equal to the greater of:

      (1)   100% of the principal amount of the Notes to be redeemed, and

                                      -2-
<PAGE>

      (2)   the sum of the present values of the remaining scheduled payments of
            principal and interest on the Notes to be redeemed (exclusive of
            interest accrued to the applicable Redemption Date) discounted to
            that Redemption Date on a semi-annual basis (assuming a 360-day year
            consisting of twelve 30-day months) at the Treasury Rate plus 25
            basis points,

plus, in the case of both clause (1) and clause (2) above, accrued and unpaid
interest on the principal amount of the Notes being redeemed to such Redemption
Date; provided, however, that payments of interest on the Notes that are due and
payable on or prior to a date fixed for redemption of Notes will be payable to
the Holders of those Notes registered as such at the close of business on the
relevant record dates according to their terms and the terms and provisions of
the Indenture. Any such redemption shall be effected in accordance with the
terms and conditions set forth in the Indenture.

       As used in this Note, the following terms have the meanings set forth
       below:

      "Treasury Rate" means, with respect to any Redemption Date for the Notes,

      (1)   the yield, under the heading that represents the average for the
            immediately preceding week, appearing in the most recently published
            statistical release designated "H.15(519)" or any successor
            publication which is published weekly by the Board of Governors of
            the Federal Reserve System and which establishes yields on actively
            traded United States Treasury securities adjusted to constant
            maturity under the caption "Treasury Constant Maturities," for the
            maturity corresponding to the Comparable Treasury Issue (if no
            maturity is within three months before or after the Final Maturity
            Date for the Notes, yields for the two published maturities most
            closely corresponding to the Comparable Treasury Issue shall be
            determined and the Treasury Rate shall be interpolated or
            extrapolated from such yields on a straight line basis, rounding to
            the nearest month), or

      (2)   if such release (or any successor release) is not published during
            the week preceding the calculation date or does not contain such
            yields, the rate per annum equal to the semi-annual equivalent yield
            to maturity of the Comparable Treasury Issue, calculated using a
            price for the Comparable Treasury Issue (expressed as a percentage
            of its principal amount) equal to the Comparable Treasury Price for
            such Redemption Date.

The Treasury Rate shall be calculated on the third Business Day preceding the
applicable Redemption Date. As used in the immediately preceding sentence and in
the definition of "Reference Treasury Dealer Quotations" below, the term
"Business Day" means each Monday, Tuesday, Wednesday, Thursday and Friday that
is not a day on which banking institutions in The City of New York are
authorized or obligated by law, regulation or executive order to close.

      "Comparable Treasury Issue" means, with respect to any Redemption Date for
the Notes, the United States Treasury security selected by the Independent
Investment Banker as having a maturity comparable to the remaining term of the
Notes to be redeemed that would be utilized, at the time of selection and in
accordance with customary financial practice, in pricing new issues


                                      -3-
<PAGE>

of corporate debt securities of comparable maturity to the remaining term of the
Notes to be redeemed.

      "Comparable Treasury Price" means, with respect to any Redemption Date for
the Notes, (1) the average of four Reference Treasury Dealer Quotations for such
Redemption Date, after excluding the highest and lowest such Reference Treasury
Dealer Quotations, or (2) if the Trustee obtains fewer than four such Reference
Treasury Dealer Quotations, the average of all such quotations.

      "Final Maturity Date" means December 15, 2009.

      "Independent Investment Banker" means, with respect to any Redemption Date
for the Notes, Morgan Stanley & Co. Incorporated and its successors or J.P.
Morgan Securities Inc. and its successors, whichever shall be selected by the
Trustee after consultation with the Issuer, or, if both such firms or the
respective successors, if any, to such firms, as the case may be, are unwilling
or unable to select the Comparable Treasury Issue, an independent investment
banking institution of national standing appointed by the Trustee after
consultation with the Issuer.

      "Redemption Date" means, with respect to any Note or portion thereof to be
redeemed, the date fixed for such redemption pursuant to the Indenture and the
Notes.

      "Reference Treasury Dealers" means, with respect to any Redemption Date
for the Notes, Morgan Stanley & Co. Incorporated and J.P. Morgan Securities Inc.
and their respective successors (provided, however, that if any such firm or any
such successor, as the case may be, shall cease to be a primary U.S. Government
securities dealer in New York City (a "Primary Treasury Dealer"), the Trustee,
after consultation with the Issuer, shall substitute therefor another Primary
Treasury Dealer), and two other Primary Treasury Dealers selected by the Trustee
after consultation with the Issuer.

      "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any Redemption Date for the Notes, the average, as
determined by the Trustee, of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Trustee by that Reference Treasury Dealer at 5:00 p.m.,
New York City time, on the third Business Day preceding that Redemption Date.

      Notice of any redemption will be mailed at least 30 days but not more than
60 days before the applicable Redemption Date to each Holder of the Notes to be
redeemed at the Holder's registered address. If less than all the Notes are to
be redeemed at the option of the Issuer, the Trustee will select, in a manner it
deems fair and appropriate, the Notes, or portions of the Notes, to be redeemed.

      Unless the Issuer defaults in payment of the redemption price (including
interest accrued to the applicable Redemption Date), on and after the applicable
Redemption Date interest will cease to accrue on the Notes or portions of the
Notes called for redemption on that Redemption Date.

      Notwithstanding the provisions of Section 12.2 of the Indenture, any
notice of redemption of the Notes need not set forth the redemption price but
only the manner of

                                      -4-
<PAGE>
calculation thereof. The Issuer will notify the Trustee of the redemption price
promptly after the calculation thereof. The Trustee shall have no responsibility
for such calculation.

      In case an Event of Default (as defined in the Indenture) with respect to
the Notes shall have occurred and be continuing, the principal hereof and
accrued and unpaid interest hereon may be declared, and upon such declaration
shall become, due and payable, in the manner, with the effect and subject to the
conditions provided in the Indenture.

      The Indenture contains provisions permitting the Issuer and the Trustee,
with the consent of the Holders of not less than a majority in aggregate
principal amount of the Securities at the time Outstanding of all series to be
affected (voting as one class), evidenced as in the Indenture provided, to
execute supplemental indentures adding any provisions to or changing in any
manner or eliminating any of the provisions of the Indenture or of any
supplemental indenture or modifying in any manner the rights of the Holders of
the Securities of each such series; provided, that no such supplemental
indenture shall, among other things, (i) extend the final maturity of any
Security, or reduce the principal amount thereof or reduce the rate or extend
the time of payment of any interest thereon, or reduce any amount payable on the
redemption thereof, or make the principal thereof or the interest thereon
payable in any coin or currency other than that provided in the Securities or in
accordance with the terms thereof, or impair or affect the rights of any Holder
to institute suit for the payment thereof, without the consent of the Holder of
each Security so affected, or (ii) reduce the aforesaid percentage of Securities
the Holders of which are required to consent to any such supplemental indenture
without the consent of the Holder of each Security so affected. It is also
provided in the Indenture that, with respect to certain defaults or Events of
Default, prior to any declaration accelerating the maturity of the Securities of
any series, the Holders of a majority in aggregate principal amount of the
Outstanding Securities of such series (or, in the case of certain defaults or
Events of Default, all or certain series of the Securities) may on behalf of the
Holders of all the Securities of such series (or all or certain series of the
Securities, as the case may be) waive any such past default or Event of Default
and its consequences. The preceding sentence shall not, however, apply to a
default or Event of Default in respect of the payment of the principal of or
premium, if any, or interest on any of the Securities or a default or Event of
Default in respect of a covenant or provision of the Indenture which cannot be
modified or amended without the consent of the Holder of each Security affected.
Any such consent or waiver by the Holder of this Note (unless revoked as
provided in the Indenture) shall be conclusive and binding upon such Holder and
upon all future Holders and owners of this Note and any Notes which may be
issued in exchange or substitution herefor or on registration of transfer
hereof, irrespective of whether or not any notation thereof is made upon this
Note or such other Notes.

      No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of and premium, if any, and
interest on this Note in the manner, at the respective times, at the rate and in
the coin or currency herein prescribed.

      The Notes are issuable in registered form without coupons in denominations
of $1,000 and any integral multiple of $1,000. Notes may be exchanged for a like
aggregate principal amount of Notes of other authorized denominations upon
surrender of the Notes to be exchanged at the agency of the Issuer maintained
for that purpose in the Borough of Manhattan, The City of


                                      -5-
<PAGE>
New York in the manner and subject to the limitations provided in the Indenture,
without charge except for any tax or other governmental charge that may be
imposed in connection therewith.

      The Notes are not subject to any sinking fund.

      Upon due presentment for registration of transfer of this Note at the
agency of the Issuer maintained for that purpose in the Borough of Manhattan,
The City of New York, a new Note or Notes of authorized denominations for an
equal aggregate principal amount will be issued to the transferee in exchange
therefor, subject to the limitations provided in the Indenture, without charge
except for any tax or other governmental charge that may be imposed in
connection therewith.

      The Issuer, the Trustee and any authorized agent of the Issuer or the
Trustee may deem and treat the registered Holder hereof as the absolute owner of
this Note (whether or not this Note shall be overdue and notwithstanding any
notation of ownership or other writing hereon), for the purpose of receiving
payment of, or on account of, the principal hereof and premium, if any, and,
subject to the provisions of the first paragraph hereof, interest hereon and for
all other purposes, and neither the Issuer nor the Trustee nor any authorized
agent of the Issuer or the Trustee shall be affected by any notice to the
contrary.

      No recourse under or upon any obligation, covenant or agreement of the
Issuer in the Indenture or in any Note, or because of any indebtedness
represented thereby, shall be had against any incorporator, stockholder, officer
or director, as such, of the Issuer or of any successor entity, either directly
or through the Issuer or any successor entity, under any rule of law, statute or
constitutional provision or by the enforcement of any assessment or by any legal
or equitable proceeding or otherwise, all such liability being expressly waived
and released by the acceptance hereof and as part of the consideration for the
issue hereof.

      This Note shall be governed by and construed in accordance with the laws
of the State of New York, except as may otherwise be required by mandatory
provisions of law.

      Terms used in this Note which are defined in the Indenture shall have the
respective meanings assigned thereto in the Indenture.

      The Indenture contains provisions whereby the Issuer may be discharged
from its obligations with respect to the Notes, subject to exceptions, if the
Issuer deposits with the Trustee cash or U.S. Government Obligations in the
amount and in the manner, and satisfies certain other conditions, as in the
Indenture provided.

      This Note shall not be valid or obligatory for any purpose until the
certificate of authentication hereon shall have been signed by or on behalf of
the Trustee under the Indenture by manual signature of an authorized officer of
the Trustee.
