PART I

ITEM 1. BUSINESS

OVERVIEW

         OHM Corporation, an Ohio corporation, and its predecessors (the
"Company"), is one of the largest providers of technology-based, on- site
hazardous waste remediation services in the United States. The Company has been
in the environmental services business since 1969. The Company has successfully
completed approximately 31,000 projects involving contaminated groundwater, soil
and facilities.

         The Company provides a wide range of environmental services, primarily
to government agencies and to large chemical, petroleum, transportation and
industrial companies. The Company has worked for the United States Environmental
Protection Agency ("EPA"), the Department of Defense ("DOD") (including the U.S.
Army Corps of Engineers ("USACE") and the U.S. Departments of the Air Force,
Army and Navy), the Department of Energy ("DOE"), a number of state and local
governments and a majority of the Fortune 100 industrial and service companies.
In addition to its technology-based, on-site remediation services, the Company
also offers a broad range of other services, including site assessment,
engineering, remedial design and analytical testing. Service is provided through
30 regional offices, one fixed laboratory at its headquarters in Findlay, Ohio,
eight mobile laboratories, and approximately 2,800 pieces of mobile treatment
and related field equipment.

         Since the disposition by the Company in early 1993 of its interest in
OHM Resource Recovery Corp., the operator of a hazardous waste treatment and
disposal facility, the Company does not own or operate any hazardous waste
disposal sites or other off-site waste treatment or disposal facilities. The
Company generally coordinates through licensed subcontractors the transportation
and disposal of any hazardous waste which is not remediated on-site.

         On May 30, 1995, pursuant to an Agreement and Plan of Reorganization,
the Company through its wholly-owned subsidiary, OHM Remediation Services Corp.
("OHMR"), acquired (the "Acquisition") in exchange for 9,668,000 shares of
Common Stock of the Company, par value $.10 per share ("Common Stock"),
substantially all of the assets and certain liabilities of the environmental
remediation services business of Rust International Inc. ("Rust"), a
majority-owned subsidiary of WMX Technologies, Inc. ("WMX"). In connection with
the Acquisition, the Company and WMX entered into a Guarantee Agreement whereby
in exchange for a warrant exercisable for five years, to purchase 700,000 shares
of Common Stock at a price per share of $15.00, WMX agreed, until May 30, 2000,
to guarantee indebtedness of the Company in an amount not to exceed $62,000,000
which will increase proportionately up to $75,000,000 upon issuance of shares
under the warrant. In addition, the Company entered into a Standstill and
Non-competition Agreement (the "Standstill Agreement") with WMX and its
affiliates. As contemplated by the Standstill Agreement, three designees of WMX
were elected to the Board of Directors of the Company.

         The Company also has an approximately 40% interest in NSC Corporation
("NSC"), a provider of asbestos abatement and specialty contracting services.

OHM'S ENVIRONMENTAL REMEDIATION SERVICES

         The Company assists its clients by providing comprehensive on-site
treatment of toxic materials and hazardous wastes. By applying a broad range of
biological, chemical, physical, soil vapor extraction and thermal treatment
technologies, the Company performs on-site treatment and remediation services
for the control, detoxification, decontamination, and volume reduction of
hazardous and toxic material. Accordingly, the Company has designed a wide range
of modular mobile treatment equipment, which can be used on-site, either
independently or in a system, for removing, detoxifying, reducing the volume of,
or stabilizing contaminants. This equipment includes thermal destruction units,
dewatering presses, filters, separators, ion exchangers, stripping systems and
mobile process equipment which apply various physical, chemical and biological
technologies to remediate contaminants. Since 1970, the Company has completed
approximately 31,000 projects throughout the United States, cleaning up
hazardous wastes, removing toxic chemicals from groundwater and cleaning
facilities of contaminants.

         The Company endeavors to offer clients an increasingly broad array of
on-site treatment services, either on a planned or emergency basis, from its 30
regional offices located throughout the country. On-site environmental
remediation services provided by the Company include:

         *        Treatment, stabilization or removal of contaminants;

         *        Decontamination of industrial facilities;

                                        1


<PAGE>   4



         *        Assessment, characterization and treatment of contaminated
                  soil and/or groundwater;

         *        Surface impoundment restoration, including volume reduction,
                  stabilization and closure of contaminated lagoons;

         *        Management of underground and above ground storage tanks;

         *        Design, engineering, fabrication, installation and operation
                  of on-site treatment equipment; and

         *        Emergency response to virtually any kind of industrial or
                  transportation-related accident involving hazardous waste or
                  materials.

         The Company undertakes these projects on both a planned basis, which is
scheduled in advance, and an emergency basis, which is performed in direct
response to spills, fires and industrial accidents. The Company places its
emphasis upon planned work because of its more predictable resource
requirements, and because of its larger potential market. In 1996, planned
projects accounted for approximately 98% of the Company's revenue.

         The Company believes that professional project management and cost
accounting systems are key factors in ensuring that projects are accurately and
successfully completed on time and within prescribed cost estimates. The
Company's project management structure combines the various functional areas
performing work at the project, including technical, engineering, administrative
and accounting specialists, into a coordinated team, reporting directly to the
project manager. The project manager's responsibility for scheduling and project
completion allows technical and operations specialists to operate efficiently
with fewer distractions.

         The Company also believes that professional project management is a
critical element in limiting the significant risks and potential liabilities
involved in environmental remediation projects due to the presence of hazardous
and toxic substances. The Company has adopted a number of risk management
policies and practices including special employee training and health monitoring
programs. The Company's health and safety staff establish a safety plan for each
project prior to the initiation of work, monitor compliance with the plan and
administer the Company's medical monitoring program to staff involved. The
Company believes that it has an excellent overall health and safety record.

TREATMENT TECHNOLOGIES

         Designing, developing and implementing solutions to environmental
hazards requires an interdisciplinary approach combining practical field
experience with remediation processes and technical skills in fields such as
chemistry, microbiology, hydrogeology, fluid mechanics, thermodynamics, and
geotechnical, biochemical and process engineering. The Company employs
scientific and engineering professionals in the environmental services field who
enhance the Company's ability to effectively participate in larger, more
technically complex remediation projects.

         The Company has significant experience in the commercialization and
practical field application of new and existing technologies for the treatment
of hazardous wastes, with emphasis on the further development and application of
existing technologies. To provide direct support for its efforts to place
innovative technology in the field, in 1973, the Company built its own equipment
fabrication facility; in 1978, the Company built a laboratory dedicated to
developing commercial applications of biological treatment of hazardous wastes;
and in 1993, the Company built a treatability laboratory to support testing and
enhancement of a broad range of innovative technology applications. The Company
also provides technology development services under contract to its clients.

         The following represent the principal technologies used by the Company
for remediation projects:

         *        BIOLOGICAL REMEDIATION: The Company's Bioremediation
                  Department designs and tests bioremediation techniques for
                  treating hazardous waste. Biological treatment technologies
                  generally utilize enhanced microbiological activity to
                  decompose and detoxify contaminants, often using a site's
                  natural flora to remediate a problem. The Company's biological
                  laboratories can "feed" the microorganisms, that destroy the
                  pollutant, so that they grow at a faster rate than would occur
                  in nature. The Company has developed considerable expertise in
                  transferring innovative bioremediation techniques from the
                  laboratory to the field. The Company utilizes the following
                  biological treatment technologies:

                                        2


<PAGE>   5




                           Anaerobic Digestion Vessel -- degradation of organic
                           contaminants in the absence of air.

                           Trickling Filters -- secondary treatment on
                           large-scale treatment applications to enhance the
                           oxygenation process.

                           Activated Sludge Reactor -- treatment utilizing
                           holding tanks to enhance biological degradation.

                           Submerged Fixed Reactor Vessel -- combines a
                           trickling filter and an activated sludge reactor for
                           more efficient degradation of contaminants.

                           Aeration Lagoons -- secondary or tertiary treatment
                           to remove carbon, nitrogen or phosphorous.

         *        CHEMICAL TREATMENT: The Company's mobile chemical treatment 
                  equipment utilizes the following technologies:

                           Carbon Adsorption -- passage of a liquid or vapor
                           discharge stream through a bed of activated carbon
                           which adsorbs certain contaminants.

                           Oxidation/Reduction -- conversion of complex
                           components of the wastestream into simpler, less
                           toxic materials through addition of oxidizing or
                           reducing agents such as ozone, hydrogen peroxide and
                           sodium bisulfate.

                           Clarification/Flocculation -- addition of chemicals
                           which bond or interact with suspended solids and
                           dissolved contaminants to form a flocculated product
                           which can be separated through settling or filtration
                           techniques.

                           Ion-Exchange -- ion-exchange resins used for the
                           selective removal of heavy metals and hazardous ions.

                           Ultraviolet Treatment -- use of ultraviolet light to
                           kill pathogens and convert or degrade some organic
                           chemicals, especially when combined with the use of
                           oxidants.

         *        PHYSICAL TREATMENT: The Company's physical treatment
                  technologies generally involve removal of contaminants through
                  osmosis, settlement or filtration. The Company's mobile
                  physical treatment equipment utilizes the following
                  technologies:

                           Heated Volatile Stripping -- removal of contaminants
                           with low boiling points by passage of air under
                           pressure through the wastestream.

                           Fume Scrubbing -- passage of a vaporized stream
                           through an aerosol spray to remove contaminant
                           particles from the vapor stream.

                           Immiscible Fraction Separation -- removal of a
                           component of a wastestream which is immiscible in
                           water through settling techniques.

                           Mixed Media Filtration -- removal of suspended
                           particles by passage through selected filter media.

         *        SOIL VAPOR EXTRACTION AND SOIL FLUSHING: The Company has
                  applied several innovative technologies, known generally as
                  soil vapor extraction and soil flushing, based on a patent
                  granted in 1984 for a portable method of soil decontamination
                  above or below the groundwater table. The technologies
                  generally involve the use of a system of pressurized injection
                  and vacuum extraction wells to induce a pressure gradient and
                  a fluid flow to extract contaminants and treat them in-situ or
                  in an aboveground system. The technologies can be used to
                  remove contaminants in soils and groundwater, in-situ or
                  ex-situ, and can be combined with bioremediation to treat
                  mixtures of volatile and non-volatile contaminants.

         *        THERMAL TREATMENT: The Company's thermal treatment
                  technologies include infrared incineration, rotary kiln
                  technology and thermal desorption. Infrared incineration uses
                  electric powered resistance heaters as a source of radiant
                  heat for removal and destruction of hazardous organic
                  contaminants. Rotary kiln incineration is the traditional
                  incineration process for destroying organic hazardous waste
                  constituents in a refractory lined rotating

                                        3


<PAGE>   6



                  kiln. Thermal desorption is a thermal treatment technology
                  which uses heat to remove volatile compounds from a waste
                  without oxidation of the compounds. The Company has
                  established a thermal treatment engineering group to assess,
                  develop and commercialize thermal technologies for on-site
                  remediation.

FOCUS ON LARGER PROJECTS AND GOVERNMENT CONTRACTS

         The Company pursues larger projects and term contracts as a method to
achieve more predictable revenue, more consistent utilization of equipment and
personnel, and greater leverage of sales and marketing costs. Historically, the
Company relied most heavily on private sector remediation projects in the
Northeast and Midwest that typically involved planned cleanups of sites that
were contaminated in the normal course of manufacturing activity and emergency
cleanups of oil or chemical spills. Contract values typically were less than $1
million in size and less than one year in duration. The Company now targets more
complex, multi-million dollar, multi-year private sector and government
site-specific and term contracts. As a result of its shift in project focus,
since the beginning of 1991 the Company has been awarded a large number of
multi-million dollar government term contracts which, in some cases, may require
several years to complete. Although the Company still performs private sector
remediation projects, the Company currently derives a majority of its revenue
from government term contracts and these larger projects. Larger site-specific
projects impose heightened risks of loss in the event that actual costs are
higher than those estimated at the time of bid due to unanticipated problems,
inefficient project management, or disputes over the terms and specifications of
the contracted performance.

         Since the beginning of 1991, the Company has been awarded 30 government
term contracts, and several large projects, including those acquired by the
Company in connection with the Acquisition, with potential values ranging from
$10 million to $250 million and terms ranging from one to ten years. Such
government term contracts typically are performed by completing remediation work
under delivery orders, issued by the contracting government entity, for a large
number of small-to-medium-sized projects throughout the geographic area covered
by the contract. Such government term contracts do not represent commitments
with respect to the amount, if any, that will actually be expended pursuant to
such contracts, may generally be canceled, delayed or modified at the sole
option of the government, and are subject to annual funding limitations and
public sector budget constraints. Accordingly, such government contracts
represent the potential dollar value that may be expended under such contracts;
therefore, no assurance can be provided that such amounts, if any, will be
actually spent on any projects, or of the timing thereof.

         For the fiscal year ended December 31, 1996, 77% of the Company's
revenue was derived from federal, state and local government contracts. The
Company expects that the percentage of its revenue attributable to such
government clients will continue to represent a significant portion of its
revenue. In addition to its dependence on government contracts, the Company also
faces the risks associated with such contracting, which could include
substantial civil and criminal fines and penalties. As a result of its
government contracting business, the Company is, has been and may in the future
be subject to audits and investigations by government agencies. In addition to
potential damage to the Company's business reputation, the failure by the
Company to comply with the terms of any of its government contracts could also
result in the Company's suspension or debarment from future government contracts
for a significant period of time. The fines and penalties which could result
from noncompliance with appropriate standards and regulations, or the Company's
suspension or debarment, could have a material adverse effect on the Company's
business, particularly in light of the increasing importance to the Company of
work for various government agencies.

ENVIRONMENTAL CONTRACTOR RISKS

         Although the Company believes that it generally benefits from increased
environmental regulations, and from enforcement of those regulations, increased
regulation and enforcement also create significant risks for the Company. The
assessment, remediation, analysis, handling and management of hazardous or
radioactive substances necessarily involve significant risks, including the
possibility of damages or injuries caused by the escape of hazardous materials
into the environment, and the possibility of fines, penalties or other
regulatory action. These risks include potentially large civil and criminal
liabilities for violation of environmental laws and regulations, and liabilities
to customers and to third parties, including governmental agencies, for damages
arising from performing services for clients, which could have a material
adverse effect on the Company.

         Potential Liabilities Arising Out of Environmental Laws and
Regulations. All facets of the Company's business are conducted in the context
of a developing and changing statutory and regulatory framework. The Company's
operations and services are affected by and subject to regulation by a number of
federal agencies, including the EPA, the Occupational Safety

                                        4


<PAGE>   7



and Health Administration ("OSHA"), and in limited occasions, the Nuclear
Regulatory Commission, as well as applicable state and local regulatory
agencies. For a description of certain applicable laws and regulations, see
"Regulation."

         Potential Liabilities Involving Clients and Third Parties. In
performing services for its clients, the Company could potentially be liable for
breach of contract, personal injury, property damage and negligence, including
claims for lack of timely performance and/or for failure to deliver the service
promised (including improper or negligent performance or design, failure to meet
specifications and breaches of express or implied warranties). The damages
available to a client, should it prevail in its claims, are potentially large
and could include consequential damages.

         Environmental contractors, in connection with work performed for
clients, also potentially face liabilities to third parties from various claims,
including claims for property damage or personal injury stemming from a release
of hazardous substances or otherwise. Claims for damage to third parties could
arise in a number of ways, including through a sudden and accidental release or
discharge of contaminants or pollutants during the performance of services,
through the inability--despite reasonable care--of a remedial plan to contain or
correct an ongoing seepage or release of pollutants, through the inadvertent
exacerbation of an existing contamination problem, or through reliance on
reports prepared by the Company. Personal injury claims could arise
contemporaneously with performance of the work or long after completion of the
project as a result of alleged exposure to toxic substances. In addition,
increasing numbers of claimants assert that companies performing environmental
remediation should be held strictly liable (i.e., liable for damages regardless
of whether its services were performed using reasonable care) on the grounds
that such services involved "abnormally dangerous activities."

         Clients frequently attempt to shift various liabilities arising out of
remediation of their own environmental problems to contractors through
contractual indemnities. Such provisions seek to require the Company to assume
liabilities for damage or injury to third parties and property and for
environmental fines and penalties. The Company has adopted risk management
policies designed to address these problems, but cannot assure their adequacy.
In addition, the Company generally coordinates through subcontractors the
transportation of any hazardous waste which is not remediated on-site to a
licensed hazardous waste disposal or incineration facility.

         Moreover, during the past several years, the EPA and other governmental
agencies have constricted significantly the circumstances under which they will
indemnify contractors against liabilities incurred in connection with
remediation projects undertaken by contractors under contract with such
governmental agencies.

DEPENDENCE ON ENVIRONMENTAL REGULATION

         Much of the Company's business is generated either directly or
indirectly as a result of federal and state laws, regulations and programs
related to environmental issues. Accordingly, a reduction in the number or scope
of these laws, regulations and programs, or changes in government policies
regarding the funding, implementation or enforcement of such laws, regulations
and programs, could have a material adverse effect on the Company's business.
See "Regulation."

MARKETS AND CUSTOMERS

         The Company provides its services to a broad base of clients in both
the private and government sectors. Its private sector clients include large
chemical, petroleum, manufacturing, transportation, real estate, electronics,
automotive, aerospace and other industrial companies, as well as engineering and
consulting firms. The Company has worked for a majority of the Fortune 100
industrial companies. Historically, the majority of the Company's private sector
revenue was derived from projects with values typically less than $1 million in
size and less than one year in duration. Revenue from industrial clients for
1996 was $124.7 million and constituted 23% of the Company's revenue.

         In the government sector, the market for the Company's services
primarily consists of federal government agencies. The Company has been a prime
contractor to the EPA since 1984 under Emergency Response Cleanup Services
("ERCS") contracts administered under the Superfund Removal Program. In
addition, through site specific and term contracts, the Company provides its
services to the DOD, including USACE, the U.S. Departments of the Navy, Air
Force and Army, at DOE facilities and to state and local governments. Revenue
from government agencies in 1996 aggregated $426.3 million and accounted for 77%
of revenue, of which the Department of the Navy and the USACE accounted for
approximately $167.7 million or 30% and $127.1 million or 23% of revenue,
respectively.

                                        5


<PAGE>   8



SEASONALITY AND FLUCTUATION IN QUARTERLY RESULTS

         The timing of the Company's revenue is dependent on its backlog,
contract awards and the performance requirements of each contract. The Company's
revenue is also affected by the timing of its clients' planned remediation
activities which generally increase during the third and fourth quarters.
Because of this change in demand, the Company's quarterly revenue can fluctuate,
and revenue for the first and second quarters of each year has historically been
lower than for the third and fourth quarters. Although the Company believes that
the historical trend in quarterly revenue for the third and fourth quarters of
each year are generally higher than the first and second quarters, there can be
no assurance that this will occur in future periods. Accordingly, quarterly or
interim results should not be considered indicative of results to be expected
for any quarter or for the full year.

COMPETITION

         The environmental services industry is highly competitive with numerous
companies of various size, geographic presence and capabilities participating.
The Company believes that it has approximately a dozen principal competitors in
the environmental remediation sector of the environmental services industry and
numerous smaller competitors. The Company believes that the principal
competitive factors in its business are operational experience, technical
proficiency, breadth of services offered, local presence and price. In certain
aspects of the Company's environmental remediation business, substantial capital
investment is required for equipment. Certain of the Company's competitors have
greater financial resources, which could allow for greater investment in
equipment and provide better access to bonding and insurance markets to provide
the financial assurance instruments which are often required by clients.
Additionally, the relatively recent entry of several aerospace and defense
contractors, as well as large construction and engineering firms, into the
environmental services industry has increased the level of competition. The
Company believes that the demand for environmental services is still developing
and expanding and, as a result, many small and large firms will continue to be
attracted to the industry.

INSURANCE

         The Company maintains a comprehensive liability insurance program that
is structured to provide coverage for major and catastrophic losses while
essentially self-insuring losses that may occur in the ordinary course of
business. The Company contracts with primary and excess insurance carriers and
generally retains $250,000 to $500,000 of liability per occurrence through
deductible programs, self-insured retentions or through reinsurance provided by
a wholly-owned insurance captive which reinsures some of the Company's workers'
compensation risks.

         Although the Company believes its insurance program to be appropriate
for the management of its risks, its insurance policies may not fully cover
risks arising from the Company's operations. Policy coverage exclusions,
retaining risks through deductible and self-insured retention programs, or
losses in excess of the coverage may cause all or a portion of one or more
losses not to be covered by such insurance.

EMPLOYEES

         The Company had approximately 3,100 employees at December 31, 1996.
Approximately 30 employees of the Company were covered by collective bargaining
agreements. The Company considers relations with its employees to be
satisfactory.

PATENTS

         The Company currently owns two patents covering certain design features
of equipment employed in its on-site remediation business. The first relates to
a filtration system developed and used by the Company to remove pollutants from
flowing creeks and streams and the second, known as a Portable Method for
Decontaminating Earth, relates to a decontamination system used by the Company
to remove contaminants from the soil through a process, commonly known as soil
vapor extraction. The Company utilizes X*TRAX(R) and LT*X(R) to perform thermal
desorption services. The X*TRAX(R) and LT*X(R) systems are waste treatment
processes that thermally separate organic contaminants from soils or solids with
subsequent treatment of the organic vapor stream. Although the Company considers
its patents to be important, they are not a material factor in its business.

REGULATION

         The environmental services business, including the remediation services
segment of the industry, has benefited from extensive federal and state
regulation of environmental matters. On the other hand, the Company's
environmental services are also

                                        6


<PAGE>   9



subject to extensive federal and state legislation as well as regulation by the
EPA, the OSHA and applicable state and local regulatory agencies. All facets of
the Company's business are conducted in the context of a rapidly developing and
changing statutory and regulatory framework and an aggressive enforcement and
regulatory posture. The full impact of these laws and regulations, and the
enforcement thereof, on the Company's business is difficult to predict,
principally due to the complexity of the relatively new legislation, new and
changing regulations, and the impact of political and economic pressures. The
assessment, remediation, analysis, handling and management of hazardous
substances necessarily involve significant risks, including the possibility of
damages or injuries caused by the escape of hazardous materials into the
environment, and the possibility of fines, penalties or other regulatory action.

         The Comprehensive Environmental Response, Compensation and Liability
Act of 1980 ("CERCLA") addresses cleanup of sites at which there has been a
release or threatened release of hazardous substances or contaminants, including
certain radioactive substances, into the environment. CERCLA assigns liability
for costs of cleanup of such sites and for damage to natural resources to any
person who, currently or at the time of disposal of a hazardous substance, owned
or operated any facility at which hazardous substances were disposed of; and to
any person who by agreement or otherwise arranged for disposal or treatment, or
arranged with a transporter for transport for disposal or treatment of hazardous
substances owned or possessed by such person for disposal or treatment by
others; and to any person who accepted hazardous substances for transport to
disposal or treatment facilities or sites selected by such persons from which
there is a release or threatened release of hazardous substances. CERCLA
authorizes the federal government both to clean up these sites itself and to
order persons responsible for the situation to do so. In addition, under the
authority of Superfund and its implementing regulations, detailed requirements
apply to the manner and degree of remediation of facilities and sites where
hazardous substances have been or are threatened to be released into the
environment. CERCLA created the Superfund to be used by the federal government
to pay for the cleanup efforts. Where the federal government expends money for
remedial activities, it may seek reimbursement from the "potentially responsible
parties." CERCLA imposes strict, joint and several retroactive liability upon
such parties. Increasingly, there are efforts to expand the reach of CERCLA to
make environmental contractors responsible for cleanup costs by claiming that
environmental contractors are owners or operators of hazardous waste facilities
or that they arranged for treatment, transportation or disposal of hazardous
substances. Several recent court decisions have accepted these claims. Should
the Company be held responsible under CERCLA for damages caused while performing
services or otherwise, it may be forced to bear such liability by itself,
notwithstanding the potential availability of contribution or indemnity from
other parties.

         The statutory funding mechanism of CERCLA is comprised of contributions
from the general revenue and tax on petrochemical feedstocks. The CERCLA tax
expired December 31, 1995. However, an additional $1.4 billion was appropriated
for fiscal year 1997 and the authority to tax and use the funds has been
extended through September 30, 1997. Additionally, EPA has a large amount of
appropriated, unobligated funds which are projected by the Congressional Budget
Office to be sufficient for EPA to continue operating at current levels for
approximately two years, should there be a lapse in the CERCLA tax after
September 30, 1997.

         The leadership of both the House of Representatives and the Senate have
stressed that reauthorization of Superfund is one of their top priorities for
1997. A bill to reauthorize Superfund has been introduced to the Senate and the
introduction of a House bill is pending. The Senate bill would maintain historic
levels of funding for a period of five years beginning in fiscal year 1998.
Support for environmental programs also remains strong in the Executive Branch.
President Clinton's fiscal year 1998 budget included increases in funding for
all EPA, Department of Defense and Department of Energy environmental programs.

         Despite the priority given to reauthorization of Superfund, and the
history of Congress never to allow an actual lapse in the tax, the perceived
potential for this occurrence adversely impacts the environmental industry due
to resultant funding uncertainties. Additional uncertainties arise from
significant changes being considered for Superfund including shifting the
current preference for permanent treatment to a wider acceptance of containment
and other engineering/institutional controls. This change could lead to smaller
volumes of waste being treated on-site, and the potential to qualify for less
stringent remedies could cause clients to delay the initiation of remediation
projects. However, many of the proposed changes to Superfund are beneficial to
the environmental remediation industry including doubling the dollar amount and
time period in which emergency removal actions take place; increasing contractor
indemnification protections; streamlining the study phase of the process to
accelerate actual remediation; and creating incentives for brownfield cleanups.

         The Resource Conservation and Recovery Act of 1976, as amended in 1984
("RCRA"), is the principal federal statute governing hazardous waste generation,
treatment, storage and disposal. RCRA, or EPA-approved state programs at least
as stringent, govern waste handling activities involving wastes classified as
"hazardous." Under RCRA, liability and stringent operating requirements are
imposed on a person who is either a "generator" or "transporter" of hazardous
wastes, or an "owner"

                                        7


<PAGE>   10



or "operator" of a hazardous waste treatment, storage or disposal facility. The
EPA has issued regulations under RCRA for hazardous waste generators,
transporters and owners and operators of hazardous waste treatment, storage or
disposal facilities. These regulations impose detailed operating, inspection,
training, emergency preparedness and response standards, and requirements for
closure, continuing financial responsibility, manifesting, recordkeeping and
reporting. The Company's clients remain responsible by law for the generation or
transportation of hazardous wastes or ownership or operation of hazardous waste
treatment, storage or disposal facilities. Although the Company does not believe
its conduct in performing environmental remediation services would cause it to
be considered liable as an owner or operator of a hazardous waste treatment,
storage or disposal facility, or a generator or transporter of hazardous wastes
under RCRA, RCRA and similar state statutes regulate the Company's practices for
the treatment, transportation and other handling of hazardous materials, and
substantial fines and penalties may be imposed for any violation of such
statutes and the regulations thereunder.

         The Company's services are also utilized by its clients in complying
with, and the Company's operations are subject to regulation under, among
others, the following federal laws: the Toxic Substances Control Act, the Clean
Water Act, the Safe Drinking Water Act, the Occupational Safety and Health Act
and the Hazardous Materials Transportation Act. In addition, many states have
passed Superfund-type legislation and other statutes, regulations and policies
to cover more detailed aspects of hazardous materials management.

         The Company, through its on-site treatment capabilities and the use of
subcontractors, attempts to minimize its transportation of hazardous substances
and wastes. However, there are occasions, especially in connection with its
emergency response activities, when the Company does transport hazardous
substances and wastes. Such transportation activities are closely regulated by
the United States Department of Transportation, the Interstate Commerce
Commission, and transportation regulatory bodies in each state. The applicable
regulations include licensing requirements, truck safety requirements, weight
limitations and, in some areas, rate limitations and operating conditions.

BACKLOG AND POTENTIAL VALUE OF TERM CONTRACTS

         The following table lists at the dates indicated (i) the Company's
backlog, defined as the unearned portion of the Company's existing contracts and
unfilled orders, and (ii) the Company's term contracts, defined as the potential
value of government term contracts (in thousands):

</TABLE>

         Backlog. In accordance with industry practice, substantially all of the
Company's contracts in backlog may be terminated at the convenience of the
client. In addition, the amount of the Company's backlog is subject to changes
in the scope of services to be provided under any given contract. The Company
estimates that approximately 80% of the backlog at December 31, 1996 will be
realized within the next year.

         Term Contracts. Term contracts typically are performed by completing
remediation work under delivery orders, issued by the contracting government
entity, for a large number of small-to-medium-sized projects throughout the
geographic area covered by the contract. The Company's government term contracts
generally may be canceled, delayed or modified at the sole option of the
government, and typically are subject to annual funding limitations and public
sector budget constraints. Accordingly, such government contracts represent the
potential dollar value that may be expended under such contracts, but there is
no assurance that such amounts, if any, will be actually spent on any projects,
or of the timing thereof.

EQUITY INVESTMENT

         NSC is a provider of asbestos-abatement and other specialty contracting
services to a broad range of commercial, industrial and institutional clients
located throughout the United States. NSC provides asbestos-abatement services
through two of its wholly-owned subsidiaries, National Surface Cleaning, Inc.
and National Service Cleaning Corp.; demolition and dismantling services through
its wholly-owned subsidiary, Olshan Demolishing Management, Inc. ("ODMI"); and
specialty coatings application and lead paint-abatement through its wholly-owned
subsidiary, NSC Specialty Coatings, Inc. In May 1993, the Company's investment
in NSC was reduced from 70% to 40% as a result of NSC's purchase of the asbestos
abatement division of The Brand Companies, Inc. ("Brand") in exchange for its
industrial cleaning and maintenance business and the issuance of

                                        8


<PAGE>   11



4,010,000 shares of NSC common stock. The Company accounts for NSC on the equity
method. In April 1995, NSC entered into an agreement with Rust under which NSC,
through ODMI, assumed the management of Olshan Demolishing Company, a Rust
subsidiary specializing in demolition and dismantling, primarily in the
industrial market. Rust owns another 40% of NSC and the remaining 20% is
publicly held.

         An asbestos-abatement or demolition and dismantling program is focused
on meeting the needs of the facility owner or operator to properly manage the
financial, regulatory and safety-related risks associated with a demolition or
asbestos project. NSC's removal and demolition services require the coordination
of several processes: marketing, bidding and contracting, project management,
health and safety programs, and the actual asbestos removal or dismantling and
demolition. NSC management maintains administrative and operational control over
all phases of a project, from estimating and bidding through project completion.

         Although some of NSC's contracts are directly entered into with its
clients without a formal bidding process, NSC receives a significant portion of
its contracts through a bidding process. The majority of NSC's projects are
contracted on a fixed-price basis, while the remainder are contracted either on
a time and materials or a unit-price basis. All work is done in accordance with
applicable EPA and OSHA regulations and applicable state and local regulations.
NSC is also subject to the regulations of the Mine Safety and Health Act when it
conducts demolition and dismantling projects at mine locations.

         The market for asbestos abatement services is highly competitive. NSC
competes with large asbestos abatement firms, several of which provide services
on a regional basis. NSC also competes, to a lesser extent, with smaller local
and regional firms. While the demand for asbestos-abatement services has
stabilized, demand is still dependent on the fluctuation of national and
regional economies and the finite amount of asbestos remaining to be removed,
there can be no assurance that such demand will remain steady. Through the
diversification into the demolition, specialty coatings and lead paint-abatement
markets, NSC is seeking to provide a full range of specialty contracting
services to the performance-sensitive customer.

         NSC's Board of Directors declared and NSC paid a cash dividend of
$602,000 to the Company for each of the years ended December 31, 1996 and 1995.
While NSC's Board of Directors has not established a policy concerning payment
of regular dividends, it has stated its intention to review annually the
feasibility of declaring additional dividends depending upon the results of
NSC's operations and the financial condition and cash needs of NSC.

ITEM 2. PROPERTIES

         The Company currently owns property in four states and leases property
in 18 states and the District of Columbia. The property owned by the Company
includes approximately 26 acres in Findlay, Ohio, upon which are located the
Company's 37,500 square foot corporate headquarters, a 39,600 square foot
laboratory and technical facility, a 20,000 square foot support services
facility, as well as its fabrication, maintenance and remediation service center
and training facilities. The Company also owns remediation service centers in
Covington, Georgia (approximately ten acres of land and an 8,200 square foot
building), Clermont, Florida (approximately five acres of land and a 6,500
square foot building) and Baton Rouge, Louisiana (approximately ten acres of
land and a 52,500 square foot building).

         The Company operates other offices and remediation service centers in
the following states: California, Colorado, the District of Columbia, Florida,
Georgia, Hawaii, Illinois, Iowa, Massachusetts, Minnesota, Missouri, New Jersey,
New York, Ohio, Pennsylvania, Tennessee, Texas, Virginia and Washington. All of
these offices and service center facilities are leased. Under these leases, the
Company is required to pay base rentals, real estate taxes, utilities and other
operating expenses. Annual rental payments for the remediation service centers
and office properties are approximately $4,500,000.

ITEM 3. LEGAL PROCEEDINGS

         The Company is currently in litigation in the U.S. District Court for
the Western District of Louisiana with Citgo Petroleum Corporation ("Citgo"),
Oxy USA Inc., and Occidental Oil & Gas (collectively "Oxy") relating to cost
overruns and production shortfalls on a remediation project which was performed
by the Company for Citgo at its Lake Charles, Louisiana refinery during 1993 and
1994. The Company has recorded in its financial statements approximately
$27,609,000 as a claim receivable and $5,381,000 of accounts receivable that are
in dispute for work performed under the terms of the Company's base contract
with Citgo. The Company is seeking damages in excess of $35,000,000. Citgo's
second amended complaint seeks damages under the contract for production
shortfalls, which Citgo has asserted in answer to the Company's interrogatories
to be approximately $27,600,000. The Company has filed a third party complaint
against Oxy for negligent misrepresentation and

                                        9


<PAGE>   12



detrimental reliance as a result of Oxy's involvement with the development of
sample and analytical data relied upon by the Company in preparation of its bid
and cost estimates for work at the Lake Charles refinery. In December 1996 and
January 1997, Oxy and Citgo, respectively, filed motions for summary judgment
and partial summary judgment on the Company's claims. The Company filed briefs
in opposition to these motions. These motions for summary judgment and partial
summary judgment are still pending.

         The Company is currently in litigation in the U.S. District Court for
the Western District of New York with Occidental Chemical Corporation
("Occidental") relating to the Durez Inlet Project performed in 1993 and 1994
for Occidental in North Tonawanda, New York. The Company's accounts receivable
at December 31, 1996 include a claim receivable of $8,618,000 related to this
matter. The Company's work was substantially delayed and its costs of
performance were substantially increased as a result of conditions at the site
which the Company believes were materially different than as represented by
Occidental. Occidental's amended complaint seeks $8,806,000 in damages primarily
for alleged costs incurred as a result of project delays and added volumes of
incinerated waste. The Company's counterclaim seeks an amount in excess of
$9,200,000 for damages arising from Occidental's breach of contract,
misrepresentation and failure to pay outstanding contract amounts.

         The Company is currently in arbitration proceedings with Separation and
Recovery Systems, Inc. ("SRS") resulting from SRS's failure to adequately
perform it's subcontract obligations to the Company for thermal desorption
services at the Hilton- Davis project in Cincinnati, Ohio. The Company's
financial statements on December 31, 1996 include a back charge receivable of
approximately $7,345,000 representing additional costs the Company has and will
incur as a result of completing SRS's scope of work under its thermal desorption
subcontract with the Company. SRS has filed a counterclaim against the Company
for approximately $2,500,000 alleging wrongful termination of the subcontract.

         Management believes that it has established adequate reserves should
the resolution of the above matters be lower than the amounts recorded. There
is, however, always risk and uncertainty in pursuing and defending litigation
and arbitration proceedings in the course of the Company's business and,
notwithstanding the reserves currently established, adverse future results in
litigation or other proceedings could have a material adverse impact upon the
Company's consolidated future results of operations or financial condition.

         In addition to the above, the Company is subject to a number of claims
and lawsuits in the ordinary course of its business. In the opinion of
management, the outcome of these actions, which are not clearly determinable at
the present time, are either adequately covered by insurance, or if not insured,
will not, in the aggregate, have a material adverse impact upon the Company's
consolidated financial position or the results of future operations.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

(a)      RESULTS OF OPERATIONS

                                     GENERAL

         The Company provides a broad range of environmental and hazardous waste
remediation services to its clients located primarily in the United States. The
timing of the Company's revenue is dependent on its backlog, contract awards and
the performance requirements of each contract. The Company's revenue is also
affected by the timing of its clients' planned remediation activities which
generally increase during the third and fourth quarters. Because of this change
in demand, the Company's quarterly revenue can fluctuate, and revenue for the
first and second quarters of each year have historically been lower than for the
third and fourth quarters, although there can be no assurance that this will
occur in future years. Accordingly, quarterly or other interim results should
not be considered indicative of results to be expected for any quarter or full
fiscal year.

         On May 30, 1995, the Company completed the acquisition of substantially
all of the assets and certain liabilities of the hazardous and nuclear waste
remediation service business (the "Division") of Rust International Inc.
("Rust") in exchange for 9,668,000 shares of Common Stock of the Company, or
approximately 37% of the outstanding shares of the Company's Common Stock. In
exchange for a warrant to purchase up to 700,000 shares of the Company's common
stock at an exercise price of $15.00 per share during the five years following
the closing date, Rust's parent Company, WMX Technologies, Inc. ("WMX"),
provided the Company with a credit enhancement in the form of guarantees, issued
from time to time upon request of the Company, of up to $62,000,000 of the
Company's indebtedness, which will increase proportionately up to $75,000,000
upon issuance of shares under the warrant. The acquisition of the Division has
been accounted for using the purchase method and, accordingly, the acquired
assets and assumed liabilities, including goodwill, have been recorded at their
estimated fair values as of May 30, 1995. See "Note 2 to the Consolidated
Financial Statements." The Company's consolidated financial statements include
the results of operation for the Division since May 30, 1995.

         During the second quarter of 1995, the Company recorded a $3,854,000
pre-tax, $2,312,000 after-tax or $0.10 per share, charge for integration costs
related to the acquisition of the Division. The charge was recorded as a
selling, general and administrative expense and was primarily for severance and
relocation costs for certain of the Company's personnel and the closing of
certain of the Company's offices as a result of combining the operations of the
Division and the Company.

         During the fourth quarter of 1994, certain developments within and
external to the Company caused management to revaluate certain accounts
receivable recorded during 1994. As a result, the Company recorded a $25,000,000
pre-tax charge against revenue, $15,000,000 after-tax or $0.96 per share, to
establish a reserve for accounts receivable, primarily where such accounts are
in litigation, including projects performed by the Company for Citgo Petroleum
Company ("Citgo") and Occidental Chemical Corporation ("Occidental"). See "Note
15 to the Consolidated Financial Statements."

         The following table sets forth, for the periods indicated, the
percentage relationship that items in the statement of operations bear to
revenue:

</TABLE>

         Total revenue for the year ended December 31, 1996, increased 20% to
$550,984,000 from $457,925,000 in 1995. Such improvement resulted primarily from
increased revenue from federal government agencies. In addition, revenue from
industrial sector clients was favorably impacted by the acquisition of the
Division, which was included for a full year in 1996 compared to only seven
months of 1995.

         Revenue from government agencies for the twelve months ended December
31, 1996 increased $77,204,000 or 22% from $349,052,000 in 1995. This
improvement resulted primarily from an increase in revenue from the Company's
term contracts with the United States Air Force ("Air Force"), the United States
Army Corps of Engineers ("USACE"), the Department of Energy ("DOE") and the
United States Navy ("Navy"). Such increases were partially offset by a decrease
in revenue from state and local governments and the Environmental Protection
Agency ("EPA") during 1996. The federal government shutdown during the first
quarter of 1996 negatively impacted the Company's revenue from the EPA and
delayed delivery orders issued under the Company's existing federal term
contracts. The Company expects to continue to receive funding under its federal
contracts into the foreseeable future and continues to experience a significant
amount of proposal activity for new contracts with the various Department of
Defense ("DOD") agencies, as well as the DOE. However, no assurance can be given
that the Company will be awarded any new contracts with the DOD or DOE. In
addition, reductions by Congress in future environmental remediation budgets of
government agencies may have a material adverse impact upon future revenue from
such agencies and the funding of the Company's government term contracts
included in contract backlog.

         The Company experienced a $15,855,000 or 15% increase in revenue from
industrial clients for the year ended December 31, 1996 as compared to 1995.
Such increase is primarily a result of the acquisition of the Division during
May 1995. The Company believes that revenue growth from the industrial sector
has been negatively impacted due to anticipated changes in the Superfund law
pending its reauthorization as well as current economic conditions in certain
industry and geographic sectors. Although the Company cannot predict the impact
upon the environmental industry of the failure of Congress to reauthorize the
Superfund law, further delays in Superfund reauthorization may have a material
impact upon the demand for the Company's services in the form of project delays
as clients and potential clients wait for and anticipate changes in these
regulations. In addition, demand for the Company's services from the industrial
sector will also remain dependant on general economic conditions.

         During 1996, the Company's government revenue as a percent of total
revenue was 77%. The Company believes that the government sector will continue
to be its primary source of revenue for the foreseeable future in light of the
factors discussed above.

         Cost of Services and Gross Profit. Cost of services for the year ended
December 31, 1996 increased 22% to $478,924,000 from $393,149,000 in 1995
primarily due to increased revenue. Cost of services as a percentage of revenue
increased to 87% for the year ended December 31, 1996 from 86% for 1995.

         Gross profit increased 11% to $72,060,000 in 1996 from $64,776,000 in
1995. The increase in gross profit is primarily due to increased revenues. Gross
profit as a percentage of revenue decreased to 13% for the year ended December
31, 1996 from 14% in 1995. The Company's gross profit on its fixed-price
contracts has been negatively impacted by competitive market conditions and,
during the first quarter of 1996, by the severe winter weather in the midwest
and northeast regions of the country. In addition, the Company has experienced a
decrease in the overall gross margin it has received on its government projects
as a result of the nature of the projects that have been awarded to the Company
under its term contracts which has required an increase in the use of
subcontracted services and materials over levels historically experienced. Under
the terms of such contracts, the Company receives minimal markups on such
subcontracted services and materials.

                                       16


<PAGE>   19



         The Company believes the trend towards the use of subcontracted
services and materials for government projects will continue. In addition,
competitive pressure for future industrial sector projects will continue due to
the lack of regulatory enforcement, and resultant diminished number of contract
opportunities, as a result of the failure of Congress to reauthorize the
Superfund law. Both of these factors will continue to impact the Company's gross
profit margin on its contracts into the foreseeable future.

         Selling, General and Administrative Expenses. Selling, general and
administrative ("SGA") expenses for the year ended December 31, 1996 increased
9% to $49,250,000 from $45,223,000 in 1995. SGA expenses for the year ended
December 31, 1995 include the aforementioned charge of $3,854,000 for
integration costs related to the acquisition of the Division. Without such
charge, SGA expenses increased 19% primarily as a result of the acquisition of
the Division and the growth in revenue. In addition, the Company has made a
substantial investment in personnel and systems in support of its government
contracts and related compliance issues. SGA expense as a percent of revenue was
9% for the twelve months ended December 31, 1996 and 1995, exclusive of the
integration charge in 1995.

         Interest expense. Interest expense, net of investment income, decreased
27% to $6,963,000 for the year ended December 31, 1996 from $9,564,000 for 1995.
The decrease in interest expense was a result of a decrease in the average
borrowings outstanding, as well as interest rates charged, under the Company's
revolving credit agreement during 1996 compared to 1995. The decrease in
interest rates charged under the revolving credit agreement primarily is a
result of the WMX guarantee of the Company's debt in exchange for the warrant
described above. Investment income for the twelve months ended December 31, 1995
included income earned on certain outstanding receivables guaranteed by Rust
pursuant to the agreement for the acquisition of the Division. Such receivables
were paid to the Company on September 30, 1995.

         Equity in Net Earnings of Affiliate. The Company's equity interest in
NSC's net earnings increased $461,000 to $748,000 in 1996 from $287,000 in 1995.
The twelve months ended December 31, 1995 was negatively impacted by the
settlement of claims with certain clients of NSC as well as increases in
insurance reserves. NSC has experienced a decrease in revenues from asbestos
abatement contracts for the twelve months ended December 31, 1996 compared to
1995. Such decrease in revenue was more than offset by increases in revenue from
its specialty contractor services subsidiary, Olshan Demolishing Management,
Inc. The asbestos abatement industry in general continues to experience
competitive pressures in the marketplace which have negatively impacted the
gross margin on NSC's projects.

         Net Income. Net income for the year ended December 31, 1996 was
$11,515,000 or $0.43 per share compared to $6,807,000 or $0.30 per share in
1995. The improvement in net income is primarily due to increased revenue, the
integration charge recorded during 1995, decreased interest expense and other
factors discussed above.

</TABLE>

         Total revenue for the year ended December 31, 1995, increased 42% to
$457,925,000 from $323,381,000 in 1994. Such improvement resulted primarily from
increased revenue from federal government agencies and the acquisition of the
Division.

         During 1995, the Company experienced a $140,442,000 or a 67% increase
in revenue from government agencies. This improvement resulted primarily from an
increase in revenue from the Company's term contracts with the Navy, the USACE
and the Air Force, as well as increased revenue from other federal government
agencies. Such increases were partially offset by a decrease in revenue from
state and local governments for the year ended December 31, 1995 when compared
to 1994.

         The Company experienced a $5,898,000 or 5% decrease in revenue from
industrial clients for the year ended December 31, 1995 as compared to 1994.
Such revenue would have decreased further if not for the Company's acquisition
of the Division during May 1995. The Company believes that revenue from the
industrial sector has been negatively impacted due to anticipated changes in the
Superfund law pending its reauthorization as well as economic conditions in
certain industry and geographic

                                       17

sectors. Industrial sector revenue was negatively impacted for the year ended
December 31, 1994 by the previously discussed $25,000,000 accounts receivable
reserve which was primarily related to industrial clients. Industrial sector
revenue as a percentage of total revenue decreased to 24% for 1995 from 35% in
1994.

         Cost of Services and Gross Profit. Cost of services for the year ended
December 31, 1995 increased 33% to $393,149,000 from $296,159,000 in 1994
primarily due to increased revenue. Cost of services as a percentage of revenue
decreased to 86% for the year ended December 31, 1995 from 92% for 1994. Such
decrease is primarily due to the aforementioned charge for accounts receivable
recorded during the fourth quarter of 1994. Cost of services as a percentage of
revenue for 1994 would have been 85% without the accounts receivable charge.

         Gross profit increased 138% to $64,776,000 in 1995 from $27,222,000 in
1994. The increase in gross profit is primarily due to the increase in revenue
and the accounts receivable charge recorded in 1994. The Company has experienced
a slight decrease in the overall gross margin it has received on its government
projects than it has historically experienced. Such decrease is due to the
nature of the projects that have been awarded to the Company under its term
contracts which has required an increase in the use of subcontracted services
and materials over levels historically experienced. Under the terms of such
contracts, the Company receives minimal markups on such subcontracted services
and materials.

         In addition, cost of services and gross profit have been negatively
impacted by the acquisition of the Division during 1995. The Company has
incurred additional indirect cost of services for the Division's offices and
employees, while revenue from the Division's projects were significantly lower
than expected during 1995.

         Selling, General and Administrative Expenses. SGA expenses for the year
ended December 31, 1995 increased 40% to $45,223,000 from $32,281,000 in 1994.
SGA expenses for the year ended December 31, 1995 include the previously
discussed charge of $3,854,000 for integration costs related to the acquisition
of the Division. Without such charge, SGA expenses increased 28% primarily as a
result of the acquisition of the Division and the growth in revenue.

         Interest expense. Interest expense, net of investment income, increased
5% to $9,564,000 for the year ended December 31, 1995 from $9,149,000 for 1994.
The increase in interest expense was offset by interest earned on certain
outstanding receivables guaranteed by Rust pursuant to the agreement for the
acquisition of the Division. Such receivables guaranteed by Rust were paid to
the Company on September 30, 1995. The increase in interest expense was
primarily due to additional borrowing under the Company's credit facility during
the first half of 1995 as a result of the increased working capital requirements
of certain large remediation projects and government contracts.

         Equity in Net Earnings of Affiliate. The Company's equity interest in
NSC's net earnings decreased $745,000 to $287,000 in 1995 from $1,032,000 in
1994. Such decrease in earnings is primarily a result of losses recorded by NSC
on claims settled in the third quarter of 1995 with certain of its clients and
an increase in insurance reserves. The asbestos abatement industry in general
continues to experience competitive pressures in the marketplace which have
negatively impacted the gross margin on NSC's projects.

         Net Income (Loss). Net income for the year ended December 31, 1995 was
$6,807,000 or $0.30 per share compared to a net loss of $(7,616,000) or $(0.49)
per share in 1994. The improvement in net income is primarily due to the reserve
recorded for accounts receivable during 1994 and other factors discussed above.

         Backlog. In accordance with industry practice, substantially all of the
Company's contracts in backlog may be terminated at the convenience of the
client. In addition, the amount of the Company's backlog is subject to changes
in the scope of services to be provided under any given contract. The Company
estimates that approximately 80% of the backlog at December 31, 1996 will be
realized within the next year.

         Term Contracts. Term contracts are typically performed under delivery
orders, issued by the contracting government entity, for a large number of
small-to medium-sized remediation projects throughout the geographic area
covered by the contract. The Company's government term contracts generally may
be canceled, delayed or modified at the sole option of the government, and
typically are subject to annual funding limitations and public sector budget
constraints. Accordingly, such government contracts represent the potential
dollar value that may be expended under such contracts, but there is no
assurance that such amounts, if any, will be actually spent on any projects or
of the timing thereof. In addition, further reductions by Congress in future
environmental remediation budgets of government agencies may adversely impact
future revenue from such agencies and the funding of the Company's government
term contracts included in contract backlog.

(b)      LIQUIDITY AND CAPITAL RESOURCES

         On May 31, 1995, the Company entered into a $150,000,000 revolving
credit agreement with a group of banks (the "Bank Group") to provide letters of
credit and cash borrowings. The agreement has a five year term and is scheduled
to expire on May 30, 2000. WMX has issued a guarantee of up to $62,000,000
outstanding under the credit agreement in favor of the Bank Group. See "Note 2
to the Consolidated Financial Statements." Under the terms of the agreement the
entire credit facility can be used for either cash borrowings or letters of
credit. Cash borrowings bear interest at either the prime rate plus a percentage
up to 0.625% or, at the Company's option, the Eurodollar market rate plus a
percentage ranging from 0.325% to 1.625%. The percentage over the prime rate or
the Eurodollar market rate is based on the aggregate amount borrowed under the
facility, the presence of the guarantee, and the Company's financial performance
as measured by an interest coverage ratio and a total funded debt ratio. The
agreement provides the participating banks with a security interest in the
Company's equipment, inventories, accounts receivables, general intangibles and
in the Company's investment in the common stock of NSC as well as the Company's
other subsidiaries. The agreement also imposes, among other covenants, a minimum
tangible net worth covenant, a restriction on all of the Company's retained
earnings including the declaration and payment of cash dividends and a
restriction on the ratio of total funded debt to earnings before income taxes,
depreciation and amortization. The amounts outstanding for cash borrowing under
the revolving credit facility at December 31, 1996 and 1995 were $0 and
$42,100,000, respectively, and aggregate letters of credit outstanding at
December 31, 1996 and 1995 were $12,223,000 and $14,655,000, respectively.

         Capital expenditures for the years ended December 31, 1996, 1995, and
1994 were $23,279,000, $14,276,000, and $13,354,000, respectively. The Company's
capital expenditures are primarily related to the installation of computer
systems and related equipment, the purchase of heavy construction equipment and
the fabrication of custom equipment by the Company for the execution of
remediation projects. Capital expenditures for fiscal year 1997 are expected to
range between $20,000,000 and $25,000,000. The Company's long-term capital
expenditure requirements are dependent upon the type and size of future
remediation projects awarded to the Company.

         During 1996, the Company derived 77% of its revenue from government
agencies. Revenue from government agencies historically has required greater
working capital, the major component of which is accounts receivable, than
revenue from industrial sector clients. In addition, the Company is bidding on a
number of large, long-term contract opportunities with industrial sector
clients, the DOD and the DOE which, if awarded to the Company, would also
increase working capital needs and capital expenditures. The Company believes it
will be able to finance its increased working capital needs and capital
expenditures in the short term through a combination of cash flows from
operations, borrowings under its Revolving Credit Facility, proceeds from
permitted asset sales, utilization of operating leases and other external
sources. In addition, under the terms of the acquisition of Rust's hazardous and
nuclear waste remediation business, Rust's parent Company, WMX, has provided the
Company with a credit guarantee of up to $62,000,000 of the Company's
indebtedness outstanding until May 30, 2000. See "Note 2 to the Consolidated
Financial Statements." Such credit guarantee has allowed the Company to expand
its borrowing capacity and lower its cost of capital under its new credit
facility entered into on May 31, 1995.

         The Company, from time to time, evaluates potential acquisitions of
companies in the environmental remediation industry and industries related to
the core skills of the Company. While the Company believes that there are
currently available a number of potential acquisition candidates that would be
complementary to its business, the Company currently has no agreements,
understandings or arrangements to acquire a specific business or other material
assets. The Company cannot predict whether it will be successful in pursuing
such acquisition opportunities or what the consequences of any such acquisition
would be. Future

                                       19


<PAGE>   22



acquisitions may involve the expenditure of significant funds and management
time. Depending upon the nature, size and timing of future acquisitions, the
Company may be required to raise additional capital through financings,
including public or private equity or debt offerings or additional bank
financing. There is no assurance that such additional financing will be
available to the Company on acceptable terms.

         The Company's identified long-term capital needs consist of payments
due upon the maturity of the Company's Revolving Credit Facility in 2000 and
sinking fund payments which commenced in 1996 of 7.5% of the principal amount as
well as payments due upon maturity of its Convertible Debentures in 2006. The
Company has purchased and retired $10,736,000 of the outstanding Convertible
Debentures during 1995 and 1996, sufficient to meet its annual sinking fund
obligations through October 1, 1997, as well as a portion of the sinking fund
obligation due October 1, 1998. The Company believes that it will be able to
refinance the remaining indebtedness as necessary. See "Note 7 to the
Consolidated Financial Statements."

(c)      INFLATION

         Historically, inflation has not been a significant factor to the
Company or to the cost of its operations.

(d)      DEFERRED TAX ASSETS

         The Company has recorded a valuation allowance for its deferred tax
assets to the extent that the Company believes such deferred tax assets may not
be realized. With respect to deferred tax assets for which a valuation allowance
has not been established, the Company believes it will realize the benefit of
these assets through the reversal of taxable temporary differences and future
income. The Company believes that the future taxable income of approximately
$36,092,000 necessary to realize the deferred tax assets is more likely than not
to occur because of its substantial backlog and term contracts from which the
Company has historically realized sufficient margin to produce consolidated net
income. The principal uncertainty of realization of the deferred tax assets is
the Company's ability to convert its backlog to revenue and margin. See
"Contract Backlog" and "Environmental Matters and Government Contracting" in
other sections of Management's Discussion and Analysis of Financial Condition
and Results of Operations. The Company intends to evaluate the realizability of
its deferred tax assets quarterly by assessing the need for an additional
valuation allowance. See "Note 9 to the Consolidated Financial Statements."

(e)      ENVIRONMENTAL MATTERS AND GOVERNMENT CONTRACTING

         Although the Company believes that it generally benefits from increased
environmental regulations and from enforcement of those regulations, increased
regulation and enforcement also create significant risks for the Company. The
assessment, remediation, analysis, handling and management of hazardous
substances necessarily involve significant risks, including the possibility of
damages or injuries caused by the escape of hazardous materials into the
environment, and the possibility of fines, penalties or other regulatory action.
These risks include potentially large civil and criminal liabilities for
violations of environmental laws and regulations, and liabilities to customers
and to third parties for damages arising from performing services for clients,
which could have a material adverse effect on the Company.

         The Company does not believe there are currently any material
environmental liabilities which should be recorded or disclosed in its financial
statements. The Company anticipates that its compliance with various laws and
regulations relating to the protection of the environment will not have a
material effect on its capital expenditures, future earnings or competitive
position.

         Because of its dependence on government contracts, the Company also
faces the risks associated with such contracting, which could include civil and
criminal fines and penalties. As a result of its government contracting
business, the Company has been, is, and may in the future be subject to audits
and investigations by government agencies. The fines and penalties which could
result from noncompliance with the Company's government contracts or appropriate
standards and regulations, or the Company's suspension or debarment from future
government contracting, could have a material adverse effect on the Company's
business.

                                 OHM CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                DECEMBER 31, 1996

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION. The accompanying
consolidated financial statements include the accounts of OHM Corporation (the
"Company") and its subsidiaries. The Company also includes its proportionate
share of joint ventures, in which the Company's ownership is less than 50%,
which were entered into for the purpose of performing large remediation
projects. The Company's investment in 40% of the outstanding common stock of NSC
Corporation ("NSC") is carried on the equity basis. All material intercompany
transactions and balances among the consolidated group have been eliminated in
consolidation.

         USE OF ESTIMATES. The preparation of the accompanying consolidated
financial statements in conformity with generally accepted accounting principles
requires management to make estimates and assumptions that affect the amounts
reported in the consolidated financial statements and the accompanying notes.
Actual results could differ from those estimates.

         RISKS AND UNCERTAINTIES. The Company provides a broad range of
environmental and hazardous waste remediation services to its clients located
primarily in the United States. The assessment, remediation, analysis, handling
and management of hazardous substances necessarily involve significant risks,
including the possibility of damages or injuries caused by the escape of
hazardous material into the environment, and the possibility of fines, penalties
or other regulatory action. These risks include potentially large civil and
criminal liabilities for violations or environmental laws and regulations, and
liability to customers and to third parties for damages arising from performing
services for clients, which could have a material adverse effect on the Company.
Although the Company believes that it generally benefits from increased
environmental regulations, and from enforcement of those regulations, increased
regulation and enforcement also create significant risks for the Company.

         The Company does not believe there are currently any material
environmental liabilities which should be recorded or disclosed in its financial
statements. The Company anticipates that its compliance with various laws and
regulations relating to the protection of the environment will not have a
material effect on its capital expenditures, future earnings or competitive
position.

         The Company's revenue from government agencies accounted for 77%, 76%
and 65% of revenue for the years ended December 31, 1996, 1995 and 1994,
respectively. Because of its dependence on government contracts, the Company
also faces the risks associated with such contracting, which could include civil
and criminal fines and penalties. As a result of its government contracting
business, the Company has been, is and may in the future be subject to audits
and investigations by government agencies. The fines and penalties which could
result from noncompliance with the Company's government contracts or appropriate
standards and regulations, or the Company's suspension or debarment from future
government contracting, could have a material adverse effect on the Company's
business. The dependence on government contracts will also continue to subject
the Company to significant financial risk and an uncertain business environment
caused by the strain of the federal budget deficit and the lengthy budget
negotiations each year.

         In addition to the above, there are other risks and uncertainties that
involve the use of estimates in the preparation of the Company's consolidated
financial statements. See "Note 2 - Acquisition" and "Note 15 - Litigation and
Contingencies."

         STOCK-BASED COMPENSATION. The Company grants stock options for a fixed
number of shares to employees and members of the Board of Directors with an
exercise price equal to the fair value of the shares at the date of grant. The
Company accounts for stock compensation arrangements in accordance with APB
Opinion No. 25, "Accounting for Stock Issued to Employees," ("APB No. 25") and
accordingly, recognizes no compensation expense for the stock compensation
arrangements. The Company has no intention of changing this accounting practice.
The pro forma information regarding net income and earnings per share as
required by Statement of Financial Accounting Standards No. 123, "Accounting for
Stock-Based Compensation" ("SFAS No. 123") is disclosed in "Note 13 - Stock
Option Plan."

         REVENUE AND COST RECOGNITION. The Company primarily derives its revenue
from providing environmental services under cost plus fee, time and materials,
fixed price and unit price contracts. The Company records revenue and related
income from its fixed and unit price contracts in process using the
percentage-of-completion method of accounting. Provisions for estimated losses
on uncompleted contracts are made in the period in which such losses are
determined. Changes in project performance, project

                                       26

conditions and estimated profitability may result in revisions to costs and
income and are recognized in the period in which the revisions are determined.
An amount equal to contract costs attributable to claims is included in revenue
when realization is probable and the amount can be reliably estimated. Back
charges to subcontractors are recorded as receivables to the extent considered
collectible. Revenue from time and materials and cost plus fee type contracts is
recorded based on performance and efforts expended. Contract costs include all
direct labor, material, per diem, subcontract and other direct and indirect
project costs related to contract performance. Revenue derived from non-contract
activities is recorded when the services are performed.

         PROPERTY AND EQUIPMENT. Property and equipment are carried at cost and
include expenditures which substantially increase the useful lives of the
assets. Maintenance, repairs and minor renewals are expensed as incurred.
Depreciation and amortization, including amortization of assets under capital
leases, are provided on a specific item basis net of salvage value over the
estimated useful lives of the respective assets, using the units of production
method on thermal destruction equipment and the straight-line method on all
other fixed assets.

         CAPITALIZED INTEREST. Interest expense incurred on capital expenditures
for assets constructed by the Company is capitalized and is included in the cost
of such assets. Total interest expense incurred by the Company was $8,085,000,
$11,205,000 and $10,127,000 for the years ended December 31, 1996, 1995 and
1994, respectively. Total interest capitalized was $998,000, $792,000 and
$950,000 for the years ended December 31, 1996, 1995 and 1994, respectively.

         INTANGIBLE ASSETS. Intangible assets consist principally of goodwill
and other intangible assets resulting primarily from acquisitions accounted for
using the purchase method of accounting. Goodwill is amortized using the
straight-line method over forty years. The carrying value of goodwill is
reviewed if the facts and circumstances suggest that it may be impaired. If this
review indicates that goodwill will not be recoverable, as determined based on
the undiscounted cash flows of the entity acquired over the remaining
amortization period, the Company's carrying value of the goodwill will be
reduced by the estimated shortfall of cash flows. Other intangible assets
relating to acquired businesses consist principally of proprietary processes,
and other deferred costs, and are amortized on a straight-line basis over nine
to ten years. The accumulated amortization of intangible assets, including
goodwill, relating to acquired businesses, was $1,938,000 and $1,159,000 at
December 31, 1996 and 1995, respectively.

         INCOME TAXES. The Company accounts for income taxes under the liability
method pursuant to Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes" ("SFAS No. 109"). Under the liability method,
deferred tax assets and liabilities are determined based on differences between
the financial reporting and tax bases of assets and liabilities using the
enacted tax rates and laws that will be in effect when the differences are
expected to reverse.

         STATEMENT OF CASH FLOWS. The Company considers all short-term deposits
and highly liquid investments purchased with an original maturity of three
months or less to be cash equivalents. Cash paid for income taxes for the years
ended December 31, 1996, 1995 and 1994 was $482,000, $986,000 and $550,000,
respectively. Cash paid for interest was $8,137,000, $10,937,000 and $9,171,000
for each of the years ended December 31, 1996, 1995 and 1994, respectively.

         With respect to non-cash investing and financing activities, the
Company acquired $1,870,000, $29,000 and $91,000 of fixed assets under financial
obligations for the years ended December 31, 1996, 1995 and 1994, respectively.
In addition, the Company issued 9,668,000 shares of its common stock in fiscal
1995 for an acquisition. See "Note 2 - Acquisition."

         NET INCOME (LOSS) PER SHARE. Net income (loss) per share amounts are
based on the weighted average common and common equivalent shares outstanding
during the respective periods. Shares of common stock issuable upon conversion
of the 8% Convertible Subordinated Debentures due 2006 are not considered to be
common stock equivalents and were antidilutive in each of the years presented;
therefore, they were excluded from the calculation of net income per share.

         RECLASSIFICATION. Certain amounts presented for the years ended
December 31, 1995 and 1994 have been reclassified to conform to the 1996
presentation.

NOTE 2 - ACQUISITION

         On May 30, 1995, the Company completed the acquisition of substantially
all of the assets and certain liabilities of the hazardous and nuclear waste
remediation service business (the "Division") of Rust International Inc.
("Rust") in exchange for 9,668,000 shares of common stock of the Company, or
approximately 37% of the outstanding shares of the Company's common stock. Such
shares issued to Rust are subject to a number of restrictions set forth in a
Standstill and Non-competition Agreement that was entered into pursuant to the
Agreement and Plan of Reorganization dated December 5, 1994, as amended (the
"Reorganization Agreement"), among the Company, Rust and certain of their
subsidiaries. In addition to the net assets of the

                                       27


<PAGE>   30
Division, the Company received $16,636,000 in cash pursuant to provisions of the
Reorganization Agreement that provided for an adjustment based on the average
per share price of the Company's common stock for a 20 trading day period prior
to closing. Also, under terms of the Reorganization Agreement, as amended on
March 22, 1996, the Company received an additional $15,000,000 on March 25,
1996. For purposes of calculating the consideration given by the Company for the
Division, such 20 trading day average per share price of $11.25 was used,
adjusted to reflect a 40% discount for the restricted nature of the common stock
issued. Consideration for the Division aggregated $65,259,000, which includes
$3,143,000 of direct costs related to the acquisition.

         In exchange for a warrant to purchase up to 700,000 shares of the
Company's common stock at an exercise price of $15.00 per share during the five
years following the closing date, Rust's parent company, WMX Technologies, Inc.
("WMX"), will provide the Company with a credit enhancement in the form of
guarantees, issued from time to time upon request of the Company, of up to
$62,000,000 of the Company's indebtedness, which will increase proportionately
up to $75,000,000 upon issuance of shares under the warrant.

         The acquisition of the Division has been accounted for using the
purchase method and, accordingly, the acquired assets and assumed liabilities
have been recorded at their estimated fair values as of May 30, 1995. The
acquired operations of the Division included contracts in process for which the
Company recognizes revenue using the percentage of completion method of
accounting. The valuation of the contracts in process require estimates relating
to the costs to complete certain large contracts in process which require
provisions for losses. The Company has estimated the fair value of contracts
acquired at amounts which will allow the Company to achieve reasonable operating
margins on the effort it expends to complete these contracts. The Company
resolved certain preacquisition contingencies pending at December 31, 1995 and
finalized the purchase accounting adjustments during the second quarter of 1996.
As a result of the final purchase accounting adjustments, goodwill was increased
by $12,700,000. The Company's consolidated financial statements include the
results of operations for the Division since May 30, 1995. The following table
sets forth the unaudited combined pro forma results of operations for the year
ended December 31, 1995 and 1994 giving effect to the acquisition of the
Division as if such acquisition had occurred on January 1, 1994.

         Unbilled receivables and costs and estimated earnings on contracts in
process typically represent: (i) amounts earned under the Company's contracts
but not yet billable to clients according to contract terms, which usually
consider passage of time, achievement of certain project milestones or
completion of the project; and (ii) amounts equal to contract costs attributable
to claims included in revenue. In addition, unbilled receivables and costs and
estimated earnings on contracts in process include amounts relating to contracts
with federal government agencies which require services performed by the
Company's subcontractors to be paid prior to billing.

         The Company provides a broad range of environmental and hazardous waste
remediation services to industrial, federal government agencies, and state and
local government agencies located primarily in the United States and Canada. The
Company's industrial, federal government, and state and local government clients
constituted 44%, 52%, and 4%, respectively, of total accounts receivable and
costs and estimated earnings on contracts in process at December 31, 1996.

         The reserve for loss projects is related to certain contracts in
process of the acquired Division. The reduction in such reserve during 1996 was
a result of losses incurred on projects of the Division and a $4,687,000
reclassification recorded as a reduction to goodwill, which resulted from the
final purchase accounting adjustments recorded in the second quarter of 1996.

         The convertible subordinated debentures are convertible into 41.67
shares of common stock per $1,000 unit with interest payable semiannually on
April 1 and October 1, and are redeemable at the option of the Company. The
convertible subordinated debentures require annual mandatory sinking fund
payments of 7.5% of the principal amount which commenced in 1996, and continue
through October 1, 2005. The Company purchased and retired $5,736,000 and
$5,000,000 of the outstanding debentures during 1996 and 1995, respectively,
sufficient to meet the first and second annual sinking fund obligations due
October 1, 1996 and 1997 which resulted in a gain of $492,000 and $222,000 and
have been included in miscellaneous income in the Company's statement of
operations for the years ended December 31, 1996 and 1995, respectively. The
fair value of the convertible subordinated debentures, based on a quoted market
price, approximates $43,491,000 at December 31, 1996. The amortization of debt
issuance costs related to the convertible subordinated debentures was $97,000,
$108,000 and $108,000 for the years ended December 31, 1996, 1995 and 1994,
respectively.

         On May 31, 1995, the Company entered into a $150,000,000 revolving
credit agreement with a group of banks (the"Bank Group") to provide letters of
credit and cash borrowings. The agreement has a five year term and is scheduled
to expire on May 30, 2000. WMX has issued a guarantee of up to $62,000,000
outstanding under the credit agreement in favor of the Bank Group. See "Note 2 -
Acquisition." Under the terms of the agreement the entire credit facility can be
used for either cash borrowings or letters of credit subject to certain
covenants. Cash borrowings bear interest at either the prime rate plus a
percentage up to 0.625% or, at the Company's option, the Eurodollar market rate
plus a percentage ranging from 0.325% to 1.625%. The percentage over the prime
rate or the Eurodollar market is based on the aggregate amount borrowed under
the facility, the presence of the WMX guarantee, and the Company's financial
performance as measured by an interest coverage ratio and a total funded debt
ratio. The arrangement provides the participating banks and WMX with a security
interest in the Company's equipment, inventories, accounts receivables, general
intangibles and in the Company's investment in the common stock of NSC as well
as the Company's other subsidiaries. The agreement also imposes, among other
covenants, a minimum tangible net worth covenant, a restriction on all of the
Company's retained earnings including the declaration and payment of cash
dividends and a restriction on the ratio of total funded debt to earnings before
income taxes, depreciation and amortization. The Company had $12,223,000 and
$14,655,000 of letters of credit outstanding under its revolving credit facility
at December 31, 1996 and 1995, respectively.

         Notes payable to financial institutions consist of: (i) a $3,246,000
note payable bearing interest at 7.24% payable in equal monthly installments of
$146,000 with the final payment due in December 1998, (ii) a $772,000 note
payable bearing interest at 9.25% payable in equal monthly installments of
$35,000 with the final payment due in December 1998, (iii) a $3,927,000 note
payable bearing interest at 8.58% payable in quarterly installments of $356,000
with the final payment of $957,000 due in August 1999, and (iv) a $489,000 note
payable bearing interest at 8.72% payable in equal monthly installments of
$43,000 with the final payment due in January 1998. Each of the above agreements
provides the respective financial institution with a security interest in the
equipment financed with the proceeds from such notes.

         Notes payable include: (i) a $767,000 interest bearing note at a rate
of 9.50% payable in equal monthly installments of $48,000, due in April 1998,
(ii) a $235,000 interest bearing note at a rate of 9.22% payable in equal
monthly installments of $13,000, due in June 1998, (iii), a $203,000 interest
bearing note at a rate of 7.50% payable in equal monthly installments of $8,000,
due in December 1998, (iv) a $1,503,000 interest bearing note at a rate of 8.67%
payable in equal monthly installments of $48,000, due in July 1999, (v) a

installments of $5,000, due in June 1999, (vi) a $251,000 interest bearing note
at a rate of 7.51% per schedule payable in equal monthly installments of $8,000,
due in July 1999.

         The aggregate maturity of long-term debt for the five years ending
December 31 is: 1997, $5,292,000; 1998, $6,472,000; 1999, $6,252,000; 2000,
$4,313,000; 2001, $4,313,000; 2002 and thereafter, $31,622,000.

NOTE 8 - LEASES

         Future minimum lease payments under noncancelable operating leases
total $13,390,000, $10,203,000, $8,876,000, $7,419,000 and $4,733,000 for the
years ended December 31, 1997, 1998, 1999, 2000 and 2001, respectively. Lease
payments under noncancelable operating leases subsequent to the year ended
December 31, 2001 aggregate $7,637,000.

         On December 24, 1996, the Company entered into an agreement for the
sale and leaseback of the Company's self constructed thermal destruction unit
located at the Drake Chemical project in Lockhaven, Pennsylvania. The lease is a
one year lease with annual renewals at the option of the Company. The lease
calls for rental payments which total $3,214,000, $3,214,000, $3,214,000 and
$5,784,000 for the years ended December 31, 1997, 1998, 1999 and 2000,
respectively, with required early termination payments of $9,179,000, $6,962,000
or $5,956,000 in the event the lease is canceled on or before December 24, 1997,
1998 or 1999, respectively. The lease is classified as an operating lease in
accordance with Statement of Financial Accounting Standards No. 13, "Accounting
for Leases". The cost and accumulated depreciation of $11,579,000 and $4,181,000
were removed from the accounts and gain realized on the sale of $5,452,000 was
deferred. The deferred gain is being amortized to income as adjustments to lease
expense over the term of the lease.

         Rental expense under operating leases totaled $14,029,000, $8,858,000
and $5,906,000 for the years ended December 31, 1996, 1995 and 1994,
respectively.

         The valuation allowance for deferred tax assets is $12,970,000 and
$8,196,000 at December 31, 1996 and 1995, respectively. The change in valuation
allowance for the current year is due to the final purchase accounting
adjustments for the Rust acquisition recorded in the second quarter of 1996. The
increase in the valuation allowance reduces the net deferred tax asset recorded
from the acquisition of the Division. See "Note 2 - Acquisition." In the event
the valuation allowance is not required, a reduction to goodwill will occur in
accordance with SFAS No. 109.

NOTE 12 - CAPTIAL STOCK

         The Company has authorized 2,000,000 shares of preferred stock at a
$10.00 par value. No shares of preferred stock had been issued at December 31,
1996. The rights and preferences of the preferred stock will be fixed by the
Board of Directors at the time such shares are issued. The preferred stock, when
issued, will have dividend and liquidation preferences over those of the common
shareholders.

         In December 1993, the Company completed a public offering of 3,365,000
shares of common stock at $11.00 per share. Total net proceeds to the Company
from such offering were $34,963,000, less issuance expenses of $705,000, and
were used to reduce the outstanding amounts under the Company's revolving credit
agreement. In January 1994, the Company issued an additional 85,000 shares of
common stock at $11.00 per share which resulted in $883,000 of net proceeds,
less issuance expenses of $86,000, to the Company.

         On March 28, 1995, the Company sold to H. Wayne Huizenga and an
affiliated family foundation 1,000,000 shares of its common stock and options
for an aggregate purchase price of $10,000,000, less issuance expenses of
$25,000. The options are exercisable over five years for the purchase of 620,000
shares of common stock upon payment of $10.00 per share and 380,000 shares of
common stock upon payment of $12.00 per share.

         On May 30, 1995, the Company issued 9,668,000 shares of common stock in
exchange for substantially all of the assets and certain liabilities of the
hazardous and nuclear waste remediation service business of Rust. In addition,
the Company issued a warrant to purchase up to 700,000 shares of common stock at
an exercise price of $15.00 per share to Rust's parent company, WMX, in exchange
for a $62,000,000 guarantee of the Company's indebtedness by WMX. The warrant is
exercisable until May 30, 2000. See "Note 2 - Acquisition."

NOTE 13 - STOCK OPTION PLAN

         The Company has elected to follow APB No. 25 and related
interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under SFAS
No. 123 requires use of option valuation models that were not developed for use
in valuing employee stock options. Under APB No. 25, because the exercise price
of the Company's employee stock options equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.

         The Company's 1986 Incentive Stock Option Plan ("1986 Plan") as amended
by vote of the shareholders at the 1994 and 1996 Annual Meetings, has authorized
the grant of options to officers and key employees for up to 3,850,000 shares of
the Company's common stock. All options granted have 10 year terms and vest and
become fully exercisable at the end of up to 6 years of continued employment.
The number of shares available for grants of additional options under the 1986
Plan were 1,161,674 and 254,844 at December 31, 1996 and 1995, respectively.

         On August 6, 1992, the Company's Board of Directors approved a stock
option plan for the Board of Directors (the "Directors' Plan"), which was
subsequently approved by the Company's shareholders at the 1993 Annual Meeting.
The Directors' Stock Option Plan provides for the immediate grant to each
non-employee director a stock option for 15,000 shares of the Company's common
stock, less the number of shares held by any such director under the 1986 Stock
Option Plan. Additionally, the Directors' Plan provides for additional grants of
stock options for 5,000 shares of the Company's common stock, at prices not less
than the fair value, to each non-employee director annually. Options granted
under the Directors' Plan may not be exercised for a period of six months
following the date of grant and terminate up to eleven years after the date of
grant or eighteen months after the holder ceases to be a member of the Board of
Directors, whichever occurs earlier. The total number of shares available for
grants of additional options under the Directors' Plan at December 31, 1996 and
1995 was 805,000 and 850,000, respectively.

         On August 15, 1996, the Board of Directors of the Company approved the
OHM Corporation Incentive Stock Plan ("ISP") which permits the Board to grant
shares of common stock of the Company to officers of the Company under
restrictions set forth with the grant. Shares issued under the ISP are subject
to substantial risk of forfeiture within the meaning of Section 83 of the
Internal Revenue Code of 1986. There have been 105,000 shares of common stock
issued under the ISP with a vesting date of August 15, 2001 for 100% of the
shares.

         Pro forma information regarding net income and earnings per share is
required by SFAS No. 123, which also requires that the information be determined
as if the Company has accounted for its employee stock options granted
subsequent to December 31, 1994 under the fair value method of that Statement.
The fair value for these options was estimated at the date of grant using a
Black-Scholes option pricing model with the following weighted-average
assumptions for 1995 and 1996: risk-free interest rate of 6.0%; no dividend
yield; volatility factor of the expected market price of the Company's common
stock of 0.46; and a weighted-average expected life of each option of 7 years.

         The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

         For purposes of pro forma disclosures of net income and earnings per
share, the estimated fair value of the options is amortized to expense over the
options' vesting period. The Company's pro forma information follows:

</TABLE>

Because SFAS No. 123 is applicable only to options granted subsequent to
December 31, 1994, its pro forma effect will not be fully reflected until 1997.

NOTE 14 - RETIREMENT AND PROFIT-SHARING PLANS

         The Company has a Retirement Savings Plan (the "Plan") which allows
each of its eligible employees to make contributions, up to a certain limit, to
the Plan on a tax-deferred basis under Section 401(k) of the Internal Revenue
Code of 1986, as amended. Eligible employees are those who are employed
full-time, are over twenty-one years of age, and have one year of service with
the Company. The Company may, at its discretion, make matching contributions and
profit sharing contributions to the Plan out of its profits for the plan year.
The Company made matching contributions of $2,691,000, $1,643,000 and $1,225,000
to the Plan for the years ended December 31, 1996, 1995 and 1994, respectively.

         Effective January 1, 1996, the Board of Directors of the Company
approved the Retirement and Incentive Compensation Plan ("RICP") which provides
eligible employees an election to defer a specified percentage of their cash
compensation. The obligations of the Company under the RICP will be unsecured
general obligations to pay the deferred compensation under the terms of the
RICP. Participants may elect under the plan to invest deferrals in an OHM Common
Stock Deferral Account for which contributions will be treated as if such
amounts had been used to purchase shares of the Company's stock and not as
actual purchases of the Company's stock. At the discretion of the compensation
committee of the Board of Directors, contributions to the plan will be matched
by the Company and all amounts invested in the plan will earn interest at the
prime rate published by the Wall Street Journal if not invested in the OHM
Common Stock Deferral Account.

NOTE 15 - LITIGATION AND CONTINGENCIES

         The Company is currently in litigation in the U.S. District Court for
the Western District of Louisiana with Citgo Petroleum Corporation ("Citgo"),
Oxy USA Inc., and Occidental Oil & Gas (collectively "Oxy") relating to cost
overruns and production shortfalls on a remediation project which was performed
by the Company for Citgo at its Lake Charles, Louisiana refinery during 1993 and
1994. The Company has recorded in its financial statements approximately
$27,609,000 as a claim receivable and $5,381,000 of accounts receivable that are
in dispute for work performed under the terms of the Company's base contract
with Citgo. The Company is seeking damages in excess of $35,000,000. Citgo's
second amended complaint seeks damages under the contract for production
shortfalls, which Citgo has asserted in answer to the Company's interrogatories
to be approximately $27,600,000. The Company has filed a third party complaint
against Oxy for negligent misrepresentation and detrimental reliance as a result
of Oxy's involvement with the development of sample and analytical data relied
upon by the Company in preparation of its bid and cost estimates for work at the
Lake Charles refinery. In December 1996 and January 1997, Oxy and Citgo,
respectively, filed motions for summary judgment and partial summary judgment on
the Company's claims. The Company filed briefs in opposition to these motions.
These motions for summary judgment and partial summary judgment are still
pending.

         The Company is currently in litigation in the U.S. District Court for
the Western District of New York with Occidental Chemical Corporation
("Occidental") relating to the Durez Inlet Project performed in 1993 and 1994
for Occidental in North Tonawanda, New York. The Company's accounts receivable
at December 31, 1996 include a claim receivable of $8,618,000 related to this
matter. The Company's work was substantially delayed and its costs of
performance were substantially increased as a result of conditions at the site
which the Company believes were materially different than as represented by
Occidental. Occidental's amended complaint seeks $8,806,000 in damages primarily
for alleged costs incurred as a result of project delays and added volumes of
incinerated waste. The Company's counterclaim seeks an amount in excess of
$9,200,000 for damages arising from Occidental's breach of contract,
misrepresentation and failure to pay outstanding contract amounts.

         The Company is currently in arbitration proceedings with Separation and
Recovery Systems, Inc. ("SRS") resulting from SRS's failure to adequately
perform it's subcontract obligations to the Company for thermal desorption
services at the Hilton-Davis project in Cincinnati, Ohio. The Company's
financial statements on December 31, 1996 include a back charge receivable of
approximately $7,345,000 representing additional costs the Company has and will
incur as a result of completing SRS's scope of work under its thermal desorption
subcontract with the Company. SRS has filed a counterclaim against the Company
for approximatley $2,500,000 alleging wrongful termination of the subcontract.

         Management believes that it has established adequate reserves should
the resolution of the above matters be lower than the amounts recorded. There
is, however, always risk and uncertainty in pursuing and defending litigation
and arbitration proceedings in the course of the Company's business and,
notwithstanding the reserves currently established, adverse future results in
litigation or other proceedings could have a material adverse impact upon the
Company's consolidated future results of operations or financial condition.

         In addition to the above, the Company is subject to a number of claims
and lawsuits in the ordinary course of its business. In the opinion of
management, the outcome of these actions, which are not clearly determinable at
the present time, are either adequately covered by insurance or other reserves,
or if not insured or reserved, will not, in the aggregate, have a material
adverse impact upon the Company's consolidated financial position or the results
of future operations.

NOTE 16 - MAJOR CUSTOMERS

         Revenue from federal government agencies accounted for 72%, 71% and 55%
of total revenue from continuing operations for the years ended December 31,
1996, 1995 and 1994, respectively. Revenue from state and local government
agencies accounted for 5%, 5% and 10% of total revenue from continuing
operations for the years ended December 31, 1996, 1995 and 1994, respectively.
There were no industrial customers which accounted for more than 10% of total
revenue for the years ended December 31, 1996, 1995 and 1994.

NOTE 17 - SPECIAL CHARGES

         The Company's consolidated statement of operations for the year ended
December 31, 1995 includes a $2,312,000 (net of $1,542,000 income tax benefit)
or $0.10 per share, charge for integration costs related to the acquisition of
the Division. The charge was recorded as a selling, general and administrative
expense and was primarily for severance and relocation costs

                                       37


<PAGE>   40



for certain of the Company's personnel and the closing of certain of the
Company's offices as a result of combining the operations of the Division and
the Company.

         The Company's consolidated statement of operations for the year ended
December 31, 1994 included a special charge of $15,000,000 (net of $10,000,000
income tax benefit) or $0.96 per share, to establish a reserve for accounts
receivable, primarily where such accounts are in litigation. Such charge was
recorded as a reduction of revenue.

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors and Shareholders
OHM Corporation

         We have audited the accompanying consolidated balance sheets of OHM
Corporation and subsidiaries as of December 31, 1996 and 1995, and the related
consolidated statements of operations, changes in shareholders' equity, and cash
flows for each of the three years in the period ended December 31, 1996. Our
audits also included the financial statement schedule listed in the Index at
Item 14(a). These financial statements and schedule are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements and schedule based on our audits.

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

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
OHM Corporation and subsidiaries at December 31, 1996 and 1995, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1996, in conformity with generally
accepted accounting principles. Also, in our opinion, the related financial
statement schedule, when considered in relation to the basic financial
statements taken as a whole, presents fairly in all material respects the
information set forth therein.

                                                               ERNST & YOUNG LLP

from which Obligee or Obligor could reasonably and in good faith infer that such
event might occur; (ii) there shall not have occurred since the date specified
as the Financial Condition Reference Date on the Related Exhibit A for such
Item, any event which, in the reasonable judgment of the Obligee or Obligor, has
had a material adverse effect on the properties, executive management (taken as
a whole), condition (financial or otherwise), operations or business of the
Obligor taken as a whole or the Guarantor taken as a whole; (iii) such Item of
Equipment is acceptable to Obligee, and is free of all Liens, other than any
Lien specifically excepted in Section 15 hereof; (iv) the Acceptance Date for
such Item of Equipment is a date within the Acquisition Period specified on the

Obligee the Related Exhibit A for such Item; (v) the Equipment Cost of such Item
of Equipment, when added to the total Equipment Cost of all Equipment of the
type to which such Item relates and which has been financed hereunder, or
ordered by Obligor for financing hereunder, will not be such an amount so as to
cause the Maximum Equipment Cost specified on the Related Exhibit A for such
Item to be exceeded; (vi) Obligee has received an invoice for such Item of
Equipment from the seller thereof, approved for payment by Obligor, showing
Obligor as the purchaser of an interest in such Item, or, if Obligor is the
seller of an interest in such Item, a receipt for the transfer of such interest
from Obligor to Obligee in form and substance satisfactory to Obligee, together
with an appraisal report delivered to and satisfactory in form and substance to
the Obligee, demonstrating that the Equipment Cost of such Item is equal to the
current fair market value thereof, and, if requested by the Obligee, evidence,
satisfactory to Obligee, that Obligee has satisfied all payment obligations
incurred in connection with its original acquisition of such Item, (vii) Obligee
has received a Supplement for such Item, duly executed by Obligor, and dated the
Acceptance Date for such Item; (viii) all filings or recordings of such
documents as shall be necessary or advisable in order to establish and perfect
Obligee's or any Assignee's interest in the Equipment as against Obligor and/or

authority, and a copy of the manufacturer's statement or certificate of origin
therefor, reflecting Obligee or such Assignee as first lienholder; (ix) Obligee
shall have received the Cross Receipt and such other documents concerning the
Obligor and the Guarantor, appraisals, opinions, certificates and waivers, in
form and substance satisfactory to Obligee, as Obligee may


                                       7

require; and (x) Obligor shall have procured all licenses, registrations,
certificates, permits, approvals and consents required by Federal, state or
local laws or by any governmental body, agency or authority, and otherwise
complied with any Environmental Laws in connection with the ownership, delivery,
installation, use and operation of each Item of Equipment at its current
location.

         4. DELIVERY, ACCEPTANCE AND FINANCING OF EQUIPMENT. Obligee shall not
be liable to Obligor for any failure or delay in obtaining any Item of Equipment
or making delivery thereof. Forthwith upon delivery of each Item of Equipment to
Obligor, Obligor will inspect such Item, and unless Obligor gives Obligee prompt
written notice of any defect in or other proper objection to such Item, Obligor
shall promptly upon completion of such inspection execute and deliver to Obligee
a Supplement for such Item, dated the Acceptance Date of such Item. The
execution by Obligee and Obligor of a Supplement for an Item of Equipment shall
(a) evidence that such Item is financed under, and is subject to all of the
terms, provisions and conditions of, this Agreement, and (b) constitute
Obligor's unconditional and irrevocable acceptance of such Item for all purposes
of this Agreement. An Item of Equipment shall be conclusively deemed to relate
to the particular numbered Exhibit A now or hereafter attached hereto and made a
part hereof on which is set forth (i) a description of such Item or the type of
Equipment to which such Item relates and (ii) the Acquisition Period within
which the Acceptance Date for such Item has occurred.

         5. TERM. The Basic Term for each Item of Equipment shall commence on
the Basic Term Commencement Date thereof and, unless this Agreement is sooner
terminated with respect to such Item (or all Equipment) pursuant to the
provisions hereof, shall end on the date specified therefor in the Supplement
for such Item. If not sooner terminated pursuant to the provisions hereof, the
Term for each Item of Equipment shall end on the last day of the Basic Term
thereof, or if this Agreement is renewed pursuant to Section 28(a) hereof, on
the last day of the last Renewal Term thereof.

         6.       END OF TERM DELIVERY OF EQUIPMENT.

         (a) Upon the expiration or earlier termination of the Term with respect
to each Item of Equipment (unless Obligor has exercised its purchase option with
respect to Obligee's interest therein pursuant to Section 28(b) hereof), Obligor
will, at its expense, surrender and deliver possession of each Item of Equipment
to Obligee at such location within the continental United States as shall be
designated by Obligee in writing, or, in the absence of such designation, at the
then location of each such Item. At the time of such delivery to Obligee, each
Item of Equipment (and each part or component thereof) shall (i) be in good
operating order, and in the repair and condition as when originally delivered to
Obligor, ordinary wear and tear from proper use thereof excepted, (ii) be
capable (including, without 



                                       8

<PAGE>   9

limitation, in respect of its packaging and labeling) of being immediately
assembled and operated by a third party purchaser or third party lessee without
further inspection, repair, replacement, alterations or improvements (excluding
third party peculiar requirements for compatibility with then existing third
party products, equipment or facilities, or compliance by such third party with
any applicable Environmental Laws), (iii) be in accordance and compliance with
any and all statutes, laws, ordinances, rules and regulations of any Federal,
state or local governmental body, agency or authority applicable to the use and
operation of such Item (including without limitation, Environmental Laws), (iv)
be capable of performing its originally intended functions within its original
manufacturer's specified tolerances, (v) be free of all Hazardous Materials,
contaminants, toxic chemicals and residue of any kind, (vi) be free and clear of
all Liens, other than any Lien granted or placed thereon by Obligee or any
Assignee. All de-installation of the Equipment shall be performed by technical
personnel acceptable to the Obligee. In addition to the foregoing, Obligor shall
be liable for and shall pay all costs and expenses of removing the Equipment
from the location thereof in accordance with Environmental Laws. If any Item of
Equipment is originally equipped with tires or mounted on Equipment with tires,
such Item or Equipment shall, in addition to satisfying the requirements of the
preceding sentence, be returned with all tires installed thereon, with each tire
having at least fifty percent (50%) or more tread remaining thereon, and with
each brake having at least fifty percent (50%) or more remaining brake life
thereon.

         (b) Until each such Item of Equipment has been delivered to Obligee in
the condition and as otherwise provided in this Section 6 (unless Obligor has
exercised its purchase option with respect to Obligee's interest therein
pursuant to Section 28(b) hereof), Obligor shall continue to pay Obligee, on the
same dates on which Basic Payments for such Item were payable during the Basic
Term thereof (or, if the Term of such Item has been renewed, the most recent
Renewal Term thereof), the same Basic Payments for such Item that were payable
on the last Payment Date of the Basic Term thereof, or if the Term of such Item
has been renewed pursuant to Section 28(a), the same Basic Payments that were
payable on the last Payment Date during the most recent Renewal Term.

         (c) The provisions of this Section 6 are of the essence of this
Agreement and upon application to any court of equity having jurisdiction in the
premises, Obligee shall be entitled to a decree against Obligor requiring
specific performance of the covenants of Obligor set forth in this Section 6.

         7.       PAYMENTS.

         (a) [intentionally omitted].


                                       9
<PAGE>   10

         (b) BASIC PAYMENTS. Obligor hereby agrees to pay Obligee Basic Payments
for each Item of Equipment during the Basic Term thereof at the times and on the
Payment Dates set forth on the Related Exhibit A for such Item and in an amount
obtained by multiplying (i) the Equipment Cost of such Item by (ii) the
percentage of Equipment Cost set forth (opposite the Basic Payment Percentage
reference) on such Related Exhibit A, as the same may be adjusted pursuant to
Related Exhibit A.

         (c) SUPPLEMENTAL PAYMENTS. Obligor also agrees to pay to Obligee, or to
whomsoever shall be entitled thereto as expressly provided herein, all
Supplemental Payments, promptly as the same shall become due and owing, and in
the event of any failure on the part of Obligor so to pay any such Supplemental
Payment hereunder Obligee shall have all rights, powers and remedies provided
for herein or by law or equity or otherwise in the case of nonpayment of Basic
Payments.

         (d) METHOD OF PAYMENT. All Basic Payments and Supplemental Payments
required to be made by Obligor to Obligee shall be made in immediately available
funds not later than 12:00 noon Eastern time. In the event of any assignment to
an Assignee pursuant to Section 14(b) hereof, all payments which are assigned to
such Assignee, whether Basic Payments, Supplemental Payments or otherwise, shall
be paid in such manner as shall be designated by Obligee or such Assignee. Time
is of the essence in connection with the payment of Basic Payments and
Supplemental Payments.

         Whenever any payment hereunder shall be stated to be due on a day which
is not a day on which banks are required to be open for business in Boston,
Massachusetts (a "Banking Day"), such payment shall be made on the next
succeeding Banking Day.

         8. NET FINANCING. This Agreement is a net financing agreement. Obligor
acknowledges and agrees that Obligor's obligations hereunder, including, without
limitation, its obligations to make Basic Payments for all Equipment financed
hereunder, to pay all Supplemental Payments payable hereunder and under each
other Obligor Document, shall be unconditional and irrevocable under any and all
circumstances, shall not be subject to cancellation, termination, modification
or repudiation by Obligor, and shall be paid and performed by Obligor without
notice or demand and without any abatement, reduction, diminution, setoff,
defense, counterclaim or recoupment whatsoever, including, without limitation,
any abatement, reduction, diminution, setoff, defense, counterclaim or
recoupment due or alleged to be due to, or by reason of, any past, present or
future claims which Obligor may have against Obligee, any Assignee, any
manufacturer or supplier of the Equipment or any part or Item thereof, or any
other Person for any reason whatsoever or any defect in the Equipment or any
part or Item thereof, or the condition, design, operation or fitness for use
thereof, or any damage to, or any loss or destruction of, the Equipment or any
part or Item thereof, any Liens or rights of 



                                       10

<PAGE>   11

others with respect to the Equipment or any part or Item thereof, or any
prohibition or interruption of or other restriction against Obligor's use,
operation or possession of the Equipment or any part or Item thereof, for any
reason whatsoever, or any interference with such use, operation or possession by
any Person or entity, or any default by Obligee in the performance of its
obligations herein contained, or any other indebtedness or liability, howsoever
and whenever arising, of Obligee, or of any Assignee, or of Obligor to any other
Person, or by reason of insolvency, bankruptcy or similar proceedings by or
against Obligee, any Assignee or Obligor, or for any other reason whatsoever,
whether similar or dissimilar to any of the foregoing, any present or future law
to the contrary notwithstanding; it being the intention of the parties hereto
that all Basic Payments and Supplemental Payments payable by Obligor hereunder
shall continue to be payable in all events and in the manner and at the times
herein provided, without notice or demand, unless the obligation to pay the same
shall be terminated pursuant to the express provisions of this Agreement.

         9. GRANT OF SECURITY INTEREST; EQUIPMENT TO BE AND REMAIN PERSONAL
PROPERTY. This Agreement is a financing intended as security. Obligor hereby
grants to Obligee a security interest in the Equipment, the Required
Alterations, the Optional Alterations and all proceeds thereof as collateral
security for the payment and performance by Obligor of Obligor's obligations as
Obligor hereunder. It is the intention and understanding of both Obligee and
Obligor, and Obligor shall take all such actions as may be required to assure,
that the Equipment shall be and at all times remain personal property,
notwithstanding the manner in which the Equipment may be attached or affixed to
realty. Obligor shall obtain and record such instruments and take such steps as
may be necessary to prevent any Person from acquiring any rights in the
Equipment by reason of the Equipment being claimed or deemed to be real
property. Upon request by Obligee, Obligor shall obtain and deliver to Obligee
valid and effective waivers, in recordable form, by the owners, landlords and
mortgagees of the real property upon which the Equipment or any Item of
Equipment is located or certificates of Obligor that it is the owner of such
real property or that such real property is not leased and/or mortgaged;
PROVIDED, that if an Item is located on a Site designated as a National Priority
Fund Site (or any similar designation) pursuant to applicable Environmental
Laws, the Obligee may in lieu of delivering waivers from owners, landlords or
mortgagees, deliver to the Obligee evidence, reasonably satisfactory to the
Obligee, of the Obligor's currently effective contractual arrangements with
respect to such Site, so long as such contractual arrangements do not provide
for any lien or security interest in such Item. Obligor shall cause each Item of
Equipment subject to motor vehicle titling and registration laws to be titled in
the name of Obligor, as owner, with Obligee or Assignee, as applicable to be
shown as sole lienholder, and shall cause all certificates of title to be
promptly furnished to Obligee.

                                       11
<PAGE>   12

         10. USE OF EQUIPMENT; COMPLIANCE WITH LAWS. Obligor agrees that the
Equipment will be used and operated solely in the conduct of its business and in
compliance with any and all Remediation Contracts, insurance policy terms,
conditions and provisions and with all statutes, laws, ordinances, rules and
regulations of any Federal, state or local governmental body, agency or
authority applicable to the use, management and operation of the Equipment,
including, without limitation, all applicable Environmental Laws (including
without limitation, those pertaining to the operation of dewatering equipment
and the disposal of any solid wastes resulting therefrom) and with the terms of
all Remediation Contracts, and will promptly rectify any noncompliance
therewith, and including, in the case of any Item subject to motor vehicle
titling and registration laws, all titles, registrations, registration plates,
permits, licenses, and all renewals thereof. Obligor shall procure and maintain
in effect all licenses, registrations, certificates, permits, approvals and
consents required by Federal, state or local laws or by any governmental body,
agency or authority in connection with the ownership, delivery, installation,
use and operation of each Item of Equipment, including without limitation, those
required by Environmental Laws. Obligor will use and maintain the Equipment in a
careful and proper manner, in accordance with all Remediation Contracts and the
manufacturer's or supplier's instructions or manuals, and only by competent and
duly qualified personnel authorized by Obligor. The Equipment will at all times
be and remain in the possession and control of Obligor; PROVIDED, that the
Obligor may for temporary periods not exceeding 30 days in length relinquish
possession and control of any Item to the manufacturer or to an independent
contractor, for purposes of repair or alteration required or permitted
hereunder. The Equipment shall in no event be located outside of the continental
limits of the United States. Obligor shall use every reasonable precaution to
prevent loss or damage to each Item of Equipment from fire and other hazards.

         10A. CERTAIN COVENANTS. All storage and use of Hazardous Substances in
connection with the Equipment, and the installation and de-installation of the
Equipment, shall be in strict compliance with Environmental Laws applicable
thereto. Obligor will promptly give written notice to Obligee of the occurrence
of any Event of Loss or Event of Default, of the commencement of any litigation
or proceedings affecting Obligor from time to time which, if adversely
determined, could have a material adverse effect on Obligor's business,
operations or financial condition taken as a whole or which could otherwise
affect the Equipment, or of any dispute between Obligor and any governmental
regulatory body or other party that involves any of the Equipment.

         In addition to the foregoing,

         (1) Obligor will promptly provide the Obligee with written
notice:


                                       12

         regarding the operations of the Equipment at a Site;

                  (d) upon the Obligor's obtaining knowledge of any potential or
         known Release, or threat of Release, of any Hazardous Material at or
         from the Equipment which it reports in writing or which is required to
         report in writing to any governmental authority or which could
         materially adversely affect the Obligor or the Equipment;

                  (e) upon the Obligor's receipt of any notice of violation or
         alleged violation of any Environmental Laws or of any Release or
         threatened Release of Hazardous Materials, including a notice or claim
         of liability or potential responsibility from any third party
         (including without limitation any federal, state or local governmental
         officials) and including notice of any formal inquiry, proceeding,
         demand, investigation or other action, with regard to (i) the
         Obligor's or any person's operation of the Equipment, (ii)
         contamination at or from the Equipment or (iii) investigation or
         remediation of offsite locations at which the Obligor or its
         predecessors are alleged to have directly or indirectly disposed of
         Hazardous Materials from a Site; or

                  (f) upon the Obligor's obtaining knowledge that any expense or
         loss has been incurred by such governmental authority in connection
         with the assessment, containment, removal or remediation of any
         Hazardous Materials at or from a Site, with respect to which the
         Obligor may be liable or for which a Lien may be imposed on the
         Equipment; or

                  (g) that Obligor is or shall be named party to any claim,
         action, cause of action, complaint, legal or administrative proceeding
         arising out of any third party's incurrence of costs, expenses, losses
         or damages of any kind whatsoever in connection with the Release of
         Hazardous Materials at or from a Site, or in excess of such costs and
         expenses payable or reimburseable under any Remediation Contract.

         In addition to the foregoing, Obligor will provide to Obligee:


                                       13
<PAGE>   14

                  (h) as soon as practicable after request by the Obligee from
         time to time, a written report of an investigation, conducted to the
         satisfaction of the Obligee, by a consultant to be selected or approved
         by the Obligee, as to any significant environmental, health or safety
         violations, hazards or liabilities to which Obligor or Guarantor may be
         subject in respect of the Equipment or a Site;

                  (i) promptly and in any event within five Business Days after
         receipt thereof by Obligor or Guarantor, a copy of each notice,
         citation or other communication from the United States Environmental
         Protection Agency, any state environmental protection agency, any court
         or other governmental Person, and of each consent agreement, consent
         decree, judgment or other document with any such Person, in each case
         asserting an actual or potential violation, fine, penalty, enforcement
         action or liability of Obligor or Guarantor under any Environmental
         Laws in respect of the Equipment or a Site, or otherwise if the effect
         or adverse determination thereof would reasonably have a materially
         adverse effect on the properties, condition (financial or otherwise),
         operations or business of Obligor and of Guarantor taken as a whole.

                  (2) except in accordance with Environmental Laws and as
         set forth in any Remediation Contract:

                           (i) no portion of the Equipment has been or will
                  be used for the handling, processing, storage or
                  disposal of Hazardous Materials;

                           (ii) neither Obligor nor any of its subcontractors
                  have released or will release any Hazardous Materials
                  at or from a Site; and

                           (iii) there have been and will be no unpermitted
                  Releases or threatened Releases which would result in a lien
                  upon such Equipment; and there have been and will be no
                  unpermitted Releases or threatened Releases by Obligor or any
                  of its subcontractors which would reasonably have a material
                  adverse effect on the environment or the value of the property
                  at or in the vicinity of a Site;

                  (3) if any unpermitted Release or Disposal of Hazardous
         Materials shall occur or shall have occurred as a result of the
         operation of the Equipment not in accordance with Environmental Laws,
         Obligor shall cause the prompt containment and removal of such
         Hazardous Materials and remediation of a Site as necessary to comply
         with all Environmental Laws or to preserve the value of the Equipment;

                                       14
<PAGE>   15

                  (4) Obligor will at all times maintain in effect any
         indemnification of Obligee contained in any Remediation Contract, and
         will maintain such insurance, performance bonds, or other financial
         assurance as is required by applicable law or reasonably required by
         the Obligee or by any Remediation Contract; and

                  (5) any Hazardous Materials that will be handled by the
         Equipment or that will be generated by the Equipment, to the best
         knowledge of Obligor, will be transported offsite only by carriers
         having an identification number issued by the EPA, treated or disposed
         of only by treatment or disposal facilities maintaining valid permits
         as required under applicable Environmental Laws, which transporters and
         facilities will be to the best knowledge of the Obligor, operating in
         compliance with such permits and applicable Environmental Laws.

         11.      MAINTENANCE AND REPAIR OF EQUIPMENT.  Obligor agrees,
at its own cost and expense, to keep, repair, maintain and preserve the
Equipment in good order and operating condition, and in compliance with such
maintenance and repair standards and procedures as are set forth in the
manufacturer's manuals pertaining to the Equipment, and as otherwise may be
required to enforce warranty claims against each vendor and manufacturer of each
Item of Equipment, and in compliance with all Remediation Contracts and
requirements of law applicable to the maintenance and condition of the
Equipment, including, without limitation, environmental, noise and pollution
laws and regulations (including notifications and reports). Obligor shall, at
its own cost and expense, supply the necessary power and other items required in
the operation of the Equipment. Obligor hereby waives any right now or hereafter
conferred by law to make repairs on the Equipment at the expense of Obligee.

         12.      REPLACEMENTS; ALTERATIONS; MODIFICATIONS;
SUBSTITUTIONS.

         (a) In case any Item of Equipment (or any equipment, part or appliance
therein) is required to be altered, added to, replaced or modified in order to
comply with any laws, regulations, requirements or rules ("Required Alteration")
pursuant to Sections 10 or 11 hereof, Obligor agrees to make such Required
Alteration at its own expense and an interest in the same shall immediately vest
in Obligee and the same shall be subject to the terms of this Agreement. Obligor
may make any optional alteration to any Item of Equipment ("Optional
Alteration") provided such Optional Alteration does not impair the value, use or
remaining useful life of such Item of Equipment. An interest in such Optional
Alteration shall be immediately vested in Obligee and the same shall be subject
to this Agreement. Obligor agrees that, within 30 days after the close of any
calendar quarter in which Obligor has made any Required Alterations that could
have an adverse effect upon the value, utility or useful 



                                       15

<PAGE>   16

life of any Item of Equipment, Obligor will give written notice thereof to
Obligee describing, in reasonable detail, the Required Alterations and
specifying the cost thereof with respect to such Item of Equipment and the date
or dates when made. Any parts installed or replacements made by Obligor upon any
Item of Equipment pursuant to its obligation to maintain and keep the Equipment
in good order, operating condition and repair under Section 11 hereof shall be
considered accessions to such Item of Equipment and an interest therein shall be
immediately vested in Obligee and the same shall be subject to this Agreement.
Except as required or permitted by the provisions of this Section 12, Obligor
shall not modify an Item of Equipment without the prior written authority and
approval of Obligee.

          (b) With the prior written consent of Obligee, not to be unreasonably
withheld, Obligor shall be permitted to substitute for any Item of Equipment
then subject to this Agreement (provided that, in Obligor's good faith opinion,
as evidenced by a certificate of its President, treasurer or chief financial
officer, such Item shall have become no longer useful, or surplus, to Obligor in
its business), like kind equipment having a fair market value and utility equal
to or greater than such Item. Such fair market value and utility shall be
determined by the Obligee in its reasonable discretion. If such substitution is
permitted by the Obligee, the item of equipment so substituted shall be
considered an "Item of Equipment" subject to this Agreement and the interest of
the Obligee hereunder, and Obligor shall execute such documents as may be
reasonably requested by Obligee to evidence its interest therein, and Obligee's
rights and interests in, to and under the item of equipment having been so
substituted shall be terminated and Obligee shall execute and deliver to Obligor
a transfer and release of its interest in such item to Obligor, "as is where is"
without representation or warranty of any kind.

         13. IDENTIFICATION MARKS; INSPECTION. Obligor agrees, upon the request
of Obligee, at Obligor's sole cost and expense, to place markings on the
Equipment by stencil or by a metal tag or plate affixed thereto showing plainly,
distinctly and conspicuously Obligee's security interest therein; provided,
however, that such identification markings are to be placed so as not to
interfere with the usefulness of such Item of Equipment. If during the Term any
such identification marking shall at any time be defaced or destroyed, Obligor
shall immediately cause such defaced or destroyed identification marking to be
restored or replaced. Obligor shall not allow the name of any Person to be
placed upon any Item of Equipment as a designation which might be interpreted as
indicating a claim of a security interest therein by any Person other than
Obligee or any Assignee. Upon the request of Obligee, Obligor shall make the
Equipment available to Obligee for inspection and shall also make Obligor's
records pertaining to the Equipment available to Obligee for inspection.

         14.      ASSIGNMENTS AND SUBLEASING.

         (a) BY OBLIGOR. EXCEPT IN CONNECTION WITH A TRANSACTION PERMITTED BY
SECTIONS 12(b) or 14(c) AND TEMPORARY RELINQUISHMENTS OF POSSESSION PERMITTED BY
SECTION 10, OBLIGOR SHALL NOT, WITHOUT THE PRIOR WRITTEN CONSENT OF OBLIGEE,
SUBLEASE OR OTHERWISE RELINQUISH POSSESSION OF ANY ITEM OF EQUIPMENT, OR ASSIGN,
TRANSFER OR ENCUMBER ITS RIGHTS, INTERESTS OR OBLIGATIONS HEREUNDER AND ANY
ATTEMPTED SUBLEASE, RELINQUISHMENT, ASSIGNMENT, TRANSFER OR ENCUMBERING BY
OBLIGOR SHALL BE NULL AND VOID.

         (b)  BY OBLIGEE.  Obligee may, at any time, without notice
to, or the consent of, Obligor sell, assign or transfer or grant a security
interest in all or any part of Obligee's rights, obligations, title or interest
in, to and under the Equipment or any Item(s) thereof, this Agreement, any
Supplement and/or any Basic Payments and Supplemental Payments payable under
this Agreement or any Supplement to any leasing or finance company, bank,
insurance company or other financial institution. Any entity to whom any such
sale, assignment, transfer or grant of security interest is made is herein
called an "Assignee" and any such sale, assignment, transfer or grant of
security interest is herein called an "assignment". An Assignee may re-assign
and/or grant a security interest in any of such rights, obligations, title or
interest assigned to such Assignee. Obligor agrees to execute such related
amendments to this Agreement, such acknowledgments and other documents that may
be reasonably requested by Obligee or an Assignee and that do not, taken as a
whole, materially and adversely affect the interest of Obligor in the
transactions contemplated by this Agreement. Each Assignee shall have and may
enforce all of the rights and benefits of Obligee hereunder with respect to the
Item(s) of Equipment and related Supplement(s) covered by the assignment,
including, without limitation, the provisions of Section 8 hereof and Obligor's
representations and warranties under Section 21 hereof. Each such assignment
shall be subject to Obligor's rights hereunder so long as no Event of Default
has occurred and is occurring hereunder. Obligor shall be under no obligation to
any Assignee except upon written notice of such assignment from Obligee or, in
the case of a reassignment, from the Assignee. Upon written notice to Obligor of
any such assignment, Obligor agrees to pay the Basic Payments and Supplemental
Payments with respect to the Item(s) of Equipment covered by such assignment to
such Assignee in accordance with the instructions specified in such notice
without any abatement, defense, setoff, counterclaim or recoupment whatsoever,
and to otherwise comply with all notices, directions and demands which may be
given by Obligee or such Assignee with respect to such Item(s), in accordance
with the provisions of this Agreement. Notwithstanding any such assignment, all
obligations of Obligee to Obligor under this Agreement shall be and remain
enforceable by Obligor against Obligee and any Assignee to whom an assignment
hereunder has been made.

         (c)  CONSOLIDATIONS AND MERGERS BY OBLIGOR.  OBLIGOR SHALL NOT
CONSOLIDATE WITH OR MERGE INTO ANY OTHER CORPORATION OR CONVEY, TRANSFER OR
LEASE SUBSTANTIALLY ALL OF ITS ASSETS AS AN ENTIRETY TO ANY PERSON UNLESS:

                  (I) THE CORPORATION FORMED BY SUCH CONSOLIDATION OR INTO WHICH
         OBLIGOR IS MERGED, OR THE PERSON WHICH ACQUIRES BY CONVEYANCE, TRANSFER
         OR LEASE SUBSTANTIALLY ALL OF THE ASSETS OF OBLIGOR AS AN ENTIRETY,
         SHALL BE A SOLVENT CORPORATION ORGANIZED AND EXISTING UNDER THE LAWS OF
         THE UNITED STATES OF AMERICA OR ANY STATE OR THE DISTRICT OF COLUMBIA
         AND SHALL EXECUTE AND DELIVER TO OBLIGEE AND EACH ASSIGNEE AN AGREEMENT
         CONTAINING AN EFFECTIVE ASSUMPTION BY SUCH SUCCESSOR, TRANSFEREE OR
         LESSEE CORPORATION OF THE DUE AND PUNCTUAL PERFORMANCE AND OBSERVANCE
         OF EACH COVENANT AND CONDITION OF THIS EQUIPMENT AGREEMENT; PROVIDED
         ANY LEASE OF SUBSTANTIALLY ALL OF ITS ASSETS SHALL NOT RELEASE OBLIGOR
         FROM ITS OBLIGATIONS UNDER THIS EQUIPMENT AGREEMENT, WHICH OBLIGATIONS 
         SHALL AT ALL TIMES REMAIN PRIMARY AND DIRECT;

                  (II) IMMEDIATELY AFTER GIVING EFFECT TO SUCH TRANSACTION, NO
         EVENT OF DEFAULT, AND NO EVENT WHICH, AFTER NOTICE OR LAPSE OF TIME, OR
         BOTH, WOULD BECOME AN EVENT OF DEFAULT, SHALL HAVE OCCURRED AND BE
         CONTINUING;

                  (III) IMMEDIATELY AFTER GIVING EFFECT TO SUCH TRANSACTION, THE
         TANGIBLE NET WORTH (HEREINAFTER DEFINED) OF THE CORPORATION FORMED BY
         SUCH CONSOLIDATION OR INTO WHICH OBLIGOR IS MERGED OR THE PERSON WHICH
         ACQUIRED BY CONVEYANCE, TRANSFER OR LEASE SUBSTANTIALLY ALL THE ASSETS
         OF OBLIGOR AS AN ENTIRETY, AS THE CASE MAY BE, SHALL NOT BE LESS THAN
         THE TANGIBLE NET WORTH OF OBLIGOR AS REFLECTED IN THE THEN MOST RECENT
         OF OBLIGOR'S LATEST CERTIFIED FINANCIAL STATEMENTS FURNISHED BY OBLIGOR
         PURSUANT TO SECTION 30 HEREOF PRIOR TO SUCH CONSOLIDATION, MERGER,
         CONVEYANCE, TRANSFER OR LEASE; AND

                  (IV) OBLIGOR SHALL HAVE DELIVERED TO OBLIGEE, AND ASSIGNEE A
         CERTIFICATE SIGNED BY TWO OFFICERS, ONE OF WHOM SHALL BE THE PRESIDENT
         OR A VICE PRESIDENT, AND ONE OF WHOM SHALL BE THE TREASURER OR THE
         SECRETARY OR AN ASSISTANT SECRETARY OF OBLIGOR, AND AN OPINION
         SATISFACTORY IN FORM AND SUBSTANCE TO THE ADDRESSEES THEREOF OF
         OBLIGOR'S COUNSEL, EACH STATING THAT SUCH CONSOLIDATION, MERGER,
         CONVEYANCE, TRANSFER OR LEASE AND THE ASSUMPTION AGREEMENT MENTIONED IN
         CLAUSE (I) ABOVE COMPLIES WITH THIS SECTION 14(c) AND THAT ALL
         CONDITIONS PRECEDENT HEREIN PROVIDED FOR RELATING TO SUCH TRANSACTION
         HAVE BEEN COMPLIED WITH.

         UPON ANY CONSOLIDATION OR MERGER, OR ANY CONVEYANCE, TRANSFER OR LEASE
OF SUBSTANTIALLY ALL THE ASSETS OF OBLIGOR AS AN ENTIRETY IN ACCORDANCE WITH
THIS SECTION 14(c), THE SUCCESSOR CORPORATION FORMED BY SUCH CONSOLIDATION OR
INTO WHICH OBLIGOR IS MERGED OR TO WHICH SUCH CONVEYANCE, TRANSFER OR LEASE IS
MADE 


                                       18

<PAGE>   19

SHALL SUCCEED TO, AND BE SUBSTITUTED FOR (BUT WITHOUT RELEASE OF OBLIGOR TO
THE EXTENT THE PROVISION TO CLAUSE (I) ABOVE IS APPLICABLE), AND MAY EXERCISE
EVERY RIGHT AND POWER OF, OBLIGOR UNDER THIS EQUIPMENT AGREEMENT WITH THE SAME
EFFECT AS IF SUCH SUCCESSOR CORPORATION HAD BEEN NAMED AS A OBLIGOR HEREIN. FOR
PURPOSES OF THIS SECTION 14(c) "TANGIBLE NET WORTH" MEANS THE TOTAL OF THE PAR
VALUE OF COMMON STOCK AND ANY CLASS OR SERIES OF PREFERRED STOCK (AFTER
DEDUCTION FOR TREASURY STOCK), ADDITIONAL PAID-IN CAPITAL, GENERAL CONTINGENCY
RESERVES AND RETAINED EARNINGS OR DEFICIT, DETERMINED IN ACCORDANCE WITH
GENERALLY ACCEPTED ACCOUNTING PRINCIPLES, MINUS THE FOLLOWING ITEMS (WITHOUT
DUPLICATION OF DEDUCTIONS), IF ANY, APPEARING ON THE BALANCE SHEET: (I) THE BOOK
VALUE OF ALL ASSETS (INCLUDING, WITHOUT LIMITATION, GOODWILL) WHICH WOULD BE
TREATED AS INTANGIBLES UNDER GENERALLY ACCEPTED ACCOUNTING PRINCIPLES; AND
(II) ANY WRITE-UP IN THE BOOK AMOUNT OF ANY EXISTING ASSET RESULTING FROM A
RE-EVALUATION THEREOF FROM THE BOOK AMOUNT ENTERED UPON ACQUISITION IN EXCESS OF
THAT PERMITTED UNDER GENERALLY ACCEPTED ACCOUNTING PRINCIPLES.

         15.      LIENS. Obligor will not directly or indirectly create, incur,
assume or suffer to exist any Lien on or with respect to (i) the Equipment or
any part or Item thereof, Obligee's interest therein, or (ii) any of Obligee's
interests in, to or under this Agreement, except any Lien granted or placed
thereon by Obligee or any Assignee. Obligor, at its own expense, will promptly
pay, satisfy and otherwise take such actions as may be necessary to keep this
Agreement and the Equipment free and clear of, and to duly discharge or
eliminate or bond in a manner satisfactory to Obligee and each Assignee, any
such Lien not excepted above if the same shall arise at any time. Obligor will
notify Obligee and each Assignee in writing promptly upon becoming aware of any
tax or other Lien (other than any lien excepted above) that shall attach to the
Equipment or any Item of Equipment, and of the full particulars thereof.

         16.      LOSS, DAMAGE OR DESTRUCTION.

         (a) RISK OF LOSS, DAMAGE OR DESTRUCTION. Obligor hereby assumes all
risk of loss, damage, theft, taking, destruction, confiscation, requisition or
commandeering, partial or complete, of or to each Item of Equipment, however
caused or occasioned, such risk to be borne by Obligor with respect to each Item
of Equipment from the date of this Agreement, and continuing until such Item of
Equipment has been delivered to Obligee in accordance with the provisions of
Section 6 hereof or Obligee's interest therein has been purchased by Obligor in
accordance with the provisions of Section 28 hereof. Obligor agrees that no
occurrence specified in the preceding sentence shall impair, in whole or in
part, any obligation of Obligor under this Agreement, including, without
limitation, the obligation to pay Basic Payments.

                                       19
<PAGE>   20

         (b) PAYMENT OF CASUALTY LOSS VALUE UPON AN EVENT OF LOSS. If an Event
of Loss occurs with respect to an Item of Equipment during the Term thereof,
Obligor shall give Obligee prompt written notice thereof and shall pay to
Obligee on the Casualty Loss Value Payment Date next following the date of such
Event of Loss (or on the last day of the Term if there is no succeeding Casualty
Loss Value Payment Date) the sum of (i) all unpaid Basic Payments payable for
such Item of Equipment for any Payment Period prior to the Payment Period in
which the Event of Loss has occurred, plus (ii) (x) if Basic Payments for such
Item of Equipment are payable in advance, the Casualty Loss Value of such Item
of Equipment determined as of the Casualty Loss Value Payment Date next
preceding or coincident with the date of such Event of Loss, plus the Basic
Payment payable for such Item for the Payment Period in which such Event of Loss
has occurred if such Basic Payment was not paid on the Payment Date therefor, or
(y) if Basic Payments for such Item are payable in arrears, the Casualty Loss
Value of such Item of Equipment determined as of the Casualty Loss Value Payment
Date next following the date of such Event of Loss, plus the Basic Payment
payable for such Item of Equipment for the Payment Period in which such Event of
Loss has occurred if such Casualty Loss Value Payment Date for such Item is a
Payment Date, plus (iii) all other Supplemental Payments due for such Item of
Equipment as of the date of payment of the amounts specified in the foregoing
clauses (i) and (ii), for such Item determined as of the Casualty Loss Value
Payment Date. Any payments received at any time by Obligee or by Obligor from
any insurer or other party (except Obligor) as a result of the occurrence of
such Event of Loss will be applied in reduction of Obligor's obligation to pay
the foregoing amounts, if not already paid by Obligor, or, if already paid by
Obligor, will be applied to reimburse Obligor for its payment of such amount,
unless an Event of Default shall have occurred and be continuing. Upon payment
in full of such Casualty Loss Value, Basic Payments and Supplemental Payments,
(A) the obligation of Obligor to make Basic Payments hereunder with respect to
such Item of Equipment shall terminate and the Term of such Item shall
terminate, and (B) Obligor shall, as agent for Obligee, as soon as practicable,
dispose of such Item or Items of Equipment in a manner reasonably acceptable to
Obligee.

         (c) APPLICATION OF BASIC PAYMENTS NOT RELATING TO AN EVENT OF LOSS. Any
payments (including, without limitation, insurance proceeds) received at any
time by Obligee or Obligor from any governmental authority or other party with
respect to any loss or damage to any Item or Items of Equipment not constituting
an Event of Loss, will be applied directly in payment of repairs or for
replacement of property in accordance with the provisions of Section 11 and 12
hereof, if not already paid by Obligor, or if already paid by Obligor and no
Event of Default shall have occurred and be continuing, shall be applied to
reimburse Obligor for such payment, and any balance remaining after compliance
with the provisions of said Sections with respect to such loss or damage shall
be retained by Obligor.

                                       20
<PAGE>   21

         17. INSURANCE. Obligor will cause to be carried and maintained, at its
sole expense, with respect to the Equipment at all times during the Term thereof
and until the Equipment has been delivered to Obligee (a) physical damage
insurance insuring against all risks of physical loss or damage to the
Equipment, in an amount not less than the greater of the Casualty Loss Value of
the Equipment or the replacement value of the Equipment, and (b) comprehensive
insurance against general liability for bodily injury, death and property damage
resulting from the use and operation of the Equipment in an amount not less than
$10,000,000 per occurrence, in each case with exclusions and deductibles
acceptable to Obligee and no greater than those applicable to insurance on
similar equipment owned or operated by Obligor, and (c) contractor's pollution
liability insurance in an amount not less than $7,500,000 per occurrence or such
higher amount as Obligee may, at any time reasonably request, in each case with
exclusions and deductibles acceptable to Obligee and no greater than those
applicable to insurance on similar equipment owned or operated by Obligor. Such
insurance policy or policies will name Obligee and each Assignee as the loss
payees, as their interests may appear, on all policies referred to in clause (a)
of the preceding sentence, and will name Obligee and each Assignee as additional
insureds on all policies referred to in clause (b) of the preceding sentence.
Such policies will provide that the same may not be invalidated against Obligee
or any Assignee by reason of any violation of a condition or breach of warranty
of the policies or the application therefor by Obligor, that the policies may be
cancelled or materially altered or reduced in coverage (except as otherwise
permitted under the terms of this Agreement) by the insurer only after thirty
(30) days' prior written notice to Obligee and each Assignee, and that the
insurer will give written notice to Obligee and each Assignee in the event of
nonpayment of premium by Obligor when due. The policies of insurance required
under this Section shall be valid and enforceable policies issued by insurers of
recognized responsibility acceptable to Obligee and each Assignee and authorized
to do an insurance business in the state in which each Item of Equipment is
located. In the event that any of such policies referred to in clause (b) of the
first sentence of this Section shall now or hereafter provide coverage on a
"claims-made" basis, Obligor shall continue to maintain such policies in effect
for a period of not less than three (3) years after the expiration of the Term
of the last Item of Equipment under this Agreement. Upon the execution of this
Agreement and thereafter not less than thirty (30) days prior to the expiration
dates of any expiring policies theretofore furnished under this Section,
certificates of the insurance coverage required by this Section and, if
requested by Obligee or any Assignee, copies of the policies evidencing such
insurance coverage, shall be delivered by Obligor to Obligee and each other
named loss payee and/or additional insured. Any certificate of insurance issued
with respect to a blanket policy covering other equipment not subject to this
Agreement shall specifically describe the Equipment as being included therein
and covered thereby to the 


                                       21

<PAGE>   22

full extent of the coverages and amounts required hereunder. If Obligor shall
fail to cause the insurance required under this Section to be carried and
maintained, Obligee or any Assignee may provide such insurance and Obligor shall
reimburse Obligee or any such Assignee, as the case may be, upon demand for the
cost thereof as a Supplemental Payment hereunder.

         18.      GENERAL TAX INDEMNITY.  Obligor agrees to pay, defend
and indemnify and hold Obligee, each Assignee and their respective successors
and assigns harmless on an after-tax basis from any and all Federal, state,
local and foreign taxes, fees, withholdings, levies, imposts, duties,
assessments and charges of any kind and nature whatsoever, together with any
penalties, fines or interest thereon (herein called "taxes or other
impositions") howsoever imposed, whether levied or imposed upon or asserted
against Obligee, any Assignee, Obligor, the Equipment, any Item of Equipment, or
any part thereof, by any Federal, state or local government or taxing authority
in the United States, or by any taxing authority or governmental subdivision of
a foreign country, upon or with respect to (a) the Equipment, or any Item of
Equipment or any part thereof, (b) the manufacture, construction, ordering,
purchase, ownership, delivery, financing, leasing, subleasing, re-leasing,
possession, use, maintenance, registration, re-registration, titling,
re-titling, licensing, documentation, delivery, repossession, sale or other
application or disposition of the Equipment, or any Item of Equipment or any
part thereof, (c) the rentals, receipts or earnings arising from the Equipment
or any Item of Equipment or any part thereof, or (d) this Agreement, each other
Obligor Document, the Basic Payments and/or Supplemental Payments payable by
Obligor hereunder and any amounts payable by Obligor under any other Obligor
Document; provided, however, that the foregoing indemnity shall not apply to any
taxes or other impositions based upon or measured solely by Obligee's or any
Assignee's net income, and which are imposed or levied by any Federal, state or
local taxing authority in the United States. Obligor will promptly notify
Obligee of all reports or returns required to be made with respect to any tax or
other imposition with respect to which Obligor is required to indemnify
hereunder, and will promptly provide Obligee with all information necessary for
the making and timely filing of such reports or returns by Obligee. Obligor will
prepare and file the same if permitted by applicable law to file the same, or if
not so permitted, Obligor shall prepare such reports or returns for signature by
Obligee, and shall forward the same, together with immediately available funds
for payment of any tax or other imposition due, to Obligee, at least ten (10)
days in advance of the date such payment is to be made. Upon written request,
Obligor shall furnish Obligee with copies of all paid receipts or other
appropriate evidence of payment for all taxes or other impositions paid by
Obligor pursuant to this Section 18. All of the indemnities contained in this
Section 18 shall continue in full force and effect notwithstanding the
expiration or earlier termination of this Agreement in whole or in part,
including the expiration or 


                                       22

<PAGE>   23

termination of the Term with respect to any Item (or all) of the Equipment, and
are expressly made for the benefit of, and shall be enforceable by, Obligee and
each Assignee.

         19.      INDEMNIFICATION.

         (a) Obligor hereby assumes liability for, and does hereby agree to
indemnify, protect, save, defend, and hold harmless Obligee, each Assignee, and
their respective officers, directors, stockholders, successors, assigns, agents
and servants (each such party being herein, for purposes of this Section 19,
called an "indemnified party") on an after-tax basis from and against any and
all obligations, fees, liabilities, losses, damages, penalties, claims, demands,
actions, suits, judgments, costs and expenses, including legal expenses, of
every kind and nature whatsoever, imposed on, incurred by, or asserted against
any indemnified party, in any way relating to or arising out of (i) the
manufacture, construction, ordering, purchase, acceptance or rejection,
ownership, titling or retitling, registration or re-registration, delivery,
financing, leasing, subleasing, re-leasing, possession (other than by Obligee or
any Assignee), use (other than by Obligee or any Assignee), operation (other
than by Obligee or any Assignee), storage, removal, delivery, return,
repossession, sale or other disposition of the Equipment or any Item of
Equipment, or any part thereof, including, without limitation, any of such as
may arise from (A) loss or damage to any property or death or injury to any
persons, (B) patent or latent defects in the Equipment (whether or not
discoverable by Obligor or any indemnified party), (C) any claims based on
absolute or strict liability in tort, (D) any claims based on patent, trademark,
tradename or copyright infringement; or (ii) any failure on the part of Obligor
to perform or comply with any of the terms of this Agreement or any other
Obligor Document, and (E) any towing charges, parking tolls, fines, parking and
speeding tickets, odometer certifications and other civil and criminal motor
vehicle violations with respect to any such Item; and all penalties and interest
applicable to any of the foregoing, except as set forth in the exception to
Section 23(a) hereof in the case of any repossession of the Equipment. Obligor
shall give each indemnified party prompt notice of any occurrence, event or
condition known to Obligor as a consequence of which any indemnified party may
be entitled to indemnification hereunder. Obligor shall forthwith upon demand of
any such indemnified party reimburse such indemnified party for amounts expended
by it in connection with any of the foregoing or pay such amounts directly.
Obligor shall be subrogated to an indemnified party's rights in any matter with
respect to which Obligor has actually reimbursed such indemnified party for
amounts expended by it or has actually paid such amounts directly pursuant to
this Section 19. In case any action, suit or proceeding is brought against any
indemnified party in connection with any claim indemnified against hereunder,
such indemnified party will, promptly after receipt of notice of the
commencement of such action, suit or proceeding, notify Obligor thereof,

                                       23

<PAGE>   24

enclosing a copy of all papers served upon such indemnified party, but failure
to give such notice or to enclose such papers shall not relieve Obligor from any
liability hereunder. Obligor may, and upon such indemnified party's request
will, at Obligor's expense, resist and defend such action, suit or proceeding,
or cause the same to be resisted or defended by counsel selected by Obligor and
reasonably satisfactory to such indemnified party and in the event of any
failure by Obligor to do so, Obligor shall pay all costs and expenses
(including, without limitation, attorney's fees and expenses) incurred by such
indemnified party in connection with such action, suit or proceeding.

         (b) To the full extent permitted by applicable law, the Obligor hereby
agrees to defend, indemnify and hold harmless the Obligee, any Assignee and each
of their respective affiliates and directors, officers, employees and agents
from and against any and all loss, cost, expense or liability (including all
costs of legal representation and all fines or penalties) incurred in connection
with any and all claims or proceedings (whether brought by private party or
governmental agencies) for bodily injury, property damage, abatement or
remediation, environmental damage or impairment or any other injury or damage
resulting from or relating to any Hazardous Material located upon or migrating
into, from or through the property of the Obligor (including without limitation,
the Equipment)(whether or not the release of such Hazardous Materials was caused
by any of such Persons, a tenant or subtenant or a prior owner or tenant on any
such property and whether or not the alleged liability is attributable to the
handling, storage, generation, remediation, transportation or disposal of such
substance or the mere presence of the substance on any such property), which any
such indemnified party may incur due to acquisition of its interest in the
Equipment, the financing of the Equipment for Obligor, the exercise of any of
its rights under this Agreement (except, in the event of any foreclosure upon
and repossession of the Equipment, to the extent caused by the gross negligence
or willful misconduct of Obligee or its agents), or otherwise, including without
limitation, any loss, cost, expense or liability relating to (i) any Release or
threatened Release of any Hazardous Material at a Site (other than a release
which is permitted pursuant to applicable Environmental Laws), (ii) any
violation of any Environmental Laws with respect to conditions at a Site or the
operations conducted thereon, or (iii) the investigation or remediation of
offsite locations at which Obligor or its predecessors are alleged to have
directly or indirectly Disposed of Hazardous Materials from a Site.

                  (c) The provisions of this Section 19, and the obligations of
Obligor under this Section 19, shall apply from the date of the execution of
this Agreement notwithstanding that the Term may not have commenced with respect
to any Item of Equipment, and shall survive and continue in full force and
effect notwithstanding the expiration or earlier termination of this Agreement
in whole or in part, including the expiration of 


                                       24

<PAGE>   25

termination of the Term with respect to any Item (or all) of the Equipment and
any foreclosure or any modification, release or discharge or any or all of the
obligations of Obligor under this Agreement, and are expressly made for the
benefit of, and shall be enforceable by, each indemnified Person.

         20. NO WARRANTIES. OBLIGEE HEREBY FINANCES THE EQUIPMENT FOR OBLIGOR
AS-IS AND OBLIGEE EXPRESSLY DISCLAIMS AND MAKES NO REPRESENTATION OR WARRANTY,
EITHER EXPRESSED OR IMPLIED, AS TO THE DESIGN, CONDITION, QUALITY, CAPACITY,
MERCHANTABILITY, DURABILITY, SUITABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE
OF, OR ANY OTHER MATTER CONCERNING, THE EQUIPMENT. OBLIGOR HEREBY WAIVES ANY
CLAIM (INCLUDING ANY CLAIM BASED ON STRICT OR ABSOLUTE LIABILITY IN TORT OR
INFRINGEMENT) IT MIGHT HAVE AGAINST OBLIGEE FOR ANY LOSS, DAMAGE (INCLUDING
INCIDENTAL OR CONSEQUENTIAL DAMAGE) OR EXPENSE CAUSED BY THE EQUIPMENT OR BY
OBLIGOR'S LOSS OF USE THEREOF FOR ANY REASON WHATSOEVER, INCLUDING COMPLIANCE
WITH ENVIRONMENTAL LAWS. So long and only so long as an Event of Default shall
not have occurred and be continuing, and so long and only so long as the
Equipment shall be subject to this Agreement and Obligor shall be entitled to
possession of the Equipment hereunder, Obligee authorizes Obligor, at Obligor's
expense, to assert for Obligee's account, all rights and powers of Obligee under
any manufacturer's, vendor's or dealer's warranty on the Equipment or any part
thereof; provided, however, that Obligor shall indemnify, protect, save, defend
and hold harmless Obligee from and against any and all claims, and all costs,
expenses, damages, losses and liabilities incurred or suffered by Obligee in
connection therewith, as a result of, or incident to, any action by Obligor
pursuant to the foregoing authorization.

         21. OBLIGOR'S REPRESENTATIONS AND WARRANTIES. Obligor hereby represents
and warrants that (a) Obligor is a corporation duly organized, validly existing
and in good standing under the laws of its state of incorporation set forth
above, and is qualified to do business in, and is in good standing in, each

Equipment or any part thereof will be located); (b) Obligor has the corporate

Document and to finance the Equipment hereunder and thereunder, and has duly

Obligor, and (iii) will not violate or constitute a breach of any provision of
law, any order of any court or other agency of government, or any indenture,

a breach of, or constitute (with due notice and/or lapse of time) a default
under any such indenture, agreement or instrument, or result in the creation or
imposition of any Lien upon any of Obligor's property or assets; (d) this
Agreement and each other Obligor Document have each been executed by the duly
authorized officer or officers of Obligor and delivered to Obligee and
constitutes, and when executed by the duly authorized officer or officers of
Obligor and delivered to Obligee each Supplement and related instruments,
documents and agreements with respect to each Item of Equipment will constitute,
the legal, valid and binding obligations of Obligor, enforceable in accordance

Agreement, or if required, such consent has been obtained and forwarded to
Obligee; (f) no mortgage, deed of trust, or other Lien which now covers or
affects, or which may hereafter cover or affect, any property or interest

corporate reorganization, except in accordance with Section 14(c) and the
Guaranty; or

         (f) any representation, warranty, statement or certification made by
Obligor under this Agreement or in any Supplement or in any document or
certificate furnished Obligee or any Assignee in connection herewith or pursuant

Default and at any time thereafter so long as the same shall be continuing,
Obligee may exercise one or more of the following remedies as Obligee in its
sole discretion shall elect:

         (a) Obligee may terminate or cancel this Agreement, without prejudice
to any other remedies of Obligee hereunder, with respect to all or any Item of
Equipment, and whether or not this Agreement has been so terminated or
cancelled, may enter the premises of Obligor or any other party to take
immediate possession of the Equipment and remove all or any Item of Equipment by
summary proceedings or otherwise, or may cause Obligor, at Obligor's expense, to
store, maintain, surrender and deliver possession of the Equipment or such Item
in the same manner as provided in Section 6 hereof, all without liability to
Obligee for or by reason of such entry or taking of possession, whether for the
restoration of damage to property caused by such 


                                       29

<PAGE>   30

taking or otherwise, except to the extent caused by the gross negligence or
willful misconduct of Obligee or its agents;

         (b) Obligee may hold, keep idle or lease to others the Equipment or any
Item of Equipment, as Obligee in its sole discretion may determine, free and
clear of any rights of Obligor and without any duty to account to Obligor with
respect to such action or inaction or for any proceeds with respect thereto,
except that Obligor's obligation to make Basic Payments for any Payment Periods
commencing after Obligor shall have been deprived of possession pursuant to this
Section 23 shall be reduced by the net proceeds, if any, received by Obligee
from leasing the Equipment or such Item to any Person other than Obligor for the
same Payment Periods or any portion thereof;

         (c) Obligee may sell the Equipment or any Item of Equipment at public
or private sale as Obligee may determine, free and clear of any rights of
Obligor, and Obligor shall pay to Obligee, as liquidated damages for loss of a
bargain and not as a penalty (in lieu of the Basic Payment due for the Equipment
or Item(s) so sold for any Payment Period commencing after the date on which
such sale occurs), the sum of (i) all unpaid Basic Payments payable for each
Item of Equipment for all Payment Periods through the date on which such sale
occurs, plus (ii) an amount equal to the excess, if any, of (x) the Casualty
Loss Value of the Equipment or Item(s) so sold, computed as of the Payment Date
coincident with or next preceding the date of such sale, over (y) the net
proceeds of such sale, plus interest at the rate specified in Section 25 hereof
on the amount of such excess from the Payment Date as of which such Casualty
Loss Value is computed until the date of actual payment, plus (iii) all unpaid
Supplemental Payments due with respect to each Item of Equipment so sold,
including a Reinvestment Premium, computed as of the Payment Date coincident
with or next preceding the date of such sale; and

         (d) whether or not Obligee shall have exercised, or shall thereafter at
any time exercise, any of its rights under subsection (a) or (b) above with
respect to any Item(s) of Equipment, Obligee, by written notice to Obligor
specifying a payment date, may demand that Obligor pay to Obligee, and Obligor
shall pay to Obligee, on the payment date specified in such notice, as
liquidated damages for loss of a bargain and not as a penalty (in lieu of the
Basic Payment due for any Item(s) of Equipment for any Payment Period commencing
after the payment date specified in such notice and in lieu of the exercise by
Obligee of its remedies under subsection (b) above in the case of a re-lease of
such Item(s) or under subsection (c) above with respect to a sale of such
Item(s)), the sum of (i) all unpaid Basic Payments payable for such Item(s) for
all Payment Periods through the payment date specified in such notice, plus (ii)
all unpaid Supplemental Payments due with respect to such Item(s) as of the
payment date specified in such notice, including a Reinvestment Premium computed
as of the payment date specified in 


                                       30

<PAGE>   31

such notice, plus (iii) an amount, with respect to each such Item, equal to the
Casualty Loss Value of such Item(s) computed as of the Payment Date coincident
with or next preceding the payment date specified in such notice; provided,
however, that in the event of a sale of any such Item(s) delivered to or
repossessed by Obligee, if Obligor has paid in full the amounts described in
this paragraph Obligee shall refund to Obligor the aggregate Net Proceeds of
Sale of such Item(s) of Equipment as defined in Section 29(d)(ii); and

         (e) Obligee may exercise any other right or remedy which may be
available to it under applicable law or proceed by appropriate court action to
enforce the terms hereof or to recover damages for the breach hereof or to
rescind this Agreement.

         At any sale pursuant to this Section 23, the purchaser shall take the
Equipment free and clear of all rights and interest of Obligor in the Equipment.

         In addition, Obligor shall be liable for all costs and expenses,
including attorney's fees, incurred by Obligee or any Assignee by reason of the
occurrence of any Event of Default or the exercise of Obligee's remedies with
respect thereto, including all costs and expenses incurred in connection with
the delivery of the Equipment in accordance with Section 6 hereof or in placing
the Equipment in the condition required by said Section including, without
limitation, decontamination expenses. Except as otherwise expressly provided
above, no remedy referred to in this Section 23 is intended to be exclusive, but
each shall be cumulative and in addition to any other remedy referred to above
or otherwise available to Obligee at law or in equity; and the exercise or
beginning of exercise by Obligee of any one or more of such remedies shall not
constitute the exclusive election of such remedies and shall not preclude the
simultaneous or later exercise by Obligee of any or all of such other remedies.
No express or implied waiver by Obligee of any Event of Default shall in any way
be, or be construed to be, a waiver of any future or subsequent Event of
Default. To the extent permitted by applicable law, Obligor hereby waives any
rights now or hereafter conferred by statute or otherwise which may require
Obligee to sell, lease or otherwise use the Equipment in mitigation of Obligee's
damages as set forth in this Section or which may otherwise limit or modify any
of Obligee's rights and remedies in this Section 23.

         24. OBLIGEE'S RIGHT TO PERFORM FOR OBLIGOR. If Obligor fails to make
any Supplemental Payment required to be made by it hereunder or fails to perform
or comply with any of its agreements contained herein, Obligee may itself, after
notice to Obligor, make such payment or perform or comply with such agreement,
and the amount of such payment and the amount of the reasonable expenses of
Obligee incurred in connection with such payment or the performance of or
compliance with such agreement, 


                                       31
<PAGE>   32

as the case may be, together with interest thereon at the rate specified in
Section 25 hereof, shall, if not paid by Obligor to Obligee on demand, be deemed
a Supplemental Payment hereunder; PROVIDED, HOWEVER, that no such payment,
performance or compliance by Obligee shall be deemed to cure any Event of
Default hereunder.

         25. LATE CHARGES. Obligor shall pay to Obligee, upon demand interest on
any Basic Payment not paid when due, and on any Supplemental Payment or other
amount payable under this Agreement which is not paid when due, for any period
for which any of the same is overdue (without regard to any grace period) at a
rate equal to the lesser of (a) nine and 76/100 percent (9.76%) per annum, or
(b) the maximum rate of interest permitted by law.

         26. FURTHER ASSURANCES. Obligor will promptly and duly execute and
deliver to Obligee and any Assignee such other documents and assurances,
including, without limitation, such amendments to this Agreement as may be
reasonably required by Obligee and by any Assignee, and Uniform Commercial Code
financing statements and continuation statements (it being understood and agreed
that such financing statements and continuation statements will not be requested
for a jurisdiction other than those in which the chief executive office of the
Obligor is located or a jurisdiction in which a mobile filter press is located),
and will take such further action as Obligee or any Assignee may from time to
time reasonably request in order to carry out more effectively the intent and
purposes of this Agreement and to establish and protect the rights and remedies
created or intended to be created in favor of Obligee and of any Assignee and
their respective rights and interests in and to the Equipment.

         27. NOTICES. All notices provided for or required under the terms and
provisions hereof shall be in writing, and any such notice shall be deemed given
when personally delivered or when deposited in the United States mails, with
proper postage prepaid, for first class certified mail, return receipt
requested, addressed (i) if to Obligee or Obligor, at their respective addresses
as set forth herein or at such other address as either of them shall, from time
to time, designate in writing to the other, and (ii) if to any Assignee, to the
address of such Assignee as such Assignee shall designate in writing to Obligee
and Obligor.

         28. OBLIGOR'S RENEWAL AND PURCHASE OPTIONS; THIRD PARTY SALE.

         (a) OBLIGOR'S RENEWAL OPTION. If (i) no Event of Default shall have
occurred and be continuing and (ii) this Agreement shall not have been earlier
terminated, Obligor shall be entitled, at its option, to renew this Agreement
with respect to all, but not less than all, Items of Equipment then subject to

                                       32
<PAGE>   33

this Agreement for the Renewal Term(s) specified on the Related Exhibit A for
such Item. The first Renewal Term with respect to each such Item of Equipment
will commence at the expiration of the Basic Term of such Item, and each
succeeding Renewal Term will commence at the expiration of the next preceding
Renewal Term. All of the provisions of this Agreement, including the Basic
Payment Percentage, shall be applicable during each Renewal Term for each such
Item of Equipment, except that Basic Payments during each Renewal Term shall be
payable at the times and on the Payment Dates set forth on said Related Exhibit
A. If Obligor intends not to exercise said renewal option with respect to any of
said Renewal Terms, Obligor shall give written notice to Obligee to such effect
at least one hundred eighty (180) days prior to the expiration of the Basic Term
of the Item(s) of Equipment whose Basic Term first expires hereunder, in the
case of the first Renewal Term, and at least one hundred eighty (180) days prior
to the expiration of the then current Renewal Term of the Item(s) of Equipment
whose Basic Term first expires hereunder, in the case of the then next
succeeding Renewal Term. If Obligor fails to give such written notice to Obligee
with respect to any of said Renewal Terms, it shall be conclusively presumed
that Obligor has elected to exercise said renewal option with respect to said
Renewal Term. In the event Obligor elects not to exercise said renewal option
(unless Obligee has otherwise agreed in writing or Obligor has exercised its
purchase option under Section 28(b) hereof) each such Item of Equipment shall be
delivered to Obligee in accordance with the provisions of Section 6(a) hereof
(unless delivered to a bidder in accordance with Section 28(c) hereof) and until
each such Item has been so delivered Obligor shall continue to pay Obligee the
Basic Payments for each such Item as specified in Section 6(b) hereof.

         (b) OBLIGOR'S PURCHASE OPTION. If (i) no Event of Default shall have
occurred and be continuing, and (ii) this Agreement shall not have been earlier
terminated, Obligor shall be entitled, at its option, upon written notice to
Obligee, as hereinafter provided, to purchase Obligee's interest in all, but not
less than all, Items of Equipment then subject to this Agreement, on the
Termination Date for each such Item of Equipment, for an amount (the "Purchase
Option Amount"), with respect to each Item of Equipment, payable in immediately
available funds, equal to the sum of (w) the Estimated Residual Value of such
Item of Equipment applicable to the Basic Term or Renewal Term thereof then
ending, plus (x) the Basic Payment due and payable for such Item of Equipment on
the Termination Date, if Basic Payments for such Item are payable in arrears,
plus (y) any applicable sales, excise or other taxes imposed as a result of such
sale (other than gross or net income taxes attributable to such sale), plus (z)
any Supplemental Payments then due and owing to Obligee hereunder including, in
the event that Obligor exercises its purchase option hereunder prior to the end
of the Maximum Term, the Reinvestment Premium. Obligee's sale of its interest in
each Item of Equipment shall be on an as-is, where-is basis, without any
representation or warranty by, or recourse to, 


                                       33
<PAGE>   34

Obligee. If Obligor intends to exercise said purchase option, Obligor shall give
written notice to Obligee to such effect at least one hundred eighty (180) days
prior to the expiration of the Basic Term of the Item(s) of Equipment whose
Basic Term first expires hereunder, or, if Obligor has renewed this Agreement
pursuant to Section 28(a) hereof, then at least one hundred eighty (180) days
prior to the expiration of the then current Renewal Term of the Item(s) of
Equipment whose Basic Term first expires hereunder. If Obligor gives such
written notice to Obligee same shall constitute a binding obligation of Obligor
to purchase Obligee's interest in all of such Items of Equipment and to pay
Obligee the Purchase Option Amount on the Termination Date thereof.

         (c)  THIRD PARTY SALE OF EQUIPMENT.

                  (i) REMARKETING OBLIGATIONS. In the event Obligor does not
exercise either its option to renew this Agreement or to purchase Obligee's
interest in the Equipment pursuant to this Section, then Obligor shall have the
obligation during the last one hundred eighty (180) days of the Basic Term, or
the then current Renewal Term, if applicable (the "Remarketing Period"), to
obtain bona fide bids for Obligee's interest in not less than all Items of
Equipment then subject to this Agreement from prospective purchasers who are
financially capable of purchasing such interest for cash on an as-is, where-is
basis, without recourse or warranty. All bids received by Obligor prior to the
end of the Basic Term, or Renewal Term if applicable, of such Item(s) of
Equipment shall be immediately certified to Obligee in writing, setting forth
the amount of such bid and the name and address of the person or entity
submitting such bid. Notwithstanding the foregoing, Obligee shall have the
right, but not the obligation, to seek bids for its interest in the Equipment
during the Remarketing Period.

                  (ii)  SALE OF OBLIGEE'S INTEREST IN THE EQUIPMENT TO
THIRD PARTY BUYER. On the Termination Date, provided that all the conditions
hereof have been met, Obligee shall sell (or cause to be sold) its interest in
all Items of Equipment then subject to this Agreement, for cash to the bidder,
if any, who shall have submitted the highest bid during the Remarketing Period
on an as-is, where-is basis and without recourse or warranty, and upon receipt
by Obligee of the sales price Obligee shall instruct Obligor to deliver and
Obligor shall deliver such Item(s) of Equipment to such bidder; PROVIDED, that
(x) any such sale to a third party shall be consummated, and the sales price for
Obligee's interest in such Item shall be paid to Obligee in immediately
available funds, on or before the Termination Date; and (y) Obligee shall not be
obligated to sell its interest in such Equipment (I) if the Net Proceeds of Sale
of its interest in such Item(s) is less than the aggregate Maximum Obligee Risk
Amount applicable to such Item(s) as of the Termination Date or (II) if Obligee
has not received the amounts, if any, payable by Obligor pursuant to Section
29(a) and, if applicable, Section 


                                       34
<PAGE>   35

29(c). Such third party purchaser shall take the Equipment free and clear of all
rights and interest of Obligor in the Equipment.

         29.      END OF TERM ADJUSTMENT.

         (a) THIRD PARTY SALE OF EQUIPMENT. This Section 29(a) shall apply only
if, with respect to any Item(s) of Equipment, a sale of Obligee's interest in
such Item(s) to a third party pursuant to Section 28(c) hereof has been
consummated on the Termination Date. If the Net Proceeds of Sale of Obligee's
interest in such Item(s) is less than the aggregate Estimated Residual Value of
such Item(s) as of such Termination Date, Obligor shall, on the Termination
Date, pay to Obligee as an End of Term Adjustment, in immediately available
funds, an amount equal to such deficiency (a "Deficiency") as an adjustment to
the Basic Payments payable under this Agreement for such Item, plus the Basic
Payment due and payable for such Item(s) of Equipment on the Termination Date,
if Basic Payments for such Item(s) are payable in arrears, plus any Supplemental
Payments then due and owing to Obligee hereunder; PROVIDED, HOWEVER, that if no
Event of Default or event which, with notice or passage of time or both would
constitute an Event of Default, shall have occurred and be continuing hereunder,
the amount of the Deficiency payable by Obligor with respect to such Item(s)
shall not exceed the aggregate Maximum Obligor Risk Amount then applicable to
such Item(s). If the Net Proceeds of Sale of such Item(s) of Equipment exceeds
the aggregate Estimated Residual Value of such Item(s) and if no Event of
Default or event which, with notice or passage of time or both would constitute
an Event of Default, shall have occurred and be continuing hereunder and Obligor
shall have paid Obligee on or before the Termination Date the Basic Payment due
and payable for such Item(s) of Equipment on the Termination Date, if Basic
Payments for such Item(s) are payable in arrears, plus all Supplemental Payments
then due and owing with respect to such Item(s), plus any amounts due pursuant
to Section 29(c) hereof, Obligee shall pay to Obligor an amount equal to such
excess as an adjustment to the Basic Payments payable under this Agreement for
such Item(s).

         (b) OBLIGOR PAYMENT. If a sale of Obligee's interest in all Items of
Equipment then subject to this Agreement either to the Obligor pursuant to
Section 28(b) hereof or to a third party pursuant to Section 28(c) hereof has
not been consummated on the Termination Date with respect thereto for any
reason, then the Obligor shall, on the Termination Date of such Items, pay to
Obligee as an End of Term Adjustment, in immediately available funds, as an
adjustment to the Basic Payments payable under this Agreement for such Items, an
amount equal to (i) the Maximum Obligor Risk Amount of all of such Items, if on
the Termination Date no Event of Default or event which, with notice or passage
of time or both would constitute an Event of Default, shall have occurred and be
continuing hereunder, or (ii) the Estimated Residual Value of all of such Items,
if on the Termination Date an Event of Default or event which, with notice or
passage of 


                                       35

<PAGE>   36

time or both would constitute an Event of Default, shall have occurred and be
continuing hereunder, plus, in either case, the Basic Payments due and payable
for such Item(s) of Equipment on the Termination Date, if Basic Payments for
such Item(s) are payable in arrears, plus all Supplemental Payments then due and
owing with respect to such Item(s). Obligor shall remain liable for the payment
of, and upon the consummation by Obligee of the sale of Obligee's interest in
any Item(s) of Equipment after the Termination Date thereof, Obligor shall pay,
or reimburse Obligee for the payment of, any applicable sales, excise or other
taxes imposed as a result of such sale, other than gross or net income taxes
attributable to such sale, and such obligation shall survive the termination of
this Agreement.

         (c) REINVESTMENT PREMIUM. In the event a Termination Date of any Item
of Equipment occurs prior to the last day of the Maximum Term hereof relating to
such Item, Obligor shall pay to Obligee on the Termination Date of such Item in
immediately available funds, in addition to any other obligations hereunder, the

         31. EXPENSES. Obligor agrees, whether or not the transactions
contemplated by this Agreement are consummated, to pay (or reimburse Obligee or
any Assignee for the payment of) fees for lien searches, filing fees, fees and
expenses relating to the titling and registration of any Items of Equipment, and
all legal fees and expenses of Obligee (other than such legal fees and expenses
relating to the initial preparation of this Agreement) and all reasonable legal
fees and expenses of any Assignee, incurred by or on behalf of Obligee or any
Assignee in connection with the negotiation and documentation of this Agreement
and each other Obligor Document, the Guaranty, the further assurances described
herein, and the transactions contemplated hereby and thereby.

         32. OWNER FOR INCOME TAX PURPOSES. Obligee agrees that Obligor shall be
deemed the owner of the Equipment for federal, 


                                       37
<PAGE>   38

state and local income tax purposes and that, so long as no Event of Default
shall have occurred and be continuing, Obligee shall take no action inconsistent
with such ownership for income tax purposes.

         33. VOLUNTARY TERMINATION FOR OBSOLESCENCE. So long as no Event of
Default shall have occurred and be continuing hereunder, Obligor shall have the
right at its option on any Payment Date during the Basic Term or any Renewal
Term, on at least ninety (90) days' prior written notice to and with the prior
written consent of Obligee (not to be unreasonably withheld), to terminate this
Equipment Agreement with respect to any Item of Equipment then subject to this
Agreement if, in Obligor's good faith opinion, as evidenced by a certificate of
its President, treasurer or chief financial officer, such Item shall have become
no longer useful, or surplus, to Obligor in its business, with such termination
to be effective on the Payment Date specified in such notice (for purposes of
this Section 33, called the "termination date"). During the period from the
giving of such notice until the date thirty (30) days prior to the termination
date, Obligor, as agent for Obligee, shall use its reasonable efforts (but no
less effort than used to sell equipment Obligor owns itself) to secure the
highest obtainable bids for the purchase of Obligee's interest in such Item and
in the event it receives any bid during such period, Obligor shall promptly
certify to Obligee in writing the amount and terms of such bid and the name and
address of the party submitting such bid. On the termination date (but in no
event prior to Obligee's receipt of the amounts specified in the next succeeding
sentence), Obligor shall deliver possession of such Item to the bidder, if any,
which shall have submitted the highest bid during such period, and Obligee
shall, without recourse or warranty, simultaneously therewith transfer its
interest in such Item on an "as-is", "where-is" basis for cash to such bidder.
The total transfer price realized at such sale shall be paid to and retained by
Obligee and, in addition, on the termination date Obligor shall pay to Obligee
the sum of the amounts specified in sub-clauses (i) through (v): (i) the Basic
Payment due and payable for such Item on the termination date, plus (ii) all
accrued and unpaid Basic Payments owing for such Item for all Payment Periods
prior to the Payment Period for which the Basic Payment specified in the
preceding sub-clause (i) is payable, plus (iii) the excess, if any, of the
Termination Value of such Item as of the Payment Date coincident with the
termination date, over the aggregate proceeds of sale of Obligee's interest in
such Item, after deducting from such proceeds of sale the expenses incurred by
Obligee in connection with such sale, plus (iv) any sales or excise taxes on or
measured by such sale, plus (v) all accrued and unpaid Supplemental Payments
owing by Obligor as of the termination date, including a Reinvestment Premium
for such Item determined as of such termination date. Neither Obligor nor any
person, firm or corporation, affiliated with Obligor, may purchase the
Equipment, or after any such sale, lease or otherwise utilize the Equipment. If
no sale shall have occurred


                                       38
<PAGE>   39

on or as of the termination date, this Equipment Agreement (including the
provisions of this Section 33) shall continue in full force and effect with
respect to the Equipment. In the event of any such sale and the receipt by
Obligee of the amounts described above, and upon compliance by Obligor with the
provisions of this Section 33, the obligations of Obligor to make Basic Payments
hereunder with respect to each item of Equipment so sold shall cease for any
Payment Period that commences on or after the termination date and the Term with
respect to each such Item of Equipment shall end effective as of the termination
date. Obligee may, but shall be under no duty to, solicit bids, inquire into the
efforts of Obligor to obtain bids or otherwise take any action in connection
with any such sale other than the duty to transfer to the purchaser named in the
highest bid certified by Obligor to Obligee, without recourse or warranty, on an
"as-is", "where-is" basis, all of Obligee's interest in and to the Equipment so
sold against receipt by Obligee of the payments provided for herein. Anything
herein to the contrary notwithstanding, if Obligor shall exercise its said right
to termination as provided in this Section 33, Obligee may, in its sole
discretion, elect to receive delivery of all of the Equipment subject to said
notice by giving Obligor written notice to such effect within thirty (30) days
following Obligee's receipt of the written notice from Obligor hereinabove
provided, in which event (a) no sale shall occur pursuant to this Section 33,
(b) Obligor shall deliver the Equipment to Obligee in accordance with the
provisions of Section 6 hereof and shall continue to make Basic Payments for the
Equipment on each Payment Date to and inclusive of (and the Term of the
Equipment shall terminate on) the Payment Date next following the date on which
such delivery occurs.

         34. NO RELIANCE. Obligor hereby acknowledges that in negotiating the
terms of this Agreement and all other related agreements and documents, it has
sought, obtained and relied exclusively upon such accounting, actuarial, tax and
legal advice from its own or other independent sources as it has deemed
necessary, and further acknowledges that neither Obligee nor any of Obligee's
parent, subsidiaries, affiliates or personnel has represented or warranted the
legal, tax economic, accounting, or other consequences of the terms and
provisions hereof and of the other related agreements and documents.

         35. MISCELLANEOUS. Any provision of this Agreement or any other Obligor
Document which is prohibited or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating or diminishing Obligee's rights under the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction. To the extent permitted by applicable law, Obligor hereby
waives any provision of law which renders any provision of this Agreement or any
other Obligor Document prohibited or unenforceable in any respect. No 


                                       39

<PAGE>   40

term or provision of this Agreement or any other Obligor Document may be
amended, altered, waived, discharged or terminated orally, but may be amended,
altered, waived, discharged or terminated only by an instrument in writing
signed by a duly authorized officer of the party against which the enforcement
of the

amendment, alteration, waiver, discharge or termination is sought. A waiver on
any one occasion shall not be construed as a waiver on a future occasion. All of
the covenants, conditions and obligations contained in this Agreement and each
other Obligor Document shall be binding upon and shall inure to the benefit of
the respective successors and assigns of Obligee and (subject to the
restrictions of Section 14(a) hereof) Obligor. This Agreement and the other
Obligor Documents collectively constitute the complete and exclusive statement
of the terms of the agreement between Obligee and Obligor with respect to the
financing of the Equipment, and cancel and supersede any and all prior oral or
written understandings with respect thereto.

Obligor's Initials

         36. VENUE; GOVERNING LAW. Obligor agrees that at Obligee's sole
election any suit, action or proceeding brought by Obligee against Obligor in
connection with or arising out of this Agreement or any other Obligor Document
may be brought in any federal court in the Commonwealth of Massachusetts, and
Obligor waives personal service of all process upon it and consents that service
of process may be made by mail or messenger directed to it at its address set
forth above and that service so made shall be deemed to be completed upon the
earlier of actual receipt or three (3) days after the same shall have been
posted to Obligor's said address. Nothing herein contained shall affect
Obligee's right to serve legal process in any other manner permitted by law or
to bring any suit, action or proceeding against Obligor or its property in the
courts of any other jurisdiction. This Agreement and each other Obligor Document
shall in all respects be governed by, and constructed in accordance with, the
laws of the Commonwealth of Massachusetts, including all matters of
construction, validity and performance.

         37. NO MERGER. There shall be no merger of this Equipment Agreement or
of any leasehold or subleasehold estate created hereby or pursuant hereto, with
the fee or any other estate or ownership or security interest in any Item of
Equipment, by reason of the fact that the same Person may acquire or own or
hold, directly or indirectly, (i) this Equipment Agreement or any leasehold or
subleasehold estate or security interest created hereby or hereunder, or any
other interest in this Equipment Agreement or any such lease or sublease or in
any such leasehold or subleasehold estate, and/or (ii) the fee estate or any
other estate or ownership or security interest, or any other interest, in any
Item of Equipment; and this Equipment Agreement shall not be terminated for any
reason except as expressly provided herein or as may be expressly agreed in
writing by the holders of the Obligor's and Obligee's respective interests, and
any instrument of transfer shall so provide.

(1)     Fully dilutive effect of stock options and warrants on per share
        amounts for the year ended December 31, 1994 were antidilutive. 
        Accordingly, fully diluted per share amounts were not presented
        in the Company's consolidated statements of operations.

(2)     Fully dilutive effect of stock options and warrants on per share amounts
        for the years ended December 31, 1996 and 1995 have not been presented
        in the statement of operations since any reduction of less than 3% in
        the aggregate need not be considered as dilution.
