The foregoing discussion contains 'forward-looking statements' within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Act of 1934, as amended. There are risks and uncertainties that could cause future events and results to differ materially from those anticipated by management in the forward-looking statements included in this press release. For further information regarding these and other factors, risks and uncertainties affecting Newpark, reference is made to the risk factors set forth in the Prospectus included in Newpark's Registration Statement on Form S-3 filed on May 8, 2002 (File No. 333-87840), and to the section entitled "Forward Looking Statements" on page 17 of that Prospectus. In particular, as described on page 9 of that Prospectus, any material decline in the level of oil and gas exploration and production activity could result in fewer opportunities being available for the service industry in general and Newpark in particular, and may adversely affect the demand for our services. In addition, as described on page 13 of that Prospectus, and rescission or relaxation of governmental regulations, including in the discharge regulations recently implemented, could reduce the demand for Newpark's services and reduce Newpark's revenues and income. You are strongly urged to review these sections for a more detailed discussion of these risks and uncertainties.
