ITEM 1.   BUSINESS

INTRODUCTION

     Stericycle, Inc. (the "Company") is a multi-regional integrated company 
employing its proprietary technology to provide environmentally-responsible 
management of regulated medical waste for the health care industry. Because 
of the Company's health care orientation, proprietary technology and breadth 
of service, the Company believes that it is in a unique position to meet the 
fundamental need of the health care industry to manage regulated medical 
waste in a safe and cost-effective manner and to capitalize on the current 
consolidation trend in the regulated medical waste management industry. The 
Company believes that its exclusive focus on regulated medical waste and the 
experience of its management in the health care industry distinguish the 
Company from its chief competitors.

     The Company believes that its regulated medical waste management system, 
including its proprietary ELECTRO-THERMAL-DEACTIVATION  ("ETD") treatment 
process, is the only commercially-proven system that provides all of the 
following benefits: (i) it kills human pathogens in regulated medical waste 
without generating liquid effluents or regulated air emissions; (ii) it 
affords certain operating cost advantages over the principal competing 
treatment methods; (iii) it reduces the volume of regulated medical waste by 
up to 85%; (iv) it renders regulated medical waste unrecognizable; (v) it 
permits the recovery and recycling of usable plastics from regulated medical 
waste; and (vi) it enables the remaining regulated medical waste to be safely 
landfilled or used as an alternative fuel in energy production. The Company's 
full-service program is designed to help to protect its customers and their 
employees against potential liabilities and injuries in connection with the 
handling, transportation and disposal of regulated medical waste.

     The Company's integrated services include regulated medical waste 
collection, transportation, treatment, disposal, reduction, reuse and 
recycling services, together with related training and education programs, 
consulting services and product sales, in seven geographic service areas: (i) 
California and Arizona; (ii) Oregon, Washington, Idaho and British Columbia; 
(iii) Illinois, Indiana, Iowa, Minnesota and Wisconsin; (iv) Ohio, Michigan, 
Kentucky and  Tennessee; (v) Texas; (vi) Connecticut, Massachusetts, Maine, 
New Hampshire, Rhode Island and Vermont; and (vii) Delaware, Maryland, New 
Jersey, New York, North Carolina, Pennsylvania, South Carolina, Virginia, 
West Virginia and the District of Columbia. As of December 31, 1997, the 
Company served approximately 40,000 customers, consisting of two principal 
types of generators of regulated medical waste. Approximately 50-60% of the 
Company's 1997 revenues were derived from hospitals, blood banks and 
pharmaceutical manufacturers ("Core" generators), and the balance of its 
revenues were derived from long-term and subacute care facilities, outpatient 
clinics, medical and dental offices, industrial clinics, dialysis centers, 
laboratories, biotechnology and biomedical companies, veterinary offices, 
municipal health departments, ambulance, fire and police departments, 
correctional facilities, schools, park districts and funeral homes 
("Alternate Care" generators).

     Regulated medical waste is generally defined as any waste that can cause 
an infectious disease or that can reasonably be suspected of harboring human 
pathogenic organisms. Regulated medical waste includes single-use disposable 
items such as needles, syringes, gloves and laboratory, surgical, emergency 
room and other supplies which have been in contact with blood or bodily 
fluids; cultures and stocks of infectious agents; and blood and blood 
products. An independent study published in 1995 estimated that the size of 
the regulated medical waste management market in the United States in 1997 
was  in excess of $1 billion.

     Based upon certain public information and the Company's estimates of its 
competitors' revenues, the Company believes that it is the second-largest 
provider of regulated medical waste management services in the United States.

                                       1

TRENDS IN THE HEALTH CARE AND MEDICAL WASTE INDUSTRIES

     The Company believes that the demand for its services will grow as a 
consequence of certain trends in the health care and regulated medical waste 
industries.

     INCREASED AWARENESS OF REGULATED MEDICAL WASTE.  The handling and 
disposal of the large quantities of regulated medical waste generated by the 
health care industry has attracted increased public awareness and regulatory 
attention. The proper management of potentially infectious medical waste 
gained national attention in 1988 when disposable syringes and other medical 
waste washed ashore on New Jersey and New York coastlines.

     These events raised concerns about the potential transmission of 
hepatitis B, HIV and other infectious diseases. The Medical Waste Tracking 
Act of 1988 ("MWTA") was enacted in response to this problem and established 
a multi-year demonstration program for the proper tracking and treatment of 
medical waste. Many states have enacted legislation modeled on MWTA's 
requirements.

     In addition, the Occupational Health and Safety Administration ("OSHA") 
has issued regulations concerning employee exposure to bloodborne pathogens 
and other potentially infectious material that require, among other things, 
special procedures for the handling and disposal of regulated medical waste 
and annual training of all personnel who are potentially exposed to blood and 
other bodily fluids. The Company believes that the scope of these regulations 
will help to expand the market for the Company's services beyond traditional 
providers of health care.

     As a consequence of these legislative and regulatory initiatives, the 
Company believes that health care providers and other generators of regulated 
medical waste have become increasingly concerned about the handling, 
treatment and disposal of regulated medical waste. These concerns are 
reflected by their desire:  (i) to reduce on-site handling of regulated 
medical waste in order to minimize employee contact; (ii) to assure safe 
transportation of regulated medical waste to treatment sites; (iii) to assure 
destruction of potentially infectious human pathogens; (iv) to render the 
treated regulated medical waste non-recognizable in order to reduce liability 
and to increase disposal options; (v) to minimize the impact of the treatment 
process on the environment and the volume of solid waste deposited in 
landfills; and (vi) to participate in recycling programs where possible and 
when cost-effective.

     GROWING IMPORTANCE OF ALTERNATE CARE GENERATORS.  The Company believes 
that in response to managed care and other health care cost-containment 
pressures, patient care is increasingly shifting from higher-cost acute-care 
settings to less expensive off-site treatment alternatives. According to a 
report published by the U.S. Health Care Financing Authority, total 
alternate-site health care expenditures in the United States increased from 
approximately $5 billion in 1985 to approximately $22 billion in 1994. The 
Company believes that alternate-site health care expenditures will continue 
to grow in response to governmental and private cost-containment initiatives. 
Many common diseases and conditions, including pulmonary diseases, 
neurological conditions, infectious diseases, digestive disorders, AIDS and 
various forms of cancer are now being treated in alternate-site settings.

     Alternate Care generators have become an increasingly important source 
of revenues in the regulated medical waste industry. An independent report in 
1990 estimated that approximately 23% (by weight) of regulated medical waste 
was produced by Alternate Care generators. Based on the Company's experience, 
the Company believes both that this percentage has increased significantly 
and that Alternate Care generators account for a greater percentage of 
regulated medical waste treatment revenues than the percentage of regulated 
medical waste volume that they generate. Individual Alternate Care generators 
typically do not produce a sufficient volume of regulated medical waste to 
justify substantial capital expenditures on their own waste treatment 
facilities or the expense of hiring regulatory compliance personnel. 
Accordingly, the Company believes that Alternate Care generators are 
extremely service-sensitive, relying on their regulated medical waste 
management provider for timely waste removal, creative solutions for safer 
regulated medical waste handling, establishment of regulated medical waste 
management protocols,

                                       2

<PAGE>


education on regulated medical waste reduction techniques and assistance with 
compliance and recordkeeping. The Company believes that growth in the number 
of Alternate Care generators will generate growth in the overall regulated 
medical waste market and may provide growth opportunities for the Company.

     HEALTH CARE COST CONTAINMENT INITIATIVES.  The health care industry is 
under increasing pressure to reduce costs and improve efficiency. The Company 
believes that its regulated medical waste management services facilitate cost 
containment by health care providers by reducing their regulated medical 
waste tracking, handling and compliance costs, reducing their potential 
liability related to employee exposure to bloodborne pathogens and other 
potentially infectious material, and significantly reducing the amount of 
capital invested in on-site treatment of regulated medical waste.

     SHIFT FROM ON-SITE INCINERATION TO OFF-SITE TREATMENT.  The Company 
believes that during the past five years, government clean air regulations 
have increased both the capital costs required to bring many existing 
incinerators into compliance with such regulations and the operating costs of 
continued compliance. As a result, many hospitals have shut down their 
incinerators. This trend is expected to accelerate in response to regulations 
which  the U.S. Environmental Protection Agency ("EPA")  adopted  in 
September 1997 limiting the discharge into the atmosphere of nine pollutants 
released by hospital waste incineration.  The EPA estimates that of the 
approximately 1,100 small, 690 medium and 460 large hospital medical waste 
incinerators currently in operation, approximately 93-100% of the small 
incinerators, 60-95% of the medium incinerators and as many as 35% of the 
large incinerators will be closed as hospitals seek alternative, less 
expensive methods of regulated medical waste disposal rather than incur the 
cost of installing the necessary air pollution control systems to comply with 
EPA regulations. The Company agrees with the thrust of the EPA's estimates 
and expects to benefit from this anticipated movement by hospitals to 
alternative methods of regulated medical waste disposal.

     INDUSTRY CONSOLIDATION.  Although the regulated medical waste management 
industry remains fragmented, the number of competitors is rapidly decreasing 
as a result of industry consolidation. National attention on regulated 
medical waste in the late 1980s led to rapid growth in the industry and a 
highly-fragmented competitive structure. Entrants into the industry included 
several large municipal waste companies and many independent haulers and 
incinerator operators. Since 1990, however, government clean air regulations 
and public concern about the environment have increased the costs and public 
opposition to both on- and off-site regulated medical waste incineration. As 
a result, the Company believes that independent haulers and incinerator 
operators have encountered increasing difficulty competing with integrated 
companies like the Company, which typically have their own low-cost treatment 
plants located within the geographic areas that they serve. The Company 
believes that many of these independent haulers are withdrawing from the 
regulated medical waste industry. As a result of industry consolidation, the 
Company believes that it has increasing opportunities to acquire medical 
waste management businesses.

GROWTH STRATEGY

     The Company is currently the second-largest provider of regulated 
medical waste management services in the United States. The Company's goals 
are to accelerate its revenue growth through penetration of existing 
geographic service areas and expansion into new areas and to increase profits 
through additional revenues and the more efficient use of its existing 
infrastructure.

     INCREASED PENETRATION OF EXISTING SERVICE AREAS.  All of the Company's 
treatment facilities are currently operating below capacity. Due to the high 
fixed costs associated with the collection and treatment of regulated medical 
waste, the Company's operating margins increase with incremental volume 
gains. Accordingly, the Company is currently implementing a number of 
programs to increase customer density, particularly among Alternate Care 
generators, andto improve penetration of its existing geographic service 
areas in order to maximize operating efficiencies. The Company focuses its 
telemarketing and direct sales efforts at securing agreements with new 
customers among both Core and Alternate Care generators, with a predominant 
focus on Alternate Care generators. The Company intends to acquire competitors

                                       3

and enter into marketing alliances with various hospitals, health maintenance 
organizations, medical suppliers and others.

     GEOGRAPHIC EXPANSION.  In order to expand its geographic coverage, the 
Company plans, among other things, to develop additional transfer stations, 
acquire independent haulers and integrated competitors, expand its 
telemarketing and direct sales efforts and where appropriate construct new 
treatment facilities. The Company estimates that its existing transportation 
and treatment system enables it to serve effectively an area encompassing 
approximately 60% of the U.S. population. The Company believes that expanding 
its "hub and spoke" transportation strategy would allow it to maximize the 
utilization of existing treatment facilities by channeling waste through 
existing and additional transfer stations. The Company estimates that doing 
so would enable it to serve effectively an area encompassing approximately  
70% of the U.S. population. In order to reach new geographic service areas, 
the Company is exploring acquiring independent haulers and integrated 
competitors. The Company believes that expanding telemarketing and direct 
sales efforts will increase customer density in existing and new geographic 
service areas. A combination of these factors may lead to the construction of 
additional treatment and other facilities.

     OTHER GROWTH OPPORTUNITIES.  The Company believes that it has the 
opportunity to expand its business by increasing the range of products and 
services that it offers to its existing customers and by adding new customer 
categories. The Company, for example, may expand its collection, treatment, 
disposal and recycling of regulated medical waste generated by health care 
providers to include wastes that are currently handled by the Company only on 
a limited basis, such as photographic chemicals, lead foils and amalgam used 
in dental and radiology laboratories. In addition, the Company may decide to 
offer single-use disposable medical supplies to its customers. The Company is 
exploring marketing alliances with organizations that focus on Alternate Care 
generators.

      The Company is also investigating expansion into international markets. 
In 1996, the Company entered into an agreement with a Brazilian company to 
assist in exploring opportunities for the commercialization of the Company's 
medical waste management technology in certain territories in South America. 
In February, 1998, the Company announced the formation of a Mexican joint 
venture company, Medam S.A. de C.V. ("Medam"), to utilize the Company's ETD 
technology to treat medical and infectious waste in the Mexico City market. 
Medam, which was formed with an established Mexican  company and an American 
firm of international consulting engineers, has obtained the appropriate 
permits to construct a treatment facility with a 100-ton per day capacity. 
This facility is the largest permitted for construction to date in Mexico and 
is expected to be completed in 1998.

ACQUISITION PROGRAM

     The acquisition of other regulated medical waste management businesses, 
including both independent haulers and integrated competitors, is a key 
element of the Company's strategy to increase the number of customers in its 
current markets and to expand its operations geographically. Many of these 
potential acquisition candidates participate in both the solid waste industry 
as well as the regulated medical waste industry. The Company believes that 
its exclusive focus on the regulated medical waste industry makes it an 
attractive buyer for the medical waste operations of these companies. The 
Company believes that its expansion strategy also makes it an attractive 
buyer to haulers whose owners may wish to remain active in their businesses, 
both as managers and as equity holders, while participating in the growth 
potential inherent in an industry consolidation. In addition, the Company 
believes that its customer-service focus makes it an attractive buyer to 
owners who place significant importance on the assurance that their customers 
will receive quality service following the sale of their businesses.

     Prior to 1997, the Company completed nine acquisitions: Therm-Tec 
Destruction Service of Oregon, Inc. in 1993; Recovery Corporation of Illinois 
and Safeway Disposal Systems, Inc. in 1994;, Safetech Health Care, Inc. in 
1995; and Bio-Med of Oregon, Inc., WMI Medical Services of New England, Inc., 
Doctors Environmental Control, Inc., Sharps Incinerator of Fort, Inc., and a 
majority of the regulated medical waste management business of Waste 
Management, Inc. ("WMI"), all in  1996.

                                       4

<PAGE>D

     During 1997, the Company completed eight acquisitions. In May, the 
Company announced the acquisition of Environmental Control Co., Inc., one of 
the leading medical waste companies in the New York City market. In June, the 
Company purchased the customer list and certain other assets of WMI's 
regulated medical waste business  in Wisconsin, and in July, the Company 
announced the purchase of the customer lists and certain other assets of 
Regional Carting, Inc. and Rumpke Container Service, Inc. in New Jersey and 
Ohio, respectively. In August 1997, the Company completed the purchase of the 
customer list and certain other assets of Envirotech Enterprises, Inc. in 
Tucson, Arizona, and in November, the Company completed the acquisition of 
substantially all of the assets of Cal-Va, Inc., which operated in northern 
Virginia and Washington, D.C., and selected Alternate Care contracts of 
Phoenix Services, Inc., which operated in the Baltimore, Maryland 
metropolitan area. In December, the Company bought certain of the assets of 
the regulated medical waste business in Arizona of Browning-Ferris 
Industries, Inc. ("BFI") and sold BFI certain of the assets of the Company's 
regulated medical waste business in Colorado and Utah. The purchase price for 
these acquisitions was paid by a combination of cash, promissory notes, 
shares of the Company's Common Stock and assumption of liabilities.

     The Company's senior management is actively involved in identifying 
acquisition candidates and consummating acquisitions. In determining whether 
to proceed with a business acquisition, the Company evaluates a number of 
factors including: (i) the composition and size of the seller's customer 
base; (ii) the efficiencies that may be obtained when the acquisition is 
integrated with one or more of the Company's existing operations; (iii) the 
potential for enhancing or expanding the Company's geographic service area 
and allowing the Company to make other acquisitions in the same service area; 
(iv) the seller's historical and projected financial results; (v) the 
purchase price negotiated with the seller and the Company's expected internal 
rate of return; (vi) the experience, reputation and personality of the 
seller's management; (vii) the seller's customer service reputation and 
relationships with the communities that it serves; (viii) if the acquisition 
involves the assumption of liabilities, the extent and nature of the seller's 
liabilities, including environmental liabilities; (viii) whether the 
acquisition gives the Company any strategic advantages over its competition; 
and (ix) the effect of the proposed acquisition on the Company's earnings per 
share.

     The Company has established a procedure for efficiently integrating 
newly-acquired companies into its business while minimizing disruption of the 
continuing operations of both the Company and the acquired business. Once a 
medical waste management business is acquired, the Company  makes plans to 
implement programs designed to improve customer service, sales, marketing, 
routing, equipment utilization, employee productivity, operating efficiencies 
and overall profitability.

     The Company anticipates that its future acquisitions of other regulated 
medical waste management businesses will be made by the payment of cash, the 
issuance of debt or equity securities or a combination of these methods. The 
Company believes that its acquisition strategy will be enhanced by the fact 
that the Company's Common Stock is publicly-traded. Historically, the 
Company's acquisition strategy has been to acquire selected assets of 
regulated medical waste management businesses, consisting principally of 
customer lists, customer contracts, vehicles and related supplies and 
equipment. Some of the Company's acquisitions have also involved the 
Company's assumption of certain liabilities of the seller.

TREATMENT TECHNOLOGIES

     The three most common off-site commercial technologies for treating 
regulated medical waste are incineration, autoclaving and the Company's 
proprietary ETD treatment process. Alternative technologies and methods, 
which have not gained wide commercial acceptance, include chemical treatment, 
microwaving and certain specialized or experimental technologies, including 
the development and marketing of reusable or degradable medical products 
designed to reduce the generation of regulated medical waste. The Company 
believes that the ETD treatment process has certain advantages over 
incineration and autoclaving.

                                       5

<PAGE>

PRINCIPAL TREATMENT TECHNOLOGIES

     INCINERATION.  The Company estimates that incineration accounts for 
approximately 65-70% of permitted off-site capacity to treat regulated 
medical waste. Incineration burns regulated medical waste at elevated 
temperatures and reduces it to ash. Like ETD, incineration significantly 
reduces the volume of waste, and it is the recommended treatment and disposal 
option for certain types of regulated medical waste such as anatomical waste 
or residues from chemotherapy procedures. Incineration has come under 
increasing criticism from the public and from state and local regulators, 
however, because of the airborne emissions that it generates. Emissions from 
incinerators can contain pollutants such as dioxins, furans, carbon monoxide, 
mercury, cadmium, lead and other toxins which are subject to federal, state 
and, in some cases, local regulation. The fly-ash by-product of incineration 
may also constitute a hazardous substance. As a result, there is a 
significant cost to construct new incineration facilities, or to improve 
existing facilities, to insure that their operation is in compliance with 
regulatory standards.

     AUTOCLAVING.  The Company estimates that autoclaving accounts for 
approximately 20-25% of permitted off-site capacity to treat regulated 
medical waste. Autoclaving treats regulated medical waste with steam at high 
temperature and pressure to kill pathogens. The technology is most effective 
if all surfaces are uniformly exposed to the steam, but uniform exposure may 
not always occur, potentially leaving some pathogens untreated. In addition, 
autoclaving alone does not change the appearance of waste, and recognizable 
regulated medical waste may not be accepted by landfill operators. To 
compensate for this disadvantage, autoclaving may be combined with a 
shredding or grinding process to render the regulated medical waste 
non-recognizable. The high temperatures generated in the autoclaving process 
occasionally change the physical properties of plastic waste, prohibiting its 
recycling.

     ETD TREATMENT PROCESS.  The Company estimates that its patented ETD 
treatment process accounts for approximately 8% of permitted off-site 
capacity to treat regulated medical waste. ETD also includes a proprietary 
system for grinding regulated medical waste. ETD uses an oscillating energy 
field of low-frequency radio waves to heat regulated medical waste to 
temperatures that destroy pathogens such as viruses, vegetative bacteria, 
fungi and yeast without melting the plastic content of the waste. ETD is most 
effective on materials with low electrical conductivity that contain polar 
molecules, including all human pathogens. Polar molecules are molecules that 
have an asymmetric electronic structure and tend to align themselves with an 
imposed electric field. When the polarity of the applied field changes 
rapidly, the molecules try to keep pace with the alternating field direction, 
thus vibrating and in the process dissipating energy as heat. The Company 
believes that the electric field created by ETD produces high molecular 
agitation and thus rapidly creates high temperatures. All of the molecules 
exposed to the field are agitated simultaneously, and accordingly, heat is 
produced evenly throughout the waste instead of being imposed from the 
surface as in conventional heating. This phenomenon, called volumetric 
heating, transfers energy directly to the waste, resulting in uniform heating 
throughout the entire waste material and eliminating the inherent 
inefficiency of transferring heat first from an external source to the 
surface of the waste and then from the surface to the interior of the waste 
material. ETD employs low-frequency radio waves because they can penetrate 
deeper than high-frequency waves, such as microwaves, which can penetrate 
regulated medical waste of a typical density only to a depth of approximately 
five inches. ETD uses specific frequencies that match the physical properties 
of regulated medical waste generally enabling the ETD treatment process to 
kill pathogens while maintaining the temperature of the non-pathogenic waste 
at temperatures as low as 90DEG.  C. Although ETD is effective in destroying 
pathogens present in anatomical waste, the Company does not currently treat 
anatomical waste through the ETD process.

     ADVANTAGES OF THE COMPANY'S ETD TREATMENT PROCESS

     The Company believes that its proprietary ETD treatment process provides 
certain advantages over incineration and certain advantages over autoclaving.

     PERMITTING.  It is difficult and time-consuming to obtain the permits
necessary to construct and operate any regulated medical waste treatment
facility, regardless of the treatment technology to be

                                       6

<PAGE>


employed at the proposed facility. Local residents, citizen groups and 
elected officials frequently object to the construction and operation of 
proposed regulated medical waste treatment facilities solely because 
regulated medical waste will be transported to and stored and handled at the 
facility. The Company believes, however, that the fact that the ETD treatment 
process does not generate liquid effluents or regulated air emissions may 
enable the Company to locate treatment facilities near dense population 
centers, where greater numbers of potential customers are found, with less 
difficulty than would be encountered by a competitor attempting to locate an 
incinerator in the same area.

     COST.  The Company believes that it is less expensive to construct and 
operate an ETD treatment facility than to construct and operate either a 
like-capacity incinerator or a like-capacity autoclave with shredding 
capability, which may enable the Company to price its treatment services 
competitively. The Company believes that the comparative advantage that it 
possesses in its ability to locate treatment facilities near dense population 
centers may also provide transportation and operating efficiencies.

     VOLUME REDUCTION AND UNRECOGNIZABILITY.  The Company's regulated medical 
waste management program reduces the overall volume of regulated medical 
waste in several ways. The Company's patented reusable container, used under 
the trademark STERI-TUB-Registered Trademark-, replaces the use of corrugated 
containers for many Core and Alternate Care generators of large amounts of 
regulated medical waste, thus reducing waste volume by as much as 10-15%. 
Once medical waste has undergone the ETD treatment process, the original 
cubic volume of the waste is reduced by approximately 85%. This reduction in 
the volume of regulated medical waste is comparable to the volume reduction 
obtained by incineration. Autoclaving alone does not reduce the volume of 
regulated medical waste or render it unrecognizable. To reduce waste volume 
and to overcome the unwillingness of many landfill operators to accept 
recognizable treated regulated medical waste, autoclaving must be combined 
with a shredding or grinding operation, adding to its cost. A proprietary 
grinding feature is a component of the ETD treatment process. The Company 
believes that the ability of its ETD treatment process both to reduce the 
volume of regulated medical waste and to render it unrecognizable gives the 
Company's process an advantage over autoclave operations that do not include 
shredding or grinding.

     REUSE AND RECYCLING.  The Company believes that its reuse and recycling 
capabilities provide a marketing advantage with customers who prefer to use a 
regulated medical waste management provider with a commitment to resource 
conservation. The Company's customers can participate in a voluntary 
recycling program by source-segregating their regulated medical waste. The 
source-segregated regulated medical waste is treated by the ETD treatment 
process and, in certain geographic service areas, can then be processed 
through the Company's proprietary systems for the automatic recovery of 
polypropylene plastics. The recovered polypropylene plastics are used by a 
third party to manufacture a line of "sharps" containers which are used by 
health care providers to dispose of sharp objects such as needles and blades. 
In addition, in three of the Company's geographic service areas, the 
Company's treated regulated medical waste is transported to resource recovery 
facilities owned by third parties where it is used as refuse-derived fuel in 
"waste-to-energy" plants to produce electricity. The Company has worked to 
develop a process in conjunction with a cement manufacturer to utilize 
treated regulated medical waste as a fossil fuel substitute in cement kilns. 
As a result of grinding, reuse and recycling, only approximately 6% of the 
original cubic volume of the regulated medical waste treated by the Company 
during 1997 was disposed of in landfills.

     COMPANY'S USE OF OTHER TECHNOLOGIES.  Under the terms of certain 
acquisitions by the Company, the Company is required to use the seller's 
incineration or autoclave facilities for a specified period. Accordingly, not 
all of the regulated medical waste that the Company collects is treated using 
the Company's ETD technology.

MARKETING AND SALES

     MARKETING STRATEGY.  The Company's marketing strategy is to provide 
customers with a complete cost management and compliance program for their 
regulated medical waste. In addition to its regulated

                                       7

<PAGE>


medical waste collection, transportation, treatment and disposal services, 
the Company also offers a variety of training and education programs and 
consulting services to its customers. The Company's senior management and 
many of its other employees are experienced health care professionals able to 
convey the importance of these issues in the healthcare marketplace.

     The Company's marketing strategy recognizes that its potential customers 
are generally health care providers, who approach the problem of regulated 
medical waste management from a different perspective than typical generators 
of solid or municipal waste. Health care personnel have become increasingly 
sensitive to the risk of contracting diseases such as AIDS and hepatitis 
through accidental contact with infected patient blood. In addition, patients 
are increasingly demanding that practitioners demonstrate continual vigilance 
against such risks. Regulations which have been adopted by OSHA require 
annual training of all personnel who potentially can come into contact with 
bloodborne pathogens and other potentially infectious materials. These 
regulations also require documentation of handling procedures and detailed 
clean-up plans. As a result, there is a heightened awareness by health care 
providers of the need to implement safeguards against such risks.

     The Company has developed programs to help train employees of customers 
on the proper methods of handling, segregating and containing regulated 
medical waste in order to reduce their potential exposure. The Company can 
also advise health care providers on the proper methods of recording and 
documenting their regulated medical waste management in order to comply with 
federal, state and local regulations. In addition, the Company offers 
consulting and review services to such providers regarding their internal 
collection and control systems and assists them in developing systems to 
provide for the efficient management of their regulated medical waste from 
the point of generation through treatment and disposal. The Company also 
offers consulting services to its health care customers to assist them in 
reducing the amount of regulated medical waste at the point of generation.

     The Company's marketing and sales efforts are an integral part of its 
strategy of pursuing opportunities for targeted growth. The Company attempts 
to focus its marketing and sales efforts on potential customers that will 
yield the greatest transportation and operating advantages.

     CORE GENERATORS.  The Company's marketing and sales efforts to Core 
generators are conducted by account executives whose responsibilities include 
identifying and attracting new customers and serving existing customers. In 
addition, the Company employs customer service representatives to assist its 
account executives. The Company's marketing and sales personnel are trained 
to understand the issues confronting Core generators of regulated medical 
waste. In addition to securing customer contracts, the Company's marketing 
and sales personnel provide consulting services to its health care customers 
to assist them in reducing the amount of regulated medical waste that they 
generate, training their employees on safety issues and implementing programs 
to audit, classify and segregate regulated medical waste in a proper manner.

     The Company has secured several large and prestigious hospitals and 
health care institutions as customers, including Sharp HealthCare in 
California; the Kaiser Permanente Medical Care Program in California, 
Washington and Oregon; Northwestern Memorial Hospital in Illinois; and VHA 
Healthfront in New England. The Company believes that its relationship with 
these and other similarly well-known institutions will enhance its ability to 
market its services to other Core generators and surrounding Alternate Care 
generators.

     The Company's marketing and sales efforts directed to Core generators 
are supplemented by several strategic marketing alliances. In October 1993, 
the Company entered into an alliance agreement with Baxter Healthcare 
Corporation ("Baxter"). A key component of this agreement is the expansion of 
Baxter's procedure-based delivery system ("PBDS") to include regulated 
medical waste disposal by the Company. Under PBDS, Baxter hospital supplies 
are custom-packed in containers provided by the Company based on the 
requirements of a specific hospital and, in many cases, the requirements of a 
specific medical provider. Baxter's agreement to include regulated medical 
waste disposal as part of PBDS was intended to assist its

                                       8

<PAGE>

customers in consolidating the specific costs of a patient procedure. The 
alliance agreement enables the Company potentially to benefit from Baxter's 
marketing efforts and promotion of PBDS to link the sale of the Company's 
regulated medical waste disposal services to Baxter's sale of certain of its 
disposable hospital supplies. In connection with the alliance agreement, 
Baxter paid $8,000,000 to purchase shares of the Company's preferred stock, 
of which the Company was required to spend $1,000,000 for research and 
development related to enhancements of the Company's technology to increase 
recycling of Baxter's products. In September 1996, Baxter's parent 
corporation, Baxter International Inc., spun off its domestic hospital supply 
and health care cost management businesses, which had sales of approximately 
$4.58 billion in 1995, to a new company, Allegiance Corporation 
("Allegiance"),  and in connection with the spin-off Baxter transferred its 
interest in the alliance agreement to Allegiance. In addition to this  
alliance, the Company has entered into strategic marketing alliances with 
several hospital associations pursuant to which the Company may receive 
endorsements or marketing assistance.

     ALTERNATE CARE GENERATORS.  The Company's marketing and sales efforts 
for Alternate Care generators are conducted by telemarketing representatives 
who use the Company's proprietary database to identify and qualify potential 
customers and set appointments for the Company's trained field sales 
representatives. These field sales representatives provide follow-up customer 
service and ancillary product sales. The Company has refined its 
telemarketing system and believes it to be a cost-effective means to reach 
the numerous Alternate Care generators of small quantities of regulated 
medical waste. The Company's sales efforts are supplemented by several 
strategic marketing agreements with, for example, the Massachusetts Dental 
Society and the Sisters of Providence Health System in Washington and Oregon, 
under which the Company may receive endorsements or marketing assistance.

     SERVICE AGREEMENTS.  The Company negotiates individual service 
agreements with each Core and Alternate Care generator customer. Although the 
Company has a standard form of agreement, terms vary depending upon the 
customer's service requirements and volume of regulated medical waste 
generated. Service agreements typically include provisions relating to types 
of containers, frequency of collection, pricing, treatment, and documentation 
for tracking purposes. Each agreement also specifies the customer's 
obligation to pack its regulated medical waste in approved containers. 
Service agreements are generally for a period of one to five years and 
include renewal options, although customers may terminate on written notice 
and typically upon payment of a penalty. Many payment options are available 
including flat monthly or quarterly charges. The Company may set its prices 
on the basis of the number of containers that it collects, the weight of the 
regulated medical waste that it collects and treats, the number of collection 
stops that it makes on the customer's route, the number of collection stops 
that it makes for a particular multi-site customer, and other factors.

     The Company has a diverse customer base, with no single customer 
accounting for more than 3% of the Company's 1997 revenues. The Company does 
not believe that the loss of any single customer would have a material 
adverse effect on its business, financial condition or results of operations.

LOGISTICS

     An important element of the Company's business strategy is to maximize 
the efficiency with which it collects and transports a large volume of 
regulated medical waste and directs the deployment of many collection 
vehicles. This aspect of the Company's operations--referred to as 
logistics--represents the Company's single largest operating cost. 
Accordingly, the Company considers logistics to be a critical component of 
its operating plan. The Company's integrated approach to regulated medical 
waste management is designed to provide it with numerous logistic advantages 
in the process of managing regulated medical waste.

     PRE-COLLECTION.  Before regulated medical waste is collected, the 
Company's integrated waste management approach can "build in" efficiencies 
that will yield logistic advantages. For example, the Company's consulting 
services can assist its customers in minimizing their regulated medical waste 
volume at the point of generation. In addition, the Company provides 
customers with the documentation necessary

                                       9

<PAGE>

for regulatory compliance which, if properly completed, will minimize
interruptions in the regulated medical waste treatment cycle for verification of
regulatory compliance.

     CONTAINERS.  A key element of the Company's pre-collection measures is 
the use of specially designed containers by most of the Company's Core and 
Alternate Care generators of large volumes of regulated medical waste. The 
Company has developed and patented a reusable leak- and puncture-resistant 
container, called a STERI-TUB, made from recycled plastic. The STERI-TUB 
enables regulated medical waste generators to reduce costs by reducing the 
number of times that regulated medical waste is handled, eliminating the cost 
(and weight) of corrugated boxes and potentially reducing workers' 
compensation liability resulting from human contact with regulated medical 
waste. The Company has introduced two smaller sizes of STERI-TUBS that are 
popular in certain areas of hospitals, such as the laboratory, and with many 
Alternate Care generators. The Company has also developed a step-on lid 
opener and a sliding lid that fit the various sizes of STERI-TUBS and make 
STERI-TUBS even safer and more convenient to use. STERI-TUBS are designed to 
maximize the loads that will fit within the cargo compartments of standard 
trucks and trailers. The Company believes these features to be an improvement 
over its competitors' reusable "point-of-generation" containers. The 
Company's customers are responsible for packing their regulated medical waste 
in a STERI-TUB or approved corrugated container and placing the loaded 
containers at a designated collection area on their premises. If a customer 
generates a large volume of waste, the Company will place a large temporary 
storage container or trailer on the customer's premises. In order to maximize 
regulatory compliance and minimize potential liability, the Company will not 
accept medical waste unless it is properly packaged by customers in 
Company-supplied or Company-approved containers.

     COLLECTION AND TRANSPORTATION.  Efficiency of collection and 
transportation is a critical element of the Company's logistics. The Company 
seeks to maximize route density and the number of stops on each route. The 
Company also employs a tracking system for its collection vehicles which is 
designed to maximize logistic efficiency. The Company deploys dedicated 
collection vehicles of different capacities depending upon the amount of 
regulated medical waste to be collected at a particular stop or on a 
particular route. The Company collects containers of regulated medical waste 
from its customers at intervals depending upon customer requirements, terms 
of the service agreement and the volume of regulated medical waste produced. 
All containers are inspected at the customer's site prior to pickup. The 
waste is then transported directly to one of the Company's treatment 
facilities or to one of the Company's transfer stations where it is 
aggregated with other regulated medical waste and then transported to a 
treatment facility. In certain circumstances, the Company transports waste to 
other specially-licensed regulated medical waste treatment facilities. The 
Company transports small quantities of hazardous substances, such as 
photographic fixer, lead foils and amalgam, from certain of its customers to 
a metals recycling operation.

     TRANSFER STATIONS.  The use of transfer stations is another important 
component of the Company's logistics. The Company utilizes transfer stations 
in a "hub and spoke" configuration which allows the Company to expand its 
geographic service area and increase the volume of regulated medical waste 
that can be treated at a particular facility. Smaller loads of waste 
containers are stored at the transfer stations until they can be consolidated 
into full truckloads and transported to a treatment facility.

     INSPECTION, TREATMENT AND DISPOSAL.  Upon arrival at a treatment facility,
each container of regulated medical waste is scanned to verify that it does not
contain any unacceptable materials such as hazardous substances or radioactive
material. Any container which is discovered to contain hazardous substances or
radioactive material is returned to the customer. In some cases the Company's
operating permits require that unacceptable waste be reported to the appropriate
regulatory authorities. After inspection, the regulated medical waste is loaded
into the processing system and ground, compacted and treated using the Company's
ETD treatment process. Upon completion of this process, the treated medical
waste is transported for resource recovery, recycling or disposal in a
nonhazardous waste landfill. After the STERI-TUBS have been emptied, they are
washed, sanitized and returned to customers for re-use.

     As previously noted (see "Treatment Technologies--Advantages of the 
Company's ETD  Treatment Process--Company's Use of Other Technologies"), 
under the terms of certain acquisitions by the Company,

                                       10

<PAGE>


the Company is required to use the seller's incineration or autoclave 
facilities for a specified period. Accordingly, not all of the regulated 
medical waste that the Company collects is treated using the Company's ETD 
technology.

     DOCUMENTATION.  The Company provides complete documentation to its 
customers for all regulated medical waste that it collects, including the 
name of the generator, date of pick-up and date of delivery to a treatment 
facility. The Company's documentation system meets all applicable federal, 
state and local regulations regarding the packaging and labeling of regulated 
medical waste, including, but not limited to, all relevant regulations issued 
by the U.S. Department of Transportation, OSHA and state and local 
authorities.

COMPETITION

     The regulated medical waste services industry is highly competitive, 
fragmented, and requires substantial labor and capital resources. Intense 
competition exists within the industry not only for customers but also for 
businesses to acquire. The Company's largest competitor is Browning-Ferris 
Industries, Inc. A large number of regional and local companies also compete 
in the industry. In addition, the Company faces competition from businesses 
and other organizations that are attempting to commercialize alternate 
treatment technologies or products designed to reduce or eliminate the 
generation of regulated medical waste, such as reusable or degradable medical 
products.

     The Company competes for service agreements primarily on the basis of 
cost effectiveness, quality of service, geographic location and 
generator-perceived liability risks. The Company's ability to obtain new 
service agreements may be limited by the fact that a potential customer's 
current vendor may have an excellent service history or may reduce its prices 
to the potential customer.

GOVERNMENTAL REGULATION

     The Company operates within the regulated medical waste management 
industry, which is subject to extensive and frequently changing federal, 
state and local laws and regulations. This statutory and regulatory framework 
imposes compliance burdens and risks on the Company, including requirements 
to obtain and maintain government permits. These permits grant the Company 
the authority, among other things, to construct and operate treatment and 
transfer facilities, to transport regulated medical waste within and between 
relevant jurisdictions, and to handle particular regulated substances. The 
Company's permits must be periodically renewed and are subject to 
modification or revocation by the issuing regulatory authority. In addition 
to the requirement that it obtain and maintain permits, the Company is 
subject to extensive federal, state and local laws and regulations that, 
among other things, govern the definition, generation, segregation, handling, 
packaging, transportation, treatment, storage and disposal of regulated 
medical waste. The Company is also subject to extensive regulation designed 
to minimize employee exposure to regulated medical waste. In addition, the 
Company is subject to certain foreign laws and regulations.

     FEDERAL REGULATION

     There are at least four federal agencies that have authority over 
medical waste. These agencies are the EPA, OSHA, Department of Transportation 
("DOT") and Postal Service. These agencies regulate medical waste under a 
variety of statutory and regulatory authorities.

     MEDICAL WASTE TRACKING ACT OF 1988.  In the late 1980s, the EPA 
outlined a two-year demonstration program pursuant to the Medical Waste 
Tracking Act of 1988 ("MWTA"), which was added to the Resource Conservation 
and Recovery Act of 1976 ("RCRA"). The MWTA was adopted in response to health 
and environmental concerns over infectious medical waste after medical waste 
washed ashore on beaches, particularly in New York and New Jersey during the 
summer of 1988. Public safety concerns were amplified by media reports of 
careless management of medical waste. The MWTA was intended to be the first 
step in addressing these problems. The primary objective of the MWTA was to 
ensure that regulated medical

                                       11

<PAGE>


wastes which were generated in a covered state and which posed environmental 
(including aesthetic) problems were delivered to disposal or treatment 
facilities with minimum exposure to waste management workers and the public. 
The MWTA's tracking requirements included accounting for all waste 
transported and imposed civil and criminal sanctions for violations.

     In regulations implementing the MWTA, the EPA defined regulated medical 
waste and established guidelines for its segregation, handling, containment, 
labeling and transport. Under the MWTA, the EPA was to deliver three reports 
to Congress on different aspects of regulated medical waste management and 
the success of the demonstration program for tracking regulated medical 
waste. Two of these reports were completed; the third report has not yet been 
issued. The third report is expected to cover the use of alternative medical 
waste treatment technologies, including the Company's ETD technology. There 
can be no assurance that if and when the third report is issued, it will not 
contain findings or make recommendations that are adverse to the Company's 
medical waste treatment technology. Any such adverse findings or 
recommendations could have a material adverse effect on the Company's 
business, financial condition and results of operations.

     The MWTA demonstration program expired in 1991, but the MWTA established 
a model followed by many states in developing their specific medical waste 
regulatory frameworks.

     RESOURCE CONSERVATION AND RECOVERY ACT OF 1976.  In 1976, Congress 
passed RCRA as a response to growing public concern about problems associated 
with the handling and disposal of solid and hazardous waste. RCRA required 
the EPA to promulgate regulations identifying hazardous wastes. RCRA also 
created standards for the generation, transportation, treatment, storage and 
disposal of solid and hazardous wastes, including a manifest program for the 
transportation of hazardous wastes and a permit system for solid and 
hazardous waste disposal facilities. Regulated medical wastes are currently 
considered non-hazardous solid wastes under RCRA. However, certain substances 
collected by the Company from some of its customers, including photographic 
fixer developer solutions, lead foils and amalgam, are considered hazardous 
wastes, for which the Company provides transportation services for metals 
recycling.

     DEPARTMENT OF TRANSPORTATION REGULATIONS.  The DOT has implemented 
regulations under the Hazardous Materials Transportation Authorization Act of 
1994 governing the transportation of hazardous materials, regulated medical 
waste and infectious substances. Under these regulations, the Company is 
required to package regulated medical waste in compliance with the bloodborne 
pathogens standards issued by OSHA. Under these standards, the Company must 
identify its packaging with a "biohazard" marking on the outer packaging, and 
its regulated medical waste container must be rigid, puncture-resistant, 
leak-resistant, properly sealed and impervious to moisture.

     DOT regulations also require that a transporter of hazardous substances 
be capable of responding on a 24 hour-per-day basis in the event of an 
accident, spill or release to the environment of a hazardous material. The 
Company has entered into an agreement with CHEMTREC, an organization that 
provides 24-hour emergency spill coverage in the United States and Canada, to 
provide spill cleanup services in all of the Company's service areas.

     The Company's drivers are specifically trained on topics such as safety, 
hazardous materials, specifically-regulated medical waste, hazardous 
chemicals and infectious substances. Employees are trained to deal with 
emergency situations including spills, accidents and releases in to the 
environment, and the Company has a written contingency plan for these events. 
The Company's vehicles are outfitted with spill control equipment and the 
drivers are trained in their use.

     COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION AND LIABILITY ACT OF 
1980.  The Comprehensive Environmental Response, Compensation and Liability 
Act of 1980 ("CERCLA") established a regulatory and remedial program to 
provide for the investigation and clean-up of facilities from which there has 
been an actual or threatened release of hazardous substances into the 
environment. CERCLA and similar state laws, impose strict, joint and several 
liability on the current and former owners and operators of

                                       12

<PAGE>


facilities from which releases of hazardous substances have occurred and on 
the generators and transporters of the hazardous substances that come to be 
located at such facilities. Responsible parties may be liable for substantial 
waste site investigation and clean-up costs and natural resource damages, 
regardless of whether they exercised due care and complied with applicable 
laws and regulations. If the Company were found to be a responsible party for 
a particular site, it could be required to pay the entire cost of waste site 
investigation and clean-up, even though other parties also may be liable. The 
Company's ability to obtain contribution from other responsible parties may 
be limited by the Company's inability to identify those parties and by their 
financial inability to contribute to investigation and clean-up costs.

     The Company utilizes landfills for disposal of treated regulated medical 
waste from three of its facilities. Following treatment by the Company, the 
waste is considered non-hazardous solid waste. Non-hazardous solid waste is 
not regulated as hazardous unless it has been contaminated with a hazardous 
substance. The Company employs quality control measures to check incoming 
regulated medical waste for hazardous substances. Customer contracts also 
require the exclusion of hazardous substances or radioactive materials from 
the regulated medical waste. Separate customer contracts govern the Company's 
transportation for recycling of limited quantities of its customers' 
hazardous substances.

     OCCUPATIONAL SAFETY AND HEALTH ACT OF 1970.  The Occupational Safety and 
Health Act of 1970 authorizes OSHA to promulgate occupational safety and 
health standards. Various standards apply to certain aspects of the Company's 
operations. These standards include rules governing exposure to bloodborne 
pathogens and other potentially infectious materials, lock out/tag out 
procedures, medical surveillance requirements, use of respirators and 
personal protective equipment, emergency planning, hazard communication, 
noise, ergonomics, and forklift safety, among others. OSHA regulations are 
designed to minimize the exposure of employees to hazardous work 
environments. The Company is subject to unannounced safety inspections at any 
time. Employees are required by Company policy to receive new employee 
training, annual refresher training and training in their specific tasks. As 
part of the Company's medical surveillance program, employees receive 
pre-employment physicals, including drug testing, annually-required medical 
surveillance and exit physicals. The Company also subscribes to a drug-free 
workplace policy.

     UNITED STATES POSTAL SERVICE.  The Company was required to obtain a 
permit from the U. S. Postal Service to conduct its "mail-back" program, 
pursuant to which customers mail appropriately packaged sharps containers 
directly to the Company's treatment facilities.

     STATE AND LOCAL REGULATION

     The Company currently conducts some type of business activity in 32 
states. These activities include the collection, transportation, processing, 
transferring or recycling of regulated medical waste and, in some cases, 
hazardous substances. Each state has its own regulations related to the 
handling, treatment and storage of regulated medical waste. Although there 
are many differences among the various state laws and regulation, many states 
have followed the regulated medical waste model under the MWTA and are 
implementing programs under RCRA. Regulations cover the Company's 
transportation of regulated medical waste both intrastate and interstate. In 
each of the states where the Company operates a treatment facility or 
transfer station, it is required to comply with numerous state and local laws 
and regulations as well as its site-specific operating plan. Agencies writing 
regulations at the state level typically include departments of health and 
state environmental protection agencies. In addition, many municipalities 
have ordinances, local laws and regulations affecting the Company's 
operations, including but not limited to zoning and health measures.

     In recent years, a number of communities have instituted "flow control" 
requirements, which typically require that waste collected within a 
particular area be deposited at a designated facility. In May 1994, the U.S. 
Supreme Court ruled that a flow control ordinance was inconsistent with the 
Commerce Clause of the Constitution of the United States. A number of lower 
federal courts have struck down similar measures. The Company believes that 
the U.S. Congress may consider  bills that could at least partially overturn 
these court decisions and immunize particular governmental actions from 
Commerce Clause scrutiny.

                                       13

<PAGE>

     Similarly, the U. S. Supreme Court has consistently held that state and 
local measures that seek to restrict the importation of extraterritorial 
waste or tax imported waste at a higher rate are unconstitutional. To date, 
congressional efforts to enable states, under certain circumstances, to 
impose differential taxes on out-of-state waste or restrict waste importation 
have been unsuccessful.

     In the absence of federal legislation, certain local laws that direct 
waste flows to designated facilities may be unenforceable, and discriminatory 
taxes and waste importation restrictions should continue to be subject to 
judicial invalidation. If the U. S. Congress adopts legislation allowing for 
certain types of flow control or restricting the importation of waste, or if 
legislation affecting interstate transportation of waste is adopted at the 
federal or state level, such legislation could adversely affect the Company's 
medical waste collection, transport, treatment and disposal operations and 
hence would have a material adverse effect on the Company's business, 
financial condition and results of operations.

     States predominantly regulate medical waste as a solid or "special" 
waste and not as a hazardous waste under RCRA. State definitions of medical 
waste include, but are not limited to: microbiological waste (cultures and 
stocks of infectious agents); pathology waste (human body parts from surgical 
and autopsy waste); blood and blood products; and sharps.

     Most states require segregation of different types of regulated medical 
waste at the point of generation. A majority of states require that the 
universal biohazard symbol or related label appear on medical waste 
containers. Storage regulations may apply to the generator, the treatment 
facility, the transport vehicle, or all three. Storage rules center on 
identifying and securing the storage area for public safety as well as 
setting standards for the manner and length of storage. Many states mandate 
employee training for safe environmental clean-up through emergency spill and 
decontamination plans. Many states mandate that transporters carry spill 
equipment in their vehicles. Those states whose regulatory framework relies 
on the MWTA model have tracking document systems in place.

     In the State of Washington, the Company is subject to regulation by the 
Utilities and Transportation Commission, which regulates all businesses 
engaged in transportation in the state. As a regulated business, the Company 
must receive approval from the Utilities and Transportation Commission for 
the prices that it charges for its services in Washington.

     The Company maintains numerous permits and licenses to conduct its 
business from various state and local authorities. The Company's permits vary 
from state to state based upon the Company's activities within that state and 
on the applicable state and local laws and regulations. These permits include 
transport permits for solid waste, regulated medical waste and hazardous 
substances, permits to construct and operate treatment facilities, permits to 
construct and operate transfer stations, permits governing discharge of 
sanitary water and registration of equipment under air regulations, specific 
approval for the use of ETD to treat regulated medical waste, a bulk pool 
irradiator operator's license for the Company's currently inactive irradiator 
at its West Memphis, Arkansas facility, and various business operator's 
licenses. The Company believes that it is in substantial compliance with all 
applicable state and local laws and regulations.

     The Company's treatment technology is an alternative to the conventional 
treatment technologies of incineration and autoclaving and has not been 
approved in all states for the treatment of regulated medical waste. The 
Company has been permitted to operate its treatment technology in 13 states 
with additional applications pending. There can be no assurance, however, 
that the Company's treatment technology will be approved for the treatment of 
regulated medical waste in each state or other jurisdiction where the Company 
may seek regulatory approval in the future to construct and operate a 
treatment facility. The Company's inability to obtain any such regulatory 
approval could have a material adverse effect on the Company's business, 
financial condition and results of operations.

                                       14

     FOREIGN REGULATION

     The Company presently conducts business in  British Columbia, Canada, 
where it collects regulated medical waste in the Vancouver area and 
transports it to the Company's Morton, Washington, treatment facility. The 
Company's activities in British Columbia are governed at the federal level by 
the Canadian Transportation of Dangerous Goods Act, 1992, and at the 
provincial level by the British Columbia Waste Management Act. The federal 
Transportation of Dangerous Goods Act, 1992, regulates the movement of 
dangerous goods, including infectious substances and other "specified 
dangerous goods," by all modes of transportation, and imposes joint and 
several liability on all persons who are responsible for, or who caused or 
contributed to, the release of any "specified dangerous good" into the 
environment. Any business engaged in a regulated activity is presumed to be 
liable for any such release, unless the business can demonstrate that it 
acted reasonably. The provincial Waste Management Act regulates the storage, 
transportation and disposal of waste, including biomedical waste, and imposes 
strict, joint and several liability for all clean-up costs associated with 
the release of hazardous substances into the environment. The Company has 
obtained all permits required by these two acts. There can be no assurance, 
however, that the Company will not be required in the future to pay for waste 
clean-up costs incurred under either act on a joint and several basis.

     The Company also conducts business in Mexico through its joint venture, 
Medam, which plans to collect regulated medical waste and transport it for 
treatment to a new facility close to Mexico City. See "Growth Strategy--Other 
Growth Opportunities."

     If the Company expands its operations into other foreign jurisdictions, 
it will be required to comply with the laws and regulations of each such 
jurisdiction.

     PERMITTING PROCESS

     Each state in which the Company operates, and each state in which the 
Company may operate in the future, has a specific permitting process. After 
the Company has identified a geographic area in which it wishes to locate a 
treatment or transfer facility, the Company identifies one or more locations 
for a potential new site. Typically, the Company will develop a site 
contingent on obtaining zoning approval and local and state operating 
authority. Most communities rely on state authorities to provide operating 
rules and safeguards for their community. Usually the state provides public 
notice of the project and, if a sufficient threshold of public interest is 
shown, a public hearing may be held. If the Company is successful in meeting 
all regulatory requirements, the state may issue a permit to construct the 
treatment facility or transfer station. Once the facility is constructed, the 
state may again issue public notice of its intent to issue an operating 
permit and provide an opportunity for public opposition or other action that 
may impede the Company's ability to construct or operate the planned facility.

     The Company has been successful in obtaining permits for its current 
regulated medical waste transfer, treatment and processing facilities and for 
its transportation operations. Several of the Company's past attempts to 
construct and operate regulated medical waste treatment facilities, however, 
have met with significant community opposition. In some of these cases, the 
Company has withdrawn from the permitting process. Permitting for 
transportation operations frequently involves registration of vehicles, 
inspection of equipment and background investigations on the Company's 
officers and directors.

     POTENTIAL LIABILITY AND INSURANCE

     The regulated medical waste management industry involves potentially 
significant risks of statutory, contractual, tort and common law liability. 
Potential liability could involve, for example, claims for clean-up costs, 
personal injury or damage to the environment, claims of employees, customers 
or third parties for personal injury or property damages occurring in the 
course of the Company's operations, or claims alleging negligence or 
professional errors or omissions in the planning or performance of work. The 
Company could also be subject to fines in connection with violations of 
regulatory requirements.

                                       15

<PAGE>

     The Company carries liability insurance coverage which it considers 
sufficient to meet regulatory and customer requirements and to protect the 
Company's employees, assets and operations. The availability of liability 
insurance within the regulated medical waste industry has been adversely 
affected by the constrained market for environmental liability and other 
insurance. More aggressive enforcement of environmental and management 
regulations, as well as legal decisions and judgments adverse to companies 
exposed to pollution damage claims, could lead to a substantial reduction in 
the availability and extent of insurance coverage. In the future, insurance 
may be vailable only at significantly increased premiums with less extensive 
coverage. If the Company is unable to obtain adequate insurance coverage at a 
reasonable cost, it may become exposed to potential liability claims. In this 
event, a successful claim of sufficient magnitude could have a material 
adverse effect on the Company's business, financial condition and results of 
operations.

     CERCLA and similar state statutes impose strict, joint and several 
liability on the present and former owners and operators of facilities from 
which releases of hazardous substances have occurred and on the generators 
and transporters of the hazardous substances that come to be located at such 
facilities. Responsible parties may be liable for waste site investigation, 
waste site clean-up costs and natural resource damages, which costs could be 
substantial, regardless of whether they exercised due care and complied with 
all relevant laws and regulations. There can be no assurance that the Company 
will not face claims under CERCLA or similar state laws resulting in 
substantial liability for which the Company is uninsured and which could have 
a material adverse effect on the Company's business, financial condition and 
results of operations. The Company's pollution liability insurance excludes 
liabilities under CERCLA.

PATENTS AND PROPRIETARY RIGHTS

     The Company considers the protection of its technology relating to the 
processing of regulated medical waste to be material to its business. The 
Company's policy is to protect its technology by a variety of means, 
including applying for patents in the United States and in appropriate 
foreign countries.

     The Company holds nine United States patents and an  additional patent 
application pending in the United States relating to the ETD treatment 
process and other aspects of processing regulated medical waste. The Company 
has filed counterpart patent applications in several foreign countries and 
has received patents in Russia, Hungary, Canada, Mexico and Australia. The 
Company also holds one United States patent for its reusable container, used 
under the trademark STERI-TUB-Registered Trademark-.

     In November 1995, the Company entered into a cross-license agreement 
with IIT Research Institute ("IITRI"). Under this agreement, IITRI granted to 
the Company a royalty-free exclusive license in North America, Europe, Japan 
and other industrialized countries throughout the world to use and 
commercialize certain patent rights and know-how held by IITRI relating to 
the use of radio-frequency technology in the treatment of regulated medical 
waste, and the Company granted to IITRI a royalty-free exclusive license in 
the remaining countries of the world to use and commercialize certain 
corresponding patent rights and know-how held by the Company. The agreement 
continues until the expiration of the last-to-expire of any of the subject 
patents held by either IITRI or the Company.

     An issued patent grants to the owner the right to exclude others from 
practicing the inventions claimed in the patent. In the United States, a 
patent filed before June 8,1995 is enforceable for 17 years from the date of 
issuance or 20 years from the effective date of filing, whichever is longer. 
Patents issued on applications filed on or after June 8, 1995 expire 20 years 
from the effective date of filing. The last-to-expire of the Company's 
existing United States patents relating to its ETD treatment process will 
expire in January 2015.

     In addition, the Company has additional proprietary technology relating 
to the processing of regulated medical waste that the Company believes is 
patentable. The Company has chosen, however, not to file for patent 
protection for this technology at this time.

                                       16

<PAGE>


     There can be no assurance that any claims which are included in pending 
or future patent applications will be issued, that any issued patents will 
provide the Company with competitive advantages or will not be challenged by 
third parties or that the existing or future patents of third parties will 
not have an adverse effect on the ability of the Company to carry out its 
business. In addition, there can be no assurance that other companies will 
not independently develop similar processes or engineer around patents that 
may have been issued to the Company. Litigation or administrative proceedings 
may be necessary to enforce the patents issued to the Company or to determine 
the scope and validity of others' proprietary rights. Any litigation or 
administrative proceeding could result in substantial cost to the Company and 
distraction of the Company's management. An adverse ruling in any litigation 
or administrative proceeding could have a material adverse effect on the 
Company's business, financial condition and results of operations.

     The commercial success of the Company will also depend in part upon the 
Company's not infringing patents issued to competitors. There can be no 
assurance that patents belonging to competitors will not require the Company 
to alter its processes, pay licensing fees or cease development of its 
current or future processes. Litigation or administrative proceedings may be 
necessary to enforce the patents issued to the Company or to determine the 
scope and validity of others' proprietary rights. Any litigation or 
administrative proceeding could result in substantial cost to the Company and 
distraction of the Company's management. An adverse ruling in any litigation 
or administrative proceeding could have a material adverse effect on the 
Company's business, financial condition and results of operations. In 
addition, there can be no assurance that the Company would be able to license 
the technology rights that it may require at a reasonable cost or at all. 
Failure by the Company to obtain a license to any technology that the Company 
currently uses to process regulated medical waste would have a material 
adverse effect on the Company's business, financial condition and results of 
operations. In addition, to determine the priority of inventions or patent 
applications the Company may have to participate in interference proceedings 
declared by the U.S. Patent and Trademark Office or in proceedings before 
foreign agencies, any of which would result in substantial costs to the 
Company and distraction of the Company's management.

     The Company holds federal registrations of the trademarks "Steri-Fuel," 
"Steri-Plastic," "Steri-Tub" and "Steri-Cement" and the service marks 
"Stericycle" and a mark consisting of a graphic the Company uses in 
association with its name and services in the United States. There can be no 
assurance that the registered or unregistered trademarks or service marks of 
the Company will not infringe upon the rights of third parties. The 
requirement to change any trademark, service mark or trade name of the 
Company would result in the loss of any goodwill associated with that 
trademark, service mark or trade name and could entail significant expense.

     The Company also relies on unpatented and unregistered trade secrets, 
trademarks, proprietary know-how and continuing technological innovation that 
it seeks to protect, in part, by confidentiality agreements with its 
employees, vendors and consultants. There can be no assurance that these 
agreements will not be breached, that the Company would have adequate 
remedies for any breach or that the Company's trade secrets or know-how will 
not otherwise become known or independently discovered by third parties.

EMPLOYEES

     At December 31, 1997, the Company employed 378 full-time employees and 
128 part-time employees engaged primarily in sales and marketing.

     The Company's production and maintenance employees at its Morton, 
Washington facility have voted to affiliate with the International 
Brotherhood of Teamsters, AFL-CIO. The Company will be required to negotiate 
a collective bargaining agreement covering these employees. None of the 
Company's other employees is covered by a collective bargaining agreement. 
The Company considers its employee relations generally to be satisfactory.

ITEM 2.  FACILITIES

     The Company leases office space for its corporate offices in Deerfield, 
Illinois. The Company owns and operates ETD treatment facilities in Morton, 
Washington and Yorkville, Wisconsin. It leases a treatment facility in 
Woonsocket, Rhode Island which the Company has an option to purchase for 
$2,000 upon the expiration of the lease in June 2017. The Company also leases 
a building in Loma Linda, California which  is used as an ETD treatment 
facility, and subleases incineration or autoclave facilities from WMI in 
Terrell, Texas, Baltimore, Maryland and Henderson, Colorado and may enter 
into a sublease from WMI for its facility in Chandler, Arizona if and when 
the necessary landlord consents and regulatory approvals have been obtained. 
The Company also owns and operates a recycling and research development 
facility in West Memphis, Arkansas.

     The Company leases two permitted transfer stations in California, one at 
San Leandro and the other in Valencia, and one in New York, New York. The 
Company also utilizes transfer stations in Columbus and Monroe, Ohio. In 
Haverhill, Massachusetts and Vancouver, British Columbia the Company utilizes 
facilities owned by third parties licensed to operate transfer stations. In 
addition, all of the Company's treatment facilities are authorized to 
transfer regulated medical waste. The Company also leases sales and customer 
service centers in Kirkland, Washington, Salem, New Hampshire, Anaheim, 
California and Middletown, Connecticut, and a depot in Valparaiso, Indiana.

     The Company's lease of its treatment facility at Woonsocket, Rhode 
Island expires in June 2017 upon the maturity of the last to mature of the 
industrial development revenue bonds which were issued to finance the 
acquisition and equipping of the facility. The Company's leasehold interest 
in the facility and the Company's machinery and equipment at the facility are 
pledged as collateral to secure the Company's obligations in connection with 
these bonds. As noted, the Company has an option to purchase the facility for 
$2,000 upon the repayment of all of the bonds. The Company's machinery and 
equipment at its Yorkville, Wisconsin treatment facility are leased under an 
equipment lease expiring in February 1999 and are pledged as collateral to 
secure the Company's obligations under the lease. Substantially all of the 
Company's property and equipment provide collateral for the Company's 
obligations under its revolving credit facility with Silicon Valley Bank. The 
Company believes that its existing facilities are generally adequate for its 
current needs.

ITEM 3.   LEGAL PROCEEDINGS

     The Company operates in a highly competitive industry and may be exposed 
to regulatory inquiries or investigations from time to time. Investigations 
can be initiated for a variety of reasons. The Company has been involved in 
several legal and administrative proceedings that have been settled or 
otherwise resolved on terms acceptable to the Company, without having a 
material adverse effect on the Company's business, financial condition or 
results of operations. From time to time the Company may consider it more 
cost-effective to settle such proceedings than to involve itself in costly 
and time-consuming administrative actions or litigation. The Company is also 
a party to various legal proceedings arising in the ordinary course of its 
business. The Company believes that the resolution of these other matters 
will not have a material adverse effect on the Company's business, financial 
condition or results of operations.

ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matter was submitted to a vote of the Company's stockholders during 
the fourth quarter of the fiscal year ended December 31, 1997.

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

     THE FOLLOWING DISCUSSION OF THE FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF THE COMPANY SHOULD BE READ IN CONJUNCTION WITH THE COMPANY'S
CONSOLIDATED FINANCIAL STATEMENTS AND RELATED NOTES IN ITEM 8 OF THIS REPORT.

BACKGROUND

     The Company was incorporated in March 1989. The Company provides 
regulated medical waste collection, transportation, treatment, disposal, 
reduction, reuse and recycling services to its customers, together with 
related training and education programs and consulting services. The Company 
also sells ancillary supplies and transports pharmaceuticals, photographic 
chemicals, lead foil and amalgam for recycling in selected geographic service 
areas. As part of its recycling services, the Company supplies recycled 
treated medical waste plastics to a plastics manufacturer and supplies 
treated medical waste as a refuse-derived fuel for use in the production of 
electricity.

     The Company's revenues have increased from $1,563,000 in 1991 to 
$46,166,000 in 1997. The Company derives its revenues from services to two 
principal types of generators of regulated medical waste: (i) hospitals, 
blood banks and pharmaceutical manufacturers ("Core" generators) and (ii) 
long-term and subacute care facilities, outpatient clinics, medical and 
dental offices, industrial clinics, dialysis centers, laboratories, 
biotechnology and biomedical companies, veterinary offices, municipal health 
departments, ambulance, fire and police departments, correctional facilities, 
schools and park districts and funeral homes ("Alternate Care" generators). 
Substantially all of the Company's services are provided pursuant to customer 
contracts specifying either scheduled or on-call regulated medical waste 
management services, or both. Contracts with hospitals and other Core 
generators, which may run for more than one year, typically include price 
escalator provisions which allow for price increases generally tied to an 
inflation index or set at a fixed percentage. Contracts with Alternate Care 
generators generally provide for annual price increases and have an automatic 
renewal provision unless the customer notifies the Company prior to 
completion of the contract. As of December 31, 1997, the Company had over 
41,000 customers.

     As part of the Company's marketing strategy, the Company offers 
reduction, resource recovery and recycling services to customers. 
Accordingly, the Company has invested funds to treat and recover the plastics 
from single-use products, and as a part of that strategy, the Company has 
entered into an agreement with a plastic products manufacturer to provide 
recycled regulated medical waste plastics for use in a line of medical waste 
sharps containers. The Company has delivered the recycled plastics as 
required under the agreement as part of the Company's commitment to provide 
environmentally sound alternatives to other regulated medical waste treatment 
methods. The demand for recycled treated regulated medical waste plastics is 
currently limited.

     In 1994, as a result of increasing demand for customer service from the 
growing number of Alternate Care generators, the Company began implementing a 
transition from the use of a national contract carrier to its own 
transportation of regulated medical waste. The Company has obtained its own 
permits, hired and trained its own drivers, purchased or leased its own 
trucks and trailers and obtained approvals for and opened transfer stations. 
The Company believes that since it has assumed control of transportation, it 
has been able to improve service levels, equipment utilization and route 
density and provide more efficient dispatching.

     The Company expenses as incurred all permitting, design and start-up 
costs associated with all of its facilities. The Company elects to expense 
rather than to capitalize the costs of obtaining permits and approvals for 
each proposed facility regardless of whether the Company is ultimately 
successful in obtaining the desired permits and approvals and developing the 
facility. The Company recognizes as a current expense all legal fees and 
other costs related to obtaining and maintaining permits and approvals. In 
addition, the Company expenses all costs related to research and development 
as incurred.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER  31, 1996

     REVENUES.  Revenues increased $21,624,000, or 88.1%, to $46,166,000 
during the year ended December 31, 1997 from $24,542,000 during the year 
ended December 31, 1996 as the Company continued to implement its strategy of 
focusing on higher-margin Alternate Care generators while simultaneously 
paring certain higher-revenue but lower-margin accounts with Core generators. 
This increase also reflects the inclusion of a full year's revenues from the 
Waste Management, Inc. ("WMI") acquisition completed in December 1996, eight 
months of revenues from the Environmental Control Co, Inc. ("ECCO") 
acquisition completed in May 1997, and partial years' revenues from  various 
other smaller acquisitions. For the year, internal sales growth for Alternate 
Care generators was 13%, while sales to Core generators decreased by 4%. 
Incremental revenues during 1997 attributable to acquisitions completed in 
1997 and late 1996 were $20,975,000. Excluding these incremental revenues 
from acquisitions, revenues increased from $24,542,000 in 1996 to $25,191,000 
in 1997, or 2.6%.

     COST OF REVENUES.  Cost of revenues increased $14,686,000, or 75.6%, to 
$34,109,000 during the year ended December 31, 1997 from $19,423,000 during 
the year ended December 31, 1996. The principal reasons for the increase were 
higher transportation, treatment and disposal costs as a result of the higher 
volume attributable to the Company's acquisitions and integration expenses 
related to the Company's expansion into new geographic service areas. The 
gross margin percentage increased to 26.1% during 1997 from 20.9% during 
1996, due to the continuing shift to Alternate Care customers and leveraging 
of the Company's treatment capacity.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and 
administrative expenses increased to $10,671,000 during the year ended 
December 31, 1997 from $7,556,000 during the year ended December 31, 1996. 
The increase was largely the result of increases in selling and marketing 
expenses as a result of the Company's acquisitions and expansion of the sales 
network, and increased administrative costs related the higher volume. 
Selling, general and administrative expenses as a percentage of revenues 
decreased to 23.1% during 1997 from 30.8% during 1996 due to improved 
leverage of the administrative structure versus the sales growth.

     INTEREST EXPENSE AND INTEREST INCOME.  Interest expense increased  to 
$428,000 during the year ended December 31, 1997 from $373,000 during the 
year ended December 31, 1996. This increase was primarily attributable to 
higher indebtedness related to the WMI and ECCO acquisitions.   Interest 
income increased to $618,000 during 1997 from $421,000 during 1996 due to 
interest earned on the invested cash proceeds from the Company's initial 
public offering ("IPO") in August 1996.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995

     REVENUES.  Revenues increased $3,203,000, or 15%, to $24,542,000 during 
the year ended December 31, 1996 from $21,339,000 during the year ended 
December 31, 1995 as the Company continued to implement its strategy of 
focusing on higher-margin Alternate Care generators while simultaneously 
paring certain higher-revenue but lower-margin accounts with Core generators. 
This increase also reflects the inclusion of a full year's revenues from the 
Safetech Health Care, Inc. ("Safetech") acquisition, which was completed in 
June 1995, eleven months of revenues from the WMI Medical Services of New 
England, Inc. ("WMI-NE") acquisition, which was completed in January 1996, 
and eight months of revenues from the Doctors Environmental Control, Inc. 
("DEC") and Sharps Incinerator of Fort, Inc. ("Sharps") acquisitions, both of 
which were completed in May 1996, and the inclusion of revenues for the last 
10 days of 1996 resulting from the Company's purchase in December 1996 of a 
major portion of WMI's  regulated medical waste business . The increase in 
revenues was partially offset by a decline in revenues attributable to a lack 
of any miscellaneous product sales during 1996 and the sale in April 1995 of 
certain unprofitable customer accounts and related assets obtained through 
acquisitions. Incremental revenues during 1996 attributable to acquisitions 
completed in 1995 and 1996 were $2,332,000. Excluding these incremental 
revenues from acquisitions, revenues increased from $21,339,000 in 1995 to 
$22,210,000 in 1996, or 4.1%.

                                       24

     COST OF REVENUES.  Cost of revenues increased $1,945,000, or 11.1%, to 
$19,423,000 during the year ended December 31, 1996 from $17,478,000 during 
the year ended December 31, 1995. The principal reasons for the increase were 
higher transportation, treatment and disposal costs as a result of the 
Safetech, WMI-NE, DEC, Sharps and WMI acquisitions and start-up expenses 
related to the Company's expansion into new geographic service areas. The 
gross margin percentage increased to 20.9% during 1996 from 18.1% during 
1995, due to the continued increase in Alternate Care customers and 
leveraging of the treatment capacity.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and 
administrative expenses decreased to $7,556,000 during the year ended 
December 31, 1996 from $8,137,000 during the year ended December 31, 1995. 
This decrease was primarily attributable to a reduction in expenditures to 
develop treated medical waste as an alternate fuel for the production of 
cement and to savings from the integration into the Company's operations of 
the Safe Way Disposal Systems, Inc. ("Safe Way") acquisition in 1994. These 
savings resulted from the elimination of redundant employee and staff 
positions and the reallocation of resources to Alternate Care generators. In 
addition, corporate costs and permitting expenses were at lower levels during 
1996 than they were during 1995. Selling, general and administrative expenses 
as a percentage of revenues decreased to 30.8% during 1996 from 38.1% during 
1995.

     INTEREST EXPENSE AND INTEREST INCOME.  Interest expense increased to 
$373,000 during the year ended December 31, 1996 from $277,000 during the 
year ended December 31, 1995. This increase was primarily attributable to 
higher indebtedness under the Company's revolving credit facility and 
interest expense on notes issued for acquisitions. Interest income increased 
to $421,000 during 1996 from $9,000 during 1995 due to interest earned on the 
invested cash proceeds from the Company's IPO in August 1996.

LIQUIDITY AND CAPITAL RESOURCES

     The Company has been financed principally through the sale of stock to 
investors. Prior to the Company's IPO, purchasers of stock invested more than 
$50,137,000 in capital which has been used to fund research and development, 
acquisitions, capital expenditures, ongoing operating losses and working 
capital requirements. The Company's IPO in August 1996 raised $31,050,000, 
excluding offering costs, which has been or will be used primarily to fund 
acquisitions and for general working capital. The Company has also been able 
to secure plant and equipment leasing or financing in connection with some of 
its facilities. These debt facilities are secured by security interests in 
the financed assets. In addition, during 1995 the Company was able to obtain 
a $2,500,000 revolving line of credit secured by accounts receivable and a 
secured interest in all other assets of the Company. In March 1998, the 
Company increased its revolving line of credit to $7,500,000.

     During 1995 the Company's stockholders approved a plan of 
recapitalization, pursuant to which all of the Company's outstanding shares 
of preferred stock were reclassified as shares of common stock. As a result, 
the Company was able to eliminate any liability for accrued but unpaid 
dividends on its preferred stock and the preferential rights on liquidation 
of holders of preferred stock.

     At December 31, 1997, the Company's working capital was $7,214,000 
compared to $14,617,000 and $439,000 at December 31, 1996 and 1995, 
respectively. The decrease versus 1996 was primarily due to  lower balances 
of cash, cash equivalents and short-term investments, which decreased by 
$10,040,000 to finance acquisitions partially offset by other working capital 
needs. The increase in the 1996 working capital compared to 1995 was due to 
higher cash balances shortly after the Company's IPO offset by an increase in 
debt as a result of the WMI acquisition in December 1996.

     The Company's other financial obligations include industrial development 
revenue bonds issued on behalf of and guaranteed by the Company to finance 
its Woonsocket, Rhode Island treatment facility and equipment. These bonds, 
which had an outstanding aggregate balance of $1,358,000 as of December 31, 
1997 at fixed interest rates ranging from 6.00% to 7.375%, are due in various 
amounts through June 2017. In addition, the Company issued various promissory 
notes in connection with acquisitions during 1997, primarily a 10-year note 
for $2,300,000 as part of the ECCO acquisition.

                                       25

    Net income (loss) before depreciation and amortization increased to a 
surplus of $4,508,000 during the year ended December 31, 1997, compared to a  
deficit of $325,000 during the year ended December 31, 1996. Cash used in 
operations was $100,000 during the year ended December 31, 1997, compared to 
cash provided by operations of $57,000 during the year ended December 31, 
1996 and cash used in operations of $871,000 during the year ended December 
31, 1995. The change primarily reflects the Company's profitability in 1997 
offset by a higher working capital investment in receivables.

     Net cash used in investing activities was $3,323,000 during the year 
ended December 31, 1997 compared to $13,310,000 during the year ended 
December 31, 1996. The decrease in 1997 was the result of  a $5,552,000  
investment in ECCO and smaller acquisitions and joint ventures, offset by net 
proceeds from short-term investments of $3,464,000 in 1997 versus purchases 
of $5,799,000 in short-term investments in 1996.  Capital expenditures for 
the year ended December 31, 1997 were $1,235,000, primarily for improvements 
to existing facilities, containers and transportation equipment. Capital 
expenditures were $995,000 in 1996 and $726,000 in 1995. The Company did not 
open any new treatment facilities during 1997. The Company may decide to 
build additional  treatment facilities as volumes increase in the Company's 
current geographic services areas or as the Company enters new areas. The 
Company also may elect to increase capacity in its existing treatment 
facilities, which would require additional capital expenditures. In addition, 
capital requirements for transportation equipment will continue to increase 
as the Company grows. The amount and level of these expenditures cannot be 
determined currently as they will depend upon the nature and extent of the 
Company's growth and acquisition opportunities. The Company believes that its 
cash, cash equivalents, short-term  investments, revolving bank line and cash 
from operations will fund its capital requirements through 1998.

     Net cash used in financing activities was $3,153,000 during the year 
ended December 31, 1997 compared to net cash provided by financing activities 
of $25,065,000 during the year ended December 31, 1996. The change was the 
result of $28,535,000 of proceeds received in 1996 primarily from the 
Company's IPO and repayments in 1997 of $2,905,000 in long-term debt relating 
primarily to a note issued in connection with the December 1996 WMI 
acquisition.

     In 1997, cash and cash equivalents decreased by $6,576,000 primarily due 
to investment/acquisition  activities of $3,323,000 and repayments of notes 
and leases of $3,153,000.    

YEAR 2000 ISSUES

     The Company has developed a plan to modify its information technology to 
be ready for the Year 2000 and has begun converting critical data processing 
systems. The Company currently expects the project to be substantially 
complete by June 1999 at a cost not material to the Company's business. This 
cost includes internal costs but excludes the cost to upgrade and replace 
data processing systems in the normal course of business. The Company does 
not expect this project to have a significant effect on operations. As of 
December 31, 1997, there had been no amounts expensed in converting the 
Company's data processing systems to be ready for the Year 2000. The Company 
will continue to implement systems with strategic value focused on logistics 
and further integration of the Company's business functions.

                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                 DECEMBER 31, 1997

NOTE 1--DESCRIPTION OF BUSINESS

     Stericycle, Inc. (the "Company") was incorporated in Delaware in March 
1989 for the purpose of providing collection, transportation, treatment, 
disposal, reduction, reuse and recycling services for regu-lated medical 
waste to hospitals and other healthcare providers in the United States and 
Canada.

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION:

     The consolidated financial statements include the accounts of 
Stericycle, Inc. and its wholly-owned subsidiaries, Stericycle of Arkansas, 
Inc., Stericycle of Washington, Inc., SWD Acquisition Corporation and 
Environmental Control Co., Inc. All significant intercompany accounts and 
transactions have been eliminated.

REVENUE RECOGNITION:

     The Company recognizes revenue when the treatment of the regulated 
medical waste is completed on-site or the waste is shipped off-site for 
processing and disposal. For waste shipped off-site, all associ-ated costs 
are recognized at time of shipment.

CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS:

     The Company considers all highly liquid instruments with a maturity of 
less than three months when purchased to be cash equivalents. Short-term 
investments consist of highly liquid investments in corporate debt 
obligations which mature in less than one year and are classified as 
held-to-maturity since management has the positive intent and ability to hold 
the securities to maturity. These obligations are stated at amortized cost, 
which approximates fair market value. Interest income is recognized as earned.

PROPERTY, PLANT AND EQUIPMENT:

     Property, plant and equipment are stated at cost. Depreciation and 
amortization, which include the depreciation of assets recorded under capital 
leases, are computed using the straight-line method over the estimated useful 
lives of the assets as follows:

          Buildings and improvements--10 to 30 years

          Machinery and equipment--3 to 10 years

          Office equipment and furniture--5 to 10 years

GOODWILL:

     Goodwill is amortized using the straight-line method over 25 years. 
Amortization expense for 1995, 1996 and 1997 related to goodwill was 
approximately $320,000, $390,000 and $1,042,000, respectively. The Company 
continually evaluates the value and future benefits of its goodwill. The 
Company assesses re-

                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                 DECEMBER 31, 1997

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

coverability from future operations using income from operations of the 
related acquired business as a measure. Under this approach, the carrying 
value of goodwill would be reduced if it becomes probable that the Company's 
best estimate for expected undiscounted future cash flows of the related 
business would be less than the carrying amount of goodwill over its 
remaining amortization period. For the three-year period ended December 31, 
1997, there were no adjustments to the carrying amounts of goodwill resulting 
from these evaluations.

NEW PLANT DEVELOPMENT AND PERMITTING COSTS:

     The Company expenses costs associated with the operations of new plants 
prior to the commencement of services to customers and all initial and 
on-going costs related to permitting.

RESEARCH AND DEVELOPMENT COSTS:

     The Company expenses costs associated with research and development as 
incurred. Research and development expense for 1995, 1996 and 1997 was 
$975,000, $194,000 and $281,000, respectively.

INCOME TAXES:

     Deferred income taxes reflect the net tax effects of temporary 
differences between the carrying amounts of assets and liabilities for 
financial reporting purposes and the amounts used for income tax purposes. 
Deferred tax liabilities and assets are determined based on the differences 
between the financial statement and tax bases of assets and liabilities using 
enacted tax rates in effect for the year in which the differences are 
expected to reverse.

FINANCIAL INSTRUMENTS:

     The Company's financial instruments consist of cash and cash 
equivalents, short-term investments, accounts receivable and payable and 
long-term debt. The fair values of these financial instruments were not 
materially different from their carrying values. Financial instruments which 
potentially subject the Company to concentrations of credit risk consist 
principally of accounts receivable. Credit risk on trade receivables is 
minimized as a result of the large size of the Company's customer base. No 
single customer represents greater than 10% of total accounts receivable. The 
Company performs ongoing credit evaluation of its customers and maintains 
allowances for potential credit losses. These losses, when incurred, have 
been within the range of management's expectations.

USE OF ESTIMATES:

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

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

NET INCOME (LOSS) PER COMMON SHARE:

     In 1997, the Financial Accounting Standards Board ("FASB") issued 
Statement of Financial Account-ing Standards No. 128, "Earnings per Share" 
("FAS 128"). FAS 128 replaced the calculation of primary and fully diluted 
earnings per share with basic and diluted earnings per share. Unlike primary 
earnings per share, basic earnings per share excludes the dilutive effects of 
options, warrants and convertible securities. Diluted earnings per share is 
very similar to the previously reported fully diluted earnings per share. All 
net income (loss) per common share amounts for all periods have been 
presented, and where appropriate, restated to conform to FAS 128 requirements.
In restating net income (loss) per common share to comply with the requirements
of FAS 128, the Company applied the recently issued Staff Accounting Bulletin
No. 98 ("SAB 98"). As a result of applying the provisions of SAB 98,
the Company has restated the 1995 and 1996 loss per share to exclude the
antidilutive effect of options and warrants granted within one year of
the Company's 1996 initial public offering.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS:

     In June 1997, the FASB issued Statement of Financial Accounting 
Standards No. 130, "Reporting Comprehensive Income" ("FAS 130"). FAS 130 
establishes standards for reporting and display of comprehensive income and 
its components in financial statements and is effective for fiscal years 
beginning after December 15, 1997. The adoption of FAS 130 will have no 
impact on the Company's financial position, results of operations, or cash 
flows.

     In June 1997, the FASB issued Statement of Financial Accounting 
Standards No. 131, "Disclosure about Segments of an Enterprise and Related 
Information" ("FAS 131"). FAS 131 establishes standards for the way that 
public business enterprises report information about operating segments in 
annual financial statements and requires that those enterprises report 
selected information about operating segments in interim financial reports 
issued to stockholders. It also establishes standards for related disclosure 
about products and services, geographic areas and major customers. FAS 131 is 
effective for financial statements for fiscal years beginning after December 
15, 1997. The Company is evaluating the disclosure requirements of FAS 131 
and has not determined whether its adoption will have a material impact on 
its future disclosure requirements.

NOTE 3--INITIAL PUBLIC OFFERING

     On August 28 and August 30, 1996 the Company successfully completed an 
initial public offering of 3,450,000 shares of common stock at $9 per 
share. The Company received total proceeds from the offering, net of 
offering costs, of approximately $27,621,000.

     At December 31,1997, the Company had net operating loss carryforwards for 
federal income tax purposes of approximately $36,000,000, which expire 
beginning in 2004. Based on the Internal Revenue Code of 1986, as amended, 
and changes in the ownership of the Company, utilization of the net operating 
loss carryforwards are subject to annual limitations, which could 
significantly restrict or partially eliminate the utilization of the net 
operating losses. Additionally, the Company has an alternative minimum tax 
credit carryforward of $60,000 available indefinitely.

     Significant components of the Company's income tax expense for the year 
ended December 31, 1997 are as follows:

     In 1997, the Company paid income tax of $58,300. No income taxes were 
paid in 1996 and 1995. Additionally, the Company did not recognize any income 
tax benefit for 1996 and 1995 due to the Company's recurring operating losses 
and valuation allowances established for net deferred tax assets.

NOTE 5--ACQUISITIONS AND DIVESTITURES

     In November 1997, the Company purchased the customer list and certain 
other assets of Cal-Va, Inc. ("Cal-Va"), which operated a regulated medical 
waste business in northern Virginia and Washington D.C. The purchase price 
was paid by the issuance of shares of the Company's common stock and the 
assumption of certain of Cal-Va's liabilities. The purchase price is to be 
adjusted in the event that revenues fall below certain levels.

     In November 1997, the Company purchased selected customer contracts of 
Phoenix Services Inc. ("Phoenix"), which operated a regulated medical waste 
business in the Baltimore, Maryland metropolitan area. The purchase price was 
paid in cash (in January 1998) and by delivery of a $20,000 note due in 
September 1998.

     In August 1997, the Company purchased the customer list and certain 
other assets of Envirotech Enterprises, Inc. which operated a regulated 
medical waste business in Arizona. The purchase price was paid in cash and by 
delivery of a $300,000 note due in August 1998.  The purchase price is to be 
adjusted in the event that acquired revenues fall below certain levels.

   In June 1997, the Company purchased the customer list and certain other 
assets of the regulated medical waste business of Waste Management, Inc. 
("WMI") in Wisconsin ("WMI-WI"). In July 1997, the Company announced the 
purchase of the customer lists and certain other assets of the regulated 
medical waste businesses of Regional Carting, Inc. and Rumpke Container 
Service, Inc. in New Jersey and Ohio, respectively. The purchase price for 
these three acquisitions was paid by  a combination of cash, assumption of 
liabilities and issuance of shares of common stock of the Company and, in one 
case, delivery of a

note which was paid in December 1997. In the event that acquired revenues for 
each of these three companies fall below certain levels, the purchase price 
will be adjusted accordingly.

     In May 1997, the Company announced the acquisition of all of the 
outstanding stock of Environmental Control Co., Inc. ("ECCO"), one of the 
leading medical waste companies in the New York City market. The Company paid 
$4,200,000 in cash; issued 125,000 shares of stock, assumed debt on vehicles 
and issued a $2,300,000 10-year promissory note for the balance of the 
purchase price. The note bears interest at a rate of 6.86% per annum payable 
in 10 equal annual installments of $230,000 starting in May, 1998. The ECCO 
purchase price is subject to downward adjustments to reflect uncollectible 
acquired accounts receivable, additional outstanding obligations not 
reflected in the purchase price at closing, and the extent to which ECCO's 
revenues during the one-year period following closing are less than a 
specified amount.

     In December 1996, the Company purchased the customer lists, vehicles and 
certain other assets of the major portion of WMI's medical waste business 
(the "WMI Acquisition") for $5,450,000 cash and a note for $5,210,000. During 
the quarter ended June 30, 1997, adjustments were made to the value of the 
vehicles purchased and to the purchase price. The purchase price was 
decreased by $756,000 as specified in the agreement, and the related goodwill 
and note payable were adjusted accordingly. The Company finalized its 
estimate of the value of the vehicles purchased and reduced the related note 
accordingly. In the quarter ended December 31, 1997, the purchase price was 
decreased by $163,000 as specified in the agreement, and the related goodwill 
was adjusted accordingly. The Company paid $1,796,650 of the adjusted 
$3,593,301 balance of the note to WMI in December 1997. The balance plus 
accrued interest is due in December 1998.

     In May 1996, the Company purchased the customer list and certain other 
assets of Doctors Environmental Control, Inc. for $400,000 in cash and notes 
payable issued for $600,000, which are payable on May 1, 1998 with an 
interest rate of 6% per annum. In addition, the Company assumed vehicle 
leases totaling $77,000, which were paid off in May 1996, and delivered 
option agreements to shareholders of the seller giving them an option to 
purchase up to a total of 53,816 shares of the Company's common stock. The 
price for the purchase of the common stock upon exercise of each option was 
the surrender and cancellation of the note payable. The options were 
exercised in August 1996.

     In April 1996, the Company purchased the customer list and certain other 
assets of Sharps Incinerator of Fort, Inc. for $757,000 in cash of which 
$562,000 was payable at closing and the balance plus interest was paid  in 
November 1996.

other assets of WMI Medical Services of New England, Inc. for $100,000 in 
cash and $492,000 in notes payable issued to the seller. The notes bear 
interest at a rate of 7.5% per annum with $150,000 plus interest paid in 
1996, $157,000 plus interest paid in 1997 and $185,000 plus interest paid in 
January 1998.

     In July 1995, the Company sold selected customer lists and related 
assets for $248,000. The Company recognized a gain of $50,000 on this

NOTE 5--ACQUISITIONS AND DIVESTITURES (CONTINUED)

     In June 1995 the Company purchased the customer list and transportation 
equipment and assumed certain contract obligations of Safetech Health Care 
for $160,000.

     In April 1995, the Company sold the St. Louis portion of its business to 
a competitor. The Company received $544,000 as payment for the customer list 
and concurrently agreed to resolve an anti-trust lawsuit brought against this 
competitor by the Company. The Company recognized a gain on this transaction 
of$408,000, which is included in selling, general and administrative expense 
in the 1995 Consolidated Statement of Operations.

     For financial reporting purposes these acquisition transactions were 
accounted for using the purchase method of accounting. The total purchase 
price for 1995, 1996 and 1997 of $459,000, $13,013,000 and $10,197,000, 
respectively, net of cash acquired, was allocated to assets acquired and 
liabilities assumed based on the estimated fair market value at the date of 
acquisition. The total purchase price for 1997 acquisitions includes the 
value of 403,000 shares of common stock issued to the sellers. The excess of 
the purchase price over the fair market value of the net assets acquired is 
reflected in the accompanying Consolidated Balance Sheets as goodwill. The 
results of operations of these acquired businesses are included in the 
Consolidated Statement of Operations from the date of the acquisition. The 
effect of these acquisitions would not have a significant effect on the 
Company's operations, except for the WMI Acquisition and the ECCO acquisition.

     The following unaudited pro forma results of the operations assumes that 
the WMI Acquisition occurred as of January 1, 1995 and that the ECCO 
acquisition occurred as of January 1, 1996, after giving effect to certain 
adjustments including amortization of goodwill, increased interest expense on 
debt incurred in connection with the acquisitions and adjustments to record 
incremental recurring costs associated with the consolidation of the 
operations as the historical results of operations of WMI and ECCO did not 
reflect these costs:

     In March 1998, the Company entered into a new revolving line of credit 
with Silicon Valley Bank. To secure this line of credit, the Company granted 
the bank a lien on all of the Company's assets. Borrowings under the line of 
credit are limited to the lesser of $7,500,000 or a specific percentage of 
the Company's eligible receivables, as defined in the loan and security 
agreement. Outstanding borrowings bear interest at the bank's prime rate plus 
0.50% or LIBOR plus 3.0%, at the Company's option. This agreement has a 
maturity date of March 5, 1999. Under the terms of the loan and security 
agreement, the Company is among other things, restricted from paying 
dividends and is required to maintain minimum levels of total liabilities to 
net worth, quick ratio and profitability. The Company had no borrowings under 
its prior $2,500,000 line of credit with the bank as of December 31, 1997.

     In connection with the Company's May 1997 purchase of ECCO's stock, a 
10-year note  for $2,300,000 was issued to the owners of ECCO. The note is 
payable in 10 equal annual installments due on May 1 of each year starting in 
1998. The note bears interest at the rate of 6.86% per annum.

     In connection with the Company's December 1996 purchase of WMI's medical 
waste business, a note payable totaling $5,210,000 was issued to WMI. The 
note was adjusted to $3,593,301, of which $1,796,650 was repaid in 1997 and 
$1,796,651 is due on December 20, 1998. The note bears interest at a rate of 
7% per annum.

In 1995, an agreement was reached with the Rhode Island Department of 
Environmental Management regarding two notices of violation issued in 1994 
and 1995. Although the Company believed that the allegations were meritless, 
the agreement was entered into in order to resolve the matter in the best 
interest of the Company and its customers in a timely manner. The Company 
agreed to pay $35,000 each year from 1995 to 1998, $50,000 in 1999, $60,000 
in 2000 and $150,000 in 2001 to the Rhode Island Air and Water Protection 
Fund. In addition, the Company agreed to perform community services and 
conduct seminars over a five-year period. The Company recorded this 
obligation based on the discounted cash flows expected to be paid over the 
term of agreement, using a discount rate of 11.75%. The recorded obligation 
of $222,000 at December 31, 1997 has been included in mortgage payable and 
other long-term debt. An expense of $458,000 is included in the 1995 
Consolidated Statement of Operations as a selling, general and administrative

expense. This amount reflects the recorded obligation and legal fees incurred 
in the settlement.

     In 1994, a non-interest bearing note in the amount of $2,480,000 was 
issued as part of the purchase of the net assets of Safe Way Disposal 
Systems, Inc. As a result of the Company's initial public offering in August 
1996, a portion of the note was converted into 98,001 shares of common stock 
and the remainder was paid in cash.

     During 1992, the Company entered into an obligation to finance the 
development of its Woonsocket, Rhode Island facility. The development and 
purchase of substantially all of the property and equipment for the 
Woonsocket, Rhode Island facility was financed from the issuance of 
industrial development revenue bonds. The bonds are due in various amounts 
through 2017 at fixed interest rates ranging from 6.0% to 7.375% and are 
collateralized by the property and equipment at the Woonsocket, Rhode Island 
facility. The terms of an agreement entered into in connection with the 
issuance of the bonds contain, among other provisions, requirements for 
maintaining defined levels of working capital and various financial ratios 
including debt to net worth.

     Payments due on long-term debt, excluding capital lease obligations, 
during each of the five years subsequent to December 31, 1997 are as follows:

CAPITAL LEASES:

     In February 1994, the Company entered into a sale leaseback transaction 
for equipment acquisitions at its Yorkville, Wisconsin facility in the amount 
of $882,000. The lease arrangement has a term of 60 months and at the end of 
the lease, the Company will have the option to renew the lease, return the 
equipment or purchase the equipment at a fair market value not to exceed 11% 
of the original purchase price. In January 1996, the Company entered into a 
capital lease obligation of $364,000 for equipment. The lease expires in 
1998.

NOTE 8--COMMON AND PREFERRED STOCK

     In August 1995, the Board of Directors adopted a plan of 
recapitalization which was approved by the Company's stockholders in 
September 1995, pursuant to which the Company reclassified its outstanding 
convertible redeemable preferred stock as common stock. As part of the plan 
of recapitalization, all conversion, redemption and liquidation rights 
associated with the convertible redeemable preferred stock were terminated in 
exchange for the issuance of shares of common stock.

     Shares of the Company's common stock have been reserved for issuance 
upon the exercise of options and warrants. Also see Note 10. These shares 
have been reserved as follows at December 31, 1997:

     For additional information regarding outstanding employee stock options 
and outstanding warrants, see Note 10.

     Options and warrants to purchase 1,170,626 and 838,849 shares of common 
stock were outstanding during 1995 and 1996, respectively, at exercise prices 
ranging from $.53-$69.02 and $.53-$69.02, respectively, but were not included 
in the computation of diluted earnings per common share in these years 
because the Company had net losses  in 1995 and 1996 and the effect would be 
antidilutive.

STOCK OPTIONS:

     In September 1993, the Company's shareholders approved an amended and 
restated stock option plan (the "1993 Plan"), which provided for the granting 
of options to purchase up to 113,018 shares of common stock. In November 
1995, the outstanding options of all current employees were canceled in 
conjunction with the Company's recapitalization.

     In 1995, the Company's Board of Directors and shareholders approved an 
incentive compensation plan (the "1995 Plan"), which as amended and restated 
in 1996, provides for the granting of 1,500,000 shares of common stock in the 
form of stock options and restricted stock to employees, officers, directors 
and consultants of the Company. The exercise price of options granted under 
the 1995 Plan must be at least equal

to the fair market value of the common stock on the date of grant. In 1995, the
Board of Directors authorized the grant to officers and employees of options to
purchase 923,292 shares of the Company's common stock at an exercise price of
$.53 per share. In 1996, the Board of Directors authorized the grant to officers
and employees of options to purchase 229,883 shares of the Company's common
stock at exercise prices ranging from $.53 to $2.12 per share.  No options were
granted under the 1995 Plan during 1996 and 1997. All options granted to date
have 10-year terms and vest over periods of up to four  years after the date of
grant.

     In 1997, the Company's Board of Directors and shareholders approved the 
1997 Stock Option Plan (the "1997 Plan"), which provides for the granting of 
1,500,000 shares of common stock in the form of stock options to selected 
officers, directors and employees of the Company and its subsidiaries.  The 
exercise price of options granted under the 1997 Plan must be at least equal 
to the fair market value of the common stock on the date of grant.  In 1997, 
the Board of Directors authorized the grant to officers and employees of 
options to purchase 376,367 shares of the Company's common stock at exercise 
prices ranging from $7.25 to $9.50 per share. All options granted to date 
have 10-year terms and vest over periods of up to 5 years after the date of 
grant.

   In June 1996, the Company's Board of Directors adopted and in July, 1996, 
the Company's stockholders approved, the Directors Stock Option Plan. The 
plan authorizes stock options for a total of 285,000 shares of common stock 
to be granted to eligible directors of the Company, consisting of directors 
who are neither officers nor employees of the Company. Each of the six 
incumbent eligible directors automatically received an option as of the date 
of closing of the Company's initial public offering for 8,195 shares of 
common stock with an exercise price of $10.25. As of each annual meeting of 
the Company's stockholders, each incumbent eligible director who is 
re-elected as a director at the annual meeting automatically receives an 
option grant based on a predetermined formula. The exercise price of each 
option will be the closing price on the date of grant.  In 1997, each of the 
six incumbent eligible directors automatically received an option as of the 
date of the 1997 annual meeting for 9,500 shares of common stock with an 
exercise price of $7.50. The term of each option is six years from the date 
of grant, and each option vests in 16 equal quarterly installments and may be 
exercised only when it is vested and only while the holder of the option 
remains a director of the Company or during the 90-day period following the 
date that he or she ceases to serve as a director.

     The Company has elected to follow Accounting Principles Board Opinion 
No. 25, "Accounting for Stock Issued to Employees" ("APB 25") and related 
interpretations in accounting for its employee stock options because, as 
discussed below, the alternative fair value accounting provided for under 
Statement of Financial Accounting Standards No. 123, "Accounting for 
Stock-Based Compensation" ("FAS 123"), requires use of option valuation 
models that were not developed for use in valuing employee stock options. 
Under APB 25, because the exercise price of the Company's employee stock 
options approximates the market price of the underlying stock on the date of 
grant, no compensation expense is recognized.

NOTE 10--STOCK OPTIONS AND WARRANTS (CONTINUED)

     Pro forma information regarding net income loss and net loss per share 
is required by FAS 123 as if the Company has accounted for its employee stock 
options granted subsequent to December 31, 1994 under the fair value method 
of that statement.  Options granted in 1997 were valued using the 
Black-Scholes option pricing model. Options granted in 1996 and 1995, as a 
non-public company, were valued using the minimum value method. The following 
assumptions were used in 1995, 1996, and 1997: risk-free interest rates 
ranging from 5.5% to 5.7% in 1995 and 5.1% to 6.7% in 1996 and 5.9% to 6.8% 
in 1997; a dividend yield of 0%; and a weighted-average expected life of the 
option of 31 months in 1995 and 1996 and 72 months in 1997. The 
weighted-average fair values of options granted during 1995, 1996, and 1997 
were $.09 per share, $.79 per share, and $4.48 per share, respectively.

     Option value models require the input of highly subjective assumptions. 
Because the Company's employee stock options have characteristics 
significantly different from those of traded options, and because changes in 
the subjective input assumptions can materially affect the fair value 
estimate, in management's opinion, the existing method does not necessarily 
provide a reliable single measure of the fair value of its employee stock 
options.

     For purposes of pro forma disclosures, the estimated fair value of the 
options is amortized to expense over the option vesting period. The Company's 
pro forma information follows (in thousands, except for per share 
information):

the pro forma effect in future years as the pro forma disclosures reflect 
only the fair value of stock options granted subsequent to December 31, 1994.

WARRANTS:

     The Company, in conjunction with a lease financing agreement, issued the 
lessor warrants to purchase up to 15,064 shares of common stock at $18.58 per 
share. At December 31, 1997, all of these warrants were outstanding.  They 
expire in March 1998.

     The Company, in connection with the issuance of preferred stock, which 
was subsequently reclassified as common stock issued warrants to purchase up 
to 6,773 shares of common stock at an exercise price of $69.02 per share. At 
December 31, 1997, all of these warrants were outstanding. They expire in 
march 1999.

     During 1995, several of the Company's shareholders and directors 
provided a bridge loan to the Company. The loan totaled $830,000 with 
interest at the prime rate plus 3% and was repaid. In addition to the 
interest, the lenders received warrants to purchase 220,559 shares of common 
stock at $1.59 per share. These warrants expire on July 31, 2000. In 1996, 
the lenders exercised warrants to purchase 166,749 shares. At December 31, 
1997, warrants to purchase 53,810 shares of common stock remained outstanding.

NOTE 11--EMPLOYEE STOCK PURCHASE PLAN

     Under a plan for 1997 approved by the Board of Directors, employees of 
Stericycle can purchase shares of common stock at a market price. Under the 
terms of the plan, employees were allowed to purchase shares throughout the 
year and pay for the stock through salary deduction. Employees elected to 
purchase a total of 5,235 shares under this plan during 1997.

NOTE 12--REGISTRATION AGREEMENT

     The Company is a party to a registration agreement which gives certain 
shareholders of the Company registration rights for their shares. The parties 
to the registration agreement are the original holders of the Company's prior 
Class A, B, C, D, E, F, H and I preferred stock and a holder of a warrant to 
purchase up to 15,064 shares of common stock which the Company issued in 
conjunction with a lease financing agreement. After the Company's 1995 
recapitalization, the registration agreement was amended to provide that the 
registration rights applied to the shares of common stock that the parties to 
the registration agreement received pursuant to the recapitalization, shares 
issuable under certain warrants issued to purchasers of the Company's prior 
Class F preferred stock, shares issuable under the warrant issued in 
conjunction with the lease financing agreement and the common stock to be 
delivered by the Company in payment of a note delivered in connection with 
the Safe Way acquisition, for a total of 5,227,608 shares. According to the 
registration agreement (i) at any time, the holders of a majority of the 
shares which are subject to the registration rights can request registration 
of their shares on Form S-1 (a "Long-Form Registration") and the holders of 
at least 25% of these shares can request registration of their shares on Form 
S-2 or S-3, (ii) at any time, one shareholder who is a party to the 
registration agreement may request a Long Form registration, (iii) at any 
time, another shareholder who is a party to the registration agreement can 
request a Long Form registration, and (iv) the parties to the registration 
agreement have the right to include their shares in any registration which is 
requested or in any other registration that the Company may otherwise 
undertake. If any registration is requested, the Company will use its best 
efforts to effect the requested registration at its own expense.

NOTE 13--EMPLOYEE BENEFIT PLAN

     The Company has a 401(k) defined contribution retirement savings plan 
covering substantially all employees of the Company. Each participant may 
elect to defer a portion of his or her compensation subject to certain 
limitations. The Company may match up to 30% of the first $1,000 contributed 
to the plan by each employee. The Company's contributions for the years ended 
December 31, 1995, 1996 and 1997 were approximately $14,000, $14,000 and 
$25,000, respectively.

NOTE 14--RELATED PARTIES

     In February 1997, the Company announced the formation of an 
international joint venture company called Medam S.A. de C.V., ("Medam") 
which will utilize Stericycle's proprietary Electro-Thermal Deactivation 
(ETD) technology to treat medical and infectious waste in the Mexico City 
market. Stericycle's partners in the joint venture are Controladora Ambiental 
S.A. de C.V. ("Contam"), headquartered in Mexico City and Pennoni Associates, 
Inc., headquartered in Philadelphia, Pennsylvania. The Company owns 24.5% of 
the common stock of Medam. During 1997, the Company received partial payments 
for machinery to be delivered to Medam in 1998. At the year ended December 
31, 1997 the Company has

made $461,000 in capital contributions. Capital contributions will be 
approximately $702,000 in 1998.

     In October 1993, the Company entered into an alliance agreement (the 
"Alliance") with an investor in the Company. The purpose of the Alliance was 
to develop new technologies and procedures for recycling regulated medical 
waste. The Company devoted resources to the Alliance research and development 
program during the first 18 months of the Alliance. The investor has rights 
with respect to the development of any Alliance technology as part of the 
research and development program. During the initial 18 months of the

     8.1  EXERCISE PRICE.   The Plan Administrator shall determine the 
exercise price of each Option. The exercise price per share may not be less

last trading day preceding the Grant Date if it is not a trading day).

Option shall be exercisable in full at one time or in installments at 
different times and (ii) the time or times at which the Option or 
Installments shall become and remain exercisable. No Option or Installment

at any time.

     8.3  TERMINATION OF EMPLOYMENT.   Any Option or Installment held by an 
Employee or Officer-Employee which is unexercisable as of his or her 
Termination Date shall expire on the Termination Date. Any Option or 
Installment held by an Employee or Officer-Employee which is exercisable as

unless the expiration date is extended by the Plan Administrator. The Plan 
Administrator may extend the expiration of an exercisable NSO (or an 
exercisable Installment of a NSO) to any date ending on or before the 
applicable Expiration Date. The Plan Administrator may extend the expiration 
of an exercisable ISO (or exercisable Installment of an ISO) to the earlier 
of (i) a date no later than 90 days after the Termination Date or (ii) the 
applicable Expiration Date, unless the termination of the Employee or 
Officer-Employee occurred as a result of his or her death. In this case, the 
Plan Administrator may extend the expiration to the earlier of (i) a date no 
later than the first anniversary of the death of the Employee or 
Officer-Employee or (ii) the applicable Expiration Date.

     8.4  TRANSFERABILITY.   No Option or Installment may be transferred, 
assigned or pledged (whether by operation of law or otherwise), except as 
provided by will or the applicable laws of intestacy, and no Option shall be 
subject to execution, attachment or similar process. An Option or Installment 
may be exercised only by the person to whom it was granted except in the case 
of his or her death, when it may be exercised by the person or persons to 
whom it passes by will or inheritance.

     8.5  ISO LIMITATIONS.   Notwithstanding anything to the contrary in 
Paragraphs 8.1 and 8.2:  (i) the exercise price per share of an ISO granted 
to a 10% Stockholder shall not be less than 110% of the Closing Price on the 
Grant Date (or on the last trading day preceding the Grant Date if it is not 
a trading day); (ii) no ISO granted to a 10% Stockholder may have an 
Expiration Date more than five years from the Grant Date; and (iii) the 
aggregate fair market value (determined in respect of each ISO on the basis 
of the Closing Price on the Grant Date, or on the last trading day preceding 
the Grant Date if it was not a trading day) of the Underlying Shares of all 
ISOs which become exercisable by an individual for the first time in any 
calendar year shall not exceed $100,000.

     8.6  OPTION AGREEMENTS.   Each Option shall be evidenced by a written 
agreement (an "Option Agreement"), in a form approved by the Plan 
Administrator, entered into by the Company and the person to whom the Option 
is granted. Each Option Agreement shall contain the terms, conditions, 
restrictions and limitations applicable to the Option and any other 
provisions that the Plan Administrator considers advisable to include.

                             EXERCISE OF OPTIONS

     9.1  MANNER OF EXERCISE.   An exercisable Option or Installment may be 
exercised in full or in part (but only in respect of a whole number of 
Underlying Shares) by (i) written notice to the Plan Administrator (or its 
designee) stating the number of Underlying Shares in respect of which the 
Option or Installment is being exercised and (ii) full payment of the 
exercise price of those shares.

     9.2  PAYMENT OF EXERCISE PRICE.   Payment of the exercise price of an 
Option or Installment shall be made by certified or bank cashier's check or, 
if permitted by the Plan Administrator (either in the applicable Option 
Agreement or at the time of exercise): (i) a personal check; (ii) delivery of 
shares of Common Stock having a fair market value on the date of exercise 
equal to the exercise price; (iii) directing the 

                                      59
<PAGE>

Company to withhold, from the Underlying Shares otherwise issuable upon 
exercise of the Option or Installment, Underlying Shares having a fair market 
value on the date of exercise equal to the exercise price; (iv) surrendering 
exercisable Options or Installments having a fair market value on the date of 
exercise equal to the exercise price (measuring the fair market value of the 
Options or Installments surrendered by the excess of the aggregate fair 
market value on the date of exercise of the Underlying Shares over the 
aggregate exercise price); (v) any combination of the preceding methods of 
payment; or (vi) any other method of payment authorized by the Plan 
Administrator. For purposes of this Paragraph and Paragraph 9.3, "fair market 
value" shall be determined by the Closing Price on the Nasdaq National Market 
on the date in question (or on the last trading day preceding the date in 
question if it is not a trading day).

     9.3  WITHHOLDING.   Each person exercising a NSO or an Installment of a 
NSO shall remit to the Company an amount sufficient to satisfy its federal, 
state and local withholding tax obligation in connection with the exercise. 
Payment shall be made by certified or bank cashier's check or, if permitted 
by the Plan Administrator (either in the applicable Option Agreement or at 
the time of exercise): (i) a personal check; (ii) delivery of shares of 
Common Stock having a fair market value on the date of exercise equal to the 
withholding obligation; (iii) directing the Company to withhold, from the 
Underlying Shares otherwise issuable upon exercise of the Option or 
Installment, Underlying Shares having a fair market value on the date of 
exercise equal to the withholding obligation; (iv) any combination of the 
preceding methods of payment; or (v) by any other method of payment 
authorized by the Plan Administrator.

                                  ARTICLE 10

                            MISCELLANEOUS PROVISIONS

     10.1 CAPITALIZATION ADJUSTMENTS.   The aggregate number of shares of 
Common Stock for which Options may be granted under the Plan, the aggregate 
number of Underlying Shares in respect of each outstanding Option, and the 
exercise price of each outstanding Option may be adjusted by the Board as it 
considers appropriate in the event of changes in the number of outstanding 
shares of Common Stock by reason of stock dividends, stock splits, 
recapitalizations, reorganizations and the like. Adjustments under this 
Paragraph 10.1 shall be made in the Board's discretion, and its decisions 
shall be final and binding.

     10.2 AMENDMENT AND TERMINATION.   The Board may amend, suspend or 
terminate this Plan at any time. The Company's stockholders shall be required 
to approve any amendment which would materially increase the number of shares 
of Common Stock for which NSOs may be granted or which would increase the 
number of shares of Common Stock for which ISOs may be granted (other than an 
amendment authorized under Paragraph 10.1). If this Plan is terminated, the 
provisions of this Plan shall continue to apply to Options granted prior to 
termination, and no amendment, suspension or termination of the Plan shall 
adversely affect the rights of the holder of any outstanding Option without 
his or her consent.

     10.3 NO RIGHT TO EMPLOYMENT.   Nothing in this Plan or in any Option 
Agreement shall confer on any person the right to continue in the employ of 
the Company or any Subsidiary or limit the right of the Company or Subsidiary 
to terminate his or her employment.

     10.4 NOTICES.   Notices required or permitted under this Plan shall be 
considered to have been duly given if sent by certified or registered mail 
addressed to the Plan Administrator at the Company's principal office or to 
any other person at his or her address as it appears on the Company's payroll 
or other records.

     10.5 SEVERABILITY.   If any provision of this Plan is held illegal or 
invalid for any reason, the illegality or invalidity shall not affect the 
remaining provisions, and the Plan shall be construed and administered as if 
the illegal or invalid provision had not been included.

     10.6 GOVERNING LAW.   This Plan and all Option Agreements shall be 
governed in accordance with the laws of the State of Illinois.
