<p class="MsoNormal" style="text-align: justify">
&nbsp;</p>
<p class="MsoNormal" style="text-align: justify">
On July 12, 2007, Alcan entered into
a support agreement (the &quot;Support Agreement&quot;) with Rio Tinto plc (&quot;Rio&quot;) and Rio
Tinto Canada Holding Inc. (&quot;Offeror&quot;).&nbsp; Pursuant to the Support Agreement, among
other things, Offeror has agreed to make a cash tender offer to acquire all
outstanding common shares of Alcan (the &quot;Offer&quot;) for a purchase price per Alcan
common share of $101. Alcan has agreed to recommend that its shareholders accept
that Offer.&nbsp; </p>
<p class="MsoNormal" style="text-align: justify">
The Support Agreement was approved
by both Alcan's board of directors and Rio's board of directors. It contains
customary representations, warranties and covenants. </p>
<p class="MsoNormal" style="text-align: justify">
Offeror's obligation to make the
Offer is subject to the satisfaction or waiver of certain conditions, including
a condition that certain regulatory approvals have been obtained and the absence
of a material adverse effect (as defined in the Support Agreement) with respect
to Alcan and its subsidiaries. The obligation of Offeror to consummate the Offer
is also subject to the satisfaction or waiver of certain conditions, including a
condition that certain regulatory approvals have been obtained, a condition that
at least 66 2/3% of the fully diluted outstanding shares of common stock of
Alcan have been validly tendered and not withdrawn as at the expiration of the
Offer, the absence of a material adverse effect with respect to Alcan and its
subsidiaries, and affirmative shareholders' votes on approval of the Offer. </p>
<p class="MsoNormal" style="text-align: justify">
Subject to the terms and conditions
of the Support Agreement, Alcan's board of directors has the right to withdraw,
modify or change its support of the Offer if Alcan receives a superior proposal
(as defined in the Support Agreement) prior to the expiration of the Offer.&nbsp;
However, Offeror has the right to match any such superior proposal received by
Alcan and, in certain circumstances, if the Offer is not consummated, Offeror
would have the right to receive a payment of U.S. $1,049 million from Alcan.&nbsp; In
other circumstances, related to the required shareholder votes for the Rio Tinto
group, an equivalent payment from Rio Tinto may be required.</p>
<p class="MsoNormal" style="text-align: justify">
The above summary of the Support
Agreement is qualified in its entirety by reference to the Support Agreement,
which is filed as Exhibit 99.1 hereto and is incorporated herein by reference.
