The Company has assumed each outstanding option to purchase shares of common stock of Chiles, par value $.10 per share ("Chiles common stock"), pursuant to the Plan ("Chiles Options") as further explained in Note 2 below. Pursuant to Rule 416 promulgated under the Securities Act of 1933, as amended (the "Securities Act"), there are also being registered such additional shares of Company common stock as may become issuable under the anti-dilution provisions of the Plan or by reason of any dividend, stock-split, recapitalization or any other similar transaction without receipt of consideration that results in an increase in the number of shares of Company common stock issuable pursuant to the assumption of Chiles Options by the Company. (2) On May 14, 2002, the Company, Chore Acquisition, Inc., a Delaware corporation and wholly-owned subsidiary of the Company ("Merger Sub"), and Chiles Offshore Inc., a Delaware corporation ("Chiles"), entered into a Merger Agreement (the "Merger Agreement"). Pursuant to the Merger Agreement, Chiles was merged with and into Merger Sub (the "Merger") on August 7, 2002 (the "Effective Time"), with Merger Sub surviving as a wholly-owned subsidiary of the Company (the "Surviving Company"). As the result of the Merger, each outstanding share of Chiles common stock, other than dissenting shares and shares held by the Company, Merger Sub or Chiles, if any, was converted into the right to receive 0.6575 of a share of Company common stock and $5.25 in cash (the "Merger Consideration"). Also as a result of the Merger, Chiles common stock is no longer issuable upon the exercise of Chiles Options. As of the Effective Time, the Company has assumed Chiles Options originally granted to Plan participants under the Plan. Pursuant to the Merger Agreement, Chiles Options have been converted into options exercisable for such amount of the Merger Consideration as the holders thereof would have received had they exercised their Chiles Options in full immediately prior to the Effective Time. (3) Estimated solely for purpose of calculating the registration fee pursuant to Rule 457(c) and (h) promulgated under the Securities Act, based on the average high and low per share prices of the common stock as reported by the New York Stock Exchange on August 5, 2002. (4) The securities being registered hereby were included in calculation of the registration fee paid in connection with the Company's registration statement no. 333-89998 on Form S-4, filed with the Securities and Exchange Commission (the "Commission") on June 7, 2002.

In accordance with the instructions to Part I of Form S-8, such documents will not be filed with the Commission.

Not applicable. ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL. None. ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS. Section 145 of the Delaware General Corporation Law, or the DGCL, provides that, subject to specific limitations in the case of derivative suits brought by a corporation's stockholders in its name, a corporation may indemnify any individual who is made a party or threatened to be made a party to any third party suit or proceeding on account of being a director, officer, employee or agent of the corporation against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement reasonably incurred by him or her in connection with the action, if the individual: o acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation; and o in the case of a criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. Moreover, to the extent a present or former director or officer is successful in the defense of the action, suit or proceeding, the DGCL requires a corporation to indemnify the individual for reasonable expenses incurred thereby. Article 15 of the Registrant's certificate of incorporation provides, in general, that the Registrant must, to the full extent authorized or permitted by law, indemnify its directors and officers under certain of the circumstances defined in Section 145 of the DGCL, and that no director of the Registrant will be personally liable to the Registrant or its stockholders for monetary damages for any breach of such director's fiduciary duty, with certain exceptions. Article 15 further allows the Registrant to purchase and maintain insurance on behalf of the Registrant's directors, officers, employees or agents and to provide for such indemnification by means of a trust fund, security interest, letter of credit, surety bond, contract and/or similar arrangement. The directors and officers of the Registrant and its subsidiaries are insured (subject to certain exceptions and deductions) against liabilities which they may incur in their capacity as such, including liabilities under the Securities Act, under a liability insurance policy carried by the Registrant. The Registrant has also entered into agreements with its officers and directors which essentially provide that the Registrant will indemnify the officers and directors to the extent set forth in the Registrant's certificate of incorporation and bylaws. Article VII, Section 7 of the Registrant's bylaws provides that the Registrant must indemnify its officers, directors, employees and agents to the full extent permitted by the DGCL. The Merger Agreement provides that for six years from the Effective Time, the Registrant will maintain for the benefit of the current directors and officers of Chiles all existing rights to indemnification. These rights shall be observed by the Registrant to the fullest extent permitted by Delaware law for a period of six years from the Effective Time and the Registrant has agreed to guarantee the performance of these obligations. From the Effective Time until September 18, 2006, the Surviving Company shall maintain in effect, for the benefit of the current directors and officers of Chiles with respect to acts or omissions occurring prior to the Effective Time, the existing policy of directors' and officers' liability insurance maintained by Chiles as of the date of the Merger Agreement in the form disclosed by Chiles to the Registrant prior to the date of the Merger Agreement; provided that (a) the Surviving Company may substitute for such existing policy a policy or policies of comparable coverage and (b) the Surviving Company shall not be required to pay annual premiums for such existing policy (or for any substitute policies) in excess of $200,000 in the aggregate. In the event any future annual premiums for such existing policy (or any substitute policies) exceed $200,000 in the aggregate, the Surviving Company shall be entitled to reduce the amount of coverage of the existing policy (or any substitute policies) to the amount of coverage that can be obtained for an aggregate annual premium of $200,000.

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: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) 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 Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement; provided, however, that the undertakings set forth in paragraphs (a)(1)(i) and (a)(1)(ii) 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 or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement; (2) 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; and (3) 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 further 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 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this 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 Securities 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 Securities 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 duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Dallas, State of Texas, on August 7, 2002.
