As previously disclosed by Newpark Resources, Inc. (the “Company”) in its Current Report on Form 8-K filed with the Securities and Exchange Commission on April 17, 2006, based on information that had come to its attention, on April 12, 2006, the Audit Committee of the Company’s Board of Directors commissioned an internal investigation regarding potential irregularities involving the processing and payment of invoices by Soloco Texas, LP, one of the Company’s smaller subsidiaries, and other possible violations.

Effective April 12, 2006, and pending completion of the internal investigation, Paul L. Howes, the Company’s Chief Executive Officer has placed on administrative leave the chairman and Chief Executive Officer of Newpark Environmental Water Solutions, LLC, one of the Company’s operating divisions, as well as the Company’s chief financial officer, and an officer of Soloco Texas, LP. No determination of the culpability, if any, of these individuals or any other employees of the Company has been made at this time.

The Company, upon completion of the Audit Committee’s internal investigation, will evaluate the results of the investigation and review with the Audit Committee the effect of the findings on the Company’s consolidated financial statements and system of internal controls. The Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2006 cannot be filed until this process is completed. The Company can not predict with certainty when the investigation will be complete or when it will be able to file the Form 10-Q for the quarterly period ended March 31, 2006 and any restatement of prior historical financial statements, if deemed necessary. However, the Company is hopeful that it will be able to make such filings within 60 days.
