                               PROSPECTUS SUMMARY

     THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND THE FINANCIAL STATEMENTS AND NOTES THERETO APPEARING ELSEWHERE
IN THIS PROSPECTUS. SINCE THE COMPANY'S INITIAL PUBLIC OFFERING (THE "IPO") IN
AUGUST 1997, THE COMPANY HAS ACQUIRED OR CONTRACTED TO ACQUIRE 20 BUSINESSES
(THE "ACQUISITIONS"), WHICH COLLECTIVELY HAD 1997 PRO FORMA REVENUES OF
APPROXIMATELY $111.8 MILLION. ALL OF THESE ACQUISITIONS HAVE BEEN CONSUMMATED
EXCEPT THE ACQUISITION OF THREE SEPARATE BUSINESSES, UNIVERSAL WASTE AND
TRANSIT, CITY ENVIRONMENTAL, INC., AND NORTHERN A-1 SERVICES, INC. (THE
"PENDING ACQUISITIONS"), WHICH ARE UNDER DEFINITIVE AGREEMENTS. EXCEPT AS
OTHERWISE NOTED HEREIN, ALL INFORMATION IN THIS PROSPECTUS ASSUMES (I) THAT THE
PENDING ACQUISITIONS HAVE BEEN CONSUMMATED, (II) NO EXERCISE OF THE
UNDERWRITERS' OVER-ALLOTMENT OPTION, AND (III) AN OFFERING PRICE OF $25 PER
SHARE OF COMMON STOCK IN THIS OFFERING (THE "ASSUMED OFFERING PRICE"). SEE
"UNDERWRITING."

                                  THE COMPANY

     U S Liquids Inc. (the "Company") is a rapidly growing provider of
integrated liquid waste management services, including collection, processing,
recovery and disposal services. The Company's primary focus of operations is
industrial and commercial wastewater treatment, although the Company also
collects, processes and disposes of oilfield waste. The Company operates 34
processing facilities located in eight states and serves over 20,000 customers.
The services provided by the Company to any particular customer vary depending
on the type of liquid waste generated, local regulations and the treatment
capabilities of local publicly-operated treatment works ("POTWs").

     The Company has adopted an acquisition-based growth strategy and intends to
continue its expansion, generally through (i) acquiring liquid waste processing
facilities; (ii) securing captive waste streams for its facilities by acquiring
collection companies and by entering into long-term contracts directly with
customers or collection companies; and (iii) integrating acquired companies into
the Company's operations to achieve operating efficiencies and economies of
scale. The Company believes that the liquid waste industry is highly fragmented
and that substantial acquisition opportunities exist throughout North America.
Since the Company's initial public offering in August 1997, the Company has
acquired 20 businesses, which collectively had 1997 pro forma revenues of
approximately $111.8 million.

     The Company provides liquid waste management services through a number of
subsidiaries which are organized into two divisions. The Industrial Wastewater
Division collects, processes and disposes of liquid waste (such as industrial
wastewater, grease and grit trap waste, bulk liquids and unsaleable beverages,
and certain hazardous wastes) and recovers saleable by-products (such as fats,
oils, feed proteins, ethanol and solvents) from certain of the waste streams.
Typically, the Company uses a variety of physical, chemical, thermal and
biological techniques to break down the liquid waste into constituent
components. Water extracted from the liquid waste is pretreated and then
discharged into a POTW and solid materials are dried and disposed of in a solid
waste landfill. The Oilfield Waste Division collects, processes and disposes of
waste generated in oil and gas exploration and production. The Company's
Industrial Wastewater Division generated 82.0% of the Company's 1997 pro forma
revenues of $150.0 million and the Oilfield Waste Division generated the
remaining 18.0% of such pro forma revenues.

     The Company believes that as it expands it is likely to gain numerous
competitive advantages relative to smaller operators, including: servicing
multiple customer locations, treating a wide variety of liquid waste streams,
achieving operating efficiencies (including collection route densification and
consolidation, and increased equipment and facility utilization), increased
economies of scale (including access to lower-cost capital, lower insurance
rates and decreased proportional selling, general and administrative expenses),
and adapting to changing regulations.

     According to The McIlvaine Company, the industrial and commercial
wastewater treatment market is highly fragmented with thousands of businesses
generating an estimated $25 billion in revenues in 1995. This market is expected
to grow to over $29 billion in revenues in 2000. The Company believes that this

                                       3
<PAGE>
growth reflects the following trends: (i) municipalities refusing to accept
certain industrial wastewaters due to limited treatment capabilities and a lack
of resources needed to expand or modernize their POTWs, (ii) industrial and
commercial businesses avoiding POTW surcharges by using third parties to process
and dispose of their wastewater, (iii) industrial and commercial businesses
outsourcing their wastewater treatment needs, (iv) continued industrial and
commercial expansion, and (v) increasingly strict regulations governing the
disposal of industrial wastewater and other liquid wastes, as well as more
stringent enforcement of such regulations.

STRATEGY

     The Company's objective is to continue to grow throughout North America by
expanding its services in markets where it can be one of the largest and most
profitable integrated liquid waste management service companies. The Company has
assembled a management team with significant operating and consolidation
experience in the waste management industry. The key elements of the Company's
strategy are:

          EXPAND THROUGH ACQUISITIONS.  The Company intends to continue to
     aggressively pursue acquisitions of liquid waste management companies in
     new geographic areas, while increasing its facility and equipment
     utilization and expanding its market penetration and range of services
     offered in its existing markets through "tuck-in" acquisitions.

          INTERNAL GROWTH.  The Company intends to expand its customer base by
     positioning itself as a multi-city, single source provider of liquid waste
     management services for national and regional generators of liquid waste.
     The Company also plans to expand the capacity and processing capabilities
     of its existing liquid waste facilities, and is seeking to amend its
     permits for certain facilities in order to receive additional liquid waste
     streams.

          OPERATIONAL ENHANCEMENTS.  The Company will seek to enhance the
     operations of its existing facilities and acquired businesses through
     collection route densification and consolidation and increased facility and
     equipment utilization. The Company also expects to realize economies of
     scale, as well as cost savings by consolidating certain administrative
     functions at its corporate offices.

          OPERATE ON DECENTRALIZED BASIS.  The Company intends to continue to
     manage its various businesses on a decentralized basis, with local
     management maintaining responsibility for the day-to-day operations,
     profitability and growth of the business. The Company believes that such a
     decentralized operating structure will allow the Company to capitalize on
     the considerable local and regional market knowledge and customer
     relationships possessed by local management.

                             SUMMARY FINANCIAL DATA

     The historical statement of operations data below sets forth the financial
data of the Company for the year ended December 31, 1997, derived from the
consolidated financial statements audited by Arthur Andersen LLP, which appear
elsewhere in this Prospectus. The historical statement of operations for the
three months ended March 31, 1997 and 1998 and the balance sheet data as of
March 31, 1998 have been derived from the unaudited consolidated financial
statements of the Company. The unaudited consolidated financial statements for
all periods have been prepared on the same basis as the audited consolidated
financial statements and in the opinion of the Company reflect all adjustments,
consisting of normal recurring adjustments, necessary for a fair presentation of
such data. The statement of operations data below present depreciation and
amortization expenses separately from operating expenses and selling, general
and administrative expenses. Depreciation and amortization expenses are included
in the operating and the selling, general and administrative expense captions
set forth in the audited financial statements.

     The unaudited pro forma financial data set forth below present certain
financial information for the Company which gives effect to (i) the Acquisitions
and certain pro forma adjustments to the historical financial statements of the
businesses acquired, including adjusting depreciation and amortization expenses
to reflect purchase price allocations, recording interest expense to reflect
debt issued in connection with the Acquisitions, certain reductions in salaries
and benefits payable to the owners of the businesses acquired which were agreed
to in connection with the Acquisitions and the related income tax effects of
these adjustments, and (ii) the consummation of this offering at the Assumed
Offering Price and the application of the net proceeds therefrom. The pro forma
financial information is not necessarily indicative of results the Company would
have obtained had these events actually then occurred or the Company's future
results and should be read in conjunction with the other financial statements
and notes thereto included elsewhere in this Prospectus. See "Selected
Financial Data."

                                  RISK FACTORS

     THE COMMON STOCK BEING OFFERED HEREBY INVOLVES A SIGNIFICANT DEGREE OF
RISK. IN ADDITION TO THE OTHER INFORMATION SET FORTH IN THIS PROSPECTUS,
PROSPECTIVE PURCHASERS OF THE COMMON STOCK SHOULD CONSIDER CAREFULLY THE
FOLLOWING RISK FACTORS IN EVALUATING AN INVESTMENT IN THE COMPANY. THIS
PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS WITHIN THE MEANING OF SECTION 27A
OF THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND SECTION
21E OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED (THE "EXCHANGE ACT"),
THAT INVOLVE RISKS AND UNCERTAINTIES, SUCH AS STATEMENTS OF THE COMPANY'S
STRATEGIES, PLANS, OBJECTIVES, EXPECTATIONS AND INTENTIONS. THE COMPANY'S ACTUAL
RESULTS COULD DIFFER MATERIALLY FROM THOSE ANTICIPATED IN THESE FORWARD-LOOKING
STATEMENTS AS A RESULT OF ANY NUMBER OF FACTORS, INCLUDING THE RISK FACTORS SET
FORTH BELOW AND ELSEWHERE IN THIS PROSPECTUS. THE CAUTIONARY STATEMENTS MADE IN
THIS PROSPECTUS SHOULD BE READ AS BEING APPLICABLE TO ALL RELATED
FORWARD-LOOKING STATEMENTS WHEREVER THEY APPEAR IN THIS PROSPECTUS.

LIMITED OPERATING HISTORY; ABSENCE OF COMBINED OPERATING HISTORY

     The Company was organized in November 1996 and began active operations in
December 1996. As a result, the Company has very little operating history as an
integrated liquid waste management business to which investors may look to
evaluate the Company's performance. In addition, since its IPO in August 1997,
the Company has completed 20 acquisitions, several of which were accounted for
under the pooling-of-interests method of accounting. There can be no assurance
that the Company will be able to successfully integrate the operations of the
acquired businesses or any subsequently acquired business or to institute the
necessary systems and procedures, including accounting and financial reporting
systems, to manage the entire combined enterprise on a profitable basis. In
addition, there can be no assurance that the Company's management group will be
able to effectively manage the combined entity or to effectively implement the
Company's acquisition program and internal growth strategy. The Pro Forma
Financial Statements of the Company cover periods when the businesses acquired
in the Acquisitions were not under common control or management and may not be
indicative of the Company's future financial or operating results. The inability
of the Company to integrate these acquired businesses successfully would have a
material adverse effect on the Company's business, results of operations and
financial condition, as well as its acquisition program. See
"Business -- Acquisition Program" and "Management."

RISKS RELATED TO THE COMPANY'S ACQUISITION STRATEGY

     The Company intends to grow significantly through the acquisition of
additional liquid waste management businesses. The Company expects to face
competition for acquisition candidates, which may limit the number of
acquisition opportunities and may lead to higher acquisition prices. There can
be no assurance that the Company will be able to identify, acquire or manage
additional businesses profitably or to integrate successfully any acquired
businesses into the Company without substantial or material unanticipated costs,
delays or other operational or financial problems. Businesses acquired by the
Company may have liabilities that the Company does not discover or may be unable
to discover during its pre-acquisition investigations, including liabilities
arising from environmental contamination or non-compliance by prior owners with
environmental laws or regulatory requirements, and for which the Company, as a
successor owner or operator, may be responsible. Certain environmental
liabilities, even if not expressly assumed by the Company, may nonetheless be
imposed on the Company under certain legal principles of successor liability,
including those under the Comprehensive Environmental Response Compensation and
Liability Act, as amended ("CERCLA"). Three of the businesses acquired in the
Acquisitions process hazardous substances at their facilities. The Company may
be required under federal, state or local law to investigate and remediate any
contamination that may have resulted from the processing of any hazardous
substances by either of these businesses. Any indemnitees or warranties, due to
their limited scope, amount, duration, the financial limitations of the
indemnitor or warrantor, or other reasons, may not fully cover such liabilities.
Further, acquisitions involve a number of other special risks, including failure
of the acquired business to achieve expected results, diversion of management's
attention, failure to retain key personnel of the acquired business and risks
associated with unanticipated events, all of which could have a material

                                       7
<PAGE>
adverse effect on the Company's business, results of operations and financial
condition. In addition, if the Company is not able to successfully integrate the
operations of one or more of its acquired businesses, the benefits expected to
be derived by the Company from consolidating certain overhead functions such as
cash management, human resources, finance and insurance will not be realized.
The Company currently has no binding agreements to make any acquisitions. See
"Business -- Acquisition Program" and "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Overview."

MANAGEMENT OF GROWTH

     To manage its growth effectively, the Company will be required to continue
to implement and improve its operational, financial and management information
systems and controls, and to train, motivate and manage its employees. The
Company intends to continually review and upgrade its management information
systems, as well as hire additional management and other personnel in order to
maintain the adequacy of its operational, financial and management controls. The
Company's failure to manage its growth effectively could have a material adverse
effect on the Company's business, results of operations and financial condition.
See "Management."

RISKS RELATED TO ACQUISITION FINANCING

     The timing, size and success of the Company's future acquisition efforts
and the associated capital requirements cannot be readily predicted at this
time. The Company currently intends to finance future acquisitions by using a
combination of Common Stock and cash. In the event shares of Common Stock are
issued in connection with future acquisitions or earn-out provisions of
completed acquisitions, purchasers of Common Stock in this offering may
experience dilution in the net tangible book value of their stock. If the Common
Stock does not maintain a sufficient market value, or potential acquisition
candidates are otherwise unwilling to accept Common Stock as part of the
consideration for the sale of their businesses, the Company may be required to
use more of its cash resources, if available, or incur indebtedness in order to
continue its acquisition program. The Company has a $100.0 million credit
facility (the "Credit Facility") with a group of banks under which the Company
may borrow to fund acquisitions and working capital requirements; however, under
the Credit Facility the banks' consent is required in order for the Company to
consummate certain acquisitions or incur indebtedness (including, without
limitation, debt assumed in connection with acquisitions). After the
consummation of this offering and the application of the net proceeds therefrom,
the Company anticipates that it will have no borrowings outstanding under the
Credit Facility. If the Company does not have sufficient cash resources, its
growth could be limited unless it is able to obtain additional capital through
debt or equity financings. There can be no assurance that the Company will be
able to obtain such financing when required or that such financing will be
available on terms and conditions reasonably acceptable to the Company. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."

RISKS RELATED TO OPERATING AND INTERNAL GROWTH STRATEGY

     Key elements of the Company's strategy are to improve the profitability and
increase the revenues of its existing operations and any subsequently acquired
businesses. The Company intends to improve the profitability of its existing
operations and any subsequently acquired businesses by various means, including
achieving operating efficiencies and economies of scale. The Company's ability
to increase the revenues of its existing operations and any subsequently
acquired businesses will be affected by various factors, including the demand
for liquid waste collection, processing and disposal services, as well as the
demand for by-products recovered by the Company from certain liquid waste
streams, and the Company's ability to expand the range of services offered to
customers, develop national and regional accounts for its liquid waste
management services and other marketing programs. Many of these factors are
beyond the Company's control, and there can be no assurance that the Company's
operating and internal growth strategies will be successful or that the Company
will be able to generate cash flow adequate for its operations and to support
internal growth. See "Business -- Strategy."

                                       8
<PAGE>
COMPETITION

     The liquid waste industry is highly fragmented and very competitive. The
Company competes with other liquid waste processing facilities and alternative
methods of disposal of certain waste streams provided by area landfills and
injection wells, as well as the alternative of illegal disposal. In addition,
competitive products and services have been and will continue to be successfully
developed and marketed by others. Furthermore, future technological change and
innovation may result in a reduction in the amount of liquid waste being
generated or alternative methods of processing and/or disposal being developed.
The Company's inability to procure sufficient quantities of liquid waste would
have a material adverse effect on the Company's business, results of operations
and financial condition. The market for the various by-products recovered by the
Company for sale to third parties is also very competitive and is served by
several large companies and a number of smaller, owner-operated companies. With
respect to its oilfield waste operations, the Company must compete with
alternative methods of off-site disposal of oilfield waste. The Company also
faces competition from customers who seek to enhance and develop their own
methods of disposal instead of using the services of third parties such as the
Company. Future technological change and innovation may increase the amount of
internal oilfield waste processing and disposal as well as the number of
competitors in this market. Increased use of internal processing and disposal
methods and other competitive factors could have a material adverse effect on
the Company's business, results of operations and financial condition. In
addition, until August 2001, the Company is prohibited from engaging in certain
activities relating to the collection, transportation or disposal of oilfield
waste generated in the Gulf of Mexico and certain surrounding states and other
related businesses. See " -- Dependence on Newpark for Offshore-Generated
Oilfield Waste; Covenant Not to Compete; and Obligation to Treat Oilfield Waste
Received from Newpark at Below-Market Prices," "Business -- Operations and
Services Provided" and "Certain Transactions -- Campbell Wells Acquisition."

     Competitors of the Company may be better capitalized, have greater name
recognition or be able to provide services or products at a lower cost. In
addition, as the liquid waste market matures, competition can be expected to
increase. As a result of these competitive factors, there can be no assurance
that the Company's growth strategy will be successful or that the Company will
be able to generate cash flow adequate for its operations and to support future
acquisitions and internal growth. See "Business -- Competition."

FAILURE TO COMPLY WITH GOVERNMENTAL REGULATIONS

     The Company's operations are subject to numerous and continually evolving
federal, state and local laws, regulations and policies that govern
environmental protection, zoning and other matters, including the Clean Water
Act, the Resource Conservation and Recovery Act of 1976, as amended ("RCRA")
and the Clean Air Act. If existing regulatory requirements change, the Company
may, among other things, be required to make significant unanticipated capital
and operating expenditures. Although the Company believes that it is presently
in material compliance with applicable laws and regulations, there can be no
assurance that it will be deemed to be in compliance in the future. Governmental
authorities may seek to impose fines and penalties on the Company or to revoke
or deny the issuance or renewal of operating permits for failure to comply with
applicable laws and regulations. Under such circumstances, the Company might be
required to curtail or cease operations or conduct site remediation until a
particular problem is remedied, which could have a material adverse effect on
the Company's business, results of operations and financial condition. In
addition, if the Company's operations resulted in the release of hazardous
substances, the Company could incur liability under CERCLA. See
"Business -- Regulatory Background."

IMPACT OF FAILURE TO OBTAIN OR MAINTAIN NECESSARY GOVERNMENTAL APPROVALS

     The Company operates in a highly regulated environment and the facilities
at which the Company processes liquid waste are required to have permits and
approvals from federal, state and local governments. Any of such permits or
approvals or applications may be subject to denial, revocation or modification
under various circumstances. In addition, in the event new environmental
legislation or regulations are enacted or existing legislation or regulations
are amended or are enforced differently, the Company may be required to

                                       9
<PAGE>
obtain additional operating permits or approvals. The process of obtaining a
required permit or approval may be lengthy and expensive and the issuance of
such permits or the obtaining of such approval may be subject to public
opposition. There can be no assurance that the Company will be successful in
obtaining or maintaining all required permits and approvals. Any such failure
could have a material adverse effect on the Company's business, results of
operations and financial condition.

POTENTIAL ENVIRONMENTAL LIABILITY; INSUFFICIENCY OF INSURANCE

     The Company processes and disposes of various types of hazardous and
nonhazardous wastes at its facilities. There may be various adverse consequences
to the Company in the event that a facility owned or operated by the Company
(including any acquired business) causes environmental damage, in the event that
waste transported by the Company causes environmental damage at another site, in
the event the Company fails to comply with applicable environmental and land use
laws and regulations or the terms of a permit or outstanding consent order or in
the event a facility owned or operated by the Company or the soil or groundwater
thereunder is or becomes contaminated. These adverse consequences may include
the imposition of substantial monetary penalties on the Company, the issuance of
an order requiring the curtailment or termination of the operations involved or
affected, the revocation or denial of permits or other approvals necessary for
continued operation or expansion of a facility, the imposition of liability on
the Company with respect of any environmental damage (including groundwater or
soil contamination) at its facilities or that its facilities caused to adjacent
landowners or others or environmental damage at another site associated with
waste transported by the Company, the imposition of liability on the Company
under CERCLA or under comparable state laws, and criminal liability for the
Company or its officers. In addition, citizens' groups, adjacent landowners or
governmental entities could oppose the issuance of a permit or approval to the
Company or allege violations of the permits pursuant to which the Company
operates or laws or regulations to which the Company is subject. Any of the
foregoing could have a material adverse effect on the Company's business,
results of operations and financial condition. CERCLA and comparable state laws
impose retroactive strict joint and several liability on various parties that
are, or have been, associated with a site at which there has been, or is
threatened, a release of any hazardous substance (as defined by CERCLA) into the
environment. Liability under RCRA, CERCLA and comparable state laws may include
responsibility for costs of site investigations, site clean up, site monitoring,
natural resources damages and property damages. Liabilities under RCRA, CERCLA
and comparable state laws can be very substantial and, if imposed upon the
Company, could have a material adverse effect on the Company's business, results
of operations and financial condition. See "Business -- Regulatory
Background."

     The National Emission Standards for Hazardous Air Pollutants ("NESHAPs")
regulate the collection, packaging, transportation and disposal of
asbestos-containing material. NESHAPs regulate visible emissions of asbestos
fibers to outside air and require emissions controls and appropriate work
practices. Asbestos is listed as a hazardous substance under CERCLA. Certain
states have classified asbestos as hazardous waste and require appropriate
handling and disposal practices. One of the businesses recently acquired by the
Company transports and disposes of asbestos-containing materials. There can be
no assurance that the Company will not face claims resulting from environmental
liabilities relating to these and other materials in its waste management
operations.

     During the ordinary course of its operations, the Company has from time to
time received, and expects that it may in the future receive, citations or
notices from governmental authorities that its operations are not in compliance
with its permits or certain applicable environmental or land use laws and
regulations. The Company generally seeks to work with the authorities to resolve
the issues raised by such citations or notices. There can be no assurance,
however, that the Company will always be successful in this regard, and the
failure to resolve a significant issue could result in one or more of the
adverse consequences to the Company described above.

     While the Company maintains liability insurance, the insurance is subject
to coverage limits and certain policies exclude coverage for damages resulting
from environmental contamination. Although there are currently numerous sources
from which such coverage may be obtained, there can be no assurance that
insurance will continue to be available to the Company on commercially
reasonable terms, that the possible

                                       10
<PAGE>
types of liabilities that may be incurred by the Company will be covered by its
insurance, that the Company's insurance carriers will be able to meet their
obligations under the policies or that the dollar amount of such liabilities
will not exceed the Company's policy limits. Even a partially uninsured claim,
if successful and of significant magnitude, could have a material adverse effect
on the Company's business, results of operations and financial condition.

POTENTIAL IMPACT OF STATE OF LOUISIANA EXAMINATIONS OF THE OILFIELD WASTE
DISPOSAL INDUSTRY

     In 1997, after an unsuccessful attempt was made in the Louisiana
legislature to require the Company's Bourg, Louisiana landfarm to relocate or
close, the Governor of Louisiana directed certain state agencies to examine the
operations at the Bourg landfarm and to review generally Louisiana's rules and
regulations regarding the processing and disposal of oilfield waste. As a result
of this mandate, the Louisiana Department of National Resources has adopted
emergency rules that will, among other things, require (i) generators of
oilfield waste to conduct additional tests on oilfield waste to be disposed of
off-site, and (ii) all oilfield waste disposal facilities located in Louisiana
to conduct additional tests on oilfield waste accepted for processing and/or
disposal. These emergency rules went into effect on May 1, 1998 and will
continue for 120 days. Results of the testing conducted by the disposal
facilities and the generators of the oilfield waste will be evaluated by the
Department of Natural Resources to determine if there are any constituents
present in the oilfield waste in high enough concentrations to pose a risk to
human health or the environment and, if so, whether any modifications to the
Department's rules governing the processing and/or disposal of oilfield waste
are warranted. New regulations or changes in applicable regulations resulting
from the implementation of these emergency rules could have a material adverse
effect on the Company's business, results of operations and financial condition.

DEPENDENCE UPON OILFIELD WASTE EXEMPTION UNDER RCRA AND OTHER ENVIRONMENTAL
REGULATIONS

     Oilfield waste is currently exempt from the requirements of RCRA, which is
the principal federal statute governing the handling and disposal of waste. In
recent years, proposals have been made to rescind or modify this exemption. The
repeal or modification of the exemption covering oilfield waste or modification
of applicable regulations or interpretations regarding the processing and/or
disposal of oilfield waste would require the Company to alter its method of
processing and disposing of oilfield waste. Such repeal or modification could
have a material adverse effect on the Company's business, results of operations
and financial condition. Each of the Company's operations is also dependent to
varying degrees on the existence and enforcement of local, state and federal
environmental regulations. Any repeal or relaxation of such regulations, or a
failure of governmental authorities to enforce such regulations, could result in
decreased demand for the Company's services and, therefore, could have a
material adverse effect on the Company's business, results of operations and
financial condition. The Company's operations may also be adversely affected by
new regulations or changes in other applicable regulations. See "Business --
Regulatory Background."

DEPENDENCE ON OIL AND GAS INDUSTRY

     Demand for the Company's oilfield waste processing and disposal services
depends in large part upon the level of exploration for and production of oil
and gas, particularly in the Gulf Coast region. This demand, in turn, depends
on, among other things, oil and gas prices, expectations about future prices,
the cost of exploring for, producing and delivering oil and gas, the discovery
rate of new oil and gas reserves and the ability of oil and gas companies to
raise capital. Prices for oil and gas historically have been extremely volatile
and have reacted to changes in the supply of and demand for oil and natural gas,
domestic and worldwide economic conditions and political instability in
oil-producing countries. No assurance can be given that current levels of oil
and gas activities will be maintained or that the demand for the Company's
oilfield waste services will reflect the level of such activities. Prices for
oil and natural gas are expected to continue to be volatile and affect demand
for the Company's oilfield waste services. A material decline in oil or natural
gas prices or exploration activities could have a material adverse effect on the
demand for the Company's oilfield waste services and, therefore, the Company's
business, results of operations and financial condition.

COMPETE; AND OBLIGATION TO TREAT OILFIELD WASTE RECEIVED FROM NEWPARK AT
BELOW-MARKET PRICES

     In December 1996, the Company acquired five oilfield waste landfarms and
landfills from Campbell Wells, L.P. and Campbell Wells Norm, L.P. (collectively
"Campbell Wells") and Sanifill, each of which is now a wholly-owned subsidiary
of USA Waste. In connection with this acquisition (the "Campbell Wells
Acquisition"), the Company acquired a disposal agreement (the "Disposal
Agreement") and certain related agreements with Newpark Resources, Inc., a
public company located in New Orleans ("Newpark"), that obligate Newpark to
deliver to the Company, in each of the next 23 years, oilfield waste for
treatment and disposal at certain of the Company's Louisiana landfarms.
Specifically, until June 30, 2021, Newpark is obligated to deliver to the
Company for processing and disposal the lesser of (i) one-third of the barrels
of oilfield waste that Newpark receives for processing and disposal in
Louisiana, Texas, Mississippi, Alabama and the Gulf of Mexico (the
"Territory") and (ii) 1,850,000 barrels of oilfield waste, in each case
excluding saltwater. In return, prior to August 2001, the Company is obligated
not to engage, directly or indirectly, in the collection, transfer,
transportation, treatment or disposal of oilfield waste generated in a marine
environment or transported in marine vessels or the site remediation and closure
business in the Territory. As a result of these contractual arrangements with
Newpark, the Company's Oilfield Waste Division is dependent upon Newpark's
ability to maintain its share of the oilfield waste disposal market in the
Territory. There can be no assurance that Newpark will be able to maintain its
share of the oilfield waste disposal market in the Territory, and a significant
decline in Newpark's market share could have a material adverse effect on the
Company's business, results of operations and financial condition. In addition,
these contractual arrangements limit the ability of the Company to expand its
offshore oilfield waste operations in the Territory through acquisitions or
otherwise.

     The Disposal Agreement also governs the price to be paid by Newpark to the
Company for delivered oilfield waste. This contractual price is lower than the
price that the Company could obtain in the open market, and the Company expects
such price disparity to persist for the duration of the Disposal Agreement. For
the year ended December 31, 1997, pro forma revenues of approximately $27.0
million, or approximately 18.0% of the Company's total pro forma revenues, were
derived from the processing and disposal of oilfield waste, of which amount
approximately $7.9 million, or approximately 5.3% of the Company's total pro
forma revenues, was derived from the processing and disposal of oilfield waste
received from Newpark. See "Business -- Operations and Services Provided" and
"Certain Transactions -- Campbell Wells Acquisition."

RELIANCE ON KEY PERSONNEL

     The Company is highly dependent on its executive officers and senior
management, and the Company likely will depend on the senior management of any
significant business it acquires in the future. The loss of any of its current
executive officers or key employees or any member of senior management of any
subsequently acquired business could have a material adverse effect on the
Company's business, results of operations and financial condition. In addition,
debt outstanding under the Credit Facility may be accelerated at the option of
the lenders in the event that, among other things, Michael P. Lawlor, W. Gregory
Orr or Earl J. Blackwell ceases to serve as an executive officer of the Company
and is not replaced within 60 days by an individual reasonably satisfactory to
the lenders. The Company does not maintain key man life insurance on any of its
executive officers or key employees.

LACK OF DIVIDENDS

     The Company has not paid dividends on its Common Stock and does not
anticipate paying dividends in the foreseeable future. The Company intends to
retain future earnings, if any, to finance the expansion of its operations and
for general corporate purposes, including future acquisitions. In addition, the
Credit Facility prohibits the Company from paying dividends on its capital
stock. See "Dividend Policy."

POTENTIAL ANTI-TAKEOVER EFFECT OF CERTAIN CHARTER PROVISIONS

     The Company's Certificate of Incorporation, as amended (the "Certificate
of Incorporation"), provides for a Board of Directors with staggered terms,
which may discourage or prevent certain types of transactions involving an
actual or potential change in control of the Company, including transactions in
which selling stockholders may otherwise receive a premium for their shares over
then current market prices. In addition, pursuant to the Certificate of
Incorporation, the Board of Directors has been authorized to approve the
issuance of shares of currently undesignated preferred stock, to determine the
price, powers, preferences and rights and the qualifications, limitations or
restrictions granted to or imposed on any unissued series of such preferred
stock, and to fix the number of shares constituting any such series and the
designation of such series, without any vote or future action by the
stockholders. The preferred stock could be issued with voting, liquidation,
dividend and other rights superior to the rights of the Common Stock. See
"Description of Securities -- Preferred Stock."

                                USE OF PROCEEDS

     The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby are estimated to be $87.4 million ($100.6 million if the
Underwriters' over-allotment option is exercised in full), after deducting
underwriting discounts and commissions and estimated offering expenses. The
Company intends to apply the net proceeds of the offering against the
outstanding balance of the Credit Facility, the vast majority of which
indebtedness was incurred in connection with acquisitions previously consummated
by the Company. See "Business -- Acquisitions." The Credit Facility expires on
April 10, 2001 and amounts currently outstanding thereunder bear interest at
approximately 7.9%, which rate is anticipated to decrease pursuant to the terms
of the Credit Facility to approximately 6.9% after the consummation of this
offering. Pending application of the net proceeds as described herein, the
Company intends to invest the net proceeds in short-term, interest bearing
investments.

                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY

     The Common Stock has been listed on AMEX since August 20, 1997. The trading
symbol for the Common Stock is "USL." The reported last sale price of the
Common Stock as reported on AMEX on May 5, 1998 was $25. The following table
sets forth, for the periods indicated, the high and low sales prices for the
Common Stock as reported on AMEX.

                            SELECTED FINANCIAL DATA

     The historical statement of operations for the years ended December 31,
1995, 1996 and 1997 and the balance sheet data as of December 31, 1996 and 1997
have been derived from the consolidated financial statements audited by Arthur
Andersen LLP, which appear elsewhere in this Prospectus. The historical
statement of operations data for the year ended December 31, 1994 have been
derived from the consolidated financial statements audited by Arthur Andersen
LLP, which do not appear elsewhere in this Prospectus. The historical statement
of operations for the year ended December 31, 1993, and for the three month
periods ended March 31, 1997 and 1998 and the balance sheet data as of March 31,
1998 have been derived from the unaudited consolidated financial statements of
the Company. The unaudited consolidated financial statements for all periods
have been prepared on the same basis as the audited consolidated financial
statements and in the opinion of the Company reflect all adjustments, consisting
of normal recurring adjustments, necessary for a fair presentation of such data.
The statement of operations data below present depreciation and amortization
expenses separately from operating expenses and selling, general and
administrative expenses. Depreciation and amortization expenses are included in
the operating and the selling, general and administrative expense captions set
forth in the audited financial statements.

     The unaudited pro forma financial data set forth below present certain
financial information for the Company which gives effect to (i) the Acquisitions
and certain pro forma adjustments to the historical financial statements of the
businesses acquired, including adjusting depreciation and amortization expenses
to reflect purchase price allocations, recording interest expense to reflect
debt issued in connection with the Acquisitions, certain reductions in salaries
and benefits payable to the owners of the businesses acquired which were agreed
to in connection with the Acquisitions and the related income tax effects of
these adjustments, and (ii) the consummation of this offering at the Assumed
Offering Price and the application of the net proceeds therefrom. The pro forma
financial information is not necessarily indicative of results the Company would
have obtained had these events actually then occurred or the Company's future
results and should be read in conjunction with the other financial statements
and notes thereto included elsewhere in this Prospectus. See the unaudited Pro
Forma Financial Statements and the notes thereto included elsewhere in this
Prospectus.

    a measure of cash flow, operating results or liquidity, as determined in
    accordance with generally accepted accounting principles, and differs from
    net cash provided by operating activities as determined under generally
    accepted accounting principles in that EBITDA excludes interest expense and
    does not reflect the effects of changes in working capital or deferred tax

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

     THE FOLLOWING DISCUSSION SHOULD BE READ IN CONJUNCTION WITH THE COMPANY'S
CONSOLIDATED FINANCIAL STATEMENTS AND THE RELATED NOTES THERETO, THE PRO FORMA
FINANCIAL STATEMENTS AND THE RELATED NOTES THERETO AND THE OTHER FINANCIAL
INFORMATION APPEARING ELSEWHERE IN THIS PROSPECTUS.

OVERVIEW

     The Company collects, processes, recovers and disposes of liquid waste
through a number of subsidiaries that are organized into two divisions. The
Industrial Wastewater Division collects, processes and disposes of liquid waste
and whenever feasible recovers saleable by-products from these waste streams.
The Company formed its Industrial Wastewater Division when it acquired two
companies in June 1997 in transactions that were accounted for under the
pooling-of-interests method of accounting. The Oilfield Waste Division processes
and disposes of waste generated in oil and gas exploration and production. It
was formed in December 1996 when the Company purchased its Louisiana and Texas
landfarms from Sanifill, a wholly-owned subsidiary of USA Waste. Since the
Company's IPO in August 1997, the Industrial Wastewater Division has acquired 19
businesses and the Oilfield Waste Division has acquired one business.

     Due to the number of acquisitions completed by the Company during the
fourth quarter of 1997 and the first five months of 1998, management's
discussion addresses both historical and pro forma results of operations and
financial condition. The pro forma discussion addresses the results of
operations of the Company for the quarters ended March 31, 1997 and 1998 and the
year ended December 31, 1997, with certain pro forma adjustments as described in
the notes to the Pro Forma Financial Statements. The Pro Forma Financial
Statements (i) assume that the Acquisitions were each completed on January 1,
1997, (ii) include certain adjustments to the historical financial statements of
the businesses acquired, including adjusting depreciation and amortization
expenses to reflect purchase price allocations, recording interest expense to
reflect debt issued in connection with the Acquisitions, certain reductions in
salaries and benefits payable to the owners of the businesses acquired which
were agreed to in connection with the Acquisitions and the related income tax
effects of these adjustments, and (iii) are adjusted for the consummation of
this offering at the Assumed Offering Price and the application of the net
proceeds therefrom as if these events occurred on January 1, 1997. The pro forma
results of operations are not necessarily indicative of the results the Company
would have obtained had the acquired businesses been acquired on that date or of
the Company's future results. The historical discussion addresses the actual
results of operations and financial condition of the Company as shown in its
Consolidated Financial Statements for the quarters ended March 31, 1997 and 1998
and the years ended December 31, 1995, 1996 and 1997. Such statements reflect,
for all periods presented, the historical results of operations of businesses
acquired by the Company in transactions that were accounted for under the
pooling-of-interests method of accounting and the results of operations of other
acquired businesses from their dates of acquisition.

     The Industrial Wastewater Division generated $123.0 million, or 82.0%, of
the Company's 1997 pro forma revenues. This Division derives revenues from two
principal sources: tipping and collection fees received for processing and
disposing of waste and revenue obtained from the sale of by-products, including
fats, oils, feed proteins, industrial and fuel grade ethanol, solvents,
aluminum, glass, plastic and cardboard recovered from waste streams. Some of the
Company's by-product sales involve the brokering of industrial and fuel grade
ethanol produced by third parties in order to meet its customers' volume and
quality requirements. Tipping and collection fees charged to customers vary per
gallon by waste stream according to the constituents of the waste, expenses
associated with processing the waste and competitive factors. By-products are
commodities and their prices fluctuate based on market conditions. The Company
anticipates that revenues from tipping and collection fees, which have higher
margins than by-product sales, will increase at a faster rate than revenues from
sales of by-products and brokering of ethanol. The Company anticipates that the
Industrial Wastewater Division will represent a growing share of the Company's
business because of its projected internal growth and future acquisitions.

                                       18
<PAGE>
     The Oilfield Waste Division generated $27.0 million, or 18.0%, of the
Company's 1997 pro forma revenues. This Division derives revenues from fees
charged to customers for processing and disposing of oil and gas exploration and
production waste. These fees are based on the composition of the waste and
currently range from $0.40 per barrel for saltwater to $6.75 to $10.75 per
barrel for oil-based drilling fluids, depending upon the makeup of the waste.
Accordingly, the Company believes that total revenues are a better indicator of
performance than is the average fee charged. When waste is unloaded at a given
site, the Company recognizes the related revenue and records a reserve for the
estimated amount of expenses to be incurred to process the waste in order to
match revenues with their related costs. As processing occurs, generally over
nine to twelve months, the reserve is depleted as expenses are incurred. The
Company's operating margins in the Oilfield Waste Division are typically higher
than in the Industrial Wastewater Division.

     In connection with the Campbell Wells Acquisition, the Company acquired a
long-term disposal agreement (the "Disposal Agreement") with Newpark for the
processing and disposal of oilfield waste generated offshore in the Gulf Coast
region. During the twelve month period ending December 31, 1997, Newpark
delivered approximately 1,430,000 barrels of oilfield waste, excluding
saltwater, to the Company's landfarms. These deliveries accounted for
approximately $7.9 million, or 5.3%, of the Company's 1997 pro forma revenues.
The price paid by Newpark under the Disposal Agreement is currently $5.50 per
barrel, adjusted semi-annually beginning June 30, 1998, with a price floor of
$5.50 per barrel. Although the contract price is lower than the current market
price for comparable waste, Newpark's delivery obligations under the Disposal
Agreement allow the Company to eliminate virtually all marketing and transfer
expenses on waste delivered under the Disposal Agreement and, consequently, the
Company believes that operating margins on waste volume from Newpark and other
customers are comparable. The Company expects a disparity between the contract
price and market price to continue for the duration of the Disposal Agreement.
While there is no absolute floor on the minimum delivery requirements under the
Disposal Agreement, Newpark is contractually obligated to deliver on an annual
basis to the Company one-third of the barrels of oilfield waste (excluding
saltwater) that Newpark receives for processing and disposal in Louisiana,
Texas, Mississippi, Alabama and the Gulf of Mexico; however, in no event is
Newpark obligated to deliver more than 1,850,000 barrels per contract year. See
"Certain Transactions -- Campbell Wells Acquisition."

     Operating expenses include compensation and overhead related to operations
workers, supplies and other raw materials, transportation charges, disposal fees
paid to third parties, real estate lease payments and energy and insurance costs
applicable to waste processing and disposal operations.

     Selling, general and administrative expenses include management, clerical
and administrative compensation and overhead relating to the Company's corporate
offices and each of its operating sites, as well as professional services and
costs.

     Depreciation and amortization expenses relate to the Company's landfarms
and other depreciable or amortizable assets. Landfarms, which constitute
approximately 38% of the Company's pro forma net property, plant and equipment,
are amortized over 25 years. Other depreciable or amortizable assets are
expensed over periods ranging from three to 40 years. Amortization expenses
relating to acquisitions have not been significant in the past, but will
increase as a result of amortization of goodwill recorded in connection with the
Acquisitions and future acquisitions.

RESULTS OF OPERATIONS

  PRO FORMA AS ADJUSTED RESULTS FOR THE QUARTERS ENDED MARCH 31, 1998 AND 1997

     REVENUES.  Pro forma revenues for the quarter ended March 31, 1998
increased $7.2 million, or 20.8%, from $34.5 million for the quarter ended March
31, 1997 to $41.7 million for the quarter ended March 31, 1998. The Industrial
Wastewater Division contributed $28.9 million, or 83.8%, of first quarter 1997
pro forma revenues and $33.8 million, or 81.1%, of first quarter 1998 pro forma
revenues. Tipping and collection fees generated $17.4 million, or 60.3%, and
$24.0 million, or 71.0%, of the Industrial Wastewater Division's pro forma
revenues for the first quarters of 1997 and 1998, respectively. By-product

                                       19
<PAGE>
sales generated the remaining $11.5 million, or 39.7%, and $9.8 million, or
29.0%, of the Industrial Wastewater Division's pro forma revenues for the first
quarters of 1997 and 1998, respectively. Brokered sales of ethanol included in
by-product sales were $6.3 million and $4.3 million for the first quarters of
1997 and 1998, respectively. The Oilfield Waste Division contributed $5.6
million, or 16.2%, of first quarter 1997 pro forma revenues and $7.9 million, or
18.9%, of first quarter 1998 pro forma revenues.

     Pro forma revenues of the Industrial Wastewater Division increased $4.9
million, or 17.0%, from $28.9 million for the quarter ended March 31, 1997 to
$33.8 million for the quarter ended March 31, 1998. This increase was
attributable to additional volumes of waste processed and an increase in the
average tipping fee, which was partially offset by a decrease in by-product
sales resulting primarily from lower market prices for ethanol. The Oilfield
Waste Division's pro forma revenues increased $2.3 million, or 41.1%, from $5.6
million for the quarter ended March 31, 1997 to $7.9 million for the quarter
ended March 31, 1998 due to additional revenues resulting from a nonrecurring
remediation project in Michigan, an increase in the volume of waste processed
resulting from increased drilling activity in the Gulf Coast region and an
increase in tipping fee rates which became effective in the third quarter of
1997.

     OPERATING EXPENSES.  Pro forma operating expenses increased $3.3 million,
or 13.6%, from $24.4 million for the quarter ended March 31, 1997 to $27.7
million for the quarter ended March 31, 1998. As a percentage of pro forma
revenues, pro forma operating expenses decreased from 70.8% for first quarter
1997 to 66.5% for first quarter 1998. This improvement was due primarily to an
increase in tipping and collection revenues, which have higher margins than
by-product sales, in the 1998 period, as well as increased efficiencies
resulting from higher volumes and operational enhancements.

     DEPRECIATION AND AMORTIZATION.  Pro forma depreciation and amortization
expenses increased $687,000, or 36.9%, from $1.9 million for the quarter ended
March 31, 1997 to $2.6 million for the quarter ended March 31, 1998, primarily
as a result of an increase in capital expenditures. As a percentage of pro forma
revenues, pro forma depreciation and amortization expenses increased from 5.4%
in first quarter 1997 to 6.1% in first quarter 1998.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Pro forma selling, general
and administrative expenses increased $1.2 million, or 34.8%, from $3.5 million
for the quarter ended March 31, 1997 to $4.7 million for the quarter ended March
31, 1998. As a percentage of pro forma revenues, pro forma selling, general and
administrative expenses increased from 10.1% for the first quarter of 1997 to
11.3% for the first quarter of 1998. The increase in such expenses was primarily
due to higher personnel costs and professional fees associated with being a
public company and the establishment of the Company's corporate offices in
Houston in May of 1997.

     INTEREST AND OTHER EXPENSES.  Pro forma net interest and other expenses
decreased by $243,000, or 45.2%, from $538,000 for the quarter ended March 31,
1997 to $295,000 for the quarter ended March 31, 1998. This decrease was
attributable to the use of free cash from operations to reduce debt.

     INCOME TAXES.  The pro forma provision for income taxes increased by
$906,000, or 52.8%, from $1.7 million for the quarter ended March 31, 1997 to
$2.6 million for the quarter ended March 31, 1998 as a result of increased
taxable income. The assumed effective tax rate for both periods was 41.0%.

PRO FORMA AS ADJUSTED RESULTS FOR THE YEAR ENDED DECEMBER 31, 1997

     REVENUES.  Pro forma revenues for 1997 were $150.0 million. The Industrial
Wastewater Division generated $123.0 million, or 82.0%, of such pro forma
revenues. Tipping and collection fees contributed $81.3 million, or 66.1%, of
the Industrial Wastewater Division's 1997 pro forma revenues and by-product
sales contributed the remaining $41.7 million, or 33.9%, of the Industrial
Wastewater Division's 1997 pro forma revenues. Brokered sales of ethanol
constituted $18.5 million of the by-product sales of the Industrial Wastewater
Division. The Oilfield Waste Division generated $27.0 million, or 18.0%, of 1997
pro forma revenues.

     OPERATING EXPENSES.  Pro forma operating expenses for 1997 were $101.9
million or 67.9% of pro forma revenues.

                                       20
<PAGE>
     DEPRECIATION AND AMORTIZATION.  Pro forma depreciation and amortization
expenses for 1997 were $9.0 million, which represented 6.0% of pro forma
revenues.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Pro forma selling, general
and administrative expenses for 1997 were $18.2 million. As a percentage of pro
forma revenues, pro forma selling, general and administrative expenses were
12.1%. Included in the $18.2 million were $462,000 of pooling expenses.
Excluding this one-time charge, pro forma selling, general and administrative
expenses as a percentage of pro forma revenues would have been 11.8%.

     INTEREST AND OTHER EXPENSES.  Pro forma net interest and other expenses for
1997 were $1.7 million.

     INCOME TAXES.  The pro forma provision for income taxes for 1997 was $7.9
million. The assumed effective tax rate for the period was 41.0%.

HISTORICAL RESULTS FOR THE QUARTERS ENDED MARCH 31, 1998 AND 1997

     REVENUES.  Revenues for the quarter ended March 31, 1998 increased $4.5
million, or 57.0%, from $7.9 million for the quarter ended March 31, 1997 to
$12.3 million for the quarter ended March 31, 1998. The Industrial Wastewater
Division contributed $3.6 million, or 45.6%, of first quarter 1997 historical
revenues and $7.3 million, or 59.3%, of first quarter 1998 historical revenues.
Tipping and collection fees generated $824,000, or 22.2%, and $4.3 million, or
58.9%, of the Industrial Wastewater Division's historical revenues for the first
quarters of 1997 and 1998, respectively. By-product sales generated the
remaining $2.8 million, or 77.8%, and $3.0 million, or 41.1%, of the Industrial
Wastewater Division's historical revenues for the first quarters of 1997 and
1998, respectively. The Oilfield Waste Division contributed $4.3 million, or
54.4%, of first quarter 1997 historical revenues and $5.0 million, or 40.7%, of
first quarter 1998 historical revenues. Businesses acquired since the Company's
IPO in August 1997 accounted for $2.9 million, or 23.6%, of historical revenues
for the first quarter of 1998.

     The revenues of the Industrial Wastewater Division increased $3.7 million,
or 102.8%, from $3.6 million for the quarter ended March 31, 1997 to $7.3
million for the quarter ended March 31, 1998 due to acquisitions completed
during the fourth quarter of 1997 and the first quarter of 1998 which were
accounted for using the purchase method of accounting and an increase in the
volume of waste processed resulting primarily from the enactment of state-wide
"full-pump" regulations in Texas. The Oilfield Waste Division's revenues
increased $759,000, or 17.7%, from $4.3 million for the quarter ended March 31,
1997 to $5.0 million for the quarter ended March 31, 1998 due to an increase in
the volume of waste processed resulting from increased drilling activity in the
Gulf Coast region and an increase in tipping fees which became effective in the
third quarter of 1997.

     OPERATING EXPENSES.  Operating expenses increased $2.3 million, or 50.0%,
from $4.7 million for the quarter ended March 31, 1997 to $7.0 million for the
quarter ended March 31, 1998. As a percentage of revenues, operating expenses
decreased from 59.5% in the first quarter of 1997 to 56.8% in the first quarter
of 1998. This improvement was due primarily to an increase in tipping and
collection revenues, which have higher margins than by-product sales, in the
1998 period, as well as increased efficiencies resulting from higher volumes and
operational enhancements.

     DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expenses
increased $354,000, or 55.9%, from $633,000 for the quarter ended March 31, 1997
to $987,000 for the quarter ended March 31, 1998. As a percentage of revenues,
depreciation and amortization expenses remained relatively constant at a rate of
8.1% for the first quarter of 1997 and 8.0% for the first quarter of 1998.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased $777,000, or 112.6%, from $690,000 for the
quarter ended March 31, 1997 to $1.5 million for the quarter ended March 31,
1998. As a percentage of revenues, selling, general and administrative expenses
increased from 8.8% for the first quarter of 1997 to 11.9% for the first quarter
of 1998. This increase was primarily due to higher personnel costs and
professional fees associated with being a public company and the establishment
of the Company's corporate offices in Houston in May of 1997.

                                       21
<PAGE>
     INTEREST AND OTHER EXPENSES.  Net interest and other expenses decreased
$140,000, or 29.1%, from $481,000 for the quarter ended March 31, 1997 to
$341,000 for the quarter ended March 31, 1998. This decrease resulted primarily
from the use of a portion of the proceeds from the Company's IPO in August 1997
to reduce debt.

     INCOME TAXES.  The provision for income taxes increased $498,000, or 98.8%,
from $504,000 for the quarter ended March 31, 1997 to $1.0 million for the
quarter ended March 31, 1998 as a result of increased taxable income. The
effective tax rate for the period ended March 31, 1997 was 36.4% compared to a
39.5% rate for the period ended March 31, 1998.

HISTORICAL RESULTS FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996

     REVENUES.  Revenues increased $23.9 million, or 167.1%, from $14.3 million
in 1996 to $38.2 million in 1997. The Industrial Wastewater Division contributed
$13.5 million, or 94.4%, of 1996 revenues and $18.2 million, or 47.6%, of 1997
revenues. By-product sales generated $11.4 million, or 84.4%, of the Industrial
Wastewater Division's revenues in 1996 and $12.5 million, or 68.7%, in 1997.
Tipping and collection fees generated $2.1 million, or 15.6%, of the Industrial
Wastewater Division's revenues in 1996 and $5.7 million, or 31.3%, in 1997. The
Oilfield Waste Division contributed $826,000, or 5.6%, of revenues in 1996 and
$20.0 million, or 52.4%, of revenues in 1997. The Company purchased the Oilfield
Waste Division under the purchase method of accounting in December 1996.

     Revenues of the Industrial Wastewater Division increased $4.7 million, or
34.8%, from $13.5 million in 1996 to $18.2 million in 1997. This increase was
attributable to an 180.1% increase in volume of waste processed and an 8.8%
increase in by-product sales. The Oilfield Waste Division's revenues increased
$19.2 million from $826,000 in 1996 to $20.0 million in 1997 as a result of the
inclusion of the Oilfield Waste Division for all of 1997 as compared to less
than one month in 1996.

     OPERATING EXPENSES.  Operating expenses increased $10.0 million, or 87.8%,
from $11.4 million in 1996 to $21.4 million in 1997, primarily due to the
inclusion of the Oilfield Waste Division for all of 1997 as compared to less
than one month in 1996. As a percentage of revenues, operating expenses
decreased from 79.6% for 1996 to 56.0% for 1997. This improvement reflects
higher operating margins derived by the Oilfield Waste Division as opposed to
the Industrial Wastewater Division.

     DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expenses
increased $2.6 million, or 605.2%, from $424,000 in 1996 to $3.0 million in
1997. As a percentage of revenues, depreciation and amortization expenses
increased from 3.0% in 1996 to 7.8% in 1997. The increase in depreciation and
amortization expenses resulted primarily from the acquisition of the Oilfield
Waste Division.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased $4.4 million, or 300.1%, from $1.4 million in
1996 to $5.8 million in 1997. The majority of this increase related to the
inclusion of the Oilfield Waste Division for all of 1997 as compared to less
than one month in 1996. Selling, general and administrative expenses increased
from 10.1% of 1996 revenues to 15.1% of 1997 revenues, primarily due to higher
personnel costs and professional fees associated with being a public company and
establishing the Company's corporate offices in Houston in May 1997.

     INTEREST AND OTHER EXPENSES.  Net interest and other expenses increased
$1.5 million, or 474.4%, from $309,000 in 1996 to $1.8 million in 1997. Net
interest and other expenses increased primarily as a result of interest expense
related to debt incurred in acquiring the Oilfield Waste Division in 1996 and
other businesses in 1997.

     INCOME TAXES.  The provision for income taxes increased $2.2 million, or
847.5%, from $255,000 in 1996 to $2.4 million in 1997. This increase resulted
primarily from additional taxable income. The effective tax rate for 1996 was
34.2% of income and the effective tax rate for 1997 was 38.4% of income.

HISTORICAL RESULTS FOR THE YEARS ENDED DECEMBER 31, 1996 AND 1995

     REVENUES.  All revenues in 1995 and 94.4% of revenues in 1996 were
generated by the Industrial Wastewater Division. Revenues increased $3.2
million, or 28.4%, from $11.1 million in 1995 to $14.3 million in 1996.
By-product sales contributed $9.8 million, or 88.3%, of the Company's revenues
in 1995

                                       22
<PAGE>
and $11.4 million, or 79.7%, of the Company's revenues in 1996. Tipping and
collection fees received by the Industrial Wastewater Division contributed $1.3
million, or 11.7%, of the Company's revenues in 1995 and $2.1 million, or 14.7%,
of the Company's revenues in 1996. The Oilfield Waste Division contributed
$826,000, or 5.6%, of revenues in 1996.

     By-product sales increased by $1.6 million, or 16.3%, from $9.8 million in
1995 to $11.4 million in 1996. Tipping and collection fees increased by
$750,000, or 56.3%, from $1.3 million in 1995 to $2.1 million in 1996. The
increase in revenues from the sale of by-products was due to an increase in
volumes and an increase in the average price per pound. The increase in the
volume of tipping and collection fees resulted primarily from growth of the
Houston market. The increase in the average price per pound was primarily
attributable to revenues obtained in the Company's acquisition of a collection
business in March 1996.

     OPERATING EXPENSES.  Operating expenses increased $1.6 million, or 16.3%,
from $9.8 million in 1995 to $11.4 million in 1996. As a percentage of revenues,
operating expenses decreased from 87.9% in 1995 to 79.6% in 1996. This
improvement was attributable to increased sales of by-products, lower per unit
processing costs, lower per unit costs of raw materials and increased revenues
from processing operations, offset in part by increased personnel expenses.

     DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expenses
increased $265,000, or 166.7%, from $159,000 in 1995 to $424,000 in 1996. As a
percentage of revenues, depreciation and amortization expenses increased from
1.4% in 1995 to 3.0% in 1996. This increase was attributable to acquisitions of
additional depreciable assets during 1996.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased $574,000, or 66.5%, from $863,000 in 1995 to
$1.4 million in 1996. As a percentage of revenues, selling, general and
administrative expenses increased from 7.8% in 1995 to 10.1% in 1996. The
majority of the increase relates to the addition of the Oilfield Waste Division
at the end of 1996.

     INTEREST AND OTHER EXPENSES.  Net interest and other expenses increased
$132,000, or 74.6%, from $177,000 in 1995 to $309,000 in 1996. Net interest and
other expenses increased primarily as a result of interest expense related to
the acquisition of the Oilfield Waste Division.

     INCOME TAXES.  The provision for income taxes increased by $206,000, or
420.4%, from $49,000 in 1995 to $255,000 in 1996. The effective tax rate for
1995 was 32.2% and the effective tax rate for 1996 was 34.2%.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's net working capital increased from $2.1 million at December
31, 1997 to $5.5 million at March 31, 1998. Improvement in the working capital
position was attributable primarily to an increase in current assets resulting
from borrowings at the end of the first quarter under the Company's Credit
Facility to fund acquisitions completed in the second quarter of 1998.

     The Company's capital requirements for its continuing operations consist of
its general working capital needs, scheduled principal payments on its debt
obligations and capital leases, and planned capital expenditures. At March 31,
1998, approximately $1.3 million of principal payments on debt obligations were
payable during the next twelve months. Capital expenditures for the last three
quarters of 1998 are budgeted at approximately $11.0 million. Of this amount,
approximately $1.8 million is budgeted to be invested in the Oilfield Waste
Division on equipment replacements and landfarm expansions. The remaining amount
is budgeted to be invested in the Industrial Wastewater Division for plant
expansions, equipment and vehicle upgrades.

     At March 31, 1998, the Company had established a $3.2 million reserve to
provide for the cost of future closures of landfarms. The amount of this
unfunded reserve is based on the estimated total cost to the Company of closing
the facilities as calculated in accordance with the applicable regulations.
Applicable regulatory agencies require the Company to post financial assurance
with the agencies to assure that all

                                       23
<PAGE>
waste will be treated and the facilities closed appropriately. The Company has
in place a total of $4.0 million of financial assurance in the form of letters
of credit and bonds.

     The Company has a $100.0 million Credit Facility with a group of banks
under which the Company may borrow to fund working capital requirements and
acquisitions. Amounts outstanding under the Credit Facility are secured by,
among other things, a lien on all or substantially all of the Company's assets.
The Credit Facility prohibits the payment of dividends and requires the Company
to comply with certain financial covenants. The Credit Facility also requires
the banks' consent for any acquisition by the Company of all or substantially
all of the assets or stock of any business. Upon completion of this offering,
the banks' consent will be required for acquisitions in which either (i) the
aggregate consideration to be paid by the Company (including any debt assumed or
issued) exceeds $15 million, or (ii) the aggregate consideration to be paid in
cash by the Company exceeds $10 million. The Company does not believe that these
restrictions will have a material adverse effect on the Company's ability to
fulfill its current acquisition program. The debt outstanding under the Credit
Facility may be accelerated at the option of the lenders in the event that,
among other things, a change in control of the Company occurs or Michael P.
Lawlor, W. Gregory Orr or Earl J. Blackwell ceases to serve as an executive
officer of the Company and is not replaced within sixty days by an individual
reasonably satisfactory to the lenders. After the consummation of this offering
and the application of the net proceeds therefrom, the Company anticipates that
it will have no borrowings outstanding under the Credit Facility. Amounts
currently outstanding under the Credit Facility bear interest at approximately
7.9%, which rate is anticipated to decrease pursuant to the terms of the Credit
Facility to approximately 6.9% after the consummation of this offering. See
"Use of Proceeds."

     The Company's capital resources consist of cash reserves, cash generated
from operations and funds available under the Credit Facility. The Company
expects that these resources will be sufficient to fund continuing operations
for at least the next twelve months. In addition to capital required for its
ongoing operations, the Company will require additional capital to pursue its
acquisition program. The Company anticipates that future acquisitions will be
made using a combination of Common Stock and cash, much of which is expected to
be derived from borrowings under the Credit Facility. In addition, the Company
may seek to raise additional equity capital for all or a substantial part of the
consideration to be paid for future acquisitions or to reduce its debt. In the
event that the Common Stock does not maintain a sufficient market value or
potential acquisition candidates are unwilling to accept Common Stock as part of
the consideration for the sale of their businesses, the Company would be
required to utilize more of its cash resources in order to continue its
acquisition program. At the same time, the Company may be unable to raise
additional capital due to market conditions. As a result, the timing of
acquisitions over the longer term can be expected to be affected by prevailing
market conditions. In addition, if the Company were unable to secure the capital
necessary to carry out its acquisition program, the implementation of the
Company's growth strategy would be adversely affected.

SEASONALITY

     It is expected that the operations of the Oilfield Waste Division will
experience certain seasonal patterns consistent with the oil and gas exploration
and production activity in the Gulf Coast. Generally, the volume of oilfield
waste delivered to the Oilfield Waste Division has been lowest in the first
quarter of each calendar year. Prices for oil and natural gas are expected to
continue to be volatile and affect demand for the Company's oilfield waste
services. Certain of the Industrial Wastewater Division's processing facilities
in the Northeast and Midwest may be affected by adverse weather conditions.

YEAR 2000 COMPLIANCE

     Many existing computer programs use only two digits to identify a year in
the date field. These programs were designed and developed without considering
the impact of the upcoming change in the century. If not corrected, such
computer applications could fail or create erroneous results by or at the Year
2000. The Company has determined that its computer programs are Year 2000
compliant. When the Company completes an acquisition, it replaces the acquired
company's systems with its own management reporting and control systems.
Accordingly, the Company does not believe that its acquisition program will be
adversely affected by Year 2000 compliance issues.

                                    BUSINESS

GENERAL

     The Company is a rapidly growing provider of integrated liquid waste
management services, including collection, processing, recovery and disposal
services. The Company's primary focus of operations is industrial and commercial
wastewater treatment, although the Company also collects, processes and disposes
of oilfield waste. The Company operates 34 processing facilities located in
eight states and serves over 20,000 customers. The services provided by the
Company to any particular customer vary depending on the type of liquid waste
generated, local regulations and the treatment capabilities of local POTWs.

     The Company has adopted an acquisition-based growth strategy and intends to
continue its expansion, generally through (i) acquiring liquid waste processing
facilities; (ii) securing captive waste streams for its facilities by acquiring
collection companies and by entering into long-term contracts directly with
customers or collection companies; and (iii) integrating acquired companies into
the Company's operations to achieve operating efficiencies and economies of
scale. The Company believes that the liquid waste industry is highly fragmented
and that substantial acquisition opportunities exist throughout North America.
Since the Company's IPO in August 1997, the Company has acquired 20 businesses,
which collectively had 1997 pro forma revenues of approximately $111.8 million.

     The Company provides liquid waste management services through a number of
subsidiaries which are organized into two divisions. The Industrial Wastewater
Division collects, processes and disposes of liquid waste (such as industrial
wastewater, grease and grit trap waste, bulk liquids and unsaleable beverages,
and certain hazardous wastes) and recovers saleable by-products (such as fats,
oils, feed proteins, ethanol and solvents) from certain of the waste streams.
Typically, the Company uses a variety of physical, chemical, thermal and
biological techniques to break down the liquid waste into constituent
components. Water extracted from the liquid waste is pretreated and then
discharged into a POTW and solid materials are dried and disposed of in a solid
waste landfill. The Oilfield Waste Division collects, processes and disposes of
waste generated in oil and gas exploration and production. The Company's
Industrial Wastewater Division generated 82.0% of the Company's 1997 pro forma
revenues of $150.0 million and the Oilfield Waste Division generated the
remaining 18.0% of such pro forma revenues.

     The Company's executive offices are located at 411 N. Sam Houston Parkway
East, Suite 400, Houston, Texas 77060-3545, and its telephone number is (281)
272-4500.

INDUSTRY BACKGROUND

     The wastewater treatment market is generally divided into two segments:
industrial and commercial wastewater treatment, and municipal wastewater
treatment. Industrial and commercial companies produce various types of
wastewater (including hydrocarbon contaminated water, landfill leachate,
unsaleable beverages and grease and grit trap waste) that must be treated prior
to disposal in POTWs or for which municipalities charge higher rates to treat.
Similarly, oil and gas exploration and production companies produce liquid waste
that must be disposed of in accordance with federal and state regulations.
Municipalities utilize or contract with third parties for the utilization of
water treatment technology to treat municipal wastewater.

     According to The McIlvaine Company, the global water and wastewater
treatment market was approximately $335 billion in 1995 and is expected to
increase to over $500 billion in 2000, reflecting a projected compound annual
growth rate of approximately 8.7%. The McIlvaine Company further estimated that,
in 1995, the worldwide costs of treating municipal wastewater were $90 billion
and the worldwide costs of treating industrial wastewater were $25 billion. The
Company believes that the liquid waste industry is comprised of thousands of
relatively small owner-operated businesses, presenting significant opportunities
for consolidation.

     In the United States, the growth in demand for wastewater treatment
services has been driven by many factors, including (i) municipalities refusing
to accept certain industrial wastewaters due to limited treatment capabilities
and a lack of the resources needed to expand or modernize their POTWs,

                                       25
<PAGE>
(ii) industrial and commercial businesses avoiding POTW surcharges by using
third parties to process and dispose of their wastewater, (iii) industrial and
commercial businesses outsourcing their wastewater treatment needs, (iv)
continued industrial and commercial expansion, and (v) increasingly strict
regulations governing the disposal of wastewater, as well as more stringent
enforcement of such regulations.

     REJECTION OF CERTAIN WASTEWATERS BY POTW.  In North America, governmental
regulation and enforcement have established strict standards for potable water
and the discharge of pollutants in wastewater. Municipalities have spent
billions of dollars building water purification and wastewater treatment
facilities. Historically, the municipalities have also managed these facilities.
However, many of these municipalities are facing increasing budgetary
constraints and damage to their wastewater treatment facilities caused by grease
and other liquid wastes and, thus, are seeking alternatives to maintaining and
upgrading their aging facilities. In addition to outsourcing the operation, or
transferring ownership, of their facilities, many municipalities have begun
refusing to accept certain liquid waste streams, thereby increasing the demand
for wastewater treatment services provided by the private sector. For example,
the Dallas, Houston and San Antonio POTWs do not accept grease or grit trap
waste. In addition, in late 1997, the Houston POTWs ceased accepting septage
generated outside the Houston city limits.

     ECONOMIC BENEFIT OF PRETREATING CERTAIN WASTEWATERS.  For years, generators
of industrial wastewater and other liquid waste have discharged the waste
directly into POTWs. However, the difficulties encountered by POTWs in
collecting and treating certain wastewaters have caused many municipalities to
increase the rates charged for accepting these wastewaters. With respect to
certain wastewaters, it is more economical for the generator to deliver the
waste to liquid waste service providers such as the Company than to discharge
the waste directly into the POTW. For example, it is currently more economical
for many soft drink manufacturers to deliver their unsaleable beverages to the
Company for processing and disposal than to discharge the beverages directly
into the POTW.

     OUTSOURCING BY INDUSTRIAL AND COMMERCIAL BUSINESSES.  Industrial and
commercial businesses have continued to focus on their primary business
activities and to downsize and outsource secondary business activities in which
they may not have much expertise. By outsourcing their wastewater treatment
needs, industrial and commercial businesses can free-up capital for investment
in their primary products and business activities, eliminate a significant
portion of their overhead and transfer risk to experts in the field.

     ECONOMIC EXPANSION.  Many industrial companies have significantly expanded
their manufacturing and processing facilities. This industrial expansion has
increased the amount of wastewater generated. In addition, continued commercial
expansion throughout North America has generated additional grease and grit trap
waste and other liquid waste that must be processed by the generators thereof,
POTWs or liquid waste service providers such as the Company.

     INCREASINGLY STRICT REGULATIONS.  Heightened public concern about water
quality has caused federal, state and local governments to adopt increasingly
strict regulations governing the processing and disposal of industrial
wastewater and other liquid wastes. For example, effective as of October 1993,
Subtitle D of RCRA banned the disposal of untreated bulk liquid waste in
landfills. In addition, effective in March 1997, the Texas Natural Resource
Conservation Commission (the "TNRCC") implemented state-wide "full pump"
regulations requiring 100% evacuation of all grease and grit traps and proper
disposal of the full volume of each trap. Louisiana, Michigan, Texas and certain
other oil and gas producing states have enacted comprehensive laws and
regulations governing the proper management of oilfield waste. Under Louisiana,
Michigan and Texas regulations, if oilfield waste cannot be processed for
discharge or disposed of at the well where it is generated, it must be
transported to a licensed oilfield waste processing or disposal facility. In
addition, federal regulations also restrict, and in some cases prohibit
entirely, the discharge of oilfield waste into U.S. waters.

STRATEGY

     The Company's objective is to continue to grow throughout North America by
expanding its services in markets where it can be one of the largest and most
profitable integrated liquid waste management service companies. The Company
believes that as it expands it is likely to gain numerous competitive

                                       26
<PAGE>
advantages relative to smaller operators, including servicing multiple customer
locations, treating a wide variety of liquid waste streams, achieving operating
efficiencies (including collection route densification and consolidation, and
increased equipment and facility utilization) and increased economies of scale
(including access to lower-cost capital, lower insurance rates, decreased
proportional selling, general and administrative costs and increased purchasing
power), and adapting to changing regulations. The Company's strategy for
achieving its objective is to (i) expand through acquisitions; (ii) generate
internal growth; (iii) enhance existing and acquired operations; and (iv)
operate its businesses on a decentralized basis. The Company intends to
implement this strategy as follows:

     EXPAND THROUGH ACQUISITIONS.  The Company intends to continue to expand by
acquiring liquid waste management businesses in new markets, while increasing
its facility and equipment utilization and expanding its market penetration and
range of services offered in its existing markets through "tuck-in"
acquisitions. In considering new markets, the Company will generally seek to
acquire a liquid waste processing facility that has the customer base, technical
skills and infrastructure necessary to be a core business into which other
liquid waste operations can be consolidated. After the Company has acquired a
processing facility, it will typically seek to increase the utilization of the
facility by securing captive waste streams, which includes acquiring collection
companies and entering into contracts to collect or accept all of the various
types of liquid waste generated by customers. The Company will also seek to
acquire other liquid waste businesses that can be integrated into its existing
operations or utilized to provide additional liquid waste services to the same
customer base.

     INTERNAL GROWTH.  In order to generate continued internal growth, the
Company has focused on increasing sales penetration in its current and adjacent
markets, soliciting new commercial and industrial customers, expanding its
collection infrastructure, marketing upgraded services to existing customers
and, where appropriate, raising prices. The Company believes that there are a
number of liquid waste generators that would prefer to have a single source
provider for the collection, processing and disposal of all of their liquid
waste streams, but are unable to do so because the liquid waste industry is
highly fragmented. The Company intends to expand its customer base by
positioning itself as a multi-city, single source provider for national and
regional generators of liquid waste. In addition, the Company intends to expand
the capacity and processing capabilities of its existing liquid waste
facilities, and is seeking to amend its permit for certain facilities in order
to receive additional liquid waste streams.

     OPERATIONAL ENHANCEMENTS.  The Company will seek to enhance the operations
of its existing facilities and acquired businesses through collection route
densification and consolidation and increased facility and equipment
utilization. The Company also expects to realize cost savings by consolidating
certain administrative functions at its corporate offices, such as cash
management, human resources, finance and insurance.

     OPERATE ON DECENTRALIZED BASIS.  The Company intends to continue to manage
its various businesses on a decentralized basis, with local management
maintaining responsibility for the day-to-day operations, profitability and
growth of the business, while the executive officers of the Company exercise
strong strategic and financial oversight. The Company believes that such a
decentralized operating structure will retain the entrepreneurial spirit present
in each of the acquired businesses and allow the Company to capitalize on the
considerable local and regional market knowledge and customer relationships
possessed by each acquired business.

ACQUISITION PROGRAM

     Since its IPO in August 1997, the Company has pursued an aggressive
acquisition program, acquiring 20 liquid waste management businesses. The
Company believes that numerous acquisition candidates meeting the Company's
acquisition criteria, including "tuck-in" opportunities, exist within its
existing markets and in new geographic areas.

     The Company has assembled an experienced acquisition team comprised of
operations, environmental, engineering, legal, financial and accounting
personnel to identify and evaluate acquisition opportunities. The Company has
established pre-acquisition review procedures for acquisition candidates,
including legal,

                                       27
<PAGE>
financial, engineering, operational and environmental reviews. The environmental
reviews include, where appropriate, investigation of geologic, hydrogeologic and
other site conditions, past and current operations (including types of waste
processed and disposed of), design and construction records, permits, regulatory
compliance history, regulatory agency records and available soil sampling,
groundwater and air monitoring results. Senior management of the Company is
actively involved in identifying and evaluating acquisition candidates.

     In considering whether to proceed with an acquisition, the Company
evaluates a number of factors, including (i) the acquisition candidate's
historical and projected financial results; (ii) any expected synergies with one
or more of the Company's existing operations; (iii) the proposed purchase price
and the expected impact on results of operations and on the Company's earnings
per share; (iv) whether the candidate will enhance the Company's ability to
effect other acquisitions in the vicinity; (v) the capabilities and experience
of senior management of the candidate; (vi) the candidate's customer service
reputation and relationships with the local communities; (vii) the composition
and size of the candidate's customer base; (viii) the types of services provided
by the candidate; and (ix) whether the candidate has definable and controllable
liabilities, including potential environmental liabilities.

     The Company has also established a detailed process for integrating newly
acquired businesses. This process is designed to achieve operating compatibility
with maximum speed and efficiency, and with minimum disruption of ongoing
business. Once a liquid waste business is acquired, the Company implements
programs and policies for the business designed to reduce costs and improve
operating efficiencies and overall profitability. For example, the Company
replaces the acquired business' computer systems with its own management
reporting and control system. The Company typically seeks to retain the acquired
business' qualified managers and key employees, while consolidating certain
overhead functions such as cash management, human resources, finance and
insurance through the Company's corporate offices.

     The Company believes it will be regarded by certain acquisition candidates
as an attractive acquiror because of: (i) the Company's strategy for creating an
integrated and professionally managed national liquid waste company; (ii) the
Company's visibility and access to financial resources as a public company;
(iii) the potential for owners of the businesses being acquired to participate
in the Company's planned internal growth and growth through acquisitions, while
realizing liquidity; (iv) the Company's management team, which includes
individuals with significant experience operating businesses in the waste
management industry and executing consolidation strategies; and (v) the
Company's general philosophy of maintaining an acquired business' culture and
retaining its management through appropriate incentives.

     As consideration for future acquisitions, the Company intends to continue
to use various combinations of its Common Stock and cash. The consideration for
each future acquisition will vary on a case-by-case basis depending on the
financial interests of the Company and the owners of the business to be
acquired, and the historic operating results and future prospects of the
business. The Company intends to finance future acquisitions from cash generated
by operations, borrowings under the Credit Facility, and from the 1,682,901
shares of Common Stock remaining available for use under the Company's
acquisition shelf registration statement.

ACQUISITIONS

     The Company has acquired 23 businesses since its formation in November
1996. The consideration for these acquisitions consisted of cash, notes and
shares of Common Stock. In addition, in some transactions, the Company has
agreed to issue additional shares of Common Stock if the future pre-tax earnings
of the acquired business exceed certain negotiated levels or other specified
events occur.

OPERATIONS AND SERVICES PROVIDED

     Industrial and commercial businesses produce various types of wastewater
(including hydrocarbon contaminated water, landfill leachate, unsaleable
beverages, and grease and grit trap wastes) that must be disposed of in
accordance with federal, state and local regulations. Similarly, oil and gas
exploration and production companies produce liquid waste that must be disposed
of in accordance with federal and state regulations. As demonstrated in the
diagram on the inside front cover page, the Company accepts liquid waste from
the generator thereof or an independent collection company, processes the liquid
waste to remove contaminants and then disposes of the liquid waste in accordance
with applicable regulations. In

                                       29
<PAGE>
addition, in certain instances, the Company's processing operations generate
saleable by-products. The Company's services permit generators of liquid waste
to focus on their primary business activities and transfer the risks associated
with the processing and disposal of the waste to experts in the field.

     The Company collects, processes, recovers and disposes of liquid waste
through a number of subsidiaries that are organized into two divisions -- the
Industrial Wastewater Division and the Oilfield Waste Division. The operations
of these two divisions are summarized below.

INDUSTRIAL WASTEWATER DIVISION

     Through its Industrial Wastewater Division, which contributed approximately
82% of the Company's 1997 pro forma revenues, the Company receives fees to
collect, process and dispose of liquid waste such as industrial wastewater,
grease trap and grit trap waste, bulk liquids and unsaleable beverages,
biosolids and oil-contaminated water. In addition, the Industrial Wastewater
Division generates revenues from the sale of by-products, including fats, oils,
feed proteins, industrial and fuel grade ethanol, solvents, aluminum, glass,
plastic and cardboard, recovered from waste streams. Some of the Company's
by-product sales involve brokering of industrial and fuel grade ethanol produced
by third parties in order to meet its customers' volume and quality
requirements. The Industrial Wastewater Division operates a fleet of
approximately 335 vehicles to collect waste directly from over 20,000 customers,
receives waste from independent transporters servicing thousands of additional
generators and also receives waste shipped directly by the generators thereof
via rail and truck. Brief descriptions of the types of liquid waste most
commonly managed by the Industrial Wastewater Division are set forth below:

     INDUSTRIAL WASTEWATERS.  Industrial wastewaters such as hydrocarbon
contaminated water, landfill leachate and printing solvents are transported to
the Company's facilities in vacuum trucks, trailers and other transportable
containers. Using a variety of physical, chemical, thermal and biological
techniques, the liquid waste is broken down into constituent components. Water
extracted from the liquid waste is pretreated and then discharged into the POTW
and solid materials are dried and disposed of in a solid waste landfill. In some
instances, such as printing solvents, the contaminated materials are processed
and returned to the generator for reuse.

     GREASE AND GRIT TRAP WASTE.  Grease trap waste from restaurants and other
food manufacturing and preparation facilities and grit trap waste from car
washes is collected by Company vehicles or independent third parties and
transported to the Company's facilities. Grease and grit trap waste is processed
using a variety of physical, chemical, thermal and biological techniques. Water
extracted from the liquid waste is pretreated and then discharged into the POTW
and solid materials are dried and disposed of in a solid waste landfill.
By-products recovered from grease trap waste are processed with used cooking oil
and other food processing residuals purchased by the Company to produce fats,
oils and feed proteins of various grades which are sold to producers of
livestock feed and chemicals.

     BULK LIQUIDS AND UNSALEABLE BEVERAGES.  The Company accepts both liquid
residuals and unsaleable packaged beverages from breweries, soft drink
manufacturers and food processors. Water extracted from the liquid waste is
pretreated and then discharged into the POTW. The remaining liquid waste is
fermented and distilled into both industrial and fuel grade ethanol, which is
sold primarily to major oil and chemical companies. Packaging of the unsaleable
beverages, whether aluminum, glass, plastic or cardboard, is removed, separated
and sold to recycling firms.

     BIOSOLIDS.  The Company accepts liquid and dry cake biosolids, or sludge,
from municipal wastewater treatment facilities and private businesses and
processes these biosolids into a product that is sold for use as a fertilizer
and landfill cover.

     SEPTAGE.  Septage is pumped from septic tanks by Company vehicles or
independent third parties and transported to the Company's facilities. The
septage is then processed using a variety of physical, chemical, thermal and
biological techniques. Water extracted from the liquid waste is pretreated and
then discharged into the POTW and solid materials are dried and disposed of in a
solid waste landfill.

                                       30
<PAGE>
     HAZARDOUS WASTES.  Hazardous wastes such as household hazardous wastes,
plating solutions, acids, caustic, oxidizers, and flammable and reactive wastes
are transported to certain of the Company's facilities in tankers, trucks and
other transportable containers and by rail. Wastes suitable for treatment under
the Clean Water Act are directed into a suitable process such as neutralization,
chemical precipitation, filtration, biological degradation, carbon adsorption,
alcohol recovery and/or oil recycling. Sludge and solid hazardous wastes are
directed to the Company's chemical fixation facility to be pre-treated using
chemical oxidation or reduction followed by fixation using silicates such as
lime or cement kiln dust. Treated residues are tested in accordance with federal
and state requirements to meet the land disposal restrictions prior to disposal.
Solid and semi-solid residues are shipped to a Subtitle D landfill. Treated
listed waste residues are sent to an audited and approved Subtitle C landfill.

     PETROLEUM FUELS.  Contaminated and/or off-specification petroleum fuels and
used oil are transported to the Company's facilities in vacuum trucks, trailers
and other transportable oil containers. Using mechanical and gravity separation
techniques, these materials are processed to produce a fuel sold primarily to
operators of industrial furnaces. Resulting wastewater is transported to another
of the Company's facilities for processing and disposal. Solid materials and
sludges are sent to one of the Company's oilfield waste processing facilities.

     The Industrial Wastewater Division operates 21 liquid waste processing
facilities. The Company believes that the specialized equipment, licenses and
permits necessary to operate these liquid waste processing facilities create a
significant barrier to entry into this industry. The following table sets forth
certain information relating to each such facility, including the type of liquid
wastes most commonly managed:

  OILFIELD WASTE DIVISION

     The Oilfield Waste Division contributed approximately 18.0% of the
Company's 1997 pro forma revenues. At its six oilfield waste facilities located
in Louisiana, Michigan and Texas, the Oilfield Waste Division treats and
disposes of waste that is generated in the exploration for and production of oil
and natural gas. Oilfield waste consists primarily of oil-based and water-based
drilling fluids (which contain oil, grease, chlorides and heavy metals), as well
as cuttings, saltwater, workover and completion fluids, production pit sludges
and soil containing these materials.

     Landfarming, the treatment process utilized at four of the Company's
oilfield waste facilities, involves several distinct stages. Oilfield waste is
brought to the Company's facilities in trucks and on barges and the delivered
waste materials are then tested. Materials which do not qualify as permitted
oilfield waste in accordance with applicable state regulations are rejected.
Accepted waste is then loaded into treatment cells, which are flooded with fresh
water and mixed to dissolve salts and soluble materials. Saltwater is then
pumped out through a collection system and typically disposed of at a saltwater
injection well on-site. This flooding process is typically repeated several
times. The remaining waste is then processed to remove organic contamination
through biological degradation. Total treatment of a cell takes approximately
nine to twelve months. In the final stage, the remaining material is tested to
ensure compliance with regulatory requirements. Thereafter, the material is
transported to on-site stockpile areas.

     In connection with the Campbell Wells Acquisition, the Company acquired a
long-term Disposal Agreement with Newpark for the processing and disposal of
oilfield waste generated offshore in the Gulf Coast region. Under the terms of
the Disposal Agreement, until June 30, 2021, Newpark is obligated to deliver to
the Company the lesser of (i) one-third of the barrels of oilfield waste that
Newpark receives for processing and disposal in the Territory and (ii) 1,850,000
barrels of oilfield waste, in each case excluding saltwater. In return, until
August 2001, the Company is prohibited from accepting from any customer other
than Newpark oilfield waste generated in a marine environment or transported in
a marine vessel within the Territory. The price paid by Newpark under the
Disposal Agreement is currently $5.50 per barrel, adjusted semi-annually
beginning June 30, 1998, with a price floor of $5.50 per barrel. Although the
contract price is lower than the current market price for comparable waste,
Newpark's delivery obligations under the Disposal Agreement allow the Company to
eliminate virtually all marketing and transfer expenses on waste delivered under
the Disposal Agreement and, therefore, the Company believes that operating
margins on waste volume from Newpark and other customers are comparable. During
the twelve-month period ending December 31, 1997, Newpark delivered
approximately 1,430,000 barrels of oilfield waste, excluding saltwater, to the
Company's landfarms.

     Due to its arrangements with Newpark, the Company is focusing its marketing
efforts toward inland waste generators and, by so doing, the Company believes
that it will be able to increase the total amount of oilfield waste that is
delivered to the Oilfield Waste Division for processing and disposal.

     The Oilfield Waste Division operates six oilfield waste processing
facilities and seven commercial saltwater injection wells. The following table
sets forth certain information relating to each processing facility.

COMPETITION

     The liquid waste industry is highly fragmented and very competitive.
Competitors compete primarily on the basis of proximity to collection
operations, tipping fees charged and quality of service. With respect to certain
waste streams (such as oilfield waste, bulk liquids and unsaleable beverages)
the Company must compete with the generators of such waste streams, who
continually evaluate the decision whether to use internal disposal methods or
utilize a third party disposal company such as the Company. The Company must
also compete with area landfills for certain waste streams. The Company competes
with Newpark and a number of smaller companies for oilfield waste produced on
land in the Gulf Coast region. Pursuant to the Newpark Disposal Agreement, until
August 2001, the Company is contractually prohibited from (i) accepting from any
customer other than Newpark oilfield waste generated in a marine environment or
transported in a marine vessel within the Territory and (ii) engaging in the
site remediation and closure business in the Territory. Pursuant to the terms of
the Campbell Wells Acquisition, until December 2001, the Company is also
prohibited from engaging in the collection, treatment or disposal of municipal
solid wastes, construction debris or demolition debris.

     The Company believes that there are certain barriers to entry in the liquid
waste industry. These barriers include formalized procedures for customer
acceptance, licenses, permits, and the need for specially equipped facilities
and trained personnel.

REGULATORY BACKGROUND

     The Company's business operations are affected both directly and indirectly
by governmental regulations, including various federal, state and local
pollution control and health and safety programs that are administered and
enforced by regulatory agencies. These programs are applicable or potentially
applicable to one or more of the Company's existing operations. Although the
Company intends to make capital expenditures to expand its liquid waste
processing capabilities, the Company believes that it is not presently required
to make material capital expenditures to remain in compliance with federal,
state and local laws and regulations relating to the protection of the
environment. See "Risk Factors -- Dependence Upon Oilfield Waste Exemption
Under RCRA and Other Environmental Regulations" and "-- Failure To Comply with
Governmental Regulations."

  THE CLEAN WATER ACT

     The Company treats and discharges wastewaters at its liquid waste
facilities and at its oilfield waste landfarms. These activities are subject to
the requirements of the Clean Water Act and comparable state statutes and
federal and state enforcement of these regulations. The Clean Water Act
regulates the discharge of pollutants into waters of the United States. The
Clean Water Act establishes a system of standards, permits and enforcement
procedures for the discharge of pollutants from industrial and municipal
wastewater sources. The law sets treatment standards for industries and
wastewater treatment plants and provides federal grants to assist municipalities
in complying with the new standards. In addition to requiring permits for
industrial and municipal discharges directly into the waters of the United
States, the Clean Water Act also requires pretreatment of industrial wastewater
before discharge into municipal systems. The Clean Water Act gives the EPA the
authority to set pretreatment limits for direct and indirect industrial
discharges. In addition, the Clean Water Act prohibits certain discharges of oil
or hazardous substances and authorizes the federal government to remove or
arrange for removal of such oil or hazardous substances. The Clean Water Act
also requires the adoption of the National Contingency Plan to cover removal of
such materials. Under the Clean Water Act, the owner or operator of a vessel or
facility may be liable for penalties and costs incurred by the federal
government in responding to a discharge of oil or hazardous substances.

     The Clean Water Act also has a significant impact on the operations of the
Company's customers for oilfield waste services. EPA Region 6, which includes
the Company's current market, continues to issue new and amended National
Pollution Discharge Elimination System ("NPDES") general permits further
limiting or restricting substantially all discharges of produced water from the
Oil and Gas Extraction Point Source Category into waters of the United States.
These permits include:

      o   Onshore subcategory permits for Texas, Louisiana, Oklahoma and New
          Mexico (56 Fed. Reg. 7698). These permits completely prohibit the
          discharge of drilling fluids, drill cuttings,

                                       33
<PAGE>
          produced water or sand, and various other oilfield wastes generated by
          onshore operations into waters of the United States. These permits
          have the effect of requiring that most oilfield wastes follow
          established state disposal programs. These general permits expired on
          February 25, 1996, but pursuant to EPA policy, they are considered to
          remain in effect until reissued by the EPA or superceded by other EPA
          action.

      o   Permits for produced water and produced sand discharges into coastal
          waters of Louisiana and Texas issued on January 9, 1995 (60 Fed. Reg.
          2387). Coastal means "waters of the United States . . . located
          landward of the territorial seas." Under these regulations all such
          discharges were required to cease by January 1, 1997.

      o   The Outer Continental Shelf ("OCS") permit covering oil and gas
          operations in federal waters in the Gulf of Mexico (seaward of the
          Louisiana and Texas territorial seas) was reissued in November 1992
          and modified in December 1993. The existing permit was combined with a
          new source permit on August 9, 1996 (61 Fed. Reg. 41609). This permit
          prohibits certain discharges of drilling fluids and drill cuttings and
          includes stricter limits for oil and grease concentrations in produced
          waters to be discharged. These limits are based on the Best Available
          Treatment requirements contained in the Oil and Gas Offshore
          Subcategory national guidelines which were published March 3, 1993.
          Additional requirements include toxicity testing and bioaccumulation
          monitoring studies of proposed discharges. The combined permit expired
          on November 18, 1997; however, the expired permit will continue to be
          effective for permittees that applied for a new permit prior to the
          expiration date, until the EPA issues a new general permit for this
          area or requires permittees to seek individual permits.

      o   A permit for the territorial seas of Louisiana was issued on November
          4, 1997 (62 Fed. Reg. 59687). The permit became effective on December
          4, 1997, except for the water quality based limits and certain
          monitoring requirements that became effective May 4, 1998. The permit
          prohibits the discharge of drilling fluids, drill cuttings and
          produced sand. Produced water discharges are limited for oil and
          grease, toxic metals, organics, and chronic toxicity. The territorial
          seas part of the Offshore Subcategory begins at the line of ordinary
          low water along the part of the coast which is in direct contact with
          the open sea, and extends out three nautical miles. This permit covers
          both existing sources and new sources. All discharges in state waters
          must comply with any more stringent requirements contained in the
          Louisiana Water Quality Regulations, LAC 33.IX.7.708. A similar permit
          will be proposed for the Texas territorial seas in the future.

     The combined effect of all of these permits closely approaches a "zero
discharge" standard affecting all waters except those of the OCS. The Company
and many industry participants believe that these permits and the requirements
of the Clean Water Act may ultimately lead to a total prohibition of overboard
discharge in the Gulf of Mexico.

  RCRA

     RCRA is the principal federal statute governing hazardous and solid waste
generation, treatment, storage and disposal. RCRA and state hazardous waste
management programs govern the handling and disposal of "hazardous waste." The
EPA has issued regulations pursuant to RCRA, and states have promulgated
regulations under comparable state statutes, that govern hazardous waste
generators, transporters and owners and operators of hazardous waste treatment,
storage or disposal facilities. These regulations impose detailed operating,
inspection, training and emergency preparedness and response standards and
requirements for closure, financial responsibility, manifesting of wastes,
record-keeping and reporting, as well as treatment standards for any hazardous
wastes intended for land disposal. The Company does not accept hazardous waste
at any of its facilities other than the Detroit, Michigan, Tampa, Florida and
Shreveport, Louisiana facilities. Consequently, the vast majority of the
Company's activities are not subject to the requirements adopted under Subtitle
C of RCRA.

     The Company's Louisiana and Texas landfarms process and dispose of oilfield
waste, which is exempt from classification as a RCRA-regulated waste. At various
times in the past, proposals have been made to rescind the exemption that
excludes oilfield waste from regulation under RCRA. The repeal or modification
of this exemption by administrative, legislative or judicial process would
require the Company to change its

                                       34
<PAGE>
method of doing business and could have a material adverse effect on the
Company's business, financial condition and results of operations. There is no
assurance that the Company would have the capital resources available to do so,
or that it would be able to adapt its operations. See "Risk Factors -- Failure
to Comply with Governmental Regulations."

     RCRA also indirectly affects the Company's operations at its liquid waste
facilities by prohibiting, among other things, the disposal of certain liquid
wastes in landfills. This prohibition increases demand for the services provided
by the Company's Industrial Wastewater Division.

  CERCLA

     CERCLA provides for immediate response and removal actions coordinated by
the U.S. Environmental Protection Agency (the "EPA") for releases of hazardous
substances into the environment and authorizes the government, or private
parties, to respond to the release or threatened release of hazardous
substances. The government may also order persons responsible for the release to
perform any necessary cleanup. Liability extends to the present owners and
operators of waste disposal facilities from which a release occurs, persons who
owned or operated such facilities at the time the hazardous substances were
released, persons who arranged for disposal or treatment of hazardous substances
and waste transporters who selected such facilities for treatment or disposal of
hazardous substances. CERCLA has been interpreted to create strict, joint and
several liability for the cost of removal and remediation, other necessary
response costs and damages for injury to natural resources.

     Despite the current exemption of oilfield waste under RCRA, if the
Company's operations resulted in the release of or improper disposal of
hazardous substances, the Company could incur CERCLA liability. Although the
Company is not aware of any such event, the Company or a business acquired by
the Company may have disposed or arranged for disposal of hazardous substances
that could result in the imposition of CERCLA liability on the Company in the
future. In addition, the Company would incur CERCLA liability if any hazardous
substances at the Company's facilities leached down into groundwater.

     The Company is not aware of any claims against it or any of its
subsidiaries that are based on CERCLA. Nonetheless, the identification of one or
more sites at which cleanup action is required could subject the Company to
liabilities which could have a material adverse effect on the Company's
business, financial condition and results of operations.

  THE CLEAN AIR ACT

     The Clean Air Act provides for federal, state and local regulation of
emissions of air pollutants into the atmosphere. Any modification or
construction of a facility with regulated air emissions must be a permitted or
authorized activity. The Clean Air Act provides for administrative and judicial
enforcement against owners and operators of regulated facilities, including
substantial penalties. In 1990, the Clean Air Act was reauthorized and amended,
substantially increasing the scope and stringency of the Clean Air Act's
regulations. Compliance with the Clean Air Act is not expected to have a
material effect on the Company's business, results of operations or financial
condition.

  STATE AND LOCAL REGULATIONS

     Order 29-B of the Louisiana Department of Natural Resources contains
extensive rules regarding the generation, processing, storage, transportation
and disposal of oilfield waste. Under Order 29-B, on-site disposal of oilfield
waste is limited and subject to stringent guidelines. If these guidelines cannot
be met, oilfield waste must be transported and disposed of off-site in
accordance with the provisions of Order 29-B. Moreover, under Order 29-B, most,
if not all, active waste pits (a typical on-site disposal method used by inland
generators of oilfield waste) must be closed or modified to meet regulatory
standards; however, full enforcement of this portion of Order 29-B has been
deferred. The Texas Railroad Commission and the Michigan Department of
Environmental Quality have also promulgated detailed requirements for the
management and disposal of oilfield waste. Permits issued by state regulatory
agencies are required for each oilfield waste processing facility operating
within Louisiana, Michigan and Texas. The Company must perform tests before
acceptance of any oilfield waste, as well as during and after processing to
ensure compliance with all regulatory requirements. Short-term emergency rules
recently adopted by the Louisiana

                                       35
<PAGE>
Department of Natural Resources have increased the pre-treatment testing to be
conducted by the Company on oilfield waste delivered to the Company's Louisiana
landfarms.

     The closure of any of the Company's landfarms is also regulated by state
authorities. In general, closure of a landfarm involves a multi-phase process
whereby all injection wells at the landfarm are plugged and abandoned, all
surface equipment is removed from the site, the treatment cells and perimeter
containment levees are removed and the surface of the site is contoured and
vegetated. Additional regulatory requirements include monitoring the surface
runoff water, the soil pore water and the groundwater for a period of five
years. If, after five years, the water quality meets the requirements specified
in the state regulations, the site is certified as closed.

     The Company's liquid waste processing facilities are subject to direct
regulation by a variety of state and local authorities. Typically, the Company
is required to obtain processing, wastewater discharge and air quality permits
from state and local authorities to operate these facilities and to comply with
applicable regulations concerning, among other things, the generation and
discharge of odors and wastewater.

     States and localities into which the Company may expand, by acquisition or
otherwise, may now or in the future have regulations with positive or negative
effects on the Company. It is possible that state or local regulations could
adversely affect the Company's execution of its acquisition strategy. See "Risk
Factors -- Dependence Upon Oilfield Waste Exemption Under RCRA and Other
Environmental Regulations" and "Failure to Comply with Governmental
Regulations."

RISK MANAGEMENT

     The Company's business exposes it to substantial risks. For example, the
Company's services routinely involve the handling, storage and disposal of
nonhazardous regulated materials and wastes and, in some cases, the handling of
hazardous materials and wastes for its customers which are the generators of
such wastes. The Company could be held liable for improper cleanup and disposal,
which liability could be based upon statute, negligence, strict liability,
contract or otherwise. In addition, the Company often is required to indemnify
its customers or other third parties against certain risks related to the
services performed by the Company, including damages stemming from environmental
contamination.

     The Company has implemented various procedures designed to insure
compliance with applicable regulations and reduce the risk of damage or loss.
These include specified handling procedures and guidelines for regulated wastes,
ongoing training and monitoring of employees and maintenance of insurance
coverage. The Company carries a broad range of insurance coverages that
management considers adequate for the protection of its assets and operations.
This coverage includes general liability, comprehensive property damage,
workers' compensation and other coverage customary in its industries; however,
this insurance is subject to coverage limits and certain policies exclude
coverage from damages resulting from environmental contamination. A claim that
is not covered or only partially covered by insurance could have a material
adverse effect on the Company's business, results of operations and financial
condition. There is no assurance that insurance will continue to be available to
the Company, that the possible types of liabilities that may be incurred by the
Company will be covered by its insurance, that the Company's insurance carriers
will meet their obligations or that the dollar amount of such liabilities will
not exceed the Company's policy limits.

PROPERTIES

     The Company's corporate offices are located in Houston, Texas. The
corporate offices consist of approximately 6,800 square feet of office space
occupied under a lease which expires on June 1, 2002.

     In addition to the facilities described above in " -- Operations and
Services Provided," the Company also owns an administrative office in Fort
Worth consisting of approximately 2,000 square feet of office space and a
facility in Lacassine, Louisiana consisting of approximately 8,000 square feet
of office and equipment storage space and approximately 130 acres of undeveloped
land that was previously used for landfarming of oilfield waste and naturally
occurring radioactive material ("NORM"). In January 1997, the Company ceased
accepting NORM at the Lacassine facility and began taking the steps necessary to
close this facility in accordance with Louisiana law. The Company also owns a
facility in Kansas City, Missouri that was previously used for storage and
bulking of various hazardous wastes, a facility in Roseville,

                                       36
<PAGE>
Michigan that was previously used for fuel blending and solvent recycling and a
facility in Detroit, Michigan that was previously used in the solidification and
fixation of various types of waste. The Kansas City and Roseville facilities
have not been operational since 1992 and the Company has no plans to resume
operations at either of these facilities. The Detroit facility has ceased
accepting waste and will be closed in accordance with applicable law. The
Company also operates a transfer station in Portland, Oregon and two collection
and transportation facilities in Massachusetts.

     All of the Company's facilities satisfy its present needs; however, as part
of its internal growth strategy, the Company intends to expand the capacity and
processing capabilities of certain of its liquid waste processing facilities and
increase the number and types of permitted waste streams of such facilities. The
Company believes that the unutilized capacity of each of the leased landfarms is
sufficient for at least 25 years; which, in each case, exceeds the remaining
term (including options) of the lease agreement for such facility. The Company
also believes that the remaining capacity at each of the landfarms owned by the
Company is sufficient for at least 25 years.

LEGAL PROCEEDINGS

     Prior to the closing of the Campbell Wells Acquisition, four lawsuits were
brought against Campbell Wells based upon the operations of the Bourg, Louisiana
and Mermentau, Louisiana landfarms purchased by the Company as part of the
Campbell Wells Acquisition. As part of the Campbell Wells Acquisition, Sanifill
(a wholly-owned subsidiary of USA Waste) agreed to retain responsibility for the
contingent liabilities associated with each of these lawsuits. Sanifill also
agreed in the Campbell Wells Acquisition to indemnify the Company from and
against, among other things, the contingent liabilities associated with these
lawsuits. The obligation of Sanifill to indemnify the Company is limited to $10
million.

     In one of the lawsuits filed against Campbell Wells, approximately 300
individuals residing in and around Grand Bois, Louisiana are seeking unspecified
monetary damages allegedly suffered as a result of (i) odors allegedly emitted
by oilfield waste received from Exxon Company U.S.A. ("Exxon") at the landfarm
in March 1994, and (ii) alleged air, water and soil contamination in connection
with ongoing operations at the landfarm. Trial in this matter on the claims of
ten plaintiffs is set to commence in the 17th Judicial District Court for the
Parish of Lafourche, Louisiana on July 13, 1998. A second lawsuit, brought by
one individual, seeks unspecified monetary damages allegedly suffered as a
result of odors allegedly emitted by oilfield waste received from Exxon at the
landfarm in March 1994. This lawsuit is also pending in the 17th Judicial
District Court for the Parish of Lafourche, Louisiana and trial is set to
commence on July 13, 1998. A third lawsuit, filed as a class action in the Civil
District Court for the Parish of Orleans, Louisiana, seeks unspecified monetary
damages allegedly suffered as a result of alleged air, water and soil
contamination in connection with ongoing operations at the Mermentau, Louisiana
landfarm. No trial date has been set for this matter. In a fourth lawsuit, six
individuals filed suit on March 7, 1996 against Campbell Wells in the 17th
Judicial District Court for the Parish of Lafourche, Louisiana seeking
preliminary and permanent injunctive relief against certain treatment operations
conducted at the Bourg, Louisiana landfarm which the plaintiffs contend have
resulted and will result in adverse health effects by way of emissions of
alleged air pollutants. The plaintiffs' request for a preliminary injunction was
heard during the summer of 1996. On December 30, 1996, the court entered an
order granting in part and denying in part the relief requested by the
plaintiffs. Specifically, the court found that there was no evidence that
emissions resulting from the treatment operations equalled or exceeded any
relevant safety standard, health standard or occupational standard and,
therefore, denied the plaintiffs' request for a temporary injunction prohibiting
such treatment operations. The court did, however, preliminarily enjoin Campbell
Wells (and, thus, indirectly the Company) from treating oilfield waste received
from Exxon in March 1994 in one particular treatment cell located within 500
feet of a building in which one of the plaintiffs resides. In connection
therewith, the court ordered that the Commissioner of the Louisiana Department
of Conservation be made a party to the litigation and substituted for the
plaintiffs on the limited issue of whether Campbell Wells has violated the
location criteria for the particular treatment cell involved. No trial date has
been set for the plaintiffs' request for permanent injunctive relief; however,
based upon the court's rulings from the preliminary injunction trial and initial
discussions with the Louisiana Department of Conservation, the

                                       37
<PAGE>
Company believes that any permanent injunctive relief that might be entered will
not have a material adverse effect upon the Company's operations at the Bourg
landfarm.

     In January 1998, the Company was named as a defendant in two of the
lawsuits arising out of the operations of the Bourg landfarm (i.e. the lawsuit
seeking injunctive relief and the lawsuit brought by the approximately 300
individuals residing in and around Grand Bois, Louisiana). The Company has not
yet been named as a defendant in the remaining lawsuit arising out of the
operations of the Bourg landfarm or the class action arising out of the
operations of the Mermentau landfarm; however, there can be no assurance that
the Company will not subsequently be named as a defendant in these lawsuits as
well.

     The Company believes that the ultimate disposition of the above-referenced
lawsuits will not have a material adverse effect on the Company's business,
results of operations or financial condition. This belief is based upon, among
other things, the following reasons: (i) Sanifill has agreed to retain
responsibility for the contingent liabilities associated with these lawsuits,
(ii) Sanifill has agreed to indemnify the Company against such contingent
liabilities up to a maximum of $10 million, (iii) the Company has been operating
the Bourg and Mermentau landfarms only since December 1996, approximately four
months after the last of the three lawsuits seeking monetary damages was
originally filed, and (iv) the results of air, water and soil testing conducted
in and around the Bourg landfarm by the Louisiana Department of Health and
Hospitals, the Louisiana Department of Natural Resources and the Louisiana
Department of Environmental Quality indicate that the Company's operations at
the landfarms are in compliance with all applicable rules and regulations. There
can be no assurance, however, that a judgment will not ultimately be entered
against the Company in one or more of these lawsuits. In the event a monetary
judgment is entered against the Company, Sanifill is not required or is unable
to completely indemnify the Company against such judgment and the judgment is
not covered by insurance, such a judgment could have a material adverse effect
on the Company's business, results of operations and financial condition. In
addition, notwithstanding any indemnification to be provided by Sanifill, an
adverse ruling against the Company in the lawsuit seeking injunctive relief
could have a material adverse effect on the Company's operations at the Bourg
landfarm (which operations contributed 3.1% of the Company's pro forma revenues
for the year ended December 31, 1997 and 1.1% of the Company's pro forma
revenues for the first three months of 1998) and, therefore, the Company's
business, results of operations and financial condition.

     In February 1997, an action entitled JUDY GARCIA, ET AL. V. RE-CLAIM
ENVIRONMENTAL was filed in the 51st Judicial District Court of Harris County,
Texas. This action was brought by the residents of an apartment complex located
adjacent to one of the Company's processing facilities and alleges that the
Company is guilty of nuisance, trespass, negligence and gross negligence by
reason of its pollution of the air, soil and ground and surface water and the
release of noxious odors. The plaintiffs have requested unspecified monetary
damages. The Company denies liability and intends to vigorously defend this
action.

     The Company is, from time to time, a party to litigation arising in the
normal course of its business, most of which involves claims for personal injury
or property damage incurred in connection with its operations. Except as
described above, the Company is not currently involved in any litigation that it
believes will have a material adverse effect on its business, results of
operations or financial condition.

EMPLOYEES

     At May 1, 1998, the Company employed approximately 690 persons full-time.
Neither the Company nor any of its subsidiaries is a party to any collective
bargaining agreement covering its employees. The Company believes that its
relationships with its employees are satisfactory.

BOARD OF DIRECTORS

     The Company's Certificate of Incorporation provides for the Board of
Directors to be divided into three classes, with staggered three-year terms. As
a result, only one class of directors is elected at each annual meeting of
stockholders of the Company, with the other classes continuing for the remainder
of their respective three-year terms, and directors may be removed from office
only for cause. This classification of the Board of Directors may make it more
difficult for the Company's existing stockholders to replace the Board of
Directors as well as for another party to obtain control of the Company by
replacing the Board of Directors. See "Risk Factors -- Potential Anti-Takeover
Effect of Certain Charter Provisions."

     The Board of Directors has an Audit Committee and a Compensation Committee.
The members of both the Audit Committee and the Compensation Committee are
Messrs. McEneaney, Rothrock and Tyler. The principal duties of the Audit
Committee are to recommend to the Board of Directors the selection of the
Company's independent accountants, discuss and review with the Company's
independent accountants the audit plan, the auditor's report and management
letter and the Company's accounting policies, and review the accounting
procedures and internal control procedures recommended by the Company's
independent accountants. The principal duties of the Compensation Committee are
to establish and review the objectives, structure, cost and administration of
the Company's major compensation and benefit policies and programs, review
annually officers' and key employees' salaries, management incentives and stock
options, and administer the Company's stock option plan, management incentive
plans and other long-term incentive plans.

     During 1997, each of the Company's directors attended at least 75% of the
aggregate of (i) the total number of meetings of the Board of Directors, and
(ii) the total number of meetings held by all committees of the Board on which
he served.

     In connection with the acquisition of his three companies in June 1997, the
Company caused Mr. Blanton to be appointed to the Board of Directors of the
Company. In addition, for as long as Mr. Blanton is the beneficial owner of at
least 5% of the outstanding Common Stock, the Company is obligated to nominate
Mr. Blanton for election to the Company's Board of Directors and Messrs. Orr,
Blackwell and William M. DeArman are obligated to vote all of the shares of
Common Stock controlled by them in favor of Mr. Blanton's election to the Board
of Directors.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     During 1997, Messrs. McEneaney, Rothrock and Tyler served on the Company's
Compensation Committee. Since 1990, Mr. Rothrock has served as the Vice
President -- Business Development for Sanifill and, subsequently, USA Waste. In
December 1997, the Company paid the outstanding balance (approximately $22.6
million) of the promissory note issued by the Company to Sanifill in the
Campbell Wells Acquisition. In May 1998, the Company acquired three additional
businesses from USA Waste. See "Certain Transactions -- Other." The Company
does not believe that Mr. Rothrock had a direct or indirect material interest in
any of these acquisitions.

EXECUTIVE COMPENSATION

     The following table sets forth certain information with respect to the
compensation of the Company's executive officers during 1996 and 1997. The
Company was incorporated in November 1996. Messrs. Orr and Blackwell were the
only executive officers who received any compensation from the Company in 1996.

OPTIONS GRANTED; OPTION EXERCISES AND FISCAL YEAR-END VALUES

     During 1997, Mr. Lawlor was granted an option to purchase 300,000 shares of
Common Stock at a price of $9.50 per share. These options, which vest at a rate
of 33 1/3% per year commencing on June 19, 1998 and expire on August 19, 2007,
constituted 57% of the total options granted to employees of the Company in
1997. The potential realized values of Mr. Lawlor's options at assumed annual
rates of stock price appreciation of 5% and 10% over the term of the options are
$2,248,917 and $3,598,818, respectively. The value of Mr. Lawlor's options as of
December 31, 1997 was approximately $1,387,500. Neither Mr. Orr nor Mr.
Blackwell has ever been granted a stock option by the Company.

EMPLOYMENT AGREEMENTS; CHANGES IN CONTROL

     Each of Messrs. Lawlor, Orr and Blackwell has entered into an employment
agreement with the Company providing for an annual base salary of $175,000,
$150,000 and $120,000, respectively, with the right to receive incentive
compensation at the discretion of the Board of Directors. Each employment
agreement is for a term of five years with the term to be extended an additional
one year on each anniversary date of the employment agreement, unless either
party gives notice that the term of the employment agreement should not be so
extended. If the employee's employment is terminated by the Company without
cause, then the employee will continue to receive his base salary and employee
benefits for the remainder of the term of his employment agreement. If his
employment is terminated by the Company with cause, then the employee will not
be entitled to earn any further compensation or benefits under his employment
agreement. If the Company undergoes a "change in control", then, under certain

                                       41
<PAGE>
circumstances, the employee will have the right to require the Company to pay to
him a lump sum amount equal to approximately three times his "base amount", as
defined in Section 280G of the Internal Revenue Code. This base amount is
generally equal to the average annual gross income of the employee for the five
taxable years ending before the date on which the change in control occurs. This
payment will be in lieu of any further compensation or benefits payable to the
employee under the employment agreement. The employment agreement also contains
a covenant by the employee not to compete with the Company at any time during
his employment and for a period of two years after the termination of his
employment, except for a termination subsequent to a change in control.

STOCK OPTION PLANS

  1996 INCENTIVE STOCK OPTION PLAN
     On November 20, 1996, the Board of Directors adopted the U S Liquids Inc.
1996 Incentive Stock Option Plan. Thereafter, in June 1997, the Board of
Directors adopted various amendments to this plan, and the amended plan (the
"Stock Option Plan") was approved by the stockholders of the Company. The
purpose of the Stock Option Plan is to promote the long-term growth and
profitability of the Company and the value of the Common Stock by providing
selected employees and consultants of the Company (including directors who are
also employees) with incentives to contribute to the success of the Company. The
number of shares of Common Stock issuable under the Stock Option Plan is
automatically adjusted on the first day of each fiscal year to an amount equal
to 15% of the total number of shares of Common Stock which are outstanding on
such date, provided that the number of shares issuable under the Stock Option
Plan will not be less than 1,500,000 shares or exceed 3,000,000 shares.
     The Stock Option Plan is required to be administered by a committee
designated by the Board of Directors. The committee must consist of at least two
Non-Employee Directors, as that term is defined in Rule 16b-3 under the Exchange
Act, or, at the discretion of the Board of Directors in order to comply with the
requirements of Rule 16b-3, the committee may consist of the entire Board of
Directors. Currently, the committee consists of Messrs. McEneaney, Rothrock and
Tyler. In awarding options under the Stock Option Plan, the committee considers
various factors, such as the past and expected future performance of an employee
and the extent to which an employee has been compensated for his or her
performance. The committee has not established any fixed formula for awarding
options under the Stock Option Plan. The exercise price for options issued under
the Stock Option Plan must, in the case of incentive stock options, be at least
equal to the fair market value of the Common Stock subject to the option at the
time the option is granted, and in the case of nonqualified stock options, be at
least equal to 75% of the fair market value of the shares subject to the option
at the time it is granted. In the case of an incentive stock option granted to
an employee who holds more than 10% of the Common Stock of the Company, the
exercise price must be at least 110% of the fair market value of the shares
subject to the option at the time it is granted. Options for a total of 802,875
shares of Common Stock are outstanding under the Stock Option Plan at exercise
prices ranging from $.02 per share to $20.25 per share.

  DIRECTORS' STOCK OPTION PLAN
     The Board of Directors adopted the U S Liquids Inc. Directors' Stock Option
Plan (the "Directors' Plan") and the stockholders approved the Directors' Plan
in June 1997. The Directors' Plan is intended to further the interests of the
Company by providing recognition and compensation to its outside directors for
their time, effort and participation in the growth and protection of the
Company's business. The Directors' Plan provides that, at the time of his or her
initial election or appointment to the Board, each director who is not an
employee of the Company and has not been an employee of the Company during the
preceding 12 months will automatically be granted an option to purchase 10,000
shares of Common Stock. In addition, each outside director will automatically be
granted an option to purchase 5,000 shares of Common Stock on January 1 of each
calendar year. The exercise price of all options granted under the Directors'
Plan must be equal to the fair market value of the Common Stock at the time the
option is granted. Options for a total of 35,000 shares of Common Stock at
exercise prices ranging from $9.50 per share to $16.00 per share have been
granted under the Directors' Plan.
     The Directors' Plan is administered by the Compensation Committee. The
Compensation Committee is required to administer the Directors' Plan in strict
accordance with its terms and does not have the discretion to vary, add to or
take from the terms of the Directors' Plan.

                              CERTAIN TRANSACTIONS

CAMPBELL WELLS ACQUISITION

     On December 13, 1996, the Campbell Wells Acquisition was consummated. The
assets acquired in the Campbell Wells Acquisition included four oilfield waste
processing facilities in Louisiana, one oilfield waste processing facility in
Texas, all equipment and capital improvements related to the processing
facilities, and approximately $8.1 million of working capital. In consideration
for these assets, the Company issued to Sanifill, a wholly-owned subsidiary of
USA Waste, a $27.8 million promissory note (the "Sanifill Note") and a
transferable 10-year warrant for the purchase of one million shares of Common
Stock at an exercise price of $2.00 per share (the "Sanifill Warrant"). In
December 1997, the Company paid the Sanifill Note in full.

     In connection with the Campbell Wells Acquisition, Sanifill assigned to the
Company its rights and obligations under the Disposal Agreement. Pursuant to the
terms of the Disposal Agreement, through June 30, 2021, Newpark is obligated to
deliver to the Company on an annual basis for processing and disposal at certain
of its Louisiana landfarms the lesser of (i) one-third of the barrels of
oilfield waste that Newpark receives for processing and disposal in the
Territory and (ii) 1,850,000 barrels of oilfield waste, in each case excluding
saltwater. During the twelve-month period ending December 31, 1997, Newpark
delivered approximately 1,430,000 barrels of oilfield waste, excluding
saltwater, to the Company's landfarms.

     The Disposal Agreement governs the price to be paid by Newpark to the
Company for delivered oilfield waste. Currently, Newpark is paying to the
Company $5.50 for each barrel of oilfield waste delivered to the Company under
the Disposal Agreement. This contractual price is lower than the $6.56 average
per barrel price (excluding saltwater) that the Company received from other
customers during the first quarter of 1998, and the Company expects such price
disparity to persist for the duration of the Disposal Agreement; however,
Newpark's delivery obligations under the Disposal Agreement allow the Company to
eliminate virtually all marketing and transfer expenses on waste delivered by
Newpark. On June 30, 1998 and on each subsequent December 31st and June 30th
occurring during the term of the Disposal Agreement, the per barrel price to be
paid by Newpark to the Company will be adjusted. Adjustments are made based upon
changes occurring in the average prices received by Newpark from customers for
oilfield waste processing and disposal and other related services performed by
Newpark during the six-month period ending on the applicable adjustment date
compared, on a percentage basis, to the average prices received by Newpark from
customers for such disposal and services during the six-month period commencing
12 months prior to such adjustment date and concluding six months prior to such
adjustment date. The adjusted price will be applied retroactively to all
invoices received by Newpark from the Company during the six-month period
preceding the applicable adjustment date. In no event, however, will the price
paid by Newpark to the Company be less than $5.50 per barrel. The Company does
not presently believe that this adjustment mechanism will in the near future
result in a material increase in the price per barrel paid by Newpark.

     As part of the Campbell Wells Acquisition, Sanifill agreed that if, prior
to December 31, 1999, the Company is required by the Louisiana Department of
Natural Resources or the Louisiana Department of Environmental Quality to
construct or install additional water injection wells with respect to certain of
the Louisiana landfarms purchased by the Company from Sanifill, Sanifill will
reimburse the Company for up to $1.6 million of expenses incurred by the Company
in constructing or installing the additional water injection wells. Excepting
this reimbursement obligation and certain amounts previously paid by Sanifill to
reimburse the Company for closure and post-closure requirements associated with
the Lacassine, Louisiana NORM facility, the Company assumed all liabilities and
obligations of Campbell Wells for closure, post-closure, monitoring,
maintenance, environmental remediation and clean-up of all landfarms and
treatment sites owned, occupied, leased or operated by Campbell Wells as of the
date of the Campbell Wells Acquisition.

     In connection with the Campbell Wells Acquisition, Sanifill also agreed to
indemnify the Company against all liabilities of Sanifill and Campbell Wells not
expressly assumed by the Company and, subject to certain limitations, against
any breach of any agreement or covenant made by Sanifill in the definitive
acquisition agreement. To be eligible for indemnification by Sanifill, an
individual claim or loss by the Company based on a Sanifill breach must exceed
$10,000, and all such claims and losses must have exceeded $200,000, in which
case the indemnification obligation of Sanifill is limited to the amount of such

                                       43
<PAGE>
claims and losses in excess of $200,000. Further, the obligation of Sanifill to
indemnify the Company is limited to $10 million.

     In connection with the Campbell Wells Acquisition, the Company and Sanifill
executed noncompetition agreements under which each party agreed not to compete
with the other in certain businesses for a period of five years. In its
noncompetition agreement, Sanifill agreed not to engage in the collection,
transfer, transportation, treatment or disposal of oilfield waste during the
restricted period. In return, the Company agreed not to engage in the
collection, treatment or disposal of municipal solid wastes, construction debris
or demolition debris during the restricted period, or own any interest in any
company engaged in any such business. In addition, as a result of the Campbell
Wells Acquisition, the Company is prohibited until August 2001 from (i)
accepting from any customer other than Newpark oilfield waste generated in a
marine environment or transported in a marine vessel within the Territory, and
(ii) engaging in the site remediation and closure business in the Territory.

     On September 3, 1997, the Company filed a shelf registration statement
under Rule 415 of the Securities Act registering, among other things, the shares
of Common Stock issuable upon exercise of the Sanifill Warrant. The Company has
agreed to keep this shelf registration statement continuously effective until
the earlier of three years after the date of final exercise of the Sanifill
Warrant and such time as the holder of the Sanifill Warrant has sold all of the
shares issuable upon exercise thereof. However, without the Company's prior
consent, and, under certain circumstances, the prior consent of one of the lead
underwriters of the IPO, the number of shares offered by Sanifill pursuant to
this registration statement in any calendar year cannot exceed the following
limitations:

                                        MAXIMUM NUMBER OF
                                          SHARES TO BE
                YEAR                         OFFERED
1998.................................        200,000
1999.................................        200,000
2000.................................        250,000
2001-2006............................        300,000

     The Sanifill Warrant also grants its holder the "piggyback" registration
right to include shares of Common Stock purchased upon exercise of the Sanifill
Warrant in the coverage of any registration statement under the Securities Act
filed by the Company with respect to an offering of Common Stock by the Company
for its own account or for the account of any of its securities holders.
Sanifill has waived its right to have any shares registered for resale in
connection with this offering.

OTHER

     On June 17, 1997, the Company acquired all of the outstanding stock of
three companies owned by Thomas B. Blanton, a director and employee of the
Company. Mr. Blanton received 1,062,500 shares of Common Stock in exchange for
his capital stock of these companies. Pursuant to the terms of the acquisition
agreements, Mr. Blanton became a director and employee of the Company. In
addition, pursuant to the terms of the acquisition agreements, the Company used
approximately $1.2 million of the net proceeds of the IPO to repay various debts
of Mr. Blanton's former companies, all of which had been personally guaranteed
by Mr. Blanton and of which approximately $200,000 was owed to Tommy Yount, the
brother-in-law of Mr. Blanton.

     The Company regularly purchases used cooking oil and other food processing
residuals that Mr. Yount collects from generators of such materials. During
1997, the Company purchased approximately $243,000 of such materials from Mr.
Yount.

     In connection with the organization of the Company in November 1996,
Messrs. Orr, Blackwell and William M. DeArman, who may be deemed to be promoters
of the Company, purchased (together with members of their immediate family or
entities controlled by them) 976,000, 375,000 and 500,000 shares of Common Stock
for $19,520, $7,500 and $10,000, respectively. In December 1996, Mr. DeArman
purchased an additional 50,000 shares of Common Stock for $87,500.

     On May 7, 1998, the Company entered into definitive agreements to acquire
from USA Waste all of the outstanding capital stock of Northern A-1 Services,
Inc. and substantially all of the assets of City Environmental, Inc. and
Universal Waste and Transit for $13.7 million, $30.8 million and $2.7 million in
cash and assumed debt, respectively. USA Waste is the parent corporation of
Sanifill, a principal stockholder of the Company.

                           DESCRIPTION OF SECURITIES

COMMON STOCK

     The Company is authorized to issue 30,000,000 shares of Common Stock, of
which 8,516,211 shares are outstanding. Holders of Common Stock are entitled to
one vote for each share held on all matters submitted to a vote of stockholders.
There is no cumulative voting with respect to the election of directors. See
"Risk Factors -- Concentration of Voting Control." Holders of Common Stock are
entitled to receive ratably any dividends that may be declared by the Board of
Directors of the Company out of legally available funds. Upon the liquidation,
dissolution or winding up of the Company, the holders of Common Stock are
entitled to receive ratably the net assets of the Company after payment of all
debts and liabilities and liquidation preferences of any outstanding shares of
Preferred Stock. Holders of Common Stock have no preemptive, subscription,
redemption or conversion rights. As of May 6, 1998, the Company had 293 holders
of record of Common Stock.

PREFERRED STOCK

     The Company's Certificate of Incorporation authorizes the issuance of
5,000,000 shares of Preferred Stock, of which no shares are outstanding. Shares
of unissued Preferred Stock may be issued in one or more series from time to
time with such designations, rights, preferences and limitations as the Board of
Directors may determine. The rights, preferences and limitations of separate
series of Preferred Stock may differ with respect to such matters as may be
determined by the Board of Directors including, without limitation, the rate of
dividends, method or nature of payment of dividends, terms of redemption,
amounts payable on liquidation, sinking fund provisions, conversion rights and
voting rights. Such undesignated shares could also be used as an anti-takeover
device by the Company. For example, they could be issued with "super-voting
rights" and placed in the control of parties friendly to the current
management.

OPTIONS AND WARRANTS

     The Company has outstanding options to purchase an aggregate of 1,181,625
shares of Common Stock, of which 281,250 shares are issuable pursuant to options
the vesting of which are contingent upon the successful completion of certain
corporate business development activities. The Company has outstanding warrants
to purchase an additional 1,235,000 shares of Common Stock consisting of (i) the
Sanifill Warrant for 1,000,000 shares at $2.00 per share; (ii) warrants for
112,500 total shares at $11.40 per share issued to Sanders Morris Mundy Inc.
("SMM") and Van Kasper & Company in connection with the IPO (the "IPO
Warrants"); (iii) a warrant for 37,500 shares at $9.50 per share issued to SMM
for certain consulting services (the "SMM Warrant"); and (iv) other warrants
for 85,000 total shares at exercise prices ranging from $9.50 per share to
$14.125 per share.

SHARES ELIGIBLE FOR FUTURE SALE

     As of the date of this Prospectus, the Company had issued and outstanding
8,516,211 shares of Common Stock. There are over 5,500,000 shares of Common
Stock which are freely tradeable or which are currently eligible for resale
under Rules 144 and 145 promulgated under the Securities Act. Further, the
Company has issued and outstanding options to purchase up to 1,181,625 shares of
Common Stock and warrants to purchase up to 1,235,000 shares of Common Stock.
Additional shares of Common Stock may become eligible for sale on the public
market from time to time upon exercise of warrants and stock options.

     The Company has filed a registration statement on Form S-8 to register all
shares subject to the Stock Option Plan and the Directors' Plan. The Company has
also filed a shelf registration statement on Form S-1 registering for resale
388,397 total shares of Common Stock held by Messrs. Orr, Blackwell, DeArman and
certain owners of a business acquired by the Company in June 1997 and the
1,000,000 shares of Common Stock underlying the Sanifill Warrant, and 1,682,901
shares of Common Stock remaining available for use in acquisitions by the
Company. The Company has also agreed to register for resale all shares of Common
Stock issuable upon the exercise of the IPO Warrants and the SMM Warrant and
168,987 shares issued in connection with a 1997 acquisition.

     No prediction can be made as to the effect, if any, the sale of shares or
the availability of shares for sale will have on the market price for the Common
Stock prevailing from time to time. Nevertheless, sales, or the availability for
sale of, substantial amounts of the Common Stock in the public market could
adversely

                                       46
<PAGE>
affect prevailing market prices and the future ability of the Company to raise
equity capital and complete any additional acquisitions for Common Stock.

DELAWARE LAW AND CERTAIN CHARTER PROVISIONS
     The Company's Certificate of Incorporation limits, to the fullest extent
permitted by Delaware law, the liability of a director to the Company or its
stockholders for monetary damages for a breach of such director's fiduciary duty
as a director. Delaware law presently permits such limitations of a director's
liability except where a director breaches his or her duty of loyalty to the
Company or its stockholders, fails to act in good faith or engages in
intentional misconduct or a knowing violation of law, authorizes payment of an
unlawful dividend or stock repurchase, or obtains an improper personal benefit.
This provision is intended to afford directors additional protection, and limit
their potential liability, from suits alleging a breach of the duty of care by a
director. The Company believes this provision will assist it in maintaining and
securing the services of directors who are not employees of the Company. As a
result of the inclusion of such a provision, stockholders may be unable to
recover, under Delaware law, monetary damages against directors for actions
taken by them that constitute negligence or gross negligence or that are in
violation of their fiduciary duties, although it may be possible to obtain
injunctive or other equitable relief with respect to such actions. If equitable
remedies are found not to be available to stockholders for any particular case,
stockholders may not have any effective remedy, under Delaware law, against the
challenged conduct.
     The Company's Certificate of Incorporation also provides that directors and
officers shall be indemnified against liabilities arising from their service as
directors or officers to the fullest extent permitted by law, which generally
requires that the individual act in good faith and in a manner he or she
reasonably believes to be in or not opposed to the Company's best interests. The
Company has obtained directors and officers liability insurance to limit its
exposure under these provisions.
     Under the Company's Certificate of Incorporation, the Board of Directors is
divided into three classes of directors with each class serving a staggered
three-year term. The classification system of electing directors may tend to
discourage a third party from making a tender offer or otherwise attempting to
obtain control of the Company and may maintain the incumbency of the Board of
Directors, as it generally makes it more difficult for stockholders to replace a
majority of the directors. See "Risk Factors -- Potential Anti-Takeover Effect
of Charter Provisions."

                                           =========

     The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase and accept delivery of the shares of Common Stock

     The Underwriters initially propose to offer the shares of Common Stock in
part directly to the public at the offering price set forth on the cover page of
this Prospectus and in part to certain dealers (including the Underwriters) at
such price less a concession not in excess of $     per share. The Underwriters
may allow, and such dealers may re-allow, to certain other dealers a concession
not in excess of $     per share. After the offering of the Common Stock, the
offering price and other selling terms may be changed by the Representatives at
any time without notice.

     The Company has granted to the Underwriters an option, exercisable within
30 days after the date of this Prospectus, to purchase, from time to time, in
whole or in part, up to an aggregate of 562,500 additional shares of Common
Stock at the public offering price less underwriting discounts and commissions.
The Underwriters may exercise such option solely to cover overallotments, if
any, made in connection with the offering. To the extent that the Underwriters
exercise such option, each Underwriter will become obligated, subject to certain
conditions, to purchase its pro rata portion of such additional shares based on
such Underwriter's percentage underwriting commitment as indicated in the
preceding table.

     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that the Underwriters may be required to make in respect thereof.

     Each of the Company, its executive officers and directors and certain
stockholders of the Company has agreed, subject to certain exceptions, not to
(i) offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase or otherwise transfer or dispose of, directly or indirectly,
any shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock or (ii) enter into any swap or other arrangement
that transfers all or a portion of the economic consequences associated with the
ownership of any Common Stock (regardless of whether any of the transactions
described in clause (i) or (ii) is to be settled by the delivery of Common
Stock, or such other securities, in cash or otherwise) for a period of 120 days
after the date of this Prospectus without the prior written consent of DLJ. In
addition, during such period, the Company has also agreed not to file any
registration statement with respect to, and each of its executive officers,
directors and certain stockholders of the Company has agreed not to make any
demand for, or exercise any right with respect to, the registration of any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock without DLJ's prior written consent.

developing and implementing its acquisition program. As consideration for its
services, the Company issued the SMM Warrant to SMM. In connection with the IPO,
the Company issued the IPO Warrant to Van Kasper & Company and SMM.

stock as reported on the AMEX was $25 per share. See "Price Range of Common
Stock and Dividend Policy."

the Underwriters that would permit a public offering of the shares of Common
Stock offered hereby in any jurisdiction where action for that purpose is
required. The shares of Common Stock offered hereby may not be offered or sold,
directly or indirectly, nor may this Prospectus or any other offering material
or advertisements in connection with the offer and sale of any such shares of
Common Stock be distributed or published in any jurisdiction, except under

Common Stock. Specifically, the Underwriters may overallot the offering,

maintain the market price of the Common Stock above independent market levels.
The Underwriters are not required to engage in these activities, and may end any
of these activities at any time.

                                U S LIQUIDS INC.
            INTRODUCTION TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS

     The following unaudited pro forma financial statements present the balance
sheet and income statement data from the consolidated financial statements of U
S Liquids Inc. (U S Liquids or the Company) combined with the historical
financial data of acquisitions by the Company since its initial public offering
(the Acquisitions) as follows: (i) the unaudited pro forma balance sheet
includes the historical consolidated balance sheet data of U S Liquids at March
31, 1998 combined with the Acquisitions consummated or to be consummated after
March 31, 1998 as if each had occurred on March 31, 1998 and (ii) the unaudited
pro forma income statements for the year ended December 31, 1997 and for the
three months ended March 31, 1997 and 1998 include the historical consolidated
income statements of U S Liquids for the respective periods combined with all
Acquisitions consummated or to be consummated since the Company's initial public
offering as if each had occurred January 1, 1997. Additionally, the effects of
the Company's initial public offering and the Company's current public equity
offering (the Offering) are included in the unaudited pro forma financial
statements as if they had occurred on January 1, 1997. The income statement data
present depreciation and amortization expenses separately from operating
expenses and selling, general and administrative expenses. Depreciation and
amortization expenses are included in the operating and the selling, general and
administrative expense captions set forth in the audited financial statements.

     The Company has preliminarily analyzed the savings that it expects to be
realized by consolidating certain operational and general and administrative
functions. The Company cannot quantify these savings due to the short period of
time since the closing of the majority of the Acquisitions. It is anticipated
that these savings will be partially offset by the incremental increase in costs
related to the Company's corporate management. However, these costs, like the
savings that they offset, cannot be quantified accurately. Neither the
anticipated savings nor the anticipated costs have been included in the pro
forma financial statements.

     The pro forma financial statements include certain adjustments to the
historical financial statements of the Acquisitions, including the adjustment of
depreciation and amortization expenses to reflect purchase price allocations,
recording of interest expense to reflect debt issued in connection with the
Acquisitions, and certain reductions of salaries and benefits payable to the
previous owners of the businesses acquired which were agreed to in connection
with the Acquisitions and the related income tax effects of these adjustments.

     The pro forma adjustments are based on preliminary estimates, available
information and certain assumptions and may be revised as additional information
becomes available. The pro forma financial statements do not purport to
represent what the Company's financial position or results of operations would
actually have been if such transactions in fact had occurred on those dates or
project the Company's financial position or results of operations for any future
period. Since the Company and the Acquisitions were not under common control or
management for all periods, historical combined results may not be comparable
to, or indicative of, future performance. The unaudited pro forma financial
statements should be read in conjunction with the other financial statements and
notes thereto included elsewhere in this Prospectus, as well as information
included under the headings "Selected Financial Data," "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Risk Factors" included elsewhere herein.

                  NOTES TO PRO FORMA BALANCE SHEET (UNAUDITED)

(a)  These adjustments reflect the purchase of the Acquisitions that were
     consummated or will be consummated subsequent to March 31, 1998, including
     approximately $61,363,000 of long-term obligations issued for the cash
     portion of the purchase price and for certain debt obligations paid upon
     acquisition and approximately 1,017,000 shares issued. These adjustments
     also reflect purchase price allocations on the Acquisitions, including
     allocating the deferred income tax liability attributable to the temporary
     differences between the financial reporting and income tax bases on assets
     and liabilities previously held as S Corporations and adjusting working
     capital to zero for certain Acquisitions through the collection and
     subsequent repayment of approximately $6,500,000 in accounts receivable.

(b)  Reflects the proceeds from the issuance of 3,750,000 shares of Common
     Stock, net of estimated offering costs. Offering costs primarily consist of
     underwriting discounts and commissions, accounting fees, legal fees and
     printing expenses.

(c)  Reflects the repayment of certain debt obligations with proceeds from the
     Offering.

      the Acquisitions previously taxed as S corporations or limited liability
      companies as well as federal and state income taxes relating to the pro

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To U S Liquids Inc.:

     We have audited the accompanying consolidated balance sheets of U S Liquids
Inc. (a Delaware corporation) and subsidiaries as of December 31, 1996 and 1997,
and the related consolidated statements of income, stockholders' equity and cash
flows for each of the three years in the period ended December 31, 1997. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
U S Liquids Inc. and subsidiaries as of December 31, 1996 and 1997, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  BUSINESS AND ORGANIZATION:

     U S Liquids Inc. and subsidiaries (collectively "U S Liquids"or the
"Company") was founded November 18, 1996, and is a leading provider of
services for the collection, processing, disposal and recovery of liquid waste
in North America. On December 13, 1996, the Company acquired its Oilfield Waste
Division from Campbell Wells, L.P. and Campbell Wells NORM, L.P. (referred to as
"Campbell Wells" or "the Predecessor" to the extent of the operations so
acquired) which were wholly owned subsidiaries of Sanifill, Inc. ("Sanifill").
The Oilfield Waste Division treats and disposes of oilfield waste generated in
oil and gas exploration and production. In June 1997, the Company formed the
basis of its Liquid Waste Division by acquiring Mesa Processing, Inc., T&T
Grease Services, Inc. and Phoenix Fats & Oils, Inc. ("Mesa") and American
WasteWater ("AWW"). Each of these acquisitions was accounted for under the
pooling-of-interests method of accounting. The Liquid Waste Division collects,
processes and disposes of liquid waste and recovers by-products from these waste
streams.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  BASIS OF PRESENTATION

     The consolidated financial statements include the accounts of the Company,
after elimination of all significant intercompany accounts and transactions. The
consolidated financial statements for 1997 represent the operations of the
Company, including combined revenues and net income of Mesa and AWW for the
pre-acquisition period in 1997 of $7,291,000 and $539,000 respectively, as well
as all other acquired companies' operations from their respective dates of
acquisition.

  INTERIM FINANCIAL INFORMATION

     The interim consolidated financial statements as of March 31, 1998, and for
the three months ended March 31, 1997 and 1998, are unaudited, and certain
information and footnote disclosures, normally included in financial statements
prepared in accordance with generally accepted accounting principles, have been
omitted. In the opinion of management, all adjustments, consisting only of
normal recurring adjustments, necessary to fairly present the financial
position, results of operations and cash flows with respect to the interim
consolidated financial statements, have been included. The results of operations
for the interim periods are not necessarily indicative of the results for the
entire fiscal year.

  USE OF ESTIMATES

     The preparation of financial statements requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

  CASH AND CASH EQUIVALENTS

     All highly liquid investments with an original maturity of three months or
less are classified as cash equivalents.

  CONCENTRATIONS OF CREDIT RISK

     Accounts receivable potentially subject the Company to concentrations of
credit risk. At December 31, 1996, 41 percent and 16 percent, respectively, of
total accounts receivable were associated with two customers. At December 31,
1997, 13 percent of total accounts receivable was associated with one customer.
In addition, sales to one customer represented 62 percent and 43 percent of
total revenues for the years ended December 31, 1995, and 1996, respectively.
Sales to two customers represented 22 percent and 17 percent, respectively, of
total revenues for the year ended December 31, 1997.

<PAGE>
                                U S LIQUIDS INC.
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The Company's customers are concentrated in the oil and gas industry in
Louisiana and Texas, the liquid waste collection business in Louisiana and Texas
and the chemical processing and livestock feed industries in Mexico. Total sales
to customers in Mexico represented 82 percent, 70 percent and 31 percent of
total revenues for the years ended December 31, 1995, 1996 and 1997,
respectively. Accounts receivable from customers in Mexico represented
approximately 9 percent and 20 percent of total accounts receivable at December
31, 1996 and 1997, respectively. Management performs ongoing credit analyses of
the accounts of its customers and provides allowances as deemed necessary.
Additionally, sales are dollar-denominated and the majority of international
sales are secured by letters of credit.

  INVENTORIES

     Inventories are stated at the lower of cost or market and, at December 31,
1996 and 1997, consisted of finished grease products of $265,000 and $435,000,
respectively, and unprocessed grease of $74,000 and $132,000, respectively. Cost
is determined using the first-in, first-out (FIFO) method.

  PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment are recorded at cost. Improvements or
betterments which significantly extend the life of an asset are capitalized.
Expenditures for maintenance and repair costs are charged to operations as
incurred. The cost of assets retired or otherwise disposed of and the related
accumulated depreciation are eliminated from the accounts in the year of
disposal. Gains and losses resulting from property disposals are included in
other income or expense. Depreciation is computed using the straight-line
method.

  LONG-LIVED ASSETS

     Long-lived assets consist primarily of the excess of cost over net assets
of acquired businesses (goodwill) and disposal sites. Management continually
evaluates whether events or circumstances have occurred that indicate the
remaining estimated useful life of intangible assets and other long lived assets
may warrant revision or that remaining balances may not be recoverable.

  INCOME TAXES

     The Company files a consolidated return for federal income tax purposes.
Income taxes for the Company are provided under the liability method considering
the income tax effects of transactions reported in the consolidated financial
statements which are different from the income tax return. The deferred income
tax assets and liabilities represent the future income tax consequences of those
differences, which will either be taxable or deductible when the underlying
assets or liabilities are realized or settled. Prior to May 1997, AWW was a
limited liability company (LLC), as defined by the Internal Revenue Code,
whereby it was not subject to taxation for federal income tax purposes. Under
LLC status, the equity owners reported their shares of AWW's federal taxable
earnings or losses on their personal income tax returns. In May 1997, AWW
converted to a C Corporation for federal income tax purposes and has recorded
current and deferred income tax assets and liabilities existing on the date of
conversion.

  CLOSURE AND REMEDIATION RESERVES

     As of December 31, 1997, the closure and remediation reserves represent
accruals for the total estimated costs associated with the ultimate closure of
the Company's landfarm facilities, including costs of decommissioning, statutory
monitoring costs and incremental direct administrative costs required during the
closure and subsequent postclosure periods. Management periodically reviews the
level of these reserves and will adjust such reserves if estimated costs change
over the remaining estimated life of the landfarm facilities. Landfarm facility
closure bonds and related letters of credit totaling $4 million are posted with
the states of Louisiana and Texas.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  REVENUE RECOGNITION AND CELL PROCESSING RESERVE

     When waste is unloaded at a given site, the Oilfield Waste Division
recognizes the related revenue and records a reserve for the estimated amount of
expenses to be incurred with the treatment of the oilfield waste in order to
match revenues with their related costs. The related treatment costs are charged
against the reserve as such costs are incurred.

     The Liquid Waste Division recognizes revenue from processing services when
material is unloaded at the Company's facilities, if delivered by the customer,
or at the time the service is performed, if the Company collects the materials
from the customer's location. Sales revenue is recognized when the by-product is

  EARNINGS PER SHARE

     Effective December 31, 1997, the Company adopted the provisions of
Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings Per
Share". Under these provisions, earnings per share amounts are based on the
weighted average number of shares of common stock and common stock equivalents
outstanding during the period. The weighted average number of shares used to
compute basic and diluted earnings per share for 1995, 1996, and 1997 is
illustrated below:

     At December 31, 1997, the Company had 10,000 employee stock options which
were not included in the computation of diluted earnings per share because to do
so would have been antidilutive for the period presented.

  INSURANCE

     The Company maintains various types of insurance coverage for its business,
including, without limitation, commercial general liability and commercial auto
liability, workers' compensation and employer liability, pollution legal
liability and a general umbrella policy. The Company has not incurred
significant claims or losses in excess of its insurance limits during the
periods presented in the accompanying consolidated financial statements.

  RISK FACTORS

     An investment in the Company's common stock involves a high degree of risk.
Those risks include, but are not limited to, government regulation, dependence
on the oil and gas industry and foreign customers, absence of a combined
operating history, reliance on key personnel and risks related to the Company's
acquisition strategy.

3.  ACQUISITIONS:

  1996 ACQUISITIONS

     Effective December 14, 1996, U S Liquids Inc. purchased certain assets and
assumed certain liabilities of Campbell Wells by issuing a long-term promissory
note for $27,800,000 and warrants to purchase 1,000,000 shares of U S Liquids
Inc. common stock at an exercise price of $2.00 per share (the "Campbell Wells
Acquisition") to Sanifill. The total purchase price includes a calculation of
the fair value of the warrants at their date of issuance using the Black-Scholes
pricing model with the following assumptions:

Expected stock price volatility......       35.55%
Risk free interest rate..............        6.35%
Expected life of warrants............     10 years

     The Campbell Wells Acquisition was accounted for under the purchase method
of accounting, and the net assets and results of operations since the date of
the Campbell Wells Acquisition are included in the consolidated financial
statements. Costs were allocated to the net assets acquired based on
management's estimate of the fair value of the acquired assets and liabilities
at the date of the Campbell Wells Acquisition. The purchase price has been
allocated as follows (in thousands):

Acquired assets --
     Cash and cash equivalents.......  $   6,001
     Accounts receivable.............      3,980
     Prepaid expenses and other
     current assets..................         61
     Property, plant and equipment...     30,693
     Deferred income tax asset.......      1,628
     Other assets....................        271
Assumed liabilities --
     Accounts payable and accrued
     liabilities.....................     (1,966)
     Closure, remediation and cell
     processing reserves.............    (10,245)
     Deferred income tax liability...     (1,628)
                                       ---------
          Total purchase price.......  $  28,795
                                       =========

     The following table sets forth unaudited pro forma income statement data to
present the effect of the Campbell Wells Acquisition on the Company's results of
operations for the years ended December 31, 1995 and 1996. The income statement
data for Campbell Wells may not necessarily be indicative of the results of
operations that would have been realized had Campbell Wells been operated as a
stand-alone entity.

     As a wholly owned subsidiary of Sanifill, Campbell Wells maintained a
noninterest bearing intercompany account with Sanifill for recording
intercompany charges for costs and expenses, intercompany purchases of equipment
and additions under capital leases and intercompany transfers of cash, among
other transactions. It is not feasible to ascertain the amount of related
interest expense which would have been recorded in the statements of income had
Campbell Wells been operated as a stand-alone entity. The following unaudited
pro forma income statement data includes the revenues and net income of the
Company, plus the acquired operations of Campbell Wells, as if the Campbell
Wells Acquisition was effective on the first day of the year being reported:

Revenue.................................  $  26,246  $  31,138
Net income, excluding intercompany
interest expense........................      1,251      2,370

     Pro forma adjustments for all periods included in the preceding table
primarily relate to (a) the recording of interest expense on the debt incurred
to effect the Campbell Wells Acquisition, (b) the adjustment to depreciation
expense to reflect the revaluation of property, plant and equipment in
conjunction with the Campbell Wells Acquisition purchase price allocation, (c)
the adjustment of insurance expense to reflect the differences in insurance
expenses recorded by U S Liquids compared to the intercompany insurance expenses
allocated to Campbell Wells from Sanifill, and (d) the related income tax
effects of these adjustments. Pro forma balances do not include the effects of
the Company's initial public offering.

     The pro forma combined results presented above are not necessarily
indicative of actual results which might have occurred had the operations and
management teams of the Company and the acquired operations of Campbell Wells
been combined at the beginning of the periods presented.

     In March 1996, Mesa acquired all of the assets of the trap and septic
division of a grease processing company through the purchase of assets. In
September 1996, Mesa acquired all of the assets and assumed all liabilities of a
feed and tallow processing company through the purchase of stock. Mesa paid
$16,000 in cash, net of cash acquired, and issued $925,000 of debt obligations
in conjunction with both of these acquisitions. Both acquisitions were accounted
for under the purchase method of accounting, and the net assets and results of
operations of these acquisitions since their respective dates of acquisition are
included in the consolidated financial statements.

  1997 ACQUISITIONS

     During the fourth quarter of 1997, the Company completed four acquisitions
that were accounted for under the purchase method of accounting. Results of
operations of companies that were acquired and subject to purchase accounting
are included in the consolidated financial statements from the dates of such
acquisitions. The total costs of acquisitions accounted for under the purchase
method were $6,819,000. The consolidated balance sheet as of December 31, 1997,
includes allocations of the respective purchase prices and is subject to final
adjustment. The excess of the aggregate purchase price over the fair value of
the net assets acquired was approximately $5,726,000.

     In addition, the Company has agreed in connection with certain transactions
to pay additional amounts to the sellers upon the achievement by the acquired
businesses of certain negotiated goals, such as targeted earnings levels.
Although the amount and timing of any payments of additional contingent
consideration depend on whether and when these goals are met, the maximum
aggregate amount of contingent consideration potentially payable if all payment
goals are met is $27,880,000 with the achieved goals providing approximately
$31,125,000 of pre-tax income. The contingent consideration is payable in cash
or, in some instances, cash and stock, at the Company's option.

     On October 1, 1997, the Company completed a merger accounted for as a
pooling-of-interests, pursuant to which the Company issued 241,410 shares of its
common stock in exchange for all outstanding shares of the acquired company.
Periods prior to consummation of this merger were not restated to include the
accounts and operations of the acquired company as combined results are not
materially different from the results as presented.

     For purposes of the consolidated federal tax return, the Company has net
operating loss carryforwards available to offset taxable income of the Company
in the future. The net operating loss carryforwards will begin to expire in
2011. In connection with certain acquisitions, ownership changes occurred
resulting in various limitations on certain tax attributes. However, the Company
expects full utilization of these tax attributes prior to their expiration.

     Deferred income taxes are recognized for the tax consequences of temporary
differences by applying enacted statutory tax rates to differences between the
financial reporting and the tax bases of existing assets and liabilities. The
tax effects of significant temporary differences representing deferred income
tax assets and liabilities at December 31, 1996 and 1997 are as follows:

     On December 19, 1997, the Company entered into a revolving credit facility
with a bank group in the amount of $50,000,000. (See Note 14). The initial draw
of $15,250,000 was used to pay off the unpaid portion of the note payable to
Sanifill, which was not previously repaid with proceeds from the Company's
initial public offering. This facility is secured by substantially all of the
assets of the Company. Availability under this credit facility is tied to the
Company's cash flows and liquidity. The credit facility is available to fund
working capital requirements and acquisitions. The credit agreement requires the
Company to comply with certain financial covenants and requires the Company to
obtain the lenders' consent before making any acquisitions with a purchase price
exceeding $7 million, and prohibits the payment of cash dividends. The debt may
be accelerated upon a change in control of the Company or the departure of
senior management without a suitable replacement. Interest on the outstanding
balance is due quarterly and the facility matures on December 20, 2000. Advances
bear interest, at the Company's option, at the prime rate or London Interbank
Offered Rate ("LIBOR"), in each case, plus a margin which is calculated
quarterly based upon the Company's ratio of indebtedness to cash flow. The
Company has agreed to pay a commitment fee varying from 1/4 to 1/2 of 1 percent
per annum on the unused portion of the facility. As of December 31, 1997, the
Company had $34,750,000 available under this facility.

10.  STOCK OPTIONS AND WARRANTS:

     On November 20, 1996, U S Liquids established a stock option plan which
provides, as amended, for a maximum authorized number of shares equal to 15% of
all outstanding common stock at the end of each year, not to exceed a total of
3,000,000 shares. Options vest equally in three annual installments, commencing
on the first anniversary of the date upon which the options were granted, and
expire after being outstanding for a period of 10 years. During June 1997, U S
Liquids established a directors' stock option plan which provides for granting
10,000 options to each director upon their initial election and 5,000 options
each year thereafter. The directors' stock options vest on the date of grant and
expire after 10 years. At December 31, 1997, there were 281,250 nonqualified
stock options granted for corporate development purposes which are contingent
upon the successful completion of certain corporate development activities and,
accordingly, no calculation of the fair value of the nonqualified stock options
will be determined or recorded until the realization of such contingencies. The
Company issued stock warrants in connection with its' Campbell Wells
Acquisition, initial public offering, and as compensation for corporate
consulting. Warrants issued in connection with acquisitions or common stock
offerings are capitalized based on the fair market value on the date of grant.
Stock warrants issued as compensation for consulting activities are expensed as
incurred.

     The following table summarizes activity under the Company's stock option
plan and warrants granted:

     During 1997, 529,500 options were granted which had a weighted average fair
value of $5.91 per option and a weighted average exercise price of $8.69 per
option.

11. COMMITMENTS AND CONTINGENCIES:

  NONCOMPETE AND OILFIELD WASTE DISPOSAL AGREEMENTS

     In conjunction with the Campbell Wells Acquisition, the Company assumed
certain rights and obligations pursuant to an earlier sales agreement entered
into during 1996 between Sanifill and Newpark Resources, Inc. ("Newpark"),
whereby Sanifill sold an unrelated portion of Campbell Wells to Newpark (the
"Newpark Transaction"). The Company has assumed Sanifill's position in a
noncompete agreement entered into between Sanifill and Newpark in conjunction
with the Newpark Transaction, in which Sanifill agreed not to compete with
Newpark in the collection of oilfield waste from offshore sources for a period
of five years.

     US Liquids has also assumed a disposal agreement entered into between
Campbell Wells and Newpark in conjunction with the Newpark Transaction, in which
Newpark agreed to deliver, and Campbell Wells agreed to accept at its Louisiana
landfarms, certain quantities of oilfield waste each year for 25 years

  LEGAL PROCEEDINGS

     Prior to the closing of the Campbell Wells Acquisition, three lawsuits were
brought against Campbell Wells based upon the operation of its Bourg, Louisiana
landfarm. In one of the lawsuits filed against Campbell Wells, approximately 300
individuals residing in and around Grand Bois, Louisiana are seeking unspecified
monetary damages allegedly suffered as a result of (i) odors allegedly emitted
by waste received from Exxon Company U.S.A. ("Exxon") at the landfarm in March
1994, and (ii) alleged air, water and soil contamination in connection with
ongoing operations at the landfarm. The Company was named as a defendant in this
action in January 1998. Trial in this matter on the claims of ten plaintiffs is
set to commence in the 17th Judicial District Court for the Parrish of
Lafourche, Louisiana on July 13, 1998. A second lawsuit, brought by one
individual, seeks unspecified monetary damages allegedly suffered as a result of
odors allegedly emitted by waste received from Exxon at the landfarm in March
1994. This lawsuit is also pending in the 17th Judicial District Court for the
Parrish of Lafourche, Louisiana and trial is set to commence on July 13, 1998.
The Company has not yet been named as a defendant in this action. In the third
lawsuit, six individuals filed suit on March 7, 1996 against Campbell Wells in
the Civil District Court for the Parrish of Orleans, Louisiana, seeking
preliminary and permanent injunctive relief against certain treatment operations
conducted at the Bourg, Louisiana landfarm which the plaintiffs contend have
resulted and will result in adverse health effects by way of emissions of
alleged air pollutants. The plaintiffs' request for a preliminary injunction was
heard during the summer of 1996. On December 30, 1996, the court entered an
order granting in part and denying in part the relief requested by the
plaintiffs. Specifically, the court found that there was no evidence that
emissions resulting from the treatment operations complained of equaled or
exceeded any relevant safety standard, health standard or occupational standard
and, therefore, denied the plaintiffs' request for a temporary injunction
prohibiting such treatment operations. The court did, however, preliminarily
enjoin Campbell Wells (and, thus, indirectly the Company) from treating waste
received from Exxon in March 1994 in one particular treatment cell located
within 500 feet of a building in which one of the plaintiffs resides. In
connection therewith, the court ordered that the Commissioner of the Louisiana
Department of Conservation be made a party to the litigation and substituted for
the plaintiffs on the limited issue of whether Campbell Wells has violated the
location criteria for the particular treatment cell involved. The Company was
named as a defendant in this action in January 1998. No trial date has been

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
set for the plaintiffs' request for permanent injunctive relief; however, based
upon the court's rulings from the preliminary injunction trial and initial
discussions with the Louisiana Department of Conservation, the Company believes
that permanent injunctive relief that might be entered in the action will not
have a material adverse effect upon the Company's consolidated financial
position or results of operations.

     Prior to the closing of the Campbell Wells Acquisition, a class action
lawsuit was filed in the Civil District Court for the Parrish of Orleans,
Louisiana against Campbell Wells seeking unspecified monetary damages allegedly
suffered as a result of alleged air, water and soil contamination in connection
with ongoing operations at its Mermentau, Louisiana landfarm. The Company has
not been named as a defendant in this lawsuit; however, there can be no
assurance that the Company will not subsequently be named as a defendant in this
lawsuit.

     In connection with the Campbell Wells Acquisition, Sanifill agreed, with
certain enumerated exceptions, to retain responsibility for all liabilities of
Campbell Wells as of the closing date of the Campbell Wells Acquisition
including, without limitation, the contingent liabilities associated with such
lawsuits. The obligation of Sanifill to indemnify the Company is limited to $10
million.

     In March 1998, the Company was dismissed as a defendant in a lawsuit
originally filed by Waste Facilities, Inc. in 1994 against Campbell Wells and
others in the District Court of Jim Wells County, Texas.

     In February 1997, an action entitled JUDY GARCIA, ET AL V. RE-CLAIM
ENVIRONMENTAL was filed in the 51st Judicial District Court of Harris County,
Texas. This action was brought by the residents of an apartment complex located
adjacent to one of the Company's processing facilities and alleges that the
defendant is guilty of nuisance, trespass, negligence and gross negligence by
reason of its pollution of the air, soil and ground and surface water and the
release of noxious odors. The plaintiffs have requested unspecified monetary
damages. The Company denies liability and intends to vigorously defend the
action.

     The Company is involved in various other legal actions arising in the
ordinary course of business. Management does not believe that the outcome of
such legal actions will have a material adverse effect on the Company's
consolidated financial position or results of operations.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To City Environmental, Inc.:

     We have audited the accompanying balance sheets of City Environmental, Inc.
(CEI or the Company), which represent certain assets acquired and liabilities
assumed by U S Liquids Inc. from USA Waste Services, Inc., as of June 30, 1996
and 1997, and the related statements of income for each of the three years in
the period ended June 30, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     As discussed in Note 1, the accompanying financial statements have been
prepared pursuant to the purchase agreement between USA Waste Services, Inc.,
and U S Liquids Inc. and were prepared for the purpose of complying with Rule
3-05 of Regulation S-X of the Securities and Exchange Commission and are not
intended to be a complete presentation of City Environmental, Inc.'s assets,
liabilities, operating results or cash flows on a stand-alone basis.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of City Environmental, Inc., as
of June 30, 1996 and 1997, and the results of its operations for each of the
three years in the period ended June 30, 1997, pursuant to the purchase
agreement referred to in Note 1 and in conformity with generally accepted
accounting principles.

1.  BUSINESS AND ORGANIZATION:

     City Environmental, Inc. (CEI or the Company), is a division of City
Management Corporation (CMC), which in turn is a subsidiary of USA Waste
Services, Inc. (USA Waste). For periods up to and including December 31, 1997,
CMC was owned and operated as an independent private company. During January
1998, CMC was acquired by USA Waste. During March 1998, USA Waste entered into
negotiations with U S Liquids Inc. (USL) whereby USL would purchase certain
assets and assume certain liabilities of CEI through a transaction to be
accounted for as an asset purchase.

     The Company treats and disposes hazardous and nonhazardous wastes generated
by commercial, industrial, residential and governmental generators. The Company
operates treatment facilities in Detroit, Michigan, which are accessible by
truck and rail. The Company also operates a truck/tanker fleet to transport
waste materials from customers to its treatment facilities and to deliver
treated waste to landfill sites.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  BASIS OF PRESENTATION

     These financial statements have been prepared to present the financial
position and the results of operations of CEI related to the assets acquired and
liabilities assumed by USL in conformity with generally accepted accounting
principles. The unaudited balance sheet as of March 31, 1998, and the related
statement of income for the three months ended March 31, 1998, reflect purchase
price allocations associated with USA Waste's acquisition of CMC, effective as
of January 1, 1998.

     CEI is a division of CMC and, as such, the balance sheets and statements of
income may not necessarily be indicative of the financial position or results of
operations that would have been realized had CEI been operated as a stand-alone
entity. The statements of income include amounts allocated by CMC to CEI for
corporate management fees, including insurance risk management, legal department
services, cash management, information systems support and executive management
salaries. Management believes the allocation is reasonable.

     As a division of CMC, CEI maintains an interest-bearing intercompany
account with CMC for recording intercompany charges for costs and expenses,
intercompany transfers of equipment and intercompany transfers of cash, among
other transactions. CMC charges CEI interest expense at the rate of 9 percent
per annum of the average of the two prior months' intercompany balances when the
average exceeds $6,060,000 and credits interest income to CEI at a rate of 6
percent per annum when the average is less than $6,060,000. (The $6,060,000 was
established in prior years when CEI transferred the value of its common stock
and additional paid-in capital to the intercompany account with CMC as a result
of CMC becoming an S Corporation.) This method is not indicative of, nor is it
feasible to ascertain, the amount of related net interest expense that would
have been recorded in the accompanying statements of income had CEI operated as
a stand-alone entity. CMC does not maintain debt balances specifically related
to the operations of CEI. The net interest expense reflected in the accompanying
statements of income represents intercompany interest charges from CMC and
external interest expenses on long-term notes payable.

     Due to the manner in which CMC intercompany transactions were recorded, it
is not feasible to present a detailed analysis of transactions reflected in the
intercompany balance with CMC. The change in the intercompany balance with CMC
was $991,000 and $7,561,000 for the years ended June 30, 1996 and 1997,
respectively. For the six months ended December 31, 1997, and for the three
months ended March 31, 1998, the change in intercompany balance with CMC was
$8,346,000 and $(1,013,000), respectively.

     It is also not feasible to present complete statements of cash flows due to
the nature and manner of recording of intercompany transactions; however, the

</TABLE>
  INTERIM FINANCIAL INFORMATION

     The interim financial statements for the nine months ended March 31, 1997,
the six months ended December 31, 1997, and the three months ended March 31,
1998, are unaudited, and certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been omitted. In the opinion of management, all
adjustments, consisting only of normal recurring adjustments, necessary to
fairly present the results of operations with respect to the interim financial
statements have been included. The results of operations for the interim period
are not necessarily indicative of the results for the entire fiscal year.

  USE OF ESTIMATES

     The preparation of financial statements requires management to make
estimates and assumptions that affect the reported amounts of assets acquired
and liabilities assumed, the disclosure of contingent assets acquired and
liabilities assumed at the date of the financial statements and the reported
amounts of revenues and expenses during the reporting period. Actual results
could differ from the estimates.

                            CITY ENVIRONMENTAL, INC.
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  CASH

     Cash represents an imprest account maintained by CEI. At month-end, all
excess cash balances, other than the balance in the imprest account, are
credited to CMC.

  CONCENTRATIONS OF CREDIT RISK

     Accounts receivable potentially subject the Company to concentrations of
credit risk. At June 30, 1996 and 1997, one customer accounted for 15 percent
and 12 percent, respectively, of the total accounts receivable balance. For the
year ended June 30, 1995, three customers accounted for 20 percent of total
revenues. For the years ended June 30, 1997 and 1996, four customers accounted
for 22 percent and 21 percent of total revenues, respectively.

  PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment is recorded at cost. Improvements or
betterments which significantly extend the life of an asset are capitalized.
Expenditures for maintenance and repair costs are charged to operations as
incurred. The cost of assets retired or otherwise disposed of and the related
accumulated depreciation are eliminated from the accounts in the year of
disposal. Gains and losses resulting from property disposals are included in
other income or expense. Depreciation is computed using the straight-line
method.

  LONG-LIVED ASSETS

     Long-lived assets consist primarily of disposal sites, equipment and
permits. Management continually evaluates whether events or circumstances have
occurred that indicate the remaining estimated useful lives of intangible assets
and other long-lived assets may warrant revision or that remaining balances may
not be recoverable.

  INSURANCE

     The Company maintains various types of insurance coverage for its business
through CMC, including, without limitation, commercial general liability and
commercial auto liability, workers' compensation and employer liability,
pollution legal liability and a general umbrella policy. Premiums paid to CMC
may not have been indicative of market rates to obtain such coverage had the
Company operated on a stand-alone basis. The Company has not incurred
significant claims or losses in excess of its insurance limits during the
periods presented in the accompanying financial statements.

  CLOSURE AND REMEDIATION RESERVES

     The closure and remediation reserves represent accruals for the estimated
future costs associated with the ultimate closure of the Company's treatment and
disposal facilities, including costs of decommissioning, statutory monitoring
costs and incremental direct administrative costs required during the closure
and subsequent postclosure periods. The Company accrues for the estimated future
costs over the estimated useful life of the treatment facilities. Management
periodically reviews the estimated future costs and adjusts reserves over the
remaining useful life of the treatment facilities.

  REVENUE RECOGNITION

     CEI recognizes treatment and disposal revenue when waste material is
accepted and treated at the treatment and disposal site, and transportation
revenue at the point of collection, if the Company collects waste from the
customer's location.

  INCOME TAXES

     The operations of CEI are included in the consolidated U.S. federal and
state income tax returns of CMC. The stockholder of CMC elected to be taxed
individually on the Company's taxable income, pursuant

                            CITY ENVIRONMENTAL, INC.
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
to S Corporation rules of the Internal Revenue Code for federal taxes. A
provision for state income taxes is reflected in the historical financial
statements as if CEI were a stand-alone entity.

8.  COMMITMENTS AND CONTINGENCIES:

  LEACHATE AND LANDFILL DISPOSAL AGREEMENT

     In July 1995, CEI entered into an agreement with Carleton Farms, Inc., and
City Sand and Landfill (subsidiaries of CMC), whereby CEI agreed to transport
and treat leachate from these landfills and Carleton Farms, Inc., agreed to
accept CEI's treated waste. The pricing arrangements were not necessarily
indicative of market rates had this agreement been entered into between
unrelated parties. Revenues of $686,765 and $919,946 and cost of operations of
$1,324,612 and $1,600,476 are reflected in the accompanying statements of income
related to this agreement for the years ended June 30, 1996 and 1997,
respectively.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  LEASES

     The Company leases certain sales office facilities and certain equipment
under one-year cancelable operating leases. Rent expense was $7,000, $20,000 and
$23,000 for the years ended June 30, 1995, 1996 and 1997, respectively.

  LEGAL

     The Company is involved in various legal actions arising in the ordinary
course of business. Management does not believe that the outcome of such legal
actions will have a material adverse effect on the Company's financial position
or results of operations.

9.  SUBSEQUENT EVENTS (UNAUDITED):

     Effective January 1, 1998, USA Waste Services, Inc., acquired the
outstanding stock of CMC, including the operations of CEI, through a transaction
accounted for as a purchase.

     In April 1998, USA Waste Services, Inc., signed a definitive agreement to
sell CEI to U S Liquids Inc. through an asset purchase agreement.

10.  EVENTS SUBSEQUENT TO DATE OF REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
     (UNAUDITED):

     On May 7, 1997 U S Liquids Inc. entered into an agreement to acquire
certain assets and assume certain liabilities of CEI for cash and assume debt.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders of
Waste Stream Environmental Inc.:

     We have audited the accompanying combined balance sheet of Waste Stream
Environmental Inc. (a New York corporation) and affiliate as of December 31,
1997, and the related combined statements of income, stockholders' equity and
cash flows for the year then ended. These combined financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these combined financial statements based on our audit.

     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.

     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of Waste
Stream Environmental Inc. and Affiliate as of December 31, 1997, and the results
of their operations and their cash flows for the year then ended in conformity
with generally accepted accounting principles.

                 WASTE STREAM ENVIRONMENTAL INC. AND AFFILIATE
                     NOTES TO COMBINED FINANCIAL STATEMENTS

1.  BUSINESS AND ORGANIZATION:

     Waste Stream Environmental Inc. and its affiliate, Earth Blends, Inc.
(collectively, the Company), are primarily engaged in removing, transporting and
disposing of waste sludge and other waste related products. The Company's
customers, principally commercial industries and governmental units, are mainly
located in New York, Connecticut, New Jersey and Massachusetts. The Company
sells waste treatment plant supplies and provides processing services to its
customers.

     The Company, through Earth Blends, Inc., also transports, markets and sells
N-VIRO soil.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  BASIS OF PRESENTATION

     The individual companies that comprise the Company have been presented on a
combined basis due to their related operations, common ownership by three
individual stockholders and common management control. All significant
intercompany balances and transactions among the aforementioned entities have
been eliminated in combination.

  INTERIM FINANCIAL INFORMATION

     The interim financial statements for the three months ended March 31, 1997
and 1998, are unaudited, and certain information and footnote disclosures,
normally included in financial statements prepared in accordance with generally
accepted accounting principles, have been omitted. In the opinion of management,
all adjustments, consisting only of normal recurring adjustments, necessary to
fairly present the results of operations and cash flows with respect to the
combined interim financial statements have been included. The results of
operations for the interim periods ended March 31, 1997 and 1998, are not
necessarily indicative of the results for the entire fiscal year.

  USE OF ESTIMATES

     The preparation of financial statements requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

  CASH AND CASH EQUIVALENTS

     All highly liquid investments with an original maturity of three months or
less are classified as cash equivalents.

  CONCENTRATIONS OF CREDIT RISK

     Accounts receivable potentially subject the Company to concentrations of
credit risk. At December 31, 1997, 11 percent and 10 percent of total accounts
receivable were associated with two customers. In addition, sales to two
customers represented 21 percent and 8 percent, respectively, of total revenues
for the year ended December 31, 1997.

  INVENTORIES

     Inventories are stated at the lower of cost or market and, at December 31,
1997, consisted of raw materials. Cost is determined using the first-in,
first-out (FIFO) method.

  PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment are recorded at cost. Improvements or
betterments which significantly extend the life of an asset are capitalized.
Expenditures for maintenance and repair costs are charged to operations as
incurred. The cost of assets retired or otherwise disposed of and the related
accumulated

10.  SUBSEQUENT EVENTS:

  INVESTMENT IN JOINT VENTURE

facility.

  DEBT REFINANCING

     In January 1998, the Company entered into a revolving credit facility, a
project credit facility and two equipment loans with a domestic bank.

     The purpose of the revolving credit facility is to provide working capital
to the Company. The borrowings are limited to the lesser of $2 million or 80
percent of eligible receivables, as defined. The facility is subject to
customary loan covenants and drawing conditions. Interest is set at the floating
LIBOR rate plus 2.25 percent.

development of a waste processing facility. Interest will be set at the
borrower's option.

7.73 percent per annum through January 2002. These obligations are secured by
substantially all of the Company's assets and the personal guarantees of the
Company's officers and stockholders.

                         NOTES TO FINANCIAL STATEMENTS

1.  BUSINESS AND ORGANIZATION:

     Parallel Products (the Company) is a California limited partnership
organized in 1991. The Company recovers purified by-products, such as ethanol,
through the processing of its waste streams, acts as a broker and commodity
dealer in various nonpotable liquids and is a provider of services for the
processing, disposal and recovery of liquid waste. The Company's waste
processing operations are located in Rancho Cucamonga, California, and
Louisville, Kentucky. Brokerage operations are not concentrated in one specific
location of the country.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  BASIS OF PRESENTATION

     The accounting records of the Company are maintained on the accrual basis
of accounting.

  USE OF ESTIMATES

     The preparation of financial statements requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

  INTERIM FINANCIAL INFORMATION

     The interim financial statements as of March 31, 1998, and for the three
months ended March 31, 1997 and 1998, are unaudited, and certain information and
footnote disclosures, normally included in financial statements prepared in
accordance with generally accepted accounting principles, have been omitted. In
the opinion of management, all adjustments, consisting only of normal recurring
adjustments, necessary to fairly present the financial position, results of
operations and cash flows with respect to the interim financial statements, have
been included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.

  CASH AND CASH EQUIVALENTS

     All highly liquid investments with an original maturity of three months or
less are classified as cash equivalents.

  RESTRICTED MARKETABLE SECURITIES

     Restricted marketable securities consist of treasury bills and a treasury
note. The Company's investments are classified as held-to-maturity and are
scheduled to mature within 12 months. Held-to-maturity securities represent
those securities that the Company has both the positive intent and ability to
hold to maturity and are carried at amortized cost. Realized gains and losses
and declines in value of securities judged to be other than temporary are
included in interest income. Cost of held-to-maturity securities is determined
by specific identification in computing realized gains and losses.

     At December 31, 1997, certain of the Company's restricted marketable
securities are being held for the benefit of the Company by Wells Fargo Bank
(the Bank), in order to provide additional collateral for the Company's debt
obligations to the Bank. A premature withdrawal of these funds could trigger an
event of default on the outstanding obligations of the Bank. At December 31,
1997, treasury bills in the amount of $492,000 and a treasury note in the amount
of $199,000 are held by the Bank as collateral for the outstanding debt.

  CONCENTRATIONS OF CREDIT RISK

     Accounts receivable potentially subject the Company to concentrations of
credit risk. At December 31, 1997, 21 percent and 13 percent of total accounts
receivable were associated with two customers. In

                                      F-53

                               PARALLEL PRODUCTS
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

addition, sales to three customers represented 13 percent, 11 percent and 10
percent of total revenues for the year ended December 31, 1997.

     The Company's customers are concentrated in the beverage industry.
Management performs ongoing credit analyses of the accounts of its customers and
provides allowances as deemed necessary.

  MAJOR SUPPLIERS

     During 1997, two suppliers accounted for 31 percent and 13 percent of total
purchases. Management believes that alternate sources of supply are available on
comparable terms.

  INVENTORIES

     Inventories are stated at the lower of cost or market and, at December 31,
1997, consisted primarily of finished products such as brokered and manufactured
alcohol. Cost is determined using the first-in, first-out (FIFO) method.

  PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment are recorded at cost. Improvements or
betterments which significantly extend the life of an asset are capitalized.
Expenditures for maintenance and repair costs are charged to operations as
incurred. The cost of assets retired or otherwise disposed of and the related
accumulated depreciation are eliminated from the accounts in the year of
disposal. Gains and losses resulting from property disposals are included in
other income or expense. Depreciation is computed using the straight-line
method.

  INCOME TAXES

     The accompanying financial statements do not include provisions for income
taxes that may be due on the reported net income of the Company, since any
related income taxes are obligations of the partners of the Company.

  REVENUE RECOGNITION

     Revenues are recognized when recycled products are shipped. Revenue from
brokered alcohol is recognized when shipped from the Company's locations or when
delivered if product is shipped from a location other than the Company's two
refineries.

     The Company's revenues consisted of the following for the year ended
December 31, 1997 (in thousands):

By-product sales.....................  $  27,180
Processing revenues..................      2,854

                                       =========

3.  RELATED-PARTY NOTES RECEIVABLE:

     At December 31, 1997, there was a note receivable from a limited partner of
the Company in the amount of $46,000. The borrowing bears interest at 8 percent
with scheduled payments of $750 per month to commence in 1998. The current
portion of the note receivable has been included in prepaid expenses and other
current assets at December 31, 1997.

and the Rancho Cucamonga, California, facility, under the terms of the Company's
credit agreement with the Bank, amended on March 11, 1998.

     On October 11, 1996, the Company entered into a revolving credit facility,
extended on March 11, 1998, with the Bank in the amount of $2,000,000 in two
lines of credit and $600,000 in a term commitment note. The Company also has
existing loans with the Bank which were used to purchase equipment and real
estate. The facility is secured by substantially all of the assets of the
Company. The borrowings under the credit facility, which are used to fund
working capital, are limited to a maximum of 90 percent of the market value of
the treasury notes plus 80 percent of eligible accounts receivable. The Company
is required to maintain a noninterest-bearing deposit account (restricted
marketable securities, see Note 2) over which the Company has no control and
from which deposits will be used as a principal reduction on the credit
facility. The credit agreement requires the Company to comply with certain
financial covenants, such as meeting minimum requirements for earnings before
interest, taxes, depreciation and amortization (EBITDA) coverage ratio, and
prohibits the Company from merging into or consolidating with any other entity.
The credit agreement allows distributions to partners to cover its partners'
federal income tax liability, and any other distributions are prohibited.
Interest on the outstanding balance is due monthly, and the facility matures on
April 30, 1998. Advances bear interest at prime plus 3 percent and prime plus 5
percent for each line of credit, respectively, and prime plus 3 percent for the
term note. Subsequent to year-end, interest rates were reduced to prime plus 2
percent for the entire facility. As of December 31, 1997, availability under the
credit facility was $738,000.

     All of the indebtedness of the Company to the Bank, pursuant to the
parties' loan agreement as amended, stipulates that all bank debt with the Bank
shall be guaranteed by the general partner and two limited partners up to a
principal amount of $4,400,000 each. The Bank's prime rate of interest at
December 31, 1997, was 8.5 percent. Management estimates that the fair value of
its debt obligations approximates the historical value at December 31, 1997.

     Principal payments of long-term debt obligations, including related-party
notes payable, in excess of one year as of December 31, 1997, are as follows (in

in the amounts of $100,000 and $310,000, bearing interest at 8.0 percent and
5.31 percent, respectively, per annum. Annual installments, related to the
$100,000 note, of interest only are due beginning December 1, 1995, and continue
until January 1, 2000, at which time all remaining unpaid principal and interest
shall be due and payable. These notes are subordinated to the payment of all
obligations of the Company to the Bank, pursuant to the terms of a subordination
agreement amended on March 11, 1998.

8.  EMPLOYEE BENEFITS:

     The Company has a 401(k) defined contribution plan available to all
employees who have been with the Company for more than one year. Employees may
contribute up to 15 percent of their salary each year, and the Company may elect

participants who are employed at the end of the plan year and have completed

  SALES COMMITMENTS

     Periodically, the Company enters into ethanol sales contracts with several
of its customers. These contracts are generally short-term in nature and are
used by the customer to ensure an adequate supply of ethanol for the
state-mandated oxygenated fuels requirements. Additionally, the Company enters
into short-term contracts for the purchase of ethanol to ensure an adequate
supply for the formal sales contracts. These purchase commitments did not result
in losses. The Company did not have any formal purchase or sales commitments
outstanding for the year ended December 31, 1997.

  LEGAL PROCEEDINGS

     The Company is subject to claims and legal actions that arise in the
ordinary course of business. Management believes that the ultimate liability
with respect to these claims and legal actions, if any, will not have a material
effect on the financial position of the Company.

     The Company has been informed of possible violations of federal
environmental criminal laws resulting from possible improper handling of
asbestos-containing materials from a site now owned by the Company. The Company
does not expect that the ultimate disposition of these proceedings will have a
material adverse effect on the Company's financial condition or its results of
operations.

10.  SUBSEQUENT EVENTS:

     On April 21, 1998, U S Liquids Inc. acquired the Company for cash, assumed
debt and stock. The transaction was accounted for under the purchase method of
accounting. The acquisition agreement provides for contingent payments up to
$4.2 million, if certain financial and operational goals are met.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To U S Liquids Inc.:

     We have audited the accompanying balance sheets of the U S Liquids Inc.
Predecessor, which represents certain assets acquired and liabilities assumed by
U S Liquids Inc. from Campbell Wells, L.P. and Campbell Wells NORM, L.P.
(collectively "Campbell Wells") which were wholly-owned subsidiaries of
Sanifill, Inc., as of December 31, 1995 and December 13, 1996, and the related
statements of income for the years ended December 31, 1994 and 1995 and for the
period ended December 13, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     As discussed in Note 2, the accompanying financial statements have been
prepared pursuant to the purchase agreement effective December 14, 1996, between
Sanifill, Inc. and U S Liquids Inc. and were prepared for the purpose of
complying with Rule 3-05 of Regulation S-X of the Securities and Exchange
Commission and are not intended to be a complete presentation of Campbell Wells'
assets, liabilities, operating results or cash flows on a stand-alone basis.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the balance sheet of the U S Liquids Inc. Predecessor
as of December 31, 1995 and December 13, 1996, and the results of its operations
for the years ended December 31, 1994 and 1995 and for the period ended December
13, 1996, pursuant to the purchase agreement referred to in Note 2 and in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

1.  THE ACQUISITION:

     Effective December 13, 1996, U S Liquids Inc. ("U S Liquids") purchased
certain assets and assumed certain liabilities of Campbell Wells, L.P. and
Campbell Wells NORM L.P. ("Campbell Wells" the "U S Liquids Inc.
Predecessor," or the "Company"), which were wholly-owned subsidiaries of
Sanifill, Inc. ("Sanifill"), by issuing a long-term promissory note for $27.8
million and warrants to purchase 1,000,000 shares of U S Liquids common stock at
an exercise price of $2.00 per share (the "Campbell Wells Acquisition").
Assets not purchased and excluded from the accompanying predecessor financial
statements for all periods presented include transfer stations and other related
assets of Campbell Wells previously sold by Sanifill to Newpark Resources, Inc.
(the "Newpark Transaction").

     The Company treats and disposes oilfield waste generated in the exploration
for and production of oil and natural gas. The Company has treatment facilities
located in Louisiana and Texas that service the Gulf Coast region of the United
States. The Company also treats oilfield naturally occurring radioactive
material at its treatment facility at Lacassine, Louisiana.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  BASIS OF PRESENTATION

     These financial statements have been prepared to present the financial
position and results of operations of Campbell Wells related to the assets
acquired and liabilities assumed by U S Liquids Inc. under the terms of the
Campbell Wells Acquisition described in Note 1 and in conformity with generally
accepted accounting principles.

     The balance sheets and statements of income may not necessarily be
indicative of the financial position or results of operations that would have
been realized had Campbell Wells been operated as a stand-alone entity. The
statements of income include the amounts allocated by Sanifill to Campbell Wells
for selling, general and administrative expenses based on a percentage of
revenues and direct payroll based costs. Management believes this allocation is
reasonable.

     As a wholly-owned subsidiary of Sanifill, Campbell Wells maintained a
noninterest-bearing intercompany account with Sanifill for recording
intercompany charges for costs and expenses, intercompany purchases of equipment
and additions under capital leases, and intercompany transfers of cash, among
other transactions. It is not feasible to ascertain the amount of related
interest expense which would have been recorded in the accompanying statements
of income had Campbell Wells been operated as a stand-alone entity. Sanifill did
not maintain debt balances specifically related to the operations of Campbell
Wells nor did Sanifill allocate any interest charges to Campbell Wells relating
to Sanifill's corporate debt. The interest expense reflected in the accompanying
statements of income represents the interest portion of capital lease payments
which were paid by Sanifill and directly charged to Campbell Wells.

     Due to the manner in which Sanifill intercompany transactions were recorded
and also due to carve out matters relating to intercompany transactions
associated with the portion of Campbell Wells which was sold by Sanifill to
Newpark, it is not feasible to present a detailed analysis of transactions
reflected in the intercompany balance with Sanifill. The change in the
intercompany balance with Sanifill (net of income) was ($409,000), $462,000, and
$3,776,000 for the years ended December 31, 1994, 1995 and for the period ended
December 13, 1996, respectively.

     It is also not feasible to present complete statements of cash flows,
including unaudited interim cash flow data, due to the nature and manner of
recording of intercompany transactions; however, the following information
presents certain cash flow data related to the operations of Campbell Wells:

  USE OF ESTIMATES

     The preparation of financial statements requires management to make
estimates and assumptions that affect the reported amounts of assets acquired
and liabilities assumed, the disclosure of contingent assets acquired and
liabilities assumed at the date of the financial statements and the reported
amounts of revenues and expenses during the reporting period. Actual results
could differ from those estimates.

  CASH AND CASH EQUIVALENTS

     All highly liquid investments with an original maturity of three months or
less are classified as cash equivalents.

  CONCENTRATIONS OF CREDIT RISK

     Accounts receivable potentially subject the Company to concentrations of
credit risk. At December 31, 1995, two customers accounted for 17 percent and 11
percent, respectively, of the total accounts receivable balance. At December 13,
1996, 19 percent and 50 percent of the total accounts receivable are associated
with two customers, respectively.

     In 1994, one customer accounted for 19 percent of total revenues. During
1995, two customers accounted for 33 percent and 22 percent, respectively, of
total revenues. During 1996, two customers accounted for 41 percent and 31
percent, respectively, of total revenues.

     The Company's customers are concentrated in the oil and gas industry in
Louisiana and Texas.

  PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment is recorded at cost. Improvements or
betterments which significantly extend the life of an asset are capitalized.
Expenditures for maintenance and repair costs are charged to operations as
incurred. The cost of assets retired or otherwise disposed of and the related
accumulated

<PAGE>
                          U S LIQUIDS INC. PREDECESSOR
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
depreciation are eliminated from the accounts in the year of disposal. Gains and
losses resulting from property disposals are included in other income or
expense. Depreciation is computed using the straight-line method.

  CLOSURE AND REMEDIATION RESERVES

     The closure and remediation reserves represent accruals for the total
estimated future costs associated with the ultimate closure of the Company's
landfarm facilities, including costs of decommissioning and statutory monitoring
costs required during the closure and subsequent postclosure periods. Management
periodically reviews the level of these reserves and adjusts them to reflect its
current estimate of the total costs necessary to complete the closure and
remediation of its landfarm facilities. In conjunction with U S Liquids'
acquisition of certain assets and assumption of certain liabilities of Campbell
Wells, Sanifill has agreed to maintain landfarm facility closure bonds and
related letters of credit totalling $4 million posted with the states of
Louisiana and Texas through December 31, 1997, at which time U S Liquids will
replace these closure bonds and letters of credit with similar instruments.

  REVENUE RECOGNITION AND CELL PROCESSING RESERVE

     When waste is unloaded at a given site, Campbell Wells recognizes the
related revenue and records a reserve for the estimated amount of expenses to be
incurred with the treatment of the oil field waste in order to match revenues
with their related costs. The related treatment costs are charged against the
reserve as such costs are incurred.

  INCOME TAXES

     The operations of Campbell Wells were included in the consolidated U.S.
federal income tax return of Sanifill, Inc., and no allocations of income taxes
were reflected in the historical statements of operations. For purposes of these
predecessor financial statements, current and deferred income taxes have been
provided on a separate return basis.

  NEW ACCOUNTING STANDARD

     Effective January 1, 1996, the Company adopted the provisions of Statement
of Financial Accounting Standards (SFAS) No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."
Under these provisions, the Company reviews certain long-lived assets for
impairment whenever events indicate that the carrying amount of an asset may not
be recoverable and recognizes an impairment loss under certain circumstances in
the amount by which the carrying value exceeds the fair value of the asset. In
making this assessment, the Company considered the estimated future undiscounted
cash flows of the Company's long-lived assets on the basis of continuing
operations, versus the current market value of such assets on a held for sale
basis. The adoption of SFAS No. 121 had no impact on the Company's financial
position or results of operations.

8.  COMMITMENTS AND CONTINGENCIES:

  NONCOMPETE AGREEMENT

     Under the terms of the Newpark Transaction, Campbell Wells and Sanifill
agreed not to compete with Newpark Resources, Inc., in the collection of
oilfield waste from offshore sources for a period of five years. This agreement
was assumed by U S Liquids pursuant to the Campbell Wells Acquisition.

  OILFIELD WASTE DISPOSAL AGREEMENT

     In connection with the Newpark Transaction, Campbell Wells signed a
disposal agreement dated June 4, 1996, in which Newpark Resources, Inc., agreed
to deliver, and Campbell Wells agreed to accept at its Louisiana landfarms,
certain quantities of oilfield waste each year for 25 years beginning June 1996,
for a specified price, subject to adjustment, and at specified annual minimum
volume levels. This agreement was assumed by U S Liquids pursuant to the
Campbell Wells Acquisition.

  LEASES

     The Company leases office facilities under noncancelable leases. Rent
expense was approximately $214,000, $202,000 and $214,000 for the years ended
December 31, 1994 and 1995, and for the period ended December 13, 1996,
respectively.

  LEGAL PROCEEDINGS

     Prior to the closing of the Campbell Wells Acquisition, three lawsuits were
brought against Campbell Wells based upon the operation of its Bourg, Louisiana
landfarm. In one of the lawsuits filed against Campbell Wells, approximately 300
individuals residing in and around Grand Bois, Louisiana are seeking unspecified
monetary damages allegedly suffered as a result of (i) odors allegedly emitted
by waste received from Exxon Company U.S.A. ("Exxon") at the landfarm in March
1994, and (ii) alleged air, water and soil contamination in connection with
ongoing operations at the landfarm. The Company was named as a defendant in this
action in January 1998. Trial in this matter on the claims of ten plaintiffs is
set to commence in the 17th Judicial District Court for the Parrish of
Lafourche, Louisiana on July 13, 1998. A second lawsuit, brought by one
individual, seeks unspecified monetary damages allegedly suffered as a result of
odors allegedly emitted by waste received from Exxon at the landfarm in March
1994. This lawsuit is also pending in the 17th Judicial District Court for the
Parrish of Lafourche, Louisiana and trial is set to commence on July 13, 1998.
The Company has not yet been named as a defendant in this action. In the third
lawsuit, six individuals filed suit on March 7, 1996 against Campbell Wells in
the Civil District Court for the Parrish of Orleans, Louisiana, seeking
preliminary and permanent injunctive relief against certain treatment operations
conducted at the Bourg, Louisiana landfarm which the plaintiffs contend have
resulted and will result in adverse health effects by way of emissions of
alleged air pollutants. The plaintiffs' request for a preliminary injunction was
heard during the summer of 1996. On December 30, 1996, the court entered an
order granting in part and denying in part the relief requested by the
plaintiffs. Specifically, the court found that there was no evidence that
emissions resulting from the treatment operations complained of equaled or
exceeded any relevant safety standard, health standard or occupational standard
and, therefore, denied the plaintiffs' request for a temporary injunction
prohibiting such treatment operations. The court did, however, preliminarily
enjoin Campbell Wells (and, thus, indirectly the Company) from treating waste
received from Exxon in March 1994 in one particular treatment cell located
within 500 feet of a building in which one of the plaintiffs resides. In
connection therewith, the court ordered that the Commissioner of the Louisiana
Department of Conservation be made a party to the litigation and substituted for
the plaintiffs on the limited issue of whether Campbell Wells has violated the
location criteria for the particular treatment cell involved. The Company was
named as a defendant in this action in January 1998. No trial date has been set
for the plaintiffs' request for permanent injunctive relief; however, based upon
the court's rulings from the preliminary injunction trial and initial
discussions with the Louisiana Department of Conservation, the

Company believes that permanent injunctive relief that might be entered in the
action will not have a material adverse effect upon the Company's consolidated
financial position or results of operations.

     Prior to the closing of the Campbell Wells Acquisition, a class action
lawsuit was filed in the Civil District Court for the Parrish of Orleans,
Louisiana against Campbell Wells seeking unspecified monetary damages allegedly
suffered as a result of alleged air, water and soil contamination in connection
with ongoing operations at the Mermentau, Louisiana landfarm. The Company has
not been named as a defendant in this lawsuit; however, there can be no
assurance that the Company will not subsequently be named as a defendant in this
lawsuit.

     In the Campbell Wells Acquisition Agreement, Sanifill agreed, with certain
enumerated exceptions, to retain responsibility for all liabilities of Campbell
Wells as of the closing date of the Campbell Wells Acquisition including,
without limitation, the contingent liabilities associated with such lawsuits.
The obligation of Sanifill to indemnify the Company is limited to $10 million.

     In March 1998, the Company was dismissed as a defendant in a lawsuit
originally filed by Waste Facilities, Inc. in 1994 against Campbell Wells and
others in the District Court of Jim Wells County, Texas.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Company's Certificate of Incorporation contains a provision which
limits, to the fullest extent permitted by Delaware law, the liability of a
director to the Company or its stockholders from monetary damages for a breach
of such director's fiduciary duty as a director. Delaware law presently permits
such limitation of a director's liability except where a director (i) breaches
his or her duty of loyalty to the Company or its stockholders, (ii) fails to act
in good faith or engages in intentional misconduct or a knowing violation of
law, (iii) authorizes payment of an unlawful dividend or stock repurchase, or
(iv) obtains an improper personal benefit.

     The Company's Certificate of Incorporation also provides that directors and
officers shall be indemnified against liabilities arising from their service as
directors or officers to the fullest extent permitted by law, which generally
requires that the individual act in good faith and in a manner he or she
reasonably believes to be in or not opposed to the Company's best interests. The
Company has obtained directors and officers liability insurance to limit its
exposure under these provisions.

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

     (b)  The undersigned registrant hereby undertakes that:

          (1)  for purposes of determining any liability under the Securities
               Act of 1993, the information omitted from the form of prospectus
               filed as part of this registration statement in reliance upon
               Rule 430A and contained in a form of prospectus filed by the
               registrant pursuant to Rule 424(b)(1) or 497(b) under the
               Securities Act shall be deemed to be a part of this registration
               statement as of the time it was declared effective.

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

      restrictions that are burdensome to the Company or any of its
      subsidiaries; except where such failure to be valid and in full force and
      effect or to be in compliance, the occurrence of any such event or the
      presence of any such restriction would not, singly or in the aggregate,
      have a material adverse effect on the business, prospects, financial
      condition or results of operations of the Company and its subsidiaries,
      taken as a whole. 

            (n) There are no costs or liabilities associated with Environmental
      Laws (including, without limitation, any capital or operating expenditures
      required for clean-up, closure of properties or compliance with
      Environmental Laws or any Authorization, any related constraints on
      operating activities and any potential liabilities to third parties) which
      would, singly or in the aggregate, have a material adverse effect on the
      business, prospects, financial condition or results of operations of the
      Company and its subsidiaries, taken as a whole. 

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

            (p) Arthur Andersen LLP are independent public accountants with
      respect to the Company and its subsidiaries as required by the Act. 

            (q) The consolidated financial statements included in the
      Registration Statement and the Prospectus (and any amendment or supplement
      thereto), together with related schedules and notes, present fairly the
      consolidated financial position, results of operations and changes in
      financial position of the Company and its subsidiaries on the basis stated
      therein at the respective dates or for the respective periods to which
      they apply; such statements and related schedules and notes have been
      prepared in accordance with generally accepted accounting principles
      consistently applied throughout the periods involved, except as disclosed
      therein; the supporting schedules, if any, included in the Registration
      Statement present fairly in accordance with generally accepted accounting
      principles the information required to be stated therein; and the other
      financial and statistical information and data set forth in the
      Registration Statement and the Prospectus (and any amendment or supplement
      thereto) are, in all material respects, accurately presented and prepared
      on a basis consistent with such financial statements and the books and
      records of the Company. 

            (r) The Company is not and, after giving effect to the offering and
      sale of the Shares and the application of the proceeds thereof as
      described in the Prospectus, will not 

                                      -10-
<PAGE>
      be, an "investment company" as such term is defined in the Investment
      Company Act of 1940, as amended. 

            (s) There are no contracts, agreements or understandings between the
      Company and any person granting such person the right to require the
      Company to file a registration statement under the Act with respect to any
      securities of the Company or to require the Company to include such
      securities with the Shares registered pursuant to the Registration
      Statement.

            (t) Since the respective dates as of which information is given in
      the Prospectus other than as set forth in the Prospectus (exclusive of any
      amendments or supplements thereto subsequent to the date of this
      Agreement), (i) there has not occurred any material adverse change or any
      development involving a prospective material adverse change in the
      condition, financial or otherwise, or the earnings, business, management
      or operations of the Company and its subsidiaries, taken as a whole, (ii)
      there has not been any material adverse change or any development
      involving a prospective material adverse change in the capital stock or in
      the long-term debt of the Company or any of its subsidiaries and (iii)
      neither the Company nor any of its subsidiaries has incurred any material
      liability or obligation, direct or contingent. 

            (u) Each certificate signed by any officer of the Company and
      delivered to the Underwriters or counsel for the Underwriters shall be
      deemed to be a representation and warranty by the Company to the
      Underwriters as to the matters covered thereby.

      SECTION 7. INDEMNIFICATION.

            (a) The Company agrees to indemnify and hold harmless each
      Underwriter, its directors, its officers and each person, if any, who
      controls any Underwriter within the meaning of Section 15 of the Act or
      Section 20 of the Securities Exchange Act of 1934, as amended (the
      "EXCHANGE ACT"), from and against any and all losses, claims, damages,
      liabilities and judgments (including, without limitation, any legal or
      other expenses incurred in connection with investigating or defending any
      matter, including any action, that could give rise to any such losses,
      claims, damages, liabilities or judgments) caused by any untrue statement
      or alleged untrue statement of a material fact contained in the
      Registration Statement (or any amendment thereto), the Prospectus (or any
      amendment or supplement thereto) or any preliminary prospectus, or caused
      by any omission or alleged omission to state therein a material fact
      required to be stated therein or necessary to make the statements therein
      not misleading, except insofar as such losses, claims, damages,
      liabilities or judgments are caused by any such untrue statement or
      omission or alleged untrue statement or omission based upon information
      relating to any Underwriter furnished in writing to the Company by such
      Underwriter through you expressly for use therein; PROVIDED, HOWEVER, that
      the foregoing indemnity agreement with respect to any preliminary
      prospectus shall not inure to the benefit of any Underwriter who failed to
      deliver a Prospectus (as then amended or supplemented, provided by the
      Company to the several Underwriters in the requisite

                                      -11-
<PAGE>
      quantity and on a timely basis to permit proper delivery on or prior to
      the Closing Date) to the person asserting any losses, claims, damages and
      liabilities and judgments caused by any untrue statement or alleged untrue
      statement of a material fact contained in any preliminary prospectus, or
      caused by any omission or alleged omission to state therein a material
      fact required to be stated therein or necessary to make the statements
      therein not misleading, if such material misstatement or omission or
      alleged material misstatement or omission was cured in such Prospectus and
      such Prospectus was required by law to be delivered at or prior to the
      written confirmation of sale to such person.

            (b) Each Underwriter agrees, severally and not jointly, to indemnify
      and hold harmless the Company, its directors, its officers who sign the
      Registration Statement and each person, if any, who controls the Company
      within the meaning of Section 15 of the Act or Section 20 of the Exchange
      Act, to the same extent as the foregoing indemnity from the Company to
      such Underwriter but only with reference to information relating to such
      Underwriter furnished in writing to the Company by such Underwriter
      through you expressly for use in the Registration Statement (or any
      amendment thereto), the Prospectus (or any amendment or supplement
      thereto) or any preliminary prospectus.

            (c) In case any action shall be commenced involving any person in
      respect of which indemnity may be sought pursuant to Section 7(a) or 7(b)
      (the "indemnified party"), the indemnified party shall promptly notify the
      person against whom such indemnity may be sought (the "indemnifying
      party") in writing and the indemnifying party shall assume the defense of
      such action, including the employment of counsel reasonably satisfactory
      to the indemnified party and the payment of all fees and expenses of such
      counsel, as incurred (except that in the case of any action in respect of
      which indemnity may be sought pursuant to both Sections 7(a) and 7(b), the
      Underwriter shall not be required to assume the defense of such action
      pursuant to this Section 7(c), but may employ separate counsel and
      participate in the defense thereof, but the fees and expenses of such
      counsel, except as provided below, shall be at the expense of such
      Underwriter). Any indemnified party shall have the right to employ
      separate counsel in any such action and participate in the defense
      thereof, but the fees and expenses of such counsel shall be at the expense
      of the indemnified party unless (i) the employment of such counsel shall
      have been specifically authorized in writing by the indemnifying party,
      (ii) the indemnifying party shall have failed to assume the defense of
      such action or employ counsel reasonably satisfactory to the indemnified
      party or (iii) the named parties to any such action (including any
      impleaded parties) include both the indemnified party and the indemnifying
      party, and the indemnified party shall have been advised by such counsel
      that there may be one or more legal defenses available to it which are
      different from or additional to those available to the indemnifying party
      (in which case the indemnifying party shall not have the right to assume
      the defense of such action on behalf of the indemnified party). In any
      such case, the indemnifying party shall not, in connection with any one
      action or separate but substantially similar or related actions in the
      same jurisdiction arising out of the same general allegations or
      circumstances, be liable for the fees and expenses of more than one
      separate firm of attorneys (in addition to any local counsel) for all
      indemnified parties and all such fees and expenses shall be reimbursed as

                                      -12-
<PAGE>
      they are incurred. Such firm shall be designated in writing by Donaldson,
      Lufkin & Jenrette Securities Corporation, in the case of parties
      indemnified pursuant to Section 7(a), and by the Company, in the case of
      parties indemnified pursuant to Section 7(b). The indemnifying party shall
      indemnify and hold harmless the indemnified party from and against any and
      all losses, claims, damages, liabilities and judgments by reason of any
      settlement of any action (i) effected with its written consent or (ii)
      effected without its written consent if the settlement is entered into
      more than twenty business days after the indemnifying party shall have
      received a request from the indemnified party for reimbursement for the
      fees and expenses of counsel (in any case where such fees and expenses are
      at the expense of the indemnifying party) and, prior to the date of such
      settlement, the indemnifying party shall have failed to comply with such
      reimbursement request. No indemnifying party shall, without the prior
      written consent of the indemnified party, effect any settlement or
      compromise of, or consent to the entry of judgment with respect to, any
      pending or threatened action in respect of which the indemnified party is
      or could have been a party and indemnity or contribution may be or could
      have been sought hereunder by the indemnified party, unless such
      settlement, compromise or judgment (i) includes an unconditional release
      of the indemnified party from all liability on claims that are or could
      have been the subject matter of such action and (ii) does not include a
      statement as to or an admission of fault, culpability or a failure to act,
      by or on behalf of the indemnified party.

            (d) To the extent the indemnification provided for in this Section 7
      is unavailable to an indemnified party or insufficient in respect of any
      losses, claims, damages, liabilities or judgments referred to therein,
      then each indemnifying party, in lieu of indemnifying such indemnified
      party, shall contribute to the amount paid or payable by such indemnified
      party as a result of such losses, claims, damages, liabilities and
      judgments (i) in such proportion as is appropriate to reflect the relative
      benefits received by the Company on the one hand and the Underwriters on
      the other hand from the offering of the Shares or (ii) if the allocation
      provided by clause 7(d)(i) above is not permitted by applicable law, in
      such proportion as is appropriate to reflect not only the relative
      benefits referred to in clause 7(d)(i) above but also the relative fault
      of the Company on the one hand and the Underwriters on the other hand in
      connection with the statements or omissions which resulted in such losses,
      claims, damages, liabilities or judgments, as well as any other relevant
      equitable considerations. The relative benefits received by the Company on
      the one hand and the Underwriters on the other hand shall be deemed to be
      in the same proportion as the total net proceeds from the offering (after
      deducting underwriting discounts and commissions, but before deducting
      expenses) received by the Company, and the total underwriting discounts
      and commissions received by the Underwriters, bear to the total price to
      the public of the Shares, in each case as set forth in the table on the
      cover page of the Prospectus. The relative fault of the Company on the one
      hand and the Underwriters on the other hand shall be determined by
      reference to, among other things, whether the untrue or alleged untrue
      statement of a material fact or the omission or alleged omission to state
      a material fact relates to information supplied by the Company or the
      Underwriters and the parties relative intent, knowledge, access to
      information and opportunity to correct or prevent such statement or
      omission.

                                      -13-
<PAGE>
            The Company and the Underwriters agree that it would not be just and
      equitable if contribution pursuant to this Section 7(d) were determined by
      pro rata allocation (even if the Underwriters were treated as one entity
      for such purpose) or by any other method of allocation which does not take
      account of the equitable considerations referred to in the immediately
      preceding paragraph. The amount paid or payable by an indemnified party as
      a result of the losses, claims, damages, liabilities or judgments referred
      to in the immediately preceding paragraph shall be deemed to include,
      subject to the limitations set forth above, any legal or other expenses
      incurred by such indemnified party in connection with investigating or
      defending any matter, including any action, that could have given rise to
      such losses, claims, damages, liabilities or judgments. Notwithstanding
      the provisions of this Section 7, no Underwriter shall be required to
      contribute any amount in excess of the amount by which the total price at
      which the Shares underwritten by it and distributed to the public were
      offered to the public exceeds the amount of any damages which such
      Underwriter has otherwise been required to pay by reason of such untrue or
      alleged untrue statement or omission or alleged omission. No person guilty
      of fraudulent misrepresentation (within the meaning of Section 11(f) of
      the Act) shall be entitled to contribution from any person who was not
      guilty of such fraudulent misrepresentation. The Underwriters' obligations
      to contribute pursuant to this Section 7(d) are several in proportion to
      the respective number of Shares purchased by each of the Underwriters
      hereunder and not joint.

            (e) The remedies provided for in this Section 7 are not exclusive
      and shall not limit any rights or remedies which may otherwise be
      available to any indemnified party at law or in equity.

      SECTION 8. CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The several
obligations of the Underwriters to purchase the Firm Shares under this Agreement
are subject to the satisfaction of each of the following conditions:

            (a) All the representations and warranties of the Company contained
      in this Agreement shall be true and correct on the Closing Date with the
      same force and effect as if made on and as of the Closing Date.

            (b) If the Company is required to file a Rule 462(b) Registration
      Statement after the effectiveness of this Agreement, such Rule 462(b)
      Registration Statement shall have become effective by 10:00 P.M., New York
      City time, on the date of this Agreement; and no stop order suspending the
      effectiveness of the Registration Statement shall have been issued and no
      proceedings for that purpose shall have been commenced or shall be pending
      before or contemplated by the Commission. 

            (c) You shall have received on the Closing Date a certificate dated
      the Closing Date, signed by Michael P. Lawlor and W. Gregory Orr, in their
      capacities as the Chief Executive Officer and President of the Company,
      confirming the matters set forth in Sections 6(t), 8(a) and 8(b) and that
      the Company has complied with all of the agreements 

                                      -14-
<PAGE>
      and satisfied all of the conditions herein contained and required to be
      complied with or satisfied by the Company on or prior to the Closing Date.


            (d) Since the respective dates as of which information is given in
      the Prospectus other than as set forth in the Prospectus (exclusive of any
      amendments or supplements thereto subsequent to the date of this
      Agreement), (i) there shall not have occurred any change or any
      development involving a prospective change in the condition, financial or
      otherwise, or the earnings, business, management or operations of the
      Company and its subsidiaries, taken as a whole, (ii) there shall not have
      been any change or any development involving a prospective change in the
      capital stock or in the long-term debt of the Company or any of its
      subsidiaries and (iii) neither the Company nor any of its subsidiaries
      shall have incurred any liability or obligation, direct or contingent, the
      effect of which, in any such case described in clause 8(d)(i), 8(d)(ii) or
      8(d)(iii), in your judgment, is material and adverse and, in your
      judgment, makes it impracticable to market the Shares on the terms and in
      the manner contemplated in the Prospectus. 

            (e) You shall have received on the Closing Date an opinion
      (satisfactory to you and counsel for the Underwriters), dated the Closing
      Date, of Hartzog Conger & Cason, counsel for the Company, to the effect
      that:

            qualified and is in good standing as a foreign corporation
            authorized to do business in each jurisdiction in which the nature
            of its business or its ownership or leasing of property requires
            such qualification, except where the failure to be so qualified
            would not have a material adverse effect on the business, prospects,
            financial condition or results of operations of the Company and its
            subsidiaries, taken as a whole; 

                  (iii) all the outstanding shares of capital stock of the
            Company have been duly authorized and validly issued and are fully
            paid, non-assessable and not subject to any preemptive or similar
            rights; 

                  (iv) the Shares have been duly authorized and, when issued and
            delivered to the Underwriters against payment therefor as provided
            by this Agreement, will be validly issued, fully paid and
            non-assessable, and the issuance of such Shares will not be subject
            to any preemptive or similar rights;

            free and clear of any security interest, claim, lien, encumbrance or
            adverse interest of any nature; 

                  (vi) this Agreement has been duly authorized, executed and
            delivered by the Company; 

                  (vii) the authorized capital stock of the Company conforms as

            the Act, no stop order suspending its effectiveness has been issued
            and no proceedings for that purpose are, to the best of such
            counsel's knowledge after due inquiry, pending before or
            contemplated by the Commission; 

                  (ix) the statements under the captions "____________________",

            any of its subsidiaries is in default in the performance of any
            obligation, agreement, covenant or condition contained in any
            indenture, loan agreement, mortgage, lease or other agreement or

            taken as a whole, to which the Company or any of its subsidiaries is
            a party or by which the Company or any of its subsidiaries or their
            respective property is bound;

            subsidiaries, taken as a whole, to which the Company or any of its
            subsidiaries is a party or by which the Company or any of its
            subsidiaries or their respective property is bound, (C) violate or

                  (xiii) neither the Company nor any of its subsidiaries has
            violated any Environmental Law, any provisions of the Employee
            Retirement Income Security Act of 1974, as amended, or any
            provisions of the Foreign Corrupt Practices Act, or the rules and
            regulations promulgated thereunder, except for such violations
            which, singly or in the aggregate, would not have a material adverse
            effect on the business, prospects, financial condition or results of
            operation of the Company and its subsidiaries, taken as a whole;

                  (xiv) each of the Company and its subsidiaries has such
            Authorizations of, and has made all filings with and notices to, all
            governmental or regulatory authorities and self-regulatory
            organizations and all courts and other tribunals, including, without
            limitation, under any applicable Environmental Laws, as are
            necessary to own, lease, license and operate its respective
            properties and to conduct its business, except where the failure to
            have any such Authorization or to make any such filing or notice
            would not, singly or in the aggregate, have a material adverse
            effect on the business, prospects, financial condition or results of
            operations of the Company and its subsidiaries, taken as a whole;
            each such Authorization is valid and in full force and effect and
            each of the Company and its subsidiaries is in compliance with all
            the terms and conditions thereof and with the rules and regulations
            of the authorities and governing bodies having jurisdiction with
            respect thereto; and no event has occurred (including, without
            limitation, the receipt of any notice from any authority or
            governing body) which allows or, after notice or lapse of time or
            both, would allow, revocation, suspension or termination of any such
            Authorization or results or, after notice or lapse of time or both,
            would result in any other impairment of the rights of the holder of
            any such Authorization; and such Authorizations contain no
            restrictions that are burdensome to the Company or any of 

                                      -17-
<PAGE>
            its subsidiaries; except where such failure to be valid and in full
            force and effect or to be in compliance, the occurrence of any such
            event or the presence of any such restriction would not, singly or
            in the aggregate, have a material adverse effect on the business,
            prospects, financial condition or results of operations of the
            Company and its subsidiaries, taken as a whole; 

                  (xv) the Company is not and, after giving effect to the
            offering and sale of the Shares and the application of the proceeds
            thereof as described in the Prospectus, will not be, an "investment
            company" as such term is defined in the Investment Company Act of
            1940, as amended; 

                  (xvi) to the best of such counsel's knowledge after due
            inquiry, there are no contracts, agreements or understandings
            between the Company and any person granting such person the right to
            require the Company to file a registration statement under the Act
            with respect to any securities of the Company or to require the
            Company to include such securities with the Shares registered
            pursuant to the Registration Statement; and 

                  (xvii) (A) the Registration Statement and the Prospectus and
            any supplement or amendment thereto (except for the financial
            statements and other financial data included therein as to which no
            opinion need be expressed) comply as to form with the Act, (B) such
            counsel has no reason to believe that at the time the Registration
            Statement became effective or on the date of this Agreement, the
            Registration Statement and the prospectus included therein (except
            for the financial statements and other financial data as to which
            such counsel need not express any belief) contained any untrue
            statement of a material fact or omitted to state a material fact
            required to be stated therein or necessary to make the statements
            therein not misleading and (C) such counsel has no reason to believe
            that the Prospectus, as amended or supplemented, if applicable
            (except for the financial statements and other financial data, as
            aforesaid) contains any untrue statement of a material fact or omits
            to state a material fact necessary in order to make the statements
            therein, in the light of the circumstances under which they were
            made, not misleading. 

      The opinion of Hartzog Conger & Cason described in Section 8(e) above
shall be rendered to you at the request of the Company and shall so state
therein.


            (f) You shall have received on the Closing Date an opinion, dated
      the Closing Date, of McDermott, Will & Emery, counsel for the
      Underwriters, as to the matters referred to in Sections 8(e)(iv),
      8(e)(vi), 8(e)(ix) (but only with respect to the statements under the
      caption "Description of Capital Stock" and "Underwriting") and 8(e)(xvii).

            In giving such opinions with respect to the matters covered by
      Section 8(e)(xvii), Hartzog Conger & Cason and McDermott, Will & Emery may
      state that their opinion and 

                                      -18-
<PAGE>
      belief are based upon their participation in the preparation of the
      Registration Statement and Prospectus and any amendments or supplements
      thereto and review and discussion of the contents thereof, but are without
      independent check or verification except as specified.

            (g) You shall have received, on each of the date hereof and the
      Closing Date, a letter dated the date hereof or the Closing Date, as the
      case may be, in form and substance satisfactory to you, from Arthur
      Andersen LLP, independent public accountants, containing information and
      statements of the type ordinarily included in accountants' "comfort
      letters" to Underwriters with respect to the financial statements and
      certain financial information contained in the Registration Statement and
      the Prospectus.

            (h) The Company shall have delivered to you the agreements specified
      in Section 2 hereof which agreements shall be in full force and effect on
      the Closing Date. 

            (i) The Shares shall have been duly listed, subject to notice of
      issuance, on the AMEX.

            (j) The Company shall not have failed on or prior to the Closing
      Date to perform or comply with any of the agreements herein contained and
      required to be performed or complied with by the Company on or prior to
      the Closing Date.

            The several obligations of the Underwriters to purchase any
      Additional Shares hereunder are subject to the delivery to you on the
      applicable Option Closing Date of such documents as you may reasonably
      request with respect to the good standing of the Company, the due
      authorization and issuance of such Additional Shares and other matters
      related to the issuance of such Additional Shares.

      SECTION 9. EFFECTIVENESS OF AGREEMENT AND TERMINATION. This Agreement
shall become effective upon the execution and delivery of this Agreement by the
parties hereto.

            This Agreement may be terminated at any time on or prior to the
      Closing Date by you by written notice to the Company if any of the
      following has occurred: (i) any outbreak or escalation of hostilities or
      other national or international calamity or crisis or change in economic
      conditions or in the financial markets of the United States or elsewhere
      that, in your judgment, is material and adverse and, in your judgment,
      makes it impracticable to market the Shares on the terms and in the manner
      contemplated in the Prospectus, (ii) the suspension or material limitation
      of trading in securities or other instruments on the New York Stock
      Exchange, the American Stock Exchange, the Chicago Board of Options
      Exchange, the Chicago Mercantile Exchange, the Chicago Board of Trade or
      the Nasdaq National Market or limitation on prices for securities or other
      instruments on any such exchange or the Nasdaq National Market, (iii) the
      suspension of trading of any securities of the Company on any exchange or
      in the over-the-counter market, (iv) the enactment, publication, decree or
      other promulgation of any federal or state statute, regulation, rule or
      order of any court or other governmental authority which in your opinion
      materially and 

                                      -19-
<PAGE>
      adversely affects, or will materially and adversely affect, the business,
      prospects, financial condition or results of operations of the Company and
      its subsidiaries, taken as a whole, (v) the declaration of a banking
      moratorium by either federal or New York State authorities or (vi) the
      taking of any action by any federal, state or local government or agency
      in respect of its monetary or fiscal affairs which in your opinion has a
      material adverse effect on the financial markets in the United States.

      If on the Closing Date or on an Option Closing Date, as the case may be,
any one or more of the Underwriters shall fail or refuse to purchase the Firm
Shares or Additional Shares, as the case may be, which it has or they have
agreed to purchase hereunder on such date and the aggregate number of Firm
Shares or Additional Shares, as the case may be, which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase is not more
than one-tenth of the total number of Firm Shares or Additional Shares, as the
case may be, to be purchased on such date by all Underwriters, each
non-defaulting Underwriter shall be obligated severally, in the proportion which
the number of Firm Shares set forth opposite its name in Schedule I bears to the
total number of Firm Shares which all the non-defaulting Underwriters have
agreed to purchase, or in such other proportion as you may specify, to purchase
the Firm Shares or Additional Shares, as the case may be, which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase on such
date; PROVIDED that in no event shall the number of Firm Shares or Additional
Shares, as the case may be, which any Underwriter has agreed to purchase
pursuant to Section 2 hereof be increased pursuant to this Section 9 by an
amount in excess of one-ninth of such number of Firm Shares or Additional
Shares, as the case may be, without the written consent of such Underwriter. If
on the Closing Date any Underwriter or Underwriters shall fail or refuse to
purchase Firm Shares and the aggregate number of Firm Shares with respect to
which such default occurs is more than one-tenth of the aggregate number of Firm
Shares to be purchased by all Underwriters and arrangements satisfactory to you
and the Company for purchase of such Firm Shares are not made within 48 hours
after such default, this Agreement will terminate without liability on the part
of any non-defaulting Underwriter and the Company. In any such case which does
not result in termination of this Agreement, either you or the Company shall
have the right to postpone the Closing Date, but in no event for longer than
seven days, in order that the required changes, if any, in the Registration
Statement and the Prospectus or any other documents or arrangements may be
effected. If, on an Option Closing Date, any Underwriter or Underwriters shall
fail or refuse to purchase Additional Shares and the aggregate number of
Additional Shares with respect to which such default occurs is more than
one-tenth of the aggregate number of Additional Shares to be purchased on such
date, the non-defaulting Underwriters shall have the option to (i) terminate
their obligation hereunder to purchase such Additional Shares or (ii) purchase
not less than the number of Additional Shares that such non-defaulting
Underwriters would have been obligated to purchase on such date in the absence
of such default. Any action taken under this paragraph shall not relieve any
defaulting Underwriter from liability in respect of any default of any such
Underwriter under this Agreement.

      SECTION 10. MISCELLANEOUS. Notices given pursuant to any provision of this
Agreement shall be addressed as follows: (i) if to the Company, to U S Liquids
Inc., 411 N. Sam Houston Parkway East, Suite 400, Houston, Texas 77060-3545 and
(ii) if to any Underwriter or to you, to you c/o Donaldson, Lufkin & Jenrette

York 10172, Attention: Syndicate Department, or in any case to such other
address as the person to be notified may have requested in writing.

      The respective indemnities, contribution agreements, representations,
warranties and other statements of the Company and the several Underwriters set
forth in or made pursuant to this Agreement shall remain operative and in full
force and effect, and will survive delivery of and payment for the Shares,
regardless of (i) any investigation, or statement as to the results thereof,
made by or on behalf of any Underwriter, the officers or directors of any
Underwriter, any person controlling any Underwriter, the Company, the officers
or directors of the Company or any person controlling the Company, (ii)
acceptance of the Shares and payment for them hereunder and (iii) termination of
this Agreement.

      If for any reason the Shares are not delivered by or on behalf of the
Company as provided herein (other than as a result of any termination of this
Agreement pursuant to Section 9), the Company agrees to reimburse the several
Underwriters for all out-of-pocket expenses (including the fees and
disbursements of counsel) incurred by them. Notwithstanding any termination of
this Agreement, the Company shall be liable for all expenses which it has agreed
to pay pursuant to Section 5(i) hereof. The Company also agrees to reimburse the
several Underwriters, their directors and officers and any persons controlling
any of the Underwriters for any and all fees and expenses (including, without
limitation, the fees disbursements of counsel) incurred by them in connection
with enforcing their rights hereunder (including, without limitation, pursuant
to Section 7 hereof).

      Except as otherwise provided, this Agreement has been and is made solely
for the benefit of and shall be binding upon the Company, the Underwriters, the
Underwriters' directors and officers, any controlling persons referred to
herein, the Company's directors and the Company's officers who sign the
Registration Statement and their respective successors and assigns, all as and
to the extent provided in this Agreement, and no other person shall acquire or
have any right under or by virtue of this Agreement. The term "successors and
assigns" shall not include a purchaser of any of the Shares from any of the
several Underwriters merely because of such purchase.

      This Agreement shall be governed and construed in accordance with the laws
of the State of New York.

<PAGE>
Bank shall have any obligation to the Company or any Bank other than to confirm
that any documents required to be delivered under such Letter of Credit appear
to have been delivered and appear to comply on their face with the requirements
of such Letter of Credit. Any action taken or omitted to be taken by an Issuing
Bank under or in connection with any Letter of Credit, if taken or omitted in
the absence of gross negligence and willful misconduct, shall not impose upon
such Issuing Bank any liability to the Company or any Bank and shall not reduce
or impair the Company's reimbursement obligations set forth in SECTION 2.3.3 or
the obligations of the Banks pursuant to SECTION 2.3.5.

the account of such Issuing Bank, in full or partial payment of the purchase
price of its participation in such Letter of Credit, its pro rata share
(according to its Percentage) of such payment or disbursement (but no such

each other Bank thereof. Each other Bank irrevocably and unconditionally agrees
to so pay to the Agent in immediately available funds for the applicable Issuing
Bank's account the amount of such other Bank's Percentage of such payment or
disbursement. If and to the extent any Bank shall not have made such amount
available to the Agent by 2:00 P.M., Chicago time, on the Business Day on which
such Bank receives notice from the Agent of such payment or disbursement (it
being understood that any such notice received after noon, Chicago time, on any
Business Day shall be deemed to have been received on the next following
Business Day), such Bank agrees to pay interest on such amount to the Agent for
the applicable Issuing Bank's account forthwith on demand for each day from the
date such amount was to have been delivered to the Agent to the date such amount
is paid, at a rate per annum equal to (a) for the first three days after demand,
the Federal Funds Rate from time to time in effect and (b) thereafter, the Base
Rate from time to time in effect. Any Bank's failure to make available to the
Agent its Percentage of any such payment or disbursement shall not relieve any
other Bank of its obligation hereunder to make available to the Agent such other
Bank's Percentage of such payment, but no Bank shall be responsible for the
failure of any other Bank to make available to the Agent such other Bank's
Percentage of any such payment or disbursement.

        2.4  SWING LINE LOANS.

        2.4.1 SWING LINE LOANS. Subject to the terms and conditions of this
Agreement, the Swing Line Bank may from time to time, in its discretion, make
loans to the Company (collectively the "SWING LINE LOANS" and individually each
a "SWING LINE LOAN") in accordance with this SECTION 2.4 in an aggregate amount
not at any time exceeding $5,000,000; PROVIDED that the Total Outstandings shall
not at any time exceed the Commitment Amount. Amounts borrowed under this
SECTION 2.4 may be borrowed, repaid and (subject to the agreement of the Swing
Line Bank) reborrowed until the Termination Date.

        2.4.2 SWING LINE LOAN PROCEDURES. The Company shall give written or
telephonic notice to the Agent (which shall promptly inform the Swing Line Bank)
of each proposed Swing Line Loan not later than 12:00 noon, Chicago time, on the
proposed date of such Swing Line Loan. Each such notice shall be effective upon
receipt by the Agent and shall specify the date and amount of such Swing Line
Loan, which shall be not less than $100,000 or a higher integral multiple
thereof. So long as the Swing Line Bank has not received written notice that the
conditions precedent set forth in SECTION 11 with respect to the making of such
Swing Line Loan have not been satisfied, the Swing Line Bank may make the
requested Swing Line Loan. If the Swing Line Bank agrees to make the requested
Swing Line Loan, the Swing Line Bank shall pay over the requested amount to the
Company on the requested borrowing date. Concurrently with the making of any
Swing Line Loan, the Swing Line Bank shall be deemed to have sold and
transferred, and each other Bank shall be deemed to have purchased and received
from the Swing Line Bank, an undivided interest and participation to the extent
of such other Bank's Percentage in such Swing Line Loan (but such participation
shall remain unfunded until required to be funded pursuant to SECTION 2.4.3).

        2.4.3 REFUNDING OF, OR FUNDING OF PARTICIPATIONS IN, SWING LINE LOANS.
The Swing Line Bank may at any time, in its sole discretion, on behalf of the
Company (which hereby irrevocably authorizes the Swing Line Bank to act on its
behalf) deliver a notice to the Agent requesting that each Bank (including the
Swing Line Bank in its individual capacity) make a Revolving Loan (which shall
be a Floating Rate Loan) in such Bank's Percentage of the aggregate amount of
Swing Line Loans outstanding on such date for the purpose of repaying all Swing
Line Loans (and, upon receipt of the proceeds of such Revolving Loans, the Agent
shall apply such proceeds to repay Swing Line Loans); PROVIDED that if the
conditions precedent to a borrowing of Revolving Loans are not then satisfied or
for any other reason the Banks may not then make Revolving Loans, then instead
of making Revolving Loans each Bank (other than the Swing Line Bank) shall
become immediately obligated to fund its participation in all outstanding Swing
Line Loans

                                       26
<PAGE>
and shall pay to the Agent for the account of the Swing Line Bank an amount
equal to such Bank's Percentage of such Swing Line Loans. If and to the extent
any Bank shall not have made such amount available to the Agent by 2:00 P.M.,
Chicago time, on the Business Day on which such Bank receives notice from the
Agent of its obligation to fund its participation in Swing Line Loans (it being
understood that any such notice received after 12:00 noon, Chicago time, on any
Business Day shall be deemed to have been received on the next following
Business Day), such Bank agrees to pay interest on such amount to the Agent for
the Swing Line Bank's account forthwith on demand for each day from the date
such amount was to have been delivered to the Agent to the date such amount is
paid, at a rate per annum equal to (a) for the first three days after demand,
the Federal Funds Rate from time to time in effect and (b) thereafter, the Base
Rate from time to time in effect. Any Bank's failure to make available to the
Agent its Percentage of the amount of all outstanding Swing Line Loans shall not
relieve any other Bank of its obligation hereunder to make available to the
Agent such other Bank's Percentage of such amount, but no Bank shall be
responsible for the failure of any other Bank to make available to the Agent
such other Bank's Percentage of any such amount.

        2.4.4 REPAYMENT OF PARTICIPATIONS. Upon (and only upon) receipt by the
Agent for the account of the Swing Line Bank of immediately available funds from
or on behalf of the Company (a) in reimbursement of any Swing Line Loan with
respect to which a Bank has paid the Agent for the account of the Swing Line
Bank the amount of such Bank's participation therein or (b) in payment of any
interest on a Swing Line Loan, the Agent will pay to such Bank its pro rata
share (according to its Percentage) thereof (and the Swing Line Bank shall
receive the amount otherwise payable to any Bank which did not so pay the Agent
the amount of such Bank's participation in such Swing Line Loan).

        2.4.5 PARTICIPATION OBLIGATIONS UNCONDITIONAL. (a) Each Bank's
obligation to make available to the Agent for the account of the Swing Line Bank
the amount of its participation interest in all Swing Line Loans as provided in
SECTION 2.4.3 shall be absolute and unconditional and shall not be affected by
any circumstance, including (i) any set-off, counterclaim, recoupment, defense
or other right which such Bank may have against the Swing Line Bank or any other
Person, (ii) the occurrence or continuance of an Event of Default or Unmatured
Event of Default, (iii) any adverse change in the condition (financial or
otherwise) of the Company or any Subsidiary thereof, (iv) any termination of the
Commitments or (v) any other circumstance, happening or event whatsoever.

        (b) Notwithstanding the provisions of CLAUSE (a) above, no 

                                       27
<PAGE>
Bank shall be required to purchase a participation interest in any Swing Line
Loan if, prior to the making by the Swing Line Bank of such Swing Line Loan, the
Swing Line Bank received written notice specifying that one or more of the
conditions precedent to the making of such Swing Line Loan were not satisfied
and, in fact, such conditions precedent were not satisfied at the time of the
making of such Swing Line Loan.

        2.5 COMMITMENTS SEVERAL. The failure of any Bank to make a requested
Loan on any date shall not relieve any other Bank of its obligation (if any) to
make a Loan on such date, but no Bank shall be responsible for the failure of
any other Bank to make any Loan to be made by such other Bank.

        2.6 CERTAIN CONDITIONS. Notwithstanding any other provision of this
Agreement, no Bank shall have an obligation to make any Loan, or to permit the
continuation of or any conversion into any Eurodollar Loan, and no Issuing Bank
shall have any obligation to issue any Letter of Credit, if an Event of Default
or Unmatured Event of Default exists.

        SECTION 3  NOTES EVIDENCING LOANS.

        3.1 NOTES. The Loans of each Bank shall be evidenced by a promissory
note (each a "NOTE") substantially in the form set forth in EXHIBIT A, with
appropriate insertions, payable to the order of such Bank in a face principal
amount equal to such Bank's Percentage of the Commitment Amount (or, in the case
of the Swing Line Bank, an amount equal to the maximum principal amount of all
Revolving Loans and Swing Line Loans which the Swing Line Bank may at any time
have outstanding hereunder).

        3.2 RECORDKEEPING. Each Bank shall record in its records, or at its
option on the schedule attached to its Note, the date and amount of each Loan
made by such Bank, each repayment or conversion thereof and, in the case of each
Eurodollar Loan, the dates on which each Interest Period for such Loan shall
begin and end. The aggregate unpaid principal amount so recorded shall be
rebuttable presumptive evidence of the principal amount owing and unpaid on such
Note. The failure to so record any such amount or any error in so recording any
such amount shall not, however, limit or otherwise affect the obligations of the
Company hereunder or under any Note to repay the principal amount of the Loans 
evidenced by such Note together with all interest accruing thereon.

        SECTION 4  INTEREST.

        4.1 INTEREST RATES. The Company promises to pay interest on the unpaid
principal amount of each Loan for the period commencing on the date of such Loan
until such Loan is paid in 

                                       28
<PAGE>
full as follows:

               (a) at all times while such Loan is a Floating Rate Loan, at a
        rate per annum equal to the sum of the Base Rate from time to time in
        effect plus the Floating Rate Margin from time to time in effect;

               (b) at all times while such Loan is a Eurodollar Loan, at a rate
        per annum equal to the sum of the Eurodollar Rate (Reserve Adjusted)
        applicable to each Interest Period for such Loan plus the Eurodollar
        Margin from time to time in effect; and

               (c) at all times while such Loan is a Swing Line Loan, at a rate
        per annum separately agreed to by the Company and the Swing Line Bank
        from time to time (provided that if at any time the Banks are obligated
        to fund participations in Swing Line Loans pursuant to SECTION 2.4.3,
        all of such Swing Line Loans shall bear interest, from the date the
        obligation to fund such participations first arises to the date such
        Swing Line Loans are paid in full, at a rate per annum equal to the sum
        of the Base Rate from time to time in effect plus the Floating Rate
        Margin from time to time in effect);

PROVIDED, HOWEVER, that at any time an Event of Default exists, the interest
rate applicable to each Loan shall be increased by 2%.

        4.2 INTEREST PAYMENT DATES. Accrued interest on each Floating Rate Loan
and Swing Line Loan shall be payable in arrears on the last Business Day of each
calendar quarter and at maturity. Accrued interest on each Eurodollar Loan shall
be payable on the last day of each Interest Period relating to such Loan (and,
in the case of a Eurodollar Loan with a six-month Interest Period, on the
three-month anniversary of the first day of such Interest Period) and at
maturity. After maturity, accrued interest on all Loans shall be payable on
demand.

        4.3 INTEREST PERIODS. Each "Interest Period" for a Eurodollar Loan shall
commence on the date such Eurodollar Loan is made or converted from a Floating
Rate Loan, or on the expiration of the immediately preceding Interest Period for
such Eurodollar Loan, and shall end on the date which is one, two, three or six
months thereafter (or, during the 60 days immediately following the Effective
Date, such other period of time as the Company and all Banks may agree upon), as
the Company may specify:

               (a) in the case of an Interest Period which commences on the date
        a Eurodollar Loan is made or converted from a 

                                       29
<PAGE>
        Floating Rate Loan, in the related notice of borrowing or conversion
        pursuant to SECTION 2.2.2 or 2.2.3, or

               (b) in the case of a succeeding Interest Period with respect to
        any Eurodollar Loan, by written notice or telephonic notice (followed
        immediately by written confirmation thereof) to the Agent not later than
        9:00 A.M., Chicago time, at least two Business Days prior to the first
        day of such succeeding Interest Period, it being understood that (i)
        each such notice shall be effective upon receipt by the Agent and (ii)
        if the Company fails to give such notice, such Loan shall automatically
        become a Floating Rate Loan at the end of its then-current Interest
        Period.

Each Interest Period that begins on a day for which there is no numerically
corresponding day in the appropriate subsequent calendar month shall end on the
last Business Day of the appropriate subsequent calendar month. Each Interest
Period which would otherwise end on a day which is not a Business Day shall end
on the immediately succeeding Business Day (unless such immediately succeeding
Business Day is the first Business Day of a calendar month, in which case such
Interest Period shall end on the immediately preceding Business Day). The
Company may not select any Interest Period for a Eurodollar Loan (a) which would
end after the scheduled Termination Date or (b) which would result in the
aggregate principal amount of all Eurodollar Loans having Interest Periods
ending after a date on which the Commitment Amount is scheduled to be reduced
pursuant to SECTION 6.1.2, PLUS the Stated Amount of all Letters of Credit
having expiration dates after the date of such scheduled reduction, being in
excess of the Commitment Amount which is scheduled to be in effect after giving
effect to such scheduled reduction.

        4.4 SETTING AND NOTICE OF EURODOLLAR RATES. The applicable Eurodollar
Rate for each Interest Period shall be determined by the Agent, and notice
thereof shall be given by the Agent promptly to the Company and each Bank. Each
determination of the applicable Eurodollar Rate by the Agent shall be conclusive
and binding upon the parties hereto, in the absence of demonstrable error. The
Agent shall, upon written request of the Company or any Bank, deliver to the
Company or such Bank a statement showing the computations used by the Agent in
determining any applicable Eurodollar Rate hereunder.

        4.5 COMPUTATION OF INTEREST. All determinations of interest for Floating
Rate Loans and Swing Line Loans when the Base Rate is determined by the
Reference Rate shall be made on the basis of a year of 365 or 366 days, as the
case may be, and the actual number of days elapsed. All other computations of
interest shall be computed for the actual number of days elapsed on the basis of
a year of 360 days. The applicable interest rate for each Floating Rate Loan
shall change simultaneously with each

                                       30
<PAGE>
change in the Base Rate.

        SECTION 5  FEES.

        5.1 NON-USE FEE. The Company agrees to pay to the Agent for the account
of each Bank a non-use fee, for the period from the Effective Date to the
Termination Date, at the rate per annum in effect from time to time pursuant to
SCHEDULE 1.1 of the daily average of the unused amount of such Bank's Percentage
of the Commitment Amount. For purposes of calculating usage under this Section,
the Commitment Amount shall be deemed used to the extent of the aggregate
principal amount of all outstanding Loans plus the undrawn amount of all Letters
of Credit. Such non-use fee shall be payable in arrears on the last Business Day
of each calendar quarter and on the Termination Date for any period then ending
for which such non-use fee shall not have theretofore been paid. The non-use fee
shall be computed for the actual number of days elapsed on the basis of a year
of 360 days.

        5.2 LETTER OF CREDIT FEES. (a) The Company agrees to pay to the Agent
for the account of the Banks pro rata according to their respective Percentages
a letter of credit fee for each Letter of Credit in an amount equal to the rate
per annum in effect from time to time pursuant to SCHEDULE 1.1 of the undrawn
amount of such Letter of Credit (computed for the actual number of days elapsed
on the basis of a year of 360 days); PROVIDED that the rate applicable to each
Letter of Credit shall be increased by 2% at any time that an Event of Default
exists. Such letter of credit fee shall be payable in arrears on the last
Business Day of each calendar quarter and on the Termination Date for the period
from the date of the issuance of each Letter of Credit to the date such payment
is due or, if earlier, the date on which such Letter of Credit expired or was
terminated.

        (b) In addition, with respect to each Letter of Credit, the Company
agrees to pay to the applicable Issuing Bank, for its own account, (i) such fees
and expenses as such Issuing Bank customarily requires in connection with the
issuance, negotiation, processing and/or administration of letters of credit in
similar situations and (ii) a letter of credit fee in the amount separately
agreed to by the Company and such Issuing Bank.

        5.3 ARRANGEMENT AND AGENT'S FEES. The Company agrees to pay to the
Arranger and the Agent such arrangement and agent's fees as are mutually agreed
to from time to time by the Company and the Agent.

        SECTION 6     REDUCTION AND TERMINATION OF THE COMMITMENTS;
                      PREPAYMENTS.

                                       31
<PAGE>
        6.1 REDUCTION OR TERMINATION OF THE COMMITMENTS.

               6.1.1 VOLUNTARY REDUCTION OR TERMINATION OF THE COMMITMENTS. The
Company may from time to time on at least five Business Days' prior written
notice received by the Agent (which shall promptly advise each Bank thereof)
permanently reduce the Commitment Amount to an amount not less than the Total
Outstandings. Any such reduction shall be in an amount not less than $5,000,000
or a higher integral multiple of $1,000,000. The Company may at any time on like
notice terminate the Commitments upon payment in full of all Loans and all other
obligations of the Company hereunder and cash collateralization in full,
pursuant to documentation in form and substance reasonably satisfactory to the
Banks, of all obligations arising with respect to the Letters of Credit.

               6.1.2 MANDATORY REDUCTIONS OF COMMITMENTS. If the Equity Offering
is not completed on or before December 31, 1998, the Commitment Amount shall be
reduced by $3,750,000 on January 1, 1999 and on each April 1, July 1, October 1
and January 1 thereafter until the Termination Date. The scheduled reductions
under this Section shall not be reduced by any reductions under SECTION 6.1.1.

               6.1.3 ALL REDUCTIONS OF THE COMMITMENTS. All reductions of the
Commitment Amount shall reduce the Commitments pro rata among the Banks
according to their respective Percentages.

        6.2    PREPAYMENTS.

               6.2.1 VOLUNTARY PREPAYMENTS. The Company may from time to time
prepay the Loans in whole or in part, PROVIDED that the Company shall give the
Agent (which shall promptly advise each Bank) notice thereof not later than
10:00 A.M. (or, in the case of prepayment of Swing Line Loans, 12:00 noon),
Chicago time, on the day of such prepayment (which shall be a Business Day),
specifying the Loans to be prepaid and the date and amount of prepayment.

               6.2.2  MANDATORY PAYMENTS.  If, after giving effect to
any reduction of the Commitment Amount pursuant to SECTION 6.1.2, the Total
Outstandings exceed the Commitment Amount, then concurrently with such reduction
the Company shall make a prepayment of the Loans in an amount equal to or
greater than such excess (it being understood that if all outstanding Loans have
been prepaid and the Stated Amount of all Letters of Credit exceeds such reduced
Commitment Amount, the Company shall provide cash collateral in an amount equal
to such excess pursuant to documentation reasonably satisfactory to the Agent).


                                       32
<PAGE>
               6.2.3 ALL PREPAYMENTS. Each partial prepayment shall be in a
principal amount of $100,000 or a higher integral multiple thereof. Any
prepayment of a Eurodollar Loan on a day other than the last day of an Interest
Period therefor shall include interest on the principal amount being repaid and
shall be subject to SECTION 8.4.

        SECTION 7  MAKING AND PRORATION OF PAYMENTS; SETOFF; TAXES.

        7.1 MAKING OF PAYMENTS. All payments of principal of or interest on the
Notes, and of all non-use fees and Letter of Credit fees, shall be made by the
Company to the Agent in immediately available funds at the office specified by
the Agent not later than noon, Chicago time, on the date due; and funds received
after that hour shall be deemed to have been received by the Agent on the next
following Business Day. The Agent shall promptly remit to each Bank or other
holder of a Note its share of all such payments received in collected funds by
the Agent for the account of such Bank or holder.

        All payments under SECTION 8.1 shall be made by the Company directly to
the Bank entitled thereto.

        7.2 APPLICATION OF CERTAIN PAYMENTS. Each payment of principal shall be
applied to such Loans as the Company shall direct by notice to be received by
the Agent on or before the date of such payment or, in the absence of such
notice, as the Agent shall determine in its discretion. Concurrently with each
remittance to any Bank of its share of any such payment, the Agent shall advise
such Bank as to the application of such payment.

        7.3 DUE DATE EXTENSION. If any payment of principal or interest with
respect to any of the Notes, or of non-use fees or Letter of Credit fees, falls
due on a day which is not a Business Day, then such due date shall be extended
to the immediately following Business Day (unless, in the case of a Eurodollar
Loan, such immediately following Business Day is the first Business Day of a
calendar month, in which case such date shall be the immediately preceding
Business Day) and, in the case of principal, additional interest shall accrue
and be payable for the period of any such extension.

        7.4 SETOFF. The Company agrees that the Agent and each Bank have all
rights of set-off and bankers' lien provided by applicable law, and in addition
thereto, the Company agrees that at any time any Event of Default exists, the
Agent and each Bank may apply to the payment of any obligations of the Company
hereunder, whether or not then due, any and all balances, credits, deposits,
accounts or moneys of the Company then or thereafter with the Agent or such
Bank.

                                       33
<PAGE>
        7.5 PRORATION OF PAYMENTS. If any Bank shall obtain any payment or other
recovery (whether voluntary, involuntary, by application of offset or otherwise,
but excluding any payment pursuant to SECTION 8.7 or 14.9 or any payment to the
Swing Line Bank in respect of a Swing Line Loan) on account of principal of or
interest on any Note (or on account of its participation in any Letter of Credit
or Swing Line Loan) in excess of its pro rata share of payments and other
recoveries obtained by all Banks on account of principal of and interest on
Notes (or such participation) then held by them, such Bank shall purchase from
the other Banks such participation in the Notes (or sub-participation in Letters
of Credit or Swing Line Loans) held by them as shall be necessary to cause such
purchasing Bank to share the excess payment or other recovery ratably with each
of them; PROVIDED, HOWEVER, that if all or any portion of the excess payment or
other recovery is thereafter recovered from such purchasing Bank, the purchase
shall be rescinded and the purchase price restored to the extent of such
recovery.

        7.6 TAXES. All payments of principal of, and interest on, the Loans and
all other amounts payable hereunder shall be made free and clear of and without
deduction for any present or future income, excise, stamp or franchise taxes and
other taxes, fees, duties, withholdings or other charges of any nature
whatsoever imposed by any taxing authority, but excluding franchise taxes and
taxes imposed on or measured by any Bank's net income or receipts (all
non-excluded items being called "TAXES"). If any withholding or deduction from
any payment to be made by the Company hereunder is required in respect of any
Taxes pursuant to any applicable law, rule or regulation, then the Company will:

               (a)  pay directly to the relevant authority the full
        amount required to be so withheld or deducted;

               (b) promptly forward to the Agent an official receipt or other
        documentation satisfactory to the Agent evidencing such payment to such
        authority; and

               (c) pay to the Agent for the account of the Banks such additional
        amount or amounts as is necessary to ensure that the net amount actually
        received by each Bank will equal the full amount such Bank would have 
        received had no such withholding or deduction been required.

Moreover, if any Taxes are directly asserted against the Agent or any Bank with
respect to any payment received by the Agent or such Bank hereunder, the Agent
or such Bank may pay such Taxes and the Company will promptly pay such
additional amounts (including any penalty, interest and expense) as is necessary
in order that the net amount received by such Person after the 

                                       34
<PAGE>
payment of such Taxes (including any Taxes on such additional amount) shall
equal the amount such Person would have received had such Taxes not been
asserted.

        If the Company fails to pay any Taxes when due to the appropriate taxing
authority or fails to remit to the Agent, for the account of the respective
Banks, the required receipts or other required documentary evidence, the Company
shall indemnify the Banks for any incremental Taxes, interest or penalties that
may become payable by any Bank as a result of any such failure. For purposes of
this SECTION 7.6, a distribution hereunder by the Agent or any Bank to or for
the account of any Bank shall be deemed a payment by the Company.

        Upon the request from time to time of the Company or the Agent, each
Bank that is organized under the laws of a jurisdiction other than the United
States of America shall execute and deliver to the Company and the Agent one or
more (as the Company or the Agent may reasonably request) United States Internal
Revenue Service Forms 4224 or Forms 1001 or such other forms or documents,
appropriately completed, as may be applicable to establish the extent, if any,
to which a payment to such Bank is exempt from withholding or deduction of
Taxes.

        The obligations of the Company under this SECTION 7.6 are subject to the
limitation set out in SECTION 14.9.1.

        SECTION 8  INCREASED COSTS; SPECIAL PROVISIONS FOR
EURODOLLAR LOANS.

        8.1 INCREASED COSTS. (a) If, after the date hereof, the adoption of any
applicable law, rule or regulation, or any change therein, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Bank (or any Eurodollar Office of such Bank) with
any request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency

               (A) shall subject any Bank (or any Eurodollar Office of such
        Bank) to any tax, duty or other charge with respect to its Eurodollar
        Loans, its Note or its obligation to make Eurodollar Loans, or shall
        change the basis of taxation of payments to any Bank of the principal of
        or interest on its Eurodollar Loans or any other amounts due under this
        Agreement in respect of its Eurodollar Loans or its obligation to make
        Eurodollar Loans (except for changes in the rate of tax on the overall
        net income of such Bank or its Eurodollar Office imposed by the
        jurisdiction in which such Bank's principal executive office or
        Eurodollar Office is located); or


                                       35
<PAGE>
               (B) shall impose, modify or deem applicable any reserve
        (including any reserve imposed by the Board of Governors of the Federal
        Reserve System, but excluding any reserve included in the determination
        of interest rates pursuant to SECTION 4), special deposit or similar
        requirement against assets of, deposits with or for the account of, or
        credit extended by any Bank (or any Eurodollar Office of such Bank); or

               (C) shall impose on any Bank (or its Eurodollar Office) any other
        condition affecting its Eurodollar Loans, its Note or its obligation to
        make Eurodollar Loans;

and the result of any of the foregoing is to increase the cost to (or in the
case of Regulation D of the Board of Governors of the Federal Reserve System, to
impose a cost on) such Bank (or any Eurodollar Office of such Bank) of making or
maintaining any Eurodollar Loan, or to reduce the amount of any sum received or
receivable by such Bank (or its Eurodollar Office) under this Agreement or under
its Note with respect thereto, then within 10 days after demand by such Bank
(which demand shall be accompanied by a statement setting forth the basis for
such demand and a calculation of the amount thereof in reasonable detail, a copy
of which shall be furnished to the Agent), the Company shall pay directly to
such Bank such additional amount as will compensate such Bank for such increased
cost or such reduction.

        (b) If any Bank shall reasonably determine that the adoption or phase-in
of any applicable law, rule or regulation regarding capital adequacy, or any
change therein, or any change in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Bank or any
Person controlling such Bank with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on such Bank's or such controlling Person's capital as a consequence of
such Bank's obligations hereunder or under any Letter of Credit to a level below
that which such Bank or such controlling Person could have achieved but for such
adoption, change or compliance (taking into consideration such Bank's or such
controlling Person's policies with respect to capital adequacy) by an amount
deemed by such Bank or such controlling Person to be material, then from time to
time, within 10 days after demand by such Bank (which demand shall be
accompanied by a statement setting forth the basis for such demand and a
calculation of the amount thereof in reasonable detail, a copy of which shall be
furnished to the Agent), the Company shall pay to such Bank such additional
amount or amounts 

                                       36
<PAGE>
as will compensate such Bank or such controlling Person for such reduction.

        8.2  BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR
UNFAIR.  If with respect to any Interest Period:

               (a) deposits in Dollars (in the applicable amounts) are not being
        offered to the Agent in the interbank eurodollar market for such
        Interest Period, or the Agent otherwise reasonably determines (which
        determination, if made in good faith, shall be binding and conclusive on
        the Company) that by reason of circumstances affecting the interbank
        eurodollar market adequate and reasonable means do not exist for
        ascertaining the applicable Eurodollar Rate; or

               (b) Banks having an aggregate Percentage of 40% or more advise
        the Agent that the Eurodollar Rate (Reserve Adjusted) as determined by
        the Agent will not adequately and fairly reflect the cost to such Banks
        of maintaining or funding such Eurodollar Loans for such Interest Period
        (taking into account any amount to which such Banks may be entitled
        under SECTION 8.1) or that the making or funding of Eurodollar Loans has
        become impracticable as a result of an event occurring after the date of
        this Agreement which in the opinion of such Banks materially affects
        such Loans;

THEN the Agent shall promptly notify the other parties thereof and, so long as
such circumstances shall continue, (i) no Bank shall be under any obligation to
make or convert into Eurodollar Loans and (ii) on the last day of the current
Interest Period for each Eurodollar Loan, such Loan shall, unless then repaid in
full, automatically convert to a Floating Rate Loan.

        8.3 CHANGES IN LAW RENDERING EURODOLLAR LOANS UNLAWFUL. In the event
that any change in (including the adoption of any new) applicable laws or
regulations, or any change in the interpretation of applicable laws or
regulations by any governmental or other regulatory body charged with the
administration thereof, should make it (or in the good faith judgment of any
Bank cause a substantial question as to whether it is) unlawful for any Bank to
make, maintain or fund Eurodollar Loans, then such Bank shall promptly notify
each of the other parties hereto and, so long as such circumstances shall
continue, (a) such Bank shall have no obligation to make or convert into
Eurodollar Loans (but shall make Floating Rate Loans concurrently with the
making of or conversion into Eurodollar Loans by the Banks which are not so
affected, in each case in an amount equal to such Bank's pro rata share of all
Eurodollar Loans which would be made or converted into at such time in the
absence of such circumstances) and (b) on the last day of the current Interest

                                       37
<PAGE>
Period for each Eurodollar Loan of such Bank (or, in any event, on such earlier
date as may be required by the relevant law, regulation or interpretation), such
Eurodollar Loan shall, unless then repaid in full, automatically convert to a
Floating Rate Loan. Each Floating Rate Loan made by a Bank which, but for the
circumstances described in the foregoing sentence, would be a Eurodollar Loan
(an "AFFECTED LOAN") shall remain outstanding for the same period as the Group
of Eurodollar Loans of which such Affected Loan would be a part absent such
circumstances.

        8.4 FUNDING LOSSES. The Company hereby agrees that upon demand by any
Bank (which demand shall be accompanied by a statement setting forth the basis
for the amount being claimed, a copy of which shall be furnished to the Agent),
the Company will indemnify such Bank against any net loss or expense which such
Bank may sustain or incur (including any net loss or expense incurred by reason
of the liquidation or reemployment of deposits or other funds acquired by such
Bank to fund or maintain any Eurodollar Loan), as reasonably determined by such
Bank, as a result of (a) any payment, prepayment or conversion of any Eurodollar
Loan of such Bank on a date other than the last day of an Interest Period for
such Loan (including any conversion pursuant to SECTION 8.3) or (b) any failure
of the Company to borrow or convert any Loan on a date specified therefor in a
notice of borrowing or conversion pursuant to this Agreement. For this purpose,
all notices to the Agent pursuant to this Agreement shall be deemed to be
irrevocable.

        8.5 RIGHT OF BANKS TO FUND THROUGH OTHER OFFICES. Each Bank may, if it
so elects, fulfill its commitment as to any Eurodollar Loan by causing a foreign
branch or affiliate of such Bank to make such Loan, PROVIDED that in such event
for the purposes of this Agreement such Loan shall be deemed to have been made
by such Bank and the obligation of the Company to repay such Loan shall
nevertheless be to such Bank and shall be deemed held by it, to the extent of
such Loan, for the account of such branch or affiliate.

        8.6 DISCRETION OF BANKS AS TO MANNER OF FUNDING. Notwithstanding any
provision of this Agreement to the contrary, each Bank shall be entitled to fund
and maintain its funding of all or any part of its Loans in any manner it sees
fit, it being understood, however, that for the purposes of this Agreement all
determinations hereunder shall be made as if such Bank had actually funded and
maintained each Eurodollar Loan during each Interest Period for such Loan
through the purchase of deposits having a maturity corresponding to such
Interest Period and bearing an interest rate equal to the Eurodollar Rate for
such Interest Period.

        8.7 MITIGATION OF CIRCUMSTANCES; REPLACEMENT OF AFFECTED 

                                       38
<PAGE>
BANK. (a) Each Bank shall promptly notify the Company and the Agent of any event
of which it has knowledge which will result in, and will use reasonable
commercial efforts available to it (and not, in such Bank's good faith judgment,
otherwise disadvantageous to such Bank) to mitigate or avoid, (i) any obligation
by the Company to pay any amount pursuant to SECTION 7.6 or 8.1 or (ii) the
occurrence of any circumstances of the nature described in SECTION 8.2 or 8.3
(and, if any Bank has given notice of any such event described in CLAUSE (I) or
(II) above and thereafter such event ceases to exist, such Bank shall promptly
so notify the Company and the Agent). Without limiting the foregoing, each Bank
will designate a different funding office if such designation will avoid (or
reduce the cost to the Company of) any event described in CLAUSE (I) or (II) of
the preceding sentence and such designation will not, in such Bank's sole
judgment, be otherwise disadvantageous to such Bank.

        (b) At any time any Bank is an Affected Bank, the Company may replace
such Affected Bank as a party to this Agreement with one or more other bank(s)
or financial institution(s) reasonably satisfactory to the Agent (and upon
notice from the Company such Affected Bank shall assign pursuant to an
Assignment Agreement, and without recourse or warranty, its Commitment, its
Loans, its Note, its participation in Letters of Credit, and all of its other
rights and obligations hereunder to such replacement bank(s) or other financial
institution(s) for a purchase price equal to the sum of the principal amount of
the Loans so assigned, all accrued and unpaid interest thereon, its ratable
share of all accrued and unpaid non-use fees and Letter of Credit fees, any
amounts payable under SECTION 8.4 as a result of such Bank receiving payment of
any Eurodollar Loan prior to the end of an Interest Period therefor and all
other obligations owed to such Affected Bank hereunder).

        8.8 CONCLUSIVENESS OF STATEMENTS; SURVIVAL OF PROVISIONS. Determinations
and statements of any Bank pursuant to SECTION 8.1, 8.2, 8.3 or 8.4 shall be
conclusive absent demonstrable error. Banks may use reasonable averaging and
attribution methods in determining compensation under SECTIONS 8.1 and 8.4, and
the provisions of such Sections shall survive repayment of the Loans,
cancellation of the Notes, cancellation or expiration of the Letters of Credit
and any termination of this Agreement.


        SECTION 9  WARRANTIES.

        To induce the Agent and the Banks to enter into this Agreement and to

of the State of Delaware; each Subsidiary is a corporation duly organized,
validly existing and in good standing under the laws of the state of its
incorporation; and the Company and each Subsidiary is duly qualified to do
business in each jurisdiction where the nature of its business makes such

full power and authority to own its property and conduct its business as
presently conducted by it.

        9.2 AUTHORIZATION; NO CONFLICT. The execution and delivery by the
Company of this Agreement and each other Loan Document to which it is a party,

        9.3 VALIDITY AND BINDING NATURE. Each of this Agreement and each other

enforceability of creditors' rights generally and to general principles of
equity; and each Loan Document to which any Guarantor is a party is, or upon the
execution and delivery thereof by such Guarantor will be, the legal, valid and
binding obligation of such Guarantor, enforceable against such Guarantor in

Company or any 

                                       43
<PAGE>
Subsidiary must conduct a remedial investigation, removal, response action or
other activity pursuant to any Environmental Law; or (d) of any Environmental
Claim.

there have been no Releases or threatened Releases of Hazardous Substances on,
upon, into or from any real property or other assets of the Company or any
Subsidiary, which Releases singly or in the aggregate might reasonably be

assets; (iv) to the Company's actual knowledge, there have been no Releases on,
upon, from or into any real property in the vicinity of the real property or
other assets of the Company or any Subsidiary which, through soil or groundwater
contamination, may have come to be located on, and which might reasonably be
expected to have a material adverse effect on the value of, the real property or
other assets of the Company or any Subsidiary; and (v) any Hazardous Substances
generated by the Company and its Subsidiaries have been transported offsite only
by properly licensed carriers and delivered only to treatment or disposal
facilities maintaining valid permits as required under applicable Environmental

Company's knowledge, operating in compliance with such permits and applicable
Environmental Laws.

               (d) INVESTIGATIONS. Except as set forth on SCHEDULE 9.15, the
Company and its Subsidiaries have taken all reasonable steps to investigate the
past and present condition and usage of the real property of the Company and its
Subsidiaries and the operations conducted by the Company and its Subsidiaries
with regard to environmental matters.

        9.16 YEAR 2000 PROBLEM. The Company and its Subsidiaries have reviewed
the areas within their business and operations which could be adversely affected
by, and have developed or are developing a program to address on a timely basis,
the "Year 2000 Problem" (that is, the risk that computer applications used by
the Company and its Subsidiaries may be unable to recognize and perform properly
date-sensitive functions involving certain dates prior to and any date after
December 31, 1999). Based on such 

                                       44
<PAGE>
review and program, the Company reasonably believes that the "Year 2000 Problem"
will not have a Material Adverse Effect.

        9.17 INFORMATION. All information heretofore or contemporaneously
herewith furnished in writing by the Company or any Subsidiary to any Bank for
purposes of or in connection with this Agreement and the transactions
contemplated hereby is, and all written information hereafter furnished by or on
behalf of the Company or any Subsidiary to any Bank pursuant hereto or in
connection herewith will be, true and accurate in every material respect on the
date as of which such information is dated or certified, and none of such
information is or will be incomplete by omitting to state any material fact
necessary to make such information not misleading in light of the circumstances
under which made (it being recognized by the Agent and the Banks that (a) any
projections and forecasts provided by the Company are based on good faith
estimates and assumptions believed by the Company to be reasonable as of the
date of the applicable projections or assumptions and that actual results during
the period or periods covered by any such projections and forecasts may differ
from projected or forecasted results and (b) any information provided by the
Company or any Subsidiary with respect to any Person or assets acquired or to be
acquired by the Company or any Subsidiary shall, for all periods prior to the

        SECTION 10  COVENANTS.

        Until the expiration or termination of the Commitments and thereafter
until all obligations of the Company hereunder and under the other Loan

expressly consent in writing, it will:

matters or, if something has come to their attention that caused them to believe
that the Company was not in compliance with any such provision, describing such

not directed primarily toward obtaining knowledge of such non-compliance); and

terms applicable to any Debt of the Company or any Subsidiary in an aggregate

Material Adverse Effect (except only to the extent that the existence of any
such default is being contested by the Company or such Subsidiary in good faith
and by appropriate proceedings and appropriate reserves have been made in
respect of such default).

other custodian is appointed for the Company or any Subsidiary or for a
substantial part of the property of any thereof and is not discharged within 60
days; or any bankruptcy, reorganization, debt arrangement, or other case or
proceeding under any bankruptcy or insolvency law, or any dissolution or 
liquidation proceeding (except the voluntary dissolution, not under any 
bankruptcy or insolvency law, of a Subsidiary), is commenced in respect of the
Company or any Subsidiary, and if such case or proceeding is not commenced by
the Company or such Subsidiary, it is consented to or acquiesced in by the
Company or such Subsidiary, or remains for 60 days undismissed; or the Company
or any Subsidiary takes any corporate action to authorize, or in furtherance of,
any of the foregoing.

(ii) a contribution failure occurs with respect to any Pension Plan sufficient
to give rise to a Lien under section 302(f) of ERISA; or (iii) there shall occur

withdrawal liability (without unaccrued interest) to Multiemployer Pension Plans
as a result of such withdrawal (including any outstanding withdrawal liability
that the Company and the Controlled Group have incurred on the date of such
withdrawal) exceeds $250,000.

        12.1.8 JUDGMENTS. Final judgments which exceed an aggregate of $250,000

the meaning of Section 13 or 14 of the Securities Exchange Act of 1934, but

hereunder shall become immediately due and payable and the Company shall become
immediately obligated to deliver to the Agent cash collateral in an amount equal
to the outstanding face amount of all Letters of Credit, all without
presentment, demand, protest or notice of any kind; and, if any other Event of
Default shall occur and be continuing, the Agent (upon written request of the
Required Banks) shall declare the Commitments (if they have not theretofore
terminated) to be terminated and/or declare all Notes and all other obligations
hereunder to be due and payable and/or demand that the Company immediately
deliver to the Agent cash collateral in amount equal to the outstanding face

                                       62
<PAGE>
immediately due and payable and/or the Company shall immediately become
obligated to deliver to the Agent cash collateral in an amount equal to the face
amount of all Letters of Credit, all without presentment, demand, protest or
notice of any kind. The Agent shall promptly advise the Company of any such
declaration, but failure to do so shall not impair the effect of such
declaration. Notwithstanding the foregoing, the effect as an Event of Default of
any event described in SECTION 12.1.1 or SECTION 12.1.4 may be waived by the
written concurrence of all of the Banks, and the effect as an Event of Default
of any other event described in this SECTION 12 may be waived by the written
concurrence of the Required Banks. Any cash collateral delivered hereunder shall
be held by the Agent (without liability for interest thereon) and applied to
obligations arising in connection with any drawing under a Letter of Credit.
After the expiration or termination of all Letters of Credit, such cash
collateral shall be applied by the Agent to any remaining obligations hereunder
and any excess shall be delivered to the Company or as a court of competent
jurisdiction may elect.

        SECTION 13  THE AGENT.

        13.1 APPOINTMENT AND AUTHORIZATION. (a) Each Bank hereby irrevocably
(subject to SECTION 13.9) appoints, designates and authorizes the Agent to take
such action on its behalf under the provisions of this Agreement and each other
Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Agent shall not have any duties or
responsibilities except those expressly set forth herein, nor shall the Agent
have or be deemed to have any fiduciary relationship with any Bank, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Agent.

        (b) Each Issuing Bank shall act on behalf of the Banks with respect to
any Letters of Credit issued by it and the documents associated therewith. Each
Issuing Bank shall have all of the benefits and immunities (i) provided to the
Agent in this SECTION 13 with respect to any acts taken or omissions suffered by
such Issuing Bank in connection with Letters of Credit issued by it or proposed
to be issued by it and the applications and agreements for letters of credit
pertaining to such Letters of Credit as fully as if the term "Agent", as used in
this SECTION 13, included such Issuing Bank with respect to such acts or
omissions and (ii) as additionally provided in this Agreement with respect to
the Issuing Banks.

matters pertaining to such duties. The Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects with
reasonable care.

        13.3 LIABILITY OF AGENT. None of the Agent-Related Persons shall (i) be
liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct),
or (ii) be responsible in any manner to any of the Banks for any recital,
statement, representation or warranty made by the Company or any Subsidiary or
Affiliate of the Company, or any officer thereof, contained in this Agreement or
in any other Loan Document, or in any certificate, report, statement or other
document referred to or provided for in, or received by the Agent under or in
connection with, this Agreement or any other Loan Document, or the validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Document, or for any failure of the Company or any other party to
any Loan Document to perform its obligations hereunder or thereunder. No
Agent-Related Person shall be under any obligation to any Bank to ascertain or
to inquire as to the observance or performance of any of the agreements
contained in, or conditions of, this Agreement or any other Loan Document, or to
inspect the properties, books or records of the Company or any of the Company's
Subsidiaries or Affiliates.

        13.4 RELIANCE BY AGENT. The Agent shall be entitled to rely, and shall
be fully protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel (including counsel to the
Company), independent accountants and other experts selected by the Agent. The
Agent shall be fully justified in failing or refusing to take any action under
this Agreement or any other Loan Document unless it 

                                       64
<PAGE>
shall first receive such advice or concurrence of the Required Banks as it deems
appropriate and, if it so requests, confirmation from the Banks of their
obligation to indemnify the Agent against any and all liability and expense
which may be incurred by it by reason of taking or continuing to take any such
action. The Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement or any other Loan Document in
accordance with a request or consent of the Required Banks and such request and
any action taken or failure to act pursuant thereto shall be binding upon all of
the Banks.

        13.5 NOTICE OF DEFAULT. The Agent shall not be deemed to have knowledge
or notice of the occurrence of any Event of Default or Unmatured Event of
Default except with respect to defaults in the payment of principal, interest
and fees required to be paid to the Agent for the account of the Banks, unless
the Agent shall have received written notice from a Bank or the Company
referring to this Agreement, describing such Event of Default or Unmatured Event
of Default and stating that such notice is a "notice of default". The Agent will
notify the Banks of its receipt of any such notice. The Agent shall take such
action with respect to such Event of Default or Unmatured Event of Default as
may be requested by the Required Banks in accordance with SECTION 12; PROVIDED,
HOWEVER, that unless and until the Agent has received any such request, the
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Event of Default or Unmatured Event of
Default as it shall deem advisable or in the best interest of the Banks.

        13.6 CREDIT DECISION. Each Bank acknowledges that none of the
Agent-Related Persons has made any representation or warranty to it, and that no
act by the Agent hereafter taken, including any review of the affairs of the
Company and its Subsidiaries, shall be deemed to constitute any representation
or warranty by any Agent-Related Person to any Bank. Each Bank represents to the
Agent that it has, independently and without reliance upon any Agent-Related
Person and based on such documents and information as it has deemed appropriate,
made its own appraisal of and investigation into the business, prospects,
operations, property, financial and other condition and creditworthiness of the
Company and its Subsidiaries, and all applicable bank regulatory laws relating
to the transactions contemplated hereby, and made its own decision to enter into
this Agreement and to extend credit to the Company hereunder. Each Bank also
represents that it will, independently and without reliance upon any
Agent-Related Person and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan 

                                       65
<PAGE>
Documents, and to make such investigations as it deems necessary to inform
itself as to the business, prospects, operations, property, financial and other
condition and creditworthiness of the Company. Except for notices, reports and
other documents expressly herein required to be furnished to the Banks by the
Agent, the Agent shall not have any duty or responsibility to provide any Bank
with any credit or other information concerning the business, prospects,
operations, property, financial or other condition or creditworthiness of the
Company which may come into the possession of any of the Agent-Related Persons.

        13.7 INDEMNIFICATION. Whether or not the transactions contemplated
hereby are consummated, the Banks shall indemnify upon demand the Agent-Related
Persons (to the extent not reimbursed by or on behalf of the Company and without
limiting the obligation of the Company to do so), pro rata, from and against any
and all Indemnified Liabilities; PROVIDED, HOWEVER, that no Bank shall be liable
for any payment to the Agent-Related Person of any portion of the Indemnified
Liabilities resulting solely from such Person's gross negligence or willful
misconduct. Without limitation of the foregoing, each Bank shall reimburse the
Agent upon demand for its ratable share of any costs or out-of-pocket expenses
(including reasonable fees of attorneys for the Agent (including the allocable
costs of internal legal services and all disbursements of internal counsel))
incurred by the Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement, any other Loan Document, or
any document contemplated by or referred to herein, to the extent that the Agent
is not reimbursed for such expenses by or on behalf of the Company. The
undertaking in this Section shall survive repayment of the Loans, cancellation
of the Notes, any foreclosure under, or any modification, release or discharge
of, any or all of the Collateral Documents, any termination of this Agreement
and the resignation or replacement of the Agent.

        For the purposes of this SECTION 13.7, "INDEMNIFIED LIABILITIES" shall
mean: any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, charges, expenses and disbursements (including
reasonable fees of attorneys for the Agent (including the allocable costs of
internal legal services and all disbursements of internal counsel)) of any kind
or nature whatsoever which may at any time (including at any time following
repayment of the Loans and the termination, resignation or replacement of the
Agent or the replacement of any Bank) be imposed on, incurred by or asserted
against any Agent-Related Person in any way relating to or arising out of this
Agreement or any document contemplated by or referred to herein, or the
transactions contemplated hereby, or 

                                       66
<PAGE>
any action taken or omitted by any such Person under or in connection with any
of the foregoing, including with respect to any investigation, litigation or
proceeding (including (a) any case, action or proceeding before any court or
other governmental authority relating to bankruptcy, reorganization, insolvency,
liquidation, receivership, dissolution, winding-up or relief of debtors, or (b)
any general assignment for the benefit of creditors, composition, marshalling of
assets for creditors, or other, similar arrangement in respect of its creditors
generally or any substantial portion of its creditors; undertaken under U.S.
Federal, state or foreign law, including the Bankruptcy Code, and including any
appellate proceeding) related to or arising out of this Agreement or the
Commitments or the use of the proceeds thereof, whether or not any Agent-Related
Person, any Bank or any of their respective officers, directors, employees,
counsel, agents or attorneys-in-fact is a party thereto.

        13.8 AGENT IN INDIVIDUAL CAPACITY. BofA and its Affiliates may make
loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with the Company and its
Subsidiaries and Affiliates as though BofA were not the Agent, the Issuing Bank
or the Swing Line Bank hereunder and without notice to or consent of the Banks.
The Banks acknowledge that, pursuant to such activities, BofA or its Affiliates
may receive information regarding the Company or its Affiliates (including
information that may be subject to confidentiality obligations in favor of the
Company or such Subsidiary) and acknowledge that the Agent shall be under no
obligation to provide such information to them. With respect to their Loans,
BofA and its Affiliates shall have the same rights and powers under this
Agreement as any other Bank and may exercise the same as though BofA were not
the Agent, the Issuing Bank and the Swing Line Bank, and the terms "Bank" and
"Banks" include BofA and its Affiliates, to the extent applicable, in their
individual capacities.

        13.9 SUCCESSOR AGENT. The Agent may, and at the request of the Required
Banks shall, resign as Agent upon 30 days' notice to the Banks. If the Agent
resigns under this Agreement, the Required Banks shall, with (so long as no
Event of Default exists) the consent of the Company (which shall not be
unreasonably withheld or delayed), appoint from among the Banks a successor
agent for the Banks. If no successor agent is appointed prior to the effective
date of the resignation of the Agent, the Agent may appoint, after consulting
with the Banks and the Company, a successor agent from among the Banks. Upon the
acceptance of its appointment as successor agent hereunder, such successor agent
shall succeed to all the rights, powers and duties of the retiring Agent and the
term "Agent" shall mean such 

                                       67
<PAGE>
successor agent, and the retiring Agent's appointment, powers and duties as
Agent shall be terminated. After any retiring Agent's resignation hereunder as
Agent, the provisions of this SECTION 13 and SECTIONS 14.6 and 14.13 shall inure
to its benefit as to any actions taken or omitted to be taken by it while it was
Agent under this Agreement. If no successor agent has accepted appointment as
Agent by the date which is 30 days following a retiring Agent's notice of
resignation, the retiring Agent's resignation shall nevertheless thereupon
become effective and the Banks shall perform all of the duties of the Agent
hereunder until such time, if any, as the Required Banks appoint a successor
agent as provided for above. Notwithstanding the foregoing, however, BofA may
not be removed as the Agent at the request of the Required Banks unless BofA
shall also simultaneously be replaced as an "Issuing Bank" and the "Swing Line
Bank" hereunder pursuant to documentation in form and substance reasonably
satisfactory to BofA.

        13.10  WITHHOLDING TAX.

               (a) If any Bank is a "foreign corporation, partnership or trust"
        within the meaning of the Code and such Bank claims exemption from, or a
        reduction of, U.S. withholding tax under Sections 1441 or 1442 of the
        Code, such Bank agrees to deliver to the Agent:

                      (i) if such Bank claims an exemption from, or a reduction
               of, withholding tax under a United States tax treaty, properly
               completed Internal Revenue Service ("IRS") Forms 1001 and W-8
               before the payment of any interest in the first calendar year and
               before the payment of any interest in each third succeeding
               calendar year during which interest may be paid under this
               Agreement;

                      (ii) if such Bank claims that interest paid under this
               Agreement is exempt from United States withholding tax because it
               is effectively connected with a United States trade or business
               of such Bank, two properly completed and executed copies of IRS
               Form 4224 before the payment of any interest is due in the first
               taxable year of such Bank and in each succeeding taxable year of
               such Bank during which interest may be paid under this Agreement,
               and IRS Form W-9; and

                      (iii) such other form or forms as may be required under
                the Code or other laws of the United States as a condition to
                exemption 

                                       68
<PAGE>
                from, or reduction of, United States withholding tax. 

                Such Bank agrees to promptly notify the Agent of any change in
                circumstances which would modify or render invalid any claimed
                exemption or reduction.

               (b) If any Bank claims exemption from, or reduction of,
        withholding tax under a United States tax treaty by providing IRS Form
        1001 and such Bank sells, assigns, grants a participation in, or
        otherwise transfers all or part of the obligations of the Company to
        such Bank, such Bank agrees to notify the Agent of the percentage amount
        in which it is no longer the beneficial owner of such obligations of the
        Company hereunder. To the extent of such percentage amount, the Agent
        will treat such Bank's IRS Form 1001 as no longer valid.

               (c) If any Bank claiming exemption from United States withholding
        tax by filing IRS Form 4224 with the Agent sells, assigns, grants a
        participation in, or otherwise transfers all or part of the obligations
        of the Company to such Bank hereunder, such Bank agrees to undertake
        sole responsibility for complying with the withholding tax requirements
        imposed by Sections 1441 and 1442 of the Code.

               (d) If any Bank is entitled to a reduction in the applicable
        withholding tax, the Agent may withhold from any interest payment to
        such Bank an amount equivalent to the applicable withholding tax after
        taking into account such reduction. If the forms or other documentation
        required by SUBSECTION (A) of this Section are not delivered to the
        Agent, then the Agent may withhold from any interest payment to such
        Bank not providing such forms or other documentation an amount
        equivalent to the applicable withholding tax.

               (e) If the IRS or any other governmental authority of the United
        States or any other jurisdiction asserts a claim that the Agent did not
        properly withhold tax from amounts paid to or for the account of any
        Bank (because the appropriate form was not delivered or was not properly
        executed, or because such Bank failed to notify the Agent of a change in
        circumstances which rendered the exemption from, or reduction of,
        withholding tax ineffective, or for any other reason) such Bank shall
        indemnify the Agent fully for all amounts paid, directly or indirectly,
        by the Agent as tax or otherwise, including penalties and 

                                       69
<PAGE>
        interest, and including any taxes imposed by any jurisdiction on the
        amounts payable to the Agent under this Section, together with all costs
        and expenses (including reasonable fees of attorneys for the Agent
        (including the allocable costs of internal legal services and all
        disbursements of internal counsel)). The obligation of the Banks under
        this subsection shall survive the repayment of the Loans, cancellation
        of the Notes, any termination of this Agreement and the resignation or
        replacement of the Agent.

        13.11 COLLATERAL MATTERS. The Banks irrevocably authorize the Agent, at
its option and in its discretion, to release any Lien granted to or held by the
Agent under any Collateral Document (i) upon termination of the Commitments and
payment in full of all Loans and all other obligations of the Company hereunder
and the expiration or termination of all Letters of Credit; (ii) constituting
property sold or to be sold or disposed of as part of or in connection with any
disposition permitted hereunder; or (iii) subject to SECTION 14.1, if approved,
authorized or ratified in writing by the Required Banks. Upon request by the
Agent at any time, the Banks will confirm in writing the Agent's authority to
release particular types or items of collateral pursuant to this SECTION 13.11.

        13.12 CO-AGENTS. No Bank identified on the facing page or the signature
pages of this Agreement as a "Co-Agent" shall have any right, power, obligation,
liability, responsibility or duty under this Agreement other than those
applicable to all Banks as such. Without limiting the foregoing, no Bank so
identified as a "Co-Agent" shall have or be deemed to have any fiduciary
relationship with any Bank. Each Bank acknowledges that it has not relied, and
will not rely, on any Bank so identified in deciding to enter into this
Agreement or in taking or not taking action hereunder.

        SECTION 14  GENERAL.

        14.1 WAIVER; AMENDMENTS. No delay on the part of the Agent, any Bank or
any other holder of a Note in the exercise of any right, power or remedy shall
operate as a waiver thereof, nor shall any single or partial exercise by any of
them of any right, power or remedy preclude other or further exercise thereof,
or the exercise of any other right, power or remedy. No amendment, modification
or waiver of, or consent with respect to, any provision of this Agreement or the
Notes shall in any event be effective unless the same shall be in writing and
signed and delivered by Banks having an aggregate Percentage of not less than
the aggregate Percentage expressly designated herein with respect thereto or, in
the absence of such designation as to any provision of this Agreement or the
Notes, by the Required Banks, 

                                       70
<PAGE>
and then any such amendment, modification, waiver or consent shall be effective
only in the specific instance and for the specific purpose for which given. No
amendment, modification, waiver or consent shall change the Percentage of any
Bank without the consent of such Bank. No amendment, modification, waiver or
consent shall (i) extend or increase the amount of the Commitments, (ii) extend
the date for payment of any principal of or interest on the Loans or any fees
payable hereunder, (iii) reduce the principal amount of any Loan, the rate of
interest thereon or any fees payable hereunder, (iv) release the Guaranty (other
than with respect to a Guarantor which ceases to be a Subsidiary as a result of
a transaction permitted hereunder) or all or substantially all of the collateral
granted under the Collateral Document or (v) reduce the aggregate Percentage
required to effect an amendment, modification, waiver or consent without, in
each case, the consent of all Banks. No provisions of SECTION 13 or other
provision of this Agreement affecting the Agent in its capacity as such shall be
amended, modified or waived without the consent of the Agent. No provision of
this Agreement relating to the rights or duties of an Issuing Bank in its
capacity as such shall be amended, modified or waived without the consent of
such Issuing Bank. No provision of this Agreement affecting the Swing Line Bank
in its capacity as such shall be amended, modified or waived without the written
consent of the Swing Line Bank.

        14.2 CONFIRMATIONS. The Company and each holder of a Note agree from
time to time, upon written request received by it from the other, to confirm to
the other in writing (with a copy of each such confirmation to the Agent) the
aggregate unpaid principal amount of the Loans then outstanding under such Note.

        14.3 NOTICES. Except as otherwise provided in SECTIONS 2.2, 2.4 and 4.3,
all notices hereunder shall be in writing (including facsimile transmission) and
shall be sent to the applicable party at its address shown on SCHEDULE 14.3 or
at such other address as such party may, by written notice received by the other
parties, have designated as its address for such purpose. Notices sent by
facsimile transmission shall be deemed to have been given when sent; notices
sent by mail shall be deemed to have been given three Business Days after the
date when sent by registered or certified mail, postage prepaid; and notices
sent by hand delivery or overnight courier service shall be deemed to have been
given when received. For purposes of SECTIONS 2.2, 2.4 and 4.3, the Agent and
the Swing Line Bank shall be entitled to rely on telephonic instructions from
any person that the Agent or the Swing Line Bank in good faith believes is an
authorized officer or employee of the Company, and the Company shall hold the
Agent, the Swing Line Bank and each other Bank harmless from any loss, cost or
expense resulting from any such reliance.

                                       71

        14.4  COMPUTATIONS.  Where the character or amount of any asset or 
liability or item of income or expense is required to be determined, or any
consolidation or other accounting computation is required to be made, for the
purpose of this Agreement, such determination or calculation shall, to the
extent applicable and except as otherwise specified in this Agreement, be made
in accordance with GAAP, consistently applied; PROVIDED that if the Company
notifies the Agent that the Company wishes to amend any covenant in SECTION 10
to eliminate or to take into account the effect of any change in GAAP on the
operation of such covenant (or if the Agent notifies the Company that the
Required Banks wish to amend SECTION 10 for such purpose), then the Company's
compliance with such covenant shall be determined on the basis of GAAP in effect
immediately before the relevant change in GAAP became effective, until either
such notice is withdrawn or such covenant is amended in a manner satisfactory to
the Company and the Required Banks.

        14.5 REGULATION U. Each Bank represents that it in good faith is not
relying, either directly or indirectly, upon any Margin Stock as collateral
security for the extension or maintenance by it of any credit provided for in
this Agreement.

        14.6 COSTS, EXPENSES AND TAXES. The Company agrees to pay on demand all
reasonable out-of-pocket costs and expenses of the Agent (including the
reasonable fees and charges of counsel for the Agent and of local counsel, if
any, who may be retained by said counsel) in connection with the preparation,
execution, delivery and administration of this Agreement, the other Loan
Documents and all other documents provided for herein or delivered or to be
delivered hereunder or in connection herewith (including any amendments,
supplements or waivers to any Loan Documents), and all reasonable out-of-pocket
costs and expenses (including reasonable attorneys' fees, court costs and other
legal expenses and allocated costs of staff counsel) incurred by the Agent and
each Bank after an Event of Default in connection with the enforcement of this
Agreement, the other Loan Documents or any such other documents. Each Bank
agrees to reimburse the Agent for such Bank's pro rata share (based on its
respective Percentage) of any such costs and expenses of the Agent not paid by
the Company. In addition, the Company agrees to pay, and to save the Agent and
the Banks harmless from all liability for, (a) any stamp or other taxes
(excluding income taxes and franchise taxes based on net income) which may be
payable in connection with the execution and delivery of this Agreement, the
borrowings hereunder, the issuance of the Notes or the execution and delivery of
any other Loan Document or any other document provided for herein or delivered
or to be delivered hereunder or in connection herewith and (b) any fees of the
Company's auditors in connection with any reasonable exercise by the Agent and
the 

                                       72
<PAGE>
Banks of their rights pursuant to SECTION 10.2. All obligations provided for
in this SECTION 14.6 shall survive repayment of the Loans, cancellation of the
Notes and any termination of this Agreement.

        14.7 SUBSIDIARY REFERENCES. The provisions of this Agreement relating to
Subsidiaries shall apply only during such times as the Company has one or more
Subsidiaries.

        14.8 CAPTIONS. Section captions used in this Agreement are for
convenience only and shall not affect the construction of this Agreement.

        14.9  ASSIGNMENTS; PARTICIPATIONS.

        14.9.1 ASSIGNMENTS. Any Bank may, with the prior written consents of the
Company and the Agent (which consents shall not be unreasonably delayed or
withheld), at any time assign and delegate to one or more commercial banks or
other Persons (any Person to whom such an assignment and delegation is to be
made being herein called an "ASSIGNEE"), all or any fraction of such Bank's
Revolving Loans and Commitment (which assignment and delegation shall be of a
constant, and not a varying, percentage of all the assigning Bank's Revolving
Loans and Commitment) in a minimum aggregate amount equal to the lesser of (i)
the amount of the assigning Bank's remaining Commitment and (ii) $5,000,000;
PROVIDED, HOWEVER, that (a) no assignment and delegation may be made to any
Person if, at the time of such assignment and delegation, the Company would be
obligated to pay any greater amount under SECTION 7.6 or SECTION 8 to the
Assignee than the Company is then obligated to pay to the assigning Bank under
such Sections (and if any assignment is made in violation of the foregoing, the
Company will not be required to pay the incremental amounts) and (b) the Company
and the Agent shall be entitled to continue to deal solely and directly with
such Bank in connection with the interests so assigned and delegated to an
Assignee until the date when all of the following conditions shall have been
met:

               (x) five Business Days (or such lesser period of time as the
        Agent and the assigning Bank shall agree) shall have passed after
        written notice of such assignment and delegation, together with payment
        instructions, addresses and related information with respect to such
        Assignee, shall have been given to the Company and the Agent by such
        assigning Bank and the Assignee,

               (y) the assigning Bank and the Assignee shall have executed and
        delivered to the Company and the Agent an assignment agreement
        substantially in the form of EXHIBIT G (an "ASSIGNMENT AGREEMENT"),
        together with any documents required to be delivered thereunder, which
        Assignment 


                                       73
<PAGE>
        Agreement shall have been accepted by the Agent, and

               (z) the assigning Bank or the Assignee shall have paid the Agent
        a processing fee of $3,500.

From and after the date on which the conditions described above have been met,
(x) such Assignee shall be deemed automatically to have become a party hereto
and, to the extent that rights and obligations hereunder have been assigned and
delegated to such Assignee pursuant to such Assignment Agreement, shall have the
rights and obligations of a Bank hereunder, and (y) the assigning Bank, to the
extent that rights and obligations hereunder have been assigned and delegated by
it pursuant to such Assignment Agreement, shall be released from its obligations
hereunder. Within five Business Days after effectiveness of any assignment and
delegation, the Company shall execute and deliver to the Agent (for delivery to
the Assignee and the Assignor, as applicable) a new Note in the principal amount
of the Assignee's Percentage of the Commitment Amount and, if the assigning Bank
has retained a Commitment hereunder, a replacement Note in the principal amount
of the Percentage of the Commitment Amount retained by the assigning Bank (such
Note to be in exchange for, but not in payment of, the predecessor Note held by
such assigning Bank). Each such Note shall be dated the effective date of such
assignment. The assigning Bank shall mark the predecessor Note "exchanged" and
deliver it to the Company. Accrued interest on that part of the predecessor Note
being assigned shall be paid as provided in the Assignment Agreement. Accrued
interest and fees on that part of the predecessor Note not being assigned shall
be paid to the assigning Bank. Accrued interest and accrued fees shall be paid
at the same time or times provided in the predecessor Note and in this
Agreement. Any attempted assignment and delegation not made in accordance with
this SECTION 14.9.1 shall be null and void.

        Notwithstanding the foregoing provisions of this SECTION 14.9.1 or any
other provision of this Agreement, any Bank may at any time assign all or any
portion of its Loans and its Note to a Federal Reserve Bank (but no such
assignment shall release any Bank from any of its obligations hereunder).

        14.9.2 PARTICIPATIONS. Any Bank may at any time sell to one or more
commercial banks or other Persons participating interests in any Loan owing to
such Bank, the Note held by such Bank, the Commitment of such Bank, the direct
or participation interest of such Bank in any Letter of Credit or any other
interest of such Bank hereunder (any Person purchasing any such participating
interest being herein called a "PARTICIPANT"); PROVIDED that any Bank selling
any such participating interest shall give notice thereof to the Company. In the
event of a sale by a Bank of a participating interest to a Participant, (x) such

                                       74
<PAGE>
Bank shall remain the holder of its Note for all purposes of this Agreement, (y)
the Company and the Agent shall continue to deal solely and directly with such
Bank in connection with such Bank's rights and obligations hereunder and (z) all
amounts payable by the Company shall be determined as if such Bank had not sold
such participation and shall be paid directly to such Bank. No Participant shall
have any direct or indirect voting rights hereunder except with respect to any
of the events (excluding the events described in CLAUSE (V) thereof) described
in the fourth sentence of SECTION 14.1. Each Bank agrees to incorporate the
requirements of the preceding sentence into each participation agreement which
such Bank enters into with any Participant. The Company agrees that if amounts
outstanding under this Agreement and the Notes are due and payable (as a result
of acceleration or otherwise), each Participant shall be deemed to have the
right of setoff in respect of its participating interest in amounts owing under
this Agreement, any Note and with respect to any Letter of Credit to the same
extent as if the amount of its participating interest were owing directly to it
as a Bank under this Agreement or such Note; PROVIDED that such right of setoff
shall be subject to the obligation of each Participant to share with the Banks,
and the Banks agree to share with each Participant, as provided in SECTION 7.5.
The Company also agrees that each Participant shall be entitled to the benefits
of SECTION 7.6 and SECTION 8 as if it were a Bank (provided that no Participant
shall receive any greater compensation pursuant to SECTION 7.6 or SECTION 8 than
would have been paid to the participating Bank if no participation had been
sold).

        14.10 GOVERNING LAW. This Agreement and each Note shall be a contract
made under and governed by the internal laws of the State of Illinois. Whenever
possible each provision of this Agreement shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision of this
Agreement shall be prohibited by or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
Agreement. All obligations of the Company and rights of the Agent, the Banks and
any other holder of a Note expressed herein or in any other Loan Document shall
be in addition to and not in limitation of those provided by applicable law.

        14.11 COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts and
each such counterpart shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same Agreement.

        14.12 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
Company, the Banks and the Agent and their 

                                       75
<PAGE>
respective successors and assigns, and shall inure to the benefit of the
Company, the Banks and the Agent and the successors and assigns of the Banks and
the Agent.

        14.13  INDEMNIFICATION BY THE COMPANY.

        (a) In consideration of the execution and delivery of this Agreement by
the Agent and the Banks and the agreement to extend the Commitments provided
hereunder, the Company hereby agrees to indemnify, exonerate and hold the Agent,
each Bank and each of the officers, directors, employees, Affiliates and agents
of the Agent and each Bank (each a "BANK PARTY") free and harmless from and
against any and all actions, causes of action, suits, losses, liabilities,
damages and expenses, including reasonable attorneys' fees and charges and
allocated costs of staff counsel (collectively, for purposes of this SECTION
14.13, called the "INDEMNIFIED LIABILITIES"), incurred by the Bank Parties or
any of them as a result of, or arising out of, or relating to (i) any tender
offer, merger, purchase of stock, purchase of assets or other similar
transaction financed or proposed to be financed in whole or in part, directly or
indirectly, with the proceeds of any of the Loans, (ii) the use, handling,
release, emission, discharge, transportation, storage, treatment or disposal of
any hazardous substance at any property owned or leased by the Company or any
Subsidiary, (iii) any violation of any Environmental Laws with respect to
conditions at any property owned or leased by the Company or any Subsidiary or
the operations conducted thereon, (iv) the investigation, cleanup or remediation
of offsite locations at which the Company or any Subsidiary or their respective
predecessors are alleged to have directly or indirectly disposed of hazardous
substances or (v) the execution, delivery, performance or enforcement of this
Agreement or any other Loan Document by any of the Bank Parties, except for any
such Indemnified Liabilities arising on account of any such Bank Party's gross
negligence or willful misconduct. If and to the extent that the foregoing
undertaking may be unenforceable for any reason, the Company hereby agrees to
make the maximum contribution to the payment and satisfaction of each of the
Indemnified Liabilities which is permissible under applicable law. Nothing set
forth above shall be construed to relieve any Bank Party from any obligation it
may have under this Agreement.

        (b) All obligations provided for in this SECTION 14.13 shall survive
repayment of the Loans, cancellation of the Notes, any foreclosure under, or any
modification, release or discharge of any or all of the Collateral Documents and
any termination of this Agreement.

EXTENT THAT THE COMPANY HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM
JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR
NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR
OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, THE COMPANY HEREBY
IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS

FROM ANY BANKING RELATIONSHIP EXISTING IN CONNECTION WITH ANY OF THE FOREGOING,
AND AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND

U S Liquids Inc.

Gentlemen:

      We have acted as counsel for U S Liquids Inc., a Delaware corporation (the
"Company"), in connection with the registration by the Company under the
Securities Act of 1933, as amended (the "Securities Act"), of the sale of up to
4,312,500 shares of Common Stock, par value $.01 per share (the "Shares"), of
the Company pursuant to a Registration Statement on Form S-1 (as amended or
supplemented, the "Registration Statement") filed with the Securities and
Exchange Commission (the "Commission") on May 7, 1998. All terms used and not
defined herein shall have the meanings set forth in the Registration Statement.

      We have examined such documents, records and matters of law as we have
deemed necessary for the purposes of this opinion, and based thereon, we are of
the opinion that the Shares to be issued and sold by the Company have been duly
and validly authorized for issuance and, upon issuance pursuant to the terms of
the Underwriting Agreement, will be validly issued, fully paid and
nonassessable.

      The foregoing opinion is based on and is limited to the laws of the
General Corporation Law of the State of Delaware, and we render no opinion with
respect to any other law.

      We hereby consent to the filing of the foregoing opinion as an exhibit to
the Registration Statement and the reference to our firm under the caption
"Legal Matters" in the Prospectus constituting a part of the Registration
Statement.

                                          Sincerely,

                             HARTZOG CONGER & CASON

the extent that the assignment hereunder of any Customer Account or Assumed
Lease shall require the consent of any third party, neither this Agreement nor
any action taken pursuant to its provisions shall constitute an assignment or an
agreement to assign if such assignment or attempted assignment would constitute
a breach thereof or result in the loss or diminution thereof; provided, however,
that in each such case, Seller shall use its reasonable efforts to obtain the
consent of such other party to such assignment to Buyer. If such consent is not
obtained, Seller shall cooperate with Buyer in any reasonable arrangement
designed to provide for Buyer the benefits under any such Customer Account or
Assumed Lease, including, without limitation, an adjustment of the purchase
price set forth in Section 2.1 hereof and enforcement for the account and
benefit of Buyer, of any and all rights of Seller against any other person
arising out of the breach or cancellation of any such Customer Account or
Assumed Lease by such other person, or otherwise. Attached hereto as Schedule
1.3 is a list of all Customer Accounts or Assumed Leases requiring consent to
their assignment.

               SECTION 1.4 SELLER ACCOUNTS RECEIVABLE. (a) Buyer shall have no
        liability or obligation whatsoever to Seller in connection with the
        Accounts Receivable and Buyer shall not be responsible for collecting
        the Accounts Receivable. However, if Buyer receives any payments which
        are designated by the customer as being toward such Accounts Receivable,
        then Buyer shall forward such payments to Seller as set forth in Section
        1.4(b). Attached hereto as Schedule 1.4 is a true and complete list of
        all Accounts Receivable of Seller as of the close of business on
        December 31, 1997.

<PAGE>
               (b) All sums representing Accounts Receivable as set forth on
        Schedule 1.4 collected by Buyer from the customers set forth on Schedule
        1.1(d) shall be conclusively presumed to be receipts from the collection
        of the oldest Accounts Receivable of such customer unless the customer
        specifically indicates otherwise in writing. All such sums received by
        Buyer shall be received in trust and shall be remitted to Seller on a
        weekly basis, together with an itemized list of the sources thereof.
        Seller shall be entitled to take such action as may be necessary in
        order to collect its unpaid Accounts Receivable; provided, however, that

               ARTICLE 5. REPRESENTATIONS AND WARRANTIES OF SELLER
                                AND STOCKHOLDERS

               SECTION 5.1 Seller and each Stockholder, severally (and not
jointly and severally), represent and warrant to Buyer that:

               (a)    AUTHORITY.

                      (i) Seller is a corporation duly formed, validly existing
               and in good standing under the laws of the State of Texas. The
               execution and delivery of this Agreement, the consummation of the
               transactions contemplated hereby and the compliance by Seller and
               Stockholders with the terms of this Agreement do not and will not
               conflict with or result in a breach of any terms of, or
               constitute a default under, the articles of incorporation or
               bylaws of Seller, or any instrument or other agreement to which
               Seller or any Stockholder is a party or by which Seller or any
               Stockholder is bound. This Agreement constitutes a valid
               obligation of Seller and Stockholders enforceable against Seller
               and each Stockholder in accordance with its terms except as
               limited by bankruptcy, insolvency, reorganization or other such
               laws concerning the rights of creditors.

                      (ii) Each Stockholder is competent, under no duress or
               legal restraint, and has all necessary authority to enter into
               this Agreement, perform his obligations hereunder and consummate
               the transactions contemplated hereby.

                                       -6-
<PAGE>
                      (iii) All of the issued and outstanding shares of Seller
               are owned of record and beneficially by Stockholders, free and
               clear of all liens, security interests and encumbrances
               whatsoever.

               (b) COMPLIANCE WITH LAW. To the best of Stockholders' and
        Seller's knowledge, except as set forth on Schedule 5.1(b), neither
        Seller nor any Stockholder is in default under any applicable federal,
        state or local laws, statutes, ordinances, permits, licenses, orders,
        approvals, variances, rules or regulations or judicial or administrative
        decisions ("Applicable Laws") which would have an adverse effect upon
        the Assets or the Business and Seller has been granted all licenses,
        permits, consents, authorizations and approvals from federal, state and
        local government regulatory bodies necessary or desirable to carry on
        the Business, all of which are currently in full force and effect. Each
        of the Assets complies in all respects with all federal, state and local
        laws, statutes, ordinances, permits, licenses, approvals, rules and
        regulations applicable thereto.

               (c) EQUIPMENT. Listed on Schedule 1.1(a) hereto is a complete and
        accurate list of all Equipment used or for use in connection with the
        Business. Each piece of Equipment is in operating condition on the date
        hereof.

               (d) ROLLING STOCK. Listed on Schedule 1.1(b) hereto is a complete
        and accurate list of all Rolling Stock. Each motor vehicle, attachment,
        accessory and piece of materials handling equipment comprising the
        Rolling Stock is in operating condition on the date hereof.

               (e) CUSTOMER ACCOUNTS. Listed on Schedule 1.1(d) hereto is a
        complete and accurate list of the Customer Accounts as of the date
        hereof. Except as set forth on Schedule 1.3, all Customer Accounts are
        (and will be immediately following the Closing) in full force and effect
        and are valid, binding and enforceable against the respective parties
        thereto in accordance with their respective provisions, and Seller is
        not in default in, nor has there occurred an event or condition
        (including Seller's execution and delivery of or performance under this
        Agreement) which with the passage of time or the giving of notice (or
        both) would constitute a default, with regard to the payment or
        performance of any obligation under any Customer Account; no claim of
        such a default has been asserted and there is no reasonable basis upon
        which such a claim could validly be made. Neither Seller nor any
        Stockholder has received any notice that any person intends or desires
        to modify, waive, amend, rescind, release, cancel or terminate any
        written Customer Account. By virtue of the grant, conveyance, sale,
        transfer and assignment of the written Customer Accounts by Seller to
        Buyer hereunder, Buyer shall own and hold all right, title and interest
        of Seller in and to the Customer Accounts, without the consent or
        approval of any other person or entity.

               (f) TITLE TO THE ASSETS. Seller has good and marketable title to
        the Assets, free and clear of all liens, encumbrances, security
        interests, equities or restrictions whatsoever, except the Assumed
        Leases, and, by virtue of the grant, conveyance, sale, transfer, and
        assignment of the Assets hereunder, Buyer shall receive good and
        marketable title to the

                                       -7-
<PAGE>
        Assets, free and clear of all liens, lease payments (including lease-end
        buy-out payments), encumbrances, security interests, equities or
        restrictions whatsoever, except the Assumed Leases. The Assets include
        all of the permits, licenses, franchises, consents and other approvals
        necessary or desirable to conduct the Business.

               (g) TITLE TO REAL PROPERTY. Seller has never owned, leased or
        otherwise occupied, had an interest in or operated any real property
        other than the Land. Seller has good, valid leasehold title to the Land.
        Except as set forth on Schedule 5.1(g):

                      (i) The Land is, and at all times during operation of the
               Business has been, fully licensed, permitted and authorized for
               the operation of the Business under all Applicable Laws relating
               to the protection of the environment, the Land and the conduct of
               the Business thereon (including, without limitation, all zoning
               restrictions and land use requirements).

                      (ii) The Land is usable for its current uses and to the
               best of Stockholders' and Seller's knowledge, can be used by
               Buyer after the Closing for such uses without violating any
               applicable law or private restriction, and such uses are legal
               conforming uses. There are no proceedings or amendments pending
               and brought by or, to the best of Seller's knowledge, threatened
               by, any third party which would result in a change in the
               allowable uses of the Land or which would modify the right of
               Buyer to use the Land for its current uses after the Closing
               Date.

                      (iii) Stockholders and Company have made available to
               Buyer all engineering, geologic and other similar reports,
               documentation and maps relating to the Land in the possession or
               control of Seller.

                      (iv) Neither Seller, Stockholders nor the Land now is or
               ever has been involved in any litigation or administrative
               proceeding seeking to impose fines, penalties or other
               liabilities or seeking injunctive relief for violation of any
               Applicable Laws relating to the environment.

                      (v) No third party has a present or future right to
               possession of all or any part of the Land except the landlord
               under the Real Estate Lease.

               (h) LITIGATION. Except as set forth on Schedule 5.1(h) hereof,
        there is no claim, litigation, action, suit or proceeding,
        administrative or judicial, pending or, to the best of Stockholders' and
        Seller's knowledge, threatened against Seller or Stockholder, or
        involving the Assets or the Business, at law or in equity, before any
        federal, state or local court or regulatory agency, or other
        governmental authority. Neither Seller nor any Stockholder has received
        any notice of any of the above and no facts or circumstances exist which
        would, with the passage of time or giving of notice (or both), give rise
        to any of the above.

                                       -8-
<PAGE>
               (i) EMPLOYEES. Attached as Schedule 5.1(i) hereof is a complete
        list of all employees of Seller and their respective rates of
        compensation (including a breakdown of the portion thereof attributable
        to salary, bonus and other compensation, respectively) as of the date of
        Closing. Each employee is an employee at will and there are no
        collective bargaining agreements affecting any employee of Seller. Buyer
        shall not be obligated to hire any of Seller's employees.

               (j) EMPLOYEE RELATIONS AND BENEFIT PLANS. Set forth on Schedule
        5.1(j) is an accurate and complete list of all agreements of any kind
        between Seller and its employees or group of employees, including,
        without limitation, employment agreements, collective bargaining
        agreements and benefit plans. Buyer shall not, by the execution and
        delivery of this Agreement or otherwise, become obligated to or assume
        any liabilities or contractual obligations with respect to any employee
        of Seller or otherwise become liable for or obligated in any manner
        (contractual or otherwise) to any employee of Seller, including, without
        limiting the generality of the foregoing, any liability or obligation
        pursuant to any collective bargaining agreement, employment agreement,
        or pension, profit sharing or other employee benefit plan (within the
        meaning of Section 3(3) of the Employment Retirement Income Security Act
        of 1974, as amended) or any other fringe benefit program maintained by
        Seller or to which Seller contributes or any liability for the
        withdrawal or partial withdrawal from or termination of any such plan or
        program by Seller.

               (k) FINANCIAL STATEMENTS. Seller has delivered to Buyer copies of
        Seller's Statement of Assets, Liabilities and Equity-- Income Tax Basis
        as of December 31, 1996 (the "Balance Sheet Date"), and a Statement of
        Revenue and Expenses-- Income Tax Basis for the year then ended (the
        "Financial Statements"). The Financial Statements are true, complete and
        correct and present fairly the financial condition and the results of
        the operations of Seller for the period indicated thereon. All reserves
        for contingent risks are appropriate and sufficient to cover all costs
        reasonably expected to be incurred from such risks. The Financial
        Statements are consistent with the books and records of Seller (which
        books and records are correct and complete).

               (l) TAXES. No federal, state, local or other tax returns or
        reports filed by Seller (whether filed prior to, on or after the date
        hereof) with respect to the Business or the Assets will result in any
        taxes, assessments, fees or other governmental charges upon the Assets
        or Buyer, whether as a transferee of the Assets or otherwise. All
        federal, state and local taxes due and payable with respect to the
        Business or the Assets have been paid, including, without limiting the
        generality of the foregoing, all federal, state and local income, sales,
        use, franchise, excise and property taxes.

               (m) HAZARDOUS MATERIALS. Neither Seller nor Stockholders has ever
        generated, transported, stored, handled, recycled, reclaimed, disposed
        of, or contracted for the disposal of, hazardous materials, hazardous
        wastes, hazardous substances, toxic wastes or substances, infectious or
        medical waste, radioactive waste or sewage sludges as those terms are
        defined by the Resource Conservation and Recovery Act of 1976; the

                                       -9-
<PAGE>
        Comprehensive Environmental Response, Compensation and Liability Act of
        1980 ("CERCLA"); the Atomic Energy Act of 1954; the Toxic Substances
        Control Act; the Occupational Health and Safety Act; any comparable or
        similar Texas statute; or the rules and regulations promulgated under
        any of the foregoing, as each of the foregoing may have been from time
        to time amended (collectively, "Hazardous Materials"). Seller has never
        owned, operated, had an interest in, engaged in and/or leased a waste
        transfer, recycling, treatment, storage or disposal facility, business
        or activity other than the Business. To the best of Stockholders' and
        Sellers's knowledge, Seller has obtained and maintained all necessary
        trip tickets, signed by the applicable waste generators, and other
        records demonstrating the nature of the waste transported in connection
        with the Business. To the best of Stockholders' and Seller's knowledge,
        no employee, contractor or agent of Seller has, in the course and scope
        of employment with Seller, been harmed by exposure to Hazardous
        Materials. To the best of Stockholders' and Seller's knowledge, Seller
        has no direct or contingent liability or obligation for or in connection
        with any claimed release, discharge or leak of any substance onto the
        Land or into the environment. Further, no portion of the Land is listed
        on the CERCLA list or the National Priorities List of Hazardous Waste
        Sites or any similar list maintained by the State of Texas. Attached
        hereto as Schedule 5.1(m) is a complete list of the names and addresses
        of all disposal sites at any time now or in the past utilized by Seller,
        none of which sites is listed on the CERCLA list or the National
        Priorities List of Hazardous Waste Sites or any comparable Texas list.
        Neither Seller, Stockholders nor the Land is listed as a potentially
        responsible party under CERCLA or any comparable or similar Texas
        statute; neither Seller nor Stockholders has received any written notice
        of such a listing; and neither Seller nor Stockholders knows of any
        facts or circumstances which could give rise to such a listing.

               (n) GOVERNMENT NOTICES. Seller has delivered to Buyer, a
        description and copies, as of the date of this Agreement, of all
        notifications, filed or submitted, or required to be filed or submitted,
        to governmental agencies and of all material notifications from such
        governmental agencies relating to Seller and the Assets or relating to
        the discharge or release of materials into the environment or otherwise
        relating to the protection of the public health or the environment.

               (o) ABSENCE OF PRICE RENEGOTIATION CONTRACTS. Seller is not now
        nor has ever been a party to any governmental contracts subject to price
        redetermination or renegotiation.

               (p) GROSS REVENUES. The gross revenues generated by the Business
        for the 12- month period immediately preceding the month in which the
        Closing occurs were $657,675.88.

               (q) UNDERGROUND STORAGE TANKS. Except for the Land, Seller has
        never owned, leased or operated any real estate having any underground
        storage tanks containing petroleum products or wastes or other hazardous
        substances regulated by 40 CFR 280 and/or other applicable federal,
        state or local laws, rules and regulations and requirements.

                                            -10-
<PAGE>
        Set forth on Schedule 5.1(q) is a list of all above and below ground
        tanks located on the Land, each of which are being used and maintained
        in accordance with Applicable Laws.

               (r) COMPLETENESS OF DISCLOSURE. To the best of Stockholders' and
        Seller's knowledge, this Agreement and the Schedules hereto and all
        other documents and information furnished to Buyer and its
        representatives pursuant hereto do not and will not include any untrue
        statement of a material fact or omit to state a material fact necessary
        to make the statements therein not misleading. If Seller or Stockholders
        become aware of any fact or circumstance which would change a
        representation or warranty of Seller or Stockholders in this Agreement,
        the party with such knowledge shall immediately give notice of such fact
        or circumstance to Buyer. However, such notification shall not relieve
        Seller or Stockholders of their obligations under this Agreement, and at
        the sole option of Buyer, the truth and accuracy of any and all
        warranties and representations of Seller and Stockholders at the date of
        this Agreement shall be a precondition to the consummation of this
        transaction, provided that no party shall be entitled to rely on any
        representation or warranty provided in this Agreement to the extent such
        party has actual knowledge that such representation or warranty is
        inaccurate or incorrect.

               SECTION 5.2 SURVIVAL. Each of the representations and warranties
set forth in this Article 5 shall survive the Closing hereunder for a period of
one year after the Closing Date; provided, however, that the representations and
warranties in Sections 5.1(a) and 5.1(b) shall survive until the expiration of
the applicable status of limitations; and that the representations and
warranties in Sections 5.1(g) and 5.1(m) shall survive for a period of a three
years after the Closing Date.


                ARTICLE 6.  REPRESENTATIONS AND WARRANTIES OF BUYER AND PARENT

               SECTION 6.1  Buyer and Parent represent and warrant to Seller and

        Agreement, the consummation of the transactions contemplated hereby and
        the compliance by Buyer and Parent with the terms of this Agreement do
        not and will not conflict with or result in a breach of any terms of, or

amount whatsoever (including, without limitation, reasonable attorneys' fees),
whether equitable or legal, matured or contingent, known or unknown, foreseen or
unforeseen, ordinary or extraordinary, patent or latent, which result, either

               (i) liability of Seller or any Stockholder to creditors of Seller
        or any Stockholder which is imposed on Buyer whether as a result of
        bankruptcy proceedings or otherwise and whether as an account payable by

        or preferential payments within the meaning of the United States
        Bankruptcy Code or otherwise; and

                                            -13-

        satisfied.

Buyer shall be deemed to have suffered such loss, claim, action, cause of
action, damage, liability, expense or other cost, or to have paid or to have
become obligated to pay any sum on account, of, the matters referred to in
subparagraphs (a) - (l) of this Section 7.3 if the same shall be suffered, paid
or incurred by Buyer or any parent, subsidiary, affiliate, or successor of

liability, expense or other cost deemed to be suffered, paid or incurred by
Buyer shall be an amount equal to the loss, claim, action, cause of action,
damage, liability, expense or other cost suffered, paid or incurred by such
parent, subsidiary, affiliate, or successor.

               SECTION 7.4 INDEMNIFICATION BY BUYER AND PARENT. Buyer and

        Parent in this Agreement;

               (b) breach of any representation or warranty under this Agreement

               (e) any claim by a third party that, if true, would mean that a

        satisfied.

Seller shall be deemed to have suffered such loss, claim, action, cause of
action, damage, liability, expense or other cost, or to have paid or to have
become obligated to pay any sum on account, of, the matters referred to in
subparagraphs (a) - (d) of this Section 7.4 if the same shall be suffered, paid
or incurred by Seller or any subsidiary, affiliate, or successor of Seller. The
amount of the loss, claim, action, cause of action, damage, liability, expense
or other cost deemed to be suffered, paid or incurred by Seller shall be an
amount equal to the loss, claim, action,

                                      -14-
<PAGE>
cause of action, damage, liability, expense or other cost suffered, paid or
incurred by such subsidiary, affiliate, or successor.

               SECTION 7.5 LIMITATION ON LIABILITY. The indemnification
obligations set forth in this Agreement shall apply only after the aggregate
amount of such obligations exceed $50,000, when combined with the Agreement and

Liquids Inc., Buyer and Stockholders (the "Merger Agreement"), and the Stock
Purchase Agreement among Buyer, U S Liquids Inc., Enviro Waste Type V of Texas,
Inc. and Stockholders (the "Stock Purchase Agreement"), at which time the
indemnification obligations shall be effective as to all amounts, including the
initial $50,000 and shall in no event exceed a maximum of $4,585,000.

               SECTION 7.6  PROCEDURE FOR INDEMNIFICATION.

               (a) If any third party shall notify a party to this Agreement
        (the "Indemnified Party") with respect to any matter (a "Third Party
        Claim") that may give rise to a claim for indemnification against any
        other party to this Agreement (the "Indemnifying Party") or if any party
        who may make a claim for indemnification under this Agreement otherwise
        becomes aware of any matter that may give rise to such a claim or wishes
        to make such a claim (whether or not related to a Third Party Claim),
        then the Indemnified Party shall promptly notify each Indemnifying party
        thereof in writing; provided, however, that no delay on the part of the
        Indemnified Party in notifying any Indemnifying Party shall relieve the
        Indemnifying Party from any obligation hereunder unless (and then solely
        to the extent) the Indemnifying Party is thereby prejudiced.

               (b) Any Indemnifying Party will have the right to defend the
        Indemnified Party against a Third Party Claim with counsel of its choice
        satisfactory to the Indemnified Party so long as (i) the Indemnifying
        Party notifies the Indemnified Party in writing within a reasonable time
        after the Indemnified Party has given notice of the Third Party Claim
        that the Indemnifying Party will indemnify the Indemnified Party from
        and against the entirety of any adverse consequences (which will
        include, without limitation, all losses, claims, liens, and attorneys'
        fees and related expenses) the Indemnified Party may suffer resulting
        from, arising out of, relating to, in the nature of, or caused by the
        Third Party Claim, (ii) the Indemnifying Party provides the Indemnified
        Party with evidence acceptable to the Indemnified Party that the
        Indemnifying Party will have the financial resources to defend against
        the Third Party Claim and fulfill its indemnification obligations
        hereunder, (iii) the Third Party Claim involves only monetary damages
        and does not seek an injunction or equitable relief or involve the
        possibility of criminal penalties, (iv) settlement of, or adverse
        judgment with respect to the Third Party Claim is not, in the good faith
        judgment of the Indemnified Party, likely to establish a precedential
        custom or practice adverse to the continuing business interests of the
        Indemnified Party, and (v) the Indemnifying Party conducts the defense
        of the Third Party Claim actively and diligently.

                                            -15-
<PAGE>
               (c) So long as the Indemnifying Party is conducting the defense
        of the Third Party Claim in accordance with Section 7.6(b) above, (i)
        the Indemnified Party may retain separate co-counsel at its sole cost
        and expense and participate in the defense of the Third Party Claim,
        (ii) the Indemnified Party will not consent to the entry of any judgment
        or enter into any settlement with respect to the Third Party Claim
        without the prior written consent of the Indemnifying Party (which will
        not be unreasonably withheld) and (iii) the Indemnifying Party will not
        consent to the entry of any judgment or enter into any settlement with
        respect to the Third Party Claim without the prior written consent of
        the Indemnified Party (which will not be unreasonably withheld).

               (d) In the event or to the extent that any of the conditions set
        forth in Section 7.6(b) above is or becomes unsatisfied, however, (i)
        the Indemnified Party may defend against, and consent to the entry of
        any judgment or enter into any settlement with respect to, the Third
        Party Claim and any matter it may deem appropriate in its sole
        discretion and the Indemnified Party need not consult with, or obtain
        any consent from, any Indemnifying Party in connection therewith (but
        will keep the Indemnifying Party reasonably informed regarding the
        progress and anticipated cost thereof), (ii) the Indemnifying Party will
        reimburse the Indemnified Party promptly and periodically for the cost
        of defending against the Third Party Claim (including attorneys' fees
        and expenses) and (iii) the Indemnifying Party will remain responsible
        for any adverse consequences the Indemnified Party may suffer resulting
        from, arising out of, relating to, in the nature of, or caused by the
        Third Party Claim to the fullest extent provided in this Article 7; and
        (iv) the Indemnifying Party shall be deemed to have waived any claim
        that its indemnification obligation should be reduced because of the
        manner in which the counsel for the Indemnified Party handled the Third
        Party Claim.

                               ARTICLE 8. GENERAL

               SECTION 8.1 FURTHER ASSURANCE. From time to time after the
Closing, Seller and Stockholders will, without further consideration, but
without incurring any cost or expense, execute and deliver such other
instruments of conveyance and transfer, and take such other action as Buyer
reasonably may request to more effectively convey and transfer to and vest in
Buyer and to put Buyer in possession of the Assets to be transferred hereunder,
and in the case of contracts and rights, if any, which cannot be transferred
effectively without the consents of third parties, to endeavor to obtain such
consents promptly, and if any be unobtainable, to use their reasonable efforts
to provide Buyer with the benefits thereof in some other manner. Seller and
Stockholders will cooperate and use its reasonable efforts, but without
incurring any cost or expense, to have the present officers, directors and
employees of Seller cooperate with Buyer on and after the Closing in furnishing

of or omission in the exercise of any right, power or remedy accruing to any
party as a result of any breach or default by any other party under this
Agreement shall impair any such right, power or remedy, nor shall it be
construed as a waiver of or acquiescence in any such breach or default, or of or
in any similar breach or default occurring later; not shall any waiver of any
single breach or default be deemed a waiver of any other breach of default
occurring before or after that waiver.

               SECTION 8.4 TIME OF THE ESSENCE. Time is of the essence of this
Agreement.

        Parent shall pay to Seller, on demand, the additional sum of $218,500
        (as interest at the rate of eighteen percent (18%) per annum on the
        $950,000 portion of the Purchase Price which was deferred plus a five
        percent (5%) late payment penalty), together with any other amounts due
        under this Section 8.13.

               (c) Additionally, Parent shall not be in default of its
        obligations to make the payment pursuant to Section 2.1(B) hereof and
        shall not have to pay any amounts under 8.13 (b) hereof in the event
        that on the date such payment is due and payable, there is pending
        litigation related to that certain Executory Agreement between Austin
        Liquids Disposal Co., Inc. ("ALD"), and Enviro-Waste Management, Inc.,
        dated July 1, 1996 (the "Executory Agreement"). After such litigation is
        resolved or Parent receives a written release from ALD to Parent in a
        form satisfactory to Parent releasing Parent, Buyer and their affiliates
        (the "Resolution Date"), Parent shall then make any payment due under
        Section 2.1(B) hereof, less any amounts set off pursuant to Section 11.5
        of the Agreement and Plan of Reorganization among U S Liquids/EMI
        Acquisition Corporation, Parent, Buyer and Stockholders dated of even
        date herewith (the "Merger Agreement"). The terms of Section 8.13(b)
        (including the required notice provisions) shall apply to any failure to
        make payment on the Resolution Date. Parent shall also pay to
        Stockholders interest on such payment from January 16, 1999, at the
        current rate of interest at which Parent is able to borrow funds plus
        two percent (2%) payable monthly in arrears commencing March 1, 1999.

               (d) In any litigation brought by a party over the terms of this
        Agreement, including, without limitation, failure to make required
        payments, the prevailing party shall be entitled to receive, as part of
        its damages, all of its costs and expenses of such litigation,
        including, without limitation, attorney's fees and expenses,
        investigation costs and court costs.

               SECTION 8.14  SIMULTANEOUS CLOSINGS.  The closings under the 
Merger Agreement and that certain Stock Purchase Agreement among Buyer, Parent,
Enviro-Waste Type V of Texas, Inc. and Stockholders shall occur
contemporaneously with the Closing hereunder.

the "Closing Date" as defined in Article 4. Such date shall be deemed the

      be amended to reflect the Articles of Incorporation of Buyer; and,
      subsequent to the Effective Date of the Merger, such Articles of
      Incorporation shall be the Articles of Incorporation of the Surviving
      Corporation until changed as provided by law;

            (ii) the Bylaws of Buyer shall become the Bylaws of the Surviving
      Corporation; and, subsequent to the Effective Date of the Merger, such

      thereafter be duly amended;

            (iii) the officers of Buyer immediately prior to the Effective Date
      of the Merger shall become the officers of the Surviving Corporation, and
      shall hold such offices subject to the provisions of the laws of the State
      of Texas and the Articles of Incorporation and the Bylaws of the Surviving
      Corporation; and

            (iv) the name and address of the person who shall serve as the sole
      member of the Board of Directors of the Surviving Corporation is as

shares and voting rights of each class of outstanding capital stock of Buyer and
Company as of the date of this Agreement are as follows:

            (i) the authorized capital stock of Buyer consists of 1,000 shares

      are issued and outstanding; and

            (ii) the authorized capital stock of Company consists of 100,000
      shares of common stock, without par value per share, of which 3,000 shares

      1.4 EFFECT OF MERGER. Except as herein specifically set forth, the
identity, existence, purposes, powers, objects, franchises, privileges, permits,
licenses, approvals, rights and immunities of Company shall continue unaffected
and unimpaired by the Merger and the corporate franchises, existence and rights
of Buyer shall be merged into Company, and Company, as the Surviving
Corporation, shall be fully vested therewith. At the Effective Date of the
Merger, the separate existence of Buyer shall cease and, in accordance with the
terms of this Agreement, the Surviving Corporation shall possess all the rights,
privileges, permits, licenses, approvals, immunities and franchises, of a public
as well as of a private nature; and all property, real, personal and mixed, and
(except as otherwise expressly set forth herein) debts on whatever account,
including subscriptions to shares, and all other choses in action, and all and
every other interest of or belonging to or due to each of Buyer and Company
shall be taken and deemed to be transferred to, and vested in, the Surviving

privileges, powers and franchises and all and every other interest shall be
thereafter as effectively the property of the Surviving Corporation as they were
of Buyer and Company; and the title to any real estate, or interest therein,
whether by deed or otherwise, vested in Buyer and Company shall be deemed to be
in the Surviving Corporation and shall not revert or be in any way impaired by
reason of the Merger. The Surviving Corporation shall thenceforth be responsible
and liable for all the liabilities and obligations of Buyer and Company and any
claim existing, or action or proceeding pending, by or against Buyer or Company
may be prosecuted as if the Merger had not taken place, or the Surviving
Corporation may be substituted in its place. Neither the rights of creditors nor
any liens upon the property of Buyer or Company shall be impaired by the Merger,
and all debts, liabilities and duties of each of Buyer and Company shall attach
to the Surviving Corporation, and may be enforced against it to the same extent
as if said debts, liabilities and duties had been incurred or contracted by it.

      1.5 DELIVERY OF SHARES. At the Closing, Stockholders, as the holders of
certificates representing all outstanding shares of Company Stock shall, upon
surrender of such certificates, be entitled to receive the consideration set

      1.6 ENDORSEMENT OF COMPANY STOCK. Stockholders shall deliver at Closing
the certificates representing the Company Stock, duly endorsed in blank by
Stockholders or accompanied by stock powers duly endorsed in blank and with all
necessary transfer tax and other revenue stamps, acquired at the Stockholders'
expense, affixed and cancelled. Stockholders, at their sole expense, agree to
cure (both before and after Closing) any deficiencies with respect to the
endorsement of the certificates or other documents of conveyance with respect to
the Company Stock or with respect to the stock powers accompanying the Company
Stock.

2.    CONVERSION AND EXCHANGE OF STOCK.

      2.1 CONVERSION OF STOCK. The manner of converting the shares of Company
Stock issued and outstanding immediately prior to the Effective Date of the
Merger shall be as follows:

            At the Effective Date of the Merger all of the shares of Company
      Stock issued and outstanding immediately prior to the Effective Date of
      the Merger, by virtue of the Merger and without any action on the part of
      the holder thereof, shall automatically be converted into $1,125,000 in
      cash subject to adjustment in accordance with Sections 2.2 and 2.3 below.
      The consideration set forth in this Article 2 shall be allocated among the
      Stockholders in accordance with Annex II attached hereto and made a part
      hereof.

      2.2 ASSUMPTION OF DEBT. Attached hereto as Schedule 2.2 is a listing of
all of the actual long-term debt of Company (including the current portion of
such debt) plus all lease debt (including lease end buy out payments) (the
"Assumed Debt") and evidence establishing the Assumed Debt. If the Assumed Debt
is more than $710,000 on the Closing Date, the consideration payable in Section
2.1 shall be reduced by an amount equal to the difference between $710,000 and
the Assumed Debt.

      2.3 ADJUSTMENT TO PURCHASE PRICE. The parties agree that the purchase
price was determined as if the net working capital of Company, together with
Enviro-Plumbing, Inc. and Enviro-Waste Type V of Texas, Inc. (collectively, the
"Combined Companies"), was going to be $125,000 at the close of business on
December 31, 1997. Accordingly, the parties agree that the purchase price set
forth in this Article 2 shall be adjusted (up or down) on the Adjustment Date
(as defined in Section 10.2) to reflect the actual net working capital of the
Combined Companies on December 31, 1997 (the "Actual Net Working Capital"), as
shown on the balance sheet to be prepared in accordance with Section 10.2
hereof. If the Actual Net Working Capital of the Combined Companies so reflected
is greater than $125,000 on December 31, 1997, then the purchase price paid
pursuant to Section 2.1 shall be increased dollar for dollar for each dollar the
Actual Net Working Capital exceeds $125,000 on December 31, 1997. If the Actual
Net Working Capital of the Combined Companies so reflected is less than $125,000
on December 31, 1997, then the purchase price paid pursuant to Section 2.1 shall
be decreased dollar for dollar for each dollar the Actual Net Working Capital
falls below $125,000 on December 31, 1997. For purposes of this Agreement,
Actual Net Working Capital shall mean the current assets of the Combined
Companies on December 31, 1997, minus all current liabilities of the Combined
Companies (exclusive of the Assumed Debt) on December 31, 1997, calculated in
accordance with the method and principles of accounting used by the Combined
Companies in the

                                    -4-
<PAGE>
preparation of the Combined Companies's financial information delivered pursuant
to Section 5.6 hereof.

      In order to facilitate the contemplated adjustment to purchase price on
the Adjustment Date, at least five business days before December 31, 1997, the
parties will prepare and agree upon an estimated net working capital balance for
the Combined Companies as of November 30, 1997 (the "Estimated Working
Capital"). The amount of Estimated Working Capital (positive or negative) will
be an adjustment to the purchase price on December 31, 1997. In computing the
adjustment amounts provided for this Section, the party owing payment to the
other pursuant to this Section shall make such payment in cash.

      In the event of a dispute between the parties as to the Actual Net Working
Capital, the parties will have 30 days to resolve the dispute among themselves.
If the parties have not resolved such dispute within such 30-day period, then
the parties shall select an arbitrator who shall decide the dispute within 30
days after being selected. If the parties cannot agree on an arbitrator, then
Buyer and Stockholders (as a group) shall each select an arbitrator and the two
arbitrators so selected shall select a third arbitrator. The parties hereto each
agree to be bound by the decision of the arbitrator(s). In the event that three
arbitrators are chosen, a majority decision will be required. Each arbitrator
can be any natural person above the age of 18 and need not have any specific
qualification. All costs of the arbitration shall be split equally between Buyer
and Stockholders (as a group).

reasonable particularity and describes the relevant facts in reasonable detail.

      Wherever a representation or warranty herein is qualified as having been
made "to the best of Stockholders' knowledge", such phrase shall mean the
knowledge of any Stockholder, after reasonable inquiry.

      5.1  ORGANIZATION; AUTHORITY.

      businesses in the places and in the manner as conducted at the time such
      activities were conducted except for where failure to be so authorized,
      qualified or licensed would not have a material adverse affect on the
      Business. Copies of the Company's Articles of Incorporation (certified by
      the Secretary of State of Texas) and Bylaws (certified by the Secretary of
      Company), each as amended, are attached hereto as Schedule 5.1(i). Copies

      11.3  PROCEDURE FOR INDEMNIFICATION WITH RESPECT TO THIRD PARTY CLAIMS.

            (a) If any third party shall notify a party to this Agreement (the
      "Indemnified Party") with respect to any matter (a "Third Party Claim")
      that may give rise to a claim for indemnification against any other party
      to this Agreement (the "Indemnifying Party") or if any party who may make
      a claim for indemnification under this Agreement otherwise becomes aware
      of any matter that may give rise to such a claim or wishes to make such a
      claim (whether or not related to a Third Party Claim), then the
      Indemnified Party shall promptly notify each Indemnifying party thereof in
      writing; provided, however, that no delay on the part of the Indemnified
      Party in notifying any Indemnifying Party shall relieve the Indemnifying
      Party from any obligation hereunder unless (and then solely to the extent)
      the Indemnifying Party is thereby prejudiced.

            (b) Any Indemnifying Party will have the right to defend the
      Indemnified Party against a Third Party Claim with counsel of its choice
      satisfactory to the Indemnified Party so long as (i) the Indemnifying
      Party notifies the Indemnified Party in writing within a reasonable time
      after the Indemnified Party has given notice of the Third Party Claim that
      the Indemnifying Party will indemnify the Indemnified Party from and
      against the entirety of any adverse consequences (which will include,
      without limitation, all

                                    -28-
<PAGE>
      losses, claims, liens, and attorneys' fees and related expenses) the
      Indemnified Party may suffer resulting from, arising out of, relating to,
      in the nature of, or caused by the Third Party Claim, (ii) the
      Indemnifying Party provides the Indemnified Party with evidence acceptable
      to the Indemnified Party that the Indemnifying Party will have the
      financial resources to defend against the Third Party Claim and fulfill
      its indemnification obligations hereunder, (iii) the Third Party Claim
      involves only monetary damages and does not seek an injunction or
      equitable relief or involve the possibility of criminal penalties, (iv)
      settlement of, or adverse judgment with respect to the Third Party Claim
      is not, in the good faith judgment of the Indemnified Party, likely to
      establish a precedential custom or practice adverse to the continuing
      business interests of the Indemnified Party, and (v) the Indemnifying
      Party conducts the defense of the Third Party Claim actively and
      diligently.

            (c) So long as the Indemnifying Party is conducting the defense of
      the Third Party Claim in accordance with Section 12.5(b) above, (i) the
      Indemnified Party may retain separate co-counsel at its sole cost and
      expense and participate in the defense of the Third Party Claim, (ii) the
      Indemnified Party will not consent to the entry of any judgment or enter
      into any settlement with respect to the Third Party Claim without the
      prior written consent of the Indemnifying Party (which will not be
      unreasonably withheld) and (iii) the Indemnifying Party will not consent
      to the entry of any judgment or enter into any settlement with respect to
      the Third Party Claim without the prior written consent of the Indemnified
      Party (which will not be unreasonably withheld).

            (d) In the event or to the extent that any of the conditions set
      forth in Section 12.5(b) above is or becomes unsatisfied, however, (i) the
      Indemnified Party may defend against, and consent to the entry of any
      judgment or enter into any settlement with respect to, the Third Party
      Claim and any matter it may deem appropriate in its sole discretion and
      the Indemnified Party need not consult with, or obtain any consent from,
      any Indemnifying Party in connection therewith (but will keep the
      Indemnifying Party reasonably informed regarding the progress and
      anticipated cost thereof), (ii) the Indemnifying Party will reimburse the
      Indemnified Party promptly and periodically for the cost of defending
      against the Third Party Claim (including attorneys' fees and expenses) and
      (iii) the Indemnifying Party will remain responsible for any adverse
      consequences the Indemnified Party may suffer resulting from, arising out
      of, relating to, in the nature of, or caused by the Third Party Claim to
      the fullest extent provided in this Article 12; and (iv) the Indemnifying
      Party shall be deemed to have waived any claim that its indemnification
      obligation should be reduced because of the manner in which the counsel
      for the Indemnified Party handled the Third Party Claim.

      11.4 LIMITATION ON LIABILITY. The indemnification obligations set forth in
this Agreement shall apply only after the aggregate amount of such obligations
exceed $50,000 when combined with the Stock Purchase Agreement among Company,
Parent, Enviro-Waste Type V of Texas, Inc. and Stockholders (the "Stock Purchase
Agreement") and the Purchase and Sale of Assets Agreement among Company,

suits, proceedings, demands, assessments, adjustments, penalties, losses costs
and expenses whatsoever paid by the Surviving Corporation related to the
Executory Agreement listed in Section 11.1(f) or the surcharge listed in Section
11.1(g) hereof.

the provisions of this Agreement. Any reference to any federal, state, local or
foreign statute shall be deemed to refer to all rules and regulations
promulgated thereunder, unless the context requires otherwise. The word

significance. If any party has breached any representation, warranty or covenant
contained herein in any respect, the fact that there exists another

breached shall not detract from or mitigate the fact the party is in breach of
the first representation, warranty or covenant.

pursuant to Article 13 hereof without the Closing having taken place,
Stockholders will not directly or indirectly solicit offers for Company Stock or

facilitate inquiries or offers from, third parties who express or who have
heretofore expressed an interest in acquiring Company by merger, consolidation
or other combination or acquiring any of Company's assets; nor will they permit

                                       -2-
<PAGE>
               (i) Company is a Texas corporation duly organized, validly
        existing and in good standing under the laws of the State of Texas and
        is now and has been at all times since its creation, duly authorized,
        qualified and licensed under all laws, regulations, ordinances and
        orders of public authorities to carry on its businesses in the places
        and in the manner as conducted at the time such activities were
        conducted except for where failure to be so authorized, qualified or
        licensed would not have a material adverse affect on the Business.
        Copies of the Company's Articles of Incorporation (certified by the
        Secretary of State of Texas) and Bylaws (certified by the Secretary of
        Company), each as amended, are attached hereto as Schedule 5.1(i).

               (ii) Company has full legal right, power and authority (corporate
        and otherwise) to enter into this Agreement and to consummate the
        transactions contemplated by this Agreement. All corporate action of
        Company necessary to approve the sale of the Company Stock has been
        taken, including director and shareholder approvals, if necessary.

               (iii) Each Stockholder is competent and under no legal restraint
        or duress and has the full legal right and capacity to enter into and
        perform his obligations under this Agreement.

        5.2 STOCK OWNERSHIP; ABSENCE OF ADVERSE CLAIMS. All of the issued and
outstanding shares of Company Stock are owned of record and beneficially by
Stockholders as set forth on Annex I and are free and clear of Adverse Claims.
This Agreement is the valid and binding obligation of Company and Stockholders,
enforceable against each of them in accordance with its terms.

        5.3 CAPITALIZATION. The authorized capital stock of Company consists
solely of 50,000 shares of voting common stock, $1.00 par value, of which 1,000
shares are issued and outstanding. All of the issued and outstanding shares of
Company Stock have been duly authorized and validly issued, are fully paid and
nonassessable, were offered, issued, sold and delivered by Company in compliance
with all state and federal laws concerning the issuance of securities and none
of such shares were issued pursuant to awards, grants or bonuses nor in
violation of the preemptive rights of any past or present stockholder. The stock
transfer records provided by Stockholders and Company to Buyer correctly set
forth all issuances, acquisitions and retirements of Company Stock since the
inception of Company. Company has never acquired any treasury stock. No
subscriptions, options, warrants, puts, calls, conversion rights or other
commitments of any kind exist which obligate Company to issue any of its
authorized but unissued capital stock or otherwise relate to the sale or
transfer by Company of any securities of Company (whether debt or equity). In
addition, Company has no obligation (contingent or otherwise) to purchase,
redeem or otherwise acquire any of its equity securities or any interests
therein or to pay any dividend or make any distribution in respect thereof.
Company has not agreed to register any securities under the Securities Act of
1933, as amended (the "Act"), or under any state securities law.

5.4, Company has never directly or indirectly participated in any manner in any
joint venture, partnership or

                                       -3-
<PAGE>
other noncorporate entity. Company was formed solely to operate the Business and
has never conducted any other business or activity. Also set forth on Schedule
5.4 is a list of the names of all predecessors of Company, all prior corporate
names of Company, and all trade names and "doing business as" names of Company,
including the names of all entities substantially all of the assets of which
were previously acquired by Company.

        5.5 NO SUBSIDIARIES. Company has never owned or controlled and does not
now own, of record or beneficially, or control, directly or indirectly, any
capital stock, securities convertible into capital stock or any other equity
interest in any partnership, corporation, association or other business entity
other than those of Company.

reasonably expected to be incurred from such risks. Since its inception Company
has not (a) made any material change in its accounting policies or (b) effected
any prior period adjustment to, or other restatement of, its financial
statements for any period. The Financial Statements are consistent with the
books and records of Company (which books and records are correct and complete).

complete and accurate list as of the date hereof of all liabilities and
obligations of Company, excluding obligations arising under this Agreement,
which are not individually reflected in the Financial Statements dated the

kind, character and description, accrued or unaccrued, absolute or contingent,

        may make a claim for indemnification under this Agreement otherwise
        becomes aware of any matter that may give rise to such a claim or wishes
        to make such a claim (whether or not related to a Third Party Claim),
        then the Indemnified Party shall promptly notify each Indemnifying party
        thereof in writing; provided, however, that no delay on the part of the
        Indemnified Party in notifying any Indemnifying Party shall relieve the

        to the extent) the Indemnifying Party is thereby prejudiced.

                                            -20-
<PAGE>
               (b) Any Indemnifying Party will have the right to defend the
        Indemnified Party against a Third Party Claim with counsel of its choice
        satisfactory to the Indemnified Party so long as (i) the Indemnifying
        Party notifies the Indemnified Party in writing within a reasonable time
        after the Indemnified Party has given notice of the Third Party Claim
        that the Indemnifying Party will indemnify the Indemnified Party from
        and against the entirety of any adverse consequences (which will
        include, without limitation, all losses, claims, liens, and attorneys'
        fees and related expenses) the Indemnified Party may suffer resulting
        from, arising out of, relating to, in the nature of, or caused by the
        Third Party Claim, (ii) the Indemnifying Party provides the Indemnified
        Party with evidence acceptable to the Indemnified Party that the
        Indemnifying Party will have the financial resources to defend against
        the Third Party Claim and fulfill its indemnification obligations
        hereunder, (iii) the Third Party Claim involves only monetary damages
        and does not seek an injunction or equitable relief or involve the
        possibility of criminal penalties, (iv) settlement of, or adverse
        judgment with respect to the Third Party Claim is not, in the good faith
        judgment of the Indemnified Party, likely to establish a precedential
        custom or practice adverse to the continuing business interests of the
        Indemnified Party, and (v) the Indemnifying Party conducts the defense
        of the Third Party Claim actively and diligently.

               (c) So long as the Indemnifying Party is conducting the defense
        of the Third Party Claim in accordance with Section 12.5(b) above, (i)
        the Indemnified Party may retain separate co-counsel at its sole cost
        and expense and participate in the defense of the Third Party Claim,
        (ii) the Indemnified Party will not consent to the entry of any judgment
        or enter into any settlement with respect to the Third Party Claim
        without the prior written consent of the Indemnifying Party (which will
        not be unreasonably withheld) and (iii) the Indemnifying Party will not
        consent to the entry of any judgment or enter into any settlement with
        respect to the Third Party Claim without the prior written consent of
        the Indemnified Party (which will not be unreasonably withheld).

               (d) In the event or to the extent that any of the conditions set
        forth in Section 12.5(b) above is or becomes unsatisfied, however, (i)
        the Indemnified Party may defend against, and consent to the entry of
        any judgment or enter into any settlement with respect to, the Third
        Party Claim and any matter it may deem appropriate in its sole
        discretion and the Indemnified Party need not consult with, or obtain
        any consent from, any Indemnifying Party in connection therewith (but
        will keep the Indemnifying Party reasonably informed regarding the
        progress and anticipated cost thereof), (ii) the Indemnifying Party will
        reimburse the Indemnified Party promptly and periodically for the cost
        of defending against the Third Party Claim (including attorneys' fees
        and expenses) and (iii) the Indemnifying Party will remain responsible
        for any adverse consequences the Indemnified Party may suffer resulting
        from, arising out of, relating to, in the nature of, or caused by the
        Third Party Claim to the fullest extent provided in this Article 12; and
        (iv) the Indemnifying Party shall be deemed to have waived any claim
        that its indemnification obligation should be reduced because of the
        manner in which the counsel for the Indemnified Party handled the Third
        Party Claim.

        14.11 CAPTIONS. The headings of this Agreement are inserted for
convenience only, shall not constitute a part of this Agreement or be used to
construe or interpret any provision hereof.

        14.12 SEVERABILITY. In case any provision of this Agreement shall be
invalid, illegal or unenforceable, it shall, to the extent possible, be modified
in such manner as to be valid, legal and enforceable but so as most nearly to
retain the intent of the parties. If such modification is not possible, such
provision shall be severed from this Agreement. In either case the validity,
legality and enforceability of the remaining provisions of this Agreement shall
not in any way be affected or impaired thereby.

        14.13 CONSTRUCTION. The parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the parties and no presumption or burden of proof shall
arise favoring or disfavoring any party by virtue of the authorship of any of
the provisions of this Agreement. Any reference to any federal, state, local or
foreign statute shall be deemed to refer to all rules and regulations
promulgated thereunder, unless the context requires otherwise. The word
"including" means including, without limitation. The parties intend that
representation, warranty and covenant contained herein shall have independent
significance. If any party has breached any representation, warranty or covenant
contained herein in any respect, the fact that there exists another
representation, warranty or covenant relating to the same subject matter
(regardless of the relative levels of specificity) that the party has not
breached shall not detract from or mitigate the fact the party is in breach of
the first representation, warranty or covenant.

        14.14 STANDSTILL AGREEMENT. Unless and until this Agreement is
terminated pursuant to Article 13 hereof without the Closing having taken place,
Stockholders will not directly or indirectly solicit offers for Company Stock or
the assets of Company or a merger or consolidation involving Company from, or
respond to inquiries from, share information with, negotiate with or in any way
facilitate inquiries or offers from, third parties who express or who have
heretofore expressed an interest in acquiring Company by merger, consolidation
or other combination or acquiring any of Company's assets; nor will they permit
Company to do any of the foregoing.

               SECTION 1.3 NON-ASSIGNMENT OF CERTAIN CUSTOMER ACCOUNTS.
Notwithstanding anything to the contrary in this Agreement, to the extent that
the assignment hereunder of any Customer Account shall require the consent of
any third party, neither this Agreement nor any action taken pursuant to its
provisions shall constitute an assignment or an agreement to assign if such
assignment or attempted assignment would constitute a breach thereof or result
in the loss or diminution thereof; provided, however, that in each such case,
Seller shall use its best efforts to obtain the consent of such other party to
such assignment to Buyer. If such consent is not obtained, Seller shall
cooperate with Buyer in any reasonable arrangement designed to provide for Buyer
the benefits under any such Customer Account, including, without limitation, an
adjustment of the purchase price set forth in Section 2.1 hereof and enforcement
for the account and benefit of Buyer, of any and all rights of Seller against
any other person arising out of the breach or cancellation of any such Customer
Account by such other person, or otherwise. Attached hereto as Schedule 1.3 is a
list of all Customer Accounts requiring consent to their assignment.

               SECTION 1.4  SELLER ACCOUNTS RECEIVABLE.

               (a) Buyer shall have no liability or obligation whatsoever to
        Seller in connection with the Accounts Receivable and Buyer shall not be
        responsible for collecting the Accounts Receivable. However, if Buyer
        receives any payments which are designated by the customer as being
        toward such Accounts Receivable, then Buyer shall forward such payments
        to Seller as set forth in Section 1.4(b). Attached hereto as Schedule
        1.4 is a true and complete list of all Accounts Receivable of Seller as
        of January 1, 1998.

               (b) All sums representing Accounts Receivable as set forth on
        Schedule 1.4 collected by Buyer from the customers

                                            -3-
<PAGE>
        set forth on Schedule 1.1(d) shall be conclusively presumed to be
        receipts from the collection of the oldest Accounts Receivable of such
        customer unless the customer specifically indicates otherwise in
        writing. All such sums received by Buyer shall be received in trust and
        shall be remitted to Seller on a regular basis (but at least monthly),
        together with an itemized list of the sources thereof. Seller shall be
        entitled to take such action as may be necessary in order to collect its
        unpaid Accounts Receivable; provided, however, that Seller agrees not to
        deliver any such Accounts Receivable to a collection agency or institute
        any litigation related to an Accounts Receivable without the prior
        written consent of Buyer, which consent shall not be unreasonably
        withheld.

               SECTION 1.5 PRORATION OF CASH ON HAND. Seller shall pay all
expenses and be entitled to all revenues related to the Business up to and
including the close of business on December 31, 1997. Commencing January 1,
1998, Buyer shall pay all expenses and be entitled to all revenues related to
the Business. The parties agree that on or before 90 days after the Closing Date
they will conduct a final accounting of such revenues and expenses and the party
owing any additional adjustment shall make payment in cash within seven business
days thereafter.

               SECTION 1.6 CHANGE OF NAME. On the date of Closing, Seller shall
take all necessary action to change Seller's current Business Name, to a name
not the same as or similar to Suburban Wastewater Services Inc. or any other
symbol, trademark, service mark, logo or trade name now used by Seller. Seller
shall, on the date of closing, deliver to Buyer, in form suitable for filing,
such certificates, consents and other documents as are necessary to effect the
transfer of the registration of the Business Name conveyed by Buyer pursuant to
this Agreement in Massachusetts and shall grant any consents and take any other
and further action, all at Seller's own expense, requested by Buyer to enable
Buyer to reserve or register any such name for use of Buyer in Massachusetts.
Notwithstanding the foregoing, Seller currently uses the name "Suburban" in
other contexts and may continue to do so after the date of Closing.

               ARTICLE 5. REPRESENTATIONS AND WARRANTIES OF SELLER
                                AND STOCKHOLDERS

               SECTION 5.1 Seller and Stockholders, jointly and severally,
represent and warrant to Buyer that:

               (a)    AUTHORITY.

                      (i) Seller is a corporation duly formed, validly existing
               and in good standing under the laws of the Commonwealth of
               Massachusetts. The execution and delivery of this Agreement, the
               consummation of the transactions contemplated hereby and the
               compliance by Seller and Stockholders with the terms of this
               Agreement do not and will not conflict with or result in a breach
               of any terms of, or constitute a default under, the Articles of
               Incorporation or Bylaws of Seller, or any instrument or other
               agreement to which Seller or Stockholders are a party or by which
               Seller or Stockholders are bound. This Agreement constitutes a
               valid obligation of Seller and Stockholders enforceable against
               Seller and Stockholders in accordance with its terms except as
               limited by bankruptcy, insolvency, reorganization or other such
               laws concerning the rights of creditors.

                                            -8-
<PAGE>
                   (ii) Stockholders are each competent, under no duress or
               legal restraint, and have all necessary authority to enter into
               this Agreement, perform their obligations hereunder and
               consummate the transactions contemplated hereby.

                  (iii) All of the issued and outstanding shares of Seller are
               owned of record and beneficially by Stockholders, free and clear
               of all liens, security interests and encumbrances whatsoever.

               (b) COMPLIANCE WITH LAW. Neither Seller nor any of the
        Stockholders, to the best of their knowledge, is in default under any
        applicable federal, state or local laws, statutes, ordinances, permits,
        licenses, orders, approvals, variances, rules or regulations or judicial
        or administrative decisions ("Applicable Laws") which would have an
        adverse effect upon the Assets or the Business. Seller has been granted
        all licenses, permits, consents, authorizations and approvals from
        federal, state and local government regulatory bodies necessary or
        desirable to carry on the Business, all of which are currently in full
        force and effect. To the best knowledge of Seller and Stockholders, each
        of the Assets complies in all respects with all federal, state and local
        laws, statutes, ordinances, permits, licenses, approvals, rules and
        regulations applicable thereto.

               (c) EQUIPMENT. Listed on Schedule 1.1(a) hereto is a complete and
        accurate list of all Equipment used or for use in connection with the
        Business. Each piece of Equipment is in good working order and repair.

               (d) ROLLING STOCK. Listed on Schedule 1.1(b) hereto is a complete
        and accurate list of all Rolling Stock. Each motor vehicle, attachment,
        accessory and piece of materials handling equipment comprising the
        Rolling Stock is in good working order and repair.

               (e) CUSTOMER ACCOUNTS. Listed on Schedule 1.1(d) hereto is a
        complete and accurate list of the Customer Accounts as of the date
        hereof. Except as set forth on Schedule 1.3, all Customer Accounts are
        (and will be immediately following the Closing) in full force and effect
        and are valid, binding and enforceable against the respective parties
        thereto in accordance with their respective provisions, and Seller is
        not in default in, nor has there occurred an event or condition
        (including Seller's execution and delivery of or performance under this
        Agreement) which with the passage of time or the giving of notice (or
        both) would constitute a default, with regard to the payment or
        performance of any obligation under any Customer Account; no claim of
        such a default has been asserted and there is no reasonable basis upon
        which such a claim could validly be made. Neither Seller nor
        Stockholders

                                            -9-
<PAGE>
        has received any notice that any person intends or desires to modify,
        waive, amend, rescind, release, cancel or terminate any Customer
        Account. By virtue of the grant, conveyance, sale, transfer and
        assignment of the Customer Accounts by Seller to Buyer hereunder, Buyer
        shall own and hold all right, title and interest of Seller in and to the
        Customer Accounts, without the consent or approval of any other person
        or entity.

               (f) TITLE TO THE PERSONAL PROPERTY. Seller has good and
        marketable title to all of the Assets constituting personal property,
        free and clear of all liens, encumbrances, security interests, equities
        or restrictions whatsoever except the Assumed Debt and, by virtue of the
        grant, conveyance, sale, transfer, and assignment of the Assets
        hereunder, Buyer shall receive good and marketable title to all of the
        Assets constituting personal property, free and clear of all liens,
        lease payments (including lease-end buy-out payments), encumbrances,
        security interests, equities or restrictions whatsoever except the
        Assumed Debt. The Assets include all of the permits, licenses,
        franchises, consents and other approvals necessary or desirable to
        conduct the Business.

               (g) TITLE TO REAL PROPERTY. Seller has never owned, leased or
        otherwise occupied, had an interest in or operated any real property
        other than the Land. Seller has good, leasehold title to the Land.
        Attached hereto as Schedule 5.1(g) is a true and complete copy of the
        lease for the Land.
        Except as set forth on Schedule 5.1(g):

                      (i) The Land is, and at all times during operation of the
               Business has been, fully licensed, permitted and authorized for
               the operation of the Business under all Applicable Laws relating
               to the protection of the environment, the Land and the conduct of
               the Business thereon (including, without limitation, all zoning
               restrictions and land use requirements).

                   (ii) The Land is usable for its current uses and can be used
               by Buyer after the Closing for such uses without violating any
               applicable law or private restriction, and such uses are legal
               conforming uses. There are no proceedings or amendments pending
               and brought by or, to the best of Seller's knowledge, threatened
               by, any third party which would result in a change in the
               allowable uses of the Land or which would modify the right of
               Buyer to use the Land for its current uses after the Closing
               Date.

               (h) LITIGATION. Except as set forth on Schedule 5.1(h) hereof,
        there is no claim, litigation, action, suit or proceeding,
        administrative or judicial, pending or threatened against Seller or
        Stockholders, or involving the Assets or the Business, at law or in
        equity, before any federal, state or

                                      -10-
<PAGE>
        local court or regulatory agency, or other governmental authority.
        Neither Seller nor Stockholders has received any notice of any of the
        above and no facts or circumstances exist which would, with the passage
        of time or giving of notice (or both), give rise to any of the above.

               (i) EMPLOYEES. Attached as Schedule 5.1(i) hereof is a complete
        list of all employees of Seller and their respective rates of
        compensation (including a breakdown of the portion thereof attributable
        to salary, bonus and other compensation, respectively) as of the date of
        Closing. Each employee is an employee at will and there are no
        collective bargaining agreements affecting any employee of Seller. Buyer
        shall not be obligated to hire any of Seller's employees.

               (j) EMPLOYEE RELATIONS AND BENEFIT PLANS. Set forth on Schedule
        5.1(j) is an accurate and complete list of all agreements of any kind
        between Seller and its employees or group of employees, including,
        without limitation, employment agreements, collective bargaining
        agreements and benefit plans. Buyer shall not, by the execution and
        delivery of this Agreement or otherwise, become obligated to or assume
        any liabilities or contractual obligations with respect to any employee
        of Seller or otherwise become liable for or obligated in any manner
        (contractual or otherwise) to any employee of Seller, including, without
        limiting the generality of the foregoing, any liability or obligation
        pursuant to any collective bargaining agreement, employment agreement,
        or pension, profit sharing or other employee benefit plan (within the
        meaning of Section 3(3) of the Employment Retirement Income Security Act
        of 1974, as amended) or any other fringe benefit program maintained by
        Seller or to which Seller contributes or any liability for the
        withdrawal or partial withdrawal from or termination of any such plan or
        program by Seller.

               (k) FINANCIAL STATEMENTS. Seller has delivered to Buyer copies of
        Seller's balance sheet as of October 31, 1997 (the "Balance Sheet
        Date"), and a statement of income, cash flow and retained earnings for
        the period then ended (the "Financial Statements"). The Financial
        Statements (including any footnotes thereto) have been prepared in
        accordance with GAAP, applied on a consistent basis throughout the
        periods indicated. The Financial Statements (including all footnotes
        thereto) are true, complete and correct and present fairly the financial
        condition and the results of the operations of Seller for the period
        indicated thereon. All reserves for contingent risks have been estimated
        in accordance with GAAP and are appropriate and sufficient to cover all
        costs reasonably expected to be incurred from such risks. The Financial
        Statements are consistent with the books and records of Seller (which
        books and records are correct and complete).

                                            -11-
<PAGE>
               (l) TAXES. No federal, state, local or other tax returns or
        reports filed by Seller (whether filed prior to, on or after the date
        hereof) with respect to the Business or the Assets will result in any
        taxes, assessments, fees or other governmental charges upon the Assets
        or Buyer, whether as a transferee of the Assets or otherwise. All
        federal, state and local taxes due and payable with respect to the
        Business or the Assets have been paid, including, without limiting the
        generality of the foregoing, all federal, state and local income, sales,
        use, franchise, excise and property taxes.

               (m) HAZARDOUS MATERIALS. To the best of Seller's and
        Shareholders' knowledge, neither Seller nor Stockholders has ever
        generated, transported, stored, handled, recycled, reclaimed, disposed
        of, or contracted for the disposal of, hazardous materials, hazardous
        wastes, hazardous substances, toxic wastes or substances, infectious or
        medical waste, radioactive waste or sewage sludges as those terms are
        defined by the Resource Conservation and Recovery Act of 1976; the
        Comprehensive Environmental Response, Compensation and Liability Act of
        1980 ("CERCLA"); the Atomic Energy Act of 1954; the Toxic Substances
        Control Act; the Occupational Health and Safety Act; any comparable or
        similar Massachusetts statute; or the rules and regulations promulgated
        under any of the foregoing, as each of the foregoing may have been from
        time to time amended (collectively, "Hazardous Materials"). Seller has
        never owned, operated, had an interest in, engaged in and/or leased a
        waste transfer, recycling, treatment, storage or disposal facility,
        business or activity other than the Business. Seller has obtained and
        maintained all necessary trip tickets, signed by the applicable waste
        generators, and other records demonstrating the nature of the waste
        transported in connection with the Business. To the best of Seller's and
        Stockholders' knowledge, no employee, contractor or agent of Seller has,
        in the course and scope of employment with Seller, been harmed by
        exposure to Hazardous Materials. To the best of Seller's and
        Stockholders' knowledge, Seller has no direct or contingent liability or
        obligation for or in connection with any claimed release, discharge or
        leak of any substance onto the Land or into the environment. Further, to
        the best of Seller's and Stockholders' knowledge, no portion of the Land
        is listed on the CERCLA list or the National Priorities List of
        Hazardous Waste Sites or any similar list maintained by the Commonwealth
        of Massachusetts. Attached hereto as Schedule 5.1(m) is a complete list
        of the names and addresses of all disposal sites at any time now or in
        the past utilized by Seller, none of which sites, to the best of
        Seller's and Stockholders' knowledge, is listed on the CERCLA list or
        the National Priorities List of Hazardous Waste Sites or any comparable
        Massachusetts list. Neither Seller nor Stockholders is listed as a
        potentially responsible party under CERCLA or any comparable or similar
        Massachusetts statute; neither Seller

                                      -12-
<PAGE>
        nor Stockholders has received any notice of such a listing; and neither
        Seller nor Stockholders knows of any facts or circumstances which could
        give rise to such a listing.

               (n) GOVERNMENT NOTICES. Seller has delivered to Buyer, a
        description and copies, as of the date of this Agreement, of all
        notifications, filed or submitted, or required to be filed or submitted,
        to governmental agencies and of all material notifications from such
        governmental agencies relating to Seller and the Assets or relating to
        the discharge or release of materials into the environment or otherwise
        relating to the protection of the public health or the environment.

               (o) ABSENCE OF PRICE RENEGOTIATION CONTRACTS. Seller is not now
        nor has ever been a party to any governmental contracts subject to price
        redetermination or renegotiation.

               (p) GROSS REVENUES. Set forth on Schedule 5.1(p) are the gross
        revenues generated by the Business for the 12-month period immediately
        preceding the month in which the Closing occurs.

               (q) UNDERGROUND STORAGE TANKS. Except for the Land, Seller has
        never owned, leased or operated any real estate having any underground
        storage tanks containing petroleum products or wastes or other hazardous
        substances regulated by 40 CFR 280 and/or other applicable federal,
        state or local laws, rules and regulations and requirements. Set forth
        on Schedule 5.1(q) is a list of all above and below ground tanks located
        on the Land, each of which are being used and maintained in accordance
        with Applicable Laws.

               (r) COMPLETENESS OF DISCLOSURE. This Agreement and the Schedules
        hereto and all other documents and information furnished to Buyer and
        its representatives pursuant hereto do not and will not include any
        untrue statement of a material fact or omit to state a material fact
        necessary to make the statements therein not misleading. If Seller or
        Stockholders become aware of any fact or circumstance which would change
        a representation or warranty of Seller or Stockholders in this
        Agreement, the party with such knowledge shall immediately give notice
        of such fact or circumstance to Buyer. However, such notification shall
        not relieve Seller or Stockholders of their obligations under this
        Agreement, and at the sole option of Buyer, the truth and accuracy of
        any and all warranties and representations of Seller and Stockholders at
        the date of this Agreement shall be a precondition to the consummation
        of this transaction.

               SECTION 5.2 SURVIVAL. Each of the representations and warranties
set forth in this Article 5 shall survive the Closing and the transfer of the
Assets, in accordance with Article 8 hereof.

        Agreement, the consummation of the transactions contemplated hereby and
        the compliance by Buyer and Parent with the terms of this Agreement do
        not and will not conflict with or result in a breach of any terms of, or
        constitute a default under, Buyer's Articles of Incorporation or Bylaws
        or any other agreement or instrument to which Buyer or Parent is a party
        or by which Buyer or Parent is bound. All necessary corporate action has
        been taken by Buyer and Parent with respect to the execution and
        delivery of this Agreement, and this Agreement constitutes a valid
        obligation of Buyer and Parent enforceable in accordance with its terms
        except as limited by bankruptcy, insolvency, reorganization or other
        such laws concerning the rights of creditors.

               (c) PARENT STOCK. The Parent Stock to be delivered to Seller in
        connection with this Agreement, when delivered in accordance with the

               (i) engage, whether as a corporation on its own account, or as an
        officer, director, shareholder, owner, partner, joint venturer,
        investor, agent, or in a managerial capacity, whether as an employee,
        independent contractor, consultant or advisor, or as a sales
        representative, in the business of: siting, developing, constructing,
        permitting or operating a facility for the processing, treatment or
        disposal of nonhazardous liquid waste (including, without limitation,
        waste oil, waste water, grease trap waste, grit trap waste and oil
        contaminated water); and transportation or collection of any such
        materials, in each case within a radius of 100 air miles of Braintree,
        Massachusetts (the "Territory");

            (ii) call upon any person who is, at that time, within the
        Territory, an employee of Buyer in a managerial capacity for the purpose
        or with the intent of enticing such employee away from or out of the
        employ of Buyer;

           (iii) call upon any person or entity which is, at that time, or which
        has been, within one year prior to that time, a customer of Seller or
        Buyer, as the case may be, within the Territory for the purpose of:
        siting, developing, constructing, permitting or operating a facility for
        the processing, treatment or disposal of non-hazardous liquid waste
        (including, without limitation, waste oil, waste water, grease trap
        waste, grit trap waste and oil contaminated water); and transportation
        or collection of any such materials, in each case within the Territory;

            (iv) call upon any prospective acquisition candidate, on their own
        behalf or on behalf of any competitor, which candidate was either called
        upon by Seller or Stockholders or for which Seller or Stockholders made
        an acquisition analysis for Seller or Buyer;

               (v) disclose the identity of Buyer's customers, whether in
        existence or proposed, to any person, firm, partnership, corporation or
        business for any reason or purpose whatsoever; or

            (vi) promote or assist, financially or otherwise (including, without
        limitation, lending, guaranteeing loans or otherwise providing financial
        assurance in any way), any person, firm, partnership, corporation or
        other entity whatsoever to do any of the above.

               Notwithstanding the above, the foregoing covenant shall not be
deemed to prohibit Seller or Stockholders from acquiring as an investment not
more than one percent of the capital stock of a competing business, whose stock
is traded on a national securities exchange or over-the-counter.

               SECTION 7.2 INJUNCTIVE RELIEF. Because of the difficulty of
measuring economic losses to Buyer as a result of the breach of the foregoing
covenant, and because of the immediate and irreparable damage that would be
caused to Buyer for which it would have no other adequate remedy, Seller and
Stockholders agree that, in the event of breach by any of them of the foregoing
covenant, the covenant may be enforced by Buyer by, without limitation,
injunctions and restraining orders.

               SECTION 7.3 REASONABLENESS OF COVENANTS. It is agreed by the
parties that the foregoing covenants in this Section 7 impose a reasonable
restraint on Seller and Stockholders in light of the activities and business of
the Buyer on the date of the execution of this Agreement and the future plans of
the Buyer.

               SECTION 7.4 SEVERABILITY OF COVENANTS. The covenants in this
Section 7 are severable and separate, and the unenforceability of any specific
covenant shall not affect the provisions of any other covenant. Moreover, in the
event any court of competent jurisdiction shall determine that the scope, time
or territorial restrictions set forth are unreasonable, then it is the intention
of the parties that such restrictions be enforced to the fullest extent which
the court deems reasonable, and the Agreement shall thereby be reformed.

               SECTION 7.5 INDEPENDENT COVENANTS. All of the covenants in this
Section 7 shall be construed as an agreement independent of any other provision
of this Agreement, and the existence of any claim or clause of action of Seller
or Stockholders against Buyer, whether predicated on this Agreement or
otherwise, shall not constitute a defense to the enforcement by Buyer of such
covenants. It is specifically agreed that the duration of the noncompetition
covenants stated above shall be computed by excluding from such computation any
time during which Seller or Stockholders is in violation of any provision of
this Section 7 and any time during which there is pending in any court of
competent jurisdiction any action (including any appeal from any judgment)
brought by any person, whether or not a party to this Agreement, in which action
Buyer seeks to enforce the agreements and covenants of Seller or Stockholders or
in which any person contests the validity of such agreements and covenants or
their enforceability or seeks to avoid their performance or enforcement.

               SECTION 7.6 MATERIALITY. Seller and Stockholders hereby agree
that the foregoing noncompetition covenants are a material and substantial part
of this transaction.

            ARTICLE 8. NON-ASSUMPTION OF LIABILITIES; INDEMNIFICATION

               SECTION 8.1  NON-ASSUMPTION OF LIABILITIES.  Except as
explicitly set forth in Section 8.2 below, Buyer shall not, by the
execution and performance of this Agreement or otherwise, assume,

                                      -16-

become responsible for or incur any liability or obligation of any nature of
Seller or Stockholders whether legal or equitable, matured or contingent, known
or unknown, foreseen or unforeseen, ordinary or extraordinary, patent or latent,
whether arising out of occurrences prior to, at or after the date of this
Agreement, including, without limiting the generality of the foregoing, any
liability or obligation arising out of or relating to: (a) any occurrence or
circumstance (whether known or unknown) which occurs or exists on or prior to
the date of this Agreement and which constitutes, or which by the lapse of time
or giving notice (or both) would constitute, a breach or default under any
lease, contract, or other instrument or agreement (whether written or oral); (b)
any injury to or death of any person or damage to or destruction of any
property, whether based on negligence, breach of warranty, or any other theory;
(c) a violation of the requirements of any governmental authority or of the
rights of any third person, including, without limitation, any requirements
relating to the reporting and payment of federal, state, local or other income,
sales, use, franchise, excise or property tax liabilities of Seller or
Stockholders; (d) the generation, collection, transportation, storage or
disposal by Seller or Stockholders of any materials, including, without
limitation, Hazardous Materials; (e) an agreement or arrangement between Seller
and the employees of Seller or Stockholders or any labor or collective
bargaining unit representing any such employees; (f) the severance pay
obligation of Seller or any employee benefit plan (within the meaning of Section
3(3) of the Employee Retirement Income Security Act of 1974, as amended) or any
other fringe benefit program maintained or sponsored by Seller or Stockholders
or to which Seller or Stockholders contributes or any contributions, benefits or
liabilities therefor or any liability for the withdrawal or partial withdrawal
from or termination of any such plan or program by Seller or Stockholders; (g)
the debts of Seller or Stockholders other than the Assumed Debt; (h) any
litigation against Seller or Stockholders, whether or not listed on Schedule
5.1(h); (i) any liability, obligation, cost or expense related to the Excluded
Assets; (j) any liability, obligation cost or expense related to the Land
related to the time prior to the Closing Date, including, without limitation,
the environmental condition thereof; and (k) the liabilities or obligations of
Seller or Stockholders for brokerage or other commissions relative to this
Agreement or the transactions contemplated hereunder. Seller and Stockholders
each agree to indemnify Buyer, its successors and assigns from and against all
of the above liabilities and obligations in accordance with Section 8.3 below.

               SECTION 8.2 ASSUMPTION OF SPECIFIC LIABILITIES. In addition to
the payment of the Assumed Debt, Buyer agrees to perform all of Seller's
contractual obligations related to the Customer Contracts to the extent, and
only to the extent, such obligations first mature and are required to be
performed after the close of business on the Closing Date.

               SECTION 8.3 INDEMNIFICATION BY SELLER AND STOCKHOLDERS.

and Stockholders, jointly and severally, agree to defend, indemnify and hold
harmless Buyer, its officers, shareholders, directors, divisions, subdivisions,
affiliates, parent, employees, agents, successors, assigns and the Assets from
and against all losses, claims, actions, causes of action, damages, liabilities,
expenses and other costs of any kind or amount whatsoever (including, without
limitation, reasonable attorneys' fees), whether equitable or legal, matured or
contingent, known or unknown, foreseen or unforeseen, ordinary or extraordinary,
patent or latent, which result, either before or after the date of this
Agreement, from:

               (a) inaccuracy in any representation or warranty made by Seller 
        or Stockholders in this Agreement;

               (b) breach of any representation or warranty under this Agreement
        by Seller or Stockholders;

               (c) failure of Seller or Stockholders duly to perform and observe
        any term, provision, covenant, agreement or condition under this
        Agreement;

               (d) liability of Seller or Stockholders imposed upon Buyer
        (including, without limitation, all liability for the generation,

        including, without limitation, Hazardous Materials, whether or not
        disclosed on Schedule 5.1(m) hereof);

               (e) misrepresentation in or omission from any Schedule to this
        Agreement;

               (f) failure of Seller or Stockholders to obtain consent to a
        Customer Account requiring such consent (including, without limitation,
        reimbursement to Buyer of the value of such nonassigned Customer
        Account);

               (g) liability of Seller or Stockholders resulting from one or

        5.1(h);

               (h) liability of Seller or Stockholders to creditors of Seller or
        Stockholders which is imposed on Buyer whether as a result of bankruptcy
        proceedings or otherwise and whether as an account payable by Seller or
        Stockholders or as a claim of alleged fraudulent conveyance or
        preferential payments within the meaning of the United States Bankruptcy
        Code or otherwise; and

               (i) the existence of creditors of Seller which are not disclosed
        to Buyer;

                                      -18-
<PAGE>
               (j) any of the matters described in Section 8.1(a)-(k) hereof; 
        and

               (k) subject to Section 8.5 hereof, any claim by a third party
        that, if true, would mean that a condition for indemnification set forth
        in this Section 8.3 had been satisfied.

Buyer shall be deemed to have suffered such loss, claim, action, cause of
action, damage, liability, expense or other cost, or to have paid or to have
become obligated to pay any sum on account, of, the matters referred to in
subparagraphs (a) - (l) of this Section 8.3 if the same shall be suffered, paid
or incurred by Buyer or any parent, subsidiary, affiliate, or successor of
Buyer. The amount of the loss, claim, action, cause of action, damage,
liability, expense or other cost deemed to be suffered, paid or incurred by
Buyer shall be an amount equal to the loss, claim, action, cause of action,
damage, liability, expense or other cost suffered, paid or incurred by such
parent, subsidiary, affiliate, or successor.

               SECTION 8.4 PROCEDURE FOR INDEMNIFICATION. Promptly after a party
hereto (hereinafter the "Indemnified Party") has received notice of or has
knowledge of any claim by a person not a party to this Agreement ("Third
Person") or the commencement of any action or proceeding by a Third Person, the
Indemnified Party shall, as a condition precedent to a claim with respect
thereto being made against any party obligated to provide indemnification
pursuant to this Agreement (hereinafter the "Indemnifying Party"), give the
Indemnifying Party written notice of such claim or the commencement of such
action or proceeding (the "Notice"). The Notice shall state the nature and the
basis of such claim and a reasonable estimate of the amount thereof. The
Indemnifying Party, after receipt of the Notice, shall defend and settle, at its
own expense and by its own counsel, each such matter so long as the Indemnifying
Party pursues the same diligently and in good faith and the claim does not
involve injunctive or equitable relief or involve the possibility of criminal
penalties. The Indemnified Party shall cooperate with the Indemnifying Party and
its counsel in the defense thereof and in any settlement thereof. Such
cooperation shall include, but shall not be limited to, furnishing the
Indemnifying Party with any books, records or information reasonably requested
by the Indemnifying Party that are in the Indemnified Party's possession or
control. Notwithstanding the foregoing, the Indemnified Party shall have the
right to participate in any matter through counsel of its own choosing at its
own expense, provided that the Indemnifying Party's counsel shall always be lead
counsel and shall determine all litigation and settlement steps, strategy and
the like. After the Indemnifying Party has received the Notice, the Indemnifying
Party shall not be liable for any additional legal expenses incurred by the
Indemnified Party in connection with any defense or settlement of such asserted
liability, except to the extent such participation is

                                            -19-
<PAGE>
requested by the Indemnifying Party, in which event the Indemnified Party shall
be reimbursed by the Indemnifying Party for reasonable additional legal
expenses, out-of-pocket and allocable share of employee compensation incurred in
connection with such participation for any employee whose participation is so
requested. The foregoing notwithstanding, if the Indemnifying Party fails
diligently to defend any such matter to which the Indemnified Party is entitled
to indemnification hereunder or if the claim involves injunctive or equitable
relief or involves the possibility of criminal penalties, the Indemnified Party
may undertake such defense through counsel of its choice and at the Indemnifying
Party's expense. In each case where the Indemnifying Party is obligated to pay
the costs and expenses of the Indemnified Party, the Indemnifying Party shall
pay the costs and expenses of the Indemnified Party as such costs and expenses
are incurred. If the Indemnifying Party desires to accept a final and complete
settlement of any such Third Person claim and the Indemnified Party refuses to
consent to such settlement, then the Indemnifying Party's liability under this
Section with respect to such Third Person claim shall be limited to the amount
so offered in settlement by said Third Person and the Indemnified Party shall
reimburse the Indemnifying Party for any additional costs of defense which it
subsequently incurs with respect to such claim.

               SECTION 8.5 LIMITATION ON LIABILITY. The indemnification
obligations set forth in this Agreement shall apply only after the aggregate
amount of such obligations exceed $25,000, at which time the indemnification
obligations shall be effective as to all amounts, including the initial $25,000
and shall in no event exceed a maximum of the payments made pursuant to Article
2 hereof.

               SECTION 8.6 SURVIVAL OF INDEMNIFICATION. The indemnification
obligations of the parties contained herein shall survive until July 1, 2001.

             ARTICLE 9. FEDERAL SECURITIES ACT RESTRICTIONS ON STOCK

               SECTION 9.1 REGISTERED STOCK. Parent represents and warrants to
Seller and Seller acknowledges that all of the shares of Parent Stock to be
delivered to Seller pursuant to this Agreement will be registered under the
Securities Act of 1933, as amended (the "Act") prior to delivery to Seller.

               SECTION 9.2  GENERAL LEGEND.  All Parent Stock shall bear
the following legend:

        THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE PROVISIONS
        OF RULE 145(D) PROMULGATED UNDER THE SECURITIES ACT OF 1933, AND MAY NOT
        BE TRANSFERRED OR DISPOSED OF BY THE HOLDER WITHOUT COMPLIANCE WITH SAID
        RULE.

                                      -20-
<PAGE>
               SECTION 9.3 COMPLIANCE WITH LAW. Seller covenants, warrants and
represents that none of the shares of Parent Stock will be offered, sold,
assigned, pledged, hypothecated, transferred or otherwise disposed of except in
full compliance with the Act and the rules and regulations promulgated
thereunder. Further, no Stockholder has any current plan or intention to seller,
exchange or otherwise dispose of any of the Parent Stock following the Closing.

                               ARTICLE 10. GENERAL

               SECTION 10.1 FURTHER ASSURANCE. From time to time after the
Closing, Seller and Stockholders will, without further consideration, execute
and deliver such other instruments of conveyance and transfer, and take such
other action as Buyer reasonably may request to more effectively convey and
transfer to and vest in Buyer and to put Buyer in possession of the Assets to be
transferred hereunder, and in the case of contracts and rights, if any, which
cannot be transferred effectively without the consents of third parties, to
endeavor to obtain such consents promptly, and if any be unobtainable, to use
their best efforts to provide Buyer with the benefits thereof in some other
manner. Seller and Stockholders will cooperate and use their best efforts to
have the present officers, directors and employees of Seller cooperate with
Buyer on and after the Closing in furnishing information, evidence, testimony
and other assistance in connection with any actions, proceedings, arrangements
or disputes of any nature with respect to matters pertaining to all periods
prior to the Closing.

               SECTION 10.2 JOINT AND SEVERAL OBLIGATIONS. All representations,
warranties and agreements of Seller or Stockholders under this Agreement, the
Schedules and the transactions contemplated hereby shall be joint and several.

               SECTION 10.3 WAIVER. Except as otherwise provided herein, no
delay of or omission in the exercise of any right, power or remedy accruing to
any party as a result of any breach or default by any other party under this
Agreement shall impair any such right, power or remedy, nor shall it be
construed as a waiver of or acquiescence in any such breach or default, or of or
in any similar breach or default occurring later; not shall any waiver of any
single breach or default be deemed a waiver of any other breach of default
occurring before or after that waiver.

               SECTION 10.4 TIME OF THE ESSENCE. Time is of the essence of this
Agreement.

               SECTION 10.5 NOTICE. All notices or communications required or

            SECTION 1.3 NON-ASSIGNMENT OF CERTAIN CUSTOMER ACCOUNTS.
Notwithstanding anything to the contrary in this Agreement, to the extent that
the assignment hereunder of any Customer Account shall require the consent of
any third party, neither this Agreement nor any action taken pursuant to its
provisions shall constitute an assignment or an agreement to assign if such
assignment or attempted assignment would constitute a breach thereof or result
in the loss or diminution thereof; provided, however, that in each such case,
Seller shall use its best efforts to obtain the consent of such other party to
such assignment to Buyer. If such consent is not obtained, Seller shall
cooperate with Buyer in any reasonable arrangement designed to provide for Buyer
the benefits under any such Customer Account, including, without limitation, an
adjustment of the purchase price set forth in Section 2.1 hereof and enforcement
for the account and benefit of Buyer, of any and all rights of Seller against
any other person arising out of the breach or cancellation of any such Customer
Account by such other person, or otherwise. Attached hereto as Schedule 1.3 is a
list of all Customer Accounts requiring consent to their assignment.

            SECTION 1.4 SELLER ACCOUNTS RECEIVABLE. (a) Buyer shall have no
liability or obligation whatsoever to Seller in connection with the Accounts
Receivable and Buyer shall not be responsible for collecting the Accounts

payments to Seller as set forth in Section 1.4(b) below. Attached hereto as
Schedule 1.4 is a true and complete list of all Accounts Receivable of Seller as
of February 26, 1998.

            (b) All sums representing Accounts Receivable as set

<PAGE>
      forth on Schedule 1.4 collected by Buyer from the customers set forth on
      Schedule 1.1(d) shall be conclusively presumed to be receipts from the
      collection of the oldest Accounts Receivable of such customer unless the
      customer specifically indicates otherwise in writing. All such sums
      received by Buyer shall be remitted to Seller on a regular basis (but at
      least monthly), together with a reasonably detailed list of the sources
      thereof. Seller shall be entitled to take such action as may be necessary
      in order to collect its unpaid Accounts Receivable; provided, however,
      that Seller agrees not to deliver any such Accounts Receivable to a
      collection agency or institute any litigation related to any Accounts
      Receivable without the prior written consent of Buyer, which consent shall
      not be unreasonably withheld.

            SECTION 1.5 PRORATION OF CASH ON HAND. The parties shall prorate, as
of the close of business on the date of Closing, all cash on hand or on deposit
with Seller consisting of sums paid to Seller pursuant to the advance billing
practice of Seller or otherwise representing a prepayment to Seller of services
to be rendered after the Closing. Seller shall be entitled to all such sums
allocable to services performed on or before the close of business on the date
of Closing and Buyer shall be entitled to all such sums allocable to services to
be performed thereafter.

      International Company, L.P. (the "Terminix Agreement"). Buyer acknowledges
      that the Terminix Agreement grants to Terminix exclusive rights to the
      name "Trapmaster" and to the use of the Trapmaster processes and protocols
      outside of the geographic area described on Exhibit B attached hereto and
      made a part hereof. Buyer, for itself and its officers, employees,
      affiliates, successors and assigns, covenants and agrees with Seller and
      Stockholders not to use the name, processes or protocols of Trapmaster
      outside such geographic area and to indemnify and hold Seller and
      Stockholders harmless against any breach of the foregoing covenant.

            (b) Seller and Stockholders agree that Buyer is not acquiring any
      rights in nor assuming any obligations relating to the Terminix Agreement
      except as set forth in clause (a) above. Seller further covenants and
      agrees with Buyer that Buyer shall have the exclusive right to use the
      Business Name within the geographic area set forth in Exhibit B and that
      Seller has not previously granted such rights to any other party.

            SECTION 4.3 NO DEFENSE OF BUSINESS NAME. Buyer 

                                      -6-
<PAGE>
acknowledges that neither Seller nor any Stockholder will have any obligation to
Buyer to defend or protect the name "Trapmaster" against unauthorized use by
third parties. Notwithstanding the foregoing, Seller and Stockholders each agree
not to use the name Trapmaster within the geographic area set forth in Exhibit
B.

            SECTION 4.4 ACCESS. Seller and Stockholders agree to provide Buyer
with full access to all of the computer software and programs of Seller
containing customer information as Buyer may consider necessary to assist Buyer
with the transition of the operation of the Business. Access will be provided at
all reasonable times and upon reasonable notice from Buyer.

            SECTION 4.5 TRANSITION. Neither Seller nor Stockholders will take
any action that is designed or intended to have the effect of discouraging any
customer or business associate of Seller from maintaining the same business
relationships with Buyer after the Closing that it maintained with Seller before
the Closing. Seller and Stockholders will refer all customer inquiries relating
to the Business to Buyer from and after the Closing. Further, Seller and
Stockholders agree that for a period of 90 days following the date of Closing,
they will, without additional consideration, assist Buyer with the orderly
transition of the operations of the Business from Seller to Buyer. Such
assistance shall include, without limitation, Seller and Stockholders assisting
Buyer to obtain contracts with Seller's current customers, routing transition
activities and development of sufficient information to allow Buyer to compile
accurate customer billings.

            SECTION 4.6 SURVIVAL. Each of the covenants set forth in this
Article 4 shall survive the Closing and the transfer of the Assets.


             ARTICLE 5.  REPRESENTATIONS AND WARRANTIES OF SELLER
                               AND STOCKHOLDERS

            SECTION 5.1 Seller and Stockholders, jointly and severally,
represent and warrant to Buyer that:

            (a)   AUTHORITY.

                  (i) Seller is a corporation duly formed, validly existing and
            in good standing under the laws of the State of Texas. The execution
            and delivery of this Agreement, the consummation of the transactions
            contemplated hereby and the compliance by Seller and Stockholders
            with the terms of this Agreement do not and will not conflict with
            or result in a breach of any terms of, or constitute a default
            under, the articles of incorporation or bylaws of Seller, or any
            instrument 

                                      -7-
<PAGE>
            or other agreement to which Seller or Stockholders are a party or by
            which Seller or Stockholders are bound. This Agreement constitutes a
            valid obligation of Seller and Stockholders enforceable against
            Seller and Stockholders in accordance with its terms except as
            limited by bankruptcy, insolvency, reorganization or other such laws
            concerning the rights of creditors.

                  (ii) Stockholders are each competent, under no duress or legal
            restraint, and have all necessary authority to enter into this
            Agreement, perform their obligations hereunder and consummate the
            transactions contemplated hereby.

                  (iii) All of the issued and outstanding shares of Seller are
            owned of record and beneficially by Stockholders, free and clear of
            all liens, security interests and encumbrances whatsoever.

            (b) COMPLIANCE WITH LAW. Neither Seller nor any of the Stockholders
      is in default under any applicable federal, state or local laws, statutes,
      ordinances, permits, licenses, orders, approvals, variances, rules or
      regulations or judicial or administrative decisions ("Applicable Laws")
      which would have an adverse effect upon the Assets or the Business. Seller
      has been granted all licenses, permits, consents, authorizations and
      approvals from federal, state and local government regulatory bodies
      necessary or desirable to carry on the Business, all of which are
      currently in full force and effect. Each of the Assets complies in all
      respects with all federal, state and local laws, statutes, ordinances,
      permits, licenses, approvals, rules and regulations applicable thereto.

            (c) EQUIPMENT. Listed on Schedule 1.1(a) hereto is a complete and
      accurate list of all Equipment used or for use in connection with the
      Business. Each piece of Equipment is in good working order and repair.

            (d) ROLLING STOCK. Listed on Schedule 1.1(b) hereto is a complete
      and accurate list of all Rolling Stock. Each motor vehicle, attachment,
      accessory and piece of materials handling equipment comprising the Rolling
      Stock is in good working order and repair.

            (e) CUSTOMER ACCOUNTS. Listed on Schedule 1.1(d) hereto is a
      complete and accurate list of the Customer Accounts as of the date hereof.
      Except as set forth on Schedule 1.3, all Customer Accounts are (and will
      be immediately following the Closing) in full force and effect and are
      valid, binding and enforceable against the respective parties thereto in
      accordance with their respective 

                                      -8-
<PAGE>
      provisions, and Seller is not in default in, nor has there occurred an
      event or condition (including Seller's execution and delivery of or
      performance under this Agreement) which with the passage of time or the
      giving of notice (or both) would constitute a default, with regard to the
      payment or performance of any obligation under any Customer Account; no
      claim of such a default has been asserted and there is no reasonable basis
      upon which such a claim could validly be made. Neither Seller nor
      Stockholders has received any notice that any person intends or desires to
      modify, waive, amend, rescind, release, cancel or terminate any Customer
      Account. By virtue of the grant, conveyance, sale, transfer and assignment
      of the Customer Accounts by Seller to Buyer hereunder, Buyer shall own and
      hold all right, title and interest of Seller in and to the Customer
      Accounts, without the consent or approval of any other person or entity.

            (f) TITLE TO THE PERSONAL PROPERTY. Seller has good and marketable
      title to all of the Assets constituting personal property, free and clear
      of all liens, encumbrances, security interests, equities or restrictions
      whatsoever, except the Assumed Leases and, by virtue of the grant,
      conveyance, sale, transfer, and assignment of the Assets hereunder, Buyer
      shall receive good and marketable title to all of the Assets constituting
      personal property, free and clear of all liens, lease payments (including
      lease-end buy-out payments), encumbrances, security interests, equities or
      restrictions whatsoever, except the Assumed Leases. The Assets include all
      of the permits, licenses, franchises, consents and other approvals
      necessary or desirable to conduct the Business.

            (g) TITLE TO REAL PROPERTY. Seller currently leases property located
      at 3507 Sun Belt Drive North, San Antonio, Texas (the "Land") and has
      never owned, leased or otherwise occupied, had an interest in or operated
      any real property other than the Land. Except as set forth on Schedule
      5.1(g):

                  (i) The Land is, and at all times during operation of the
            Business has been, fully licensed, permitted and authorized for the
            operation of the Business under all Applicable Laws relating to the
            protection of the environment, the Land and the conduct of the
            Business thereon (including, without limitation, all zoning
            restrictions and land use requirements).

                  (ii) Neither Seller, Stockholder nor the Land now is or ever
            has been involved in any litigation or administrative proceeding
            seeking to impose fines, penalties or other liabilities or seeking
            injunctive relief for violation of any Applicable Laws relating to
            the environment.

                                      -9-
<PAGE>
            (h) LITIGATION. Except as set forth on Schedule 5.1(h) hereof, there
      is no claim, litigation, action, suit or proceeding, administrative or
      judicial, pending or threatened against Seller or Stockholders, or
      involving the Assets or the Business, at law or in equity, before any
      federal, state or local court or regulatory agency, or other governmental
      authority. Neither Seller nor Stockholders has received any notice of any
      of the above and no facts or circumstances exist which would, with the
      passage of time or giving of notice (or both), give rise to any of the
      above.

            (i) EMPLOYEES. Attached as Schedule 5.1(i) hereof is a complete list
      of all employees of Seller and their respective rates of compensation
      (including a breakdown of the portion thereof attributable to salary,
      bonus and other compensation, respectively) as of the date of Closing.
      Each employee is an employee at will and there are no collective
      bargaining agreements affecting any employee of Seller. Buyer shall not be
      obligated to hire any of Seller's employees.

            (j) EMPLOYEE RELATIONS AND BENEFIT PLANS. Set forth on Schedule
      5.1(j) is an accurate and complete list of all agreements of any kind
      between Seller and its employees or group of employees, including, without
      limitation, employment agreements, collective bargaining agreements and
      benefit plans. Buyer shall not, by the execution and delivery of this
      Agreement or otherwise, become obligated to or assume any liabilities or
      contractual obligations with respect to any employee of Seller or
      otherwise become liable for or obligated in any manner (contractual or
      otherwise) to any employee of Seller, including, without limiting the
      generality of the foregoing, any liability or obligation pursuant to any
      collective bargaining agreement, employment agreement, or pension, profit
      sharing or other employee benefit plan (within the meaning of Section 3(3)
      of the Employment Retirement Income Security Act of 1974, as amended) or
      any other fringe benefit program maintained by Seller or to which Seller
      contributes or any liability for the withdrawal or partial withdrawal from
      or termination of any such plan or program by Seller.

            (k) FINANCIAL STATEMENTS. Seller has delivered to Buyer copies of
      Seller's balance sheet as of December 31, 1997 (the "Balance Sheet Date"),
      and a statement of income, cash flow and retained earnings for the period
      then ended (the "Financial Statements"). The Financial Statements
      (including any footnotes thereto) have been prepared in accordance with
      generally accepted accounting principles ("GAAP"), applied on a consistent
      basis throughout the periods indicated. The Financial Statements
      (including all 

                                      -10-
<PAGE>
      footnotes thereto) are true, complete and correct and present fairly the
      financial condition and the results of the operations of Seller for the
      period indicated thereon. All reserves for contingent risks have been
      estimated in accordance with GAAP and are appropriate and sufficient to
      cover all costs reasonably expected to be incurred from such risks. The
      Financial Statements are consistent with the books and records of Seller
      (which books and records are correct and complete).

            (l) TAXES. No federal, state, local or other tax returns or reports
      filed by Seller (whether filed prior to, on or after the date hereof) with
      respect to the Business or the Assets will result in any taxes,
      assessments, fees or other governmental charges upon the Assets or Buyer,
      whether as a transferee of the Assets or otherwise. All federal, state and
      local taxes due and payable with respect to the Business or the Assets
      have been paid, including, without limiting the generality of the
      foregoing, all federal, state and local income, sales, use, franchise,
      excise and property taxes.

            (m) HAZARDOUS MATERIALS. Neither Seller nor any of the Stockholders
      has ever generated, transported, stored, handled, recycled, reclaimed,
      disposed of, or contracted for the disposal of, hazardous materials,
      hazardous wastes, hazardous substances, toxic wastes or substances,
      infectious or medical waste, radioactive waste or sewage sludges as those
      terms are defined by the Resource Conservation and Recovery Act of 1976;
      the Comprehensive Environmental Response, Compensation and Liability Act
      of 1980 ("CERCLA"); the Atomic Energy Act of 1954; the Toxic Substances
      Control Act; the Occupational Health and Safety Act; any comparable or
      similar Texas statute; or the rules and regulations promulgated under any
      of the foregoing, as each of the foregoing may have been from time to time
      amended (collectively, "Hazardous Materials"). Seller has never owned,
      operated, had an interest in, engaged in and/or leased a waste transfer,
      recycling, treatment, storage or disposal facility, business or activity
      other than the Business. Seller has obtained and maintained all necessary
      trip tickets, signed by the applicable waste generators, and other records
      demonstrating the nature of the waste transported in connection with the
      Business. No employee, contractor or agent of Seller has, in the course
      and scope of employment with Seller, been harmed by exposure to Hazardous
      Materials. Seller has no direct or contingent liability or obligation for
      or in connection with any claimed release, discharge or leak of any
      substance onto the Land or into the environment. Further, no portion of
      the Land is listed on the CERCLA list or the National Priorities List of
      Hazardous Waste Sites or any similar list maintained by the State of
      Texas. Attached 

                                      -11-
<PAGE>
      hereto as Schedule 5.1(m) is a complete list of the names and addresses of
      all disposal sites at any time now or in the past utilized by Seller, none
      of which sites is listed on the CERCLA list or the National Priorities
      List of Hazardous Waste Sites or any comparable Texas list. Neither Seller
      nor any of the Stockholders is listed as a potentially responsible party
      under CERCLA or any comparable or similar Texas statute; neither Seller
      nor any of the Stockholders has received any notice of such a listing; and
      neither Seller nor Stockholders knows of any facts or circumstances which
      could give rise to such a listing.

            (n) GOVERNMENT NOTICES. Seller has delivered to Buyer, a description
      and copies, as of the date of this Agreement, of all notifications, filed
      or submitted, or required to be filed or submitted, to governmental
      agencies and of all material notifications from such governmental agencies
      relating to Seller and the Assets or relating to the discharge or release
      of materials into the environment or otherwise relating to the protection
      of the public health or the environment.

            (o) ABSENCE OF PRICE RENEGOTIATION CONTRACTS. Seller is not now nor
      has ever been a party to any governmental contracts subject to price
      redetermination or renegotiation.

            (p) GROSS REVENUES. The gross revenues generated by the Business for
      the 12-month period immediately preceding the month in which the Closing
      occurs were $______________.

            (q) UNDERGROUND STORAGE TANKS. Except for the Land, Seller has never
      owned, leased or operated any real estate having any underground storage
      tanks containing petroleum products or wastes or other hazardous
      substances regulated by 40 CFR 280 and/or other applicable federal, state
      or local laws, rules and regulations and requirements. Set forth on
      Schedule 5.1(q) is a list of all above and below ground tanks located on
      the Land, each of which are being used and maintained in accordance with
      Applicable Laws.

            (r) COMPLETENESS OF DISCLOSURE. This Agreement and the Schedules
      hereto and all other documents and information furnished to Buyer and its
      representatives pursuant hereto do not and will not include any untrue
      statement of a material fact or omit to state a material fact necessary to
      make the statements therein not misleading. If Seller or Stockholders
      become aware of any fact or circumstance which would change a
      representation or warranty of Seller or Stockholders in this Agreement,
      the party with such knowledge shall immediately give notice of such fact
      or circumstance to Buyer. However, such notification shall not relieve
      Seller or Stockholders of their obligations under this Agreement, and at
      the sole 

                                      -12-
<PAGE>
      option of Buyer, the truth and accuracy of any and all warranties and
      representations of Seller and Stockholders at the date of this Agreement
      shall be a precondition to the consummation of this transaction.

            SECTION 5.2 SURVIVAL. Each of the representations and warranties set
forth in this Article 5 shall survive the Closing and the transfer of the
Assets.


        ARTICLE 6.  REPRESENTATIONS AND WARRANTIES OF BUYER AND PARENT

            SECTION 6.1 Buyer and Parent represent and warrant to Seller and
Stockholders that:

            (a) CORPORATE ORGANIZATION. Buyer is a corporation duly organized,
      validly existing and in good standing under the laws of the State of
      Texas. Parent is a corporation duly organized, validly existing and in
      good standing under the laws of the State of Delaware.

            (b) AUTHORIZATION. Buyer and Parent each have all requisite
      corporate power and corporate authority to enter into this Agreement,
      perform its respective obligations hereunder and consummate the
      transactions contemplated hereby. The execution and delivery of this
      Agreement, the consummation of the transactions contemplated hereby and
      the compliance by Buyer and Parent with the terms of this Agreement do not
      and will not conflict with or result in a breach of any terms of, or
      constitute a default under, Buyer's Articles of Incorporation or Bylaws or
      any other agreement or instrument to which Buyer or Parent is a party or
      by which Buyer or Parent is bound. All necessary corporate action has been
      taken by Buyer and Parent with respect to the execution and delivery of
      this Agreement, and this Agreement constitutes a valid obligation of Buyer
      and Parent enforceable in accordance with its terms except as limited by
      bankruptcy, insolvency, reorganization or other such laws concerning the
      rights of creditors.

            (c) PARENT STOCK. The Parent Stock to be delivered to Seller in
      connection with this Agreement, when delivered in accordance with the
      terms of this Agreement, will constitute valid and legally issued shares,
      fully paid and nonassessable and will be registered and free from any
      restriction on transfer other than restrictions imposed by the Securities
      Act of 1993, as amended, or the regulations promulgated thereunder.

            SECTION 6.2 SURVIVAL. Each of the representations and warranties set
forth in this Article 6 shall survive the Closing and the transfer of the
Assets.

                                      -13-
<PAGE>
                          ARTICLE 7.  NONCOMPETITION

            SECTION 7.1 NONCOMPETITION COVENANTS. Seller and each of the
Stockholders, jointly and severally, agree that for a period of five years
following the date of Closing, none of them shall directly or indirectly,
through a subsidiary or affiliate, without the prior express written consent of
Buyer:

            (i) engage, whether as a corporation on its own account, or as an
      officer, director, shareholder, owner, partner, joint venturer, investor,
      agent, or in a managerial capacity, whether as an employee, independent
      contractor, consultant or advisor, or as a sales representative, in the
      business of: siting, developing, constructing, permitting or operating a
      facility for the processing, treatment or disposal of non-hazardous liquid
      waste (including, without limitation, waste oil, waste water, grease trap
      waste, grit trap waste and oil contaminated water); siting, developing,
      constructing, permitting or operating a facility for the processing,
      treatment and disposal of non-hazardous oilfield waste (including, without
      limitation, chlorides, heavy metals, cuttings, contaminated soils,
      drilling fluids and pit sludges); and transportation or collection of any
      such materials, in each case within a radius of 100 air miles of San
      Antonio, Texas (the "Territory");

            (ii) call upon any person who is, at that time, within the
      Territory, an employee of Buyer in a managerial capacity for the purpose
      or with the intent of enticing such employee away from or out of the
      employ of Buyer;

            (iii) call upon any person or entity which is, at that time, or
      which has been, within one year prior to that time, a customer of Seller
      or Buyer, as the case may be, within the Territory for the purpose of:
      siting, developing, constructing, permitting or operating a facility for
      the processing, treatment or disposal of non-hazardous liquid waste
      (including, without limitation, waste oil, waste water, grease trap waste,
      grit trap waste and oil contaminated water); siting, developing,
      constructing, permitting or operating a facility for the processing,
      treatment and disposal of non-hazardous oilfield waste (including, without
      limitation, chlorides, heavy metals, cuttings, contaminated soils,
      drilling fluids and pit sludges); and transportation or collection of any
      such materials, in each case within the Territory;

            (iv) call upon any prospective acquisition candidate, on their own
      behalf or on behalf of any competitor, which candidate was either called
      upon by Seller or Stockholders or 

                                      -14-
<PAGE>
      for which Seller or Stockholders made an acquisition analysis for Seller
      or Buyer;

            (v) disclose the identity of Buyer's customers, whether in existence
      or proposed, to any person, firm, partnership, corporation or business for
      any reason or purpose whatsoever; or

            (vi) promote or assist, financially or otherwise (including, without
      limitation, lending, guaranteeing loans or otherwise providing financial
      assurance in any way), any person, firm, partnership, corporation or other
      entity whatsoever to do any of the above.

            Notwithstanding the above, the foregoing covenant shall not be
deemed to prohibit Seller or Stockholders from: (A) acquiring as an investment
not more than one percent of the capital stock of a competing business, whose
stock is traded on a national securities exchange or over-the-counter; (B)
continuing to operate the portion of its drain treatment business that utilizes
on site organic chemicals as the treatment process; or (C) taking such actions
necessary to comply with the terms and conditions of the Terminix Agreement.

            SECTION 7.2 INJUNCTIVE RELIEF. Because of the difficulty of
measuring economic losses to Buyer as a result of the breach of the foregoing
covenant, and because of the immediate and irreparable damage that would be
caused to Buyer for which it would have no other adequate remedy, Seller and
Stockholders agree that, in the event of breach by any of them of the foregoing
covenant, the covenant may be enforced by Buyer by, without limitation,
injunctions and restraining orders.

            SECTION 7.3 REASONABLENESS OF COVENANTS. It is agreed by the parties
that the foregoing covenants in this Section 7 impose a reasonable restraint on
Seller and Stockholders in light of the activities and business of the Buyer on
the date of the execution of this Agreement and the future plans of the Buyer.

            SECTION 7.4 SEVERABILITY OF COVENANTS. The covenants in this Section
7 are severable and separate, and the unenforceability of any specific covenant
shall not affect the provisions of any other covenant. Moreover, in the event
any court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

            SECTION 7.5 INDEPENDENT COVENANTS. All of the covenants in this
Section 7 shall be construed as an agreement independent of any other provision
of this Agreement, and the 

                                      -15-
<PAGE>
existence of any claim or clause of action of Seller or Stockholders against
Buyer, whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by Buyer of such covenants. It is specifically agreed
that the duration of the noncompetition covenants stated above shall be computed
by excluding from such computation any time during which Seller or Stockholders
is in violation of any provision of this Section 7 and any time during which
there is pending in any court of competent jurisdiction any action (including
any appeal from any judgment) brought by any person, whether or not a party to

            SECTION 8.4 PROCEDURE FOR INDEMNIFICATION. Promptly after a party
hereto (hereinafter the "Indemnified Party") has received notice of or has
knowledge of any claim by a person not a party to this Agreement ("Third
Person") or the commencement of any action or proceeding by a Third Person, the
Indemnified Party shall, as a condition precedent to a claim with respect
thereto being made against any party obligated to provide indemnification
pursuant to this Agreement (hereinafter the "Indemnifying Party"), give the
Indemnifying Party written notice of such claim or the commencement of such
action or proceeding (the "Notice"). The Notice shall state the nature and the
basis of such claim and a reasonable estimate of the amount thereof. The
Indemnifying Party, after receipt of the Notice, shall defend and settle, at its
own expense and by its own counsel, each such matter so long as the Indemnifying
Party pursues the same diligently and in good faith and the claim does not
involve injunctive or equitable relief or involve the possibility of criminal
penalties. The Indemnified Party shall cooperate with the Indemnifying Party and
its counsel in the defense thereof and in any settlement thereof. Such
cooperation shall include, but shall not be limited to, furnishing the
Indemnifying Party with any books, records or information reasonably requested
by the Indemnifying Party that are in the Indemnified Party's possession or
control. Notwithstanding the foregoing, the Indemnified Party shall have the
right to participate in any matter through counsel of its own choosing at its
own expense, provided that the Indemnifying Party's counsel shall always be lead
counsel and shall determine all litigation and settlement steps, strategy and
the like. After the Indemnifying Party has received the Notice, the Indemnifying
Party shall not be liable for any additional legal expenses incurred by the
Indemnified Party in connection with any defense or settlement of such asserted
liability, except to the extent such participation is requested by the
Indemnifying Party, in which event the Indemnified Party shall be reimbursed by
the Indemnifying Party for reasonable additional legal expenses, out-of-pocket
and allocable share of employee compensation incurred in connection with such
participation for any employee whose participation is so requested. The
foregoing notwithstanding, if the Indemnifying Party fails diligently to defend
any such matter to which the Indemnified Party is entitled to indemnification
hereunder or if the claim involves injunctive or equitable relief or involves
the possibility of criminal penalties, the Indemnified Party may undertake such
defense through counsel of its choice and at the Indemnifying Party's expense.
In each case where the Indemnifying Party is obligated to pay the costs and
expenses of the Indemnified Party, the Indemnifying Party shall pay the costs
and expenses of the Indemnified Party as such costs and expenses are incurred.
If the Indemnifying Party desires to accept a final and complete settlement of
any such Third Person claim and the Indemnified Party refuses to consent to such
settlement, then the Indemnifying Party's liability under this Section with
respect to 

                                      -19-
<PAGE>
such Third Person claim shall be limited to the amount so offered in settlement
by said Third Person and the Indemnified Party shall reimburse the Indemnifying
Party for any additional costs of defense which it subsequently incurs with
respect to such claim.


                              ARTICLE 9.  GENERAL

            SECTION 9.1 FURTHER ASSURANCE. From time to time after the Closing,
Seller and Stockholders will, without further consideration, execute and deliver
such other instruments of conveyance and transfer, and take such other action as
Buyer reasonably may request to more effectively convey and transfer to and vest
in Buyer and to put Buyer in possession of the Assets to be transferred
hereunder, and in the case of contracts and rights, if any, which cannot be
transferred effectively without the consents of third parties, to endeavor to
obtain such consents promptly, and if any be unobtainable, to use their best
efforts to provide Buyer with the benefits thereof in some other manner. Seller
and Stockholders will cooperate and use their best efforts to have the present
officers, directors and employees of Seller cooperate with Buyer on and after
the Closing in furnishing information, evidence, testimony and other assistance
in connection with any actions, proceedings, arrangements or disputes of any
nature with respect to matters pertaining to all periods prior to the Closing.

shall impair any such right, power or remedy, nor shall it be construed as a
waiver of or acquiescence in any such breach or default, or of or in any similar
breach or default occurring later; not shall any waiver of any single breach or
default be deemed a waiver of any other breach of default occurring before or
after that waiver.

Exterminating Service"; (g) all assets and obligations related to the Excluded
Business; and (h) any items listed on Schedule 1.2.

            SECTION 1.3 NON-ASSIGNMENT OF CERTAIN CUSTOMER ACCOUNTS.
Notwithstanding anything to the contrary in this Agreement, to the extent that
the assignment hereunder of any Customer Account shall require the consent of
any third party, neither this Agreement nor any action taken pursuant to its
provisions shall constitute an assignment or an agreement to assign if such
assignment or attempted assignment would constitute a breach thereof or result
in the loss or diminution thereof; provided, however, that in each such case,
Seller shall use its best efforts to obtain the consent of such other party to
such assignment to Buyer. If such consent is not obtained, Seller shall
cooperate with Buyer in any reasonable arrangement designed to provide for Buyer
the benefits under any such Customer Account, including, without limitation, an
adjustment of the purchase price set forth in Section 2.1 hereof and enforcement
for the account and benefit of Buyer, of any and all rights of Seller against
any other person arising out of the breach or cancellation of any such Customer
Account by such other person, or otherwise. Attached hereto as Schedule 1.3 is a
list of all Customer Accounts requiring consent to their assignment.

            SECTION 1.4 SELLER ACCOUNTS RECEIVABLE. (a) Buyer shall have no
      liability or obligation whatsoever to Seller in connection with the
      Accounts Receivable and Buyer shall not be responsible for collecting the
      Accounts Receivable. However, if Buyer receives any payments which are
      designated by the customer as being toward such Accounts Receivable, then
      Buyer shall forward such payments to Seller as set forth in Section 1.4(b)
      below. Attached hereto as Schedule 1.4 is a true and complete list of all
      Accounts Receivable of Seller as of __________, 1998.

            (b) All sums representing Accounts Receivable as set forth on
      Schedule 1.4 collected by Buyer from the customers set forth on Schedule
      1.1(d) shall be conclusively presumed to be receipts from the collection
      of the oldest Accounts Receivable of such customer unless the customer
      specifically indicates otherwise in writing. All such sums received by
      Buyer shall be remitted to Seller on a regular basis (but at least
      monthly), together with an itemized list of the sources thereof. Seller
      shall be entitled to take such action as may be necessary in order to
      collect its unpaid Accounts Receivable; provided, however, that Seller
      agrees not to deliver any such Accounts Receivable to a collection agency
      or institute any litigation related to any Accounts Receivable without the
      prior written consent of Buyer, which consent shall not be unreasonably
      withheld.

            SECTION 1.5 PRORATION OF CASH ON HAND. The parties 

                                      -3-

hand or on deposit with Seller consisting of sums paid to Seller pursuant to the
advance billing practice of Seller or otherwise representing a prepayment to
Seller of services to be rendered after the Closing in connection with the
Business (but not the Excluded Business). Seller shall be entitled to all such
sums allocable to services performed on or before the close of business on the
date of Closing in connection with the Business (but not the Excluded Business)
and Buyer shall be entitled to all such sums allocable to services to be
performed thereafter in connection with the Business (but not the Excluded
Business).

             ARTICLE 5.  REPRESENTATIONS AND WARRANTIES OF SELLER
                               AND STOCKHOLDER

            SECTION 5.1 Seller and Stockholder, jointly and severally, represent
and warrant to Buyer that:

            (a)   AUTHORITY.

                  (i) Seller is a corporation duly formed, validly existing and
            in good standing under the laws of the State of Texas. The execution
            and delivery of this Agreement, the consummation of the transactions
            contemplated hereby and the compliance by Seller and Stockholder
            with the terms of this Agreement do not and will not conflict with
            or result in a breach of any terms of, or constitute a default
            under, the articles of incorporation or bylaws of Seller, or any
            instrument or other agreement to which Seller or Stockholder are a
            party or by which Seller or Stockholder are bound. This Agreement
            constitutes a valid obligation of Seller and Stockholder enforceable
            against Seller and Stockholder in accordance with its terms except
            as limited by bankruptcy, insolvency, reorganization or other such
            laws concerning the rights of creditors.

                  (ii) Stockholder is competent, under no duress or legal
            restraint, and has all necessary authority to enter into this
            Agreement, perform his obligations hereunder and consummate the
            transactions contemplated hereby.

                  (iii) A majority of the issued and outstanding shares of
            Seller are owned of record and beneficially by Stockholder, free and
            clear of all liens, security interests and encumbrances whatsoever.

                                      -6-
<PAGE>
            (b) COMPLIANCE WITH LAW. Neither Seller nor Stockholder is in
      default under any applicable federal, state or local laws, statutes,
      ordinances, permits, licenses, orders, approvals, variances, rules or
      regulations or judicial or administrative decisions ("Applicable Laws")
      which would have an adverse effect upon the Assets or the Business. Seller
      has been granted all licenses, permits, consents, authorizations and
      approvals from federal, state and local government regulatory bodies
      necessary or desirable to carry on the Business, all of which are
      currently in full force and effect. Each of the Assets complies in all
      respects with all federal, state and local laws, statutes, ordinances,
      permits, licenses, approvals, rules and regulations applicable thereto.

            (c) EQUIPMENT. Listed on Schedule 1.1(a) hereto is a complete and
      accurate list of all Equipment used or for use in connection with the
      Business. Each piece of Equipment is in good working order and repair.

            (d) ROLLING STOCK. Listed on Schedule 1.1(b) hereto is a complete
      and accurate list of all Rolling Stock. Each motor vehicle, attachment,
      accessory and piece of materials handling equipment comprising the Rolling
      Stock is in good working order and repair.

            (e) CUSTOMER ACCOUNTS. Listed on Schedule 1.1(d) hereto is a
      complete and accurate list of the Customer Accounts as of the date hereof.
      Except as set forth on Schedule 1.3, all Customer Accounts are (and will
      be immediately following the Closing) in full force and effect and are
      valid, binding and enforceable against the respective parties thereto in
      accordance with their respective provisions, and Seller is not in default
      in, nor has there occurred an event or condition (including Seller's
      execution and delivery of or performance under this Agreement) which with
      the passage of time or the giving of notice (or both) would constitute a
      default, with regard to the payment or performance of any obligation under
      any Customer Account; no claim of such a default has been asserted and
      there is no reasonable basis upon which such a claim could validly be
      made. Neither Seller nor Stockholder has received any notice that any
      person intends or desires to modify, waive, amend, rescind, release,
      cancel or terminate any Customer Account. By virtue of the grant,
      conveyance, sale, transfer and assignment of the Customer Accounts by
      Seller to Buyer hereunder, Buyer shall own and hold all right, title and
      interest of Seller in and to the Customer Accounts, without the consent or
      approval of any other person or entity.

            (f) TITLE TO THE PERSONAL PROPERTY. Seller has good 

                                      -7-
<PAGE>
      and marketable title to all of the Assets constituting personal property,
      free and clear of all liens, encumbrances, security interests, equities or
      restrictions whatsoever and, by virtue of the grant, conveyance, sale,
      transfer, and assignment of the Assets hereunder, Buyer shall receive good
      and marketable title to all of the Assets constituting personal property,
      free and clear of all liens, lease payments (including lease-end buy-out
      payments), encumbrances, security interests, equities or restrictions
      whatsoever. The Assets include all of the permits, licenses, franchises,
      consents and other approvals necessary or desirable to conduct the
      Business.

            (g) TITLE TO REAL PROPERTY. Seller currently owns property located
      at 8411 N. 1H35 Austin, Texas 78753 (the "Land") and has never owned,
      leased or otherwise occupied, had an interest in or operated any real
      property other than the Land. Except as set forth on Schedule 5.1(g):

                  (i) The Land is, and at all times during operation of the
            Business has been, fully licensed, permitted and authorized for the
            operation of the Business under all Applicable Laws relating to the
            protection of the environment, the Land and the conduct of the
            Business thereon (including, without limitation, all zoning
            restrictions and land use requirements).

                  (ii) Neither Seller, Stockholder nor the Land now is or ever
            has been involved in any litigation or administrative proceeding
            seeking to impose fines, penalties or other liabilities or seeking
            injunctive relief for violation of any Applicable Laws relating to
            the environment.

            (h) LITIGATION. Except as set forth on Schedule 5.1(h) hereof, there
      is no claim, litigation, action, suit or proceeding, administrative or
      judicial, pending or threatened against Seller or Stockholder, or
      involving the Assets or the Business, at law or in equity, before any
      federal, state or local court or regulatory agency, or other governmental
      authority. Neither Seller nor Stockholder has received any notice of any
      of the above and no facts or circumstances exist which would, with the
      passage of time or giving of notice (or both), give rise to any of the
      above.

                                      -8-
<PAGE>
            (i) EMPLOYEES. Attached as Schedule 5.1(i) hereof is a complete list
      of all employees of Seller and their respective rates of compensation
      (including a breakdown of the portion thereof attributable to salary,
      bonus and other compensation, respectively) as of the date of Closing.
      Each employee is an employee at will and there are no collective
      bargaining agreements affecting any employee of Seller. Buyer shall not be
      obligated to hire any of Seller's employees.

            (j) EMPLOYEE RELATIONS AND BENEFIT PLANS. Set forth on Schedule
      5.1(j) is an accurate and complete list of all agreements of any kind
      between Seller and its employees or group of employees, including, without
      limitation, employment agreements, collective bargaining agreements and
      benefit plans. Buyer shall not, by the execution and delivery of this
      Agreement or otherwise, become obligated to or assume any liabilities or
      contractual obligations with respect to any employee of Seller or
      otherwise become liable for or obligated in any manner (contractual or
      otherwise) to any employee of Seller, including, without limiting the
      generality of the foregoing, any liability or obligation pursuant to any
      collective bargaining agreement, employment agreement, or pension, profit
      sharing or other employee benefit plan (within the meaning of Section 3(3)
      of the Employment Retirement Income Security Act of 1974, as amended) or
      any other fringe benefit program maintained by Seller or to which Seller
      contributes or any liability for the withdrawal or partial withdrawal from
      or termination of any such plan or program by Seller.

            (k) FINANCIAL STATEMENTS. Seller has delivered to Buyer copies of
      Seller's balance sheet as of December 31, 1997 (the "Balance Sheet Date"),
      and a statement of income, cash flow and retained earnings for the period
      then ended (the "Financial Statements"). The Financial Statements
      (including any footnotes thereto) have been prepared in accordance with
      generally accepted accounting principles ("GAAP"), applied on a consistent
      basis throughout the periods indicated. The Financial Statements
      (including all footnotes thereto) are true, complete and correct and
      present fairly the financial condition and the results of the operations
      of Seller for the period indicated thereon. All reserves for contingent
      risks have been estimated in accordance with GAAP and are appropriate and
      sufficient to cover all costs reasonably expected to be incurred from such
      risks. The Financial Statements are consistent with the books and records
      of Seller (which books and records are correct and complete).

            (l) TAXES. No federal, state, local or other tax returns or reports
      filed by Seller (whether filed prior to, 

                                      -9-
<PAGE>
      on or after the date hereof) with respect to the Business or the Assets
      will result in any taxes, assessments, fees or other governmental charges
      upon the Assets or Buyer, whether as a transferee of the Assets or
      otherwise. All federal, state and local taxes due and payable with respect
      to the Business or the Assets have been paid, including, without limiting
      the generality of the foregoing, all federal, state and local income,
      sales, use, franchise, excise and property taxes.

            (m) HAZARDOUS MATERIALS. Neither Seller nor Stockholder has ever
      generated, transported, stored, handled, recycled, reclaimed, disposed of,
      or contracted for the disposal of, hazardous materials, hazardous wastes,
      hazardous substances, toxic wastes or substances, infectious or medical
      waste, radioactive waste or sewage sludges as those terms are defined by
      the Resource Conservation and Recovery Act of 1976; the Comprehensive
      Environmental Response, Compensation and Liability Act of 1980 ("CERCLA");
      the Atomic Energy Act of 1954; the Toxic Substances Control Act; the
      Occupational Health and Safety Act; any comparable or similar Texas
      statute; or the rules and regulations promulgated under any of the
      foregoing, as each of the foregoing may have been from time to time
      amended (collectively, "Hazardous Materials"). Seller has never owned,
      operated, had an interest in, engaged in and/or leased a waste transfer,
      recycling, treatment, storage or disposal facility, business or activity
      other than the Business. Seller has obtained and maintained all necessary
      trip tickets, signed by the applicable waste generators, and other records
      demonstrating the nature of the waste transported in connection with the
      Business. No employee, contractor or agent of Seller has, in the course
      and scope of employment with Seller, been harmed by exposure to Hazardous
      Materials. Seller has no direct or contingent liability or obligation for
      or in connection with any claimed release, discharge or leak of any
      substance onto the Land or into the environment. Further, no portion of
      the Land is listed on the CERCLA list or the National Priorities List of
      Hazardous Waste Sites or any similar list maintained by the State of
      Texas. Attached hereto as Schedule 5.1(m) is a complete list of the names
      and addresses of all disposal sites at any time now or in the past
      utilized by Seller, none of which sites is listed on the CERCLA list or
      the National Priorities List of Hazardous Waste Sites or any comparable
      Texas list. Neither Seller nor Stockholder is listed as a potentially
      responsible party under CERCLA or any comparable or similar Texas statute;
      neither Seller nor Stockholder has received any notice of such a listing;
      and neither Seller nor Stockholder knows of any facts or circumstances
      which could give rise to such a listing.

            (n) GOVERNMENT NOTICES. Seller has delivered to 

                                      -10-
<PAGE>
      Buyer, a description and copies, as of the date of this Agreement, of all
      notifications, filed or submitted, or required to be filed or submitted,
      to governmental agencies and of all material notifications from such
      governmental agencies relating to Seller and the Assets or relating to the
      discharge or release of materials into the environment or otherwise
      relating to the protection of the public health or the environment.

            (o) ABSENCE OF PRICE RENEGOTIATION CONTRACTS. Seller is not now nor
      has ever been a party to any governmental contracts subject to price
      redetermination or renegotiation.

            (p) GROSS REVENUES. The gross revenues generated by the Business for
      the 12-month period immediately preceding the month in which the Closing
      occurs were $______________.

            (q) UNDERGROUND STORAGE TANKS. Except for the Land, Seller has never
      owned, leased or operated any real estate having any underground storage
      tanks containing petroleum products or wastes or other hazardous
      substances regulated by 40 CFR 280 and/or other applicable federal, state
      or local laws, rules and regulations and requirements. Set forth on
      Schedule 5.1(q) is a list of all above and below ground tanks located on
      the Land, each of which are being used and maintained in accordance with
      Applicable Laws.

            (r) COMPLETENESS OF DISCLOSURE. This Agreement and the Schedules
      hereto and all other documents and information furnished to Buyer and its
      representatives pursuant hereto do not and will not include any untrue
      statement of a material fact or omit to state a material fact necessary to
      make the statements therein not misleading. If Seller or Stockholder
      become aware of any fact or circumstance which would change a
      representation or warranty of Seller or Stockholder in this Agreement, the
      party with such knowledge shall immediately give notice of such fact or
      circumstance to Buyer. However, such notification shall not relieve Seller
      or Stockholder of their obligations under this Agreement, and at the sole
      option of Buyer, the truth and accuracy of any and all warranties and
      representations of Seller and Stockholder at the date of this Agreement
      shall be a precondition to the consummation of this transaction.

            SECTION 5.2 SURVIVAL. Each of the representations and warranties set
forth in this Article 5 shall survive the Closing and the transfer of the
Assets.


        ARTICLE 6.  REPRESENTATIONS AND WARRANTIES OF BUYER AND PARENT

      transactions contemplated hereby. The execution and delivery of this
      Agreement, the consummation of the transactions contemplated hereby and
      the compliance by Buyer and Parent with the terms of this Agreement do not
      and will not conflict with or result in a breach of any terms of, or
      constitute a default under, Buyer's Articles of Incorporation or Bylaws or
      any other agreement or instrument to which Buyer or Parent is a party or
      by which Buyer or Parent is bound. All necessary corporate action has been
      taken by Buyer and Parent with respect to the execution and delivery of
      this Agreement, and this Agreement constitutes a valid obligation of Buyer
      and Parent enforceable in accordance with its terms except as limited by

      rights of creditors.

            (c) PARENT STOCK. The Parent Stock to be delivered to Seller in
      connection with this Agreement, when delivered in accordance with the
      terms of this Agreement, will constitute valid and legally issued shares,
      fully paid and nonassessable and will be registered and free from any
      restriction on transfer other than restrictions imposed by the Securities
      Act of 1993, as amended, or the regulations promulgated thereunder.

            SECTION 6.2 SURVIVAL. Each of the representations and warranties set
forth in this Article 6 shall survive the Closing and the transfer of the
Assets.

affiliate, without the prior express written consent of Buyer:

            (i) engage, whether as a corporation on its own account, or as an
      officer, director, shareholder, owner, partner, joint venturer, investor,
      agent, or in a managerial 

                                      -12-
<PAGE>
      capacity, whether as an employee, independent contractor, consultant or
      advisor, or as a sales representative, in the business of: siting,
      developing, constructing, permitting or operating a facility for the
      processing, treatment or disposal of non-hazardous liquid waste
      (including, without limitation, waste oil, waste water, grease trap waste,
      grit trap waste and oil contaminated water); siting, developing,
      constructing, permitting or operating a facility for the processing,
      treatment and disposal of non-hazardous oilfield waste (including, without
      limitation, chlorides, heavy metals, cuttings, contaminated soils,
      drilling fluids and pit sludges); and transportation or collection of any
      such materials, in each case within a radius of 100 air miles of Austin,
      Texas (the "Territory");

            (ii) call upon any person who is, at that time, within the
      Territory, an employee of Buyer in a managerial capacity for the purpose
      or with the intent of enticing such employee away from or out of the
      employ of Buyer;

            (iii) call upon any person or entity which is, at that time, or
      which has been, within one year prior to that time, a customer of Seller
      or Buyer, as the case may be, within the Territory for the purpose of:
      siting, developing, constructing, permitting or operating a facility for
      the processing, treatment or disposal of non-hazardous liquid waste
      (including, without limitation, waste oil, waste water, grease trap waste,
      grit trap waste and oil contaminated water); siting, developing,
      constructing, permitting or operating a facility for the processing,
      treatment and disposal of non-hazardous oilfield waste (including, without
      limitation, chlorides, heavy metals, cuttings, contaminated soils,
      drilling fluids and pit sludges); and transportation or collection of any
      such materials, in each case within the Territory;

            (iv) call upon any prospective acquisition candidate, on their own
      behalf or on behalf of any competitor, which candidate was either called
      upon by Seller or Stockholder or for which Seller or Stockholder made an
      acquisition analysis for Seller or Buyer;

            (v) disclose the identity of Buyer's customers, whether in existence
      or proposed, to any person, firm, partnership, corporation or business for
      any reason or purpose whatsoever; or

            (vi) promote or assist, financially or otherwise (including, without
      limitation, lending, guaranteeing loans or otherwise providing financial
      assurance in any way), any person, firm, partnership, corporation or other
      entity whatsoever to do any of the above.

                                      -13-
<PAGE>
            Notwithstanding the above, the foregoing covenant shall not be
deemed to prohibit Seller or Stockholder from: (A) acquiring as an investment
not more than one percent of the capital stock of a competing business, whose
stock is traded on a national securities exchange or over-the-counter; or (B)
owning, operating or selling the Excluded Business.

            SECTION 7.2 INJUNCTIVE RELIEF. Because of the difficulty of
measuring economic losses to Buyer as a result of the breach of the foregoing
covenant, and because of the immediate and irreparable damage that would be
caused to Buyer for which it would have no other adequate remedy, Seller and
Stockholder agree that, in the event of breach by any of them of the foregoing
covenant, the covenant may be enforced by Buyer by, without limitation,
injunctions and restraining orders.

            SECTION 7.3 REASONABLENESS OF COVENANTS. It is agreed by the parties
that the foregoing covenants in this Section 7 impose a reasonable restraint on
Seller and Stockholder in light of the activities and business of the Buyer on
the date of the execution of this Agreement and the future plans of the Buyer.

            SECTION 7.4 SEVERABILITY OF COVENANTS. The covenants in this Section
7 are severable and separate, and the unenforceability of any specific covenant
shall not affect the provisions of any other covenant. Moreover, in the event
any court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

            SECTION 7.5 INDEPENDENT COVENANTS. All of the covenants in this
Section 7 shall be construed as an agreement independent of any other provision
of this Agreement, and the existence of any claim or clause of action of Seller
or Stockholder against Buyer, whether predicated on this Agreement or otherwise,
shall not constitute a defense to the enforcement by Buyer of such covenants. It
is specifically agreed that the duration of the noncompetition covenants stated
above shall be computed by excluding from such computation any time during which
Seller or Stockholder is in violation of any provision of this Section 7 and any
time during which there is pending in any court of competent jurisdiction any
action (including any appeal from any judgment) brought by any person, whether
or not a party to this Agreement, in which action Buyer seeks to enforce the
agreements and covenants of Seller or Stockholder or in which any person
contests the validity of such agreements and covenants or their enforceability
or seeks to avoid their performance or enforcement.

            SECTION 7.6 MATERIALITY. Seller and Stockholder hereby agree that
the foregoing noncompetition covenants are a material and substantial part of
this transaction.


          ARTICLE 8.  NON-ASSUMPTION OF LIABILITIES; INDEMNIFICATION

            SECTION 8.1 NON-ASSUMPTION OF LIABILITIES. Except as explicitly set

this Agreement or otherwise, assume, become responsible for or incur any

the generality of the foregoing, any liability or obligation arising out of or
relating to: (a) any occurrence or circumstance (whether known or unknown) which

or agreement (whether written or oral); (b) any injury to or death of any person
or damage to or destruction of any property, whether based on negligence, breach
of warranty, or any other theory; (c) a violation of the requirements of any

liabilities of Seller or Stockholder; (d) the generation, collection,
transportation, storage or disposal by Seller or Stockholder of any materials,
including, without limitation, Hazardous Materials; (e) an agreement or
arrangement between Seller and the employees of Seller or Stockholder or any
labor or collective bargaining unit representing any such employees; (f) the
severance pay obligation of Seller or any employee benefit plan (within the
meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974,
as amended) or any other fringe benefit program maintained or sponsored by
Seller or Stockholder or to which Seller or Stockholder contributes or any
contributions, benefits or liabilities therefor or any liability for the
withdrawal or partial withdrawal from or termination of any such plan or program
by Seller or Stockholder; (g) the debts of Seller or Stockholder; (h) any
litigation against Seller or Stockholder, whether or not listed on Schedule
5.1(h); (i) any liability, obligation, cost or expense related to the Excluded
Assets or the Excluded Business; (j) any liability, obligation cost or expense
related to the Land, including, without limitation, the environmental condition
thereof; and (k) the liabilities or obligations of Seller or Stockholder for

                                      -15-
<PAGE>
agree to indemnify Buyer, its successors and assigns from and against all of the
above liabilities and obligations in accordance with Section 8.3 below.

            SECTION 8.2 ASSUMPTION OF SPECIFIC LIABILITIES. Buyer agrees to
perform all of Seller's contractual obligations related to the Customer Accounts
to the extent, and only to the extent, such obligations first mature and are
required to be performed after the close of business on the Closing Date.

            SECTION 8.3 INDEMNIFICATION BY SELLER AND STOCKHOLDER.
Notwithstanding investigation at any time made by or on behalf of Buyer, Seller
and Stockholder, jointly and severally, agree to defend, indemnify and hold
harmless Buyer, its officers, shareholders, directors, divisions, subdivisions,
affiliates, parent, employees, agents, successors, assigns and the Assets from
and against all losses, claims, actions, causes of action, damages, liabilities,
expenses and other costs of any kind or amount whatsoever (including, without
limitation, reasonable attorneys' fees), whether equitable or legal, matured or
contingent, known or unknown, foreseen or unforeseen, ordinary or extraordinary,
patent or latent, which result, either before or after the date of this
Agreement, from:

            (a) inaccuracy in any representation or warranty made by Seller or
      Stockholder in this Agreement;

            (b) breach of any representation or warranty under this Agreement by
      Seller or Stockholder;

            (c) failure of Seller or Stockholder duly to perform and observe any
      term, provision, covenant, agreement or condition under this Agreement;

            (d) liability of Seller or Stockholder imposed upon Buyer
      (including, without limitation, all liability for the generation,
      collection, transportation, storage or disposal of any materials,
      including, without limitation, Hazardous Materials, whether or not
      disclosed on Schedule 5.1(m) hereof);

            (e) misrepresentation in or omission from any Schedule to this
      Agreement;

            (f) failure of Seller or Stockholder to obtain consent to a Customer
      Account requiring such consent (including, without limitation,
      reimbursement to Buyer of the value of such nonassigned Customer Account);

            (g) liability of Seller or Stockholder imposed upon Buyer as a
      result of Seller's failure to comply with the bulk transfer law of Texas;

                                      -16-
<PAGE>
            (h) liability of Seller or Stockholder resulting from one or more
      pending or threatened lawsuits whether or not listed on Schedule 5.1(h);

            (i) liability of Seller or Stockholder to creditors of Seller or
      Stockholder which is imposed on Buyer whether as a result of bankruptcy
      proceedings or otherwise and whether as an account payable by Seller or
      Stockholder or as a claim of alleged fraudulent conveyance or preferential
      payments within the meaning of the United States Bankruptcy Code or
      otherwise; and

            (j) the existence of creditors of Seller which are not disclosed to
      Buyer;

            (k) any of the matters described in Section 8.1(a)-(k) hereof; and

            (l) any claim by a third party that, if true, would mean that a
      condition for indemnification set forth in this Section 8.3 had been
      satisfied.

Buyer shall be deemed to have suffered such loss, claim, action, cause of
action, damage, liability, expense or other cost, or to have paid or to have
become obligated to pay any sum on account, of, the matters referred to in
subparagraphs (a) - (l) of this Section 8.3 if the same shall be suffered, paid
or incurred by Buyer or any parent, subsidiary, affiliate, or successor of
Buyer. The amount of the loss, claim, action, cause of action, damage,
liability, expense or other cost deemed to be suffered, paid or incurred by
Buyer shall be an amount equal to the loss, claim, action, cause of action,
damage, liability, expense or other cost suffered, paid or incurred by such
parent, subsidiary, affiliate, or successor.

            SECTION 8.4 PROCEDURE FOR INDEMNIFICATION. Promptly after a party
hereto (hereinafter the "Indemnified Party") has received notice of or has
knowledge of any claim by a person not a party to this Agreement ("Third
Person") or the commencement of any action or proceeding by a Third Person, the
Indemnified Party shall, as a condition precedent to a claim with respect
thereto being made against any party obligated to provide indemnification
pursuant to this Agreement (hereinafter the "Indemnifying Party"), give the
Indemnifying Party written notice of such claim or the commencement of such
action or proceeding (the "Notice"). The Notice shall state the nature and the
basis of such claim and a reasonable estimate of the amount thereof. The
Indemnifying Party, after receipt of the Notice, shall defend and settle, at its
own expense and by its own counsel, each such matter so long as the Indemnifying
Party pursues the same diligently and in good faith and the claim does not
involve injunctive or equitable 

                                      -17-
<PAGE>
relief or involve the possibility of criminal penalties. The Indemnified Party
shall cooperate with the Indemnifying Party and its counsel in the defense
thereof and in any settlement thereof. Such cooperation shall include, but shall
not be limited to, furnishing the Indemnifying Party with any books, records or
information reasonably requested by the Indemnifying Party that are in the
Indemnified Party's possession or control. Notwithstanding the foregoing, the
Indemnified Party shall have the right to participate in any matter through
counsel of its own choosing at its own expense, provided that the Indemnifying
Party's counsel shall always be lead counsel and shall determine all litigation
and settlement steps, strategy and the like. After the Indemnifying Party has
received the Notice, the Indemnifying Party shall not be liable for any
additional legal expenses incurred by the Indemnified Party in connection with
any defense or settlement of such asserted liability, except to the extent such
participation is requested by the Indemnifying Party, in which event the
Indemnified Party shall be reimbursed by the Indemnifying Party for reasonable
additional legal expenses, out-of-pocket and allocable share of employee
compensation incurred in connection with such participation for any employee
whose participation is so requested. The foregoing notwithstanding, if the
Indemnifying Party fails diligently to defend any such matter to which the
Indemnified Party is entitled to indemnification hereunder or if the claim
involves injunctive or equitable relief or involves the possibility of criminal
penalties, the Indemnified Party may undertake such defense through counsel of
its choice and at the Indemnifying Party's expense. In each case where the
Indemnifying Party is obligated to pay the costs and expenses of the Indemnified
Party, the Indemnifying Party shall pay the costs and expenses of the
Indemnified Party as such costs and expenses are incurred. If the Indemnifying
Party desires to accept a final and complete settlement of any such Third Person
claim and the Indemnified Party refuses to consent to such settlement, then the
Indemnifying Party's liability under this Section with respect to such Third
Person claim shall be limited to the amount so offered in settlement by said
Third Person and the Indemnified Party shall reimburse the Indemnifying Party
for any additional costs of defense which it subsequently incurs with respect to
such claim.


                              ARTICLE 9.  GENERAL

            SECTION 9.1 FURTHER ASSURANCE. From time to time after the Closing,
Seller and Stockholder will, without further consideration, execute and deliver
such other instruments of conveyance and transfer, and take such other action as
Buyer reasonably may request to more effectively convey and transfer to and vest
in Buyer and to put Buyer in possession of the Assets to be transferred
hereunder, and in the case of contracts and rights, if any, which cannot be
transferred effectively without the consents of third parties, to endeavor to
obtain such consents 

                                      -18-
<PAGE>
promptly, and if any be unobtainable, to use their best efforts to provide Buyer
with the benefits thereof in some other manner. Seller and Stockholder will
cooperate and use their best efforts to have the present officers, directors and
employees of Seller cooperate with Buyer on and after the Closing in furnishing
information, evidence, testimony and other assistance in connection with any
actions, proceedings, arrangements or disputes of any nature with respect to
matters pertaining to all periods prior to the Closing.

            SECTION 9.2 JOINT AND SEVERAL OBLIGATIONS. All representations,
warranties and agreements of Seller or Stockholder under this Agreement, the
Schedules and the transactions contemplated hereby shall be joint and several.

or omission in the exercise of any right, power or remedy accruing to any party
as a result of any breach or default by any other party under this Agreement
shall impair any such right, power or remedy, nor shall it be construed as a
waiver of or acquiescence in any such breach or default, or of or in any similar
breach or default occurring later; not shall any waiver of any single breach or
default be deemed a waiver of any other breach of default occurring before or
after that waiver.

Agreement.

            SECTION 9.6 ENTIRE AGREEMENT. This Agreement, the Schedules hereto
and the other agreements referred to herein constitute the entire agreement and
understanding of the parties with respect to the subject matter hereof, and
supersede all prior and contemporaneous agreements and understandings, oral or
written, relative to said subject matter.

various rights and obligations arising hereunder shall inure to the benefit of
and be binding upon the parties hereto and their respective executors,
administrators, heirs, legal representatives, successors and permitted assigns.
Seller shall have no right to assign this Agreement or any of their respective
rights hereunder. Buyer may assign this Agreement without consent by Seller;
provided, however, that the assignee under such assignment shall agree to assume
the obligations of the assignor under this Agreement. It is further understood
and agreed that Buyer may be merged or consolidated with another entity and that
any such entity shall automatically succeed to the rights, powers and duties of
Buyer hereunder.

            SECTION 9.8 EXPENSES OF TRANSACTION. Seller shall pay all costs and
expenses incurred by Seller or Stockholder in connection with this Agreement and

<PAGE>
expenses of Seller's attorneys and accountants and will make all necessary

as to entitle such dealer, broker or agent to a commission or fee in connection
with the sale of the Assets to Buyer. If for any reason any commission or fee
shall become due, the party dealing with such dealer, broker or agent shall pay
such commission or fee and agrees to indemnify and save the other party harmless

elections available at law or in equity.

            SECTION 9.11 SEVERABILITY. In case any provision of this Agreement
shall be invalid, illegal or unenforceable, it shall, to the extent possible, be
modified in such manner as to be valid, legal and enforceable but so as to most
nearly retain the intent of the parties. If such modification is not possible,
such provision shall be severed from this Agreement. In either case the
validity, legality and enforceability of the remaining provisions of this
Agreement shall not in any way be affected or impaired thereby.

            SECTION 9.12 GOVERNING LAW. This Agreement shall in all respects be
governed by and construed in accordance with the internal laws of the State of
Texas, without giving effect to any choice or conflict of law provision or rule
(whether of the State of Texas or any other jurisdiction) that would cause the
application of the laws of any jurisdiction other than the State of Texas.

            IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be executed as of the day and year first above written.

                      PURCHASE AND SALE OF ASSETS AGREEMENT

        THIS PURCHASE AND SALE OF ASSETS AGREEMENT (the "Agreement") is executed
and delivered as of April 1, 1998, between MESA PROCESSING, INC., a Texas
corporation ("Buyer"); RECLAMATION TECHNOLOGY MANAGEMENT, INC. d/b/a EFFLUENT
TREATMENT SERVICES, INC., a Texas corporation ("Seller") and Don E.
Henley, the sole shareholder of Seller ("Shareholder").

anything to the contrary in this Agreement, to the extent that the assignment
hereunder of any Customer Account shall require the consent of any third party,
neither this Agreement nor any action taken pursuant to its provisions shall

diminution thereof; provided, however, that in each such case, Seller shall use
its best efforts to obtain the consent of such other party to such assignment to
Buyer. If such consent is not obtained, Seller shall cooperate with Buyer in any
reasonable arrangement designed to provide for Buyer the benefits under any such
Customer Account. The Buyer shall be entitled to adjust the purchase price set

obligation whatsoever to Seller in connection with the Accounts Receivable.
However, if Buyer receives any payments which are designated by the customer as
being toward such Accounts Receivable, then Buyer shall forward such payments to
Seller on a regular basis (but at least monthly), together with an itemized list
of the sources thereof. Seller shall not hire an outside agency to collect the
Accounts Receivable, take any legal action on the Accounts Receivable or write
any threatening letters in an attempt to collect Accounts Receivable for a

the close of business on the date of Closing, all cash on hand or on deposit
with Seller consisting of sums paid to Seller pursuant to the advance billing
practice of Seller or otherwise representing a prepayment to Seller of services
to be rendered after the Closing. Seller shall be entitled to all such sums
allocable to services performed on or before the close of business on the date

the date of closing, deliver to Buyer, in form suitable for filing, such
certificates, consents and other documents as are necessary to effect the
transfer of the registration of the Business Names conveyed by Buyer pursuant to
this Agreement in Texas and shall grant any consents and take any other and
further action, all at Seller's own expense, requested by Buyer to enable Buyer
to reserve or register any such name for use of Buyer in Texas.

                             corporation and the parent corporation of Buyer
                             ("Parent"), which shall have an aggregate Agreed
                             Value (as defined in Section 2.2 below) of $500,000
                             calculated in accordance with Section 2.2 below;

                             described therein.

        SECTION 2.2 AGREED VALUE OF PARENT STOCK. For purposes of this

the closing prices of a share of the common stock of Parent, $.01 par value per

        SECTION 2.3   CONTINGENT ADDITIONAL PURCHASE PRICE.

               (a) In addition to the consideration payable pursuant to Section
        2.1(b)(i) and 2.1 (b)(ii) above, Buyer would pay to Seller additional
        consideration in the form of Parent Stock (subject to clause (b) below)
        for the Assets if the operations arising out of the acquired Assets
        (collectively, with the assets to be acquired pursuant to Section 2.3(c)
        below, the "Facility") generate the specified amount of earnings before
        taxes ("Pre-Tax Earnings") (as defined below), as follows:

                      (i) if the Pre-Tax Earnings from the operation of the
               Facility exceeds $335,000 for either the 1998 or the 1999 fiscal
               year, but not both, Buyer shall deliver to Seller that number of
               shares of Parent Stock, which shall have an aggregate value of
               $375,000 (rounded to the nearest whole share with any resulting
               fractional shares paid in cash) determined by using the closing
               price of the Parent Stock, as reported in THE WALL STREET
               JOURNAL, on the last trading day of applicable calendar year,
               1998 or 1999, in which the Pre-Tax Earnings required by this
               subclause (i) were first achieved; and

                      (ii) if the Pre-Tax earnings from the operation of the
               Assets exceeds $405,000 for the 1999 fiscal year or the 2000
               fiscal year, Buyer shall deliver to Seller that number of shares
               of Parent Stock, which shall have an aggregate value of $375,000
               (rounded to the nearest whole share with any resulting fractional
               shares paid in cash) determined by using the closing price of the
               Parent Stock, as reported in THE WALL STREET JOURNAL, on the last
               trading day of applicable calendar year, 1999 or 2000, in which
               the Pre-Tax Earnings required by this subclause (ii) were first
               achieved; and

                      (iii) notwithstanding the above and foregoing, the Seller
               shall not be 
<PAGE>
                entitled to more than one payment under either Section 2.3(a)(i)
                or (ii). Seller shall be entitled to the maximum compensation
                under this Section 2.3(a) (i.e. Parent Stock with an aggregate
                market value of $750,000 at the respective times of issuance)
                if, and only if, the conditions of both subclause (i) and (ii)
                of this Section 2.3(a) are satisfied in two separate years.

               (b) Pre-Tax Earnings will be calculated within 60 days after the
        end of the 1998, 1999 and 2000 fiscal years, respectively, and any
        payments owed to Seller shall be paid on the date that is 90 days after
        the end of the 1998, 1999 and 2000 fiscal years, respectively.

               (c) Buyer agrees to make capital expenditures of up to the
        amounts set forth on Schedule 2.3 attached hereto toward the purchase of
        the various assets described on such Schedule 2.3 for use at the
        Facility. Each such purchase shall be subject to the submission of
        appropriate capital purchase orders in accordance with Buyer's corporate
        policies. If Buyer fails to make the required capital expenditures prior
        to December 31, 1998, unless such failure is occasioned by events
        outside of Buyer's reasonable control or the acts or omissions of Seller
        or Shareholder, the condition precedent to Seller's entitlement to the
        contingent consideration set forth in Section 2.3(a)(i) above shall be
        deemed satisfied. If Buyer has failed to make the required capital
        expenditures prior to December 31, 1999, unless such failure is
        occasioned by events outside of Buyer's reasonable control or the acts
        or omissions of Seller or Shareholder, the condition precedent to
        Seller's entitlement to the contingent consideration set forth in
        Section 2.3(a)(ii) above shall be deemed satisfied. The parties agree
        that there shall exist no other state of facts, other than actual
        satisfaction of such conditions, which shall cause the conditions set
        forth in Section 2.3(a)(i) or (ii) to be deemed satisfied.

               (d) For purposes of this Agreement, "Pre-Tax Earnings" shall mean
        the gross revenues derived from the Assets calculated in accordance with
        generally accepted accounting principles ("GAAP") minus (i) all costs
        incurred in operating the Facility (including, without limitation, all
        payroll costs, equipment operating costs, insurance costs, maintenance
        costs, legal, accounting and other professional fees, all depreciation,
        depletion and amortization expenses, all selling, general and
        administrative costs, interest and all other operating expenses); all
        taxes on operations of the Facility such as franchise taxes, real and
        personal property taxes, use taxes and sales taxes (but specifically
        excluding all federal, state (if any) and local income taxes); (iii)
        reserves for financial assurance, closure and post closure costs and
        doubtful accounts of the Facility; and (iv) 2% of such gross revenues
        constituting a charge for corporate overhead. All of the foregoing shall
        be determined by Buyer in accordance with Parent's past practices and in
        accordance with GAAP. Corporate overhead charges relating to operations
        outside the Facility shall not exceed 2% of the gross revenues generated
        by the operation of the Facility.

                                   ARTICLE III

               (c) motor vehicle Certificates of Title and/or registrations to

        Price;
     
               (e) fully executed consents to the assignment of the Customer

        transfer reasonably required by Buyer.

        SECTION 3.3 DELIVERIES BY BUYER. At the Closing, Buyer shall deliver to
Seller the Purchase Price set forth in Section 2.1(a) and (d) and shall assume
all obligations to make rent and other contractual payments arising after the
Closing Date under the leases of the Facility. Rent for the month in which the
Closing occurs shall be prorated and paid by the respective parties based on the
number of days in the month the Facility was occupied by each party. Taxes,
assessments and other charges required to be paid by the tenant under the
leases, and not paid prior to Closing, shall be prorated between the parties
based upon the number of days in the tax year each of Buyer and Seller occupied
the Facility.

                                   ARTICLE IV

                       COVENANTS OF SELLER AND SHAREHOLDER

               whatsoever.

               (b) COMPLIANCE WITH LAW. Neither Seller nor the Shareholder is in
        default under any applicable federal, state or local laws, statutes,
        ordinances, permits, licenses, orders, approvals, variances, rules or
        regulations or judicial or administrative decisions ("Applicable Laws")
        which would have an adverse effect upon the Assets or the Business.
        Seller has been granted all licenses, permits, consents, authorizations
        and approvals from federal, state and local government regulatory bodies
        necessary or desirable to carry on the Business, all of which are
        currently in full force and effect. Each of the Assets complies in all
        respects with all federal, state and local laws, statutes, ordinances,
        permits, licenses, approvals, rules and regulations applicable thereto.

               (c) EQUIPMENT. Listed on Schedule 1.1(a) hereto is a complete and
        accurate list of all equipment used or for use in connection with the
        Business. Each piece of Equipment is in good working order and repair.

               (d) OFFICE FURNISHINGS. Listed on Schedule 1.1(b) is a complete
        and accurate list of all Office Furnishings. All items of Office
        Furnishings are in good working order and repair.

               (e) ROLLING STOCK. Listed on Schedule 1.1(c) hereto is a complete

        accessory and piece of materials handling equipment comprising the
        Rolling Stock is in good working order and repair.

               (f) CUSTOMER ACCOUNTS. Listed on Schedule 1.1(d) hereto is a
        complete and accurate list of the Customer Accounts as of the date
        hereof. Except as set forth on Schedule 1.3, all Customer Accounts are
        (and will be immediately following the Closing) in full force and effect
        and are valid, binding and enforceable against the respective parties
        thereto in accordance with their respective provisions, and Seller is
        not in default in, nor has there occurred an event or condition
        (including Seller's execution and delivery of or performance under this
        Agreement) which with the passage of time or the giving of notice (or
        both) would constitute a default, with regard to the payment or
        performance of any obligation under any Customer Account; no claim of
        such a default has been asserted and there is no reasonable basis upon
        which such a claim could validly be made. Neither Seller nor Shareholder
        has received any notice that any person intends or desires to modify,
        waive, amend, rescind, release, cancel or terminate any Customer
        Account. By virtue of the grant, conveyance, sale, transfer and
        assignment of the Customer Accounts by Seller to Buyer hereunder, Buyer
        shall own and hold all right, title and interest of Seller in and to the
        Customer Accounts, without the consent or approval of any other

<PAGE>
        person or entity.

               (g) TITLE TO THE PERSONAL PROPERTY. Seller has good and
        marketable title to all of the Assets constituting personal property,
        free and clear of all liens, encumbrances, security interests, equities
        or restrictions whatsoever and, by virtue of the grant, conveyance,
        sale, transfer, and assignment of the Assets hereunder, Buyer shall
        receive good and marketable title to all of the Assets constituting
        personal property, free and clear of all liens, lease payments
        (including lease-end buy-out payments), encumbrances, security
        interests, equities or restrictions whatsoever. The Assets include all
        of the permits, licenses, franchises, consents and other approvals
        necessary or desirable to conduct the Business.

               (h) TITLE TO REAL PROPERTY. Seller has never owned, leased or
        otherwise occupied, had an interest in or operated any real property
        other than the Facility. Seller has good, leasehold title to the
        Facility. Attached hereto as Schedule 5.1(h) are true and complete
        copies of the leases of the Facility. Except as set forth on Schedule
        5.1(h):

                      (i) The Facility is, and at all times during operation of
               the Business has been, fully licensed, permitted and authorized
               for the operation of the Business under all Applicable Laws
               relating to the protection of the environment, the Facility and
               the conduct of the Business thereon (including, without
               limitation, all zoning restrictions and land use requirements).

                      (ii) The Facility is usable for its current uses and can
               be used by Buyer after the Closing for such uses without
               violating any applicable law or private restriction, and such
               uses are legal conforming uses. There are no proceedings or
               amendments pending and brought by or, to the best of Seller's
               knowledge, threatened by, any third party which would result in a
               change in the allowable uses of the Facility or which could
               modify the right of Buyer to use the Facility for its current
               uses after the Closing Date.

                      (iii) Shareholder and Company have made available to Buyer
               all engineering, geologic and other similar reports,
               documentation and maps relating to the Facility in the possession
               or control of Seller.

                      (iv) Neither Seller, Shareholder nor the Facility now is
               or ever has been involved in any litigation or administrative
               proceeding seeking to impose fines, penalties or other
               liabilities or seeking injunctive relief for violation of any
               Applicable Laws relating to the environment.

               (i) LITIGATION. Except as set forth on Schedule 5.1(i) hereof,
        there is no claim, litigation, action, suit or proceeding,
        administrative or judicial, pending or threatened against Seller or
        Shareholder, or involving the Assets or the Business, at law or in
        equity, before any federal, state or local court or regulatory agency,
        or other governmental authority. Neither Seller nor Shareholder has
        received any notice of any of the above and no facts or circumstances
        exist which would, with the passage of time or giving of notice (or
        both), give rise to any of the above.

               (j) EMPLOYEES. Attached as Schedule 5.1(j) hereof is a complete
        list of all employees of Seller and their respective rates of
        compensation (including a breakdown of the portion thereof attributable
        to salary, bonus and other compensation, respectively) as of the date of
        Closing. Each employee is an employee at will and there are no
        collective bargaining agreements affecting any employee of Seller. Buyer
        shall not be obligated to hire any of Seller's employees.

               (k) EMPLOYEE RELATIONS AND BENEFIT PLANS. Set forth on Schedule
        5.1(k) is an accurate and complete list of all agreements of any kind
        between Seller and its employees or group of employees, including,
        without limitation, employment agreements, collective bargaining
        agreements and benefit plans. Buyer shall not, by the execution and
        delivery 
<PAGE>
        of this Agreement or otherwise, become obligated to or assume any
        liabilities or contractual obligations with respect to any employee of
        Seller or otherwise become liable for or obligated in any manner
        (contractual or otherwise) to any employee of Seller, including, without
        limiting the generality of the foregoing, any liability or obligation
        pursuant to any collective bargaining agreement, employment agreement,
        or pension, profit sharing or other employee benefit plan (within the
        meaning of Section 3(3) of the Employment Retirement Income Security Act
        of 1974, as amended) or any other fringe benefit program maintained by
        Seller or to which Seller contributes or any liability for the
        withdrawal or partial withdrawal from or termination of any such plan or
        program by Seller.

               (l) FINANCIAL STATEMENTS. Attached hereto as Schedule 5.1(l) are
        copies of Seller's balance sheet as of December 31, 1997, and a
        statement of income, cash flow and retained earnings for the year ended
        December 31, 1997, and Seller's balance sheet as of March 31, 1998 (the
        "Balance Sheet Date"), and a statement of income, cash flow and retained
        earnings for the three-month period then ended (the "Financial
        Statements"). The Financial Statements (including any footnotes thereto)
        have been prepared in accordance with GAAP, applied on a consistent
        basis throughout the periods indicated. The Financial Statements
        (including all footnotes thereto) are true, complete and correct and
        present fairly the financial condition and the results of the operations
        of Seller for the period indicated thereon. All reserves for contingent
        risks have been estimated in accordance with GAAP and are appropriate
        and sufficient to cover all costs reasonably expected to be incurred
        from such risks. The Financial Statements are consistent with the books
        and records of Seller (which books and records are correct and complete.

               (m) TAXES. No federal, state, local or other tax returns or
        reports filed by Seller (whether filed prior to, on or after the date
        hereof) with respect to the Business or the Assets will result in any
        taxes, assessments, fees or other governmental charges upon the Assets
        or Buyer, whether as a transferee of the Assets or otherwise. All
        federal, state and local taxes due and payable with respect to the
        Business or the Assets have been paid, including, without limiting the
        generality of the foregoing, all federal, state and local income, sales,
        use franchise, excise and property taxes.

               (n) HAZARDOUS MATERIALS. Neither Seller nor Shareholder has ever
        generated, transported, stored, handled recycled, reclaimed, disposed
        of, or contracted for the disposal of, hazardous materials, hazardous
        wastes, hazardous substances, toxic wastes or substances, infectious or
        medical waste, radioactive waste or sewage sludges as those terms are
        defined by the Comprehensive Environmental Response, Compensation and
        Liability Act of 1980 ("CERCLA"); the Atomic Energy Act of 1954; the
        Toxic Substances Control Act; the Occupational Health and Safety Act;
        any comparable or similar Texas statute; or the rules and regulations
        promulgated under any of the foregoing, as each of the foregoing may
        have been from time to time amended (collectively, "Hazardous
        Materials"). Seller has never owned, operated, had an interest in,
        engaged in and/or leased a waste transfer, recycling, treatment, storage
        or disposal facility, business or activity other than the Business.
        Seller has obtained and maintained all necessary trip tickets, signed by
        the applicable waste generators, and other records demonstrating the
        nature of the waste transported in connection with the Business. No
        employee, contractor or agent of Seller has, in the course and scope of
        employment with Seller, been harmed by exposure to Hazardous Materials.
        Seller has no direct or contingent liability or obligation for or in
        connection with any claimed release, discharge or leak of any substance
        onto the Facility or into the environment. Further, no portion of

                                            - 12 -


<PAGE>



        the Facility is listed on the CERCLA list or the National Priorities
        List of Hazardous Waste Sites or any similar list maintained by the
        State of Texas. Attached hereto as Schedule 5.1(n) is a complete list of
        the names and addresses of all disposal sites at any time now or in the
        past utilized by Seller, none of which sites is listed on the CERCLA
        list or the National Priorities List of Hazardous Waste Sites or any
        comparable Texas list. Neither Seller, Shareholder nor the Facility is
        listed as a potentially responsible party under CERCLA or any comparable
        or similar state statute; neither Seller nor Shareholder has received
        any notice of such a listing; and neither Seller nor Shareholder knows
        of any 
<PAGE>
        facts or circumstances which could give rise to such a listing.

               (o) GOVERNMENT NOTICES. Seller has delivered to Buyer, a
        description and copies, as of the date of this Agreement, of all
        notifications, filed or submitted, or required to be filed or submitted,
        to governmental agencies and of all material notifications from such
        governmental agencies relating to Seller and the Assets or relating to
        the discharge or release of materials into the environment or otherwise
        relating to the protection of the public health or the environment.

               (p) ABSENCE OF PRICE RENEGOTIATION CONTRACTS. Seller is not now
        nor has ever been a party to any governmental contracts subject to price
        redetermination or renegotiation.

               (q) GROSS REVENUES. The gross revenues generated by the Business
        for the 12-month period immediately preceding the month in which the
        Closing occurs were $483,062.

               (r) UNDERGROUND STORAGE TANKS. Except for the Facility, Seller
        has never owned, leased or operated any real estate having any
        underground storage tanks containing petroleum products or wastes or
        other hazardous substances regulated by 40 CFR 280 and/or other
        applicable federal, state or local laws, rules and regulations and
        requirements. Set forth on Schedule 5.1(r) is a list of all above and
        below ground tanks located on the Facility, each of which are being used
        and maintained in accordance with Applicable Laws.

               (s) COMPLETENESS OF DISCLOSURE. This Agreement and the Schedules
        hereto and all other documents and information furnished to Buyer and
        its representatives pursuant hereto do not and will not include any
        untrue statement of a material fact or omit to state a material fact
        necessary to make the statements therein not misleading. If Seller or
        Shareholder become aware of any fact or circumstance which would change
        a representation or warranty of Seller or Shareholder in this Agreement,
        the party with such knowledge shall immediately give notice of such fact
        or circumstance to Buyer. However, such notification shall not relieve
        Seller or Shareholder of their obligations under this Agreement, and at
        the sole option of Buyer, the truth and accuracy of any and all
        warranties and representations of Seller and Shareholder at the date of
        this Agreement shall be a precondition to the consummation of this
        transaction.

        SECTION 5.2 SURVIVAL. Each of the representations and warranties set
forth in this Article V shall survive the Closing and the transfer of the
Assets.

                                   ARTICLE VI

               REPRESENTATIONS AND WARRANTIES OF BUYER AND PARENT

        SECTION 6.1 Buyer and Parent represent and warrant to Seller and
Shareholder that:

        (a) CORPORATE ORGANIZATION. Buyer is a corporation duly organized,
validly existing and in good standing under the laws of the State of Texas.
Parent is a corporation duly organized, validly existing and in good standing
under the laws of the State of Delaware.

        (b) AUTHORIZATION. Buyer and Parent each have all requisite corporate
power and corporate authority to enter into this Agreement, perform its
respective obligations hereunder and consummate the transactions contemplated
hereby. The execution and delivery of this Agreement, the consummation of the
transactions contemplated hereby and the compliance by Buyer and Parent with the
terms of this Agreement do not and will not conflict with or result in a breach
of any terms of, or constitute a default under, Buyer's Articles of
Incorporation or Bylaws or any other agreement or instrument to which Buyer or
Parent is a party or by which Buyer or Parent is bound. All necessary corporate
action has been taken by Buyer and Parent with respect to the execution and
delivery of this Agreement, and this Agreement constitutes a valid 
<PAGE>
obligation of Buyer and Parent enforceable in accordance with its terms except
as limited by bankruptcy, insolvency, reorganization or other such laws
concerning the rights of creditors.

        (c) PARENT STOCK. The Parent Stock to be delivered to Seller in
connection with this Agreement, when delivered in accordance with the terms of
this Agreement, will constitute valid and legally issued shares, fully paid and
nonassessable, and will be registered and free from any restriction on transfer
other than restrictions imposed by the Securities Act of 1993, as amended, or
the regulations promulgated thereunder.

        SECTION 6.2 SURVIVAL. Each of the representations and warranties set
forth in this Article VI shall survive the Closing and the transfer of the
Assets.

                                   ARTICLE VII

                                 NONCOMPETITION

        SECTION 7.1 NONCOMPETITION COVENANTS. Seller and Shareholder, jointly
and severally, agree that for a period of ten years following the date of
Closing, neither of them shall directly or indirectly, through a subsidiary or
affiliate, without the prior express written consent of Buyer:

                (i) engage, whether as a corporation on its own account, or as
        an officer, director, shareholder, owner, partner, joint venturer,
        investor, agent, or in a managerial capacity, whether as an employee,
        independent contractor, consultant or advisor, or as a sales
        representative, in the business of: siting, developing, constructing,
        permitting or operating a facility for the processing, treatment or
        disposal of non-hazardous liquid waste (including, without limitation,
        waste oil, waste water, grease trap waste, grit trap waste and oil
        contaminated water); siting, developing, constructing, permitting or
        operating a facility for the processing, treatment and disposal of
        non-hazardous oilfield waste (including, without limitation, chlorides,
        heavy metals, cuttings, contaminated soils, drilling fluids and pit
        sludges); and transportation or collection of any such materials, in
        each case within a radius of 200 air miles of Seller's facilities in
        Haltom City, Texas (the "Territory");

               (ii) call upon any person who is, at that time, within the
        Territory, an employee of Buyer in a managerial capacity for the purpose
        or with the intent of enticing such employee away from or out of the
        employ of Buyer;

               (iii) call upon any person or entity which is, at that time, or
        which has been, within two years prior to that time, a customer of
        Seller or Buyer, as the case may be, within the Territory for the
        purpose of: siting, developing, constructing, permitting or operating a
        facility for the processing, treatment or disposal of non-hazardous
        liquid waste (including, without limitation, waste oil, waste water,
        grease trap waste, grit trap waste and oil contaminated water); siting,
        developing, constructing, permitting or operating a facility for the
        processing, treatment and disposal of non-hazardous oilfield waste
        including, without limitation, chlorides, heavy metals, cuttings,
        contaminated soils, drilling fluids and pit sludges); and transportation
        or collection of any such materials, in each case within the Territory;

               (iv) call upon any prospective acquisition candidate, on their
        own behalf or on behalf of any competitor, which candidate was either
        called upon by Seller or Shareholder or for which Seller or Shareholder
        made an acquisition analysis for Seller or Buyer;

               (v) disclose the identity of Buyer's customers, whether in
        existence or proposed, to any person, firm, partnership, corporation or
        business for any reason or purpose whatsoever; or

               (vi) promote or assist, financially or otherwise (including,
        without limitation, lending, guaranteeing loans or otherwise providing
        financial assurance in any way), any 
<PAGE>
        person, firm, partnership, corporation or other entity whatsoever to do
        any of the above.

        Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit Seller or Shareholder from (i) marketing or selling MIDOS technology or
consulting with other companies in the use of the MIDOS technology, provided
that no such activities targeted to businesses in the waste treatment industry
will take place within the Territory, nor will any such activities be reasonably
likely to have an adverse effect on the Business or the operations of the
Facility, and (ii) acquiring as an investment not more than one percent of the
capital stock of a competing business, whose stock is traded on a national
securities exchange or over-the-counter.

        SECTION 7.2 INJUNCTIVE RELIEF. Because of the difficulty of measuring
economic losses to Buyer as a result of the breach of the foregoing covenant,
and because of the immediate and irreparable damage that would be caused to
Buyer for which it would have no other adequate remedy, Seller and Shareholder
agree that, in the event of breach by any of them of the foregoing covenant, the
covenant may be enforced by Buyer by, without limitation, injunctions and
restraining orders.

        SECTION 7.3 REASONABLENESS OF COVENANTS. It is agreed by the parties
that the foregoing covenants in this Article VII impose a reasonable restraint
on Seller and Shareholder in light of the activities and business of the Buyer
on the date of the execution of this Agreement and future plans of the Buyer.

        SECTION 7.4 SEVERABILITY OF COVENANTS. The covenants in this Article VII
are severable and separate, and the unenforceability of any specific covenant
shall not affect the provisions of any other covenants. Moreover, in the event
any court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

        SECTION 7.5 INDEPENDENT COVENANTS. All of the covenants in this Article
VII shall be construed as an agreement independent of any other provision of
this Agreement, and the existence of any claim or cause of action of Seller or
Shareholder against Buyer, whether predicated on this Agreement or otherwise,
shall not constitute a defense to the enforcement by Buyer of such covenants. It
is specifically agreed that the duration of the noncompetition covenants stated
above shall be computed by excluding from such computation any time during which
Seller or Shareholder is in violation of any provision of this Article VII.

        SECTION 7.6 MATERIALITY. Seller and Shareholder hereby agree that the
foregoing noncompetition covenants are a material and substantial part of this
transaction.

                                  ARTICLE VIII

                 NON-ASSUMPTION OF LIABILITIES; INDEMNIFICATION

        SECTION 8 NON-ASSUMPTION OF LIABILITIES. Except as explicitly set forth
in Section 8.2 below, Buyer shall not, by the execution and performance of this
Agreement or otherwise, assume, become responsible for or incur any liability or
obligation of any nature of Seller or Shareholder whether legal or equitable,
matured or contingent, known or unknown, foreseen or unforeseen, ordinary or
extraordinary, patent or latent, whether arising out of occurrences prior to, at
or after the date of this Agreement, including, without limiting the generality
of the foregoing, any liability or obligation arising out of or relating to: (a)
any occurrence or circumstance (whether known or unknown) which occurs or exists
on or prior to the date of this Agreement and which constitutes, or which by the
lapse of time or giving notice (or both) would constitute, a breach or default
under any lease, contract, or other instrument or agreement whether written or
oral); (b) any injury to or death of any person or damage to or destruction of
any property, whether based on negligence, breach of warranty, or any other
theory; (c) a violation of the requirements of any governmental authority or of
the rights of any third person, including, without limitation, any requirements
relating to the reporting and payment of federal, state, local or other income,
sales, use, franchise, excise or property tax liabilities of Seller or
<PAGE>
Shareholder; (d) the generation, collection, transportation, storage or disposal
by Seller or Shareholder of any materials, including, without limitation,
hazardous materials; (e) an agreement or arrangement between Seller and the
employees of Seller or Shareholder or any labor or collective bargaining unit
representing any such employees; (f) the severance pay obligation of Seller or
any employee benefit plan (within the meaning of Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended) or any other fringe benefit
program maintained or sponsored by Seller or Shareholder or to which Seller or
Shareholder contributes or any contributions, benefits or liabilities therefor
or any liability for the withdrawal or partial withdrawal from or termination of
any such plan or program by Seller or Shareholder; (g) the debts of Seller or
Shareholder; (h) any litigation against Seller or Shareholder, whether or not
listed on Schedule 5.1(h); (i) any liability, obligation cost or expense related
to the Facility related to the time prior to the Closing Date, including,
without limitation, the environmental condition thereof; and (k) the liabilities
or obligations or Seller or Shareholder for brokerage or other commissions
relative to this Agreement or the transactions contemplated hereunder. Seller
and Shareholder each agree to indemnify Buyer, its successors and assigns from
and against all of the above liabilities and obligations in accordance with
Section 8.3 below.

        SECTION 8.2 ASSUMPTION OF SPECIFIC LIABILITIES. Buyer agrees to perform
all of Seller's contractual obligations related to the Customer Contracts and
the leases of the Facility to the extent, and only to the extent, such

                (b) breach of any representation or warranty under this
        Agreement by Seller or Shareholder;

                (c) failure of Seller or Shareholder duly to perform and observe
        any term, provision, covenant, agreement or condition under this
        Agreement;

                (d) liability of Seller or Shareholder imposed upon Buyer

<PAGE>
        otherwise; and

                (i) the existence of creditors of Sellers which are not

        condition for indemnification set forth in this Section 8.3 had been
        satisfied.

Buyer shall be deemed to have suffered such loss, claim, action, cause of
action, damage, liability, expense or other cost, or to have paid or to have
become obligated to pay any sum on account, of, the matters referred to in
subparagraphs (a) - (l) of this Section 8.3 if the same shall be suffered, paid

Buyer. The amount of the loss, claim, action, cause of action, damage,
liability, expense or other cost deemed to be suffered, paid or incurred by
Buyer shall be an amount equal to the loss, claim, action, cause of action,
damage, liability, expense or other cost suffered, aid or incurred by such
parent, subsidiary, affiliate, or successor.

        SECTION 8.4 PROCEDURE FOR INDEMNIFICATION. Promptly after a party hereto
(hereinafter the "Indemnified Party") has received notice of or has knowledge of
any claim by a person not a party to this Agreement ("Third Person" or the
commencement of any action or proceeding by a Third Person, the Indemnified
Party shall, as a condition precedent to a claim with respect thereto being made
against any party obligated to provide indemnification pursuant to this
Agreement (hereinafter the "Indemnifying Party"), give the Indemnifying Party
written notice of such claim or the commencement of such action or proceeding
(the "Notice"). The Notices shall state the nature and the basis of such claim
and a reasonable estimate of the amount thereof. The Indemnifying Party, after
receipt of the Notice, shall defend and settle, at its own expense and by its
own counsel, each such matter so long as the Indemnifying Party pursues the same
diligently and in good faith and the claim does not involve injunction or
equitable relief or involve criminal penalties. The Indemnified Party shall
cooperate with the Indemnifying Party and its counsel in the defense thereof and
in any settlement thereof. Such cooperation shall include, but shall not be
limited to, furnishing the Indemnifying Party with any books, records or
information reasonably requested by the Indemnifying Party that are in the
Indemnified Party's possession or control. Notwithstanding the foregoing, the
Indemnified Party shall have the right to participate in any matter through
counsel of its own choosing at its own expense, provided that the Indemnifying
Party's counsel shall always be lead counsel and shall determine all litigation
and settlement steps, strategy and the like. After the Indemnifying Party has
received the Notice, the Indemnifying Party shall not be liable for any
additional legal expenses incurred by the Indemnified Party in connection with
any defense or settlement of such asserted liability, except to the extent such
participation is requested by the Indemnifying Party, in which event the
Indemnified Party shall be reimbursed by the Indemnifying Party for reasonable
additional legal expenses, out-of-pocket and allocable share of employee
compensation incurred in connection with such participation for any employee
whose participation is so requested. The foregoing notwithstanding, if the
Indemnifying Party fails diligently to defend any such matter to which the
Indemnified Party is entitled to indemnification hereunder or if the claim
involves criminal penalties, the Indemnified Party may undertake such defense
through counsel of its choice and at the Indemnifying Party's expense. In each
case where the Indemnifying Party is obligated to pay the costs and expenses of
the Indemnified Party, the Indemnifying Party shall pay the costs and expenses
of the Indemnified Party as such costs and expenses are incurred. If the
Indemnifying Party desires to accept a final and complete settlement of any such
Third Person claim and the Indemnified Party refuses to consent to such
settlement, then the Indemnifying Party's liability under this Section with
respect to such Third Person claim shall be limited to the amount so offered in
settlement by said Third Person and the Indemnified Party shall reimburse the
Indemnifying Party for any additional costs of defense which it subsequently
incurs with respect to such claim.

                                   ARTICLE IX

                        NONDISCLOSURE AND CONFIDENTIALITY
<PAGE>
        SECTION 9.1 NONDISCLOSURE AND CONFIDENTIALITY AGREEMENT. Buyer agrees
not to disclose to any other person, corporation, or entity any information
relating to the MIDOS machine or process, except for information that is or
becomes generally known or in the public domain or with respect to which, based
on an opinion of its legal counsel, it is compelled to produce by court order or
other legal process. Buyer shall take all reasonable action necessary to prevent
any of its employees, representatives and agents (other than Shareholder or his
affiliates) from disclosing any confidential information related to the MIDOS
machine and process. Buyer shall not use the MIDOS technology in any way without
the express permission of Shareholder. Buyer acknowledges that the MIDOS
technology is a trade secret of Shareholder.

        SECTION 9.2 DAMAGES. Buyer agrees that it shall be responsible for any
damages to Seller and Shareholder that result from any disclosure of the MIDOS
technology by Buyer.

        SECTION 9.3 INJUNCTIVE RELIEF. Because of the difficulty of measuring
economic losses to Seller and Shareholder as a result of the breach of the
foregoing covenant, and because of the immediate and irreparable damage that
would be caused to Seller and Shareholder for which it would have no other
adequate remedy, Buyer agrees that, in the event of breach by any of them of the
foregoing covenant, the covenant may be enforced by Seller and Shareholder by,
without limitation, injunctions and restraining orders.

        SECTION 9.4 SURVIVAL. The representations and warranties set forth in
this Article IX shall survive the Closing.

        SECTION 9.5 OBLIGATIONS OF SELLER AND SHAREHOLDER. Seller and
Shareholder jointly and severally agree that they shall take all reasonable
actions and precautions to protect their proprietary information relating to the
MIDOS technology, including without limitation, maintaining all records,
prototypes and other materials of a confidential nature in a secure location
away from the Facility, disclosing confidential information only to persons with
a need to know such information and only if such persons are obligated to retain
such information in confidence. Seller shall not disclose any confidential
information regarding the MIDOS technology to any employee, representative or
agent of Buyer without providing Buyer with written notice of such disclosure to
enable Buyer to fulfill its obligations under this Article IX.

        SECTION 9.6 INDEPENDENT COVENANTS. All of the covenants in this Article
IX shall be construed as an agreement independent of any other provisions of
this Agreement and the existence of any claim or cause of action of Buyer
against Seller or Shareholder, whether predicated on this Agreement or otherwise
(except for any claims of Seller's or Shareholder's breach of Section 9.5
above), shall not constitute a defense to the enforcement by Shareholder or
Seller of this Article IX.

                                    ARTICLE X

                                MIDOS TECHNOLOGY

to Buyer a right of first refusal for the period beginning on the date hereof
and ending at 11:59 p.m. on December 31, 2000. In the event Seller and/or
Shareholder receives an offer to purchase the MIDOS machine and/or technology,
the Seller and/or Shareholder must promptly submit to Buyer a written
notification of such offer setting forth all of the terms of the proposed sale.
The Buyer shall have the irrevocable right and option to purchase the MIDOS
machine and technology, including without limitation all records, prototypes,
drawings and other information pertaining thereto, on the same terms as are
applicable to the offer. Buyer may exercise this right and option by notifying
Seller and/or Shareholder in writing of its election within 45 days after Buyer
receives the written offer. If Buyer does not notify Seller and/or Shareholder
within such 45 day period, the sale to the offering third party may be
consummated, provided that such sale must take place within a 60 day period
after lapse of the option period, and must be consummated pursuant to the same
terms as were set forth in the offer notice.

        SECTION 10.02 NO MARKETING TO WASTE TREATMENT COMPANIES. Seller and/or
Shareholder 
<PAGE>
shall not market the MIDOS machine and/or technology to other waste treatment
companies until after December 31, 2000.

        SECTION 10.03 RIGHT TO SELL TO UNRELATED INDUSTRIES. Seller and/or
Shareholder will retain the right to sell the MIDOS machine and/or technology to
persons in industries unrelated to waste treatment. In the event Seller and/or
Shareholder sells the MIDOS machine and/or technology to a purchaser in an
unrelated industry, Seller and/or Shareholder shall obtain an agreement from the
purchaser that they will not market or sell the MIDOS machine and/or technology
to a waste treatment company until after December 31, 2000.

        SECTION 1.3 NON-ASSIGNMENT OF CERTAIN CUSTOMER ACCOUNTS. Notwithstanding
anything to the contrary in this Agreement, to the extent that the assignment
hereunder of any Customer Account shall require the consent of any third party,
neither this Agreement nor any action taken pursuant to its provisions shall
constitute an assignment or an agreement to assign if such assignment or
attempted assignment would constitute a breach thereof or result in the loss or
diminution thereof; provided, however, that in each such case, Seller shall use
its best efforts to obtain the consent of such other party to such assignment to
Buyer. If such consent is not obtained, Seller shall cooperate with Buyer in any
reasonable arrangement designed to provide for Buyer the benefits under any such
Customer Account, including without limitation, an adjustment of the purchase

benefit of Buyer, of any and all rights of Seller against any other person

to be rendered after the Closing. Seller shall be entitled to all such sums
allocable to services performed on or before the close of business on the date
of Closing and Buyer shall be entitled to all such sums allocable to services to
be performed thereafter. Buyer and Seller agree that the amount of such prepaid
services to be credited to Buyer is $0.00.

all necessary action to change Seller's current Business Name to a name not the
same as or similar to Betts Pump Service, Inc. or any other symbol, trademark,

                         REPRESENTATIONS AND WARRANTIES
                            OF SELLER AND SHAREHOLDER

        SECTION 5.1 Seller and Shareholder, jointly and severally, represent and
warrant to Buyer that:

               (a)    AUTHORITY.

                      (i) Seller is a corporation duly formed, validly existing
               and in good standing under the laws of the State of Texas. The
               execution and delivery of this Agreement, the consummation of the
               transactions contemplated hereby and the compliance by Seller and
               Shareholder with the terms of this Agreement do not and will not
               conflict with or result in a breach of any terms of, or
               constitute a default under, the articles of incorporation or
               bylaws of Seller, or any instruments or other agreement to which
               Seller or Shareholder are a party or by which Seller or
               Shareholder are bound. This Agreement constitutes a valid
               obligation of Seller and Shareholder enforceable against Seller
               and Shareholder in accordance with its terms except as limited by
               bankruptcy, insolvency, reorganization or other such laws
               concerning the rights of creditors.

                      (ii) Shareholder is competent, under no duress or legal
               restraint, and has all necessary authority to enter into this
               Agreement, perform his obligations hereunder and consummate the
               transactions contemplated hereby.

                      (iii) All of the issued and outstanding shares of Seller
               are owned of record and beneficially by Shareholder, free and
               clear of all liens, security interests and encumbrances
               whatsoever.

               (b) COMPLIANCE WITH LAW. Neither Seller nor the Shareholder is in
        default under any applicable federal, state or local laws, statutes,
        ordinances, permits, licenses, orders, approvals, variances, rules or
        regulations or judicial or administrative decisions ("Applicable Laws")
        which would have an adverse effect upon the Assets or the Business.
        Seller has been granted all licenses, permits, consents, authorizations
        and approvals from federal, state and local government regulatory bodies
        necessary or desirable to carry on the Business, all of which are
        currently in full force and effect. Each of the Assets
<PAGE>
        complies in all respects with all federal, state and local laws,
        statutes, ordinances, permits, licenses, approvals, rules and
        regulations applicable thereto.

        complete and accurate list of the Customer Accounts as of the date
        hereof. Except as set forth on Schedule 1.3, all Customer Accounts are
        (and will be immediately following the Closing) in full force and effect
        and are valid, binding and enforceable against the respective parties
        thereto in accordance with their respective provisions, and Seller is
        not in default in, nor has there occurred an event or condition
        (including Seller's execution and delivery of or performance under this
        Agreement) which with the passage of time or the giving of notice (or
        both) would constitute a default, with regard to the payment or
        performance of any obligation under any Customer Account; no claim of
        such a default has been asserted and there is no reasonable basis upon
        which such a claim could validly be made. Neither Seller nor Shareholder
        has received any notice that any person intends or desires to modify,
        waive, amend, rescind, release, cancel or terminate any Customer
        Account. By virtue of the grant, conveyance, sale, transfer and
        assignment of the Customer Accounts by Seller to Buyer hereunder, Buyer

        Customer Accounts, without the consent or approval of any other person
        or entity.

               (f) TITLE TO THE PERSONAL PROPERTY. Seller has good and
        marketable title to all of the Assets constituting personal property,
        free and clear of all liens, encumbrances, security interests, equities
        or restrictions whatsoever except the Assumed Debt and, by virtue of the
        grant, conveyance, sale, transfer, and assignment of the Assets
        hereunder, Buyer shall receive good and marketable title to all of the
        Assets constituting personal property, free and clear of all liens,
        lease payments (including lease-end buy-out payments), encumbrances,
        security interests, equities or restrictions whatsoever except the
        Assumed Debt. The Assets include all of the permits, licenses,
        franchises, consents and other approvals necessary or desirable to
        conduct the Business.

               (g) LITIGATION. Except as set forth on Schedule 5.1(g) hereof,
        there is no claim, litigation, action, suit or proceeding,
        administrative or judicial, pending or threatened against Seller or
        Stockholders, or involving the Assets or the Business, at law or in
        equity, before any federal, state or local court or regulatory agency,
        or other governmental authority. Neither Seller nor Stockholders has
        received any notice of any of the above and no facts or circumstances
        exist which would, with the passage of time or giving of notice (or
        both), give rise to any of the above.

               (h) EMPLOYEES. Attached as Schedule 5.1(h) hereof is a complete
        list of all employees of Seller and their respective rates of
        compensation (including a breakdown of the portion thereof attributable
        to salary, bonus and other compensation, respectively) as of the date of
        Closing. Each employee is an employee at will and there are no
        collective bargaining agreements affecting any employee of Seller. Buyer
        shall not be obligated to hire any of Seller's employees.

        5.1(i) is an accurate and complete list of all agreements of any kind
        between Seller and its employees or group of employees, including,
        without limitation, employment agreements, collective bargaining
        agreements and benefit plans. Buyer shall not, by the execution and
        delivery of this Agreement or otherwise, become obligated to or assume
        any liabilities or contractual obligations with respect to any employee
        of Seller or otherwise become liable
<PAGE>
        for or obligated in any manner (contractual or otherwise) to any
        employee of Seller, including, without limiting the generality of the
        foregoing, any liability or obligation pursuant to any collective
        bargaining agreement, employment agreement, or pension, profit sharing
        or other employee benefit plan (within the meaning of Section 3(3) of
        the Employment Retirement Income Security Act of 1974, as amended) or
        any other fringe benefit program maintained by Seller or to which Seller
        contributes or any liability for the withdrawal or partial withdrawal
        from or termination of any such plan or program by Seller.

               (j) FINANCIAL STATEMENTS. Attached hereto as Schedule 5.1(j) are
        copies of Seller's balance sheet as of December 31, 1997, and a
        statement of income, cash flow and retained earnings for the year ended
        December 31, 1997, and Seller's balance sheet as of February 28, 1998
        (the "Balance Sheet Date"), and a statement of income, cash flow and
        retained earnings for the two-month period then ended (the "Financial
        Statements"). The Financial Statements (including any footnotes thereto)

        basis throughout the periods indicated. The Financial Statements
        (including all footnotes thereto) are true, complete and correct and
        present fairly the financial condition and the results of the operations
        of Seller for the period indicated thereon. All reserves for contingent
        risks have been estimated in accordance with GAAP and are appropriate
        and sufficient to cover all costs reasonably expected to be incurred
        from such risks. The Financial Statements are consistent with the books
        and records of Seller (which books and records are correct and complete.

               (k) TAXES. No federal, state, local or other tax returns or
        reports filed by Seller (whether filed prior to, on or after the date
        hereof) with respect to the Business or the Assets will result in any
        taxes, assessments, fees or other governmental charges upon the Assets
        or Buyer, whether as a transferee of the Assets or otherwise. All
        federal, state and local taxes due and payable with respect to the
        Business or the Assets have been paid, including, without limiting the
        generality of the foregoing, all federal, state and local income, sales,

                (l) HAZARDOUS MATERIALS. Neither Seller nor Shareholder has ever
        generated, transported, stored, handled recycled, reclaimed, disposed
        of, or contracted for the disposal of, hazardous materials, hazardous
        wastes, hazardous substances, toxic wastes or substances, infectious or
        medical waste, radioactive waste or sewage sludges as those terms are
        defined by the Comprehensive Environmental Response, Compensation and
        Liability Act of 1980 ("CERCLA"); the Atomic Energy Act of 1954; the
        Toxic Substances Control Act; the Occupational Health and Safety Act;
        any comparable or similar Texas statute; or the rules and regulations
        promulgated under any of the foregoing, as each of the foregoing may
        have been from time to time amended (collectively, "Hazardous
        Materials"). Seller has never owned, operated, had an interest in,
        engaged in and/or leased a waste transfer, recycling, treatment, storage
        or disposal facility, business or activity other than the Business.
        Seller has obtained and maintained all necessary trip tickets, signed by
        the applicable waste generators, and other records demonstrating the
        nature of the waste transported in connection with the Business. No
        employee, contractor or agent of Seller has, in the course and scope of
        employment with Seller, been harmed by exposure to Hazardous Materials.
        Seller has no direct or contingent liability or obligation for or in
        connection with any claimed release, discharge or leak of any substance
        onto any property or into the environment. Further, no portion of the
        facilities operated by Seller is listed on the CERCLA list or the
        National Priorities List of Hazardous Waste Sites or any similar list
        maintained by the State of Texas. Attached hereto as Schedule 5.1(l) is
        a complete list of the names and addresses of all disposal sites at any
        time now or in the past utilized by Seller, none of which sites is
        listed on the CERCLA list or the National Priorities List of Hazardous
        Waste Sites or any comparable Texas list. Neither Seller nor Shareholder
        is listed as a potentially responsible party under CERCLA or any
        comparable or similar state statute; neither Seller nor Shareholder has
        received any notice of such a listing; and neither Seller nor
        Shareholder knows of any facts or circumstances which could give rise to
        such a listing.
<PAGE>
               (m) GOVERNMENT NOTICES. Seller has delivered to Buyer, a
        description and copies, as of the date of this Agreement, of all
        notifications, filed or submitted, or required to be filed or submitted,
        to governmental agencies and of all material notifications from such
        governmental agencies relating to Seller and the Assets or relating to
        the discharge or release of materials into the environment or otherwise
        relating to the protection of the public health or the environment.

               (n) ABSENCE OF PRICE RENEGOTIATION CONTRACTS. Seller is not now
        nor has ever been a party to any governmental contracts subject to price
        redetermination or renegotiation.

               (o) GROSS REVENUES. The gross revenues generated by the Business
        for the 12- month period ending December 31, 1997 were $1,587,203.93.

               (p) COMPLETENESS OF DISCLOSURE. This Agreement and the Schedules
        hereto and all other documents and information furnished to Buyer and
        its representatives pursuant hereto do not and will not include any
        untrue statement of a material fact or omit to state a material fact
        necessary to make the statements therein not misleading. If Seller or
        Shareholder become aware of any fact or circumstance which would change
        a representation or warranty of Seller or Shareholder in this Agreement,
        the party with such knowledge shall immediately give notice of such fact
        or circumstance to Buyer. However, such notification shall not relieve
        Seller or Shareholder of their obligations under this Agreement, and at
        the sole option of Buyer, the truth and accuracy of any and all
        warranties and representations of Seller and Shareholder at the date of
        this Agreement shall be a precondition to the consummation of this
        transaction.

               SECTION 5.2 SURVIVAL. Each of the representations and warranties
        set forth in this Article V shall survive the Closing and the transfer
        of the Assets.

        SECTION 6.1 Buyer and Parent represent and warrant to Seller and
Shareholder that:

        (a) CORPORATE ORGANIZATION. Buyer is a corporation duly organized,
validly existing and in good standing under the laws of the State of Texas.
Parent is a corporation duly organized, validly existing and in good standing
under the laws of the State of Delaware.

        (b) AUTHORIZATION. Buyer and Parent each have all requisite corporate
power and corporate authority to enter into this Agreement, perform its
respective obligations hereunder and consummate the transactions contemplated
hereby. The execution and delivery of this Agreement, the consummation of the
transactions contemplated hereby and the compliance by Buyer and Parent with the
terms of this Agreement do not and will not conflict with or result in a breach
of any terms of, or constitute a default under, Buyer's Articles of
Incorporation or Bylaws or any other agreement or instrument to which Buyer or
Parent is a party or by which Buyer or Parent is bound. All necessary corporate
action has been taken by Buyer and Parent with respect to the execution and
delivery of this Agreement, and this Agreement constitutes a valid obligation of
Buyer and Parent enforceable in accordance with its terms except as limited by
bankruptcy, insolvency, reorganization or other such laws concerning the rights
of creditors.

        (c) PARENT STOCK. The Parent Stock to be delivered to Seller in
connection with this Agreement, when delivered in accordance with the terms of
this Agreement, will constitute valid and legally issued shares, fully paid and
nonassessable, and will be registered and free from any restriction on transfer
other than restrictions imposed by the Securities Act of 1993, as amended, or
the regulations promulgated thereunder.

        SECTION 6.2 SURVIVAL. Each of the representations and warranties set
forth in this Article VI shall survive the Closing and the transfer of the
Assets.

                                 NONCOMPETITION

        SECTION 7.1 NONCOMPETITION COVENANTS. Seller and Shareholder, jointly
and severally, agree that for a period of ten years following the date of
Closing, neither of them shall directly or indirectly, through a subsidiary or
affiliate (including without limitation, Betts Environmental or any of its
successors or assigns), without the prior express written consent of Buyer:

               (i) engage, whether as a corporation on its own account, or as an
        officer, director, shareholder, owner, partner, joint venturer,
        investor, agent, or in a managerial capacity, whether as an employee,
        independent contractor, consultant or advisor, or as a sales
        representative, in the business of: siting, developing, constructing,
        permitting or operating a facility for the processing, treatment or
        disposal of non-hazardous liquid waste (including, without limitation,
        waste oil, waste water, grease trap waste, grit trap waste and oil
        contaminated water); siting, developing, constructing, permitting or
        operating a facility for the processing, treatment and disposal of
        non-hazardous oilfield waste (including, without limitation, chlorides,
        heavy metals, cuttings, contaminated soils, drilling fluids and pit
        sludges); and transportation or collection of any such materials, in
        each case within the states of Texas, Louisiana and Arkansas (the
        "Territory");

               (ii) call upon any person who is, at that time, within the
        Territory, an employee of Buyer in a managerial capacity for the purpose
        or with the intent of enticing such employee away from or out of the
        employ of Buyer;

               (iii) call upon any person or entity which is, at that time, or
        which has been, within two years prior to that time, a customer of
        Seller or Buyer, as the case may be, within the Territory for the
        purpose of: siting, developing, constructing, permitting or operating a
        facility for the processing, treatment or disposal of non-hazardous
        liquid waste (including, without limitation, waste oil, waste water,
        grease trap waste, grit trap waste and oil contaminated water); siting,
        developing, constructing, permitting or operating a facility for the
        processing, treatment and disposal of non-hazardous oilfield waste
        including, without limitation, chlorides, heavy metals, cuttings,
        contaminated soils, drilling fluids and pit sludges); and transportation
        or collection of any such materials, in each case within the Territory;

               (iv) call upon any prospective acquisition candidate, on their
        own behalf or on behalf of any competitor, which candidate was either
        called upon by Seller or Shareholder or for which Seller or Shareholder
        made an acquisition analysis for Seller or Buyer;

               (v) disclose the identity of Buyer's customers, whether in
        existence or proposed, to any person, firm, partnership, corporation or
        business for any reason or purpose whatsoever; or

               (vi) promote or assist, financially or otherwise (including,
        without limitation, lending, guaranteeing loans or otherwise providing
        financial assurance in any way), any person, firm, partnership,
        corporation or other entity whatsoever to do any of the above.

        Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit Seller or Shareholder from (i) continuing to carry on its current
sludge de-watering operations from its present location and providing services
of a nature currently provided to clean water plants and publicly operated
treatment works, or (ii) acquiring as an investment not more than one percent of
the capital stock of a competing business, whose stock is traded on a national
securities exchange or over-the-counter.

        SECTION 7.2 INJUNCTIVE RELIEF. Because of the difficulty of measuring
economic losses 
<PAGE>
to Buyer as a result of the breach of the foregoing covenant, and because of the
immediate and irreparable damage that would be caused to Buyer for which it
would have no other adequate remedy, Seller and Shareholder agree that, in the
event of breach by any of them of the foregoing covenant, the covenant may be
enforced by Buyer by, without limitation, injunctions and restraining orders.

        SECTION 7.3 REASONABLENESS OF COVENANTS. It is agreed by the parties
that the foregoing covenants in this Article VII impose a reasonable restraint
on Seller and Shareholder in light of the activities and business of the Buyer
on the date of the execution of this Agreement and future plans of the Buyer.

        SECTION 7.4 SEVERABILITY OF COVENANTS. The covenants in this Article VII
are severable and separate, and the unenforceability of any specific covenant
shall not affect the provisions of any other covenants. Moreover, in the event
any court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

        SECTION 7.5 INDEPENDENT COVENANTS. All of the covenants in this Article
VII shall be construed as an agreement independent of any other provision of
this Agreement, and the existence of any claim or cause of action of Seller or
Shareholder against Buyer, whether predicated on this Agreement or otherwise,
shall not constitute a defense to the enforcement by Buyer of such covenants. It
is specifically agreed that the duration of the noncompetition covenants stated
above shall be computed by excluding from such computation any time during which
Seller or Shareholder is in violation of any provision of this Article VII and
any time during which there is pending in any court of competent jurisdiction
any action (including any appeal from any judgment brought by any person,
whether or not a party to this Agreement, in which action Buyer seeks to enforce
the agreements and covenants of Seller or Shareholder or in which any person
contests the validity or such agreements and covenants or their enforceability
or seeks to avoid their performance or enforcement.

        SECTION 7.6 MATERIALITY. Seller and Shareholder hereby agree that the
foregoing noncompetition covenants are a material and substantial part of this
transaction.

                                  ARTICLE VIII

                 NON-ASSUMPTION OF LIABILITIES; INDEMNIFICATION

        SECTION 8 NON-ASSUMPTION OF LIABILITIES. Except as explicitly set forth

Agreement or otherwise, assume, become responsible for or incur any liability or
obligation of any nature of Seller or Shareholder whether legal or equitable,
matured or contingent, known or unknown, foreseen or unforeseen, ordinary or
extraordinary, patent or latent, whether arising out of occurrences prior to, at
or after the date of this Agreement, including, without limiting the generality
of the foregoing, any liability or obligation arising out of or relating to: (a)
any occurrence or circumstance (whether known or unknown) which occurs or exists

lapse of time or giving notice (or both) would constitute, a breach or default
under any lease, contract, or other instrument or agreement whether written or
oral); (b) any injury to or death of any person or damage to or destruction of
any property, whether based on negligence, breach of warranty, or any other
theory; (c) a violation of the requirements of any governmental authority or of
the rights of any third person, including, without limitation, any requirements
relating to the reporting and payment of federal, state, local or other income,
sales, use, franchise, excise or property tax liabilities of Seller or
Shareholder; (d) the generation, collection, transportation, storage or disposal
by Seller or Shareholder of any materials, including, without limitation,
hazardous materials; (e) an agreement or arrangement between Seller and the
employees of Seller or Shareholder or any labor or collective bargaining unit
representing any such employees; (f) the severance pay obligation of Seller or
any employee benefit plan (within the meaning of Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended) or any other fringe benefit
program maintained or sponsored by Seller or Shareholder 
<PAGE>

liabilities therefor or any liability for the withdrawal or partial withdrawal

contemplated hereunder. Seller and Shareholder each agree to indemnify Buyer,
its successors and assigns from and against all of the above liabilities and
obligations in accordance with Section 8.3 below.

        SECTION 8.2 ASSUMPTION OF SPECIFIC LIABILITIES. In addition to the
payment of the Assumed Debt, Buyer agrees to perform all of Seller's contractual
obligations related to the Customer Contracts to the extent, and only to the
extent, such obligations first mature and are required to be performed after the
close of business on the Closing Date.

        SECTION 8.3 INDEMNIFICATION BY SELLER AND SHAREHOLDER. Notwithstanding
investigation at any time made by or on behalf of Buyer, Seller and Shareholder,
jointly and severally, agree to defend, indemnify and hold harmless Buyer, its
officers, shareholders, directors, divisions, subdivisions affiliates, parent,
employees, agents, successors, assigns and the Assets from and against all
losses, claims, actions, causes of action, damages, liabilities, expenses and
other costs of any kind or amount whatsoever (including, without limitation,
reasonable attorneys' fees), whether equitable or legal, matured or contingent,
known or unknown, foreseen or unforeseen, ordinary or extraordinary, patent or
latent, which result, either before or after the date of this Agreement, from:

               (b) breach of any representation or warranty under this Agreement
        by Seller or Shareholder;

               (d) liability of Seller or Shareholder imposed upon Buyer
        (including, without limitation, all liability for the generation,

        disclosed on Schedule 5.1(l) hereof);

        Agreement;

               (f) failure of Seller or Shareholder to obtain consent to a

        Shareholder which is imposed on Buyer whether as a result of bankruptcy
        proceedings or otherwise and whether as a result of bankruptcy
        proceedings or otherwise and whether as an account payable by Seller or
        Shareholder or as a claim of alleged fraudulent conveyance or
        preferential payments within the meaning of the United States Bankruptcy

        and

               (l) any claim by a third party that, if true, would mean that a
        condition for indemnification set forth in this Section 8.3 had been
        satisfied.

Buyer shall be deemed to have suffered such loss, claim, action, cause of
action, damage, liability, expense or other cost, or to have paid or to have
become obligated to pay any sum on account, of, the matters referred to in
subparagraphs (a) - (l) of this Section 8.3 if the same shall be suffered, paid
or incurred by Buyer or any parent, subsidiary, affiliate, or successor of
Buyer. The amount of the loss, claim, action, cause of action, damage,
liability, expense or other cost deemed to be suffered, paid or incurred by
Buyer shall be an amount equal to the loss, claim, action, cause of action,
damage, liability, expense or other cost suffered, aid or incurred by such
parent, subsidiary, affiliate, or successor.

        SECTION 8.4 PROCEDURE FOR INDEMNIFICATION. Promptly after a party hereto
(hereinafter the "Indemnified Party") has received notice of or has knowledge of
any claim by a person not a party to this Agreement ("Third Person" or the
commencement of any action or proceeding by a Third Person, the Indemnified
Party shall, as a condition precedent to a claim with respect thereto being made
against any party obligated to provide indemnification pursuant to this
Agreement (hereinafter the "Indemnifying Party"), give the Indemnifying Party
written notice of such claim or the commencement of such action or proceeding
(the "Notice"). The Notices shall state the nature and the basis of such claim
and a reasonable estimate of the amount thereof. The Indemnifying Party, after
receipt of the Notice, shall defend and settle, at its own expense and by its
own counsel, each such matter so long as the Indemnifying Party pursues the same
diligently and in good faith and the claim does not involve injunction or
equitable relief or involve criminal penalties. The Indemnified Party shall
cooperate with the Indemnifying Party and its counsel in the defense thereof and
in any settlement thereof. Such cooperation shall include, but shall not be
limited to, furnishing the Indemnifying Party with any books, records or
information reasonably requested by the Indemnifying Party that are in the
Indemnified Party's possession or control. Notwithstanding the foregoing, the
Indemnified Party shall have the right to participate in any matter through
counsel of its own choosing at its own expense, provided that the Indemnifying
Party's counsel shall always be lead counsel and shall determine all litigation
and settlement steps, strategy and the like. After the Indemnifying Party has
received the Notice, the Indemnifying Party shall not be liable for any
additional legal expenses incurred by the Indemnified Party in connection with
any defense or settlement of such asserted liability, except to the extent such
participation is requested by the Indemnifying Party, in which event the
Indemnified Party shall be reimbursed by the Indemnifying Party for reasonable
additional legal expenses, out-of-pocket and allocable share of employee
compensation incurred in connection with such participation for any employee
whose participation is so requested. The foregoing notwithstanding, if the
Indemnifying Party fails diligently to defend any such matter to which the
Indemnified Party is entitled to indemnification hereunder or if the claim
involves criminal penalties, the Indemnified Party may undertake such defense
through counsel of its choice and at the Indemnifying Party's expense. In each
case where the Indemnifying Party is obligated to pay the costs and expenses of
the Indemnified Party, the Indemnifying Party shall pay the costs and expenses
of the Indemnified Party as such costs and expenses are incurred. If the
Indemnifying Party desires to accept a final and complete settlement of any such
Third Person claim and the Indemnified Party refuses to consent to such
settlement, then the Indemnifying Party's liability under this Section with
respect to such Third Person claim shall be limited to the amount so offered in
settlement by said Third Person and the Indemnified Party shall reimburse the
Indemnifying Party for any additional costs of defense which it subsequently
incurs with respect to such claim.

hereunder, and in the case of contracts and rights, if any, which cannot be
transferred effectively without the consents of third parties, to endeavor to
obtain such consents promptly, and if any be unobtainable, to use their best
efforts to provide Buyer with the benefits thereof in some other manner. Seller
and Shareholder will cooperate and use their best efforts to have the present
officers, directors and employees of Seller cooperate with Buyer on and after
the Closing in furnishing information, evidence, testimony and other assistance
in connection with any actions, proceedings, arrangements or disputes of any
nature with respect to matters pertaining to all periods prior to Closing.

        SECTION 10.2 JOINT AND SEVERAL OBLIGATIONS. All representations,
warranties and agreements of Seller or Shareholder under this Agreement, the

        SECTION 10.3 WAIVER. Except as otherwise provided herein, no delay of or
omission in the exercise of any right, power or remedy accruing to any party as
a result of any breach or default by any other party under this Agreement shall
impair any such right, power or remedy, nor shall it be construed as a waiver of
or acquiescence in any such breach or default, or of or in any similar breach or
default occurring later; nor shall any waiver of any single breach or default be
deemed a waiver of any other breach or default occurring before or after that
waiver.

        SECTION 10.4 TIME OF THE ESSENCE. Time is of the essence of this
Agreement.

affiliate, without the prior express written consent of Buyer:

      (i) engage, whether as a corporation on its own account, or as an officer,
director, shareholder, owner, partner, joint venturer, investor, agent, or in a
managerial capacity, whether as an employee, independent contractor, consultant
or advisor, or as a sales representative, in the business of: siting,
developing, permitting or operating a business of transport and disposal of
nonhazardous liquid waste (including, without limitation, waste oil, waste

water) ; and transportation or collection of any such materials, in each case
within a radius of 100 air miles of Braintree, Massachusetts (the "Territory");

      (ii) call upon any person who is, at that time, within the Territory, an
employee of Buyer in a managerial capacity for the purpose or with the intent of
enticing such employee away from or out of the employ of Buyer;

      (iii) call upon any person or entity which is, at that time, or which has
been, within one year prior to that time, a customer of Seller or Buyer, as the
case may be, within the Territory for the purpose of the business of transport
and disposal of non-hazardous liquid waste (including, without limitation, waste

prohibit Seller or Stockholder from acquiring as n investment not more than one
percent of the capital stock of a competing business, whose stock is traded on a
national securities exchange or over-the-counter.

      SECTION 5.2 INJUNCTIVE RELIEF. Because of the difficulty of measuring
economic losses to Buyer as a result of the breach of the foregoing covenant,
and because of the immediate and irreparable damage that would be caused to

agree that, in the event of breach by any of them of the foregoing covenant, the
covenant may be enforced by Buyer by, without limitation, injunctions and
restraining orders.

the foregoing covenants in this Section 5 impose a reasonable restraint on
Seller and Stockholder in light of the activities and business of the Buyer on
the date of the execution of this Agreement and the future plans of the Buyer.

      SECTION 5.4 SEVERABILITY OF COVENANTS. The covenants in this Section 5 are
severable and separate, and the unenforceability of any specific covenant shall
not affect the provisions of any other covenant. Moreover, in the event any
court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

      SECTION 5.5 INDEPENDENT COVENANTS. All of the covenants in this Section 5
shall be construed as an agreement independent of any other provision of this
Agreement. Said covenants shall be effective as of the Closing Date and upon
payment of the agreed Purchase Price to Seller. It is specifically agreed that
the duration of the noncompetition covenants stated above shall be computed by
excluding from such computation any time during which Seller or Stockholder is
in violation of any provision of this Section 5 and any time during which there
is pending in any court of competent jurisdiction any action (including any
appeal from any judgment) brought by any person, whether or not a party to this
Agreement, in which action Buyer seeks to enforce the agreements and covenants
of Seller or Stockholder or in which any person contests the validity of such
agreements and covenants or their enforceability or seeks to avoid further
performance or enforcement.

           AND REPRESENTATIONS OF SELLER AND COVENANTS OF SELLER.

     6.1 TERMS OF INDEMNIFICATION. Seller and Stockholder, jointly and
severally, (the "Indemnitors") agree to indemnify and hold harmless Buyer, its
officers, directors, employees, agents, successors and assigns, and the assets
from and against any and all damages resulting from any breach of any
representation, warranty, covenant or agreement of Seller set forth in this
Agreement. The Indemnitors further agree to indemnify and hold harmless Buyer,
its officers, directors, employees, agents, successors and assigns, from and
against any and all debts, liabilities, choses in action, or claims of any
nature, absolute or contingent, resulting from any such breach, (collectively,
"claims"). For any claims with respect to any taxes of any type or nature
whatsoever owed to any federal, state or local government or agency thereof, or
any interest or penalties with respect thereto, this indemnity shall survive the
Closing for the period of the statute of limitations applicable to any such
taxes, interest or penalty. For all claims, this indemnity shall survive the
Closing for a period of two (2) years. The Indemnitors shall pay to Buyer any
amounts due Buyer from the Indemnitors pursuant to the terms of this section
within thirty (30) days after demand therefor by Buyer.

      6.2 NOTICE OF CLAIMS. Buyer shall give prompt written notice to Seller of
the assertion of any claim, the amount of which together with any anticipated
expenses of defense, settlement or investigation, Buyer reasonably expects to
exceed Two Hundred Fifty and 00/100 Dollars ($250.00). Seller may, by written
notice to Buyer, received by Buyer

                                    17
<PAGE>
within ten (10) days after receipt by Seller of the original notice from Buyer,
assume the defense of any such claim with counsel satisfactory to Buyer. If
Seller has assumed the defense of a claim, Buyer shall have the right, but not
the obligation, to participate at its own expense in the defense of, or in any
negotiation with respect to, such claim. If Seller does not assume the defense
of a claim under this Section 6 within ten (10) days after receipt of notice
from Buyer of such claim, the Indemnitors shall be obligated to pay all the
reasonable fees and expenses incurred by Buyer in any defense, settlement or
compromise of such claim and Buyer shall have the right to control the defense.
In all events, no settlement or compromise of any claim, the defense of which
Seller has the right to assume hereunder, shall be made in any event without the
consent of Seller. Any such consent shall not be unreasonably withheld or
delayed; provided, however, that in the event Seller shall refuse to join in any
such settlement or compromise, Buyer shall have the right to deposit with Seller
the settlement amount and Seller shall assume the defense of the claim at its
expense and become solely liable therefor. Delay on the part of Buyer in giving
notice of a claim for which indemnification is sought shall reduce the liability
of the Indemnitors under this Section 6 only to the extent that the Indemnitors
was demonstrably and materially prejudiced by such delay in notice.

            part of the consideration for an acquisition by the Company of
            assets or securities of a third party, provided that the acquisition
            is approved by the Board of Directors of the Company or a duly
