                                     PART I
 
ITEM 1. BUSINESS
 
GENERAL
 
  Safety-Kleen is a business-to-business marketing and service company focusing
on the environmental needs of business through recycling and reuse of fluid
waste. It is a leading provider of services to generators of spent solvents and
other hazardous and non-hazardous liquid wastes and byproducts, the world's
largest provider of parts cleaner services and one of the world's largest
collectors and re-refiners of used oil. The Company serves over 400,000
customers in North America and Europe, through a network of 236 branch
facilities.
 
  The Company operates in the continental U.S., Canada, the United Kingdom, the
Republic of Ireland, Puerto Rico, Belgium, France, Italy, Spain and Germany.
The Company has licensee operations in Israel, Japan, and Korea. Safety-Kleen
Corp. was incorporated in July, 1963 under the laws of the State of Wisconsin.
As used herein, the terms "Company" or "Safety-Kleen" refer to Safety-Kleen
Corp. and its consolidated subsidiaries.
 
  The Company groups its services into three broad categories: Small Quantity
Generator ("SQG") Resource Recovery Services, Envirosystems Services, and Oil
Recovery Services. Each of the Company's services is discussed in greater
detail below and in "Management's Discussion and Analysis of Financial
Condition and Results of Operations" appearing on pages 20-25 of the Company's
Annual Report to Shareholders for the year ended December 31, 1994 (the "Annual
Report"), which is incorporated herein by reference.
 
SQG RESOURCE RECOVERY SERVICES
 
  The Company's SQG Resource Recovery Services are divided into
Automotive/Retail Repair Services, Industrial Services, Paint Refinishing
Services, Dry Cleaner Services and Imaging Services. Solvent recycling is an
integral part of the Company's SQG Resource Recovery Services. Most fluid
wastes collected by the Company as part of these services, except Imaging
Services, are either recycled for re-use in these services or processed into
waste-derived fuel for use in the cement manufacturing industry. Imaging
Services recovers the silver contained in the spent photochemical solutions it
collects from customers. These solutions are then further treated and processed
until they can be discharged as wastewater into publicly-owned treatment works
in compliance with applicable laws and regulations. Some wastewater is also
generated by the Company's Fluid Recovery Service.
 
  Automotive/Retail Repair Services. The primary component of the Company's
Automotive/ Retail Repair Services is its Parts Cleaner Service which enables
businesses (such as service stations, car and truck dealers, small engine
repair shops and fleet maintenance shops) to clean parts in a convenient, cost
effective, safe and environmentally sound manner. In this service, the
Company's service representative places parts cleaner equipment and solvent
with a customer, and, at regular service intervals, cleans and maintains the
equipment, delivers clean solvent for use in the degreasing process, and
removes the dirty solvent.
 
  Industrial Services. The Company markets both its Parts Cleaner Service and
its Fluid Recovery Service to industrial customers in the U.S. through its
Industrial Services specialists. The Company's Industrial Services furnish the
same high quality parts cleaner service that is provided to Automotive/Retail
Repair customers. The Company's Fluid Recovery Service consists of the
collection of a wide variety of waste solvents and other liquid wastes
generated by industrial customers in relatively small quantities, averaging a
few 55-gallon drums per pickup. Depending
 
                                       1
<PAGE>
 
upon the content, the material collected by the Company in its Fluid Recovery
Service is either processed into a waste-derived fuel for use in the cement
manufacturing industry, recycled into usable solvent or disposed of through
incineration.
 
  Automotive and Industrial Parts Cleaning Equipment Conversion. The Company
provides a choice of several models of parts cleaners to customers for their
use as part of the Parts Cleaner Service. The Company also provides service to
customers who own their own parts cleaner equipment. In total, at the end of
1994, the Company was providing services for approximately 481,000 parts
cleaners at customers in the United States, of which approximately 368,000 were
owned by the Company and approximately 113,000 were owned by customers.
 
  The Company's Model 16 and 30 parts cleaners are the most prevalent parts
cleaner models furnished by the Company. They consist of a red sink atop a 16-
gallon or 30-gallon drum of solvent, equipped with a submersible pump and a
spout through which the solvent flows.
 
  In 1993, the Company introduced a new parts cleaning machine that was
designed to replace most of its existing Model 16 and 30 parts cleaners. This
new parts cleaner was developed in response to customer desires to minimize the
amount of waste they generate and reduce their annual cost, and is the result
of extensive research and testing conducted by the Company. The new parts
cleaner utilizes a premium nonhazardous solvent and contains a patented
cyclonic separator which mechanically separates dirt particles from the solvent
during machine operation and traps them in a container for removal during
servicing. This system extends the solvent's useful life and reduces the number
of annual services required. With the new cyclonic parts cleaner service,
customers need service less frequently and generate less waste on an annual
basis, which reduces the cost of the parts cleaner service to Safety-Kleen and
also provides customers with the potential to reduce their cost.
 
  The Company began converting the Model 16 and 30 parts cleaners being used by
its domestic Automotive/Retail Repair and Industrial Services customers to the
new cyclonic technology in late 1993. At December 31, 1994, the Company had
placed approximately 103,000 cyclonic parts cleaners at customer locations, and
there were approximately 155,000 Model 16 and 30 parts cleaning machines
remaining in service in the United States. The Company expects to convert a
large portion of the remaining Model 16 and 30 parts cleaning machines to the
cyclonic parts cleaner in 1995 and 1996.
 
  In conjunction with the Company's decision to convert its parts cleaning
equipment, the Company adopted a comprehensive restructuring plan during the
fourth interim period of 1993. For a discussion of this restructuring plan,
refer to "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Restructuring and Special Charges" appearing on page 24
of the Annual Report, which is incorporated herein by reference.
 
  In 1994, the Company developed and test marketed a proprietary filtration
device which can be added to larger Safety-Kleen machines and a substantial
portion of customer-owned parts cleaners. The Company believes this filtration
device should provide these customers with the opportunity to receive waste
minimization and cost reduction benefits similar to the cyclonic parts cleaner
service.
 
  Paint Refinishing Services. The Company's Paint Refinishing Services are
supplied to new and used car dealers, auto body repair and paint shops and
fiberglass product manufacturers. The Company provides a machine specially
designed to clean paint spray guns. Company representatives place a machine and
solvent with each customer, maintain the machine and regularly remove the
contaminated solvent and replace it with clean solvent. Waste paint is also
collected from these customers. The Company either recycles the contaminated
solvent and waste paint into clean solvent for reuse or blends it into fuel for
cement kilns. The Company representatives also provide clean buffing pads and
remove dirty pads during regularly scheduled service calls. The dirty pads are
washed, dried, inspected and returned to the Company's distribution system.
 
                                       2
<PAGE>
 
  Dry Cleaner Services. The Company collects and recycles contaminated dry
cleaner wastes consisting primarily of used filter cartridges and sludge
containing perchloroethylene and mineral spirits.
 
  Imaging Services. Through this service, the Company provides spent
photochemical recovery and recycling services to health care, printing,
photoprocessing and other businesses. The Company's entry into this new
business was accelerated with the acquisition of Boston Recovery Company in
October 1994 and Drew Resource Corporation in February 1995.
 
ENVIROSYSTEMS SERVICE
 
  The Company's Envirosystems Service consists of the collection of waste
solvent and other waste fluids from customers which generate larger quantities
of such waste fluids. The fluids are typically shipped directly from the
customer to one of the Company's recycle centers or fuel blending facilities.
Depending on the content, material collected by the Envirosystems Service is
recycled for reuse, processed into fuels for use in the cement manufacturing
industry or disposed of through incineration.
 
OIL RECOVERY SERVICES
 
  The Company collects used lubricating oils from automobile and truck dealers,
automotive garages, oil change outlets, service stations, industrial plants and
other businesses and either re-refines the oil into reusable lubricating oil or
processes it into fuel for use in industrial furnaces. The Company derives
revenues both from fees it charges customers to haul away used oil and from the
sale of products it produces by processing the used oil. The Company's
extensive branch network enables it to collect waste oil in sufficient volume
to support oil re-refining operations, which produce lubricating oil that can
be sold at significantly higher prices than industrial fuels. The Company
operates oil re-refining plants in Ontario, Canada and East Chicago, Indiana.
The plants in Ontario and East Chicago have annual capacities of 34 and 85
million gallons of used oil per year, respectively. Waste oil collected in
excess of the capacity of the Company's re-refining facilities is either
processed into industrial fuels or, to a small extent, sold unprocessed for
direct use as a fuel in certain industrial applications for which such oil is
suitable.
 
EUROPE
 
  The Company primarily provides its Automotive/Retail Repair and Paint
Refinishing Services in Europe. The Company's German operations also offer the
Envirosystems Service. The Company introduced its Fluid Recovery Services in
the United Kingdom during 1994.
 
PRIMARY RAW MATERIALS
 
  The primary hydrocarbon material used in the Company's Parts Cleaner Service
is a paraffinic hydro-treated petroleum fraction product that is purchased from
petroleum refiners and suppliers through short-term purchase orders. It is not
possible for the Company to accurately estimate the effect of possible future
petroleum product shortages on the Company's operations or those of its
customers. At the present time, the Company expects to be able to purchase
required quantities of such solvent at acceptable prices. For a discussion of
the effect of petroleum product price changes, refer to "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Effects of Petroleum Price Changes" appearing on page 21 of the Annual Report,
which is incorporated herein by reference.
 
  The Company purchases a wide variety of other products and raw materials and
has not experienced any major shortages in the past. The Company believes that
sufficient alternative sources are available should it become necessary to
replace its current sources of supply for these products and materials.

COMPETITIVE CONDITIONS
 
  The Company is the market leader in the United States in its Parts Cleaner,
Paint Refinishing, Dry Cleaner and Oil Recovery services. In these services,
the Company generally competes with local or smaller regional companies. In its
Fluid Recovery Service, the Company generally competes with many firms engaged
in the transportation, brokerage and/or disposal of hazardous wastes through
recycling, fuels programs or incineration. In its Envirosystems Services, the
Company competes with many recyclers of spent solvents, as well as many firms
engaged in hazardous waste disposal through fuels programs or incineration.
 
  The principal methods of competition for all of the Company's services are
price, quality, reliability of service rendered and technical proficiency in
handling hazardous wastes properly. Knowledgeable customers are interested in
the reputation and financial strength of the companies they use for management
of their hazardous wastes, since the original generators of hazardous waste
remain liable under federal and state environmental laws for improper disposal
of such wastes, even if they employ companies which have proper permits and
licenses. The Company believes that its technical proficiency, reputation and
financial strength are important considerations to its customers in selecting
and continuing to utilize the Company's services.
 
PATENTS
 
  The Company owns various patents covering certain of its cleaning units and
certain related accessories. The Company has an exclusive license to use a
patented cyclonic separator in parts cleaner applications. In the Company's
opinion, however, the continued conduct of its business operations does not
depend upon the existence of these patents.
 
EMPLOYEES
 
  At December 31, 1994, the Company had approximately 6,600 employees.
 
REGULATION
 
  Overview. Domestic and foreign governmental regulations applicable to the
Company's business govern, among other things: the handling of a number of
substances collected by the Company which are classified as hazardous or solid
wastes under these regulations; the operation of the facilities at which the
Company stores or processes the substances it collects; and the ultimate
disposal of waste the Company removes from the substances it collects. An
increase in governmental requirements for the treatment of any particular
material generally increases the value of the Company's services to its
customers, but may also increase the Company's costs.
 
  Various permits are generally required by federal and state environmental
agencies for the Company's branch, accumulation center, solvent recycling, fuel
blending and oil processing facilities. Most of these permits must be renewed
periodically and the governmental authorities involved have the power, under
various circumstances, to revoke, modify or deny issuance or renewal of these
permits. Zoning, land use and siting restrictions also apply to these
facilities. Regulations also govern matters such as the disposal of residual
chemical wastes, operating procedures, stormwater and wastewater discharges,
fire protection, worker and community right-to-know and emergency response
plans. Air and water pollution regulations govern certain operations at the
Company's facilities. Safety standards under the Occupational Safety and Health
Act in the United States and similar foreign laws are also applicable.
Governmental regulations also apply to the operation of vehicles used by the
Company to transport the substances it collects and distributes, including
licensing requirements for the vehicles and the drivers, vehicle safety
requirements, vehicle weight limitations, shipment manifesting and vehicle
placarding requirements. Governmental authorities have the power to enforce
compliance and violators are subject to civil and criminal penalties. Private
individuals may also have the right to sue to enforce compliance with certain
of the governmental requirements.
 
                                       4
<PAGE>
 
  Regulations similar to those in the United States apply to the Company's
Canadian operations. In general, environmental requirements are not as strict
in countries in which the Company operates outside North America, but there is
a general trend in Europe and other countries to strengthen environmental
requirements.
 
  The Company has an internal staff of lawyers, engineers, geologists,
hydrogeologists, chemists and safety professionals whose responsibility is to
continuously improve the procedures and practices to be followed by the Company
to comply with various federal, state and local laws and regulations involving
the protection of the environment and worker health and safety and to monitor
compliance.
 
  Hazardous and Solid Waste Requirements. Safety-Kleen's services involve the
collection, transportation, storage, processing, recycling and disposal of
automotive and industrial hazardous and nonhazardous fluids. Substantially all
of these materials are regulated in the United States as "solid wastes" under
the Resource Conservation and Recovery Act of 1976 ("RCRA"). In addition to
being regulated as solid wastes, many of these materials are further regulated
as "hazardous wastes". Accordingly, the Company is subject to federal and state
regulations governing hazardous and solid wastes. RCRA established a national
program which classified various substances as "hazardous wastes", established
requirements for storage, treatment and disposal of hazardous wastes, and
imposed requirements for facilities used to store, treat or dispose of such
wastes. RCRA was amended in 1984 by the Hazardous and Solid Waste Amendments
("HSWA") which expanded the scope of RCRA to include businesses which generate
smaller quantities of waste materials (so-called "small quantity generators"),
expanded the substances classified as hazardous wastes by RCRA and prohibited
direct disposal of those wastes in landfills (thereby, in effect, requiring
that the wastes be recycled, treated, or destroyed).
 
  The Company's customers are increasingly attempting to avoid being subject to
hazardous waste regulations by replacing hazardous materials used in their
businesses with nonhazardous materials or otherwise reducing the amount of
hazardous waste they generate. Accordingly, the Company is collecting more
substances that are not regulated as hazardous wastes but may be regulated as
solid wastes.
 
  Hazardous and solid waste regulations impose requirements which must be met
by facilities used to store, treat and dispose of these wastes. Operators of
hazardous waste storage, disposal and treatment facilities, such as Safety-
Kleen, must obtain a RCRA permit from federal or authorized state governmental
authorities to operate those facilities. States may also require a solid waste
permit. The Company has over 100 RCRA-permitted facilities and is pursuing RCRA
permits at a small number of its other facilities. The Company does not intend
to pursue RCRA permits for its remaining facilities because it will be limiting
activities at these facilities to transfer operations.
 
  In September, 1992, the United States Environmental Protection Agency ("EPA")
finalized regulations that govern the management of used oils. Although used
oil is not classified as a hazardous waste under federal law, certain states do
regulate used oil as hazardous. The Company builds and operates its used oil
facilities to standards similar to those required for hazardous waste
facilities, and believes that its oil management standards are more protective
of human health and the environment than current federal standards.
 
  Fluids collected by the Company's Envirosystems and Fluid Recovery Services
are primarily recycled for reuse or processed into fuel to be burned in kilns
used in the production of cement. Fluids that are processed into waste-derived
fuel are supplied to cement kilns. The majority of such waste-derived fuel is
supplied to cement kilns with which the Company has exclusive supply contracts
with respect to such fuel. In August, 1991, cement kilns became subject to
regulations which govern the burning of hazardous wastes in boilers and
industrial furnaces ("BIF regulations"). Facilities covered
 
                                       5
<PAGE>
 
by the BIF regulations were required to submit certifications of compliance by
August 1, 1992 or to obtain approvals from the relevant governmental authority
to extend the deadline for submission of certification. Every BIF facility that
elects to continue to burn hazardous waste will also be required to obtain a
RCRA operating permit. All of the kilns with which the Company has exclusive
supply contracts have either obtained their compliance certifications or are in
the process of doing so pursuant to an authorized extension. These kilns are
also in the process of obtaining their RCRA operating permits. None of the
kilns utilized by the Company for disposition of the waste it collects are
owned by the Company. The Company is taking an increasingly more active role in
assisting the kilns with which it has exclusive contracts in complying with
such regulations.
 
  The United States EPA is developing regulations which will establish
management standards for cement kiln dust ("CKD"). The Company and the kilns to
which it sends waste-derived fuel have developed programs for analyzing and
characterizing CKD in anticipation of these new management standards; however,
at this time it is not clear what impact these CKD regulations will have on the
Company.
 
  Clean Air Act. The Clean Air Act was passed by Congress to control the
emissions of pollutants to the air, and requires permits to be obtained for
certain sources. In 1990, Congress amended the Clean Air Act to require further
reductions of air pollutants with specific targets for nonattainment areas in
order to meet certain ambient air quality standards. These amendments also
require the EPA to promulgate regulations which: (i) control emissions of 189
toxic air pollutants; (ii) create uniform operating permits for major
industrial facilities similar to RCRA operating permits; (iii) mandate the
phase-out of ozone depleting chemicals; and (iv) provide for enhanced
enforcement.
 
  The Clean Air Act requires states to promulgate regulations which will result
in the reduction of volatile organic compound (VOC) emissions by 15% by 1996 in
order to meet certain ozone attainment standards under the act. This will
require emission reductions at the Company's recycle centers and branches and
could affect its solvents used in nonattainment areas. In addition, the United
States EPA is developing Maximum Achievable Control Technology ("MACT")
standards under the Clean Air Act which will impose restrictions on the
emission of certain toxic air pollutants. These standards could impact certain
of the Company's facilities and the cement kilns to which the Company sends its
waste-derived fuels.
 
  In order to comply with these regulations, the Company has instituted a
program to augment the air emission control equipment at its affected
facilities and to obtain operating permits, where required. The Company is also
working with the United States EPA and appropriate state and local agencies
regarding the regulation of its parts cleaner and paint spray gun cleaner
operations.
 
  The Clean Air Act will also require a certain percentage of the new vehicles
purchased by the Company after 1995 in nonattainment areas to be clean-fuel-
burning vehicles. Furthermore, the Company will be required to implement
Employee Commute Reduction Plans by providing car and van pooling or
implementing other options in nonattainment areas where the Company has more
than 100 employees.
 
  CERCLA and Related Requirements. The Comprehensive Environmental Response,
Compensation and Liability Act of 1980 ("CERCLA") was originally enacted in
December, 1980, and amended in 1986 by the Superfund Amendments and
Reauthorization Act ("SARA"). Federal funding for the CERCLA program was
reauthorized in 1990. CERCLA creates a fund of monies ("Superfund") which can
be used by the EPA and state governments to clean up hazardous waste sites
pending recovery of those costs from defined categories of "potentially
responsible parties" ("PRPs"). Most EPA cleanup efforts are at sites listed or
proposed for listing on the National
 
                                       6
<PAGE>
 
Priorities List ("NPL"). Various states have also enacted statutes which
contain provisions substantially similar to CERCLA.
 
  Generators and transporters of hazardous substances, as well as past and
present owners and operators of hazardous release sites, are made strictly,
jointly and severally liable for the clean-up costs resulting from releases and
threatened releases of CERCLA-regulated "hazardous substances." Under CERCLA,
these responsible parties can be ordered to perform a clean-up, can be sued for
costs associated with private party or public agency clean-up, or can
voluntarily settle with the government concerning their liability for clean-up
costs.
 
  A large portion of the materials collected by the Company are recycled or
converted into materials, such as industrial fuels, which may be used for
another purpose. The amount of material that the Company deposits at waste
sites is accordingly small in relation to the volume of materials collected by
the Company, and the Company is actively engaged in a waste minimization
program to reduce this small amount even further. The Company also sends some
of the materials it collects to selected third party facilities for further
treatment, processing and/or disposal. The Company audits each of these
facilities prior to shipping any materials to attempt to minimize its potential
superfund liability at these sites.
 
  Most of the Company's CERCLA responsibilities stem from certain historic
disposal practices in the 1970's. These practices were stopped in the mid-to-
late 1970's with the development of expanded recycling technology. The Company
has been a relatively small contributor in most waste disposal sites utilized
by the Company.
 
  Proceedings are currently pending involving several sites with respect to
which the Company has been notified by the EPA or the appropriate state agency
that the Company may be a PRP. The Company is participating in settlement
discussions with the parties and the government at these sites. The Company's
volumetric share of the total waste at a majority of these sites is among the
smallest of the PRPs and the Company has a larger volumetric share at a
minority of these sites. The EPA has requested information from the Company to
ascertain if it may be a PRP at several other sites, but the Company has no
record of having dealings with any of these other sites. The Company has
already settled its liability at eighteen superfund sites.
 
  Costs of Increasing Regulations and Higher Fees and Taxes. State and local
authorities are increasingly adopting legislation and regulations which impose
stricter operating and performance standards and increased taxes, assessments
and fees upon the generators, transporters and handlers of hazardous and
nonhazardous waste. Although historically the Company has been able to pass
most of the costs associated with such legislation and regulations on to its
customers through price increases, there can be no assurance it will be able to
continue to do so in the future.
 
  Capital and Certain Other Expenditures Related to the Environment. A portion
of the Company's capital expenditures are related to compliance with
environmental laws and regulations. The Company estimates capital spending of
approximately $7 million for the year 1995 and $14 million in the aggregate,
for the years 1996 through 1999 in order to comply with RCRA, the Clean Air Act
and other environmental laws and regulations currently in effect in conjunction
with the Company's existing business.
 
  In addition to these capital expenditures, the Company may incur costs in
connection with closure activities at certain of its sites. When the Company
discontinues using or, in certain cases, changes the use of a hazardous waste
management unit, formal closure procedures must be followed. These closure
procedures must be approved by federal or state environmental authorities. In
some cases, costs are incurred to complete remedial cleanup work at the site.
In addition, at certain of the Company's other operating sites, remedial
cleanup work is required as part of the RCRA Corrective
 
                                       7

Action Program or other state and federal programs. As shown on the Company's
Consolidated Balance Sheet and more fully described in note 9 to the
Consolidated Financial Statements at pages 28 and 38, respectively, of the
Annual Report, the Company has accrued liabilities of approximately $50 million
as of December 31, 1994 for facility closures, remedial cleanup work, superfund
site liability and certain other environmental expenses related to its
operating and previously closed sites.
 
  Enforcement Actions. The Company's goal is to fully comply with all
environmental regulations and other governmental requirements. The Company has
instituted several programs to enhance compliance, including suspending site
operations if appropriate corrective actions are not taken to remedy potential
defects. The Company conducts regular audits of its facilities to assess
compliance with federal and state environmental and safety laws and
regulations. Any potential deficiencies are identified and a corrective action
plan is prepared and implemented to eliminate the potential defect. In 1994 the
Company conducted over 460 such audits. The Company regularly conducts
corporate training courses and seminars focused on environmental control and
safety regulations, in addition to on-going weekly field training for its site
employees.
 
  In spite of the Company's goal to fully comply with all environmental
regulations, given the Company's extensive operations, the technical aspects of
the regulations and the varying interpretations of the requirements from
jurisdiction to jurisdiction, the Company may incur governmental fines and
penalties from time to time. In the majority of situations where proceedings
are commenced by governmental authorities, the matters involved relate to
alleged violations of permits or orders under which the Company operates, or
laws and regulations to which its operations are subject, and are the result of
varying interpretations of the applicable requirements. Generally, these
proceedings result from routine inspections conducted by federal and state
regulatory agencies. In 1991 and 1992, throughout its United States facilities,
201 and 142 regulatory proceedings, respectively, were brought by state or
federal authorities against the Company. In 1993, this number was reduced to
136. This number was reduced again in 1994 to 130. Administrative actions are
counted in the year notice of the violation is received by the Company,
regardless of when the inspection giving rise to the action was conducted. Some
of the proceedings brought in 1994 resulted from inspections performed in
previous years. Of these administrative actions in 1994, approximately 16% of
the alleged deficiencies related to incomplete or incorrect manifests and other
shipping documents. Alleged defects in site operating records, training record
keeping and other paperwork accounted for an additional 44% of these
allegations. The Company processed over one million manifests and completed
several million individual drum labels in 1994. Throughout its facility
network, the Company maintains over 200 sets of operating records and logs in
which millions of individual entries are made annually. A clerical error on a
manifest, drum label or site paperwork can result in a violation notice.
 
  From time to time, the Company becomes subject to proceedings in which
governmental authorities may seek fines and/or penalties from the Company which
exceed $100,000 in each case. Six such proceedings were pending against the
Company at December 31, 1994. In these cases, the governmental authorities
involved may allege, among other things, that at certain of the Company's
facilities, the Company is responsible for releases or threatened releases of
hazardous substances, that the Company engaged in soil excavation or clean-up
activities without obtaining requisite advance approvals and/or that the
Company committed certain manifesting, storage and/or waste handling
violations.
 
  Five such cases were settled during 1994. Two of these five cases were
settled during the first three quarters of 1994 and were previously disclosed
in the Company's quarterly reports on Form 10-Q. The three remaining cases were
settled during the fourth quarter of 1994. In these three cases, the Company
and the State of Ohio entered into a settlement agreement involving alleged
hazardous waste violations at the Company's eight Ohio facilities which
resolved differences in regulatory
 
                                       8

interpretation and technical issues with the Ohio EPA and resolved alleged
violations dating back to 1986. Pursuant to the agreement, Safety-Kleen paid a
penalty of $825,000, agreed to expend $165,000 for household hazardous waste
collections in Ohio over the next three years and reimbursed the Ohio Attorney
General's Office $10,000 for processing costs.
 
  The Company's practice is to attempt to negotiate resolution of claims
against the Company and its facilities. The Company has to date been able to
resolve cases on generally satisfactory terms. The Company is, however,
prepared to contest claims or remedies which the Company believes to be
inappropriate unless and until satisfactory settlement terms can be agreed
upon. The Company paid approximately $4 million in 1994 for environmental
fines, penalties and forfeitures.
 
  Potential Environmental Liabilities. Based on its past experience and its
knowledge of pending cases, the Company believes it is unlikely that the
Company's actual liability on cases now pending (including enforcement actions
of the type described above and CERCLA or state superfund cases) will be
materially adverse to the Company's financial condition. It should be noted,
however, that many environmental laws are written in a way in which the
Company's potential liability can be large, and it is always possible that the
Company's actual liability on any particular environmental claim will prove to
be larger than anticipated or accrued for by the Company. It is also possible
that expenses incurred in any particular reporting period for remediation costs
or for fines, penalties, or judgments could have a material impact on the
Company's results of operations for that period.
 
FINANCIAL INFORMATION RELATING TO FOREIGN AND DOMESTIC OPERATIONS AND INDUSTRY

with environmentally safe and convenient solutions for managing fluid waste and
other recoverable resources. For a discussion of financial information relating
to foreign and domestic operations and industry segments refer to Note 3 to the
Consolidated Financial Statements appearing on pages 31 and 32 of the Annual

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and
Shareholders of Safety-Kleen Corp.:
 
  We have audited in accordance with generally accepted auditing standards, the
consolidated financial statements included in the Safety-Kleen Corp. annual
report to shareholders incorporated by reference into this Form 10-K, and have
issued our report thereon dated February 9, 1995. Our report on the
consolidated financial statements includes an explanatory paragraph with
respect to the changes in the methods of accounting for post-retirement
benefits other than pensions and accounting for income taxes, effective
December 29, 1991, as discussed in Notes 7 and 8 to the consolidated financial
statements. Our audits were made for the purpose of forming an opinion on the
basic financial statements taken as a whole. The Supplemental Schedule II is
the responsibility of the Company's management and is presented for purposes of
complying with the Securities and Exchange Commission's rules and is not part
of the basic financial statements. This schedule has been subjected to the
auditing procedures applied in the audits of the basic financial statements
and, in our opinion, fairly states in all material respects, the financial data
required to be set forth therein in relation to the basic financial statements
taken as a whole.

                                   ARTICLE I

                                    OFFICES

       The principal office of the Corporation in the State of Wisconsin shall
be located in the City of Milwaukee, County of Milwaukee.  The Corporation may
have such other offices, either within or without the State of Wisconsin, as the
Board of Directors may designate or as the business of the Corporation may
require from time to time.

       The registered office of the Corporation required by the Wisconsin
Business Corporation Law to be maintained in the State of Wisconsin may be, but
need not be, identical with the principal office in the State of Wisconsin, and
the address of the registered office may be changed from time to time by the
Board of Directors.


                                   ARTICLE II

                                  SHAREHOLDERS

       Section 1 - Annual Meeting.

       The annual meeting of the shareholders shall be held on a weekday on such
date and at such time as the Board of Directors may determine, for the purpose
of electing directors and for the transaction of such business as may properly
come before the meeting.  If the election of directors shall not be held on the
day designated herein for any annual meeting, or at any adjournment thereof, the
Board of Directors shall cause the election to be held at a special meeting of
the shareholders as soon thereafter as conveniently is possible.

       Section 2 - Special Meeting (of Shareholders).

       Special meetings of the shareholders may be called by the Chairman of the
Board, or the Board of Directors, and, subject to the provisions of the second
paragraph of Article II, Section 4 below, shall be called by the President at
the request of the holders of at least one-tenth of all votes entitled to be
cast on any issue proposed at the meeting.

       Section 3 - Place of Meeting.

       The Board of Directors may designate any place, either within or without
the State of Wisconsin, as the place of meeting for any annual meeting or for
any special meeting called by the Board of Directors.  If no designation is
made, or if a special meeting be otherwise called, the place of meeting shall be
the principal office of the Corporation, but any meeting may be adjourned to
reconvene at any place designated by the Chairman of the meeting.

       Section 4 - Notice of Meeting.

       Written notice stating the place, day and hour of the meeting and the
purpose or purposes for which the meeting is called, shall be delivered not less
than 10 nor more than 60 days before the day of the meeting, either personally
or by mail, by or at the direction of the  President, the Secretary, or the
Officer or persons calling the meeting, to each shareholder of record entitled
to vote at such meeting.  If mailed, such notice shall be deemed to be delivered
when deposited in the United States mail, addressed to the shareholder at his
address as it appears on the stock record books of the Corporation, with postage
thereon prepaid.

       For a meeting to be properly called by the President at the request of
the holders of at least one-tenth of all votes entitled to be cast on any issue
proposed at the meeting, the shareholders requesting the meeting must give
notice of such request in writing containing the applicable information,
required in Sections 12 and 13 hereof, and such notice must be signed and dated
by each such requesting shareholder and delivered to the Secretary at the
principal executive offices of the Corporation.  The Board of Directors shall
promptly, but in all events within 10 business days after the date on which such
notice is received, adopt a resolution (i) setting the date for such meeting,
which date shall be not more than 180 and not less than 10 days from the date on
which such resolution is adopted and (ii) fixing the record date for such
meeting in accordance with Section 5 hereof.  Shareholders requesting such a
meeting shall pay for all costs incurred in connection with calling and holding
such meeting, including all reasonable costs incurred by the Corporation with
respect thereto.

       Any previously scheduled meeting of shareholders may be postponed by
resolution of the Board of Directors upon public notice given prior to the date
previously scheduled for such meeting provided, however, that any special
meeting called at the request of holders of at least one tenth of all votes
entitled to be cast on any issue proposed at the meeting may not be postponed to
a date more than 180 days following the date on which the Board of Directors
adopted the resolution which fixed the original date of such meeting.

       Only such business shall be conducted at a special meeting of
shareholders as shall have been set forth as the purpose or purposes of such
special meeting in the Corporation's notice of such special meeting.

       Section 5 - Fixing of Record Date.

       For the purpose of determining shareholders entitled to notice of or to
vote at any meeting of shareholders or any adjournment thereof, or shareholders
entitled to receive payment of any dividend, or in order to make a determination
of shareholders for any other proper purpose, the Board of Directors of the
Corporation may fix in advance a date as the record date for any such
determination of shareholders, such date in any case to be not more than 70
days, and, in case of a meeting of shareholders, not less than 10 days, prior to
the date on which the particular action, requiring such determination of
shareholders, is to be taken.  If no record date is fixed for the determination
of shareholders entitled to notice of or to vote at a meeting of shareholders or

shareholders entitled to receive payment of a dividend, the date on which notice
of the meeting is mailed or the date on which the resolution of the Board of
Directors declaring such dividend is adopted, as the case may be, shall be the
record date for such determination of shareholders.  When a determination of
shareholders entitled to vote at any meeting of shareholders has been made, as
provided in this section, such determination shall be applied to any adjournment
thereof, provided, however, that the Board of Directors will fix a new record
date if such meeting is adjourned to a date more than 120 days after the date
fixed for the original meeting.

       Section 6 - Voting Lists.

       The officer or agent having charge of the stock transfer books for shares
of the Corporation shall make, within two business days after notice of the
meeting is given, a complete list of the shareholders entitled to vote at such
meeting, or any adjournment thereof, arranged in alphabetical order, with the
address of and the number of shares held by each, which list, until the time of
such meeting, shall be kept on file at the registered office of the Corporation
and shall be subject to inspection by any shareholder at any time during usual
business hours.  Such list shall also be produced and kept open at the time and
place of the meeting and shall be subject to the inspection of any shareholder
during the whole time of the meeting.  The original stock transfer books shall
be prima facie evidence as to who are the shareholders entitled to examine such
list or transfer books or to vote at any meeting of shareholders.  Failure to
comply with the requirements of this section shall not affect the validity of
any action taken at such meeting.

       Section 7 - Quorum.

       A majority of the outstanding shares of the Corporation entitled to vote,
represented in person or by proxy, shall constitute a quorum at a meeting of
shareholders.  Whether or not such quorum is present or represented at any
meeting of shareholders, the Chairman of the meeting may adjourn the meeting
from time to time without further notice other than announcement at the meeting;
provided, however, that when a meeting is so adjourned to another time or place,
notice of the adjourned meeting need not be given only if the date, time and
place thereof are announced at the original meeting, if the adjournment is for
not more than 120 days and if no new record date is fixed for the adjourned
meeting.  At such adjourned meeting at which a quorum shall be present or
represented, only such business may be transacted which might have been
transacted at the meeting as originally notified.  The Chairman of the Board of
Directors shall act as the Chairman of all meetings of shareholders and, in the
absence of the Chairman of the Board of Directors, the President shall preside.
In the absence of the President, the Board of Directors shall designate any
other Director, Officer or employee of the Corporation to preside at such
meeting.

       Section 8 - Proxies.

       At all meetings of shareholders, a shareholder entitled to vote may vote
by proxy appointed in writing by the shareholder or by his duly authorized
attorney in fact.  Such proxy shall be filed with the Secretary of the
Corporation before or at the time of the meeting.  No proxy shall be valid after
eleven months from the date of its execution, unless otherwise provided in the
proxy.

       Section 9 - Voting of Shares.

       Subject to the Articles of Incorporation, each outstanding share entitled
to vote shall be entitled to one vote upon each matter submitted to a vote at a
meeting of shareholders.  Unless otherwise required by the Articles of
Incorporation or applicable law, Directors shall be elected by a plurality of
the votes cast by the shares entitled to vote in the election at which a quorum
is present.  Unless otherwise required by the Articles of Incorporation or
applicable law, the affirmative vote of the holders of a majority of the shares
present or represented at a meeting of shareholders at which a quorum is present
or represented shall be required to decide all matters brought before such
meeting other than the election of Directors.

       Section 10 - Voting Company's Shares.

       Shares of the Corporation belonging to it shall not be voted directly or
indirectly at any meeting and shall not be counted in determining the total
number of outstanding shares at any given time, but shares held by this
Corporation in a fiduciary capacity may be voted and shall be counted in
determining the total number of outstanding shares at any given time.

       Section 11 - Shares in Other Corporation's Name.

       Shares standing in the name of another corporation may be voted either in
person or by proxy,  by a duly appointed officer of such corporation who has
been authorized to cast such votes or execute such proxies.  A proxy executed by
any principal officer of such other corporation shall be conclusive evidence of
the signer's authority to act, in the absence of express notice to this
Corporation, given in writing to the Secretary of this Corporation, of the
designation of some other person by the board of directors or the by-laws of
such corporation.

       Section 12 - Notice of Shareholder Business.

       At all meetings of the shareholders, only such business shall be
conducted as shall have been brought before the meeting (a) by or at the
direction of the Board of Directors or (b) by any shareholder of the Corporation
who was a shareholder of record at the time of the giving of notice as provided
in this Section 12, who is entitled to vote at the meeting and who complies with
the notice procedures set forth in this Section 12.  In order for business to be
properly brought before the meeting by a shareholder, such business, as
determined by the Chairman of the meeting, must be a proper subject under
Wisconsin law.  For business to be properly brought before an annual meeting by
a shareholder, the shareholder must have given timely notice thereof in writing
to the Secretary of the Corporation.  To be timely, a shareholder's notice must
be delivered to or mailed and received at the principal executive offices of the
Corporation, not less than 60 days nor more than 90 days prior to the meeting;

       The directors shall be divided into three classes as nearly equal in
number as possible.  At the 1986 annual meeting of shareholders the directors
were so divided, with the term of office of the first class to expire at the
1987 annual meeting of shareholders, the term of office of the second class to
expire at the 1988 annual meeting of shareholders and the third class to expire
at the 1989 annual meeting of shareholders.  At each annual meeting of
shareholders, directors elected to succeed those whose terms expire shall be
elected for a term of office expiring at the third succeeding annual meeting of
shareholders after their election and until their successors shall be elected
and shall qualify.  Directors need not be residents of the State of Wisconsin or
shareholders of the Corporation.

       Section 3 - Regular Meetings.

       A regular meeting of the Board of Directors shall be held without other
notice than this by-law immediately after, and at the same place as, the annual
meeting of shareholders, and each adjourned session thereof.  The Board of
Directors may provide by resolution, the time and place, either within or
without the State of Wisconsin, for the holding of additional regular meetings
without other notice than such resolution.

       Section 4 - Special Meetings.

       Special meetings of the Board of Directors may be called by or at the

for holding any special meeting of the Board of Directors called by them.

       Section 5 - Notice.

       Notice of any special meeting shall be given at least 48 hours previously
thereto by written notice delivered personally or mailed to each director at his
business address, or by telegram.  If mailed, such notice shall be deemed to be
delivered when deposited in the United States mail so addressed, with postage
thereon prepaid.  If Notice be given by telegram, such notice shall be deemed to
be delivered when the telegram is delivered to the telegraph company.  Whenever
any notice whatever is required to be given to any director of the Corporation
under the provisions of these by-laws or under the provisions of the articles of
incorporation or under the provisions of any statute, a waiver thereof in
writing, signed at any time, whether before or after the time of meeting, by the
director entitled to such notice, shall be deemed equivalent to the giving of
such notice.  The attendance of a director at a meeting shall constitute a
waiver of notice of such meeting, except where a director attends a meeting and
objects thereat to the transaction of any business because the meeting is not
lawfully called or convened.  Neither the business to be transacted at, nor the
purpose of, any regular or special meeting of the Board of Directors need be
specified in the notice or waiver of notice of such meeting.

shall not be necessary to make it effective.

       Section 8 - Newly-Created Directorships and Vacancies.

       Newly-created directorships resulting from any increase in the authorized
number of directors or any vacancies in the Board of Directors resulting from

of the directors or members of such committee, as the case may be, entitled to
vote with respect to the subject matter thereof.

     into the definitions of certain capitalized terms used herein, shall mean
     this Corporation.

(f)  "Director or Officer" shall have the meaning set forth in the Statute;
     provided, that, for purposes of this Article, it shall be conclusively
     presumed that any Director or Officer serving as a director, officer,
     partner, trustee, member of any governing or decision-making committee,
     employee or agent of an Affiliate shall be so serving at the request of the
     Corporation.

(g)  "Disinterested Committee" shall mean a committee duly appointed by the

     Parties to the subject Proceeding or any related Proceeding.

     Directors who are not at the time Parties to the subject Proceeding or any
     related Proceeding.

(i)  "Proceeding" shall have the meaning set forth in the Statute and, for
     purposes of this Article, "Proceeding" shall also include (i) any appeal
     therefrom; (ii) all Proceedings brought under (in whole or in part) the
     Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
     amended, their respective state counterparts, and/or any rule or regulation

       Each person who was or is made a Party or is threatened to be made a

Corporation or a director or officer of an Affiliate (who is not otherwise
serving as a Director or Officer) shall be indemnified and held harmless by the
Corporation to the fullest extent permitted under the Statute, as the same now
exists or may hereafter be amended (but, in the case of any such amendment, only

suffered by such person in connection therewith; provided, that except with
respect to a Proceeding brought before an Authority or otherwise to enforce
rights hereunder, the Corporation shall indemnify any such person seeking
indemnity in connection with a Proceeding (or part thereof) initiated by such
person only if such Proceeding (or part thereof) was authorized by the Board.

       Section 3 - Expense.

       The Corporation shall pay or reimburse, within ten days after the receipt
of a written request therefore, the reasonable Expenses of any person referred
to in Section 2 of this Article as such Expenses are incurred; provided, such
person furnishes to the Corporation (i) an executed written certificate
affirming his or her good faith belief that he or she has not engaged in a
Breach of Duty, and (ii) an unsecured written undertaking ("Undertaking"),
executed personally or on his or her behalf, to repay any allowances made under
this Section 3 if it is ultimately determined by an Authority that such person
is not entitled to be indemnified by the Corporation for such Expenses;
provided, further, that in connection with a Proceeding (or part thereof)
initiated by any such person, except with respect to a Proceeding brought before
an Authority or otherwise to enforce rights hereunder, the Corporation shall pay
such Expenses as incurred only if such Proceeding (or part thereof) was
authorized by the Board.  The Undertaking shall also provide that the person to
whom an allowance was paid pursuant to this Section 3 shall not be obligated to
repay the Corporation during the pendency of any Proceeding before an Authority,
and that if the Authority shall ultimately determine that such person is not
entitled to indemnification for such Expenses, such person shall not be required
to pay interest on such allowance.  The Board shall not require, and shall
accept the Undertaking without any showing of the claimant's ability to repay
the allowance.

       Section 4 - Procedural Requirements.

(a) Each person who seeks indemnification under Section 2 of this Article shall
    make a written request therefore to the Corporation. The Board shall act on
    such request at its next meeting held no less than two days, but no more
    than sixty days, after the receipt of such request. Such action shall be
    taken by a Disinterested Quorum or, if a Disinterested Quorum cannot be
    obtained, by a Disinterested Committee, which shall determine whether the
    claimant's conduct constituted a Breach of Duty. If such determination is
    favorable to the claimant, the Corporation shall pay or reimburse such
    claimant for the entire amount of requested Liabilities incurred by such
    claimant in connection with the subject Proceeding (net of any Expenses
    previously advanced pursuant to Section 3). If such determination is not
    favorable to the claimant or if a Disinterested Committee cannot be
    obtained, the Board by resolution shall authorize an Authority, as provided
    in Section 5 of this Article, to determine whether the claimant's conduct
    constituted a Breach of Duty and, therefore, whether indemnification is
    required hereunder. The determination by an Authority that indemnification
    is required hereunder shall be binding upon the Corporation regardless of
    any prior determination that the claimant engaged in a Breach of Duty.

(b) If the Board does not authorize an Authority to determine the claimant's
    right to indemnification hereunder, and indemnification of the requested
    amount of Liabilities is paid by the Corporation, it shall be conclusively
    presumed that a Disinterested Quorum has determined that the claimant did 
    not engage in misconduct constituting a Breach of Duty.

       Section 5 - Determination of Indemnification.

(a) If the Board authorizes an Authority to determine a claimant's right to
    indemnification pursuant to Section 4 of this Article, then the claimant
    shall have the absolute discretionary authority to select one of the
    following as such Authority:

      (i) An independent legal counsel; provided, that such counsel shall be
          mutually selected by such claimant and by a majority vote of a
          Disinterested Quorum or, if a Disinterested Quorum cannot be obtained,
          then by a majority vote of a Disinterested Committee or, if a
          Disinterested Committee cannot be obtained, then by a majority vote of
          the Board;

     (ii) A panel of three arbitrators selected from the panels of arbitrators
          of the American Arbitration Association in Chicago, Illinois;
          provided, that (A) one arbitrator shall be selected by such claimant,
          the second arbitrator shall be selected by a majority vote of a
          Disinterested Quorum or, if a Disinterested Quorum cannot be obtained,
          then by a majority vote of a Disinterested Committee or, if a
          Disinterested Committee cannot be obtained, then by a majority vote of
          the Board, and the third arbitrator shall be selected by the two
          previously selected arbitrators; and (B) in all other respects such
          panel shall be governed by the American Arbitration Association's then
          existing Commercial Arbitration Rules; or

    (iii) A court pursuant to and in accordance with Section 180.051 of the
          Statute.

(b)  In any such determination by the selected Authority there shall exist a
     rebuttable presumption that the claimant's conduct did not constitute a
     Breach of Duty and that indemnification against the requested amount of
     Liabilities is required. The burden of rebutting such a presumption by
     clear and convincing evidence shall be on the Corporation or such other
     party asserting that such indemnification should not be allowed.

(c)  The Authority shall make its determination as soon as practicable (but in
     any event within sixty days of being selected) and shall submit a written
     opinion of its conclusion simultaneously to both the Corporation and the
     claimant.

(d)  If the Authority determines that indemnification is required hereunder, the
     Corporation shall pay the entire requested amount of Liabilities (net of
     any Expenses previously advanced pursuant to Section 3), including interest
     thereon at a reasonable rate, as determined by the Authority, within ten
     days of receipt of the Authority's opinion; provided, that, if it is
     determined by the Authority that a claimant is entitled to indemnification
     as to some claims, issues or matters, but not as to other claims, issues or
     matters involved in the subject Proceeding, the Corporation shall be
     required to pay (as set forth above) only the amount of such requested
     Liabilities as the Authority shall deem appropriate in light of all of the
     circumstances of such Proceeding.

(e)  All expenses incurred in the determination process under this Section 5 by
     either the Corporation or the claimant, including, without limitation, all
     Expenses of the selected Authority, shall be paid by the Corporation.

       Section 6 - Employees and Agents.

       The Board may, in its sole and absolute discretion as it deems
appropriate, pursuant to a majority vote thereof, indemnify against Liabilities
incurred by, and/or provide for the allowance of reasonable Expenses of, an
employee or agent of the Corporation who is not otherwise a Director or Officer.

       Section 7 - Insurance.

       The Corporation may purchase and maintain, at its expense, insurance on
behalf of a Director or Officer or any individual who is or was an employee or
agent of the Corporation against any Liability asserted against or incurred by
such individual in his or her capacity as such or arising from his or her status
as such, regardless of whether the Corporation is required or permitted to
indemnify or allow Expenses to such individual against any such Liability under
the Statute or this Article.

       Section 8 - Non-Exclusivity of Rights.

       The rights conferred on any person by this Article shall not be deemed
exclusive of any other rights to indemnification or advancement of Expenses
which such person may be entitled to under any written agreement, Board
resolution, vote of shareholders of the Corporation or otherwise, including,
without limitation, under the Statute.  Nothing contained in this Article shall
be deemed to limit the Corporation's obligations to indemnify any person under
the Statute.

       Section 9 - Contractual Nature.

       The provisions of this Article shall be applicable to all Proceedings
commenced after its adoption, whether such arise out of events, acts or
omissions which occurred prior or subsequent to such adoption, and shall
continue as to a person who has ceased to be a Director or Officer and shall
inure to the benefit of the heirs, executors and administrators of such person.
This Article shall be deemed to be a contract between the Corporation and each
person who, at any time that this Article is in effect, serves or agrees to
serve in any capacity which entitles him to indemnification hereunder and any
repeal or other modification of this Article or any repeal or modification of
the Statute or any other applicable law shall not limit any rights of
indemnification then existing or arising out of events, acts or omissions
occurring prior to such repeal or modification, including, without limitation,
the right to indemnification for Proceedings commenced after such repeal or
modification to enforce this Article with regard to acts, omissions or events
arising prior to such repeal or modification.

       Section 10 - Severability.

       If any provision of this Article shall be deemed invalid or inoperative,
or if a court of competent jurisdiction determines that any of the provisions of
this Article contravene public policy, this Article shall be construed so that
the remaining provisions shall not be affected, but shall remain in full force
and effect, and any such provisions which are invalid or inoperative or which
contravene public policy shall be deemed, without further action or deed by or
on behalf of the Corporation, to be modified, amended and/or limited, but only
to the extent necessary to render the same valid and enforceable.

       Section 11 - Continuation of Obligations; Amendment.

       The obligations of the Corporation to indemnify any person or to advance
Expenses thereto under this Article shall continue as to the successors and
assigns of the Corporation and such obligations may only be limited by the
affirmative vote of two-thirds of the shareholders of the Corporation so
entitled to vote; provided, that any such limitation shall only apply to alleged
acts of any person for which indemnification is sought hereunder which occur
after such limitation is adopted.

by the affirmative vote of a majority of the Board of Directors at any regular
meeting of the Board of Directors or at any special meeting of the Board of
Directors if notice of the proposed making, alteration, amendment or repeal to

               (i) the name of each Subsidiary (indicating whether such

     or otherwise disposed of in the ordinary course of business), except for
     such failures to have good title as are immaterial to such balance sheet

               (i) All tax returns required to be filed by or on behalf of each
          of the Company and each Subsidiary and any other Person with which the
          Company or any Subsidiary files or has filed a consolidated return in
          any jurisdiction have been filed on a timely basis, and all taxes,
          assessments, fees and other governmental charges upon each of the

     2.10 RESTRICTIONS ON COMPANY AND SUBSIDIARIES.

     Neither the Company nor any Subsidiary:

          (a) is a party to any contract or agreement, or subject to any charter
     or other corporate restriction that, in the aggregate for all such
     contracts, agreements and charter and corporate restrictions, is reasonably
     likely to have a Material Adverse Effect;

          (b) is a party to any contract or agreement that restricts the right
     or ability of such corporation to incur Debt, other than this Agreement and
     the agreements listed in PART 2.10 OF ANNEX 3, none of which restricts the
     issuance and sale of the Notes or the performance of the Company hereunder
     or under the Notes, and true, correct and complete copies of each of which
     have been provided to you; or

          (c) has agreed or consented to cause or permit in the future (upon the

     Neither the Company nor any Subsidiary is in violation of any law,
ordinance, governmental rule or regulation to which it is subject, except for
such violations that, in the aggregate, could not reasonably be expected to have

     2.12 PENSION PLANS.

          (A) DISCLOSURE.  PART 2.12(A) OF ANNEX 3 correctly identifies all
     ERISA Affiliates and all employee benefit plans with respect to which the
     Company or any "affiliate" (as such term is defined in section 407(d) of
     ERISA) is a "party-in-interest" (as such term is defined in section 3 of
     ERISA) or in respect of which the Notes would constitute an "employer
     security" (as such term is defined in section 407(d) of ERISA).

          (B) PROHIBITED TRANSACTIONS.  The execution and delivery of this
     Agreement and the issuance and sale of the Notes hereunder will not involve
     any transaction that is subject to the prohibitions of section 406 of ERISA
     or in connection with which a tax could be imposed pursuant to section
     4975(c)(1)(A)-(D) of the IRC.  The representation by the Company in the
     immediately preceding sentence is made in reliance upon the representations
     in Section 1.3(b) as to the source of funds used by you.

          (C) COMPLIANCE WITH ERISA.  The Company and the ERISA Affiliates and
     each Pension Plan are in compliance with ERISA, except for such failures to
     comply that in the aggregate for all such failures could not reasonably be
     expected to have a Material Adverse Effect.

          (D) PLAN FUNDING STATUS AND LIABILITIES.

               (I) FUNDING STATUS.  Except as set forth in PART 2.12(D) OF ANNEX
          3, the aggregate amount of the "benefit liabilities" (as such term is
          defined in section 4001 of ERISA) under each Pension Plan, determined
          as of the end of each such Pension Plan's most recently ended plan
          year on the basis of the actuarial

                                       7                 Note Purchase Agreement

<PAGE>
 
                                              2.  WARRANTIES AND REPRESENTATIONS

          assumptions specified for funding purposes in such Pension Plan's most
          recent actuarial valuation report, did not exceed the aggregate
          "current value" (as such term is defined in section 3 of ERISA) of the
          assets of such Pension Plan allocable to such benefit liabilities.

               (II) CLOSING DATE LIABILITIES.  All liabilities to all Pension
          Plans and Multiemployer Plans that are due and payable as of the
          Closing Date have been paid, except for liabilities that, in the
          aggregate for all such liabilities, could not reasonably be expected
          to have a Material Adverse Effect.  Neither the Company nor any ERISA
          Affiliate has incurred any liability pursuant to Title I or Title IV
          of ERISA or the penalty or excise tax or security provisions of the
          IRC relating to "employee benefit plans" (as defined in section 3 of
          ERISA), and no event, transaction, or condition has occurred or exists
          that could result in the imposition of any Lien on any of the
          Properties of the Company or any ERISA Affiliate, in either case
          pursuant to Title I or Title IV of ERISA or pursuant to such penalty
          or excise tax or security provisions of the IRC, except for such
          liabilities and Liens that, in the aggregate for all such liabilities
          and Liens, could not reasonably be expected to have a Material Adverse
          Effect.

               (III)  MULTIEMPLOYER WITHDRAWAL LIABILITIES.  Neither the Company
          nor any ERISA Affiliate has incurred or currently expects to incur any
          withdrawal liability under Title IV of ERISA with respect to any
          Multiemployer Plan.  There have been no "reportable events" (as such
          term is defined in section 4043 of ERISA) with respect to any
          Multiemployer Plan that could result in the termination of such
          Multiemployer Plan and give rise to a liability of the Company or any
          ERISA Affiliate in respect thereof.

               (IV) PBGC.  No circumstance exists that constitutes grounds under
          section 4042 of ERISA entitling the PBGC to institute proceedings to
          terminate, or appoint a trustee to administer, any Pension Plan or
          trust created thereunder, nor has the PBGC instituted any such
          proceeding.

          (E) FOREIGN PENSION PLAN.  All Foreign Pension Plans have been
     established, operated, administered and maintained in compliance with all
     laws, regulations and orders applicable thereto except for such failures,
     in the aggregate for all such failures, to comply that could not reasonably

     event it shall sell or transfer any Note without surrendering such Note to
     the Company as set forth in Section 5.2(a), it shall

               (i)  prior to the delivery of such Note make a notation thereon
          of all principal, if any, prepaid on such Note and shall also indicate
          thereon the date to which interest shall have been paid on such Note,
          and

               (ii) promptly notify or cause the transferee to notify the
          Company of the name and address of the transferee of any such Note so

institutional investor's nominee) and such loss, theft, destruction or
mutilation), and

          (a) in the case of loss, theft or destruction, of indemnity reasonably
     satisfactory to the Company (provided that if the holder of such Note is an
     institutional investor or a nominee of an institutional investor, such
     holder's own unsecured agreement of indemnity shall be deemed to be
     satisfactory), or

          (b) in the case of mutilation, upon surrender and cancellation
     thereof,

the Company at its own expense will execute and deliver, in lieu thereof, a
replacement Note, dated and bearing interest from the date to which interest

          (B)  INITIAL DESIGNATION.

               (I) SUBSIDIARIES IN EXISTENCE ON THE CLOSING DATE.  Each
          Subsidiary in existence on the Closing Date shall be deemed to have
          been designated as an Unrestricted Subsidiary unless the Company shall
          indicate in PART 2.3(A) OF ANNEX 3 that such Subsidiary is a
          Restricted Subsidiary.

               (II) SUBSIDIARIES ACQUIRED AFTER THE CLOSING DATE.  The Company
          may, within thirty (30) days after the acquisition or creation of any
          Subsidiary, designate such Subsidiary as an Unrestricted Subsidiary or
          a Restricted Subsidiary and may notify the holders of the Notes within
          such thirty (30) day period.  If such notice is sent to the holders of
          the Notes within thirty (30) days after the acquisition or creation of
          such Subsidiary, such designation shall be retroactive to the date of
          such acquisition or creation.  If the Company fails to so make such
          designation (and send such notice) within such thirty (30) day period,
          such Subsidiary shall be deemed to have been retroactively (to the
          date of creation or acquisition) designated as an Unrestricted
          Subsidiary.

          (C) DESIGNATION OF SUBSIDIARIES AFTER INITIAL DESIGNATION.  The
     Company may, at any time after the initial designation of a Subsidiary as
     an Unrestricted Subsidiary, designate such Subsidiary as a Restricted
     Subsidiary, by notice sent (and dated the date of such sending)
     simultaneously to each holder of Notes.  Such designation shall take effect
     upon the sending of such notice.  No designation will be permitted to be
     made and no notice will be permitted to be sent at any time when a Default
     or an Event of Default is outstanding, and all designations made and
     notices sent at any such time will be ineffective.  After the designation
     of a Subsidiary as a Restricted Subsidiary, no further designations of such
     Subsidiary will at any time be permitted or effective.

          (D) EFFECT OF DESIGNATIONS ON FINANCIAL CALCULATIONS.  Calculations of
     financial amounts or ratios required by this Agreement to be made as of any
     date prior to the effective date of any designation of a Subsidiary as a
     Restricted Subsidiary or an Unrestricted Subsidiary shall not be restated
     as a result of such designation.

fair and reasonable terms no less favorable to the Company or such Restricted
Subsidiary than would obtain in a comparable arm's-length transaction with a
Person not an Affiliate.

     officers, agents and employees (collectively the "INDEMNITEES") free and

     (including, without limitation, attorneys' fees and expenses incurred in

     otherwise located on any of the Properties of the Company or any of the
     Subsidiaries; provided, that such liability, loss, cost, damage or expense
     will not include any liability, loss, cost, damage or expense which results
     from any negligent act or omission of such Indemnitee.  The foregoing
     indemnification will survive repayment of the Notes.

otherwise cause or suffer to exist or become effective any restriction (other
than statutory, regulatory or common law restrictions) on the right or power of

          automatically become immediately due and payable together with
          interest accrued thereon and, to the extent permitted by law, the
          Make-Whole Amount at such time with respect to the principal amount of
          such Notes, without presentment, demand, protest or notice of any
          kind, all of which are hereby expressly waived, and,

               (ii) If any Event of Default other than those specified in
          Section 8.1(g), Section 8.1(h) and Section 8.1(i) shall exist, the
          holder or holders of at least twenty-five percent (25%) in principal
          amount of the Notes then outstanding (exclusive of Notes then owned by
          any one or more of the Company, any Subsidiary or any Affiliate) may
          exercise any right, power or remedy permitted to such holder or
          holders by law, and shall have, in particular, without limiting the
          generality of the foregoing, the right to declare the entire principal
          of, and all interest accrued on, all the Notes then outstanding to be,
          and such Notes shall thereupon become, forthwith due and payable,
          without any presentment, demand, protest or other notice of any kind,
          all of which are hereby expressly waived, and the Company shall
          forthwith pay to the holder or holders of all the Notes then
          outstanding the entire principal of, and interest accrued on, the
          Notes and, to the extent permitted by law, the Make-Whole Amount at

          (B)  ACCELERATION ON PAYMENT DEFAULT.  During the existence of an
     Event of Default described in Section 8.1(a) or Section 8.1(b), and
     irrespective of whether the Notes then outstanding shall have been declared

     who or which shall have not consented to any waiver with respect to such
     Event of Default may, at his or its option, by notice in writing to the
     Company, declare the Notes then held by such holder to be, and such Notes

     interest accrued thereon, without any presentment, demand, protest or other
     notice of any kind, all of which are hereby expressly waived, and the
     Company shall forthwith pay to such holder the entire principal of and

          (C)  VALUABLE RIGHTS.  The Company acknowledges, and the parties
     hereto agree, that the right of each holder to maintain its investment in
     the Notes free from repayment by the Company (except as herein specifically
     provided for) is a valuable right and that the provision for payment of a
     Make-Whole Amount by the Company in the event that the Notes are prepaid or
     are accelerated as a result of an Event of Default, is intended to provide
     compensation for the deprivation of such right under such circumstances.

          (D)  OTHER REMEDIES.  During the existence of an Event of Default and
     irrespective of whether the Notes then outstanding shall have been declared
     to be due and payable pursuant to Section 8.2(a) or Section 8.2(b) and
     irrespective of whether any holder of Notes then outstanding shall
     otherwise have pursued or be pursuing any other rights or remedies, any
     holder of Notes may proceed to protect and enforce its rights hereunder and
     under such Notes by exercising such remedies as are available to such
     holder in respect thereof under applicable law, either by suit in equity or
     by action at law, or both, whether for specific performance of any
     agreement contained herein or in aid of the exercise of any power granted
     herein, provided that the maturity of such holder's Notes may be
     accelerated only in accordance with Section 8.2(a) and Section 8.2(b).

          (e)  NONWAIVER. No course of dealing on the part of any holder of
     Notes nor any delay or failure on the part of any holder of Notes to
     exercise any right shall operate as a waiver of such right or otherwise
     prejudice such holder's rights, powers and remedies.

     8.3  ANNULMENT OF ACCELERATION OF NOTES.

     If a declaration is made pursuant to Section 8.2(a)(ii), then and in every
such case, the holders of at least sixty-six and two-thirds percent (66 2/3%) in
aggregate principal amount of the Notes then outstanding (exclusive of Notes
then owned by any one or more of the Company, any Subsidiaries and any
Affiliates) may, by written instrument filed with the Company, rescind and annul

     or Make-Whole Amount on, the Notes which shall have become due and payable
     by reason of such declaration under Section 8.2(a)(ii)) shall have been
     duly paid; and

          (c)  each and every other Default and Event of Default shall have been
     waived pursuant to Section 10.5 or otherwise made good or cured;

affect any subsequent Default or Event of Default or impair any right consequent

     corresponding to such Weighted Average Life to Maturity (one (1) with a
     longer maturity and one (1) with a shorter maturity, if available) shall be

               Prepaid Principal had not been so prepaid, and

     9.2  ACCOUNTING PRINCIPLES.

          (A) GENERALLY.  Unless otherwise provided herein, all financial
     statements delivered in connection herewith will be prepared in accordance
     with GAAP as in effect on the date of, or during the period covered by,
     such financial statements.  Where the character or amount of any asset or
     liability or item of income or expense, or any consolidation or other
     accounting computation is required to be made for any purpose hereunder, it
     shall be done in accordance with GAAP as in effect on the date of, or at
     the end of the period covered by, the financial statements from which such
     asset, liability, item of income, or item of expense, is derived, or, in
     the case of any such computation, as in effect on the date as of which such
     computation is required to be determined, provided, that if any term
     defined herein includes or excludes amounts, items or concepts that would
     not be included in or excluded from such term if such term was defined with
     reference solely to GAAP, such term will be deemed to include or exclude
     such amounts, items or concepts as set forth herein.

          (B) ACCOUNTING FOR SUBSIDIARIES.  Whenever a calculation based on the
     consolidated financial position or consolidated results of operations of
     the Company and the Restricted Subsidiaries (the "CONSOLIDATED ENTITIES")
     is required hereby

               (i) Investments by the Consolidated Entities in any Person other
          than a Restricted Subsidiary shall be carried at the lower of cost or
          Fair Market Value, and

               (ii) earnings of any Person other than a Restricted Subsidiary
          not distributed in the form of cash distributions to a Consolidated
          Entity shall not be included in any financial calculation of the
          Consolidated Entities.

          (C) CURRENCY.  With respect to any determination, consolidation or
     accounting computation required hereby, any amounts not denominated in the
     currency in which this Agreement specifies shall be converted to such
     currency in accordance with the requirements of GAAP (as such requirements
     relate to such determination, consolidation or computation) and, if no such
     requirements shall exist, converted to such currency in accordance with
     normal banking procedures, at the closing rate as reported in the most
     recent Wall Street Journal as of the date of such determination,
     consolidation or computation or, if no such quotation shall then be
     available, as quoted on such date by any bank or trust company reasonably
     acceptable to the Required Holders.

     9.3  DIRECTLY OR INDIRECTLY.

     Where any provision herein refers to action to be taken by any Person, or
which such Person is prohibited from taking, such provision shall be applicable
whether such action is taken directly or indirectly by such Person, including
actions taken by or on behalf of any partnership in which such Person is a
general partner.

     apply equally to all holders of Notes and shall be binding upon them and
     upon each future holder of any Note and upon the Company whether or not
     such Note shall have been marked to indicate such amendment or waiver.  No
     such amendment or waiver shall extend to or affect any obligation,

          (B)  PAYMENTS DUE ON HOLIDAYS.  If any payment due on, or with respect
     to, any Note shall fall due on a day other than a Business Day, then such

     such payment shall have so fallen due; provided that if all or any portion
     of such payment shall consist of a payment of interest, for purposes of
     calculating such interest, such payment shall be deemed to have been
     originally due on such first following Business Day, such interest shall
     accrue and be payable to (but not including) the actual date of payment,
     and the amount of the next succeeding interest payment shall be adjusted
     accordingly.  If any payment is to be made on the first Business Day
     following the day on which the same shall have fallen due, as provided in
     this Section 10.7(b) and is not so paid on such first Business Day,
     interest shall accrue thereon (to the extent permitted by applicable law)

     (in each case) the originally scheduled day of its payment.

          (C)  PAYMENTS, WHEN RECEIVED.  Any payment to be made to the holders
     of Notes hereunder or under the Notes shall be deemed to have been made on
     the Business Day such payment actually becomes available at such holder's
     bank prior to the close of business of such bank, provided that interest
     for one day at the non-default interest rate of the Notes shall be due on
     the amount of any such payment that actually becomes available to such
     holder at such holder's bank after 12:00 noon (local time of such bank).

                                                                  [Closing Date]



To the Persons Listed on
Annex I hereto

     Re:  Safety-Kleen Corp. (the "Company")

Ladies and Gentlemen:

     Reference is made to the separate Note Purchase Agreements dated as of
January 15, 1995 (collectively, the "Note Purchase Agreement"), between the
Company and each of the purchasers listed on Annex 1 attached thereto (the
"Purchasers"), which provide, among other things, for the issuance and sale by
the Company of its 8.05% Senior Notes due January 30, 1998 in the aggregate
principal amount of Fifty Million Dollars ($50,000,000).  The capitalized terms
used herein and not defined herein have the meanings specified by the Note
Purchase Agreement.

     I have acted as counsel to the Company in connection with the transactions
contemplated by the Note Purchase Agreement.  In acting as such counsel, I have
examined.

          (a)  the Note Purchase Agreement;

          (b) the Company's 8.05% Senior Notes due January 30, 1998 dated the
     date hereof, in the form of Exhibit A to the Note Purchase Agreement and in
     the principal amounts and with the registration numbers set forth on Annex
     1 to the Note Purchase Agreement (the "Notes");

          (c) the documents executed and delivered by the Company in connection
     with the transactions contemplated by the Note Purchase Agreement;

          (d) the bylaws and minute books of the Company and a certified copy of
     the articles of incorporation of the Company, as in effect on the date
     hereof;

          (e) a long-form good standing certificate from the state of
     incorporation of the Company, good standing certificates from the
     states/provinces of incorporation of each Restricted Subsidiary, and
     foreign good standing certificates for each of such corporations from each
     state where the Company or such Restricted Subsidiary is required to be in
     good standing;


                               EXHIBIT B1-1    Form of Company Counsel's Opinion
<PAGE>
 
          (f) a letter to Hebb & Gitlin from Cascade Capital Corporation dated
     the date hereof, making certain representations with respect to the manner
     in which the Notes were offered (the "Offeree Letter"); and

          (g) originals, or copies certified or otherwise identified to my
     satisfaction, of such other documents, records, instruments and
     certificates of public officials as I have deemed necessary or appropriate
     to enable me to render this opinion.

     In rendering this opinion, I have assumed that all signatures are genuine
(other than officers of the Company), that all documents submitted to me as
originals are genuine, that all copies submitted to me conform to the originals,
that all natural Persons have legal capacity, and as to documents executed by or
on behalf of Persons other than the Company.

          (i) that each such Person executing documents had the power to enter
     into and perform its obligations under such documents, and

          (ii) that such documents have been duly authorized, executed and
     delivered by, and are binding upon and enforceable against, such Persons.

     In rendering this opinion, I have relied, to the extent I deem necessary
and proper, on:

          (A) warranties and representations as to factual matters contained in
     the Note Purchase Agreement; and

          (B)  the Offeree Letter.

     I have no actual knowledge of any material inaccuracies in any of the facts
contained in the documents listed in Item (A) or (B).

     My opinion is based upon the laws of Wisconsin (with respect to corporate
law), Illinois, and federal law.  If the Note Purchase Agreement and the Notes
were governed by the laws of Illinois, my opinion would not vary materially from
that set forth below.

     Based on the foregoing, I am of the following opinions:

     1.   Each of the Company and each Restricted Subsidiary is a corporation
duly incorporated, validly existing and in good standing under the laws of its
state of incorporation and has all requisite corporate power and authority to
carry on its business and own its Property.

     2.   Each of the Company and each Restricted Subsidiary has duly qualified
and is in good standing as a foreign corporation in each jurisdiction where the
character of its Properties or the nature of its activities makes such
qualification necessary, except where the failure to so qualify and be in good
standing would not have a Material Adverse Effect.

     3.   To the best of my knowledge, all consents, approvals and
authorizations of, and all designations, declarations, filings, registrations,
qualifications, or recordations with, Governmental Authorities required on the
part of each of the Company and each Restricted Subsidiary have been obtained in
connection with the ownership of its Properties and the conduct of its
businesses, except where the failure to obtain any such consent, approval or


                               EXHIBIT B1-2    Form of Company Counsel's Opinion
<PAGE>
 
authorization with respect to such ownership and conduct would not have a
Material Adverse Effect.

     4.   There is no default or existing condition which with the passage of
time or notice, or both would result in a default by the Company or any
Restricted Subsidiary under any contract, lease or commitment known to me to
which any one or more of the Company or any Restricted Subsidiary is a party or
by which their respective Properties may be bound, except where such default
would not have a Material Adverse Effect.

     5.   To the best of my knowledge, there is no judgment, order, action,
suit, proceeding, inquiry, order or investigation, at law or in equity, before
any court or Governmental Authority, arbitration board or tribunal, pending or
threatened against the Company or any one or more of the Restricted
Subsidiaries, except for any such judgment, order, action, suit, proceeding,
inquiry, order or investigation that would not have a Material Adverse Effect.

     6.   The Company has the requisite corporate power and authority to execute
and deliver the Note Purchase Agreement, to issue and sell the Notes, and to
perform its obligations set forth in each of the Note Purchase Agreement and the
Notes.

     7.   Each of the Note Purchase Agreement and the Notes has been duly
authorized by all necessary corporate action on the part of the Company (no
action on the part of the stockholders of the Company being required in respect
thereof), has been executed and delivered by duly authorized officers of the
Company, and constitutes a legal, valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms.

     8.   The execution and delivery of the Note Purchase Agreement and the
Notes, and the issue and sale of the Notes, by the Company and the performance
by the Company of its obligations thereunder will not conflict with, constitute
a violation of, result in a breach of any provision of, constitute a default
under, or result in the creation or imposition of any Lien or encumbrance upon
any of its Property or the Property of a Restricted Subsidiary pursuant to the
articles of incorporation or bylaws of the Company or such Restricted
Subsidiary, any applicable statute, rule or regulation to which the Company or
any Restricted Subsidiary is subject, any agreement or instrument in respect of
borrowed money to which the Company or such Restricted Subsidiary is a party or
by which its respective Properties may be bound, or, to the best of my
knowledge, any other agreement or instrument to which the Company or such
Restricted Subsidiary is a party or by which its respective Properties may be
bound.

     9.   All consents, approvals and authorizations of, and all designations,
declarations, filings, registrations, qualifications and recordations with,
Governmental Authorities required on the part of the Company and the
Subsidiaries have been obtained in connection with the execution and delivery of
each of the Note Purchase Agreement and the Notes, the issue and sale of the
Notes, the use of the proceeds thereof, and the performance by the Company of
its obligations thereunder.

     10.  Under existing law, the Notes are not required to be registered under
the Securities Act of 1933, as amended, and the Company is not required to
qualify an indenture with respect thereto under the Trust Indenture Act of 1939,
as amended.


                               EXHIBIT B1-3    Form of Company Counsel's Opinion
<PAGE>
 
     11.  Neither the issuance of the Notes nor the intended use of the proceeds
of the Notes (as set forth in Section 2.18 of the Note Purchase Agreement) will
violate Regulations G, T or X of the Federal Reserve Board.

     12.  The Company

          (a) is not an "investment company" within the meaning of the
     Investment Company Act of 1940, as amended, and

          (b) is not a "holding company" or an "affiliate" of a "holding
     company," or a "subsidiary company" of a "holding company," or a "public
     utility" within the meaning of the Public Utility Holding Company Act of
     1935, as amended.

     13.  The Company has good title to all of the shares it purports to own of
the capital stock of each Restricted Subsidiary, free and clear in each case of
any perfected security interest, and to the best of my knowledge, any other
Lien.

     All opinions  herein contained with respect to the enforceability of
documents and instruments are qualified to the extent that:

          (a) the availability of equitable remedies, including without
     limitation, specific enforcement and injunctive relief, is subject to the
     discretion of the court before which any proceedings therefor may be
     brought; and

          (b) the enforceability of certain terms provided in the Note Purchase
     Agreement and the Notes may be limited by

               (i) applicable bankruptcy, reorganization, arrangement,
          insolvency, moratorium, fraudulent conveyance or similar laws
          affecting the enforcement of creditors' rights generally as at the
          time in effect,

               (ii) general principles of equity and the discretion of a court
          in granting equitable remedies (whether enforceability is considered
          in a proceeding at law or in equity).

     This opinion is delivered to you pursuant to Section 3.1 of the Note
Purchase Agreement.  The qualification of any opinion or statement herein by use
of the words "to the best of my knowledge" means that no information has come to
my attention which gives me actual knowledge that the matters, actions,
proceedings, items, documents or facts so qualified are not so as stated.
However, I have not undertaken any independent investigation or inquiry to
determine the existence or absence of such matters, actions, proceedings, items,
documents or facts.  I am qualified to practice law in the State of Illinois,
and I do not purport to be an expert on, or to express any opinion concerning,
any laws except the internal laws (without regard to choice of law rules) of the
State of Illinois and the federal law of the United States of America; however,
I am generally familiar with the corporation law of the State of Wisconsin and,
for the limited purpose of my opinions contained herein and limited solely to
Wisconsin corporation law, did not deem it necessary to obtain the opinion of
Wisconsin counsel.  My opinions express herein are limited to the effect of such
laws in effect on the date hereof, and no responsibility or undertaking is
hereby assumed to advise you of any subsequent changes in such laws or of the


                               EXHIBIT B1-4    Form of Company Counsel's Opinion
<PAGE>
 
applicability or effect of the laws of any other jurisdiction.  Subsequent
holders of the Notes may rely on this opinion as if it were addressed to them.
Hebb & Gitlin may rely on this opinion for the sole purpose of rendering their
opinion to be rendered pursuant to Section 3.1 of the note Purchase Agreement.

                                         Very truly yours,

                  FORM OF PURCHASER'S SPECIAL COUNSEL OPINION

                         [LETTERHEAD OF HEBB & GITLIN]


                                                                  [Closing Date]


To the Persons Listed on
Annex 1 hereto

     Re:  Safety-Kleen Corp. (the "Company")

Ladies and Gentlemen:

     Reference is made to the separate Note Purchase Agreements dated as of
January 15, 1995 (collectively, the "Note Purchase Agreement"), between the
Company and each of the purchasers listed on Annex 1 attached thereto (the
"Purchasers"), which provide, among other things, for the issuance and sale by
the Company of its 8.05% Senior Notes due January 30, 1998 in the aggregate
principal amount of Fifty Million Dollars ($50,000,000).  The capitalized terms
used herein and not defined herein have the meanings specified by the Note
Purchase Agreement.

     We have acted as special counsel to the Purchasers in connection with the
transactions contemplated by the Note Purchase Agreement.  In acting as such
counsel, we have examined:

          (a) the Note Purchase Agreement;

          (b) the Company's 8.05% Senior Notes due January 30, 1998 dated the
     date hereof, in the form of Exhibit A to the Note Purchase Agreement and in
     the principal amounts and with the registration numbers set forth on Annex
     1 to the Note Purchase Agreement (the "Notes");

          (c) a certificate of the President and Chief Executive Officer of the
     Company, substantially in the form attached to the Note Purchase Agreement
     as Exhibit C;

          (d) a certificate of the Secretary of the Company, substantially in
     the form attached to the Note Purchase Agreement as Exhibit D;

          (e) a letter to Hebb & Gitlin from Cascade Capital Corporation dated
     the date hereof, making certain representations with respect to the manner
     in which the Notes were offered (the "Offeree Letter");

          (f) the opinion of Hyman K. Bielsky, counsel to the Company and the
     Subsidiaries, dated the date hereof; and

                    EXHIBIT B2-1     FORM OF PURCHASER'S SPECIAL COUNSEL OPINION

<PAGE>
 
          (g) originals, or copies certified or otherwise identified to our
     satisfaction, of such other documents, records, instruments and
     certificates of public officials as we have deemed necessary or appropriate
     to enable us to render this opinion.

     In rendering our opinion, we have assumed that all signatures are genuine,
that all documents submitted to us as originals are genuine, that all copies
submitted to us conform to the originals, that all natural Persons have legal
capacity, and as to documents executed by or on behalf of Persons other than the
Company,

          (i) that each such Person executing documents had the power to enter
     into and perform its obligations under such documents, and

          (ii) that such documents have been duly authorized, executed and
     delivered by, and are binding upon and enforceable against, such Persons.

     In rendering our opinion, we have relied, to the extent we deem necessary
and proper, on:

          (a) warranties and representations as to factual matters contained in
     the Note Purchase Agreement;

          (b) the Offeree Letter; and

          (c) said opinion of Hyman K. Bielsky with respect to all questions
     governed by Wisconsin law and with respect to all questions concerning the
     due incorporation, valid existence, corporate power and authority of, and
     the authorization, execution and delivery of instruments by, the Company
     (except that we have made an independent examination of a certified copy of
     the articles of incorporation of the Company, and certificates of officers
     of the Company setting forth its bylaws and corporate resolutions
     authorizing its participation in the transactions contemplated by the Note
     Purchase Agreement); based on such investigation as we have deemed
     appropriate, said opinion is satisfactory in form and scope to us and in
     our opinion the Purchasers and we are justified in relying thereon.

     Based on the foregoing, we are of the following opinions:

     1.   The Company is a corporation duly incorporated, validly existing and
in good standing under the laws of the state of Wisconsin.

     2.   The Company has all requisite corporate power and authority to
execute and deliver the Note Purchase Agreement, to issue and sell the Notes,
and to perform its obligations set forth in each of the Note Purchase Agreement
and the Notes.

     3.   Each of the Note Purchase Agreement and the Notes has been duly
authorized by all necessary corporate action on the part of the Company, has
been executed and delivered by one or more duly authorized officers of the
Company, and constitutes a legal, valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms.

                    EXHIBIT B2-2     FORM OF PURCHASER'S SPECIAL COUNSEL OPINION

<PAGE>
 
     4.   The execution and delivery of the Note Purchase Agreement and the
Notes, and the issue and sale of the Notes, by the Company and the performance
by the Company of its obligations thereunder will not conflict with, result in a
breach of any provision of, constitute a default under, or result in the
creation or imposition of any Lien upon any of its Properties pursuant to, the
articles of incorporation or bylaws of the Company.

     5.   No consents, approvals or authorizations of governmental authorities
to the Company are required under the laws of the United States of America or
the State of New York in connection with the execution and delivery of each of
the Note Purchase Agreement and the Notes and the offer, issue, sale and
delivery of the Notes and the performance of the Company thereunder.  Our
opinion in this Section 5 is based solely on a review of generally applicable
laws of the United States of America and New York and not on any search with
respect to, or review of, any orders, decrees, judgments or other determinations
specifically applicable to the Company.

     6.   Under existing law, the Notes are not required to be registered under
the Securities Act of 1933, as amended, and the Company is not required to
qualify an indenture with respect thereto under the Trust Indenture Act of 1939,
as amended.

     All opinions herein contained with respect to the enforceability of
documents and instruments are qualified to the extent that:

          (a) the availability of equitable remedies, including without
     limitation, specific enforcement and injunctive relief, is subject to the
     discretion of the court before which any proceedings therefor may be
     brought; and

          (b) the enforceability of certain terms provided in the Note Purchase
     Agreement and the Notes may be limited by

               (i) applicable bankruptcy, reorganization, arrangement,
          insolvency, moratorium, fraudulent conveyance, or similar laws
          affecting the enforcement of creditors' rights generally as at the
          time in effect, and

               (ii) common law or statutory requirements with respect to
          commercial reasonableness.

     This opinion is delivered to you pursuant to Section 3.1 of the Note
Purchase Agreement.  We express no opinion as to the law of any jurisdiction
other than the law of New York, United States federal law and, as expressly set
forth in the next sentence, Wisconsin.  To the extent that the opinions
expressed herein involve matters governed by the laws of Wisconsin, we have
relied upon the aforementioned opinion of Hyman K. Bielsky and our conclusions
as to such matters are subject to the same assumptions, limitations and
qualifications as are contained in said opinion.  Subsequent holders of the
Notes may rely on this opinion as if it were addressed to them.

                         Very truly yours,

                     SAFETY-KLEEN MANAGEMENT INCENTIVE PLAN
                     --------------------------------------

                                February 3, 1995



The Directors of Safety-Kleen Corp. have heretofore decided to compensate their
officers and key management personnel under a compensation plan that will
include base salary plus incentive bonus.  The purpose of the incentive plan is
to supplement by incentive bonuses the remuneration for officers and key
management personnel which is competitive externally, equitable internally, and
properly rewarding for performance in the responsibility assigned.  On the
recommendation of the Compensation Committee, the following Management Incentive
Plan is hereby established for officers and key management personnel of the
Company.

I.   Calculation of Management Incentive Fund
----------------------------------------------

     In recognition of the fact that one of the key corporate goals is to
     provide Safety-Kleen Shareholders a better-than-average return on corporate
     equity, the incentive fund, consisting of both a formula and discretionary
     fund, will be created as follows:

     A.  Utilization of the Standard & Poor's 500 as a Comparison Group
     ------------------------------------------------------------------

         For each Plan year, the  return on beginning-of-year equity (ROE) for
         each firm comprising the Standard & Poor's 500 will be calculated,
         arrayed and summarized in descending ROE order for the four consecutive
         calendar quarters ending with the third quarter of the previous year.

     B.  Determination of Qualifying ROE Level for Generation of Incentive Fund
     --------------------------------------------------------------------------

         The ROE for the 325th company in the array will determine the
         qualifying level for the minimum percentage of earnings allocable to
         the formula portion of the incentive fund. In other words, in order for
         any incentive fund to be created in a given year, Safety-Kleen must
         attain an ROE for that year that would place it among the top 65% of
         the five hundred publicly held companies comprising the Standard &
         Poor's 500.

     C.  Determination of ROE Level Required for Maximum Incentive Fund
     ------------------------------------------------------------------

         In order to qualify for the maximum percentage of earnings allocable to
         the formula portion of the Incentive Fund in a given year, Safety-Kleen
         must attain an ROE for that year that would place it among the top 25%
         in the array.

                                       1
<PAGE>
 
     D.  Determination of Formula Incentive Fund Factor
     --------------------------------------------------

         At the minimum qualifying ROE level (I.B.), a formula incentive fund
         consisting of 1% of consolidated pretax earnings will be created. This
         factor will rise on a graduated basis to a maximum of 5.0% of
         Consolidated Pretax Earnings when the maximum level (I.C.) is attained
         (see Table 1).  The formula fund factor calculation for each ensuing
         fiscal year will be reviewed by the Compensation Committee of the Board
         prior to the development of that year's incentive plan.

     E.  Calculation of the Discretionary Element of the Plan
     --------------------------------------------------------

         In addition to the fund created by the above calculations, an
         additional fund consisting of an amount not exceeding 50% of the
         formula amount will be available for discretionary incentive
         allocations. The allocation of corporate pretax earnings available for
         incentive purposes, therefore, will be limited to a maximum of 7.5% of
         pretax earnings.

II.  Allocation of Funds
------------------------

     A.  Determination of Plan Participants
     --------------------------------------

         Determination of who will participate in the Plan will be developed
         each year by the Chief Executive Officer (President) and the Chairman
         of the Board (Chairman) in consultation with other corporate officers.
         Such eligibility will be in accordance with job responsibility and
         salary grade. The list of job classifications to be included in the
         Plan will be submitted at the beginning of each calendar year for
         review by the Compensation Committee.

     B.  Determination of Individual Fund Shares
     -------------------------------------------

         The percentage share of the formula incentive fund for each officer
         participant will be recommended by the President and the Chairman and
         submitted to the Compensation Committee for its approval at the
         beginning of each calendar year. Non-officer participant percent shares
         will be developed by the President and the Chairman in consultation
         with other officers.

     C.  Payment of Annual Incentive
     -------------------------------

         The calculation of the formula incentive fund will be based on final
         audited year-end financial statements, utilizing the method described
         previously. The individual share calculations for each officer for the
         formula incentive resulting from the above calculation, together with
         the recommended discretionary share, which can range from 0 to 50% of
         the formula amount, shall be

                                       2
<PAGE>
 
         submitted to the Compensation Committee for its final approval during
         the first quarter of the year following the fiscal year involved.

         The President and the Chairman will recommend the discretionary amount
         for each officer based on his analysis of each individual's performance
         during the year. A non-officer participant's discretionary share will
         be recommended by the participant's immediate supervisor for approval
         by the President and the Chairman.

III. Incentive Plan Participation and Communications
----------------------------------------------------

     The President and the Chairman shall notify the Compensation Committee of
     the Board regarding officers and the key management positions that will be
     included in the Plan for the current year.  Such a list should be
     determined as early as possible in any fiscal year and no later than the
     end of the first quarter of each fiscal year.  Early identification of
     participants is desirable to provide maximum opportunity for communicating
     throughout the year regarding company performance and each individual
     participant's related bonus opportunity, thereby maximizing the
     effectiveness of the Incentive Plan.

IV.  General Provisions
-----------------------

     A.  Plan Eligibility
     --------------------

         To be eligible to participate under the plan, an officer or employee
         must be actively employed with the company on the last working day of
         the year for which the year's compensation is payable; provided, that
         in the event a participant's employment is terminated prior to year-end
         by reason of death occurring after June 1, his share of the formula
         incentive fund will be adjusted on the basis of his full-year share,
         prorated for the period of his actual employment.

     B.  Less Than Full-Year's Employment
     ------------------------------------

         In the event a participant's employment commences after January 1,
         adjustment of his share of the formula incentive fund will be on the
         basis of his full-year share, prorated for the period of the
         participant's actual employment.

     C.  Definition of Consolidated Pretax Earnings
     ----------------------------------------------

         For purposes of determining the dollar amount to be set aside for the
         formula portion of the fund as above provided, consolidated pretax
         earnings shall consist of the reported earnings before income tax, and
         before deducting the amount calculated for both the formula and the
         discretionary portions of the

                                       3
<PAGE>
 
         incentive fund, as reflected in the audited statements of that year,
         subject to the following limitations: profits or losses on the sale or
         other distribution of fixed or capital assets not in the ordinary
         course of business shall be excluded in the determination of profits.

     D.  Definition of Return on Beginning-of-Year Equity
     ----------------------------------------------------

         Return on beginning-of-year equity shall be calculated on the basis of
         consolidated pretax earnings as defined in IV.C., less the expense
         provision for both the formula and discretionary portions of the
         incentive fund, and less the applicable income tax provision.

V.   Final Responsibility for Plan Administration
-------------------------------------------------

     Notwithstanding the foregoing provisions, all matters pertaining to the
     administration of this Incentive Compensation Plan, including but not
     limited to the determination of the Fund amount, selection of participants,
     amounts of awards to be paid to individual participants, and other policy
     matters, shall be within the sole discretion of the Board of Directors.

     This plan may be revoked, amended or revised by the Board of Directors of
     the Company but no revocation, amendment or revision shall affect a
     participant's granted percentage share of the Fund.

                           GENERAL SEVERANCE BENEFIT
                           -------------------------

    4.1  Entitlement.  If the Employee's employment by the Company, any parent
or subsidiary of the Company or any successor to the Company or any parent or
subsidiary of the Company is terminated for reasons other than death, a
Voluntary Termination or a Discharge for Cause following a Change of Control but
not later than the third anniversary of the Change of Control, the Company shall
pay the Employee forthwith a lump sum severance benefit equal to three times the
sum of (a) and (b) where: (a) equals the Employee's annual rate of salary
(excluding bonuses) in effect on the date of the Employee's termination
(provided that such rate shall in no event be less than the rate in effect on
the date of Change of Control) and (b) equals the greater of (i) the bonus which
the Employee received in the year prior to the year in which the Employee's
termination occurs, or if larger, the year prior to the Change of Control or
(ii) the maximum bonus to which the Employee would be entitled for the year in
which the Employee's termination occurs.  If the Employee's employment by the
Company, any parent or subsidiary of the Company or any successor to the Company
or any parent or subsidiary of the  Company is terminated later than the third
anniversary of the Change of Control there shall be no severance benefit payable
hereunder.

    4.2  No Duplication of Benefits.  The severance benefits provided for herein
are in lieu of severance benefit provisions under the Company severance pay
policies and plans or under any other contract between the Company or any
parent, subsidiary or affiliate thereof and the Employee, including, but not
limited to, benefits payable under

                                      -5-

<PAGE>
 
employment agreements by virtue of termination of employment prior to the
expiration of the agreement.  The Employee shall not be entitled to any
severance benefits under such policies, plans or other contracts unless the
benefits provided thereunder are greater than the severance benefits payable
hereunder, in which case the severance benefits under such other policies, plans
or contracts shall be provided in lieu of the severance benefits hereunder.

                                   ARTICLE V.
                                   ----------
                                  TAX BENEFITS
                                  ------------

    5.1  Limit On Benefits.  Notwithstanding any of the provisions of this
Agreement to the contrary, if any payments under this Agreement ("Agreement
Parachute Payments") count in determining whether the Employee has received
"parachute payments" (as defined in Code Section 280G(b)(2)), and if the sum of
the present values (as determined under Code Section 280G(d)(4)) of (a) the
Agreement Parachute Payments to the Employee, plus (b) any other payments or
benefits which count in determining whether the Employee has received  parachute
payments excluding payments or benefits attributable to options granted under
the Company's stock option plans ("Other Parachute Payments"), received by the
Employee from the Company or any other member of the same affiliated group as
the Company (as defined in Code Section 1504, determined without regard to Code
Section 1504(b)) equals or exceeds three (3) times the Employee's base amount
(as defined in Code Section 280G(b)(3)), then the amount of the Agreement
Parachute Payments shall be reduced to the extent necessary so that

                                      -6-

<PAGE>
 
the sum of the present values of the Agreement Parachute Payments and Other
Parachute Payments equals three (3) times the Employee's base amount less $1.00.

    5.2  Gross-up.

    (a)  If it is determined (in the reasonable opinion of the Company or in the
opinion of counsel to the Company if such an opinion is requested by the
Employee) that any payment or benefit made pursuant to this Agreement or
otherwise, received or deemed received by the Employee from the Company or any
other member of the same affiliated group as the Company (as defined in Code
Section 1504, determined without regard to Code Section 1504(b)) (collectively
referred to as the "Payments") is or will become subject to any excise tax under
Section 4999 of the Code or any similar tax payable under any federal, state,
local or other law ("Excise Taxes"), then the Company shall, immediately upon
such determination, pay the Employee an amount equal to the sum of (i) any such
Excise Taxes, plus (ii) the amount necessary to reimburse the Employee for any
federal, state, local or other income, excise or other taxes payable by the
Employee with respect to (A) the amount of Excise Taxes reimbursement herein
provided, and (B) the amount paid to the Employee as reimbursement of any such
federal, state, local or other income, excise or other taxes, as determined (for
both clauses (A) and (B) hereof) in accordance with the formula set forth on
Exhibit I attached hereto.  All determinations hereunder shall be made in
adequate time to permit the Employee to prepare and file his individual tax
returns in a timely fashion.

    (b)  The Company, in determining whether the Payments are subject to Excise
Taxes, may have reasonably concluded that certain items are neither subject to
Excise

                                      -7-
<PAGE>
 
Taxes nor to be counted in determining whether Payments are subject to Excise
Taxes (such items hereinafter referred to as "Non-Parachute Items").  If at a
later date, it is determined (pursuant to final regulations or published rulings
of the IRS, final judgment of a court of competent jurisdiction or, if requested
by Employee, an opinion of counsel to the Company) that any of the Non-Parachute
Items are subject to Excise Taxes, or are to be counted in determining whether
any of the Payments are subject to Excise Taxes, with the result that the amount
of Excise Taxes payable by the Employee is greater than the amount so determined
by the Company pursuant to paragraph (a) above, then the Company shall pay the
Employee, in accordance with the formula set forth on Exhibit I, an amount equal
to the sum of (i) such additional Excise Taxes (ii) any interest, fines,
penalties, expenses, and other costs incurred by Employee and resulting from the
Employee having taken a position that payments are not subject to Excise Taxes
in accordance with the determination made in paragraph (a), above; plus (iii) an
amount necessary to reimburse the Employee for any federal, state, local, or
other income, excise, or other taxes payable by the Employee with respect to (A)
the amounts specified in subparagraphs (i) and (ii) above, and (B) the
reimbursement provided by this subparagraph (iii).

    5.3  Consultation.  At the Company's reasonable request, the Employee shall
consult with the Company regarding (a) the preparation and filing of the
Employee's federal income and excise tax returns for any year in which any
Payments are received, and (b) any federal tax issues which may arise with
respect to any Payments made in connection with a Change in Control.  At the
Company's request, Employee shall retain

                                      -8-

<PAGE>
 
counsel and other experts and consultants reasonably satisfactory to Company in
connection with any or all of the matters described in items (a) and (b) above
and Company shall reimburse Employee (in accordance with Section 6.2 hereof) for
all fees, expenses and costs (including audit costs, attorneys' fees and
expenses, and court costs) incurred by Employee as a result of the retention of
such counsel and other experts and consultants.  Anything to the contrary herein
notwithstanding, the Employee shall not in any way be restricted from making
such disclosure in his individual tax returns with respect to the Payments as he
shall deem reasonable and appropriate.

                                  ARTICLE VI.
                                  -----------
                                 MISCELLANEOUS
                                 -------------

    6.1  No Employment Guarantee.  This Agreement shall not be deemed to entitle
the Employee to continued employment with the Company, any parent or subsidiary
of the Company or any successor to the Company or any parent or subsidiary of
the Company and the rights of the Company, any parent or subsidiary of the
Company or any successor to the Company or any parent or subsidiary of the
Company to terminate the employment of the Employee shall continue as fully as
if this Agreement were not in effect.

    6.2  Expenses.

    (a) If the Employee incurs (i) legal or other fees and expenses in an effort
to establish entitlement to benefits under this Agreement, regardless of whether
the Employee ultimately prevails, or (ii) legal, accounting and other fees and
expenses in connection with the retention of counsel and other experts and
consultants as requested

                                      -9-


<PAGE>
 
by the Company pursuant to Section 5.3 hereof, the Company shall reimburse him
for such fees and expenses.

    (b) Reimbursement of fees and expenses described in paragraph (a), above,
shall be made monthly during the course of any action upon the written
submission of a request for reimbursement together with proof that the fees and
expenses were incurred.

    6.3  Unfunded Obligation.  The obligation of the Company under this
Agreement shall be unfunded and unsecured, and the Company shall not be required
to segregate any assets that may at any time be required to provide the benefits
under this Agreement.

    6.4  Assignment, Successors.  The Company may freely assign its respective
rights and obligations under this Agreement to a successor of the Company's
business, without the prior written consent of the Employee.  This Agreement
shall be binding upon and inure to the benefit of the Employee and his estate
and the Company and any assignee of or successor to the Company.

    6.5  Beneficiary.  If the Employee dies prior to receiving all of the
benefits payable hereunder, such benefits when payable shall be paid to the
beneficiary designated in writing by the Employee and if no such beneficiary is
designated, to the Employee's estate.

    6.6  Nonalienation of Benefits.  Benefits payable under this Agreement shall
not be subject in any manner to anticipation, alienation, sale, transfer,
assignment, pledge, encumbrance charge, garnishment, execution or levy of any
kind, either voluntary or involuntary, prior to actually being received by  the
Employee; and any attempt to

                                      -10-
<PAGE>
 
anticipate, alienate, sell, transfer, assign, pledge, encumber, charge, garnish,
execute on, levy or otherwise dispose of any right to benefits payable
hereunder, shall be void.

    6.7  Severability.  If all or any part of this Agreement is declared by any
court or governmental authority to be unlawful or invalid, such unlawfulness or
invalidity shall not serve to invalidate any portion of this Agreement not
declared to be unlawful or invalid.  Any Section or part of a Section so
declared to be unlawful or invalid shall, if possible, be construed in a manner
which will give effect to the terms of such Section or part of a Section to the
fullest extent possible while remaining lawful and valid.

    6.8  Amendment and Waiver.  Subject to Section 5.9, this Agreement shall not
be altered, amended or modified except by written instrument executed by the
Company and Employee.  A waiver of any term, covenant, agreement or condition
contained in this Agreement shall not be deemed a waiver of any other term,
covenant, agreement or condition, and any waiver of any default in any such
term, covenant, agreement or condition shall not be deemed a waiver of any later
default thereof or of any other term, covenant, agreement or condition.

    6.9  Cancellation.  The Company may, at any time prior to a Change of
Control, unilaterally cancel this Agreement on behalf of all parties hereto by
notifying the Employee of such cancellation in writing at least twelve (12)

                                Gross-up Formula

    Any payment made pursuant to Section 5.2 of the Agreement (a "Gross-up
Payment") shall be calculated as follows:

         A.  The Gross-up Payment shall be the product of (i) the amount of the
    Excise Taxes (and in the case of Section 5.2(b), any interest, fines,
    penalties, expenses, and other costs relating to Excise Taxes) incurred by
    the Employee times (ii) a fraction the numerator of which is 1, and the
    denominator of which is 1 minus the combined total rates expressed as a
    fraction, determined in accordance with paragraph B hereof, of all federal,
    state, local and other income and other taxes and any Excise Taxes
    applicable to such Gross-up Payment.  In the event that different rates of
    tax are applicable to any portion of a Gross-up Payment, the denominator of
    the fraction set forth in clause (ii) above shall be 1 minus the combined
    total of the weighted average rates expressed as a fraction, determined in
    accordance with paragraph B hereof, of all federal, state, local and other
    income and other taxes and any Excise Taxes applicable to such Gross-up
    Payment.

         B.  For purposes of determining the denominator of the fraction set
    forth in clause (ii) of paragraph A hereof, the rates of federal, state,
    local and other income and other taxes and Excise Taxes shall be the actual
    rates of such taxes (giving effect to the Employee's net effective tax rates
    determined net of the benefit of any tax deduction or tax credit); provided,
    however, that if the combined total of such rates shall exceed 75%, such
    combined total shall be deemed to be 75%.

                            ARTICLE 2.  THE CREDIT.

         Section 2.01.  The Syndicated Loans.  Subject to the terms and
conditions of this Agreement, each of the Banks severally agrees to make
Syndicated Loans to the Borrower from time to time from and including the date
hereof to but excluding the Termination Date for such Bank up to but not
exceeding the amount of its Commitment.  The Syndicated Loans may be outstanding
as Variable Rate Loans or Eurodollar Loans or CD Loans (each a "type" of Loans).
The Loans of each type of each Bank shall be made and maintained at such Bank's
Lending Office for such type of Loans.


         Section 2.02.  The Money Market Loans.

         (a)  In addition to borrowings of Syndicated Loans, the Borrower may,
as set forth in this Section 2.02, request the Banks to make offers to make
money market loans to the Borrower as provided below (the "Money Market Loans").
The Banks may, but shall have no obligation to, make such offers and the
Borrower may, but shall have no obligation to, accept any such offers in the
manner set forth in this Section 2.02.

         (b)  There may be no more than three different Interest Periods for
Money Market Loans outstanding at the same time; and the aggregate principal
amount of all Money Market Loans, together with the aggregate principal amount
of all Syndicated Loans, at any one time outstanding shall not exceed the
aggregate amount of the Commitments at such time.

         (c)  When the Borrower wishes to request offers to make Money Market
Loans, it shall give the Agent (which shall promptly notify the Banks) notice (a
"Money Market Quote Request") so as to be received no later than 11:00 a.m. New
York time on the Banking Day next preceding the date of borrowing proposed
therein, specifying with respect to each Money Market Loan offer requested:

         (i)    the proposed date of such borrowing (a "Money Market
Borrowing"), which shall be a Banking Day;

         (ii)   the aggregate amount of such Money Market Borrowing, which shall
be at least $4,000,000 (and in larger multiples of $1,000,000) but shall not
cause the limits specified in Section 2.02(b) hereof to be violated; and

         (iii)  the duration of the Interest Period applicable thereto.

         The Borrower may request offers to make Money Market Loans to be
borrowed on no more than two different dates and for up to three different
Interest Periods in a single Money Market Quote Request; provided that the
request for each separate Interest Period shall be deemed to be a separate Money
Market Quote Request for a separate Money Market Borrowing.  Except 

                                      -10-

<PAGE>
 
as otherwise provided in the preceding sentence, no more than three Money Market
Quote Requests shall be given within each calendar week.

         (d)(i)  Each Bank may submit a money market quote containing an offer
to make a Money Market Loan in response to any Money Market Quote Request (a
"Money Market Quote"); provided that, if the Borrower's request under Section
2.02(c) hereof specified more than one borrowing date or more than one Interest
Period, such Bank may make a single submission containing a separate offer for
each such borrowing date and Interest Period and each such separate offer shall
be deemed to be a separate Money Market Quote.  Each Money Market Quote must be
submitted to the Agent not later than 11:00 a.m. New York time on the first
proposed date of borrowing; provided that any Money Market Quote submitted by
the Agent (or its Applicable Lending Office) may be submitted, and may only be
submitted, if the Agent (or such Applicable Lending Office) notifies the
Borrower of the terms of its offer not later than 10:45 a.m. New York time on
the first proposed date of borrowing.  Subject to Sections 4.02, 3.01 and 9
hereof, any Money Market Quote so made shall be irrevocable.

         (ii)  Each Money Market Quote shall specify:

              (A)  the proposed date of borrowing and the Interest Period
         therefor;

              (B)  the principal amount of the Money Market Loan for which each
         such offer is being made, which principal amount (x) may be greater
         than or less than the unused Commitment of the quoting Bank, (y) shall
         be at least $1,000,000 or a larger multiple of $100,000, and (z) may
         not exceed the principal amount of the Money Market Borrowing for which
         offers were requested;

              (C)  the rate of interest per annum (rounded upwards, if
         necessary, to the nearest 1/10,000th of 1%), which shall be a set rate
         (the "Money Market Rate") offered for each such Money Market Loan;
         provided, however, that if more than one Money Market Rate is offered
         for such Money Market Loan, the Money Market Quote shall also specify
         the portion of the principal amount of the Money Market Loan to which
         each such Money Market Rate relates;

              (D)  the identity of the quoting Bank.

No Money Market Quote shall contain qualifying, conditional or similar language
or propose terms other than or in addition to those set forth in the applicable
Money Market Quote Request and, in particular, no Money Market Quote may be
conditioned upon acceptance by the Borrower of all (or some specified minimum)
of the principal amount of the Money Market Loan for which such Money Market
Quote is being made.

         (e)  The Agent shall as promptly as practicable after such Money Market
Quote is submitted (but in any event not later than 11:15 a.m. New York Time)
notify the Borrower of the terms (i) of any Money Market Quote submitted by a
Bank that is in accordance with Section 2.02(d) hereof and (ii) of any Money
Market Quote that amends, modifies or is otherwise 
 
                                      -11-

<PAGE>
 
inconsistent with a previous Money Market Quote submitted by such Bank with
respect to the same Money Market Quote Request. Any such subsequent Money Market
Quote shall be disregarded by the Agent unless such subsequent Money Market
Quote is submitted solely to correct a manifest error in such former Money
Market Quote. The Agent's notice to the Borrower shall specify (A) the aggregate
principal amount of the Money Market Borrowing for which offers have been
received and (B) the respective principal amounts and Money Market Rates, as the
case may be, so offered by each Bank (identifying the Bank that submitted each
Money Market Quote).

         (f)  Not later than 11:30 a.m. New York time on the proposed date of
borrowing the Borrower shall give the Agent irrevocable notice of its acceptance
or nonacceptance of the offers so notified to it pursuant to Section 2.02(e)
hereof and the Agent shall promptly notify each affected Bank.  In the case of
acceptance, such notice shall specify the aggregate principal amount of offers
for each Interest Period that are accepted.  The Borrower may accept any Money
Market Quote in whole or in part (provided that any Money Market Quote accepted
in part from any Bank shall be at least $1,000,000 and in multiples of
$100,000); provided that:

              (i)    the aggregate principal amount of each Money Market
         Borrowing may not exceed the applicable amount set forth in the related
         Money Market Quote Request;

              (ii)   the aggregate principal amount of each Money Market
         Borrowing shall be at least $4,000,000 (and in larger multiples of
         $1,000,000) but shall not cause the limits specified in Section 2.02(b)
         hereof to be violated;

              (iii)  acceptance of offers may only be made in ascending order of
         Money Market Rates except that should any Banks submit Money Market
         Quotes in which the Money Market Rate is within 1/16th of 1% of the
         lowest Money Market Rate received by the Agent with respect to that
         Money Market Quote Request, the Borrower shall have the right to advise
         the Agent that, on a selected basis, it is accepting such Money Market
         Quotes from Banks whose Money Market Rates so received by the Agent are
         within such range, not necessarily in ascending order, provided that:
         (A) the Bank with the lowest Money Market Rate for such Money Market
         Quote shall in any event be allocated at least 70% of that portion of
         the principal amount to which such Money Market Rate relates quoted by
         such lowest bidding Bank in the Money Market Quote; (B) all other
         conditions set forth in this Section 2.02(f) hereof are met;

              (iv)   the Borrower may not accept any offer where the Agent has
         advised the Borrower that such offer fails to comply with Section
         2.02(d)(ii) hereof or otherwise fails to comply with the requirements
         of this Agreement.

Subject to the provisions of Section 2.02(f)(iii), if offers are made by two or
more Banks with the same Money Market Rates for a greater aggregate principal
amount than the amount in respect of which offers are accepted for the related
Interest Period, the principal amount of Money Market Loans in respect of which
such offers are accepted shall be allocated by the Borrower among such 
 
                                      -12-
 

<PAGE>
 
Banks as nearly as possible (in minimum amounts of $1,000,000 for each Bank and
in multiples of $100,000) in proportion to the aggregate principal amount of
such offers. Determinations by the Borrower of the amounts of Money Market Loans
shall be conclusive in the absence of manifest error.
 
         (g)  Any Bank whose offer to make any Money Market Loan has been
accepted shall, not later than 3:00 p.m. New York time on the date specified for
the making of such Loan, make the amount of such Loan available to the Agent at
the Principal Office in immediately available funds.  The amount so received by
the Agent shall, subject to the terms and conditions of this Agreement, be made
available to the Borrower on such date by depositing the same, in immediately
available funds, in an account designated to the Agent in writing by the
Borrower.

         (h)  The amount of any Money Market Loan made by any Bank shall
constitute a utilization of such Bank's Commitment.

         Section 2.03.  The Notes; Repayment.  (a) The Syndicated Loans of each
Bank shall be evidenced by a single promissory note in favor of such Bank in the
form of Exhibit A, dated the date of this Agreement, duly completed and executed

promissory note in favor of such Bank in the form of Exhibit B, dated the date
of this Agreement, duly completed and executed by the Borrower.

         (c)  The Borrower will pay to the Agent for account of each Bank the
principal of each Loan made by such Bank, and each Loan shall mature, on the
last day of the Interest Period therefor.

         Section 2.04.  Purpose.  The Borrower shall use the proceeds of the
Loans for working capital.  Such proceeds shall not be used for the purpose,
whether immediate, incidental or ultimate, of buying or carrying "margin stock"
within the meaning of Regulation U.

         Section 2.05.  Syndicated Borrowings.  The Borrower shall give the

provided in Section 2.09.  Not later than 1:00 p.m. New York City time on the
date of such borrowing, each Bank shall, through its Lending Office and subject
to the conditions of this Agreement, make the amount of the Syndicated Loan to
be made by it on such day available to the Agent, at the Principal Office and in
immediately available funds for the account of the Borrower.  The amount so
received by the Agent shall, subject to the conditions of this Agreement, be
made available to the Borrower, in immediately available funds, by the Agent
crediting an account of the Borrower designated to the Agent in writing by the
Borrower.

         Section 2.06.  Prepayments.  The Borrower shall have the right to

aggregate principal amount of the Loans exceeds the aggregate amount of the
Commitments, the Borrower shall pay or repay the Loans on the date of such
reduction or termination in an aggregate principal amount equal to the excess,
together with interest thereon accrued to the date of such payment or repayment
and any amounts payable pursuant to Section 3.05 in connection therewith.

         Section 2.07.  Interest Periods.  In the case of each Loan, the

limitations:  (a) no Interest Period may extend beyond the Termination Date for
each Bank; (b) notwithstanding clause (a) above, no Interest Period for a Fixed
Rate Loan shall have a duration less than one month (in the case of a Eurodollar
Loan) or 30 days (in the case of a CD Loan), and if any such proposed Interest
Period would otherwise be for a shorter period, such Interest Period shall not
be available; (c) if an Interest Period would end on a day which is not a

fixed rate equal to the Fixed Rate plus the Margin and (iii) for a Money Market
Loan, at a fixed rate equal to Money Market Rate for such Loan for the Interest
Period therefor quoted by the Bank making such Loan in accordance with Section
2.02 hereof.  If the principal amount of any Loan and any other amount payable
by the Borrower hereunder or under the Notes shall not be paid when due (at
stated maturity, by acceleration or otherwise), interest shall accrue on such
amount from and including such due date to but excluding the date such amount is
paid in full at the Default Rate.

         (b)  Interest on each Variable Rate Loan, Fixed Rate Loan or Money

the account of each of the Banks a facility fee on the daily average amount of
such Bank's Commitment (used and unused) for the period from and including the

is terminated or the Termination Date for such Bank computed at the rate per
annum equal to (i) .15%, if such day falls within a  Level I Period, (ii)
.1875%, if such day falls within a Level II Period, (iii) .25%, if such day

and Moody's Investors Service, Inc. results in the existence of more than one
Level Period, the rate per annum shall be based on the rate set forth in the
higher Level Period.  Accrued facility fees for each Bank shall be payable in
arrears on the last day of each calendar quarter and on the earlier of the date

be deemed to have been made on the next succeeding Banking Day) to the Agent's
account number 900-9-000002 maintained at the Principal Office for the account
of the applicable Lending Office of each Bank; provided that, when a new Loan is
to be made by each Bank on a date the Borrower is to repay any principal of an
outstanding Loan, such Bank shall apply the proceeds thereof to the payment of
the principal to be repaid and only an amount equal to the difference between
the principal to be borrowed and the principal to be repaid shall be made
available by such Bank to the Borrower as provided in Section 2.05 or paid by
the Borrower to such Bank pursuant to this Section 2.13, as the case may be. The
Agent, or any Bank for whose account any such payment is to be made, may (but
shall not be obligated to) debit the amount of any such payment which is not
made by such time to any ordinary deposit account of the Borrower with the Agent
or such Bank, as the case may be, and any Bank so doing shall promptly notify
the Agent. The Borrower shall, at the time of making each payment under this
Agreement or the Notes, specify to the Agent the principal or other amount
payable by the Borrower under this Agreement or the Notes to which such payment
is to be applied (and in the event that it fails to so specify, or if a Default
or Event of Default has occurred and is continuing, the Agent may apply such
payment as it may elect in its sole discretion (subject to Section 10.16)). If
the due date of any payment under this Agreement or the Notes would otherwise
fall on a day which is not a Banking Day, such date shall be extended to the
next succeeding Banking Day and interest shall be payable for any principal so
extended for the period of such extension. Each payment received by the Agent
hereunder or under any Note for the account of a Bank shall be paid promptly to
such Bank, in immediately available funds, for the account of such Bank's
Lending Office.

         Section 2.14.  Extension of Termination Date.  The Termination Date for
any Bank may be extended for a period of one year after the date on which the
Termination Date would otherwise have occurred in accordance with the terms of
this Section 2.14 and the definition of Termination Date.  If the Borrower
wishes to have the Termination Date for any Bank extended, it must give written
notice by registered mail to the Agent and each of the Banks to such effect
within 30 days following the end of the Borrower's fiscal year.  Such notice
shall be in the form attached hereto as Exhibit E.  Such Bank may, in its sole
discretion, refuse to extend its Termination Date by giving written notice to
such effect to the Borrower, the Agent and each of the Banks within 45 days
following receipt by such Bank of the Borrower's request.  Failure by such Bank
to respond during such 45 day time period will constitute an acceptance of the
Borrower's request.  Failure by the Borrower to request an extension shall not
preclude the Borrower from requesting an extension at a later date in accordance
with the provisions of this Section 2.14.


                ARTICLE 3.  YIELD PROTECTION; ILLEGALITY; ETC.

         Section 3.01.  Additional Costs.  (a)  The Borrower shall pay directly
to each Bank from time to time on demand such amounts as such Bank may determine
to be necessary to compensate it for any costs which such Bank determines are
attributable to its making or maintaining any Fixed Rate Loans (or Variable Rate
Loans or Money Market Loans where noted in (ii) below) under this Agreement or
its Notes or its obligation to make any such Loans hereunder, or any reduction
in any amount receivable by such Bank hereunder in respect of any such Loans or
such obligation (such increases in costs and reductions in amounts receivable
being herein called 
 
                                      -16-

<PAGE>
 
"Additional Costs"), resulting from any Regulatory Change which: (i) changes the
basis of taxation of any amounts payable to such Bank under this Agreement or
its Notes in respect of any of such Loans (other than taxes imposed on the
overall net income of such Bank or of its Lending Office for any of such Loans
by the jurisdiction in which such Bank has its principal office or such Lending
Office); (ii) imposes or modifies any minimum capital, capital ratio or similar
requirements relating to any extensions of credit or other assets of, or any
deposits with or other liabilities of, such Bank (including any of such Loans or
any deposits referred to in the definition of "Base Rate" in Section 1.01 and
including any Variable Rate Loans and Money Market Loans); (iii) imposes or
modifies any reserve, special deposit, deposit insurance or assessment relating
to any extensions of credit or other assets of, or any deposits with or other
liabilities of, such Bank (including any of such Loans or any deposits referred
to in the definition of "Base Rate" in Section 1.01); or (iv) imposes any other
condition affecting this Agreement or its Notes (or any of such extensions of
credit or liabilities). Each Bank will notify the Borrower of any event
occurring after the date of this Agreement which will entitle such Bank to
compensation pursuant to this Section 3.01(a) as promptly as practicable after
it obtains knowledge thereof and determines to request such compensation. If any
Bank requests compensation from the Borrower under this Section 3.01(a), or
under Section 3.01(c), the Borrower may, by notice to such Bank (with a copy to
the Agent), suspend the obligation of such Bank to make Loans of the type with
respect to which such compensation is requested (in which case the provisions of
Section 3.04 shall be applicable).

         (b)  Without limiting the effect of the foregoing provisions of this
Section 3.01, in the event that, by reason of any Regulatory Change, any Bank
either (i) incurs Additional Costs based on or measured by the excess above a
specified level of the amount of a category of deposits or other liabilities of
such Bank which includes deposits by reference to which the interest rate on
Eurodollar or CD Loans is determined as provided in this Agreement or a category
of extensions of credit or other assets of such Bank which includes Eurodollar
or CD Loans or (ii) becomes subject to restrictions on the amount of such a
category of liabilities or assets which it may hold, then, if such Bank so
elects by notice to the Borrower (with a copy to the Agent), the obligation of
such Bank to make Loans of such type hereunder shall be suspended until the date
such Regulatory Change ceases to be in effect (in which case the provisions of
Section 3.04 shall be applicable).

         (c)  Without limiting the effect of the foregoing provisions of this
Section 3.01 (but without duplication), the Borrower shall pay directly to each
Bank from time to time on request such amounts as such Bank may determine to be
necessary to compensate such Bank for any costs which it determines are
attributable to the maintenance by it or any of its affiliates pursuant to any
law or regulation of any jurisdiction or any interpretation, directive or
request (whether or not having the force of law and whether in effect on the
date of this Agreement or thereafter) of any court or governmental or monetary
authority of capital in respect of its Loans hereunder or its obligation to make
Loans hereunder (such compensation to include, without limitation, an amount
equal to any reduction in return on assets or equity of such Bank to a level
below that which it could have achieved but for such law, regulation,
interpretation, directive or request).  Each Bank will notify the Borrower if it
is entitled to compensation pursuant to this Section 3.01(c) as promptly as
practicable after it determines to request such compensation.

         (d)  Determinations and allocations by a Bank for purposes of this
Section 3.01 of the effect of any Regulatory Change pursuant to subsections (a)
or (b), or of the effect of capital maintained pursuant to subsection (c), on
its costs of making or maintaining Loans or its obligation to make Loans, or on
amounts receivable by, or the rate of return to, it in respect of Loans or such
obligation, and of the additional amounts required to compensate such Bank under
this Section 3.01, shall be conclusive, provided that such determinations and
allocations are made on a reasonable basis.

         Section 3.02.  Limitation on Types of Loans.  Anything herein to the
contrary notwithstanding, if:

         (a) the Agent determines (which determination shall be conclusive) that
quotations of interest rates for the relevant deposits referred to in the
definition of "Base Rate" in Section 1.01 are not being provided in the relevant
amounts or for the relevant maturities for purposes of determining the rate of
interest for any type of Fixed Rate Loans as provided in this Agreement; or

         (b) the Required Banks determine (which determination shall be
conclusive) and notify the Agent that the relevant rates of interest referred to
in the definition of "Base Rate" in Section 1.01 upon the basis of which the
rate of interest for any type of Fixed Rate Loans is to be determined do not
adequately cover the cost to the Banks of making or maintaining such Loans;

then the Agent shall give the Borrower and each Bank prompt notice thereof, and
so long as such condition remains in effect, the Banks shall be under no
obligation to make Loans of such type.

         Section 3.03.  Illegality.  Notwithstanding any other provision in this
Agreement, in the event that it becomes unlawful for any Bank or its Lending
Office to honor its obligation to make or maintain Eurodollar Loans hereunder,
then such Bank shall promptly notify the Borrower thereof (with a copy to the
Agent) and such Bank's obligation to make or maintain Eurodollar Loans hereunder
shall be suspended until such time as such Bank may again make and maintain such
affected Loans (in which case the provisions of Section 3.04 shall be
applicable).

         Section 3.04.  Certain Variable Rate Loans pursuant to Sections 3.01
and 3.03.  If the obligations of any Bank to make Loans of a particular type
(Loans of such type being herein called "Affected Loans" and such type being
herein called the "Affected Type") shall be suspended pursuant to Section 3.01
or 3.03, all Loans which would otherwise be made by such Bank as Loans of the
Affected Type shall be made instead as Variable Rate Loans and, if an event
referred to in Section 3.01(b) or 3.03 has occurred and such Bank so requests by
notice to the Borrower (with a copy to the Agent), all Affected Loans of such
Bank then outstanding shall be automatically converted into Variable Rate Loans
on the date specified by such Bank in such notice, and, to the extent that
Affected Loans are so made as (or converted into) Variable Rate Loans, all
payments of principal which would otherwise be applied to such Bank's Affected
Loans shall be applied instead to its Variable Rate Loans.

         Section 3.05.  Certain Compensation.  The Borrower shall pay to the
Agent for the account of each Bank, upon the request of such Bank through the
Agent, such amount or amounts 
 
                                      -18-

<PAGE>
 
as shall be sufficient (in the reasonable opinion of such Bank) to compensate it
for any loss, cost or expense which such Bank determines is attributable to:

         (a) any payment of a Fixed Rate Loan made by such Bank on a date other
than the last day of an Interest Period for such Loan (whether by reason of
acceleration or otherwise); or

         (b) any failure by the Borrower to borrow a Fixed Rate Loan to be made
by such Bank on the date specified therefor in the relevant notice under Section
2.05.

         Without limiting the foregoing, such compensation shall include an
amount equal to the excess, if any, of:  (i) the amount of interest which
otherwise would have accrued on the principal amount so paid or not borrowed for
the period from and including the date of such payment or failure to borrow to
but excluding the last day of the Interest Period for such Loan (or, in the case
of a failure to borrow, to but excluding the last day of the Interest Period for
such Loan which would have commenced on the date specified therefor in the
relevant notice) at the applicable rate of interest for such Loan provided for
herein; over (ii) the amount of interest (as reasonably determined by such Bank)
such Bank would have bid in the London interbank market (if such Loan is a
Eurodollar Loan) or the United States secondary certificate of deposit market
(if such Loan is a CD Loan) for Dollar deposits for amounts comparable to such
principal amount and maturities comparable to such period.  A determination of
any Bank as to the amounts payable pursuant to this Section 3.05 shall be
conclusive absent manifest error.

                            ARTICLE 4.  CONDITIONS.

         Section 4.01.  Conditions to Effectiveness.  This Agreement will become

Credit Agreement on the Effective Date).

additional evidence of the indebtedness of the Borrower outstanding under this
Agreement.

         Section 4.02.  Conditions to Borrowing.  The obligations of the Banks

         (ii) no Default or Event of Default has occurred and is continuing, or

the Agent and the Borrower in the Agent's March 7, 1994 letter to the Borrower.

         Section 4.03.  Deemed Representations.  Each notice of a Loan and
acceptance by the Borrower of the proceeds thereof shall constitute a
representation and warranty that the statements contained in Section 4.02(a) are
true and correct both on the date of such notice and, unless the Borrower

Loan.

                  ARTICLE 5.  REPRESENTATIONS AND WARRANTIES.

The Borrower hereby represents and warrants that:

         Section 5.01.  Incorporation, Good Standing and Due Qualification.
Each of the Borrower and its Subsidiaries is duly incorporated, validly existing
and in good standing under the laws of the jurisdiction of its incorporation,
has the corporate power and authority to own its assets and to transact the
business in which it is now engaged or proposed to be engaged, and is duly
qualified as a foreign corporation and in good standing under the laws of each
other jurisdiction in which such qualification is required except to the extent
that its failure to be so qualified would not have a material adverse effect on
the condition (financial or otherwise), properties, assets, business or
operations of the Borrower and its Subsidiaries, taken as a whole.

         Section 5.02.  Corporate Power and Authority; No Conflicts.  The
execution, delivery and performance by the Borrower of the Facility Documents
have been duly authorized by all necessary corporate action and do not and will
not:  (a) require any consent or approval of its stockholders; (b) contravene
its charter or by-laws; (c) violate any provision of, or require any filing,
registration, consent or approval under, any law, rule, regulation (including,
without limitation, Regulation U), order, writ, judgment, injunction, decree,
determination or award presently in effect having applicability to the Borrower
or any of its Subsidiaries or Affiliates; (d) result in a breach of or
constitute a default or require any consent under any indenture or loan or
credit agreement or any other agreement, lease or instrument to which the
Borrower is a party or by which it or its properties may be bound or affected;
(e) result in, or require, the creation or imposition of any Lien, upon or with
respect to any of the properties now owned or hereafter acquired by the
Borrower; or (f) cause the Borrower (or any Subsidiary or Affiliate, as the case
may be) to be in default under any such law, rule, regulation, order, writ,
judgment, injunction, decree, determination or award or any such indenture,
agreement, lease or instrument.
 
                                      -21-

<PAGE>
 
         Section 5.03.  Legally Enforceable Agreements.  Each Facility Document
is, or when delivered under this Agreement will be, a legal, valid and binding
obligation of the Borrower enforceable against the Borrower in accordance with
its terms, except to the extent that such enforcement may be limited by
applicable bankruptcy, insolvency and other similar laws affecting creditors'
rights generally and by general principles of equity.

         Section 5.04.  Litigation.  There are no actions, suits or proceedings
pending or, to the knowledge of the Borrower, threatened, against or affecting
the Borrower or any of its Subsidiaries before any court, governmental agency or
arbitrator, which may, in the aggregate, have a reasonable likelihood of having
a Material Adverse Effect.

         Section 5.05.  Financial Statements.  The consolidated balance sheet of
the Borrower and its Consolidated Subsidiaries as at January 2, 1993, and the
related consolidated statement of earnings and statement of cash flows and
statement of changes in shareholders' equity of the Borrower and its
Consolidated Subsidiaries for the fiscal year then ended, and the accompanying
footnotes, together with the opinion thereon, of Arthur Andersen & Co.,
independent certified public accountants, and the interim consolidated balance
sheet of the Borrower and its Consolidated Subsidiaries as at September 11,
1993, and the related consolidated statement of earnings and statement of cash
flows and changes in shareholders' equity for the 36 week period then ended,
copies of which have been furnished to each of the Banks, are complete and
correct and fairly present the financial condition of the Borrower and its
Consolidated Subsidiaries as at such dates and the results of the operations of
the Borrower and its Consolidated Subsidiaries for the periods covered by such
statements, all in accordance with GAAP consistently applied (subject to year
end adjustments in the case of the interim financial statements).  There are no
liabilities of the Borrower or any of its Consolidated Subsidiaries, fixed or
contingent, which are material but are not reflected in the financial statements
or in the notes thereto or which have not otherwise been disclosed in writing to
the Banks, other than liabilities arising in the ordinary course of business
since September 11, 1993.  No information, exhibit or report furnished by the
Borrower to the Banks in connection with the negotiation of this Agreement
contained any material misstatement of fact or omitted to state a material fact
or any fact necessary to make the statements contained therein not materially
misleading.  Since September 11, 1993, there has been no change in the business,
properties, prospects, condition (financial or otherwise), or results of
operations of the Borrower which could reasonably be expected to have a Material
Adverse Effect.

         Section 5.06.  Ownership and Liens.  Each of the Borrower and its
Restricted Subsidiaries has title to, or valid leasehold interests in, all of
its properties and assets, real and personal, including the properties and
assets, and leasehold interests reflected in the financial statements referred
to in Section 5.05 (other than any properties or assets disposed of in the
ordinary course of business), and none of the properties and assets owned by the
Borrower or any of its Restricted Subsidiaries and none of its leasehold
interests is subject to any Lien, except as disclosed in such financial
statements or as may be permitted hereunder.

         Section 5.07.  Taxes.  Each of the Borrower and its Subsidiaries has
filed all tax returns (federal, state and local) required to be filed and has
paid all taxes, assessments and governmental charges and levies thereon to be
due, including interest and penalties, except to the 
 
                                      -22-

<PAGE>
 
extent that such failure to file returns or pay taxes and other charges would
not have a material adverse effect on the condition (financial or otherwise),
properties, assets, business or operations of the Borrower and its Subsidiaries,
taken as a whole and except for any assessment that the Borrower and its
Subsidiaries are disputing in good faith and have given notice of such dispute
to the Agent (if such assessment is material in amount). The federal income tax
liability of the Borrower and its Subsidiaries has been audited by the Internal
Revenue Service and has been finally determined and satisfied for all taxable
years up to and including the taxable year ended 1992.

         Section 5.08.  ERISA.  Each Plan, and, to the best knowledge of the
Borrower, each Multiemployer Plan, is in compliance in all material respects
with, and has been administered in all material respects in compliance with, the
applicable provisions of ERISA, the Code and any other applicable Federal or
state law, and no event or condition is occurring or exists concerning which the
Borrower would be under an obligation to furnish a report to the Bank in
accordance with Section 6.08(h) hereof.  As of the most recent valuation date
for each Plan, each Plan was "fully funded", which for purposes of this Section
5.08 shall mean that the fair market value of the assets of the Plan is not less
than the present value of the accrued benefits of all participants in the Plan,
computed on a Plan termination basis.  To the best knowledge of the Borrower, no
Plan has ceased being fully funded as of the date these representations are made
with respect to any Loan under this Agreement.

         Section 5.09.  Subsidiaries and Ownership of Stock. Schedule II is a
complete and accurate list of the Subsidiaries of the Borrower, showing the
jurisdiction of incorporation or organization of each Subsidiary and showing the
percentage of the Borrower's ownership of the outstanding stock or other
interest of each such Subsidiary.  Other than as listed on Schedule II, all of
the outstanding capital stock or other interest of each such Subsidiary has been
validly issued, is fully paid and nonassessable and is owned by the Borrower
free and clear of all Liens.

         Section 5.10.  Credit Arrangements.  Schedule III is a complete and
correct list of all Debt and guaranties in respect of which the Borrower or any
of its Restricted Subsidiaries is in any manner directly or contingently
obligated and regarding which the maximum principal or face amount outstanding
and which can be outstanding is $1,000,000 or more; and the maximum principal or
face amounts of the credit in question, outstanding and which can be
outstanding, are correctly stated, and all Liens of any nature given or agreed
to be given as security therefor are correctly described or indicated in such
Schedule.

         Section 5.11.  Operation of Business.  Each of the Borrower and its
Subsidiaries possesses all licenses, permits, franchises, patents, copyrights,
trademarks and trade names, or rights thereto, to conduct its business
substantially as now conducted and as presently proposed to be conducted, except
to the extent that the failure to possess such licenses, permits, franchises,
patents, copyrights, trademarks and trade names, or rights thereto would not
have a material adverse effect on the condition (financial or otherwise),
properties, assets, business or operations of the Borrower or any of its
Subsidiaries, and neither the Borrower nor any of its Subsidiaries is in
violation of any valid rights of others with respect to any of the foregoing.
 
                                      -23-

<PAGE>
 
         Section 5.12.  No Default on Outstanding Judgments or Orders. Each of
the Borrower and its Subsidiaries has satisfied all judgments and neither the
Borrower nor any of its Subsidiaries is in default with respect to any judgment,
writ, injunction, decree, rule or regulation of any court, arbitrator or
federal, state, municipal or other governmental authority, commission, board,
bureau, agency or instrumentality, domestic or foreign, except to the extent
that any of the foregoing would not have material adverse effect on the
condition (financial or otherwise), properties, assets, business or operations
of the Borrower and its Subsidiaries, taken as a whole.

         Section 5.13.  No Defaults on Other Agreements.  Neither the Borrower
nor any of its Subsidiaries is a party to any indenture, loan or credit
agreement or any lease or other agreement or instrument or subject to any
charter or corporate restriction which could have a material adverse effect on
the business, properties, assets, operations or conditions, financial or
otherwise, of the Borrower or any of its Subsidiaries, taken as a whole, or the
ability of the Borrower to carry out its obligations under the Facility
Documents.  Neither the Borrower nor any of its Subsidiaries is in default in
any respect in the performance, observance or fulfillment of any of the
obligations, covenants or conditions contained in any agreement or instrument
which could have material adverse effect on the condition (financial or
otherwise), properties, assets, business or operations of the Borrower and its
Subsidiaries, taken as a whole.

         Section 5.14.  Labor Disputes and Acts of God.  Neither the business
nor the properties of the Borrower or of any of its Subsidiaries are affected by
any fire, explosion, accident, strike, lockout or other labor dispute, drought,
storm, hail, earthquake, embargo, act of God or of the public enemy or other
casualty (whether or not covered by insurance), which could have material
adverse effect on the condition (financial or otherwise), properties, assets,
business or operations of the Borrower and its Subsidiaries, taken as a whole.

         Section 5.15.  Investment Company Act.  Neither the Borrower nor any of
its Restricted Subsidiaries is an "investment company" within the meaning of the
United States Investment Company Act of 1940.

         Section 5.16.  Partner in a Partnership.  Other than as listed in
Schedule IV, as amended by written notice to the Agent from time to time,
neither the Borrower nor any of its Restricted Subsidiaries is a partner in any
partnership.
 
         Section 5.17.  Hazardous Materials.  The Borrower and each of its
Subsidiaries have obtained all permits, licenses and other authorizations which
are required under all Environmental Laws, except to the extent failure to have
any such permit, license or authorization would not have a Material Adverse
Effect.  The Borrower and each of its Subsidiaries are in compliance with the
terms and conditions of all such permits, licenses and authorizations, and are
also in compliance with all other limitations, restrictions, conditions,
standards, prohibitions, requirements, obligations, schedules and timetables
contained in any applicable Environmental Law or in any regulation, code, plan,
order, decree, judgment, injunction, notice or demand letter issued, entered,
promulgated or approved thereunder, except to the extent failure to comply would
not have a Material Adverse Effect.
 
                                      -24-

<PAGE>
 
         In addition, except as set forth in Schedule V hereto and except to the
extent that any of the following in subsections (a) through (e) would not have a
Material Adverse Effect:

         (a)  No notice, notification, demand, request for information,
citation, summons or order has been issued, no complaint has been filed, no
penalty has been assessed and no investigation or review is pending or
threatened by any governmental or other entity with respect to any alleged
failure by the Borrower or any of its Subsidiaries to have any permit, license
or authorization required in connection with the conduct of the business of the
Borrower or any of its Subsidiaries or with respect to any generation,
treatment, storage, recycling, transportation, release or disposal, or any
release as defined in 42 U.S.C. (S) 9601(22) ("Release"), of any substance
regulated under Environmental Laws ("Hazardous Materials") generated by the
Borrower or any of its Subsidiaries.

         (b)  Neither the Borrower nor any of its Subsidiaries has handled any
Hazardous Material, other than as a generator, on any property now or previously
owned or leased by the Borrower or any of its Subsidiaries to an extent that it
has, or may reasonably be expected to have, a material adverse effect on the

interest expense (as stated in the financial statements delivered pursuant to
Section 6.08) of not less than 2.5 to 1.


                        ARTICLE 9.  EVENTS OF DEFAULT.

jurisdiction, whether now or hereafter in effect; or (iv) shall have had any
such petition or application filed or any such proceeding shall have been
commenced, against it, in which an adjudication or appointment is made or order
for relief is entered, or which petition, application or proceeding remains
undismissed for a period of 60 days or more; or (v) by any act or omission shall

vacated, discharged, satisfied or stayed or bonded pending appeal;

         (g) any event or condition shall occur or exist with respect to any
Plan or Multiemployer Plan concerning which the Borrower is under an obligation
to furnish a report to the Bank in accordance with Section 6.08(h) hereof and as

conditions, the Borrower or any ERISA Affiliate has incurred or in the opinion
of the Bank is reasonably likely to incur a liability to a Plan, a Multiemployer
Plan, the PBGC, or a Section 4042 Trustee (or any combination of the foregoing)
which is material in relation to the financial position of the Borrower and its
Subsidiaries, on a consolidated basis; provided, however, that any such amount

the aggregate during any year $5,000,000;
 
                                     -35-

specified in Section 9.01(g) hereof);

         (i)(x) any Forfeiture Proceeding shall have been commenced or the
Borrower shall have given any Bank written notice of the commencement of any

are hereby expressly waived by the Borrower; provided that, in the case of an
Event of Default referred to in Section 9.01(e) or Section 9.01(i)(x) above, the
Commitments shall be immediately terminated, and the Notes, all interest thereon
and all other amounts payable under this Agreement shall be immediately due and
payable without notice, presentment, demand, protest or other formalities of any

          ARTICLE 10.  THE AGENT; RELATIONS AMONG BANKS AND BORROWER.

         Section 10.01.  Appointment, Powers and Immunities of Agent.  Each Bank
hereby irrevocably appoints and authorizes the Agent to act as its agent
hereunder and under any other Facility Document with such powers as are
specifically delegated to the Agent by the terms of this Agreement and any other
Facility Document, together with such other powers as are reasonably incidental
thereto.  The Agent shall have no duties or responsibilities except those
expressly set forth in this Agreement and any other Facility Document, and shall
not by reason of this Agreement be a trustee for any Bank.  The Agent shall not
be responsible to the Banks for any recitals, statements, representations or
warranties made by the Borrower or any officer or official of the Borrower or
any other Person contained in this Agreement or any other Facility Document, or
in any certificate or other document or instrument referred to or provided for
in, or received by any of them under, this Agreement or any other Facility
Document, or for the value, legality, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Facility Document
or any other document or instrument referred to or provided for herein or
therein, for the perfection or priority of any collateral security for the Loans
or for any failure by the Borrower to perform any of its obligations hereunder
or thereunder.  The Agent may employ agents and attorneys-in-fact and shall not
be responsible, except as to money or securities received by it or its
authorized agents, for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable 
 
                                     -36-

<PAGE>


 
care. Neither the Agent nor any of its directors, officers, employees or agents
shall be liable or responsible for any action taken or omitted to be taken by it
or them hereunder or under any other Facility Document or in connection herewith
or therewith, except for its or their own gross negligence or willful
misconduct. The Borrower shall pay any fee agreed to by the Borrower and the
Agent with respect to the Agent's services hereunder.

         Section 10.02.  Reliance by Agent.  The Agent shall be entitled to rely
upon any certification, notice or other communication (including any thereof by
telephone, telex, telegram or cable) believed by it to be genuine and correct
and to have been signed or sent by or on behalf of the proper Person or Persons,
and upon advice and statements of legal counsel, independent accountants and
other experts selected by the Agent.  The Agent may deem and treat each Bank as
the holder of the Loans made by it for all purposes hereof unless and until a
notice of the assignment or transfer thereof satisfactory to the Agent signed by
such Bank shall have been furnished to the Agent but the Agent shall not be
required to deal with any Person who has acquired a participation in any Loan
from a Bank.  As to any matters not expressly provided for by this Agreement or
any other Facility Document, the Agent shall in all cases be fully protected in
acting, or in refraining from acting, hereunder in accordance with instructions
signed by the Required Banks, and such instructions of the Required Banks and
any action taken or failure to act pursuant thereto shall be binding on all of
the Banks and any other holder of all or any portion of any Loan.

         Section 10.03.  Defaults.  The Agent shall not be deemed to have
knowledge of the occurrence of a Default or Event of Default (other than the
non-payment of principal of or interest on the Loans to the extent the same is
required to be paid to the Agent for the account of the Banks) unless the Agent
has received notice from a Bank or the Borrower specifying such Default or Event
of Default and stating that such notice is a "Notice of Default."  In the event
that the Agent receives such a notice of the occurrence of a Default or Event of
Default, the Agent shall give prompt notice thereof to the Banks (and shall give
each Bank prompt notice of each such non-payment).  The Agent shall (subject to
Section 10.08) take such action with respect to such Default or Event of Default
which is continuing as shall be directed by the Required Banks; provided that,
unless and until the Agent shall have received such directions, the Agent may
take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable in the best interest of
the Banks; and provided further that the Agent shall not be required to take any
such action which it determines to be contrary to law.

         Section 10.04.  Rights of Agent as a Bank.  With respect to its
Commitment and the Loans made by it, the Agent in its capacity as a Bank
hereunder shall have the same rights and powers hereunder as any other Bank and
may exercise the same as though it were not acting as the Agent, and the term
"Bank" or "Banks" shall, unless the context otherwise indicates, include the
Agent in its capacity as a Bank.  The Agent and its affiliates may (without
having to account therefor to any Bank) accept deposits from, lend money to (on
a secured or unsecured basis), and generally engage in any kind of banking,
trust or other business with, the Borrower (and any of its affiliates) as if it
were not acting as the Agent, and the Agent may accept fees and other
consideration from the Borrower for services in connection with this Agreement
or otherwise without having to account for the same to the Banks.  Although the
Agent and its affiliates may in the course of such relationships and
relationships with other Persons acquire information about the 
 
                                     -37-

<PAGE>


 
Borrower, its Affiliates and such other Persons, the Agent shall have no duty to
disclose such information to the Banks.

         Section 10.05.  Indemnification of Agent.  The Banks agree to indemnify
the Agent (to the extent not reimbursed under Section 11.04 or under the
applicable provisions of any other Facility Document, but without limiting the
obligations of the Borrower under Section 11.04 or such provisions), ratably in
accordance with the aggregate unpaid principal amount of the Loans made by the
Banks (without giving effect to any participations, in all or any portion of
such Loans, sold by them to any other Person) (or, if no Loans are at the time
outstanding, ratably in accordance with their respective Commitments), for any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind and nature
whatsoever which may be imposed on, incurred by or asserted against the Agent in
any way relating to or arising out of this Agreement, any other Facility
Document or any other documents contemplated by or referred to herein or the
transactions contemplated hereby or thereby (including, without limitation, the
costs and expenses which the Borrower is obligated to pay under Section 11.04 or
under the applicable provisions of any other Facility Document but excluding,
unless a Default or Event of Default has occurred, normal administrative costs
and expenses incident to the performance of its agency duties hereunder) or the
enforcement of any of the terms hereof or thereof or of any such other documents
or instruments; provided that no Bank shall be liable for any of the foregoing
to the extent they arise from the gross negligence or willful misconduct of the
party to be indemnified.

         Section 10.06.  Documents.  The Agent will forward to each Bank,
promptly after the Agent's receipt thereof, a copy of each report, notice or
other document required by this Agreement or any other Facility Document to be
delivered to the Agent for such Bank.

         Section 10.07.  Non-Reliance on Agent and Other Banks.  Each Bank
agrees that it has, independently and without reliance on the Agent or any other
Bank, and based on such documents and information as it has deemed appropriate,
made its own credit analysis of the Borrower and its Subsidiaries and decision
to enter into this Agreement and that it will, independently and without
reliance upon the Agent or any other Bank, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
analysis and decisions in taking or not taking action under this Agreement or
any other Facility Document.  The Agent shall not be required to keep itself
informed as to the performance or observance by the Borrower of this Agreement
or any other Facility Document or any other document referred to or provided for
herein or therein or to inspect the properties or books of the Borrower or any
Subsidiary.  Except for notices, reports and other documents and information
expressly required to be furnished to the Banks by the Agent hereunder, the
Agent shall not have any duty or responsibility to provide any Bank with any
credit or other information concerning the affairs, financial condition or
business of the Borrower or any Subsidiary (or any of their Affiliates) which
may come into the possession of the Agent or any of its affiliates.  The Agent
shall not be required to file this Agreement, any other Facility Document or any
document or instrument referred to herein or therein, for record or give notice
of this Agreement, any other Facility Document or any document or instrument
referred to herein or therein, to anyone.

         Section 10.08.  Failure of Agent to Act.  Except for action expressly
required of the Agent hereunder, the Agent shall in all cases be fully justified
in failing or refusing to act hereunder unless it shall have received further
assurances (which may include cash collateral) of the indemnification
obligations of the Banks under Section 10.05 in respect of any and all liability
and expense which may be incurred by it by reason of taking or continuing to
take any such action.

         Section 10.09.  Resignation of Agent.  Subject to the appointment and
acceptance of a successor Agent as provided below, the Agent may resign (and
shall resign if replaced as a Bank pursuant to Section 11.02) at any time by
giving written notice thereof to the Banks and the Borrower.  Upon any such
resignation, the Required Banks shall have the right to appoint a successor
Agent.  If no successor Agent shall have been so appointed by the Required Banks
and shall have accepted such appointment within 30 days after the retiring
Agent's giving of notice of resignation, then the retiring Agent may, on behalf
of the Banks, appoint a successor Agent.  The Required Banks or the retiring
Agent, as the case may be, shall upon the appointment of a successor Agent
promptly so notify the Borrower and the other Banks.  Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations hereunder.  After any retiring Agent's
resignation hereunder as Agent, the provisions of this Article 10 shall continue
in effect for its benefit in respect of any actions taken or omitted to be taken
by it while it was acting as the Agent.

         Section 10.10.  Amendments Concerning Agency Function.  The Agent shall
not be bound by any waiver, amendment, supplement or modification of this
Agreement or any other Facility Document which affects its duties hereunder or
thereunder unless it shall have given its prior consent thereto.

         Section 10.11.  Liability of Agent.  The Agent shall not have any
liabilities or responsibilities to the Borrower on account of the failure of any
Bank to perform its obligations hereunder or to any Bank on account of the
failure of the Borrower to perform its obligations hereunder or under any other
Facility Document.

         Section 10.12.  Transfer of Agency Function.  Without the consent of
the Borrower or any Bank, the Agent may at any time or from time to time
transfer its functions as Agent hereunder to any of its offices wherever
located, provided that the Agent shall promptly notify the Borrower and the
Banks thereof.

         Section 10.13.  Non-Receipt of Funds by the Agent.  Unless the Agent
shall have been notified by a Bank or the Borrower (either one as appropriate
being the "Payor") prior to the date on which such Bank is to make payment
hereunder to the Agent of the proceeds of a Loan or the Borrower is to make
payment to the Agent, as the case may be (either such payment being a "Required
Payment"), which notice shall be effective upon receipt, that the Payor does not
intend to make the Required Payment to the Agent, the Agent may assume that the
Required Payment has been made and may, in reliance upon such assumption (but
shall not be required to), make the amount thereof available to the intended
recipient on such date and, if the Payor has not in fact 
 
                                     -39-

<PAGE>
 
made the Required Payment to the Agent, the recipient of such payment (and, if
such recipient is the Borrower and the Payor Bank fails to pay the amount
thereof to the Agent forthwith upon demand, the Borrower) shall, on demand,
repay to the Agent the amount made available to it together with interest
thereon for the period from the date such amount was so made available by the
Agent until the date the Agent recovers such amount at a rate per annum equal to
the average daily Federal Funds Rate for such period.

         Section 10.14.  Withholding Taxes.  Each Bank represents that it is
entitled to receive any payments to be made to it hereunder without the
withholding of any tax and will furnish to the Agent such forms, certifications,
statements and other documents as the Agent may request from time to time to
evidence such Bank's exemption from the withholding of any tax imposed by any
jurisdiction or to enable the Agent to comply with any applicable laws or
regulations relating thereto.  Without limiting the effect of the foregoing, if
any Bank is not created or organized under the laws of the United States of
America or any state thereof, in the event that the payment of interest by the
Borrower is treated for U.S. income tax purposes as derived in whole or in part
from sources from within the U.S., such Bank will furnish to the Agent Form 4224
or Form 1001 of the Internal Revenue Service, or such other forms,
certifications, statements or documents, duly executed and completed by such
Bank as evidence of such Bank's exemption from the withholding of U.S. tax with
respect thereto.  The Agent shall not be obligated to make any payments
hereunder to such Bank in respect of any Loan or such Bank's Commitment until
such Bank shall have furnished to the Agent the requested form, certification,
statement or document.

         Section 10.15.  Several Obligations and Rights of Banks.  The failure
of any Bank to make any Loan to be made by it on the date specified therefor
shall not relieve any other Bank of its obligation to make its Loan on such
date, but no Bank shall be responsible for the failure of any other Bank to make
a Loan to be made by such other Bank.  The amounts payable at any time hereunder
to each Bank shall be a separate and independent debt, and each Bank shall be
entitled to protect and enforce its rights arising out of this Agreement, and it
shall not be necessary for any other Bank to be joined as an additional party in
any proceeding for such purpose.

         Section 10.16.  Pro Rata Treatment of Loans, Etc.  Except to the extent
otherwise provided:  (a) each borrowing under Section 2.05 shall be made from
the Banks pro rata according to the amounts of their respective unused
Commitments, (b) each reduction or termination of the amount of the Commitments
under Section 2.08 shall be applied to the Commitments of the Banks, and each
payment of facility fees accruing under Section 2.12 shall be made for the
account of the Banks, pro rata according to the amounts of their respective
Commitments (whether used or unused); and (c) each prepayment and payment of
principal of or interest on Loans of a particular type and a particular Interest
Period shall be made to the Agent for the account of the Banks holding Loans of
such type and Interest Period pro rata in accordance with the respective unpaid
principal amounts of such Loans of such Interest Period held by such Banks.

                          ARTICLE 11.  MISCELLANEOUS.

         Section 11.01.  Amendments and Waivers.  Except as otherwise expressly
provided in this Agreement, any provision of this Agreement may be amended or
modified only by an 
 
                                      -40-
 

<PAGE>
 
instrument in writing signed by the Borrower, the Agent and the Required Banks,
or by the Borrower and the Agent acting with the consent of the Required Banks
and any provision of this Agreement may be waived by the Required Banks or by
the Agent acting with the consent of the Required Banks; provided that no
amendment, modification or waiver shall, unless by an instrument signed by all
of the Banks or by the Agent acting with the consent of all of the Banks: (a)
increase or extend the term, or extend the time or waive any requirement for the
reduction or termination, of the Commitments, (b) extend the date fixed for the
payment of principal of or interest on any Loan or any fee payable hereunder,
(c) reduce the amount of any payment of principal thereof or the rate at which
interest is payable thereon or any fee payable hereunder, (d) alter the terms of
this Section 11.01, (e) amend the definition of the term "Required Banks" or (f)
waive any of the documentary conditions precedent set forth in Section 4.01
hereof and provided, further, that any amendment of Article 10 hereof or any
amendment which increases the obligations of the Agent hereunder shall require
the consent of the Agent. No failure on the part of the Agent or any Bank to
exercise, and no delay in exercising, any right hereunder shall operate as a
waiver thereof or preclude any other or further exercise thereof or the exercise
of any other right. The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

         Section 11.02. Replacement of Banks.  By written notice to the Agent at
least 30 days prior to the date such replacement shall become effective (the
"Replacement Date"), the Borrower may choose to replace any of the Banks party
hereto provided, however, that:

         (a)  Such notice shall specify the Bank or Banks to be replaced, the
replacement bank or banks (the "Replacement Bank") and Replacement Date;

         (b)  The Replacement Date shall not occur during any Money Market
Interest Period with respect to a Money Market Loan made by the Bank being
replaced or during any Fixed Rate Interest Period;

         (c)  As a condition precedent to such replacements the Replacement Bank
shall have executed this Agreement and any additional documents deemed necessary
by the Agent;

         (d)  As a condition precedent to such replacements the Borrower shall
have executed a new Money Market Note and a new Promissory Note for the accounts
of each Replacement Bank and the Bank or Banks being replaced shall have
returned the Money Market Note or Notes and the Promissory Note or Notes to the
Borrower;

         (e)  This Agreement shall be deemed to be amended to replace the Bank
or Banks to be replaced when all of the conditions listed in this Section 11.02
shall have been complied with to the satisfaction of the Agent and no other
amendment this Agreement shall be necessary to effect the replacement; and

         (f)  If the Agent is replaced pursuant to the provisions of this
Section 11.02, then the Agent shall, as soon as it is notified of such
replacement, resign as Agent as set forth in Section 10.09.
 
                                      -41-

<PAGE>
 
         Section 11.03.  Usury.  Anything herein to the contrary
notwithstanding, the obligations of the Borrower under this Agreement and the
Notes shall be subject to the limitation that payments of interest shall not be
required to the extent that receipt thereof would be contrary to provisions of
law applicable to a Bank limiting rates of interest which may be charged or
collected by such Bank.

         Section 11.04.  Expenses.  The Borrower shall reimburse the Agent and
the Banks on demand for all costs, expenses, and charges (including, without
limitation, fees and charges of external legal counsel for the Agent and each
Bank and costs allocated by their respective internal legal departments)
incurred by the Agent or the Banks in connection with the performance or
enforcement of this Agreement or the Notes and incurred by the Banks (other than
the Agent) in connection with preparation, performance or enforcement of this
Agreement or the Notes.  The Borrower agrees to indemnify the Agent and each
Bank and their respective directors, officers, employees and agents from, and
hold each of them harmless against, any and all losses, liabilities, claims,
damages or expenses (each an "Indemnified Liability") incurred by any of them
arising out of or by reason of any investigation or litigation or other
proceedings (including any threatened investigation or litigation or other
proceedings) relating to or arising out of this Agreement or any actual or
proposed use by the Borrower or any Subsidiary of the proceeds of the Loans,
including without limitation, the reasonable fees and disbursements of counsel
incurred in connection with any such investigation or litigation or other
proceedings (but excluding any Indemnified Liability incurred by reason of the
gross negligence or willful misconduct of the Person to be indemnified.  The
Borrower agrees that any Indemnified Liability will be promptly paid to the
Person to be indemnified upon the written demand of such Person.

         Section 11.05.  Survival.  The obligations of the Borrower under
Sections 3.01, 3.05 and 11.04 shall survive the repayment of the Loans and the
termination of the Commitments.

         Section 11.06.  Assignment; Participation.  This Agreement shall be
binding upon, and shall inure to the benefit of, the Borrower, the Agent, the
Banks and their respective successors and assigns, except that the Borrower may
not assign or transfer its rights or obligations hereunder.  Each Bank may
assign, with the consent of the Borrower (which shall not be unreasonably
withheld), or sell participations in, all or any part of any Loan to another
bank or other entity, in which event (a) in the case of an assignment, upon
notice thereof by the Bank to the Borrower with a copy to the Agent, the
assignee shall have, to the extent of such assignment (unless otherwise provided
therein), the same rights, benefits and obligations as it would have if it were
a Bank hereunder; and (b) in the case of a participation, the participant shall
have no rights under the Facility Documents and all amounts payable by the
Borrower under Article 3 shall be determined as if such Bank had not sold such
participation.  The agreement executed by such Bank in favor of the participant
shall not give the participant the right to require such Bank to take or omit to
take any action hereunder except action directly relating to (i) the extension
of a payment date with respect to any portion of the principal of or interest on
any amount outstanding hereunder allocated to such participant, (ii) the
reduction of the principal amount outstanding hereunder or (iii) the reduction
of the rate of interest payable on such amount or any amount of fees payable
hereunder to a rate or amount, as the case may be, below that which the
participant is entitled to receive under its agreement with such Bank.  Such
Bank may furnish any information concerning the Borrower in the 
 
                                      -42-

<PAGE>
 
possession of such Bank from time to time to assignees and participants
(including prospective assignees and participants); provided that such Bank
shall require any such prospective assignee or such participant (prospective or
otherwise) to agree in writing to maintain the confidentiality of such
information. Notwithstanding any other language in this Agreement, any Bank may
at any time assign all or any portion of its rights under this Agreement and the
Notes to a Federal Reserve Bank as collateral in accordance with Regulation A of
the Board of Governors of the Federal Reserve System and the applicable
operating circular of such Federal Reserve Bank. In connection with any

administrative fee for processing such assignment in the amount of $3,000.

         Section 11.07.  Notices.  Unless the party to be notified otherwise
notifies the other party in writing as provided in this Section, and except as
otherwise provided in this Agreement and except for notices given pursuant to
Section 2.02 hereof, which shall be given by telephone, confirmed in writing by
telex or telecopy by the close of business on the day the notice is given,

         Section 11.08.  Setoff.  The Borrower agrees that, in addition to (and
without limitation of) any right of setoff, banker's lien or counterclaim a Bank

balances (general or special, time or demand, provisional or final) held by it
for the account of the Borrower at any of such Bank's offices, in Dollars or in
any other currency, against any amount payable by the Borrower to such Bank
under this Agreement or such Bank's Note which is not paid when due (regardless
of whether such balances are then due to the Borrower), in which case it shall
promptly notify the Borrower and the Agent thereof; provided that such Bank's
failure to give such notice shall not affect the validity thereof. Payments by
the Borrower hereunder shall be made without setoff or counterclaim.

         SECTION 11.09.  JURISDICTION; IMMUNITIES.  (a) THE BORROWER HEREBY
IRREVOCABLY SUBMITS TO THE JURISDICTION OF ANY NEW YORK STATE OR UNITED STATES

BE HEARD AND DETERMINED IN SUCH NEW YORK STATE OR FEDERAL COURT.  THE BORROWER
IRREVOCABLY CONSENTS TO THE SERVICE OF ANY AND ALL PROCESS IN ANY SUCH ACTION OR
PROCEEDING BY THE MAILING OF COPIES OF SUCH PROCESS TO THE BORROWER AT ITS
ADDRESS SPECIFIED IN SECTION 11.07.  THE BORROWER AGREES THAT A FINAL JUDGMENT
IN ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN
OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY
LAW.  THE BORROWER FURTHER WAIVES ANY OBJECTION TO

<PAGE>
 
VENUE IN SUCH STATE AND ANY OBJECTION TO AN ACTION OR PROCEEDING IN SUCH STATE

ACTION OR PROCEEDING BROUGHT AGAINST THE AGENT SHALL BE BROUGHT ONLY IN NEW YORK
STATE OR UNITED STATES FEDERAL COURT SITTING IN NEW YORK COUNTY. THE BORROWER
WAIVES ANY RIGHT IT MAY HAVE TO JURY TRIAL.

         (b)  Nothing in this Section 11.09 shall affect the right of the Agent
or any Bank to serve legal process in any other manner permitted by law or
affect the right of the Agent or any Bank to bring any action or proceeding
against the Borrower or its property in the courts of any other jurisdictions.

         (c)  To the extent that the Borrower has or hereafter may acquire any
immunity from jurisdiction of any court or from any legal process (whether from
service or notice, attachment prior to judgment, attachment in aid of execution,
execution or otherwise) with respect to itself or its property, the Borrower
hereby irrevocably waives such immunity in respect of its obligations under this
Agreement and the Notes.

         Section 11.10.  Table of Contents; Headings.  Any table of contents and
the headings and captions hereunder are for convenience only and shall not
affect the interpretation or construction of this Agreement.

         Section 11.11.  Severability.  The provisions of this Agreement are
intended to be severable.  If for any reason any provision of this Agreement
shall be held invalid or unenforceable in whole or in part in any jurisdiction,
such provision shall, as to such jurisdiction, be ineffective to the extent of
such invalidity or unenforceability without in any manner affecting the validity
or enforceability thereof in any other jurisdiction or the remaining provisions
hereof in any jurisdiction.

         Section 11.12.  Counterparts.  This Agreement may be executed in any
number of counterparts, all of which taken together shall constitute one and the
same instrument, and any party hereto may execute this Agreement by signing any
such counterpart.

         Section 11.13.  Integration.  The Facility Documents set forth the
entire agreement among the parties hereto relating to the transactions
contemplated thereby and supersede any prior oral or written statements or
agreements with respect to such transactions.

         SECTION 11.14.  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY,
AND INTERPRETED AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW
YORK.

         Section 11.15.  Treatment of Certain Information.  The Borrower (a)
acknowledges that services may be offered or provided to it (in connection with
this Agreement or otherwise) by each Bank or by one or more of their respective

be shared among such Bank and such subsidiaries and affiliates. This Section
11.15 shall survive the repayment of the Loans and the termination of the

                    (Letterhead of counsel to the Borrower)


                                    [Date]



The Chase Manhattan Bank, N.A.
1 Chase Manhattan Plaza
New York, New York 10081

[other Banks]

Ladies and Gentlemen:

         We have acted as counsel to Safety-Kleen Corp. (the "Borrower") in
connection with the execution and delivery of that certain Amended and Restated
Credit Agreement (the "Credit Agreement") dated as of March 25, 1994 among the
Borrower, the Banks signatory thereto and The Chase Manhattan Bank, N.A. as
Agent.  Except as otherwise defined herein, all terms used herein and defined in
the Credit Agreement or any agreement delivered thereunder shall have the
meanings assigned to them therein.

         In connection with this opinion, we have examined executed copies of
the Facility Documents and such other documents, records, agreements and
certificates as we have deemed appropriate.  We have also reviewed such matters
of law as we have considered relevant for the purpose of this opinion.

         Based upon the foregoing, we are of the opinion that:

         1.  Each of the Borrower and its Subsidiaries is a corporation duly
incorporated, validly existing and in good standing under the laws of the
jurisdiction of its incorporation, has the corporate power and authority to own
its assets and to transact the business in which it is now engaged or proposed
to be engaged, and is duly qualified as a foreign corporation and in good
standing under the laws of each other jurisdiction in which such qualification
is required except to the extent that its failure to be so qualified would not
have a material adverse effect on the condition (financial or otherwise),
properties, assets, business or operations of the Borrower and its Subsidiaries,
taken as a whole.

         2.  The execution, delivery and performance by the Borrower of the
Facility Documents have been duly authorized by all necessary corporate action
and do not and will not:  (a) require any consent or approval of its
stockholders; (b) contravene its charter or by-laws; (c) violate 
 
<PAGE>
 
any provision of, or require any filing, registration, consent or approval
under, any law, rule, regulation (including without limitation, Regulation U),
order, writ, judgment, injunction, decree, determination or award presently in
effect having applicability to the Borrower or any of its Subsidiaries or
affiliates; (d) result in a breach of or constitute a default or require any
consent under any indenture or loan or credit agreement or any other agreement,
lease or instrument to which the Borrower is a party or by which it or its
properties may be bound or affected; (e) result in, or require, the creation or
imposition of any Lien, upon or with respect to any of the properties now owned
or hereafter acquired by the Borrower; or (f) cause the Borrower (or any
Subsidiary or affiliate, as the case may be) to be in default under any such
law, rule, regulation, order, writ, judgment, injunction, decree, determination
or award or any such indenture, agreement, lease or instrument.

         3.  Each Facility Document is, or when delivered under the Credit
Agreement will be, a legal, valid and binding obligation of the Borrower,
enforceable against the Borrower in accordance with its terms, except to the
extent that such enforcement may be limited by applicable bankruptcy, insolvency
and other similar laws affecting creditors' rights generally.

         4.  To the best of our knowledge (after due inquiry), there are no
pending or threatened actions, suits or proceedings against or affecting the
Borrower or any of its Subsidiaries before any court, governmental agency or
arbitrator, which may, in the aggregate, have a reasonable likelihood of having
a materially adverse effect on the financial condition of the Borrower and the
Subsidiaries, taken as a whole, or on the ability of the Borrower to perform its
obligations under the Facility Documents.

 

                               Very truly yours,

  In 1987, the Company made two long-term strategic acquisitions to enter the
North American Oil Recovery Service and expand its ability to service large and
small industrial customers' fluid waste disposal needs. Subsequent to these
acquisitions, substantial capital and other infrastructure investments were made
to accommodate future anticipated growth. In 1990, the Company made the
strategic decision to develop and expand its business in Western Europe on a
direct basis. The implementation of this strategy has required investments in
the acquisition of its joint venture partners' interests in operations in
several countries, acquisition of other related businesses and accompanying
infrastructure investments.

Summary of 1992, 1993 and 1994 Financial Results. 

  In 1992 and 1993, the Company's net earnings before restructuring and special
charges declined 12% and 24%, respectively. However, in 1994, the Company's net
earnings increased 45% over 1993 net earnings before restructuring and special
charges largely as a result of the restructuring plan and change in accounting
estimate for remediation costs implemented at the end of 1993, which are more
fully described below.

  The cost increases underlying the 1992 and 1993 earnings declines were largely
the result of strategic and infrastructure investments mentioned above. These
investments were made primarily in anticipation of future long-term growth,
which has been realized more slowly than originally anticipated. The Company
also experienced increased environmental compliance costs.

  The Company's 1992 earnings were also adversely affected by costly regulatory
problems encountered at its Puerto Rico operations. Pre-tax charges totalling
approximately $11.4 million ($7.3 million after tax) were taken in 1992 to
record the estimated costs of reducing excess storage of hazardous waste fluids
to permitted levels, providing for possible environmental remediation of waste
water discharges and paying penalties related thereto. Since this time, the
Company has incurred substantially higher costs to process waste-derived fuel
collected from its Puerto Rico customers. These higher costs are due primarily
to the local third-party cement kiln outlet's inability to burn waste-derived
fuels on a sustained basis. This has resulted in additional costs to transport
waste-derived fuels in Puerto Rico to the U.S. mainland for processing.

  The Company believes that lower demand for its services has been the primary
cause of flat revenues from 1992 through 1994. A number of factors have
contributed to this lower demand, including waste and cost minimization efforts
by customers, sluggish economies in North America and Europe in 1993 and slower
than expected development of the Company's European operations. In addition,
1994 revenues were impacted by the elimination of certain product and service
lines, as the result of the restructuring plan implemented in the fourth interim
period of 1993. 

Cyclonic Parts Cleaner Service.

  In order to address the waste minimization concerns of its customers, the
Company began converting its existing Model 16 and 30 red sink-on-a-drum parts
cleaners in the United States to a new cyclonic parts cleaner service in 1993.
The new service employs a premium non-hazardous solvent and a patented cyclonic
separation technology that continuously removes dirt particles from the solvent
during use. As a result, the solvent stays cleaner longer,

extending the life of the solvent and reducing the number of annual services
required. With the new cyclonic parts cleaner service, customers need service
less frequently and generate less waste on an annual basis, which reduces the
cost of the Parts Cleaner Service to Safety-Kleen and also provides customers
with the potential to reduce their cost.

  At December 31, 1994, the Company had placed approximately 103,000 cyclonic
machines at customer locations, and there were approximately 155,000 red Model
16 and 30 parts cleaners remaining in service with customers in the United
States.  These 155,000 machines represent approximately 42% of the total
installed base of Company-owned parts cleaners in the United States.  The
Company expects to convert a large portion of the remaining Model 16 and 30
parts cleaner machines to the cyclonic parts cleaner in 1995 and 1996.

  The Company believes the new cyclonic service will reduce the turnover rate
of its existing parts cleaner base and result in faster penetration of the
market. The Company also anticipates the gross profit margin of its parts
cleaner service will improve as a result of a price increase that was
instituted on the red machine service in October 1994, and gains in
efficiencies associated with a growing base of cyclonic service customers.  

  In conjunction with the conversion of parts cleaners to new technology and a
comprehensive review of its operations, the Company adopted a restructuring plan
in the fourth interim period of 1993. The restructuring plan is more fully
described below in "Results of Operations" under the subheading "Restructuring
and Special Charges".

  In 1994, the Company developed and test marketed a proprietary filtration
device which can be added to larger Safety-Kleen machines and a substantial
portion of customer-owned parts cleaners. The Company believes this filtration
device should provide these customers with the opportunity to receive waste
minimization and cost reduction benefits similar to the cyclonic parts cleaner
service.

OTHER TRENDS, EVENTS AND UNCERTAINTIES

  While the Company can benefit from increased governmental regulation, as a
leading environmental services company, it is also the focus of regulatory
scrutiny.  The Company's goal is to fully comply with all regulations and thus
avoid any fines or penalties, and the Company has committed significant human
and capital resources to the pursuit of this goal.  Nonetheless, given its
extensive operations, the technical aspects of the regulations, and the
varying interpretations of the requirements from jurisdiction to jurisdiction,
the Company may incur fines and penalties as a natural consequence of its
business operations. While the Company does not anticipate that the amount of
fines and penalties will have a material adverse impact on its financial
condition, many environmental laws are written and enforced in a way in which
the potential liability can be large, and it is always possible that the
Company's actual liability in any particular case will prove to be larger than
anticipated by the Company. It is also possible that expenses incurred in any
particular reporting period for remediation costs or for fines, penalties or
judgments, could have a material impact on the Company's results of operations
for that period. The Company paid approximately $4 million, $1 million and $3
million in 1994, 1993 and 1992, respectively, for environmental fines, penalties
and forfeitures.

  State and local authorities are increasingly adopting legislation and
regulations which impose stricter operating and performance standards and
increased taxes, assessments and fees upon the generators, transporters and
handlers of hazardous and non-hazardous waste.  The Company may or may not be
able to pass on the costs associated with such legislation and regulations to
its customers through price increases.

EFFECTS OF PETROLEUM PRICE CHANGES

  Through its Oil Recovery operations, the Company re-refines and markets
petroleum based products at prices positively correlated to crude oil prices
over the long-term.  The Company's various service operations (such as its
Parts Cleaner Service) also consume petroleum based products, the cost of which
are positively correlated to crude oil prices over the long-term. Consequently,
any meaningful increase or decrease in crude oil prices will have both a
positive and negative effect on earnings. Generally, the Company's earnings are
positively affected by higher crude oil prices and are negatively affected by
lower crude oil prices. The speed at which the Company is able to raise prices
on its services and products is restricted somewhat by committed price
contracts.

LIQUIDITY AND CAPITAL RESOURCES

  Capital spending in 1994, 1993 and 1992 for additions of equipment at
customers and property, excluding business acquisitions, totaled $88 million,
$96 million and $143 million, respectively. These capital expenditures were
financed primarily by cash from operations. Long-term debt decreased $5 million
and $12 million in 1994 and 1993, respectively.

  The Company expects its capital expenditures for equipment at customers and
property additions for the full year 1995 will be less than $90 million. The
Company expects to be able to finance these expenditures entirely through
internally generated funds. As more fully described in Note 5 to the
Consolidated Financial Statements, 

                                                                           21

the Company and its subsidiaries have lines of credit aggregating approximately
$340 million. As of December 31, 1994, total borrowings under these lines were
$179 million. The Company does expect to lease equipment and property to a
greater extent than it has in the recent past.

  Subsequent to year-end 1994, the Company entered into a note purchase
agreement with two insurance companies, under which the Company borrowed $50
million at a fixed interest rate of 8.05% for 3 years expiring in January,
1998. Proceeds from the note were used to repay existing bank borrowings.

  A portion of the Company's capital expenditures are related to compliance with
environmental laws and regulations. The Company estimates capital spending of
approximately $7 million in 1995 and $14 million in the years 1996 through 1999
in order to comply with current environmental laws and regulations in connection
with the Company's existing business.

</TABLE> 

North American Automotive/Retail Repair Services. 

  Lack of sales from discontinued allied products accounted for $6.4 million
of the Company's North American Automotive/Retail Repair Services 1994 revenue
decline.  Most of the remaining $4.5 million revenue decline was due to a 2%
decline in parts cleaner service volume caused primarily by a lengthening of
the average time interval between services.  The average service charge was
flat with 1993.  The 1993 revenue decline was caused by an 8% decline in
service volumes, partially offset by service charges which were, on average, 7%
higher in 1993 than 1992.  The 1993 service volume decline is primarily a
result of lengthening in the average time interval between services and fewer
parts cleaner machines in service.

North American Industrial Services. 

  Revenue from the Company's North American Industrial Services includes Fluid
Recovery Service revenue of $109.1 million in 1994, $96.8 million in 1993, and
$85.0 million in 1992. The 13% increase in Fluid Recovery Service revenue in
1994 was due to higher volumes. A 26% increase in the number of drums collected
was partially offset by an 8% decline in the average revenue per drum which can
be attributed to drum quantity and regional discounts offered in 1994. The 14%
revenue increase in 1993 was due almost entirely to a 12% increase in the number
of drums collected. Average revenue per drum increased by 1% in 1993.

  The North American Industrial Parts Cleaner Service accounts for the remaining
revenue of $113.0 million in 1994, $116.1 million in 1993 and $112.2 million in
1992. The lower revenue experienced in 1994 was due almost entirely to the lack
of sales from discontinued allied products. The favorable impact of a 5%
increase in the average parts cleaner service charge in 1994 was offset by a 6%
decline in parts cleaner service volume. The Parts Cleaner Service volume
decline in 1994 was primarily due to a lengthening in the average time interval
between services. Increased prices accounted for most of the revenue growth in
1993. Parts cleaner service volumes declined 5% in 1993 primarily as a result of
lengthening in the average time interval between services, partially offsetting
the favorable effect of increased prices. 

North American Oil Recovery Services.

  The increase in revenue experienced in 1994 from the North American Oil
Recovery Services was primarily due to a 16% increase in the volume of
lubricating oil sales, which was partially offset by 7% lower average lube oil
sales prices. The 1993 revenue decline was primarily the result of lower prices
realized in 1993 for sales of lubricating oil and collection of used oil. The
negative effect of lower prices in 1993 was partially offset by a shift in sales
mix from lower value industrial fuel to higher value re-refined lubricating oil.
This shift was made possible by 12% and 50% capacity expansions at the Company's
East Chicago, Indiana re-refinery in 1993 and 1992, respectively.

North American Other Service Areas.  

  Revenue from Other Service Areas decreased in 1994 due primarily to the lack
of sales from discontinued allied products and the planned lower volume of
Envirosystems revenue as a result of

                                                                        [LOGO]
 
the reduction of toll recycling capacity completed during the restructuring. The
revenue decline in 1993 from 1992 was due primarily to lower revenue from the
Company's Envirosystems operations caused mainly by lower volumes and product
mix. 

Europe.

  A strengthening of European currencies against the U.S. dollar increased
revenue by approximately $1.4 million in 1994. Exclusive of exchange rate
effects, revenues in Europe increased approximately 6% due to higher volumes and
prices throughout most of the European operations.

  The European revenue decline in 1993 was attributable to weaker European
currencies, which lowered 1993 revenues by approximately $9.0 million. Exclusive
of the change in exchange rates, European revenues increased nearly 9%.
Approximately 50% of this 1993 revenue increase is attributable to the
acquisition of the Company's joint venture partner's 50% interest in the Spanish
joint venture completed in September, 1992. The remaining 1993 increase in
European revenues resulted from increased volumes and prices.

Operating Costs and Expenses.

</TABLE> 

North American Automotive/Retail Repair Services.  

  The North American Automotive/Retail Repair Services gross margin improved in
1994 from 1993 primarily due to the Company's lower cost structure which
resulted from its restructuring plan and the change in accounting estimate for
remediation costs implemented in the fourth interim period of 1993. The gross
margin decline experienced in 1993 resulted primarily from expansion costs
incurred in anticipation of growth in demand for the Company's services that was
not fully realized and higher costs for environmental compliance in its branch,
distribution and recycling networks. These higher fixed expansion and
environmental compliance costs affected all of the North American Services
except for Oil Recovery Services, in varying degrees. These costs had a
particularly adverse impact on the Automotive/Retail Repair Service gross margin
because of the decline in revenue.

North American Industrial Services.  

  Gross margins for the Company's North American Industrial Services remained
unchanged from 1992 through 1994. The favorable benefits realized from the lower
cost structure in 1994 as a result of the restructuring plan and change in
accounting estimate were offset by lower parts cleaner service volume and lower
average revenue per drum in the Fluid Recovery Service. In 1993, the effect of
higher average prices charged on the Industrial Parts Cleaner Service was offset
by the lower volume of services performed.

North American Oil Recovery Services. 

  The improvement in the Oil Recovery Services 1994 gross profit margin can be
attributed to a lower cost structure in the automotive used oil collection
business resulting from the Company's restructuring plan that was implemented in
1993, and certain plant processing improvements. The Company implemented a price
increase in the Oil Collection Service in the second quarter of 1994. The 1993
decline in gross profitability of the Company's Oil Recovery Services was
primarily due to lower prices realized in 1993 for sales of lubricating oil and
the collection of used oil.

North American Other Service Areas.  

  The increase in the North American Other Service Areas gross profit margin
experienced in 1994 resulted primarily from the elimination of the lower margin
allied product businesses contemplated by the Company's restructuring plan. The
1993 improvement in North American Other Service Areas gross profitability is
primarily due to a $10.5 million reduction in the gross loss of the Company's
Puerto Rico Envirosystems operations. This improvement in the Puerto Rico
operations is attributable to charges associated with the 1992 regulatory
problems discussed earlier. A $2.0 million dispute settlement with the State of
Kentucky regarding hazardous waste fees and penalties for alleged violations
also reduced gross profits in 1992. A $2.2 million increase in alternative waste
fuel processing costs in the Company's U.S. Envirosystems operations adversely
affected North American Other Service Areas gross profit margin in 1993.

Europe. 

  The increase in Europe's 1994 gross profit margin is mainly attributable to
work force reductions, and elimination of lower 

                                                                            23

margin businesses in connection with the Company's restructuring plan. The 1993
decline in Europe's gross profit margin was due primarily to more rapid revenue
growth in markets which have lower gross margins.

Selling and Administrative Expenses. 

  Selling and administrative expenses decreased 5% in 1994, primarily due to
work force reductions implemented as part of the Company's restructuring plan.
Selling and administrative expenses increased 5% in 1993, primarily due to
additional employees and employee expenses and increases in compensation and
benefits.

Restructuring and Special Charges. 

  During the fourth interim period of 1993, the Company adopted a restructuring
plan based on conversion of its Parts Cleaner Service to new technology and
other strategic actions to better focus the Company on its core environmental
services, reduce its cost structure and improve the value of its services to its
customers. In conjunction with the adoption of this plan, the Company recorded a
restructuring charge of $179 million ($106 million after-tax or $1.84 per
share). The pre-tax restructuring charge of $179 million included $93 million of
asset write-downs and $86 million of other restructuring charges. The after-tax
restructuring charge of $106 million included an estimated $34 million of costs
requiring cash outflows and $72 million of non-cash items. During 1994, the
Company's restructuring activities proceeded substantially in accordance with
the original plan. The Company's restructure reserves declined $25.2 million in
1994 from $84.2 million to $59.0 million. The Company incurred $20 million of
after-tax cash flows in 1994. In 1994, the Company also received a $10.8 million
refund of estimated tax payments made in 1993. The Company still expects to
incur an estimated $13 million of after tax cash flows associated with the
restructuring in 1995 and beyond.

  As part of the restructuring plan, the Company provided for the write-down
of the cost of parts cleaner machines expected to be replaced with the new
cyclonic parts cleaners, as well as the cost of converting customers to the new
service.

  The Company anticipated that converting a large portion of its existing parts
cleaners to the new cyclonic technology would result in less spent solvent being
collected from the Company's parts cleaner service. Accordingly, the Company
decided to convert many of its branch permitted hazardous waste storage
facilities to transfer locations, thereby eliminating the need for permits
required under the Resource Conservation and Recovery Act (RCRA) and reducing
unnecessary operating costs driven by RCRA-imposed requirements. The non-cash
restructuring charge included the write-off of the capitalized cost of the
permits at these affected facilities. The restructuring charge also included a
write-down of recycling capacity because the collection of less spent solvent
would reduce the amount of solvent recycling capacity required.

  Other elements of the restructuring plan included: (i) a work force reduction
of approximately 375 jobs and payment of severance benefits; (ii) a write-down
of inventories and other assets for discontinuing certain minor business
activities, including the sale of allied products; and (iii) accrual of costs
and asset write-downs related to the curtailment or sale of certain operations.

  In addition to the restructuring charge, the Company recorded a $50 million
special charge ($30 million after-tax or $.52 per share) representing a change
in estimate for remediation costs. These additional remediation costs were
estimated prior to conducting detailed individual site investigations to
ascertain the existence and extent of contamination, and were related to all
operating and previously closed sites. The Company expects the expenditures for
these remediation costs will occur over several years. Primarily as a result of
the special charge, the Company's expenses for environmental remediation
declined $11.6 million in 1994 compared to 1993. Total accrued environmental
liabilities declined from $66.5 million at the end of 1993 to $49.7 million at
the end of 1994 due to substantial remediation activities in 1994.

  The Company experienced an estimated net earnings benefit of $16 million in
1994 directly attributable to cost reductions and other actions resulting from
the restructuring plan and the special charge in 1993.

Interest Income. 

  The $135,000 and $480,000 declines in interest income in 1994 and 1993,
respectively, are due primarily to a lower average investment balance in 1994
and lower interest rates in 1993.

Interest Expense. 

  Interest expense increased $4.1 million in 1994 due mainly to increased
interest rates and lower capitalized interest. Interest expense excludes $2.4,
$4.5 and $5.2 million of interest capitalized during 1994, 1993 and 1992,
respectively. Interest expense decreased $1.5 million in 1993 due to lower
rates. The impact of the interest rate swaps executed in the United States and
Germany in 1992 and 1993 and more fully explained in Note 5 to the Consolidated
Financial Statements resulted in interest expense savings of $1.8, $3.6 and $3.2
million in 1994, 1993 and 1992, respectively.

Income Taxes. 

  The effective income tax rate was 41% in 1994, 40% in 1993 and 39% in 1992. 
The increase in the effective tax rate in 1994 is primarily due to an increase
in non-deductible expenses.  The increase in the effective tax rate in 1993 is
primarily due to an increase in the U.S. statutory income tax rate.

Accounting Changes. 

  The Company adopted Statement of Financial Accounting Standards (SFAS) No. 112
on accounting for post-employment benefits in fiscal year 1993. The effect of
adopting this accounting change was not material. The Company adopted SFAS No.
106 on accounting for post-retirement benefits and SFAS No. 109 on accounting
for income taxes in fiscal year 1992. The cumulative prior years' effect of SFAS
No. 106 reduced net earnings by $2.9 million, or five cents per share increase
in 1992. The cumulative prior years' effect of SFAS No. 109 increased net
earnings by $3.2 million, or six cents per share in 1992. The effects of
adopting SFAS Nos. 106 and 109 are more fully discussed in Notes 7 and 8 to the
Consolidated Financial Statements.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Board of Directors and Shareholders of Safety-Kleen Corp.:

  We have audited the accompanying consolidated balance sheets of Safety-Kleen
Corp. (a Wisconsin corporation) and Subsidiaries as of December 31, 1994 and
January 1, 1994, and the related consolidated statements of operations,
shareholders' equity and cash flows for each of the three fiscal years in the
period ended December 31, 1994. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

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

  In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Safety-Kleen Corp. and
Subsidiaries as of December 31, 1994 and January 1, 1994, and the results of
their operations and their cash flows for each of the three fiscal years in the
period ended December 31, 1994, in conformity with generally accepted accounting
principles.

  As discussed in notes 7 and 8 to the consolidated financial statements,
effective December 29, 1991, the Company changed its methods of accounting for
post-retirement benefits other than pensions and income taxes.

                                             Safety-Kleen Corp. and Subsidiaries
 

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

  The Consolidated Financial Statements include the accounts of the Company
and its subsidiaries after elimination of all significant intercompany balances
and transactions.  The Company's fiscal year ends on the Saturday closest to
December 31.  Fiscal year 1992 has fifty-three weeks while fiscal years 1994
and 1993 have fifty-two weeks.

Equipment at Customers and Related Depreciation

  Equipment at customers is capitalized at manufactured or purchased cost.
Depreciation is computed using the straight-line method over a period of 3 to 13
years, commencing when the units are placed in service.

Property and Related Depreciation

  Land, buildings and improvements, leasehold improvements, machinery and
equipment, and autos and trucks are capitalized at cost. Items of an ordinary
repair or maintenance nature are charged directly to operating expense.
Improvement costs are capitalized and charged to operations over the shorter of
the improvement life or the related asset life. Depreciation is computed
principally using the straight-line method over the estimated useful lives as
follows: Buildings and improvements 5 to 40 years; machinery and equipment 2 to
20 years; autos and trucks 4 to 10 years; and leasehold improvements over the
shorter of the 5 to 10 years, or remaining term of the lease.

Intangible Assets and Related Amortization

  Goodwill consists primarily of the cost of acquired businesses in excess of
market value of net assets acquired.  Goodwill is being amortized on a
straight-line basis over forty years. Subsequent to its acquisition, the
Company continually evaluates whether later events and circumstances have
occurred that indicate the remaining estimated useful life of goodwill may
warrant revision or that the remaining balance of goodwill may not be
recoverable. When factors indicate that goodwill should be evaluated for
possible impairment, the Company uses an estimate of the related business
segment's undiscounted net income over the remaining life of the goodwill in
measuring whether the goodwill is recoverable.

  Other intangible assets consist primarily of costs to obtain customers,
regulatory operating permits and computer software. Amortization of other
intangible assets is computed using the straight-line method over the expected
life of the related intangible asset, which principally ranges from 3 years to
15 years.

Environmental Remediation Costs and Liabilities

  The Company reviews the adequacy of its liability for environmental
remediation on a periodic basis and records adjustments to costs and
liabilities accordingly. In 1993 the Company recorded a $50 million pre-tax
charge for a change in estimate for remediation costs relating to all operating
and previously-closed sites prior to conducting detailed individual site
investigations to ascertain the existence and extent of contamination.  

Earnings (Loss) Per Share

  Earnings (loss) per share amounts are based on the average shares of common
stock outstanding during each year and common stock equivalents of dilutive
stock options.

Statement of Cash Flows

  Short-term investments with original maturities of 90 days or less are
considered to be cash equivalents for purposes of the Consolidated Statements of
Cash Flows and Consolidated Balance Sheets. Cash flows associated with items
intended as hedges of identifiable transactions are classified in the same
categories as the cash flows of the items being hedged.

2. ACQUISITIONS

  All acquisitions made during the three fiscal years ended December 31, 1994
were accounted for using the purchase method and, accordingly, their operating
results have been included in the Company's Consolidated Statements of
Operations only since the respective dates of acquisition. The acquisitions were
not material either individually or in the aggregate.

3. SEGMENT INFORMATION

  The Company and its subsidiaries operate in the United States, the
Commonwealth of Puerto Rico, Canada and the seven European countries, consisting
of the United Kingdom, the Republic of Ireland, France, Belgium, Italy, Germany,
and Spain. The Company also operated in Portugal during 1992. Spain and Portugal
were operated as fifty percent owned joint ventures until September of 1992. In
September of 1992, the Spanish joint venture became a wholly-owned subsidiary of
the Company and the Company sold its interest in the Portuguese joint venture. A
summary of certain data with respect to these operations for the fiscal years
ended December 31, 1994, January 1, 1994, and January 2, 1993 is presented
below.

  The Company operates primarily in one business segment--providing businesses
with environmentally safe and convenient solutions for managing fluid waste and
other recoverable resources.

4. INVENTORIES

  The Company's inventories consist primarily of solvent, oil and supplies. LIFO
inventories at December 31, 1994 and January 1, 1994 were $5.0 million and $4.7
million, respectively. Under the FIFO method of accounting (which approximates
current or replacement cost) inventories would have been $1.0 million and $1.8
million higher, respectively.

5. FINANCIAL ARRANGEMENTS AND LONG-TERM DEBT

  Long-term debt at December 31, 1994 and January 1, 1994 consisted of the
following:

  The long-term debt as of December 31, 1994 is due as follows:

                        In thousands

                    1996            $ 44,752
                    1997            $138,496
                    1998            $    732
                    1999            $100,015
             2000 and thereafter    $    130

  The $100 million of 9.25% Senior Notes ("the Notes") due September, 1999,
specify that, upon the occurrence of a credit agency rating decline below
investment grade, either in conjunction with a change in control or as a result
of other events as defined in the Notes, each holder of the Notes has the option
to require the Company to purchase all or any part of such holder's Notes at a
price equal to 100% of the principal amount plus accrued interest.

  In May, 1992, the Company executed interest rate swap agreements that
effectively converted $100 million of its fixed rate borrowings into variable
rate obligations. These swap agreements expire in September, 1999. In April,
1993, the Company executed an interest rate swap agreement that converted these
$100 million variable rate obligations to a fixed rate. This agreement expires
in September, 1996. The effect of these swaps reduces the interest rate on the
Notes from 9.25% to 7.08% through September, 1996. At that time the interest
reverts to a variable rate. The variable rate is based on the U.S. Dollar London
Interbank Offered Rate (LIBOR) determined at 6-month intervals.

  In May, 1992, at the same time the Company entered into the $100 million
interest rate swap agreement, the Company entered an interest rate cap
agreement, which protects the Company from rising interest rates. The cap has a
notional amount of $100 million, and expires on September 12, 1999. The cap
effectively limits the Company's interest rate exposure to 13.92% if LIBOR
exceeds 12%. The premium paid on the cap is being amortized to interest expense
over the term of the cap.

  The Company has a U.S. revolving credit agreement totalling $160 million. The
agreement provides for interest rates to be determined at the time of the
borrowing based on a choice of formulas as specified in the agreement. A
facility fee based on the Company's credit ratings is paid on the total amount
of the line of credit. At December 31, 1994, $58 million of borrowings were
outstanding at an average interest rate of 6.2%. 

  At December 31, 1994, the Company had uncommitted lines of credit totalling
$124 million. Borrowings under these lines were $74 million at an average
interest rate of 6.4%.

  The Company has the ability to convert other bank borrowings to its
revolving credit facilities.  Since the committed facilities extend beyond 1995
and the Company intends to renew these obligations, $138 million of the loans
payable to banks have been classified as long-term debt.

  The Company's German subsidiary has a revolving credit agreement totalling 76
million Deutschmarks (U.S. $49 million) that extend credit until December, 1997.
The interest rate determined at the time of each borrowing is LIBOR plus 0.5%. A
commitment fee of 0.125% per annum is paid quarterly on the unused portion of
the facility. At December 31, 1994, 70 million Deutschmarks ($45 million U.S.)
of borrowings were outstanding under this agreement at an average interest rate
of 5.8% (prior to the effect of the interest rate swap described below).

  In May, 1992, the Company's German subsidiary executed an interest rate swap
agreement which expires in May, 1997.  The interest rate on DM 70 million (U.S.
$45 million) was swapped from rates based on 6-month DM LIBOR to rates based on
6-month U.S. Dollar LIBOR.  At December 31, 1994, the effective interest rate
was 8.9%.

  At December 31, 1994, the Company's other subsidiary operations have
miscellaneous line of credit agreements totaling $7 million (U.S.). At December
31, 1994, borrowings under these lines were $2 million (U.S.) at an average
interest rate of 5.7%.

  All of the Company's interest rate swap agreements have been entered into
with major financial institutions which are expected to fully perform under the
terms of the agreements.  The Company monitors the credit ratings of these
counterparties and considers the risk of default to be remote.

  The fair value of the three interest rate swap agreements and the interest cap
agreement noted above was approximately $2.7 million less and $3.8 million
greater than the Company's carrying value at December 31, 1994 and January 1,
1994. This fair value is determined by obtaining quotes from brokers who
regularly deal in these types of financial instruments. These interest rate
swaps have resulted in a net savings of $1.8, $3.6 and $3.2 million in 1994,
1993 and 1992, respectively.

  Subsequent to year-end, the Company entered into a note purchase agreement
with two insurance companies, under which the Company borrowed $50 million at a
fixed interest rate of 8.05% for 3 years expiring in February, 1998. Proceeds
from the note were used to repay existing bank borrowings.

  The Company's credit agreements include provisions, among others, relative to
maintenance of minimum shareholders' equity and interest coverage ratios. At
December 31, 1994, the Company was in compliance with all such loan provisions.

6. CAPITAL STOCK

Preferred Stock

  The Board of Directors has the authority to issue up to 1,000,000 shares of
preferred stock, par value $.10 per share, at such time or times, in such
series, and with such designations and features thereof as it may determine,
including rate of dividend, redemption provisions and prices, conversion
conditions and prices and voting rights.  No shares of preferred stock have
been issued.

Stock Option and Employee Stock Purchase Plans

  The Company has the following stock option and employee stock purchase plans:

  1. The 1985 and 1993 Stock Option Plans (The "Option Plans")

  2. The 1988 Non-Qualified Stock Option Plan for Outside Directors (The 
     "Directors Plan")

  3. The Employee Stock Purchase Plan (the "ESPP")

  Under the Option Plans, options to purchase up to 5,937,500 shares of the
Company's common stock may be granted to officers 

                                                                              33
<PAGE>

[LOGO: SAFETY-KLEEN]
 
and other key employees at a price of 100% of the quoted market price at date of
grant. Options granted under the Option Plans may be either Incentive Stock
Options or Non-Qualified Stock Options. Stock appreciation rights (SARs) may be
granted in conjunction with Non-Qualified Stock Options whereby the grantee may
surrender exercisable Non-Qualified Options and receive a cash payment equal to 
the difference between the option price and the market value of the common
stock on the exercise date. Incentive Options, Non-Qualified Options and SARs
become exercisable at such time or times, and are subject to such conditions, as
determined by the Compensation Committee of the Board of Directors.

  Under the Directors' Plan, options to purchase up to 300,000 shares of the
Company's common stock may be granted to outside Directors at a price of 100% of
the quoted market price at the date of grant. Under the terms of the Directors'
Plan, each outside Director was granted an option to purchase 15,000 shares at
the time the plan was adopted. Any new outside Director elected or appointed
after the date the plan was adopted would also be granted an option to purchase
15,000 shares of the Company's common stock upon taking office. The Directors'
Plan also provides that a second option to purchase 15,000 shares be granted to
each outside Director on the fifth anniversary of the initial grant of options
to such Director if such Director is still serving on the Board at that time.
Options are exercisable 25% annually, on a cumulative basis, starting one year
from date of grant and terminating ten years after the grant date.

  Under the ESPP, a total of 1,500,000 shares of the Company's common stock
may be purchased by employees of the Company and designated subsidiaries,
through payroll deductions, at 90% of the quoted market price for the date
preceding the date of grant.  Under terms of the ESPP, no further grants to
purchase shares may be made after December 31, 1994.  Therefore, 1,064,571
available option shares not granted as of December 31, 1994 have expired. 
Officers of the Company, employees with less than six months of service or
employees who hold options under the 1985 Stock Option Plan are not eligible to
participate in this Plan.

  A summary of the status of the Company's stock option plans for the three
fiscal years ended December 31, 1994, is presented below.

Shareholders' Rights Plan

  Pursuant to a plan adopted by the Company in December, 1988, each share of the
Company's common stock carries the right to buy one share of the Company's
common stock at a price of $73.33 per share. The rights will expire on November
21, 1998, unless earlier redeemed by the Company. The rights will become
exercisable if a person becomes an "acquiring person" by acquiring 20% of the
Company's common stock or announces a tender offer that would result in such
person owning 20% or more of the Company's common stock. If someone becomes an
acquiring person (except pursuant to certain cash tender offers for all shares),
the holder of each right (other than rights owned by the acquiring person) will
be entitled to purchase common stock of the Company having a market value of
twice the exercise price of the right. In addition, if the Company is acquired
in a merger or other business combination transaction in which the Company's
common stock is exchanged for cash or securities, or 50% or more of its
consolidated assets or earning power are sold, each holder (other than the
acquiring person) will have the right to purchase

common stock of the acquiring company having a market value of twice the
exercise price. The rights may be redeemed by the Company, at a price of 0.67
cents per right, at any time prior to anyone becoming an acquiring person.

7. PENSION AND EMPLOYEE BENEFIT PLANS

  The Company has noncontributory pension plans covering substantially all
full time employees in the United States.  Domestic pension costs are funded in
compliance with ERISA requirements as employees become eligible to participate,
generally, after completing one year of service.

  The Company's consolidated pension costs for fiscal years 1994, 1993 and
1992 were $5.5 million, $7.2 million, and $4.0 million, respectively. The 1993
pension costs include $2.4 million incurred in conjunction with a restructuring
plan more fully described in Management's Discussion and Analysis of Financial
Condition and Results of Operations--Restructuring and Special Charges on page
24.

  The following table sets forth the domestic plans' combined funded status
at December 31, 1994, and January 1, 1994:

  The Company also has pension plans covering employees of its Canadian and
British subsidiaries. Those plans are funded by purchase of insurance contracts
and units in a managed fund invested in stocks, fixed income securities and real
estate. Vested benefits are fully funded. The Company's foreign subsidiaries are
not required to report under ERISA and do not otherwise determine the actuarial
value of accumulated plan benefits as disclosed above for the Company's domestic
pension plans. These plans do not have a material effect on the Company's
financial condition or results of operations.

  The Safety-Kleen Corp. Savings and Investment Plan allows 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. The Company
may, at its discretion, make matching contributions out of its profits for the
year. The Company's expense for contributions was $1.5 million in 1994, and $1.1
million in 1992. The Company did not make a matching contribution for 1993.

                                                                           35

  The Company offers a post-retirement medical insurance plan to its domestic
employees retiring prior to the normal retirement age of 65.  Retirees are
eligible to continue this medical coverage until age 65.  The plan is currently
unfunded and retirees electing this coverage are required to pay a premium for
the insurance.

  The Company adopted Statement of Financial Accounting Standards (SFAS) No.
106 on accounting for employees' post-retirement benefits during the fourth
quarter of 1992 retroactive to the beginning of the year.  This statement
requires the accrual of the cost of providing post-retirement health care
coverage over the active service period of the employee.  Prior to 1992, these
costs were charged to operating expenses in the year paid and were immaterial. 
The Company elected to immediately recognize the accumulated liability in 1992.

  The following table reconciles the funded status of the plan to the accrued
post-retirement benefit cost recognized in the Consolidated Balance Sheets at
December 31, 1994 and January 1, 1994:

  Net periodic post-retirement benefit costs for 1992 were not material.

  The health care cost trend was assumed to be 11% for 1994 decreasing by 2%
per year through 1997, then to an ultimate trend of 4.5% in 1998.

  If the health care cost trend rate increases one percent for all future
years, the accumulated post-retirement benefit obligation as of December 31,
1994, would have increased 17.1%.  The effect of this change on the aggregate
of the service and interest cost for 1994 would be an increase of 20.5%.

  The Company also adopted SFAS No. 112 on accounting for post-employment
benefits during 1993.  The effect of adopting this change was not material.

  Effective at the beginning of fiscal year 1992, the Company adopted SFAS No.
109 on accounting for income taxes.  This adoption resulted in an increase in
net earnings of $3.2 million or $.06 per share for the cumulative effect of
prior years' income.  The effect of the adoption on income for fiscal year
1992, was not material.

  Under SFAS No. 109, deferred tax assets and liabilities are computed based on
the difference between the financial statement and income tax bases of assets
and liabilities using the enacted tax rates. The provisions (benefits) for
income taxes include the following:

  The Company has recorded a valuation allowance of approximately $3.2 million
for unrealized NOL tax assets that may expire before the Company is able to
utilize such NOLs.

  The valuation allowance account balance of $3.2 million represents
approximately 57% of the NOL tax assets that are due to expire as compared to a
valuation allowance percentage of approximately 72% of the NOLs due to expire
at the end of 1993.  The valuation account balance activity is summarized in
the table below.

9. SPECIAL CHARGE FOR ENVIRONMENTAL COST, OTHER ACCRUED EXPENSES AND
LIABILITIES, COMMITMENTS AND CONTINGENT LIABILITIES

  The Company operates a large number of facilities for the collection and
processing of hazardous and non-hazardous wastes and is subject to extensive and
expansive regulation by Federal, state and local authorities.

  In the ordinary course of conducting its business activities, the Company
becomes involved in judicial and administrative proceedings in which
governmental authorities seek remedial actions and/or fines and penalties. The
Company also has been notified by the EPA that it may be a responsible party at
several National Priority List ("NPL") sites. Generally, these proceedings by
Federal and state regulatory agencies have been resolved by negotiation and
settlement. Based on its past experience and its knowledge of pending cases, the
Company believes it is unlikely that the Company's actual liability on cases now
pending will be materially adverse to the Company's financial condition. It
should be noted, however, that many environmental laws are written in a way in
which the Company's potential liability can be large and it is always possible
that the Company's actual liability on any particular environmental claim will
prove to be larger than anticipated or accrued for by the Company. It is also
possible that expenses incurred in any particular reporting period for
remediation costs or for fines, penalties or judgments could have a material
impact on the Company's results of operations for that period.

  Under various Federal, state and local regulations, the Company can be
required to conduct an environmental investigation of any of its permitted
operating or closed facilities to determine the possible existence and extent of
environmental contamination. In the event that contamination is found, the
Company may be required to perform a remedial cleanup of the site. The Company
is currently engaged in investigation and cleanup work at many of its sites.

  In 1993 the Company recorded a $50 million pre-tax special charge ($30 million
after-tax or $0.52 per share) for a change in estimate for remediation costs
relating to all operating and previously-closed sites prior to conducting
detailed individual site investigations to ascertain the existence and extent of
contamination. This change results in earlier recognition of environmental
remediation costs and liabilities as compared with the Company's previous
practice which was to accrue the estimated cost of remedial cleanup work at the
time the need for such work was specifically identified based on site
investigation.

  Federal environmental regulations require that the Company demonstrate
financial responsibility for sudden and non-sudden releases, as well as closure
and post-closure liabilities. One manner by which to make this demonstration is
through Environmental Impairment Liability (EIL) insurance coverage. The Company
has EIL insurance coverage which it believes complies with the Federal
regulatory requirements. However, the Company must reimburse the insurance
carrier for all losses and expenses incurred by it under the policy. The
Company's income could be adversely affected in the future if it is unable to
obtain risk-transfer EIL insurance coverage and uninsured losses were to be
incurred.

  The Company leases certain of its branches, vehicles and other equipment. 
These leases are accounted for as operating leases.  Related rental expenses
were $21.2 million in 1994, $20.8 million in 1993 and $20.3 million in 1992.

  Aggregate minimum future rentals are payable as follows:

10. 1993 RESTRUCTURING CHARGE

  During the fourth interim period of 1993 the Company adopted a restructuring
plan based on conversion of its core Parts Cleaner Service to new technology
and other strategic actions.  In conjunction with the adoption of this plan,
the Company recorded a special charge of $179 million ($106 million after tax
or $1.84 per share) in the fourth quarter.  The pre-tax restructuring charge
included $93 million of asset write-downs and $86 million of other
restructuring charges.

11. PROPERTY PLANT & EQUIPMENT HELD FOR SALE

  The net book value of property intended for sale as a result of planned
recycling capacity reductions, facility shutdowns and other restructuring
action taken during the fourth interim period of 1993 was $16.4 and $16.6
million, as of December 31, 1994 and January 1, 1994, respectively.

SAFETY-KLEEN CORP. TOPS $50 MILLION IN NET EARNINGS FOR 1994
------------------------------------------------------------

ELGIN, IL, February 10, 1995 -- Donald W. Brinckman, Chairman of Safety-Kleen
Corp., announced today that the Company achieved $50.1 million, or $.87 per
share, in net earnings for the full year 1994.  This represents an increase of
45% over net earnings reported for 1993.  This comparison and all of the
remaining comparisons to 1993 are before restructuring and special charges
recorded in 1993.  Fourth quarter 1994 net earnings were $16.7 million, or $.29
per share, an increase of 72% from 1993 net earnings of $9.7 million, or $.17
per share .  Revenue for the fourth quarter 1994 increased 3% to $249.0 million.
Revenue for the full year 1994 was $791.3 million, down $4.2 million, or 0.5%,
from last year.  Revenue for the fourth quarter and the year was up 6% and 2%,
respectively, excluding the 1993 revenue of product lines and other businesses
that were discontinued in 1994.

Revenues from the North American Automotive/Retail Repair Service and the North
American Industrial Parts Cleaner Service totaled $351 million for the full year
1994, down 4% from last year. This decline in revenues is primarily due to
planned discontinuance of Allied Product sales in 1994 and an increase in the
average parts cleaner service interval.  Total parts cleaners in service
worldwide increased 15,300 units, or 3%, during 1994.  This compares to a net
decrease of 14,100 units, or 2%, for 1993.  The fourth quarter of 1994 showed
the largest quarterly gain of the year with a net increase of 6,500 units in
service from the end of the third quarter.  The improved year-to-year
performance is due primarily to a reduction in the turnover rate of existing
customers as the Company continued to convert customers to the new cyclonic
parts cleaner.

Revenue of the Industrial Fluid Recovery Service grew 13% to $109 million in
1994.  However, in the fourth quarter, revenue of this service grew 18% over
1993.  The Company increased the number of

Branch Industrial Managers selling to this market by 17% in 1994 and plans to
add another 35% in 1995.

Revenue of the Oil Recovery Service was $118 million in 1994, up 4% from last
year.  Net income for these operations was approximately $1.5 million in 1994,
as compared to a net loss of $1.3 million in 1993.

Revenue of the Company's European operations totaled $85 million, an increase of
7% from 1993.  The European operations reported net earnings of approximately
$0.8 million, as compared to a net loss of $2.2 million in 1993.

Brinckman said, "The Company is in the process of rolling out its new Imaging
Services business.  Subsequent to year-end we completed the acquisition of Drew
Resources Corp., a California based photochemical equipment and service provider
with approximately 2,000 customers.  This acquisition, along with the previously
announced acquisition of the Boston Recovery Company, should help to accelerate
the growth of this new business area for Safety-Kleen.  In January, 1995 we also
acquired a parts cleaner service business from Sparkle Corp., which should add
approximately $5 million of annual revenue.  This acquisition confirms our
commitment to grow this core business."

"Our operating margin in the current quarter was 13.2% of revenue, up from 8.0%
in 1993.  For the full year our operating margin increased from 8.9% in 1993 to
12.6% in 1994.  These improvements are primarily the result of the restructuring
actions begun in the fourth quarter of 1993, and improved pricing in certain of
our services in 1994."

Brinckman concluded, "We experienced substantial year-to-year earnings
improvements in most of our operations in 1994.  The cyclonic parts cleaner has
been well received, with almost 103,000 of these units in service at year-end
1994.  This has led to renewed growth in units in service in the
Automotive/Retail Repair market and increased growth in the Industrial Parts
Cleaner market.  In

addition, we are seeing excellent growth in the Industrial Fluid Recovery
Service. We believe that the Imaging Services market offers an exciting new
growth opportunity for the Company. Further, our European operations turned
profitable in 1995, and we believe these operations should continue to improve
in profitability as we increase the customer base in Europe. We believe we are
entering 1995 with a good deal of momentum and look forward to continued
earnings growth."

1. The Company recorded restructuring and special charges to operating expense
   of $229 million ($136 million or $2.36 per share, after tax) in the fourth
   interim period of 1993. The total includes $179 million of asset write-downs
   and other charges related to a restructuring program announced in December,
   1993, and $50 million for a change in accounting estimate for future
   environmental remediation costs relating to all operating and previously
   closed Company sites. The Company also recorded a $1.5 million increase in
   income tax expense in the third interim period of 1993 to revalue the prior
   year deferred tax balance primarily due to an increase in the statutory
   income tax rate in the United States.

2. The Company's interim reporting periods are twelve weeks each for the first
   three reporting periods of the year and sixteen weeks for the fourth
   reporting period.
