[LOGO]             SILICON VALLEY BANK


                   LOAN AND SECURITY AGREEMENT

BORROWER:     STERICYCLE, INC.
ADDRESS: 1419 LAKE COOK ROAD SUITE 410 
         DEERFIELD, ILLINOIS 60015

DATE:    OCTOBER 31, 1995


THIS LOAN AND SECURITY AGREEMENT is entered into on the above date between
SILICON VALLEY BANK COMMERCIAL FINANCE DIVISION ("Silicon"), whose address is
3003 Tasman Drive, Santa Clara, California 95054 and the borrower(s) named above
(jointly and severally, the "Borrower"), whose chief executive office is located
at the above address ("Borrower's Address").  The Schedule to this Agreement
(the "Schedule") shall for all purposes be deemed to be a part of this
Agreement, and the same is an integral part of this Agreement. (Definitions of
certain terms used in this Agreement are set forth in Section 8 below.)

1. LOANS.

    1.1  LOANS.  Silicon will make loans to Borrower(the "Loans"), in amounts
determined by Silicon in its sole discretion, up to the amounts (the "Credit
Limit") shown on the Schedule, provided no Default or Event of Default has
occurred and is continuing.

    1.2  INTEREST.  All Loans and all other monetary Obligations shall bear
interest at the rate shown on the Schedule, except where expressly set forth to
the contrary in this Agreement.  Interest shall be payable monthly, on the last
day of the month.  Interest may, in Silicon's discretion, be charged to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as the other Loans.  Silicon may, in its discretion, charge interest to
Borrower's Deposit Accounts maintained with Silicon.  Regardless of the amount
of Obligations that may be outstanding from time to time, Borrower shall pay
Silicon minimum monthly interest during the term of this Agreement in the amount
set forth on the Schedule (the "Minimum Monthly Interest").

    1.3  OVERADVANCES.  If at any time or for any reason the total of all
outstanding Loans and all other Obligations exceeds the Credit Limit (an
"Overadvance"), Borrower shall immediately pay the amount of the excess to
Silicon, without notice or demand.  Without limiting Borrower's obligation to
repay to Silicon on demand the amount of any Overadvance, Borrower agrees to pay
Silicon interest on the outstanding amount of any Overadvance, on demand, at a
rate equal to the interest rate which would otherwise be applicable to the
Overadvance, plus an additional 2% per annum.

    1.4  FEES.  Borrower shall pay Silicon the fee(s)shown on the Schedule,
which are in addition to all interest and other sums payable to Silicon and are
not refundable.

    1.5  LETTERS OF CREDIT.  At the request of Borrower, Silicon may, in its

the amount shown on the Schedule (the "Letter of Credit Sublimit"), and shall be
reserved against Loans which would otherwise be available hereunder.  Borrower
shall pay all bank charges (including charges of Silicon) for the issuance of
Letters of Credit, together with such additional fee as Silicon's letter of
credit department shall charge in connection with the issuance of the Letters of
Credit.  Any payment by Silicon under or in connection with a Letter of Credit
shall constitute a Loan hereunder on the date such payment is made.  Each Letter
of Credit shall have an expiry date no later than thirty days prior to the
Maturity Date.  Borrower hereby agrees to indemnify, save, and hold Silicon
harmless from any loss, cost, expense, or liability, including payments made by
Silicon, expenses, and reasonable attorneys' fees incurred by Silicon arising
out of or in connection with any Letters of Credit.  Borrower agrees to be bound
by the regulations and interpretations of the issuer of any Letters of Credit

interpretations of any Letter of Credit issued by Silicon for Borrower's
account, and Borrower understands and agrees that Silicon shall not be liable

any error. negligence, or mistake, whether of omission or commission, in
following Borrower's instructions or those contained in the Letters of Credit or
any modifications, amendments, or supplements thereto.  Borrower understands
that Letters of Credit may require Silicon to indemnify the issuing bank for
certain costs or liabilities arising out of claims by Borrower against such
issuing bank.  Borrower hereby agrees to indemnify and hold Silicon harmless
with respect to any loss, cost, expense, or liability incurred by Silicon under
any Letter of Credit as a result of Silicon's indemnification of any such
issuing bank.  The provisions of this Loan Agreement, as it pertains to Letters
of Credit, and any other present or future documents or agreements between
Borrower and Silicon relating to Letters of Credit are cumulative.

"Collateral").

3.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

     In order to induce Silicon to enter into this Agreement and to make Loans,
Borrower represents and warrants to Silicon as follows, and Borrower covenants
that the following representations will continue to be true, and that Borrower
will at all times comply with all of the following covenants:

    3.1  CORPORATE EXISTENCE AND AUTHORITY.  Borrower, if a corporation, is and
will continue to be, duly organized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation.  Borrower is and will
continue to be qualified and licensed to do business in all jurisdictions in
which any failure to do so would have a material adverse effect on Borrower. 
The execution, delivery and performance by Borrower of this Agreement, and all
other documents contemplated hereby (i) have been duly and validly authorized,
(ii) are enforceable against Borrower in accordance with their terms (except as
enforcement may be limited by equitable principles and by bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to creditors'
rights, generally), and (iii) do not violate Borrower's articles or certificate
of incorporation, or Borrower's by-laws, or any law or any material agreement or
instrument which is binding upon Borrower or its property, and (iv) do not
constitute grounds for acceleration of any material indebtedness or obligation
under any material agreement or instrument which is binding upon Borrower or its
property.

    3.2  NAME; TRADE NAMES AND STYLES.  The name of Borrower set forth in the
heading to this Agreement is its correct name.  Listed on the Schedule are all
prior names of Borrower and all of Borrower's present and prior trade names. 
Borrower shall give Silicon 30 days' prior written notice before changing its
name or doing business under any other name.  Borrower has complied, and will in
the future comply, with all laws relating to the conduct of business under a
fictitious business name.

    3.3  PLACE OF BUSINESS; LOCATION OF COLLATERAL. The address set forth in
the heading to this Agreement is Borrower's chief executive office.  In
addition, Borrower has places of business and Collateral is located only at the
locations set forth on the Schedule.  Borrower will give Silicon at least 30
days prior written notice before opening any additional place of business,
changing its chief executive office, or moving any of the Collateral to a
location other than Borrower's Address or one of the locations set forth on the
Schedule.

    3.4  TITLE TO COLLATERAL; PERMITTED LIENS.  Borrower is now, and will at
all times in the future be, the sole owner of all the Collateral, except for
items of Equipment which are leased by Borrower.  The Collateral now is and will
remain free and clear of any and all liens, charges, security interests,
encumbrances and adverse claims, except for Permitted Liens.  Silicon now has,
and will continue to have, a first-priority perfected and enforceable security
interest in all of the Collateral, subject only to the Permitted Liens, and
Borrower will at all times defend Silicon and the Collateral against all claims
of others.  None of the Collateral now is or will be affixed to any real
property in such a manner, or with such intent, as to become a fixture. 
Borrower is not and will not become a lessee under any real property lease
pursuant to which the lessor may obtain any rights in any of the Collateral and
no such lease now prohibits, restrains, impairs or will prohibit, restrain or
impair Borrower's right to remove any Collateral from the leased premises. 
Whenever any Collateral is located upon premises in which any third party has an
interest (whether as owner, mortgagee, beneficiary under a deed of trust, lien
or otherwise), Borrower shall, whenever requested by Silicon, use its best
efforts to cause such third party to execute and deliver to Silicon, in form
acceptable to Silicon, such waivers and subordinations as Silicon shall specify,
so as to ensure that Silicon's rights in the Collateral are, and will continue
to be, superior to the rights of any such third party.  Borrower will keep in
full force and effect, and will comply with all the terms of, any lease of real
property where any of the Collateral now or in the future may be located.

    3.5  MAINTENANCE OF COLLATERAL.  Borrower will maintain the Collateral in
good working condition, and Borrower will not use the Collateral for any
unlawful

purpose.  Borrower will immediately advise Silicon in writing of any material
loss or damage to the Collateral.

Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

    3.7  FINANCIAL CONDITION, STATEMENTS AND REPORTS.  ALL financial statements
now or in the future delivered to Silicon have been, and will be, prepared in
conformity with generally accepted accounting principles and now and in the
future will completely and accurately reflect the financial condition of
Borrower, at the times and for the periods therein stated.  Between the last
date covered by any such statement provided to Silicon and the date hereof,
there has been no material adverse change in the financial condition or business
of Borrower.  Borrower is now and will continue to be solvent.

    3.8  TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS.  Borrower has timely
filed, and will timely file, all tax returns and reports required by foreign,
federal, state and local law, and Borrower has timely paid, and will timely pay,
all foreign, federal, state and local taxes, assessments, deposits and
contributions now or in the future owed by Borrower.  Borrower may, however,
defer payment of any contested taxes, provided that Borrower (i) in good faith
contests Borrower's obligation to pay the taxes by appropriate proceedings
promptly and diligently instituted and conducted, (ii) notifies Silicon in
writing of the commencement of, and any material development in, the
proceedings, and (iii) posts bonds or takes any other steps required to keep the
contested taxes from becoming a lien upon any of the Collateral.  Borrower is
unaware of any claims or adjustments proposed for any of Borrower's prior tax
years which could result in additional taxes becoming due and payable by
Borrower.  Borrower has paid, and shall continue to pay all amounts necessary to
fund all present and future pension, profit sharing and deferred compensation
plans in accordance with their terms, and Borrower has not and will not withdraw
from participation in, permit partial or complete termination of, or permit the
occurrence of any other event with respect to, any such plan which could result
in any liability of Borrower, including any liability to the Pension Benefit
Guaranty Corporation or its successors or any other governmental agency.

relating to Borrower's ownership of real or personal property, the conduct and
licensing of Borrower's business, and all environmental matters.

    3.10 LITIGATION.  Except as disclosed in the Schedule, there is no claim,
suit, litigation, proceeding or investigation pending or (to best of Borrower's
knowledge) threatened by or against or affecting Borrower in any court or before
any governmental agency (or any basis therefor known to Borrower) which may
result, either separately or in the aggregate, in any material adverse change in
the financial condition or business of Borrower, or in any material impairment
in the ability of Borrower to carry on its business in substantially the same
manner as it is now being conducted.  Borrower will promptly inform Silicon in
writing of any claim, proceeding, litigation or investigation in the future
threatened or instituted by or against Borrower involving any single claim of
$50.000 or more, or involving $ 100,000 or more in the aggregate.

    3.11 USE OF PROCEEDS.  All proceeds of all Loans shall be used solely for
lawful business purposes.  Borrower is not purchasing or carrying any "margin
stock" (as defined in Regulation U of the Board of Governors of the Federal
Reserve System) and no part of the proceeds of any Loan will be used to purchase
or carry any "margin stock" or to extend credit to others for the purpose of
purchasing or carrying any "margin stock."

meet the Minimum Eligibility Requirements set forth in Section 8 below.


    4.2  REPRESENTATIONS RELATING TO DOCUMENTS AND LEGAL COMPLIANCE.  Borrower
represents and warrants to Silicon as follows: All statements made and all
unpaid balances appearing in all invoices, instruments and other documents
evidencing the Receivables are and shall be true and correct and all such
invoices, instruments and other documents and all of Borrower's books and
records are and shall be genuine and in all respects what they purport to be,
and all signatories and endorsers have the capacity to contract.  All sales and
other transactions underlying or giving rise to each Receivable shall fully
comply with all applicable laws and governmental rules and regulations.  All
signatures and endorsements on all documents, instruments, and agreements
relating to all Receivables are and shall be genuine, and all such documents,
instruments and agreements are and shall be legally enforceable in accordance
with their terms.

    4.3  SCHEDULES AND DOCUMENTS RELATING TO RECEIVABLES.   Borrower shall
deliver to Silicon transaction reports and loan requests, schedules and
assignments of all Receivables, and schedules of collections, all on Silicon's
standard forms; provided, however, that Borrower's failure to execute and

rights in all of Borrower's Receivables, nor shall Silicon's failure to advance
or lend against a specific Receivable affect or limit

                                         -3-

<PAGE>

    SILICON VA       BANK                        LOAN AND SECURITY AGREEMENT
    ------------------------------------------------------------------------

Silicon's security interest and other rights therein.  Loan requests received
after 2:30 PM will not be considered by Silicon until the next Business Day. 
Together with each such schedule and assignment, or later if requested by
Silicon, Borrower shall furnish Silicon with copies (or, at Silicon's request,
originals) of all contracts, orders, invoices, and other similar documents, and
all original shipping instructions, delivery receipts, bills of lading, and
other evidence of delivery, for any goods the sale or disposition of which gave
rise to such Receivables, and Borrower warrants the genuineness of all of the
foregoing.  Borrower shall also furnish to Silicon an aged accounts receivable
trial balance in such form and at such intervals as Silicon shall request.  In
addition, Borrower shall deliver to Silicon the originals of all instruments,
chattel paper, security agreements, guarantees and other documents and property
evidencing or securing any Receivables, immediately upon receipt thereof and in
the same form as received, with all necessary endorsements, all of which shall
be with recourse.  Borrower shall also provide Silicon with copies of all credit
memos within two days after the date issued.

    4.4  COLLECTION OF RECEIVABLES.  Borrower shall have the right to collect
all Receivables, unless and until a Default or an Event of Default has occurred.
Borrower shall hold all payments on, and proceeds of, Receivables in trust for
Silicon, and Borrower shall immediately deliver all such payments and proceeds
to Silicon in their original form, duly endorsed in blank, to be applied to the
Obligations in such order as Silicon shall determine.  Silicon may, in its
discretion, require that all proceeds of Collateral be deposited by Borrower
into a lockbox account, or such other "blocked account" as Silicon may specify,
pursuant to a blocked account agreement in such form as Silicon may specify. 
Silicon or its designee may, at any time, notify Account Debtors that the
Receivables have been assigned to Silicon.

    4.5. REMITTANCE OF PROCEEDS.  All proceeds arising from the disposition of
any Collateral shall be delivered, in kind, by Borrower to Silicon in the
original form in which received by Borrower not later than the following
Business Day after receipt by Borrower, to be applied to the Obligations in such
order as Silicon shall determine; provided that, if no Default or Event of
Default has occurred, Borrower shall not be obligated to remit to Silicon the
proceeds of the sale of worn out or obsolete equipment disposed of by Borrower
in good faith in an arm's length transaction for an aggregate purchase price of
$25,000 or less (for all such transactions in any fiscal year).  Borrower agrees
that it will not commingle proceeds of Collateral with any of Borrower's other
funds or property, but will hold such proceeds separate and apart from such
other funds and property and in an express trust for Silicon.  Nothing in this
Section limits the restrictions on disposition of Collateral set forth elsewhere
in this Agreement.

    4.6  DISPUTES.  Borrower shall notify Silicon promptly of all disputes or
claims relating to Receivables.  Borrower shall not forgive (completely or
partially), compromise or settle any Receivable for less than payment in
full, or agree to do any of the foregoing, except that Borrower may do so,
provided that: (i) Borrower does so in good faith, in a commercially reasonable
manner, in the ordinary course of business, and in arm's length transactions,
which are reported to Silicon on the regular reports provided to Silicon; (ii)
no Default or Event of Default has occurred and is continuing; and (iii) taking
into account all such discounts settlements and forgiveness, the total
outstanding Loans will not exceed the Credit Limit.  Silicon may, at any time
after the occurrence of an Event of Default, settle or adjust disputes or claims
directly with Account Debtors for amounts and upon terms which Silicon considers
advisable in its reasonable credit judgment and, in all cases, Silicon shall
credit Borrower's Loan account with only the net amounts received by Silicon in
payment of any Receivables.

    4.7  RETURNS.  Provided no Event of Default has occurred and is continuing,
if any Account Debtor returns any Inventory to Borrower in the ordinary course
of its business, Borrower shall promptly determine the reason for such return
and promptly issue a credit memorandum to the Account Debtor in the appropriate
amount (sending a copy to Silicon).  In the event any attempted return occurs
after the occurrence of any Event of Default, Borrower shall, (i) hold the
returned Inventory in trust for Silicon, (ii) segregate all returned Inventory
from all of Borrower's other property, (iii) conspicuously label the returned
Inventory as Silicon's property, and (iv) immediately notify Silicon of the
return of any Inventory, specifying the reason for such return, the location and
condition of the returned Inventory, and on Silicon's request deliver such
returned Inventory to Silicon.

    4.8  VERIFICATION.  Silicon may, from time to time, verify directly with the
respective Account Debtors the validity, amount and other matters relating to
the Receivables, by means of mail, telephone or otherwise, either in the name of
Borrower or Silicon or such other name as Silicon may choose.

    4.9  NO LIABILITY.  Silicon shall not under any circumstances be
responsible or liable for any shortage or discrepancy in, damage to, or loss or
destruction of, any goods, the sale or other disposition of which gives rise to
a Receivable, or for any error, act, omission, or delay of any kind occurring in
the settlement, failure to settle, collection or failure to collect any
Receivable, or for settling any Receivable in good faith for less than the full
amount thereof, nor shall Silicon be deemed to be responsible for any of
Borrower's obligations under any contract or agreement giving rise to a
Receivable.  Nothing herein shall, however, relieve Silicon from liability for
its own gross negligence or willful misconduct.

5.  ADDITIONAL DUTIES OF THE BORROWER.

    5.1  FINANCIAL AND OTHER COVENANTS.  Borrower shall at all times comply
with the financial and other covenants set forth in the Schedule.

                                         -4-

    SILICON VA       BANK                        LOAN AND SECURITY AGREEMENT
    ------------------------------------------------------------------------



    5.2  INSURANCE.  Borrower shall, at all times insure all of the tangible
personal property Collateral and carry such other business insurance, with
insurers reasonably acceptable to Silicon, in such form and amounts as Silicon
may reasonably require, and Borrower shall provide evidence of such insurance to
Silicon, so that Silicon is satisfied that such insurance is, at all times, in
full force and effect.  All such insurance policies shall name Silicon as an
additional loss payee, and shall contain a lenders loss payee endorsement in
form reasonably acceptable to Silicon.  Upon receipt of the proceeds of any such
insurance, Silicon shall apply such proceeds in reduction of the Obligations as
Silicon shall determine in its sole discretion, except that, provided no Default
or Event of Default has occurred and is continuing, Silicon shall release to
Borrower insurance proceeds with respect to Equipment totaling less than
$100,000, which shall be utilized by Borrower for the replacement of the
Equipment with respect to which the insurance proceeds were paid.  Silicon may
require reasonable assurance that the insurance proceeds so released will be so
used.  If Borrower fails to provide or pay for any insurance, Silicon may, but
is not obligated to, obtain the same at Borrower's expense.  Borrower shall
promptly deliver to Silicon copies of all reports made to insurance companies.

    5.3  REPORTS.  Borrower, at its expense, shall provide Silicon with the
written reports set forth in the Schedule, and such other written reports with
respect to Borrower (including budgets, sales promotions, operating plans and
other financial documentation), as Silicon shall from time to time reasonably
specify.

    5.4  ACCESS TO COLLATERAL, BOOKS AND RECORDS.  At reasonable times, and on
one Business Day's notice, Silicon, or its agents, shall have the right to
inspect the Collateral, and the right to audit and copy Borrower's books and
records.  Silicon shall take reasonable steps to keep confidential all
information obtained in any such inspection or audit, but Silicon shall have the
right to disclose any such information to its auditors, regulatory agencies, and
attorneys, and pursuant to any subpoena or other legal process.  The foregoing
inspections and audits shall be at Borrower's expense and the charge therefor
shall be $500 per person per day (or such higher amount as shall represent
Silicon's then current standard charge for the same), plus reasonable out of
pocket expenses.  Borrower will not enter into any agreement with any accounting
firm, service bureau or third party to store Borrower's books or records at any
location other than Borrower's Address, without first obtaining Silicon's
written consent, which may be conditioned upon such accounting firm, service
bureau or other third party agreeing to give Silicon the same rights with
respect to access to books and records and related rights as Silicon has under
this Loan Agreement.  Borrower waives the benefit of any accountant-client
privilege or other evidentiary privilege precluding or limiting the disclosure,
divulgence or delivery of any of its books and records (except that Borrower
does not waive any attorney-client privilege).

    5.5  NEGATIVE COVENANTS.  Except as may be permitted in the Schedule,
Borrower shall not, without Silicon's prior written consent, do any of the
following: (i) merge or consolidate with another corporation or entity; (ii)
acquire any assets, except in the ordinary course of business, (iii) enter into
any other transaction outside the ordinary course of business; (iv) sell or
transfer any Collateral, except for the sale of finished Inventory in the
ordinary course of Borrower's business, and except for the sale of obsolete or

adverse effect on Borrower or on the prospect of repayment of the Obligations;
(ix) guarantee or otherwise become liable with respect to the obligations of
another party or entity; (x) pay or declare any dividends on Borrower's stock
(except for dividends payable solely in stock of Borrower); (xi) redeem, retire,

(xii) make any change in Borrower's capital structure which would have a
material adverse effect on Borrower or on the prospect of repayment of the
Obligations; or (xiii) pay total compensation, including salaries, fees,
bonuses, commissions, and all other payments, whether directly or indirectly, in
money or otherwise, to Borrower's executives, officers and directors (or any
relative thereof) in an amount in excess of the amount set forth on the
Schedule; or (xiv) dissolve or elect to dissolve.  Transactions permitted by the
foregoing provisions of this Section are only permitted if no Default or Event
of Default would occur as a result of such transaction.

    5.6  LITIGATION COOPERATION.  Should any third-party suit or proceeding be
instituted by or against Silicon with respect to any Collateral or in any manner
relating to Borrower, Borrower shall, without expense to Silicon, make available
Borrower and its officers, employees and agents and Borrower's books and
records, to the extent that Silicon may deem them reasonably necessary in order
to prosecute or defend any such suit or proceeding.

    5.7  FURTHER ASSURANCES.  Borrower agrees, at its expense, on request by
Silicon, to execute all documents and take all actions, as Silicon, may deem
reasonably necessary or useful in order to perfect and maintain Silicon's
perfected security interest in the Collateral, and in order to fully consummate
the transactions contemplated by this Agreement.

maturity date set forth on the Schedule (the "Maturity Date"); provided that 
the Maturity date shall automatically be extended, and this Agreement shall 
automatically and continuously renew, for successive additional terms of one 
year each, unless one party gives written notice to the other, not less than 
sixty days prior to

    6.2  EARLY TERMINATION.  This Agreement may be terminated prior to the
Maturity Date as follows: (i) by Borrower, effective three Business Days after
written notice of termination is given to Silicon; or (ii) by Silicon at any
time after the occurrence of an Event of Default, without notice, effective
immediately.  If this Agreement is terminated by Borrower or by Silicon under
this Section 6.2, Borrower shall pay to Silicon the Termination Fee shown on the
Schedule.  The termination fee shall be due and payable on the effective date of
termination and thereafter shall bear interest at a rate equal to the highest
rate applicable to any of the Obligations.

    6.3  PAYMENT OF OBLIGATIONS.  On the Maturity Date or on any earlier
effective date of termination, Borrower shall pay and perform in full all
Obligations, whether evidenced by installment notes or otherwise, and whether or

Without limiting the generality of the foregoing, if on the Maturity Date, or on
any earlier effective date of termination, there are any outstanding Letters of
Credit issued by Silicon or issued by another institution based upon an
application, guarantee, indemnity or similar agreement on the part of Silicon,
then on such date Borrower shall provide to Silicon cash collateral in an amount
equal to the face amount of all such Letters of Credit plus all interest, fees
and cost due or to become due in connection therewith, to secure all of the
Obligations relating to said Letters of Credit, pursuant to Silicon's then
standard form cash pledge agreement.  Notwithstanding any termination of this
Agreement, all of Silicon's security interests in all of the Collateral and all
of the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided that
without limiting the fact that Loans are subject to the discretion of Silicon,
Silicon may, in its sole discretion, refuse to make any further Loans after
termination.  No termination shall in any way affect or impair any right or
remedy of Silicon, nor shall any such termination relieve Borrower of any
Obligation to Silicon, until all of the Obligations have been paid and performed
in full.  Upon payment and performance in full of all the Obligations and
termination of this Agreement, Silicon shall promptly deliver to Borrower
termination statements, requests for reconveyances and such other documents as
may be required to fully terminate Silicon's security interests.

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


property which may be fraudulent under any bankruptcy, fraudulent conveyance or
similar law; or (p) there shall be a material adverse change in Borrower's
business or financial condition or there shall occur any revocation or
termination of any of Borrower's governmental permits, licenses or entitlements
which has, or can reasonably be expected to have, a material adverse effect on
Borrower; or (q) Silicon, acting in good faith and in a commercially reasonable
manner, deems itself insecure because of the occurrence of an event prior to the
effective date hereof of which Silicon had no knowledge on the effective date or
because of the occurrence of an event on or subsequent to the effective date. 
Silicon may cease making any Loans hereunder during any of the above cure
periods, and thereafter if an Event of Default has occurred.

    7.2  REMEDIES.  Upon the occurrence of any Event of Default, and at any
time thereafter, Silicon, at its option, and without notice or demand of any
kind (all of which are hereby expressly waived by Borrower), may do any one or
more of the following: (a) Cease making Loans or otherwise extending credit to
Borrower under this Agreement or any other document or agreement; (b) Accelerate
and declare all or any part of the Obligations to be immediately due, payable,
and performable, notwithstanding any deferred or installment payments allowed by
any instrument evidencing or relating to any Obligation; (c) Take possession of
any or all of the Collateral wherever it may be found, and for that purpose
Borrower hereby authorizes Silicon without judicial process to enter onto any of
Borrower's premises without interference to search for, take possession of,
keep, store, or remove any of the Collateral, and remain on the premises or
cause a custodian to remain on the premises in exclusive control thereof,
without charge for so long as Silicon deems it reasonably necessary in order to
complete the enforcement of its rights under this Agreement or any other
agreement; provided, however, that should Silicon seek to take possession of any
of the Collateral by Court process, Borrower hereby irrevocably waives: (i) any
bond and any surety or security relating thereto required by any statute, court
rule or otherwise as an incident to such possession; (ii) any demand for
possession prior to the commencement of any suit or action to recover possession
thereof; and (iii) any requirement that Silicon retain possession of, and not
dispose of, any such Collateral until after trial or final judgment; (d) Require
Borrower to assemble any or all of the Collateral and make it available to
Silicon at places designated by Silicon which are reasonably convenient to
Silicon and Borrower, and to remove the Collateral to such locations as Silicon
may deem advisable; (e) Complete the processing, manufacturing or repair of any
Collateral prior to a disposition thereof and, for such purpose and for the
purpose of removal, Silicon shall have the right to use Borrower's premises,
vehicles, hoists, lifts, cranes, equipment and all other property without
charge; (f) Sell, lease or otherwise dispose of any of the Collateral, in its
condition at the time Silicon obtains possession of it or after further
manufacturing, processing or repair, at one or more public and/or private sales,
in lots or in bulk, for cash, exchange or other property, or on credit, and to
adjourn any such sale from time to time without notice other than oral
announcement at the time scheduled for sale.  Silicon shall have the right to
conduct such disposition on Borrower's premises without charge, for such time or
times as Silicon deems reasonable, or on Silicon's premises, or elsewhere and
the Collateral need not be located at the place of disposition.  Silicon may
directly or through any affiliated company purchase or lease any Collateral at
any such public disposition, and if permissible under applicable law, at any
private disposition.  Any sale or other disposition of Collateral shall not
relieve Borrower of any liability Borrower may have if any Collateral is
defective as to title or physical condition or otherwise at the time of sale;
(g) Demand payment of, and collect any Receivables and General Intangibles
comprising Collateral and, in connection therewith, Borrower irrevocably
authorizes Silicon to endorse or sign Borrower's name on all collections,
receipts, instruments and other documents, to take possession of and open mail
addressed to Borrower and remove therefrom payments made with respect to any
item of the Collateral or proceeds thereof, and, in Silicon's sole discretion,
to grant extensions of time to pay, compromise claims and settle Receivables and
the like for less than face value; (h) Offset against any sums in any of
Borrower's general, special or other Deposit Accounts with Silicon; and (i)
Demand and receive possession of any of Borrower's federal and state income tax
returns and the books and records utilized in the preparation thereof or
referring thereto.  All reasonable attorneys' fees, expenses, costs, liabilities
and obligations incurred by Silicon with respect to the foregoing shall be added
to and become part of the Obligations, shall be due on demand, and shall bear
interest at a rate equal to the highest interest rate applicable to any of the
Obligations.  Without limiting any of Silicon's rights and remedies, from and
after the occurrence of any Event of Default, the interest rate applicable to
the Obligations shall be increased by an additional four percent per annum.

    7.3  STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS.  Borrower and
Silicon agree that a sale or other disposition (collectively, "sale") of any
Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable: (i) Notice of the sale is given to
Borrower at least seven days prior to the sale, and, in the case of a public
sale, notice of the sale is published at least seven days before the sale in a
newspaper of general circulation in the county where the sale is to be
conducted; (ii) Notice of the sale describes the collateral in general, non-
specific terms; (iii) The sale is conducted at a place designated by Silicon,
with or without the Collateral being present; (iv) The sale commences at any
time between 8:00 a.m. and 6:00 p.m.; (v) Payment of the purchase price in cash
or by cashier's check or wire transfer is required; (vi) With respect to any
sale of any of the Collateral, Silicon may (but is not obligated to) direct any
prospective purchaser to ascertain directly from Borrower any and all
information concerning the same.  Silicon shall be free to employ

                                         -7- 
<PAGE>

other methods of noticing and selling the Collateral, in its discretion, if they
are commercially reasonable.

    7.4  POWER OF ATTORNEY.  Upon the occurrence of any Event of Default,
without limiting Silicon's other rights and remedies, Borrower grants to Silicon
an irrevocable power of attorney coupled with an interest, authorizing and
permitting Silicon (acting through any of its employees, attorneys or agents) at
any time, at its option, but without obligation, with or without notice to
Borrower, and at Borrower's expense, to do any or all of the following, in
Borrower's name or otherwise, but Silicon agrees to exercise the following
powers in a commercially reasonable manner: (a) Execute on behalf of Borrower
any documents that Silicon may, in its sole discretion, deem advisable in order
to perfect and maintain Silicon's security interest in the Collateral, or in
order to exercise a right of Borrower or Silicon, or in order to fully
consummate all the transactions contemplated under this Agreement, and all other
present and future agreements; (b) Execute on behalf of Borrower any document
exercising, transferring or assigning any option to purchase, sell or otherwise
dispose of or to lease (as lessor or lessee) any real or personal property which
is part of Silicon's Collateral or in which Silicon has an interest; (c) Execute
on behalf of Borrower, any invoices relating to any Receivable, any draft
against any Account Debtor and any notice to any Account Debtor, any proof of
claim in bankruptcy, any Notice of Lien, claim of mechanic's, materialman's or
other lien, or assignment or satisfaction of mechanic's, materialman's or other
lien; (d) Take control in any manner of any cash or non-cash items of payment or
proceeds of Collateral; endorse the name of Borrower upon any instruments, or
documents, evidence of payment or Collateral that may come into Silicon's
possession; (e) Endorse all checks and other forms of remittances received by
Silicon; (f) Pay, contest or settle any lien, charge, encumbrance, security
interest and adverse claim in or to any of the Collateral, or any judgment based
thereon, or otherwise take any action to terminate or discharge the same; (g)
Grant extensions of time to pay, compromise claims and settle Receivables and
General Intangibles for less than face value and execute all releases and other
documents in connection therewith; (h) Pay any sums required on account of
Borrower's taxes or to secure the release of any liens therefor, or both; (i)
Settle and adjust, and give releases of, any insurance claim that relates to any
of the Collateral and obtain payment therefor; (j) Instruct any third party
having custody or control of any books or records belonging to, or relating to,
Borrower to give Silicon the same rights of access and other rights with respect
thereto as Silicon has under this Agreement; and (k) Take any action or pay any
sum required of Borrower pursuant to this Agreement and any other present or
future agreements.  Any and all reasonable sums paid and any and all reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by
Silicon with respect to the foregoing shall be added to and become part of the
Obligations, shall be payable on demand, and shall bear interest at a rate equal
to the highest interest rate applicable to any of the Obligations.  In no event
shall Silicon's rights under the foregoing power of attorney or any of Silicon's
other rights under this Agreement be deemed to indicate that Silicon is in
control of the business, management or properties of Borrower.

    7.5  APPLICATION OF PROCEEDS.  All proceeds realized as the result of any
sale of the Collateral shall be applied by Silicon first to the reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by
Silicon in the exercise of its rights under this Agreement, second to the
interest due upon any of the Obligations, and third to the principal of the
Obligations, in such order as Silicon shall determine in its sole discretion. 
Any surplus shall be paid to Borrower or other persons legally entitled thereto;
Borrower shall remain liable to Silicon for any deficiency.  If, Silicon, in its
sole discretion, directly or indirectly enters into a deferred payment or other
credit transaction with any purchaser at any sale of Collateral, Silicon shall
have the option, exercisable at any time, in its sole discretion, of either
reducing the Obligations by the principal amount of purchase price or deferring
the reduction of the Obligations until the actual receipt by Silicon of the cash
therefor.

    7.6  REMEDIES CUMULATIVE. In addition to the rights and remedies set forth
in this Agreement, Silicon shall have all the other rights and remedies accorded
a secured party under the California Uniform Commercial Code and under all other
applicable laws, and under any other instrument or agreement now or in the
future entered into between Silicon and Borrower, and all of such rights and
remedies and cumulative and none is exclusive.  Exercise or partial exercise by
Silicon of one or more of its rights or remedies shall not be deemed an
election, nor bar Silicon from subsequent exercise or partial exercise of any
other rights or remedies.  The failure or delay of Silicon to exercise any
rights or remedies shall not operate as a waiver thereof, but all rights and
remedies shall continue in full force and effect until all of the Obligations
have been fully paid and performed.

    "ACCOUNT DEBTOR" means the obligor on a Receivable.

    "ELIGIBLE RECEIVABLES" means Receivables arising in the ordinary course of
Borrower's business from the sale of goods or rendition of services, which
Silicon, in its sole judgment, shall deem eligible for borrowing, based on such
considerations as Silicon may from time to time deem appropriate.  Without
limiting the fact that the determination of which Receivables are eligible for
borrowing is a matter of Silicon's discretion, the following (the "MINIMUM 
ELIGIBILITY REQUIREMENTS") are the minimum requirements for a Receivable to be
an Eligible Receivable: (i) the Receivable must not be outstanding for more than
90 days from its invoice date, (ii) the Receivable must not represent progress
billings, or be due under a fulfillment or requirements contract with the
Account Debtor, (iii) the Receivable must not be subject to any contingencies
(including Receivables arising from sales on consignment, guaranteed sale or
other terms pursuant to which payment by the Account Debtor may be conditional),
(iv) the Receivable must not be owing from an Account Debtor with whom the
Borrower has any dispute (whether or not relating to the particular Receivable),
(v) the Receivable must not be owing from an Affiliate of Borrower, (vi) the
Receivable must not be owing from an Account Debtor which is subject to any
insolvency or bankruptcy proceeding, or whose financial condition is not
acceptable to Silicon, or which, fails or goes out of a material portion of its
business, (vii) the Receivable must not be owing from the United States or any
department, agency or instrumentality thereof (unless there has been compliance,
to Silicon's satisfaction, with the United States Assignment of Claims Act*),

the United States or Canada (unless pre-approved by Silicon in its discretion in
writing, or backed by a letter of credit satisfactory to Silicon, or FCIA
insured satisfactory to Silicon), (ix) the Receivable must not be owing from an
Account Debtor to whom Borrower is or may be liable for goods purchased from
such Account Debtor or otherwise.  Receivables owing from one Account Debtor
will not be deemed Eligible Receivables to the extent they exceed 25% of the
total eligible Receivables outstanding.  In addition, if more than 50% of the
Receivables owing from an Account Debtor are outstanding more than 90 days from
their invoice date (without regard to unapplied credits) or are otherwise not
eligible Receivables, then all Receivables owing from that Account Debtor will
be deemed ineligible for borrowing.  Silicon may, from time to time, in its
discretion, revise the Minimum Eligibility Requirements, upon written notice to
the Borrower.

security interest is subordinate to the security interest in favor of Silicon,
and agree not to take any action to enforce its subordinate security interest so

9.  GENERAL PROVISIONS.

    9.1  INTEREST COMPUTATION.  In computing interest on the Obligations, all
checks, wire transfers and other items of payment received by Silicon (including
proceeds of Receivables and payment of the Obligations in full) shall be deemed
applied by Silicon on account of the Obligations three Business Days after
receipt by Silicon of immediately available funds, and, for purposes of the
foregoing, any such funds received after 2:30 PM on any day shall be deemed
received on the next Business Day.  Silicon shall not, however, be required to
credit Borrower's account for the amount of any item of payment which is
unsatisfactory to Silicon in its sole discretion, and Silicon may charge
Borrower's loan account for the amount of any item of payment which is returned
to Silicon unpaid.

    9.2  APPLICATION OF PAYMENTS.  All payments with respect to the Obligations
may be applied, and in Silicon's sole discretion reversed and re-applied, to the
Obligations, in such order and manner as Silicon shall determine in its sole
discretion.

    9.3  CHARGES TO ACCOUNTS.  Silicon may, in its discretion, require that
Borrower pay monetary Obligations in cash to Silicon, or charge them to
Borrower's Loan account, in which event they will bear interest at the same rate
applicable to the Loans.  Silicon may also, in its discretion, charge any
monetary Obligations to Borrower's Deposit Accounts maintained with Silicon.

    9.4  MONTHLY ACCOUNTINGS.  Silicon shall provide Borrower monthly with an
account of advances, charges, expenses and payments made pursuant to this
Agreement.  Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications of
payments made and corrections of errors discovered by Silicon), unless Borrower
notifies Silicon in writing to the contrary within thirty days after each
account is rendered, describing the nature of any alleged errors or admissions.

writing and shall be given either personally or by reputable private delivery
service or by regular first-class mail, or certified mail return receipt
requested, addressed to Silicon or Borrower at the addresses shown in the

party to the other party.  Notices to Silicon shall be directed to the
Commercial Finance Division, to the attention of the Division Manager or the
Division Credit Manager.  All

    SILICON VALLEY BANK                          LOAN AND SECURITY AGREEMENT
    ------------------------------------------------------------------------

notices shall be deemed to have been given upon delivery in the case of notices
personally delivered, or at the expiration of one Business Day following
delivery to the private delivery service, or two Business Days following the
deposit thereof in the United States mail, with postage prepaid.

    9.6  SEVERABILITY.  Should any provision of this Agreement be held by any
court of competent jurisdiction to be void or unenforceable, such defect shall
not affect the remainder of this Agreement, which shall continue in full force
and effect.

    9.7  INTEGRATION.  This Agreement and such other written agreements,
documents and instruments as may be executed in connection herewith are the
final, entire and complete agreement between Borrower and Silicon and supersede
all prior and contemporaneous negotiations and oral representations and
agreements, all of which are merged and integrated in this Agreement.  THERE ARE
NO ORAL UNDERSTANDINGS, REPRESENTATIONS OR AGREEMENTS BETWEEN THE PARTIES WHICH
ARE NOT SET FORTH IN THIS AGREEMENT OR IN OTHER WRITTEN AGREEMENTS SIGNED BY THE
PARTIES IN CONNECTION HEREWITH.

    9.8  WAIVERS.  The failure of Silicon at any time or times to require 
Borrower to strictly comply with any of the provisions of this Agreement or 
any other present or future agreement between Borrower and Silicon shall not 
waive or diminish any right of Silicon later to demand and receive strict 
compliance therewith.  Any waiver of any default shall not waive or affect 
any other default, whether prior or subsequent, and whether or not similar.  
None of the provisions of this Agreement or any other agreement now or in the 
future executed by Borrower and delivered to Silicon shall be deemed to have 
been waived by any act or knowledge of Silicon or its agents or employees, 
but only by a specific written waiver signed by an authorized officer of 
Silicon and delivered to Borrower.  Borrower waives demand, protest, notice 
of protest and notice of default or dishonor, notice of payment and 
nonpayment, release, compromise, settlement, extension or renewal of any 
commercial paper, instrument, account, General Intangible, document or 
guaranty at any time held by Silicon on which Borrower is or may in any way 
be liable, and notice of any action taken by Silicon, unless expressly 
required by this Agreement.

    9.9  NO LIABILITY FOR ORDINARY NEGLIGENCE.  Neither Silicon, nor any of its
directors, officers, employees, agents, attorneys or any other Person affiliated
with or representing Silicon shall be liable for any claims, demands, losses or
damages, of any kind whatsoever, made, claimed, incurred or suffered by Borrower
or any other party through the ordinary negligence of Silicon, or any of its
directors, officers, employees, agents, attorneys or any other Person affiliated
with or representing Silicon, but nothing herein shall relieve Silicon from
liability for its own gross negligence or willful misconduct.

    9.10 AMENDMENT.  The terms and provisions of this Agreement may not be
waived or amended, except in a writing executed by Borrower and a duly
authorized officer of Silicon.

    9.11 TIME OF ESSENCE.  Time is of the essence in the performance by
Borrower of each and every obligation under this Agreement.

    9.12 ATTORNEYS FEES AND COSTS.  Borrower shall reimburse Silicon for all
reasonable attorneys' fees and all filing, recording, search, title insurance,
appraisal, audit, and other reasonable costs incurred by Silicon, pursuant to,
or in connection with, or relating to this Agreement (whether or not a lawsuit
is filed), including, but not limited to, any reasonable attorneys' fees and
costs Silicon incurs in order to do the following: prepare and negotiate this
Agreement and the documents relating to this Agreement; obtain legal advice in
connection with this Agreement or Borrower; enforce, or seek to enforce, any of
its rights; prosecute actions against, or defend actions by, Account Debtors:
commence, intervene in, or defend any action or proceeding; initiate any
complaint to be relieved of the automatic stay in bankruptcy; file or prosecute
any probate claim, bankruptcy claim, third-party claim, or other claim; examine,
audit, copy, and inspect any of the Collateral or any of Borrower's books and
records; protect, obtain possession of, lease, dispose of, or otherwise enforce
Silicon's security interest in, the Collateral; and otherwise represent Silicon
in any litigation relating to Borrower.  IN SATISFYING BORROWER'S OBLIGATION
HEREUNDER TO REIMBURSE SILICON FOR ATTORNEYS' FEES,  BORROWER MAY, FOR
CONVENIENCE, ISSUE CHECKS DIRECTLY TO SILICON'S ATTORNEYS, LEVY, SMALL & LALLAS,
BUT BORROWER ACKNOWLEDGES AND AGREES THAT LEVY, SMALL & LALLAS IS REPRESENTING
ONLY SILICON AND NOT BORROWER IN CONNECTION WITH THIS AGREEMENT. If either
Silicon or Borrower files any lawsuit against the other predicated on a breach
of this Agreement, the prevailing party in such action shall be entitled to
recover its reasonable costs and attorneys' fees, including (but not limited to)
reasonable attorneys' fees and costs incurred in the enforcement of, execution
upon or defense of any order, decree, award or judgment.  All attorneys' fees
and costs to which Silicon may be entitled pursuant to this Paragraph shall
immediately become part of Borrower's Obligations, shall be due on demand, and
shall bear interest at a rate equal to the highest interest rate applicable to
any of the Obligations.

    9.13 BENEFIT OF AGREEMENT.  The provisions of this Agreement shall be
binding upon and inure to the benefit of the respective successors, assigns,
heirs, beneficiaries and representatives of Borrower and Silicon; provided,
however, that Borrower may not assign or transfer any of its rights under this
Agreement without the prior written consent of Silicon, and any prohibited
assignment shall be void.  No consent by Silicon to any assignment shall release
Borrower from its liability for the Obligations.

    9.14 JOINT AND SEVERAL LIABILITY.  If Borrower consists of more than one
Person, their liability shall be joint and several, and the compromise of any
claim with, or the release of, any Borrower shall not constitute a compromise
with, or a release of, any other Borrower.

    9.15 LIMITATION OF ACTIONS.  Any claim or cause of action by Borrower
against Silicon, its directors, officers, employees, agents, accountants or
attorneys, based upon, arising from, or relating to this Loan Agreement, or any
other present or future document or agreement, or any other transaction
contemplated hereby or thereby or relating hereto or thereto, or any other
matter, cause or thing whatsoever, occurred, done, omitted or suffered to be

                                  equal to the "Prime Rate" in effect from time

                                  principles, consistently applied.  Interest

                                  charged by Silicon are based, and it is not
                                  necessarily the best rate available at
                                  Silicon.  The interest rate applicable to the

    The Parties agree to amend the Loan and Security Agreement between them,
dated October 31, 1996 (the "Loan Agreement"), as follows, effective on 
March 12, 1996. (Capitalized terms used but not defined in this Amendment,

    1.   CHANGE TO ADVANCE RATE.  Section 1 of the Schedule to the Loan
Agreement (the "Schedule") is hereby amended to read:

         "1. CREDIT LIMIT

         (Section 1.1):      An amount not to exceed the lesser of: (i)
                             $2,500,000 at any one time outstanding; or (ii)
                             70% of the amount of Borrower's Eligible
                             Receivables (as defined in Section 8 above).

         Letter of Credit Sublimit
         (Section 1.5):      $500,000"

    2.   DETERMINATION OF LOAN AVAILABILITY ONCE PER MONTH.  Notwithstanding
any other terms or provisions of the Loan Agreement, unless and until Silicon

loan availability under Section 4 of this Amendment, the following provisions
shall apply:

         (a)  The amount available for Borrower to borrow under the Loan
Agreement shall be determined as follows:

         Upon Silicon's receipt from Borrower of a Receivable aging, pursuant to
    Section 6 of the Schedule, Silicon shall calculate the amount of the
    Credit Limit, pursuant to Section 1 of the Schedule.  Such amount shall
    serve as the Credit Limit until Silicon receives from Borrower, the next
    scheduled Receivable aging.  If on the date Silicon receives a Receivable
    aging from Borrower the amount of outstanding Loans exceeds the Credit
    Limit, so that an Overadvance exists, then without limiting Borrower's
    obligation to repay to Silicon on demand the amount of such Overadvance as
    set forth in Section 1.3

remedies, but each and every such remedy shall be cumulative and shall be in
addition to every other remedy given under this Guaranty to either of them or
now or hereafter existing at law or in equity.

     No delay or omission to exercise any right or power accruing upon any
default, omission or failure of performance hereunder shall impair any such
right or power or shall be construed to be a waiver thereof, but any such right
and power may be exercised from time to time and as often as may be deemed
expedient.  In order to entitle the Trustee and the Authority to exercise any
remedy reserved to it in this Guaranty, it shall not be necessary to give any
notice, other than such notice as may be herein expressly required.

     In the event any provision contained in this Guaranty should be breached by
any party and thereafter duly waived by any other party so empowered to act,

deemed to waive any other breach hereunder.  No waiver, amendment, release or
modification of this Guaranty shall be established by conduct, custom, or course
of dealing, but solely by an instrument in writing duly executed by the parties
thereunto duly authorized by this Guaranty.

any right or remedy of the Authority hereunder.  Any action taken or any

its part.  No waiver, forbearance, extension of time or other indulgence 
shown by the Authority to the Obligor or to any other person now or hereafter 
having any interest in the Project, with respect to any condition, covenant 
or agreement of them or any of them shall affect the right of the Authority 
thereafter to require performance or observance of the same or any other 
condition, covenant or agreement.  The failure of the Authority to act or the 
waiver in any instance of the exercise of any right or remedy of the 
Authority hereunder shall not be deemed to thereafter bar the Authority from 
acting and shall not constitute a waiver of any other right or remedy or 
prevent the subsequent exercise of such right or remedy or any similar right 
or remedy.

    (3)  Obligor acknowledges that a breach of any covenant hereunder shall
constitute a default under this Regulatory Agreement, and Obligor, the Issuer
and the Trustee agree that in the event of such default under this Regulatory
Agreement, the Authority may in its discretion notify them that such default
shall also constitute an Event of Default under the Lease and in such event the
Issuer, the Trustee and the Authority shall be entitled to pursue any remedy
available to them or any of them under the Lease for such breach.

    (4)  The Authority shall not be liable for any of its acts hereunder except
for gross negligence and intentional misconduct.  In no event shall the
Authority be liable for any failure to act.

    (5)  This instrument shall bind, and the benefits shall inure to, the
respective parties hereto, their legal representatives, executors,
administrators, successors in office or interest and assigns and all owners of
the Mortgaged Property, so long as the Insurance Agreements continue in effect
and during such further time as the Authority shall be the owner or insurer of
the Mortgage or obligated to insure the Mortgage.  No modification, amendment or
waiver of any provision hereof shall be effective without the written consent of
the Authority.

    (6)  The invalidity of any clause, part or provision of this Regulatory
Agreement shall not affect the validity of the remaining portions thereof.


                                         -5-

    (8)  Except as required by law, the Authority hereby agrees to maintain the
confidentiality of any information provided by the Obligor with respect to trade

     WHEREAS, Baxter, through its Convertors/Custom Sterile Pharmaseal Surgical
Division (the "Division"), sells and distributes disposable products including
drapes, gowns and custom procedure packs for use in medical and surgical
procedures;

     WHEREAS, Baxter and its customers are concerned about the handling,
management, collection, transportation, treatment and disposal of Infectious

disposal of Infectious Medical Waste in a manner which minimizes the impact on
the environment, and in particular have an interest in recycling as an
alternative to current Infectious Medical Waste disposal practices;

     WHEREAS, the Division intends to offer a product system that allows
customers to choose to have a third party provide for the collection,
transportation, treatment and disposal of Infectious Medical Waste in connection
with such product system;

     WHEREAS, Baxter desires to increase the amount of Baxter Products in the
Waste Stream that are recycled for use in other Baxter Products;

     WHEREAS, Stericycle is engaged in the business of collecting, transporting,
treating and disposing of Infectious Medical Waste and has developed a process
for the treatment of Infectious Medical Waste to eliminate infectious substances

materials;

     WHEREAS, in particular, Stericycle has certain expertise in, and has
developed certain technology with respect to, certain recycling processes with
respect to polypropylene found in the Waste Stream;

     WHEREAS, Stericycle desires to increase the utilization of its facilities;
and

     WHEREAS, contemporaneously with the execution of this Agreement, Baxter has
made an $8,000,000 equity investment in Stericycle and Stericycle has issued
70,000 shares of its Class E Preferred Stock to Baxter (together with any Common
Stock into which such Preferred Stock may be converted, the "Stericycle

respect to the proposal concerning such project within 120 days after it was
first submitted in writing to the Committee), Stericycle may pursue and fund
such project independently and any developments or inventions resulting from
such project shall be Stericycle Technology; provided that the developments or
inventions resulting from such project may not be used by Stericycle, or sold or
licensed by Stericycle to third parties for use, in connection with any products
competitive with any Baxter Products.

     4.4.   FUNDING; ACCOUNTING. (a) Stericycle, at the direction of the

Research and Development Program (the "Alliance Research and Development Fund")
in an interest-bearing account.

     (c)    Funding for Alliance Research and Development Program projects shall
be approved (together with a budget and forecasted payment schedule (the
"Budget")) by the Committee on a project by project basis prior to the time a
project is undertaken.  Funds shall be released from the Alliance Research and
Development Fund on an item by item basis for payment of items contemplated by
the Budget at such time as the actual costs for such item become payable.  Any
expense which is incurred in connection with any Alliance Research and
Development Program project and which is not contemplated by such project's
Budget may not be paid from the Alliance Research and Development Fund unless
and until it is approved by the Committee.  All individual (or series of
related) capital expenditures in excess of [    *     ] (whether or not
contemplated by the Budget) shall be approved a second time by the Committee
prior to payment from the Alliance Research and Development Fund.

     (d)    Costs chargeable to the Alliance Research and Development Fund shall
be the following direct costs attributable to Alliance Research and Development
Program projects which have been approved by the Committee in accordance with
Section 4.4(c) of this Agreement:

            1.      Documentable out-of-pocket costs as evidenced by invoices or
     receipts received from independent third parties, or, if not supported by
     such invoices or receipts, specifically approved in advance by the
     Committee; and

            2.      Salary or allocated costs for Stericycle employees as
     approved in advance by the Committee.

     4.5.   ADDITIONAL RESEARCH AND DEVELOPMENT FUNDING.  Upon Stericycle's
request made six or more months after the date hereof, Baxter shall consider
(taking into account the progress of the Alliance Research and Development
Program) providing additional funding to the Alliance Research and Development
Program, which funding may be provided by way of an equity investment in
Stericycle or otherwise.

     4.6.   BAXTER RIGHTS WITH RESPECT TO THE ALLIANCE TECHNOLOGY.  (a) In each
instance, for a period of five years after any Alliance Technology becomes
commercially viable or, if longer, the duration of the Alliance (the
"Exclusivity Period"), Stericycle shall not (1) make any Alliance Technology
available (by way of sale, license or otherwise) to any party (other than Baxter
and its affiliates and its suppliers solely for use in Baxter Products) within
the continental United States for use in connection with the production of raw
materials to be incorporated into products competitive with any Baxter Products,
or (2) except as permitted pursuant to Sections 6.2(a) (sales to SAGE) and
6.2(b) of this Agreement, sell

any party (other than Baxter and its affiliates and its suppliers solely for use
in Baxter Products) within the continental United States any recycled raw
materials produced using the Alliance Technology for use in connection with
products competitive with any Baxter Products.

     (b)    If at any time during the duration of the Alliance, Stericycle is
unable to satisfy Baxter's reasonable requirements for recycled raw materials
for use in Baxter Products, at Baxter's request, Stericycle shall grant Baxter
or other parties royalty-free, non-exclusive licenses to use the Alliance
Technology for the sole purpose of producing recycled raw materials for use in
Baxter Products.

     (c)    If at any time (during or after the duration of the Alliance),
Stericycle, in a manner permitted by this Agreement or otherwise with the
consent of the Committee, (i) makes the Alliance Technology available (by way of
sale, license or otherwise) to any party (other than Baxter and its affiliates
and its suppliers) within the continental United States (whether or not for use
in connection with the production of raw materials to be incorporated into
products which are competitive with Baxter Products), or (ii) sells (including
sales pursuant to Sections 6.2(a) (sales to SAGE) and 6.2(b) of this Agreement)
any party (other than Baxter and its affiliates and its suppliers) within the
continental United States any recycled raw materials produced using the Alliance
Technology (whether or not for use in connection with products which are
competitive with Baxter Products), Baxter and Stericycle shall share the
resulting revenues as follows:

            1.      In the case of any sale or licensing of Alliance Technology,
     Baxter and Stericycle shall share the gross proceeds of such sale (net of
     the reasonable transaction expenses relate to such sale) or the gross
     licensing income on a [      *       ]; and

            2.      In the case of any sale of any recycled raw materials
     produced using the Alliance Technology, Stericycle shall pay Baxter a
     royalty equal to [        *         ] of Stericycle's gross revenues from
     such sale.

     (d)    Upon the conclusion of the Exclusivity Period, Stericycle shall
grant Baxter a License, subject to the forfeiture provisions of section 7.7(a)
of this Agreement.

     (e)    After the conclusion of the Exclusivity Period, except with respect
to prior sales or licenses of Alliance Technology and sales of recycled raw
materials produced using Alliance Technology (and outstanding commitments
therefor) made in accordance with and not in violation of this Agreement,
Stericycle shall not (i) make any Alliance Technology available (by way of sale,
license or otherwise) to any party (other than Baxter and its affiliates and
suppliers solely for use in Baxter Products) within the continental

United States for use in connection with the production of raw materials to be
incorporated into products competitive with any Baxter Products, or (ii) except
as permitted pursuant to Sections 6.2(a) (sales to SAGE) and 6.2(b) of this
Agreement, sell any party (other than Baxter and its affiliates and its
suppliers solely for use in Baxter Products) any recycled raw materials produced
using the Alliance Technology for use in connection with products competitive
with any Baxter Products, unless Stericycle first:

            1.      Advises Baxter in writing of the nature of the proposed
     transaction and the identity of the prospective purchaser or licensee, if
     any;

            2.      Offers such Alliance Technology (and all of Stericycle's
     rights with respect thereto, including all rights to receive payment of
     royalties), or at Baxter's option, an exclusive license of such Alliance
     Technology (subject only to the then existing licenses thereof) to Baxter;

            3.      Negotiates in good faith with Baxter concerning Stericycle's
     offer, provided that, within 30 days after Baxter's receipt of such offer,
     Baxter notifies Stericycle of Baxter's desire to negotiate concerning such
     offer; and

            4.      Completes the proposed transaction with the proposed
     purchaser or licensee or another purchaser or licensee (on terms no more
     favorable to such purchaser or licensee than those offered to Baxter)
     within 60 days after the earlier of (A) the date of Baxter's notice to
     Stericycle that Baxter does not desire to acquire the Alliance Technology
     or an exclusive license thereto, (B) the 30th day after Baxter's receipt of
     Stericycle's offer, if Baxter does not notify Stericycle of Baxter's desire
     to negotiate concerning such offer within such 30-day period, and (C) the
     date of the termination of negotiations between Baxter and Stericycle
     concerning Stericycle's offer, if, after good faith negotiation for a
     period of at least 60 days from the date Baxter notifies Stericycle that
     Baxter desires to negotiate concerning Stericycle's offer, Baxter and
     Stericycle are unable to reach an agreement concerning the terms of the
     sale or license of the Alliance Technology to Baxter.

If Baxter does not acquire the Alliance Technology or an exclusive license
thereto pursuant to the foregoing offer, the License shall continue on a
non-exclusive basis, subject to the forfeiture provisions of Section 7.7(a) of
this Agreement.

     4.7.   PROTECTION OF THE ALLIANCE TECHNOLOGY.  (a) Stericycle shall
disclose all developments and inventions resulting from the Alliance Research
and Development Program to the Committee for determination of patent potential
and authorization of expenditures relating to patentability or other appropriate
protection.  Stericycle, subject to the direction of the Committee, shall timely


                                        - 7 -

<PAGE>

take all necessary steps to protect the Alliance Technology and shall not grant
any Encumbrances with respect to, or allow any Encumbrances to be placed upon,
the Alliance Technology without the approval of the Committee, except the
permitted liens set forth in SCHEDULE 4.7 to this Agreement.

     (b)    If Baxter and Stericycle (acting through their respective
representatives on the Committee) both vote against seeking patent (or other
appropriate) protection of any development or invention, such development or
invention shall remain Alliance Technology, but Stericycle shall not seek such
protection with respect thereto.

     (c)    If either Baxter or Stericycle (acting through their respective
representatives on the Committee) votes against seeking patent (or other
appropriate) protection of any development or invention and the Committee
determines that such development or invention IS NOT related to the purposes of
the Alliance, the party voting in favor of seeking such protection, at its sole
cost and expense, shall have the right to seek such protection.  If such party
elects to seek such protection (and in good faith prosecutes the patent
application (or other appropriate registration or filing) with respect thereto)
and reimburses the Alliance Research and Development Fund for the reasonable
development costs of such development or invention, such development or
invention SHALL NOT be Alliance Technology and the party voting against seeking
such protection shall cooperate in all reasonable respects with the prosecution
of the patent application (or other appropriate registration or filing) and
assign all of its rights in such development or invention to the other party.


SECTION 5. DISPOSAL SERVICES.

     5.1.   BAXTER NOT ENGAGED IN COLLECTION, TRANSPORTATION, TREATMENT OR
DISPOSAL SERVICES.  Without limiting Baxter's obligations under this Agreement,
although Baxter's customers may purchase the Disposal Services from Stericycle
in connection with the PBDS, Baxter is not, and does not intend to be or become
or be deemed to be, engaged in the collection, transportation, treatment or
disposal of Infectious Medical Waste, the sale of collection, transportation,
treatment or disposal services with respect to Infectious Medical Waste, or the
arrangement for the collection, transportation, treatment or disposal of
Infectious Medical Waste by virtue of this Agreement or the Alliance and nothing
in this Agreement shall be construed to the contrary.

     5.2.   STERICYCLE EXCLUSIVITY.  Stericycle shall not within the continental
United States provide collection, transportation, treatment and disposal
services with respect to Infectious Medical waste in connection with any
PBDS-Like Product.

     5.3.   BAXTER EXCLUSIVITY; EXCEPTIONS.  (a) Baxter may offer the PBDS to
any customer without also offering the customer the option of selecting the
Disposal Services in connection therewith; but, in connection with, or as part
of, the PBDS, Baxter shall not offer a customer the option of selecting
collection, transportation, treatment and disposal services within the
continental United States that are provided by a party other than Stericycle.

     (b)    Notwithstanding the foregoing, Baxter may offer its customers the
option of selecting collection, transportation, treatment and disposal services
in connection with the PBDS provided by a party other than Stericycle: (1) if
collection, transportation, treatment and disposal services (which include the
recycling of Infectious Medical Waste) are developed by any other party which
render the Stericycle recycling process, in Baxter's reasonable judgment,
noncompetitive, or (2) with respect to any Baxter customer, if (i) Stericycle
does not have the technical or administrative capability to provide the Disposal
Services or any administrative services related thereto to such customer, (ii)
Stericycle does not have a facility which is reasonably accessible to such
customer, or (iii) there is any Law which prevents the transportation of
Infectious Medical Waste from such customer's facility to a Stericycle facility.

     5.4.   PRICING OF THE DISPOSAL SERVICES; BILLING.  (a) During an initial
test market period (which will conclude no later than March 31, 1994 or such
later date as determined by the Committee) for the Disposal Services, Stericycle
shall charge [                                                                  
                                                                                
                                                                                
                *

                          *

     (c)    So long as the Alliance continues, Stericycle and Baxter shall use
their respective good faith reasonable efforts to reduce their respective costs
for providing the PBDS and the Disposal Services in connection therewith and
Baxter and Stericycle [

other basis or at such other times as determined by the Committee.  Subject to
the right in good faith to dispute the charges reflected on such invoices, the
charges reflected on such invoices shall be payable within 30 days after the
date of the invoice.  As a convenience to Baxter's customers, Baxter's charges
for the PBDS and Stericycle's charges for the Disposal Services shall be billed
to the customer on a single invoice.

     5.5.   STERICYCLE'S RELATIONSHIP WITH BAXTER'S PBDS CUSTOMERS.  Stericycle
shall [             *          ] with each of Baxter's customers electing the
Disposal Services in connection with the PBDS on terms that are reasonably
satisfactory to Baxter and such customer (including indemnification provisions
substantially like the indemnification provisions contained in this Agreement
(Section 8.1) with respect to the Disposal Services).  As soon as practicable
after the date hereof, Stericycle shall develop, in consultation with Baxter, a
form of customer contract to be used by Stericycle in connection with the
Disposal Services.  Stericycle shall remove all Infectious Medical Waste from
such customer's facility at such times as may be agreed upon by Stericycle and
such customer and provide such other services associated with the handling,
management, collection, transportation, treatment and disposal of Infectious
Medical Waste as such customer may reasonably request.  Stericycle shall make
available to each of Baxter's customers electing the Disposal Services in
connection with the PBDS such service representatives and technical support as
Baxter or such customer may from time to time reasonably request.

     5.6.   MARKETING SURPORT.  (a) Stericycle shall provide marketing,
advertising and sales literature concerning its services related to the
handling, management, collection, transportation, treatment, disposal and
recycling of Infectious Medical Waste in such quantities as may be reasonably
requested by Baxter and such other marketing, advertising and sales support as
may be reasonably requested by Baxter.  If the Committee deems it necessary,
Baxter and Stericycle shall jointly develop marketing, advertising and/or sales
literature describing the Disposal Services customers may select in connection
with the PBDS. In conjunction with the marketing and advertising of the Disposal
Services offered in connection with the PBDS, Baxter shall not use or
disseminate any literature describing Stericycle's services (other than
literature prepared and provided to Baxter by Stericycle) unless Stericycle has
in writing consented (which consent shall not be unreasonably withheld) to the
use of such literature.

facilities located within the continental United States (excluding those used
for the SAGE products and processed using the Stericycle Technology or the
technology currently jointly owned by Stericycle and SAGE) for use in Baxter
Products.

     (b)    If Stericycle produces more recycled material than Baxter requires,
subject to Section 4.6(c) of this Agreement, Stericycle may provide such excess
materials to other parties for product production, so long as the products in
which such materials are used do not compete with any Baxter Product.

     6.3.   PRICING.  The price to Baxter of recycled raw materials shall be
determined as follows:

     (a)    [

     (c)    The development by any other party of collection, transportation,
treatment and disposal services (which include the recycling of Infectious
Medical Waste) which render the Stericycle recycling process, in Baxter's
reasonable judgment, noncompetitive;

     (d)    The general lack of capacity by Stericycle to satisfy the Disposal
Services needs of Baxter's PBDS customers having facilities located in regions
serviced by Stericycle, the general dissatisfaction of Baxter's customers with
the services provided by Stericycle, or the general lack of capacity by
Stericycle to provide to Baxter the types and amounts of recycled raw materials
as from time to time specified by the Committee; or

     (e)    Baxter determining in its sole and absolute discretion for any
reason (whether based on concern about legal liability, reputational damage or
otherwise) that it is dissatisfied or uncomfortable in any respect with the
management by Stericycle or any of Stericycle's Subcontractors or any party
hired or otherwise retained to assist in the provision of the services offered
by Stericycle (which if directly hired or retained by Stericycle would have been
a Subcontractor) of their respective environmental or employee health and safety
related affairs, their respective storage, handling, collection, transportation,
treatment or disposal of Infectious Medical Waste or Contaminants, the
conditions at any of their respective facilities with respect to environmental
or employee health and safety matters, or their compliance (or efforts or
attempts to comply) with environmental or employee health and safety Laws.

     7.5.   TERMINATION BY STERICYCLE.  The Alliance may be terminated at any
time by Stericycle by written notice to Baxter of the occurrence of any of the
following events given, in the case of subsections (b) and (c), within 180 days
after Stericycle first becomes (or reasonably should have become) aware of such
event, or, in any other case, at any time after:

     (a)    The failure by Baxter (or its suppliers), at any time after the
Alliance has been in existence for more than 18 months, to purchase at least the
types and amounts of recycled raw materials from the Waste Stream using the
Alliance Technology as are from time to time specified by the Committee and are
suitable for incorporation in Baxter Products;

     (b)    The termination by Baxter pursuant to Section 5.3(b)(1) of this
Agreement of Stericycle's exclusivity with respect to the provision of
collection, transportation, treatment and disposal services in connection with
the PBDS as a result of the development by a party other than Stericycle of
collection, transportation,


                                        - 13 -

<PAGE>

treatment and disposal services (which include the recycling of Infectious
Medical Waste) which render the Stericycle recycling process, in Baxter's
reasonable judgement, noncompetitive; or

     (c)    A Stericycle Competitive Event.

     7.6.   CONSEQUENCES OF EARLY TERMINATION.  (a) Any notice of termination of
the Alliance given by Baxter pursuant to Section 7.3(a) (as a result of a
willful breach or default by Stericycle) or 7.4(a) of this Agreement shall
describe the basis upon which Baxter believes that it is entitled to terminate
the Alliance pursuant to such Section.  If the Alliance is terminated by Baxter
pursuant to Section 7.3(a) (as a result of a willful breach or default by
Stericycle) or 7.4(a) of this Agreement, promptly upon such termination,
Stericycle shall transfer the Alliance Technology and all of Stericycle's rights
therein (including all rights to receive royalty payments) to Baxter and
thereafter, for a period of 180 days, Baxter shall be entitled to "put" all, but
not less than all, of the Stericycle Shares to Stericycle (without the other
stockholders having a right to participate in the redemption) at their
Liquidation Value plus all accumulated and unpaid dividends thereon (determined
in accordance with Stericycle's Charter) through the date of redemption
("Special Redemption Rights").  In connection with the Special Redemption
Rights, Stericycle shall pay Baxter the full amount of the redemption price in a
single lump-sum cash payment within 45 days after the date of Baxter's written
notice to Stericycle of the exercise of the Special Redemption Rights. 
Contemporaneously with the payment of the redemption price by Stericycle, Baxter
shall deliver to Stericycle the certificates representing the Stericycle Shares
and a duly executed assignment transferring the Stericycle Shares to Stericycle
free and clear of Encumbrances (other than restrictions under federal and state
securities laws).

     (b)    Any notice of termination of the Alliance given by Stericycle
pursuant to Section 7.3(a) (as a result of a willful breach or default by
Baxter) or 7.5(c) of this Agreement shall describe the basis upon which
Stericycle believes that it is entitled to terminate the Alliance pursuant to
such Section.  If the Alliance is terminated by Stericycle pursuant to Section
7.3(a) (as a result of a willful breach or default by Baxter) or 7.5(c) of this
Agreement, promptly upon such termination, Baxter shall transfer all of its
rights in the Alliance Technology to Stericycle (and Baxter's rights to receive
payments under Sections 4.6(c) and 9.1(d) of this Agreement shall immediately
terminate) and thereafter, for a period of 180 days, Stericycle will be entitled
to "call" all, but not less than all, the Stericycle Shares at their Liquidation
Value (the "Call Rights").  In connection with the Call Rights, Stericycle shall
pay Baxter the full amount of the redemption price in a single lump-sum cash
payment within 15 days after the date of Stericycle's written notice to Baxter
of the exercise of the Call Rights.  Contemporaneously with the payment of the
redemption price by Stericycle, Baxter shall deliver to


                                        - 14 -

<PAGE>

Stericycle the certificates representing the Stericycle Shares and a duly
executed assignment transferring the Stericycle Shares to Stericycle free and
clear of Encumbrances (other than restrictions under federal and state
securities laws).

     (c)    If the Alliance is terminated by Baxter pursuant to Section 7.3(a)
(other than as a result of a willful breach or default by Stericycle), 7.3(b),
7.3(c), 7.4(b), 7.4(c), 7.4(d), or 7.4(e) of this Agreement, or by Stericycle
pursuant to Section 7.3(a) (other than as a result of a willful breach or
default by Baxter), 7.3(b), 7.3(c), 7.5(a), or 7.5(b) of this Agreement,
promptly upon such termination, Stericycle shall grant Baxter a License on a
non-exclusive basis and, except as provided in Section 7.7 of this Agreement,
Baxter WILL NOT be entitled to the Special Redemption Rights and Stericycle WILL
NOT be entitled to the Call Rights.

     7.7.   POST-TERMINATION FORFEITURE OF RIGHTS TO ALLIANCE TECHNOLOGY;
POST-TERMINATION SPECIAL REDEMPTION RIGHTS AND CALL RIGHTS.  (a) Provided
(except in the case of a termination of the Alliance by Baxter pursuant to
Section 7.4(e) of this Agreement) that a Baxter Competitive Event shall not have
first occurred, if at any time within 18 months after the termination of the
Alliance by Baxter pursuant to Section 7.3(a) (other than as a result of a
willful breach or default by Stericycle), 7.3(c), 7.4(b), 7.4(c), or 7.4(e) of
this Agreement or the non-renewal of the Alliance by Baxter, a Stericycle
Competitive Event occurs, Baxter's rights with respect to the Alliance
Technology shall automatically be transferred to Stericycle (and Baxter's rights
to receive payments under Sections 4.6(c) and 9.1(d) of this Agreement shall
immediately terminate) and, for a period of 180 days after the date Stericycle
reasonably should have become aware of such event, Stericycle shall be entitled
to exercise the Call Rights.

     (b)    Provided that a Stericycle Competitive Event shall not have first
occurred, if at any time within 18 months after the termination of the Alliance
by Stericycle pursuant to Section 7.3(a) (other than as a result of a willful
breach or default by Baxter), 7.3(c) or 7.5(b) of this Agreement or the
non-renewal of the Alliance by Stericycle, a Baxter Competitive Event occurs,
all of Stericycle's rights with respect to the Alliance Technology (including
all rights to receive royalty payments) shall automatically be transferred to
Baxter and, for a period of 180 days after the date Baxter reasonably should
have become aware of such event, Baxter shall be entitled to exercise the
Special Redemption Rights.

     7.8.   POST-TERMINATION C00PERATION.  Following any termination or
non-renewal of the Alliance: (a) Baxter and Stericycle shall cooperate with each
other in good faith to, in an orderly manner, notify the PBDS customers which
have elected the Disposal Services of the cessation of the Alliance and the
effect of such cessation upon such customers and arrange for the


                                        - 15 -

transition of the billing of such customers for the Disposal Services; (b)
Stericycle shall continue to provide the Disposal Services to such customers on
the terms of the contracts between Stericycle and such customers until such time
as such customers make other arrangements for the provision of collection,
transportation, treatment and disposal services with respect to Infectious
Medical Waste; and (c) such customers may terminate their agreements with
Stericycle at any time.

     7.9.   SURVIVAL OF CERTAIN PROVISIONS OF THIS AGREEMENT.  Notwithstanding
anything in this Agreement to the contrary, the parties' respective rights and
obligations under Sections 2.3, 4.6(d), 5.1, 7.7, 7.8, 7.9, 8, 9.6, 9.7 and 11,

or default by Baxter), 7.4(e) or 7.5(c)) 4.6(a) and 4.6(e), of this Agreement,
as well as all payment obligations arising on or before the date of the
termination or expiration of the term of the Alliance, shall survive such
termination or expiration; provided, however, that the rights and obligations of
Baxter and Stericycle with respect to indemnification pursuant to Sections
8.2(a)(4) and (5) and 8.2(b)(3) and (4) of this Agreement shall terminate and
cease to be of any further force or effect upon the second anniversary of the
termination or expiration of the term of the Alliance and all notices of claims
thereunder must be given on or before such second anniversary.

     8.1.   STERICYCLE DISPOSAL SERVICES INDEMNITY.  Without limitation of any

contrary, from and after the date of this Agreement, Stericycle promptly shall
indemnify, defend and hold harmless Baxter and each of its PBDS customers which
elect the Disposal Services and each of its and their respective directors,
officers, employees and representatives (individually, a "Disposal Indemnified
Party") from and against any and all Damages suffered or incurred by a Disposal
Indemnified Party resulting from, arising out of, in connection with, or

operated by Stericycle or any of its Subcontractors into the indoor or outdoor
environment, or (c) any actual or alleged injury or damage to persons (including
any Stericycle employees) or property caused by any actual or alleged acts or

officer, employee or representative of any Baxter customer, to the extent that
any Disposal Matter specifically results from, arises out of, is in connection
with or relates to any acts or omissions (other than those taken pursuant to
instructions or directions given by Stericycle or any of its directors,

negligent) of such Baxter customer or any of its directors, officers, employees
or representatives.

     8.2.   MUTUAL INDEMNITY.  (a) Without limitation of any other provision
hereof, from and after the date of this Agreement, Stericycle promptly shall

     intellectual property rights of a specified third party or (ii)
     Improvements (but only to the extent of such Improvements) developed by
     Baxter);

            4.      Any warranty or representation made by Stericycle in this

Notwithstanding the foregoing, Stericycle shall have no obligation to indemnify,
defend or hold harmless any Baxter Indemnified Party with respect to any Baxter
Matter specifically resulting from, arising out of, in connection with, or
relating to any Baxter Product (which shall not include the Disposal Services in
connection with the PBDS or recycled raw materials provided by Stericycle and
incorporated in Baxter Products which are defective or which are infectious when
provided to Baxter).

     (b)    Without limitation of any other provision hereof, from and after the
date of this Agreement, Baxter promptly shall indemnify, defend and hold
harmless Stericycle and each of its directors, officers, employees and
representatives (individually, a "Stericycle Indemnified Party") from and
against any and all Damages suffered or incurred by a Stericycle Indemnified

the following (a "Stericycle Matter"):

            1.      Baxter's business, assets or properties or the ownership or
     operation thereof before the commencement, during the duration, or after
     the termination, of the Alliance;

            2.      Any willful misconduct or gross negligence by Baxter or any
     of its directors, officers, employees or representatives in connection with
     the Alliance;

            3.      Any warranty or representation made by Baxter in this
     Agreement being incorrect or untrue at the time made;

            4.      Baxter's breach of any covenant or agreement made by Baxter
     in this Agreement; or

            5.      Any infringement or alleged infringement by the Alliance
     Technology upon the intellectual property rights of any third party arising
     out of Baxter's use of the Alliance Technology or production or sale of
     Baxter Products using the Alliance Technology in any jurisdiction of which
     Stericycle has given Baxter written notice that Stericycle in good faith
     reasonably believes the use of the Alliance Technology or the production or
     sale of products using the Alliance Technology would infringe upon the
     intellectual property rights of a specified third party.

Notwithstanding the foregoing, Baxter shall have no obligation to indemnify,
defend or hold harmless any Stericycle Indemnified Party with respect to any
Stericycle Matter specifically resulting from, arising out of, in connection
with, or relating to the Disposal Services or any other Stericycle product or
service.

     8.3.   INDEMNITY PROCEDURES.  An Indemnified Party shall give written
notice to the party which is required to provide indemnification hereunder (an
"Indemnifying Party") within thirty


                                        - 18 -

<PAGE>

days from discovery by the Indemnified Party of any claim, demand or suit by a
third party which may give rise to a claim for indemnification hereunder (a
"Claim"), but the failure to so notify the Indemnifying Party shall not release
the Indemnifying Party from any liability hereunder (except to the extent that
such failure prejudices the Indemnifying Party with respect to such Claim).  The
Indemnifying Party shall have the right to defend against any such Claim
provided (a) the Indemnifying Party shall, within 20 days after the giving of
such notice by the Indemnified Party, notify the Indemnified Party that the
Indemnifying Party shall, at its own cost and expense, defend the same, and (b)
such defense is instituted and continuously maintained in good faith by the
Indemnifying Party.  The Indemnifying Party shall not settle any Claim without
the written consent of the Indemnified Party (which consent shall not be
unreasonably withheld).  The Indemnified Party may, if it so elects, designate
its own counsel to participate along with counsel selected by the Indemnifying
Party in the conduct of such defense, and the Indemnified Party shall, in such
event, pay the fees of any counsel so designated by the Indemnified Party.  In
any event, the Indemnified Party shall be kept fully advised as to the status of
such defense.  If the Indemnifying Party shall be given notice of a Claim as
aforesaid and shall fail to notify the Indemnified Party of its election to
defend such Claim within the time and as prescribed herein, or after having so
elected to defend such Claim shall fail to institute and continuously maintain
such defense in good faith, the Indemnified Party shall have the right to
negotiate, settle (unless such settlement involves the admission of guilt by the
Indemnifying Party or imposes any injunctive remedy against the Indemnifying
Party, in which case, the consent (which shall not be unreasonably withheld) of
the Indemnifying Party shall be required) or defend such Claim (a "Rejected
Claim") at the Indemnifying Party's cost and expense (including reasonable fees
and expenses of the Indemnified Party's counsel) and the Indemnifying Party
shall, at the request of the Indemnified Party, cooperate with the Indemnified
Party with respect thereto. If the defense of any Claim indemnified against
hereunder by the Indemnifying Party shall be unsuccessful or if the Indemnified
Party shall have negotiated, settled or defended (successfully or
unsuccessfully) any Rejected Claim as aforesaid, then, in any such event, if the
Indemnified Party is entitled to indemnification under this Section 8, the
Indemnifying Party shall, within 10 days after notice from the Indemnified Party
requesting the Indemnifying Party to do so, fully satisfy and discharge the
Claim, settlement or Rejected Claim and reimburse the Indemnified Party for all
costs and expenses paid or incurred by the Indemnified Party with respect to
such Claim, settlement or Rejected Claim to the extent provided in this Section
8.

     to negotiate concerning such offer within such 30-day period, and (C) the
     date of the termination of negotiations between Baxter and Stericycle
     concerning Stericycle's offer, if, after good faith negotiation for a
     period of at least 60 days from the date Baxter notifies Stericycle that
     Baxter desires to negotiate concerning Stericycle's offer, Baxter and
     Stericycle are unable to reach an agreement concerning the terms of such
     license or such purchase.

     (d)    If Stericycle, at any time during or after the duration of the
Alliance, in a manner permitted by this Agreement makes the Alliance Technology
available (by way of sale, license or otherwise) to any party in any Non-U.S.

those pertaining to environmental and employee health and safety matters) which
Stericycle is required to make, file, obtain and/or maintain under applicable
Laws in connection with the ownership of its assets and properties or the
operation of its business (including, without limitation, the Disposal Services
and the Recycling Services), except to the extent that any failure to comply
with Laws or to make, file, obtain or maintain any Permit could not reasonably
be expected to have a material adverse effect upon Stericycle's ability to
perform its obligations under this Agreement or any material adverse effect upon
Baxter or any of its customers or suppliers.

     9.3.   PERIODIC ENVIRONMENTAL AND EMPLOYEE HEALTH AND SAFETY REVIEWS.  At
least once per year, Stericycle shall perform an audit of its compliance with
environmental and employee health and safety Laws.  During the first 18 months
of the Alliance, Stericycle shall cause an independent third party to perform an
audit or audits of its compliance with environmental and employee health and
safety laws.  The costs to Stericycle of such audits shall be no more than
$20,000 with any additional costs to be shared equally by Baxter and Stericycle.
Subsequent to the initial 18 month period, similar audits shall be performed as
necessary as determined by the Committee.  The annual costs shall be borne by
Stericycle but Stericycle shall not be required to pay any amount in excess of
$10,000 per year; provided, however, this amount may be adjusted from time to
time by the Committee if additional facilities are brought on line, or if
significant compliance problems are identified.  Stericycle shall provide Baxter
with a copy of the audit reports resulting from the audits referred to in this
Section 9.3 and an explanation of Stericycle's proposed actions to address any
concerns raised by the audits.

     9.4.   NO RELEASES OF CONTAMINANTS.  Stericycle shall not release any
Contaminant into the indoor or outdoor environment in violation of any
applicable Laws from any Stericycle facility.

     9.5.   NO USE OF BAXTER'S NAME ON PERMITS.  Stericycle shall not use or
permit Baxter's name to be used or appear on any Permits or other documents
related to the Disposal Services, unless otherwise required by applicable Laws
(and then only after consultation with Baxter and permitting Baxter to
communicate with the appropriate agency concerning such use of Baxter's name).

     9.6.   INSURANCE.  Stericycle shall maintain during the term of the
Alliance and for a period of two years after any nonrenewal or termination of
the Alliance such amounts and types of insurance coverage with such insurers as
are comparable for established, well-insured and reputable companies in
Stericycle's business and are prudent covering Stericycle with respect to


                                        - 23 -

<PAGE>

matters occurring during the term of the Alliance, but in no event less that the
following coverages:

     (a)    Pollution Legal Liability in an amount not less than $1,000,00 each
loss/$2,000,000 total of all losses with an aggregate annual deductible not to
exceed $100,000;

     (b)    Comprehensive General Liability in an amount not less than
$2,000,000 each occurrence combined single limit for bodily injury and property
damage with an aggregate annual deductible not to exceed $10,000 to include:

                 (i)     premises-operations;
                (ii)     products/completed operations;
               (iii)     blanket contractual liability; and
                (iv)     personal injury;

     (c)    Comprehensive Automobile Liability for owned, hired and non-owned
motor vehicles in an amount not less than $1,000,000 each occurrence combined
single limit bodily injury and property damage with an aggregate annual
deductible not to exceed $5,000 or, at any time after Stericycle commences
directly transporting Infectious Medical Waste or other waste materials (as
opposed to engaging Subcontractors to do so), not less than $3,000,000 each
occurrence combined single limit bodily injury and property damage with an
annual aggregate deductible not to exceed $10,000;

     (d)    Workers Compensation, occupational diseases and disability benefits
in accordance with applicable statutory requirements without any deductible; and

     (e)    Employer's Liability in an amount not less than $1,000,000 with an
aggregate annual deductible not to exceed $10,000.

Baxter shall be named as an additional insured on all such insurance policies
(excluding Workers' Compensation).  Stericycle shall provide Baxter with
certificates of insurance evidencing Stericycle's insurance coverage satisfying
the foregoing requirements and providing that at least 30 days' written notice
shall be provided to Baxter prior to any cancellation, expiration, non-renewal,
or material change affecting the insurance coverage, other than the cancellation
of such coverage contemporaneously with or after the effectiveness of comparable
replacement coverage from a comparable insurer.  Notwithstanding the foregoing,
the provisions of this Section 9.6 shall not be effective until the 10th
business day after the date of this Agreement (on or before which date
Stericycle shall deliver to Baxter insurance certificates evidencing the
insurance coverage required by this Section 9.6); provided, however, that,
during such 10-business day period, Stericycle shall maintain in force and
effect the


                                        - 24 -

<PAGE>

insurance coverages evidenced by the insurance certificates heretofore delivered
to Baxter.

     9.7.   CONFIDENTIALITY.  (a) Subject to Section 11.13 of this Agreement,
Baxter, on one hand, and Stericycle, on the other hand, shall not, and shall use
their respective reasonable efforts to cause their respective directors,
officers, employees and representatives to not: (1) use any information or
materials concerning the other party or, except as otherwise contemplated by
this Agreement, the Alliance ("Confidential Material") for any purpose other
than carrying-out the Alliance; (2) disclose any portion of the Confidential
Material to any person, except as reasonably necessary to carry-out the purposes
of the Alliance or to protect such party's rights under this Agreement; or (3)
make copies of the Confidential Material, except as reasonably necessary to

this Agreement.

     (b)    Notwithstanding the foregoing, Confidential Material shall not

disclosing party reasonably believes it is required by applicable Laws to
disclose (but only to the extent of such required disclosure and only to the
extent disclosed to the parties to which such disclosure is required to be
made).

     9.8.   USE OF TRADEMARKS, ETC.  Baxter may use Stericycle's trade names,
trademarks and service marks in conjunction with the marketing and advertising
of the Disposal Services offered in connection with the PBDS (subject to Section
5.6(a) of this Agreement and the reasonable supervision and control by
Stericycle of the use of such names and marks).  Stericycle may not use Baxter's
trade names, trademarks or service marks without Baxter's written consent.

     9.9.   ASSIGNMENTS OF INTELLECTUAL PROPERTY RIGHTS.  Stericycle shall
obtain, and make available to Baxter upon request therefor, appropriate
assignments (which are in a form reasonably satisfactory to Baxter) from all
employees and independent contractors who participate in or contribute in any
manner to the development or invention of patentable subject matter, trade
secrets or other proprietary information in connection with, or relating to, the
Alliance Research and Development Program.

     9.10.  FINANCIAL RECORDS.  Stericycle shall maintain financial books and
records in accordance with good business practices (and, where appropriate, in
accordance with GAAP) and, upon request,


                                        - 25 -

<PAGE>

permit Baxter to review and inspect such books and records at Stericycle's
executive offices during regular business hours to confirm the Research and
Development expenditures, Disposal Services charges and Recycling Services
charges (and Stericycle's costs therefor).

     9.11.  SUBCONTRACTORS.  Stericycle shall use its reasonable efforts to
obtain contractual agreements from each of its Subcontractors engaged after the
date hereof (a) to the effect that such Subcontractor shall (1) comply with all
applicable Laws, (2) make, file, obtain and maintain all required Permits, and
(3) give Stericycle written notice of the occurrence in relation to such
Subcontractor or the services to be performed by such Subcontractor of any of

concerning environmental or employee health and safety matters, and (b) which
permit Stericycle to terminate the contract if the Subcontractor breaches in any
material respect any of the provisions referred to in subsections (a)(1), (2)
and (3) of this Section 9.11. In addition, Stericycle shall use its reasonable
efforts (without any obligation to pay additional consideration therefor) to

benefit of Stericycle, Baxter, Baxter's customers and their respective
directors, officers, employees and representatives on substantially the terms of
Section 8.1 of this Agreement.

representatives or agents, in each case, related to the Alliance.

     9.13.  NOTICE OF CERTAIN EVENTS.  Stericycle, promptly after the Stericycle
Officers acquire (or reasonably should have acquired) knowledge thereof, shall
notify Baxter in writing of any of the following which are connected with, or
arising from, any activities, services or operations of Stericycle or
Stericycle's Subcontractors in connection with the Disposal Services, the
Recycling Services or the Alliance Research and Development Program: (a) any

or the Alliance Agreement or to protect such party's rights under this
Agreement; or (3) make copies of the Confidential Material, except as reasonably

apply for or seek any patent (or other appropriate) protection with respect to
any Improvement to the Alliance Technology developed during the 18-month period
immediately following the Effective Date shall rest with Stericycle.  If
Stericycle elects to apply for or seek such patent (or other appropriate)
protection, the cost of preparing, filing and prosecuting the application,
registration or filing with respect thereto shall be paid by Stericycle.  If
Stericycle elects not to apply for or seek, or does not diligently prosecute,
such patent (or other appropriate) protection with respect to such Improvement,

If Baxter elects to apply for or seek such patent (or other appropriate)
protection, the cost of preparing, filing and prosecuting the application,
registration or filing with respect thereto shall be paid by Baxter and, if

filing with respect thereto, Stericycle shall cooperate in all reasonable
respects with such prosecution and assign a 50% undivided interest in
Stericycle's rights in such Improvement to the Baxter.

Alliance Technology upon the rights of any third party or any infringement by
any third party of any of the Alliance Technology.  Without limitation of any
other provision of this Agreement, from and after the Effective Date: (a)
Stericycle promptly shall indemnify, defend and hold harmless Baxter and each of
its directors, officers, employees, representatives and Sublicensees from and
against any and all Damages resulting from, arising out of, in connection with
or relating to any infringement or alleged infringement by the Alliance
Technology upon the rights of any third party (other than any infringement or
alleged infringement arising out of (i) Baxter's use of the Alliance Technology
in any jurisdiction of which Stericycle has given Baxter written notice that
Stericycle in good faith reasonably believes the use of the Alliance Technology
or the production or sale of products using the Alliance Technology would
infringe upon the intellectual property rights of a specified third party or
(ii) Improvements (but only to the extent of such Improvements) developed by
Baxter; and (b) Baxter promptly shall indemnify, defend and hold harmless
Stericycle and each of its directors, officers, employees and representatives

<PAGE>

upon the intellectual property rights of any third party arising out of Baxter's
use of the Alliance Technology or production or sale of Baxter Products using
the Alliance Technology in any jurisdiction of which Stericycle has given Baxter
written notice that Stericycle in good faith reasonably believes the use of the
Alliance Technology or the production or sale of products using the Alliance
Technology would infringe upon the intellectual property rights of a specified
third party.

Agreement.  Thereafter, Stericycle shall not grant any Encumbrances with respect
to, or allow any Encumbrances to be placed upon, the Alliance Technology which
could adversely affect Baxter's rights under this Agreement.

    11.  SEVERABILITY.  Each section, paragraph, clause, subclause and
provision of this Agreement shall be severable from each other and, if for any
reason any section, paragraph, clause, subclause or provision is invalid or
unenforceable, such invalidity or unenforceability shall not prejudice or in any
way affect the validity or enforceability of any other section, paragraph,
clause, subclause or provision of this Agreement.  It is intended that any
section, paragraph, clause, subc1ause or provision which is invalid or
unenforceable as written be valid and enforceable to the fullest extent
possible.

Agreement would cause irreparable harm that could not be remedied by money
damages.  In the event of a breach, or threatened breach, by either party of any
provision of this Agreement, in addition to and without limitation of, any other
rights or remedies existing, under this Agreement, at law or in equity, or
otherwise, the other party shall be entitled to obtain specific performance,

         Re:  STERICYCLE, INC. V. BROWNING-FERRIS INDUSTRIES, INC. -- CASE NO.
              CV 93-1900 DT (EX)

Dear Ms. Boyle:

         In accordance with your request, I will summarize herein the nature
and status of the litigation now pending in the United States District Court in
Los Angeles, California between plaintiff Stericycle, Inc. ("Stericycle") and
defendant Browning-Ferris Industries, Inc. ("BFI").

         Plaintiff Stericycle's Complaint, filed on April 1, 1993, alleges that
defendant BFI has been engaged in an attempt to monopolize and has monopolized
the infectious medical waste management industry in the United States, and
certain geographic submarkets thereof, in violation of Section 2 of the Sherman
Act (15 U.S.C. Section 2).  Stericycle further alleges that BFI has engaged,
INTER ALIA, in the following anticompetitive conduct: 1) BFI has interfered
with, obstructed and opposed Stericycle's efforts to gain acceptance in the
marketplace and its ability to obtain permits/licenses; 2) BFI has embarked on a
"scare tactics" program consisting of a series of intentionally false and
misleading statements and misrepresentations to the public and customers
regarding Stericycle and its business operations; and 3) BFI has pursued a
below-cost and discriminatory pricing program to eliminate Stericycle as a
competitor.

         Plaintiff Stericycle also alleges that defendant BFI's false,
misleading and deceptive statements and practices

Ms. Mary Ann Boyle

constitute violations Of Section 43(a) of the Federal Lanham Act (15 U.S.C.
Section 1125(a)) and amount to trade libel.  Finally, Stericycle alleges that
BFI's predatory and anticompetitive practices establish claims for California
state law unfair competition and tortious interference with contractual
relations and prospective economic advantage.

         Plaintiff Stericycle throughout the lawsuit seeks to recover treble
its actual damages, punitive damages, costs of suit and attorneys' fees. 
Stericycle also seeks relief in the form of an injunction prohibiting BFI from
continuing its anticompetitive practices.

         On May 21, 1993, defendant BFI filed a "knee-jerk" retaliatory
counterclaim against Stericycle consisting of two purported causes of action. 
In its first claim, BFI alleges that Stericycle has violated Section 43(a) of
the Lanham Act (mimicking Stericycle's claim) by engaging in a false and
misleading advertising and promotional campaign to portray itself as an
environmentally sensitive medical waste recycler to the purported detriment of
BFI.  In its second claim, BFI alleges that Stericycle has engaged in unfair
competition in violation of Section 17203 of the California Business and
Professions Code.

         On July 26, 1993, the Court held a Mandatory Status Conference.  At
that hearing the Court set a trial date for September 14, 1994, and ordered that
all discovery be completed by June 3, 1994.  The parties are currently in the
process of exchanging documents and subpoenaing documents from third parties.

         This is an application for authority to transport biohazardous wastes
for collection or disposal in specified territory under contract with
Stericycle, Inc.  The Commission entered an order denying the application but
staying its terms and giving the principals leave to modify their relationship
and to redocket the application as one for common carriage.  The principals made
a filing within the allowed time that fell outside the terms of the order, and
the Commission entered an order lifting the stay to allow review.

         Now, on reconsideration, of the latter order, the applicant and the
shipper ask the Commission to allow the rearrangement of relationships(1) and
the redocketing(2) that the Commission previously authorized.  Commission Staff
opposes the petition.(3)

- --------------------
    (1)The applicant, now known as Ryder Dedicated Resources, Inc., (Ryder)
asks leave to withdraw.  The supporting contract shipper, now known as
Stericycle, Inc., (Stericycle) asks leave for substitution as successor, and  
addresses the issues on reconsideration.  Substitution should be allowed.

    (2)An amended application is submitted for contract carrier authority.

    (3)BFI, another carrier of biohazardous wastes within the state, admits
that it is not a party but nonetheless submits an answer.  The Commission does
not consider that document; BFI does not show that it or any predecessor in
interest has party status.  It claims an interest in the determination of
whether the proposed application should be considered new or amended.  Allowing
amendment is within the context of this proceeding and a non-party may not
participate.  A potential party's participation in a new or redocketed
application would begin only after the application is docketed and a protest is
filed.  Therefore, considering BFI's pleading would be improper.

ORDER M. V. G. NO. 1657                                                   PAGE 2


         Commission Staff's principal concern lies in the area of notice to 
affected carriers and allowing them the opportunity to participate.  The 
Commission believes that its docketing procedures afford those protections 
irrespective of whether the application is deemed new or whether it is deemed 
amended.  In either event, the amended application will be placed on the 
Commission's docket and published, so persons affected by the amendment will 
have the opportunity to protest the amended application and to participate in 
the hearing.  Counsel fears that the result of the amendment might be the 
mere substitution of names on the application; that is not the case.

         Neither succession nor redocketing is a new concept.  A carrier's
successor in interest, following a transfer proceeding, may succeed to its
predecessor's interest in pending applications.  The transfer proceeding affords
potential protestants the same opportunity to explore fitness of the transferee
that would be afforded in an amended and redocketed application.

         The Commission has also authorized redocketing of contract carrier
applications when it has appeared during the course of a proceeding that the
applicant has not applied for authority that matches the nature of the service
it wishes to perform.

         This action is neither inconsistent with the goal of finality of
proceedings nor a guarantee that authority will be granted.  As to the former,
the parties appear to agree that an application will be presented and litigated
no matter what the form -- i.e., whether the application is redocketed or newly
docketed.  In the Commission's judgment, in this proceeding, it is preferable
that the initial application be redocketed.  Relevant factors include the
principals' apparent good faith belief that Ryder's original applications for
temporary and permanent authority were consistent with law, the findings of the
initial and final orders regarding public support and need for the proposed
service, Stericycle's decision to enter the market based on market conditions at
a point in the past, and the principals' apparent good faith belief that their
submission complied with the terms of the Commission's January order.  The
Commission will base its decision upon the entire record when remaining phases
of the application process are concluded.

         The Commission generally limits reconsideration to errors of law in an
order or to matters of fact that are newly discovered that were not within the
petitioner's responsibility to know at the time of the initial proceeding. 
Here, no party challenges reconsideration for the purposes sought.  Now that an
application is submitted that appears on its face to fall within

parameters contemplated in the Commission's January order, the Commission sees
no overriding reason to reject it on procedural grounds.  Instead, granting
reconsideration and accepting the amended application have the potential to
reduce the scope of litigation and to simplify the proceeding without abridging
the parties' rights to explore and to challenge the amended application. 
Redocketing will also allow participation by parties who did not protest the
initial application.  The Commission's approach appears to be that which is most
consistent with the public interest.


         For the reasons stated in this Order, the Commission grants
reconsideration and orders that the amended application, reflecting Stericycle's
succession as applicant and the change from contract to common carriage, be
redocketed forthwith to allow protests by persons who did not protest the
initial application based on the identity of the applicant or the nature of the
transportation.  The stay of the January 25, 1993 Order should be extended to
permit resolution of any issues relating to the amended application.

                                      O R D E R

         THE COMMISSION grants reconsideration of its Order of July 26, 1993,
accepts the amended application in which Stericycle proposes to succeed to
Ryder's interest in the application and to amend it to seek common carrier
authority, and orders that the application be redocketed for protest and such
further proceedings may be required.

         IN SO DOING, The Commission extends the stay imposed in its January
25, 1993 Order, pending resolution of any issues relating to the amended
application.

                       EFFECT OF SEPTEMBER 16, 1993 WUTC ORDER
                            ON STERICYCLE/RYDER OPERATIONS

1.  The new Order grants Stericycle of Washington's petition for
reconsideration of the Commission's July 26 Order.  The new Order:

    (a) substitutes Stericycle for Ryder for purposes of further proceedings on
the application for permanent authority originally initiated by Ryder;

    (b) allows Stericycle to convert the application for permanent authority
from an application for contract carrier authority to an application for common
carrier authority;

    (c) stays indefinitely the Commission's Order of January 25, 1993, denying
Ryder's application for permanent authority; and

    (d) permits Ryder to continue providing service to Stericycle, Inc. and its
customers under the temporary authority granted to Ryder in late 1991 at the
startup of Stericycle operations.

2.  The new Order requires the original Ryder permanent application to be
redocketed in Stericycle's name and as amended.  A new notice must be given to
interested parties and additional protests must be accepted based on this new
notice.  Further proceedings on the redocketed application will be required in
many respects like those required for a new application.  The extent of those
proceedings and who may participate in them will be matters resolved in the
first instance by the hearing officer to whom the redocketed case is assigned.

3.  Stericycle of Washington will take over all regulated transportation
functions now performed by Ryder when and if permanent common carrier authority
is granted.  In the interim, Ryder may continue to serve Stericycle, Inc. and
Stericycle customers.

4.  The continuing validity of the Ryder temporary authority is the subject of
proceedings now pending in the Washington Court of Appeals.  Oral argument
should be scheduled in this case sometime between April 1 and September 30,
1994.  A decision by the Court can be expected any time within a year after oral
argument.  We believe that it is probable that Stericycle will prevail before
the Court of Appeals.  However, it is possible that the Ryder TA could be
invalidated by the Court of Appeals before the Commission has completed action
on Stericycle's application for permanent authority.  Other legal challenges to
the Ryder TA are possible, based on recent actions by the Commission.

    RE:  LITIGATION PENDING IN WASHINGTON STATE

Dear Mary Ann:

    Pursuant to your request, this letter will describe the litigation pending
in Washington state to which Stericycle, Inc. is a party and for which our firm
has been responsible.

    The only such case is WASHINGTON WASTE MANAGEMENT ASSOCIATION, ET AL. V.
WASHINGTON UTILITIES AND TRANSPORTATION COMMISSION, ET AL., Superior Court for
the State of Washington/Thurston County, Cause No. 92-2-00300-4, involving the
unique Washington legal and regulatory scheme governing the collection and
transportation of solid waste, including medical waste.  This case is an
outgrowth of proceedings before the Washington Utilities and Transportation
Commission (WUTC), which must grant operating authority to any company which
wishes to engage in regulated solid waste collection and transportation in
Washington.  In proceedings before the WUTC, Ryder Distribution Resources sought
temporary authority to operate as a contract carrier of medical waste under
contract with Stericycle, Inc.  The WUTC granted temporary operating authority
to Ryder in December 1991 (reaffirmed in January 1992), pending action on
Ryder's related application for permanent operating authority.  Competitors of
the Ryder/Stericycle sought judicial review of the WUTC's grant of temporary
authority to Ryder by filing petitions for review with the Thurston County
Superior Court, arguing (among other things) that Stericycle was acting as a
common carrier and should be required to obtain common carrier operating
authority and submit to regulation by the WUTC.  Ryder immediately intervened in
that action.

<PAGE>

Ms. Mary Ann Boyle

    On October 29, 1992, the Superior Court issued a Letter Opinion holding
that the WUTC's grant of temporary authority to Ryder was invalid.  Shortly
thereafter, Stericycle, Inc. filed motions to intervene, for stay and for
reconsideration.  On November 20, 1992, the Superior Court entered an order
permitting Stericycle to intervene and a Final Order finalizing the decision
announced in the Letter Opinion.  The Court also entered an order staying its
Final Order pending a hearing on motions for reconsideration filed by Stericycle
and Ryder.  On December 21, 1992, the Superior Court denied the motions for
reconsideration but granted a further stay of its Final Order until February 1,
1993.

    Ryder and Stericycle appealed the decision of the Superior Court to the
Washington Court of Appeals, Division II, and immediately sought a stay of the
Superior Court's decision from the Court of Appeals.  By order dated January 29,
1993, the Court of Appeals granted a stay of the Superior Court's Final Order
pending resolution of the appeal or a final decision of the WUTC on Ryder's
application for permanent operating authority, whichever might first occur.

    The appeal is still pending before the Court of Appeals.

    On January 25, 1993, the WUTC issued a final decision (Order M.V.G. No.
1596) finding that there was a need for the Stericycle/Ryder service and that
existing carriers did not provide equivalent service, but denying Ryder's
application for permanent contract carrier authority.  In its order, the
Commission suggested that Stericycle and/or Ryder were operating as common
carriers and should reformat their joint service as common carrier service.  The
Commission then stayed that action to permit reorganization of the
Stericycle/Ryder service to meet the Commission's requirements.  That stay
continued in effect until July 26, 1993, when the WUTC served a subsequent order
(Order M.V.G. No. 1646) rejecting a reorganized operating format proposed by
Stericycle and Ryder and terminating the stay.

    The Stericycle service continues under Ryder's temporary authority pending
expiration of a 30-day "grace period" informally allowed by the WUTC prior to
the enforcement of its orders.  Stericycle and Ryder have filed petitions for
reconsideration, asking that the Commission's stay of its January 25, 1993 order
be reinstated pending further efforts by Stericycle to reorganize its business
to meet the Commission's requirements.  Those petitions are pending.

    The status of the stay of the Superior Court's order granted by the Court
of Appeals is unclear.  To date, the parties have treated the Commission's stay
of its January 25 order as continuing in effect for the 30-day "grace period"
which began on or about July 26, 1993.  It is possible that this "grace period"
will be extended by the filing of the petitions for reconsideration.

    On August 3, 1993, Stericycle of Washington, Inc., a wholly owned
subsidiary of Stericycle, Inc., filed an application for permanent authority to
operate as a common carrier of medical waste, serving the Stericycle medical
waste treatment facility in Morton, Washington.  Final Commission action on this
application could take up to a year or more.

    On August 10, 1993, Stericycle of Washington, Inc. filed an application for
temporary common carrier authority pending final Commission action on its
application for permanent authority.  Final Commission action on Stericycle of
Washington's application for temporary authority should be completed within 40
days.  We believe that the common carrier operations proposed by Stericycle of
Washington will probably satisfy the Commission's requirements.

    If the WUTC grants reconsideration of its July 26, 1993 Order and
reinstates the stay or seeks comments on these requests from interested parties,
the status quo should continue at least pending final Commission action on
Stericycle of Washington's application for temporary operating authority.  If
the Commission denies reconsideration, we will argue that there should be a new
30-day "grace period" from that date.

    Nevertheless, a gap could arise between the termination of the "grace
period" for the July 26 order and Commission action on Stericycle's application
for temporary authority.  In that event, Stericycle would have several options,
including temporarily transporting its customers' waste to treatment facilities
outside the state or attempting private carriage.  However, we are optimistic
that Stericycle of Washington's application for temporary common carrier
authority will be granted before Ryder's existing temporary authority is finally
invalidated, so that these options need not be tested.

    Please let me know whether you need any additional information.

3.  The Illinois Institute of Technology Research Institute ("IITRI") has
    claimed, in letters to Stericycle, all rights to the radio frequency heat
    tunnel technology (the "RF Technology") formerly used by Stericycle in
    processing medical waste.  On May 5, 1989, Stericycle signed a license and
    royalty agreement (the "Royalty Agreement") with IITRI granting Stericycle
    rights to commercially apply the RF Technology to the field of medical
    waste treatment.  The Royalty Agreement may require IITRI and Stericycle to
    determine a royalty rate to be paid by Stericycle on each pound of medical
    waste processed by Stericycle using the RF Technology.  The parties have
    not successfully negotiated such a rate and no negotiations have taken
    place for over a year.  Stericycle believes it has made adequate reserves
    in its financial statements for any royalty that may be due IITRI. 
    Stericycle no longer uses the RF Technology in its business.

schedule may be amended from time to time.

              (1)  TITLE TO THE EQUIPMENT.  Stericycle shall retain title to
the Equipment; provided, however, that if this Agreement is terminated for any
reason, Stericycle agrees to pay Sage an amount equal to [         *           ]
the "fair market value" of the Equipment.  For purposes of this Agreement, "fair
market value" will be determined by an independent appraiser jointly selected by
Sage and Stericycle.  The appraiser shall take into consideration the value of
the Equipment as operated "in place".  In the event that Sage does not agree
with the appraised value, Sage shall, within thirty (30) days of delivery of the
appraisal, have the option to meet the appraisal price and purchase the
Equipment (the "Option Period"). The ultimate purchaser of the Equipment shall
make payment to the other party within fifteen (15) days after the expiration of
the Option Period.

              (2)  RELATED COSTS.  Stericycle shall pay all maintenance and
insurance costs, and all taxes, that pertain to the Equipment.  For purposes of
paragraph 2.E.(1) of this Agreement, the maintenance and insurance costs and the
taxes pertaining to the Equipment shall be included as part of the direct
operating cost of producing the Product by application of the Process.

         B.   PROJECT MANAGEMENT.  Stericycle shall be responsible for
purchasing the Equipment.  Stericycle shall also be responsible for managing and
supervising the operations which are undertaken pursuant to completion of
development of the Process.

              (1)  MANAGEMENT FEE.  In consideration of its management and
supervision of the operations which are necessary to completion of development
of the Process, Sage agrees to pay Stericycle a fee of [       *         ]

              (2)  ADDITIONAL COSTS.  If Sage and Stericycle agree that
additional developmental expenses are required with respect to the Process, they
will share such expenses equally.

    2.   PURCHASE AND SALE.  From and after the time that development of the
Process is complete, Sage agrees to purchase from Stericycle the Product that is
reclaimed by application of the Process, and Stericycle agrees to sell to Sage
the Product that is reclaimed by application of the Process, upon the following
terms and conditions.

         A.   DESCRIPTION OF GOODS.  The Product is a plastic product
consisting substantially of polypropylene with traces of polyethylene and
polystyrene and other olefins.  Stericycle expressly agrees and acknowledges
that Sage may use and incorporate the Product into any of its products, unless
Sage has agreed to the sale of Product pursuant to paragraph 2.C.(3) herein, and
Stericycle has entered into an exclusive agreement with a purchaser for the
sale of that Product.

         B.   EXCLUSIVE PURCHASER.  Except as otherwise provided herein,
Stericycle represents that it will not sell, give away, or deliver to any other
person, firm or corporation any commercial amount of the Product reclaimed by it
during the term of this Agreement pursuant to the application of the Process
without Sage's prior written consent, which consent shall not unreasonably be
withheld.


* Omitted; filed separately with the Commission

<PAGE>

If at anytime after December 31, 1994, Sage's annual purchases fall below [
   *      ] per year, Sage agrees to change its rights to a non-exclusive basis.

         C.   INITIAL GUARANTEED PURCHASE.  Stericycle shall sell and deliver
to Sage, and Sage shall purchase and accept from Stericycle, a minimum of [
     *         ] of Product per month ("Minimum"), commencing [    *      ], and
for each month thereafter through [    *      ].

              (1) SUBSEQUENT PURCHASES.  After [           *               ],
Sage shall update and amend, on a quarterly basis, its estimate of its
requirements of the Product for the following twelve (12) month period.  The
amount required shall be based solely on Sage's determination of its needs.  The
actual quantity of Product purchased by Sage shall be reflected in a purchase
order (the "Purchase Order") . A Purchase Order shall be placed on the first day
of the month for delivery by the fifteenth (15th) day of the succeeding month.

              (2)  FAILURE TO MEET REQUIREMENTS.  If, for any reason,
Stericycle does not completely fill a Purchase Order, and if the Purchase order
is for an amount of Product which is less than the maximum amount of Product
which can be reclaimed by the Process [          *               ], Stericycle
shall have sixty (60) days within which to make up the amount by which the
Purchase Order is deficient; provided, however, that if the amount of Product
enumerated in a Purchase Order exceeds the amount of Product enumerated in the
immediately preceding Purchase Order by fifty percent (50%) or more, Stericycle
shall have one hundred twenty (120) days within which to


* Omitted; filed separately with the Commission


                                          5

<PAGE>

make up the amount by which the Purchase Order is deficient. If, within that
sixty (60) day period or one hundred twenty (120) day period, as the case may
be, Stericycle is unable to make up the amount of the deficiency, Sage shall
have the right to develop a source of Product which is adequate to meet its
requirements; in the alternative, Sage may purchase the Product, or such other
product as it deems suitable, from a third party.

              (3)  SALES TO THIRD PARTIES. If the amount of Product reclaimed
by Stericycle is in excess of the amount required by Sage, Stericycle shall have
the right to sell the excess to a third party; provided, however, that (a)
Stericycle shall not sell such excess to any other person, firm or corporation
which makes products which are made by Sage and in which Sage incorporates the
Product and (b) Stericycle shall not sell such excess to any other person, firm
or corporation which is engaged, directly or indirectly, in the development,
manufacture or marketing of products which compete with the products which are
developed, manufactured and marketed by Sage without Sage's prior written
consent, which consent shall not unreasonably be withheld; provided further,
that no sales shall be made at a price less than Sage's total unit cost without
Sage's prior approval, which approval shall not unreasonably be withheld.

    D.   QUALITY OF GOODS. The units of Product which are produced by
Stericycle and which comprise a Purchase Order shall meet the quality standards
which are specified in Exhibit "B" attached hereto and incorporated herein.
Stericycle warrants that the Product will conform to the attached specifications
and that it will convey


                                          6

<PAGE>

good title thereto.  The Product shall not include (and Sage shall not accept)
"Excluded Material" (a) anatomical waste; (b) hazardous waste or hazardous
substances, as defined under the Resource Conservation and Recovery Act of 1976,
the Comprehensive Environmental Response, Compensation and Liability Act of
1980; or (c) radioactive materials, as defined by the United States Nuclear
Regulatory Commission.  Sage will not accept Excluded Material, and if
Stericycle delivers Excluded Material to Sage, Sage may reject such Excluded
Material and any Product which contains such material.  At Sage's option, it may
forward such Excluded Material for disposal at Stericycle's sole risk and
expense.  In order that Stericycle may produce Product which satisfies Sage's
quality assurance standards, Sage agrees to assist Stericycle in understanding
and satisfying those quality assurance standards of Sage which may be unique to
its needs.  Any units of the Product which do not reasonably satisfy the
foregoing quality assurance standards may be rejected by Sage pursuant to the
terms of paragraph 4 below.

         E.   PURCHASE PRICE.  The total purchase price for a Purchase Order
shall be equal to [
                                *

           ], as those costs are hereinafter defined (the "Purchase Price").
The direct and incremental costs of the Product shall be determined as follows.


* Omitted; filed separately with the Commission


                                          7

<PAGE>

              (1)  DIRECT COSTS.  For purposes of this Agreement, direct cost
shall include direct production and transportation expenditures which are
associated with the production and delivery of the Product to Sage.

              (2)  RELATED PARTY ALLOCATIONS.  Additional charges will be
allocated for facility usage and nonproduction equipment.  All such allocations
shall be agreed to by Sage prior to billing for such costs.

              (3)  INCREMENTAL COSTS.  Sage and Stericycle agree that the
incremental costs for reclaiming the polyolefin plastics shall be equal to [
          *                 ].  The incremental costs associated with the
Product include the cost of additional energy usage for processing, additional
material handling requirements before and after treatment and adjustments to
normal processing standards for sharps-only materials.

              (4)  QUARTERLY AND YEAR-END ADJUSTMENT.  Monthly charges shall be
computed on a pro forma cost-per-pound basis as agreed to by the parties.  An
accounting which reflects the cost set forth herein on a per pound basis shall
be provided on a quarterly basis, and Sage shall pay or be credited with the
difference between the per pound cost as determined by the accounting and the
per pound cost as determined by the pro forma.  At the end of each calendar
year, a comprehensive accounting which reflects the annualized cost per pound
for the entire year shall be provided, and Sage shall pay or be credited with
the difference between the actual costs, as computed in accordance with the
terms of this Agreement, for the


* Omitted; filed separately with the Commission


                                          8

<PAGE>

calendar year and the sum total of payments and credits for that year.  Any
disputes with respect to the accounting shall be resolved within ninety (90)
days after the presentation of the accounting, and if the parties cannot resolve
the dispute within that time period, they shall submit the matter to a certified
public accounting firm which is acceptable to both of them.  Within sixty (60)
days thereafter, the accounting firm to which the matter is submitted shall
render a decision, and the decision so rendered shall be binding upon the
parties.

              (5)  PAYMENT OF PURCHASE PRICE.  Sage shall pay the Purchase
Price for each shipment of Product and adjustments within fifteen (15) business
days after delivery.

    3.   DELIVERY OF GOODS.

         A.   PLACE FOR DELIVERY. Stericycle shall deliver all units of Product
comprising a Purchase Order FOB at Sage's facility located in Crystal Lake,
Illinois.

         B.   TIME FOR DELIVERY. Stericycle shall commence delivery by [     *
   ], and shall deliver all other Purchase Orders to Sage by the fifteenth
(15th) day of each succeeding month (hereinafter referred to, singly, as the
"Purchase Order Period" and, collectively, as the "Purchase Order Periods")
until this Agreement terminates or is otherwise canceled.

    4.   RIGHT TO INSPECT GOODS.  Before delivery of any shipment of Product is
considered complete under this Agreement, Sage shall have the right to inspect
the Product tendered for delivery.  Such inspection shall take place at Sage's
facility in Crystal Lake, Illinois.  If any portion of a particular Purchase
Order does not satisfy Buyer's quality assurance standards, Buyer may, within
five (5) business days after taking delivery, reject that portion and
immediately return it to Stericycle freight collect.  Stericycle shall also pay
the shipping costs associated with the furnishing of replacement goods.  Sage
shall not be charged for those portions which are properly rejected as being
nonconforming.  After five (5) business days from delivery of a shipment, all
Product is deemed inspected and accepted by Sage.

    5.   ROYALTY.  Sage shall pay a royalty to Stericycle based on Sage's "Net
Sales" of those products which it has manufactured and which incorporate the
Product.  For purposes of this Agreement, "Net Sales" shall be defined as the
total monthly invoice price of those products sold by Sage which incorporate the
Product, less sales or excise taxes and shipping costs actually paid, directly
or indirectly, by Sage, and less actual trade discounts, rebates and returns and
allowances thereon.  The amount of the royalty shall be equal to Sage's Net
Sales of such products multiplied by a royalty percentage determined in
accordance with the following schedule:


                                          10

2. [       *       ]                 [       *         ]
3. [       *       ]                 [       *         ]
4. [       *       ]                 [       *         ]

The royalty so computed shall be paid to Stericycle on a quarterly basis, within
thirty (30) days after the end of the calendar quarter.

    6.   TERM.  Subject to the terms of paragraph 7 herein, the term
of this Agreement shall commence as of [      *          ] and terminate on [
    *       ] (the "Initial Term").  Thereafter, this Agreement shall be
automatically extended for successive one (1) year terms unless sooner
terminated pursuant to the terms of paragraph 7 herein.

    7.   TERMINATION.

         A.   TERMINATION DURING THE INITIAL TERM.  During the Initial Term,
this Agreement may be terminated for any of the following reasons:

              (1)  At Sage's option, if Stericycle is unable to deliver the
full amount of a Purchase Order to Sage within its attendant Purchase Order
Period, and, within sixty (60) days after written notice, Stericycle fails to
cure the amount of the deficiency;

<PAGE>

              (2)  At Sage's option, if four (4) shipments of Product in a
twelve (12) month period fail to satisfy Sage's quality assurance standards, as
those standards are delineated on Exhibit "B" attached hereto and incorporated
herein;

              (3)  At Stericycle's option, if Sage fails to pay the Purchase
Price to Stericycle, provided that Stericycle has given written notice to Sage
and Sage has failed to cure within sixty (60) days thereafter; and

              (4)  At Stericycle's option, if Sage fails to pay the royalty
provided for in paragraph 5 herein to Stericycle, provided that Stericycle has
given written notice to Sage and Sage has failed to cure within sixty (60) days
thereafter.

              (5)  By either party, if the other party files a petition in
bankruptcy, has a receiver appointed for it, becomes insolvent or is unable to
meet its debts as they come due.  In the event that Sage terminates this
Agreement pursuant to the terms of this paragraph, it shall have an option to
purchase the Equipment from Stericycle for its net book value at the time of
termination pursuant to the terms set forth in paragraph 1.A.(1) of this
Agreement.

              (6)  At Sage's option, if Sage demonstrates the commercial
availability of product which is substantially similar to the Product and which
has a price which is [          *              ] than the average weighted cost
of the Product for the prior six (6) months.

Initial Term, this Agreement may be terminated for any of the following reasons:

              (1)  Sage or Stericycle may terminate this Agreement at the end
of any given year upon not less than 365 days written notice delivered to the
other party; and

              (2)  For any of the reasons enumerated in paragraphs 7.A.(1)-
7.A.(6) of this Agreement.

    8.   AUDIT.

         A.   AUDIT BY STERICYCLE.  Stericycle shall have the right, upon
written request, to inspect Sage's books and records in order to verify Sage's
accounting for the royalty which is payable pursuant to paragraph 5 herein;
provided, however, that Stericycle shall conduct no more than two (2) such
inspections in any twelve (12) month period.  Any inspection shall take place
during normal business hours, upon reasonable notice, at Sage's address set
forth below.

         B.   AUDIT BY SAGE.  Sage shall have the right, upon written request,
to inspect Stericycle's books and records in order to verify Stericycle's
accounting for the all costs of the Product, as those costs are described in
paragraph 2.E herein; provided, however, that Sage shall conduct no more than
two (2) such inspections in any twelve (12) month period.  Any inspection shall
take place during normal business hours, upon reasonable notice, at Stericycle's

<PAGE>

         C.   Any disputes with respect to the accounting shall be resolved
within ninety (90) days after the presentation of the accounting, and if the
parties cannot resolve the dispute within that time period, they shall submit
the matter to a certified public accounting firm which is acceptable to both of
them.  Within sixty (60) days thereafter, the accounting firm to which the
matter is submitted shall render a decision, and the decision so rendered shall
be binding upon the parties.

    9.   JOINT OWNERSHIP OF TECHNOLOGY.

         A.   JOINTLY DEVELOPED TECHNOLOGY.  Any and all patents, processes,
technologies, drawings, technical information and data, and other information
and intangible property rights which are developed under and pursuant to the
terms of this Agreement shall be the joint property of Sage and Stericycle (the
"Technology") . The Technology shall be described on Schedule "C" attached
hereto, which schedule may be amended from time to time.  Both Sage and
Stericycle agree that each party shall have the perpetual right to use the
Technology directly or to sublicense the Technology; provided, however, that
neither party shall have the right to use the Technology to create products
which would compete with the products which have been created by the other
party.  Sage and Stericycle recognize that Baxter and Stericycle have entered
into an agreement to explore development of separate Baxter-Stericycle
Technology in which Sage will have no rights; provided, however, that the
Baxter-Stericycle agreement shall not limit any rights that Sage has under this
Agreement.


                                          14

<PAGE>

         B.   PRE-EXISTING TECHNOLOGY.  Any pre-existing patents, processes,
technologies, technical information and data, and any other information and
intangible property rights, (collectively, the "Preexisting Technology") shall
remain the exclusive property of Sage or Stericycle, as the case may be, and
neither party shall have the right to restrict the other party's use of its
Preexisting Technology.

    10.  NATURE OF RELATIONSHIP.  While this Agreement contemplates that Sage
and Stericycle will work together to pursue certain enumerated goals, Sage and
Stericycle expressly agree that this Agreement shall not create a joint venture
for tax purposes and that each party shall determine the tax consequences of its
actions under and pursuant to the terms of this Agreement on an independent
basis.  Sage and Stericycle also expressly agree that nothing contained in this
Agreement shall be construed to authorize either party to act as general agent
for the other party or to obligate the other party to pay any liability or take
any action other than those set forth herein or those expressly agreed to by the
parties in the future.

    11.  INDEMNITY.

    A.   INDEMNITY BY STERICYCLE.  Stericycle agrees to indemnify and hold Sage
harmless from and against any and all liabilities, obligations, suits, actions,
proceedings or claims asserted against Sage which arise out of or result from
the negligent


                                          15

<PAGE>

acts or omissions of Stericycle with respect to the design or manufacture of the
Product or the handling of the Product prior to its delivery to Sage.

         B.   INDEMNITY BY SAGE.  Sage agrees to indemnify and hold Stericycle
harmless from and against any and all liabilities, obligations, suits, actions,
proceedings or claims asserted against Stericycle arising out of or resulting
from the negligent acts or omissions of Sage with respect to the design or
manufacture of any of its products which incorporate the Product, or the
handling of the Product subsequent to its delivery to Sage.

    12.  CONFIDENTIALITY.  Sage and Stericycle acknowledge and agree that,
during the term of this Agreement, either of them may receive or otherwise
acquire information which is confidential or proprietary in nature and which is
the exclusive property of the other party.  Accordingly, Sage and Stericycle
agree that, during the term of this Agreement, and from and after the date of
its termination, they will not disclose or use, directly or indirectly, any such
confidential or proprietary information unless they receive written
authorization from the other party.  Such confidential or proprietary
information shall include, but shall not be limited to technical and
non-technical data, formulae, patterns, compilations, programs, devices,

<PAGE>

    13.  AUTHORITY. Sage and Stericycle each have full authority to enter into
this Agreement.  Neither Sage nor Stericycle has entered into nor will either of
them enter into any agreement which would prohibit that party from meeting its
full obligations under this Agreement.

    14.  GOVERNING LAW. This Agreement shall be subject to, and governed by,
the laws of the State of Illinois, including the Illinois Trade Secrets Act,
765 ILCS 1065/5 ET. SEQ. (1992 State Bar Edition) .

ARTICLE IV.  RENT.
- ------------------

4.1    BASE RENT.  Tenant covenants to pay without notice, deduction, set-off
or abatement to Landlord the Base Rent in lawful money of the United States in
equal consecutive monthly installments in advance on the first day of each month
during the Lease Term.  Base Rent for any partial month shall be prorated on a
per diem basis.  Base Rent shall be payable to Landlord at Landlord's Address or
such other place as Landlord may designate from time to time in writing.  Tenant
shall pay the first full month's Base Rent within seven (7) days of execution of
this Lease.

4.2    ADDITIONAL RENT.  Tenant covenants to pay without notice, deduction,
set-off or abatement to Landlord the Additional Rent in lawful money of the
United States in equal consecutive monthly installments in advance on the first
day of each month during the Lease Term.  Additional Rent for any partial month
shall be prorated on a per diem basis.  Additional Rent shall be payable to
Landlord at Landlord's Address or such other place as Landlord may designate in
writing.  In order to provide for current payments of Additional Rent, Tenant
agrees to pay an amount of Additional Rent reasonably estimated by Landlord from
time to time commencing on the first day of the month following the month in
which Landlord notifies Tenant of the amount of such Additional Rent.  If, as
finally determined, the amount of Additional Rent owing by Tenant shall be
greater than or less than the aggregate of all installments so paid to Landlord
for each calendar year, the Tenant shall pay to Landlord the amount of such
underpayment, or Landlord shall credit Tenant for the amount of such
overpayment, as the case may be.  It is the intention hereunder to estimate the
amount of Additional Rent for each calendar year and then to adjust such
estimate in the following year based on the actual amount of Additional Rent
owing.  The obligation of Tenant with respect to the payment of Additional Rent
shall survive the termination of this Lease.  Any payment, refund or credit made
pursuant to this paragraph shall be made without prejudice to any right of
Tenant to dispute the amount of Additional Rent owing, or the right of the
Landlord to correct any items as billed pursuant to the provisions hereof.
Within 30 days of the date Landlord notifies Tenant of the amount of Additional
Rent owing, Tenant or its authorized agent shall have the right to inspect the
books of Landlord during the business hours of Landlord at such location that
Landlord may specify, for the purpose of verifying such amount.  Unless Tenant
asserts specific errors within such 30 days, such notification by Landlord shall
be deemed to be correct.  No decrease in Additional Rent shall reduce Tenant's
liability hereunder below the amount of Base Rent payable hereunder.

    4.2(a)    UTILITIES AND SERVICES.  Landlord shall not be liable for any
    interruption or failure whatsoever in utility services.  Tenant shall
    contract in its own name and pay for all charges for electricity, gas,
    fuel, telephone, and any other services or utilities used in, servicing or
    assessed against the Premises, unless otherwise herein expressly provided.
    Additionally, and if the Building is master metered for water, sewer and
    exterior lighting, Tenant agrees to pay to Landlord as Additional Rent
    Tenant's Prorata Share of the cost of such utilities for the Building.
    Additionally, and as containerized rubbish collection bins will be provided
    to the Building, Tenant agrees to pay to Landlord as Additional Rent,
    Tenant's reasonable Allocated Share of the service cost of such bins
    (unless Landlord, exercising reasonable discretion, should determine that
    Tenant's actual use thereof is greater than such Tenant's Allocated Share
    therefore, in which case an equitable adjustment shall be made).  Landlord
    may, however, require Tenant or Tenant may desire to contract for

                                      3

     his own rubbish collection, in the event Tenant's needs for such 
     containers constitute excessive demand on common containers. In such 
     event, Tenant shall contract with the same provider as the Center's 
     common bins.

     4.2(b)    INSURANCE.     Tenant shall pay to Landlord as Additional Rent
     Tenant's Reasonable Prorata Share (or, Tenant's Proportionate Share in the
     event there is more than one Building in the Center) of the cost of the
     premiums for the fire and extended coverage insurance that Landlord
     maintains for the Center.

     4.2(c)    REAL ESTATE TAXES.  Tenant shall pay to Landlord as Additional
     Rent Tenant's Reasonable Prorata Share (or, Tenant's Proportionate Share in
     the event there is more than one Building in the Center) of Real Estate
     Taxes levied against the Center. "Real Estate Taxes" shall mean: (a) all ad
     valorem Real Estate Taxes on the Center (adjusted after protest or
     litigation, if any) for any part of the term of this Lease, exclusive of
     penalties; (b) any taxes which shall be levied in lieu of any such ad
     valorem Real Estate Taxes; (c) any special assessments for benefits on or
     to the Center paid in annual installments by Landlord; (e) any private
     subdivision assessment made against the Center.

     If the Lease Term shall end during a tax year ("tax year" shall mean the
     annual period for which Real Estate Taxes are assessed and levied) of which
     only part is included in the Lease Term, the amount of such Additional Rent
     shall be prorated on a per diem basis and shall be paid on or before the
     last day of the Lease Term. If the Lease Term ends in any tax year before
     the amount to be payable by Tenant has been determined under the provisions
     of this Section, an amount payable for the portion of the Lease Term during
     the tax year shall be reasonably estimated by Landlord and the estimated
     amount shall be promptly paid by Tenant. As soon as the amount properly
     payable by Tenant for the partial period has finally been determined, the
     amount shall be adjusted between Landlord and Tenant. Tenant shall be
     liable for all taxes levied against personal property and trade fixtures
     placed by Tenant in the Premises.

     4.2(d)    HVAC MAINTENANCE.   Tenant shall pay to Landlord as Additional
     Rent Tenant's Allocated Share of Landlord's cost and expense of the

     expenses incurred to repair the heating, ventilating and air conditioning
     equipment servicing the Premises.

     4.2(e)    COMMON AREA EXPENSES.    Tenant will pay to Landlord as
     Additional Rent Tenant's Prorata Share (or, Tenant's Proportionate Share in
     the event there is more than one Building in the Center) of the Common Area
     Operating Cost.

     "Common Area Operating Cost" means the Landlord's total cost and expense
     reasonably incurred in, operating, maintaining and repairing the Common
     Area, including but without limitation by enumeration, costs for all
     electricity, gas, water, sewer or fuel used in connection with the

     all electricity furnished to the Common Area to light the parking lots or
     for any other purpose; the amount paid for

     of machinery and equipment purchased or leased by Landlord to perform its
     Common Area maintenance obligations; and property management fees not to
     exceed five percent (5%) of the gross income of the Center. To the extent
     that Landlord elects to provide services which are not separately metered
     or directly billed to the tenant, such as water, sewer and trash hauling,
     the costs of such services shall be included in Common Area Operating Cost.
     Common Area Operating Cost shall not, however, include interest on debt,
     capital retirement of debt, depreciation, income taxes costs properly
     chargeable to the capital account, except for capital expenditures which
     reduce other operating expenses or such capital expenditures that are
     required by changes in any governmental law or regulation in which case
     such expenditures, plus interest on the unamortized principal investment at
     ten (10%) percent per annum, shall be amortized over the life of the
     improvements, and such costs shall be directly chargeable by the Landlord
     to Tenant in the Tenant's Prorata Share (or, Tenant's Proportionate Share
     in the event there is more than one Building in the Center).
     
     4.2(f)    RENT ON SALES TAXES.     Tenant shall pay to Landlord as
     Additional Rent any Sales or Rent Taxes, excluding any income tax, however
     named or designated, levied on any form of Rent or Additional Rent.

in the amount of five (5%) percent of such payment, without notice.

4.4  SECURITY DEPOSIT.   Tenant herewith deposits with Landlord the Security
Deposit as security for the performance by Tenant of every material covenant and
condition of this Lease.  Said Security Deposit may be mingled with other funds
of Landlord and shall bear no interest.  If Tenant shall default with respect to
any covenant or condition of this Lease, Landlord may apply the whole or any
part of such Security Deposit to the payment of any sum in default, including
Rent and Additional Rent, or any sum which Landlord may be required to spend by
reason of Tenant's default.  This includes, but is not limited to, applying the
Security Deposit first to any restoration, relamping, repairs and/or cleanup
costs necessary over and above normal wear and tear of the vacated space. 
Should Landlord so apply the Security Deposit or any portion thereof during the
Lease Term, Tenant shall promptly reimburse Landlord for same.  It is understood
that the Security Deposit is not to be considered as the last month's rent. 
Should Tenant comply with all of the covenants and conditions of this Lease, the
Security Deposit or any balance thereof shall be returned to Tenant within 30
days of the expiration of the Lease Term.

of exercising any or all of the rights hereby reserved without being deemed

Landlord and, thereupon, Landlord shall, within thirty (30) days of receipt 
of such notice, have the right to unilaterally terminate this Lease or to 
approve said subletting by written notice to Tenant.  If no notice is given 
by Landlord, Landlord will be deemed to have elected to approve the 
assignment or subletting.  If the assignment or subletting is approved and 
rents under the sublease are greater than the rents provided for herein, then 
Landlord shall have the further option either (a) to convert the sublease 
into a prime Lease and receive all of the rents, in which case Tenant will be 
relieved of further liability hereunder and under the proposed sublease, or 
(b) to require Tenant to remain liable under this Lease, in which event 
Tenant shall be entitled to retain such excess rents. If the assignment or 
subletting is approved and rents under the sublease are less than the rents 
provided herein, Tenant shall remain liable under all the covenants and 
conditions of this Lease.  Landlord may withhold its consent to any proposed 
assignee or subtenant which in Landlord's judgement (a) would conflict with 
the tenancy, use or business of any other tenant or the tenant mix of the 
Center, (b) has a net worth and/or credit history inferior to that of Tenant, 
or (c) is currently a tenant or negotiating for space in the Center.  
Landlord and Tenant shall work towards an orderly transition in the case of 
an acceptable Assignment.

6.4  LOCKS.    No additional locks or similar devices shall be attached to 
any door or window without Landlord's prior written consent.  No keys for any 
door other than those provided by the Landlord shall be made.  If more than 
two keys for one lock are desired, the Landlord will provide the same upon 
payment by the Tenant.  All keys must be returned to Landlord at the 
expiration or termination of the lease.

6.5  MAINTENANCE BY TENANT.   Tenant shall be responsible for all maintenance 
and repair to the Premises of whatsoever kind or nature that is not herein 
set forth specifically as the obligation of Landlord.  Tenant shall take good 
care of the Premises and fixtures, and keep them in good repair free from 
filth, overloading, danger of fire or any pest or nuisance, repair any damage 
or breakage done by Tenant or Tenant's agents, employees or invitees, 
including damage done to the Building/s by Tenant's equipment or 
installations. Tenant shall be responsible for the repair and replacement of 
all glass and plate glass on the Premises.  In the event Tenant fails to 
maintain the Premises as provided for herein Landlord shall have the right, 
but not the obligation, to perform such maintenance as is required of Tenant 
in which event Tenant shall reimburse Landlord for its costs in providing 
such maintenance or repairs together with a ten (10%) percent charge for 
Landlord's overhead and Tenant shall promptly reimburse Landlord for the 
amount so billed to Tenant by Landlord.

6.6  MECHANIC'S LIENS.   Tenant will not permit any mechanic's liens, or
other liens, to be placed upon the Premises, the Building/s or the Center
during the Lease Term or any extension or renewal thereof, and in case of
the filing of any such lien, Tenant will promptly pay same.  Tenant agrees
to pay all legal fees that might be incurred by Landlord because of any
mechanic's liens being placed upon the Premises, as a result of Tenant's
actions.

6.7  REDELIVERY OF PREMISES.  No later than the last day of the Lease Term
(or any renewals or extensions thereof), Tenant will remove all Tenant's
personal property and repair all injury done by or in connection with
installation or removal of such property and surrender the Premises broom
clean (together with all keys to the Premises) in as good a condition as
they were in at the beginning of the Lease Term, reasonable wear and tear
excepted.

6.8  SIGNS AND ADVERTISEMENTS.     Tenant shall not put upon nor permit to
be put upon any part of the Premises, the Building/s or the Center, any
signs, billboards or advertisements whatever in any location or any form
without the prior written consent of Landlord.  A charge of $50.00 per day
per sign, billboard or advertisement will be assessed against Tenant if
Tenant fails to obtain the written consent of Landlord prior to placing any
such signs.

6.9   USE OF COMMON AREAS.  Tenant shall not use any part of the Center 
exterior to the Premises for outside storage.  No trash, crates, pallets, or 
refuse shall be permitted anywhere on the Center outside of the Building/s by 
Tenant except in enclosed metal containers to be located as directed by 
Landlord.  Tenant shall not park any trucks or trailers, loaded or empty, 
except in specifically marked loading and truck parking locations.

6.10  USE OF PREMISES.  The Premises hereby leased shall be used by the

statutes, ordinances, rules, regulations, orders and requirements in effect 
during the term or any part of the term hereof regulating the use by Tenant 
of the Premises.  Tenant shall not use or permit the use of the Premises in 
any manner that will tend to create waste or a nuisance, or will tend to 
unreasonably disturb such other tenants in the Center.  Tenant, its employees 
and all persons visiting or doing business with the Tenant in the Premises 
shall be bound by and shall observe the Rules and Regulations attached to 
this Lease, as Exhibit A, and such further and other reasonable rules and 
regulations made hereafter by the Landlord relating to the Center or the 
Premises of which notice in writing shall be given to the Tenant and all such 
rules and regulations shall be deemed to be incorporated into and form a part 
of this Lease.

6.11  HAZARDOUS SUBSTANCES.  Tenant shall not cause or permit to be released
(whether by way of uncapping, pouring, spilling, spraying, spreading, attaching,
or otherwise) into or onto the Premises, or the Building/s, or the Center, or
the Common Areas (including the ground and ground water thereunder and the sewer
and drainage systems therein) any hazardous substances (as defined or
established from time to time by applicable local, state or federal law).
Tenant shall immediately notify Landlord if any such release occurs, and, as to
any such release that has been caused or permitted by Tenant: (i) Tenant shall
immediately and entirely remove such released hazardous substance, and in a
manner fully in compliance with all laws pertaining to the removal and storage
or deposit thereof; and (ii) Tenant hereby agrees to hold Landlord harmless of
and from any liability, public or private, resulting to Landlord as a result of
such release.  Further, Tenant shall, upon Landlord's demand and at Tenant's
sole expense, demonstrate to Landlord (through such tests, professional
inspections, sampling or otherwise as is, in Landlord's sole judgment,
sufficient for the purpose) that Tenant has not caused or permitted any such
release of hazardous substances.

ARTICLE VII.  INSURANCE.
- ------------------------

7.1   LIABILITY INSURANCE.  Tenant covenants and agrees to maintain on the
Premises at all times during the Lease Term, or any extension or renewal
thereof, a policy or policies of comprehensive public liability and property
damage insurance with not less than $1,000,000.00 combined single limit for both
bodily injury and property damage.

7.2   FIRE AND EXTENDED COVERAGE INSURANCE.  Landlord shall, throughout the
Lease Term, or any extension or renewal thereof, maintain fire and extended
coverage (FEC) insurance on the property owned by Landlord including Landlord

with such deductibles as Landlord shall determine.  Landlord shall not in any
way or manner insure any property of Tenant or any property that may be in the
Premises not owned by Landlord except for Landlord approved leasehold
improvements.  Tenant shall comply with all insurance regulations so that the
lowest fire, lightning, explosion, extended coverage and liability insurance
rates may be obtained; and nothing shall be done or kept in or on the Premises
by Tenant which will cause an increase in the premium of any such insurance on
the Premises or on any Building/s of which the Premises are a part or on any
contents located therein, over the rate usually obtained for the proper use of
the Premises permitted by this Lease or which will cause cancellation of any
such insurance.

7.3   INDEMNIFICATION OF LANDLORD.  Tenant shall indemnify Landlord and save
Landlord harmless from and against any and all loss (including loss of rentals
payable by Tenant or other tenants) and against all claims, actions, damages,
liability and expenses in connection with loss of life, bodily and personal
injury or damage to property arising form any occurrence in, upon or at the
Premises or any part thereof, or occasioned wholly or in part by any act or
omission of Tenant, or by anyone permitted to be on the Premises by Tenant.
Tenant agrees, at all times, to indemnify and hold Landlord harmless against all
actions, claims, demands, costs, damages or expenses of any kind which may be
brought or made against Landlord or which Landlord may pay or incur by reason of
Tenant's occupancy of the Premises or its negligent performance of or failure to
perform any of its obligations under this Lease.  In case Landlord shall,
without fault on its part, be made a party to any litigation commenced by or
against Tenant, then Tenant shall protect and hold Landlord harmless and shall
pay all costs, expenses and reasonable attorney's fees incurred or paid by
Landlord in connection with such litigation.  See Rider.

ARTICLE VIII.  EMINENT DOMAIN AND DAMAGE OR DESTRUCTION.
- --------------------------------------------------------

8.1   EMINENT DOMAIN.  In the event that title to the whole or a substantial
part of the Premises shall be lawfully  condemned or taken in any manner for any
public or quasi-public use, this lease and the term and estate hereby granted
shall forthwith cease and terminate as of the date of vesting of title and
Landlord shall be entitled to receive the entire award, Tenant hereby assigning
to Landlord the Tenant's interest therein, if any.  However, nothing herein
shall be deemed to give Landlord any interest in or to require Tenant to assign
to Landlord any award made to Tenant for the taking of personal property or
fixtures belonging to Tenant or for the interruption of or damage to Tenant's
business or for Tenant's moving expenses.  A sale to a public or quasi-public
authority under threat of condemnation shall constitute a taking by eminent
domain.  In the event that title to a part of the Buildings other than the
Premises shall be so condemned or taken, Landlord may terminate this lease and
the term and estate hereby granted by notifying Tenant of such termination
within sixty (60) days following the date of vesting of title, and this lease
and the term and estate hereby granted shall expire on the date specified in the
notice of termination, not less than sixty (60) days after the giving of such
notice, as fully and completely as if such date were the date herein set for the
expiration of the Lease Term, and the Rent hereunder shall be apportioned as of
such date.  In the event of any condemnation or taking of any portion of the
parking area of the Center, which does not result in a reduction of the parking
area by more than twenty percent (20%), the terms of this lease shall continue
in full force and effect.  If more than twenty percent (20%) of the parking area
is taken, either party shall have the right to terminate this lease upon giving
written notice to the other party within thirty (30) days of such taking.

8.2   DAMAGE OR DESTRUCTION.  If the Premises, the Building/s or the Center or
any part thereof is damaged by fire or other casualty, cause or condition
whatsoever and Landlord shall determine not to restore said Premises, Building/s
or Center, Landlord or Tenant may, by written notice to the other given within
sixty (60) days after such damage, terminate this Lease.  Such termination shall
become effective as of the date of the damage.  If this Lease is not terminated
as above provided and if the Premises are made partially or wholly untenantable,
Landlord, at its expense, shall restore the same with reasonable promptness to
the condition in which Landlord furnished the Premises to Tenant at the
commencement of the Lease Term as to those items that were provided to the
Premises at Landlord's expense without any reimbursement by Tenant.  Landlord
shall be under no obligation to restore any alteration, improvements or
additions to the Premises made by Tenant or paid for by Tenant, including, but
not limited to, any of the initial tenant finish done or paid for by Tenant or
any subsequent changes, alterations or additions made by Tenant or reimbursed by
Tenant.


                                          10

<PAGE>

If, as a result of fire or other casualty, cause or condition whatsoever the 
Premises are made partially or wholly untenantable and, if Landlord has not 
given the sixty (60) day notice above provided for and fails within one 
hundred twenty (120) days after such damage occurs to eliminate substantial 
interference with tenant's use of said Premises or substantially to restore 
said Premises, tenant may terminate this Lease after the end of said one 
hundred twenty (120) days, effective as of the date such damage occurs, by 
notice to Landlord given not later than ten (10) days after expiration of 
said one hundred twenty (120) day period.  If the Premises are rendered 
totally untenantable but this Lease is not terminated, all rent shall abate 
from the date of the fire or other relevant cause or condition until the 
Premises are ready for occupancy and reasonably accessible to Tenant.  If a 
portion of the Premises is untenantable, and Tenant and Landlord decide to 
have Tenant remain in the premises, rent shall be prorated on a per diem 
basis and apportioned in accordance with the portion of the Premises which is 
usable by the Tenant until the damaged part is ready for the Tenant's 
occupancy.  In all cases, due allowance shall be made for reasonable delay 
caused by adjustment of insurance loss, strikes, labor difficulties or any 
cause beyond Landlord's reasonable control.  For the purposes of this Lease, 
said Premises shall be considered tenantable so long as and to the extent 
that the Premises are occupied.  In any event, Tenant shall be responsible 
for the removal, or restoration, when applicable, of all its damaged property 
and debris from the Premises, upon request by Landlord or else Tenant must 
reimburse Landlord for the cost of removal.

                                      RIDER



     This Rider is attached to and made part of that certain Lease (the
     "Lease") dated OCTOBER 1, 1991, by and between GENERAL AMERICAN LIFE
     INSURANCE COMPANY, as Landlord, and STERICYCLE, INC., as Tenant, covering
     the property commonly known as 10390 ENTERPRISE DRIVE, REDLANDS, CA 92374
     (the "Property").  The terms used herein shall have the same definitions as
     set forth in the Lease.  The provisions of this Rider shall supersede any
     inconsistent or conflicting provisions of the Lease.

     1. RENT ABATEMENT PERIOD AND OCCUPANCY DATE

     Landlord shall give Tenant a total of four months of rent abatement as
     follows: January 1, 1992 to and including April 30, 1992, ("the rent
     abatement period"). Such occupancy during the rent abatement period shall
     be subject to all the provisions, terms and conditions of said Lease
     (including the payment of base rent, taxes, insurance and common area
     maintenance expenses) provided, however, that the base rent payable during
     said rent abatement period shall be payable only if an event of default
     under the Lease occurs at any time during the term of the Lease or during
     the term of the rent abatement period, in which event, on the occurrence of
     such event of default, all such rent for the rent abatement period shall
     become immediately due and payable to Landlord.  If, at the end of
     expiration of the original said Lease, Tenant is not in default
     hereunder, and have made all rent and other payments provided for
     thereunder, Landlord agrees to waive any payment of base rent for the rent
     abatement period.  In any event, tenant improvement expenses (per paragraph
     4 of this Rider), taxes, insurance and common area maintenance expenses are
     due and payable as of the commencement date of the Lease.  The provisions
     hereof shall not affect the termination date of the Lease set forth
     therein.


     2. EARLY TERMINATION OF LEASE

     The Lease Start Date is January 1, 1992.  The Rent Abatement period starts
     as of that date.  Stericycle will have the right to terminate the signed
     lease up to June 30, 1992 for the following reasons:

          A.   Stericycle does not obtain the operating authority from the State
          of California.

          B.   Stericycle does not obtain a Conditional Use Permit from the City
          of Loma Linda.

          C.   Stericycles' Board of Directors does not approve the project.

     Should Stericycle terminate this lease prior to June 30, 1992, Stericycle
     will forfeit to General American the following:

          A.   If prior to April 30, 1992:  Security Deposit plus one month's
          rent.

          B.   If after April 30 and prior to June 30, 1992: Security deposit
          and one month's rent plus an additional month's rent for each month
          after April 30, 1992 (up to a maximum of two months additional rent).

                                      LEASE

THIS LEASE is made as of this 25th day of February, 1992, by and between EML
Associates, a New York General Partnership (hereinafter called "Landlord") and
Stericycle, Inc. (hereinafter called "Tenant").

PREMISES

1.     Landlord leases to Tenant and Tenant leases from Landlord, upon the 
   terms and conditions hereinafter set forth, those premises (the "Premises")
   outlined in red on Exhibit A and described in the Basic Lease Information.
   The Premises may be all or part of the building (the "Building") or of the
   project (the "Project") which may consist of more than one building.  The
   Building and Project are outlined in blue and green respectively on
   Exhibit A.

POSSESSION AND LEASE COMMENCEMENT

2. B.  CONSTRUCTION OF IMPROVEMENTS.  In the event this Lease pertains to a
   Building to be constructed or improvements to be constructed within a
   Building, the provisions of this Paragraph 2.B. shall apply in lieu of the
   provisions of Paragraph 2.A. above and the term commencement date ("Term
   Commencement Date") shall be the earlier of the date on which: (1) Tenant
   takes possession of some or all of the Premises, or (2) the improvements
   constructed or to be constructed in the Premises shall have been
   substantially completed in accordance with the plans and specifications
   described on Exhibit B, whether or not substantial completion of the Building
   itself shall have occurred.  Landlord shall provide Tenant with notification
   of the date on which the Improvements shall be substantially completed no
   less than two weeks prior to the substantial completion of the Improvements.
   If for any reason Landlord cannot deliver possession of the Premises to
   Tenant on the Estimated Term Commencement Date, Landlord shall not be subject
   to any liability therefor, nor shall Landlord be in default hereunder.  In
   the event of any dispute as to substantial completion of work performed or
   required to be performed by Landlord, the certificate of Landlord's architect
   or general contractor shall be conclusive.  Substantial completion shall have
   occurred notwithstanding Tenant's submission of a checklist to Landlord,
   which Tenant shall submit, if at all, within forty (40) days after the Term
   Commencement Date.  Tenant shall, upon demand, execute and deliver to
   Landlord a letter of acceptance of delivery of the Premises.

   See Addendum 1

TERM

3.     The Term of this Lease shall commence on the Term Commencement Date and
   continue in full force and effect for the number of months specified as the
   Length of Term in the Basic Lease Information or until this Lease is
   terminated as otherwise provided herein.  If the Term Commencement Date is a
   date other than the first day of the calendar month, the Term shall be the
   number of months of the Length of Term in addition to the remainder of the
   calendar month following the Term Commencement Date.

4. A.  GENERAL.  Tenant shall use the Premises for the Permitted Use and for no
   other use or purpose.  Tenant shall control Tenant's employees, agents,
   customers, visitors, invitees, licensees, contractors, assignees and
   subtenants (collectively, "Tenant's Parties") in such a manner that Tenant
   and Tenant's Parties cumulatively do not exceed the Parking Density at any
   time.  Tenant and Tenant's Parties shall have the nonexclusive right to use,
   in common with other parties occupying the Building or Project, the parking
   areas and driveways of the Project, subject to such rules and regulations as
   Landlord may from time to time prescribe.

   B.  LIMITATIONS.  Tenant shall not permit any odors, smoke, dust, gas,
   substances, noise or vibrations to emanate from the Premises, nor take any
   action which would constitute a nuisance or would disturb, obstruct or
   endanger any other tenants of the Building or Project in which the Premises
   are situated or interfere with their use of their respective premises.
   Storage outside the Premises of materials, vehicles (except Tenant's vehicles
   parked directly in front of Premise's dock door which in no way shall block
   traffic flow through the Project) or any other items is prohibited.  Tenant
   shall not use or allow the Premises to be used for any improper, immoral,
   unlawful or objectionable purpose, nor shall Tenant cause or maintain or
   permit any nuisance in, on or about the Premises.  Tenant shall not commit or
   suffer the commission of any waste in, on or about the Premises.  Tenant
   shall not allow any sale by auction upon the Premises, or place any loads
   upon the floors, walls or ceilings which endanger the structure, or place any
   harmful liquids in the drainage system of the Building or Project.  No waste,
   materials or refuse shall be dumped upon or permitted to remain outside the
   Premises except in trash containers placed inside exterior enclosures
   designated for that purpose by Landlord.  Landlord shall not be responsible
   to Tenant for the non-compliance by any other tenant or occupant of the
   Building or Project with any of the above-referenced rules or any other terms
   or provisions of such tenant's or occupant's lease or other contract.

   C.  COMPLIANCE WITH REGULATIONS.  By entering the Premises, Tenant accepts
   the Premises in the condition existing as of the date of such entry, subject
   to all existing of future applicable municipal, state and federal and other
   governmental statutes, regulations, laws and ordinances, including zoning
   ordinances and regulations governing and relating to the use, occupancy and
   possession of the Premises and the use, storage, generation and disposal of
   Hazardous Materials (hereinafter defined) in, on and under the Premises
   (collectively "Regulations").  Except for pre-existing violations, both known
   and unknown, Tenant shall, at Tenant's sole expense, strictly comply with all
   Regulations now in force or which may hereafter be in force relating to the
   Premises and the use of the Premises and/or the use, storage, generation of
   Hazardous Materials in, on and under the Premises.  Tenant shall


                                       -3-
<PAGE>

   at its sole cost and expense obtain any and all licenses or permits necessary
   for Tenant's use of the Premises.  Tenant shall promptly comply with the
   requirements of any board of fire underwriters or other similar body now or
   hereafter constituted.  Tenant shall not do or permit anything to be done in,
   on, or about the Premises or bring or keep anything which will in any way
   increase the rate of any insurance upon the Premises,  Building or Project,
   or upon any contents therein or cause a cancellation of said insurance or
   otherwise affect said insurance in any manner.  Tenant shall indemnify,
   defend, protect and hold Landlord harmless from and against any loss, cost,
   expense, damage, attorneys' fees or liability arising out of the failure of
   Tenant to comply with any applicable law or comply with the requirements as
   set forth herein.

   D.  HAZARDOUS WASTES.  Tenant shall not cause, or allow any of Tenant's
   Parties to cause, any Hazardous Materials to be used, generated, stored or 
   disposed of on or about the Premises, the Building of the Project. As used 
   in this Lease, "Hazardous Materials" shall include, but not be limited to, 
   hazardous, toxic and radioactive materials and those substances defined as 
   "hazardous substances," "hazardous materials," "hazardous wastes," "toxic 
   substances," or other similar designations in any federal, state, or local
   law, regulation, or ordinance.  Landlord shall have the right at all 
   reasonable times to inspect the Premises and to conduct tests and 
   investigations to determine whether Tenant is in compliance with the 
   foregoing provisions, the costs of all such inspections, test, and 
   investigations to be borne by Tenant. Tenant shall indemnify, defend, 
   protect and hold Landlord harmless from and against all liabilities, losses,
   costs and expenses, demands, causes of action, claims or judgments directly 
   or indirectly arising out of the use, generation, storage or disposal of 
   Hazardous Materials by Tenant or any of Tenant's Parties, which indemnity 
   shall include, without limitation, the cost of any required or necessary 
   repair, cleanup or detoxification, and the preparation of any closure or 
   other required plans, whether such action is required or necessary prior to
   or following the termination of this Lease. Neither the written consent by 
   Landlord to the use, generation, storage or disposal of Hazardous Materials 
   nor the strict compliance by Tenant with all laws pertaining to Hazardous 
   Materials shall excuse Tenant from Tenant's obligation of indemnification 
   pursuant to this Paragraph 4.D.  Tenant's obligations pursuant to the 
   foregoing indemnity shall survive the termination of this Lease.

RULES AND REGULATIONS

5.     Tenant shall faithfully observe and comply with any rules and regulations
   Landlord may from time to time prescribe in writing for the purpose of
   maintaining the proper care, cleanliness, safety, traffic flow and general
   order of the Premises or Project.  Tenant shall cause Tenant's Parties to
   comply with such rules and regulations.  Landlord shall not be responsible to
   Tenant for the non-compliance by any other tenant or occupant of the Building
   or Project with any of the rules and regulations.

RENT

6. A.  BASE RENT.  Tenant shall pay to Landlord, without demand throughout the
   Term, Base Rent as specified in the Basic Lease Information, payable in
   monthly installments in advance on or before the first day of each calendar
   month, in lawful money of the United States, without deduction or offset
   whatsoever, at the address specified in the Basic Lease Information or to
   such other place as Landlord may from time to time designate in writing.
   Base Rent for the first full month of the Term shall be paid by Tenant upon
   Tenant's execution of this Lease.  If the obligation for payment of Base Rent
   commences on other than the first day of a month, then Base Rent shall be
   prorated and the prorated installment shall be paid on the first day of the
   calendar month next succeeding the Term Commencement Date.

   B.  ADDITIONAL RENT.  All monies other than Base Rent required to be paid by
   Tenant hereunder, including, but not limited to, the interest and late charge
   described in Paragraph 26.D., any monies spent by Landlord pursuant to
   Paragraph 30, and Tenant's Proportionate Share of Basic Operating Cost, as
   specified in Paragraph 7 of this Lease, shall be considered additional rent
   ("Additional Rent").  "Rent" shall mean Base Rent and Additional Rent.

BASIC OPERATING COST

7. A.  BASIC OPERATING COST.  In addition to the Base Rent required to be paid
   hereunder, Tenant shall pay as Additional Rent, Tenant's Proportionate Share,
   as defined in the Basic Lease Information, of Basic Operating Cost in the
   manner set forth below.  Landlord shall account for each item of Basic
   Operating Cost as either a cost attributable to the Building or to the
   Project, as determined by Landlord in Landlord's sole discretion, and unless
   provided to the contrary in this Lease, Tenant shall pay the applicable
   Tenant's Proportionate Share of each such Basic Operating Cost, as set forth
   in the Basic Lease information.  Basic Operating Cost shall mean all
   reasonable expenses and costs of every kind and nature which Landlord shall
   pay or become obligated to pay, because of or in connection with the
   management, maintenance, preservation and operation of the Project and its
   supporting facilities (determined in accordance with generally accepted
   accounting principles, consistently applied) including but not limited to the
   following:

   (1) TAXES.  All real property taxes, possessory interest taxes, business or
   license taxes or fees, service payments in lieu of such taxes or fees, annual
   or periodic license or use fees, excises, transit charges, housing fund
   assessments, open space charges, assessments, levies, fees or charges,
   general and special, ordinary and extraordinary, unforeseen as well as
   foreseen, or any kind (including fee "in-lieu" of any such tax or assessment)
   which are assessed, levied, charged, confirmed, or imposed by any public
   authority upon the Project, its operations or the Rent (or any portion or
   component thereof) (all of the foregoing being hereinafter collectively
   referred to as "real property taxes"), or any tax imposed in substitution,
   partially or totally, of any tax previously included within the definition of
   real property taxes, or any additional tax the nature of which was previously
   included within the definition of real property taxes, except (a) inheritance
   or estate taxes imposed upon or assessed against the Project, or any part
   thereof or interest therein, and (b) taxes computed upon the basis of net
   income of Landlord or the owner of any interest therein, except as otherwise
   provided in the following sentence.  Basic Operating Cost shall also include
   any taxes, assessments, or any other fees imposed by any public authority
   upon or measured by the monthly rental or other charges payable hereunder,
   including, without limitation, any gross income tax or excise tax levied by
   the local governmental authority in which the Project is located, the federal
   government, or any other governmental body with respect to receipt of such
   rental, or upon, with respect to or by reason of the development, possession,
   leasing, operation, management, maintenance, alteration, repair, use or
   occupancy by Tenant of the Premises or any portion thereof, or upon this
   transaction or any document to which Tenant is a party creating or
   transferring an interest or an estate in the Premises.


                                       -4-
<PAGE>

   (2) INSURANCE.  All insurance premiums and costs, including but not limited
   to, any deductible amounts, premiums and cost of insurance incurred by
   Landlord, as more fully set forth in Paragraph 8.A. herein.

   (3) REPAIRS AND IMPROVEMENTS.  Repairs, replacements and general maintenance
   for the Premises, Building and Project (except for those repairs expressly
   made the financial responsibility of Landlord pursuant to the terms of this
   Lease, repairs to the extent paid for by proceeds of insurance or by Tenant
   or other third parties, and alterations attributable solely to tenants of the
   Project other than Tenant).  Such repairs, replacements, and general
   maintenance shall include the reasonable cost of any capital improvements
   made to or capital assets acquired for the Project, Building, or Premises
   after the Term Commencement Date that reduce any other Basic Operating Cost,
   are reasonably necessary for the health and safety of the occupants of the
   Project, or are made to the Building by Landlord after the date of this Lease
   and are required under any governmental law or regulation, such costs or
   allocable portions thereof to be amortized over such reasonable period as
   Landlord shall reasonably determine, together with interest on the
   unamortized balance at the "prime rate" charged at the time such improvements
   or capital assets are constructed or acquired by Wells Fargo Bank, N.A. (San
   Francisco), plus two (2) percentage points, but in no event more than the
   maximum rate permitted by law.

   (4) SERVICES.  All reasonable expenses relating to maintenance, janitorial
   and service agreements and services, and costs of supplies and equipment used
   in maintaining the Premises, Building and Project and the equipment therein
   and the adjacent sidewalks, driveways, parking and service areas, including,
   without limitation, alarm service, window cleaning, elevator maintenance,
   Building exterior maintenance and landscaping.

   (5) UTILITIES.  Utilities which benefit all or a portion of the Premises,
   Building or Project.

   (6) MANAGEMENT FEE.  A management and accounting cost recovery fee equal to
   ten percent (10%) of the Basic Operating Cost.

   (7) LEGAL AND ACCOUNTING.  Legal and accounting expenses relating to the
   Project, including the cost of audits by certified public accountants.

   In the event that the Building is not fully occupied during the fiscal year
   of the Term as determined by Landlord, an adjustment shall be made in
   computing the Basic Operating Cost for such year so that Tenant pays an
   equitable portion of all variable items of Basic Operating Cost, as
   reasonably determined by Landlord; provided, however, that in no event shall
   Landlord be entitled to collect in excess of one hundred percent (100%) of
   the total Basic Operating Cost from all of the tenants in the Building
   including Tenant.

   Basic Operating Cost shall not include specific costs incurred for the
   account of, separately billed to and paid by specific tenants.
   Notwithstanding anything herein to the contrary, in any instance wherein
   Landlord, in Landlord's sole discretion, deems Tenant to be responsible for
   any amounts greater than Tenant's Proportionate Share, Landlord shall have
   the right to allocate costs in any manner Landlord deems appropriate.  In no
   event will Tenant pay for more than its reasonable pro-rata share of Basic
   Operating Costs.

   B.  PAYMENT OF ESTIMATED BASIC OPERATING COST.  "Estimated Basic Operating
   Cost" for any particular year shall mean Landlord's estimate of the Basic
   Operating Cost for such fiscal year made prior to commencement of such fiscal
   year as hereinafter provided.  Landlord shall have the right from time to
   time to revise its fiscal year and interim accounting periods so long as the
   periods as so revised are reconciled with prior periods in accordance with
   generally accepted accounting principles applied in a consistent manner.
   During the last month of each fiscal year during the Term, or as soon
   thereafter as practicable, Landlord shall give Tenant written notice of the
   Estimated Basic Operating Cost for the ensuing fiscal year.  Tenant shall pay
   Tenant's Proportionate Share of the Estimated Basic Operating Cost with
   installments of Base Rent for the fiscal year to which the Estimated Basic
   Operating Cost applies in monthly installments on the first day of each
   calendar month during such year, in advance.  If at any time during the
   course of the fiscal year, Landlord determines that Basic Operating Cost is
   projected to vary from the then Estimated Basic Operating Cost by more than
   ten percent (10%), Landlord may, by written notice to Tenant, revise the
   Estimated Basic Operating Cost for the balance of such fiscal year, and
   Tenant's monthly installments for the remainder of such year shall be
   adjusted so that by the end of such fiscal year Tenant has paid to Landlord
   Tenant's Proportionate Share of the revised Estimated Basic Operating Cost
   for such year.

   C.  COMPUTATION OF BASIC OPERATING COST ADJUSTMENT.  "Basic Operating Cost
   Adjustment" shall mean the difference between Estimated Basic Operating Cost
   and Basic Operating Cost for any fiscal year determined as hereinafter
   provided.  Within one hundred twenty (120) days after the end of each fiscal
   year, as determined by Landlord, or as soon thereafter as practicable,
   Landlord shall deliver to Tenant a statement of Basic Operating Cost for the
   fiscal year just ended, accompanied by a computation of Basic Operating Cost
   Adjustment.  If such statement shows that Tenant's payment based upon
   Estimated Basic Operating Cost is less than Tenant's Proportionate Share of
   Basic Operating Cost, then Tenant shall pay to Landlord the difference within
   twenty (20) days after receipt of such statement.  If such statement shows
   that Tenant's payments of Estimated Basic Operating Cost exceed Tenant's
   Proportionate Share of Basic Operating Cost, then (provided that Tenant is
   not in default under this Lease) Landlord shall pay to Tenant the difference
   within twenty (20) days after delivery of such statement to Tenant.  If this
   Lease has been terminated or the Term hereof has expired prior to the date of
   such statement, then the Basic Operating Cost Adjustment shall be paid by the
   appropriate party within twenty (20) days after the date of delivery of the
   statement.  Should this Lease commence or terminate at any time other than
   the first day of the fiscal year, Tenant's Proportionate Share of Basic
   Operating Cost adjustment shall be prorated by reference to the exact number
   of calendar days during such fiscal year that this Lease is in effect.

   D.  BASIC OPERATING COST.  Notwithstanding anything to the contrary in this
   Lease, Tenant's obligation to pay Tenant's Proportionate Share of Taxes and
   Insurance shall be as follows:

   -   BASIC OPERATING COST.  Tenant shall not be obligated to pay Tenant's
       Proportionate Share of Taxes and Insurance until after the first year of
       Lease ending one (1) year from the Term Commencement Date.

   -   BASIC OPERATING COST EXPENSE STOP.  Beginning in the second year of Lease
       and throughout the Term thereafter, Tenant shall pay Tenant's
       Proportionate Share of Taxes and Insurance to the extent that such amount
       exceeds $701.37 per month which includes $629.48 for taxes, and $71.89
       for insurance.


                                       -5-
<PAGE>

   E.  TENANT AUDIT.  In the event that Tenant shall dispute the amount set
   forth in any statement provided by Landlord under Paragraph 7.B. or 7.C.
   above, Tenant shall have the right, not later than thirty (30) days following
   the receipt of such statement and upon the condition that Tenant shall first
   deposit with Landlord the full amount in dispute, to cause Landlord's books
   and records with respect to Basic Operating Cost for such fiscal year to be
   audited by certified public accountants selected by Tenant and subject to
   Landlord's reasonable right of approval.  The Basic Operating Cost Adjustment
   shall be appropriately adjusted on the basis of such audit.  If such audit
   discloses a liability for a refund in excess of seven and a half percent 
   (7 1/2%) of Tenant's Proportionate Share of the Basic Operating Cost 
   Adjustment previously reported, the cost of such audit shall be borne by 
   Landlord: otherwise the cost of such audit shall be paid by Tenant.  If 
   Tenant shall not request an audit in accordance with the provisions of the 
   Paragraph 7.E. within twenty (20) days after receipt of Landlord's statement
   provided pursuant to Paragraph 7.B. or 7.C., such statement shall be final 
   and binding for all purposes hereof.

INSURANCE AND INDEMNIFICATION

8. A.  LANDLORD'S INSURANCE.  Landlord agrees to maintain insurance insuring the
   Building against fire, lightning, vandalism and malicious mischief
   (including, if Landlord elects, "All Risk" coverage, earthquake, and/or flood
   insurance), in an amount not less than eighty percent (80%) of the
   replacement cost thereof, with deductibles and the form and endorsements of
   such coverage as selected by Landlord.  Such insurance may also include, at
   Landlord's option, insurance against loss of Base Rent and Additional Rent,
   in an amount of Base Rent and Additional Rent payable by Tenant for a period
   of at least twelve (12) months commencing on the date of loss.  Such
   insurance shall be for the sole benefit of Landlord and under Landlord's sole
   control.  Landlord shall not be obligated to insure any furniture, equipment,
   machinery, goods or supplies which Tenant may keep or maintain in the
   Premises, or any leasehold improvements, additions or alterations within the
   Premises.  Landlord may also carry such other insurance as Landlord may deem
   prudent or advisable, including, without limitation, liability insurance in
   such amounts and on such terms as Landlord shall determine.

   B.  TENANT'S INSURANCE.

   (1) PROPERTY INSURANCE.  Tenant shall procure at Tenant's sole cost and
   expense and keep in effect from the date of this Lease and at all times until
   the end of the Term, insurance on all personal property and fixtures of
   Tenant and all improvements made by or for Tenant to the Premises, insuring
   such property for the full replacement value of such property.

   (2) LIABILITY INSURANCE.  Tenant shall procure at Tenant's sole cost and
   expense and keep in effect from the date of this Lease and at all times until
   the end of the Term either Comprehensive General Liability insurance or
   Commercial General Liability insurance applying to the use and occupancy of
   the Premises and the Building, and any part of either, and any areas adjacent
   thereto, and the business operated by Tenant, or by any other occupant on the
   Premises.  Such insurance shall include Broad Form Contractual Liability
   insurance coverage insuring all of Tenant's indemnity obligations under this
   Lease.  Such coverage shall have a minimum combined single limit of liability
   of at least One Million Dollars ($1,000,000.00), and a general aggregate
   limit of One Million Dollars ($1,000,000.00).  All such policies shall be
   written to apply to all bodily injury, property damage or loss, personal
   injury and other covered loss, however occasioned, occurring during the
   policy term, shall be endorsed to add Landlord and any party holding an
   interest to which this Lease may be subordinated as an additional insured,
   and shall provide that such coverage shall be primary and that any insurance
   maintained by Landlord shall be excess insurance only.  Such coverage shall
   also contain endorsements:  (i) deleting any employee exclusion on personal
   injury coverage; (ii) including employees as additional insureds; (iii)
   deleting any liquor liability exclusion; and (iv) providing for coverage of
   employer's automobile non-ownership liability.  All such insurance shall
   provide for severability of interests; shall provide that an act or omission
   of one of the named insureds shall not reduce or avoid coverage to the other
   named insureds; and shall afford coverage for all claims based on acts,
   omissions, injury and damage, which claims occurred or arose (or the onset of
   which occurred or arose) in whole or in part during the policy period.  Said
   coverage shall be written on an "occurrence" basis or at Tenant's option a
   "claims made" basis provided tenant will maintain a retroactive date back to
   the inception of this Lease, or will take such other action that will provide
   uninterrupted coverage.

   (3) GENERAL INSURANCE REQUIREMENTS.  All coverages described in this
   Paragraph 8.B. shall be endorsed to provide Landlord with thirty (30) days'
   notice of cancellation or change in terms.  If at any time during the Term
   the amount or coverage of insurance which Tenant is required to carry under
   this Paragraph 8.B. is, in Landlord's reasonable judgment, materially less
   than the amount or type of insurance coverage reasonably and customarily
   carried by owners or tenants of properties located in the general area in
   which the Premises are located which are similar to and operated for similar
   purposes as the Premises, Landlord shall have the right to require Tenant to
   increase the amount or change the types of insurance coverage required under
   this Paragraph 8.B.  All insurance policies required to be carried under this
   Lease shall be written by companies rated A + XII or better in "Best's
   Insurance Guide" and authorized to do business in California.  Any deductible
   amounts under any insurance policies required hereunder shall be subject to
   Landlord's prior written approval.  In any event deductible amounts shall not
   exceed Ten Thousand Dollars ($10,000.00).  Tenant shall deliver to Landlord
   on or before the Term Commencement Date, and thereafter at least thirty (30)
   days before the expiration dates of the expiring policies, certified copies
   of Tenant's insurance policies, or a certificate evidencing the same issued
   by the insurer thereunder, showing that all premiums have been paid for the
   full policy period; and, in the event Tenant shall fail to procure such
   insurance, or to deliver such policies or certificates, Landlord may, at
   Landlord's option and in addition to Landlord's other remedies in the event
   of a default by Tenant hereunder, procure the same for the account of Tenant,
   and the cost thereof shall be paid to Landlord as Additional Rent.

   C.  INDEMNIFICATION.  Landlord shall not be liable to Tenant for any loss or
   damage to person or property caused by theft, fire, acts of God, acts of a
   public enemy, riot, strike, insurrection, war, court order, requisition or
   order of governmental body or authority or for any damage or inconvenience
   which may arise through repair or alteration of any part of the Building or
   Project or failure to make any such repair, unless caused by Landlord's
   willful negligence, except as expressly otherwise provided in Paragraph 10.
   Tenant shall indemnify, defend by counsel acceptable to Landlord, protect and
   hold Landlord harmless from


                                       -6-
<PAGE>

   and against any and all liabilities, losses, costs, damages, injuries or
   expenses, including reasonable attorneys' fees and court costs, arising out
   of or related to:  (1) claims of injury to or death of persons or damage to
   property occurring or resulting directly or indirectly from the use or
   occupancy of the Premises, or from activities of Tenant, Tenant's Parties or
   anyone in or about the Premises or Project, or from any cause whatsoever; (2)
   claims for work or labor performed, or for materials or supplies furnished to
   or at the request of Tenant in connection with performance of any work done

     may be relied upon by any mortgagee, beneficiary, purchaser or prospective

     damage, injury, expense or liability caused by such event of default, an 
     Tenant shall pay to Landlord, on demand, the amount so applied in order

     proposed assignment or subtenant, failure by Landlord to approve a proposed
     assignee or subtenant shall not cause a termination of this Lease. Upon a
     termination under this paragraph 21.A, Landlord may lease the Premises to
     any party, including parties with whom Tenant has negotiated an assignment
     or sublease, without incurring any liability to Tenant.

     by reason of Tenant's default or of such termination.

     (2)  CONTINUATION AFTER DEFAULT. Even though an event of default may have

     to the provisions of Paragraph 26.B(1) hereof, Landlord shall have the
     rights and remedies of a Landlord provided Section 1951.2 of the Civil Code
     of the State of California, or successor code sections. Upon such
     termination, in addition to any other rights and remedies to which Landlord
     may be entitled under applicable law, Landlord shall be entitled to recover
     from the Tenant: (1) the worth at the time of award of the unpaid Rent and
     other amounts which had been earned at the time of termination, (2) the
     worth at the time of award of the amount by which the unpaid Rent which
     would have been earned after termination until the time of award exceeds
     the amount of such Rent loss that Tenant proves could have been reasonable
     avoided; and (4) any other amount necessary to compensate Landlord for all
     the determent proximately caused by Tenant's failure to perform Tenant's
     obligations under this Lease or which, in the ordinary course of things,
     would be likely to result therefrom. The "worth at the time of award" of
     the amounts referred to in (1) and (2), above shall be computed at the
     lesser of the "prime rate" as announced from time to time by Wells Fargo
     Bank, N.A. (San Francisco), plus two (2) percentage points, or the maximum
     interest rate allowed by law ("Applicable Interest Rate"). The "worth an
     the time of award" of the amount referred to in (3) above shall be computed
     by discounting such amount at the Federal Discount Rate of the Federal
     Reserve Bank of San Francisco at the time of the award, I this Lease
     provides for any periods during the Term during which Tenant is not
     required to pay base Rent or if Tenant otherwise receives a Rent
     concession, then upon the occurrences of an event of default, Tenant shall
     owe the Landlord the full amount of such Base Rent or value of such
     concession, plus interest at the Applicable interest Rate, calculated from
     the date that such Base Rent or Rent Concession would have been payable.

     D.   LATE CHARGE. If any installment of Rent is not paid within five (5)
     days of when due, such amount shall bear interest at the Applicable
     Interest Rate from the date on which said payment shall be due until the
     date on which the Landlord receives said payment, In addition, Tenant shall
     pay Landlord a late charge equal to five percent (5%) of the delinquency,
     to compensate Landlord for the loss of the use of the amount not paid and
     the administrative costs caused by the delinquency, the parties agreeing
     that Landlord's damage by virtue of such delinquency would be difficult to
     compute and the amount stated herein represents a reasonable estimate
     thereof. This provision shall not relieve Tenant's obligation to pay Rent
     at the time and in the manner herein specified.

<PAGE>

     E.  REMEDIES CUMULATIVE. All rights, privileges and elections or remedies
     of the parties are cumulative and not alternative, to the extent permitted
     by law and except  as otherwise provided herein.

     not, within ten (10) days following the imposition of any such lien, cause
     the same to be released of record payment or posting of a proper bond.
     Landlord shall have, in addition to all other remedies provided herein and
     by law, the right, but not the obligation, to cause the same to be released

     posted on the Premises any notices permitted or required by law, or which
     Landlord shall deem proper, for the protection of the Landlord, the
     Premises, the Project and by other party having an interest therein, from
     mechanics' and materialmen's liens, and tenant shall give Landlord not less
     than ten(10) business days prior written notice of the commencement of any
     work in the Premises or Project which could give rise to a claim for 
     mechanics' and materialmen's liens.

     written consent, which shall not be unreasonably withheld, may substitute

     Premises Shall be deemed to be the Premises for all purposes hereunder;

     Landlord has committed to provide in t the premises. 

     (5)  Tenant has the right to operate within use and occupancy the New 
     Premises under all applicable state and local regulations.

TRANSFERS BY LANDLORD

29.       In the event of a sale r conveyance by Landlord of the Building or a
     Foreclosure by any creditor of Landlord, the same shall operate to release
     Landlord from any liability upon any of the covenants or conditions,
     express or implied, herein contained in favor of Tenant, to the extent
     required to be performed after the passing of title to Landlord's
     successor-in-interest of Landlord under this Lease with respect

30.       All covenants and agreements to be performed by Tenant under any of
     the terms of the Lease shall be performed by Tenant at Tenant's sole cost
     and expense and without any abatement of Rent. If Tenant shall fail to any
     sum of money, other than Base Rent and Basic Operating Cost, required to be
     paid by Tenant hereunder or shall fail to perform any other act on Tenant's
     part to be performed hereunder, and such failure shall continue for five
     (5) days after notice thereof by Landlord, Landlord may, but shall not be
     obligated to do so, and without waiving or releasing Tenant from any
     obligations of Tenant, make such payment or perform any such act on
     Tenant's part to be made or performed. All sums, so paid by Landlord and
     all necessary incidental costs together with interest thereon at the
     Applicable interest Rate from the date of such payment by Landlord shall be
     payable to Landlord on demand and Tenant covenants to pay such sums, and
     Landlord shall have, in addition to any other right or remedy of Landlord,
     the same right and remedies in the event of non-payment thereof by Tenant
     as in the case of default by Tenant in the payment of Base Rent and Basic
     Operating Cost.

WAIVER

31.       If either Landlord or Tenant waives the performance of any term,
     covenant or condition contained in this Lease, such waiver shall not be
     deemed to be a waiver of any subsequent breach of the same or any other
     term, covenant or condition contained herein. The acceptance of Rent by
     Landlord shall not constitute a waiver of any preceding breach by Tenant of
     any Term, covenant or condition of this Lease, regardless of Landlord's
     knowledge of such preceding breach at the time Landlord accepted such Rent.
     Failure by Landlord to enforce any of the Terms, covenants or conditions of
     this Lease for any length of time shall not be deemed to waive or to
     decrease the right of the Landlord to insist thereafter upon Strict
     performance by the Tenant. Waiver by Landlord of any term, covenant, or
     condition contained in this Lease may only be made by a written document
     signed by Landlord.

                               the Lease term.  In no event shall the
                               annualized increase be less than four percent
                               (4%) or a multiplication factor of 1.0816 nor
                               greater than six percent (6%) or a
                               multiplication factor of 1.1236.  For example,
                               if the rent for months 61-90 was $7,787.52, then
                               the minimum increase would be $8,422.98 and the
                               maximum increase would be $8,750.06.

                             MASTER LEASE AGREEMENT

                                  No. 15O-10310
                  dated as of February 11, 1994, by and between

Lessor:  Ziegler Leasing Corporation    and Lessee: Stericycle, Inc.
         215 N. Main Street                 1419 Lake Cook Road, Suite 410
          West Bend, Wisconsin 53095        Deerfield, Illinois 60015


     1.   LEASE. Lessor agrees to lease to Lessee and Lessee agrees to lease
from Lessor the personal property including intangibles (the "Equipment")
described in one or more Rental Schedules (herein called "Schedule(s)") in the
form of Exhibit A attached hereto, to this Master Lease Agreement. Each such
Schedule incorporates by this reference, the terms and conditions set forth in
this Master Lease Agreement and constitutes a separate lease (the"Lease").  The
lease of Equipment under each Lease shall be for such term and such rents as may
be agreed to by execution of the Schedules and this Master Lease Agreement shall
control and be effective as to all such Schedules, the same as though set forth
herein unless expressly amended or modified in writing for particular 
Schedules.  The term "Equipment" as used in this Master Lease Agreement shall 
refer to items leased under all Schedules and the terms hereof, unless 
expressly amended or modified in writing, shall apply equally to all such 
Equipment.

     2.   TERM AND RENT. The Initial Term for each item of Equipment shall be
for the period specified in the Schedules, and Lessee shall pay Lessor,
throughout the Initial Term for the use of the Equipment, the Rent specified in
the Schedules.  The Initial Term and Rent with respect to each item of Equipment
shall commence as set out in the applicable Schedule.

     3.   LATE CHARGES. Time is of the essence in this Lease.  If any Rent or
other amount due hereunder are not paid within ten (10) days after the due date
thereof, Lessor shall have the right to add and collect and Lessee to pay (a) a
late charge on, and in addition to, such unpaid Rent or other charges, equal to
five percent (5%) of such unpaid Rent or a lesser amount it established by any
state or federal thereto, (b) interest on such Rent or other charges from, the
due date until paid at the highest contract rate enforceable against Lessee 
under applicable law, (c) a reasonable collection fee not to exceed $500 for 
additional administrative costs.

     4.   DISCLAIMER OF WARRANTIES. Lessee acknowledges that Lessor is not the
manufacturer of the Equipment, nor manufacturer's agent, and Lessee represents
that Lessee has selected the Equipment leased hereunder based upon Lessee's
judgment prior to having requested Lessor to purchase the same for leasing to
Lessee, and Lessee agrees that as between Lessor and Lessee, the Equipment
leased hereunder is of a design, size, fitness and capacity selected by Lessee
and that Lessee is satisfied that the same is suitable and fit for its intended
purposes. LESSEE FURTHER AGREES THAT LESSOR HAS MADE AND MAKES NO
REPRESENTATIONS OR WARRANTIES OF WHATSOEVER NATURE, DIRECTLY OR INDIRECTLY,
EXPRESSED OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY REPRESENTATIONS OR
WARRANTIES WITH RESPECT TO SUITABILITY, DURABILITY, FITNESS FOR USE AND
MERCHANTABILITY OF ANY SUCH EQUIPMENT, THE PURPOSES AND USES OF THE LESSEE THE
CHARACTERIZATION OF THE LEASE FOR TAX, ACCOUNTING OR OTHER PURPOSES, COMPLIANCE
OF THE EQUIPMENT WITH APPLICABLE GOVERNMENTAL REQUIREMENTS, OR  



                                        1
<PAGE>


OTHERWISE.  Lessee specifically waives all rights to make claim against Lessor
herein for breach of any warranty of any kind whatsoever.  Notwithstanding the
foregoing, Lessee shall be entitled to the benefit of any applicable
manufacturer's warranties received by Lessor and to the extent assignable, such
warranties are hereby assigned by Lessor to Lessee for the term of the 
applicable Schedules.  Lessor shall not be liable to Lessee for any loss, damage
or expense of any kind or nature caused directly or indirectly by any Equipment
leased hereunder or for the use or maintenance thereof, or for the failure of
operations thereof, or for the repairs, service or adjustment thereto, or by any
delay or failure to provide any thereof, or by any interruption of service or
loss of use thereof or for any loss of business or any other damage whatsoever
and howsoever caused.  No defect or unfitness of the Equipment shall relieve
Lessee of the obligation to pay Rent, or to perform any other obligation under
this Lease.

     5.   USE, OPERATION AND MAINTENANCE. Lessee shall use the Equipment in 
the manner for which it was designed and intended, solely for Lessee's 
business purposes, in accordance with all manufacturer manuals and 
instructions and in compliance with all applicable laws, regulations and 
orders.  Lessee, at Lessee's own cost and expense, shall keep the Equipment 
in good repair, condition and working order, ordinary wear and tear excepted, 
and shall furnish all parts, mechanisms, devices and servicing required 
therefore and necessary to comply with all applicable health and safety 
standards. If commercially available, Lessee shall maintain in force a 
maintenance agreement with respect to the Equipment with the manufacturer 
thereof or such other party as may be acceptable to Lessor, and the 
Equipment, upon return to Lessor, shall qualify for such program without 
additional expense. All replacement parts and repairs at any time made to or 
placed upon the Equipment shall become the property of Lessor.  Lessee may, 
with Lessor's prior written consent, make such alterations, modifications or 
additions to the Equipment as Lessee may deem desirable in the conduct of its 
business; provided the same shall not diminish the value or utility of the 
Equipment, or cause the loss of any warranty thereon or any certification 
necessary for the maintenance thereof, and shall be readily removable without 
causing damage to the Equipment. Upon return to Lessor the Equipment as to 
which such alterations, modifications or have been made, Lessee, if requested 
to do so by Lessor, shall remove the same and restore the Equipment to its
original condition, reasonable wear and tear only being excepted, and, if not 
so removed, title thereto shall automatically vest in Lessor.

LESSEE SHALL KEEP THE EQUIPMENT FREE AND CLEAR FROM ALL LIENS, CHARGES,
ENCUMBRANCES, LEGAL PROCESS AND CLAIMS.  LESSEE SHALL NOT ASSIGN, SUBLET,
HYPOTHECATE, SELL, TRANSFER OR PART WITH POSSESSION OF THE EQUIPMENT OR ANY
INTEREST IN THIS LEASE, AND ANY ATTEMPT TO DO SO SHALL BE NULL AND VOID AND
SHALL CONSTITUTE A DEFAULT HEREUNDER. Lessee shall not move the Equipment from
the location noted in the Schedules without the prior written consent of Lessor,
which consent shall not be unreasonably withheld.  Neither this Lease nor any
interest in the Equipment is assignable or transferable by Lessee by operation
of law. Lessee agrees not to waive its right to use and possess the Equipment in
favor of any party other than Lessor and further agrees not to abandon the
Equipment to any party other than Lessor. So long as Lessee faithfully performs
and meets each and every term and condition to be performed or met by Lessee
under this Lease, Lessee's quiet and peaceful possession of the Equipment will
not be disturbed by Lessor or anyone claiming by, through or on behalf of
Lessor.

     6.   TITLE. The Equipment is and at all times shall remain the sole and
exclusive personal property of Lessor (subject to Section 19 hereof).  No right,
title or interest in the Equipment shall pass to Lessee other than the right to
maintain possession and use of the Equipment for the full lease term,
conditioned upon Lessee's compliance with the terms and conditions of this
Lease. If requested by Lessor, Lessee shall affix to or place on the Equipment
plates or markings indicating Lessor's ownership. Lessee covenants and agrees
that the Equipment is, and will at all times, remain the personal property of
Lessor (subject to Section 19 hereof).  If requested by Lessor, Lessee will
obtain a waiver, in recordable form, from all persons with a real property
interest in the premises wherein the Equipment may be located, waiving any


                                        2

<PAGE>

claim with respect thereto. Lessor shall have the right from time to time during
normal business hours to enter upon Lessee's premises or elsewhere for the
purpose of confirming the existence, condition, and proper maintenance of the
Equipment or for any other reasonable business purpose.

     7 . RENT ADJUSTMENT.  The Effective Lease Rate will remain fixed for the 
duration of the Initial Term.  Prior to the funding date, the date that 
Lessor pays the Purchase Price of the Equipment as set forth in the Schedule, 
Lessor may adjust the Rent in order to maintain its originally anticipated 
rate of return if; (i) there is a change in the yield on the U.S. Treasury 
Securities, as quoted in the Federal Reserve statistical release H.15 (519), 
from the Index Basis specified on the Schedules, (ii) the Rental Commencement 
Date as set forth in the Schedules, is not on or before the Commitment 
Expiration Date specified on the Schedules; (iii) Lessee fails to deliver 
documentation as requested by Lessor; (iv) the Equipment cannot be acquired 
by Lessor at a cost equal to the invoice cost specified on the Schedules; or 
(v) there is a material change in the Equipment residual values as determined 
by Lessor.

     8.   TAXES. Lessee shall promptly reimburse Lessor for, or shall pay
directly if so requested by Lessor, as additional Rent, all taxes, charges and
fees which may now or hereafter be imposed or levied by any governmental body or
agency upon or in connection with the purchase, ownership, lease, possession,
use or location of the Equipment or otherwise in connection with the
transactions contemplated by the Lease, excluding, however, all taxes on or
measured by the net income of Lessor, and shall keep the Equipment free and
clear of all levies, liens or encumbrances arising therefrom. Lessor shall file,
as owner and party responsible for payment of tax, personal property tax return
relating to the Equipment unless otherwise provided in writing.  Lessee shall
promptly reimburse Lessor for all property taxes levied on or assessed against
the Equipment during the Initial Term and all renewals or extensions, without
any proration whatsoever. Failure of Lessee to promptly pay amounts due
hereunder shall be the same as failure to pay any installment of Rent. If Lessee
is requested by Lessor to file any returns or remit payments directly to any
governmental body or agency as provided for hereunder, Lessee shall provide
proof of said filing or payment to Lessor upon request.

     9.   LOSS OR DAMAGE OF EQUIPMENT. Lessee hereby assumes and shall bear the
risk of loss for destruction of or damage to the Equipment from any and every
cause whatsoever, whether or not insured, until the Equipment is returned to
Lessor. No such loss or damage shall impair any obligation of Lessee under this
Lease which shall continue in full force and effect. In event of damage to or
theft, loss or destruction of the Equipment (or any item thereof), Lessee shall
promptly notify Lessor in writing of such fact and of all details with respect
thereto, and shall, within thirty (30) days of such event, at Lessor's option,
(a) place the same in good repair, condition and working order or, (b) replace
the Equipment (or any item thereof) with like personal property in good repair,
condition and working order and transfer clear title to such replacement 
property to Lessor whereupon such property shall be subject to this Lease and 
be deemed the Equipment for purposes hereof; or, (c) pay Lessor an amount 
equal to the sum of (i) all Rent accrued to the date of such payment, plus 
(ii) the "Stipulated Loss Value" as set forth in the Schedules, whereupon 
this Lease shall terminate, except for Lessee's duties under Section 11 
hereof, solely with respect to the Equipment (or any item thereof) for which 
such payment is received by Lessor. Upon payment of the amount set forth in 
(c), the Rent for such Schedules shall be reduced proportionately. Any 
insurance proceeds received with respect to the Equipment (or any item 
thereof) shall be applied, in the event option (c) is elected, in reduction 
of the then unpaid obligations, including the Stipulated Loss Value, of 
Lessee to Lessor, if not already paid by Lessee, or, if already paid by 
Lessee, to reimburse Lessee for such payment, or, in the event option (a) or 
(b) is elected, to reimburse Lessee for the costs of repairing, restoring or 
replacing the Equipment (or any item thereof) upon receipt by Lessor of 
evidence, satisfactory to Lessor, that such repair, restoration or 
replacement has been completed, and an invoice therefor.

     10.  INSURANCE. Lessee shall keep the Equipment insured against theft and
all risks of loss or damage from every cause whatsoever for not less than the
greater of the replacement


                                        3

<PAGE>

cost, new, or the Stipulated Loss Value of the Equipment and shall carry 
public liability insurance, both personal injury and property damage, 
covering the Equipment and Lessee shall be liable for all deductible portions 
of all required insurance. All said insurance shall be in form and amount and 
with companies satisfactory to Lessor.  All insurance for theft, loss or 
damage shall provide that losses, if any, shall be payable to Lessor, and all 
such liability insurance shall name Lessor (or Lessor's assignee as 
appropriate) as additional insured and shall be endorsed to state that it 
shall be primary insurance as to Lessor. Any other insurance obtained by or 
available to Lessor shall be secondary insurance. Lessee shall pay the 
premiums therefor and deliver to Lessor a certificate of insurance or other 
evidence satisfactory to Lessor that such insurance coverage is in effect; 
provided, however, that Lessor shall be under no duty either to ascertain the 
existence of or to examine such insurance policies or to advise Lessee in the 
event such insurance coverage shall not comply with the requirements hereof. 
Each insurer shall agree by endorsement upon the policy or policies issued by 
it or by independent instrument furnished to Lessor, that it will give Lessor 
thirty (30) days written notice to the effective date of any alteration or 
cancellation of such policy. The proceeds of such insurance payable as a 
result of loss of or damage to the Equipment shall be applied as set out in 
Section 9 hereof. Lessee hereby irrevocably appoints Lessor as Lessee's 
attorney-in-fact to make claim for, receive payment of, and execute and 
endorse all documents, checks or drafts received in payment for loss or 
damage under any said insurance policies.

In case of the failure of Lessee to procure or maintain said insurance or to
comply with any other provision of this Lease, Lessor shall have the right but
shall not be obligated, to effect such insurance or compliance on behalf of
Lessee.  In that event, all monies spent by and expenses of Lessor in effecting
such insurance or compliance shall be deemed to be additional Rent, and shall be
paid by Lessee to Lessor upon demand.

     11.  LESSEE INDEMNITY. Lessee assumes liability for and shall indemnify, 
save, hold harmless (and, if requested by Lessor, defend) Lessor, it's 
officers, directors, employees, agents or assignees from and against any and 
all claims, actions, suits or proceedings of any kind and nature whatsoever, 
including all damages, liabilities, penalties, costs, expenses and legal fees 
(hereinafter "Claim(s)") based on, arising out of, connected with or 
resulting from this Lease of the Equipment, including without limitation the 
manufacture, selection, purchase, delivery, acceptance, rejection, 
possession, use, operation, ownership, return or disposition of the 
Equipment, and including without limitation Claims arising in contract or 
tort (including negligence, strict liability or otherwise), arising out of 
latent defects (regardless of whether the same are discoverable by Lessor or 
Lessee) or arising out of any trademark, patent or copyright infringement. If 
any Claim is made against Lessee or Lessor, the party receiving notice of 
such Claim shall promptly notify the other, but the failure of such person 
receiving notice so to notify the other shall not relieve Lessee of any 
obligation hereunder.

Without limiting the generality of the foregoing indemnities, Lessee shall 
indemnify and hold harmless the Lessor and its affiliates, directors, 
officers, employees and agents from and against any and all losses, damages, 
penalties, injuries, claims, actions and suites, including legal expenses, of 
whatsoever kind and nature, arising out of, based upon or with respect to any 
Environmental Claim relating to the delivery, lease, possession, maintenance, 
uses, condition, return, operation or ownership of the Equipment. As used 
herein, the term (i) "Environmental Claim" shall refer to any: (I) civil or 
administrative judgment, settlement, judicial or administrative order, 
directive, lien, fine, penalty or other assessment by any federal, state or 
local environmental authority, corrective action imposed or other obligation 
imposed under Environmental Law for the cleanup of releases or threatened 
releases of Hazardous Waste or for the reimbursement of federal, state or 
local environmental authorities for cost and expenses incurred in connection 
with the cleanup of releases or threatened releases of Hazardous Waste or 
requiring the Lessor to bring the Equipment into compliance with any 
applicable Environmental Law; or (II) judgment against or settlement with the 
Lessor by any person for personal injury damages arising out of exposure to 
Hazardous Waste; (ii) "Environmental Laws" means any federal, state or local

<PAGE>

regulations promulgated thereunder relating to pollution or protection of the
environment, including laws relating to the omissions, discharges, releases or
threatened releases or Hazardous Wastes into the environment (including without
limitation, ambient air, surface water, ground water or land), or otherwise
relating to he manufacture, processing, distribution, use, treatment, storage,
disposal, transport or handling of Hazardous Wastes; and (iii) "Hazardous
Waste(s)" means hazardous substances, materials or wastes (including, without
limitation, biologically hazardous or radioactive materials.

     12.  TAX INDEMNITY. Lessee acknowledges that (1) Lessor intends to claim 
and take the accelerated cost recovery deductions available in the manner and 
as provided by section 168 and related sections of the Internal Revenue Code 
of 1986, as amended, and regulations adopted thereunder (the "Code") as in 
effect on the date hereof (such deductions being referred to hereinafter as 
"Tax Benefits") and (2) the Rent payable hereunder has been computed upon the 
assumption that such Tax Benefits shall be available to Lessor.  Lessee 
represents and warrants to Lessor that Lessor shall be entitled to take such 
Tax Benefits and that all of the Equipment is, at and after the time of 
delivery of the Equipment to the location set forth in the Schedules, new, 
unless designated otherwise on the Schedules. Lessee further represents and 
warrants that it has not, and will not, at any time from such delivery 
through the term of this Lease take any action or omit to take any action 
(whether or not the same is permitted or required hereunder) which will 
result in the loss by Lessor of all or any part of the Tax Benefits. For 
purposes of this Section 12, the term "Lessor" shall include the entity or 
entities, if any, with which Lessor consolidates its tax return.

     13.  RENEWAL. Lessee may renew each Schedule in accordance with its terms
for any mutually agreeable period of time at a fair market value renewal rent
payable on the first day of each month during the term of the renewal if Lessee
gives notice thereof at least four (4) months prior to the then scheduled
expiration of the Initial Term (including any renewal) and is not in default
under such Schedule.

     14.  RETURN OF EQUIPMENT.  Lessee shall give Lessor ninety (90) days 
written notice prior to the expiration of the Initial Term of its intent to 
return the Equipment.  Upon expiration of the Initial Term or other 
termination pursuant to the terms of this Lease, Lessee shall immediately 
return the Equipment and all related accessories, to such place within the 
continental United States as is designated by Lessor. The Equipment shall, at 
Lessee's sole expense, be crated and shipped in accordance with the 
manufacturer's specifications, freight prepaid and properly insured. If the 
Equipment, upon its return, is not in good repair, condition and working 
order, ordinary wear and tear excepted, and has not been maintained in 
accordance with Section 5 hereof, Lessee shall promptly reimburse Lessor for 
all reasonable costs incurred to place the Equipment in such condition.

Lessee agrees that if for any reason the Equipment is returned to Lessor, prior
to such return the Equipment shall be in a condition which is free from any
Hazardous Wastes or residue.  Lessee shall provide Lessor with a manifest from a
certified industrial hygienist certifying the proper decontamination and
cleaning of the Equipment in compliance with all federal, state and local laws
and regulations.

     15.  AUTOMATIC RENEWAL.  The Lease shall automatically extend for a renewal
period of not less than sixty (60) days if; (a) written notice as specified in
Sections 13 and 14 hereof is not received by Lessor; or (b) such notice is
received by lessor but the Equipment is not returned upon the expiration of the
Initial Term. Lessee shall pay as Rent to Lessor an amount based on the average
monthly rent during the Initial Term on the due dates set out in the Schedules
until terminated by either party by giving ninety (90) days prior written
notice.  All terms and conditions of this Lease shall continue in full force and
effect during any extension or renewal hereof.

     16.  DEFAULT AND REMEDIES. (a) Lessee shall be in default hereunder if 
(i) Lessee fails to pay Rent or any other payment required hereunder within 
ten (10) days of the due date thereof, (ii) Lessee fails to observe, keep or 
perform any other term or condition of this Lease and such failure continues 
for twenty (20) days following receipt of written notice thereof from Lessor, 
(iii) any representation or warranty made by Lessee herein or in any document 
delivered to Lessor in connection herewith shall prove to be false or 
misleading, or (iv) Lessee defaults under any other obligation to Lessor. (b) 
If Lessee is in default, Lessor shall have the right to take any one or more 
of the following actions: (i) proceed by appropriate court action or actions 
at law or in equity to enforce performance by Lessee of the term and 
conditions of this Lease and/or recover damages for the breach thereof; 
and/or (ii) by written notice to Lessee, which notice shall apply to all 
Schedules hereunder except as specifically excluded therefrom by Lessor, 
declare due and payable, and Lessee shall without further demand, forthwith 
pay to Lessor an amount equal to any unpaid Rent then due as of the date of 
such notice plus, as liquidated damages or loss of the bargain and not as a 
penalty, an amount equal to the Stipulated Loss Value as set forth in the 
Schedules, and Lessee shall return the Equipment to Lessor as provided in 
Section 13.  Should Lessee fail to return the Equipment within (5) days of 
receipt of such notice, Lessor may, personally, or by its agents, and with or 
without notice of legal process, enter upon the premises where the Equipment 
is located, without liability for trespass or other damages, and repossess 
the Equipment free from all claims by Lessee. Return or repossession of the 
Equipment shall not constitute a termination of this Lease unless Lessor so 
notifies Lessee in writing. With respect to Equipment returned to or 
repossessed by Lessor, if Lessor has not terminated this Lease, Lessor will, 
in such manner and upon such terms as Lessor may determine in its sole 
discretion, either sell such Equipment at one of more public or private sales 
or re-lease the Equipment. The proceeds of sale or re-lease shall be applied 
in the following order or priority: (i) to pay all Lessor's fees, costs and 
expenses for which Lessee is obligated pursuant to (c), below; (ii) to the 
extent not previously paid by Lessee, to pay Lessor its liquidated damages 
hereunder and all other sums then remaining unpaid hereunder, and (iii) to 
reimburse Lessee for any sums previously paid by Lessee to Lessor as 
liquidated damages; and (iv) any surplus shall be retained by Lessor.  In the 
event the proceeds of sale or re-lease are less than the sum of the amounts 
payable under (i) and (ii), Lessee shall pay Lessor such deficincy, 
forthwith. The Proceeds of a credit sale or re-lease shall be discounted to 
their present value at the prime rate in effect at the inception of the 
Schedules plus four hundred (400) basis points (4%). (c) Lessee shall be 
liable for all legal and collection fees, costs and expenses arising from 
Lessee's default and the exercise of Lessor's remedies hereunder, including 
costs of repossessions, storage, repairs, reconditioning and sale or 
re-leasing of the Equipment. (d) In the event that any court of jurisdiction 
determines that any provision of this Section 16 is invalid or unenforceable 
in whole or in part, such determination shall not prohibit Lessor from 
establishing its damages sustained as a result of any breach of this Lease in 
any action or proceeding in which Lessor seeks to recover such damages. Any 
repossession or sale or re-lease of the Equipment shall not bar an action for 
damages for breach of this Lease, as hereinabove provided, and the bringing 
of an action or the entry of judgment against Lessee shall not bar Lessor's 
right to repossess the Equipment. No express or implied waiver by Lessor of 
any default shall in any way be, or be construed to be, a continuing waiver 
or a waiver of any future or subsequent default.

          17.  FURTHER ASSURANCES.  Lessee agrees, at the request of Lessor, 
to execute and deliver to Lessor any financing statements, fixture filings or 
other instruments necessary for expedient filing, recording or perfecting the 
interest and title of Lessor in this Lease and the Equipment agrees that a 
copy of this Lease and any Schedule may be so filed, and agrees that all 
costs incurred in connection therewith (including, without limitation, filing 
fees and taxes) shall be paid by Lessee, and agrees to promptly, at Lessee's, 
expense, deliver such other documents and assurances, and take such further 
action as Lessor may request, in order to effectively carry out the intent 
and purpose of this Lease and Schedules. Additionally, Lessee agrees that 
where permitted by law, a copy of the financing statement may be filed in 
lieu of the original.  Lessee shall, as soon as practicable, deliver to 
Lessor, Lessee's future quarterly and annual reports of financial condition, 
prepared in accordance with generally accepted accounting principles, in a 
manner

                                        6

<PAGE>
consistently applied; which Lessee represents and warrants shall fully and
fairly present the true financial condition of Lessee.  Lessee shall provide
Lessor monthly with a statement that there has been no material adverse change
in the financial condition of Lessee and that the Lessee is not in default under
the Lease or any other loan agreement to which the Lessee is a party.  Lessee's
covenants, representations, warranties and indemnities contained in Section 8,
11, 12 and 20 are made for the benefit of Lessor and shall survive, remain in
full force and effect and be enforceable after the expiration or termination of
this Lease for any reason.

          18.  ACCEPTANCE OF EQUIPMENT: NON CANCELLABLE.  Lessee's acceptance of
the Equipment shall be conclusively and irrevocably evidenced by Lessee signing
the Certificate of Acceptance in the form of Exhibit B attached hereto and upon
acceptance, the Schedules shall be noncancelable for the Initial Term thereof. 
If Lessee cancels or terminates the Schedules after its execution and prior to
delivery of the Equipment or if Lessee fails or refuses to sign the Certificate
of Acceptance as to all or any part of the Equipment within a reasonable time,
not to exceed five (5) days, after the Equipment has been delivered, in which
event Lessee will be deemed to have cancelled the Schedule, Lessee shall
automatically assume all of Lessor's purchase obligations for the Equipment and
Lessee agrees to indemnify and defend Lessor from any claims, including any
demand for payment of the purchase price for the Equipment, by the manufacturer
or seller of the Equipment. In addition thereto, Lessee shall pay Lessor (a) all
of Lessor's out-of-pocket expenses and (b) a sum equal to one percent (1%) of
the total rents for the lease term as liquidated damages, the exact sum of which
would be extremely difficult to determine and is reasonably estimated hereby, to
reasonably compensate Lessor for credit review, document preparation, ordering
equipment and other administrative expenses.  Lessor may apply any advance Rent
payments to sums due from Lessee under (a) and (b) above.

          19.  ASSIGNMENT.  Lessee acknowledges and agrees that Lessor may, 
at any time, without notice to or consent of Lessee, assign its rights but 
not its obligations under this Lease and/or mortgage, or pledge or sell the 
Equipment. Such assignee or mortgagee (collectively the "Assignee") may 
re-assign this Lease and/or mortgage without notice to Lessee.  Any such 
Assignee shall have and be entitled to exercise any and all rights and powers 
of Lessor under this Lease, but such Assignee shall not be obligated to 
perform any of the obligations of Lessor hereunder other than Lessor's 
obligation not to disturb Lessee's quiet and peaceful possession of the 
Equipment and unrestricted use thereof for its intended purpose during the 
term thereof and for as long as Lessee is not in default of any of the 
provisions hereof.

          Without limiting the foregoing, Lessee further acknowledges and agrees
that in the event Lessee receives written notice of an assignment from Lessor,
Lessee will pay all Rent and any and all other amounts payable by Lessee under
any Schedule to such Assignee or as instructed by Lessor, notwithstanding any
defense or claim of whatever nature, whether by reason of breach of such
Schedule or otherwise which it may now or hereafter have as against Lessor
(Lessee reserving its right to make claims directly against Lessor).  Lessee
agrees to confirm in writing receipt of notice of assignment as may be
reasonably requested by Assignee.

          Lessee shall not be named as a defendant provided Lessee is not in
default, in any foreclosure or other proceeding which my be instituted by such
Assignee as to the Lease or the Equipment.

          Lessee shall continue to deal exclusively with Lessor with respect to
the matters covered by this Lease.  Lessor shall at all times during the term of
the Lease be specifically authorized by the Assignee to act on the Assignee's
behalf in this regard, and shall execute or caused to be executed, by the
Assignee any documents necessary or desirable to carry out the provisions of
this Section or any other Section referred to herein.

          20.  REPRESENTATIONS AND WARRANTIES.  Lessee represents and warrants
to Lessor that: (i) the making of this Lease and any Schedule thereto executed
by Lessee are duly


                                        7

<PAGE>
authorized on the part of Lessee and upon execution thereof by Lessee and Lessor
they shall constitute valid obligations binding upon, and enforceable against,
Lessee ; (ii) neither the making of this Lease or such Schedule, nor the due
performance thereof by Lessee, including the commitment and payment of the Rent,
shall result in any breach of, or constitute a default under, or violation of,
Lessee's certificate of incorporation, by-laws, or any agreement to which
Lessee is a party or by which Lessee is bound; (iii) Lessee is in good standing
in its state of incorporation and in any jurisdiction where the Equipment is
located, and is entitled to own properties and to carry on business therein; and
(iv) no approval, consent or withholding of objection is required from any
governmental authority or entity with respect to the entering into, or
performance of this Lease or such Schedules by Lessee.

Lessee shall provide Lessor a Certified Copy of it's Corporate Resolutions and
Certificate of Incumbency substantially in the form of Exhibit C attached
hereto.

          21.  NOTICES.  Any notice required or given hereunder shall be deemed
          properly given (i) three (3) business days after mailed first class,
          or certified mail, return receipt requested, postage prepaid,
          addressed to the designated recipient at its address set forth at the
          heading hereof or such other address as such party may advise by
          notice given in accordance with this provision or (ii) upon receipt by
          the party to whom addressed if given in writing by personal delivery,
          commercial courier service, telecopy or other means which provides a
          permanent record of the delivery of such notice.

          22.  LESSEE'S OBLIGATIONS UNCONDITIONAL: NO OFFSET.  This Lease is a
net lease and except as expressly provided for herein, the Lessee shall not be
entitled to any abatement or reduction of rent and Lessee hereby agrees that
Lessee's obligation to pay all rent and other amounts hereunder shall be
absolute and unconditional under all circumstances.

          23.  COUNTERPARTS.  Each Schedule may be executed in one or more
counterparts, each of which shall be deemed an original as between the parties
thereto, but there shall be a single executed original of each Schedule which
shall be marked "Counterpart No. 1"; all other counterparts shall be marked with
other counterpart numbers. To the extent, if any, that a Lease constitutes
chattel paper (as such term is defined in the Uniform Commercial Code) no-
security interest in the Schedule may be created through the transfer or
possession of any counterpart other than Counterpart No. 1. The Master Lease
Agreement is incorporated by reference in each of the Schedules and shall not be
chattel paper by itself.

          24.  SPECIAL TERMS.  Lessee agrees that if Lessee hereafter desires to
lease additional equipment and receives a bona fide commitment to lease such
equipment from a third party, then Lessor shall have the right in its sole
discretion, to lease such equipment to Lessee upon the same terms and 
conditions as are contained in such commitment.

          25.  GOVERNING LAW.  This Lease and any Schedules thereto are entered
into, under and shall be construed in accordance with, and governed by, the laws
of the State of Wisconsin without giving effect to its conflicts of laws
principles.  The State of Wisconsin shall have exclusive jurisdiction over any
action or proceeding brought to enforce or interpret this Lease or otherwise in
connection therewith.

          26.  FAIR MARKET VALUE.  As used herein, the term fair market value
shall have the meaning set forth in the applicable Rental Schedule, but shall in
all instances include an amount equal to all associated installation and
deinstallation costs for the Equipment, if any.

          27.  MISCELLANEOUS.  For purposes of this Lease, the term "Rent" as
used herein shall mean and include all amounts payable by Lessee to Lessor
hereunder. The captions of this Lease are for convenience only and shall not 
be read to define or limit the intent of the provision which follows such 
captions.  This Lease contains the entire agreement and understanding 
between 

                                        8

Lessor and Lessee relating to the subject matter hereof.  Any variation or 
modification hereof and any waiver of any of the provisions or conditions 
hereof shall not be valid unless in writing signed by an authorized 
representative of the parties hereto (initial) JPM. Any provision of this 
Lease which is unenforceable in any jurisdiction shall, as to such 
jurisdiction, be ineffective to the extent of such prohibition or 
unenforceability without invalidating the remaining provisions hereof and any 
such prohibition or unenforceability in any jurisdiction shall not invalidate 
or render unenforceable such provision in any other jurisdiction. Lessor's 
failure at any time to require strict performance by Lessee of any of the 
provisions hereof shall not waive or diminish Lessor's right thereafter to 
demand strict compliance therewith or with any other provision. The term 
"Lessee" as used herein shall mean and include any and all Lessees who have 
signed this Lease, each of whom shall be jointly and severally bound thereby.

THIS LEASE IS A NON-CANCELLABLE LEASE. THIS LEASE IS SUBJECT TO THE TERMS AND
CONDITIONS WRITTEN ABOVE WHICH LESSEE ACKNOWLEDGES HAVING READ. THIS LEASE SHALL

          This Rental Schedule dated and effective as of the_____ day

Ziegler Leasing Corporation ("Lessor") and _______________________ ("Lessee").

          All the terms used herein which are defined in the Lease shall have

          1.     The Equipment leased hereunder is as follows:


New/Used       Quantity         Model Number         Serial No.     Equipment

     Lease Terms

          Initial Term:________months      Rental Commencement Date:____________
          Rent $_________payable monthly in advance, plus applicable taxes


     2.   The Initial Term of the lease of the Equipment shall commence upon 
the Acceptance Date as indicated on the Certificate of Acceptance (the "Lease 
Commencement Date") and shall continue until expiration of the number of payment
periods specified above after the Rental Commencement Date, which shall be the
first day of the first month following the Lease Commencement Date. Lessee
hereby authorizes Lessor to insert the Rental Commencement Date upon its receipt
of the Certificate of Acceptance. Rent in the amount specified above, plus
applicable taxes, shall be due on Rental Commencement Date and on the same day
of each and every consecutive payment period thereafter for the Initial Term. 
All Rent shall be due and payable to Lessor at such place as Lessor shall
designate in writing. Additionally, Lessee shall pay, as interim rent, due and
payable monthly in advance, for the period from including the Lease Commencement
Date to and including immediately preceding the Rental Commencement Date and as
additional interim rent, a percentage of daily rent for the portion of invoices
paid for the period from and including the date Lessor makes Payment to the
vendor to and including the day preceding the Acceptance Date.  The daily rent
will be calculated on a 360 day year;

     3.   Stipulated Loss Values as set out on Exhibit I attached hereto and
incorporated herein;

     4.   Options. Notwithstanding anything contained in the Lease to the
contrary, so long as no default shall have occurred and be continuing, Lessee
may, at Lessee's option, (i) purchase the Equipment leased pursuant to this
Rental Schedule on an "as is, where is" basis, without representation or
warranty, express or implied, at the end of the Initial Term at a price equal to
the Fair Market Value, not to exceed 11% of the original Purchase Price thereof,
plus applicable taxes, or (ii) extend the term of the Initial Term with respect
to the Equipment leased pursuant to this Rental Schedule for the Fair Market
Rental, plus applicable taxes, and for a period of time mutually

                                  10

<PAGE>agreeable to Lessor and Lessee.  "Fair Market Rental" shall be equal to 
the monthly rental which could be obtained in an arms-length transaction 
between an informed and willing lessee and an informed and willing lessor 
under no compulsion to lease. "Fair Market Value" shall be equal to the value 
which would be obtained in an arms-length transaction between an informed and 
willing buyer and an informed and willing Seller under no compulsion to sell, 
and in such determination, costs of removal of the Equipment from its 
location of current use shall not be a deduction from such value.  If Lessee 
and Lessor cannot agree on the Fair Market Value thereof, such value shall be 
determined by appraisal at the sole expense of Lessee.  Appraisal shall be a 
procedure whereby two recognized independent appraisers, one chosen by Lessee 
and one by Lessor, shall mutually agree upon the amount in question.  If the 
appraisers are unable to agree upon the amount in question, a third 
recognized independent appraisers' evaluation shall be binding and conclusive 
on Lessee and Lessor.  This purchase or extension option as applicable shall 
only be available if Lessee gives Lessor ninety (90) days prior written 
notice of Lessee's irrevocable intent to exercise such option and Lessor and 
Lessee shall have agreed to all terms and conditions of such purchase or 
extension prior to the expiration date of the Initial Term.

     5.   All options awarded to Lessee shall apply to all, but not less than
all, Equipment leased hereunder.

     6.   Lessee and Lessor agree that in any event this Rental Schedule shall
be deemed and construed to be a "Finance Lease" as defined by the Uniform
Commercial Code as it applies to leases.

     IN WITNESS WHEREOF, the parties hereto have caused this Rental Schedule to
be duly executed on the date set forth below by their authorized
representatives.

                    THIS RENTAL SCHEDULE CANNOT BE CANCELLED

plus applicable taxes, shall be due on the Rental Commencement Date and on 
the same day of each and every consecutive payment period thereafter for the 
Initial Term.  All Rent shall be due and payable to Lessor at such place as 
Lessor shall designate in writing.  Additionally, Lessee shall pay, as interim 
rent, due and payable monthly in advance, for the period from and including the
Lease Commencement Date to and including the day immediately preceding the 
Rental Commencement Date and as additional interim rent, a percentage of the 
daily rent for the portion of invoices paid for the period from and including 
the date Lessor makes a payment to the vendor to and including the day 
preceding the Acceptance Date.  The daily rent will be calculated on a 360 day
year;

     3.   Stipulate Loss Values as set out on Exhibit I attaced hereto and
incorporated herein;

     4.   Options.  Notwithstanding anything contained in the Lease to the
contrary, so long as no default shall have occurred and be continuing, Lessee
may, at Lessee's option (i) purchase the Equipment leased pursuant to this
Rental Schedule on an "as is, where is" basis, without representation or
warranty, express or implied, at the end of the Initial Term at price equal to
the Fair Market Value, not to exceed 11% of the original Purchase Price thereof,
plus applicable taxes, or (ii) extend the term of the Initial Term with respect
to the Equipment leased pursuant to this Rental Schedule for the Fair Market
Rental, plus applicable taxes, and for a period of time mutually agreeable to
Lessor and Lessee.  "Fair Market Rental" shall be equal to the monthly rental
which could be obtained in an arms-length transaction between an informed and
willing lessee and an informed and willing lessor under no compulsion to lease.
"Fair Market Value" shall be equal to the value which would be obtained in an
arms-length transaction between an informed and willing buyer and an informed
and willing seller under no compulsion to sell, and in such determination, costs
of removal of the Equipment from its location of current use shall not be a
deduction from such value. If Lessee and Lessor cannot agree on the Fair Market
Value thereof, such value shall be determined by appraisal at the sole expense
of Lessee. Appraisal shall be a procedure whereby two recognized independent
appraisers, one chosen by Lessee and one by Lessor, shall mutually agree upon
the amount in question. If the appraisers are unable to agree upon the amount in
question, a third recognized independent appraisers' evaluation shall be binding
and conclusive on Lessee and Lessor. This purchase or extension option as
applicable shall only be available if Lessee gives Lessor ninety (90) days prior
written notice of Lessee's irrevocable intent to exerciase such option and
Lessor and Lessee shall have agreed to all terms and conditions of such purchase
or extension prior to the expiration date of the Initial Term.

     5.   All options awarded to Lessee shall apply to all, but not less than
all, Equipment leased hereunder. 




This is Counterpart Number 2. Only Counterpart Number 1 shall constitute Chattel
Paper.

Lessee:  STERICYCLE OF ARKANSAS, INC.       Master Lease Agreement No.  5244
         3501 Algonquin Road
Address: Rolling Meadows, Illinois 60008    Date:         March 14, 1991

LINC Venture Lease Partners II, L.P. ("Lessor") hereby leases to Lessee and
Lessee leases from Lessor, in accordance with the terms and conditions
hereinafter set forth, the equipment and property together with all replacement
parts, additions, accessories, alterations and repairs incorporated therein or
now or hereafter affixed thereto (herein collectively referred to as the
"Equipment") described in the Equipment Schedules attached hereto and in any
other Equipment Schedules which may be executed by Lessor and Lessee from time
to time ("Schedule" or "Schedules"), all of which are made a part hereof.  For
all purposes of this Master Lease Agreement ("Lease"), each Schedule relating to
one or more items of Equipment shall be deemed a separate lease incorporating
all of the terms and provisions of this Lease.  In the event of a conflict
between the terms of this Lease and the terms and conditions of a Schedule, the
terms and conditions of the Schedule shall govern and control that Schedule.

- --------------------------------------------------------------------------------
1.  Term and Rental

The term of this Lease for any item of Equipment shall be set forth in the
Schedule relating to such item of Equipment and shall commence (the
"Commencement Date") on the Acceptance Date, which shall be the applicable of:
(1) the date of delivery of the Equipment to Lessee; (2) in the case of
Equipment which is the subject of a sale and leaseback between Lessor and
Lessee, the date upon which Lessor purchases such Equipment from Lessee; or (3)
in the case of Equipment requiring installation, the date determined to be the
date of installation of the Equipment.  If the Acceptance Date is other than the
first day of a calendar month, then the Minimum Lease Term shall commence on the
first day of the calendar month following the month which includes the
Acceptance Date and Lessee shall pay to Lessor on such date, in addition to all
other sums due hereunder, an amount equal to one-thirtieth of the amount of the
first monthly rental payment due or to become due hereunder multiplied by the
number of days from and including the Acceptance Date to the Commencement Date
of the Minimum Lease Term set forth in the Schedule.  Lessee agrees to pay the
total rental for the entire term hereof on the terms and conditions set forth
herein, which shall be the total amount of all rental payments set forth in the
Schedule, plus such additional amounts as may become due hereunder or pursuant
to any written modification hereof or additional written agreement hereto. 
Except as otherwise specified in the Schedule, rental payments hereunder shall
be monthly and shall be payable in advance within five days of the first day of
each month during the term of this Lease beginning with the Commencement Date of
the Minimum Lease Term and shall be sent to the address of the Lessor specified
in this Lease or in the Schedule or as otherwise directed by the Lessor in
writing.  Rental payments or any other payments due hereunder not made on or
before the due date shall be overdue and shall be subject to a service charge in
an amount equal to one and one-half percent (1.5%) per month of the overdue
payments (the "Service Charge Rate").  If Lessor shall at any time accept rent
after it shall become due, such acceptance shall not constitute or be construed
as a waiver of any or all of Lessor's rights hereunder, including without
limitation those rights of Lessor set forth in Sections 12 and 13 hereof.

- --------------------------------------------------------------------------------
2.  Title

This is an agreement of lease only.  Lessee shall have no right, title or
interest in or to the Equipment ]eased hereunder, except the express interest
hereunder of Lessee as a lessee to maintain possession and use of the Equipment
for the term of this Lease.  All of the Equipment shall remain personal property
(even though said Equipment may hereafter become attached or affixed to realty)
and the title thereto shall at all times remain in Lessor or its assignees

exclusively.  All replacement parts, modifications, repairs, alterations,
additions and accessories incorporated in or affixed to the Equipment (herein
collectively called "additions" and included in the definition of "Equipment"),
whether before or after the Commencement Date, shall become the property of
Lessor upon being so incorporated or affixed, and shall be returned to Lessor as
provided in Section 3. Upon the request of Lessor, Lessee will affix to the
Equipment, labels or other markings supplied by Lessor indicating its ownership
of the Equipment, and shall keep the same affixed for the entire term of this
Lease.  Lessor is hereby authorized by Lessee, at Lessee's expense, to cause
this Lease or any statement or other instrument in respect thereto, showing the
interest of Lessor in the Equipment, to be filed or recorded, or refiled or
re-recorded, with any governmental agency deemed appropriate by Lessor.  Lessee
agrees to promptly execute and deliver, or cause to be executed and delivered,
to Lessor any statement or instrument requested by Lessor for the purpose of
showing Lessor's interest in the Equipment, including, without limitation,
financing statements, security agreements, and waivers with respect to rights in
the Equipment from any owners or mortgagees of any real estate wherein the
Equipment may be located.  If any item of Equipment includes computer software,
Lessee shall execute and deliver and shall cause Seller to deliver all such
documents as Lessor deems necessary to effectuate assignment of all applicable
software licenses to Lessor.  Lessee shall at its expense (i) indemnify, protect
and defend Lessor's title to the Equipment from and against all persons
claiming against or through Lessee, (ii) at all times keep the Equipment free
from any and all liens, encumbrances, attachments, levies, executions, burdens,
charges or legal process of any and every type whatsoever, (iii) give Lessor
immediate written notice of any matter described in clause (ii), and (iv)
indemnify, protect and save Lessor harmless from any loss, cost or expense
(including reasonable attorneys' fees) caused thereby with respect to any of the
foregoing.

- --------------------------------------------------------------------------------
3.  Acceptance and Return of Equipment

Lessor shall, at any time prior to unconditional acceptance by Lessee of all
items of Equipment listed on any Schedule, have the right to terminate this
Lease with respect to such Schedule and if the Equipment or any portion thereof
has not theretofore been delivered, Lessor may refuse to pay for the Equipment
or any portion thereof or to cause the same to be delivered, if there shall be,
in the reasonable judgment of Lessor, a material adverse change in the financial
condition or credit standing of Lessee or of any guarantor of Lessee's
performance under this Lease since the date of the most recent financial
statements furnished by Lessee or of such guarantor submitted to Lessor which
may, in the reasonable judgment of Lessor, materially impair Lessee's ability to
make rental or other payments required hereunder.  Upon any termination by
Lessor pursuant to this Section or the provisions of any Schedule, Lessee shall
forthwith reimburse to Lessor all sums paid by Lessor with respect to such
Equipment and any interest due hereunder in connection with such Equipment or
the actual or proposed purchase thereof and shall pay to Lessor all other sums
then due under such Schedule, whereupon if Lessee is not in default and has then
fully performed all of its obligations hereunder, Lessor will, upon request of
Lessee, transfer to Lessee without warranty or recourse any rights that Lessor
may then have with respect to such Equipment.  Lessee agrees to promptly execute
and deliver to Lessor (in no event later than 15 days after the Acceptance Date)
a confirmation by Lessee of unconditional acceptance of the Equipment in the
form supplied by Lessor (the "Equipment Acceptance").  Lessee agrees, before
execution of the aforesaid Equipment Acceptance, to inform Lessor in writing of
any defects in the Equipment, or in the installation thereof, which have come to
the attention of Lessee or its agents and which might give rise to a claim by
Lessee against the Seller or any other person.  If Lessee fails to do so, it
shall be deemed an acknowledgment by Lessee (for purposes of this Lease only)
that no such defects in the Equipment or its installation exist to the knowledge
of Lessee or its agents and it shall be conclusively presumed, as between Lessor
and its assignees and Lessee, that such Equipment has been unconditionally
accepted by Lessee for Lease hereunder.  Upon expiration or the earlier
termination of the Lease with respect to any Equipment, Lessee shall, at its own
expense and with ninety (90) days prior written notice to Lessor, assemble,
crate, insure and deliver all of the Equipment and all of the service records
and all software and software documentation subject to this Lease and any
Schedules hereto to Lessor in the same condition and repair as


<PAGE>

Master Lease Agreement
Page 3

when received, reasonable wear and tear resulting only from proper use thereof
excepted, to such reasonable destination within the continental United States as
Lessor shall designate.  Lessee shall, immediately prior to such return of each
item of Equipment, provide to Lessor a letter from the manufacturer of the
equipment or another service organization reasonably acceptable to Lessor
certifying that said item is in good working order, reasonable wear and tear
resulting only from proper use thereof excepted, is eligible for a maintenance
agreement by such manufacturer, if generally available, and any necessary and
applicable state or federal licenses, certifications or approvals, including but
not limited to those required by environmental protection agencies and/or
nuclear regulatory agencies, and all applicable software is included thereon. 
If any software requires relicensing when removed from Lessee's premises, Lessee
shall bear all costs of such relicensing.  If Lessee fails for any reason to
re-deliver the Equipment back to Lessor in accordance with the terms set forth
above, Lessee shall pay to Lessor, at Lessor's election, an amount equal to the
highest monthly payment set forth in the Schedule for a period of not less than
three (3) months and at the end of such period of time, Lessee shall return the
Equipment to Lessor as provided in the Schedule.  If Lessee fails or refuses to
return the Equipment as provided herein at the end of any renewal period, Lessee
shall pay to Lessor, at Lessor's option, an amount equal to one hundred twenty
percent (120%) of the highest monthly payment set forth in the Schedule for each
month or portion thereof, until Lessee so returns the Equipment to Lessor.

- --------------------------------------------------------------------------------
4.  Disclaimer of Warranties

Lessee has exclusively selected and chosen the type and quality of the
Equipment herein leased and the vendor, dealer, seller, manufacturer or supplier
thereof (herein collectively called "Seller"), as set forth in the Schedules. 
Lessor makes no warranty, either express or implied, as to any matter
whatsoever, including without limitation, the condition of the Equipment, its
merchantability or its fitness, adaptability or suitability for any particular
purpose, and as to Lessor, Lessee leases, hires and rents the Equipment "as is."
Lessee understands and agrees that neither the Seller, nor any agent of the
Seller, is an agent of Lessor or is in any manner authorized to waive or alter
any term or condition of this Lease.  Lessor shall not be liable for any loss or
damage suffered by Lessee or by any other person or entity, direct or indirect
or consequential, including, but not limited to, business interruption and
injury to persons or property, resulting from non-delivery or late delivery,
installation, failure or faulty operation, condition, suitability or use of the
Equipment leased by Lessee hereunder, or for any failure of any representations,
warranties or covenants made by the Seller.  Any claims of Lessee shall not be
made against Lessor but shall be made, if at all, solely and exclusively against
the Seller, or any persons other than the Lessor.  Lessor hereby authorizes
Lessee to enforce during the term of this Lease, in its name, but at Lessee's
sole effort and expense, all warranties, agreements or representations, if any,
which may have been made by the Seller to Lessor or to Lessee, and Lessor hereby
assigns to Lessee solely for the limited purpose of making and prosecuting any
such claim, all rights which Lessor has against the Seller for breach of
warranty or other representation respecting the Equipment.

- --------------------------------------------------------------------------------
5.  Care, Transfer and Use of Equipment

Lessee, at its own expense, shall maintain the Equipment in good operating
condition, repair and appearance in accordance with Seller's specifications and
in compliance with all applicable laws and regulations and shall protect the
Equipment from deterioration except for reasonable wear and tear resulting only
from proper use thereof.  When generally offered, Lessee shall, at its expense,
keep a maintenance contract in full force and effect, throughout the term of
this Lease and any Schedule hereto.  The disrepair or inoperability of the
Equipment regardless of the cause thereof shall not relieve Lessee of the
obligation to pay rental hereunder.  Lessee shall not make any material
modification, alteration or addition to the Equipment that would impair
operation of the Equipment for its intended use (other than normal operating
accessories or controls).  Lessee will not, and will not permit anyone other
than the authorized field engineering representatives of the Seller or other
maintenance organization reasonably acceptable to Lessor to effect any
inspection, adjustment, preventative or remedial


<PAGE>

Master Lease Agreement
Page 4


maintenance or repair to the Equipment.  Lessee may not (a) relocate or operate
the Equipment at locations other than the premises of the Lessee specified in
the Schedule (the "Premises"), except with Lessor's prior written consent, which
shall not be unreasonably withheld if such other location is within the
continental United States, or (b) sell, convey, transfer, encumber, part with
possession of, assign or sublease, any item of Equipment or any of its rights
hereunder, and any such purported transaction shall be null and void and of no
force or effect.  In the event of a relocation of the Equipment or any item
thereof to which Lessor consents, all costs (including any additional property
taxes or other taxes and any additional expense of insurance coverage) resulting
from any such relocation, shall be promptly paid by Lessee upon presentation to
Lessee of evidence supporting such cost.  No relocation or sublease permitted
hereunder shall relieve Lessee from any of its obligations under this Lease and
any Schedule hereto.  Lessor shall have the right during normal hours upon
reasonable notice to Lessee, subject to applicable laws and regulations, and all
of Lessee's safety procedures and other applicable state or federal safeguards,
to enter Lessee's Premises where the Equipment is located in order to inspect,
observe, affix labels or other markings, or to exhibit the Equipment to
prospective purchasers or future lessees thereof, or to otherwise protect
Lessor's interest therein.

- --------------------------------------------------------------------------------
6.  Net Lease

This Lease and any Schedule hereto is a net lease, and all payments hereunder
are net to Lessor.  All taxes, assessments, licenses, and other charges
(including, without limitation personal property taxes and sales, use and
leasing taxes and penalties and interest on such taxes) imposed, levied or
assessed on the ownership, possession, rental or use of the Equipment during the
term of this Lease and any Schedule hereto (except for Lessor's federal or state
net income taxes) shall be paid by the Lessee before the same shall become
delinquent, whether such taxes are assessed or would ordinarily be assessed
against Lessor or Lessee.  To the extent possible under applicable law, for
personal property or ad valorum tax return purposes only, Lessee shall include
the Equipment on such returns as may be required, which returns shall be timely
filed by it.  In any event, Lessee shall file all tax returns required for
itself or Lessor and Lessor hereby appoints Lessee as its attorney-in-fact for
such purpose.  In case of failure of Lessee to so pay said taxes, assessments,
licenses or other charges, Lessor may pay all or any part of such items, in
which event the amount so paid by Lessor including any interest or penalties
thereon and reasonable attorneys' fees incurred by Lessor shall be immediately
paid by Lessee to Lessor as additional rental hereunder.  Lessee shall promptly
pay all costs, expenses and obligations of every kind and nature incurred in
connection with the use or operation of the Equipment which may arise or become
due during the term of this Lease and any Schedule hereto, whether or not
specifically mentioned herein.

- --------------------------------------------------------------------------------
7.  Indemnity

Lessee shall and does hereby agree to indemnify, defend and save Lessor and its
assigns harmless of and from any and all liability, loss, cost (including but
not limited to costs of identification, removal, remediation and disposal of
Hazardous Materials (as defined hereinafter) and all reasonable costs associated
with determining whether the Facility and the Equipment are in compliance and
causing compliance with all environmental laws, rules and regulations), injury,
damage (including but not limited to all damages to persons, property, the
Equipment or natural resources), demand and expense (including without
limitation, reasonable attorneys' fees, consultant's fees and laboratory costs)
of any kind whatsoever arising out of, on account of, or in connection with this
Lease, the Equipment leased hereunder and the transactions contemplated hereby,
including, without limitation, the manufacture, selection, purchase, delivery,
installation, ownership, possession, leasing, renting, operation, control, use,
maintenance and the return of the Equipment.  This indemnity shall survive the
term or earlier termination of this Lease and any Schedule hereto.

In addition to and without limitation of all other representations, warranties
and covenants made by Lessee under the Lease, Lessee further represents,
warrants and covenants that Lessee has not used and will not use Hazardous
Materials on, from, or affecting the Equipment and the


<PAGE>

Master Lease Agreement
Page 5

Facility in any manner which violates federal, state or local laws, ordinances,
rules, regulations, or policies governing the use, storage, treatment,
transportation, manufacture, refinement, handling, production or disposal of
Hazardous Materials, and that, to the best of Lessee's knowledge, no prior owner
of the Equipment and the Facility or any tenant, subtenant, prior tenant or
prior subtenant have used or will use Hazardous Materials on, from, or affecting
the Equipment and the Facility in any manner which violates federal, state or
local laws, ordinances, rules, regulations or policies governing the use,
storage, treatment, transportation, manufacture, refinement, handling
production or disposal of Hazardous Materials.  Lessee is in compliance with all
requirements of the Illinois Responsible Property Transfer Act (Ill. Ann. Stat. 
Ch. 30, Sec. 901 et seq.) and with any other law, ordinance, rule or regulation
including but not limited to the following, as applicable: Ark. Code Ann. Ch. 8,
Secs. 7-201, et seq., 7-401 et seq. and 7-501 et seq.; Title VIII Ark. Environ.
Law, Chs. 1-8.  Lessee shall, at Lessee's expense, keep or cause the Equipment
and the Facility to be kept free of Hazardous Materials except to the extent
that the intended use of any particular item of equipment requires contact with
Hazardous Materials.  Without limiting the foregoing, Lessee shall not cause or
permit the Equipment and the Facility or any part thereof to be used to
generate, manufacture, refine, transport, treat, store, handle, dispose,
transfer, produce or process Hazardous Materials, except in compliance with all
applicable federal, state and local laws or regulations, nor shall Lessee cause
or permit, as a result of any intentional or unintentional act or omission on
the part of Lessee or any tenant or subtenant, a release (which release is not
in compliance with applicable state or federal government regulation or
manufacturer specification) of Hazardous Materials onto the Equipment and the
Facility or onto any other property.  Lessee shall comply with and ensure
compliance by all tenants and subtenants with all applicable federal, state and
local laws, ordinances, rules and regulations, whenever and by whomever
triggered, and shall obtain and comply with, and ensure that all tenants and
subtenants obtain and comply with, any and all approvals, registrations or
permits required thereunder.  Lessee shall, (a) at no cost to Lessor, conduct
and complete all investigations, studies, sampling, testing and all remedial,
removal and other actions necessary to clean up and remove all Hazardous
Materials, on, from or affecting the Equipment and the Facility (i) in
accordance with all applicable federal, state and local laws, ordinances, rules,
regulations and policies and (ii) in accordance with the orders and directives
of all federal, state and local governmental authorities, and (b) defend,
indemnify and hold harmless Lessor from and against any claims, demands,
penalties, fines, liabilities, settlements, damages, costs or expenses of
whatever kind or nature, known or unknown, contingent or otherwise, arising out
of, or in any way related to, (i) the presence, disposal, release or threatened
release of any Hazardous Materials which are on, from or affecting the soil,
water, vegetation, buildings, personal property, persons, animals, natural
resources or otherwise; (ii) any personal injury (including wrongful death) or
property damage (real or personal) arising out of or related to such Hazardous
Materials, and/or (iii) any violation of laws, orders, regulations, requirements
or demands of government authorities, which are based upon or in any way related
to such Hazardous materials including, without limitation, reasonable attorney
and consultant fees, investigation and laboratory fees, court costs and
litigation expenses.  In the event the Lease is terminated prior to the
expiration of the Minimum Lease Term, or if there occurs an event of default
under the Indenture such that the Mortgage executed pursuant thereto is
foreclosed, Lessee shall deliver the Equipment and the Facility free of any and
all Hazardous Materials so that the conditions of the Equipment and the Facility
shall conform with all applicable federal, state and local laws, ordinances,
rules or regulations affecting the Equipment and the Facility.  For purposes of
this paragraph, "Hazardous Materials" includes, without limit, any flammable
explosives, radioactive materials, hazardous materials, hazardous wastes,
hazardous or toxic substances or related materials including, without
limitation, petroleum, its derivatives, fractions, by-products or other
hydrocarbons defined in the Comprehensive Environmental Response, Compensation,
and Liability Act of 1980, as amended (42 U.S.C. Sections 9601, et. seq.), the
Clear Water Act (33 U.S.C. Sections 1321 et. seq.), the Clean Air Act (42 U.S.C.
Sections 7401, et seq.), the Toxic Substances Control Act (15 U.S.C. Sections
2601, et. seq.) the Hazardous Materials Transportation Act, as amended (49
U.S.C. Sections 1801 et. seq.), the Resource Conservation and Recovery Act, as
amended (42 U.S.C. Sections 6901, et. seq.), Federal Insecticide, Fungicide,
Rodenticide Act (7 U.S.C. Sections 136, et. seq.), Environmental

Protection Act (5 U.S.C. Section 903 et seq.); Atomic Energy Act of 1954, as
amended (42 U.S.C. Section 2011 et seq.); Toxic Substances Act (15 U.S.C.
Section 2601 et seq.); and in the regulations adopted and publications
promulgated pursuant thereto, or any other Federal, state or local environmental
law, ordinance, rule or regulation.  The provisions of this paragraph shall be
in addition to any and all other obligations and liabilities Lessee may have to
Lessor at common law, and shall survive the termination of this Lease.

- --------------------------------------------------------------------------------
8. INSURANCE

Commencing on the date that risk of loss or damage passes to Lessor from the
Seller and continuing until Lessee has re-delivered possession of the Equipment
to Lessor, Lessee shall, at its own expense, keep the Equipment (including all
additions thereto) insured against all risks of loss or damage from every and
any cause whatsoever in such amounts (but in no event less than the greater of
the replacement value thereof or the amount set forth in the applicable Casualty
Schedule, whichever is higher) and in such form as is satisfactory to Lessor. 
All such insurance policies shall protect Lessor and Lessor's assignee(s) as
loss payees as their interests may appear.  Lessee shall also, at its own
expense, carry public liability insurance, with Lessor and Lessor's assignee(s)
as an additional insured, in such amounts with such companies and in such form
as is satisfactory to Lessor, with respect to injury to person or property
resulting from or based in any way upon or in any way connected with or relating
to the installation, use or alleged use, or operation of any or all of the
Equipment, or its location or condition.  Lessee shall deliver to Lessor, prior
to payment for any item of Equipment, satisfactory evidence of such insurance,
and shall further deliver evidence of renewal of each such policy not less than
30 days prior to expiration thereof.  Each such policy shall contain an
endorsement providing that the insurer will give Lessor not less than thirty
(30) days' prior written notice of the effective date of any alteration, change,
cancellation, or modification of such policy, or the failure by Lessee to timely
pay all required premiums, costs or charges with respect thereto.  Upon Lessor's
request, Lessee shall cause its insurance agent(s) to execute and deliver to
Lessor Loss Payable Clause Endorsement and Additional Insured Endorsement
(bodily injury and property damage liability insurance) forms provided to Lessee
by Lessor.  In case of the failure to procure or maintain such insurance, Lessor
shall have the right, but not the obligation, to obtain such insurance and any
premium paid by Lessor shall be immediately due and payable by Lessee to Lessor
as additional rent hereunder.  The maintenance of any policy or policies of
insurance pursuant to this Section shall not limit any obligation or liability
of Lessee pursuant to Section 7, Section 9 or any other provision of this Lease
and any Schedule hereto.

- --------------------------------------------------------------------------------
9. RISK OF LOSS

Until such time as the Equipment is returned and delivered to and accepted by
Lessor, pursuant to the terms of this Lease and any Schedule hereto, Lessee
hereby assumes and shall bear the entire risk of loss, damage, theft and
destruction of the Equipment, or any portion thereof, from any cause whatsoever,
commencing with delivery of such Equipment to Lessee ("Equipment Loss"). 
Without limitation of the foregoing, no Equipment Loss shall relieve Lessee in
any way from its obligations hereunder.  Lessee shall promptly notify Lessor in
writing of any Equipment Loss.  In the event of any such Equipment Loss, Lessee
shall; (a) in the event Lessor determines such Equipment to be repairable,
promptly place, at Lessee's expense, the Equipment in good repair, condition and
working order similar to that immediately prior to the Equipment Loss in
accordance with Seller's specifications and to the satisfaction of Lessor; or
(b) in the event of an actual or constructive total loss of any item of
Equipment, as Lessee and Lessor shall jointly determine: (i) promptly replace,
at Lessee's expense, the Equipment with like equipment of the same or a later
model with the same additions as the Equipment, and in good repair, condition
and working order in accordance with the Seller's specifications and to the
satisfaction of Lessor; or (ii) immediately pay to Lessor the amount specified
in the applicable Casualty Schedule made a part of this Lease or any Schedule
hereto or, in its absence, an amount equal to the total amount of applicable
unpaid rentals due and to become due hereunder during the term hereof, plus an
additional amount equal to the fair market value of the Equipment immediately
prior to the loss, theft, damage, or destruction, but in no event


<PAGE>

Master Lease Agreement
Page 7

shall the amount of such fair market value be less than twenty percent (20%) of
the actual cost of the Equipment.  In the event Lessee is required to repair or
replace any such item of Equipment pursuant to Subsections (a) or (b)(i) of the
preceding sentence, the insurance proceeds received by Lessor, if any, pursuant
to Section 8, after the use of such funds to pay any unpaid amounts then due
hereunder, shall be paid to Lessee or, if applicable, to a third party repairing
or replacing the Equipment upon Lessee's furnishing proof satisfactory to the
Lessor that such repair or replacement has been completed in a satisfactory
manner.  In the event Lessor elects option (b)(ii), Lessee shall be entitled to
a credit against the payment required by said Subsection in an amount equal to
such insurance proceeds actually received by Lessor pursuant to Section 8 on
account of such Equipment, and, upon payment by Lessee to Lessor of all of the
sums required pursuant to Subsection (b)(ii), the applicable Schedule shall
terminate with respect to such item of Equipment and Lessee shall be entitled to
whatever interest Lessor may have in such item "as is," "where is" and "with all
faults" in its then condition and location without warranties of any type
whatsoever, express or implied.

- --------------------------------------------------------------------------------
10. COVENANTS OF LESSEE

Lessee agrees that its obligations under this Lease and any Schedule hereto 
including, without limitation the obligation to pay rental, are irrevocable 
and absolute, shall not abate for any reason whatsoever (including any claims 
against Lessor), and shall continue in full force and effect regardless of 
any inability of Lessee to use the Equipment or any part thereof for any 
reason whatsoever including, without limitation, war, act of God, storms, 
governmental regulations, strike or other labor troubles, loss, damage, 
destruction, disrepair, obsolescence, failure of or delay in delivery of the 
Equipment, or failure of the Equipment to properly operate for any cause.  In 
the event of any alleged claim (including a claim which would otherwise be in 
the nature of a set-off) against Lessor, Lessee shall fully perform and pay 
its obligations hereunder (including all rents, without set-off or defense of 
any kind) and its only exclusive recourse against Lessor shall be by a 
separate action.  Lessee agrees to furnish promptly to Lessor the annual 
financial statements of Lessee (and of any guarantors of Lessee's performance 
under this Lease and any Schedule hereto), certified by independent certified 
public accountants, and such interim financial statements of Lessee as Lessor 
may reasonably require during the entire term of this Lease and any Schedule 
hereto.  Lessee, if requested, shall provide at Lessee's expense an Opinion 
of Counsel acceptable to Lessor affirming the covenants, representations and 
warranties of Lessee under this Lease and any Schedule hereto.

- --------------------------------------------------------------------------------
11. PERFORMANCE BY LESSOR OF LESSEE'S OBLIGATIONS

In case of the failure of Lessee to comply with any provision of this Lease and
any Schedule hereto, Lessor shall have the right, but not the obligation, to
effect such compliance on behalf of Lessee.  In such event, all reasonable costs
and expenses incurred by Lessor in effecting such compliance shall be
immediately paid by Lessee to Lessor as additional rental hereunder.

- --------------------------------------------------------------------------------
12. EVENTS OF DEFAULT

An event of default shall occur hereunder if Lessee or any Obligor ("Obligor"
shall include any guarantor or surety of any obligations of Lessee to Lessor
under this Lease and any Schedule hereto) (i) fails to pay any installment of
rent or other payment required hereunder when due; or (ii) attempts to or does
remove from the Premises (except a relocation with Lessor's consent as provided
in Section 5), sell, transfer, encumber, part with possession of, or sublet any
item of the Equipment; or (iii) shall suffer or have suffered, in the reasonable
judgment of Lessor, a material adverse change in its financial condition since
the date of the last financial statement submitted to Lessor, for which Lessee
is unable to satisfy, to Lessor's reasonable satisfaction, Lessor's demand for
assurances and as a result thereof Lessor deems itself to be insecure, or any of
the statements or other documents or information submitted at any time
heretofore or hereafter by Lessee or Obligor to Lessor has misstated or shall
misstate or has failed or shall fail to state a material fact; or (iv) breaches
or shall have breached any material representation or warranty made or given by
Lessee or Obligor in this Lease or in any other document


<PAGE>

Master Lease Agreement
Page 8

furnished to Lessor in connection herewith, or any such representation or
warranty shall be untrue or, by reason of failure to state a material fact or
otherwise, shall be misleading; or (v) fails to perform or observe any other
covenant, condition or agreement to be performed or observed by it hereunder,
and such failure or breach shall continue unremedied for a period of thirty (30)
days after the earlier of (a) the date on which Lessee obtains knowledge of such
failure or breach, or (b) the date on which notice thereof shall be given by
Lessor to Lessee; or (vi) shall become insolvent or bankrupt or make an
assignment for the benefit of creditors or consent to the appointment of a
trustee or receiver, or a trustee or receiver shall be appointed for a
substantial part of its property without its consent, or bankruptcy or
reorganization or insolvency proceeding shall be instituted by or against
Lessee; or (vii) conveys, sells, transfers or assigns substantially all of
Lessee's assets or ceases doing business as a going concern, or, if a
corporation, ceases to be in good standing or files a statement of intent to
dissolve, or abandons any or all of the Equipment; or (viii) shall be in
material breach of or in material default under any lease or other agreement at
any time executed with Lessor or any other lessor or with any lender to Lessee
after any applicable cure period, unless Lessee is in good faith disputing the
occurrence of such breach or default.

- --------------------------------------------------------------------------------
13. REMEDIES

Upon the occurrence of an event of default and at any time thereafter Lessor
may, in its sole discretion, do any one or more of the following: (i) upon
notice to Lessee, terminate this Lease as to the Equipment set forth in any one
or more or all of the Schedules; (ii) without affecting Lessor's title or right
to possession of the Equipment, declare due all rents and other amounts then
accrued and thereafter accruing under this Lease and any Schedule hereto for the
full term thereof including any amounts due upon expiration of the Minimum Lease
Term or extension thereof as set forth in any Schedule; (iii) require that
Lessee return all Equipment to Lessor in accordance with Section 3 hereof; (iv)
enter upon the Premises where such Equipment is located and take immediate
possession of and remove the same, all without liability to Lessor or its agents
for such entry, or for damage to property or otherwise; (v) sell any or all of
the Equipment at public or private sale, with or without notice to Lessee or
advertisement, or otherwise dispose of, hold, use, operate, lease to others or
keep idle such Equipment, all free and clear of any rights of Lessee therein and
without any duty to account to Lessee for such action or inaction or for any
proceeds with respect thereto; (vi) with or without cancelling this Lease,
recover from Lessee damages, in an amount equal to the sum of (a) all unpaid
rent and other amounts that became due and payable on, or prior to, the Default
Date, (b) the present value of all future rentals and other amounts described in
the Lease and not included in (a) above discounted to the Default Date at a rate
equal to the discount rate of the Federal Reserve Bank of Chicago as of the
Commencement Date of the Lease with respect to each Schedule (which discount
rate, Lessee agrees is a commercially reasonable rate which takes into account
the facts and circumstances at the time such Schedule commenced), (c) all costs
and expenses incurred by Lessor in enforcing Lessor's rights under this Lease,
including but not limited to, costs of repossession, recovery, storage, repair,
sale, re-lease and reasonable attorneys' fees, (d) the estimated residual value
of the Equipment as of the expiration of the Lease as reasonably determined by
Lessor, (e) any indemnity amount payable to Lessor; (vii) refuse to deliver to
Lessee the Equipment or such portion thereof not delivered theretofore; (viii)
exercise any other right or remedy which may be available to it under the
Uniform Commercial Code or any other applicable law or proceed by appropriate
court action, without affecting Lessor's title or right to possession of the
Equipment, to enforce the terms hereof or to recover damages for the breach
hereof or to rescind this Lease and any Schedule hereto as to any or all
Equipment.  In addition, Lessee shall be liable for all reasonable legal fees
and other costs and expenses resulting from the foregoing or the exercise of
Lessor's remedies, including placing any Equipment in the condition required by
Section 3. No remedy referred to in this Section is intended to be exclusive,
but each shall be cumulative and in addition to any other remedy referred to
above or otherwise available to Lessor at law or in equity.  No express or
implied waiver by Lessor of any default shall constitute a waiver of any other

Dear Mr. Nagle,

    Regarding the maintenance of the PSC, inc. dielectric heater Serial No. 672
Model 80-WM currently installed at your West Memphis, Arkansas facility, I would
like to offer the following.

    Sol Sailes and Kent Huntzinger, currently employed by Stericycle of

inc. for this equipment.

    The information Sol and Kent acquired during the training period should
qualify them to keep the equipment in good running condition and in line with
PSC, inc. specifications.

    Should you require further assistance, please do not hesitate to call.

                                       Very truly yours,

                                       PSC, inc.

Attention: [ * ]
     Director Presidente

                              INTERIM AGREEMENT

Dear Mr. Fernandes:

     In connection with recent discussions between Stericycle, Inc.
("Stericycle") and [ * ] regarding a proposed comprehensive Agreement for
Technical and Industrial Cooperation (the "Definitive Agreement") for the use of
Stericycle's proprietary systems and technology for medical waste management in
Brazil, we hereby set forth our agreement with respect to short-term cooperation
(the "Interim Agreement"), subject to formal approval of the parties' Boards of
Directors.

     1.   INTRODUCTION. Stericycle owns (a) certain proprietary medical waste
treatment and recycling technology; (b) certain proprietary know-how respecting
operations, sales, marketing and regulatory compliance, (c) certain patents,
trademarks, and other proprietary intellectual property, and (d) certain
proprietary programs, systems, literature and training methods ((a) - (d)
collectively referred to as the "Stericycle Proprietary Rights"). [ * ] are
experienced and knowledgeable engineers, developers and operators in the waste
management industry in South America. Stericycle and [ * ] have reached an
Interim Agreement whereby [ * ] may utilize the Stericycle Proprietary Rights in
Sao Paulo and Rio de Janeiro Brazil in order to participate in contract
procurement activities.

     2.   LICENSE. Stericycle shall grant [ * ] an exclusive license to use
Stericycle Proprietary Rights in Sao Paulo and Rio de Janeiro Brazil, including
the use of the trademark "Stericycle" during the term of the Interim Agreement.
The license shall not include sublicensing rights.

     3.   TERRITORY. The Interim Agreement grants rights only in Sao Paulo and
Rio de Janeiro Brazil. The parties contemplate that the Definitive Agreement, if
and when effective, will grant exclusive rights to [ * ] in Brazil. The parties
will discuss in good faith the expansion of the territory to include the
countries of Argentina and Chile.

     4.   TERM. The term of the Interim Agreement shall be for [ * ].

     5.   DEFINITIVE AGREEMENT. The parties agree to negotiate in good faith the
terms and conditions of the Definitive Agreement within [ * ] from the date
hereof. If no definitive Agreement has been entered into within the aforesaid
[ * ] period, except for the provisions of paragraph 8 hereof relating to
confidentiality which shall continue in effect, (a) this Interim Agreement
shall expire and be

*    omitted; filed separately with the Commission.

of no further effect, and (b) [ * ] shall no longer have any license or other 
rights to the Stericycle Proprietary Rights, and shall return any documents 
or other embodiment of the information comprising such Stericycle Proprietary 
Rights to Stericycle. Upon the effectiveness of the Definitive Agreement, 
Stericycle will commit to provide equipment capable of processing [ * ] of 
medical waste per 24 hour day, in a processing facility built in an 
appropriate [ * ] supplied building and site for a price not to exceed [ * ]
U.S. net of freight, duties and taxes. [ * ] shall also pay royalties to 
Stericycle not to exceed [ * ] per pound of medical waste. These sums are 
subject to revision based upon final plant configuration and range of 
services offered.

     6.   INTERIM AGREEMENT.

     (a)  During the terms of this Interim Agreement Stericycle will:

          (i)     provide [ * ] with access to Stericycle Proprietary Rights;

          (ii)    provide [ * ] with executive support, on request, in support
                  of the establishment of the Stericycle concept in Brazil and
                  will reimburse Stericycle for expenses incurred in this
                  regard;

          (iii)   provide [ * ] with facility design, operational cost, data and
                  strategies for Stericycle treatment and recycling
                  technologies;

          (iv)    provide [ * ] and its potential clients access to Stericycle's
                  facilities in the US;

          (v)     negotiate exclusively with [ * ] for medical waste management
                  opportunities in Brazil.

     (b)  During the term of this Interim Agreement [ * ] will:

          (i)     aggressively pursue medical waste treatment opportunities in
                  the Sao Paulo and Rio de Janeiro market of Brazil;

          (ii)    develop a plan for product offerings in these markets
                  utilizing Stericycle's systems and proprietary information;
                  and

          (iii)   negotiate exclusively with Stericycle for medical waste
                  management opportunities in Brazil.

     7.   PAYMENTS. For the activities listed in paragraph 6(a)(i) - (iv) above,
[ * ] will pay Stericycle [ * ] U.S. In addition, [ * ] will pay Stericycle
[ * ] U.S. in consideration of Stericycle's commitment in paragraph 6(a)(v)
above, to deal exclusively with [ * ] during the term of this Interim Agreement
for medical waste management opportunities in Brazil. Such payments shall be
made in four monthly payments of [ * ] on July 1, 1996; [ * ] on August 1, 1996;
[ * ] on September 1, 1996; and [ * ] on October 1, 1996.

     8.   CONFIDENTIALITY. Stericycle and [ * ] recognize the highly
confidential nature of their respective proprietary information (and in this
regard, all information contained in the definition of Stericycle Proprietary
Rights shall be proprietary information of Stericycle). Accordingly, Stericycle
and [ * ] for themselves, their affiliates, officers, directors and agents
hereby agree that they will hold in confidence, not disclose to others and not
use except for purposes of this Interim Agreement and the Definitive Agreement
described herein (if and when effective), any and all proprietary information
disclosed to it by the other party. The provisions of this paragraph shall not
apply to any proprietary information which (a) is or later becomes publicly
known under circumstances involving no breach of disagreement by the receiving
party; (b) was already known to the receiving party (other than by previous
disclosure to the receiving party by the disclosing party) as evidenced by the
receiving party's records at the time of receipt of such proprietary information
from the disclosing party; or (c) is lawfully made available to the receiving
party by a third party. Both parties recognize that money damages alone would
not be an adequate remedy for the breach of this confidentiality provision, and
therefore agree that, in the event of the breach of this provision by one party,
the other party shall be entitled to injunctive relief or its functional
equivalent under Brazilian law, prohibiting the breaching party from engaging in
any business activities which employ the proprietary information of the other.

     9.   FORM. The parties may reconsider the form of business relationship and
characterization of fees to maximize the benefit of local business and tax laws.

     10.  DISPUTE RESOLUTION. The parties agree that all disputes arising under
this Interim Agreement will be resolved by binding arbitration before the
American Arbitration Association using its commercial arbitration rules and
applying the substantive laws of the State of Illinois.

     Please indicate your agreement to the terms of this Interim Agreement by
signing and returning a copy to the undersigned.

                                   Stericycle, Inc.
