     Employee's awareness of their role in improving shareholder value, the
     Committee has approved an executive total compensation plan that recognizes
     that long-term incentives are an integral part of the executive's
     compensation.

3.2. Purpose. The purpose of the Plan is to promote the achievement of long-term
     objectives of the Company i) by tying the Key Employee's long-term
     incentive opportunities to pre-established goals; ii) by rewarding
     performance, based on the successful achievement of the pre-established
     goals; and iii) by attracting, retaining and motivating highly competent
     Key Employees committed as a group to achieve results through teamwork.

4.1. The Plan shall be administered by the Committee. The Committee shall have
     full and complete authority to interpret the Plan and prescribe such rules
     and regulations and make such other determinations as it deems necessary or
     desirable for the administration of the Plan.

4.2. Amendment, Modification and Termination. The Committee may at any time and
     from time to time amend, suspend or terminate the Plan in whole or in part.

4.3. Costs of the Plan. All expenses associated with the establishment,
     maintenance and termination of the Plan shall be borne by the Company.

4.4. Tax Consequences. The Awards shall be subject to taxes as per the income
     tax rules of the Key Employee's country of residence. Participants are
     encouraged to inform themselves of their particular tax situation. All
     taxes shall be paid by the Participant.

4.5. Successors. All obligations of the Company under the Plan shall be binding
     on any successor to the Company.


5.   ELIGIBILITY

5.1. Eligibility. The Plan provides for the granting of a Target Cash Award to
     designated Key Employees of the Company and its Subsidiaries. The Committee
     shall determine at its sole discretion, which Key Employees of the Company
     shall be eligible to be granted a TSR performance Target Cash Award. It
     shall also determine the conditions (amount, period) applicable to each
     Award.

     Eligibility to participate in the Plan does not confer a right to receive a
     Target Cash Award. There is no automatic entitlement to any grant.

6.   AWARDS

6.1. Target Cash Award. The target amount of the Key Employee's Target Cash
     Award shall be determined through competitive market data using appropriate
     peer companies. The Committee shall approve annually the target long-term
     incentive compensation amount to be attributed to Key Employees. Half of
     this amount shall be delivered through the Plan and the other half through
     the Alcan Executive Share Option Plan. Employees eligible for participation
     in the Alcan LTIP but not eligible to participate in this Plan shall
     receive their long-term compensation amount entirely through the Alcan
     Executive Share Option Plan.

6.2. Amount of the Award. The amount of the Award, if any, shall be based on the
     Company's TSR performance at the end of the Performance Period as measured

                                        4

================================================================================

     against the TSR performance of the S&P Industrials.

6.3. Award Frequency and Performance Period. Subject to the terms of the Plan
     (including sections 4.1, 4.2 and 5.1), Target Cash Awards shall generally
     be granted annually by the Committee, with each Target Cash Award having a
     Performance Period of 3 years.

6.4. Total Shareholder Return and Performance Measure. TSR shall be measured as
     a change in the market price of the common stock plus cumulative dividend
     yield over the Performance Period.

     At the end of the Performance Period, the TSR performance measurement shall
     be made for all companies in the S&P Industrials Index and the Company's
     performance will be ranked relative to the other industrial companies in
     the Index as of the end of the Performance Period. These measurements will
     be made by a third party and audited by the Company's Auditors.

6.5. Calculation of TSR Performance. The percentage change in stock price is
     equal to the ratio of (A) the average of the Closing Prices over the five
     trading days immediately preceding the end of the Performance Period over
     (B) the average of the Closing Prices over the five trading days
     immediately preceding the commencement of the Performance Period.

     Only companies that have been part of the Index for the full Performance
     Period shall be included in the calculation of TSR performance.

6.6. Payout Matrix. In order for any payout to be earned, the Company's TSR
     performance shall be at or above the 30th percentile rank of the companies
     ranked in the S&P Industrial Index. At the 30th percentile rank, a payout
     of 60% of the target Award shall be earned. At the 50th percentile rank, a
     payout of 100% of target Award shall be earned, and at the 75th percentile
     rank, a payout of 300% of the target Award shall be earned (maximum
     payout). The payout will be prorated between these rankings (see sample
     calculation at Appendix A).

6.7. Individual Performance. As with other elements of compensation, an Award
     shall be earned through individual performance. There shall be no
     entitlement to an Award. The actual target Award may also be subject to an
     upward or downward adjustment based on the individual's performance and
     contribution to the Company.

6.8. Payment of Awards. Subject to applicable law, payment with respect to
     earned Awards may be made in whole or in part in the form of cash and/or
     Shares of the Company, at the sole discretion of the Committee.

6.9. Award Agreement. A separate Agreement shall be entered into between the
     Company and the Participant to cover each Target Cash Award. This document
     shall be sent in duplicate to each Participant for signature. It describes
     the conditions applying to that particular Award (see Appendix B).

     normally due and in accordance with such rules and regulations as may be

     partial payment as above.


8.   BENEFICIARY DESIGNATION

8.1. Designation of Beneficiary. Each Participant shall advise the Company in a

NAME                                                 AWARD YEAR:


PERFORMANCE PERIOD:                                  TARGET AWARD AMOUNT:


You have been granted a 2002 Target Cash Award (shown above) under the TSR
Performance Plan. This Award was approved by the Personnel Committee of the
Board, effective 15 September 2002 and is subject to a three year Performance
Period beginning 1 January 2003 and ending 31 December 2005.

The payment value of this Award, if any, will be calculated on the Total
Shareholder Return and Alcan's percentile rank relative to the Standard and Poor
(S&P) Industrials at the end of the Performance Period. Total Shareholder Return
is measured as the change in the market price of the common stock plus
cumulative dividend yield over the Performance Period. The percentage change in
stock price is equal to the ratio of (A) the average of the closing share prices
over the five trading days immediately preceding the end of the Performance
Period over (B) the average of the closing share prices over the five trading
days immediately preceding the Performance Period.

At the end of the Performance Period, TSR performance measurements will be made
for Alcan and for all companies in the S&P Industrials Index. Alcan's TSR
performance will be compared and ranked against the TSR performance of other
industrial companies in the Index. Only companies that have been part of the
Index for the full 3-year period will be included in the Index.

The payout, if any, will be calculated by adjusting the target award by a
performance factor related to Alcan's percentile rank relative to the S&P
Industrials as follows:

o    At a relative rank below the 30th percentile no payout will be made

o    At a relative rank of the 30th percentile a payout of 60% of the target
     amount

o    At a relative rank of the 50th percentile a payout of 100% of the target
     amount

o    At a relative rank of the 75th percentile a payout of 300% of the target
     amount (300% is the maximum payout under the Schedule)

o    The payout will be prorated between these rankings.

period to be eligible to receive any payment. The actual payment, if any, will
be made as soon as practicable following completion of the Performance Period.

period up to termination; the amount being paid at the prescribed time and
