Item 5. Interests of Named Experts and Counsel. Legal matters in connection with the issuance and sale of the securities offered hereby will be passed upon by Samuel H. Gillespie, Senior Vice President, Chief Legal Officer and General 2 Counsel of the Company. As of June 1, 2004, Mr. Gillespie owned beneficially 14,821 shares of Common Stock. He also held an option to purchase 16,360 shares of common stock at the price of $36.869 which expires on February 10, 2014. In addition, Mr. Gillespie held 8,389 performance share units, which could be paid out in up to 16,778 shares of common stock on December 31, 2006, based upon the extent of the Company's achievement of performance goals determined within the first 90 days of the award period that began January 1, 2004. Item 6. Indemnification of Directors and Officers. Section 145 of the Delaware General Corporation Law authorizes Unocal to indemnify directors and officers in certain circumstances against liabilities, including expenses, incurred while acting in such capacities; provided, generally, that any such indemnified director or officer acted in good faith and in a manner he or she reasonably believed to be in the best interests of the corporation and, in the case of a criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The Bylaws of Unocal provide for the indemnification of directors and officers to the maximum extent permitted by the Delaware General Corporation Law. In addition, Unocal has provided in its Restated Certificate of Incorporation that it shall eliminate the personal liability of its directors to the fullest extent permitted by the Delaware General Corporation Law and Unocal has entered into indemnification agreements with each of its directors and officers providing for additional indemnification. Unocal has policies of directors' and officers' liability insurance which insure directors and officers against the costs of defense, settlement or payment of a judgment under certain circumstances. Item 8. Exhibits. The Exhibit Index lists the exhibits that are filed as part of this registration statement. Item 9. Undertakings. a. The undersigned Registrant hereby undertakes: 1. To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: a. To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the "Securities Act"); b. To reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to 3 Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the calculation of Registration Fee table in the effective registration statement; c. To include any material information with respect to the plan distribution not previously disclosed in this statement or any material change to such information in this registration statement; 2. Provided, however, that the undertakings set forth in paragraphs (a) and (b) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Act of 1934 (the "Exchange Act") that are incorporated by reference in this registration statement. 3. That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 4. To remove from registration by means of a post-effective amendment, any of the securities being registered which remain unsold at the termination of the offering. b. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. c. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has 4 duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of El Segundo, State of California, on June 7, 2004.
