Item 2. Acquisition or Disposition of Assets. Purchase of CSD Assets On September 10, 2002, Clean Harbors, Inc. and certain of its wholly-owned subsidiaries (collectively, the "Company") purchased the assets of the Chemical Services Division (the "CSD") of Safety-Kleen Services, Inc. (the "Seller"). The sale included the operating assets of 56 of the Seller's subsidiaries in the United States and the stock of five of the Seller's subsidiaries in Canada (the "CSD Canadian Subsidiaries"). The sale was made pursuant to a sales order issued on June 18, 2002 by the Bankruptcy Court for the District of Delaware as part of the proceedings under Chapter 11 of the Bankruptcy Code in which Safety-Kleen Corp. ("Safety-Kleen") and 73 of its domestic subsidiaries (including the Seller) have been operating since June 2000 as debtors in possession. The sales order authorized the sale of the assets of the CSD to the Company free and clear of all liens, claims, encumbrances and interests except for certain liabilities and obligations assumed by the Company as part of the purchase price. Although the sale closed on September 10, the Company and the Seller have agreed that for tax and accounting purposes the sale shall be deemed to have occurred at 12:01 a.m. on Saturday, September 7. The assets of the CSD (including the assets of the CSD Canadian Subsidiaries) acquired by the Company consist primarily of 50 hazardous waste treatment and disposal facilities including, among others, 21 service centers, six wastewater treatment facilities, nine landfills and four incinerators. Such facilities are located in 30 states, Puerto Rico and six Canadian provinces. The most significant of such facilities include a landfill in Buttonwillow, California with approximately 11.3 million cubic yards of remaining capacity, a landfill in Westmorland, California with approximately 2.8 million cubic yards of remaining capacity, a landfill in Lambton, Ontario with approximately 1.9 million cubic yards of remaining capacity which is the largest of the total of three hazardous waste landfills in Canada, three rotary incinerators in Deer Park, Texas which are collectively the largest capacity hazardous waste incinerator in the United States, and an incinerator in Lampton, Ontario which is the largest capacity hazardous waste incinerator in Canada. The acquired assets do not include Safety-Kleen's Pinewood landfill in South Carolina, which Safety-Kleen had previously operated as part of the CSD. The addition of the CSD assets broaden the Company's geographic reach, particularly in the West Coast and Southwest regions and in Canada and Mexico and make the Company the largest operator of hazardous waste treatment and disposal facilities in North America. The combined Company is expected to have annualized revenue of approximately $750 million, approximately 4,400 employees, and approximately 38,000 customers including a sizable majority of the Fortune 500. In accordance with the Acquisition Agreement between the Seller and the Company dated February 22, 2002, as amended through September 6, 2002, the Company purchased the assets of the CSD for $34.3 million in cash and the assumption of certain environmental liabilities valued at approximately $265 million. The cash portion of the purchase price is subject to adjustment based upon the level of working capital of the CSD as of the closing date, as such level will be determined subsequent to the closing. In addition to the cash purchase price paid to the Seller, the Company also paid an aggregate of $209,000 of cure costs (one-half of the total -2-

cure cots) to third parties in connection with the Company's assumption of certain of the CSD's unexpired contracts and leases which the Company had elected to assume. Prior to the sale of the CSD assets to the Company, the largest single customer of the CSD had been Safety-Kleen's Branch Sales and Services Division (the "BSSD"), which primarily serves as a "front-end" collection agent for approximately 400,000 clients in the industrial and commercial parts cleaning and hazardous/non-hazardous waste market, particularly with regard to waste fuel and solvent recovery and recycling. In connection with the Company's purchase of the CSD assets, the Company and the Seller entered into a Master Waste Disposal Agreement which will ensure, during the three-year term of the Agreement, that the BSSD will continue to be able to rely upon the Company (which now owns the facilities of the CSD) to provide hazardous waste treatment and disposal services and that the Company will continue to have the BSSD as a major customer. Under Section 5.15 of the Acquisition Agreement as amended, the Company and the Seller have agreed to certain non-competition and non-solicitation provisions which are intended to separate the respective businesses of the Company and the BSSD for a period of three years after the closing. Under such Section, the Company and the Seller have also agreed during such period not to recruit or otherwise solicit, with certain exceptions, any of their respective employees to leave such employment. Related Financings In order to finance the cash portion of the purchase price for the CSD assets, refinance all of the Company's previously outstanding debt, provide cash collateral for letters of credit to support the financial assurances which the Company must provide to governmental entities for the Company's licensed hazardous waste facilities, pay transaction costs and provide for adequate future working capital, the Company raised $280 million of total financings (which amount includes $20 million of additional loans under the Ableco Financing Agreement described below which closed within three days after the initial closing of such Agreement on September 10, 2002). The $280 million of total financings consist of a $100 million three-year revolving credit facility (the "Revolving Credit Facility"), $115 million of three-year non-amortizing term loans (the "Senior Loans"), $40 million of five-year non-amortizing subordinated loans (the "Subordinated Loans"), and $25 million of Series C convertible preferred stock ("Series C Preferred Stock"). In addition to such financings, the Company has established a letter of credit facility (the "L/C Facility") under which the Company may obtain up to $100 million of letters of credit by providing cash collateral equal to 103% of the amount of such outstanding letter of credit. The Company now has approximately $155 million of outstanding debt and $50 million of restricted cash pledged or reserved as collateral for letters of credit. Upon the issuance of additional letters of credit in March 2003 to support financial assurances, the outstanding debt will increase to approximately $200 million and the restricted cash will increase to approximately $100 million. The principal terms of the Revolving Credit Facility, the Senior Loans, the Subordinated Loans, the Series C Preferred Stock and the L/C Facility are as follows: -3-

Revolving Credit Facility. The Revolving Credit Facility was established under a Loan and Security Agreement dated September 6, 2002 between the Company and Congress Financial Corporation (New England) as Lender and as Agent for the other Lenders thereunder. The Revolving Credit Agreement allows the Company to borrow up to $100 million in cash and letters of credit, based upon a formula of eligible accounts receivable. This total is separated into two lines of credit, namely a line for the CSD Canadian Subsidiaries of $20 million in Canadian dollars and a line for the Company and its US subsidiaries equal to $100 million in US dollars less the then conversion value of the Canadian line. Letters of credit outstanding at any one time under the Revolving Credit Facility may not exceed $20 million. The Revolving Credit Facility allows for up to 80% of the outstanding balance of the loans to bear interest at an annual rate of LIBOR plus 3.0%, with the balance at prime. The Revolving Credit Agreement requires the Company to pay an unused line fee of 0.25% per annum on the unused portion of the revolving credit. The Company's obligations under the Revolving Credit Facility are secured by a first security interest in the Company's accounts receivable and a second security interest in substantially all of the Company's other assets (exclusive of real estate, rolling stock and cash collateral provided by the Company to the issuer of the letters of credit under the L/C Facility). The Revolving Credit Facility provides for certain covenants including, among others, requiring the Company to maintain (i) consolidated annualized or rolling four quarters earnings before interest, income taxes, depreciation and amortization ("EBITDA") of not less than $56 million for purposes of calculating the annualized EBITDA as of the completion of the fiscal quarter ending December 31, 2002 and increasing in approximately equal quarterly increments to not less than $170 million for purposes of calculating the rolling four quarters EBITDA as of the completion of the fiscal quarter ending December 31, 2007, and (ii) an annualized or four quarters rolling fixed charge coverage ratio of not less than 0.65 to 1.0 for the fiscal quarter ending December 31, 2002 and increasing in approximately equal quarterly increments to not less than 1.5 to 1.0 for each fiscal quarter ending after December 31, 2004. The covenants generally provide for annualized, rather than rolling four quarters, calculations for each of the first four fiscal quarters commencing on and after October 1, 2002 because, while the closing on September 10, 2002 of the financings related to the CSD asset acquisition significantly increased the Company's level of total outstanding debt and interest costs, the anticipated increases in the Company's EBITDA resulting from the acquisition commenced only with the acquisition and are not reflected in the Company's results of operations for prior periods of 2002. Senior Loans and Subordinated Loans. Both the Senior Loans and the Subordinated Loans were provided under a Financing Agreement dated September 6, 2002 (the "Ableco Financing Agreement") between the Company, the Lenders thereunder and Ableco Finance LLC as Agent for the Lenders. The Senior Loans bear interest at an annual rate of LIBOR plus 7.25%, and the Subordinated Loans bear interest at an annual rate of 22.0% (of which up to one-half may be either paid in cash or in kind at the Company's option). The Senior Loans and the Subordinated Loans are secured by a first security or mortgage interest in substantially all of the Company's assets, except for second security interests in the Company's accounts receivable in which the Agent under the Revolving Credit Facility has a first security interest and the cash collateral provided by the Company to the issuer -4-

of letters of credit under the L/C Facility in which such issuer has a first security interest. The Ableco Financing Agreement provides for certain covenants including, among others, requiring the Company to maintain (i) consolidated annualized or rolling four quarters EBITDA of not less than $56 million for purposes of calculating the annualized EBITDA as of the completion of the fiscal quarter ending December 31, 2002 and increasing in approximately equal quarterly increments to not less than $170 million for purposes of calculating the rolling four quarters EBITDA as of the completion of the fiscal quarter ending December 31, 2007, (ii) an annualized or rolling four quarters fixed charge coverage ratio of not less than 0.65 to 1.0 for the fiscal quarter ending December 31, 2002 and increasing in approximately equal quarterly increments to not less than 1.5 to 1.0 for each fiscal quarter ending after December 31, 2004, and (iii) a ratio of consolidated funded indebtedness to either consolidated annualized or rolling four quarters EBITDA of not more than 3.5 to l.0 for the fiscal quarter ending December 31, 2002 and decreasing in approximately equal quarterly increments to not more than 1.5 to l.0 for each fiscal quarter ending on or after December 31, 2004. Series C Preferred Stock. The Series C Preferred Stock was issued by the Company on September 10, 2002 to certain affiliates of the Lenders under the Ableco Financing Agreement pursuant to a Securities Purchase Agreement dated September 6, 2002 between the Company and such investors. The Series C Preferred Stock provides for dividends at an annual rate of 6% (which after the first year will accrue and compound), will be mandatorily redeemable after seven years, and (together with accrued dividends thereon) will be convertible at the holder's option into shares of the Company's common stock. The conversion price will initially be $10.50 per share of common stock, subject to customary adjustments for antidilution and potential reset to $8.00 per share if both (i) the Company's Consolidated EBITDA for the year ending December 31, 2003 is less than $115 million and (ii) the average trading price for the Company's common stock for the month of December 2003 is less than $27.50. In no event, however, will the Company be obligated to issue more shares of common stock upon the conversion of the Series C Preferred Stock than is permitted under the rules and regulations of The Nasdaq Stock Market. Accordingly, unless the Company's common stockholders shall in the future approve the issuance of a greater number of common shares upon the conversion of the preferred shares, the maximum number of common shares which may be issued upon conversion of the Series C Preferred Stock will be limited to approximately 2,380,953 shares based upon the $25 million purchase price for the Series C Preferred Stock and the initial conversion price of $10.50 per share. To the extent (if any) that the purchase price of the Series C Preferred Shares, plus the amount of any accrued dividends, would otherwise be convertible into more than the number of shares permitted under NASDAQ rules, and the Company's common stockholders shall not have approved the issuance of the excess common shares, the Company will be obligated to issue only that approximately 2,380,953 common shares and to pay in cash to the holders of the Series C Preferred Stock the then market value of the additional common shares which can not be issued because of the foregoing limitation. The terms of the Series C Preferred Stock provide for certain covenants for the benefit of the holders thereof. Among other matters, without the approval of the holders of a majority of the outstanding shares of Series C Preferred Stock, the Company shall not be permitted to (i) pay -5-

cash dividends upon its outstanding common stock, (ii) incur indebtedness in excess of indebtedness under the Revolving Credit Facility, the Ableco Financing Agreement, the L/C Facility and certain other forms of permitted indebtedness, (ii) merge or make material acquisitions or dispositions with certain exceptions, (iii) create new classes of preferred stock, or (iv) amend its charter in any manner which would have an adverse effect upon the holders of the Series C Preferred Stock. Should the Company fail to comply with these covenants and fail to cure the default within 30 days of notice from the holders of the Series C Preferred Stock, (i) the dividend rate on the Series C Preferred Stock would increase to 12% per annum until the later of (A) the six-month anniversary of the covenant default or (B) the date on which such covenant default is cured and (ii) the conversion price for the Series C Preferred Stock would decrease (subject to potential subsequent adjustments to the conversion price as described above) to an amount equal to either (A) $8.00 per share of common stock if the conversion price in effect on the date of the covenant default is greater than $8.00 per share of common stock, or (B) 90% of the conversion price in effect on the date of the covenant default if the conversion price in effect on the date of the covenant default is less than or equal to $8.00 per share of common stock. L/C Facility. The L/C Facility was established under a Letter of Credit Facility Agreement dated September 6, 2002 between the Company and Fleet National Bank ("Fleet"). The L/C Facility Agreement provides that Fleet will issue up to $100 million of letters of credit at the Company's request provided that the Company provides cash collateral equal to 103% of the amount of the outstanding letters of credit (with the Company retaining the interest earned on such cash collateral). The Company will pay Fleet's customary charges for the issuance of such letters of credit plus an annual fee equal to 0.3% of the outstanding amount thereof. The term of the L/C Facility will expire on September 9, 2005. Item 7. Financial Statements and Exhibits. (a) Financial statements of businesses acquired. Attached are audited balance sheets of the CSD, together with notes thereto and a report thereon of Arthur Andersen LLP, as at the completion of each of Safety-Kleen's three most recently completed fiscal years ended August 31, 2001, 2000, and 1999. For reasons discussed in Note 2 to such audited balance sheets of the CSD, Safety-Kleen (which has been operating under Chapter 11 of the Bankruptcy Code since June 2000) has not been able to deliver to the Company any audited statements of income or cash flows of the CSD or related footnotes. Accordingly, the Company is able to file with this Report the audited balance sheets of the CSD and will be able to file, within 60 days hereafter by amendment to this Report, an unaudited pro forma combined balance sheet of the Company and the CSD as at the completion of the Company's most recent fiscal year on December 31, 2001, but the Company will not be able to file any audited statements of income or cash flows of the CSD or an unaudited pro forma combined statement of operations for the Company and the CSD based thereon. By letter dated February 22, 2002, the Commission's staff has provided, subject to the terms described therein, "no-action" relief to the Company with respect to the Company's inability to file audited statements of income or cash flows of the CSD or an unaudited pro forma combined statement of operations of the Company and the CSD based thereon. (b) Pro forma financial information. See Item 7(a) above. (c) Exhibits. -6-

Chemical Services Division of Safety-Kleen Corp. (Debtors-in-Possession As of June 9, 2000) Combined Balance Sheets At August 31, 2001, 2000 and 1999 Together with Report of Independent Public Accountants

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To Safety-Kleen Corp.: We have audited the accompanying combined balance sheets of the Chemical Services Division of Safety-Kleen Corp., (the "Company" - see Note 1), at August 31, 2001, 2000, and 1999. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the balance sheets are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the balance sheets. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the combined balance sheets referred to above present fairly, in all material respects, the financial position of the Chemical Services Division of Safety-Kleen Corp, at August 31, 2001, 2000, and 1999, in conformity with accounting principles generally accepted in the United States. As discussed in Note 2, the Company was unable to prepare and present combined statement of operations and cash flow data for the three years ended August 31, 2001, in accordance with accounting principles generally accepted in the United States. Therefore, we are unable to express, and we do not express, an opinion on the Company's statements of operations, cash flows or changes in net parent company investment for the three years ended August 31, 2001. The accompanying combined balance sheets have been prepared assuming that the Company will continue as a going concern. As discussed in Notes 1 and 2 to the combined balance sheets, on June 9, 2000, Safety-Kleen Corp. and certain of its subsidiaries (including all of the Company's domestic operations), collectively referred to as the "Debtors", each filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code and continue to operate their respective businesses as debtors-in-possession. The Debtors' plans in regard to these matters, including their intent to file a plan of reorganization acceptable to the Bankruptcy Court and the creditors, are also described in Notes 1 and 2. These matters, among others, raise substantial doubt about the Company's ability to continue as a going concern. In the event a plan of reorganization is accepted, continuation of the business thereafter is dependent on the Company's ability to achieve successful future operations. The accompanying combined balance sheets do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

CHEMICAL SERVICES DIVISION OF SAFETY-KLEEN CORP. NOTES TO COMBINED BALANCE SHEETS 1. BUSINESS, ORGANIZATION AND BANKRUPTCY Organization and Safety-Kleen Safety-Kleen Corp. was incorporated in Delaware in 1978 as Rollins Environmental Services, Inc. ("Rollins"), later changed its name to Laidlaw Environmental Services, Inc. ("LESI") and subsequently changed its name to Safety-Kleen Corp. On May 15, 1997, pursuant to a stock purchase agreement among Rollins, Laidlaw Inc., a Canadian corporation ("Laidlaw"), and its subsidiary, Laidlaw Transportation Inc. ("LTI"), Rollins acquired the hazardous and industrial waste operations of Laidlaw (the "Rollins Acquisition"). As a result of the Rollins Acquisition, Laidlaw owned 67% of the issued and outstanding common shares of LESI. Accordingly, the business combination was accounted for as a reverse acquisition using the purchase method of accounting, with Rollins being treated as the acquired company. Coincident with the closing of the Rollins Acquisition, the continuing legal entity changed its name from Rollins Environmental Services, Inc. to Laidlaw Environmental Services, Inc. On May 26, 1998, LESI completed the acquisition of the former Safety-Kleen Corp. ("Old Safety-Kleen"). Effective July 1, 1998, LESI began doing business as Safety-Kleen Corp. and its stock began trading on the New York Stock Exchange ("NYSE") under the name Safety-Kleen Corp. and the ticker symbol SK. The stock was suspended from trading on the NYSE and the Pacific Exchange, Inc. ("PCX") on June 12, 2000 and removed from listing and registration on the NYSE on July 20, 2000, and the PCX on September 29, 2000. The stock now trades over the counter as SKLNQ. Safety-Kleen Corp. through its subsidiaries (collectively, "Safety-Kleen"), provides a range of services designed to collect, transport, process, recycle or dispose of hazardous and non-hazardous industrial and commercial waste streams. Safety-Kleen provides these services through its two primary operating divisions - - the Chemical Services Division and the Branch Sales and Service Division ("BSSD"). Support services consisting primarily of legal, accounting, finance and information technology are provided to the operating divisions through Safety Kleen's corporate division ("Corporate"). As further discussed in Note 2, certain assets and liabilities in the Combined Balance Sheets include allocations, primarily from Corporate. Chemical Services Division The accompanying Combined Balance Sheets of the Chemical Services Division (the "Company") at August 31, 2001, 2000 and 1999, have been presented on a carve-out basis. The Company operates approximately 100 primary and satellite locations from which it provides waste management services in North America. The services offered consist primarily of the collection, treatment and disposal of a wide variety of hazardous or non-hazardous liquid and solid wastes, in drum, tanker or roll-off containers from customer locations. The Company provides final treatment and disposal services for hazardous and non-hazardous wastes, through the Company's network of thermal destruction incinerators, landfills and wastewater treatment facilities, in certain instances after accumulating and treating waste at service centers. The Company is comprised of specific internal business units of Safety-Kleen, included within certain domestic, Canadian and Mexican subsidiaries. On February 22, 2002, Safety-Kleen entered into a definitive agreement with Clean Harbors, Inc. ("Clean Harbors") to sell certain net assets of Safety-Kleen including certain net assets of the Company. Pursuant to the terms of the agreement, Clean Harbors would purchase the defined net assets, excluding Safety-Kleen (Pinewood), Inc. (the "Pinewood Facility") and certain allocated assets and liabilities of the Company, from Safety-Kleen for $46.3 million in cash, subject to defined working capital adjustments, and the assumption of certain liabilities, including environmental liabilities. The book value of the net assets to be sold, net of the liabilities to be assumed, at August 31, 2001 was in excess of $300 million. On March 8, 2002, the Bankruptcy Court approved the bidding and auction procedures for the sale. Pursuant to the bidding procedures, all qualified bidders interested in purchasing some of all of the aforementioned net assets must submit an alternative qualified bid on or before May 20, 2002. There can be no assurance that the Bankruptcy Court and/or the various regulatory agencies will approve the sale to Clean Harbors or an alternative purchaser, or that Safety-Kleen will be able to complete the sale. Safety-Kleen Bankruptcy On June 9, 2000, Safety-Kleen Corp. and 73 of its domestic subsidiaries (collectively, the "Debtors"), including all of the Company's domestic operations, filed voluntary petitions for relief (the "Chapter 11 Cases") under Chapter 11 of the United States Bankruptcy Code, 11 U.S.C. (SS) 101-1330, as amended (the "Bankruptcy Code") in the United States Bankruptcy Court for the District of Delaware (the "Bankruptcy Court"). The Chapter 11 Cases are being jointly administered for procedural purposes only before the Bankruptcy Court under case No. 00-2303 (PJW). Excluded from the filing were certain of Safety-Kleen Corp.'s non wholly-owned domestic subsidiaries and all Safety-Kleen Corp.'s indirect foreign subsidiaries, including all of the Company's Canadian operations. See Note 15 for Condensed Combined Balance Sheets of entities in bankruptcy. 4

The Debtors remain in possession of their properties and assets, and the management of the Debtors continues to operate their respective businesses as debtors-in-possession under Sections 1107 and 1108 of the Bankruptcy Code. As debtors-in-possession, the Debtors are authorized to manage their properties and operate their businesses, but may not engage in transactions outside the ordinary course of business without the approval of the Bankruptcy Court. Under Section 365 of the Bankruptcy Code, subject to the approval of the Bankruptcy Court, the Debtors may assume or reject executory contracts and unexpired leases. Parties affected by these rejections may file proofs of claim with the Bankruptcy Court in accordance with the reorganization process. Claims for damages resulting from the rejection of executory contracts or unexpired leases will be subject to separate bar dates, generally thirty days after entry of the order approving the rejection. At various times since the commencement of the Chapter 11 Cases, the Bankruptcy Court has approved the Debtors' requests to reject certain contracts or leases that were deemed burdensome or of no further value to the Company. As of April 11, 2002, the Debtors had not yet completed their review of all contracts and leases for assumption or rejection, but ultimately will assume or reject all such contracts and leases. The Debtors have until the confirmation of a plan or plans of reorganization to assume or reject executory contracts, nonresidential real property leases, and certain other leases. The Debtors cannot presently determine or reasonably predict the ultimate liability that may result from rejecting such contracts or leases or from the filings of rejection damage claims, but such rejections could result in additional liabilities subject to compromise (see Note 8). Consummation of a plan or plans of reorganization is the principal objective of the Chapter 11 Cases. A plan of reorganization sets forth the means for satisfying claims against and interests in the Debtors, including the liabilities subject to compromise. Generally, pre-petition liabilities are subject to settlement under such a plan or plans of reorganization, which must be voted upon by creditors and equity holders and approved by the Bankruptcy Court. The Debtors have retained Lazard Freres & Co. LLC, an investment bank, as corporate restructuring advisor to assist them in formulating and negotiating a plan or plans of reorganization for the Debtors. Although the Debtors expect to file a reorganization plan or plans as soon as reasonably possible, there can be no assurance that a reorganization plan or plans will be proposed by the Debtors or confirmed by the Bankruptcy Court, or that any such plan or plans will be consummated. As provided by the Bankruptcy Code, the Debtors initially had the exclusive right to submit a plan or plans of reorganization for 120 days from the date the petitions were filed. On October 17, 2000, the Debtors received Bankruptcy Court approval to extend the exclusive period to file a plan or plans of reorganization in the Chapter 11 Cases from October 7, 2000, to April 30, 2001, and extended the Debtors' exclusive right to solicit acceptances of such plan or plans from December 6, 2000, to June 29, 2001. On May 16, 2001, the Debtors received Bankruptcy Court approval to further extend the exclusive period to file a plan or plans of reorganization in the Chapter 11 Cases to September 19, 2001, and extended the Debtors' exclusive right to solicit acceptances of such plan or plans to November 19, 2001. On February 11, 2002, the Debtors received Bankruptcy Court approval to further extend the exclusive period to file a plan or plans of reorganization in the Chapter 11 Cases to April 30, 2002 and extended the Debtors' exclusive right to solicit acceptances of the plan or plans to June 30, 2002. Currently, it is not possible to predict the length of time the Debtors will operate under the protection of Chapter 11, the outcome of the Chapter 11 proceedings in general, or the effect of the proceedings on the business of Safety-Kleen or on the interests of the various creditors and security holders. Under the Bankruptcy Code, post-petition liabilities and pre-petition liabilities subject to compromise must be satisfied before shareholders can receive any distribution. The ultimate recovery to Safety-Kleen Corp. shareholders, if any, will not be determined until the end of the case when the fair value of the Debtors' assets is compared to the liabilities and claims against the Debtors. There can be no assurance as to what value, if any, will be ascribed to the Safety-Kleen Corp. common stock in the bankruptcy proceedings. Safety-Kleen Corp. does not believe that their common shareholders will receive any distribution upon consummation of a plan or plans of reorganization. Certain of Safety-Kleen Corp.'s domestic subsidiaries which filed the Chapter 11 Cases are included in the accompanying Combined Balance Sheets. 2. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES A summary of the basis of presentation and the significant accounting policies followed in the preparation of these Combined Balance Sheets is as follows: Basis of Presentation The accompanying Combined Balance Sheets of the Company have been prepared on a going concern basis, which contemplates continuity of operations, realization of assets, and payment of liabilities in the ordinary course of business, and do not reflect adjustments that might result if the Company is unable to continue as a going concern. The Debtors' history of significant losses, stockholders' deficit and their Chapter 11 filings, as well as issues related to compliance with debt covenants and financial assurance requirements discussed in Notes 7 and 10, raise substantial doubt about the Company's ability to continue as a going concern. The Debtors intend to file a plan or plans of reorganization with the Bankruptcy Court. Continuing as a going concern is dependent upon, among other things, the Debtors' formulation of a plan or plans of reorganization, the success of future business operations, and the generation of sufficient cash from operations and financing sources to meet Debtors' obligations. The accompanying Combined Balance Sheets do not reflect: (i) the realizable value of assets on a liquidation basis or their availability to satisfy liabilities; (ii) aggregate pre-petition liability amounts that may be allowed for unrecorded claims or contingencies, or their status or priority; (iii) the effect of any changes to the Company's capital structure or in the Company's business operations as the result of an approved plan or plans of reorganization; or (iv) adjustments to the carrying value of assets (including goodwill and other intangibles) or liability amounts that may be necessary as a result of actions by the Bankruptcy Court. 5

The Company's Combined Balance Sheets at August 31, 2001 and 2000 have been presented in conformity with the AICPA's Statement of Position 90-7, "Financial Reporting By Entities in Reorganization Under the Bankruptcy Code", ("SOP 90-7"). This statement requires, among other things, a segregation of liabilities subject to compromise by the Bankruptcy Court as of the bankruptcy filing date and identification of all transactions and events that are directly associated with the reorganization of the Debtors. In recording liabilities subject to compromise, the Company must make certain estimates relating to the amounts it expects to be allowed in the bankruptcy proceeding. The actual amounts required to settle these claims could significantly differ from the amounts currently recorded. The accompanying Combined Balance Sheets of the Company at August 31, 2001, 2000 and 1999 have been presented on a carve-out basis. As further discussed below, certain assets and liabilities in the Combined Balance Sheets include allocations, primarily from Corporate. Management believes that the allocations are made on a reasonable basis; however, the Combined Balance Sheets may not necessarily reflect the financial position of the Company if the Company had been a separate, stand-alone entity during the periods presented. Accounting principles generally accepted in the United States and the regulations of the Securities and Exchange Commission ("SEC") require the inclusion of a statement of operations, cash flows and changes in stockholders' equity. As reported in Safety-Kleen's Form 10-K/A filed with the SEC, Safety-Kleen Corp. and the Company have identified material deficiencies in many of the financial systems, processes and related internal controls. As a result, the Company is unable to prepare, for audit, a combined statement of operations, combined statement of cash flows, combined statement of changes in parent company investment, net or an abbreviated statement of operations such as a statement of revenues and direct expenses. The parent company investment, net in the accompanying Combined Balance Sheets includes the net intercompany balances, including those subject to compromise (see Note 8). Combination The accompanying Combined Balance Sheets include the accounts of the Company. All significant intracompany balances have been eliminated as part of the combination. All intercompany balances are included as a component of parent company investment, net in the accompanying Combined Balance Sheets. Cash and Cash Equivalents Cash and cash equivalents consist of cash on deposit and term deposits in investments with initial maturities of three months or less. These investments are stated at cost, which approximates market value. Restricted Funds Held By Trustees Restricted funds held by trustees are included in other assets and consist principally of financial assurance funds deposited in connection with landfill final closure and post-closure obligations, amounts held for landfill and other construction arising from industrial revenue financings, and amounts held to establish a GSX Contribution Fund for the Pinewood Facility (see Note 10). These amounts are principally invested in fixed income securities of federal, state and local governmental entities and financial institutions. The Company considers its landfill closure, post-closure, construction and escrow investments totaling $2.0 million, $12.4 million and $13.0 million at August 31, 2001, 2000 and 1999, respectively, to be held to maturity. The Company has the ability, and management has the intent, to hold investment securities to maturity. Reductions in market value considered by management to be other than temporary are reported as a realized loss and reduction in the cost basis of the security. At August 31, 2001, 2000 and 1999 the aggregate fair value of these investments approximate their net book value and substantially all of these investments mature within one year. The GSX Contribution Fund for the Pinewood Facility totaling $20.2 million, $19.1 million and $18.3 million at August 31, 2001, 2000 and 1999, respectively, has been treated as if it were available for sale (see Note 10). Accordingly, unrealized gains and losses resulting from changes between the cost basis and fair value of the securities in this fund are recorded as adjustments to parent company investment, net. Inventories and Supplies Inventories consist primarily of supplies and repair parts, which are valued at the lower of cost or market as determined on a first-in, first-out basis. The Company periodically reviews its inventories for obsolete or unsaleable items and adjusts its carrying value to reflect estimated realizable values. Property, Plant and Equipment Property, plant and equipment are recorded at cost. Expenditures for major renewals and improvements, which extend the life or usefulness of the asset, are capitalized. Items of an ordinary repair or maintenance nature, as well as major maintenance activities, are charged directly to operating expense as incurred. The Company capitalizes expenditures which extend the life of the related property or mitigate or prevent future environmental contamination. During the construction and development period of an asset, the costs incurred, including applicable interest costs, are classified as construction-in-process. Once an asset has been completed and placed in service, it is transferred to the appropriate category and depreciation 6

commences. In addition, the Company capitalizes applicable interest costs associated with partially developed landfill sites, which are included in land, landfill sites and improvements (see Note 4). Depreciation and amortization of certain property, plant and equipment is provided on a straight-line basis over their estimated useful lives, with the exception of landfill assets, for which depreciation and amortization are provided on a units of production or capacity basis. Leasehold improvements are capitalized and amortized over the shorter of the improvement life or the remaining term of the lease plus renewal period. Intangible Assets The Company evaluates the excess of the purchase price over the amounts assigned to tangible assets and liabilities (excess purchase price) associated with each of its acquisitions to value the identifiable intangible assets. Any portion of the excess purchase price that cannot be separately identified represents goodwill. The Company evaluates the estimated economic lives of each asset, including goodwill, and has amortized the asset over that life. Permits -- The Company has reflected the excess of the fair value of non-landfill facilities over the tangible assets acquired as permits. The Company has determined the value of acquired permits based on either a discounted cash flow or other appraisal method. The Company has evaluated and determined that the non-landfill permits have estimated economic lives in excess of 40 years, but believes 40 years is appropriate for amortization of these assets. Accordingly, the Company is amortizing the value of permits over a period of 40 years. Goodwill -- The remaining excess purchase price of acquired companies, following the allocation to permits and the identified intangible assets discussed above, has been classified as goodwill. The Company considers legal, contractual, regulatory, obsolescence and competitive factors in determining the useful life and amortization period of this intangible asset. The Company believes the goodwill associated with the acquired companies has estimated lives ranging from 40 years to an undeterminable life. As such, the Company has amortized the goodwill over 40 years. Goodwill is reviewed for impairment when events or circumstances indicate it may not be recoverable. If it is determined that goodwill may be impaired and the estimated undiscounted future cash flows, excluding interest, of the underlying business are less than the carrying amount of the goodwill, then an impairment loss is recognized. The impairment loss is based on the difference between the fair value of the underlying business and the carrying amount. The method of determining fair value differs based on the nature of the underlying business. Impairment of Long-Lived Assets In accordance with Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of", the Company periodically evaluates whether events and circumstances have occurred that indicate that the remaining useful life of any of its tangible and intangible assets may warrant revision or that the carrying amounts might not be recoverable. When factors indicate that the tangible and intangible assets should be evaluated for possible impairment, the Company uses an estimate of the future undiscounted cash flows generated by the underlying assets to determine if a write-down is required. If a write-down is required, the Company adjusts the book value of the underlying goodwill and then the book value of the impaired long-lived assets to their estimated fair values (see Note 4). Deferred Financing Costs Deferred financing costs of $0.4 million at August 31, 1999 have been recorded for borrowings directly related to the Company. Additional deferred financing costs have been allocated to the Company to the extent and in the same manner as the underlying allocated debt instruments. See allocation methodology summary and debt instrument allocation below. Deferred financing costs are amortized over the life of the related debt instrument and are included in other assets in the accompanying Combined Balance Sheets at August 31, 2001, 2000 and 1999. As a result of the Chapter 11 Cases discussed in Note 1, deferred financing costs at the date of the filing of $14.8 million related to pre-petition debt instruments were written off. Landfill Accounting and Environmental Liabilities Environmental liabilities include accruals for the estimates of the Company's obligations associated with: .. Regulatory mandated landfill cell closure, final closure and post-closure activities. The Company accrues cell closure costs over the life of the cell, and accrues final closure and post-closure costs over the life of the landfill, as capacity is consumed. .. Regulatory mandated closure and post-closure activities for facilities other than landfills, such as incinerators. The Company accrues these costs when management commits to a definitive plan of closure with respect to the facility. .. Costs associated with remedial environmental matters at the Company's facilities. The Company accrues for these costs on a site-by-site basis, when management deems such obligations to be probable and reasonably estimable. 7

.. Sites named on the United States Environmental Protection Agency's National Priorities List ("Superfund") with which the Company is allegedly connected. The Company typically accrues its estimate of its obligations related to these sites no later than the completion of a remedial investigation and/or feasibility study. Accruals are adjusted if, and as, further information relative to the underlying obligations develop or circumstances change. Changes in estimated landfill cell closure, final closure and post-closure liabilities are recognized prospectively. Changes in the Company's estimates of its obligations relative to non-landfill closure and post-closure activities, remedial situations and Superfund sites are recorded in the period in which the estimates change. In conjunction with the acquisitions of certain facilities, the Company has obtained varying amounts and types of indemnification from potential environmental liabilities existing at the time of acquisition. Such indemnities typically cover all or a portion of the costs associated with the remediation of such pre-existing environmental liabilities, and may be for a limited period of time. No liabilities are recorded at the acquisition date if it is probable that the indemnifying party has the intent and financial ability to perform under those indemnities. Indemnifications contractually required of Laidlaw have not been considered in the determination of the Company's environmental liabilities (see Note 14). Site costs -- Site costs include the costs of landfill site acquisition, permitting, preparation and improvement. These amounts are recorded at cost, which includes capitalized interest, as applicable. Site costs, net of amortization, are combined with management's estimate of the costs required to complete construction of the landfill to determine the amount to be amortized over the remaining estimated useful economic life of a site. Amortization of site costs is recorded on a units-of-consumption basis, such that the site costs should be completely amortized at the date the landfill ceases accepting waste. Final closure and post-closure obligations for landfills -- Final closure costs include the costs required to cap the final cell of the landfill and the costs required to dismantle certain structures for landfills and other landfill improvements. In addition, final closure costs include regulatory mandated groundwater monitoring, leachate management, financial assurance and other costs incurred in the closure process. Post-closure costs include substantially all costs that are required to be incurred subsequent to the closure of the landfill, including, among others, groundwater monitoring, leachate management, and financial assurance. Regulatory post-closure periods are generally 30 years after landfill closure, but may be as long as 100 years after landfill closure. Final closure and post-closure obligations are discounted. Final closure and post-closure obligations are accrued on a units-of-consumption basis, such that the present value of the final closure and post-closure obligations is accrued at the date the landfill discontinues accepting waste. Landfill capacity -- Landfill capacity, which is the basis for the amortization of site costs and for the accrual of final closure and post-closure obligations, represents total permitted airspace, plus unpermitted airspace that management believes is probable of ultimately being permitted based on established criteria. The Company applies a comprehensive set of criteria for evaluating the probability of obtaining a permit for future expansion airspace at existing sites, which provides management a sufficient basis to evaluate the likelihood of success of unpermitted expansions. Those criteria are as follows: .. Personnel are actively working to obtain the permit or permit modifications (land use, state and federal) necessary for expansion of an existing landfill, and progress is being made on the project; .. At the time the expansion is included in the Company's estimate of the landfill's useful economic life, it is probable that the required approvals will be received within the normal application and processing time periods for approvals in the jurisdiction in which the landfill is located. The Company expects to submit the application within the next year and expects to receive all necessary approvals to accept waste within the next five years; .. The owner of the landfill or the Company has a legal right to use or obtain land associated with the expansion plan; .. There are no significant known political, technical, legal, or business restrictions or issues that could impair the success of such expansion; .. A financial feasibility analysis has been completed, and the results demonstrate that the expansion has a positive financial and operational impact such that management is committed to pursuing the expansion; and .. Additional airspace and related additional costs, including permitting, final closure and post-closure costs, have been estimated based on the conceptual design of the proposed expansion. Exceptions to the criteria set forth above may be approved through a landfill-specific approval process that includes prompt approval from Safety-Kleen's Chief Financial Officer and review by the Audit Committee of the Board of Directors of Safety-Kleen. At August 31, 2001, 2000 and 1999, there were two unpermitted expansions included in the Company's landfill accounting model, which together represented approximately 1% of the Company's remaining airspace at these dates. Neither of these expansions represented exceptions to the Company's established criteria. 8

At August 31, 2001, the Company has 10 active landfill sites (including the Company's non-commercial landfill), which have estimated remaining lives (based on anticipated waste volumes) and property, plant and equipment, net as follows ($ in thousands): Remaining Number of Property, plant lives (years) sites and equipment, net ------------- --------- ------------------ 0-5 3 $ 18,910 6-10 -- -- 11-20 4 40,803 21-40 -- -- 40 + 3 16,862 --------- ------------------ 10 $ 76,575 --------- ------------------ Amortization of cell construction costs and accrual of cell closure obligations - -- Landfills are typically comprised of a number of cells, which are constructed within a defined acreage (or footprint). The cells are typically discrete units, which require both separate construction and separate capping and closure procedures. Cell construction costs are the costs required to excavate and construct the landfill cell. These costs are typically amortized on a units-of-consumption basis, such that they are completely amortized when that specific cell ceases accepting waste. Cell closure costs, which are the costs required to construct the cell cap, are accrued over the life of the cell. These costs are typically accrued on a units-of-consumption basis, such that the total amount required to cap the cell is accrued when the specific cell ceases accepting waste. In some instances, the Company has landfills that are engineered and constructed as "progressive trenches." In progressive trench landfills, a number of contiguous cells form a progressive trench. In those instances, the Company amortizes cell construction costs, and accrues cell closure obligations, over the airspace within the entire trench, such that the cell construction costs will be fully amortized, and the cell closure costs will be fully accrued, when that specific progressive trench ceases accepting waste. Final closure and post-closure obligations for facilities other than landfills - -- Final closure costs include costs required to dismantle and decontaminate certain structures, financial assurance and other costs incurred during the closure process. Post-closure costs, if required, include associated maintenance and monitoring costs and financial assurance costs as required by the closure permit. Post-closure periods are performance based and are not generally specified in terms of years in the closure permit, but may generally range from 10 to 30 years or more. These obligations generally are not discounted. Remedial liabilities, including Superfund liabilities -- Remedial liabilities include the costs of removal or containment of contaminated material, the treatment of potentially contaminated groundwater and maintenance and monitoring costs necessary to comply with regulatory requirements. Discounting of long-term environmental related liabilities -- Costs of future expenditures for landfill final closure and post-closure are discounted based on management's expectations of when it will incur the expenditure. Generally, remediation obligations are not discounted. However, in limited instances, certain remediation obligations are discounted if they are closely connected to the regulatory post-closure obligations and/or the amount and timing of the cash payments are fixed and reliably determinable. Credit Concentration Concentration of credit risks in accounts receivable is limited due to the large number of customers comprising the Company's customer base throughout North America. The Company performs periodic credit evaluations of its customers. The Company establishes an allowance for uncollectible accounts based on the credit risk applicable to particular customers, historical trends and other relevant information. Revenue Recognition The Company recognizes revenue in accordance with SEC Staff Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Consolidated Financial Statements." SAB No. 101 requires that four basic criteria must be met before revenue can be recognized: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the fee is fixed and determinable; and (iv) collectibility is reasonably assured. In accordance with SAB No. 101, the Company recognizes revenue upon disposal for its waste collection and disposal activities. Unearned revenue has been recorded for services billed but not earned in the accompanying Combined Balance Sheets. Direct costs associated with the handling and transportation of waste prior to disposal are capitalized as a component of other current assets in the accompanying Combined Balance Sheets. Deferral periods related to unearned revenue and the related direct costs typically range from one to six months. Income Taxes The Company's domestic operating results are included in Safety-Kleen's consolidated income tax returns. Certain of the Company's Canadian operations file separately for tax purposes. Income taxes have been presented in the accompanying Combined Balance Sheets as if the Company's domestic operations filed its returns on a consolidated basis. Current tax liabilities are presented as if such obligations are due 9

to taxing authorities. Deferred income taxes reflect the tax consequences on future years of differences between the tax bases of assets and liabilities and their financial reporting amounts. Future tax benefits, such as net operating loss carryforwards, are recognized to the extent that realization of such benefits is more likely than not. Foreign Currency Foreign operations' balances are translated according to the provisions of SFAS No. 52, "Foreign Currency Translation". The functional currency of each foreign operation is in its respective local currency. Assets and liabilities are translated to U.S. Dollars at the exchange rate in effect at the balance sheet date. Cumulative translation adjustments are included in parent company investment, net in the accompanying Combined Balance Sheets. Recorded balances that are denominated in a currency other than the functional currency are adjusted to the functional currency using the exchange rate at the balance sheet date. Allocation Methodology The accompanying Combined Balance Sheets of the Company at August 31, 2001, 2000 and 1999, have been presented on a carve-out basis. For all periods presented, certain assets and liabilities in the Combined Balance Sheets include allocations, primarily from Corporate. To the extent that an asset or liability is identifiable and directly related to the Company, it is reflected in the accompanying Combined Balance Sheets. For assets and liabilities that are indirectly related to the Company, management has developed reasonable methods to allocate these assets and liabilities. Assets or liabilities that exclusively relate to corporate level activities are not allocated to the Company. All of the allocations and estimates in the Combined Balance Sheets are based on assumptions that management believes are reasonable under the circumstances. However, the financial information included herein may not reflect the financial position of the Company in the future or what it would have been had the Company been a separate, stand-alone entity during the years presented. The following specific allocation methodologies of selected assets or liabilities were used by management to prepare the accompanying Combined Balance Sheets: Other current assets - Safety-Kleen has certain insurance policies which provide coverage for all its divisions and for which any related prepaid asset has historically been included in other current assets of Corporate. As these policies provide coverage to all divisions, the prepaid assets applicable to the Company were allocated using the following methods: .. Prepaid automobile insurance - At August 31, 2000, the allocation was based on the number of vehicles per division, resulting in $0.3 million of prepaid automobile insurance allocation to the Company. No allocations were required at August 31, 2001 or 1999. .. Prepaid worker's compensation and general liability insurance - At August 31, 2000, the allocation was based on claims history, resulting in $0.2 million of prepaid worker's compensation and general liability insurance allocation to the Company. No allocations were required at August 31, 2001 or 1999. .. Prepaid environmental impairment liability ("EIL") insurance - Allocations were based on covered items obtained from facility listings, non-owned facility listings and transporter listings. Based on this methodology, $0.1 million, $0.2 million and $0.3 million of prepaid EIL insurance was allocated to the Company at August 31, 2001, 2000 and 1999, respectively. .. Prepaid financial assurance - Allocations for all years presented considered the amount of financial assurance coverage required at individual Company facilities in relation to the total premiums for those specific Company facilities, based on the August 31, 2001 policies. Based on this methodology, $1.1 million, $1.6 million, and $1.4 million of prepaid financial assurance insurance was allocated to the Company at August 31, 2001, 2000 and 1999, respectively. Property, plant and equipment, net - Computer equipment, office equipment and other equipment recorded on Corporate were allocated based on headcount. Leasehold improvements were allocated based on the facility to which they relate. Based on this methodology, $4.3 million, $3.7 million and $0.8 million of equipment and leasehold improvements, net, were allocated to the Company at August 31, 2001, 2000 and 1999, respectively. Other assets - Deferred financing costs of $0.4 million, $1.4 million and $16.8 million were allocated to the Company in a manner consistent with the associated debt instruments at August 31, 2001, 2000 and 1999, respectively. See discussion of long-term debt and other financing allocations below. Accounts payable - Accounts payable recorded on Corporate that could not specifically be identified as relating to the Company, BSSD or Corporate were allocated on the basis of total Corporate costs charged to the Company during the fiscal year, resulting in $0.6 million, $0.9 million and $2.6 million of allocations to the Company at August 31, 2001, 2000 and 1999, respectively. 10

Accrued other liabilities - The significant allocations related to accrued other liabilities are as follows: .. At August 31, 2001, 2000 and 1999, $3.4 million, $1.0 million and $8.0 million, respectively, of accrued interest payable was allocated to the Company in a manner consistent with the associated debt instruments. See discussion of long-term debt and other financing allocations below. .. Accrued professional fees related to attorneys and consultants used by Safety-Kleen specifically for environmental issues were allocated based on financial assurance coverage requirements. Professional fees related to the bankruptcy, restructuring, the restatement and other external reporting requirements of Safety-Kleen are considered costs of corporate activities and have not been allocated to the Company. Based on this methodology, $2.0 million and $0.1 million of accrued professional fees were allocated to the Company at August 31, 2001 and 1999, respectively. No allocations were required at August 31, 2000. .. Accruals for fully self-insured employee-related health care benefits were allocated based on relevant headcount. At August 31, 2001, 2000 and 1999, $1.9 million, $1.9 million and $1.4 million, respectively, of health care accruals were allocated to the Company. .. Safety-Kleen estimates accruals for self-insured worker's compensation, general liability (including product liability), property, and vehicle liability, based on actuarially determined estimates of the incurred but not reported claims plus any reported but not paid claims and premiums. Accruals for premiums not paid at August 31, 2001, 2000 and 1999, were allocated based on revenue by division. Accruals for incurred but not reported claims and reported but not paid claims were allocated based upon actuarial claims data. At August 31, 2001, 2000 and 1999, $2.2 million, $0.2 million and $1.7 million, respectively, of related insurance accruals were allocated to the Company. .. Accruals for penalties assessed by the United States Environmental Protection Agency ("EPA") and various states for alleged violations of federal and state financial assurance requirements under the Toxic Substance Control Act ("TSCA"), and the Resource Conservation and Recovery Act ("RCRA") and state hazardous waste programs are also included in accrued other liabilities at August 31, 2001 and 2000. Approximately $3.1 million and $0.6 million of these accruals were allocated to the Company at August 31, 2001 and 2000, respectively, based on financial assurance coverage requirements by facility. No allocations were required at August 31, 1999. Income taxes - All income tax related assets and liabilities are computed based on the separate return method. Current tax liabilities are presented as if such obligations are due to taxing authorities. See Note 13 for further discussion. Derivative instruments - During fiscal 2000 and 1999, Safety-Kleen participated in significant derivative transactions both to hedge its interest rate exposure and for trading purposes. Qualifying hedges, which were not required to be reported on the balance sheet under accounting principles generally accepted in the United States in effect at these dates, do not impact the accompanying Combined Balance Sheets. Derivative trading transactions are considered corporate activities that are not allocated to the Company. Other long-term liabilities - The long-term portion of self-insured worker's compensation and general liability (including product liability) accruals are included in other long-term liabilities and were allocated as discussed above. At August 31, 2001, 2000 and 1999, $2.8 million, $1.1 million and $1.1 million, respectively, of long-term self-insured worker's compensation and general liability insurance accruals were allocated to the Company. Long-term debt and other financing - All debt instruments directly related to the operations of the Company are included in the accompanying Combined Balance Sheets. Debt instruments not specifically attributable to the operations of the Company or BSSD have been allocated to the respective operating divisions considering the purchase price of Old Safety-Kleen and the market capitalization of LESI at the time of that acquisition and the associated refinancing. See Note 7 for further discussion. Liabilities subject to compromise - As discussed in Note 8, certain liabilities have been classified as subject to compromise under bankruptcy reorganization proceedings. The liabilities subject to compromise recorded at Corporate which required allocations at August 31, 2001 and 2000, consist of certain trade accounts payable, accrued insurance liabilities, accrued interest and long-term debt. These liabilities were allocated as described above. Other liabilities subject to compromise that are reflected in the accompanying Combined Balance Sheets relate specifically to the Company. Use of Estimates The preparation of the Combined Balance Sheets in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Combined Balance Sheets. Certain estimates require management's judgement, and when applied, materially affect the Company's Combined Balance Sheets. The Company considers the "Basis of Presentation" (see above), environmental liabilities, income taxes, asset impairments, litigation contingencies, Safety-Kleen (Pinewood), Inc. and recent accounting developments to include estimates and assumptions that required or will require management's judgement. These estimates involve matters that are inherently uncertain in nature and have a material effect on the accompanying Combined Balance Sheets. Actual results could differ materially from those estimates. 11

Recent Accounting Developments In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities", which establishes accounting and reporting standards requiring that every derivative instrument (including certain derivative instruments embedded in other contracts) be recorded in the balance sheet as either an asset or liability measured at its fair value. The Statement requires that changes in a derivative's fair value be recognized currently in earnings unless specific hedge accounting criteria are met. Special accounting for qualifying hedges allows a derivative's gains and losses to offset related results on the hedged item in the income statement, and requires that a company must formally document, designate and assess the effectiveness of transactions that receive hedge accounting. In June 1999, the FASB issued SFAS No. 137, "Accounting for Derivative Instruments and Hedging Activities - Deferral of the Effective Date of FASB Statement No. 133", which delayed the original effective date of SFAS No. 133 until fiscal years beginning after June 15, 2000. In June 2000, the FASB issued SFAS No. 138, "Accounting for Certain Derivative Instruments and Certain Hedging Activities", which amends SFAS No. 133. SFAS No. 138 addresses a limited number of issues related to the implementation of SFAS No. 133. On September 1, 2001, the Company adopted the provisions of SFAS No. 133, as amended. The Company is not a party to any significant derivative contracts. Therefore, the adoption of SFAS 133 had no impact on the Company's financial position. In July 2001, the FASB issued SFAS No. 141, "Business Combinations", and SFAS No. 142, "Goodwill and Other Intangible Assets." SFAS No. 141 requires that the purchase method of accounting be used for all business combinations initiated or completed after June 30, 2001. SFAS No. 141 also specifies criteria for intangible assets acquired in a business combination to be recognized and reported apart from goodwill. SFAS No. 142 requires that goodwill and intangible assets with indefinite useful lives no longer be amortized, but instead be tested for impairment at least annually in accordance with the provisions of SFAS No. 142. SFAS No. 142 also requires that intangible assets with definite useful lives be amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment in accordance with SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." The Company is required to adopt the provisions of SFAS No. 141 immediately for new transactions and SFAS No. 142 at the earlier of its emergence from bankruptcy or September 1, 2002. Early adoption of SFAS No. 142 is permitted. The Company's existing goodwill and intangible assets will continue to be amortized prior to the adoption of SFAS No. 142. Upon adoption of SFAS No. 142, the Company must evaluate its existing intangible assets and goodwill. Upon adoption of SFAS No. 142, the Company will be required to reassess the useful lives and residual values of all recorded intangible assets, and make any necessary amortization period adjustments by the end of the second fiscal quarter following adoption. Additionally, to the extent an intangible asset is identified as having an indefinite useful life, the Company will be required to test the intangible asset for impairment in accordance with the provisions of SFAS No. 142 by the end of the second fiscal quarter following adoption. Any impairment loss will be measured as of the date of adoption and recognized as the cumulative effect of a change in accounting principle. As of September 1, 2002, the Company expects to have unamortized goodwill of approximately $96 million, which will be subject to the transition provisions of SFAS No. 142. The Company believes it will likely incur a write-down in the value of its intangible assets at the earlier of its emergence from bankruptcy, as provided by SOP 90-7, or the adoption of SFAS No. 142. In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations." SFAS No. 143 will require, upon adoption, that the Company recognize as a component of asset cost, the fair value of a liability for an asset retirement obligation in the period in which it is incurred if a reasonable estimate of fair value can be made. Under this statement, the liability is discounted and accretion expense is recognized using the credit-adjusted risk-free interest rate in effect when the liability was initially recognized. SFAS No. 143 is effective for financial statements issued for fiscal years beginning after June 15, 2002. The Company will be required to adopt SFAS No. 143 at the earlier of its emergence from bankruptcy or September 1, 2002. The Company is currently in the process of evaluating the impact of SFAS No. 143; however, the adoption of this standard is expected to result in the recognition of additional assets and liabilities. In August 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." This statement supersedes FASB statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" and the accounting and reporting provisions of APB Opinion No. 30, "Reporting the Results of Operations - Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions" for the disposal of a segment of a business (as previously defined in that opinion). SFAS No. 144 is effective for financial statements issued for fiscal years beginning after December 15, 2001. The Company will be required to adopt SFAS No. 144 at the earlier of its emergence from bankruptcy or September 1, 2002. The new rules change the criteria for classifying an asset as held-for-sale. The standard also broadens the scope of businesses to be disposed of that qualify for reporting as discontinued operations, and changes the timing of recognizing losses on such operations. The Company is currently in the process of evaluating the potential impact that the adoption of SFAS No. 144 will have on its combined financial position. 12

LONG-LIVED ASSETS Property, Plant and Equipment Net property, plant and equipment at August 31, 2001, 2000, and 1999 consist of the following ($ in thousands): Range of Estimated 2001 2000 1999 Useful Lives --------- --------- --------- ------------------ Land $ 22,586 $ 25,260 $ 42,500 N/A Landfill sites and improvements 173,278 170,746 428,423 0-126 years Buildings 80,349 81,152 150,560 20-40 years Machinery and equipment 165,730 176,266 263,160 3-40 years Lesser of useful life Leasehold improvements 1,600 1,692 2,355 or lease term Construction in process 6,669 6,611 10,098 N/A --------- --------- --------- Total property, plant and equipment 450,212 461,727 897,096 Less: Accumulated depreciation and amortization (210,052) (199,546) (331,312) --------- --------- --------- Property, plant and equipment, net $ 240,160 $ 262,181 $ 565,784 ========= ========= ========= During fiscal 2001, the Company had no capitalized interest costs, as contractually required interest payments have been stayed by the Chapter 11 Cases. During fiscal 2000 and 1999, the Company capitalized total interest costs of $1.2 million and $2.4 million, respectively. Intangible Assets Net intangible assets at August 31, 2001, 2000 and 1999 consist of the following ($ in thousands): 2001 2000 1999 --------- --------- --------- Permits, non-landfill $ 308,648 $ 308,774 $ 324,809 Goodwill 109,585 112,029 192,742 --------- --------- --------- Total intangible assets 418,233 420,803 517,551 Less: accumulated amortization (84,875) (73,611) (70,495) --------- --------- --------- Intangible assets, net $ 333,358 $ 347,192 $ 447,056 ========= ========= ========= Impairment and Other Charges SFAS No. 121 requires the assessment of long-lived assets for impairment whenever events ("Triggering Events") occur which may indicate that those assets have become impaired. Triggering Events may be events, which directly cause impairment (e.g., decisions to close facilities or the effects of new government regulations) or may be indicators of the existence of other direct causes of impairment (e.g., continuing or increasing losses, declining customer demand, etc.). The Company believes that the Chapter 11 Cases and the events that led up to it constitute triggering events. In connection with its comprehensive review of its operations, the Company evaluated the recoverability of long-lived assets at August 31, 2001 and 2000 by reference to estimated future cash flows. As a result, the Company identified certain impairments that have been recorded in fiscal 2001, 2000 and 1999 (see table below). 13

Fair values for impaired assets were determined for landfills, incinerators, wastewater treatment and other facilities, primarily based on future cash flow projections discounted using rates appropriate for the risks involved with the identified assets. For those facilities that were to be sold, management based fair value on their best estimate of sales value less cost to sell. Fiscal 2001 The components of fiscal 2001 impairments consisted of the following ($ in thousands): Provision for early facility closures and post-closures: Bridgeport incinerator $ 34,123 Coffeyville incinerator 9,017 Hilliard wastewater treatment facility 1,174 Burton transportation facility 459 --------- Total 44,773 Asset impairment and other charges 5,395 --------- Total $ 50,168 ========= During fiscal 2001, the Company ceased operations at two incinerators, a wastewater treatment facility and a transportation facility. As a result of these closures, the Company recorded a provision for early facility closures and post-closures of approximately $44.8 million. Certain post-closure costs are expected to be incurred over a period approximating 30 years. The Company also recorded approximately $5.4 million of impairment charges primarily related to a wastewater treatment facility. Fiscal 2000 The components of fiscal 2000 impairments consisted of the following ($ in thousands): Service centers and landfills related to western operations $ 118,336 Other landfills and incinerators 118,622 Harbor facility -- closed 17,691 Pinewood facility 15,724 Other facilities 73,823 --------- Total $ 344,196 ========= The amounts shown as related to western operations relate to facilities which are located in the western region of the United States. Their markets have been adversely affected by competitive conditions, including over supply of available services, which have limited the Company's ability to increase prices to recover increased costs, including those related to new environmental regulations. Included in other landfills and incinerators is an incinerator constructed to burn contaminated soils. Although significant revenue resulted from unusual events in fiscal 1999 and 2000, the general level of demand for these services has and is expected to continue to decline. In addition, new environmental regulations are projected to significantly increase capital expenditures and operating costs in the future. Also included in this amount is a landfill which has been the primary disposal site for the soil burned at this Company owned incinerator. The projected declines in volumes generated at the incinerator are projected to have a continuing adverse effect on volumes at the landfill. As discussed in Note 10, the Pinewood Facility has been the subject of lengthy, complex and protracted legal proceedings. The results of the proceedings have been adverse to the Company; accordingly, the Company has concluded that it would be imprudent to assume that this facility will generate any significant future revenue. An additional charge was recorded for the impairment of the remaining net book value of fixed assets at the Pinewood Facility. Appropriate reserves for closure and post-closure costs at the Pinewood Facility have been fully provided. Fiscal 1999 The components of fiscal 1999 impairments consisted of the following ($ in thousands): Write-down of permits $ 9,195 Property, plant & equipment 2,092 --------- Total $ 11,287 ========= Impairments in 1999 were primarily due to factors relating to decisions made by management as a result of changes in business conditions or legal issues. These amounts represent the write-down of property, plant and equipment and intangibles. 14

5. ACCRUED OTHER LIABILITIES Accrued other liabilities at August 31, 2001, 2000 and 1999 consist of the following ($ in thousands): 2001 2000 1999 ----------- ----------- ------------ Accrued interest payable $ 3,365 $ 969 $ 9,926 Accrued employee salaries and benefits 14,261 8,033 7,670 Accrued professional fees 2,028 609 1,365 Accrued insurance 4,102 2,143 3,158 Accrued taxes 5,039 3,471 6,347 Accrued other 3,780 3,071 5,118 ----------- ----------- ------------ $ 32,575 $ 18,296 $ 33,584 ----------- ----------- ------------ 6. CLOSURE, POST-CLOSURE AND ENVIRONMENTAL REMEDIATION LIABILITIES The Company records environmentally related accruals for both its landfill and non-landfill operations. See Note 2 for further discussion of the Company's methodology for estimating and recording these accruals. Final closure and post-closure liabilities -- The Company has material financial commitments for the costs associated with requirements of the EPA, and the comparable regulatory agency in Canada for the final closure and post-closure activities at the majority of its facilities. In the United States, the final closure and post-closure requirements are established under the standards of the EPA, and are implemented and applied on a state-by-state basis. Estimates for the cost of these activities are developed by the Company's engineers, accountants and external consultants, based on an evaluation of site-specific facts and circumstances, including the Company's interpretation of current regulatory requirements and proposed regulatory changes. Such estimates may change in the future due to various circumstances including, but not limited to, permit modifications, changes in legislation or regulations, technological changes and results of environmental studies. Final closure and post-closure plans are established in accordance with the individual site permit requirements. Landfill post-closure periods are generally expected to be for a period of 30 years after closure, but may extend to a period of 100 years. See Note 10 for a discussion of the Pinewood Facility. For purchased landfills, the Company assesses and records the present value of the estimated closure and post-closure liability based upon the estimated final closure and post-closure costs and the percentage of airspace consumed as of the purchase date. Thereafter, the difference between the liability recorded at the time of acquisition and the present value of total estimated final closure and post-closure costs to be incurred is accrued prospectively on a units of consumption basis over the estimated useful economic life of the landfill. Remedial liabilities, including Superfund liabilities -- The Company periodically evaluates potential remedial liabilities at sites that it owns or operates and at sites to which it has transported or disposed of waste, including 28 Superfund sites as of March 31, 2002. The majority of the issues at Superfund sites relate to allegations that the Company, or its predecessors, transported waste to the facilities in question, often prior to the acquisition of the alleged potentially responsible party ("PRP") by the Company. The Company periodically reviews and evaluates sites requiring remediation, including Superfund sites, giving consideration to the nature (i.e., owner, operator, transporter or generator) and the extent (i.e., amount and nature of waste hauled to the location, number of years of site operations or other relevant factors) of the Company's alleged connection with the site, the regulatory context surrounding the site, the accuracy and strength of evidence connecting the Company to the location, the number, connection and financial ability of other named and unnamed PRPs and the nature and estimated cost of the likely remedy. Where the Company concludes that it is probable that a liability has been incurred, provision is made in the Combined Balance Sheets, based upon management's judgment and prior experience, for the Company's best estimate of the liability. Such estimates, which are inherently subject to change, are subsequently revised if and when additional information becomes available. The Company believes that its extensive experience in the environmental services business, as well as its involvement with a large number of sites, provides a reasonable basis for estimating its aggregate liability. It is reasonably possible that technological, regulatory or enforcement developments, the results of environmental studies or other factors could necessitate the recording of additional liabilities and/or the revision of currently recorded liabilities that could be material. The impact of such future events cannot be estimated at the current time. Discounted environmental liabilities -- When the Company believes that both the amount of a particular environmental liability and the timing of the payments are fixed or reliably determinable, its cost in current dollars is inflated using estimates of future inflation rates (2.9% at each of August 31, 2001 and 2000, and 3.6% at August 31, 1999) until the expected time of payment, then discounted to its present value using a risk-free discount rate (5.8% at each of August 31, 2001 and 2000, and 8.5% at August 31, 1999). The portion of the Company's recorded environmental liabilities (including closure, post-closure and remedial obligations) that is not inflated or discounted was approximately $203.4 million, $163.5 million and $150.8 million at August 31, 2001, 2000 and 1999, respectively. Had the Company not discounted any portion of its liability, the amount recorded would have been increased by approximately $122.9 million, $132.1 million and $145.0 million at August 31, 2001, 2000 and 1999, respectively. The Company estimates it will provide $213.9 million in additional environmental reserves (including the inflation and discount factors referred to above) over the remaining site lives of its facilities based on current estimated costs. 15

The Company has recorded liabilities for closure, post-closure and remediation obligations at August 31, 2001, 2000 and 1999 as follows ($ in thousands): 2001 2000 1999 ---------- ---------- --------- Current portion of environmental liabilities $ 32,114 $ 27,385 $ 28,568 Non-current portion of environmental liabilities 276,841 232,317 190,512 Balances included in liabilities subject to compromise (see Note 8) 10,099 8,562 -- -------- --------- --------- Total $ 319,054 $ 268,264 $ 219,080 ========= ========= ========= In the following table, reserves for environmental matters are classified at each balance sheet date based on their classification at August 31, 2001. Reserves for closure, post-closure and remediation at August 31, 2001, 2000 and 1999, respectively, consist of the following ($ in thousands): 2001 2000 1999 ---------- ---------- ---------- Landfill facilities: Cell closure $ 24,926 $ 25,174 $ 26,863 Final closure 22,222 17,732 12,635 Post-closure 67,356 61,799 30,494 Remediation 23,490 21,562 15,863 --------- --------- --------- 137,994 126,267 85,855 --------- --------- --------- Non-landfill facilities: Remediation, closure and post-closure for closed sites 156,203 115,979 114,519 Remediation (including Superfund) for open sites 24,857 26,018 18,706 --------- --------- --------- 181,060 141,997 133,225 --------- --------- --------- Total $ 319,054 $ 268,264 $ 219,080 ========= ========= ========= All of the landfill facilities included in the table above are active at August 31, 2001, except the Pinewood Facility. Total closure and post-closure reserves related to the Pinewood Facility were $51.0 million, $47.2 million and $11.8 million at August 31, 2001, 2000 and 1999, respectively. Total environmental remediation reserves related to the Pinewood Facility were $2.9 million and $0.4 million at August 31, 2001 and 2000, respectively. There were no environmental remediation reserves related to the Pinewood Facility at August 31, 1999. The South Carolina Department of Health and Environmental Control has required that an Environmental Impairment Fund ("EIF") be established for any potential environmental cleanup and restoration of environmental impairment at the Pinewood Facility. The obligation to contribute to the EIF has been treated as a commitment to restrict assets and no liability related to the obligation has been recorded at August 31, 2001, 2000 or 1999 (see Notes 2 and 10). Anticipated payments (based on current estimated costs) and anticipated timing of necessary regulatory approvals to commence work on closure, post-closure and remediation activities for each of the next five years and thereafter are as follows ($ in thousands): Year ending August 31, 2002 $ 32,114 2003 41,972 2004 37,437 2005 17,535 2006 16,001 Thereafter 387,866 --------- Subtotal 532,925 Less: Reserves to be provided (including discount of $122.9 million) over remaining site lives (213,871) --------- Total $ 319,054 ========= 16

7. LONG-TERM DEBT AND OTHER FINANCING Long-term debt and other financing presented in the accompanying Combined Balance Sheets includes debt instruments of Safety-Kleen that were specifically related to the operations of the Company, as well as an allocation of debt instruments not specifically attributable to the operations of the Company or BSSD. Those debt instruments not specifically identifiable to the Company or BSSD have been allocated to the respective operating divisions considering the purchase price of Old Safety-Kleen and the market capitalization of LESI at the time of that acquisition and the associated refinancing. Management believes that the basis for allocating long-term debt and other financing to the Company is reasonable based on the capital structure of Safety-Kleen. Long-term debt and other financing of both Safety-Kleen and the amounts allocated to the Company at August 31, 2001 consist of the following ($ in thousands): 2001 -------------------------- Safety-Kleen Company ------------ --------- First DIP Facility $ -- $ -- ----------- --------- Other Domestic Borrowings: Senior Credit Facility: Term Loans 1,137,750 398,213 Revolver 340,000 119,000 Senior Subordinated Notes, due June 1, 2008 325,000 113,750 Senior Notes, due May 15, 2009 225,000 78,750 Promissory note, due May 15, 2003 60,000 60,000 Industrial revenue bonds, due 2003-2027 80,603 80,603 Other 3,237 1,129 ----------- --------- 2,171,590 851,445 ----------- --------- Canadian Borrowings: Senior Credit Facility 45,910 16,068 Operating Facility 16,313 5,710 ----------- --------- 62,223 21,778 ----------- --------- Total debt 2,233,813 873,223 Less: Current portion not subject to compromise (62,223) (21,778) Less: Liabilities subject to compromise (see Note 8) (2,171,590) (851,445) ----------- --------- Long-term debt and other financing $ -- $ -- =========== ========= Long-term debt and other financing of both Safety-Kleen and the amounts allocated to the Company at August 31, 2000 consist of the following ($ in thousands): 2000 -------------------------- Safety-Kleen Company ------------ --------- First DIP Facility $ -- $ -- ----------- --------- Other Domestic Borrowings: Senior Credit Facility: Term Loans 1,137,750 398,213 Revolver 340,000 119,000 Senior Subordinated Notes, due June 1, 2008 325,000 113,750 Senior Notes, due May 15, 2009 225,000 78,750 Promissory note, due May 15, 2003 60,000 60,000 Industrial revenue bonds, due 2003-2027 90,900 90,900 Other 11,425 1,166 ----------- --------- 2,190,075 861,779 ----------- --------- Canadian Borrowings: Senior Credit Facility 48,269 16,894 Operating Facility 17,152 6,003 ----------- --------- 65,421 22,897 ----------- --------- Total debt 2,255,496 884,676 Less: Current portion not subject to compromise (65,421) (22,897) Less: Liabilities subject to compromise (see Note 8) (2,190,075) (861,779) ----------- --------- Long-term debt and other financing $ -- $ -- =========== ========= 17

The actual amount available under the First DIP Facility was subject to a borrowing base computation. The First DIP Facility was amended on eleven occasions which, among other things, extended the maturity date, increased the aggregate limit for letters of credit to $95 million, increased the sublimits for letters of credit for certain uses and waived the Debtors' non-compliance with certain affirmative covenants under the First DIP Facility. The Debtors were jointly and severally liable under the First DIP Facility. As of August 31, 2001, no amounts have been drawn by Safety-Kleen on the First DIP Facility and approximately $48 million of letters of credit have been issued. On March 20, 2002, the Bankruptcy Court approved Safety-Kleen's $200 million Second Amended and Restated Debtor-in-Possession Credit Facility (the "Second DIP Facility"). The Second DIP Facility extends the maturity date of the First DIP Facility until the earlier of March 22, 2003, or the effective date of a plan or plans of reorganization. In addition, it reduces the aggregate amount of borrowings available from $100 million to $75 million, which continues to be subject to borrowing base limitations ("Tranche A"). The Second DIP Facility also creates a new tranche under the credit facility in the amount of $125 million ("Tranche B"). Tranche B is available for cash borrowings and letters of credit, and has the same maturity date as Tranche A. Proceeds from Tranche A or Tranche B may be used for general corporate purposes. Tranche A is available for letters of credit or cash borrowings, with a sub-limit of $45 million available for environmental letters of credit. The letter of credit sub-limit under Tranche B is $50 million, and there is a further sub-limit of $40 million available for environmental letters of credit, including the replacement of certain existing cash collateral pledged to support financial assurance with respect to certain facilities. Tranche A letters of credit are priced at 3% per annum (plus a fronting fee of 0.25% to the Agent) on the outstanding face amount of each letter of credit. In addition, the Debtors pay a commitment fee of 0.50% per annum on the unused amount of Tranche A, payable monthly in arrears. Tranche B letters of credit are priced at 12% per annum (plus a fronting fee of 0.25% to the Agent) on the outstanding face amount of each letter of credit, payable monthly in arrears. In addition, the Debtors pay a commitment fee of 2.5% on the unused amount of Tranche B letters of credit. Interest charged for cash borrowings under Tranche A is the greater of Prime Rate plus 1% per annum and the Fed Funds Rate plus 0.5% per annum, or LIBOR plus 3% per annum, depending on the nature of the borrowings. Interest charged for cash borrowings under Tranche B is the greater of Prime Rate plus an applicable margin of 7.25%, or 12% per annum. Beginning September 1, 2002, the applicable margin on Tranche B cash borrowings increases monthly by 0.5% per annum. The Debtors are also required to pay as additional interest, paid in kind, a fee equal to 3% of the average daily outstanding Tranche B cash borrowings, compounded and accrued monthly, and fully payable upon the termination of the Second DIP Facility, provided that, if the termination does not occur prior to September 1, 2002, the amount of such fee 18

increases each month by 1% per annum. The commitment fee on Tranche B is calculated at a rate equal to 4% per annum on the average daily unused cash portion of Tranche B, payable monthly in arrears. In addition, the Debtors are required to pay an extension fee on the Tranche B commitments, payable as follows, if the Second DIP Facility remains outstanding at such dates: 1.2% on September 1, 2002; 1.2% on December 1, 2002 and 1.2% on March 22, 2003. Under the provisions of the Second DIP Facility, the Debtors are required to establish a $5 million interest escrow account. Tranche A and Tranche B fees and interest will be paid from this account. On the earlier of depletion of the escrowed funds or six months after the closing date of the Second DIP Facility, additional funds must be deposited in the escrow account in order to assure that $5 million will be escrowed for this same purpose. In the event of the sale of those certain net assets of Safety-Kleen as described in Note 1, the net proceeds, after reserves for certain selling expenses, interest and fees on the Second DIP facility, shall be applied to prepay the Tranche B loans and the availability under Tranche B will be reduced by $17 million. Net proceeds of certain other asset sales, after reserves for certain selling expenses, interest and fees on the Second DIP facility, are to be used to prepay Tranche A and then Tranche B. The Second DIP Facility benefits from superpriority claim status as provided for under the Bankruptcy Code. Under the Bankruptcy Code, a superpriority claim is senior to unsecured pre-petition claims and all other administrative expenses incurred in a Chapter 11 case. As security, the Second DIP Facility lenders were granted certain priority, perfected liens on certain of the Debtors' assets. Pursuant to the final order approving the Second DIP Facility, such liens are not subordinate to or pari passu with any other lien or security interest (other than (a) liens for certain administrative expenses and (b) liens in favor of Safety-Kleen Corp.'s Chief Executive Officer). As of April 11, 2002, no cash borrowings have been made under the Tranche B facility and approximately $1.4 million has been issued for letters of credit. The Debtors are jointly and severally liable under the Second DIP Facility. Other Domestic Borrowings of Safety-Kleen Senior Credit Facility -- In April 1998, Safety-Kleen repaid its then existing bank credit facility and established a $2.2 billion Senior Credit Facility (the "Senior Credit Facility") pursuant to a credit agreement between Safety-Kleen and a syndicate of banks and other financial institutions. In June 1998, the availability of the Senior Credit Facility was permanently reduced by $325 million to $1.875 billion by the subsequent issuance of the Senior Subordinated Notes described below. The Senior Credit Facility consists of five parts: (i) a $550 million six-year Senior Secured Revolving Credit Facility with a $200 million letter of credit sublimit and $400 million sublimit for loans (the "Revolver"); (ii) a $455 million six-year senior secured amortizing term loan; (iii) a $70 million six-year senior secured amortizing term loan; (iv) a $400 million minimally amortizing seven-year senior secured term loan and (v) a $400 million minimally amortizing eight-year senior secured term loan. The term loans referred to in clauses (ii), (iii), (iv) and (v) are collectively referred to herein as the "Term Loans." Interest costs on the Senior Credit Facility are reset periodically, at least annually, and vary depending on the particular facility and whether Safety-Kleen chooses to borrow under Eurodollar or non-Eurodollar loans. Interest rates applicable to the Senior Credit Facility ranged from 7.56% to 12.88%, including a 2% default premium, effective June 1, 2000. At August 31, 2001, the Term Loans have been drawn in full and borrowings outstanding under the Revolver totaled $340 million. In addition, there were approximately $83.0 million of letters of credit issued under the terms of the Revolver. As a result of the Debtors' Chapter 11 Cases, all additional availability under the Revolver has been terminated, although the letters of credit remain outstanding. Domestic borrowings of Safety-Kleen Services, Inc. (formerly known as LES, Inc.) (the "Domestic Borrower") under the Senior Credit Facility are collateralized by substantially all of the non-hazardous tangible and intangible assets of the domestic subsidiaries of the Domestic Borrower (including subsidiaries of the Company), plus 65% of the capital stock of Safety-Kleen Corp.'s foreign wholly-owned subsidiaries, including but not limited to, Safety-Kleen Corp.'s primary Canadian subsidiaries (collectively, the "Canadian Borrower"). In addition, substantially all of the capital stock of the Domestic Borrower and its wholly-owned or majority-owned domestic subsidiaries is pledged to the Domestic Senior Credit Facility lenders (the "Domestic Lenders") and such domestic subsidiaries guarantee the obligations of the Domestic Borrower to the Domestic Lenders. Senior Subordinated Notes -- On May 29, 1998, the Domestic Borrower, a wholly-owned subsidiary of Safety-Kleen Corp., issued $325 million 9.25% Senior Subordinated Notes due 2008 in a Rule 144A offering. In accordance with an Exchange and Registration Rights Agreement entered at the time of the issuance of the aforementioned notes, Safety-Kleen filed a registration statement with the SEC on June 24, 1998, pursuant to which Safety-Kleen exchanged the 9.25% Senior Subordinated Notes due 2008 for substantially identical notes of Safety-Kleen (the "1998 Notes"). Net proceeds from the sale of the 1998 Notes, after the underwriting fees and other expenses, were approximately $316.8 million. The proceeds were used to repay a portion of the borrowings outstanding under the Senior Credit Facility. The 1998 Notes mature on June 1, 2008. Interest is payable semiannually, on December 1 and June 1. The 1998 Notes will be redeemable, in whole or in part, at the option of Safety-Kleen, at any time and from time to time at a redemption price as defined in the indenture. Upon a change in control of Safety-Kleen, each holder of the 1998 Notes may require Safety-Kleen to repurchase all or a portion of the holder's 1998 Notes at 101% of the principal amount, plus accrued interest. 19

The 1998 Notes are general unsecured obligations of the Domestic Borrower, subordinated in right of payment to all existing and future senior indebtedness, as defined, of the Domestic Borrower. The 1998 Notes will rank senior in right of payment to all existing and future subordinated indebtedness of the Domestic Borrower, if any. The payment of the 1998 Notes are guaranteed on a senior subordinated basis by Safety-Kleen and are jointly and severally guaranteed on a senior subordinated basis by the Domestic Borrower's wholly-owned domestic subsidiaries (including subsidiaries of the Company). No foreign direct or indirect subsidiary or non wholly-owned domestic subsidiary is an obligor or guarantor on the financing. Senior Notes -- On May 17, 1999, Safety-Kleen Corp. issued $225 million 9.25% Senior Notes due 2009 in a Rule 144A offering which were subsequently exchanged for substantially identical notes of Safety-Kleen Corp. in an offering registered with the SEC in September 1999 (the "1999 Notes"). Net proceeds, after the underwriting fees and other expenses, were approximately $219 million and were used to finance the cash portion of the purchase price for the repurchase of the pay-in-kind debenture ("PIK Debenture"), for expenses relating to the repurchase and for general corporate purposes. The 1999 Notes mature on May 15, 2009, with interest payable semi-annually on May 15 and November 15. The 1999 Notes will be redeemable, in whole or in part, at the option of Safety-Kleen, at any time and from time to time at a redemption price as defined in the indenture. Upon a change in control of Safety-Kleen, each holder of the 1999 Notes may require Safety-Kleen Corp. to repurchase all or a portion of such holder's 1999 Notes at 101% of the principal amount thereof, plus accrued interest. The 1999 Notes are unsecured and rank equally with all existing and future senior indebtedness and are senior to all existing and future subordinated indebtedness. The 1999 Notes are not guaranteed by Safety-Kleen Corp.'s subsidiaries. The Senior Credit Facility, the 1998 Notes and the 1999 Notes contain negative, affirmative and financial covenants including covenants restricting debt, guarantees, liens, mergers and consolidations, sales of assets, transactions with affiliates, the issuance of stock to third parties and payment of dividends and establishing a total leverage ratio test, a fixed charge coverage test, an interest coverage ratio test and a maximum contingent obligation to operating cash flow ratio test. As a result of the Chapter 11 Cases, Safety-Kleen, which was not in compliance with the covenants at the time of the Chapter 11 Cases, classified the entire portion of domestic borrowings as liabilities subject to compromise. Promissory Note On May 15, 1997, Safety-Kleen Corp. issued a promissory note in the amount of $60 million to Westinghouse Electric Corporation, subsequently assigned to Toronto Dominion (Texas), Inc. This note, which is specifically identifiable to the Company, bears interest at the variable rate of the six-month London Interbank Offered Rates (6-month LIBOR). Interest on the outstanding principal balance of this note is payable semi-annually on May 30 and November 30 of each year. All outstanding amounts under this note are due in full on May 15, 2003, with mandatory payments of $10 million due on May 15, 2001 and May 15, 2002, which have been stayed as a result of the Chapter 11 Cases. This note is guaranteed by Laidlaw (see Notes 10 and 14). Industrial Revenue Bonds The following industrial revenue bond obligations relate specifically to facilities of the Company: On July 1, 1997, Safety-Kleen Corp. agreed to repay the obligations related to Industrial Revenue Bonds ("IRB") issued by the California Pollution Control Financing Authority in the amount of $19.5 million. Proceeds from these bonds were used to repay prior Pollution Control Revenue Bonds, which were used to finance the acquisition, construction and installation of stabilization treatment units of the Company's hazardous waste landfills in Kern County and Imperial County, California. These bonds mature on July 1, 2007 and bear interest at a rate of 6.70% per annum. Interest payments are due semi-annually beginning on January 1, 1998. On July 1, 1997, Safety-Kleen Corp. guaranteed repayment of all obligations related to the IRB issued by Tooele County Utah in the amount of $45.7 million. Proceeds from these bonds were used to repay prior Tooele County Bonds, which were used to construct and make improvements to the Company's hazardous waste incineration facility located slightly west of Salt Lake City, Utah. These bonds mature on July 1, 2027 and bear interest at a rate of 7.55% per annum. Interest payments are due semi-annually beginning on January 1, 1998. The Company has pledged certain revenues to repay the obligations related to the IRB issued by Tooele County Utah on August 1, 1995, in the amount of $10.0 million. Proceeds from these bonds were used to finance in part, the acquisition, construction and equipping of the Company's hazardous waste disposal and treatment facility. These bonds mature on August 1, 2010 and bear interest at a rate of 6.75% per annum. Interest payments are due semi-annually beginning on February 1, 1996. Repayment of all obligations related to the IRB issued by Tooele County Utah was also guaranteed by Laidlaw (see Notes 10 and 14). Certain assets of the Company secure the obligations related to the IRB issued by The Industrial Development Board of The Metropolitan Government of Nashville and Davidson County on May 1, 1993, in the amount of $15.7 million. Proceeds from these bonds were used to finance in part, the construction, acquisition and installation of modifications and improvements of the Company's hazardous waste facility in Nashville, Tennessee. During fiscal 2001, the bond trustee distributed approximately $10.3 million from the Company's restricted funds (see 20

Note 2) to repay a portion of the outstanding principal. These bonds mature on May 1, 2003 and bear interest at a rate of 6.0% per annum. Interest payments are due semi-annually beginning on November 1, 1993. Repayment of all obligations related to the IRB issued by The Industrial Development Board of The Metropolitan Government of Nashville and Davidson County was also guaranteed by Laidlaw (see Notes 10 and 14). Canadian Borrowings of Safety-Kleen Senior Credit Facility - The Canadian Borrower and Safety-Kleen Corp.'s Canadian subsidiaries participated in the Senior Credit Facility under which it established and initially borrowed $70.0 million (USD) from a syndicate of five banks. The term loan has a floating interest rate based on Canadian prime plus 1.375% or Canadian Bankers Acceptance, ("CB/A") plus 2.375%, at Safety-Kleen's discretion. As a result of the Debtors' Chapter 11 Cases, its Canadian subsidiaries are in default of the loan conditions and a notice of default has been issued by the banks making the loan payable on demand. In accordance with the provisions of default under the Senior Credit Facility, the floating interest rate will increase an additional 2% if all or a portion of any principal of any loan, any interest payable thereon, any commitment fee or any Reimbursement Obligation or Acceptance Reimbursement Obligation, as defined in the Senior Credit Facility, or other amount payable hereunder shall not be paid when due. Accordingly, the outstanding loan balance is classified as a current liability at August 31, 2001 and 2000, and interest continues to accrue at the Canadian Prime Rate plus 3.375%. Operating Facility -- On April 3, 1998, the Canadian Borrower entered into a letter agreement with the Toronto Dominion Bank providing an operating line of credit of up to $35.0 million (CDN). The letter agreement has a floating interest rate based on Canadian prime plus 1.375% or CB/A plus 2.375% for Canadian borrowings and prime plus 1.375% or LIBOR plus 2.375% for U.S. borrowings, at Safety-Kleen's discretion. On March 4, 2000, Toronto Dominion Bank cancelled this letter agreement at which time the Canadian Borrower had borrowings of $17.2 million and letters of credit totaling $3.6 million. The full amount borrowed was in default at August 31, 2001 and 2000, due to breaches of loan covenants by the local subsidiary. Accordingly, the outstanding loan balance is classified as a current liability at August 31, 2001 and 2000. Borrowings by the Canadian Borrower under the Senior Credit Facility and the Operating Facility are collateralized by substantially all of the tangible personal property of Safety-Kleen Corp.'s Canadian subsidiaries and by the guarantees of the Domestic Borrower's domestic, wholly-owned and majority-owned subsidiaries. Additionally, 35% of the common stock of the Canadian Borrower is pledged in favor of the Canadian Senior Credit Facility Lenders and the Canadian Operating Facility Lenders. 8. LIABILITIES SUBJECT TO COMPROMISE The principal categories of claims classified as liabilities subject to compromise under bankruptcy reorganization proceedings are identified below. All amounts below may be subject to future adjustment depending on Bankruptcy Court action, further developments with respect to disputed claims, or other events, including the reconciliation of claims filed with the Bankruptcy Court to amounts included in the Company's records (see Note 1). Additional pre-petition claims may arise from rejection of additional executory contracts or unexpired leases by the Debtors. Under a confirmed plan or plans of reorganization, all pre-petition claims may be paid and discharged at amounts substantially less than their allowed amounts. Recorded liabilities -- On a combined basis, recorded liabilities subject to compromise under Chapter 11 Cases at August 31, 2001 and 2000 consist of the following ($ in thousands): 2001 2000 ---------- ---------- Accrued litigation $ 18,387 $ 20,598 Trade accounts payable 46,912 46,238 Accrued insurance liabilities 1,130 1,109 Environmental liabilities 10,099 8,562 Accrued interest, primarily allocated 26,317 26,307 Allocated Safety-Kleen debt, net 704,511 704,247 Promissory note 60,000 60,000 Industrial revenue bonds 80,603 90,900 Other 11,120 5,393 --------- --------- $ 959,079 $ 963,354 ========= ========= Safety-Kleen made certain adequate protection payments to pre-petition lenders of the Senior Credit Facility. Allocated Safety-Kleen debt is presented net of allocated adequate protection payments of $6.3 million and $6.6 million at August 31, 2001 and 2000, respectively. As a result of the Chapter 11 Cases, principal and interest payments may not be made on pre-petition debt without Bankruptcy Court approval or until a plan or plans of reorganization defining the repayment terms has been confirmed. The total interest on pre-petition debt of Safety-Kleen that was not paid or accrued for the period from June 9, 2000 to August 31, 2001 was $306.2 million. Approximately $111.3 million of the interest not paid or accrued relates to the pre-petition debt of Safety-Kleen allocated or directly related to the Company as described in Note 2. Such interest is not being accrued since it is not probable that it will be treated as an allowed claim. The Bankruptcy Code generally disallows the payment of interest that accrues post-petition with respect to unsecured or undersecured pre-petition liabilities. 21

As discussed in Note 2, all net intercompany balances of the Company, including those as of the Chapter 11 filing date, are included in parent company investment, net, in the accompanying Combined Balance Sheets. Contingent liabilities -- Contingent liabilities as of the Chapter 11 filing date are also subject to compromise. At August 31, 2001, the Company was contingently liable to banks, financial institutions and others for approximately $57.3 million for outstanding letters of credit, which included $0.4 million of performance bonds securing performance of sales contracts and other guarantees in the ordinary course of business. The Company is a party to litigation matters and claims that are normal in the course of its operations. Generally, litigation related to "claims", as defined by the Bankruptcy Code, is stayed. Also, as a normal part of their operations, the Company undertakes certain contractual obligations, warranties and guarantees in connection with the sale of products or services. The outcome of the bankruptcy process on these matters cannot be predicted with certainty. 9. ACQUISITIONS The Company completed four acquisitions of stock and assets during fiscal 1999. These acquisitions have been accounted for under the purchase method of accounting. The total purchase price paid for these acquisitions was $10.7 million and the respective net liabilities acquired was $1.1 million, resulting in goodwill recorded of $11.8 million. The Company made no acquisitions during fiscal 2001 or 2000. 10. COMMITMENTS AND CONTINGENCIES Lease Commitments Safety-Kleen enters into operating leases primarily for real property and vehicles used by the Company under various terms and conditions. As discussed in Note 8, commitments related to operating leases are subject to compromise and additional claims may arise from the rejection of unexpired leases. The contractually stated minimum future lease payments for property and equipment used by the Company consist of the following ($ in thousands): Year ending August 31, 2002 $ 9,419 2003 6,847 2004 4,794 2005 3,885 2006 3,427 Thereafter 5,312 -------- Total minimum payments $ 33,684 -------- Purchase Commitments Effective July 2001, Safety-Kleen entered into an agreement with Unisys Corporation and certain of its affiliates to provide outsourced information technology support functions related to personal computer and related network needs. The agreement provides for a monthly fee estimated at approximately $0.5 million based on, among other things, the actual number of workstations, laptops and servers used. The term of the agreement is for five years. Management has estimated that approximately $0.2 million of the monthly fee relates to providing outsourced information technology functions of the Company. Liability Insurance Safety-Kleen, through premiums paid to Laidlaw (see Note 14), carried general liability, vehicle liability, employment practices liability, pollution liability, directors and officers liability, worker's compensation and employer's liability coverage, as well as umbrella liability policies to provide excess coverage over the underlying limits contained in these primary policies. Effective September 1, 2000, Safety-Kleen obtained its insurance requirements from a third-party insurance company. Safety-Kleen's insurance programs for certain worker's compensation, general liability (including product liability) and vehicle liability are self-insured up to certain limits. Claims in excess of these self-insurance limits are fully insured. For self-insured worker's compensation, general liability (including product liability), property, and vehicle liability, management estimates these liabilities based on actuarially determined estimates of the incurred but not reported claims plus any portion of incurred but not paid claims and premiums. These estimates are generally within a range of potential ultimate outcomes. All employee-related health care benefits are fully self-insured and liabilities 22

include both an accrual for an estimate of the incurred but not reported claims that is calculated using historical claims data and an accrual for the incurred but not paid claims and premiums. The Company's liabilities for unpaid and incurred but not reported claims at August 31, 2001, 2000 and 1999 were $8.0 million, $4.3 million and $4.3 million, respectively, under the current risk management program. Certain product and worker's compensation liabilities have been classified as long-term liabilities based upon actuarial projections of future claims payments. These liabilities at August 31, 2001, 2000 and 1999 were $2.8 million, $1.1 million and $1.1 million, respectively. In addition, $1.1 million of the self-insured liabilities at August 31, 2001 and 2000, respectively, are subject to compromise. While the ultimate amount of claims incurred are dependent on future developments, in management's opinion, recorded reserves are adequate to cover the future payment of claims. However, it is reasonably possible that recorded reserves may not be adequate to cover the future payment of claims and there is no guarantee that the Company or Safety-Kleen will have the cash or funds available to pay any or all claims. Adjustments, if any, to estimates recorded resulting from ultimate claim payments will be recorded in the periods in which such adjustments are known. Employment Agreements Safety-Kleen is party to employment agreements with certain executives of the Company, which provide for compensation and certain other benefits. The agreements also provide for severance payments under certain circumstances. Financial Assurance Matters Under RCRA, TSCA, and analogous state statutes, owners and operators of certain waste management facilities are subject to financial assurance requirements to ensure performance of their closure, post-closure and corrective action obligations. Safety-Kleen Corp. and certain of its subsidiaries as owners and operators of RCRA and TSCA waste management facilities are subject to these financial assurance requirements. Applicable regulations allow owners and operators to provide financial assurance through a surety bond from an approved surety. Under federal regulations and in virtually all states, to qualify as an approved surety for the purposes of providing this type of financial assurance, a surety company must be listed on Circular 570, which is maintained and distributed publicly by the United States Department of the Treasury. In compliance with the law, starting in 1997, Safety-Kleen procured surety bonds issued by Frontier Insurance Company ("Frontier") as financial assurance at numerous locations. Of the total amount of financial assurance required for the Company's locations under the environmental statutes, which approximated $420.0 million as of May 31, 2000, slightly more than 50% of such requirements were satisfied through assurances provided by Frontier in the form of surety bonds. On June 6, 2000, the U.S. Treasury issued notification that Frontier no longer qualified as an acceptable surety on Federal bonds and had been removed from Circular 570 on May 31, 2000. Accordingly, effective May 31, 2000, Safety-Kleen no longer had compliant financial assurance for many of its facilities. Under applicable regulations, Safety-Kleen Corp.'s affected subsidiaries were required to obtain compliant financial assurance within sixty days, and in some states, more quickly (although the surety bonds issued by Frontier no longer qualify as acceptable federal bonds, they remain in place and effective until replaced). Immediately following this U.S. Treasury announcement, Safety-Kleen notified the EPA of its lack of audited consolidated financial statements for fiscal 1999, 1998 and 1997 and the difficulties that certain alleged accounting irregularities would cause Safety-Kleen in attempting to obtain compliant financial assurance for its facilities covered by the Frontier bonds. Safety-Kleen and the EPA also contacted states in which the non-compliant facilities were located and apprised such states of these facts. Safety-Kleen and the EPA, acting on behalf of many, but not all, affected states, then engaged in negotiations resulting in the entry of a Consent Agreement and Final Order ("CAFO"), which the Bankruptcy Court approved on October 17, 2000. Some states referred their enforcement authority to the EPA for purposes of this CAFO and thus are, in effect, parties to the CAFO. Other states entered separate, but similar, consent agreements with Safety-Kleen. Some states have never entered separate written agreements, but have allowed Safety-Kleen to continue operating while it obtains coverage to replace the Frontier bonds. The main component of the EPA CAFO (and of the consent agreements in various states) is a compliance schedule for Safety-Kleen Corp. and its affected subsidiaries to obtain compliant financial assurance for the facilities covered by the Frontier bonds. That schedule has been modified on several occasions since the CAFO was entered and as Safety-Kleen has replaced Frontier at various facilities. Safety-Kleen believes that most, but not all, states that have retained primary jurisdiction on this issue and which have facilities where Frontier has not yet been replaced will accept the July 31, 2002 deadline under the CAFO, discussed below. However, Safety-Kleen has not concluded agreements with all such states. South Carolina has not followed the EPA schedule, as discussed below. Safety-Kleen may seek further extensions from the EPA and the states, but the CAFO does not obligate the EPA and the states to grant such further extensions. Under the CAFO, the EPA reserves the right, in consultation with an affected state, to determine in its discretion and in accordance with applicable law, to modify these requirements. There can be no assurance that Safety-Kleen will be able to complete its replacement of Frontier on a schedule acceptable to the EPA and the states. If it does not, Safety-Kleen could be assessed penalties in addition to those discussed in the next paragraph. 23

The CAFO imposed a penalty on Safety-Kleen Services, Inc. The penalty has grown to approximately $1.6 million as delays have ensued in the replacement of Frontier, and additional states have joined the CAFO (see discussion below). Some states have imposed financial assurance penalties in addition to this amount. Safety-Kleen believes such penalties, if asserted, would total approximately $1.0 million through January 31, 2002. The total asserted and unasserted penalties related to the Company through January 31, 2002, are approximately $1.3 million. The State of South Carolina has not entered any consent agreement with Safety-Kleen that would extend any financial assurance regulatory deadline with respect to the Pinewood Facility. Moreover, South Carolina has not agreed to the July 31, 2002 deadline for the replacement of Frontier at inactive facilities and has notified Safety-Kleen that it is assessing daily penalties that escalate to a maximum of $6,000 per day at an inactive facility in that state that does not yet have coverage to replace Frontier. In the EPA CAFO and in some state consent agreements, Safety-Kleen agreed to a schedule by which the EPA and certain states may monitor Safety-Kleen's efforts to obtain compliant financial assurance. Among other things, the schedule required Safety-Kleen to provide audited restated consolidated financial statements for fiscal years 1997-1999 and the audited consolidated financial statements for fiscal 2000 by certain deadlines. Safety-Kleen did not meet the deadlines by the original due dates but subsequently provided the required information to the EPA and participating states. Accordingly, the EPA and certain states may impose additional penalties on Safety-Kleen, a portion of which may be allocable to the Company. Under the CAFO, until such time as the affected facilities have obtained compliant financial assurance, Safety-Kleen Corp. and its affected facilities must not seek to withdraw an existing irrevocable letter of credit from Toronto Dominion Bank, which is subject to compromise, in the amount of $28.5 million for the benefit of Frontier and shall take all steps necessary to keep current the existing Frontier surety bonds. In the CAFO, Safety-Kleen waived certain arguments they otherwise could have asserted under the Bankruptcy Code with respect to their financial assurance and certain other obligations under environmental laws. Safety-Kleen's lenders and the unsecured creditors committee have reserved their right to assert certain of such arguments. Safety-Kleen understands that, on August 27, 2001, Frontier entered a rehabilitation proceeding that the New York Superintendent of Insurance will administer pursuant to New York law. Safety-Kleen further understands that in such a proceeding, the Superintendent takes possession of the property of Frontier and conducts its business. Safety-Kleen has been informed that these rehabilitation proceedings are unlikely to affect the validity of the remaining Frontier bonds at its facilities; however, there can be no guarantee that the remaining Frontier bonds at Safety-Kleen facilities will continue to be valid. As of January 1, 2002, Safety-Kleen was in a position to replace Frontier at all its active facilities (actual replacement occurs as regulators review and accept the replacement policies Safety-Kleen has little or no control over the timing of this process). The current EPA deadline for replacement of Frontier at inactive facilities of the Company is July 31, 2002. As of August 31, 2001, Safety-Kleen had provided financial assurances for the Company's facilities in the form of insurance policies and performance bonds to the applicable regulatory authorities totaling approximately $440.0 million, in connection with closure, post-closure and corrective action requirements of certain facility operating permits. Letters of credit of approximately $52.9 million are held to meet various financial assurance requirements for the Company. Restricted assets of $22.2 million are held in trust for the Company's landfill closure, post-closure and environmental impairment (see Note 2). Insurance policies with limits of approximately $92.0 million are held to cover any bodily injury or property damage to third parties caused by accidental occurrences at certain of the Company's facilities. Chapter 11 Proceedings As described in Note 1, the Debtors filed voluntary petitions for relief under Chapter 11 of the Bankruptcy Code on June 9, 2000. Management continues to operate the business of the Debtors as debtors-in-possession under Sections 1107 and 1108 of the Bankruptcy Code. In this proceeding, the Debtors intend to propose and seek confirmation of a plan or plans of reorganization. Pursuant to the automatic stay provision of Section 362 of the Bankruptcy Code, virtually all pending pre-petition litigation against the Debtors is currently stayed. As of August 31, 2001, proofs of claim in the approximate amount of $174.0 billion have been filed against the Debtors by, among others, secured creditors, unsecured creditors and security holders. Safety-Kleen is in the process of reviewing the proofs of claim and once this process is complete, will file appropriate objections to the claims in the Bankruptcy Court, including objections on behalf of the Company. As of August 31, 2001, Safety-Kleen believes it has identified approximately $170.8 billion of such claims that are duplicative or without merit. The Company believes that the amount of these claims related to the Company that are in excess of the $959.1 million recorded as liabilities subject to compromise in the accompanying Combined Balance Sheet at August 31, 2001 are: (i) duplicative or without merit; (ii) do not meet the criteria to be recorded as a liability under accounting principles generally accepted in the United States; and (iii) will not have a material effect on the accompanying Combined Balance Sheets, but there can be no assurance that management is correct and these claims may have a material effect on the accompanying Combined Balance Sheets. As a result of the Chapter 11 Cases, Safety-Kleen has not paid certain real estate taxes and certain taxing authorities have asserted liens against certain real estate of the Company. Currently, it is not possible to predict the length of time the Debtors will operate under the protection of Chapter 11, the outcome of the Chapter 11 proceedings in general, or the effect of the proceedings on the business of Safety-Kleen or on the interests of the various creditors and security holders. Under the Bankruptcy Code, post-petition liabilities and pre-petition liabilities subject to compromise must be satisfied 24

before shareholders can receive any distribution. The ultimate recovery to Safety-Kleen Corp.'s shareholders, if any, will not be determined until the end of the case when the fair value of the Debtors' assets is compared to the liabilities and claims against the Debtors. There can be no assurance as to what value, if any, will be ascribed to the Safety-Kleen Corp. common stock in the bankruptcy proceedings. Safety-Kleen Corp. does not believe that its shareholders will receive any distribution upon consummation of a plan or plans of reorganization. Actions Involving Laidlaw Inc. Laidlaw owns 43.6% of the outstanding common stock of Safety-Kleen and has various other arrangements and relationships with Safety-Kleen. On November 7, 2000, Laidlaw, on behalf of itself and its direct and indirect subsidiaries (collectively referred to as the "Laidlaw Group"), filed a proof of claim in the unliquidated amount of not less than $6.5 billion against the Debtors in the Chapter 11 Cases. The Laidlaw Group claims against the Debtors fall into the following general categories: 1) claims for indemnification; 2) contribution and reimbursement in connection with certain litigation matters; 3) claims against the Debtors for fraudulent misrepresentation, fraud, securities law violations, and related causes of action; 4) insurance claims; 5) guaranty claims; 6) environmental contribution claims; 7) tax reimbursement claims; and 8) additional miscellaneous claims. On April 19, 2001, Safety-Kleen Corp. on behalf of itself and its direct and indirect subsidiaries, including those within the Company, filed with the Bankruptcy Court an objection to the proof of claim filed by Laidlaw Group. On April 19, 2001, Safety-Kleen filed an action against Laidlaw and its affiliates, LTI and Laidlaw International Finance Corporation ("LIFC") (collectively the "Laidlaw Defendants") in the Debtors' Chapter 11 Cases, Adv. Pro. No. 01-01086 (PJW). This action seeks to recover a transfer of over $200 million in August 1999 (the "Transfer") made to or for the benefit of the Laidlaw Defendants, holders of 43.6% of Safety-Kleen Corp's common stock. Safety-Kleen asserts that the transfer is recoverable either as a preference payment to the extent the Transfer retired pre-existing debt or as a fraudulent transfer to the extent the Transfer redeemed equity or was made with intent to hinder, delay or defraud creditors. In the action, Safety-Kleen seeks to recover the Transfer, plus interest and costs occurring from the first date of demand from the Laidlaw Defendants. On June 28, 2001, Laidlaw and five of its subsidiary holding companies, Laidlaw Investments Ltd., LIFC, Laidlaw One, Inc., LTI and Laidlaw USA, Inc. (collectively, "Laidlaw Debtors") filed voluntary petitions for reorganization under Chapter 11 of the Bankruptcy Code in the United States Bankruptcy Court for the Western District of New York Case Nos. 01-14099K through 01-1404K. On the same day, Laidlaw and Laidlaw Investments Ltd. filed cases under the Canada Companies' Creditors Arrangement Act (CCAA) in the Ontario Superior Court of Justice in Toronto, Ontario. On October 16, 2001, Safety-Kleen and the Official Committee of Unsecured Creditors filed a proof of claim in the unliquidated amount of not less than $4.6 billion, subject to statutory trebling, plus punitive damages, interest, and costs, against Laidlaw Debtors in the above-referenced Chapter 11 cases. The claims against Laidlaw Debtors fall into the following general categories: 1) claims for fraud, racketeering, breach of fiduciary duty, and other related misconduct; 2) preference and fraudulent transfer claims; 3) breach of contract, misrepresentation, and other related misconduct; 4) guaranty claims; and 5) indemnification, contribution, and reimbursement claims. Laidlaw Debtors have not yet filed an objection to the proof of claim filed by Safety-Kleen. Safety-Kleen intends to vigorously pursue this claim. Similarly, certain directors of Safety-Kleen Corp. filed a proof of claim against Laidlaw Debtors. To the extent these directors are successful in obtaining payments that otherwise would have gone to Safety-Kleen, their interests could be deemed materially adverse to the interests of Safety-Kleen. As a result of Laidlaw Debtors' filings, the claims and causes of action Safety-Kleen may have against Laidlaw Debtors may be subject to compromise in the Laidlaw Debtors' Chapter 11 or CCAA proceedings. In December 2001, pursuant to the Safety-Kleen/Laidlaw Mediation Discovery Protocol, the Debtors, the Debtors' secured lenders, the Debtors' Official Committee of Unsecured Creditors, certain of the Debtors' directors, Laidlaw Debtors and the Laidlaw Debtors creditors' committee and subcommittees agreed to undertake, on an expedited and consolidated basis, limited preliminary discovery to obtain information to assist in presenting submissions to a mediator in an effort to resolve certain outstanding claims between and among the parties in the Debtors' and Laidlaw Debtors bankruptcy cases. A mediation proceeding began in early April 2002. The parties continue discussions. The resolution of these matters could have a material adverse effect on financial condition of Safety-Kleen and the Company. Legal Proceedings Legal proceedings covering a wide range of matters are pending or threatened in the United States and foreign jurisdictions against Safety-Kleen and/or former and/or current officers, directors and employees. Many of these claims directly or indirectly impact the Company. Various types of claims are raised in these proceedings, including shareholder class action and derivative lawsuits, product liability, environmental, antitrust, tax, and breach of contract. Management consults with legal counsel in estimating reserves and developing estimates of ranges of potential loss. Safety-Kleen has claims related to the Company where Safety-Kleen has assessed that an unfavorable outcome is probable. At August 31, 2001, the aggregate estimated potential loss on these claims range from approximately $14.4 million to approximately $62.7 million and the Company has recorded reserves of approximately $20.0 million, comprised of $18.4 million of accrued litigation subject to compromise and $1.6 million of environmental liabilities subject to compromise, representing its best estimate of losses to be incurred. Additionally, Safety-Kleen also has substantial claims related to the Company where Safety-Kleen has assessed that an unfavorable outcome is probable or, at least, reasonably possible and which, if incurred, may have a material adverse effect on Safety-Kleen's and the Company's 25

financial condition. The Company, however, has not recorded reserves related to these claims as management believes the potential loss is not currently estimable. The actual outcomes from these claims, the most significant of which are discussed below, could differ from these estimates. Matters Related to Investigation of Safety-Kleen's Financial Results On March 6, 2000, Safety-Kleen announced that it had initiated an internal investigation (the "Safety-Kleen Investigation") of its previously reported financial results and certain if its accounting policies and practices. This investigation followed receipt by Safety-Kleen Corp.'s Board of Directors of information alleging possible accounting irregularities that may have affected the previously reported financial results of Safety-Kleen. Following this announcement PricewaterhouseCoopers LLP, Safety-Kleen's independent accountants at that time, notified Safety-Kleen that it was withdrawing its previously issued reports of independent public accountants on the fiscal years 1999, 1998 and 1997 consolidated financial statements. The internal investigation included fiscal year 1997 and subsequent periods. The Board appointed a special committee, consisting of four directors who were then independent outside directors of Safety-Kleen Corp., to conduct the internal investigation (the "Special Committee (Investigation)"). The Special Committee (Investigation) was later expanded to five directors, with the addition of one additional independent outside director. The Special Committee (Investigation) engaged the law firm Shaw Pittman, and Shaw Pittman engaged the accounting firm Arthur Andersen LLP, to assist with the comprehensive investigation of these matters. The Board placed Kenneth W. Winger, Safety-Kleen Corp.'s President and Chief Executive Officer and a director, Michael J. Bragagnolo, Executive Vice President and Chief Operating Officer, and Paul R. Humphreys, Senior Vice President of Finance and Chief Financial Officer, on administrative leave on March 5, 2000. Safety-Kleen accepted the resignations of Messrs. Winger, Bragagnolo, and Humphreys, as officers, in mid-May 2000 and of Mr. Winger, as a director, on June 9, 2000, and subsequently terminated the employment of these individuals in July 2000. On September 14, 2000, the Bankruptcy Court approved Safety-Kleen's motion to engage Arthur Andersen LLP (i) to act as its independent public accountants, (ii) to conduct an audit of Safety-Kleen's consolidated financial statements with respect to fiscal years 2000, 1999, 1998 and 1997, (iii) to continue assisting with the Safety-Kleen Investigation and (iv) to provide other services. Safety-Kleen restated its previously reported consolidated financial statements for each of the three years ended August 31, 1999, 1998 and 1997 in Safety-Kleen's Form 10-K/A for the year ended August 31, 2000 filed with the SEC on July 9, 2001. On September 13, 2001, the Board of Directors dissolved the Special Committee (Investigation) and established the Special Committee (Conflicts of Interest in Litigation). The Special Committee (Conflicts of Interest in Litigation) is authorized to manage all litigation involving Safety-Kleen and any member of the Board of Directors. The new committee is comprised of Ronald A. Rittenmeyer, Kenneth K. Chalmers, Peter E. Lengyel and David W. Wallace, each of whom was appointed to the Board subsequent to March 6, 2000 and is not personally involved in such litigation. Beginning in March 2000, a number of lawsuits were filed, on behalf of various classes of investors, including bondholders and shareholders, against Safety-Kleen, certain officers, former directors, and others. The complaints that did name Safety-Kleen were subsequently amended eliminating Safety-Kleen as a defendant and adding certain other defendants, including certain Directors of Safety-Kleen Corp. The complaints allege, among other things, that the defendants made false and misleading statements and violated certain federal securities laws. Generally, the actions seek to recover damages in unspecified amounts that the plaintiffs allegedly sustained by acquiring shares of Safety-Kleen Corp.'s common stock or purchasing debt of Safety-Kleen. Although Safety-Kleen is not a party to these actions, certain of the individual defendants who are present or former officers or directors of Safety-Kleen Corp. have made demands to be indemnified by Safety-Kleen in connection with the action. Shortly after Safety-Kleen's March 6, 2000, announcement, Safety-Kleen representatives met with officials of the SEC and advised the SEC of the alleged accounting irregularities and Safety-Kleen's internal investigation with respect to the allegations. On March 10, 2000, Safety-Kleen was advised that the SEC had initiated a formal investigation of Safety-Kleen. On or about March 22, 2000, Safety-Kleen Corp. was served with a subpoena issued by a Grand Jury sitting in the United States District Court for the Southern District of New York seeking production of documents sought by the SEC in its investigation. Safety-Kleen has responded to the subpoena. Safety-Kleen is cooperating with each of the investigations. On October 4, 2001, Safety-Kleen, along with Robert W. Luba, the Estate of John W. Rollins, Sr., John W. Rollins, Jr., David E. Thomas, Jr., Henry B. Tippie, James L. Wareham, and Grover C. Wrenn filed an action in the Circuit Court of South Carolina, Richland County, against PricewaterhouseCoopers LLP and PricewaterhouseCoopers LLP (Canada), Civil No. 3:01-4247-17 (the "PWC Action"). The PWC Action alleges, among other things, that the defendants were negligent and reckless in failing to comply with applicable industry and professional standards in their review and audit of Safety-Kleen's consolidated financial statements and in the negligent and reckless failure to detect and/or report material misstatements in those consolidated financial statements. The Complaint alleges causes of action for breach of contract, breach of contract accompanied by a fraudulent act, professional negligence, negligent misrepresentation, violations of the South Carolina Unfair Trade Practices Act and a declaratory judgment for indemnification on behalf of the plaintiff directors. The Complaint seeks in excess of $1.0 billion from the defendants. Safety-Kleen intends to pursue this claim vigorously. On November 13, 2001, Safety-Kleen, along with Robert W. Luba, the Estate of John W. Rollins, Sr., John W. Rollins, Jr., David E. Thomas, Jr., Henry B. Tippie, James L. Wareham, and Grover C. Wrenn filed an action in the Circuit Court of South Carolina, Richland County, 26

against National Union Fire Insurance Company of Pittsburgh, PA and American Home Assurance Company, Civil No. 01CP404813 (the "Insurance Action"). The Insurance Action alleges that the defendants wrongfully denied insurance coverage under certain directors and officers insurance policies for the various securities actions detailed above. The Complaint alleges causes of action for declaratory judgment and breach of contract. The Complaint also seeks insurance coverage for plaintiffs' for costs associated with defending the securities actions and for any liability plaintiffs may ultimately incur. Safety-Kleen intends to pursue this claim vigorously. On December 13, 2000, thirteen lenders to Safety-Kleen Services, Inc., sued PricewaterhouseCoopers LLP, in the State Court of Fulton County Georgia, alleging negligent misrepresentation by PricewaterhouseCoopers LLP, in connection with the consolidated financial statements of Safety-Kleen for fiscal years 1997, 1998 and 1999. The case is captioned Toronto Dominion (Texas), Inc., et al. v. PricewaterhouseCoopers LLP, Civil Action No. 00 VS 02679 F. The complaint has been amended twice, and the plaintiffs now number over 90 lenders to Safety-Kleen Services, Inc. On October 23, 2001, PricewaterhouseCoopers LLP, filed a motion for leave to file a third-party complaint naming Safety-Kleen and former Safety-Kleen Corp. officers Kenneth W. Winger, Michael J. Bragagnolo, and Paul B. Humphreys as third party defendants in a third party claim for indemnity or contribution. The Georgia state court granted leave and PricewaterhouseCoopers LLP, has now served a third party complaint against Safety-Kleen. Safety-Kleen is moving to enjoin the third party complaint and argues that it contravenes the automatic stay provisions of federal bankruptcy law. General Environmental The Company's hazardous and industrial waste services are continuously regulated by federal, state, provincial and local laws enacted to regulate the discharge of materials into the environment or primarily for the purpose of protecting the environment. This inherent regulation of the Company necessarily results in its frequently becoming a party to judicial or administrative proceedings involving all levels of governmental authorities and other interested parties. The issues that are involved generally relate to applications for permits and licenses by the Company and their conformity with legal requirements and alleged violations of existing permits and licenses. At April 11, 2002, the Company was involved in four proceedings in which a governmental authority is a party relating primarily to activities at waste treatment, storage and disposal facilities where management believes sanctions involved in each instance may exceed $100,000. The most significant environmental and regulatory proceedings are discussed below: (i) Safety-Kleen (Pinewood), Inc. Safety-Kleen (Pinewood), Inc. ("Pinewood"), an entity included in the accompanying Combined Balance Sheets, owns and operated a hazardous waste landfill, the Pinewood Facility, near the Town of Pinewood in Sumter County, South Carolina. By an order dated May 19, 1994 ("Order"), the South Carolina Board of Health and Environmental Control ("Board") approved the issuance by the Department of Health and Environmental Control ("DHEC") of a RCRA Part B permit (the "Permit") for operation of the Pinewood Facility. The Permit included provisions governing financial assurance and capacity for the facility. The Order established Pinewood's total permitted capacity of hazardous and non-hazardous waste to be 2,250 acre feet, including the amount of hazardous waste disposed prior to the date of the Order. South Carolina law requires that hazardous waste facilities provide evidence of financial assurance for potential environmental cleanup and restoration in form and amount to be determined by DHEC. The Order required Pinewood to establish and maintain the EIF in the amount of $133 million in 1994 dollars ($151 million in 2001 dollars) by July 1, 2004 as financial assurance for potential environmental cleanup and restoration of environmental impairment at the Pinewood Facility. The total fund requirement amount is to be adjusted annually by the Implicit Price Deflator for the Gross National Product as published by the U.S. Department of Commerce. The EIF has two components: (i) the GSX Contribution Fund, which was to be funded by Pinewood in annual cash payments over a ten year period; and (ii) the State Permitted Sites Fund, a legislatively created fund derived from fees on waste disposal at the Pinewood Facility. Under the Order, at the end of the 100-year post-closure care period, funding of the GSX Contribution Fund will be subject to evaluation by an independent arbitrator, who will determine what level of funding, if any, is still required. Safety-Kleen is entitled to seek recovery of any excess amount so determined. Upon termination of the GSX Contribution Fund, any remaining trust assets would revert to Pinewood. In 1993 and 1994, Pinewood paid approximately $15.5 million cash into the GSX Contribution Fund, which has grown to approximately $20.2 million as of August 31, 2001. In June 1995, the South Carolina legislature approved regulations (the "Regulations") governing financial assurance for environmental cleanup and restoration. The Regulations gave owner/operators of hazardous waste facilities the right to choose from among six options for providing financial assurance. The options included insurance, a bond, a letter of credit, a cash trust fund and a corporate guaranty, subject to a financial soundness test. From June 1995, under authority of the Regulations, Pinewood submitted financial assurance for potential environmental cleanup and restoration by way of a corporate guaranty by Laidlaw or insurance. Pinewood also left in place the GSX Contribution Fund. On September 15, 1995, DHEC issued a declaratory ruling finding that the Regulations were applicable to the financial assurance requirements for Pinewood. Pinewood appealed the May 19, 1994, DHEC order and the opposing parties appealed the May 19, 1994, DHEC Order and the September 15, 1995, DHEC declaratory ruling and the appeals were consolidated in the South Carolina Circuit Court in the case captioned Laidlaw Environmental Services of South Carolina, Inc. et al., Petitioners vs. South Carolina Department of Health and Environmental Control and South Carolina Board of Health and Environmental Control, Respondents - Energy Research Foundation, et al., Intervenors, Docket Numbers 27

C/A 94-CP-43-175, 94-CP-43-178, 94-CP-40-1412 and 94-CP-40-1859. The opposing parties included Citizens Asking for a Safe Environment, Energy Research Foundation, County of Sumter, Sierra Club, County of Clarendon, Senator Phil Leventy, the South Carolina Department of Natural Resources and the South Carolina Public Service Authority. The South Carolina Court of Appeals issued a decision on April 4, 2000 (substituting for a January 17, 2000 ruling) ruling that (i) the Regulations were invalid due to insufficient public notice during the promulgation procedure and ordering Pinewood to immediately comply with the cash financial assurance requirements of the May 19, 1994 Order; and (ii) both non-hazardous and hazardous waste count against Pinewood's capacity from the beginning of waste disposal, thereby reducing the remaining permitted capacity. On June 13, 2000, the South Carolina Supreme Court denied Pinewood's petition for a writ of certiorari. On June 14, 2000, DHEC sent notice by letter to the Pinewood Facility directing that Pinewood cease accepting waste for disposal in 30 days and submit a closure plan. DHEC based this directive on the decision of the Court of Appeals that all non-hazardous waste disposed at Pinewood should be counted against Pinewood's hazardous waste capacity limit and DHEC's resulting conclusion that there is no remaining permitted capacity at Pinewood. On June 22, 2000, DHEC notified Pinewood that the Court of Appeals' decision vacated the Regulations and, therefore, Pinewood has the sole responsibility to provide cash funding into the EIF in accordance with the May 19, 1994 Order. The DHEC notice also directed Pinewood to provide information to DHEC within 15 days on how Pinewood would comply with the Order including payment into the GSX Contribution Fund. As of August 31, 2001, there was approximately $20.2 million in the GSX Contribution Fund and approximately $14.7 million in the State Permitted Sites Fund. In 2001 dollars, the total EIF funding requirement is approximately $151.3 million. To comply with the financial assurance provisions of the Order, Pinewood would have to contribute the following payments (in 2001 dollars) as follows, subject to the automatic stay provisions discussed below ($ in thousands): Amount due during fiscal year: 2002 $ 109,811 2003 6,625 --------- Total $ 116,436 ========= Additionally, on June 9, 2000 (on the same day, but after, Pinewood filed its petition for bankruptcy protection in the Bankruptcy Court), DHEC issued an Emergency Order finding that Frontier (the issuer of the bonds used by Pinewood to provide for financial assurance for the costs of closure and post-closure, and third party liability) no longer met regulatory standards for bond issuers. Based on this finding, DHEC ordered Pinewood to cease accepting waste for disposal by August 28, 2000, unless it could provide acceptable alternative financial assurance by June 27, 2000. On July 7, 2000, in the legal action captioned: In re: Safety-Kleen Corp., et al. Debtor, Chapter 11 Cases, Delaware Bankruptcy Court, Case Nos. 00-203 (PJW), Adversary Proceeding No. 00-698-Safety-Kleen (Pinewood), Inc. v. State of South Carolina, et al., District of South Carolina (MJP) Case No. 3:00-2243-10, Pinewood commenced legal proceedings in the United States District Court for the District of Delaware challenging DHEC's June 9, 2000, Emergency Order and DHEC's June 14 and June 22, 2000 notice letters. Pinewood sought to stay and/or enjoin DHEC and the State of South Carolina from enforcement of these directives on the grounds that the actions of DHEC were invalid under various provisions of the United States Constitution, violated the automatic stay provision of the Bankruptcy Code and/or should be enjoined under the equitable powers of the Bankruptcy Court. As an alternative cause of action, Pinewood demanded that it be compensated for the taking of its property without just compensation under provisions of the Constitutions of the United States and the State of South Carolina. On July 12, 2000, the Delaware U.S. District Court issued an Order transferring the case to the United States District Court for the District of South Carolina. On August 25, 2000, the U.S. District Court for the District of South Carolina issued rulings that (i) denied South Carolina's motion to dismiss Pinewood's claims upon jurisdictional grounds and certified the issue for an immediate appeal to the United States Court of Appeals for the Fourth Circuit; (ii) held that the June 9, 2000 Emergency Order was subject to the automatic stay provisions of Section 362 of the Bankruptcy Code; and (iii) denied Pinewood's motion for a preliminary injunction with respect to the June 14, 2000 DHEC letter. The State of South Carolina and Pinewood appealed the District Court's ruling to the United States Court of Appeals for the Fourth Circuit. On December 19, 2001, the United States Court of Appeals for the Fourth Circuit issued its decision on the appeals from Pinewood and DHEC. The Fourth Circuit (i) affirmed the District Court's ruling that Pinewood's action was not barred for failing to state a claim, or on other jurisdictional grounds, (ii) reversed the District's Court's ruling as to the automatic stay, holding that the automatic stay does not apply to DHEC's efforts to enforce the financial assurance requirements, and (iii) affirmed the District Court's denial of Pinewood's motion for a preliminary injunction. On January 22, 2002, DHEC issued a letter to Pinewood directing that various investigative and other actions be taken with respect to the landfill and current Pinewood operating procedures. On January 29, 2002, DHEC issued a letter to Pinewood requiring that it submit a closure plan within 30 days. Pinewood has appealed both the January 22 and January 29 directives while at the same time continuing discussions with DHEC to resolve all open issues. On March 11, 2002, DHEC advised Pinewood that it had submitted a conceptual closure plan that met the intent of DHEC's January 29, 2002 letter. There can be no assurance that these matters will be resolved in favor of the Company and there can be no assurance as to whether the outcome may have a material adverse effect on the Company's financial position. 28

(ii) Ville Mercier Facility On January 12, 1993, Safety-Kleen Services (Mercier) Ltd. ("the Subsidiary"), an entity included in the accompanying Combined Balance Sheets, filed a declaratory judgement action (Safety-Kleen Services (Mercier) Ltd. v. Attorney General of Quebec; Pierre Paradis, in his capacity as Minister of the Environment of Quebec; Ville Mercier; and LaSalle Oil Carriers, Inc.) in the Superior Court for the Province of Quebec, District of Montreal. The legal proceeding seeks a court determination of the liability associated with the contamination of former lagoons that were located on the Company's Ville Mercier property. The Subsidiary asserts that it has no responsibility for the contamination on the site. The Minister filed a Defense and Counterclaim in which it asserts that the Subsidiary is responsible for the contamination, should reimburse the Province of Quebec for past costs incurred in the amount of $17.4 million (CDN), and should be responsible for future remediation costs. The legal proceedings are in the discovery stage. The contamination on the Ville Mercier facility dates back to 1968, when an unrelated company owned the property. In 1968, the Quebec government issued two permits to the unrelated company to dump organic liquids into lagoons on the Ville Mercier property. By 1972, groundwater contamination had been identified and the Quebec government provided an alternate water supply to the municipality of Ville Mercier. Also in 1972, the permit authorizing the dumping of liquids was terminated and a permit to operate an organic liquids incinerator on the property was issued. (The entity to which this permit was issued was indirectly acquired by Safety-Kleen Corp. in 1989.) In 1973, the Quebec government contracted with the incinerator operator to incinerate the pumpable liquids in the lagoons. In 1980, the incinerator operator removed, solidified and disposed of the non-pumpable material from the lagoons in a secure cell and completed the closure of the lagoons at its own expense. In 1983, the Quebec government constructed and continues to operate a groundwater pumping and treatment facility near the lagoons. Safety-Kleen believes that the Subsidiary is not the party responsible for the lagoon and groundwater contamination and the Subsidiary has denied any responsibility for the decontamination and restoration of the site. In November 1992, the Minister of the Environment ordered the Subsidiary to take all the necessary measures to excavate, eliminate or treat all of the contaminated soils and residues and to recover and treat all of the contaminated waters resulting from the aforementioned measures. The Subsidiary responded by letter, reiterating its position that it had no responsibility for the contamination associated with the discharges of wastes into the former Mercier lagoons between 1968 and 1972 and proposing to submit the question of responsibility to the Courts for determination as expeditiously as possible through the cooperation of the parties' respective attorneys, resulting in the filing of the pending action. On or about February 9 and March 12, 1999, Ville Mercier and three neighboring municipalities filed separate legal proceedings against the Subsidiary and certain related companies together with certain former officers and directors, as well as against the Government of Quebec (Ville Mercier v. Safety-Kleen Services (Mercier) Ltd., et. al.; Ville de Chateauguay v. Safety-Kleen Services (Mercier) Ltd., et. al.; Municipality of Ste-Martine v. Safety-Kleen Services (Mercier) Ltd., et. al.; and St.Paul de Chateauguay v. Safety-Kleen Services (Mercier) Ltd., et. al.). The lawsuits assert that the defendants are jointly and severally responsible for the contamination of groundwater in the region, which Plaintiffs claim was caused by contamination from the former Ville Mercier lagoons, and which they claim caused each municipality to incur additional costs to supply drinking water for their citizens since the 1970's and early 1980's. The four municipalities claim a total of $1.6 million (CDN) as damages for additional costs to obtain drinking water supplies and seek an injunctive order to obligate the defendants to remediate the groundwater in the region. The Subsidiary will continue to assert that it has no responsibility for the ground water contamination in the region. The legal proceedings are in the discovery stage. (iii) Marine Shale Processors Beginning in the mid-1980's and continuing until July 1996, Marine Shale Processors, Inc., located in Amelia, Louisiana ("Marine Shale"), operated a kiln which incinerated waste producing a vitrified aggregate as a by-product. Marine Shale contended that its operation recycled waste into a useful product, i.e. vitrified aggregate, and therefore, was exempt from RCRA regulation and permitting requirements as a Hazardous Waste Incinerator. The EPA contended that Marine Shale was a "sham-recycler" subject to the regulation and permitting requirements as a Hazardous Waste Incinerator under RCRA, that its vitrified aggregate by-product is a hazardous waste, and that Marine Shale's continued operation without required permits was illegal. Litigation between the EPA and Marine Shale with respect to this issue began in 1990 and continued until July 1996 when Marine Shale was ordered to shut down its operations by U.S. Fifth Circuit Court of Appeals. During the course of its operation, Marine Shale produced thousands of tons of aggregate, some of which was sold as fill material at various locations in the vicinity of Amelia, Louisiana, but most of which is stockpiled on the premises of the Marine Shale facility. Moreover, as a result of past operations, soil and groundwater contamination may exist on the Marine Shale site. In November 1996, an option to buy Marine Shale was obtained by Earthlock Technologies, Inc. ("Earthlock") formerly known as GTX, Inc. with the intent to operate the facility as a permitted Hazardous Waste Incinerator. Subsequently, Marine Shale, Earthlock and the EPA reached a settlement, including a required cleanup of the aggregate and the facility, and the Louisiana Department of Environmental Quality issued a draft permit to Earthlock for operation of the Marine Shale facility as a RCRA-permitted Hazardous Waste Incinerator. Opposition parties filed appeals and in October 1999, a Louisiana State Court Judge ruled that the draft permit was improperly issued. Earthlock appealed this decision and in October 2000, the Appeals Court reversed the lower court and affirmed the permit issuance. The opposition parties filed applications for Supervisory Writs with the Louisiana Supreme Court, and these applications were denied in April 2001. There may be further 29

legal challenges to the permit and it is uncertain whether or when Earthlock will exercise its purchase option and begin operation of the Marine Shale facility. The Company was one of the largest customers of Marine Shale. In the event Marine Shale does not operate, the potential exists for an EPA action requiring cleanup of the Marine Shale site and the stockpiled aggregate under CERCLA. In this event, the Company would be exposed to potential financial liability for remediation costs as a PRP under CERCLA. (iv) RayGar Environmental Systems International Litigation On August 7, 2000, RayGar Environmental Systems International, Inc. filed its First Amended Complaint in the United States District for the Southern District of Mississippi, Hattiesburg Division, Civil Action No. 2:9CV376PG, against Laidlaw, Laidlaw Investments, Ltd., LTI, LESI, LES, Inc. (a wholly-owned subsidiary of Safety-Kleen Corp. now known as Safety-Kleen Services, Inc.), Laidlaw Environmental Services (U.S.), Inc. (an indirect wholly-owned subsidiary of Safety-Kleen Corp. and predecessor to Safety-Kleen Services, Inc.), Laidlaw OSCO Holdings, Inc. (a wholly-owned subsidiary of Safety-Kleen Corp. now known as Safety-Kleen OSCO Holdings, Inc., a company included in the accompanying Combined Balance Sheets), Laidlaw International, and Safety-Kleen Corp. alleging a variety of Federal antitrust violations and state law business torts. RayGar seeks damages it has allegedly sustained as a result of the defendants' actions in an amount of not less than $450 million in actual compensatory damages and not less than $950 million for punitive damages. The dispute arises from an unsuccessful effort pursuant to an agreement between RayGar and Safety-Kleen, to obtain RCRA and related permits for the operation of a wastewater treatment facility in Pascagoula, Mississippi. The action has not proceeded against Safety-Kleen due to the Chapter 11 Cases. (v) Federated Holdings, Inc. Litigation On November 6, 2000, Federated Holdings, Inc. (FHI) filed a lawsuit against Laidlaw, Laidlaw Investments, Ltd., LTI, LESI (now Safety-Kleen Corp.), LES, Inc., Laidlaw OSCO Holdings, Inc. (a wholly-owned subsidiary of Safety-Kleen now known as Safety-Kleen OSCO Holdings, Inc., and a company included in the accompanying Combined Balance Sheets), Laidlaw International, and Safety-Kleen Corp. in the United States District Court for the Southern District of Mississippi, Hattiesburg Division, Civil Action No. 2:00CV286 alleging a variety of Federal antitrust violations and state law business torts. FHI seeks damages it has allegedly sustained as a result of the defendants' actions in an amount of not less than $200 million in actual compensatory damages and not less than $250 million for punitive damages. The dispute arises from an unsuccessful effort pursuant to an agreement between FHI and a Safety-Kleen Corp. subsidiary to obtain RCRA and related permits for the operation of a hazardous waste landfill in Noxubee County, Mississippi. The action has not proceeded against Safety-Kleen due to the Chapter 11 Cases. (vi) Hudson County Improvement Authority Litigation In July 1999, Hudson County Improvement Authority ("HCIA") filed suit in the Superior Court, Hudson County, New Jersey against SK Services (East), L.C. ("SK Services East") (a company included in the accompanying Combined Balance Sheets), Safety-Kleen, American Home Assurance Company, and Hackensack Meadowlands Development Commission. An Amended Complaint was filed on August 18, 1999, in which HCIA sought damages and injunctive relief evicting SK Services East from a 175-acre site in Kearny, New Jersey owned by HCIA. SK Services East had been using the site pursuant to an Agreement and Lease dated as of February 2, 1997 (the "Agreement and Lease") for the processing and disposal of processed dredge material. HCIA alleged that certain conditions precedent to SK Services East's right to continue operations at the site had not occurred, that as a result the Agreement and Lease had automatically terminated, that SK Services East owed HCIA approximately $11 million in back rent, and that SK Services East was obligated to finish the remediation of the site and its preparation for development as a commercial property. In January 2000, the Court granted HCIA summary judgment on its motion to declare the Agreement and Lease null and void as a result of the failure of the conditions precedent. This ruling effectively terminated the relationship between SK Services East and HCIA leaving only the issue of the determination of the rights and responsibilities of the parties in the unwinding of the relationship. In May 2000, HCIA filed for summary judgment seeking an order declaring that SK Services East is obligated to complete all measures required under the Remedial Action Work Plan for the site. SK Services East filed a brief opposing the motion. In June 2000, HCIA withdrew its pending motion, with the Court's understanding that the motion could be re-filed if the automatic stay in connection with Debtor's Chapter 11 bankruptcy protection is lifted. On July 11, 2001 the Bankruptcy Court entered an Order authorizing Debtor's rejection of the executory contracts and the unexpired lease to which SK Services East and HCIA were parties. The Order does not limit, abridge, or otherwise effect HCIA's right to assert and seek remedies regarding its pre- and/or post-petition claims against Safety-Kleen for damages and other relief. Also on July 11, 2001 the Bankruptcy Court granted HCIA's motion to modify the Bankruptcy Code's automatic stay, and entered an Order permitting the Superior Court of New Jersey, Hudson County, to make its final determination regarding SK Services East contractual obligations under the Agreement and Lease. The Superior Court held oral argument on this matter in September 2001 and advised the parties that the Court wanted the parties to make good faith efforts to reach an agreement as to the remaining obligations before the Court issues a decision. Representatives of all the parties involved in the remediation development activities at the Kearny, NJ site met on December 5, 2001 for preliminary discussions of a final resolution of all open issues. The Company has recorded its expected remaining liability related to the rejected lease as a component of liabilities subject to compromise in the accompanying Combined Balance Sheets at August 31, 2001. 30

(vii) ECDC Environmental, L.C. Claim The Company entered into a long-term contract (the "4070 Contract") with General Motors Corporation ("GM") to manage certain GM waste products. One requirement of the 4070 Contract was to provide a dedicated cell for GM waste products at a landfill facility owned by ECDC Environmental, L.C. ("ECDC"), which was then a Safety-Kleen Corp. subsidiary. In November 1997, Safety-Kleen Corp. sold its interest in ECDC to an affiliate of Allied Waste Industries, Inc. Pursuant to the sale, ECDC, the Company entered the GM Waste Disposal Agreement (the "WDA") governing the obligations of the parties with respect to the continued management of GM waste in the dedicated cell at the ECDC landfill. By letter dated May 15, 2000, Safety-Kleen was notified of GM's intent to terminate the 4070 Contract for default, effective December 31, 2000. Under the WDA, default by the Company under the 4070 Contract would have obligated the Company to pay certain costs, rebates and damages to ECDC in accordance with the terms of the WDA. The Debtors, including the Company, which were parties to the 4070 Contract and the WDA, filed for protection under Chapter 11 of the Bankruptcy Code. In anticipation of the Company's rejection of the 4070 Contract pursuant to 11 U.S.C. (s)365, on October 30, 2000, ECDC filed a claim for not less than approximately $11 million plus other additional, and unspecified damages for the Company's breach of the 4070 Contract and WDA. Subsequently, the Bankruptcy Court granted the motion by Safety-Kleen and certain of its subsidiaries, which were parties to the 4070 Contract and the WDA, to reject both the 4070 Contract and the WDA, effective December 1, 2000. (viii) Bryson Adams Litigation In 1996, a lawsuit was filed in the federal court in Baton Rouge, Louisiana, under the caption Carleton Gene Rineheart et al. v. CIBA-GEIGY Corporation, et al., U.S. District Court for the Middle District of Louisiana, CA #96-517, Section B(2). In October 1999, a substantially similar lawsuit was filed in state court in Lafayette Parish, Louisiana, under the caption of Bryson Adams, et al. v. Environmental Purification Advancement Corporation, et al., Civil Action No. 994879, Fifteenth Judicial District Court, Parish of Lafayette, State of Louisiana. In December 2000, these two cases were consolidated with Adams designated as the lead case. In this consolidated litigation, plaintiffs are suing for alleged personal injury and/or property damage arising out of the operation of certain waste disposal facilities near Bayou Sorrel, Louisiana. The initial Bryson Adams lawsuit was filed on behalf of 320 plaintiffs against 191 defendants. The Company owns and operates a hazardous waste deep injection well in Bayou Sorrel, Louisiana and is named as a defendant. The Company is also named as a defendant for its alleged role as a generator and arranger for disposal or treatment of hazardous waste at certain of the disposal facilities, which are named in the litigation. It is alleged that the Company was the operator of the injection well in question from 1974 through the present. In addition to the claims asserted by the plaintiffs, there is the potential that the customers of the injection well, who are also defendants, may assert claims for indemnification against the Company. The action has not proceeded against the Company due to the filing of their Chapter 11 Cases on June 9, 2000. (ix) FUSRAP Waste Disposal at Safety-Kleen (Buttonwillow), Inc. Safety-Kleen (Buttonwillow), Inc., a company included in the accompanying Combined Balance Sheets, owns and operates a hazardous waste landfill in Kern County, California. The facility accepted and disposed of construction debris that originated at a site in New York, which was part of the federal Formerly Utilized Sites Remediation Program (FUSRAP). The construction debris was low-activity radioactive waste and was shipped to the site by the U.S. Army Corps of Engineers (USACE). FUSRAP was created in the mid-1970s in an attempt to manage various sites around the country contaminated with residual radioactivity from activities conducted by the Atomic Energy Commission and United States military during World War II. The California Department of Health Services (DHS) has claimed that the facility did not lawfully accept the waste. Both DHS and the Department of Toxic Substances Control (DTSC) have filed claims in the Debtor's Chapter 11 Cases preserving the right of the agencies to seek penalties and possibly compel removal of the material should an ongoing investigation reveal the subsidiary acted improperly. DHS claimed penalties in the amount of $0.6 million and potential removal costs of $15.5 million should DHS have to oversee and/or conduct the removal. The proof of claim filed by the DTSC was in the amount of $15.0 million for potential penalties plus an unspecified amount for any costs the DTSC may incur should the subsidiary be forced to remove the waste. Safety-Kleen (Buttonwillow), Inc. and the USACE contend the material was properly disposed of and will vigorously resist the imposition of any penalties or any efforts to require that waste be removed. 11. DISCLOSURE ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS Carrying amounts reported in the accompanying Combined Balance Sheets for cash and cash equivalents, accounts receivable, accounts payable and accrued other liabilities approximate fair value due to the short-term nature of these instruments. Long-term investments - The fair value of the restricted funds held by trustees approximates carrying value (see Note 2). Long-term debt - Due to the uncertainty resulting from the Chapter 11 Cases discussed in Note 1, the fair value of the Safety-Kleen's long-term debt at August 31, 2001 and 2000 is not determinable. The fair value of Safety-Kleen's long-term debt at August 31, 1999 also cannot be determined. Therefore, fair value of the amounts allocated to the Company at August 31, 2001, 2000 and 1999 are not determinable. 31

Fair value estimates are made at a specific point in time based on relevant market information about the financial instruments. These estimates are subjective in nature and involve uncertainties and matters of significant judgement and therefore, cannot be determined with precision. Changes in assumptions could significantly affect these estimates. 12. EMPLOYEE BENEFIT PLANS Defined benefit plans As of August 31, 2001, Safety-Kleen did not sponsor any significant active defined benefit pension plans for employees of the Company. For plans terminated during fiscal 2000, all accumulated benefits have been distributed to plan participants. Upon completion of the Rollins Acquisition, the plan sponsor requested permission from all interested parties to terminate the Rollins pension plan. The labor union organizations representing the Rollins employees declined to grant their permission. Safety-Kleen formed a "mirror image" plan, a plan identical in all respects, to the then existing Rollins pension plan. The mirror image plan was named the LES Union Pension Plan, and the union-represented participants and their related accumulated benefit obligations were transferred to the new plan. Accumulated plan benefits were not affected by the transfer. Participants without union affiliations remained in the Rollins pension plan which was formally terminated in July 1997 and the final settlement was paid in September 1998. In January 1998, certain union organizations granted their permission to terminate the LES Union Pension Plan and, during July 1998, the application for determination upon termination was filed with the Internal Revenue Service. The final settlement payout for the LES Union Pension Plan was made in May 1999. All remaining participants represented by union organizations not granting termination permission were transferred to another "mirror image" plan, the Deer Park Union Pension Plan, effective February 1, 1998. In March 1999, management obtained the remaining union organizations' permission to terminate the Deer Park Union Pension Plan. Plan assets were distributed to participants in March 2000. Changes in the projected benefit obligations and pension plan assets relating to the Company's defined benefit pension plans at August 31, 2001, 2000 and 1999, are set forth in the following table ($ in thousands): 2001 2000 1999 ------------ ------------ ----------- Change in benefit obligation - ---------------------------- Net benefit obligation at beginning of year $ -- $ 3,312 $ 22,395 Service cost 58 Interest cost -- -- 102 Curtailment gain -- -- (775) Settlement loss -- 1,851 8,322 Benefits paid -- (5,163) (26,790) ------------ ------------ ----------- Net benefit obligation at end of year -- -- 3,312 ------------ ------------ ----------- Change in plan assets - --------------------- Fair value of plan assets at beginning of year 387 3,742 21,994 Net plan assets acquired -- -- -- Actual return on plan assets 26 1,808 3,329 Contributions 17 -- 5,209 Benefits paid (44) (5,163) (26,790) Commissions, fees and expenses (44) -- -- ------------ ------------ ----------- Fair value of plan assets at end of year 342 387 3,742 ------------ ------------ ----------- Accrued benefit surplus $ 342 $ 387 $ 430 ============ =========== =========== Effective as of October 14, 1997, Safety-Kleen adopted a Supplemental Executive Retirement Plan (SERP) for certain eligible employees. The SERP is an unfunded plan that provides for benefit payments in addition to those payable under a qualified retirement plan. At August 31, 2001, 2000 and 1999, a liability of approximately $1.3 million, $0.5 million and $0.1 million, respectively, related to the employees of the Company included in the SERP plan, is recorded in other long-term liabilities. Defined contribution plan The Company offers to all eligible employees the opportunity to participate in Safety-Kleen's defined contribution employee benefit plan (the "Safety-Kleen 401(k) Plan"). Employees are allowed to contribute up to 15% of their annual salary to the Safety-Kleen 401(k) Plan, and during fiscal 2001, the Company made matching contributions limited to 75% of the first 6% of an employee's eligible compensation. In fiscal 2002, the Board of Directors of Safety-Kleen Corp. has determined to suspend matching contributions indefinitely. Stock-based compensation 32

Certain of the Company's employees participate in stock option plans that are sponsored by and associated with the stock of Safety-Kleen Corp. At August 31, 2001, the Company's employees held 318,425 options with exercise prices ranging from $11.50 to $23.00. 13. INCOME TAXES The Company is comprised of specific internal business units of Safety-Kleen, included within certain domestic, Canadian and Mexican subsidiaries and therefore does not report on a consolidated basis for tax purposes. Accordingly, for purposes of the accompanying Combined Balance Sheets, the current income tax liability and the deferred tax assets and liabilities have been presented using the separate return method as allowed by SFAS 109, "Accounting for Income Taxes". Differences, if any, between the amounts included in the accompanying Combined Balance Sheets and the amounts recorded by the Company entities participating in Safety-Kleen's tax sharing arrangement have been included in parent company investment, net in the accompanying Combined Balance Sheets. Deferred tax assets and liabilities at August 31, 2001, 2000 and 1999 consisted of the following ($ in thousands): 2001 2000 1999 ----------- ---------- ---------- Deferred tax assets: Allowance for uncollectible invoices $ 6,993 $ 4,579 $ 1,789 Deferred revenue 2,375 11,871 16,213 Accrued liabilities 127,004 101,368 74,657 Tax attribute carryovers 242,281 179,221 115,258 Deferred financing costs 4,226 5,313 -- Excess of tax basis over book basis 11,174 18,179 -- Other 1,066 635 -- =========== ========= ========== Total gross deferred tax assets 395,119 321,166 207,917 Less -Valuation allowance (339,535) (297,530) (128,485) ----------- --------- ---------- Net deferred tax assets 55,584 23,636 79,432 ----------- --------- ---------- Deferred tax liabilities: Excess of book basis over tax basis (32,481) (34,556) (94,856) Interest (43,421) (8,629) -- Other (23,240) (23,228) (18,607) ----------- ---------- ---------- Total gross deferred tax liabilities (99,142) (66,413) (113,463) ----------- ---------- ---------- Net deferred tax liabilities $ (43,558) $ (42,777) $ (34,031) =========== ========== ---------- The reported deferred tax attributes differ from the Company's actual tax attributes as they have been adjusted to consider the allocations used to prepare the accompanying Combined Balance Sheets. As of August 31, 2001, the Company's allocable share of Safety-Kleen's net operating loss ("NOL") carryforwards for U.S. federal income taxes was approximately $487 million expiring in the years 2006 through 2021. Such NOLs are subject to limitations of both Treasury Regulation 1.1502-21 and Internal Revenue Code "IRC" Section 382. At August 31, 2001, the Company's allocable share of Safety-Kleen's interest carryovers of approximately $8.9 million limited by IRC Section 163(j) are available against U.S. federal tax without expiration. The NOL carryforwards are based on tax returns as currently filed and are subject to change based on Safety-Kleen's detailed review and analysis of all restatement adjustments for tax purposes, as it is not practicable to determine the impact or related interest and penalties, if any, of the restatement adjustments on amended returns at this time. Safety-Kleen's tax returns are subject to periodic audit by the various jurisdictions in which it operates. These audits, including those currently underway, can result in adjustments of taxes due or adjustments of the NOLs, which are available to offset future taxable income. Implementation of a plan or plans of reorganization will likely reduce the availability of some or all of these NOL carryforwards. Valuation allowances have been established for uncertainties in realizing the benefit of certain tax loss carryforwards and other deferred tax assets. In assessing the realizability of carryforwards and other deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The valuation allowance is adjusted in the period management determines it is more likely than not that deferred tax assets will or will not be realized. Until May 1997, Safety-Kleen was included in the consolidated U.S. tax returns filed by Laidlaw. As such, Safety-Kleen is jointly and severally liable for any taxes due with respect to those returns. Accordingly, Safety-Kleen and the Company could be responsible for taxes relating to adjustments to the 1997 and prior consolidated tax returns of Laidlaw. 33

14. RELATED PARTY TRANSACTIONS Corporate The Company receives certain support services consisting primarily of legal, accounting, finance and information technology through Corporate. Costs incurred by Corporate that can reasonably be associated with the Company are allocated using methods which management believes reflect the cost of services performed. The allocations were based on a specific identification of Corporate costs attributable to the Company and, to the extent that such identification was not practicable, based on the Company's estimate of how Corporate resources were consumed. Safety-Kleen believes these allocations have been effected on a systematic and rational basis. These allocations are included in intercompany account balances between the Company, BSSD and Corporate. Accordingly these balances are included in parent company investment, net in the accompanying Combined Balance Sheets. Branch Sales and Service Division The Company provides a variety of services to BSSD, including the collection, treatment and disposal of hazardous and non-hazardous wastes. The Company believes that charges to BSSD for these services approximate market prices. In addition, the Company charges the BSSD for services provided to the BSSD, including engineering and environmental accounting services. The Company sends certain waste streams to the BSSD recycle centers and kilns and is charged amounts the Company believes approximate market prices. Net amounts due to or due from the BSSD are included in parent company investment, net in the accompanying Combined Balance Sheets. Laidlaw Inc. Insurance premiums owed by the Company to Laidlaw, including those related to workers' compensation, general and auto liability, as described in Note 10, totaled $0.4 million, $0.4 million and $1.5 million at August 31, 2001, 2000 and 1999, respectively. Rates paid under insurance contracts were determined on a similar basis as those charged under similar contracts with third-party insurers. Pursuant to the Rollins Acquisition, Laidlaw and LTI, and indirect wholly-owned subsidiaries of Laidlaw, agreed to jointly and severally indemnify Safety-Kleen for certain obligations and liabilities. Also pursuant to the acquisition, Safety-Kleen agreed to jointly and severally indemnify Laidlaw and LTI for certain obligations and liabilities. Additionally, certain other guaranties have been entered into by Laidlaw on behalf of Safety-Kleen (see Notes 7 and 10). Certain former directors or officers of Safety-Kleen Corp. also served as directors or officers of Laidlaw during fiscal 2000 and 1999. As of August 31, 2001, no directors or officers of Safety-Kleen Corp. served as directors or officers of Laidlaw. Currently, there are substantial claims and counterclaims between Safety-Kleen, Laidlaw and its affiliates (see Note 10). Rollins Truck Leasing Corp. Until February 26, 2001, Mr. Tippie, a director of Safety-Kleen Corp., was Chairman of the Board, Chairman of the Executive Committee, President and CEO of Rollins Truck Leasing Corp. At August 31, 2001, 2000 and 1999, the Company owed Rollins Truck Leasing Corp. approximately $0.7 million, $0.9 million and $0.9 million, respectively, for truck rentals. Rollins Truck Leasing Corp. also purchased certain supplies from the Company. At August 31, 2001, 2000 and 1999, no amounts were owed to the Company. Matlack Systems, Inc. Mr. Tippie is a director and shareholder of Matlack Systems, Inc. Mr. Rollins, Jr., who is a member of Safety-Kleen Corp.'s Board of Directors, is Chairman of the Board and a shareholder of Matlack Systems, Inc. At August 31, 2001, 2000 and 1999, the Company owed Matlack Systems, Inc. approximately $0.2 million, $0.2 million and $0.4 million, respectively, for transportation services. At August 31, 2001, 2000 and 1999, Matlack Systems, Inc. owed the Company approximately less than $0.1 million, for the purchases of supplies and services. The above related party transactions which involve certain current or former directors or officers of the Company and Safety-Kleen were conducted on terms similar to those of third parties. 34

If upon the occurrence of any Liquidation Event, the assets and funds to be distributed among the holders of Preferred Shares shall be insufficient to permit the payment to such holders of the full aforesaid preferential amounts, then the entire assets and funds of the Corporation available for distribution shall be distributed pro rata among the holders of Preferred Shares in proportion to the number of shares of such stock owned by each such holder.

Upon the cure of the Non-Redemption Event as to all Preferred Shares, the term of office of the Series C Board Designee elected by the holders of Preferred Shares pursuant to such special voting right shall forthwith terminate. So long as the Non-Redemption Event shall continue, any vacancy in the office of the Series C Board Designee may be filled, and the Series C Board Designee may be removed with or without cause, by written consent of the holders of a majority of the then outstanding Preferred Shares. As long as the Non-Redemption Event shall continue, holders of any of the outstanding capital stock (other than the Preferred Shares) of the Corporation entitled to vote on the election of directors shall not be entitled to vote on the election or removal of the Series C Board Designee. The Corporation shall take such actions (corporate or otherwise) as are necessary to effectuate this Section 6(d)(iii). 7. Change of Control/Organic Change. (a) Offer to Purchase.

Corporation to repurchase the Preferred Shares as a result of a Change of Control or Organic Change. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Certificate of Vote, the Corporation shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligation under this Certificate of Vote by virtue thereof. (v) On the Payment Date, the Corporation shall (A) accept for payment the Preferred Shares validly tendered pursuant to the Offer, (B) pay to the holders of shares so accepted the purchase price therefor in immediately available funds and (C) cancel each surrendered certificate and retire the shares represented thereby and issue replacement certificates representing Preferred Shares not tendered.

The Corporation shall not issue any fraction of a share of Common Stock upon any conversion. All shares of Common Stock (including fractions thereof) issuable upon conversion of more than one Preferred Share by a holder thereof shall be aggregated for purposes of determining whether the conversion would result in the issuance of a fraction of a share of Common Stock. If, after the aforementioned aggregation, the issuance would result in the issuance of a fraction of a share of Common Stock, the Corporation shall round such fraction of a share of Common Stock up or down to the nearest whole share with one half shares being rounded up. (b) Conversion Rate. The number of shares of Common Stock issuable upon conversion of each Preferred Share pursuant to Section 8(a) shall be determined according to the following formula (the "Conversion Rate"): Conversion Amount Conversion Price (c) Mechanics of Conversion.

(ii) Corporation's Response. Upon receipt by the Corporation of copy of a Conversion Notice, the Corporation shall (A) as soon as practicable, but in any event within two (2) Business Days, send, via facsimile, a confirmation of receipt of such Conversion Notice to such holder and the Transfer Agent, which confirmation shall constitute an instruction to the Transfer Agent to process such Conversion Notice in accordance with the terms herein and (B) on or before the second (2/nd/) Business Day following the date of receipt by the 18

Corporation of such Conversion Notice (the "Share Delivery Date"), (1) issue and deliver to the address as specified in the Conversion Notice, a certificate, registered in the name of the holder or its designee, for the number of shares of Common Stock to which the holder shall be entitled, or (2) provided the Transfer Agent is participating in The Depository Trust Corporation ("DTC") Fast Automated Securities Transfer Program, upon the request of the holder, credit such aggregate number of shares of Common Stock to which the holder shall be entitled to the holder's or its designee's balance account with DTC through its Deposit Withdrawal Agent Commission system. If the number of Preferred Shares represented by the Preferred Stock Certificate(s) submitted for conversion is greater than the number of Preferred Shares being converted, then the Corporation shall, as soon as practicable and in no event later than five Business Days after receipt of the Preferred Stock Certificate(s) (the "Preferred Stock Delivery Date") and at its own expense, issue and deliver to the holder a new Preferred Stock Certificate representing the number of Preferred Shares not converted. (iii) Dispute Resolution. In the case of a dispute as to the determination of the Conversion Price or the arithmetic calculation of the Conversion Rate, the Corporation shall instruct the Transfer Agent to issue to the holder the number of shares of Common Stock that is not disputed and shall transmit an explanation of the disputed determinations or arithmetic calculations to the holder via facsimile within five (5) Business Days of receipt of such holder's Conversion Notice or other date of determination. If such holder and the Corporation are unable to agree upon the determination of the Conversion Price or arithmetic calculation of the Conversion Rate within five (5) Business Days of such disputed determination or arithmetic calculation being transmitted to the holder, then the Corporation shall within three (3) Business Days submit via facsimile (a) the disputed determination of the Conversion Price to an independent, reputable investment bank selected by the Corporation and approved by the holders of at least 51% of the Preferred Shares then outstanding or (b) the disputed arithmetic calculation of the Conversion Rate to an independent, outside accountant approved by the holders of at least 51% of the Preferred Shares then outstanding. The Corporation shall cause the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Corporation and the holders of the results no later than five (5) Business Days from the time it receives the disputed determinations or calculations. Such investment bank's or accountant's determination or calculation, as the case may be, shall be binding upon all parties absent manifest error. (iv) Record Holder. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of Preferred Shares shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Conversion Date. (v) Pro Rata Conversion. In the event the Corporation receives a Conversion Notice from more than one holder of Preferred Shares for the same Conversion Date and the Corporation can convert some, but not all, of such Preferred Shares by virtue of the limitations expressly set forth in Section 11 hereof, the Corporation shall convert from each holder of Preferred Shares electing to have Preferred Shares converted at such time a pro rata amount of such holder's Preferred Shares submitted for conversion based on the number of Preferred Shares submitted for conversion on such date by such holder relative to the number of Preferred Shares submitted for conversion on such date. 19

(vi) Book-Entry. Notwithstanding anything to the contrary set forth herein, upon conversion of Preferred Shares in accordance with the terms hereof, the holder thereof shall not be required to physically surrender the certificate representing the Preferred Shares to the Corporation unless the full or remaining number of Preferred Shares represented by the certificate are being converted. The holder and the Corporation shall maintain records showing the number of Preferred Shares so converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the holder and the Corporation, so as not to require physical surrender of the certificate representing the Preferred Shares upon each such conversion. In the event of any dispute or discrepancy, such records of the Corporation establishing the number of Preferred Shares to which the record holder is entitled shall be controlling and determinative in the absence of manifest error. Notwithstanding the foregoing, if Preferred Shares represented by a certificate are converted as aforesaid, the holder may not transfer the certificate representing the Preferred Shares unless the holder first physically surrenders the certificate representing the Preferred Shares to the Corporation, whereupon the Corporation will forthwith issue and deliver upon the order of the holder a new certificate of like tenor, registered as the holder may request, representing in the aggregate the remaining number of Preferred Shares represented by such certificate. The holder and any assignee, by acceptance of a certificate, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of any Preferred Shares, the number of Preferred Shares represented by such certificate may be less than the number of Preferred Shares stated on the face thereof. Each certificate for Preferred Shares shall bear the following legend: ANY TRANSFEREE OF THIS CERTIFICATE SHOULD CAREFULLY REVIEW THE TERMS OF THE COMPANY'S CERTIFICATE OF VOTE OF DIRECTORS ESTABLISHING A SERIES OF A CLASS OF STOCK RELATING TO THE PREFERRED SHARES REPRESENTED BY THIS CERTIFICATE, INCLUDING SECTION 8(c)(vi) THEREOF. THE NUMBER OF PREFERRED SHARES REPRESENTED BY THIS CERTIFICATE MAY BE LESS THAN THE NUMBER OF PREFERRED SHARES STATED ON THE FACE HEREOF PURSUANT TO SECTION 8(c)(vi) OF THE CERTIFICATE OF VOTE RELATING TO THE PREFERRED SHARES REPRESENTED BY THIS CERTIFICATE. (d) Taxes.

(e) Adjustments to Conversion Price. The Conversion Price shall be subject to adjustment from time to time as provided in this Section 8(e). (i) Adjustment of Conversion Price upon Issuance of Common Stock. If and whenever on or after the Issuance Date, the Corporation issues or sells, or in accordance with this Section 8(e) is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account 20

of the Corporation, but excluding shares of Common Stock: (a) issued or deemed to have been issued by the Corporation in connection with an Approved Stock Plan (not to exceed 2,500,000 shares of Common Stock as constituted on the date hereof and provided in each case that the exercise or purchase price for any such share shall not be less than 85% of the fair market value (determined in good faith by the Corporation's Board of Directors) of the Common Stock on the date of the grant); (b) deemed to have been issued upon issuance of the Preferred Shares or issued upon conversion of the Preferred Shares and (c) issued upon exercise of Options or Convertible Securities which are outstanding on the date immediately preceding the Issuance Date, provided that such issuance of shares of Common Stock upon exercise of such Options or Convertible Securities is made pursuant to the terms of such Options or Convertible Securities in effect on the date immediately preceding the Issuance Date and such Options or Convertible Securities are not amended after the date immediately preceding the Issuance Date), for a consideration per share less than a price (the "Applicable Price") equal to the higher of the Current Market Price and the Conversion Price, each as in effect immediately prior to such issuance, then immediately after such issue or sale, the Conversion Price then in effect shall be reduced to an amount equal to the product of (1) the Conversion Price in effect immediately prior to such issue or sale and (2) the quotient of (A) the sum of (x) the product of the Applicable Price and the number of shares of Common Stock Deemed Outstanding immediately prior to such issue or sale and (y) the consideration, if any, received by the Corporation upon such issue or sale, divided by (B) the product of (x) the Applicable Price multiplied by (y) the number of shares of Common Stock Deemed Outstanding immediately after such issue or sale. For purposes of determining the adjusted Conversion Price under this Section 8(e)(i), the following provisions shall be applicable: (A) Issuance of Options. If the Corporation in any manner grants or sells any Options and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exchange or exercise of any Convertible Securities issuable upon exercise of such Option is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Corporation at the time of the granting or sale of such Option for such price per share. For purposes of this Section 8(e)(i)(A), the "lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exchange or exercise of any Convertible Securities issuable upon exercise of such Option" shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Corporation with respect to any one share of Common Stock (disregarding, prior to its occurrence, any potential adjustment thereto described in Section 8(e)(i)(C) unless and until the same shall occur) upon granting or sale of the Option, upon exercise of the Option and upon conversion, exchange or exercise of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Conversion Price shall be made upon the actual issuance of such Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Stock upon conversion, exchange or exercise of such Convertible Securities. (B) Issuance of Convertible Securities. If the Corporation in any manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon such conversion, exchange or exercise thereof is less than the Applicable Price, then such share of Common Stock shall be 21

deemed to be outstanding and to have been issued and sold by the Corporation at the time of the issuance of sale of such Convertible Securities for such price per share. For the purposes of this Section 8(e)(i)(B), the "lowest price per share for which one share of Common Stock is issuable upon such conversion, exchange or exercise" shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Corporation with respect to any one share of Common Stock (disregarding, prior to its occurrence, any potential adjustment thereto described in Section 8(e)(i)(C) unless and until the same shall occur) upon the issuance or sale of the Convertible Security and upon the conversion, exchange or exercise of such Convertible Security. No further adjustment of the Conversion Price shall be made upon the actual issuance of such Common Stock upon conversion, exchange or exercise of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion Price had been or are to be made pursuant to other provisions of this Section 8(e)(i), no further adjustment of the Conversion Price shall be made by reason of such issue or sale. (C) Change in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exchange or exercise of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exchangeable or exercisable for Common Stock changes at any time, the Conversion Price in effect at the time of such change shall be adjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 8(e)(i)(C), if the terms of any Option or Convertible Security that was outstanding as of the date of issuance of the Preferred Shares are changed in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such change. Notwithstanding the foregoing, no adjustment shall be made if such adjustment would result in an increase of the Conversion Price then in effect. (D) Calculation of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Corporation, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a per Option or per unit, as applicable, consideration of $0.01. If any Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the gross amount received by the Corporation therefor. If any Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Corporation will be the fair value of such consideration, except where such consideration consists of marketable securities, in which case the amount of consideration received by the Corporation will be the arithmetic average of the Closing Sale Prices of such securities during the ten (10) consecutive trading days ending on the date of receipt of such securities. The fair value of any consideration other than cash or securities will be determined jointly by the Corporation and the holders of at least 51% of the Preferred Shares then outstanding. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event 22

requiring valuation (the "Valuation Event"), the fair value of such consideration will be determined within five Business Days after the tenth (10th) day following the Valuation Event by an independent, nationally recognized investment banking firm selected by the Corporation and the holders of at least 51% of the Preferred Shares then outstanding. The determination of such appraiser shall be deemed binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Corporation. (E) Record Date. If the Corporation takes a record of the holders of Common Stock for the purpose of entitling them (1) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (2) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. (ii) Adjustment of Conversion Price upon Subdivision or Combination of Common Stock. If the Corporation at any time subdivides (by any stock split, stock dividend, recapitalization or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. If the Corporation at any time combines (by combination, reverse stock split or otherwise) its outstanding shares of Common Stock into a smaller number of shares and the Conversion Price in effect immediately prior to such combination will be proportionately increased. (iii) Adjustment of Conversion Price on Adjustment Date. In addition to any other adjustment to the Conversion Price provided for in this Certificate of Vote, if (A) the Consolidated EBITDA of the Corporation (as such term is defined in the Financing Agreement), for the Fiscal Year ending December 31, 2003 is not greater than $115 million, as certified in writing by the chief financial officer of the Corporation to each holder of Preferred Shares as soon as is available, but not later than March 30, 2004 (the "2004 Consolidated EBITDA Certificate") and (B) the arithmetic average of the Closing Sale Prices of the Common Stock during the Adjustment Measuring Period is less than $27.50 (appropriately adjusted to reflect any stock dividend, stock split, stock combination or other similar transaction occurring from and after the Issuance Date), then the Conversion Price for the Preferred Shares shall be reduced effective as of the Adjustment Date to an amount equal to the Adjustment Price, subject to further adjustment as provided in this Certificate of Vote. If any holder of Preferred Shares disputes any calculation by the Corporation required by this Section 8(e)(iii), (including, without limitation, the Corporation's calculation of Consolidated EBITDA contained in the 2004 Consolidated EBITDA Certificate), such holder shall deliver to the Corporation (and the Corporation shall immediately thereafter deliver such notice to each other holder of Preferred Shares) within ten (10) Business Days of such holder's receipt of the 2004 Consolidated EBITDA Certificate a written notice of such dispute describing the basis for such dispute. If the Corporation and the disputing holder(s) of Preferred Shares cannot arrive at a compromise to such dispute within five (5) Business Days of the Corporation's receipt of written notice thereof from the disputing holder(s), then such dispute shall be resolved in accordance with the procedures set forth in Section 8(c)(iii) hereof. 23

(iv) If the Corporation, at any time while Preferred Shares are outstanding, shall distribute to all holders of Common Stock (and not to the holders of Preferred Shares) evidences of its indebtedness or assets or rights or warrants to subscribe for or purchase any security, then in each such case the Conversion Price at which each share of Preferred Stock shall thereafter be convertible shall be determined by multiplying the Conversion Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution by a fraction of which the denominator shall be the Closing Sale Price of a share of Common Stock determined as of the record date mentioned above, and of which the numerator shall be such Closing Sale Price on such record date less the then fair market value at such record date of the portion of such assets or evidence of indebtedness so distributed applicable to one outstanding share of Common Stock as determined by the Board in good faith. If any holder of Preferred Shares shall dispute the findings of the Corporation's Board, then such fair market value shall be determined in accordance by a nationally recognized investment banking firm selected by the Corporation and approved by the holders of not less than 51% of the then outstanding Preferred Shares in accordance with Section 8(c)(iii). In either case the adjustments shall be described in a statement provided to each holder of Preferred Shares of the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to one share of Common Stock. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above. (v) Other Events. If any event occurs of the type contemplated by the provisions of this Section 8(e) but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Corporation's Board of Directors will make an appropriate adjustment in the Conversion Price so as to protect the rights of the holders of the Preferred Shares; provided that no such adjustment will increase the Conversion Price as otherwise determined pursuant to this Section 8(e). (vi) Notices. (A) Whenever the Conversion Price is required to be adjusted as provided herein, the Corporation (1) shall immediately compute the Conversion Price, (2) shall prepare a certificate signed by the Corporation's Treasurer setting forth such Conversion Price and showing in detail the facts upon which such adjustment is based, which certificate shall be certified by the independent public accountants regularly employed by the Corporation (and corrected, if such accountants determine that the Corporation's certification is incorrect), and (3) shall mail a copy of such certificates to each holder of record of then outstanding Preferred Shares. A copy of such certificate shall also forthwith be filed with the Corporation's Transfer Agent. Until further adjusted, the Conversion Price shall be as set forth in such certificate. In the case of a dispute as to the determination of such adjustment between the Corporation and any holder of Preferred Shares, then such dispute shall be resolved in accordance with the procedures set forth in Section 8(c)(iii). (B) The Corporation will give written notice to each holder of Preferred Shares at least ten (10) Business Days prior to the date on which the Corporation closes its books or takes a record (1) with respect to any dividend or distribution 24

upon the Common Stock, (2) with respect to any pro rata subscription offer to holders of Common Stock or (3) for determining rights to vote with respect to any Organic Change. (C) The Corporation will also give written notice to each holder of Preferred Shares at least ten (10) Business Days prior to the date on which any Organic Change, dissolution or liquidation will take place. 9. Voting Rights; Board Observation Rights. (a) Voting Rights. Except as may be otherwise provided in this Certificate of Vote or required by law, the Preferred Shares shall vote together with all other classes and series of stock of the Corporation as a single class on all actions to be taken by the stockholders of the Corporation. Each Preferred Share shall have a number of votes, subject to reduction pursuant to Section 11 hereof, equal to the quotient determined by dividing (a) the number of shares of Common Stock into which all of the outstanding Preferred Shares are then convertible in accordance with Section 8 (but subject to the limitation in Section 11) divided by (b) the number of Preferred Shares then outstanding. Each holder of Preferred Shares shall be entitled to notice of any stockholders' meeting in accordance with the By-Laws of the Corporation. (b) Board Observation Rights. For so long as Oak Hill Advisors, Inc. ("Oak Hill") and its Affiliates and funds and accounts that Oak Hill and its Affiliates control or advise own in the aggregate not less than 2,500 Preferred Shares (subject to adjustment for any stock split, subdivision, combination or other similar transaction), Oak Hill shall be entitled to appoint one (1) designee who shall be entitled to observe the meetings of the Board of Director of the Corporation in a non-voting capacity. Such observer shall have full rights to attend all meetings of the Board of Directors of the Corporation and all meetings (whether such meetings are formal or informal, are convened in person, telephonically, or via any other telecommunication means) of any committee or subcommittee of the Board of Directors of the Corporation, including, without limitation, any executive, compensation, governance, nominating and audit committee. In connection with the rights set forth in this Section 9(b), the Corporation shall (i) provide all materials distributed to the members of the Board of Directors of the Company (and any committee or subcommittee thereof) to each Person designated by Oak Hill hereunder at the same time such materials are distributed to other Board, committee or subcommittee members and (ii) pay all reasonable expenses of such Person to attend the meetings of the Board of Directors (and any committee or subcommittee thereof). 10. Protective Provisions. The Corporation shall not, directly or indirectly, without the affirmative vote or written consent of the holders of not less than 51% of the then outstanding Preferred Shares, voting or consenting as a separate class: (a) enter into, renew, extend or be a party to, or permit any of its Subsidiaries to enter into, renew, extend or be a party to, any transaction or series of related transactions (including, without limitation, the purchase, sale, lease, transfer or exchange of property or assets of any kind or the rendering of services of any kind) with any Affiliate, except (1) in the ordinary course of business in a manner and to an extent consistent with past practice and necessary or desirable for the prudent operation of its business, for fair consideration and on 25

terms no less favorable to it or its Subsidiaries than would be obtainable in a comparable arm's length transaction with a Person that is not an Affiliate thereof, (2) transactions with another wholly-owned Subsidiary of the Corporation or the Corporation and (3) transactions permitted by Section 10(f) hereof; (b) (1) declare or pay any dividend or other distribution, direct or indirect, on account of any Capital Stock of the Corporation or any of its Subsidiaries, now or hereafter outstanding, (2) make any repurchase, redemption, retirement, defeasance, sinking fund or similar payment, purchase or other acquisition for value, direct or indirect, of any Capital Stock of any of the Corporation or any of its Subsidiaries, now or hereafter outstanding, (3) make any payment to retire, or to obtain the surrender of, any outstanding warrants, options or other rights for the purchase or acquisition of shares of any class of Capital Stock of any of the Corporation or any of its Subsidiaries, now or hereafter outstanding, (4) return any Capital Stock to any shareholders or other equity holders of any of the Corporation or any of its Subsidiaries, or make any other distribution of property, assets, shares of Capital Stock, warrants, rights, options, obligations or securities thereto as such or (5) pay any management fees or any other fees or expenses (including the reimbursement thereof by any of the Corporation or any of its Subsidiaries) pursuant to any management, consulting or other services agreement to any of the shareholders or other equity holders of any of the Corporation or any of its Subsidiaries or other Affiliates, or to any other Subsidiaries or Affiliates of the Corporation; provided, however, (A) any Subsidiary of the Corporation may pay dividends to the Corporation or another Subsidiary of the Corporation (B) the Corporation may pay dividends on its outstanding common Capital Stock in the form of common Capital Stock, provided that an adjustment for such payment is provided for in Section 8(e) hereof, (C) the Corporation may pay cash dividends in the annual amount of $4.00 per share per twelve-month period upon each of the 112,000 shares of the Corporation's Series B Preferred Stock which are currently outstanding, and (D) the Corporation may accrue Dividends and make Cash Dividend Payments to the holders of Preferred Shares in the manner provided in Section 4 hereof provided that, in each case of clauses (A) through (D) above, no payment shall be made if Section 7.02(h) of the Financing Agreement would prohibit such payment; (c) create, incur, assume, guarantee or suffer to exist, or otherwise become or remain liable with respect to, or permit any of its Subsidiaries to create, incur, assume, guarantee or suffer to exist or otherwise become or remain liable with respect to, any Indebtedness other than Permitted Indebtedness; (d) create, incur, assume or suffer to exist, or permit any of its Subsidiaries to create, incur, assume or suffer to exist, any Lien upon or with respect to any of its properties, whether now owned or hereafter acquired; file or suffer to exist under the Uniform Commercial Code or any similar law or statute of any jurisdiction, a financing statement (or the equivalent thereof) that names it or any of its Subsidiaries as debtor; sign or suffer to exist any security agreement authorizing any secured party thereunder to file such financing statement (or the equivalent thereof); sell any of its property or assets subject to an understanding or agreement, contingent or otherwise, to repurchase such property or assets (including sales of accounts receivable) with recourse to it or any of its Subsidiaries or assign or otherwise transfer, or permit any of its Subsidiaries to assign or otherwise transfer, any account or other right to receive income; other than, as to all of the above, Permitted Liens; 26

(e) Wind-up, liquidate or dissolve, or merge, consolidate or amalgamate with any Person, or convey, sell, lease or sublease, transfer or otherwise dispose of, whether in one transaction or a series of related transactions, all or any part of its business, property or assets, whether now owned or hereafter acquired (or agree to do any of the foregoing), or purchase or otherwise acquire, whether in one transaction or a series of related transactions, all or substantially all of the assets of any Person (or any division thereof) (or agree to do any of the foregoing), or permit any of its Subsidiaries to do any of the foregoing; provided, however, that (i) any direct or indirect wholly-owned Subsidiary of the Corporation may be merged into any other direct or indirect wholly-owned Subsidiary of the Corporation, or may consolidate with another direct or indirect wholly-owned Subsidiary of the Corporation, so long as no other provision of this Certificate of Vote would be violated thereby; and (ii) any of the Corporation and its Subsidiaries may (A) sell Inventory in the ordinary course of business, (B) dispose of obsolete or worn-out equipment in the ordinary course of business, (C) sell or otherwise dispose of other property or assets (other than any Capital Stock, Rolling Stock or any Facility of any of the Corporation or any of its Subsidiaries) for cash in an aggregate amount not less than the fair market value of such property or assets, and (D) sell or otherwise dispose of Rolling Stock for cash in an amount not less than the fair market value of such Rolling Stock, provided that the net cash proceeds of such dispositions in the case of clauses (B), (C) and (D) above, do not exceed $500,000 in the aggregate in any twelve-month period and the conditions of Section 7.02(c)(ii) of the Financing Agreement are satisfied. (f) Make or commit or agree to make any loan, advance, guarantee of obligations, other extension of credit or capital contributions to, or hold or invest in or commit or agree to hold or invest in, or purchase or otherwise acquire or commit or agree to purchase or otherwise acquire any shares of the Capital Stock, bonds, notes, debentures or other securities of, or make or commit or agree to make any other investment in, any other Person, or purchase or own any futures contract or otherwise become liable for the purchase or sale of currency or other commodities at a future date in the nature of a futures contract, or permit any of its Subsidiaries to do any of the foregoing, except for: (i) investments existing on the Issuance Date, as set forth on Schedule 7.02(e) to the Financing Agreement, but not any increase in the amount thereof as set forth in such Schedule or any other modification of the terms thereof, (ii) investments made by the Company or any Subsidiary of the Company that is a Loan Party (as defined in the Financing Agreement) in or to its respective wholly-owned Subsidiaries and by such Subsidiaries to it, made in the ordinary course of business, provided that the aggregate principal amount of such investments made in or to the Loan Parties' Subsidiaries organized outside of the United States (exclusive of (A) investments in the Capital Stock of such Subsidiaries resulting from the allocation of the consideration paid by the Loan Parties for the CSD Acquisition Assets (as defined in the Financing Agreement) and (B) Indebtedness incurred by a Loan Party on behalf of one or more of its Subsidiaries which is permitted under clause (i) of the definition of "Permitted Indebtedness") shall not exceed, in the case of such Subsidiaries organized under the laws of a Canadian province, $5,000,000 or, in the case of any other Subsidiary organized outside the 27

United States, $500,000, in each case at any one time outstanding, and (iii) Permitted Investments; (g) Make or commit or agree to make, or permit any of its Subsidiaries to make or commit or agree to make, any Capital Expenditure (by purchase or Capitalized Lease) that would cause the aggregate amount of all Capital Expenditures made by the Corporation and their Subsidiaries to exceed the amount permitted in any Fiscal Year under Section 7.02(g) of the Financing Agreement; (h) Create or otherwise cause, incur, assume, suffer or permit to exist or become effective any consensual encumbrance or restriction of any kind on the ability of any direct or indirect Subsidiary of the Corporation (i) to pay dividends or to make any other distribution on any shares of Capital Stock of such Subsidiary owned by directly or indirectly by the Corporation, (ii) to pay or prepay or to subordinate any Indebtedness owed to any of the Corporation or any of its Subsidiaries, (iii) to make loans or advances to any of the Corporation or any of its Subsidiaries or (iv) to transfer any of its property or assets to any of the Corporation or any of its Subsidiaries, or permit any of its Subsidiaries to do any of the foregoing; provided, however, that nothing in any of clauses (i) through (iv) of this Section 10(h) shall prohibit or restrict compliance with: (A) the Financing Agreement, the Revolving Credit Agreement, or any other agreement or instrument entered into in connection therewith; (B) any agreements in effect on the Issuance Date and described on Schedule 7.02(k) to the Financing Agreement; (C) any applicable law, rule or regulation (including, without limitation, applicable currency control laws and applicable state corporate statutes restricting the payment of dividends in certain circumstances); (D) in the case of clause (iv) any agreement setting forth customary restrictions on the subletting, assignment or transfer of any property or asset that is a lease, license, conveyance or contract of similar property or assets; or (E) in the case of clause (iv) any agreement, instrument or other document evidencing a Permitted Lien from restricting on customary terms the transfer of any property or assets subject thereto. (i) assume, or accept any assignment of, directly or indirectly, after the Issuance Date any contract, agreement or obligation of Safety-Kleen Corp. or its Affiliates or Subsidiaries containing or otherwise imposing on the Corporation or any of its Affiliates or Subsidiaries any material indemnification or guarantee obligation, other than those contracts and agreements listed in a schedule delivered prior to the Effective Date to each holder of Preferred Shares as of the Effective Date; (j) amend, alter, change, repeal or waive any provision of its Articles of Organization (whether by way of a Certificate of Vote or otherwise) or this Certificate of Vote 28

or its By-laws in any manner (whether by merger, consolidation or otherwise), that would adversely affect the rights, preferences or privileges of the Preferred Shares; (k) create or authorize the creation of or issue (including, without limitation, by way of recapitalization), or obligate itself or any Subsidiary to authorize or issue any shares of any series of preferred stock of the Corporation or any such Subsidiary, or any other security exercisable for or convertible into any shares of any series of preferred stock of the Corporation or any Subsidiary, whether any such creation or authorization shall be by means of amendment of the Articles of Organization (whether by way of a Certificate of Vote or otherwise) or of this Certificate of Vote or by merger, consolidation or otherwise; (l) issue or authorize the issuance of any Preferred Shares after the Issuance Date; (m) issue or authorize the issuance of any shares of Series B Preferred Stock of the Corporation after the Issuance Date; (n) modify or amend the terms of the Series B Preferred Stock in a manner that could reasonably be expected to adversely affect the rights of the holders of Preferred Shares; or (o) enter into any contract, agreement, commitment or understanding with respect to any of the foregoing. If the Company shall have breached or defaulted with respect to any of the covenants set forth in this Section 10, and such breach has not been cured, if curable, within 30 days of written notice to the Company thereof (each, a "Covenant Default"), then, immediately upon the occurrence of such Covenant Default, (i) the Dividend Rate in effect on the date of the Covenant Default shall increase by six percent (6%) until the later of (A) the six-month anniversary of the date of the occurrence of the Covenant Default and (B) the date on which such Covenant Default is cured and (ii) the Conversion Price shall automatically be adjusted (subject to further adjustment pursuant to this Certificate of Vote subsequent to such adjustment) to an amount equal to (A) the Adjustment Price, in the event the Conversion Price in effect on the date of the Covenant Default is greater than the Adjustment Price and (B) the product of (I) 0.9 and (II) the Conversion Price in effect on the date of the Covenant Default, in the event the Conversion Price in effect on the date of the Covenant Default is less than or equal to the Adjustment Price. 11. Limitation on Number of Conversion Shares. Notwithstanding anything to the contrary contained herein, (a) the Corporation shall not be obligated to issue any shares of Common Stock upon conversion of the Preferred Shares if the issuance of such shares of Common Stock would exceed that number of shares of Common Stock which the Corporation may issue upon conversion of the Preferred Shares without breaching the Corporation's obligations under the rules or regulations of the Principal Market, or the market or exchange where the Common Stock is then traded (the "Exchange Cap") and (b) the holders of Preferred Shares may not exercise voting power with respect to any Preferred Shares in accordance with Section 9 hereof on any matter brought before all holders of Capital Stock of the Corporation to 29

the extent that voting such Preferred Shares shall cause the Corporation to breach its obligations under the Exchange Cap, except that such limitations shall not apply in the event that the Corporation (i) obtains the approval of its stockholders as required by the applicable rules of the Principal Market (or any successor rule or regulation) for issuances of Common Stock in excess of such amount, or (ii) obtains a written opinion from outside counsel to the Corporation that such approval is not required, which opinion shall be reasonably satisfactory to the holders of at least 51% of the Preferred Shares then outstanding. Until such approval or written opinion is obtained, (A) no purchaser of Preferred Shares pursuant to the Purchase Agreement (the "Purchasers") shall be issued, upon conversion of Preferred Shares, shares of Common Stock and (B) no Purchaser shall have the right to exercise voting rights on matters brought before all holders of Capital Stock in accordance with Section 9 hereof in respect of Preferred Shares in an amount greater than the product of (1) the Exchange Cap amount multiplied by (2) a fraction, the numerator of which is the number of Preferred Shares issued to such Purchaser pursuant to the Purchase Agreement and the denominator of which is the aggregate amount of all the Preferred Shares issued to the Purchasers pursuant to the Purchase Agreement (the "Cap Allocation Amount"). In the event that any Purchaser shall sell or otherwise transfer any of such Purchaser's Preferred Shares, the transferee shall be allocated a pro rata portion of such Purchaser's Cap Allocation Amount. In the event that any holder of Preferred Shares shall convert all of such holder's Preferred Shares into a number of shares of Common Stock which, in the aggregate, is less than such holder's Cap Allocation Amount, then the difference between such holder's Cap Allocation Amount and the number of shares of Common Stock actually issued to such holder shall be allocated to the respective Cap Allocation Amounts of the remaining holders of Preferred Shares on a pro rata basis in proportion to the number of Preferred Shares then held by each such holder. If at any time when a holder of Preferred Shares shall deliver a Conversion Notice pursuant to Section 8(c) hereof the Corporation shall be prohibited pursuant to the provisions of this Section 11 from issuing all or any portion of the Conversion Shares issuable pursuant to such Conversion Notice, then the Corporation shall pay in immediately available funds to the holder within two (2) Business Days of the date of delivery of such Conversion Notice, an amount in cash equal to the product of (x) the number of shares of Common Stock which could not be issued by virtue of the limitations contained in this Section 11 multiplied by (y) the average of the Closing Sale Prices of the Common Stock on each of the five (5) trading days immediately preceding the date of delivery of such Conversion Notice, and concurrent with, and subject to such payment by the Corporation, the number of Preferred Shares held by such holder shall be reduced on the books and records of the Corporation in accordance with Section 8(c)(vi) by the number of Preferred Shares that were subject to the Conversion Notice and could not be converted by virtue of the limitations of this Section 11. 12. Lost or Stolen Certificates. Upon receipt by the Corporation of evidence reasonably satisfactory to the Corporation of the loss, theft, destruction or mutilation of any Preferred Stock Certificates representing the Preferred Shares, and, in the case of loss, theft or destruction, of an indemnification undertaking by the holder to the Corporation in customary form and, in the case of mutilation, upon surrender and cancellation of the Preferred Stock Certificate(s), the Corporation shall execute and deliver to the holder new preferred stock certificate(s) of like tenor and date. 13. Reservation of Shares. The Corporation shall, so long as any of the Preferred Shares are outstanding, take all action necessary to reserve and keep available out of its 30

authorized and unissued Common Stock, solely for the purpose of effecting the conversions of the Preferred Shares, such number of shares of Common Stock as shall from time to time be sufficient to effect the conversion of all of the Preferred Shares then outstanding (without regard to any limitations on conversions) under the terms of this Certificate of Vote as then in effect. The initial number of shares of Common Stock reserved for conversions of the Preferred Shares and each increase in the number of shares so reserved shall be allocated pro rata among the holders of the Preferred Shares based on the number of Preferred Shares held by each holder at the time of issuance of the Preferred Shares or increase in the number of reserved shares, as the case may be. In the event a holder shall sell or otherwise transfer any of such holder's Preferred Shares, each transferee shall be allocated a pro rata portion of the number of reserved shares of Common Stock reserved for such transferor. Any shares of Common Stock reserved and allocated to any Person which ceases to hold any Preferred Shares shall be allocated to the remaining holders of Preferred Shares, pro rata based on the number of Preferred Shares then held by such holders. 14. No Impairment. The Corporation shall not, by amendment of its Articles of Organization or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of the Preferred Shares set forth herein, but will at all times in good faith assist in the carrying out of all terms and in the taking of all action that may be necessary or appropriate in order to protect the rights of the holders of then outstanding Preferred Shares against dilution or other impairment. Without limiting the generality of the foregoing, the Corporation (a) shall not increase the par value of any shares of stock receivable on the conversion of Preferred Shares above the amount payable therefor on such conversion and (b) shall take all action that may be necessary or appropriate in order that the Corporation may validly and legally issue fully paid and nonassessable shares of stock on the conversion of all Preferred Shares from time to time outstanding. 15. Severability of Provisions. Whenever possible, each provision of this Certificate of Vote shall be interpreted in a manner as to be effective and valid under applicable law, but if any provision hereof is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating or otherwise adversely affecting the remaining provisions hereof. If a court of competent jurisdiction should determine that a provision hereof would be valid or enforceable if a period of time were extended or shortened or a particular percentage were increased or decreased, then such court may make such change as shall be necessary to render the provision in question effective and valid under applicable law. 16. Amendment, Waiver or Discharge. Except as otherwise expressly provided herein, neither this Certificate of Vote nor any term hereof may be amended, waived, modified, discharged or terminated without the written consent or affirmative vote of the holders of not less than 51% of the Preferred Shares then outstanding; provided, however, that no amendment, waiver or consent shall (a) change or extend the Mandatory Redemption Date, the Redemption Price or the Conversion Price applicable to any Preferred Shares, in each case without the written consent of the holder of such Preferred Shares (b) amend, modify or waive the conversion or redemption rights of any holder of Preferred Shares without the written consent 31

of such holder or (c) amend, modify or waive this Section 16 without the written consent of each holder of Preferred shares. 17. Remedies, Characterizations, Other Obligations, Breaches and Injunctive Relief. The remedies provided in this Certificate of Votes shall be cumulative and in addition to all other remedies available under this Certificate of Vote, at law or in equity (including a decree of specific performance and/or other injunctive relief). No remedy contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy. Nothing herein shall limit a holder's right to pursue actual damages for any failure by the Corporation to comply with the terms of this Certificate of Vote. The Corporation covenants to each holder of Preferred Shares that there shall be no characterization concerning this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, conversion and the like (and the computation thereof) shall be the amounts to be received by the holder thereof and shall not, except as expressly provided herein, be subject to any other obligation of the Corporation (or the performance thereof). The Corporation acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the holders of the Preferred Shares and that the remedy at law for any such breach may be inadequate. The Corporation therefore agrees that, in the event of any such breach or threatened breach, the holders of the Preferred Shares shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. 18. Failure or Indulgence Not Waiver. No failure or delay on the part of a holder of Preferred Shares in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege. 19. Notice. Whenever notice is required to be given under this Certificate of Vote, unless otherwise provided herein, such notice shall be given in accordance with Section 8 of the Purchase Agreement (provided that if the Preferred Shares are not held by a Buyer (as defined in the Purchase Agreement) then such notice shall be given to the holder of Preferred Shares at the address set forth on the books and records of the Corporation. 20. Transfer of Preferred Shares. A holder of Preferred Shares may assign some or all of the Preferred Shares and the accompanying rights hereunder held by such holder without the consent of the Corporation; provided that such assignment is in compliance with applicable securities laws and notice of such assignment is delivered to the Corporation promptly thereafter. 21. Preferred Share Register.

Each Borrower hereby releases and holds Agent and each Lender harmless from and against any acts, waivers, errors, delays or omissions, whether caused by any Borrower, by any issuer or correspondent or otherwise with respect to or relating to any Letter of Credit Accommodation, except for the gross negligence or willful misconduct of Agent or Canadian Lender, as applicable, as determined pursuant to a final, non-appealable order of a court of competent jurisdiction. The provisions of this Section 2.4 shall survive the payment of Obligations and the termination or non-renewal of this Agreement. (h) Each Borrower hereby irrevocably authorizes and directs any issuer of a Letter of Credit Accommodation to name Borrowers as the account party therein and to deliver to Agent or Canadian Lender, as applicable, all instruments, documents and other writings and property received by issuer pursuant to the Letter of Credit Accommodations and to accept and rely upon Agent's or Canadian Lender, as applicable, instructions and agreements with respect to all matters arising in connection with the Letter of Credit Accommodations or the applications therefor. Nothing contained herein shall be deemed or construed to grant any Borrower any right or authority to pledge the credit of Agent or any Lender in any manner. Neither Agent or Canadian Lender, as applicable, shall have any liability of any kind with respect to any Letter of Credit Accommodation provided by an issuer other than Agent or Canadian Lender unless Agent or Canadian Lender, as applicable, has duly executed and delivered to such issuer the application or a guarantee or indemnification in writing with respect to such Letter of Credit Accommodation. Borrowers shall be bound by any interpretation made in good faith by Agent or Canadian Lender, as applicable, or any other issuer or correspondent under or in connection with any Letter of Credit Accommodation or any documents, drafts or acceptances thereunder, notwithstanding that such interpretation may be inconsistent with any instructions of Borrowers. Agent and Canadian Lender shall have the sole and exclusive right and authority to, and Borrowers shall not: (i) at any time an Event of Default exists or has occurred and is continuing, (A) approve or resolve any questions of non-compliance of documents, (B) give any instructions as to acceptance or rejection of any documents or goods, or (C) execute any and all applications for steamship or airway guaranties, indemnities or delivery orders; and (ii) at all times, (A) grant 29

any extensions of the maturity of, time of payment for, or time of presentation of, any drafts, acceptances, or documents, and (B) agree to any amendments, renewals, extensions, modifications, changes or cancellations of any of the terms or conditions of any of the applications, Letter of Credit Accommodations, or documents, drafts or acceptances thereunder or any letters of credit included in the Collateral. Agent or Canadian Lender, as applicable, may take such actions either in its own name or in any Borrower's name. (i) Any rights, remedies, duties or obligations granted or undertaken by Borrowers to any issuer or correspondent in any application for any Letter of Credit Accommodation, or any other agreement in favor of any issuer or correspondent relating to any Letter of Credit Accommodation, shall be deemed to have been granted or undertaken by Borrowers to Agent or Canadian Lender, as applicable. Any duties or obligations undertaken by Agent or Canadian Lender to any issuer or correspondent in any application for any Letter of Credit Accommodation, or any other agreement by Agent or Canadian Lender in favor of any issuer or correspondent relating to any Letter of Credit Accommodation, shall be deemed to have been undertaken by Borrowers to Agent or Canadian Lender, as applicable, and to apply in all respects to Borrowers. (j) To induce Agent to issue or cause to be issued Letter of Credit Accommodations, each Lender (an "LC Participant") under the Canadian Credit Facility or US Credit Facility, as applicable, irrevocably agrees to accept and purchase and hereby accepts and purchases, on the terms and conditions hereinafter stated, for such LC Participant's own account and risk, an undivided interest and participation equal to such LC Participant's Pro Rata Share in the Agent's or Canadian Lender's obligations and rights under each Letter of Credit Accommodation. Each LC Participant unconditionally and irrevocably agrees with the Agent or Canadian Lender, that it shall be directly and unconditionally obligated to the Agent or Canadian Lender to reimburse the Agent or Canadian Lender upon demand and without setoff or deduction of any kind or nature, for making any payment under any Letter of Credit Accommodation, in an amount equal to such LC Participant's Pro Rata Share multiplied by the amount of such payment made by the Agent or Canadian Lender, as applicable, under such Letter of Credit Accommodation. If any amount required to be paid by any LC Participant to the Agent pursuant hereto in respect of any payment made by the Agent or Canadian Lender under any Letter of Credit Accommodation is not paid to Agent or Canadian Lender on the date such payment is due from such LC Participant, such LC Participant shall pay to the Agent or Canadian Lender, as applicable, on demand an amount equal to the product of (i) such amount, times (ii) (A) the Federal Funds Rate during the period from and including the date such payment is required to and including the third day after such payment is required and (B) thereafter, the Interest Rate applicable to Prime Rate Loans to the date on which such payment is immediately available to the Agent or Canadian Lender, as applicable, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360 in the case of US Letters of Credit and the denominator of which is 365 in the case of Canadian Letters of Credit. A certificate of the Agent or Canadian Lender, as applicable, submitted to any LC Participant with respect to any amounts owing under this subsection shall be conclusive in the absence of manifest error. Whenever, at any time after the Agent or Canadian Lender, as applicable, has made payment under any Letter of Credit Accommodation and has received from any LC Participant its pro rata share of such payment in accordance herewith, and the Agent or Canadian Lender, as applicable, receives any payment from the Borrowers on account of such payment under such Letter of Credit Accommodation (whether directly from the Borrowers or 30

otherwise, including by way of set-off or proceeds of collateral applied thereto by the Agent or Canadian Lender, as applicable), or any payment of interest on account thereof, the Agent shall distribute to such LC Participant its pro rata share thereof; provided, however, that in the event that any such payment received by the Agent or Canadian Lender shall be required to be returned by the Agent or Canadian Lender, such LC Participant shall return to the Agent the portion thereof previously distributed by the Agent to it. The obligations of each LC Participant to make payments to the Agent with respect to its participation in any Letter of Credit Accommodation shall be absolute and unconditional under any and all circumstances and irrespective of any set-off, counterclaim or defense to payment which any Lender or any Borrower may have or have had against the Agent, the issuing bank or any beneficiary of a Letter of Credit Accommodation. 2.5 Borrower Representative. Each Borrower hereby irrevocably designates the Parent as its representative and agent on its behalf (the "Borrower Representative") for the purpose of requesting on such Borrower's behalf borrowings of US Revolving Loans or Canadian Revolving Loans, as applicable, and the continuation and/or conversion of US Revolving Loans or Canadian Revolving Loans, as applicable, giving instructions with respect to the disbursement of the proceeds of US Revolving Loans or Canadian Revolving Loans, as applicable, to be made to US Borrowers or Canadian Borrowers, as applicable, selecting interest rate options for US Borrowers or Canadian Borrowers, as applicable, requesting US Letter of Credit or Canadian Letter of Credit Accommodations, as applicable, for the account of US Borrowers or Canadian Borrowers, as applicable, giving and receiving on Borrowers' behalf all other notices and consents hereunder or under any of the other Financing Agreements and taking all other actions (including in respect of compliance with covenants) on behalf of Borrowers under the Financing Agreements. The Borrower Representative hereby accepts such appointment. The Agent and each Lender may regard any notice or other communication pursuant to any Financing Agreement from the Borrower Representative as a notice or communication from the US Borrowers or Canadian Borrowers, as applicable, and may give any notice or communication required or permitted to be given to any Borrower or Borrowers hereunder to the Borrower Representative on behalf of such Borrower or Borrowers. Each Borrower agrees that each notice, election, representation and warranty, covenant, agreement and undertaking made on its behalf by the Borrower Representative shall be deemed for all purposes to have been made by such Borrower and shall be binding upon and enforceable against such Borrower to the same extent as if the same had been made directly by such Borrower. This appointment of Parent as Borrower Representative may not be terminated, rescinded or changed without the prior written consent of Agent, provided that upon Agent's request, the Borrowers shall designate an alternative Borrower Representative satisfactory to Agent. 2.6 Syndication. Borrowers agree to actively assist Agent in completing the syndication of the Obligations in a manner satisfactory to Agent. In connection with such syndication, Borrowers shall: (a) promptly prepare financial information and projections including balance sheets and income, cash flow and availability projections for dissemination to prospective Lenders as Agent may request and in form and substance satisfactory to Agent, (b) make available senior management and advisors of the Borrowers to meet with prospective Lenders as Agent may request, and (c) assist Agent and its representatives in the preparation of other information and materials to be used in connection with the syndication. Borrowers agree that Agent will exclusively manage all aspects of the syndication including decisions as to the selection and timing of financial institutions to be approached, which financing institutions will be selected to be Lenders and the allocation of Pro Rata Shares and compensation to Lenders. 31

Borrowers further agree, upon Agent's request, to enter into such amendments and modifications to this Agreement and to the other Financing Agreement as Agent may request in connection with such syndication and to respond to requests made by prospective Lenders. SECTION 3. INTEREST AND FEES. 3.1 Interest. (a) US Borrowers shall pay to Agent for the ratable benefit of US Lenders and Canadian Borrowers shall pay to Agent for the benefit of Canadian Lender interest on the outstanding principal amount of the Loans at the applicable Interest Rate. All interest accruing hereunder on and after the date of any Event of Default or termination hereof shall be payable on demand. (b) Borrower Representative may from time to time request Eurodollar Rate Loans or may request that Prime Rate Loans be converted to Eurodollar Rate Loans or that any existing Eurodollar Rate Loans continue for an additional Interest Period. Such request from Borrower Representative shall be in writing on such form or forms as Agent may require and shall specify, without limitation, the amount of the Eurodollar Rate Loans or the amount of the Prime Rate Loans to be converted to Eurodollar Rate Loans or the amount of the Eurodollar Rate Loans to be continued (subject to the limits set forth below) and the Interest Period to be applicable to such Eurodollar Rate Loans. Subject to the terms and conditions contained herein, three (3) Business Days after receipt by Agent of such a request from Borrower Representative, such Prime Rate Loans shall be converted to Eurodollar Rate Loans or such Eurodollar Rate Loans shall continue, as the case may be, provided, that, (i) no Default or Event of Default shall exist or have occurred and be continuing, (ii) no party hereto shall have sent any notice of termination or non-renewal of this Agreement, (iii) Borrowers shall have complied with such customary procedures as are established by Agent and specified by Agent to Borrowers from time to time for requests by Borrowers for Eurodollar Rate Loans, (iv) no more than four (4) Interest Periods may be in effect at any one time, (v) the aggregate amount of the Eurodollar Rate Loans must be in an amount not less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof, (vi) the maximum amount of the Eurodollar Rate Loans at any time requested by Borrowers shall not exceed the amount equal to eighty (80%) percent of the lowest principal amount of the Revolving Loans which it is anticipated will be outstanding during the applicable Interest Period, in each case as determined by Agent (but with no obligation of Lenders to make such Loans), and (vii) Agent shall have determined that the Interest Period or Adjusted Eurodollar Rate is available to Lenders and Reference Bank and can be readily determined as of the date of the request for such Eurodollar Rate Loan by Borrowers. Any request by Borrower Representative for Eurodollar Rate Loans or to convert Prime Rate Loans to Eurodollar Rate Loans or to continue any existing Eurodollar Rate Loans shall be irrevocable. Notwithstanding anything to the contrary contained herein, Lenders and Reference Bank shall not be required to purchase United States Dollar deposits in the London interbank market or other applicable Eurodollar Rate market to fund any Eurodollar Rate Loans, but the provisions hereof shall be deemed to apply as if Lenders and Reference Bank had purchased such deposits to fund the Eurodollar Rate Loans. (c) Any Eurodollar Rate Loans shall automatically convert to US Prime Rate Loans upon the last day of the applicable Interest Period, unless Agent has received and 32

approved a request to continue such Eurodollar Rate Loans at least three (3) Business Days prior to such last day in accordance with the terms hereof. Any Eurodollar Rate Loans shall, at Agent's option, upon notice by Agent to Borrowers, convert to US Prime Rate Loans in the case of US Dollar Loans in the event that this Agreement shall terminate or not be renewed. US Borrowers shall pay to Agent for the benefit of US Lenders, and Canadian Borrowers shall pay to Agent for the benefit of Canadian Lender, in each case upon demand by any Lender (or Agent or any such Lender may, at its option, charge any loan account of Borrower) any amounts required to compensate such Lender, the Reference Bank or any participant with any such Lender for any loss (including loss of anticipated profits), cost or expense incurred by such person, as a result of the conversion of Eurodollar Rate Loans to Prime Rate Loans pursuant to any of the foregoing. (d) Interest shall be payable by US Borrowers to Agent for the account of US Lenders and by Canadian Borrowers to Agent for the account of Canadian Lender, monthly in arrears not later than the first day of each calendar month and shall be calculated on the basis of (i) a three hundred sixty-five (365) day year in the case of Canadian Dollar Loans and (ii) a three hundred sixty (360) day year in the case of US Dollar Loans and in each case based on actual days elapsed. The interest rate on non-contingent Obligations (other than Eurodollar Rate Loans) shall increase or decrease by an amount equal to each increase or decrease in the Prime Rate effective on the first day of the month after any change in such Prime Rate is announced based on the Prime Rate in effect on the last day of the month in which any such change occurs. In no event shall charges constituting interest payable by Borrowers to Agent or to Lenders exceed the maximum amount or the rate permitted under any applicable law or regulation, and if any such part or provision of this Agreement is in contravention of any such law or regulation, such part or provision shall be deemed amended to conform thereto. (e) For purposes of disclosure under the Interest Act (Canada), where interest is calculated pursuant thereto at a rate based upon a three hundred sixty (360) day year or three hundred sixty-five (365) day year (the "First Rate"), the rate or percentage of interest on a yearly basis is equivalent to such First Rate multiplied by the actual number of days in the year divided by three hundred sixty (360) or three hundred sixty-five (365), as applicable. (f) Notwithstanding the provisions of this Section 3 or any other provision of this Agreement, in no event shall the aggregate "interest" (as that term is defined in Section 347 of the Criminal Code (Canada)) with respect to any Loans by or on behalf of Canadian Lender exceed the effective annual rate of interest on the "credit advanced" (as defined therein) lawfully permitted under Section 347 of the Criminal Code (Canada). The effective annual rate of interest for such purpose shall be determined in accordance with generally accepted actuarial practices and principles over the term of the applicable Loan by or on behalf of Canadian Lender, and in the event of a dispute, a certificate of a Fellow of the Canadian Institute of Actuaries appointed by Agent will be conclusive for the purposes of such determination. (g) A certificate of an authorized signing officer of Agent as to each rate of interest payable hereunder from time to time absent manifest error shall be conclusive evidence of such rate. (h) For greater certainty, unless otherwise specified in this Agreement or any of the other Financing Agreements, as applicable, whenever any amount is payable under this 33

Agreement or any of the other Financing Agreements by Borrowers as interest or as a fee which requires the calculation of an amount using a percentage per annum, each party to this Agreement acknowledges and agrees that such amount shall be calculated as of the date payment is due without application of the "deemed reinvestment principle" or the "effective yield method." As an example, when interest is calculated and payable monthly, the rate of interest payable per month is one twelfth (1/12) of the stated rate of interest per annum. 3.2 Agent Fees. Borrowers shall pay to Agent the fees set forth in the Agent fee letter dated as of the date hereof between Agent and Borrowers. 3.3 Lender Fees. Borrowers shall pay to Agent for the benefit of Lenders the fees set forth in the Lender fee letter dated as of the date hereof between Agent and Borrowers. 3.4 Unused Line Fee. Borrowers shall pay to Agent for the ratable benefit of Lenders monthly an unused line fee at a rate equal to one quarter of one (.25%) percent per annum calculated upon the amount by which the Revolving Loan Limit exceeds the average daily principal balance of the outstanding Revolving Loans and Letter of Credit Accommodations during the immediately preceding month (or part thereof) while this Agreement is in effect and for so long thereafter as any of the Obligations are outstanding, which fee shall be payable on the first day of each month in arrears. 3.5 Changes in Laws and Increased Costs of Loans. (a) Notwithstanding anything to the contrary contained herein, the Eurodollar Rate Loans made by a Lender shall, upon notice by such Lender to Borrowers, convert to Prime Rate Loans in the event that (i) any change in applicable law or regulation (or the interpretation or administration thereof) shall (A) make it unlawful for such Lender, or any participant with such Lender or Reference Bank to make or maintain Eurodollar Rate Loans or to comply with the terms hereof in connection with the Eurodollar Rate Loans, or (B) shall result in the increase in the costs to such Lender or any participant with such Lender or Reference Bank of making or maintaining any Eurodollar Rate Loans by an amount deemed by such Lender to be material, or (C) reduce the amounts received or receivable by such Lender in respect thereof, by an amount deemed by such Lender to be material; or (ii) the cost to such Lender, or any participant with such Lender or Reference Bank of making or maintaining any Eurodollar Rate Loans shall otherwise increase by an amount deemed by such Lender to be material. Borrowers shall pay to such Lender, upon demand by such Lender (or such Lender may, at its option, charge any loan account of Borrowers) any amounts required to compensate such Lender or any participant with such Lender or Reference Bank for any loss (including loss of anticipated profits), cost or expense incurred by such person as a result of the foregoing, including, without limitation, any such loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such person to make or maintain the Eurodollar Rate Loans or any portion thereof. A certificate of such Lender setting forth the basis for the determination of such amount necessary to compensate such Lender as aforesaid shall be delivered to Borrowers and shall be conclusive, absent manifest error. (b) If any payments or prepayments in respect of the Eurodollar Rate Loans are received by Lenders other than on the last day of the applicable Interest Period (whether pursuant to acceleration, upon maturity or otherwise), including any payments pursuant to the application of collections under Section 6.3 or any other payments made with the proceeds of 34

Collateral, Borrowers shall pay to Lenders upon demand by Agent (or Agent or any Lender may, at their option, charge any loan account of Borrowers) any amounts required to compensate Lenders, the Reference Bank or any participant with any Lender for any additional loss (including loss of anticipated profits), cost or expense incurred by such person as a result of such prepayment or payment, including, without limitation, any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such person to make or maintain such Eurodollar Rate Loans or any portion thereof.

SECTION 5. GRANT AND PERFECTION OF SECURITY INTEREST. 5.1 Grant of Security Interest. (a) To secure payment and performance of all Obligations, each Borrower hereby grants to Agent for the benefit of itself and each Lender a continuing security interest in, a lien upon, and a right of set off against, and hereby assigns to Agent for the benefit of itself and each Lender as security, and each Canadian Borrower hereby grants to Agent a continuing security interest in, a lien upon, and a right of set off against, and hereby assigns to Agent for the benefit of itself and each Lender as security, all personal and real property and fixtures and interests in property and fixtures of each Borrower, whether now owned or hereafter acquired or existing, and wherever located (together with all other collateral security for the Obligations at any time granted to or held or acquired by Agent for the benefit of itself and each Lender or by any Lender, collectively, the "Collateral"), including: 38

(b) Notwithstanding anything to the contrary set forth in 5.1(a) above, the types of collateral described in such Section shall not include the last day of the term of any lease or agreement to which any Canadian Borrower is a party therefor but upon enforcement of the security interest the applicable Canadian Borrower shall stand possessed of such last day in trust to assign the same to any person acquiring the term of the lease or agreement therefor. 5.2 Perfection of Security Interests. (a) Each Borrower irrevocably and unconditionally authorizes Agent (or its agent) to file at any time and from time to time such financing statements with respect to the Collateral naming Agent or its designee as the secured party and each such Borrower as debtor, as Agent may require, and including any other information with respect to each such Borrower or otherwise required by part 5 of Article 9 of the Uniform Commercial Code of such jurisdiction or under the PPSA as Agent may determine, together with any amendment and continuations with respect thereto, which authorization shall apply to all financing statements filed on, prior to or after the date hereof. Each Borrower hereby ratifies and approves all financing statements naming Agent or its designee as secured party and each such Borrower as debtor with respect to the Collateral (and any amendments with respect to such financing statements) filed by or on behalf of Agent prior to the date hereof and ratifies and confirms the authorization of Agent to file such financing statements (and amendments, if any). Each Borrower hereby authorizes Agent to adopt on behalf of each such Borrower any symbol required for authenticating any electronic filing. In no event shall any Borrower at any time file, or permit or cause to be filed, any correction statement or termination statement with respect to any financing statement (or amendment or continuation with respect thereto) naming Agent or its designee as secured party and any Borrower as debtor. (b) Borrowers do not have any chattel paper (whether tangible or electronic) or instruments as of the date hereof, except as set forth in the Information Certificates. In the event that any Borrower shall be entitled to or shall receive any chattel paper or instrument after the date hereof, Borrowers shall promptly notify Agent thereof in writing. Promptly upon the receipt thereof by or on behalf of any Borrower (including by any agent or representative), Borrowers shall deliver, or cause to be delivered to Agent, all tangible chattel paper and instruments that any Borrower may at any time acquire, accompanied by such instruments of transfer or assignment duly executed in blank as Agent may from time to time specify, in each case, except as Agent may otherwise agree. At Agent's option, Borrowers shall, or Agent may at any time on behalf of Borrowers, cause the original of any such instrument or chattel paper to be conspicuously marked in a form and manner acceptable to Agent with the following legend 40

referring to chattel paper or instruments as applicable: "This [chattel paper][instrument] is subject to the security interest of Congress Financial Corporation (New England), as agent for itself and certain other lending institutions, and any sale, transfer, assignment or encumbrance of this [chattel paper][instrument] violates the rights of such secured party." (c) In the event that any Borrower shall at any time hold or acquire an interest in any electronic chattel paper or any "transferable record" (as such term is defined in Section 201 of the Federal Electronic Signatures in Global and National Commerce Act or in Section 16 of the Uniform Electronic Transactions Act as in effect in any relevant jurisdiction), Borrowers shall promptly notify Agent thereof in writing. Promptly upon Agent's request, Borrowers shall take, or cause to be taken, such actions as Agent may reasonably request to give Agent control of such electronic chattel paper under Section 9-105 of the UCC and control of such transferable record under Section 201 of the Federal Electronic Signatures in Global and National Commerce Act or, as the case may be, Section 16 of the Uniform Electronic Transactions Act, as in effect in such jurisdiction. (d) Borrowers do not have any deposit accounts as of the date hereof, except as set forth in the Information Certificates. Borrowers shall not, directly or indirectly, after the date hereof open, establish or maintain any deposit account unless each of the following conditions is satisfied: (i) Agent shall have received not less than five (5) Business Days prior written notice of the intention of any Borrower to open or establish such account which notice shall specify in reasonable detail and specificity acceptable to Agent the name of the account, the owner of the account, the name and address of the bank or other financial institution at which such account is to be opened or established, the individual at such bank or other financial institution with whom such Borrower is dealing and the purpose of the account, (ii) the bank or other financial institution where such account is opened or maintained shall be acceptable to Agent, and (iii) on or before the opening of such deposit account, such Borrower shall, as Agent may specify, either (A) deliver to Agent a Deposit Account Control Agreement with respect to such deposit account duly authorized, executed and delivered by such Borrower and the bank at which such deposit account is opened and maintained, or (B) arrange for Agent to become the customer of the bank with respect to the deposit account on terms and conditions acceptable to Agent. The terms of this subsection (d) shall not apply to deposit accounts specifically and exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of Borrowers' salaried employees. (e) Borrowers do not own or hold, directly or indirectly, beneficially or as record owner or both, any investment property, as of the date hereof, or have any investment account, securities account, commodity account or other similar account with any bank or other financial institution or other securities intermediary or commodity intermediary as of the date hereof, in each case except as set forth in the Information Certificates. (i) In the event that any Borrower shall be entitled to or shall at any time after the date hereof hold or acquire any certificated securities, such Borrower shall promptly endorse, assign and deliver the same to Agent, accompanied by such instruments of transfer or assignment duly executed in blank as Agent may from time to time specify. If any securities, now or hereafter acquired by Borrower are uncertificated and are issued to such Borrower or its nominee directly by the issuer thereof, such Borrower 41

shall immediately notify Agent thereof and shall, as Agent may specify, either (A) cause the issuer to agree to comply with instructions from Agent as to such securities, without further consent of such Borrower or such nominee, or (B) arrange for Agent to become the registered owner of the securities. (ii) Borrowers shall not, directly or indirectly, after the date hereof open, establish or maintain any investment account, securities account, commodity account or any other similar account (other than a deposit account) with any securities intermediary or commodity intermediary unless each of the following conditions is satisfied: (A) Agent shall have received not less than five (5) Business Days prior written notice of the intention of a Borrower to open or establish such account which notice shall specify in reasonable detail and specificity acceptable to Agent the name of the account, the owner of the account, the name and address of the securities intermediary or commodity intermediary at which such account is to be opened or established, the individual at such intermediary with whom such Borrower is dealing and the purpose of the account, (B) the securities intermediary or commodity intermediary (as the case may be) where such account is opened or maintained shall be acceptable to Agent, and (C) on or before the opening of such investment account, securities account or other similar account with a securities intermediary or commodity intermediary, such Borrower shall, as Agent may specify, either (1) execute and deliver, and cause to be executed and delivered to Agent, an Investment Property Control Agreement with respect thereto duly authorized, executed and delivered by such Borrower and such securities intermediary or commodity intermediary, or (2) arrange for Agent to become the entitlement holder with respect to such investment property on terms and conditions acceptable to Agent. (f) No Borrower is the beneficiary or otherwise entitled to any right to payment under any letter of credit, banker's acceptance or similar instrument as of the date hereof, except as set forth in the Information Certificates. In the event that any Borrower shall be entitled to or shall receive any right to payment under any letter of credit, banker's acceptance or any similar instrument, whether as beneficiary thereof or otherwise after the date hereof, such Borrower shall promptly notify Agent thereof in writing. Each Borrower shall immediately, as Agent may specify, either (i) deliver, or cause to be delivered to Agent, with respect to any such letter of credit, banker's acceptance or similar instrument, the written agreement of the issuer and any other nominated person obligated to make any payment in respect thereof (including any confirming or negotiating bank), in form and substance satisfactory to Agent, consenting to the assignment of the proceeds of the letter of credit to Agent by such Borrower and agreeing to make all payments thereon directly to Agent or as Agent may otherwise direct, or (ii) cause Agent to become, at Borrowers' expense, the transferee beneficiary of the letter of credit, banker's acceptance or similar instrument (as the case may be). (g) No Borrower has commercial tort claims as of the date hereof, except as set forth in the Information Certificates. In the event that any Borrower shall at any time after the date hereof have any commercial tort claims, such Borrower shall promptly notify Agent 42

thereof in writing, which notice shall (i) set forth in reasonable detail the basis for and nature of such commercial tort claim, and (ii) include the express grant by such Borrower to Agent of a security interest in such commercial tort claim (and the proceeds thereof). In the event that such notice does not include such grant of a security interest, the sending thereof by such Borrower to Agent shall be deemed to constitute such grant to Agent. Upon the sending of such notice, any commercial tort claim described therein shall constitute part of the Collateral and shall be deemed included therein. Without limiting the authorization of Agent provided in Section 5.2(a) hereof or otherwise arising by the execution by Borrowers of this Agreement, Agent is hereby irrevocably authorized from time to time and at any time to file such financing statements naming Agent or its designee as secured party and each Borrower as debtor, or any amendments to any financing statements, covering any such commercial tort claim as Collateral. In addition, Borrowers shall promptly upon Agent's request, execute and deliver, or cause to be executed and delivered, to Agent such other agreements, documents and instruments as Agent may require in connection with such commercial tort claim. (h) Borrowers do not have any goods, documents of title or other Collateral in the custody, control or possession of a third party as of the date hereof, except as set forth in the Information Certificates and except for goods located in the United States or Canada in transit to a location of Borrowers permitted herein or in the ordinary course of business of Borrowers in the possession of the carrier transporting such goods. In the event that any goods, documents of title or other Collateral are at any time after the date hereof in the custody, control or possession of any other person not referred to in the Information Certificates or such carriers, Borrowers shall promptly notify Agent thereof in writing. Promptly upon Agent's request, Borrowers shall deliver to Agent a Collateral Access Agreement duly authorized, executed and delivered by such person and Borrower. (i) If a Default or an Event of Default shall occur and be continuing or if the aggregate Excess Availability of all Borrowers is less than the US Dollar Equivalent of $10,000,000 for ten (10) consecutive days or ten (10) days in any thirty (30) day period, upon the request of Agent, (i) Borrowers shall cause Agent's name to be noted as secured party on each certificate of title for titled goods of the Borrowers, if, as determined by Agent, such notation is a condition to attachment, priority or perfection or ability of Agent to enforce, the security interest of Agent in such Collateral, (ii) Borrowers shall execute and deliver to Agent mortgages, charges, hypothecs, deeds of trust or deeds to secure debt, as Agent may determine, in form and substance satisfactory to Agent and in forms appropriate for recording in the real estate records of the jurisdictions in which Borrowers' Real Property is located granting to Agent a lien and mortgage on and security interest in such Real Property, fixtures or other property and cause to be delivered to Agent, in form and substance satisfactory to Agent, valid and effective title insurance policies issued by a company and agent satisfactory to Agent insuring the priority, amount and sufficiency of such mortgages, charges, hypothecs, deeds of trust or deeds to secure debt and containing such legally available endorsements, assurances and affirmative coverages as Agent may reasonably require, with opinions of counsel in form and substance satisfactory to Agent as Agent may reasonably require. (j) Borrowers shall take any other actions reasonably requested by Agent from time to time to cause the attachment, perfection and first priority of, and the ability of Agent to enforce, the security interest of Agent in any and all of the Collateral, including, without limitation, (i) executing, delivering and, where appropriate, filing financing statements 43

and amendments relating thereto under the UCC, the PPSA or other applicable law, to the extent, if any, that a Borrower's signature thereon is required therefor, (ii) complying with any provision of any statute, regulation or treaty of the United States or Canada as to any Collateral if compliance with such provision is a condition to attachment, perfection or priority of, or ability of Agent to enforce, the security interest of Agent in such Collateral, or (iii) obtaining the consents and approvals of any Governmental Authority or third party, including, without limitation, any consent of any licensor, lessor or other person obligated on such Collateral, and taking all actions required by any earlier versions of the UCC, the PPSA or by other law, as applicable in any relevant jurisdiction. 5.3 Exclusion from Collateral of Cash Collateral Maintained at L/C Issuer Under Cash Collateral Control Agreement. Notwithstanding anything to the contrary contained in Section 5.1 above, the types or items of Collateral described in such Section shall not include the cash and Cash Equivalents deposited in the collateral account maintained at the L/C Issuer (as such term is defined in the Term Loan Agreement) pursuant to the Cash Collateral Control Agreement among Borrowers, Term Loan Agent and the L/C Issuer entered into under the Term Loan Agreement that secures the letters of credit issued by the L/C Issuer from time to time. SECTION 6. COLLECTION AND ADMINISTRATION. 6.1 Borrowers' Loan Account. Agent shall maintain one or more loan account(s) on its books in which shall be recorded (a) all Loans, Letter of Credit Accommodations and other Obligations and the Collateral, (b) all payments made by or on behalf of Borrowers, and (c) all other appropriate debits and credits as provided in this Agreement, including fees, charges, costs, expenses and interest. All entries in the loan account(s) shall be made in accordance with Agent's customary practices as in effect from time to time. 6.2 Statements. Agent shall render to Borrowers each month a statement setting forth the balance in the Borrowers' loan account(s) maintained by Agent for Borrowers pursuant to the provisions of this Agreement, including principal, interest, fees, costs and expenses. Each such statement shall be subject to subsequent adjustment by Agent but shall, absent manifest errors or omissions, be considered correct and deemed accepted by Borrowers and conclusively binding upon Borrowers as an account stated except to the extent that Agent receives a written notice from Borrowers of any specific exceptions of Borrower thereto within thirty (30) days after the date such statement has been mailed by Agent. Until such time as Agent shall have rendered to Borrowers a written statement as provided above, the balance in Borrowers' loan account(s) shall be presumptive evidence of the amounts due and owing to Agent and Lenders by Borrowers. 6.3 Collection of Accounts. (a) Borrowers shall establish and maintain, at their expense, blocked accounts or lockboxes and related blocked accounts (in either case, "Blocked Accounts"), as Agent may specify, with such banks as are acceptable to Agent into which Borrowers shall promptly deposit and direct their account debtors to directly remit all payments on Receivables and all payments constituting proceeds of other Revolving Loan Priority Collateral in the identical form in which such payments are made, whether by cash, check or other manner. Borrowers shall deliver, or cause to be delivered to Agent, a Depository Account Control Agreement duly authorized, executed and delivered by each bank where a Blocked Account is maintained as provided in Section 5.2 hereof or at any time and from time to time Agent may become bank's customer with 44

respect to the Blocked Accounts and promptly upon Agent's request, Borrowers shall execute and deliver such agreements or documents as Agent may require in connection therewith. Borrowers agree that all payments made to such Blocked Accounts or other funds received and collected by Agent, whether in respect of the Receivables or other Revolving Loan Priority Collateral or otherwise shall be treated as payments to Agent for the benefit of itself and Lenders in respect of the Obligations and therefore shall constitute the property of Agent and Lenders to the extent of the then outstanding Obligations. (b) For purposes of calculating the amount of the Loans available to Borrowers, such payments will be applied (conditional upon final collection) to the Obligations on the Business Day of receipt by Agent of immediately available funds in the Agent Payment Account or the Canadian Payment Account (as the case may be) provided such payments and notice thereof are received in accordance with Agent's usual and customary practices as in effect from time to time and within sufficient time to credit Borrowers' loan account(s) on such day, and if not, then on the next Business Day. For the purposes of calculating interest on the Obligations, such payments or other funds received will be applied (conditional upon final collection) to the Obligations one (1) Business Day following the date of receipt of immediately available funds by Agent in the Agent Payment Account or the Canadian Payment Account (as the case may be) provided such payments or other funds and notice thereof are received in accordance with Agent's usual and customary practices as in effect from time to time and within sufficient time to credit Borrowers' loan account on such day, and if not, then on the next Business Day and such amount shall be retained by the Agent. In the event that at any time or from time to time there are no Loans outstanding, Borrowers shall pay an administrative charge to Agent in an amount equivalent to the interest Borrowers would have paid for such Business Day had there been Loans outstanding on such day which charge shall be paid to Agent. (c) Each Borrower and its shareholders, directors, employees, agents, Subsidiaries or other Affiliates shall, acting as trustee for Agent and Lenders, receive, as the property of Agent and Lenders, any monies, checks, notes, drafts or any other payment relating to and/or proceeds of Accounts or other Revolving Loan Priority Collateral which come into their possession or under their control and immediately upon receipt thereof, shall deposit or cause the same to be deposited in the Blocked Accounts, or remit the same or cause the same to be remitted, in kind, to Agent for the benefit of itself and Lenders. In no event shall the same be commingled with any Borrower's own funds. Each Borrower agrees to reimburse Agent and Lenders on demand for any amounts owed or paid to any bank at which a Blocked Account is established or any other bank or person involved in the transfer of funds to or from the Blocked Accounts arising out of Agent's or any Lender's payments to or indemnification of such bank or person. The obligation of Borrowers to reimburse Agent and Lenders for such amounts pursuant to this Section 6.3 shall survive the termination or non-renewal of this Agreement. (d) No Borrower shall permit any payment relating to or constituting proceeds of Collateral other than Revolving Loan Priority Collateral to be deposited into any Blocked Account or the Agent Payment Account or the Canadian Payment Account. All payments relating to or constituting proceeds of Collateral other than Revolving Loan Priority Collateral shall be made to the account of the Term Loan Agent set forth in the Term Loan Agreement or as otherwise provided under the Term Loan Agreement. Borrowers shall immediately notify Agent if any payment or deposit is made contrary to this provision. 45

6.4 Payments. (a) All Obligations of US Borrowers shall be payable to the Agent Payment Account as provided in Section 6.3 and all Obligations of Canadian Borrowers shall be payable to the Canadian Payment Account or, in each case such other place as Agent may designate from time to time. Agent shall apply payments received or collected from Borrowers or for the account of Borrowers (including the monetary proceeds of collections or of realization upon any Collateral) under the US Credit Facility or Canadian Credit Facility, as applicable, as follows: first, to pay any fees, indemnities or expense reimbursements then due to Agent or Lenders from Borrowers; second, to pay interest due in respect of any Loans; third, to pay principal due on any SwingLine Loans, Overadvances and Loans made by Agent pursuant to Section 6.6 thereof; fourth, to pay principal due in respect of the Revolving Loans; fifth, to pay or prepay any other Obligations whether or not then due, in such order and manner as Agent determines. Notwithstanding anything to the contrary contained in this Agreement, (i) unless so directed by Borrowers, or unless a Default or an Event of Default shall exist or have occurred and be continuing, Lenders shall not apply any payments which they receive to any Eurodollar Rate Loans, except (A) on the expiration date of the Interest Period applicable to any such Eurodollar Rate Loans, or (B) in the event that there are no outstanding Prime Rate Loans, and (ii) to the extent Borrowers use any proceeds of the Loans or Letter of Credit Accommodations to acquire rights in or the use of any Collateral or to repay any Indebtedness used to acquire rights in or the use of any Collateral, payments in respect of the obligations shall be deemed applied first to the Obligations arising from Loans and Letter of Credit Accommodations that were not used for such purposes and second to the Obligations arising from Loans and Letter of Credit Accommodations the proceeds of which were used to acquire rights in or the use of any Collateral in the chronological order in which Borrowers acquired such rights or use. (b) At Agent's option, all principal, interest, fees, costs, expenses and other charges provided for in this Agreement or the other Financing Agreements may be charged directly to the loan account(s) of Borrowers. Borrowers shall make all payments to Agent and Lenders on the Obligations free and clear of, and without deduction or withholding for or on account of, any setoff, counterclaim, defense, duties, taxes, levies, imposts, fees, deductions, withholding, restrictions or conditions of any kind. If after receipt of any payment of, or proceeds of Collateral applied to the payment of, any of the Obligations, Agent or any Lender is required to surrender or return such payment or proceeds to any Person for any reason, then the Obligations intended to be satisfied by such payment or proceeds shall be reinstated and continue and this Agreement shall continue in full force and effect as if such payment or proceeds had not been received. Borrowers shall be liable to pay to Agent and each Lender, and does hereby indemnify and hold Agent and each Lender harmless for the amount of any payments or proceeds surrendered or returned. This Section 6.4 shall remain effective notwithstanding any contrary action which may be taken by Lender in reliance upon such payment or proceeds. This Section 6.4 shall survive the payment of the Obligations and the termination or non-renewal of this Agreement. 6.5 Authorization to Make Loans. (a) Agent and Lenders are authorized to make the Loans and provide the Letter of Credit Accommodations based upon telephonic or other instructions received from anyone purporting to be an authorized officer of Borrower Representative (as set forth in the 46

Information Certificate) or other authorized person or, at the discretion of Agent, if such Loans are necessary to satisfy any Obligations. All requests for Loans or Letter of Credit Accommodations hereunder shall be made to the Agent and shall specify the date on which the requested advance is to be made or Letter of Credit Accommodations established (which day shall be a Business Day) and the amount of the requested Loan. Requests received after 11:00 a.m. Boston, Massachusetts time on any day shall be deemed to have been made as of the opening of business on the immediately following Business Day. All Loans and Letter of Credit Accommodations under this Agreement shall be conclusively presumed to have been made to, and at the request of and for the benefit of, Borrowers when deposited to the credit of Borrowers or otherwise disbursed or established in accordance with the instructions of Borrowers or in accordance with the terms and conditions of this Agreement; and (b) All Loans provided to US Borrowers shall be in or denominated in US Dollars and shall be disbursed only to bank accounts in the United States of America and all Loans provided to Canadian Borrowers shall be in or denominated in either Canadian Dollars or US Dollars as Canadian Borrowers may specify, except as Canadian Lender may otherwise specifically agree in writing and shall be disbursed only to bank accounts in Canada. Set forth on Schedule 8.10 to the Information Certificates are the bank accounts of each Borrower used by such Borrower for making payments of its Indebtedness and other obligations to which, as of the date hereof, proceeds of Loans may be disbursed. 6.6 Payment by Lenders and Settlement of Loans. Each Lender shall, not later than 12:00 p.m. (Boston time) on such requested borrowing date, wire to a bank designated by Agent the amount of that Lender's Pro Rata Share of the requested Revolving Loan. The failure of any Lender to make the Revolving Loans required to be made by it shall not release any other Lender of its obligations hereunder to make its Revolving Loan. Neither Agent nor any other Lender shall be responsible for the failure of any other Lender to make the Revolving Loan to be made by such other Lender. Unless the Agent has received notice from a Lender that such Lender does not intend to fund a Revolving Loan and the basis for such action prior to 12:00 noon on the Business Day prior to the date any Revolving Loan is to be made, Agent shall be entitled to assume that all Lenders will make Revolving Loans as required hereunder and to make such Revolving Loans to the Borrowers. The foregoing notwithstanding, Agent, in its sole discretion, may from time to time make Revolving Loans on behalf of any or all Lenders including, without limitation, Revolving Loans with respect to Letter of Credit Accommodations that may be drawn. In such event, the Lenders on behalf of whom Agent made the Revolving Loans, shall reimburse Agent for the amount of such Revolving Loan made on its behalf, on a weekly (or more frequent, as determined by Agent in its sole discretion) basis. Settlements shall continue to occur during the continuance of a Default or an Event of Default and whether or not the applicable conditions in Section 4 have been satisfied. On each such settlement date, each such Lender shall pay to Agent, the net amount owing to Agent in connection with such settlement, as determined by Agent, including without limitation, amounts relating to Loans, fees, interest and other amounts payable hereunder. If a Lender fails to pay the settlement amount due to Agent on the settlement date specified by Agent, such Lender shall pay to Agent on demand an amount equal to the product of (i) such amount times (ii)(A) the Federal Funds Rate during the period from and including the third day after such payment is required to be made, and (B) thereafter, the Interest Rate applicable to Prime Rate Loans to the date on which such payment is immediately available to Agent, times (iii) a fraction, the numerator of which is the number of days that elapsed from and including such settlement date to the date such settlement amount is 47

immediately available to Agent and the denominator is 360. In addition to the foregoing, if the amount of any such Lender's Pro Rata Share of such Revolving Loans is not made available to Agent on any settlement date, the Agent shall be entitled to recover such amount from Borrowers upon demand with interest thereon at the Interest Rate applicable to Prime Rate Loans. 6.7 Use of Proceeds. Borrowers shall use the initial proceeds of the Loans provided by Lenders to Borrower hereunder only for: (a) payments to each of the persons listed in the disbursement direction letter furnished by Borrowers to Lenders on or about the date hereof including with respect to payments to be made to the Sellers under the Purchase Agreements, to refinance existing indebtedness of Borrowers and pay the prepayment and defeasance costs in connection therewith and for fees, costs and expenses relating thereto and (b) costs, expenses and fees in connection with the preparation, negotiation, execution and delivery of this Agreement and the other Financing Agreements. All other Loans made or Letter of Credit Accommodations provided by Agent, Lenders and Reference Bank to Borrower pursuant to the provisions hereof shall be used by Borrowers only for general operating, working capital and other proper corporate purposes of Borrowers not otherwise prohibited by the terms hereof. None of the proceeds will be used, directly or indirectly, for the purpose of purchasing or carrying any margin security or for the purposes of reducing or retiring any indebtedness which was originally incurred to purchase or carry any margin security or for any other purpose which might cause any of the Loans to be considered a "purpose credit" within the meaning of Regulation U of the Board of Governors of the Federal Reserve System, as amended. 6.8 Taxes. (a) Any and all payments by or on behalf of a Borrower hereunder and under any other Financing Agreement shall be made, in accordance with Section 6.4, free and clear of and without deduction for any and all Taxes, excluding the following (collectively, "Excluded Taxes"): (i) income taxes imposed on the net income or capital of Agent or any Lender (or any transferee or assignee of such Lender, including any Participant, any such transferee or assignee being referred to as a "Transferee") in the jurisdiction of Agent's or such Lender's applicable lending office or jurisdiction of organization or any political subdivision thereof, and (ii) franchise or similar taxes imposed on or determined by reference to the net income of Agent or any Lender (or Transferee), in each case by the United States of America or by the jurisdiction under the laws of which such Lender (or Transferee) (A) is organized or any political subdivision thereof, (B) has its applicable lending office located or (C) is otherwise doing business. In addition, Borrowers agree to pay to the relevant Governmental Authority in accordance with applicable law any Other Taxes. (b) If a Borrower shall be required by law to deduct or withhold in respect of any Taxes or Other Taxes (other than Excluded Taxes) from or in respect of any sum payable hereunder to Agent or any Lender, then: (i) the sum payable shall be increased as necessary so that after making all required deductions and withholdings (including deductions and withholdings applicable to additional sums payable under this Section) such Lender (or Agent on behalf of such Lender or itself, as the case may be) receives an amount equal to the sum it would have received had no such deductions or withholdings been made; 48

(ii) such Borrower shall make such deductions and withholdings; (iii) such Borrower shall pay the full amount deducted or withheld to the relevant taxing authority or other authority in accordance with applicable law; and (iv) to the extent not paid to Agent and Lenders pursuant to clause (i) above, Borrowers shall also pay to Agent or any Lender, at the time interest is paid, all additional amounts which Agent or any Lender specifies as necessary to preserve the after-tax yield such Lender would have received if such Taxes or Other Taxes had not been imposed. (c) Within thirty (30) days after the date of any payment by a Borrower of Taxes or Other Taxes, upon Agent's request, such Borrower shall furnish to Agent the original or a certified copy of a receipt evidencing payment thereof, or other evidence of payment reasonably satisfactory to Agent. (d) Borrowers any will indemnify Agent and each Lender (or Transferee) for the full amount of Taxes and Other Taxes paid by Agent or such Lender (or Transferee, as the case may be). If Agent or such Lender (or Transferee) receives a refund in respect of any Taxes or Other Taxes for which Agent or such Lender (or Transferee) has received payment from a Borrower hereunder, so long as no Default or Event of Default shall exist or have occurred and be continuing and Excess Availability in excess of such refund exists, Agent or such Lender (as the case may be) shall credit to the loan account of the applicable Borrower the amount of such refund plus any interest received (but only to the extent of indemnity payments made, or additional amounts paid, by or on behalf of such Borrower under this Section 6.8 with respect to the Taxes or Other Taxes giving rise to such refund). If a Lender (or any Transferee) claims a tax credit in respect of any Taxes for which it has been indemnified by a Borrower pursuant to this Section 6.8, such Lender will apply the amount of the actual dollar benefit received by such Lender as a result thereof, as reasonably calculated by such Lender and net of all expenses related thereto, to the Loans made by such Lender. If Taxes or Other Taxes were not correctly or legally asserted, Agent or such Lender shall, upon Parent's request and at the expense of Parent, provide such documents to Parent in form and substance satisfactory to Agent, as Parent may reasonably request, to enable such Borrower to contest such Taxes or Other Taxes pursuant to appropriate proceedings then available to such Borrower (so long as providing such documents shall not, in the good faith determination of Agent or the Lender, have a reasonable likelihood of resulting in any liability of Agent or such Lender for which Agent has not established a Reserve). The indemnity provided for herein shall survive the payment of the Obligations and the termination of this Agreement. A certificate as to the amount of such payment or liability and setting forth in reasonable detail the calculation and basis for such payment or liability delivered to Parent by a Lender or by Agent on its own behalf or on behalf of a Lender, shall be conclusive, absent manifest error. (e) Each Transferee of a US Lender or Agent that is not a United States person within the meaning of Section 7701(a)(30) of the Code and that is a US Lender or claims indemnification or additional amounts under this Section 6.8 (a "Non-U.S. Person") shall deliver to Parent two (2) copies of the applicable United States Internal Revenue Service Form W-8 wherein such Transferee claims entitlement to a complete exemption from U.S. federal income withholding tax on all payments by or on behalf of Parent under this Agreement and the other Financing Agreements. Such forms shall be delivered by any Non-U.S. Person receiving 49

payments by or on behalf of Parent on or before the date it becomes a party to this Agreement (or, in the case of a Transferee that is a Participant, on or before the date such Participant becomes a Transferee hereunder) and on or before the date, if any, such Non-U.S. Person changes its applicable lending office by designating a different lending office (a "New Lending Office"). In addition, a Non-U.S. Person shall upon written notice from Parent promptly deliver such new forms as are required by the relevant Governmental Authority to claim exemption from, or reduction in the rate of, U.S. Federal withholding tax upon the obsolescence or invalidity of any form previously delivered by such Non-U.S. Person.

(a) At any time an Event of Default exists or has occurred and is continuing, Agent shall have all rights and remedies provided in this Agreement, the other Financing Agreements, the UCC, PPSA and other applicable law, all of which rights and remedies may be exercised without notice to or consent by any Borrower or any Obligor, except as such notice or consent is expressly provided for hereunder or required by applicable law. All rights, remedies and powers granted to Lender hereunder, under any of the other Financing Agreements, the UCC, PPSA or other applicable law, are cumulative, not exclusive and enforceable, in Agent's discretion, alternatively, successively, or concurrently on any one or more occasions, and shall include, without limitation, the right to apply to a court of equity for an injunction to restrain a breach or threatened breach by any Borrower of this Agreement or any of the other Financing Agreements. Agent may, at any time or times, proceed directly against any Borrower or any Obligor to collect the Obligations without prior recourse to the Collateral. 77

(b) Without limiting the foregoing, at any time an Event of Default exists or has occurred and is continuing, Agent may, in its discretion and shall, upon the request of the Majority Lenders, without limitation, (i) accelerate the payment of all Obligations and demand immediate payment thereof to Agent and Lenders (provided, that, upon the occurrence of any Event of Default described in Sections 10.1(g) and 10.1(h), all Obligations shall automatically become immediately due and payable), (ii) with or without judicial process or the aid or assistance of others, enter upon any premises on or in which any of the Collateral may be located and take possession of the Collateral or complete processing, manufacturing and repair of all or any portion of the Collateral, (iii) require Borrowers, at Borrowers' expense, to assemble and make available to Agent (or Canadian Lender in the case of a Canadian Borrower) any part or all of the Collateral at any place and time designated by Agent (or Canadian Lender in the case of a Canadian Borrower), (iv) collect, foreclose, receive, appropriate, setoff (even though the Obligations may be unmatured and regardless of the adequacy of other Collateral) and realize upon any and all Collateral, (v) remove any or all of the Collateral from any premises on or in which the same may be located for the purpose of effecting the sale, foreclosure or other disposition thereof or for any other purpose, (vi) sell, lease, transfer, assign, deliver or otherwise dispose of any and all Collateral (including entering into contracts with respect thereto, public or private sales at any exchange, broker's board, at any office of Agent (or Canadian Lender in the case of a Canadian Borrower) or elsewhere) at such prices or terms as Agent (or Canadian Lender in the case of a Canadian Borrower) may deem reasonable, for cash, upon credit or for future delivery, with the Agent (or Canadian Lender in the case of a Canadian Borrower) having the right to purchase the whole or any part of the Collateral at any such public sale, all of the foregoing being free from any right or equity of redemption of Borrowers, which right or equity of redemption is hereby expressly waived and released by each Borrower and/or (vii) terminate this Agreement. If any of the Collateral is sold or leased by Agent (or Canadian Lender in the case of a Canadian Borrower) upon credit terms or for future delivery, the Obligations shall not be reduced as a result thereof until payment therefor is finally collected by Agent (or Canadian Lender in the case of a Canadian Borrower). If notice of disposition of Collateral is required by law, ten (10) days prior notice by Agent (or Canadian Lender in the case of a Canadian Borrower) to Borrowers designating the time and place of any public sale or the time after which any private sale or other intended disposition of Collateral is to be made, shall be deemed to be reasonable notice thereof and each Borrower waives any other notice. In the event Agent (or Canadian Lender in the case of a Canadian Borrower) institutes an action to recover any Collateral or seeks recovery of any Collateral by way of prejudgment remedy, each Borrower waives the posting of any bond which might otherwise be required. At any time an Event of Default exists or has occurred and is continuing, upon Agent's request, Borrowers will either, as Agent shall specify, furnish cash collateral to the issuer to be used to secure and fund Agent's reimbursement obligations to the issuer in connection with any Letter of Credit Accommodations or furnish cash collateral to Agent for the Letter of Credit Accommodations. Such cash collateral shall be in the amount equal to one hundred ten (110%) percent of the amount of the Letter of Credit Accommodations plus the amount of any fees and expenses payable in connection therewith through the end of the expiration of such Letter of Credit Accommodations. (c) Agent may (and shall, upon the request of the Majority Lenders), and Canadian Lender may (in the case of a Canadian Borrower) at any time or times that an Event of Default exists or has occurred and is continuing, enforce Borrowers' rights against any account debtor, secondary obligor or other obligor in respect of any of the Accounts or other Receivables. Without limiting the generality of the foregoing, Agent may at such time or times (i) notify any 78

or all account debtors, secondary obligors or other obligors in respect thereof that the Receivables have been assigned to Agent and that Agent has a security interest therein and Agent (or Canadian Lender in the case of a Canadian Borrower) may direct any or all accounts debtors, secondary obligors and other obligors to make payment of Receivables directly to Agent (or Canadian Lender in the case of a Canadian Borrower), (ii) extend the time of payment of, compromise, settle or adjust for cash, credit, return of merchandise or otherwise, and upon any terms or conditions, any and all Receivables or other obligations included in the Collateral and thereby discharge or release the account debtor or any secondary obligors or other obligors in respect thereof without affecting any of the Obligations, (iii) demand, collect or enforce payment of any Receivables or such other obligations, but without any duty to do so, and Agent and Lenders shall not be liable for the failure to collect or enforce the payment thereof nor for the negligence of its agents or attorneys with respect thereto, and (iv) take whatever other action Agent (or Canadian Lender in the case of a Canadian Borrower) may deem necessary or desirable for the protection of its interests. At any time that an Event of Default exists or has occurred and is continuing, at Agent's (or Canadian Lender in the case of a Canadian Borrower) request, all invoices and statements sent to any account debtor shall state that the Accounts and such other obligations have been assigned to Agent (or Canadian Lender in the case of a Canadian Borrower) and are payable directly and only to Agent, and Borrowers shall deliver to Agent such originals of documents evidencing the sale and delivery of goods or the performance of services giving rise to any Accounts as Agent (or Canadian Lender in the case of a Canadian Borrower) may require. In the event any account debtor returns Inventory when an Event of Default exists or has occurred and is continuing, Borrowers shall, upon Agent's (or Canadian Lender in the case of a Canadian Borrower) request, hold the returned Inventory in trust for Agent (or Canadian Lender in the case of a Canadian Borrower), segregate all returned Inventory from all of its other property, dispose of the returned Inventory solely according to Agent's instructions, and not issue any credits, discounts or allowances with respect thereto without Agent (or Canadian Lender in the case of a Canadian Borrower) prior written consent. (d) To the extent that applicable law imposes duties on Agent and Lenders to exercise remedies in a commercially reasonable manner (which duties cannot be waived under such law), Borrowers acknowledge and agree that it is not commercially unreasonable for Agent and Lenders (i) to fail to incur expenses reasonably deemed significant by Agent or Lenders to prepare Collateral for disposition or otherwise to complete raw material or work in process into finished goods or other finished products for disposition, (ii) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain consents of any Governmental Authority or other third party for the collection or disposition of Collateral to be collected or disposed of, (iii) to fail to exercise collection remedies against account debtors, secondary obligors or other persons obligated on Collateral or to remove liens or encumbrances on or any adverse claims against Collateral, (iv) to exercise collection remedies against account debtors and other persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (v) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (vi) to contact other persons, whether or not in the same business as Borrowers, for expressions of interest in acquiring all or any portion of the Collateral, (vii) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the collateral is of a specialized nature, (viii) to dispose of Collateral by utilizing Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets, (ix) to dispose of 79

assets in wholesale rather than retail markets, (x) to disclaim disposition warranties, (xi) to purchase insurance or credit enhancements to insure Agent and Lenders against risks of loss, collection or disposition of Collateral or to provide to Agent and Lenders a guaranteed return from the collection or disposition of Collateral, or (xii) to the extent deemed appropriate by Agent and Lenders, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist Lender in the collection or disposition of any of the Collateral. Borrowers acknowledge that the purpose of this Section is to provide non-exhaustive indications from Borrowers of what actions or omissions by Agent or Lenders would not be commercially unreasonable in Agent's and/or Lenders' exercise of remedies against the Collateral and that other actions or omissions by Agent and Lenders shall not be deemed commercially unreasonable solely on account of not being indicated in this Section. Without limitation of the foregoing, nothing contained in this Section shall be construed to grant any rights to Borrowers or to impose any duties on Agent or Lenders that would not have been granted or imposed by this Agreement or by applicable law in the absence of this Section. (e) For the purpose of enabling Agent or Lenders to exercise the rights and remedies hereunder, each Borrower hereby grants to Agent and Lenders, to the extent assignable, an irrevocable, non-exclusive license (exercisable without payment of royalty or other compensation to Borrowers) to use, assign, license or sublicense any of the trademarks, service-marks, trade names, business names, trade styles, designs, logos and other source of business identifiers and other Intellectual Property and general intangibles now owned or hereafter acquired by Borrowers, wherever the same maybe located, including in such license reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer programs used for the compilation or printout thereof. (f) For the purpose of enabling the Agent and Lenders to exercise their rights and remedies hereunder, Borrowers hereby grant to Agent an irrevocable right of access, easement and license (exercisable without payment of any fee or other compensation to Borrowers) to enter into any Real Property of Borrowers and to use and operate any Equipment or other goods thereon and to utilize any Inventory of the Borrower in connection with the fulfillment and completion of any contractual or other obligations of Borrowers to their account debtors and customers. (g) Agent may apply the cash proceeds of Collateral actually received by Agent from any sale, lease, foreclosure or other disposition of the Collateral first to reimburse Agent for all costs and expenses of collection or enforcement including attorneys' fees and legal expenses and second to payment of the Obligations, in whole or in part and in such order as Agent may elect or the Majority Lenders may direct, whether or not then due. Borrowers shall remain liable to Agent for the payment of any deficiency with interest at the highest rate provided for herein and all costs and expenses of collection or enforcement, including attorneys' fees and legal expenses. (h) Without limiting the foregoing, upon the occurrence of a Default or Event of Default, Agent may, at its option, and upon request of the Majority Lenders shall, without notice, (i) cease making Loans or arranging for Letter of Credit Accommodations or reduce the lending formulas or amounts of Revolving Loans and Letter of Credit Accommodations available to Borrowers (provided, that, upon the occurrence of any Event of Default described in Sections 10.1(g) or 10.1(h), the agreements of Agent and Lenders herein to make Loans and 80

arrange for Letter of Credit Accommodations shall automatically cease), and/or (ii) terminate any provision of this Agreement providing for any future Loans or Letter of Credit Accommodations to be made by Agent or Lenders to Borrowers. (i) Regardless of the adequacy of any collateral, if any of the Obligations are due and payable and have not been paid or any Event of Default shall have occurred, any deposits or other sums credited by or due from any Agent or Lender to any Borrower or any Obligor and any securities or other property of any Borrower or any Obligor in the possession of Agent or such Lender may, at any time, without demand or notice (any such notice being expressly waived by Borrowers and Obligors), in whole or in part, be applied to or set off by Agent and/or such Lender against the payment of Obligations and any and all other liabilities or obligations, direct, or indirect, absolute or contingent, due or to become due, now existing or hereafter arising, of Borrowers or Obligors to Agent and/or such Lender. Each of the Lenders agrees with each other Lender that (i) if an amount to be set off is to be applied to Obligations of Borrowers or Obligors to such Lender, such amount shall be applied ratably to all Obligations owed to such Lender, and (ii) if such Lender shall receive from Borrowers or Obligors or any other source, whether by voluntary payment, exercise of the right of setoff, counterclaim, cross action, or by enforcement of the claims evidenced by the Financing Agreements, by proceedings against the Borrowers or Obligors at law or in equity or by proof thereof in bankruptcy, reorganization, liquidation, receivership or similar proceedings, or otherwise, any amount in excess of its ratable portion of the payments received by all of the Lenders with respect to the Obligations, such Lender will make such disposition and arrangements with the Agent and other Lenders with respect to such excess, either by way of distribution, pro tanto assignment of claims, subrogation or otherwise as shall result in Agent and each Lender receiving in respect of the Obligations owed it, its proportionate payment as contemplated by this Agreement; provided that if all or any part of such excess payment is thereafter recovered from such Lender, such disposition and arrangements shall be rescinded and the amount restored to the extent of such recovery, but without interest. ANY AND ALL RIGHTS TO REQUIRE AGENT OR ANY LENDER TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF ANY BORROWER OR ANY OBLIGOR ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED. (j) Agent may appoint or reappoint by instrument in writing, any person or persons, whether an officer or officers or any employee or employees of Agent or not, to be a receiver or receivers (hereinafter called a "Receiver", which term when used herein shall include a receiver and manager) of any Collateral of any Canadian Borrower (including any interest, income or profits therefrom) and may remove any Receiver so appointed and appoint another in his/her stead. Any such Receiver shall, so far as concerns responsibility for his/her acts, be deemed the agent of the Canadian Borrower and not Agent, and Agent shall not be in any way responsible for any misconduct, negligence or non-feasance on the part of any such Receiver, his/her servants, agents or employees. Subject to the provisions of the instrument appointing him/her, any such Receiver shall have power to take possession of Collateral, to preserve Collateral or its value, to carry on or concur in carrying on all or any part of the business of the applicable Canadian Borrower and to sell, lease, license or otherwise dispose of or concur in selling, leasing, licensing or otherwise disposing of Collateral. To facilitate the foregoing powers, any such Receiver may, to the exclusion of all others, including the applicable Canadian 81

Borrower, enter upon, use and occupy all premises owned or occupied by the applicable Canadian Borrower wherein Collateral may be situate, maintain Collateral upon such premises, borrow money on a secured or unsecured basis and use Collateral directly in carrying on the applicable Canadian Borrower's business or as security for loans or advances to enable the Receiver to carry on applicable Canadian Borrower's business or otherwise, as such Receiver shall, in its discretion, determine. Except as may be otherwise directed by Agent, all proceeds of Collateral received from time to time by such Receiver in carrying out his/her appointment shall be received in trust for and paid over to Agent (or upon Agent's direction to Canadian Lender). Every such Receiver may, in the discretion of the Agent be vested with all or any of the rights and powers of the Agent. Agent may, either directly or through its agents or nominees, exercise any or all powers and rights given to a Receiver by virtue of the foregoing provisions of this paragraph. (k) On and after an Event of Default and for so long as the same is continuing, Borrowers shall pay all costs, charges and expenses incurred by Agent, any Lender or any Receiver or any nominee or agent of Agent, whether directly or for services rendered (including, without limitation, solicitor's costs on a solicitor and his own client basis, auditor's costs, other legal expenses and Receiver remuneration) in enforcing this Agreement or any other Financing Agreement and in enforcing or collecting Obligations and all such expenses together with any money owing as a result of any borrowing permitted hereby shall be a charge on the proceeds of realization and shall be secured hereby. SECTION 11. JURY TRIAL WAIVER; OTHER WAIVERS AND CONSENTS; GOVERNING LAW. 11.1 Governing Law; Choice of Forum; Service of Process; Jury Trial Waiver. (a) The validity, interpretation and enforcement of this Agreement and the other Financing Agreements (except as otherwise expressly provided therein) and any dispute arising out of the relationship between the parties hereto, whether in contract, tort, equity or otherwise, shall be governed by the internal laws of The Commonwealth of Massachusetts (without giving effect to principles of conflicts of law). (b) Each Borrower, Agent, and each Lender irrevocably consent and submit to the non-exclusive jurisdiction of the Suffolk County Superior Court of The Commonwealth of Massachusetts and any court to which an appeal may be taken therefrom and the United States District Court for the District of Massachusetts, whichever Agent may elect, and in addition, Borrowers irrevocably consent and submit to the non-exclusive jurisdiction of the Ontario Superior Court of Justice, in each case, whichever Agent may elect and waive any objection based on venue or forum non conveniens with respect to any action instituted therein arising under this Agreement or any of the other Financing Agreements or in any way connected with or related or incidental to the dealings of the parties hereto in respect of this Agreement or any of the other Financing Agreements or the transactions related hereto or thereto, in each case whether now existing or hereafter arising, and whether in contract, tort, equity or otherwise, and agree that any dispute with respect to any such matters shall be heard only in the courts described above (except that Agent and Lenders shall have the right to bring any action or proceeding against any Borrower or its property in the courts of any other jurisdiction which Agent deems 82

necessary or appropriate in order to realize on the Collateral or to otherwise enforce its rights against any Borrower or its property). (c) Each Borrower hereby waives personal service of any and all process upon it and consents that all such service of process may be made by certified mail (return receipt requested) directed to its address set forth herein and service so made shall be deemed to be completed five (5) days after the same shall have been so deposited in the US mails, or, at Agent's option, by service upon Borrowers in any other manner provided under the rules of any such courts. Within thirty (30) days after such service, Borrowers shall appear in answer to such process, failing which Borrowers shall be deemed in default and judgment may be entered by Lender against Borrowers for the amount of the claim and other relief requested. (d) EACH BORROWER, AGENT, AND EACH LENDER EACH HEREBY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (i) ARISING UNDER THIS AGREEMENT OR ANY OF THE OTHER FINANCING AGREEMENTS OR (ii) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE OTHER FINANCING AGREEMENTS OR THE TRANSACTIONS RELATED HERETO OR THERETO IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE. EACH BORROWER, AGENT, AND EACH LENDER EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT BORROWER OR ANY LENDER MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. (e) Neither Agent nor any Lender shall have any liability to any Borrower (whether in tort, contract, equity or otherwise) for losses suffered by any Borrower in connection with, arising out of, or in any way related to the transactions or relationships contemplated by this Agreement, or any act, omission or event occurring in connection herewith, unless it is determined by a final and non-appealable judgment or court order binding on Agent or such Lender, that the losses were the result of acts or omissions constituting gross negligence or willful misconduct of Agent or such Lender. In any such litigation, Agent and each Lender shall be entitled to the benefit of the rebuttable presumption that it acted in good faith and with the exercise of ordinary care in the performance by it of the terms of this Agreement. Except as prohibited by law, each Borrower waives any right which it may have to claim or recover in any litigation with Agent and any Lender any special, exemplary, punitive or consequential damages or any damages other than, or in addition to, actual damages. Each Borrower: (i) certifies that neither Agent, any Lender nor any representative, agent or attorney acting for or on behalf of Agent or any Lender has represented, expressly or otherwise, that Agent or any Lender would not, in the event of litigation, seek to enforce any of the waivers provided for in this Agreement or any of the other Financing Agreements, and (ii) acknowledges that in entering into this Agreement and the other Financing Agreements, Agent and Lenders are relying upon, among other things, the waivers and certifications set forth in this Section 11.1 and elsewhere herein and therein. 83

11.2 Waiver of Notices. Each Borrower hereby expressly waives demand, presentment, protest and notice of protest and notice of dishonor with respect to any and all instruments and chattel paper, included in or evidencing any of the Obligations or the Collateral, and any and all other demands and notices of any kind or nature whatsoever with respect to the Obligations, the Collateral and this Agreement, except such as are expressly provided for herein. No notice to or demand on any Borrower which Agent or any Lender may elect to give shall entitle any Borrower to any other or further notice or demand in the same, similar or other circumstances. 11.3 Amendments and Waivers. Neither this Agreement nor any provision hereof shall be amended, modified, waived or discharged orally or by course of conduct, but only by a written agreement signed by authorized officers of Agent and Majority Lenders, and as to amendments, as also signed by an authorized officer of Borrowers; provided, that, no amendment, waiver or consent shall be effective, unless (i) in writing and signed by each Lender, to do any of the following: (a) increase or decrease the Maximum Credit, the US Maximum Credit or Canadian Maximum Credit or any Lender's Revolving Loan Limit or Pro Rata Share; (b) reduce the principal of, or interest on, any amount payable hereunder, other than those payable only to Congress in its capacity as Agent which may be reduced by Congress unilaterally; (c) decrease any interest rate or fees payable hereunder to Lenders; (d) postpone any date fixed for any payment of principal of, or interest on, any amounts payable hereunder, other than those payable only to Congress in its capacity as Agent, which may be postponed by Congress unilaterally; (e) increase any advance percentage contained in the definition of the term US Borrowing Base or Canadian Borrowing Base; (f) reduce the number of Lenders that shall be required for Lenders or any of them to take any action hereunder; (g) release or discharge any Person liable for the performance of any obligations of Borrowers hereunder or under any of the Financing Agreements; (h) amend any provision of this Agreement that requires the consent of all Lenders to consent to or waive any breach thereof; (i) amend the definition of the term "Majority Lenders"; (j) amend Section 2.1(d) or (e) or this Section 11.3; (k) release any substantial portion of the Collateral, unless otherwise permitted pursuant to the terms of this Agreement; or 84

(i) in writing and signed by the Agent and financial institution issuing the Letter of Credit Accommodations, to amend any provision of this Agreement or any other Financing Agreement affecting Letter of Credit Accommodations; or (ii) in writing and signed by Agent, in addition to the Lenders if required above, to affect the rights or duties of Agent under this Agreement, or any other Financing Agreement. Agent and Lenders shall not, by any act, delay, omission or otherwise be deemed to have expressly or impliedly waived any of their rights, powers and/or remedies unless such waiver shall be in writing and signed by an authorized officer of Agent and the requisite Lenders. Any such waiver shall be enforceable only to the extent specifically set forth therein. A waiver by Agent and/or Lenders of any right, power and/or remedy on any one occasion shall not be construed as a bar to or waiver of any such right, power and/or remedy which Agent and Lenders would otherwise have on any future occasion, whether similar in kind or otherwise. 11.4 Waiver of Counterclaims. Each Borrower waives all rights to interpose any claims, deductions, setoffs or counterclaims of any nature (other then compulsory counterclaims) in any action or proceeding with respect to this Agreement, the Obligations, the Collateral or any matter arising therefrom or relating hereto or thereto. 11.5 Indemnification. Each Borrower shall indemnify and hold Agent and each Lender, and their respective directors, agents, employees and counsel, harmless from and against any and all losses, claims, damages, liabilities, costs or expenses imposed on, incurred by or asserted against any of them in connection with any litigation, investigation, claim or proceeding commenced or threatened related to the negotiation, preparation, execution, delivery, enforcement, performance or administration of this Agreement, any other Financing Agreements, or any undertaking or proceeding related to any of the transactions contemplated hereby or any act, omission, event or transaction related or attendant thereto, including amounts paid in settlement, court costs, and the fees and expenses of counsel. To the extent that the undertaking to indemnify, pay and hold harmless set forth in this Section 11.5 may be unenforceable because it violates any law or public policy, each Borrower shall pay the maximum portion which it is permitted to pay under applicable law to Agent and Lenders in satisfaction of indemnified matters under this Section 11.5. The foregoing indemnity shall survive the payment of the Obligations and the termination or non-renewal of this Agreement. 11.6 Currency Indemnity. If, for the purposes of obtaining judgment in any court in any jurisdiction with respect to this Agreement or any of the other Financing Agreements, it becomes necessary to convert into the currency of such jurisdiction (the "Judgment Currency") any amount due under this Agreement or under any of the other Financing Agreements in any currency other than the Judgment Currency (the "Currency Due"), then conversion shall be made at the rate of exchange prevailing on the Business Day before the day on which judgment is given. For this purpose, "rate of exchange" means the rate at which Agent is able, on the relevant date, to purchase the Currency Due with the Judgment Currency in accordance with its normal practice. In the event that there is a change in the rate of exchange prevailing between the Business Day before the day on which the judgment is given and the date of receipt by Agent of the amount due, Borrowers will, on the date of receipt by Agent, pay such additional amounts, 85

if any, or be entitled to receive reimbursement of such amount, if any, as may be necessary to ensure that the amount received by Agent and Lenders on such date is the amount in the Judgment Currency which when converted at the rate of exchange prevailing on the date of receipt by Agent is the amount then due under this Agreement or such other of the Financing Agreements in the Currency Due. If the amount of the Currency Due which Agent is able to purchase is less than the amount of the Currency Due originally due to it, Borrowers shall indemnify and save Agent and Lenders harmless from and against loss or damage arising as a result of such deficiency. The indemnity contained herein shall constitute an obligation separate and independent from the other obligations contained in this Agreement and the other Financing Agreements, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by Agent from time to time and shall continue in full force and effect notwithstanding any judgment or order for a liquidated sum in respect of an amount due under this Agreement or any of the other Financing Agreements or under any judgment or order. SECTION 12. TERM OF AGREEMENT; MISCELLANEOUS 12.1 Term. (a) This Agreement and the other Financing Agreements shall become effective as of the date set forth on the first page hereof and shall continue in full force and effect for a term ending on the date three (3) years from the date hereof (the "Termination Date"); provided, that, this Agreement and all other Financing Agreements must be terminated simultaneously. In addition, Borrowers may terminate this Agreement at any time upon ten (10) days prior written notice to Agent (which notice shall be irrevocable) and Agent and Majority Lenders may terminate this Agreement at any time on or after an Event of Default. Upon the effective date of termination or non-renewal of this Agreement, Borrowers shall pay to Agent for the benefit of Lenders, in full, all outstanding and unpaid Obligations and shall furnish cash collateral to Agent (or at Agent's option, a letter of credit issued for the account of Borrowers and at Borrowers' expense, in form and substance satisfactory to Agent, by an issuer acceptable to Lender and payable to Lender as beneficiary) in such amounts as Agent determines are reasonably necessary to secure (or reimburse) Agent and Lenders from loss, cost, damage or expense, including attorneys' fees and legal expenses, in connection with any contingent Obligations, including issued and outstanding Letter of Credit Accommodations and checks or other payments provisionally credited to the Obligations and/or as to which Lender has not yet received final and indefeasible payment. Such payments in respect of the Obligations and cash collateral shall be remitted by wire transfer in Federal funds to such bank account of Agent, as Agent may, in its discretion, designate in writing to Borrowers for such purpose. Interest shall be due until and including the next business day, if the amounts so paid by Borrowers to the bank account designated by Agent are received in such bank account later than 12:00 noon, Boston, Massachusetts time. (b) No termination of this Agreement or the other Financing Agreements shall relieve or discharge Borrowers of their respective duties, obligations and covenants under this Agreement or the other Financing Agreements until all Obligations have been fully and finally discharged and paid, and Agent's continuing security interest in the Collateral and the rights and remedies of Agent and Lenders hereunder, under the other Financing Agreements and applicable law, shall remain in effect until all such Obligations have been fully and finally discharged and paid. Accordingly, each Borrower waives any rights which it may have under the UCC or the 86

PPSA to demand the filing of termination statements with respect to the Collateral, and Agent shall not be required to send such termination statements to Borrowers, or to file them with any filing office, unless and until this Agreement is terminated in accordance with its terms and all of the Obligations are paid and satisfied in full in immediately available funds. (c) If for any reason this Agreement is terminated prior to the end of the term of this Agreement, in view of the impracticality and extreme difficulty of ascertaining actual damages and by mutual agreement of the parties as to a reasonable calculation of Lenders' lost profits as a result thereof and the Lenders' agreement to defer the payment of fees that would otherwise be charged for a financing of this kind, Borrowers agree to pay to Agent for the ratable benefit of Lenders, upon the effective date of such termination, an early termination fee in the amount set forth below if such termination is effective in the period indicated: Amount Period (i) two (2%) percent of the From the date hereof to and Maximum Credit including the first anniversary of the date hereof; (ii) one (1%) percent of the From the day after the first Maximum Credit anniversary of the date hereof to and including the second anniversary of the date hereof; and (iii) one half of one (.50%) From the day after the second percent of the Maximum anniversary of the date hereof to Credit and including the third anniversary of the date of this Agreement. Such early termination fee shall be presumed to be the amount of damages sustained by Lenders as a result of such early termination and Borrowers agree that it is reasonable under the circumstances currently existing. In addition, Lenders shall be entitled to such early termination fee upon the occurrence of any Event of Default described in Sections 10.1(g) and 10.1(h) hereof, even if Agent and Majority Lenders do not exercise the right to terminate this Agreement, but elect, at their sole option, to provide financing to Borrowers or permit the use of cash collateral under the United States Bankruptcy Code. The early termination fee provided for in this Section 12.1 shall be deemed included in the Obligations. 12.2 Interpretative Provisions. (a) All terms used herein which are defined in Article 1 or Article 9 of the UCC shall have the meanings given therein unless otherwise defined in this Agreement. (b) All references to the plural herein shall also mean the singular and to the singular shall also mean the plural unless the context otherwise requires.

(e) The word "including" when used in this Agreement shall mean "including, without limitation". (f) All references to the term "good faith" used herein when applicable to Agent or Lenders shall mean, notwithstanding anything to the contrary contained herein or in the UCC, honesty in fact in the conduct or transaction concerned. Borrower shall have the burden of proving any lack of good faith on the part of Agent or Lenders alleged by Borrower at any time. (g) An Event of Default shall exist or continue or be continuing until such Event of Default is waived in accordance with Section 11.3 or is cured in a manner satisfactory to Agent and Majority Lenders, if such Event of Default is capable of being cured as determined by Agent and Majority Lenders. (h) Any accounting term used in this Agreement shall have, unless otherwise specifically provided herein, the meaning customarily given in accordance with GAAP, and all financial computations hereunder shall be computed unless otherwise specifically provided herein, in accordance with GAAP as consistently applied and using the same method for inventory valuation as used in the preparation of the financial statements of Borrower most recently received by Agent and Lenders prior to the date hereof. (i) In the computation of periods of time from a specified date to a later specified date, the word "from" means "from and including", the words "to" and "until" each mean "to but excluding" and the word "through" means "to and including". (j) Unless otherwise expressly provided herein, (i) references herein to any agreement, document or instrument shall be deemed to include all subsequent amendments, modifications, supplements, extensions, renewals, restatements or replacements with respect thereto, but only to the extent the same are not prohibited by the terms hereof or of any other Financing Agreement, and (ii) references to any statute or regulation are to be construed as including all statutory and regulatory provisions consolidating, amending, replacing, recodifying, supplementing or interpreting the statute or regulation. (k) The captions and headings of this Agreement are for convenience of reference only and shall not affect the interpretation of this Agreement. (l) This Agreement and other Financing Agreements may use several different limitations, tests or measurements to regulate the same or similar matters.

(m) This Agreement and the other Financing Agreements are the result of negotiations among and have been reviewed by counsel to Lender and the other parties, and are the products of all parties. Accordingly, this Agreement and the other Financing Agreements shall not be construed against Agent and Lenders merely because of Agent's involvement in their preparation. 88

The entries in the Register shall be conclusive, in the absence of manifest error, and Borrowers, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement.

(S)341. No such pledge or the enforcement thereof shall release the pledgor Lender from its obligations hereunder or under any of the other Financing Agreements. 12.12 Confidentiality. (a) Agent and Lenders shall use all reasonable efforts to keep confidential, in accordance with its customary procedures for handling confidential information and safe and sound lending practices, any non-public information supplied to it by Borrowers pursuant to this Agreement which is clearly and conspicuously marked as confidential at the time such information is furnished by Borrowers to Agent and Lenders, provided, that, nothing contained herein shall limit the disclosure of any such information: (i) to the extent required by statute, rule, regulation, subpoena or court order, (ii) to bank examiners and other regulators, auditors and/or accountants, (iii) in connection with any litigation to which Agent or any such Lender is a party, (iv) to any assignee or participant (or prospective assignee or participant) so long as such assignee or participant (or prospective assignee or participant) shall have first agreed in writing 92

to treat such information as confidential in accordance with this Section 12.12, or (v) to counsel for Agent or any Lender or any participant or assignee (or prospective participant or assignee). (b) In no event shall this Section 12.12 or any other provision of this Agreement or applicable law be deemed: (i) to apply to or restrict disclosure of information that has been or is made public by any Borrower or any third party without breach of this Section 12.12 or otherwise become generally available to the public other than as a result of a disclosure in violation hereof, (ii) to apply to or restrict disclosure of information that was or becomes available to Agent or any Lender on a non-confidential basis from a person other than a Borrower, (iii) require Agent or any Lender to return any materials furnished by Borrowers to Agent or any Lenders, or (iv) prevent Agent and Lenders from responding to routine informational requests in accordance with the Code of Ethics for the Exchange of Credit Information promulgated by The Robert Morris Associates or other applicable industry standards relating to the exchange of credit information. The obligations of Agent and Lenders under this Section 12.12 shall supersede and replace the obligations of Agent and Lenders under any confidentiality letter signed prior to the date hereof 12.13 Entire Agreement. This Agreement, the other Financing Agreements, any supplements hereto or thereto, and any instruments or documents delivered or to be delivered in connection herewith or therewith represents the entire agreement and understanding concerning the subject matter hereof and thereof between the parties hereto, and supersede all other prior agreements, understandings, negotiations and discussions, representations, warranties, commitments, proposals, offers and contracts concerning the subject matter hereof, whether oral or written. In the event of any inconsistency between the terms of this Agreement and any schedule or exhibit hereto, the terms of this Agreement shall govern. 12.14 Counterparts, Etc. This Agreement or any of the other Financing Agreements may be executed in any number of counterparts, each of which shall be an original, but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of this Agreement or any of the other Financing Agreements by telefacsimile shall have the same force and effect as the delivery of an original executed counterpart of this Agreement or any of such other Financing Agreements. Any party delivering an executed counterpart of any such agreement by telefacsimile shall also deliver an original executed counterpart, but the failure to do so shall not affect the validity, enforceability or binding effect of such agreement. 12.15 Choice of Language. The parties hereto confirm that they have requested that this Agreement and all documents related hereto be drafted in English. Les parties aux presentes ont exige que cette convention ainsi que tout document connexe soient rediges en anglais. SECTION 13. THE AGENT. 13.1 Authorization. (a) The Agent is authorized to take such action on behalf of each of the Lenders and to exercise all such powers as are hereunder and under any of the other Financing Agreements and any related documents delegated to the Agent, together with such powers as are reasonably incident thereto, including the authority, without the necessity of any notice to or further consent of the Lenders, from time to time to take any action with respect to any Collateral 93

or the Financing Agreements which may be necessary to perfect, maintain perfected or insure the priority of the security interest in and liens upon the Collateral granted pursuant hereto or to the other Financing Agreements, and, provided that no duties or responsibilities not expressly assumed herein or therein shall be implied to have been assumed by the Agent. (b) The relationship between the Agent and each of the Lenders is that of an independent contractor. The use of the term "Agent" is for convenience only and is used to describe, as a form of convention, the independent contractual relationship between the Agent and each of the Lenders. Nothing contained in this Agreement nor the other Financing Agreements shall be construed to create an agency, trust or other fiduciary relationship between the Agent and any of the Lenders. (c) As an independent contractor empowered by the Lenders to exercise certain rights and perform certain duties and responsibilities hereunder and under the other Financing Agreements, the Agent is nevertheless a "representative" of the Lenders, as that term is defined in Article 1 of the Uniform Commercial Code, for purposes of actions for the benefit of the Lenders and the Agent with respect to all collateral security and guaranties contemplated by the Financing Agreements. Such actions include the designation of the Agent as "secured party", "mortgagee" or the like on all financing statements and other documents and instruments, whether recorded or otherwise, relating to the attachment, perfection, priority or enforcement of any security interests, mortgages or deeds of trust in collateral security intended to secure the payment or performance of any of the Obligations, all for the benefit of the Lenders and the Agent. 13.2 Employees and Agents. The Agent may exercise its powers and execute its duties by or through employees or agents and shall be entitled to take, and to rely on, advice of counsel concerning all matters pertaining to its rights and duties under this Agreement and the other Financing Agreements. The Agent may utilize the services of such Persons as the Agent in its sole discretion may determine, and all reasonable fees and expenses of any such Persons shall be paid by the Borrower. 13.3 No Liability. Neither the Agent nor any of its shareholders, directors, officers or employees nor any other Person assisting them in their duties nor any agent or employee thereof, shall be liable for any waiver, consent or approval given or any action taken, or omitted to be taken, in good faith by it or them hereunder or under any of the other Financing Agreements, or in connection herewith or therewith, or be responsible for the consequences of any oversight or error of judgment whatsoever, unless it is determined by a final and non-appealable judgment or court order binding on Agent, that the acts or omissions of such Agent or such other Person constituted willful misconduct or gross negligence. 13.4 No Representations. (a) The Agent shall not be responsible for the execution or validity or enforceability of this Agreement, the Letter of Credit Accommodations, any of the other Financing Agreements or any instrument at any time constituting, or intended to constitute, collateral security for any of the Financing Agreements, or for the value of any such collateral security or for the validity, enforceability, or collectability of any such amounts owing with respect to any of the Financing Agreements, or for any recitals or statements, warranties or representations made herein or in any of the other Financing Agreements or in any certificate or 94

instrument hereafter furnished to it by or on behalf of Borrowers or any of their Subsidiaries, or be bound to ascertain or inquire as to the performance or observance of any of the terms, conditions, covenants or agreements herein or in any instrument at any time constituting, or intended to constitute, collateral security for any of the Financing Agreements or to inspect any of the properties, books or records of Borrowers or any of their Subsidiaries. The Agent shall not be bound to ascertain whether any notice, consent, waiver or request delivered to it by Borrowers shall have been duly authorized or is true, accurate and complete. The Agent has not made nor does it now make any representations or warranties, express or implied, nor does it assume any liability to the Lenders, with respect to the credit worthiness or financial conditions of Borrowers or any of its Subsidiaries. Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender, and based upon such information and documents as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. (b) For purposes of determining compliance with the conditions set forth in Section 4, each Lender that has executed this Agreement shall be deemed to have consented to, approved or accepted, or to be satisfied with, each document and matter either sent, or made available, by the Agent to such Lender for consent, approval, acceptance or satisfaction, or required thereunder to be to be consent to or approved by or acceptable or satisfactory to such Lender, unless an officer of the Agent active upon the Borrower's account shall have received notice from such Lender not less than one (1) Business Day prior to the date of the closing hereunder specifying such Lender's objection thereto and such objection shall not have been withdrawn by notice to the Agent to such effect on or prior to such date. 13.5 Payments. (a) A payment by Borrowers to the Agent hereunder or under any of the other Financing Agreements for the account of any Lender shall constitute a payment to such Lender. The Agent agrees promptly to distribute to each Lender such Lender's pro rata share of payments received by the Agent for the account of the Lenders except as otherwise expressly provided herein or in any of the other Financing Agreements. (b) If in the opinion of the Agent the distribution of any amount received by it in such capacity hereunder or under any of the other Financing Agreements might involve it in liability, it may refrain from making distribution until its right to make distribution shall have been adjudicated by a court of competent jurisdiction. If a court of competent jurisdiction shall adjudge that any amount received and distributed by the Agent is to be repaid, each Person to whom any such distribution shall have been made shall either repay to the Agent its proportionate share of the amount so adjudged to be repaid or shall pay over the same in such manner and to such Persons as shall be determined by such court. (c) Notwithstanding anything to the contrary contained in this Agreement or any of the other Financing Agreements, any Lender that fails (i) to make available to the Agent its pro rata share of any Loan or to purchase any participation in a Letter of Credit Accommodation, or (ii) to comply with the provisions of Section 10.2(i) with respect to making dispositions and arrangements with the other Lenders, where such Lender's share of any payment received, whether by setoff or otherwise, is in excess of its pro rata share of such payments due and payable to all of the Lenders, in each case as, when and to the full extent required by the 95

provisions of this Agreement, shall be deemed delinquent (a "Delinquent Lender") and shall be deemed a Delinquent Lender until such time as such delinquency is satisfied. A Delinquent Lender shall be deemed to have assigned any and all payments due to it from Borrowers and other Obligors, whether on account of outstanding Revolving Loans, Term Loans, interest, fees or otherwise, to the remaining non-delinquent Lenders for application to, and reduction of, their respective pro rata shares of all outstanding Revolving Loans and other Obligations. The Delinquent Lender hereby authorizes the Agent to distribute such payments to the non-delinquent Lenders in proportion to their respective pro rata shares of all outstanding Revolving Loans and other Obligations. A Delinquent Lender shall be deemed to have satisfied in full a delinquency when and if, as a result of application of the assigned payments to all outstanding Revolving Loans and other Obligations of the non-delinquent Lenders, the Lenders' respective pro rata shares of all outstanding Revolving Loans and other Obligations have returned to those in effect immediately prior to such delinquency and without giving effect to the nonpayment causing such delinquency. (d) At the Borrowers' request, the Agent or an Eligible Assignee reasonably acceptable to the Agent shall have the right (but not the obligation) to purchase from any Delinquent Lender, and each Delinquent Lender shall, upon such request, sell and assign to the Agent or such Eligible Assignee, all of the Delinquent Lender's outstanding Revolving Loans and participations in Letter of Credit Accommodations hereunder. Such sale shall be consummated promptly after the Agent has arranged for a purchase by the Agent or an Eligible Assignee pursuant to an Assignment and Acceptance, and at a price equal to the outstanding principal balance of the Delinquent Lender's Revolving Loans plus accrued interest and fees, without premium or discount. 13.6 Holders of Letter of Credit Accommodation Participations. The Agent may deem and treat the purchaser of any participation in Letter of Credit Accommodations as the absolute owner or purchaser thereof for all purposes hereof until it shall have been furnished in writing with a different name by such payee or by a subsequent holder, assignee or transferee. 13.7 Indemnity. The Lenders ratably agree hereby to indemnify and hold harmless the Agent and the Reference Bank from and against any and all claims, actions and suits (whether groundless or otherwise), losses, damages, costs, expenses (including any expenses for which the Agent and/or the Reference Bank has not been reimbursed by the Borrowers as required by Section 11.5), and liabilities of every nature and character arising out of or related to this Agreement or any of the other Financing Agreements or the transactions contemplated or evidenced hereby or thereby, or the Agent's or the Reference Bank's actions taken hereunder or thereunder, unless it is determined by a court of competent jurisdiction by a final and non-appealable judgment or court order binding on Agent or Reference Bank, as the case may be, that such loss was the result of acts or omissions of the Agent or the Reference Bank, as the case may be, constituting willful misconduct or gross negligence. 13.8 Agent as Lender. In its individual capacity, Congress shall have the same obligations and the same rights, powers and privileges in respect to the Loans made by it and as the purchaser of a participation in any Letter of Credit Accommodation, as it would have were it not also the Agent. 96

13.9 Resignation; Removal. The Agent may resign at any time by giving sixty (60) days prior written notice thereof to the Lenders and Borrowers. Upon any such resignation, the Majority Lenders shall have the right to appoint a successor Agent. Unless a Default or Event of Default shall have occurred and be continuing, such successor Agent shall be reasonably acceptable to the Borrowers. If no successor Agent shall have been so appointed by the Majority Lenders and shall have accepted such appointment within thirty (30) days after the retiring Agent's giving of notice of resignation, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a financial institution having a rating of not less than A or its equivalent by Standard & Poor's Corporation. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. After any retiring Agent's resignation, the provisions of this Agreement and the other Financing Agreements shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Agent. 13.10 Notification of Defaults and Events of Default. Agent shall not be deemed to have notice of a Default or an Event of Default unless it is notified thereof by a Borrower or a Lender with reference to this Agreement. Each Lender hereby agrees that, upon learning of the existence of a Default or Event of Default, it shall promptly notify the Agent thereof. The Agent hereby agrees that upon receipt of any notice under this Section 13.10 it shall promptly notify the other Lenders of the existence of such Default or Event of Default. 13.11 Duties in the Case of Enforcement. Each Lender agrees that, except as set forth in Section 10.1(h), no Lender shall have the right individually (i) to realize upon the security created under this Agreement or the other Financing Agreements, (ii) to enforce any provision of this Agreement or the other Financing Agreements or to exercise any remedy hereunder or thereunder, or (iii) to make demand under this Agreement or any other Financing Agreement. In case one or more Events of Default have occurred and shall be continuing, and whether or not acceleration of the Obligations shall have occurred, the Agent shall, if (a) so requested by the Majority Lenders and (b) the Lenders have provided to the Agent such additional indemnities and assurances against expenses and liabilities as the Agent may reasonably request, proceed to enforce the provisions hereof, the Financing Agreements authorizing the sale or other disposition of all or any part of the Collateral, and exercise all or any such other legal and equitable and other rights or remedies as it may have in respect of such Collateral. The Majority Lenders may direct the Agent in writing as to the method and the extent of any such sale or other disposition, the Lenders hereby agreeing to indemnify and hold the Agent, harmless from all liabilities incurred in respect of all actions taken or omitted in accordance with such directions, provided that the Agent need not comply with any such direction to the extent that the Agent reasonably believes the Agent's compliance with such direction to be unlawful or commercially unreasonable in any applicable jurisdiction. 13.12 Agency for Perfection. Each Lender hereby appoints each other Lender as agent for the purpose of perfecting the Lenders' security interest in assets which, in accordance with Article 9 of the UCC can be perfected only by possession. Should any Lender (other than the Agent) obtain possession of any such Collateral, such Lender shall notify the Agent thereof, and, promptly upon the Agent's request therefore shall deliver such Collateral to the Agent or in accordance with the Agent's instructions. 97

13.13 Field Audit and Examination Reports; Disclaimer by Lenders. In the event that the Agent provides to Lenders copies of field audits or examination reports (each a "Report" and collectively, "Reports"), in Agent's discretion, each Lender: (a) expressly agrees and acknowledges that the Agent (i) makes no representation or warranty as to the accuracy of any Report; or (ii) shall be liable for any information contained in any Report; (b) expressly agrees and acknowledges that the Reports are not comprehensive audits or examinations, that the Agent or other party performing any audit or examination will inspect only specific information regarding the Borrowers and will rely significantly upon each Borrowers' books and records, as well as on representations of each Borrower's personnel; (c) agrees to keep all Reports confidential and strictly for its internal use, and not to distribute except to its participants, or use any Report in any other manner; and (d) without limiting the generality of any other indemnification provision contained in this Agreement, agrees: (i) to hold the Agent and any such other Lender preparing a Report harmless from any action the indemnifying Lender may take or conclusion the indemnifying Lender may reach or draw from any Report in connection with any loans or other credit accommodations that the indemnifying Lender has made or may make to any of the Borrowers, or the indemnifying Lender's participation in, or the indemnifying Lender's purchase of, a loan or loans of any of the Borrowers; and (ii) to pay and protect, and indemnify, defend and hold the Agent and any such other Lender preparing a Report harmless from and against, the claims, actions, proceedings, damages, costs, expenses and other amounts (including attorney's fees and expenses) incurred by the Agent and any such other Lender preparing a Report as the direct or indirect result of any third parties who might obtain all or part of any Report through the indemnifying Lender. 13.14 Agent as fonde de pouvoir. Without prejudice to the provisions of this Agreement, each Lender hereby designates and appoints the Agent as the person holding the power of attorney (fonde de pouvoir) of the Lenders as contemplated under Article 2692 of the Civil Code of Quebec, to enter into, to take and to hold on their behalf, and for their benefit, the Deed of Hypothec, and to exercise such powers and duties which are conferred upon the Agent under the Deed of Hypothec. Any Person who becomes a Lender shall be deemed to have consented to and confirmed the Agent as the person holding the power of attorney (fonde de pouvoir) as aforesaid and to have ratified, as of the date it becomes a Lender, all actions taken by the Agent in such capacity. As the person holding the power of attorney (fonde de pouvoir), the Agent shall be entitled to delegate from time to time any of its powers or duties under the Deed of Hypothec to any Person and on such terms and conditions as the Agent may determine from time to time. Without prejudice to the designations and appointment of the Agent as the person holding the power of attorney (fonde de pouvoir) as aforesaid, each Lender hereby additionally designates and appoints the Agent as agent and custodian for and on behalf of each of them to hold and to be the sole registered holder of any bond issued under the Deed of Hypothec, notwithstanding Section 32 of An Act respecting the special powers of legal persons (Quebec) or any other requirement of law. In this respect, (i) the Agent, as agent and custodian of the 98

Lenders, shall keep a record indicating the names and addresses of, and the pro rata portion of the obligations and indebtedness secured by the Movable Hypothec, owing to the persons for and on behalf of whom the aforesaid bond is so held from time to time and (ii) each Lender will be entitled to the benefits of any Collateral subject to the Deed of Hypothec and will participate in the proceeds of realization of any such collateral, the whole in accordance with the terms hereof. The Agent, in such capacity as agent and custodian shall, (x) have the sole and exclusive right and authority to exercise, except as may be otherwise specifically restricted by the terms hereof, all rights and remedies given to the Agent with respect to the Collateral under the Deed of Hypothec and Movable Hypothec, applicable law or otherwise, and (y) benefit from and be subject to all provisions hereof with respect to the Agent mutatis mutandis, including, without limitation, all such provisions with respect to the liability or responsibility to and indemnification by the Lenders. Any Person who becomes a Lender shall be deemed to have consented to and confirmed the Agent as the agent and custodian as aforesaid and to have ratified, as of the date it becomes a Lender, all actions taken by the Agent in such capacity. As agent and custodian, the Agent shall be entitled to delegate from time to time any of its powers or duties hereunder to any Person and on such terms and conditions as the Agent may determine from time to time. SECTION 14. JOINT AND SEVERAL LIABILITY; GUARANTEES. 14.1 Joint and Several Liability. All Loans made and Letter of Credit Accommodations issued hereunder are made to or for the mutual benefit, directly and indirectly, of each of the Borrowers and in consideration of the agreement of the other Borrowers to accept joint and several liability for the Obligations. Each Borrower jointly and severally, hereby irrevocably and unconditionally accepts, not merely as a surety but also as a co-debtor, joint and several and direct and primary liability for the full and indefeasible payment when due and performance of all Obligations and for the prompt and full payment and performance of all of the promises, covenants, representations, and warranties made or undertaken by each Borrower under the Financing Agreements and Borrowers agree that such liability is independent of the duties, obligations, and liabilities of each of the joint and several Borrowers. In furtherance of the foregoing, each Borrower jointly and severally, absolutely and unconditionally guarantees to Agent and Lenders the full and indefeasible payment and performance when due of all the Obligations. 14.2 Suretyship Waivers and Consents. (a) Each Borrower acknowledges that the obligations of such Borrower undertaken herein might be construed to consist, at least in part, of the guarantee of obligations of persons other than such Borrower (including the other Borrowers) and, in full recognition of that fact and in full recognition of the joint and several and direct and primary liability of each Borrower hereunder, each Borrower consents and agrees that Agent and Lenders may, at any time and from time to time, without notice or demand (except as provided in and in accordance with the terms of this Agreement), whether before or after any actual or purported termination, repudiation or revocation of this Agreement by any Borrower, and without affecting the enforceability or continuing effectiveness hereof as to each Borrower: (i) increase, extend, or otherwise change the time for payment or the terms of the Obligations or any part thereof; (ii) supplement, restate, modify, amend, increase, decrease, or waive, or enter into or give any agreement, approval or consent with respect to, the Obligations or any part thereof, or any of the Financing Agreements or any additional security or guarantees, or any condition, covenant, 99

default, remedy, right, representation, or term thereof or thereunder; (iii) accept new or additional instruments, documents, or agreements in exchange for or relative to any of the Financing Agreements or the Obligations or any part thereof; (iv) accept partial payments on the Obligations; (v) receive and hold additional security or guarantees for the Obligations or any part thereof; (vi) release, reconvey, terminate, waive, abandon, fail to perfect, subordinate, exchange, substitute, transfer, or enforce any security or guarantees, and apply any security and direct the order or manner of sale thereof as Agent in its sole and absolute discretion may determine; (vii) release any person from any personal liability with respect to the Obligations or any part thereof; (viii) settle, release on terms satisfactory to Agent or by operation of applicable laws or otherwise liquidate or enforce any Obligations and any security therefor or guaranty thereof in any manner, consent to the transfer of any security and bid and purchase at any sale; or (ix) consent to the merger, change, or any other restructuring or termination of the corporate or partnership existence of any Borrower, and correspondingly restructure the Obligations, and any such merger, change, restructuring, or termination shall not affect the liability of any Borrower or the continuing effectiveness hereof, or the enforceability hereof with respect to all or any part of the Obligations. (b) Agent and Lenders may enforce this Agreement independently as to each Borrower and independently of any other remedy or security Agent and Lenders at any time may have or hold in connection with the Obligations, and it shall not be necessary for Agent and Lenders to marshal assets in favor of any Borrower or any Obligor or to proceed upon or against or exhaust any security or remedy before proceeding to enforce this Agreement. Each Borrower expressly waives any right to require Agent to marshal assets in favor of any Borrower or any guarantor of the Obligations or to proceed against any other Borrower, and agrees that Agent may proceed against Borrowers or any Collateral in such order as Agent shall determine in its sole and absolute discretion. (c) Agent and Lenders may file a separate action or actions against any Borrower, whether such action is brought or prosecuted with respect to any security or against any guarantor of the Obligations, or whether any other person is joined in any such action or actions. Each Borrower agrees that Agent and Lenders and each Borrower and any affiliate of any Borrower may deal with each other in connection with the Obligations or otherwise, or alter any contracts or agreements now or hereafter existing between any of them, in any manner whatsoever, all without in any way altering or affecting the continuing efficacy of this Agreement. Each Borrower, as a joint and several Borrower and guarantor hereunder, expressly waives the benefit of any statute of limitations affecting its joint and several liability and guarantee hereunder (but not its primary liability) or the enforcement of the Obligations or any rights of Agent and Lender created or granted herein. (d) Agent's and Lender's rights hereunder shall be reinstated and revived, and the enforceability of this Agreement shall continue, with respect to any amount at any time paid on account of the Obligations which thereafter shall be required to be restored or returned by Agent and Lenders, all as though such amount had not been paid. The rights of Agent and Lenders created or granted herein and the enforceability of this Agreement at all times shall remain effective to cover the full amount of all the Obligations even though the Obligations, including any part thereof or any other security or guaranty therefor, may be or hereafter may become invalid or otherwise unenforceable as against any Borrower and whether or not any Borrower shall have any personal liability with respect thereto. 100

(e) Each Borrower expressly waives any and all defenses now or hereafter arising or asserted by reason of (i) any disability or other defense of the other Borrowers with respect to the Obligations; (ii) the unenforceability or invalidity of any security or guaranty for the Obligations or the lack of perfection or continuing perfection or failure of priority of any security for the Obligations; (iii) the cessation for any cause whatsoever of the liability of any Borrower (other than by reason of the full payment and performance of all Obligations); (iv) any failure of Lender to marshal assets in favor of any Borrower; (v) any failure of Agent or Lenders to give notice to any Borrower of sale or other disposition of Collateral of another Borrower or any defect in any notice that may be given in connection with any such sale or disposition of Collateral of any Borrower securing the Obligations; (vi) any failure of Agent or Lenders to comply with applicable law in connection with the sale or other disposition of any Collateral or other security of any Borrower, for any Obligation, including any failure of Agent or Lenders to conduct a commercially reasonable sale or other disposition of any Collateral or other security of the other Borrowers for any Obligation; (vii) any act or omission of Agent or Lenders or others that directly or indirectly results in or aids the discharge or release of the other Borrowers or the Obligations of the other Borrowers or any security or guaranty therefor by operation of law or otherwise; (viii) any law which provides that the obligation of a surety or guarantor must neither be larger in amount nor in other respects more burdensome than that of the principal or which reduces a surety's or guarantor's obligation in proportion to the principal obligation; (ix) any failure of Agent or Lenders to file or enforce a claim in any bankruptcy or other proceeding with respect to any Borrower; (x) the avoidance of any lien or security interest in assets of the other Borrowers in favor of Agent or Lenders for any reason; or (xi) any action taken by Agent or Lenders that is authorized by this section or any other provision of any Loan Document. Until such time, if any, as all of the Obligations have been indefeasibly paid and performed in full and no portion of any commitment of Agent or Lenders to Borrowers under any Financing Agreement remains in effect, Borrowers' rights of subrogation, contribution, reimbursement, or indemnity against the other shall be fully and completely subordinated to the indefeasible repayment in full of the Obligations, and each Borrower expressly waives any right to enforce any remedy that it now has or hereafter may have against any other Person and waives the benefit of, or any right to participate in, any Collateral now or hereafter held by Agent or Lenders. (f) To the fullest extent permitted by applicable law, each Borrower expressly waives and agrees not to assert, any and all defenses in its favor based upon an election of remedies by Agent or Lenders which destroys, diminishes, or affects such Borrower's subrogation rights against the other Borrowers, or against any Obligor, and/or (except as explicitly provided for herein) any rights to proceed against each other Borrower, or any other party liable to Agent or Lenders, for reimbursement, contribution, indemnity, or otherwise. (g) Borrowers and each of them warrant and agree that each of the waivers and consents set forth herein are made after consultation with legal counsel and with full knowledge of their significance and consequences, with the understanding that events giving rise to any defense or right waived may diminish, destroy, or otherwise adversely affect rights which Borrowers otherwise may have against each other, Agent or Lenders, or others, or against Collateral, and that, under the circumstances, the waivers and consents herein given are reasonable and not contrary to public policy or law. If any of the waivers or consents herein are determined to be contrary to any applicable law or public policy, such waivers and consents shall be effective to the maximum extent permitted by law. 101

(h) Notwithstanding any provision herein to the contrary, the joint and several liability and guarantees of the Canadian Borrowers shall be limited to the maximum amount permitted under any laws to which a Canadian Borrower is subject. 14.3 Contribution Agreement. As an inducement to Agent and Lenders to enter into the Financing Agreements and to make the loans and extend credit to the Borrowers, each Borrower and each Obligor agrees to indemnify and hold the other harmless from and each shall have a continuing right of contribution against the other Borrowers and any Obligors, if and to the extent that a Borrower makes or is caused to make disproportionate payments in excess of that Borrower's Proportionate Share of the Loans or contributions (from dispositions of its assets or otherwise) to the repayment and satisfaction of the Obligations. These indemnification and contribution obligations shall be unconditional and continuing obligations of the Borrowers and Obligors and shall not be waived, rescinded, modified, limited or terminated in any way whatsoever without the prior written consent of Agent, in its sole discretion. For purposes hereof, the "Proportionate Share" of a Borrower shall mean the Adjusted Net Worth of such Borrower divided by the Adjusted Net Worth of all the Borrowers in the aggregate on the date of this Agreement. 14.4 PREJUDGMENT REMEDIES. EACH BORROWER HEREBY WAIVES SUCH RIGHTS AS IT MAY HAVE TO NOTICE AND/OR HEARING UNDER ANY APPLICABLE FEDERAL OR STATE LAWS INCLUDING, WITHOUT LIMITATION, CONNECTICUT GENERAL STATUTES SECTIONS 52-278A, ET-SEQ., AS AMENDED, PERTAINING TO THE EXERCISE BY AGENT OR LENDERS OF SUCH RIGHTS AS THE AGENT AND LENDERS MAY HAVE INCLUDING, BUT NOT LIMITED TO, THE RIGHT TO SEEK PREJUDGMENT REMEDIES AND/OR DEPRIVE ANY BORROWER OF OR AFFECT THE USE OF OR POSSESSION OR ENJOYMENT OF A BORROWER'S PROPERTY PRIOR TO THE RENDITION OF A FINAL JUDGMENT AGAINST A BORROWER. EACH BORROWER FURTHER WAIVES ANY RIGHT IT MAY HAVE TO REQUIRE AGENT OR LENDERS TO PROVIDE A BOND OR OTHER SECURITY AS A PRECONDITION TO OR IN CONNECTION WITH ANY PREJUDGMENT REMEDY SOUGHT BY LENDER.

The Agent and the Lenders may act without liability upon the basis of written, telecopied or telephonic notice believed by the Agent in good faith to be from the Administrative Borrower (or from any Authorized Officer thereof designated in writing purportedly from the Administrative Borrower to the Agent). Each Borrower hereby waives the right to dispute the Agent's record of the terms of any such telephonic Notice of Borrowing. The Agent and each Lender shall be entitled to rely conclusively on any Authorized Officer's authority to request a Loan on behalf of the Borrowers until the Agent receives written notice to the contrary. The Agent and the Lenders shall have no duty to verify the authenticity of the signature appearing on any written Notice of Borrowing. (b) Each Notice of Borrowing pursuant to this Section 2.02 shall be irrevocable and the Borrowers shall be bound to make a borrowing in accordance therewith. (c) Subject to Section 2.01(c), all Loans under this Agreement shall be made by the Lenders simultaneously and proportionately to their Pro Rata Shares of the Total Term Loan A Commitment and the Total Term Loan B Commitment, as the case may be, it being understood that no Lender shall be responsible for any default by any other Lender in that other Lender's obligations to make a Loan requested hereunder, nor shall the Commitment of any Lender be increased or decreased as a result of the default by any other Lender in that other Lender's obligation to make a Loan requested hereunder, and each Lender shall be obligated to make the Loans required to be made by it by the terms of this Agreement regardless of the failure by any other Lender. Section 2.03 Repayment of Loans; Evidence of Debt. (a) The outstanding principal of the Term Loan A shall be due and payable on the Term A Maturity Date. The outstanding principal of the Term Loan B shall be due and payable on the Term B Maturity Date. (b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the Indebtedness of the Borrowers to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. (c) The Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrowers to each Lender hereunder and (iii) the -27-

amount of any sum received by the Agent hereunder for the account of the Lenders and each Lender's share thereof. (d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrowers to repay the Loans in accordance with the terms of this Agreement. (e) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrowers shall execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) in a form furnished by the Agent and reasonably acceptable to the Administrative Borrower. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 12.07) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns). Section 2.04 Interest. (a) Term Loan A. The Term Loan A shall be a LIBOR Loan, except as otherwise provided in Section 2.09. The portion of the Term Loan A that is a LIBOR Loan shall bear interest on the principal amount thereof from time to time outstanding, from the date of the Term Loan A until such principal amount becomes due, at a rate per annum equal to the LIBOR Rate for the Interest Period in effect for such portion of the Term Loan A plus 7.25%. The portion of the Term Loan A that is a Reference Rate Loan shall bear interest on the principal amount thereof from time to time outstanding, from the date of the Term Loan A until such principal amount becomes due, at a rate per annum equal to the Reference Rate plus 4.50%. (b) Term Loan B. The Term Loan B shall bear interest on the principal amount thereof from time to time outstanding, from the date of the Term Loan B until such principal amount becomes due, at a rate per annum equal to 22%; provided, however, that, so long as no Event of Default has occurred and is continuing, interest on the outstanding principal amount of the Term Loan B at a per annum rate equal to 11% shall, in the absence of an election by the Administrative Borrower to pay such interest in cash, be paid by capitalizing such interest and adding such capitalized interest to the then outstanding principal amount of the Term Loan B. Any interest to be capitalized shall be capitalized on the date such interest is to be paid pursuant to Section 2.04(d) and added to the then outstanding principal amount of the Term Loan B and thereafter shall bear interest as provided hereunder as if it had originally been part of the outstanding principal of the Term Loan B. (c) Default Interest. To the extent permitted by law, upon the occurrence and during the continuance of an Event of Default, the principal of, and all accrued and unpaid interest on, all Loans, fees, indemnities, any other Obligations of the Loan Parties under this Agreement and the other Loan Documents, shall bear interest, from the date such Event of Default occurred until the date such Event of Default is cured or waived in writing in accordance herewith, at a rate per annum equal at all times to the Post-Default Rate. (d) Interest Payment. Interest on each Loan (other than capitalized interest) shall accrue and be payable (in the manner described in Section 4.02) monthly, in -28-

arrears, on the first day of each month, commencing on the first day of the month following the month in which such Loan is made and at maturity (whether upon demand, by acceleration or otherwise). Interest at the Post-Default Rate shall be payable on demand. Each Borrower hereby authorizes the Agent to, and the Agent may, from time to time, charge the Loan Account pursuant to Section 4.02 with the amount of any interest payment due hereunder. (e) General. All interest shall be computed on the basis of a year of 360 days for the actual number of days, including the first day but excluding the last day, elapsed. Section 2.05 Term Loan Commitments; Prepayment of Loans. (a) Commitment Increase. The amount of the Total Term Loan A Commitment and the Total Term Loan B Commitment shall increase solely in accordance with the terms of Section 2.01(c). (b) Optional Prepayment. (i) Term Loan A. The Borrowers may, upon at least five (5) Business Days' prior written notice to the Agent, prepay the principal of the Term Loan A, in whole but not in part. Any prepayment made pursuant to this clause (b)(i) shall be accompanied by the payment of accrued interest to the date of such payment on the amount prepaid together with the payment of the applicable Early Termination Fee. (ii) Term Loan B. The Borrowers may, upon at least five (5) Business Days' prior written notice to the Agent, prepay the principal of the Term Loan B, in whole but not in part. Any prepayment made pursuant to this clause (b)(ii) shall be accompanied by the payment of accrued interest to the date of such payment on the amount prepaid together with the payment of the applicable Early Termination Fee. (c) Mandatory Prepayment. (i) Immediately upon any Disposition by any Loan Party or its Subsidiaries pursuant to Section 7.02(c)(ii), the Borrowers shall prepay the outstanding principal amount of the Term Loan A (or, if the Term Loan A has been paid in full, the Term Loan B) in an amount equal to 100% of the Net Cash Proceeds received by such Person in connection with such Disposition to the extent that the aggregate amount of Net Cash Proceeds received by all Loan Parties and their Subsidiaries (and not paid to the Agent as a prepayment of the Loans) shall exceed, for all such Dispositions since the Effective Date, $500,000. Nothing contained in this subsection (ii) shall permit any Loan Party or any of its Subsidiaries to make a Disposition of any property other than in accordance with Section 7.02(c)(ii). (ii) Upon the issuance or incurrence by any Loan Party or any of its Subsidiaries of any Indebtedness referred to in clause (f) of the definition of "Permitted Indebtedness", or the sale or issuance by any Loan Party or any of its Subsidiaries of any shares of its Capital Stock (other than the issuance or sale of such shares permitted under Section 7.02(l)), the Borrowers shall prepay the outstanding amount of the Term Loan A (or if the Term Loan A has been paid in full, the Term Loan B) in an amount equal to 100% of the Net Cash Proceeds received by such Person in connection therewith. The provisions of this subsection (iii) -29-

shall not be deemed to be implied consent to any such issuance, incurrence or sale otherwise prohibited by the terms and conditions of this Agreement. (iii) Upon the receipt by any Loan Party or any of its Subsidiaries of any Extraordinary Receipts (other than Extraordinary Receipts comprising insurance proceeds) in an aggregate amount greater than $100,000 or Extraordinary Receipts comprising insurance proceeds, in each case since the Effective Date, the Borrowers shall prepay the outstanding principal of the Term Loan A (or, if the Term Loan A has been repaid in full, the Term Loan B) in an amount equal to 100% of such Extraordinary Receipts, net of any reasonable expenses incurred in collecting such Extraordinary Receipts, provided that: (A) in the case of Extraordinary Receipts comprising proceeds of business interruption insurance or foreign, United States, state or local tax refunds, such Extraordinary Receipts shall be applied to prepay the Loans in accordance with this Section 2.05(c)(iii) only in the event a Default or Event of Default has occurred and is continuing on the date such Extraordinary Receipts are received by such Loan Party; and (B) except during the continuance of a Default or Event of Default, Extraordinary Receipts comprising insurance proceeds that are not otherwise subject to clause (A) above shall not be required to be so prepaid on the date such proceeds are received by such Loan Party to the extent (I) such proceeds are used to replace or restore the properties or assets used in such Person's business in respect of which such proceeds were paid if the Administrative Borrower delivers a certificate to the Agent within 30 days of such event stating that such proceeds shall be used to replace or restore any such properties or assets to be used in such Person's business within a period specified in such certificate not to exceed 180 days after the receipt of such proceeds (which certificate shall set forth estimates of the proceeds to be so expended) and (II) such proceeds are deposited in a deposit account subject to a Control Agreement. If all or any portion of such proceeds not so applied to the prepayment of the Term Loans are not so used within the period specified in the relevant certificate furnished pursuant hereto (not to exceed 180 days), such remaining portion shall prepay the outstanding principal of the Loans on the last day of such specified period. In addition, upon the occurrence and during the continuance of an Event of Default, the Agent may apply such proceeds to the prepayment of the Loans. (iv) Upon the occurrence of a Change of Control under paragraph (a) of the definition of the term "Change of Control", the Borrowers shall, upon demand from the Agent, prepay the outstanding principal of the Term Loan A and the Term Loan B. Any prepayment made pursuant to this clause (c)(iv) shall be accompanied by the payment of accrued interest to the date of such payment on the amount prepaid together with the payment of a prepayment fee equal to 1% of the principal amount of the Term Loan B so prepaid, and each Lender holding a Term Loan B shall be entitled to receive its ratable portion of such prepayment fee pursuant to Section 4.02. (d) Application of Payments. Each prepayment pursuant to subsections (c)(i), (c)(ii) and (c)(iii) above shall be applied, first, to the Term Loan A, and second, to the Term Loan B. -30-

(e) Interest and Fees. Any prepayment made pursuant to this Section 2.05 shall be accompanied by accrued interest on the principal amount being prepaid to the date of prepayment, and if such prepayment would reduce the amount of the outstanding Loans to zero, such prepayment shall be accompanied by the payment of all fees accrued to such date pursuant to Section 2.06. (f) Cumulative Prepayments. Except as otherwise expressly provided in this Section 2.05, payments with respect to any subsection of this Section 2.05 are in addition to payments made or required to be made under any other subsection of this Section 2.05. Section 2.06 Fees. (a) Funding Fee. The Borrowers shall pay to the Agent for the account of the Lenders, in accordance with their Pro Rata Shares of any additional Term Loan B made after the Effective Date in accordance with Section 2.01(c)(iv), a non-refundable funding fee (the "Funding Fee") equal to 2% of the aggregate original principal amount of such additional Term Loan B, which shall be deemed fully earned when paid and shall be payable on the date of the making of such additional Term Loan B. Section 2.07 Securitization. The Loan Parties hereby acknowledge that the Lenders and their Affiliates may sell or securitize the Loans (a "Securitization") through the pledge of the Loans as collateral security for loans to the Lenders or their Affiliates or through the sale of the Loans or the issuance of direct or indirect interests in the Loans, which loans to the Lenders or their Affiliates or direct or indirect interests will be rated by Moody's, Standard & Poor's or one or more other rating agencies (the "Rating Agencies"). The Loan Parties shall cooperate with the Lenders and their Affiliates to effect the Securitization including, without limitation, by (a) amending this Agreement and the other Loan Documents, and executing such additional documents, as reasonably requested by the Lenders in connection with the Securitization, provided that (i) any such amendment or additional documentation does not impose material additional costs on the Loan Parties and (ii) any such amendment or additional documentation does not materially adversely affect the rights, or materially increase the obligations, of the Loan Parties under the Loan Documents or change or affect in a manner adverse to the Loan Parties the financial terms of the Loans, (b) providing such information as may be reasonably requested by the Lenders in connection with the rating of the Loans or the Securitization, and (c) providing in connection with any rating of the Loans a certificate (i) agreeing to indemnify the Lenders and their Affiliates, any of the Rating Agencies, or any party providing credit support or otherwise participating in the Securitization (collectively, the "Securitization Parties") for any losses, claims, damages or liabilities (the "Liabilities") to which the Lenders, their Affiliates or such Securitization Parties may become subject insofar as the Liabilities arise out of or are based upon any untrue statement of any material fact contained in any Loan Document or in any writing delivered by or on behalf of any Loan Party to the Lenders in connection with any Loan Document or arise out of or are based upon the omission to state therein a material fact required to be stated therein, or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, and such indemnity shall survive any transfer by the Lenders or their successors or assigns of the Loans and (ii) agreeing to reimburse the Lenders and their Affiliates for any legal or other expenses reasonably incurred by such Persons in connection with defending the Liabilities. Section 2.08 Taxes. (a) All payments made by any Loan Party hereunder or under any other Loan Document shall be made without set-off, counterclaim, deduction or other -31-

defense. All such payments shall be made free and clear of and without deduction for any present or future income, franchise, sales, use, excise, stamp or other taxes, levies, imposts, deductions, charges, fees, withholdings, restrictions or conditions of any nature now or hereafter imposed, levied, collected, withheld or assessed by any jurisdiction (whether pursuant to Federal, state, local or foreign law) or by any political subdivision or taxing authority thereof or therein, and all interest, penalties or additional amounts, excluding taxes on the net income of any Lender or the Agent imposed by the jurisdiction in which such Lender or the Agent is organized or any political subdivision thereof or taxing authority thereof or any jurisdiction in which such Person's principal office is located or any political subdivision thereof or taxing authority thereof (such nonexcluded taxes, levies, imposts, deductions, charges, fees, withholdings, restrictions, conditions, interest, penalties and additional amounts being hereinafter collectively referred to as "Taxes"). If any Loan Party shall be required to deduct or to withhold any Taxes from or in respect of any amount payable hereunder or under any other Loan Document, (i) the amount so payable shall be increased so that after making all required deductions and withholdings (including Taxes on amounts payable pursuant to this sentence) the Lenders or the Agent, as the case may be, receive an amount equal to the sum they would have received had no such deduction or withholding been made, (ii) such Loan Party shall make such deduction or withholding, (iii) such Loan Party shall pay the full amount deducted or withheld to the relevant taxation authority in accordance with applicable law, and (iv) as promptly as possible thereafter, such Loan Party shall send the Lenders and the Agent an official receipt (or, if an official receipt is not available, such other documentation as shall be satisfactory to the Lenders or the Agent, as the case may be) evidencing payment of the amount or amounts so deducted or withheld. In addition, each Loan Party agrees to pay any present or future taxes, charges or similar levies which arise from any payment made hereunder or from the execution, delivery, performance, recordation or filing of, or otherwise with respect to, this Agreement or any other Loan Document other than the foregoing excluded taxes (hereinafter referred to as "Other Taxes"). (b) The Loan Parties hereby jointly and severally indemnify and agree to hold the Lenders and the Agent harmless from and against Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.08) paid by any Lender or the Agent and any liability (including penalties, interest and expenses for nonpayment, late payment or otherwise) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. Such indemnification shall be paid within 10 days from the date on which any such Lender or the Agent makes written demand therefor, which demand shall identify in reasonable detail the nature and amount of such Taxes or Other Taxes. (c) Each Lender that is organized in a jurisdiction outside the United States hereby agrees that it shall, no later than the Effective Date or, in the case of a Lender which becomes a party hereto pursuant to Section 12.07 hereof after the Effective Date, the date upon which such Lender becomes a party hereto (and from time to time thereafter upon the reasonable request of the Administrative Borrower or the Agent, but only if such Lender is legally able to do so), deliver to the Administrative Borrower and the Agent either (i) two accurate, complete and signed copies of either (x) U.S. Internal Revenue Service Form W-8ECI -32-

or successor form, or (y) U.S. Internal Revenue Service Form W-8BEN or successor form, in each case, indicating that such Lender is on the date of delivery thereof entitled to receive payments of interest hereunder free from, or subject to a reduced rate of, withholding of United States Federal income tax or (ii) in the case of such a Lender that is entitled to claim exemption from withholding of United States Federal income tax under Section 871(h) or Section 881(c) of the Internal Revenue Code, (x) a certificate to the effect that such Lender is (A) not a "bank" within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, (B) not a "10 percent shareholder" of the Parent within the meaning of Section 881(c)(3)(B) of the Internal Revenue Code and (C) not a controller foreign corporation receiving interest from a related person within the meaning of Section 881(c)(3)(C) of the Internal Revenue Code and (y) two accurate, complete and signed copies of U.S. Internal Revenue Service Form W-8BEN or successor form. (d) If any Loan Party fails to perform any of its obligations under this Section 2.08, the Loan Parties shall indemnify the Lenders and the Agent for any taxes, interest or penalties that may become payable as a result of any such failure. The obligations of the Loan Parties under this Section 2.08 shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder. Section 2.09 LIBOR Not Determinable; Illegality or Impropriety. (a) In the event, and on each occasion, that on or before the day on which LIBOR is to be determined in connection with the continuation of a LIBOR Loan as such or a conversion of a Reference Rate Loan into a LIBOR Loan pursuant to Section 2.11 hereof, the Agent has determined in good faith that, or has been advised by the Required Lenders that, (i) LIBOR cannot be reasonably determined for any reason, (ii) LIBOR will not adequately and fairly reflect the cost of maintaining LIBOR Loans or (iii) Dollar deposits in the principal amount of the applicable LIBOR Loans are not available in the interbank eurodollar market where the eurodollar and foreign currency and exchange operations in respect of the Lenders' LIBOR Loans are then being conducted, the Agent shall, as soon as practicable thereafter, give written notice of such determination to the Administrative Borrower and the other Lenders. In the event of any such determination, any request by the Administrative Borrower to continue a LIBOR Loan or to convert a Reference Rate Loan into a LIBOR Loan pursuant to Section 2.11 shall, until, (i) in the case of such a determination by the Required Lenders, the Agent has been advised by the Required Lenders and the Agent has so advised the Administrative Borrower that, or (ii) in the case of a determination by the Agent, the Agent has advised the Administrative Borrower and the other Lenders that, the circumstances giving rise to such notice no longer exist, be deemed to be a request for a Reference Rate Loan. Each determination by the Agent and/or the Required Lenders hereunder shall be conclusive and binding absent manifest error. (b) In the event that it shall be unlawful or improper for any Lender to make, maintain or fund any LIBOR Loan as contemplated by this Agreement, then such Lender shall forthwith give notice thereof to the Agent and the Administrative Borrower describing such illegality or impropriety in reasonable detail. Effective immediately upon the giving of such notice, the obligation of such Lender to continue to make LIBOR Loans shall be suspended for the duration of such illegality or impropriety and, if and when such illegality or impropriety ceases to exist, such suspension shall cease, and such Lender shall notify the Agent and the Administrative Borrower. If any such change shall make it unlawful or improper for any Lender to maintain any outstanding LIBOR Loan as a LIBOR Loan, such Lender shall, upon the happening of such event, notify the Agent and the Administrative Borrower, and the Administrative Borrower shall immediately, or if permitted by applicable law, rule, regulation, -33-

order, decree, interpretation, request or directive, at the end of the then current Interest Period for such LIBOR Loan, convert each such LIBOR Loan into a Reference Rate Loan. Section 2.10 Indemnity. (a) The Borrowers hereby jointly and severally indemnify each Lender against any loss or expense that such Lender actually sustains or incurs (including, without limitation, any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund or maintain any LIBOR Loan, and including loss of anticipated profits) as a consequence of (i) any failure by the Borrowers to fulfill on the date of any borrowing hereunder the applicable conditions set forth in Article V or in any Joinder Agreement, (ii) any failure by the Borrowers to borrow any LIBOR Loan hereunder, to convert any Reference Rate Loan into a LIBOR Loan or to continue a LIBOR Loan as such after notice of such borrowing, conversion or continuation has been given pursuant to Section 2.02 or 2.11 hereof, (iii) any payment, prepayment (mandatory or optional) or conversion of a LIBOR Loan required by any provision of this Agreement or otherwise made on a date other than the last day of the Interest Period applicable thereto, (iv) any default in payment or prepayment of the principal amount of any LIBOR Loan or any part thereof or interest accrued thereon, as and when due and payable (at the due date thereof, by notice of prepayment or otherwise), or (v) the occurrence of any Event of Default, including, in each such case, any loss (including, without limitation, loss of anticipated profits) or reasonable expense sustained or incurred in liquidating or employing deposits from third parties acquired to effect or maintain such Loan or any part thereof as a LIBOR Loan. Such loss or reasonable expense shall include but not be limited to an amount equal to the excess, if any, as reasonably determined by such Lender, of (i) its cost of obtaining the funds for the Loan being paid or prepaid or converted or continued or not borrowed or converted or continued (based on LIBOR applicable thereto) for the period from the date of such payment, prepayment, conversion, continuation or failure to borrow, convert or continue on the last day of the Interest Period for such Loan (or, in the case of a failure to borrow, convert or continue, the last day of the Interest Period for such Loan that would have commenced on the date of such failure to borrow, convert or continue) over (ii) the amount of interest (as reasonably determined by such Lender) that would be realized by such Lender in re-employing the funds so paid, prepaid, converted or continued or not borrowed, converted or continued for such Interest Period. A certificate of any Lender setting forth in reasonable detail any amount or amounts that such Lender is entitled to receive pursuant to this Section 2.10 and the basis for the determination of such amount or amounts shall be delivered to the Borrower and shall be conclusive and binding absent manifest error. (b) Notwithstanding paragraph (a) of this Section 2.10, the Agent will use reasonable efforts to minimize or reduce any such loss or expense resulting from the mandatory prepayments required by Section 2.05 of this Agreement by applying all payments and prepayments to Reference Rate Loans prior to any application of payments to LIBOR Loans. Section 2.11 Continuation and Conversion of Loans. Subject to Section 2.09 hereof, the Administrative Borrower shall have the right, at any time, on three (3) Business Days' prior irrevocable written or telecopy notice to the Agent, to continue any LIBOR Loan, or any portion thereof, into a subsequent Interest Period or to convert any Reference Rate Loan or portion thereof into a LIBOR Loan, subject to the following: (a) no LIBOR Loan may be continued as such and no Reference Rate Loan may be converted into a LIBOR Loan, when any Event of Default or Default shall have occurred and be continuing at such time, -34-

(b) in the case of a continuation of a LIBOR Loan as such or a conversion of a Reference Rate Loan into a LIBOR Loan, the aggregate principal amount of such LIBOR Loan shall not be less than $1,000,000 and in multiples of $500,000 if in excess thereof; (c) any portion of a Loan maturing or required to be repaid in less than one month may not be converted into or continued as a LIBOR Loan; and (d) if any conversion of a LIBOR Loan shall be effected on a day other than the last day of an Interest Period, the Borrowers shall reimburse each Lender on demand for any loss incurred or to be incurred or to be incurred by it in the reemployment of the funds released by such conversion as provided in Section 2.10 hereof. In the event that the Administrative Borrower shall not give notice to continue any LIBOR Loan into a subsequent Interest Period, such Loan shall automatically become a Reference Rate Loan at the expiration of the then current Interest Period. ARTICLE III [RESERVED] ARTICLE IV FEES, PAYMENTS AND OTHER COMPENSATION Section 4.01 Audit and Collateral Monitoring Fees. The Borrowers acknowledge that pursuant to Section 7.01(f), representatives of the Agent may visit any or all of the Loan Parties and/or conduct audits, inspections, valuations and/or field examinations of any or all of the Loan Parties at any time and from time to time in a manner so as to not unduly disrupt the business of the Loan Parties. The Borrower agrees to pay (i) $1,500 per day per examiner plus the examiner's out-of-pocket costs and reasonable expenses incurred in connection with all such visits, audits, inspections, valuations and field examinations and (ii) the cost of all visits, audits, inspections, valuations and field examinations conducted by a third party on behalf of the Agent. Section 4.02 Payments; Computations and Statements. (a) The Borrowers will make each payment under this Agreement not later than 12:00 noon (New York City time) on the day when due, in lawful money of the United States of America and in immediately available funds, to the Agent's Account. All payments received by the Agent after 12:00 noon (New York City time) on any Business Day will be credited to the Loan Account on the next succeeding Business Day. All payments shall be made by the Borrowers without set-off, counterclaim, deduction or other defense to the Agents and the Lenders. Except as provided in Section 2.02, after receipt, the Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal ratably to the Lenders in accordance with their Pro Rata Shares and like funds relating to the payment of any other amount payable to any Lender to such Lender, in each case to be applied in accordance with the terms of this Agreement, provided that the Agent will cause to be distributed all interest and fees received from or for the account of the Borrowers not less than once each month and in any event promptly after receipt thereof. The Lenders and the Borrowers hereby authorize the Agent to, and the Agent may, from time to time, charge the Loan Account of the Borrowers with any amount due and payable by the Borrowers under any Loan -35-

Document. Each of the Lenders and the Borrowers agrees that the Agent shall have the right to make such charges whether or not any Default or Event of Default shall have occurred and be continuing. Any amount charged to the Loan Account of the Borrowers shall be deemed a Loan hereunder made by the Lenders to the Borrowers, funded by the Agent on behalf of the Lenders and shall be added to the then outstanding principal amount of the Loans and thereafter shall bear interest as provided hereunder as if it had originally been part of the outstanding principal of the Term Loan B. Whenever any payment to be made under any such Loan Document shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall in such case be included in the computation of interest or fees, as the case may be. All computations of fees shall be made by the Agent on the basis of a year of 360 days for the actual number of days (including the first day but excluding the last day) occurring in the period for which such fees are payable. Each determination by the Agent of an interest rate or fees hereunder shall be conclusive and binding for all purposes in the absence of manifest error. (b) The Agent shall provide the Administrative Borrower, promptly after the end of each calendar month, a summary statement (in the form from time to time used by the Agent) of the opening and closing daily balances in the Loan Account of the Borrowers during such month, the amounts and dates of all Loans made to the Borrowers, the amounts and dates of all payments on account of the Loans during such month and the Loans to which such payments were applied, the amount of interest accrued on the Loans during such month, specifying the face amount thereof, and the amount and nature of any charges to the Loan Account made during such month on account of fees, commissions, expenses and other Obligations. All entries on any such statement shall be presumed to be correct and, thirty (30) days after the same is sent, shall be final and conclusive absent manifest error. Section 4.03 Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of any Obligation in excess of its ratable share of payments on account of similar obligations obtained by all the Lenders, such Lender shall forthwith purchase from the other Lenders such participations in such similar obligations held by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender's ratable share (according to the proportion of (i) the amount of such Lender's required repayment to (ii) the total amount so recovered from the purchasing Lender of any interest or other amount paid by the purchasing Lender in respect of the total amount so recovered). The Borrowers agree that any Lender so purchasing a participation from another Lender pursuant to this Section 4.03 may, to the fullest extent permitted by law, exercise all of its rights (including the Lender's right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrowers in the amount of such participation. Section 4.04 Apportionment of Payments.

(e) Notwithstanding any other terms set forth in the Loan Documents, the rights and remedies of the Agent and the Lenders herein provided, and the obligations of the Loan Parties set forth herein, are cumulative of, may be exercised singly or concurrently with, and are not exclusive of, any other rights, remedies or obligations set forth in any other Loan Document or as provided by law. Section 8.02 Accounts Receivable Documentation. After the occurrence and during the continuance of an Event of Default, and subject to the Intercreditor Agreement and the prior rights of the Revolving Credit Agent, each Loan Party will at such intervals as the Agent may require, execute and deliver confirmatory written assignments of the Accounts Receivable to the Agent and furnish such further schedules and/or information as the Agent may require relating to the Accounts Receivable, including, without limitation, sales invoices or the equivalent, credit memos issued, remittance advices, reports and copies of deposit slips and copies of original shipping or delivery receipts for all merchandise sold. In addition, the Loan Parties shall notify the Agent of any non-compliance in respect of the representations, warranties and covenants contained in Section 8.03. The items to be provided under this Section 8.02 are to be in form reasonably satisfactory to the Agent and are to be executed and delivered to the Agent from time to time solely for its convenience in maintaining records of the Collateral. The Loan Parties' failure to give any of such items to the Agent shall not affect, terminate, modify or otherwise limit the Agent's Lien on the Collateral. The Loan Parties shall not re-date any invoice or sale or make sales on extended dating beyond that customary in the Loan Parties' industry, and shall not re-bill any Accounts Receivable without promptly disclosing the same to the Agent and providing the Agent with a copy of such re-billing, identifying the same as such. If the Loan Parties become aware of anything materially detrimental to any of the Loan Parties' customers' credit, the Loan Parties will promptly advise the Agent thereof. Section 8.03 Status of Accounts Receivable and Other Collateral. With respect to Collateral of any Loan Party at the time the Collateral becomes subject to the Agent's Lien, each Loan Party covenants, represents and warrants: (a) each Account Receivable shall be a good and valid account representing an undisputed bona fide indebtedness incurred or an amount indisputably owed by the Account Debtor therein named, for a fixed sum as set forth in the invoice relating thereto with respect to an absolute sale and delivery upon the specified terms of goods sold or services rendered by such Loan Party; (b) no Account Receivable shall be subject to any known defense, offset, counterclaim, discount or allowance except as may be stated in the invoice relating thereto, discounts and allowances as may be customary in such Loan Party's business and as otherwise disclosed to the Agent; (c) none of the transactions underlying or giving rise to any Account Receivable shall violate any applicable state or federal laws or regulations, and all documents relating thereto shall be legally sufficient under such laws or -78-

regulations and shall be legally enforceable in accordance with their terms; (e) all agreements, instruments and other documents relating to any Account Receivable shall be true and correct and in all material respects what they purport to be; (f) all signatures and endorsements that appear on all material agreements, instruments and other documents relating to any Account Receivable shall be genuine and all signatories and endorsers shall have full capacity to contract; (g) such Loan Party will, immediately upon learning thereof, report to the Agent any material loss or destruction of, or substantial damage to, any of the Collateral, and any other matters affecting the value, enforceability or collectibility of any of the Collateral; and (h) such Loan Party is not and shall not be entitled to pledge the Agent's or any Lender's credit on any purchases or for any purpose whatsoever. Section 8.04 Collateral Custodian. (a)Without limiting the Agent's or the Lenders' rights with respect to the Collateral, the Agent has implemented an arrangement, on terms and pursuant to written agreements in form and substance satisfactory to the Agent, pursuant to which a third party collateral custodian or agent, acceptable to the Agent (together with any substitute or supplemental collateral custodian or agent, the "Rolling Stock Collateral Custodian") has been engaged, at the expense of the Borrowers, to hold physical possession of original certificates of title or ownership, vehicle registrations and other similar instruments and documents with respect to the Rolling Stock included in the Collateral, upon which certificates of title or ownership the Agent's Liens shall be noted, and pursuant to which arrangements, on terms and conditions satisfactory to the Agent, the Rolling Stock Collateral Custodian will, among other things, monitor and render reports to the Agent regarding the acquisition and disposition of such Rolling Stock by the Loan Parties as permitted by this Agreement, and receive and maintain documentation evidencing compliance with vehicle titling and registration requirements under applicable law (including, without limitation, all Motor Vehicle Law), and will assist and cooperate with the Agent in making the necessary arrangements for such Liens and any releases thereof with respect to the dispositions of Rolling Stock permitted under this Agreement. (b) Subject to the terms of the Intercreditor Agreement, upon the occurrence and during the continuance of any Default or Event of Default, the Agent may at any time and from time to time employ and maintain on the premises of any Loan Party a custodian selected by the Agent who shall have full authority to do all acts necessary to protect the Agent's and the Lenders' interests. Each Loan Party hereby agrees to, and to cause its Subsidiaries to, cooperate with any such custodian and to do whatever the Agent may reasonably request to preserve the Collateral. All costs and expenses incurred by the Agent by reason of the employment of the custodian shall be the responsibility of the Borrowers and charged to the Loan Account.

ARTICLE X AGENT Section 10.01 Appointment. Each Lender (and each subsequent maker of any Loan by its making thereof) hereby irrevocably appoints and authorizes the Agent to perform the duties of the Agent as set forth in this Agreement including: (i) to receive on behalf of each Lender any payment of principal of or interest on the Loans outstanding hereunder and all other amounts accrued hereunder for the account of the Lenders and paid to the Agent, and, subject to Section 2.02 of this Agreement, to distribute promptly to each Lender its Pro Rata Share of all payments so received; (ii) to distribute to each Lender copies of all material notices and agreements received by the Agent and not required to be delivered to each Lender pursuant to the terms of this Agreement, provided that the Agent shall not have any liability to the Lenders for the Agent's inadvertent failure to distribute any such notices or agreements to the Lenders; (iii) to maintain, in accordance with its customary business practices, ledgers and records reflecting the status of the Obligations, the Loans, and related matters and to maintain, in accordance with its customary business practices, ledgers and records reflecting the status of the Collateral and related matters; (iv) to execute or file any and all financing or similar statements or notices, amendments, renewals, supplements, documents, instruments, proofs of claim, notices and other -83-

As to any matters not expressly provided for by this Agreement and the other Loan Documents (including, without limitation, enforcement or collection of the Loans), the Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Lenders, and such instructions of the Required Lenders shall be binding upon all Lenders and all makers of Loans; provided, however, that the Agent shall not be required to take any action which, in the reasonable opinion of the Agent, exposes the Agent to liability or which is contrary to this Agreement or any other Loan Document or applicable law. Section 10.02 Nature of Duties. The Agent shall have no duties or responsibilities except those expressly set forth in this Agreement or in the other Loan Documents. The duties of the Agent shall be mechanical and administrative in nature. The Agent shall not have by reason of this Agreement or any other Loan Document a fiduciary relationship in respect of any Lender. Nothing in this Agreement or any other Loan Document, express or implied, is intended to or shall be construed to impose upon the Agent any obligations in respect of this Agreement or any other Loan Document except as expressly set forth herein or therein. Each Lender shall make its own independent investigation of the financial condition and affairs of the Loan Parties in connection with the making and the continuance of the Loans hereunder and shall make its own appraisal of the creditworthiness of the Loan Parties and the value of the Collateral, and the Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Lender with any credit or other information with respect thereto, whether coming into its possession before the initial Loan hereunder or at any time or times thereafter, provided that, upon the reasonable request of a Lender, the Agent shall provide to such Lender any documents or reports delivered to the Agent by the Loan Parties pursuant to the terms of this Agreement or any other Loan Document. If the Agent seeks the consent or approval of the Required Lenders to the taking or refraining from taking any action hereunder, the Agent shall send notice thereof to each Lender. The Agent shall promptly notify each Lender any time that the Required Lenders have instructed the Agent to act or refrain from acting pursuant hereto. Section 10.03 Rights, Exculpation, Etc. The Agent and its directors, officers, agents or employees shall not be liable for any action taken or omitted to be taken by them under or in connection with this Agreement or the other Loan Documents, except for their own gross negligence or willful misconduct as determined by a final judgment of a court of competent -84-

jurisdiction. Without limiting the generality of the foregoing, the Agent (i) may treat the payee of any Loan as the owner thereof until the Agent receives written notice of the assignment or transfer thereof, pursuant to Section 12.07 hereof, signed by such payee and in form satisfactory to the Agent; (ii) may consult with legal counsel (including, without limitation, counsel to the Agent or counsel to the Loan Parties), independent public accountants, and other experts selected by any of them and shall not be liable for any action taken or omitted to be taken in good faith by any of them in accordance with the advice of such counsel or experts; (iii) make no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, certificates, warranties or representations made in or in connection with this Agreement or the other Loan Documents; (iv) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement or the other Loan Documents on the part of any Person, the existence or possible existence of any Default or Event of Default, or to inspect the Collateral or other property (including, without limitation, the books and records) of any Person; (v) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or the other Loan Documents or any other instrument or document furnished pursuant hereto or thereto; and (vi) shall not be deemed to have made any representation or warranty regarding the existence, value or collectibility of the Collateral, the existence, priority or perfection of the Agent's Lien thereon, or any certificate prepared by any Loan Party in connection therewith, nor shall the Agent be responsible or liable to the Lenders for any failure to monitor or maintain any portion of the Collateral. The Agent shall not be liable for any apportionment or distribution of payments made in good faith pursuant to Section 4.04, and if any such apportionment or distribution is subsequently determined to have been made in error the sole recourse of any Lender to whom payment was due but not made, shall be to recover from other Lenders any payment in excess of the amount which they are determined to be entitled. The Agent may at any time request instructions from the Lenders with respect to any actions or approvals which by the terms of this Agreement or of any of the other Loan Documents the Agent is permitted or required to take or to grant, and if such instructions are promptly requested, the Agent shall be absolutely entitled to refrain from taking any action or to withhold any approval under any of the Loan Documents until it shall have received such instructions from the Required Lenders. Without limiting the foregoing, no Lender shall have any right of action whatsoever against the Agent as a result of the Agent acting or refraining from acting under this Agreement or any of the other Loan Documents in accordance with the instructions of the Required Lenders. Section 10.04 Reliance. The Agent shall be entitled to rely upon any written notices, statements, certificates, orders or other documents or any telephone message believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper Person, and with respect to all matters pertaining to this Agreement or any of the other Loan Documents and its duties hereunder or thereunder, upon advice of counsel selected by it. Section 10.05 Indemnification. To the extent that the Agent is not reimbursed and indemnified by any Loan Party, the Lenders will reimburse and indemnify the Agent from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses, advances or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Agent in any way relating to or arising out of this Agreement or any of the other Loan Documents or any action taken or omitted by the Agent under this Agreement or any of the other Loan Documents, in proportion to each Lender's Pro Rata Share, including, without limitation, advances and disbursements made pursuant to -85-

Section 10.08; provided, however, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses, advances or disbursements for which there has been a final judicial determination that such liability resulted from the Agent's gross negligence or willful misconduct. The obligations of the Lenders under this Section 10.05 shall survive the payment in full of the Loans and the termination of this Agreement. Section 10.06 Agent Individually. With respect to its Pro Rata Share of the Total Commitment hereunder and the Loans made by it, the Agent shall have and may exercise the same rights and powers hereunder and is subject to the same obligations and liabilities as and to the extent set forth herein for any other Lender or maker of a Loan. The terms "Lenders" or "Required Lenders" or any similar terms shall, unless the context clearly otherwise indicates, include the Agent in its individual capacity as a Lender or one of the Required Lenders. The Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of banking, trust or other business with any Borrower as if it were not acting as the Agent pursuant hereto without any duty to account to the other Lenders. Section 10.07 Successor Agent. (a) The Agent may resign from the performance of all its functions and duties hereunder and under the other Loan Documents at any time by giving at least thirty (30) Business Days' prior written notice to the Administrative Borrower and each Lender. Such resignation shall take effect upon the acceptance by a successor Agent of appointment pursuant to clauses (b) and (c) below or as otherwise provided below. (b) Upon any such notice of resignation, the Required Lenders shall appoint a successor Agent. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the Agent, and the Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. After the Agent's resignation hereunder as the Agent, the provisions of this Article X shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Agent under this Agreement and the other Loan Documents. (c) If a successor Agent shall not have been so appointed within said thirty (30) Business Day period, the Agent shall then appoint a successor Agent who shall serve as the Agent until such time, if any, as the Required Lenders appoint a successor Agent as provided above. Section 10.08 Collateral Matters. (a) The Agent may from time to time make such disbursements and advances ("Agent Advances") which the Agent, in its sole discretion, deems necessary or desirable to preserve, protect, prepare for sale or lease or dispose of the Collateral or any portion thereof, to enhance the likelihood or maximize the amount of repayment by the Borrowers of the Loans and other Obligations or to pay any other amount chargeable to the Borrowers pursuant to the terms of this Agreement, including, without limitation, costs, fees and expenses as described in Section 12.04. The Agent Advances shall be repayable on demand, be secured by the Collateral and bear interest at a rate per annum equal to the rate of interest then applicable to the Term Loan B. The Agent Advances shall constitute Obligations hereunder which may be charged to the Loan Account in accordance with Section 4.02. The Agent shall notify each -86-

Lender and the Administrative Borrower in writing of each such Agent Advance, which notice shall include a description of the purpose of such Agent Advance. Without limitation to its obligations pursuant to Section 10.05, each Lender agrees that it shall make available to the Agent, upon the Agent's demand, in Dollars in immediately available funds, the amount equal to such Lender's Pro Rata Share of each such Agent Advance. If such funds are not made available to the Agent by such Lender, the Agent shall be entitled to recover such funds on demand from such Lender, together with interest thereon for each day from the date such payment was due until the date such amount is paid to the Agent, at the Federal Funds Rate for three Business Days and thereafter at the Reference Rate. (b) The Lenders hereby irrevocably authorize the Agent, at its option and in its discretion, to release any Lien granted to or held by the Agent upon any Collateral upon termination of the Total Commitment and payment and satisfaction of all Loans and all other Obligations which have matured and which the Agent has been notified in writing are then due and payable; or constituting property being sold or disposed of in the ordinary course of any Loan Party's business and in compliance with the terms of this Agreement and the other Loan Documents; or constituting property in which the Loan Parties owned no interest at the time the Lien was granted or at any time thereafter; or if approved, authorized or ratified in writing by the Lenders. Upon request by the Agent at any time, the Lenders will confirm in writing the Agent's authority to release particular types or items of Collateral pursuant to this Section 10.08(b). (c) Without in any manner limiting the Agent's authority to act without any specific or further authorization or consent by the Lenders (as set forth in Section 10.08(b)), each Lender agrees to confirm in writing, upon request by the Agent, the authority to release Collateral conferred upon the Agent under Section 10.08(b). Upon receipt by the Agent of confirmation from the Lenders of its authority to release any particular item or types of Collateral, and upon prior written request by any Loan Party, the Agent shall (and is hereby irrevocably authorized by the Lenders to) execute such documents as may be necessary to evidence the release of the Liens granted to the Agent for the benefit of the Lenders upon such Collateral; provided, however, that (i) the Agent shall not be required to execute any such document on terms which, in the Agent's opinion, would expose the Agent to liability or create any obligations or entail any consequence other than the release of such Liens without recourse or warranty, and (ii) such release shall not in any manner discharge, affect or impair the Obligations or any Lien upon (or obligations of any Loan Party in respect of) all interests in the Collateral retained by any Loan Party. (d) The Agent shall have no obligation whatsoever to any Lender to assure that the Collateral exists or is owned by the Loan Parties or is cared for, protected or insured or has been encumbered or that the Lien granted to the Agent pursuant to this Agreement or any other Loan Document has been properly or sufficiently or lawfully created, perfected, protected or enforced or is entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure or fidelity, or to continue exercising, any of the rights, authorities and powers granted or available to the Agent in this Section 10.08 or in any other Loan Document, it being understood and agreed that in respect of the Collateral, or any act, omission or event related thereto, the Agent may act in any manner it may deem appropriate, in its sole discretion, given the Agent's own interest in the Collateral as one of the Lenders and that the Agent shall have no duty or liability whatsoever to any other Lender, except as otherwise provided herein. -87-

Section 10.09 Agency for Perfection. Each Lender hereby appoints the Agent and each other Lender as agent and bailee for the purpose of perfecting the security interests in and liens upon the Collateral in assets which, in accordance with Article 9 of the Uniform Commercial Code, can be perfected only by possession or control (or where the security interest of a secured party with possession or control has priority over the security interest of another secured party) and each Agent and each Lender hereby acknowledges that it holds possession of or otherwise controls any such Collateral for the benefit of the Agent and the Lenders as secured party. Should any Lender obtain possession or control of any such Collateral, such Lender shall notify the Agent thereof, and, promptly upon the Agent's request therefor shall deliver such Collateral to the Agent or in accordance with the Agent's instructions. Each Loan Party by its execution and delivery of this Agreement hereby consents to the foregoing. ARTICLE XI GUARANTY Section 11.01 Guaranty. Each Guarantor hereby unconditionally and irrevocably guarantees the punctual payment when due, whether at stated maturity, by acceleration or otherwise, of all Obligations of the Borrowers now or hereafter existing under any Loan Document, whether for principal, interest (including, without limitation, all interest that accrues after the commencement of any Insolvency Proceeding of any Borrower whether or not allowed in such proceeding), fees, commissions, expense reimbursements, indemnifications or otherwise (such obligations, to the extent not paid by the Borrowers, being the "Guaranteed Obligations"), and agrees to pay any and all expenses (including reasonable counsel fees and expenses) incurred by the Agent and the Lenders in enforcing any rights under the guaranty set forth in this Article XI. Without limiting the generality of the foregoing, each Guarantor's liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by the Borrowers to the Agent and the Lenders under any Loan Document but for the fact that they are unenforceable or not allowable due to the existence of an Insolvency Proceeding involving any Borrower. In no event shall the obligation of any Guarantor hereunder exceed the maximum amount such Guarantor could guarantee under any bankruptcy, insolvency or other similar law. Section 11.02 Guaranty Absolute. Each Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Loan Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Agent or the Lenders with respect thereto. The obligations of each Guarantor under this Article XI are independent of the Guaranteed Obligations, and a separate action or actions may be brought and prosecuted against each Guarantor to enforce such obligations, irrespective of whether any action is brought against any Loan Party or whether any Loan Party is joined in any such action or actions. The liability of each Guarantor under this Article XI shall be irrevocable, absolute and unconditional irrespective of, and each Guarantor hereby irrevocably waives any defenses it may now or hereafter have in any way relating to, any or all of the following: (a) any lack of validity or enforceability of any Loan Document or any agreement or instrument relating thereto; (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Guaranteed Obligations, or any other amendment or waiver of or any consent to departure from any Loan Document, including, without limitation, any increase in -88-

the Guaranteed Obligations resulting from the extension of additional credit to any Loan Party or otherwise; (c) any taking, exchange, release or non-perfection of any Collateral, or any taking, release or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Guaranteed Obligations; (d) any change, restructuring or termination of the corporate, limited liability company or partnership structure or existence of any Loan Party; or (e) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by the Agents or the Lenders that might otherwise constitute a defense available to, or a discharge of, any Loan Party or any other guarantor or surety. This Article XI shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be returned by the Agent, the Lenders or any other Person upon the insolvency, bankruptcy or reorganization of any Borrower or otherwise, all as though such payment had not been made. Section 11.03 Waiver. Each Guarantor hereby waives promptness, diligence, notice of acceptance and any other notice with respect to any of the Guaranteed Obligations and this Article XI and any requirement that the Agent or the Lenders exhaust any right or take any action against any Loan Party or any other Person or any Collateral. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated herein and that the waiver set forth in this Section 11.03 is knowingly made in contemplation of such benefits. Each Guarantor hereby waives any right to revoke this Article XI, and acknowledges that this Article XI is continuing in nature and applies to all Guaranteed Obligations, whether existing now or in the future. Section 11.04 Continuing Guaranty; Assignments. This Article XI is a continuing guaranty and shall (a) remain in full force and effect until the later of the cash payment in full of the Guaranteed Obligations (other than indemnification obligations as to which no claim has been made) and all other amounts payable under this Article XI and the Termination Date, (b) be binding upon each Guarantor, its successors and assigns and (c) inure to the benefit of and be enforceable by the Agent and the Lenders and their successors, pledgees, transferees and assigns. Without limiting the generality of the foregoing clause (c), any Lender may pledge, assign or otherwise transfer all or any portion of its rights and obligations under this Agreement (including, without limitation, all or any portion of its Commitments and its Loans) to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted such Lender herein or otherwise, in each case as provided in Section 12.07. Section 11.05 Subrogation. No Guarantor will exercise any rights that it may now or hereafter acquire against any Loan Party or any other guarantor that arise from the existence, payment, performance or enforcement of such Guarantor's obligations under this Article XI, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of the Agent and the Lenders against any Loan Party or any other guarantor or any Collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, -89-

without limitation, the right to take or receive from any Loan Party or any other guarantor, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security solely on account of such claim, remedy or right, unless and until all of the Guaranteed Obligations and all other amounts payable under this Article XI shall have been paid in full in cash and the Termination Date shall have occurred. If any amount shall be paid to any Guarantor in violation of the immediately preceding sentence at any time prior to the later of the payment in full in cash of the Guaranteed Obligations and all other amounts payable under this Article XI and the Termination Date, such amount shall be held in trust for the benefit of the Agent and the Lenders and shall forthwith be paid to the Agent and the Lenders to be credited and applied to the Guaranteed Obligations and all other amounts payable under this Article XI, whether matured or unmatured, in accordance with the terms of this Agreement, or to be held as Collateral for any Guaranteed Obligations or other amounts payable under this Article XI thereafter arising. If (i) any Guarantor shall make payment to the Agent and the Lenders of all or any part of the Guaranteed Obligations, (ii) all of the Guaranteed Obligations and all other amounts payable under this Article XI shall be paid in full in cash and (iii) the Termination Date shall have occurred, the Agent and the Lenders will, at such Guarantor's request and expense, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Guaranteed Obligations resulting from such payment by such Guarantor. Section 11.06 Judgment Currency. The specification under this Agreement of Dollars and payment in New York City is of the essence. Each Guarantor's obligations hereunder and under the other Loan Documents to make payments inDollars and shall not be discharged or satisfied by any tender or recovery pursuant to any judgment expressed in or converted into any currency other than Dollars, except to the extent that such tender or recovery results in the effective receipt by the Lenders or the Agent of the full amount of Dollars expressed to be payable to the Agent and the Lenders under this Agreement or the other Loan Documents. If, for the purpose of obtaining or enforcing judgment in any court, it is necessary to convert into or from any currency other than Dollars (such other currency being hereinafter referred to as the "Judgment Currency") an amount due in Dollars, the rate of exchange used shall be that at which the Lenders or the Agent could, in accordance with normal banking procedures, purchase Dollars with the Judgment Currency on the Business Day preceding that on which final judgment is given. The obligation of each Guarantor in respect of any such sum due from it to the Lender or the Agent hereunder shall, notwithstanding any judgment in such Judgment Currency, be discharged only to the extent that, on the Business Day immediately following the date on which the Lender or the Agent receives any sum adjudged to be so due in the Judgment Currency, the Lenders or the Agent may, in accordance with normal banking procedures, purchase Dollars with the Judgment Currency. If the Dollars so purchased are less than the sum originally due to the Agent or the Lender in Dollars, each Guarantor agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Lenders or the Agent against such loss, and if the Dollars so purchased exceed the sum originally due to the Lenders or the Agent in Dollars, the Lenders or the Agent agrees to remit to such Guarantor such excess. -90-

Section 12.03 No Waiver; Remedies, Etc. No failure on the part of the Agent or any Lender to exercise, and no delay in exercising, any right hereunder or under any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any right under any Loan Document preclude any other or further exercise thereof or the exercise of any other right. The rights and remedies of the Agent and the Lenders provided herein and in the other Loan Documents are cumulative and are in addition to, and not exclusive of, any rights or remedies provided by law.

Section 12.05 Right of Set-off. Upon the occurrence and during the continuance of any Event of Default, any Agent or any Lender may, and is hereby authorized to, at any time and from time to time, without notice to any Loan Party (any such notice being expressly waived by the Loan Parties) and to the fullest extent permitted by law, set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other Indebtedness at any time owing by the Agent or such Lender to or for the credit or the account of any Loan Party against any and all obligations of the Loan Parties either now or hereafter existing under any Loan Document, irrespective of whether or not the Agent or such Lender shall have made any demand hereunder or thereunder and although such obligations may be contingent or unmatured. The Agent and each Lender agrees to notify such Loan Party promptly after any such set-off and application made by the Agent or such Lender provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Agent and the Lenders under this Section 12.05 are in addition to the other rights and remedies (including other rights of set-off) which the Agent and the Lenders may have under this Agreement or any other Loan Documents of law or otherwise. -93-

(b) Each Lender may, with the written consent of the Agent (provided that no written consent of the Agent shall be required in connection with any assignment by a Lender (i) to an Affiliate of such Lender or a Related Fund or (ii) during the existence of an Event of Default), assign to one or more other lenders or other entities all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitments and the Loans made by it); provided, however, that (i) such assignment is in an amount which is at least $1,000,000 or a multiple of $1,000,000 in excess thereof (or the remainder of such Lender's Commitment) (except such minimum amount shall not apply to an assignment by a Lender to an Affiliate of such Lender or a fund or account managed by such Lender or an Affiliate of such Lender), (ii) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance, an Assignment and Acceptance, together with any promissory note subject to such assignment and such parties shall deliver to the Agent a processing and recordation fee of $3,500 (except the payment of such fee shall not be required in connection with an assignment by a Lender to an Affiliate of such Lender or a Related Fund) and (iii) no written consent of the Agent shall be required in connection with any assignment by a Lender to an Affiliate of such Lender or a Related Fund. Upon such execution, delivery and acceptance, from and after the effective date specified in each Assignment and Acceptance, which effective date shall be at least three Business Days after the delivery thereof to the Agent (or such shorter period as shall be agreed to by the Agent and the parties to such assignment), (A) the assignee thereunder shall become a "Lender" hereunder and, in addition to the rights and obligations hereunder held by it immediately prior to such effective date, have the rights and obligations hereunder that have been assigned to it pursuant to such Assignment and Acceptance and (B) the assigning Lender thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto). (i) By executing and delivering an Assignment and Acceptance, the assigning Lender and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (A) other than as provided in such Assignment and Acceptance, the assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or any other Loan Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other Loan Document furnished pursuant hereto; (B) the assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of any Loan Party or any of its -94-

Subsidiaries or the performance or observance by any Loan Party of any of its obligations under this Agreement or any other Loan Document furnished pursuant hereto; (C) such assignee confirms that it has received a copy of this Agreement and the other Loan Documents, together with such other documents and information it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (D) such assignee will, independently and without reliance upon the assigning Lender, the Agent or any Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents; (E) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to the Agent by the terms hereof and thereof, together with such powers as are reasonably incidental hereto and thereto; and (F) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement and the other Loan Documents are required to be performed by it as a Lender. (ii) The Agent shall, on behalf of the Borrowers, maintain, or cause to be maintained, at the Payment Office a copy of each Assignment and Acceptance delivered to and accepted by it and a register (the "Register") for the recordation of the names and addresses of the Lenders and the Commitments of, and principal amount of the Loans (the "Registered Loans") owing to each Lender from time to time. The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrowers, the Agent and the Lenders shall treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Administrative Borrower and any Lender at any reasonable time and from time to time upon reasonable prior notice. In the event any assignment permitted under Section 12.07(b) is not reflected in the Register, the assigning Lender shall maintain a register comparable to the Register in order to reflect such assignment. (iii) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an assignee, together with any promissory notes subject to such assignment, the Agent shall, if the Agent consents to such assignment and if such Assignment and Acceptance has been completed (i) accept such Assignment and Acceptance and (ii) record the information contained therein in the Register. (iv) A Registered Loan (and the registered note, if any, evidencing the same) may be assigned or sold in whole or in part only by registration of such assignment or sale on the Register (and each registered note shall expressly so provide). Any assignment or sale of all or part of such Registered Loan (and the registered note, if any, evidencing the same) may be effected only by registration of such assignment or sale on the Register, together with the surrender of the registered note, if any, evidencing the same duly endorsed by (or accompanied by a written instrument of assignment or sale duly executed by) the holder of such registered note, whereupon, at the request of the designated assignee(s) or transferee(s), one or more new registered notes in the same aggregate principal amount shall be issued to the designated assignee(s) or transferee(s). Prior to the registration of assignment or sale of any Registered Loan (and the registered note, if any, evidencing the same), the Agent shall treat the Person in whose name such Registered Loan (and the registered note, if any, evidencing the same) is registered as the owner thereof for the purpose of receiving all payments thereon and for all other purposes, notwithstanding notice to the contrary. -95-

(v) In the event that any Lender sells participations in a Registered Loan, such Lender shall maintain a register on which it enters the name of all participants in the Registered Loans held by it (the "Participant Register"). A Registered Loan (and the registered note, if any, evidencing the same) may be participated in whole or in part only by registration of such participation on the Participant Register (and each registered note shall expressly so provide). Any participation of such Registered Loan (and the registered note, if any, evidencing the same) may be effected only by the registration of such participation on the Participant Register. (vi) Any foreign Person who purchases or is assigned or participates in any portion of such Registered Loan shall provide the Agent and the Lender with a completed Internal Revenue Service Form W-8BEN (Certificate of Foreign Status) or a substantially similar form for such purchaser, participant or any other affiliate who is a holder of beneficial interests in the Registered Loan. (c) Each Lender holding a Term Loan A agrees that, until the 90/th/ day after the Effective Date, it will, at the written request of the Administrative Borrower, assign all or a portion of its interest in the Term Loan A to one or more other lenders not a party hereto that are proposed by the Borrowers so long as (i) such assignment shall be effected in accordance with Section 12.07(b), except that (A) the amount of such assignment shall be at least $5,000,000 or a multiple of $1,000,000 in excess thereof and (B) the Agent shall not charge the $3,500 processing and recordation fee in connection with such assignment, (ii) such assignment shall be on customary commercial terms and conditions (without representation, warranty or recourse by the assigning Lender), (iii) the rate of interest on the Term Loan A assigned to such other lender shall be equal to or less than LIBOR plus 7.25% per annum and (iv) no Event of Default shall exist either immediately before or after giving effect to such assignment. (d) Each Lender may sell participations to one or more banks or other entities in or to all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including, without limitation, all or a portion of its Commitments and the Loans made by it); provided, that (i) such Lender's obligations under this Agreement (including without limitation, its Commitments hereunder) and the other Loan Documents shall remain unchanged; (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and the Borrowers, the Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement and the other Loan Documents; and (iii) a participant shall not be entitled to require such Lender to take or omit to take any action hereunder except (A) action directly effecting an extension of the maturity dates or decrease in the principal amount of the Loans, (B) action directly effecting an extension of the due dates or a decrease in the rate of interest payable on the Loans or the fees payable under this Agreement, or (C) actions directly effecting a release of all or a substantial portion of the Collateral or any Loan Party (except as set forth in Section 10.08 of this Agreement or any other Loan Document). The Loan Parties agree that each participant shall be entitled to the benefits of Section 2.08 and Section 4.05 of this Agreement with respect to its participation in any portion of the Commitments and the Loans as if it was a Lender. Section 12.08 Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of this Agreement by telecopier shall be equally -96-

as effective as delivery of an original executed counterpart of this Agreement. Any party delivering an executed counterpart of this Agreement by telecopier also shall deliver an original executed counterpart of this Agreement but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Agreement. The foregoing shall apply to each other Loan Document mutatis mutandis. Section 12.09 GOVERNING LAW.

TO THE EXTENT THAT ANY LOAN PARTY HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, EACH LOAN PARTY HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS. Section 12.11 WAIVER OF JURY TRIAL, ETC. EACH LOAN PARTY, THE AGENT AND EACH LENDER HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM CONCERNING ANY -97-

Except as otherwise expressly set forth herein to the contrary, if the consent, approval, satisfaction, determination, judgment, acceptance or similar action (an "Action") of the Agent or any Lender shall be permitted or required pursuant to any provision hereof or any provision of any other agreement to which any Loan Party is a party and to which the Agent or any Lender has succeeded thereto, such Action shall be required to be in writing and may be withheld or denied by the Agent or such Lender, in its sole discretion, with or without any reason, and without being subject to question or challenge on the grounds that such Action was not taken in good faith. Section 12.13 No Party Deemed Drafter. Each of the parties hereto agrees that no party hereto shall be deemed to be the drafter of this Agreement. Section 12.14 Reinstatement; Certain Payments. If any claim is ever made upon the Agent or any Lender for repayment or recovery of any amount or amounts received by the Agent or such Lender in payment or on account of any of the Obligations, the Agent or such Lender shall give prompt notice of such claim to each other Lender and the Administrative Borrower, and if the Agent or such Lender repays all or part of such amount by reason of (i) any judgment, decree or order of any court or administrative body having jurisdiction over the Agent or such Lender or any of its property, or (ii) any good faith settlement or compromise of any such claim effected by the Agent or such Lender with any such claimant, then and in such event each Loan Party agrees that (A) any such judgment, decree, order, settlement or compromise shall be binding upon it notwithstanding the cancellation of any Indebtedness hereunder or under the other Loan Documents or the termination of this Agreement or the other Loan Documents, and (B) it shall be and remain liable to the Agent or such Lender hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by the Agent or such Lender. Section 12.15 Indemnification. (a) General Indemnity. In addition to each Loan Party's other Obligations under this Agreement, each Loan Party agrees to, jointly and severally, defend, protect, indemnify and hold harmless the Agent and each Lender and all of their respective officers, directors, employees, attorneys, consultants and agents (collectively called the "Indemnitees") from and against any and all losses, damages, liabilities, obligations, penalties, fees, reasonable costs and expenses (including, without limitation, reasonable -98-

attorneys' fees, costs and expenses) incurred by such Indemnitees, whether prior to or from and after the Effective Date, whether direct, indirect or consequential, as a result of or arising from or relating to or in connection with any of the following: (i) the negotiation, preparation, execution or performance or enforcement of this Agreement, any other Loan Document or of any other document executed in connection with the transactions contemplated by this Agreement, (ii) the Agent's or any Lender's furnishing of funds to the Borrowers under this Agreement or the other Loan Documents, including, without limitation, the management of any such Loans, (iii) any matter relating to the financing transactions contemplated by this Agreement or the other Loan Documents or by any document executed in connection with the transactions contemplated by this Agreement or the other Loan Documents, or (iv) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnitee is a party thereto (collectively, the "Indemnified Matters"); provided, however, that the Loan Parties shall not have any obligation to any Indemnitee under this subsection (a) for any Indemnified Matter caused by the gross negligence or willful misconduct of such Indemnitee, as determined by a final judgment of a court of competent jurisdiction. (b) Environmental Indemnity. Without limiting Section 12.15(a) hereof, each Loan Party agrees to, jointly and severally, defend, indemnify, and hold harmless the Indemnitees against any and all Environmental Liabilities and all other claims, demands, penalties, fines, liability (including strict liability), losses, damages, costs and expenses (including without limitation, reasonable legal fees and expenses, consultant fees and laboratory fees), arising out of (i) any Releases or threatened Releases (x) at any property presently or formerly owned or operated by any Loan Party or any Subsidiary of any Loan Party, or any predecessor in interest, or (y) of any Hazardous Materials generated and disposed of by any Loan Party or any Subsidiary of any Loan Party, or any predecessor in interest; (ii) any violations of Environmental Laws; (iii) any Environmental Claim relating to any Loan Party or any Subsidiary of any Loan Party, or any predecessor in interest; (iv) any personal injury (including wrongful death) or property damage (real or personal) arising out of exposure to Hazardous Materials used, handled, generated, transported or disposed by any Loan Party or any Subsidiary of any Loan Party, or any predecessor in interest; and (v) any breach of any warranty or representation regarding environmental matters made by the Loan Parties in Section 6.01(r) or the breach of any covenant made by the Loan Parties in Section 7.01(j). Notwithstanding the foregoing, the Loan Parties shall not have any obligation to any Indemnitee under this subsection (b) regarding any potential environmental matter covered hereunder which is caused by the gross negligence or willful misconduct of such Indemnitee, as determined by a final judgment of a court of competent jurisdiction. (c) The indemnification for all of the foregoing losses, damages, fees, costs and expenses of the Indemnitees are chargeable against the Loan Account. To the extent that the undertaking to indemnify, pay and hold harmless set forth in this Section 12.15 may be unenforceable because it is violative of any law or public policy, each Loan Party shall, jointly and severally, contribute the maximum portion which it is permitted to pay and satisfy under applicable law, to the payment and satisfaction of all Indemnified Matters incurred by the Indemnitees. The indemnities set forth in this Section 12.15 shall survive the repayment of the Obligations and discharge of any Liens granted under the Loan Documents. Section 12.16 Agent for Borrowers. Each Borrower hereby irrevocably appoints Clean Harbors, Inc. as the borrowing agent and attorney-in-fact for the Borrowers (the "Administrative Borrower") which appointment shall remain in full force and effect unless and -99-

until the Agent shall have received prior written notice signed by all of the Borrowers that such appointment has been revoked and that another Borrower has been appointed Administrative Borrower. Each Borrower hereby irrevocably appoints and authorizes the Administrative Borrower (i) to provide to the Agent and receive from the Agent all notices with respect to Loans obtained for the benefit of any Borrower and all other notices and instructions under this Agreement and (ii) to take such action as the Administrative Borrower deems appropriate on its behalf to obtain Loans and to exercise such other powers as are reasonably incidental thereto to carry out the purposes of this Agreement. It is understood that the handling of the Loan Account and Collateral of the Borrowers in a combined fashion, as more fully set forth herein, is done solely as an accommodation to the Borrowers in order to utilize the collective borrowing powers of the Borrowers in the most efficient and economical manner and at their request, and that neither the Agent nor the Lenders shall incur liability to the Borrowers as a result hereof. Each of the Borrowers expects to derive benefit, directly or indirectly, from the handling of the Loan Account and the Collateral in a combined fashion since the successful operation of each Borrower is dependent on the continued successful performance of the integrated group. To induce the Agent and the Lenders to do so, and in consideration thereof, each of the Borrowers hereby jointly and severally agrees to indemnify the Indemnitees and hold the Indemnitees harmless against any and all liability, expense, loss or claim of damage or injury, made against such Indemnitee by any of the Borrowers or by any third party whosoever, arising from or incurred by reason of (a) the handling of the Loan Account and Collateral of the Borrowers as herein provided, (b) the Agent and the Lenders relying on any instructions of the Administrative Borrower, or (c) any other action taken by the Agent or any Lender hereunder or under the other Loan Documents.] Section 12.17 Records. The unpaid principal of and interest on the Loans, the interest rate or rates applicable to such unpaid principal and interest, the duration of such applicability, the Commitments, and the accrued and unpaid fees payable pursuant to Section 2.06 hereof shall at all times be ascertained from the records of the Agent, which shall be conclusive and binding absent manifest error. Section 12.18 Binding Effect. This Agreement shall become effective when it shall have been executed by each Loan Party, the Agent and each Lender and when the conditions precedent set forth in Section 5.01 hereof have been satisfied or waived in writing by the Agent, and thereafter shall be binding upon and inure to the benefit of each Loan Party, the Agent and each Lender, and their respective successors and assigns, except that the Loan Parties shall not have the right to assign their rights hereunder or any interest herein without the prior written consent of each Lender, and any assignment by any Lender shall be governed by Section 12.07 hereof. Section 12.19 Interest. It is the intention of the parties hereto that the Agent and each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby or by any other Loan Document would be usurious as to the Agent or any Lender under laws applicable to it (including the laws of the United States of America and the State of New York or any other jurisdiction whose laws may be mandatorily applicable to the Agent or such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in this Agreement or any other Loan Document or any agreement entered into in connection with or as security for the Obligations, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under law applicable to the Agent or any Lender that is contracted for, taken, reserved, charged or received -100-

by the Agent or such Lender under this Agreement or any other Loan Document or agreements or otherwise in connection with the Obligations shall under no circumstances exceed the maximum amount allowed by such applicable law, any excess shall be canceled automatically and if theretofore paid shall be credited by the Agent or such Lender on the principal amount of the Obligations (or, to the extent that the principal amount of the Obligations shall have been or would thereby be paid in full, refunded by the Agent or such Lender, as applicable, to the Borrowers); and (ii) in the event that the maturity of the Obligations is accelerated by reason of any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to the Agent or any Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by the Agent or such Lender, as applicable, as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by the Agent or such Lender, as applicable, on the principal amount of the Obligations (or, to the extent that the principal amount of the Obligations shall have been or would thereby be paid in full, refunded by the Agent or such Lender to the Borrowers). All sums paid or agreed to be paid to the Agent or any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable to the Agent or such Lender, be amortized, prorated, allocated and spread throughout the full term of the Loans until payment in full so that the rate or amount of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at an time and from time to time (x) the amount of interest payable to the Agent or any Lender on any date shall be computed at the Highest Lawful Rate applicable to the Agent or such Lender pursuant to this Section 12.19 and (y) in respect of any subsequent interest computation period the amount of interest otherwise payable to the Agent or such Lender would be less than the amount of interest payable to the Agent or such Lender computed at the Highest Lawful Rate applicable to the Agent or such Lender, then the amount of interest payable to the Agent or such Lender in respect of such subsequent interest computation period shall continue to be computed at the Highest Lawful Rate applicable to the Agent or such Lender until the total amount of interest payable to the Agent or such Lender shall equal the total amount of interest which would have been payable to the Agent or such Lender if the total amount of interest had been computed without giving effect to this Section 12.19. For purposes of this Section 12.19, the term "applicable law" shall mean that law in effect from time to time and applicable to the loan transaction between the Borrowers, on the one hand, and the Agent and the Lenders, on the other, that lawfully permits the charging and collection of the highest permissible, lawful non-usurious rate of interest on such loan transaction and this Agreement, including laws of the State of New York and, to the extent controlling, laws of the United States of America. The right to accelerate the maturity of the Obligations does not include the right to accelerate any interest that has not accrued as of the date of acceleration. Section 12.20 Confidentiality. The Agent and each Lender agrees (on behalf of itself and each of its affiliates, directors, officers, employees and representatives) to use reasonable precautions to keep confidential, in accordance with its customary procedures for handling confidential information of this nature and in accordance with safe and sound practices of comparable commercial finance companies, any non-public information supplied to it by the Loan Parties pursuant to this Agreement or the other Loan Documents which is identified in writing by the Loan Parties as being confidential at the time the same is delivered to such Person -101-

(and which at the time is not, and does not thereafter become, publicly available or available to such Person from another source not known to be subject to a confidentiality obligation to such Person not to disclose such information), provided that nothing herein shall limit the disclosure of any such information (i) to the extent required by statute, rule, regulation or judicial process, (ii) to counsel for the Agent or any Lender, (iii) to examiners, auditors, accountants or Securitization Parties, (iv) in connection with any litigation to which the Agent or any Lender is a party or (v) to any assignee or participant (or prospective assignee or participant) so long as such assignee or participant (or prospective assignee or participant) first agrees, in writing, to be bound by confidentiality provisions similar in substance to this Section 12.20. The Agent and each Lender agrees that, upon receipt of a request or identification of the requirement for disclosure pursuant to clause (iv) hereof, it will make reasonable efforts to keep the Loan Parties informed of such request or identification; provided that the each Loan Party acknowledges that the Agent and each Lender may make disclosure as required or requested by any Governmental Authority or representative thereof and that the Agent and each Lender may be subject to review by Securitization Parties or other regulatory agencies and may be required to provide to, or otherwise make available for review by, the representatives of such parties or agencies any such non-public information. Section 12.21 Integration. This Agreement, together with the other Loan Documents, reflects the entire understanding of the parties with respect to the transactions contemplated hereby and shall not be contradicted or qualified by any other agreement, oral or written, before the date hereof.

Any LC Disbursement remaining unpaid after demand therefor (or during continuance of an Event of Default described in clauses (e) or (f) of Paragraph 21 below) shall accrue interest, from and including the date on which such LC Disbursement arose through, but excluding, the date on which such LC Disbursement is paid in full in cash, at a rate per annum equal to LIBOR plus one half of one percent (.50%). The Applicant hereby irrevocably waives the right to direct the application of any and all payments in respect of LC Disbursements received from or on behalf of the Applicant, and the Applicant hereby irrevocably agrees that the Bank shall have the continuing exclusive right to apply any and all such payments as the Bank may deem advisable. 4

6. Obligations Absolute. The obligation of the Applicant to reimburse the Bank for payments made with respect to any Letter of Credit shall be absolute, unconditional and irrevocable, without necessity of presentment, demand, protest, or other formalities. Such obligations of the Applicant shall be paid strictly in accordance with the terms hereof under all circumstances, including the following circumstances: (a) any lack of validity of enforceability of this Agreement, any Letter of Credit, any other Credit Document or any term or provision contained in any thereof; (b) the existence of any claim, set-off, defense or other right which Applicant may at any time have against a beneficiary or any transferee of any Letter of Credit (or any persons or entities for whom any such transferee may be acting), the Bank or any other person, whether in connection with this Agreement, any Letter of Credit, or any transaction in connection with any Letter of Credit (including any underlying transaction between the Applicant and the beneficiary for which the Letter of Credit was procured); (c) any draft, demand, certificate or any other document presented under any Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; (d) payment by the Bank under any Letter of Credit against presentation of a demand, draft or certificate or other document which substantially complies, but does not strictly comply, with the terms of such Letter of Credit; (e) the fact that an Event of Default shall have occurred and be continuing; or (f) any other event, circumstances or happening whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Paragraph 6, constitute a legal or equitable discharge of the Applicant's obligations hereunder. 7. Applicant's Assumption of Risk. As between the Bank and the Applicant, the Applicant assumes all risks relating to the acts and omissions of, or the misuse of any Letter of Credit by, the beneficiaries of any Letter of Credit. In furtherance and not in limitation of the foregoing, to the fullest extent permitted by law, the Bank shall not be responsible: (a) for the form, validity, sufficiency, accuracy, genuineness or legal effect of any document issued by any party in connection with the application for and issuance of any Letter of Credit, even if such document shall prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged; (b) for the validity, efficacy or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any Letter of Credit or the rights and benefits thereunder or the proceeds thereof, in whole or in part; (c) for failure of the beneficiary of any Letter of Credit to comply fully with conditions required in order to demand payment under such Letter of Credit; (d) for errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise, whether or not they be in cipher; (e) for errors in interpretation of technical terms; (f) for any loss or delay in the transmission or otherwise of any document required in order to make a payment under any Letter of Credit or of the proceeds thereof; (g) for the use of the proceeds of any drawing under any Letter of Credit; and (h) for any consequences arising from causes beyond the control of the Bank. None of the above shall 5

affect, impair or prevent the vesting of any of the rights or powers of the Bank hereunder. Nothing contained herein shall be deemed to limit any waiver, covenants or indemnities made by the Applicant in favor of the Bank in any letter of credit application, reimbursement agreement or similar document, instrument or agreement between the Applicant and the Bank. 8. Indemnity Relating to Letters of Credit.

Governing Law, Etc., of Letters of Credit. All Letters of Credit issued hereunder shall be subject to the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce, Publication No. 500 ("UCP") (and any subsequent amendments or revisions thereof) or the International Standby Practices ("ISP") International Chamber of Commerce, Publication No. 590 (and any subsequent amendments and revisions thereof), as applicable, and as to matters not governed by UCP or ISP, shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts and applicable U.S. Federal law. 10. Expiration of Commitment. Unless previously terminated, the LC Commitment shall expire at the close of business on the Commitment Termination Date. 11. Permitted Uses. The Letters of Credit will be used only for general corporate and working capital purposes of the Applicant. 12. Security. (a) As security for the full payment, performance and discharge of the Obligations, the Applicant hereby delivers and pledges to the Bank and grants to the Bank a first priority lien upon and continuing security interest in the Collateral. To the extent the Bank receives payment on account of the Obligations, which payment is thereafter set aside or required to be repaid by the Bank in whole or in part, then, to the extent of any sum not finally retained by the Bank (regardless of whether such sum is recovered from the Bank by the Applicant, or the Applicant's estate or trustee or any party acting for, on behalf of or through the Applicant as the Applicant's representative), the Obligations shall be reinstated and the lien and security interest created hereby shall remain in full force and effect (or be reinstated) until the Applicant shall have made payment to the Bank, which payment shall be due on demand. 6

(b) Except for the security interest created hereunder (and the subordinated second priority security interest granted by the Applicant in favor of Ableco), the Applicant is the owner of the Collateral free from any lien or security interest. The Applicant agrees not to grant any lien on or security interest in, or permit the existence of any lien on or security interest in, the Collateral Account or any of the other Collateral (except in favor of the Bank, and except for the subordinated second priority security interest in favor of Ableco). (c) The Applicant will promptly execute and deliver to the Bank such financing statements, certificates and other documents or instruments as may be necessary to enable the Bank to perfect, protect or from time to time renew the security interest granted hereby, including, without limitation, such financing statements, control agreements, certificates and other documents as may be necessary to perfect a security interest in any additional Collateral hereafter acquired by the Applicant or in any replacements or proceeds thereof. The Applicant authorizes the Bank to file and refile (at the Applicant's expense) such financing statements, continuation statements and other documents (including, without limitation, this Agreement) in such offices as the Bank may reasonably deem necessary or appropriate in order to perfect and preserve the rights and interests granted to the Bank hereunder, and agrees that it will join with the Bank in executing any such financing statements, continuation statements or other documents as the Bank may reasonably deem necessary. The Applicant authorizes and appoints the Bank, in case of need, to execute such financing statements, assignments, certificates and other documents pertaining to the Bank's security interest in the Collateral in its stead if the Applicant fails to so execute such documents, with full power of substitution, as the Applicant's attorney in fact. (d) Provided no Default or Event of Default shall have occurred or be continuing or shall arise therefrom, unless Ableco has notified the Bank that an event of default has occurred and is continuing under the Ableco Financing Agreement, on the fifteenth day of each calendar month (or, if such day is not a Business Day, on the next succeeding Business Day), commencing on October 15, 2002, the Bank shall withdraw from the Collateral Account the aggregate amount of interest that has accrued on the funds on deposit in the Collateral Account during the prior month and shall transfer such interest to the Applicant in accordance with the wire instructions of the Applicant set forth on Schedule I hereto (whereupon such interest shall no longer be subject to the security interest granted to the Bank hereunder). Upon any such disbursement, the Applicant shall be deemed to have represented to the Bank that both immediately before and immediately after giving effect to such disbursement, no Default or Event of Default shall have occurred and be continuing. (e) Provided no Default or Event of Default shall have occurred or be continuing or shall arise therefrom, from time to time (but not more frequently than once in any calendar month) after the earlier of (i) 3 Business Days after the last day of the Availability Period and (ii ) the Commitment Termination Date, upon the written request of Ableco, the Bank shall withdraw from the Collateral Account the amount, if any, by which (x) the aggregate amount of funds on deposit in the Collateral Account (exclusive of interest amounts referred to in clause (d) above) exceeds (y) the product of (A) one hundred three percent (103%) multiplied by (B) the LC Exposure at such time, and shall transfer such excess amount to Ableco in accordance with the wire transfer instructions of Ableco set forth on Schedule I hereto to be applied by Ableco against the Applicant's obligations to Ableco (whereupon such excess amount 7

shall no longer be subject to the security interest granted to the Bank hereunder). Upon any such disbursement, the Applicant shall be deemed to have represented to the Bank both immediately before and immediately after giving effect to such disbursement no Default or Event of Default shall have occurred and be continuing. (f) The Applicant shall have no right to request or receive disbursements from the Collateral Account, except as provided in clauses (d) and (e) of this Paragraph 12. The Applicant hereby irrevocably authorizes and directs the Bank to make the transfers described in clauses (d) and (e) of this Paragraph 12, and hereby agrees that in no event shall the Bank be liable or obligated to the Applicant for any transfer made in accordance with such clauses, or for any failure by the Bank to make any such transfer if the Bank, in its reasonable determination, believes that a Default or Event of Default has occurred and is continuing under this Agreement or the Credit Documents, or that such transfer may expose the Bank to any obligation, liability or expense (other than any administrative costs and expenses related to or incurred in connection with the transfers described in clauses (d) and (e) of this Paragraph 12). (g) All items of income, if any, including dividends, interest and other income, gain, expense and loss on the Collateral shall be reported by the Bank in the name and tax identification of the Applicant. (h) The Applicant acknowledges and agrees that, regardless of the adequacy of the Collateral or any other security for the Obligations, the Bank may withdraw from the Collateral Account at any time and from time to time (whether before or after the occurrence of an Event of Default) and apply such funds as may be necessary (i) to reimburse the Bank for any drawing made on any Letter of Credit, and (ii) to cover any fees, costs, expenses (including reasonable attorney's fees) and other amounts for which the Applicant may from time to time be liable to the Bank. (i) In addition to the Bank's rights under the foregoing clause (h), upon the occurrence and during the continuance of any Event of Default, the Bank shall have the right at any time and from time to time without the necessity of making demand upon or giving notice to the Applicant (i) to withdraw funds from the Collateral Account and apply such funds to the repayment of the then unpaid amount of all Obligations, (ii) to set-off the funds in the Collateral Account and any deposits or other sums at any time credited thereto against the Obligations, and (iii) to exercise any and all rights and remedies of a secured party under the Uniform Commercial Code (as in effect in Massachusetts), including, without limitation, the rights of a secured party under Section 9-607 of the Uniform Commercial Code. The Applicant hereby waives presentment, demand, notice, protest and all other demands and notices in connection with this Agreement or the enforcement of the Bank's rights hereunder or in connection with any of the Obligations. (j) In the event that the Bank elects to exercise any of its remedies with respect to the Collateral following an Event of Default, the Bank shall apply the proceeds of the Collateral as follows: (i) first, to the payment of any and all fees, costs and expenses incurred by the Bank in exercising its rights (including, without limitation, reasonable attorney's fees), and (ii) second, to the repayment of any and all Obligations then due and payable, and (iii) third, to the extent any Obligations have yet to mature or become due and payable at the time the Bank 8

exercises its rights with respect to the Collateral, the Bank shall hold such proceeds as collateral for, and shall apply such proceeds to, the repayment of any remaining Obligations as and when the same shall become due and payable. In the event the proceeds of the Collateral are insufficient to pay all of the Obligations in full, the Applicant shall be liable for the deficiency, together with interest thereon at a rate per annum equal to LIBOR plus one half of one percent (.50%), and the cost and expenses of collection of such deficiency, including (to the extent permitted by law), without limitation, reasonable attorneys' fees, expenses and disbursements. (k) If, following the repayment of all of the Applicant's Obligations, the termination and/or expiration of all Letters of Credit issued hereunder, and the termination of the LC Commitment, there shall remain any surplus Collateral in the Collateral Account, such surplus shall be paid to the Applicant (or to any person or party lawfully entitled thereto (including, if applicable, Ableco or any other subordinated creditor of the Applicant). In exercising any rights with respect to the Collateral, so long as the Bank acts in a commercially reasonable manner, the Bank may proceed in any manner which the Bank, in its sole discretion, shall elect, without in any way incurring any liability or obligations to the Applicant. 13. Fees and Charges. The Applicant agrees to pay the Bank's customary commissions, discounts, interest, charges, fees or expenses (collectively, "Bank Charges") in connection with the issuance, amendment, extension or renewal of any Letter of Credit and any drawings thereunder. Bank Charges shall be payable monthly in arrears, on the first day of each month and on the Maturity Date. The Applicant further agrees to pay to the Bank, as compensation for issuing the Letters of Credit hereunder and for all services which the Bank may render hereunder, a per annum letter of credit fee equal in amount to three tenths of one percent (.30%) multiplied by the face amount of all outstanding Letters of Credit ("Fees"). Such Fees shall be payable quarterly in advance, on the first day of each calendar quarter and on the Maturity Date. Fees and Bank Charges paid shall not be refundable under any circumstances, absent manifest error in the determination thereof. Bank Charges and Fees which are not paid when due shall accrue interest at a rate per annum equal to LIBOR plus one half of one percent (.50%) from the due date through the date of payment and shall be payable on demand. In the event that any Bank Charges and Fees are not paid when due, the Bank may, at its own election, effect payment of such Bank Charges and/or Fees and any interest due thereon by withdrawing an amount equal thereto from the Collateral Account, and the Applicant hereby irrevocably authorizes and directs the Bank to take any and all action necessary to effectuate such withdrawal. 14. General Indemnification. The Applicant agrees to pay all costs and expenses (including the reasonable fees and disbursements of counsel) incurred by the Bank in connection with the creation and enforcement of this Agreement and the other Credit Documents and the collection of all amounts payable hereunder and thereunder.

Bank's security interest in or lien on any of the Collateral, whether through judicial proceedings or otherwise, (d) in defending or prosecuting any actions or proceedings arising out of or relating to the transactions of the Bank with the Applicant, and (e) in connection with any advice given to the Bank with respect to its rights and obligations under this Agreement, the Letters of Credit or any other Credit Documents, shall all be part of the Obligations secured by the Collateral. The Applicant shall indemnify the Bank and its officers, directors, affiliates, employees and agents (which indemnity shall survive the termination of this Agreement) from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of any kind or nature whatsoever (including, without limitation, reasonable fees and disbursements of counsel) which may be imposed on, incurred by, or asserted against any such indemnified party in any litigation, proceeding or investigation (including any limitation, any proceeding or investigation arising out of any environmental laws) instituted or conducted by any governmental agency or instrumentality or any other person or entity in connection with any Letter of Credit, or any transaction contemplated by, or referred to in, or any matter related to, this Agreement or any other Credit Document, whether or not the Bank is a party thereto, except to the extent that any of the foregoing arises out of the gross negligence or willful misconduct of such indemnified party (as determined by a court of competent jurisdiction by final and non-appealable judgment). 15. Taxes. Each payment hereunder shall be made free and clear of, and without deduction or withholding for, any taxes, duties, levies, imposts or other charges of a similar nature other than taxes on overall net income or receipts and franchise taxes (imposed in lieu of net income taxes) ("Taxes"), except as required by law, and in the event that any deduction or withholding for Taxes shall be so required, the Applicant shall pay such additional amounts as may be necessary so that the net amount of such payment, after reduction by the amount of such Taxes, is equal to the amount that the Applicant is obligated to pay absent the requirement to deduct such Taxes. 16.

interests granted to Fleet and Ableco. The Pledgor hereby irrevocably appoints each of Fleet and Ableco as its true and lawful attorney for the purpose of executing and filing any such financing statements or other agreements or instruments. 4. Control over the Collateral Account and the Collateral; Subordination of Rights and Interests of Ableco. Each of the parties hereto hereby acknowledges and agrees as follows: (a) Unless and until such time as Fleet shall have delivered a Termination Notice to the Pledgor and Ableco, (i) Fleet has and shall continue to have "control" of the Collateral Account and the Collateral (within the meaning of such term under Section 9-104 of the Uniform Commercial Code as in effect in The Commonwealth of Massachusetts) and full power and authority to set-off, apply, debit, withdraw, dispose of and transfer funds from the Collateral Account without the necessity of notifying or obtaining the consent of the Pledgor or Ableco, (ii) except as otherwise provided in Sections 4(e), 6(a) and 6(b) of this Agreement, Fleet shall not be obligated to comply with, and shall have no liability to the Pledgor or Ableco for refusing to comply with, any instructions originated by the Pledgor or Ableco with respect to the Collateral Account or the Collateral, including, without limitation, any instructions or directions with respect to the disposition of funds in the Collateral Account, (iii) regardless of the time, order or manner of attachment or perfection, or any provision of the Ableco Documents to the contrary, the rights and interests of Fleet in and to the Collateral Account and the Collateral have and shall continue to have priority over and shall be senior in all respects to any rights or interests of Ableco in and to the Collateral Account and the Collateral, and (iv) it is the intent of the parties hereto that, except as otherwise provided in Section 6(b), Termination of the Fleet Obligations shall have occurred before any portion of the Collateral is delivered to Ableco or applied to the Ableco Obligations. (b) Until such time as the Ableco Obligations have been paid in full and the Ableco Financing Agreement shall have terminated, (i) Ableco has and shall continue to have "control" of the Collateral Account and the Collateral (within the meaning of such term under Section 9-104 of the Uniform Commercial Code as in effect in The Commonwealth of Massachusetts) and shall be able to direct the disposition of funds from the Collateral Account without the necessity of notifying or obtaining the consent of the Pledgor, and (ii) except as otherwise provided in Section 6(a), Fleet will comply with all notifications it receives directing it to transfer, redeem, or permit the withdrawal of any property in the Collateral Account originated by Ableco without further consent by the Pledgor; provided that, unless and until such time as Fleet shall have delivered a Termination Notice to Ableco, Ableco shall not, except as otherwise provided in Section 6(b), direct or instruct Fleet to take any action with respect to the Collateral Account or the Collateral or otherwise assert or attempt to enforce or avail itself of any lien or security interest in the Collateral or otherwise realize upon the Collateral, and, except as otherwise provided in Section 6(b), Fleet shall not be obligated to comply with any direction or instruction originated by Ableco with respect to the Collateral Account or the Collateral, including, without limitation, any instruction or direction regarding the disposition of funds in the Collateral Account. (c) Unless and until such time as (i) Fleet shall have delivered a Termination Notice to the Pledgor, and (ii) the Ableco Obligations have been repaid in full and the Ableco Financing Agreement has terminated, the Pledgor shall have no right to access or withdraw any of the Collateral from the Collateral Account or to instruct or direct Fleet to make withdrawals from or transfer or dispose of any funds in the Collateral Account; and Fleet shall not, except as otherwise provided in Section 6(a), comply with any withdrawal request, direction or instruction originated by the Pledgor with respect to the Collateral Account and the Collateral unless Ableco has previously consented to such withdrawal request, direction or instruction in writing and notified Fleet to comply with same. Promptly, but in any event within 3 business days after Termination of the Fleet Obligations, Fleet shall deliver the Termination Notice to the Pledgor and Ableco. (d) Notwithstanding anything in this Agreement or in the Ableco Documents to the contrary, (i) the respective rights and priorities of the liens and security interests of Fleet and Ableco set forth herein shall not be altered, impaired or affected in any way by any amendment, modification, supplement to or restatement of the Fleet Documents, any increase in Fleet's LC Commitment or in Fleet's LC Exposure, any application of the Collateral against the Fleet Obligations, or any release or reduction in the amount of the Collateral (and Fleet expressly reserves the right, prior to the delivery of a Termination Notice to Ableco, to amend, modify, supplement or restate the Fleet Documents, to increase Fleet's LC Commitment, to apply the Collateral against the Fleet Obligations, or to release all or any portion of the Collateral, without the necessity of giving notice to or obtaining the consent of Ableco), and (ii) until such time as Fleet shall have delivered a Termination Notice to the Pledgor and Ableco, except as otherwise provided in Section 6(b), Fleet shall at all times be authorized to, and shall act and refrain from acting in respect of, and otherwise deal with, the Collateral and the Collateral Account, in its sole and absolute discretion, without any obligation whatsoever on the part of Fleet to notify or obtain the consent of the Pledgor or Ableco. (e) At the time of delivery by Fleet to the Pledgor and Ableco of a Termination Notice, the liens and security interests of Fleet in the Collateral and the Collateral Account shall automatically be released, discharged and terminated and Fleet shall, at the request of Ableco, or at the election of Fleet (which election may be made by Fleet at any time in its sole discretion), cause (and the Pledgor hereby authorizes and directs Fleet to cause) any remaining Collateral in the Collateral Account to be 3

delivered to Ableco (or to a depository institution specified in writing by Ableco), to be held by or for the benefit of Ableco as security for the Ableco Obligations of Ableco and the Lenders. (f) If at any time Fleet shall exercise any of its rights with respect to the Collateral (including, the right to apply any portion of the Collateral against the Fleet Obligations or to set-off, foreclose, liquidate or otherwise realize upon any portion of the Collateral), Fleet shall apply the proceeds of the Collateral and the Collateral Account as follows: (i) first, to the payment of any and all fees, costs and expenses incurred by Fleet in exercising its rights (including, without limitation, reasonable attorney's fees), and (ii) second, to the repayment of any and all Fleet Obligations. If, following Termination of the Fleet Obligations, there shall remain any surplus Collateral in the Collateral Account which would otherwise, but for the security interest of Ableco, be payable to the Pledgor, Fleet shall, unless directed otherwise by a court of competent jurisdiction or by Ableco, deliver such surplus Collateral to Ableco (or to a depository institution specified in writing by Ableco) to be held by or for the benefit of Ableco and the Lenders as collateral for and/or applied to the repayment of the Ableco Obligations in accordance with the terms of the Ableco Documents. In exercising any rights with respect to the Collateral, so long as Fleet acts in a commercially reasonable manner, Fleet may proceed in any manner which Fleet, in its sole discretion, shall elect, without in any way incurring any liability or obligations to the Pledgor or Ableco. Except as otherwise expressly set forth in Section 6 of this Agreement, in no event shall Fleet be obligated to deliver any portion of the Collateral to the Pledgor or Ableco unless and until such time as Termination of the Fleet Obligations has occurred. (g) In the event that Fleet shall exercise any of its rights with respect to the Collateral under the Fleet Documents or under the provisions of any applicable law (including, without limitation, the right of set-off), any portion of the Collateral applied to the repayment of the Fleet Obligations shall automatically be released and Ableco shall have no rights, claims or interests against Fleet or against such portion of the Collateral. Ableco agrees that promptly upon the written request of Fleet therefor, Ableco shall execute, deliver and file any and all such termination statements, lien releases or other agreements or instruments as Fleet shall reasonably deem necessary or appropriate in order to give effect to the foregoing provisions of this Section 4(g). 5. Application, Set-off and other Rights of Fleet. The Pledgor and Ableco acknowledge and agree that under the terms of the Fleet Documents and applicable law, regardless of the adequacy of the Collateral or any other property or collateral securing the Fleet Obligations, Fleet (a) may withdraw and apply from the Collateral Account at any time and from time to time such funds as may be necessary (i) to reimburse Fleet for any drawing made on any letter of credit issued by Fleet under the terms of the Fleet Documents, and (ii) to cover any fees, costs, expenses (including reasonable attorney's fees)and other amounts for which the Pledgor may from time to time be liable to Fleet under the terms of the Fleet Documents, (b) may set-off the Collateral and the Collateral Account and any deposits or other sums at any time credited thereto against the Fleet Obligations, and (c) has all rights and remedies of a secured party under the Uniform Commercial Code (as in effect in Massachusetts), including, without limitation, the rights of a secured party under Section 9-607 of the Uniform Commercial Code. In no event shall the liens, rights and interests of Ableco, or any term or provision of this Agreement, impair or affect in any way any rights or remedies (including, without limitation, any rights of set off) that Fleet may have against the Pledgor, the Collateral Account, the Collateral or any other property or assets of the Pledgor prior to the date on which Fleet delivers the Termination Notice to the Pledgor and Ableco. 6. Periodic Withdrawals from the Collateral Account. The Pledgor and Ableco acknowledge and agree that pursuant to the terms of the Fleet Documents so long as no Default or Event of Default (as such term is defined in the Fleet Documents on the date hereof) shall have occurred and be continuing or shall arise therefrom: (a) unless Ableco has notified Fleet that an event of default has occurred and is continuing under the Ableco Financing Agreement, on the fifteenth day of each calendar month (or if such day is not a business day, on the next succeeding business day), commencing on October 15, 2002, Fleet shall withdraw from the Collateral Account the aggregate amount of interest that has accrued on the funds on deposit in the Collateral Account during the prior month, and shall transfer such interest to Pledgor in accordance with the wire transfer instructions of the Pledgor set forth on Schedule I hereto (whereupon such interest shall no longer be subject to the liens and security interests of Fleet or Ableco); and (b) from time to time (but not more frequently than once each month) after the earlier of (x) 3 Business Days after the date on which Fleet's LC Commitment terminates, and (y) March 31, 2003, upon the written request of Ableco, Fleet shall withdraw from the Collateral Account the amount, if any, by which (i) the aggregate amount of funds on deposit in the Collateral Account (exclusive of the interest amounts referred to in Section 6(a)) exceeds (ii) the product of (A) one hundred three percent (103%) multiplied by (B) Fleet's LC Exposure at such time, and shall transfer such excess amount to Ableco in accordance with the wire transfer instructions of Ableco set forth on Schedule I hereto to be applied by Ableco against the Ableco Obligations (whereupon such excess amount shall no longer be subject to the liens and security interests of Fleet). 4

Each of the Pledgor and Ableco hereby irrevocably authorize and direct Fleet to make the transfers described in this Section 6, and hereby agree that in no event shall Fleet be liable or obligated to the Pledgor or Ableco for any transfer made in accordance with this Section 6, or for any failure by Fleet to make any such transfer if Fleet, in its reasonable determination, believes that a Default or Event of Default has occurred and is continuing under the Fleet Documents, or that such transfer may expose Fleet to any obligation, liability or expense (other than any administrative costs and expenses related to or incurred in connection with the transfers described in this Section 6). 7. No Consent Required; Authority of Fleet to Act. Notwithstanding any separate agreement that the Pledgor may have with Ableco or any other party, the Pledgor and Ableco acknowledge and agree that unless and until such time as Fleet shall have delivered a Termination Notice to the Pledgor and Ableco, Fleet shall be authorized and directed to take such actions with respect to the Collateral and the Collateral Account as Fleet, in its sole discretion, determines to be necessary, appropriate or in the best interests of Fleet (including, without limitation, exercising any rights of set-off which Fleet may have with respect to the Collateral or the Collateral Account), in each case, without the necessity of giving prior notice to, or obtaining any consent from, the Pledgor or Ableco. 8. Standard of Care. Neither Fleet nor any of its officers, directors, employees, agents or affiliates shall be liable for any action taken or not taken by it under, or in connection with, this Agreement, except for gross negligence or willful misconduct by Fleet as determined by a final and non-appealable judgment of a court of competent jurisdiction. IN NO EVENT SHALL FLEET BE LIABLE FOR INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES OF ANY KIND WHATSOEVER (INCLUDING LOST PROFITS AND LOST BUSINESS OPPORTUNITIES) EVEN IF IT IS INFORMED OF THE POSSIBILITY OF SUCH DAMAGES AND REGARDLESS OF THE FORM OF ACTION IN WHICH ANY SUCH DAMAGES MAY BE CLAIMED. SO LONG AS FLEET SHALL HAVE ACTED (OR REFRAINED FROM ACTING) IN GOOD FAITH, IT SHALL NOT BE LIABLE FOR ANY ERROR OF JUDGMENT IN ANY ACTION TAKEN, SUFFERED OR OMITTED BY, OR FOR ANY MISTAKE OF FACT OR LAW, UNLESS SUCH ACTION IS FOUND TO CONSTITUTE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT BY A FINAL AND NON-APPEALABLE JUDGMENT OF A COURT OF COMPETENT JURISDICTION. Fleet will not incur any liability hereunder by acting or not acting in reliance upon any notice, consent, certificate, statement or other instrument or writing believed by it to be genuine and signed or sent by the proper party or parties. Fleet shall not incur liability hereunder for any notice, consent, certificate, wire instruction, telecopy, or other writing which is delayed, canceled or changed without the actual knowledge of Fleet. Fleet shall not incur any liability for acts or omissions of any domestic or foreign depository or book-entry system for the central handling of financial assets or any domestic or foreign custodian or subcustodian. Fleet shall not be responsible for the title, value, validity or genuineness of any Collateral subject to this Agreement. Fleet shall have no liability to the Pledgor or any other person or entity for remitting any portion of the Collateral in the Collateral Account to Ableco after the delivery by Fleet of a Termination Notice even if contrary instructions have been delivered to Fleet by the Pledgor and Fleet shall have no duty to investigate whether and to what extent any Ableco Obligations shall then be outstanding. 9. No Additional Duties. Fleet shall have no responsibilities, obligations or duties other than those expressly set forth in this Agreement, and no implied duties, responsibilities or obligations shall be read into this Agreement; without limiting the foregoing, Fleet shall have no duty to preserve, exercise or enforce rights in the Collateral (against prior parties or otherwise). This Agreement is not intended by the parties to impose or create any obligations or duties upon Fleet greater than, or in addition to, the customary and usual obligations and duties of Fleet to the Pledgor, except as otherwise provided in Section 6. The Pledgor and Fleet acknowledge that this Agreement supplements the Pledgor's existing cash management and other relationships with Fleet and in no way is this Agreement intended to abridge any rights that Fleet might otherwise have under the Fleet Documents or applicable law. Fleet makes no representations and assumes no responsibility as to the validity, enforceability or perfection, if any, of Ableco's purported liens and security interests in the Collateral, other than Fleet's obligation to act in accordance with the material terms of this Agreement. 10. Force Majeure. Fleet shall not be responsible for delays or failures in performance resulting from acts beyond its control, including Acts of God, strikes, lockouts, riots, acts of war or terrorism, epidemics, nationalization, expropriation, currency restrictions, governmental regulations superimposed after the fact, fire, communication line failures, power failures, earthquakes or other disasters. 11. Release and Indemnification. The Pledgor and Ableco hereby release Fleet and its respective affiliates, officers and employees from any and all claims, causes of action, liabilities, losses, lawsuits, recoupment, demands and/or damages, fines, penalties and expenses that may arise as a result of the transactions contemplated by this Agreement or as a result of Fleet entering into or acting in accordance with this Agreement, making any transfers of funds contemplated by this Agreement, or 5

following any instructions given to Fleet by Ableco or the Pledgor in accordance with the terms of this Agreement, except for proven gross negligence or willful misconduct by Fleet. The Pledgor agrees to indemnify and hold harmless Fleet and its respective affiliates, officers and employees from and against any and all claims, causes of action, liabilities, losses, lawsuits, recoupment, demands and/or damages, fines, penalties and expenses, including, without limitation, out of pocket expenses and any and all court costs and reasonable attorneys' fees, that may arise as a result of Fleet entering into or taking or failing to take any action under this Agreement, making any transfers of funds contemplated by this Agreement, or following any instructions given to Fleet by Ableco or the Pledgor under this Agreement, except for gross negligence or willful misconduct by Fleet as determined by a final non-appealable judgment of a court of competent jurisdiction. This indemnification shall survive the termination of this Agreement. Ableco will indemnify Fleet, and its officers, directors, employees, and agents, against claims, liabilities, and reasonable expenses (including reasonable attorney fees and disbursements) arising out of (i) directions or instructions given by Ableco to Fleet under this Agreement, (ii) actions taken by Fleet in compliance with such directions or instructions, and (iii) transfers of funds from the Collateral Account to Ableco as provided in this Agreement, except to the extent the claims, liabilities, or expenses are caused by Fleet's gross negligence or willful misconduct as determined by a final non-appealable judgment of a court of competent jurisdiction. 12. Reporting of Income. All items of income, if any, including dividends, interest and other income, gain, expense and loss on the Collateral shall be reported by Fleet in the name and tax identification number of the Pledgor. 13. Construction; Amendment; Conflict; Entire Agreement. If any term or provision of this Agreement is determined to be invalid or unenforceable, the remainder of this Agreement shall be construed in all respects as if the invalid or unenforceable term or provision were omitted. No amendment, modification or termination of this Agreement or waiver of any right hereunder shall be binding on any party hereto unless it is in writing and is signed by the party to be charged. Each of the parties hereto intends that a facsimile transmission of a duly executed counterpart hereof shall be valid in all respects, as an original. This Agreement may be executed in any number of counterparts all of which shall constitute one original agreement. In the event of a conflict between this Agreement and any other Fleet Document, as between Fleet and the Pledgor, the terms of such other Fleet Document shall prevail; provided that if the terms of any Fleet Document relating to the Collateral Account afford the Pledgor access to or the right to withdraw funds from the Collateral Account, the terms of this Agreement shall prevail. This Agreement sets forth the entire agreement of the Pledgor, Ableco and Fleet with respect to the relative priorities of Fleet and Ableco in the Collateral, and supersedes all prior agreements (written or oral) and negotiations and all contemporaneous oral agreements concerning such subject matter and negotiations. 14. Representations and Warranties; Ableco/Fleet Covenant. Each of the parties represents and warrants that (i) it is duly incorporated or organized and is validly existing in good standing in its jurisdiction of incorporation or organization, (ii) the execution, delivery and performance of this Agreement and all documents and instruments to be delivered hereunder or thereunder have been duly authorized, (iii) the person executing this Agreement on its behalf has been duly authorized to act on its behalf, (iv) this Agreement constitutes a legal, valid, binding and enforceable agreement, and (v) entering into this Agreement will not violate any agreement, law, rule or regulation by which it is bound or by which any of its assets are affected. Ableco covenants that it shall deliver to Fleet prompt written notice of the occurrence of any Event of Default under the Ableco Financing Agreement, and Fleet covenants that it shall deliver to Ableco prompt written notice of the occurrence of any Event of Default under the Fleet Facility Agreement; provided that the failure of any party to give notice as required hereby shall not affect the relative priorities of the respective security interests of Fleet and Ableco as provided herein or the validity or effectiveness of any such notice as against the Pledgor, and provided further that neither Fleet nor Ableco shall incur any liability to any other party hereto as a result of its failure to give notice as required hereby. 15. Termination. This Agreement may be terminated by Fleet upon thirty (30) days written notice to the Pledgor and Ableco. Upon written notice from Ableco to Fleet of the repayment of the Ableco Obligations and the termination of the Ableco Financing Agreement, Ableco's security interest and lien in the Collateral shall terminate, Ableco shall have no obligation to Fleet hereunder (other than Ableco's indemnification obligations under Section 11) and Fleet shall have no further obligation to Ableco. 16. Successors and Assigns; Governing Law. This Agreement shall be binding upon and inure to the benefit of the successors and assigns (including, without limitation, any person or entity that succeeds to acquires any interest in any of the Ableco Obligations), representatives and heirs, of the respective parties hereto and shall be construed in accordance with the laws of The Commonwealth of Massachusetts (the "Governing Law State") without regard to its conflict of law principles and the rights and remedies of the parties shall be determined in accordance with such laws.

NOW, THEREFORE, in consideration of the foregoing premises and the covenants set forth below the parties agree as follow: 1. Definitions. As used in this Agreement and any Appendix hereto, the following capitalized terms shall have the meanings stated below, or as indicated elsewhere in this Agreement. "Acquisition Agreement" has the meaning set forth in the Recitals. "Alternate Facility" has the meaning set forth in Section 4. "Alternate Facility Notice" has the meaning set forth in Section 4. "Business Days" shall mean Monday through Friday excluding national holidays. "CHI" has the meaning set forth in the Preamble. "Clean Harbors" has the meaning set forth in the Preamble. "CSD" has the meaning set forth in the Recitals. "Disposal Contract" shall mean a contract or contracts mutually agreed upon by the Parties with respect to waste disposal or processing services to be provided by the Parties, in the forms attached hereto as Exhibit C and Exhibit D, as the same may be modified in writing by the Parties from time to time.

"Disposal Request" shall mean notification of a Party, either orally or in writing, of a desire by the other Party to deliver a Waste to a Facility for disposal or processing. No Disposal Request may be made until a favorable Disposal Decision has been made and an appropriate Disposal Contract shall have been executed by the Parties. 2

"Facility" shall mean any treatment, storage or disposal facility (i) that is permitted by applicable governmental authority to accept any type of Waste, (ii) which the Parties, either directly or through any subsidiary or affiliate, owns or operates, and (iii) which the Parties designate in writing on the list of Facilities. An initial list of the Clean Harbors Facilities is attached hereto as Exhibit E. An initial list of the Safety-Kleen facilities is attached hereto as Exhibit F. Conversely, the term "Facility" shall not apply, after sixty (60) days prior written notice to the other Party, to any of such Facilities which are no longer permitted to accept Waste by applicable government regulations and/or the policies and procedures of the affected Party. "Party" has the meaning set forth in the Recitals. "Parties" has the meaning set forth in the Recitals.

The term of this Agreement shall be for a period of three (3) years, commencing on the Closing Date, as defined in the Acquisition Agreement, and terminating on the third anniversary date thereof. 3. Calculation of Disposal Fees. Provided that the Party seeking payment of fees is in compliance with the terms and provisions of the respective Disposal Contracts, the fees payable by the Party obligated to pay for disposal of Waste, at any of the Facilities shall be determined in accordance with the schedule attached hereto as Exhibit G. Exhibit G will be reviewed and revised at each quarterly meeting as described in Section 16 to ensure it reflects market pricing for such disposal or processing of Wastes. 4. Disposal Commitment; Acceptance of Waste. Except as otherwise set forth in this Section 4, during the term of this Agreement each Party shall deliver the Waste listed on Exhibit A or Exhibit B, as the case may be, which it generates or handles through the BSSD or the CSD, as the case may be, for disposal, processing or treatment at the Facilities, and each Party shall accept, store, treat, process and dispose of all such Waste so delivered pursuant to this Agreement; provided, however, that the foregoing shall not prohibit or restrict either Party from utilizing an unrelated third party for disposal, processing or treatment of such Waste which is not being handled by the other Party at one of the Facilities, if such Party shall first have requested that the Waste be managed at one of the Facilities and the other Party shall either (i) notify such Party that it cannot handle or manage the particular Waste or (ii) fail to make a Disposal 3

Decision within the appropriate Disposal Decision Deadline set forth in Section 6 below. In addition, following thirty (30) days written notice (the "Alternate Facility Notice") from a disposing Party that it has identified an alternate facility (the "Alternate Facility") operated by an unrelated third party that will reduce its transportation charges for any of its Waste, such Party may dispose of such Waste at the Alternate Facility unless the other Party notifies the disposing Party within such thirty (30) day period that it will change the fees payable by the disposing Party so that the aggregate amount to be paid (including disposal fees and transportation charges) is equivalent whether such Waste is disposed of at the other Party's Facility or the Alternate Facility. Immediately after giving an Alternate Facility Notice and, in the event the other Party does not change its fees after receiving an Alternative Facility Notice, each six (6) months thereafter for the term of this Agreement, the disposing Party can be required by the other Party to produce documentation (to the extent not against any applicable law) to certify the facts set forth in such Alternate Facility Notice. If a Party initially declines to reduce its disposal fees after receiving an Alternate Facility Notice and the disposing Party utilizes the Alternate Facility described in the Alternate Facility Notice, for the remaining term of this Agreement, the Party may subsequently decide to change its disposal fees so that the aggregate amount to be paid (including disposal fees, transportation charges and any contract termination charges) is equivalent whether such Waste is disposed of at the other Party's Facility or the Alternate Facility, in which case, the disposing Party must begin utilizing the other Party's Facility to dispose of such Waste. Notwithstanding anything to the contrary contained herein, CHI will not be required to deliver Waste of certain of its customers to the extent that such customers restrict the locations where such Waste may be handled to locations which do not include any of Safety-Kleen's Facilities. 5. Waste Profiles. For the term of this Agreement, each Party may utilize the waste profile sheets currently established and on file for Waste presently originating from the BSSD, the CSD or directly from its respective customers; provided, however, each Party reserves the right to require periodic recertification (including, a representative sample of Waste) of any Waste stream for which a waste profile sheet is currently maintained, and such other recertification as may be required by the requesting Party's policies and procedures or by government regulations. 6. Disposal Decision and Disposal Request Deadlines. Each Party shall render Disposal Decisions on Waste offered for disposal or processing by the other Party in accordance with the following schedule: (a) for Disposal Decisions that require the receiving Party to perform laboratory analysis, a decision will be rendered and communicated within ten (10) Business Days from receiving a complete Waste profile sheet and sample, and (b) for Disposal Decisions for which the shipping Party has provided the laboratory analysis in accordance with Section 5, or for which laboratory analysis is not required, a Disposal Decision will be rendered and communicated within three (3) Business Days from receipt of completed paperwork. Each Party shall communicate a scheduled delivery date within two (2) Business Days after a Disposal Request is received from the other Party. 7. Termination of Disposal. In the event that either Party decides or is required by law to cease accepting a Waste at a Facility for which a waste profile sheet then exists, the other Party shall be given thirty (30) days advance written notice thereof, provided that in the event 4

that the affected Party is obligated to cease accepting a Waste due to a force majeure event, as defined below, this notice provision shall not apply. During any period when a Party ceases to accept a particular Waste pursuant to this Section 7, or is otherwise unable or unwilling to render services for any reason, shall be authorized to contract with competitors of the Party unable or unwilling to accept the Waste on such terms as may be necessary to dispose of such particular Waste. 8. Other Obligations of the Parties. Each Party may impose a late charge of up to one and one-half percent (1-1/2%) per month on amounts due under a Disposal Contract not paid in full within thirty (30) days after the date of the invoice. Except as superceded by the terms of this Agreement, delivery by a Party of Waste to the Facilities and disposal or processing of said Waste at such Facilities shall be pursuant, where applicable, to the terms of the Disposal Contracts, and any inconsistency between this Agreement and the Disposal Contracts shall be resolved in favor of and governed by this Agreement. 9. Indemnification by Clean Harbors. Clean Harbors shall indemnify, defend and save harmless Safety-Kleen, and its subsidiary companies and its affiliates, and their present and future officers or directors (or officials), employees and agents, from and against any and all liabilities, penalties, fines, forfeitures, demands, claims, causes of action, suits, and costs and expenses incidental thereto (including cost of defense, settlement, and reasonable attorneys' fee), which any or all of them may hereafter suffer, incur, be responsible for or pay out as a result of bodily injuries (including death) to any person, damage (including loss of use) to any property (public or private), contamination of or adverse effects on the environment, or any violation or alleged violation of statutes, ordinances, orders, rules or regulations of any governmental entity or agency, to the extent caused by (i) the breach of any warranties by Clean Harbors, or (ii) any negligent or willful act or omission of, or the breach of any environmental law by Clean Harbors, its employees or its subcontractors in the performance of this Agreement, except to the extent of the indemnification by Safety-Kleen provided for in Section 10 hereof. 10. Indemnification by Safety-Kleen. Safety-Kleen shall indemnify and save harmless Clean Harbors and its affiliates, and its present and future officers or directors (or officials), employees and agents, from and against any and all liabilities, penalties, fines, forfeitures, demands, claims, causes of action, suits, and costs and expenses incidental thereto (including cost of defense, settlement, and reasonable attorneys' fees), which any or all of them any hereafter suffer, incur, be responsible for or pay out as a result of bodily injuries (including death) to any person, damage (including loss of use) to any property (public or private), contamination of or adverse effects on the environment, or any violation or alleged violation of statutes, ordinances, orders, rules or regulations of any governmental entity or agency, to the extent caused by(i) the breach of any warranties by Safety-Kleen, or (ii) any negligent or willful act or omission of, or the breach of any environmental law by Safety-Kleen, its employees or its subcontractors in the performance of this Agreement, except to the extent of the indemnification by Clean Harbors provided for in Section 9 hereof. 11. Indemnification Procedures. The Party seeking indemnification (indemnitee) shall give written notice to the indemnifying party (indemnitor) of a claim for indemnification within a reasonable time following indemnitee's first knowledge of the event or occurrence which gives rise to that claim. Upon receipt of notice, indemnitor shall have the right to certain counsel to 5

defend, negotiate, adjust and/or settle a claim against indemnitee and indemnitor will pay reasonable attorneys' fees and other litigation expenses; provided, however, if indemnitor affirms its obligations to indemnify indemnitee with respect to a specific claim with counsel reasonably acceptable to indemnitee, then indemnitor shall thereafter not be responsible for the payment of legal fees for indemnitee's counsel and indemnitee may continue to have its counsel participate in any legal proceedings at indemnitee's sole cost and expense. Indemnitor has no obligation to indemnify indemnitee to the extent indemnitee fails to provide timely notice of a claim and such failure materially prejudices indemnitor's ability to defend, negotiate, adjust and/or settle the claim. Notwithstanding the foregoing or anything herein to the contrary, indemnitor shall not settle a claim against indemnitee without indemnitee's prior written approval. In no event shall either Party be liable to the other Party for any punitive, special, indirect, incidental or consequential damages, whether based in contract, warranty, indemnity or tort, negligence or strict liability. 12. Force Majeure. The performance of this Agreement, except for the payment of money for services already rendered, may be suspended by either Party (a) in the event that the delivery or transportation of Waste by such Party is prevented by a cause or causes beyond the reasonable control of such Party , or (b) in the event that the transportation, storage, treatment, processing or disposal of Waste by such Party is prevented by a cause or causes beyond the reasonable control of such Party. Such causes shall include, but not be limited to, acts of God, acts of war, riot, fire, explosion, accident, flood, or sabotage; lack of adequate fuel, power, raw materials, labor or transportation facilities; government laws, regulations, requirements, orders or actions; breakage or failure of machinery or apparatus; national defense requirements; injunctions or restraining orders; labor trouble, strike, lockout or injunction (provided that neither Party shall be required to settle a labor dispute against its own best judgment). The Party asserting a right to suspend performance under this Section shall, within a reasonable time after it has knowledge of the effective cause, notify the other Party in writing of the cause for suspension, the performance suspended and the anticipated duration of suspension, and shall use its reasonable best efforts to rectify the effective cause of the suspension. 13. Extension of Time; Waiver of Performance. The Parties may extend the time for or waive the performance of any of the obligations or warranties of the other, or waive compliance by the other with any of the covenants or conditions contained in this Agreement. Any such extension or waiver shall be in writing and shall be signed by the Party extending or waiving the performance or decision deadline. 14. Notice. Except for notice given pursuant to Section 8 hereof, any notice to a Party pursuant to this Agreement shall be given by certified or registered mail, or by private carrier providing evidence of receipt as part of its services, addressed as follows: 6

Quarterly Meeting. Representatives of Safety-Kleen and Clean Harbors shall meet at least once in each calendar quarter during the term of this Agreement to review the implementation of this Agreement, unless otherwise agreed to in writing. Alternatively, if agreed to by the Parties, such meeting may take place by telephone conference call. 17. Access to Records; Confidential Information. The Parties shall afford their respective representatives such access during normal business hours and upon reasonable notice to each other's business records as may be necessary to ascertain their compliance with the terms of this Agreement, including, in the case of environmental audits from time to time conducted by either Party, access to such records of the Facilities demonstrating compliance with applicable environmental laws or regulations. Except as required by law or as is necessary to perform this Agreement, any information obtained by either Party from the other shall not be disclosed or used by such Party for any purpose other than for which it was intended pursuant to this Agreement, and except as required by law, neither Party shall disclose to others the terms of this Agreement.

Agreement shall require either Party to disclose to the other Party or permit the other Party to examine proprietary or confidential information. 18. Mediation of Disputes. The Parties agree to mediate any dispute or claim between them arising out of this Agreement before resorting to arbitration or court action. Mediation is a process in which parties attempt to resolve a dispute by submitting it to an impartial, neutral mediator who is authorized to facilitate the resolution of the dispute but who is not empowered to impose a settlement on the parties. Mediation fees, if any, shall be divided equally among the Parties involved. Before the mediation begins, the Parties agree to sign a document limiting the admissibility in arbitration or any civil action of anything said, any admission made, and any documents prepared, in the course of the mediation, consistent with Evidence Code Section 1119. If any Party commences an arbitration or court action based on a dispute or claim to which this Section 18 applies without first attempting to resolve the matter through mediation, then in the discretion of the arbitrator(s) or judge, that Party shall not be entitled to recover attorneys' fees even if they would otherwise be available to that Party in any such arbitration or court action. 19. Assignment. This Agreement shall not be transferred or assigned except to a parent, successor, subsidiary or other affiliated company of either Party and except as collateral security to an institutional lender which shall have all of the rights of a secured Party under the Uniform Commercial Code; provided, however, that no such transfer or assignment shall operate to relieve either Party of its responsibilities under this Agreement. 20. Construction of Agreement. This instrument is to take effect as a sealed instrument and is to be construed according to the laws of the Commonwealth of Delaware. This instrument sets forth the entire agreement between the Parties with respect to the subject matter hereof and is binding upon and inures to the benefit of the Parties hereto and their respective subsidiaries, affiliates, legal successors and assigns. It may be canceled, modified or amended only by a written instrument executed by the Parties. In no event shall the preprinted terms or conditions found on any Safety-Kleen or Clean Harbors purchase or work order or similar document be considered an amendment, modification or supplement to this Agreement, even if such document is signed by representatives of both Parties; such preprinted terms and conditions shall be considered null and void and of no effect. The captions are used only as a matter of convenience, and are not to be considered a part of this Agreement or to be used in determining the intent of the Parties to it. 21. Execution in Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original and constitute one and the same agreement. 22. Confidentiality. The Parties shall protect the confidentiality of confidential business information obtained in connection with this Agreement ("Confidential Business Information"). Confidential Business Information shall include, without limitation, the terms of this Agreement, the terms and conditions of any pricing arrangements made pursuant tot his Agreement, the identity of either Party's customers, suppliers, or vendors.

programs, plants, processes, products, costs, customers, suppliers, vendors, equipment or operations that may come within the knowledge of the other Party in connection with the activities arising from the performance of this Agreement, and any other information relating to the business or affairs of either Party shall hereafter indicate in writing to the other Party to be "proprietary" or "confidential." Except for the identity of a Party's customers, Confidential Business Information shall not include information that is required to be disclosed under state or federal laws or regulations, or any information that (i) has been published and has become a part of the public domain by the acts or omissions of a Party (ii) was in the other Party's possession prior to disclosure or (ii) has been received from a third Party without restrictions on its disclosure. Neither Party shall disclose any Confidential Business Information to any person, other than its employees or agents who require such Confidential Business Information in connection with the performance of services pursuant to this Agreement. Both Parties shall use reasonable efforts to ensure that such employees and agents shall themselves protect the confidentiality of such Confidential Business Information. Upon termination of this Agreement, the Parties shall return to the other Party (and require its employees and agents to do likewise) all copies of documents containing Confidential Business Information (other than documents specifically required by law to be retained by the other Party) and may retain one copy of its own for archival purposes only provided, however, the confidentiality of the archival copy is maintained and shall survive termination of this Agreement. 9

As of their respective dates, the financial statements of the Company included in the SEC Documents complied as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto. Such financial statements have been prepared in accordance with generally accepted accounting principles, consistently applied, during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or may be condensed or summary statements) and fairly present in all material respects the consolidated financial position of the Company and its Subsidiaries as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments). None of the Company nor any of its Subsidiaries have any material liabilities or obligations of any nature (whether known or unknown, and whether absolute, accrued, contingent, matured, liquidated, unasserted or otherwise) of a kind required by generally accepted accounting principles ("GAAP") to be set forth on a financial statement that is not fully and adequately reflected or reserved against in the financial statements contained in the Company's most recent Annual Report on Form 10-K and Quarterly Report on Form 10-Q filed with the SEC, other than liabilities expressly assumed in connection with the CSD Acquisition and liabilities and obligations incurred since June 30, 2002 in the ordinary course of business consistent with past practice that are not material in amount.

To the best of the Company's knowledge, after due inquiry of the -8-
