(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 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.

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 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.

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.

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.

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. 6.

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 not all or any part of such Obligations are otherwise then due and payable.

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. 7.

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.

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. 8.

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.

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 Stericycle, Inc. August 4, 1993 Page 2 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.

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

ORDER M. V. G. NO. 1657 PAGE 3 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. DATED at Olympia, Washington and effective this 15th day of September 1993. WASHINGTON UTILITIES AND TRANSPORTATION COMMISSION /s/Richard D. Casad RICHARD D. CASAD, Commissioner /s/Richard Hemstad RICHARD HEMSTAD, Commissioner

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.

[LETTERHEAD] AUGUST 10, 1993 Ms. Mary Ann Boyle VIA FAX Corporate Accounting (708) 945-6583 Stericycle, Inc. 1419 Lake Cook Road Deerfield, Illinois 20015 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.

Ms. Mary Ann Boyle August 10, 1993 Page 2 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.

Ms. Mary Ann Boyle August 10, 1993 Page 3 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.

SCHEDULE 10.1(h) - COMPLIANCE WITH LAW; PERMITS 1. See Schedule 10.1(g), Item 2.

SCHEDULE 10.1(k) - INTELLECTUAL PROPERTY 1. Stericycle's use of the Intellectual Property is subject to restrictions under applicable laws (including common law) and regulations regarding patents, trademarks and other items of Intellectual Property. 2. SAGE, Inc. has joint ownership in certain Stericycle assets which have been or may be developed by Stericycle pursuant to Section 8 of that certain letter agreement dated November 11, 1992 between SAGE, Inc. and Stericycle. 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.

AGREEMENT THIS AGREEMENT is made and entered into on this 6th day of May, 1994, by and between SAGE PRODUCTS, INC., an Illinois corporation ("Sage") and STERICYCLE, INC., an Illinois corporation ("Stericycle"). WITNESSETH: WHEREAS, Sage and Stericycle desire to develop a process which will generate a constant source of polyolefin, a plastic product consisting substantially of polypropylene with traces of polyethylene and polystyrene and other olefins, from post consumer medical waste (the "Product") for use by Sage in the manufacture of its line of health care products; WHEREAS, pursuant to the terms of that certain Letter Agreement dated November 11, 1992 (the "Letter Agreement"), Sage and Stericycle have previously agreed to jointly develop a process which will facilitate the reclamation of the Product from post consumer medical waste for use by Sage in the manufacture of its line of health care products (the "Process"); WHEREAS, Sage and Stericycle have previously expended monies pursuant to the development of the Process; WHEREAS, Sage has agreed to make a payment of up to[ * ] to Stericycle, which payment will be applied towards [ * ] the * Omitted; filed separately with the Commission

total installed cost of that certain equipment which is necessary for the further development of the Process, as that certain Equipment is described in Exhibit A (the "Equipment"); WHEREAS, from and after the time that development of the Process is complete, Sage has agreed to purchase from Stericycle, and Stericycle has agreed to sell to Sage, the Product that is reclaimed from post-consumer medical waste by application of the Process; and WHEREAS, Sage and Stericycle have agreed that Sage's payment of additional monies to Stericycle for the development of the Process and the purchase and sale of the resulting product will best be effectuated pursuant to the terms and provisions set forth herein; NOW, THEREFORE, in consideration of the mutual promises and covenants contained herein, and for other good and valuable consideration, the adequacy and sufficiency of which is hereby acknowledged, Sage and Stericycle agree as follows: 1. DEVELOPMENT PERIOD. A. EQUIPMENT. As the Equipment is installed and invoiced, Sage agrees to make a payment of up to [ * ] (the "Cash Payment") to Stericycle. Stericycle agrees to apply the Cash Payment towards [ * ] the cost of purchasing the Equipment (the "Project Cost"). Stericycle further agrees that it will apply up to [ * ] of cash, or assets having a net book value equivalent to [ * ] toward the * Omitted; filed separately with the Commission 2

Project Cost. The Equipment is described on Schedule "A" attached hereto, which 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. * Omitted; filed separately with the Commission 3

(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 4

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

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

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

(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

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. * Omitted; filed separately with the Commission 9

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

Monthly Net Sales Royalty Percentage 1. [ * ] [ * ] 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.

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.

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.

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.

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 maintenance service agreements to the heating, ventilation and air conditioning equipment and controls servicing the Premises or must contract with a landlord approved maintenance firm for same. Tenant shall pay all 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.

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. 4.3 LATE PAYMENT. Tenant's failure to make any rental or other payment required of Tenant hereunder within ten (10) days of the due date therefor shall automatically result in the imposition of a service charge for such late payment 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. 5

Such termination shall become effective as of the date of the damage.

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.

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

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

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.

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. 5

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

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

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'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.

MISCELLANEOUS. For purposes of this Lease, the term "Rent" as used herein shall mean and include all amounts payable by Lessee to Lessor hereunder.

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.

The Equipment leased hereunder is as follows: New/Used Quantity Model Number Serial No. Equipment and Description Location Purchase Price SEE ATTACHED SCHEDULE A TOTAL: $ 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.

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

agreeable to Lessor and Lessee.

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.

LINC VENTURE LEASE PARTNERS II, L.P. LINC Venture Lease Partners II, L.P. MASTER LEASE AGREEMENT 303 East Wacker Drive This is a counterpart number Chicago, Illinois 60601 2 of 2 serially (312) 467-5500 numbered, manually executed counterparts. STERICYCLE, INC. and 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

Master Lease Agreement Page 2 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

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

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

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

Master Lease Agreement Page 6 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.

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.

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.

To the extent not prohibited by applicable law, Lessee

[LETTERHEAD] June 28, 1996 [ * ] 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.

Mr. [ * ] June 28, 1996 Page 2 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. * omitted; filed separately with the Commission

Mr. [ * ] June 28, 1996 Page 3 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. By: /s/ Anthony J.
