Item 5:  Other Events.

     On June 24, 1999, Newpark Resources, Inc., a Delaware corporation
("Newpark"), and Tuboscope Inc., a Delaware corporation ("Tuboscope"), agreed to
merge Newpark with and into Tuboscope (the "Merger").  The terms of the Merger
are set forth in an Agreement and Plan of Merger (the "Merger Agreement"), dated
as of June 24, 1999, between Tuboscope and Newpark.

     In the Merger, each share of Newpark's common stock will be converted into
0.65 share of Tuboscope common stock.  Tuboscope and Newpark issued a joint
press release announcing the execution of the Merger Agreement on June 24, 1999,
a copy of which is filed as Exhibit 99.1 hereto and which is incorporated herein
by reference.

     The Merger is intended to constitute a tax-free reorganization under the
Internal Revenue Code of 1986, as amended, and be accounted for as a purchase.

     Consummation of the Merger is subject to various conditions, including:
(i) receipt of necessary approvals by the stockholders of each of Tuboscope and
Newpark; (ii) the expiration or termination of applicable waiting periods under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the receipt of
requisite regulatory approvals from foreign and domestic regulatory authorities;
and (iii) registration of the shares of Tuboscope common stock to be issued in
connection with the Merger under the Securities Act of 1933, as amended, and the
listing of such shares on the New York Stock Exchange.

     In connection with the Merger Agreement, SCF-IV, L.P., a Delaware limited
partnership ("SCF") and holder of 150,000 shares of Newpark's Series A
Cumulative Perpetual Preferred Stock, entered into an agreement with Newpark and
Tuboscope pursuant to which SCF agreed to vote all of the shares of preferred
stock owned by it in favor of the Merger (the "SCF Agreement").

     The foregoing summary of the Merger Agreement and the SCF Agreement is
qualified in its entirety by reference to the text of the Merger Agreement and
the SCF Agreement, copies of which are filed as Exhibits 2.1 and 99.2 hereto,
respectively, and which are incorporated herein by reference.

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

<PAGE>

          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

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

          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

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
<PAGE>

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
<PAGE>

               (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
<PAGE>

               (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
<PAGE>

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
<PAGE>

(excluding partnerships, the general partnership interests of which held by such
party or any Subsidiary of such party do not have a majority of the voting
interest in such partnership) or (ii) at least a majority of the securities or
other interests having by their terms ordinary voting power to elect a majority
of the Board of Directors or others performing similar functions with respect to
such corporation or other organization is directly or indirectly owned or
controlled by such party or by any one or more of its Subsidiaries, or by such
party and one or more of its Subsidiaries.

          Section 3.02.  Newpark Capital Structure.
                         -------------------------

               (a) The authorized capital stock of Newpark consists of
100,000,000 shares of Common Stock and 1,000,000 shares of Preferred Stock
("Newpark Preferred Stock"). As of June 16, 1999, (i) 68,905,444 shares of
Newpark Common Stock were issued and outstanding, all of which are validly
issued, fully paid and nonassessable, (ii) 150,000 shares of Newpark Series A
Preferred Stock were issued and outstanding, all of which are validly issued,
fully paid and nonassessable, and (iii) no shares of Newpark Common Stock or
Newpark Preferred Stock were held in the treasury of Newpark or by Subsidiaries
of Newpark. The Newpark Disclosure Schedule shows the number of shares of
Newpark Common Stock reserved for future issuance pursuant to an outstanding
warrant (the "Newpark Warrant"), stock options and restricted stock awards
granted and outstanding as of June 16, 1999 and the plans under which such
options or shares of restricted stock were granted or issued (collectively, the
"Newpark Stock Plans"). Except as set forth in the Newpark Disclosure Schedule,
no change in such capitalization has occurred between June 16, 1999 and the date
of this Agreement. All shares of Newpark Common Stock subject to issuance as
specified above are duly authorized and, upon issuance on the terms and
conditions specified in the instruments pursuant to which they are issuable,
shall be validly issued, fully paid and nonassessable. There are no obligations,
contingent or otherwise, of Newpark or any of its Subsidiaries to repurchase,
redeem or otherwise acquire any shares of Newpark Common Stock or Newpark
Preferred Stock or the capital stock of any Subsidiary or to provide funds to or
make any material investment (in the form of a loan, capital contribution or
otherwise) in any such Subsidiary or any other entity other than guarantees of
obligations of Subsidiaries entered into in the ordinary course of business. 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.

               (b) Except as set forth in this Section 3.02 or as reserved for
future grants of securities under the Newpark Stock Plans or issuances upon
exercise of the Newpark Warrant, there are no equity securities of any class of
Newpark or any of its Subsidiaries, or any security exchangeable into or
exercisable for such equity securities, issued, reserved for issuance or
outstanding. Except as set forth in this Section 3.02, there are no options,
warrants, equity securities, calls, rights, commitments or agreements of any
character to which Newpark or any of its Subsidiaries is a party or by which it
is bound obligating Newpark or any of its Subsidiaries to issue, deliver or
sell, or cause to be issued, delivered or sold, additional shares of capital
stock of

                                       7
<PAGE>

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.

               (c) Newpark has received a written consent, in the form
previously delivered to Tuboscope, from the holder of a majority of the shares
of Newpark Series A Preferred Stock indicating such holder's consent to the
Merger.

          Section 3.03.  Authority; No Conflict; Required Filings and Consents.
                         -----------------------------------------------------

               (a) Newpark has all requisite corporate power and authority to
enter into this Agreement and to consummate the transactions contemplated by
this Agreement. The execution and delivery of this Agreement and the
consummation of the transactions contemplated by this Agreement by Newpark have
been duly authorized by all necessary corporate action on the part of Newpark,
subject only to the approval of the Merger by Newpark's stockholders under the
DGCL. This Agreement has been duly executed and delivered by Newpark and
constitutes the valid and binding obligation of Newpark, enforceable in
accordance with its terms, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors' rights and to general equity principles (the
"Bankruptcy and Equity Exception").

               (b) The execution and delivery of this Agreement by Newpark do
not, and the consummation of the transactions contemplated by this Agreement
will not, (i) conflict with, or result in any violation or breach of, any
provision of the certificate of incorporation or bylaws of Newpark, (ii) result
in any violation or breach of, or constitute (with or without notice or lapse of
time, or both) a default (or give rise to a right of termination, cancellation
or acceleration of any obligation or loss of any material benefit) under, or
require a consent or waiver under, any of the terms, conditions or provisions of
any note, bond, mortgage, indenture, lease, contract or other agreement,
instrument or obligation to which Newpark or any of its Subsidiaries is a party
or by which any of them or any of their properties or assets may be bound, or
(iii) conflict with or violate any permit, concession, franchise, license,
judgment, order, decree, statute, law, ordinance, rule or regulation applicable
to Newpark or any of its Subsidiaries or any of its or their properties or
assets, except in the case of (ii) and (iii) for any such conflicts, violations,
defaults, terminations, cancellations or accelerations which are not,
individually or in the aggregate, reasonably likely to have a Newpark Material
Adverse Effect.

               (c) No consent, approval, order or authorization of, or
registration, declaration or filing with, any court, administrative agency or
commission or other governmental authority or instrumentality ("Governmental
Entity") is required by or with respect to Newpark or any of its Subsidiaries in
connection with the execution and delivery of this Agreement or the consummation
of the transactions contemplated hereby, except for (i) the filing of the pre-
merger notification report under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended ("HSR Act"), (ii) the filing of the Certificate of
Merger with the Delaware Secretary of State, (iii)

                                       8
<PAGE>

the filing of the Joint Proxy Statement (as defined in Section 3.15 below) with
the Securities and Exchange Commission (the "SEC") in accordance with the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), (iv) such
consents, approvals, orders, authorizations, registrations, declarations and
filings as may be required under applicable state securities laws and the laws
of any foreign country and the European Union, and (v) such other consents,
authorizations, filings, approvals and registrations which, if not obtained or
made, would not be reasonably likely to have a Newpark Material Adverse Effect.

          Section 3.04.  SEC Filings; Financial Statements.
                         ---------------------------------

               (a) Newpark has filed and made available to Tuboscope all forms,
reports and documents required to be filed by Newpark with the SEC since January
1, 1996 other than registration statements on Form S-8 (collectively, the
"Newpark SEC Reports"). The Newpark SEC Reports (i) at the time filed, complied
in all material respects with the applicable requirements of the Securities Act
of 1933, as amended (the "Securities Act"), and the Exchange Act, as the case
may be, and (ii) did not at the time they were filed (or if amended or
superseded by a filing prior to the date of this Agreement, then on the date of
such filing) contain any untrue statement of a material fact or omit to state a
material fact required to be stated in such Newpark SEC Reports or necessary in
order to make the statements in such Newpark SEC Reports, in the light of the
circumstances under which they were made, not misleading.  None of Newpark's
Subsidiaries is required to file any forms, reports or other documents with the
SEC.

               (b) Each of the consolidated financial statements (including, in
each case, any related notes) contained in the Newpark SEC Reports complied as
to form in all material respects with the applicable published rules and
regulations of the SEC with respect thereto, was prepared in accordance with
generally accepted accounting principles applied on a consistent basis
throughout the periods involved (except as may be indicated in the notes to such
financial statements or, in the case of unaudited statements, as permitted by
Form 10-Q of the SEC) and fairly presented the consolidated financial position
of Newpark and its Subsidiaries as of the dates and the consolidated results of
its operations and cash flows for the periods indicated, except that the

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.

               (b) Newpark and each of its Subsidiaries have timely filed all
Tax Returns and reports required to be filed by them prior to the date of this
Agreement (taking into account extensions), except for any such returns which
are not likely, individually or in the aggregate, to have a Newpark Material
Adverse Effect. 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. Neither the Internal
Revenue Service (the "IRS") nor any other taxing

                                       10
<PAGE>

authority has asserted any claim for Taxes, or to the actual knowledge of the
executive officers of Newpark, is threatening to assert any claims for Taxes,
which claims, individually or in the aggregate, are reasonably likely 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.

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

leases, except where the existence of such defaults, individually or in the
aggregate, is not reasonably likely to have a Newpark Material Adverse Effect.

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

Effect: (a) Newpark or the identified Subsidiary has good and clear record and
marketable title to such property, free and clear of any security interest,
easement, covenant or other restriction, except for security interests,
easements, covenants and other restrictions which do not materially impair the

defects.

                                       11

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

have a Newpark Material Adverse Effect. Each Newpark Material Contract that has
not expired by its terms is in full force and effect.

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.

of its Subsidiaries, pursuant to any Environmental Law.

               (b) As used herein, the term "Environmental Law" means any

                         ----------------------

               (a) Newpark has listed in Section 3.13 of the Newpark Disclosure

contained in this Article IV are true and correct, except as set forth herein
and in the disclosure schedule delivered by Tuboscope to Newpark on or before
the date of this Agreement (the "Tuboscope

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 Tuboscope and its Subsidiaries, taken as a whole (a "Tuboscope
Material Adverse Effect"). Except as set forth in the Tuboscope SEC Reports (as
defined in Section 4.04) filed prior to the date hereof, neither Tuboscope nor
any of its Subsidiaries directly or indirectly owns any equity or similar
interest in, or any interest convertible into or exchangeable or exercisable

          Section 4.02.  Tuboscope Capital Structure.

1,424,700 shares of Tuboscope Common Stock were held in the treasury of
Tuboscope or by Subsidiaries of Tuboscope and (iii) no shares of Tuboscope
Preferred Stock were issued and outstanding. The Tuboscope Disclosure Schedule

and outstanding as of June 16, 1999 and the plans under which such options and
restricted stock awards were granted (collectively, the "Tuboscope Stock

Tuboscope Preferred Stock are issued and outstanding. All shares of Tuboscope
Common Stock subject to issuance as specified above are duly authorized and,
upon issuance on the terms and conditions specified in the instruments pursuant
to which they are issuable, shall be validly issued, fully paid and
nonassessable. There are no obligations, contingent or otherwise, of Tuboscope
or any of its Subsidiaries to repurchase, redeem or otherwise acquire any shares
of Tuboscope Common Stock or the capital stock of any Subsidiary or to provide
funds to or make any material investment (in the form of a loan, capital
contribution or otherwise) in any such Subsidiary or any other entity other than
guarantees of obligations of Subsidiaries entered into in the ordinary course of
business. All of the outstanding shares of capital stock of each of Tuboscope's
Subsidiaries are

                                       16
<PAGE>

shares (other than directors' qualifying shares in the case of foreign
Subsidiaries) are owned by Tuboscope or another Subsidiary free and clear of all
security interests, liens, claims, pledges, agreements, limitations in
Tuboscope's voting rights, charges or other encumbrances of any nature.

               (b) Except as set forth in this Section 4.02 or as reserved for
future grants of securities under the Tuboscope Stock Plans, there are no equity
securities of any class of Tuboscope or any of its Subsidiaries, or any security
exchangeable into or exercisable for such equity securities, issued, reserved
for issuance or outstanding. Except as set forth in this Section 4.02, there are
no options, warrants, equity securities, calls, rights, commitments or
agreements of any character to which Tuboscope or any of its Subsidiaries is a
party or by which it is bound obligating Tuboscope or any of its Subsidiaries to
issue, deliver or sell, or cause to be issued, delivered or sold, additional
shares of capital stock of Tuboscope or any of its Subsidiaries or obligating
Tuboscope 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 Tuboscope, there are no voting trusts,
proxies or other voting agreements or understandings with respect to the shares
of capital stock of Tuboscope.

               (a) Tuboscope has all requisite corporate power and authority to
enter into this Agreement and to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Tuboscope, subject only to the approval of the
Tuboscope Voting Proposal (as defined in Section 6.05) by Tuboscope's
stockholders. This Agreement has been duly executed and delivered by Tuboscope
and constitutes the valid and binding obligation of Tuboscope, enforceable in
accordance with its terms, subject to the Bankruptcy and Equity Exception.

               (b) The execution and delivery of this Agreement by Tuboscope do
not, and the consummation of the transactions contemplated hereby will not, (i)
conflict with, or result in any violation or breach of, any provision of the
certificate of incorporation or bylaws of Tuboscope, (ii) result in any
violation or breach of, or constitute (with or without notice or lapse of time,
or both) a default (or give rise to a right of termination, cancellation or
acceleration of any obligation or loss of any material benefit) under, or
require a consent or waiver under, any of the terms, conditions or provisions of
any note, bond, mortgage, indenture, lease, contract or other agreement,
instrument or obligation to which Tuboscope or any of its Subsidiaries is a
party or by which any of them or any of their properties or assets may be bound,
or (iii) conflict with or violate any permit, concession, franchise, license,
judgment, order, decree, statute, law, ordinance, rule or regulation applicable
to Tuboscope or any of its Subsidiaries or any of its or their properties or
assets, except in the case of (ii) and (iii) for any such conflicts, violations,
defaults, terminations, cancellations or accelerations which are not,

          Section 4.04.  SEC Filings; Financial Statements.
                         ---------------------------------

               (a) Tuboscope has filed and made available to Newpark all forms,
reports and documents required to be filed by Tuboscope with the SEC since
January 1, 1996 other than registration statements on Form S-8 (collectively,
the "Tuboscope SEC Reports").  The Tuboscope SEC Reports (i) at the time filed,
complied in all material respects with the applicable requirements of the
Securities Act and the Exchange Act, as the case may be, and (ii) did not at the
time they were filed (or if amended or superseded by a filing prior to the date
of this Agreement, then on the date of such filing) contain any untrue statement
of a material fact or omit to state a material fact required to be stated in
such Tuboscope SEC Reports or necessary in order to make the statements in such
Tuboscope SEC Reports, in the light of the circumstances under which they were
made, not misleading.  None of Tuboscope's Subsidiaries is required to file any
forms, reports or other documents with the SEC.

               (b) Each of the consolidated financial statements (including, in
each case, any related notes) contained in the Tuboscope SEC Reports complied as
to form in all material respects with the applicable published rules and
regulations of the SEC with respect thereto, was prepared in accordance with
generally accepted accounting principles applied on a consistent basis
throughout the periods involved (except as may be indicated in the notes to such
financial statements or, in the case of unaudited statements, as permitted by
Form 10-Q of the SEC) and fairly presented the consolidated financial position
of Tuboscope and its Subsidiaries as of the dates and the consolidated results
of its operations and cash flows for the periods indicated, except that the
unaudited interim financial statements were or are subject to normal and
recurring year-end adjustments which were not or are not expected to be material
in amount. The audited balance sheet of Tuboscope as of December 31, 1998 is
referred to herein as the "Tuboscope Balance Sheet."

          Section 4.05.  No Undisclosed Liabilities.  Except as disclosed in the
                         --------------------------
Tuboscope 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, Tuboscope 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

                                       18
<PAGE>

generally accepted accounting principles), and whether due or to become due,
which individually or in the aggregate are reasonably likely to have a Tuboscope
Material Adverse Effect.

          Section 4.06.  Absence of Certain Changes or Events.  Except as
                         ------------------------------------
disclosed in the Tuboscope SEC Reports filed prior to the date hereof, since the
date of the Tuboscope Balance Sheet, Tuboscope 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 Tuboscope 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
Tuboscope is aware that, individually or in the aggregate, has had, or is
reasonably likely to have, a Tuboscope Material Adverse Effect (other than
developments that are the effect or result of actions to be taken by Newpark 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 Tuboscope or any of its Subsidiaries
having a Tuboscope Material Adverse Effect; (iii) any material change by
Tuboscope in its accounting methods, principles or practices to which Newpark
has not previously consented in writing; (iv) any revaluation by Tuboscope of
any of its assets having a Tuboscope Material Adverse Effect; or (v) any other
action or event that would have required the consent of Newpark pursuant to
Section 5.02 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 Tuboscope Material Adverse Effect.

          Section 4.07.  Taxes.  Tuboscope and each of its Subsidiaries have
                         -----
timely filed all Tax Returns and reports required to be filed by them prior to
the date of this Agreement (taking into account extensions), except for any such
returns which are not likely, individually or in the aggregate, to have a
Tuboscope Material Adverse Effect. 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 Tuboscope
Material Adverse Effect. Tuboscope and each of its Subsidiaries has paid (or
Tuboscope has paid on its Subsidiaries' behalf) all Taxes shown as due on such
Tax Returns, and Tuboscope's most recent consolidated financial statements
reflect an adequate reserve for all Taxes payable by Tuboscope 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 Tuboscope
Material Adverse Effect. Neither the IRS nor any other taxing authority has
asserted any claim for Taxes, or to the actual knowledge of the executive
officers of Tuboscope, is threatening to assert any claims for Taxes, which
claims, individually or in the aggregate, are reasonably likely to have a
Tuboscope Material Adverse Effect. No deficiencies for any Taxes (other than
those which are not reasonably likely, individually or in the aggregate, to have
a Tuboscope Material Adverse Effect) have been proposed, asserted or assessed
against Tuboscope or any of its Subsidiaries that have not been fully paid or
adequately provided for in the appropriate financial statements of Tuboscope and
its Subsidiaries, no requests for waivers of the time to assess any Taxes are
pending, and none of Tuboscope or any of its Subsidiaries have waived any
statute of limitations in respect of Taxes or agreed to any extension of time
with

                                       19
<PAGE>

respect to a Tax assessment or deficiency. Tuboscope 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 Tuboscope
Material Adverse Effect. Neither Tuboscope 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 Tuboscope Material Adverse Effect. There are no liens for Taxes
upon the assets of Tuboscope 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 Tuboscope Material Adverse Effect.

aggregate, is not reasonably likely to have a Tuboscope Material Adverse Effect.

               (b) Tuboscope has provided to Newpark a true and complete list of
all real property that Tuboscope or any of its Subsidiaries owns. With respect
to each such item of real property, except for such matters that, individually
or in the aggregate, are not reasonably likely to have a Tuboscope Material
Adverse Effect: (a) Tuboscope or the identified Subsidiary has good and clear
record and marketable title to such property free and clear of any security
interest, easement, covenant or other restriction, except for security
interests, easements, covenants and other restrictions which do not materially
impair the current uses or occupancy of such property; and (b) the improvements
constructed on such property are in good condition, and all mechanical and
utility systems servicing such improvements are in good condition, free in each
case of material defects.

names, service marks, copyrights, and any applications for such trademarks,
trade names, service marks and copyrights, know-how, computer software programs
or applications, and tangible or intangible proprietary information or material
that are necessary to conduct the business of Tuboscope as currently conducted,
subject to such exceptions that would not be reasonably likely to have a
Tuboscope Material Adverse Effect.

          Section 4.10.  Agreements, Contracts and Commitments.  Tuboscope 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 Tuboscope SEC Reports ("Tuboscope Material
Contracts") in such a manner as, individually or in the aggregate, are
reasonably likely to have a Tuboscope Material Adverse Effect. Each Tuboscope
Material Contract that has not expired by its terms is in full force and effect.

Effect or a material adverse effect on the ability of Tuboscope to consummate
the transactions contemplated by this Agreement.

                         ---------------------

are no circumstances or conditions involving Tuboscope or any of its
Subsidiaries that could reasonably be expected to cause Tuboscope 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
Tuboscope or any of its Subsidiaries, pursuant to any Environmental Law.

          Section 4.13.  Employee Benefit Plans.

through any officer, director, employee, financial advisor, representative or
agent of such party (i) solicit, initiate, or encourage any inquiries or
proposals that constitute, or could reasonably be expected to lead to, a
proposal or offer for an Alternative Transaction (as defined below) involving
such party or any of its Subsidiaries (any of the foregoing inquiries or
proposals being referred to in this Agreement as an "Acquisition Proposal"),
(ii) engage in negotiations or discussions concerning, or provide any non-public
information to any person or entity relating to, any Acquisition Proposal, or

entering into discussions or negotiations with, any person or entity in
connection with an unsolicited bona fide written Acquisition Proposal by such
person or entity or recommending an unsolicited bona fide written Acquisition
Proposal to the stockholders of such party, if and only to the extent that (1)
the Board of Directors of such party believes in good faith (after consultation
with its financial advisor) that such Acquisition Proposal is reasonably capable
of being completed on the terms proposed and, after taking into account the
strategic benefits anticipated to be derived from the Merger and the long-term
prospects of Newpark and Tuboscope as a combined company, would, if consummated,
result in a transaction more favorable than the transaction contemplated by this
Agreement (any such more favorable Acquisition Proposal being referred to in
this Agreement as a "Superior Proposal") and the Board of Directors of such
party determines in good faith after consultation with outside legal counsel
that failure to take such action would be reasonably likely to constitute a
breach of the fiduciary duties of such Board of Directors to stockholders under
applicable law, (2) prior to furnishing such non-public information to, or
entering into discussions or negotiations with, such person or entity, such
Board of Directors receives from such person or entity an executed
confidentiality agreement with terms no less favorable to such party than those

party, such party has complied with the provisions of Section 6.01(b); or (B)
complying with Rule 14e-2 promulgated under the Exchange Act with regard to an
Acquisition Proposal.

               (b) Tuboscope and Newpark shall each notify the other party
immediately after receipt by Tuboscope or Newpark (or their advisors) of any
Acquisition Proposal or any request for nonpublic information in connection with
an Acquisition Proposal or for access to the properties, books or records of
such party by any person or entity that informs such party that it is
considering making, or has made, an Acquisition Proposal.  Such notice shall be
made orally and in writing and shall indicate in reasonable detail the identity
of the offer or and the terms and conditions of such proposal, inquiry or
contact.  Such party shall, to the extent permitted by law, continue to keep the
other party hereto informed, on a current basis, of the status of any such

pursuant to the Merger; provided that the Board of Directors of Newpark may
withdraw such recommendation if (but only if) (i) the Board of Directors of
Newpark has received a Superior Proposal, and (ii) such Board of Directors upon
advice of its outside legal counsel determines that it is reasonably likely that
a failure to recommend such Superior Proposal would constitute a breach of its
fiduciary duties under applicable law, and the Board of Directors of Tuboscope
may withdraw such recommendation if (but only if) (i) the Board of Directors of
Tuboscope has received a Superior Proposal, and (ii) such Board of Directors
upon advice of its outside legal counsel determines that it is reasonably likely

asserted or claimed prior to, at or after the Effective Time, to the fullest
extent that Newpark would have been permitted under Delaware law and its
certificate of incorporation or bylaws in effect on the date hereof to indemnify
such Indemnified Party (and Tuboscope shall also advance expenses as incurred to
the fullest extent permitted under applicable law, provided the Indemnified
Party to whom expenses are advanced provides an undertaking to repay such

                  (b)    The provisions of this Section 6.12 are intended to be
an addition to the rights otherwise available to the current and former officers

               respect to such shares of Newpark Common Stock
               substantially similar to the registration rights

               pursuant to that certain Registration Rights Agreement
               dated as of April 24, 1996 by and among Tuboscope, SCF-

                           (B) if Tuboscope does not request payment
               under subparagraph 8.03(f)(ii)(A), Newpark shall pay to

               date of the closing of the applicable Alternative
               Transaction; and

          payable by Tuboscope in either of the following manners,
          which manner shall be selected by Newpark in its sole and

               request from Newpark for payment of the Tuboscope
               Termination Fee in shares of Tuboscope Common Stock
               (which request shall be made no earlier than the
               earliest date on which an obligation to pay the
               Tuboscope Termination Fee is triggered and no later
               than twelve months after the termination of this
               Agreement), Tuboscope shall issue to Newpark within
               five business days an amount of Tuboscope Common Stock
               having a Current Market Value of $25,000,000 and shall
               provide Newpark with registration rights with respect
               to such shares of Tuboscope Common Stock substantially
               similar to the registration rights provided to SCF-III,
               L.P. ("SCF-III") by Tuboscope pursuant to the Standard
               Registration Rights Agreement; provided, however, that
               such registration rights shall be subordinate to the
               rights of the holders of registration rights under the
               Standard Registration Rights Agreement as of the date
               of this Agreement; or

                           (B) if Newpark does not request payment
               under subparagraph 8.03(f)(iii)(A), Tuboscope shall pay

               date of the closing of the applicable Alternative
               Transaction.

          For purposes of this subsection 8.03(f), "Current Market Price" shall

average of the last reported sales prices of such security on the NYSE on each
of the five trading days immediately preceding the date of this Agreement.

either (i) a transaction pursuant to which any person (or group of persons)
other than Tuboscope or Newpark or their respective affiliates (a "Third
Party"), acquires more than 25% of the outstanding shares of Newpark Common

            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.
