its name to "Micro-Med Industries, Inc." upon completion of the merger).

         Our common stock is quoted on The Nasdaq National Market system under
the symbol "SRCL." On December 13, 2002, the average of the high and low sales
prices of our common stock was $31.375 per share.

         Unless the context indicates otherwise, all references to "we," "our,"
"us," the "Company" or "Stericycle" refer to Stericycle, Inc. and its
subsidiaries. Our principal executive offices are located at 28161 North Keith
Drive, Lake Forest, Illinois 60045. Our telephone number is (847) 367-5910.

                                  RISK FACTORS

         You should carefully consider the risks described below before making
an investment decision. The trading price of our common stock could decline due
to any of these risks, and you could lose all or part of your investment.

                          RISKS RELATED TO OUR INDUSTRY

         WE ARE SUBJECT TO EXTENSIVE GOVERNMENTAL REGULATION WITH WHICH IT IS
FREQUENTLY DIFFICULT, EXPENSIVE AND TIME-CONSUMING TO COMPLY.

         The medical waste management industry is subject to extensive federal,
state and local laws and regulations relating to the collection, transportation,
packaging, labeling, handling, documentation, reporting, treatment and disposal
of regulated medical waste. Our business requires us to obtain many permits,
authorizations, approvals, certificates or other types of governmental
permission from every jurisdiction where we operate.

         We believe that we currently comply in all material respects with all
applicable permitting requirements. State and local regulations change often,
however, and new regulations are frequently adopted. Changes in the applicable
regulations could require us to obtain new permits or to change the way in which
we operate. We might be unable to obtain the new permits that we require, and
the cost of compliance with new or changed regulations could be significant.

         The permits that we require, especially those to build and operate
treatment plants and transfer facilities, are difficult and time-consuming to
obtain. They may also contain conditions or restrictions that limit our ability
to operate efficiently, and they may not be issued as quickly as we need (or at
all). If we cannot obtain the permits that we need when we need them, or if they
contain unfavorable conditions, it could substantially impair our operations and
reduce our revenues.

         THE HANDLING AND TREATMENT OF HAZARDOUS MEDICAL WASTE CARRIES WITH IT
THE RISK OF PERSONAL INJURY TO EMPLOYEES AND OTHERS.

         Our business requires us to handle materials that may be infectious,
poisonous, corrosive or dangerous to life and property in other ways. While we
strive to handle such materials with care and in accordance with accepted and
safe methods, the possibility of accidents, leaks, spills, and acts of God
always exists. Examples of how people and property may be exposed to such
materials include:

         -      truck accidents;
         -      damaged or leaking containers;
         -      improper storage of medical waste by customers;
         -      vandalism, arson or sabotage;
         -      placement by customers of materials into the waste stream that
                we are not authorized or able to process, such as nuclear waste
                and certain body parts and



- 4 -




                tissues; or
         -      malfunctioning treatment plant equipment.

         Human beings, animals or property might be injured, sickened or damaged
by exposure to medical waste. This in turn could result in lawsuits in which we
are found liable for such injuries, and substantial damages could be awarded
against us.

         While we carry liability insurance intended to cover these
contingencies, particular instances, claims, damages or events may occur that
are not insured against or are inadequately insured against. An uninsured or
underinsured loss could be substantial and could impair our profitability and
reduce our liquidity.

         THE HANDLING OF MEDICAL WASTE EXPOSES US TO THE RISK OF ENVIRONMENTAL
LIABILITIES WHICH MAY NOT BE COVERED BY INSURANCE.

         As a company engaged in medical waste management, we face risks of
liability for environmental contamination. The federal Comprehensive
Environmental Response, Compensation and Liability Act of 1980, or CERCLA, and
similar state laws impose strict liability on current or former owners and
operators of facilities that release hazardous substances into the environment
as well as on the businesses that generate those substances and the businesses
that transport them to the facilities. Responsible parties may be liable for
substantial investigation and clean-up costs even if they operated their
businesses properly and complied with applicable federal and state laws and
regulations.

         Liability under CERCLA may be joint and several, which means that if we
were found to be a business with responsibility for a particular CERCLA site, we
could be required to pay the entire cost of the investigation and clean-up even
though we were not the party responsible for the release of the hazardous
substance and even though other companies might also be liable.

         Our pollution liability insurance excludes liabilities under CERCLA.
Thus, if we were to incur liability under CERCLA and if we could not identify
other parties responsible under the law whom we can compel to contribute to our
expenses, the cost to us could be substantial and could impair our profitability
and reduce our liquidity.

         THE LEVEL OF GOVERNMENTAL ENFORCEMENT OF ENVIRONMENTAL REGULATIONS HAS
AN UNCERTAIN EFFECT ON OUR BUSINESS AND COULD REDUCE THE DEMAND FOR OUR
SERVICES.

         We believe that the government's strict enforcement of laws and
regulations relating to medical waste collection and treatment has been good for
our business. These laws and regulations increased the demand for our services.
We also believe that laws and regulations that made it more difficult or
expensive to use technologies that compete with our proprietary electro-thermal
deactivation ("ETD") treatment process, such as incineration, have previously
given us a competitive advantage. This advantage has diminished, however, and is
likely to be further reduced, because we have increased our own use of
autoclaving and incineration, mainly as a result of purchasing companies,
including the Browning-Ferris Industries, Inc., or BFI, medical




                                     - 5 -





waste business, that use these processes. Approximately 88% of our current
capacity to treat regulated medical waste is provided by incineration and
autoclaving, and this percentage is likely to increase in the future as we
acquire other companies which use these treatment technologies.

         A relaxation of standards or other changes in governmental regulation
of medical waste, such as:

         -      encouraging the use of landfills;
         -      removing obstacles to the use of incineration and autoclaving,
                thus allowing the continued use of existing on-site incinerators
                by medical waste generators without having to incur additional
                compliance costs; or
         -      reducing manpower and money used to enforce environmental
                regulations favorable to our operations;

could increase the number of competitors or reduce the need for our services.

         WE MAY BE REQUIRED TO PAY FINES AND PENALTIES FOR VIOLATIONS OF
ENVIRONMENTAL REGULATIONS OR OUR PERMITS.

         From time to time we are subject to governmental proceedings to enforce
regulations relating to the handling and treatment of medical waste. We have had
to pay fines and penalties and to undertake remedial work at our facilities. We
may be subject to similar proceedings in the future. Government enforcement
actions also may be initiated against us based on claims that we are violating
our permits. Such proceedings could distract management attention from our
business operations and any resulting fines or shut-downs could reduce our
profitability.

                          RISKS RELATED TO OUR BUSINESS

         IF WE ARE UNABLE TO ACQUIRE OTHER MEDICAL WASTE BUSINESSES, OUR REVENUE
AND PROFIT GROWTH MAY BE SLOWED.

         Our growth strategy is based in part on our ability to acquire other
medical waste businesses. We do not know whether in the future we will be able
to:

         -      identify suitable businesses to buy;
         -      complete the purchase of those businesses on terms acceptable to
                us;
         -      improve the operations of the businesses that we buy and
                successfully integrate their operations into our own; or
         -      avoid or overcome any concerns expressed by regulators.

         We compete with other potential buyers for the acquisition of other
medical waste companies. This competition may result in fewer opportunities to
purchase companies that are for sale. It may also result in higher purchase
prices for the businesses that we want to purchase.

         In addition, we cannot be certain that we will:



                                     - 6 -




         -      have enough money;
         -      be able to borrow enough money on reasonable terms;
         -      be able to issue stock or debt instruments (like promissory
                notes) as consideration for the purchase;
         -      or be able to raise enough money by issuing stock or through
                other financing methods;

to complete the purchases of the businesses that we want to acquire.

         We also do not know whether our growth strategy will continue to be
effective. Our business is significantly larger than before, and new
acquisitions may not have the desired benefits that we have expected in the
past.

         THE IMPLEMENTATION OF OUR ACQUISITION STRATEGY COULD BE AFFECTED IN
CERTAIN INSTANCES BY THE CONCERNS OF STATE REGULATORS, WHICH COULD RESULT IN OUR
NOT BEING ABLE TO REALIZE THE FULL SYNERGIES OR PROFITABILITY OF PARTICULAR
ACQUISITIONS.

         We may become subject to inquiries and investigations by state
antitrust regulators from time to time in the course of completing acquisitions
of other medical waste businesses. In order to obtain regulatory clearance for a
particular acquisition, we could be required to modify certain operating
practices of the acquired business or to divest ourselves of one or more assets
of the acquired business. Changes in the terms of our acquisitions required by
regulators or agreed to by us in order to settle regulatory investigations could
impede our acquisition strategy or reduce the anticipated synergies or
profitability of our acquisitions. The likelihood and outcome of inquiries and
investigations from state regulators in the course of completing acquisitions
cannot be predicted.

         AGGRESSIVE PRICING BY EXISTING COMPETITORS AND THE ENTRANCE OF NEW
COMPETITORS COULD DRIVE DOWN OUR PROFITS AND SLOW OUR GROWTH.

         The medical waste industry is very competitive. This has required us in
the past to reduce our prices, especially to large account customers, and
competition may require us to reduce our prices in the future. Substantial price
reductions could significantly reduce our earnings. We face important
competition from a large number of small, local competitors. Because it requires
very little money or technical know-how to compete with us in the collection and
transport of medical waste, there are many regional and local companies in the
industry. We face competition from these businesses and that competition may
exist in each location to which we try to expand in the future. Our competitors
could take actions that would hurt our growth strategy, including the support of
regulations that could delay or prevent us from obtaining or keeping permits.
They might also give financial support to citizens' groups that oppose our plans
to locate a treatment or transfer facility at a particular location.

         Other sources of competition include large waste generators, such as
some hospitals, who maintain their own treatment facilities. These and other
yet-unidentified competitors could prevent us from obtaining new customers and
could take existing customers away from us.



                                     - 7 -




         WE REQUIRE A SIGNIFICANT AMOUNT OF CASH TO SERVICE OUR SUBSTANTIAL
INDEBTEDNESS, WHICH REDUCES THE CASH AVAILABLE TO FINANCE OUR INTERNAL GROWTH
AND OUR ACQUISITION OF OTHER MEDICAL WASTE BUSINESSES.

         We have a substantial amount of indebtedness. As of September 30, 2002,
our total long-term indebtedness was $217.5 million, net of current maturities.
We had borrowings of $31.0 million under our revolving credit facility, and we
had the ability to borrow a further $74.0 million under the facility. Our
required debt service payments during 2003, 2004 and 2005 are $1.2 million,
$7.0 million and $25.2 million, respectively.

         Our ability to make payments on our indebtedness, as well as to fund
our operations and future growth, depends upon our ability to generate cash. Our
success in doing so depends upon the results of our operations and upon general
economic, financial, competitive, regulatory and other factors beyond our
control.

         Our indebtedness could:

         -      make us more vulnerable to unfavorable economic conditions;
         -      make it more difficult to pursue the acquisition of other
                medical waste management businesses; and
         -      require us to dedicate or reserve a large portion of our cash
                flow from operations to making payments on our indebtedness,
                which would prevent us from using it for other purposes.

         RESTRICTIONS IN OUR DEBT INSTRUMENTS MAY LIMIT OUR ABILITY TO PAY
DIVIDENDS, INCUR ADDITIONAL DEBT, MAKE ACQUISITIONS AND MAKE OTHER INVESTMENTS.

         Our debt instruments contain covenants that restrict our ability to
make distributions to stockholders or other payments unless we satisfy certain
financial tests and comply with various financial ratios. If we do not do so,
our creditors could declare a default under our debt instruments, and our
indebtedness could be declared immediately due and payable. Our ability to
comply with the provisions of our debt instruments may be affected by changes in
economic or business conditions beyond our control.

         Our debt instruments also contain covenants that limit our ability to
incur additional indebtedness, acquire other businesses and make capital
expenditures, and impose various other restrictions. These covenants could
affect our ability to operate our business and may limit our ability to take
advantage of potential business opportunities as they arise.

         THE LOSS OF OUR SENIOR EXECUTIVES COULD AFFECT OUR ABILITY TO MANAGE
OUR BUSINESS PROFITABLY.

         We depend on a small number of senior executives. Our future success
will depend, among other things, upon our ability to keep these executives and
to hire other highly qualified employees at all levels. We compete with other
potential employers for employees, and we may

not be successful in hiring and keeping the executives and other employees that
we need. We do not have written employment agreements with our President and
Chief Executive Officer or other executive officers, and officers and other key
employees could leave us with little or no prior notice, either individually or
as part of a group. Our loss or inability to hire key employees could impair our
ability to manage our business and direct its growth.

         OUR EXPANSION INTO FOREIGN COUNTRIES EXPOSES US TO UNFAMILIAR
REGULATIONS AND MAY EXPOSE US TO NEW OBSTACLES TO GROWTH.

         We plan to grow both in the United States and in foreign countries. We
have established operations in Canada, Mexico, Argentina, Australia and South
Africa and have entered into ETD equipment sales and licensing agreements in
Brazil and Japan.

         Foreign operations carry special risks. Although our business in
foreign countries has not yet been affected, our business in the countries in
which we currently operate and those in which we may operate in the future could
be limited or disrupted by:

         -      government controls;
         -      import and export license requirements;
         -      political or economic insecurity;
         -      trade restrictions;
         -      changes in tariffs and taxes;
         -      our unfamiliarity with laws, regulations, and customs;
         -      restrictions on repatriating foreign profits back to the United
                States;
         -      difficulties in staffing and managing international operations.

         Foreign governments and agencies often establish permit and regulatory
standards different from those in the United States. If we cannot obtain foreign
regulatory approvals, or if we cannot get them when we expect, our growth and
profitability from international operations could be limited. Fluctuations in
currency exchange rates and increases in duty rates for ETD equipment could have
similar effects.

         THE COMPETITIVE ADVANTAGES OF OUR ETD TREATMENT PROCESS AND OTHER
ASPECTS OF OUR BUSINESS DEPEND ON PATENTS AND PROPRIETARY RIGHTS.

         We hold ten United States patents relating to the ETD treatment process
and other aspects of processing medical waste. We have filed or have been
assigned patent applications in several foreign countries and we have received
patents in Australia, Canada, France, Hong Kong, Hungary, Mexico, Russia, South
Korea and the United Kingdom.

         Pending or future patent applications may not be granted, issued
patents may not provide us with competitive advantages, and our patents may be
challenged by other parties. In addition, other companies may develop similar
processes or avoid our patents. Litigation or administrative proceedings may be
necessary to enforce the patents issued to us or to determine the scope and
validity of others' proprietary rights. Any litigation or administrative
proceeding could result in



                                     - 9 -




substantial cost to us and distraction of our management. A ruling against us in
any litigation or administrative proceeding could expose us to new competition
and depress our earnings.

         Our commercial success also depends on our not infringing patents
issued to other parties. Patents belonging to other parties may require us to
alter our processes, pay licensing fees or cease using any current or future
processes, and as a result, we may be unable to license the technology rights
that we may require at a reasonable cost or at all. If we can not obtain a
license to any infringing technology that we currently use, it could have a
material adverse effect on our business.

         We own registered and unregistered trademarks and service marks. There
can be no assurance that our registered or unregistered trademarks or service
marks will not infringe upon the rights of other parties. The requirement to
change any of our trademarks, service marks or trade names could result in the
loss of any goodwill associated with that trademark, service mark or trade name
and could entail significant expense.

         OUR EARNINGS COULD DECLINE IF WE WRITE-OFF INTANGIBLE ASSETS, SUCH AS
GOODWILL.

         As a result of purchase accounting for our various acquisitions, our
balance sheet at September 30, 2002 contains goodwill, net of accumulated
amortization, of $421.5 million and other intangible assets, net of accumulated
amortization, of $11.4 million. In the first quarter of 2002, we began to apply
new financial accounting rules under which goodwill is no amortized but is
subject to annual impairment tests.

         On an ongoing basis, we evaluate, based upon the fair value of
reporting units, whether facts and circumstances indicate any impairment of the
value of indefinite-lived intangible assets such as goodwill. As circumstances
after an acquisition can change, the value of these intangible assets may not be
realized by us. If we determine that a significant impairment has occurred, we
would be required to write-off the impaired portion of goodwill and other
unamortized intangible assets, which could have a material adverse effect on our
results of operations in the period in which the write-off occurs.

                         RISKS RELATED TO THIS OFFERING

         THE PRICE OF OUR STOCK IS SUBJECT TO WIDE FLUCTUATION.

         The market price of our common stock may be highly volatile. The market
price of our shares may vary widely depending on:

         -      general economic conditions;
         -      news related to Stericycle;
         -      the action of federal economic regulators;
         -      the overall condition of the stock market;
         -      the market's perception of the medical waste industry;



                                     - 10 -





and many other factors. For example, our stock price may be subject to wide
fluctuations in price if we or our competitors announce transactions, disputes,
settlements, government actions, economic losses or gains or other important
events or information.

                                                                           Total            438,063


                              PLAN OF DISTRIBUTION

         We are registering the shares of common stock covered by this
Prospectus for the Selling Shareholders in accordance with our agreement with
them to register their shares. Under our agreement, they will pay the costs of
registering the shares, up to a total of $25,000, and will also pay any sales
commissions in connection with the sale of their shares. We will pay the costs
of registering the shares if and to the extent that the costs exceed $25,000.

         We have been advised by the Selling Shareholders that they may sell
their shares at any time and from time to time in the open market in ordinary
brokerage transactions at market prices prevailing at the time of sale, or in
privately negotiated transactions at market prices at the time of sale, at
prices related to market prices or at negotiated prices, or by a combination of
these methods.

         The Selling Shareholders may sell their shares to or through
broker-dealers, who may



                                     - 12 -




receive compensation in the form of discounts, concessions or commissions from
the Selling Shareholders or the purchasers of the shares for whom the
broker-dealer may act as an agent or to whom they may sell the shares as a
principal, or both. The compensation to a particular broker-dealer may be in
excess of customary conditions.

         The Selling Shareholders and broker-dealers who act in connection with
a sale of the shares may be deemed to be "underwriters" within the meaning of
the Securities Act of 1933, as amended, and any commissions received by these
broker-dealers and profits on resale of the shares as a principal may been
deemed to be underwriting discounts and commissions under the Securities Act.

         The Selling Shareholders have agreed to coordinate their sale of shares
of our common stock in the open market so that the total number of shares sold
by any one or more of them on any day does not exceed 25% of the shares covered
by this Prospectus.

                                  LEGAL MATTERS

         The legality of the shares of common stock covered by this Prospectus
is being passed upon for us by Johnson and Colmar, 300 South Wacker Drive, Suite
1000, Chicago, Illinois 60601, who serve as the Registrant's outside general
counsel. Partners of Johnson and Colmar beneficially own or have voting or
investment power over 3,388 shares of the Registrant's common stock.

             INFORMATION NOT REQUIRED IN THE REGISTRATION STATEMENT

ITEM 14.        OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

         The following table shows the costs and expenses in connection with the
registration of the shares covered by this Registration Statement:


                                                              

SEC registration fees........................................    $     1,280.99
Legal fees and expenses......................................         12,000.00
Accounting fees and expenses.................................          6,000.00
Nasdaq listing fee...........................................          4,380.63
Other expenses...............................................          1,338.38
                                                                 --------------
Total expenses...............................................    $    25,000.00


         All of these costs and expenses are estimated except for the SEC
registration fees. The Selling Shareholders will pay these costs and expenses,
up to a total of $25,000. We will pay the costs and expenses if and to the
extent that the aggregate amount exceeds $25,000.

ITEM 15.        INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 145 of the Delaware General Corporation Law provides generally
that a person sued as a director, officer, employee or agent of a corporation
may be indemnified by the corporation in non-derivative suits for expenses
(including attorneys' fees), judgments, fines, and amounts paid in settlement if
he or she acted in good faith and in a manner that he or she reasonably believed
to be in or not opposed to the corporation's best interests. In the case of
criminal actions and proceedings, the person also must not have had reasonable
cause to believe that his or her conduct was unlawful. Indemnification of
expenses is also authorized in stockholder derivative actions if the person
acted in good faith and in a manner that he or she reasonably believed to be in
or not opposed to the corporation's best interests and if he or she has not been
found liable to the corporation. Even in this latter instance, the court may
determine that, in view of all the circumstances, the person is entitled to
indemnification for such expenses as the court deems proper. A person sued as a
director, officer, employee or agent of a corporation who has been successful in
defense of the action must be indemnified by the corporation against expenses.

         Article Fifth of our bylaws requires us to indemnify our directors,
officers, employees and agents to the maximum extent permitted by Delaware law.
Article Fifth also requires us to advance the litigation expenses of a director
or officer upon receipt of his or her written undertaking to repay all amounts
advanced if it is ultimately determined that he or she is not entitled to
indemnification.

         Section 102(b)(7) of the Delaware General Corporation Law permits a
corporation to include a provision in its certificate of incorporation
eliminating or limiting the personal liability



                                    - II-1 -




of a director to the corporation or its stockholders for monetary damages for a
breach of the director's fiduciary duty of care. The provision may not eliminate
or limit the liability of a director for breaching his or her duty of loyalty,
failing to act in good faith, engaging in intentional misconduct or knowingly
violating a law, declaring an illegal dividend or approving an illegal stock
repurchase, or obtaining an improper personal benefit.

         Article Ninth of our amended and restated certificate of incorporation
eliminates the personal liability of our directors to the fullest extent
permitted by Section 102(b)(7).

         By reason of directors' and officers' liability insurance that we
maintain, our directors and officers are insured against actual liabilities,
including liabilities under the federal securities laws, for acts or omissions
related to the conduct of their duties.

ITEM 17.        UNDERTAKINGS

Rule 415 Offering

         The Registrant undertakes:

                (1) to file, during any period in which offers or sales are
         being made, a post-


                                    - II-2 -




         effective amendment to this Registration Statement:

                      (i) to include any prospectus required by Section 10(a)(3)
                of the Securities Act of 1933, as amended (the "Securities
                Act");

                      (ii) to reflect in the prospectus any facts or events
                arising after the effective date of this Registration Statement
                (or the most recent post-effective amendment) which,
                individually or in the aggregate, represent a fundamental change
                in the information set forth in this Registration Statement; and

                      (iii) to include any material information with respect to
                the plan of distribution not previously disclosed in this
                Registration Statement or any material change to such
                information in this Registration Statement;

         provided, however, that undertakings (1)(i) and (1)(ii) shall not apply
         if the information required to be included in a post-effective
         amendment by those undertakings is contained in periodic reports filed
         with or furnished to the Commission by the Registrant pursuant to
         Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as
         amended (the "Exchange Act") that are incorporated by reference in this
         Registration Statement;

                (2) that, for the purpose of determining any liability under the
         Securities Act, each such post-effective amendment shall be deemed to
         be a new registration statement relating to the securities offered
         therein, and the offering of such securities at that time shall be
         deemed to be the initial bona fide offering thereof; and

                (3) to remove from registration by means of a post-effective
         amendment any of the securities being registered which remain unsold at
         the termination of the offering; and

Filings Incorporating Subsequent Exchange Act Documents by Reference

         The Registrant undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or Section 15(d) of the Exchange Act which is
incorporated by reference in this Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

Request for Acceleration of Effective Date

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant as described in Item 15, or otherwise, the Registrant has been
advised that in the opinion of the Commission such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by


                                    - II-3 -





such director, officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

the Registrant certifies that it has reasonable grounds to believe that it meets

amendments may make such changes in this Registration Statement (as it may be so
amended) as Mark C. Miller, Richard T. Kogler and Frank J.M. ten Brink, or any
one of them, may deem appropriate, and to do and perform all other related acts
and things necessary to be done.
