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” in this report.

Certain reclassifications have been made in the prior period’s Consolidated Financial Statements to conform with the presentation for the period ended March 31, 2004.

(2) Acquisition

As more fully described in the 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

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.

CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(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 has 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 income (loss) per common share for the quarters ended March 31, 2004 and 2003, would approximate the pro forma amounts as compared to the amounts reported (dollars in thousands except for per share amounts):


	Three Months Ended March 31,

Net income (loss) attributable to common shareholders	$	1,962		$	(8,006	)
Deduct: Total stock-based employee compensation expense determined under fair value-based method for all awards net of related tax effects		512			336

Pro forma net income (loss)	$	1,450		$	(8,342	)


Earnings (loss) per share:
Basic as reported	$	0.14		$	(0.60	)
Basic pro forma		0.10			(0.63	)

Diluted as reported	$	(0.08	)	$	(0.60	)
Diluted pro forma		(0.11	)		(0.63	)

(4) Properties Held For Sale

As part of its plan to integrate the activities of the CSD into its operations, the Company determined that certain acquired properties were no longer needed for 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. 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.

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 selling, general and administrative expenses.

Less obligations classified as current		35,153		35,291

Long-term obligations	$	146,635	$	147,209

As described in the Annual Report on Form 10-K for the year ended December 31, 2003, the Company has outstanding a $100.0 million three-year revolving credit facility (the “Revolving Credit Facility”), $115.0 of three-year non-amortizing term loans (the “Senior Loans”) and $40.0 million of five-year non-amortizing subordinated loans (the “Subordinated Loans”). In addition to such financings, the Company has established a letter of credit facility (the “L/C Facility”) under which the Company may obtain up to $100.0 million of letters of credit by providing cash collateral equal to 103% of the amount of such outstanding letters of credit.

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

Revolving Credit Facility. The Revolving Credit Facility was established under a Loan and Security Agreement dated September 6, 2002, as subsequently amended (the “Revolving Credit Agreement”) between the Company and Congress Financial Corporation (New England) as Lender and as Agent for the other Lenders thereunder. The Revolving Credit Facility allows the Company to borrow up to $100.0 million in cash and letters of credit, based upon a formula of eligible accounts receivable. This total is separated into two lines of credit, namely a line for the Company’s Canadian Subsidiaries of $20.0 million in Canadian dollars and a line for the Company and its U.S. subsidiaries equal to $100.0 million in U.S. dollars less the then conversion value of the Canadian line. Letters of credit outstanding at any one time under the Revolving Credit Facility may not exceed $20.0 million. At March 31, 2004, letters of credit outstanding were $3.5 million and the Company had approximately $35.1 million available to borrow. The Revolving Credit Agreement, as most recently amended, allows for up to 80% of the outstanding balance of the loans to bear interest at an annual rate of LIBOR plus 3.50%, with the balance at either U.S. or Canadian prime (as appropriate) plus 0.50%. The Revolving Credit Agreement requires the Company to pay an unused line fee of 0.25% per annum on the unused portion of the revolving credit. Even though the Revolving Credit Facility is due in September 2005, it is classified as short-term debt since the Revolving Credit Agreement contains both a subjective acceleration clause and a lockbox arrangement whereby remittances from the Company’s customers are directed to reduce the debt outstanding.

CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Under the terms of the Revolving Credit Agreement, as amended, the Company was required to maintain consolidated earnings before interest, taxes, depreciation and amortization (“EBITDA”) (as described below) of not less than $43.7 million for the three-quarter period ended March 31, 2004. For the three-quarter period ended March 31, 2004, EBITDA was $44.6 million which was within covenant. The Company was also required to maintain a fixed charge coverage ratio of not less than 0.95 to 1.0 for the three-quarter period ended March 31, 2004. The fixed charge coverage ratio for the three-quarter period ended March 31, 2004 was 0.95 to 1.0 which was within covenant.

For the first and second quarters of 2003, the Company violated the EBITDA covenant under the Revolving Credit Facility which was cured by amending the Revolving Credit Agreement with the Second Amendment to the Loan and Security Agreement (the “Second Amendment”) and the Third Amendment to the Loan and Security Agreement (the “Third Amendment”). Under the Third Amendment, the Company is now required to maintain EBITDA of not less than $59.5 million for the four-quarter period ending June 30, 2004. The required level of EBITDA then increases in approximately equal quarterly increments to $64.6 million for the four consecutive quarter period ending December 31, 2004 and to $68.6 million for the four consecutive quarter period ending June 30, 2005. Under the Third Amendment, the Company is now required to maintain a fixed charge coverage ratio of not less than 1.0 to 1.0 for the four-quarter periods ending June 30, 2004 through December 31, 2004, 1.1 to 1.0 for the four-quarter period ending March 31, 2005, and 1.2 to 1.0 for the four-quarter period ending June 30, 2005 and each quarter thereafter.

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

up to one-half may be either paid in cash or in kind at the Company’s option). The Senior Loans and the Subordinated Loans are secured by a first security or mortgage interest in substantially all of the Company’s assets, except for the second security interests in the Company’s accounts receivable in which the Agent under the Revolving Credit Facility has a first security interest and the cash collateral provided by the Company to the issuer of letters of credit under the L/C Facility in which such issuer has a first security interest.

The Financing Agreement, as amended, provides for certain covenants, the most restrictive of which required that the Company maintain minimum consolidated EBITDA (as described below) of not less than $53.1 million for the four-quarter period ended March 31, 2004. For the four-quarter period ended March 31, 2004, EBITDA was $54.1 million which was within covenant. The Company was also required to maintain a fixed charge coverage ratio of not less than 0.87 to 1.0 for the four consecutive quarter period ended March 31, 2004. For the four consecutive quarter period ended March 31, 2004, the fixed charge coverage ratio was 0.99 to 1.0 which was within covenant. The Company was also required to maintain a leverage ratio of consolidated funded indebtedness to consolidated EBITDA of not more than 2.23 to 1.0 for the four consecutive quarter period ended March 31, 2004. For the four consecutive quarter period ended March 31, 2004, the leverage ratio was 1.8 to 1.0 which was within covenant.

For the first and second quarters of 2003, the Company violated certain of the loan covenants under the Senior Loans and Subordinated Loans which was cured by amending the Financing Agreement with the First Amendment to Financing Agreement (the “First Financing Amendment”) and the Second Amendment to Financing Agreement (the “Second Financing Amendment”). The Company is now required to maintain consecutive four quarters EBITDA of not less than $59.5 million, $61.7 million and $64.6 million for the periods ending June 30, 2004, September 30, 2004 and December 31, 2004, respectively. The required level of EBITDA then increases in approximately equal quarterly increments to $80.3 million, $90.9 million, and $107.1 million for the years ending December 31, 2005, 2006 and 2007, respectively. The Company is also now required to maintain a fixed charge coverage ratio of not less than 1.0 to 1.0, 1.05 to 1.0 and 1.12 to 1.0 for the four consecutive quarter periods ending June 30, 2004, September 30, 2004 and December 31, 2004, respectively. The required fixed charge coverage ratio then increases in approximately equal quarterly increments to 1.33 to 1.0, 1.43 to 1.0 and 1.55 to 1.0 for the four-quarter periods ending December 31, 2005, 2006 and 2007, respectively. The Company is also now required to maintain a leverage ratio of not more than 1.80 to 1.0, 1.79 to 1.0 and 1.65 to 1.0 for the four-quarter periods ending June 30, 2004, September 30, 2004 and December 31, 2004, respectively. The maximum leverage ratio then decreases in approximately equal quarterly increments to 0.98 to 1.0, 0.62 to 1.0, and 0.21 to 1.0 for the four-quarter periods ending December 31, 2005, 2006 and 2007, respectively.

In exchange for the lenders waiving the violation of the loan covenants for the first and second quarters of 2003 and resetting the loan covenants for future periods, the First Financing Amendment and the Second Financing Amendment required the Company to pay amendment fees totaling approximately $1.0 million in fiscal year 2003. In addition, even though the Company was in compliance with its loan covenants for the third and fourth quarters of 2003, in accordance with the Second Financing Amendment the Company paid an additional amendment fee of $0.6 million in April 2004 because the Company failed to achieve 95% of its projected consolidated EBITDA benchmark for the period commencing July 1, 2003 through December 31, 2003. These amendment fees were capitalized and are being amortized over the life of the debt. The Second Financing Amendment increased the interest rates from those of the Financing Agreement for Senior and Subordinated Loans from LIBOR plus 7.25% to LIBOR plus 7.75% and from 22.0% to 22.5%, respectively. The Amendments to the Financing Agreement also prohibit the Company from paying dividends in cash on its Series B Preferred Stock and Series C Redeemable Preferred Stock, and prohibit the repurchase or retirement of outstanding common stock, preferred stock, warrants and stock options.

L/C Facility. At March 31, 2004, letters of credit outstanding under the L/C Facility were approximately $86.2 million.

EBITDA. In addition to disclosing financial results that are determined in accordance with generally accepted accounting principles (“GAAP”), the Company also uses the non-GAAP measure EBITDA. 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. In addition to the inclusion of EBITDA in the loan covenants, the number of common shares into which the Company’s Series C Convertible Preferred Stock can be converted into was dependent on the level of EBITDA attained during the year ended December 31, 2003. 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 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.

(6) Legal Proceedings and Contingencies

General Environmental Matters

The Company’s waste services are continuously regulated by federal, state, provincial and local laws enacted to regulate discharge of materials into the environment, remediation of contaminated soil and groundwater or otherwise protect the environment. This ongoing regulation results in the Company frequently becoming a party to judicial or administrative proceedings involving all levels of governmental authorities and other interested parties. The issues involved in such proceedings generally relate to applications for permits and licenses by the Company and conformity with legal requirements, alleged violations of existing permits and licenses or requirements to clean up contaminated sites. At March 31, 2004, the Company was involved in various proceedings the principal of which are described below, in which a governmental authority is a party relating primarily to activities at or shipments from the Company’s waste treatment, storage and disposal facilities.

Legal Proceedings Assumed in Connection with Acquisition of CSD Assets

Effective September 7, 2002 (the “Closing Date”), the Company purchased from Safety-Kleen Services, Inc. and certain of its domestic subsidiaries (collectively, the “Sellers”) substantially all of the assets of the Chemical Services Division (the “CSD”) of Safety-Kleen Corp. (“Safety-Kleen”). The Company purchased the CSD assets pursuant to a sale order (the “Sale Order”) issued by the Bankruptcy Court for the District of Delaware which has jurisdiction over the Chapter 11 proceedings involving the Sellers, and the Company therefore took title to the CSD assets without assumption of any liability (including pending or threatened litigation) of the Sellers except as expressly provided in the Sale Order. However, under the Sale Order (which incorporated by reference certain provisions of the Acquisition Agreement between the Company and Safety-Kleen Services, Inc.), the Company became subject to certain legal proceedings involving the CSD assets for three reasons as described below. As of

CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

March 31, 2004, the Company had reserves of $22.7 million (substantially all of which the Company had established as part of the purchase price for the CSD assets) relating to the Company’s estimated potential liabilities in connection with such legal proceedings. The Company periodically adjusts the aggregate amount of such reserves when such potential liabilities are paid or otherwise discharged or additional relevant information becomes available to the Company.

The first reason for the Company’s assumption of certain legal proceedings in connection with the acquisition of the CSD assets is that, as part of the CSD assets, the Company acquired all of the outstanding capital stock of certain Canadian subsidiaries (the “CSD Canadian Subsidiaries”) formerly owned by the Sellers (which subsidiaries were not part of the Sellers’ bankruptcy proceedings), and the Company therefore became subject to the legal proceedings (which include the Ville Mercier Legal Proceedings described below) in which the Canadian Subsidiaries are now or may in the future become involved. The second reason is that there are ongoing legal proceedings (which include the FUSRAP Legal Proceedings described below) which, while the Company will not be responsible for damages or other liabilities of the Sellers relating to such proceedings, may nevertheless affect the future operation of certain of the CSD assets. The third reason is that, as part of the purchase price for the CSD assets, the Company agreed with the Sellers that the Company will assume and pay certain current and future liabilities of the Sellers under applicable federal and state environmental laws including, in particular, the Sellers’ share of certain cleanup costs payable to governmental entities under the federal Comprehensive Environmental Response, Compensation and Liability Act (“Superfund Act”) or analogous state Superfund laws.

The principal legal proceedings which the Company assumed in connection with its acquisition of the CSD assets are as follows. While, as described below, the Company has established reserves for certain of these matters, there can be no guarantee that any ultimate liability the Company incurs for any of these matters will not exceed the amount of the current reserves or that the Company will not incur other material expenditures.

Ville Mercier Legal Proceedings. One of the CSD Canadian Subsidiaries (the “Mercier Subsidiary”) owns and operates a hazardous waste incinerator in Ville Mercier, Quebec (the “Mercier Facility”). A portion of the Mercier Facility is now contaminated as a result of actions dating back to 1968, when the Quebec government issued to the unrelated company which then owned the Mercier Facility two permits to dump organic liquids into lagoons on the property. By 1972, groundwater contamination had been identified, and the Quebec government provided an alternate water supply to the municipality of Ville Mercier.

In 1999, Ville Mercier and three neighboring municipalities filed separate legal proceedings against the Mercier Subsidiary and certain related companies together with certain former officers and directors, as well as against the Government of Quebec. The lawsuits assert that the defendants are jointly and severally responsible for the contamination of groundwater in the region, which the plaintiffs claim was caused by contamination from the former Ville Mercier lagoons and which they claim caused each municipality to incur additional costs to supply drinking water for their citizens since the 1970’s and early 1980’s. The four municipalities claim a total of $1.6 million (CDN) as damages for additional costs to obtain drinking water supplies and seek an injunctive order to obligate the defendants to remediate the groundwater in the region. The Quebec Government also sued the Mercier Subsidiary to recover approximately $17.4 million (CDN) of alleged past costs for constructing and operating a treatment system and providing alternative drinking water supplies. The Mercier Subsidiary continues to assert that it has no responsibility for the groundwater contamination in the region.

Because the continuation of such proceedings by the Mercier Subsidiary, which the Company now owns, will require the Company to incur legal and other costs and the risks inherent in any such litigation, the Company, as part of its integration plan for the CSD assets, decided to vigorously review options which would

CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

allow the Company to establish harmonious relations with the local communities, resolve the adversarial situation with the Provincial government and spare continued legal costs. Based upon the Company’s review of likely settlement possibilities, the Company now anticipates that as part of any such settlement it will likely agree to assume at least partial responsibility for remediation of certain environmental contamination and certain prior costs. At March 31, 2004, the Company had accrued $9.6 million for remedial liabilities and associated legal costs relating to the Ville Mercier Legal Proceedings.

FUSRAP Legal Proceedings. As part of the CSD assets, the Company acquired a hazardous waste landfill in Buttonwillow, California (the “Buttonwillow Landfill”). During 1998 and 1999, the Seller’s subsidiary which then owned the Buttonwillow Landfill (the “Buttonwillow Seller”) accepted and disposed in the Buttonwillow Landfill certain construction debris (the “FUSRAP Wastes”) that originated at a site in New York that was part of the federal Formerly Utilized Sites Remedial Action Program (“FUSRAP”). FUSRAP was created in the mid-1970’s in an attempt to manage various sites around the country contaminated with residual radioactivity from activities conducted by the Atomic Energy Commission and the United States military during World War II. The FUSRAP Wastes are primarily construction and demolition debris exhibiting low-activity residual radioactivity that were shipped to the Buttonwillow Landfill by U.S. Army Corps of Engineers.

The California Department of Health Services (“DHS”) has claimed in a letter to the Buttonwillow Seller that the Buttonwillow Seller did not lawfully accept the FUSRAP Wastes under applicable California law and regulations. Both DHS and the California Department of Toxic Substances Control (“DTSC”) filed claims in the Sellers’ bankruptcy proceedings preserving the right of those agencies to claim penalties for damages against the Buttonwillow Seller and possibly seeking to compel removal of the FUSRAP Wastes from the Buttonwillow Landfill. However, the specified agencies are still investigating whether they believe the Buttonwillow Seller violated any California law or regulation and, aside from the letter to the Buttonwillow Seller and the filing of the proofs of claim in the Sellers’ bankruptcy proceedings, the California agencies have not commenced any enforcement proceedings relating to the Buttonwillow Landfill. However, in November 2003, a California non-profit corporation allegedly acting under the California Unfair Business Practices Act added the Company (as the current owner of the Buttonwillow Landfill) as a defendant to a lawsuit which that corporation had originally brought in 2000 against certain of the Sellers in the California Superior Court for the County of Los Angeles. That lawsuit seeks, among other matters, an order requiring the named defendants (which now include the Company) to remove the FUSRAP Wastes from the Buttonwillow Landfill and to dispose of this material at a facility licensed for disposal of radioactive waste.

Under the Sale Order, the Company is not liable for penalties, if any, which the Buttonwillow Seller might ultimately be determined to owe to the DHS and DTSC, but the Company could potentially be liable for removal costs if such agencies or the non-profit corporation described above were ultimately to obtain a final non-appealable order determining that the FUSRAP Wastes were improperly disposed of at the Buttonwillow Landfill and directing that such wastes be removed. The Company now estimates the cost of removing the FUSRAP Wastes from the Buttonwillow Landfill would be approximately $6.9 million. However, both the Sellers and the Company believe that the FUSRAP Wastes were properly, safely and lawfully disposed of at the Buttonwillow Landfill under all applicable laws and regulations and they will vigorously resist any efforts to require that such wastes be removed. In addition, the Company believes that the California state court in the suit brought by the non-profit corporation under the California Unfair Business Practices Act described above (which is currently the only pending legal proceeding relating to the FUSRAP Wastes to which the Company is a party) could not properly grant any order requiring the Company to remove the FUSRAP Wastes. Although the Company has established reserves to cover its estimated legal costs to be incurred in connection with this legal proceeding, the Company has not accrued any costs of removing the FUSRAP Wastes because the Company believes that only a remote possibility exists that a final order will be issued requiring the Company to remove such wastes.

Tanner Act Proceeding. In 1999 the Conditional Use Permit (“CUP”) issued by Kern County, California for the Seller’s Buttonwillow Landfill was challenged by a local interest group, Padres Hacia Una Lina Vida Mejor and its individual members. The proceeding was initiated under the Tanner Act, a unique California statute that enables citizens to appeal local land use decisions regarding hazardous waste facilities under California Health and Safety Code Section 25199-25199.14. Under the Tanner Act, the Governor or a designee, upon making certain findings, must appoint a 7-member Appeal Board that is empowered to convene hearings and if necessary require the local agency to modify its land use decision in accordance with the Appeal Board decision.

In the Buttonwillow proceeding, the preliminary hearings were held intermittently from November 2001 through May 2002. The Appeal Board issued its preliminary hearing decision on July 18, 2002. The Appeal Board rejected nine of the ten issues submitted to it by the petitioners. The Appeal Board decided that one issue should proceed to a full hearing, namely Issue Y, which challenges a permit condition that establishes certain limits on the disposal of radioactive waste at the facility. For the past year the Company has engaged in intermittent settlement negotiations with the attorneys for the petitioners. On April 9, 2004, the Company reached a settlement with the group whereby the Company agreed to establish voluntary limits on the disposal of radioactive waste at the facility and agreed, among other things, to certain monitoring mechanisms on incoming waste at the facility (which the Company anticipates will not have a material adverse effect on the facility’s operations) and reporting procedures on the results of that monitoring of incoming wastes. The parties agreed to present the settlement agreement to the Appeal Board with a joint request for a dismissal of the action when Kern County modifies the CUP to incorporate the provisions of the settlement agreement. As a result of the settlement, the Company recorded a gain of $0.3 million in the quarter ended March 31, 2004.

Assumption of Certain CSD Superfund Liabilities. The Company’s agreement to pay as part of the purchase price for the CSD assets the Sellers’ share of certain cleanup costs payable to governmental entities under federal and state Superfund laws relate primarily to (i) certain potential liabilities which the Sellers might incur in the future in connection with an incinerator formerly operated by Marine Shale Processors to which the Sellers shipped hazardous wastes, (ii) two properties included in the CSD assets which are now subject to Superfund proceedings and for which one or more of the Sellers has been designated a Potentially Responsible Party (“PRP”), (iii) 35 active Superfund sites owned by third parties where the Sellers have been designated as PRPs, and (iv) several inactive Superfund sites owned by third parties where the Sellers have been named as PRPs but as to which the Sellers and the Company believe the Sellers have no significant liabilities.

Federal and state Superfund laws generally impose strict, and in certain circumstances, joint and several liability for the costs of cleaning up Superfund sites not only upon the owners and operators of such sites, but also upon persons or entities which in the past have either generated or shipped hazardous wastes which are present on such sites. The Federal Superfund law also provides for liability for damages to natural resources caused by hazardous substances at such sites. Accordingly, the Superfund laws encourage PRPs to agree to share in specified percentages of the aggregate cleanup costs for Superfund sites by entering into consent decrees, settlement agreements or similar arrangements. Non-settling PRPs may be liable for any shortfalls in government cost recovery and may be liable to other PRPs for equitable contribution. Under the Superfund laws, a settling PRP’s financial liability could increase if the other settling PRPs were to become insolvent or if additional or more severe contamination were discovered at the relevant site. In estimating the amount of those Sellers’ liabilities which the Company has agreed to assume for cleanup costs at Superfund sites where one or more of the Sellers has been designated as a PRP, the Company therefore reviewed any existing consent decrees, settlement agreements or similar arrangements with respect to those sites, the Sellers’ negotiated volumetric share of liability (where applicable), the Company’s prior knowledge of the relevant sites, and the Company’s general experience in dealing with the cleanup of Superfund sites.

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

Although the Sellers never held an equity interest in Marine Shale, the Sellers were among the largest customers of Marine Shale in terms of overall incineration revenue. If the EPA or the Louisiana Department of Environmental Quality (“LDEQ”) were to designate the Marine Shale facility and/or the Recycling Park, Inc. site as a Superfund site or sites, the Sellers could be exposed to liability for cleanup costs as PRPs and, in such event, the Company could be obligated to pay all or a portion of such costs in accordance with the Company’s agreement described above to assume certain of the Sellers’ Superfund liabilities to governmental entities as part of the purchase price for the CSD assets. Based on a plan to settle obligations that was established at the time of the acquisition, the Company obtained more complete information as to the potential status of the Marine Shale facility and the Recycling Park, Inc. site as a Superfund site or sites, the potential costs associated with possible removal and disposal of some or all of the vitrified aggregate and closure and remediation of the Marine Shale facility and the Recycling Park, Inc. site, and the respective shares of other identified potential PRPs on a volumetric basis. Accordingly, the Company has determined that the remedial liabilities and associated legal costs are now probable and estimable, and the Company recorded liabilities for the Company’s estimate of the Sellers’ proportionate share of environmental cleanup costs potentially payable to governmental entities under federal and/or state Superfund laws. At March 31, 2004, the Company had accrued $13.9 million relating to Marine Shale facility and the Recycling Park, Inc. site.

Properties Included in CSD Assets. The two properties included in the CSD assets which are now subject to Superfund proceedings and for which one or more the Sellers has been designated as a PRP are located at 2549 North New York Street in Wichita, Kansas (the “North New York Street Property”), and at 411 Burton Road in Lexington, South Carolina (the “Burton Road Property”). The North New York Street Property is an active service center which is one of several properties located within the boundaries of a 1,400 acre state designated Superfund site in an old industrial section of Wichita known as the North Industrial Corridor Site. The Sellers have executed a consent decree relating to such site with the EPA, and the Company will continue its ongoing remediation program for the North New York Street Property. Included within the CSD assets acquired by the Company are rights under an indemnification agreement between the Sellers and a prior owner of the North New York Street Property which the Company anticipates but cannot guarantee will be available to reimburse certain cleanup costs.

CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The Burton Road Property is now vacant but was formerly operated by the Sellers as a waste transfer and truck cleaning facility, and the property is located within the boundaries of a state designated Superfund site known as the Hollis Road Site. In June 2000, the South Carolina Department of Health and Environmental Control (“DHEC”) initiated a lawsuit against the Sellers and two other parties that owned or operated facilities within the Hollis Road Site boundaries. On February 7, 2003 the Company and two subsidiaries of the Seller entered into a Consent Decree with the DHEC, which has been approved by the United States District Court, settling the South Carolina claims and lawsuit with respect to the Hollis Road Superfund site and the Burton Road Property. The Consent Decree provides that the Company must make two installment payments to DHEC. The Consent Decree contains a customary covenant not to sue and contribution protection provisions for the Company, and also contains a limited “re-opener” provision. The re-opener provision would require the Company to perform soils remediation work within the boundaries of its Burton Road Property if new releases or spills were to occur or if there was independently verifiable data to substantiate that a specified contaminant or its degradation products were discovered above certain concentration levels in the soils at the Burton Road Property. At this time the Company is aware of no data which identifies such contamination at the Burton Road property. At March 31, 2004, the Company had reserves totaling $4.3 million relating to its liabilities at the North New York Street Property and the Burton Road Property.

The CSD assets also 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 Federal United States EPA pursuant to the Superfund Act concerning the Devil’s Swamp Lake Site (“Devil’s Swamp”) in East Baton Rouge Parish, Louisiana. On March 8, 2004, the EPA proposed to list Devil’s Swamp on the National Priorities List for further investigations and possible remediation. Devil’s Swamp includes a lake, located downstream of an outfall ditch where waste waters and stormwaters have been discharged from the BR Facility, as well as extensive swamplands adjacent to it. Contaminants of concern cited by the EPA as a basis for listing the site 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 Company is identified as a PRP at Devil’s Swamp, additional action will not be required and that the Company will not incur material costs.

Active Third Party Superfund Sites. Prior to the Closing Date, the Sellers had generated or shipped hazardous wastes which are present on an aggregate of 35 sites owned by third parties which have subsequently been designated as federal or state Superfund sites and at which the Sellers, along with other parties, have been designated as PRPs. At 30 of those sites, the Sellers have addressed their cleanup obligations to the federal and state governments and to other PRPs by entering into consent decrees or other settlement agreements or by participating in ongoing settlement discussions or site studies and, in accordance therewith, the PRP group is generally performing or has agreed to perform the site remediation program with government oversight. Of the five remaining active sites at which one or more of the Sellers has been designated as a PRP, the Company on behalf of the Sellers is contesting liability at two sites and plans to fund participation by the Sellers as settling PRPs at three sites. For the 35 sites, the Company had reserves of $20.4 million at March 31, 2004.

Inactive Third Party Superfund Sites. In addition to the active Superfund sites owned by third parties, the Sellers have also been identified as PRPs at several other federal or state Superfund sites owned by third parties which the Company believes are now inactive with respect to the Sellers. The inactive sites generally involve the shipment by the Sellers of a de minimis amount of wastes to such sites and prior consent decrees, settlement agreements or similar arrangements providing for minimal payment obligations by the Sellers. De minimis agreements generally are intended to settle all claims for small PRPs and such agreements have limited “re-opener” provisions. At certain other inactive sites, the Sellers have disclaimed any liability by advising the

CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

governmental entities involved that the Sellers had not shipped any wastes to those sites. The Company has not established reserves for any of the inactive sites because the Company believes that the Sellers’ cleanup liabilities with respect to those sites have already been resolved.

Other Legal Proceedings Related to CSD Assets

In addition to the legal proceedings which the Company assumed in connection with the acquisition of the CSD assets, one lawsuit has been filed against the Company subsequent to the acquisition based in part upon allegations relating to the Company’s current operations of a former CSD facility. In December 2003, a lawsuit was filed in the 18^th Judicial District Court in Iberville Parish, Louisiana, against the Company’s subsidiary which acquired and now operates a deep injection well facility near Plaquemine, Louisiana. This lawsuit was brought under the citizen suit provisions of the Louisiana Environmental Quality Act. The lawsuit alleges that the facility is in violation of state law by disposing of hazardous waste into an underground injection well that the plaintiffs allege is located within the banks or boundaries of a body of surface water within the jurisdiction of the State of Louisiana. The lawsuit also focuses on a “new area of concern” at the facility which the plaintiffs allege is a source of contamination which will require environmental remediation and/or restoration. The lawsuit also alleges that the Company’s former facility manager made false representations and failed to disclose material information to the regulators about the site after the Company acquired it in September 2002. The plaintiffs seek an order declaring the injection well to be located within the banks or boundaries of a body of surface water under state law, payment of civil penalties, and an additional penalty of $1.0 million for damages to the environment, plus interest. The plaintiffs also seek an order requiring the facility to remove all waste disposed of since September of 2002, and in general, to conduct an investigation into and remediate the alleged contamination at the facility, as well as damages for alleged personal injuries and property damage, natural resources damages, costs of litigation, and attorney’s fees.

The Company believes this lawsuit is without merit, and intends to fully and vigorously defend against the claims made. The Company further believes that, since its acquisition by the Company, the Plaquemine facility has been and now is in full compliance with its operating permits and all applicable state laws, and that any alleged contamination in the “new area of concern” complained of by the plaintiffs was and is already being addressed under the corrective action provisions of its RCRA operating permit. In addition, the Company believes that many of the plaintiffs’ claims relate to actions or omissions allegedly taken or caused by third parties that formerly owned and/or operated, or generated or shipped waste to, the Plaquemine facility for which the Company has no legal responsibility under the Sale Order. Although the Company has established reserves to cover its estimated legal costs to be incurred in connection with this proceeding, this litigation is in its very preliminary stages and the Company is therefore unable to estimate any other potential liability relating to the lawsuit.

In addition to the legal proceedings in which the Company became involved as a result of its acquisition of the CSD assets, the Company is also involved in certain legal proceedings which have arisen for other reasons. The principal such legal proceedings include certain federal securities class action litigation, certain Superfund proceedings relating to sites owned by third parties where the Company (or a predecessor) has been named a PRP, certain EPA and state regulatory proceedings, and litigation involving the former holders of the Company’s subordinated notes.

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

CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Court for the District of Massachusetts 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 Securities and Exchange Commission (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 of the Company’s public announcements the Company 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 included in those announcements, 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. The Company anticipates that these actions will be consolidated during the second quarter of 2004, after which the Company will file its formal legal response to the consolidated suit.

The Company believes that at all times during the purported class period the Company and the two other defendants 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 contest 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.

Superfund Sites Not Related to CSD Acquisition. The Company has been named as a PRP at 28 sites that are not related to the CSD acquisition. Fourteen of these sites involve two subsidiaries, which the Company acquired from ChemWaste, a former subsidiary of Waste Management, Inc. As part of that acquisition, ChemWaste agreed to indemnify the Company with respect to any liability of its Braintree and Natick subsidiaries for waste disposed of before the Company acquired them. Accordingly, Waste Management is paying all costs of defending the Company’s Braintree and Natick subsidiaries in these 14 cases, including legal fees and settlement costs.

The Company’s subsidiary which owns the Bristol, Connecticut facility is involved in one of the 28 Superfund sites. As part of the acquisition of the Bristol, Connecticut and Cincinnati, Ohio facilities, the seller and its now parent company, Cemex, S.A., agreed to indemnify the Company with respect to any liability for waste disposed of before the Company acquired the facilities, which would include any liability arising from Superfund sites.

Six of the 28 sites involve former subsidiaries of ChemClear Inc. Some of these sites have been settled, and the Company believes its ultimate exposure with respect to the remaining such sites will not be material to the Company’s result of operations, cash flow from operations or financial position.

In July 1992, the Company acquired a transportation company which is involved in four of the 28 sites, as a transporter of waste generated by others prior to the Company’s purchase of that transportation company. The Company acquired that transportation company in exchange for 233,000 shares of the Company’s common stock, of which 33,222 shares were deposited into an escrow account to be held as security for the sellers’ agreement to indemnify the Company against potential undisclosed liabilities, including environmental liabilities arising from prior ownership and operation of that transportation company. The Company anticipates those escrow shares will be released during 2004 since no additional environmental claims have been asserted against the Company.

CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

One of the 28 sites relates to Murphy’s Waste Oil Services, Inc., which the Company acquired in 1989. The Company has been identified as a PRP at two other of the 28 sites, but the Company believes that it has no liability at those sites.

As of March 31, 2004, the Company had reserves of $0.2 million for cleanup of Superfund sites not related to the CSD acquisition at which either the Company or a predecessor has been named as a PRP. However, there can be no guarantee that the Company’s ultimate liabilities for these sites will not exceed this amount or that indemnities applicable to any of these sites will be available to pay all or a portion of related costs.

EPA Enforcement Actions:

Kimball Facility. On April 2, 2003, Region VII of the U.S. Environmental Protection Agency (“EPA Region VII”) in Kansas City, Kansas, served a Complaint, Compliance Order and Notice of Opportunity for Hearing (“CCO”) on the Company’s subsidiary which operates an incineration facility in Kimball, Nebraska. The CCO stems from an inspection of the Kimball facility between April 8-10, 2002. Thereafter, EPA Region VII issued a Notice of Violation (“NOV”) for certain alleged violations of RCRA. The Company responded to the NOV by letter and contested the allegations. The EPA alleges, among other things, that the facility had open containers of incinerator ash in the ash stabilization building, stored incompatible wastes without adequate separation, and failed to label equipment in hazardous waste service. After extensive settlement negotiations, on February 23, 2004, the Company and EPA Region VII executed a Consent Agreement and Final Order that included a Supplemental Environmental Project (“SEP”). The Company will be required to perform and account for the SEP in accordance with the EPA’s SEP Policy. The SEP will involve cleaning out chemicals from high school laboratories, art departments and other campus locations, with all such work to be performed by the Company’s own trained field chemists. The SEP will also include the proper packaging, labeling, manifesting, transportation, and ultimately disposal, recycling or re-use of these chemicals at the hazardous waste treatment, storage and disposal facilities owned and operated by the Company’s subsidiaries, in lieu of the payment of any further civil penalties. The Company will have two years to complete the performance of the SEP, and any remaining amounts then still owed and outstanding will have to be paid in cash at that time, as calculated pursuant to a sliding scale formula that reduces the amount of cash that will be owed as more of the environmental services are rendered over the two-year period. At March 31, 2004, the Company had accrued $132 thousand for its SEP liability.

Chicago Facility. By letter dated January 16, 2004, Region V of the EPA (“EPA Region V”) in Chicago, Illinois notified the Company that EPA Region V believes the Company’s Chicago, Illinois facility may be in violation of the National Emission Standard for Benzene Waste Operations Subpart FF regulations promulgated under the Clean Air Act and that EPA Region V may seek injunctive relief and civil penalties for these alleged violations. The alleged violations pertain to total annual benzene quantity determinations and reporting, provisions of individual waste stream identification and emissions control information, and treatment and control requirements for the benzene waste streams. EPA Region V is seeking a fine of $325 thousand. The Company believes that its Chicago facility complies in all material respects with these regulations and has engaged in ongoing settlement discussions with EPA Region V to resolve the issues described in the letter from EPA Region V without litigation. The Company does not believe that the cost of resolving this matter will be material to the Company’s results of operations or financial position.

State Enforcement Actions:

Chicago Facility. On February 12, 2004, the Company’s subsidiary which owns the Chicago facility was notified by the Illinois Attorney General’s Office that an enforcement action was being initiated against such

CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

facility. The enforcement action alleges that the Chicago facility has violated its operating permit, certain Illinois Pollution Control Board regulations, and allegedly applicable provisions of the National Emission Standards for Hazardous Air Pollutants (“NESHAPs”). The enforcement action raises allegations pertaining to adequate capture and control of air emissions, timely notification regarding the applicability and compliance status of affected air emission sources, ensuring that devices were designed to operate with no detectable organic emissions, maintaining equipment integrity, and securing off-site containers engaged in waste and recovery operations. The Illinois Attorney General’s Office announced that it was seeking $170 thousand in penalties. Legal and compliance representatives of the Company have held discussions with the Illinois Attorney General’s Office and the Illinois Environmental Protection Agency, and anticipate that a Supplemental Environmental Project will be negotiated that will substantially reduce the cash component of the penalty in exchange for agreeing to the installation of equipment upgrades at the facility designed to address and control air emissions from operations. These negotiations are ongoing, and although significant progress has been made, there can be no guarantee that a settlement can be reached or that the penalty will be reduced.

Deer Trail Landfill Facility. On March 30, 2004, the State of Colorado Department of Public Health and Environment (“CDPHE”) issued a draft Compliance Order on Consent (“COC”) and initial penalty calculation to the Company’s subsidiary which owns the Deer Trail Landfill Facility. The COC is based on findings of alleged permit and regulatory violations by the CDPHE during on-site inspections, and the CDPHE has initially calculated a penalty in the amount of $132 thousand. CDPHE has indicated its desire to settle the matter with the Company. Legal and compliance representatives of the Company have been negotiating with the Colorado Attorney General’s Office and the CDPHE, and anticipate that a Supplemental Environmental Project (“SEP”) will be negotiated that will substantially reduce the cash component of the penalty in exchange for performance of the SEP. These negotiations are ongoing, and while discussions regarding the prospects of the SEP are also underway, there can be no guarantee that such a settlement can be reached or that the penalty will be reduced.

Contingency

Litigation Involving Former Holders of Subordinated Notes. On April 30, 2001, the Company issued to John Hancock Life Insurance Company, Special Value Bond Fund, LLC, the Bill and Melinda Gates Foundation, and certain other institutional lenders (collectively, the “Lenders”) $35 million of 16% Senior Subordinated Notes due 2008 (the “Subordinated Notes”) as part of the Company’s refinancing of all its then outstanding indebtedness. Under the Securities Purchase Agreement dated as of April 12, 2001, between the Company and the Lenders (the “Purchase Agreement”), the Company was also required to pay a $350 thousand closing fee and issue to the Lenders warrants for an aggregate of 1,519,020 shares of the Company’s common stock (the “Warrants”) exercisable at any time prior to April 30, 2008 at an exercise price of $.01 per share. The Purchase Agreement contained covenants limiting (with certain exceptions) the Company’s ability to acquire other businesses or incur additional indebtedness without the consent of a majority in interest of the Lenders. The Purchase Agreement also provided that, if the Company should elect to prepay the Subordinated Notes prior to maturity, the Company would be obligated to pay a prepayment penalty which, in the case of a prepayment prior to April 30, 2004, would include a so-called “Make Whole Amount” computed using a discount rate 2.5% above the then current yield on United States government securities of equal maturity to the Subordinated Notes. The Purchase Agreement also provided that, if the Company should default on any of the terms of the Purchase Agreement including the covenants described above, the Lenders would have the right to call the Subordinated Notes for payment at an amount equal to the principal, accrued interest and the so-called “Make Whole Amount” then in effect.

During several months prior to the Company’s acquisition of the CSD assets effective September 7, 2002, the Company sought the Lenders’ cooperation with respect to such acquisition and to include the Lenders in a

CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

refinancing of the Company’s outstanding debt (which might involve leaving the Subordinated Notes outstanding or refinancing them). The Lenders, however, ultimately refused to provide any such cooperation. The Company thus notified the Lenders that it was proceeding with the acquisition of the CSD assets, which would be a violation of certain covenants in the Purchase Agreement, and the Lenders then called the Subordinated Notes for payment, including principal, interest and the “Make Whole Amount” of $16,991,129, an amount equal to 48.5% of the principal amount of the Subordinated Notes. In response to the Lenders’ demand, the Company immediately paid in full the amount demanded, while notifying the Lenders that it was paying the “Make Whole Amount” under protest. It is the Company’s position that if the payment to the Lenders is not deemed to be voluntary and the 48.5% “Make Whole Amount” is deemed unconscionable, the “Make-Whole Amount” is likely to be held unenforceable under Massachusetts case law.

Shortly after the closing of the acquisition of the CSD assets, the Company wrote to the Lenders demanding a return of the prepayment penalty, in response to which, on September 27, 2002, the Lenders filed a complaint in the Norfolk Superior Court asking the Court to determine the prepayment penalty to be valid and enforceable. On October 1, 2002, the Company filed a complaint in the Business Litigation Session of the Suffolk Superior Court seeking a declaratory judgment that the “Make Whole Amount” is an unenforceable penalty and seeking an order for the return of the amount paid as a penalty, less the Lenders’ actual damages (if any), plus interest and costs. In the case of certain of the Lenders, the Company also seeks a judgment that those Lenders’ receipt of their share of the “Make Whole Amount,” the closing payment and the fair value of the Warrants constitutes a violation of applicable Massachusetts usury laws. The Company filed a motion seeking to consolidate both legal proceedings in the Business Litigation Session of the Suffolk Superior Court, which motion was granted. Discovery in the proceedings was completed and all parties served and filed motions for summary judgment. On March 15, 2004, the Court granted summary judgment for the Lenders ruling that the “Make Whole Amount” was enforceable. The Lenders have submitted a request for recovery of their legal and expert costs in connection with this proceeding, which were $789 thousand and $353 thousand respectively. However, the court has not ruled on this issue and a final judgment has not yet entered in the case. The Company plans to appeal the Court’s ruling. The Company has not accrued the Lenders’ legal and expert costs because the Company based on the advice of legal counsel now believes that such payment is not probable.

Commencing January 1, 2004, asset retirement obligations incurred are being discounted at the credit-adjusted risk-free rate of 8.5% and inflated at a rate of 1.2%.

(8) Redeemable Series C Preferred Stock

The Company issued the Series C Convertible Preferred Stock, $0.01 par value (“Series C Preferred Stock”), on September 10, 2002 for an aggregate of $25 million in cash to six institutional investors pursuant to a Securities Purchase Agreement dated September 6, 2002 between the Company and such investors. Subject to certain limitations, the Series C Preferred Stock will generally vote together with the Series B Convertible Preferred Stock, $0.01 par value (the “Series B Preferred Stock”), and the common stock, $0.01 par value, on all actions to be taken by the stockholders of the Company with each share of Series C Preferred Stock having the number of votes equal to the number of shares of common stock into which that share of Series C Preferred Stock is then convertible.

The Series C Preferred Stock is entitled to receive dividends at an annual rate of 6% (such dividends were paid in cash through March 2003 and accrue and compound thereafter), will be mandatorily redeemable in September 2009 at its stated value and accrued dividends, or at any time after issuance (together with accrued dividends thereon) will be convertible at the holder’s option into shares of the Company’s common stock. The conversion price was initially $10.50 per share of common stock (subject to customary adjustments for antidilution), but was reset to $8.00 per share of common stock effective as of January 1, 2004 because both (i) the Company’s Consolidated EBITDA for the year ending December 31, 2003 was less than $115 million and (ii) the average trading price for the Company’s common stock for the month of December 2003 was less than $27.50. In no event, however, will the Company be obligated to issue more shares of common stock upon the conversion of the Series C Preferred Stock than is permitted under the rules and regulations of the Nasdaq Stock Market. Accordingly, unless the Company’s common stockholders shall in the future approve the issuance of a greater number of common shares upon the conversion of the Series C Preferred Stock, the maximum number of common shares which may be issued upon conversion of the Series C Preferred Stock will be limited to 2,432,946 shares (which equals 19.99% of the total number of primary shares of the Company’s common stock outstanding on the date the Series C Preferred Stock was issued). To the extent (if any) that the purchase price of the Series C Preferred Shares, plus the amount of any accrued dividends, would otherwise be convertible into more than the number of shares permitted under Nasdaq rules, and the Company’s common stockholders shall not have approved the issuance of the excess common shares, the Company will be obligated to issue only that 2,432,946 common shares and to pay in cash to the holders of the Series C Preferred Stock the then market value of the additional common shares which cannot be issued because of the foregoing limitation.

The Company issued the Series C Preferred Stock for $25 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 consists of two components, namely (i) a

CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

non-convertible redeemable preferred stock (the “Host Contract”) which matures in 2009 with a 6% annual dividend, and (ii) an embedded derivative (the “Embedded Derivative”) which reflects the right of the holders of the Series C Preferred Stock to convert into the Company’s common stock on the terms set forth in the Series C Preferred Stock. The initial values of these two components were determined as of the issuance date based upon relative fair values using a discounted cash flow model and an assumed rate of return of 14%. Accordingly, the Series C Preferred Stock was discounted to arrive at fair value of $15.7 million for the Host Contract with the remaining cash proceeds received at issuance of $9.3 million assigned as the fair value of the Embedded Derivative. The Series C Preferred Stock reported on the Company’s consolidated balance sheet consists 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 has been recorded through the balance sheet date with regard to the $9.3 million discount which was originally recorded for the Host Contract and plus the amount of accretion for issuance costs. Such discount and issuance costs are being accreted over the life of the Series C Preferred Stock (or until the earlier conversion of the Series C Preferred Stock at the option of the holders), with such accretion being recorded as a reduction in Additional Paid-in-Capital. During the period from January 1 through March 31, 2004, the amounts of that accretion was $0.4 million. The Company recorded in Other Long-term Liabilities the $9.3 million initial fair value of the Embedded Derivative and periodically marks that value to market until such time as the maximum number of shares of common stock which may be issued upon conversion of the Series C Preferred Stock is determined. As of March 31, 2003, the market value of the Embedded Derivative was determined to be $9.2 million and the Company recorded $17 thousand of Other Income in the first quarter of 2003 to reflect such adjustment. As of March 31, 2004, the market value of the Embedded Derivative was determined to be $4.3 million and the Company recorded $5.3 million of Other Income during the first quarter of 2004 to reflect such adjustment.

The terms of the Series C Preferred Stock provide for certain covenants for the benefit of the holders thereof. Among other matters, without the approval of the holders of a majority of the outstanding shares of Series C Preferred Stock, the Company shall not be permitted to (i) pay cash dividends upon its outstanding common stock, (ii) incur indebtedness in excess of indebtedness under the Revolving Credit Facility, the Ableco Financing Agreement, the L/C Facility and certain other forms of permitted indebtedness, (iii) merge or make material acquisitions or dispositions with certain exceptions, (iv) create new classes of preferred stock, or (v) amend its charter in any manner which would have an adverse effect upon the holders of the Series C Preferred Stock. Should the Company fail to comply with these covenants and fail to cure the default within 30 days of notice from the holders of the Series C Preferred Stock, (i) the dividend rate on the Series C Preferred Stock would increase to 12% per annum until the later of (A) the six-month anniversary of the covenant default or (B) the date on which such covenant default is cured and (ii) the conversion price for the Series C Preferred Stock would decrease (subject to potential subsequent adjustments to the conversion price as described above) to an amount equal to either (A) $8.00 per share of common stock if the conversion price in effect on the date of the covenant default is greater than $8.00 per share of common stock, or (B) 90% of the conversion price in effect on the date of the covenant default if the conversion price in effect on the date of the covenant default is less than or equal to $8.00 per share of common stock.

(9) 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 months ended March 31, 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.

As further discussed in Note 8 “Redeemable Series C Preferred Stock”, the Company’s Series C Preferred stock is now convertible into more common shares than is allowed under the rules and regulations of the NASDAQ Stock Market. Because of this limitation, only that proportion of the gain on the value of the embedded derivative of shares issuable under the NASDAQ rules to the total shares of the Company’s common stock that the Series C Preferred Shares plus accrued dividends were then convertible into has been included in the calculation of diluted earnings per share for the quarter.

Because the effects would be anti-dilutive for the periods presented, the above computations of diluted earnings (loss) per share exclude the assumed conversion of the Series C Preferred Stock into 2.4 million shares for the period ended March 31, 2003, the assumed exercise of 1.8 million and 1.9 million stock options for the periods ended March 31, 2004 and 2003, respectively, the assumed conversion of the Series B Preferred Stock into 0.3 million common shares for the periods ended March 31, 2004 and 2003, and the assumed exercise of the warrants into 0.3 million shares for the period ended March 31, 2003.

(11) 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, 2004 through March 31, 2004 (in thousands):

(12) 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

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 revenues consist of revenues for miscellaneous services that are not part of a reportable segment. The Company does not allocate interest expense, income taxes, depreciation, amortization, accretion of environmental liabilities, restructuring or other acquisition costs to segments.

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”). The 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 has allowed and will continue to allow the Company to expand its service area and has resulted 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 and 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 has publicly disclosed that it had material deficiencies in many of its financial systems, processes and related internal controls. Due to the deficiencies in these systems and the Company’s belief that it would be able to utilize its own systems in order to improve the operations of the former CSD, the decision was made to integrate the U.S. operations of the former

CSD into the Company’s business and financial reporting systems effective as of the acquisition date. Although the Company has made significant progress in resolving the internal control weaknesses caused by the integration of the CSD into its systems, the Company continues to experience deficiencies in certain of its internal controls.

Acquisition

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 activity of the purchase accounting liabilities recorded in connection with the acquisition of the CSD assets (dollars in thousands):


	Severance					Facilities				Total Liability

Remaining capacity at March 31, 2004	28,897

Commencing January 1, 2004, asset retirement obligations incurred are being discounted at the credit-adjusted risk-free rate of 8.5% and inflated at a rate of 1.2%.

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 all 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 it is defined in the Financing Agreement as amended between the Company and Ableco Finance LLC, which is net income or loss, excluding interest, taxes, depreciation and amortization, accretion of environmental liabilities, restructuring charges, effects of discontinued operations, other non-recurring costs, and certain extraordinary or non-recurring gains or losses. The Company’s management considers EBITDA to be a measurement of performance which provides useful information to both management and investors. The Company’s Revolving Credit Facility, Senior Loans and Subordinated Loans outstanding as of March 31, 2004 have covenants requiring specific amounts of EBITDA, and the conversion price of the Company’s Series C Preferred Stock outstanding as of March 31, 2004 was dependent on the level of EBITDA attained during the year ended December 31, 2003.

EBITDA for under the Financing Agreement, as amended, for the four consecutive quarter period ended March 31, 2004 is calculated as follows (dollars in thousands):


Net loss	$	(7,326	)

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 months ended March 31, 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 12, “Segment Reporting” in this report.

Three months ended March 31, 2004 versus the three months ended March 31, 2003

Revenues

Total revenues for the three months ended March 31, 2004 increased $0.5 million to $142.8 million from $142.3 million for the comparable period in 2003. Technical Services revenues for the three months ended March 31, 2004 decreased $1.2 million to $101.1 million from $102.3 million for the comparable period in 2003. The decrease in revenues for Technical Services consisted primarily of a small decrease in base business due to the difficult economic environment. This was partially offset by increases in revenues from large disposal projects and the positive impact from the strengthening Canadian dollar. Pricing for waste disposal services was flat. Site Services revenues for the three months ended March 31, 2004 increased $2.7 million to $41.3 million from $38.6 million for the comparable period in 2003. Site Services revenues increased due to the opening of additional locations, and due to three emergency response jobs in 2004 for which no similar jobs were performed in 2003. Corporate Items revenues for the three months ended March 31, 2004 decreased $1.0 million to $0.4 million from $1.4 million for the comparable period in 2003. The 2003 revenues for Corporate Items consists primarily of waste existing at discontinued operating sites at the end December 31, 2002 that the Company processed in the first quarter of 2003. There was no waste at discontinued locations processed in the first quarter of 2004.

There are many factors which have impacted, and continue to impact, the Company’s revenues. These factors include: 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 March 31, 2004 increased $0.9 million to $107.5 million compared to $106.6 million for the comparable period in 2003. Technical Services costs of revenue increased $2.0 million to $78.1 million from $76.1 million for the comparable period in 2003. The increase in Technical Services costs of revenue was due to a change in the sales mix that included a greater proportion of large waste disposal jobs that typically have lower margins, higher transportation costs associated with a plan to reduce operating expenses, higher costs associated with planned maintenance which were partially offset by reduced employment costs, benefits relating to changes in estimates in environmental liabilities, and lower financial assurance costs. Site Services cost of revenue decreased $0.7 million to $28.6 million from $29.3 million for the comparable period in 2003. The reduction in Site Services cost of revenues is attributed to cost reductions achieved and the higher margin emergency response jobs performed in 2004. Corporate Items cost of revenues for the three months ended March 31, 2004 decreased to $0.7 million from $1.2 million for the comparable period in 2003. The decrease in Corporate Items cost of revenue was primarily due to reduction in activities at discontinued facilities. As a percentage of revenues, combined cost of revenues in 2004 increased for the reasons previously discussed 0.3% to 75.2% from 74.9% for the comparable period in 2003. One of the largest components of cost of revenues is the cost of disposal paid to third parties. Disposal costs paid to third parties in the first quarter of 2004 as a percentage of revenues decreased 0.4% to 4.5% from 4.9% for comparable period in 2003. This decrease in disposal expense paid to third parties is due to the internalization of waste.

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 and continued modifications and upgrades at its facilities. In addition, the Company has an on-going strategic sourcing initiative in order to reduce operating costs by identifying suppliers that are able to supply goods and services at lower costs, by obtaining volume discounts where the Company is currently purchasing goods and services from various suppliers and consolidating these purchases with a small number of suppliers, and by reducing the internal costs of purchasing goods and services by reducing the number of suppliers that the Company uses through reducing the number of purchase orders that

must be prepared and invoices that must be processed. The acquisition of the CSD assets significantly increased the Company’s spending on purchased goods and services. 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 March 31, 2004 decreased $3.9 million to $23.2 million from $27.1 million for the comparable period in 2003. Technical Services selling, general and administrative expenses for the three months ended March 31, 2004 decreased $3.0 million to $11.4 million from $14.4 million for the comparable period in 2003 due to reduced headcount. Site Services selling, general and administrative expenses was flat for the three months ended March 31, 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 three months ended March 31, 2004 decreased $0.8 million to $7.6 million from $8.4 million for the comparable period in 2003. The decreases were primarily due to decreases in headcount, decreased professional fees, improved controls over expenses and decreased foreign currency transaction losses.

Accretion of Environmental Liabilities

Accretion of environmental liabilities for the three-month periods ended March 31, 2004 and 2003 was similar at $2.6 million and $2.7 million, respectively.

Depreciation and Amortization

Depreciation and amortization expense for the three months ended March 31, 2004 decreased $1.2 million to $5.4 million from $6.6 million for the comparable period in 2003. The decrease was primarily due to changes in estimates of the lives of the acquired CSD assets made subsequent to first quarter of 2003.

Restructuring

For the year ended December 31, 2002, the Company recorded a restructuring charge of $0.8 million related to the CSD assets acquisition. The restructuring charge consisted of $0.3 million for severance for individuals who were employees of the Company prior to the acquisition, and $0.5 million of costs associated with the decision to close sales offices and parts of facilities that were operated by the Company prior to the acquisition and that became duplicative. During the three months ended March 31, 2003, the Company revised its estimates of restructuring costs, resulting in a credit of $0.1 million.

Other Income (Expense)

As more fully described in the Note 7 in this Report on Form 10-Q, the Company issued Series C Preferred Stock for $25.0 million in September 2002. The Series C Preferred Stock is recorded on the Company’s financial statements as though it consisted of two components, namely (i) a non-convertible redeemable preferred stock which matures in seven years with a 6.0% annual dividend, and (ii) and an embedded derivative (the “Embedded Derivative”) which reflects the right of the holders of the Series C Preferred Stock to convert it into the Company’s common stock. For the quarter ended March 31, 2004, 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 at March 31, 2004. For the quarter ended March 31, 2004, the Company recorded other income of $5.3 million primarily because of the market price decline of the Company’s common stock that occurred during that quarter. The Company believes in future periods that the value of the Embedded Derivative could increase or decrease significantly based on such factors

as changes in the market value of the Company’s common stock, changes in prevailing interest rates, changes in the volatility of the Company’s common stock price and changes in strike price.

Interest Expense, Net

Interest expense, net of interest income for the three months ended March 31, 2004, decreased $0.1 million to $5.4 million from $5.5 million for the comparable period in 2003. The decrease in interest expense was due 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 the interest cost associated higher average balances outstanding for the three months ended March 31, 2004 as compared to the same period in 2003.

Income Taxes

Income tax expense for the three months ended March 31, 2004 increased $0.2 million to $1.2 million from $1.0 million for the comparable period in 2003. Income tax expense for the first quarter of 2004 consists primarily of current tax expense relating to the Canadian operations of $1.2 million and state income tax expense of $0.1 million relating to profitable operations in certain legal entities, partially offset by a federal tax benefit of $0.1 million relating to a fiscal 2000 alternative minimum tax carryback refund. Income tax expense for the first three months of 2003 consists primarily of current tax expense relating to the Canadian operations of $0.9 million and state income tax expense of $0.1 million relating to profitable operations in certain legal entities.

EBITDA Contribution

The combined EBITDA contribution by segments for the three months ended March 31, 2004 increased $3.4 million to $12.1 million from $8.7 million for the comparable period in 2003. The contribution of Technical Services decreased $0.2 million, which was more than offset by an increase in Site Services contribution of $3.3 million and a net decrease in Corporate Items cost of $0.3 million. The combined EBITDA contribution is comprised of revenues of $142.8 million and $142.3 million, net of cost of revenues of $107.5 million and $106.6 million and selling, general and administrative expenses of $23.2 million and $27.0 million for the three-month periods ended March 31, 2004 and 2003, respectively.

Liquidity and Capital Resources

Cash and Cash Equivalents

The Company’s primary sources of liquidity are cash flows from operations, existing cash and the Revolving Credit Facility (as hereinafter defined). For the three-month period ended March 31, 2004, net cash provided from operating activities was $6.1 million, and as of March 31, 2004, cash and cash equivalents were approximately $5.0 million, borrowing availability under the Revolving Credit Facility was $35.1 million and properties held for sale were $12.3 million.

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, we project that we will continue to meet our debt covenant requirements for each of the quarters ending June 30, 2004, September 30, 2004 and December 31, 2004. As part of the CSD acquisition, the Company assumed environmental liabilities of 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 three months ended March 31, 2004

For the three months ended March 31, 2004, the Company generated approximately $6.1 million of cash from operating activities. The Company recorded non-cash expenses during this period which provided sources of funds totaling $3.3 million. These adjustments consisted primarily of non-cash expenses of $5.4 million for depreciation and amortization and $2.6 million for the accretion of environmental liabilities, partially offset by a gain of $5.3 million resulting from the change in the value of the embedded derivative. Net sources of cash totaled $14.0 million. The largest of these other sources of cash was a $4.5 million reduction in accounts receivable due primarily to improved collections of accounts receivable and a $3.4 million reduction in unbilled accounts receivable due to the timing of sending invoices to customers. Other significant sources of cash were the net income for the quarter of $2.8 million and a reduction in income taxes payable of $1.8 million. Largely offsetting the sources of cash were uses of cash that totaled $11.2 million and consisted primarily of a reduction in accounts payable of $5.1 million, an increase in prepaid expenses of $2.8 million, and $3.0 million for environmental remedial and landfill liabilities that consisted of $1.8 million in spending and $1.2 of non-cash items.

For the three-month period ended March 31, 2004, the Company used $5.7 million of cash in investing activities. This consisted of additions to property, plant and equipment of $6.1 million and restricted investments purchased of $0.2 million to support the letters of credit issued relating to financial assurance for closure and post-closure obligations. These uses were partially offset by proceeds from the sale of fixed assets of $0.6 million.

For the three-month period ended March 31, 2004, the Company’s financing activities resulted in a net use of cash of $1.7 million. The primary uses of cash were to pay $0.8 million of financing costs incurred and to repay $0.6 in senior term loans.

Cash Flows for the three months ended March 31, 2003

For the three months ended March 31, 2003, the Company generated approximately $6.8 million of cash from operating activities. Non-cash expenses recorded for the period totaled $10.7 million. These adjustments consisted primarily of non-cash expenses of $6.6 million for depreciation and amortization, $2.7 million for the accretion of environmental liabilities and $0.5 million for the amortization of deferred financing costs. Other sources of cash totaled $20.8 million and consisted of a decrease in accounts receivable of $14.2 million which was largely due to a lower level of billings in the first quarter of 2003 as compared to the fourth quarter of 2002. Other significant sources of cash were decreases in unbilled accounts receivable and prepaid expenses of $2.6 million and $2.3 million, respectively. Other uses of cash totaled $17.5 million and consisted of a decrease in accounts payable of $5.1 million, a decrease in deferred revenue of $5.1 million and a decrease in accrued expenses of $3.3 million.

For the three-month period ended March 31, 2003, the Company used $8.5 million of cash in investing activities. This consisted of additions to property, plant and equipment of $8.5 million and restricted investments purchased of $0.2 million to support letters of credit issued relating to financial assurance for closure and post-closure obligations. These uses were partially offset by proceeds from the sale of fixed assets of $0.2 million.

Cash used in financing activities totaled $5.6 million for the three months ended March 31, 2003. Uses of cash from financing activities consisted primarily of payments of $0.4 million of Senior Loans, net repayments of $2.8 million on the Revolving Credit Facility and $2.3 million of uncashed checks.

Senior Loans and Subordinated Loans. The Senior and the Subordinated Loans were issued under a Financing Agreement dated September 6, 2002 (the “Financing Agreement”). As explained below, the Senior Loans now bear interest at LIBOR plus 7.75% and the Subordinated Loans now bear interest at 22.5% (of which up to one-half may be either paid in cash or in kind at the Company’s option). The Senior Loans and the Subordinated Loans are secured by a first security or mortgage interest in substantially all of the Company’s assets, except for the second security interests in the Company’s accounts receivable in which the Agent under the Revolving Credit Facility has a first security interest and the cash collateral provided by the Company to the issuer of letters of credit under the L/C Facility in which such issuer has a first security interest.

Financing Amendment required the Company to pay amendment fees totaling approximately $1.0 million in fiscal year 2003. In addition, even though the Company was in compliance with its loan covenants for the third and fourth quarters of 2003, in accordance with the Second Financing Amendment the Company paid an additional amendment fee of $0.6 million in April 2004 because the Company failed to achieve 95% of its projected consolidated EBITDA benchmark for the period commencing July 1, 2003 through December 31, 2003. The Second Financing Amendment increased the interest rates from those of the Financing Agreement for Senior and Subordinated Loans from LIBOR plus 7.25% to LIBOR plus 7.75% and from 22.0% to 22.5%, respectively. The Amendments to the Financing Agreement also prohibit the Company from paying dividends in cash on its Series B Preferred Stock and Series C Redeemable Preferred Stock, and prohibit the repurchase or retirement of outstanding common stock, preferred stock, warrants and stock options.

EBITDA for under the Financing Agreement, as amended, for the four consecutive quarter period ended March 31, 2004 is calculated as follows (dollars in thousands):


Net loss	$	(7,326	)
Accretion of environmental liabilities		10,969
Depreciation and amortization		25,239
Interest expense, net		23,572
Provision for income taxes		5,546
Non-recurring severance charges		996
Change in value of embedded derivative		(4,891	)

EBITDA	$	54,105

L/C Facility. At March 31, 2004, letters of credit outstanding under the L/C Facility were approximately $86.2 million.

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 are outstanding. Under the terms of the Series B Preferred Stock, the Company can elect to pay dividends in cash or in common stock with a market value equal to the amount of the dividend payable. The dividends due on January 15, 2003 were paid in cash. However, because of restrictions in the amendment to the Company’s Financing Agreement which became effective in May 2003, the Company issued 12,531 shares of the Company’s common stock in payment of the January 15, 2004 dividend requirement. The Company now anticipates that dividends on the Series B Preferred Stock will be paid in common stock for the foreseeable future.

New Accounting Pronouncements

In January 2003, the FASB issued FASB Interpretation No. 46 (“FIN 46”), “Consolidation of Variable Interest Entities.” FIN 46 requires that unconsolidated variable interest entities must be consolidated by their primary beneficiaries. A primary beneficiary is the party that absorbs a majority of the entity’s expected losses or residual benefits. 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 special purpose entities.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The Company is subject to market risk on the interest that it pays on its debt due to changes in the general level of interest rates. The Company’s philosophy in managing interest rate risk is to borrow at fixed rates for longer time horizons to finance non-current assets and to borrow at variable rates for working capital and other short-term needs. The following table provides information regarding the Company’s fixed rate borrowings at March 31, 2004 (dollars in thousands):


Scheduled Maturity Dates	Nine Months Remaining															Thereafter			Total
Scheduled Maturity Dates	2004			2005			2006			2007			2008			Thereafter			Total
Subordinated Loans	$	—		$	—		$	—		$	40,000		$	—		$	—		$	40,000
Redeemable Convertible Preferred Stock		—			—			—			—			—			36,673			36,673
Capital Lease Obligations		1,060			1,418			1,375			964			636			34			5,487

	$	1,060		$	1,418		$	1,375		$	40,964		$	636		$	36,707		$	82,160

Weighted average interest rate on fixed rate borrowings		15.2	%		15.3	%		15.2	%		14.0	%		6.0	%		6.0	%

In addition to the fixed rate borrowings described in the table above, the Company had at March 31, 2004 borrowings at variable interest rates of $106.6 million that bore interest at LIBOR (1.11% at March 31, 2004), plus 7.75% and borrowings of $35.2 million that bore interest at either the U.S. or Canadian “prime” rate (4.0% or 4.25% at March 31, 2004, respectively) plus 0.50%. The following table presents hypothetical situations of the amount of interest expense that would be incurred on an annual basis assuming the balance outstanding at March 31, 2004 remained unchanged and assuming three scenarios for interest rates: (i) interest rates remain unchanged from those on March 31, 2004, (ii) interest rates increase by 200 basis points and (iii) interest rates decrease by 200 basis points (dollars in thousands):


Description of Debt	Principal Balance March 31, 2004		Interest if Interest Rates Remain Unchanged		Interest if Interest Rates Increase 200 b.p.		Interest if Interest Rates Decrease 200 b.p.
Senior Loans	$	106,635	$	9,448	$	11,581	$	7,315
Revolving Credit Facility		35,153		1,590		2,293		887

	$	141,788	$	11,038	$	13,874	$	8,202

Historically, the Company has not entered into derivative or hedging transactions, nor has the Company entered into transactions to finance debt off of its balance sheet. The Company views its investment in the Canadian subsidiaries as long-term; thus, the Company has not entered into any hedging transactions between the Canadian dollar and the U.S. dollar. The Canadian subsidiaries transact approximately 30.6% of their business in U.S. dollars and any period end have cash on deposit in U.S. dollars and outstanding U.S. dollar accounts receivable related to these transactions. These cash and receivable accounts are subject to foreign currency transaction gains or losses. During the three-month-periods ended March 31, 2004 and 2003, the U.S. dollar fell approximately 1.2% and 7.0%, respectively, against the Canadian dollar resulting in foreign currency exchange losses of $0.1 million and $0.8 million, respectively. The average exchange rate for the quarter ended March 31, 2004 was 1.32 Canadian dollars to the U.S. dollar. Had the Canadian dollar been 10.0% stronger against the U.S. dollar, the Company would have reported increased net income by approximately $0.2 million. Had the Canadian dollar been 10.0% weaker against the U.S. dollar, the Company would have reported lower net income by approximately $0.2 million. The Company is subject to market risk arising from purchases of commodities, but these risks are minimal since no significant amount of commodities are used in the treatment of hazardous waste.

As more fully described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2003, the Company issued Series C Preferred Stock for $25.0 million in September 2002. The Series C Preferred

Stock is recorded on the Company’s financial statements as though it consisted of two components, namely (i) a non-convertible redeemable preferred stock which matures in seven years with a 6.0% annual dividend, and (ii) and an embedded derivative (the “Embedded Derivative”) which reflects the right of the holders of the Series C Preferred Stock to convert it into the Company’s common stock. The initial values of the two components were determined as of the issuance date based upon the relative fair values using a discounted cash flow model and an assumed rate of return of 14.0%. The Embedded Derivative was recorded in Other Long-term Liabilities at an initial fair value of $9.3 million and is periodically marked to market value until such time that the maximum number of shares of common stock which may be issued upon conversion is determined. As of March 31, 2004, the market value of the Embedded Derivative was determined to be $4.3 million and the Company recorded $5.3 million of Other Income during the first quarter of 2004 to reflect such adjustment. The closing price of the Company’s stock on March 31, 2004 was $7.41 per share. Had the stock price been $2.00 higher, the value of the Embedded Derivative would have been $10.8 million, and the Company would have recorded $1.2 million of Other Expense for the quarter ended March 31, 2004. Had the stock price $2.00 lower, the value of the Embedded Derivative would have been $0.2 million, and the Company would have recorded $4.1 million of additional Other Income for the quarter ended March 31, 2004.

Item 4. Controls and Procedures

Since the acquisition of the assets of the Chemical Services Division (the “CSD”) of Safety-Kleen Corp. (“Safety-Kleen”) effective September 7, 2002 (see Note 2 to the financial statements included in this report), the Company has focused upon integrating the operations acquired into the Company’s disclosure controls and procedures and internal controls. Safety-Kleen has publicly disclosed that it has historically had material deficiencies in many of its financial systems, processes and related internal controls. Due to the deficiencies in these systems and the Company’s belief that it will be able to utilize its own systems in order to improve the operations of the former CSD, the decision was made to integrate the United States operations of the former CSD into the Company’s business and financial reporting systems effective as of the acquisition date. As anticipated, the Company has experienced certain systems and efficiency issues during the initial period of the integration. The Company has made significant progress in integrating the CSD into the Company’s business and financial reporting systems and believes that all major systems for operations within the United States and certain systems in Canada are substantially integrated and efficiently operating as of March 31, 2004. During the integration process, the Company identified the need for various enhancements to address needs that are unique to the CSD business and to improve system efficiencies. In addition, the significant increase in transaction volume, as well as the significant increase in the number of new users of the Company’s systems, has increased the risk of human error or mistake during the integration period. Likewise, the acquisition and integration of a business much larger in size and scope of operations increases the risk that conditions may have been introduced that the Company’s design of its systems of control have not anticipated. Furthermore, Safety-Kleen’s preexisting deficiencies in financial systems, processes and related internal controls increased the risk that the historical unaudited financial statements of the CSD’s operations and cash flows which Safety-Kleen has provided to the Company were not accurate.

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

In October 2002, the Company established a Disclosure Committee pursuant to the provisions of the Sarbanes-Oxley Act. The Committee is chaired by the Company’s General Counsel and consists of the Company’s Chief Executive Officer, Chief Financial Officer, Corporate Controller, Senior Vice President of Risk Management and the vice president responsible for oversight of the environmental liabilities associated with discontinued facilities and operations. From time to time, the Committee also confers with two outside consultants, one an expert in investor relations and the other, an attorney specializing in Securities and Exchange Commission (the “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. 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 ensure that these internal control deficiencies do not lead to material misstatements in its Consolidated Financial Statements and to enable the completion of the audit of its Consolidated Financial Statements, notwithstanding the presence of the internal control weaknesses noted above.

The Company has addressed the material weaknesses noted, and believes it has implemented an improved process to properly document and calculate deferred revenue on a go forward basis. Furthermore, the Company believes that because of already implemented system and process enhancements, as well as improvements to existing controls and procedures that will be implemented and enforced by June 30, 2004, the reportable conditions will no longer be relevant as they relate to the Company’s internal control environment.

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. “Disclosure controls and procedures” are controls and procedures that are designed to ensure that information required to be disclosed by the Company in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that while the Company’s disclosure controls and procedures are substantially effective for these purposes as of March 31, 2004, the Company should continue its efforts to further improve its disclosure controls and procedures.

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