Item 5.  Other Events.

      As previously reported, in July 1998, U S Liquids Inc. (the "Company")
commenced an arbitration proceeding against Newpark Resources, Inc. ("Newpark")
for failure to satisfy its delivery and payment obligations under a certain NOW
Disposal Agreement dated June 4, 1996 (the "Disposal Agreement"). Specifically,
the Company alleged that Newpark had fallen short of its delivery obligations
under the Disposal Agreement. The Company had requested that the arbitrators
enter an order (i) declaring that Newpark had breached the Disposal Agreement
and no condition existed which would excuse Newpark's breach, and (ii) awarding
the Company damages. On September 22, 1998, the Company and Newpark settled this
arbitration proceeding.

      Under the terms of the settlement, Newpark and the Company entered into a
thirty-three month agreement, pursuant to which Newpark will pay to the Company
at least $30 million. This amount, which may be increased based upon future
increases in the consumer price index, will be paid to the Company in monthly
installments beginning in September 1998 and continuing through June 2001. These
payments will permit Newpark to deliver to the Company for processing and
disposal specified amounts of oilfield waste. At Newpark's option, the term of
the agreement may be extended for up to two additional years. This thirty-three
month agreement replaces Newpark's obligations under the Disposal Agreement.
<PAGE>
      As part of the settlement, the Company secured the right to immediately
enter into the business of cleaning tanks, barges and other vessels and
containers used in the storage and/or transportation of oilfield waste and
acquired certain assets used in the business in exchange for a payment of $2.15
million. Prior to this settlement, the Company was contractually prohibited from
engaging in any such cleaning business within the states of Louisiana, Texas,
Mississippi and Alabama and the Gulf of Mexico.

      The settlement does not substantially alter the Company's contractual
obligation not to engage, directly or indirectly, in (i) the collection,
transfer, transportation, treatment or disposal of oilfield waste generated in a
marine environment or transported in marine vessels, or (ii) the remediation and
closure of oilfield waste pits business, in each case within the states of
Louisiana, Texas, Alabama and Mississippi and the Gulf of Mexico. However, the
settlement agreements provide that these noncompete provisions shall terminate
immediately if Newpark fails to make in a timely manner all payments required to
be made to the Company under the terms of the settlement.

      As part of the settlement, the parties also reduced the term of the lease
agreements pursuant to which Newpark leases the dock facilities at the Company's
landfarms in Bourg, Louisiana, Mermentau, Louisiana and Bateman Island,
Louisiana. These leases will now terminate on June 30, 2001, as opposed to
August 31, 2021.

      The foregoing discussion is only a summary and is qualified in its
entirety by reference to Exhibits 99.1, 99.2, 99.3, 99.4 and 99.5 to this
Current Report on Form 8-K filed herewith.

except as provided in Section 12.1. Failure to make Payment in Full and on Time
under this Section constitutes a breach of this Agreement.

            2.2.2 SECOND CONTRACT YEAR.

      a.    The Disposal Amount owed for the second Contract Year shall be no
            less than $10 million except as provided in Section 12.1. The
            Disposal Amount for the first and second Quarters of the second
            Contract Year shall total $5 million except as provided in Section
            12.1. During the first and second Quarters of the second Contract
            Year, NESI shall pay the Disposal Amount in six equal monthly
            installments due on or before July 1, 1999, August 2, 1999,
            September 1, 1999, October 1, 1999, November 1, 1999, and December
            1, 1999, respectively, except as provided in Section 12.1.

      b.    On the first Adjustment Date, January 3, 2000, the Disposal Amount
            for the remainder of the second Contract Year shall be adjusted by
            (i) adding to the Base Rate 70% of the positive amount, if any,
            determined by subtracting the Base Rate from the Consumer Price
            Index in effect on that Adjustment Date, (ii) dividing said sum by
            the Base Rate and (iii) multiplying the result by $5 million, except
            as provided in Section 12.1. In the event that the net change in the
            Consumer Price Index is negative, the Disposal Amount for the third
            and fourth Quarters of the second Contract Year shall total $5
            million except as provided in Section 12.1. NESI shall pay the
            remainder of the Disposal Amount for the second Contract Year in six
            equal monthly installments due on or before January 3, 2000,
            February 1, 2000, March 1, 2000, April 3, 2000, May 1, 2000, and
            June 1, 2000, respectively, except as provided in Section 12.1.
            Failure to make Payment in Full and on Time under this Section
            constitutes a breach of this Agreement.

            2.2.3 THIRD CONTRACT YEAR. The Disposal Amount owed for the third
Contract Year shall be no less than $8 million except as provided in Section
12.1. On the first Adjustment Date, January 3, 2000, the Disposal Amount for the
third Contract Year shall be adjusted by (i) adding to the Base Rate 70% of the
positive amount, if any, determined by subtracting the Base Rate from the
Consumer Price Index in effect on that Adjustment Date, (ii) dividing said sum
by the Base Rate, and (iii) multiplying the results by $8 million except as
provided in Section 12.1. In the event that the net change in the Consumer Price
Index is negative, the Disposal Amount for the third Contract Year shall be $8
million, except as provided in Section 12.1. NESI shall pay the Disposal Amount
in twelve equal monthly installments due on or before July 3, 2000, August 1,
2000, September 1, 2000,

respectively, except as provided in Section 12.1. Failure to make Payment in
Full and on Time under this Section constitutes a breach of this Agreement.

            2.2.4 ADDITIONAL CONTRACT YEARS. Should NESI exercise its option to
extend the term of the Agreement in accordance with Section 5.2, the Disposal
Amount shall be no less than $8 million for each additional Contract Year except
as provided in Section 12.1. On the second Adjustment Date, June 30, 2001, the
Disposal Amount owed for the fourth Contract Year shall be adjusted by (i)
dividing 100% of the Consumer Price Index in effect on that date by 100% of the
Base Rate; and (ii) multiplying the result by $8 million except as provided in
Section 12.1. In the event the net change in the Consumer Price Index is
negative, the Disposal Amount for the fourth Contract Year shall be $8 million,
except as provided in Section 12.1. NESI shall pay the Disposal Amount for the
fourth Contract Year in twelve equal monthly installments due on or before July
2, 2001, August 1, 2001, September 3, 2001, October 1, 2001, November 1, 2001,

2002, May 1, 2002, and June 3, 2002, respectively, except as provided in Section
12.1. Should NESI exercise its option to extend the Agreement for a fifth
Contract Year, the Disposal Amount for that Contract Year shall be adjusted on
the third Adjustment Date, June 30, 2002 by (i) dividing 100% of the Consumer
Price Index in effect on that date by 100% of the Base Rate; and (ii)
multiplying the result by $8 million. In the event the net change in the
Consumer Price Index is negative, then the Disposal Amount for the fifth
Contract Year shall be $8 million except as provided in Section 12.1. NESI shall
pay the Disposal Amount for the fifth Contract Year in twelve equal monthly
installments due on or before July 1, 2002, August 1, 2002, September 2, 2002,
October 1, 2002, November 1, 2002, December 2, 2002, January 1, 2003, February
3, 2003, March 3, 2003, April 1, 2003, May 1, 2003, and June 2, 2003,
respectively, except as provided in Section 12.1. Failure to make Payment in
Full and on Time under this Section constitutes a breach of this Agreement.

      2.3 OBLIGATION TO PAY. NESI's obligation to make Payment in Full and on
Time where required by any Section in this Agreement exists without regard to
whether NESI exercises its option to deliver NOW to USL in accordance with
Section 3.1. Failure to make Payment in Full and on Time in every instance for
any reason whatsoever constitutes a breach of this Agreement and shall not
entitle NESI to any offsets, carryovers, or counterclaims of any kind.

                                  ARTICLE III
                     DISPOSAL, VOLUME AND PREVAILING RATE

      3.1   NOW DELIVERY.

            3.1.1 DELIVERY OPTION.

      a.    NESI may, at its option, deliver to USL for disposal at the Bateman
            Island Landfarm a maximum amount of NOW equal to the Annual Volume
            for such Contract Year at no cost without prior notice or approval.
            Subject to the terms and conditions and the

                                      5
<PAGE>
            limitations set forth in this Agreement, USL shall accept for
            disposal at the Bateman Island Landfarm all NOW delivered by or on
            behalf of NESI; provided, however, that in no event shall USL be
            obligated to accept from or on behalf of NESI for disposal at any
            Landfarm (i) more than the Quarterly Volume during any one Quarter
            as determined in Sections 3.3 and 3.4, or (ii) more than 25% of the
            Annual Volume during any one Quarter. Failure by NESI to deliver the
            Quarterly Volume in any Quarter shall constitute waiver of NESI's
            option to deliver the remainder for that Quarter. Failure to deliver
            the full Quarterly or Annual Volume shall not result in any
            carryforward or increase in the Quarterly or Annual Volume in the
            succeeding Quarter or Contract Year.

      b.    NESI shall have the right to deliver a volume no more than 10% of
            the Quarterly Volume for that Quarter to the Bourg Landfarm at no
            cost, subject to Section 3.1.1.a, and prior notice by NESI in
            accordance with Section 13.5.2, of 48 hours if such delivery shall
            arrive by marine transportation; or

      c.    NESI shall have the right to deliver a volume no more than 10% of
            the Quarterly Volume for that Quarter to the Mermentau Landfarm at
            no cost, subject to Section 3.1.1.a and prior written approval by
            USL, which approval will not be unreasonably withheld.

            3.1.2 OBLIGATION TO PAY. NESI is obligated to pay the Disposal
Amount regardless of the volume of NOW, if any, delivered to or accepted by USL
in accordance with this Section 3.1, except as provided in Section 12.1. Failure
by NESI to exercise its option to deliver NOW to USL for disposal shall not
alter, lessen, decrease, alleviate, or relieve NESI of its obligation to pay USL
in accordance with Article II. NESI shall make all payments in accordance with
Article II without regard to the volume of NOW, if any, offered or delivered to
USL for disposal.

      3.2   PREVAILING RATE.

            3.2.1 FIRST CONTRACT YEAR. The Prevailing Rate for the first
Contract Year shall be $5.71 per barrel NOW delivered to USL for disposal, net
of all currently applicable taxes. The Prevailing Rate shall never be less than
$5.71 per barrel NOW during the term of this Agreement.

            3.2.2 ADJUSTMENT OF PREVAILING RATE. On the first Adjustment Date,
January 3, 2000, the Prevailing Rate shall be adjusted by (i) adding to the Base
Rate 70% of the positive amount, if any, determined by subtracting the Base Rate
from the Consumer Price Index as of the first Adjustment Date, (ii) dividing
said sum by the Base Rate, and (iii) multiplying the result by $5.71. If the net
change in the Consumer Price Index is negative, then the Prevailing Rate shall
be $5.71 per barrel NOW until June 30, 2001.

            3.2.3 ADDITIONAL CONTRACT YEARS. Should NESI exercise its option to
extend the term of the Agreement in accordance with Section 5.2, then the
Prevailing Rate shall be calculated as follows. On the second and third
Adjustment Dates, the Prevailing Rate for the fourth and fifth

                                      6
<PAGE>
Contract Years, respectively, shall be adjusted by (i) dividing 100% of the
Consumer Price Index in effect on the respective Adjustment Date by 100% of the
Base Rate; and (ii) multiplying the result by $5.71. If the net change in the
Consumer Price Index is negative, then the Prevailing Rate is $5.71.

      3.3 ANNUAL VOLUME. The Annual Volume for the first Contract Year shall be
1,401,000 barrels of NOW. The Annual Volume for the second Contract Year shall
be no more than 1,751,000 barrels of NOW. On the first Adjustment Date, January
3, 2000, the Annual Volume for the second Contract Year shall be adjusted by
dividing the adjusted Disposal Amount for the third and fourth Quarters in the
second Contract Year as calculated under Section 2.2.2 by the adjusted
Prevailing Rate as calculated under Section 3.2.2. In each succeeding Contract
Year, the Annual Volume for that year shall be calculated on the Adjustment Date
preceding that Contract Year by dividing the Disposal Amount for that Contract
Year by the Prevailing Rate for that Contract Year.

      3.4 QUARTERLY VOLUME. The Quarterly Volume for each Contract Year shall be
calculated by dividing the Annual Volume by four.

      3.5   EXCESS VOLUME.

            3.5.1 ACCEPTANCE OPTION. During any Contract Year, USL has the
option, but not the obligation, to accept for disposal an amount of NOW from
NESI in excess of the Quarterly Volume. Should USL exercise its option to accept
delivery of an amount of NOW in excess of the Quarterly Volume, NESI agrees to
pay the Prevailing Rate for disposal of the excess volume. In the event USL
elects not to accept NOW delivered by NESI in excess of the Quarterly Volume
during any Quarter, USL may reject such waste in accordance with Section 6.6 of
this Agreement without causing (i) the Annual Volume for any Contract Year to
increase or (ii) the Disposal Amount to decrease.

            3.5.2 INVOICE FOR EXCESS VOLUME: USL shall invoice NESI for fees
incurred from the disposal of volume in excess of the Quarterly Volume to be
paid no later than 30 days from receipt of the invoice. Failure to pay USL in
accordance with the terms of the invoice shall constitute a breach of this
Agreement.

      3.6 RADIUM CONCENTRATION. Notwithstanding anything contained in this
Agreement to the contrary, USL shall not be obligated to accept NOW from NESI at
any Landfarm where such NOW (i) when combined with other NOW in an individual
treatment cell, would cause the weighted average concentration of Radium 226 or
228 to exceed 5 pCi/gm, excluding background, or (ii) would require the loading
of two or more treatment cells simultaneously to prevent the weighted average
concentration of Radium 226 or 228 from exceeding 5 pCi/gm, excluding
background. In the event NESI delivers NOW contravening the foregoing sentence,
USL shall have the right, but not the obligation, to reject such NOW in
accordance with Section 6.6.

      3.7 VARIANCE. The parties agree to cooperate to minimize monthly variances
in NOW delivered for disposal at the Landfarms.

                                      7

                                  ARTICLE IV
                       SERVICES, LEVIES, AND INSPECTION

      4.1 ADDITIONAL SERVICES; DISPOSAL OF INJECTABLE SALTWATER. Pursuant to
this Agreement, USL will perform standard off-loading and customary handling
services associated with disposal of NOW up to, and including, the Annual Volume
at no additional charge. USL will perform additional services upon request of
NESI at the posted rates of USL for such services, or at such other rates as the
parties may mutually agree upon. All charges for such additional services shall
be in addition to and independent of the Prevailing Rate. USL will accept
injectable saltwater at the Landfarms for disposal upon request of NESI at the
posted rates of USL for disposal of injectable saltwater, or at such other rates
as the parties may mutually agree upon. All charges for disposal of injectable
saltwater shall be in addition to and independent of the Prevailing Rate.

      4.2 DISPOSAL OF WASHWATER. NESI shall pay USL to dispose of Washwater at
the rate of $1.50 per barrel of Washwater. On each Adjustment Date, the rate
shall be adjusted in the same manner as the Prevailing Rate is adjusted in
Sections 3.2.2 and 3.2.3. The disposal of Washwater shall be for the benefit of
NESI, and USL shall provide NESI with billing information specified by NESI to
enable NESI to bill the customer or customers for whose account any related
cleaning services were performed.

      4.3 INVOICE FOR ADDITIONAL SERVICES: USL shall invoice NESI on a monthly
basis for fees or expenses incurred from any services performed pursuant to
Section 4.1 or 4.2 to be paid no later than 30 days from receipt of the invoice.
Failure to pay USL in accordance with the terms of the invoice shall constitute
a breach of this Agreement.

      4.4   EXTRAORDINARY LEVIES.

            4.4.1 TAXES. Notwithstanding anything to the contrary contained
herein, if during the term of this Agreement there is levied upon USL or any of
its Affiliates or upon the operations of USL any tax, fee, assessment, or other
charge (other than income taxes applicable generally) by any governmental
authority, which tax, assessment or charge increases USL's costs to operate any
Landfarm, USL shall notify NESI of the cause and the per barrel amount of the
cost increase. If NESI chooses to deliver NOW to USL following the effectiveness
of the tax, fee, assessment or other charge, USL will invoice NESI for and NESI
will be obligated to pay NESI's share of the cost increase for so long as such
tax, fee, assessment or other charge remains in effect as follows: (i) with
respect to any cost increase resulting from any tax, fee, assessment or other
charge levied by a governmental authority on a per barrel basis, an amount
determined by multiplying such per barrel charge (but not more than the increase
in cost resulting therefrom) by the number of barrels of NOW delivered by NESI
to USL; and (ii) with respect to any tax, fee, assessment or other charge levied
by a governmental authority on any basis other than per barrel, NESI's
proportionate share of the cost increase resulting from such tax, fee,
assessment or charge. NESI's proportionate share shall be calculated as follows:
(a) if such tax, fee, assessment or other charge increases the cost to operate
the Bateman Island Landfarm, the NESI's proportionate share shall be calculated
by (i) dividing the number of barrels of NOW delivered to USL by NESI by the
Annual Volume plus the total number

                                      8
<PAGE>
of barrels in excess of the Annual Volume delivered to USL by NESI and accepted
by USL and (ii) multiplying the result by the amount of the cost increase
resulting from the tax, fee, assessment, or other charge; (b) if such tax, fee,
assessment or other charge increases the cost to operate the Bourg and/or
Mermentau Landfarm, then NESI's proportionate share shall be calculated by (i)
dividing the number of barrels of NOW delivered to USL by NESI to that Landfarm
by the total number of barrels delivered to that Landfarm by any entity and (ii)
multiplying the result by the amount of the cost increase at that Landfarm
resulting from the tax, fee, assessment, or other charge. Such payment or
reimbursement shall not alter the Annual Volume nor alter the Disposal Amount.

            4.4.2 LANDFARM ENVIRONMENTAL REGULATIONS. Notwithstanding anything
to the contrary contained herein, if during the term of this Agreement there is
a substantial change in regulatory requirements related to the waste disposal
business having general applicability to the handling, treatment or disposal of
NOW, which change increases in a material manner USL's costs to operate any
Landfarm, (i) USL shall notify NESI of the cause and the per barrel amount of
the cost increase and, to the extent that NESI chooses to deliver NOW to USL,
(ii) USL will invoice NESI for NESI's proportionate share of the cost increase
and NESI will be obligated to pay such amount so long as such cost increase
remains in effect. NESI's proportionate share shall be calculated as follows:
(a) if such change in regulatory requirements increases costs to operate the
Bateman Island Landfarm, then NESI's proportionate share shall be calculated by
(i) dividing the number of barrels of NOW delivered to USL by NESI by the Annual
Volume plus the total number of barrels in excess of the Annual Volume delivered
to USL by NESI and accepted by USL and (ii) multiplying the result by the amount
of the cost increase; (b) if such change in regulatory requirements increases
costs to operate the Bourg and/or Mermentau Landfarm, then NESI's proportionate
share shall be calculated by (i) dividing the number of barrels of NOW delivered
to USL by NESI to that Landfarm by the total number of barrels delivered to that
Landfarm by any entity and (ii) multiplying the result by the amount of the cost
increase at that Landfarm. Failure to pay USL in accordance with the terms of
the invoice shall constitute a breach of this Agreement.

            4.4.3 RIGHT OF INSPECTION. In the event USL notifies NESI of a cost
increase pursuant to this Section 4.4, NESI shall have the right to conduct a
reasonable review of the calculations, working papers and the books and records
related to the determination of such fee increase. All costs of such review
shall be borne exclusively by NESI.

                                   ARTICLE V
                                     TERM

      5.1 TERM. The term of this Agreement shall be for a period of three years,
commencing on the Effective Date and ending on June 30, 2001. Each party shall
notify the other of the pending expiration of the Agreement no later than seven
months before such expiration.

      5.2   EXTENSION OF TERM.

            5.2.1 OPTION. At its option, NESI may extend the term of this
Agreement by one or two additional one-year terms upon giving written notice of
such intent at least six months prior

                                      9
<PAGE>
to the expiration of the Agreement. Should NESI exercise its option to extend
the Term of this Agreement for a second additional one-year term, the second
additional one-year term must immediately succeed the first. For each Contract
Year of the extended term, NESI shall recover 100% of any revenues received by
USL and its Affiliates during each Quarter of that Contract Year from the
"Business," as that term is defined in the Noncompetition Agreement of September
16, 1998. USL shall reimburse NESI in the proper amount within 30 days of the
end of each Quarter.

            5.2.2 EFFECT OF BREACH OF NONCOMPETITION AGREEMENT. If USL breaches
the Noncompetition Agreement dated September 16, 1998, by engaging in
"Business," as that term is defined therein after the Effective Date, USL must
pay to NESI any and all revenues received from activities that constitute such
breach. Breach of the Noncompetition Agreement shall have no effect whatsoever
on NESI's payment obligations under this Agreement. USL shall use all reasonable
commercial efforts to enforce the Seller Noncompetition Agreement and the Buyer
Noncompetition Agreement, both dated December 13, 1996 by and between Sanifill,
Inc. and USL.

                                  ARTICLE VI
                             OPERATING PROCEDURES

      6.1 COMPLIANCE WITH OPERATING PROCEDURES. NESI and its Affiliates shall
comply in all material respects with and abide by, and shall require their
employees, servants, agents, representatives, contractors, subcontractors,
haulers and transporters to comply in all material respects with and abide by,
all applicable federal, state and local laws, ordinances, permits, regulations,
directives, codes, standards and requirements relating to the subject matter of
this Agreement or the performance of services hereunder, as well as all of USL's
rules, regulations, procedures and guidelines, written or oral, as the same may
be reasonably adopted and modified from time to time, including, without
limitation, all safety and/or security regulations, practices and procedures,
and all procedures reasonably adopted by USL in compliance with its permits or
utilized by USL in the inspection, sampling and testing of material delivered to
any Landfarm for disposal.

      6.2 INSPECTION AND TESTING BY NESI; NOTIFICATION. NESI agrees that it
shall inspect and test all materials accepted, acquired, taken possession of,
procured, directed, controlled or otherwise received by it from third party
generators or other parties for disposal (with the exception of any NOW produced
by third-party generators which NESI or its Affiliates treat and dispose of on
the site at which the NOW was generated) to the extent required by applicable
federal, state and local laws, ordinances, permits, regulations, directives,
codes, standards and requirements. NESI shall promptly notify USL if it becomes
aware of any unusual or special characteristics of any materials being delivered
to any Landfarm which cause such materials to require special treatment,
handling or care. Upon request by USL, NESI shall provide copies of all
inspection and test results relating to material to be disposed of at any
Landfarm under the terms of this Agreement to USL upon delivery.

      6.3 SHIPMENT AND DELIVERY OF NOW. NESI, its Affiliates and/or its
contractors and subcontractors shall be responsible for proper containerization,
preparation and labeling for shipment, shipment, transportation and delivery to
any Landfarm, and shall comply fully with all applicable federal, state and
local laws, ordinances, permits, regulations, directives, codes, standards and

                                      10
<PAGE>
requirements in making such delivery to any Landfarm. USL and its Affiliates
undertake no responsibility whatsoever for the preparation, handling or
transportation of any material prior to acceptance of delivery as hereinafter
provided.

      6.4   INSPECTIONS.

            6.4.1 BARGES. Upon arrival of any barge transporting material to a
Landfarm at the direction of NESI or any of its Affiliates, USL shall have the
right to have an independent third-party inspector selected by USL undertake an
inspection of the barge transporting material to the Landfarm for the purpose of
determining (a) the volume of materials delivered and (b) the condition of the
barge on arrival at the Landfarm. The costs of such inspector shall be split
evenly between NESI and USL, and NESI's portion of such expense shall be
included on the monthly invoices prepared by USL in accordance with Section 4.3.
Before any materials are off-loaded from the barge or any inspection or testing
is undertaken by USL, the independent inspector will provide the authorized
representatives of NESI and USL with an inspector's report indicating the time
and date, the barge identification number and volume of waste materials in the
barge. The authorized representatives of the parties will indicate their
acceptance of the inspector's report by signing the report. In the event either
authorized representative disagrees with the volume determination, either
authorized representative may request that an additional independent third-party
inspector prepare an inspector's report, the cost of which shall be borne by the
party requesting the same. If the parties are unable to agree on the actual
volume of waste after the preparation of the second inspector's report, the two
independent inspectors shall select a third independent inspector to prepare an
inspector's report, the cost of which will be borne half by NESI and half by
USL. The final volume determination shall be that volume agreed upon by the
majority of the independent inspectors that have inspected the barge. If the
barge appears to be damaged in any significant respect, the inspector shall
summarize the apparent damage and take photographs as appropriate to evidence
the scope of the damage. The authorized representative of NESI shall approve
such damage summary by executing the same prior to the time any material is
off-loaded from the barge. With regard to barges owned and operated by NESI, USL
agrees that it shall not exercise its right to implement the procedures set
forth in this Section 6.4.1 unless the parties have previously had a dispute or
disagreement relating to the quantity of materials delivered to a Landfarm by
NESI or the condition of a barge owned and operated by NESI and such dispute or
disagreement was not amicably resolved within 30 days.

            6.4.2 TRUCKS. Upon arrival of a truck transporting material to a
Landfarm on behalf of NESI or any of its Affiliates, USL personnel shall
undertake an inspection to determine the volume of materials delivered. Before
any materials are off-loaded from the truck or any inspection or testing is
undertaken by USL, USL shall prepare a receipt indicating the time and date and
the volume of materials in the truck. The driver of the truck shall indicate his
or her acceptance of the receipt by signing the receipt. In the event the driver
disagrees with the volume determination, USL shall have the option of (i)
accepting the volume stated by the driver and preparing a receipt evidencing
such volume to be signed by the driver or (ii) rejecting such materials in
accordance with Section 6.6.

      6.5 INSPECTION AND TESTING OF MATERIAL. After all inspections, if any,
pursuant to Section 6.4 have been concluded, USL shall conduct inspections,
testing and sampling using such equipment

                                      11
<PAGE>
and procedures as are required by or consistent with its permits. USL may rely
exclusively on the results of its inspection in determining whether materials
delivered may be disposed at the Landfarm in accordance with its permits and
this Agreement. NESI authorizes USL to retain samples and all data relating
thereto, including test results, for so long as required by federal, state or
local law, ordinance, permit, regulation, directive, code, standard or
requirement and additionally for so long as USL in its sole discretion shall
determine.

      6.6   ACCEPTANCE OR REJECTION OF MATERIAL.

            6.6.1 ACCEPTANCE. USL shall only be obligated to accept waste
materials at the Landfarm which are permissible under the permit requirements of
that Landfarm at the time of delivery. For a period of ten days after the date
of delivery, USL shall have the right to reject (or revoke any prior acceptance)
all or any part of a shipment of material delivered by or on behalf of NESI to
the Landfarm if (i) such material is not in accordance with the terms of this
Agreement or (ii) USL concludes that such material exceeds the parameters of the
permits applicable to the Landfarm. USL shall notify NESI of any rejection in
writing and shall state the reason therefor. The expiration of such ten-day
period without a rejection or a revocation of a prior acceptance of material
shall constitute "Final Acceptance" of such material.

            6.6.2 REJECTED MATERIAL. Rejected material shall remain at NESI's
risk and expense and shall not be deemed to be incorporated into the Landfarm or
come under the possession, custody, control or ownership of USL. Notwithstanding
the foregoing, to the extent required by federal, state or local law, ordinance,
permit, regulation, directive, code, standard or requirement, or by USL's safety
and/or security rules, practices or procedures, USL may detain any rejected
materials, including the vehicle and/or containers in which such rejected
materials arrived, and shall notify regulatory or other authorities wherever
necessary or appropriate to do so.

            6.6.3 REMOVAL. In the event USL rejects all or any part of a
shipment of material from NESI, after compliance in all material respects with
all regulatory and any other requirements involving detention of such shipment,
upon written request of USL, NESI, unless otherwise directed by a regulatory
agency or other lawful authority, shall promptly remove or cause to be removed
from the Landfarm all of the rejected material at NESI's risk and expense in a
manner consistent with all applicable federal, state and local laws, ordinances,
permits, regulations, directives, codes, standards and requirements. In the
event NESI fails to complete such removal by the fifth business day after the
date of the request by USL, USL, unless otherwise required by law or regulation,
may remove or cause to be removed from the Landfarm any and all of the rejected
material, and may containerize and transport it or cause it to be containerized
and transported to an authorized storage site or returned to NESI at its nearest
location. NESI hereby authorizes USL in such event to contract for such storage
for NESI's account. For its services, USL shall charge and NESI shall pay USL's
cost plus 15%. Any and all material that USL rejects shall remain property and
the responsibility of NESI at NESI's risk and expense.

      6.7 THIRD-PARTY DELIVERIES. USL may follow the procedures set forth in
this Article VI with respect to any third-party generator's vessels or vehicles
containing materials that are delivered

                                      12
<PAGE>
to any Landfarm at the direction of NESI or its Affiliates. In addition, USL may
establish and enforce other policies and procedures relating to the independent
inspection of any such third-party generator's vessels or vehicles before the
material contained in such vessels or vehicles shall be accepted for disposal.

      10.3  INDEMNIFICATION PROCEDURES.

            10.3.1Promptly after receipt by an indemnified party under this
Article X of notice of the commencement of any action or proceeding evidenced by
service of process or other legal pleading, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify in writing the indemnifying party of the commencement thereof; but the
omission so to notify the indemnifying party (i) will not relieve it from any
liability that it may have to any indemnified party under this Article X unless
and to the extent that the indemnifying party has been prejudiced in any
material respect by such omission and (ii) will not relieve the indemnifying
party from any liability that it may have to any indemnified party other than
under this Article X. If any such action or proceeding shall be brought against
any indemnified party and it shall notify the

                                      16
<PAGE>
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, to assume
the defense thereof with counsel reasonably satisfactory to such indemnified
party (who shall not, except with the consent of the indemnified party, be
counsel to the indemnifying party), and, after notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party shall not be liable to such indemnified party
under this Article X for any legal or other expenses subse quently incurred by
such indemnified party in connection with the defense thereof unless the named
parties to such action or proceeding (including any impleaded parties) shall
include both an indemnifying party and an indemnified party and the indemnified
party shall have been advised by counsel that there may be one or more defenses
available to such indemnified party that are different from or additional to
those available to the indemnifying party (in which case, if the indemnified
party notifies the indemnifying party that it wishes to employ separate counsel
at the expense of the indemnifying party (who shall promptly pay all such
expenses as incurred), the indemnifying party shall not have the right to assume
the defense of such action or proceeding on behalf of such indemnified party).

            10.3.2If an indemnifying party, within a reasonable period of time
after notice by the indemnified party of the commencement of any action or
proceeding with respect to which the indemnified party is to make a claim
hereunder, fails to assume the defense thereof, the indemnified party shall have
the right (upon further notice to the indemnifying party) to undertake the
defense, compromise or settlement of such action or proceeding for the account
of the indemnifying party, subject to the right of the indemnifying party to
assume the defense of such action or proceeding at any time prior to settlement,
compromise or final determination thereof. The cost and expense of any such
defense and any judgment in any such action or proceeding shall be borne by the
indemnifying party, and, if paid by the indemnified party, shall be reimbursed
by the indemnifying party within thirty days after receipt of invoice therefor.

            10.3.3Except as otherwise provided in Section 10.3.2, an
indemnifying party shall not be liable for any settlement of any litigation or
proceeding effected without its written consent. An indemnifying party shall
not, without the indemnified party's written consent, settle or com promise any
action or proceeding or consent to entry of any judgment that would impose an
injunction or other equitable relief upon the indemnified party or that does not
include as an unconditional term thereof the release by the claimant or the
plaintiff of such indemnified party from all liability in respect of such action
or proceeding.

                                  ARTICLE XII
                           SUSPENSION OF PERFORMANCE

      12.1 SUSPENSION OF PERFORMANCE BY USL. USL shall have the right to suspend
operations under this Agreement at the Bateman Island Landfarm for any reason.
Upon such suspension, USL shall give NESI written notice of the basis for, and
an estimate of, the length of the suspension.

            12.1.1If USL notifies NESI that it will temporarily suspend
operations at the Bateman Island Landfarm due to litigation, court order or
directive of any governmental body having jurisdiction over the operation of the
Landfarm, or substantial changes to laws or regulations, then NESI shall
continue to make all Payments in Full and on Time as this Agreement requires;
provided, however, that USL shall make available the Bourg and/or Mermentau
Landfarms to accept, in a timely fashion, delivery of that portion of the Annual
Volume that NESI would otherwise deliver to the Bateman Island Landfarm under
Section 3.1.1.a. If USL fails to make available either the Bourg Landfarm or the
Mermentau Landfarm to accept delivery, in a timely fashion, of the NOW that NESI
desires to deliver, up to the Annual Volume (prorated for the period involved),
then NESI shall be excused from payments due each month such failure continues.
Upon the resumption of operations at the Bateman Island Landfarm, NESI may
exercise its option to deliver NOW in accordance with Section 3.1.

            12.1.2If USL notifies NESI that it will temporarily suspend
operations at the Bateman Island Landfarm due to, caused by or resulting from
fire, lightning, explosion, windstorm, hail, smoke, aircraft or vehicles, riot
or civil commotion, sinkhole collapse, volcanic action, falling objects, weight
of snow, ice or sleet, water damage, vandalism, and malicious mischief, flood,
and/or earthquake, including order of civil authority when such order is given
as a direct result of any other cause named in this sentence, then NESI shall be
excused from payments due each month that operations are suspended. Upon the
resumption of operations at the Bateman Island Landfarm, NESI shall resume
payments and may exercise its option to deliver NOW in accordance with Section
3.1.

            12.1.3If USL notifies NESI that it will temporarily suspend
operations at the Bateman Island Landfarm voluntarily for any reason other than
under Section 12.1.1 or 12.1.2 above, NESI is excused from payments due each
month that operations are suspended. Upon the resumption of operations at the
Bateman Island Landfarm, NESI shall resume payments and may exercise its option
to deliver NOW in accordance with Section 3.1.

            d. If operations are temporarily suspended at the Bourg, Bateman
Island and Mermentau Landfarms at once or in reasonably close succession, then
NESI is excused from payments due each month that operations are suspended. Upon
the resumption of operations at any

                                      18
<PAGE>
Landfarm, and provided USL makes any Landfarm available to accept delivery in a
timely fashion, of the NOW that NESI desires to deliver, up to the Annual Volume
(prorated for the period involved), then NESI shall resume payments and may
exercise its option to deliver NOW in accordance with Section 3.1.

            e. Whenever, in accordance with the foregoing provisions of this
Section 12.1, NESI is excused from making payments of a portion of the Disposal
Amount for any month or months, such excuse shall be a permanent excuse, and the
total Disposal Amount for the Contract Year or Contract Years in which such
excuse occurs shall be reduced accordingly.

      12.2 SUSPENSION OF PERFORMANCE BY NESI. NESI has no right to suspend its
performance except as specifically provided elsewhere in this Agreement and any
other suspension or attempt to suspend its obligations shall constitute breach
of this Agreement. Disapproval, instruction or communication by a customer of
NESI, including any request by any NESI customer as to where its waste should be
delivered, in a manner contrary to the terms of this Agreement shall not
constitute force majeure nor provide a basis for suspension of performance.

                                 ARTICLE XIII
                                 MISCELLANEOUS

      13.1 STATUS OF THE PARTIES. Each party hereto is and shall perform this
Agreement as an independent contractor, and as such, shall have and maintain
complete control over all of its employees, agents, and operations. Except as
expressly otherwise provided in this Agreement, neither party nor anyone
employed by it shall be, represent, act, purport to act or be deemed to be the
agent, representative, employee or servant of the other party.

      13.2 NO SET-OFF RIGHTS. The parties hereby agree that neither party shall
have any right to set-off or apply against any sums due under this Agreement any
sums due or amounts otherwise owing pursuant to any other provision of this
Agreement or any other agreement or arrangement between the parties.

      13.3 SUBROGATION; ASSIGNMENT OF RIGHTS. In the event NESI delivers and USL
accepts a delivery of materials (the "Nonconforming Materials") containing
hazardous or dangerous substances in violation of this Agreement and in
violation of NESI's agreement with the third-party generator producing such
materials, NESI agrees that, upon the request of USL, USL shall become fully
subrogated to the rights of NESI against such generator related to the
Nonconforming Materials, and NESI shall (i) assign or take such further action
as is necessary or desirable to transfer to USL any and all rights of action of
NESI against such generator relating to such Nonconforming Materials arising at
law under NESI's agreement with such generator or in equity and (ii) use its
good faith best efforts to assist in the prosecution of any claim brought by USL
against such third-party generator relating to the Nonconforming Materials.

      13.4 BINDING EFFECT; ASSIGNMENT. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns. USL and NESI may assign

                                      19
<PAGE>
their rights, obligations and duties under this Agreement with the written
consent of the other parties to the Agreement, which consent shall not be
unreasonably withheld; provided that the assigning party shall remain primarily
liable for all obligations and duties arising hereunder. Without limiting the
generality of the foregoing, if USL sells the Landfarms and/or related business,
the purchaser shall assume USL's obligations under this Agreement, and NESI
shall retain its obligations under this Agreement.

      13.5  NOTICES.

            13.5.1GENERAL. Except under Section 3.1.1, notices and other

      13.6 OPPORTUNITY TO CURE. In the event that NESI (i) fails to pay USL any
amount required under this Agreement on or before the date such payment is due
and such payment is not excused by Section 12.1 and/or (ii) otherwise fails to
perform under this Agreement, USL shall give notice to NESI of its failure to
perform in accordance with Section 13.5. The notice shall include a description
of the manner in which NESI failed to perform under this Agreement and shall
include the date on which performance was due. NESI shall have fifteen (15)
calendar days from the date notice is deemed validly given to correct or cure
its failure to perform under this Agreement. If NESI fails to do so, then such
failure shall constitute a breach of this Agreement. If NESI receives from USL
notice that NESI has failed to pay USL any amount required, due and not
otherwise excused under this Agreement and NESI fails to correct or cure such
failure within 15 days from the date such notice is given, then such failure
shall be deemed failure to make Payment in Full and on Time and shall constitute
a breach of this Agreement. Failure by USL to act in accordance with this
Section shall not itself constitute a breach of this Agreement nor shall such
failure cause USL to waive or relinquish any right or option provided by any
Section in this Agreement; provided, however, that NESI shall not be deemed to
have breached this Agreement unless and until notice of such alleged breach
shall have been given in accordance with this section, and NESI shall have
failed to cure or correct its failure to perform as specified in such notice.

      13.7 NON-WAIVER. The failure of any party to enforce its rights under any
provision of this Agreement shall not be construed to be a waiver of such
provision. No waiver of any breach of this Agreement shall be held to be a
waiver of any other breach.

      2. NONCOMPETITION. USL hereby agrees, for itself and on behalf of its
Affiliates, that, during the term of this Agreement, except as otherwise
permitted under this Agreement, neither it nor any of its Affiliates will,

continue in force each month that Newpark makes to USL all Payments in Full and
on Time under the NOW Payment Agreement. Any breach and/or failure to make
Payment in Full and on Time under the NOW Payment Agreement shall immediately

      4. MAINTENANCE OF CONFIDENTIALITY. For the term of this Agreement, USL and
its Affiliates shall keep secret and retain in strictest confidence, except for
disclosure to any of its Affiliates, and will not permit any Person other than
its Affiliates to exercise the right, on a nonexclusive basis, to use all
patents, patent applications, copyrights, trademark registrations and
applications therefor, inventions, trade secrets, technical know-how, special
processes, and similar intangibles, parts lists, designs, specifications,
drawings, bills of material, maintenance manuals, warranty service data and
sales literature (collectively, "Intangible Assets") related to the Business,
which Newpark has been granted the right to use, along with USL and its
Affiliates.

      5. PERMITTED ACTIVITIES. Section 2 of this Agreement notwithstanding:

            a. USL and its Affiliates, as passive investors, may own up to 5%
(including ownership by USL and all of its Affiliates) of the equity securities
of any Person (other than Newpark) whose equity securities are publicly traded.
In addition, in connection with their business

                                      3
<PAGE>
described in subparagraph (b) below, USL and its Affiliates shall be permitted
from time to time to acquire interests representing more than 5% of the equity
securities of Persons that derive less than 10% of their revenues from
activities that cause such Persons to be Competitors, provided that USL or its
Affiliates or the Persons who engage in such competitive activities immediately
formulate plans to dispose of those aspects of such businesses that cause such
Persons to be Competitors and actually complete such dispositions within 90 days
after such interests are acquired by USL or one or more of its Affiliates.

            b. Newpark recognizes and acknowledges that USL and its Affiliates
are in the business of the collection, treatment and disposal of numerous
varieties of wastes, including, without limitation, municipal solid wastes,
construction and demolition debris, industrial nonhazardous wastes and special
wastes, such as contaminated soil and sludges. Newpark agrees that this
Agreement relates only to the Collection and Disposal of NOW and the remediation
and closure of oilfield waste pits, including related loading and hauling, in
the Territory, and excludes the Cleaning Business. This Agreement is not
intended to limit or otherwise affect the business of USL except as expressly
set forth herein.

            c. Newpark further recognizes and acknowledges that USL and its
Affiliates from time to time enter into joint venture arrangements with
independent (i.e., non-Affiliate) third parties ("Joint Venture Partners") who
engage in aspects of the Business in the Territory. Without limiting the
applicability of this Agreement to USL and its Affiliates and such joint
ventures, Newpark agrees that the terms of this Agreement shall not apply to
Joint Venture Partners solely as a result of their entering into joint venture
arrangements with USL and its Affiliates with respect to the continuation of
activities in which such Joint Venture Partners were engaged immediately prior
to entering into such joint venture arrangements.

            d. USL and its Affiliates may market, deal in, solicit orders for
and conduct other activity related to: (i) Disposal and Collection at any of the
Landfarms of Excluded NOW; (ii) Collection of NOW within a 200-mile radius of
USL's Zapata, Texas, facility and Disposal of NOW so Collected at such facility;
(iii) Disposal and Collection of NOW contemplated under the NOW Payment
Agreement dated as of September 16, 1998, by and among USL and Newpark
Environmental Services, Inc.; (iv) Disposal and Collection of NOW at USL's
facility in Lacassine, Louisiana; and (v) the Cleaning Business.

            e. USL shall be free to engage in any aspect of the Cleaning
Business.

      6. SEVERABILITY. USL acknowledges that it has carefully read and
considered the provisions of this Agreement and, having done so, agrees that the
restrictions set forth herein (including, but not limited to, the time periods
of restriction and the geographical areas of restriction) are fair and
reasonable and are reasonably required to protect the interests of Newpark and
its stockholders. In the event that, notwithstanding the foregoing, any of the
provisions of this Agreement shall be held to be invalid or unenforceable, the
remaining provisions hereof shall nevertheless continue to be valid and
enforceable, as though the invalid or unenforceable parts had

                                      4
<PAGE>
not been included herein. In the event that any provision of this Agreement
relating to time periods or areas of restriction, or both, shall be declared by
a court of competent jurisdiction to exceed the maximum time periods or areas
(or both) that such court deems reasonable and enforceable, said time periods or
areas of restriction or both shall be deemed to become and thereafter shall be
the maximum time periods and areas which such court deems reasonable and
enforceable.

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

      8. NATURE OF OBLIGATIONS. All covenants and obligations of USL hereunder
shall be binding on USL, its Affiliates and the assigns, successors and legal
representatives of each of them, and shall inure to the benefit of Newpark and
all of its Affiliates that engage in any aspect of the Business in any part of
the Territory.

      9. NOTICES. Any and all notices, demands, requests or other communications
hereunder shall be in writing and shall be deemed duly given when personally

which are referred to in this Agreement by the names with which they are
identified on Schedule I. Sanifill and Campbell were not relieved of any of
their obligations to Newpark under the Contracts and certain other agreements.

            B. Concurrently with the execution of this Agreement, Newpark and
USL are executing a Settlement of Arbitration and Release (the "Release"), a
"NOW Payment Agreement," a "Noncompetition Agreement," and an "Asset Purchase

            C. By this Agreement, the parties intend to clarify the continuing
status of the Contracts after the execution of the Release and the New Deal
Agreements.

            NOW THEREFORE, in consideration of the foregoing and of their mutual

force and effect in accordance with their terms solely with respect to events

in a timely manner. Newpark further covenants and agrees that it shall take all
action, including, without limitation, supplying information necessary for the
determination of quantities of NOW that may be delivered pursuant to the NOW
Payment Agreement, or shall refrain from taking any action, as is necessary or
appropriate, to permit NESI to fully perform all of its obligations under the
NOW Payment Agreement in a timely manner.

                  3.2 UNCONDITIONAL GUARANTEE. Newpark hereby unconditionally
and irrevocably guarantees the performance in full of all obligations of NESI
under the NOW Payment Agreement, with the same force and effect and to the same

rights and obligations thereunder as NESI.

                  3.3 NO SET-OFF; GUARANTY OF PERFORMANCE OR PAYMENT UPON
DEMAND. Newpark shall perform any obligations or pay any amounts due in respect
of the obligations of NESI under the NOW Payment Agreement promptly upon demand
by USL or its Affiliates, without any set-off, defense or deduction for any
claims or counterclaims of any kind, except for any such set-offs, defenses, or
deductions that Newpark could assert if it were a party to the NOW Payment
Agreement having the same rights and obligations thereunder as NESI.

                  3.4 WAIVER OF DILIGENCE, ETC. Newpark hereby waives diligence,
presentment, demand, protest and notice of any kind with respect to this
Guarantee, as well as any requirement that USL or its affiliates exhaust any
rights or take any action against NESI.

                  3.5 WAIVER OF SURETYSHIP DEFENSES. To the extent permitted by
applicable law, Newpark hereby waives any and all legal and equitable defenses
that arise by reason of Newpark's status as a surety for NESI, which defenses
would not be available to Newpark if it were a party to the NOW Payment
Agreement having the same rights and obligations thereunder as NESI.

                  3.6 STATUS. This Section 3 shall remain in full force and
effect to the extent that the NOW Payment Agreement remains in full force and
effect in accordance with its terms and shall terminate when and to the extent
that the NOW Payment Agreement is terminated.

            4. STATUS OF PRIOR GUARANTY. The Prior Guaranty shall remain in full
force and effect to the extent that the Disposal Agreement remains in full force
and effect in accordance with

                                      2

its terms and shall terminate as of the Effective Date to the extent that the
Disposal Agreement is terminated.

            5. GUARANTEE OF ASSET PURCHASE AGREEMENT. Newpark hereby
unconditionally and irrevocably guarantees the performance in full of all
obligations of NESI under the Asset Purchase Agreement, with the same force and
effect and to the same extent as if Newpark were a party to the Asset Purchase
Agreement having the same rights and obligations thereunder as NESI. Newpark
hereby waives diligence, presentment, demand, protest and notice of any kind
with respect to this Guarantee, as well as any requirement that USL or its
affiliates exhaust any rights or take any action against NESI.

            6. STATUS OF LEASE AND SUBLEASES. The Lease and the Subleases
referred to in Schedule I of this Agreement shall remain in full force and
effect for three years beginning July 1, 1998, and then terminate on June 30,
2001. USL shall take all necessary and reasonable measures to ensure that the
Lease and Subleases remain in full force and effect until June 30, 2001.

            7. OTHER AGREEMENTS. All other agreements between or among Newpark
and Sellers, or any of them, whether or not assumed by USL, shall remain in full
force and effect in accordance with their terms. USL shall use commercially
reasonable efforts to enforce for the benefit of Newpark all relevant covenants,
including, but not limited to, noncompetition covenants, made by Sellers in
favor of USL under or in connection with the Sanifill Purchase Agreement.

            8. EFFECT ON SELLERS. Although Sellers are not party to this
Agreement, the parties intend that none of Sellers shall be relieved of any
obligations owed by them to Newpark by reason of the transactions which gave
rise to the Contracts, except to the extent that certain provisions of the
