                                    PART I
 
ITEM 1. BUSINESS.
 
GENERAL
 
  Waste Management, Inc. (formerly "WMX Technologies, Inc.") is a leading
international provider of waste management services. Unless the context
indicates to the contrary, as used in this report the terms "Company" and
"Waste Management" refer to Waste Management, Inc. and its subsidiaries.
 
  The Company provides integrated solid waste management services in North
America through Waste Management of North America, Inc., a wholly owned
subsidiary of the Company (referred to herein, together with its subsidiaries
and certain affiliated companies providing waste management and related
services, as "WMNA"). The Company's solid waste management services are
provided to commercial, industrial, municipal and residential customers, as
well as to other waste management companies, and consist of solid waste
collection, transfer, resource recovery and disposal services. As part of
these services, the Company is engaged in providing, through its Recycle
America(R) and other programs, paper, glass, plastic and metal recycling
services to commercial and industrial operations and curbside collection of
such materials from residences and in removing methane gas from sanitary
landfill facilities for use in electricity generation. In addition, through
WMNA, the Company provides Port-O-Let(R) portable sanitation services to
municipalities and commercial and special event customers. WMNA also manages
the on-site industrial cleaning services businesses owned by the Company's
Rust International Inc. subsidiary. In June 1997, the Company completed the
sale of most of the Company's solid waste assets in Canada to a subsidiary of
USA Waste Services, Inc. ("USA Waste"). See Note 5 to Consolidated Financial
Statements set forth in Item 8 herein.
 
  The Company also provides hazardous waste management services. The Company's
chemical waste treatment, storage, disposal and related services in North
America are provided through WMNA and Chemical Waste Management, Inc., a
wholly owned subsidiary of the Company (referred to herein, together with its
subsidiaries, as "CWM"), and are provided to commercial and industrial
customers, as well as to other waste management companies and to governmental
entities. Through Advanced Environmental Technical Services, L.L.C., a wholly
owned subsidiary of the Company (referred to herein, together with its
subsidiaries as "AETS"), the Company provides on-site integrated hazardous
waste management services, including hazardous waste identification,
packaging, removal and recycling services, to industrial, institutional and
governmental customers. Through its wholly owned Chem-Nuclear Systems, L.L.C.
subsidiary (referred to herein, together with its subsidiaries, as "Chem-
Nuclear"), the Company also furnishes radioactive waste management services,
primarily to electric utilities and governmental entities.
 
  The Company provides comprehensive waste management and related services
outside North America through Waste Management International plc, a subsidiary
owned approximately 56% by the Company and 12% each by the Company's Rust
International Inc. and Wheelabrator Technologies Inc. subsidiaries (referred
to herein, together with its subsidiaries, as "WM International"). WM
International provides a wide range of solid and hazardous waste management
services in seven countries in Europe, seven countries in the Asia-Pacific
region and Argentina, Brazil, and Israel.
 
  Wheelabrator Technologies Inc., an approximately 67%-owned subsidiary of the
Company (referred to herein, together with its subsidiaries, as "WTI"), is a
leading developer of facilities for, and provider of services to, the trash-
to-energy and waste-fuel powered independent power markets. WTI develops,
arranges financing for, operates and owns facilities that dispose of trash and
other waste materials in an environmentally acceptable manner by recycling
them into electrical or steam energy. WTI is also pursuing the development,
ownership and operation of power plants for industrial customers. In addition,
WTI is involved in the treatment and management of biosolids resulting from
the treatment of wastewater by converting them into useful fertilizers and the
recycling of organic wastes into compost material useable for horticultural
and agricultural purposes. WTI also designs and installs technologically
advanced air pollution control systems and equipment. In 1996, WTI sold its
water process, manufacturing and custom engineering business and in 1997 sold
its water-contract operations, outsourcing and privatization business. See
"Management's Discussion and Analysis of Results of Operations and Financial
Condition" herein.

                                                                           LOGO

  In June 1997, the Company announced an offer to acquire, for $15 per share
in cash, all of the approximately 53 million outstanding shares of WTI it does
not already own. The price was increased to $16.50 per share pursuant to a
definitive merger agreement subsequently negotiated with a special committee
of independent WTI directors. The terms of the agreement have been approved by
the WTI special committee and by the Boards of Directors of the Company and
WTI, but the transaction remains subject to the approval of the holders of a
majority of WTI's outstanding shares, other than those held by the Company,
voting on it at a special meeting of WTI stockholders to be held March 30,
1998. Several lawsuits have been filed which seek, among other things, to
enjoin the proposed transaction. The Company believes that it has met the
legal standards applicable to transactions of this type and intends to
vigorously defend itself in these lawsuits.
 
  Rust International Inc., a subsidiary owned approximately 60% by the Company
and 40% by WTI (referred to herein, together with its subsidiaries, as
"Rust"), is engaged in furnishing environmental and infrastructure consulting
and a variety of other on-site industrial and related services primarily to
clients in the public sector and petrochemical, chemical, energy, utility,
pulp and paper, environmental services and other industries. In early 1998,
Rust sold its approximately 37% interest in OHM Corporation, a publicly traded
provider of environmental remediation services ("OHM"), and received a
distribution from OHM of additional shares of NSC Corporation, a publicly
traded provider of asbestos abatement and other specialty contracting services
("NSC"). The distribution increased Rust's interest in NSC from approximately
40% to 54%.
 
  The Company's strategic plans call for the Company to focus on the provision
of waste management services and to sell or discontinue various businesses
which do not fit within that focus. The Company has therefore reported its
continuing operations as being within a single industry segment, waste
management services. The Company's continuing consolidated revenues were
approximately $8.5 billion in 1994, $9.1 billion in 1995, $9.2 billion in 1996
and $9.2 billion in 1997. For information relating to the Company's operations
in different geographic groups, see Note 14 to the Company's Consolidated
Financial Statements set forth below in Item 8. For interim periods, the
revenues and net income of certain of the Company's operations may fluctuate
for a number of reasons, including there being for some businesses less
activity during the winter months.
 
  On March 10, 1998, the Company entered into a definitive merger agreement
(the "Merger Agreement") with USA Waste Services, Inc. ("USA Waste") pursuant
to which the Company will be merged with a wholly-owned subsidiary of USA
Waste (the "Merger"). Pursuant to the Merger Agreement, the Company's
stockholders will receive .725 shares of common stock of USA Waste for each
share of common stock of the Company. The consummation of the Merger is
subject to a number of conditions, including the expiration or termination of
the applicable merger review waiting period under the Hart-Scott-Rodino Anti-
Trust Improvements Act of 1976, approval by the stockholders of each company
and other typical closing conditions. In addition, the Merger is contingent
upon the transaction qualifying for pooling-of-interests accounting treatment.
In order to qualify for pooling-of-interests accounting treatment, the Company
intends to sell a portion of its treasury shares pursuant to a registered
public offering prior to the closing of the Merger. A lawsuit by an alleged
Company stockholder purporting to represent a class of the Company's
stockholders has been filed (although the Company has not yet been served)
against the Company and members of its Board of Directors alleging breaches of
fiduciary duty by the defendants in connection with the Merger. The lawsuit
seeks, among other things, to have the transaction enjoined and to recover
unspecified damages. The Company believes the suit to be without merit and
intends to contest it vigorously.
 
  Regulatory or technological developments relating to the environment may
require companies engaged in waste management services and related businesses,
including the Company, to modify, supplement or replace equipment and
facilities at costs which may be substantial. Because the continuing business
in which the Company is engaged is intrinsically connected with the protection
of the environment and the potential discharge of materials into the
environment, a material portion of the Company's capital expenditures is,
directly or indirectly, related to such items. See "Management's Discussion
and Analysis of Results of Operations and Financial Condition--Financial
Condition" set forth below in Item 7 for a review of property and equipment
expenditures by the Company for the last four years. The Company believes
that, in general, it tends to benefit when environmental regulation increases,
which may increase the demand for its services, and that it has the resources
and experience to manage environmental risk.
 
                                       2
<PAGE>
 
  Although the Company strives to conduct its operations in compliance with
applicable laws and regulations, the Company believes that in the existing
climate of heightened legal, political and citizen awareness and concerns,
companies in the waste management services industry, including the Company,
will be faced, in the normal course of operating their businesses, with fines
and penalties and the need to expend funds for remedial work and related
activities with respect to waste treatment, disposal and trash-to-energy
facilities. Where the Company concludes that it is probable that a liability
has been incurred, a provision is made in the Company's financial statements
for the Company's best estimate of the liability based on management's judgment
and experience, and information available from regulatory agencies. This
estimate is also based upon an analysis of the number, financial resources and
relative degree of responsibility of other potentially responsible parties who
are jointly and severally liable for remediation of a specific site, as well as
the typical allocation of costs among such parties. If a range of possible
outcomes is estimated and no amount within the range appears to be a better
estimate than any other, then the Company provides for the minimum amount
within the range, in accordance with generally accepted accounting principles.
Such estimates are subsequently revised, as necessary, as additional
information becomes available. While the Company does not anticipate that the
amount of any such revision will have a material adverse effect on the
Company's operations or financial condition, the measurement of environmental
liabilities is inherently difficult and the possibility remains that
technological, regulatory or enforcement developments, the results of
environmental studies, the existence and ability of other potentially
responsible third parties (including insurance carriers) to contribute to the
settlement of such liabilities or other factors could materially alter this
expectation at any time. Such matters could have a material adverse impact on
earnings for one or more fiscal quarters or years.
 
  While in general the Company's business has benefited from increased
governmental regulation, the business itself is subject to extensive and
evolving regulation by federal, state, local and foreign authorities. Due to
the complexity of regulation of the industry and to public pressure,
implementation of existing and future laws, regulations or initiatives by
different levels of government may be inconsistent and difficult to foresee. In
addition, the demand for certain of the Company's services may be adversely
affected by the amendment or repeal, or reduction in enforcement of, federal,
state and foreign laws and regulations on which the Company's business is
dependent. Demand for certain of the Company's services may also be adversely
affected by delays or reductions in funding, or failure of legislative bodies
to fund, agencies or programs under such laws and regulations. Although it is
not always able to do so, the Company makes a continuing effort to anticipate
regulatory, political and legal developments that might affect its operations.
The Company cannot predict the extent to which any legislation or regulation
that may be enacted, amended, repealed or enforced, or any failure or delay in
enactment or enforcement of legislation or regulations or funding of agencies
or programs, in the future may affect its operations.
 
  The Company was incorporated in Delaware in 1968 and subsequently succeeded
to certain businesses owned by its organizers and others. The Company's common
stock is listed on the New York Stock Exchange under the trading symbol "WMX"
and is also listed on the Frankfurt Stock Exchange, the London Stock Exchange,
the Chicago Stock Exchange and the Swiss Stock Exchanges in Basle, Zurich and
Geneva.
 
  Unless the context indicates to the contrary, all statistical and financial
information under Item 1 and Item 2 of this report is given as of December 31,
1997. Also, unless the context indicates to the contrary, statistical and
financial data appearing under the caption "North American Solid and Hazardous
Waste Management Services" relate only to the Company's WMNA, CWM, AETS and
Chem-Nuclear groups of subsidiaries and do not include any data relating to
Rust, Rust's on-site industrial cleaning services business managed by WMNA, WTI
or WM International. For discussions of the data relating to WM International
and WTI, see "International Waste Management and Related Services" and "Trash-
to-Energy and Related Services."
 
NORTH AMERICAN SOLID AND HAZARDOUS WASTE MANAGEMENT SERVICES
 
  The Company's North American solid waste management and recycling services
include residential, commercial and industrial collection, transfer and
disposal services and related services provided by WMNA.

The Company's North American hazardous waste management services include
chemical waste treatment, storage, disposal and related services provided by
WMNA and CWM, on-site integrated hazardous waste management services provided
by AETS and low-level radioactive waste disposal services provided by Chem-
Nuclear. Many of the Company's solid and hazardous waste services are marketed
on an integrated basis to the Company's national account customers and to other
large industrial customers.
 
  For each of the four years in the period ended December 31, 1997, the North
American solid and hazardous waste revenue amounted to 67.3%, 67.5%, 68.2% and
68.0%, respectively, of the Company's total revenues. For each of the four
years in the period ended December 31, 1997, the following table shows the
percentages of the Company's total North American solid and hazardous waste
services revenue (excluding on-site industrial cleaning services revenue)

SOLID WASTE MANAGEMENT, RECYCLING AND RELATED SERVICES
 
  At December 31, 1997, WMNA conducted solid waste management, recycling and
related services operations in 47 states, the District of Columbia, Canada and
Mexico. During 1994, 1995, 1996 and 1997, operations in California, Florida and
Pennsylvania together accounted for approximately 31%, 29%, 26% and 29%,
respectively, of North American solid waste revenue. No customer accounted for
as much as 3% of such revenue in 1994, 1995, 1996 or 1997.
 
COLLECTION
 
  WMNA provides solid waste collection services to approximately 1.1 million
commercial and industrial customers. Collection services are also provided to
approximately 11.8 million homes and apartment units. These services in many
cases include collection of recyclable commodities. See "Recycling and Energy
Recovery--Recycling" for a description of recycling services.
 
 Commercial and Industrial
 
  Many of WMNA's commercial and industrial customers utilize containers to
store solid waste, including "roll-offs," which are large containers that are
dropped off at construction or other sites for the deposit of waste and then
hoisted when full onto a truck for transport. These containers, ranging from 1
to 45 cubic yards in size, are usually provided to the customer as part of
WMNA's services. Stationary compactors, which compact the volume of the stored
waste prior to collection, are frequently installed on the premises of large
volume customers and are usually provided to these customers in conjunction
with WMNA's collection services. Containerization enables WMNA to service most
of its commercial and industrial customers with collection vehicles operated by
a single employee. Compaction serves to decrease the frequency of collection.
 
  Commercial and industrial collection services (which include containerized
service to apartment buildings) are generally performed under one- to three-
year service agreements. Fees are determined by such considerations as market
factors, collection frequency, type of equipment furnished, length of service
agreement, type and volume or weight of the waste collected, distance to the
disposal facility and cost of disposal.

 Residential
 
  Most of WMNA's residential solid waste collection services are performed
under contracts with, or franchises granted by, municipalities giving WMNA
exclusive rights to service all or a portion of the homes in their respective
jurisdictions. Such contracts or franchises usually range in duration from one
to five years. The fees received by WMNA are based primarily on market factors,
frequency and type of service, the distance to processing or disposal
facilities and cost of processing or disposal. Residential collection fees are
either paid by the municipalities out of tax revenues or service charges or are
paid directly by the residents receiving the service.
 
TRANSFER
 
  WMNA operates 164 solid waste transfer stations. A transfer station is a
facility where solid waste is received from collection vehicles and then
transferred to, and in some cases compacted in, large, specially constructed
trailers for transportation to disposal or resource recovery facilities. This
procedure reduces costs by improving utilization of collection personnel and
equipment and improving the efficiency of transporting waste to final disposal
facilities.
 
  The services of these facilities are provided to municipalities or counties
and in most instances are also used by WMNA and by other collection companies.
Fees are generally based upon such considerations as competition, the type and
volume or weight of the waste transferred, the extent of processing of
recyclable materials, the transport distance involved and the cost of disposal.
 
RECYCLING AND ENERGY RECOVERY
 
 Recycling
 
  WMNA provides recycling services in the United States through its Recycle
America(R) and other programs. Recycling involves the removal of reusable
materials from the waste stream for processing and sale or other disposition
for use in various applications. Participating commercial and industrial
operations use containers to separate recyclable paper, glass, plastic and
metal wastes for collection, processing and sale by WMNA. Fees are determined
by such considerations as competition, frequency of collection, type and volume
or weight of the recyclable material, degree of processing required, distance
the recyclable material must be transported and value of the recyclable
material.
 
  As part of its residential solid waste collection services, WMNA engages in
curbside collection of recyclable materials from residences in the United
States, also through its Recycle America(R) and other programs. Curbside
recycling services generally involve the collection of recyclable paper, glass,
plastic and metal waste materials, which may be separated by residents into
different waste containers or commingled with other recyclable materials. The
recyclable materials are then typically deposited at a local materials recovery
facility where they are sorted and processed for resale.
 
  The prices received by the Company for recyclable materials fluctuate
substantially from quarter to quarter and year to year depending upon domestic
and foreign demand for such materials, the quality of such materials, prices
for new materials and other factors. In some instances, the Company enters into
agreements with customers or the local governments of municipalities in which
it provides recycling services whereby the customers or the governments share
in the gains and losses resulting from fluctuation in prices of recyclable
commodities. These agreements mitigate both the Company's gains and losses from
such fluctuations.
 
  As of December 31, 1997, WMNA provided curbside recycling services to
approximately 7.9 million households in the United States. WMNA has
approximately 211,000 commercial and industrial recycling services customers.
 
  WMNA operates 129 materials recovery facilities for the receipt and
processing of recyclable materials. Such processing consists of separating
recyclable materials according to type and baling or otherwise preparing the
separated materials for sale.
 
                                       5
<PAGE>
 
  WMNA also participates in joint ventures with Stone Container Corporation
and American National Can Corporation to engage, respectively, in the
businesses of marketing paper fibre and aluminum, steel, and glass containers
for recycling. In each case WMNA sells to the joint venture, or has the joint
venture market, the paper fibre or containers collected by WMNA to Stone
Container, American National Can or other parties who will process them for
reuse. The joint venture with American National Can also owns and operates six
glass processing facilities. During 1997, the Stone Container joint venture
marketed approximately 2.1 million tons of paper fiber and the American
National Can joint venture processed approximately 466,000 tons of other
recyclable materials. WMNA also provides tire and demolition and construction
debris recycling services.
 
 Energy Recovery
 
  At 38 WMNA-owned or -operated sanitary landfill facilities, WMNA is engaged
in methane gas recovery operations. These operations involve the installation
of a gas collection system into a sanitary landfill facility. Through the gas
collection system, gas generated by decomposing solid waste is collected and
transported to a gas-processing facility at the landfill site. Through
physical processes methane gas is separated from contaminants. The processed
methane gas generally is then either sold directly to industrial users or to
an affiliate of the Company which uses it as a fuel to power electricity
generators. Electricity generated by these facilities is sold, usually to
public utilities under long-term sales contracts, often under terms or
conditions which are subject to approval by regulatory authorities.
 
  The Company also engages in other resource recovery activities through WTI's
trash-to-energy and related operations and Waste Management International's
operations. See "Trash-to-Energy and Related Services" and "International
Waste Management and Related Services."
 
DISPOSAL
 
  WMNA operates 130 solid waste sanitary landfill facilities. Of this number,
101 are owned by WMNA and the remainder are leased from, or operated under
contract with, other parties. Additional facilities are in various stages of
development. WMNA also provides yard-waste composting services, bioremediation
of petroleum-contaminated soils and solidification of difficult-to-treat
liquid wastes at a number of its disposal facilities. All of the sanitary
landfill facilities are subject to governmental regulation. See "Regulation--
Waste Management Services--Solid Waste."
 
  A sanitary landfill site must have geological and hydrological properties
and design features which limit the possibility of water pollution, directly
or by leaching. Sanitary landfill operations, which include carefully planned
excavation, continuous spreading and compacting of solid waste and covering of
the waste, are designed to maintain sanitary conditions, insure optimum
utilization of the airspace and prepare the site for ultimate use for other
purposes. Landfill site operations are required to be conducted in accordance
with the terms of permits obtained from various regulatory authorities, which
typically incorporate the requirements of Subtitle D of the Resource
Conservation and Recovery Act of 1976 ("RCRA") or applicable state
requirements, whichever are stricter. These requirements address such matters
as daily volume limitations, placement of daily, interim and final site cover
materials on waste disposed at the site, construction and operation of methane
gas and leachate management systems, periodic groundwater monitoring activity
and final closure requirements and post-closure monitoring and maintenance
activities.
 
  Suitable sanitary landfill facilities and permission to expand existing
facilities may be difficult to obtain in some areas because of land scarcity,
local resident opposition and governmental regulation. As its existing
facilities become filled in such areas, the solid waste disposal operations of
WMNA are and will continue to be materially dependent on its ability to
purchase, lease or otherwise obtain operating rights for additional sites or
expansion of existing sites and to obtain the necessary permits from
regulatory authorities to construct and operate them. In addition, there can
be no assurance that additional sites can be obtained or that existing
facilities can continue to be expanded or operated. However, management
believes that the facilities currently available to WMNA are sufficient to
meet the needs of its operations in most areas for the foreseeable future.
 
                                       6
<PAGE>
 
  To develop a new facility, WMNA must expend significant time and capital
resources without any certainty that the necessary permits will ultimately be
issued for such facility or that the Company will be able to achieve and
maintain the desired disposal volume at such facility. If the inability to
obtain and retain necessary permits, the failure of a facility to achieve the
desired disposal volume or other factors cause WMNA to abandon development
efforts for a facility, the capitalized development expenses of the facility
are written off.
 
  In varying degrees, WMNA utilizes its own sanitary landfill facilities to
accommodate its disposal requirements for collection and transfer operations.
In 1994, 1995, 1996 and 1997 approximately 55%, 57%, 60% and 61%,
respectively, of the solid waste collected by WMNA was disposed of in sanitary
landfill facilities operated by it. Usually these facilities are also used by
other companies and government agencies on a noncontract basis for fees
determined by such considerations as competition and the type and volume or
weight of the waste.
 
RELATED SERVICES
 
  WMNA also provides or manages several types of services which are compatible
with its solid waste collection operations. Included in these operations are
on-site industrial cleaning services and portable sanitation services.
 
  WMNA manages the business of Rust Industrial Services Inc., a subsidiary of
Rust ("RIS"), which provides on-site industrial services, including water
blasting, tank cleaning, explosives blasting, chemical cleaning, industrial
vacuuming, catalyst handling and separation technologies. RIS provides these
services primarily for clients in the petrochemical, chemical, and pulp and
paper industries, utilities and, to a lesser extent, the public sector. RIS
also assists clients in the nuclear and utility industries in solving
electrical, mechanical, engineering and related technical services problems.
 
  Prior to selling the businesses in 1996 and early 1997, RIS also provided
scaffolding rental and erection services primarily to the chemical,
petrochemical and utilities industries and a variety of other on-site
services.
 
  Waste Management Federal Services, Inc., a subsidiary of Rust, also provides
hazardous, radioactive and mixed waste program and facilities management
services, primarily to the United States Department of Energy and other
federal government agencies. Such services include waste treatment, storage,
characterization and disposal and privatization services.
 
  WMNA also provides portable sanitation services to municipalities and
commercial customers. The portable sanitation services, which are marketed
under the Port-O-Let(R) trade name, are also used at numerous special events
and public gatherings.
 
HAZARDOUS WASTE MANAGEMENT AND RELATED SERVICES
 
CHEMICAL WASTE MANAGEMENT SERVICES
 
  The Company operates chemical waste treatment, storage and disposal
facilities in 18 states and also owns a majority interest in a subsidiary
which operates a resource recovery and storage facility and a disposal
facility in Mexico. The chemical wastes handled by the Company include
industrial by-products and residues that have been identified as "hazardous"
pursuant to RCRA, as well as other materials contaminated with a wide variety
of chemical substances.
 
  Chemical waste may be collected from customers and transported by WMNA or
CWM or contractors retained by them or delivered by customers to their
facilities. Chemical waste is transported primarily in specially constructed
tankers and semi-trailers, including stainless steel and rubber or epoxy-lined
tankers and vacuum trucks, or in containers or drums on trailers designed to
comply with applicable regulations and specifications of the U.S. Department
of Transportation ("DOT") relating to the transportation of hazardous
materials. WMNA and CWM also operate several facilities at which waste
collected from or delivered by customers may be analyzed and consolidated
prior to further shipment.
 
 
                                       7
<PAGE>
 
  All of the Company's seven United States secure hazardous waste land disposal
facilities have been issued permits under RCRA. See "Regulation--RCRA." In
general, the Company's secure land disposal facilities have received the
necessary permits and approvals to accept chemical wastes, although some of
such sites may accept only certain chemical wastes. Only chemical wastes in a
stable, solid form which meet applicable regulatory requirements may be buried
in the Company's secure disposal cells. These land disposal facilities are
sited, constructed and operated in a manner designed to provide long-term
containment of such waste. Chemical wastes may be treated prior to disposal.
Physical treatment methods include distillation, evaporation and separation,
all of which effectively result in the separation or removal of solid materials
from liquids. Chemical treatment methods include chemical oxidation and
reduction, chemical precipitation of heavy metals, hydrolysis and
neutralization of acid and alkaline wastes and essentially involve the
transformation of wastes into inert materials through one or more chemical
reaction processes. At two of its locations, the Company isolates treated
chemical wastes in liquid form by injection into deep wells. Deep well
technology involves drilling wells in suitable rock formations far below the
base of fresh water and separated from it by other substantial geological
confining layers.
 
  AETS provides on-site integrated hazardous waste management services,
including hazardous waste identification, packaging, removal and recycling
services in North America. These services include on-site hazardous waste data
management, education and training, inventory control and other administrative
services, lab pack services, drum identification services, household hazardous
waste programs, less-than-full load waste pickup and consolidation services,
and related services. AETS provides these services primarily to industrial,
institutional and public sector customers, including laboratories.
 
  In the United States, most chemical wastes generated by industrial processes
are handled "on-site" at the generators' facilities. Since the mid-1970's,
public awareness of the harmful effects of unregulated disposal of chemical
wastes on the environment and health has led to extensive and evolving federal,
state and local regulation of chemical waste management activities. The major
federal statutes regulating the management of chemical wastes include RCRA, the
Toxic Substances Control Act ("TSCA") and the Comprehensive Environmental
Response, Compensation and Liabilities Act of 1980, as amended ("CERCLA" or
"Superfund"), all primarily administered by the United States Environmental
Protection Agency ("EPA"). The hazardous waste management business is heavily
dependent upon the extent to which regulations promulgated under these or
similar state statutes and their enforcement over time effectively require
wastes to be specially handled or managed and disposed of in facilities of the
type owned and operated by the Company. See "Regulation--Waste Management
Services--Hazardous Waste," "--RCRA" and "--Superfund." The chemical waste
services industry currently has substantial excess capacity caused by a number
of factors, including a decline in environmental remediation projects
generating hazardous waste for off-site treatment and disposal, continuing
efforts by hazardous waste generators to reduce volume and to manage the wastes
on-site, and the uncertain regulatory environment regarding hazardous waste
management and remediation requirements. These factors have led to reduced
demand and increased pressure on pricing for chemical waste management
services, conditions which the Company expects to continue for the foreseeable
future.
 
LOW-LEVEL AND OTHER RADIOACTIVE WASTE SERVICES
 
  Radioactive wastes with varying degrees of radioactivity are generated by
nuclear reactors and by medical, industrial, research and governmental users of
radioactive material. Radioactive wastes are generally classified as either
high-level or low-level. High-level radioactive waste, such as spent nuclear
fuel and waste generated during the reprocessing of spent fuel from nuclear
reactors, contains substantial quantities of long-lived radionuclides and is
the ultimate responsibility of the federal government. Low-level radioactive
waste, which decays more quickly than high-level waste, largely consists of dry
compressible wastes (such as contaminated gloves, paper, tools and clothing),
resins and filters which have removed radioactive contaminants from nuclear
reactor cooling water, solidified wastes from power plants which have become
contaminated with radioactive substances and irradiated hardware.
 
  Chem-Nuclear provides comprehensive low-level radioactive waste management
services in the United States consisting of disposal, processing and various
other special services. To a lesser extent, it provides services with respect
to radioactive waste that has become mixed with regulated chemical waste.
 
 
                                       8
<PAGE>
 
  Chem-Nuclear's radioactive disposal operations involve primarily low-level
radioactive waste. Its Barnwell, South Carolina facility, which has been in
operation since 1971, is one of three licensed commercial low-level
radioactive waste disposal facilities in the United States. A trust has been
established and funded to pay the estimated cost of decommissioning the
Barnwell facility. A second fund, for the extended care of the facility, is
funded by a surcharge on each cubic foot of waste received. Chem-Nuclear may
be liable for additional costs if the extra charges collected to restore and
maintain the facility are insufficient to cover the cost of restoring or
maintaining the site after its closure. The Company does not expect this to
have a material adverse impact on future operating results.
 
  Under state legislation enacted in 1995, the Barnwell site is authorized to
operate until its current permitted disposal capacity is fully utilized.
However, that legislation was attached to a state appropriations bill that
included a provision for a state tax of $235 to be imposed on every cubic foot
of waste disposed of at the Barnwell facility. As a result of decreased
disposal volume and a shortfall in anticipated tax revenue, in June 1997, the
State of South Carolina enacted new legislation requiring that Chem-Nuclear
guarantee certain portions of anticipated tax revenues from the facility. Such
reduced disposal volume and the requirement that Chem-Nuclear fund such tax
payments have caused Chem-Nuclear to review its alternatives with respect to
the Barnwell facility. If Chem-Nuclear determines to close the Barnwell site,
the Company's earnings for one or more fiscal quarters or years could be
adversely affected.
 
  Chem-Nuclear also processes low-level radioactive waste at its customers'
plants to enable such waste to be shipped in dry rather than liquid form to
meet the requirements for receipt at disposal facilities and to reduce the
volume of waste that must be transported. Processing operations include
solidification, demineralization, dewatering and filtration. Other services
offered by Chem-Nuclear include providing electro-chemical, abrasive and
chemical removal of radioactive contamination, providing management services
for spent nuclear fuel storage pools and storing and incinerating liquid
radioactive organic wastes.
 
INTERNATIONAL WASTE MANAGEMENT AND RELATED SERVICES
 
  The Company is a leading provider of waste management and related services
internationally, primarily through WM International, which conducts
essentially all of the waste management operations of the Company located
outside North America. International waste management and related services
comprised approximately 20.0%, 20.5%, 20.7% and 19.5% of the Company's total
revenue in each of the four years ended December 31, 1994, 1995, 1996 and
1997. WM International's business may broadly be characterized into two areas
of activity, collection services and treatment and disposal services. The
following table shows the derivation of WM International's revenue for the
years indicated and includes revenue from construction of treatment or
disposal facilities for third parties under "Treatment and Disposal Services":

</TABLE>
 
  While the Company has had international operations since the mid-1970's, the
bulk of the Company's international operations and revenues are derived from
the acquisition from 1990 to 1995 of numerous companies and interests in
Europe. However, with its acquisition goals largely completed, WM
International has engaged in only a few small acquisitions since 1995 and has
begun to dispose of certain operations which do not fit within its long-term
strategy.
 
  In accordance with its objective of maintaining a local identity, WM
International, in certain cases, operates through companies or joint ventures
in which WM International and its affiliates own less than a 100% interest.
For example, WM International is a party to a joint venture with Wessex to
provide waste management and related services in the United Kingdom.
 
                                       9
<PAGE>
 
  WM International's revenue mix by country varies from year to year.
Countries in which revenue exceeded 10% of WM International's consolidated
total were: Italy (26%) and Germany (12%) in 1994; Italy (23%), Germany (14%),
the Netherlands (11%) and the United Kingdom (11%) in 1995; Italy (25%), the
United Kingdom (12%), Germany (11%) and the Netherlands (11%) in 1996; and
Italy (25%), the United Kingdom (15%) and the Netherlands (11%) in 1997.
 
  While WM International has considerable experience in mobilizing for and
managing foreign projects, its operations continue to be subject generally to
such risks as currency fluctuations and exchange controls, the need to recruit
and retain suitable local labor forces and to control and coordinate
operations in different jurisdictions, changes in foreign laws or governmental
policies or attitudes concerning their enforcement, political changes, local
economic conditions and international tensions. In addition, price adjustment
provisions based on certain formulae or indices may not accurately reflect the
actual impact of inflation on the cost of performance.
 
  During 1997, the Company sold all of its operations in France and Spain and
certain other businesses in Germany and Austria. In addition, in January 1998
the Company sold its waste-to-energy facility located in Hamm, Germany. See
"--Treatment and Disposal Services" below.
 
COLLECTION SERVICES
 
  Collection services include collection and transportation of solid,
hazardous and medical wastes and recyclable material from residential,
commercial and industrial customers. Street, industrial premises, office and
parking lot cleaning services are also performed by WM International, along
with portable sanitation/toilet services for occasions such as outdoor
concerts and special events. The residential solid waste collection process,
as well as the commercial and industrial solid and hazardous waste collection
process, is similar to that utilized by the Company in the United States.
Business is obtained through public bids or tenders, negotiated contracts,
and, in the case of commercial and industrial customers, direct contracts.
 
  Residential solid waste collection is typically performed by WM
International pursuant to municipal contracts. At December 31, 1997, WM
International had approximately 1,540 municipal contracts, serving more than
4.8 million residential properties. The scope, specifications, services
provided and duration of such contracts vary substantially, with some
contracts encompassing landfill disposal of collected waste, street sweeping
and other related municipal services. The largest number of municipal
contracts held by WM International is in Italy where WM International services
approximately 1.7 million residential properties. Pricing for municipal
contracts is generally based on volume of waste, number and frequency of
collection pick-ups, and disposal arrangements. Longer-term contracts
typically have formulae for periodic price increases or adjustments. WM
International also provides curbside recycling services similar to those
provided by WMNA in North America.
 
  WM International's commercial and industrial solid and hazardous waste
collection services are generally contracted for by individual establishments.
In addition to solid waste collection customers, WM International provides
services to small quantity waste generators, as well as larger petrochemical,
pharmaceutical and other industrial customers, including collection of
hazardous, chemical or medical wastes or residues. WM International has
approximately 293,000 commercial and industrial customers. Contract terms and
prices vary substantially among jurisdictions and types of customer. WM
International also provides commercial and industrial recycling services.
 
TREATMENT AND DISPOSAL SERVICES
 
  Treatment and disposal services include processing of recyclable materials,
operation of both solid and hazardous waste landfills, operation of municipal
and hazardous waste incinerators, operation of water and wastewater treatment
facilities, operation of hazardous waste treatment facilities and construction
of treatment or disposal facilities for third parties. Treatment and disposal
services are provided under contracts which may be obtained through public bid
or tender or direct negotiation, and are also provided directly to other waste
service companies.
 
                                      10
<PAGE>
 
  Once collected, solid wastes may be processed in a recyclables processing
facility for sale or other disposition for use in various applications.
Unprocessed solid wastes, or the portion of the waste stream remaining after
recovery of recyclable materials, require disposal, which may be accomplished
through incineration (in connection with which the energy value may be
recovered in a trash-to-energy facility) or through disposal in a solid waste
landfill. The relative use of landfills versus incinerators differs from
country to country and will depend on many factors, including the availability
of land, geological and hydrological conditions, the availability and cost of
technology and capital, and the regulatory environment. The main determinants
of the disposal method are the disposal costs at local landfills, as
incineration is generally more expensive, community preferences and regulatory
provisions.
 
  At present, in most countries in which WM International operates,
landfilling is the predominant disposal method employed. WM International owns
or operates solid waste landfills in Argentina, Australia, Brazil, Denmark,
Germany, Hong Kong, Italy, New Zealand, Sweden and the United Kingdom.
Landfill disposal agreements may be separate contracts or an integrated
portion of collection or treatment contracts.
 
  Demand for solid waste incineration is affected primarily by landfill
disposal costs, government regulations and, increasingly, public perception
issues. The incineration process for non-hazardous solid waste has also been
influenced by two significant factors in recent years: (i) increasingly strict
control over air emissions from incinerators; and (ii) increasing emphasis on
trash-to-energy incinerators, which utilize heat produced by incinerators to
generate electricity and other energy. Incineration generates approximately
30% residue (by weight), which is either landfilled or, if permitted, recycled
for use as a road base or in other construction uses.
 
  Prior to January 1998, WM International operated a waste-to-energy
incinerator in Hamm, Germany. In light of the current overcapacity in the
German waste-to-energy market and the pending renegotiation of WM
International's disposal contracts with the local communities, WM
International entered into an agreement in April 1997 to sell the facility.
The transaction was completed in January 1998. Revenues from the Hamm facility
accounted for approximately 2% of WM International's 1997 consolidated
revenue. See "Management's Discussion and Analysis of Results of Operations
and Financial Condition--Results of Operations."
 
  In 1992, WM International entered into a contract with the County of
Gutersloh, Germany to design, construct, own and operate a trash-to-energy
facility. The facility is designed to convert 268,000 metric tons per year of
municipal waste and sewage sludge into energy. During 1995, WM International's
permit application to develop and operate the Gutersloh facility was denied.
WM International appealed the denial through the German administrative court
system. Throughout 1996 and 1997, WM International and the County of Gutersloh
engaged in discussions regarding the future viability of the proposed project
as well as the County of Gutersloh's right to terminate the 25-year operating
agreement and the lease agreement covering the site on which the plant is to
be constructed. In 1997, the County exercised its right to terminate the lease
agreement for the plant site, effectively terminating the permitting process
and the pending administrative court proceedings. The County has also
informally indicated its intention to terminate WM International's operating
agreement. As a result of the termination of the lease agreement and the
threatened termination of the operating agreement, WM International reserved
the full amount of its unamortized development cost in the project as a part
of the special charge recorded in the fourth quarter of 1997. WM International
is assessing its options to seek redress against the County of Gutersloh and
against state permitting authorities, but no assurances can be given that it
will be successful in obtaining damages in respect of the project.
 
  WM International also operates five small, conventional municipal solid and
other waste incineration facilities. WM International and WTI have also formed
a joint venture to develop trash-to-energy projects outside Germany, Italy and
North America. See "Competition" below.
 
  WM International owns or operates hazardous waste treatment facilities in
Brazil, Brunei, Finland, Germany, Hong Kong, Indonesia, Italy, the
Netherlands, Sweden and the United Kingdom.

TRASH-TO-ENERGY AND RELATED SERVICES
 
  WTI, through its subsidiaries, is a leading developer, operator and owner of
trash-to-energy and waste fuel powered independent power facilities in the
United States. These facilities, either owned or operated, give WTI
approximately 920 megawatts per hour of electric generating capacity. WTI's
trash-to-energy projects utilize proven boiler and grate technology and are
capable of processing up to 23,750 tons of solid waste per day. The heat from
this combustion process is converted into high-pressure steam, which typically
is used to generate electricity for sale to public utility companies under
long-term contracts.
 
  WTI's trash-to-energy development activities have historically involved a
number of contractual arrangements with a variety of private and public
entities, including municipalities (which supply trash for combustion),
utilities or other power users (which purchase the energy produced by the
facility), lenders, public debtholders, joint venture partners and equity
investors (which provide financing for the project) and the contractors or
subcontractors responsible for building the facility. In addition, WTI's
activities have often included identifying and acquiring sites for the
facility and for the disposal of residual ash produced by the facility and
obtaining necessary permits and licenses from local, state and federal
regulatory authorities.
 
  WTI also develops, operates and, in some cases, owns independent power
projects, which either cogenerate electricity and thermal energy or generate
electricity alone for sale to customers, including utilities and private
industry. Cogeneration is a technology which allows the simultaneous
production of two or more useful forms of energy from a single primary fuel
source, thus providing a more efficient use of a fuel's total energy content.
These power systems use waste wood, waste tires, waste coal or natural gas as
fuel, and employ state-of-the-art technology, such as fluidized-bed
combustion, to ensure the efficient burning of fuel with reduced emission
levels.
 
  In addition, WTI develops, operates and owns projects that compost organic
wastes and treat and manage biosolids. WTI provides a range of biosolids
management services, including land application, drying, pelletizing, alkaline
stabilization and composting, to more than 275 communities, typically pursuant
to multi-year contracts under which WTI is paid by the generator to make
beneficial use of the biosolids. Land application involves the application of
non-hazardous biosolids as a natural fertilizer on farmland pursuant to
rigorous site-specific permits issued by applicable state authorities.
Biosolids are also used in land reclamation projects such as strip mines.
Regulations issued by the EPA in December 1992 under the Clean Water Act
encourage the beneficial use of municipal sewage sludge by recognizing the
resource value of biosolids as a fertilizer and soil conditioner, and
establish requirements for land application designed to protect human health
and the environment.
 
  WTI also develops and operates facilities at which biosolids are dried and
pelletized and has three facilities currently in operation, with one other
facility undergoing start-up activity. WTI has approximately 536 dry-tons-per-
day of biosolids drying capacity in operation. Biosolids which have been dried
are generally used as fertilizer by farmers, commercial landscapers and
nurseries and as a bulking agent by fertilizer manufacturers.
 
  WTI subsidiaries also design and install advanced air pollution control
equipment and design, construct and maintain tall concrete chimneys and
storage silos. WTI's expertise in air pollution control technologies and
chimney design and construction is used in the design and construction of
WTI's trash-to-energy facilities, which WTI believes strengthens its
competitive position.
 
REGULATION
 
GENERAL
 
  While, in general, the Company's waste management services business has
benefited from increased governmental regulation, the industry in which the
Company operates has become subject to extensive and evolving regulation by
federal, state, local and foreign authorities. In particular, the regulatory
process requires firms in the Company's industry to obtain and retain numerous
governmental permits to conduct various aspects
 
                                      12
<PAGE>
 
of their operations, any of which may be subject to revocation, modification
or denial. As a result of governmental policies and attitudes relating to the
industry, which are subject to reassessment and change, the Company believes
that its ability to obtain applicable permits from governmental authorities on
a timely basis, and to retain such permits, could become impaired. The Company
is not in a position at the present time to assess the extent of the impact of
such potential changes in governmental policies and attitudes on the
permitting processes, but it could be significant. In particular, adverse
decisions by governmental authorities on permit applications submitted by the
Company may result in abandonment of projects, premature closure of facilities
or restriction of operations, which could result in a loss of earnings from a
facility, a write-off of capitalized costs or both.
 
  Federal, state, local and foreign governments have also from time to time
proposed or adopted other types of laws, regulations or initiatives with
respect to the waste management services industry. Included among them are
laws, regulations and initiatives to ban or restrict the international,
interstate or intrastate shipment of wastes, impose higher taxes on out-of-
state waste shipments than in-state shipments, reclassify certain categories
of hazardous wastes as non-hazardous and regulate disposal facilities as
public utilities. Certain state and local governments have promulgated "flow
control" regulations, which attempt to require that all waste generated within
the state or local jurisdiction must go to certain disposal sites. The United
States Congress has from time to time considered legislation that would enable
or facilitate such bans, restrictions, taxes and regulations. Due to the
complexity of regulation of the industry and to public pressure,
implementation of existing or future laws, regulations or initiatives by
different levels of government may be inconsistent and is difficult to
foresee. Many state and local governments have enacted mandatory or voluntary
recycling laws and bans on the disposal of yard-waste in landfills. An effect
of these and similar laws is to reduce the volume of wastes that would
otherwise be disposed in landfills. In addition, municipalities and other
governmental entities with whom the Company contracts to provide solid waste
collection or disposal services, or both, may require the Company as a
condition of securing the business to provide recycling services and operate
recycling and composting facilities, which may cause the Company to incur
substantial costs. The Company makes a continuing effort to anticipate
regulatory, political and legal developments that might affect its operations
but is not always able to do so. The Company cannot predict the extent to
which any legislation or regulation that may be enacted, amended, repealed or
enforced, or any failure or delay in enactment or enforcement of legislation
or regulations or funding of government agencies or programs, in the future
may affect its operations. Such matters could have a material adverse impact
on the Company's earnings for one or more fiscal quarters or years.
 
  The demand for certain of the services provided by the Company, particularly
its hazardous waste management services, is dependent in part on the existence
and enforcement of federal, state and foreign laws and regulations which
govern the discharge of hazardous substances into the environment and on the
funding of agencies and programs under such laws and regulations. Such
businesses will be adversely affected to the extent that such laws or
regulations are amended or repealed, with the effect of reducing the
regulation of, or liability for, such activity, that the enforcement of such
laws and regulations is lessened or that funding of agencies and programs
under such laws and regulations is delayed or reduced. In particular, the EPA
continues to consider proposals under RCRA to redefine the term "hazardous
waste" for regulatory purposes. Under some such proposals, wastes containing
minimal concentrations of hazardous substances would no longer be subject to
the stringent record-keeping, handling, treatment and disposal rules applied
to hazardous wastes under RCRA. Other EPA proposals would cause certain wastes
which presently must be managed in TSCA-approved facilities to be eligible for
disposal in facilities not approved under TSCA. These proposals would, if
adopted, reduce the volume of wastes for which the Company's hazardous waste
management services are needed.
 
  In addition to environmental laws and regulations, federal government
contractors, including the Company, are subject to extensive regulation under
the Federal Acquisition Regulation and numerous statutes which deal with the
accuracy of cost and pricing information furnished to the government, the
allowability of costs charged to the government, the conditions under which
contracts may be modified or terminated, and other similar matters. Various
aspects of the Company's operations are subject to audit by agencies of the
federal government in connection with its performance of work under such
contracts as well as its submission of bids or proposals to
 
                                      13
<PAGE>
 
the government. Failure to comply with contract provisions or other applicable
requirements may result in termination of the contract, the imposition of
civil and criminal penalties against the Company, or the suspension or
debarment of all or a part of the Company from federal government work, which
could have a material adverse impact upon the Company's financial condition or
earnings for one or more fiscal quarters or years. Among the reasons for
debarment are violations of various statutes, including those related to
employment practices, the protection of the environment, the accuracy of
records and the recording of costs. Some state and local governments have
similar suspension and debarment laws or regulations.
 
  Because of the high level of public awareness of environmental issues,
companies in the waste management services business, including the Company,
may in the normal course of their business be expected periodically to become
subject to judicial and administrative proceedings. Governmental agencies may
seek to impose fines on the Company or revoke, deny renewal of, or modify the
Company's operating permits or licenses. The Company is also subject to
actions brought by private parties or special interest groups in connection
with the permitting or licensing of its operations, alleging violations of
such permits and licenses, or other matters. In addition, increasing
governmental scrutiny of the environmental compliance records of the Company,
CWM, WTI, Rust, WM International or their affiliates could cause a private or
public entity seeking waste management services to disqualify the Company from
competing for one or more projects, on the grounds that these records display
inadequate attention to environmental compliance.
 
WASTE MANAGEMENT SERVICES
 
SOLID WASTE
 
  Operating permits are generally required at the state and local level for
landfills, transfer stations and collection vehicles. Operating permits need
to be renewed periodically and may be subject to revocation, modification,
denial or non-renewal for various reasons, including failure of the Company to
satisfy regulatory concerns. With respect to solid waste collection,
regulation takes such forms as licensing of collection vehicles, truck safety
requirements, vehicular weight limitations and, in certain localities,
limitations on rates, area, time and frequency of collection. With respect to
solid waste disposal, regulation covers various matters, including landfill
location and design, groundwater monitoring, gas control, liquid runoff and
rodent, pest, litter and traffic control. Zoning and land use requirements and
limitations are encountered in the solid waste collection, transfer, recycling
and energy recovery and disposal phases of the Company's business. In almost
all cases the Company is required to obtain conditional use permits or zoning
law changes in order to develop transfer station, resource recovery or
disposal facilities. In addition, the Company's disposal facilities are
subject to water and air pollution laws and regulations. Noise pollution laws
and regulations may also affect the Company's operations. Governmental
authorities have the power to enforce compliance with these various laws and
regulations and violators are subject to injunctions, fines and revocation of
permits. Private individuals may also have the right to sue to enforce
compliance. Safety standards under the Occupational Safety and Health Act
("OSHA") are also applicable to the Company's solid waste and related services
operations.
 
  The EPA and various states acting pursuant to EPA-delegated authority have
promulgated rules pursuant to RCRA which serve as minimum requirements for
land disposal of municipal wastes. The rules establish more stringent
requirements than previously applied to the siting, construction, operations,
closure and post-closure monitoring and maintenance of all but the smallest
municipal waste landfill facilities. In certain cases, the failure of some
states to adopt the federal requirements may increase costs to meet
inconsistent federal and state laws applicable to the same facility. The
Company does not believe that continued compliance with the more stringent
minimum requirements will have a material adverse effect on the Company's
operations. See also "RCRA" and "Superfund" below for additional regulatory
information.
 
  In March 1996, the EPA issued regulations that require large, municipal
solid waste landfills to install and monitor systems to collect and control
landfill gas. The regulations apply to landfills that are designed to
accommodate 2.5 million cubic meters or more of municipal solid waste and that
accepted waste for disposal after November 8, 1987, regardless of whether the
site is active or closed. The date by which each affected
 
                                      14
<PAGE>
 
landfill must have such a gas collection and control system depends on whether
the landfill began operation before or after May 30, 1991. Landfills
constructed, reconstructed, modified or first accepting waste after May 30,
1991 generally must have systems in place by late 1998. Older landfills
generally will be regulated by the states and will be required to have landfill
gas systems in place within approximately 30 months of EPA's approval of the
state program. Many state solid waste regulations already require collection
and control systems. Compliance with the new regulations is not expected to
have a material adverse effect on the Company.
 
HAZARDOUS WASTE
 
  WMNA and CWM are required to obtain federal, state, local and foreign
governmental permits for their chemical waste treatment, storage and disposal
facilities. Such permits are difficult to obtain, and in most instances
extensive geological studies, tests and public hearings are required before
permits may be issued. WMNA's and CWM's chemical waste treatment, storage and
disposal facilities are also subject to siting, zoning and land use
restrictions, as well as to regulations (including certain requirements
pursuant to federal statutes) which may govern operating procedures and water
and air pollution, among other matters. In particular, WMNA's and CWM's
operations in the United States are subject to the Safe Drinking Water Act
(which regulates deep well injection), TSCA (pursuant to which the EPA has
promulgated regulations concerning the disposal of PCBs), the Clean Water Act
(which regulates the discharge of pollutants into surface waters and sewers by
municipal, industrial and other sources) and the Clean Air Act (which regulates
emissions into the air of certain potentially harmful substances). In their
transportation operations, WMNA and CWM are subject to the jurisdiction of the
Interstate Commerce Commission and regulated by the DOT and by regulatory
agencies in each state. Employee safety and health standards under OSHA are
also applicable.
 
  All of WMNA's and CWM's chemical waste treatment or disposal facilities in
the United States have been issued permits under RCRA. The regulations
governing issuance of permits contain detailed standards for hazardous waste
facilities on matters such as construction, waste analysis, security,
inspections, training, preparedness and prevention, emergency procedures,
reporting and recordkeeping, closure and post-closure monitoring and
maintenance. Once issued, a final permit has a maximum fixed term of 10 years,
and such permits for land disposal facilities are required to be reviewed five
years from the date of issuance. The issuing agency (either the EPA or an
authorized state) may review or modify a permit at any time during its term.
 
  The Company believes that WMNA and CWM maintain each of their operating
treatment, storage or disposal facilities in substantial compliance with the
applicable requirements promulgated pursuant to RCRA. It is possible, however,
that the issuance or renewal of a permit could be made conditional upon the
initiation or completion of modifications or corrective actions at facilities,
which might involve substantial additional capital expenditures on the part of
WMNA or CWM. Although the Company is informed that WMNA and CWM anticipate the
reauthorization of each permit at the end of its term if the facility's
operations are in compliance with applicable requirements, there can be no
assurance that such will be the case.
 
  The radioactive waste services of Chem-Nuclear are also subject to extensive
governmental regulation. Due to the extensive geological and hydrological
testing and environmental data required, and the complex political environment,
it is difficult to obtain permits for radioactive waste disposal facilities.
Various phases of Chem-Nuclear's low-level radioactive waste management
services are regulated by various state agencies, the United States Nuclear
Regulatory Commission (the "NRC") and the DOT. Regulations applicable to Chem-
Nuclear's operations include those dealing with packaging, handling, labeling
and routing of radioactive materials, and prescribe detailed safety and
equipment standards and requirements for training, quality control and
insurance, among other matters. Employee safety and health standards under OSHA
are also applicable.
 
  See also "RCRA" and "Superfund" below for additional regulatory information.
 
TRASH-TO-ENERGY AND RELATED SERVICES
 
  WTI's business activities are subject to environmental regulation under
federal, state and local laws and regulations, including the Clean Air Act, the
Clean Water Act and RCRA. The Company believes that WTI's
 
                                       15
<PAGE>
 
business is conducted in an environmentally responsible manner in material
compliance with applicable laws and regulations. The Company does not
anticipate that WTI's maintaining compliance with current requirements will
result in any material decrease in earnings. There can be no assurance,
however, that such requirements will not change so as to require significant
additional expenditures. In particular, within the next several years, the air
pollution control systems at certain trash-to-energy facilities owned or
leased by WTI most likely will be required to be modified to comply with more
stringent air pollution control standards adopted by the EPA in December 1995
for municipal waste combusters. The compliance dates will vary by facility,
but all affected facilities most likely will be required to be in compliance
with the standards by the end of the year 2000. Currently available
technologies are adequate to meet the new standards. Although the total
expenditures required for such modifications are estimated to be $180 million
to $220 million, they are not expected to have a material adverse effect on
the Company's liquidity or results of operations because provisions in the
impacted facilities' long-term waste supply agreements generally allow WTI to
recover from customers the majority of incremental capital and operating
costs. Customer shares of capital and financing costs are typically recovered
over the remaining life of the waste supply agreements, and pro rata operating
costs are recovered in the period incurred. There can be no assurance,
however, that in such event WTI would be able to recover, for each project,
all such increased costs from its customers. Moreover, it is possible that
future developments, such as increasingly strict requirements of environmental
laws, and enforcement policies thereunder, could affect the manner in which
WTI operates its projects and conducts its business, including the handling,
processing or disposal of the wastes, by-products and residues generated
thereby.
 
  Also, in May 1994, the U.S. Supreme Court ruled that state and local
governments may not constitutionally restrict the free movement of trash in
interstate commerce through the use of flow control laws. Such laws typically
involve a local government specifying a jurisdictional disposal site for all
solid waste generated within its borders. Since the ruling, several decisions
of state or federal courts have invalidated regulatory flow control schemes in
a number of jurisdictions. Other judicial decisions have upheld non-regulatory
means by which municipalities may effectively control the flow of municipal
solid waste. In addition, federal legislation has been proposed, but not yet
enacted, to effectively grandfather existing flow control mandates. There can
be no assurance that such alternatives to regulatory flow control will in
every case be found lawful or that such legislation will be enacted into law.
 
  WTI's Gloucester County, New Jersey facility has historically relied on a
disposal franchise for substantially all of its supply of municipal solid
waste. On May 1, 1997, the Third Circuit Court of Appeals (the "Third
Circuit") permanently enjoined the State of New Jersey from enforcing its
franchise system as a form of unconstitutional solid waste flow control, but
stayed the injunction for so long as any appeals were pending. On November 10,
1997, the United States Supreme Court announced its decision not to review the
Third Circuit decision, thereby ending the stay and, effectively, the
facility's disposal franchise. The State had continued to enforce flow control
during the stay period. In response, the Gloucester facility has lowered its
prices and solicited new customers.
 
  Under the reimbursement agreement between the project company that owns the
Gloucester facility and the bank that provides credit support to the project,
the termination of the waste franchise constitutes an event of default. WTI
and the credit support bank are presently discussing the consequences of these
developments.
 
  The New Jersey legislature has been considering various legislative
solutions, including a bill that provides for the payment and recovery of
bonded indebtedness incurred by counties, public authorities and certain
qualified private vendors in reliance on the state's franchise system. The
Company currently believes that, through either legislative action or a
project recapitalization, the Gloucester project can be restructured to
operate profitably, albeit at reduced levels, in the absence of regulatory
flow control.
 
  The Supreme Court's 1994 ruling and subsequent court decisions have not to
date had a material adverse effect on any of WTI's trash-to-energy operations.
Federal legislation has been proposed, but not yet enacted, to effectively
grandfather existing flow control mandates. In the event that such legislation
is not adopted, WTI believes that affected municipalities will endeavor to
implement alternative lawful means to continue controlling
 
                                      16
<PAGE>
 
the flow of waste. In view of the uncertain state of the law at this time,
however, WTI is unable to predict whether such efforts would be successful or
what impact, if any, this matter might have on WTI's trash-to-energy
facilities.
 
  WTI's energy facilities are also subject to the provisions of various energy-
related laws and regulations, including the Public Utility Regulatory Policies
Act of 1978 ("PURPA"). The ability of WTI's trash-to-energy and small power
production facilities to sell power to electric utilities on advantageous terms
and conditions and to avoid burdensome public utility regulation has
historically depended, in part, upon the applicability of certain provisions of
PURPA, which generally exempts WTI from state and federal regulatory control
over electricity prices charged by, and the finances of, WTI and its energy-
producing subsidiaries. As state legislatures and the United States Congress
have accelerated their consideration of the manner in which economic
efficiencies can be gained by deregulating the electric generation industry,
utilities and others have taken the position that power sales agreements
entered into pursuant to PURPA which provide for rates in excess of current
market rates should be voidable as "stranded assets." WTI's power production
facilities are qualifying facilities under PURPA and depend on the sanctity of
their power sales agreements for their economic viability. Although a repeal or
modification of PURPA is possible within the next two years, WTI believes that
federal law offers strong protection to the PURPA contracts and recent state
and federal agency and court decisions have unanimously upheld the inviolate
nature of these contracts. In addition, state legislative actions to date have
not attempted to abrogate these contracts. While there is some risk that future
utility restructurings, court decisions and/or legislative or administrative
action in this area could have an adverse effect on the business of WTI, in
light of recent developments, WTI currently believes such risk is remote. The
operations of WTI's existing trash-to-energy and other small power production
facilities business are not currently expected to be materially and adversely
affected if the various benefits of PURPA are repealed or substantially reduced
on a prospective basis.
 
  Finally, the passage of the Energy Policy Act of 1992 created an alternative
ownership mechanism by which WTI's future independent power projects would be
able to participate in the electricity generation industry without the burdens
of traditional public utility regulation. However, WTI can give no assurances
that future utility restructurings, court decisions or legislative or
administrative action in this area will not have a material adverse impact on
WTI's financial position or results of operations.
 
RCRA
 
  Pursuant to RCRA, the EPA has established and administers a comprehensive,
"cradle-to-grave" system for the management of a wide range of industrial by-
products and residues identified as "hazardous" wastes. States that have
adopted hazardous waste management programs with standards at least as
stringent as those promulgated by the EPA may be authorized by the EPA to
administer their programs in lieu of RCRA.
 
  Under RCRA and federal transportation laws, a transporter must deliver
hazardous waste in accordance with a manifest prepared by the generator of the
waste and only to a treatment, storage or disposal facility having a RCRA
permit or interim status under RCRA. Every facility that treats or disposes of
hazardous wastes must obtain a RCRA permit from the EPA or an authorized state
and must comply with certain operating standards. The RCRA permitting process
involves applying for interim status and also for a final permit. Under RCRA
and the implementing regulations, facilities which have obtained interim status
are allowed to continue operating by complying with certain minimum standards
pending issuance of a permit.
 
  RCRA also imposes restrictions on land disposal of certain hazardous wastes
and prescribes standards for hazardous waste land disposal facilities. Under
RCRA, land disposal of certain types of untreated hazardous wastes has been
banned except where the EPA has determined that land disposal of such wastes
and treatment residuals should be permitted. The disposal of liquids in
hazardous waste land disposal facilities is also prohibited.
 
  The EPA from time to time considers fundamental changes to its regulations
under RCRA that could facilitate exemptions from hazardous waste management
requirements, including policies and regulations that
 
                                       17
<PAGE>
 
could implement the following changes: redefine the criteria for determining
whether wastes are hazardous; prescribe treatment levels which, if achieved,
could render wastes non-hazardous; encourage further recycling and waste
minimization; reduce treatment requirements for certain wastes to encourage
alternatives to incineration; establish new operating standards for combustion
technologies; and indirectly encourage on-site remediation. To the extent such
changes are adopted, they can be expected to adversely affect the demand for
the Company's chemical waste management services. In this regard, the EPA has
recently proposed regulations which would have the effect of reducing the
volume of waste classified as hazardous for RCRA regulatory purposes. See
"Regulation--General--Waste Management Services--Hazardous Waste."
 
  In addition to the foregoing provisions, RCRA regulations require the
Company to demonstrate financial responsibility for possible bodily injury and
property damage to third parties caused by both sudden and nonsudden
accidental occurrences. See "Insurance." Also, RCRA regulations require the
Company to provide financial assurance that funds will be available when
needed for closure and post-closure care at its waste treatment, storage and
disposal facilities, the costs of which could be substantial. Such regulations
allow the financial assurance requirements to be satisfied by various means,
including letters of credit, surety bonds, trust funds, a financial (net
worth) test and a guarantee by a parent corporation. Under RCRA regulations, a
company must pay the closure costs for a waste treatment, storage or disposal
facility owned by it upon the closure of the facility and thereafter pay post-
closure care costs. If such a facility is closed prior to its originally
anticipated time, it is unlikely that sufficient funds or reserves will have
been accrued over the life of the facility to provide for such costs, and the
owner of the facility could suffer a material adverse impact as a result.
Consequently, it may be difficult to close such facilities to reduce operating
costs at times when, as is currently the case in the hazardous waste services
industry, excess treatment, storage or disposal capacity exists.
 
SUPERFUND
 
  Superfund provides for EPA-coordinated response and removal actions to
releases of hazardous substances into the environment, and authorizes the
federal government either to clean up facilities at which hazardous substances
have created actual or potential environmental hazards or to order persons
responsible for the situation to do so. Superfund assigns liability for these
response and other related costs to parties involved in the generation,
transfer and disposal of such hazardous substances. Superfund has been
interpreted as creating strict, joint and several liability for costs of
removal and remediation, other necessary response costs and damage to natural
resources. Liability extends to owners and operators of waste disposal
facilities (and waste transportation vehicles) from which a release occurs,
persons who owned or operated such facilities at the time the hazardous
substances were disposed, persons who arranged for disposal or treatment of a
hazardous substance at or transportation of a hazardous substance to such a
facility, and waste transporters who selected such facilities for treatment or
disposal of hazardous substances. Liability may be trebled if the responsible
party fails to perform a removal or remedial action ordered under the law. For
additional information concerning potential Superfund liability, see "Legal
Proceedings."
 
  Superfund created a revolving fund to be used by the federal government to
pay for the cleanup efforts. For the federal government's 1997 fiscal year, a
maximum of approximately $1.4 billion of Superfund spending was authorized.
The federal government has also approved approximately the same amount of 1998
Superfund spending authorization.
 
  The U. S. Congress is expected to consider reauthorization and revision of
the Superfund statute in 1998. In addition to possible changes in the
statute's funding mechanisms and provisions for allocating cleanup
responsibility, it is possible that Congress also will fundamentally alter the
statute's provisions governing the selection of appropriate site cleanup
remedies. For example, Congress may consider whether to continue Superfund's
current reliance on stringent technology standards issued under other statutes
(such as RCRA) to govern removal and treatment of remediation wastes or to
adopt new approaches such as national or site-specific risk based standards.
This and other potential policy changes could significantly affect the
stringency and extent of site remediation, the types of remediation techniques
that will be employed, and the degree to which permitted
 
                                      18
<PAGE>
 
hazardous waste management facilities will be used for remediation wastes. In
addition, Congress may consider revision of the liability imposed by the
Superfund law for remediation of contamination caused prior to a party's
acquisition of a contaminated site, which could reduce the remediation
obligations of the Company and others who currently are jointly and severally
liable for remediation obligations under Superfund.
 
INTERNATIONAL WASTE MANAGEMENT AND RELATED SERVICES
 
  WM International's operations are subject to the general business, liability,
land-use planning and other environmental laws and regulations of the countries
where the services are performed and, in Europe, to European Union ("EU")
regulations and directives. The degree of local enforcement of applicable laws
and regulations varies substantially between, and even within, the various
countries in which WM International operates. In addition to the statutes and
regulations imposed by national, state or provincial, and municipal or other
local authorities, many of the countries in which WM International operates are
members of the EU. The EU has issued and continues to issue environmental
directives and regulations covering a broad range of environmental matters and
has created a European Environmental Agency responsible for monitoring and
collating member state environmental data. The Single European Act, passed in
1987, established three fundamental principles to guide the development of
future EU environmental law: (i) the need for preventative action; (ii) the
correction of environmental problems at the source; and (iii) the polluter's
liability for environmental damage.
 
  The Treaty on European Union, signed in December 1991, came into force in
November 1993. Revised in Amsterdam in June 1997, the Treaty now regards
"sustainable development" as a key component of EU policy-making and requires
that environmental protection be integrated into the definition and application
of all EU laws.
 
  The impact of current and future EU legislation will vary from country to
country according to the degree to which existing national requirements already
meet or fall short of the new EU standards and, in some jurisdictions, may
require extensive public and private sector investment and the development and
provision of the necessary technology, expertise, administrative procedures and
regulatory structures. These extensive laws and regulations are continually
evolving in response to technological advances and heightened public and
political concern.
 
  Outside Europe, continuing industrialization, population expansion and
urbanization have caused increased levels of pollution with all of the
resultant social and economic implications. The desire to sustain economic
growth and address historical pollution problems is being accompanied by
investments in environmental infrastructure, particularly in Southeast Asia,
and the introduction of regulatory standards to further control industrial
activities.
 
  The Company believes that WM International's business is conducted in
material compliance with applicable laws and regulations and does not
anticipate that maintaining such compliance will adversely affect the Company's
financial position. There can be no assurance, however, that such requirements
will not change so as to require significant additional expenditures or
operating costs.
 
COMPETITION
 
  WMNA encounters intense competition, primarily in the pricing and rendering
of services, from various sources in all phases of its waste management and
related operations. In the solid waste collection phase, competition is
encountered, for the most part, from national, regional and local collection
companies as well as from municipalities and counties (which, through use of
tax revenues, may be able to provide such services at lower direct charges to
the customer than can WMNA) and some large commercial and industrial companies
which handle their own waste collection. In the solid waste transfer, resource
recovery and disposal phases of its operations, competition is encountered
primarily from municipalities, counties, local governmental agencies, other
national or regional waste management companies and certain large corporations
not primarily involved in
 
                                       19
<PAGE>
 
the solid waste management services business. The Company also encounters
intense competition in pricing and rendering of services in its portable
sanitation service business, and the on-site industrial cleaning services
business of Rust managed by WMNA, from numerous large and small competitors. In
addition, Rust's program and facilities management business encounters intense
competition, primarily in pricing, quality and reliability of services, from
various sources in all aspects of its business.
 
  In its hazardous waste management operations, the Company encounters
competition from a number of sources, including several national or regional
firms specializing primarily in chemical waste management, local waste
management concerns and, to a much greater extent, generators of chemical
wastes which seek to reduce the volume of or otherwise process and dispose of
such wastes themselves. The basis of competition is primarily technical
expertise and the price, quality and reliability of service.
 
  WM International encounters intense competition from local companies and
governmental entities in particular countries, as well as from major
international companies. Pricing, quality of service and type of equipment
utilized are the primary methods of competition for collection services, and
proximity of suitable treatment or disposal facilities, technical expertise,
price, quality and reliability of services are the primary methods of
competition for treatment and disposal services.
 
  WTI experiences substantial competition in all aspects of its business. It
competes with a large number of firms, both nationally and internationally,
some of which may have substantially greater financial and technical resources
than WTI. The principal competitive factors with respect to its project
development activities include technological performance, service, technical
know-how, price and performance guarantees. Competing for selection as a
project developer may require commitment of substantial resources over a long
period of time, without any certainty of being ultimately selected. Competition
for attractive development opportunities is intense, as there are a number of
competitors in the industry interested in such opportunities.
 
  Pursuant to the First Amended and Restated International Business
Opportunities Agreement, dated January 1, 1993, by and among CWM, WTI, Waste
Management International, Inc., WM International, Rust and the Company (as
amended, the "IBOA"), each of CWM, WTI, Rust and the Company has agreed that,
until the later of July 1, 2000 or the date on which the Company ceases to
beneficially own a majority of the outstanding voting equity interests of such
subsidiary or ceases to beneficially own a majority of the outstanding voting
equity interests of WM International, and in each case no longer has an option
to obtain such ownership, such subsidiary or the Company will not engage
(except through WM International) in waste management services; design,
development, construction and operation of trash-to-energy facilities in Italy
or Germany; collection, storage, processing, treatment or disposal of hazardous
wastes (including hazardous substance remediation services); or design,
engineering and construction (where the customer is seeking third-party
operation), operation and maintenance of water, wastewater and sewage treatment
facilities (including facilities for treating hazardous waste streams whether
or not the customer is seeking third-party operation) outside North America
(i.e., the United States, its territories and possessions, Canada and Mexico)
(the "WM International Allocated Activities"), except with respect to licensing
of technology and minor interests of CWM, WTI or Rust in publicly held
entities. WTI may engage outside North America in the design, engineering,
construction, operation and maintenance of chimneys and air pollution control
facilities (the "WTI Allocated Activities"). Rust may engage outside North
America in activities relating to industrial facility and power plant
maintenance services (the "Rust Allocated Activities"). Sales by the Company of
recyclables, licensing of technology and minor investments by the Company in
publicly held entities are also permitted activities of the Company outside
North America. WM International has agreed that for the same time periods as
are applicable to CWM, WTI, Rust and the Company above in this paragraph, it
will not engage in North America in the type of activities included within the
WM International Allocated Activities outside North America and will not engage
in the WTI Allocated Activities or the Rust Allocated Activities. Businesses or
assets acquired by a party to the IBOA which are in the domain of another party
thereto (according to the allocations described above) must be offered for sale
to the other party at fair market value.
 
  In addition, WTI and WM International have entered into an agreement whereby
WTI will have primary responsibility for the early-stage development of trash-
to-energy projects outside North America (except in Italy
 
                                       20
<PAGE>
 
and Germany) and WM International will have the right to acquire up to 49% of
all equity of any such project available to WM International, WTI and their
affiliates, with WTI or other investors owning the balance. This arrangement
is non-cancelable by WTI or WM International without the other's consent prior
to 2000. If the arrangement is canceled, the right to develop trash-to-energy
projects reverts to being part of the WM International Allocated Activities.
 
  By agreement among the parties, the Company is responsible for determining
business allocations among CWM, WTI, Rust, the Company and WM International
which are not controlled by the allocations set forth in the preceding two
paragraphs. In this connection CWM, WTI, Rust, the Company and WM
International have agreed that in order to minimize the potential for
conflicts of interest among various subsidiaries under the common control of
the Company and for so long as the Company shall have beneficial ownership of
a majority of the outstanding voting equity interests of such subsidiary (or
an option to obtain such ownership), the Company has the right to direct
future business opportunities to the Company or the Company-controlled
subsidiary which, in the Company's reasonable and good faith judgment, has the
most experience and expertise in that line of business, provided that the
Company may not allocate a business opportunity to a particular subsidiary if
such business opportunity would involve the subsidiary in a breach of its
agreement not to compete as described in the immediately preceding paragraphs.
Opportunities outside North America relating to the provision of future waste
management services are generally to be allocated to WM International, except
that opportunities outside North America relating to the WTI Allocated
Activities and the Rust Allocated Activities are generally to be allocated to
WTI and Rust, as the case may be. No party is liable for consequential
damages, except for lost profits, for any breach of the IBOA.
 
  In addition, in connection with the transfer by Rust of its hazardous and
radioactive substance remediation business in 1995 and its scaffolding rental
and erection business in 1996, the Company and Rust agreed with the respective
purchasers not to engage in providing those services in North America prior to
2002 (in the case of the remediation business) and 2001 (in the case of the
scaffolding business). In connection with WTI's sale of its water process,
manufacturing and custom engineering business, the Company and WTI agreed with
the purchaser not to engage in such business in the United States or any other
country in which WTI conducted such business at the time of sale until 2001.
 
INSURANCE
 
  While the Company believes it operates professionally and prudently, its
business exposes it to various risks, including, for example, the potential
for harmful substances escaping into the environment and causing damage or
injuries, the cost of which could be substantial. The Company currently
maintains liability insurance coverage for occurrences under various
environmental impairment, primary casualty and excess liability insurance
policies.
 
  The Company's insurance program includes coverage for pollution liability
resulting from "sudden and accidental" releases of contaminants and
pollutants. The Company believes that the coverage terms, available limits of
liability, and costs currently offered by the insurance market do not
represent sufficient value to warrant the purchase of "non-sudden and
accidental" pollution liability insurance coverage. As such, the Company has
chosen not to purchase risk transfer "non-sudden and accidental" pollution
liability insurance coverage. To satisfy existing government requirements, the
Company has secured non-risk transfer pollution liability insurance coverage
in amounts believed to be in compliance with federal and state law
requirements for "non-sudden and accidental" pollution. The Company must
reimburse the insurer for losses incurred and covered by this insurance
policy. In the event the Company continues not to purchase risk transfer "non-
sudden and accidental" pollution liability insurance coverage, the Company's
net income could be adversely affected in the future if "non-sudden and
accidental" pollution losses should occur.
 
EMPLOYEES
 
  The Company and its subsidiaries employ a total of approximately 58,900
persons in their worldwide continuing operations. Of this number, the Company
employs approximately 37,200 persons in its North
 
                                      21
<PAGE>
 
American solid and hazardous waste management services operations (excluding
employees of the Rust on-site industrial cleaning services business operated
by WMNA). Of this total, approximately 27,600 persons are employed in solid
and hazardous waste collection, transfer, resource recovery and disposal
activities, and approximately 9,600 in managerial, executive, sales, clerical,
data processing and other solid waste and related activities.
 
  As of December 31, 1997, WM International employed approximately 14,600
persons. Of this number, approximately 10,400 persons were employed in its
collection services operations, 2,300 in its treatment and disposal services
operations and 1,900 in administrative functions.
 
  As of December 31, 1997, WTI had approximately 1,900 full-time employees in
its continuing operations.
 
  Rust employed approximately 5,200 persons at December 31, 1997 in the on-
site industrial cleaning services business managed by WMNA and Rust's program
and facilities management services business.
 
ACQUISITIONS AND DISPOSITIONS
 
  Since August 1971, the Company has acquired a number of companies, and
certain assets of other companies, engaged in various phases of the
environmental services industry. See Note 5 to the Company's Consolidated
Financial Statements set forth below in Item 8. The amounts and types of
consideration generally have been determined by direct negotiations with the
owners of the businesses acquired. In most instances, the owners of the
acquired businesses were few in number, and often certain key former owners
have continued to operate the businesses following acquisition by the Company.
During 1997, the Company continued to acquire additional operations in the
waste management services industry, purchasing 45 businesses for an aggregate
of $51.4 million in cash and notes, assumed debt of $17.6 million, and
approximately 122,000 shares of the Company's common stock.
 
  Acquisitions have historically contributed significantly to the Company's
growth. However, in recent years the Company's acquisition activity relative
to the size of its revenue base has significantly decreased, and the Company
has disposed of significant amounts of non-waste management services
businesses and assets, as well as underperforming or poorly positioned waste
management services businesses. As it focuses on its core waste management
services business, the Company intends to continue engaging in such
dispositions. The Company's growth prospects may be affected by the decision
to engage in such dispositions and by the availability of additional business
acquisitions at reasonable prices and the Company's ability to finance such
acquisitions. See "Management's Discussion and Analysis of Results of
Operations and Financial Condition" set forth below in Item 7 for a discussion
of capital expenditures by the Company, including acquisitions. Other well-
capitalized companies also compete intensely for businesses available to be
acquired.
 
  The acquisition of businesses entails certain inherent risks. Although the
Company reviews businesses to be acquired, because of the nature of the
liabilities involved in these businesses, there can be liabilities which will
not become known until after the transactions are consummated. The Company
seeks to minimize the impact of these liabilities and expenditures by
attempting to obtain indemnities and warranties from the seller which may be
supported by deferring payment of a portion of the purchase price. These
indemnities and warranties, if obtained, may not, however, fully cover the
liabilities due to their limited scope, amount, or duration, the financial
limitations of the indemnitor or warrantor, or other reasons. Businesses
purchased may require expenditures to make up for deferred maintenance and to
improve the quality or quantity of assets acquired. In certain cases, the
Company establishes reserves in respect of the anticipated costs of
remediation for acquired sites.
 
  In June 1996, the Company announced plans to divest $1.0 billion of non-core
assets and non-integrated businesses by the end of 1998. In February 1997, the
Company announced plans to divest an additional $1.5 billion of such
investments by the end of 1999. As a result of these divestiture programs, the
Company and its subsidiaries have sold the following businesses and
investments: Rust sold its North American engineering and
 
                                      22
<PAGE>
 
construction business and its industrial scaffolding businesses in 1996; WTI
sold its water process, manufacturing and custom-engineered systems businesses
in 1996; WM International entered into an agreement in 1996 to sell its
investment in Wessex Water Plc (which transaction closed in 1997); the Company
sold its approximately 20% interest in ServiceMaster L.P. ("ServiceMaster") to
ServiceMaster for approximately $626 million in 1997; WTI sold its remaining
water services business to U.S. Filter for 2.3 million registered shares of
U.S. Filter, valued at approximately $64 million, in 1997; WM International
sold substantially all of its operations in France and Spain in 1997 and
entered into an agreement to sell its Hamm, Germany waste-to-energy facility
in 1997 (which transaction closed in 1998); and the Company sold certain of
its North American solid waste operations. The Company's plans also include
the sale by Rust of its remaining domestic and international engineering and
consulting business and the sale or joint venturing of the WM International
business in Austria.
 
  In connection with the Merger Agreement with USA Waste, the Company may be
required to dispose of certain of its waste management businesses and assets.
See also "Management's Discussion and Analysis of Results of Operations and
Financial Condition--Financial Condition" set forth below in Item 7.
 
  For a more detailed discussion of the Company's recent acquisitions and
dispositions, see "Management's Discussion and Analysis of Results of
Operations and Financial Condition--Results of Operations" set forth below in
Item 7, and Note 5 to the Company's Consolidated Financial Statements which
are set forth below in Item 8.
 
ITEM 2. PROPERTIES.
 
  The principal property and equipment of the Company consists of land
(primarily disposal sites), buildings and waste treatment or processing
facilities (other than disposal sites), and vehicles and equipment, which as
of December 31, 1997 represented approximately 14%, 7% and 33%, respectively,
of the Company's total consolidated assets. The Company believes that its
vehicles, equipment and operating properties are well maintained and suitable
for its current operations. See "Management's Discussion and Analysis of
Results of Operations and Financial Condition" set forth below in Item 7 for a
discussion of property and equipment expenditures by the Company for the last
four years and the capital budget for 1998. The Company's subsidiaries lease
numerous office and operating facilities throughout the world. For the year
ended December 31, 1997, aggregate annual rental payments on real estate
leased by the Company and its subsidiaries approximated $111.4 million.
 
  The principal fixed assets of WMNA consist of vehicles and equipment (which
include, among other items, approximately 19,900 collection and transfer
vehicles, 1.5 million containers and 24,600 stationary compactors in the
United States and Canada). WMNA owns or leases real property in most states in
which it is doing business. At December 31, 1997, 101 solid waste disposal
facilities, aggregating approximately 65,440 total acres, including
approximately 16,170 permitted acres, were owned by WMNA in the United States
and Canada and 29 facilities, aggregating approximately 13,560 total acres,
including approximately 6,035 permitted acres, were leased from parties not
affiliated with WMNA under leases expiring from 1998 to 2085. At December 31,
1997, the Company owned or leased in the United States a total of seven
treatment, storage or disposal facilities. At such date, the Company's seven
United States chemical waste facilities with secure land disposal sites
aggregated approximately 7,870 acres, including approximately 1,475 permitted
acres.
 
  The principal property and equipment of WM International consist of land
(primarily disposal sites) and vehicles and equipment, which as of December
31, 1997 represented approximately 9.3% and 20.4%, respectively, of WM
International's assets. The principal fixed assets utilized in WM
International's collection services operations at December 31, 1997, consisted
of vehicles and equipment (which included, among other items, approximately
6,700 collection, transportation, and other route vehicles and approximately
260 pieces of landfill and other heavy equipment), and approximately 310,000
containers, including approximately 3,300 stationary compactors. In addition,
WM International owns approximately 730 pieces of hazardous waste equipment,
consisting predominately of containers and collection vehicles.
 
  WTI currently owns, operates or leases 16 trash-to-energy facilities (which
facilities are capable of processing up to 23,750 tons of solid waste per
day), eight cogeneration and small power production facilities,
 
                                      23
<PAGE>
 
two coal handling facilities, biosolids drying, pelletizing and composting
facilities, and various other office and warehouse facilities. Facilities
leased or operated (but not owned) by WTI are under leases or agreements
having terms expiring from the years 1998 to 2020, subject to renewal options
in certain cases.
 
ITEM 3. LEGAL PROCEEDINGS.
 
  The continuing business in which the Company is engaged is intrinsically
connected with the protection of the environment and the potential for the
unintended or unpermitted discharge of materials into the environment. In the
ordinary course of conducting its business activities, the Company becomes
involved in judicial and administrative proceedings involving governmental
authorities at the federal, state and local level, including, in certain
instances, proceedings instituted by citizens or local governmental
authorities seeking to overturn governmental action where governmental
officials or agencies are named as defendants together with the Company or one
or more of its subsidiaries, or both. In the majority of the situations where
proceedings are commenced by governmental authorities, the matters involved
relate to alleged technical violations of licenses or permits pursuant to
which the Company operates or is seeking to operate or laws or regulations to
which its operations are subject or are the result of different
interpretations of the applicable requirements. From time to time, the Company
pays fines or penalties in environmental proceedings relating primarily to
waste treatment, storage or disposal facilities. Subject to the discussion set
forth below concerning the New Milford, Connecticut landfill, which is owned
and operated by a wholly owned subsidiary of the Company, the Company believes
that these matters will not have a material adverse effect on its results of
operations or financial condition. However, the outcome of any particular
proceeding cannot be predicted with certainty, and the possibility remains
that technological, regulatory or enforcement developments, the results of
environmental studies or other factors could materially alter this expectation
at any time.
 
  The Company or certain of its subsidiaries have been identified as
potentially responsible parties in a number of governmental investigations and
actions relating to waste disposal facilities which may be subject to remedial
action under Superfund. The majority of these proceedings are based on
allegations that certain subsidiaries of the Company (or their predecessors)
transported hazardous substances to the sites in question, often prior to
acquisition of such subsidiaries by the Company. Such proceedings arising
under Superfund typically involve numerous waste generators and other waste
transportation and disposal companies and seek to allocate or recover costs
associated with site investigation and cleanup, which costs could be
substantial.
 
  As of December 31, 1997, the Company or its subsidiaries had been notified
that they are potentially responsible parties in connection with 89 locations
listed on the Superfund National Priority List ("NPL"). Of the 89 NPL sites at
which claims have been made against the Company, 17 are sites which the
Company has come to own over time. All of the NPL sites owned by the Company
were initially sited by others as land disposal facilities. At each of the 17
owned facilities, the Company is working in conjunction with the government to
characterize or to remediate identified site problems. In addition, at these
17 facilities the Company has either agreed with other legally liable parties
on an arrangement for sharing the costs of remediation or is pursuing
resolution of an allocation formula. The 72 NPL sites at which claims have
been made against the Company and which are not owned by the Company are at
different procedural stages under Superfund. At some of these sites, the
Company's liability is well defined as a consequence of a governmental
decision as to the appropriate remedy and an agreement among liable parties as
to the share each will pay for implementing that remedy. At others, where no
remedy has been selected or the liable parties have been unable to agree on an
appropriate allocation, the Company's future costs are uncertain.
 
  The Company periodically reviews its role, if any, with respect to each such
site, giving consideration to the nature of the Company's alleged connection
to the location (e.g., owner, operator, transporter or generator), the extent
of the Company's alleged connection to the location (e.g., amount and nature
of waste hauled to the location, number of years of site operation by the
Company or other relevant factors), the accuracy and strength of evidence
connecting the Company to the location, the number, connection and financial
ability of other named and unnamed potentially responsible parties at the
location, and the nature and estimated cost of the likely
 
                                      24
<PAGE>
 
remedy. Where the Company concludes that it is probable that a liability has
been incurred, a provision is made in the Company's financial statements for
the Company's best estimate of the liability based on management's judgment and
experience, information available from regulatory agencies and the number,
financial resources and relative degree of responsibility of other potentially
responsible parties who are jointly and severally liable for remediation of a
specific site, as well as the typical allocation of costs among such parties.
If a range of possible outcomes is estimated and no amount within the range
appears to be a better estimate than any other, then the Company provides for
the minimum amount within the range, in accordance with generally accepted
accounting principles. Amounts recorded are discounted where appropriate. Sites
subject to state action under state laws similar to the federal Superfund
statute are treated by the Company in the same way as NPL sites.
 
  The Company's estimates are subsequently revised, as deemed necessary, as
additional information becomes available. While the Company does not anticipate
that the amount of any such revisions will have a material adverse effect on
the Company's operations or financial condition, the measurement of
environmental liabilities is inherently difficult and the possibility remains
that technological, regulatory or enforcement developments, the results of
environmental studies, or other factors could materially alter this expectation
at any time. Such matters could have a material adverse impact on earnings for
one or more fiscal quarters or years.
 
  From time to time, the Company and certain of its subsidiaries are named as
defendants in personal injury and property damage lawsuits, including purported
class actions, on the basis of a Company subsidiary's having owned, operated or
transported waste to a disposal facility which is alleged to have contaminated
the environment or, in certain cases, conducted environmental remediation
activities at sites. Some of such lawsuits may seek to have the Company or its
subsidiaries pay the costs of groundwater monitoring and health care
examinations of allegedly affected persons for a substantial period of time
even where no actual damage is proven. While the Company believes it has
meritorious defenses to these lawsuits, their ultimate resolution is often
substantially uncertain due to the difficulty of determining the cause, extent
and impact of alleged contamination (which may have occurred over a long period
of time), the potential for successive groups of complainants to emerge, the
diversity of the individual plaintiffs' circumstances, and the potential
contribution or indemnification obligations of co-defendants or other third
parties, among other factors. Accordingly, it is possible such matters could
have a material adverse impact on the Company's earnings for one or more fiscal
quarters or years.
 
  A Company subsidiary has been involved in litigation challenging a municipal
zoning ordinance which restricted the height of its New Milford, Connecticut,
landfill to a level below that allowed by the permit previously issued by the
Connecticut Department of Environmental Protection ("DEP"). Although a lower
Court had declared the zoning ordinance's height limitation unconstitutional,
during 1995 the Connecticut Supreme Court reversed this ruling and remanded the
case for further proceedings in the Superior Court. In November 1995, the
Superior Court ordered the subsidiary to apply for all governmental permits
needed to remove all waste above the height allowed by the zoning ordinance,
and the Connecticut Supreme Court has upheld that ruling. The Company is
complying with the order of the Superior Court while also seeking an
alternative resolution to this matter. The Company is unable to predict the
outcome of this matter at this time. Depending upon the nature of any plan
eventually approved by applicable regulatory authorities for removing the
waste, the actual volume of waste to be moved, and other currently unforseeable
factors, the subsidiary could incur costs which would have a material adverse
impact on the Company's results of operations in one or more future periods.
 
  The Company has brought suit against a substantial number of insurance
carriers in an action entitled Waste Management, Inc. et al. v. The Admiral
Insurance Company, et al. pending in the Superior Court in Hudson County, New
Jersey. In this action the Company is seeking a declaratory judgment that
environmental liabilities asserted against the Company or its subsidiaries, or
that may be asserted in the future, are covered by insurance policies purchased
by the Company or its subsidiaries. The Company is also seeking to recover
defense costs and other damages incurred as a result of the assertion of
environmental liabilities against the Company or its subsidiaries for events
occurring over at least the last 25 years at approximately 140 sites and the
defendant insurance carriers' denial of coverage of such liabilities. While the
Company has reached settlements with some
 
                                       25
<PAGE>
 
of the carriers, the remaining defendants have denied liability to the Company
and have asserted various defenses, including that environmental liabilities
of the type for which the Company is seeking relief are not risks covered by
the insurance policies in question. The remaining defendants are contesting
these claims vigorously. Discovery is nearly complete as to the 12 sites in
the first phase of the case and discovery is expected to continue for several
years as to the remaining sites. Currently, trial dates have not been set. The
Company is unable at this time to predict the outcome of this proceeding. No
amounts have been recognized in the Company's financial statements for
potential recoveries.
 
  Several purported class action lawsuits and one purported derivative lawsuit
seeking injunctive relief and unspecified money damages were filed in the
Chancery Court in and for New Castle County, Delaware against the Company,
WTI, and individual directors of WTI in connection with the June 20, 1997
proposal by the Company to acquire all of the shares of WTI common stock which
the Company does not own. The Company has agreed to a merger in which WTI's
stockholders would receive $16.50 in cash per share of WTI's common stock. See
"Business--General" above. The lawsuits allege, among other things, that the
defendants have breached fiduciary duties to WTI's minority stockholders
because the merger consideration contemplated by the proposal was inadequate
and unfair. In addition, the purported derivative lawsuit alleges that the
proposal was part of a plan to misappropriate WTI's corporate opportunity to
repurchase its own shares. The Company believes that its actions and those of
WTI and its Board of Directors in connection with the proposal have been in
accordance with Delaware law. Accordingly, the Company intends to contest
these lawsuits vigorously.
 
  In November and December 1997, several alleged purchasers of the Company's
stock brought purported class action lawsuits against the Company and several
of its current and former officers in the United States District Court for the
Northern District of Illinois. Each of the lawsuits asserts that the
defendants violated the federal securities laws by issuing allegedly false and
misleading statements in 1996 and 1997 about the Company's financial
condition. Among other things, the plaintiffs allege that the Company employed
accounting practices that were improper and that caused its publicly filed
financial statements to be materially false and misleading. The lawsuits
demand, among other relief, unspecified monetary damages, attorneys' fees and
the costs of conducting the litigation. The Company intends to defend itself
vigorously in this litigation. In January 1998, the 14 purported class actions
were consolidated before one judge in the Northern District of Illinois.
Plaintiffs have until May 1998 to file a consolidated amended complaint. It is
not possible at this time to predict the impact this litigation may have on
the Company, although it is reasonably possible that the outcome may have a
materially adverse impact on its financial condition or results of operations
in one or more future periods.
 
  The Company is also aware that the Securities and Exchange Commission has
commenced a formal investigation with respect to the Company's previously
filed financial statements and related accounting policies, procedures and
system of internal controls. The Company intends to cooperate with such
investigation. The Company is unable to predict the outcome or impact of this
investigation at this time.
 
  A lawsuit by an alleged Company stockholder purporting to represent a class
of the Company's stockholders has been filed in the Chancery Court in and for
New Castle County, Delaware (although the Company has not yet been served)
against the Company and members of its Board of Directors alleging breaches of
fiduciary duty by the defendants in connection with the Merger with USA Waste.
The lawsuit seeks, among other things, to have the Merger enjoined and to
recover unspecified damages. The Company believes the suit to be without merit
and intends to contest it vigorously.
 
  The Company and certain of its subsidiaries are also currently involved in
other civil litigation and governmental proceedings relating to the conduct of
their business. While the outcome of any particular lawsuit or governmental
investigation cannot be predicted with certainty, the Company believes that
these matters will not have a material adverse effect on its financial
condition or results of operations.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.
 
  No matters were submitted to the Company's security holders during the

  At March 1, 1998, the Company had approximately 45,000 stockholders of
record.
 
  Due in part to the high level of public awareness of the business in which
the Company is engaged, regulatory enforcement proceedings or other
unfavorable developments involving the Company's operations or facilities,
including those in the ordinary course of business, may be expected to
engender substantial publicity which could from time to time have an adverse
impact upon the market price for the Company's common stock.
 
  In February 1997, the Company's Board of Directors approved a new repurchase
program to replace the program approved in December 1995. Under the new
program, the Company is authorized to purchase during 1997 and 1998 up to 50
million shares of its common stock in the open market, in privately negotiated
transactions or through issuer tender offers. The Company repurchased 30
million shares through a "Dutch auction" tender offer in the second quarter of
1997 but did not repurchase any other shares that year. The Company does not
expect to conduct any repurchases in 1998.
 
  During 1994, 1995, 1996 and 1997, the Company sold put options on 42.3
million shares of its common stock in conjunction with the repurchase program.
The put options gave the holders the right at maturity to require the Company
to repurchase its shares at specified prices. In the event the options were
exercised, the Company could elect to pay the holder in cash the difference
between the strike price and the market price of the Company's shares, in lieu
of repurchasing the stock. For information concerning the exercise or
expiration of these put options and related information, see "Management's
Discussion and Analysis of Results of Operations and Financial Condition--
Financial Condition" set forth below in Item 7.
 
  The Company's ability to pay dividends is restricted under a credit
agreement; however, so long as no event of default has occurred and is
continuing, the Company is permitted to pay regularly scheduled dividends in
amounts not to exceed $100 million in any calendar quarter. However, the
Merger Agreement with USA Waste limits the Company to current dividends of
$0.17 per share, or approximately $77.35 million per quarter.

Notes:
 (1) As a result of a comprehensive review begun in the third quarter of 1997,
     the Company determined that certain items of expense were incorrectly
     reported in previously issued financial statements. The Company has
     accordingly restated its financial results for the years 1992 through
     1996. Stockholders' equity, at December 31, 1991, was restated from
     $4,133.1 million to $3,934.5 million. (See Note 2 to Consolidated
     Financial Statements).
 (2) The Company recorded an asset impairment loss in 1997, and restated prior
     year financial statements to retroactively recognize impairment losses in
     earlier years. See Note 16 to Consolidated Financial Statements.
 (3) The results for 1992 include a non-taxable gain of $351.1 million (before
     minority interest) resulting from the initial public offering of Waste
     Management International plc ("WM International"), less $80.6 million of
     related exit costs, primarily to write down international assets not
     included in WM International, as well as special charges of $219.9
     million (before tax and minority interest) primarily related to
     writedowns of the Company's medical waste business, Chemical Waste
     Management Inc. ("CWM") incinerators in Chicago, Illinois, and Tijuana,
     Mexico, a former subsidiary's investment in its asbestos abatement
     business, and certain costs incurred by the former subsidiary and CWM
     related to the formation of Rust International Inc. ("Rust").
 (4) The results for 1993 include a non-taxable gain of $15.1 million (before
     minority interest), relating to the issuance of shares by Rust, as well
     as a special asset revaluation and restructuring charge of $524.8 million
     (before tax and minority interest) recorded by CWM related primarily to a
     revaluation of its thermal treatment business, and a provision of
     approximately $14 million to adjust deferred income taxes resulting from
     the 1993 tax law change.
 (5) The results for 1995 include a special charge of $140.6 million (before
     tax) recorded by CWM, primarily to write off its investment in facilities
     and technologies that it abandoned because they do not meet customer
     service or performance objectives, and a special charge of $194.6 million
     (before tax and minority interest) recorded by WM International relating
     to actions it had decided to take to sell or otherwise dispose of non-
     core businesses and investments, as well as core businesses and
     investments in low potential markets, abandon certain hazardous waste
     treatment and processing technologies, and streamline its country
     management organization.
 (6) In 1995, the Rust Board of Directors approved a plan to sell or otherwise
     discontinue Rust's process engineering, construction, specialty
     contracting and similar lines of business. During 1996, the sale of the
     industrial process engineering and construction business, based in
     Birmingham, Alabama, was completed. In 1996, Wheelabrator Technologies
     Inc. ("WTI") sold its water process systems and equipment manufacturing
     businesses, and Rust sold its industrial scaffolding business. WTI
     entered into an agreement to sell its water and wastewater facility
     operations and privatization business and Rust began implementing plans
     to exit its remaining domestic and international engineering and
     consulting business. These businesses were classified as discontinued
     operations in the financial statements. The Rust disposition was not
     completed within one year, and accordingly in 1997 this business has been
     reclassified back into continuing operations, as operations held for
     sale, in accordance with generally accepted accounting principles. The
     unused portion ($87.0 million) of the previously recorded provision for
     loss on disposal was reversed in discontinued operations, and an
     impairment loss provision of $122.2 million was recognized in continuing
     operations.
 (7) The results for 1996 include special charges of $47.1 million (before tax
     and minority interest) related to WM International's sale of its
     investment in Wessex Water Plc and a charge of $169.5 million (before tax
     and minority interest) to revalue its investments in France, Austria and
     Spain in contemplation of exiting these markets and to write off an
     investment in a hazardous waste disposal facility. Also in 1996, Waste
     Management of North America, Inc. ("WMNA") and CWM recorded special
     charges of $154.1 million (before tax) for reengineering their finance
     and administration functions and increasing reserves for certain
     litigation.
 (8) In 1997, the Company recorded a special charge of $41.6 million (pretax)
     for severance related to WMNA, and WM International recorded a charge of
     $104.4 million (before tax and minority interest) to reflect costs of
     demobilization following the loss of the contract renewal for Buenos
     Aires, Argentina, divestiture or closure of underperforming businesses,
     and the writeoff of projects it decided to no longer pursue.
 (9) In 1992, the Company changed its accounting for income taxes and post-
     retirement benefits other than pensions as a result of new standards
     issued by the Financial Accounting Standards Board. In 1995, the Company
     changed its accounting for capitalized interest on landfill cell
     construction. See Note 3 to Consolidated Financial Statements.
(10) Earnings were inadequate to cover fixed charges in 1997. Earnings would
     have to increase by $1,026.1 million to cover fixed charges and bring the
     ratio of earnings to fixed charges to one-to-one.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
        FINANCIAL CONDITION.
 
                 (TABLES IN MILLIONS EXCEPT PER SHARE AMOUNTS)
 
  As more fully described in the Notes to Consolidated Financial Statements,
certain financial information in this Report has been restated to correct
previously issued financial statements.
 
  On March 10, 1998, the Company entered into a definitive merger agreement
(the "Merger Agreement") with USA Waste Services, Inc. ("USA Waste") pursuant
to which the Company will be merged with a wholly-owned subsidiary of USA
Waste (the "Merger"). Pursuant to the Merger Agreement, the Company's
stockholders will receive .725 shares of common stock of USA Waste for each
share of common stock of the Company. The consummation of the Merger is
subject to a number of conditions, including the expiration or termination of
the applicable merger review waiting period under the Hart-Scott-Rodino Anti-
Trust Improvements Act of 1976, approval by the stockholders of each company
and other typical closing conditions. In addition, the Merger is contingent
upon the transaction qualifying for pooling-of-interests accounting treatment.
In order to qualify for pooling-of-interests accounting treatment, the Company
intends to sell a portion of its treasury shares pursuant to a registered
public offering prior to the closing of the Merger. A lawsuit by an alleged
Company stockholder purporting to represent a class of the Company's
stockholders has been filed (although the Company has not yet been served)
against the Company and the members of its Board of Directors alleging
breaches of fiduciary duty by the defendants in connection with the Merger.
The lawsuit seeks, among other things, to have the transaction enjoined and to
recover unspecified damages. The Company believes the suit to be without merit
and intends to contest it vigorously.
 
  Upon the consummation of the Merger, certain long-term debt of Waste
Management International plc ("WM International") may be accelerated and
become payable with three months notice. At December 31, 1997, this debt
totalled approximately $209 million, but by March 17, 1998 had been reduced to
$71 million. In addition, Wessex Water Plc ("Wessex") has an option to acquire
WM International's ownership in its United Kingdom business at fair market
value that may become exercisable upon the consummation of the Merger. In
1997, this business had revenues of approximately $276 million and operating
income (before minority interest) of approximately $25 million. WM
International had a net investment of approximately $315 million in the
business at December 31, 1997.
 
RESULTS OF OPERATIONS
 
CONSOLIDATED
 
  Consolidated 1997 (loss) from continuing operations of Waste Management,
Inc. (formerly WMX Technologies, Inc.) and its subsidiaries ("Waste
Management" or the "Company") was $(1,269.3) million or $(2.72) per share
compared with income of $224.0 million or $0.46 per share in 1996, $419.9
million or $0.86 per share in 1995, and $601.5 million or $1.24 per share in
1994. Net (loss) was $(1,176.1) million or $(2.52) per share in 1997, $(39.3)
million or $(0.08) per share in 1996, with net income of $340.1 million or
$0.70 per share in 1995 and $627.5 million or $1.30 per share in 1994. Per
share amounts referred to in this paragraph and throughout Management's
Discussion and Analysis are Basic Earnings Per Share as defined by Statement
of Financial Accounting Standards ("FAS") No. 128. (See Note 11 to
Consolidated Financial Statements).
 
  Consolidated 1997 revenue from continuing operations was $9.19 billion
compared with $9.23 billion in 1996, $9.10 billion in 1995 and $8.54 billion
in 1994.
 
  Results for all periods were impacted by special charges, asset impairments,
other adjustments, changes in estimates, and for 1995 and 1997, by changes in
accounting principles.
 
  The Company has undertaken a number of initiatives in response to changing
conditions in its markets and in the environmental services industry. In
January 1997, the Board of Directors approved a package of strategic
 
                                      30
<PAGE>
 
initiatives designed to enhance stockholder value, the cornerstone of which is
a focus solely on waste management services in domestic and selected
international markets where the Company can be first or second in market
share. In support of this, the Company divested non-core and non-integrated
businesses and assets valued at approximately $1.4 billion in 1997 with an
additional $400 million targeted for disposition by the end of 1998. A
significant portion of the proceeds from the 1997 asset sales was utilized to
repurchase 30 million shares of the Company's common stock in a Dutch Auction
tender offer which was concluded in the second quarter of the year. In
November 1997, the Board of Directors approved a major organizational
restructuring and cost-control program to substantially reduce overhead in its
North American waste services operations. As a result of the restructuring,
approximately 1,200 operating manager and managerial support staff positions
were eliminated, or about 20% of that employee group. It also reduced the
number of profit centers from 250 to 31, and established a regional based
operating structure which is focused on specific customer segments, including
commercial, industrial, residential and governmental accounts. The program
additionally includes new computer systems and purchasing and fleet management
initiatives designed to further reduce the Company's operating costs over the
next three years.
 
  As a result of the strategy to focus on waste management services, late in
1996 and early 1997, the Company sold its domestic water operations as well as
its minority interest in Wessex. The environmental and infrastructure
engineering and consulting services lines of business have been classified as
continuing operations held for sale in the accompanying financial statements.
The Company had expected to complete the sale of these businesses in 1997, and
at this time is pursuing such sales. See "Discontinued Operations and Other
Asset Dispositions" below for further discussion.
 
  The Company has agreed to acquire all of the approximately 53 million shares
of Wheelabrator Technologies Inc. ("WTI") which it does not already own at a
price of $16.50 per share. A special meeting of stockholders of WTI is
scheduled for March 30, 1998 to vote on the proposal, and the transaction is
expected to close as soon as practicable thereafter if the transaction is
approved.

  The solid waste services portion of North American revenue was $5.53 billion
in 1995 compared with $5.10 billion in 1994, an increase of 8.4%. Solid waste

  Revenue growth due to acquisitions was 1.0%, with 7.4% growth resulting from
price and volume increases. A significant portion of this internal growth,
2.0%, was the result of higher average recyclable commodity prices in 1995 vs.
1994. Actual commodity sales were approximately $100 million higher due to
this higher average rate. Additionally, commodity volumes were higher in 1995
due to the Company's marketing efforts and the
 
                                      31
<PAGE>
 
acquisition of additional material recovery facilities, adding an additional
$135 million of revenue, and thus accounting for approximately 2.6% of the
North American solid waste revenue growth. The remaining 2.8% was a
combination of price and volume in the other lines of business.
 
  North American hazardous waste revenue continued to decline in 1995 as waste
minimization, recycling, over-capacity and shifting governmental regulation
and enforcement continued to adversely affect the industry. Total 1995
hazardous waste revenue was $611.4 million compared with $643.1 million in
1994. Pricing and volume were both negative, only partially offset by the 1995
acquisition of a 60% interest in Advanced Environmental Technical Services,
L.L.C. In addition, unusually high revenue in the second quarter of 1994 at
the Company's Barnwell, South Carolina, low-level radioactive waste disposal
facility adversely affected 1995 comparisons.
 
  North American (WTI) trash-to-energy revenue was essentially flat from 1994
to 1995 as higher revenue from operating plants was largely offset by lower
construction revenue on the Lisbon, Connecticut, facility (which commenced
operations January 1, 1996). Approximately 78% of the growth in revenue from
operating plants was accounted for by the Falls Township and Ridge Generating
Station facilities, which began operations in 1994. Contractual price
escalation on long-term trash disposal and energy sales contracts, partly
offset by curtailment of electrical purchases by certain utility customers,
accounted for the balance of the operating plant revenue growth. Spot pricing
on the whole was stable, although there were increases in certain markets
offset by declines in others.
 
  WM International revenue, in U.S. dollars, increased $154.2 million or 9.0%
in 1995 compared with 1994. Components of the revenue change are as follows:

</TABLE>
 
  The major cause of the 1995 volume decline was less construction revenues as
a result of the completion of the construction phase of the SENT Landfill in
Hong Kong, which opened during the year. A new pricing mechanism introduced by
the Hong Kong government in March 1995, which required generators to absorb a
portion of the disposal cost for waste brought to WM International's Hong Kong
incinerator, resulted in volume declines in certain waste streams, but the
impact was offset with other volumes. Pricing in Europe was negatively
impacted in 1995 by relatively low inflation, highly competitive conditions in
the solid waste market in France, softness in segments of the hazardous waste
market, and a continuation of lower prices on rebids of municipal contracts in
Italy. Acquisition activity continued to be below WM International's
historical levels and focused particularly on "tuck-in" acquisitions which can
complement or expand existing operations in a given market. WM International
also increased its acquisition and construction of material recovery
facilities to take advantage of an emphasis on recycling as an alternative to
land disposal.
 
  Operating Expenses. Operating expenses increased $487.0 million or 8.1% in
1995 over 1994. Remediation expenses, net of insurance recoveries increased
$29.5 million. The Company recorded additional loss reserves of $14.2 million
related to long-term contracts of its Chem-Nuclear subsidiary. In addition,
approximately $73.6 million of software development costs, certain landfill
development and expansion projects and other deferred costs which the Company
determined were not realizable were expensed in 1995.
 
  Excluding the above, operating expenses were relatively constant as a
percentage of revenue for 1995 as compared to 1994 overall. North American
solid waste operating expenses declined as a percentage of revenue
 
                                      32
<PAGE>
 
primarily as a result of higher recyclable commodity prices. In addition,
milder winter weather in many parts of North America, increased
internalization of recyclables processing, and continuing route productivity
enhancements positively impacted operating expenses. Hazardous waste operating
expenses increased, however, as a percentage of revenue in 1995 due to
continued downward pressure on prices, a lower revenue base and a shift in
revenue mix toward lower margin services offsetting the benefit of headcount
reductions. Operating expenses at WM International increased as a result of
higher labor costs in Italy and widespread strikes and industrial actions
against the government in France in the fourth quarter of 1995.
 
  Selling and administrative expenses. Selling and administrative expenses
increased $29.4 million or 2.8% in 1995 over 1994. While there was an increase
in absolute dollars, as a percentage of revenue, selling and administrative
expenses declined from 12.4% in 1994 to 12.0% in 1995. The decline as a
percentage of revenue crossed all operating groups as productivity
enhancements were instituted throughout the Company allowing selling and
administrative costs to be spread over a larger revenue base. The increase in
absolute dollars resulted primarily from acquisitions and pay-for-performance
compensation plans.
 
  Special Charges. In the first quarter of 1995, in response to the continuing
deterioration of the chemical waste services market, the Company's Chemical
Waste Management, Inc. ("CWM") subsidiary realigned its organization, and in
connection therewith, recorded a special charge of $140.6 million before tax
($91.4 million after tax). The charge related primarily to a write-off of the
investment in facilities and technologies that CWM abandoned because they did
not meet customer service or performance objectives, but also includes $22.0
million of future cash payments for rents under non-cancelable leases,
guaranteed bank obligations of a joint venture, and employee severance. The
majority of the cash expenditures were paid in 1995, although certain of the
non-cancellable leases extend through the year 2002.
 
  In the fourth quarter of 1995, WM International recorded a special charge of
$194.6 million ($152.4 million after tax) primarily related to the actions it
had decided to take to sell or otherwise dispose of non-core businesses and
investments, as well as core businesses and investments in low potential
markets, abandon certain hazardous waste treatment and processing
technologies, and streamline its country management organization. The charge
reduced the Company's income by approximately $153.3 million before tax
($111.0 million after tax). The charge included $34.3 million of cash payments
for employee severance and rents under non-cancelable leases. Approximately
$11.2 million of the cash costs were paid in 1995. The majority of the balance
was paid in 1996, although certain rent payments on abandoned leased
facilities continue into the future.

  Although the Company pursued price increases in 1996, the impact on North
American solid waste services revenue growth was minimal as a year-long
decline in recyclable commodity prices largely offset the benefit of increases
in the commercial and industrial markets. Volume growth added approximately
2.0% to such revenue. Acquisitions, net of dispositions, accounted for
approximately 1.5%. Recycling revenue declined 16.0% from 1995 to 1996 due to
the substantial price decline in recyclable commodities. The Company responded
by reducing its processing of lower grades of paper, adjusting the capacity of
its recycling operations and continually striving to reduce processing costs
and improve the marketing of commodities. However, despite these efforts, it
was unable to replace the profits associated with the stronger 1995 recyclable
commodities market. North American hazardous waste revenue declined 7.7% from
1995 as the industry problems continued.
 
  The North American trash-to-energy revenue comparison is adversely affected
by the loss of the Lisbon construction revenue in 1996. Excluding this factor,
1996 revenue grew $33.8 million, or 3.7%, to $952.3 million. The commercial
operations of the Lisbon facility, which began in January 1996, contributed
$18.4 million of the increase. WTI acquired two industrial cogeneration plants
(so-called "inside-the-fence" facilities) during the year as part of its
strategy to leverage its energy plant operating capabilities and project
finance expertise by owning and/or operating power plants for industrial
customers. Together these acquisitions contributed $7.3 million to 1996
revenue growth. Contractual price escalation at existing facilities,
additional processing at several trash-to-energy plants, and lower energy
purchase curtailment accounted for most of the remaining revenue growth.
Overall spot pricing remained stable during the year.
 
  Expressed in U.S. dollars, WM International revenue increased $48.7 million
or 2.6% in 1996 compared with 1995. Components of the revenue change are as
follows:

  Although WM International was able to implement price increases on its
services despite weak economies in many of its markets, the impact of such
increases was adversely affected by recyclable commodities prices falling
substantially from their highs in 1995. Difficult economic conditions in
Germany, France and Italy, as well as the closure of a landfill in France,
resulted in a volume decline, partially offset by hazardous waste volume
growth in The Netherlands and solid waste volume growth in the United Kingdom.
In addition, the Company was awarded contracts to design, build and operate
for fifteen years two transfer stations in Hong Kong. Construction revenue on
one of these projects contributed to revenue growth in 1996. International
acquisition activity was insignificant.
 
  Operating expenses. Operating expenses increased $145.8 million or 2.2% in
1996 over 1995. This increase was greater than the revenue increase due to
several reasons. Self-insurance expense increased $57.0 million in 1996 over
1995. This increase consisted of $31.0 million related to growth of prior
years claims, $18.0 million related to implementation of new claims reporting
processes for the Company's North American solid waste operations and $8.0
million related to higher 1996 claims and claims cost growth. In addition, the
Company accrued provisions for certain loss-making recycling contracts in 1996
totaling $12.4 million. During 1996 certain route optimization software along
with other software projects became obsolete, resulting in $7.4 million being
charged to operating expenses. Remediation expenses, net of insurance
settlement recoveries declined by $13.4 million in 1996 from 1995, primarily
as a result of additional settlements with insurance companies.
 
  Excluding the above, operating expenses for 1996 compared to 1995 increased.
A large part of the increase was due to reduced recyclable commodity prices in
1996 as compared to 1995. Major declines in recyclable
 
                                      34
<PAGE>
 
commodity pricing resulted in actual disposal cost being incurred in some
cases to physically dispose of certain commodities which could not be sold. In
addition, operating expenses were impacted by severe weather during the year,
particularly in comparison to a mild 1995 winter in North America, and higher
fuel costs. Operating expenses as a percentage of revenue for WM International
was impacted by lower margin Hong Kong construction revenues and volume
declines in Europe that more than offset productivity improvements from
streamlining of its operations. Operating expenses in the trash-to-energy
business declined in both real terms and as a percentage of revenue as the
result of the absence of the Lisbon construction revenue, which carried no
margin.
 
  Selling and administrative expenses. Selling and administrative expenses
increased only $3.7 million in 1996 from 1995. As a percentage of revenue such
expenses declined from 12.0% to 11.9%. In 1996 the Company had two large
receivables totaling $10.6 million charged to bad debt expense as a result of
disputes with one customer and insolvency of another. In addition, $8.0
million was expensed primarily to write-off obsolete sales/customer oriented
software program costs. These expenses were offset by productivity
improvements in administrative processes throughout the organization.
 
  Special Charges. In the fourth quarter of 1996, WM International recorded a
provision of $77.0 million after tax related to the sale of its investment in
Wessex and a charge of $169.5 million after tax to revalue its investments in
France, Austria and Spain in contemplation of exiting all or part of these
markets or forming joint ventures. The charge also included the write-off of
an investment in a hazardous waste disposal facility in Germany because
regulatory changes adversely affected its volumes. These charges, primarily of
a non-cash nature, reduced the Company's income by $213.6 million after tax.
 
  Also, in the fourth quarter of 1996, Waste Management and CWM recorded
pretax charges of $154.1 million ($100.2 million after tax) for reengineering
their finance and administrative functions and increasing reserves for certain
litigation, including a dispute involving the computation of royalties on the
Emelle, Alabama, hazardous waste landfill. In December 1996, a federal court
in Memphis, Tennessee, held CWM liable for approximately $100.3 million in
damages to the former owners of the Emelle site. CWM is appealing the
decision. Any settlement of the Emelle litigation would be a cash payment, but
the timing of such payment is uncertain. The balance of the charge is
primarily non-cash, with $13.4 million of cash-related items paid largely in
1997.

$5.72 billion in 1997, primarily due to divestiture of virtually all of the
Canadian business mid-year, as well as the sale of other various
underperforming North America locations. North American solid waste services
revenue growth by line of business is shown in the following table:

  Overall North American solid waste services revenue for the year decreased
0.2% primarily as a result of the effect of divestitures net of acquisitions
which accounted for a 1.5% decrease. Excluding such net divestitures, overall
revenue increased 1.3% as a result of a combination of higher prices and
increased volumes. The 1997 revenue growth started out slightly negative in
the first quarter as a result of lost customers in late 1996 following a price
increase earlier in 1996. Revenue growth generally strengthened throughout the
year, finishing with fourth quarter revenue in excess of three percent over
the prior year sales, after considering divestitures. Pricing was fairly weak
throughout the year, particularly during the first two quarters. Approximately
one-third of the internal growth for the year came from pricing and the other
two-thirds from volume. The hazardous waste segment revenue continued to
decline slightly, falling about 6.8% from 1996.
 
  The increase in the North American trash-to-energy revenues of $46.2 million
is largely attributed to $60.2 million of construction revenue for facilities
that are being built and operated by WTI but owned by customers. Excluding
this construction activity, 1997 revenue decreased $14.2 million or 1.5% from
1996 levels. Divestiture of certain biosolids landspreading contracts and
lower air pollution control engineering revenues were primarily responsible.
Spot waste disposal pricing remained stable on an overall basis compared to
1996, with slight strengthening in New England being offset by continued
downward pressure in the South Florida markets.
 
  Expressed in U.S. dollars, WM International revenue decreased $123.8 million
or 6.5% in 1997 compared with 1996. Components of the revenue change are as
follows:

  Increased landfill disposal taxes, which are passed through in disposal
rates, accounted for 2.5% out of the 4.4% revenue growth from price. Volume in
1997 was lower than 1996 in three key markets. In Italy, landfill volumes were
reduced as the result of permitting delays on landfill expansions and new
landfill projects. The impact of this reduced capacity is expected to continue
into 1998. Revenue declined in Latin America from abnormally high levels in
1996 from cleaning activities for Buenos Aires during the 1996 mayoral
election, and in Germany as a result of general economic and competitive
conditions. Partially offsetting these items were improved volumes in the
Netherlands. Divestitures impacting 1997 revenue include the sale of various
operations within France, Spain, Austria, and Germany. The sale of these
operations reduced 1997 revenue by approximately 3.5% or $67 million from 1996
levels. In addition, the weakness of the various currencies in which WM
International earns its revenues created a negative translation impact on
total reported revenue for the year. Foreign currency movement has had, and
can be expected to continue to have, an impact on reported revenue, expenses
and net income. See "Derivatives and Market Risks" for further detail.
 
  Operating Expenses. Operating expenses increased $534.6 million or 8.0% in
1997 over 1996. This increase occurred despite a slight revenue decline due to
several reasons. Remediation expenses, net of insurance recoveries increased
$96.8 million in 1997 from 1996. In 1997, insurance recoveries were $33.9
million higher than in 1996, and were more than offset by remediation cost
increases of $130.7 million. The increased remediation costs reflect $49.9
million of expense resulting from implemention of SOP 96-1 (see "Accounting
Principles" below), $14.8 million of expense related to a change in the
discount rate from 7% to 6% in the fourth quarter of 1997 and the balance
primarily related to changes in remediation cost estimates at several disposal
sites. Self-insurance expenses increased $95.0 million in 1997 from 1996. This
increase included $56.0 million related to changes in estimating techniques
with the balance coming from growth of prior years' claims. The Company
incurred losses in 1997 and accrued provisions in 1997 for loss-making
contracts totaling $136.2 million. These were primarily several large
contracts with respect to which the Company determined in 1997
 
                                      36
<PAGE>
 
that such losses would continue for the contracts' duration. A large portion
of this loss provision relates to multi-year recyclables processing contracts.
The Company also recorded $13.6 million of additional reserves related to
long-term contracts of its Chem-Nuclear subsidiary as a result of changes in
estimated contract results. Other major items affecting operating expense in
1997 were accruals of $20.3 million primarily related to excess lease
obligations, and other asset disposals or write-downs totaling $28.9 million
primarily related to hazardous waste projects, obsolete inventory, scrapped
equipment including recycling assets and obsolete/unused software.
 
  Effective October 1, 1997, the Board of Directors approved a management
recommendation to revise the Company's North American collection fleet
management policy. Front-end loaders will be replaced after 8 years, and rear-
end loaders and rolloff trucks after 10 years. The previous policy was to not
replace front-end loaders before they were a minimum of 10 years old and other
heavy collection vehicles before they were a minimum of 12 years old. As a
result of this decision, the Company recognized an impairment writedown of
$70.9 million in the fourth quarter of 1997 for those vehicles scheduled for
replacement in the next two years under the new policy. Depreciable lives were
adjusted commencing in the fourth quarter of 1997 to reflect the new policy.
Also effective October 1, 1997, the Company reduced depreciable lives on
containers from 15 and 20 years to 12 years, and ceased assigning salvage
value in computing depreciation on North American collection vehicles and
containers. These changes in estimates increased depreciation expense by $33.7
million in the fourth quarter of 1997.
 
  Also effective October 1, 1997, the Company changed its process for
estimating landfill lives. The Company now amortizes landfill costs over
estimated landfill capacity which includes permitted landfill airspace plus
expansions which are probable of being obtained in the next five years. The
Company's prior practice was to consider likely expansions in the amortization
calculations, whether or not the permits were expected to be obtained within
the next five years. Factors in determining probable expansions on a site-by-
site basis include secured rights to required land, status of legal,
environmental, regulatory and political issues, and the extent to which the
permit application process has proceeded. This change in estimate increased
depreciation and amortization by $12.7 million and the provision for closure
and post-closure by $3.1 million in the fourth quarter of 1997, and resulted
in estimated landfill capacity declining from 2.9 billion cubic yards to 1.8
billion cubic yards.
 
  After considering the above, operating expenses as a percentage of revenue
for 1997 compared to 1996 increased. Hazardous waste operating expenses
increased as a percentage of revenue due to continued pressure on prices,
lower volumes and a shift in revenue mix toward lower margin services. Trash-
to-energy operating costs increased as a percentage of revenue primarily due
to the impact of increased construction revenue, which has a lower associated
margin. WM International operating expenses increased largely as a result of
lower margins for the operations in Italy.
 
  Selling and Administrative Expenses. Selling and administrative expenses
increased $33.8 million or 3.1% in 1997 over 1996. As a percentage of revenue,
selling and administrative expenses increased from 11.9% in 1996 to 12.3% in
1997. Included in selling and administrative expenses in 1997 were $39.0
million in additional legal expense reflecting changes in estimates of
litigation-related liabilities. In addition, 1997 bad debt expense included
$8.7 million related to two large accounts receivable disputes settled in
1997, $6.7 million of accounts receivable in the New York City area that in
part were compromised as a result of agreements made with the New York City
licensing authorities, and $3.2 million for certain partner/venture
receivables. The Company also wrote off $4.0 million in various sales-related
assets which included prepaid advertising credits that were expected to expire
before their use. The Company reduced other administrative expenses as a
result of divestitures and is continuing to make productivity improvements in
many administrative areas.
 
  Special Charges. In 1997, the Company recorded a special charge of $41.6
million (primarily in the fourth quarter) for severance. Employees terminated
were primarily field operating management and related support personnel.
Approximately $5.9 million of the severance had been paid by December 31,
1997, with the balance to be paid in 1998 and thereafter.
 
                                      37
<PAGE>
 
  WM International also recorded a special charge in 1997 ($104.4 million
before tax and minority interest) to reflect the costs of demobilization in
Argentina following loss of the contract renewal for the City of Buenos Aires,
divestiture or closure of underperforming businesses, primarily in Italy and
Germany and the writeoff of costs of projects, primarily in Germany, which it
decided to no longer pursue. The charge included $14.8 million of severance,
primarily related to operating personnel in Buenos Aires and with closed or
divested businesses in Italy and Germany. These terminations are expected to
occur and the severance paid in 1998.
 
OTHER ITEMS
 
  Asset Impairment Loss. As a result of the comprehensive review of operating
assets and investments discussed in Notes 2, 3 and 16 to Consolidated
Financial Statements, the Company recorded an impairment loss of $1.48 billion
in 1997. Prior period financial statements were restated to recognize
impairment losses in earlier periods. Asset impairment loss was $34.0 million
in 1994, $53.8 million in 1995, and $64.7 million in 1996.
 
  The 1994 impairment losses included $22.4 million related to unsuccessful or
abandoned landfill development or expansion projects. In addition, the Company
abandoned certain vehicle-related systems development projects totalling $7.3
million. Several properties identified as surplus were written down to fair
value, resulting in $4.3 million in such charges.
 
  The 1995 impairment losses included $48.2 million for several unsuccessful
landfill development or expansion projects. This included one site with an
impairment loss of $29.9 million, which was recognized as a result of the
passage of legislation prohibiting a previously planned expansion.
 
  The 1996 impairment losses were primarily related to recycling investments.
Of the $47.8 million impairment loss related to these investments, $35.7
million represented goodwill, primarily related to two acquisitions made in
1995. These impairment losses were the result of major price declines in the
recyclable paper market caused by an industry wide-pricing collapse in the
pulp and paper market. In addition, impairment losses of $13.4 million were
recognized with respect to landfill facilities, primarily as a result of one
landfill site having its volumes curtailed and a planned expansion becoming
remote.
 
  In 1997 impairment losses were primarily due to revaluation of numerous
treatment and disposal facilities of the Company and associated goodwill.
Revaluation of investments in the North American hazardous waste services
business accounted for $776.2 million of the impairment loss. This impairment
was a result of continuing pricing and volume declines in the hazardous waste
services markets, which currently have excess capacity. Changes in
environmental regulations are also allowing certain hazardous waste streams to
be managed by others with less expensive treatment and disposal alternatives.
In addition, $344.8 million of the 1997 impairment losses related to solid
waste landfills. This included $163.9 million related to the Company's
abandonment of several landfill development or expansion projects. The balance
of this impairment loss was primarily the result of substantial pricing or
volume declines at certain landfills and a shortening of estimated life of 10
landfills (See Note 3 to Consolidated Financial Statements). As a result of
the Company's adoption of a new fleet replacement policy in 1997, certain
older collection vehicles became impaired and a loss was recorded totaling
$70.9 million (See Note 3 to Consolidated Financial Statements). Other 1997
impairment losses included $122.2 million related to the revaluation of Rust
International Inc. ("Rust") domestic engineering and consulting business,
discussed below under "Discontinued Operations and Other Major Asset
Dispositions". Impairment losses of $38.2 million were also recorded for
surplus real estate being held for sale. WTI recorded a 1997 impairment loss
of $57.2 million. This included $47.1 million related to revaluation of a wood
waste burning independent power production facility.

  Gross interest expense increased from 1994 to 1995 as a result of an earlier
management decision to increase the leverage of the Company. Debt levels
increased in 1995, primarily a result of the acquisition of the public
ownership of CWM and Rust. The large decline in capitalized interest in 1995
is due to a change in accounting methods effective January 1, 1995.
Capitalized interest declined further in 1996 and 1997 as significant capital
projects were completed and the Company reduced capital spending. See
"Financial Condition--Capital Structure" and Note 3 to Consolidated Financial
Statements. Although the Company repurchased a substantial number of its
shares in 1996 and 1997, debt levels were reduced in 1997 resulting in lower
interest expense.
 
  Minority Interest. Minority interest declined from 1994 to 1995 as a result
of the 1995 purchases by the Company of the publicly-owned shares of CWM and
Rust and lower earnings by certain subsidiaries, as well as the minority
interest share (approximately $41.3 million) in the WM International special
charge. Minority interest declined from 1995 to 1996 as a result of higher
earnings by certain subsidiaries and the minority interest share
(approximately $63.8 million) in the WM International special charges.
Minority interest in 1997 was comparable to 1996, and was impacted by $27.9
million related to the WM International 1997 special charge and $15.9 million
by the 1997 WTI asset impairment loss.

  Equity income in 1994, 1995 and 1996 included income from ServiceMaster L.P.
("ServiceMaster") and Wessex investments of $60.2 million, $77.0 million and
$59.4 million, respectively. These investments were sold in the second quarter
of 1997 with no equity income recorded for Wessex or ServiceMaster. Equity
income in the second quarter of 1997 was also reduced by $10.4 million related
to a special charge recorded by OHM Corporation ("OHM"), an environmental
remediation services business approximately 37% owned by Rust. Gains/(loss) on
sale of investments/businesses are primarily related to the following items
(1) $25.1 million gain on sale of the Company's Modulaire mobile office
services business in 1994; (2) $160 million gain the fourth quarter of 1995
recorded as a result of the exchange of an interest in ServiceMaster Consumer
Services L.P. for an interest in ServiceMaster and an option to purchase 1.25
million ServiceMaster limited partnership shares; (3) $30.1 million in 1996
and $43.4 million in 1997 of gains on sales of North American solid waste
businesses, (including $32.6 million on sale of Canadian operations); and (4)
$129 million gain in the first quarter of 1997 from the sale of the Company's
investment in ServiceMaster. Writedown of investments includes $19.5 million
related to the OHM investment and $6.2 million in other investments, all of
which were recorded in the fourth quarter of 1997.
 
  Income Taxes. The consolidated income tax rate varies between years as a
result of shifts in the source of taxable income. The inability to realize tax
benefits on a portion of the 1994, 1995, 1996 and 1997 special charges and
asset impairment loss resulted in an increased tax provision in those years,
primarily attributable to non-deductible goodwill and the writedown of
investments in subsidiaries. In addition, the Company increased deferred tax
valuation allowances and other tax reserves. See Note 4 to Consolidated
Financial Statements.
 
  Discontinued Operations and Other Major Asset Dispositions. During the
fourth quarter of 1995, the Company announced that Rust would sell or
discontinue its process engineering, construction, specialty contracting and
similar lines of business. Further, as the Company refined its business
strategy to focus on waste management services, other business units were
identified in 1996 and 1997 as units to be either sold or discontinued.
 
  In 1996, Rust sold its engineering and construction business as well as its
industrial scaffolding business for $295.1 million, and WTI sold its water
process, manufacturing and custom engineered systems business for
 
                                      39
<PAGE>
 
$369.6 million in cash. In 1997, Rust disposed of certain of its international
engineering and consulting businesses and WTI sold its remaining water
services business for 2.3 million registered shares of U.S. Filter stock,
valued at approximately $64 million. The Rust engineering and scaffolding
businesses and its international engineering and consulting businesses,
together with the WTI water businesses, have all been classified as
discontinued operations in the accompanying financial statements.
 
  Because Rust did not sell its remaining domestic engineering and consulting
businesses prior to December 31, 1997, these businesses have been reclassified
as continuing operations held for sale in the accompanying financial
statements for all periods. The original provision, established in 1996, for
loss on the sale (approximately $87 million) of these discontinued businesses
has been reversed as income in "income (loss) on disposal" in discontinued
operations, and a new provision for loss on sale (approximately $122 million)
was provided as an asset impairment loss in the Consolidated Statements of
Income, all in the fourth quarter of 1997. While the Company intends to sell
these businesses, it is unable to estimate when a buyer will be found and a
sale can be consummated.
 
  In 1997, Waste Management sold its investment in ServiceMaster for $626
million, and sold various non-integrated waste services businesses in North
America for $288.9 million. Additionally in 1997, WM International sold
businesses in France, Spain, Austria and Germany for $128.3 million and its
approximately 20% interest in Wessex for approximately $300 million.
 
  In early 1998, WM International sold its Hamm, Germany waste-to-energy
facility for $137 million. Also in early 1998, Rust's 37% ownership of OHM was
sold for cash totaling $111.2 million. This sale occurred in connection with
the merger of OHM with International Technology Corporation. As part of this
transaction, Rust received a distribution of shares of NSC Corporation, a
leading U.S. asbestos abatement contractor, increasing its ownership of NSC
Corporation to 54.3%.
 
ACCOUNTING PRINCIPLES
 
  Effective January 1, 1994, the Company adopted FAS No. 112, "Employers'
Accounting for Postemployment Benefits." The change reduced 1994 net income by
$1.3 million.
 
  Effective January 1, 1995, the Company changed its method of capitalizing
interest on landfill cell construction. See Note 3 to Consolidated Financial
Statements. The change reduced 1995 net income by $84.7 million.
 
  Effective January 1, 1996, the Company adopted FAS No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of." The effect of adoption was not material. Impairments recorded prior to
1996 followed a methodology consistent with FAS No. 121.
 
  FAS No. 123, "Accounting for Stock-Based Compensation" also became effective
in 1996. However, FAS No. 123 permitted compensation to continue to be
accounted for under Accounting Principles Board Opinion No. 25, and the
Company elected to follow this alternative. See Note 9 to Consolidated
Financial Statements.
 
  Effective January 1, 1997, the Company adopted American Institute of
Certified Public Accountants Statement of Position ("SOP") 96-1,
"Environmental Remediation Liabilities." SOP 96-1 provides that environmental
remediation liabilities should be accrued when the criteria of FAS No. 5,
"Accounting for Contingencies," are met. It also provides that the accrual for
such liabilities should include future costs for those employees expected to
devote a significant amount of time directly to the remediation effort. The
adoption of SOP 96-1 reduced 1997 pretax income from continuing operations by
$49.9 million.
 
  In the fourth quarter of 1997, the Company began expensing process
reengineering costs (including $3.0 million previously capitalized) in
accordance with Emerging Issues Task Force consensus 97-13, reducing 1997 net
income by $1.9 million.
 
  Also in 1997, the Company began presenting earnings per share in accordance
with FAS No. 128. See Note 11 to Consolidated Financial Statements for further
discussion.
 
                                      40
<PAGE>
 
  In June 1997, the Financial Accounting Standards Board issued FAS No. 130,
"Reporting Comprehensive Income," and FAS No. 131, "Disclosure About Segments
of an Enterprise and Related Information." Both statements are effective for
fiscal years beginning after December 15, 1997, although FAS No. 131 does not
apply to the Company's interim financial statements until 1999. FAS No. 130
requires only a different format for presentation of information already
included in the Company's financial statements. FAS No. 131 modifies the basis
for determining segments and expands required disclosure, but does not affect
accounting principles and, accordingly, will not require any change to
reported financial position, results of operations or cash flows. The Company
is currently evaluating the impact of FAS No. 131 on its segment reporting.
 
DERIVATIVES AND MARKET RISKS
 
  In the normal course of business, the Company is exposed to market risk,
including changes in interest rates, currency exchange rates, certain
commodity prices and certain equity prices. From time to time, the Company and
certain of its subsidiaries use derivatives to manage some portion of these
risks. The derivatives used are simple agreements which provide for payments
based on the notional amount, with no multipliers or leverage. All derivatives
are related to actual or anticipated exposures or transactions of the Company.
While the Company is exposed to credit risk in the event of non-performance by
counterparties to derivatives, in all cases such counterparties are highly
rated financial institutions and the Company does not anticipate non-
performance. The Company does not hold or issue derivative financial
instruments for trading purposes. The Company monitors its derivative
positions by regularly evaluating the positions at market and by performing
sensitivity analyses.
 
  The Company has performed sensitivity analyses to determine how market rate
changes will affect the fair value of the Company's market risk sensitive
derivatives and related positions. Such an analysis is inherently limited in
that it represents a singular, hypothetical set of assumptions. Actual market
movements may vary significantly from the Company's assumptions. The effects
of such market movements may also directly or indirectly affect Company rights
and obligations not covered by the sensitivity analysis. Fair value
sensitivity is further not necessarily indicative of the ultimate cash flow or
earnings effect on the Company from the assumed market rate movements.
 
  Interest Rate Exposure. The Company's exposure to market risk for changes in
interest rates relates primarily to the Company's debt obligations, which are
mainly denominated in U.S. dollars. In addition, interest rate swaps are used
to lock-in or limit the variability in the interest expense of certain
floating rate debt obligations. An instantaneous, one percentage point decline
in interest rates across all maturities and applicable yield curves would
adversely affect the fair value of the Company's combined debt and interest
rate swap position by approximately $250 million. This analysis does not
reflect the effect that declining interest rates would have on other items
such as pension liabilities, nor the favorable impact they would have on
interest expense and cash payments for interest.
 
  Currency Rate Exposure. From time to time, the Company and certain of its
subsidiaries have used foreign currency derivatives to seek to mitigate the
impact of translation on foreign earnings and income from foreign investees.
Typically these derivatives have taken the form of purchased put options or
collars. There were no currency derivatives outstanding at December 31, 1997,
that relate to hedging the translation of foreign earnings.
 
  The Company occasionally incurs currency risk from cross border
transactions. When such transactions are anticipated or committed to, the
Company may enter into forward contracts or purchase options to reduce or
eliminate the related foreign exchange risk. The Company also incurs exchange
rate risk from borrowings denominated in foreign currencies. An instantaneous,
10 percent adverse movement in foreign exchange rates would affect the fair
value of the Company's foreign currency borrowings and foreign exchange hedges
at December 31, 1997, by approximately $30 million. The total effect on the
Company from movements in exchange rates will also be influenced by other
factors. For example, an increase in the fair value of foreign currency
denominated debt caused by exchange rate movements may be more than offset by
an increase in the value of the Company's net investment in foreign countries.

  Commodities Price Exposure. The Company operates a large fleet of vehicles
that require the purchase of a significant amount of diesel fuel. The Company
uses crude oil collars and swaps as a proxy to seek to mitigate the risk of
fluctuations in diesel fuel prices. The Company's fuel collars consist of a
call option or "cap" and a corresponding put option at a lower price or
"floor." The cap limits the Company's potential increased operating cost from
higher fuel prices whereas the floor limits the Company's potential cost
savings from a decline in fuel prices. Under its fuel swap agreements, the
Company collects payments from the swap counterparty when fuel prices average
above a certain reference price. When prices average below said reference
prices, the Company makes payments to the counterparty. All of the Company's
fuel hedges are cash settled. Quantities hedged do not exceed committed fuel
purchases or anticipated usage in any period. An instantaneous, 10 percent
decrease in the applicable reference price for hedges in place at December 31,
1997, would cause a fair value loss to the Company of approximately $6
million. The Company expects that these losses would be offset by savings from
buying fuel at prices below December 31, 1997, market prices.
 
  Equity Price Exposure. The Company occasionally obtains stock that it needs
to hold for a certain period of time. The Company sometimes seeks to mitigate
its market exposure to such holdings by entering into equity collars. Such a
collar consists of a "cap" that limits the Company's potential for gain from
appreciation in the stock price as well as a "floor" that limits the Company's
loss potential from a decline in the stock price. An instantaneous, 10 percent
decline in the price of the shares held by the Company at December 31, 1997,
would adversely affect the combined fair value of the stock and collar
positions by approximately $2 million.
 
  The Company is also further subject to equity price exposure from Company
debt issues that are convertible into the Company's common stock. These debt
issues had an aggregate carrying value of $494.5 million as of December 31,
1997. An instantaneous, 10 percent increase in the Company's stock price on
December 31, 1997, would increase the fair value of the Company's convertible
debt by approximately $23 million.

the use and accounting for derivative instruments. Also see "Financial
Condition--Capital Structure" for a discussion of the Company's sale of put
options in connection with its stock repurchase program.
 
ENVIRONMENTAL MATTERS
 
  The continuing business in which the Company is engaged is intrinsically
connected with the protection of the environment. As such, a significant
portion of the Company's operating costs and capital expenditures could be
characterized as costs of environmental protection. Such costs may increase in
the future as a result of legislation or regulation; however, the Company
believes that in general it tends to benefit when environmental regulation
increases, which may increase the demand for its services, and that it has the
resources and experience to manage environmental risk.
 
  As part of its ongoing operations, the Company provides for estimated
closure and post-closure monitoring costs over the operating life of disposal
sites as air space is consumed. The Company has also established procedures to
evaluate potential remedial liabilities at closed sites which it owns or
operated or to which it transported waste, including 89 sites listed on the
Superfund National Priority List ("NPL") as of December 31, 1997. Where the
Company concludes that it is probable that a liability has been incurred,
provision is made in the financial statements. See Note 8 to Consolidated
Financial Statements for additional information regarding the Company's
environmental liabilities.
 
  Estimates of the extent of the Company's degree of responsibility for a
particular site and the method and ultimate cost of remediation require a
number of assumptions and are inherently difficult, and the ultimate outcome
may differ from current estimates. However, the Company believes that its
extensive experience in the environmental services industry, as well as its
involvement with a large number of sites, provides a reasonable basis for
estimating its aggregate liability. As additional information becomes
available, estimates are adjusted as necessary. While the Company does not
anticipate that such adjustments would be material to its financial
 
                                      42
<PAGE>
 
statements, it is reasonably possible that technological, regulatory or
enforcement developments, the results of environmental studies, the existence
and ability of other potentially responsible third parties to contribute to
the settlements of such liabilities, or other factors could alter this
expectation and necessitate the recording of additional liabilities which
could be material.
 
  The Company spent, net of recoveries from other potentially responsible
parties, $71.5 million, $38.5 million, $69.8 million and $14.7 million on
remedial activities at closed sites in 1994, 1995, 1996, and 1997
respectively, and anticipates such net expenditures of approximately $57.3
million in 1998.
 
  The Company has filed suit against numerous insurance carriers seeking
reimbursement for past and future remedial, defense and tort claim costs at a
number of sites. Carriers involved in these matters have typically denied
coverage and are defending against the Company's claims. While the Company is
vigorously pursuing such claims, it regularly considers settlement
opportunities when appropriate terms are offered. Settlements received to date
($50.1 million in 1994, $38.2 million in 1995, $60.3 million in 1996, and
$94.3 million in 1997) have been included in operating expenses as an offset
to environmental expenses.
 
  From time to time, the Company and certain of its subsidiaries are named as
defendants in personal injury and property damage lawsuits, including
purported class actions, on the basis of a Company subsidiary's having owned,
operated or transported waste to disposal facilities which are alleged to have
contaminated the environment or, in certain cases, conducted environmental
remediation activities at such sites.
 
YEAR 2000 ISSUES
 
  Waste Management, like many other companies, expects to incur expenditures
to address the so-called "Year 2000" problem. The Year 2000 problem exists
because many computer systems and applications currently use two-digit data
fields to designate a year. As the century date change occurs, date-sensitive
systems will recognize the year 2000 as 1900, or not at all. This inability to
properly recognize or handle the year 2000 may cause systems to process
critical financial and operational information incorrectly, or to fail
completely.
 
  The reengineering of the finance and administrative processes, which the
Company began in 1996, includes new computer software which will be Year 2000
compliant, and will resolve the issue for many of the financial and
administrative systems. The Company's principal customer billing and customer
service systems are currently being remediated to comply with Year 2000
issues. To varying degrees, the Company has assessed and continues to assess
the impact of the Year 2000 issue on other systems, including those used by
its customer billing and customer service functions. The Company has not
completely identified its exposure to the Year 2000 issue, or formulated its
plans for addressing and resolving this issue in other systems, but expects to
be able to do so or to effectively work around unresolved problems in a timely
manner. The Company has established a Year 2000 program management office to
coordinate the efforts of its own staff of information technology
professionals and outside consultants engaged to reprogram, replace or test
software and related assets affected by the Year 2000 issue.
 
  The Company spent approximately $6.0 million in 1997 for Year 2000
modification of computer systems and estimates it will spend an additional $45
million in 1998 and 1999, excluding the cost of new hardware and software
which will be principally capitalized and is included in the capital budget.
The Company believes its contemplated actions will effectively address the
Year 2000 issue, but should that not be the case, a material disruption of its
business could result. Specific factors that might cause the Company not to be
able to address the Year 2000 issue effectively and that could influence the
amount and timing of future costs include, but are not limited to, the
availability and cost of personnel trained in this specialized area, the
nature and amount of programming required to upgrade and replace the affected
software, the ability to locate and correct all relevant computer codes, the
success of the Company's principal suppliers in addressing the Year 2000 issue
and similar uncertainties.

FINANCIAL CONDITION
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company had working capital deficits of $1,047.1 million, $280.9
million, and $2,046.9 million as of December 31, 1995, 1996, and 1997
respectively. The Company operates in a capital intensive service industry
with neither significant inventory nor seasonal variation in receivables, and
generates substantial cash from operating activities. As a result, emphasis is
placed on minimizing working capital requirements. The increase in working
capital between 1995 and 1996 is a result of lower current debt maturities,
strong cash flow, including the proceeds from the sale of a portion of the WTI
water business late in 1996, and the reclassification to current of the
investment in Wessex to be sold, partially offset by increased accruals for
losses on the sale of certain investments. The increase in working capital
deficit between 1996 and 1997 results primarily from lower levels of cash and
short-term investments ($451 million), higher levels of long-term debt payable
within one year ($995 million) and higher accrued expenses ($290 million)
related to loss contract provision reserves, increased self insurance reserves
and other reserves recorded as a result of the comprehensive review performed
by management. See Note 2 to Consolidated Financial Statements.
 
  Cash flow from operating activities, less capital expenditures (other than
acquisitions) and dividends, which the Company defines as "owners' cash flow,"
is available to meet current obligations, make acquisitions, reduce debt, or
repurchase common stock. Management has adopted a cash-driven financial
strategy including reduced capital spending and divestiture of non-core assets
and non-integrated businesses. Owners' cash flow was approximately $0.3
billion, $0.5 billion, $1.0 billion, and $1.8 billion in 1994 through 1997
respectively. The Company expects to generate approximately $400 million
during 1998 from the divestiture of certain non-core investments and non-
integrated businesses subject to constraints necessitated to meet pooling-of-
interests accounting treatment as required in the Merger with USA Waste. The
Company believes that it has adequate liquidity and resources to meet its
needs for replacement capital and finance anticipated growth. See "Capital
Structure."
 
  In February 1998, the credit ratings on the Company's senior unsecured long-
term debt were lowered to BBB by Standard & Poor's Rating Services and Baa3 by
Moody's Investors Service. Previously, the Company's debt was rated A- and
Baa1 by Standard & Poor's and Moody's, respectively. The lower credit ratings,
which are still investment grades, are not expected to have a material effect
on the Company's availability of long-term debt funding. These ratings are
independently issued by the rating agencies and are subject to change at any
time. On December 29, 1997 the Company put in place bank credit facilities
totalling $800 million for general corporate purposes including standby
liquidity for its commercial paper program. The facilities consist of a $550
million standby trade receivables sale agreement and a $250 million revolving
credit agreement, both of which expire June 30, 1998.
 
  The Company historically has met its short-term funding requirements through
the issuance of commercial paper in the public markets, with bank credit
facilities available as standby liquidity. In February 1998, Moody's lowered
its rating of the Company's commercial paper from Prime-2 ("P2") to Prime-3
("P3"), and there may be times when the Company is unable to issue sufficient
commercial paper to meet its needs. The market for A2/P3-rated commercial
paper is somewhat smaller than for higher-rated commercial paper. At such
times, the Company will fund its requirements using the bank credit facilities
which are in place and sufficient to meet such needs.
 
  In connection with the planned purchase of the remaining publicly held WTI
shares, the Company has entered into a commitment with the Chase Manhattan Bank
("Chase") whereby Chase, along with other financial institutions, has committed,
subject to the satisfaction of certain conditions, to provide new credit
facilities in the amount of $1.1 billion. The new credit facilities, which will
have a termination date of December 31, 1998 (subject to earlier termination in
the event of a change-in-control, including the Merger with USA Waste), will
provide the funding needed to complete the WTI transaction and replace the
Company's existing $250 million revolving credit facility. Additionally, the
termination date of the Company's $550 million standby trade receivables sale
agreement will be extended from June 30, 1998 to December 31, 1998.

ACQUISITIONS AND CAPITAL EXPENDITURES
 
  Capital expenditures, including $56.8 million, $154.1 million, $91.8 million
and $19.3 million for property and equipment of purchased businesses in 1994,
1995, 1996 and 1997, respectively, are shown in the following table:

  In 1994, the Company and its principal subsidiaries acquired 119 businesses
for $197.2 million in cash and notes, $17.3 million of debt assumed, 73,809
shares of Company common stock and 156,124 shares of WTI common stock. During
1995, 136 businesses were acquired for $224.3 million in cash and notes, $77.7
million of debt assumed, and 2.2 million shares of the Company's common stock.
In 1996, 83 businesses were acquired for $104.8 million in cash and notes,
$39.4 million of debt assumed, and approximately 8.2 million shares of the
Company's common stock. During 1997, 45 businesses were acquired for $51.4
million in cash and notes, $17.6 million of debt assumed, and 121,551 shares
of the Company's common stock.
 
  The Board of Directors has approved a capital expenditure budget of $1,300.0
million for 1998, excluding acquisitions, although the Merger Agreement with
USA Waste limits the Company's 1998 capital expenditures, excluding
acquisitions, to $1.2 billion. The increase in the 1998 capital expenditure
budget primarily reflects increased spending for vehicles resulting from the
adoption of a new fleet management strategy in the fourth quarter of 1997, as
well as an anticipated increase in spending for new information systems and
landfill cell construction. The Company currently expects to finance capital
expenditures through cash flow from operations and believes that it has
adequate resources to finance attractive acquisitions that become available.
 
CAPITAL STRUCTURE
 
  Although the Company has placed increasing emphasis on generating owners'
cash flow during 1994-1997, a substantial portion of such cash has been
returned to stockholders through stock repurchases. Debt to total capital
ratios were adversely impacted by the issuance of the subordinated notes
discussed below which were used to repurchase the publicly held shares of CWM
in 1995 and by the substantial reduction in stockholders' equity as a result
of common stock repurchases and losses sustained in 1996 and 1997. The
following table sets forth certain of the Company's leverage ratios:

  The above ratios include minority interest in subsidiaries and put options
as part of total capital.
 
  In January 1995, the Company acquired all of the approximately 21.4% of the
outstanding shares of CWM that it did not already own, in return for
convertible subordinated debt. In July 1995, Waste Management acquired the
approximately 3.1 million Rust shares held by the public for $16.35 per share
in cash. In June 1997, the Company announced an offer to acquire, for $15 per
share in cash, all of the approximately 53 million
 
                                      45
<PAGE>
 
outstanding shares of WTI it does not already own. The price was increased to
$16.50 per share pursuant to a definitive agreement subsequently negotiated
with a special committee of independent WTI directors. The terms of the
agreement have been approved by the WTI special committee and by the Boards of
Directors of the Company and WTI, but the transaction remains subject to the
approval of the holders of a majority of WTI's outstanding shares, other than
those held by the Company, voting on it at a special meeting of WTI
stockholders to be held March 30, 1998. In addition, this transaction is the
subject of several lawsuits which seek, among other things, to enjoin the
proposed transaction. The Company believes that it has met the legal standards
applicable to transactions of this type and intends to vigorously defend
itself in the lawsuits.
 
  The Boards of Directors of Waste Management and WTI had authorized their
respective companies to repurchase shares of their own common stock. Waste
Management repurchased 30 million shares through a "Dutch auction" tender
offer in the second quarter of 1997 but did not repurchase any other shares
that year. The Company does not at this time expect to repurchase any
additional shares of its own common stock. WTI repurchased 5.1 million shares
in the first six months of 1997 but terminated its repurchase activity
following the Waste Management offer to acquire the remaining publicly held
shares.
 
  During 1994 through 1996, in conjunction with its previously authorized
repurchase program, Waste Management sold put options on 42.3 million shares
of its common stock. The put options give the holders the right at maturity to
require the Company to repurchase its shares at specified prices. Proceeds
from the sale of put options were credited to additional paid-in capital. See
Note 10 to Consolidated Financial Statements for further information. There
were no put options outstanding at December 31, 1997, and the Company does not
at this time expect to sell additional options in the future.
 
  In 1994, the Company formed an Employee Stock Benefit Trust and sold 12.6
million shares of treasury stock to the Trust in return for a 30-year, 7.33%
note with interest payable quarterly and principal due at maturity. The
Company has agreed to contribute to the Trust each quarter funds sufficient,
when added to dividends on the shares held by the Trust, to pay interest on
the note as well as principal outstanding at maturity. At the direction of an
administrative committee composed of Company officers, the Trust will use the
shares or proceeds from the sale of the shares to pay employee benefits, and
to the extent of such payments by the Trust, the Company will forgive
principal and interest on the note.
 
RISKS AND UNCERTAINTIES
 
  During the first quarter of 1995, WM International received an assessment
from the Swedish Tax Authority of approximately 417 million Krona
(approximately $53 million) plus interest from the date of the assessment,
relating to a transaction completed in 1990. WM International believes that
all appropriate tax returns and disclosures were filed at the time of the
transaction and intends to vigorously contest the assessment.
 
  A Company subsidiary has been involved in litigation challenging a municipal
zoning ordinance which restricted the height of its New Milford, Connecticut,
landfill to a level below that allowed by the permit previously issued by the
Connecticut Department of Environmental Protection ("DEP"). Although a lower
Court had declared the zoning ordinance's height limitation unconstitutional,
during 1995 the Connecticut Supreme Court reversed this ruling and remanded
the case for further proceedings in the Superior Court. In November 1995, the
Superior Court ordered the subsidiary to apply for all governmental permits
needed to remove all waste above the height allowed by the zoning ordinance,
and the Connecticut Supreme Court has upheld that ruling. The Company is
complying with the order of the Superior Court while also seeking an
alternative resolution to this matter. The Company is unable to predict the
outcome of this matter at this time. Depending upon the nature of any plan
eventually approved by applicable regulatory authorities for removing the
waste, the actual volume of waste to be moved, and other currently
unforseeable factors, the subsidiary could incur costs which would have a
material adverse impact on the Company's results of operations in one or more
future periods.
 
  In May 1994, the U.S. Supreme Court ruled that state and local governments
may not constitutionally restrict the free movement of waste in interstate
commerce through the use of regulatory flow control laws. Such
 
                                      46
<PAGE>
 
laws typically involve a local government specifying a jurisdictional disposal
site for all solid waste generated within its borders. Since the ruling,
several decisions of state or federal courts have invalidated regulatory flow
control schemes in a number of jurisdictions. Other judicial decisions have
upheld non-regulatory means by which municipalities may effectively control
the flow of municipal solid waste. In addition, federal legislation has been
proposed, but not yet enacted, to effectively grandfather existing flow
control mandates. There can be no assurance that such alternatives to
regulatory flow control will in every case be found to be lawful or that such
legislation will be enacted into law.
 
  The Supreme Court's 1994 ruling and subsequent court decisions have not to
date had a material adverse affect on any of the Company's operations. In the
event that legislation to effectively grandfather existing flow control
mandates is not adopted, the Company believes that affected municipalities
will endeavor to implement alternative lawful means to continue controlling
the flow of waste. However, given the uncertainty surrounding the matter, it
is not possible to predict what impact, if any, it may have in the future on
the Company's disposal facilities, particularly WTI's trash-to-energy
facilities.
 
  WTI's Gloucester County, New Jersey, facility relies on a disposal franchise
for substantially all of its supply of municipal solid waste. On May 1, 1997,
the Third Circuit Court of Appeals ("Third Circuit") permanently enjoined the
State of New Jersey from enforcing its franchise system as a form of
unconstitutional solid waste flow control, but stayed the injunction for so
long as any appeals were pending. On November 10, 1997, the U.S. Supreme Court
announced its decision not to review the Third Circuit decision, thereby
ending the stay and, arguably, the facility's disposal franchise. The State
had continued to enforce flow control during the stay period. In light of the
current circumstances, the facility has lowered its prices and solicited new
customers. Under the reimbursement agreement between the project company that
owns the Gloucester facility and the bank that provides credit support to the
project, the termination of the waste franchise constitutes an event of
default. WTI and the credit support bank are presently disputing the
consequences of these developments.
 
  The New Jersey legislature has been considering various alternative
solutions, including a bill that provides for the payment and recovery of
bonded indebtedness incurred by counties, public authorities and certain
qualified private vendors in reliance on the State's franchise system. WTI
currently believes that, through either legislative action or a project
recapitalization, the Gloucester project can be restructured to operate, in
the absence of regulatory flow control, at a level of profitability which will
not result in a material adverse impact on consolidated results.
 
  Within the next several years, the air pollution control systems at certain
trash-to-energy facilities owned or leased by WTI will be required to be
modified to comply with more stringent air pollution control standards adopted
by the United States Environmental Protection Agency in December 1995 for
municipal waste combusters. The compliance dates will vary by facility, but
all affected facilities will be required to be in compliance with the new
rules by the end of the year 2000. Currently available technologies will be
adequate to meet the new standards. The total capital expenditures required
for such modifications are estimated to be in the $180-$220 million range. The
impacted facilities long-term waste supply agreements generally require that
customers pay, based on tonnage delivered, their proportionate share of
incremental capital, financing, and operating costs resulting from changes in
environmental regulations. Customer shares of capital and financing costs are
typically recovered over the remaining life of the waste supply agreements.
Pro rata operating costs are recovered in the period incurred. The Company
currently expects to recover approximately two-thirds of the incremental
expenditures incurred to comply with these stricter air emission standards.
 
  As the states and the U.S. Congress have accelerated their consideration of
ways in which economic efficiencies can be gained by deregulating the electric
generation industry, some have argued that over-market power sales agreements
entered into pursuant to the Public Utilities Regulatory Policies Act of 1978
("PURPA") should be voidable as "stranded assets." WTI's power production
facilities are qualifying facilities under PURPA and depend on the sanctity of
their power sales agreements for their economic viability. WTI believes that
federal law offers strong protections to its PURPA contracts, and recent state
and federal agency and court
 
                                      47

decisions have unanimously upheld the inviolate nature of these contracts.
While there is a risk that future utility restructurings, court decisions or
legislative or administrative action in this area could have an adverse effect
on its business, the Company currently believes such risk is remote.
 
  In the ordinary course of conducting its business, the Company becomes
involved in lawsuits, administrative proceedings and governmental
investigations, including antitrust and environmental matters and commercial
disputes. Some of these proceedings may result in fines, penalties or
judgments being assessed against the Company which, from time to time, may
have an impact on earnings for a particular quarter or year. The Company
believes it has adequately provided for such matters in its financial
statements and does not believe that their outcome, individually or in the
aggregate, will have a material adverse impact on its business or financial
condition.
 
  In November and December 1997, several alleged purchasers of the Company's
stock brought purported class action lawsuits against the Company and several
of its current and former officers in the United States District Court for the
Northern District of Illinois. Each of the lawsuits asserts that the
defendants violated the federal securities laws by issuing allegedly false and
misleading statements in 1996 and 1997 about the Company's financial condition
and results of operations. Among other things, the plaintiffs allege that the
Company employed accounting practices that were improper and that caused its
publicly-filed financial statements to be materially false and misleading. The
lawsuits demand, among other relief, unspecified monetary damages, attorneys'
fees, and the costs of conducting the litigation. The Company intends to
defend itself vigorously in this litigation. In January 1998, the fourteen
purported class actions were consolidated before one judge in the Northern
District of Illinois. Plaintiffs have until May 1998 to file a consolidated
amended complaint. It is not possible at this time to predict the impact this
litigation may have on the Company, although it is reasonably possible that
the outcome may have a materially adverse impact on its financial condition or
results of operations in one or more future periods.
 
  The Company is also aware that the Securities and Exchange Commission has
commenced a formal investigation with respect to the Company's previously
filed financial statements and related accounting policies, procedures and
system of internal controls. The Company intends to cooperate with such
investigation. The Company is unable to predict the outcome or impact of this
investigation at this time.
 
  A lawsuit by an alleged Company stockholder purporting to represent a class
of the Company's stockholders has been filed in the Chancery Court in and for
New Castle County, Delaware (although the Company has not yet been served)
against the Company and the members of its Board of Directors alleging
breaches of fiduciary duty by the defendants in connection with the Merger.
The lawsuit seeks, among other things, to have the transaction enjoined and to
recover unspecified damages. The Company believes the suit to be without merit
and intends to contest it vigorously.
 
  WM International operates facilities in Hong Kong which are owned by the
Hong Kong government. The Hong Kong economy has been impacted by the economic
uncertainty associated with many of the countries in the region. High and
volatile interest rates have resulted from speculation regarding its currency.
In addition to Hong Kong, WM International has operations in Indonesia and
Thailand. These countries have experienced illiquidity, volatile currency
exchange rates and interest rates, and reduced economic activity. WM
International, and therefore the Company, will be affected for the foreseeable
future by economic conditions in this region, although it is not possible to
determine the extent of such impact. At December 31, 1997, WM International
had a net investment of $107.5 million in these countries. Pretax income from
Hong Kong was $25.7 million in 1997. Income from Indonesia and Thailand has
not been significant to date.
 
OUTLOOK
 
  The Company believes that its current strategy and the actions it has taken
during 1997 and and thus far in 1998 position it for long-term growth and
improved profitability in a rapidly changing waste services market. However, a
number of challenges remain. Continued moderate economic growth is expected to
result in
 
                                      48
<PAGE>
 
relatively modest levels of solid waste volume growth and increasing
competition limits pricing opportunities somewhat. WTI has no new trash-to-
energy plants expected to come on-stream in the near future, and two of its
facilities will be negatively impacted by the renewal of existing contracts at
lower prices in 1998. The North American hazardous waste industry remains
depressed. Divestiture of discontinued and non-core businesses and
monetization of other assets must be completed, thereby allowing capital to be
redeployed.
 
  The Company is responding to these challenges with increased management
focus on its core waste management services business, improved productivity
through improved management practices and the use of technology, and greater
emphasis on generating cash and controlling capital expenditures. Management
has also adopted economic value added ("EVA(R)") as a key performance
measurement to guide its operations management to improve returns on invested
capital.
 
  The Company expects during 1998 that moderate revenue growth in the solid
waste business will be more than offset by divestitures, declines in hazardous
waste revenues and reduced pricing on two of WTI's long-term contracts. Cost
reduction efforts will be more than offset by increases in depreciation and
amortization expense, costs to implement key initiatives such as strategic
sourcing, fleet management and information systems, and costs associated with
the completion of the accounting review and related matters.
 
  For 1998, the Company expects its capital expenditures, exclusive of
acquisitions to increase to $1.2 billion as it accelerates the purchasing of
new collection vehicles in connection with its new fleet management strategy
and as it invests in new information systems to improve its financial,
administrative, marketing, sales and customer service processes. While the
decision to change its fleet management strategy will increase expenditures
for new collection vehicles by approximately $150 million in 1998 and $200
million in 1999, the Company anticipates maintenance and operating savings in
1999 and beyond of $20 million to $40 million per year.
 
  The Company will continue to seek to improve returns by leveraging its
network of assets and will also seek to enhance its position in current
markets with acquisitions that complement existing operations and resources.
At the same time, the Company will continue to dispose of non-core and non-
integrated businesses where returns are not satisfactory.
 
FORWARD-LOOKING INFORMATION.
 
  Except for historical data, the information herein constitutes forward-
looking statements. Forward-looking statements are inherently uncertain and
subject to risks. Such statements should be viewed with caution. Actual
results or experience could differ materially from the forward-looking
statements as a result of many factors, including failure of the Company to
complete the Merger with USA Waste, failure to achieve timely the cost savings
anticipated by the parties as a result of the Merger, changes in the price of
recyclable commodities, severe weather conditions, slowing of the overall
economy, higher interest rates, market risk associated with derivatives,
failure of the Company's restructuring plans to produce the cost savings
anticipated, the inability to complete the divestiture of discontinued
businesses or the monetization of other assets at appropriate prices and
terms. The Company makes no commitment to disclose any revisions to forward-
looking statements, or any facts, events or circumstances after the date
hereof, that may bear upon forward-looking statements.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholders and the Board of Directors of Waste Management, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Waste
Management, Inc. (a Delaware corporation) and Subsidiaries as of December 31,
1997, 1996 and 1995, and the related consolidated statements of income, cash
flows and stockholders' equity for each of the four years in the period ended
December 31, 1997 (1996 and prior as restated--See Note 2). 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 Waste Management, Inc. and
subsidiaries as of December 31, 1997, 1996 and 1995, and the results of their
operations and their cash flows for each of the four years in the period ended
December 31, 1997, in conformity with generally accepted accounting
principles.
 
  As discussed in Note 3 to the consolidated financial statements, effective
January 1, 1995, the Company changed its method of accounting for capitalized
interest on landfill cell construction and effective January 1, 1997, the
Company changed its method of accounting for environmental remediation
liabilities.
 
  Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. Schedule II (1996 and prior as
restated) listed in the index of financial statements 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.

NOTE 1. BUSINESS AND FINANCIAL STATEMENTS
 
  Waste Management, Inc. (formerly WMX Technologies, Inc.) and its
subsidiaries ("Waste Management" or the "Company") provide waste management
and related services to governmental, residential, commercial, and industrial
customers in the United States and in select international markets. The
Company previously provided process engineering and construction, specialty
contracting and industrial scaffolding services through its Rust International
Inc. ("Rust") subsidiary, water process systems, equipment manufacturing and
water and wastewater facility operations and privatization services through
its Wheelabrator Technologies Inc. ("WTI") subsidiary. As of December 31,
1997, WTI and Rust had sold all of these businesses, and accordingly they are
classified as discontinued operations in the accompanying financial
statements. The Company now operates in only the waste management services
industry. See Note 14 for details of certain financial information by
geographic area.
 
  The accompanying financial statements are prepared on a consolidated basis
and include the Company and its majority-owned subsidiaries. All significant
intercompany transactions and balances have been eliminated. Certain of the
Company's subsidiaries are restricted as to payment of dividends to the
Company. However, the Company has access to the net assets of such
subsidiaries through intercompany loans and advances.
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect reported amounts of assets, liabilities, income and
expenses and disclosures of contingencies. Future events could alter such
estimates in the near term.
 
NOTE 2. RESTATEMENT AND RECLASSIFICATION
 
  The Company has restated and reclassified its financial statements for each
of the three years ended December 31, 1996. The cumulative after-tax effect
for periods prior to January 1, 1994, has been reflected as a charge to
beginning retained earnings in the Consolidated Statements of Stockholders'
Equity. Unaudited quarterly financial data for the years 1995 and 1996 and the
first three quarters of 1997, as shown in Note 20, has also been restated and
reclassified. Except as otherwise stated herein, all information presented in
the Consolidated Financial Statements and related notes includes all such
restatements and reclassifications.
 
  As a result of a comprehensive review begun in the third quarter of 1997,
the Company determined that certain items of expense were incorrectly reported
in previously issued financial statements. These principally relate to
vehicle, equipment and container depreciation expense, capitalized interest
and income taxes. With respect to depreciation, the Company determined that
incorrect vehicle and container salvage values had been used, and errors had
been made in the expense calculations. The Company also concluded that
capitalized interest relating to landfill construction projects had been
misstated. On January 1, 1995, the Company changed its accounting for
capitalized interest (see "Capitalized Interest"), but the cumulative "catch-
up" charge was not properly recorded in the 1995 financial statements, and
errors were made in applying the new method in subsequent years. Capitalized
interest for 1995, 1996 and the first three quarters of 1997 has accordingly
been restated.
 
  The prior period restatements also include earlier recognition of certain
asset value impairments (primarily related to land, landfill and recycling
investments) and of environmental liabilities (primarily related to
remediation and landfill closure and post-closure expense accruals including
restatement of purchase accounting). The reduction of the special charge in
1996 is due primarily to the reversal of software impairment charges which
were recorded prematurely.

  In the fourth quarter of 1997, the Company reclassified the results of
certain Rust business units to continuing operations held for sale. These
businesses had previously been reported as discontinued operations. Accounting
standards require such reclassification because divestiture did not occur
within one year from the date the businesses were initially reported as
discontinued operations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The Company also reclassified certain items of income and expense in
previously issued financial statements. The primary effect of such
reclassification is to increase various expense categories by amounts which
had been offset against gains in sundry income. Such reclassifications, which
did not change net income, affected various line items within the Consolidated
Statements of Income.
 
  The effect of such reclassifications, and the restatements discussed above,
on the income statement line items, is shown in the following table:

NOTE 3. SUMMARY OF ACCOUNTING POLICIES
 
  Revenue Recognition. The Company is primarily in a service business and
recognizes revenue when services are performed. Results from long-term
contracts are recorded on the percentage-of-completion basis with losses
recognized in full when identified. Changes in project performance and
conditions, estimated profitability and final contract settlements may result
in future revisions to long-term contract costs and income.
 
  Foreign Currency. The functional currency of the majority of the Company's
foreign subsidiaries is the local currency of the country in which the
subsidiary operates. Accordingly, such subsidiaries' assets and liabilities
are translated at the rates of exchange at the balance sheet date while income
statement accounts are translated at the average exchange rates in effect
during the period. The resulting translation difference is charged or credited
directly to stockholders' equity, as revenues, expenses and cash flows of the
subsidiaries are primarily in their local currencies. Foreign exchange
transaction losses (income) (net of related income taxes and minority
interest) of $3.3 million, $2.2 million, $ 0.3 million and ($0.9) million are
included in the Consolidated Statements of Income for 1994, 1995, 1996, and
1997, respectively.
 
  Cash Equivalents. All highly liquid investments with maturities of three
months or less at date of purchase are considered to be cash equivalents.
 
  Short-Term Investments. As part of its cash management program, the Company
from time-to-time maintains a portfolio of marketable investment securities
($12.2 million, $11.0 million and $3.0 million at December 31, 1995, 1996 and
1997, respectively). The securities have an investment grade of not less than
A and a term to earliest maturity generally of less than one year, and include
tax exempt securities, certificates of deposit and Euro-dollar time deposits.
These securities are carried at cost.
 
  Short-term investments also include investments classified as "trading,"
which are carried at market price with unrealized gains and losses included in
Sundry Income. At December 31, 1996, this category included the shares of
Wessex Water Plc ("Wessex") (see Note 15). At December 31, 1997, this category
included certain other equity securities classified as "trading" as well as a
price collar related to such investment. These securities were delivered in
1998 in exchange for the cap price of the collar. See Note 7.
 
  Environmental Liabilities. The Company provides for estimated closure and
post-closure monitoring costs over the operating life of disposal sites as
airspace is consumed. The Company has also established procedures to evaluate
potential remedial liabilities at closed sites which it owns or operated, or
to which it transported waste, including 89 sites listed on the Superfund
National Priority List ("NPL"). When the Company concludes that it is probable
that a liability has been incurred, provision is made in the financial
statements, based upon management's judgment and prior experience, for the
Company's best estimate of the liability. Such estimates are subsequently
revised as deemed necessary as additional information becomes available. See
Note 8 for additional information.
 
  Contracts in Process. Information with respect to contracts in process
(which relate primarily to contracts involving a substantial construction
component) at December 31, 1995, 1996 and 1997, is as follows:

  All contracts in process are expected to be billed and collected within five
years.
 
  Accounts receivable includes retainage which has been billed, but which is
not due pursuant to contract provisions until completion. Such retainage at
December 31, 1997, is $5.3 million, including $1.1 million that is expected to
be collected after one year. Retainage was $8.0 million at December 31, 1996,
and $12.8 million at December 31, 1995.
 
  Property and Equipment. Property and equipment (including major repairs and
improvements) are capitalized and stated at cost. Items of an ordinary
maintenance or repair nature are charged directly to operations. Disposal
sites are carried at cost and to the extent the land component exceeds end use
realizable value, such excess is amortized over the estimated life of the
disposal site. Disposal site improvement costs are capitalized and charged to
operations over the shorter of the estimated usable life of the site or the
improvement.
 
  Preparation costs for individual secure land disposal cells are recorded as
land improvements. Cell costs are amortized as the airspace is filled.
Significant costs capitalized for such cells include excavation and grading
costs, costs relating to the design and construction of liner systems, and gas
collection and leachate collection systems.
 
  Depreciation and Amortization. The cost, less estimated salvage value for
certain types of assets, of property and equipment had been depreciated over
the following estimated useful lives on the straight-line method: buildings,
10 - 40 years; heavy collection vehicles, 10 - 12 years; other vehicles, 3 - 6
years; rolloff containers, 20 years; other containers, 15 years; machinery and
equipment, 3 - 20 years; leasehold improvements, over the life of the
applicable lease.
 
  Effective October 1, 1997, the Board of Directors approved a management
recommendation to revise the Company's North American collection fleet
management policy. Front-end loaders will be replaced after 8 years, and rear-
end loaders and rolloff trucks after 10 years. The previous policy was to not
replace front-end loaders before they were a minimum of 10 years old and other
heavy collection vehicles before they were a minimum of 12 years old. As a
result of this decision, the Company recognized an impairment writedown of
$70.9 million in the fourth quarter of 1997 for those vehicles scheduled for
replacement in the next two years under the new policy (see Note 16).
Depreciable lives have been adjusted commencing in the fourth quarter of 1997
to reflect the new policy. Also effective October 1, 1997, the Company reduced
depreciable lives on containers from 15 and 20 years to 12 years, and ceased
assigning salvage value in computing depreciation on North American collection
vehicles or containers. These changes in estimates increased depreciation
expense by $33.7 million in the fourth quarter of 1997.
 
  Also effective October 1, 1997, the Company changed its process for
estimating landfill lives. The Company now amortizes landfill costs over
estimated landfill capacity which includes permitted landfill airspace plus
expansions which are probable of being obtained in the next five years. The
Company's prior practice was to consider likely future expansions in the
amortization calculations, whether or not the permits were expected to be
obtained within the next five years. Factors in determining probable
expansions on a site-by-site basis include secured rights to required land,
status of legal, environmental, regulatory and political issues, and the
extent to which the permit application process has proceeded. This change in
estimate increased depreciation and amortization by $12.7 million and the
provision for closure and post-closure by $3.1 million in the fourth quarter
of 1997, and resulted in estimated landfill capacity declining from 2.9
billion cubic yards to 1.8 billion cubic yards.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  Intangible Assets. Intangible assets relating to acquired businesses consist
primarily of the cost of purchased businesses in excess of market value of net
assets acquired ("goodwill"). Such goodwill is amortized on a straight-line
basis over a period of not more than forty years. The accumulated amortization
of intangible assets amounted to $582.9 million, $685.8 million and $670.7
million as of December 31, 1995, 1996 and 1997, respectively.
 
  On an ongoing basis, the Company measures realizability of goodwill by the
ability of acquired businesses to generate current and expected future after-
tax operating income in excess of annual amortization. If such realizability
is in doubt, an adjustment is made to reduce the carrying value of the
goodwill.
 
  Capitalized Interest. Interest has been capitalized on significant
landfills, trash-to-energy plants and other projects under construction.
Amounts capitalized and netted against Interest Expense in the Consolidated
Statements of Income were $105.9 million in 1994, $43.9 million in 1995, $35.6
million in 1996, and $26.0 million in 1997.
 
  Effective January 1, 1995, the Company changed its method of capitalizing
interest on landfill cells. Previously, interest was capitalized using a
method that allocated construction costs incurred to airspace on a total
landfill basis. The new method uses as a base for interest capitalization the
discrete construction activities related to each cell and results in less
interest being capitalized. In a landfill disposal services market
characterized by substantial price competition and minimal anticipated volume
growth, the new method reduces the risk of an asset impairment in the future.
The change reduced 1995 net income from continuing operations by $20.0 million
or approximately $0.04 per share. The unaudited proforma effect of this change
to a preferable method, on 1994 and 1995 had the change been made as of
January 1, 1994, and excluding the cumulative effect of the accounting change,
is shown in the following table:

  Self-Insurance. The Company self-insures for auto, general liability and
workers' compensation claims up to $5 million per claim. Provision is made in
each accounting period for estimated losses, including losses incurred but not
reported, and related reserves are adjusted as additional claim information
becomes available. Claim reserves are discounted at 6%, 7% and 6% at December
31, 1995, 1996 and 1997, respectively, based on historical payment patterns.
The self-insurance reserve included in the accompanying balance sheet was
$151.7 million, $188.0 million and $226.7 million at December 31, 1995, 1996
and 1997, respectively.
 
  In the fourth quarter of 1997, the Company modified its self-insurance
reserve determination technique. The revised loss projection process improves
the estimation of future growth in claims. This change in estimate resulted in
a $56 million pre-tax charge.
 
  Derivative Financial Instruments. In the normal course of business, the
Company enters into a variety of derivative financial instruments to manage
currency, interest rate, commodity (fuel) and equity price risk. See Note 7 to
Consolidated Financial Statements for a description of these financial
instruments and the methods of accounting for them.

  Accounting Principles. Effective January 1, 1994, the Company adopted FAS
No. 112, "Employers' Accounting for Postemployment Benefits." The change
reduced 1994 net income by $1.3 million.
 
  Effective January 1, 1995, the Company changed its method of capitalizing
interest on landfill cell construction. See "Capitalized Interest." The
cumulative effect of this change reduced 1995 net income by $84.7 million.
 
  Effective January 1, 1996, the Company adopted FAS No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of." Impairments recorded prior to 1996 followed a methodology consistent with
FAS No. 121, and accordingly the adoption of this statement did not have a
material impact on the financial statements.
 
  FAS No. 123, "Accounting for Stock-Based Compensation," also became
effective in 1996. However, FAS No. 123 permitted compensation to continue to
be accounted for under Accounting Principles Board Opinion No. 25, and the
Company elected to follow this alternative. See Note 9.
 
  Effective January 1, 1997, the Company adopted American Institute of
Certified Public Accountants Statement of Position ("SOP") 96-1,
"Environmental Remediation Liabilities." SOP 96-1 provides that environmental
remediation liabilities should be accrued when the criteria of FAS No. 5,
"Accounting for Contingencies," are met. It also provides that the accrual for
such liabilities should include future costs for those employees expected to
devote a significant amount of time directly to the management of remediation
liabilities. The adoption of SOP 96-1 reduced 1997 pretax income by $49.9
million.
 
  In the fourth quarter of 1997, the Company began expensing process
reengineering costs (including $3.0 million previously capitalized) in
accordance with Emerging Issues Task Force consensus 97-13, reducing 1997 net
income by $1.9 million.
 
  Also in 1997, the Company began presenting earnings per share in accordance
with FAS No. 128. See Note 11 for further discussion.
 
  In June 1997, the Financial Accounting Standards Board issued FAS No. 130,
"Reporting Comprehensive Income," and FAS No. 131, "Disclosure About Segments
of an Enterprise and Related Information." Both statements are effective for
fiscal years beginning after December 15, 1997, although FAS No. 131 does not
apply to the Company's interim financial statements until 1999. FAS No. 130
requires only a different format for presentation of information already
included in the Company's financial statements. FAS No. 131 modifies the basis
for determining segments and expands required segment disclosure, but does not
affect accounting principles and, accordingly, will not require any change to
reported financial position, results of operations or cash flows. The Company
is currently evaluating the impact of FAS No. 131 on its segment reporting.

  The increased impact of non-deductible goodwill on the 1997 consolidated tax
provision is attributable to the asset impairment losses discussed in Note 16.
As a result of the 1997 comprehensive review, the Company increased deferred
tax valuation allowances and other tax reserves.

  Deferred income taxes result from the recognition in different periods of
revenue and expense for tax and financial statement purposes. The primary

  The Company's subsidiaries have approximately $13.0 million of alternative
minimum tax credit carryforwards that may be used indefinitely and capital
loss carryforwards of approximately $52.7 million with expiration dates
through 2002. Various subsidiaries have U.S. federal and foreign operating
loss carryforwards of approximately $514 million and state operating loss
carryforwards of approximately $601 million. Foreign operating losses of $481
million may be carried forward indefinitely; the remaining loss carryforwards
have expiration dates through the year 2012. Valuation allowances have been
established for uncertainties in realizing the benefits of tax loss and credit
carryforwards. While the Company expects to realize the deferred tax assets in
excess of the valuation allowances, changes in estimates of future taxable
income or in tax laws could alter this expectation. During 1995, the valuation
allowance increased, primarily for the uncertainty of realizing foreign
operating loss carryforwards. The valuation allowance decreased in 1996 by
approximately $20 million due primarily to the realization of capital loss
carryforwards and adjustments for certain operating loss carryforwards
previously estimated to be unrealizable. In 1997, the valuation allowance
increased approximately $102.7 million, composed of increases to allowances
due to the uncertainty of realizing alternative minimum tax credits, tax
benefits from certain asset impairment writedowns (primarily land), foreign
tax credits, and net operating loss carryforwards, partially offset by
reductions in allowances attributable primarily to foreign net operating loss
carryforwards.
 
  The Company has concluded that its foreign business requires that the
undistributed earnings of its foreign subsidiaries be reinvested indefinitely
outside the United States. If the reinvested earnings were to be remitted, the
U.S. income taxes due under current tax law would not be material.
 
NOTE 5. BUSINESS ACQUISITIONS AND DIVESTITURES
 
  In 1994, the Company and its principal subsidiaries acquired 119 businesses
for $197.2 million in cash and notes, $17.3 million of debt assumed, 73,809
shares of Company common stock and 156,124 shares of WTI common stock.
 
  During 1995, 136 businesses were acquired for $224.3 million in cash and
notes, $77.7 million of debt assumed, and 2.2 million shares of the Company's
common stock.
 
  In 1996, 83 businesses were acquired for $104.8 million in cash and notes,
$39.4 million of debt assumed, and 8.2 million shares of the Company's common
stock.

  During 1997, 45 businesses were acquired for $51.4 million in cash and
notes, assumed debt of $17.6 million, and 121,551 shares of the Company's
common stock.
 
  Three of the 1995 acquisitions, which otherwise met pooling of interests
criteria, were not significant in the aggregate and, consequently, prior
period financial statements were not restated. The remaining acquisitions were
accounted for as purchases. The pro forma effect of the acquisitions made
during the four years was not material.
 
  In January 1995, the Company acquired all of the approximately 21.4% of the
outstanding shares of CWM that it did not already own for $436.8 million of
convertible subordinated notes. See Note 6 for additional information. In July
1995, the Company acquired all of the approximately 3.1 million shares of Rust
held by the public, for $16.35 per share in cash.
 
  During 1997, the Company divested 24 solid waste operations in North America
for a total price of $288.9 million. The largest of these transactions was the
sale of most of its Canadian operations. Its Waste Management International
plc ("WM International") subsidiary sold substantially all of its remaining
operations in France for approximately $112 million, and its business in Spain
for approximately $16.3 million, and entered into an agreement for the sale
(completed in January 1998) of its Hamm, Germany waste-to-energy plant for
approximately $137.0 million.
 
  In June 1997, the Company announced an offer to acquire, for $15 per share
in cash, all of the approximately 53 million outstanding shares of WTI it does
not already own. The price was increased to $16.50 per share pursuant to a
definitive merger agreement subsequently negotiated with a special committee
of independent WTI directors. The terms of the agreement have been approved by
the WTI special committee and by the Boards of Directors of the Company and
WTI, but the transaction remains subject to the approval of the holders of a
majority of WTI's outstanding shares, other than those held by the Company,
voting on it at a special meeting of WTI stockholders to be held March 30,
1998. Several lawsuits have been filed which seek, among other things, to
enjoin the proposed transaction. The Company believes that it has met the
legal standards applicable to transactions of this type and intends to
vigorously defend itself in these lawsuits.

</TABLE>
 
  The LYONs, Exchangeable LYONs and CWM LYONs are redeemable at the option of
the holders on each June 30 until maturity, and the Exchangeable LYONs and the
CWM LYONs at the option of the Company at any time, at the issue price plus
accrued original issue discount to the date of redemption ($764.31, $429.86
and $474.09 per security, respectively, at December 31, 1997). Each LYON is
convertible into 34.88 shares of the Company's common stock at any time. The
Exchangeable LYONs and CWM LYONs are convertible as discussed below.
 
  In the Company's acquisition in 1995 of the outstanding CWM shares it did
not already own, the CWM public stockholders received a Subordinated Note,
with a principal amount at maturity of $1,000, for every 81.1 CWM shares held,
with cash paid in lieu of issuance of fractional notes. The notes are
subordinated to all existing and future senior indebtedness of Waste
Management. Each note bears cash interest at the rate of two percent per annum
of the $1,000 principal amount at maturity, payable semi-annually. The
difference between the principal amount at maturity of $1,000 and the $717.80
stated issue price of each note represents the stated discount. At the option
of the holder, each note will be purchased for cash by Waste Management on
March 15,

1998, and March 15, 2000, at prices of $789.95 and $843.03, respectively.
Accrued unpaid interest to those dates will also be paid. The notes will be
callable by Waste Management on and after March 15, 2000, for cash, at the
stated issue price plus accrued stated discount and accrued but unpaid
interest through the date of redemption. In addition, each note is convertible
at any time prior to maturity into 26.078 shares of Waste Management common
stock, subject to adjustment upon the occurrence of certain events. Upon any
such conversion, Waste Management will have the option of paying cash equal to
the market value of the Waste Management shares which would otherwise be
issuable. As of December 31, 1997, there were 549,404 such notes outstanding
with a maturity value amounting to $549.4 million.
 
  In connection with the Company's 1995 acquisition of the publicly held CWM
shares, CWM LYONs and Exchangeable LYONs which had been convertible into or
exchangeable for CWM shares became convertible into the number of notes
discussed in the preceding paragraph to which the holders would have been
entitled had they converted or exchanged the LYONs immediately prior to the
merger approval. As of December 31, 1997, the CWM LYONs and Exchangeable LYONs
were convertible or exchangeable into 8,332 and 4,695 Subordinated Notes,
respectively. Such Subordinated Notes in turn would be convertible into a
total of 339,718 shares of the Company's common stock.
 
  The securities described above and certain of the Company's other debt
instruments are redeemable at the option of the holders prior to maturity and,
accordingly, those which may be redeemed in 1998 are classified as current in
the accompanying financial statements at December 31, 1997. In prior years,
such borrowings were classified as long-term because the Company had committed
credit facilities in place to refinance them.
 
  The Company has in place committed standby trade receivables sale and
revolving credit facilities totaling $800 million with a group of six banks
led by Chase Manhattan Bank (the "Lenders") for general corporate purposes and
to support the Company's commercial paper program. The Lenders are committed
to fund up to $550 million, if requested by the Company, by purchasing
eligible receivables. Additionally, the Company has a $250 million unsecured
revolving credit agreement with the Lenders. Both facilities were put in place
in December 1997 and expire June 30, 1998. The facilities provide for
commitment fees ranging from 18.75 to 37.5 basis points per annum and interest
rates tied to prime or LIBOR plus a margin. Under the terms of the revolving
credit agreement as amended, the Company is required to maintain net worth of
$1.0 billion and consolidated debt (as defined in the agreement) not to exceed
3.5 times earnings (as defined in the agreement) before interest, taxes,
depreciation and amortization for the preceding four calendar quarters. As of
December 31, 1997, the Company was in compliance with such restrictions. The
Company had not obtained any funds under either facility as of February 24,
1998.
 
NOTE 7. DERIVATIVE FINANCIAL INSTRUMENTS
 
  From time to time, the Company and certain of its subsidiaries use
derivatives to manage interest rate, currency, commodity (fuel) and equity
price risk. The Company's policy is to use derivatives for risk management
purposes only, and it does not enter into such contracts for trading purposes.
The Company enters into derivatives only with counterparties which are
financial institutions having credit ratings of at least A- or A3, to minimize
credit risk. The amount of derivatives outstanding at any one point in time
and gains or losses from their use have not been and are not expected to be
material to the Company's financial statements.
 
  Instruments used as hedges must be effective at managing risk associated
with the exposure being hedged and must be designated as a hedge at the
inception of the contract. Accordingly, changes in market values of hedge
instruments must have a high degree of inverse correlation with changes in
market values or cash flows of underlying hedged items. Derivatives that meet
the hedge criteria are accounted for under the deferral or accrual method,
except for currency agreements as discussed below. If a derivative does not
meet or ceases to meet the aforementioned criteria, or if the designated
hedged item ceases to exist, then the Company subsequently uses
 
                                      74
<PAGE>
 
                    WASTE MANAGEMENT, INC. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
fair value accounting for the derivative, with gains or losses included in
sundry income. If a derivative is terminated early, any gain or loss,
including amounts previously deferred, is deferred and amortized over the
remaining life of the terminated contract or until the anticipated transaction
occurs.
 
  Interest Rate Agreements. Certain of the Company's subsidiaries have entered
into interest rate swap agreements to balance fixed and floating rate debt in
accordance with management's criteria. The agreements are contracts to
exchange fixed and floating interest rate payments periodically over a
specified term without the exchange of the underlying notional amounts. The
agreements provide only for the exchange of interest on the notional amounts
at the stated rates, with no multipliers or leverage. Differences paid or
received are accrued in the financial statements as a part of interest expense
on the underlying debt over the life of the agreements and the swap is not
recorded on the balance sheet or marked to market. As of December 31, 1997,
interest rate agreements in notional amounts and with terms as set forth in
the following table were outstanding:

</TABLE>
 
  Currency Agreements. From time to time, the Company and certain of its
subsidiaries use foreign currency derivatives to seek to mitigate the impact
of translation on foreign earnings and income from foreign investees.
Typically these have taken the form of purchased put options or collars. The
Company receives or pays, based on the notional amount of the option, the
difference between the average exchange rate of the hedged currency against
the base currency and the average (strike price) contained in the option.
Complex instruments involving multipliers or leverage are not used. Although
the purpose for using such derivatives is to mitigate currency risk, they do
not qualify for hedge accounting under generally accepted accounting
principles and accordingly, must be adjusted to market value at the end of
each accounting period with gains or losses included in sundry income. There
were no currency derivatives of this type outstanding at December 31, 1997.
 
  The Company sometimes also uses foreign currency forward contracts to hedge
committed transactions when the terms of such a transaction are known and
there is a high probability that the transaction will occur. At December 31,
1997, a subsidiary had sold Italian Lira forward for delivery in 1998 to hedge
foreign exchange exposure on a specific transaction. The amount was not
material to the consolidated financial statements, and any gain or loss will
be included in the measurement of the identified transaction.
 
  Commodity Agreements. The Company utilizes derivatives to seek to mitigate
the impact of fluctuations in the price of fuel used by its vehicles.
Quantities hedged do not exceed anticipated fuel purchases in any period.
Gains or losses are recognized in operating expenses, as cost of fuel
purchases, when paid or received. The primary instruments used are collars,
swaps and swaptions. Collars consist of the purchase of call options along
with a corresponding sale of put options at a lower price, with the effect of
establishing a "cap" and a "floor" with respect to the price of specified
quantities of fuel. A swap is an agreement with a counterparty whereby the
Company pays a fixed price and receives a floating price for specified
quantities during a given period. In a swaption, the Company is paid a premium
by the counterparty for the right, but not the obligation, at the end of the
option period (usually 90 to 180 days) to enter into a swap with respect to a
specified quantity in a given period in the future. The following table
summarizes the Company's position in crude oil derivatives at December 31,
1997:

  Equity Investments. The Company occasionally acquires common stock that it
needs to hold for a period of time. To mitigate its exposure to fluctuations
in the market price of such investments during the holding period, the Company
sometimes enters into hedging arrangements consisting of put options or
collars. Changes in the intrinsic value of such instruments are recorded in
stockholders' equity if the underlying stock is classified as "available for
sale" and in sundry income if it is classified as "trading." The offsetting
change in the value of the derivative is included in short term investments on
the balance sheet. At December 31, 1997, the Company had outstanding a collar,
which expired in 1998, on an investment in a publicly traded equity security.
The market price of the security was in excess of the cap value of the collar
at both December 31 and upon expiration, and accordingly, the Company
delivered the shares in exchange for the cap price, with no gain or loss
recognized in 1998.
 
  See Note 10 for a discussion of the Company's sale of put options in
connection with its authorized stock repurchase program.
 
NOTE 8. ENVIRONMENTAL COSTS AND LIABILITIES
 
  The continuing business in which the Company is engaged is intrinsically
connected with the protection of the environment. As such, a significant
portion of the Company's operating costs and capital expenditures could be
characterized as costs of environmental protection. Such costs may increase in
the future as a result of legislation or regulation, however, the Company
believes that in general it tends to benefit when environmental regulation
increases, which may increase the demand for its services, and that it has the
resources and experience to manage environmental risk.
 
  As part of its ongoing operations, the Company provides for estimated
closure and post-closure monitoring costs over the estimated operating life of
disposal sites as airspace is consumed. Such costs for U.S. landfills are
estimated based on the technical requirements of the Subtitle C and D
regulations of the U.S. Environmental Protection Agency or the applicable
state requirements, whichever are stricter, and include such items as final
cap and cover on the site, methane gas and leachate management, and
groundwater monitoring. Such costs for foreign landfills are estimated based
on compliance with local laws, regulations and customs.
 
  The Company has also established procedures to evaluate its potential
remedial liabilities at closed sites which it owns or operated, or to which it
transported waste, including 89 sites listed on the NPL. The majority of
situations involving NPL sites relate to allegations that subsidiaries of the
Company (or their predecessors) transported waste to the facilities in
question, often prior to the acquisition of such subsidiaries by the Company.
The Company routinely reviews and evaluates sites requiring remediation,
including NPL sites, giving consideration to the nature (e.g., owner,
operator, transporter, or generator), and the extent (e.g., amount and nature
of waste hauled to the location, number of years of site operation by the
Company, or other relevant factors) of the Company's alleged connection with
the site, the accuracy and strength of evidence connecting the Company to the
location, the number, connection and financial ability of other named and
unnamed potentially responsible parties ("PRPs"), and the nature and estimated
cost of the likely remedy. Cost estimates are based on management's judgment
and experience in remediating such sites for the Company as well as for
unrelated parties, information available from regulatory agencies as to costs
of remediation, and the number, financial resources and relative degree of
responsibility of other PRPs who are jointly and severally liable for
remediation of a specific site, as well as the typical allocation of costs
among PRPs. These estimates are sometimes a range of possible outcomes. In
such cases, the Company provides for the amount within the range which
constitutes its best estimate. If no amount within the range appears to be a
better estimate than any other amount, then the Company provides for the
minimum amount within the range in accordance with FAS No. 5. The Company
believes that it is "reasonably possible," as that term is defined in FAS No.
5 ("more than remote but less than likely"), that its potential liability, at
the high end of such ranges, would be approximately $201.9 million higher

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

on a discounted basis in the aggregate than the estimate that has been
recorded in the financial statements as of December 31, 1997.
 
  Estimates of the extent of the Company's degree of responsibility for
remediation of a particular site and the method and ultimate cost of
remediation require a number of assumptions and are inherently difficult, and
the ultimate outcome may differ from current estimates. However, the Company
believes that its extensive experience in the environmental services business,
as well as its involvement with a large number of sites, provides a reasonable
basis for estimating its aggregate liability. As additional information
becomes available, estimates are adjusted as necessary. While the Company does
not anticipate that any such adjustment would be material to its financial
statements, it is reasonably possible that technological, regulatory or
enforcement developments, the results of environmental studies, the existence
and ability of other potentially responsible third parties to contribute to
the settlements of such liabilities, or other factors could necessitate the
recording of additional liabilities which could be material.
 
  Where the Company believes that both the amount of a particular
environmental liability and the timing of the payments are reliably
determinable, the cost in current dollars is inflated at 3% until expected
time of payment and then discounted to present value at 6% (7% at December 31,
1995 and 1996). The portion of the Company's recorded environmental
liabilities that is not inflated or discounted was $440.9 million, $358.5
million and $344.7 million at December 31, 1995, 1996 and 1997, respectively.
Had the Company not discounted any portion of its liability, the amount
recorded would have been increased by approximately $368 million at December
31, 1997.
 
  As of December 31, the Company's liabilities for closure, post-closure
monitoring and environmental remediation costs were as follows:

  The decline between 1996 and 1997 in the expected aggregate undiscounted
amount is primarily due to a reduction in estimated airspace (see Note 3),
which correspondingly reduces closure and post-closure costs.

  In addition to the amounts above, at certain sites the Company has perpetual
care obligations aggregating $657,000 per year beginning in 2027.
 
  From time to time, the Company and certain of its subsidiaries are named as
defendants in personal injury and property damage lawsuits, including
purported class actions, on the basis of a Company subsidiary's having owned,
operated or transported waste to a disposal facility which is alleged to have
contaminated the environment or, in certain cases, conducted environmental
remediation activities at such sites. While the Company believes it has
meritorious defenses to these lawsuits, their ultimate resolution is often
substantially uncertain due to a number of factors, and it is possible such
matters could have a material adverse impact on the Company's earnings for one
or more quarters or years.
 
  The Company has filed suit against numerous insurance carriers seeking
reimbursement for past and future remedial, defense and tort claim costs at a
number of sites. Carriers involved in these matters have typically denied
coverage and are defending against the Company's claims. While the Company is
vigorously pursuing such claims, it regularly considers settlement
opportunities when appropriate terms are offered. Settlements to date ($50.1
million in 1994, $38.2 million in 1995, $60.3 million in 1996, and $94.3
million in 1997) have been included in operating expenses as an offset to
environmental expenses.
 
NOTE 9. STOCK OPTIONS
 
  The Company has two stock option plans currently in effect under which
future grants may be issued: the 1997 Waste Management, Inc. Equity Incentive
Plan (the "1997 Plan") and the 1992 Stock Option Plan for Non-Employee
Directors (the "Directors' Plan"). The plans provide for accelerated vesting
upon a "change in control" of the Company as defined in the plans.
 
  Options granted under the 1997 Plan are generally exercisable in three equal
cumulative installments beginning one year after the date of grant. Options
granted under the Directors' Plan become exercisable in five equal annual
installments beginning six months after the date of grant.
 
  Under the 1997 Plan, non-qualified stock options may be granted at a price
not less than 100% of the market value on the date of grant, for a term of not
more than ten years. Twenty-three million shares of the Company's common stock
were initially reserved for issuance under this plan.
 
  Pursuant to the Directors' Plan, 150,000 shares of the Company's common
stock were initially reserved. Options for a total of 15,000 shares are to be
granted, in five equal annual installments commencing with election to the
Board, to each person who is not an officer or full-time employee of the
Company or any of its subsidiaries.
 
  As part of the acquisitions of the CWM and Rust shares not previously owned
by the Company, as discussed in Note 5, outstanding CWM stock options were
converted into options to acquire approximately 2,873,000 Company shares at a
weighted-average price of $34.90 per share and outstanding Rust stock options
were converted into options to acquire approximately 1,976,000 Company shares
at a weighted-average price of $30.26 per share.

  As permitted by FAS No. 123, "Accounting for Stock-Based Compensation," the
Company has elected to continue to account for its employee stock option plans

  Commencing in 1996, the Company also made grants of restricted stock.
Compensation expense for grants of restricted shares is recognized ratably
over the vesting period (generally five to ten years) and amounted to $0.1
million and $2.4 million in 1996 and 1997, respectively. Unamortized
compensation expense related to grants of restricted stock was $11.1 million
at December 31, 1997.
 
NOTE 10. CAPITAL STOCK
 
  The Board of Directors has the authority to create and issue up to 50
million shares of $1 par preferred stock at such time or times, in such series
with such designations, preferences and relative participating, optional or
other special rights and qualifications, limitations or restrictions thereof
as it may determine. No shares of the preferred stock have been issued.
 
  The Boards of Directors of Waste Management and WTI have authorized their
respective companies to repurchase shares of their own common stock (up to 50
million shares in the case of Waste Management and 30 million shares in the
case WTI) in the open market, in privately negotiated transactions, or through
issuer tender offers. Both authorizations replaced prior common stock
repurchase authorizations. Waste Management repurchased 30 million shares
through a "Dutch auction" tender offer in the second quarter but has not
repurchased any other shares in 1997 and does not expect to conduct any
repurchases in 1998. WTI repurchased 5.1 million shares in the first six
months of 1997 but suspended its repurchase activity following the Waste
Management offer to acquire its remaining public shares.
 
  During 1994 through 1996, the Company sold put options on 42.3 million
shares of its common stock. The put options gave the holders the right at
maturity to require the Company to repurchase shares of its common stock at
specified prices. Proceeds from the sale of put options were credited to
additional paid-in capital. The amount the Company would be obligated to pay
to repurchase shares of its common stock if all outstanding put options were
exercised was reclassified to a temporary equity account. In the event the
options were exercised, the Company had the right to pay the holder in cash
the difference between the strike price and the market price of the Company's
shares, in lieu of repurchasing the stock.
 
  Options on 32.5 million shares expired unexercised, as the price of the
Company's stock was in excess of the strike price at maturity. The Company
repurchased 3.1 million shares of stock at a cost of $107.5 million, and 6.7
million options were settled for cash of $13.6 million. There were no put
options outstanding at December 31, 1997.

NOTE 11. EARNINGS PER SHARE
 
  In February 1997, the FASB issued FAS No. 128, "Earnings Per Share" ("EPS"),
which supersedes Accounting Principles Board Opinion No. 15. Primary EPS is
replaced by Basic EPS, which is computed by dividing income available to
common stockholders by the weighted average number of common shares
outstanding during the period. Fully diluted EPS is replaced by Diluted EPS
which gives effect to all dilutive potential common shares. The Company was
required to adopt FAS No. 128 in the fourth quarter of 1997. All prior periods
presented have been restated.
 
  Basic and Diluted (1997 diluted computations not shown as all potentially
issuable common shares are antidilutive) EPS from continuing operations are
computed as follows:

  Common shares potentially issuable upon conversion of CWM LYONs and
Exchangeable LYONs and exercise of stock options with exercise prices greater
than the average price of the Company's stock were not included in the
calculation of Diluted EPS in any year, nor were shares potentially issuable
with respect to Subordinated Notes or LYONs in 1996, because their effect is
antidilutive. In 1997 the Company had a loss from continuing operations and,
accordingly, no adjustment is made to Basic EPS because all potentially
issuable common shares would be antidilutive. At December 31, 1997, there were
37.4 million common shares potentially issuable with respect to stock options,
restricted shares and convertible debt, which could dilute Basic EPS in the
future. During 1997, the Company issued 1.2 million shares upon exercise of
stock options and conversion of debt.
 
NOTE 12. COMMITMENTS AND CONTINGENCIES
 
  The Company leases many of its operating and office facilities for various
terms. Rents charged to costs and expenses in the Consolidated Statements of
Income amounted to $177.2 million in 1994, $170.3 million in 1995, $164.5
million in 1996 and $159.7 million in 1997. These amounts include rents under
long-term leases, short-term cancelable leases and rents charged as a
percentage of revenue, but are exclusive of financing leases capitalized for
accounting purposes.

  The Company's insurance program includes coverage for pollution liability
resulting from "sudden and accidental" releases of contaminants and
pollutants. Management believes that the coverage terms, available limits of
liability, and costs currently offered by the insurance market do not
represent sufficient value to warrant the purchase of "non-sudden and
accidental" pollution liability insurance coverage. As such, the Company has
chosen not to purchase risk transfer "non-sudden and accidental" pollution
liability insurance coverage. To satisfy existing government requirements, the
Company has secured non-risk-transfer pollution liability insurance coverage
in amounts believed to be in compliance with federal and state law
requirements for "non-sudden and accidental" pollution. The Company must
reimburse the insurer for losses incurred and covered by this insurance
policy. In the event the Company continues not to purchase risk transfer "non-
sudden and accidental" pollution liability insurance coverage, net income
could be adversely affected in the future if "non-sudden and accidental"
pollution losses should occur.
 
  The Company has issued or is a party to approximately 3,370 bank letters of
credit, performance bonds and other guarantees. Such financial instruments
(averaging approximately $669,000 each), including those provided for
affiliates and not otherwise recorded, are given in the ordinary course of
business. A substantial portion of these performance bonds are issued by a
wholly-owned insurance company subsidiary, the sole business of which is to
issue such bonds to customers of the Company and its subsidiaries.
Approximately $277.7 million (at fair market value) of Company assets have
been contributed to this subsidiary to meet regulatory minimum capital
requirements. Because virtually no claims have been made against these
financial instruments in the past, management does not expect these
instruments will have a material adverse effect on the consolidated financial
position or results of operations of the Company.
 
  During the first quarter of 1995, WM International received an assessment
from the Swedish Tax Authority of approximately 417 million Krona
(approximately $53 million) plus interest from the date of the assessment,
relating to a transaction completed in 1990. WM International believes that
all appropriate tax returns and disclosures were properly filed at the time of
the transaction and intends to vigorously contest the assessment.
 
  A Company subsidiary has been involved in litigation challenging a municipal
zoning ordinance which restricted the height of its New Milford, Connecticut,
landfill to a level below that allowed by the permit previously issued by the
Connecticut Department of Environmental Protection ("DEP"). Although a lower
Court had declared the zoning ordinance's height limitation unconstitutional,
during 1995 the Connecticut Supreme Court reversed this ruling and remanded
the case for further proceedings in the Superior Court. In November 1995, the
Superior Court ordered the subsidiary to apply for all governmental permits
needed to remove all waste above the height allowed by the zoning ordinance,
and the Connecticut Supreme Court has upheld that ruling. The Company is
complying with the order of the Superior Court while also seeking an
alternative resolution to this matter. The Company is unable to predict the
outcome of this matter at this time. Depending upon the nature of any plan
eventually approved by applicable regulatory authorities for removing the
waste, the actual volume of waste to be moved, and other currently
unforseeable factors, the subsidiary could incur costs which would have a
material adverse impact on the Company's results of operations in one or more
future periods.

  In May 1994, the U.S. Supreme Court ruled that state and local governments
may not constitutionally restrict the free movement of trash in interstate
commerce through the use of regulatory flow control laws. Such laws typically
involve a local government specifying a jurisdictional disposal site for all
solid waste generated within its borders. Since the ruling, several decisions
of state or federal courts have invalidated regulatory flow control schemes in
a number of jurisdictions. Other judicial decisions have upheld non-regulatory
means by which municipalities may effectively control the flow of municipal
solid waste. In addition, federal legislation has been proposed, but not yet
enacted, to effectively grandfather existing flow control mandates. There can
be no assurance that such alternatives to regulatory flow control will in
every case be found to be lawful or that such legislation will be enacted into
law.
 
  The Supreme Court's 1994 ruling and subsequent court decisions have not to
date had a material adverse affect on any of the Company's operations. In the
event that legislation to effectively grandfather existing flow control
mandates is not adopted, the Company believes that affected municipalities
will endeavor to implement alternative lawful means to continue controlling
the flow of waste. However, given the uncertainty surrounding the matter, it
is not possible to predict what impact, if any, it may have in the future on
the Company's disposal facilities, particularly WTI's trash-to-energy
facilities.
 
  WTI's Gloucester County, New Jersey, facility has historically relied on a
disposal franchise for substantially all of its supply of municipal solid
waste. On May 1, 1997, the Third Circuit Court of Appeals ("Third Circuit")
permanently enjoined the State of New Jersey from enforcing its franchise
system as a form of unconstitutional solid waste flow control, but stayed the
injunction for so long as any appeals were pending. On November 10, 1997, the
U.S. Supreme Court announced its decision not to review the Third Circuit
decision, thereby ending the stay and, arguably, the facility's disposal
franchise. The State had continued to enforce flow control during the stay
period. In light of the current circumstances, the facility has lowered its
prices and solicited new customers. Under the reimbursement agreement between
the project company that owns the Gloucester facility and the bank that
provides credit support to the project, the termination of the waste franchise
constitutes an event of default. WTI and the credit support bank are presently
disputing the consequences of these developments.
 
  The New Jersey legislature has been considering various alternative
solutions, including a bill that provides for the payment and recovery of
bonded indebtedness incurred by counties, public authorities and certain
qualified private vendors in reliance on the State's franchise system. WTI
currently believes that, through either legislative action or a project
recapitalization, the Gloucester project can be restructured to operate, in
the absence of regulatory flow control, at a level of profitability which will
not result in a material adverse impact on consolidated results.
 
  Within the next several years, the air pollution control systems at certain
trash-to-energy facilities owned or leased by WTI will be required to be
modified to comply with more stringent air pollution control standards adopted
by the United States Environmental Protection Agency in December 1995 for
municipal waste combusters. The compliance dates will vary by facility, but
all affected facilities will be required to be in compliance with the new
rules by the end of the year 2000. Currently available technologies will be
adequate to meet the new standards. The total capital expenditures required
for such modifications are estimated to be in the $180-$220 million range. The
impacted facilities long-term waste supply agreements generally require that
customers pay, based on tonnage delivered, their proportionate share of
incremental capital, financing, and operating costs resulting from changes in
environmental regulations. Customer shares of capital and financing costs are
typically recovered over the remaining life of the waste supply agreements.
Pro rata operating costs are recovered in the period incurred. The Company
currently expects to recover approximately two-thirds of the incremental
expenditures incurred to comply with these stricter air emission standards.
 
  As the states and the U.S. Congress have accelerated their consideration of
ways in which economic efficiencies can be gained by deregulating the electric
generation industry, some have argued that over-market

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

power sales agreements entered into pursuant to the Public Utilities
Regulatory Policies Act of 1978 ("PURPA") should be voidable as "stranded
assets." WTI's power production facilities are qualifying facilities under
PURPA and depend on the sanctity of their power sales agreements for their
economic viability. WTI believes that federal law offers strong protections to
its PURPA contracts, and recent state and federal agency and court decisions
have unanimously upheld the inviolate nature of these contracts. While there
is a risk that future utility restructurings, court decisions or legislative
or administrative action in this area could have an adverse effect on its
business, the Company currently believes such risk is remote.
 
  In the ordinary course of conducting its business, the Company becomes
involved in lawsuits, administrative proceedings and governmental
investigations, including antitrust and environmental matters and commercial
disputes. Some of these proceedings may result in fines, penalties or
judgments being assessed against the Company which, from time to time, may
have an impact on earnings for a particular quarter or year. The Company
believes it has adequately provided for such matters in its financial
statements and does not believe that their outcome, individually or in the
aggregate, will have a material adverse impact on its financial condition or
results of operations.
 
  Several purported class action lawsuits and one purported derivative lawsuit
seeking injunctive relief and unspecified money damages were filed in the
Chancery Court in and for New Castle County, Delaware against the Company,
WTI, and individual directors of WTI in connection with the June 20, 1997
proposal by the Company to acquire all of the shares of WTI common stock which
the Company does not own. The Company has agreed to a merger in whch WTI's
stockholders would receive $16.50 in cash per share of WTI's common stock. The
lawsuits allege, among other things, that the defendants have breached
fiduciary duties to WTI's minority stockholders because the merger
consideration contemplated by the proposal was inadequate and unfair. In
addition, the purported derivative lawsuit alleges that the proposal was part
of a plan to misappropriate WTI's corporate opportunity to repurchase its own
shares. The Company believes that its actions and those of WTI and its Board
of Directors in connection with the proposal have been in accordance with
Delaware law. Accordingly, the Company intends to contest these lawsuits
vigorously.
 
  In November and December 1997, several alleged purchasers of the Company's
stock brought purported class action lawsuits against the Company and several
of its current and former officers in the United States District Court for the
Northern District of Illinois. Each of the lawsuits asserts that the
defendants violated the federal securities laws by issuing allegedly false and
misleading statements in 1996 and 1997 about the Company's financial condition
and results of operations. Among other things, the plaintiffs allege that the
Company employed accounting practices that were improper and that caused its
publicly-filed financial statements to be materially false and misleading. The
lawsuits demand, among other relief, unspecified monetary damages, attorneys'
fees, and the costs of conducting the litigation. The Company intends to
defend itself vigorously in this litigation. In January 1998, the fourteen
purported class actions were consolidated before one judge in the Northern
District of Illinois. Plaintiffs have until May 1998 to file a consolidated
amended complaint. It is not possible at this time to predict the impact this
litigation may have on the Company, although it is reasonably possible that
the outcome may have a materially adverse impact on its financial condition or
results of operations in one or more future periods. No provision has been
made in the Consolidated Financial Statements for future costs or liabilities,
if any, associated with this litigation.
 
  The Company is also aware that the Securities and Exchange Commission has
commenced a formal investigation with respect to the Company's previously
filed financial statements and related accounting policies, procedures and
system of internal controls. The Company intends to cooperate with such
investigation. The Company is unable to predict the outcome or impact of this
investigation at this time.
 
  A lawsuit by an alleged Company stockholder purporting to represent a class
of the Company's stockholders has been filed in the Chancery Court in and for
New Castle County, Delaware (although the Company has not yet been served)
against the Company and the members of its Board of Directors alleging
breaches of fiduciary duty by the defendants in connection with the Merger.
The lawsuit seeks, among other things, to have the

the suit to be without merit and intends to contest it vigorously.
 
NOTE 13. BENEFIT PLANS
 
  The Company has a qualified defined benefit pension plan for all eligible
non-union domestic employees of Waste Management, CWM and Waste Management of
North America, Inc. ("WMNA"). The benefits are based on the employee's years
of service and compensation during the highest five consecutive years out of
the last ten years of employment. The Company's funding policy is to
contribute annually an amount determined in consultation with its actuaries,
approximately equal to pension expense, except as may be limited by the
requirements of the Employee Retirement Income Security Act. An actuarial
valuation report is prepared for the plan as of September 30 each year and
used, as permitted by FAS No. 87, for the year-end disclosures.
 
  Net periodic pension expense for 1994 through 1997, based on discount rates
of 8.5%, 8.5%, 7.75% and 7.75%, respectively, included the following

  WM International participates in both defined benefit and defined
contribution retirement plans for its employees in various countries. The
projected benefit obligation, plan assets and unfunded liability of the WM
International defined benefit plans are not material. Other subsidiaries
participate in various multi-employer pension plans covering certain employees
not covered under the Company's pension plan, pursuant to agreements with
collective bargaining units who are members of such plans. These plans are
generally defined benefit plans; however, in many cases, specific benefit
levels are not negotiated with or known by the employer-contributors.
Contributions of $16.1 million, $18.3 million, $16.5 million and $18.6 million
for subsidiaries' defined benefit plans were made and charged to income in
1994, 1995, 1996 and 1997, respectively.
 
  Waste Management, WMNA and CWM provide postretirement health care benefits
to eligible employees, and WTI provides certain postretirement benefits other
than pensions to a limited number of former employees of a manufacturing
business it has sold. The following table analyzes the obligation for
postretirement benefits other than pensions (primarily health care costs),
measured as of December 31 of each year, which is included in other deferred

  For measurement purposes, a 7.5% annual rate of increase in the per capita
cost of covered health care claims was assumed for 1998; the rate was assumed
to decrease by 0.5% per year to 6.0% in 2001 and remain at that level
thereafter. Increasing the assumed health care cost trend by one percentage
point in each year would increase the accumulated postretirement benefit
obligation as of December 31, 1997 by approximately $4.0 million and the
aggregate of the service and interest cost components of net postretirement
health care cost for 1997 by approximately $0.3 million. The weighted-average
discount rate used in determining the accumulated postretirement benefit
obligation was 7.75% in 1995 and 1996 and 7.0% in 1997.
 
  The expense for postretirement health care benefits was as follows:

  The Company had an Employee Stock Ownership Plan ("1988 ESOP") for all
eligible non-union United States and Canadian employees of Waste Management,
CWM and WMNA. The benefits are based on the employee's years of service and
compensation. The Company contributes each year an amount, if any, determined
by the Board of Directors of the Company. This plan terminated December 31,
1997.

  The Company has a Profit Sharing and Savings Plan ("PSSP") available to
certain employees of Waste Management, Inc., CWM and WMNA. The terms of the
PSSP allow for annual contributions by the Company as determined by the Board
of Directors as well as a match of employee contributions up to $750 per
employee ($500 prior to January 1, 1996). Charges to operations for the PSSP
were $27.3 million in 1994, $24.9 million in 1995, $16.0 million in 1996 and
$17.9 million in 1997. Effective January 1, 1998, the plan was renamed the
"Retirement Savings Plan", the matching contribution formula was increased,
and the discretionary annual contribution was discontinued.
 
  Rust, WTI and WM International also sponsor non-contributory and
contributory defined contribution plans covering both salaried and hourly
employees. Employer contributions are generally based upon fixed amounts of
eligible compensation and amounted to $12.1 million, $13.6 million, $12.4
million and $19.1 million during 1994, 1995, 1996 and 1997, respectively.
 
  During 1994, the Company established an Employee Stock Benefit Trust and
sold 12.6 million shares of treasury stock to the Trust in return for a 30-
year, 7.33% note with interest payable quarterly and principal due at
maturity. The Company has agreed to contribute to the Trust each quarter funds
sufficient, when added to dividends on the shares held by the Trust, to pay
interest on the note as well as principal outstanding at maturity. At the
direction of an administrative committee comprised of Company officers, the
trustee will use the shares or proceeds from the sale of shares to pay
employee benefits, and to the extent of such payments by the Trust, the
Company will forgive principal and interest on the note. The shares of common
stock issued to the Trust are not considered to be outstanding in the
computation of earnings per share until the shares are utilized to fund
obligations for which the trust was established. Changes in the market value
of these shares are charged or credited to Additional Paid-In Capital.

NOTE 14. COMPANY'S OPERATIONS IN DIFFERENT GEOGRAPHIC AREAS
 
  As discussed in Note 1, the Company believes that all of its material
operations are part of the waste management services industry, and it
currently reports as a single industry segment. Foreign operations in 1997
were conducted in ten countries in Europe, seven countries in the Asia Pacific
region, and Canada, Mexico, Brazil, Israel and Argentina. However, during the
year, WMNA sold most of its Canadian operations, and WM International sold
substantially all of its operations in France, Spain and Austria. WM
International also learned in late September that its joint venture company's
bid to continue to provide waste collection and cleaning services to the City
of Buenos Aires, which represented a substantial portion of its business in
Argentina, was not successful.

  WM International operates facilities in Hong Kong which are owned by the
Hong Kong government. The Hong Kong economy has been impacted by the economic
uncertainty associated with many of the countries in the region. High and
volatile interest rates have resulted from speculation regarding its currency.
In addition to Hong Kong, WM International has operations in Indonesia and
Thailand. These countries have experienced illiquidity, volatile currency
exchange rates and interest rates, and reduced economic activity. WM
International, and therefore the Company, will be affected for the foreseeable
future by economic conditions in this region, although it is not possible to
determine the extent of such impact. At December 31, 1997, WM International
had a net investment of $107.5 million in these countries (including Hong
Kong). Pretax income from Hong Kong was $25.7 million in 1997. Income from
Indonesia and Thailand has not been significant to date.

NOTE 15. SPECIAL CHARGES
 
  In the first quarter of 1995, in response to the continuing deterioration of
the chemical waste services market, CWM realigned its organization, and in
connection therewith, recorded a special charge of $140.6 million before tax
($91.4 million after tax). The charge related primarily to a write-off of the
investment in facilities and technologies that CWM abandoned because they did
not meet customer service or performance objectives, but also includes $22.0
million of future cash payments for rents under non-cancelable leases,
guaranteed bank obligations of a joint venture, and employee severance. The
majority of the cash expenditures were paid in 1995, although certain of the
non-cancelable leases extend through the year 2002.
 
  In the fourth quarter of 1995, WM International recorded a special charge of
$194.6 million ($152.4 million after tax) primarily related to the actions it
had decided to take to sell or otherwise dispose of non-core businesses and
investments, as well as core businesses and investments in low potential
markets, abandon certain hazardous waste treatment and processing
technologies, and streamline its country management organization. The charge
reduced the Company's income by approximately $153.3 million before tax
($111.0 million after tax). The charge included $34.3 million of cash payments
for employee severance and rents under non-cancelable leases. Approximately
$11.2 million of the cash costs were paid in 1995. The majority of the balance
was paid in 1996, although certain rent payments on abandoned leased
facilities continue into the future.
 
  In the fourth quarter of 1996, WM International recorded a provision of
$77.0 million after tax related to the sale of its investment in Wessex and a
charge of $169.5 million after tax to revalue its investments in France,
Austria and Spain in contemplation of exiting all or part of these markets or
forming joint ventures. The charge also included the write-off of an
investment in a hazardous waste disposal facility in Germany because
regulatory changes adversely affected its volumes. These charges, primarily of
a non-cash nature, reduced the Company's income by $213.6 million after tax.
 
  Also, in the fourth quarter of 1996, Waste Management and CWM recorded
pretax charges of $154.1 million ($100.2 million after tax) for reengineering
their finance and administrative functions and increasing reserves for certain
litigation, including a dispute involving the computation of royalties on the
Emelle, Alabama, hazardous waste landfill. In December 1996, a federal court
in Memphis, Tennessee, held CWM liable for approximately $100.3 million in
damages to the former owners of the Emelle site. CWM is appealing the
decision. Any settlement of the Emelle litigation would be a cash payment, but
the timing is not currently estimable. The balance of the charge is primarily
non-cash, with $13.4 million of cash-related items paid mostly in 1997.
 
  In 1997, the Company recorded a special charge of $41.6 million (primarily
in the fourth quarter) for severance. Employees terminated were primarily
field operating management and related support personnel. Approximately $5.9
million of the severance had been paid by December 31, 1997, with the balance
being paid in 1998 and thereafter.
 
  WM International also recorded a special charge in 1997 ($104.4 million
before tax and minority interest) to reflect the costs of demobilization in
Argentina following loss of the contract renewal for the City of Buenos Aires,
divestiture or closure of underperforming businesses, primarily in Italy and
Germany and the writeoff of costs of projects, primarily in Germany, which it
decided to no longer pursue. The charge included $14.8 million of severance,
primarily related to operating personnel in Buenos Aires and with closed or
divested businesses in Italy and Germany. These terminations are expected to
occur and the severance paid in 1998.

NOTE 16. ASSET IMPAIRMENT LOSS
 
  As a result of the comprehensive review of operating assets and investments
discussed in Note 2, the Company recorded an impairment loss of $1,401.2
million in the fourth quarter of 1997, and restated prior financial statements
to retroactively recognize impairment losses in earlier periods. Fair values
were determined for landfills, hazardous waste facilities, recycling
investments and other facilities, primarily based on future cashflow
projections discounted back using discount rates appropriate for the risks
involved with the specific assets. For surplus real estate, market opinions
and appraisals were used. In determining fair values for abandoned projects
and vehicles to be sold, recoverable salvage values were determined using
market estimates. The losses related to the following asset categories:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  Impaired assets to be sold are primarily businesses to be sold (see Note 17)
and surplus real estate. The carrying amount of such real estate was $73.3
million at December 31, 1997. The Company is currently marketing these
properties; however, since the disposal date cannot be accurately estimated,
these assets are classified as long-term assets in the accompanying balance
sheet at December 31, 1997.
 
NOTE 17. DISCONTINUED OPERATIONS
 
  In the fourth quarter of 1995, the Rust Board of Directors approved a plan
to sell or otherwise discontinue Rust's process engineering, construction,
specialty contracting and similar lines of business. During the second quarter
of 1996, the sale of the industrial process engineering and construction
businesses, based in Birmingham, Alabama, was completed.
 
  During the fourth quarter of 1996, WTI sold its water process systems and
equipment manufacturing businesses. WTI had also entered into an agreement to
sell its water and wastewater facility operations and privatization business,
which was sold in 1997. As of September 30, 1996, Rust sold its industrial
scaffolding business and began implementing plans to exit its remaining
international engineering and consulting business. Waste Management recorded a
fourth-quarter provision for loss of $360.0 million before tax and minority
interest in connection with the planned divestiture of these businesses, and
others subsequently reclassified to continuing operations (see discussion
below).
 
  The discontinued businesses have been segregated and the accompanying
consolidated balance sheets, statements of income and related footnote
information have been restated. Revenues from the discontinued businesses were
$1,186.5 million in 1994, $1,511.0 million in 1995, $734.5 million for 1996
and $84.8 million in 1997. The decreases in revenue during the periods
primarily reflect the sales of certain of the discontinued businesses. Results
of their operations in 1997 were not material and were included in the reserve
for loss on disposition provided previously.
 
  The following table summarizes the assets and liabilities as of December 31,
1995 and 1996, which are reflected on the consolidated balance sheet as net
assets of discontinued operations. The Company had no operations classified as
discontinued as of December 31, 1997.

  At December 31, 1996, management also classified as discontinued and planned
to sell Rust's domestic environmental and infrastructure engineering and
consulting business and CWM's high organic waste fuel blending services
business. In 1997, management reclassified the CWM business back into
continuing operations, and classified certain of its sites as operations held
for sale. The Rust disposition was not completed within one year, and
accordingly this business has been reclassified back into continuing
operations, as operations held for sale, at December 31, 1997, in accordance
with generally accepted accounting principles, although management is
continuing its efforts to market its investment in this business. As these
businesses were reclassified to continuing operations, the remaining provision
for loss on disposal ($95 million after tax--$87 million related to Rust and
$8 million related to CWM) was reversed in discontinued operations and an
impairment loss for Rust

NOTE 18. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
  The following disclosure of the estimated fair value of financial
instruments is made in accordance with the requirements of FAS No. 107,
"Disclosures about Fair Value of Financial Instruments." The estimated fair
value amounts have been determined by the Company, using available market
information and commonly accepted valuation methodologies. However,
considerable judgment is necessarily required in interpreting market data to
develop the estimates of fair value. Accordingly, the estimates presented
herein are not necessarily indicative of the amounts that the Company or
holders of the instruments could realize in a current market exchange. The use
of different assumptions and/or estimation methodologies may have a material
effect on the estimated fair value amounts. The fair value estimates presented
herein are based on information available to management as of December 31,
1995, 1996, and 1997. Such amounts have not been revalued since those dates,
and current estimates of fair value may differ significantly from the amounts
presented herein.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  Cash, Receivables and Investment. The carrying amounts of these items are a
reasonable estimate of their fair value.
 
  Liabilities. For debt issues that are publicly traded, fair values are based
on quoted market prices or dealer quotes. Due to the short-term nature of the
ESOP notes, their carrying value approximates fair value. Interest rates that
are currently available to the Company for issuance of debt with similar terms
and remaining maturities are used to estimate fair value for debt issues that
are not quoted on an exchange.
 
  Derivatives. The fair value of derivatives generally reflects the estimated
amounts that the Company would receive or pay to terminate the contracts at
December 31, thereby taking into account unrealized gains and losses. Dealer
quotes are available for most of the Company's derivatives. Unrealized gains
and losses are shown as assets and liabilities, as offsetting such amounts
against the related nonderivative instrument is permitted only pursuant to a
right of setoff or master netting agreement.
 
  Off-Balance-Sheet Financial Instruments. In the normal course of business,
the Company is a party to financial instruments with off-balance-sheet risk,
such as bank letters of credit, performance bonds and other guarantees, which
are not reflected in the accompanying consolidated balance sheets. Such
financial instruments are to be valued based on the amount of exposure under
the instrument and the likelihood of performance being required. In the
Company's experience, virtually no claims have been made against these
financial instruments. Management does not expect any material losses to
result from these off-balance-sheet instruments and, therefore, is of the
opinion that the fair value of these instruments is zero.
 
NOTE 19. SUBSEQUENT EVENTS
 
  On March 10, 1998, the Company entered into a definitive merger agreement
(the "Merger Agreement") with USA Waste Services, Inc. ("USA Waste") pursuant
to which the Company will be merged with a wholly-owned subsidiary of USA
Waste (the "Merger"). Pursuant to the Merger Agreement, the Company's
stockholders will receive .725 shares of common stock of USA Waste for each
share of common stock of the Company. The consummation of the Merger is
subject to a number of conditions, including the expiration or termination of
the applicable merger review waiting period under the Hart-Scott-Rodino Anti-
Trust Improvements Act of 1976, approval by the stockholders of each company
and other closing conditions. In addition, the Merger is contingent upon the
transaction qualifying for pooling-of-interests accounting treatment. In order
to qualify for pooling-of-interests accounting treatment, the Company intends
to sell a portion of its treasury shares pursuant to a registered public
offering prior to the closing of the Merger. A lawsuit by an alleged Company
stockholder purporting to represent a class of the Company's stockholders has
been filed (although the Company has not yet been served) against the Company
and the members of its Board of Directors alleging breaches of fiduciary duty
by the defendants in connection with the Merger. The lawsuit seeks, among
other things, to have the transaction enjoined and to recover unspecified
damages. The Company believes the suit to be without merit and intends to
contest it vigorously.
 
  Upon the consummation of the Merger, certain long-term debt of WM
International may be accelerated and become payable with three months notice.
At December 31, 1997, this debt totalled approximately $209 million, however,
by March 17, 1998 it had been reduced to $71 million. In addition, Wessex has
an option to acquire WM International's ownership in its United Kingdom
business at fair market value that may become exercisable upon the
consummation of the Merger. In 1997, this business had revenues of
approximately $276 million and operating income (before minority interest) of
approximately $25 million. WM International had a net investment of
approximately $315 million in the business at December 31, 1997.
 
  The Company may have other "change of control" provisions in customer and
employee contracts or agreements, governmental franchises or facility permits
that may be triggered by the closing of the proposed Merger. The Company is
currently in the process of reviewing these contracts, franchises and permits,
but does not expect at this time that the effect of these provisions, in the
event they are triggered by the Merger, will have a material adverse effect on
future results of operations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  On March 15, 1998, approximately $2.5 million face amount of Subordinated
Notes (see Note 6) were submitted for redemption by the holders in accordance
with their terms. The next optional redemption date is March 15, 2000, and
accordingly the remaining outstanding Subordinated Notes will be classified as
long-term as of March 31, 1998.
 
  In connection with the planned purchase of the remaining publicly held WTI
shares, the Company has entered into a commitment with the Chase Manhattan
Bank ("Chase") whereby Chase, along with other financial institutions, has
committed, subject to the satisfaction of certain conditions, to provide new
credit facilities in the amount of $1.1 billion. The new credit facilities,
which will have a termination date of December 31, 1998 (subject to earlier
termination in the event of a change-in-control, including the Merger with USA
Waste), will provide the funding needed to complete the WTI transaction and
replace the Company's existing $250 million revolving credit facility.
Additionally, the termination date of the Company's $550 million standby trade
receivables sale agreement will be extended from June 30, 1998 to December 31,
1998.

  The following is an analysis of certain items in the Consolidated Statements
Income, as restated and reclassified (see Note 2), by quarter for 1995, 1996,
and 1997. Sum of per share amounts for the quarters does not always equal the
full year amount due to rounding and, in the case of Diluted EPS, the method
of calculation prescribed by FAS No. 128. See Note 15 for a discussion of
special charges, Note 16 for a discussion of the asset impairment losses, and

(1) The option holder has the right to pay the exercise price by delivering
    previously acquired shares of the Company's common stock, and to have
    shares withheld to satisfy tax withholding requirements in connection with
    the exercise of options. Such options become immediately exercisable upon
    a Change in Control of the Company, as defined in the option plan. Options
    are non-transferable other than by will or the laws of descent and
    distribution.
 
(2) Options become exercisable May 9, 1998.
 
(3) Options become exercisable upon termination of service.
 
(4) Options become exercisable in three equal cumulative annual installments
    commencing March 4, 1998.
 
(5) Options become exercisable in three equal cumulative annual installments
    commencing May 9, 1998.
 
(6) Options become exercisable in three equal cumulative installments
    commencing June 20, 1998.
 
(7) Options have a term of ten years, subject to earlier termination in
    certain events related to termination of employment. Mr. LeMay's options
    terminated upon his resignation. Mr. Koenig's options terminate on October
    31, 2000.
 
(8) The amounts under the columns labeled "5%" and "10%" are included by the
    Company pursuant to certain rules promulgated by the Securities and
    Exchange Commission and are not intended to forecast future appreciation,
    if any, in the price of the Company's stock. Such amounts are based on the
    assumption that the named persons hold the options granted for their full
    term. The actual value of the options will vary
 
                                      104
<PAGE>
 
   in accordance with the market price of the Company's common stock. The
   column headed "0%" is included to demonstrate that the options were granted
   at fair market value and optionees will not recognize any gain without an
   increase in the stock price, which increase benefits all stockholders
   commensurately.
 
(9) Based upon the price of the Company's stock and the total shares
    outstanding as of the date of grant, if the price of the Company's common
    stock increased at the 5% or 10% rates shown in the table above,
    stockholders as a group would realize aggregate gains (excluding
    dividends) in the amounts shown above during the period from grant date to
    the May 9, 2007 option expiration date.
 
  The following table sets forth certain information as to each exercise of
stock options during the year ended December 31, 1997 by the persons named in

(1) Awards consist of the designation of target percentages of annual salary
    at the end of the performance period to be paid if the Company achieves
    certain performance objectives. No payout occurs unless the Company
    achieves certain threshold performance objectives. Above the threshold,
    payouts may be greater than the target percentage to the extent that the
    Company's performance exceeds or fails to meet the target objectives
    specified in the plan. Payouts under the LTIP are based on the rank of the
    Company's total stockholder return (stock price appreciation plus
    reinvested dividends) among the total stockholder returns of the companies
    that comprise the Dow Jones Industrial Average over the performance
    period.
(2) The performance period includes calendar years 1997, 1998 and 1999.
(3) Provided that the participant is an officer of the Company or one of its
    subsidiaries at the end of the performance period, an amount equal to 50%
    of the performance award, if any, is to be paid in cash, and the remaining
    50% is to be deemed to be invested in common stock of the Company. The
    participant is entitled to receive the value of such deemed investment on
    the date three years after the end of the performance period. Estimated
    future payouts were calculated using 1997 salaries, assume that a
    performance award will be earned at the levels shown, and do not reflect
    any possible subsequent increase or decrease in the value of the portion
    of the award which would be required to be deferred under the terms of the
    plan.

(1) Upon normal retirement at age 65 or after completing five years of
    participation in the Company's Pension Plan, whichever is later, a
    participant is entitled to a pension based on the average of the
    participant's eligible compensation for the highest five consecutive years
    out of his or her last 10 years of service. For this purpose, a
    participant's eligible compensation generally includes all of his or her
    cash compensation, subject, in 1997, to the statutory maximum of $160,000.
    The annual lifetime benefit is equal to (i) 1% of average eligible
    compensation, multiplied by (ii) the number of his or her years of
    service, and, for a participant retiring at age 65 with 10 years of
    service, may not be less than $100 per month. Under the SERP, eligible
    participants who retire following age 60, or retire with at least 30 years
    of service, are entitled to a monthly benefit equal to (i) 1.5% of the
    participant's Final Average Compensation per year of service (Final
    Average Compensation is the monthly average compensation of such
    participant for the highest three consecutive calendar years out of his or
    her last 10 calendar years of service), reduced by (ii) the amount of such
    participant's monthly benefit under the Pension Plan. Compensation used
    for calculating benefits under the SERP includes only the participant's
    salary and annual incentive bonus. Eligible participants are those
    officers who have served in such capacities for at least 10 years at the
    time of retirement. Payment of benefits under the SERP is made on the same
    basis as payments under the Pension Plan, and both plans provide for
    reduced payouts in the event of early retirement.
(2) At December 31, 1997, the credited years of service for current and former
    executive officers were as follows: Mr. Miller--0; Mr. Buntrock--41; Mr.
    LeMay--0; Mr. Rooney--28; Mr. Caudle--22; Mr. Getz--14; Mr. Koenig--20;
    Mr. Hulligan--19; Mr. Holsten--15; Mr. Payne--7.

(3) Benefits shown are computed on a straight-life annuity basis at normal
    retirement age. Provision is made for payment of pensions in joint and
    survivor form and in various other forms and at other times, on an
    actuarially equivalent basis. Benefits are not subject to reduction for
    social security benefits.
 
COMPENSATION OF DIRECTORS
 
  Each member of the Board of Directors of the Company who is not an employee
of the Company is paid an annual retainer of $50,000, 50% of which is paid in
shares of restricted common stock of the Company. Such directors also receive
$1,000 for each day on which they perform substantial work on behalf of a
Committee of the Board, which includes attendance at meetings of Committees of
which such directors are members. Each director is expected to accumulate,
over a five year period, an equity interest in the Company equivalent to 300%
of the annual retainer for Board service. Directors may elect to receive 100%
of their retainer in the form of restricted common stock of the Company.
Directors who have met or exceeded the Board's minimum stock ownership goal
may elect to receive up to 100% of their annual retainer in cash. The Company
maintains a major medical expense insurance policy which is available to all
directors of the Company. The policy covers the medical and dental expenses of
the directors in excess of the coverage provided by the director's primary
health insurance program.
 
OUTSIDE DIRECTORS' PLANS
 
  The Company has two unfunded deferred compensation plans for non-employee
members of its Board of Directors. Under the Deferred Directors' Fee Plan, as
amended, such directors may make an irrevocable election annually to defer
receipt of all or a portion of the directors' fees payable to them until
termination of their membership on the Board of Directors. Such amounts
deferred prior to January 1, 1998 are deemed to be invested in the Company's
common stock or, at the election of the director, in the common stock of any
of the Company's majority-owned public subsidiaries, and during the period of
deferral, such deferred amounts are credited with the dividends or stock
splits that would be received had such investment actually been made. Upon
termination of the director's service, the common stock deemed reflected by
his or her deferred account is deemed to be sold, and the deemed proceeds of
such sale (or an amount equal to the amount originally deferred, if greater)
will be distributed to the director in cash, in a lump sum or installments.
Accounts deferred after December 31, 1997 will be credited with interest from
time to time at a rate equal to the weekly average rate on the ten year U.S.
Treasury Note. Upon termination of the director's service, the value of the
account on the books of the Company will be distributed to the director in
cash, in a lump sum or installments.
 
  Under the Directors' Phantom Stock Plan, certain non-employee directors
received a one-time grant of 5,000 Phantom Shares at the time of adoption of
such plan or at the time they first became directors. Each of such Phantom
Shares was initially deemed to be equal in value to one share of the Company's
common stock at the time of award. Phantom Shares are credited to a
bookkeeping account which is adjusted to reflect stock (but not cash)
dividends or stock splits which would be received with respect to an
equivalent number of shares of the Company's common stock. Upon termination of
the director's service, the director is paid an amount in cash, in a lump sum
or installments, for each Phantom Share then credited to his or her account,
equal to the then difference between the market price of the Company's common
stock at the time of award and the average closing prices of one share of the
Company's common stock on the New York Stock Exchange Composite Tape for the
most recent 10 consecutive trading days immediately preceding such
termination. In 1991, the Company's Board of Directors terminated its
authority to make additional grants under the Directors' Phantom Stock Plan.
 
STOCK OPTION PLANS FOR NON-EMPLOYEE DIRECTORS
 
  The 1992 Stock Option Plan for Non-Employee Directors (the "Directors Plan")
of the Company provides for the awards of options covering an aggregate of
150,000 shares of the Company's common stock. Each director of the Company
first elected in 1997 or thereafter who is neither an officer nor full-time
employee of the Company or any of its subsidiaries, upon election or
appointment to the Board of Directors, is granted an option to purchase 3,000
shares of the Company's common stock on the date of election and on the next
four
 
                                      108
<PAGE>
 
anniversaries if re-elected. Each such director elected before 1997 received
an option to purchase a total of 15,000 shares of the Company's common stock
on the date of his or her election. All options under the Directors Plan are
granted at the fair market value of the stock at the time of grant and are for
a term of 10 years from the date of grant. Options granted in 1997 or
thereafter become exercisable after one year following the grant date. Options
granted prior to 1997 become exercisable with respect to 20% of the total
number of shares subject to the option six months after the date of grant and
with respect to an additional 20% at the end of each 12-month period
thereafter on a cumulative basis during the succeeding four years.
 
  Under the Directors Plan, in the event that the Company's shares of common
stock are changed by a stock dividend, split or combination of shares, or a
merger, consolidation or reorganization with another company in which holders
of the Company's common stock receive other securities, or any other relevant
change in the capitalization of the Company, a proportionate or equitable
adjustment will be made in the number or kind of shares subject to unexercised
options or available for options and in the purchase price for shares. If an
option expires or is terminated or cancelled unexercised as to any shares,
such released shares may again be optioned (including a grant in substitution
for a cancelled option). Shares subject to options may be made available from
unissued or reacquired shares of common stock.
 
  Options are not transferable by the optionee otherwise than by will or the
laws of descent and distribution, provided that the Board of Directors may
grant options that are transferable, without payment of consideration, to
immediate family members of the optionee or to trusts or partnerships for such
family members or to charitable organizations (each an "Option Transferee"),
subject to the Company's procedures for administration, and may amend
outstanding options to provide for such transferability. Options terminate if
the optionee ceases to be a director of the Company for any reason other than
death, permanent disability, resignation or retirement. If the optionee ceases
to be a director because of death or permanent disability, the optionee or the
optionee's heirs, legatees, legal representative or the Option Transferee may
exercise the option in full at any time during its term within three months
after the date of termination. In the event of resignation or retirement, an
option may be exercised by the optionee (or if the optionee dies within three
months after such termination, by the optionee's heirs, legatees or legal
representative) or the Option Transferee at any time during its specified term
prior to three months after the date of such resignation or retirement, but
only to the extent it was exercisable at the date of such resignation or
retirement.
 
  Prior to January 1, 1992, upon election to the Board of Directors non-
employee directors received options for 10,000 shares under the Company's 1981
Stock Option Plan for Non-Employee Directors (the "1981 Plan"), the terms of
which are substantially similar to the Directors Plan. No person who is the
holder of an option granted under the 1981 Plan or the Employee Plans or who
has purchased shares upon the exercise of such an option is eligible for a
grant of options under the Directors Plan.
 
DIRECTORS' CHARITABLE ENDOWMENT PROGRAM
 
  The Company maintains a Directors' Charitable Endowment Program pursuant to
which the Company has purchased life insurance policies on members of the
Board of Directors. Under the program, death benefits will be paid to the
Company, and the Company in turn will donate such death benefits (up to
$100,000 for each year of service on the Company's Board of Directors, subject
to a $1,000,000 limit) to one or more charitable organizations recommended by
the director. Directors derive no financial benefit from this program because
all charitable deductions accrue solely to the Company.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The Compensation and Stock Option Committee of the Company's Board of
Directors consisted during 1997 of Messrs. Pedersen (Chairman), Arnelle,
Edwards, Montrone and Peterson and Dr. Cafferty. There are no interlocks
requiring disclosure or insider members of this committee.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS
 
  The Company does not know of any person who, as of February 1, 1998,
directly owned more than five percent of the Company's outstanding common
stock. The Company, however, received a copy of a Schedule 13D filed by a
group consisting of George Soros, Soros Fund Management LLC, Quantum
Industrial Partners LDC, QIH Management Investor, L.P., QIH Management, Inc.,
Stanley F. Druckenmiller, and Duquesne Capital Management, L.L.C. The Schedule
13D filed by such persons indicate that such persons may be deemed to be a
group within the meaning of Section 13(d)(3) of the Securities Exchange Act of
1934, as amended. The Company also received a Schedule 13G for the year ended
December 31, 1997 from Barrow, Hanley, Mewhinney & Strauss, Inc. ("BHMS").
Pursuant to the aggregation and attribution rules relating to the beneficial
ownership of securities promulgated under the Securities Exchange Act of 1934,
as amended, BHMS is deemed to be the beneficial owner of such shares shown
because BHMS is an investment management company which exercises discretionary
investment management over accounts holding such shares. No managed account
alone owns five percent or more of the Company's common stock. The information
presented in the following table is taken from the above-referenced Schedules
13D and 13G:

MEETINGS AND COMMITTEES OF THE BOARD
 
  The Board of Directors has designated several committees of the Board,
including a Compensation and Stock Option Committee, an Audit Committee and a
Nominating and Governance Committee. The Board of Directors held an aggregate
of 17 regular and special meetings in 1997.
 
  The Compensation and Stock Option Committee is responsible for making
recommendations to the Board of Directors regarding salaries and incentive
awards to be paid to executive officers of the Company, and for the
administration of and the grant of equity-based incentives under the Company's
1997 Equity Incentive Plan (the "1997 Company Plan"), and the administration
of the Company's 1982 Stock Option Plan, as amended (the "1982 Company Plan")
and 1992 Stock Option Plan (the "1992 Company Plan" and together with the 1982
Company Plan and the 1997 Company Plan, the "Employee Plans"). The Audit
Committee's functions include making recommendations to the Board of Directors
on the selection of the Company's independent auditors, reviewing the
arrangements for and scope of the independent auditors' examination, reviewing
the results of the annual audit, meeting with the independent auditors, the
Board of Directors and certain officers of the Company
 
                                      115
<PAGE>
 
to review the adequacy of internal controls and reporting, reviewing
compliance with the Company's policies on business ethics and environmental,
health and safety compliance and performing any other duties or functions
deemed appropriate by the Board. The Nominating and Governance Committee's
principal function is to identify and propose to the full Board qualified
nominees to fill vacancies on the Board as they occur, and to review and
report to the Board on director compensation, monitor and make recommendations
to the Board as to corporate governance matters and review and make
recommendations to the Board concerning the organization and functioning of
the Board and its committees.
 
  The Compensation and Stock Option Committee currently consists of Messrs.
Pedersen (Chairman), Arnelle, Edwards, Montrone, Peterson and Dr. Cafferty;
the Audit Committee currently consists of Messrs. Hills (Chairman), Pope and
Rothmeier; and the Nominating and Governance Committee currently consists of
Messrs. Trowbridge (Chairman), Arnelle, Miller and Montrone.
 
  During 1997, the Compensation and Stock Option Committee met eleven times,
the Audit Committee met eight times and the Nominating and Governance
Committee met five times. In 1997, during the time each director served in
such capacity, nine directors attended 100% of the aggregate of the regular
and special meetings of the Board of Directors and applicable committee
meetings, six other directors attended at least 85% of the aggregate of all
meetings of the Board of Directors and applicable committee meetings, and Dr.
Edwards attended 70% of the aggregate of all meetings of the Board of
Directors and applicable committee meetings.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.
 
  When an option is exercised by an optionee under the Employee Plans or WTI's
stock option plans at a time when the fair market value of the underlying
stock exceeds the option exercise price, the difference is treated as ordinary
income to the optionee for income tax purposes and the company which issued
the options is entitled to a deduction equal to such amount. To facilitate an
optionee's purchase of stock upon exercise of such options, the Company and
WTI each had a policy prior to April 1998 of making available interest-free
loans, in an amount up to the equivalent of all applicable tax withholding
requirements, to optionees whose exercise of options results in ordinary
income to them in excess of $10,000. All such loans normally are required to
be repaid not later than April 15 in the year following the year in which such
loans were made, unless otherwise extended. There were no such loans from the
Company and WTI in excess of $60,000 made pursuant to such policy in 1997.
 
  The Company and WTI also each makes available to optionees interest-free
loans for a period not to exceed 15 days to facilitate the exercise of options
and the sale of the underlying stock. The largest aggregate amounts of such
loans from the Company and WTI in excess of $60,000 which were outstanding to
the directors and executive officers of the Company since January 1, 1997 were
as follows: Mr. Koenig--$1,416,800. Such loan was repaid within the 15-day
period. The Company also extended Mr. Getz a loan in the amount of $2,136,744
to facilitate the exercise of WTI options during an 18-day period in which he
was precluded by Company policy from selling the underlying shares. Such loan
was repaid at the end of such period and did not remain outstanding at March
15, 1998. Mr. Getz was indemnified by the Company against approximately $5,800
of interest on such loan and the income tax consequences of such
indemnification.
 
  In connection with his transfer in 1995 from CWM, where he was President, to
the Company, the Company entered into an employment agreement with D. P. Payne
under which Mr. Payne will be paid a minimum annual salary of $400,000. Mr.
Payne also is eligible to receive annual bonuses and all benefits generally
available to executives of the Company. The term of Mr. Payne's employment
under the agreement continues through December 31, 1999. Upon the death or
permanent disability of Mr. Payne, the Company will pay his then current
salary (including bonuses accrued as of the date of termination) for the
balance of the calendar year in which such death or disability occurs but in
no event for less than 180 days. If the Company terminates Mr. Payne's
employment, it will continue to pay him an amount equal to his base salary
until the end of the term of the agreement plus any unpaid but fully accrued
annual bonus for the prior calendar year payable under the Annual Plan, unless
the termination was for cause, in which case its obligations under the
agreement cease. During the term of the agreement and for two years after the
termination of the agreement, Mr. Payne has agreed not to compete with the
Company or its subsidiaries. In March 1997, the Compensation Committee
approved granting to Mr. Payne 34,500 restricted shares of common stock under
the Company's 1997 Equity Incentive Plan (the "1997 Equity Plan"). In June
1997, Mr. Payne's employment agreement was amended to provide that in the
event he should be terminated without cause during the term of the agreement
or at any time thereafter, he would be provided with a minimum of ten years'
service credit under the SERP. In February 1998, Mr. Payne entered into a new
employment security agreement with the Company which superseded his prior
agreement and which contains terms that are substantially similar to the
agreements discussed below that were extended to certain other senior officers
in March 1997. The terms of Mr. Payne's March 1997 restricted stock award
agreement are also substantially similar to those awarded to such other
officers at such time (see discussion below).
 
  In June 1996, in connection with his election as the Company's Chief
Executive Officer, the Company entered into an amended and restated employment
agreement with Phillip B. Rooney. The agreement replaced an agreement
originally entered into between the Company and Mr. Rooney in 1986. Under the
agreement Mr. Rooney would be paid a minimum annual salary of $1,250,000 as
President and Chief Executive Officer of the Company. Mr. Rooney also was
eligible to receive annual bonuses and all benefits generally available to
executives of the Company. The Company also agreed to provide Mr. Rooney with
a split-dollar life insurance arrangement with a death benefit of
approximately $10 million. The term of Mr. Rooney's employment under the
agreement was to continue through June 6, 2001 and would have been
automatically extended on each anniversary date for a period of five years
from such anniversary date unless either party gave written notice of
termination prior to the anniversary date. Upon the death or permanent
disability of Mr. Rooney, the Company
 
                                      117
<PAGE>
 
would have paid annually $2,500,000 for the balance of the term of the
agreement. If the Company breached or terminated the agreement or reduced the
nature and scope of Mr. Rooney's authority and duties, it would have continued
to pay him for five years unless the termination was for cause, in which case
its obligations under the agreement would have ceased. In the event of a
change in control of the Company, Mr. Rooney was entitled to elect to
terminate the agreement and receive a lump sum payment of three times his
average annual compensation (including bonuses) over the immediately preceding
five years, which amount would be increased should an excise tax be imposed on
him because of the payment. Were a change in control of the Company to have
occurred on December 31, 1997 and if Mr. Rooney's employment with the Company
were terminated as provided in the employment agreement, it is estimated that
Mr. Rooney would have been eligible to receive approximately $5,457,620
(assuming no increase for any excise tax). During the term of the agreement
and for a period of three years thereafter, Mr. Rooney agreed not to compete
with the Company or its subsidiaries. In connection with Mr. Rooney's
resignation as President and Chief Executive Officer on February 17, 1997, the
Company gave notice of its decision to terminate such agreement. As a result
of such notice, the agreement will terminate on February 17, 2002, unless
earlier terminated pursuant to the agreement. During 1997, Mr. Rooney began to
receive cash compensation under the agreement at an annual rate of $2,500,000
in lieu of all salary, bonuses, incentive or other performance-based
compensation and the Compensation Committee accelerated the vesting of all
unvested stock options held by Mr. Rooney.
 
  In August 1996, the Company entered into employment agreements with James E.
Koenig, former Executive Vice President of the Company, and Herbert A. Getz,
Senior Vice President and General Counsel of the Company (the "Executives").
The agreements provide that Mr. Koenig would be paid a minimum annual salary
of $600,000 and Mr. Getz would be paid a minimum annual salary of $450,000.
Each of the Executives also would be eligible to receive annual bonuses and
all benefits generally available to executives of the Company. The term of the
Executive's employment under each of the agreements continues until August 14,
1999 and is automatically extended on each anniversary date for a period of
three years from such anniversary date unless the Company gives notice of
termination, in which case the term is automatically extended and expires
three years from the date of such notice. Upon the death or permanent
disability of the Executive, the Company will pay annually the Executive's
then current base salary for thirty-six months. If the Company terminates the
agreement or reduces the nature and scope of the Executive's duties or
relocates the primary employment location of the Executive, it will continue
to pay him his then current base salary and his prorated annual bonus and long
term bonus for three years unless the termination was for cause, in which case
its obligations under the agreement cease. In the event of a change of control
of the Company, the Executive may elect to terminate the agreement and receive
a lump sum payment of three times his average annual compensation (including
bonuses) over the immediately preceding five years, which amount will be
increased should an excise tax be imposed on him because of the payment. Were
a change in control to have occurred on December 31, 1997 and if each
Executive's employment with the Company were terminated as provided in the
employment agreements, it is estimated that Messrs. Koenig and Getz would have
been eligible to receive approximately $2,113,081 and $1,479,101, respectively
(assuming no increase for any excise tax). During the term of the agreements,
and for a period of one year thereafter, each Executive has agreed not to
compete with the Company or its subsidiaries. Concurrently with the execution
of the employment agreements, the Company granted to Mr. Koenig 45,000 shares
of its common stock and to Mr. Getz 35,000 shares of its common stock, subject
in each case to a restricted stock agreement. Under the terms of the
restricted stock agreements, the Executive cannot sell, assign, pledge or
otherwise transfer such shares until the expiration of the period of the
covenant not to compete contained in the employment agreement or his death or
permanent disability. Except as provided below, if the Executive voluntarily
terminates his employment prior to the tenth anniversary of the grant of such
shares, all shares shall be forfeited. If such termination occurs after such
tenth anniversary, such shares shall be vested, but remain subject to such
restrictions. Vesting accelerates upon termination by the Company of the
Executive's employment other than for cause, upon his retirement on or after
reaching age 60, if the Company reduces the nature or scope of his authority
and duties or his compensation or changes the location of his employment, or
upon his death or permanent disability. Dividends upon such shares are deemed
to be reinvested in additional shares and subject to the same restrictions. In
connection with Mr. Koenig's resignation as Executive Vice President on
October 31, 1997, the Company gave notice of its decision to terminate Mr.
Koenig's employment
 
                                      118
<PAGE>
 
agreement. As a result of such notice, the agreement will terminate on October
31, 2000, unless earlier terminated pursuant to the agreement. During 1997,
Mr. Koenig began to receive cash compensation at an annual rate of $600,000.
 
  On March 10, 1998, the Company's Board of Directors approved an amendment to
Mr. Getz's employment agreement to fix the amounts payable thereunder in the
event the Company terminates Mr. Getz's employment without cause or he is
constructively discharged at $900,000 per year. This amount represents his
current base salary plus his target annual and long-term incentive levels. In
consideration thereof, the Company obtained a commitment from Mr. Getz to
remain with the Company through the Merger with USA Waste and for a reasonable
transition time thereafter, which will be until at least June 30, 1999 unless
terminated earlier by the Company.
 
  In March 1997, the Company's Board of Directors approved an employment
security agreement with John D. Sanford, the Company's Senior Vice President
and Chief Financial Officer. Mr. Sanford voluntarily resigned on October 29,
1997. The term of the agreement was to continue until March 11, 1999, and was
to be automatically extended on each anniversary date for a period of two
years from such anniversary date unless a party were to give 30 days' prior
written notice of termination. If the Company were to have terminated Mr.
Sanford's employment, or reduced the nature and scope of Mr. Sanford's duties
or relocated his primary employment location, it would have continued to pay
him his then current base salary for two years and his prorated annual bonus
for the year of such termination, reduction or relocation, unless the
termination was for cause, in which case its obligations under the agreement
would cease. In addition, the Company was required to request the Compensation
Committee to accelerate all of Mr. Sanford's unvested stock options. During
the term of the agreement and for a period of one year thereafter, Mr. Sanford
agreed not to compete with the Company or its subsidiaries. The Compensation
Committee also granted to Mr. Sanford 28,800 restricted shares of its common
stock under the 1997 Equity Plan. Upon Mr. Sanford's voluntary termination of
his employment, all shares were forfeited.
 
  In March 1997, the Company's Board of Directors approved employment security
agreements with Jerry W. Caudle, James E. O'Connor, Michael J. Cole and L.
Michael Collier, each a Senior Vice President of the Company, and Donald R.
Chappel, Vice President and Acting Chief Financial Officer of the Company, the
terms of which are substantially similar to Mr. Sanford's employment security
agreement. The Compensation Committee also granted shares of restricted common
stock under the Company's 1997 Equity Plan to such officers in the following
amounts: Mr. Caudle--23,900; Mr. O'Connor--23,600; Mr. Cole--23,200; Mr.
Collier--23,900; and Mr. Chappel--17,700. Under the terms of the restricted
stock award agreement entered into in connection with this grant, and except
as provided below, the officer will not be able to sell, assign, pledge or
otherwise transfer such shares prior to ten years from the date of the grant.
If the officer voluntarily terminates his employment before the tenth
anniversary of the date of the grant, or if he should be terminated by the
Company for cause, all shares will be forfeited. Vesting of all such shares
will accelerate upon a change in control of the Company, the officer's
retirement after age 62, or his death or disability. If the officer's
employment is terminated without cause, the vesting of such shares will be
accelerated at 2.5% of the grant for every three months of completed service
after the date of the grant. Release of vested shares will occur upon
satisfaction of the obligation not to compete under the officer's employment
security agreement. Dividends upon such shares will be deemed to be reinvested
in additional shares and subject to the same restrictions. The Company also
entered into a similar agreement with Mark T. Spears, Vice President and
Controller of the Company, in July 1997, but without making a grant of
restricted shares.
 
  In June 1997, the Company's Board of Directors approved an employment
security agreement with Joseph M. Holsten, the Company's Executive Vice
President and Chief Operating Officer. The term of the agreement continues
until June 20, 2000, provided that unless a party gives 30 days' prior written
notice on June 20, 1998 and on each successive June 20, the term of the
agreement shall be renewed for a period ending on the earlier of the date
three years from such June 20 or the date of his sixty-second birthday unless
earlier terminated pursuant to the terms of the agreement. The agreement
provides for Mr. Holsten's salary to be increased to $650,000 as of June 20,
1997, and for him to be paid a cash bonus of $300,000 for 1997. If the Company
terminates Mr. Holsten's employment, or reduces the nature and scope of Mr.
Holsten's duties or relocates his primary employment location, it will
continue to pay him his then current base salary for three years and his
prorated
 
                                      119
<PAGE>
 
annual and long term incentive plan compensation with respect to any
participation rights in the Company's annual or long term incentive plans
which have been awarded prior to the date of the notice of termination, unless
the termination was for cause, in which case all of the Company's obligations
under the agreement will cease. In addition, under such circumstances the
Company will request the Compensation Committee to accelerate all of Mr.
Holsten's unvested stock options. During the term of the agreement and for a
period of one year thereafter or during the three-year period after
termination, if longer, Mr. Holsten has agreed not to compete with the Company
or its subsidiaries. The Compensation Committee also granted to Mr. Holsten
55,000 shares of restricted common stock under the 1997 Equity Plan. The terms
of Mr. Holsten's restricted stock award agreement are substantially similar to
those extended to certain other senior officers in March 1997. The
Compensation Committee also approved granting to Mr. Holsten options to
acquire 100,000 shares of the Company's common stock under the 1997 Equity
Plan. In connection with the agreement, the Company has agreed to loan Mr.
Holsten $1,000,000 to purchase shares of the Company's common stock at an
annual rate equal to the three month London Interbank Offered Rate for the
first London business day of each quarter that the loan is outstanding.
 
  In June 1997, the Company entered into a Supplemental Retirement Benefit
Agreement with Thomas C. Hau, then the Company's Vice President, Controller
and Principal Accounting Officer, which provides that, if Mr. Hau remains
employed by the Company until at least April 1, 1998, or such earlier date as
his employment is terminated as a result of death, disability or involuntary
termination other than for cause, the monthly SERP benefit payable to Mr. Hau
shall be equal to three percent of Mr. Hau's Final Average Compensation per
year of service, and that Mr. Hau's benefits under the Company's Non-Qualified
Profit Sharing and Savings Plus Plan will be vested.
 
  Effective July 13, 1997, the Company entered into an employment agreement
with Ronald T. LeMay, in connection with his election as Chairman of the
Board, President and Chief Executive Officer of the Company. Mr. LeMay
voluntarily resigned on October 29, 1997. The term of Mr. LeMay's employment
under the agreement was to continue until July 13, 2002, and was to be
automatically extended for additional one-year periods after such date unless
either party were to give at least 12 months prior written notice electing not
to extend the term of employment. The employment agreement provided that Mr.
LeMay would be paid an annual base salary of $1,500,000, subject to increase
in the discretion of the Board of Directors, and would participate in the
Company's Corporate Incentive Bonus Plan with a target bonus opportunity equal
to 80% of his base salary and with his 1997 incentive award to be not less
than $1 million. The agreement also provided that Mr. LeMay would participate
in the LTIP, with guaranteed minimum payouts of $350,000 and $250,000 for the
performance periods ending in 1998 and 1999, respectively. The agreement
further provided that Mr. LeMay would be awarded options to acquire 500,000
shares of the Company's common stock in each of four years beginning in April
1998 at an exercise price not less than the closing sale price of the common
stock on the date of grant. Each such future option grant would have vested
nine and one-half years after the date of grant, provided that if the price of
a share of the Company's common stock were at least 1.6105 times the exercise
price for at least 30 trading days within a consecutive period of 45 trading
days between the fourth and fifth anniversaries of the date of grant, that
grant would become exercisable on the fifth anniversary of the date of the
grant.
 
  Pursuant to the employment agreement, Mr. LeMay was granted under the 1997
Equity Plan (a) 353,000 restricted shares of the Company's common stock with
terms substantially similar to those of Mr. Caudle's restricted stock award
described above, except that the restrictions were to lapse with respect to
20% of the restricted shares on each of the first five anniversaries of the
award date, and (b) options to purchase a total of two million shares of the
Company's common stock at an exercise price of $33.10 per share. Under the
employment agreement, Mr. LeMay was also granted stock appreciation rights
with respect to 500,000 shares of Sprint Corporation common stock at an
exercise price of $47.9375 per share, which were to become exercisable on June
9, 2002 and expire on June 8, 2007. Mr. LeMay was granted stock appreciation
rights with respect to an additional 500,000 shares of Sprint Corporation
common stock at the same exercise price, which were to become exercisable on
the fifth anniversary of the grant date only if the fair market value of
Sprint Corporation common stock were at least $95.875 per share on any 30
trading days within a consecutive period of 45 trading days between the fourth
and fifth anniversaries of the grant date, or alternatively, if such condition
were not met, on
 
                                      120
<PAGE>
 
the last day of such a 45-day period between the fourth and sixth
anniversaries of the grant date but only if the fair market value of Sprint
Corporation common stock were at least $95.875 on any 30 trading days during
such period. Under the employment agreement, Mr. LeMay also received credit
for 12 years of benefit and eligibility service under the SERP upon
commencement of employment (with his SERP benefits to vest at the rate of 20%
on each of the first five anniversaries of the effective date of the
employment agreement and to be offset by any other pension benefit he may have
received from the Company or Sprint Corporation), and was also entitled to a
survivor benefit in the form of 10 annual payments each equal to 25% of his
highest annual salary during the five-year period immediately preceding his
death if he were to die before retirement (or if he were to die after retiring
or becoming permanently disabled, a benefit equal to 300% of his highest
annual salary during the five-year period immediately prior to the time of his
retirement or disability, payable either in a lump sum or in installments). At
least 13 months before retirement, Mr. LeMay was permitted to elect a
supplemental retirement benefit in lieu of all or a portion of such survivor
benefit.
 
  In the event Mr. LeMay's employment were terminated due to his death, the
Company would have been required to pay his base salary through the end of the
month in which the death occured, he would have received pro rata payouts of
any annual incentive and LTIP awards, his outstanding stock options would have
been exercisable until the earlier of the first anniversary of the date of
death or the tenth anniversary of the date of grant, the restrictions on his
restricted stock would have lapsed, and the Sprint Corporation stock
appreciation rights would have been exercisable in accordance with their
terms. In the event of his termination due to disability, Mr. LeMay would have
been entitled to receive substantially the same benefits. In the event Mr.
LeMay's employment were terminated without cause or constructively terminated
without cause, the Company would have been obligated to pay his base incentive
and LTIP awards plus an annual incentive award based on his target bonus
opportunity for 24 months following the date of termination, his outstanding
stock options would have been exercisable until the earlier of the third
anniversary of the date of termination or the tenth anniversary of the date of
grant, the restrictions on his restricted stock would have lapsed, and the
Sprint Corporation stock appreciation rights would have been exercisable in
accordance with their terms. In the event of termination without cause or
constructive termination without cause after a change in control of the
Company, Mr. LeMay would have received the same benefits, except that in lieu
of the salary and annual incentive benefits described above, Mr. LeMay would
have received his base salary and annual incentive awards for 36 months
following termination, which amount would have been increased should an excise
tax be imposed on him because of the payments. During the term of his
employment and for a period of three years thereafter, Mr. LeMay agreed not to
compete with the Company or its subsidiaries. As a result of his voluntary
resignation on October 29, 1997, Mr. LeMay forfeited all benefits under his
employment agreement other than salary through the date of resignation.
 
  Effective October 29, 1997, the Company entered into an employment agreement
with Robert S. Miller, Acting Chairman of the Board and Chief Executive
Officer of the Company. The term of Mr. Miller's employment under the
agreement continues until the earlier of (a) approval by the Board of
Directors of the Company of the hiring of a successor as Chairman of the Board
and Chief Executive Officer, (b) Mr. Miller's death or disability, or (c)
termination of his service upon written notice given either by Mr. Miller or
the Board at least seven days prior to the effective date of such termination.
The agreement provides that Mr. Miller will be paid a salary at the annual
rate of $600,000 for so long as he serves as Acting Chairman of the Board and
Chief Executive Officer. Pursuant to the agreement, Mr. Miller was granted an
option under the 1997 Company Plan to purchase 75,000 shares of common stock
at an exercise price of $23.375, exercisable upon the earlier of (a) the
Board's approval of the hiring of Mr. Miller's successor as Chairman of the
Board and Chief Executive Officer, (b) Mr. Miller's death or disability, or
(c) the termination of Mr. Miller's employment by the Board. Upon becoming
exercisable, the option will remain exercisable through the earlier of
November 3, 2007 or the ninetieth day after Mr. Miller ceases to serve as a
member of the Board. The salary and option described above were Mr. Miller's
exclusive compensation for his service as Acting Chairman of the Board and
Chief Executive Officer of the Company. On March 10, 1998, the Board appointed
Robert S. Miller as Chief Executive Officer, approved an increase in his
annual salary to $900,000, named him as a participant in the Annual Plan and
established his 1998 annual incentive target level at 80% of his salary, and
granted him an option for 235,000
 
                                      121
<PAGE>
 
shares of the Company's common stock at an exercise price of $24.3875 on the
same terms as his November 4, 1997 stock option grant. The options expire ten
years after their grant or, if earlier, 90 days following Mr. Miller's
retirement from the Board.
 
  On February 5, 1998, the Company sold an aircraft with a net book value of
$11,491,835 to Dean L. Buntrock, former Chairman of the Board and Chief
Executive Officer of the Company, for $14,058,886 in cash. The price was
determined after the Company obtained four independent appraisals ranging from
$13,772,998 to $14,500,000, with an average of $14,165,124, which was then
reduced by half of the estimated amount of an avoided broker's commission. The
Company also entered into an agreement pursuant to which the Company may lease
the aircraft on a non-exclusive basis. The lease has a one year term, subject
to termination by either party at any time upon thirty days' notice. The
Company also entered into a sublease of hangar space for the aircraft for a
term of one year, renewing annually thereafter, pursuant to which the Company
will recoup approximately 25% of the Company's charges for rent, taxes,
utilities, common area maintenance and other support costs at the Company's
hangar. The Company also entered into a management services agreement pursuant
to which the Company will provide flight crews, maintenance, recordkeeping and
scheduling services for the aircraft. The Company is to be paid a management
fee of $60,000 per year, two pilots' salaries and benefits, one mechanic's
salary and benefits, and 100% of the necessary recurring training costs for
two pilots and one mechanic. In addition, Mr. Buntrock will pay separately all
direct expenses connected with the operation and maintenance of the aircraft.
The Management Services Agreement will have a term of one year. If this
agreement is terminated, the hangar sublease will terminate as well. The terms
of these agreements with Mr. Buntrock were reviewed and approved by the Audit
Committee and the Board of Directors as being fair to the Company and in its
best interests.
 
  On March 10, 1998, the Board approved an employment security agreement with
Paul G. George as the Company's new Senior Vice President--Human Resources.
The term of the agreement continues until March 10, 1999 and automatically
extends on each March 10 for a period of two years from such anniversary date
unless a party were to give 30 days' prior written notice of termination. If
the Company were to terminate Mr. George's employment, or reduce his salary,
benefits or the nature and scope of Mr. George's duties or relocate his
primary employment location, it would continue to pay him his then current
base salary for two years, his prorated annual bonus for the year of such
termination, reduction or relocation and all of Mr. George's unvested stock
options will automatically accelerate, unless the termination was for cause,
in which case its obligations under the agreement would cease. The agreement
also gives Mr. George protection in the form of a tax gross-up payment in the
event an excise tax under Internal Revenue Code Section 4999 is triggered as a
result of the payments under the agreement. During the term of the agreement
and for a period of one year thereafter, Mr. George has agreed not to compete
with the Company or its subsidiaries.

               which funds are to be disbursed, which shall comply with the
               requirements of Section 2.04.

If no election as to the Type of Borrowing is specified, then the requested
Borrowing shall be an ABR Borrowing. If no Interest Period is specified with
respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed
to have selected an Interest Period of one month's duration. Promptly following
receipt of a Borrowing Request in accordance with this Section, the
Administrative Agent shall advise each Lender of the details thereof and of the
amount of such Lender's Loan to be made as part of the requested Borrowing.

          SECTION 2.04.  Funding of Borrowings.  (a)  Each Lender shall make
each Loan to be made by it hereunder on the proposed date thereof by wire
transfer of immediately available funds by 1:00 p.m., New York City time, to the
account of the Administrative Agent most recently designated by it for such
purpose by notice to the Lenders.  The Administrative Agent will make such Loans
available to the Borrower by promptly crediting the amounts so received (on the
date of receipt so long as the 1:00 p.m. deadline specified above is satisfied),
in like funds, to an account of the Borrower maintained with the Administrative
Agent in New York City and designated by the Borrower in the applicable
Borrowing Request.

          (b)  Unless the Administrative Agent shall have received notice from a
Lender prior to the proposed date of any Borrowing that such Lender will not
make available to the Administrative Agent such Lender's share of such
Borrowing, the Administrative Agent may assume that such Lender has made such
share available on such date in accordance with paragraph (a) of this Section
and may, in reliance upon such assumption, make available to the Borrower a
corresponding amount.  In such event, if a Lender has not in fact made its share
of the applicable Borrowing available to the Administrative Agent, then the
applicable Lender and the Borrower severally agree to pay to the Administrative
Agent forthwith on demand such corresponding amount with interest thereon, for
each day from and including the date such amount is made available to the
Borrower to but excluding the date of payment to the Administrative Agent, at
(i) in the case of such Lender, the Federal Funds Effective Rate or (ii) in the
case of the Borrower, the interest rate applicable to ABR Loans.  If such Lender
pays such amount to the Administrative Agent, then such amount shall constitute
such Lender's Loan included in such Borrowing.

          SECTION 2.05.  Interest Elections.  (a)  Each Borrowing initially
shall be of the Type specified in the applicable Borrowing Request and, in the
case of a Eurodollar Borrowing, shall have an initial Interest Period as
specified in such Borrowing Request.  Thereafter, the Borrower may elect to
convert such Borrowing to a different Type or to continue such Borrowing and, in
the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as
provided in this Section.  The Borrower may elect different options with respect
to different portions of the affected Borrowing, in which case each such portion
shall be allocated ratably among the Lenders holding the Loans comprising such
Borrowing, and the Loans comprising each such portion shall be considered a
separate Borrowing.

          (b)  To make an election pursuant to this Section, the Borrower shall
notify the Administrative Agent of such election by telephone by the time that a
Borrowing Request would be required under Section 2.03 if the Borrower were
requesting a Borrowing of the Type resulting from such election to be made on
the effective date of such election.  Each such telephonic Interest

                                                                              14

Election Request shall be irrevocable and shall be confirmed promptly by hand
delivery or telecopy to the Administrative Agent of a written Interest Election
Request in a form approved by the Administrative Agent and signed by the
Borrower.

          (c)  Each telephonic and written Interest Election Request shall
specify the following information in compliance with Section 2.02:

               (i) the Borrowing to which such Interest Election Request applies
     and, if different options are being elected with respect to different
     portions thereof, the portions thereof to be allocated to each resulting
     Borrowing (in which case the information to be specified pursuant to
     clauses (iii) and (iv) below shall be specified for each resulting
     Borrowing);

               (ii) the effective date of the election made pursuant to such
     Interest Election Request, which shall be a Business Day;

               (iii) whether the resulting Borrowing is to be an ABR Borrowing
     or a Eurodollar Borrowing; and

               (iv) if the resulting Borrowing is a Eurodollar Borrowing, the
     Interest Period to be applicable thereto after giving effect to such
     election, which shall be a period contemplated by the definition of the
     term "Interest Period".

If any such Interest Election Request requests a Eurodollar Borrowing but does
not specify an Interest Period, then the Borrower shall be deemed to have
selected an Interest Period of one month's duration.

          (d)  Promptly following receipt of an Interest Election Request, the
Administrative Agent shall advise each Lender of the details thereof and of such
Lender's portion of each resulting Borrowing.

          (e)  If the Borrower fails to deliver a timely Interest Election
Request with respect to a Eurodollar Borrowing prior to the end of the Interest
Period applicable thereto, then, unless such Borrowing is repaid as provided
herein, at the end of such Interest Period such Borrowing shall be converted to
an ABR Borrowing.  Notwithstanding any contrary provision hereof, if an Event of
Default has occurred and is continuing and the Administrative Agent, at the
request of the Required Lenders, so notifies the Borrower, then, so long as an
Event of Default is continuing (i) no outstanding Borrowing may be converted to
or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar
Borrowing shall be converted to an ABR Borrowing at the end of the Interest
Period applicable thereto.

          SECTION 2.06.  Termination and Reduction of Commitments.  (a) Unless
previously terminated, the Commitments shall terminate on the Maturity Date.

          (b)  The Borrower may at any time terminate, or from time to time
reduce, the Commitments; provided that (i) each reduction of the Commitments
shall be in an amount that is an integral multiple of $1,000,000 and not less
than $10,000,000 and (ii) the Borrower shall not terminate or reduce the
Commitments if, after giving effect to any concurrent prepayment of the Loans in
accordance with Section 2.08, the aggregate outstanding principal amount of the
Loans would exceed the total Commitments.

                                                                              15

          (c)  The Borrower shall notify the Administrative Agent of any
election to terminate or reduce the Commitments under paragraph (b) of this
Section at least three Business Days prior to the effective date of such
termination or reduction, specifying such election and the effective date
thereof.  Promptly following receipt of any notice, the Administrative Agent
shall advise the Lenders of the contents thereof.  Each notice delivered by the
Borrower pursuant to this Section shall be irrevocable; provided that a notice
of termination of the Commitments delivered by the Borrower may state that such
notice is conditioned upon the effectiveness of other credit facilities, in
which case such notice may be revoked by the Borrower (by notice to the
Administrative Agent on or prior to the specified effective date) if such
condition is not satisfied.

          (d)  Any termination or reduction of the Commitments shall be
permanent.  Each reduction of the Commitments shall be made ratably among the
Lenders in accordance with their respective Commitments.

          SECTION 2.07.  Repayment of Loans; Evidence of Debt.  (a)  The
Borrower hereby unconditionally promises to pay to the Administrative Agent for
the account of each Lender the then unpaid principal amount of each Loan on the
Maturity Date.

          (b)  Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing the indebtedness of the Borrower to such
Lender resulting from each Loan made by such Lender, including the amounts of
principal and interest payable and paid to such Lender from time to time
hereunder.

          (c)  The Administrative Agent shall maintain accounts in which it
shall record (i) the amount of each Loan made hereunder, the Type thereof and
the Interest Period applicable thereto, (ii) the amount of any principal or
interest due and payable or to become due and payable from the Borrower to each
Lender hereunder and (iii) the amount of any sum received by the Administrative
Agent hereunder for the account of the Lenders and each Lender's share thereof.

          (d)  The entries made in the accounts maintained pursuant to paragraph
(b) or (c) of this Section shall be prima facie evidence of the existence and
amounts of the obligations recorded therein; provided that the failure of any
Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligation of the Borrower to repay
the Loans in accordance with the terms of this Agreement.

          (e)  Any Lender may request that Loans made by it be evidenced by a
promissory note.  In such event, the Borrower shall prepare, execute and deliver
to such Lender a promissory note payable to the order of such Lender (or, if
requested by such Lender, to such Lender and its registered assigns) and in a
form approved by the Administrative Agent.  Thereafter, the Loans evidenced by
such promissory note and interest thereon shall at all times (including after
assignment pursuant to Section 9.04) be represented by one or more promissory
notes in such form payable to the order of the payee named therein (or, if such
promissory note is a registered note, to such payee and its registered assigns).

          SECTION 2.08.  Prepayment of Loans.  (a)  The Borrower shall have the
right at any time and from time to time to prepay any Borrowing in whole or in
part, subject to prior notice in accordance with paragraph (b) of this Section.

          (b)  The Borrower shall notify the Administrative Agent by telephone
(confirmed by telecopy) of any prepayment hereunder (i) in the case of
prepayment of a Eurodollar Borrowing, not later than 11:00 a.m., New York City
time, three Business Days before the date of 
<PAGE>
 
                                                                              16

prepayment or (ii) in the case of prepayment of an ABR Borrowing, not later than
11:00 a.m., New York City time, one Business Day before the date of prepayment.
Each such notice shall be irrevocable and shall specify the prepayment date and
the principal amount of each Borrowing or portion thereof to be prepaid;
provided that, if a notice of prepayment is given in connection with a
conditional notice of termination of the Commitments as contemplated by Section
2.06, then such notice of prepayment may be revoked if such notice of
termination is revoked in accordance with Section 2.06. Promptly following
receipt of any such notice relating to a Borrowing, the Administrative Agent
shall advise the Lenders of the contents thereof. Each partial prepayment of any
Borrowing shall be in an amount that would be permitted in the case of an
advance of a Borrowing of the same Type as provided in Section 2.02. Each
prepayment of a Borrowing shall be applied ratably to the Loans included in the
prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the
extent required by Section 2.10.

          SECTION 2.09.  Commitment Fees.  The Borrower agrees to pay to the
Administrative Agent for the account of each Lender a commitment fee, which
shall accrue at an annual rate of 0.375% on the average daily unutilized amount
of the Commitment of such Lender during the period from and including the
Effective Date to but excluding the date on which such Commitment terminates. 
Accrued commitment fees shall be payable in arrears, based on invoices submitted
by the Administrative Agent to the Borrower, on the last day of March, June,
September and December of each year and on the date on which the Commitments
terminate, commencing on March 31, 1998, and shall be paid in immediately
available funds to the Administrative Agent for distribution to the Lenders. 
Commitment fees shall be computed on the basis of a year of 360 days and shall
be payable for the actual number of days elapsed (including the first day but
excluding the last day).  Commitment fees paid shall not be refundable under any
circumstances.

          SECTION 2.10.  Interest.  (a)  The Loans comprising each ABR Borrowing
shall bear interest at a rate per annum equal to the Alternate Base Rate plus
0.25%.

          (b)  The Loans comprising each Eurodollar Borrowing shall bear
interest at a rate per annum equal to the Adjusted LIBO Rate for the Interest
Period in effect for such Borrowing plus 1.25%.

          (c)  Notwithstanding the foregoing, if any principal of or interest on
any Loan or any fee or other amount payable by the Borrower hereunder is not
paid when due, whether at stated maturity, upon acceleration or otherwise, such
overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the
rate otherwise applicable to such Loan as provided above or (ii) in the case of
any other amount, 2% plus the rate applicable to ABR Loans as provided above.

          (d)  Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan; provided that (i) interest accrued pursuant
to paragraph (c) of this Section shall be payable on demand, (ii) in the event
of any repayment or prepayment of any Loan (other than a prepayment of an ABR
Loan prior to the end of the Availability Period), accrued interest on the
principal amount repaid or prepaid shall be payable on the date of such
repayment or prepayment, (iii) in the event of any conversion of any Eurodollar
Loan prior to the end of the current Interest Period therefor, accrued interest
on such Loan shall be payable on the effective date of such conversion and (iv)
all accrued interest shall be payable upon termination of the Commitments.

                                                                              17

          (e)  All interest hereunder shall be computed on the basis of a year
of 360 days, except that interest computed by reference to the Alternate Base
Rate at times when the Alternate Base Rate is based on the Prime Rate shall be
computed on the basis of a year of 365 days (or 366 days in a leap year), and in
each case shall be payable for the actual number of days elapsed (including the
first day but excluding the last day).  The applicable Alternate Base Rate or
Adjusted LIBO Rate shall be determined by the Administrative Agent, and such
determination shall be conclusive absent manifest error.

          SECTION 2.11.  Alternate Rate of Interest.  If prior to the
commencement of any Interest Period for a Eurodollar Borrowing:

          (a) the Administrative Agent determines (which determination shall be
     conclusive absent manifest error) that adequate and reasonable means do not
     exist for ascertaining the Adjusted LIBO Rate for such Interest Period; or

          (b) the Administrative Agent is advised by the Required Lenders that
     the Adjusted LIBO Rate for such Interest Period will not adequately and
     fairly reflect the cost to such Lenders of making or maintaining their
     Loans included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective
and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such
Borrowing shall be made as an ABR Borrowing.

          SECTION 2.12.  Increased Costs.  (a)  If any Change in Law shall:

          (i) impose, modify or deem applicable any reserve, special deposit or
     similar requirement against assets of, deposits with or for the account of,
     or credit extended by, any Lender (except any such reserve requirement
     reflected in the Adjusted LIBO Rate); or

          (ii) impose on any Lender or the London interbank market any other
     condition affecting this Agreement or Eurodollar Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan (or of maintaining its
obligation to make any such Loan) or to reduce the amount of any sum received or
receivable by such Lender hereunder (whether of principal, interest or
otherwise), then the Borrower will pay to such Lender such additional amount or
amounts as will compensate such Lender for such additional costs incurred or
reduction suffered.

          (b)  If any Lender determines that any Change in Law regarding capital
requirements has or would have the effect of reducing the rate of return on such
Lender's capital or on the capital of such Lender's holding company, if any, as
a consequence of this Agreement or the Loans made by such Lender to a level
below that which such Lender or such Lender's holding company could have
achieved but for such Change in Law (taking into consideration such Lender's
policies and the policies of such Lender's holding company with respect to
capital adequacy), then from time to time the Borrower will pay to such Lender
such additional amount 
<PAGE>
 
                                                                              18

or amounts as will compensate such Lender or such Lender's holding company for
any such reduction suffered.

          (c)  A certificate of a Lender setting forth the amount or amounts
necessary to compensate such Lender or its holding company, as the case may be,
as specified in paragraph (a) or (b) of this Section shall be delivered to the
Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender the amount shown as due on any such certificate within 30 days after
receipt thereof.

          (d)  Failure or delay on the part of any Lender to demand compensation
pursuant to this Section shall not constitute a waiver of such Lender's right to
demand such compensation; provided that the Borrower shall not be required to
compensate a Lender pursuant to this Section for any increased costs or
reductions incurred more than six months prior to the date that such Lender
notifies the Borrower of the Change in Law giving rise to such increased costs
or reductions and of such Lender's intention to claim compensation therefor;
provided, further that, if the Change in Law giving rise to such increased costs
or reductions is retroactive, then the six-month period referred to above shall
be extended to include the period of retroactive effect thereof.

          (e)  Notwithstanding any other provision of this Section 2.12, no
Lender shall demand compensation for any increased cost or reduction or other
amount referred to above if it shall not at the time be the general policy or
practice of such Lender to demand such compensation in similar circumstances
under comparable provisions of other credit agreements.

          SECTION 2.13.  Break Funding Payments.  In the event of (a) the
payment of any principal of any Eurodollar Loan other than on the last day of an
Interest Period applicable thereto (including as a result of an Event of
Default), (b) the conversion of any Eurodollar Loan other than on the last day
of the Interest Period applicable thereto, (c) the failure to borrow, convert,
continue or prepay any Loan on the date specified in any notice delivered
pursuant hereto (regardless of whether such notice is permitted to be revocable
under Section 2.08(b) and is revoked in accordance herewith), or (d) the
assignment of any Eurodollar Loan other than on the last day of the Interest
Period applicable thereto as a result of a request by the Borrower pursuant to
Section 2.16, then, in any such event, the Borrower shall compensate each Lender
for the loss, cost and expense attributable to such event. In the case of a
Eurodollar Loan, the loss to any Lender attributable to any such event shall be
deemed to include an amount determined by such Lender to be equal to the excess,
if any, of (i) the amount of interest that such Lender would pay for a deposit
equal to the principal amount of such Loan for the period from the date of such
payment, conversion, failure or assignment to the last day of the then current
Interest Period for such Loan (or, in the case of a failure to borrow, convert
or continue, the duration of the Interest Period that would have resulted from
such borrowing, conversion or continuation) if the interest rate payable on such
deposit were equal to the Adjusted LIBO Rate for such Interest Period, over (ii)
the amount of interest that such Lender would earn on such principal amount for
such period if such Lender were to invest such principal amount for such period
at the interest rate that would be bid by such Lender (or an affiliate of such
Lender) for dollar deposits from other banks in the eurodollar market at the
commencement of such period. A certificate of any Lender setting forth any
amount or amounts that such Lender is entitled to receive pursuant to this
Section shall be delivered to the Borrower and shall be conclusive absent
manifest error. The Borrower shall pay such Lender the amount shown as due on
any such certificate within 10 days after receipt thereof.

          SECTION 2.14.  Taxes.  (a)  Any and all payments by or an account of
any obligation of the Borrower hereunder shall be made free and clear of and
without deduction for 
<PAGE>
 
                                                                              19

any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be
required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section) the Administrative Agent or the relevant Lender receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower shall make such deductions and (iii) the Borrower shall pay
the full amount deducted to the relevant Governmental Authority in accordance
with applicable law.

          (b)  In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

          (c)  The Borrower shall indemnify the Administrative Agent and each
Lender, within 10 days after written demand therefor, for the full amount of any
Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes
imposed or asserted on or attributable to amounts payable under this Section)
paid by the Administrative Agent or such Lender, as the case may be, and any
penalties, interest and reasonable expenses arising therefrom or with respect
thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority.  A
certificate as to the amount of such payment or liability delivered to the
Borrower by a Lender, or by the Administrative Agent on its own behalf or on
behalf of a Lender, shall be conclusive absent manifest error.

          (d)  As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by the Borrower to a Governmental Authority, the Borrower shall
deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of
the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Administrative Agent.

          (e)  Each Foreign Lender shall deliver to the Borrower and the
Administrative Agent two copies of either U.S. Internal Revenue Service Form
1001 or Form 4224, or, in the case of a Foreign Lender claiming exemption from
U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with
respect to payments of "portfolio interest", a Form W-8, or any subsequent
versions thereof or successors thereto (and, if such Foreign Lender delivers a
Form W-8, an annual certificate representing that such Foreign Lender is not a
"bank" for purposes of Section 881(c) of the Code, is not a 10-percent
shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the
Borrower and is not a controlled foreign corporation related to the Borrower
(within the meaning of Section 864(d)(4) of the Code)), properly completed and
duly executed by such Foreign Lender claiming complete exemption from U.S.
federal withholding tax on all payments by the Borrower under this Agreement and
the other Loan Documents.  Such forms shall be delivered by each Foreign Lender
on or before the date it becomes a party to this Agreement.  In addition, each
Foreign Lender shall deliver such forms promptly upon the obsolescence or
invalidity of any form previously delivered by such Foreign Lender.  Each
Foreign Lender shall promptly notify the Borrower at any time it determines that
it is no longer in a position to provide any previously delivered certificate to
the Borrower (or any other form of certification adopted by the U.S. taxing
authorities for such purpose).  Notwithstanding any other provision of this
Section 2.14(e), a Foreign Lender shall not be required to deliver any form
pursuant to this Section 2.14(e) that such Foreign Lender is not legally able to
deliver.

          SECTION 2.15.  Payments Generally; Pro Rata Treatment; Sharing of
Set-offs.  (a)  The Borrower shall make each payment required to be made by it
hereunder (whether of principal, interest or fees, or under Section 2.12, 2.13
or 2.14, or otherwise) prior to 1:00 p.m., 
<PAGE>
 
                                                                              20

New York City time, on the date when due, in immediately available funds,
without set-off or counterclaim. Any amounts received after such time on any
date may, in the discretion of the Administrative Agent, be deemed to have been
received on the next succeeding Business Day for purposes of calculating
interest thereon. All such payments shall be made to the Administrative Agent at
its offices at 270 Park Avenue, New York, New York, except that payments
pursuant to Sections 2.12, 2.13 and 2.14 shall be made directly to the Persons
entitled thereto. The Administrative Agent shall distribute any such payments
received by it for the account of any other Person to the appropriate recipient
promptly following receipt thereof. If any payment hereunder shall be due on a
day that is not a Business Day, the date for payment shall be extended to the
next succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension. All payments
hereunder shall be made in dollars.

          (b)  If at any time insufficient funds are received by and available
to the Administrative Agent to pay fully all amounts of principal, interest and
fees then due hereunder, such funds shall be applied (i) first, to pay interest
and fees then due hereunder, ratably among the parties entitled thereto in
accordance with the amounts of interest and fees then due to such parties, and
(ii) second, to pay principal then due hereunder, ratably among the parties
entitled thereto in accordance with the amounts of principal then due to such
parties.

          (c)  If any Lender shall, by exercising any right of set-off or
counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its Loans resulting in such Lender receiving payment of a
greater proportion of the aggregate amount of its Loans and accrued interest
thereon than the proportion received by any other Lender, then the Lender
receiving such greater proportion shall purchase (for cash at face value)
participations in the Loans of other Lenders to the extent necessary so that the
benefit of all such payments shall be shared by the Lenders ratably in
accordance with the aggregate amount of principal of and accrued interest on
their respective Loans; provided that (i) if any such participations are
purchased and all or any portion of the payment giving rise thereto is
recovered, such participations shall be rescinded and the purchase price
restored to the extent of such recovery, without interest, and (ii) the
provisions of this paragraph shall not be construed to apply to any payment made
by the Borrower pursuant to and in accordance with the express terms of this
Agreement or any payment obtained by a Lender as consideration for the
assignment of or sale of a participation in any of its Loans to any assignee or
participant, other than to the Borrower or any Subsidiary or Affiliate thereof
(as to which the provisions of this paragraph shall apply).  The Borrower
consents to the foregoing and agrees, to the extent it may effectively do so
under applicable law, that any Lender acquiring a participation pursuant to the
foregoing arrangements may exercise against the Borrower rights of set-off and
counterclaim with respect to such participation as fully as if such Lender were
a direct creditor of the Borrower in the amount of such participation.

          (d)  Unless the Administrative Agent shall have received notice from
the Borrower prior to the date on which any payment is due to the Administrative
Agent for the account of the Lenders hereunder that the Borrower will not make
such payment, the Administrative Agent may assume that the Borrower has made
such payment on such date in accordance herewith and may, in reliance upon such
assumption, distribute to the Lenders the amount due.  In such event, if the
Borrower has not in fact made such payment, then each of the Lenders severally
agrees to repay to the Administrative Agent forthwith on demand the amount so
distributed to such Lender with interest thereon, for each day from and
including the date such amount is distributed to it to but excluding the date of
payment to the Administrative Agent, at the Federal Funds Effective Rate.

                                                                              21

          (e)  If any Lender shall fail to make any payment required to be made
by it pursuant to Section 2.04(b), then the Administrative Agent may, in its
discretion (notwithstanding any contrary provision hereof), apply any amounts
thereafter received by the Administrative Agent for the account of such Lender
to satisfy such Lender's obligations under such Section until all such
unsatisfied obligations are fully paid.

          SECTION 2.16.  Mitigation Obligations; Replacement of Lenders. (a)  If
any Lender requests compensation under Section 2.12, or if the Borrower is
required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 2.14, then such
Lender shall use reasonable efforts to designate a different lending office for
funding or booking its Loans hereunder or to assign its rights and obligations
hereunder to another of its offices, branches or affiliates, if, in the judgment
of such Lender, such designation or assignment (i) would eliminate or reduce
amounts payable pursuant to Section 2.12 or 2.14, as the case may be, in the
future and (ii) would not subject such Lender to any unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender.  The Borrower
hereby agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

          (b)  If any Lender requests compensation under Section 2.12, or if the
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.14,
or if any Lender defaults in its obligation to fund Loans hereunder, then the
Borrower may, at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in
Section 9.04), all its interests, rights and obligations under this Agreement to
an assignee that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment); provided that (i) the Borrower
shall have received the prior written consent of the Administrative Agent, which
consent shall not unreasonably be withheld, (ii) such Lender shall have received
payment of an amount equal to the outstanding principal of its Loans, accrued
interest thereon, accrued fees and all other amounts payable to it hereunder,
from the assignee (to the extent of such outstanding principal and accrued
interest and fees) or the Borrower (in the case of all other amounts) and (iii)
in the case of any such assignment resulting from a claim for compensation under
Section 2.12 or payments required to be made pursuant to Section 2.14, such
assignment will result in a reduction in such compensation or payments. A Lender
shall not be required to make any such assignment and delegation if, prior
thereto, as a result of a waiver by such Lender or otherwise, the circumstances
entitling the Borrower to require such assignment and delegation cease to apply.


III.                              ARTICLE III

                         Representations and Warranties
                         ------------------------------

          The Borrower represents and warrants to the Lenders that:

          SECTION 3.01.  Existence.  Each of the Borrower and its Subsidiaries
is duly organized, validly existing and in good standing under the laws of the
jurisdiction of its organization, has all requisite power and authority to carry
on its business as now conducted and, except where the failure to do so,
individually or in the aggregate, could not reasonably be expected to result in
a Material Adverse Effect, is qualified to do business in, and is in good
standing in, every jurisdiction where such qualification is required.
<PAGE>
 
                                                                              22

          SECTION 3.02.  Power and Authority; Enforceability.  The Transactions
are within the corporate or other organizational powers of each Credit Party and
have been duly authorized by all necessary corporate or other organizational
and, if required, stockholder action.  Each Loan Document has been duly executed
and delivered by each Credit Party party thereto and constitutes a legal, valid
and binding obligation of each such Credit Party, enforceable in accordance with
its terms, subject to applicable bankruptcy, insolvency, reorganization,
moratorium or other laws affecting creditors' rights generally and subject to
general principles of equity, regardless of whether considered in a proceeding
in equity or at law.

          SECTION 3.03.  No Conflicts; No Burdensome Restrictions.  The
Transactions (a) do not require any consent or approval of, registration or
filing with, or any other action by, any Governmental Authority, except such as
have been obtained or made and are in full force and effect, (b) will not
violate any applicable law or regulation or the charter, by-laws or other
organizational documents of the Borrower or any of its Subsidiaries or any order
of any Governmental Authority, (c) will not violate or result in a default under
any indenture, agreement or other instrument binding upon the Borrower or any of
its Subsidiaries or its assets, or give rise to a right thereunder to require
any payment to be made by the Borrower or any of its Subsidiaries, and (d) will
not result in the creation or imposition of any Lien on any asset of the
Borrower or any of its Subsidiaries. No Requirement of Law or Contractual
Obligation applicable to the Borrower or any of its Subsidiaries could
reasonably be expected to have a Material Adverse Effect.

          SECTION 3.04.  Financial Statements; Liabilities; Disclosure; No
Material Adverse Change.  (a)  The Borrower has heretofore furnished to the
Lenders its consolidated balance sheet and statements of income, stockholders
equity and cash flows (i) as of and for the fiscal year ended December 31, 1996,
reported on by Arthur Andersen LLP, independent public accountants, and (ii) as
of and for the fiscal quarter and the portion of the fiscal year ended September
30, 1997, signed by its chief financial officer.  Such financial statements
present fairly, in all material respects, the financial position and results of
operations and cash flows of the Borrower and its consolidated Subsidiaries as
of such dates and for such periods in accordance with GAAP, subject to year-end
audit adjustments and the absence of footnotes in the case of the statements
referred to in clause (ii) above.  As of the Effective Date, the Borrower and
its Subsidiaries do not have any material Guarantee obligations, contingent
liabilities and liabilities for taxes, or any long-term leases or unusual
forward or long-term commitments, including, without limitation, any material
interest rate or foreign currency swap or exchange transaction or other
obligation in respect of derivatives, that have materially changed from those
reflected, individually or in the aggregate, in either (i) the most recent
financial statements referred to in this paragraph or (ii) filings made by the
Borrower with the SEC that were publicly available prior to the Effective Date. 
During the period from December 31, 1996 to and including the date hereof there
has been no disposition by the Borrower or any of its Subsidiaries of any
material part of their business or property (determined on a consolidated basis
with respect to the Borrower and its Subsidiaries), other than dispositions
disclosed in filings made by the Borrower with the SEC that were publicly
available prior to the Effective Date.  The Borrower has disclosed to the
Lenders all agreements, instruments and corporate or other restrictions to which
it or any of its Subsidiaries is subject, and all other matters known to it,
that, individually or in the aggregate, could reasonably be expected to result
in a Material Adverse Effect.

          (b)  None of the reports, financial statements, certificates or other
information furnished by or on behalf of the Borrower to the Administrative
Agent or any Lender on or prior to the Effective Date in connection with the
negotiation of this Agreement or delivered hereunder, taken as a whole, contains
any material misstatement of fact or omits to state any material fact 
<PAGE>
 
                                                                              23

necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading; provided that, with respect to
projected financial information, the Borrower represents only that such
information was prepared in good faith based upon assumptions believed to be
reasonable at the time.

          (c)  During the period from December 31, 1996 through the Effective
Date, there has been no material adverse change in the business, assets,
operations, prospects or condition, financial or otherwise, of the Borrower and
its Subsidiaries, taken as a whole.

          (d)  In connection with the representations and warranties made by the
Borrower in this Section 3.04, the Lenders agree that the Borrower shall not be
deemed in breach of any representation or warranty in this Section 3.04 on
account of the Borrower's completing the matters or taking the actions described
in the Borrower's Quarterly Report on Form 10-Q for the quarter ended September
30, 1997, as filed with the SEC, under the heading "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Outlook", or, in
respect of any such matter or action or other matters emerging from comments
received by the Borrower from the SEC or the Borrower's ongoing review of its
accounting policies, practices or procedures, incurring charges, increasing
reserves or writing down asset values or adjusting, revising or restating
financial statements or footnotes for one or more quarters or years, so long as
the nature and amount of any such charge, reserve, write-down, adjustment,
revision or restatement are substantially within the parameters disclosed to the
Lenders prior to the Effective Date.

          SECTION 3.05.  Litigation.  Except for the Disclosed Matters, as of
the Effective Date, there are no actions, suits or proceedings by or before any
arbitrator or Governmental Authority pending against or, to the knowledge of the
Borrower, threatened against or affecting the Borrower or any of its
Subsidiaries (a) could reasonably be expected, individually or in the aggregate,
to result in a Material Adverse Effect (other than the Disclosed Matters) or (b)
that involve this Agreement or the Transactions.

          SECTION 3.06.  Property Matters.  (a)  Each of the Borrower and its
Subsidiaries has good title to, or valid leasehold interests in, all its real
and personal property material to its business, except for defects in title that
do not materially interfere with its ability to conduct its business as
currently conducted or to utilize such properties for their intended purposes,
and none of such property is subject to any Lien except as permitted by Section
6.03.

          (b)  Each of the Borrower and its Subsidiaries owns, or is licensed to
use, all trademarks, tradenames, copyrights, patents and other intellectual
property material to its business, and the use thereof by the Borrower and its
Subsidiaries does not infringe upon the rights of any other Person, except for
any such infringements that, individually or in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect.

          (c)  Except for the Disclosed Matters and except with respect to any
other matters that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect, neither the Borrower nor any of
its Subsidiaries (i) has failed to comply with any Environmental Law or to
obtain, maintain or comply with any permit, license or other approval required
under any Environmental Law, (ii) has become subject to any Environmental
Liability, (iii) has received notice of any claim with respect to any
Environmental Liability or (iv) knows of any basis for any Environmental
Liability.

          (d)  The Subsidiaries listed on Schedule 1.01 under the heading
"Material Receivables-Generating Subsidiaries" constitute each of the
Subsidiaries that, as of November 30, 1997, had aggregate outstanding accounts
receivable owing to it in excess of $20,000,000.

          SECTION 3.07.  Compliance; No Default.  Each of the Borrower and its
Subsidiaries is in compliance with all laws, regulations and orders of any
Governmental Authority applicable to it or its property and all indentures,
agreements and other instruments binding upon it or its property, except where
the failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect.  No Default has occurred and is
continuing.

          SECTION 3.08.  Investment and Holding Company Status.  Neither the
Borrower nor any of its Subsidiaries is (a) an "investment company" as defined
in, or subject to regulation under, the Investment Company Act of 1940 or (b) a
"holding company" as defined in, or subject to regulation under, the Public
Utility Holding Company Act of 1935.

          SECTION 3.09.  Taxes.  Each of the Borrower and its Subsidiaries has
timely filed or caused to be filed all Tax returns and reports required to have
been filed and has paid or caused to be paid all Taxes required to have been
paid by it, except (a) Taxes that are being contested in good faith by
appropriate proceedings and for which the Borrower or such Subsidiary, as
applicable, has set aside on its books adequate reserves or (b) to the extent
that the failure to do so could not reasonably be expected to result in a
Material Adverse Effect.

          SECTION 3.10.  Labor Matters.  Except as, in the aggregate, could not
reasonably be expected to have a Material Adverse Effect, (a) there are no
strikes or other labor disputes against the Borrower or any of its Subsidiaries
pending or, to the knowledge of the Borrower, threatened, (b) hours worked by
and payment made to employees of the Borrower and its Subsidiaries have not been
in violation of the Fair Labor Standards Act or any other applicable Requirement
of Law dealing with such matters and (c) all payments due from the Borrower or
any of its Subsidiaries on account of employee health and welfare insurance have
been paid or accrued as a liability on the books of the Borrower or the relevant
Subsidiary.

          SECTION 3.11.  ERISA.  No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events for
which liability is reasonably expected to occur, could reasonably be expected to
result in a Material Adverse Effect.  The present value of all accumulated
benefit obligations of all underfunded Plans (based on the assumptions used for
purposes of Statement of Financial Accounting Standards No. 87) did not, as of
the date of the most recent financial statements reflecting such amounts, exceed
by more than $40,000,000 the fair market value of the assets of all such
underfunded Plans.

          SECTION 4.01.  Effective Date.  The obligations of the Lenders to make

          (c) The Administrative Agent shall have received a favorable written
     opinion (addressed to the Administrative Agent and the Lenders and dated
     the Effective Date) of Winston & Strawn, counsel for the Borrower,
     substantially in the form of Exhibit D, and covering such other matters
     relating to the Borrower and its Subsidiaries, the Loan Documents or the

          SECTION 4.02.  Each Credit Event.  The obligation of each Lender to
make a Loan on the occasion of any Borrowing is subject to the satisfaction of
the following conditions:

          (a) The representations and warranties of the Credit Parties set forth
     in this Agreement (other than Sections 3.04(c) and 3.05) and the other Loan
     Documents shall be true and correct on and as of the date of such
     Borrowing.

          (b) At the time of and immediately after giving effect to such
     Borrowing, no Default shall have occurred and be continuing.

          (c) At the time of such Borrowing, the aggregate Net Investment of all
     Participants shall equal or exceed the Maximum Transfer Amount (as each
     such term is defined in the Trade Receivables Facility).

Each Borrowing shall be deemed to constitute a representation and warranty by
the Borrower on the date thereof as to the matters specified in paragraphs (a),
(b) and (c) of this Section.


V.                                 ARTICLE V

                             Affirmative Covenants

          Until the Commitments have expired or been terminated and the
principal of and interest on each Loan and all fees payable hereunder shall have

     sheet and related statements of operations, stockholders' equity and cash
     flows as of the end of and for such year, setting forth in each case in
     comparative form the figures for the previous fiscal year, in each case
     reported on by Arthur Andersen LLP or other independent public accountants
     of recognized national standing (without a "going concern" or like
     qualification or exception and without any qualification or exception as to
     the scope of such audit) to the effect that such consolidated financial
     statements present fairly in all material respects the financial condition
     and results of operations of the Borrower and its consolidated Subsidiaries
     on a consolidated basis in accordance with GAAP consistently applied;

          (b) within 60 days after the end of each of the first three fiscal
     quarters of each fiscal year of the Borrower, to the extent prepared to

     such fiscal quarter or, if no such Form 10-Q was so filed by Borrower for
     such fiscal quarter, its consolidated balance sheet and related statements
     of operations, stockholders' equity and cash flows as of the end of and for
     such fiscal quarter and the then elapsed portion of the fiscal year,
     setting forth in each case in comparative form the figures for the
     corresponding period or periods of (or, in the case of the balance sheet,
     as of the end of) the previous fiscal year, in each case certified by one
     of its Financial Officers as presenting fairly in all material respects the
     financial condition and results of operations of the Borrower and its
     consolidated Subsidiaries on a consolidated basis in accordance with GAAP
     consistently applied, subject to normal year-end audit adjustments and the
     absence of footnotes;

          (c) concurrently with any delivery of financial statements under
     clause (a) or (b) above, a certificate of a Financial Officer of the
     Borrower (i) certifying as to whether a Default has occurred and, if a
     Default has occurred, specifying the details thereof and any action taken
     or proposed to be taken with respect thereto, (ii) setting forth reasonably
     detailed calculations demonstrating compliance with Section 6.01 and, with
     respect to any items exceeding $10,000,000, Sections 6.02(a)(viii) and
     6.03(a)(vii) and (iii) stating whether any change in GAAP has had a
     material effect on the financial statements accompanying such certificate
     and specifying the nature of any such change;

          (d) promptly after the same become available, copies of all reports on
     Form 10-K, 10-Q or 8-K and all proxy statements filed by the Borrower or
     WTI with the SEC and any materials distributed by the Borrower or WTI to

          (e) promptly following any request therefor, such other information
     regarding the operations, business affairs and financial condition of the
     Borrower or any Subsidi ary, or compliance with the terms of this
     Agreement, as the Administrative Agent or any Lender may reasonably
     request.

                                                                              27

          SECTION 5.02.  Notices of Material Events.  The Borrower will furnish
to the Administrative Agent and each Lender prompt written notice of the
following:

          (a)  the occurrence of any Default;

          (b)  the filing or commencement of any action, suit or proceeding by
     or before any arbitrator or Governmental Authority against or affecting the
     Borrower or any Affiliate thereof that could reasonably be expected to
     result in a Material Adverse Effect;

          (c)  the occurrence of any ERISA Event that, alone or together with
     any other ERISA Events that have occurred, could reasonably be expected to
     result in a Material Adverse Effect; and

          (d)  any other development that results in, or could reasonably be
     expected to result in, a Material Adverse Effect.

Each notice delivered under this Section shall be accompanied by a statement of
a Financial Officer or other executive officer of the Borrower setting forth the
details of the event or development requiring such notice and any action taken
or proposed to be taken with respect thereto.

          SECTION 5.03.  Existence; Conduct of Business.  The Borrower will, and
will cause each of its Subsidiaries to, do or cause to be done all things
necessary to preserve, renew and keep in full force and effect its legal
existence and the rights, licenses, permits, privileges and franchises material
to the conduct of its business; provided that the foregoing shall not prohibit
any merger, consolidation, sale of assets, liquidation or dissolution permitted
under Section 6.04.

          SECTION 5.04.  Payment of Obligations.  The Borrower will, and will
cause each of its Subsidiaries to, pay its obligations, including Tax
liabilities, that, if not paid, could result in a Material Adverse Effect before
the same shall become delinquent or in default, except where (a) the validity or
amount thereof is being contested in good faith by appropriate proceedings, (b)
the Borrower or such Subsidiary has set aside on its books adequate reserves
with respect thereto in accordance with GAAP and (c) the failure to make payment
pending such contest could not reasonably be expected to result in a Material
Adverse Effect.

          SECTION 5.05.  Maintenance of Properties; Insurance.  The Borrower
will, and will cause each of its Subsidiaries to, (a) keep and maintain all
property material to the conduct of its business in good working order and
condition, ordinary wear and tear excepted, and (b) maintain, with financially
sound and reputable insurance companies, insurance in such amounts and against
such risks as are customarily maintained by companies engaged in the same or
similar businesses operating in the same or similar locations.

          SECTION 5.06.  Books and Records; Inspection Rights.  The Borrower
will, and will cause each of its Subsidiaries to, keep proper books of record
and account in which full, true and correct entries are made of all dealings and
transactions in relation to its business and activities.  The Borrower will,
will cause each of its Wholly Owned Subsidiaries to and, to the extent
practicable, will cause each of its other Subsidiaries to, permit any
representatives designated by the Administrative Agent or any Lender, upon
reasonable prior notice, to visit and inspect its properties, to examine and
make extracts from its books and records, and to discuss its affairs, finances
and condition with its officers and independent accountants, all at such
reasonable times and as often as reasonably requested.

          SECTION 5.07.  Compliance with Laws and Contractual Obligations. The
Borrower will, and will cause each of its Subsidiaries to, comply with all
Requirements of Law (including, without limitation, Environmental Laws) and all
Contractual Obligations applicable to it or its property, except where the
failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect.

          SECTION 5.08.  Use of Proceeds.  The proceeds of the Loans and of the
Trade Receivables Facility will be used only to finance the working capital
needs of the Borrower and its Subsidiaries in the ordinary course of business
and to refinance indebtedness of the Borrower outstanding on the Effective Date
and maturing prior to the Maturity Date and to refinance commercial paper of the
Borrower maturing prior to the Maturity Date.  No part of the proceeds of any
Loan will be used, whether directly or indirectly, for any purpose that entails
a violation of any of the Regulations of the Board, including Regulations G, U
and X.

          SECTION 5.09.  New Subsidiary Guarantors.  With respect to (a) any new
domestic Wholly Owned Subsidiary (other than captive insurance companies)
created (including any such Subsidiary surviving a merger transaction) or
acquired after the Effective Date by the Borrower that, as of the most recent
date prior to such acquisition for which the relevant information is available

rights and powers expressly contemplated hereby that the Administrative Agent is
required to exercise in writing by the Required Lenders, and (c) except as
expressly set forth herein, the Administrative Agent shall not have any duty to
disclose, and shall not be liable for the failure to disclose, any information
relating to the Borrower or any of its Subsidiaries that is communicated to or
obtained by the bank serving as Administrative Agent or any of its Affiliates in
any capacity.  The Administrative Agent shall not be liable for any action taken
or not taken by it with the consent or at the request of the Required Lenders or
in the absence of its own gross negligence or willful misconduct.  The
Administrative Agent shall be deemed not to have knowledge of any Default unless
and until written notice thereof is given to the Administrative Agent by the
Borrower or a Lender, and the Administrative Agent shall not be responsible for
or have any duty to ascertain or inquire into (i) any statement, warranty or
representation made in or in connection with this Agreement or any other Loan
Document, (ii) the contents of any certificate, report or other document
delivered hereunder or in connection herewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set
forth herein or in any other Loan Document, (iv) the validity, enforceability,
effectiveness or genuineness of this Agreement, any other Loan Document

                                                                              36

or any other agreement, instrument or document, or (v) the satisfaction of any
condition set forth in Article IV or elsewhere herein, other than to confirm
receipt of items expressly required to be delivered to the Administrative Agent.

          The Administrative Agent shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by the proper Person.  The Administrative Agent
also may rely upon any statement made to it orally or by telephone and believed
by it to be made by the proper Person, and shall not incur any liability for
relying thereon.  The Administrative Agent may consult with legal counsel (who
may be counsel for the Borrower), independent accountants and other experts
selected by it, and shall not be liable for any action taken or not taken by it
in accordance with the advice of any such counsel, accountants or experts.

          The Administrative Agent may perform any and all its duties and
exercise its rights and powers by or through any one or more sub-agents
appointed by the Administrative Agent.  The Administrative Agent and any such
sub-agent may perform any and all its duties and exercise its rights and powers
through their respective Related Parties.  The exculpatory provisions of the
preceding paragraphs shall apply to any such sub-agent and to the Related
Parties of the Administrative Agent and any such sub-agent, and shall apply to
their respective activities in connection with the syndication of the credit
facilities provided for herein as well as activities as Administrative Agent.

          Subject to the appointment and acceptance of a successor
Administrative Agent as provided in this paragraph, the Administrative Agent may
resign at any time by notifying the Lenders and the Borrower. Upon any such
resignation, the Required Lenders shall have the right, in consultation with the
Borrower, to appoint a successor.  If no successor shall have been so appointed
by the Required Lenders and shall have accepted such appointment within 30 days
after the retiring Administrative Agent gives notice of its resignation, then
the retiring Administrative Agent may, on behalf of the Lenders, appoint a
successor Administrative Agent which shall be a bank with an office in New York,
New York, or an Affiliate of any such bank.  Upon the acceptance of its
appointment as Administrative Agent hereunder by a successor, such successor
shall succeed to and become vested with all the rights, powers, privileges and
duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations hereunder.  The fees
payable by the Borrower to a successor Administrative Agent shall be the same as
those payable to its predecessor unless otherwise agreed between the Borrower
and such successor.  After the Administrative Agent's resignation hereunder, the
provisions of this Article and Section 9.03 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 Administrative Agent.

          Each Lender acknowledges that it has, independently and without
reliance upon the Administrative Agent or any other Lender and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement.  Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any related agreement or any document furnished hereunder or thereunder.

IX.                                ARTICLE IX

                                 Miscellaneous
                                 -------------

          SECTION 9.01.  Notices.  Except in the case of notices and other
communications expressly permitted to be given by telephone, all notices and
other communications provided for herein shall be in writing and shall be
delivered by hand or overnight courier service, mailed by certified or
registered mail or sent by telecopy, as follows:

          (a) if to the Borrower, to it at 3003 Butterfield Road, Oak Brook,
     Illinois 60523, Attention of Vice President - Finance (Telecopy No. 
     630-572-1340);

          (b) if to the Administrative Agent, to The Chase Manhattan Bank, Agent
     Bank Services Group, 1 Chase Manhattan Plaza, New York, New York 10081,
     Attention of Janet Beldon (Telecopy No. (212) 552-5662), with a copy to The
     Chase Manhattan Bank, 270 Park Avenue, New York, New York 10017, Attention
     of Joe Lillis (Telecopy No. (212) 270-1063); and

          (c) if to any other Lender, to it at its address (or telecopy number)
     set forth in its Administrative Questionnaire.

Any party hereto may change its address or telecopy number for notices and other
communications hereunder by notice to the other parties hereto. All notices and
other communications given to any party hereto in accordance with the provisions
of this Agreement shall be deemed to have been given on the date of receipt.

          SECTION 9.02.  Waivers; Amendments.  (a)  No failure or delay by the
Administrative Agent or any Lender in exercising any right or power hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right or power, or any abandonment or discontinuance of steps to
enforce such a right or power, preclude any other or further exercise thereof or
the exercise of any other right or power.  The rights and remedies of the
Administrative Agent and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies that they would otherwise have.  No waiver
of any provision of this Agreement or consent to any departure by the Borrower
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. 
Without limiting the generality of the foregoing, the making of a Loan shall not
be construed as a waiver of any Default, regardless of whether the
Administrative Agent or any Lender may have had notice or knowledge of such
Default at the time.

          (b)  Neither this Agreement, any other Loan Document nor any provision
hereof or thereof may be waived, amended or modified except pursuant to an
agreement or agreements in writing entered into by each Credit Party party
thereto and the Required Lenders or by each Credit Party party thereto and the
Administrative Agent with the consent of the Required Lenders; provided that no
such agreement shall (i) increase the Commitment of any Lender without the
written consent of such Lender, (ii) reduce the principal amount of any Loan or
reduce the rate of interest thereon, or reduce any fees payable hereunder,
without the written consent of each Lender directly affected thereby, (iii)
postpone the scheduled date of payment of the principal amount of any Loan, or
any interest thereon, or any fees payable hereunder, or reduce the amount of,
waive or excuse any such payment, or postpone the scheduled date of expiration
of any Commitment, without the written consent of each Lender directly affected
thereby, (iv) release all or 
<PAGE>
 
                                                                              38

substantially all of the Subsidiary Guarantors from their obligations under the
Subsidiary Guarantee, without the written consent of each Lender, or (v) change
any of the provisions of this Section or the definition of "Required Lenders" or
any other provision hereof specifying the number or percentage of Lenders
required to waive, amend or modify any rights hereunder or make any
determination or grant any consent hereunder, without the written consent of
each Lender; provided further that no such agreement shall amend, modify or
otherwise affect the rights or duties of the Administrative Agent hereunder
without the prior written consent of the Administrative Agent.

          (c)  Each Lender agrees that, in the event that any transaction that
would be prohibited by Section 6.03, Section 6.05 (in the case of repurchases of
capital stock) or Section 6.07 is consummated or proposed to be consummated by a
non-Wholly Owned Subsidiary as a result of recommendations by management or the
independent members of the board of directors of such Subsidiary, such Lender
will not unreasonably withhold its consent to any request by the Borrower to
effectuate appropriate modifications to this Agreement permitting such
transaction, subject to satisfaction of any conditions such Lender reasonably
deems appropriate in connection therewith.

          SECTION 9.03.  Expenses; Indemnity; Damage Waiver.  (a)  The Borrower
agrees to pay (i) all reasonable out-of-pocket expenses incurred by the
Administrative Agent and its Affiliates, including the reasonable fees, charges
and disbursements of counsel for the Administrative Agent, in connection with
the syndication of the credit facilities provided for herein, the preparation
and administration of this Agreement or any amendments, modifications or waivers
of the provisions of this Agreement or any other Loan Document (whether or not
the transactions contemplated hereby or thereby shall be consummated) and (ii)
all out-of-pocket expenses incurred by the Administrative Agent or any Lender,
including the fees, charges and disbursements of any counsel (including the
reasonably documented and allocated cost of internal counsel) for the
Administrative Agent or any Lender, in connection with the enforcement or
protection of its rights in connection with this Agreement or any other Loan
Document, including its rights under this Section, or in connection with the
Loans made hereunder, including in connection with any workout, restructuring or
negotiations in respect thereof.

          (b)  The Borrower agrees to indemnify the Administrative Agent and
each Lender, and each Related Party of any of the foregoing Persons (each such
Person being called an "Indemnitee") against, and hold each Indemnitee harmless
from, any and all losses, claims, damages, liabilities and related expenses,
including the fees, charges and disbursements of any counsel for any Indemnitee,
incurred by or asserted against any Indemnitee arising out of, in connection
with, or as a result of (i) the execution or delivery of this Agreement, any
other Loan Document or any agreement or instrument contemplated hereby or
thereby, the performance by the parties hereto or thereto of their respective
obligations hereunder or thereunder or the consummation of the Transactions or
any other transactions contemplated hereby or thereby, (ii) any Loan or the use
of the proceeds therefrom, (iii) any actual or alleged presence or release of
Hazardous Materials on or from any property owned or operated by the Borrower or
any of its Subsidiaries, or any Environmental Liability related in any way to
the Borrower or any of its Subsidiaries, or (iv) any actual or prospective
claim, litigation, investigation or proceeding relating to any of the foregoing,
whether based on contract, tort or any other theory and regardless of whether
any Indemnitee is a party thereto; provided that such indemnity shall not, as to
any Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or willful misconduct of such Indemnitee.

                                                                              39

          (c)  To the extent that the Borrower fails to pay any amount required
to be paid by it to the Administrative Agent under paragraph (a) or (b) of this
Section, each Lender severally agrees to pay to the Administrative Agent such
Lender's Applicable Percentage (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount;
provided that the unreimbursed expense or indemnified loss, claim, damage,
liability or related expense, as the case may be, was incurred by or asserted
against the Administrative Agent in its capacity as such.

          (d)  To the extent permitted by applicable law, the Borrower shall not
assert, and hereby waives, any claim against any Indemnitee, on any theory of
liability, for special, indirect, consequential or punitive damages (as opposed
to direct or actual damages) arising out of, in connection with, or as a result
of, this Agreement or any agreement or instrument contemplated hereby, the
Transactions, any Loan or the use of the proceeds thereof.

          (e)  All amounts due under this Section shall be payable not later
than 10 days after written demand therefor.

          SECTION 9.04.  Successors and Assigns.  (a)  The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns permitted hereby, except that the
Borrower may not assign or otherwise transfer any of its rights or obligations
hereunder without the prior written consent of each Lender (and any attempted
assignment or transfer by the Borrower without such consent shall be null and
void).  Nothing in this Agreement, expressed or implied, shall be construed to
confer upon any Person (other than the parties hereto, their respective
successors and assigns permitted hereby and, to the extent expressly
contemplated hereby, the Related Parties of each of the Administrative Agent and
the Lenders) any legal or equitable right, remedy or claim under or by reason of
this Agreement.

          (b)  Any Lender may assign to one or more assignees all or a portion
of its rights and obligations under this Agreement (including all or a portion
of its Commitment and the Loans at the time owing to it); provided that (i)
except in the case of an assignment to a Lender or an Affiliate of a Lender,
each of the Borrower and the Administrative Agent must give their prior written
consent to such assignment (which consent shall not be unreasonably withheld),
(ii) except in the case of an assignment to a Lender or an Affiliate of a Lender
or an assignment of the entire remaining amount of the assigning Lender's
Commitment or Loans, the amount of the Commitment of the assigning Lender
subject to each such assignment (determined as of the date the Assignment and
Acceptance with respect to such assignment is delivered to the Administrative
Agent) shall not be less than $5,000,000 unless each of the Borrower and the
Administrative Agent otherwise consent, (iii) the parties to each assignment
shall execute and deliver to the Administrative Agent an Assignment and
Acceptance, together with a processing and recordation fee of $3,500, and (iv)
the assignee, if it shall not be a Lender, shall deliver to the Administrative
Agent an Administrative Questionnaire; provided further that any consent of the
Borrower otherwise required under this paragraph shall not be required if an
Event of Default under clause (h) or (i) of Article VII has occurred and is
continuing.  Upon acceptance and recording pursuant to paragraph (d) of this
Section, from and after the effective date specified in each Assignment and
Acceptance, the assignee thereunder shall be a party hereto and, to the extent
of the interest assigned by such Assignment and Acceptance, have the rights and
obligations of a Lender under this Agreement, and the assigning Lender
thereunder shall, to the extent of the interest assigned by such Assignment and
Acceptance, be released from its obligations under this Agreement (and, in the
case of an Assignment and Acceptance covering all of the assigning Lender's
rights and obligations under this Agreement, such Lender shall cease to be a
party hereto but shall continue to be entitled to the benefits of Sections 2.12,
2.13, 2.14 and 9.03).  Any assignment or transfer by

                                                                              40

a Lender of rights or obligations under this Agreement that does not comply with
this paragraph shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with
paragraph (e) of this Section.

          (c)  The Administrative Agent, acting for this purpose as an agent of
the Borrower, shall maintain at one of its offices in The City of New York a
copy of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitment of,
and principal amount of the Loans owing to, each Lender pursuant to the terms
hereof from time to time (the "Register").  The entries in the Register shall be
conclusive, and the Borrower, the Administrative Agent and the Lenders may treat
each Person whose name is recorded in the Register pursuant to the terms hereof
as a Lender hereunder for all purposes of this Agreement, notwithstanding notice
to the contrary.

          (d)  Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, the assignee's completed
Administrative Questionnaire (unless the assignee shall already be a Lender
hereunder), the processing and recordation fee referred to in paragraph (b) of
this Section and any written consent to such assignment required by paragraph
(b) of this Section, the Administrative Agent shall accept such Assignment and
Acceptance and record the information contained therein in the Register.  No
assignment shall be effective for purposes of this Agreement unless it has been
recorded in the Register as provided in this paragraph.

          (e)  Any Lender may, without the consent of the Borrower or the
Administrative Agent, sell participations to one or more banks or other entities
(a "Participant") in all or a portion of such Lender's rights and obligations
under this Agreement (including all or a portion of its Commitment and the Loans
owing to it); provided that (i) such Lender's obligations under this Agreement
shall remain unchanged, (ii) such Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations and (iii) the
Borrower, the Administrative Agent and the Lenders shall continue to deal solely
and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement.  Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, modification or waiver
described in the first proviso to Section 9.02(b) that affects such Participant.
Subject to paragraph (f) of this Section, the Borrower agrees that each
Participant shall be entitled to the benefits of Sections 2.12, 2.13 and 2.14 to
the same extent as if it were a Lender and had acquired its interest by
assignment pursuant to paragraph (b) of this Section.

          (f)  A Participant shall not be entitled to receive any greater
payment under Section 2.12 or 2.14 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant,
unless the sale of the participation to such Participant is made with the
Borrower's prior written consent.  A Participant that would be a Foreign Lender
if it were a Lender shall not be entitled to the benefits of Section 2.14 unless
the Borrower is notified of the participation sold to such Participant and such
Participant agrees, for the benefit of the Borrower, to comply with Section
2.14(e) as though it were a Lender.

          (g)  Prior to disclosing information relating to the Borrower and its
Subsidiaries to any proposed assignee or Participant, each Lender shall cause
such proposed assignee or Participant to enter into a confidentiality agreement
substantially in the form previously executed and delivered by such Lender or
otherwise acceptable to the Borrower.

                                                                              41

          (h)  Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement to secure obligations
of such Lender, including any such pledge or assignment to a Federal Reserve
Bank, and this Section shall not apply to any such pledge or assignment of a
security interest; provided that no such pledge or assignment of a security
interest shall release a Lender from any of its obligations hereunder or
substitute any such assignee for such Lender as a party hereto.

          SECTION 9.05.  Survival.  All covenants, agreements, representations
and warranties made by the Borrower herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement shall be
considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the making of any
Loans, regardless of any investigation made by any such other party or on its
behalf and notwithstanding that the Administrative Agent or any Lender may have
had notice or knowledge of any Default or incorrect representation or warranty
at the time any credit is extended hereunder, and shall continue in full force
and effect as long as the principal of or any accrued interest on any Loan or
any fee or any other amount payable under this Agreement is outstanding and
unpaid and so long as the Commitments have not expired or terminated.  The
provisions of Sections 2.12, 2.13, 2.14 and 9.03 and Article VIII shall survive
and remain in full force and effect regardless of the consummation of the
transactions contemplated hereby, the repayment of the Loans, the expiration or
termination of the Commitments or the termination of this Agreement or any
provision hereof.

          SECTION 9.06.  Counterparts; Integration; Effectiveness.  This
Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall constitute an original, but all of
which when taken together shall constitute a single contract.  This Agreement
and any separate letter agreements with respect to fees payable to the
Administrative Agent constitute the entire contract among the parties relating
to the subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof.  Except
as provided in Section 4.01, this Agreement shall become effective when it shall
have been executed by the Administrative Agent and when the Administrative Agent
shall have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns.  Delivery of an executed counterpart of a signature page
of this Agreement by telecopy shall be effective as delivery of a manually
executed counterpart of this Agreement.

          SECTION 9.07.  Severability.  Any provision of this Agreement held to
be invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

          SECTION 9.08.  Right of Setoff.  If an Event of Default shall have
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of the Borrower against any of and all the
obligations of the Borrower now or hereafter existing under this Agreement held
by such Lender, irrespective of whether or not such Lender shall have made any
demand under this Agreement and although such obligations may be unmatured.  The
rights of each Lender under this Section are in addition to other rights and
remedies (including other rights of setoff) which such Lender may have.

          SECTION 9.09.  Governing Law; Jurisdiction; Consent to Service of
Process.  (a)  This Agreement shall be construed in accordance with and governed
by the law of the State of New York.

          (b)  The Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of the Supreme Court
of the State of New York sitting in New York County and of the United States
District Court of the Southern District of New York, and any appellate court
from any thereof, in any action or proceeding arising out of or relating to this
Agreement, or for recognition or enforcement of any judgment, and each of the
parties hereto hereby irrevocably and unconditionally agrees that all claims in
respect of any such action or proceeding may be heard and determined in such New
York State or, to the extent permitted by law, in such Federal court.  Each of
the parties hereto 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.  Nothing in this Agreement
shall affect any right that the Administrative Agent or any Lender may otherwise
have to bring any action or proceeding relating to this Agreement against the
Borrower or its properties in the courts of any jurisdiction.

          (c)  The Borrower hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection which it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement in any court referred to
in paragraph (b) of this Section.  The Borrower hereby irrevocably waives, to
the fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

          (d)  The Borrower irrevocably consents to service of process in the
manner provided for notices in Section 9.01.  Nothing in this Agreement will
affect the right of any party to this Agreement to serve process in any other
manner permitted by law.

          SECTION 9.10.  WAIVER OF JURY TRIAL.  EACH PARTY HERETO HEREBY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A
TRIAL BY JURY IN  ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

          SECTION 9.11.  Headings.  Article and Section headings and the Table
of Contents used herein are for convenience of reference only, are not part of
this Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

          SECTION 9.12.  Confidentiality.  Each Lender agrees to maintain the
confidentiality of information furnished to it by or on behalf of the Borrower
in connection with the Transactions as provided in any separate confidentiality
agreement entered into between the Borrower and such Lender.

          (j)  Participating Subsidiary:  Waste Management of North America,

Service of an Inactive Participant shall be determined on the date immediately
preceding the date the Participant became an Inactive Participant.

               (ii) Eligibility Service: A Participant's period of service from
                    -------------------
the date the Participant commenced or recommenced participation in the Plan or
such earlier date as is approved by the Committee at the time the Participant is
designated as such, and ending on the later of the date the Participant ceases
to be a Participant hereunder by reason of retirement, death or termination of
employment or the date the Participant ceases to be a Transferred Participant or

Retirement Plan

                                                                               3
<PAGE>
 
prior to its merger into the Plan shall be counted as Eligibility Service
hereunder.
     Notwithstanding any provision contained herein to the contrary, but subject
to the break in service rules of the Pension Plan with respect to the
determination of Benefit Service, all periods of service shall be aggregated.

All other terms used in both this Plan and in the Pension Plan shall have the
same meaning as in the Pension Plan, and all actuarial calculations under this
Plan shall be made on the same basis as for the similar purpose under the
Pension Plan.

     2.   Purpose.  The purpose of this Plan is to provide a retirement income
          -------                                                             
to eligible executives of the Company and its subsidiaries to supplement the
pensions payable under the Company's Pension Plan.

     3.   Eligibility.  Effective July 1, 1997, any person who is designated as
          -----------                                                          
Level F or above under the Company's compensation administration system and who
is a participant in the Pension Plan shall be eligible to be a Participant in
this Plan, unless the Committee shall affirmatively act to exclude the
individual.  In addition, the Committee may in its discretion from time to time
designate other key employees of the Company or any Participating Subsidiary as
eligible to participate, or to continue participating, in the Plan.

     4.   Eligibility for Benefits.  Benefits under this Plan shall be payable
          ------------------------                                            
in respect of a Participant only if the Participant's termination of employment
(for reasons other than death or Disability) occurs on or after the date such
Participant has completed ten years of Eligibility Service, either as a
Participant or an Inactive Participant, as evidenced in the records of the
Committee.  In the event of the Participant's termination of employment for
reason of death or Disability, such Participant shall be entitled to receive his
or her accrued benefit under the Plan in such manner and at such time as
provided in Section 7 of the Plan.

     5.   Amount of Benefits.
          ------------------ 

          (a)  Normal Retirement.  If a Participant retires after having become
               -----------------                                               
eligible for benefits hereunder and on or after such Participant's Normal
Retirement Date, the monthly amount of such Participant's benefits under the
Plan, commencing on or after Normal Retirement Date, shall be (i) 1-1/2% of
Final Average Compensation per year of Benefit Service, reduced by (ii) the
amount of such Participant's monthly benefit under the Pension Plan (determined
without regard to any qualified domestic relations order to which such
Participant's benefit under the Pension Plan is or was subject).

          (b)  Early Retirement.  If a Participant retires or terminates
               ----------------                                         
employment after having become eligible for benefits hereunder, but before his
or her Normal Retirement Date, the monthly amount of such Participant's benefits
shall be determined in accordance with Section 5(a), except that if the
Participant has completed less than 30 years of Benefit Service such amount
shall be reduced at the rate of 2/10 of 1% for each of the first 60 months by
which the benefit commencement date precedes the Participant's Normal Retirement
Date, and for each

                                                                               4
<PAGE>
 
additional month at such rate as is determined by the Committee in its
discretion. Notwithstanding the foregoing sentence, the

                                                                               5
<PAGE>
 
Committee in its discretion may determine with respect to any particular
Participant that any such reduction shall be at a lower rate or that no such
reduction shall apply.

          (c)  Inactive Participants.  Effective July 1, 1997, notwithstanding
               ---------------------                                          
any other provision of this Section 5 to the contrary, the benefit of a
Participant who is an Inactive Participant at the time of retirement or
termination of service with the Company or an affiliated entity shall be
determined as follows:  (i) if the individual became an Inactive Participant
after having completed ten years of Eligibility Service, the monthly amount of
benefits under the Plan shall be based on the provisions of Subsections 5(a) and
(b) as of the date immediately preceding the date the Participant became an
Inactive Participant, based on Benefit Service, Final Average Compensation and
the Participant's accrued benefit under the Pension Plan as of such date; and
(ii) if the individual became an Inactive Participant before having completed
ten years of Eligibility Service, the monthly amount of benefits under the Plan
commencing on or after Normal Retirement Age shall be 0.5% of Final Average
Compensation per year of Eligibility Service completed prior to his designation
as an Inactive Participant, with no offset for the pension received under the
Pension Plan;  provided, however, that the Inactive Participant completes ten
years of Eligibility Service prior to his retirement or termination of service.

     6.   Disability.  If a Participant's employment is terminated because of
          ----------                                                         
Disability after having become eligible for benefits hereunder, but before
Normal Retirement Date, such Participant shall be eligible to receive a benefit
under the Plan beginning on his Normal Retirement Date.  The amount of benefit
under this Plan to such a Participant shall be determined in accordance with
Section 5, but shall be reduced for any year by any benefits payable to the
Participant for that year under any long-term disability program maintained or
contributed to by the Company or a Participating Subsidiary.  In computing the
Benefit Service of such a Participant, his Service shall include the period of
Disability determined in the same manner as for purposes of the Pension Plan.

     7.   Payment of Benefits.  Payment of a Participant's benefits under this
          -------------------                                                 
Plan shall begin as of the same date as such Participant's pension commencement
date under the Pension Plan, unless an earlier commencement date is specifically
approved by the Committee, in which case the Committee shall provide for such
adjustment in the amount of benefits as it determines in its discretion to be
appropriate.  Payment of such benefits shall be in the form of a straight life
annuity and shall continue thereafter monthly for the Participant's life.
However, if payment of a Participant's pension under the Pension Plan is to be
made in the form of a qualified joint and survivor annuity or in any other
optional form, the benefits under this Plan shall be paid in that same form, in
an amount actuarially equivalent to the straight life annuity otherwise payable
hereunder, and with the same contingent annuitant or contingent beneficiary as
under the Pension Plan.

     8.   Surviving Spouse Benefit.
          ------------------------ 

          (a)  If a Participant dies (i) after having become eligible for
benefits hereunder

                                                                               6
<PAGE>
 
and (ii) either (A) before termination of employment or (B) after termination of
employment and before the commencement of benefits under the Plan, provided in
case (B), the Participant and his or her spouse had not effectively waived the
qualified joint and survivor annuity under the Pension Plan, the Participant's
surviving spouse shall be eligible to receive a monthly benefit for life.

          (b)  Such surviving spouse benefit shall be in the monthly amount that
would have been payable under this Plan to the Participant's surviving spouse
under the qualified joint and survivor annuity described in Section 7 if:

               (i)  in the case of a Participant who dies after attaining the
"earliest benefit commencement date" (as defined below), the Participant had
retired on the day before his or her death and elected to commence receiving
benefits under this Plan as of such date, or

               (ii) in the case of a Participant who dies on or before the
earliest benefit commencement date, the Participant had lived and begun to
receive benefits under this Plan on the earlier benefit commencement date and
had died on the day after that date,

calculated in either case on the basis of the Participant's Final Average
Compensation and Benefit Service as of the date of death or termination of
employment, whichever is earlier, or the date the Participant became an Inactive
Participant, if applicable.  For purposes of this Section 8(b), a Participant's
"earliest benefit commencement date" is the first day of the month coinciding
with or next following the later of (A) such Participant's 55th birthday or (B)
completion of ten years of participation hereunder.

          (c)  Payment of the surviving spouse benefit hereunder shall begin as
of the same date as the spouse's benefit payable to the surviving spouse under
the Pension Plan, unless an earlier commencement date is specifically approved
by the Committee, in which case the Committee shall provide for such adjustment
in the amount of benefit as it determines in its discretion to be appropriate.
Payment of such surviving spouse benefit shall continue thereafter monthly for
the spouse's life.  However, if the payment of the surviving spouse's benefit
under the Pension Plan is to be made in some other form, the benefits under this
Plan shall be paid in that same form, in an amount actuarially equivalent to the
annuity otherwise payable hereunder, as under the Pension Plan.

     9.   Conditions on Benefits.  If a Participant engages in competition with
          ----------------------                                               
the Company or any affiliated entity (without prior authorization in writing) or
is discharged for cause, or performs acts of willful malfeasance or gross
negligence in a matter of material importance to the Company or any affiliated
entity, benefits payable thereafter to the Participant or such Participant's
surviving spouse shall be forfeited at the discretion of the Company's Board of
Directors and the Company shall have no further obligation to the Participant or
spouse under the Plan.

     10.  Re-employment.  If a retired Participant is re-employed by the Company
          -------------                                                         
or a Participating Subsidiary, no benefits shall be payable during the period of
re-employment, and

                                                                               7
<PAGE>
 
the benefits payable following subsequent retirement shall be calculated so as
to take into account such Participant's additional period of service and Final
Average Compensation, with appropriate actuarial adjustment for any benefits
paid under the Plan following such Participant's earlier retirement; provided,
however, that the amount of such benefit as recalculated, before taking into
account any such actuarial adjustment, shall not be less than such Participant's
benefit immediately following such Participant's earlier retirement.

     11.  Administration and Interpretation.  The Committee shall be the Plan
          ---------------------------------                                  
administrator.  The Committee shall have the authority to control and manage the
operation and administration of the Plan, to adopt rules and regulations
regarding the administration of the Plan, to interpret the Plan, to determine
the conditions subject to which any benefits may be payable, and to make any
other determinations which the Committee believes are necessary or advisable for
the administration of the Plan.  The Committee shall be entitled to rely
conclusively upon all tables, valuations, certificates, opinions and reports
furnished by any actuary, accountant, controller, counsel or other person
employed or engaged by the Committee with respect to the Plan.  Determinations
by the Committee shall be final and binding on all parties with respect to all
matters relating to the Plan.  The Committee may delegate all or any part of its
authority to any officer of the Company.

     12.  Claims Procedure.
          ---------------- 

          (a)  If a Participant or other person believes that such person is
entitled to benefits under the Plan, such person may file a claim for benefits
in writing with the Committee.  If a claim for benefits is wholly or partially
denied, the Committee shall give the claimant written notice of the denial
within a reasonable period of time after receipt of the claim by the Committee.
Such notice shall set forth:

               (i)    the specific reason or reasons for the denial,

               (ii)   specific reference to pertinent provisions of the Plan on
                      which the denial is based,

               (iii)  a description of any additional material or information
                      necessary for the claimant to perfect the claim and an
                      explanation of why such material or information is
                      necessary, and

               (iv)   an explanation of the claim review procedure.

          (b)  A claimant whose claim is denied, or such claimant's duly
authorized representative, may submit a written request for review to the
Committee within 60 days after receiving notice of the denial.  In connection
with such request, the claimant or his authorized representatives may review
pertinent documents and may submit issues and comments in writing.  If such a
request is made, the Committee shall make a full and fair review of the denial
of the

                                                                               8
<PAGE>
 
claim and shall make a decision not later than 60 days after receipt of the
request, unless special circumstances (such as the need to hold a hearing)
require an extension of time for processing, in which case a decision shall be
rendered as soon as possible, but not later than 120 days after receipt of the
request. The decision on review shall be in writing and shall include specific
reasons for the decision and specific references to the pertinent provisions of
the Plan on which the decision is based.

     13.  Amendment and Termination.  The Plan may be amended or terminated at
          -------------------------                                           
any time by action of the Company's Board of Directors or the Compensation and
Stock Option Committee thereof.  However, no such action shall, without the
consent of the Participant, reduce or impair the benefits then currently payable
to a Participant or surviving spouse, nor divest a Participant of any benefits
such Participant would have been entitled to receive had such Participant
resigned from the Company's employ immediately before the effective date of the
amendment or termination.

     14.  Miscellaneous.
          ------------- 

          (a)  Spendthrift provision. No interest of any person or entity in, or
               ---------------------
right to receive a benefit under the Plan shall be subject in any manner to
sale, transfer, assignment, pledge, attachment, garnishment, or other alienation
or encumbrance of any kind; nor may such interest or right to receive a benefit
be taken, either voluntarily or involuntarily, for the satisfaction of the debts
of, or other obligations or claims against, such person or entity, including
claims for alimony, support, separate maintenance and claims in bankruptcy
proceedings.

          (b)  No Guarantee of Employment.  Nothing in the Plan shall be
               --------------------------                               
construed as a contract of employment or be deemed to confer upon any
Participant the right to be retained in the service of the Company or any
affiliated entity, nor shall it interfere with the right of the Company or any
affiliated entity to discharge or otherwise deal with any Participant without
regard to the existence of this Plan.

          (c)  No Funding.  The Plan shall at all times be entirely unfunded and
               ----------                                                       
no provision shall at any time be made with regard to segregating any assets of
the Company for payment of any benefits hereunder.  All benefits under the Plan
are payable, as and when they come due, solely from the general assets of the
Company.  No Participant, surviving spouse or other person shall have any
interest in any particular assets of the Company by reason of the right to
receive a benefit under the Plan and any such Participant, surviving spouse or
other person shall have only the rights of a general unsecured creditor of the
Company with respect to any rights under the Plan.  Nothing contained in the
Plan shall constitute a guaranty by the Company or any other entity or person
that the assets of the Company will be sufficient to pay any benefit hereunder.

          (d)  Facility of Payment.  When, in the Committee's opinion, a
               -------------------                                      
Participant or surviving spouse is under a legal disability or is incapacitated
in any way so as to be unable to

                                                                               9
<PAGE>
 
manage his or her affairs, the benefits hereunder may be paid to the Participant
or spouse, or to a duly appointed guardian or conservator, custodian, adult
relative, or directly for the benefit, of the Participant or surviving spouse,
as the Committee shall in its discretion determine. Any such payments shall
constitute a complete discharge therefor with respect to the Plan, the Committee
and the Company.

          (e)  Withholding for Taxes.  Notwithstanding any other provisions of
               ---------------------                                          
this Plan, all payments hereunder shall be subject to any applicable withholding
for all federal, state and local taxes.

          (f)  Corporate successors.  The Plan shall not be automatically
               --------------------                                      
terminated by a transfer or sale of assets of the Company or by the merger or
consolidation of the Company into or with any other corporation or other entity,
but the Plan shall be continued after such sale, merger or consolidation only if
and to the extent that the transferee, purchaser or successor entity agrees to
continue the Plan.  In the event that the Plan is not continued by the
transferee, purchaser or successor entity, then the Plan shall terminate.

          (g)  Unclaimed benefit.  Each Participant shall keep the Company
               -----------------                                          
informed of his current address and the current address of his spouse.  The
Committee shall not be obligated to search for the whereabouts of any person.
If the location of a Participant is not made known to the Company within three
years after the date on which payment of the Participant's benefit may first be
made, payment may be made as though the Participant had died at the end of the
three-year period.  If, within one additional year after such three-year period
has elapsed, or, within three years after the actual death of a Participant, the
Committee is unable to locate any surviving spouse of the Participant, then the
Company shall have no further obligation to pay any benefit hereunder to such
Participant or surviving spouse or any other person and such benefit shall be
irrevocably forfeited.

          (h)  Limitations on liability.  Notwithstanding any of the preceding
               ------------------------                                       
provisions of the Plan, neither the Company nor any individual acting as an
employee or agent of the Company shall be liable to any Participant, former
Participant, surviving spouse or any other person for any claim, loss, liability
or expense incurred in connection with the Plan.

               -------------                                               
according to the laws of the State of Illinois to the extent that such laws are
not preempted by the laws of the United States of America.

          (j)  Gender and Number.  In the Plan, wherever the context admits,
               -----------------                                            
words in the singular include the plural and words in the plural include the
singular, and masculine terms shall be deemed to include the feminine.

          (k)  Headings.  The headings of sections are included solely for
               --------                                                   
convenience of reference, and if there is any conflict between such headings and
the text of the Plan, the text shall control.

                                                                              10

time, attention, and energy to the business of the Employer and the Executive
shall not be engaged in any other business activity pursued for gain, profit, or
other pecuniary advantage which activity interferes with the Executive's duties

     5. NON-COMPETITION AND NON-SOLICITATION. Executive agrees that:
          ------------------------------------                          

        (a) During the Term and for a period of one year thereafter or during
any Severance Period, if longer (the "Restricted Period"), Executive agrees that
he will not (without the written consent of the Chairman of the Board) engage
directly or indirectly in any business within the United States (financially as
an investor or lender or as an employee, director, officer, partner, independent
contractor, consultant or owner or in any other capacity calling for the
rendition of personal services or acts of management, operation or control)
which is directly competitive with the business at any time during the
Restricted Period conducted by the Company or any of its subsidiaries or
Affiliates as defined below. Notwithstanding the foregoing, Executive shall be
entitled to own securities of any corporation conducting a business competitive
with the business of the Company or any of its subsidiaries or Affiliates so
long as the securities of such corporation are listed on a national securities
exchange and the securities owned directly or indirectly by Executive do not
represent more than two percent (2%) of any class of the outstanding securities
of such company.

        (b) During the Restricted Period, in addition to the obligations
pursuant to Subsection 5(a), Executive agrees that neither he nor any business
in which he engages directly or indirectly will (i) directly or indirectly
induce any customers of the Company or of corporations or businesses which
directly or indirectly control or are controlled by or under common control with
the Company ("Affiliates") to patronize any business similar to that of the
Company, (ii) canvass, solicit or accept any similar business from any customer
of the Company or any Affiliates, (iii)

Affiliates to withdraw, curtail or cancel such customer's business with the
Company or Affiliates, (iv) directly or indirectly disclose to any other person,
firm or corporation the names or addresses of any of the customers of the
Company or Affiliates, or (v) compete with the Company or Affiliates in
acquiring or merging with any other business or acquiring the assets of such
other business.

        (c) During the Restricted Period, in addition to the obligations
pursuant to Subsections 5(a) and 5(b), Executive agrees that neither he nor any
business in which [he/she] engages directly or indirectly will (i) hire or
attempt to hire any employee of the Company or its Affiliates nor (ii) directly
or indirectly encourage any employee of the Company or its Affiliates to
terminate employment with the Company or its Affiliates. Notwithstanding the
foregoing, it shall not be deemed a violation of this subsection if a business
which employs Executive hires or attempts to hire an employee of the Company or
its Affiliates and Executive has no knowledge of, control over or involvement
with such solicitation.

        (d) In the event that any of the provisions of this Section 5 should

policy matters relating to finance, personnel, management and operations.
Therefore, in order to protect the Employer's and Company's confidential
information and to protect other employees who depend on the Employer and
Company for regular employment, the Executive agrees that he will not in any way
utilize any of said confidential information except in connection with his
employment by the Employer, and except in connection with the business of the
Employer and Company he will not copy, reproduce or take with him the original
or any copies of said confidential information and will not disclose any of said
confidential information to anyone.

     7. TERMINATION.
        ----------- 

        (a) Death or Disability. If the Executive should become physically or
mentally disabled and unable to perform his duties hereunder for a continuous
period in excess of ninety (90) days (in the reasonable opinion of the
Committee), or if the Executive should die while an employee of the Employer,
this Agreement and Executive's employment with the Employer shall immediately
terminate.

        (b) Termination by the Employer for Cause. The following events shall

this Agreement prior to the expiration of the Term: (i) the commission of fraud,
embezzlement or theft by the Executive in connection with the Executive's
duties; (ii) the intentional wrongful damage to property of the

confidential information of the Company, the Employer and/or their Affiliates;

Termination for cause pursuant to this Subsection, all of the obligations of the

Executive. In the event that there occurs without the written consent of the
Executive:

        (i)   a change in the Executive's duties or responsibilities, or a
              change in the Executive's reporting relationships, either of which

              the Executive's duties and responsibilities;

        (ii)  a reduction in the Executive's then current annual base salary
              (other than as part of reductions in annual base salary affecting
              the Employer's officers generally);

        (iii) a reduction in the level of benefits available or awarded under
              employee and officer benefit plans and programs, including, but
              not limited to annual and long-term incentive and stock-based
              plans and programs (other than as part of reductions in such
              benefit plans or programs affecting the Employer's officers
              generally); or

        (iv)  a relocation of Executive's primary employment location to a
              location which is more than 50 miles from his current location

then Executive may deliver written notice of termination to the Company within
three months of such event (which shall be effective even if such three months
expire after the end of the Term). In either case and subject to the execution
and delivery by Executive to the Company of the release described in Section 9
hereof, the Company shall provide Executive with severance compensation and
benefits as follows:

     monthly over a period of months equal to the number of months of severance
     pay provided for by this subsection (u), (such period of payment to be
     referred to as the "Severance Period");

                                       4
<PAGE>
 
     (v) with respect to any participation rights in the Company's annual or
     long-term incentive plans which have been awarded to Executive prior to the
     end of the Term, Executive shall be entitled to receive a prorated award
     under any such plan, payable if and when awards are paid to other similarly
     positioned officers of the Employer, such proration to be determined by
     dividing the number of whole or partial months the Executive is employed
     during the incentive compensation performance period by the total number of
     months in the incentive compensation performance period;

     (w) with respect to the Executive's stock options, the Company will
     recommend to the Compensation and Stock Option Committee of the Board of
     Directors of the Company that the exercisability of the Executive's
     outstanding stock options be accelerated, such options shall remain
     exercisable during the Severance Period (unless they shall expire earlier
     by their terms) and such options shall otherwise be treated in accordance
     with the terms of their respective grants;

     (x) the Executive's medical, dental and vision Benefits shall be continued
     on the same basis as offered to active salaried employees for the Severance
     Period or until such earlier time as the Executive becomes employed and

     continuation coverage under COBRA shall commence at the end of the
     Severance Period;

     (y) credit for vesting and benefit service under the Company's Supplemental
     Executive Retirement Plan shall be provided to Executive for the Severance
     Period; and

     (z) all other Benefits shall be paid or continued only to the extent the
     terms thereof provide for payment or continuation following the termination
     of employment.

The foregoing shall be in lieu of all salary, bonuses or incentive or
performance based compensation for the remainder of the Term. If Executive
should die during the Severance Period, any remaining severance payments shall
be made to Executive's surviving spouse or, if none, to his estate.

        (d) Voluntary Termination. If during the Term the Executive should
voluntarily terminate his employment with the Employer for any reason, including
retirement, other than as described in Subsection 7(c) hereof, the obligations
of the Employer and the Company under this Agreement shall terminate forthwith,
other than obligations to (i) pay the Executive's base salary to the date of
termination, (ii) pay all incentive compensation earned by the Executive for
performance periods which are completed prior to the date of termination, at
such times and on the same basis amounts as such incentive compensation becomes
payable to other executives of the Employer and (iii) pay or make available to
the Executive all Benefits which by their terms or under applicable law survive
the voluntary termination of the Executive's employment; and the Executive shall
remain bound by his non-disclosure, non-solicitation and non-competition
covenants set forth in Sections 5 and 6 hereof. The exercisability of the
Executive's outstanding stock options shall be treated in accordance with the
terms of their

                                       5
<PAGE>
 
respective grants or awards, except that in the case of retirement on or after

Committee of the Board of Directors of the Company that the exercisability of
Executive's outstanding stock options be accelerated.

                              - - - - - - - - - - 

     WHEREAS, the Executive has previously served and is serving as Area

employment.

     NOW, THEREFORE, for and in consideration of the premises and the mutual
covenants contained herein, the parties agree as follows:

     1.   EMPLOYMENT.  The Company or its applicable subsidiary (hereinafter the
"Employer") shall continue to employ the Executive as an employee at will upon

     2.   TERM.  Subject only to the provisions hereof set forth in Section 7,
the term of this Agreement (herein the "Term") shall be for a period beginning
on the date hereof and ending on March 10, 1999. Subject to the provisions of
Section 7 hereof, and unless a party gives 30 days' prior written notice to the

which birthday this Agreement shall terminate unless earlier terminated in
accordance with the terms hereof.

     3.   COMPENSATION.  During the Term, the Executive's salary shall be
payable at intervals not less often than semi-monthly. The Executive's salary
shall be established by either the Compensation and Stock Option Committee of
the Board of Directors of the Company (subject to approval by the full Board)
or, in the event Executive is not among the Company officers whose compensation
is subject to review by the Compensation and Stock Option Committee of the
Board, by the Executive Committee of the Company (the applicable committee being
referred to herein as the "Committee") and all adjustments thereto and all
aspects of the Executive's incentive or performance compensation shall be
established by the Committee in its sole discretion. In the event there is no
Committee in existence at any time, the term Committee shall be deemed to refer
to the Chief Executive Officer of the Company. During the Term, the Executive
shall also receive such benefits and perquisites (the "Benefits") which are made
available to similarly positioned executives of the Employer including, without
limitation, incentive compensation, loans, awards, insurance, stock options,
stock purchase plans, benefits from qualified plans or non-qualified plans or
other benefit plans now or hereafter existing which are adopted by the Employer
for the benefit of its employees generally and for the benefit of the Employer's
officers, all such Benefits to be provided in such amounts as may be determined
from time to time by the Committee in its discretion.

     4.   EXTENT OF SERVICE.  During the Term, the Executive shall devote his
full time, attention and energy to the business of the Employer and the
Executive shall not be engaged in any other business activity pursued for gain,
profit or other pecuniary advantage which activity interferes with the
Executive's duties and responsibilities provided for herein.

     5.   NON-COMPETITION AND NON-SOLICITATION.  Executive agrees that:

          (a) During the Term and for a period of one year thereafter or during
any Severance Period, if longer (the "Restricted Period"), Executive agrees that
he will not (without the written consent of the Chairman of the Board) engage
directly or indirectly in any business within the United States (financially as
an investor or lender or as an employee, director, officer, partner, independent
contractor, consultant or owner or in any other capacity calling for the
rendition of personal services or acts of management, operation or control)
which is directly competitive with the business at any time during the
Restricted Period conducted by the Company or any of its subsidiaries or
Affiliates as defined below.  Notwithstanding the foregoing, Executive shall be
entitled to own securities of any corporation conducting a business competitive
with the business of the Company or any of its subsidiaries or Affiliates so
long as the securities of such corporation are listed on a national securities
exchange and the securities owned directly or indirectly by Executive do not
represent more than two percent (2%) of any class of the outstanding securities
of such company.

          (b) During the Restricted Period, in addition to the obligations
pursuant to Subsection 5(a), Executive agrees that neither he nor any business
in which he engages directly or indirectly will (i) directly or indirectly
induce any customers of the Company or of corporations or 

                                       2
<PAGE>
 
businesses which directly or indirectly control or are controlled by or under
common control with the Company ("Affiliates") to patronize any business similar
to that of the Company, (ii) canvass, solicit or accept any similar business
from any customer of the Company or any Affiliates, (iii) directly or indirectly
request or advise any customer of the Company or Affiliates to withdraw, curtail
or cancel such customer's business with the Company or Affiliates, (iv) directly
or indirectly disclose to any other person, firm or corporation the names or
addresses of any of the customers of the Company or Affiliates, or (v) compete
with the Company or Affiliates in acquiring or merging with any other business
or acquiring the assets of such other business.

          (c) During the Restricted Period, in addition to the obligations
pursuant to Subsections 5(a) and 5(b), Executive agrees that neither he nor any
business in which he engages directly or indirectly will (i) hire or attempt to
hire any employee of the Company or its Affiliates nor (ii) directly or
indirectly encourage any employee of the Company or its Affiliates to terminate
employment with the Company or its Affiliates.  Notwithstanding the foregoing,
it shall not be deemed a violation of this subsection if a business which
employs Executive hires or attempts to hire an employee of the Affiliates and
Executive has no knowledge of, control over or involvement with such
solicitation.

          (d) In the event that any of the provisions of this Section 5 should
ever be deemed to exceed the time, geographic or occupational limitations
permitted by applicable laws, then such provisions shall be and are hereby
reformed to the maximum time, geographic or occupational limitations permitted
by law.

     6.   CONFIDENTIAL INFORMATION.  The Executive acknowledges that in his
employment he is or will be making use of, acquiring or adding to the Employer's
and Company's confidential information which includes, but is not limited to,
memoranda and other materials or records of a proprietary nature and records and
policy matters relating to finance, personnel, management and operations.
Therefore, in order to protect the Employer's and Company's confidential
information and to protect other employees who depend on the Employer and
Company for regular employment, the Executive agrees that he will not in any way
utilize any of said confidential information except in connection with his
employment by the Employer, and except in connection with the business of the
Employer and Company he will not copy, reproduce or take with him the original
or any copies of said confidential information and will not disclose any of said
confidential information to anyone.

     7.   TERMINATION.

          (a) Death or Disability.  If the Executive should become physically
or mentally disabled and unable to perform his duties hereunder for a continuous
period in excess of ninety (90) days (in the reasonable opinion of the
Committee), or if the Executive should die while an employee of the Employer,
this Agreement and Executive's employment with the Employer shall immediately
terminate.

<PAGE>

          (b) Termination by the Employer for Cause.  The following events shall
create in the Employer a right to terminate the Executive's employment under
this Agreement prior to the expiration of the Term: (i) the commission of fraud,
embezzlement or theft by the Executive in connection with the Executive's
duties; (ii) the intentional wrongful damage to property of the Company, the
Employer and/or their Affiliates by the Executive; (iii) the intentional
wrongful disclosure by the Executive of any secret process or confidential
information of the Company, the Employer and/or their Affiliates; or (iv) the
violation of the Executive's non-disclosure, non-solicitation and non-
competition covenants set forth in Sections 5 and 6.  In the event of such a
Termination for cause pursuant to this Subsection, all of the obligations of the
Employer and the Company under this Agreement shall immediately terminate.

          (c) Other Termination by Employer. In the event the Employer shall
elect to terminate Executive's employment for any reason other than those
specified in Subsection 7(a) or 7(b), it shall provide written notice of such
termination to Executive. In the event that there occurs without the written
consent of the Executive:

          (i)    a change in the Executive's duties or responsibilities, or a
                 change in the Executive's reporting relationships, either of
                 which results in or reflects a diminution of the scope or
                 importance of the Executive's duties and responsibilities;

          (ii)   a reduction in the Executive's then current annual base salary
                 (other than as part of reductions in annual base salary
                 affecting the Employer's officers generally);

          (iii)  a reduction in the level of benefits available or awarded under
                 employee and officer benefit plans and programs, including, but
                 not limited to annual and long-term incentive and stock-based
                 plans and programs (other than as part of reductions in such
                 benefit plans or programs affecting the Employer's officers
                 generally);

          (iv)   a relocation of Executive's primary employment location to a
                 location which is more than 50 miles from his current location;
                 or

          (v)    the Company terminates the automatic renewal provision of this
                 Agreement by providing Executive with 30 days' prior written
                 notice as provided in Section 2 hereof

then Executive may deliver written notice of termination of his employment to
the Company within three months of such event (which notice shall be effective
even if such three months expire after the end of the Term). In either case and
subject to the execution and delivery by Executive to the Company of the release
described in Section 9 hereof, the Company shall provide Executive with
severance compensation and benefits as follows:

                                       4
<PAGE>
 
     (t) Executive shall receive an amount equal to his then current base salary
     for two years, payable at intervals not less frequently than monthly over a
     period of two years following the end of the Term (such period of payment
     to be referred to herein as the "Severance Period");

     (u) with respect to any participation rights in the Company's annual or
     long-term incentive plans which have been awarded to Executive prior to the
     end of the Term, Executive shall be entitled to receive a prorated award
     under any such plan, payable if and when awards are paid to other similarly
     positioned officers of the Employer, such proration to be determined by
     dividing the number of whole or partial months the Executive is employed
     during the incentive compensation performance period by the total number of
     months in the incentive compensation performance period;

     (v) with respect to Executive's stock options, the Company will recommend
     to the Compensation and Stock Option Committee of the Board of Directors of
     the Company that the exercisability of Executive's outstanding stock
     options be accelerated, such options shall remain exercisable during the
     Severance Period (unless they shall expire earlier by their terms) and such
     options shall otherwise be treated in accordance with the terms of their
     respective grants;

     (w) the Executive's restricted stock shall be treated in accordance with
     the terms of the Restricted Stock Award Certificate applicable thereto;

     (x) the Executive's medical, dental and vision Benefits shall be continued
     on the same basis as offered to active salaried employees for the Severance
     Period or until such earlier time as the Executive becomes employed and
     eligible for such benefits under a plan of the new employer, and
     continuation coverage under COBRA shall commence at the end of the
     Severance Period; and

     (y) credit for vesting and benefit service under the Company's Supplemental
     Executive Retirement Plan shall be provided to Executive for the Severance
     Period; and

     (z) all other Benefits shall be paid or continued only to the extent the
     terms thereof provide for payment or continuation following the termination
     of employment.

The foregoing shall be in lieu of all salary, bonuses or incentive or
performance based compensation for the remainder of the Term.  If Executive
should die during the Severance Period, any remaining severance payments shall
be made to Executive's surviving spouse or, if none, to his estate.

          (d)  Voluntary Termination.  If during the Term the Executive should
voluntarily terminate his employment with the Employer for any reason, including
retirement, other than as described in Subsection 7(c) hereof, the obligations
of the Employer and the Company under this Agreement shall terminate forthwith,
other than obligations to (i) pay the 

                                       5
<PAGE>
 
Executive's base salary to the date of voluntary termination, (ii) pay all
incentive compensation earned by the Executive for performance periods which are
completed prior to the date of voluntary termination, at such times and on the
same basis amounts as such incentive compensation becomes payable to other
executives of the Employer and (iii) pay or make available to the Executive all
Benefits which by their terms or under applicable law survive the voluntary
termination of the Executive's employment; and the Executive shall remain bound
by his non-disclosure, non-solicitation and non-competition covenants set forth
in Sections 5 and 6 hereof. The exercisability of the Executive's outstanding
stock options and the vesting of the Executive's restricted stock shall be
treated in accordance with the terms of their respective grants or awards,
except that in the case of retirement on or after age 62, the Company will
recommend to the Compensation and Stock Option Committee of the Board of
Directors of the Company that the exercisability of Executive's outstanding
stock options be accelerated.

notice provided for in Subsection 7(c), that would extend the time period during
which the base salary is to be paid under Subsection 7(c) for one additional
year.  The total amount of base salary that is to be paid under Subsection 7(c)
will not be affected by this election.  If such election is made, the term
"Severance Period" will be deemed to refer to such extended payment period.

     9.  GENERAL RELEASE AND COOPERATION AGREEMENT.  Notwithstanding anything in
Subsection 7(c) to the contrary and in consideration therefor, severance
benefits thereunder shall only become payable by the Company if the Executive
executes and delivers to the Company a General Release and Cooperation Agreement

WMI                         WASTE MANAGEMENT, INC.
                          RESTRICTED STOCK AGREEMENT
                          --------------------------


     This Restricted Stock Agreement (the "Agreement"), made this ___ of
___________, _______, by and between WASTE MANAGEMENT, INC., a Delaware
corporation (hereinafter called the "Corporation"), and _____________, a
director of the Corporation (hereinafter called the "Director");

                                 WITNESSETH:

     WHEREAS, the Board of Directors of the Corporation has determined it to be
in the best interests of the Corporation to grant restricted stock awards to its
directors in order to provide such directors with an additional stake in the
results of the Corporation, to more closely align their interests with those of
the Corporation's stockholders and to encourage them to continue serving the
Corporation; and

     WHEREAS, the Board of Directors has made such an award to the Director and
the Director has agreed to the terms and conditions thereof as set forth in this
Agreement;

     NOW, THEREFORE, for and in consideration of the mutual covenants and
agreements of the parties hereto, it is agreed as follows:

     1.   Grant.  Pursuant to this Agreement, the Corporation will from time to
time grant to the Director and the Director will accept certain shares (the
"Restricted Shares") of common stock, $1.00 par value, of the Corporation (the
"Common Stock"), subject to the restrictions, terms and conditions set forth in
this Agreement.

     2.   Restrictions.  During the Restricted Period described in Paragraph 4
below, the Director may not, directly or indirectly, by operation of law or
otherwise, voluntarily or involuntarily, anticipate, alienate, attach, sell,
assign, pledge, encumber, charge or otherwise transfer any of the Restricted
Shares (the "Restrictions").  Upon the expiration of the Restricted Period, all
Restrictions shall lapse.

     3.   Award Date.  The effective date of a grant of the Restricted Shares to
the Director (the "Award Date") shall be set forth in an Award Certificate
delivered to the Director at the time of the Grant.

     4.   Restricted Period.  The Restricted Period shall commence on the Award
Date and shall expire on the last day of the calendar month during which the
Director's service as a director of the Corporation terminates or, if earlier,
the first to occur of the following dates:

          (a)  the Director's death; or

          (b) the Director's total disability, which shall mean a physical or
     mental condition such that the Director is unable to perform the functions
     required by his or her 
<PAGE>
 
     membership on the Board of Directors as determined by a physician
     acceptable to the Corporation.

     5.   (a)  Effect of Termination of Service and Other Events.  Subject to
the provisions of Section 5(b) hereof, in the event of the termination of the
Director's membership on the Board of Directors of the Corporation, and all
other corporations, partnerships, joint ventures, affiliates, or other entities
in which the Corporation is the direct or indirect beneficial owner of not less
than 20% of all issued and outstanding equity interests, prior to the Vesting
Date (as defined below), 100% of the Restricted Shares granted in such grant
shall be forfeited. In the event of the termination of the Director's membership
on the Board of Directors of the Corporation after the Vesting Date of such
grant, 100% of the Restricted Shares granted in such grant shall be "Vested
Restricted Shares"; provided, however, that Vested Restricted Shares shall
continue to be subject to the Restrictions until the expiration of the
Restricted Period pursuant to Paragraph 4 above.  However, and notwithstanding
the foregoing, to the extent provided in Paragraph 5(b) all Restricted Shares
shall be considered Vested Restricted Shares.  The Vesting Date shall be the
first to occur of (i) the six month anniversary of the Award Date, or (ii) the
date of the Corporation's annual meeting of stockholders next following the
Award Date.

          (b) Accelerated Vesting.  Upon the occurrence of any event described
     in this Paragraph 5(b), the forfeited percentage shall be zero and 100% of
     the Restricted Shares shall become Vested Restricted Shares:

               (i) the date of a Change in Control of the Corporation; or

               (ii) the date of any event described in Paragraph 4(a) or (b).

          (c) Change in Control. For purposes of this Agreement, "Change in
     Control" shall mean:

               (i) The Corporation is merged or consolidated or reorganized into
          or with another corporation or other legal person (an "Acquiror") and
          as a result of such merger, consolidation or reorganization less than
          75% of the outstanding voting securities or other capital interests of
          the surviving, resulting or acquiring corporation or other legal
          person are owned in the aggregate by the stockholders of the
          Corporation, directly or indirectly, immediately prior to such merger,
          consolidation or reorganization, other than by the Acquiror or any
          corporation or other legal person controlling, controlled by or under
          common control with the Acquiror;

               (ii) The Corporation sells all or substantially all of its
          business and/or assets to an Acquiror, of which less than 75% of the
          outstanding voting securities or other capital interests are owned in
          the aggregate by the stockholders of the Corporation, directly or
          indirectly, immediately prior to such sale, other than by any
          corporation or other legal person controlling, controlled by or under
          common control with the Acquiror;

                                       2
<PAGE>
 
               (iii) There is a report filed on Schedule 13D or Schedule 14D-1
          (or any successor schedule, form or report), each as promulgated
          pursuant to the Exchange Act, disclosing that any person or group (as
          the terms "person" and "group" are used in Section 13(d)(3) or Section
          14(d)(2) of the Exchange Act and the rules and regulations promulgated
          thereunder) has become the beneficial owner (as the term "beneficial
          owner" is defined under Rule 13d-3 or any successor rule or regulation
          promulgated under the Exchange Act) of 20% or more of the issued and
          outstanding shares of voting securities of Corporation; or

               (iv) During any period of two consecutive years, individuals who
          at the beginning of any such period constitute the directors of the
          Corporation cease for any reason to constitute at least a majority
          thereof unless the election, or the nomination for election by the
          Corporation's stockholders, of each new director of the Corporation
          was approved by a vote of at least two-thirds of such directors of the
          Corporation then still in office who were directors of the Corporation
          at the beginning of any such period.

     6.   Custody of Restricted Shares; Tax Withholding; Voting; Dividends.
          -----------------------------------------------------------------

          (a) Certificates Representing Restricted Shares.  The Restricted
     Shares will be registered in the name of the Director and the certificates,
     if any, evidencing such shares shall bear an appropriate legend referring
     to the terms, conditions and restrictions applicable to the Restricted
     Shares.  Shares may be issued without certificates, in the Corporation's
     discretion, to the extent permitted from time to time by Corporation
     procedures.  All certificates representing Restricted Shares shall be
     retained by the Corporation, together with a stock power executed by the
     Director in proper form for transfer into the Corporation's name of all
     certificates representing Restricted Shares which are forfeited to the
     Corporation in accordance with Paragraph 5.

          (b) Delivery to the Director; Tax Withholding.  Certificates
     representing Restricted Shares with respect to which all Restrictions have
     lapsed shall be delivered by the Corporation to the Director (or in the
     event of the Director's death, to the Director's designated beneficiary or,
     if no beneficiary has been designated, to the Director's estate) promptly
     after the expiration of the Restricted Period.

          (c) Voting Rights.  The Director will have all rights of a stockholder
     with respect to voting of the Restricted Shares.

          (d) Dividends and Other Distributions.  Directors to whom Restricted
     Shares have been granted hereunder shall be entitled to all dividends and
     other distributions paid with respect thereto during the Restricted Period,
     provided that if such dividend or other distribution is in the form of
     additional shares of Common Stock, such additional shares shall be deemed
     to be part of the Restricted Shares (and, as such, shall be held subject to
     the Restrictions hereunder), subject to a vesting period equal to the
     remaining vesting period, if any, of the Restricted Shares with respect to
     which they were distributed.  At the Director's irrevocable election, (i)
     cash dividends paid with respect to the Restricted Shares shall be, or

                                       3

<PAGE>
 
     shall be deemed to be, reinvested in additional Common Stock and (ii) other
     distributions in respect of Restricted Shares shall be held by the Company
     on behalf of such Director, and shall be deemed to be part of the
     Restricted Shares to which such dividends and other distributions relate
     and, as such, shall be held subject to the Restrictions hereunder.  The
     Director may revoke such election only with respect to dividends and other
     distributions not yet declared.

     7.   Source of Common Stock.  All Restricted Shares granted under this
Agreement will be issued from treasury shares held by the Corporation.

     8.   Entire Understanding.  This Agreement constitutes the entire
understanding between the parties relating to the matters described herein and
supersedes and cancels all prior written and oral understandings and agreements
with respect to such matters.

     9.   Binding Effect.  This Agreement shall be binding upon and inure to the
benefit of the Director's executors, administrators, legal representatives,
heirs and legatees and the successors and assigns of the Corporation.

     10.  Partial Invalidity.  The various provisions of this Agreement are
intended to be severable and to constitute independent and distinct binding
obligations.  Should any provision of this Agreement be determined to be void
and unenforceable, in whole or in part, it shall not be deemed to affect or
impair the validity of any other provision or part thereof, and such provision
or part thereof shall be deemed modified to the extent required to permit
enforcement.  Without limiting the generality of the foregoing, if the scope of
any provision contained in this Agreement is too broad to permit enforcement to
its full extent, but may be made enforceable by limitations thereon, such
provision shall be enforced to the maximum extent permitted by law, and the
Director hereby agrees that such scope may be judicially modified accordingly.

     11.  Waiver.  The waiver of any party hereto of a breach of any provision
of this Agreement by any other party shall not operate or be construed as a
waiver of any subsequent breach.

     12.  Governing Law.  This Agreement shall be governed by, and interpreted,
construed and enforced in accordance with, the laws of the State of Illinois.

                                       4

                                  ARTICLE II

                       PURCHASE AND SALE OF RECEIVABLES

          2.1  Purchase and Sale of Receivables.  (a)  Each of the Sellers 
               --------------------------------   
hereby sells, transfers, assigns and conveys, without recourse (except as
expressly provided herein), to the Purchaser, all its present and future right,
title and interest in, to and under:

               (i)    all Receivables existing at the opening of business on the
     Effective Date with respect to such Seller and all such Receivables
     thereafter arising from time to time until but not including the date an
     Early Termination occurs with respect to such Seller;

               (ii)   the Related Property in respect of such Receivables;

               (iii)  all Collections in respect of such Receivables;

               (iv)   all rights (including rescission, replevin or reclamation,
     but none of the obligations) relating to such Receivables or arising
     therefrom;

               (v)    all proceeds of or payments in respect of any and all of
     the foregoing clauses (i) through (iv).

Such property described in the foregoing clauses (i) through (v) shall be
referred to herein as the "Receivable Assets."  Subject to the terms and
conditions set forth herein, the Purchaser hereby agrees to purchase the
Receivable Assets of each Seller.

          The term "Effective Date" when used with respect to any Seller shall
mean the date specified as the "Effective Date" for such Seller on Schedule 1
hereto or in the notice delivered by WMI pursuant to the following sentence.
WMI may at any time, and from time to time after the Commencement Date, by
delivery to the Purchaser (with a copy to the Administrative Agent) of written
notice 
<PAGE>
 
                                                                               3

substantially in the form of Exhibit C irrevocably designate with respect to any
Seller the date that shall be the "Effective Date" with respect to such Seller.

          (b)  On the Effective Date with respect to a Seller and on the date of
creation of each newly created Receivable (but only so long as no Early
Termination shall have occurred and be continuing with respect to such Seller),
all of such Seller's right, title and interest in and to (i) in the case of the
Effective Date, all then existing Receivables and all other Receivable Assets in
respect of such Receivables and (ii) in the case of each such date of creation,
all such newly created Receivables and all other Receivable Assets in respect of
such Receivables shall be considered to be part of the assets that have been
sold, transferred, assigned, set over and otherwise conveyed to the Purchaser
pursuant to paragraph (a) above without any further action by any Seller or any
other Person. Anything herein to the contrary notwithstanding, to the extent any
Seller shall not have received payment from the Purchaser of the Purchase Price
for any Receivable and other related Receivable Assets in accordance with the
terms of subsection 2.3, such Receivable and Receivable Assets shall, upon
receipt by the Purchaser and the Administrative Agent of notice from such Seller
of such failure to receive payment, immediately and automatically be sold,
assigned, transferred and reconveyed by the Purchaser to such Seller without any
further action by the Purchaser or any other Person.

          (c)  The parties to this Agreement intend that, for accounting and
commercial purposes, the transactions contemplated by this subsection 2.1 hereby
shall be, and shall be treated as, a purchase by the Purchaser and a sale by
each Seller of the Purchased Receivables and other Receivable Assets and not a
lending transaction.  All sales of Receivables and other Receivable Assets by
each Seller hereunder shall be without recourse to, or representation or
warranty of any kind (express or implied) by, such Seller, except as otherwise
specifically provided herein.  The foregoing sale, assignment, transfer and
conveyance does not constitute and is not intended to result in the creation or
assumption by the Purchaser of any obligation of any Seller or any other Person
in connection with the Receivables, the other Receivable Assets or any agreement
or instrument relating thereto, including any obligation to any Obligor.

          (d)  In connection with the foregoing conveyances, each Seller agrees
to record and file, or cause to be recorded and filed, at its own expense,
financing statements (and continuation statements with respect to such financing
statements when applicable) with respect to the Receivables and the Receivable
Assets now existing and hereafter acquired pursuant to this Agreement by the
Purchaser from each Seller and in each case meeting the requirements of
applicable law in such manner and in such jurisdictions as are necessary to
perfect and maintain perfection of the Purchaser's purchase of such Receivables
and any other Receivable Assets and to deliver to the Administrative Agent no
later than 10 days after the Commencement Date (i) where available, a file-
stamped copy or certified statement of such financing statement or other
evidence of such filing and (ii) otherwise, a photocopy, certified by a
Responsible Officer to be a true and correct 
<PAGE>
 
                                                                               4

copy, of each such financing statement or other filing made no later than 10
days after the Commencement Date.

          (e)  In connection with the foregoing sales, transfers, assignments
and conveyances, each Seller agrees at its own expense, no later than 30 days
after the Effective Date with respect to such Seller that it will, as agent of
the Purchaser indicate or cause to be indicated on the computer files (but not
on individual invoices or individual collection files) relating to the
Receivables of such Seller (by means of a general legend that will automatically
appear at or near the beginning of any screen, list or print-out of such
Receivables) that, unless otherwise specifically identified on such screen, list
or print-out as a receivable not so sold, transferred, assigned and conveyed,
all Receivables included in such screen, list or print-out and all other
Receivable Assets (and any other similar related property) have been sold,
transferred, assigned and conveyed to the Purchaser in accordance with this
Agreement.

          (f)  As further confirmation of the sale of the Receivables, it is
understood and agreed that the Purchaser shall have the following rights:

               (i)    the Purchaser shall have the right at any time to notify,
     or require that any Seller at its own expense notify, the respective
     Obligors of the Purchaser's ownership of the Purchased Receivables and
     other Receivable Assets and may direct that payment of all amounts due or
     to become due under the Purchased Receivables be made directly to the
     Purchaser or its designee;

               (ii)   the Purchaser shall have the right to (A) sue for
     collection on any Purchased Receivables or (B) sell any Purchased
     Receivables to any Person for a price that is acceptable to the Purchaser;

               (iii)  each Seller shall, upon the Purchaser's written request
     and at such Seller's expense, (A) assemble all of such Seller's documents,
     instruments and other records (including credit files and computer tapes or
     disks) that (1) evidence or will evidence or record Receivables sold by
     such Seller and (2) are otherwise necessary or desirable to effect
     Collections of such Purchased Receivables (collectively, the "Documents")
     and (B) deliver the Documents to the Purchaser or its designee at a place
     designated by the Purchaser.  In recognition of such Seller's need to have
     access to any Documents which may be transferred to the Purchaser
     hereunder, whether as a result of its continuing business relationship with
     any Obligor for Receivables purchased hereunder, the Purchaser hereby
     grants to each Seller an irrevocable license to access the Documents
     transferred by such Seller to the Purchaser and to access any such
     transferred computer software in connection with any activity arising in
     the ordinary course of such Seller's business; provided, that such Seller
                                                    --------                  
     shall not disrupt or otherwise interfere with the Purchaser's use of and
     access to the Documents and its computer software during such license
     period;
<PAGE>
 
                                                                               5

               (iv)   each Seller hereby grants to the Purchaser and the
     Administrative Agent an irrevocable power of attorney (coupled with an
     interest) to take any and all steps in such Seller's name necessary or
     desirable, in the reasonable opinion of the Purchaser, to collect all
     amounts due under the Purchased Receivables, including, without limitation,
     enforcing the Purchased Receivables and exercising all rights and remedies
     in respect thereof and endorsing such Seller's name on checks and other
     instruments representing Collections; and

               (v)    promptly upon written request of the Purchaser, after the
     occurrence of a Servicer Event of Default, each Seller will (A) deliver to
     the Purchaser all licenses, rights, computer programs, related material,
     computer tapes, disks, cassettes and data necessary for the immediate
     collection of the Purchased Receivables by the Purchaser, with or without
     the participation of such Seller (excluding software licenses which by
     their terms are not permitted to be so delivered; provided, that such
                                                       --------           
     Seller shall use reasonable efforts to obtain the consent of the relevant
     licensor to such delivery) and (B) make such arrangements with respect to
     the collection of the Purchased Receivables as may be reasonably required
     by the Purchaser.

          2.2  Purchase Price.  The amount payable by the Company to a Seller
               --------------                                                
(the "Purchase Price") for Receivables and Receivable Assets existing on the
Effective Date with respect to such Seller and for newly created Receivables and
Receivable Assets on any Payment Date under this Agreement shall be equal to the
product of (a) the aggregate outstanding Principal Amount of such Receivables as
set forth in the applicable Daily Report and (b) the Discounted Percentage for
such Payment Date.

          2.3  Payment of Purchase Price.  (a)  Upon fulfillment of the
               -------------------------                               
conditions set forth in Article III, the Purchase Price for Receivables and
other Receivable Assets shall be paid or provided for in the manner provided
below on each day for which a Daily Report is prepared and delivered to the
Company (each such day, a "Payment Date").  Each Seller hereby appoints the
Master Servicer as its agent to receive payment of the Purchase Price for
Receivables sold by it to the Company and hereby authorizes the Company to make
all payments due to such Seller directly to, or as directed by, the Master
Servicer.  The Master Servicer hereby accepts and agrees to such appointment and
to the provisions of subsection 2.3(d).

          (b)  The Purchase Price for Receivables and Receivable Assets with
respect thereto purchased by the Company on any Payment Date shall be paid by
the Company on such Payment Date as follows:

               (i)    by netting the amount of any Seller Adjustment Payments or
     Seller Repurchase Payments pursuant to subsection 2.5 or 2.6 against such
     Purchase Price;

                                                                               6

               (ii)   to the extent available for such purpose, in cash from
     Collections;

               (iii)  to the extent available for such purpose, in cash from
     the net proceeds of the sale of an interest in such Purchased Receivables
     by the Company to other Persons;

               (iv)   at the option of the Company, by means of an addition to
     the principal amount of the Subordinated Note, as appropriate in accordance
     with this subsection, in an aggregate amount equal to the remaining portion
     of the Purchase Price; provided, that on the Commencement Date, amounts
                            --------                                        
     available pursuant to clause (v) shall be used prior to making any payment
     of the Purchase Price by means of an addition to the Subordinated Note;
     provided, however, that the Company may pay by means of additions to the
     --------  -------                                                       
     principal amount of the Subordinated Note only if, at the time of such
     payment and after giving effect thereto, the fair market value of its
     assets, after giving effect for this purpose to any Adjustments with
     respect to the Purchased Receivables or any participation interest therein
     sold to the Participants under the Receivables Transfer Agreement, is
     greater than the sum of (i) the amount of its liabilities, including its
     liabilities on the Subordinated Note and all fees payable under the
     Receivables Transfer Agreement, and (ii) the Minimum Equity Amount.  Any
     such addition to the principal amount of the Subordinated Note shall be
     allocated among the Sellers by the Master Servicer. The Master Servicer may
     evidence such payments by means of additions to the principal amount of the
     Subordinated Note by recording the date and amount thereof on the books and
     records of the Master Servicer or the Sellers or on the grid attached to
     the Subordinated Note; provided, that the failure to make any such
                            --------
     recordation or any error in such grid shall not adversely affect any
     Seller's rights; and

               (v)    in cash from the proceeds of capital contributed by WMI to
     the Company in respect of its equity interest in the Company.

          (c)  The Master Servicer may allocate among the Sellers the payment of
the Purchase Price for Receivables and any amounts netted therefrom pursuant to
subsection 2.3(b)(i).  The Company shall be entitled to pay all amounts in
respect of the Purchase Price of Receivables to an account of the Master
Servicer without regard to whether or how such payments are allocated by the
Master Servicer to the Sellers.  Each Seller agrees that payment to the Master
Servicer of the Purchase Price shall constitute payment to such Seller.  All
payments under this Agreement (i) shall be made on the date specified therefor
in Dollars in same day funds or by check, as the Master Servicer shall elect,
(ii) shall be made not later than 3:00 p.m (New York City time) on the date
specified therefor and (iii) shall be made (x) if to any Seller, to the bank
account for such Seller designated in writing by the Master Servicer to the
Company and (y) if to the Master Servicer, to the bank account designated in
writing by the Master Servicer to the Company.

          (d)  Whenever any payment to be made under this Agreement shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day.  Amounts not paid when due in accordance
with the terms of this Agreement shall bear interest at a rate equal at all
times to the ABR plus 2%, payable on demand.
                 ----                       

          2.4  No Repurchase.  Except to the extent expressly set forth herein,
               -------------                                                   
no Seller shall have any right or obligation under this Agreement, by
implication or otherwise, to repurchase from the Company any Purchased
Receivables or other Receivable Assets or to rescind or otherwise retroactively
effect any purchase of any Purchased Receivables or Receivable Assets after the
Payment Date relating thereto.

          2.5  Rebates, Adjustments, Returns and Reductions; Modifications.
               -----------------------------------------------------------  
From time to time a Seller may make Adjustments to Receivables in accordance
with this subsection 2.5 and subsection 6.2.  Each Seller (with respect to which
its Effective Date has occurred), jointly and severally, agrees to pay to the
Company (regardless of which Seller shall have granted such Adjustment), the
amount of any such Adjustment (a "Seller Adjustment Payment") as follows:  (i)
prior to an Early Termination with respect to all Sellers, the amount of any
such Seller Adjustment Payment shall be paid by (x) effectively netting the
product of such Adjustment and the Discount Percentage then in effect against
the Purchase Price of Receivables created after the grant of such Adjustment in
accordance with subsection 2.3(b)(i) and paying the remainder of such Seller
Adjustment Payment in cash on the first Settlement Date to occur after the grant
of such Adjustment and (y) after an Early Termination with respect to all
Sellers, the amount of any such Seller Adjustment Payment shall be paid in cash
no later than five Business Days after the grant of such Adjustment. An
"Adjustment" shall mean any rebate, administrative fee, discount, credit memo,
refund, non-cash payment or adjustment (including, without limitation, as a
result of the application of any special or other discounts or any
reconciliations) in respect of any Receivable, the amount owing for any returns
or cancellations and the amount of any other reduction of any payment under any
Receivable in each case granted or made by the applicable Seller to the related
Obligor; provided, that an "Adjustment" does not include any Defaulted 
         --------                                       
Receivables. The amount of any Adjustment shall be set forth on the first Daily
Report prepared after the date the Adjustment is first recorded on the computer
records of the Master Servicer or any of its Subsidiaries, which for purposes of
this subsection 2.5 shall constitute the date of "grant" thereof. Each Seller
agrees to promptly record Adjustments in accordance with its historical
practices.

          2.6  Limited Repurchase Obligation.  In the event that any of the
               -----------------------------                               
representations or warranties contained in subsection 4.2 in respect of any
Receivable shall be or have been incorrect in any material respect as of the
date made or deemed made, or any Receivable shall become subject to any MDN
defense, dispute, offset or counterclaim of any kind (other than as expressly
permitted by this Agreement) or any Seller shall breach any covenant contained
in subsection 
<PAGE>
 
                                                                               8

5.2, 5.10, 5.14 5.15 or Article VI with respect to any Receivable (each of the
foregoing events or circumstances, a "Repurchase Event"), such Receivable shall
cease to be an Eligible Receivable on the date on which such Repurchase Event
occurs. In addition, if any Repurchase Event shall occur with respect to any
Receivable, then each Seller (with respect to which its Effective Date has
occurred), jointly and severally, agrees to pay to the Company an amount (the
"Repurchase Amount") in cash equal to the Purchase Price of such Receivable
(whether the Company paid such Purchase Price in cash or otherwise) less
Collections received by the Company in respect of such Receivable, regardless of
which Seller shall have been responsible for such Repurchase Event, such payment
to occur no later than the 30th day after the day such Repurchase Event becomes
known (or should have become known with due diligence) to any Seller (except
that if such day is not a Business Day, such payment shall be made on the
Business Day immediately succeeding such day) unless such Repurchase Event shall
have been cured on or before such day; provided, that, prior to the occurrence 
                                       --------       
of an Early Termination with respect to all Sellers, any such payments to the
Company shall be netted against the Purchase Price of newly created Receivables
in accordance with subsection 2.3(b)(i) to the extent of such Purchase Price and
the remaining amount of such Seller Repurchase Payment due to the Company after
such netting, if any, shall be paid to the Company on such date in cash. Any
payment by any Seller pursuant to this subsection 2.6 is referred to as a
"Seller Repurchase Payment." If, on or prior to such 30th day (or the Business
Day immediately succeeding such 30th day, as applicable), any Seller shall so
reacquire any such Receivable, then the Company shall have no further remedy
against the Sellers in respect of the Repurchase Event with respect to such
reacquired Receivable. Upon a Seller Repurchase Payment, the Company shall
automatically and without further action be deemed to sell, transfer, assign,
set over and otherwise convey to the applicable Seller, without recourse,
representation or warranty, all the right, title and interest of the Company in,
to and under such Receivable and the other Receivable Assets with respect
thereto. The Company shall execute such documents and instruments of transfer or
assignment and take such other actions as shall reasonably be requested by such
Seller to effect the conveyance of such Receivable pursuant to this subsection
2.6.

          2.7  Obligations Unaffected.  The obligations of the Sellers to the
               ----------------------                                        
Company under this Agreement shall not be affected by reason of any invalidity,
illegality or irregularity of any Receivable or any sale of a Receivable.

          2.8  Certain Charges.  Each of the Sellers and the Company agrees that
               ---------------                                                  
late charge revenue, reversals of discounts, other fees and charges and other
similar items, whenever created, accrued in respect of Purchased Receivables
shall be the property of the Company notwithstanding the occurrence of an Early
Termination, and all Collections with respect thereto shall continue to be
allocated and treated as Collections in respect of Purchased Receivables.

          2.9  Certain Allocations.  Each of the Sellers hereby agrees that,
               -------------------                                          
following the occurrence of an Early Termination in respect of any Seller, all

Collections and other proceeds received in respect of Receivables generated by
such Seller shall be applied first, to pay the outstanding Principal Amount of

Purchased Receivables (as of the date of such Early Termination) of the Obligor
to whom such Collections are attributable until such Purchased Receivables are
paid in full and second, to such Seller to pay Receivables of such Obligor not
                 ------                                                       
sold to the Company; provided, however, that notwithstanding the foregoing, if
                     --------  -------                                        
any such Seller can attribute a Collection to a specific Obligor and a specific
Receivable, then such Collection shall be applied to pay such Receivable of such
Obligor.

     required, stockholder action.

          (c)  Enforceability.  Each of this Agreement and the other Transaction
     Documents to which it is a party has been duly executed and delivered by it
     and constitutes a legal, valid and binding obligation of it enforceable
     against it in accordance with its terms, except as enforceability may be
     limited by bankruptcy, insolvency, moratorium, reorganization or other
     similar laws affecting creditors' rights generally and except as
     enforceability may be limited by general principles of equity, regardless
     of whether such enforceability is considered in a proceeding in equity or
     at law.

          (d)  Governmental Approvals; No Conflicts. The execution, delivery and
     performance by it of this Agreement and each of the other Transaction
     Documents to which it is a party, the sale of Receivables by it hereunder
     and the consummation of the other transactions contemplated by any of the

     or other organizational documents of it or any order of any Governmental
     Authority, (c) will not violate or result in a default under any indenture,
     agreement or other instrument binding upon such Seller or its assets, or
     give rise to a right thereunder to require any payment to be made by such
     Seller, and (d) will not result in the creation or imposition of any Lien
     on any asset of such Seller.

          (e)  Capitalization.  All of its Capital Stock is owned directly or
     indirectly by WMI.

          (f)  Litigation; Compliance with Laws.  (1)  Except for the Disclosed
     Matters, as of the Commencement Date, there are no actions, suits or
     proceedings by or before any arbitrator or Governmental Authority pending
     against or, to its knowledge, threatened against or affecting such Seller
     (a) could reasonably be expected, individually or in the aggregate, to
     result in a Material Adverse Effect (other than the Disclosed Matters) or
     (b) that involve this Agreement or the Sale Transactions.

          (2)  Except for the Disclosed Matters and except with respect to any
     other matters that, individually or in the aggregate, could not reasonably
     be expected to result in a Material Adverse Effect, such Seller (i) has not
     failed to comply with any Environmental Law or to obtain, maintain or
     comply with any permit, license or other approval required under any
     Environmental Law, (ii) has not become subject to any Environmental
     Liability, (iii) has 
<PAGE>
 
                                                                              15

     not received notice of any claim with respect to any Environmental
     Liability or (iv) does not know of any basis for any Environmental
     Liability.

               (3)  Since the date of this Agreement, there has been no change
     in the status of the Disclosed Matters that, individually or in the
     aggregate, has resulted in, or materially increased the likelihood of, a
     Material Adverse Effect.

          (g)  Compliance with Laws and Agreements.  It is in compliance with
     all laws, regulations and orders of any Governmental Authority applicable
     to it or its property and all indentures, agreements and other instruments
     binding upon it or its property, except where the failure to do so,
     individually or in the aggregate, could not reasonably be expected to
     result in a Material Adverse Effect.

          (h)  Taxes.  It has timely filed or caused to be filed all Tax returns
     which are required to have been filed and has paid or caused to be paid all
     Taxes required to have been paid by it, except (i) Taxes that are being
     contested in good faith by appropriate proceedings and for which it has set
     aside on its books adequate reserves or (ii) to the extent that the failure
     to do so could not reasonably be expected to result in a Material Adverse
     Effect.

          (i)  Accuracy and Completeness of Information.  It has disclosed to
     the Company all agreements, instruments and corporate or other restrictions
     to which it is subject, and all other matters known to it, that,
     individually or in the aggregate, could reasonably be expected to result in
     a Material Adverse Effect.

          (j)  Employee Benefit Plans.  No ERISA Event has occurred or is
     reasonably expected to occur that, when taken together with all other such
     ERISA Events for which liability is reasonably expected to occur, could
     reasonably be expected to result in a Material Adverse Effect. The present
     value of all accumulated benefit obligations of all underfunded Plans
     (based on the assumptions used for purposes of Statement of Financial
     Accounting Standards No. 87) did not, as of the date of the most recent
     financial statements reflecting such amounts, exceed by more than
     $40,000,000 the fair market value of the assets of all such underfunded
     Plans.

          (k)  Solvency.  The sale of the Receivables by it to the Company has
     not been made in contemplation of the occurrence of any Insolvency Event.
     Both prior to and after giving effect to the transactions occurring on the
     Effective Date or such Closing Date, (i) the fair value of the assets of
     such Seller at a fair valuation will exceed the debts and liabilities,
     subordinated, contingent or otherwise, of such Seller; (ii) the present
     fair salable value of the property of such Seller will be greater than the
<PAGE>
 
                                                                              16

     amount that will be required to pay the probable liability of such Seller
     on its debts and other liabilities, subordinated, contingent or otherwise,
     as such debts and liabilities become absolute and matured; (iii) such
     Seller will be able to pay its debts and liabilities, subordinated,
     contingent or otherwise, as such debts and liabilities become absolute and
     matured; and (iv) such Seller will not have unreasonably small capital with
     which to conduct the business in which it is engaged as such business is
     now conducted and is proposed to be conducted. For all purposes of clauses
     (i) through (iv) above, the amount of contingent liabilities at any time
     shall be computed as the amount that, in the light of all the facts and
     circumstances existing at such time, represents the amount that can
     reasonably be expected to become an actual or matured liability. Such
     Seller does not intend to, nor does it believe that it will, incur debts
     beyond its ability to pay such debts as they mature, taking into account
     the timing of and amounts of cash to be received by it and the timing of
     and amounts of cash to be payable in respect of its debt.

          (k)  Absence of Certain Restrictions.  No indenture, certificate of
     designation for preferred stock, agreement or other instrument to which it
     or any of its Subsidiaries is a party will prohibit or materially restrain,
     or have the effect of prohibiting or materially restraining, or imposing
     materially adverse conditions upon, the sale and assignment of Receivable
     Assets.

          (l)  Indebtedness to Company.  Immediately prior to consummation of
     the transactions contemplated hereby on the Commencement Date, it had no
     outstanding Indebtedness to the Company other than amounts permitted by
     this Agreement.

          (m)  Designated Accounts.  Set forth in Schedule 2 is a complete and
     accurate description as of the Effective Date of each Designated Account
     currently maintained by such Seller.  Such Designated Account will only be
     used for the collection of Receivables and the Designated Bank has received
     standing instructions to transfer at least as often as once each day
     (unless the amount on deposit on such day is less than $5,000) that is a
     Business Day for such Designated Bank and in any event by 1:00 p.m. (New
     York City time) on the Business Day following each such day of deposit, by
     wire transfer of immediately available funds all available funds on deposit
     in such Designated Account to the Concentration Account (either directly or
     indirectly through another Designated Account) along with any remittance
     advisements or payment invoices on deposit therein.

          (n)  Filings.  Upon the making of the filings and the performance of
     the acts described in clause (v) of subsection 3.1 or clause (vi) of
     subsection 3.4, as the case may be, all filings and other acts (including
     but not limited to all filings and other acts necessary or advisable under
     the Uniform Commercial Code of each relevant jurisdiction) shall have been
     made 
<PAGE>
 
                                                                              17

     or performed such that the Company has a first priority perfected ownership
     interest in respect of all Receivables.

          (o)  Offices.  The offices at which each Seller keeps its records
     concerning the Receivables are located at the addresses previously
     disclosed to the Company or have been reported to the Company and the
     Administrative Agent in accordance with the provisions of subsection 5.7 of
     this Agreement.  The chief executive office of such Seller is located at
     the address set forth on Schedule 1 (as such location may be changed from
     time to time in accordance with subsection 5.7 of this Agreement) and is
     the place where the Company is "located" for the purposes of Section 9-
     103(3)(d) of the UCC as in effect in the State of New York.  The state and
     county where the chief executive office of such Seller is "located" for the
     purposes of Section 9-103(3)(d) of the UCC as in effect in the State of New
     York has not changed in the past four months.  The Seller is duly qualified
     to do business in each state set forth opposite its name on Schedule 1
     hereto and is not qualified to do business in any other state.

          (p)  Receivables Documents.  Upon the delivery, if any, by it to the
     Company of licenses, rights, computer programs, related materials, computer
     tapes, disks, cassettes and data relating to the administration of the
     Purchased Receivables pursuant to subsection 2.1(f)(v), the Company shall
     have been furnished with all materials and data necessary to permit
     immediate collection of the Purchased Receivables without the participation
     of any Seller in such collection.

          (q)  Investment Company Act.  It is not an "investment company" as
     defined in, or subject to regulation under, the Investment Company Act of
     1940, as amended.

          (r)  Bulk Sales Act.  No transaction contemplated hereby with respect
     to any Seller requires compliance with, or will be subject to avoidance
     under, any bulk sales act or similar law.

          (s)  Names.  The legal name of each Seller is as set forth on Schedule
     1 to this Agreement.  It has no trade names, fictitious names, assumed
     names or "doing business as" names, which do not include either the words
     "Waste Management" or "Chemical Waste Management".

          (t)  No Purchase Termination Event.  As of the Commencement Date and
     its Effective Date, no Purchase Termination Event or Incipient Purchase
     Termination Event with respect to such Seller has occurred and is
     continuing.

          (u)  No Fraudulent Transfer.  Such Seller is not entering into this
     Agreement with the intent (whether actual or constructive) to hinder,
     delay, or defraud its present or future creditors and is receiving

          4.2  Representations and Warranties of the Sellers Relating to the
               -------------------------------------------------------------
Agreement and the Receivables.  Each Seller hereby represents and warrants to
- -----------------------------                                                
the Company on the Effective Date and on each Payment Date that with respect to
the Receivables being paid for as of such date:

          (a)  Eligible Receivable.  Other than with respect to Receivables
     which such Seller states in writing (in the applicable Daily Report) are
     not Eligible Receivables on such date, each Receivable is, as of its
     Payment Date, an Eligible Receivable.  The aggregate outstanding Principal
     Amount of Receivables sold by it on any Payment Date is correctly set forth
     on the Daily Report.

          (b)  Title; No Liens.  Such Seller is the sole legal and beneficial
     owner of such Receivables, and upon the sale of each Receivable of such
     Seller, the Company will become the sole legal and beneficial owner of such
     Receivable, free and clear of any Liens (except for Permitted Liens) and no
     effective financing statement or other instrument similar in effect
     covering all or any part of such Purchased Receivable, Related Property or
     Collections with respect thereto will at such time be on file against such
     Seller in any filing or recording office except such as have been filed in
     favor of the Company in accordance with this Agreement.

          4.3  Representations and Warranties of the Company.  The Company
               ---------------------------------------------              
hereby represents and warrants to itself as follows:

          (a)  Organization, Corporate Powers.  It is duly organized, validly
     existing and in good standing under the laws of the jurisdiction of its
     organization, has all requisite corporate power and authority to carry on
     its business as now conducted and, except where the failure to do so,
     individually or in the aggregate, could not reasonably be expected to
     result in a Material Adverse Effect, is qualified to do business in, and is
     in good standing in, every jurisdiction where such qualification is
     required and has the corporate power and authority to execute, deliver and
     perform each of the Transaction Documents and each other agreement or
     instrument contemplated hereby or thereby to which it is or will be a
     party.

          (b)  Authorization.  The Transactions are within the corporate powers
     of the Company and have been duly authorized by all requisite corporate
     and, if required, stockholder action.
<PAGE>
 
                                                                              19

          (c)  Enforceability.  Each of this Agreement and each of the other
     Transaction Documents to which it is a party has been duly executed and
     delivered by the Company and constitutes a legal, valid and binding
     obligation of the Company enforceable against it in accordance with its
     terms, except as enforceability may be limited by bankruptcy, insolvency,
     moratorium, reorganization or other similar laws affecting creditors'
     rights generally and except as enforceability may be limited by general
     principles of equity, regardless of whether such enforceability is
     considered in a proceeding in equity or at law.

          (d)  Accounting Treatment.  The Company will not prepare any financial
     statements that shall account for the transactions contemplated hereby, nor
     will it in any other respect (other than for tax purposes) account for the
     transactions contemplated hereby, in a manner that is inconsistent with the
     Company's ownership interest in the Receivables.


                                   ARTICLE V

                             AFFIRMATIVE COVENANTS

     or satisfied by it, and that such officer has obtained no knowledge of any
     Purchase Termination Event or Incipient Purchase Termination Event except
     as specified in such certificate; and

     Company may from time to time reasonably request.

failure to comply therewith could not have a Material Adverse Effect.  Each
Seller will

Obligors relating to the Purchased Receivables, except to the extent such
compliance would result in a violation of the laws, rules, regulations or orders
of any Governmental Authority.

          5.3  Preservation of Corporate Existence.  (i)  Preserve and maintain
               -----------------------------------

of its incorporation and (ii) qualify and remain qualified in good standing as a
foreign corporation in each jurisdiction where the nature of its business so
requires, except where the failure so to qualify would not, individually or in
the aggregate with other such failures, have a Material Adverse Effect shall be
given; provided, that notwithstanding the foregoing, any Seller may be
       --------

                      --------                                                 
may have Collections on its Receivables, whether or not sold to the Company,
deposited into the Designated Accounts or the Concentration Account;

               (ii)  To the extent that it shares any officers or other

     allocated among it and the Company, and it and the Company shall bear their
     fair shares of the salary and benefit costs associated with all such common
     officers and employees;

               (iii) To the extent that it jointly contracts with the Company
     to do business with vendors or service providers or to share overhead
     expenses, the costs incurred in so doing shall be allocated fairly between
     it and the Company, and it and the Company shall bear their fair shares of
     such costs.  To the extent that it contracts or does business with vendors

     the extent that it and the Company have offices in the same location, there
     shall be a fair and appropriate allocation of overhead costs between them,
     and each shall bear its fair share of such expenses;

               (v)  Not assume or guarantee any of the liabilities of the
          Company; and

               (vi) Take, or refrain from taking, as the case may be, all other
     actions that are necessary to be taken or not to be taken in order (x) to
     ensure that the assumptions and factual recitations set forth in the
     Specified Bankruptcy Opinion Provisions remain true and correct in all

          8.1  Subordinated Note.  On the Effective Date, the Company shall
               -----------------                                           
issue to WMI as agent for the Sellers, a subordinated note substantially in the
form of Exhibit A (the "Subordinated Note").  The aggregate principal amount of
the Subordinated Note at any time shall be equal to the difference between (a)
the aggregate principal amount of the issuance thereof and each addition to the
principal amount of the Subordinated Note with respect to each Seller pursuant
to the terms of subsection 2.3 minus (b) the aggregate amount of all payments
                               -----                                         
made in respect of the principal of the Subordinated Note.  All payments made in
respect of the Subordinated Note shall be allocated among the Sellers by the
Master Servicer.  Each Seller's interest in the Subordinated Note shall equal
the sum of each addition thereto allocated to such Seller pursuant to subsection
2.3(c) less the sum of each repayment thereof allocated to such Seller.  All
payments made in respect of the Subordinated Note shall be allocated, first, to
                                                                      -----    
pay accrued and unpaid interest thereon, and second, to pay the outstanding
                                             ------                        
principal amount thereof.  Interest on the outstanding principal amount of the
Subordinated Note (as such principal amount may have been increased pursuant to
the following proviso) shall accrue at the ABR in effect from time to time from
and including the Commencement Date and shall be paid on each Settlement Date
with respect to amounts accrued and not paid as of the last day of the preceding
Settlement Period and/or the maturity date thereof; provided, however, that
                                                    --------  -------      
accrued interest on the Subordinated Note which is not so paid may be added to
the principal amount of the Subordinated Note.  Principal not prepaid pursuant
to the terms hereof and of the other Transaction Documents shall be payable on
the maturity date thereof.  Default in the payment of principal or interest
under the Subordinated Note shall not constitute a default or event of default
or a Purchase Termination Event hereunder or a Termination Event under the
Receivables Transfer Agreement.

          8.2  Restrictions on Transfer of Subordinated Note.  Neither the
               ---------------------------------------------              
Subordinated Note, nor any right of any Seller to receive payments thereunder,
shall be assigned, transferred, exchanged, pledged, hypothecated, participated
or otherwise conveyed.

acquire from the Company, a senior undivided participating interest from time to

          (b)  In addition, to secure the obligation of the Company hereunder,
including, without limitation the obligations set forth in subsection 2.7, the
Company hereby assigns to the Administrative Agent, for the benefit of the
Participants, and grants to the Administrative Agent, for the benefit of the
Participants, a security interest in all its right, title and interest in, to
and under the Receivables Sale Agreement and the Receivables Sale Agreement
Guarantee, 
<PAGE>
 
including (i) all property assigned thereunder and all rights of the Company to

whether payable as fees, expenses, costs or otherwise, (ii) all rights of the
Company to receive proceeds of any insurance, indemnity, warranty or guaranty
with respect to such agreement, (iii) claims of the Company for damages arising

connection with such agreement (whether arising pursuant to such agreement or
otherwise available to the Company at law or in equity), including the rights of

in Section 9-306 of the UCC as in effect in the State of New York) thereof,
including all Recoveries relating thereto (the Pooled Property described in this
sentence being referred to herein as the "Transferred Agreements").

          (c)  In addition, to secure the obligations of the Company hereunder,
including, without limitation, the obligations set forth in subsection 2.7, the
Company hereby grants to the Administrative Agent, for the benefit of the
Participants, a security interest in all right, title and interest of the
Company in, to and under the following, whether now owned or hereafter acquired:

          (i)  all equipment in all its forms, wherever located, now or
     hereafter existing (including all software, data bases, materials, books,
     records, magnetic tapes, disks and cassettes relating to the Receivables
     and all other equipment in which information concerning the Receivables is
     stored), and all parts thereof and accessions thereto (any and all such
     equipment, parts and accessions being the "Equipment");

          (ii) all the following (the "Accounts"):

                  (A)  the Collection Account and the SPC Collection Account
          and, to the extent provided further herein, any interest in the
          Designated Accounts or the Concentration Account, all funds and other
          evidences of payment held therein and all certificates and
          instruments, if any, from time to time representing or evidencing such
          Account or any funds and other evidences of payment held therein;

                  (B)  any operating account or other accounts of the Company,
          all funds held therein and all certificates and instruments, if any,
          from time to time representing or evidencing any such operating
          account or any funds held therein;
<PAGE>
 
               (C)  all Cash Equivalents and all certificates and instruments
          from time to time representing or evidencing the Cash Equivalents;

               (D)  all notes, certificates of deposit and other instruments
          from time to time hereafter delivered or transferred to, or otherwise
          possessed by, the Administrative Agent for and on behalf of the
          Company in substitution for or in addition to any of the then-existing
          Accounts; and

               (E)  all interest, dividends, cash, instruments and other
          property from time to time received, receivable or otherwise
          distributed in respect of or in exchange for any and all of the then-
          existing Accounts; and

          (iii) all proceeds of or payments in respect of any and all of the
     foregoing (including proceeds that constitute property of the types
     described in clauses (i) and (ii) above and including Collections) and, to
     the extent not otherwise included, all payments under insurance (whether or
     not the Administrative Agent is the loss payee in respect thereof), or any
     indemnity, warranty or guaranty payable by reason of loss or damage to or
     otherwise with respect to any of the Pooled Property.

          (d)   In connection with the assignment, set over and conveyance to
the Participants pursuant to subsection 2.1(a), the Company, the Master Servicer
and the Participants agree that the Administrative Agent shall constitute a
"secured party" as defined in Section 9-105(m) of the UCC. Each reference in
this Agreement, unless the context otherwise requires, to the sale, assignment,
transfer, set over or conveyance of a Receivable or other Receivables Property
shall be construed as a reference to the sale, assignment, transfer, set over or
conveyance of the senior undivided participating interest in the Receivable and
the other Receivables Property to the Participants hereunder. In connection with
the foregoing assignment, the Company and the Master Servicer agree to deliver
to the Administrative Agent each item evidencing a Receivable or other
Receivables Property (including any original documents or instruments as are
necessary to effect such assignment) in which the transfer of an interest is
perfected under the UCC or otherwise solely by possession and not by filing a
financing statement or similar document.

          Notwithstanding the assignment of the Transferred Agreements set forth
in subsection 2.1(b), the Company does not hereby assign or delegate any of its
duties or obligations under the Transferred Agreements to the Administrative
Agent or the Participants and neither the Administrative Agent nor any
Participant accepts such duties or obligations, and the Company shall continue
to have the right and the obligation to purchase Receivables from the Sellers
thereunder from time to time.  The foregoing assignment, set-over and conveyance
does not constitute and is not intended to result in a creation or an assumption
by the Administrative Agent or the Participant, of any obligation of the Master
Servicer, the Company, any Seller or any 
<PAGE>
 
other Person in connection with the Receivables or under any agreement or
instrument relating thereto, including, without limitation, any obligation to
any Obligor.

          In connection with such assignments, the Company agrees to record and
file, at its own expense, any financing statements (and continuation statements
with respect to such financing statements when applicable) or, where applicable,
registrations in the appropriate records, (i) with respect to the Receivables
now existing and hereafter created and (ii) with respect to any other Pooled
Property a security interest in which may be perfected under the relevant UCC,
legislation or similar statute by such filing or registration, as the case may
be, in each case meeting the requirements of applicable law in such manner and
in such jurisdictions as are necessary to perfect and maintain perfection of the
assignment of the Receivables and such other Pooled Property (excluding returned
merchandise) to the Participants and the Administrative Agent, and to deliver a
file-stamped copy or certified statement of such financing statement or
registration or other evidence of such filing or registration to the
Administrative Agent not later than the 10th day after the Commencement Date.
The Administrative Agent shall be under no obligation whatsoever to file such
financing statement, or a continuation statement to such financing statement, or
to make any other filing or other registration under the UCC, other relevant
legislation or similar statute in connection with such transfer.  The
Administrative Agent shall be entitled to conclusively rely on the filings or
registrations made by or on behalf of the Company without any independent
investigation and the Company's obligation to make such filings as evidence that
such filings have been made.

          In connection with such assignments, the Company and the Master
Servicer further agree, at their own expense, on or prior to the Commencement
Date, to indicate, or to cause to be indicated, in their respective computer
files containing a master database of Receivables and to cause each Seller to
indicate in its records containing a master database of Receivables that the
Receivables have been conveyed to the Company or the Participants, as the case
may be, pursuant to the Receivables Sale Agreement or this Agreement,
respectively, for the benefit of the Participants.

          2.2  Participating Interest.  Subject to the terms and conditions set
               ----------------------                                          
forth herein (including, without limitation, subsections 2.3(c) and 6.2), each
Participant agrees during the Commitment Period to ratably purchase a
Participating Interest and ratably increase its Net Investment in an aggregate
amount that will not result in such Participant's Net Investment exceeding such
Participant's Commitment and the Net Investment of all Participants exceeding
the aggregate Commitments then in effect.  The senior undivided participating
interest of the Participants in the Receivables and the Receivables Property
(the "Participating Interest"; a Participant's Commitment Percentage of such
Participating Interest shall equal such Participant's "Participating Interest")
shall equal, at any date of determination thereof, the Net Investment at such
date and the Participating Interest of any Participant shall equal, at any date
of determination thereof, the Net Investment of such Participant at such date.
The Participating Interest shall, among other things, entitle the Participants
to receive the amounts distributable to the Participants pursuant to subsection
2.7, including, without limitation, Purchase 
<PAGE>
 
Discount Amounts which shall accrue thereon in accordance with this Agreement
and the payment of the Net Investment. The Company agrees to provide any
Participant upon its request with a certificate evidencing such Participant's
Participating Interest.

          2.3  Payment for Initial Transfer of a Participating Interest and any
               ----------------------------------------------------------------
Increase in Net Investment; Acquisition and Transfer Procedure.   (a)  The
- --------------------------------------------------------------            
Company shall notify the Administrative Agent of the amount of the initial
transfer and assignment of a Participating Interest or any request for an
Increase in Net Investment pursuant to this subsection 2.3.  The amount which
the Participants shall pay for such initial transfer and assignment or Increase
in Net Investment shall equal the amount of such initial transfer and assignment
or Increase in Net Investment, as the case may be.  Amounts payable to the
Company in respect of the initial transfer and assignment of a Participating
Interest or any Increase in Net Investment on such Closing Date shall be
obtained by the Administrative Agent from the Participants and paid by the
Administrative Agent to the Company in accordance with the provisions of
subsection 2.8(a).

          (b)  Subject to subsections 2.3(c) and 6.2, the initial transfer and
assignment of a Participating Interest or an Increase in Net Investment of the
Participants shall occur, upon notice from the Company, on any Business Day
during the Commitment Period (each date on which the initial transfer and
assignment of a Participating Interest in the Receivables or an Increase in Net
Investment of the Participants occurs hereunder being herein referred to as the
"Closing Date" applicable to such transfer and assignment or such increase, as
the case may be); provided, that the Company shall have given the Administrative
                  --------                                                      
Agent irrevocable notice (effective upon receipt) of such request substantially
in the form of Exhibit A hereto (the "Request for Transfer and Assignment") no
later than (i) if the initial transfer and assignment of a Participating
Interest or the Increase in Net Investment on such date is to be priced solely
with reference to ABR, 12:00 Noon (New York City time) on such Closing Date or
(ii) if all or a portion of the initial transfer and assignment of a
Participating Interest or the Increase in Net Investment is to be allocated to a
Fixed Tranche, 11:00 a.m. (New York City time) three Business Days prior to such
Closing Date; provided, further, that the provisions of this subsection 2.3(b) 
              --------  -------
shall not restrict the allocations of Collections pursuant to subsection 2.7.
Such notice shall state (i) the Closing Date, (ii) the amount of the initial
transfer and assignment of a Participating Interest or the Increase in Net
Investment, as the case may be, for the proposed transaction, (iii) what portion
thereof will be allocated to a Fixed Tranche and/or the Floating Tranche and
(iv) if any portion thereof is to be allocated to a Fixed Tranche, the length of
the Transfer Period therefor. After receipt by the Administrative Agent of the
Request for Transfer and Assignment from the Company, the Administrative Agent
shall promptly provide notice (which may be telephonic but shall be confirmed in
writing) to each Participant of the Closing Date and of the portion of the
Participating Interest or the Increase in Net Investment allocable to such
Participant on such Closing Date.
<PAGE>
 
          (c)  Each Participant shall have no obligation to acquire a
Participating Interest or to increase its Net Investment on any Closing Date
hereunder:

          (1)  unless, in the case of an Increase in Net Investment, the
     Increase in Net Investment for all Participants on such Closing Date is
     equal to at least $10,000,000 or an integral multiple of $1,000,000 in
     excess thereof;

          (2)  to the extent that, after giving effect to (A) in the case of the
     initial transfer and assignment of a Participating Interest, such transfer,
     and (B) in the case of an Increase in Net Investment, such Increase in Net
     Investment on such date, the Net Investment for all Participants would
     exceed the Maximum Transfer Amount; or

          (3)  if the Commitments of the Participants have terminated pursuant
     to Article IX.

The initial transfer and assignment of the Participating Interest or an Increase
in Net Investment allocable to the Participants as a group shall be allocated to
each Participant according to the Commitment Percentage of such Participant.

          2.4  Commitment Fees.  The Company agrees to pay to the Administrative
               ---------------                                                  
Agent, for the account of the Participants, a commitment fee (the "Commitment
Fee") for the Commitment Period, computed at the rate of 0.1875 of 1% per annum
on the average daily excess of the Maximum Commitment over the Net Investment
for each day during the period for which such Commitment Fee is payable.
Accrued Commitment Fees shall be payable in arrears, based on invoices submitted
by the Administrative Agent to the Company, on the Settlement Date occurring in
March, June, September and December and on the date of the termination of the
Commitment, commencing on March 20, 1998 and shall be paid in immediately
available funds to the Administrative Agent for distribution to the
Participants.

          2.5  Fee and Purchase Discount Amount Calculations.  (a)  Calculations
               ---------------------------------------------                    
of per annum rates under this Agreement shall be made on the basis of a 360-day
year for actual days elapsed, except that Commitment Fees and Purchase Discount
Amounts on the Floating Tranche determined by reference to the Prime Rate shall
be calculated on the basis of a 365- (or 366-, as the case may be) day year.
Each determination of the Adjusted LIBO Rate hereunder by the Administrative
Agent shall be conclusive and binding upon each of the parties hereto in the
absence of manifest error. Any change in the Purchase Discount Amount resulting
from a change in ABR or the Statutory Reserve Rate shall become effective as of
the opening of business on the day on which such change is announced.

          (b)  On any Business Day, the Company may, subject to paragraph (c)
below, elect to allocate all or any portion of the Net Investment not allocated
to a Fixed Tranche to one or more Fixed Tranches with Transfer Periods
commencing on such Business Day by giving the Administrative Agent irrevocable
written or telephonic (confirmed in writing) notice thereof, which notice must
be received by the 
<PAGE>
 
Administrative Agent prior to 1:00 p.m., New York City time, three Business Days
prior to such Business Day. Such notice shall specify (i) the applicable
Business Day, (ii) the Transfer Period for each Fixed Tranche to which a portion
of the Net Investment is to be allocated and (iii) the portion of the Net
Investment being allocated to each such Fixed Tranche. Promptly upon receipt of
each such notice, the Administrative Agent shall notify each Participant of the
contents thereof. If the Administrative Agent shall not have received timely
notice as aforesaid with respect to all or any portion of the Net Investment,
the Purchase Discount Amount on such amount shall be calculated by reference to
the ABR.

          (c)  Anything contained in this Agreement to the contrary
notwithstanding, (i) the portion of the Net Investment allocable to any Fixed
Tranche must be an amount equal to $10,000,000 or an integral multiple of
$1,000,000 in excess thereof, (ii) no more than ten Fixed Tranches shall be
outstanding at any one time and (iii) after the occurrence and during the
continuance of any Termination Event, at the end of the related Transfer Period
all of the Net Investment allocated to any Fixed Tranche shall be reallocated to
the Floating Tranche.

               ----------------------------                               
Company to the Participants or the Administrative Agent hereunder, whether on
account of fees or expenses or on account of amounts collected by the Company or
amounts payable by the Company pursuant to Article III or subsection 5.3, or
otherwise, is not paid by the Company or otherwise on the relevant Settlement

               -----------------------------------------------------
Reinvestment of Principal Collections.
- ------------------------------------- 

          (a)  (i)   The Administrative Agent shall establish and maintain in
the name of the Administrative Agent a trust account (the "Collection Account").
Collections deposited into the SPC Collection Account will be transferred to the
Collection Account as set forth in Article XII. All Collections otherwise
received by any Servicer, the Master Servicer or the Company shall be deposited
by it either to a Designated Account or into the Concentration Account as set
forth in Article XII. The Administrative Agent shall have sole and exclusive
dominion over and control of the Collection Account, and the Company, the
Sellers and the Master Servicer shall not have any dominion over or control of
any such account.

               (ii)  Amounts deposited in the Collection Account shall be
invested by the Administrative Agent as directed by the Master Servicer in Cash
Equivalents maturing not later than the next Business Day.

               (iii) Any earnings (net of losses and investment expenses) on
such invested funds in any Collection Account ("Investment Earnings") will be
treated as Collections and retained therein.
<PAGE>
 
          (iv)   Neither the Company nor the Master Servicer nor any Servicer
nor any Person claiming by, through or under the Company, any Servicer or the
Master Servicer shall have any right, title or interest in, or any control over
the use of, or any right to withdraw moneys from, the Collection Account, except
(A) the right to give directions for investments of amounts on deposit therein
as expressly provided for in paragraph (ii) above and (B) pursuant to the
authority granted to the Master Servicer in subsection 12.2, the Master Servicer
shall have the power, revocable by the Administrative Agent, to instruct the
Administrative Agent to make withdrawals from the Collection Account for the
purpose of carrying out the Administrative Agent's duties hereunder.  Delivery
of a Daily Report by the Master Servicer or a Servicer instructing the
Administrative Agent to make withdrawals from the Collection Account shall be
deemed to constitute a representation and warranty that such withdrawal is
authorized pursuant to the terms hereof and all conditions to such withdrawal
have been satisfied.  In the event that the Master Servicer or a Servicer fails
to deliver a Daily Report, the Administrative Agent may (but shall not be
obligated to) apply Receivable Proceeds in accordance with this subsection 2.7
to the payment of amounts to be paid to the Participants and the Administrative
Agent.  The Company agrees that all Receivable Proceeds shall be applied and
paid in accordance with this subsection 2.7.  Any Receivable Proceeds not
applied on any Business Day in accordance with this subsection 2.7 shall be
retained in the Collection Account until applied in accordance with this
subsection 2.7.

          (b)  Prior to the commencement of an Amortization Period, the
Collections, Retransfer Payments, Adjustment Payments and the other proceeds of
the Pooled Property deposited in the Collection Account (collectively,
"Receivable Proceeds") shall be applied by the Administrative Agent on each
Business Day (in accordance with the Daily Report provided by the Master
Servicer or a Servicer, upon which the Administrative Agent may conclusively
rely on), as follows:

               (i)    first, if such Business Day is a Settlement Date, to the
     payment of the Monthly Servicing Fee to the Master Servicer for the benefit
     of the Master Servicer and any Servicer or to a Substitute Servicer;

               (ii)   second, on each Purchase Discount Amount Payment Date to
     the payment in arrears of accrued Purchase Discount Amounts on such
     Purchase Discount Amount Payment Date to the Participants in respect of the
     Participating Interest;

               (iii)  third, to the payment of (x) the Commitment Fees and (y)
     any other amounts, if any, accrued and payable on such Business Day to the
     Administrative Agent and the Participants in respect of the Participating
     Interest or hereunder (including, without limitation, amounts payable under
     Article III);

               (iv)   fourth, to retain in the Collection Account the Reserve
     Amount for such Business Day;

               (v)    fifth, to the payments, if any, required by subsection
     2.12 on such Business Day;
<PAGE>
 
               (vi)   sixth, to the payment of the Company's indemnity
     obligations hereunder and, then, to the Company's operating account for the
     payment of the operating expenses of the Company incurred or reserved for
     on such Business Day; provided, that the aggregate amounts paid to the
                           --------                                        
     Company's operating account pursuant to this clause (v) shall not exceed,
     for any fiscal year of the Company, $250,000;

               (vii)  seventh, to the Company to pay for Receivables acquired
     from the Sellers pursuant to the Receivables Sale Agreement in the
     aggregate amount specified in the applicable Daily Report; provided, that
                                                                --------
     the Company may elect to (A) retain all or any portion of such amounts in
     the Collection Account and (B) on the next Reduction Date, if the Company
     shall have given the Administrative Agent irrevocable notice in accordance
     with subsection 2.11(b), have all or any portion of such amounts remitted
     to the Participants on such Reduction Date and have the Net Investment
     reduced accordingly (subject to the payment by the Company of any amounts
     required pursuant to subsection 3.3);

               (viii) eighth, to the extent such expenses are not paid
     pursuant to clause (vi) above, to the Company's operating account for the
     payment of the operating expenses of the Company incurred or reserved for
     such Business Day;

               (ix)   ninth, at the Company's option and subject to the terms of
     this Agreement and the Subordinated Note, to make payments on account of
     the Subordinated Note, in the aggregate amount specified in the applicable
     Daily Report; and

               (x)    tenth, at the Company's option and subject to the terms of
     this Agreement, to the Company to enable the Company to make payments on
     account of Restricted Payments in the aggregate amount specified in the
     applicable Daily Report, so long as the outstanding principal amount of the
     Subordinated Note shall be zero at the time of such payment and all accrued
     interest thereon shall have been paid in full;

provided, that
- --------      

                              (A)  in no event shall any Receivable Proceeds be
                      distributed from the Collection Account with respect to
                      clauses (v)-(x) above to the extent such distribution
                      would necessitate a payment under subsection 2.12;

                              (B)  in no event shall any Receivable Proceeds be
                      distributed from the Collection Account with respect to
                      clauses (ix) and (x) above if any Seller Repurchase
                      Payments or Seller Adjustment Payments are owing (whether
                      or not then due) to the Company and are unpaid;
<PAGE>
 
                    (C)  in no event shall any Receivable Proceeds be
               distributed from the Collection Account with respect to clauses
               (vii) and (viii) above (other than a distribution in accordance
               with the proviso in clause (vii)), if a Termination Event of a
               type set forth in subsection (f), (h)(ii), (i), (m) or (n) of
               Article IX (or a Potential Termination Event in respect thereof)
               has occurred and is continuing or would as a result of such
               payment; and

                    (E)  in no event shall any Receivable Proceeds be
               distributed from the Collection Account with respect to clauses
               (ix) and (x) above if any Termination Event or a Potential
               Termination Event with respect to a Termination Event of a type
               set forth in subsection (f), (g), (h)(ii), (i), (m) or (n) of
               Article IX shall have occurred and be continuing or would occur
               as a result of such payment.

          (c)  During any Amortization Period, all Receivable Proceeds shall be
applied by the Administrative Agent on each Business Day (in accordance with the
Daily Report provided by the Master Servicer or a Servicer, upon which the
Administrative Agent may conclusively rely) as follows:

               (i)    first, (x) to the payment of Monthly Servicing Fees of the
     Master Servicer or any Substitute Servicer and (y) to the payment of the
     reasonable operating expenses of the Company (subject to the limitations
     set forth in subsection 2.7(b)(vi));

               (ii)   second, to the payment on the last Business Day of each
     week to the Participants in respect of the Participating Interest first to
     the payment in arrears of accrued Purchase Discount Amounts and then to the
     payment of the Net Investment until such time as the Net Investment and
     Purchase Discount Amounts thereon shall have been paid in full;

               (iii)  third, after such time as the Net Investment and
     Purchase Discount Amounts have been paid in full to the payment to the
     Participants and the Administrative Agent of all other amounts (including,
     without limitation, amounts payable under Article III) that are payable to
     the Administrative Agent and its Affiliates and the Participants hereunder,
     until such amounts shall have been paid in full; and

               (iv)   fourth, after such time as the Net Investment and Purchase
     Discount Amounts thereon and all other amounts that are due and payable to
     the Administrative Agent and the Participants shall have been paid in full,
     the remainder to the Company.

          (d)  The Master Servicer shall as soon as possible but no later than
one Business Day after receipt of any Collections and other proceeds determine
whether or not they are with respect to Purchased Receivables and shall as soon
as possible 
<PAGE>
 
notify the Administrative Agent of such determination. The Administrative Agent
shall as soon as possible thereafter transfer any Collections that are not with
respect to Purchased Receivables from the Collection Account to the Master
Servicer for payment to the applicable Person; provided, that with respect to 
                                               --------
any Collections for which the Administrative Agent has not been provided such a
determination by the Master Servicer by the end of the fifth Business Day from
the date of receipt thereof, such Collections shall be deemed to be Collections
with respect to Purchased Receivables and no other Person shall have any rights
therein except to the extent provided in applicable state laws governing the
laws of restitution and mistake. Notwithstanding the foregoing, during any
Amortization Period, all cash collections and other proceeds received in respect
of an Obligor with respect to all Receivables of such Obligor shall be applied
first, to pay the outstanding principal balance of Purchased Receivables of 
- -----                        
such Obligor until Purchased Receivables with respect to such Obligor are paid
in full and second, amounts in excess thereof shall be paid to the Master 
            ------            
Servicer for payment to the Person legally entitled thereto to pay the
outstanding principal balance of all remaining Receivables with respect to such
Obligor. The Master Servicer agrees that in making each such determination with
respect to Collections and other proceeds, the Master Servicer represents and
warrants at such time, to the best of the Master Servicer's knowledge, that such
determination is true and correct.

          2.8  Payments; Pro Rata Treatment.  (a)  Subject to the terms and
               ----------------------------                                
conditions hereof, not later than 1:00 p.m. (New York City time) on each date on
which the Participants are notified to remit payments to the Administrative
Agent or as the Administrative Agent shall direct on account of any Increase in
Net Investment, each Participant shall make available to the Administrative
Agent or as the Administrative Agent shall direct an amount in immediately
available funds equal to the amount of such remittance calculated as provided
herein.  The Administrative Agent shall credit the proceeds of such payments (on
the date of receipt so long as the 1:00 p.m. deadline specified above is
satisfied) in a timely manner in accordance with the instructions of the
Company.

          (b)  Unless the Administrative Agent shall have been notified in
writing by any Participant prior to a Closing Date that such Participant will
not make the amount which would constitute its portion of the Participating
Interest or Increase in Net Investment on such date available to the
Administrative Agent, the Administrative Agent may assume that such Participant
has made such amount available to the Administrative Agent on such Closing Date,
and the Administrative Agent may, in reliance upon such assumption, make
available to the Company, a corresponding amount.  If such amount is made
available to the Administrative Agent on a date after such Closing Date, such
Participant shall pay to the Administrative Agent on demand an amount equal to
the product of (i) the daily average Federal Funds Effective Rate during such
period, (ii) the amount of such Participant's portion of the Participating
Interest or Increase in Net Investment and (iii) a fraction the numerator of
which is the number of days that elapse from and including such Closing Date to
the date on which such Participant's funds shall have become immediately
available to the Administrative Agent and the denominator of which is 360.  A
certificate of the Administrative Agent submitted to any Participant with
respect to 
<PAGE>
 
any amounts owing under this subsection 2.8(b) shall be conclusive, absent
manifest error. If such Participant's portion of the Participating Interest or
Increase in Net Investment is not in fact made available to the Administrative
Agent by such Participant within three Business Days of such Closing Date, the
Administrative Agent shall be entitled to recover such amount with interest
thereon at a per annum rate equal to the ABR, on demand, from the Company. No
provision contained in this subsection 2.8(b) shall prejudice any rights of the
Company against any Participant.

          (c)  Except where an amount is payable to a particular Participant,
all amounts payable to the Participants shall be paid to each Participant in an
amount equal to such Participant's Commitment Percentage of the aggregate amount
thereof payable to the Participants.

          2.9  Netting of Payments.  Anything contained in this Agreement to the
               -------------------                                              
contrary notwithstanding, the Administrative Agent may, in its sole discretion,
net any amounts the Administrative Agent is required to make available to the
Company on any day pursuant to subsection 2.7(b) or any other subsection of this
Agreement against any amounts the Administrative Agent is required to make
available to the Participants on such day pursuant to subsection 2.7(b) or any
other provision of this Agreement.  At the request of any Participant, the
Administrative Agent will provide an accounting of any amounts netted pursuant
to the preceding sentence.

          2.10  Termination or Reduction of Commitment.  The Company may on any
                --------------------------------------                         
Settlement Date, upon three Business Days prior written notice to the
Administrative Agent (effective upon receipt), (i) terminate the Participants'
Commitments hereunder or (ii) reduce the Maximum Commitment hereunder in an
amount equal to $10,000,000 or a whole multiple of $1,000,000 in excess thereof;
provided, that the Maximum Commitment may not be reduced below the Net
- --------                                                              
Investment.  After receipt by the Administrative Agent of any such notice from
the Company, the Administrative Agent shall promptly provide a copy of such
notice to each Participant.  Upon any such reduction, the Commitment of each
Participant shall be reduced pro rata according to the Commitment Percentage of
                             --- ----                                          
such Participant.  Upon any such termination or reduction as aforesaid, the
Maximum Commitment of the Participants shall terminate or be reduced, as the
case may be.  Any such termination shall not in any way affect the Company's
obligations under Article III hereof.  Once terminated or reduced, the
Commitments of the Participants cannot be reinstated unless otherwise agreed in
writing by all of the Participants.

          2.11  Optional Retransfer; Reduction of Net Investment.  (a)  On any
                ------------------------------------------------              
Settlement Date during the Amortization Period on which the Net Investment
equals 10% or less of the Net Investment as of the first day of the Amortization
Period, the Company shall have the option, exercisable upon one Business Day
prior notice to the Administrative Agent (effective upon receipt), to acquire
the Participants' total Participating Interest at a transfer price equal to the
Net Investment plus all Purchase Discount Amounts and all accrued and unpaid
fees to the date of such transfer plus any amounts payable pursuant to Article
III.  After receipt by the Administrative Agent of any such notice from the
Company, the Administrative Agent shall promptly provide a copy of such notice
to each Participant.
<PAGE>
 
          (b)  The Company may, in accordance with subsection 2.7(b)(vii),
reduce the Net Investment on any date (a "Reduction Date") which is a Business
Day, without premium or penalty (other than amounts payable pursuant to
subsection 3.3), upon at least three Business Days irrevocable notice to the
Administrative Agent, in the case of reductions in the Net Investment that are
part of any Fixed Tranche, and one Business Day irrevocable notice to the
Administrative Agent, in the case of reductions in the Net Investment that are
part of the Floating Tranche, specifying (a) the Tranches to be reduced, (b) the
date and amount of such reduction and (c) if such reduction is of a combination
of Fixed Tranche amounts and Floating Tranche amounts, the amount of reduction
allocable to each (and, with respect to such Fixed Tranche, each Tranche
thereof).  Upon receipt of any such notice, the Administrative Agent will
promptly notify each Participant thereof.  If any such notice is given, amounts
on deposit in the Collection Account shall be applied pursuant to subsection
2.7(b)(vi) on the date specified therein.  Each reduction of the Net Investment
pursuant to this subsection 2.11(b) shall be in an amount equal to the lesser of
(x) a whole multiple of $1,000,000 and (y) the Net Investment then outstanding.

          2.12  Mandatory Reductions in Net Investment.  (a)  On any Business
                --------------------------------------                       
Day during the Commitment Period on which the Net Investment exceeds the Maximum
Transfer Amount (except to the extent Excess Application Amounts in respect of
such excess are being held in a cash collateral account pursuant to subsection
2.12(c)), all Receivable Proceeds (after the payment of amounts pursuant to
clauses (i), (ii) and (iii) of subsection 2.7(b) on such Business Day) shall be
applied on such Business Day to reduce the Net Investment (and the Purchase
Discount Amounts accrued on the portion thereof so repaid) in such amount as
shall be necessary so that after giving effect to such payment there shall be no
such excess and, to the extent such Receivable Proceeds are not sufficient to
pay such excess (and the Purchase Discount Amount accrued thereon) on such
Business Day, all subsequent Receivable Proceeds (after the payment of amounts
pursuant to clauses (i), (ii) and (iii) of subsection 2.7(b) on such Business
Day) shall be applied to pay such excess (and the Purchase Discount Amounts
accrued thereon) until so paid.

          (b)  Notwithstanding anything to the contrary set forth in this
Agreement, any mandatory reduction hereunder shall be applied, unless the
Administrative Agent receives instructions from the Company otherwise, (i)
first, to the Floating Tranche, (ii) second, to any Fixed Tranche the then-
applicable Transfer Period with respect to which ends on the date of the
relevant payment and (iii) third, unless otherwise directed by the Company
pursuant to subsection 2.12(c), to the other Fixed Tranches as selected by the
Administrative Agent in its sole discretion; provided, that, in any event, the
                                             --------                         
Company shall pay such amounts, if any, required by subsection 3.3.

          (c)  In the event the amount of any mandatory reduction required to be
made on any date pursuant to this subsection 2.12 shall exceed the aggregate of
the amounts described in clauses (i) and (ii) of paragraph (b) above with
respect to such date (the amount of any such excess being called the "Excess
Application Amount"), the Company shall have the right to direct the
Administrative Agent to, in lieu of making such reduction in full, first apply
such reduction in the manner contemplated 
<PAGE>
 
by said clauses (i) and (ii) and deposit an amount equal to the Excess
Application Amount with the Administrative Agent in a cash collateral account
maintained (pursuant to documentation satisfactory to the Administrative Agent)
by and in the sole dominion and control of the Administrative Agent. Any amounts
so deposited shall be held by the Administrative Agent and applied to the
reduction of the applicable Fixed Tranches at the end of the current Transfer
Period applicable thereto. On any Business Day on which (x) collected amounts
remain on deposit in or to the credit of such cash collateral account after
giving effect to the payments made on such day pursuant to this paragraph (c)
and (y) the Company shall have delivered to the Administrative Agent a written
request or a telephonic request (which shall be promptly confirmed in writing)
that such remaining collected amounts be invested in the Cash Equivalents
specified in such request, the Administrative Agent shall use its reasonable
efforts to invest such remaining collected amounts in such Cash Equivalents;
provided, that the Administrative Agent shall have continuous dominion and 
- --------                         
full control over any such investments (and over any interest that accrues
thereon) to the same extent that it has dominion and control over such cash
collateral account and no Cash Equivalent shall mature after the end of the
Transfer Period for which it is to be applied. Unless a Termination Event or
Potential Termination Event then exists or would result, the Company shall have
the right to direct the Administrative Agent to withdraw any amount from such
cash collateral account if (i) the applicable Fixed Tranches have been reduced
to zero and the accrued Purchase Discount Amount thereon has been paid in full
or (ii) the Net Investment has otherwise ceased to exceed the Maximum Transfer
Amount.

          (d)  All payments under this subsection 2.12 shall be subject to
subsection 3.3 but otherwise without premium or penalty.  All payments in
reduction of the Net Investment under this subsection 2.12 shall be accompanied
by the Purchase Discount Amounts on the amount being paid accrued to the date of
payment.

                                Increased Costs

          3.1  Alternate Determination of Purchase Discount Amounts.  If prior
               ----------------------------------------------------           
to the commencement of any Transfer Period for a Fixed Tranche:

          (a)  the Administrative Agent determines (which determination shall be
     conclusive absent manifest error) that adequate and reasonable means do not
     exist for ascertaining the Adjusted LIBO Rate for such Transfer Period; or

          (b)  the Administrative Agent is advised by the Required Participants
     that the Adjusted LIBO Rate for such Transfer Period will not adequately
     and fairly reflect the cost to such Participants (or Participant) of making
     or maintaining their Eurodollar Participating Interests (or its Eurodollar
     Participating Interest) included in such Fixed Tranche for such Transfer
     Period;
<PAGE>
 
then the Administrative Agent shall give notice thereof to the Company and the
Participants by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Company and the Participants that
the circumstances giving rise to such notice no longer exist, (i) any request
under subsection 2.5(b) that requests the conversion of any Participating
Interest to, or continuation of any Participating Interest as, a Fixed Tranche
shall be ineffective and (ii) if any Request for Transfer and Assignment
requests a Fixed Tranche, such Participating Interest shall be made as a
Floating Tranche.

          3.2  Increased Costs.  (a)  If any Change in Law shall:
               ---------------                                   

          (i)   impose, modify or deem applicable any reserve, special deposit
     or similar requirement against assets of, deposits with or for the account
     of, or credit extended by, any Participant (except any such reserve
     requirement reflected in the Adjusted LIBO Rate); or

          (ii)  impose on any Participant or the London interbank market any
     other condition affecting this Agreement or Eurodollar Participating
     Interests of any such Participant;

and the result of any of the foregoing shall be to increase the cost to such
Participant of purchasing or maintaining any Eurodollar Participating Interests
(or of maintaining its obligation to purchase any such Participating Interest)
or to reduce the amount of any sum received or receivable by such Participant
(whether of Net Investment, payment of Purchase Discount Amount or otherwise),
then the Company will pay to such Participant such additional amount or amounts
as will compensate such Participant for such additional costs incurred or
reduction suffered.

          (b)  If any Participant determines that any Change in Law regarding
capital requirements has or would have the effect of reducing the rate of return
on such Participant's capital or on the capital of such Participant's holding
company, if any, as a consequence of this Agreement or its obligations pursuant
hereto to a level below that which such Participant or such Participant's
holding company could have achieved but for such Change in Law (taking into
consideration such Participant's policies and the policies of such Participant's
holding company with respect to capital adequacy), then from time to time the
Company will pay to such Participant such additional amount or amounts as will
compensate such Participant or such Participant's holding company for any such
reduction suffered.

          (c)  A certificate of a Participant setting forth the amount or
amounts necessary to compensate such Participant or its holding company as
specified in paragraph (a) or (b) of this subsection 3.2 shall be delivered to
the Company and shall be conclusive absent manifest error.  The Company shall
pay such Participant the amount shown as due on any such certificate within 30
days after receipt thereof.

          (d)  Failure or delay on the part of any Participant to demand
compensation pursuant to this subsection 3.2 shall not constitute a waiver of
such Participant's right to demand such compensation; provided, that the Company
                                                      --------                  
shall 
<PAGE>
 
not be required to compensate a Participant pursuant to this subsection 3.2 for
any increased costs or reductions incurred more than six months prior to the
date that such Participant notifies the Company of the Change in Law giving rise
to such increased costs or reductions and of such Participant's intention to
claim compensation therefor; provided, further, that, if the Change in Law
                             --------  -------                            
giving rise to such increased costs or reductions is retroactive, then the six-
month period referred to above shall be extended to include the period of
retroactive effect thereof.

          (e)  Notwithstanding any other provision of this subsection 3.2, no
Participant shall demand compensation for any increased cost or reduction or
other amount referred to above if it shall not at the time be the general policy
or practice of such Participant to demand such compensation in similar
circumstances under comparable provisions of other agreements.

          3.3  Indemnity.  In the event of (a) the payment of any Net Investment
               ---------                                                        
in respect of any Eurodollar Participating Interest other than on the last day
of a Transfer Period applicable thereto (including as a result of a Termination
Event), (b) the conversion of any Eurodollar Participating Interest other than
on the last day of the Transfer Period applicable thereto, (c) the failure to
transfer, convert, continue or reduce any Participating Interest on the date
specified in any notice delivered pursuant hereto or pursuant to subsection 2.12
or (d) the assignment of any Eurodollar Participating Interest other than on the
last day of the Transfer Period applicable thereto as a result of a request by
the Company pursuant to subsection 3.5, then, in any such event, the Company
shall compensate each Participant for the loss, cost and expense attributable to
such event.  In the case of a Eurodollar Participating Interest, the loss to any
Participant attributable to any such event shall be deemed to include an amount
determined by such Participant to be equal to the excess, if any, of (i) the
amount of interest that such Participant would pay for a deposit equal to the
Participating Interest for the period from the date of such payment, conversion,
failure or assignment to the last day of the then-current Transfer Period for
such Participating Interest (or, in the case of a failure to transfer, convert
or continue, the duration of the Transfer Period that would have resulted from
such transfer, conversion or continuation) if the interest rate payable on such
deposit were equal to the Adjusted LIBO Rate for such Transfer Period, over (ii)
                                                                       ----
the amount of interest that such Participant would earn on such amount for such
period if such Participant were to invest such amount for such period at the
interest rate that would be bid by such Participant (or an affiliate of such
Participant) for Dollar deposits from other banks in the eurodollar market at
the commencement of such period. A certificate of any Participant setting forth
any amount or amounts that such Participant is entitled to receive pursuant to
this subsection shall be delivered to the Company and shall be conclusive absent
manifest error. The Company shall pay such Participant the amount shown as due
on any such certificate within 10 days after receipt thereof.

          3.4  Taxes.  (a)  Any and all payments by or an account of any
               -----                                                    
obligation of the Company, any Servicer or the Master Servicer (each, a "Tax
Indemnifying Party") hereunder shall be made free and clear of and without
deduction for any 
<PAGE>
 
Indemnified Taxes or Other Taxes; provided, that if any Tax Indemnifying Party 
                                  --------                 
or the Administrative Agent shall be required to deduct any Indemnified Taxes or
Other Taxes from such payments, then (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this subsection) the Administrative
Agent or the relevant Participant receives an amount equal to the sum it would
have received had no such deductions been made, (ii) the Indemnifying Party
shall make such deductions and (iii) the Indemnifying Party or the
Administrative Agent, as the case may be, shall pay the full amount deducted to
the relevant Governmental Authority in accordance with applicable law.

          (b)  In addition, the Company shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

          (c)  The Company shall indemnify the Administrative Agent and each
Participant, within 10 days after written demand therefor, for the full amount
of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other
Taxes imposed or asserted on or attributable to amounts payable under this
subsection) paid by the Administrative Agent or such Participant, as the case
may be, and any penalties, interest and reasonable expenses arising therefrom or
with respect thereto, whether or not such Indemnified Taxes or Other Taxes were
correctly or legally imposed or asserted by the relevant Governmental Authority.
A certificate as to the amount of such payment or liability delivered to the
Company by a Participant or by the Administrative Agent on its own behalf or on
behalf of a Participant shall be conclusive absent manifest error.

          (d)  As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by any Tax Indemnifying Party to a Governmental Authority, such Tax
Indemnifying Party shall deliver to the Administrative Agent the original or a
certified copy of a receipt issued by such Governmental Authority evidencing
such payment, a copy of the return reporting such payment or other evidence of
such payment reasonably satisfactory to the Administrative Agent.

          (e)  Each Foreign Participant shall deliver to the Company and the
Administrative Agent two copies of either U.S. Internal Revenue Service Form
1001 or Form 4224, or, in the case of a Foreign Participant claiming exemption
from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code
with respect to payments of "portfolio interest", a Form W-8, or any subsequent
versions thereof or successors thereto (and, if such Foreign Participant
delivers a Form W-8, an annual certificate representing that such Foreign
Participant is not a "bank" for purposes of Section 881(c) of the Code, is not a
10-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Code)
of the Company and is not a controlled foreign corporation related to the
Company (within the meaning of Section 864(d)(4) of the Code)), properly
completed and duly executed by such Foreign Participant claiming that it is
entitled to a complete exemption from U.S. federal income withholding tax on all
payments by the Company under this Agreement. Such forms shall be delivered by
each Foreign Participant on or before the date it becomes a party to this
Agreement, assuming its Participating Interest is properly classified as
indebtedness for
<PAGE>
 
United States federal income tax purposes. In addition, each Foreign Participant
shall deliver such forms promptly upon the obsolescence or invalidity of any
form previously delivered by such Foreign Participant. Each Foreign Participant
shall promptly notify the Company at any time it determines that it is no longer
in a position to provide any previously delivered certificate to the Company (or
any other form of certification adopted by the U.S. taxing authorities for such
purpose). Notwithstanding any other provision of this subsection 3.4,(e), a
Foreign Participant shall not be required to deliver any form pursuant to this
subsection 3.4(e) (i) that such Foreign Participant is not legally able to
deliver or (ii) if the Participating Interests have been characterized as
anything other than indebtedness for United States income tax purposes.

          (f)  Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this subsection
3.4 shall survive the termination of this Agreement.

          3.5  Mitigation Obligations; Replacement of Participants.  If any
               ---------------------------------------------------         
Participant requests compensation under subsection 3.2, or if the Company is
required to pay any additional amount to any Participant or any Governmental
Authority for the account of any Participant pursuant to subsection 3.4, then
such Participant shall use reasonable efforts (consistent with legal and
regulatory restrictions) to file any certificate or document requested by the
relevant Tax Indemnifying Party or to designate a different lending office for
funding or booking its Participating Interest hereunder or to assign its rights
and obligations hereunder to another of its offices, branches or affiliates, if,
in the judgment of such Participant, such filing, designation or assignment (i)
would eliminate or reduce amounts payable pursuant to subsection 3.2 or 3.4, as
the case may be, in the future and (ii) would not subject such Participant to
any unreimbursed cost or expense and would not otherwise be disadvantageous to
such Participant.  The Company hereby agrees to pay all reasonable costs and
expenses incurred by any Participant in connection with any such designation or
assignment.

Agent shall, at the expense of

request to evidence the termination of the ownership interest of the
Participants in the Receivables and the payment of all amounts owing pursuant to
and in connection with this Agreement.

     Receivables, and upon the sale of each Receivable, the Participants will

     right, title and interest of the Company in the Receivables and the Related
     Property or, if this Agreement does not effect a transfer and assignment of
     such an ownership interest, it effects a grant of a "security interest" (as
     defined in the Uniform Commercial Code as in effect in the State of New
     York) in such property to the Participants, which, in the case of existing
     Receivables and the Related Property is enforceable upon execution and
     delivery of this Agreement, and which will be enforceable with respect to
     such Receivables and the Related Property hereafter created and the
     proceeds thereof upon such creation. On or prior to the initial Closing
     Date, all filings and other acts necessary or advisable (including but not
     limited to all filings and other acts necessary or advisable under the
     Uniform Commercial Code of each relevant jurisdiction) have been made or
     performed in order to grant the Participants a first priority perfected
     ownership interest in respect of all Receivables acquired by the Company
     and Related Property. On the Commencement Date and, in the case of the
     Receivables hereafter created and the proceeds thereof, upon the creation
     thereof, the Participants shall have a first priority perfected ownership
     or security interest in such property.

          (c)  The offices at which the Company keeps its records concerning the
     Receivables either (x) are located at the addresses set forth on Schedule 2
     or (y) have been reported to the Administrative Agent in accordance with

     office of the Company is located at the address set forth on Schedule 2 (as
     such location may be changed from time to time in accordance with
     subsection 8.21 of this Agreement) and is the place where the Company is
     "located" for the purposes of Section 9-103(3)(d) of the UCC as in effect
     in the State of New York.  The State and county where the chief executive
     office of the Company is "located" for the purposes of Section 9-103(3)(d)
     of the UCC as in effect in the State of New York has not changed in the
     past four months.

          (d)  On the date each Receivable transferred to the Participants is so
     transferred, each such Receivable that is included in the calculation of
     the amount of Eligible Receivables on such date is an Eligible Receivable.
     Each Receivable that is classified by the Company as an Eligible Receivable
     in any document or report (including, without limitation, any Daily Report)
     delivered hereunder shall be a Receivable with respect to which all of the
     criteria contained in the definition of "Eligible Receivable" hereunder are
     satisfied.

          The representations and warranties set forth in this subsection 5.2
shall survive the initial transfer of a Participating Interest and any Increase
in Net Investment.  Upon discovery by the Company, any Participant or the
Administrative Agent of a breach of any of the foregoing representations and
warranties, the Person discovering such breach shall give prompt written notice
to such other Persons.

the representations or warranties of the Company contained in subsection 5.2 in
any material respects or the Company shall breach any covenant contained in
Article VIII then upon the earlier to occur of the discovery of such event by
the Company, or receipt by the Company of written notice of such event given by
the Administrative Agent, the outstanding Principal Amount of Eligible
Receivables used to calculate the amount of Aggregate Eligible Receivables shall
be reduced by the Principal Amount of Receivables as to which such
representations and warranties were breached; provided, however, that (i) prior
                                              --------  -------
to the Amortization Period, to the extent that such a reduction would cause the
Invested Percentage to be more than the Maximum Invested Percentage, the Company
agrees to acquire such Receivables and any Related Property with respect thereto
on the terms and conditions set forth in paragraph (b) below and (ii) during the
Amortization Period, the Company agrees to acquire such Receivables and any
Related Property with respect thereto on the terms and conditions set forth in
paragraph (b) below.

          (b)  If any breach of a representation or warranty or other event
which necessitates the Company's reacquisition of a Receivable pursuant to
paragraph (a) above remains uncured, the Company shall acquire such Receivable
and any Related Property with respect thereto by depositing into the Collection
Account in immediately available funds no later than the fifth Business Day
after discovery or notice of such breach, an amount equal to (i) prior to an
Amortization Period, the lesser of (A) the amount necessary to cause the
Invested Percentage to equal the Maximum Invested Percentage and (B) the
Principal Amount of such Receivable or (ii) during an Amortization Period, the
Principal Amount of such Receivables (a payment pursuant to clause (ii), a
"Retransfer Payment").  Upon deposit of the Retransfer Payment and written
notice from the Company to the Administrative Agent that such Retransfer Payment
has been made, the Participants shall automatically and without further action
be deemed to transfer, assign, set-over and otherwise convey to the Company,
free and clear of any Lien created by the Participants but otherwise without
recourse, representation or warranty, all the right, title and interest of the
Participants in and to such Receivable, all Related Property with respect
thereto, all monies due or to become due with respect thereto and all proceeds
thereof and such reacquired Receivable shall be treated by the Participants as
collected in full as of the date on which it was transferred.  The
Administrative Agent shall execute such documents and instruments of transfer or
assignment and take such other actions as shall reasonably be requested by the
Company to effect the conveyance of such Receivables pursuant to this subsection
5.3 and Collections relating thereto.

indemnified to its satisfaction by the Participants against any and all
liability and expense which may be incurred by it by reason of taking or

or otherwise), prospects or creditworthiness of the Company, any Servicer or the
Master Servicer which may come into the possession of the Administrative Agent
or any of its officers, directors, employees, agents, attorneys-in-fact or

Company and the Master Servicer to do so), ratably according to their respective
Commitment Percentages in effect on the date on which indemnification is sought
under this subsection 10.7, from and against any and all subsection 11.3(b)(i)

that no Participant shall be liable for the payment of any portion of such
Indemnified Liabilities resulting from the Administrative Agent's gross
negligence or willful misconduct. The agreements in this subsection 10.7 shall

Participating Interest hereunder, the collection of all Receivables, the
termination of this Agreement and the payment of all amounts payable hereunder.

Administrative Agent and its affiliates may make loans to, accept deposits from
and generally engage in any kind of business with the Company, the Servicers,

powers, privileges and duties of the retiring Administrative Agent and the
retiring Administrative Agent shall be discharged from its duties and
obligations hereunder. After the Administrative Agent's resignation hereunder,

workout, restructuring or negotiations in respect thereof, including the
reasonable fees, charges and disbursements of Simpson Thacher & Bartlett,
counsel for the Administrative Agent, and, the reasonable fees, charges and
disbursements of any other counsel (including the reasonable allocated costs of
internal counsel if a Participant elects to use internal counsel in lieu of
outside counsel) for the Administrative Agent or any Participant (but no more
than one such counsel for any Participant).

          (b)  The Company agrees to indemnify the Administrative Agent, each
Participant and each of their respective directors, officers, employees and
agents (each such Person being called an "Indemnitee") against, and to hold each
Indemnitee harmless from, any and all losses, claims, damages, liabilities and
related expenses, including reasonable counsel fees, charges and disbursements,
incurred by or asserted against any Indemnitee arising out of, in any way
connected with, or as a result of (i) the execution or delivery of this
Agreement or any other Transaction Document or any agreement or instrument
contemplated thereby, the performance by the parties thereto of their respective
obligations thereunder or the consummation of the Transactions and the other
transactions contemplated thereby, (the "subsection 11.3(b)(i) Indemnified
Liabilities") (ii) the use of the proceeds of the initial transfer and
assignment of the Participating Interest and of any Increases in Net Investment,
(iii) any Environmental Liability related in any way to the Company, or (iv) any
claim, litigation, investigation or proceeding relating to any of the foregoing,
whether or not any Indemnitee is a party thereto; provided, that such indemnity
                                                  --------                     
shall not, as to any Indemnitee, be available to the extent that such losses,
claims, damages, liabilities or related expenses (A) are determined by a court
of competent jurisdiction by final and nonappealable judgment to have resulted
from the gross negligence or wilful misconduct of such Indemnitee (treating, for
this purpose only, any Participant and its directors, officers, employees and
agents as a single Indemnitee) or (B) arise from (x) any Receivable which
becomes a Charge-Off as a result of non-payment by the Obligor with respect
thereto, (y) any action taken, or omitted to be taken, by any Servicer which is
not an Affiliate of WMI, or (z) any action taken by the Participants in
collecting from an Obligor.

          (d)  The provisions of this subsection 11.3 shall remain operative and
in full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of all or any portion of the Net Investment, the invalidity or
unenforceability of any term or provision of this Agreement or any other
Transaction Document, or any investigation made by or on behalf of the
Administrative Agent or any Participant.  All amounts due under this subsection
11.3 shall be payable on written demand therefor.

          11.4  Successors and Assigns; Assignments; Participations.  (a)  The
                ---------------------------------------------------           
provisions of this Agreement shall be binding upon and inure to the benefit of
the Company, the Participants, the Master Servicer, the Servicers, the
Administrative Agent and their respective successors and assigns, except that
the Company, the Servicers and the Master Servicer may not assign or transfer
any of its or their rights or obligations under this Agreement without the prior
written consent of each Participant (and any attempted assignment or transfer by
the Company without such

                                                                              48

consent shall be null and void). Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby and, to the
extent expressly contemplated hereby, the Affiliates of each of the
Administrative Agent and the Participants) any legal or equitable right, remedy
or claim under or by reason of this Agreement.

          (b)  Any Participant may assign to one or more assignees all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Participating Interest and any Commitment of such Participant);
provided, that (i) except in the case of an assignment to a Participant or an
- --------                                                                     
Affiliate of a Participant, each of the Company and the Administrative Agent
must give their prior written consent to such assignment (which consent shall
not be unreasonably withheld and the parties hereto agree that the potential
payment of amounts under subsections 3.2, 3.3 or 3.4 to such assignee does not
constitute a basis upon which to withhold such consent), (ii) except in the case
of an assignment to a Participant or an Affiliate of a Participant or an
assignment of the entire remaining amount of the assigning Participant's
Commitment, the amount of the Commitment of the assigning Participant subject to
each such assignment (determined as of the date the Assignment and Acceptance
with respect to such assignment is delivered to the Administrative Agent) shall
not be less than $5,000,000 unless each of the Company and the Administrative
Agent otherwise consent, (iii) each partial assignment shall be made as an
assignment of a proportionate part of all the assigning Participant's rights and
obligations under this Agreement, (iv) the parties to each assignment shall
execute and deliver to the Administrative Agent an Assignment and Acceptance,
together with a processing and recordation fee of $3,500, and (v) the assignee,
if it shall not be a Participant, shall deliver to the Administrative Agent an
Administrative Questionnaire; provided, further, that any consent of the Company
                              --------  -------                                 
otherwise required under this paragraph shall not be required if a Termination
Event under clause (f) of Article IX has occurred and is continuing.  Upon
acceptance and recording pursuant to paragraph (d) of this subsection, from and
after the effective date specified in each Assignment and Acceptance, the
assignee thereunder shall be a party hereto and, to the extent of the interest
assigned by such Assignment and Acceptance, have the rights and obligations of a
Participant under this Agreement, and the assigning Participant thereunder
shall, to the extent of the interest assigned by such Assignment and Acceptance,
be released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all of the assigning Participant's rights and
obligations under this Agreement, such Participant shall cease to be a party
hereto but shall continue to be entitled to the benefits of subsections 3.2,
3.3, 3.4 and 11.3). Any assignment or transfer by a Participant of rights or
obligations under this Agreement that does not comply with this paragraph shall
be treated for purposes of this Agreement as a sale by such Participant of a
participation in such rights and obligations in accordance with paragraph (e) of
this subsection.

          (c)  The Administrative Agent, acting for this purpose as an agent of
the Company, shall maintain at one of its offices in The City of New York a copy
of each Assignment and Acceptance delivered to it and a register for the
recordation of the
<PAGE>
 
                                                                              49

names and addresses of the Participants, and the Commitment of, and the Net
Investment of, each Participant pursuant to the terms hereof from time to time
(the "Register"). The entries in the Register shall be conclusive, and the
Company, the Administrative Agent and the Participants may treat each Person
whose name is recorded in the Register pursuant to the terms hereof as a
Participant hereunder for all purposes of this Agreement, notwithstanding notice
to the contrary.

          (d)  Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Participant and an assignee, the assignee's completed
Administrative Questionnaire (unless the assignee shall already be a Participant
hereunder), the processing and recordation fee referred to in paragraph (b) of
this subsection and any written consent to such assignment required by paragraph
(b) of this subsection, the Administrative Agent shall accept such Assignment
and Acceptance and record the information contained therein in the Register.  No
assignment shall be effective for purposes of this Agreement unless it has been
recorded in the Register as provided in this paragraph.

          (e)  Any Participant may, without the consent of the Company or the
Administrative Agent, sell participations to one or more banks or other entities
(an "Additional Participant") in all or a portion of such Participant's rights
and obligations under this Agreement (including all or a portion of its
Participating Interest and any Commitment of any Participant); provided, that
                                                               --------      
(i) such Participant's obligations under this Agreement shall remain unchanged,
(ii) such Participant shall remain solely responsible to the other parties
hereto for the performance of such obligations and (iii) the Company, the
Administrative Agent and the other Participants shall continue to deal solely
and directly with such Participant in connection with such Participant's rights
and obligations under this Agreement.  Any agreement or instrument pursuant to
which a Participant sells such a participation shall provide that such
Participant shall retain the sole right to enforce this Agreement and to approve
any amendment, modification or waiver of any provision of this Agreement;
provided, that such agreement or instrument may provide that such Participant
- --------                                                                     
will not, without the consent of the Additional Participant, agree to any
amendment, modification or waiver described in the first proviso to subsection
11.7(b) that affects such Additional Participant.  Subject to paragraph (f) of
this subsection, the Company agrees that each Additional Participant shall be
entitled to the benefits of subsections 3.2, 3.3 and 3.4 to the same extent as
if it were a Participant and had acquired its interest by assignment pursuant to
paragraph (b) of this subsection.

          (f)  An Additional Participant shall not be entitled to receive any
greater payment under subsection 3.2 or 3.4 than the applicable Participant
would have been entitled to receive with respect to the participation sold to
such Additional Participant, unless the sale of the participation to such
Additional Participant is made with the Company's prior written consent. An
Additional Participant that would be a Foreign Participant if it were a
Participant shall not be entitled to the benefits of subsection 3.4 unless the
Company is notified of the participation sold to such Additional Participant and
such Additional Participant

agrees, for the benefit of the Company, to comply with subsection 3.4(e) as
though it were a Participant.

          (g)  Any Participant may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement to secure
obligations of such Participant, including any such pledge or assignment to a
Federal Reserve Bank, and this subsection shall not apply to any such pledge or
assignment of a security interest; provided, that no such pledge or assignment
                                   --------                                   
of a security interest shall release a Participant from any of its obligations
hereunder or substitute any such assignee for such Participant as a party
hereto.

          (h)  Each Participant that is a special-purpose securitization conduit
and has a Conduit Party that provides liquidity and/or credit facilities in
connection with such conduit's pro rata share of the Participating Interest
shall be entitled to receive payments pursuant to Article III as though such
Conduit Party were a Participant hereunder but no such payment shall exceed the
amount such conduit shall be obligated to pay to such Conduit Party pursuant to
similar sections of the liquidity and/or credit facilities agreement between
such conduit and such Conduit Party.  No conduit shall be entitled to receive
any payment contemplated by subsection 3.4 if the Conduit Party with respect to
which such payment is being claimed could not have satisfied the requirements of
subsection 3.4(e) (if such Conduit Party were a Participant).

          11.5  GOVERNING LAW.  THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
                -------------                                                   
THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, CONSTRUED AND INTERPRETED
IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

          11.6  No Waiver; Cumulative Remedies.  No failure to exercise and no
                ------------------------------                                
delay in exercising, on the part of the Administrative Agent or the
Participants, any right, remedy, power or privilege hereunder, shall operate as
a waiver thereof, nor shall any single or partial exercise of any right, remedy,
power or privilege hereunder preclude any other or further exercise thereof or
the exercise of any other right, remedy, power or privilege.  The rights,
remedies, powers and privileges herein provided are cumulative and not
exhaustive of any rights, remedies, powers and privileges provided by law.

          11.7  Amendments and Waivers.  Neither this Agreement nor any terms
                ----------------------                                       
hereof may be amended, supplemented, modified or waived except in accordance
with the provisions of this subsection 11.7.  The Required Participants may, or,
with the written consent of the Required Participants, the Administrative Agent
may, from time to time, (a) enter into with the Company, the Master Servicer and
the Servicers written amendments, supplements or modifications hereto for the
purpose of adding any provisions to this Agreement or changing in any manner the
rights of the Participants, the Company, the Servicers or the Master Servicer
hereunder or (b) waive in a written instrument, on such terms and conditions as
the Required Participants or the Administrative Agent, as the case may be, may
specify in such instrument, any of the requirements of this Agreement or any
default or Termination Event and its consequences; provided, however, that no
                                                   --------  -------

amendment, supplement or modification shall (i) extend the Scheduled Termination
Date; or reduce the rate or extend the time of payment of any Purchase Discount
Amount or Commitment Fee; or extend the time of payment of any mandatory
reduction of the Net Investment; or modify subsection 2.12 so that the fact that
the Net Investment exceeds the Maximum Transfer Amount does not necessitate a
mandatory reduction in the Net Investment; or change the definition of "Maximum
Invested Percentage" or consent to any amendment to subsection 2.6 of the
Receivables sale Agreement; or increase the amount of any Participant's
Commitment; or amend, modify or waive any provision of this subsection 11.7; or
reduce the percentage specified in the definition of Required Participants; or
consent to the assignment or transfer by the Company, any Servicer or the Master
Servicer of any of their respective rights and obligations under this Agreement
(except in accordance with Article XII); or release any substantial portion of
the Pooled Property (other than pursuant to subsection 5.3 or 12.7); in each
case without the written consent of each Participant directly affected thereby
or (ii) amend, modify or waive any provision of Article X without the written
consent of the Administrative Agent. Any such waiver and any such amendment,
supplement or modification shall apply equally to each of the Participants and
shall be binding upon the Company, the Servicers, the Master Servicer, the
Participants, the Administrative Agent and all future holders of a Participating
Interest. In the case of any waiver, the Company, the Servicers, the Master
Servicer, the Participants and the Administrative Agent shall be restored to
their former position and rights hereunder, any default or Termination Event
waived shall be deemed to be cured and not continuing; but no such waiver shall
extend to any subsequent or other default or Termination Event, or impair any
right consequent thereon.

          11.8  Severability.  Any provision of this Agreement which is
                ------------                                           
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                 -----------------------------------------------               
to subsection 11.18, although it is the intent of the parties to this Agreement
that the conveyance of the Company's right, title and interest in, to and under
the Receivables and the Related Property pursuant to this Agreement shall
constitute a purchase and sale and not a loan, in the event that such conveyance
is deemed to create a loan, the Company hereby grants to the Administrative
Agent, for the benefit of the Participants, a perfected first priority security
interest in all of the Company's present and future right, title and interest
in, to and under the Receivables and the Related Property to secure the payment
of the applicable Net Investment interest thereon and the other fees and

for the benefit of the Participants.

          (b)  Each Servicer hereby grants to the Administrative Agent on behalf
of the Participants a first priority security interest in all of the Servicer's

Participating Interest of the Net Investment, or any Purchase Discount Amount in
respect thereof, or receive any collateral in respect thereof (whether
voluntarily or involuntarily, by set-off, pursuant to events or proceedings of
the nature referred to in paragraph (f) of Article IX, or otherwise) in a
greater proportion than any such payment to and collateral received by any other
Participant, if any, in respect of such other Participant's Participating
Interest of the Net Investment, or any Purchase Discount Amount in respect
thereof, such benefitted Participant shall acquire for cash from the other
Participants such portion of each such other Participant's Participating
Interest of the Net Investment, or shall provide such other Participants with
the benefits of any such collateral, or the proceeds thereof, as shall be
necessary to cause such benefitted Participant to share the excess payment or
benefits of such collateral or proceeds ratably with each of the Participants;

provided by law, each Participant shall have the right, without prior notice to
the Company, any such notice being expressly waived by the Company to the extent
permitted by applicable law, upon any amount, other than amounts in respect of
Net Investment and the Purchase Discount Amounts with respect thereto, becoming
payable by the Company hereunder to set off and appropriate and apply against
such amount any and all deposits (general or special, time or demand,
provisional or final), in any currency, and any other credits, indebtedness or
claims, in any currency, in each case whether direct or indirect, absolute or
contingent, matured or unmatured, at any time held or owing by such Participant
or any branch or agency thereof to or for the credit or the account of the
Company.  Each Participant agrees promptly to notify the Company and the
Administrative Agent after any such set-off and application made by such
Participant; provided, that the failure to give such notice shall not affect the

and each of the parties hereto hereby irrevocably and unconditionally agrees
that all claims in respect of any such action or proceeding may be heard and

jurisdictions by suit on the judgment or in any other manner provided by law.

have to bring any action or proceeding relating to this Agreement or the other
Transaction Documents against the Company, the Master Servicer or any Servicer
or their properties in the courts of any jurisdiction.

          (b)  Each of the Company, the Master Servicer and each Servicer hereby
irrevocably and unconditionally waives, to the fullest extent it may legally and
effectively do so, any objection which it may now or hereafter have to the
laying of venue of any suit, action or proceeding arising out of or relating to
this Agreement or the other Transaction Documents in any New York State or
Federal court.  Each of the parties hereto hereby irrevocably waives, to the
fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

Administrative Agent, transfer the Designated Accounts to the name of the
Administrative Agent, which shall hold such account as agent for the benefit of
(1) with respect to Purchased Receivables Collections, the Participants and the

Agreement as of the Business Day Received (as defined in the immediately
succeeding sentence).  As used herein, the term "Business Day Received" shall

Servicer, the Master Servicer or the Company shall be deposited by it to a
Designated Account as soon as possible after receipt thereof, such deposit to

Obligor, be deposited directly into the Concentration Account.

          (ii)  All Collections deposited in the Concentration Account shall be
transferred to the SPC Collection Account on the same day that they are
deposited in the Concentration Account. The Master Servicer, the Servicers and
the Company agree that no amounts may be withdrawn from the Concentration
Account on any day until the amount of Purchased Receivables Collections
deposited therein on such day have been transferred to the SPC Collection
Account. If within five days after an amount has been deposited in the
Concentration Account, the Master Servicer or the Servicers are not able to
determine whether or not such amount is a Purchased Receivables Collection or a
WMI Collection, such amount shall be deemed to be a Purchased Receivables
Collection and shall immediately be transferred to the SPC

          12.2  Collections by the Servicers; Indemnity.  (a)  The Master
                ---------------------------------------                  
Servicer and each Servicer shall manage the servicing and administration of the
Receivables, the collection of payments due under the Receivables and the
charging off of any Receivables as uncollectible, all in accordance with the
Policies, the 
<PAGE>
 
                                                                              60

Company Policies and all the terms and provisions of this Agreement. The Master
Servicer and each Servicer shall have full power and authority, acting alone or
through any party properly designated by it hereunder, to do any and all things
in connection with such servicing and administration which it may deem necessary
or desirable, but at all times subject to the terms of this Agreement. Without
limiting the generality of the foregoing and subject to subsection 12.7, the
Master Servicer and each Servicer agree to cause each Subsidiary of the Master
Servicer to continue to perform such servicing functions with respect to the
Receivables originated by such Subsidiary that such Subsidiary has historically
performed; provided that the Master Servicer and each Servicer shall remain
liable for the failure of any such Subsidiary to perform such functions and each
Servicer or its designee is hereby authorized and empowered to give direction to
the Administrative Agent with respect to withdrawals from, and payments to, the
Collection Account in accordance with the Daily Report and as otherwise
specified in this Agreement. The Master Servicer and each Servicer will, at its
cost and expense and as agent for the Participants and the Company, use its best
efforts to collect, consistent with its past practices, as and when the same
becomes due, the amount owing on each Receivable for which it is the Servicer.
No Servicer will make any material changes that deviate from the Policies or the
Company Policies in its administrative, servicing and collection systems without
the prior written approval of the Required Participants. In the event of default
under any Receivable, the responsible Servicer shall have the power and
authority, on behalf of the Participants and the Company, to take such action in
respect of such Receivable as such Servicer may reasonably deem advisable. In
the enforcement or collection of any Receivable, each Servicer shall be entitled
to sue thereon in (i) its own name, (ii) if, but only if, the Administrative
Agent consents in writing, as agent of the Participants, or (iii) if, but only
if, the Company consents in writing, as agent for the Company. In no event shall
any Servicer or the Master Servicer be entitled to take any action which would
make the Administrative Agent or any of the Participants or the Company a party
to any litigation without the express prior written consent of the
Administrative Agent or each such Participant or the Company, as the case may
be.

          (b)  The Master Servicer and the Servicers which are Affiliates of
Company hereby agree, jointly and severally, to indemnify and hold harmless each
Indemnitee (as defined in subsection 11.3(b)), from and against any loss,
liability, expense, damage or injury suffered or sustained by reason of any
acts, omissions or alleged acts or omissions arising out of, or relating to,
activities of the Master Servicer and the Servicers which are Affiliates of the
Company pursuant to the Transactions, including but not limited to any judgment,
award, settlement, reasonable attorneys' fees and other reasonable costs or
expenses incurred in connection with the defense of any actual or threatened
action, proceeding or claim; provided, that the Master Servicer and the
                             --------                                  
Servicers which are Affiliates of the Company shall not so indemnify any
Indemnitee for any loss, liability, damage, injury, cost or expense of such
Indemnitee (i) arising solely from a default by an Obligor with respect to any
Receivable (other than arising out of (A) any discharge, claim, offset or
defense (other than discharge in bankruptcy of the Obligor) of the Obligor to
the payment of any Purchased Receivable arising
<PAGE>
 
                                                                              61

from the actions of the Master Servicer or Servicer which is an Affiliate of the
Company (including, without limitation, a defense based on such Purchased
Receivable's not being a legal, valid and binding obligation of such Obligor
enforceable against it in accordance with its terms), or (B) a failure by the
Master Servicer or Servicer which is an Affiliate of the Company to perform its
duties or obligations under this Agreement), or (ii) to the extent that such
liability, cost or expense arises from the gross negligence, bad faith or wilful
misconduct of such Indemnitee or any other Indemnitee. The provisions of this
indemnity shall run directly to, and be enforceable by, an injured party and
shall survive the termination of this Agreement and the resignation of the
Master Servicer or any Servicer which is an Affiliate of the Company.

          (c)  The Servicers, the Master Servicer and the Company each hereby
irrevocably grant to the Administrative Agent an irrevocable power of attorney,
with full power of substitution, coupled with an interest, to take in the name
of the Master Servicer, such Servicer or the Company or in its own name at any
time after the occurrence of a Complete Servicing Transfer all steps necessary
or advisable to endorse, negotiate or otherwise realize on any writing or other
right of any kind held or owned by the Master Servicer, such Servicer or the
Company or transmitted to or received by the Administrative Agent as payment on
account or otherwise in respect of any Receivable.

          (d)  Upon the occurrence and during the continuance of any Servicer
Event of Default, the Administrative Agent shall, at the request of the Required
Participants, by giving two Business Days' notice in writing to the Master
Servicer (a "Transfer Notice"), terminate any or all Servicer or Master Servicer
administrative, servicing and collection functions provided for herein as to any
or all of the Servicers and the Master Servicer (the termination of all such
functions with respect to all Servicers and the Master Servicer being referred
to as a "Complete Servicing Transfer" and any other such termination being
referred to as a "Partial Servicing Transfer").  Upon the occurrence of either a
Partial Servicing Transfer or a Complete Servicing Transfer, without limitation,
(i) a designee of the Required Participants (for purposes of paragraphs (d)
through (e) of this subsection 12.2, the term "Substitute Servicer" means such
designee, as appropriate) shall administer the administrative, servicing and
collection functions of each terminated Servicer and/or the Master Servicer, as
the case may be (each, a "Transferring Servicer") (in the case of a Partial
Servicing Transfer) or all Servicers and the Master Servicer (in the case of a
Complete Servicing Transfer) in any manner it deems fit (which may include
notifying any Obligor of the assignment to the Participants of the interest in
the affected Receivables and/or directing any Obligor to make all payments in
respect of the affected Receivables in the name of the Substitute Servicer);
provided, that the Substitute Servicer shall furnish or cause to be furnished to
- --------                                                                        
the Company such information as such Company needs to perform its obligations
under this Agreement, and the Company may, without independent investigation,
rely on such information for all purposes of this Agreement and (ii) the
Company, each Transferring Servicer (in the case of a Partial Servicing
Transfer) or each Servicer and the Master Servicer (in the case of a Complete
Servicing Transfer) shall, at its own expense, (x) if so

                                                                              62

requested by the Substitute Servicer, endorse each instrument, if any,
evidencing any Receivable to the Substitute Servicer in such manner as the
Substitute Servicer shall reasonably direct and (y) perform, or cause to be
performed by any Person involved in administrative, servicing or collection
functions on behalf of or under the direction of each Transferring Servicer (in
the case of a Partial Servicing Transfer) or each Servicer and the Master
Servicer (in the case of a Complete Servicing Transfer) or the Company, any and
all acts, any and all documents as, in each case, may be reasonably requested by
the Substitute Servicer in order to effect the purposes of this Agreement and
the transfer and assignment of the Participating Interest and to perfect and
protect the ownership interest of the Participants in the Receivables and the
Related Property. Each Servicer agrees to serve as a Substitute Servicer if so
designated by the Required Participants at any time and from time to time. Upon
the occurrence of a Partial Servicing Transfer or a Complete Servicing Transfer,
each Transferring Servicer (in the case of a Partial Servicing Transfer) or each
Servicer and the Master Servicer (in the case of a Complete Servicing Transfer)
shall promptly transfer its electronic records relating to its Receivables to
the Substitute Servicer in such electronic form as the Substitute Servicer may
reasonably request and shall promptly transfer to the Substitute Servicer all
other records, correspondence and documents necessary for the continued
servicing of such Receivables in the manner and at such times as the Substitute
Servicer shall reasonably request; provided, that to the extent that such
                                   --------
Transferring Servicer or such Servicer and the Master Servicer, as the case may
be, is required to have, as a result of a continuing relationship with the
related Obligors, access to any such records in respect of its Receivables, the
Substitute Servicer shall allow such Transferring Servicer or such Servicer and
the Master Servicer, as the case may be, to have reasonable access to such
records upon reasonable advance notice and so long as such access shall not
disrupt or otherwise interfere with the Substitute Servicer's use of such
records in performing its duties hereunder. Upon the occurrence of a Partial
Servicing Transfer or a Complete Servicing Transfer, each Transferring Servicer
(in the case of a Partial Servicing Transfer) or each Servicer and the Master
Servicer (in the case of a Complete Servicing Transfer) shall promptly transfer
to the Administrative Agent non-exclusive licenses to use any computer programs,
material tapes, disks, cassettes and data necessary or advisable to permit the
collection of Receivables by a Servicer without the participation of any Seller
or the Company or, to the extent that such transfer would violate legal
restrictions applicable thereto, shall establish other arrangements to use any
computer programs, material tapes, disks, cassettes and data necessary or
advisable to permit the collection of Receivables by a Servicer without the
participation of any Seller or the Company.

          (e)  Each Transferring Servicer (in the case of a Partial Servicing
Transfer) or each Servicer and the Master Servicer (in the case of a Complete
Servicing Transfer) and the Company shall each execute and deliver such
additional documents and shall take such further action as the Substitute
Servicer may reasonably request to effect or evidence the transfer of servicing

                                                                              63

necessary or appropriate to enable the Substitute Servicer, on behalf of the
Participants, to endorse for payment any check, draft or other instrument
delivered in payment of any amount under or in respect of an affected
Receivable. If any Servicer, the Master Servicer or the Company receives any
cash or checks, drafts or other instruments for the payment of money on account
or otherwise in respect of the Purchased Receivables, such Servicer, the Master
Servicer or the Company shall segregate such cash and other items, hold such
cash and other items in trust for the benefit of the Participants and cause such
cash and other items (properly endorsed, where required, so that such items may
be collected by the Substitute Servicer) to be transmitted or delivered to the
Substitute Servicer for deposit in the Concentration Account within one Business
Day after the date any such cash or other item shall have been identified and
segregated by such Servicer, the Master Servicer or the Company as being on
account of a Purchased Receivable.

          12.3  Maintenance of Records.  Each Servicer and the Master Servicer
                ----------------------                                        
will hold in trust for the Participants at the office of such Servicer or Master
Servicer set forth in Schedule 2 such books of account and other records as it
currently maintains for its own purposes in the ordinary course of its business,
which books of account and other records shall be in a form reasonably
satisfactory to the Administrative Agent to determine at any time the status of
the Receivables and all collections and payments in respect thereof (including,
without limitation, an ability to recreate records evidencing Receivables in the
event of the destruction of the originals thereof).  The Administrative Agent
may at any time and from time to time upon reasonable prior notice during the
regular business hours of any Servicer or the Master Servicer inspect, audit,
check and make abstracts from the books, accounts, records, or other papers of
such Servicer or the Master Servicer pertaining to the Receivables.  From time
to time upon the written request of the Administrative Agent, which request
shall be promptly made upon a request therefor to the Administrative Agent by
any Participant, each Servicer or the Master Servicer, at its own expense, will
as promptly as is practicable deliver to the Administrative Agent a schedule of
the Receivables indicating as to each Receivables information as to the Obligor
thereon, the unpaid balance thereof, the amount and delinquency of any
Receivable that is past due and such other information as the Administrative
Agent may reasonably request.  Upon the written request of the Administrative
Agent, which request may only be made at any time after a Partial Servicing
Transfer or a Complete Servicing Transfer, each terminated Servicer and the
Master Servicer, at its own expense, will deliver to the Administrative Agent,
or to any agent selected by the Administrative Agent, any records pertaining
thereto and evidence thereof as the Administrative Agent may deem necessary to
enable it to enforce the Participants' rights thereunder; provided, that to the
                                                          --------             
extent that such terminated Servicer or the Master Servicer is required to have,
as a result of a continuing relationship with the related Obligors, access to
any such records in respect of its Receivables, the Administrative Agent (or the
agent selected by it) shall allow such terminated Servicer or the Master
Servicer to have reasonable access to such records upon reasonable advance
notice and so long as such access shall not disrupt or otherwise interfere with
the Administrative Agent's (or its agent's) use of such records in performing
its duties hereunder.  Upon the expiration of the

                                                                              64

Commitment Period, the reduction of the Net Investment to zero and the payment
in full of all amounts owing to the Participants and the Administrative Agent
hereunder, the Administrative Agent will promptly return to the Servicers and
the Master Servicer any such records delivered to the Administrative Agent or
its agent.

          12.4  Rebates, Adjustments, Returns and Reductions; Modifications.
                -----------------------------------------------------------  
From time to time the Master Servicer or a Servicer may make Adjustments to
Receivables in accordance with subsection 12.6(o).  If the Master Servicer or
any Servicer makes any Adjustment, then, in any such case, the amount of
Receivables will be automatically reduced by the principal amount of such
Adjustment.  Any Adjustment shall be made on the Business Day on which such
adjustment obligation arises or is identified.  In addition, (and without
limiting the obligations of the Sellers under the Receivables Sale Agreement to
make Seller Adjustment Payment in respect thereof) if, after giving effect to
any such Adjustment, the Invested Percentage would exceed the Maximum Invested
Percentage, the Company shall pay to the Administrative Agent, for the account
of the Participants, an amount equal to the lesser of (i) the dollar amount of
such Adjustment and (ii) the amount necessary to cause the Invested Percentage
to equal the Maximum Invested Percentage (the amount of each such payment is
referred to herein as an "Adjustment Payment"). Such Adjustment Payment shall be
treated as a Collection and shall be distributed in accordance with the
applicable provisions of subsection 2.7.

          12.5  Daily Reports; Settlement Statements.  (a)  On each Business Day
                ------------------------------------                            
the Company and Master Servicer, jointly and severally, agree to prepare a
written report (the "Daily Report") in the form of Exhibit F, with such changes
as may be agreed upon by the Administrative Agent, the Company and the Master
Servicer, setting forth for the preceding Business Day (the "Reporting Day")
total Collections, the amount of Receivables created and the Aggregate Eligible
Receivables, and such other information as the Administrative Agent may request,
which report shall show such information for all Sellers as well as only with
respect to Sellers whose Effective Date has occurred.  The Master Servicer shall
complete such Daily Report and deliver it to the Administrative Agent prior to
12:00 Noon (New York City time) on the second Business Day following the
Reporting Day.  Each Daily Report shall be transmitted by telecopy to the
Administrative Agent at the telecopy number specified in subsection 11.9.

          (b)   Not later than five Business Days prior to each Settlement Date
until the Participating Interest of the Participants in the Receivables has been
reduced to zero and the Commitments of the Participants hereunder have been
terminated, the Company and the Master Servicer, jointly and severally, agree to
submit to the Administrative Agent a statement (hereinafter, a "Settlement
Statement"), substantially in the form attached hereto as Exhibit C or such
other form as may be acceptable to the Administrative Agent, which statement
shall show such information for all Sellers as well as only with respect to
Sellers whose Effective Date has occurred. Promptly upon receipt thereof, the
Administrative Agent shall forward a copy of each Settlement Statement to each
Participant.

the Master Servicer will deliver to the Administrative Agent and each
Participant a certificate of a Responsible Officer of the Master Servicer
stating that (a) a review of the activities of the Master Servicer and each
Servicer and its performance hereunder during such fiscal quarter was made under
the supervision of such Responsible Officer, (b) to the best knowledge of such
Responsible Officer, based on such review, the Master Servicer and each Servicer
has accurately and correctly performed its obligations hereunder in all material
respects throughout such quarter, or, if there has been a material default in
the performance of any such obligation, specifying the nature and status of each
such default and (c) to the best knowledge of such Responsible Officer, based on
such review, each Daily Report and Settlement Statement was accurate and correct
in all material respects, except as specified in such certificate.

               ----------------------------------

     Adverse Change.  (i)  The Master Servicer has heretofore furnished to the
     --------------                                                           
     Participants its consolidated balance sheet and statements of income,
     stockholders equity and cash flows (A) as of and for the fiscal year ended
     December 31, 1996, reported on by Arthur Andersen LLP, independent public
     accountants, and (B) as of and for the fiscal quarter and the portion of
     the fiscal year ended September 30, 1997, signed by its chief financial
     officer.  Such financial statements present fairly, in all material
     respects, the financial position and results of operations and cash flows
     of the Master Servicer and its consolidated Subsidiaries as of such dates
     and for such periods in accordance with GAAP, subject to year-end audit
     adjustments and the absence of footnotes in the case of the statements
     referred to in clause (B) above.  As of the Commencement Date, the Master
     Servicer and its Subsidiaries do not have any material Guarantee
     obligations, contingent liabilities and liabilities for taxes, or any long-
     term leases or unusual forward or long-term commitments, including, without
     limitation, any material interest rate or foreign currency swap or exchange
     transaction or other obligation in respect of derivatives, that have
     materially changes from those reflected, individually or in the aggregate,
     in either (i) the most recent financial statements referred to in this
     paragraph or (ii) filings made by the Master Servicer with the SEC that
     were publicly available prior to the Commencement Date.  During the period
     from December 31, 1996 to and including the date hereof there has been no
     disposition by the Master Servicer or any of its Subsidiaries of any
     material part of their business or property (determined on a consolidated
     basis with respect to the Master Servicer and its Subsidiaries), other than
     dispositions disclosed in filings made with the SEC that were publicly
     available prior to the Commencement Date.  The Master Servicer has
     disclosed to the Participants all agreements, instruments and corporate or
     other restrictions to which it or any of its Subsidiaries is subject, and
     all other matters known to it, that, individually or in the aggregate,
     could reasonably be expected to result in a Material Adverse Effect.

          (ii) None of the reports, financial statements, certificates or other

of the representations and warranties contained in this subsection 12.6 shall be
deemed to have been made by the Master Servicer or such Servicer, as the case
may be, (x) as of the Commencement Date, and (y) with respect to an Increase in

representation or warranty expressly relates only to a prior date.

          12.7   Acquisition Obligation.  (a)  In the event of any breach of any
                 ----------------------                                         
of the representations, warranties or covenants of the Master Servicer or any
Servicer which is an Affiliate of the Company contained in subsection 12.6(e),
(h), (i), (j), (o), or (p), then upon the earlier to occur of the discovery of
such event by a Responsible Officer of such Person, or receipt by such Person of
written notice of such event given by the Administrative Agent, the outstanding
Principal Amount of Receivables shall be reduced by the Principal Amount of such
Receivables in respect of which such representation or warranty was incorrect or
such covenant was breached; provided, however, that (i) prior to the
                            --------  -------                       
Amortization Period, to the extent that such a reduction would cause the
Invested Percentage to be more than the Maximum Invested Percentage, the Master
Servicer and the Servicers which are Affiliates of the Company, jointly and
severally, agree to acquire such Receivable and any Related Property with
respect thereto on the terms and conditions set forth in paragraph (b) below and
(ii) during the Amortization Period, the Master Servicer and the Servicers which
are Affiliates of the Company, jointly and severally, agree (regardless of which
such Servicer or Master Servicer shall have been responsible for such breach) to
acquire such Receivable and any Related Property with respect thereto on the
terms and conditions set forth in paragraph (b) below.  In the event of any
breach of any of the representations, warranties or covenants of the Master
Servicer or any Servicer which is not an Affiliate of the Company contained in
subsection 12.6(e), (h), (i), (j), (o) or (p), then upon the earlier to occur of
the discovery of such event by such Person, or receipt by such Person of written
notice of such event given by the Administrative Agent, the outstanding
Principal Amount of Receivables shall be reduced by the Principal Amount of such
Receivables in respect of which such representation or warranty was incorrect or
such covenant was breached upon the deposit by the Master Servicer or such
Servicer (which deposit the Master Servicer or such Servicer hereby agrees to
make) into the Collection Account in immediately available funds an amount equal
to the Principal Amount of such Receivable (together with payments pursuant to
paragraph (b), "Servicer Transfer Payments").

          (b)    If any breach of a representation, warranty or covenant by a
Servicer or the Master Servicer which is an Affiliate of the Company which
necessitates the acquisition of a Receivable by the Master Servicer and the
Servicers pursuant to paragraph (a) remains uncured on the day which is 5 days
after discovery or notice of such breach, the Master Servicer and such Servicers
shall acquire such Receivable and any Related Property with respect thereto by
depositing into the Collection Account in immediately available funds on such
5th

Day), an amount equal to (i) prior to an Amortization Period, the lesser of (A)
the amount necessary to cause the Invested Percentage to equal the Maximum
Invested Percentage and (B) the Principal Amount of such Receivable or (ii)
during an Amortization Period, the Principal Amount of such Receivable (also, a
"Servicer Transfer Payment"). Upon deposit of the Servicer Transfer Payment, the
Participants shall automatically and without further action be deemed to sell,
transfer, assign, set-over and otherwise convey to such Person, free and clear
of any Lien created by the Participants but otherwise without recourse,
representation or warranty, all the right, title and interest of the
Participants in and to such Receivable, and all Related Property with respect
thereto; and such retransferred Receivable shall be treated by the Participants
as collected in full as of the date on which it was transferred. The
Administrative Agent shall execute such documents and instruments of transfer or
assignment and take such other actions as shall reasonably be requested by the
Master Servicer to effect the conveyance of such Receivables pursuant to this
subsection 12.7.

          12.8   Obligations Unaffected. The obligations of the Master Servicer,
                 ----------------------

under this Agreement shall not be affected by reason of any invalidity,
illegality or irregularity of any Receivable or any transfer and assignment of a
Receivable.

                 ---------------------

Administrative Agent has approved may become additional Servicers parties hereto
upon execution by each such Subsidiary of an Additional Servicer Supplement.

                 ----------------------------

collected by the Servicers or the Master Servicer or amounts payable pursuant to
subsection 12.4 or 12.7, or otherwise, is not paid by such Servicer or the
Master Servicer, as the case may be, on the relevant Settlement Date or other
relevant date, such amount shall be payable together with interest for each day

     and such failure shall continue unremedied for two consecutive Business
     Days after the Administrative Agent shall have delivered notice thereof to
     such Servicer or the Master Servicer, as the case may be; provided, that if
                                                               --------

     the Master Servicer, the failure to deliver any Daily Report or Settlement

     Default unless such failure continues for longer than the lesser of (x) ten
     consecutive Business Days and (y) the length of such Force Majeure Delay
     (or, if greater, two Business Days) after the Administrative Agent shall
     have delivered notice of such failure to the Company, or (2) shall fail to
     make any payment reflected in such Daily Report or Settlement Statement as
     being required to be made by it thereunder on the date such report or

     fail to pay any amount required to be paid by it hereunder (other than
     those specified in paragraph (a) of this subsection 12.11) within five
     Business Days after the date when due;

          (c)  any Servicer or the Master Servicer, as the case may be, shall
     fail to observe or perform any covenant or agreement applicable to it
     contained herein (other than as specified in subsections (a) and (b) of
     this subsection 12.11); provided, that, except in the case of any failure

     to observe or perform any covenant contained in subsection 12.6(q), no such
     failure shall constitute a Servicer Event of Default under this paragraph
     (c) unless such failure shall continue unremedied for a period of 30
     consecutive days after notice thereof from the Administrative Agent, the
     Required Participants or the Company; provided, that a Servicer Event of

     shall prove to have been false or misleading in any material respect on or
     as of the date made or deemed made; provided, that a Servicer Event of
                                         --------

November 25, 1997

Mr. Herbert A. Getz

Re: Loan and Indemnification Agreement

Dear Herb:

     You currently hold options to acquire 240,000 shares of the common stock of
Wheelabrator Technologies Inc. ("WTI") at an option exercise price of $8.9031 
per share, under the 1986 Stock Plan for Executive Employees of Wheelabrator 
Technologies Inc. and its Subsidiaries (the "WTI 1986 Plan"). These grants of 
stock options expire on November 30, 1997. Ordinarily, you could exercise these 
options and sell the shares of common stock of WTI that you would receive (the 
"WTI Option Shares") and benefit from the increase in the price of WTI's common 
stock that has resulted from, among other things, the pending offer by Waste 
Management, Inc. (the "Company") to acquire all of the publicly held shares of 
common stock of WTI (the "WTI Offer"). However, under the Company's securities 
trading policy, you have been denied the ability to sell the WTI Option Shares 
while the negotiation of the WTI Offer is pending. As a result of this 
unforeseeable conjunction of the impending expiration of the WTI options, the 
Company's pending negotiations with WTI, and the Company's securities trading 
policy, the Board of Directors of the Company has determined that it would be 
appropriate to preserve for you the ability to benefit from the value of your 
WTI options and to hold you harmless from the adverse consequences of the 
Company's requirement that you comply with the Company's securities trading 
policy. Accordingly, the Board of Directors has authorized me, on behalf of the 
Company, to enter into an agreement with you upon the following terms and 
conditions.

     Upon the terms of the Promissory Note and Security Agreement attached 
hereto as Exhibit 1 (the "Note"), the Company will loan you $2,136,744, the 
aggregate exercise price of your WTI options, to be used solely for payment of 
the aggregate exercise price of your WTI options. This loan will be fully 
collaterized by a security interest in such number of WTI Option Shares that, 
valued at $15.375, yesterday's closing price, shall be equal to the principal 
amount of the loan. You will also surrender a sufficient number of shares of WTI
common stock to WTI to satisfy applicable federal and state income tax 
withholding requirements, pursuant to the terms of the WTI 1986 Plan. To hold 
you harmless from the risk that the Company's securities trading policy would 
deny you the ability to sell the WTI Option Shares for at least the amount of 
the Company's lowest publicly-disclosed offer price in the WTI Offer (the 
"Lowest Offer Price"), the Company hereby agrees to indemnify you to the extent

Executive.

     2.  TERM.  Subject only to the provisions hereof set forth in Section 7,
the term of this Agreement (herein the "Term") shall be for a period beginning

Agreement shall be renewed for a period ending on the earlier of (i) the date
two (2) 
<PAGE>
 
years from such March 10, or (ii) the date of the Executive's 62nd
birthday on which birthday this Agreement shall terminate unless earlier

     3.  COMPENSATION.  During the Term, the Executive's salary shall be payable

initially be $350,000 per annum and thereafter be established by either the
Compensation and Stock Option Committee of the Board of Directors of the Company
(subject to approval by the full Board) or, in the event Executive is not among
the Company officers whose compensation is subject to review by the Compensation
and Stock Option Committee of the Board, by the Executive Committee of the
Company (the applicable committee being referred to herein as the "Committee")
and all adjustments thereto and all aspects of the Executive's incentive or
performance compensation shall be established by the Committee in its sole
discretion.  In the event there is no Committee in existence at any time, the

Company.  During the Term, the Executive shall also receive such benefits and
perquisites (the "Benefits") which are made available to similarly positioned
executives of the Employer including, without limitation, incentive
compensation, loans, awards, insurance, stock options, stock purchase plans,
benefits from qualified plans or non-qualified plans or other benefit plans now
or hereafter existing which are adopted by the Employer for the benefit of its
employees generally and for the benefit of the Employer's officers, all such
Benefits to be provided in such amounts as may be determined from time to time
by the Committee in its discretion.

full time, attention and energy to the business of the Employer and the
Executive shall not be engaged in any other business activity pursued for gain,
profit or other pecuniary advantage which activity interferes with the
Executive's duties and responsibilities provided for herein.

     5.   NON-COMPETITION AND NON-SOLICITATION.  Executive agrees that:
          ------------------------------------                          

          (a) During the Term and for a period of one year thereafter or during
any Severance Period, if longer (the "Restricted Period"), Executive agrees that
he will not (without the written consent of the Chief Executive Officer) engage
directly or indirectly in any business within the United States (financially as
an investor or lender or as an employee, director, officer, partner, independent
contractor, consultant or owner or in any other capacity calling for the
rendition of personal services or acts of management, operation or control)
which is directly competitive with the business at any time during the Term
conducted by the Company or any of its subsidiaries or Affiliates as defined
below.  Notwithstanding the foregoing, Executive shall be entitled to own
securities of any corporation conducting a business competitive with the
business of the Company or any of its subsidiaries or Affiliates so long as the
securities of such corporation are listed on a national securities exchange and
the securities owned directly or indirectly by Executive do not represent more
than two percent (2%) of any class of the outstanding securities of such
company.

          (b) During the Restricted Period, in addition to the obligations
pursuant to Subsection 5(a), Executive agrees that neither he nor any business
in which he engages directly or 

                                       2
<PAGE>
 
indirectly will (i) directly or indirectly induce any customers of the Company
or of corporations or businesses which directly or indirectly control or are
controlled by or under common control with the Company ("Affiliates") to
patronize any business similar to that of the Company, (ii) canvass, solicit or
accept any similar business from any customer of the Company or any Affiliates,
(iii) directly or indirectly request or advise any customer of the Company or
Affiliates to withdraw, curtail or cancel such customer's business with the
Company or Affiliates, (iv) directly or indirectly disclose to any other person,
firm or corporation the names or addresses of any of the customers of the
Company or Affiliates, or (v) compete with the Company or Affiliates in
acquiring or merging with any other business or acquiring the assets of such
other business.

          (c) During the Restricted Period, in addition to the obligations
pursuant to Subsections 5(a) and 5(b), Executive agrees that neither he nor any
business in which he engages directly or indirectly will (i) hire or attempt to
hire any employee of the Company or its Affiliates nor (ii) directly or
indirectly encourage any employee of the Company or its Affiliates to terminate
employment with the Company or its Affiliates.  Notwithstanding the foregoing,
it shall not be deemed a violation of this subsection if a business which
employs Executive hires or attempts to hire an employee of the Affiliates and
Executive has no knowledge of, control over or involvement with such
solicitation.

          (d) In the event that any of the provisions of this Section 5 should
ever be deemed to exceed the time, geographic or occupational limitations
permitted by applicable laws, then such provisions shall be and are hereby
reformed to the maximum time, geographic or occupational limitations permitted
by law.

      6.  CONFIDENTIAL INFORMATION.  The Executive acknowledges that in his
employment he is or will be making use of, acquiring or adding to the Employer's
and Company's confidential information which includes, but is not limited to,
memoranda and other materials or records of a proprietary nature and records and
policy matters relating to finance, personnel, management and operations.
Therefore, in order to protect the Employer's and Company's confidential
information and to protect other employees who depend on the Employer and
Company for regular employment, the Executive agrees that he will not in any way
utilize any of said confidential information except in connection with his
employment by the Employer, and except in connection with the business of the
Employer and Company he will not copy, reproduce or take with him the original
or any copies of said confidential information and will not disclose any of said
confidential information to anyone.

      7.  TERMINATION.
          ----------- 

          (a) Death or Disability. If the Executive should become physically
or mentally disabled and unable to perform his duties hereunder for a continuous
period in excess of ninety (90) days (in the reasonable opinion of the
Committee), or if the Executive should die while an employee of the Employer,
this Agreement and Executive's employment with the Employer shall immediately
terminate.

                                       3
<PAGE>
 
          (b) Termination by the Employer for Cause.  The following events shall
create in the Employer a right to terminate the Executive's employment under
this Agreement prior to the expiration of the Term: (i) the commission of fraud,
embezzlement or theft by the Executive in connection with the Executive's
duties; (ii) the intentional wrongful damage to property of the Company, the
Employer and/or their Affiliates by the Executive; (iii) the intentional
wrongful disclosure by the Executive of any secret process or confidential
information of the Company, the Employer and/or their Affiliates; or (iv) the
violation of the Executive's non-disclosure, non-solicitation and non-
competition covenants set forth in Sections 5 and 6.  In the event of such a
Termination for cause pursuant to this Subsection, all of the obligations of the
Employer and the Company under this Agreement shall immediately terminate.

          (c) Other Termination by Employer. In the event the Employer shall
elect to terminate Executive's employment for any reason other than those
specified in Subsection 7(a) or 7(b), it shall provide written notice of such
termination to Executive. In the event that there occurs without the written
consent of the Executive:

          (i)    a change in the Executive's duties, title or responsibilities,
                 or a change in the Executive's reporting relationships, either
                 of which results in or reflects a diminution of the scope or
                 importance of the Executive's duties and responsibilities;

          (ii)   a reduction in the Executive's then current annual base salary
                 (other than as part of reductions in annual base salary
                 affecting the Employer's officers generally);

          (iii)  a reduction in the level of benefits available or awarded under
                 employee and officer benefit plans and programs, including, but
                 not limited to annual and long-term incentive and stock-based
                 plans and programs (other than as part of reductions in such
                 benefit plans or programs affecting the Employer's officers
                 generally);

          (iv)   a relocation of Executive's primary employment location to a
                 location which is more than 50 miles from his current location;
                 or

          (v)    the Company terminates the automatic renewal provision of this
                 Agreement by providing Executive with 30 days' prior written
                 notice as provided in Section 2 hereof

     then Executive may deliver written notice of termination of his employment
     to the Company within three months of such event (which notice shall be
     effective even if such three months expire after the end of the Term). In
     the event of notice being given by the Employer or Executive under this
     Subsection 7(c) within one year of Executive's initial employment with the
     Employer, and subject to the execution and delivery by Executive to the
     Company of the release described in Section 10 hereof, the Company shall
     provide 

                                       4
<PAGE>
 
     Executive with the severance compensation and benefits set forth in
     (u), (w), (x), (y), and (z) below.  In the event of notice being given by
     the Employer or Executive under this Subsection 7(c) after one year of
     Executive's initial employment with the Employer, subject to the execution
     and delivery by Executive to the Company of the release described in
     Section 10 hereof, the Company shall provide Executive with severance
     compensation and benefits set forth in (u)-(z) below:
     
          (u) Executive shall receive an amount equal to his then current base
          salary for two years, payable at intervals not less frequently than
          monthly over a period of two years following the end of the Term (such
          period of payment to be referred to herein as the "Severance Period");

          (v) with respect to any participation rights in the Company's annual
          or long-term incentive plans which have been awarded to Executive
          prior to the end of the Term, Executive shall be entitled to receive a
          prorated award under any such plan, payable if and when awards are
          paid to other similarly positioned officers of the Employer, such
          proration to be determined by dividing the number of whole or partial
          months the Executive is employed during the incentive compensation
          performance period by the total number of months in the incentive
          compensation performance period;

          (w) with respect to Executive's stock options, the exercisability of
          Executive's outstanding stock options shall be accelerated, and such
          options shall remain exercisable during the Severance Period (unless
          they shall otherwise expire earlier by their terms) and such options
          shall otherwise be treated in accordance with the terms of their
          respective grants;

          (x) the Executive's medical, dental and vision Benefits shall be
          continued on the same basis as offered to active salaried employees
          for the Severance Period or until such earlier time as the Executive
          becomes employed and eligible for such benefits under a plan of the
          new employer, and continuation coverage under COBRA shall commence at
          the end of the Severance Period; and

          (y) credit for vesting and benefit service under the Company's
          Supplemental Executive Retirement Plan shall be provided to Executive
          for the Severance Period; and

          (z) all other Benefits shall be paid or continued only to the extent
          the terms thereof provide for payment or continuation following the
          termination of employment.

                                       5
<PAGE>
 
The foregoing shall be in lieu of all salary, bonuses or incentive or
performance based compensation for the remainder of the Term.  If Executive
should die during the Severance Period, any remaining severance payments shall
be made to Executive's surviving spouse or, if none, to his estate.

     (d) Voluntary Termination. If during the Term the Executive should
voluntarily terminate his employment with the Employer for any reason, including
retirement, other than as described in Subsection 7(c) hereof, the obligations
of the Employer and the Company under this Agreement shall terminate forthwith,
other than obligations to (i) pay the Executive's base salary to the date of
voluntary termination, (ii) pay all incentive compensation earned by the
Executive for performance periods which are completed prior to the date of
voluntary termination, at such times and on the same basis amounts as such
incentive compensation becomes payable to other executives of the Employer and
(iii) pay or make available to the Executive all Benefits which by their terms
or under applicable law survive the voluntary termination of the Executive's
employment; and the Executive shall remain bound by his non-disclosure, non-
solicitation and non-competition covenants set forth in Sections 5 and 6 hereof.
The exercisability of the Executive's outstanding stock options shall be treated
in accordance with the terms of their respective grants or awards, except that
in the case of retirement on or after age 62, the Company will recommend to the
Compensation and Stock Option Committee of the Board of Directors of the Company
that the exercisability of Executive's outstanding stock options be accelerated.

     8.  ELECTION TO EXTEND SEVERANCE PERIOD.  Notwithstanding anything in
Subsection 7(c) to the contrary, the Executive may make an irrevocable written
election, within 30 days of receipt or delivery of the written termination
notice provided for in Subsection 7(c), that would extend the time period during
which the base salary is to be paid under Subsection 7(c) for one additional
year.  The total amount of base salary that is to be paid under Subsection 7(c)
will not be affected by this election.  If such election is made, the term
"Severance Period" will be deemed to refer to such extended payment period.

     9.  EXCISE TAX.  In the event that an excise tax ("Excise Tax") is imposed 
on Executive under Section 4999 of the Internal Revenue Code (or any successor
provision of like import) on the payments due under Subsection 7(c)
(collectively, the "Payments"), Executive shall be paid an additional amount
("Gross Up") no later than 30 days prior to the date such Excise Tax is due,
such that the net amount retained by Executive after deduction of the Excise Tax
on the Payments and any federal and state income taxes on the Payments and the
Gross Up shall be equal to the Payments. For purposes of determining the Gross
Up, Executive shall be deemed to pay federal and state income taxes at the
highest marginal rate of taxation in the calendar year in which the Payments or
Gross Up is to be made. The opinion of whether such Excise Tax is payable and
the amount thereof shall be based upon a "substantial authority opinion" of tax
counsel selected by the Company and reasonably acceptable to Executive. If such
opinion is not finally accepted by the IRS upon audit, then appropriate
adjustments shall be computed (with Gross Up) by tax counsel based upon the
final amount of Excise Tax so

                                       6
<PAGE>
 
determined.  The amount shall be paid by the appropriate party in one lump cash
sum within 30 days of such computation.

     10.  GENERAL RELEASE AND COOPERATION AGREEMENT. Notwithstanding anything in
Subsection 7(c) or Section 9 to the contrary and in consideration therefor,
severance benefits and the Gross Up thereunder shall only become payable by the
Company if the Executive executes and delivers to the Company a General Release
and Cooperation Agreement on or after the date of written notice of termination
of Executive's employment or prior to the date the Gross Up is paid, as
applicable, and in substantially the form attached as Exhibit A hereto.

     11.  NOTICES.  Any notice required or permitted to be given under this
Agreement shall be in writing and shall be deemed to have been given when
deposited in the U.S. mail in a registered, postage prepaid envelope addressed:
If to the Executive, at his address set forth below or such other address as
Executive may direct, and if to the Company, c/o Chief Executive Officer, Waste
Management, Inc., 3003 Butterfield Road, Oak Brook, Illinois 60523, with a copy
to the General Counsel, Waste Management, Inc., at the same address.

     12.  ASSIGNMENT. The Executive may not assign his obligations hereunder.
The rights of the Executive and the rights and obligations of the Company
hereunder shall inure to the benefit of and shall be binding upon their
respective heirs, personal representatives, successors and assigns.
 
     13.  MISCELLANEOUS.
          ------------- 
 
          (a) This Agreement shall be subject to and governed by the laws of the
State of Illinois.

          (b) Failure to insist upon strict compliance with any provisions
hereof shall not be deemed a waiver of such provisions or any other provision
hereof.

          (c) This Agreement may not be modified except by an agreement in
writing executed by the parties hereto.

          (d) The invalidity or unenforceability of any provision hereof shall
not affect the validity or enforceability of any other provision.

          (e) This Agreement shall supersede any and all prior employment
agreements or understandings, written or oral, with Executive.

               plans and programs (other than as part of reductions in such
               benefit plans or programs affecting the Employer's officers
               generally);

        (iv)   a relocation of Executive's primary employment location to a
               location which is more than 50 miles from his current location;

described in Section 9 hereof, the Company shall provide Executive with
severance compensation and benefits as follows:

     (t) Executive shall receive an amount equal to his then current base salary
     for two years, payable at intervals not less frequently than monthly over a

     (u) with respect to any participation rights in the Company's annual or
     long-term incentive plans which have been awarded to Executive prior to the
     end of the Term, Executive shall be entitled to receive a prorated award
     under any such plan, payable if and when awards are paid to other similarly
     positioned officers of the Employer, such proration to be determined by
     dividing the number of whole or partial months the Executive is employed
     during the incentive compensation performance period by the total number of
     months in the incentive compensation performance period;

     (v) with respect to Executive's stock options, the Company will recommend
     to the Compensation and Stock Option Committee of the Board of Directors of
     the Company that the exercisability of Executive's outstanding stock
     options be accelerated, such options shall remain exercisable during the
     Severance Period (unless they shall expire earlier by their terms) and such
     options shall otherwise be treated in accordance with the terms of their
     respective grants;

     (w) the Executive's restricted stock shall be treated in accordance with
     the terms of the Restricted Stock Award Certificate applicable thereto;

     (x) the Executive's medical, dental and vision Benefits shall be continued
     on the same basis as offered to active salaried employees for the Severance
     Period or until such earlier time as the Executive becomes employed and
     eligible for such benefits under a plan of the new employer, and
     continuation coverage under COBRA shall commence at the end of the
     Severance Period; and

     (y) credit for vesting and benefit service under the Company's Supplemental
     Executive Retirement Plan shall be provided to Executive for the Severance
     Period; and
<PAGE>
 
     (z) all other Benefits shall be paid or continued only to the extent the
     terms thereof provide for payment or continuation following the termination
     of employment.

The foregoing shall be in lieu of all salary, bonuses or incentive or
performance based compensation for the remainder of the Term. If Executive
should die during the Severance Period, any remaining severance payments shall
be made to Executive's surviving spouse or, if none, to his estate.

     (d) Voluntary Termination. If during the Term the Executive should
voluntarily terminate his employment with the Employer for any reason, including
retirement, other than as described in Subsection 7(c) hereof, the obligations
of the Employer and the Company under this Agreement shall terminate forthwith,
other than obligations to (i) pay the Executive's base salary to the date of
voluntary termination, (ii) pay all incentive compensation earned by the
Executive for performance periods which are completed prior to the date of
voluntary termination, at such times and on the same basis amounts as such
incentive compensation becomes payable to other executives of the Employer and
(iii) pay or make available to the Executive all Benefits which by their terms
or under applicable law survive the voluntary termination of the Executive's
employment; and the Executive shall remain bound by his non-disclosure, non-
solicitation and non-competition covenants set forth in Sections 5 and 6 hereof.
The exercisability of the Executive's outstanding stock options and the vesting
of the Executive's restricted stock shall be treated in accordance with the
terms of their respective grants or awards, except that in the case of
retirement on or after age 62, the Company will recommend to the Compensation
and Stock Option Committee of the Board of Directors of the Company that the
exercisability of Executive's outstanding stock options be accelerated.

Subsection 7(c) to the contrary, the Executive may make an irrevocable written
election, within 30 days of receipt or delivery of the written termination
notice provided for in Subsection 7(c), that would extend the time period during
which the base salary is to be paid under Subsection 7(c) for one additional
year. The total amount of base salary that is to be paid under Subsection 7(c)
will not be affected by this election. If such election is made, the term
"Severance Period" will be deemed to refer to such extended payment period.

     9. GENERAL RELEASE AND COOPERATION AGREEMENT. Notwithstanding anything in
Subsection 7(c) to the contrary and in consideration therefor, severance
benefits thereunder shall only become payable by the Company if the Executive
executes and delivers to the Company a General Release and Cooperation Agreement

                              W I T N E S S E T H:
                              - - - - - - - - - - 
     WHEREAS, the Executive has previously served and is serving as Area

days' prior written notice to the other, on March 10, 1998 and on each
successive March 10, the Term of this Agreement shall be renewed for a period
ending on the earlier of (i) the date two (2) years from such March 10, or (ii)

established by either the Compensation and Stock Option Committee of the Board
of Directors of the Company (subject to approval by the full Board) or, in the
event Executive is not among the Company officers whose compensation is subject

Executive Committee of the Company (the applicable committee being referred to
herein as the "Committee") and all adjustments thereto and all aspects of the
Executive's incentive or performance compensation shall be established by the
Committee in its sole discretion. In the event there is no Committee in

Executive Officer of the Company. During the Term, the Executive shall also
receive such benefits and perquisites (the "Benefits") which are made available
to similarly positioned executives of the Employer including, without
limitation, incentive compensation, loans, awards, insurance, stock options,
stock purchase plans, benefits from qualified plans or non-qualified plans or

shall not be engaged in any other business activity pursued for gain, profit or
other pecuniary advantage which activity interferes with the Executive's duties
and responsibilities provided for herein.

     5.  NON-COMPETITION AND NON-SOLICITATION.  Executive  agrees that:
         ------------------------------------                          

          (a) During the Term and for a period of one year thereafter or during
any Severance Period, if longer (the "Restricted Period"), Executive agrees that
he will not (without the written consent of the Chairman of the Board) engage
directly or indirectly in any business within the United States (financially as
an investor or lender or as an employee, director, officer, partner, independent
contractor, consultant or owner or in any other capacity calling for the
rendition of personal services or acts of management, operation or control)
which is directly competitive with the business at any time during the
Restricted Period conducted by the Company or any of its subsidiaries or
Affiliates as defined below. Notwithstanding the foregoing, Executive shall be
entitled to own securities of any corporation conducting a business competitive
with the business of the Company or any of its subsidiaries or Affiliates so
long as the securities of such corporation are listed on a national securities
exchange and the securities owned directly or indirectly by Executive do not
represent more than two percent (2%) of any class of the outstanding securities
of such company.

                                       2
<PAGE>
 
          (b) During the Restricted Period, in addition to the obligations
pursuant to Subsection 5(a), Executive agrees that neither he nor any business
in which he engages directly or indirectly will (i) directly or indirectly
induce any customers of the Company or of corporations or businesses which
directly or indirectly control or are controlled by or under common control with
the Company ("Affiliates") to patronize any business similar to that of the
Company, (ii) canvass, solicit or accept any similar business from any customer
of the Company or any Affiliates, (iii) directly or indirectly request or advise
any customer of the Company or Affiliates to withdraw, curtail or cancel such
customer's business with the Company or Affiliates, (iv) directly or indirectly
disclose to any other person, firm or corporation the names or addresses of any
of the customers of the Company or Affiliates, or (v) compete with the Company
or Affiliates in acquiring or merging with any other business or acquiring the
assets of such other business.

          (c) During the Restricted Period, in addition to the obligations
pursuant to Subsections 5(a) and 5(b), Executive agrees that neither he nor any
business in which he engages directly or indirectly will (i) hire or attempt to
hire any employee of the Company or its Affiliates nor (ii) directly or
indirectly encourage any employee of the Company or its Affiliates to terminate
employment with the Company or its Affiliates.  Notwithstanding the foregoing,
it shall not be deemed a violation of this subsection if a business which
employs Executive hires or attempts to hire an employee of the Affiliates and
Executive has no knowledge of, control over or involvement with such
solicitation.

          (d) In the event that any of the provisions of this Section 5 should
ever be deemed to exceed the time, geographic or occupational limitations
permitted by applicable laws, then such provisions shall be and are hereby
reformed to the maximum time, geographic or occupational limitations permitted
by law.

     6.   CONFIDENTIAL INFORMATION.  The Executive acknowledges that in his
employment he is or will be making use of, acquiring or adding to the Employer's
and Company's confidential information which includes, but is not limited to,
memoranda and other materials or records of a proprietary nature and records and
policy matters relating to finance, personnel, management and operations.
Therefore, in order to protect the Employer's and Company's confidential
information and to protect other employees who depend on the Employer and
Company for regular employment, the Executive agrees that he will not in any way
utilize any of said confidential information except in connection with his
employment by the Employer, and except in connection with the business of the
Employer and Company he will not copy, reproduce or take with him the original
or any copies of said confidential information and will not disclose any of said
confidential information to anyone.
  
     7.   TERMINATION.
          ----------- 
  
          (a) Death or Disability.   If the Executive should become physically

this Agreement prior to the expiration of the Term: (i) the commission of fraud,
embezzlement or theft by the Executive in connection with the Executive's
duties; (ii) the intentional wrongful damage to property of the Company, the

information of the Company, the Employer and/or their Affiliates; or (iv) the

termination to Executive. In the event that there occurs without the written
consent of the Executive:

                 change in the Executive's reporting relationships, either of
                 which results in or reflects a diminution of the scope or
                 importance of the Executive's duties and responsibilities;
          
          (ii)   a reduction in the Executive's then current annual base salary
                 (other than as part of reductions in annual base salary
                 affecting the Employer's officers generally);

                 not limited to annual and long-term incentive and stock-based
                 plans and programs (other than as part of reductions in such
                 benefit plans or programs affecting the Employer's officers
                 generally);

          (iv)   a relocation of Executive's primary employment location to a
                 location which is more than 50 miles from his current location;

considers extremely valuable to the continued prosperity of the Company; and

     WHEREAS, the Company wishes to ensure that it will continue to have the
Executive available to perform for the Company and its subsidiaries duties as
Vice President & Controller (North American Operations); and
 
     WHEREAS, the Company and the Executive desire to set forth in this
Agreement the terms, conditions and obligations of the parties with respect to
such employment and this Agreement is intended by the parties to supersede all
previous agreements and understandings, whether written or oral, concerning such
employment.

     NOW, THEREFORE, for and in consideration of the premises and the mutual
covenants contained herein, the parties agree as follows:

     1.  EMPLOYMENT.  The Company or its applicable subsidiary (hereinafter the
"Employer") shall continue to employ the Executive as an employee at will upon
the terms and conditions hereinafter set forth.  The Executive shall perform
such duties and responsibilities for the Employer which are commensurate with
his position as may be assigned him by the Company's Senior Vice President and
Chief Financial Officer and shall serve as a member of the Management Committee
of the Company. The Executive shall report to the Senior Vice President and
Chief Financial Officer of the Company.  Incident to the performance of such
duties, the Executive shall be provided by the Employer with office space,
facilities and secretarial assistance commensurate with that currently being
provided to the Executive.

     2.  TERM.  Subject only to the provisions hereof set forth in Section 7,
the term of this Agreement (herein the "Term") shall be for a period beginning
on the date hereof and ending on March 10, 1999.  Subject to the provisions of
Section 7 hereof, and unless a party gives 30 
<PAGE>
 
days' prior written notice to the other, on March 10, 1998 and on each
successive March 10, the Term of this Agreement shall be renewed for a period
ending on the earlier of (i) the date two (2) years from such March 10, or (ii)
the date of the Executive's 62nd birthday on which birthday this Agreement shall
terminate unless earlier terminated in accordance with the terms hereof.

     3.  COMPENSATION.  During the Term, the Executive's salary shall be payable
at intervals not less often than semi-monthly.  The Executive's salary shall be
established by either the Compensation and Stock Option Committee of the Board
of Directors of the Company (subject to approval by the full Board) or, in the
event Executive is not among the Company officers whose compensation is subject
to review by the Compensation and Stock Option Committee of the Board, by the
Executive Committee of the Company (the applicable committee being referred to
herein as the "Committee") and all adjustments thereto and all aspects of the
Executive's incentive or performance compensation shall be established by the
Committee in its sole discretion.  In the event there is no Committee in
existence at any time, the term Committee shall be deemed to refer to the Chief
Executive Officer of the Company.  During the Term, the Executive shall also
receive such benefits and perquisites (the "Benefits") which are made available
to similarly positioned executives of the Employer including, without
limitation, incentive compensation, loans, awards, insurance, stock options,
stock purchase plans, benefits from qualified plans or non-qualified plans or
other benefit plans now or hereafter existing which are adopted by the Employer
for the benefit of its employees generally and for the benefit of the Employer's
officers, all such Benefits to be provided in such amounts as may be determined
from time to time by the Committee in its discretion.

     4.  EXTENT OF SERVICE.  During the Term, the Executive shall devote his
full time, attention and energy to the business of the Employer and the
Executive shall not be engaged in any other business activity pursued for gain,
profit or other pecuniary advantage which activity interferes with the
Executive's duties and responsibilities provided for herein.

     5.   NON-COMPETITION AND NON-SOLICITATION.  Executive agrees that:
          ------------------------------------                          

          (a) During the Term and for a period of one year thereafter or during
any Severance Period, if longer (the "Restricted Period"), Executive agrees that
he will not (without the written consent of the Chairman of the Board) engage
directly or indirectly in any business within the United States (financially as
an investor or lender or as an employee, director, officer, partner, independent
contractor, consultant or owner or in any other capacity calling for the
rendition of personal services or acts of management, operation or control)
which is directly competitive with the business at any time during the
Restricted Period conducted by the Company or any of its subsidiaries or
Affiliates as defined below.  Notwithstanding the foregoing, Executive shall be
entitled to own securities of any corporation conducting a business competitive
with the business of the Company or any of its subsidiaries or Affiliates so
long as the securities of such corporation are listed on a national securities
exchange and the securities owned directly or indirectly by Executive do not
represent more than two percent (2%) of any class of the outstanding securities
of such company.


                                       2
<PAGE>
 
          (b) During the Restricted Period, in addition to the obligations
pursuant to Subsection 5(a), Executive agrees that neither he nor any business
in which he engages directly or indirectly will (i) directly or indirectly
induce any customers of the Company or of corporations or businesses which
directly or indirectly control or are controlled by or under common control with
the Company ("Affiliates") to patronize any business similar to that of the
Company, (ii) canvass, solicit or accept any similar business from any customer
of the Company or any Affiliates, (iii) directly or indirectly request or advise
any customer of the Company or Affiliates to withdraw, curtail or cancel such
customer's business with the Company or Affiliates, (iv) directly or indirectly
disclose to any other person, firm or corporation the names or addresses of any
of the customers of the Company or Affiliates, or (v) compete with the Company
or Affiliates in acquiring or merging with any other business or acquiring the
assets of such other business.

          (c) During the Restricted Period, in addition to the obligations
pursuant to Subsections 5(a) and 5(b), Executive agrees that neither he nor any
business in which he engages directly or indirectly will (i) hire or attempt to
hire any employee of the Company or its Affiliates nor (ii) directly or
indirectly encourage any employee of the Company or its Affiliates to terminate
employment with the Company or its Affiliates.  Notwithstanding the foregoing,
it shall not be deemed a violation of this subsection if a business which
employs Executive hires or attempts to hire an employee of the Affiliates and
Executive has no knowledge of, control over or involvement with such
solicitation.

          (d) In the event that any of the provisions of this Section 5 should
ever be deemed to exceed the time, geographic or occupational limitations
permitted by applicable laws, then such provisions shall be and are hereby
reformed to the maximum time, geographic or occupational limitations permitted
by law.

     6.   CONFIDENTIAL INFORMATION.  The Executive acknowledges that in his
employment he is or will be making use of, acquiring or adding to the Employer's
and Company's confidential information which includes, but is not limited to,
memoranda and other materials or records of a proprietary nature and records and
policy matters relating to finance, personnel, management and operations.
Therefore, in order to protect the Employer's and Company's confidential
information and to protect other employees who depend on the Employer and
Company for regular employment, the Executive agrees that he will not in any way
utilize any of said confidential information except in connection with his
employment by the Employer, and except in connection with the business of the
Employer and Company he will not copy, reproduce or take with him the original
or any copies of said confidential information and will not disclose any of said
confidential information to anyone.
  
     7.   TERMINATION.
          ----------- 

          (a) Death or Disability.   If the Executive should become physically
or mentally disabled and unable to perform his duties hereunder for a continuous
period in excess of ninety (90) days (in the reasonable opinion of the
Committee),  or if the Executive should die 


                                       3
<PAGE>
 
while an employee of the Employer, this Agreement and Executive's employment
with the Employer shall immediately terminate.

          (b) Termination by the Employer for Cause. The following events shall
create in the Employer a right to terminate the Executive's employment under
this Agreement prior to the expiration of the Term: (i) the commission of fraud,
embezzlement or theft by the Executive in connection with the Executive's
duties; (ii) the intentional wrongful damage to property of the Company, the
Employer and/or their Affiliates by the Executive; (iii) the intentional
wrongful disclosure by the Executive of any secret process or confidential
information of the Company, the Employer and/or their Affiliates; or (iv) the
violation of the Executive's non-disclosure, non-solicitation and non-
competition covenants set forth in Sections 5 and 6. In the event of such a
Termination for cause pursuant to this Subsection, all of the obligations of the
Employer and the Company under this Agreement shall immediately terminate.

          (c) Other Termination by Employer. In the event the Employer shall
elect to terminate Executive's employment for any reason other than those
specified in Subsection 7(a) or 7(b), it shall provide written notice of such
termination to Executive. In the event that there occurs without the written
consent of the Executive:

          (i)    a change in the Executive's duties or responsibilities, or a
                 change in the Executive's reporting relationships, either of
                 which results in or reflects a diminution of the scope or
                 importance of the Executive's duties and responsibilities;

          (ii)   a reduction in the Executive's then current annual base salary
                 (other than as part of reductions in annual base salary
                 affecting the Employer's officers generally);

          (iii)  a reduction in the level of benefits available or awarded under
                 employee and officer benefit plans and programs, including, but
                 not limited to annual and long-term incentive and stock-based
                 plans and programs (other than as part of reductions in such
                 benefit plans or programs affecting the Employer's officers
                 generally);

          (iv)   a relocation of Executive's primary employment location to a
                 location which is more than 50 miles from his current location;
                 or

          (v)    the Company terminates the automatic renewal provision of this
                 Agreement by providing Executive with 30 days' prior written
                 notice as provided in Section 2 hereof

then Executive may deliver written notice of termination of his employment to
the Company within three months of such event (which notice shall be effective
even if such three months expire after the end of the Term). In either case and
subject to the execution and delivery by

                                       4
<PAGE>
 
Executive to the Company of the release described in Section 9 hereof, the
Company shall provide Executive with severance compensation and benefits as
follows:

     (t) Executive shall receive an amount equal to his then current base salary
     for two years, payable at intervals not less frequently than monthly over a
     period of two years following the end of the Term (such period of payment
     to be referred to herein as the "Severance Period");

     (u) with respect to any participation rights in the Company's annual or
     long-term incentive plans which have been awarded to Executive prior to the
     end of the Term, Executive shall be entitled to receive a prorated award
     under any such plan, payable if and when awards are paid to other similarly
     positioned officers of the Employer, such proration to be determined by
     dividing the number of whole or partial months the Executive is employed
     during the incentive compensation performance period by the total number of
     months in the incentive compensation performance period;

     (v) with respect to Executive's stock options, the Company will recommend
     to the Compensation and Stock Option Committee of the Board of Directors of
     the Company that the exercisability of Executive's outstanding stock
     options be accelerated, such options shall remain exercisable during the
     Severance Period (unless they shall expire earlier by their terms) and such
     options shall otherwise be treated in accordance with the terms of their
     respective grants;

     (w) the Executive's restricted stock shall be treated in accordance with
     the terms of the Restricted Stock Award Certificate applicable thereto;

     (x) the Executive's medical, dental and vision Benefits shall be continued
     on the same basis as offered to active salaried employees for the Severance
     Period or until such earlier time as the Executive becomes employed and
     eligible for such benefits under a plan of the new employer, and
     continuation coverage under COBRA shall commence at the end of the
     Severance Period; and

     (y) credit for vesting and benefit service under the Company's Supplemental
     Executive Retirement Plan shall be provided to Executive for the Severance
     Period; and

     (z) all other Benefits shall be paid or continued only to the extent the
     terms thereof provide for payment or continuation following the termination
     of employment.

The foregoing shall be in lieu of all salary, bonuses or incentive or
performance based compensation for the remainder of the Term. If Executive
should die during the Severance Period, any remaining severance payments shall
be made to Executive's surviving spouse or, if none, to his estate.

                                       5
<PAGE>
 
          (d) Voluntary Termination. If during the Term the Executive should
voluntarily terminate his employment with the Employer for any reason, including
retirement, other than as described in Subsection 7(c) hereof, the obligations
of the Employer and the Company under this Agreement shall terminate forthwith,
other than obligations to (i) pay the Executive's base salary to the date of
voluntary termination, (ii) pay all incentive compensation earned by the
Executive for performance periods which are completed prior to the date of
voluntary termination, at such times and on the same basis amounts as such
incentive compensation becomes payable to other executives of the Employer and
(iii) pay or make available to the Executive all Benefits which by their terms
or under applicable law survive the voluntary termination of the Executive's
employment; and the Executive shall remain bound by his non-disclosure, non-
solicitation and non-competition covenants set forth in Sections 5 and 6 hereof.
The exercisability of the Executive's outstanding stock options and the vesting
of the Executive's restricted stock shall be treated in accordance with the
terms of their respective grants or awards, except that in the case of
retirement on or after age 62, the Company will recommend to the Compensation
and Stock Option Committee of the Board of Directors of the Company that the
exercisability of Executive's outstanding stock options be accelerated.

     8.  ELECTION TO EXTEND SEVERANCE PERIOD. Notwithstanding anything in
Subsection 7(c) to the contrary, the Executive may make an irrevocable written
election, within 30 days of receipt or delivery of the written termination
notice provided for in Subsection 7(c), that would extend the time period during
which the base salary is to be paid under Subsection 7(c) for one additional
year. The total amount of base salary that is to be paid under Subsection 7(c)
will not be affected by this election. If such election is made, the term
"Severance Period" will be deemed to refer to such extended payment period.

     9.  GENERAL RELEASE AND COOPERATION AGREEMENT. Notwithstanding anything in
Subsection 7(c) to the contrary and in consideration therefor, severance
benefits thereunder shall only become payable by the Company if the Executive
executes and delivers to the Company a General Release and Cooperation Agreement
on or after the date of written notice of termination of Executive's employment
and in substantially the form attached as Exhibit A hereto.

     10.  NOTICES. Any notice required or permitted to be given under this
Agreement shall be in writing and shall be deemed to have been given when

     11.  ASSIGNMENT. The Executive may not assign his obligations hereunder.
The rights of the Executive and the rights and obligations of the Company
hereunder shall inure to the benefit of and shall be binding upon their
respective heirs, personal representatives, successors and assigns.

Notes:
(1)  As a result of a comprehensive review, begun in the third quarter of 1997
     the Company determined that certain items of expense were incorrectly
     reported in previously issued financial statements. The Company has
     accordingly restated its financial results for the years 1992 through 1996.
     Stockholders' equity, at December 31, 1991, was restated from $4,133.1
     million to 3,934.5 million. (See Note 2 to Consolidated Financial
     Statements).

(2)  The results for 1992 include a non-taxable gain of $351.1 million (before
     minority interest) resulting from the initial public offering of WM
     International, less $80.6 million of related exit costs, primarily to write
     down international assets not included in WM International, as well as
     special charges of $219.9 million (before tax and minority interest)
     primarily related to writedowns of the Company's medical waste business,
     CWM incinerators in Chicago, Illinois, and Tijuana, Mexico, a former
     subsidiary's investment in its asbestos abatement business, and certain
     costs incurred by the former subsidiary and CWM related to the formation of
     Rust.

(3)  The results for 1993 include a non-taxable gain of $15.1 million (before
     minority interest), relating to the issuance of shares by Rust, as well as
     a special asset revaluation and restructuring charge of $524.8 million
     (before tax and minority interest) recorded by CWM related primarily to a
     revaluation of its thermal treatment business, and a provision of
     approximately $14 million to adjust deferred income taxes resulting from
     the 1993 tax law change.

(4)  The results for 1995 include a special charge of $140.6 million (before
     tax) recorded by CWM, primarily to write off its investment in facilities
     and technologies that it abandoned because they do not meet customer
     service or performance objectives, and a special charge of $194.6 million
     (before tax and minority interest) recorded by WM International relating to
     actions it had decided to take to sell or otherwise dispose of non-core
     businesses and investments, as well as core businesses and investments in
     low potential markets, abandon certain hazardous waste treatment and
     processing technologies, and streamline its country management
     organization.

(5)  In 1995, the Rust Board of Directors approved a plan to sell or otherwise
     discontinue Rust's process engineering, construction, specialty contracting
     and similar lines of business. During 1996, the sale of the industrial
     process engineering and construction business, based in Birmingham,
     Alabama, was completed. In 1996, WTI sold its water process systems and
     equipment manufacturing businesses, and Rust sold its industrial
     scaffolding business. WTI entered into an agreement to sell its water and
     wastewater facility operations and privatization business and Rust began
     implementing plans to exit its remaining domestic and international
     engineering and consulting business. These businesses were classified as
     discontinued operations in the financial statements. The Rust disposition
     was not completed within one year, and accordingly in 1997 this business
     has been reclassified back into continuing operations, as operations held
     for sale, in accordance with generally accepted accounting principles. The
     unused portion ($87.0 million) of the previously recorded provision for
     loss on disposal was reversed in discontinued operations, and an impairment
     loss provision of $122.2 million was recognized in continuing operations.

(6)  The results for 1996 include special charges of $47.1 million (before tax
     and minority interest) related to WM International's sale of its investment
     in Wessex and a charge of $169.5 million (before tax and minority interest)
     to revalue its investments in France, Austria and Spain in contemplation of
     exiting these markets and to write off an investment in a hazardous waste
     disposal facility. Also in 1996, WMNA and CWM recorded special charges of
     $154.1 million (before tax) for reengineering their finance and
     administration functions and increasing reserves for certain litigation.

(7)  In 1997, the Company recorded a special charge of $41.6 million (pretax)
     for severance related to WMNA and WM International recorded a charge of
     $104.4 million (before tax and minority interest) to reflect costs of
     demobilization following the loss of the contract renewal for Buenos Aires,
     Argentina, divestiture or closure of underperforming businesses, and the
     writeoff of projects it decided to no longer pursue. Also in 1997, the
     Company recorded an asset impairment loss and restated prior year financial
     statements to retroactively recognize impairment losses in earlier years.
     See Note 16 to Consolidated Financial Statements.

(8)  Earnings are inadequate to cover fixed charges in 1997. Coverage deficiency
     represents the amount that earnings would have to increase ($1,026.1
     million) to cover fixed charges and bring the ratio of earnings to fixed
     charges to one-to-one.
