NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) BASIS OF PRESENTATION

The consolidated interim financial statements included herein have been prepared by the Company, pursuant to the rules and regulations of the Securities and Exchange Commission and, in the opinion of management, include all adjustments which, except as described elsewhere herein, are of a normal recurring nature, necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented. The results for interim periods are not necessarily indicative of results for the entire year. The financial statements presented herein should be read in connection with the financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2002.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company’s management to make certain estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of the contingent assets and liabilities at the date of the financial statements. These estimates and assumptions will also affect the reported amounts of certain revenues and expenses during the reporting period. Actual results could differ materially based on any changes in the estimates and assumptions that the Company uses in the preparation of its financial statements. Additionally, the estimates and assumptions used in determining landfill airspace amortization rates per yard, capping, closure and post-closure liabilities as well as environmental remediation liabilities require significant engineering and accounting input. The Company reviews these estimates and assumptions no less than annually. In many circumstances, the ultimate outcome of these estimates and assumptions may not be known for decades into the future. Actual results could differ materially from these estimates and assumptions due to changes in environmental-related regulations or future operational plans, and the inherent imprecision associated with estimating matters so far into the future. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this report.

(2) ACQUISITION

Effective September 7, 2002, the Company purchased from Safety-Kleen Services, Inc. (the “Seller”) and certain of the Seller’s domestic subsidiaries substantially all of the assets of the Chemical Services Division (the “CSD”) of Safety-Kleen Corp. (“Safety-Kleen”). The sale included the operating assets of certain 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 sale order issued on June 18, 2002 (the “Sale Order”) 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 and its domestic subsidiaries (including the Seller) have been operating since June 2000 as debtors in possession. The Sale 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.

The assets of the CSD (including the assets of the CSD Canadian Subsidiaries) acquired by the Company consist primarily of 44 hazardous waste treatment and disposal facilities including, among others, 21 treatment, storage or disposal facilities (six of which have since been closed by the Company), six wastewater treatment facilities (one of which has since been closed by the Company), nine commercial landfills and four incineration facilities. Such facilities are located in 30 states, Puerto Rico, six Canadian provinces and Mexico. The most significant of such facilities include landfills in Buttonwillow, California with approximately 10.3 million cubic yards of remaining capacity, in Lambton, Ontario with approximately 6.0 million cubic yards of remaining capacity, which is the largest of the total of three hazardous waste landfills in Canada, and in Waynoka, Oklahoma with approximately 1.6 million cubic yards of remaining capacity; and incinerators in Deer Park, Texas which is the largest hazardous waste incinerator in the United States, and in Aragonite, Utah. Additional significant facilities are the incinerators in Mercier, Quebec and Lambton, Ontario. 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 primary reasons for the acquisition of the CSD assets were to broaden the Company’s disposal capabilities and geographic reach, particularly in the West Coast and Southwest regions of the United States, in Canada and in Mexico, and to significantly expand the Company’s network of hazardous waste disposal facilities. In addition, the Company believes that the acquisition of hazardous waste facilities in new geographic areas will allow the Company to expand its site and industrial services which in turn could increase the utilization and profitability of the facilities. Finally, the Company believed that the acquisition would result in significant cost savings by allowing the Company to treat hazardous waste internally. The Company previously paid third parties to dispose of hazardous waste because the Company lacked the facilities required to dispose of the waste internally.

(2) ACQUISITION—(Continued)

On July 14, 2003, the Fourth Amendment to Acquisition Agreement (the “Fourth Amendment”) was executed between the Company and the Seller. The Fourth Amendment was structured as a global settlement and resolved certain issues between the parties as to (i) the amount of working capital delivered by the Seller to the Company as required by the Acquisition Agreement and subsequent amendments thereto, (ii) the amounts due between the parties under the Transition Services Agreement, which defined services that the Company and the Seller would provide to each other, and (iii) the “shortfall” amount due to the Company under the Waste Disposal Agreement (as discussed below). The Fourth Amendment provided for the Seller’s payment to the Company of $7.8 million in cash (the “Global Settlement Payment”), which was received in the quarter ended September 30, 2003.

The Company purchased the assets of the CSD for $34.3 million in cash, and incurred direct costs related to the transaction of $9.8 million. This gross purchase price of $44.1 million was partially offset by the global settlement payment of $7.8 million. The total purchase price of the acquisition is $36.3 million. In addition, the Company assumed with the transaction certain environmental liabilities valued at September 30, 2003 in accordance with generally accepted accounting principles at $184.5 million.

The Company has allocated the total purchase price for the CSD assets based upon the estimated fair value of each asset acquired and each liability assumed. The following table shows the initial allocation of the purchase price and direct costs incurred among the assets acquired, liabilities assumed, and liabilities accrued relating to the CSD assets acquired as of September 7, 2002, based on information then available (in thousands):

Estimated transaction costs		9,487			9,887			9,747

Cost of CSD assets acquired	$	43,817		$	44,217		$	36,327

The Company preliminarily estimated, based upon the due diligence performed and the information that it then knew, that the Company had assumed environmental liabilities of approximately $266.0 million in the acquisition of the CSD from Safety-Kleen. The Company revised its preliminary estimate and reduced such liability to $184.5 million. The $81.5 million net decrease in the assumed environmental liabilities consists of decreases that total $103.5 million which consists of a $50.0 million decrease due to the Company’s discounting the environmental remedial liabilities in order to record the liabilities at fair value under purchase accounting, a $46.7 million decrease as a result of adopting Statement of Accounting Standards No. 143 “Accounting for Asset Retirement Obligations” (“SFAS No. 143”) in the first quarter 2003, and a net $6.8 million reduction due to changes in estimates based on the Company’s evaluation of the obligations and changes in plan to settle obligations. These decreases were partially offset by a $22.0 million increase in environmental liabilities due to the Company being able to estimate in the third quarter 2003 the cost of remedial and legal liabilities relating to the Ville Mercier Legal Proceedings and Marine Shale Processors, as further discussed in Note 6, “Legal Proceedings,” that the Company was not previously able to estimate.

The Company engaged an independent appraisal firm to assist in determining the fair values of the property, plant, equipment and intangible assets, which were acquired as part of the assets of CSD. $12.7 million of the puchase price was allocated to properties held for sale as discussed in Note 4. Intangible assets recorded at $77.6 million consist of $72.9 million of permits and $4.7 million of customer profile databases. The valuation for intangible assets was based on discounted cash flows from operations of the acquired facilities to which those permits and customer profile databases relate. As the fair value of the assets acquired from the CSD is higher than the purchase price paid, the Company reduced the recorded value of the fixed assets and intangible assets as of the acquisition date by $281.3 million in order to record the assets at cost as required by generally accepted accounting principles in the United States. The implementation of SFAS No. 143 resulted in the adjustment of the carrying value of certain environmental liabilities assumed in the CSD acquisition and a corresponding reduction in the values allocated to the assets acquired under purchase accounting since there was no goodwill recorded in this transaction. The Company also concluded that the intangible assets acquired have finite lives and will amortize these assets over their estimated useful lives.

(2) ACQUISITION—(Continued)

Future adjustments that result from preacquisition contingencies will be included in the determination of net income in the period in which the adjustment is determined.

In connection with the acquisition of the CSD assets, the Company recorded integration liabilities of $12.6 million which consisted primarily of increases in lease costs, severance, environmental closure and other exit costs to close duplicative facilities and functions. Groups of employees severed and to be severed consist primarily of duplicative selling, general and administrative personnel and personnel at offices which were closed. The following table summarizes the purchase accounting liabilities recorded in connection with the acquisition of the CSD assets (in thousands):

Material business combinations require that pro forma results of operations for the current period be presented as though the business combination had been completed at the beginning of the period and corresponding prior period pro forma results of operations be presented as though the combination took place at the beginning of that period. Safety-Kleen has publicly disclosed that it has material deficiencies in many of its financial systems, processes and related internal controls. The Seller agreed in the Acquisition Agreement to provide the Company audited balance sheets for the CSD as of the end of each of the CSD’s three fiscal years in the period ended August 31, 2001, and the Company filed these balance sheets as part of the Form 8-K filed by the Company with the SEC on September 25, 2002. However, due to Safety-Kleen’s material deficiencies, Safety-Kleen’s auditors have advised Safety-Kleen that they will not be able to provide auditors’ reports with respect to the CSD’s statements of operations and cash flows for such three fiscal years. Additionally, Safety-Kleen’s pre-existing deficiencies in financial systems, processes, and related internal controls led the Company to believe that the historical unaudited financial statements of the CSD may not be reliable or accurate. Accordingly, the Company is unable to provide pro forma results of operations reflecting the combined operations of the Company and the CSD for any periods prior to the Company’s acquisition of the CSD assets. The Company has received a “no-action letter” from the SEC staff with respect to the Company’s inability to file audited statements of operations and cash flows for the CSD or a pro forma statement of operations based thereon. However, until the Company is

(2) ACQUISITION—(Continued)

able to obtain and file audited statements of operations and cash flows of the CSD (on a separate basis for any relevant periods prior to the closing and on a combined basis with the Company for periods following the closing) for at least three years (or such lesser period as the SEC staff may permit in the future), the Company will not be able to file registration statements for public securities offerings by the Company (except for offerings involving employee benefit plans and secondary offerings by holders of warrants and other securities). This could prevent the Company from being able to access the public capital markets for a period of up to three years following the closing, but it would not prevent the Company from obtaining financing through other sources such as private equity or debt placements and bank loans.

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 provides that during the three-year term of the Agreement, the BSSD will continue to utilize the Company (which now owns the facilities of the CSD) to provide hazardous waste treatment and disposal services at competitive prices and, in particular, that during the first six months following the closing that the BSSD would provide the Company with at least $15 million of disposal business. Any shortfall from the $15 million guarantee was to result in a payment to the Company of 40% of such shortfall. However, the amount of any such “shortfall” payment due the Company under the Master Waste Disposal Agreement was included within the Global Settlement Payment paid by the Seller to the Company on July 28, 2003 pursuant to the Fourth Amendment to the Acquisition Agreement as described above. The Master Waste Disposal Agreement also provides that during the three-year term of the Agreement, the Company will continue to use, at competitive prices, the services of the BSSD which were used by the CSD prior to the effective date of the CSD acquisition (September 7, 2002). Accordingly, both the Company and the BSSD should be significant customers of each other for at least the three years following such date.

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 the employment of the other.

(3) SIGNIFICANT ACCOUNTING POLICIES

(a) Reclassifications

Certain reclassifications have been made in the prior years’ Consolidated Financial Statements to conform with the 2003 presentation.

(b) New Accounting Pronouncements

In July 2001, the FASB issued SFAS No. 143, “Accounting for Asset Retirement Obligations.” SFAS No. 143 requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. When a liability is initially recorded, the entity capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement. The standard is effective for fiscal years beginning after June 15, 2002. The Company adopted SFAS No. 143 in the first quarter of 2003. The effects of this adoption in the first quarter of 2003 are described below under Note 7, “Remedial Liabilities and Change in Accounting for Asset Retirement Obligations.”

In April 2002, the FASB issued SFAS No. 145, “Rescission of FASB Statement No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections.” SFAS No. 145 rescinds SFAS No. 4, “Reporting Gains and Losses from Extinguishment of Debt,” and an amendment of that SFAS No. 64, “Extinguishment of Debt made to satisfy Sinking-Fund Requirements.” This Statement also rescinds SFAS No. 44, “Accounting for Intangible Assets of Motor Carriers.” This SFAS amends SFAS No. 13, “Accounting for Leases,” to eliminate an inconsistency between the required accounting for sale-leaseback transactions and the required accounting for certain lease modifications that have economic effects that are similar to sale-leaseback transactions. This Statement also amends other existing authoritative pronouncements to make various technical corrections, clarify meaning, or describe their applicability under changed conditions. SFAS No. 145 is effective for fiscal years beginning after May 15, 2002. The adoption of SFAS No. 145 resulted in the reclassification of the extraordinary loss related to early extinguishment of debt of $24,658,000, recorded in the quarter ended September 30, 2002, to other expenses in arriving at its income or loss from operations for that period. The Company believes the adoption of SFAS No. 145 did not materially affect the Company’s financial condition.

(3) SIGNIFICANT ACCOUNTING POLICIES—(Continued)

In July 2002, the FASB issued SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities.” SFAS No. 146 requires companies to recognize costs associated with exit or disposal activities when they are incurred rather than at the date of a commitment to an exit or disposal plan. Examples of costs covered by the standard include lease termination costs and certain employee severance costs that are associated with a restructuring, discontinued operation, plant closing, or other exit or disposal activity. SFAS No. 146 is to be applied prospectively to exit or disposal activities initiated after December 31, 2002. Adoption of SFAS No. 146 as of January 1, 2003 did not have a material impact on the results of operations or financial condition for the three and nine months ended September 30, 2003.

In November 2002, the FASB issued FASB Interpretation No. 45, “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others” (“FIN 45”). It clarifies that a guarantor is required to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee, including its ongoing obligation to stand ready to perform over the term of the guarantee in the event that the specified triggering events or conditions occur. The objective of the initial measurement of the liability is the fair value of the guarantee at its inception. The initial recognition and initial measurement provisions of FIN 45 are effective for the Company on a prospective basis to guarantees issued after December 31, 2002. The Company will record the fair value of future material guarantees, if any. There were no guarantees issued in the three and nine months ended September 30, 2003.

In January 2003, the FASB issued FASB Interpretation No. 46 (“FIN 46”), “Consolidation of Variable Interest Entities.” FIN 46 requires that unconsolidated variable interest entities must be consolidated by their primary beneficiaries. A primary beneficiary is the party that absorbs a majority of the entity’s expected losses or residual benefits. In October 2003, the FASB issued FASB Staff Position (“FSP”) 46-6, “Effective Date of FASB Interpretation No. 46, Consolidation of Variable Interest Entities” (“VIE”) which delays the effective date of FIN 46 to December 15, 2003 for certain VIE’s. The adoption of FIN 46 had no impact on the Company’s results of operations or financial condition for the three and nine months ended September 30, 2003.

(c) Stock Options

The Company applies APB Opinion No. 25 and related interpretations in accounting for its stock-based employee compensation plans. Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation”, (“SFAS 123”), defines a fair value method of accounting for stock options and other equity instruments. Under the fair value method, compensation cost is measured at the grant date based on the fair value of the award and is recognized over the service period, which is usually the vesting period. The Company elected to continue to apply the accounting provisions of APB Opinion No. 25 for stock options.

Accordingly, no stock-based employee compensation cost is reflected in net income, as all options granted under those plans have an exercise price equal to the market value of the underlying common stock on the date of grant. Had compensation cost for the Company’s stock option grants been determined based on the fair value at the grant dates, as calculated in accordance with SFAS 123, the Company’s net income and net income per common share for the three and nine month periods ended September 30, 2003 and 2002, would approximate the pro forma amounts as compared to the amounts reported (dollars in thousands except for per share amounts):

(4) PROPERTIES HELD FOR SALE

As part of its plan to integrate the activities of the CSD into its operations, the Company determined that certain acquired properties were no longer needed for operations. The Company decided to sell these acquired properties; accordingly, the acquired surplus properties were transferred to properties held for sale. In the allocation of the purchase price of the CSD acquisition, the Company valued properties held for sale at the current appraised market value less estimated selling costs. Properties held for sale include only those properties that the Company believes can be sold within the next twelve months based on current market conditions and the asking price.

Long-term obligations	$	147,502	$	155,000

As described in the Form 10-K for the year ended December 31, 2002, the Company has outstanding a $100.0 million three-year revolving credit facility (the “Revolving Credit Facility”), $115.0 milllion of three-year non-amortizing term loans (the “Senior Loans”) and $40.0 million of five-year non-amortizing subordinated loans (the “Subordinated Loans”). 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 $100.0 million of letters of credit by providing cash collateral equal to 103% of the amount of such outstanding letters of credit.

The principal terms of the Revolving Credit Facility, the Senior Loans, the Subordinated Loans, and the L/C Facility are as follows:

Revolving Credit Facility. The Revolving Credit Facility allows the Company to borrow up to $100.0 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 Company’s Canadian Subsidiaries of $20.0 million in Canadian dollars and a line for the Company and its U.S. subsidiaries equal to $100.0 million in U.S. 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 $20.0 million. At September 30, 2003, letters of credit outstanding were $1.0 million and the Company had $35.8 million available to borrow. This consisted of borrowing availability in the U.S. of approximately $30.3 million and availability in Canada of approximately $5.5 million (USD). As amended by the amendments to the Loan and Security Agreement described below, 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 3.50%, with the balance at either the U.S. prime plus 0.50% for U.S. dollar loans or the Canadian prime rate plus 0.50% for Canadian dollar loans. The Revolving Credit Facility requires the Company to pay an unused line fee of 0.25% per annum on the unused portion of the revolving credit.

The Revolving Credit Facility provides for certain covenants the most restrictive of which required that the Company maintain minimum consolidated annualized earnings before interest, income taxes, depreciation and amortization (“EBITDA”), a non-GAAP measure defined below, of not less than $15.7 million for the fiscal quarter ended September 30, 2003. For the quarter ended September 30, 2003, EBITDA was (as described below) $16.0 million which was within covenant. The Company was also required to maintain an annualized rolling fixed charge coverage ratio of not less than 0.85 to 1.0 for the fiscal quarter ended September 30, 2003. At September 30, 2003, the fixed charge coverage ratio was 1.0 to 1.0 which was within covenant.

(5) FINANCING ARRANGEMENTS—(Continued)

For the first and second quarters of 2003, the Company violated the EBITDA loan covenant under the Revolving Credit Facility which was cured by amending the Loan and Security Agreement dated September 6, 2002 (the “Loan and Security Agreement”) with the Second Amendment to the Loan and Security Agreement (the “Second Amendment”) and the Third Amendment to the Loan and Security Agreement (the “Third Amendment”). Under the terms of the Third Amendment, the Company is now required to maintain consolidated EBITDA of not less than $32.3 million for the two quarters ending December 31, 2003. The required level of EBITDA then increases to $43.7 million for the three quarters ended March 31, 2004 to $59.5 million for the four quarters ended June 30, 2004. The required level of EBITDA then increases in approximately equal quarterly increments from $61.7 million to $68.6 million for the four consecutive quarters ending September 30, 2004 and June 30, 2005, respectively. The Company is now also required to maintain a fixed charge coverage ratio of not less than 0.90 to 1.0 for the two quarters ending December 31, 2003. The required fixed charge coverage ratio then increases to 0.95 to 1.0 for the three quarter period ending March 31, 2004, to 1.0 to 1.0 for the four quarter periods ending June 30, 2004 through December 31, 2004, to 1.1 to 1.0 for the four quarter period ending March 31, 2005, and to 1.2 to 1.0 for the four quarter period ending June 30, 2005.

In exchange for the lenders waving the violation of the EBITDA loan covenant for the first and second quarters of 2003 and resetting the loan covenants for future periods, the Second Amendment and Third Amendment required the Company to pay amendment fees that totaled approximately $0.4 million and the Third Amendment increased the interest rate from that of the Loan and Security Agreement from LIBOR plus 3.00% to LIBOR plus 3.50%, or from the U.S. prime rate to the prime rate plus 0.50% for U.S. based prime rate loans. For prime rate based borrowings in Canada, the Third Amendment increased the interest rate from that of the Loan and Security Agreement from the Canadian prime rate to the Canadian prime rate plus 0.50%. The increase in the interest rates under the Third Amendment became effective as of August 1, 2003 and will continue until such time as the Company has maintained a fixed charge coverage ratio in excess of 1.1 to 1.0 for three consecutive quarters. In such event, the interest rates will revert in future periods from LIBOR plus 3.50% to LIBOR plus 3.25%, from the U.S. prime rate plus 0.50% to the U.S. prime plus 0.25% for U.S. based prime rate loans, or from the Canadian prime plus 0.50% to Canadian prime plus 0.25% for Canadian based prime loans.

EBITDA under the Revolving Credit Facility for the quarter ended September 30, 2003 is calculated as follows, and EBITDA for the quarter ended September 30, 2003 may in the future be increased due to the inclusion of severance paid to former employees (dollars in thousands):

Net income	$	7,418
Accretion of environmental liabilities		2,745
Depreciation and amortization		6,787
Interest expense, net		6,048
Provision for income taxes		1,746
Change in value of embedded derivative		(8,748	)

EBITDA	$	15,996

Senior Loans and Subordinated Loans. The Senior Loans and the Subordinated Loans provide for certain covenants the most restrictive of which required that the Company maintain minimum consolidated annualized EBITDA of not less than $53.0 million for the four quarter period ended September 30, 2003. For the four quarter period ended September 30, 2003, EBITDA was (as described below) $54.3 million which was within covenant. The Company was also required to maintain an annualized fixed charge coverage ratio (as the term was redefined by the Third Amendment to the Financing Agreement as described below) of not less than 0.93 to 1.0 for the fiscal quarter ended September 30, 2003. For the fiscal quarter ended September 30, 2003, the fixed charge coverage ratio was 1.04 to 1.0 which was within covenant. The Company was also required to maintain a leverage ratio of consolidated funded indebtedness to consolidated annualized EBITDA of not more than 2.13 to 1.0 for the fiscal quarter ended September 30, 2003. For the fiscal quarter ended September 30, 2003, the leverage ratio was 1.81 to 1.0 which was within covenant.

For the first and second quarters of 2003, the Company violated certain of the loan covenants under the Senior Loans and Subordinated Loans which was cured by amending the Financing Agreement dated September 6, 2002 (the “Financing Agreement”) with the First Amendment to Financing Agreement (the “First Financing Amendment”) and the Second Amendment to Financing Agreement (the “Second Financing Amendment”). The Company is now required to maintain consolidated four quarters EBITDA of not less than $50.1 million for the quarter ended December 31, 2003. The required level of EBITDA then increases in approximately equal quarterly increments to $64.6 million, $80.3 million, $90.9 million, and $107.1 million for the years ending December 31, 2004, 2005, 2006 and 2007, respectively. The Company is also now required to maintain a fixed charge coverage ratio of not less than 0.80 to 1.0 for the four quarter period

CLEAN HARBORS, INC. AND SUBSIDIARIES

(5) FINANCING ARRANGEMENTS—(Continued)

ending December 31, 2003. The required fixed charge coverage ratio then increases in approximately equal quarterly increments to 1.12 to 1.0, 1.33 to 1.0, 1.43 to 1.0 and 1.55 to 1.0 for the four fiscal quarters ending December 31, 2004, 2005, 2006 and 2007, respectively. The Company is also now required to maintain a leverage ratio of not more than 2.27 to 1.0 for the four fiscal quarters ending December 30, 2003. The maximum leverage ratio allowed then decreases in approximately equal quarterly increments to 1.65 to 1.0, 0.98 to 1.0, 0.62 to 1.0 and 0.21 to 1.0 for the four fiscal quarters ending December 31, 2004, 2005, 2006 and 2007, respectively.

In exchange for the lenders waiving the violation of the loan covenants for the first and second quarters of 2003 and resetting the loan covenants for future periods, the First Financing Amendment and Second Financing Amendment required the Company to pay amendment fees totaling approximately $1.0 million. The Second Financing Amendment increased the interest rates from those of the Financing Agreement for Senior and Subordinated Loans from LIBOR plus 7.25% to LIBOR plus 7.75% and from 22.0% to 22.5%, respectively. The Amendments to the Financing Agreement also prohibit the Company from paying dividends in cash on its Series B Preferred Stock and Series C Redeemable Preferred Stock, and prohibit the repurchase or retirement of outstanding common stock, preferred stock, warrants and stock options.

In October 2003, the Financing Agreement was further modified by the Third Amendment to Financing Agreement (the “Third Financing Amendment”). The Third Financing Amendment redefined the fixed charge coverage ratio for the fiscal quarters ending September 30, 2003 through June 30, 2004 to exclude from capital expenditures the effect of correcting certain non-cash errors that had been made through application of purchase accounting in the preparation of the Consolidated Statements of Cash Flows for the six months ended June 30, 2003. Those corrections are described in Amendment No. 1 on Form 10-Q/A as filed on November 14, 2003 to the Company’s previously filed reports on Form 10-Q for the quarters ended March 31, 2003 and June 30, 2003.

EBITDA under the Financing Agreement, as amended, for the four fiscal quarters ended September 30, 2003 is calculated as follows (dollars in thousands):

Net loss	$	(1,642	)
Cumulative effect of change in accounting principle, net of tax		8

Net loss before change in accounting principle		(1,634	)
Accretion of environmental liabilities		9,460
Depreciation and amortization		25,638
Interest expense, net		22,739
Provision for income taxes		5,612
Restructuring charges		1,794
Change in value of embedded derivative		(9,323	)

EBITDA	$	54,286

L/C Facility. At September 30, 2003, letters of credit outstanding under the L/C Facility were $85.9 million.

EBITDA. In addition to disclosing financial results that are determined in accordance with generally accepted accounting principles, the Company also uses the non-GAAP measure EBITDA which the Company defines in accordance with the Financing Agreement, as amended, which is earnings before interest expense, income taxes, depreciation and amortization, accretion of environmental liabilities, gains or losses on the embedded derivative and restructuring expenses. The Company believes that EBITDA is useful to investors because it is an indicator of the strength and performance of the ongoing business operations, including the ability to fund capital expenditures and service debt. In addition to the inclusion of EBITDA in the loan covenants, the number of common shares to which the Company’s Series C Convertible Redeemable Preferred Stock can be converted into is dependent on the level of future EBITDA. The Company also uses EBITDA to measure the performance of operating units and awards management incentive bonuses based on the level of EBITDA attained.

EBITDA should not be considered an alternative to net income or loss or other measurements under accounting principles generally accepted in the United States of America as an indicator of operating performance or to cash flows from operating, investing, or financing activities as a measure of liquidity. EBITDA does not reflect working capital changes, cash expenditures for interest, taxes, capital improvements or principal payments on indebtedness. Furthermore, the Company’s measurement of EBITDA might be inconsistent with similar measures presented by other companies.

(6) LEGAL PROCEEDINGS

Item 3, “Legal Proceedings,” in the Company’s annual report on Form 10-K filed with the Securities and Exchange Commission on April 10, 2003 describes the material legal proceedings in which the Company was then involved. Those legal proceedings relate primarily to certain environmental liabilities to governmental agencies which the Company assumed as part of the purchase price for the Company’s acquisition effective September 7, 2002 of the assets of the Chemical Service Division (the “CSD”) of Safety-Kleen Services, Inc. and its subsidiaries (the “Sellers”). The only material changes which have subsequently occurred with respect to such legal proceedings are as follows.

Ville Mercier Legal Proceedings. As more fully described in the Company’s Form 10-K, the Company acquired as part of the CSD assets the stock of one of the Sellers’ former Canadian subsidiaries (the “Mercier Subsidiary”) which owns and operates a hazardous waste incinerator in Ville Mercier, Quebec (the “Mercier Facility”). A portion of the Mercier Facility is contaminated as a result of actions dating back to 1968, when the Quebec government issued to the unrelated company which then owned the Mercier Facility two permits to dump organic liquids into lagoons on the property. By 1972, groundwater contamination had been identified, and the Quebec government provided an alternate water supply to the municipality of Ville Mercier.

Ville Mercier and three neighboring municipalities filed in 1999 separate legal proceedings against the Mercier Subsidiary, certain related companies and certain former officers and directors, as well as against the Government of Quebec. The lawsuits assert that the defendants are jointly and severally responsible for the contamination of groundwater in the region, which the plaintiffs claim was caused by leakage from the former Ville Mercier lagoons and 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.

Because the continuation of such proceedings by the Mercier Subsidiary, which is now owned by the Company, will require the Company to incur legal and other costs and the risks inherent in any such litigation, the Company, as part of its integration plan for the CSD assets, determined to pursue settlement discussions with the governmental entities in Canada which are parties to such proceedings. As of December 31, 2002, the Company could not predict whether such proposed discussions would result in a settlement of the proceedings and, if so, the amount of the Company’s potential liability under such a settlement. Statement of Financial Accounting Standards No. 5 (“SFAS No. 5”), “Accounting for Contingencies,” requires that an estimated loss from a loss contingency be accrued and recorded as a liability if it is both probable and estimable, but SFAS No. 5 does not permit a company acquiring assets to record as part of the purchase price any assumed liabilities which are not both probable and estimable. As of December 31, 2002, the Company determined that the amount of potential liabilities relating to Ville Mercier were not both probable and estimable; accordingly, the Company did not then record any such liabilities as part of the purchase

price for the CSD assets. However, based upon discussions subsequently held with representatives of certain of those governmental entities, the Company now anticipates that as part of any such settlement it will likely agree to assume at least partial responsibility for remediation of certain environmental contamination and the Company has been able to estimate the likely cost of such remediation. Accordingly, the Company recorded in the third quarter of 2003, as adjustments to the purchase price of the CSD assets in accordance with generally accepted accounting principles, a net increase in recorded liabilities of $4.2 million (in U.S. dollars) primarily for remedial liabilities and associated legal costs relating to the Ville Mercier Legal Proceedings.

Marine Shale Processors. As further described in the Company’s Form 10-K, the Company’s agreement to pay, as part of the purchase price for the CSD assets, the Sellers’ share of certain cleanup costs payable to governmental entities under federal and state Superfund laws include certain potential liabilities which the Sellers expect to incur in the future in connection with an incinerator formerly owned and operated by Marine Shale Processors, Inc. Federal and state Superfund laws generally impose joint and several liability for the costs of cleaning up Superfund sites not only upon the owners and operators of such sites, but also upon persons or entities which in the past have either generated or shipped hazardous wastes to such sites for treatment, storage and/or disposal. Accordingly, the Superfund laws encourage potentially responsible parties (“PRPs”) to agree to share in specified or allocated percentages of the aggregate cleanup costs for Superfund sites by entering into consent decrees, settlement agreements or similar arrangements. Non-settling PRPs may be liable for any shortfalls in government cost recovery and may be liable to other PRPs for equitable contribution. Under the Superfund laws, a settling PRP’s financial liability could increase if the other settling PRPs were to become insolvent or if additional or more severe contamination were discovered at the relevant site(s).

Beginning in the mid-1980’s and continuing until July 1996, Marine Shale Processors, Inc., located in Amelia, Louisiana (“Marine Shale”), owned and operated a kiln that 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 regulation under the Resource Conservation Recovery Act (“RCRA”) and permitting requirements as a hazardous waste incinerator under applicable federal and state environmental laws. 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 was a hazardous waste, and that Marine Shale’s continued operation without required permits was illegal. Litigation between the EPA and Marine Shale began in 1990 and continued until July 1996, when the U.S. Fifth Circuit Court of Appeals ordered Marine Shale to shut down its operations. During the course of its operations, 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 was stockpiled on the premises of the Marine Shale facility. Almost all of this aggregate has since been moved to a nearby property owned by an affiliate of Marine Shale, known as Recycling Park, Inc. In accordance with a court order authorizing the movement of this material to this off-site location, all of the materials located at Recycling Park, Inc. comply with the land disposal restrictions of RCRA. Approximately 7,000 tons of aggregate remain at the Marine Shale facility. Moreover, as a result of past operations, soil and groundwater contamination may exist on the Marine Shale facility and the Recycling Park, Inc. site.

Although the Sellers never held an equity interest in Marine Shale, the Sellers were among the largest customers of Marine Shale in terms of tons of waste incinerated. At December 31, 2002, the Company determined that it lacked the data required to estimate its liability at the Marine Shale facility and the Recycling Park, Inc. site. During 2003, the Company obtained more complete information as to the potential status of the Marine Shale facility and the Recycling Park, Inc. site as a Superfund site or sites, the potential costs associated with possible removal and disposal of some or all of the aggregate and closure and remediation of the Marine Shale facility and the Recycling Park, Inc. site, and the respective shares of other identified potential PRPs on a volumetric basis. Accordingly, the Company has determined that the remedial liabilities and associated legal costs are now estimable, and the Company recorded in the third quarter of 2003 adjustments to the purchase price of the CSD assets in accordance with generally accepted accounting principles and offsetting liabilities of $13.4 million for the Company’s estimate of the Sellers’ proportionate share of environmental cleanup costs potentially payable to governmental entities under federal and/or state Superfund laws at the Marine Shale facility and Recycling Park, Inc site.

(7) REMEDIAL LIABILITIES AND CHANGES IN ACCOUNTING FOR ASSET RETIREMENT OBLIGATIONS

Effective January 1, 2003, the Company adopted SFAS No. 143, “Accounting for Asset Retirement Obligations” (“SFAS No. 143”). SFAS No. 143 requires companies to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. When a liability is initially recorded, the entity capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period using the credit-adjusted risk-free interest rate, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement. SFAS No. 143 requires upon initial application that companies reflect in their balance sheet (1) liabilities for any existing asset retirement obligations adjusted for cumulative accretion to the date of adoption of the Statement, (2) an asset retirement cost capitalized as an increase to the carrying amount of the associated long-lived asset, and (3) accumulated depreciation on that capitalized cost adjusted for accumulated depreciation to the date of adoption of the Statement. The cumulative effect of initially applying SFAS No. 143 was recorded as a change in accounting principle which requires that a cumulative-effect adjustment be recorded in the statement of operations.

The principal changes from the implementation of SFAS No. 143 were (1) a reduction in accrued landfill closure and post-closure obligations due to discounting the accruals at the Company’s credit-adjusted risk free interest rate of 14.0% as required under SFAS No. 143, instead of discounting the accruals at the risk-free interest rate of 4.9% used under purchase accounting at December 31, 2002, (2) a reduction in accrued financial assurance for closure and post-closure care of the facilities which will now be expensed in the period incurred under SFAS No. 143 and (3) a reduction due to discounting at the credit-adjusted risk-free rate previously undiscounted accrued cell closure costs. These reductions were partly offset by new closure and post-closure obligations recorded for operating non-landfill facilities determined under various probability scenarios as to when operating permits might be surrendered in the future and using the credit-adjusted risk-free rate. The reduction in the value of liabilities assumed in the CSD acquisition from the implementation of SFAS No. 143 of $46.7 million resulted in a corresponding reduction in the value allocated to the assets acquired (see Note 2 “Acquisition”). The implementation also resulted in a net of tax cumulative-effect adjustment of $8.0 thousand recorded in the statement of operations for the nine months ended September 30, 2003.

The implementation of SFAS No. 143 for companies in the hazardous waste industry is complex. Directly following is a table that summarizes the difference between the Company’s historical practices and current practices of accounting for facility closure, facility post-closure care, landfill cell closure and remedial liabilities. Following the table is a detailed discussion of the accounting for environmental liabilities and tables that detail the roll-forward of the environmental liabilities from December 31, 2002 through September 30, 2003.

Landfill Accounting

Landfill Accounting—The Company utilizes the life cycle method of accounting for landfill costs and the units-of-consumption method to amortize landfill construction costs over the estimated useful life of a landfill. Under this method, the Company includes future estimated construction costs, as well as costs incurred to date, in the amortization base. In addition, the Company includes probable expansion airspace (yet to be permitted airspace) in the calculation of the total remaining useful life of the landfill.

Landfill assets—Landfill assets include the costs of landfill site acquisition, permitting, preparation and improvement. These amounts are recorded at cost, which includes capitalized interest, as applicable. Landfill assets, 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 landfill assets is recorded on a units-of-consumption basis, such that the landfill assets should be completely amortized at the date the landfill ceases accepting waste. Changes in estimated costs to complete construction are applied prospectively to the amortization rate.

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 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 over the airspace within the entire trench, such that the cell construction costs will be fully amortized.

The design and construction of a landfill does not create a landfill asset retirement obligation. Rather, the asset retirement obligation for cell closure, the cost associated with capping each cell is incurred in relatively small increments as waste is placed in the landfill. Therefore, the cost required to construct the cell cap is capitalized as an asset retirement cost and a liability of an equal amount is established, based on the discounted cash flow associated with each capping event, as airspace is consumed. Spending for cell capping is reflected as a change in liabilities within operating activities in the statement of cash flows.

Final closure and post-closure liabilities—The Company has material financial commitments for the costs associated with requirements of the United States Environmental Protection Agency (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 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 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 and leachate management. Regulatory post-closure periods are generally 30 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.

For landfills purchased, the Company assessed and recorded 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.

Landfill capacity—Landfill capacity, which is the basis for the amortization of landfill assets 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.

•

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 approval from the Company’s Chief Financial Officer and review by the Audit Committee of the Board of Directors. As of September 30, 2003 there was one unpermitted expansion included in the Company’s landfill accounting model, which represents approximately 29% of the Company’s remaining airspace at this date. This expansion does not represent an exception to the Company’s established criteria.

As of September 30, 2003, the Company has 11 active landfill sites (including the Company’s two non-commercial landfills), which have estimated remaining lives (based on anticipated waste volumes and remaining highly probable airspace) as follows:

Facility Name	Location	Remaining lives (Years)	Remaining Highly Probable Airspace (cubic yards) (in thousands)
Facility Name	Location	Remaining lives (Years)	Permitted	Unpermitted	Total
Altair	Texas	0.1	9		9

			18,647	5,493	24,140

In addition, the Company had 2.9 million cubic yards of permitted but not highly probable, airspace as of September 30, 2003. Permitted, but not highly probable, airspace is permitted airspace whose use the Company has determined is uncertain.

Non-Landfill Closure and Post-Closure

Final closure and post-closure obligations for facilities other than landfills. Final closure costs include costs required to dismantle and decontaminate certain structures 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. Final closure and post-closure costs are increased for inflation (2.0% for the periods ended September 30, 2003) and discounted at the Company’s credit-adjusted risk-free interest rate (14.0% for the period ended September 30, 2003). Under SFAS No. 143, the cost of financial assurance for the closure and post-closure care periods cannot be accrued but rather is a period cost. Under SFAS No. 143, the cost of financial assurance is considered in the determination of the credit-adjusted risk-free interest rate used to discount the closure and post-closure obligations.

Remedial Liabilities

Remedial liabilities, including Superfund 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. SFAS No. 143 applies to asset retirement obligations that arise from normal operations. Almost all of the Company’s remedial liabilities were assumed as part of the acquisition of the CSD from Safety-Kleen Corp., and the Company believes that most of the remedial obligations did not arise from normal operations. Remedial liabilities assumed relating to the acquisition of the CSD from Safety-Kleen are and will continue to be inflated using the inflation rate at the time of acquisition (2.4%) until the expected time of payment then discounted at the risk free interest rate at the time of acquisition (4.9%). Remedial liabilities incurred subsequent to the acquisition and remedial liabilities of the Company that existed prior to the acquisition have been and will continue to be recorded at the estimated current value of the liability which is neither increased for inflation nor reduced for discounting. Certain costs previously classified as remedial costs were reclassified as closure costs at September 30, 2003, if the Company determined that the remedial liability arose from normal operations.

Claims for Recovery

The Company records claims for recovery from third parties relating to environmental liabilities only when realization of the claim is probable. The gross environmental liability is recorded separately from the claim for recovery on the balance sheet.

Discounting Landfill Closure, Post-Closure and Remedial Liabilities

Generally, remedial liabilities are not discounted. However, under purchase accounting, acquired liabilities are recorded at fair value, which requires taking into consideration inflation and discount factors. Accordingly, as of the acquisition date, the Company recorded the environmental liabilities assumed as part of the acquisition of the CSD at their fair value, which was calculated by inflating costs in current dollars using an estimate of future inflation rates as of the acquisition date until the expected time of payment then discounted to its present value using a risk free discount rate as of the acquisition date.

Subsequent to the acquisition, discounts were and will be applied to the environmental liabilities as follows:

•

Final closure and post-closure liabilities at December 31, 2002 were inflated using estimates of future inflation rates (2.4% at December 31, 2002) until the time of payment, then discounted using a risk-free interest rate (4.9% at December 31, 2002). The Company adopted Statement of Financial Accounting Standards No. 143, “Accounting for Asset Retirement Obligations” (“SFAS No. 143”) in the first quarter of 2003. Under SFAS No. 143 final closure and post-closure liabilities are inflated using estimates of future inflation until the time of payment then discounted using the Company’s credit adjusted risk free interest rate.

•

Remedial liabilities assumed relating to the acquisition of the CSD from Safety-Kleen are and will continue to be inflated using the inflation rate at the time of acquisition (2.4%) until the expected time of payment then discounted at the risk free interest rate at the time of acquisition (4.9%).

•

Remedial liabilities incurred subsequent to the acquisition and remedial liabilities of the Company that existed prior to the acquisition have been and will continue to be recorded at the estimated current value of the liability which is neither increased for inflation nor reduced for discounting.

Estimation of Certain Preacquisition Contingencies— Statement of Financial Accounting Standards No. 5, “Accounting for Contingencies,” requires that an estimated loss from a loss contingency be accrued and recorded as a liability if it is both probable and estimable, but the Statement does not permit a company acquiring assets to record as part of the purchase price for those assumed liabilities which are not both probable and estimable. As described in Note 8, “Legal Proceedings,” to the Company’s audited financial statements as of December 31, 2002, and as included in the Form 10-K filed with the Securities and Exchange Commission on April 10, 2003 and as updated in Note 6, “Legal Proceedings,” of this Form 10-Q under the headings “Ville Mercier Legal Proceedings” and “Marine Shale Processors,” the Company was previously unable to estimate the amount of potential remedial liabilities in connection with the facility and site which are the subject of these proceedings, but, as part of the integration plan of the CSD acquisition, the Company committed to obtaining the data required so that the Company could record such liabilities as adjustments to the purchase price. Sufficient additional information on these proceedings was obtained to allow the Company to record these liabilities as adjustments to the purchase price for the CSD assets in accordance with generally accepted accounting principles. Accordingly, additional discounted environmental liabilities have been recorded as part of the purchase price in the quarter ended September 30, 2003 in the amounts of $13.4 million and $4.2 million relating to Marine Shale Processors and the Ville Mercier Legal Proceedings, respectively.

REMEDIAL LIABILITIES AND CHANGES IN ACCOUNTING FOR ASSET RETIREMENT OBLIGATIONS—(Continued)

Remedial liabilities, including Superfund liabilities—As described in the tables above, the Company had as of September 30, 2003 a total of $156.6 million of estimated liabilities for remediation of environmental contamination, of which $5.5 million related to the Company’s landfills and $151.1 million related to non-landfill facilities (including Superfund sites owned by third parties). The Company periodically evaluates potential remedial liabilities at sites that it owns or operates or to which the Company or the Sellers of the CSD assets (or the respective predecessors of the Company or the Sellers) transported or disposed of waste, including 52 active or Superfund sites as of September 30, 2003. As described in Note 8, “Legal Proceedings,” of the Company’s audited financial statements for the year ended December 31, 2002 included in the Form 10-K filed with the Securities and Exchange Commission on April 10, 2003, the Company has assumed and agreed to pay as part of the purchase price for the CSD assets the Sellers’ share of cleanup costs payable to governmental entities for certain other sites where one or more of the Sellers have been named or may potentially be named as a PRP. 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 based upon management’s judgment and prior experience, for the Company’s best estimate of the liability.

Remediation liabilities are inherently difficult to estimate. Estimating remedial liabilities requires that the existing environmental contamination be understood. There is a risk that the actual quantities of contaminates differ from the results of the site investigation, and there is a risk that contaminates exist that have not been identified by the site investigation. In addition, the amount of remedial liabilities recorded are dependent on the remedial method selected. There is a risk that funds will be expended on a remedial solution that is not successful which could result in the additional incremental costs of an alternative solution. Such estimates, which are subject to change, are subsequently revised if and when additional information becomes available.

In connection with the Company’s acquisition of the CSD assets, the Company performed extensive due diligence, including hiring third party engineers and attorneys to estimate the aggregate liability for environmental liabilities to which the Company became subject as a result of the acquisition. Those environmental liabilities relate to the active and discontinued hazardous waste treatment and disposal facilities which the Company acquired as part of the CSD assets and 20 Superfund sites owned by third parties for which the Company agreed to indemnify certain environmental liabilities owed or potentially owed by the Sellers. In the case of each such facility and site, the Company’s estimate of remediation liabilities involved an analysis of such factors as (i) the nature and extent of environmental contamination (if any), (ii) the terms of applicable permits and agreements with regulatory authorities as to clean-up procedures and whether modifications to such permits and agreements will likely need to be negotiated, (iii) the cost of performing anticipated clean-up activities based upon current technology, and (iv) in the case of Superfund and other sites where other parties will also be responsible for a portion of the clean-up cost, the likely allocation of such costs and the ability of such other parties to pay their share. Based upon the Company’s analysis of each of the above factors in light of currently available facts, existing technology, and presently enacted laws and regulations, the Company estimates that its aggregate liabilities as of September 30, 2003 (as calculated in accordance with generally accepted accounting principles) for future remediation for all facilities and closure and post-closure liabilities for non-landfill facilities relating to all of its owned or leased facilities and the Superfund sites for which the Company has current or potential liability is approximately $156.6 million. The Company also estimates that it is “reasonably possible”, as that term is defined in SFAS No. 5 (“more than remote but less than likely”), that the amount of such total liabilities could be up to $22.6 million greater than such $156.6 million, and the Company believes that it is also possible that the amount of such total liabilities could be less than such $156.6 million. Future changes in either available technology or applicable laws or regulations could affect such estimates of environmental liabilities. Since the Company’s satisfaction of the liabilities will occur over many years and in some cases over periods of 30 years or more, the Company cannot now reasonably predict the nature or extent of future changes in either available technology or applicable laws or regulations and the impact that those changes, if any, might have on the current estimates of environmental liabilities.

	Totals	$	156,640	100	%	$	22,568

Revisions to remedial reserve requirements may result in upward or downward adjustments to income from operations in any given period. 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.

INCOME TAXES

SFAS 109, “Accounting for Income Taxes,” requires that a valuation allowance be established when, based on an evaluation of verifiable evidence, there is a likelihood that some portion or all of the deferred tax assets will not be realized. The Company continually reviews the adequacy of the valuation allowance for deferred taxes. For the three and nine months ended September 30, 2003, a full valuation allowance was maintained against the Company’s net U.S. deferred tax asset position and no U.S. tax benefit was recorded.

In the third quarter of 2002, the Company established a $16.9 million valuation allowance on the net U.S. deferred tax assets recorded in connection with the acquisition of the CSD assets. In the same quarter, the Company established a valuation allowance against its existing net deferred tax assets position of $1.1 million in recognition of the difficulty posed in projecting future taxable net income in view of the acquisition. All reductions to the valuation allowance associated with the CSD acquisition in the future will be recorded as a decrease to acquisition related intangible assets, rather than a tax provision benefit.

(10) RESTRUCTURING

For the year ended December 31, 2002, the Company recorded a restructuring charge of $750,000 related to the acquisition of the assets of the CSD. The restructuring charge consisted of $250,000 for severance for individuals that were employees of the Company prior to the acquisition, and $500,000 of costs associated with the decision to close parts of facilities and sales offices that were operated by the Company prior to the acquisition and that became duplicative due to facilities and sales offices acquired as part of the CSD assets. The Company is in the process of completing the restructuring. The following table summarizes the activity from the acquisition date through September 30, 2003 (in thousands):

(11) SEGMENT REPORTING

Segment information has been prepared in accordance with SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information.” Performance of the segments is evaluated on several factors, of which the primary financial measure is operating income before interest, taxes, depreciation, amortization and restructuring and other acquisition costs (“EBITDA Contribution”). Transactions between the segments are accounted for at the Company’s estimate of fair value based on similar transactions with outside customers. In general, SFAS No. 131 requires that business entities report selected information about operating segments in a manner consistent with that used for internal management reporting.

The Company has two reportable segments: Technical Services and Site Services.

Technical Services include:

•

treatment and disposal of industrial wastes, which includes physical treatment, resource recovery and fuels blending, incineration, landfills, wastewater treatment, lab chemical disposal and explosives management;

•

collection, transportation and logistics management;

•

categorization, specialized repackaging, treatment and disposal of laboratory chemicals and household hazardous wastes, which are referred to as CleanPack^{^®} services; and

•

Apollo Onsite Services, which provides customized environmental programs at customer sites.

These services are provided through a network of service centers where a fleet of trucks, rail or other transport is dispatched to pick up customers’ waste either on a pre-determined schedule or on demand, and then to deliver waste to a permitted facility. From the service centers, chemists can also be dispatched to a customer location for the collection of chemical waste for disposal.

Site Services provide highly skilled experts utilizing specialty equipment and resources to perform services, such as industrial maintenance, surface remediation, groundwater restoration, site and facility decontamination, emergency response, site remediation, PCB disposal, oil disposal, analytical testing services, information management services and personnel training. The Company offers outsourcing services for customer environmental management programs as well, and provides analytical testing services, information management and personnel training services.

The Company markets these services through its sales organizations and, in many instances services in one area of the business support or lead to work in other service lines. Expenses associated with the sales organizations are allocated based on external revenues by segment.

Overview

The Company provides a wide range of environmental services and solutions to a diversified customer base in the United States, Puerto Rico, Mexico and Canada. The Company seeks to be recognized by customers as the premier supplier of a broad range of value-added environmental services based upon quality, responsiveness, customer service, information technologies, breadth of product offerings and cost effectiveness.

Effective September 7, 2002, the Company purchased from Safety-Kleen Services, Inc. (the “Seller”) and certain of the Seller’s domestic subsidiaries substantially all of the assets of the Chemical Services Division (the “CSD”) of Safety-Kleen Corp. (“Safety-Kleen”). That acquisition broadened the Company’s disposal capabilities, geographic reach and significantly expanded the Company’s network of hazardous waste disposal facilities. Following the acquisition, the Company became one of the largest providers of environmental services and the largest operator of hazardous waste treatment and disposal facilities in North America. The Company believes that the acquisition of hazardous waste facilities in new geographic areas will allow the Company to expand its service area and has resulted in significant cost savings by allowing the Company to treat and dispose of hazardous waste internally that the Company previously paid third parties to dispose of and that further savings can be realized by eliminating redundant selling, general and administrative expenses and inefficient transportation costs.

The Company believed that significant synergies existed between the Company and the former CSD operations. The Company planned to reduce expenses by use of common information management systems to minimize disposal costs outside the integrated network of facilities by sending waste to the disposal facilities that it now owns. The Company planned to eliminate duplicate costs relating to overlapping operations on a geographic basis. The integration of operations and reduction of the combined entities operating costs are ongoing.

In addition, as part of the acquisition, the Company assumed certain environmental liabilities valued as of September 30, 2003 in accordance with accounting principles generally accepted in the United States of America (“GAAP”) of approximately $184.5 million. The Company now anticipates such liabilities will be payable over many years and that cash flows generated from operations will be sufficient to fund the payment of such liabilities when required. However, events not now anticipated (such as future changes in environmental laws and regulations) could require that such payments be made earlier or later or in greater or lesser amounts than now anticipated.

As further discussed in Item 4, “Controls and Procedures,” Safety-Kleen publicly disclosed that it historically had material deficiencies in many of its financial systems, processes and related internal controls. Due to the deficiencies in these systems and the Company’s belief that it would be able to utilize its own systems in order to improve the operations of the former CSD, the decision was made to integrate the U.S. operations of the former CSD into the Company’s business and financial reporting systems effective as of the acquisition date. During the initial period of integration, the Company experienced deficiencies in certain of its internal controls. The Company has made significant progress in resolving but has not yet resolved all of the internal control weaknesses caused by the integration of the CSD into the Company’s systems.

ENVIRONMENTAL LIABILITIES

Description	Historical Practice	Current Practice (Effective January 1, 2003)
*Definitions:*
Cell closure	Cell closure costs are the costs required to construct a landfill cell cap.	No change.

Landfill closure	Includes costs required to dismantle certain landfill structures and regulatory costs such as groundwater monitoring, leachate management and financial assurance.	No change, except that financial assurance is no longer included as a cost component of landfill closure but rather is expensed as incurred. The cost of financial assurance is considered in the determination of the credit-adjusted risk-free interest rate.

Landfill post-closure	Costs include routine monitoring and maintenance of a landfill after it has closed, ceased to accept waste and been certified as closed by the applicable state regulatory agency. Costs included financial assurance.	No change, except that financial assurance is no longer included as a cost component of landfill post-closure but rather is expensed as incurred. The cost of financial assurance is considered in the determination of the credit-adjusted risk-free interest rate.

Non-landfill closure	Costs of decontaminating waste handling equipment, pipes, enclosures, etc. contaminated in the normal course of operations. Costs included financial assurance.	No change, except that financial assurance is no longer included as a cost component of non-landfill closure but rather is expensed as incurred. The cost of financial assurance is considered in the determination of the credit-adjusted risk-free interest rate.

Non-landfill post-closure	Costs include routine monitoring and maintenance after the facility has closed, ceased to accept waste and been certified as closed by the applicable state regulatory agency. Costs included financial assurance. Post-closure care is not typically required for permitted non-landfill facilities.	No change, except that financial assurance is no longer included as a cost component of non-landfill post-closure but rather is expensed as incurred. The cost of financial assurance is considered in the determination of the credit-adjusted risk-free interest rate.

Remedial liabilities	The costs of removal or containment of contaminated material including material that became contaminated as part of normal operations.	The costs of removal or containment of contaminated material that did not arise as the result of normal operations. Certain costs previously classified as remedial costs were reclassified as closure costs based on SFAS No. 143 requiring that closure costs arising out of normal operations be accounted for as part of the asset retirement obligation.

*Discount Rate:*	Risk-free rate (4.9% at December 31, 2002) was used to discount accrued closure and post-closure obligations, and remedial obligations assumed as part of the acquisition of the CSD assets from Safety-Kleen Corp. Remedial obligations incurred in the course of operations are generally undiscounted.	Credit-adjusted, risk-free rate (14.0% at January 1, 2003) for liabilities accrued under SFAS No. 143. Remedial obligations assumed as part of the acquisition of the CSD assets from Safety-Kleen Corp. are and will continue to be discounted at the risk free interest rate at the time of the acquisition (4.9%). No change to remedial obligations incurred in the course of operations.

Description	Historical Practice	Current Practice (Effective January 1, 2003)

*Cost Estimates:*	Costs were estimated based on performance, principally by third parties, with a reasonable portion estimated at the Company’s internal cost.	No change, except that the cost of any activities performed internally must be increased to represent an estimate of the amount a third party would charge to perform such activity.

*Inflation:*	Cost was inflated to period of performance (2.4% for the period ended December 31, 2002).	Inflation rate changed to 2.0% effective January 1, 2003.

*Recognition of Assets and Liabilities:*

Cell closure	Cell closure was accrued on the units-of-consumption basis, such that the total amount required to cap the cell is accrued when that specific cell ceases accepting waste.	Each capping event is accounted for as a discrete obligation. All capping is recorded as a liability and asset, based on the discounted cash flow associated with each capping event, as airspace is consumed related to the specific capping event; spending is reflected as a change in liabilities within operating activities in the statement of cash flows.

Landfill closure and post-closure	Accrued over the life of the landfill; the discounted cash flow associated with such liabilities was recorded to accrued environmental liabilities, with a corresponding charge to cost of operations as airspace is consumed.	Accrued over the life of the landfill; the discounted cash flow associated with such liabilities is recorded to accrued environmental liabilities, with a corresponding increase in landfill assets as airspace is consumed.

Non-landfill closure and post-closure	Closure and post-closure costs were accrued when a decision was made to close a non-landfill facility.	At the time of facility acquisition or construction, the present value of the asset retirement obligation is recorded as an asset and a retirement liability is recorded in the same amount. The asset retirement cost is depreciated over the estimated life of the facility and the liability is accreted at the credit-adjusted risk free interest rate.
*Statement of Operations Expense:*

Liability accrual	Expense charged to cost of operations at same amount accrued to liability.	Not applicable.

Amortization of asset retirement cost	Not applicable for cell closure, landfill and non-landfill facility closure and post-closure.	Landfill facilities are amortized to depreciation and amortization expense as airspace is consumed over the life of cell or landfill. Non-landfill facilities are amortized to depreciation and amortization expense using the straight-line method over the estimated life of the facility.

Accretion	Expense, charged to cost of operations, was accrued at risk-free rate over the life of the landfill as airspace was consumed. Remedial liabilities were accreted at the risk-free interest rate using the effective interest method.	Expense, charged to cost of operations, is accreted at credit-adjusted, risk-free rate (14.0%) under the effective interest method.

Landfill Accounting

•

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.

•

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.

•

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.

Results of Operations

The Company’s operations are managed as two segments: Technical Services and Site Services. Technical Services include treatment and disposal of industrial wastes via incineration, landfill or wastewater treatment, collection and transporting of containerized and bulk waste, categorization, specialized repackaging, treatment and disposal of laboratory chemicals and household hazardous wastes, which are referred to as CleanPack^® services, and the Apollo Onsite Service, which customizes environmental programs at customer sites. This is accomplished through a network of service centers where a fleet of trucks, rail or other transport is dispatched to pick up customers’ waste either on a pre-determined schedule or on demand, and then to deliver waste to a permitted facility. From the service centers, chemists can also be dispatched to a customer location for the collection of chemical waste for disposal. Site Services provide highly skilled experts utilizing specialty equipment and resources to perform services, such as site decontamination, remediation projects, selective demolition, emergency response, spill cleanup and vacuum services at the customer’s site or another location. These services are dispatched on a scheduled or emergency basis. The Company also offers outsourcing services for customer environmental management programs, and provides analytical testing services, information management and personnel training services.

The following table sets forth for the periods indicated certain operating data associated with the Company’s results of operations. This table and subsequent discussions should be read in conjunction with Item 6, “Selected Financial Data,” and Item 8, “Financial Statements and Supplementary Data” of the Annual Report on Form 10-K and Item 1, “Financial Statements” in this report.

Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”)

The Company defines “EBITDA” as it is defined in the Financing Agreement as amended between the Company and Ableco Finance LLC, which is net income or loss, excluding interest, taxes, depreciation and amortization, accretion of environmental liabilities, restructuring charges, effects of discontinued operations, other non-recurring costs, and certain extraordinary or non-recurring gains or losses. The Company’s management considers EBITDA to be a measurement of performance which provides useful information to both management and investors. The Company’s Revolving Credit Facility, Senior Loans and Subordinated Loans outstanding as of September 30, 2003 have covenants requiring specified amounts of EBITDA, and the conversion price of the Company’s Series C Preferred Stock outstanding as of September 30, 2003 is also affected by future EBITDA.

EBITDA should not be considered an alternative to net income or loss or other measurements under accounting principles generally accepted in the United States of America as an indicator of operating performance or to cash flows from operating, investing, or financing activities as a measure of liquidity. EBITDA does not reflect working capital changes, cash expenditures for interest, income taxes, capital improvements or principal payments on indebtedness. Furthermore, the Company’s measurement of EBITDA might be inconsistent with similar measures presented by other companies.

EBITDA under the Financing Agreement, as amended, for the nine months ended September 30, 2003 is calculated as follows (dollars in thousands):

Net loss	$	(6,584	)
Cumulative effect of change in accounting principle, net of tax		8

Segment data

The following table sets forth certain operating data associated with the Company’s results of operations and summarizes EBITDA contribution by operating segment for the three and nine months ended September 30, 2003 and 2002. The Company considers EBITDA contribution from each operating segment to include revenue attributable to each segment less operating expenses, which include cost of revenues and selling, general and administrative expenses. Revenue attributable to each segment is generally external or direct revenue from third party customers. Certain income or expenses of a non-recurring or unusual nature are not included in the operating segment EBITDA contribution. This table and subsequent discussions should be read in conjunction with Item 6, “Selected Financial Data,” and Item 8, “Financial Statements and Supplementary Data” and in particular Note 19, “Segment Reporting” thereto in the Company’s Annual Report on Form 10-K and Item 1, “Financial Statements” and in particular Note 10, “Segment Reporting” thereto in this report.

Three months ended September 30, 2003 versus the three months ended September 30, 2002

Revenues

Total revenues for the three months ended September 30, 2003 increased $67.7 million to $151.1 million from $83.4 million for the comparative period in 2002. Technical Services revenues for the three months ended September 30, 2003 increased by $57.5 million to $107.5 million from $50.0 million for the comparative period in 2002. Site Services revenues for the three months ended September 30, 2003 increased $9.8 million to $44.1 million from $34.3 million for the comparative period in 2002. The increases in revenues were primarily due to the acquisition of the CSD from Safety-Kleen

The Company’s decision to integrate the operations of the former CSD into the Company’s business and financial reporting systems, combined with the replacement of the business model of the former CSD with the Company’s business model, will prevent the Company from being able to calculate meaningful changes in revenue due to volume, price or mix until after the first anniversary of the acquisition.

There are many factors which have impacted, and continue to impact, the Company’s revenues. These factors include: generally weak economic conditions, integration of operations of the former CSD, competitive industry pricing, continued efforts by generators of hazardous waste to reduce the amount of hazardous waste they produce, significant consolidation among treatment and disposal companies, industry-wide overcapacity, and direct shipment by generators of waste to the ultimate treatment or disposal location.

Cost of Revenues

Total cost of revenues for the three months ended September 30, 2003 increased $46.6 million to $108.7 million compared to $62.1 million for comparable period in 2002. Technical Services cost of revenues increased $37.2 million to $74.1 million from $36.9 million for comparable period in 2002. Site Services cost of revenues increased $7.8 million to $32.7 million from $24.9 million for comparable period in 2002. The change in cost of revenues in total and for Technical Services and Site Services are primarily a result of the CSD acquisition. As a percentage of revenues, combined cost of revenues in 2003 decreased 2.5% to 71.9% from 74.4% for comparable period in 2002. One of the largest components of cost of revenues is the cost of disposal paid to third parties. Disposal costs paid to third parties in 2003 as a percentage of revenues decreased 2.4% to 4.6% from 7.0% for comparable period in 2002. This decrease in disposal expense is due to the Company internalizing waste disposal subsequent to the acquisition that the Company sent to third parties prior to the acquisition. The Company anticipates disposal costs paid to third parties as a percentage of revenues will decrease significantly for 2003 as compared to 2002 due to the internalization of waste in the acquired end disposal facilities for the entire year 2003 as compared to the approximately four months of 2002. Other cost of revenues as a percentage of revenues decreased 0.1% to 67.3% from 67.4% for comparable period in 2002 primarily as a result of cost reductions and the resolution of certain integration issues related to the CSD acquisition.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the three months ended September 30, 2003 increased $11.5 million to $26.4 million from $14.9 million for comparable period in 2002. The increase was primarily due to the acquisition of the CSD. The change in selling, general and administrative expenses by segment is primarily a result of the CSD acquisition. The Company expects selling, general and administrative expenses in 2003 to be significantly higher than in 2002 due to the increased size of the Company since the acquisition as compared to before the acquisition.

Accretion of environmental liabilities

For the three months ended September 30, 2003 the Company recorded accretion of environmental liabilities of $2.7 million, which arose primarily from the discounting of CSD environmental liabilities under purchase accounting and the implementation of SFAS 143.

Depreciation and Amortization

Depreciation and amortization expense for the three months ended September 30, 2003 increased $2.4 million to $6.8 million from $4.4 million for comparable period in 2002. The increase was primarily due to depreciation and amortization relating to the CSD acquired assets being recorded for approximately three weeks in 2002 as compared to three months in 2003.

The Company expects depreciation and amortization expenses for the full year of 2003 to be approximately $27.0 million.

Other Income

As more fully discussed in Note 14, “Redeemable Series C Preferred Stock” in the Company’s Form 10-K as filed with the Securities and Exchange Commission on April 10, 2003, the Series C Preferred Stock consists of two components, namely (i) a non-convertible redeemable preferred stock (the “Host Contract”) which matures in September 2009, and (ii) an embedded derivative (the “Embedded Derivative”) which reflects the right of the holders to the Series C Preferred Stock to convert into the Company’s common stock. Generally accepted accounting principles in the United States require that the value of a derivative be marked to market. For the quarter ended September 30, 2003, the Company valued the Embedded Derivative using the Black-Scholes option pricing model. The Black-Scholes model determines the value of an option primarily by considering the strike price of the option, the market value of the stock and volatility of the stock. The strike price of the Embedded Derivative was $10.50 at September 30, 2003. For the quarter ended September 30, 2003, the Company recorded other income of $8.7 million primarily because of the market price decline of the Company’s common stock which occurred during that quarter. The Company believes in future periods that the value of the Embedded Derivative could increase or decrease significantly based on such factors as changes in the market value of the Company’s common stock, changes in prevailing interest rates, changes in the volatility of the Company’s common stock and changes in strike price.

Interest Expense, Net

Interest expense, net of interest income for the three months ended September 30, 2003, increased $2.7 million to $6.0 million from $3.3 million for comparable period in 2002. The increase in interest expense was due to higher average balances outstanding for the three months ended September 30, 2003 as compared to the same period in 2002, which resulted from the Company’s acquisition of the CSD assets.

Based on current interest rates and the balance of loans outstanding at September 30, 2003, the Company estimates that interest expense for 2003 will be approximately $23.5 million.

Income Taxes

Income tax expense for the three months ended September 30, 2003 decreased $0.3 million to $1.7 million from $2.0 million for comparable period in 2002. Income tax expense consists primarily of Canadian taxes of $1.6 million and $0.5 million, and federal and state income tax expense of $0.1 million and $1.5 million for the quarter ended September 30, 2003 and 2002, respectively.

In the third quarter of 2002, the Company established a $16.9 million valuation allowance on the net U.S. deferred tax assets recorded in connection with the acquisition of the CSD assets. In the same quarter, the Company established a valuation allowance for its existing net deferred assets of $1.1 million due to the difficulty posed in projecting future taxable net income due to the historic operating losses of the CSD. In the future, all reductions to the valuation allowance associated with the CSD acquisition will be recorded as a decrease to acquisition related intangible assets, rather than a benefit from income taxes.

EBITDA Contribution

The combined EBITDA contribution for the three months ended September 30, 2003 increased $9.6 million to $16.0 million from $6.4 million for comparable period in 2002. The increase in EBITDA from Technical Services contribution was $12.6 million, which was partially offset by an increase in corporate expenses of $3.1 million that related to increases to costs of the infrastructure arising from the CSD acquisition. The EBITDA contribution was flat for Site Services for the three months ended September 30, 2003 compared to the same period of the prior year. The combined EBITDA contribution is comprised of revenues of $151.1 million and $83.4 million net of cost of revenues of $108.7 million and $62.1 million and selling, general & administrative expenses of $26.4 million and $14.9 million for the three months ended September 30, 2003 and 2002, respectively.

Net Income (Loss)

The Company reported net income for the three months ended September 30, 2003 of $7.4 million compared to a loss of $33.4 million for the same period of the prior year. Net income for the three months ended September 30, 2003 contains a non-operating gain on the embedded derivative of $8.7 million discussed previously under Other Income. The loss for the same period of the prior year contains expenses relating to the acquisition of the CSD from Safety-Kleen that total $30.1 million and consist of expenses due to the early extinguishment of debt of $24.7 million, other acquisition costs of $4.7 million and restructuring and impairment of $0.7 million.

Nine months ended September 30, 2003 versus the nine months ended September 30, 2002

Revenues

Total revenues for the nine months ended September 30, 2003 increased by $268.6 million to $465.4 million from $196.8 million for the comparative period in 2002. Technical Services revenues for the nine months ended September 30, 2003 increased by $210.4 million to $320.9 million from $110.5 million for the comparative period in 2002. Site Services revenues for the nine months ended September 30, 2003 increased by $56.1 million to $143.6 million from $87.5 million for the comparative period in 2002. The Company performed one large emergency response job during the nine months ended September 30, 2003, which accounted for 12.9% of Site Services revenues for that period. The Company performed one large Site Services job in the first quarter of 2002. The job performed in 2002 related to the events of September 11, 2001 and was much lower in revenue compared to the job performed in 2003. Other than the events discussed, the increases in total revenues, Technical Services revenues and Site Services revenues were due to the acquisition of the CSD from Safety-Kleen.

Cost of Revenues

Total cost of revenues for the nine months ended September 30, 2003 increased by $204.1 million to $347.1 million compared to $143.0 million for comparable period in 2002. Technical Services cost of revenues increased by $150.8 million to $229.0 million from $78.2 million for comparable period in 2002. Site Services cost of revenues increased by $45.0 million to $108.5 million from $63.5 million for comparable period in 2002. The change in cost of revenues in total and for Technical Services and Site Services are primarily a result of the CSD acquisition. As a percentage of revenues, combined cost of revenues in 2003 increased 1.9% to 74.6% from 72.7% for comparable period in 2002. One of the largest components of cost of revenues is the cost of disposal paid to third parties. Disposal costs paid to third parties in 2003 as a percentage of revenues decreased 4.3% to 4.8% from 9.1% for comparable period in 2002. This decrease in disposal expense is due to the Company internalizing waste disposal subsequent to the acquisition that the Company sent to third parties prior to the acquisition. The Company anticipates disposal costs paid to third parties as a percentage of revenues will decrease significantly for 2003 as compared to 2002 due to the internalization of waste in the acquired end disposal facilities for the entire year 2003 as compared to the approximately four months of 2002. Other costs of revenues as a percentage of revenues increased 6.2% to 69.8% from 63.6% for comparable period in 2002 primarily as a result of reduced facility utilization due to the level of waste processed which is due to the general economic environment and the fixed cost nature of the facilities. Included in cost of revenues for the first nine months of 2003 is approximately $1.5 million of increased health insurance expense due to higher than anticipated costs for the Company’s self-insured health plan.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the nine months ended September 30, 2003 increased by $47.7 million to $84.5 million from $36.8 million for comparable period in 2002. The increase was primarily due to the acquisition of the CSD. The change in selling, general and administrative expenses by segment is primarily a result of the CSD acquisition. The Company expects selling, general and administrative expenses in 2003 to be significantly higher than in 2002 due to the increased size of the Company since the acquisition as compared to before the acquisition. Included in selling, general and administrative for the first nine months of 2003 is approximately $1.5 million of increased health insurance expense due to higher than anticipated costs for the Company’s self-insured health plan.

Accretion of environmental liabilities

For the nine months ended September 30, 2003 the Company recorded accretion of environmental liabilities of $8.3 million, which arose primarily from the discounting of CSD environmental liabilities under purchase accounting and the implementation of SFAS 143.

Depreciation and Amortization

Depreciation and amortization expense for the nine months ended September 30, 2003 increased by $10.2 million to $19.9 million from $9.7 million for comparable period in 2002. The increase was primarily due to depreciation and amortization arising from the acquisition of the CSD assets.

Other Income

Interest Expense, Net

Interest expense, net of interest income for the nine months ended September 30, 2003, increased $9.5 million to $17.5 million from $8.0 million for comparable period in 2002. The increase in interest expense was due to higher average balances outstanding for the nine months ended September 30, 2003 as compared to the same period in 2002, which resulted from the Company’s acquisition of the CSD assets.

Income Taxes

Income tax expense for the nine months ended September 30, 2003 increased by $1.8 million to $4.0 million from 2.2 million for comparable period in 2002. Income tax expense consists primarily of Canadian taxes of $3.7 million and $0.5 million and federal and state income tax expense of $0.3 million and $1.7 million for the nine months ended September 30, 2003 and 2002 respectively.

In the third quarter of 2002, the Company established a $16.9 million valuation allowance on the net U.S. deferred tax assets recorded in connection with the acquisition of the CSD assets. In the same quarter, the Company established a valuation allowance for its existing net deferred assets of $1.1 million due to the difficulty posed in projecting future taxable net income due to the historic operating losses of the CSD. In the future, all reductions to the valuation allowance associated with the CSD acquisition will be recorded as a decrease to acquisition related intangible assets, rather than a benefit from income taxes.

EBITDA Contribution

The combined EBITDA contribution by segment for the nine months ended September 30, 2003 increased by $16.8 million to $33.8 million from $17.0 million for the comparable period in 2002. The increase from Technical Services was $29.1 million and from Site Services was $5.3 million, which were partially offset by an increase in corporate expense items of $17.6 million that related to increases to costs of the infrastructure arising from the CSD acquisition. The combined EBITDA contribution is comprised of revenues of $465.4 million and $196.8 million net of cost of revenues of $347.1 million and $143.0 million and selling, general & administrative expenses of $84.5 million and $36.8 million for the nine months ended September 30, 2003 and 2002, respectively.

Net Income (Loss)

The Company reported a net loss for the nine months ended September 30, 2003 of $6.6 million compared to a loss of $33.1 million for the same period of the prior year. The net loss for the nine months ended September 30, 2003 was reduced by the $9.2 million non-operating gain on the embedded derivative discussed previously under other income. The loss for the same period of the prior year contains expenses relating to the acquisition of the CSD from Safety-Kleen that total $30.1 million and consists of expenses due to the early extinguishment of debt of $24.7 million, other acquisition costs of $4.7 million and restructuring and impairment of $0.7 million.

Factors that May Affect Future Results

In addition to “Factors that May Affect Future Results” in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s Form 10-K as filed with the Securities and Exchange Commission on April 10, 2003, presented below is an additional factor that investors should consider with respect to an investment in the Company’s securities. Investors should be aware that there are various risks, including those described below, which may materially impact on investment in the Company’s securities or may in the future, and, in some cases, already do, materially affect the Company and its business, financial condition and results of operations. This section includes or refers to certain forward-looking statements; investors should read the explanation of the qualifications and limitations on such forward-looking statements discussed on page 31 of this report.

As discussed below under “Liquidity and Capital Resources,” the Company negotiated amendments to its financing agreements due to loan covenant violations that included resetting the loan covenants to levels the Company believes it will be able to meet in the future. No assurance can be given that the Company will be able to meet the loan covenants in the future or that the Company will be able to obtain waivers from the lenders if the loan covenants are violated in the future. Violating the loan covenants in future periods could result a significant decrease in the value of the Company’s stock.

Liquidity and Capital Resources

Cash and Cash Equivalents

The Company’s primary sources of liquidity are cash flows from operations, existing cash and the Revolving Credit Facility (as hereinafter defined). As of September 30, 2003, cash and cash equivalents was $6.1 million, and $35.7 million had been drawn on the Revolving Credit Facility.

The Company intends to use its existing cash and cash flow from operations to fund future operating expenses and recurring capital expenditures. The Company anticipates that cash flow provided by operating activities will provide the necessary funds on a short and long-term basis to meet operating cash requirements. As part of the CSD acquisition, the Company assumed environmental liabilities of CSD valued in accordance with generally accepted accounting principles of $184.5 million. The Company performed extensive due diligence investigations with respect to both the amount and timing of such liabilities. The Company anticipates such liabilities will be payable over many years and that cash flow from operations will generally be sufficient to fund the payment of such liabilities when required. However, events not now anticipated (such as future changes in environmental laws and regulations) could require that such payments be made earlier or in greater amounts than now anticipated, which could adversely affect the Company’s cash flow and financial condition.

Cash Flows for the nine months ended September 30, 2003

For the nine months ended September 30, 2003, the Company generated $29.9 million of cash from operating activities. The Company recorded non-cash expenses for the nine months ended September 30, 2003, which provided sources of funds totaling $31.6 million. These non-cash expenses consisted primarily of $19.9 million for depreciation and amortization, $8.3 million for the accretion of environmental liabilities, $1.7 million for the amortization of deferred financing costs and $1.4 million for allowance for doubtful accounts. Other sources of cash totaled $29.9 million and consisted primarily of the $20.6 million decrease in accounts receivable which was due to successfully reducing the days sales outstanding of accounts receivable through enhanced collection efforts, the $3.1 million decrease in unbilled accounts receivable which was accomplished by resolving certain integration issues related to the CSD acquisition and the $3.5 million decrease in prepaid expenses. Partially offsetting the sources of cash were uses of cash which consist of the $6.6 million net loss for the period, the $9.2 million non-cash gain on the embedded derivative, and other uses of cash that totaled $15.8 million which consist primarily of a decrease in deferred revenue of $5.5 million due primarily to operational improvements realized in the integration of the CSD into the Company’s operations, a decrease in environmental liabilities of $6.0 million and an increase in other assets of $1.4 million.

For the nine months ended September 30, 2003, the Company used $44.5 million of cash in investing activities. Cash used in investing activities consists of the cost of restricted investment purchases of $34.2 million to support the letters of credit issued relating to financial assurance for closure and post-closure obligations and additions to property, plant and equipment and permits of $25.8 million. These uses were partially offset by proceeds from the reduction of restricted investments of $5.8 million.

For the nine months ended September 30, 2003, the Company obtained $6.3 million of cash from financing activities. Sources of cash from financing activities totaled $18.6 million and consist primarily of net borrowings under the revolving credit facility of $17.8 million. Partially offsetting sources of cash from financing activities were uses of cash from financing activities that totaled $12.3 million. The largest use of cash was repayments on the Senior Loan that totaled $7.5 million which was obtained from the Company negotiating a reduction in the amount of restricted cash required as collateral for letters of credit to support financial assurance for closure and post-closure care of the Company’s facilities and proceeds from the sale of fixed assets. Other significant uses of cash included $1.8 million due to a decrease in the amount uncashed checks relating to the Company’s cash management program and $1.6 million due to deferred financing costs incurred.

The Company used the sources of cash from financing activities of $6.3 million together with the $29.9 million of cash generated from operations and a decrease in the amount of cash on-hand of $7.6 million primarily to fund the investing activities of $44.5 million previously discussed.

Financing Arrangements

The principal terms of the Revolving Credit Facility, the Senior Loans, the Subordinated Loans, and the L/C Facility are as follows:

The Revolving Credit Facility provides for certain covenants the most restrictive of which required that the Company maintain minimum consolidated annualized earnings before interest, income taxes, depreciation and amortization (“EBITDA”), see “Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) in Item 2 of this report titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for a discussion about the non-GAAP measure EBITDA, of not less than $15.7 million for the fiscal quarter ended September 30, 2003. For the quarter ended September 30, 2003, EBITDA was (as described below) $16.0 million which was within covenant. The Company was also required to maintain an annualized rolling fixed charge coverage ratio of not less than 0.85 to 1.0 for the fiscal quarter ended September 30, 2003. At September 30, 2003, the fixed charge coverage ratio was 1.0 to 1.0 which was within covenant.

Net income	$	7,418
Accretion of environmental liabilities		2,745
Depreciation and amortization		6,787
Interest expense, net		6,048
Provision for income taxes		1,746
Change in value of embedded derivative		(8,748	)

EBITDA	$	15,996

L/C Facility. At September 30, 2003, letters of credit outstanding under the L/C Facility were $85.9 million.

Stockholder Matters

In 2003, the Company issued 1,236,010 shares of common stock in exchange for 1,236,916 warrants that were then terminated and that were issued relating to the April 2001 issuance of the $35 million Subordinated Notes. No such warrants remain outstanding.

Dividends on the Company’s Series B Convertible Preferred Stock are payable on the 15th day of January, April, July and October, at the rate of $1.00 per share, per quarter; 112,000 shares are outstanding. Under the terms of the Series B Preferred Stock, the Company can elect to pay dividends in cash or in common stock with a market value equal to the amount of the dividend payable. For 2003 the January 15 and April 15 dividends and for 2002 the January 15, April 15 and July 15 dividends on the Series B Preferred Stock were paid in cash. However, because of the amendment to the Company’s Financing Agreement which became effective in May 2003, the Company issued for the July 15, 2003 dividend 11,581 shares of the Company’s common stock in lieu of a cash dividend. The Company anticipates that dividends on the Series B Preferred Stock will be paid in common stock for the foreseeable future.

New Accounting Pronouncements

In July 2001, the FASB issued SFAS No. 143, “Accounting for Asset Retirement Obligations.” SFAS No. 143 requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. When a liability is initially recorded, the entity capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement. The standard is effective for fiscal years beginning after June 15, 2002. The Company adopted SFAS No. 143 in the first quarter of 2003 (see Note 7, “Remedial Liabilities and Change in Accounting for Asset Retirement Obligations,” to the financial statements included in Item 1 of this report).

In April 2002, the FASB issued SFAS No. 145, “Rescission of FASB Statement No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections.” SFAS No. 145 rescinds SFAS No. 4, “Reporting Gains and Losses from Extinguishment of Debt,” and an amendment of that SFAS No. 64, “Extinguishment of Debt made to satisfy Sinking-Fund Requirements.” This Statement also rescinds SFAS No. 44, “Accounting for Intangible Assets of Motor Carriers.” This SFAS amends SFAS No. 13, “Accounting for Leases,” to eliminate an inconsistency between the required accounting for sale-leaseback transactions and the required accounting for certain lease modifications that have economic effects that are similar to sale-leaseback transactions. This Statement also amends other existing authoritative pronouncements to make various technical corrections, clarify meaning, or describe their applicability under changed conditions. SFAS No. 145 is effective for fiscal years beginning after May 15, 2002. The Company has determined the adoption of SFAS No. 145 will result in the reclassification of the extraordinary loss related to early extinguishment of debt of $24,658,000, recorded in the quarter ended September 30, 2002, to other expenses in arriving at its income or loss from operations for that period. The Company believes the adoption of SFAS No. 145 did not materially affect the Company’s financial condition.

In July 2002, the FASB issued SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities”. SFAS No. 146 requires companies to recognize costs associated with exit or disposal activities when they are incurred rather than at the date of a commitment to exit or disposal plan. Examples of costs covered by the standard include lease termination costs and certain employee severance costs that are associated with a restructuring, discontinued operation, plant closing, or other exit or disposal activity. SFAS No. 146 is to be applied prospectively to exit or disposal activities initiated after December 31, 2002. Adoption of SFAS No. 146 as of January 1, 2003 had no impact on results of operations or financial condition for the three and nine months ended September 30, 2003.

In January 2003, the FASB issued FASB Interpretation No. 46 (“FIN 46”), “Consolidation of Variable Interest Entities.” FIN 46 requires that unconsolidated variable interest entities must be consolidated by their primary beneficiaries. A primary beneficiary is the party that absorbs a majority of the entity’s expected losses or residual benefits. In October 2003, the FASB issued FASB Staff Position (“FSP”) 46-6, “Effective Date of FASB Interpretation No. 46, Consolidation of Variable Interest Entities” (“VIE”) which delays the effective date of FIN 46 to December 15, 2003 for certain VIE’s. The adoption of FIN 46 had no impact on the results of operations or financial condition for the periods ending September 30, 2003.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is subject to market risk on the interest that it pays on its debt due to changes in the general level of interest rates. The Company’s philosophy in managing interest rate risk is to borrow at fixed rates for longer time horizons to finance non-current assets and to borrow at variable rates for working capital and other short term needs. The following table provides information regarding the Company’s fixed rate borrowings at September 30, 2003 (dollars in thousands):

Scheduled Maturity Dates	Three Months Remaining 2003			2004			2005			2006			2007			Thereafter			Total
Subordinated Loans	$	—		$	—		$	—		$	—		$	40,000		$	—		$	40,000
Redeemable Convertible Preferred Stock		—			—			—			—			—			36,673			36,673
Capital Lease Obligations		247			1,015			978			891			620			80			3,831

	$	247		$	1,015		$	978		$	891		$	40,620		$	36,753		$	80,504

Weighted average interest rate on fixed rate borrowings		15.2	%		15.4	%		15.3	%		15.2	%		11.2	%		6.0	%

In addition to the fixed rate borrowings described in the table above, the Company had at September 30, 2003 borrowings at variable interest rates of $107.5 million that bore interest at LIBOR (1.14% at September 30, 2003) plus 7.75%, and borrowings of $35.7 million that bore interest at either the U.S. “prime” rate (4.00% at September 30, 2003) plus 0.50% or the Canadian “prime” rate (4.75% at September 30, 2003) plus 0.50%. The following table presents hypothetical situations of the amount of interest expense that would be incurred on an annual basis assuming the balance outstanding at September 30, 2003 remained unchanged and assuming three scenarios for interest rates: (i) interest rates remain unchanged from those on September 30, 2003, (ii) interest rates increase by 200 basis points and (iii) interest rates decrease by 200 basis points (dollars in thousands):

Description of Debt	Principal Balance September 30, 2003		Interest if Interest Rates Remain Unchanged		Interest if Interest Rates Increase 200 b.p.		Interest if Interest Rates Decrease 200 b.p.
Senior Loans	$	107,502	$	9,557	$	11,234	$	6,934
Revolving Credit Facility		35,731		1,646		2,361		931

	$	143,233	$	11,203	$	13,595	$	7,865

Historically, the Company has not entered into derivative or hedging transactions, nor has the Company entered into transactions to finance debt off of its balance sheet. The Company views its investment in the Canadian subsidiaries as long-term; thus, the Company has not entered into any hedging transactions between the Canadian dollar and the U.S. dollar. The Canadian subsidiaries transact approximately 25% of their business in U.S. dollars and at any period end have cash on deposit in U.S. dollars and outstanding U.S. dollar accounts receivable related to these transactions. These cash and receivable accounts are subject to foreign currency translation gains or losses. During the three and nine months ended September 30, 2003, as compared to the same periods ended September 30, 2002, the U.S. dollar fell approximately 0.4% and 17.0%, respectively, against the Canadian dollar resulting in foreign currency losses of $0.1 million and $2.3 million, respectively. The Company is subject to minimal market risk arising from purchases of commodities since no significant amount of commodities are used in the treatment of hazardous waste.

As more fully described in Note 14, Redeemable Series C Preferred Stock, in the Company’s 10-K as filed with the Securities and Exchange Commission for the year ended December 31, 2002, the Company issued Series C Preferred Stock $0.01 par value (the “Series C Preferred Stock”) for $25,000,000 on September 10, 2002, and incurred $2,891,000 of issuance costs. The Company has determined that the Series C Preferred Stock should be recorded on the Company’s financial statements as though the Series C Preferred Stock consists of two components, namely (i) a non-convertible redeemable preferred stock (the “Host Contract”) which matures in seven years with a 6% annual dividend, and (ii) an embedded derivative (the “Embedded Derivative”) which reflects the right of the holders of the Series C Preferred Stock to convert into the Company’s common stock on the terms set forth in the Series C Preferred Stock. The initial values of these two components were determined as of the issuance date based upon relative fair values using a discounted cash flow model and an assumed rate of return of 14%. Accordingly, the Series C Preferred Stock was discounted to arrive at fair value of $15,677,000 for the Host Contract with the remaining cash proceeds received at issuance of $9,323,000 assigned as the fair value of the Embedded Derivative. The Company recorded in Other Long-term Liabilities the $9,323,000 initial fair value of the Embedded Derivative and will periodically mark that value to market until such time as the maximum number of shares of common stock, which may be issued upon conversion of the Series C Preferred Stock is determined. As of September 30, 2003, the market value of the Embedded Derivative was determined to have no value and the Company recorded $8.7 million and $9.2 million of other income for the three and nine months September 30, 2003, respectively, to reflect such adjustment. The Company believes in future periods that the value of the Embedded Derivative could increase or decrease significantly based on such factors as changes in the market value of the Company’s common stock, changes in prevailing interest rates and changes in the volatility of the Company’s common stock.

ITEM 4. CONTROLS AND PROCEDURES

Since the acquisition of the assets of the Chemical Services Division (the “CSD”) of Safety-Kleen Corp. (“Safety-Kleen”) effective September 7, 2002 (see Note 2 to the financial statements included in this report), the Company has focused upon integrating the operations acquired into the Company’s disclosure controls and procedures and internal controls. Safety-Kleen has publicly disclosed that it has historically had material deficiencies in many of its financial systems, processes and related internal controls. Due to the deficiencies in these systems and the Company’s belief that it will be able to utilize its own systems in order to improve the operations of the former CSD, the decision was made to integrate the United States operations of the former CSD into the Company’s business and financial reporting systems effective as of the acquisition date. As anticipated, the Company has experienced certain systems and efficiency issues during the initial period of the integration. The Company has made significant progress in integrating the CSD into the Company’s business and financial reporting systems and believes that all major systems for operations within the United States and certain systems in Canada were substantially integrated and operating efficiently as of September 30, 2003. During the integration process, the Company identified the need for various enhancements to address needs that are unique to the CSD business and to improve system efficiencies and security. In addition, the significant increase in transaction volume, as well as the significant increase in the number of new users of the Company’s systems, increases the risk of human error or mistake during the integration period. Likewise, the acquisition and integration of a business much larger in size and scope of operations increases the risk that conditions may have been introduced that the Company’s design of its systems of control have not anticipated. The Company’s decision to integrate the operations of the former CSD into the Company’s business and financial reporting systems, combined with the replacement of the business model of the former CSD with the Company’s business model, will prevent the Company from being able to calculate meaningful changes in revenue due to volume, price or mix until after the first anniversary of the acquisition. Furthermore, Safety-Kleen’s pre-existing deficiencies in financial systems, processes and related internal controls increase the risk that the historical unaudited financial statements of the CSD’s operations and cash flows which Safety-Kleen has provided to the Company are not accurate. Prior to the acquisition, the Company conducted extensive due diligence investigations with respect to the operations and cash flows of the CSD; however, there is a risk due to the material deficiencies in Safety-Kleen’s internal controls that undetected errors may exist in the financial statements provided by Safety-Kleen.

The Company does not expect that its disclosure controls and procedures or its internal controls will prevent all errors and all fraud. “Internal controls” are procedures which are designed with the objective of providing reasonable assurance that (1) transactions are properly authorized; (2) assets are safeguarded against unauthorized or improper use; and (3) transactions are properly recorded and reported, all so as to permit the preparation of financial statements in conformity with generally accepted accounting principles. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. In addition, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

In October 2002, the Company established a Disclosure Committee pursuant to the provisions of the Sarbanes-Oxley Act. The Committee is chaired by the Company’s General Counsel and consists of the Company’s Chief Executive Officer, Chief Financial Officer, Corporate Controller, Senior Vice President of Risk Management and the vice president responsible for oversight of the environmental liabilities associated with discontinued facilities and operations. From time to time the Committee also confers with two outside consultants, one an expert in investor relations and the other an attorney specializing in SEC matters.

In connection with the audit for the year ended December 31, 2002, PricewaterhouseCoopers LLP (“PwC”) advised the Audit Committee of the Company’s Board of Directors, and the then Chief Financial Officer and the Corporate Controller advised the Disclosure Committee, that during the course of the audit of the Company’s financial statements for the year ended December 31, 2002, they noted material weaknesses in internal controls relating to the documentation and the retention of documentation for the environmental liabilities, material weaknesses in internal controls for the process of calculating deferred revenue, and material weaknesses in internal controls over recording expenses in the appropriate period. Also, reportable conditions exist for valuation of supplies inventory and security over significant financial systems.

Most of the deficiencies were introduced with the CSD acquisition. The Company has observed steady improvement during the months subsequent to the acquisition and anticipates further natural additional improvements as the new users of the Company’s systems become more experienced and key data elements transferred from the old CSD systems are replaced with more current and accurate information from transactions processed through the Company’s systems. In addition, the Company intends to create a new function headed by a senior manager focused on assessment and remediation of internal controls and procedures for financial reporting.

The Chief Financial Officer and Corporate Controller have advised the Audit Committee and the Disclosure Committee that the Company has performed substantial additional procedures designed to ensure that these internal control deficiencies do not lead to material misstatements in its Consolidated Financial Statements, notwithstanding the presence of the internal control weaknesses noted above.

In light of this information, within the 90 days prior to the filing date of this report, the Company’s Disclosure Committee carried out an evaluation, with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures pursuant to the Securities Exchange Act Rule 13a-15. “Disclosure controls and procedures” are controls and procedures that are designed to ensure that information required to be disclosed by the Company in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that while the Company’s disclosure controls and procedures are substantially effective for these purposes as of the date of the evaluation, the Company should continue its efforts to further improve its disclosure controls and procedures.

There have been no significant changes in the Company’s internal controls or in other factors that could significantly affect these controls subsequent to the date of their evaluation, other than the ongoing actions described above, many of which were begun prior to the most recent evaluation date.

THIRD AMENDMENT TO

FINANCING AGREEMENT

THIS THIRD AMENDMENT TO FINANCING AGREEMENT (this “Amendment”) is entered into as of October 31, 2003, by and among Clean Harbors, Inc., a Massachusetts corporation (the ”Parent”), each subsidiary of the Parent listed as a “Borrower” on the signature pages to the Financing Agreement (together with the Parent, each a “Borrower” and collectively, the “Borrowers”), each subsidiary of the Parent listed as a “Guarantor” on the signature pages to the Financing Agreement (each a “Guarantor” and collectively, the “Guarantors”; together with the Borrowers, the “Loan Parties”), the financial institutions from time to time party to the Financing Agreement (each a “Lender” and collectively, the “Lenders”), and Ableco Finance LLC, a Delaware limited liability company (“Ableco”), as agent for the Lenders (in such capacity, the “Agent”).

W I T N E S S E T H

WHEREAS, the Loan Parties, the Lenders and the Agent are parties to a Financing Agreement, dated as of September 6, 2002 (as amended, modified or supplemented from time to time, the “Financing Agreement”), pursuant to which the Lenders have made certain terms loans to the Borrowers in an aggregate principal amount at any time not to exceed the aggregate amount of the Commitments (as defined in the Financing Agreement) set forth therein;

WHEREAS, the Loan Parties, the Lenders and the Agent desire to amend certain terms and provisions of the Financing Agreement as set forth herein;

WHEREAS, the Agent and the Lenders are willing to amend the Financing Agreement to provide for such amendments, subject to the execution and delivery of this Amendment by the Loan Parties; and

NOW, THEREFORE, in consideration of the premises and of the mutual covenants, agreements and conditions hereinafter set forth, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1. Capitalized Terms. All capitalized terms used in this Amendment and not otherwise defined shall have their respective meanings set forth in the Financing Agreement.

2. Fixed Charge Coverage Ratio. The definition of the term “Fixed Charge Coverage Ratio” set forth in Section 1.01 of the Financing Agreement is hereby amended by inserting the following proviso at the end of clause (ii)(E) thereof:

“, provided that for the purposes of this clause (E), for the fiscal quarters ending on each of September 30, 2003, December 31, 2003, March 31, 2004 and June 30, 2004, Capital Expenditures shall exclude any amounts resulting from the reallocation of certain accounts relating to purchase accounting entries and accruals on the statement of cash flows of the Parent and its Subsidiaries for the six-month period ending on June 30, 2003 pursuant to which such accounts were netted from fixed asset

accounts and, provided, further, that such reallocations shall have no impact on the balance sheet or the statement of operations of the Parent and its Subsidiaries for any period.”

3. Conditions to Effectiveness. This Amendment shall become effective only upon satisfaction in full, in a manner satisfactory to the Agent, of the following conditions precedent (the first date upon which all such conditions shall have been satisfied being herein called the “Amendment Effective Date”):

(a) The representations and warranties contained in Article VI of the Financing Agreement and in each other Loan Document, certificate or other writing delivered on or on behalf of any Loan Party to the Agent or any Lender pursuant to the Financing Agreement or any other Loan Document on or prior to the Amendment Effective Date are true and correct on and as of such date as though made on and as of such date, and hereof, no Default or Event of Default has occurred and is continuing on the Amendment Effective Date or would result from this Amendment becoming effective in accordance with its terms.

(b) The Agent shall have received on or before the Amendment Effective Date counterparts to this Amendment signed by each of the Loan Parties, the Lenders and the Agent, in form and substance satisfactory to the Agent and dated the Amendment Effective Date.

4. Representations and Warranties. Each Loan Party that is a party to the Financing Agreement hereby represents and warrants to the Agent and the Lenders as follows:

(a) Representations and Warranties; No Event of Default. The representations and warranties herein, in Article VI of the Financing Agreement and in each other Loan Document, certificate or other writing delivered on or on behalf of any Loan Party to the Agent or any Lender pursuant to the Financing Agreement or any other Loan Document on or prior to the Amendment Effective Date are true and correct on and as of such date as though made on and as of such date, and no Default or Event of Default has occurred and is continuing as of the Amendment Effective Date or would result from this Amendment becoming effective in accordance with its terms.

(b) Organization, Good Standing, Etc. Each Loan Party (i) is a corporation, limited liability company or limited partnership duly organized, validly existing and in good standing under the laws of the state or jurisdiction of its organization, (ii) has all requisite power and authority to conduct its business as now conducted and as presently contemplated, and to execute and deliver this Amendment, and to consummate the transactions contemplated hereby and by the Financing Agreement, as amended hereby, and (iii) is duly qualified to do business and is in good standing in each jurisdiction in which the character of the properties owned or leased by it or in which the transaction of its business makes such qualification necessary, except where the failure to be so qualified and in good standing could not reasonably be expected to have a Material Adverse Effect.

(c) Authorization, Etc. The execution, delivery and performance of this Amendment and each other Loan Document being executed in connection with this Amendment by each Loan Party that is a party thereto, and the performance of the Financing Agreement as amended hereby (i) have been duly authorized by all necessary action, (ii) do not and will not contravene such Loan Party’s charter or by-laws, its limited liability company or operating agreement or its certificate of partnership or partnership agreement, as applicable, or any applicable law or any Transaction Document, any Material Contract or any other contractual restriction binding on or otherwise affecting it or any of its properties, (iii) do not and will not result in or require the creation of any Lien (other than pursuant to any Loan Document) upon or with respect to any of its properties, and (iv) do not and will not result in any default, noncompliance, suspension, revocation, impairment, forfeiture or nonrenewal of any permit, license, authorization or approval applicable to its operations or any of its properties.

(d) Governmental Approvals. No authorization or approval or other action by, and no notice to or filing with, any Governmental Authority is required in connection with the due execution, delivery and performance by any Loan Party of this Amendment or any other Loan Document to which it is a party being executed in connection with this Amendment, or for the performance of the Financing Agreement, as amended hereby.

(e) Enforceability of Loan Documents. Each of this Amendment, the Financing Agreement, as amended hereby, and each other Loan Document to which such Loan Party is a party is a legal, valid and binding obligation of such Loan Party, enforceable against such Loan Party in accordance with its terms, except as may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws.

5. Continued Effectiveness of Financing Agreement. Each Loan Party hereby (i) confirms and agrees that each Loan Document to which it is a party is, and shall continue to be, in full force and effect and is hereby ratified and confirmed in all respects except that on and after the Amendment Effective Date all references in any such Loan Document to “the Financing Agreement”, “thereto”, “thereof”, “thereunder” or words of like import referring to the Financing Agreement shall mean the Financing Agreement as amended by this Amendment, and (ii) confirms and agrees that to the extent that any such Loan Document purports to assign or pledge to the Agent, or to grant to the Agent, a Lien on any collateral as security for the Obligations of the Borrowers from time to time existing in respect of the Financing Agreement and the Loan Documents, such pledge, assignment and/or grant of a Lien is hereby ratified and confirmed in all respects.

6. Miscellaneous.

(a) This Amendment 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.

(b) Section and paragraph headings herein are included for convenience of reference only and shall not constitute a part of this Amendment for any other purpose.

(d) Each Loan Party hereby acknowledges and agrees that this Amendment constitutes a “Loan Document” under the Financing Agreement. Accordingly, it shall be an Event of Default under the Financing Agreement if (i) any representation or warranty made by a Loan Party under or in connection with this Amendment shall have been untrue, false or misleading in any material respect when made, or (ii) a Loan Party shall fail to perform or observe any term, covenant or agreement contained in this Amendment.

(e) Notwithstanding anything to the contrary, except as specifically provided herein, this Amendment is not, and shall not be deemed to be, a waiver of, or a consent to any Event of Default, event with which the giving of notice or lapse of time or both may result in an Event of Default, or other noncompliance now existing or hereafter arising under the Financing Agreement and the other Loan Documents.

7. The Borrowers will pay on demand all reasonable out-of-pocket costs and expenses of the Agent and the Lenders in connection with the preparation, execution and delivery of this Amendment, including, without limitation, the reasonable fees, disbursements and other charges of Schulte Roth & Zabel LLP, counsel to the Agent.

8. THE LOAN PARTIES, THE AGENT AND THE LENDERS EACH HEREBY IRREVOCABLY WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AMENDMENT OR THE ACTIONS OF THE AGENT OR THE LENDERS IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF.
