Issuer Delisting; Notice of Application To Withdraw From Listing and Registration; (Nexen Inc. (Formerly Canadian Occidental Petroleum Ltd.), Common Shares, No Par Value) File No. 1-06702

Nexen Inc. (formerly Canadian Occidental Petroleum Ltd.), which is organized under the laws of Canada (“Company”), has filed an application with the Securities and Exchange Commission (“Commission”), pursuant to Section 12(d) of the Securities Exchange Act of 1934 (“Act”) and Rule 12d2-2(d) thereunder, to withdraw its Common Shares, no par value (“Security”), from listing and registration on the American Stock Exchange (“Amex”).

The Company has obtained a new listing for its Security on the New York Stock Exchange (“NYSE”). Trading in the Security commenced on the NYSE, and was concurrently suspended on the Amex, at the opening of business on November 14, 2000. Having obtained the new NYSE listing, the Company has determined to withdraw the Security from listing and registration on the Amex for the following reasons: (i) To avoid the additional direct and indirect costs of maintaining such listing; (ii) to prevent potential fragmentation of the market for its Security; and (iii) the Company no longer feels that the continued listing of its Security on the Amex is in its best interests.

The Company's application relates solely to the withdrawal of the Security from listing and registration on the Amex and shall have no effect upon either the Security's continued listing and registration on the NYSE or the Company's continuing obligation under Sections 12(b) and 13 of the Act to file certain reports with the Commission.

Any interested person may, on or before December 7, 2000, submit by letter to the Secretary of the Securities and Exchange Commission, 450 Fifth Street, NW., Washington, DC 20549-0609, facts bearing upon whether the application has been made in accordance with the rules of the Amex and what terms, if any, should be imposed by the Commission for the protection of investors. The Commission, based on the information submitted to it, will issue an order granting the application after the date mentioned above, unless the Commission determines to order a hearing on the matter.
