        The information set forth in the Offer and Circular, the Notice of Variation and Extension dated July 24, 2006 (the "First Variation"), filed as Exhibit 4.8 and the Notice of Variation and Extension dated August 3, 2006 (the "Second Variation"), filed as Exhibit 4.9, including all schedules, exhibits and annexes thereto, is hereby expressly incorporated by reference in response to all items of information required to be included in, or covered by, this Registration Statement and is supplemented by the information specifically provided herein.

PART II

INFORMATION NOT REQUIRED TO BE DELIVERED
TO OFFEREES OR PURCHASERS

Indemnification

        Under the Canada Business Corporations Act (the "CBCA"), Teck may indemnify a present or former director or officer of Teck or another individual who acts or acted at Teck'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 Teck or the other entity. Teck may not indemnify an individual unless the individual acted honestly and in good faith with a view to the best interests of Teck, 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 Teck'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 Teck 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 and they fulfill the conditions set out above. Teck may advance monies 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 Teck provide that, subject to the limitations contained in the CBCA, Teck shall indemnify a director or officer, a former director or officer, or a person who acts or acted at Teck's request as a director or officer of a body corporate of which Teck is or was a shareholder or creditor (or a person who undertakes or has undertaken any liability on behalf of Teck or any such body corporate) 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 Teck 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 Teck also provide that Teck shall also indemnify such a person in such other circumstances as the CBCA permits or requires.

        The by-laws of Teck provide that Teck may, subject to the limitations contained in the CBCA, purchase and maintain insurance for the benefit of any person referred to in the foregoing paragraph. Teck 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 Teck pursuant to the foregoing provisions, Teck has been informed that in the opinion of the U.S. Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is therefore unenforceable.
