INFORMATION REQUIRED TO BE DELIVERED TO OFFEREES OR PURCHASERS

Item 1. Home Jurisdiction Document.

        This Post Effective Amendment No. 1 amends and supplements the Registration Statement on Form F-8 filed with the U.S. Securities and Exchange Commission on September 8, 2006 (the "Initial Registration Statement" and as amended by this Post Effective Amendment No. 1, the "Registration Statement") by Yamana Gold Inc. ("Yamana" or the "Registrant").

        The Registration Statement relates to the offer (the "Offer") by Yamana to purchase all of the outstanding common shares of Viceroy Exploration Ltd. ("Viceroy"), which includes common shares that may become outstanding after the date of the Offer but before the Expiry Time of the Offer upon conversion, exchange or exercise of options or other securities of Viceroy that are convertible or exchangeable or exercisable for common shares. Under the terms of the Offer, Viceroy shareholders will receive 0.97 common shares of Yamana for each Viceroy common share tendered. The Offer is open for acceptance until midnight (24h00) (Toronto time) on October 13, 2006.

        The Offer is subject to the terms and conditions set forth in the Offer and Circular dated September 6, 2006 and the related Letter of Transmittal, copies of which were filed as Part I of the Initial Registration Statement. Capitalized terms used herein and not defined herein have the respective meaning assigned to such terms in the Offer and Circular.

        The Offer and Circular is amended and supplemented as follows:

        Notice to Shareholders in the United States (page iii of the Offer and Circular) is hereby amended by adding the following legend as the penultimate paragraph thereof:

        "Shareholders in the United States should be aware that the Offeror or its affiliates, directly or indirectly, may bid for or make purchases of Viceroy Shares or of Viceroy's related securities during the period of the Offer, as permitted by applicable laws or regulations of Canada or its provinces or territories."

        Letter of Transmittal: The Letter of Transmittal relating to the Offer is hereby amended by deleting the last paragraph of Section 12 of the Instructions thereto on page 14 thereof.

PART II

INFORMATION NOT REQUIRED TO BE DELIVERED TO OFFEREES OR PURCHASERS

INDEMNIFICATION

        Under the CANADA BUSINESS CORPORATIONS ACT (the "CBCA"), Yamana Gold Inc. (the "Registrant") may indemnify a present or former director or officer of the Registrant or another individual who acts or acted at the Registrant's request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of that association with the Registrant or other entity. The Registrant may not indemnify an individual unless the individual acted honestly and in good faith with a view to the best interests of the Registrant, or, as the case may be, to the best interests of the other entity for which the individual acted as a director or officer or in a similar capacity at the Registrant's request and in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, the individual had reasonable grounds for believing that the conduct was lawful. The indemnification may be made in connection with a derivative action only with court approval. The aforementioned individuals are entitled to indemnification from the Registrant as a matter of right if they were not judged by the court or other competent authority to have committed any fault or omitted to do anything that the individual ought to have done. The Registrant may advance moneys to the individual for the costs, charges and expenses of a proceeding; however, the individual shall repay the moneys if the individual does not fulfill the conditions set out above.

        The by-laws of the Registrant provide that, subject to the limitations contained in the CBCA, the Registrant shall indemnify a director or officer, a former director or officer, or a person who acts or acted at the Registrant's request as a director or officer of a body corporate of which the Registrant is or was a shareholder or creditor, and his heirs and legal representatives against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by him in respect of any civil, criminal or administrative action or proceeding to which he was made a party by reason of being or having been a director or officer of the corporation or such body corporate, if he acted honestly and in good faith with a view to the best interests of the corporation, and in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, he had reasonable grounds for believing that his conduct was lawful.

        The by-laws of the Registrant provide that the Registrant may, subject to the limitations contained in the CBCA, purchase, maintain, or participate in insurance for the benefit of any director, officer, or certain other persons, as such against any liability incurred by him in his capacity as a director or officer of the Registrant or as a director or officer of any body corporate where he acts or acted in that capacity at the Registrant's request. The Registrant has purchased third party director and officer liability insurance.

        Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is therefore unenforceable.
