statements, including the notes thereto, appearing elsewhere or incorporated by
reference in this Prospectus. Unless otherwise indicated, (i) all information

                                  THE COMPANY
 
  Newpark is a leading provider of integrated environmental services to the oil
and gas exploration and production industry in the U.S. Gulf Coast area,
principally in Louisiana and Texas. These services are concentrated in three
key product lines: (i) processing and disposal of nonhazardous oilfield waste
("NOW"); (ii) processing and disposal of similar oilfield waste that is
contaminated with naturally occurring radioactive material ("NORM"); and (iii)
mat rental services in which patented prefabricated wooden mats are used as
temporary worksites in oilfield and other construction applications.
 
  Over the past few years, Newpark has benefited from a stricter regulatory
environment surrounding the exploration for and the production of oil and gas.
In addition, Newpark's primary U.S. Gulf Coast service area is experiencing
increased oil and gas exploration and production activities. Consequently,
Newpark's sales increased to $98 million in 1995, from $56.3 million in 1993,
and net earnings increased to $12.2 million in 1995, compared to $2.4 million
in 1993. Including the Campbell Wells, Ltd., operations to be acquired by
Newpark concurrently with the closing of this Offering, Newpark would have had,
on a pro forma basis, 1995 sales of $116.8 million and 1995 net earnings of
$16.5 million, without taking into account the full benefit of potential cost
savings resulting from the Acquisition.
   
  For the three months ended June 30, 1996, Newpark's sales increased to $26.2
million, from $22.4 million for the three months ended June 30, 1995, an
increase of 17%. Net earnings for the three months ended June 30, 1996
increased to $3.9 million, or $.34 per share on a primary and fully-diluted
basis, from $3.2 million, or $.30 per share, for the corresponding period of
the prior year. In addition, for the six months ended June 30, 1996, Newpark's
sales increased to $52.9 million, from $44.7 million for the six months ended
June 30, 1995, an increase of 18.6%, and its net earnings increased to $7.2
million, or $.65 per share on a primary basis and $.64 per share on a fully-
diluted basis, for the six months ended June 30, 1996, from $5.7 million, or
$.54 per share, for the corresponding period of the prior year.     
 
OILFIELD WASTE DISPOSAL AND OTHER ENVIRONMENTAL SERVICES
 
  Newpark collects, processes and disposes of oilfield waste, primarily NOW and
NORM. Newpark also treats NOW at the well site, remediates waste pits and
provides general oilfield services. In its NOW processing and disposal
business, Newpark processes the majority of the NOW received at its facilities
for injection into environmentally secure geologic formations deep underground
and creates from the remainder a product which is used as intermediate daily
cover material or cell liner and construction material at municipal waste
landfills. Since the fourth quarter of 1994, Newpark has provided processing
and disposal of NOW waste that is contaminated with NORM by processing the
waste into NOW for injection disposal into wells owned by Newpark. On May 21,
1996, Newpark was issued a license from the Texas Railroad Commission
authorizing the direct injection of NORM into disposal wells at Newpark's Big
Hill, Texas, facility. The direct injection of NORM permitted under the new
license expands Newpark's NORM disposal capacity and significantly reduces the
amount of pre-injection processing and chemicals required, thereby reducing
Newpark's cost of disposal. On June 10, 1996, Newpark amended an agreement with
a major oil company to provide for a NORM waste disposal project, which Newpark
estimates will require disposal of more than 200,000 barrels of NORM and
related NOW and generate revenues of approximately $10 million over the first
12 months of the project.
 
                                       4
<PAGE>
 
 
  Newpark also provides industrial waste management, laboratory and consulting
services for the customers of its NOW and NORM services. Newpark's offsite
waste processing operations utilize a combination of proprietary preparation
technology to blend the waste into an injectable slurry and specific
underground geology into which the slurry is injected.
 
MAT RENTAL
 
  Newpark uses a patented interlocking wooden mat system to provide temporary
worksites in unstable soil conditions typically found along the U.S. Gulf
Coast. Prior to 1994, Newpark's mat rental services were provided primarily to
the oil and gas exploration and production industry. In 1994, Newpark began
marketing these temporary worksites to other industries. Increasing
environmental regulation affecting the construction of pipelines, electrical
distribution systems and highways in and through wetlands environments has
provided a substantial new outlet for these services and has broadened the
geographic area served by Newpark to include the coastal areas of the
Southeastern U.S., particularly Florida and Georgia, in addition to the U.S.
Gulf Coast. Mat rental revenue has increased from $11 million in 1990 to $31
million in 1995. In anticipation of increased demand for hardwood lumber used
in construction of its mats, Newpark purchased a sawmill in Batson, Texas, in
October 1992. Newpark has since doubled the capacity of the sawmill and expects
to fully utilize such capacity in serving its mat rental business.
 
  The recent trend toward more strict environmental regulation of both drilling
and production operations conducted by Newpark's customers has resulted in
greater synergy between Newpark's mat rental and general oilfield construction
services and its other environmental services. Newpark offers its services
individually and as an integrated package and provides a comprehensive
combination of on-site waste management and construction services for both the
drilling of new sites and the remediation of existing sites.
 
STRATEGY
 
  Newpark's growth strategy is focused on expanding its NOW and NORM processing
business and its mat rental business. By using proprietary technologies and
know-how in the processing of NOW and NORM and patented prefabricated mats,
Newpark believes it offers superior products and services. In addition, Newpark
believes that expansion opportunities exist in markets outside the U.S. Gulf
Coast, including foreign markets such as Venezuela, where heightened concerns
about environmental issues should increase demand for Newpark's products and
services.
 
  Key elements of Newpark's growth strategy are:
 
  . Expanding its NORM processing business by utilizing the increased
   capacity and reduced cost that can be achieved through the direct
   injection of NORM, as authorized under the terms of Newpark's recently
   awarded direct injection license, to encourage large volume contracts;
 
  . Expanding its NOW and NORM processing capacity, while more efficiently
   handling the large quantities of waste generated from drilling and
   remediation;
 
  . Applying its direct injection technology to other non-hazardous
   industrial waste markets;
 
  . Expanding its mat rental business into other industries and other
   geographic areas, domestically and internationally; and
 
  . Extending its integrated environmental services and providing a
   comprehensive integrated combination of on-site waste management and
   construction services throughout the U.S. Gulf Coast region.
 
  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.

                                THE ACQUISITION
 
  On June 5, 1996, Newpark entered into an Asset Purchase and Lease Agreement
(the "Acquisition Agreement") with Sanifill, Inc. ("Sanifill") and Campbell
Wells, Ltd. ("Campbell Wells"), a wholly owned subsidiary of Sanifill, for the
purchase and lease of certain marine related assets of the NOW service business
of Campbell Wells (the "Acquired Business"), for an aggregate price of $70.5
million (the "Acquisition"). For the year ended December 31, 1995, Campbell
Wells' revenue from the Acquired Business was approximately $19 million.
 
  Upon consummation of the Acquisition, Newpark will assume a NOW Disposal
Agreement (the "Disposal Agreement") with Campbell Wells and Sanifill providing
for the delivery by Newpark of an agreed annual quantity of NOW for disposal at
certain of Campbell Wells' landfarming facilities, none of which are being
acquired by Newpark. Also upon consummation of the Acquisition, Sanifill will
agree, with certain limitations, that it and its affiliates will not compete
with Newpark in the site remediation and closure business or in the collection
and disposal of NOW generated in a marine environment or transported in marine
vessels within the States of Louisiana, Texas, Mississippi and Alabama, and in
the Gulf of Mexico, for a period of five years from the closing of the
Acquisition.
 
  The purchase price for the Acquisition and the related transaction costs will
be financed with the net proceeds of this Offering. The closing of this
Offering will occur concurrently with, and is conditioned upon, the closing of
the Acquisition.
 
  Newpark believes that the Acquisition will provide economies of scale as
Newpark will be able to handle substantially higher volumes of NOW waste
through its facilities. While Newpark is acquiring from Campbell Wells
facilities and equipment used in the collection, transfer and treatment of NOW,
including docks, transfer stations and barges, Newpark intends to consolidate
these facilities and equipment with Newpark's existing or newly expanded
facilities, allowing Newpark to enjoy significant on-going consolidation
benefits. Such consolidation is expected to result in a one-time restructuring
charge against Newpark's third quarter earnings, which charge Newpark currently
estimates to be approximately $2.0 million before taxes.
 
  For further information regarding the Acquisition, see "The Acquisition" and
"Use of Proceeds".

                                 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. This 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 extremely 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. A material decline in oil or natural gas prices or activities could
materially affect the demand for the Company's services and, therefore, the
Company's results of operations and financial condition.
 
IMPACT OF GOVERNMENTAL REGULATIONS
 
  Newpark believes that the demand for its principal environmental services is
directly related to state regulation of NOW and NORM. Any rescission or
relaxation of such regulations, or a failure of governmental authorities to
enforce such regulations, could result in decreased demand for the Company's
services and, therefore, could materially affect the Company's results of
operations and financial condition. Newpark's business may also be adversely
affected by new regulations or changes in other applicable regulations. For
example, in 1993, the Louisiana market for Newpark's pit closure and site
remediation services was drastically curtailed as a result of uncertainty
caused by proposed changes in regulations governing the possession, use,
transfer and disposition of NORM. This uncertainty was resolved by the
adoption of new regulations in January 1995.
 
  NOW is currently exempt from the principal Federal statute governing the
handling and disposal 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 results of
operations and financial condition.
 
LOW BARRIERS TO ENTRY; LOSS OF TECHNOLOGY RIGHTS
 
  Although Newpark has applied for U.S. patents on certain aspects of its
system for processing NOW and NORM, there is no assurance, even if such
patents are granted, that such patents will give Newpark a meaningful
competitive advantage. Barriers to entry by competitors for the Company's
environmental and oilfield services are low. Therefore, competitive products
and services have been and may be successfully developed and marketed by
others. 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.
 
INCREASED 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. Newpark also faces
competition from oil and gas producing customers who are continually
 
                                       9
<PAGE>
 
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 or of third parties
to enter the disposal market could be increased by future technological change
and innovation and limits 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 results of operations and financial condition.
 
FAILURE TO COMPLY WITH GOVERNMENTAL REGULATIONS
 
  Newpark's business is subject to numerous and continually evolving Federal,
state and local laws, regulations and policies that govern environmental
protection, zoning and other matters. 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 it will be deemed to be in compliance in the future.
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 cease operations or conduct site remediation
until a particular problem is remedied, which could have a material adverse
effect on Newpark's results of operations and financial condition.
 
POTENTIAL ENVIRONMENTAL LIABILITY; INSUFFICIENCY OF INSURANCE
 
  Newpark's business exposes it to risks such as the potential for 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 its future
performance 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 results of operations and
financial condition.
 
FAILURE TO INTEGRATE ACQUIRED BUSINESS
 
  The Acquisition is significantly larger than Newpark's previous acquisitions
and significantly increases the size of Newpark's operations. Campbell Wells'
net sales for 1995 from the Acquired Business were approximately $19 million,
and Newpark's net sales for 1995 were approximately $98 million. Successful
integration of the Acquired Business will depend primarily on Newpark's
ability to manage this additional business and eliminate redundancies and
excess costs. Material failure or substantial delay in accomplishing such
integration could have a material adverse effect on Newpark's results of
operations and financial condition.
 
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.
 
 
                                      10
<PAGE>
 
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.
 
                                THE ACQUISITION
 
  On June 5, 1996, Newpark entered into the Acquisition Agreement with
Sanifill and Campbell Wells for the purchase and lease of certain marine
related assets of Campbell Wells' NOW service business, excluding its
landfarming facilities and associated equipment, for an aggregate purchase
price of $70.5 million. Upon consummation of the Acquisition, Newpark will
assume obligations under the Disposal Agreement with Sanifill and Campbell
Wells, providing for the delivery by Newpark for a period of 25 years of an
agreed annual quantity of NOW waste for disposal at certain of Campbell Wells'
landfarming facilities.
 
BUSINESS OF CAMPBELL WELLS
 
  Campbell Wells, a wholly-owned subsidiary of Sanifill, provides NOW
processing and disposal at four landfarming facilities located in Louisiana
(the "Landfarms") and one facility in Zapata County, Texas (the "Zapata
Facility"). Landfarming is a method of remediating NOW in surface-level
treatment cells that generally consists of rinsing out salts, degrading
organic compounds and drying the resultant material to a soil-like form. Since
April 1994, Campbell Wells has operated a NORM processing facility in
Lacassine, Louisiana (the "Lacassine Facility"). As part of its disposal
service, Campbell Wells collects and arranges for the transportation of wastes
from its transfer facilities to its landfarming facilities. Campbell Wells
also disposes of nonhazardous oil and gas related wastes at the Zapata
Facility, and a portion of this facility is utilized to dewater and stabilize
sludges, drilling muds and other liquids into solid waste materials which are
disposed of in disposal cells located on the site. For the year ended December
31, 1995, Campbell Wells' revenue from its NOW and NORM operations was
approximately $31 million, of which approximately $19 million was generated by
the Acquired Business.
 
DESCRIPTION OF ACQUISITION AGREEMENT
 
  Assets to be Purchased. Under the Acquisition Agreement, Newpark will (a)
assume leases (for their remaining useful life) associated with Campbell
Wells' eight marine docks, including docks at three of the Landfarms, and five
transfer stations in the State of Louisiana that are used in the collection,
transfer and treatment of NOW, (b) purchase and lease (for their remaining
useful life) all of Campbell Wells' or Sanifill's interest in (i) all barges
and marine facilities used to transport NOW to the acquired docks and transfer
stations, (ii) all equipment at the acquired docks and transfer stations and
(iii) all pit remediation equipment, computers and related software, licenses
or rights, office equipment, office furniture, goodwill and all other assets
used in the NOW business not specifically excluded under the Acquisition
Agreement. Newpark also will acquire all of the capital stock of a Sanifill
subsidiary that has entered into the Disposal Agreement.
 
  Assets Excluded. Newpark will not be acquiring any interest in any of the
Landfarms or their associated operating equipment, the Lacassine Facility and
its associated assets or the Zapata Facility and its associated assets.
Newpark also will not be acquiring the name "Campbell Wells" or any other
names used by Campbell Wells or Sanifill in connection with the Landfarms, the
Lacassine Facility or the Zapata Facility, although it will be permitted to
purchase all or any such names for nominal consideration at such time as
Campbell Wells and Sanifill discontinue using them.
 
  Purchase Price; Assumption of Liabilities. The aggregate purchase price
under the Acquisition Agreement is $70.5 million, to be paid at the closing of
this Offering. Other than obligations incident to the post-closing performance
under the contracts and agreements to be specifically assumed by Newpark under
the Acquisition
 
                                      11
<PAGE>
 
Agreement, Newpark will not assume any liabilities of Campbell Wells or
Sanifill in the transaction, including any environmental liabilities arising
from the ownership and prior operation of any of the assets to be acquired or
the Landfarms. Sanifill and Campbell Wells have jointly and severally agreed
to fully indemnify Newpark from all liabilities resulting from any claims
based on events that occurred or circumstances that existed on or before the
closing with respect to Campbell Wells' NOW disposal business.
 
  NOW Disposal Agreement. The Disposal Agreement has been executed by a
subsidiary of Sanifill and will be assumed by Newpark concurrently with the
closing of the Acquisition. The Disposal Agreement provides that for each of
the 25 years following the closing, Newpark will deliver to Campbell Wells for
disposal at the Landfarms the lesser of (i) one-third of the barrels of NOW
that Newpark receives for processing and disposal in the States of Louisiana,
Texas, Mississippi and Alabama and in the Gulf of Mexico (the "Territory") and
(ii) 1,850,000 barrels of NOW, in each case excluding saltwater. The number of
barrels of NOW waste that Newpark is required to deliver to the Landfarms in
any year is subject to reduction by a number of barrels determined by dividing
revenues that Sanifill and its affiliates receive from the collection and
disposal of oilfield wastes or site remediation in the Territory by the price
per barrel that Newpark pays for disposal under the Disposal Agreement. No
deduction is made for revenues received by Sanifill and its affiliates from
(i) disposal at any of the Landfarms of NOW that is generated and collected on
land and is delivered to the Landfarms from the generation site by on-land
transportation ("Excluded NOW"), (ii) disposal of NOW at the Zapata Facility
and collection of NOW within a 200-mile radius of the Zapata Facility, and
(iii) disposal of NOW under the Disposal Agreement. Under the Disposal
Agreement, Campbell Wells and Sanifill will jointly and severally fully
indemnify Newpark from any and all liabilities, including environmental
liabilities, in connection with Campbell Wells' and Sanifill's ownership and
operation of the Landfarms, except for liability resulting from the delivery
by Newpark or its customers of waste that does not conform to the
specifications of the Disposal Agreement, which generally permit Newpark and
such customers to deliver only waste that is legally classified as NOW.
Newpark believes that such specifications are consistent with the type of
waste that it is permitted to receive and that it will dispose of at the
Landfarms.
 
  Non-Competition Covenants. Sanifill will agree at the closing of the
Acquisition that for a period of five years from such closing neither it nor
any of its affiliates will engage, directly or indirectly, in the collection
or disposal of NOW or the site remediation and closure business in the
Territory. Campbell Wells will execute a Joinder Agreement by which it will
agree to such restrictions. However, Sanifill and its affiliates will be able
to continue to market and conduct activities related to (i) disposal at any of
the Landfarms of Excluded NOW, (ii) disposal of NOW at the Zapata Facility and
collection of NOW within a 200-mile radius of the Zapata Facility, (iii)
collection and disposal of NOW or other waste at the Lacassine Facility and
(iv) disposal of NOW under the Disposal Agreement. Sanifill and its affiliates
also will be entitled, without violating the Noncompetition Agreement, to
collect or dispose of NORM, which is a type of NOW; however, at present, the
only facility that Sanifill operates that is legally authorized to dispose of
NORM is the Lacassine Facility.
 
  Closing. The Acquisition Agreement provides that the Acquisition will close
concurrent with the completion of this Offering and following the satisfaction
of all conditions precedent. However, either Newpark or Sanifill and Campbell
Wells may terminate the Acquisition Agreement if the Acquisition does not
close by September 10, 1996.
 
  Conditions to Closing. The obligations of Newpark, Sanifill and Campbell
Wells to consummate the Acquisition are conditioned upon the completion of
this Offering and the satisfaction or, where permitted, the waiver of certain
other customary terms and conditions, including (a) the receipt of all
necessary third party consents, including all necessary regulatory approvals;
(b) the accuracy (subject to certain materiality standards) of all
representations and warranties contained in the Acquisition Agreement; and (c)
that no action, suit or other proceeding shall be pending or threatened which,
if unfavorably determined, would prevent the Acquisition or adversely affect
the right of Newpark to acquire or operate the assets being purchased or
leased.
 
NEWPARK'S PLAN FOR COMBINED OPERATIONS
 
  Newpark anticipates that the Acquisition will provide increased efficiencies
and economies of scale associated with handling a larger volume of waste
through its facilities. Newpark plans to combine the service
 
                                      12
<PAGE>
 
capabilities of the Acquired Business with its existing operations to speed
the turnaround of barges and boats at its transfer stations, thus providing
better customer service. Economic efficiencies are expected to result from the
reduction in size of the combined barge fleet operated by Newpark to service
its transfer stations, and from the consolidation of operations at more
efficient transfer stations, permitting Newpark to receive a substantially
higher volume of waste without material additions to existing costs.
Furthermore, Newpark expects that as a result of the Acquisition, access to
Sanifill's disposal facilities under the Disposal Agreement will allow Newpark
to reduce its barge transportation costs and make more efficient use of its
barge fleet, further augmenting its processing capacity. Newpark believes that
its current processing and disposal capacity, combined with access provided to
the landfarm disposal facilities of Sanifill under the Disposal Agreement,
will be adequate to provide for expected future demand for its oilfield waste
disposal and other environmental services. Newpark will nevertheless continue
its strategy of adding injection disposal capacity throughout the U.S. Gulf
Coast region to more efficiently serve its customers. See "Pro Forma Financial
Information".
 
  While Newpark is acquiring from Campbell Wells facilities and equipment used
in the collection, transfer and treatment of NOW, including docks, transfer
stations and barges, Newpark intends to consolidate these facilities and
equipment with Newpark's existing or newly expanded facilities, allowing
Newpark to enjoy significant on-going consolidation benefits. Such
consolidation is expected to result in a one-time restructuring charge against
Newpark's third quarter earnings, which charge Newpark currently estimates to
be approximately $2.0 million before taxes.
 
                   PRICE RANGE OF COMMON STOCK AND DIVIDENDS
 
  Newpark's Common Stock traded on The Nasdaq National Market under the symbol
"NPRS" through December 5, 1995 and commenced trading on the New York Stock

  On December 30, 1995, Newpark paid a 5% stock dividend on the Common Stock
to stockholders of record on November 30, 1995. Newpark has not paid cash
dividends on the Common Stock since March 15, 1983, and does not intend to pay
any cash dividends in the foreseeable future. The Board of Directors currently
intends to retain earnings for use in Newpark's business, including the
expansion of its mat rental business, both in domestic and foreign markets,
and the continued development of injection wells within its waste disposal
business.

                                USE OF PROCEEDS
 
 The net proceeds to be received by Newpark from the sale of the Common Stock
offered hereby are estimated to be approximately $98.7 million ($113.6 million
if the over-allotment option is exercised in full), assuming a public offering
price of $35.00 per share and after deducting estimated underwriting discounts
and offering expenses. Newpark intends to utilize approximately $71.5 million
of the net proceeds to pay the purchase price of the Acquisition and certain
associated transaction costs. Newpark will use the remaining net proceeds,
estimated to be approximately $27.2 million, to repay outstanding indebtedness
under its bank credit agreement, including all of the $17 million outstanding
under its revolving line of credit and $10.2 million under its term loan.
Newpark anticipates that such payment will provide it increased flexibility to
facilitate further development of its injection disposal capacity, both in
oilfield and industrial waste markets, and expansion of its mat rental
business into international markets.
 
  Borrowings under the bank credit agreement have been used to refinance
existing debt and for general working capital purposes and bear interest at
either a specified prime rate or the LIBOR rate, plus a spread which is
determined quarterly based upon the ratio of Newpark's funded debt to cash
flow. The effective interest rate under the bank credit agreement was 7.38% at
June 30, 1996. The revolving line of credit matures on December 31, 1998, and
the term loan is being amortized over a period of five years ending June 29,
2000.
 
  Although Newpark intends to fully repay its outstanding borrowings under its
revolving line of credit and pay down its term loan, it may borrow amounts
under the revolving line of credit and other facilities from time to time in
the future to fund capital requirements. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources".
 
                                CAPITALIZATION
 
  The following table sets forth the consolidated capitalization of Newpark as
of March 31, 1996 and on an as adjusted basis as of March 31, 1996 to reflect
the sale of the 3,000,000 shares of Common Stock offered in this Offering (at
an assumed public offering price of $35.00 per share and after deducting
underwriting discounts and offering expenses) and the application of the net
proceeds therefrom to complete the Acquisition and to repay outstanding
indebtedness. The following table should be read in conjunction with the
Consolidated Financial Statements of Newpark and the Notes thereto included

                        PRO FORMA FINANCIAL INFORMATION
 
  The unaudited consolidated statements of income set forth below present the
combined statements of income of Newpark and the Acquired Business, adjusted
to give effect to the Acquisition, including the completion of this Offering
and the repayment of indebtedness, as if the Acquisition and such repayment
had occurred on January 1, 1995. The unaudited pro forma combined balance
sheet set forth below combines the consolidated historical balance sheets of
Newpark and the Acquired Business as of March 31, 1996, giving effect to the
Acquisition, including the completion of this Offering and the repayment of
indebtedness, as if the Acquisition and such repayment had been consummated on
March 31, 1996. The Pro Forma Financial Information should be read in
conjunction with the accompanying notes and the historical financial
statements and notes thereto of Newpark and the Acquired Business appearing
elsewhere in this Prospectus.
 
  The Acquisition will be accounted for under the purchase method of
accounting. The total purchase price for the Acquisition will be allocated to
tangible and identifiable intangible assets and liabilities based upon
Newpark's preliminary estimates of their fair value with the excess of cost
over net assets acquired allocated to goodwill. Such allocation is subject to
revision when additional information concerning asset and liability valuations
is obtained, in accordance with FAS No. 38, "Accounting for Preacquisition
Contingencies of Purchased Enterprises". In Newpark's opinion, the asset and
liability valuation for the Acquisition will not be materially different from
the pro forma information presented herein, and Newpark is not aware of any
contingencies which may affect the allocation of the purchase price other than
as set forth in the accompanying pro forma combined balance sheet.
 
  For purposes of presenting pro forma results, no changes in revenues and
expenses have been made to reflect the results of any modifications to
operations that might have been made had the Acquisition been consummated on
the assumed effective date of the transaction. The pro forma expenses include
the recurring costs which are directly attributable to the Acquisition, such
as depreciation expense and amortization of goodwill. The Pro Forma Financial
Information does not purport to represent what Newpark's results of operations
or financial position would actually have been had the Acquisition actually
occurred on the dates specified or to project Newpark's results of operations
for any future period.
 
  Management expects to implement net cost reductions which are not reflected
in the accompanying pro forma statements of income. These cost reductions are
related to the consolidation of certain duplicate administrative and personnel
costs. Such pretax savings for the year ended December 31, 1995 and three
months ended March 31, 1996 are estimated to be $3 million and $700,000,
respectively. The effect of these savings would have increased pro forma net
income per share by $.14 and $.03, respectively. These estimated cost savings
constitute a forward looking statement under the Securities Act. The Company's
actual future net income per share could be materially and adversely affected
by certain risks and uncertainties, including those set forth above under
"Risk Factors".
 
  Further, the accompanying pro forma information does not include the full
benefit of potential cost savings related to efficiency of operation expected
by Newpark. However, no assurance can be given as to the ultimate amount, if
any, of net cost savings that will actually be realized.

(a) Reflects adjustment to record the net cost to Newpark associated with the
    disposal of NOW at Campbell Wells' facilities as required under the terms
    of the Disposal Agreement.
(b) Reflects adjustment to record the amortization of intangible assets and
    goodwill arising in connection with the Acquisition. The non-competition
    covenants are amortized over the contractual life of the Disposal
    Agreement, which is 25 years. Intangibles associated with the going
    concern value of the business acquired, its customer list and other
    intangibles are amortized over 35 years.
(c) The allocation of the purchase price includes a liability for the
    estimated costs of immediately closing certain duplicative transfer
    stations and barge operations of the Acquired Business. This adjustment
    provides for a direct effect of this decision by eliminating certain of
    the duplicate operating expenses related to the closed facilities and
    barge operations. These estimated costs constitute forward looking
    statements under the Securities Act. The Company's actual future operating
    results could be materially and adversely affected by certain risks and
    uncertainties, including those set forth above under "Risk Factors--
    Failure to Integrate Acquired Business".
(d) Reflects adjustment to reduce interest expense related to repayment of
    borrowings under Newpark's bank credit facility utilizing the portion of
    the net proceeds of this Offering in excess of the purchase price in the
    Acquisition.
(e) Adjustment to reflect the effect on income tax expense, calculated at
    Newpark's marginal tax rate of 36.5%, on the adjustments reflected on the
    pro forma financial statements.
(f) This pro forma net income amount constitutes a forward looking statement
    under the Securities Act. The Company's actual future net income could be
    materially and adversely affected by certain risks and uncertainties,
    including those set forth above under "Risk Factors--Failure to Integrate
    Acquired Business".

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion of Newpark's financial condition, results of
operations, liquidity and capital resources should be read in conjunction with
the Consolidated Financial Statements and the Notes thereto included elsewhere
in this Prospectus.
 
OVERVIEW
 
  The Baker Hughes Rotary Rig Count has historically been viewed as the most
significant single indicator of oil and gas drilling activity in the domestic
market. In 1993, the United States rig count averaged 754 rigs in operation,
and increased to 774 in 1994. In 1995, the rig count averaged 723, the second
lowest on record since the advent of the indicator in the early 1940's.
 
  Newpark's operations principally occur in the following rig count
measurement areas: (i) South Louisiana Land, (ii) Texas Railroad Commission
Districts 2 and 3, (iii) Louisiana and Texas Inland Waters and (iv) the
Offshore Gulf of Mexico. The rig count trend in the areas that Newpark serves
has tracked these national trends as set forth in the table below:

  Newpark believes that improved natural gas drilling activity, as evidenced by
the rig count in the area it serves, was an important factor which allowed a
trend of increasing prices in its site preparation and mat rental business to
continue through 1994. Newpark believes the decline in the rig count within
Newpark's service area during 1995, which continued in the first quarter of
1996, was primarily the result of low natural gas prices during most of 1995.
As of June 30, 1996, the U.S. rig count was 777, and 213 within Newpark's
service area, which Newpark believes is reflective of the continued increase in
natural gas prices that commenced in November 1995.
 
  Despite the decline in rig activity, the volume of waste received by Newpark
increased at an annual compound rate of 46% from 1993 to 1995, primarily due
to the recovery of the remediation market following implementation of NORM
regulations and new, more stringent regulations governing the discharge of
drilling and production waste in the coastal and inland waters and in the
offshore Gulf of Mexico.

THREE MONTHS ENDED MARCH 31, 1996 COMPARED TO THREE MONTHS ENDED MARCH 31,
1995
 
 Revenues
 
  Total revenues increased to $26.8 million in the three months ended March
31, 1996 from $22.2 million in the three months ended March 31, 1995, an
increase of $4.6 million, or 20.5%. The major components of the increase by
product line included: (i) $1.3 million of increased revenue from wood product
sales due to increased sales of wood chips produced by additional capacity
added during 1995; (ii) an increase of $1.3 million, or 19.1%, in mat rental
revenue due to a 17.7% increase in volume on pricing similar to the 1995
period; (iii) an increase of $971,000, or 32.0%, in general oilfield service
revenue, which resulted primarily from site preparation services related to
the increased volume of mat rental services provided during the period; (iv)
an increase of $442,000 in offsite waste processing revenues derived primarily
from NORM disposal operations; and (v) an increase of $434,000 in onsite
environmental management services related to the increased site remediation
activity in the 1996 period. NORM processing volume during the current period
increased to 37,200 barrels, compared to 12,600 barrels in the 1995 period.
The effect of the volume increase was offset, in part, by a decrease in the
average revenue per barrel, from $111.00 in the 1995 period to $48.00 in the
current quarter. The change in average price reflects the lower level of
radium contamination in waste received from site remediation projects, which
represent a majority of current volume. NOW disposal revenue increased
$57,000, to $6,048,000 in the current quarter, compared to $5,991,000 in the
1995 period. Total volume increased 8%, to 745,000 barrels, compared to
690,000 barrels in the year-ago quarter, but was partially offset by a decline
in the average revenue per barrel to $8.12 in the 1996 quarter, from $8.68 in
the prior period. The decline is due to changes in mix, with lower priced
remediation volume of 123,000 barrels in the 1996 quarter, representing 16.5%
of total volume, compared to 13.0% in the 1995 quarter.
 
 Operating Income
 
  Operating income increased by $2.4 million, or 64.2%, to $6.1 million in the
1996 period, compared to $3.7 million in the prior period. This represents an
improvement in operating margin to 22.8% in the 1996 period, compared to 16.7%
in the 1995 period. Primary components of the increase included $1.9 million
resulting from the increase in the volume of mats rented and approximately
$470,000 increased operating profit from wood product sales.
 
  General and administrative expenses remained relatively unchanged,
decreasing as a proportion of revenue to 2.7%, from 2.9% in the 1995 period,
and increasing in absolute amount by $69,000.
 
 Interest Expense
 
  Interest expense was substantially unchanged at approximately $900,000 for
both periods, although average outstanding borrowings increased approximately
43.9% from the prior period. This resulted from decreased net interest cost
under the current credit agreement, which became effective as of June 29,
1995, and interest capitalization related to construction in progress in the
current quarter.

 Provision for Income Taxes
 
  For the 1996 period, Newpark recorded an income tax provision of $1.9
million, or 36.4% of pre-tax income. The net provision for the 1995 period of
$423,000, equal to a 15% effective rate, was comprised of a provision for
federal income taxes net of the recognition of certain state income tax
carryforwards available to offset estimated future earnings.
 
 Net Income
 
  Net income increased by $826,000, or 33.2%, to $3.3 million in 1996,
compared to $2.5 million in the 1995 period.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
 Revenues
 
  Total revenues increased to $98 million in 1995, from $79.6 million in 1994,
an increase of $18.4 million or 23.0%. The components of the increase by
product line are as follows: (i) offsite waste processing revenues increased
$10.4 million, as NOW revenue increased $5.5 million (due almost exclusively
to additional volume) and NORM processing revenue increased to $6 million on
approximately 70,000 barrels in 1995, from $1.2 million in revenue and 15,000
barrels in 1994; (ii) mat rental revenue increased $7.7 million, or 34%, due
to (a) increased volume installed at similar pricing compared to the prior
year and (b) an increase in revenues from extended rerentals of $3.6 million
resulting from the longer use of sites and the trend toward deeper drilling in
more remote locations, requiring larger sites to accommodate increased
equipment and supplies on the site and resulting in the size of the average
location growing 17% in 1995 as compared to the prior year; (iii) general
oilfield service revenue increased $1.1 million, or 7.9%, primarily as a
result of the increased level of site preparation work incident to the rental
of mats in the oilfield segment of that business; (iv) onsite environmental
management service revenue declined approximately $300,000, or 4%, with the
reduced level of current drilling-related projects more than offsetting
increased activity in the remediation of old sites; and (v) revenue from wood
product sales decreased approximately $500,000, due in part to production
inefficiencies during the start-up of a new processing line and the inclusion
of a large non-recurring order in prior year revenue.
 
 Operating Income from Continuing Operations
 
  Operating income from continuing operations increased by $9.1 million, or
76.4%, to $21 million in the 1995 period, compared to $11.9 million in the
prior year. This represents an improvement in operating margin to 21.4% in
1995, compared to 14.9% in 1994.
 
  Primary components of the increase included: (i) approximately $2.9 million
related to the effect of volume increases in both NOW and NORM processing;
(ii) $3.6 million from increased mat rerentals; (iii) $1.3 million resulting
from the increase in the volume of mats rented, to approximately 200 million
board feet, compared to 157 million in 1994, at similar margins; and (iv) an
approximate $200,000 increase in operating profit on a better gross margin mix
from wood product sales.
 
  The decline of $573,000 in general and administrative expenses primarily
reflects the impact of approximately $600,000 of prior year charges for legal
costs incurred in an appeal of an expropriation matter. Additionally, the
provision for uncollectible accounts was $511,000 less in the 1995 period as
compared to the 1994 period.
 
 Interest Expense
 
  Interest expense increased to $3.7 million in 1995, from $2.7 million in
1994. The increase was the result of an increase in borrowings, proceeds of
which were used to fund continued additions to productive capacity, including
Newpark's waste processing facilities, its prefabricated board road mats and
additions to inventory, primarily at the sawmill facility.
 
                                      23
<PAGE>
 
 Non-Recurring Expense
 
  Results for the current period include $436,000 of non-recurring costs
associated with a proposed merger which was not completed.
 
 Provision for Income Taxes
 
  During 1995, Newpark recorded an income tax provision of $4.8 million, or
28% of pre-tax income. While Newpark's net operating loss carryforwards remain
to be used for income tax return purposes, for financial reporting purposes,
substantially all of the remaining net operating loss and tax credit
carryforwards applicable to federal taxes were recognized in the first half of
the year, which reduced the effective tax rate for that portion of the year.
During 1994, Newpark recorded a tax benefit of $85,000 as a result of the
availability of net operating loss carryforwards.
 
 Net Income
 
  Net income increased by $2.8 million, or 30%, to $12.2 million in 1995,
compared to $9.4 million in 1994.
 
YEAR ENDED DECEMBER 31, 1994 COMPARED TO YEAR ENDED DECEMBER 31, 1993
 
 Revenues
 
  Total revenues increased from $56.3 million in 1993 to $79.6 million in
1994, an increase of $23.3 million, or 41.4%. Components of the increase by
product line included: (i) a $9.4 million increase in offsite waste
processing, composed of (a) an increase of $8.2 million, resulting from a
72.5% increase in the number of barrels of NOW waste received, which grew to
2.3 million in 1994 from 1.3 million in 1993, and (b) $1.2 million from NORM
processing which began in the fourth quarter of 1994; (ii) an increase of $5.2
million of wood product sales revenue due to an increase in the total tonnage
of products sold at similar pricing; (iii) a $3 million increase in onsite
environmental management revenue reflecting the recovery of this market during
1994 once definitive NORM regulations were effected in both Louisiana and
Texas, resulting in a total of 355,000 barrels of remediation waste being
handled in 1994, as compared to only 22,000 in 1993; (iv) a $2 million
increase in mat rental revenue, the net effect of a 29% increase in average
pricing to approximately $93 per thousand board feet installed and a 4%
decline in total volume to 157 million board feet in 1994, compared to 164
million board feet in 1993; and (v) an increase of approximately $2.1 million
in general oilfield service revenue, which primarily reflects the increased
site construction services related to the increased volume of mats installed
on customers' sites. Other revenue included $1.6 million in 1994 from the
lease of the facility formerly operated as a marine repair yard in Houston,
Texas.
 
 Operating Income from Continuing Operations
 
  Operating income from continuing operations increased $7.5 million, from
$4.4 million, or 7.8% of revenue, in 1993, to $11.9 million, or 14.9% of
revenue, in the current period. Factors contributing to the increase included:
(i) a $3.1 million increase in operating income from offsite waste processing,
of which approximately $600,000 relates to the receipt of 14,711 barrels of
NORM waste solely during the fourth quarter of 1994, with the remainder
attributable to increased volume and substantially unchanged profit
contribution per barrel of NOW processed; (ii) $2.7 million from increased mat
rental revenue; (iii) a $2.5 million increase resulting from the increase in
the volume of mats rented; and (iv) a profit of approximately $800,000 (before
related interest expense) from the lease of Newpark's former marine repair
facility. These increases were partially offset by the following: (a) a
$258,000 decrease in operating income from wood products sales due to higher
inventory costs relative to 1993; (b) a $1.1 million increase in general and
administrative expenses; and (c) a $300,000 increase in the provision for
uncollectible accounts and notes receivable.
 
  General and administrative expenses as a proportion of revenue rose to 4.1%
in 1994, from 3.8% in 1993, while rising in total by $1.1 million, to $3.2
million in 1994, from $2.1 million in 1993. The principal items
 
                                      24
<PAGE>
 
associated with the increase included a charge for legal costs of
approximately $600,000 incurred due to the appeal of an expropriation matter
and a $130,000 provision for additional franchise taxes, as a result of a
recently completed audit.
 
 Interest Expense
 
  Interest expense increased $1.4 million, to $2.7 million in 1994, compared
to $1.3 million in 1993, as Newpark added approximately $17.5 million in net
borrowings to finance new and existing facilities and equipment during 1994.
 
 Provision for Income Taxes
 
  During 1994, Newpark recorded a net deferred tax benefit of $200,000 as a
result of recognizing the future benefit of the income tax carryforwards
available to offset the estimated future earnings. See Note F in the Notes to
Consolidated Financial Statements. The net deferred tax benefit was partially
offset by current tax expense of $115,000.
 
 Net Income
 
  Net income increased to $9.4 million in 1994, from $2.4 million in 1993, an
increase of $7 million, or 288%, equal to 29.9% of incremental revenues.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  During 1995 and to date during 1996, Newpark's working capital needs were
met primarily from operating cash flow. Newpark's working capital position
decreased by $1.1 million during the three months ended March 31, 1996 and
increased by $18.5 million during the year ended December 31, 1995.

  Throughout 1995, Newpark invested approximately $18 million to provide
future capacity within key product lines. These improvements included the
addition of two more injection wells and a grinding mill at the Big Hill
facility, construction of a new injection facility (which includes two
injection wells) at the Fannett site, construction of a bulk waste unloading
facility adjacent to Newpark's existing Port Arthur facility, additions to
Newpark's inventory of rental mats in the domestic market and an expansion of
Newpark's rental mat business into Venezuela. As a result of these asset
additions and expansion, long term debt increased to $46.7 million at year
end, representing 36.3% of total long-term capital. A total of $43.4 million
of the debt was funded through a credit facility with three banks, which was
completed during the second quarter of the year.
 
  Newpark's credit facility provides for a total of up to $50 million of term
financing consisting of a $25 million term loan to be amortized over five
years and a $25 million revolving line of credit. At Newpark's option, these
borrowings bear interest at either a specified prime rate or the LIBOR rate,
plus a spread which is determined quarterly based upon the ratio of Newpark's
funded debt to cash flow. The credit agreement requires that Newpark maintain
certain specified financial ratios and comply with other usual and customary
requirements. Newpark was in compliance with all of the covenants in the
credit agreement at March 31, 1996. The term loan was used to refinance
existing debt and is being amortized over a five year term ending June 29,
2000. In March 1996, the term loan was increased to $35 million, and the $10
million increase was used initially to reduce borrowings on the revolving line
of credit portion of the facility. The revolving line of credit matures
December 31, 1998. Availability of borrowings under the line of credit is tied
to the level of Newpark's accounts receivable and certain inventory. At March
31, 1996, $5.8 million of letters of credit were issued and outstanding under
the
 
                                      25
<PAGE>
 
line and an additional $11.6 million had been borrowed and was outstanding
thereunder. Effective April 24, 1996, Newpark replaced $3.8 million of
outstanding letters of credit with a corporate guaranty, leaving $2 million of
letters of credit outstanding.
 
  Net cash provided by operating activities was $4.2 million during the three
months ended March 31, 1996, compared to $1.9 million in the comparable period
of the prior year, an increase of $2.3 million. Approximately $2 million, or
87%, of the improvement was attributable to increased earnings adjusted for
non-cash tax expense and depreciation and amortization. The remainder of the
increase was the net effect of improved receivable turnover, net of reductions
in accounts payable. Net cash provided by operations was supplemented by $2.6
million in additional net borrowings to finance $6.8 million of incremental
capital investment.
 
  Newpark anticipates capital expenditures of approximately $19 million during
the last three quarters of 1996, including: (i) approximately $7 million to
purchase additional mats for its Venezuela joint venture; (ii) approximately
$5 million for other international expansion in its mat business outside of
Venezuela; and (iii) approximately $4 million to acquire and develop
additional injection well sites and acquire associated equipment. Newpark also
is in discussions with its joint venture partners in Venezuela for the
purchase of their interests in such venture and anticipates that approximately
$3 million may be used to acquire such interests during 1996. For 1997,
Newpark anticipates capital expenditures of approximately $27 million,
consisting of: (i) approximately $15 million in its mat rental business,
including international expansion and mat purchases; (ii) approximately $8
million to acquire and develop additional injection well sites, including an
industrial waste injection facility; and (iii) approximately $4 million for
the upgrade and purchase of equipment. After taking into account the repayment
of outstanding indebtedness as described in "Use of Proceeds", Newpark
anticipates that all of its capital expenditure requirements will be satisfied
with borrowings under its credit facilities and with cash flow from
operations.
 
  Newpark presently has no commitments beyond its bank lines of credit by
which it could obtain additional funds for current operations; however, it
regularly evaluates potential borrowing arrangements which may be utilized to
fund future expansion plans. Newpark believes that following the consummation
of the Acquisition (including the completion of this Offering and the
application of the net proceeds as described in "Use of Proceeds"), available
borrowings under its current credit facility and internally generated funds
will be sufficient to support its working capital, capital expenditure and
debt service requirements for the foreseeable future. Except as described in
the preceding paragraph, Newpark is not aware of any material capital
expenditures, significant balloon payments or other payments on long-term
obligations or any other demands or commitments, including off-balance sheet
items, to be incurred beyond the next 12 months.
 
  Inflation has not materially impacted Newpark's revenues or income.
 
 Deferred Tax Asset
 
  Newpark accounts for income taxes in accordance with Statement of Financial
Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes". This
standard requires, among other things, recognition of future tax benefits
measured by enacted tax rates attributable to deductible temporary differences
between the financial statement and income tax basis of assets and liabilities
and to tax net operating loss and credit carryforwards to the extent that
realization of such benefits is more likely than not. Newpark has provided a
valuation allowance ($236,000 at December 31, 1995) for deferred tax assets
which cannot be realized through future reversals of existing taxable
temporary differences. Newpark believes that remaining deferred tax assets
($10,450,000 at December 31, 1995) are realizable through reversals of
existing taxable temporary differences. Newpark will continue to assess the
adequacy of the valuation allowance on a quarterly basis.

OILFIELD WASTE DISPOSAL AND OTHER ENVIRONMENTAL SERVICES
 
  Newpark collects, processes and disposes of oilfield waste, primarily NOW
and NORM. Newpark also treats NOW at the well site, remediates waste pits and
provides general oilfield services. In its NOW processing and disposal
business, Newpark processes the majority of the NOW received at its facilities
for injection into environmentally secure geologic formations deep underground
and creates from the remainder a product which is used as intermediate daily
cover material or cell liner and construction material at municipal waste
landfills. Since the fourth quarter of 1994, Newpark has provided processing
and disposal of NOW waste that is contaminated with NORM by processing the
waste into NOW for injection disposal into wells owned by Newpark. On May 21,
1996, Newpark was issued a license from the Texas Railroad Commission
authorizing the direct injection of NORM into disposal wells at Newpark's Big
Hill, Texas, facility. The direct injection of NORM permitted under the new
license expands Newpark's NORM disposal capacity and significantly reduces the
amount of pre-injection processing and chemicals required, thereby reducing
Newpark's cost of disposal. On June 10, 1996, Newpark amended an agreement
with a major oil company to provide for a NORM waste disposal project, which
Newpark estimates will require disposal of more than 200,000 barrels of NORM
and related NOW and generate revenues of approximately $10 million over the
first 12 months of the project.
 
  Newpark also provides industrial waste management, laboratory and consulting
services for the customers of its NOW and NORM services. Newpark's offsite
waste processing operations utilize a combination of proprietary preparation
technology to blend the waste into an injectable slurry and specific
underground geology into which the slurry is injected.
 
 NOW
 
  Nonhazardous Oilfield Waste, or NOW, is waste generated in the exploration
for or production of oil and gas. These wastes typically contain levels of oil
and grease, salts or chlorides, and heavy metals in excess of concentration
limits defined by state regulators. NOW also includes soils which have become
contaminated by
 
                                      27
<PAGE>
 
these materials. In the environment, oil and grease and chlorides disrupt the
food chain and have been determined by regulatory authorities to be harmful to
plant and animal life, and heavy metals can become concentrated in living
tissues.
 
 NORM
 
  Naturally Occurring Radioactive Material, or NORM, is present throughout the
earth's crust at very low levels. Among the radioactive elements, only Radium
226 and Radium 228 are slightly soluble in water. Because of their solubility,
which can carry them into living plant and animal tissues, these elements
present a hazard. Radium 226 and Radium 228 can be leached out of hydrocarbon
bearing strata deep underground by salt water which is produced with the
hydrocarbons. Radium generally precipitates out of the production stream as it
is drawn to the surface and encounters a pressure or temperature change in the
well tubing or production equipment, forming a rust-like scale. This scale
contains radioactive elements which, over many years, can become concentrated
on tank bottoms or at water discharge points at production facilities. Thus,
NORM waste is NOW that has become contaminated with these radioactive elements
at concentration levels in excess of limits established by state regulatory
authorities.
 
MAT RENTAL
 
  Newpark uses a patented interlocking wooden mat system to provide temporary
worksites in unstable soil conditions typically found along the U.S. Gulf
Coast. Prior to 1994, Newpark's mat rental services were provided primarily to
the oil and gas exploration and production industry. In 1994, Newpark began
marketing these temporary worksites to other industries. Increasing
environmental regulation affecting the construction of pipelines, electrical
distribution systems and highways in and through wetlands environments has
provided a substantial new outlet for these services and has broadened the
geographic areas served by Newpark to include the coastal areas of the
Southeastern U.S., particularly Florida and Georgia, in addition to the U.S.
Gulf Coast. Mat rental revenue has increased from $11 million in 1990 to $31
million in 1995. In anticipation of increased demand for hardwood lumber used
in construction of its mats, Newpark purchased a sawmill in Batson, Texas, in
October 1992. Newpark has since doubled the capacity of the sawmill and
expects to fully utilize such capacity in serving its mat rental business.
 
  The recent trend toward more strict environmental regulation of both
drilling and production operations conducted by Newpark's customers has
resulted in greater synergy between Newpark's mat rental and general oilfield
construction services and its other environmental services. Newpark offers its
services individually and as an integrated package and provides a
comprehensive combination of on-site waste management and construction
services for both the drilling of new sites and the remediation of existing
sites.
 
DEVELOPMENT OF THE BUSINESS
 
  Since 1990, Newpark has concentrated on expanding and further integrating
its environmental service capabilities. Through acquisitions in 1990 and 1991,
Newpark extended its environmental services into the Texas Gulf Coast region.
In May 1991, Newpark expanded its processing capacity by constructing a new
NOW processing facility in Port Arthur, Texas, replacing a smaller facility.
Newpark has further increased capacity through subsequent equipment additions
and improvements in process technology and procedures. Beginning in 1992,
Newpark determined to develop a deep well injection program and, in March
1993, completed its first facility for underground disposal of NOW, at Big
Hill, Texas. During 1994, Newpark obtained a permit to process NORM waste for
disposal, and thus became a participant in the NORM disposal business. During
its first full year of operation, the NORM plant processed 70,000 barrels of
waste, generating revenue of $6 million.
 
  Recent developments include:
 
  .  On June 10, 1996, Newpark amended an agreement with a major oil company
     to provide for a NORM waste disposal project, which Newpark estimates
     will require disposal of more than 200,000 barrels of NORM and related
     NOW and generate revenues of approximately $10 million over the first 12
     months of the project.
 
                                      28
<PAGE>
 
  .  On May 21, 1996, Newpark was awarded a license from the Texas Railroad
     Commission authorizing the direct injection of NORM into disposal wells
     at its Big Hill, Texas facility.
 
  .  The trend toward more stringent regulation of NOW and NORM waste
     continued during 1995. NORM regulations were adopted in several states,
     most importantly New Mexico and Texas. The NORM regulations were revised
     in Louisiana and Mississippi, and draft regulations have been prepared,
     but are not yet proposed, in Oklahoma.
 
  .  The volume of NOW processed by Newpark grew by 25% during 1995, to 2.9
     million barrels, despite a slightly lower rig count. The effect on
     Newpark's services of a small decline in the number of active drilling
     rigs was substantially offset by deeper drilling by Newpark's customers.
     In the three months ended March 31, 1996, the volume of NOW processed
     increased by 8% compared to the same period in 1995.
 
  .  A NOW facility, located near Fannett, Texas, was opened in the third
     quarter of 1995 in anticipation of the conversion of the Big Hill
     facility into a NORM facility, and additional wells were drilled at the
     Big Hill facility, providing a further increase in waste disposal
     capacity.
 
  .  Newpark extended its mat rental services to non-oilfield uses in Florida
     and Georgia.
 
  .  Newpark initiated a joint venture to provide its mat rental services to
     the exploration and production market in Venezuela.
 
  NORM Direct Injection License. On May 21, 1996, Newpark was awarded a new
license from the State of Texas permitting receipt of NORM waste and direct
injection disposal of NORM at its Big Hill facility, without the requirement
to process the waste until it attains NOW characteristics. The Big Hill
facility will become Newpark's principal NORM disposal facility. Under the new
license, the processing facility and the disposal wells will be located at the
same site, minimizing transportation costs. Additionally, since the new
license allows injection of more concentrated NORM into the wells, subject
only to Newpark's facility contamination limits, the volume of material
injected is substantially lower than for the prior process, significantly
expanding the capacity and extending the useful life of the site. Newpark
believes that the new license will allow it to reduce prices to customers and
encourage the use of the direct injection process for the disposal of large
volumes of NORM. The recent contract with a major oil company for a large NORM
disposal project is the first remediation project to take advantage of this
new direct injection license.
 
  Developments related to NOW. Newpark processed and disposed of 745,000
barrels of NOW in the first quarter of 1996, of which 622,000 barrels were
generated from current drilling and production operations and 123,000 barrels
were generated from the remediation of old pits and production facilities,
compared with 690,000 barrels in the first quarter of 1995, of which 600,000
were from current drilling and production operations and 90,000 were from
remediation activities. Newpark processed and disposed of 2,905,000 barrels of
NOW in 1995, of which 2,364,000 barrels were generated from current drilling
and production operations and 541,000 barrels were generated from the
remediation of old pits and production facilities, compared with 2,329,000
barrels in 1994, of which 1,974,000 were from current drilling and production
operations and 355,000 were from remediation activities.
 
  During 1995, Newpark further expanded its NOW injection facility, located at
Big Hill, Texas, drilling two additional injection wells and constructing a
grinding mill at the site to more efficiently handle the large quantities of
waste resulting from the growing remediation market. The mill is used to
reduce and make uniform the size of the particles in the waste stream to
maintain desired flow characteristics in Newpark's injection wells. In
September 1995, Newpark opened its second injection site, at Fannett, Texas,
drilling two wells at that facility, and in the fourth quarter, completed a
bulk barge unloading facility adjacent to the original Port Arthur processing
facility. Together with additions to personnel and equipment at its receiving
facilities, this increased Newpark's NOW processing capacity to approximately
500,000 barrels per month. Newpark intends to use the Big Hill facility
primarily for disposal of NORM, and the Fannett facility will become Newpark's
primary facility for the disposal of NOW.

  Services to wetlands construction projects. Many of the environmental
concerns that have affected drilling in the environmentally sensitive marshes
of the U.S. Gulf Coast are now beginning to affect other construction
activities in the U.S. Gulf Coast and other geographic areas. Federal and
state regulatory agencies have begun to require increased precautions to
prevent construction-related damage to the environment in wetlands areas
throughout the United States. Newpark believes that its prefabricated mat
technology is well-suited for use in construction projects in wetlands and
other areas characterized by unstable soil conditions. During 1995, Newpark
performed projects in connection with pipeline, electrical utility and highway
construction projects in Georgia, Florida, Texas and Louisiana. Newpark
anticipates that similar opportunities will allow it to continue to diversify
its geographic base by participating in construction related activities in
other states.
 
  Venezuela joint venture. The Venezuelan government has recently enacted
legislation designed to speed the opening of its petroleum sector to foreign
investment, including international oil companies, in furtherance of a
national objective of increasing that country's production of oil to 5 million
barrels per day by the year 2005. Many of the international oil companies
investing in Venezuela are Newpark's customers in the United States. During
the first quarter of 1995, Newpark invested in a joint venture, in which
Newpark holds a 38.8% interest, providing mat rental services in Venezuela in
support of oil and gas exploration and production activities. A total of 7,000
mats were shipped to the market during the year and, by year end,
substantially all were under contract to a customer. As of June 30, 1996,
there were approximately 18,000 mats in inventory in Venezuela. Newpark
expects that activity in Venezuela will continue to increase as further
exploration concessions are granted.
   
  Drilling activity. The level of drilling activity in Newpark's service areas
declined 4%, to an average of 194 rigs working in 1995, compared to 202 during
1994. This mirrored the decline in the U.S. rig count, which averaged 723 in
1995 compared to 774 in 1994. The 1995 activity level was the second lowest
since 1940, after an average of 717 recorded in 1992. In much of the coastal
marsh and inland waters, termed the "transition zone", the high cost
associated with access to the site and the lack of seismic data has been an
obstacle to development. As a result, the area has been less actively drilled
compared to offshore and land areas. High quality seismic data has become
available for sites in the transition zone only through recent improvements in
technology. The increased use of advanced seismic data and the computer-
enhanced interpretation of that data has enabled Newpark's customers to select
exploratory drilling sites with greater likelihood of success. This enables
them to undertake more expensive projects, such as drilling in the transition
zone along the U.S. Gulf Coast region.     
 
  Such projects rely heavily on services such as Newpark's integrated
environmental services. Deeper wells require the construction of larger
locations to accommodate the drilling equipment and the equipment for handling
drilling fluids and associated wastes; such locations generally are in service
for significantly longer periods and generate additional mat rental revenues.
Deeper wells also require more chemically complex drilling fluid programs.
Newpark believes that deeper drilling has contributed significantly to the
increased demand for Newpark's services.
 
REGULATORY BACKGROUND
 
  The oilfield market for environmental services has increased as regulations
have increased. Louisiana, Texas and other states have enacted comprehensive
laws and regulations governing the proper handling of NOW and NORM. This also
has heightened the awareness of both the generators of waste and landowners of
the need for proper treatment and disposal of such waste in both the drilling
of new wells and the remediation of production facilities.
 
  For many years, prior to current regulation, industry practice was to allow
NOW to remain in the environment. Onshore, surface pits were used for the
disposal of NOW; offshore, NOW was discharged directly into the water. As a
result of increasing public concern over the environment, NOW disposal has in
recent years
 
                                      30
<PAGE>
 
become subject to public scrutiny and governmental regulation. Operators of
exploration and production facilities, including major and independent oil
companies, have found themselves subject to laws and regulations issued by
numerous jurisdictions and agencies. These laws and regulations have imposed
strict requirements for ongoing drilling and production activities in certain
geographic areas, as well as for the remediation of sites contaminated by past
disposal practices and, in many respects, have prohibited the prior disposal
practices. In addition, operators have become concerned about possible long-
term liability for remediation, and landowners have become more aggressive
about land restoration. For these reasons, operators are increasingly
retaining service companies, such as Newpark, to devise and implement
comprehensive waste management techniques to handle waste on an ongoing basis
and to remediate past contamination of oil and gas properties.
 
  Late in 1992, the Louisiana Department of Environmental Quality ("DEQ")
began to promulgate and enforce new, stricter limits on the level of radium
concentration above which NOW became categorized as NORM. NORM regulations
require more stringent worker protection, handling and storage procedures than
those required of NOW under Louisiana Statewide Executive Order 29-B.
Uncertainty in measuring NORM concentration was created by apparent
inconsistencies in the results produced by alternative testing methodologies
allowed in then current regulations. Early in 1994, DEQ published draft NORM
regulations which, with minor modification, became effective January 20, 1995,
as LAC 33:XV.1401-1420, Chapter 14. In Texas, the Railroad Commission adopted
final rules ("Rule 94") effective February 1, 1995. Adoption of these
regulations has resolved the regulatory uncertainty associated with NORM in
Texas and Louisiana.
 
  The primary laws that have helped to create the market for Newpark's
environmental services in the U.S. Gulf Coast region, and which apply to
Newpark in the conduct of its business, are the Resource Conservation and
Recovery Act of 1976, as amended in 1984 ("RCRA"), the Comprehensive
Environmental Response, Compensation, and Liability Act, as amended in 1986
("CERCLA"), the laws and regulations promulgated by the states of Louisiana,
Texas and Alabama, the Federal Water Pollution Control Act, as amended (the
"Clean Water Act"), and the Federal Oil Pollution Act of 1990 ("OPA"). These
laws are discussed below under "Environmental Regulation".
 
DESCRIPTION OF BUSINESS
 
 Oilfield Waste Disposal
 
  NOW Waste Processing. Generally under state regulation, if NOW cannot be
treated for discharge or disposed of on the oil or gas lease location where it
is generated, it must be transported to a licensed NOW disposal or treatment
facility. There are several alternatives for offsite disposal of NOW available
to generators in the U.S. Gulf Coast, including: (i) land-farming, provided by
Newpark's competitors; (ii) processing and conversion of the NOW into a reuse
product; and (iii) underground injection. See "Injection Wells". Newpark
processes NOW waste at a facility located at Port Arthur, Texas, which was
opened in 1991. Newpark also operates six other receiving and transfer
facilities located along the U.S. Gulf Coast from Venice, Louisiana, to Corpus
Christi, Texas. Waste products are collected at the transfer facilities:
offshore exploration and production sites; land and inland waters exploration
and production sites; and remediation of existing or inactive well sites and
production facilities. These facilities are supported by a fleet of 42 double-
skinned barges certified by the U.S. Coast Guard to transport NOW. Waste
received is transported by barge through the Gulf Intracoastal Waterway to
Newpark's processing facility at Port Arthur, Texas, or trucked to facilities
at Fannett or Big Hill, Texas. Since November 1994, Newpark has disposed of a
majority of the waste received at its processing facility by injection of the
waste into disposal wells at its Big Hill facility and, since the third
quarter of 1995, at its Fannett facility, which is currently Newpark's primary
NOW facility.
 
  Previously a large portion and currently a small portion of the waste is
converted into a commercial product that meets the specifications under
applicable federal and state regulations for reuse as a covering material or
cell liner material and other construction purposes at sanitary landfills.
Under these regulations,
 
                                      31
<PAGE>
 
landfills must cover the solid waste deposited daily with earth or other inert
material. Newpark's product is deposited at either the City of Port Arthur
Municipal Landfill or the City of Beaumont Municipal Landfill for use as cover
or construction material pursuant to contracts with the respective cities.
This reuse is conducted under authorization from the Texas Natural Resources
Conservation Commission and is permitted by the Texas Railroad Commission,
under a permit that was renewed in January 1994, for a three year period.
Newpark also has developed alternative uses for the product as roadbase
material or construction fill material.
 
  NORM Processing and Disposal. Newpark's entry into the onsite remediation
(1993) and disposal (1994) of NORM waste is discussed under "Business-
Development of the Business". Many alternatives are available to the generator
for the treatment and disposal of NORM. These include both chemical and
mechanical methods designed to achieve volume reduction, on-site burial of
encapsulated NORM within old well bores, and soil washing and other techniques
of dissolving and suspending the radium in solution for onsite injection of
NORM liquids. When the application of these techniques are insufficient to
bring the site into compliance with applicable regulations, the NORM must be
transported to a licensed storage or disposal facility. The growth in the NORM
disposal market also can be attributed to increased litigation on the part of
landowners who contend that their property has been damaged by past practices
of the oil and gas industry. In some cases, settlement of the litigation has
mandated the remediation of sites by offsite disposal of the NORM waste. In
addition, these lawsuits have caused other operators to dispose of NORM waste
offsite to avoid the threat of future litigation.
 
  Newpark's initial NORM processing facility in Port Arthur, Texas was
licensed in September 1994 and began operations October 21, 1994. During 1995,
Newpark received 70,000 barrels of NORM contaminated waste at its Port Arthur
facility, generally by barge or truck, in drums or other containers, which was
then processed and transported by truck to Newpark's injection well facility.
On May 21, 1996, Newpark was awarded a new license permitting receipt of NORM
waste and direct injection disposal of NORM at its Big Hill, Texas facility,
without the requirement to process the waste until it attains NOW
characteristics, as was the case at the Port Arthur facility. Additionally,
since the processing facility and the disposal wells can now be located at the
same site, transportation costs are minimized. Although Newpark will continue
some processing of NORM as well as NOW at the Port Arthur facility, a
substantial portion of the processing equipment will be moved from Port Arthur
to the Big Hill facility. The new license also allows injection of more
concentrated NORM into the wells, subject only to Newpark's facility
contamination limits, without the introduction of viscosifiers and carrying
agents that often results in significant volume expansion. As a result, the
capacity and useful life of the site is extended. Newpark believes that the
new license will allow it to reduce prices to customers and encourage the use
of the direct injection process for the disposal of large volumes of NORM.
 
  Injection Wells. In February 1993, upon receipt of a permit from the Texas
Railroad Commission, Newpark began development of a 50 acre injection well
facility in the Big Hill Field in Jefferson County, Texas. Newpark's injection
technology is distinguished from conventional methods in that it utilizes
environmentally secure geologic formations which are highly fractured,
allowing Newpark to utilize very low pressure, typically under 100 pounds per
square inch, to move the waste into the injection zone. Conventional wells
typically use pressures as high as 2,000 pounds per square inch. In the event
of a formation failure or blockage of the face of the injection zone, such
pressure can force waste material beyond the intended zone, posing a hazard to
the environment. The low pressure used by Newpark is inadequate to drive the
injected waste from its intended geologic injection zone.
 
  Three wells were initially installed at the Big Hill facility and two
additional wells were successfully completed during 1995. Disposal operations
began at this site in November 1993. During 1995, Newpark licensed and
constructed a new injection well facility at a 400 acre site near Fannett,
Texas, which was placed in service in September 1995. Because of differences
between the geology and physical size of the two sites, the Fannett site is
expected to provide greater capacity than the Big Hill site. The injection
wells at Fannett receive NOW waste from Newpark's processing facilities at
Port Arthur, as well as from customers in the surrounding area.

  Newpark anticipates that it will open additional injection facilities for
both NOW and NORM waste in Louisiana and Texas over the next two to three
years. Newpark has identified a number of sites in the U.S. Gulf Coast region
as suitable for development of such disposal facilities, has received permits
for one additional site in Texas and plans to file for additional permit
authority in Louisiana. Newpark believes that its proprietary injection
technology has application to other markets and waste streams and has begun
preliminary work and analysis to enter the nonhazardous industrial waste
market in the future.
 
  Newpark also operates an analytical laboratory in Lafayette, Louisiana,
which supports all phases of its environmental services and provides
independent laboratory services to the oil and gas industry. These services
include analytical laboratory and sampling services, permit application and
maintenance services and environmental site assessment and audit services.
 
 Mat Rental
 
  In 1988, Newpark acquired the right to use, in Louisiana and Texas, a
patented prefabricated interlocking mat system for the construction of
drilling and work sites, which has displaced use of individual hardwood
boards. This system is quicker to install and remove, substantially reducing
labor costs. It is also stronger, easier to repair and maintain and generates
less waste material during construction and removal than conventional board
roads. In 1994, Newpark acquired the exclusive right to use this system in the
continental U.S. for the life of the patent, which expires in 2003.
 
  Oilfield Use. Newpark provides this patented interlocking mat system to the
oil and gas industry to ensure all-weather access to exploration and
production sites in the unstable soil conditions common along the onshore Gulf
of Mexico. The mats are generally rented to the customer for an initial period
of 60 days; after that time, additional rentals are earned on a monthly basis
until the mats are released by the customer.
 
  Wetlands Use. Beginning in 1994, Newpark recognized the development of a
related use for its patented mat system in providing access roads and
temporary work sites to the pipeline, electrical utility and highway
construction industries. Demand for these services was spurred by Federal
Energy Regulatory Commission orders requiring compliance with environmental
protection rules under the Clean Water Act in the pipeline construction
business. In 1994, Newpark received approximately $2.4 million in revenue from
this source. During 1995, approximately $7 million in revenues was
attributable to wetlands applications.
 
  Rerentals. Drilling and work sites are typically rented by the customer for
an initial period of 60 days. Often, the customer extends the rental term for
additional 30 day periods, resulting in additional revenues to Newpark. These
rerental revenues provide high margins because only minimal incremental
depreciation and maintenance costs accrue to each rerental period. Factors
which may increase rerental revenue include: (i) the trend toward increased
activity in the "transition zone" along the Gulf of Mexico, an area in which
Newpark's mat system provides the primary means of access; (ii) a trend toward
deeper drilling, taking a longer time to reach the desired depth; and, (iii)
the increased frequency of commercial success, requiring logging, testing and
completion (hook-up), extending the period during which access to the site is
required. In the opinion of industry analysts, application of advanced
technologies, particularly the use of three-dimensional seismic data, has
contributed to these trends.
 
  New Products. All of the established mat patents utilize hardwood to
construct the mat. Beginning in 1994, Newpark began funding the development of
a patented synthetic molded mat fabricated from recycled post-consumer
plastic, rubber, fiberglass and resins. A limited number of pre-production
samples of a prototype mat were delivered to Newpark for testing in April
1996. Pending successful results in the testing program and construction by
the manufacturer of a production facility, Newpark expects to begin taking
delivery of commercial quantities of these new mats during 1998. No assurances
can be given, however, that these mats will be successfully produced or become
accepted in the mat rental market.

 Onsite Environmental Management
 
  Promulgation and enforcement of increasingly stringent environmental
regulations affecting drilling and production sites has increased the scope of
services required by the oil companies. Often it is more efficient for the
site operator to contract with a single company that can provide all-weather
site access and provide the required onsite and offsite environmental services
on a fully integrated basis. Newpark provides a comprehensive range of
environmental services necessary for its customers' oil and gas exploration
and production activities.
 
  Site Assessment. Site assessment work begins prior to installation of mats
on a drilling site, and generally begins with a study of the proposed well
site, which includes site photography, background soil sampling, laboratory
analysis and investigation of flood hazards and other native conditions. The
assessment determines whether the site has previously been contaminated and
provides a baseline for later restoration to pre-drilling condition.
 
  Pit Design, Construction and Drilling Waste Management. Under its
Environmentally Managed Pit ("EMP") Program, Newpark constructs waste pits at
drilling sites and monitors the waste stream produced in drilling operations
and the contents and condition of the pits with the objective of minimizing
the amount of waste generated on the site. Where possible, Newpark disposes of
waste onsite by land-farming, through chemical and mechanical treatment of
liquid waste and by annular injection into a suitably permitted underground
formation. Waste water treated onsite may be reused in the drilling process
or, where permitted, discharged into adjacent surface waters.
 
  Regulatory Compliance. Throughout the drilling process, Newpark assists the
operator in interfacing with the landowner and regulatory authorities. Newpark
also assists the operator in obtaining necessary permits and in complying with
record maintenance and reporting requirements.
 
 Site Remediation.
 
  NOW (Drilling). At the completion of the drilling process, under applicable
regulations, waste water on the site may be chemically or mechanically treated
and discharged into surface waters. Other waste that may not remain on the
surface of the site may be land-farmed on the site or injected under permit
into geologic formations to minimize the need for offsite disposal. Any waste
that does not remain onsite must be transported to an authorized facility for
processing and disposal at the direction of the generator or customer.
 
  NOW (Production). Newpark also provides services to remediate production
pits and inactive waste pits including those from past oil and gas drilling
and production operations. Newpark provides the following remediation
services: (i) analysis of the contaminants present in the pit and a
determination of whether remediation is required by applicable state
regulation; (ii) treatment of waste onsite, and where permitted,
reintroduction of that material into the environment; and (iii) removal,
containerization and transportation to Newpark's processing facility of NOW
waste not treated onsite.
 
  NORM. In January 1994, Newpark became a licensed NORM contractor, allowing
Newpark to perform site remediation work at NORM contaminated facilities in
Louisiana and Texas. Because of the need for increased worker-protective
equipment, extensive decontamination procedures and other regulatory
compliance issues at NORM facilities, the cost of providing such services is
materially greater than at NOW facilities and such services generate
proportionately higher revenues and operating margins than similar services at
NOW facilities.
 
  Site Closure. The location is restored to its pre-drilling condition and
reseeded with native grasses. Closure also involves delivery of test results
indicating that closure has been completed in compliance with applicable
regulations. This information is important to the customer because the
operator is subject to future regulatory review and audits. In addition, the
information may be required on a current basis if the operator is subject to a
pending regulatory compliance order.

 Wood Product Sales
 
  By the end of 1991, Newpark had become aware of increasing environmental
regulation affecting wetlands areas. These regulations have affected the oil
and gas drilling industry as well as pipeline, electrical distribution and
highway projects. In anticipation of increased demand for hardwood lumber used
in providing access to such wetlands sites, Newpark purchased a sawmill in
Batson, Texas, in October 1992. The mill's products include lumber, timber,
and wood chips, as well as bark and sawdust. Pulp and paper companies in the
area supply a large proportion of the hardwood logs processed at the sawmill
and, in turn, are the primary customers for wood chips created in the milling
process. During 1993, Newpark invested approximately $1 million in expansion
of the sawmill to increase its capacity for producing wood chips. During 1995,
Newpark invested an additional $750,000 to install a log watering system to
maintain the level of moisture in the wood chips produced, as desired by its
customers, and for expanded and improved sawing capacity, which improved both
production and efficiency. Newpark believes that the capacity of the sawmill
will be sufficient to meet its anticipated hardwood lumber needs for the
foreseeable future.
 
 General Oilfield Services
 
  Newpark performs general oilfield services throughout the U.S. Gulf Coast
area between Corpus Christi, Texas and Pensacola, Florida. General oilfield
services performed by Newpark include preparing work sites for the
installation of mats, connecting wells and placing them in production, laying
flow lines and infield pipelines, building permanent roads, grading, lease
maintenance (the maintenance and repair of producing well sites), cleanup and
general roustabout services. General oilfield services are typically performed
under short-term time and material contracts, which are obtained by direct
negotiation or bid.
 
INTERNATIONAL EXPANSION
 
  During the first quarter of 1995, Newpark initiated participation in a
venture which provides mat rental services to the oil and gas industry in
Venezuela. Revenue from foreign operations has been immaterial in each of the
past three years. Newpark is currently in discussions with its joint venture
partners in Venezuela for the purchase of their interests in such venture, and
Newpark may acquire such interests during 1996. Newpark also is currently
reviewing expansion opportunities for its mat rental services in other foreign
markets, including Europe, Africa, Asia and South America.
 
SOURCES AND AVAILABILITY OF RAW MATERIALS AND EQUIPMENT
 
  Newpark believes that its sources of supply for any materials or equipment
used in its businesses are adequate for its needs and that it is not dependent
upon any one supplier. No serious shortages or delays have been encountered in
obtaining any raw materials.
 
PATENTS AND LICENSES
 
  Newpark seeks patents and licenses on new developments whenever feasible and
has recently applied for U.S. patents on its new NOW and NORM waste processing
and injection disposal system. Newpark has the exclusive license for the life
of the patent (which expires in 2003) to use, sell and lease the prefabricated
mats that it uses in connection with its site preparation business in the 48
contiguous states of the United States. The licensor has the right to sell
mats in states where Newpark is not engaged in business, but only after giving
Newpark the opportunity to take advantage of the opportunity itself. The
license is subject to a royalty which Newpark can satisfy by purchasing
specified quantities of mats annually from the licensor.
 
  Newpark relies on a variety of unpatented proprietary technologies and know-
how in the processing of NOW and NORM. Although Newpark believes that this
technology and know-how are important factors in the environmental services
business, competitive products and services have been successfully developed
and marketed by others. Newpark believes that its reputation in its industry,
the range of services
 
                                      35
<PAGE>
 
offered, ongoing technical development and know-how, responsiveness to
customers and understanding of regulatory requirements are of equal or greater
competitive significance than its existing proprietary rights.
 
DEPENDENCE UPON LIMITED NUMBER OF CUSTOMERS
 
  Newpark's customers are principally major and independent oil and gas
exploration and production companies operating in the U.S. Gulf Coast area,
with the vast majority of Newpark's customers concentrated in Louisiana and
Texas.
 
  During the year ended December 31, 1995, approximately 30% of Newpark's
revenues were derived from 14 major oil companies, and one other customer
accounted for approximately 16% of consolidated revenues. Given current market
conditions and the nature of the products involved, Newpark does not believe
that the loss of this customer would have a material adverse effect upon
Newpark.
 
  Newpark performs services either pursuant to standard contracts or under
longer term negotiated agreements. As most of Newpark's agreements with its
customers are cancelable upon limited notice, Newpark's backlog is not
significant. For the year ended December 31, 1995, approximately half of the
revenues of the environmental services segment were obtained on a bid basis,
and half of its revenues were derived on a negotiated or contractual basis.
 
  Newpark does not derive a significant portion of its revenues from
government contracts of any kind.
 
COMPETITION
 
  Newpark operates in highly competitive industry segments. Newpark believes
that the principal competitive factors in its businesses are price,
reputation, technical proficiency, reliability, quality and breadth of
services offered, managerial experience. Newpark believes that it effectively
competes on the basis of these factors and that its competitive position
benefits from its proprietary position with respect to the patented mat system
used in its site preparation business, its proprietary treatment and disposal
methods for both NOW and NORM waste streams and its ability to provide its
customers with an integrated well site management program including
environmental and general oilfield services.
 
  It is often more efficient for the site operator to contract with a single
company that can prepare the well site and provide the required onsite and
offsite environmental services. Newpark believes that its ability to provide a
number of services as part of a comprehensive program enables Newpark to price
its services competitively.
 
  The NOW disposal market is very large. Only a small portion of the total
waste generated is taken to a commercial disposal facility and many other
methods exist for dealing with the waste stream. In the areas served by
Newpark, there are at least 250 permitted commercial facilities, including
landfarms, landfills and injection facilities authorized to dispose of NOW.
There also are thousands of infield injection wells owned and operated by oil
and gas producers.
 
ENVIRONMENTAL DISCLOSURES
 
  Newpark has sought to comply with all applicable regulatory requirements
concerning environmental quality. Newpark has made, and expects to continue to
make, the capital expenditures necessary to maintain environmental compliance
at its facilities, but, under current laws and regulations, does not expect
that these will become material in the foreseeable future. No material capital
expenditures for environmental compliance were made during 1995.
 
  Newpark derives a significant portion of its revenue from providing
environmental services to its customers. These services have become necessary
in order for these customers to comply with regulations governing the
discharge of materials into the environment. Substantially all of Newpark's
capital expenditures made during 1994 and 1995, and those planned for 1996,
are directly or indirectly the result of such regulation.
 
                                      36

EMPLOYEES
 
  At June 30, 1996, Newpark employed approximately 529 full and part-time
personnel, none of which are represented by unions. Newpark considers its
relations with its employees to be satisfactory.
 
ENVIRONMENTAL REGULATION
 
  Newpark's business is affected both directly and indirectly by governmental
regulations relating to the oil and gas industry in general, as well as
environmental, health and safety regulations that have specific application to
Newpark's business. Newpark, through the routine course of providing its
services, handles and profiles hazardous regulated material for its customers.
Newpark also handles, processes and disposes of nonhazardous regulated
materials. This section discusses various federal and state pollution control
and health and safety programs that are administered and enforced by
regulatory agencies, including, without limitation, the U.S. Environmental
Protection Agency ("EPA"), the U.S. Coast Guard, the U.S. Army Corps of
Engineers, the Texas Natural Resource Conservation Commission, the Texas
Department of Health, the Texas Railroad Commission, the Louisiana Department
of Environmental Quality and the Louisiana Department of Natural Resources.
These programs are applicable or potentially applicable to Newpark's current
operations. Although Newpark intends to make capital expenditures to expand
its environmental services capabilities, Newpark believes that it is not
presently required to make material capital expenditures to remain in
compliance with federal, state and local laws and regulations relating to the
protection of the environment.
 
  RCRA. The Resource Conservation and Recovery Act of 1976, as amended in
1984, ("RCRA"), is the principal federal statute governing hazardous waste
generation, treatment, storage and disposal. RCRA and EPA-approved state
hazardous waste management programs govern the handling of "hazardous wastes".
Under RCRA, liability and stringent operating requirements are imposed on a
person who is either a "generator" or "transporter" of hazardous waste or an
"owner" or "operator" of a hazardous waste treatment, storage or disposal
facility. The EPA and the states have issued regulations pursuant to RCRA for
hazardous waste generators, transporters and owners and operators of hazardous
waste treatment, storage or disposal facilities. These regulations impose
detailed operating, inspection, training and emergency preparedness and
response standards and requirements for closure, continuing financial
responsibility, manifesting of waste, record-keeping and reporting, as well as
treatment standards for any hazardous waste intended for land disposal.
 
  Newpark's primary operations involve NOW, which is exempt from
classification as a RCRA-regulated hazardous waste. However, extensive state
regulatory programs govern the management of such waste. In addition, in
performing other services for its customers, Newpark is subject to both
federal (RCRA) and state solid or hazardous waste management regulations as
contractor to the generator of such waste.
 
  At various times in the past, proposals have been made to rescind the
exemption that excludes NOW from regulation as hazardous waste under RCRA.
Repeal or modification of this exemption by administrative, legislative or
judicial process could require Newpark to change significantly its method of
doing business. There is no assurance that Newpark would have the capital
resources available to do so, or that it would be able to adapt its
operations.
 
  Newpark's operations also require it to comply with Subtitle I of RCRA,
which regulates underground storage tanks in which liquid petroleum or
hazardous substances are stored. States have similar regulations, many of
which are more stringent in some respects than federal programs. The
implementing regulations require that each owner or operator of an underground
tank notify a designated state agency of the existence of such underground
tank, specifying the age, size, type, location and use of each such tank. The
regulations also impose design, construction and installation requirements for
new tanks, tank testing and inspection requirements, leak detection,
prevention, reporting and cleanup requirements, as well as tank closure and
removal requirements.
 
  Newpark has a number of underground storage tanks that are subject to the
requirements of RCRA and applicable state programs. Violators of any of the
federal or state regulations may be subject to enforcement orders or
significant penalties by the EPA or the applicable state agency. Newpark is
not aware of any instances
 
                                      37
<PAGE>
 
in which it has incurred liability under RCRA for failure to comply with
regulations applicable to its underground storage tanks. However, cleanup
costs associated with releases from these underground storage tanks or costs
associated with changes in environmental laws or regulations could be
substantial and could have a material adverse effect on Newpark.
 
  CERCLA. The Comprehensive Environmental Response, Compensation and Liability
Act, as amended in 1986, ("CERCLA"), provides for immediate response and
removal actions coordinated by the EPA for releases of hazardous substances
into the environment and authorizes the government, or private parties, to
respond to the release or threatened release of hazardous substances. The
government may also order persons responsible for the release to perform any
necessary cleanup. Liability extends to the present owners and operators of
waste disposal facilities from which a release occurs, persons who owned or
operated such facilities at the time the hazardous substances were released,
persons who arranged for disposal or treatment of hazardous substances and
waste transporters who selected such facilities for treatment or disposal of
hazardous substances. CERCLA has been interpreted to create strict, joint and
several liability for the costs of removal and remediation, other necessary
response costs and damages for injury to natural resources.
 
  Among other things, CERCLA requires the EPA to establish a National
Priorities List ("NPL") of sites at which hazardous substances have been or
are threatened to be released and that require investigation or cleanup. The
NPL is constantly expanding. In addition, the states in which Newpark conducts
operations have enacted similar laws and keep similar lists of sites which may
be in need of remediation.
 
  Although Newpark primarily handles oilfield waste classified as NOW under
relevant laws, this waste typically contains constituents designated by the
EPA as hazardous substances under RCRA, despite the current exemption of NOW
from hazardous substance classification, or under another environmental
statute referenced by CERCLA. Where Newpark's operations result in the release
of hazardous substances, including releases at sites owned by other entities
where Newpark performs its services, Newpark could incur CERCLA liability.
Previously owned businesses also may have disposed or arranged for disposal of
hazardous substances that could result in the imposition of CERCLA liability
on Newpark in the future. In particular, divisions and subsidiaries previously
owned by Newpark were involved in extensive mining operations at facilities in
Utah and Nevada. In addition, divisions and subsidiaries previously owned by
Newpark were involved in waste generation and management activities in
numerous states. These activities involved substances that may be classified
as CERCLA hazardous substances. Any of those sites or activities potentially
could be the subject of future CERCLA damage claims.
 
  Newpark currently is, and in the past has been, named by the EPA as a
potentially responsible party in CERCLA actions based on its disposal of
oilfield wastes at such sites, but the liability associated with such actions
has not been material. Nonetheless, the identification of additional sites at
which clean-up action is required could subject Newpark to liabilities which
could have a material adverse effect on Newpark.
 
  The Clean Water Act. The Clean Water Act regulates the discharge of
pollutants, including NOW, into waters. The Clean Water Act establishes a
system of standards, permits and enforcement procedures for the discharge of
pollutants from industrial and municipal waste water sources. The law sets
treatment standards for industries and waste water treatment plants and
provides federal grants to assist municipalities in complying with the new
standards. In addition to requiring permits for industrial and municipal
discharges directly into waters of the United States, the Clean Water Act also
requires pretreatment of industrial waste water before discharge into
municipal systems. The Clean Water Act gives the EPA the authority to set
pretreatment limits for direct and indirect industrial discharges.
 
  In addition, the Clean Water Act prohibits certain discharges of oil or
hazardous substances and authorizes the federal government to remove or
arrange for removal of such oil or hazardous substances. The Clean Water Act
also requires the adoption of the National Contingency Plan to cover removal
of such materials. Under the Clean Water Act, the owner or operator of a
vessel or facility may be liable for penalties and costs incurred by the
federal government in responding to a discharge of oil or hazardous
substances.
 
  Newpark treats and discharges waste waters at certain of its facilities.
These activities are subject to the requirements of the Clean Water Act and
federal and state enforcement of these regulations.
 
                                      38
<PAGE>
 
  The Clean Water Act also has a significant impact on the operations of
Newpark's customers. The EPA Region 6 Outer Continental Shelf ("OCS") permit
covering oil and gas operations in federal waters in the Gulf (seaward of the
Louisiana and Texas territorial seas) was reissued in November, 1992 and
modified in December, 1993. This permit includes stricter discharge limits for
oil and grease concentrations in produced waters to be discharged. These
limits are based on the Best Available Treatment ("BAT") requirements
contained in the Oil and Gas Offshore Subcategory national guidelines which
were published March 3, 1993. Additional requirements include toxicity testing
and bioaccumulation monitoring studies of proposed discharges.
 
  EPA Region 6, which includes Newpark's market, continues to issue new and
amended National Pollution Discharge Elimination System ("NPDES") general
permits further limiting or restricting substantially all discharges of
produced water from the Oil and Gas Extraction Point Source Category into
waters of the United States. These permits include:
 
  .  Onshore subcategory permits for Texas, Louisiana, Oklahoma and New
     Mexico issued in February, 1991 (56 Fed. Reg. 7698). These permits
     completely prohibit the discharge of drilling fluids, drill cuttings,
     produced water or sand, and various other oilfield wastes generated by
     onshore operations into waters of the U.S. This provision has the effect
     of requiring that most oilfield wastes follow established state disposal
     programs.
 
  .  Permits for produced water and produced sand discharges into coastal
     waters of Louisiana and Texas issued on January 9, 1995 (60 Fed. Reg.
     2387). Coastal means "any water landward of the territorial seas... or
     any wetlands adjacent to such waters". All such discharges must cease by
     January 1, 1997.
 
  .  The Outer Continental Shelf (OCS) permit for the western Gulf of Mexico,
     covering oil and gas operations in federal waters (seaward of the
     Louisiana and Texas territorial seas) reissued in November 1992 and
     modified in December 1993. It is expected to be combined with an OCS
     general permit covering new sources at its next revision.
     
  .  Permits for the territorial seas of Louisiana and Texas which were
     scheduled to be proposed in the spring of 1995. Although the permits
     have not yet been proposed, the EPA indicates that they are still under
     active consideration by the EPA and should be proposed in the future.
     The territorial seas part of" the Offshore Subcategory begins at the
     line of ordinary low water along the part of the coast which is in
     direct contact with the open sea, and extends out three nautical miles.
     These permits will cover both existing sources and new sources. All
     discharges in Louisiana state waters must comply with any more stringent
     requirements contained in Louisiana Water Quality Regulations, LAC
     33.IX.7.708.     
 
  The combined effect of all these regulations will closely approach a "zero
discharge standard" affecting all waters except those of the OCS. Newpark and
many industry participants believe that these permits may ultimately lead to a
total prohibition of overboard discharge in the Gulf of Mexico.
 
  The Clean Air Act. The Clean Air Act provides for federal, state and local
regulation of emissions of air pollutants into the atmosphere. Any
modification or construction of a facility with regulated air emissions must
be a permitted or authorized activity. The Clean Air Act provides for
administrative and judicial enforcement against owners and operators of
regulated facilities, including substantial penalties. In 1990, the Clean Air
Act was reauthorized and amended, substantially increasing the scope and
stringency of the Clean Air Act's regulations. The Clean Air Act has very
little impact on Newpark's operations.
   
  Oil Pollution Act of 1990. The Oil Pollution Act of 1990 ("OPA") contains
liability provisions for cleanup costs, natural resource damages and property
damages resulting from discharges of oil into navigable waters, as well as
substantial penalty provisions. The OPA also requires double hulls on all new
oil tankers and barges operating in waters subject to the jurisdiction of the
United States. All marine vessels operated by Newpark already meet this
requirement.     
 
  State Regulation. In 1986, the Louisiana Department of Natural Resources
promulgated Order 29-B. Order 29-B contains extensive rules governing pit
closure and the generation, treatment, storage, transportation and disposal of
NOW. Under Order 29-B, onsite disposal of NOW is limited and is subject to
stringent guidelines. If these guidelines cannot be met, NOW must be
transported and disposed of offsite in accordance with the
 
                                      39
<PAGE>
 
provisions of Order 29-B. Moreover, under Order 29-B, most, if not all, active
waste pits must be closed or modified to meet regulatory standards; those pits
that continue to be allowed may be used only for a limited time. A material
number of these pits may contain sufficient concentrations of NORM to become
subject to regulation by the DEQ. Rule 8 of the Texas Railroad Commission also
contains detailed requirements for the management and disposal of NOW and Rule
94 governs the management and disposal of NORM. In addition, the Texas
Legislature recently enacted a law that has established an Oilfield Cleanup
Fund to be administered by the Texas Railroad Commission to plug abandoned
wells if the Commission deems it necessary to prevent pollution, and to
control or clean up certain oil and gas wastes that cause or are likely to
cause pollution of surface or subsurface water.
 
  The Railroad Commission of Texas Rule 91 (16 TAC 3.91) became effective
November 1, 1993. This rule regulates the cleanup of spills of crude oil and
gas exploration and production activities including transportation by
pipeline. In general, contaminated soils must be remediated to oil and grease
content of less than 1%.
 
  Many states maintain licensing and permitting procedures for the
construction and operation of facilities that emit pollutants into the air. In
Texas, the Texas Natural Resource Conservation Commission (the "TNRCC")
requires companies that emit pollutants into the air to apply for an air
permit or to satisfy the conditions for an exemption. Newpark has obtained
certain air permits and believes that it is exempt from obtaining other air
permits at its facilities including its Port Arthur, Texas, NOW processing
facility. Newpark met with the TNRCC and filed for an exemption in the fall of
1991. A subsequent renewal letter was filed in 1995. Based upon its feedback
from the TNRCC, Newpark expects that it will continue to remain exempt.
However, should it not remain exempt, Newpark believes that any remedial
actions that the TNRCC may require with regard to non-exempt air emissions
would not have a material adverse effect on the consolidated financial
statements of Newpark.
 
  Other Environmental Laws. Newpark is subject to the Occupation Safety and
Health Act that imposes requirements for employee safety and health and
applicable state provisions adopting worker health and safety requirements.
Moreover, it is possible that other developments, such as increasingly
stricter environmental, safety and health laws, and regulations and
enforcement policies thereunder, could result in substantial additional
regulation of Newpark and could subject to further scrutiny Newpark's
handling, manufacture, use or disposal of substances or pollutants. Newpark
cannot predict the extent to which its operations may be affected by future
enforcement policies as applied to existing laws or by the enactment of new
statutes and regulations.
 
PROPERTIES
 
  With few exceptions, Newpark leases its principal facilities and certain
equipment.
 
  Newpark's corporate offices in Metairie, Louisiana, are occupied at an
annual rental of approximately $127,000 under a lease expiring in December
1997.
 
  Its NOW processing facility in Port Arthur, Texas, is occupied at a current
annual rental of $168,000 under a lease which, as a result of Newpark's 1995
exercise of the first of three four-year renewal options, now expires in 1999.
The facility, which is located on 2.9 acres near the Intracoastal Waterway,
was constructed by the landowner to Newpark's specifications beginning late in
1990 and began operations in mid 1991.
   
  Newpark's NORM processing facility is also located in Port Arthur, Texas on
three acres of leased land adjacent to the NOW facility. Annual property
rentals are currently $37,000. The lease expires in July 1997 and has two
five-year renewal options available. Newpark constructed the processing
facility during 1994.     
   
  Newpark owns two injection disposal sites in Jefferson County, Texas, one on
47 acres of land and the other on 394 acres, of which 284 acres are owned by
Newpark and 110 acres are currently leased by Newpark. Newpark is in the
processing of exercising its option to purchase the 110 acres it is currently
leasing at this site. Seven wells are currently operational at these sites.

  Newpark maintains a fleet of 46 barges of which 21 are owned by Newpark, 15
are on daily rental agreements, six are under 10-year lease terms and four are
under seven-year lease terms. Forty-two of the barges are used to transport
waste to processing stations and are certified for this purpose by the U. S.
Coast Guard. Annual rentals under the barge leases totaled approximately
$1,500,000 during 1995.     
 
  Additional facilities are held under short-term leases with annual rentals
aggregating approximately $800,000 during 1995. Newpark believes that its
facilities are suitable for their respective uses and adequate for current
needs.
 
  Newpark owns property leased to others and used as a marine repair facility
occupying approximately 23 acres on an island in the Houston Ship Channel. In
December 1993, the property was leased to a third party that also obtained the
option to purchase the facility as part of the lease agreement. Early in 1994,
Newpark entered into a new financing of the property.
 
  Newpark also owns 80 acres occupied as a sawmill facility near Batson,
Texas. Newpark believes this facility is adequate for current production
needs.
 
LEGAL PROCEEDINGS
 
  Newpark and its subsidiaries are involved in litigation and other claims or
assessments on matters arising in the normal course of business. In the
opinion of Newpark, any recovery or liability in these matters should not have
a material effect on Newpark's consolidated financial statements.

                         DESCRIPTION OF CAPITAL STOCK
 
  Newpark's authorized capital stock consists of (i) 20,000,000 shares of
Common Stock, $.01 par value per share; and (ii) 1,000,000 shares of Preferred
Stock, $.01 par value per share. All outstanding shares of Common Stock are
fully paid and nonassessable.
 
  The following summaries of certain provisions of the capital stock of
Newpark do not purport to be complete and are subject to, and qualified in
their entirety by, the provisions of Newpark's Certificate of Incorporation
and Bylaws.
 
COMMON STOCK
   
  As of July 31, 1996, there were 10,981,244 outstanding shares of Common
Stock held by 4,105 holders of record. Each share of Common Stock has an equal
and ratable right to receive dividends when, as and if declared by the Board
of Directors out of assets legally available therefor and subject to the
dividend obligations of Newpark to the holders of any preferred stock then
outstanding. See "Dividend Policy".     
 
  In the event of a liquidation, dissolution or winding up of Newpark, the
holders of Common Stock are entitled to share equally and ratably in the
assets available for distribution after the payment of all liabilities and
subject to any prior rights of any holders of preferred stock that at the time
may be outstanding.
 
  The holders of Common Stock have no pre-emptive rights, conversion rights,
redemption provisions or sinking fund provisions. Each share of Common Stock
is entitled to one vote in the election of directors and on all matters
submitted to a vote of stockholders. Stockholders are not entitled to cumulate
votes in the election of directors and, therefore, holders of a majority of
the outstanding shares of Common Stock can elect all the directors.
 
  The Common Stock offered hereby, when issued and sold as contemplated by
this Prospectus, will be validly issued, fully paid and nonassessable.
 
PREFERRED STOCK
 
  Preferred stock may be issued from time to time in one or more series, and
the Board of Directors, without further approval of the stockholders, is
authorized to fix the dividend rates and terms, conversion rights, voting
rights, redemption rights and terms (including sinking fund provisions),
liquidation preferences and any other rights, preferences, privileges and
restrictions applicable to each series of preferred stock. The purpose of
authorizing the Board of Directors to determine such rights and preferences is
to eliminate delays associated with a stockholder vote on specific issuances.
The issuance of preferred stock, while providing flexibility in connection
with possible acquisitions and other corporate purposes, could, among other
things, adversely affect the voting power of the holders of Common Stock and,
under certain circumstances, make it more difficult for a third party to gain
control of Newpark.
 
CERTAIN CHARTER PROVISIONS
 
  Newpark's Certificate of Incorporation provides that Newpark shall indemnify
its officers and directors to the fullest extent permitted by Delaware law
against claims arising out of their actions as officers or directors of
Newpark. The Certificate of Incorporation also provides that, to the fullest
extent permitted by law, Newpark's directors shall not be personally liable
for monetary damages for breach of the director's fiduciary duty of care to
Newpark or its stockholders. This provision does not eliminate the director's
duty of care or eliminate a stockholder's right to seek equitable remedies
such as an injunction or other forms of non-monetary relief. Each director
will continue to be subject to liability for (i) breach of the director's duty
of loyalty to Newpark or its stockholders; (ii) acts or omissions not in good
faith or which involve intentional misconduct or knowing violation of law;
(iii) improper declarations of dividends; and (iv) transactions from which the
director derived
 
                                      44
<PAGE>
 
an improper personal benefit. The provision also does not affect a director's
responsibilities under any other law, such as the Federal securities laws or
Federal or state environmental laws.
 
  Newpark also is authorized by its Certificate of Incorporation to purchase
and maintain insurance for its officers and directors against claims arising
out of their actions as officers or directors of Newpark, whether or not
Newpark would have the power to indemnify such officers or directors for the
claim under applicable law. Newpark currently does not maintain such
insurance.
 
  Pursuant to the Certificate of Incorporation, Newpark has elected not to be
governed by Section 203 of the Delaware General Corporation Law. Section 203
generally prevents a corporation from entering into certain business
combinations with an interested stockholder (defined as any person or entity
that is the beneficial owner of at least 15% of a corporation's voting stock)
or its affiliates, unless (i) the transaction is approved by the board of
directors of the corporation prior to such business combination; or (ii) the
interested stockholder acquires 85% or the corporation's voting stock in the
same transaction in which the stockholder exceeds 15%; or (iii) the business
combination is approved by the board of directors and by a vote of two-thirds
of the outstanding voting stock not owned by the interested stockholder.
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar for the Common Stock is American Stock
Transfer & Trust Company of New York.

  The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that the Underwriters will be
obligated to purchase all of the Shares offered hereby (other than those
shares covered by the over-allotment option described below) if any are
purchased. The Underwriting Agreement provides that in the event of a default
by an Underwriter, in certain circumstances the purchase commitments of non-
defaulting Underwriters may be increased or the Underwriting Agreement may be
terminated.
 
  Newpark has granted to the Underwriters an option, expiring at the close of
business on the 30th day after the date of this Prospectus, to purchase up to
450,000 additional shares from Newpark at the initial public offering price,
less the underwriting discounts and commissions, all as set forth on the cover
page of this Prospectus. Such option may be exercised only to cover over-
allotments in the sale of the shares of Common Stock offered hereby. To the
extent that this option to purchase is exercised, each Underwriter will become
obligated, subject to certain conditions, to purchase approximately the same
percentage of such additional shares of Common Stock as it was obligated to
purchase pursuant to the Underwriting Agreement.
 
  Newpark has been advised by the Representatives that the Underwriters
propose to offer the Shares to the public initially at the public offering
price set forth on the cover page of this Prospectus and, through the
Representatives, to certain dealers at such price less a concession of $
per share, and the Underwriters and such dealers may allow a discount of
$        per share on sales to certain other dealers. After the initial public
offering, the public offering price and concession and discount to dealers may
be changed by the Representatives.
 
  Newpark has agreed that it will not offer, sell, announce its intention to
sell, pledge or otherwise dispose of, directly or indirectly, or file with the
Securities and Exchange Commission a registration statement under the
Securities Act relating to, any additional shares of its Common Stock or
securities convertible into or exchangeable for any shares of its Common Stock
without the prior written consent of CS First Boston Corporation for a period
of 90 days after the date of this Prospectus, except issuances of shares
pursuant to employee benefit plans (including stock option plans) existing on
the date hereof. In addition, directors and executive officers of Newpark have
agreed for a period of 90 days after the date of this Prospectus, that they
will not offer, sell or otherwise dispose of shares of Common Stock without
the prior written consent of CS First Boston Corporation.
 
  Newpark has agreed to indemnify the Underwriters against certain
liabilities, including civil liabilities under the Securities Act, or
contribute to payments which the Underwriters may be required to make in
respect thereof.

                         NOTICE TO CANADIAN RESIDENTS
 
RESALE RESTRICTIONS
 
  The distribution of the Shares in Canada is being made only on a private
placement basis exempt from the requirement that Newpark prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of Shares are effected. Accordingly, any resale of the Shares in Canada
must be made in accordance with applicable securities laws which will vary
depending on the relevant jurisdiction, and which may require resales to be
made in accordance with available statutory exemptions or pursuant to a
discretionary exemption granted by the applicable Canadian securities
regulatory authority. Purchasers are advised to seek legal advice prior to any
resale of the Shares.
 
REPRESENTATIONS OF PURCHASERS
 
  Each purchaser of Shares in Canada who receives a purchase confirmation will
be deemed to represent to Newpark and the dealer from whom such purchase
confirmation is received that (i) such purchaser is entitled under applicable
provincial securities laws to purchase such Shares without the benefit of a
prospectus qualified under such securities laws, (ii) where required by law,
that such purchaser is purchasing as principal and not as agent, and (iii)
such purchaser has reviewed the text above under "Resale Restrictions".
 
RIGHTS OF ACTION AND ENFORCEMENT
 
  The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by

including common law rights of action for damages or rescission or rights of
action under the civil liability provisions of the U.S. federal securities
laws.
 
  All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be
possible for Ontario purchasers to effect service of process within Canada
upon the issuer or such persons. All or a substantial portion of the assets of
the issuer and such persons may be located outside of Canada and, as a result,
it may not be possible to satisfy a judgment against the issuer or such
persons in Canada or to enforce a judgment obtained in Canadian courts against
such issuer or persons outside of Canada.

                         INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
  Newpark Resources, Inc.
 
  We have audited the accompanying consolidated balance sheets of Newpark
Resources, Inc. and subsidiaries as of December 31, 1995 and 1994, and the
related consolidated statements of income, stockholders' equity and cash flows
for each of the three years in the period ended December 31, 1995. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on the financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Newpark Resources, Inc. and
subsidiaries at December 31, 1995 and 1994, and the results of their
operations and their cash flows for each of the three years in the period
ended December 31, 1995, in conformity with generally accepted accounting
principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Principles of Consolidation. Newpark Resources, Inc.
("Newpark" or the "Company") provides comprehensive environmental management
and oilfield construction services to the oil and gas industry in the Gulf
Coast region, principally Louisiana and Texas. The consolidated financial
statements include the accounts of the Company and its wholly-owned
subsidiaries. All material intercompany transactions are eliminated in
consolidation.
 
  Basis of Presentation. Newpark's interim financial statements as of March
31, 1995 and 1996 include all adjustments which, in the opinion of management,
are necessary in order to make a fair presentation of such financial
statements. All such adjustments are of a normal recurring nature. Operating
results for the three months ended March 31, 1996 are not necessarily
indicative of the results that may be expected for the entire year ending
December 31, 1996.
 
  Use of Estimates. The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities,
the disclosure of contingent assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
  Cash Equivalents. All highly liquid investments with a remaining maturity of
three months or less at the date of acquisition are classified as cash
equivalents.
 
  Fair Value Disclosures. Statement of Financial Accounting Standards ("SFAS")
No. 107, "Disclosures about Fair Value of Financial Instruments", requires the
disclosure of the fair value of all significant financial instruments. The
estimated fair value amounts have been developed based on available market
information and appropriate valuation methodologies. However, considerable
judgment is required in developing the estimates of fair value. Therefore,
such estimates are not necessarily indicative of the amounts that could be
realized in a current market exchange. After such analysis, management
believes the carrying values of the Company's significant financial
instruments (consisting of cash and cash equivalents, receivables, payables
and long-term debt) approximate fair values at March 31, 1996.
 
  Inventories. Inventories are stated at the lower of cost (principally
average and first-in, first-out) or market. The cost of lumber and related
supplies for board roads is amortized on the straight-line method over their
estimated useful life of approximately one year.
 
  Depreciation and Amortization. Depreciation of property, plant and
equipment, including interlocking board road mats, is provided for financial
reporting purposes on the straight-line method over the estimated useful lives
of the individual assets which range from three to thirty years. For income
tax purposes, accelerated methods of depreciation are used.
 
  During the year ended December 31, 1993, the Company made a change in the
estimated service lives of its board road mats from five years to seven years.
The new lives were adopted to recognize the longer service life provided by
the mats. The effect of the change for the year ended December 31, 1993 was to
increase income from continuing operations $1,175,000 ($0.12 per share).
 
  The cost in excess of net assets of purchased businesses ("excess cost") is
being amortized on a straight-line basis over forty years, except for
$2,211,000 relating to acquisitions prior to 1971 that is not being amortized.
Management of Newpark periodically reviews the carrying value of the excess
cost in relation to the current and expected operating results of the
businesses which benefit therefrom in order to assess whether there
 
                                      F-7
<PAGE>
 
has been a permanent impairment of the excess cost of the net purchased
assets. Accumulated amortization on excess cost was $437,000 and $374,000 at
December 31, 1995 and December 31, 1994, respectively.
 
  Revenue Recognition. Revenues from certain contracts, which are typically of
short duration, are reported as income on a percentage-of-completion method.
Contract revenues are recognized in the proportion that costs incurred bear to
the estimated total costs of the contract. When an ultimate loss is
anticipated on a contract, the entire estimated loss is recorded. Included in
accounts receivable are unbilled revenues in the amounts of $8,600,000 and
$2,674,000 at December 31, 1995 and December 31, 1994, respectively, all of
which are due within a one year period.
 
  Income Taxes. Income taxes are provided using the liability method in
accordance with SFAS No. 109, "Accounting for Income Taxes". Under this
method, deferred income taxes are recorded based upon differences between the
financial reporting and income tax basis of assets and liabilities and are
measured using the enacted income tax rates and laws that will be in effect
when the differences are expected to reverse.
 
  Non-Recurring Expense. Results for the year ended December 31, 1995 include
$436,000 of non-recurring costs associated with a proposed merger which was
not completed.
 
  Interest Capitalization. For the years ended December 31, 1995, 1994 and
1993, the Company incurred interest cost of $4,198,000, $2,805,000 and
$1,359,000, respectively, of which $458,000, $145,000 and $85,000,
respectively, was capitalized on qualifying construction projects. For the
three months ended March 31, 1996 and 1995 (unaudited), the Company incurred
interest cost of $2,125,000 and $945,000, respectively, of which $218,000 and
$56,000, respectively, was capitalized.
 
  Income Per Share. Income per share amounts are based on the weighted average
number of shares outstanding during the respective period and exclude the
negligible dilutive effect of shares issuable in connection with all stock
plans. All per share and weighted average share amounts have been restated to
give retroactive effect to a 5% stock dividend declared and paid during 1995.
 
  New Accounting Standards. During 1995, SFAS No. 121 "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of"
was issued. SFAS No. 121 establishes accounting standards for recording the
impairment of long-lived assets, certain identifiable intangibles, goodwill
and assets to be disposed of. The Company's adoption of SFAS No. 121 effective
for 1996 did not have a material impact on the Company's consolidated
financial statements.
 
  In October 1995, SFAS No. 123, "Accounting for Stock-Based Compensation",
was issued and effective for the Company beginning January 1, 1996. SFAS No.
123 requires expanded disclosures of stock-based compensation arrangements
with employees and encourages (but does not require) compensation cost to be
measured based on the fair value of the equity instrument awarded. Companies
are permitted, however, to continue to apply APB Opinion No. 25, which
recognizes compensation cost based on the intrinsic value of the equity
instrument awarded. The Company will continue to apply APB Opinion No. 25 to
its stock based compensation awards to employees and will disclose the
required pro forma effect on net income and earnings per share.
 
  Reclassifications. Certain reclassifications of prior year amounts have been
made to conform to the current year presentation.
 
B. DISCONTINUED OPERATIONS
 
  On December 30, 1993, the operations of the Company's marine service
subsidiary were sold to an unrelated third party for their estimated net book
value of $1,135,000, of which $661,000 was received in cash during 1994 and a
short term note was issued for the remainder. The Company leased the facility
and certain
 
                                      F-8
<PAGE>
 
equipment to the new operator through June 30, 1996, with an option to
purchase these assets at specified times during the lease term. The new
operator has notified Newpark of its intent to exercise the purchase option
before the expiration of the lease term. Newpark also agreed to make available
certain short-term financing of up to $1.6 million through June 30, 1996, with
annual interest at 7%, secured by, among other items, certain assets of the
third party and the personal guarantee of one of its principals. Advances
related to this financing arrangement amounted to $1.6 million at March 31,
1996 (unaudited), $1.6 million at December 31, 1995 and $1.4 million at
December 31, 1994. Revenue of the marine repair business was $16,251,000 for
the year ended December 31, 1993.

  The Company maintains a $60.0 million bank credit facility with $25.0
million in the form of a revolving line of credit commitment and the remaining
$35.0 million in a term note. The line of credit is secured by a pledge of
accounts receivable and certain inventory. It bears interest at either a
specified prime rate (8.5% at December 31, 1995 and 8.25% at March 31, 1996)
or the LIBOR rate (5.63% at December 31, 1995 and 5.44% at March 31, 1996)
plus a spread which is determined quarterly based upon the ratio of the
Company's funded debt to cash flow. The average interest rate for the year
ended December 31, 1995 was 8.56%. The line of credit requires monthly
interest payments and matures on December 31, 1998. At December 31, 1995, $6.3
million of letters of credit were issued and outstanding and $18.4 million had
been borrowed. At March 31, 1996 (unaudited), $5.8 million of letters of
credit were issued and outstanding and $11.6 million had been borrowed,
leaving $19.2 million available for cash advances under the line of credit.
The term note was used to refinance existing debt and requires monthly
interest installments and seventeen equal quarterly principal payments which
commenced March 31, 1996. The term note bears interest at the Company's option
of either a specified prime rate or the LIBOR rate, plus a spread which is
determined quarterly based upon the ratio of the Company's funded debt to cash
flow. The average interest rate for the year ended December 31, 1995 was
8.40%. The credit facility requires that the Company maintain certain
specified financial ratios and comply with other usual and customary
requirements. The Company was in compliance with the agreement at December 31,
1995 and at March 31, 1996.
 
  On December 1, 1995, the Company entered into an interim construction credit
agreement in an aggregate amount not to exceed $1,840,000 for the construction
of an office building for two of its subsidiaries. The outstanding balance of
this credit agreement was $482,000 at December 31, 1995 and $1.8 million at
March 31, 1996 (unaudited). The agreement provides for an interest rate of
8.75% during construction. At the completion of construction, the interim
construction credit agreement will be converted to a term loan. The term loan
will require monthly principal and interest payments to fully amortize the
amount over 10 years. The term note will bear a fixed interest rate of 2.25%
per annum in excess of the treasury rate in effect on the date the term loan
is signed.
 
  Maturities of Long-Term Debt are $7,911,000 in 1996, $7,438,000 in 1997,
$26,067,000 in 1998, $7,638,000 in 1999, $4,941,000 in 2000 and $640,000
thereafter.

  For federal income tax return purposes, the Company has net operating loss
carryforwards ("NOLs") of $22,835,000 (net of amounts disallowed pursuant to
IRC Section 382) that, if not used, will expire in 1998 through 2009. The
Company also has $1,592,000 of alternative minimum tax credit carryforwards
available to offset future regular income taxes subject to certain
limitations. Substantially all of these carryforwards have been recognized for
financial reporting purposes.

  Under SFAS No. 109, a valuation allowance must be established to offset a
deferred tax asset if, based on the weight of available evidence, it is more
likely than not that some portion or all of the deferred tax asset will
 
                                     F-11
<PAGE>
 
not be realized. At December 31, 1994, the Company evaluated the available
evidence and believed that it was more likely than not that a portion of the
deferred tax asset would not be realized. A valuation allowance was recorded
in the financial statements to offset NOLs which the Company believed would
not be utilized. At December 31, 1994, the Company recorded a net deferred tax
asset of $1,900,000, of which $2,271,000 was recorded in non-current assets
and $371,000 was recorded in current accrued liabilities, the realization of
which was dependent on the Company's ability to generate taxable income in
future periods. The Company believed that its estimate of future earnings
based on contracts in place, the overall improved gas market and its prior
earnings trend supported the recorded net deferred tax asset.
 
  At December 31, 1995, the deferred tax liabilities of the consolidated group
exceeded the deferred tax assets, therefore a deferred tax benefit was
recorded for the full amount of the remaining federal NOLs. The valuation
allowance recorded at December 31, 1995 relates to certain state NOLs which
have not to date been recognized for financial reporting purposes. At December
31, 1995, the Company has recorded a net deferred tax liability of $1,317,000,
of which $2,701,000 has been recorded in other current assets and $4,018,000
has been recorded as long-term deferred taxes payable.

  At December 31, 1995 and December 31, 1994, the total number of outstanding
exercisable options were 145,979 and 54,144, respectively.
 
  The 1992 Directors' Stock Option Plan (the "1992 Directors' Plan") was
adopted on October 21, 1992 by the Compensation Committee and was approved by
the stockholders in 1993.
 
  The purpose of the 1992 Directors' Plan was to provide two directors
("Optionees") additional compensation for their services to Newpark and to
promote an increased incentive and personal interest in the welfare of Newpark
by such directors. The Optionees were each granted a stock option to purchase
52,500 shares of Common Stock at an exercise price of $8.33 per share, the
fair market value of the Common Stock on the date of grant, for a term of ten
years. No additional options may be granted under the Directors' Plan. At
December 31, 1995, 52,500 options had been exercised under this plan.
 
  The 1993 Non-Employee Directors' Stock Option Plan (the "1993 Non-Employee
Directors' Plan") was adopted on September 1, 1993 by the Board of Directors
and was approved by the stockholders in 1994.
 
  The 1993 Non-Employee Directors' Plan is intended to allow each non-employee
director of Newpark to purchase 15,750 shares of Common Stock. Non-employee
directors are not eligible to participate in any other stock option or similar
plan currently maintained by Newpark. The purpose of the 1993 Non-Employee
Directors' Plan is to promote an increased incentive and personal interest in
the welfare of Newpark by those individuals who are primarily responsible for
shaping the long-range plans of Newpark, to assist Newpark in attracting and
retaining on the Board persons of exceptional competence and to provide
additional incentives to serve as a director of Newpark.
 
  Upon the adoption of the 1993 Non-Employee Directors' Plan, the five non-
employee directors then serving were each granted a stock option to purchase
15,750 shares of Common Stock at an exercise price of $8.57 per share, the
fair market value of the Common Stock on the date of grant. In addition, each
new Non-Employee Director, on the date of his or her election to the Board of
Directors, automatically will be granted a stock option to purchase 15,750
shares of Common Stock at an exercise price equal to the fair market value of
the Common Stock on the date of grant. The determination of fair market value
of the Common Stock is based on market quotations. On November 2, 1995, the
Board of Directors adopted, subject to stockholder approval, amendments to the
Non-Employee Directors' Plan to increase the maximum number of shares issuable
thereunder from 157,500 to 210,000 and to provide for the automatic grant at
five year intervals of additional stock options to purchase 10,500 shares of
Common Stock to each non-employee director who continues to serve on the
Board. At December 31, 1995, 15,750 options had been exercised under the 1993
Non-Employee Directors' Plan.
 
  On November 2, 1995, the Board of Directors adopted, subject to stockholder
approval, the Newpark Resources, Inc. 1995 Incentive Stock Option Plan (the
"1995 Plan"), pursuant to which the Compensation
 
                                     F-13
<PAGE>
 
Committee may grant incentive stock options and nonstatutory stock options to
designated employees of Newpark. Initially, a maximum of 525,000 shares of
Common Stock may be issued under the 1995 Plan, with such maximum number
increasing on the last business day of each fiscal year of Newpark, commencing
with the last business day of the fiscal year ending December 31, 1996, by a
number equal to 1.25% of the number of shares of Common Stock issued and
outstanding on the close of business on such date, with a maximum number of
shares of Common Stock that may be issued upon exercise of options granted
under the 1995 Plan being limited to 1,312,500.
 
I. SUPPLEMENTAL CASH FLOW INFORMATION

the sale of the operations of the Company's marine repair business for
$661,000 in cash and a $400,000 note receivable.
 
  During 1993, the Company's noncash transactions included the issuance of

J. COMMITMENTS AND CONTINGENCIES
 
  Newpark and its subsidiaries are involved in litigation and other claims or
assessments on matters arising in the normal course of business. In the
opinion of management, any recovery or liability in these matters will not
have a material adverse effect on Newpark's consolidated financial statements.
 
  During 1992, the State of Texas assessed additional sales taxes for the
years 1988-1991. The Company has filed a petition for redetermination with the
Comptroller of Public Accounts. The Company believes that the ultimate
resolution of this matter will not have a material adverse effect on the
consolidated financial statements.
 
  In the normal course of business, in conjunction with its insurance
programs, the Company has established letters of credit in favor of certain
insurance companies in the amount of $2,000,000 at March 31, 1996 (unaudited),
and $2,825,000 at December 31, 1995 and December 31, 1994. At December 31,
1995 and March 31, 1996 (unaudited), the Company had outstanding guaranty
obligations totaling $469,000 and $453,000, respectively, in connection with
facility closure bonds issued by an insurance company.
 
  Since May 1988, the Company has held the exclusive right to use a patented
prefabricated mat system with respect to the oil and gas exploration and
production industry within the State of Louisiana. On June 20, 1994, the
Company entered into a new license agreement by which it obtained the
exclusive right to use the same patented prefabricated mat system, without
industry restriction, throughout the continental United States. The license
agreement requires, among other things, that the company purchase a minimum of
20,000 mats annually
 
                                     F-14
<PAGE>
 
through 2003. The Company has met this annual mat purchase requirement since
the inception of the agreement. Any purchases in excess of that level may be
applied to future annual requirements. The Company's annual commitment to
maintain the agreement in force is currently estimated to be $4,600,000.
 
  At December 31, 1995 and March 31, 1996 (unaudited), the Company had
outstanding a letter of credit in the amount of $3,816,000 issued to a state
regulatory agency to assure funding for future site closure obligations at its
NORM processing facility.
 
  The Company leases various manufacturing facilities, warehouses, office
space, machinery and equipment and transportation equipment under operating
leases with remaining terms ranging from one to ten years with various renewal
options. Substantially all leases require payment of taxes, insurance and
maintenance costs in addition to rental payments. Total rental expenses of
continuing operations for all operating leases were $5,210,000, $4,049,000 and
$4,226,000, in 1995, 1994 and 1993, respectively.
 
  Future minimum payments under noncancelable operating leases, with initial
or remaining terms in excess of one year are: $1,683,000 in 1996; $1,192,000
in 1997; $924,000 in 1998; $859,000 in 1999; $781,000 in 2000; and $562,000
thereafter.
 
  Capital lease commitments are not significant.
 
K. BUSINESS AND CREDIT CONCENTRATION
 
  During 1995, one customer accounted for approximately 16% of total revenue
($15,890,000). In 1993 and 1994, the Company did not derive ten percent or
more of its revenues from sales to any single customer.
 
  Export sales are not significant.
 
L. CONCENTRATIONS OF CREDIT RISK
 
  Financial instruments which potentially subject the Company to significant
concentrations of credit risk consist principally of cash investments and
trade accounts and notes receivable.
 
  The Company maintains cash and cash equivalents with various financial
institutions. These financial institutions are located throughout the
Company's trade area and company policy is designed to limit exposure to any
one institution. The Company performs periodic evaluations of the relative
credit standing of these financial institutions which are considered in the
Company's investment strategy.
 
  Concentrations of credit risk with respect to trade accounts and notes
receivable are limited due to the large number of entities comprising the
Company's customer base and, for notes receivable, the required collateral.
The Company maintains an allowance for losses based upon the expected
collectibility of accounts and notes receivable.

                          INDEPENDENT AUDITORS REPORT
 
To the Board of Directors
Sanifill, Inc.
 
  We have audited the accompanying statements of net assets of the marine NOW
service business of Campbell Wells, Ltd. (the "Acquired Business") as of
December 31, 1995 and 1994, and the related statements of operations for each
of the three years in the period ended December 31, 1995. These financial
statements are the responsibility of the management of Campbell Wells, Ltd.
Our responsibility is to express an opinion on these financial statements
based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, such financial statements present fairly, in all material
respects, the statements of net assets of the Acquired Business, as of
December 31, 1995 and 1994, and the results of operations of the Acquired
Business for each of the three years in the period ended December 31, 1995 in
conformity with generally accepted accounting principles.

               CAMPBELL WELLS, LTD.--MARINE NOW SERVICE BUSINESS
 
                         NOTES TO FINANCIAL STATEMENTS
 
A. BASIS OF PRESENTATION
 
  On June 5, 1996, Newpark Resources, Inc. ("Newpark") entered into an Asset
Purchase and Lease Agreement with Sanifill, Inc. ("Sanifill") and Campbell
Wells Ltd. ("Campbell Wells"), a wholly owned subsidiary of Sanifill, for the
purchase and lease of certain marine related assets of the nonhazardous
oilfield waste ("NOW") service business of Campbell Wells (the "Acquired
Business"). If the transaction is consummated, Newpark will purchase
substantially all of Campbell Wells non-landfarm assets and will assume leases
associated with five transfer stations located along the Gulf Coast and three
receiving docks at the landfarm facilities operated by Campbell Wells. The
accompanying financial statements have been prepared from the historical books
and records of Campbell Wells and present (1) the assets of the Acquired
Business as of December 31, 1995 and 1994 and (2) the results of operations of
the Acquired Business for the years ended December 31, 1995, 1994, and 1993.
Since only certain net assets are being acquired, statements of financial
position and cash flows of the marine related NOW service business are not
applicable.
 
  The statements of operations may not necessarily be indicative of the
results of operations that would have been realized had the Acquired Business
been operated as a stand-alone entity or as an unaffiliated entity. The
statements of operations include an allocation of selling, general and
administrative expense based on a percentage of revenues. Campbell Wells
believes this allocation is reasonable.
 
  As a wholly owned subsidiary of Sanifill, Campbell Wells maintained a
noninterest-bearing intercompany account with Sanifill for recording the
parent company's investment, intercompany charges for costs and expenses, and
intercompany transfers of cash, among other transactions. It is not feasible
to ascertain the portion of the intercompany account related solely to the
Acquired Business, and, consequently, the amount of related interest expense
or interest income which would have been recorded in the accompanying
statements of operations had the intercompany account been interest-bearing.
 
B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Use of Estimates--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities,
the disclosure of contingent assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
  Property and Equipment--Property and equipment are stated at cost, less
accumulated depreciation. Expenditures for property and equipment and items
which substantially increase the useful lives of existing assets are
capitalized at cost and depreciated. Depreciation is provided using the
straight-line method in amounts considered sufficient to amortize the cost of
the depreciable assets to operations over their estimated services lives.
Leasehold improvements are amortized over the lives of the respective leases
or their estimated service lives, whichever is shorter. Equipment leased under
capital leases is amortized over the normal depreciation policy for owned
assets. Depreciation expense for each of the three years in the period ended
December 31, 1995 was approximately $194,000, $150,000 and $116,000,
respectively. The periods used in determining depreciation and amortization
follow:
 
<TABLE>
<CAPTION>
                                        PERIOD
                                      -----------
<S>                                   <C>
Buildings and leasehold improvements  10-30 years
Vehicles and equipment                  3-7 years
Furniture and fixtures                  3-7 years
</TABLE>
 
  Differences in useful lives are due to differences in lease terms or
estimated lives for the different locations.
 
                                     F-20
<PAGE>
 
  Revenue Recognition--Revenues in the Acquired Business are primarily
comprised of disposal and barge cleaning fees. Disposal revenue is recognized
once the waste is unloaded at the disposal or transfer facility.
 
  Income Taxes--The operations of Campbell Wells and the Acquired Business
were included in the consolidated U.S. federal income tax return of Sanifill,
Inc. Campbell Wells, Ltd. assumed a federal tax rate of 34% of taxable income.
The allocation did not distinguish between current and deferred income taxes.
State income taxes were not material.
 
C. LEASE COMMITMENTS
 
  In the operation of the Acquired Business, Campbell Wells leases various
barges and tug boats, machinery and equipment, and transfer facilities under
operating leases with remaining terms ranging from one to five years with
various renewal options. Substantially all leases require payment of taxes,
insurance and maintenance costs in addition to rental payments. Total rental
expenses for all operating leases were approximately $1,862,000, $2,245,000
and $2,011,000 for the years ended December 31, 1995, 1994 and 1993,
respectively.
 
  Future minimum payments under noncancelable operating leases with initial or
remaining terms in excess of one year are $895,000 in 1996, $419,000 in 1994,
$346,000 in 1998, $347,000 in 1999 and $237,000 in 2000.
 
  Property plant and equipment at December 31 includes the following amounts
related to capital leases:

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.
 
  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
 
                                     II-1
<PAGE>
 
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 undersigned 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 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.
 
                                     II-2
<PAGE>
 
    (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.
 
  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
relating 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.

CS FIRST BOSTON CORPORATION
DEUTSCHE MORGAN GRENFELL/C. J. LAWRENCE INC.
THE ROBINSON-HUMPHREY COMPANY, INC.
JEFFERIES & COMPANY, INC.,
 As Representatives of the Several Underwriters,
  c/o CS First Boston Corporation,
   Park Avenue Plaza,
   New York, N.Y. 10055.

Ladies and Gentlemen:

     1.  Introductory.  Newpark Resources, Inc., a Delaware corporation (the
"Company"), proposes to issue and sell 3,000,000 shares (the "Firm Securities")
of its common stock, $.01 par value (the "Securities"), and also proposes to
issue and sell to the Underwriters, at the option of the Underwriters, an
aggregate of not more than 450,000 additional shares (the "Optional Securities")
of its Securities as set forth below.  The Firm Securities and the Optional
Securities are herein collectively called the "Offered Securities".  The Company
hereby agrees with the several Underwriters named in Schedule A hereto (the
"Underwriters") as follows:

     2.  Representations and Warranties of the Company.  The Company represents
and warrants to, and agrees with, the several Underwriters that:

     (a)  A registration statement (No. 333-05805) relating to the Offered
Securities, including a form of prospectus, has been filed with the Securities
and Exchange Commission (the "Commission") and either  has been declared
effective under the Securities Act of 1933 (the "Act") and is not proposed to be
amended or  is proposed to be amended by amendment or post-effective amendment.
If such registration statement (the "initial registration statement") has been
declared effective, either (i) an additional registration statement (the
"additional registration statement") relating to the Offered Securities may have
been filed with the Commission pursuant to Rule 462(b) ("Rule 462(b)") under the
Act and, if so filed, has become effective upon filing pursuant to Rule 462(b)
and the Offered Securities all have been duly registered under the Act pursuant
to the initial registration statement and, if applicable, the additional
registration statement or (ii) such an additional registration statement is
proposed to be filed with the Commission pursuant to Rule 462(b) and will become
effective upon filing pursuant to Rule 462(b) and upon such filing the Offered
Securities will all have been duly registered under the Act pursuant to the
<PAGE>
 
initial registration statement and such additional registration statement. If
the Company does not propose to amend the initial registration statement or if
an additional registration statement has been filed and the Company does not
propose to amend it, and if any post-effective amendment to either such
registration statement has been filed with the Commission prior to the execution
and delivery of this Agreement, the most recent amendment (if any) to each such
registration statement has been declared effective by the Commission or has
become effective upon filing pursuant to Rule 462(c) ("Rule 462(c)") under the
Act or, in the case of the additional registration statement, Rule 462(b). For
purposes of this Agreement, "Effective Time" with respect to the initial
registration statement or, if filed prior to the execution and delivery of this
Agreement, the additional registration statement means (i) if the Company has
advised the Representatives that it does not propose to amend such registration
statement, the date and time as of which such registration statement, or the
most recent post-effective amendment thereto (if any) filed prior to the
execution and delivery of this Agreement, was declared effective by the
Commission or has become effective upon filing pursuant to Rule 462(c), or (ii)
if the Company has advised the Representatives that it proposes to file an
amendment or post-effective amendment to such registration statement, the date
and time as of which such registration statement, as amended by such amendment
or post-effective amendment, as the case may be, is declared effective by the
Commission. If an additional registration statement has not been filed prior to
the execution and delivery of this Agreement but the Company has advised the
Representatives that it proposes to file one, "Effective Time" with respect to
such additional registration statement means the date and time as of which such
registration statement is filed and becomes effective pursuant to Rule 462(b).
"Effective Date" with respect to the initial registration statement or the
additional registration statement (if any) means the date of the Effective Time
thereof. The initial registration statement, as amended at its Effective Time,
including all material incorporated by reference therein, including all
information contained in the additional registration statement (if any) and
deemed to be a part of the initial registration statement as of the Effective
Time of the additional registration statement pursuant to the General
Instructions of the Form on which it is filed and including all information (if
any) deemed to be a part of the initial registration statement as of its
Effective Time pursuant to Rule 430A(b) ("Rule 430A(b)") under the Act, is
hereinafter referred to as the "Initial Registration Statement". The additional
registration statement, as amended at its Effective Time, including the contents
of the initial registration statement incorporated by reference therein and
including all information (if any) deemed to be a part of the additional
registration statement as of its Effective Time pursuant to Rule 430A(b), is
hereinafter referred to as the "Additional Registration Statement". The Initial
Registration Statement and the Additional Registration Statement are hereinafter
referred to collectively as the "Registration Statements" and individually as a
"Registration Statement". The form of prospectus relating to the Offered
Securities, as first filed with the Commission pursuant to and in accordance
with Rule 424(b) ("Rule 424(b)") under the Act or (if no such filing is
required) as included in the Registration Statement, including all material
incorporated by reference in such prospectus, is hereinafter referred to as the
"Prospectus". No document has been or will be prepared or distributed in
reliance on Rule 434 under the Act.

     (b) If the Effective Time of the Initial Registration Statement is prior to
the execution and delivery of this Agreement (i) on the Effective Date of the
Initial Registration Statement, the Initial Registration Statement conformed in
all material respects to the applicable requirements of the Act and the rules
and regulations of the Commission (the "Rules and Regulations") and did not
include any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading, (ii) on the Effective Date of the Additional Registration
Statement (if any), each Registration Statement 

                                       2
<PAGE>
 
conformed, or will conform, in all material respects to the applicable
requirements of the Act and the Rules and Regulations and did not include, or
will not include, any untrue statement of a material fact and did not omit, or
will not omit, to state any material fact required to be stated therein or
necessary to make the statements therein not misleading and (iii) on the date of
this Agreement, the Initial Registration Statement and, if the Effective Time of
the Additional Registration Statement is prior to the execution and delivery of
this Agreement, the Additional Registration Statement each conforms, and at the
time of filing of the Prospectus pursuant to Rule 424(b) or (if no such filing
is required) at the Effective Date of the Additional Registration Statement in
which the Prospectus is included, each Registration Statement and the Prospectus
will conform, in all material respects to the applicable requirements of the Act
and the Rules and Regulations, and none of such documents includes, or will
include, any untrue statement of a material fact or omits, or will omit, to
state any material fact required to be stated therein or necessary to make the
statements therein (and, in the case of the Prospectus, in light of the
circumstances under which they were made) not misleading. If the Effective Time
of the Initial Registration Statement is subsequent to the execution and
delivery of this Agreement, on the Effective Date of the Initial Registration
Statement, the Initial Registration Statement and the Prospectus will conform in
all material respects to the applicable requirements of the Act and the Rules
and Regulations, neither of such documents will include any untrue statement of
a material fact or will omit to state any material fact required to be stated
therein or necessary to make the statements therein (and, in the case of the
Prospectus, in light of the circumstances under which they were made) not
misleading, and no Additional Registration Statement has been or will be filed.
The two preceding sentences do not apply to statements in or omissions from a
Registration Statement or the Prospectus (or any supplements thereto) based upon
written information furnished to the Company by any Underwriter through the
Representatives specifically for use therein, it being understood and agreed
that the only such information is that described as such in Section 7(b).

     (c) The Company has been duly incorporated and is an existing corporation
in good standing under the laws of the State of Delaware, with power and
authority (corporate and other) to own its properties and conduct its business
as described in the Prospectus; and the Company is duly qualified to do business
as a foreign corporation in good standing in all other jurisdictions in which
its ownership or lease of property or the conduct of its business requires such
qualification and in which the failure, individually or in the aggregate, to be
so qualified would have a material adverse effect on the Company.

     (d) Each subsidiary of the Company has been duly incorporated and is an
existing corporation in good standing under the laws of the jurisdiction of its
incorporation, with power and authority (corporate and other) to own its
properties and conduct its business as described in the Prospectus; and each
subsidiary of the Company is duly qualified to do business as a foreign
corporation in good standing in all other jurisdictions in which its ownership
or lease of property or the conduct of its business requires such qualification
and in which the failure, individually or in the aggregate, to be so qualified
would have a material adverse effect on the Company and its subsidiaries, taken
as a whole; all of the issued and outstanding capital stock of each subsidiary
of the Company has been duly authorized and validly issued and is fully paid and
nonassessable; and the capital stock of each subsidiary owned by the Company,
directly or through subsidiaries, is owned free from liens, encumbrances and
defects.

     (e) The Offered Securities and all other outstanding shares of capital
stock of the Company have been duly authorized; all outstanding shares of
capital stock of the Company are, 

                                       3
<PAGE>
 
and, when the Offered Securities have been delivered and paid for in accordance
with this Agreement on each Closing Date (as defined below), such Offered
Securities will have been, validly issued, fully paid and nonassessable and will
conform to the description thereof contained in the Prospectus; and the
stockholders of the Company have no preemptive rights with respect to the
Securities.

     (f) Except as disclosed in the Prospectus, there are no contracts,
agreements or understandings between the Company and any person that would give
rise to a valid claim against the Company or any Underwriter for a brokerage
commission, finder's fee or other like payment.

     (g) There are no contracts, agreements or understandings between the
Company and any person granting such person the right to require the Company to
file a registration statement under the Act with respect to any securities of
the Company owned or to be owned by such person or to require the Company to
include such securities in the securities registered pursuant to a Registration
Statement or in any securities being registered pursuant to any other
registration statement filed by the Company under the Act (other than the
Company's obligation to register shares of the Securities issuable under its
employee benefit plans).

     (h) The Offered Securities have been approved for listing on The New York
Stock Exchange, subject to notice of issuance.

     (i) No consent, approval, authorization, or order of, or filing with, any
governmental agency or body or any court is required for the consummation of the
transactions contemplated by this Agreement in connection with the issuance and
sale of the Offered Securities by the Company, except such as have been obtained
and made and registration of the Offered Securities under the Act and such as
may be required under state securities laws.

     (j) The execution, delivery and performance of this Agreement, and the
issuance and sale of the Offered Securities will not result in a breach or
violation of any of the terms and provisions of, or constitute a default under,
any statute, any rule, regulation or order of any governmental agency or body or
any court, domestic or foreign, having jurisdiction over the Company or any
subsidiary of the Company or any of their properties, or any agreement or
instrument to which the Company or any such subsidiary is a party or by which
the Company or any such subsidiary is bound or to which any of the properties of
the Company or any such subsidiary is subject, or the charter or by-laws of the
Company or any such subsidiary, which breach, violation or default would,
individually or in the aggregate, have a material adverse effect on the Company
and its subsidiaries, taken as a whole, and the Company has full power and
authority to authorize, issue and sell the Offered Securities as contemplated by
this Agreement.

     (k) This Agreement has been duly authorized, executed and delivered by the
Company.

     (l) Except as disclosed in the Prospectus, the Company and its subsidiaries
have good and marketable title to all real properties and all other properties

that would materially affect the value thereof or materially interfere with the
use made or to be made thereof by them; and except as disclosed in the
Prospectus, the Company and its subsidiaries hold any leased real or personal
property under valid and enforceable leases with no exceptions that would
materially interfere with the use made or to be made thereof by them.

                                       4

     (m) The Company and its subsidiaries possess adequate certificates,
authorities or permits issued by appropriate governmental agencies or bodies
necessary to conduct the business now operated by them, except for certificates,
authorities or permits that are not material and do not interfere with the
conduct of the business of the Company and its subsidiaries, taken as a whole.
The Company and its subsidiaries have not received any notice of proceedings
relating to the revocation or modification of any such certificate, authority or
permit that, if determined adversely to the Company or any of its subsidiaries,
would individually or in the aggregate have a material adverse effect on the
Company and its subsidiaries taken as a whole.

     (n) No labor dispute with the employees of the Company or any subsidiary
exists or, to the knowledge of the Company, is imminent that might have a
material adverse effect on the Company and its subsidiaries taken as a whole.

     (o) The Company and its subsidiaries own, possess or can acquire on
reasonable terms, adequate trademarks, trade names and other rights to
inventions, know-how, patents, copyrights, confidential information and other
intellectual property (collectively, "intellectual property rights") necessary
to conduct the business now operated by them, or currently employed by them,
except for intellectual property rights that are not material and do not
interfere with the conduct of the business of the Company and its subsidiaries,
taken as a whole.  The Company and its subsidiaries have not received any notice
of infringement of or conflict with asserted rights of others with respect to
any intellectual property rights that, if determined adversely to the Company or
any of its subsidiaries, would individually or in the aggregate have a material
adverse effect on the Company and its subsidiaries taken as a whole.

     (p) Except as disclosed in the Prospectus, neither the Company nor any of
its subsidiaries is in violation of any statute, any rule, regulation, decision
or order of any governmental agency or body or any court, domestic or foreign,
relating to the use, disposal or release of hazardous or toxic substances or
relating to the protection or restoration of the environment or human exposure
to hazardous or toxic substances  (collectively, "environmental laws"), owns or
operates any real property contaminated with any substance that is subject to
any environmental laws, is liable for any off-site disposal or contamination
pursuant to any environmental laws, or is subject to any claim relating to any
environmental laws, which violation, contamination, liability or claim would
individually or in the aggregate have a material adverse effect on the Company
and its subsidiaries taken as a whole; and the Company is not aware of any
pending investigation which might lead to such a claim.

     (q) Except as disclosed in the Prospectus, there are no pending actions,
suits or proceedings against or affecting the Company, any of its subsidiaries
or any of their respective properties that, if determined adversely to the
Company or any of its subsidiaries, would individually or in the aggregate have
a material adverse effect on the condition (financial or other), business,
properties or results of operations of the Company and its subsidiaries taken as
a whole, or would materially and adversely affect the ability of the Company to
perform its obligations under this Agreement, or that are otherwise material in
the context of the sale of the Offered Securities; and no such actions, suits or
proceedings are, to the Company's knowledge, threatened or contemplated.

     (r) The financial statements included in each Registration Statement and

consolidated subsidiaries as of the dates shown and their results of operations
and cash flows for the periods shown 

                                       5
<PAGE>
 
(subject in the case of the financial statements for interim periods, to normal
and recurring year-end adjustments), and such financial statements have been
prepared in conformity with the generally accepted accounting principles in the
United States applied on a consistent basis, the schedules included in each
Registration Statement present fairly the information required to be stated
therein; and the assumptions used in preparing the pro forma financial
statements included in each Registration Statement and Prospectus provide a
reasonable basis for presenting the significant effects directly attributable to
the transactions or events described therein, the related pro forma adjustments
give appropriate effect to those assumptions, and the pro forma columns therein
reflect the proper application of those adjustments to the corresponding
historical financial statement amounts.

     (s) Except as disclosed in the Prospectus, since the date of the latest
audited financial statements included in the Prospectus there has been no
material adverse change, nor any development or event involving a prospective
material adverse change, in the condition (financial or other), business,
properties or results of operations of the Company and its subsidiaries taken as
a whole, and, except as disclosed in or contemplated by the Prospectus, there
has been no dividend or distribution of any kind declared, paid or made by the
Company on any class of its capital stock.

     (t) The Company is not and, after giving effect to the offering and sale of
the Offered Securities and the application of the proceeds thereof as described
in the Prospectus, will not be an "investment company" as defined in the
Investment Company Act of 1940.

     (u) Neither the Company nor any of its affiliates does business with the
government of Cuba or with any person or affiliate located in Cuba within the
meaning of Section 517.075, Florida Statutes and the Company agrees to comply
with such Section if prior to the completion of the distribution of the Offered
Securities it commences doing such business.

     3.  Purchase, Sale and Delivery of Offered Securities.  On the basis of the
representations, warranties and agreements herein contained, but subject to the
terms and conditions herein set forth, the Company agrees to sell to the
Underwriters, and the Underwriters agree, severally and not jointly, to purchase
from the Company, at a purchase price of $       per share, the respective
numbers of shares of the Firm Securities set forth opposite the names of the
Underwriters in Schedule A hereto.

     The Company will deliver the Firm Securities to the Representatives for the
accounts of the Underwriters, at the office of CS First Boston Corporation ("CS
First Boston"), Park Avenue Plaza, New York, New York 10055, against payment of
the purchase price in funds available on the same day by wire transfer to the
account of the Company at a bank acceptable to CS First Boston or by official
Federal Reserve Bank check or checks drawn to the order of the Company at the
office of Fulbright & Jaworski L.L.P., 1301 McKinney, Suite 5100, Houston, Texas
77010, at 10:00 A.M., New York time, on August     1996, or at such other time
not later than seven full business days thereafter as CS First Boston and the
Company determine, such time being herein referred to as the "First Closing
Date").  For purposes of Rule 15c6-1 under the Securities Exchange Act of 1934,
the First Closing Date (if later than the otherwise applicable settlement date)
shall be the settlement date for payment of funds and delivery of securities for
all the Offered Securities sold pursuant to the offering.  The certificates for
the Firm Securities so to be delivered will be in definitive form, in such
denominations and registered in such names as CS First Boston requests upon
reasonable notice and will be made available for checking and packaging at the
above office of CS First Boston, at least 24 hours prior to the First Closing
Date.

                                       6
<PAGE>
 
     In addition, upon written notice from CS First Boston given to the Company
from time to time not more than 30 days subsequent to the date of the
Prospectus, the Underwriters may purchase all or less than all of the Optional
Securities at the purchase price per Security to be paid for the Firm
Securities.  The Company agrees to sell to the Underwriters the number of shares
of Optional Securities specified in such notice and the Underwriters agree,
severally and not jointly, to purchase such Optional Securities.  Such Optional
Securities shall be purchased for the account of each Underwriter in the same
proportion as the number of shares of Firm Securities set forth opposite such
Underwriter's name bears to the total number of shares of Firm Securities
(subject to adjustment by CS First Boston to eliminate fractions) and may be
purchased by the Underwriters only for the purpose of covering over-allotments
made in connection with the sale of the Firm Securities.  No Optional Securities
shall be sold or delivered unless the Firm Securities previously have been, or
simultaneously are, sold and delivered.  The right to purchase the Optional
Securities or any portion thereof may be exercised from time to time and to the
extent not previously exercised may be surrendered and terminated at any time
upon notice by CS First Boston to the Company.

     Each time for the delivery of and payment for the Optional Securities,
being herein referred to as an "Optional Closing Date", which may be the First
Closing Date (the First Closing Date and each Optional Closing Date, if any,
being sometimes referred to as a "Closing Date"), shall be determined by CS
First Boston but shall be not later than five full business days after written
notice of election to purchase Optional Securities is given.  The Company will
deliver the Optional Securities being purchased on each Optional Closing Date to
the Representatives for the accounts of the several Underwriters, at the office
of CS First Boston, Park Avenue Plaza, New York, N.Y. 10055, against payment of
the purchase price therefor in funds available on the same day by wire transfer
to the account of the Company at a bank acceptable to CS First Boston or by
official Federal Reserve Bank check or checks drawn to the order of the Company,
at the above office of Fulbright & Jaworski L.L.P.  The certificates for the
Optional Securities will be in definitive form, in such denominations and
registered in such names as CS First Boston requests upon reasonable notice
prior to such Optional Closing Date and will be made available for checking and
packaging at the above office of CS First Boston, at a reasonable time in
advance of such Optional Closing Date.

     4.  Offering by Underwriters.  It is understood that the several
Underwriters propose to offer the Offered Securities for sale to the public as
set forth in the Prospectus.

     5.  Certain Agreements of the Company.  The Company agrees with the several
Underwriters that:

     (a) If the Effective Time of the Initial Registration Statement is prior to
the execution and delivery of this Agreement, the Company will file the
Prospectus with the Commission pursuant to and in accordance with subparagraph
(1) (or, if applicable and if consented to by CS First Boston, subparagraph (4))
of Rule 424(b) not later than the earlier of (A) the second business day
following the execution and delivery of this Agreement or (B) the fifteenth
business day after the Effective Date of the Initial Registration Statement.

     The Company will advise CS First Boston promptly of any such filing
pursuant to Rule 424(b).  If the Effective Time of the Initial Registration
Statement is prior to the execution and delivery of this Agreement and an
additional registration statement is necessary to register a portion of the
Offered Securities under the Act but the Effective Time thereof has not occurred
as of such execution and delivery, the Company will file the additional
registration statement or, if filed, will file a post-effective amendment
thereto with the Commission pursuant to and in 

                                       7
<PAGE>
 
accordance with Rule 462(b) on or prior to 10:00 P.M., New York time, on the
date of this Agreement or, if earlier, on or prior to the time the Prospectus is
printed and distributed to any Underwriter, or will make such filing at such
later date as shall have been consented to by CS First Boston.

     (b) The Company will advise CS First Boston promptly of any proposal to
amend or supplement the initial or any additional registration statement as
filed or the related prospectus or the Initial Registration Statement, the
Additional Registration Statement (if any) or the Prospectus and will not effect
such amendment or supplementation without CS First Boston's prior consent; and
the Company will also advise CS First Boston promptly of the effectiveness of
each Registration Statement (if its Effective Time is subsequent to the
execution and delivery of this Agreement) and of any amendment or
supplementation of a Registration Statement or the Prospectus and of the
institution by the Commission of any stop order proceedings in respect of a
Registration Statement and will use its best efforts to prevent the issuance of
any such stop order and to obtain as soon as possible its lifting, if issued.

     (c) If, at any time when a prospectus relating to the Offered Securities is
required to be delivered under the Act in connection with sales by any
Underwriter or dealer, any event occurs as a result of which the Prospectus as
then amended or supplemented would include an untrue statement of a material
fact or omit to state any material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, or if it is necessary at any time to amend or supplement the
Prospectus to comply with the Act, the Company will promptly notify CS First
Boston of such event and will promptly prepare and file with the Commission, at
its own expense, an amendment or supplement that will correct such statement or
omission or an amendment that will effect such compliance.  Neither CS First
Boston's consent to, nor the Underwriters' delivery of, any such amendment or
supplement shall constitute a waiver of any of the conditions set forth in
Section 6.

     (d) As soon as practicable, but not later than the Availability Date (as
defined below), the Company will make generally available to its security
holders an earnings statement covering a period of at least 12 months beginning
after the Effective Date of the Initial Registration Statement (or, if later,
the Effective Date of the Additional Registration Statement) that will satisfy
the provisions of Section 11(a) of the Act.  For the purpose of the preceding
sentence, "Availability Date" means the 45th day after the end of the fourth
fiscal quarter following the fiscal quarter that includes such Effective Date,
except that, if such fourth fiscal quarter is the last quarter of the Company's
fiscal year, "Availability Date" means the 90th day after the end of such fourth
fiscal quarter.

     (e) The Company will furnish to the Representatives copies of the
Registration Statement (five of which will be signed and will include all
exhibits), each preliminary prospectus, and, so long as delivery of a prospectus
relating to the Offered Securities is required to be delivered under the Act in
connection with sales by any Underwriter or dealer, the Prospectus and all
amendments and supplements to such documents, in each case in such quantities as
CS First Boston requests.  The Prospectus shall be so furnished on or prior to
3:00 P.M., New York time, on the business day following the later of the
execution and delivery of this Agreement or the Effective Time of the Initial
Registration Statement.  All other documents shall be so furnished as soon as
available.  The Company will pay the expenses of printing and distributing to
the Underwriters all such documents.

                                       8
<PAGE>
 
     (f) The Company will arrange for the qualification of the Offered
Securities for sale under the laws of such jurisdictions in the United States as
CS First Boston designates and will continue such qualifications in effect so
long as required for the distribution, provided that the Company shall not be
required to qualify as a foreign corporation or to consent to service of process
under the laws of any such jurisdiction (except service of process with respect
to the offering and sale of the Offered Securities).

     (g) During the period of five years hereafter, the Company will furnish to
the Representatives and, upon request, to each of the other Underwriters, as
soon as practicable after the end of each fiscal year, a copy of its annual
report to stockholders for such year; and the Company will furnish to the
Representatives (i) as soon as available, a copy of each report and any
definitive proxy statement of the Company filed with the Commission under the
Securities Exchange Act of 1934 or mailed to stockholders, and (ii) from time to
time, such other information of a public nature concerning the Company as CS
First Boston may reasonably request.

     (h) The Company will pay all expenses incident to the performance of its
obligations under this Agreement and will reimburse the Underwriters (if and to
the extent incurred by them) for any filing fees and other expenses (including
fees and disbursements of counsel) incurred by them in connection with
qualification of the Offered Securities for sale under the laws of such
jurisdictions as CS First Boston designates and the printing of memoranda
relating thereto, for the filing fee of the National Association of Securities
Dealers, Inc. relating to the Offered Securities, for any travel expenses of the
Company's officers and employees and any other expenses of the Company in
connection with attending or hosting meetings with prospective purchasers of the
Offered Securities and for expenses incurred in distributing preliminary
prospectuses and the Prospectus (including any amendments and supplements
thereto) to the Underwriters.

     (i) For a period of 90 days after the date of the Prospectus, the Company
will not offer, sell, contract to sell, pledge or otherwise dispose of, directly
or indirectly, or file with the Commission a registration statement under the
Act relating to, any additional shares of its Securities or securities
convertible into or exchangeable or exercisable for any shares of its
Securities, or publicly disclose the intention to make any such offer, sale,
pledge, disposal or filing, without the prior written consent of CS First
Boston, except grants of employee stock options pursuant to the terms of a plan
in effect on the date hereof, issuances of Securities pursuant to the exercise
of such options or the exercise of any other employee stock options outstanding
on the date hereof.

     (j) For a period of 90 days after the date of the Prospectus, the Company
will cause each of its directors and executive officers to agree not to offer,
sell, contract to sell, pledge or otherwise dispose of, directly or indirectly,
any shares of the Securities without the prior written consent of CS First
Boston.

     6.  Conditions of the Obligations of the Underwriters.  The obligations of
the several Underwriters to purchase and pay for the Firm Securities on the
First Closing Date and the Optional Securities to be purchased on each Optional
Closing Date will be subject to the accuracy of the representations and
warranties on the part of the Company herein, to the accuracy of the statements
of Company officers made pursuant to the provisions hereof, to the performance
by the Company of its obligations hereunder and to the following additional
conditions precedent:

                                       9
<PAGE>
 
     (a) The Representatives shall have received a letter, dated the date of
delivery thereof (which, if the Effective Time of the Initial Registration
Statement is prior to the execution and delivery of this Agreement, shall be on
or prior to the date of this Agreement or, if the Effective Time of the Initial
Registration Statement is subsequent to the execution and delivery of this
Agreement, shall be prior to the filing of the amendment or post-effective
amendment to the registration statement to be filed shortly prior to such
Effective Time), of Deloitte & Touche LLP confirming that they are independent
public accountants within the meaning of the Act and the applicable published
Rules and Regulations thereunder and stating to the effect that:

     (i) in their opinion the financial statements and schedules examined by
them and included in the Registration Statements comply as to form in all
material respects with the applicable accounting requirements of the Act and the
related published Rules and Regulations;

     (ii) they have performed the procedures specified by the American Institute
of Certified Public Accountants for a review of interim financial information as
described in Statement of Auditing Standards No. 71, Interim Financial
Information, on the unaudited financial statements included in the Registration
Statements;

     (iii)  on the basis of the review referred to in Section 6(a)(ii), a
reading of the latest available interim financial statements of the Company,
inquiries of officials of the Company who have responsibility for financial and
accounting matters and other specified procedures, nothing came to their
attention that caused them to believe that:

     (A) the unaudited financial statements included in the Registration
Statements do not comply as to form in all material respects with the applicable
accounting requirements of the Act and the related published Rules and
Regulations or any material modifications should be made to such unaudited
financial statements for them to be in conformity with generally accepted
accounting principles;

     (B) at the date of the latest available balance sheet read by such
accountants, or at a subsequent specified date not more than three business days
prior to the date of this Agreement, there was any change in the capital stock
or any increase in short-term indebtedness or long-term debt of the Company and
its consolidated subsidiaries or, at the date of the latest available balance
sheet read by such accountants, there was any decrease in consolidated net
current assets or net assets, as compared with amounts shown on the latest
balance sheet included in the Prospectus; or

     (C) for the period from the closing date of the latest income statement
included in the Prospectus to the closing date of the latest available income
statement read by such accountants, or at the specified date referred to above
in Section 6(a)(iii)(B), there were any decreases, as compared with the
corresponding period of the previous year, in consolidated net sales, in net
operating income or in the total or per share amounts of consolidated net
income,

                                       10
<PAGE>
     except in all cases set forth in Sections 6(a)(iii)(B) and 6(a)(iii)(C) for
changes, increases or decreases that the Prospectus discloses have occurred
or may occur or which are described in such letter; and

     (iv) they have compared specified dollar amounts (or percentages derived
from such dollar amounts) and other financial information contained in the
Registration Statements (in each case to the extent that such dollar amounts,
percentages and other financial information are derived from the general
accounting records of the Company and its subsidiaries subject to the internal
controls of the Company's accounting system or are derived directly from such
records by analysis or computation) with the results obtained from inquiries, a
reading of such general accounting records and other procedures specified in
such letter and have found such dollar amounts, percentages and other financial
information to be in agreement with such results, except as otherwise specified
in such letter.

     For purposes of this Section 6(a), (i) if the Effective Time of the Initial
Registration Statement is subsequent to the execution and delivery of this
Agreement, "Registration Statements" shall mean the initial registration
statement as proposed to be amended by the amendment or post-effective amendment
to be filed shortly prior to its Effective Time, (ii) if the Effective Time of
the Initial Registration Statement is prior to the execution and delivery of
this Agreement but the Effective Time of the Additional Registration is
subsequent to such execution and delivery, "Registration Statements" shall mean
the Initial Registration Statement and the additional registration statement as
proposed to be filed or as proposed to be amended by the post-effective
amendment to be filed shortly prior to its Effective Time, and (iii)
"Prospectus" shall mean the prospectus included in the Registration Statements.
All financial statements and schedules included in material incorporated by
reference into the Prospectus shall be deemed included in the Registration
Statements for purposes of this Section 6(a).

     (b) If the Effective Time of the Initial Registration Statement is not
prior to the execution and delivery of this Agreement, such Effective Time shall
have occurred not later than 10:00 P.M., New York time, on the date of this
Agreement or such later date as shall have been consented to by CS First Boston.
If the Effective Time of the Additional Registration Statement (if any) is not
prior to the execution and delivery of this Agreement, such Effective Time shall
have occurred not later than 10:00 P.M., New York time, on the date of this
Agreement or, if earlier, the time the Prospectus is printed and distributed to
any Underwriter, or shall have occurred at such later date as shall have been
consented to by CS First Boston.  If the Effective Time of the Initial
Registration Statement is prior to the execution and delivery of this Agreement,
the Prospectus shall have been filed with the Commission in accordance with the
Rules and Regulations and Section 5(a) of this Agreement.  Prior to such Closing
Date, no stop order suspending the effectiveness of a Registration Statement
shall have been issued and no proceedings for that purpose shall have been
instituted or, to the knowledge of the Company or the Representatives, shall be
contemplated by the Commission.

     (c) Subsequent to the execution and delivery of this Agreement, there shall
not have occurred (i) any change, or any development or event involving a
prospective change, in the condition (financial or other), business, properties
or results of operations of the Company or its subsidiaries which, in the
judgment of a majority in interest of the Underwriters including the
Representatives, is material and adverse and makes it impractical or inadvisable
to proceed with completion of the public offering or the sale of and payment for
the Offered Securities; (ii) any 

                                       11
<PAGE>
 
downgrading in the rating of any debt securities of the Company by any
"nationally recognized statistical rating organization" (as defined for purposes
of Rule 436(g) under the Act), or any public announcement that any such
organization has under surveillance or review its rating of any debt securities
of the Company (other than an announcement with positive implications of a
possible upgrading, and no implication of a possible downgrading, of such
rating); (iii) any suspension or limitation of trading in securities generally
on The New York Stock Exchange, or any setting of minimum prices for trading on
such exchange, or any suspension of trading of any securities of the Company on
any exchange or in the over-the-counter market; (iv) any banking moratorium
declared by U.S. Federal or New York authorities; or (v) any outbreak or
escalation of major hostilities in which the United States is involved, any
declaration of war by Congress or any other substantial national or
international calamity or emergency if, in the judgment of a majority in
interest of the Underwriters including the Representatives, the effect of any
such outbreak, escalation, declaration, calamity or emergency makes it
impractical or inadvisable to proceed with completion of the public offering or
the sale of and payment for the Offered Securities.

     (d) The Representatives shall have received an opinion, dated such Closing
Date, of Ervin, Cohen & Jessup, counsel for the Company, to the effect that:

     (i) The Company has been duly incorporated and is an existing corporation
in good standing under the laws of the State of Delaware, with corporate power
and authority to own its properties and conduct its business as described in the
Prospectus; and the Company is duly qualified to do business as a foreign
corporation in good standing in all other jurisdictions in which its ownership
or lease of property or the conduct of its business requires such qualification
and in which the failure, individually or in the aggregate, to be so qualified
would have a material adverse effect on the Company;

     (ii) The Offered Securities delivered on such Closing Date and all other
outstanding shares of the Securities have been duly authorized and validly
issued, are fully paid and nonassessable and conform to the description thereof
contained in the Prospectus; and the stockholders of the Company have no
preemptive rights with respect to the Offered Securities;

     (iii)  There are no contracts, agreements or understandings known to such
counsel between the Company and any person granting such person the right to
require the Company to file a registration statement under the Act with respect
to any securities of the Company owned or to be owned by such person or to
require the Company to include such securities in the securities registered
pursuant to the Registration Statement or in any securities being registered
pursuant to any other registration statement filed by the Company under the Act
(other than the Company's obligation to register shares of the Securities
issuable under its employee benefit plans);

     (iv) No consent, approval, authorization or order of, or filing with, any
governmental agency or body or any court is required for the consummation of the
transactions contemplated by this Agreement in connection with the issuance or
sale of the Offered Securities by the Company, except such as have been obtained
and made and registration of the Offered Securities under the Act and such as
may be required under state securities laws;

                                       12
<PAGE>
 
     (v) The execution, delivery and performance of this Agreement and the
issuance and sale of the Offered Securities will not result in a breach or
violation of any of the terms and provisions of, or constitute a default under,
any statute, any rule, regulation (other than state securities laws) or order of
any governmental agency or body or any court having jurisdiction over the
Company or any subsidiary of the Company or any of their properties, or any
agreement or instrument known to such counsel to which the Company or any such
subsidiary is a party or by which the Company or any such subsidiary is bound or
to which any of the properties of the Company or any such subsidiary is subject,
or the charter or by-laws of the Company or any such subsidiary, which breach,
violation or default would, individually or in the aggregate, have a material
adverse effect on the Company and its subsidiaries, taken as a whole, and the
Company has full power and authority to authorize, issue and sell the Offered
Securities as contemplated by this Agreement;

     (vi) The Initial Registration Statement was declared effective under the
Act as of the date and time specified in such opinion, the Additional
Registration Statement (if any) was filed and became effective under the Act as
of the date and time (if determinable) specified in such opinion, the Prospectus
either was filed with the Commission pursuant to the subparagraph of Rule 424(b)
specified in such opinion on the date specified therein or was included in the
Initial Registration Statement or the Additional Registration Statement (as the
case may be), and, to the best of the knowledge of such counsel, no stop order
suspending the effectiveness of a Registration Statement or any part thereof has
been issued and no proceedings for that purpose have been instituted or are
pending or contemplated under the Act, and each Registration Statement and the
Prospectus, and each amendment or supplement thereto, as of their respective
effective or issue dates, complied as to form in all material respects with the
requirements of the Act and the Rules and Regulations; such counsel have no
reason to believe that any part of a Registration Statement or any amendment
thereto, as of its effective date or as of such Closing Date, contained any
untrue statement of a material fact or omitted to state any material fact
required to be stated therein or necessary to make the statements therein not
misleading or that the Prospectus or any amendment or supplement thereto, as of
its issue date or as of such Closing Date, contained any untrue statement of a
material fact or omitted to state any material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were
made, not misleading; the descriptions in the Registration Statements and the
Prospectus of statutes, legal and governmental proceedings and contracts and
other documents are accurate and fairly present the information required to be
shown; and such counsel do not know of any legal or governmental proceedings
required to be described in a Registration Statement or the Prospectus that are
not described as required or of any contracts or documents of a character
required to be described in a Registration Statement or the Prospectus or to be
filed as exhibits to a Registration Statement that are not described and filed
as required; it being understood that such counsel need express no opinion as to
the financial statements and schedules or other financial or statistical data
contained in the Registration Statement or the Prospectus;

     (vii)  This Agreement has been duly authorized, executed and delivered by
the Company;

                                       13
<PAGE>
 
     (viii)  The Asset Purchase and Lease Agreement, dated June 5, 1996 and as
amended July 15, 1996 (the "Purchase Agreement"), between Sanifill, Inc., a
Delaware corporation ("Sanifill"), Campbell Wells, Ltd., a Delaware limited
partnership ("Campbell Wells"), Now Disposal Holding Co., a Delaware
corporation, and the Company, and the NOW Disposal Agreement, dated June 4, 1996
(the "Disposal Agreement"), among Sanifill, Now Disposal Operating Co., a
Delaware corporation, and Campbell Wells have been duly authorized, executed and
delivered by the Company and Now Disposal Operating Co., respectively; and
 
     (ix) The execution, delivery and performance of the Purchase Agreement and
the Disposal Agreement and the consummation of the transactions contemplated
thereby have not and will not result in a breach or violation of any of the
terms and provisions of, or constitute a default under, any statute, any rule,
regulation or order of any governmental agency or body or any court having
jurisdiction over the Company or any subsidiary of the Company or any of their
properties, or any agreement or instrument known to such counsel to which the
Company or any such subsidiary is a party or by which the Company or any such
subsidiary is bound or to which any of the properties of the Company or any such
subsidiary is subject, or the charter or by-laws of the Company or any such
subsidiary, which breach, violation or default would, individually or in the
aggregate, have a material adverse effect on the Company and its subsidiaries,
taken as a whole.

     (e) The Representatives shall have received from Fulbright & Jaworski
L.L.P., counsel for the Underwriters, such opinion or opinions, dated such
Closing Date, with respect to the incorporation of the Company, the validity of
the Offered Securities delivered on such Closing Date, the Registration
Statements, the Prospectus and other related matters as the Representatives may
require, and the Company shall have furnished to such counsel such documents as
they request for the purpose of enabling them to pass upon such matters.

     (f) The Representatives shall have received a certificate, dated such
Closing Date, of the President or any Vice President and a principal financial
or accounting officer of the Company in which such officers, to the best of
their knowledge after reasonable investigation, shall state that: the
representations and warranties of the Company in this Agreement are true and
correct; the Company has complied with all agreements and satisfied all
conditions on its part to be performed or satisfied hereunder at or prior to
such Closing Date; no stop order suspending the effectiveness of any
Registration Statement has been issued and no proceedings for that purpose have
been instituted or are contemplated by the Commission; the Additional
Registration Statement (if any) satisfying the requirements of subparagraphs (1)
and (3) of Rule 462(b) was filed pursuant to Rule 462(b), including payment of
the applicable filing fee in accordance with Rule 111(a) or (b) under the Act,
prior to the time the Prospectus was printed and distributed to any Underwriter;
and, subsequent to the date of the most recent financial statements in the
Prospectus, there has been no material adverse change, nor any development or
event involving a prospective material adverse change, in the condition
(financial or other), business, properties or results of operations of the
Company and its subsidiaries taken as a whole except as set forth in or
contemplated by the Prospectus or as described in such certificate.

     (g) The Representatives shall have received a letter, dated such Closing
Date, of Deloitte & Touche LLP that meets the requirements of Section 6(a),
except that the specified date 

                                       14
<PAGE>
 
referred to in Section 6(a)will be a date not more than three business days
prior to such Closing Date for the purposes of this Section 6(g).

     (h) The Closing (as such term is defined in the Purchase Agreement) of the
transactions contemplated by the Purchase Agreement shall have been consummated
simultaneously with the purchase of the Firm Securities on the First Closing
Date.

The Company will furnish the Representatives with such conformed copies of such
opinions, certificates, letters and documents as the Representatives reasonably
request.  CS First Boston may in its sole discretion waive on behalf of the
Underwriters compliance with any conditions to the obligations of the
Underwriters hereunder, whether in respect of an Optional Closing Date or
otherwise.

     7.  Indemnification and Contribution.

     (a) The Company will indemnify and hold harmless each Underwriter against
any losses, claims, damages or liabilities, joint or several, to which such
Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement, the Prospectus, or any
amendment or supplement thereto, or any related preliminary prospectus, or arise
out of or are based upon the 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 will reimburse each Underwriter for any legal or
other expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such loss, claim, damage, liability or action as
such expenses are incurred; provided, however, that the Company will not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement in or omission or alleged omission from any of such documents in
reliance upon and in conformity with written information furnished to the
Company by any Underwriter through the Representatives specifically for use
therein, it being understood and agreed that the only information furnished by
any Underwriter consists of the information described as such in Section 7(b).

     (b) Each Underwriter will severally and not jointly indemnify and hold
harmless the Company against any losses, claims, damages or liabilities to which
the Company may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement, the Prospectus, or any
amendment or supplement thereto, or any related preliminary prospectus, or arise
out of or are based upon the omission or the alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company by such Underwriter through the Representatives
specifically for use therein, and will reimburse any legal or other expenses
reasonably incurred by the Company in connection with investigating or defending
any such loss, claim, damage, liability or action as such expenses are incurred,
it being understood and agreed that the only such information furnished by any
Underwriter consists of the following information in the Prospectus furnished on
behalf of each Underwriter: the last paragraph at the bottom of the cover page
concerning the terms of the offering by the Underwriters, the legend concerning
over-allotments, stabilizing and 

                                       15
<PAGE>
 
passive market making on the inside front cover page, the list of names and
number of shares of the Offered Securities to be purchased by each Underwriter
under the caption "Underwriting" and the statements in the fourth and the
seventh paragraphs under the caption "Underwriting".

     (c) Promptly after receipt by an indemnified party under this Section 7 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under
Section 7(a) or 7(b), notify the indemnifying party of the commencement thereof;
but the omission so to notify the indemnifying party will not relieve it from
any liability which it may have to any indemnified party otherwise than under
Section 7(a) or 7(b). In case any such action is brought against any indemnified
party and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein and, to the extent
that it may wish, jointly with any other indemnifying party similarly notified,
to assume the defense thereof, with counsel satisfactory to such indemnified
party (who shall not, except with the consent of the indemnified party, be
counsel to the indemnifying 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 under this
Section 7 for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened action in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party unless such settlement includes an unconditional release of such
indemnified party from all liability on any claims that are the subject matter
of such action.

     (d) If the indemnification provided for in this Section 7 is unavailable or
insufficient to hold harmless an indemnified party under Section 7(a) or 7(b),
then each indemnifying party shall contribute to the amount paid or payable by
such indemnified party as a result of the losses, claims, damages or liabilities
referred to in Section 7(a) or 7(b) (i) in such proportion as is appropriate to
reflect the relative benefits received by the Company on the one hand and the
Underwriters on the other from the offering of the Offered Securities or (ii) if
the allocation provided by clause (i) above is not permitted by applicable law,
in such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company on
the one hand and the Underwriters on the other in connection with the statements
or omissions which resulted in such losses, claims, damages or liabilities as
well as any other relevant equitable considerations. The relative benefits
received by the Company on the one hand and the Underwriters on the other shall
be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting expenses) received by the Company bear to the total
underwriting discounts and commissions received by the Underwriters. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or the Underwriters and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such untrue statement or
omission. The amount paid by an indemnified party as a result of the losses,
claims, damages or liabilities referred to in the first sentence of this Section
7(d), shall be deemed to include any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any
action or claim which is the subject of this Section 7(d). Notwithstanding the
provisions of this Section 7(d), no Underwriter shall be required to contribute
any amount in excess of the amount by which the total price at which the Offered
Securities underwritten by it and distributed to the public were offered 

                                       16
<PAGE>
 
to the public exceeds the amount of any damages which such Underwriter has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations in this Section 7(d) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

     (e) The obligations of the Company under this Section 7 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 7 shall be in addition to any liability that the
respective Underwriters may otherwise have and shall extend, upon the same terms
and conditions, to each director of the Company, to each officer of the Company
who has signed a Registration Statement and to each person, if any, who controls
the Company within the meaning of the Act.

     8.  Default of Underwriters.  If any Underwriter or Underwriters default in
their obligations to purchase the Offered Securities hereunder on either the
First or any Optional Closing Date and the aggregate number of shares of the
Offered Securities that such defaulting Underwriter or Underwriters agreed but
failed to purchase does not exceed 10% of the total number of shares of the
Offered Securities that the Underwriters are obligated to purchase on such
Closing Date, CS First Boston may make arrangements satisfactory to the Company
for the purchase of such Offered Securities by other persons, including any of
the Underwriters, but if no such arrangements are made by such Closing Date the
non-defaulting Underwriters shall be obligated severally, in proportion to their
respective commitments hereunder, to purchase the Offered Securities that such
defaulting Underwriters agreed but failed to purchase on such Closing Date.  If
any Underwriter or Underwriters so default and the aggregate number of shares of
the Offered Securities with respect to which such default or defaults occur
exceeds 10% of the total number of shares of the Offered Securities that the
Underwriters are obligated to purchase on such Closing Date and arrangements
satisfactory to CS First Boston and the Company for the purchase of such Offered
Securities by other persons are not made within 36 hours after such default,
this Agreement will terminate without liability on the part of any non-
defaulting Underwriter or the Company, except as provided in Section 9 (provided
that if such default occurs with respect to the Optional Securities after the
First Closing Date, this Agreement will not terminate as to the Firm Securities
or any Optional Securities purchased prior to such termination).  As used in
this Agreement, the term "Underwriter" includes any person substituted for an
Underwriter under this Section 8.  Nothing herein will relieve a defaulting
Underwriter from liability to the Company or any non-defaulting Underwriter for
its default.

     9. Survival of Certain Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the several Underwriters set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation, or statement as to the results thereof, made by or on behalf
of any Underwriter, the Company or any of their respective representatives,
officers or directors or any controlling person, and will survive delivery of
and payment for the Offered Securities. If this Agreement is terminated pursuant
to Section 8 or if for any reason the purchase of the Offered Securities by the
Underwriters is not consummated, the Company shall remain responsible for the
expenses to be paid or reimbursed by it pursuant to Section 5 and the respective
obligations of the Company and the Underwriters pursuant to Section 7 shall
remain in effect and if any Offered Securities have been purchased hereunder the
representations and warranties in Section 2 and all obligations under Section 5

                                       17
<PAGE>
 
shall also remain in effect. If the purchase of the Offered Securities by the
Underwriters is not consummated for any reason other than solely because of the
termination of this Agreement pursuant to Section 8 or the occurrence of any
event specified in clause (iii), (iv) or (v) of Section 6(c), the Company will
reimburse the Underwriters for all out-of-pocket expenses (including fees and
disbursements of counsel) reasonably incurred by them in connection with the
offering of the Offered Securities.

     10.  Notices.  All communications hereunder will be in writing and, if sent
to the Underwriters, will be mailed, delivered or telegraphed and confirmed to
the Representatives, c/o CS First Boston Corporation, Park Avenue Plaza, New
York, N.Y. 10055, Attention:  Investment Banking Department -- Transactions
Advisory Group, or, if sent to the Company, will be mailed, delivered or
telegraphed and confirmed to it at Newpark Resources, Inc., 3850 North Causeway,
Suite 1770, Metairie, Louisiana 70002, Attention: President; provided, however,
that any notice to an Underwriter pursuant to Section 7 will be mailed,
delivered or telegraphed and confirmed to such Underwriter.

     11.  Successors.  This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the officers
and directors and controlling persons referred to in Section 7, and no other
person will have any right or obligation hereunder.

     12.  Representation of Underwriters.  The Representatives will act for the
several Underwriters in connection with this financing, and any action under
this Agreement taken by the Representatives jointly or by CS First Boston will
be binding upon all the Underwriters.

     13.  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.

     14.  Applicable Law.  THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES
OF CONFLICTS OF LAWS.

     The Company hereby submits to the non-exclusive jurisdiction of the Federal
and state courts in the Borough of Manhattan in The City of New York in any suit
or proceeding arising out of or relating to this Agreement or the transactions
contemplated hereby.

     If the foregoing is in accordance with the Representatives' understanding
of our agreement, kindly sign and return to the Company one of the counterparts
hereof, whereupon it will become a binding agreement between the Company and the
several Underwriters in accordance with its terms.

                                        Very truly yours,

                                        NEWPARK RESOURCES, INC.

   RE: REGISTRATION STATEMENT ON FORM S-3

Gentlemen:

    We have acted as counsel to Newpark Resources, Inc., a Delaware corporation 
(the "Company"), in connection with the Company's Registration Statement on Form
S-3 (the "Registration Statement"), Registration No. 333-05805, as filed with 
the Securities and Exchange Commission under the Securities Act of 1933, as 
amended (the "Securities Act"). The Registration Statement covers the issuance 
by the Company of up to an aggregate of 3,450,000 shares of the Company's common

    In giving this opinion, we have reviewed the Company's Certificate of 
Incorporation, Bylaws and corporate proceeds, and such other documents as we 
have felt necessary or appropriate in order to render the opinions expressed 
herein. In such examination, we have assumed the genuineness of all signatures, 
the conformity with originals of all documents submitted to us as copies, the 
authenticity of the originals of such copies, the legal capacity of all natural 
persons and that the documents submitted to us for our review have not been and 
will not be altered, amended or repealed in any respect material to our opinions
as stated herein.

    Based upon the foregoing, we are of the opinion that the issuance of the 
Shares has been duly authorized by the Board of Directors of the Company and, 
when issued in accordance with the terms of the Registration Statement, 
including the exhibits thereto, the Shares will be legally issued, fully paid 
and non-assessable.

    We hereby consent to the use of this opinion as an exhibit to the 
Registration Statement and to the use of our name under the caption "Legal 
Matters" in the Prospectus filed as a part of the Registration Statement.


                                      Very truly yours,
