AGREEMENT AND PLAN OF MERGER ---------------------------- AGREEMENT AND PLAN OF MERGER (the "Agreement"), dated as of June 24, 1999, by and among Tuboscope Inc., a Delaware corporation ("Tuboscope"), and Newpark Resources, Inc., a Delaware corporation ("Newpark"). WHEREAS, the Boards of Directors of Tuboscope and Newpark deem it advisable and in the best interests of each corporation and its respective stockholders that Tuboscope and Newpark combine in order to advance the long- term business interests of Tuboscope and Newpark; WHEREAS, the combination of Tuboscope and Newpark shall be effected by the terms of this Agreement through a merger in which the stockholders of Newpark will become stockholders of Tuboscope (the "Merger"); and WHEREAS, for Federal income tax purposes, it is intended that the Merger shall qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"). NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below, the parties agree as follows: ARTICLE I. THE MERGER Section 1.01. The Merger. Upon the terms and subject to the ---------- conditions of this Agreement, in accordance with the Delaware General Corporation Law (the "DGCL"), at the Effective Time (as defined in Section 1.02 hereof), Newpark shall merge with and into Tuboscope. Section 1.02. Effective Time of the Merger. Subject to the ---------------------------- provisions of this Agreement, a certificate of merger with respect to the Merger in such form as is required by the relevant provisions of the DGCL (the "Certificate of Merger") shall be duly executed by Tuboscope and thereafter delivered to the Secretary of State of the State of Delaware for filing, as early as practicable on the Closing Date (as defined in Section 1.03). The Merger shall become effective at 4:00 p.m., C.S.T., on the date of filing of the Certificate of Merger with the Secretary of State of the State of Delaware or at such other time as specified herein (the "Effective Time").

Section 1.03. Closing. The closing of the Merger (the "Closing") ------- will take place at 10:00 a.m., C.S.T., on a date to be specified by Tuboscope and Newpark, which shall be no later than the second business day after satisfaction of the latest to occur of the conditions set forth in Sections 7.01, 7.02(b) (other than the delivery of the officers' certificate referred to therein) and 7.03(b) (other than the delivery of the officers' certificate referred to therein) (provided that the other closing conditions set forth in Article VII have been met or waived as provided in Article VII at or prior to the Closing) (the "Closing Date"), at the corporate offices of Tuboscope at the address indicated in Section 9.02 unless another date, place or time is agreed to in writing by Tuboscope and Newpark. Section 1.04. Effects of the Merger. As a result of the Merger, the --------------------- separate corporation existence of Newpark shall cease and Tuboscope shall continue as the surviving corporation. Section 1.05. Directors. At or prior to the Effective Time, --------- Tuboscope shall (i) set the number of the members of the Board of Directors of Tuboscope at ten and (ii) take such action as may be necessary to cause the ten individuals named on Schedule I attached hereto to be the members of the Board of Directors of Tuboscope as of the Effective Time. ARTICLE II. CONVERSION OF SECURITIES Section 2.01. Conversion of Capital Stock. As of the Effective Time, --------------------------- by virtue of the Merger and without any action on the part of the holder of any shares of capital stock of Newpark or Tuboscope: (a) Cancellation of Treasury Stock and Tuboscope-Owned Stock. -------------------------------------------------------- All shares of Common Stock of Newpark ("Newpark Common Stock") that are owned by Newpark as treasury stock and any shares of Newpark Common Stock owned by Tuboscope or any Subsidiary (as defined in Section 3.01) of Tuboscope shall be canceled and retired and shall cease to exist and no stock of Tuboscope or other consideration shall be delivered in exchange therefor. All shares of Common Stock, par value $.01 per share, of Tuboscope ("Tuboscope Common Stock") owned by Newpark shall be canceled and retired and shall cease to exist and no stock of Tuboscope or other consideration shall be delivered in exchange therefor. (b) Exchange Ratio for Newpark Common Stock. Subject to Section 2.02, each issued and outstanding share of Newpark Common Stock shall be converted into the right to receive .65 share (the "Exchange Ratio") of Tuboscope Common Stock. All such shares of Newpark Common Stock, when so converted, shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares shall cease to have any rights with respect thereto, except the right to receive the shares of Tuboscope Common Stock and any cash in lieu of fractional shares of Tuboscope Common Stock to be issued or paid in consideration therefor upon the surrender of such certificate in accordance with Section 2.02, without interest. Notwithstanding the foregoing, if between the date of this Agreement and the Effective Time the outstanding 2

shares of Tuboscope Common Stock shall have been changed into a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares, then the Exchange Ratio contemplated shall be correspondingly adjusted to reflect such stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares. (c) Conversion of Newpark Preferred Stock. Subject to Section 2.02, ------------------------------------- the issued and outstanding shares of Series A Cumulative Perpetual Preferred Stock, par value $.01 per share, of Newpark (the "Newpark Series A Preferred Stock") shall be converted into and represent the right to receive 965,347 shares of Tuboscope Common Stock plus, if applicable, a number of shares of Tuboscope Common Stock equal to the product of (i) the Exchange Ratio and (ii) the number of shares of Newpark Common Stock which would be issuable as a dividend for accrued but unpaid dividends with respect to the Newpark Series A Preferred Stock as of the Effective Time, calculated based on the average Market Price (as defined in the Certificate of Designation of the Newpark Series A Preferred Stock) of the Newpark Common Stock for the five trading days ending the day before the Effective Time (collectively, the "Preferred Merger Consideration"). As of the Effective Time, all such shares of Newpark Series A Preferred Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate which, prior to the Effective Time, represented any such shares of Newpark Series A Preferred Stock shall cease to have any rights with respect thereto, except the right to receive the Preferred Merger Consideration and any cash in lieu of fractional shares of Tuboscope Common Stock to be issued or paid in consideration therefor upon surrender of such certificate in accordance with Section 2.02, without interest. Notwithstanding the foregoing, if between the date of this Agreement and the Effective Time the outstanding shares of Tuboscope Common Stock shall have been changed into a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares, then the Exchange Ratio contemplated shall be correspondingly adjusted to reflect such stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares. Section 2.02. Exchange of Certificates. The procedures for ------------------------ exchanging outstanding shares of Newpark Common Stock for Tuboscope Common Stock pursuant to the Merger are as follows: (a) Exchange Agent. As of the Effective Time, Tuboscope shall -------------- deposit with a bank or trust company designated by Tuboscope and Newpark (the "Exchange Agent"), for the benefit of the holders of shares of Newpark Common Stock and Newpark Series A Preferred Stock, for exchange in accordance with this Section 2.02, through the Exchange Agent, certificates representing the shares of Tuboscope Common Stock and an estimated amount of cash in lieu of fractional shares (such shares of Tuboscope Common Stock, together with any dividends or distributions with respect thereto, and cash in lieu of fractional shares being hereinafter referred to as the "Exchange Fund") issuable pursuant to Section 2.01 in exchange for outstanding shares of Newpark Common Stock and Newpark Series A Preferred Stock. 3

(b) Exchange Procedures. As soon as reasonably practicable ------------------- after the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Newpark Common Stock or Newpark Series A Preferred Stock (the "Certificates") whose shares were converted pursuant to Section 2.01 into the right to receive shares of Tuboscope Common Stock (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Tuboscope and Newpark may reasonably specify) and (ii) instructions for effecting the surrender of the Certificates in exchange for certificates representing shares of Tuboscope Common Stock (plus cash in lieu of fractional shares, if any, of Tuboscope Common Stock as provided below). Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Tuboscope, together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Tuboscope Common Stock and cash in lieu of fractional shares which such holder has the right to receive pursuant to the provisions of this Article II, and the Certificate so surrendered shall immediately be canceled. In the event of a transfer of ownership of Newpark Common Stock or Newpark Series A Preferred Stock which is not registered in the transfer records of Newpark, a certificate representing the proper number of shares of Tuboscope Common Stock may be issued to a transferee if the Certificate representing such Newpark Common Stock or Newpark Series A Preferred Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 2.02, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the certificate representing shares of Tuboscope Common Stock and cash in lieu of any fractional shares of Tuboscope Common Stock as contemplated by this Section 2.02. (c) Distributions with Respect to Unexchanged Shares. No ------------------------------------------------ dividends or other distributions declared or made after the Effective Time with respect to Tuboscope Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Tuboscope Common Stock represented thereby and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to subsection (e) below until the holder of record of such Certificate shall surrender such Certificate. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be paid to the record holder of the certificates representing whole shares of Tuboscope Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of a fractional share of Tuboscope Common Stock to which such holder is entitled pursuant to subsection (e) below and the amount of dividends or other distributions with a record date after the Effective Time previously paid with respect to such whole shares of Tuboscope Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of Tuboscope Common Stock. 4

(d) No Further Ownership Rights in Newpark Common Stock or ------------------------------------------------------ Newpark Series A Preferred Stock. All shares of Tuboscope Common Stock issued - -------------------------------- upon the surrender for exchange of Certificates in accordance with the terms hereof (including any cash paid pursuant to subsection (c) or (e) of this Section 2.02) shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Newpark Common Stock or Newpark Series A Preferred Stock. Notwithstanding the foregoing, Tuboscope is obligated to pay any dividends or make any other distributions with a record date prior to the Effective Time which may have been declared or made by Newpark on shares of Newpark Common Stock or Newpark Series A Preferred Stock in accordance with the terms of this Agreement (to the extent permitted under Section 5.01) prior to the date hereof and which remain unpaid at the Effective Time. From and after the Effective Time, there shall be no further registration of transfers on the stock transfer books of Tuboscope of the shares of Newpark Common Stock or Newpark Series A Preferred Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to Tuboscope for any reason, they shall be canceled and exchanged as provided in this Section 2.02. (e) No Fractional Shares. No certificate or scrip representing -------------------- fractional shares of Tuboscope Common Stock shall be issued upon the surrender for exchange of Certificates, and such fractional share interests will not entitle the owner thereof to vote or to any other rights of a stockholder of Tuboscope. Notwithstanding any other provision of this Agreement, each holder of shares of Newpark Common Stock or Newpark Series A Preferred Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Tuboscope Common Stock (after taking into account all Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of Tuboscope Common Stock multiplied by the average of the last reported sales prices of Tuboscope Common Stock, as reported on the New York Stock Exchange ("NYSE"), on each of the ten trading days immediately preceding the date of the Effective Time. (f) Termination of Exchange Fund. Any portion of the Exchange ---------------------------- Fund which remains undistributed to the stockholders of Newpark for 180 days after the Effective Time shall be delivered to Tuboscope, upon demand, and any stockholders of Newpark who have not previously complied with this Section 2.02 shall thereafter look only to Tuboscope for payment of their claim for Tuboscope Common Stock, any cash in lieu of fractional shares of Tuboscope Common Stock and any dividends or distributions with respect to Tuboscope Common Stock. (g) No Liability. Neither Tuboscope nor Newpark shall be liable ------------ to any holder of shares of Newpark Common Stock, Newpark Series A Preferred Stock or Tuboscope Common Stock, as the case may be, for such shares (or dividends or distributions with respect thereto) delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. (h) Withholding Rights. Tuboscope shall be entitled to deduct ------------------ and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of 5

shares of Newpark Common Stock or Newpark Series A Preferred Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by Tuboscope, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Newpark Common Stock or Newpark Series A Preferred Stock in respect of which such deduction and withholding was made by Tuboscope. (i) Lost Certificates. If any Certificate shall have been lost, ----------------- stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Tuboscope, the posting by such person of a bond in such reasonable amount as Tuboscope may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the shares of Tuboscope Common Stock and any cash in lieu of fractional shares, and unpaid dividends and distributions on shares of Tuboscope Common Stock deliverable in respect thereof pursuant to this Agreement. ARTICLE III. REPRESENTATIONS AND WARRANTIES OF NEWPARK Newpark represents and warrants to Tuboscope that the statements contained in this Article III are true and correct except as set forth herein and in the disclosure schedule delivered by Newpark to Tuboscope on or before the date of this Agreement (the "Newpark Disclosure Schedule"). The Newpark Disclosure Schedule shall be arranged in paragraphs corresponding to the numbered and lettered paragraphs contained in this Article III and the disclosure in any paragraph shall qualify other paragraphs in this Article III only to the extent that it is reasonably apparent from a reading of such disclosure that it also qualifies or applies to such other paragraphs. Section 3.01. Organization of Newpark. Each of Newpark and its ----------------------- Subsidiaries (as defined below) is a corporation or unincorporated entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization, has all requisite corporate or entity power to own, lease and operate its property and to carry on its business as now being conducted and as proposed to be conducted, and is duly qualified to do business and is in good standing as a foreign corporation or organization in each jurisdiction in which the failure to be so qualified would have a material adverse effect on the business, properties, financial condition, or results of operations of Newpark and its Subsidiaries, taken as a whole (a "Newpark Material Adverse Effect"). Except as set forth in the Newpark SEC Reports (as defined in Section 3.04) filed prior to the date hereof, neither Newpark nor any of its Subsidiaries directly or indirectly owns any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for, any corporation, partnership, joint venture or other business association or entity, excluding securities in any publicly traded company held for investment by Newpark or its Subsidiaries and comprising less than five percent (5%) of the outstanding stock of such company. As used in this Agreement, the word "Subsidiary" means, with respect to any party, any corporation or other organization, whether incorporated or unincorporated, of which (i) such party or any other Subsidiary of such party is a general partner 6

All of the outstanding shares of capital stock of each of Newpark's Subsidiaries are duly authorized, validly issued, fully paid and nonassessable and all such shares (other than directors' qualifying shares in the case of foreign Subsidiaries) are owned by Newpark or another Subsidiary free and clear of all security interests, liens, claims, pledges, agreements, limitations in Newpark's voting rights, charges or other encumbrances of any nature.

Newpark or any of its Subsidiaries or obligating Newpark or any of its Subsidiaries to grant, extend, accelerate the vesting of or enter into any such option, warrant, equity security, call, right, commitment or agreement. To the best knowledge of Newpark, there are no voting trusts, proxies or other voting agreements or understandings with respect to the shares of capital stock of Newpark.

The audited balance sheet of Newpark as of December 31, 1998 is referred to herein as the "Newpark Balance Sheet." Section 3.05. No Undisclosed Liabilities. Except as disclosed in the -------------------------- Newpark SEC Reports filed prior to the date hereof, and except for normal or recurring liabilities incurred since December 31, 1998 in the ordinary course of business consistent with past practices, Newpark and its Subsidiaries do not have any liabilities, either accrued, contingent or otherwise (whether or not required to be reflected in financial statements in accordance with generally accepted accounting principles), and whether due or to become due, which individually or in the aggregate are reasonably likely to have a Newpark Material Adverse Effect. Section 3.06. Absence of Certain Changes or Events. Except as ------------------------------------ disclosed in the Newpark SEC Reports filed prior to the date hereof, since the date of the Newpark Balance 9

Sheet, Newpark and its Subsidiaries have conducted their businesses only in the ordinary course and in a manner consistent with past practice and, since such date, there has not been (i) any material adverse change in the financial condition, results of operations, business or properties (a "Material Adverse Change") of Newpark and its Subsidiaries, taken as a whole (other than changes that are the effect or result of economic factors affecting the oil and gas exploration and production industry or the economy as a whole) or any development or combination of developments of which the management of Newpark is aware that, individually or in the aggregate, has had, or is reasonably likely to have, a Newpark Material Adverse Effect (other than developments that are the effect or result of actions to be taken by Tuboscope or economic factors affecting the oil and gas exploration and production industry or the economy as a whole); (ii) any damage, destruction or loss (whether or not covered by insurance) with respect to Newpark or any of its Subsidiaries having a Newpark Material Adverse Effect; (iii) any material change by Newpark in its accounting methods, principles or practices to which Tuboscope has not previously consented in writing; (iv) any revaluation by Newpark of any of its assets having a Newpark Material Adverse Effect; or (v) any other action or event that would have required the consent of Tuboscope pursuant to Section 5.01 of this Agreement had such action or event occurred after the date of this Agreement and that, individually or in the aggregate, has had or is reasonably likely to have a Newpark Material Adverse Effect. Section 3.07. Taxes. ----- (a) For the purposes of this Agreement, a (i) "Tax" or, collectively, "Taxes," means any and all federal, state, local or foreign gross receipts, income, profits, sales, use, value added, ad valorem, transfer, gains, franchise, withholding, payroll, recapture, employment, excise, unemployment, social security, license, occupation, business organization, stamp, environmental, property, severance, premium, custom duties, capital stock, disability, registration, alternative or add-on minimum, estimated, or other tax of any kind whatsoever, including any interest, penalty or addition thereto, whether disputed or not, and any obligations under any agreements or arrangements with any other person with respect to such amounts and any liability for such amounts of a predecessor entity, and (ii) "Tax Return" shall mean any return, declaration, report, claim for refund, or information return or statement relating to Taxes, including any schedule or attachment thereto, and including any amendment thereof.

All such Tax Returns are complete and correct in all respects, except for any such omissions or errors which are not reasonably likely, individually or in the aggregate, to have a Newpark Material Adverse Effect. Newpark and each of its Subsidiaries has paid (or Newpark has paid on its Subsidiaries' behalf) all Taxes shown as due on such Tax Returns, and Newpark's most recent consolidated financial statements reflect an adequate reserve for all Taxes payable by Newpark and its Subsidiaries for all taxable periods and portions thereof through the date of such financial statements, except to the extent that any such Taxes are not reasonably likely, individually or in the aggregate, to have a Newpark Material Adverse Effect.

No deficiencies for any Taxes (other than those which are not reasonably likely, individually or in the aggregate, to have a Newpark Material Adverse Effect) have been proposed, asserted or assessed against Newpark or any of its Subsidiaries that have not been fully paid or adequately provided for in the appropriate financial statements of Newpark and its Subsidiaries, no requests for waivers of the time to assess any Taxes are pending, and none of Newpark or any of its Subsidiaries have waived any statute of limitations in respect of Taxes or agreed to any extension of time with respect to a Tax assessment or deficiency. Newpark and each of its Subsidiaries have withheld or collected and paid over to the appropriate governmental authorities (or are properly holding for such payment) all Taxes required by law to be withheld or collected, except for amounts which are not reasonably likely, individually or in the aggregate, to have a Newpark Material Adverse Effect. Neither Newpark nor any of its Subsidiaries has made an election under Section 341(f) of the Code, except for any such election which shall not have a Newpark Material Adverse Effect. There are no liens for Taxes upon the assets of Newpark or any of its Subsidiaries (other than liens for Taxes that are not yet due or that are being contested in good faith by appropriate proceedings), except for liens which are not reasonably likely, individually or in the aggregate, to have a Newpark Material Adverse Effect.

Properties. ---------- (a) Newpark has provided to Tuboscope a true and complete list of all real property leased by Newpark or its Subsidiaries pursuant to leases providing for the occupancy of facilities in excess of 10,000 square feet (collectively "Material Leases").

(b) Newpark has provided to Tuboscope a true and complete list of all real property that Newpark or any of its Subsidiaries owns.

conducted, subject to such exceptions that would not be reasonably likely to have a Newpark Material Adverse Effect. Section 3.10. Agreements, Contracts and Commitments. Newpark has not ------------------------------------- breached, or received in writing any claim or notice that it has breached, any of the terms or conditions of any material agreement, contract or commitment filed as an exhibit to the Newpark SEC Reports ("Newpark Material Contracts") in such a manner as, individually or in the aggregate, are reasonably likely to have a Newpark Material Adverse Effect. Each Newpark Material Contract that has not expired by its terms is in full force and effect. Section 3.11. Litigation. Except as described in the Newpark SEC ---------- Reports filed prior to the date hereof, there is no action, suit or proceeding, claim, arbitration or investigation against Newpark pending or as to which Newpark has received any written notice of assertion, which, individually or in the aggregate, is reasonably likely to have a Newpark Material Adverse Effect or a material adverse effect on the ability of Newpark to consummate the transactions contemplated by this Agreement. Section 3.12. Environmental Matters. --------------------- (a) Except for matters that are specifically disclosed in the Newpark SEC Reports filed prior to the date hereof (with reference to a specifically named site or claim) and except for such matters that, individually or in the aggregate, are not reasonably likely to have a Newpark Material Adverse Effect: (i) Newpark and its Subsidiaries comply, and within all applicable statutes of limitations periods have complied, with all applicable Environmental Laws (as defined in Section 3.12(b)); (ii) neither Newpark nor its Subsidiaries are subject to liability for any Hazardous Substance disposal or contamination on any third party property; (iii) neither Newpark nor any of its Subsidiaries are subject to liability for any release of, or any exposure of any person or property to, any Hazardous Substance; (iv) neither Newpark nor any of its Subsidiaries has received any notice, demand, letter, claim or request for information alleging that Newpark or any of its Subsidiaries may be in violation of or liable under any Environmental Law; (v) neither Newpark nor any of its Subsidiaries is subject to any orders, decrees or injunctions issued by, or other arrangements with, any Governmental Entity or is subject to any indemnity or other agreement with any third party relating to liability under any Environmental Law or relating to Hazardous Substances; and (vi) there are no circumstances or conditions involving Newpark or any of its Subsidiaries that could reasonably be expected to cause Newpark or any of its Subsidiaries to become subject to any claims, liability, investigations or costs, or to restrictions on the ownership, use or transfer of any property of Newpark or any of its Subsidiaries, pursuant to any Environmental Law. (b) As used herein, the term "Environmental Law" means any federal, state, local or foreign law, regulation, order, decree, permit, authorization, opinion, common law or agency requirement relating to: (A) the protection, preservation, investigation, remediation or restoration of environmental quality, health and safety, or natural resources, or (B) noise, odor, wetlands, pollution, contamination or any injury or threat of injury to persons or property. 12

EXHIBIT 99.1 Tuboscope and Newpark Resources Announce Merger Plans; 50-50 Ownership Values Deal at Approximately $1.3 Billion June 24, 1999 04:28 PM HOUSTON--(BUSINESS WIRE)--June 24, 1999--Tuboscope ("Tuboscope") TBI and Newpark Resources Inc. ("Newpark") NR announced today that the companies have agreed to merge, creating a worldwide supplier of highly engineered products and services to the oil and gas industry with over $800 million in combined sales in 1998. Under the terms of a definitive merger agreement approved by both boards of directors and executed today, Newpark common shareholders would receive 0.65 common shares of Tuboscope for each common share of Newpark. At that ratio each shareholder group will own approximately 50% of the combined company. Tuboscope will be the surviving company with its name likely to be changed to reflect the integrated services to be provided. The proposed merger is subject to stockholder, lender, and regulatory approval and is expected to be accounted for as a purchase. The merger will enable the combined company to provide a comprehensive package of sophisticated drilling and production waste minimization and disposal technologies. The company plans to integrate Tuboscope's leading position in solids control products used to separate drilling waste from drilling fluids and Newpark's drilling fluid and waste minimization and disposal capabilities, to offer "one-stop" shopping for fluids and waste management for the drilling industry worldwide. James D. Cole, President, CEO and Chairman of Newpark will become Chairman and John F. Lauletta will be President and CEO of the new company. L.E. Simmons, current Chairman of Tuboscope, will chair an executive committee of the new board of directors which will be composed of directors from both companies. Joe Winkler will remain as Executive Vice President and Chief Financial Officer. W.T. Ballantine, current Executive Vice President of Newpark, will assume a senior management position with continued responsibility for key Newpark operating companies. "The oil and gas industry has moved quickly and prudently to reduce the environmental impact of drilling operations over the past several years," remarked Jim Cole. "This transaction will align leading technologies and capabilities to provide superior solutions to customers' drilling waste management challenges". Commented John Lauletta, "Newpark's theater of operations has traditionally been focused on the U.S. Gulf Coast. Tuboscope's infrastructure, spanning 49 countries, provides an extensive platform to accelerate the growth of products and services." Lauletta and Cole also remarked that cost savings from efficiency improvements are likely to arise from the merger, but declined to give estimates, saying only that both are committed to aggressive pursuit of improved efficiency and market growth initiatives. Lauletta added, "Besides the benefits of the strategic fit and synergies; the broader shareholder base, share liquidity, market capitalization, product and geographic diversity should increase value for our combined shareholders." Morgan Stanley Dean Witter provided a fairness opinion to Tuboscope's Board of Directors. Salomon Smith Barney provided a fairness opinion to Newpark's Board of Directors. The merger is expected to close in the third quarter of 1999.

Tuboscope is the world's leading supplier of oilfield internal tubular coating and tubular inspection services; oilfield solids control equipment and services; and coiled tubing and pressure control equipment to the petroleum industry. Additionally, it provides in-service inspection of pipelines; manufactures high pressure fiberglass tubulars; sells and leases advanced in- line inspection equipment to makers of oil country tubular goods; and provides quality assurance and inspection services to a diverse range of industries. Tuboscope is headquartered in Houston, Texas and services markets in 49 countries. 1998 revenues were $568 million. Newpark is a leading provider of integrated drilling fluids management, environmental and oilfield services to the natural gas exploration and production industry. Newpark is headquartered in Metairie, La. and services markets in Canada, the United States, Mexico and Venezuela. 1998 revenues were $257 million. The foregoing contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934.
