EXPLANATORY NOTE On March 30, 2001, Oil States International, Inc. (the "Company") filed a Registration Statement on Form S-8 (File No. 333-57960) (the "Initial Form S-8") with respect to 3,600,000 shares of common stock, par value $.01 per share, of the Company ("Common Stock") issuable in accordance with the terms of the Oil States International, Inc. 2001 Equity Participation Plan. On July 24, 2002, the Company filed a Registration Statement on Form S-8 (the "Additional Form S-8") registering the offer and sale of an additional 2,000,000 shares of Common Stock issuable in accordance with the terms of the amended and restated Oil States International, Inc. 2001 Equity Participation Plan (as amended and restated, the "First Amended and Restated Plan"), which was approved by the Board of Directors of the Company on February 19, 2002 and by the stockholders at the annual meeting of the Company held on May 15, 2002. On February 16, 2005, the Board of Directors of the Company amended and restated the First Amended and Restated Plan (as amended and restated, the "Second Amended and Restated Plan") to increase the number of shares of Common Stock authorized for issuance thereunder from 5,700,000 to 7,700,000. At the annual meeting of stockholders of the Company held on May 18, 2005, the stockholders of the Company also approved the Second Amended and Restated Plan. Accordingly, this registration statement is being filed to register such 2,000,000 additional shares of Common Stock, and the contents of the Initial Form S-8 and the Additional Form S-8 are incorporated herein by reference except to the extent supplemented, amended or superseded by the information set forth or incorporated by reference herein. In addition, pursuant to General Instruction E to Form S-8, all required opinions and consents are filed as exhibits hereto. 2 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: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information in the 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) (Section 230.424(b) of this chapter) 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 the registration statement or any material change to such information in the registration statement; Provided, however, That paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if the registration statement is on Form S-3 (Section 239.13 of this chapter) or Form S-8 (Section 239.16b of this chapter) or Form F-3 (Section 239.33 of this chapter), and 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 Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, 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. (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 undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) 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 of 1933 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 Securities and Exchange 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. 3 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 Houston, State of Texas, on the 18th day of May, 2006.
