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


   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


   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


   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

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.

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


   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


   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):

         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


   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


   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:



                                                                                          YEAR ENDED DECEMBER 31,

TWELVE MONTHS ENDED DECEMBER 31, 1996 VS. TWELVE MONTHS ENDED DECEMBER 31, 1995

         Revenue. The following table sets forth the Company's revenue by client
type for the twelve months ended December 31, 1996 and 1995 (in thousands,
except percentages):



                                                                 1996                     1995
                                                                 ----                     ----
                                                                                    
Federal, State, and Local Government                     $426,256      77%         $349,052      76%
Industrial                                                124,728      23           108,873      24
                                                        ---------    ----         ---------    ----
         Total Revenue                                   $550,984     100%         $457,925     100%
                                                         ========     ===          ========     ===


         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


   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.

         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


   20



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


   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


   29



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


   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.

December 31, 1995 and 1994 are based upon certain assumptions and estimates
which the Company believes are reasonable. The combined pro forma results of

have been reported had the transaction been consummated on January 1, 1994, nor
are they necessarily indicative of results which will be reported in the future.

at the date of acquisition are as follows (in thousands):

         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
$106,000 interest bearing note at a rate of 8.70% per schedule payable in equal
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

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:



                                                  Pro Forma
                                             Years Ended December 31,

                                             ----               ----
                                      (In Thousands, Except Per Share Data)

                                                            
Net income                                  $10,901            $6,428
Net income per share                        $  0.41            $ 0.29


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


   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.
