Shareholders who have validly deposited and not withdrawn their Alcan Common Shares need take no further action to accept the Offer. Any Alcan shareholder desiring to deposit all or any portion of such Alcan shareholder’s Alcan Common Shares under the Offer should either (i) complete and sign the Letter of Transmittal (printed on green paper) that accompanied the Offer and Circular, or a manually signed facsimile copy thereof, in accordance with the instructions in the Letter of Transmittal and mail or deliver it together with the certificate(s) evidencing deposited Alcan Common Shares, and any other required documents, to Computershare Investor Services Inc. (the “Depositary”) at any of its offices specified in the Letter of Transmittal, (ii) deposit such Alcan Common Shares pursuant to the procedures for book-entry transfer set forth in the section of the Offer entitled “Offer — Manner of Acceptance,” or (iii) request such Alcan shareholder’s broker, dealer, commercial bank, trust company or other nominee to effect the transaction for such Alcan shareholder. Any Alcan shareholder whose Alcan Common Shares are registered in the name of a broker, dealer, commercial bank, trust company or other nominee must contact such broker, dealer, commercial bank, trust company or other nominee if such Alcan shareholder desires to deposit such Alcan Common Shares in the Offer.

If an Alcan shareholder desires to deposit Alcan Common Shares pursuant to the Offer and (i) the certificates evidencing such Alcan Common Shares, and/or the Rights Certificates (as defined below) representing the Alcan Rights associated therewith, if applicable, are not immediately available, (ii) such shareholder cannot deliver the certificates and all other required documents to the Depositary before the expiration time, (iii) such shareholder cannot comply with the procedures for book-entry transfer on a timely basis, or (iv) the Separation Time (as defined under the section of the Offer entitled “Offer — Shareholder Rights Agreement”) has occurred before the expiration time but Rights Certificates have not been distributed to Alcan shareholders before the expiration time, such Alcan Common Shares may nevertheless be validly deposited under the Offer in compliance with the procedures for guaranteed delivery using the Notice of Guaranteed Delivery (printed on yellow paper) that accompanied the Offer and Circular. See the section of the Offer entitled “Offer — Manner of Acceptance.”

All payments will be made in U.S. dollars, unless the Alcan shareholder elects to receive payment in Canadian dollars by checking the appropriate box in the Letter of Transmittal and, if applicable, the Notice of Guaranteed Delivery. The amount payable in Canadian dollars will be based on the Bank of Canada Noon Rate on the business day immediately preceding the date of delivery of such payment to the Depositary.

Questions or requests for assistance may be directed to the Information Agent at its address and telephone numbers, or any of the Dealer Managers at their telephone numbers, in each case, as set forth on the back cover of this Notice of Extension. Requests for additional copies of this Notice of Extension, the Offer and Circular, the Letter of Transmittal and the Notice of Guaranteed Delivery may be directed to the Information Agent, and copies will be furnished promptly at Alcoa’s expense.

While the Offer is being made to all holders of Alcan Common Shares, the Offer does not constitute an offer or a solicitation in any jurisdiction in which such offer or solicitation is unlawful.

THIS NOTICE OF EXTENSION, THE OFFER AND CIRCULAR AND THE LETTER OF TRANSMITTAL CONTAIN IMPORTANT INFORMATION, AND YOU SHOULD CAREFULLY READ ALL OF THEM IN THEIR ENTIRETY BEFORE MAKING A DECISION WITH RESPECT TO THE OFFER.

ALCOA IS NOT ASKING ALCAN SHAREHOLDERS FOR A PROXY AND ALCAN SHAREHOLDERS ARE REQUESTED NOT TO SEND A PROXY. ANY SOLICITATION OF PROXIES WILL BE MADE ONLY PURSUANT TO SEPARATE PROXY SOLICITATION MATERIALS COMPLYING WITH APPLICABLE CANADIAN LAW.

NONE OF THE SEC, ANY STATE SECURITIES COMMISSION, ANY CANADIAN SECURITIES REGULATORY AUTHORITY OR ANY OTHER REGULATORY AUTHORITY HAS APPROVED OR DISAPPROVED OF THE SECURITIES OFFERED PURSUANT TO THE OFFER OR PASSED UPON THE ADEQUACY OR ACCURACY OF THIS DOCUMENT. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

NOTICE TO SHAREHOLDERS IN CANADA

Alcoa presents its financial statements in U.S. dollars and its financial statements are prepared in accordance with U.S. generally accepted accounting principles (referred to herein as “U.S. GAAP”). As financial information in the Offer and Circular has been prepared in accordance with U.S. GAAP, it may not be comparable to financial data prepared by other Canadian companies.

The Offer is made for the securities of a Canadian issuer and by an issuer that is permitted, under a multijurisdictional disclosure system adopted by the U.S. and Canada, to prepare the Offer and Circular, which forms the prospectus of Alcoa’s registration statement on Form S-4 relating to the Offer, in accordance with the disclosure requirements of the U.S. Shareholders should be aware that the requirements with respect to the content of such prospectus are different from those of Canada.

Securities legislation in the Province of Québec, Canada, requires that French language versions be prepared of any documents incorporated by reference in the Circular. The Autorité des marchés financiers in Québec has granted the Offerors a permanent exemption from the obligation to prepare a French language version of any information contained in a Form 10-K, 10-Q or 8-K prepared in accordance with U.S. securities legislation that is not otherwise required by Québec securities legislation and is incorporated in the Circular.

Shareholders in Canada should be aware that the disposition of Alcan Common Shares and the acquisition of Alcoa Common Shares by them as described in the Offer may have tax consequences both in Canada and the U.S. Such consequences may not be fully described in the Offer and such shareholders are encouraged to consult their tax advisors. See “Circular — Material Canadian Federal Income Tax Considerations” and “Circular — Material U.S. Federal Income Tax Considerations” in the Offer and Circular.

NOTICE TO SHAREHOLDERS IN THE U.S.

Shareholders in the U.S. should be aware that the disposition of Alcan Common Shares and the acquisition of Alcoa Common Shares by them as described in the Offer may have tax consequences both in the U.S. and in Canada. Such consequences may not be fully described in the Offer and such shareholders are encouraged to consult their tax advisors. See “Circular — Material U.S. Federal Income Tax Considerations” and “Circular — Material Canadian Federal Income Tax Considerations” in the Offer and Circular.

The enforcement by investors of civil liabilities under U.S. federal securities laws may be affected adversely by the fact that Alcoa Holdco Canada is organized under the laws of the Province of Nova Scotia, Canada, that some of the Offerors’ officers and directors may reside outside the U.S., that certain Dealer Managers and some of the experts named herein may reside outside the U.S., and that all or a substantial portion of the assets of the Offerors and such persons may be located outside the U.S.

NOTICE TO SHAREHOLDERS IN THE EUROPEAN UNION

While the Offer is being made to all holders of Alcan Common Shares, the Offer does not constitute an offer to purchase, sell or exchange or the solicitation of an offer to purchase, sell or exchange any securities of Alcan or an offer to purchase, sell or exchange or the solicitation of an offer to purchase, sell or exchange any securities of Alcoa in any jurisdiction in the European Union (the “EU”). Alcoa Common Shares may not be offered or sold in any member state of the EU except pursuant to (i) a prospectus (an “EU Prospectus”) approved by the securities regulator of competent jurisdiction in the state where the offer or sale is being made, (ii) an EU Prospectus approved by a securities regulator of competent jurisdiction of another EU member state and passported into the EU member state where the offer or sale is being made, or (iii) an exemption under the applicable securities laws under the laws of the EU member state where the offer or sale is being made. Alcoa reserves the right to make the Offer in or into one or more EU member states. Appropriate filings and prospectus publication may be undertaken by Alcoa in relation to each relevant jurisdiction.

NOTICE TO HOLDERS OF OPTIONS

The Offer is made only for Alcan Common Shares and is not made for any stock options or other rights to acquire Alcan Common Shares (other than the Alcan Rights). Any holder of stock options or other rights to acquire Alcan Common Shares (other than Alcan Rights) who wishes to accept the Offer should, to the extent permitted by the terms of the security and applicable law, exercise the options or otherwise exercise such rights in order to obtain Alcan Common Shares and deposit those Alcan Common Shares pursuant to the Offer. Any such exercise must be completed sufficiently in advance of the expiration time to assure compliance with the procedures set forth in the section of the Offer entitled “Offer — Manner of Acceptance.” If a holder of stock options to acquire Alcan Common Shares does not exercise such options before the expiration time, such options will remain outstanding in accordance with their terms and conditions, including with respect to term of expiration, vesting (including any terms relating to acceleration of vesting) and exercise prices, except that, pursuant to the subsequent acquisition transaction, in order to treat holders of stock options equitably, each option to acquire Alcan Common Shares is expected to be converted, directly or indirectly, into the right to receive the amount of cash (net of the exercise of option) and the number of Alcoa Common Shares which the holder of such option would have been entitled to receive upon the completion of the subsequent acquisition transaction if such holder had exercised such option immediately prior to the subsequent acquisition transaction.
