(Unaudited)

NOTE 1 Basis of Presentation

The consolidated interim financial statements included herein have been prepared by the Company, pursuant to the rules and regulations of the Securities and Exchange Commission, and include, in the opinion of management, all adjustments of a normal recurring nature necessary for the fair statement of results of interim periods. The operating results for the three months ended March 31, 2002 are not necessarily indicative of those to be expected for the full fiscal year. Reference is made to the audited consolidated financial statements and notes thereto included in the Company’s Report on Form 10-K for the year ended December 31, 2001 as filed with the Securities and Exchange Commission.

NOTE 2 Significant Accounting Policies

(a) New Accounting Pronouncements

In July 2001, the FASB issued SFAS No. 141, “Business Combinations” and SFAS No. 142, “Goodwill and Other Intangible Assets.” SFAS No. 141 requires that all business combinations be accounted for under the purchase method only and that certain acquired intangible assets in a business combination be recognized as assets apart from goodwill. SFAS No. 142 requires that ratable amortization of goodwill be replaced with periodic tests of the goodwill’s impairment and that intangible assets other than goodwill be amortized over their useful lives. SFAS No. 141 is effective for all business combinations initiated after June 30, 2001 and for all business combinations accounted for by the purchase method for which the date of acquisition is after June 30, 2001. The provisions of SFAS No.142 will be effective for fiscal years beginning after December 15, 2001, and was adopted by the Company, as required, in fiscal year 2002. The Company has historically accounted for acquisitions as purchases; thus, the adoption of SFAS No. 141 is not expected to materially affect the Company’s results. The Company has determined the adoption of SFAS No. 142 will eliminate amortization of goodwill expense of $767,000 in 2002. The Company tested goodwill for impairment as of December 31, 2001 using the criteria set forth under SFAS No. 142. Based on the results of the impairment test, the Company does not expect to record an impairment charge in 2002 relating to goodwill. See Note 3 for the effect of the implementation of SFAS No. 142 on the periods presented.

In July 2001, the FASB issued SFAS No. 143, “Accounting for Asset Retirement Obligations.” Statement No. 143 requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. When a liability is initially recorded, the entity capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement. The standard is effective for fiscal years beginning after June 15, 2002, with earlier application being encouraged. The Company is currently studying Statement No. 143, but the Company has not yet determined when the Statement will be adopted or the impact the Statement will have on results of operations or financial condition.

NOTE 2 Significant Accounting Policies (continued)

(a) New Accounting Pronouncements (continued)

In October 2001, the FASB issued SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” that replaces FASB Statement No. 121, “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of.” Statement No. 144 requires that those long-lived assets be measured at the lower of carrying amount or fair value less cost to sell, whether reported in continuing operations or in discontinued operations. Therefore, discontinued operations will no longer be measured at net realizable value or include operating losses that have not yet occurred. The provisions of Statement No. 144 are effective for financial statements issued for fiscal years beginning after December 15, 2001, with earlier application being encouraged. The Company adopted this statement in the first quarter of 2002. Statement No. 144 had no impact on results of operations or financial condition for the quarter ended March 31, 2002.

(b) Reclassifications

Certain reclassifications have been made in the prior periods’ consolidated financial statements to conform with the 2002 presentation.

NOTE 3 Goodwill Amortization

Effective January 1, 2002, the Company adopted SFAS No. 142, “Goodwill and Other Intangible Assets.” SFAS No. 142 requires that ratable amortization be replaced with periodic tests of the goodwill’s impairment. The following table shows the adjustment to net loss, and basic and diluted loss per share if the ratable amortization is excluded for the three months ended March 31, 2001 (in thousands except for per share amounts):

Long-term obligations	$	43,998	$	44,699

As described in the Form 10-K for the year ended December 31, 2001, the Company has a $51,000,000 Amended and Restated Loan Agreement (the “Amended Loan Agreement”) with a financial institution (the “Lender”). The Amended Loan Agreement includes a revolving credit facility (the “Revolver”). The Revolver allows the Company to borrow up to $30,000,000 in cash and letters of credit, based on a formula of eligible accounts receivable. At March 31, 2002, the Company had no borrowings under the Revolver. Letters of credit outstanding were $9,674,000 and funds available to borrow were approximately $16,358,000.

CLEAN HARBORS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 4 Financing Arrangements (continued)

The Amended Loan Agreement requires that the Company maintain $10,000,000 of working capital excluding the current portion of loans outstanding under the Amended Loan Agreement. The net worth covenant requires adjusted net worth, defined as net worth plus the balance owed on the Subordinated Notes (as described below) to be greater than $60,000,000. At March 31, 2002, the Company had $15,200,000 of working capital and $84,833,000 of adjusted net worth. The Amended Loan Agreement requires that the Company maintain on a rolling four quarter basis a minimum EBITDA of $20,000,000. For the four quarter period ended March 31, 2002 the Company reported EBITDA of $29,756,000. The Amended Loan Agreement also requires that the Company maintain a Senior Debt to EBITDA ratio of not more than 2.25 to 1.0. At March 31, 2002 the Senior Debt to EBITDA ratio was 0.58 to 1.0.

As described in the Form 10-K for the year ended December 31, 2001, the Company also has $35,000,000 of 16% Senior Subordinated Notes (the “Subordinated Notes”). The Subordinated Note Agreement contains covenants the most restrictive of which require that the Company maintain a rolling four quarter fixed charge coverage ratio of not less than 1.10 to 1.0. For the four quarters ended March 31, 2002, the fixed charge coverage ratio was 1.58 to 1.0. The Subordinated Notes require that the Company maintain a tangible capital base of not less than $35,500,000. At March 31, 2002, the tangible capital base was $55,555,000. The Company is required to maintain rolling four quarter earnings before interest, income taxes, depreciation and amortization (EBITDA) of not less than $18,000,000. For the four quarter period ended March 31, 2002, EBITDA was $29,756,000. The Company is also required to maintain a priority debt to EBITDA ratio calculated as of the last day of each fiscal quarter of not more than 2.25 to 1.0. Priority debt currently consists of debt issued under the Amended Loan Agreement. At March 31, 2002, the priority debt to EBITDA ratio was 0.26 to 1.0. The Company is required to maintain a ratio of total liabilities to tangible capital base of not more than 2.75 to 1.0. At March 31, 2002 the total liabilities to tangible capital base ratio was 0.97 to 1.0.

Also, as described in the Form 10-K for the year ended December 31, 2001, the Company has outstanding $9,700,000 of 10.75% Economic Development Revenue Bonds (the “Bond”). Under the Bond Documents, as amended, the Company may issue Bank Debt up to $35,000,000, provided that after the issuance the ratio of the Company’s total debt to total capital (debt plus stockholders’ equity) does not exceed 72.0% (which ratio will be reduced to 70.0% on January 1, 2006 and 65.0% on January 1, 2011). At March 31, 2002, the debt to capital ratio was 49.8%.

The Bonds, as amended, require the Company to maintain $750,000 in a debt service reserve fund held by the trustee for the benefit of the bondholders until the Bonds mature. The Company could be required to make additional payments to bring the total of the debt service reserve fund to a maximum of approximately $1,200,000 (including the $750,000 described above) if the EBITDA coverage ratio for any fiscal year is less than 1.25 to 1.0. The EBITDA coverage ratio for the year ended December 31, 2001 was 2.18 to 1.0, and the Company was therefore not required to make any such additional payments into the debt service reserve fund. The Company attained an EBITDA coverage ratio of 2.18 to 1.0 for the four quarters ended March 31, 2002.

NOTE 5 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. In the fourth quarter of 2000, based on the level of earnings for 2000 and management’s projections for profits in future years, it was determined that it was more likely than not that $2,400,000 of the net deferred tax assets would be utilized; and, in the fourth quarter of 2001, based on the level of earnings for 2001 and management’s projections for profits in future years, it was determined that it was more likely than not that all net operating loss carryforwards, with the exception of the net operating loss carryforwards relating to former ChemClear entities will be utilized. Accordingly, a tax benefit relating to the pre-tax loss has been recorded for the quarters ended March 31, 2002 and 2001.

NOTE 6 Loss Per Share (continued)

The Company has issued options, warrants and convertible preferred stock which are potentially dilutive to earnings. These have not been included in the above calculations, since their inclusion would have been antidilutive for the periods ended March 31, 2002 and 2001.

NOTE 7 Proposed Acquisition

On February 22, 2002, the Company signed an Acquisition Agreement to acquire the Chemical Services Division (“Division”) of Safety-Kleen Corp. (“Safety-Kleen”), which Agreement was amended on March 8, 2002 and April 30, 2002. Because Safety-Kleen and 73 of its domestic subsidiaries are operating under Chapter 11 of the Bankruptcy Code pursuant to a proceeding in the Bankruptcy Court for the District of Delaware, any sale of Safety-Kleen’s Chemical Services Division must comply with the Bankruptcy Code and be approved by the Bankruptcy Court. Accordingly, on February 22, 2002, Safety-Kleen submitted a Motion to the Bankruptcy Court to enter an order authorizing Safety-Kleen to sell the assets of the Division free and clear of all liens, claims, encumbrances and interests and assign leases and contracts either to the Company under the Acquisition Agreement or to a higher bidder. The following summarizes the principal terms of the Acquisition Agreement, as amended.

The Agreement provides that the Company will purchase the assets of the Chemical Services Division from Safety-Kleen for approximately $46,300,000 in cash and the assumption of certain environmental liabilities valued at approximately $265,000,000. The proposed acquisition will not include Safety-Kleen’s Pinewood Landfill located in South Carolina. The assets of the Chemical Services Division will include the stock of Safety-Kleen’s Canadian subsidiaries which are part of the division, which subsidiaries are not involved in Safety-Kleen’s bankruptcy proceeding. Because the Company will acquire the stock, rather than the assets of those Canadian subsidiaries, the Company will become subject to certain liabilities of those subsidiaries, but adjustments for those assumed liabilities will be made in the calculation on the closing date of the working capital of the Division as compared to a target amount of the Division’s working capital of $64,270,000. The purchase price for the acquisition will be adjusted either up or down based on the amount of working capital on the closing date as compared to the amount of the Division’s working capital at August 31, 2001. In addition, the Company and Safety-Kleen will each pay one-half of the pre-petition cure and reinstatement costs (“Cure Costs”) incurred prior to the closing relating to the assignment and assumption of those contracts and leases of the Division which the Company elects to assume until such Cure Costs equal $2,000,000. The Company will pay any Cure Costs under those assumed contracts and leases that exceed $2,000,000.

NOTE 7 Proposed Acquisition (continued)

The proposed acquisition is contingent upon satisfactory completion of due diligence, various regulatory approvals, obtaining adequate financing and approval of the Bankruptcy Court. In addition, the Acquisition Agreement calls for the Company and Safety-Kleen to enter into certain sales and disposal agreements which will become effective on the closing of the acquisition.

Bankruptcy rules require procedures that are most likely to maximize the realizable value of Safety-Kleen’s assets for the benefit of the debtor (Safety-Kleen) and its creditors. Accordingly, on March 8, 2002, the Bankruptcy Court approved bidding procedures which will allow financially qualified bidders to submit bids for Safety-Kleen’s Chemical Services Division. Under the approved bidding procedures, the Company is deemed to have submitted a qualified bid by entering into the Acquisition Agreement. Provided that the Acquisition Agreement has not been terminated in accordance with its terms by May 30, 2002, the Company will then make a $3,000,000 deposit, which will be returned if the Company is not the successful bidder for the Division or the acquisition does not close for any reason other than a default by the Company of its obligations under the Agreement. If any other qualified bidder elects to submit a bid for all or a portion of the assets of the Division, such bidder must make a minimum $3,000,000 deposit by no later than May 30, 2002 and submit a written bid which (together with other qualified bids if such bid is for only a portion of the Division’s assets) the Board of Directors of Safety-Kleen determines in good faith is not materially more burdensome or conditional than the terms under the Acquisition Agreement and which is greater than $53,520,000 plus the assumption of the approximately $265,000,000 of certain environmental liabilities. Any subsequent qualified bids must be greater than the last qualified bid by $1,000,000. The bid deadline is May 30, 2002. If any qualified bid other than the bid which has been submitted by the Company is received, an auction will be held where all qualified bidders will have the opportunity to submit additional bids. The Bankruptcy Court has scheduled for June 13, 2002 a hearing to approve the sale of the Chemical Services Division to the highest bidder under the approved bidding procedures. If the Company is the successful bidder, the Company now anticipates the closing will occur during the third quarter of 2002.

NOTE 7 Proposed Acquisition (continued)

Provided that the acquisition does not close and the Company is not in default of any provision of the Agreement for which Safety-Kleen has notified the Company, Safety-Kleen will be required to reimburse the Company’s reasonable, documented, out-of-pocket costs in amounts ranging from $1,500,000 to $5,250,000 depending on the stage and circumstances under which the Agreement is terminated or abandoned. Furthermore, if Safety-Kleen sells the Chemical Services Division to a higher bidder, the Company will be entitled to a termination fee of either $3,500,000 or $7,000,000 depending on whether Safety-Kleen sells the Division to such other bidder prior to or after the Company receives its financing commitment. In no event, however, will the Company be entitled to receive both the termination fee and expense reimbursement. Through March 31, 2002, the Company had capitalized to prepaid expenses $1,717,000 of acquisition costs relating to the proposed acquisition of the Chemical Services Division from Safety-Kleen.

RESULTS OF OPERATIONS (continued)

REVENUES

Revenues for the first quarter of 2002 were $53,319,000 up $1,501,000 or 2.9% compared to revenues of $51,818,000 for 2001. Site services accounted for all of the increase; technical services were flat. The Company performed one large site services job in each first quarter. The job performed in 2002 related to the events of September 11 and was larger than the job performed in 2001. In addition, approximately 1.2% of the 2.9% increase in revenues was due to favorable developments in the resolution of certain contract issues which benefited both revenues and gross margin. The Company believes that these revenue increases were partially offset by lower other site services work performed due to the general economic environment and response to fewer weather related transportation accidents due to the mild and dry winter. Within technical services, CleanPack revenues increased due to an increase in base business. Partially offsetting the increase in CleanPack revenues were decreases in transportation and disposal revenues due to a large job in 2001 for which no similar sized job was performed in 2002. Volumes processed through the plants increased 6.4%. Pricing of waste processed decreased 3.0%

There are many factors which have impacted, and continue to impact, the Company’s revenues. These factors include: 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 over capacity; and direct shipment by generators of waste to the ultimate treatment or disposal location.

COST OF REVENUES

Cost of revenues for the first quarter of 2002 was $38,942,000 compared to $38,451,000 for the first quarter of 2001, an increase of $491,000. As a percentage of revenues, cost of revenues decreased from 74.2% for the first quarter of 2001 to 73.0% for the first quarter of 2002. One of the largest components of cost of revenues is the cost of sending waste to other companies for disposal. Disposal costs paid to third parties as a percentage of revenues increased from 8.1% for the first quarter of 2001 to 10.9% for the first quarter of 2002. This increase in disposal expense is due to an increase in wastes sent directly to outside disposal vendors from customer sites, and an increase in volume and change in mix of waste processed through the Company’s facilities. Other costs of revenues decreased from 66.1% for the quarter ended March 31, 2001 to 62.1% for the quarter ended March 31, 2002. This decrease was primarily caused by the increase in waste processed through the plants and the fixed cost nature of the plants.

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 during the first quarter 1999, the Company commenced a 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. No assurance can be given that the Company’s efforts to manage future operating expenses will be successful. Efforts to reduce costs are ongoing.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

Selling, general and administrative expenses increased from $9,780,000 for the quarter ended March 31, 2001 to $10,090,000 for the quarter ended March 31, 2002, an increase of $310,000 or 3.2%. The increase was primarily due to increased health insurance claims for the Company’s largely self-insured plan, and increases in salaries and wages in order to remain competitive in the markets in which the Company operates. Partially offsetting these increases were decreases in travel expenses due to cost containment measures taken in response to the current soft economic environment and a decrease in professional fees which was largely due to decreased legal fees due to the settlement in the last half of 2001 of two legal matters.

DEPRECIATION AND AMORTIZATION

Depreciation and amortization expense decreased from $2,789,000 for the quarter ended March 31, 2001 to $2,695,000 for the quarter ended March 31, 2002, a decrease of $94,000 or 3.4%. Amortization of goodwill for the first quarter of 2001 was $191,000, while no amortization of goodwill was recorded for the quarter ended March 31, 2002 due to the adoption of SFAS No. 142 “Goodwill and Other Intangible Assets” as of January 1, 2002. SFAS No. 142 requires that ratable amortization of goodwill be replaced with periodic tests of the goodwill’s impairment. Partially offsetting the decrease in amortization relating to goodwill was a net increase in depreciation of fixed assets and other intangibles of $97,000 due to net additions.

INTEREST EXPENSE, NET

Interest expense net of interest income was $2,114,000 for the first quarter of 2002 as compared to $2,128,000 for the first quarter of 2001. The slight decrease in interest expense was due to lower average balances owed in the first quarter of 2002 as compared to the first quarter of 2001 being largely offset by higher average interest rates for the first quarter of 2002 as compared to the first quarter of 2001.

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. In the fourth quarter of 2000, based on the level of earnings for 2000 and management’s projections for profits in future years, it was determined that it was more likely than not that $2,400,000 of the net deferred tax assets would be utilized; and, in the fourth quarter of 2001, based on the level of earnings for 2001 and management’s projections for profits in future years, it was determined that it was more likely than not that all net operating loss carryforwards, with the exception of the net operating loss carryforwards relating to former ChemClear entities, will be utilized. Accordingly, a tax benefit relating to the pre-tax loss has been recorded for the quarters ended March 31, 2002 and 2001.

PROPOSED ACQUISITION

The Agreement provides that the Company will purchase the assets of the Chemical Services Division from Safety-Kleen for approximately $46,300,000 in cash and the assumption of certain environmental liabilities valued at approximately $265,000,000. The proposed acquisition will not include Safety-Kleen’s Pinewood Landfill located in South Carolina. The assets of the Chemical Services Division will include the stock of Safety-Kleen’s Canadian subsidiaries which are part of the Division, which subsidiaries are not involved in Safety-Kleen’s bankruptcy proceeding. Because the Company will acquire the stock, rather than the assets of those Canadian subsidiaries, the Company will become subject to certain liabilities of those subsidiaries, but adjustments for those assumed liabilities will be made in the calculation on the closing date of the working capital of the Division. The purchase price for the acquisition will be adjusted either up or down based on the amount of working capital on the closing date as compared to the target amount of the Division’s working capital of $64,270,000. In addition, the Company and Safety-Kleen will each pay one-half of the pre-petition cure and reinstatement costs (“Cure Costs”) incurred prior to the closing relating to the assignment and assumption of those contracts and leases of the Division which the Company elects to assume until such Cure Costs equal $2,000,000. The Company will pay any Cure Costs under those assumed contracts and leases that exceed $2,000,000.

FACTORS THAT MAY AFFECT FUTURE RESULTS

Factors Associated with the Proposed Acquisition

On February 22, 2002, the Company signed an Acquisition Agreement to acquire the Chemical Services Division of Safety-Kleen. If the proposed acquisition is completed, the acquisition will make the Company the largest operator of hazardous waste disposal facilities in North America with annualized revenue of approximately $750,000,000. While the Company believes that the proposed acquisition has the potential to generate significant value for shareholders, the proposed acquisition also presents certain risks.

If the proposed acquisition is successfully completed, the Company now anticipates it will incur out-of-pocket costs in excess of $10,000,000 relating to due diligence investigations, consulting fees associated with the proposed integration of the Division into the Company’s business and financial reporting systems, financing and financial assurance commitments, and investment banking, legal and accounting fees and expenses associated with the acquisition and the related refinancing of the Company’s outstanding debt. If the acquisition does not close, the Company may nevertheless incur a substantial portion of those expenses, depending upon the stage and the circumstances under which the Acquisition Agreement is terminated or abandoned. Provided the acquisition does not close and the Company is not in default of any provision of the Agreement, Safety-Kleen will be required to pay to the Company either expense reimbursement or a termination fee in certain specified amounts as described above under “Proposed Acquisition.” However, such expense reimbursement or termination fee may not be sufficient to reimburse the Company for all of the expenses which the Company will incur if the acquisition does not close.

Safety-Kleen has publicly disclosed that it has material deficiencies in many of its financial systems, processes and related internal controls. If the acquisition is completed, the Company believes that it will be able to utilize its systems to improve the operations of the Chemical Services Division, and the Company and its management consultants are now actively preparing for integration of the Division into the Company’s business and financial reporting systems effective as of the closing. However, if any significant delay should occur in such integration, such delay could have a material adverse affect on the results of operations and cash flows for the combined companies. Furthermore, Safety-Kleen’s deficiencies in financial systems, processes and related internal controls increase the risk that the unaudited financial statements of the Division’s operations and cash flows which Safety-Kleen has provided to the Company are not accurate. The Company and its advisors are now conducting due diligence investigations with respect to the operations and cash flows of the Division.

CONDITION AND RESULTS OF OPERATIONS

FACTORS THAT MAY AFFECT FUTURE RESULTS (CONTINUED)

Factors Associated with the Proposed Acquisition, (continued)

The proposed integration of Safety-Kleen’s Chemical Services Division into the Company will require significant effort by key employees of both the Company and the Division. Accordingly, if the Company were not able to retain key employees of the Division and the Company during the integration period, this could adversely affect such integration and therefore operations and cash flows.

As part of the proposed acquisition, the Company will assume approximately $265,000,000 of environmental liabilities, as such liabilities are calculated on a present value basis in accordance with generally accepted accounting principles (which take into consideration both the amount of such liabilities and the timing when it is projected that the Company will be required to pay such liabilities). The Company is now performing due diligence investigations with respect to both the amount and timing of such liabilities. The Company now anticipates such liabilities will be payable over many years and that cash flow generated 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.

After the Company closes the acquisition of any significant business, the rules of the Securities and Exchange Commission (the “SEC”) require the Company to file as part of the Company’s periodic reports and registration statements for securities offerings audited financial statements for the acquired business. As previously noted, Safety-Kleen has publicly disclosed that it has material deficiencies in many of its financial systems, processes and related internal controls. Safety-Kleen has provided the Company audited balance sheets for the Chemical Services Division as of the end of each of the Division’s three most recently completed fiscal years, but due to Safety-Kleen’s deficiencies, Safety-Kleen’s auditors have advised Safety-Kleen that they will not be able to provide auditors’ reports with respect to the Division’s statements of operations and cash flows for such three fiscal years. The Company has received a “no-action letter” from the SEC staff with respect to the periodic reports which the Company will file following the closing. However, until the Company is able to obtain and file audited statements of operations and cash flows of the Division (on a separate basis for any relevant periods prior to the closing and on a combined basis with the Company for periods following the closing) for at least three years (or such lesser period as the SEC staff may permit in the future), the Company will not be able to file registration statements for public securities offerings by the Company (except for offerings involving employee benefit plans and secondary offerings by holders of warrants and other securities in the Company). This could prevent the Company from being able to access the public capital markets for a period of up to three years following the closing, but it would not prevent the Company from obtaining financing through other sources such as private equity or debt placements and bank loans.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

FACTORS THAT MAY AFFECT FUTURE RESULTS (CONTINUED)

Factors Associated with the Proposed Acquisition, (continued)

The Company and Safety-Kleen’s Chemical Services Division provide services to certain customers which use both companies in order to ensure competitive pricing and reduce the risk that either company will not be able to perform all of the services required by such customers. If the proposed acquisition is completed, a portion of those customers may seek to place some business with other vendors so that such customers can continue to maintain more than one source of supply for environmental services. This could cause the results from operations and cash flows of the combined companies to be less than anticipated based upon the prior separate operations of the Company and the Division.

If the proposed acquisition is completed, the Company will have a high ratio of total liabilities (including the present value of the assumed environmental liabilities calculated as described above) to stockholders’ equity. This high ratio will increase the risk that unexpected events could have a materially adverse affect on the Company’s financial condition.

Other Factors

The Company’s future operating results may be affected by a number of factors, including the Company’s ability to: utilize its facilities and workforce profitably in the face of intense price competition; maintain or increase market share in an industry which appears to be downsizing and consolidating; realize benefits from cost reduction programs; generate incremental volumes of waste to be handled through its facilities from existing sales offices and service centers; obtain sufficient volumes of waste at prices which produce revenue sufficient to offset the operating costs of the facilities; minimize downtime and disruptions of operations; and develop the industrial services business.

The future operating results of the Company’s incinerator may be affected by factors such as its ability to: obtain sufficient volumes of waste at prices which produce revenue sufficient to offset the operating costs of the facility; minimize downtime and disruptions of operations; and compete successfully against other incinerators which have an established share of the incineration market.

CLEAN HARBORS, INC. AND SUBSIDIARIES

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

FACTORS THAT MAY AFFECT FUTURE RESULTS (CONTINUED)

Other Factors, (continued)

The Company’s operations may be affected by the commencement and completion of major site remediation projects; cleanup of major spills or other events; seasonal fluctuations due to weather and budgetary cycles influencing the timing of customers’ spending for remedial activities; the timing of regulatory decisions relating to hazardous waste management projects; changes in regulations governing the management of hazardous waste; secular changes in the waste processing industry towards waste minimization and the propensity for delays in the remedial market; suspension of governmental permits; and fines and penalties for noncompliance with the myriad of regulations governing the Company’s diverse operations. As a result of these factors, the Company’s revenue and income could vary significantly from quarter to quarter, and past financial performance should not be considered a reliable indicator of future performance.

Typically during the first quarter of each calendar year there is less demand for environmental remediation due to the cold weather, particularly in the Northeast and Midwest regions, and increased possibility of unplanned weather related plant shutdowns.

FINANCIAL CONDITION AND LIQUIDITY

For the quarter ended March 31, 2002, net cash used by operations was $954,000. Cash used in operations totaled $14,183,000 and consisted primarily of reductions in accounts payable of $4,766,000, accrued disposal costs of $1,427,000, deferred revenue of $2,122,000 and other accrued expenses of $3,164,000. Accounts payable and accrued disposal costs decreased due to the lower level of business activity in the first quarter of 2002 as compared to the fourth quarter of 2001. Deferred revenue decreased due to lower levels of waste on hand at March 31, 2002 as compared to December 31, 2001. Other accrued expenses decreased largely due to the payment of incentive bonuses relating to 2001 in the first quarter of 2002. The other significant use of cash was due to a $1,890,000 increase in prepaid expenses of which $1,549,000 of the increase was acquisition costs relating to the proposed acquisition of the Chemical Services Division from Safety-Kleen Corp. Sources of cash from operations totaled $13,229,000 and consisted primarily of a $10,039,000 reduction in accounts receivable due to lower levels of business activity in the first quarter of 2002 as compared to the fourth quarter of 2001 and $2,695,000 of non-cash expenses for depreciation and amortization.

Cash used in investing activities for the first quarter of 2002 totaled $2,102,000 and consisted primarily of additions to property plant and equipment of $2,118,000.

FINANCIAL CONDITION AND LIQUIDITY (CONTINUED)

Cash used in financing activities totaled $1,076,000. Uses of cash in financing activities totaled $1,435,000 and consisted of payments on long-term obligations of $929,000, a reduction of uncashed checks relating to the Company’s cash management program of $394,000 and preferred stock dividends of $112,000. Partially offsetting the uses of cash in financing activities were sources of cash from financing activities which totaled $359,000 and consisted almost entirely of cash proceeds from the exercise of stock options of $304,000 and from the employee stock purchase plan of $52,000.

The Company used $4,132,000 of the $6,715,000 of cash on hand at December 31, 2001 in order to fund the cash used in operations of $954,000, fund the cash used in investing activities of $2,102,000 and fund the cash used in financing activities of $1,076,000.

For the quarter ended March 31, 2001, net cash used by operations was $1,270,000. Cash used in operating activities totaled $7,778,000 and consisted primarily of a $3,825,000 reduction in accounts payable, the loss for the quarter of $1,032,000 and a decease in deferred revenue of $1,805,000. The reduction in accounts payable was primarily due to the reduced levels of business activity in the first quarter of 2001 as compared to the fourth quarter of 2000, and the decrease in deferred revenue was due the reduction in the volume of waste to be disposed of that had accumulated at December 31, 2000 due to inclement weather which delayed the Company’s ability to ship the waste to the ultimate disposal facility. Partially offsetting the cash used in operations was cash generated from operations of $6,508,000 which consisted primarily of non-cash expenses for depreciation and amortization of $2,789,000 and a reduction in accounts receivables of $2,307,000 which was due to the reduced levels of business activity in the first quarter of 2001 as compared to the fourth quarter of 2000.

In addition, the Company used $821,000 of cash in investing activities which consisted primarily of $815,000 used to purchase property, plant and equipment. The Company used $550,000 to make payments under the term notes and paid $582,000 in refinancing costs through March 31, 2001. The primary sources of funds for the cash requirements previously discussed were borrowings of $1,253,000 under the revolving credit facility and reducing cash on hand by $1,901,000.

Also, as described in the Form 10-K for the year ended December 31, 2001, the Company has outstanding $9,700,000 of 10.75% Economic Development Revenue Bonds (the “Bonds”). Under the Bond Documents, as amended, the Company may issue Bank Debt up to $35,000,000, provided that after the issuance the ratio of the Company’s total debt to total capital (debt plus stockholders’ equity) does not exceed 72.0% (which ratio will be reduced to 70.0% on January 1, 2006 and 65.0% on January 1, 2011). At March 31, 2002, the debt to capital ratio was 49.8%.

The Bonds, as amended, require the Company to maintain $750,000 in a debt service reserve fund held by the trustee for the benefit of the bondholders until the Bonds mature. The Company could be required to make additional payments to bring the total of the debt service reserve fund to a maximum of approximately $1,200,000 (including the $750,000 described above) if the EBITDA coverage ratio for any fiscal year is less than 1.25 to 1.0. The EBITDA coverage ratio for the year ended December 31, 2001 was 2.18 to 1.0 and the Company was therefore not required to make any such additional payments into the debt service reserve fund. The Company attained an EBITDA coverage ratio of 2.18 to 1.0 for the four quarters ended March 31, 2002.

FINANCIAL CONDITION AND LIQUIDITY (CONTINUED)

Excluding capital expenditures that may be required if the proposed acquisition of Safety-Kleen’s Chemical Services Division is consummated, the Company expects 2002 capital expenditures to be approximately $8,000,000. Capital expenditures are expected to be limited to maintaining existing capital assets, replacing site services equipment, upgrading information technology hardware and software, and specific strategic initiatives.

The Company believes that cash generated from operations in the future together with availability under its Revolver will be sufficient to operate the business and fund capital expenditures. Excluding the effect of the proposed acquisition of Safety-Kleen’s Chemical Services Division, the Company believes that interest expense in 2002 will be somewhat lower than in 2001 with the decrease in interest expense due to lower average debt outstanding.

Dividends on the Company’s Series B Convertible Preferred Stock are payable on the 15th day of January, April, July and October, at the rate of $1.00 per share, per quarter; 112,000 shares are outstanding. Under the terms of the preferred stock, the Company can elect to pay dividends in cash or in common stock with a market value equal to the amount of the dividend payable. The Company was required to pay the January 15, 2001 dividend in common stock due to restrictions under its loan agreements for which the Company issued 59,438 shares of common stock to the holders of the preferred stock in the period ended March 31, 2001. The Company paid the dividend for the period ended March 31, 2002 in cash, and the Company anticipates that the preferred stock dividends will be paid in cash for the foreseeable future.

Exhibit 2.3

SECOND AMENDMENT TO ACQUISITION AGREEMENT

WHEREAS, Safety-Kleen Services, Inc. (the “Seller”) and Clean Harbors, Inc. (the “Purchaser”), are parties to an Acquisition Agreement dated as of February 22, 2002, as amended by the First Amendment to Acquisition Agreement dated as of March 8, 2002 (as so amended, the “Acquisition Agreement”);

WHEREAS, the Seller and the Purchaser wish to amend certain provisions of the Acquisition Agreement as set forth in this Second Amendment to Acquisition Agreement (this “Amendment”);

NOW, THEREFORE, the parties hereto agree as follows:

1. Section 1.1(b)(ii)(A) of the Acquisition Agreement is hereby amended by changing the words “prior to the Due Diligence Expiration Date” which appears in such Section to “on or prior to the Purchaser Schedule Delivery Date,” (ii) Sections 1.1(b)(ii)(B) and (D) of the Acquisition Agreement are hereby amended by changing the words “prior to the Due Diligence Expiration Date” to “on or prior to May 10, 2002,” and (iii) Section 1.1(b)(vi)(B) of the Acquisition Agreement is hereby amended by changing the words “(which Schedule will be provided by the Seller prior to the Due Diligence Expiration Date)” to read as follows: “(which Schedule will be provided by the Purchaser on or prior to May 10, 2002, provided that, to the extent that the Purchaser shall elect to delete from Schedule 1.1(b)(vi)(B) any Real Property Leases which appear on the schedule of all existing Real Property Leases of the Seller and the Selling Subs which was delivered by the Seller to the Purchaser on April 8, 2002, the Purchaser shall remain liable for any Assumed Liabilities associated with the leased properties subject to such deleted Real Property Leases (other than obligations in respect of rent and tax and utility payments which would have arisen for periods after the Closing and any Cure Costs which would have been payable under Section 1.4 in connection with such deleted Real Property Leases) to the same extent as the Purchaser would have been liable had such deleted Real Property Leases been included on Schedule 1.1(b)(vi)(B) as delivered by the Purchaser).

2. Section 1.1 of the Acquisition Agreement is hereby amended by adding a new Section 1.1(e) reading as follows:

(e) Although the Purchaser shall endeavor to use its reasonable best efforts to include within Schedules 1.1(b)(ii)(B) and (D) and Schedule 1.1(b)(vi)(B) all of those contracts and Real Property Leases which the Purchaser has identified through May 10, 2002 as includable within the Assigned Contracts and Leases, the Purchaser shall retain the right to add additional contracts and Real Property Leases through the Purchaser Schedule Delivery Date. Nothing in this Section 1.1(e) shall affect the respective rights and obligations of the Purchaser and the Seller with respect to executory contracts or unexpired leases with respect to the Business under Section 5.12 of this Agreement.

3. Section 1.1(b)(v) of the Acquisition Agreement is hereby amended to read as follows:

(v) all rights and claims under all warranties, representations and guarantees made by suppliers, manufacturers and contractors in connection with the Acquired Assets and all rights and claims relating to Assumed Liabilities except those shown or described on Schedule 1.1(b)(v) provided that, notwithstanding any other provision of this Agreement or any Schedule to the contrary, the Acquired Assets shall include rights and claims under insurance policies (if any) held by the Seller or any of its Affiliates as of the Closing which are applicable to liabilities and obligations under Environmental Laws (or other Laws) that relate to violations of Environmental Laws arising before the Closing Date in connection with the Owned Real Property, the real property subject to Real Property Leases, the real property owned or leased, directly or indirectly, by any Transferred Sub, or the operation of the Business which are assumed by the Purchaser, but only to the extent that (A) such insurance policies are not either (i) general liability insurance policies issued prior to 1987 without pollution exclusions or (ii) part of the Financial Assurance provided by the Seller or its Affiliates under applicable Environmental Laws, and (B) such assignment of rights and claims can be accomplished without additional cost to the Seller or any of its Affiliates or other adverse consequence (which shall be deemed to include, without limitation, any potential or actual reduction of payments for other liabilities covered by such policies because of maximum coverage limits) to the Seller or any of its Affiliates under such insurance policies (if any);

4. Section 1.4 of the Acquisition Agreement is hereby amended in order to limit to One Million Dollars ($1,000,000) the Seller’s maximum obligation to pay Cure Costs by deleting the first two sentences of Section 1.4 and inserting in place thereof the following sentence: “The Seller and the Purchaser shall each pay one-half of any and all pre-petition cure and reinstatement costs or expenses (“Cure Costs”) incurred prior the Closing Date, of or relating to the assumption and assignment pursuant to this Agreement of the Assigned Contracts and Leases until such costs and expenses equal Two Million Dollars ($2,000,000) (the “Cure Costs Cap”).

5. Section 1.8 of the Acquisition Agreement is hereby amended to read as follows:

Section 1.8. Allocation of Purchase Price for Tax Purposes. The Seller and the Purchaser agree that, for all tax reporting purposes, the allocation of the Cash Purchase Price and the Assumed Liabilities to the Acquired Assets shall be as set forth on Schedule 1.8, which Schedule 1.8 shall be completed by the Closing Date and which, when completed, will have been arrived at by arm’s length negotiation in compliance with Section 1060 of the Internal Revenue Code of 1986, as amended. In their preparation of Schedule 1.8, the Seller and the Purchaser will use their best efforts to value the Assumed Liabilities (including, in particular, the Assumed Liabilities associated with compliance with Environmental Laws included therein) as of the Closing Date in accordance with the most recent estimates of the amount and timing of such Liabilities then available to the Purchaser and the Seller. If there is any adjustment to the Unadjusted Cash Purchase Price or the Assumed Liabilities in accordance with this Agreement, the Seller and the Purchase agree to make appropriate adjustments to the allocation set forth in Schedule 1.8. Each of the Purchaser and the Seller shall (i) timely file all forms (including Internal Revenue Service Form 8594) and Tax Returns required to be filed in connection with such allocation, (ii) be bound by such allocation for purposes of determining Taxes, (iii) prepare and file, or cause to be prepared and filed, its Tax Returns on a basis consistent with such allocation and (iv) take no position, or cause no position to be taken, inconsistent with such allocation on any applicable Tax Return, in any audit or proceeding before any Tax Authority or in any report made for Tax purposes. However, nothing in this Section 1.8 shall be deemed to prohibit the Purchaser, for financial reporting purposes, from making adjustments to the Purchase Price as determined for tax purposes in order to reflect the costs incurred by the Purchaser in connection with this transaction and, if in the reasonable judgment of the Purchaser and its independent public accountants, additional adjustments are necessary or appropriate based upon GAAP and the most recent estimates then available to the Purchaser as to the amount and timing of the Assumed Liabilities associated with compliance with Environmental Laws being assumed by the Purchaser in connection with this transaction. If the allocation set forth on Schedule 1.8 is disputed by any Taxing Authority, the party receiving notice of such dispute shall promptly notify the other party hereto concerning the existence and resolution of such dispute.

6. Sections 2.2(a)(vi), (viii) and (ix) of the Acquisition Agreement are hereby amended to change the words “within fifty (50) days after the date of this Agreement” to “by May 24, 2002.”

7. Section 2.2(a)(xiii) of the Acquisition Agreement is hereby amended to read as follows:

(xiii) certificates of tax and legal good standing (to the extent applicable in the Transferred Subs’ jurisdiction of organization) and releases from secured lenders and other third parties evidencing that the non-domestic Transferred Subs are in good standing (if appropriate) and that the secured lenders of the non-domestic Transferred Subs and such other third parties have released their security interests and other claims (other than claims which are either (A) liabilities which have been deducted in the calculation of Working Capital under Section 1.7(b) or (B) liabilities or obligations arising under applicable Environmental Laws (or other Laws) that relate to violations of Environmental Laws) on the assets of such Transferred Subs and on the issued and outstanding equity interests of such Transferred Subs;

8. Section 6.1(a) of the Acquisition Agreement is hereby amended to change the date therein from “June 20, 2002” to “June 27, 2002.”

9. Article IX of the Acquisition Agreement is hereby amended to (i) revise the definitions of “Affiliate” and “Assigned Contracts and Leases,” (ii) correct the typographical error that now appears in the definition of “Target Working Capital,” and (iii) add a definition for “Purchaser Schedule Delivery Date” as follows:

“Affiliate” of a Person means any other Person that, directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common control with, the first mentioned Person. In no event shall Laidlaw Inc. or any of its direct or indirect subsidiaries be deemed an Affiliate of Safety-Kleen Corp. or any of its direct or indirect subsidiaries.

“Assigned Contracts and Leases” means those contracts and Real Property Leases listed on Schedules 1.1(b)(ii)(A), (B) and (D) and Schedule 1.1(b)(vi)(B), provided that the Seller will not be deemed to have failed to satisfy its obligation to include within the Assigned Contracts and Leases transferred at the Closing as part of the Acquired Assets any Assigned Contract or Lease which is listed on Schedules 1.1(b)(ii)(A), (B) and (D) and Schedule 1.1(b)(vi)(B) as of the Purchaser Schedule Delivery Date but which, in the case of Schedules 1.1((b)(ii)(B) and (D) and Schedule 1.1(b)(vi)(B), was not listed on such Schedules delivered pursuant to Section 1.1(e) by the Purchaser to the Seller by May 10, 2002, if the Seller shall have used its reasonable best efforts to cause such Assigned Contract or Lease to be part of the Acquired Assets.

“Purchaser Schedule Delivery Date” means thirty (30) days following the issuance of the Section 363/365 Order.

“Target Working Capital” means Sixty-four Million, Two Hundred and Seventy Thousand Dollars ($64,270,000).

10. To the extent that the Seller reasonably determines that the entities listed below do not have liabilities and claims asserted against them which are Assumed Liabilities (as such term is defined in the Acquisition Agreement) and do not conduct operations which are part of the Business (as such term is defined in the Acquisition Agreement), Schedule 9.1 to the Acquisition Agreement as previously delivered by the Seller to the Purchaser will be amended to delete from that Schedule and therefore from the Selling Subs the following entities: USPCI of Mississippi, Inc.; Safety-Kleen (Delaware), Inc.; SK Services (East), L.C.; SK Services, L.C.; Safety-Kleen (Rosemount), Inc.; Safety-Kleen OSCO Holdings, Inc.; Safety-Kleen (Nashville), Inc.; and OSCO Treatment Systems of Mississippi, Inc.

11. Except as described in the preceding sections of this Amendment, the Acquisition Agreement shall remain in full force and effect.

IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of April 30, 2002.
