Form 10-K for the year ended December 31, 2002. The Newpark Resources, Inc. Form 10-K for the year ended December 31, 2003, was not available for comparison. Mr. Bryan, a director of the Company, resigned as an Executive Vice President of Newpark in December 2003. His position with Newpark was not the result of his position on the Company’s Board of Directors. He received no compensation from Newpark based on the business relationship between the Company and Newpark. He did not hold 5% or more of any outstanding securities of Newpark Resources, Inc. Mr. Bryan, however, has voluntarily elected to resign his position with Newpark Drilling Fluids, Inc. in light of the adoption of changes in the rules for listed companies by the NYSE that would have required that Mr. Bryan be considered a non-independent director of the Company. The Board has determined that Mr. Bryan is an independent director and that his former position with Newpark does not cause a conflict of interest.
