ITEM 2.06 MATERIAL IMPAIRMENTS. SEE THE DISCUSSION UNDER ITEM 4.02 BELOW. ITEM 4.02 NON-RELIANCE ON PREVIOUSLY ISSUED FINANCIAL STATEMENTS OR A RELATED AUDIT REPORT OR COMPLETED INTERIM REVIEW. As disclosed in the Current Report on Form 8-K filed by Newpark Resources, Inc. with the Securities and Exchange Commission on April 17, 2006, the Audit Committee of the Board of Directors commissioned an internal investigation, led by independent counsel, regarding potential irregularities involving the processing and payment of invoices by Soloco Texas, LP, ("Soloco") one of Newpark's smaller subsidiaries, and other transactions. Based on evidence obtained during the course of the investigation, the Audit Committee has determined that certain transactions between Soloco and a supplier with which Soloco had a significant commercial relationship were not properly accounted for, and that certain payments of invoices by Soloco to such supplier were improperly paid. In addition, the Audit Committee concluded that certain intangible assets that had been recorded in connection with a series of license arrangements and certain other transactions that had been entered into between Soloco and the same supplier during the 1990s and through 2002 had either become impaired or had not received proper accounting treatment at the time the intangibles had been recorded. After analyzing the pertinent quantitative and qualitative factors surrounding these transactions, on June 26, 2006, the Audit Committee of the Board of Directors of Newpark Resources, Inc., in consultation with and upon the recommendation of Newpark's management, and after consultation with the Company's independent registered public accounting firm, concluded that its previously issued audited financial statements for the fiscal years ended December 31, 2001 through 2005, and its interim unaudited financial statements for the fiscal quarters within 2004 and 2005, should be restated. Accordingly, these financial statements and the independent registered public accounting firm's reports related to the financial statements contained in Newpark's prior filings with the Securities and Exchange Commission should no longer be relied upon. Newpark will amend its Annual Report on Form 10-K for the year ended December 31, 2005 and its quarterly reports on Form 10-Q for the periods within that year to make the necessary adjustments to its financial statements. As disclosed in Newpark's Current Report on Form 8-K filed with the Securities and Exchange Commission on May 9, 2006, Newpark had expected the results of the investigation to conclude that there would be charges related to asset impairments and other adjustments not exceeding $10 million on a pretax basis, subject to possible recovery from third parties. Excluding the effects of improper granting of stock options on previously issued financial statements noted below under the caption Item 8.01 Other Events, which remains the subject of an investigation not yet concluded, the Audit Committee presently expects the total impact of the restatement of the financial statements for the periods referenced above to not be in excess of the original $10 million estimate, with a substantial portion of the charges, all of which are non-cash charges, being attributed to the fiscal years ended December 31, 2002 and 2003, and earlier periods. While the initial investigation related to matters at Soloco is now complete, and the investigation of improper option granting practices noted below is nearing completion, Newpark cannot predict with certainty when it will be able to file its amended reports or its Quarterly Report on Form 10-Q for the quarter ended March 31, 2006. However, Newpark will make the necessary filings as soon as practical. 2

ITEM 8.01 OTHER EVENTS. During the course of the internal investigation, the Audit Committee also requested a review of the Company's past practices regarding the awarding of stock options, which was deemed an appropriate line of inquiry of the originally commissioned investigation given the recent focus by the Securities and Exchange Commission and others on stock option grant practices by publicly traded companies. This review is ongoing, but the preliminary findings of the investigation are that certain stock options granted prior to June 2003 were dated on a date other than the date their issuance was approved, and the exercise price of such options was determined by reference to sales prices of the Company's common stock other than the fair market vale of the stock as of the date of grant, in contravention of the Company's stock option plan. For periods thereafter, all stock options granted by the Company appear to have conformed to the requirements of the plan. While the investigation of the improper option granting practices is not yet complete and the related financial statement impact has not been fully evaluated, preliminary estimates indicate that the reduction in pretax income for the fiscal years 2003 through 2005 is not expected to exceed $2 million in the aggregate, depending on final determination of the actual date of grant. The reduction in pre-tax income for the referenced periods, however, is not expected to reduce total stockholders' equity. The Audit Committee and management have discussed the matters disclosed under Items 2.06, 4.02 and 8.01 with Newpark's independent registered public accounting firm. ITEM 5.02 DEPARTURE OF DIRECTORS OR PRINCIPAL OFFICERS; ELECTION OF DIRECTORS; APPOINTMENT OF PRINCIPAL OFFICERS. The Company's chief executive officer, with approval of the Board of Directors, decided to terminate the employment of Mr. James Cole, the Company's former chief executive officer and current chairman of Newpark Environmental Water Solutions and Mr. Matt Hardey, the Company's chief financial officer. Mr. Cole and Mr. Hardey had previously been placed on administrative leave by the Board of Directors at the time of the commencement of the previously announced internal investigation commissioned by the Audit Committee. In the case of Messrs. Cole and Hardey, the Board found, based on the findings of the internal investigation, that cause existed for their termination given their responsibility for many of the actions uncovered by the investigation that have led to the Company's determination that a restatement of prior period financial statements is required. Mr. Cole previously elected voluntarily not to stand for re-election as a member of Newpark's board of directors at the next annual meeting of stockholders. A copy of the press release regarding the matters disclosed herein is attached to this Form 8-K as Exhibit 99.1 and is incorporated herein by reference. 3

                NEWPARK UPDATES STATUS OF INTERNAL INVESTIGATION

    METAIRIE, La., June 29 /PRNewswire-FirstCall/ -- Newpark Resources, Inc.
(NYSE: NR) today announced that the Audit Committee of the Board of Directors
of Newpark Resources, Inc. has completed its initial internal investigation
which began on April 17, 2006.  As a result of the findings of the
investigation, the Company will restate its financial statements for the
fiscal years ended December 31, 2001 through 2005, and for the fiscal quarters
within 2004 and 2005.

    Excluding the impact of improper option granting practices on previously
issued financial statements discussed below, which has not yet been completely
determined, the aggregate impact of the error corrections over the restatement
periods will reduce previously reported pretax income by less than
$10 million, the maximum amount previously disclosed by the Company.  All of
the charges to be recorded as a result of the restatements are non-cash
charges.  A substantial portion of the charges will be attributed to the
fiscal years ended December 31, 2002 and 2003, and earlier periods.

    As previously announced in the Company's press release dated
April 17, 2006, the Audit Committee of the Board of Directors had commissioned
an internal investigation, with the assistance of independent counsel,
regarding potential irregularities involving the processing and payment of
invoices by Soloco Texas, LP, (Soloco) one of Newpark's smaller subsidiaries,
and other transactions.  The investigation concluded that certain transactions
were not properly accounted for, resulting in the restatement.  The Company
analyzed all the pertinent quantitative and qualitative factors surrounding
these transactions in making its determination regarding the restatement.

    During the course of the internal investigation, the Audit Committee also
requested a review of the Company's past practices regarding the awarding of
stock options, which was deemed an appropriate line of inquiry of the
originally commissioned investigation given the recent focus by the Securities
and Exchange Commission and others on stock option grant practices by publicly
traded companies.  This review is ongoing, but the preliminary findings of the
investigation are that a portion of the stock options granted prior to
June 2003 were dated on a date other than the date their issuance was
approved, and the exercise price of such options was determined in advance of
their approval by the appropriate board committee, all in contravention of the
Company's stock option plan.  For periods thereafter, all stock options
granted by the Company appear to have conformed to the requirements of the
plan.

    While the investigation of the improper option granting practices is not
yet complete and the related financial statement impact has not been fully
evaluated, preliminary estimates indicate that the reduction in pretax income
for the fiscal years 2003 through 2005 is expected not to exceed $2 million in
the aggregate, depending on final determination of the actual date of grant.
The adjustments to pretax income related to the improper option granting
practices is not expected to have any impact on total stockholders' equity.

    While the initial investigation related to matters at Soloco is now
complete and the investigation of improper option granting practices is
nearing completion, Newpark cannot predict with certainty when it will be able
to file its amended reports or its Quarterly Report on Form 10-Q for the
quarter ended March 31, 2006.  However, Newpark will make the necessary
filings as soon as practical.

    The Company also announced that Newpark's chief executive officer, with
approval from the Board of Directors, has terminated the employment of
Mr. James Cole, the Company's former chief executive officer and current
Chairman of Newpark Environmental Water Solutions and Mr. Matt Hardey, the
Company's Chief Financial Officer.  Mr. Cole and Mr. Hardey had previously
been placed on administrative leave by the Board of Directors at the time of
the commencement of the previously announced internal investigation
commissioned by the Audit Committee.  In the case of Messrs. Cole and Hardey,
the Board found, based on the findings of the internal investigation, that
cause existed for their termination given their responsibility for many of the
actions uncovered by the investigation that have led to the Company's
determination that a restatement of prior period financial statements is
required.
