                                   ALCAN INC.

                                4-7/8% NOTE DUE 2012

         This Note is one of a duly authorized issue of debentures, notes, bonds
or other evidences of indebtedness of the issuer (hereinafter called the
"Securities") of the series hereinafter specified, all issued or to be issued
under and pursuant to an indenture dated May 15, 1983 (herein called the
"Indenture"), duly executed and delivered by the Issuer to Deutsche Bank Trust
Company Americas (formerly known as Bankers Trust Company), Trustee (herein
called the "Trustee"), 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 a series designated as
the 4-7/8% Notes Due 2012 of the Issuer, limited in aggregate principal amount
to $500,000,000.

         The Issuer may, at any time, and from time to time, issue additional
notes under the Indenture in unlimited amounts having the same terms as this
Note, and such additional notes will, together with this Note and any Notes
which may be issued in exchange or substitution herefor, constitute a single
series of Securities under the Indenture.

         In case an Event of Default with respect to the 4-7/8% Notes due
September 15, 2012, as defined in the Indenture, shall have occurred and be
continuing, the principal hereof 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 66-2/3% in aggregate
principal amount of the Securities at the time Outstanding (as defined in the
Indenture) 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 (i) extend the final maturity of any Security, or
reduce the principal amount thereof or any premium thereon, or reduce the rate
or extend the time of payment of any interest thereon, 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
affected. It is also provided in the Indenture that the Holders of a majority in
aggregate principal amount Outstanding of the Securities of each series may,
prior to any declaration accelerating the maturity of each Securities, on behalf
of the Holders of all the Securities of such series waive compliance by the
Issuer with certain provisions of the Indenture and any such past default or
Event of Default and its consequences and may, after any such declaration, waive
such declaration and

                                      -4-


its consequences. The preceding sentence shall not, however, apply to a default
in the payment of the principal of or premium, if any, or interest on any of the
Securities. 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, 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

or currency herein prescribed.

payment of any service charge, Notes may be exchanged for a like aggregate
principal. amount of Notes of other authorized denominations.

             (as defined in the Prospectus Supplement dated September 5, 2002
             relating to the Notes) discounted to the redemption date on a
             semiannual basis at the Treasury Rate (as defined in the Prospectus
             Supplement dated September 5, 2002 relating to the Notes) plus 20
             basis points.

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
