                            NEWPARK RESOURCES, INC.
              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Note 1    In the opinion of management the accompanying unaudited consolidated
          financial statements reflect all adjustments necessary to present
          fairly the financial position of Newpark Resources, Inc. ("Newpark"
          or the "Company") as of June 30, 1997, and the results of operations
          for the three and six month periods ended June 30, 1997 and 1996 and
          cash flows for the six month periods ended June 30, 1997 and 1996.
          All such adjustments are of a normal recurring nature. These interim
          financial statements should be read in conjunction with the December
          31, 1996 audited financial statements and related notes filed on Form
          10-K/A, Amendment No. 1 dated May 22, 1997.

Note 2    The consolidated financial statements include the accounts of Newpark
          and its wholly-owned subsidiaries. All material intercompany
          transactions are eliminated in consolidation.

Note 3    The results of operations for the six month period ended June 30,
          1997 are not necessarily indicative of the results to be expected for
          the entire year.

Note 4    Primary and fully diluted income per common share is calculated by
          dividing net income by the average shares of common stock of the
          Company ("Common Stock") and Common Stock equivalents outstanding
          during the period. When dilutive, stock options are included as share
          equivalents using the treasury stock method.

Note 6    Inventories at June 30, 1997 and December 31, 1996 consisted
          principally of raw materials.

Note 7    Interest of $184,000 and $167,000 was capitalized during the three
          months ended June 30, 1997 and 1996, respectively. For the six months
          ended June 30, 1997 and 1996, interest of $261,000 and $385,000 was
          capitalized, respectively.

Note 8    The Company maintains a $90.0 million bank credit facility in the
          form of a revolving line of credit commitment. The credit facility is
          secured by a pledge of substantially all of the Company's accounts
          receivable, inventory and property, plant and equipment. It bears
          interest at either a specified prime rate (8.50% at June 30, 1997) or
          the LIBOR rate (5.78% at June 30, 1997) plus a spread which is
          determined quarterly based upon the ratio of the Company's funded
          debt to cash flow. Interest on the line of credit is payable monthly
          on prime rate borrowings and the last day of the interest period on
          LIBOR rate borrowings. The line of credit matures on June 30, 2000.
          At June 30, 1997, $1.7 million of letters of credit were issued and
          outstanding, leaving a net of $88.3 million available for cash
          advances under the line of credit, against which $59.8 million had
          been borrowed. 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 June 30, 1997.

Note 9    During the six month period ended June 30, 1997, noncash
          transactions included the transfer of $1.1 million from fixed assets
          to a note receivable, representing the Company's investment in a
          joint manufacturing venture.

          Equipment purchases of $2,862,000 and $3,234,000 were included in
          accounts payable and accrued liabilities at June 30, 1997 and 1996,
          respectively, and in notes payable of $83,000 and $351,000 at June
          30, 1997 and 1996, respectively.

          Interest of $1,688,000 and $2,181,000 and income taxes of $2,889,000
          and $1,688,000 were paid during the six months ending June 30, 1997
          and 1996, respectively.

          During the six month period ended June 30, 1996, noncash transactions
          included the acquisition of certain patents in exchange for
          $5,841,000 of the Company's common stock and $1,200,000 in cash. In
          connection with the purchase of these patents the Company recorded a
          deferred tax liability of $900,000. Included in accounts receivable
          at June 30, 1996 are proceeds to be received from the sale of fixed
          assets of $893,000. Transfers from inventory to fixed assets of
          $1,521,000 were made during this period.

Note 10   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 $1,650,000 at June 30,
          1997. At June 30, 1997, the Company had outstanding guaranty
          obligations totaling $865,000 in connection with facility closure
          obligations.

          On August 29, 1996, the Company sold the land, buildings and certain
          equipment comprising substantially all of the assets of its former
          marine repair operation to the operator of the facility. These assets
          had previously been subject to an operating lease to the same party,
          and the purchase was made under the terms of a purchase option
          granted in the original lease. The Company has guaranteed certain of
          the debt obligations of the operator, limited to a maximum of $10
          million and reducing proportionately with debt repayments made by the
          operator.

          In conjunction with the acquisition of certain assets from Campbell
          Wells, Ltd. ("Campbell"), on August 12, 1996, the Company assumed the
          obligation to deliver to Campbell, for each of the next 25 years, for
          disposal at Campbell's landfarms the lesser of one-third of the
          barrels of NOW collected by Newpark from a defined market area or
          1,850,000 barrels of NOW, subject to certain adjustments. The initial
          price per barrel to be paid by Newpark to Campbell is $5.50 per
          barrel and is subject to adjustment in future years. Prior to any
          adjustments, Newpark's obligation is $10,175,000 annually. In
          addition, the liability of Newpark under the agreement is reduced by
          certain revenues earned by Campbell or its affiliates.

Note 11   In February 1997, the Financial Accounting Standards Board issued 
          Statement of Financial Accounting Standards Number 128 "Earnings per
          Share" ("SFAS 128") which changes the method of calculating earnings
          per share (EPS). SFAS 128 requires the presentation of "basic" EPS
          and "diluted" EPS on the face of the statement of income. Basic EPS
          is computed by dividing the net income available to





                                       8
<PAGE>   9

          common shareholders by the weighted average shares of outstanding
          common stock. The calculation of diluted EPS is similar to basic EPS
          except that the denominator includes dilutive common stock
          equivalents such as stock options and warrants. The statement is
          effective for financial statements issued for periods ending after
          December 15, 1997. At that time, the Company will be required to
          change the method currently used to compute EPS and to restate all
          prior periods. Early adoption is not permitted. This statement is not
          expected to have a significant impact on the Company's reported EPS
          amounts.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS


GENERAL

         During the six months ended June 30, 1997, the Company completed six
separate acquisition transactions. The first transaction involved SBM Drilling
Fluids Management, Inc. (SBM), a full-service drilling fluids company which
serves customers in the Louisiana and Texas Gulf Coast, which was accounted for
as a pooling of interests. Consideration for this transaction was the issuance
of 582,000 shares of Newpark Common Stock. The direct costs related to this
transaction, which are charged to current operations, amounted to $316,000. In
conjunction with the SBM acquisition, the Company instituted a liquid mud
recycling program, by which it plans to utilize a portion of the material
collected in its NOW waste operations as raw material for liquid mud sold by
the drilling fluids unit. The second transaction involved the acquisition of
approximately 120 acres of land from a major oil company. While the land has
marginal oil and gas production on it, the Company plans to develop the
property into an industrial waste disposal facility. The third transaction
involved the acquisition of an additional injection facility which included two
active injection wells located on 37 acres of land. The two land acquisitions
are adjacent to the Company's current Big Hill facility. The fourth transaction
involved the acquisition of a specialty milling company that grinds barite and
other industrial minerals at facilities in Houston, Texas and New Iberia,
Louisiana for oilfield and industrial markets. This acquisition provides a
supply of critical raw materials for the Company's drilling fluids operations.
This transaction involved the issuance of 166,667 shares of Newpark Common
Stock and was accounted for as a pooling of interests. The fifth transaction
involved the purchase of a retail drilling fluids company and wholesale
supplier of drilling fluids products. These companies provided added
distribution capacity for the Company's Gulf Coast drilling fluids market. This
transaction involved the issuance of 111,000 shares of Newpark Common Stock and
was accounted for as a purchase. The final transaction involved the acquisition
of an oilfield site contractor which expanded the Company's presence and
service capability in the site preparation and contracting business. This
transaction involved the issuance of 122,000 shares of Newpark Common Stock and
was accounted for as a purchase.

         Subsequent to June 30, 1997 the Company completed three additional
acquisitions. Two of these acquisitions added market and product coverage to
the Company's drilling fluids business, while the other expanded the Company's
presence in the site preparation and contracting business.

RESULTS OF OPERATIONS

         Results for the three months and six months ended June 30, 1996 have
been restated to give effect to the acquisition of SBM on a pooling of
interests basis. The following table represents revenue by product line, for
the three and six month periods ended June 30, 1997 and 1996. The product line
data has been reclassified from prior periods' presentation in order to more
effectively distinguish the fluids management services and mat rental services,
in which the Company maintains certain proprietary advantages, from its other
service offerings.

THREE MONTH PERIOD ENDED JUNE 30, 1997 COMPARED TO THREE MONTH PERIOD ENDED
JUNE 30, 1996

Revenues

         Total revenues increased to $48.0 million in the 1997 period from
$29.1 million in the 1996 period, an increase of $18.9 million or 65.0%,
consisting primarily of a $14.5 million increase in fluids management service
revenue and a $4.9 million increase in mat rental revenue. Principal components
of the increase in fluids management service revenue were NOW revenue, which
increased $7.5 million and drilling fluids sales and service revenue which
increased $8.8 million. These increases were partially offset by a $1.8 million
decrease in NORM revenue. The volume of NOW waste processed increased to 1.4
million barrels in 1997 compared to 675,000 barrels in 1996. This expanded
volume is attributable to the acquisition of a competitor's marine-related
collection operations in August 1996 and increases in the domestic market rig
count. The NOW volume increase accounts for approximately 84% of the revenue
change, with the remainder of the increase resulting from an increase in the
average disposal price in the 1997 quarter. The volume of NORM waste processed
was 8,200 barrels compared to 55,500 barrels in 1996. The volume decreased as
remediation operations in the Gulf Coast were hampered by unusually heavy
rainfall during the 1997 quarter. The increase in mat rental revenue reflects
improvements in the domestic market rig count and increased utilization of the
Company's mat inventory.

Operating Income

         Operating income of $14.0 million in the 1997 period increased by $7.0
million or 100.7% compared to $7.0 million in the 1996 period, representing an
improvement in operating margin to 29.1% in the 1997 period compared to 23.9%
in the 1996 period. The major components of the increase were increased
profitability from NOW disposal operations due to operating leverage and price
increases, and increased utilization and higher pricing of the Company's mat
inventory, increased profitability from drilling fluids sales, partially offset
by lower NORM revenue.

General and Administrative Expenses

         General and administrative expenses remained relatively unchanged
decreasing as a proportion of revenue to 1.6% from 2.5% in the 1996 period, and
increasing in absolute amount by $42,000.


Interest Expense

         Interest expense was $990,000 for the six months ended June 30, 1997
as compared to $1,008,000 in 1996.

Provision for Income Taxes

         For the 1997 and 1996 periods, the Company recorded income tax
provisions of $4.8 million and $2.0 million equal to 36.5% and 33.6% of pre-tax
income, respectively.


Statement of Financial Accounting Standards Number 128

         In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards Number 128 which changes the method
of calculating earnings per share. The statement is effective for financial
statements issued for periods ending after December 15, 1997. The Company will
adopt SFAS 128 in the fourth quarter of 1997, as early adoption is not
permitted. The adoption of this standard will not have a significant impact on
the Company's reported per share amounts.


SIX MONTH PERIOD ENDED JUNE 30, 1997 COMPARED TO SIX MONTH PERIOD ENDED JUNE
30, 1996

Revenues

         Total revenues increased to $90.9 million in the 1997 period from
$57.5 million in the 1996 period, an increase of $33.4 million or 58.1%,
consisting primarily of a $25.8 million increase in fluids management service
revenue and a $10.3 million increase in mat rental revenue, partially offset by
a $1.7 million decrease in integrated services revenue. Principal components of
the increase in fluids management service revenue were NOW revenue, which
increased $14.6 million and drilling fluids sales and service revenue which
increased $14.1 million. These increases were partially offset by a $2.9
million decrease in NORM revenue. The volume of NOW waste processed increased
to 2.8 million barrels in 1997 compared to 1.4 million barrels in 1996. This
expanded volume is attributable to the acquisition of a competitor's
marine-related collection operations in August 1996 and increases in the
domestic market rig count. The NOW volume increase accounts for approximately
82% of the revenue change, with the remainder of the increase resulting from an
increase in the average disposal price in the 1997 period. The volume of NORM
waste processed was 15,600 barrels compared to 92,700 barrels in 1996. The
volume decreased as remediation operations in the Gulf Coast were hampered by
unusually heavy rainfall during the 1997 period. The increase in mat rental
revenue reflects improvements in the domestic market rig count and increased
utilization of the Company's mat inventory. The decrease in integrated services
revenue was primarily due to the unusually low level of NOW remediation
activity as discussed above.

Operating Income

         Operating income of $25.9 million in the 1997 period increased by
$12.9 million or 98.5% compared to $13.1 million in the 1996 period,
representing an improvement in operating margin to 28.5% in the 1997 period
compared to 22.7% in the 1996 period. The major components of the increase were
increased profitability from the NOW disposal operations, increased utilization
and higher pricing of the Company's mat inventory, increased profitability from
drilling fluids sales, partially offset by lower NORM revenue.


General and Administrative Expenses

         General and administrative expenses remained relatively unchanged
decreasing as a proportion of revenue to 1.7% from 2.5% in the 1996 period, and
increasing in absolute amount by $133,000.


Interest Expense

         Interest expense was $1,845,000 for the six months ended June 30, 1997
as compared to $1,927,000 in 1996.


Provision for Income Taxes

         For the 1997 and 1996 periods, the Company recorded income tax
provisions of $8.8 million and $3.9 million equal to 36.3% and 34.9% of pre-tax
income, respectively.


LIQUIDITY AND CAPITAL RESOURCES

         The Company's working capital position (as restated to give effect to
the acquisition of SBM on a pooling of interests basis) increased by $15.7
million during the six months ended June 30, 1997. Key working capital data is
provided below:

          Working Capital (000's)                    $  45,604             $  29,881

</TABLE>

         To date during 1997, the Company's working capital needs have been met
primarily from operating cash flow and borrowings under the Company's credit
facility. Total cash generated from operations of $18.6 million was
supplemented by $17.9 million from financing activities to provide for cash of
$34.9 million used in investing activities.




                                      14

         During the quarter ended June 30, 1997, Newpark entered into a
restated credit agreement which provides it a $90 million secured revolving
line of credit. These borrowings bear interest at the option of the Company, at
either a specified prime rate or 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 June 30, 1997.

         The revolving line of credit matures June 30, 2000. At June 30, 1997,
$1.7 million of letters of credit were issued and outstanding under the line
and an additional $59.8 million had been borrowed and was outstanding
thereunder.

         Potential sources of additional funds, if required by the Company,
would include additional borrowings and the sale of equity securities. The
Company 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.

         Inflation has not materially impacted the Company's revenues or
income.

                                  (a) Terms of Revolving Commitment. On the
           terms and conditions hereinafter set forth, each Bank agrees
           severally to make Advances to Borrower and participate in Letters of
           Credit issued by the Agent on behalf of the Borrower from time to
           time during the period beginning on the Effective Date and ending on
           the Maturity Date in such amounts as Borrower may request up to an
           amount not to exceed, in the aggregate principal amount outstanding
           at any time, the Revolving Commitment. Subject to the terms hereof,
           the Borrower may borrow, repay and reborrow. The obligation of
           Borrower hereunder shall be evidenced by this Agreement and the Note
           or Notes issued in connection herewith, said Note or Notes to be as
           described in Section 3 hereof. Notwithstanding any other provision
           of this Agreement, no Advance shall be required to be made hereunder
           if any Default or Event of Default (as hereinafter defined) has
           occurred and is continuing. Each Advance under the Revolving
           Commitment shall be an amount of at least $500,000 or whole
           multiples of $100,000 in excess thereof. Irrespective of the face
           amount of the Note or Notes, the Banks shall never have the
           obligation to Advance any amount or amounts in excess of the
           Revolving Commitment or to increase the Revolving Commitment. The
           total number of Tranches under the Revolving Commitment which may be
           outstanding at any time hereunder shall never exceed four (4),
           whether such Tranches are Base Rate Loans, Eurodollar Loans, or a
           combination thereof.


                                     -14-
<PAGE>   21
                                  (b) Procedure for Borrowing. Whenever
           Borrower desires an Advance hereunder, it shall give Agent
           telegraphic, telex, facsimile or telephonic notice ("Notice of
           Borrowing") of such requested Advance, which in the case of
           telephonic notice, shall be promptly confirmed in writing. Each
           Notice of Borrowing shall be in the form of Exhibit "A" attached
           hereto and shall be received by Agent not later than 11:00 a.m.
           Lafayette, Louisiana time, (i) one Business Day prior to the date
           upon which any such Advance is requested to be funded (the
           "Borrowing Date") in the case of the Base Rate Loan, or (ii) three
           (3) Eurodollar Business Days prior to any proposed Borrowing Date in
           the case of Eurodollar Loans. Upon receipt of such Notice, Agent
           shall advise each Bank thereof; provided, that if the Banks have
           received at least one (1) Business Day's notice of such Advance
           prior to funding of a Base Rate Loan, or at least two (2) Eurodollar
           Business Days' notice of each Advance prior to funding in the case
           of a Eurodollar Loan, each Bank shall provide Agent at its office at
           200 W. Congress, Lafayette, Louisiana 70502, not later than 1:00
           p.m., Lafayette, Louisiana time, on the Borrowing Date, in
           immediately available funds, its Pro Rata Part of the requested
           Advance, but the aggregate of all such fundings by each Bank shall
           never exceed such Bank's Revolving Commitment. Not later than 2:00
           p.m., Lafayette, Louisiana time, on the Borrowing Date, Agent shall
           make available to Borrower at the same office, in like funds, the
           aggregate amount of such requested Advance. Neither Agent nor any
           Bank shall incur any liability to Borrower in acting upon any Notice
           of Borrowing referred to above which Agent or such Bank believes in
           good faith to have been given by a duly authorized officer or other
           person authorized to borrow on behalf of Borrower or for otherwise
           acting in good faith under this Section 2(b). Upon funding of
           Advances by Banks in accordance with this Agreement, pursuant to any
           such Notice of Borrowing, Borrower shall have effected Advances
           hereunder.

                                  (c) Letters of Credit. On the terms and
           conditions hereinafter set forth, the Agent shall from time to time
           during the period beginning on the Effective Date and ending on the
           Maturity Date upon request of Borrower issue standby and/or
           commercial Letters of Credit for the account of Borrower (the
           "Letters of Credit") in such face amounts as Borrower may request,
           but not to exceed in the aggregate face amount at any time
           outstanding the sum of Five Million Dollars ($5,000,000.00). The
           face amount of all Letters of Credit issued and outstanding
           hereunder shall be considered as non-interest bearing Advances on
           the Revolving Commitment and all payments made by the Agent on such
           Letters of Credit shall be considered as Advances under the Note.
           Each Letter of Credit issued for the account of Borrower hereunder
           shall (i) be in favor of such beneficiaries as specifically
           requested by Borrower, (ii) have an expiration date not exceeding
           the Maturity Date, and (iii) contain such other terms and provisions
           as


                                     -15-
<PAGE>   22
           may be required by Agent. Each Bank (other than Agent) agrees that,
           upon issuance of any Letter of Credit hereunder, it shall
           automatically acquire a participation in the Agent's liability under
           such Letter of Credit in an amount equal to such Bank's Revolving
           Commitment Percentage of such liability, and each Bank (other than
           Agent) thereby shall absolutely, unconditionally and irrevocably
           assumes, as primary obligor and not as surety, and shall be
           unconditionally obligated to Agent to pay and discharge when due,
           its Revolving Commitment Percentage of Agent's liability under such
           Letter of Credit. Borrower hereby unconditionally agrees to
           immediately pay and reimburse the Agent for the amount of each
           demand for payment under any Letter of Credit that is in substantial
           compliance with the provisions of any such Letter of Credit at or
           prior to the date on which payment is to be made by the Agent to the
           beneficiary thereunder, without presentment, demand, protest or
           other formalities of any kind. Upon receipt from any beneficiary of
           any Letter of Credit of any demand for payment under such Letter of
           Credit, the Agent shall promptly notify Borrower of the demand and
           the date upon which such payment is to be made by the Agent to such
           beneficiary in respect of such demand. Forthwith upon receipt of
           such notice from the Agent, Borrower shall advise the Agent whether
           or not it intends to borrow hereunder to finance its obligations to
           reimburse the Agent, and if so, submit a Notice of Borrowing as
           provided in Section 2(b) hereof. If Borrower fails to immediately
           pay and reimburse Agent as aforesaid, whether by borrowing hereunder
           or otherwise, Borrower hereby authorizes Agent to make an Advance
           hereunder as a Base Rate Loan in the amount of any payment made by
           Agent with respect to any Letters of Credit. The failure of the
           Borrower to pay such amounts in full to the Agent as required herein
           by the date specified by the Agent and the inability of the Agent to
           make an Advance as provided for in the foregoing sentence for any
           reason shall result in the Borrower being liable for interest on
           such amounts for the number of days that elapse from the day Agent
           honors such draft to the date on which such amounts are paid to the
           Agent by the Borrower at a rate per annum equal to the Default Rate.

                                  (d) Procedure for Obtaining Letters of
           Credit. The amount and date of issuance, renewal, extension or
           reissuance of a Letter of Credit pursuant to the Banks' commitment
           above in Section 2(c) shall be designated by Borrower's written
           request delivered to Agent at least three (3) Business Days prior to
           the date of such issuance, renewal, extension or reissuance.
           Concurrently with or promptly following the delivery of the request
           for a Letter of Credit, Borrower shall execute and deliver to the
           Agent an application and agreement with respect to the Letter of
           Credit, said application and agreement to be in the form used by the
           Agent. The Agent shall not be obligated to issue, renew, extend or
           reissue such Letters of Credit if (A) the conditions precedent
           specified in Section 10 hereof shall not have been satisfied, or (B)
           the amount thereon when added to the amount of the outstanding
           Letters of



                                     -16-
<PAGE>   23
           Credit exceeds Five Million Dollars ($5,000,000.00) or (C) the
           amount thereof when added to the Total Outstandings would exceed the
           Revolving Commitment. On the Effective Date, there are outstanding
           Letters of Credit in the total amount of $1,650,000. Once issued,
           the Agent shall have the authority (subject to the terms and
           conditions hereof) to renew and extend from time to time the expiry
           date of any Letter of Credit without the requirement of the joinder
           of any of the Banks, except that the Agent shall not renew or extend
           the expiry date of any such Letter of Credit beyond the Maturity
           Date. Borrower agrees to pay the Agent for the benefit of the Banks
           commissions for issuing the Letters of Credit (calculated separately
           for each Letter of Credit) in an amount equal to the greater of (i)
           seven-eighths of one percent (.875%) per annum (based upon the
           actual days elapsed in a year consisting of 365, or, if appropriate,
           366 days) on the maximum face amount of the Letter of Credit or (ii)
           $400.00. Borrower further agrees to pay Agent (i) an additional fee
           equal to one-eighth of one percent (.125%) per annum (based upon the
           actual days elapsed in a year consisting of 365, or, if appropriate,
           366 days) on the maximum face amount of each Letter of Credit, and
           (ii) an amendment fee for any amendment to letters of credit issued
           hereunder, said fee to be in the amount of $50.00 per amendment and
           shall be due upon the issuance of such amendment. Such commissions
           shall be payable prior to the issuance of each Letter of Credit and
           thereafter on each anniversary date of such issuance while such
           Letter of Credit is outstanding.

                                  (e) Voluntary Reduction of Revolving
           Commitment. Borrower may at any time, or from time to time, upon not
           less than three (3) Business Days prior written notice to Agent,
           reduce or terminate the Revolving Commitment; provided, however,
           that (i) each reduction in the Revolving Commitment must be in the
           amount of at least $1,000,000 or in increments of $1,000,000 and
           (ii) each reduction must be accompanied by a prepayment of the Notes
           in the amount by which the outstanding principal balance of the
           Notes exceed the Revolving Commitment as reduced pursuant to this
           Section 2(e). Any such reduction in the Revolving Commitment shall
           be permanent and not subject to reinstatement.

                                  (f) Several Obligations. The obligations of
           the Banks under the Revolving Commitment are several and not joint.
           The failure of any Bank to make an Advance required to be made by it
           shall not relieve any other Bank of its obligation to make its
           Advance, and no Bank shall be responsible for the failure of any
           other Bank to make the Advance to be made by such other Bank. No
           Bank shall be required to lend hereunder any amount in excess of its
           legal lending limit.

                    3. NOTES EVIDENCING LOANS. The loans described above in 
Section 2 shall be evidenced by notes of the Borrower as follows:


                                     -17-
<PAGE>   24
                                  (a) Form of Notes - The Revolving Loans shall
           be evidenced by Notes in the aggregate face amount of $90,000,000,
           in favor of each Bank in the amount of their Pro Rata Part and shall
           be in the form of Exhibit "B" hereto with appropriate insertions.
           Notwithstanding the face amount of the Notes, the actual principal
           amount due from Borrower to Banks on account of the Notes, as of any
           date of computation, shall be the sum of Advances then and
           theretofore made on account thereof, plus outstanding Reimbursement
           Obligations less all principal payments actually received by Banks
           in collected funds with respect thereto. Although the Notes may be
           dated as of the Effective Date, interest in respect thereof shall be
           payable only for the period during which the loans evidenced thereby
           are outstanding and, although the stated amount of the Notes may be
           higher, the Notes shall be enforceable, with respect to Borrower's
           obligation to pay the principal amount thereof, only to the extent
           of the unpaid principal amount of the loans.

                                  (b) Issuance of Additional Notes - At the
           Effective Date there shall be outstanding (i) three (3) Notes in the
           aggregate face amount of $90,000,000; one payable to Bank One in the
           face amount of $35,500,000, one payable to Deutsche in the face
           amount of $32,000,000 and one payable to Hibernia in the face amount
           of $22,500,000. From time to time new Notes may be issued to other
           Banks as such Banks become parties to this Agreement. Upon request
           from Agent, Borrower shall execute and deliver to Agent any such new
           or additional Notes. From time to time as new Notes are issued the
           Agent shall require each Bank to exchange its Notes for newly issued
           Notes to reflect the extent of each Bank's Revolving Commitments
           hereunder.

                                  (c) Interest Rates - The unpaid principal
           balance of the Notes shall bear interest from time to time as set
           forth in Section 4 hereof.

                                  (d) Payment of Interest - Interest on the
           Notes shall be payable on each Interest Payment Date

                                  (e) Payment of Principal - Principal of the
           Notes shall be due and payable to the Agent for the ratable benefit
           of the Banks on the Maturity Date unless earlier due in whole or in
           part as a result of an acceleration of the amount due or pursuant to
           the mandatory prepayment provisions of Section 8(b) hereof.



                                     -18-
<PAGE>   25
                                  (f) Payment to Banks - Each Bank's Pro Rata
           Part of payment or prepayment of the Notes shall be directed by wire
           transfer to such Bank by the Agent at the address provided to the
           Agent for such Bank for payments no later than 2:00 p.m., Lafayette,
           Louisiana, time on the Business Day such payments or prepayments are
           deemed hereunder to have been received by Agent; provided, however,
           in the event that any Bank shall have failed to make an Advance as
           contemplated under Section 2 hereof (a "Defaulting Bank") and the
           Agent or another Bank or Banks shall have made such Advance, payment
           received by Agent for the account of such Defaulting Bank or Banks
           shall not be distributed to such Defaulting Bank or Banks until such
           Advance or Advances shall have been repaid in full to the Bank or
           Banks who funded such Advance or Advances. Any payment or prepayment
           received by Agent at any time after 12:00 noon, Lafayette,
           Louisiana, time on a Business Day shall be deemed to have been
           received on the next Business Day. Interest shall cease to accrue on
           any principal as of the end of the day preceding the Business Day on
           which any such payment or prepayment is deemed hereunder to have
           been received by Agent. If Agent fails to transfer any principal
           amount to any Bank as provided above, then Agent shall promptly
           direct such principal amount by wire transfer to such Bank.

                                  (g) Sharing of Payments, Etc. - If any Bank
           shall obtain any payment (whether voluntary, involuntary, or
           otherwise) on account of the Revolving Loans or any Letter of
           Credit, (including, without limitation, any set-off) which is in
           excess of its Pro Rata Part of payments on the Revolving Loans or
           such Letter of Credit, such Bank shall purchase from the other Banks
           such participation as shall be necessary to cause such purchasing
           Bank to share the excess payment pro rata with each of them;
           provided that, if all or any portion of such excess payment is
           thereafter recovered from such purchasing Bank, the purchase shall
           be rescinded and the purchase price restored to the extent of the
           recovery. Borrower agrees that any Bank so purchasing a
           participation from another Bank pursuant to this Section may, to the
           fullest extent permitted by law, exercise all of its rights of
           payment (including the right of offset) with respect to such
           participation as fully as if such Bank were the direct creditor of
           Borrower in the amount of such participation.

                                  (h) Non-Receipt of Funds by the Agent -
           Unless the Agent shall have been notified by a Bank or Borrower (the
           "Payor") prior to the date on which such Bank is to make payment to
           the Agent of the proceeds of a Revolving Loan to be made by it
           hereunder or Borrower is to make a payment to the Agent for the
           account of one or more of the Banks, as the case may be (such
           payment being herein called the "Required Payment"), which notice
           shall be effective upon receipt, that the Payor does not intend to
           make the Required Payment to the



                                      -19-
<PAGE>   26
           Agent, the Agent may assume that the Required Payment has been made
           and may, in reliance upon such assumption (but shall not be required
           to), make the amount thereof available to the intended recipient on
           such date and, if the Payor has not in fact made the Required
           Payment to the Agent, the recipient of such payment shall, on
           demand, pay to the Agent the amount made available to it together
           with interest thereon in respect of the period commencing on the
           date such amount was made available by the Agent until the date the
           Agent recovers such amount at the rate applicable to such portion of
           the applicable Revolving Loan.

                                  (i) Capital Adequacy - If either (i) the
           introduction or implementation of or the compliance with or any
           change in or in the interpretation of any law, rule or regulation or
           (ii) the introduction or implementation of or the compliance with
           any mandatory request, directive or guideline from any central bank
           or other governmental authority (whether or not having the force of
           law) affects or would affect the amount of capital required or
           expected to be maintained by any Bank or any corporation controlling
           any Bank as a result of maintaining the Revolving Loans, then within
           fifteen (15) days after demand by such Bank, Borrower will pay to
           such Bank, from time to time as specified by such Bank, such
           additional amount or amounts which such Bank shall reasonably
           determine to be appropriate to compensate such Bank or any
           corporation controlling such Bank in light of such circumstances, to
           the extent that such Bank reasonably determines that the amount of
           any such capital would be increased, or the rate of return on any
           such capital would be reduced in whole or in part, based on the
           existence of the amount of the Revolving Loans or such Bank's
           Revolving Commitment under this Agreement.

                    4. INTEREST RATES.

                                  (a) Options

                           (i) Base Rate Loans. Borrower agrees to pay interest
                  on the Revolving Loans calculated utilizing a 360 day daily
                  interest factor over the number of days in an actual calendar
                  year (365, or if appropriate, 366 days) with respect to the
                  unpaid principal amount of each Base Rate Loan from the date
                  the proceeds thereof are made available to Borrower until
                  maturity (whether by acceleration or otherwise), at a varying
                  rate per annum equal to the lesser of (i) the Maximum Rate
                  (defined herein), or (ii) the sum of the Base Rate plus the
                  Base Rate Margin. Subject to the provisions of this Agreement
                  as to prepayment, the principal of the Notes representing
                  Base Rate Loans shall be payable as specified in Section 3(e)
                  hereof and the interest in respect of each Base Rate Loan
                  shall be payable on each Interest Payment Date. Past due
                  principal and, to the extent permitted by law, past due
                  interest in respect to each Base Rate Loan, shall bear
                  interest, payable on demand, at a rate per annum equal to the
                  Default Rate.

                           (ii) Eurodollar Loans. Borrower agrees to pay
                  interest calculated utilizing a 360 day daily interest factor
                  over the number of days in an actual calendar year (365, or
                  if appropriate, 366 days) with respect to the unpaid
                  principal amount of each Eurodollar Loan from the date the
                  proceeds thereof are made available to Borrower until
                  maturity (whether by acceleration or otherwise), at a varying
                  rate per annum equal to the lesser of (i) the Maximum Rate,
                  or (ii) the Eurodollar Rate plus the Eurodollar Margin.
                  Subject to the provisions of this Agreement with respect to
                  prepayment, the principal of the Notes shall be payable as
                  specified in Section 3(e) hereof and the interest with
                  respect to each Eurodollar Loan shall be payable on each
                  Interest Payment Date. Past due principal and, to the extent
                  permitted by law, past due interest shall bear interest,
                  payable on demand, at a rate per annum equal to the Default
                  Rate. Upon two (2) Eurodollar Business Days' written notice
                  prior to the making by the Banks of any Eurodollar Loan (in
                  the case of the initial Interest Period therefor) or the
                  expiration date of each succeeding Interest Period (in the
                  case of subsequent Interest Periods therefor), Borrower shall
                  have the option, subject to compliance by Borrower with all
                  of the provisions of this Agreement, as long as no Event of
                  Default exists, to specify whether the Interest Period
                  commencing on any


                                      12
<PAGE>   28
                  such date shall be a one (1), two (2) or three (3) month 
                  period. If Agent shall not have received timely notice of a 
                  designation of such Interest Period as herein provided, 
                  Borrower shall be deemed to have elected to convert all 
                  maturing Eurodollar Loans to Base Rate Loans.

                                  (b) Interest Rate Determination. The Agent
           shall determine each interest rate applicable to the Revolving Loans
           hereunder pursuant to the terms of this Agreement. The Agent shall
           give prompt notice to Borrower of each rate of interest so
           determined and its determination thereof shall be conclusive absent
           error.

                                  (c) Conversion Option. Borrower may elect
           from time to time (i) to convert all or any part of its Eurodollar
           Loans to Base Rate Loans by giving Agent irrevocable notice of such
           election in writing prior to 10:00 a.m. (Lafayette, Louisiana time)
           on the conversion date and such conversion shall be made on the
           requested conversion date, provided that any such conversion of
           Eurodollar Loan shall only be made on the last day of the Eurodollar
           Interest Period with respect thereof, (ii) to convert all or any
           part of its Base Rate Loans to Eurodollar Loans by giving the Agent
           irrevocable written notice of such election two (2) Eurodollar
           Business Days prior to the proposed conversion and such conversion
           shall be made on the requested conversion date or, if such requested
           conversion date is not a Eurodollar Business Day or a Business Day,
           as the case may be, on the next succeeding Eurodollar Business Day
           or Business Day, as the case may be. Any such conversion shall not
           be deemed to be a prepayment of any of the loans for purposes of
           this Agreement on the Notes.

                                  (d) Recoupment. If at any time the applicable
           rate of interest selected pursuant to Sections 4(a)(i) or 4(a)(ii)
           above shall exceed the Maximum Rate, thereby causing the interest on
           the Notes to be limited to the Maximum Rate, then any subsequent
           reduction in the interest rate so selected or subsequently selected
           shall not reduce the rate of interest on the Notes below the Maximum
           Rate until the total amount of interest accrued on the Note equals
           the amount of interest which would have accrued on the Notes if the
           rate or rates selected pursuant to Sections 4(a)(i) or (ii), as the
           case may be, had at all times been in effect.

                    5. SPECIAL PROVISIONS RELATING TO EURODOLLAR LOANS.

                                  (a) Unavailability of Funds or Inadequacy of
           Pricing. In the event that, in connection with any proposed
           Eurodollar Loan, any Bank (i) shall have determined that U.S. Dollar
           deposits of the relevant amount and for the relevant Eurodollar
           Interest Period for Eurodollar Loans are not available to such Bank
           in the London interbank market; or (ii) in good faith determines
           that the Eurodollar Interest Rate will not adequately reflect the
           cost to such Bank of maintaining or funding the Eurodollar Loans for
           such Interest Period, the obligations of the Banks to make the
           Eurodollar Loans, as the case may be, shall be suspended until such
           time such Bank in its sole discretion reasonably exercised
           determines that the event resulting in such suspension has ceased to
           exist. If any Bank shall make such determination it shall promptly
           notify the Agent in writing, Agent shall promptly notify Borrower in
           writing, and Borrower shall either repay the outstanding Eurodollar
           Loans owed to such Bank, without penalty, on the last day of the
           current Interest Period or convert the same to Base Rate Loans in
           the case of Eurodollar Loans on the last day of the then current
           Interest Period for such Eurodollar Loan.

                                  (b) Reserve Requirements. In the event of any
           change in any applicable law, treaty or regulation or in the
           interpretation or administration thereof, or in the event any
           central bank or other fiscal monetary or other authority having
           jurisdiction over any Bank or the loans contemplated by this
           Agreement shall impose, modify or deem applicable any reserve
           requirement of the Board of Governors of the Federal Reserve System
           on any Eurodollar Loan or loans, or any other reserve, special
           deposit, or similar requirements against assets to, deposits with or
           for the account of, or credit extended by, the Banks or shall impose
           on any Bank or the London interbank market, as the case may be, any
           other condition affecting this Agreement or the Eurodollar Loans and
           the result of any of the foregoing is to increase the cost to any
           Bank in making or maintaining its Eurodollar Loans or to reduce any
           amount (or the effective return on any amount) received by any Bank
           hereunder, then Borrower shall pay to the Banks upon demand of any
           Bank as additional interest on the Notes evidencing the Eurodollar
           Loans such additional amount or amounts as will reimburse the Banks
           for such additional cost or such reduction. The Banks shall give
           notice to Borrower upon becoming aware of any such change or
           imposition which may result in any such increase or reduction. A
           certificate of any Bank setting forth the basis for the
           determination of such amount necessary to compensate Banks as
           aforesaid shall be delivered to Borrower and shall be conclusive as
           to such determination and such amount, absent error.

<PAGE>   30
                                  (c) Taxes. Both principal and interest on the
           Notes evidencing the Eurodollar Loans and any other payment due
           pursuant to any Loan Document are payable without withholding or
           deduction for or on account of any taxes. If any taxes are levied or
           imposed on or with respect to the Notes evidencing the Eurodollar
           Loans or on any payment on the Notes evidencing the Eurodollar Loans
           made to any Bank, then, and in any such event, Borrower shall pay to
           the Banks upon demand of any Bank such additional amounts as may be
           necessary so that every net payment of principal and interest on the
           Notes evidencing the Eurodollar Loans, after withholding or
           deduction for or on account of any such taxes, will not be less than
           any amount provided for herein. In addition, if at any time when the
           Eurodollar Loans are outstanding any laws enacted or promulgated, or
           any court of law or governmental agency interprets or administers
           any law, which, in any such case, materially changes the basis of
           taxation of payments to any Bank of principal of or interest on the
           Notes evidencing the Eurodollar Loans by reason of subjecting such
           payments to double taxation or otherwise (except through an increase
           in the rate of tax on the overall net income of such Bank or Banks)
           then Borrower will pay the amount of loss to the extent that such
           loss is caused by such a change. The Banks shall give notice to
           Borrower upon becoming aware of the amount of any loss incurred by
           any Bank through enactment or promulgation of any such law which
           materially changes the basis of taxation of payments to one or more
           of the Banks. The Banks shall also give notice on becoming aware of
           any such enactment or promulgation which may result in such payments
           becoming subject to double taxation or otherwise. A certificate of
           any Bank setting forth the basis for the determination of such loss
           and the computation of such amounts shall be delivered to Borrower
           and shall be conclusive of such determination and such amount,
           absent error.

                                  (d) Change in Laws. If at any time any new
           law or any change in existing laws or in the interpretation of any
           new or existing laws shall make it unlawful for the Banks to
           maintain or fund its Eurodollar Loans hereunder, then the Banks
           shall promptly notify Borrower in writing and Borrower shall either
           repay the outstanding Eurodollar Loans owed to the Banks, without
           penalty, on the last day of the current Interest Periods (or, if any
           Bank may not lawfully continue to maintain and fund such Eurodollar
           Loans, immediately), or Borrower may convert such Eurodollar Loans
           at such appropriate time to Base Rate Loans.

                                  (e) Option to Fund. The Banks shall each have
           the option if Borrower elect a Eurodollar Loan, to purchase one or
           more deposits in order to fund or maintain its funding of the
           principal balance of its Note to which such Eurodollar Loan is
           applicable during the Interest Period in question; it being
           understood that the provisions of this Agreement relating to such
           funding are included only for the



                                     -24-
<PAGE>   31
           purpose of determining the rate of interest to be paid under such
           Eurodollar Loan and any amounts owing hereunder and under the Notes.
           Any Bank shall be entitled to fund and maintain its funding of all
           or any part of that portion of the principal balance of the Notes in
           any manner it sees fit, but all such determinations hereunder shall
           be made as if such Bank has actually funded and maintained that
           portion of the principal balance of the Notes to which a Eurodollar
           Loan is applicable during the applicable Interest Period through the
           purchase of deposits in an amount equal to the principal balance of
           the Notes to which such Eurodollar Loan is applicable and having a
           maturity corresponding to such Interest Period. Any Bank may fund
           the outstanding principal balance of the Notes which is to be
           subject to any Eurodollar Loan from any branch or office of such
           Bank as any Bank may designate from time to time.

                                  (f) Indemnity. Borrower shall indemnify and
           hold harmless the Banks against all reasonable and necessary
           out-of-pocket costs and expenses which the Banks may sustain (i) as
           a consequence of any Default or Event of Default by Borrower under
           this Agreement, or (ii) outside of their ordinary course of business
           in making and servicing any loan or loans as Eurodollar Loans under
           this Agreement.

                                  (g) Payments Not at End of Interest Period.
           If Borrower makes any payment of principal with respect to any
           Eurodollar Loan on any day other than the last day of the Interest
           Period applicable to such Eurodollar Loan or if Borrower fails to
           reborrow or convert after giving notice of its intent to do so, then
           Borrower shall reimburse the Banks on demand for any loss, cost or
           expense incurred by the Banks as a result of the timing of such
           payment or in redepositing such principal amount, including the sum
           of (i) the cost of funds to the Banks in respect of such principal
           amount so paid, for the remainder of the Interest Period applicable
           to such sum, reduced, if any Bank is able to redeposit such
           principal amount so paid for the balance of the Interest Period, by
           the interest earned by such Bank as a result of so redepositing such
           principal amount, plus (ii) any expense or penalty incurred by the
           Bank in redepositing such principal amount. A certificate of any
           Bank setting forth the basis for the determination of the amount
           owed by Borrower pursuant to this Section 5(g) shall be delivered to
           Borrower and shall be conclusive in the absence of manifest error.

                    6. COLLATERAL SECURITY. To secure the performance by 
Borrower and the Guarantors of their obligations hereunder, and under the Notes
and Security Instruments, whether now or hereafter incurred, matured or
unmatured, direct or contingent, joint or several, or joint and several,
including extensions, modifications, renewals and



                                     -25-
<PAGE>   32
increases thereof, and substitutions therefore, Borrower and the Guarantors
have either previously granted or assigned to Agent, or shall contemporaneously
with or prior to the execution of this Agreement and the Notes, grant and
assign to Agent for the ratable benefit of the Banks a first and prior Lien on
accounts, general intangibles, inventory and equipment located in the States of
Louisiana and Texas. The accounts, general intangibles, inventory and equipment
and other collateral in which Borrower and each Guarantor has heretofore or
herewith granted or hereafter grants to Agent for the ratable benefit of the
Banks a first and prior Lien (to the satisfaction of the Agent) in accordance
with this Section 6, as such properties and interests are from time to time
constituted, are hereinafter collectively called the "Collateral."

         The granting and assigning of such security interests and Liens by
Borrower and the Guarantors shall be pursuant to Security Instruments in form
and substance reasonably satisfactory to the Agent. Borrower and the Guarantors
will cause to be executed and delivered to the Agent, in the future, additional
Security Instruments if the Agent reasonably deems such are necessary to insure
perfection or maintenance of Banks' Liens in the Collateral or any part
thereof.

         In addition to the granting of the first and prior Liens referred to
above, Borrower and the Guarantors have either previously, or shall
contemporaneously herewith grant to the Banks a negative pledge on all of their
other assets.

                    7. FEES.

                                  (a) Unused Fee. Borrower shall pay to Agent
           for the ratable benefit of the Banks an unused commitment fee (the
           "Unused Commitment Fee") equivalent to the Unused Fee Rate
           (utilizing a 360-day daily interest factor over the number of days
           in an actual calendar year consisting of 365, or, if appropriate,
           366 days) on the daily average of the unadvanced portion of the
           Revolving Commitment less the outstanding amount of each unfunded
           Letter of Credit issued by the Agent pursuant to Section 2(c)
           hereof. The Unused Commitment Fee shall be payable in arrears on the
           last Business Day of each calendar quarter beginning September 30,
           1997 with the final fee payment due on the Maturity Date for any
           period then ending for which the Unused Commitment Fee shall not
           have been theretofore paid. In the event the Revolving Commitment
           terminates on any date prior to the end of any such monthly period,
           Borrower shall pay to the Agent for the ratable benefit of the
           Banks, on the date of such termination, the total Unused Commitment

           agreement or instrument to which Borrower or any Guarantor is a
           party in any respect that would be

           Board of Governors of the Federal Reserve System or to violate the

                  Banks with respect to or as a direct result of the presence,
                  escape, seepage, spillage, release, leaking, discharge or
                  migration from any properties owned or operated by the
                  Borrower or any Guarantor of any Hazardous Substance,
                  including without limitation, any claims asserted or arising
                  under any applicable environmental, health and safety laws,
                  codes and ordinances, and all rules and regulations
                  promulgated thereunder of all Governmental Authorities,
                  regardless of whether or not caused by or within the control
                  of the Borrower or any Guarantor.

                           (ii) It is the parties' understanding that the
                  Agent, the Co-Agent, the and the Banks do not now, have never
                  and do not intend in the future to exercise any operational
                  control or maintenance over the properties and operations
                  owned or operated by the Borrower or any Guarantor, nor have
                  they in the past, presently, or intend in the future to,
                  maintain an ownership interest in the properties owned or
                  operated by the Borrower or any Guarantor except as may arise
                  upon enforcement of the rights under the Security
                  Instruments.

                                  (o) Change of Principal Place of Business.
           Borrower and each Guarantor shall give Agent at least thirty (30)
           days prior written notice of its intention to move its principal
           place of business from the address set forth in Section 16 hereof.

                                  (p) Payables and Other Indebtedness. Borrower
           and each Guarantor shall pay their trade payables and other Debt
           that arise in the ordinary course of business promptly as they
           become due except to the extent any such trade payables or Debt are
           being contested in good faith.

                                  (q) Removal of Equipment and Other Inventory.
           In the event that the Borrower or any Guarantor removes any
           equipment and/or inventory (which removal is permitted if in the
           ordinary course of business) mortgaged to the Agent for the ratable
           benefit of the Banks, to a location other than a location in the
           States of Louisiana and Texas, details concerning such move shall be
           furnished to the Agent upon request. Borrower and each Guarantor


                                     -40-
<PAGE>   47
           agrees that it will not mortgage, pledge, sell, assign or grant a
           security interest on such moved equipment and/or inventory to any
           Person other than the Agent and the Banks.

                                  (r) Permits and Exclusivity Rights. The
           Borrower and each of the Guarantors shall provide the Banks upon
           request of the Agent, a listing (i) of all key permits required for
           business purposes and (ii) if applicable, all rights to exclusivity,
           particularly pertaining to mats.

                                  (s) Lock Box Agreements/Cash Control
           Accounts. As a condition precedent to the Banks' agreement to extend
           the Revolving Commitment, each of the Guarantors shall maintain a
           lock box for the collection of its respective accounts receivable,
           which lock boxes have been established by the Borrower, the
           Guarantors, and the Agent on behalf of the Banks. Further, the Agent
           has established through its Cash Management Department a cash
           control account (collectively, the "Control Accounts") for each of
           the Guarantors for the deposit by the Agent of all accounts
           receivable payments made to the lock boxes. The lock boxes and the
           Control Accounts are subject to (i) the terms and provisions of the
           letter agreements heretofore entered into by each of the Guarantors
           and the Agent, (collectively, the "Lock Box Agreements"), and (ii)
           the following terms and provisions:

                           (i) Access to the lock boxes shall be restricted to
                  the Agent until such time as the Notes and all other
                  obligations hereunder and under the other Loan Documents are
                  paid in full and the Notes cancelled.

                           (ii) In no event shall the Agent or any of the Banks
                  be liable for special or consequential damages to the
                  Borrower, the Guarantors or any third party related to or
                  arising from the performance or non-performance of lockbox
                  services or the breach thereof, or relating to equipment. In
                  addition, the Agent or any of the Banks shall not be liable
                  in damages for lost profits or for any claim or demand
                  asserted against the Agent or any of the Banks by any party.

                           (iii)    The  Borrower  and the  Guarantors  are not
                  entitled  to write  checks  on the Control Accounts.

                           (iv) On each Business Day the Agent will collect the
                  contents of each lock box and the same will be processed and
                  deposited by the Agent into the Control Accounts.


                                     -41-
<PAGE>   48
                           (v) The Agent, the Banks, the Borrower, and the
                  Guarantors agree that the Agent's duties and responsibilities
                  shall be limited to those set forth herein and in the Lock
                  Box Agreements and in performing services hereunder and
                  thereunder the Agent's legal duty to the Borrower and the
                  Guarantors is limited to the exercise of ordinary care.
                  Failure to exercise ordinary care shall not be inferable or
                  presumed by reason of the loss of an item or other
                  non-compliance with or non-performance of the terms hereof
                  without and in addition thereto, proof of the Agent's failure
                  to exercise such ordinary care as would legally constitute
                  negligence on the part of the Agent. Establishment of and
                  substantial compliance with the procedures attached to the
                  Lock Box Agreements shall be deemed conclusive proof of the
                  Agent's exercise of ordinary care in respect to the
                  transactions in which the loss (whether of money, items or
                  otherwise) or other non-performance or non-compliance with
                  the provisions of this Agreement occurred. In no event shall
                  the Agent be liable for loss or damages resulting from its
                  failure to perform duties pursuant to the provisions hereof
                  if such failure is due to the occurrence of any of the
                  following events: any act or omission taken or omitted by any
                  of the Guarantors or by the Borrower, electrical, mechanical
                  or other failure of computer or other equipment whether used,
                  operated or controlled by the Agent or others; strikes or
                  lockouts; delay or loss of items in the transmitting items to
                  or from the Agent; fire or other casualty; riot or civil
                  commotion; hurricanes, floods or other acts of nature; delay
                  in transportation, any government regulations or
                  interferences; or any event beyond the Agent's reasonable
                  control.

                           (vi) Upon the occurrence of an Event of Default, the
                  Agent shall be entitled to apply all collected balances in
                  the Control Accounts to the outstanding amount under the
                  Revolving Commitment as evidenced by the Notes on a Pro Rata
                  basis. So long as there is no Event of Default under the
                  Agreement, the Agent agrees to deposit all collected balances
                  in the Control Accounts to the said operating accounts.

                           (vii) The Guarantors are authorized to carry forward
                  on their books the uncollected balance in their respective
                  Control Accounts at the end of each month.

                           (viii) Each of the Guarantors agrees to immediately
                  deposit in its Control Account all accounts receivable
                  payments made directly to it.

                           (ix) The Guarantors do hereby grant to the Agent for
                  the pro rata benefit of the Banks a continuing security
                  interest in the lock boxes and the Control Accounts as
                  security for the indebtedness due under this Agreement and
                  the Notes.


                                     -42-
<PAGE>   49
                           (x) Upon the Borrower's payment in full of the Notes
                  and all obligations hereunder and the termination of the
                  Revolving Commitment, the Agent will terminate the Lock Box
                  Agreements.

                                  (t) New Guarantors. Borrower shall cause any
           new Subsidiary to execute and deliver to the Banks a guaranty in
           form and substance similar to the Guaranties, together with the same
           information provided by the other Guarantors pursuant to Section
           10(a)(iv) through (viii) hereof. If such new Subsidiary is located
           in, or doing business in, the States of Louisiana and/or Texas,
           Borrower shall cause such new Subsidiary to execute and delivery
           Security Instruments covering such new Subsidiary's accounts,
           general intangibles, equipment, inventory, and all proceeds
           therefrom, said Security Instruments to be in the form of the
           Security Instruments executed and delivered by the other Guarantors,
           together with a negative pledge covering all other assets of said
           new Subsidiary; provided, however, that notwithstanding any of the
           foregoing, if any new Subsidiary is acquired by Borrower for a cost
           of less than $10,000,000, such new Subsidiary shall have a period of
           six (6) months after the date of its acquisition to either (i) merge
           with an existing Guarantor, or (ii) execute and deliver the
           Guaranty, the information and the Security Instruments, if any,
           required by this Section 11(t).

                                  (u) Discharge Liens. Borrower and each
           Guarantor will discharge promptly any Lien, other than Permitted
           Liens, that may either arise by operation of law or otherwise
           without the active conduct of Borrower or any Guarantor.

                    12. NEGATIVE COVENANTS. The Borrower and each Guarantor 
covenants and agrees with the Banks, the Agent and the Co-Agent that, so long as
any Revolving Commitment, Revolving Loan, Letter of Credit, Reimbursement
Obligation or any fee, expense, or any other amount payable under any Loan
Document shall remain unpaid and outstanding:

                                  (a) Negative Pledge. Neither the Borrower
           nor any Guarantor shall without the prior written consent of the
           Banks:

                           (i)  create,  incur or assume any Lien, security  
                  interest or other  encumbrance on any of its assets 
                  or properties now owned or hereafter acquired, except 
                  Permitted Liens; or

                           (ii) sell, lease, transfer or otherwise dispose of,
                  in any fiscal year, any of its material assets or properties,
                  except for (A) sales, leases, transfers or other 



                                     -43-
<PAGE>   50
                  dispositions made in the ordinary course of its business, and 
                  (B) sales of assets not in excess of $5,000,000 in the 
                  aggregate in any fiscal year.

                                  (b) Current Ratio. Borrower will not allow
           the ratio of Consolidated Current Assets to Consolidated Current
           Liabilities to be less than 1.20 to 1.0 as of the end of any fiscal
           quarter.

                                  (c) Debt Service Coverage Ratio. Borrower
           will not allow the ratio of Consolidated Adjusted EBITDA to
           Consolidated Debt Service to be less than 1.50 to 1.0 as of the end
           of any fiscal quarter.

                                  (d) Maximum Total Debt Ratio. Borrower will
           not allow the ratio of total Debt (including Capitalized Lease
           Obligations) to Total Capitalization to ever exceed 50% as of the
           end of any fiscal quarter.

                                  (e) Tangible Net Worth. Borrower will not
           allow the Consolidated Tangible Net Worth to be less than
           $119,883,000 plus seventy-five percent (75%) of Borrower's
           Consolidated Net Income, if positive, for each fiscal quarter ending
           after December 31, 1996, tested at the end of each fiscal quarter.

                                  (f) Losses. The Borrower will not permit its
           Consolidated Net Income to be negative for any two consecutive
           fiscal quarters.

                                  (g) Consolidations and Mergers. Neither the
           Borrower nor any Guarantor shall consolidate or merge with or into
           any other Person, except that (i) the Borrower or any Guarantor may
           merge with another Person if Borrower or such Guarantor is the
           surviving entity in such merger; provided, however, that any such
           merger the cost of which exceeds $10,000,000 (which amount shall be
           calculated based upon either the cash price paid or the value, as of
           the date of the acquisition, of the stock or other assets used, as
           consideration for such merger or consolidation) shall require the
           prior consent of Majority Banks, which consent shall not be
           unreasonably withheld; and (ii) any Guarantor may merge with any
           other Guarantor, if, after giving effect to any such merger or
           consolidation, no Default or Event of Default shall have occurred
           and be continuing.

                                  (h) Debts, Guaranties and Other Obligations.
           Neither the Borrower nor any of the Guarantors will incur, create,
           assume or in any manner become or be liable in respect of any Debt,
           nor will



                                     -44-

           Borrower or any Guarantor guarantee or otherwise in any manner
           become or be liable in respect of any indebtedness, liabilities or
           other obligations of any other person or entity, whether by
           agreement to purchase the indebtedness of any other person or entity
           or agreement for the furnishing of funds to any other person or
           entity through the purchase or lease of goods, supplies or services
           (or by way of stock purchase, capital contribution, advance or loan)
           for the purpose of paying or discharging the indebtedness of any
           other person or entity, or otherwise, except that the foregoing
           restrictions shall not apply to:

                 or

                 Guarantor heretofore disclosed to Banks on Schedule "3"
                 hereto;

                           (iii) taxes, assessments or other government charges
                 which are not yet due or are being contested in good faith by
                 appropriate action promptly initiated and diligently
                 conducted, if such reserve as shall be required by GAAP shall
                 have been made therefor and levy and execution thereon have
                 been stayed and continue to be stayed; or

                           (iv) additional indebtedness for borrowed money or
                 letters of credit not in excess of $5,000,000.00 in the
                 aggregate during any fiscal year; or

                           (v) intercompany indebtedness between Borrower and
                 the Guarantors; or

                           (vi) indebtedness incurred in the ordinary course of
                 the Borrower's and the Guarantors' business; or

                 The Loma Company, L.L.C. ("Loma") dated April 1, 1997 pursuant
                 to which Bank One issued a letter of credit in the face amount

                 Loma, which Reimbursement Agreement, the Reimbursement Note
                 issued in connection therewith and the letter of credit are
                 secured by, among other things, a subordinate lien on all of
                 the assets of Borrower and the Guarantors which are also
                 Collateral for the Revolving Commitment; or

                           (viii) guaranties by Borrower of obligations of its

                 any or all of the foregoing.

                                  (i) Dividends. Borrower will not declare or
           pay any dividend (other than stock dividends), purchase, redeem or
           otherwise acquire for value any of its stock now or hereafter
           outstanding, return any capital to its stockholders, or make any

           result from the payment of such dividends.

                                  (j) Loans and Advances. Neither Borrower nor
           any Guarantor shall make or permit to remain outstanding any loans
           or advances to or in any person or entity, except that the foregoing
           restriction shall not apply to:

                           (i) loans or advances to any Person, the material
                 details of which have been set forth in the Financial
                 Statements of Borrower heretofore furnished to Banks on
                 Schedule "8" hereto; or

                           (ii) intercompany loans or advances between the
                 Borrower and the Guarantors; or

                           (iii) loans or advances to Loma not exceeding in the
                 aggregate at any time outstanding the amount of $3,000,000.

                                  (k) Sale or Discount of Receivables. Neither
           Borrower nor any Guarantor will discount or sell with recourse, or
           sell for less than the greater of the face or market value thereof,
           any of its accounts receivable.

                                  (l) Nature of Business. Neither Borrower nor
           any Guarantor will permit any material change to be made in the
           character of its business as carried on at the date hereof.

                                  (m) Transactions with Affiliates. Neither
           Borrower nor any Guarantor will enter into any transaction with any
           Affiliate, except transactions upon terms that are no less favorable
           to it than would be obtained in a transaction negotiated at arm's
           length with an unrelated third party.

                                  (n) Investments. Neither Borrower nor any
           Guarantor shall make any investment in any person or entity, except
           such restriction shall not apply to:

                           (i) investments existing at the Effective Date as
                 disclosed in the Financial Statements; and

                           (ii) investments consisting of Cash Equivalents; and

                           (iii) investments in new Subsidiaries up to an
                 amount of $10,000,000 (which amount shall be calculated based
                 upon either the cash price paid or the value, as of the date
                 of the acquisition, of the stock or other assets used, as
                 consideration for such investment) per new Subsidiary
                 (investments in excess of $10,000,000 shall require the prior
                 written consent of Majority Banks, which consent shall not be
                 unreasonably withheld).

                                  (o) Amendment to Articles of Incorporation or
           Partnership Agreements. Neither Borrower nor any corporate Guarantor
           will permit any material amendment to, or any material alteration
           of, its Articles of Incorporation. No limited partnership Guarantor
           will permit any material amendment to, or material alteration of,
           its partnership agreement. Borrower shall immediately notify Agent
           of any name change of Borrower or any Guarantor.

                                  (p) Stock of Guarantors. Borrower shall not
           sell, transfer or otherwise dispose of any of the voting stock of
           any of the Guarantors to any Person other than another Guarantor.

                    13. EVENTS OF DEFAULT. Any one or more of the following 
events shall be considered an "Event of Default" as that term is used herein:

                                  (a) Borrower shall fail to pay when due or
           declared due the principal of, and the interest on, the Notes, or
           any fee, reimbursement obligation or any other indebtedness of
           Borrower incurred pursuant to this Agreement or any other Loan
           Document; or

                                  (b) Any representation or warranty made under
           this Agreement, or in any certificate or statement furnished or made
           to the Banks pursuant hereto, or in connection herewith, or in
           connection with any document furnished hereunder, shall prove to be
           untrue in any material respect as of the date on which such
           representation or warranty is made (or deemed made), or any
           representation, statement (including financial statements),
           certificate, report or other data furnished or to be furnished or
           made under any Loan Document, including this Agreement, proves to
           have been untrue in any material respect, as of the date as of which
           the facts therein set forth were stated or certified; or

                                  (c) Default shall be made in the due
           observance or performance of any of the covenants or agreements
           contained in the Loan Documents, including this Agreement (excluding
           covenants contained in Section 12 of the Agreement for which there
           is no cure period), and such default shall continue for more than
           thirty (30) days; or

                                  (d) Default shall be made in the due
           observance or performance of the covenants contained in Section 12
           of this Agreement; or

                                  (e) Default by Borrower or any Guarantor
           shall be made in respect of any obligation for borrowed money, other
           than the Notes, for which Borrower or any Guarantor is liable
           (directly, by assumption, as guarantor or otherwise), or any
           obligations secured by any mortgage, pledge or other security
           interest, lien, charge or encumbrance with respect thereto, on any
           asset or property of Borrower or any Guarantor or in respect of any
           agreement relating to any such obligations unless neither Borrower
           nor any Guarantor is liable for same (i.e., unless remedies or
           recourse for failure to pay such obligations is limited to
           foreclosure of the collateral security therefor), and if such
           default shall continue beyond the applicable grace period, if any;
           or

                                  (f) Borrower or any Guarantor shall commence
           a voluntary case or other proceedings seeking liquidation,
           reorganization or other relief with respect to itself or its debts
           under any bankruptcy, insolvency or other similar law now or
           hereafter in effect or seeking an appointment of a trustee,
           receiver, liquidator, custodian or other similar official of 



                                     -48-
<PAGE>   55
          it or any substantial part of its property, or shall consent to any
          such relief or to the appointment of or taking possession by any such
          official in an involuntary case or other proceeding commenced against
          it, or shall make a general assignment for the benefit of creditors,
          or shall fail generally to pay its debts as they become due, or shall
          take any corporate action authorizing the foregoing; or

                                  (g) An involuntary case or other proceeding
           shall be commenced against Borrower or any Guarantor seeking
           liquidation, reorganization or other relief with respect to it or
           its debts under any bankruptcy, insolvency or similar law now or
           hereafter in effect or seeking the appointment of a trustee,
           receiver, liquidator, custodian or other similar official of it or
           any substantial part of its property, and such involuntary case or
           other proceeding shall remain undismissed and unstayed for a period
           of thirty (30) days; or an order for relief shall be entered against
           Borrower or any Guarantor under the federal bankruptcy laws as now
           or hereinafter in effect; or

                                  (h) A final judgment or order for the payment
           of money in excess of $1,000,000 (or judgments or orders aggregating
           in excess of $1,000,000 outstanding at any one time) shall be
           rendered against Borrower or any Guarantor and such judgments or
           orders shall continue unsatisfied and unstayed for a period of
           thirty (30) days unless such judgment or orders are fully covered by
           insurance or supersedeas bond; or

                                  (i) In the event the aggregate principal
           amount outstanding under the Notes shall at any time exceed the
           Revolving Commitment established for the Notes, and Borrower shall
           fail to comply with the provisions of Section 8(b) hereof; or

                                  (j) A Change of Control shall occur; or

                                  (k) Any Guarantor shall repudiate its
           Guaranty; or

                                  (l) In the event Borrower or any Guarantor
           fails to maintain a first priority perfected security interest on
           the Collateral in favor of the Banks.

           Upon occurrence of any Event of Default specified in Subsections
13(f) or (g) hereof, the entire principal amount due under the Notes and all
interest then accrued thereon, and any other liabilities of Borrower hereunder,
shall become immediately due and payable all without notice and without
presentment, demand, protest, notice of protest or dishonor or any other notice
of default of any kind, all of which are hereby expressly waived by Borrower.
In any other Event of Default, the Agent, upon request of Majority Banks, shall
by notice to Borrower declare the principal of, and all interest then accrued
on, the Notes and any other liabilities hereunder to be forthwith due and



                                     -49-
<PAGE>   56
payable, whereupon the same shall forthwith become due and payable without
presentment, demand, protest, notice of intent to accelerate, notice of
acceleration or other notice of any kind, all of which Borrower and each
Guarantor hereby expressly waive, anything contained herein or in the Notes to
the contrary notwithstanding. Nothing contained in this Section 13 shall be
construed to limit or amend in any way the Events of Default enumerated in the
Notes, or any other document executed in connection with the transaction
contemplated herein.

         Upon the occurrence and during the continuance of any Event of
Default, the Banks are hereby authorized at any time and from time to time,
without notice to Borrower or any Guarantor (any such notice being expressly
waived by Borrower and each Guarantor), to set-off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by any of the Banks to or for the
credit or the account of Borrower or any Guarantor against any and all of the
indebtedness of Borrower or any Guarantor under the Notes and the Loan
Documents, including this Agreement, irrespective of whether or not the Banks
shall have made any demand under the Loan Documents, including this Agreement
or the Notes and although such indebtedness may be unmatured. Any amount
set-off by any of the Banks shall be applied against the indebtedness owed the
Banks by Borrower and the Guarantors pursuant to this Agreement and the Notes.
The Banks agree promptly to notify Borrower and the Guarantors after any such
setoff and application, provided that the failure to give such notice shall not
affect the validity of such set-off and application. The rights of the Bank
under this Section are in addition to other rights and remedies (including,
without limitation, other rights of set-off) which the Banks may have.

                    14.THE AGENT AND THE BANKS.

                                  (a) Appointment and Authorization. Each Bank
           hereby appoints Agent as its agent, on its behalf: (i) to act as
           agent on behalf of such Bank in and under all Loan Documents; (ii)
           to arrange the means whereby the funds of Banks are to be made
           available to Borrower under the Loan Documents; (iii) to take such
           action as may be requested by any Bank under the Loan Documents
           (when such Bank is entitled to make such request under the Loan
           Documents); (iv) to receive all documents and items to be furnished
           to Banks under the Loan Documents; (v) to be the secured party,
           mortgagee, beneficiary, and similar party in respect of, and to
           receive, as the case may be, any collateral for the benefit of
           Banks; (vi) to promptly distribute to each Bank all material
           information, requests, documents and items received from Borrower
           under the Loan Documents; (vii) to promptly distribute to each Bank
           such Bank's Pro Rata Part of each payment or prepayment (whether
           voluntary, as proceeds of insurance thereon, or otherwise) in
           accordance with the terms of the Loan Documents and (viii) to
           deliver to the appropriate Persons requests, demands, approvals and
           consents received from Banks. Each Bank hereby authorizes Agent to
           take all actions and to exercise such powers under the Loan
           Documents as are specifically delegated to such Agent by the terms
           hereof or thereof, together with all other powers reasonably
           incidental thereto. With respect to its commitments hereunder and
           the Notes issued to it, Agent and any successor Agent shall have the
           same rights under the Loan Documents as any other Bank and may
           exercise the same as though it were not the Agent; and the term
           "Bank" or "Banks" shall, unless otherwise expressly indicated,
           include Agent and any successor Agent in its capacity as a Bank.
           Agent and any successor Agent and its Affiliates may accept deposits
           from, lend money to, act as trustee under indentures of and
           generally engage in any kind of business with Borrower, and any
           person which may do business with Borrower, all as if Agent and any
           successor Agent were not Agent hereunder and without any duty to
           account therefor to the Banks; provided that, if any payments in
           respect of any property (or the proceeds thereof) now or hereafter
           in the possession or control of Agent which may be or become
           security for the obligations of Borrower arising under the Loan
           Documents by reason of the general description of indebtedness
           secured or of property contained in any other agreements, documents
           or instruments related to any such other business shall be applied
           to reduction of the obligations of Borrower arising under the Loan
           Documents, then each Bank shall be entitled to share in such
           application according to its Pro Rata Part thereof. Each Bank, upon
           request of any other Bank, shall disclose to all other Banks all
           indebtedness and liabilities, direct and contingent, of Borrower to
           such Bank as of the time of such request and Borrower hereby
           irrevocably consents to any such disclosure.


                                     -51-


<PAGE>   58
                                  (b) Note Holders. From time to time as other
           Banks become a party to this Agreement, Agent shall obtain execution
           by Borrower of additional Notes in amounts representing the
           Revolving Commitment of each such new Bank, up to an aggregate face
           amount of all Notes not exceeding the Revolving Commitment. The
           obligation of such Bank shall be governed by the provisions of this
           Agreement, including but not limited to, the obligations specified
           in Section 2 hereof. From time to time, Agent may require that the
           Banks exchange their Notes for newly issued Notes to better reflect
           the Revolving Commitments of the Banks. Agent may treat the payee of
           any Note as the holder thereof until written notice of transfer has
           been filed with it, signed by such payee and in form satisfactory to
           Agent.

                                  (c) Consultation with Counsel. Banks agree
           that Agent may consult with legal counsel selected by Agent and
           shall not be liable for any action taken or suffered in good faith
           by it in accordance with the advice of such counsel.

                                  (d) Documents. Agent shall not be under a
           duty to examine or pass upon the validity, effectiveness,
           enforceability, genuineness or value of any of the Loan Documents or
           any other instrument or document furnished pursuant thereto or in
           connection therewith, and Agent shall be entitled to assume that the
           same are valid, effective, enforceable and genuine and what they
           purport to be.

                                  (e) Resignation or Removal of Agent. Subject
           to the appointment and acceptance of a successor Agent as provided
           below, Agent may resign at any time by giving written notice thereof
           to Banks and Borrower, and Agent may be removed at any time with or
           without cause by Majority Banks. If no successor Agent has been so
           appointed by Majority Banks (and approved by Borrower) and has
           accepted such appointment within 30 days after the retiring Agent's
           giving of notice of resignation or removal of the retiring Agent,
           then the retiring Agent may, on behalf of Banks, appoint a successor
           Agent. Any successor Agent must be approved by Borrower, which
           approval will not be unreasonably withheld. Upon the acceptance of
           any appointment as Agent hereunder by a successor Agent, such
           successor Agent shall thereupon succeed to and become vested with
           all the rights and duties of the retiring Agent, and the retiring
           Agent shall be discharged from its duties and obligations hereunder.
           After any retiring Agent's resignation or removal hereunder as
           Agent, the provisions of this Section 14 shall continue in effect
           for its benefit in respect to any actions taken or omitted to be
           taken by it while it was acting as Agent.



                                     -52-
<PAGE>   59
                                  (f) Responsibility of Agent. It is expressly
           understood and agreed that the obligations of Agent under the Loan
           Documents are only those expressly set forth in the Loan Documents
           and that Agent, as the case may be, shall be entitled to assume that
           no Default or Event of Default has occurred and is continuing,
           unless Agent, as the case may be, has actual knowledge of such fact
           or has received notice from a Bank or Borrower that such Bank or
           Borrower consider that a Default or an Event of Default has occurred
           and is continuing and specifying the nature thereof. Neither Agent
           nor any of their directors, officers, attorneys or employees shall
           be liable for any action taken or omitted to be taken by them under
           or in connection with the Loan Documents, except for its or their
           own gross negligence or willful misconduct. Agent shall incur no
           liability under or in respect of any of the Loan Documents by acting
           upon any notice, consent, certificate, warranty or other paper or
           instrument believed by it to be genuine or authentic or to be signed
           by the proper party or parties, or with respect to anything which it
           may do or refrain from doing in the reasonable exercise of its
           judgment, or which may seem to it to be necessary or desirable.

                 Agent shall not be responsible to Banks for
           any of Borrower's or any Guarantor's recitals, statements,
           representations or warranties contained in any of the Loan
           Documents, or in any certificate or other document referred to or
           provided for in, or received by any Bank under, the Loan Documents,
           or for the value, validity, effectiveness, genuineness,
           enforceability or sufficiency of or any of the Loan Documents or for
           any failure by Borrower or any Guarantor to perform any of their
           obligations hereunder or thereunder. Agent may employ agents and
           attorneys-in-fact and shall not be answerable, except as to money or
           securities received by it or its authorized agents, for the
           negligence or misconduct of any such agents or attorneys-in-fact
           selected by it with reasonable care.

                 The relationship between Agent and each Bank is only that of
           agent and principal and has no fiduciary aspects. Nothing in the
           Loan Documents or elsewhere shall be construed to impose on Agent
           any duties or responsibilities other than those for which express
           provision is therein made. In performing its duties and functions
           hereunder, Agent does not assume and shall not be deemed to have
           assumed, and hereby expressly disclaims, any obligation or
           responsibility toward or any relationship of agency or trust with or
           for Borrower or any of its beneficiaries or other creditors. As to
           any matters not expressly provided for by the Loan Documents, Agent
           shall not be required to exercise any discretion or take any action,
           but shall be required to act or to refrain from acting (and shall be
           fully protected in so acting or refraining from acting) upon the
           instructions of all Banks and such instructions shall be binding
           upon all Banks and all holders of the Notes; provided, however, that
           Agent shall not be required to take any action which is contrary to
           the Loan Documents or applicable law.

                                  (g) Independent Investigation. Each Bank
           severally represents and warrants to Agent that it has made its own
           independent investigation and assessment of the financial condition
           and affairs of Borrower in connection with the making and
           continuation of its participation hereunder and has not relied
           exclusively on any information provided to such Bank by Agent in
           connection herewith, and each Bank represents, warrants and
           undertakes to Agent that it shall continue to make its own
           independent appraisal of the credit worthiness of Borrower while the
           Notes are outstanding or its commitments hereunder are in force.
           Agent shall not be required to keep itself informed as to the
           performance or observance by Borrower of this Agreement or any other
           document referred to or provided for herein or to inspect the
           properties or books of Borrower. Other than as provided in this
           Agreement, Agent shall not have any duty, responsibility or
           liability to provide any Bank with any credit or other information
           concerning the affairs, financial condition or business of Borrower
           which may come into the possession of Agent.

                                  (h) Indemnification. Banks agree to indemnify
           Agent, ratably according to their respective Revolving Commitments
           on a Pro Rata basis, from and against any and all liabilities,
           obligations, losses, damages, penalties, actions, judgments, suits,
           costs, expenses or disbursements of any proper and reasonable kind
           or nature whatsoever which may be imposed on, incurred by or
           asserted against Agent in any way relating to or arising out of the
           Loan Documents or any action taken or omitted by Agent under the
           Loan Documents, provided that no Bank shall be liable for any
           portion of such liabilities, obligations, losses, damages,
           penalties, actions, judgments, suits, costs, expenses or
           disbursements resulting from Agent's gross negligence or willful
           misconduct. Each Bank shall be entitled to be reimbursed by the
           Agent for any amount such Bank paid to Agent under this Section
           14(h) to the extent the Agent has been reimbursed for such payments
           by Borrower or any other Person. THE PARTIES INTEND FOR THE
           PROVISIONS OF THIS SECTION TO APPLY TO AND PROTECT THE AGENT FROM
           THE CONSEQUENCES OF ANY LIABILITY INCLUDING STRICT LIABILITY IMPOSED
           OR THREATENED TO BE IMPOSED ON AGENT AS WELL AS FROM THE
           CONSEQUENCES OF ITS OWN NEGLIGENCE, WHETHER OR NOT THAT NEGLIGENCE
           IS THE SOLE, CONTRIBUTING OR CONCURRING CAUSE OF ANY SUCH LIABILITY.

                                  (i) Benefit of Section 14. The agreements
           contained in this Section 14 are solely for the benefit of Agent and
           the Banks and are not for the benefit of, or to be relied upon by,
           Borrower, any affiliate of Borrower or any other person.

                                  (j) Pro Rata Treatment. Subject to the
           provisions of this Agreement, each payment (including each
           prepayment) by Borrower or any Guarantor and collection by Banks
           (including offsets) on account of the principal of and interest on
           the Notes and fees provided for in this Agreement, shall be made Pro
           Rata; provided, however, in the event that any Defaulting Bank shall
           have failed to make an Advance as contemplated under Section 3
           hereof and Agent or another Bank or Banks shall have made such
           Advance, payment received by Agent for the account of such
           Defaulting Bank or Banks shall not be distributed to such Defaulting
           Bank or Banks until such Advance or Advances shall have been repaid
           in full to the Bank or Banks who funded such Advance or Advances.

                                  (k) Assumption as to Payments. Except as
           specifically provided herein, unless Agent shall have received
           notice from Borrower prior to the date on which any payment is due
           to Banks hereunder that Borrower will not make such payment in full,
           Agent may, but shall not be required to, assume that Borrower has
           made such payment in full to Agent on such date and Agent may, in
           reliance upon such assumption, cause to be distributed to each Bank
           on such due date an amount equal to the amount then due such Bank.
           If and to the extent Borrower shall not have so made such payment in
           full to Agent, each Bank shall repay to Agent forthwith on demand
           such amount distributed to such Bank together with interest thereon,
           for each day from the date such amount is distributed to such Bank
           until the date such Bank repays such amount to Agent, at the
           interest rate applicable to such portion of the Revolving Loans.

                                  (l) Other Financings. Without limiting the
           rights to which any Bank otherwise is or may become entitled, such
           Bank shall have no interest, by virtue of this Agreement or the Loan
           Documents, in (a) any present or future loans from, letters of
           credit issued by, or leasing or other financial transactions by, any
           other Bank to, on behalf of, or with Borrower or any Guarantor
           (collectively referred to herein as "Other Financings") other than
           the obligations hereunder; (b) any present or future guarantees by
           or for the account of Borrower or any Guarantor which are not
           contemplated by the Loan Documents; (c) any present or future
           property taken as security for any such Other Financings; or (d) any
           property now or hereafter in the possession or control of any other
           Bank which may be or become security for the obligations of Borrower
           or any Guarantor arising under any loan document by reason of the
           general description of indebtedness secured or property contained in
           any other agreements, documents or instruments relating to any such
           Other Financings.

                                  (m) Interests of Banks. Nothing in this
           Agreement shall be construed to create a partnership or joint
           venture between Banks 


                                     -55-

<PAGE>   62
           for any purpose. Agent, Banks and Borrower recognize that the
           respective obligations of Banks under the Revolving Commitments
           shall be several and not joint and that neither Agent, nor any of
           Banks shall be responsible or liable to perform any of the
           obligations of the other under this Agreement. Each Bank is deemed
           to be the owner of an undivided interest in and to all rights,
           titles, benefits and interests belonging and accruing to Agent
           under the Security Instruments, including, without limitation,
           liens and security interests in any collateral, fees and payments
           of principal and interest by Borrower under the Revolving
           Commitments on a Pro Rata basis. Each Bank shall perform all duties
           and obligations of Banks under this Agreement in the same
           proportion as its ownership interest in the Loans outstanding at
           the date of determination thereof.
           
                                  (n) Investments. Whenever Agent in good faith
           determines that it is uncertain about how to distribute to Banks any
           funds which it has received, or whenever Agent in good faith
           determines that there is any dispute among the Banks about how such
           funds should be distributed, Agent may choose to defer distribution
           of the funds which are the subject of such uncertainty or dispute.
           If Agent in good faith believes that the uncertainty or dispute will
           not be promptly resolved, or if Agent is otherwise required to
           invest funds pending distribution to the Banks, Agent may invest
           such funds pending distribution (at the risk of Borrower). All
           interest on any such investment shall be distributed upon the
           distribution of such investment and in the same proportions and to
           the same Persons as such investment. All monies received by Agent
           for distribution to the Banks (other than to the Person who is Agent
           in its separate capacity as a Bank) shall be held by the Agent
           pending such distribution solely as Agent for such Banks, and Agent
           shall have no equitable title to any portion thereof.

                                  (o) Withholding Tax. Each Bank agrees to
           furnish (if it is organized under the laws of any jurisdiction other
           than the United States or any State thereof) to the Agent and the
           Borrower prior to the time that the Borrower is required to make any
           payment of principal, interest or fees hereunder, to such Bank,
           duplicate executed originals of either U.S. Internal Revenue Service
           Form 4224 or U.S. Internal Revenue Service Form 1001 (wherein such
           Bank claims entitlement to the benefits of a tax treaty that
           provides for a complete exemption from U.S. federal income
           withholding tax on all payments hereunder) and agrees to provide new
           Forms 4224 of 1001 upon the expiration of any previously delivered
           from or comparable statements in accordance with applicable U.S. law
           and regulations and amendments thereto, and agrees to comply with
           all applicable U.S. laws and regulations with regard to such
           withholding tax exemption.

                    15. EXERCISE OF RIGHTS. No failure to exercise, and no 
delay in exercising, on the part of the Agent or the Banks, any right



                                     -56-
<PAGE>   63
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise thereof preclude any other or further exercise thereof or the exercise
of any other right. The rights of the Agent and the Banks hereunder shall be in
addition to all other rights provided by law. No modification or waiver of any
provision of the Loan Documents, including this Agreement, or the Notes, nor
consent to departure therefrom, shall be effective unless in writing, and no
such consent or waiver shall extend beyond the particular case and purpose
involved. No notice or demand given in any case shall constitute a waiver of
the right to take other action in the same, similar or other circumstances
without such notice or demand.

                    16. NOTICES. Any notices or other communications
required or permitted to be given by this Agreement or any other documents and
instruments referred to herein must be given in writing either by facsimile
transmission or personally delivered or couriered or mailed by prepaid
certified or registered mail to the party to whom such notice or communication

purposes of this Agreement by giving notice of such change to the other party
pursuant to this Section 16.

                    17. EXPENSES. Borrower shall pay (i) all reasonable and 
necessary out-of-pocket expenses of the Banks, including reasonable fees and
disbursements of special counsel for the Agent, in connection with the
preparation of this Agreement, the other Loan Documents, title and other due
diligence and closing of the transaction described in this Agreement, any waiver
or consent hereunder or any amendment hereof or any default or Event of Default
or alleged default or Event of Default hereunder, (ii) all reasonable and
necessary out-of-pocket expenses of the Agent, including reasonable fees and
disbursements of special counsel for the Agent in connection with the
preparation of any participation agreement for a participant or participants
requested by Borrower or any amendment thereof and (iii) if a default or an
Event of Default occurs, all reasonable and necessary out-of-pocket expenses
incurred by the Banks, including fees and disbursements of counsel, in
connection with such default and Event of Default and collection and other
enforcement proceedings resulting therefrom. Borrower shall indemnify the Banks
against any transfer taxes, document taxes, assessments or charges made by any
governmental authority by reason of the execution, delivery and filing of the
Loan Documents.


                                     -57-
<PAGE>   64
                    18. INDEMNITY. Borrower agrees to indemnify and hold 
harmless the Banks and their respective officers, employees, agents, attorneys
and representatives (singularly, an "Indemnified Party", and collectively, the
"Indemnified Parties") from and against any loss, cost, liability, damage or
expense (including the reasonable fees and out-of-pocket expenses of counsel to
the Banks, including all local counsel hired by such counsel) ("Claim") incurred
by the Banks in investigating or preparing for, defending against, or providing
evidence, producing documents or taking any other action in respect of any
commenced or threatened litigation, administrative proceeding or investigation
under any federal securities law, federal or state environmental law, or any
other statute of any jurisdiction, or any regulation, or at common law or
otherwise, which is alleged to arise out of or is based upon any acts, practices
or omissions or alleged acts, practices or omissions of Borrower or its agents
or arises in connection with the duties, obligations or performance of the
Indemnified Parties in negotiating, preparing, executing, accepting, keeping,
completing, countersigning, issuing, selling, delivering, releasing, assigning,
handling, certifying, processing or receiving or taking any other action with
respect to the Loan Documents and all documents, items and materials
contemplated thereby even if any of the foregoing arises out of an Indemnified
Party's ordinary negligence. The indemnity set forth herein shall be in addition
to any other obligations or liabilities of Borrower to the Banks hereunder or at
common law or otherwise, and shall survive any termination of this Agreement,
the expiration of the Revolving Loans and the payment of all indebtedness of
Borrower to the Banks hereunder and under the Notes, provided that Borrower
shall have no obligation under this Section to the Bank with respect to any of
the foregoing arising out of the gross negligence or willful misconduct of any
Indemnified Party. If any Claim is asserted against any Indemnified Party, the
Indemnified Party shall endeavor to notify Borrower of such Claim (but failure
to do so shall not affect the indemnification herein made except to the extent
of the actual harm caused by such failure). The Indemnified Party shall have the
right to employ, at Borrower's expense, counsel of the Indemnified Parties'
choosing and to control the defense of the Claim. Borrower may at its own
expense also participate in the defense of any Claim. Each Indemnified Party may
employ separate counsel in connection with any Claim to the extent such
Indemnified Party believes it reasonably prudent to protect such Indemnified
Party. THE PARTIES INTEND FOR THE PROVISIONS OF THIS SECTION TO APPLY TO AND
PROTECT EACH INDEMNIFIED PARTY FROM THE CONSEQUENCES OF ANY LIABILITY INCLUDING
STRICT LIABILITY IMPOSED OR THREATENED TO BE IMPOSED ON AGENT AS WELL AS FROM
THE CONSEQUENCES OF ITS OWN NEGLIGENCE, WHETHER OR NOT THAT NEGLIGENCE IS THE
SOLE, CONTRIBUTING, OR CONCURRING CAUSE OF ANY CLAIM.

<PAGE>   65
                    19. GOVERNING LAW. THE INTERNAL LAWS OF THE STATE OF 
LOUISIANA AND THE UNITED STATES OF AMERICA SHALL GOVERN THE RIGHTS AND DUTIES OF
THE PARTIES HERETO AND THE VALIDITY, CONSTRUCTION, ENFORCEMENT, AND
INTERPRETATION OF THIS AGREEMENT, THE NOTES AND THE GUARANTIES AND OTHER LOAN
DOCUMENTS.

                    20. INVALID PROVISIONS. If any provision of this Agreement 
is held to be illegal, invalid, or unenforceable under present or future laws
effective during the term of this Agreement, such provisions shall be fully
severable and this Agreement shall be construed and enforced as if such illegal,
invalid or unenforceable provision had never comprised a part of this Agreement,
and the remaining provisions of the Agreement shall remain in full force and
effect and shall not be affected by the illegal, invalid or unenforceable
provision or by its severance from this Agreement.

                    21. MAXIMUM INTEREST RATE.  Regardless of any provisions 
contained in this Agreement or in any other documents and instruments referred
to herein, the Banks shall never be deemed to have contracted for or be entitled
to receive, collect or apply as interest on the Notes any amount in excess of
the Maximum Rate, and in the event any Bank ever receives, collects or applies
as interest any such excess, or if an acceleration of the maturities of any
Notes or if any prepayment by Borrower result in Borrower having paid any
interest in excess of the Maximum Rate, such amount which would be excessive
interest shall be applied to the reduction of the unpaid principal balance of
the Notes for which such excess was received, collected or applied, and, if the
principal balance of such Note is paid in full, any remaining excess shall
forthwith be paid to Borrower. All sums paid or agreed to be paid to the Banks
for the use, forbearance or detention of the indebtedness evidenced by the Notes
and/or this Agreement shall, to the extent permitted by applicable law, be
amortized, prorated, allocated and spread throughout the full term of such
indebtedness until payment in full so that the rate or amount of interest on
account of such indebtedness does not exceed the Maximum Rate. In determining
whether or not the interest paid or payable under any specific contingency
exceeds the Maximum Rate of interest permitted by law, Borrower and the Banks
shall, to the maximum extent permitted under applicable law, (i) characterize
any non-principal payment as an expense, fee or premium, rather than as
interest; and (ii) exclude voluntary prepayments and the effect thereof; and
(iii) compare the total amount of interest contracted for, charged or received
with the total amount of interest which could be contracted for, charged or
received throughout the entire contemplated term of the Notes at the Maximum
Rate.

                    22. AMENDMENTS OR WAIVERS. Neither this Agreement nor any 
other Loan Document nor any terms hereof or thereof



                                     -59-
<PAGE>   66
may be changed, waived or discharged or terminated unless such change,
waiver, discharge or termination is in writing signed by the Borrower and the
Majority Banks, provided that no such change, waiver, discharge or termination
shall, without the consent of each Bank (other than a Defaulting Bank) affected
thereby, (i) extend the Maturity Date (it being understood that any waiver of
the application of any prepayment of the Revolving Loans or the method of
application of any prepayment shall not constitute any such extension), to
reduce the rate or extend the time of payment of interest (other than as a
result of waiving the applicability of any post-default increase in interest
rates) or fees thereon, or reduce the principal amount thereof, (ii) increase
the Revolving Commitment of any Bank over the amount thereof then in effect (it
being understood that a waiver of any condition, covenant, Default or Event of
Default shall not constitute a change in the terms of any Revolving Commitment
of any Bank), (iii) release or permit the release of any Collateral from the
Lien of the respective Security Instruments or any of the Guaranties, (iv)
amend, modify or waive any provision of this Section 22, (v) reduce the
percentage specified in the definition of Majority Banks (it being understood
and agreed that, with the consent of the Majority Banks, additional extensions
of credit pursuant to this Agreement may be included in the determination of
Majority Banks on substantially the same basis as the Revolving Commitments
(and related extensions of credit) are included on the Effective Date), (vi)
consent to the assignment or transfer by the Borrower of any of its rights and
obligations under this Agreement or (vii) waive, change the timing or amount
of, or extend any mandatory reduction in the Revolving Commitment. No provision
of Sections 2 or 14, or any other provisions relating to and issue of Letters
of Credit or the Agent may be modified without the consent of the Agent.

                    23. MULTIPLE COUNTERPARTS. This Agreement may be executed 
in a number of identical separate counterparts, each of which for all purposes
is to be deemed an original, but all of which shall constitute, collectively,
one agreement. No party to this Agreement shall be bound hereby until a
counterpart of this Agreement has been executed by all parties hereto.

                    24. CONFLICT. In the event any term or provision hereof is 
inconsistent with or conflicts with any provision of the Loan Documents, the
terms or provisions contained in this Agreement shall be controlling.

                    25. SURVIVAL. All covenants, agreements, undertakings, 
representations and warranties made in the Loan Documents, including this
Agreement, the Notes, the Guaranties or other documents and instruments referred
to herein shall survive all closings hereunder and shall not be affected by any
investigation made by any party.

                    26. PARTIES BOUND. This Agreement shall be binding upon 
and inure to the benefit of the parties hereto and their respective successors,


                                     -60-

assigns, heirs, legal representatives and estates, provided, however, that 
Borrower may not, without the prior written consent of the Banks, assign any 
rights, powers, duties or obligations hereunder.

<PAGE>   68
                    27. ASSIGNMENTS AND PARTICIPATIONS.

                                  (a) Each Bank shall have the right to sell,
           assign or transfer all or any part of its Note or Notes, its
           Revolving Commitments and its rights and obligations hereunder to an
           Eligible Assignee; provided, that with each sale, assignment or
           transfer (other than to an Affiliate, a Bank or a Federal Reserve
           Bank), shall require the consent of Borrower and Agent, which
           consents will not be unreasonably withheld, and the assignee,
           transferee or recipient shall have, to the extent of such sale,
           assignment, or transfer, the same rights, benefits and obligations
           as it would if it were such Bank and a holder of such Note,
           Revolving Commitment and rights and obligations, including, without
           limitation, the right to vote on decisions requiring consent or
           approval of all Banks or Majority Banks and the obligation to fund
           its Revolving Commitment; provided, further, that (1) each such
           sale, assignment, or transfer (other than to an Affiliate, a Bank or
           a Federal Reserve Bank) shall be in an amount not less than
           $5,000,000, (2) each remaining Bank shall at all times maintain
           Revolving Commitment then outstanding in a principal amount at least
           equal to $5,000,000; (3) no Bank may offer to sell its Note or
           Notes, Revolving Commitment, rights and obligations or interests
           therein in violation of any securities laws; and (4) no such
           assignments (other than to a Federal Reserve Bank) shall become
           effective until the assigning Bank and its assignees delivers to
           Agent and Borrower an Assignment and Acceptance and the Note or
           Notes subject to such assignment and other documents evidencing any
           such assignment. An assignment fee in the amount of $2,500 for each
           such assignment (other than to an Affiliate, a Bank or the Federal
           Reserve Bank) will be payable to Agent by assignor or assignee.
           Within five (5) Business Days after its receipt of copies of the
           Assignment and Acceptance and the other documents relating thereto
           and the Note or Notes, Borrower shall execute and deliver to Agent
           (for delivery to the relevant assignee) a new Note or Notes
           evidencing such assignee's assigned Revolving Commitment and if the
           assignor Bank has retained a portion of its Revolving Commitment, a
           replacement Note in the principal amount of the Revolving Commitment
           retained by the assignor (except as provided in the last sentence of
           this paragraph (a) such Note or Notes to be in exchange for, but not

                               REVOLVING NOTE

$_____________             Lafayette, Louisiana                  _________, 1997


         FOR VALUE RECEIVED, the undersigned, NEWPARK RESOURCES, INC., a
Delaware corporation (referred to herein as "Borrower") hereby unconditionally,
promises to pay to the order of ___________________, a _______________________
(referred to herein as "Bank"), at the offices of BANK ONE, LOUISIANA, N.A.
(the "Agent") in Lafayette, Louisiana, the principal sum of ___________ MILLION
AND NO/100 DOLLARS ($_____________), or so much thereof as may be advanced and
outstanding to or for the benefit of Borrower by Bank pursuant to the Restated
Credit Agreement (as hereinafter defined), in lawful money of the United States
of America together with interest from the date hereof until paid at the rates
specified in the Restated Credit Agreement. All payments of principal and
interest due hereunder are payable at the offices of Agent at 200 W. Congress,
Lafayette, Louisiana 70502, attention:  Energy Department, or at such other
address as Bank shall designate in writing to Borrower in accordance with the
Restated Credit Agreement.

         The principal and all accrued interest on this Revolving Note (the
"Note") shall be due and payable in accordance with the terms and provisions of
the Restated Credit Agreement.

         This Note is executed pursuant to that certain Restated Credit
Agreement dated of even date herewith among the Borrower, Guarantors, the Agent
and the Banks signatory thereto (the "Restated Credit Agreement"), and is one
of the Notes referred to therein.  This Note is secured by certain Security
Instruments (as such term is defined in the Restated Credit Agreement) of even
date herewith between Borrower, the Guarantors and Agent.  Reference is made to
the Restated Credit Agreement and the Security Instruments for a statement of
prepayment rights and obligations of Borrower, description of the properties
mortgaged and assigned, the nature and extent of such security and the rights
of the parties under the Security Instruments in respect to such security and
for a statement of the terms and conditions under which the due date of this
Note may be accelerated.  Upon the occurrence of an Event of Default, as that
term is defined in the Restated Credit Agreement and Security Instruments, the
holder hereof (subject to the provisions of the Restated Credit Agreement) (i)
may declare forthwith to be entirely and immediately due and payable the
principal balance hereof and the interest accrued hereon, and (ii) shall have
all rights and remedies under the Restated Credit Agreement and Security
Instruments.  This Note may be prepaid at any time in full or in part without
any premium or fee in accordance with the terms and provisions of the Restated
Credit Agreement.

         Regardless of any provision contained in this Note, the holder hereof
shall never be entitled to receive, collect or apply, as interest on this Note,
any amount in excess of the Maximum Rate (as such term is defined in the
Restated Credit Agreement), and, if the holder hereof ever receives, collects,
or applies as interest, any such amount which would be in excess of the Maximum
Rate, it
<PAGE>   78
shall be deemed a partial prepayment of principal and treated hereunder as
such; and, if the indebtedness evidenced hereby is paid in full, any remaining
excess shall forthwith be paid to Borrower.  In determining whether or not the
interest paid or payable, under any specific contingency, exceeds the Maximum
Rate, Borrower and the holder hereof shall, to the maximum extent permitted
under applicable law (i) characterize any non-principal payment as an expense,
fee or premium rather than as interest, (ii) exclude voluntary prepayments and
the effects thereof, and (iii) spread the total amount of interest throughout
the entire contemplated term of the obligations evidenced by this Note and/or
referred to in the Restated Credit Agreement so that the interest rate is
uniform throughout the entire term of this Note; provided that, if this Note is
paid and performed in full prior to the end of the full contemplated term
thereof and if the interest received for the actual period of existence thereof
exceeds the Maximum Rate, the holder hereof shall refund to Borrower the amount
of such excess or credit the amount of such excess against the indebtedness
evidenced hereby, and, in such event, the holder hereof shall not be subject to
any penalties provided by any laws for contracting for, charging, taking,
reserving or receiving interest in excess of the Maximum Rate.

         If any payment of principal or interest on this Note shall become due
on a Saturday, Sunday or public holiday or while the Agent is not open for
business, such payment shall be made on the next succeeding business day unless
required to be made on a different day pursuant to the provisions of the
Restated Credit Agreement and such extension of time shall in such case be
included in computing interest in connection with such payment.

         If this Note is placed in the hands of an attorney for collection, or
if it is collected through any legal proceeding at law or in equity or in
bankruptcy, receivership or other court proceedings, Borrower agrees to pay all
costs of collection, including, but not limited to, court costs and reasonable
attorneys' fees.

         Borrower and each surety, endorser, guarantor and other party ever
liable for payment of any sums of money payable on this Note, jointly and
severally waive presentment and demand for payment, notice of intention to
accelerate the maturity, notice of acceleration of the maturity, protest,
notice of protest and nonpayment, as to this Note and as to each and all
installments hereof, and agree that their liability under this Note shall not
be affected by any renewal or extension in the time of payment hereof, or in
any indulgences, or by any release or change in any security for the payment of
this Note, and hereby consent to any and all renewals, extensions, indulgences,
releases or changes.

         This Note shall be governed by and construed in accordance with the
applicable laws of the United States of America and the laws of the State of
Louisiana.

Credit Agreement") (hereinafter referred to as "Lenders"), guarantying the
Indebtedness (as defined) of NEWPARK RESOURCES, INC., a Delaware corporation
(hereinafter referred to as "Borrower").

                                  WITNESSETH:

         FOR VALUE RECEIVED, and in consideration of and for credit and
financial accommodations extended, to be extended, or continued to or for the
account of the above named Borrower, the undersigned Guarantor, whether one or
more, hereby jointly, severally and solidary, agrees as follows:

         SECTION 1.  CONTINUING GUARANTY OF BORROWER'S INDEBTEDNESS.  Guarantor
hereby absolutely and unconditionally agrees to, and by these presents does
hereby, guarantee the prompt and punctual payment, performance and satisfaction
of any and all loans, extensions of credit and/or other obligations that
Borrower may now and/or in the future owe to and/or incur in favor of Lenders
under or pursuant to the Restated Credit Agreement, including without
limitation the indebtedness of Borrower evidenced by (i) that certain Revolving
Note dated of even date herewith in the face amount of $25,000,000 made by
Borrower pursuant to the Restated Credit Agreement and payable to the order of
Hibernia, (ii) that certain Revolving Note dated of even date herewith in the
face amount of $29,500,000 made by Borrower pursuant to the Restated Credit
Agreement and payable to the order of Deutsche and (iii) that certain Revolving
Note dated of even date herewith in the face amount of $35,500,000 made by
Borrower pursuant to the Restated Credit Agreement and payable to the order of
Bank One, as said Revolving Notes may be renewed from time to time and in
effect or replaced pursuant to the provisions of the Restated Credit Agreement,
and whether such indebtedness and/or obligations are absolute or contingent,
liquidated or unliquidated, due or to become due, secured or unsecured, and
whether now existing or hereafter arising, of any nature or kind whatsoever
(with all of Borrower's indebtedness and/or obligations being hereinafter
individually and collectively referred to under this Agreement as "Borrower's
Indebtedness" or the "Indebtedness").

         Notwithstanding any other provision herein to the contrary but subject
to Section 2 hereof, the maximum principal amount of Borrower's Indebtedness in
favor of Lenders guaranteed by Guarantor under this Agreement is limited to the
greater of (i) NINETY MILLION AND NO/100 DOLLARS ($90,000,000.00) or (ii) the
Total Outstanding (as defined in the Restated Credit Agreement) under the
Restated Credit Agreement (interest, costs, and attorney's fees under
Borrower's Indebtedness are additionally guaranteed hereunder.)

         SECTION 2.  LIMITATION ON LIABILITY.  The liability of any Guarantor
hereunder with respect to the Indebtedness shall be limited to the maximum
amount of liability that can be incurred without rendering this Agreement, as
it relates to any Guarantor, voidable under applicable law relating to
fraudulent conveyance or fraudulent transfer, and not for any greater amount.
<PAGE>   81
         SECTION 3.  JOINT, SEVERAL AND SOLIDARITY LIABILITY.  Guarantor
further agrees that its obligations and liabilities for the prompt and punctual
payment, performance and satisfaction of all of Borrower's Indebtedness shall
be on a "joint and several" and "solidary" basis along with Borrower to the
same degree and extent as if Guarantor had been and/or will be a co-borrower,
co-principal obligor and/or co-maker of all of Borrower's Indebtedness.  In the
event that there is more than one guarantor under this Agreement, or in the
event that there are other guarantors, endorsers or sureties of all or any
portion of Borrower's Indebtedness, Guarantor's obligations and liabilities
hereunder shall be on a "joint and several" and "solidary" basis along with
such other guarantor or guarantors, endorsers and/or sureties.

         SECTION 4.  DURATION; CANCELLATION OF AGREEMENT.  This Agreement and
Guarantor's obligations and liabilities hereunder shall remain in full force
and effect until such time as each and every Indebtedness of Borrower shall be
paid, performed and/or satisfied in full, in principal, interest, costs and
attorneys' fees, or until such time as this Agreement may be cancelled or
otherwise terminated by Lenders under a written cancellation instrument in
favor of Guarantor (subject to the automatic reinstatement provision
hereinbelow).  Unless otherwise indicated under such a written cancellation
instrument, Lenders' agreement to terminate or otherwise cancel this Agreement
shall only effect and shall be expressly limited to Guarantor's continuing
obligations and liabilities to guarantee the prompt and punctual payment,
performance and satisfaction of Borrower's Indebtedness incurred, originated
and/or extended or committed to by Lenders after the date of such a written
cancellation instrument; with Guarantor remaining fully obligated and liable
under this Agreement for the prompt and punctual payment, performance and
satisfaction of any and all of Borrower's then outstanding Indebtedness
together with continuing assessment of interest thereon) that was incurred,
originated, extended or committed to prior to the date of such a written
cancellation instrument.  Nothing under this Agreement or under any other
agreement or understanding by and between Guarantor and Lenders, shall in any
way obligate, or be construed to obligate, Lenders to agree to the subsequent
termination or cancellation of Guarantor's obligations and liabilities
hereunder, it being fully understood and agreed by Guarantor that Lenders may,
within their sole and uncontrolled discretion and judgment, refuse to release
Guarantor from any of its obligations and liabilities under this Agreement for
any reason whatsoever as long as any of Borrower's Indebtedness remains unpaid
and outstanding.

         SECTION 5.  DEFAULT OF BORROWER.  Should Borrower default under any of
its Indebtedness in favor of Lenders as provided in the Restated Credit
Agreement, Guarantor unconditionally and absolutely agrees to pay the full then
unpaid amount of all of Borrower's Indebtedness guaranteed hereunder, in
principal, interest, costs and reasonable attorneys' fees.  Such payment or
payments shall be made immediately following demand by Lenders at Agent's
offices at 200 West Congress Street, Lafayette, Louisiana 70501.  Guarantor
hereby waives notice of acceptance of this Agreement and of any Indebtedness to
which it applies or may apply.  Guarantor further waives presentation and
demand for payment of Borrower's Indebtedness, notice of dishonor and of
nonpayment, notice of intention to accelerate, notice of acceleration, protest
and notice of protest, collection or institution of any suit or other action by
Lenders in collection thereof, including any notice of default in payment
thereof or other notice to, or demand for payment thereof on any party.
Guarantor additionally waives any and all rights and pleas of division and
discussion as provided under Louisiana State law, as well as, to the degree
applicable, any similar rights as may be provided under the laws of any other
state.

         SECTION 6.  GUARANTOR'S SUBORDINATION OF RIGHTS TO LENDERS.  In the
event that Guarantor should for any reason (i) make any payment for and on
behalf of Borrower under any of Borrower's Indebtedness, and/or (ii) make any
payments to Lenders in total or partial satisfaction of Guarantor's obligations
and liabilities hereunder, Guarantor hereby agrees that any and all rights that
Guarantor may have or acquire to collect or to be reimbursed by Borrower (or by
any guarantor,





                                      -2-
<PAGE>   82
endorser or surety of Borrower's Indebtedness), whether Guarantor's rights of
collection or reimbursement arise by way of subrogation to the rights of
Lenders or otherwise, shall in all respects be subordinate, inferior and junior
to Lenders' rights to collect and enforce payment, performance and satisfaction
of Borrower's then remaining Indebtedness, until such time as all of Borrower's
Indebtedness is fully paid and satisfied.  Upon the occurrence and continuance
of an Event of Default (as defined in the Restated Credit Agreement) any and
all amounts owed by Borrower to Guarantor shall in all respects be subordinate,
inferior and junior to Lenders' rights to collect and enforce payment,
performance and satisfaction of Borrower's then remaining Indebtedness, until
such time as all of Borrower's Indebtedness is fully paid and satisfied.
Guarantor further agrees to refrain from attempting to collect and/or enforce
any of Guarantor's aforesaid rights against Borrower (or any other guarantor,
surety or endorser of Borrower's Indebtedness), arising by way of subrogation
or otherwise, until such time as all of Borrower's then remaining Indebtedness
in favor of Lenders is fully paid and satisfied, in principal, interest, costs
and attorneys' fees.

         SECTION 7.  ADDITIONAL COVENANTS.  Guarantor further agrees that
Lenders may, at their sole option, at any time, and from time to time, without
the consent of or notice to Guarantor, or any one of them, or to any other
party, and without incurring any responsibility to Guarantor or to any other
party, and without impairing or releasing the obligations of Guarantor under
this Agreement:

                 (A)      Discharge or release any party (including, but not
limited to, Borrower or any guarantor under this Agreement) who is or may be
liable to Lenders for any of Borrower's Indebtedness;

                 (B)      Sell, exchange, release, surrender, realize upon or
otherwise deal with, in any manner and in any order, any collateral directly or
indirectly securing repayment of any of Borrower's Indebtedness;

                 (C)      Change the manner, place or terms of payment, or
change or extend the time of payment of or renew, as often and for such periods
as Lenders may determine, or after, any of Borrower's Indebtedness;

                 (D)      Settle or compromise any of Borrower's Indebtedness;

                 (E)      Subordinate and/or agree to subordinate the payment
of all or any of Borrower's Indebtedness or Lenders' security rights in and/or
to any collateral directly or indirectly securing any such indebtedness, to the
payment and/or security rights of any other present and/or future creditors of
Borrower;

                 (F)      Apply any sums paid to any of Borrower's
Indebtedness, with such payments being applied in such priority or with such
preferences as Lenders may determine in its sole discretion, regardless of what
Indebtedness of Borrower remains unpaid;

                 (G)      Take or accept any other security for any or all of
Borrower's Indebtedness; and/or

                 (H)      Enter into, deliver, modify, amend or waive
compliance with, any Instrument or arrangement evidencing, securing or
otherwise affecting, all or any part of Borrower's Indebtedness.

                 In addition, no course of dealing between Lenders and Borrower
(or any other guarantor, surety or endorser of Borrower's Indebtedness), nor
any failure or delay on the part of Lenders to exercise any of Lenders' rights
and remedies, or any other agreement or agreements by and





                                      -3-
<PAGE>   83
between Lenders and Borrower (or any other guarantor, surety or endorser) shall
have the affect of impairing or releasing Guarantor's obligations and
liabilities to Lenders or of waiving any of Lenders' rights and remedies.  Any
partial exercise of any rights and remedies granted to Lenders shall
furthermore not constitute a waiver of any of Lenders' other rights and
remedies, it being Guarantor's intent and agreement that Lenders' rights and
remedies shall be cumulative in nature.  Guarantor further agrees that, should
Borrower default under any of its Indebtedness, any waiver or forbearance on
the part of Lenders to pursue the rights and remedies available to Lenders
shall be binding upon Lenders only to the extent that Lenders specifically
agree to such waiver or forbearance in writing.  A waiver or forbearance on the
part of Lenders as to one event of default shall not constitute a waiver of
forbearance as to any other default.

         SECTION 8.  NO RELEASE OF GUARANTOR.  Guarantor's obligations and
liabilities under this Agreement shall not be released, impaired, reduced or
otherwise affected by, and shall continue in full force and effect,
notwithstanding the occurrence of any event, including without limitation any
one of the following events:

                 (A)      Death, insolvency, bankruptcy, arrangement,
adjustment, composition, liquidation, disability, dissolution or lack of
authority (whether corporate, partnership or trust) of Borrower (or any person
acting on Borrower's behalf), or any other guarantor, surety or endorser of any
of Borrower's Indebtedness;

                 (B)      Partial payment or payments of any amount due and/or
outstanding under any of Borrower's Indebtedness;

                 (C)      Any payment of Borrower or any other party to Lenders
is held to constitute a preferential transfer or a fraudulent conveyance under
any applicable law, or for any reason, Lenders is required to refund such
payment or pay such amount to Borrower or to any other person;

                 (D)      Any dissolution of Borrower or any sale, lease or
transfer of all or any part of Borrower's assets;

                 (E)      Any failure of Lenders to notify Guarantor of the
acceptance of this Agreement or of the making of loans or other extensions of
credit in reliance on this Agreement or of the failure of Borrower to make any
payment due by Borrower to Lenders;

                 (F)      Apply any sums paid to any of Borrower's
Indebtedness, with such payments being applied in such priority or with such
preferences as Lenders may determine in its own discretion, regardless of what
Indebtedness of Borrower remains unpaid;

                 (G)      Take or accept any other security for any or all of
Borrower's Indebtedness; and/or

                 (H)      Enter into, deliver, modify, amend or waive
compliance with, any Instrument or arrangement evidencing, securing or
otherwise affecting, all or any part of Borrower's Indebtedness.

                 This Agreement and Guarantor's obligations and liabilities
hereunder shall continue to be effective, and/or shall automatically and
retroactively be reinstated if a release or discharge has occurred, as the case
may be, if at any time any payment or part thereof to Lenders with respect to
any of Borrower's Indebtedness is rescinded or must otherwise be restored by
Lenders pursuant to any insolvency, bankruptcy, reorganization, receivership,
or any other debt relief granted to Borrower or to





                                      -4-
<PAGE>   84
any other party.  In the event that Lenders must rescind or restore any payment
received by Lenders in satisfaction of Borrower's Indebtedness, any prior
release or discharge from the terms of this Agreement given to Guarantor shall
be without effect, and this Agreement and Guarantor's obligations and
liabilities hereunder shall automatically be renewed or reinstated and shall
remain in full force and effect to the same degree and extent as if such a
release or discharge was never granted.  It is the intention of Lenders and
Guarantor that Guarantor's obligations and liabilities hereunder shall not be
discharged except by Guarantor's full and complete performance of such
obligations and liabilities and then only to the extent of such performance.

         SECTION 9.  ENFORCEMENT OF GUARANTOR'S OBLIGATIONS AND LIABILITIES.
Guarantor agrees that, should Lenders deem it necessary to file an appropriate
collection action to enforce Guarantor's obligations and liabilities under this
Agreement, Lenders may commence such a civil action against Guarantor without
the necessity of first (i) attempting to collect Borrower's Indebtedness from
Borrower or from any other guarantor, surety or endorser, whether through
filing of suit or otherwise, (ii) attempting to exercise against any collateral
directly or indirectly securing repayment of any of Borrower's Indebtedness,
whether through the filing of an appropriate foreclosure action or otherwise,
or (iii) including Borrower or any other guarantor, surety or endorser of any
of Borrower's Indebtedness as an additional party defendant in such a
collection action against Guarantor.  If there is more than one guarantor under
this Agreement, each guarantor additionally agrees that Lenders may file an
appropriate collection and/or enforcement action against any one or more of
them, without impairing the rights of Lenders against any other guarantor under
this Agreement.  In the event that Lenders should ever deem it necessary to
refer this Agreement to an attorney-at-law for the purpose of enforcing
Guarantor obligations and liabilities hereunder, or of protecting or preserving
Lenders' rights hereunder, Guarantor (and each of them, on a joint, several and
solidary basis) agrees to reimburse Lenders for the reasonable fees of such an
attorney.  Guarantor additionally agrees that Lenders shall not be liable for
failure to use diligence in the collection of any of Borrower's Indebtedness or
any collateral security therefor, or in creating or preserving the liability of
any person liable on any such Indebtedness, or in creating, perfecting or
preserving any security for any such Indebtedness.

         SECTION 10.  ADDITIONAL DOCUMENTS.  Upon the reasonable request of
Lenders, Guarantor will, at any time, and from time to time, duly execute and
deliver to Lenders any and all such further instruments and documents, and
supply such additional information as may be necessary or advisable in the
opinion of Lenders, to obtain the full benefits of this Agreement.

         SECTION 11.  TRANSFER OF INDEBTEDNESS.  This agreement is for the
benefit of Lenders and for such other person or persons as may from time to
time become or be the holders of any of Borrower's Indebtedness hereby
guaranteed and this Agreement shall be transferable and negotiable, with the
same force and effect and to the same extent as Borrower's Indebtedness may be
transferable, it being understood that, upon the transfer or assignment by
Lenders of any of Borrower's Indebtedness hereby guaranteed, the legal holder
of such Indebtedness shall have all the rights granted to Lenders under this
Agreement.

         Guarantor hereby recognizes and agrees that Lenders may, from time to
time, one or more times, transfer all or any portion of Borrower's Indebtedness
to one or more third parties.  Such transfers may include, but are not limited
to, sales of a participation or syndication interest in such Indebtedness in
favor of one or more third parties.  Guarantor specifically agrees and consents
to all such transfers and assignments and Guarantor further waives any
subsequent notice of and right to consent to any such transfers and assignments

the purchaser under any participation agreement governing the sale of such a
participation or syndication interest.  Guarantor further waives any right of
offset that Guarantor may have against Lenders and/or any purchaser of such a
participation or syndication interest in Borrower's Indebtedness and Guarantor
unconditionally agrees that either Lenders or such a purchaser may enforce
Guarantor's obligations and liabilities under this Agreement, irrespective of
the failure or insolvency of Lenders or any such purchaser.  Guarantor further
agrees that, upon any transfer of all or any portion of Borrower's
Indebtedness, Lenders may transfer and deliver any and all collateral securing
repayment of such Indebtedness including, but not limited to, any collateral
provided by Guarantor) to the transferee of such Indebtedness and such
collateral (again, including but not limited to Guarantor's collateral) shall
secure any and all of Borrower's Indebtedness in favor of such transferee.
Guarantor additionally agrees that, after any such transfer or assignment has
taken place, Lenders shall be fully discharged from any and all liability and
responsibility to Borrower (and Guarantor) with respect to such collateral, and
the transferee thereafter shall be vested with all the powers and rights with
respect to such collateral.

repayment of Guarantor's obligations and liabilities under this Agreement,
Guarantor hereby grants Lenders, as well as their successors and assigns, the
right to apply, upon the occurrence of an Event of Default under the Restated
Credit Agreement and the expiration of any applicable grace period allowed to
cure the Event of Default, any and all funds that Guarantor may then have on
deposit with or in the possession or control of any Lender and its successors
or assigns (with the exception of funds deposited in IRA, pension or other
tax-deferred deposit accounts), towards repayment of any of Borrower's
Indebtedness subject to this Agreement.

         SECTION 13.  CONSTRUCTION.  The provisions of this Agreement shall be
in addition to and cumulative of, and not in substitution, novation or
discharge of, any and all prior or contemporaneous guaranty or other agreements
by Guarantor (or any one or more of them), in favor of Lenders or assigned to
Lenders by others, all of which shall be construed as complementing each other.
Nothing herein contained shall prevent Lenders from enforcing any and all such
guaranties or agreements in accordance with their respective terms.

         SECTION 14.  AMENDMENT.  No amendment, modification, consent or waiver
of any provision of this Agreement, and no consent to any departure by
Guarantor therefrom, shall be effective unless the same shall be in writing

only to the specific instance and for the specific purpose for which given.

         SECTION 15.  SUCCESSORS AND ASSIGNS BOUND.  Guarantor's obligations
and liabilities under this Agreement shall be binding upon Guarantor's
successors, heirs, legatees, devisees, administrator executors and assigns.

inure to the benefit of Lenders' successors and assigns, as well as to any and
all subsequent holder or holders of any of Borrower's Indebtedness subject to
this Agreement.

         SECTION 16.  CAPTION HEADING.  Caption headings of the sections of

         SECTION 18.  SEVERABILITY.  If any provision of this Agreement is held
to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof; such provision shall be fully severable, this Agreement
shall be construed and enforceable as if the illegal, invalid or unenforceable
provision had never comprised a part of it, and the remaining provisions of
this Agreement shall remain in full force and effect and shall not be affected
by the illegal, invalid or unenforceable provision or by its severance
herefrom.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as a part of this Agreement, a
provision as similar in terms to such illegal, invalid or unenforceable
provision as may be possible and legal, valid and enforceable.

         IN WITNESS WHEREOF, Guarantor has executed this Agreement in favor of
Lenders on the day, month, and year first written above.
