CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Basis of Presentation

The accompanying consolidated interim financial statements include the accounts of Clean Harbors, Inc. and its wholly-owned subsidiaries (collectively, “Clean Harbors” or the “Company”) and have been prepared 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, 2003.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 cubic 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 every three years. 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.

Certain reclassifications have been made in the prior periods’ Consolidated Financial Statements to conform to the presentation for the three- and nine-month periods ended September 30, 2004.

(2) Acquisition

As more fully described in the Annual Report on Form 10-K for the year ended December 31, 2003, 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”), effective September 7, 2002. 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.

In accordance with the Acquisition Agreement between the Seller and the Company dated February 22, 2002, as amended through September 6, 2002, the Company purchased the assets of the CSD for $26.6 million in net cash, and incurred direct costs related to the transaction of $9.7 million for a total purchase price of $36.3 million. In addition, the Company assumed with the transaction certain environmental liabilities valued at $184.5 million.

In connection with the acquisition of the CSD assets, the Company recorded integration liabilities of $12.6 million (after giving effect to subsequent net changes in estimates) which consisted primarily of 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 (dollars in thousands):

	Severance					Facilities

(3) Significant Accounting Policies

(a) New Accounting Pronouncements

In January 2003, the Financial Accounting Standards Board (“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. FIN 46 applies immediately to variable interest entities created after January 31, 2003. In December 2003, the FASB issued FIN 46-R. FIN 46-R deferred to March 15, 2004 the effective date for variable interest entities created before January 31, 2003. FIN 46 and FIN 46-R will have no impact on the Company’s results of operations since it has no variable interest entities.

(b) Stock Options

The Company applies Accounting Principles Board (“APB”) Opinion No. 25 and related Interpretations in accounting for its stock-based employee compensation plans. Statement of Financial Accounting Standards (“SFAS”) No. 123, “Accounting for Stock-Based Compensation” 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 No. 123, the Company’s net income (loss) and net earnings (loss) per common share for the three- and nine-month periods ended September 30, 2004 and 2003, would approximate the pro forma amounts as compared to the amounts reported (in thousands except for per share amounts):

	Three Months Ended September 30,					Nine Months Ended September 30,
	2004		2003			2004			2003

Diluted pro forma	$	0.22	$	(0.13	)	$	(1.29	)	$	(1.11	)

(4) Restricted Cash

At September 30, 2004 and December 31, 2003, restricted cash consisted of the following (in thousands):

	September 30, 2004		December 31, 2003

Cash collateral for letter of credit facility – current	$	381	$	—
Cash collateral for letter of credit facility – non-current	—		88,817
	$	381	$	88,817

Operators of hazardous waste handling facilities are required by federal and state regulations to provide financial assurance for closure and post-closure care of those facilities should those facilities cease operation. Closure would include the cost of removing the waste stored at the facility which ceased operating, sending such material to another site for disposal, and performing certain procedures for decontamination of the facility. The Company has placed most of the required financial assurance through Steadfast Insurance Company, which requires letters of credit as collateral to its financial assurance obligations. At December 31, 2003, the Company had a Letter of Credit Facility (the “L/C Facility”) under an Agreement dated September 6, 2002 between the Company and Fleet National Bank (“Fleet”). The L/C Facility Agreement provided that Fleet would issue up to $100.0 million of letters of credit at the Company’s request provided that the Company posted collateral equal to 103% of the amount of the outstanding letters of credit. As further discussed in Note 6, “Financing Arrangements,” on June 30, 2004, the L/C Facility was replaced with a synthetic letter of credit facility (the “Synthetic LC Facility”). Under the Synthetic LC Facility, the Company is not required to post cash collateral. On June 30, 2004, the $88.9 million of restricted cash then on deposit was released to the Company.

As described in the Annual Report on Form 10-K for the year ended December 31, 2003, the Company previously had a $100.0 million revolving credit facility (the “Revolving Credit Facility”) that allowed the Company to borrow up to $100.0 million in cash and letters of credit with Congress Financial Corporation (“Congress”). On June 30, 2004, the Company posted $3.9 million of restricted cash with Congress to support $3.6 million of letters of credit then outstanding that for administrative reasons could not be replaced with letters of credit under the Synthetic LC Facility as discussed in Note 6 “Financing Arrangements.” During the third quarter of 2004, almost all of the $3.6 million of letters of credit outstanding at June 30, 2004 with Congress were replaced with letters of credit under the Synthetic LC Facility which resulted in the release of restricted cash for the Company’s general use of $3.5 million in the quarter ended September 30, 2004. The Company anticipates that by December 31, 2004 the remaining letters of credit outstanding with Congress will be replaced with other letters of credit, allowing the $0.4 million of restricted cash at September 30, 2004 to be released for the Company’s general use.

(5) Properties Held for Sale

As part of its plan to integrate the activities of the CSD into its operation, the Company determined that certain acquired properties were no longer needed for its 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. In addition, subsequent to the completion of purchase accounting, the Company identified several additional properties that were no longer needed for its operations. These properties were transferred to properties held for sale at the lower of their net book value or 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. The Company cannot provide assurance that the proceeds from properties held for sale will equal their carrying value.

During the three month period ended March 31, 2004, the Company sold one of the properties for $0.6 million, net of selling costs. The gain on the sale of approximately $0.2 million is included in other income (expense).

As described in the Annual Report on Form 10-K for the year ended December 31, 2003, the Company previously had outstanding a $100.0 million three-year revolving credit facility (the “Revolving Credit Facility”), $115.0 million 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 had established a letter of credit facility (the “L/C Facility”) under which the Company could 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. On June 30, 2004, the Company’s debt under the Revolving Credit Facility, the Senior Loans and the Subordinated Loans was replaced by $150.0 million of eight-year Senior Secured Notes (the “Senior Secured Notes”) and a $30.0 million revolving credit facility (the “Revolving Facility”) as described below. Additionally, the L/C Facility was replaced with a synthetic letter of credit facility (the “Synthetic LC Facility”) whereby the Company may obtain up to $90.0 million of letters of credit as described below.

The principal terms of the Senior Secured Notes, the Revolving Facility, and the Synthetic LC Facility are as follows:

Senior Secured Notes. The Senior Secured Notes were issued under an Indenture dated June 30, 2004 (the “Indenture”). The Senior Secured Notes bear interest at 11.25% and mature on July 15, 2012. The Senior Secured Notes were issued at a $2.0 million discount that results in an effective yield of 11.5%. Interest is payable semiannually in cash on each January 15 and July 15, commencing on January 15, 2005.

The Senior Secured Notes are secured by a second-priority lien on all of the domestic assets of the Company and its domestic subsidiaries that secure the Company’s reimbursement obligations under the Synthetic LC Facility on a first-priority basis (as described below); provided that such assets do not include any capital stock, notes, instruments, other equity interests of any of the Company’s subsidiaries, accounts receivable, and certain other excluded collateral as provided in the Indenture. The Senior Secured Notes are jointly and severally guaranteed on a senior secured second-lien basis by substantially all of the Company’s existing and future domestic subsidiaries. The Senior Secured Notes are not guaranteed by the Company’s foreign subsidiaries.

Revolving Facility and Synthetic LC Facility or the offer to the repurchase of all or part of the then outstanding Senior Secured Notes. “Excess Cash Flow” is defined in the Indenture as consolidated EBITDA less interest expense, all taxes paid or accrued in the period, capital expenditures made in cash during the period, and all cash spent on environmental monitoring, remediation or relating to environmental liabilities of the Company.

The $6.0 million cost associated with the issuance of the Senior Secured Notes was recorded as a component of deferred financing costs and is being amortized to interest expense over the life of the Senior Secured Notes.

Revolving Facility. Both the Revolving Facility and the Synthetic LC Facility were established under a Loan and Security Agreement dated June 30, 2004 (the “Credit Agreement”) among the Company, Fleet Capital Corporation as agent for the Revolving Lenders thereunder, Credit Suisse First Boston as agent for the letter of credit facility lenders (the “LC Facility Lenders”) thereunder, and certain other parties. The Revolving Facility allows the Company to borrow up to $30.0 million in cash, based upon a formula of eligible accounts receivable. This total is separated into two lines of credit, namely a line for the Company and its U.S. subsidiaries equal to $24.7 million and a line for the Company’s Canadian subsidiaries of $5.3 million. The Revolving Facility also allows the Company to have issued up to $10.0 million of letters of credit, with the outstanding amount of such letters of credit reducing the maximum amount of borrowings permitted under the Revolving Facility. At September 30, 2004, the Company had $0.0 million of borrowings and $1.2 million of letters of credit outstanding under the Revolving Facility, and the Company had approximately $28.8 million available to borrow. Amounts outstanding under the Revolving Facility bear interest at an annual rate of either the U.S. or Canadian prime rate or the Eurodollar rate (depending on the currency of the underlying loan) plus 1.50%. The Credit Agreement requires the Company to pay an unused line fee of 0.125% per annum on the unused portion of the Revolving Facility. The Revolving Facility matures on June 30, 2009.

The Revolving Facility is secured by a first security interest in accounts receivable and a second security interest in substantially all other assets. The Revolving Facility prohibits the payment of dividends on the Company’s common stock but allows the payment of dividends on the Company’s Series B Preferred Stock.

Under the Credit Agreement, the Company is required to maintain a maximum Leverage Ratio (as defined below) of no more than 3.00 to 1.0, 2.80 to 1.0 and 2.55 to 1.0 for the four-quarter periods ending September 30, 2004, December 31, 2004 and March 31, 2005, respectively. The maximum Leverage Ratio is then reduced to no more than 2.50 to 1.0 for the four-quarter period ending June 30, 2005, and then, in approximately equal increments, to no more than 2.30 to 1.0 for the four-quarter period ending December 31, 2008, and to no more than 2.25 to 1.0 for each succeeding quarter. The Leverage Ratio is defined as the ratio of the consolidated indebtedness of the Company to its consolidated EBITDA achieved for the latest four-quarter period. For the four-quarter period ended September 30, 2004, the Leverage Ratio was 2.09 to 1.0, which was within covenant.

The Company is also required under the Credit Agreement to maintain a minimum Interest Coverage Ratio (as defined below) of not less than 2.25 to 1.0, 2.40 to 1.0 and 2.65 to 1.0 for the four-quarter periods ending September 30, 2004, December 31, 2004 and March 31, 2005, respectively. The minimum Interest Coverage Ratio is then increased to not less than 2.70 to 1.0 for the four-quarter period ending June 30, 2005, and then, in approximately equal increments, to not less than 2.85 to 1.0 for the four-quarter period ending December 31, 2006 through December 31, 2008, and not less than 3.00 to 1.0 for each succeeding four-quarter period. The Interest Coverage Ratio is defined as the ratio of the Company’s consolidated EBITDA to its consolidated interest expense. For the four-quarter period ended September 30, 2004, the Interest Coverage Ratio was 2.98 to 1.0, which was within covenant.

The Company is also required to maintain a fixed charge coverage ratio of not less than 1.0 to 1.0 for each four-quarter period, commencing with the quarter ending December 31, 2004. The Company must also achieve at least $15.0 million in consolidated EBITDA for the quarter ended September 30, 2004. For the quarter ended September 30, 2004, EBITDA was $19.6 million which was within covenant.

The $0.3 million cost associated with the issuance of the Revolving Facility was recorded as a component of deferred financing costs and is being amortized to interest expense over the life of the Revolving Facility.

all of the assets of the Company and its domestic subsidiaries. The Company has no right, title or interest in the Credit-Linked Account established under the Credit Agreement for purposes of the Synthetic LC Facility. The Company is required to pay (i) a quarterly participation fee at the annual rate of 5.35% on the average daily balance in the Credit-Linked Account and (ii) a quarterly fronting fee at the annual rate of 0.30% of the average daily aggregate amount of letters of credit outstanding under the Synthetic LC Facility. At September 30, 2004, letters of credit outstanding under the Synthetic LC facility were $89.3 million. The term of the Synthetic LC Facility will expire on June 30, 2009.

The $3.3 million cost associated with the issuance of the Synthetic LC Facility was recorded as a component of deferred financing costs and is being amortized to interest expense over the life of the Synthetic LC Facility.

EBITDA. In addition to disclosing financial results that are determined in accordance with generally accepted accounting principles (“GAAP”), the Company uses the non-GAAP measure EBITDA. As described above, the principal financial covenants to which the Company is subject under the Credit Agreement are based upon the level of EBITDA (as defined in the Credit Agreement) achieved by the Company in specified periods. Furthermore, 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 Company’s ability to fund capital expenditures and service debt. The Company also uses EBITDA to award management incentive bonuses based on the level of EBITDA attained.

EBITDA should not be considered an alternative to net income or loss or other measures calculated in accordance with accounting principles generally accepted in the United States 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.

Because of certain non-recurring adjustments to net income (loss) which occurred during the six months ended March 31, 2004, the Credit Agreement defines EBITDA for the fiscal quarters ended December 31, 2003 and March 31, 2004, as being in the agreed amounts of $16.0 million and $12.1 million, respectively. EBITDA under the Credit Agreement for the six-month period ended September 30, 2004 is calculated as follows (in thousands):

	Six Months Ended September 30, 2004

Net loss	$	(7,686	)

(7) Legal Proceedings and Contingencies

As of the filing date of this report, the following discussions update the material changes to the “Legal Proceedings” described in Note 9 to the Company’s financial statements as of December 31, 2003 included in the Annual Report on Form 10-K as filed with the SEC on March 15, 2004 and in Note 7 to the Company’s financial statements as of June 30, 2004 included in the Company’s Quarterly Report on Form 10-Q as filed with the SEC on August 6, 2004.

Legal Proceedings Assumed In Connection with Acquisition of CSD Assets

The CSD assets included a former hazardous waste incinerator and landfill in Baton Rouge, Louisiana (“BR Facility”) currently undergoing remediation pursuant to an order issued by the Louisiana Department of Environmental Quality. In December 2003, the Company received an information request from the United States Environmental Protection Agency (“EPA”) pursuant to the Comprehensive Environmental Response, Compensation and Liability Act (“Superfund Act”) concerning the Devil’s Swamp Lake Site (“Devil’s Swamp”) in East Baton Rouge Parish, Louisiana, and the BR Facility received and responded to a supplemental information request from EPA on October 15, 2004. On March 8, 2004, the EPA proposed to list Devil’s Swamp on the National Priorities List (“NPL”) for further investigations and possible remediation. Devil’s Swamp includes a lake located downstream of an outfall ditch where wastewaters and storm waters have been discharged from the BR Facility, as well as extensive adjacent swamplands. Contaminants of concern cited by the EPA as a basis for listing the site on the NPL include substances of the kind found in wastewaters discharged from the BR Facility in past operations. While the Company’s ongoing corrective actions at the BR Facility may be sufficient to address the EPA’s concerns, there can be no guarantee that, if the site is ultimately listed as a Superfund site on the NPL, additional action will not be required and that the Company will not incur material costs. The Company cannot now estimate its potential liability relating to Devil’s Swamp; accordingly, the Company has accrued no liability relating to Devil’s Swamp except for the amount already accrued for the ongoing corrective actions and certain legal costs associated with responding to the EPA information requests and further investigation of the matter.

Canadian Provincial Enforcement Action

London, Ontario Facility. Clean Harbors Environmental Services Inc., and one of the Company’s Canadian subsidiaries, Clean Harbors Canada, Inc., have received a summons alleging a number of regulatory offenses under the Ontario Occupational Health and Safety Act as a result of a fire in October 2003 at a Clean Harbors Canada, Inc., waste transfer facility in London, Ontario. A worker at the facility received serious injuries as a result of the fire.

The initial appearance on this matter is set for November 22, 2004. The Company will determine its position with respect to the charged offenses following receipt and review of disclosure on the case by the Provincial authorities. The Company has not accrued any liability associated with this matter because any potential liability is not now estimable.

Contingencies

Federal Securities Class Action Litigation. On November 18, 2003, an individual plaintiff who purchased 1,700 shares of the Company’s common stock filed a purported class action suit in the United States District Court for the District of Massachusetts (the “District Court”) against the Company and a current and former officer of the Company. The plaintiff alleges violation of the Securities Exchange Act of 1934 and regulations promulgated thereunder by the SEC, and seeks certification of a class that would consist of all purchasers of the Company’s stock between November 19, 2002 and August 14, 2003. Principally, the complaint alleges that in connection with certain public announcements the defendants failed to disclose adverse information with respect to the impact of the acquisition of the CSD assets on the Company and that certain financial projections, particularly the guidance issued with respect to anticipated EBITDA for 2003, were overstated and made without reasonable basis. Subsequently, three additional plaintiffs who purchased 300, 16,500 and 1,500 shares of the Company’s common stock, respectively, filed complaints in the same court containing essentially the same allegations and seeking the same class certification. In January 2004, several plaintiffs within the putative class filed, through their attorneys, competing motions seeking to be named lead plaintiff, seeking the right to select lead counsel and seeking consolidation of the four suits. On October 26, 2004, the District Court issued an order giving the plaintiffs until November 30, 2004 to file an amended consolidated complaint and the Company until December 31, 2004 to file a motion to dismiss the complaint, and setting February 15, 2005 as the date for a hearing on such motion.

The Company believes that at all times during the purported class period the Company and the two officers conducted themselves in compliance with relevant securities laws and that the guidance as to anticipated EBITDA and other forward-looking statements contained in the Company’s public announcements are protected by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. The Company intends to vigorously defend itself against the plaintiffs’ allegations. However, this litigation is in its very preliminary stages, and the Company is therefore unable to give an assessment of any potential impact on the Company.

Remaining capacity at September 30, 2004	28,461

Commencing January 1, 2004, asset retirement obligations incurred are being discounted at the credit-adjusted risk-free rate of 12.5% and inflated at a rate of 1.2%.

(9) Redeemable Series C Preferred Stock

As described in the Annual Report on Form 10-K for the year ended December 31, 2003, the Company previously had outstanding the Series C Convertible Preferred Stock, $0.01 par value (“Series C Preferred Stock”). The Series C Preferred Stock was entitled to receive dividends at an annual rate of 6.0% (such dividends were paid in cash through March 2003 and thereafter accrued and compounded through the redemption date). The Company issued the Series C Preferred Stock for $25.0 million on September 10, 2002, and incurred $2.9 million of issuance costs. The Company determined that the Series C Preferred Stock should be recorded on the Company’s financial statements as though the Series C Preferred Stock consisted of two components, namely (i) non-convertible redeemable preferred stock (the “Host Contract”) with a 6.0% annual dividend, and (ii) an embedded derivative (the “Embedded Derivative”) which reflected 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 Series C Preferred Stock reported on the Company’s consolidated balance sheet consisted only of the value of the Host Contract (less the issuance costs) plus the amount of accretion in the value of the Host Contract which had been recorded through the balance sheet date with regard to the discount which was originally recorded for the Host Contract, plus the amount of accretion for issuance costs and accrued dividends. Such discount and issuance costs were being accreted over the life of the Series C Preferred Stock, with such accretion being recorded as a reduction in Additional Paid-in-Capital. During the period from January 1 through June 30, 2004, the amount of that accretion was $0.7 million. For the quarter ended September 30, 2004, no accretion was recorded because the Company redeemed the Series C Preferred Stock on June 30, 2004. During the period from January 1 through September 30, 2003, the amount of that accretion was $0.7 million. The Company recorded in Other Long-term Liabilities the fair value of the Embedded Derivative and periodically marked that value to market.

On June 30, 2004, the Company redeemed the Series C Preferred Stock for $25.0 million in cash and paid accrued dividends of $2.0 million. The difference between the $25.0 million paid and the carrying amount of the Series C Preferred Stock of $17.2 million on June 30, 2004 was charged to additional paid-in capital. In addition, the Company issued warrants to purchase 2.8 million shares of the Company’s common stock, and the Company paid $0.4 million of cash in lieu of warrants for certain other conversion rights of the holders of the Series C Preferred Stock. The warrants issued are exercisable at $8.00 per common share and expire on September 10, 2009. The Company settled the $11.2 million Embedded Derivative liability through the issuance of the 2.8 million warrants (which the Company valued using the Black-Scholes option pricing model at $9.2 million) together with the $0.4 million of cash that was paid in lieu of warrants, which resulted in a gain on the settlement of the Embedded Derivative of $1.6 million. The gain on the settlement of the Embedded Derivative was recorded as a reduction to refinancing-related expenses. The value of the warrants issued of $9.2 million was credited to additional paid-in capital.

As of September 30, 2003, the Embedded Derivative was determined to have no value based on the Black-Scholes valuation model and the Company recorded $8.7 million and $9.2 million of other income for the three and nine-month periods ended September 30, 2003, respectively, to reflect such adjustment. Because of the redemption of the Series C Preferred Stock on June 30, 2004 described in the preceding paragraph, the Company will not be required to make mark-to-market adjustments to the Company’s reported income (loss) associated with the Embedded Derivative for any period subsequent to June 30, 2004. As of June 30, 2004, the market value of the Embedded Derivative was determined to $11.2 million and the Company recorded other expense of $1.6 million through June 30, 2004 to reflect such adjustment.

(10) Loss on Refinancing

As further discussed in Notes 4, 6, and 9, the Company previously had outstanding a $100.0 million three-year revolving credit facility (the “Revolving Credit Facility”), $115.0 million of three-year non-amortizing term loans (the “Senior Loans”), $40.0 million of five-year non-amortizing subordinated loans (the “Subordinated Loans”), Series C Convertible Preferred Stock, $0.01 par value (the “Series C Preferred Stock”) and the related embedded derivative (the “Embedded Derivative”) which reflected 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. On June 30, 2004, the Company repaid the Revolving Credit Facility, the Senior Loans and the Subordinated Loans, redeemed the Series C Convertible Preferred Stock and settled the related Embedded Derivative liability. The Company recorded refinancing expenses, net of $7.1 million during the three-month period ended June 30, 2004. Such expenses consisted of a write-off of deferred financing costs of $5.3 million, prepayment penalties of $3.1 million, and other expenses of $0.3 million. These expenses were partially offset by the gain on the settlement of the Embedded Derivative of $1.6 million.

(11) 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-month periods ended September 30, 2004, 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. The provision for income taxes for the three- and nine-month periods ended September 30, 2003 and 2004 relate primarily to the Company’s Canadian subsidiaries.

(12) Earnings (Loss) Per Share

The following is a reconciliation of basic and diluted loss per share computations (in thousands except for per share amounts) for the three- and nine-month periods ended September 30, 2004 and 2003:

Because the effects would be anti-dilutive for the periods presented, the above computations of diluted income (loss) per share excludes the following: (i) for the three- and nine month periods ended September 30, 2004 the effects of 0.8 and 1.7 million options outstanding, respectively, (ii) for both the three- and nine- month periods ended September 30, 2004 the effects of the conversion of the Series B Preferred Stock into 0.3 million shares of common stock, and (iii) for the nine-month period ended September 30, 2004 the effect of 2.8 million warrants outstanding.

Because the effects would be anti-dilutive for the periods presented, the above computations of diluted income (loss) per share excludes the following: (i) for the three- and nine month periods ended September 30, 2003 the effects of 1.8 million options outstanding, (ii) for the nine- month periods ended September 30, 2004 the effects of the conversion of the Series B Preferred Stock into 0.3 million shares of common stock, and (iii) for the nine-month period ended September 30, 2003 the effect of 2.4 million warrants outstanding.

(13) Restructuring

For the year ended December 31, 2002, the Company recorded a restructuring charge of $0.8 million related to the acquisition of the assets of the CSD. The restructuring charge consisted of $0.3 million for severance for individuals that were employees of the Company prior to the acquisition, and $0.5 million 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 December 31, 2003 through September 30, 2004 (in thousands):

	Locations

(14) 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.

The following table presents information used by management by reported segment. Revenues from Technical and Site Services consist principally of external revenue from customers. Transactions between the segments are accounted for at the Company’s estimate of fair value based on similar transactions with outside customers. Corporate Items consist of revenues for miscellaneous services that are not part of a reportable segment. The Company does not consider interest expense, income taxes, depreciation, amortization, accretion of environmental liabilities, restructuring or other acquisition costs when reviewing results of operating segments. Certain reclassifications have been made in the prior period to conform to the presentation for the three and nine-month periods ended September 30, 2004 (in thousands):

(15) Guarantor and Non-Guarantor Subsidiaries

As further described in Note 6, the Senior Secured Notes were issued by the parent company, Clean Harbors, Inc., and guaranteed by all of the parent’s material subsidiaries organized in the United States. The Notes are not guaranteed by the Company’s Canadian and Mexican subsidiaries. The following presents condensed consolidating financial statements for the parent company, the guarantor subsidiaries and the non-guarantor subsidiaries, respectively.

In addition, as part of the refinancing of the Company’s debt, one of the parent’s Canadian subsidiaries made a $91.7 million (U.S.) investment in the preferred stock of one of the parent’s domestic subsidiaries and issued, in partial payment for such investment, a promissory note for $89.4 million (U.S.) payable to one of the parent’s domestic subsidiaries. The dividend rate on such preferred stock is 11.125% per annum and the interest rate on such promissory note is 11.0% per annum. The effect of this transaction is to increase stockholders’ equity of a U.S. guarantor subsidiary, to increase interest income of a U.S. guarantor subsidiary, to increase debt of a foreign non-guarantor subsidiary, and to increase interest expense of a foreign non-guarantor subsidiary.

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 will continue to result in significant cost savings by allowing the Company to treat and dispose of hazardous waste internally that the Company previously paid third parties for and to eliminate redundant selling, general and administrative expenses and inefficient transportation costs.

The Company believes that significant synergies can be achieved by further integrating the former CSD operations into its business. Since the effective date of the acquisition, the Company has reduced and plans to continue 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 also has eliminated and plans to continue to eliminate duplicate costs relating to overlapping operations on a geographic basis. Although much of the integration of operations and reduction of the combined entities’ overlapping costs has been completed, this process is still ongoing.

In addition, as part of the acquisition, the Company assumed certain environmental liabilities valued at $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 in greater amounts than now anticipated.

As further discussed in Item 4, “Controls and Procedures,” Safety-Kleen had publicly disclosed prior to the Company's acquisition of the CSD assets in 2002 that the CSD 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 U.S. operations of the former CSD into the Company’s business and financial reporting systems effective as of the acquisition date. Due to the acquisition of the CSD, the Company continues to experience deficiencies in certain of its internal controls. The Company has made significant progress in resolving the internal control weaknesses caused by the integration of the CSD into its systems, and the Company has on-going efforts to strengthen its internal controls.

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 for the year ended December 31, 2003 and Item 1, “Financial Statements” in this report.

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

The Company defines EBITDA as 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.

EBITDA should not be considered an alternative to net income or loss or other measurements under accounting principles generally accepted in the United States 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.

Segment data

Performance of the Company’s segments is evaluated on several factors of which the primary financial measure is EBITDA. 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-month periods ended September 30, 2004 and 2003. 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 20, “Segment Reporting” of the Annual Report on Form 10-K for the year ended December 31, 2003 and Item 1, “Financial Statements” and in particular Note 14, “Segment Reporting” in this report.

Three months ended September 30, 2004 versus the three months ended September 30, 2003

Revenues

Total revenues for the three months ended September 30, 2004 increased $11.6 million to $162.7 million from $151.1 million for the comparative period in 2003. Technical Services revenues for the three months ended September 30, 2004 increased $5.6 million to $111.9 million from $106.3 million for the comparative period in 2003. Site Services revenues for the three months ended September 30, 2004 increased $5.9 million to $50.5 million from $44.6 million for the comparative period in 2003. Increases in Technical Services revenues resulted from a stronger economy and improved disposal volumes in the Company’s landfill and incineration assets. Site Services revenue improvements resulted largely from several large industrial services projects as well as continued improvements in start up markets in the West and in Canada. Improvements were partially offset by weakness in the Mid-Atlantic area. There were no major events in the third quarter of 2004 or 2003.

There are many factors which have impacted, and continue to impact, the Company’s revenues. These factors include: 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, 2004 increased $8.1 million to $116.8 million compared to $108.7 million for the comparable period in 2003. Technical Services cost of revenue increased $3.2 million to $74.9 million from $71.7 million for the comparable period in 2003. Site Services cost of revenue increased $6.6 million to $41.0 million from

$34.4 million for the comparable period in 2003. The increase in cost of revenues for Technical Services was largely a result of higher volumes, increases in energy costs, and greater usage of outside transportation vendors on certain facility projects. The increase in cost of revenues for Site Services was attributed to higher volumes and included $1.3 million of expenses to third party transporters relating to several lower margin industrial service projects. The third quarter of 2003 included final negotiation of holdback provisions related to a major emergency response. Reduced costs of revenue related to this expense resolution were approximately $0.3 million. As a percentage of revenues, combined cost of revenues in the third quarter of 2004 decreased 0.1% to 71.8% from 71.9% for comparable period in 2003.

The Company believes that its ability to manage operating costs is an important factor in its ability to remain price competitive. The Company continues to upgrade the quality and efficiency of its waste treatment services through the development of new technology, continued modifications and upgrades at its facilities, and implementation of strategic sourcing initiatives. The Company plans to continue to focus on achieving cost savings relating to purchased goods and services through the strategic sourcing initiative. No assurance can be given that the Company’s efforts to manage future operating expenses will be successful.

Selling, General and Administrative Expenses

Total selling, general and administrative expenses for the three months ended September 30, 2004 increased $0.4 million to $26.2 million from $25.8 million for the comparable period in 2003. Technical Services selling, general and administrative expenses for the three months ended September 30, 2004 decreased $0.4 million to $11.9 million from $12.3 million for the comparable period in 2003 due to reduced headcount expenses. Site Services expenses increased by $0.2 million due to increased headcount costs related to opening of new offices. Corporate selling, general and administrative expenses increased by $0.6 million for three months ended September 30, 2004 compared to the same period of the prior year. The increase was due to bonuses relating to improved operating performance and higher professional fees associated with Sarbanes-Oxley Section 404. These increases in expenses were partially offset by savings from reduced headcount.

Accretion of Environmental Liabilities

Accretion of environmental liabilities for the three-month periods ended September 30, 2004 and 2003 was similar at $2.5 million and $2.7 million, respectively.

Depreciation and Amortization

Depreciation and amortization expense of $5.8 million for the three months ended September 30, 2004 decreased from $6.8 million for the comparable period in 2003 due to changes in estimates in landfill lives and changes in estimates in useful lives of certain assets.

Other Income (Expense)

For the quarter ended September 30, 2004, the Company recorded a loss on the sale of fixed assets to other expense of $0.1 million.

As more fully described in Note 9 to the financial statements in this report, the Company issued Series C Preferred Stock for $25.0 million in September 2002. The Series C Preferred Stock was recorded on the Company’s financial statements as though it consisted of two components, namely (i) non-convertible redeemable preferred stock with a 6.0% annual dividend, and (ii) an embedded derivative (the “Embedded Derivative”) which reflected the right of the holders of the Series C Preferred Stock to convert the Series C Preferred Stock into the Company’s common stock. On June 30, 2004, the Company redeemed the Series C Preferred Stock and settled the Embedded Derivative liability. Just prior to the settlement, 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 the volatility of the stock price. The strike price of the Embedded Derivative was $8.00. The settlement of the Embedded Derivative liability on June 30, 2004 will result in no additional other income (expense) being recorded in future periods related to the Embedded Derivative. For the quarter ended September 30, 2003, the Company recorded other income related to the Embedded Derivative of $8.7 million.

Interest (Expense), Net

Interest expense, net of interest income, for the three months ended September 30, 2004 decreased $0.5 million to $5.5 million from $6.0 million for the comparable period in 2003. The decrease in interest expense was due primarily to $0.6 million of capitalized interest relating to a capital project to comply with air emission standards at the Company’s Deer Park incineration

facility, which was partially offset by reduced interest income associated with the Company’s restricted cash balances for the three months ended September 30, 2004 as compared to the same period in 2003.

Income Taxes

Income tax expense for the three months ended September 30, 2004 decreased $0 .6 million to $ 1.1 million from $1.7 million for the comparable period in 2003. Income tax expense for the three months ended September 30, 2004 consists primarily of Canadian taxes of $1.0 million including withholding taxes of $0.2 million and Federal and state income tax expense of $0.1 million. Income tax expense for the three month period ended September 30, 2003 consists primarily of Canadian taxes of $1.6 million and Federal and state income tax expense of $0.1 million.

EBITDA Contribution

The EBITDA contribution for the three months ended September 30, 2004 increased $3.0 million to $19.6 million from $16.6 million for the comparable period in 2003. The increase from Technical Services was $2.8 million. For Site Services, EBITDA contribution decreased by $0.9 million. Corporate Items resulted in an increase of $1.1 million. The combined EBITDA contribution was comprised of revenues of $162.7 million and $151.1 million, net of cost of revenues of $116.8 million and $108.7 million and selling, general and administrative expenses of $26.2 million and $25.8 million for the three months ended September 30, 2004 and 2003, respectively.

Nine months ended September 30, 2004 versus the nine months ended September 30, 2003

Revenues

Total revenues for the nine months ended September 30, 2004 increased $1.6 million to $467.0 million from $465.4 million for the comparative period in 2003. Technical Services revenues for the nine months ended September 30, 2004 increased $9.0 million to $327.9 million from $318.9 million for the comparative period in 2003. The increases in Technical Services revenue resulted from an improving economy, volume increases realized in the Company’s landfill and incineration assets. Site Services revenues for the nine months ended September 30, 2004 decreased $7.0 million to $138.6 million from $145.6 million for the comparative period in 2003. Site Services performed one large emergency response job during the nine months ended September 30, 2003, which accounted for 12.2% of its revenues for that period. There was no comparable job in the nine months ended September 30, 2004. Excluding this one large job, revenue increased $10.8 million, or 8.5%, for the nine months ended September 30, 2004 compared to the nine months ended September 30, 2003 as a result of growth initiatives in Gulf and Western United States, increased volumes of large industrial services projects, improvements in our oil and PCB recycling divisions and an improving economy. These improvements are partially offset by weakness in the Mid-Atlantic markets. Changes in foreign exchange rates positively impacted consolidated sales by approximately $4.1 million.

Cost of Revenues

Total cost of revenues for the nine months ended September 30, 2004 decreased $7.0 million to $340.1 million compared to $347.1 million for the comparable period in 2003. Technical Services cost of revenue decreased $1.2 million to $221.3 million from $222.6 million for the comparable period in 2003. Site Services cost of revenue decreased $0.3 million to $113.0 million from $113.3 million for the comparable period in 2003. Corporate cost of revenues decreased $5.4 million to $5.8 million from $11.2 million for the comparable period in 2003. The decrease in cost of revenues for Technical Services was due to lower labor costs in our processing facilities, partially offset by higher fuel costs. The decrease in cost of revenues for Site Services was attributable to the lack of costs related to a major emergency response in comparison to the same period in 2003. The decrease in cost of revenues for Corporate departments was due to reduced costs at our discontinued waste handling facilities. Corporate cost of revenues for 2003 included a one-time charge of $1.7 million related to health care. As a percentage of revenues, combined cost of revenues in 2004 decreased 1.8% to 72.8% from 74.6% for the comparable period in 2003. This improvement resulted primarily because of improvements in outside disposal costs due to the Company’s internalization of waste initiatives, and lower headcount expenses.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the nine months ended September 30, 2004 decreased $7.2 million to $76.0 million from $83.2 million for the comparable period in 2003. Technical Services selling, general and administrative expenses for the nine months ended September 30, 2004 decreased $2.5 million to $35.0 million from $37.5 million for the comparable period in 2003 primarily due to reduced headcount. Site Services selling, general and administrative expenses were flat at $13.0 million for the nine months ended September 30, 2004 compared to the same period of the prior year. Partially offsetting the decreases in headcount for Site Services were increased costs related to the opening of additional locations. Corporate Items selling, general and administrative expenses for the nine months ended September 30, 2004 decreased $4.6 million to $28.1

million from $32.7 million for the comparable period in 2003. The decrease was due to reduced currency exchange expense, decreases in headcount, decreased professional fees, and improved controls over expenses. These expense reductions were offset by higher bonus accruals and expenses associated with the refinancing of the Company’s capital structure in June 2004 as well as expenses related to Sarbanes-Oxley Section 404 compliance.

Accretion of Environmental Liabilities

Accretion of environmental liabilities for the nine-month periods ended September 30, 2004 and 2003 was similar at $7.8 million and $8.3 million, respectively.

Depreciation and Amortization

Depreciation and amortization expense of $17.5 million for the nine months ended September 30, 2004 decreased from $19.9 million for the comparable period in 2003 due to changes in estimates in landfill lives and changes in estimates in useful lives of certain assets.

Other Income (Expense)

As more fully described in Note 9 to the financial statements in this report, the Company issued Series C Preferred Stock for $25.0 million in September 2002. The Series C Preferred Stock was recorded on the Company’s financial statements as though it consisted of two components, namely (i) non-convertible redeemable preferred stock with a 6.0% annual dividend, and (ii) an embedded derivative (the “Embedded Derivative”) which reflected the right of the holders of the Series C Preferred Stock to convert the Series C Preferred Stock into the Company’s common stock. On June 30, 2004, the Company redeemed the Series C Preferred Stock and settled the Embedded Derivative liability. Just prior to the settlement, 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 the volatility of the stock price. The strike price of the Embedded Derivative was $8.00. The settlement of the Embedded Derivative liability on June 30, 2004 will result in no additional other income (expense) being recorded in future periods related to the Embedded Derivative. For the nine month period ended September 30, 2004, the Company recorded other expense related to the Embedded Derivative of $1.6 million primarily because of the market price increase of the Company’s common stock that occurred during that period. For the nine month period ended September 30, 2003, the Company recorded a gain on the Embedded Derivative of $9.2 million. Partially offsetting the expense on the Embedded Derivative during the nine months ended September 30, 2004 and 2003 was respectively a net gain and net loss on the disposal of fixed assets of $0.4 million and $(0.3) million.

Loss on Refinancing

As further discussed in Notes 4, 6, and 9 to the financial statements included in this report, the Company previously had outstanding a $100.0 million three-year revolving credit facility (the “Revolving Credit Facility”), $115.0 million of three-year non-amortizing term loans (the “Senior Loans”), $40.0 million of five-year non-amortizing subordinated loans (the “Subordinated Loans”), Series C Convertible Preferred Stock, $0.01 par value (the “Series C Preferred Stock”) and the related embedded derivative (the “Embedded Derivative”) which reflected 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. On June 30, 2004, the Company repaid the Revolving Credit Facility, the Senior Loans and the Subordinated Loans, redeemed the Series C Convertible Preferred Stock and settled the related Embedded Derivative liability. The Company recorded refinancing expenses, net of $7.1 million during the three-month period ended June 30, 2004. Such expenses consisted of write-off of deferred financing costs of $5.3 million, prepayment penalties of $3.1 million and other expenses of $0.3 million. These expenses were partially offset by the gain on the settlement of the Embedded Derivative of $1.6 million.

Interest (Expense), Net

Interest expense, net of interest income, for the nine months ended September 30, 2004 decreased $1.2 million to $16.3 million from $17.5 million for the comparable period in 2003. The decrease in interest expense was due to $1.9 million of capitalized interest relating to a capital project to comply with air emission standards at the Company’s Deer Park incineration facility which was partially offset by reduced interest income on the company’s restricted cash balances and a slight increase in interest expense on capital leases, for the nine months ended September 30, 2004 as compared to the same period in 2003.

Income Taxes

Income tax expense for the nine months ended September 30, 2004 increased $0.7 million to $4.7 million from $4.0 million for the comparable period in 2003. Income tax expense for the nine months ended September 30, 2004 consists primarily of Canadian taxes of $4.5 million including

withholding taxes of $0.2 million and Federal and state income tax expense of $0.2. Income tax expense for the nine month period ended September 30, 2003 consists primarily of Canadian taxes of $3.8 million and Federal and state income tax expense of $0.2 million.

EBITDA Contribution

The EBITDA contribution for the nine months ended September 30, 2004 increased $15.8 million to $50.9 million from $35.1 million for the comparable period in 2003. The increase from Technical Services was $12.8 million. For Site Services, EBITDA decreased $6.6 million with an increase in Corporate Items of $9.6. The combined EBITDA contribution was comprised of revenues of $467.0 million and $465.4 million, net of cost of revenues of $340.1 million and $347.1 million and selling, general and administrative expenses of $76.0 million and $83.2 million for the nine months ended September 30, 2004 and 2003, respectively.

Liquidity and Capital Resources

Cash and Cash Equivalents

The Company’s believes that its primary source of liquidity is from cash flows from operations, existing cash, funds available to borrow under the Revolving Facility and anticipated proceeds from assets held for sale. As of September 30, 2004, cash and cash equivalents was approximately $24.8 million, funds available to borrow under the Revolving Facility were $28.8 million and properties held for sale was $12.3 million. As further discussed below under “Financing Arrangements”, on June 30, 2004, the Company refinanced its outstanding debt and redeemed its then outstanding Series C Preferred Stock. The refinancing resulted in the Company having both more cash on hand and funds available to borrow under its Revolving 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. In addition, the Company projects that it will continue to meet its debt covenant requirements for the foreseeable future. As part of the CSD acquisition, the Company assumed environmental liabilities of the CSD valued at $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, 2004

For the nine months ended September 30, 2004, the Company generated approximately $25.0 million of cash from operating activities. Non-cash expenses recorded for the nine months ended September 30, 2004 totaled $35.7 million. These non-cash expenses consisted primarily of $17.5 million for depreciation and amortization, $7.8 million for the accretion of environmental liabilities, refinancing expenses of $7.1 million, $1.9 million for amortization of deferred financing costs and a loss on the embedded derivative of $1.6 million. Other sources of cash totaled $10.4 million which primarily consisted of an increase in other accrued expenses of $4.7 million, an increase in the income taxes payable of $3.5 million, an increase in deferred revenue of $0.9 million due to higher levels of waste inventory on hand at September 30, 2004 as compared to December 31, 2003, and an increase in accrued disposal costs of $0.9 million due to higher levels internally generated waste to be disposed of at September 30, 2004 as compared to December 31, 2003. These sources of cash were partially offset by other uses of cash that totaled $16.3 million consisting primarily of a decrease in environmental liabilities of $9.1 million relating primarily to expenditures for environmental liabilities, an increase in accounts receivable of $3.4 due to a higher level of revenues in the quarter ended September 2004 compared with the quarter ended December 2003, an increase in prepaid expenses of $2.1 million and an increase of $1.2 million in other assets.

For the nine months ended September 30, 2004, the Company generated $69.3 million of cash from investing activities. This consisted of proceeds from the sale of restricted investments of $92.8 million that resulted primarily from the Company no longer being required to post cash collateral for financial assurance for closure and post closure care of its facilities and proceeds from the sale of fixed assets of $0.6 million. Partially offsetting these sources of cash were uses of cash to acquire property, plant and equipment and permits of $19.7 million and to post cash collateral of $4.4 million.

For the nine months ended September 30, 2004, the Company used $76.0 million of cash in its financing activities. Cash from financing activities consisted primarily of the issuance of Senior Secured Notes (net of unamortized issue discount) of $148.0 million. This was offset by repayments of Senior Loans and Subordinated Loans of $107.2 million and $40.0 million, respectively, repayment of the former Revolving Credit Facility of $35.2 million, and redemption of the Series C Preferred Stock

of $25.0 million. Additional offsets consisted primarily of deferred financing costs incurred of $10.3 million, debt extinguishment payments of $3.4 million, dividend payments of $2.1 million, and payments on capital leases of $1.1 million.

The Company used the cash generated from investing activities of $69.3 million together with the $25.0 million of cash generated from operations and $0.2 million generated from the favorable foreign exchange impact on cash to fund the financing activities of $76.0 million previously discussed, and increase the amount of cash on hand by $18.5 million.

Cash Flows for the nine months ended September 30, 2003

For the nine months ended September 30, 2003, the Company generated approximately $29.9 million of cash from operating activities. Non-cash expenses recorded for the nine months ended September 30, 2003 totaled $23.7 million. These adjustments consisted primarily of non-cash expenses of $19.9 million for depreciation and amortization, $8.3 million for the accretion of environmental liabilities, $1.4 million of allowance for doubtful accounts and $1.8 million for amortization of deferred financing costs. Other sources of cash for the nine months ended September 30, 2003 totaled $28.6 million which primarily consisted of a decrease in accounts receivable of $20.6 million, a decrease in prepaid expenses of $3.5 million, a decrease in deferred costs of $0.8 million, a decrease in unbilled accounts receivable of $3.1 million, and an increase in other accrued expenses of $0.4 million. Other uses of cash totaled $15.8 million and consisted primarily of a decrease in deferred revenue of $5.5 million, which was due primarily to improvements realized by the integration of the CSD into the Company’s operations, a decrease in environmental liabilities of $6.0 million, a decrease in accounts payable of $2.3 million, a decrease in income taxes payable of $0.5 million and a decrease 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. This consisted of additions to property, plant and equipment and permits of $25.8 million and restricted investments purchased of $34.2 million to support the letters of credit issued relating to financial assurance for closure and post-closure obligations. These uses were partially offset by a Global Settlement Payment received from Safety-Kleen Corp. for the purchase price of the Chemical Services Division of $8.0 million, proceeds from the sale of restricted investments of $5.8 million and proceeds from the sale of fixed assets of $1.6 million.

For the nine months ended September 30, 2003, the Company raised $6.3 million of cash from financing activities. Cash from financing activities consisted primarily of net borrowings of $17.8 million on the Revolving Credit Facility, proceeds from the exercise of stock options of $0.4 million and proceeds from the employee stock purchase plan of $0.4 million. Partially offsetting this were repayments of $7.5 million on Senior Loans and dividend payments of $1.0 million, a decrease in uncashed checks of $1.8 million, deferred financing costs incurred of $1.5 million, and payments on capital leases of $0.5 million..

The Company used the cash generated from financing activities of $6.3 million together with the $29.9 million of cash generated from operations primarily to fund the investing activities of $44.5 million previously discussed, and decrease the amount of cash on hand by $8.3 million.

Financing Arrangements

The principal terms of the Senior Secured Notes, the Revolving Facility, and the Synthetic LC Facility are as follows:

basis (as described below); provided that such assets do not include any capital stock, notes, instruments, other equity interests of any of the Company’s subsidiaries, accounts receivable, and certain other excluded collateral as provided in the Indenture. The Senior Secured Notes are jointly and severally guaranteed on a senior secured second-lien basis by substantially all of the Company’s existing and future domestic subsidiaries. The Senior Secured Notes are not guaranteed by the Company’s foreign subsidiaries.

The Indenture provides for certain covenants, the most restrictive of which requires the Company, within 120 days after the close of each twelve-month period ending on June 30 of each year (beginning June 30, 2005) to apply an amount equal to 50% of the period’s Excess Cash Flow (as defined below) to either prepay, repay, redeem or purchase its first-lien obligations under the Revolving Facility and Synthetic LC Facility or the offer to the repurchase of all or part of the then outstanding Senior Secured Notes. “Excess Cash Flow” is defined in the Indenture as consolidated EBITDA less interest expense, all taxes paid or accrued in the period, capital expenditures made in cash during the period, and all cash spent on environmental monitoring, remediation or relating to environmental liabilities of the Company.

Revolving Facility. Both the Revolving Facility and the Synthetic LC Facility were established under a Loan and Security Agreement dated June 30, 2004 (the “Credit Agreement”) among the Company, Fleet Capital Corporation as agent for the Revolving Lenders thereunder, Credit Suisse First Boston as agent for the letter of credit facility lenders ( the “LC Facility Lenders”) thereunder, and certain other parties. The Revolving Facility allows the Company to borrow up to $30.0 million in cash, based upon a formula of eligible accounts receivable. This total is separated into two lines of credit, namely a line for the Company and its U.S. subsidiaries equal to $24.7 million and a line for the Company’s Canadian subsidiaries of $5.3 million. The Revolving Facility also allows the Company to have issued up to $10.0 million of letters of credit, with the outstanding amount of such letters of credit reducing the maximum amount of borrowings permitted under the Revolving Facility. At September 30, 2004, the Company had $0.0 million of borrowings and $1.2 million of letters of credit outstanding under the Revolving Facility, and the Company had approximately $28.8 million available to borrow. Amounts outstanding under the Revolving Facility bear interest at an annual rate of either the U.S. or Canadian prime rate or the Eurodollar rate (depending on the currency of the underlying loan) plus 1.50%. The Credit Agreement requires the Company to pay an unused line fee of 0.125% per annum on the unused portion of the Revolving Facility. The Revolving Facility matures on June 30, 2009.

Synthetic LC Facility. The Synthetic LC Facility provides that Credit Suisse First Boston (the “LC Facility Issuing Bank”) will issue up to $90.0 million of letters of credit at the Company’s request. The LC Facility requires that the LC Facility Lenders maintain a cash account (the “Credit-Linked Account”) to collateralize the Company’s outstanding letters of credit. Should any such letter of credit be drawn in the future and the Company fail to satisfy its reimbursement obligation, the LC Facility Issuing Bank would be entitled to draw upon the appropriate portion of the $90.0 million in cash which the LC Facility Lenders under the Credit Agreement have deposited into the Credit-Linked Account. Acting through the LC Facility Agent, the LC Facility Lenders would then have the right to exercise their rights as first-priority lien holders (second-priority as to receivables) on substantially all of the assets of the Company and its domestic subsidiaries. The Company has no right, title or interest in the Credit-Linked Account established under the Credit Agreement for purposes of the Synthetic LC Facility. The Company is required to pay (i) a quarterly participation fee at the annual rate of 5.35% on the average daily balance in the Credit-Linked Account and (ii) a quarterly fronting fee at the annual rate of 0.30% of the average daily aggregate amount of letters of credit outstanding under the Synthetic LC Facility. At September 30, 2004, letters of credit outstanding under the Synthetic LC facility were $89.3 million. The term of the Synthetic LC Facility will expire on June 30, 2009.

Stockholder Matters

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 were outstanding on September 30, 2004. 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. The Company paid in cash the dividends due on January 15, 2003 and April 15, 2003 but, because of restrictions in the Company’s prior debt agreements that were refinanced on June 30, 2004, the Company issued shares of the Company’s common stock in payment of the dividends due from July 15, 2003 through April 15, 2004. The Company now anticipates that dividends on the Series B Preferred Stock will be paid in cash for the foreseeable future.

New Accounting Pronouncements

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 the extent required, 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, 2004 (in thousands):

Scheduled Maturity Dates	Three Months Remaining 2004			2005			2006			2007			2008			Thereafter			Total
Senior Secured Notes	$	—		$	—		$	—		$	—		$	—		$	150,000		$	150,000
Capital Lease Obligations	375			1,490			1,454			1,047			741			95			5,202
	$	375		$	1,490		$	1,454		$	1,047		$	741		$	150,095		$	155,202
Weighted average interest rate on fixed rate borrowings	11.4		%	11.4		%	11.4		%	11.5		%	11.5		%	11.5		%

In addition to the fixed rate borrowings described in the table above, the Company has a $30.0 million Revolving Facility which bears interest at variable interest rates of either the U.S. or Canadian prime rate or the Eurodollar rate plus 1.50%, depending on the currency of the underlying loan. This total of $30.0 million is separated into two lines of credit, namely a line for the Company and its U.S. subsidiaries equal to $24.7 million and a line for the Company’s Canadian subsidiaries of $5.3 million. $0.0 of loans were outstanding under the Revolving Facility at September 30, 2004.

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 and Mexican subsidiaries as long-term; thus, the Company has not entered into any hedging transactions between the Canadian dollar and the U.S. dollar, or between the Mexican peso and the U.S. dollar. During the three- and nine-month periods ended September 30, 2004, total foreign currency losses were $623 thousand and $282 thousand, respectively, primarily between U.S and Canadian dollars. The Canadian subsidiaries transact approximately 28.7% 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 vulnerable to foreign currency translation gains or losses. During the three- and nine- month periods ended September 30, 2004, the U.S. dollar fell approximately 5.4% and 1.9%, respectively, against the Canadian dollar resulting in foreign currency losses of $622 thousand and $271 thousand, respectively. During the three- and nine-month periods ended September 30, 2003, 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 average exchange rate for the three- and nine-month periods ended September 30, 2004 was 1.32 and 1.33 Canadian dollars to the U.S. dollar, respectively. Had the Canadian dollar been 10.0% stronger against the U.S. dollar, the Company would have reported increased net income of approximately $0.5 million for the three-month period ended Septmber 30, 2004 and decreased net loss of approximately $1.0 million for the nine-month period ended September 30, 2004, respectively. Had the Canadian dollar been 10.0% weaker against the U.S. dollar, the Company would have reported decreased net income of approximately $0.5 million for the three-month period ended Septmber 30, 2004 and increased net loss of approximately $1.0 million for the nine-month periods ended September 30, 2004, 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.

Item 4. Controls and Procedures

In connection with compliance with its reporting obligations under the Securities Exchange Act of 1934, the Company maintains, evaluates and continuously improves its disclosure controls and procedures and internal controls over financial reporting. “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. “Internal controls over financial reporting” 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 accounting principles generally accepted in the United States. Section 404 of the Sarbanes-Oxley Act of 2002 (“SOX 404”) and the regulations and auditing standards subsequently adopted thereunder by the Securities and Exchange Commission (SEC) and the Public Company Accounting Oversight Board (the “PCAOB”) have imposed significantly more stringent standards for the Company’s internal controls over financial reporting than were applicable in the past.

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 over financial reporting. Prior to that acquisition, Safety-Kleen had publicly disclosed that it historically had material weaknesses 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 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 experienced certain systems and efficiency issues and the significant increase in transaction volume and the number of new users of the Company’s systems increased the risk of human error or mistake during the integration period. 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 are substantially integrated and efficiently operating as of September 30, 2004.

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, 2003, PricewaterhouseCoopers LLP (“PwC”) advised the Audit Committee of the Company’s Board of Directors, and the 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, 2003, PwC noted a material weakness existed in the reconciliation and calculation of deferred revenue. That material weakness arose in connection with the Company’s acquisition of incineration facilities as part of the CSD assets due to the lack of proper integration of legacy incineration management systems into the Company’s billing and waste management system. PwC also noted that reportable conditions existed for environmental and landfill accounting, valuation of unbilled receivables, fixed asset accounting and income tax accounting.

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 correct the material weakness and the reportable conditions referenced above and to ensure that these internal control deficiencies have not and do not lead to any material misstatement in its consolidated financial statements or significant delay in the completion of audits of its consolidated financial statements. In particular, with respect to that material weakness, the Company instituted new procedures and developed new computer reports to insure that all waste on site is valued and properly deferred. With respect to those reportable conditions, the Company has developed written procedures to document the processes and controls; the Company has hired additional accounting personnel; and the Company has increased its management oversight over those areas. While these corrective actions have generally been completed, further efforts to enhance the Company’s systems and internal controls over financial reporting are ongoing.

In light of this information, 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. 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 effective for these purposes as of September 30, 2004, the Company should continue its efforts to further improve its disclosure controls and procedures.

SOX 404 and the SEC and PCAOB regulations and auditing standards adopted thereunder require that management document and test the Company’s internal controls over financial reporting and assert in the Company’s Annual Report on Form 10-K for the year ended December 31, 2004, whether such internal controls are effective as of December 31, 2004. Management would be precluded from asserting that such internal controls are “effective” as of December 31, 2004 if either there then exists any “material weakness” in such internal controls or such controls have not by then been adequately documented and tested. Since early 2003, the Company’s financial personnel have treated as a major priority the correcting of systems and efficiency issues brought about by the CSD acquisition and the documentation of the Company’s internal controls over financial reporting. To assist in this process, the Company hired in February 2004 a full-time Section 404 Project Director and a consulting firm with expertise in SOX 404 compliance. The Company is still in the process of documenting and testing its internal controls and remediating deficiencies to the extent required. Management is striving to complete this process by December 31, 2004 so that management will be able to make a positive assertion as to the effectiveness of internal controls over financial reporting as of December 31, 2004. However, due to the limited time remaining and the magnitude of the task, there is a risk that the Company will not be able to complete this process by December 31, 2004 and be able to assert that the internal controls over financial reporting as of December 31, 2004 are “effective” as that term is used in SOX 404 and the SEC and PCAOB regulations and auditing standards adopted thereunder. Also, there is a risk that PwC will not be able to complete their testing of the Company's internal controls over financial reporting in order to be able to provide an opinion that the controls are "effective" as of December 31, 2004.

Other than the ongoing actions described above, there have been no significant changes in the Company’s internal controls over financial reporting or in other factors that could significantly affect these controls subsequent to the date of their evaluation.
