                                  THE COMPANY

     Newpark is a leading provider of integrated environmental and oilfield
services to the oil and gas exploration and production industry in the U.S. Gulf
Coast area, principally in Louisiana and Texas. Services provided, either
individually or as part of a comprehensive package, include: (i) oilfield waste
services utilizing patented and proprietary technology, including processing and
disposal of nonhazardous oilfield waste ("NOW") and oilfield waste that is
contaminated with naturally occurring radioactive material ("NORM"); (ii)
drilling fluids products and services and related engineering and technical
services; (iii) mat rentals and sales in which patented prefabricated wooden
mats are used as temporary access roads and worksites in oilfield and other
construction applications; and (iv) other integrated oilfield services,
including construction, design and engineering services.  In order to take
advantage of many customers' increasing focus on outsourcing and vendor
consolidation, Newpark has integrated its drilling fluids products and services
with its mat services and waste disposal services to provide a "one-stop shop"
approach to solving customers' problems.

     Newpark collects, processes and disposes of oilfield waste, primarily NOW
and NORM. Newpark processes NOW received at its facilities primarily for
injection into environmentally secure geologic formations deep underground and,
to a lesser extent, for disposal at certain landfarming facilities.  NOW that is
not injected or landfarmed is processed by Newpark into a product which is used
as intermediate daily cover material or cell liner and construction material at
municipal waste landfills. In 1994, Newpark began processing and disposing of
NORM waste.  Since June 1996, Newpark has operated under a license authorizing
the direct injection of NORM into disposal wells at Newpark's Big Hill, Texas
facility, the only offsite facility in the U.S. Gulf Coast licensed for the
direct injection of NORM.

     Newpark is a full-service provider of drilling fluids and associated
engineering and technical services to the onshore and offshore oil and gas
exploration industry in the Gulf Coast areas of Louisiana and Texas.  Newpark
focuses on providing unique solutions to highly technical drilling projects
involving complex conditions, as these projects require critical engineering
support of the fluids system during the drilling process in order to ensure
optimal performance at the lowest total well cost.  Newpark has established its
own barite grinding capacity in order to provide a supply of critical raw
materials for its drilling fluids operations.  Additionally, Newpark has
initiated a process to recycle a portion of the drilling fluids received as
waste in its NOW disposal business, in order to (i) recover barite and other key
chemical components for reuse in the production of drilling fluids, (ii) reduce
the costs of materials in producing drilling fluids and (iii) expand the
available supply of drilling fluids.

                                       3
<PAGE>
 
     In its mat business, Newpark uses patented interlocking wooden mat systems
to provide temporary access roads and worksites in unstable soil conditions,
primarily in support of oil and gas exploration operations along the U.S. Gulf
Coast.  In response to increasing environmental regulations, in 1994, Newpark
began marketing its mat services for use in the construction of pipelines,
electrical distribution systems and highways in and through wetlands
environments.  As a result, this new market for Newpark's mat business has
broadened the geographic area served by Newpark to include the coastal areas of
the Southeastern U.S., particularly Florida and Georgia.  Newpark also markets
its mat services to the oil and gas exploration industries in Venezuela and
Algeria.

     Newpark also provides a comprehensive range of other environmental and
oilfield services for its customers' oil and gas exploration and production
activities, including site assessment, waste pit design, construction and
installation, regulatory compliance assistance, site remediation and site
closure, construction services, hook-up and connection of wells and installation
of production equipment.

     Newpark was organized in 1932 as a Nevada corporation and in April 1991
changed its state of incorporation to Delaware.  Newpark's principal executive
offices are located at 3850 North Causeway Boulevard, Suite 1770, Metairie,
Louisiana 70002, and its telephone number is (504) 838-8222.

                                  RISK FACTORS

     In addition to the other information contained in or incorporated by
reference into this Prospectus, prospective investors should carefully consider
the following factors relating to the business of Newpark in evaluating an
investment in the Common Stock.

DEPENDENCE ON OIL AND GAS INDUSTRY

     Demand for Newpark's environmental and oilfield services depends in large
part upon the level of exploration and production of oil and gas and the
industry's willingness to spend capital on environmental and oilfield services,
which in turn depends on oil and gas prices, expectations about future prices,
the cost of exploring for, producing and delivering oil and gas, the discovery
rate of new oil and gas reserves and the ability of oil and gas companies to
raise capital.  Domestic and international political, military, regulatory and
economic conditions also affect the industry.  Prices for oil and gas
historically have been volatile and have reacted to changes in the supply of and
the demand for oil and natural gas, domestic and worldwide economic conditions
and political instability in oil producing countries.  No assurance can be given
that current levels of oil and gas activities will be maintained or that demand
for Newpark's services will reflect the level of such activities.  Prices for
oil and natural gas are expected to continue to be volatile and affect the
demand for Newpark's services.  Shortages of critical equipment and trained
personnel to operate such equipment also may limit the level of drilling
activity in the oil and gas industry.  A material decline in oil or natural gas
prices or activities could materially affect the demand for Newpark's services
and, therefore, Newpark's consolidated financial statements.

IMPACT OF GOVERNMENT REGULATIONS

     Newpark believes that the demand for its principal environmental services
is directly related to regulation of NOW and NORM.  Rescission or relaxation of
such regulations, or a failure of governmental authorities to enforce such
regulations, could result in decreased demand for Newpark's

                                       4
<PAGE>
 
services and, therefore, could materially affect Newpark's consolidated
financial statements.  Newpark's business may also be adversely affected by new
regulations or changes in other applicable regulations.

     NOW is currently exempt from the principal Federal statute governing the
handling of hazardous waste.  In recent years, proposals have been made to
rescind this exemption.  The repeal or modification of the exemption covering
NOW or modification of applicable regulations or their interpretation regarding
the treatment and/or disposal of NOW or NORM waste could require Newpark to
alter significantly its method of doing business.  Such repeal or modification
could have a material adverse effect on Newpark's consolidated financial
statements.

LOSS OF TECHNOLOGY RIGHTS

     Newpark has been granted U.S. patents on certain aspects of its system for
processing and disposing of NOW and NORM.  There is no assurance that such
patents will give Newpark a meaningful competitive advantage.  In addition, the
environmental services business in the oilfield could be impacted by future
technological change and innovation, which could result in a reduction in the
amount of waste being generated or alternative methods of disposal being
developed.

COMPETITION

     The processing of NOW and NORM waste is a relatively new industry.
Competition in this market can be expected to increase as the industry develops.
In the meantime, Newpark expects to encounter significant competition from third
party competitors in connection with any proposed expansion into additional
geographic areas and services.  Barriers to entry by competitors for Newpark's
environmental and oilfield services are low.  Therefore, competitive products
and services have been and may be successfully developed and marketed by others.
Newpark also faces competition from oil and gas producing customers who are
continually seeking to enhance and develop their own methods of disposal instead
of utilizing the services of third party NOW and NORM disposal companies such as
Newpark.  The desire to use such internal disposal methods could be increased by
future technological change and innovation and could limit the ability of
Newpark to increase prices.  The increased use by Newpark's oil and gas
producing customers of their own disposal methods and other competitive factors
could have a material adverse effect on Newpark's consolidated financial
statements.  Newpark also faces competition in the drilling fluids market, where
there are several larger companies that may have both lower capital costs and
greater geographic coverage than Newpark, as well as numerous smaller companies
that may have a lower total cost structure.

FAILURE TO COMPLY WITH GOVERNMENTAL REGULATIONS

     Newpark's business is subject to numerous Federal, state and local laws,
regulations and policies that govern environmental protection, zoning and other
matters.  These laws and regulations have changed frequently in the past and it
is reasonable to expect additional changes in the future.  If existing
regulatory requirements change, Newpark may be required to make significant
unanticipated capital and operating expenditures.  Although Newpark believes
that it is presently in material compliance with applicable laws and
regulations, there is no assurance that its operations will continue to comply
with future laws and regulations.  Governmental authorities may seek to impose
fines and penalties on Newpark or to revoke or deny the issuance or renewal of
operating permits for failure to comply with applicable laws and regulations.
Under such circumstances, Newpark might be required to curtail or

                                       5
<PAGE>
 
cease operations or conduct site remediation or other corrective action, which
could have a material adverse effect on Newpark's consolidated financial
statements.

POTENTIAL ENVIRONMENTAL LIABILITY; INSUFFICIENCY OF INSURANCE

     Newpark's business exposes it to the risk of harmful substances escaping
into the environment, resulting in personal injury or loss of life, severe
damage to or destruction of property, environmental damage and suspension of
operations.  The current and past activities of Newpark and the activities of
its former divisions and subsidiaries could result in the imposition of
substantial environmental, regulatory and other liabilities on Newpark,
including the costs of cleanup of contaminated sites and site closure
obligations.  Such liabilities could also be imposed on the basis of negligence,
strict liability, breach of contract with customers or, in many instances, as a
result of contractual indemnification by Newpark of its customers in the normal
course of its business.  Injection wells have been used for many years for
disposal of oilfield waste; however, certain aspects of Newpark's technology
have not been used previously by others and the future performance of such
technology is uncertain.

     While Newpark maintains liability insurance, the insurance is subject to
coverage limits and certain policies exclude coverage for damages resulting from
environmental contamination.  Although there are currently numerous sources from
which such coverage may be obtained, there can be no assurance that insurance
will continue to be available to Newpark on commercially reasonable terms, that
the possible types of liabilities that may be incurred by Newpark will be
covered by its insurance, that Newpark's insurance carriers will be able to meet
their obligations under the policies or that the dollar amount of such
liabilities will not exceed Newpark's policy limits.  Even a partially uninsured
claim, if successful and of significant magnitude, could have a material adverse
effect on Newpark's consolidated financial statements.

RELIANCE ON KEY PERSONNEL

     Newpark is dependent upon the efforts and talents of its executive officers
and certain key personnel.  Loss of the services of one or more of these persons
could adversely affect the operations of Newpark.  None of Newpark's executive
officers is covered by a long-term employment contract.

PREFERRED STOCK

     The Board of Directors of Newpark is authorized to issue, without further
stockholder action, up to 1,000,000 shares of Preferred Stock with rights that
could adversely affect the rights of holders of Newpark Common Stock.  No shares
of Preferred Stock are presently outstanding, and Newpark has no present plans
to issue any such shares.  The issuance of shares of Preferred Stock under
certain circumstances could have the effect of delaying, deterring or preventing
a change in control of Newpark or other corporate action and of discouraging
bids for Newpark Common Stock at a premium.

     On July 24, 1997, Newpark acquired Bockmon Construction Company, Inc., a
Texas corporation ("Bockmon"), and its related company, Bockmon Construction of
Louisiana, Inc., a Texas corporation ("Bockmon Louisiana"). The Selling
Stockholders and their father were the sole stockholders of Bockmon, and the 
Selling Stockholders were the sole stockholders of Bockmon Louisiana. In the
acquisition, all of the issued and outstanding shares of capital stock of
Bockmon and Bockmon Louisiana were exchanged for an aggregate of 502,000 shares
of Newpark Common Stock, with Bockmon and Bockmon Louisiana becoming wholly-
owned subsidiaries of Newpark. In connection with the acquisition, each of the
former stockholders of Bockmon entered into noncompetition agreements covering
competition in the site construction industry in the States of Louisiana, Texas,
Mississippi and Alabama and the Gulf of Mexico, until July 24, 2002. No
additional consideration was paid by Newpark for these noncompetition
agreements. Concurrent with the acquisition, each of the Selling Stockholders
entered into employment agreements with Bockmon, which provide for the
employment of each of the Selling Stockholders as Vice Presidents of Bockmon at
a salary of $91,000 per year. The employment agreements continue in effect until
July 31, 2000, and automatically renew for successive 12-month periods
thereafter unless terminated by either party.

     Newpark granted to the Selling Stockholders certain rights with respect to
the registration under the Securities Act of the shares of Common Stock issued
in the foregoing acquisition transaction, and the Shares offered hereby are
being so registered pursuant to the exercise of such registration rights.  In
accordance with the terms of such registration rights, Newpark will pay
substantially all of the expenses of this offering.

     Each of the transactions described above were negotiated at arms' length,
and Newpark believes that the terms of such transactions were commercially
reasonable in the circumstances.

                              PLAN OF DISTRIBUTION

     The Shares may be sold from time to time by the Selling Stockholders or by
pledgees, donees, transferees or other successors-in-interest of the Selling
Stockholders.  Such sales may be made on the New York Stock Exchange or
otherwise, at prices and at terms then prevailing, at prices related to the then
current market price or in negotiated transactions.  The Shares may be sold by
any one or more of the following methods: (a) ordinary brokerage transactions
and transactions in which the broker solicits purchasers; (b) purchases by a
broker or dealer as principal and resales by such broker or dealer for its
account pursuant to this Prospectus; and (c) block trades or exchange
distributions in accordance with the rules of such exchange.  In effecting
sales, brokers or dealers engaged by the Selling Stockholders may arrange for
other brokers or dealers to participate.  Brokers or dealers will receive
commissions or discounts from the Selling Stockholders in amounts to be
negotiated prior to the sale.  Such brokers or dealers and any other
participating brokers or dealers may be deemed to be "underwriters" within the
meaning of the Securities Act, and the compensation received by them may be
deemed to be underwriting commissions or discounts.

     Upon the Company being notified by a Selling Stockholder that any material
arrangement has been entered into with a broker or dealer for the sale of any
Shares covered by this Prospectus, a prospectus supplement, if required, will be
distributed which will set forth the name of the participating brokers or
dealers, the number of Shares involved, the price at which such Shares were sold
and the commissions paid or discounts or concessions allowed to such brokers or
dealers.  In certain jurisdictions, the Shares may be offered or sold in such
jurisdictions only through registered or licensed brokers or dealers.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the General Corporation Law of the State of Delaware (the
"GCL") permits a corporation to, and the registrant's bylaws require that it,
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (other than an action by or in
the right of the corporation), by reason of the fact that he is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred in connection with such action,
suit or proceeding if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful.

     As permitted under Section 145 of the GCL, the registrant's bylaws also
provide that it shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor by
reason of the fact that he is or was a director, officer employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation.  However, in such an action by or on behalf of a corporation, no
indemnification may be made in respect of any claim, issue or matter as to which
the person is adjudged liable for negligence or misconduct in the performance of
his duty to the corporation unless, and only to the extent that the court
determines that, despite the adjudication of liability but in view of all the
circumstances, the person is fairly and reasonably entitled to indemnity for
such expenses which the court shall deem proper.

     In addition, the indemnification provided by section 145 shall not be
deemed exclusive of any other rights to which a person seeking indemnification
may be entitled under any bylaw, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding such office.

                                     II-1
<PAGE>
 
     The registrant's Certificate of Incorporation (the "Certificate") provides
that the registrant shall indemnify, to the fullest extent permitted by law,
each of its officers, directors, employees and agents who was or is a party to,
or is threatened to be made a party to, any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that such person is or was a director,
officer, employee or agent of the registrant.  The Certificate also provides
that, to the fullest extent permitted by law, no director of the registrant
shall be liable to the registrant or its stockholders for monetary damages for
breach of his fiduciary duty as a director.

     The Certificate also provides that the registrant may purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the registrant, or is serving at the request of the registrant as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise against any liability
incurred by such person in any such capacity, or arising out of his status as
such, regardless of whether the registrant is empowered to indemnify such person
under the provisions of law.  Newpark does not currently maintain any such
insurance.

ITEM 17.  UNDERTAKINGS

A.   The registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

          (i) To include any prospectus required by section 10(a)(3) of the
Securities Act of 1933;

          (ii) To reflect in the prospectus any facts or events arising after
the effective date of the Registration Statement (or the most recent post-
effective amendment thereof) which, individually

                                     II-2
<PAGE>
 
or in the aggregate, represent a fundamental change in the information set forth
in the Registration Statement.  Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any deviation
from the low or high end of the estimated maximum offering range may be
reflected in the form of prospectus filed with the Commission pursuant to Rule
424(b) if, in the aggregate, the changes in volume and price represent no more
that a 20% change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective Registration Statement.

          (iii)  To include any material information with respect to the plan of
distribution not previously disclosed in the Registration Statement or any
material change to such information in the Registration Statement;

provided, however, that paragraphs (A)(1)(i) and (A)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in this Registration Statement.

     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (4) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.

B.   The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
related to the securities offered therein, and the offering of such securities
at the time shall be deemed to be the initial bona fide offering thereof.

C.   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable.  In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

with reference to the following facts:

          A.  The Stockholders own beneficially and of record 100% of the
outstanding capital stock (the "Target Shares") of BOCKMON CONSTRUCTION COMPANY,
INC., a Texas corporation ("Bockmon") and BOCKMON CONSTRUCTION COMPANY OF
LOUISIANA, INC., a Texas corporation ("Bockmon Louisiana") (each a "Company,"
and, together, the "Companies").  Each reference to "the Companies" herein means
either or both of them or, with respect to negative statements, neither nor both
of them.

          B.  The Companies are engaged together in providing construction and
site preparation services to the oil and gas industry in the Gulf Coast region.

          C.  The parties intend that this Agreement shall constitute a plan of
reorganization (the "Plan") of the type described in Section 368(a)(1)(B) of the
Internal Revenue Code of 1986, as amended (the "Code") and that the transaction
will be treated as a "pooling of interests" for accounting purposes.  The Plan
comprises the acquisition by Newpark of the Target Shares (including the
goodwill of the Companies associated therewith) from the Stockholders solely in
exchange for 251,000 newly issued shares of voting Common Stock of Newpark (the
"Newpark Shares").  Such transaction is sometimes referred to herein as the
"Exchange," and the consummation of the Exchange on the date hereof is sometimes
referred to herein as the "Closing."

          D.  Newpark and the Stockholders believe that it is in their best
interests to adopt the Plan and consummate the Exchange.

          NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the parties agree as follows:

          1. Plan of Reorganization.
       
             1.1 Adoption of Plan. Newpark and the Stockholders hereby adopt the
plan of reorganization herein set forth.

             1.2 Exchange of Shares.  Concurrently with the execution of this
Agreement, and subject to all of the terms hereof, the Stockholders will deliver
to Newpark certificates representing all of the Target Shares, duly endorsed for
transfer to Newpark or accompanied by separate stock powers so endorsed, and
Newpark will issue and deliver certificates representing the Newpark Shares to
the Stockholders, in proportion to their ownership of the Target Shares.  No
fractional Newpark Shares will be issued; if fractional shares otherwise would
issue, the Stockholders shall instruct Newpark as to the rounding of such
shares.
<PAGE>
 
          1.3 Securities Act Legend on Newpark Shares.  Each Stockholder hereby
agrees that he will not offer to sell, transfer or otherwise dispose of any of
the Newpark Shares issued to him pursuant to the Exchange, except in accordance
with the applicable provisions of the "Securities Act" and the "Rules and
Regulations" (as such terms are defined in Section 15).  Certificates
representing the Newpark Shares initially will bear the following legend:

  "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
  SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED
  OF UNLESS REGISTERED UNDER SAID ACT OR UNLESS AN EXEMPTION FROM SUCH
  REGISTRATION IS AVAILABLE IN THE OPINION OF COUNSEL FOR THE ISSUER."

          1.4 Pooling of Interests Restriction. Each Stockholder hereby agrees
that he will not offer to sell, transfer or otherwise dispose of any of the
Newpark Shares issued to him pursuant to the Exchange until such time as
financial results covering at least 30 days of combined operations of Newpark
and the Companies have been published within the meaning of Section 201.01 of
the Commission's Codification of Financial Reporting Policies.

  2. Ancillary Agreements.

          2.1 Noncompetition Agreements. At the Closing, as a necessary incident
of the Exchange, Newpark and the Stockholders will execute and deliver
noncompetition agreements substantially as set forth in Exhibit 2.1 attached to
this Agreement.

          2.2 Registration Rights Agreement. On the Closing Date, Newpark and
the Stockholders will execute and deliver a Registration Rights Agreement
substantially as set forth in Exhibit 2.2 attached to this Agreement.

  3. Representations and Warranties of the Stockholders.

          A.  Except as otherwise specifically set forth in a letter ("the
Disclosure Letter") delivered by the Stockholders to Newpark prior to the
execution hereof, the Stockholders hereby jointly and severally warrant and
represent the following (the truth and accuracy of each of which shall
constitute a condition precedent to Newpark's obligations to consummate the
Exchange and issue the Newpark Shares):

          3.1 Organization and Good Standing of the Companies.

              3.1.1 Each Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of Texas, has full
corporate power and authority to carry on its business as now conducted by it
and is entitled to own or lease and operate its properties and assets now owned
or leased and operated by it. Each Company is duly qualified and in good
standing as a foreign corporation in each jurisdiction where the character or
location of the assets owned by such Company or the nature of the business
transacted by such Company require such

                                      -2-
<PAGE>
 
qualification, except where failure to be so qualified would not have a
"Material Adverse Effect" (as defined in Section 15).  The Disclosure Letter
includes, for each Company, a list of the jurisdictions in which such Company is
qualified to do business.

          3.1.2 The Stockholders have furnished to Newpark complete and correct
copies of each Company's Articles of Incorporation and Bylaws as in effect on
the date hereof.

          3.1.3 The Stockholders have heretofore made available to Newpark for
its examination copies of the minute books, stock certificate books and
corporate seal of each Company. Said minute books are accurate in all material
respects and reflect all resolutions adopted and all material actions expressly
authorized or ratified by the stockholders and directors of such Company. The
stock certificate books reflect all issuances, transfers and cancellations of
capital stock of such Company.

      3.2 Capitalization.

          3.2.1 The authorized capital stock of Bockmon consists of 20,000
shares of stock, $10.00 par value per share, of which 7,200 shares are issued
and outstanding as of the date hereof. The authorized capital stock of Bockmon
Louisiana consists of 1,000 shares of stock, $1.00 par value per share, of which
1,000 shares are issued and outstanding as of the date hereof. All such issued
and outstanding shares are validly issued, fully paid and nonassessable. The
Disclosure Letter includes the names, addresses and social security numbers of,
and the number of the Target Shares owned by, each of the Stockholders.

          3.2.2 There are no options, warrants, subscriptions or other rights
outstanding for the purchase of, and all securities convertible into, capital
stock of either Company.  No shares of either Company are held as treasury
stock.

      3.3 Equity Interests.  The Companies do not have a material equity
interest in any other "Person" (as defined in Section 15).

      3.4 No Violation.  The execution, delivery and performance of this
Agreement by the Stockholders are not contrary to the Articles of Incorporation
or Bylaws of either Company and will not result in a violation or breach of any
term or provision or constitute a default or give any party a right to
accelerate the due date of any indebtedness under any indenture, mortgage, deed
of trust or other material contract or agreement to which either Company, the
Stockholders or any of them are a party or by which any of them are bound.

      3.5 Financial Statements.  The compiled balance sheets of each Company as
of December 31, 1994, December 31, 1995 and December 31, 1996, and the related
compiled statements of income, stockholders' equity and cash flows for the years
ended December 31, 1994, December 31, 1995 and December 31, 1996, accompanied by
the reports and opinions of Cook Shaver Parker & Williams, independent certified
public accountants, and the unaudited balance sheet of each Company as of May
31, 1997, and the related statement of income for the five month period ended on
said date, certified by the principal financial officer of each Company, subject
to year-end

                                      -3-

(collectively the "Company Financial Statements"), were prepared in accordance
with the books and records of such Company in accordance with generally accepted
accounting principles (except for the absence of statements of stockholders'
equity and cash flows and footnotes from the May 31, 1997, financial statements)
consistently applied throughout the periods involved (except as otherwise noted
therein) and present fairly the financial position, results of operations and
cash flows of each Company for and as of the end of each of such periods.

          3.6 Properties.  The Companies have good title to the assets and
properties shown in the Company Financial Statements or acquired since the date
of the latest balance sheet included therein, except as since sold or otherwise
disposed of in the ordinary course of business.  Such title is free and clear of
all liens, charges, security interests, encumbrances, leases, covenants,
conditions and restrictions other than "Permitted Liens" (as defined in Section
15).  The plants, structures, leasehold improvements, machinery, equipment,
furniture and other tangible assets owned or leased by the Companies are in good
operating condition and repair, subject only to ordinary wear and tear, taking
into account the respective ages of the assets involved, and constitute all the
fixed tangible assets necessary for the operation of the businesses of the
Companies in accordance with their current methods of operation in all material
respects.

          3.7.2 All Material Contracts are valid and binding obligations of the
contracting Company listed in the Disclosure Letter and, to the "best of the
knowledge of the Stockholders" (as defined in Section 15), the other parties
thereto in accordance with their respective terms, subject to the "Bankruptcy
Exception" (as defined in Section 15); there have been no amendments to or
modifications to any Material Contract (except as set forth in the copies
furnished to Newpark); no event has occurred which is, or, following any grace
period or required notice, would become a material default by such Company under
the terms of any Material Contract; except to the extent specifically reserved
against on the latest balance sheet included in the Company Financial
Statements, neither Company is a party to any Material Contract on which the
Stockholders anticipate expenses materially in excess of revenues or which is
otherwise onerous or materially adverse; and neither Company has expressly
waived any material rights under any Material Contract.

complete schedule of all notes payable and other indebtedness for borrowed money
owed by each Company, including a description of the material terms thereof and
a description of all properties or assets pledged, mortgaged or otherwise

      3.9 Absence of Undisclosed Liabilities.  Except as disclosed in the
Disclosure Letter and except for liabilities and obligations reflected on the
latest balance sheet included in the Company Financial Statements or arising in
the ordinary course of business since the date of such balance sheet, none of
which latter items, individually or in the aggregate, have a Materially Adverse
Effect: (a) the Companies do not have, and none of their properties are subject
to, any debts, liabilities or obligations of any nature, whether accrued,
absolute, contingent or otherwise, which are of a type which are required to be
shown or reflected on financial statements prepared in a manner consistent with
generally accepted accounting principles; and (b) to the best of the knowledge
of the Stockholders, the Companies do not have, and none of their properties are

Company) pending or, to the knowledge of the Stockholders, threatened against or
affecting either Company, at law or in equity or before or by any "Government
Body" (as defined in Section 15) or before any arbitrator of any kind.  To the

respect to any judgment, order, writ, injunction, decree, award of any
Government Body.

Stockholders, any previous owner, lessee, tenant, occupant or user of any real
property owned or leased on or prior to the date hereof by the Companies (such
real property and any and all buildings and other improvements thereon being
herein referred to as the "Property") used, generated,

                                      -5-
<PAGE>
 
manufactured, treated, handled, refined, processed, released, discharged, stored
or disposed of any "Hazardous Materials" (as defined in Section 15) on, under,
in or about the Property, or transported any Hazardous Materials to or from the
Property in violation of any "Hazardous Materials Laws" (as defined in Section
15) in a manner or to an extent that resulted or is reasonably likely to result
in a Material Adverse Effect. To the best of the knowledge of the Stockholders,
no underground tanks or underground deposits or Hazardous Materials, the
existence of which would have a Material Adverse Effect, existed on, under, in
or about any Property previously owned or leased by the Companies on or prior to
the date that fee or leasehold title to such Property was transferred to a third
party by the Companies. To the best of the knowledge of the Stockholders, no
underground tanks or underground deposits or Hazardous Materials the existence
of which would have a Material Adverse Effect exist on, under, in or about any
Property that is currently owned or leased by the Companies.

          3.11.2 While any Property was owned or leased by the Companies, they
did not violate to an extent that would have a Material Adverse Effect any
applicable federal, state and local laws, ordinances or regulations, now or

or Hazardous Materials on, under, in or about such Property (including without
limitation the Hazardous Materials Laws).

          3.11.3 As of the date hereof, to the best of the knowledge of the
Stockholders, there are no (1) enforcement, clean-up, removal, mitigation or

Person or Government Body relating to the Property against the Companies or any
Property presently owned or leased by the Companies or relating to damage,
contribution, cost recovery, compensation, loss or injury resulting from any
Hazardous Materials or (3) any occurrence or condition known to the Stockholders
on any Property that is currently owned or leased by the Companies that can
reasonably be expected to subject the Companies or such Property to any material
restrictions on occupancy, transferability or use of any Property under any
Hazardous Materials Laws.  The Disclosure Letter includes a list of all
complaints, notices of violation and claims relating to Hazardous Materials Laws
which, to the knowledge of the Stockholders, have been received by or asserted

income Taxes required to be paid by them with respect to all items of income,
net of all deductions, allocable to them for federal income tax purposes by
reason of

Bockmon Louisiana's status as an S corporation, for each taxable year ended on

unemployment insurance or workers compensation laws and all sales or use Taxes
which are due or payable by the Companies have been paid in full. The Companies
have withheld and paid to, or will cause to be paid to, the appropriate taxing
authorities all amounts required to be withheld from the wages of their
employees under state law and the applicable Code provisions.

          3.12.3 The Stockholders have furnished to Newpark true and complete
copies of the federal income Tax Returns and comparable state Tax Returns of the
Companies covering the years ended December 31, 1994, December 31, 1995 and

material respects of the Tax liabilities of the Companies for the relevant
periods stated therein and accurately setting forth all relevant material items,

enable them to conduct their businesses in all material respects as conducted on
the date hereof, and the Companies are in compliance in all material respects
with all applicable federal, state and local laws, rules, regulations and orders
relating to their businesses, except where failure to have any such license,
franchise, permit or authorization or failure to comply with any such laws,
rules, regulations and orders would not have a Material Adverse Effect.  The
execution and performance of this Agreement and the consummation of the
transactions contemplated hereby will not cause the termination or suspension of
any license, franchise, permit or governmental authorization or violate any
provision of or constitute a default under any law, rule or regulation, order,
writ, injunction or decree of any Government Body applicable to the Stockholders
or the Companies, where such violation or default would have a Material Adverse
Effect.

     3.14 No Labor Problems.  The Companies have not been charged with any
unresolved unfair labor practices and there are no material controversies
pending or threatened between the Companies and any of their employees.  The
Companies have complied in all material respects with all laws relating to
wages, hours, collective bargaining and similar employment matters the
noncompliance with which would have a Material Adverse Effect, and the Companies
have paid all social security and similar Taxes that are due and payable and are
not liable for any arrears or wages or any Taxes or material penalties for
failure to comply with any of the foregoing.

Stockholders and their Family Members.

     3.18 Indebtedness with Insiders.  Except for accrued salaries for one

a condition precedent to Newpark's obligations to consummate the Exchange and
issue the Newpark Shares):

     3.25 Investment Representations.   Either such Stockholder is an
"accredited investor", as that term is defined in Rule 501 of the Rules and
Regulations, or such Stockholder, either alone or with such Stockholder's
qualified "purchaser representative" (as defined in Rule 501 of the Rules and
Regulations), has such knowledge and experience in financial and business
matters that he is capable of evaluating the risks and merits of an investment
in Newpark Common Stock.  Such Stockholder is acquiring his Newpark Shares in
the Exchange for investment and not with a view to the sale thereof other than
in compliance with the requirements of the Securities Act and applicable Blue
Sky laws.   At the request of Newpark, each Stockholder will furnish to Newpark
evidence reasonably satisfactory to Newpark that the foregoing representations
are true.  Such Stockholder acknowledges that Newpark has made available to him
the opportunity to ask questions and receive answers concerning the terms and
conditions of the Exchange and to obtain any additional information that Newpark
is required to furnish under Regulation D of the Rules and Regulations.

     3.26 Enforceability.  This Agreement has been duly and validly executed by
such Stockholder, and this Agreement constitutes a legal, valid, and binding
obligation of such Stockholder, enforceable against him in accordance with its
terms, subject to the Bankruptcy Exception.  Such Stockholder has the requisite
power to enter into this Agreement and perform his obligations hereunder
(including without limitation to sell and deliver his Target Shares), and no
other Person's joinder as a party hereto is necessary therefor pursuant to any
community property laws or otherwise, and there is no restriction on the power
of the Stockholder to sell and deliver his Target Shares pursuant to any trust,
estate planning or other similar document or any prenuptial or post-nuptial
agreement or arrangement.

                                      -11-
<PAGE>
 
     3.27 No Litigation.  There are no actions pending or, to the knowledge of
the Stockholders, threatened in any court or arbitration forum or by or before
any Government Body involving the Companies or such Stockholder relating to or
affecting any of the transactions contemplated by this Agreement.

     3.28 Title to Shares.  Such Stockholder is the holder of record and owns
beneficially that number of Target Shares set forth opposite his name in the
Disclosure Letter and owns such Target Shares free and clear of all liens,
security interests, encumbrances and restrictions, other than restrictions
contemplated by this Agreement.  Such Stockholder is not a party to any voting
trust, proxy or other agreement with respect to the voting of any of his Target
Shares.

the Exchange):

     4.1 Organization and Good Standing.

         4.1.1. Newpark is a corporation duly organized, validly existing and in
good standing under the laws of the State of Delaware. Newpark has corporate
power and authority to carry on its business as presently conducted and is
qualified to do business in every jurisdiction in which the character and
location of the assets owned by it or the nature of the business transacted by
it or both require qualification and failure to be so qualified would have a
Material Adverse Effect.

         4.1.2. Newpark has furnished to the Stockholders complete and correct
copies of Newpark's Certificate of Incorporation and Bylaws as in effect on the
date hereof.

     4.2 Capital Stock.  The authorized capital stock of Newpark consists of
80,000,000 shares of Common Stock, $.01 par value, of which 31,367,874 shares
were issued and outstanding on June 30, 1997, and 1,000,000 shares of Preferred
Stock, $.01 par value, of which no shares are issued and outstanding.

     4.3 Newpark Subsidiaries.  Each subsidiary of Newpark that is a
"significant subsidiary," as defined in Rule 1-02(w) of Regulation S-X of the
Rules and Regulations (each a "Newpark Subsidiary" and collectively the "Newpark
Subsidiaries), is duly organized and in good standing under the laws of the
jurisdiction in which it was incorporated or organized, has full corporate power
and authority to carry on its business as now conducted by it and is entitled to
own or lease and operate its properties and assets now owned or leased and
operated by it.  Each Newpark Subsidiary is duly qualified and in good standing
as a foreign corporation or other entity in each jurisdiction where the
character or location of the assets owned by it or the nature of the business
transacted by it require such qualification, except where failure to be so
qualified would not have a Material Adverse Effect.

and the consummation of the transactions contemplated hereby have been duly
authorized by the Board

                                      -12-
<PAGE>
 
of Directors of Newpark. This Agreement has been duly executed and delivered to
the Stockholders and no vote of the stockholders of Newpark or further corporate
action is necessary on the part of Newpark to make this Agreement valid and
binding upon Newpark in accordance with its terms, subject to the Bankruptcy
Exception. The execution, delivery and performance of this Agreement by Newpark
are not contrary to the Certificate of Incorporation or Bylaws of Newpark and
will not result in a violation or breach of any term or provision or constitute
a default or give any party a right to accelerate the due date of any
indebtedness under any indenture, mortgage, deed of trust or other contract or
agreement to which Newpark is a party or by which Newpark is bound.

     4.5 Newpark Reports.  Newpark has delivered to the Stockholders copies of
Newpark's Annual Reports on Form 10-K for the years ended December 31, 1994,
1995 and 1996 (as amended), Newpark's Quarterly Report on Form 10-Q for the

April 4, 1997, for its Annual Meeting of Stockholders held on May 14, 1997.  All
of said documents and all periodic reports filed by Newpark with the Commission
after the date hereof are called the "Newpark Reports" herein.  The Newpark
Reports have been or will be duly and timely filed with the Commission and are
or will be when filed in compliance with the Rules and Regulations.  As of their
respective dates, none of the Newpark Reports contained or will contain any
untrue statement of a material fact or omitted or will omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.

date hereof have been prepared in accordance with the books and records of
Newpark and its subsidiaries and in accordance with generally accepted
accounting principles consistently applied during the periods indicated, all as
more particularly set forth in such financial statements and the Notes thereto.
Each of the balance sheets included in the Newpark Financial Statements presents
fairly as of its date the consolidated financial condition and assets and
liabilities of Newpark and its subsidiaries.  Except as and to the extent
reflected or reserved against in such balance sheets (including the Notes
thereto), Newpark (including its subsidiaries) did not have, as of the dates of
such balance sheets, any material liabilities or obligations (absolute or
contingent) of a nature customarily reflected in a balance sheet or the notes
thereto prepared in accordance with generally accepted accounting principles.
The consolidated statements of earnings and stockholders' equity and
consolidated statements of changes in financial position included in the Newpark
Financial Statements present fairly the results of operations and changes in
financial position of Newpark and its subsidiaries for the periods indicated.

     4.7 Absence of Certain Changes.  Since March 31, 1997, there has not been
any material adverse change in the results of operations, financial condition,
liquidity, assets, properties or business of Newpark and its subsidiaries, taken
as a whole.

                                      -16-
<PAGE>
 
the date hereof, which adjustment, question, claim, assessment or dispute could,
if pursued successfully, result in or give rise to a claim against the
Stockholders under this Agreement (a "Tax Claim"), Newpark shall promptly inform
the Stockholders in writing of such Tax Claim. The provisions of Section 10
shall apply to the handling of any Tax Claim.

          9.3.2 Current Tax Returns. The Stockholders shall be responsible for
the preparation of all Tax Returns of the Companies for all taxable periods that

(taking into account all extensions) on or before the date hereof. Newpark will
make available to the Stockholders, without charge, the services of its
personnel and the personnel of the Companies to assist the Stockholders in the

ending on or before the date hereof shall be for the account of Bockmon, and any
refunds and credits against federal income Taxes paid by the Stockholders with
respect to Bockmon (together in each case with any interest received or credited
on or with respect to such refund or credit) attributable to any taxable period
or portion thereof ending on or before the date hereof shall be for the account
of the Stockholders; any refunds or credits of other Taxes attributable to any
taxable period ending on or before the date hereof for either Bockmon or Bockmon
Louisiana shall be for the account of such Company.  To the extent that any such
refund, credit or interest thereon exceeds the amount of such refund, credit or
interest, if any, accrued on the books of the Companies as of the Effective
Time, the Stockholders shall receive credit in an amount equal to the amount of
such excess against any liability they may have under Section 10.

          9.3.4 Cooperation. Newpark and the Stockholders shall cooperate in
good faith with each other in a timely manner in the preparation and filing of

matters solely involving Newpark and its Subsidiaries other than the Companies.
Each party shall execute and deliver such powers of attorney and make available
such other documents and such personnel as are necessary to carry out the intent
of this Section 9.3.4. Each party agrees to promptly notify the other parties of

documents, accounting data and other information (including computer data)
necessary for the preparation and filing of all Tax Returns of the Companies and

their terms all indebtedness of the Companies as to which the Stockholders have
executed personal guarantees, as disclosed in the Disclosure Letter.

      10.1 Indemnification by the Stockholders.  Subject to the provisions of
Sections 8 and 10.3, the Stockholders, jointly and severally, hereby agree to
indemnify, defend, protect and hold harmless Newpark against all damages,
losses, liabilities, costs and expenses (including reasonable attorneys' fees)
resulting from (i) any breach of any warranty or representation made by them
under or in connection with this Agreement and (ii) the presence on, under, in
or about the Property of any Hazardous Materials as of the Effective Time or the
noncompliance by the Company with any Hazardous Materials Laws on or before the
Effective Time, whether or not disclosed in the Disclosure Letter.  Such
indemnification shall be solely the responsibility of the Stockholders, and they
shall not have any right to recover any portion of their liability from the
Companies, whether by right of indemnification, contribution or otherwise.

      10.2 Indemnification by Newpark.  Subject to the provisions of Sections 8
and 10.3, Newpark hereby agrees to indemnify, defend, protect and hold harmless
Stockholders against all damages, losses, liabilities, costs and expenses

or representation made by Newpark under or in connection with this Agreement.
The rights to such indemnification shall accrue solely to Stockholders, and the
Companies shall have no interest therein.

      10.3 Indemnification Procedures and Limitations.  The following provisions
shall apply to all indemnification and hold harmless provisions of this
Agreement:

           10.3.1 No party shall be required to indemnify another pursuant
hereto unless the party seeking indemnification (the "Indemnitee") shall, with
reasonable promptness, provide the other party (the "Indemnitor") with copies of
any claims or other documents received and shall otherwise make available to the
Indemnitor all material relevant information. The Indemnitor shall have the
right to defend any such claim at its expense, with counsel of its choosing, and
the Indemnitee shall have the right, at its expense, using counsel of its
choosing, to join in the defense of any such claim. The Indemnitee's failure to
give prompt notice or to provide copies of documents or to furnish relevant data
shall not constitute a defense in whole or in part to any claim by the
Indemnitee against the Indemnitor except to the extent that such failure by the
Indemnitee shall result in a material prejudice to the Indemnitor.

                                      -18-
<PAGE>
 
          10.3.2 Except as hereinafter provided, neither party shall settle or
compromise any such claim unless it shall first obtain the written consent of
the other, which shall not be unreasonably withheld.  The foregoing
notwithstanding, if suit shall have been instituted against the Indemnitee and
the Indemnitor shall have failed, after the lapse of a reasonable time after
written notice to it of such suit, to take action to defend the same, the
Indemnitee shall have the right to defend the claim (without limiting the right
of the Indemnitor to participate in the defense) and to charge the Indemnitor
with the reasonable cost of any such defense, including reasonable attorneys'
fees, and the Indemnitee shall have the right, after notifying but without
consulting the Indemnitor, to settle or compromise such claim on any terms
reasonably approved by the Indemnitee.

          10.3.3 Neither Newpark nor the Stockholders shall have any liability
for breach of warranty or representation hereunder except to the extent that the
amount of all valid claims for breach of warranty or representation against it
or them hereunder exceeds an aggregate of $25,000. In no event shall the
liability of any of the Stockholders for any breach of warranty or
representation hereunder exceed the value of the Newpark Shares for which his
Target Shares are exchanged in the Exchange, for which purpose they shall be
valued at their Closing Value. To the fullest extent permitted by law,
Stockholders shall satisfy their liability hereunder by delivering to Newpark
some or all of such Newpark Shares, valued at their Closing Value, and Newpark
shall satisfy its liability by issuing additional Newpark Shares valued at their
Closing Value. Nothing contained herein shall relieve any of the Stockholders or
Newpark of any liability he or it may have for any intentional breach of
representation or warranty or for breach of any covenants or agreements made
herein by such party.

          10.3.4 In determining the amount of any damage, loss, liability, cost
or expense suffered by Newpark which gives rise to liability of Stockholders
hereunder, there shall be taken into account the amount of any Tax benefits
actually realized by Newpark and its subsidiaries attributable to such damage,
loss, liability, cost or expense or derived therefrom in the same or any past or
subsequent taxable period, also taking into account the Tax treatment of the
receipt by Newpark of any payment from Stockholders.

     10.4 Dispute Resolution; Arbitration.  The parties desire to finally
resolve any and all issues and disputes arising out of or related to this
Agreement or its alleged breach as promptly as practicable and, in any event,
within the survival period specified in Section 8.  Newpark and the Stockholders
shall first attempt diligently to resolve any such issue or dispute.  They may,
if they desire, attempt to mediate the dispute and shall, if they choose, do so
in accordance with the Commercial Mediation Rules of the American Arbitration
Association ("AAA"), either as written or as modified by mutual agreement.  A
written agreement to undertake mediation may be made at any time.  If
arbitration proceedings have been instituted, they shall be stayed until the
mediation process is terminated.  Any dispute arising out of or related to this
Agreement or its alleged breach that cannot be resolved by mutual agreement
(including mutually agreed mediation) shall be resolved exclusively by final and
binding arbitration, conducted as expeditiously as possible in the City of
Houston, Texas, in accordance with the Commercial Arbitration Rules of the
American Arbitration Association.  The decision of the arbitrator or arbitrators
shall be final, conclusive and binding on all parties.  The arbitrators shall
prepare an award in writing which reflects the final decision of the

                                      -19-
<PAGE>
 
arbitrators and a copy of such award shall be delivered to each party to the
arbitration. Judicial confirmation of the decision of the arbitrators shall be
sought only in the Judicial District Court of Harris County, Houston Division.

  11. Destruction of Assets.  All risk of loss with respect to the assets
and businesses of the Companies shall be borne by the Stockholders until the
Closing to the extent set forth in this Section 11.  If on the date hereof any
assets of the Companies shall have suffered loss or damage on account of fire,
flood, accident, act of war, civil commotion, or any other cause or event beyond
the reasonable power and control of the Companies (whether or not similar to the
foregoing) to an extent which materially affects the value to Newpark of the
Target Shares, Newpark shall have the right at its election to complete the
Exchange (in which event, as Newpark's sole and exclusive remedy with respect to
the consequences of such loss or damage, all claims of the Companies with
respect to such loss or damage and all insurance proceeds arising therefrom
shall be for the account of the Companies), or, if it does not so elect, it
shall have the right, which shall be in lieu of any other right or remedy
whatsoever, to terminate this Agreement.  In the latter event, all parties shall
be released from liability hereunder.

stock exchange or are quoted on Nasdaq.

          3.  Confidentiality.  Covenantor shall keep secret and retain in
confidence, and shall not use for the benefit of Covenantor or others, any
confidential information concerning the business of either of the Companies or

          4.  Term.  The term of this Agreement commences on the date hereof and
shall continue for a period of sixty months.  Covenantor hereby acknowledges the
receipt and sufficiency of full consideration for this Agreement.

          5.  Injunctive Relief.  Covenantor hereby stipulates and agrees that
any breach by him of this Agreement cannot be reasonably or adequately
compensated by damages in an action at law and that, in the event of such
breach, Newpark shall be entitled to injunctive relief, which may include but
shall not be limited to restraining Covenantor from engaging in any activity
that would constitute a breach of this Agreement.

          6.  Severability.  Covenantor acknowledges that he has carefully read
and considered the provisions of Paragraphs 1 through 4 of this Agreement and,
having done so, agrees that the restrictions set forth therein (including but
not limited to the time periods of restriction and the geographical areas of
restriction) are fair and reasonable and are reasonably required to protect the
interests of Newpark and its stockholders.  If, notwithstanding the foregoing,
any of the provisions of Paragraphs 1 through 4 shall be held to be invalid or
unenforceable, the remaining provisions thereof shall nevertheless continue to
be valid and enforceable, as though the invalid or

                                       2
<PAGE>
 
unenforceable parts had not been included therein.  If any provision of
Paragraphs 1 through 4 hereof relating to time periods or areas of restriction
or both shall be declared by a court of competent jurisdiction to exceed the
maximum time periods or areas (or both) that such court deems reasonable and
enforceable, said time periods or areas of restriction or both shall be deemed
to become and thereafter shall be the maximum time periods and areas which such
court deems reasonable and enforceable.

          7.  Entire Agreement.  This Agreement constitutes the entire agreement
of Covenantor and Newpark with respect to the subject matter hereof and
supersedes all prior and contemporaneous oral agreements, understandings,
negotiations and discussions of the parties.  No supplement, modification or
waiver of this Agreement shall be binding unless executed in writing by the
party to be bound thereby.  No waiver of any of the provisions of this Agreement
shall be deemed or shall constitute a waiver of any other provision hereof
(whether or not similar), nor shall such waiver constitute a continuing waiver
unless otherwise expressly provided.  Any failure to insist on strict compliance
with any of the terms and conditions of this Agreement shall not be deemed a
waiver of any such terms or conditions.

          8.  Nature of Obligations.  All covenants and obligations of
Covenantor hereunder shall be binding on Covenantor, his assigns, successors and
legal representatives and shall inure to the benefit of Newpark and all of its
Affiliates that engage in any aspect of the Business in any part of the
Territory.

          9.  Law Governing.  The provisions of this Agreement and all rights
and obligations hereunder shall be governed by and construed in accordance with
the internal laws of the State of Texas applicable to contracts made and to be
wholly performed within the State of Texas.

          10.  Attorneys' Fees.  In any litigation relating to this Agreement,
including litigation with respect to any supplement, modification or waiver of
this Agreement or any of its provisions, the prevailing party shall be entitled
to recover its costs and reasonable attorneys' fees.

                              EMPLOYMENT AGREEMENT
                              --------------------


     THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into as of
July 24, 1997, by and between BOCKMON CONSTRUCTION COMPANY, INC., a Texas
corporation ("Employer"), and _______________ ("Employee"), with reference to
the following facts:

     A.  Employee has been employed by Employer as its Vice President.

     B.  On the date of this Agreement, Employer has become a wholly-owned
subsidiary of NEWPARK RESOURCES, INC., a Delaware corporation ("Newpark").
Employer desires to assure itself of the continued services of Employee for a
term expiring no sooner than July 31, 2000, and the parties are entering into
this Agreement for that purpose and in order to set forth the terms of the
employment of Employee.

     NOW, THEREFORE, in consideration of the premises and of the mutual
covenants set forth herein, the parties agree as follows:

     1.  Term of Employment.  Employer hereby continues the employment of
Employee, and Employee hereby accepts continued employment with Employer, for a
period commencing on the date hereof and, except as otherwise provided herein,
expiring July 31, 2000, provided, however, that, each time neither party
terminates this Agreement by written notice given at least sixty (60) days prior
to the expiration of the employment term as last renewed or extended, it shall
be automatically renewed for an additional twelve month period.  As used herein,
the phrase "employment term" refers to the entire period that Employee shall be
employed hereunder, whether for the initial period provided above, or whether
this Agreement is terminated earlier or extended automatically as provided
herein or by mutual agreement between Employer and Employee.  This Agreement
supersedes all agreements and understandings between Employer and Employee
relating to compensation of Employee existing on the date hereof, including but
not limited to salary, commission, bonus and other arrangements, and all such
existing agreements and understandings are hereby terminated.

     2.  Duties of Employee.

         2.1  Employee shall serve as Vice President of Employer and shall do
and perform all services, acts and things necessary or advisable in that
capacity in connection with the conduct of the business of Employer, subject to
the instructions of and policies and limitations set by its Board of Directors.
It is contemplated that Employee's role initially will be substantially the same
as his role with Employer immediately prior to the date hereof.

         2.2  Employee shall devote such productive time, ability and attention
to the business of Employer during the employment term as is reasonably required
for the performance of his duties hereunder.  Employee may devote time and
effort to personal activities to the extent that such activities do not
materially interfere with the performance of his duties hereunder.  If Employer
advises Employee that, in its good faith judgment, such activities are
materially interfering with the
<PAGE>
 
performance of Employee's duties hereunder, Employee will promptly take steps to
appropriately limit such activities.  Subject to the foregoing, Employee shall
not directly or indirectly render any services of a business, commercial or
professional nature to any other person or organization, whether for
compensation or otherwise, without the prior written consent of the Board of
Directors of Employer.

          2.3  Employee agrees to serve without additional compensation, if
elected or appointed thereto, in one or more offices as an officer, director or
member of any committee of the Board of Directors of Employer or of any direct
or indirect subsidiary of Employer.

     3.   Compensation of Employee.

          3.1  As compensation for his services hereunder, Employee shall
receive a salary at the annual rate of $91,000, payable in equal installments on
Employer's regular payroll dates for executive employees.  Employer's Board of
Directors will review Employee's salary annually, and, with the approval of
Newpark's Board of Directors or Compensation Committee, may (but shall be under
no obligation to) increase such salary.

          3.2  For each full or partial fiscal year of Employer during the
employment term, Employer shall pay to Employee, in addition to his salary, a
bonus in such amount, if any, as may be determined by the Board of Directors or
Compensation Committee of Newpark, in its sole discretion.

     4.   Benefits.  Employee shall be entitled to participate in and receive
benefits under all bonus plans, profit-sharing plans, pension plans, group
medical plans and other plans for payment of additional compensation or benefits
to employees of Employer which Employer at any time maintains for executive
employees.  To the extent permitted by law, and provided that such participation
does not result in duplicate payments to Employee, Employee shall also
participate in such benefits plans as Newpark makes available to its executive
employees and the executive employees of its subsidiaries.

     5.  Business Expenses.  Employee is authorized to incur reasonable expenses
for promoting and conducting the business of Employer, including expenditures
for entertainment and travel.  Employer shall reimburse Employee monthly for all
such business expenses upon presentation of reasonable documentation
establishing the amount, date, place and essential character of the
expenditures.

     6.  Disability.

         6.1  If Employee becomes disabled by reason of sickness, physical or
mental disability or any other cause which materially impairs his ability to
perform his duties under this Agreement with reasonable accommodation for a
period of six consecutive months or for nine months in any twelve-month period,
Employer shall have the option to terminate this Agreement effective immediately
by giving written notice of termination to Employee within a reasonable time
following the end of such period of disability.  If Employee becomes temporarily
disabled by reason

                                      -2-
<PAGE>
 
of sickness, physical or mental disability, or any other cause so that he is
unable to perform efficiently his duties hereunder with reasonable
accommodation, he shall be entitled to compensation as provided for herein until
the total period of such temporary disability shall equal an aggregate of three
consecutive months or an aggregate of six months during any period of twelve
consecutive months.  As to any subsequent periods of disability during said
twelve month period, Employee shall not be entitled to compensation.

          6.2  In the event of the termination of this Agreement pursuant to the
provisions of Paragraph 6.1 above, Employee shall be entitled to salary and
discretionary bonus earned by him prior to the date of termination as provided
for in this Agreement computed pro rata up to and including that date; but he
shall not be entitled to compensation after the date of termination.

     7.   Termination of Employment.

          7.1  This Agreement and the employment of Employee hereunder may be
terminated at any time prior to the expiration of the term of this Agreement as
follows:

               7.1.1 By Employer as a result of disability of Employee as
provided in Paragraph 6.1 above, or the death of Employee;

               7.1.2 upon the mutual agreement of the parties;

               7.1.3 by Employer in the event of: (i) conviction of Employee of
a major felony (whether or not committed in the course of his employment) from
which no appeal has been made, or, if an appeal has been made, upon a final
determination adverse to Employee; or (ii) gross misconduct by Employee causing
material harm to Employer, but only if (x) Employee shall not have discontinued
such gross misconduct within ten days after receiving written notice from
Employer that it will consider the continuation of such gross misconduct cause
for termination of this Agreement, or (y) the gross misconduct is of such a
nature that Employer would be materially prejudiced thereby whether or not
Employee discontinues such gross misconduct;

               7.1.4 by Employee if Employer shall fail to cure a material or
default by it under any of the terms of this Agreement within thirty days after
written notice of such breach or default is given by Employee;

               7.1.5 by Employer if Employee shall fail to cure a material
breach or default by him under this Agreement within thirty days after written
notice of such breach or default is given by Employer; and

          7.2  This Agreement shall not be terminated by any merger or
consolidation where Employer is not the consolidated or surviving corporation or
by any transfer of all or substantially all of the assets of Employer.  In the
event of any such merger or consolidation or transfer of assets, the surviving
or resulting corporation or the transferee of the assets of Employer shall be
bound by and shall have the benefit of the provisions of this Agreement; and
Employer shall take all actions necessary to ensure that such corporation or
transferee is bound by the provisions of this Agreement.

                                      -3-
<PAGE>
 
          7.3  Upon termination of this Agreement for any reason whatsoever,
Employee shall return to Employer all automobiles, equipment, books, records,
customer lists, catalogs, invoices, correspondence and other property which was
acquired from or otherwise belongs to Employer, including any property or
documentation developed by Employee in the course of his employment.

     8.   Proprietary Information and Non-Competition.

          8.1  Employee recognizes and acknowledges that the performance of his
services hereunder will necessarily result in disclosure to him of certain trade
secrets and confidential information, including source of supply information,
sales information, customer lists, customer information and pricing, all of
which are special and unique assets and trade secrets of Employer's business.
For the purpose of this Agreement, such information shall be referred to and is
acknowledged as "proprietary information of the Employer."  In view of the
foregoing, in addition to and not in limitation of the provisions of the
Noncompetition Agreement executed concurrently herewith by Newpark and Employee,
Employee agrees that:

               8.1.1  During and after the employment term, Employee will not
disclose or use any proprietary information of Employer, except for the purpose
of carrying out his duties hereunder, unless such use or disclosure is
specifically consented to in writing by Employer.

               8.1.2 For the period of one year after the employment term,
Employee will not in any way, directly or indirectly, for himself or on behalf
of any other person or entity, associate in business as an employer, employee or
otherwise, with any employee, officer or agent of Employer until such person has
terminated employment with Employer for a period of one year.

               8.1.3 During the employment term and thereafter, Employee will
not, directly or indirectly, for himself or on behalf of any other person or
entity, induce or attempt to induce any of Employer's personnel to terminate
their relationship with Employer, nor will Employee induce or attempt to induce
any of Employer's personnel to do anything contrary to the best interests of
Employer.

          8.2 Employee agrees that in the event of any breach by Employee of any
covenant in this Paragraph 8, Employer shall be entitled, in addition to other
remedies, to immediate injunctive relief if necessary to avoid irreparable harm
and injury.

     9.   General Provisions.

          9.1  Any notices to be given hereunder by either party to the other
shall be in writing and may be effected either by personal delivery or by mail,
registered or certified, return receipt requested, postage prepaid.  Mailed
notices shall be addressed to the parties at the addresses appearing opposite
their respective signatures below and shall be deemed effective 24 hours after
being deposited in the U.S. mails, postage prepaid and property addressed.  Each
party may change its address by written notice in accordance with this
Paragraph.

                                      -4-
<PAGE>
 
          9.2  This Agreement supersedes and any and all other agreements,
either oral or in writing, between the parties hereto with respect to the
employment of Employee and contains all of the covenants and agreements between
the parties with respect to such employment.  Each party acknowledges that no
representations, inducements, promises or agreements, oral or otherwise, have
been made by any party, which are not embodied herein, and that no other
agreement, statement or promise not contained in this Agreement shall be valid
or binding.  Any modification of this Agreement will be effective only if it is
in writing signed by the party to be charged.

          9.3  Any paragraph, sentence, phrase, or other provision of this
Agreement which is in conflict with any applicable statute, rule, or other law
shall be deemed, if possible, to be modified or altered to conform thereto or,
if not possible, to be omitted from this Agreement.  The invalidity of any
portion hereof shall not affect the force or effect of the remaining portions
hereof.

          9.4  This Agreement shall be governed by and construed in accordance
with the laws of the State of Texas, and the Judicial District Court of Harris
County, Texas, Houston Division, shall be the only proper forum for disputes
hereunder.

          9.5  The rights and obligations of Employer under this Agreement shall

Employer.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement the day

                         REGISTRATION RIGHTS AGREEMENT
                         -----------------------------


          This Registration Rights Agreement (the "Agreement") dated as of July
24, 1997, is entered into by and between NEWPARK RESOURCES, INC., a Delaware
corporation ("Newpark"), and each of the Persons whose names and addresses are
listed on Exhibit "A" attached to this Agreement (each a "Holder" and
collectively the "Holders"), with reference to the following facts:

          A.   Holders are entitled to receive an aggregate of 251,000 shares
(the "Shares") of Newpark's common stock, $.01 par value (the "Common Stock"),
upon the exchange (the "Exchange") of 100% of the shares of the capital stock of
BOCKMON CONSTRUCTION COMPANY, INC., a Texas corporation, and BOCKMON
CONSTRUCTION COMPANY OF LOUISIANA, INC., a Texas corporation, pursuant to the
Agreement and Plan of Reorganization (the "Exchange Agreement") among Newpark
and the "Stockholders" so identified in the Exchange Agreement (each of whom is
a Holder).  Because the Shares are being issued pursuant to an exemption from
the registration provisions of the Securities Act, resale of the Shares without
registration under the Securities Act is subject to restrictions.

          B.   In order to satisfy a condition precedent to the Exchange, this
Agreement obligates Newpark to use its best efforts to register some of the
Shares under the Securities Act at certain times.

               NOW, THEREFORE, in consideration of the premises set forth above
and the mutual promises and covenants hereinafter set forth, the parties agree
as follows:

          1.   Definitions.  As used in this Agreement, the following
capitalized terms shall have the following respective meanings:

               Common Stock - As defined in Paragraph A above.

               Exchange Act - The Securities Exchange Act of 1934, as amended,
or any similar federal statute then in effect, and a reference to a particular
section thereof shall be deemed to include a reference to the comparable
section, if any, of any such similar federal statute.

               Holder or Holders - As defined in the introduction to this
Agreement.

               Holder Party or Parties - As defined in Paragraph 6.1 below.

               Participating Holder or Holders - Each Holder or all Holders for
whom Shares are included in a registration statement filed under the Securities
Act.

               Person or person - An individual, partnership, joint venture,
corporation, trust, unincorporated organization or government or any department
or agency thereof.

               Registration Expenses - Any and all expenses incident to
performance of or compliance with this Agreement, including, without limitation:
(i) all SEC and stock exchange or National Association of Securities Dealers
registration and filing fees, (ii) all fees and expenses
<PAGE>
 
of complying with securities or blue sky laws (including reasonable fees and
disbursements of counsel for the underwriters in connection with blue sky
qualifications of the Shares), (iii) all printing, messenger and delivery
expenses, (iv) the fees and disbursements of counsel for Newpark and of its
independent public accountants, (v) any fees and disbursements of underwriters
customarily paid by issuers or sellers of securities, including liability
insurance if Newpark so desires, and (vi) the reasonable fees and expenses of
any special experts retained by Newpark in connection with the requested
registration, but excluding underwriting discounts and commissions and transfer
taxes, if any, applicable to Participating Holders' Shares.

               Rule 144 - Rule 144 under the Securities Act, as amended from
time to time, or any successor Rule.

               Rules and Regulations - The rules and regulations promulgated by
the SEC under the Securities Act and the Exchange Act.

               Securities Act - The Securities Act of 1933, as amended, or any
similar federal statute then in effect, and a reference to a particular section
thereof shall be deemed to include a reference to the comparable section, if
any, of any such similar federal statute.

               SEC - The Securities and Exchange Commission or any other federal
agency at the time administering the Securities Act or the Exchange Act.

               Shares - As defined in Paragraph A above.

          2.   Demand Registration Rights.

               (a) Demand by Holders. Subject to the further terms and
conditions of this Agreement and the Exchange Agreement, if, during the period
commencing November 20, 1997 and continuing for 180 days, one or more Holders
request in writing to Newpark that Newpark effect the registration under the
Securities Act of up to twenty-five percent (25%) of the Shares (which request
shall specify the number of Shares intended to be disposed of by each Holder and
the intended method of disposition thereof), Newpark will promptly give notice
of such requested registration to all other Holders and thereafter will use its
best efforts to effect such registration of (i) the Shares which Newpark has
been so requested to register by such Holders and (ii) all other Shares which
Newpark has been requested to register by other Holders by written requests
delivered to Newpark within 20 days after the giving of such written notice by
Newpark (which requests shall specify the intended method of disposition of such
other Holders' Shares), all for disposition in accordance with the intended
methods of disposition stated in the requests of such Holders.

               (b) Priorities in Demand Registrations. Subject to clauses (i)
and (ii) below, Newpark may include in any registration statement filed in
response to Holders' requests other shares of Common Stock for sale by Newpark
or by other stockholders, provided, however, that (i) if such registration
statement relates to an underwritten offering and the managing underwriter or
underwriters advise Newpark in writing that, in its or their opinion, the number
of shares of Common Stock requested to be included in such registration would
have a material adverse effect on such

                                      -2-
<PAGE>
 
offering (including, without limitation, a material decrease in the price at
which such shares can be sold), then the number of shares of Common Stock
included in the offering shall be reduced, and the Shares and the other shares
of Common Stock to be included in the offering shall participate in such
offering as follows:  (x) the Shares to be sold by Holders shall have priority
over all shares of Common Stock to be offered by Newpark and other stockholders
of Newpark, and (y) if shares of Common Stock in excess of Holders' Shares can,
in the good faith judgment of such managing underwriter or underwriters,
successfully be marketed in such offering, such excess shares shall be included
in such offering in such proportions as may be agreed between Newpark and such
other stockholders; and (ii) if such offering is not underwritten, then no other
shares of Common Stock shall be included in such registration statement unless
Holders consent to the inclusion of such shares therein, which consent shall not
be unreasonably withheld.

          (c) Only One Demand Registration.  Holders shall not be entitled to
make a request pursuant to this Paragraph 2 more than one time, provided that
the registration so requested is actually effected and remains in effect in
accordance with Paragraph 5.1(b).

     3.   Incidental Registration Rights.

          (a) Right to Include Shares.  Subject to the further terms and
conditions of this Agreement and the Exchange Agreement, if, at any time after
November 20, 1997, Newpark proposes to register any Common Stock on any form for
the registration of securities under the Securities Act (other than Form S-4 and
Form S-8), Newpark will at such time give prompt written notice to Holders of
its intention to do so and of Holders' rights under this Paragraph 3.  Upon the
written request of any Holders made within 20 days after receipt of any such
notice that up to twenty-five percent (25%) of the Shares be included in such
registration (which request shall specify the number of Shares intended to be
disposed of by each Holder desiring to participate and the intended method of
disposition thereof), Newpark will cause the Shares for which Holders have
requested registration to be included in the registration statement filed with
respect to such registration under the Securities Act, provided that (i) if, at
any time after giving written notice of its intention to register Common Stock
but prior to the effective date of the registration statement filed in
connection with such registration, Newpark shall determine for any reason not to
register such Common Stock, Newpark may, at its election, give written notice of
such determination to Holders, and, thereupon, shall be relieved of its
obligation to register any Shares in such registration, and (ii) if such
registration involves an underwritten offering, Holders must sell their Shares
(if Holders continue to desire such Shares to be registered) to the underwriters
of such offering on the same terms and conditions as apply to Newpark or the
stockholders for whose account securities are to be sold, as the case may be.

          (b) Priorities in Incidental Registrations.  In connection with any
registration pursuant to this Paragraph 3 involving an underwritten offering, if
the managing underwriter or underwriters advise Newpark in writing that, in its
or their opinion, the number of shares of Common Stock requested to be included
in such registration would have a material adverse effect on such offering
(including, without limitation, a material decrease in the price at which such
Common Stock can be sold), then the amount of the Shares included in the
offering shall be reduced, and the Shares and the other shares of Common Stock
to be included in the offering shall participate in such

                                      -3-
<PAGE>
 
offering as follows:  (i) shares of Common Stock to be sold by Newpark shall
have priority over all shares to be sold by stockholders of Newpark, including
Holders, and (ii) to the extent that shares of Common Stock in excess of the
Common Stock to be sold by Newpark can, in the good faith judgment of such
managing underwriter or underwriters, successfully be marketed in such offering,
(x) the Shares to be sold by Holders and shares of Common Stock to be sold by
any other stockholders of Newpark who have the right to registration of their
Common Stock under agreements in existence at the time Newpark gives notice to
Holders pursuant to this Paragraph 3 shall have priority over shares of Common
Stock to be sold by other stockholders of Newpark, subject to reduction prorata
in proportion to the number of shares of Common Stock proposed to be included in
such offering by each Holder and each other stockholder having such registration
rights, and (y) additional shares of Common Stock, if any, shall be included in
such registration in such proportions as may be agreed upon by Newpark and such
other stockholders.

      4.  Additional Provisions.  Notwithstanding the provisions of
Paragraphs 2 and 3 of this Agreement:

          (a) The total number of Shares that Holders are entitled to have
registered by Newpark under the Securities Act pursuant to Paragraph 2(a) and
Paragraph 3(a) combined is twenty-five percent (25%) so that if twenty-five
percent (25%) of the Shares have been effectively registered under the
Securities Act pursuant to Paragraph 2(a), Holders will not be entitled to have
Shares registered pursuant to Paragraph 3(a), and vice versa.  If the aggregate
number of Shares that Holders propose to have registered exceeds twenty-five
percent (25%) of the Shares, the number of Holders' shares eligible to be
registered shall be allocated prorata among Holders in proportion to the number
of Shares owned by each or as they may otherwise agree among themselves.  If the
aggregate number of Shares that Holders propose to have registered in any
registration statement exceeds twenty-five percent (25%) of the Shares after the
allocation called for by the immediately preceding sentence, the number of
Holders' Shares eligible to be included in such registration statement shall be
allocated prorata among requesting Holders in proportion to the number of Shares
proposed by each of them for inclusion in such registration statement or as they
may otherwise agree among themselves.

          (b) Newpark shall not be required to effect or cause the registration
of Shares held by any Holder pursuant to Paragraph 2 or 3 if, within 25 days
after its receipt of a request to register such Shares, Newpark delivers to such
Holder an opinion of counsel in form and substance satisfactory to counsel to
such Holder, that the entire number of Shares proposed to be sold by such Holder
may be sold, in the manner proposed by such Holder, without registration under
the Securities Act, whether pursuant to Rule 144 or otherwise, within a period
ending not more than ninety (90) days after the date of such opinion.

     5.   Registration Procedures.

          5.1       Newpark Obligations.  If and whenever Newpark is required to
effect the registration of any Shares under the Securities Act as provided in
this Agreement, as expeditiously as possible:

                                      -4-
<PAGE>
 
          (a) Newpark will prepare and file with the SEC a registration
statement with respect to such Shares and use its best efforts to cause such
registration statement to become effective as soon thereafter as possible,
provided, that, before filing such registration statement or prospectus or any
amendments or supplements thereto: Newpark will furnish to each Participating
Holder copies of all such documents proposed to be filed, which documents will
be subject to review by such Holders, and Newpark will not file any such
registration statement or prospectus or any amendment or supplement thereto to
which any Participating Holder shall reasonably object; Newpark may assume, for
the purpose of the foregoing proviso, that a Holder has no objection if Newpark
has not received notice from such Holder within five calendar days after
delivery of such documents to Holder or, with respect to any version of or
amendment or supplement to any such registration statement after the first draft
furnished to such Holder, such shorter period as Newpark may reasonably request
when it furnishes such documents to such Holder, if a longer delay would result
in prejudice to the proposed offering.  Newpark will promptly notify the
Participating Holders and confirm such advice in writing, (i) when such
registration statement becomes effective, (ii) when any post-effective amendment
to such registration statement has been filed with the SEC and when it
thereafter becomes effective, (iii) of the issuance by the SEC of any stop order
suspending the effectiveness of such registration statement or the initiation of
any proceedings for that purpose, (iv) of the issuance by any state securities
commission or other regulatory authority of any order suspending the
qualification or the exemption from qualification of any of the Shares under
state securities or blue sky laws or the initiation of any proceedings for that
purpose, and (v) of any request by the SEC for any amendment or supplement to
such registration statement or any prospectus relating thereto or for additional
information.  Newpark will make every reasonable effort to prevent the issuance
of any stop order and, if any stop order is issued, to obtain the lifting
thereof at the earliest possible moment.

          (b) Newpark will prepare and file with the SEC such amendments
(including post-effective amendments) and supplements to such registration
statement and the prospectus used in connection therewith as may be necessary to
keep such registration statement effective for at least six (6) months (or for
such shorter period in which the Participating Holders have sold all of the
Shares included in such registration statement) and to comply with the
provisions of the Securities Act with respect to the disposition of the Shares
covered by such registration statement during such period in accordance with the
intended methods of disposition by Participating Holders set forth in such
registration statement, as so amended, or such prospectus, as so supplemented.

          (c) Newpark will furnish to each Participating Holder one signed copy
of such registration statement as originally filed and each amendment thereto
(without exhibits unless otherwise requested by such Participating Holder) and
such number of copies of such registration statement and of each such amendment
and supplement thereto, such number of copies of the prospectus (as amended or
supplemented) included in such registration statement (including each
preliminary prospectus and summary prospectus), in conformity with the
requirements of the Securities Act, and such other documents as Participating
Holders may reasonably request in order to facilitate the disposition of the
Shares by all Participating Holders.

                                      -5-

          (d) Newpark will use its best efforts to register or qualify such
Shares covered by such registration statement under such securities or blue sky
laws of any State of the United States as the managing underwriter, if any, or
Participating Holders who have Shares included in such registration statement
shall reasonably request, keep such registrations or qualifications in effect
for so long as such registration statement is in effect, and do any and all
other acts and things which may be reasonably necessary or advisable to enable
each Participating Holder and each underwriter, if any, to consummate the
disposition in such jurisdictions of the Shares to be sold by such Participating
Holder, except that Newpark shall not for any such purpose be required to
qualify generally to do business as a foreign corporation in any jurisdiction
where, but for the requirements of this Paragraph 5.1(d), it would not be
obligated to be so qualified, to subject itself to taxation in any such
jurisdiction, or to consent to general service of process in any such
jurisdiction.

          (e)  Newpark will promptly notify each Participating Holder at any
time when a prospectus relating thereto is required to be delivered under the
Securities Act during the period mentioned in Paragraph 5.1(b) and Newpark
becomes aware that the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances existing at
the time it is to be delivered to a purchaser; and promptly prepare and furnish
to each Participating Holder a reasonable number of copies of an amended or
supplemental prospectus as may be necessary so that, as thereafter delivered to
the purchasers of such Shares, such prospectus shall not include an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing.  If a registration statement is not
effective for the full period called for by Paragraph 5.1(b) for the reasons
described above in this Paragraph, then Newpark's obligation to keep such
registration statement effective shall be extended for a period of time equal to
the period of time during which prospectuses were not available so that the
actual period of effectiveness for such registration statement shall equal that
called for in Paragraph 5.1(b).

          (f)  During the period when the prospectus is required to be delivered
under the Securities Act, Newpark will promptly file all documents required to
be filed with the SEC pursuant to Section 13(a), 13(c), 14 or 15(d) of the
Exchange Act and furnish a copy thereof to each Participating Holder promptly
after such document is so filed.

          (g) Newpark will otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC and enter into and perform its
obligations under customary agreements relating to the registration, including
an underwriting agreement in customary form.  If requested by Participating
Holders having Shares included in such registration statement, Newpark will
obtain an opinion letter from Newpark's counsel addressed to all Participating
Holders and any underwriters, each in customary form covering such matters as
may reasonably be requested.

          (h)  Newpark will make available for inspection by Participating
Holders having Shares included in a registration statement, by any underwriter
participating in any disposition to be effected pursuant to such registration
statement and by any attorney, accountant or other agent retained by any such
seller or any such underwriter, in each case upon receipt of an appropriate

                                      -6-
<PAGE>
 
confidentiality agreement, all financial and other records, corporate documents
and properties of Newpark and its subsidiaries, and cause all of Newpark's
officers, directors and employees to supply all information, as may be
reasonably requested by such Participating Holders or any such underwriter,
attorney, accountant or agent in connection with such registration statement.

          5.2 Participating Holder Obligations.

          (a) Each Participating Holder shall furnish Newpark in writing such
information and documents (or true copies of documents) regarding such Holder
and the distribution of his or her Shares as Newpark may reasonably request,
including questionnaires, powers of attorney, indemnities, standstill
agreements, underwriting agreements and other documents required under the terms
of such underwriting agreements.

          (b) Each Participating Holder agrees that, upon receipt of any notice
from Newpark of the happening of any event of the kind described in Paragraph
5.1(e), such Holder will forthwith discontinue disposition of Shares pursuant to
the registration statement covering such Shares until such Holder's receipt of
copies of the supplemented or amended prospectus contemplated by Paragraph
5.1(e), and, if so directed by Newpark, such Holder will deliver to Newpark (at
Newpark's expense) all copies, other than permanent file copies then in such
Holder's possession, of the prospectus covering such Shares current at the time
of receipt of such notice.  In the event Newpark shall give any such notice, the
period mentioned in Paragraph 5.1(b) shall be extended by the number of days
during the period from and including the date of the giving of such notice
pursuant to Paragraph 5.1(e) to and including the date when all Participating
Holders shall have received the copies of the supplemented or amended prospectus
contemplated by Paragraph 5.1(e).

          5.3 Expenses.  Newpark will pay all Registration Expenses in
connection with each registration of Shares pursuant to Paragraphs 2 and 3;
provided, however, that (x) all underwriting discounts and commissions
attributable to the Shares shall be borne by Participating Holders in proportion
to the number of Shares sold by each of them, and (y) any other fees or expenses
incurred by any of the parties, including fees and expenses of attorneys and
accountants, other than those fees described in clause (ii) of the definition of
Registration Expenses, shall be borne by the party that incurred them.

     6.   Indemnification.

          6.1 Indemnification by Newpark. In the event of any registration of
any of the Shares under the Securities Act pursuant to this Agreement, Newpark
will, and it hereby does, indemnify and hold harmless each Participating Holder,
each Person who participates as an underwriter in the offering or sale of such
securities and each other Person, if any, who controls any such underwriter or
Participating Holder within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act, and the agents, employees, officers and
directors of Participating Holders or such underwriter and each such controlling
person (each a "Holder Party" and collectively as the "Holder Parties"), against
any and all losses, claims, damages or liabilities, joint or several, and
expenses (including any amounts paid in any settlement effected with Newpark's
written

                                      -7-
<PAGE>
 
consent) to which any Participating Holder, any such underwriter or controlling
person may become subject under the Securities Act, common law or otherwise,
insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of or are based upon (i) any untrue
statement or alleged untrue statement of any material fact contained in any
registration statement under which such securities were registered under the
Securities Act, any preliminary, final or summary prospectus contained therein,
or any amendment or supplement thereto, or (ii) any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, and Newpark will reimburse Holder
Parties for any legal or any other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, liability,
action or proceeding, provided, that Newpark shall not be liable in any such
case to the extent that any such loss, claim, damage, liability (or action or
proceeding in respect thereof) or expense arises out of or is based upon any
breach by the indemnified person of its obligations under this Agreement,
including, without limitation, those contained in Paragraph 5.2 or any untrue
statement or alleged untrue statement or omission or alleged omission made in
such registration statement or amendment or supplement thereto or in any such
preliminary, final or summary prospectus or amendment or supplement thereto, in
reliance upon and in conformity with information furnished in writing to Newpark
by or on behalf of such Participating Holder, any such underwriter or
controlling Person specifically for use in the preparation thereof; and
provided, further, that Newpark will not be liable to any Person who
participates as an underwriter in the offering or sale of Shares, or to any
other Person who controls such underwriter within the meaning of the Securities
Act and the Exchange Act, under the indemnity agreement in this Paragraph 6.1
with respect to any preliminary prospectus or the final prospectus, or the final
prospectus as amended or supplemented, as the case may be, to the extent that
any such loss, claim, damage or liability of such underwriter or controlling
Person results from the fact that such underwriter sold Shares to a person to
whom there was not sent or given, at or prior to the written confirmation of
such sale, a copy of the final prospectus (including any documents incorporated
by reference therein) or of the final prospectus as then amended or supplemented
(including any documents incorporated by reference therein), whichever is most
recent, if Newpark has previously furnished copies thereof to such underwriter
and such final prospectus, as then amended or supplemented, has corrected any
such misstatement or omission, and if Newpark shall sustain the burden of
proving that the Holder Party sold Shares to the person alleging such loss,
claim, damage or liability without sending or giving, at or prior to the written
confirmation of such sale, a copy of the amended or supplemented registration
statement or prospectus if Newpark had previously furnished copies thereof to
such Holder Party.  Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of any Holder Party and
shall survive the transfer of such securities by each such Person.

          6.2 Indemnification by Participating Holders.  In the event of
any registration of any securities of Newpark under the Securities Act pursuant
to this Agreement, each Participating Holder, severally and not jointly, will,
and each Participating Holder hereby does, indemnify and hold harmless Newpark,
each director of Newpark, each officer of Newpark who shall sign the
registration statement and its controlling Persons, if any, and all other
prospective sellers and their respective directors, officers and controlling
Persons against any and all losses, claims, damages or liabilities, joint or
several, and expenses (including any amounts paid in any settlement effected
with the Participating Holder's written consent) to which such Persons may
become subject under the

                                      -8-
<PAGE>
 
Securities Act, common law or otherwise, to the extent that such losses, claims,
damages or liabilities (or actions or proceedings in respect thereof) arise out
of or are based upon any statement or alleged statement in or omission or
alleged omission from such registration statement, any preliminary, final or
summary prospectus contained therein, or any amendment or supplement, if such
statement or alleged statement or omission or alleged omission was made in
reliance upon and in conformity with information furnished in writing to Newpark
by or on behalf of such Participating Holder for use in the preparation of such
registration statement, preliminary, final or summary prospectus or amendment or
supplement, and such Participating Holder will reimburse Newpark and such other
indemnified persons for any legal or any other expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim,
liability, action or proceeding; provided, however, that the aggregate amount
which any such Participating Holder shall be required to pay pursuant to this
Paragraph 6.2 shall be limited to the dollar amount of proceeds received by such
Participating Holder upon the sale of the Shares (after deducting any
underwriting commissions, discounts and transfer taxes applicable thereto)
pursuant to the registration statement giving rise to such claim.  Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of Newpark or any of the other prospective sellers or any
of their respective directors, officers or controlling Persons and shall survive
the transfer of such securities by the Participating Holder or such seller.

          6.3 Notices of Claims, etc.  Promptly after receipt by an
indemnified party hereunder of written notice of the commencement of any action
or proceeding with respect to which a claim for indemnification may be made
pursuant to this Paragraph 6 such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party, give written notice to the
latter of the commencement of such action, provided that the failure of any
indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under the preceding subdivisions of this
Paragraph 6, except to the extent that the indemnifying party is actually
prejudiced by such failure to give notice.  In case any such action is brought
against an indemnified party, unless in such indemnified party's reasonable
judgment a conflict of interest between such indemnified and indemnifying
parties may exist in respect of such claim, the indemnifying party will be
entitled to participate in and to assume the defense thereof, jointly with any
other indemnifying party similarly notified to the extent that it may wish, with
counsel reasonably satisfactory to such indemnified party, and after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof, the indemnifying party will not be liable to such
indemnified party for any legal or other expenses subsequently incurred by the
latter in connection with the defense thereof.  No indemnifying party will
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such indemnified party of a release from all liability in respect to such
claim or litigation.

          6.4 Other Indemnification.  Indemnification similar to that
specified in the preceding subdivisions of this Paragraph 6 (with appropriate
modifications) shall be given by Newpark to each Participating Holder and each
underwriter of Shares, and by each Participating Holder to Newpark, with respect
to any required registration or other qualification of securities under any
federal or state law or regulation other than the Securities Act.

                                      -9-
<PAGE>
 
          6.5  Contribution.  If the indemnification provided for in Paragraphs
6.1, 6.2 or 6.4 is insufficient to hold harmless an indemnified party or is
unavailable to a party that would have been an indemnified party under any such
Paragraph in respect of any and all losses, claims, damages or liabilities,
joint or several (or actions or proceedings in respect thereof), referred to
therein, then each indemnified party and each party that would have been an
indemnifying party thereunder shall, in lieu of indemnifying such indemnified
party, contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions or proceedings
in respect thereof) in such proportion as is appropriate to reflect the relative
fault of the indemnifying party, on the one hand, and such indemnified party, on
the other, in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities, joint or several (or actions or
proceedings in respect thereof).  The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue
statements of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the indemnifying party or such
indemnified party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
Newpark and Holders agree that it would not be just and equitable if
contribution pursuant to this Paragraph 6.5 were determined by prorata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this Paragraph 6.5.  The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
referred to above in this Paragraph 6.5 shall include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim (which shall be limited as
provided in Paragraph 6.3 hereof if the indemnifying party has assumed the
defense of any such action in accordance with the provisions thereof).  No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation; Notwithstanding
anything in this Paragraph 6.5 to the contrary, no indemnifying party (other
than Newpark) shall be required pursuant to this Paragraph 6.5 to contribute
with respect to any particular offering any amount which exceeds that amount of
the proceeds received by such indemnifying party from the sale of Shares (after
deducting any underwriting commissions, discounts and transfer taxes applicable
thereto) in such offering, less any amounts previously paid by such indemnifying
party pursuant to the provisions of this Paragraph 6 with respect to such
offering.

          7. Rule 144.  Newpark covenants that it will duly and timely file
the reports required to be filed by it under the Securities Act and the Exchange
Act and the rules and regulations adopted by the SEC thereunder to the extent
required from time to time to enable Holders to sell the Shares without
registration under the Securities Act within the limitations of the exemption
provided by Rule 144. None of such reports will contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements therein, in the light of the circumstances
under which they are made, not misleading.  Upon the request of any Holder,
Newpark will deliver to such Holder a written statement as to whether it has
complied with such requirements.

                                      -10-
<PAGE>
 
          8. Miscellaneous.

             8.1 Transfer of Rights Hereunder.  The rights granted to the
Holders under this Agreement may be transferred to any transferee of the Shares
other than a transferee of Shares that have been registered under the Securities
Act, and, from and after any such transfer, the provisions of this Agreement
applicable to Holders shall be applicable to such transferees.  The foregoing
notwithstanding, no transfer of the Shares may be made without registration
under the Securities Act unless and until the transferor delivers to Newpark an
opinion of counsel reasonably satisfactory to Newpark to the effect that such
transfer would not violate the registration provisions of the Securities Act and
any applicable state law.  In connection with the transfer of such Shares,
Newpark may require each certificate representing Shares transferred to bear an
appropriate restrictive legend.  Such restrictive legend may be removed when (i)
a registration statement with respect to the sale of the Shares represented
thereby shall have become effective under the Securities Act, (ii) such Shares
shall have been distributed to the public pursuant to Rule 144 (or any successor
provision) under the Securities Act, or (iii) such Shares shall have been
otherwise transferred, new certificates for them not bearing a legend
restricting further transfer shall have been delivered by Newpark and subsequent
disposition of such Shares shall not require registration or qualification of
them under the Securities Act or any applicable state law.

             8.2 Notices.  Any and all notices, demands, requests or other
communications hereunder shall be in writing and shall be deemed duly given when
personally delivered to or transmitted by overnight express delivery or by
facsimile to and received by the party to whom such notice is intended, or in
lieu of such personal delivery or overnight express delivery or facsimile
transmission, 48 hours after deposit in the United States mail, first-class,
certified or registered, postage prepaid, return receipt requested, addressed to
the applicable party at the address provided below.  The parties may change
their respective addresses for the purpose of this Paragraph 8.2 by giving
notice of such change to the other party in the manner which is provided in this
Paragraph 8.2.

          8.2 Severability.  The provisions of this Agreement are severable,
and, if any one or more provisions may be determined to be judicially
unenforceable, in whole or in part, the remaining provisions, and any partially
unenforceable provisions, to the extent enforceable, shall nevertheless be
binding and enforceable upon the parties hereto.

          8.3 Counterparts.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

          8.4 Headings.  The headings of the sections, subsections and
paragraphs of this Agreement have been added for convenience only and shall not
be deemed to be a part of this Agreement.

          8.5 Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of Texas.

          8.6 Entire Agreement.  All other prior or contemporary
representations, warranties, covenants or agreements, if any, between the
parties hereto, or their representatives, with respect to the subject matter
hereof are superseded by and merged into this Agreement.  This Agreement shall
constitute the entire understanding between the parties with respect hereto.

          IN WITNESS WHEREOF, the undersigned have executed this Agreement
as of the date set forth on the first page hereof.

Newpark Resources, Inc.
3850 Causeway Boulevard
Suite 1770
Metairie, Louisiana 70002

Gentlemen:

          You have advised us that Newpark Resources, Inc., a Delaware
corporation ("Newpark"), is filing with the Securities and Exchange Commission a
Registration Statement on Form S-3 (the "Registration Statement") covering
resales of 125,500 shares of Newpark Common Stock by certain selling
stockholders.  You have asked us to provide our opinion concerning the legality
of the securities to be sold pursuant to the Registration Statement.

          Based upon our examination of the Registration Statement, the
Certificate of Incorporation and Bylaws of Newpark, the proceedings of the Board
of Directors of Newpark and such other documents as we have considered
advisable, we are of the opinion that the 125,500 shares of Newpark Common Stock
to be sold pursuant to the Registration Statement have been duly authorized and
are legally issued, fully paid and non-assessable shares of Newpark Common
Stock.

          We hereby consent to the use of this opinion in connection with the
Registration Statement to be filed by Newpark with the Securities and Exchange
Commission.

                                                  Very truly yours,

                                                  ERVIN, COHEN & JESSUP LLP

INDEPENDENT AUDITORS' CONSENT


We consent to the incorporation by reference in this Registration Statement of 
Newpark Resources, Inc. on Form S-3 of our report dated May 14, 1997, appearing 
in Amendment No. 1 to the Annual Report on Form 10-K/A of Newpark Resources, 
Inc. for the year ended December 31, 1996.
