PURCHASE AND SALE AGREEMENT (the “Agreement”), dated as of May 3, 2006, by and between SITA U.S.A., Inc., a Delaware corporation (“Seller”), and Clean Harbors, Inc., a Massachusetts corporation (“Buyer”).

RECITALS

WHEREAS, Seller owns all of the outstanding membership interests (the “Membership Interests”) in Teris L.L.C., a Delaware limited liability company (the “Company”);

WHEREAS, Seller desires to sell to Buyer, and Buyer desires to purchase from Seller, all of the Membership Interests in the Company outstanding on the Closing Date (as defined in Section 2.1 hereof) upon the terms and subject to the conditions set forth herein;

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants, agreements, undertakings and obligations set forth herein, and intending to be legally bound hereby, the parties hereto agree as follows (with certain terms having the respective meanings set forth in Section 10.14 hereof and Exhibit 1.2 hereto):

ARTICLE I
SALE AND PURCHASE OF MEMBERSHIP INTERESTS

SECTION 1.1 Sale and Purchase of Membership Interests. Upon the terms and subject to the conditions set forth in this Agreement and on the basis of the representations, warranties, covenants, agreements, undertakings and obligations contained herein, at the Closing, Seller hereby agrees to sell to Buyer, and Buyer hereby agrees to purchase from Seller, all of the Membership Interests, free and clear of any and all Liens, for the consideration specified in this Article I.

SECTION 1.2 Purchase Price. The purchase price for the Membership Interests shall be an amount equal to the Purchase Price, as calculated in accordance with Exhibit 1.2. Buyer shall pay to Seller at the Closing the Closing Payment by delivery of cash by wire transfer of immediately available funds. The Purchase Price shall be subject to final determination as provided in Section 1.3.

SECTION 1.3 Final Determination of Purchase Price.

(a) Calculation of Purchase Price. As soon as reasonably practicable, but in no event later than ninety (90) days after the Closing Date, Buyer shall prepare and deliver to Seller the calculation of the Purchase Price.

(b) Examination by Seller. Upon receipt of Buyer’s calculation of the Purchase Price, Seller and Seller’s Representatives shall be permitted during the succeeding forty-five (45) day period (the “Review Period”) full access at all reasonable times to the books and records of the Company, and the personnel of, and work papers prepared by, Buyer and/or Buyer’s Representatives to the extent that they relate to the Company and to such historical financial information relating to the Company as Seller may reasonably request for the purpose of reviewing

Buyer’s calculation of the Purchase Price Adjustment Items. The parties hereto acknowledge and agree that Seller may retain Xxxxx Xxxxxxxx Xxxxx for the purpose of assisting Seller in its review of Buyer’s calculation of the Purchase Price Adjustment Items.

(c) Objection by Seller. On or prior to the last day of the Review Period, Seller may object to Buyer’s calculation of the Purchase Price Adjustment Items by delivering to Buyer a written statement setting forth a reasonable basis for Seller’s objections to Buyer’s calculation of the Purchase Price Adjustment Items (the “Statement of Objections”). If Seller fails to deliver the Statement of Objections within the Review Period, Buyer’s calculation of the Purchase Price Adjustment Items shall be deemed to have been accepted by Seller and shall be used in computing the difference between the Purchase Price and the Closing Payment (the “Adjustment Amount”). If Seller delivers the Statement of Objections within the Review Period, Seller and Buyer shall negotiate in good faith to resolve such objections, and, if the same are so resolved, the calculation of the Purchase Price with such changes to the Purchase Price Adjustment Items as may have been previously agreed in writing by Seller and Buyer shall be final and binding.

(d) Resolution of Disputes. If Seller and Buyer shall fail to reach an agreement with respect to all of the matters set forth in the Statement of Objections, then such matters shall, not later than fifteen (15) days after one of the parties affirmatively terminates discussions in writing with respect to the Statement of Objections, be submitted for resolution to the New York office of KPMG LLP (the “Accounting Expert”) who shall, acting as experts and not as arbitrators, resolve the disputes set forth in the Statement of Objections and make any adjustments to the calculation of the Purchase Price.

(e) Fees of the Accounting Expert. The fees of the Accounting Expert shall be divided equally between Seller and Buyer.

(f) Access to Supporting Documentation. Subject to, and to the extent permitted by, any applicable Laws, Seller and Buyer and their respective Representatives shall each make readily available to the Accounting Expert all relevant work papers and books and records relating to the Company and those relating to Seller (but only to the extent that they relate to the Company), and copies of all such materials and information provided by a party to the Accounting Expert shall be concurrently delivered to the other party to the proceeding.

(g) Determination by Accounting Expert. The parties shall jointly instruct the Accounting Expert to make a determination as soon as practicable within thirty (30) days (or such other time as the parties hereto shall agree in writing) after its engagement and its resolution of the dispute and its adjustments to the calculation of the Purchase Price shall be conclusive and binding upon the parties hereto.

(h) Payment of Adjustment Amount. Within two (2) Business Days of the later of (i) acceptance of Buyer’s calculation of the Purchase Price Adjustment Items or (ii) the resolution of Seller’s objections in connection therewith, to the extent that the Purchase Price is less than or more than the Closing Payment, Seller shall pay to Buyer (if the Purchase Price is less than the Closing Payment) or Buyer shall pay to Seller (if the Purchase Price is greater than the Closing Payment), as the case may be, the Adjustment Amount together with interest thereon

equal to LIBOR calculated on the basis of a 360-day year and the actual number of days elapsed from the Closing Date to the date on which the Adjustment Amount is paid. Any such payment shall be in United States dollars in federal or other immediately available funds as directed by Buyer or Seller, as the case may be.

ARTICLE II
CLOSING

SECTION 2.1 Closing. Unless otherwise mutually agreed in writing between Seller and Buyer, the closing for the sale and purchase of the Membership Interests (the “Closing”) shall take place at the offices of Xxxxxxxx & Xxxxxxxx LLP, 000 Xxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx, at 9:00 A.M. on the later of (i) July 31, 2006 or (ii) the third (3rd) Business Day (the “Closing Date”) following the day on which the last to be fulfilled or waived of the conditions set forth in Article VI (other than those conditions that either by their nature or expressly are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions) shall be satisfied or waived in accordance with this Agreement.

(a) violate the Certificate of Incorporation or By-laws of Seller or the Company’s Organizational Documents;

(b) contravene, conflict with, or constitute or result in a breach or violation of, or a default under, or the cancellation, modification or termination of, or the acceleration of, or the creation of a Lien on any properties or assets owned or used by the Company pursuant to, any provision of any Contract under which Seller or the Company is bound or by which any of their respective assets are bound, in each case other than as set forth in Schedule 3.5(b) of the Disclosure Schedule;

The initial press release announcing the transactions contemplated herein shall be released jointly after consultation between the parties hereto and thereafter the parties hereto shall consult with each other prior to issuing any press releases or otherwise making any public announcements with respect to the transactions contemplated herein and prior to making any filings with any Governmental Entity or with any national securities exchange with respect thereto, except as may be required by Law or by obligations pursuant to any listing agreement with or rules of any national securities exchange on which the securities of Ultimate Parent or Buyer are listed (in which case, the disclosing party shall make a good faith effort to notify the other party of such press release or public statement and provide the other party

a copy of the proposed press release or public statement and an opportunity to provide comments thereon (which comments the disclosing party shall not unreasonably refuse to incorporate into such release or public announcement, except where such public statement is a filing under the federal securities laws, in which case the disclosing party may refuse to incorporate such comments in its sole discretion) at least two (2) Business Days prior to the time the release or statement is made public).

the date of this Agreement and the Closing Date, the notifying party shall promptly notify the other of the occurrence of any breach of any covenant, agreement, undertaking or obligation of it in this Article V or of the occurrence of any event that may make the satisfaction of the conditions in Article VI impossible or not reasonably likely.

Nothing in this Section 5.9(a) shall prohibit Seller from acquiring, directly or indirectly, control of a company (a “Subject Company”) if the Subject Company is not primarily engaged, directly or indirectly, in a Competing Business; provided that if in respect of any fiscal year during the sixty (60) months following the Closing Date the revenues Seller has received from the Subject Company that were generated from the provision of services that constitute a Competing Business exceed 10% of the total revenues Seller has received from the Subject Company, Seller shall divest the business of the Subject Company that provides the services that constitute a Competing Business within twelve (12) months from such fiscal year end.

(b) Non-Solicitation.

(i) Seller hereby covenants and agrees that for a period of twenty-four (24) months following the Closing Date neither it nor any of its Subsidiaries or Related Persons shall, without the prior written consent of Buyer, directly or indirectly, solicit for employment any current employee of the Company (other than the individuals listed in Schedule 5.9(b) of the Disclosure Schedule, such individuals the “Retained Employees”); and

Buyer expressly acknowledges that the Closing Payment reflects an adjustment in Buyer’s favor in respect of such anticipated severance expenses. All service with Seller, the Company or any ERISA Affiliate of Seller prior to the Closing Date by any Acquired Employee shall be treated as if it were service with Buyer or any of Buyer’s Affiliates for purposes of determining such severance benefits and for purposes of eligibility, vesting and accrual of benefits under all employee benefit plans provided to such Acquired Employee by the Company or Buyer following the Closing Date (other than accrual of benefits under defined benefit retirement plans), such determination, in each case, to be made on a basis consistent with Seller’s and the Company’s policies, except to the extent prohibited by applicable Law.

(e) Buyer shall cause one or more defined contribution plans maintained by Buyer, the Company or their Affiliates after the Closing Date to accept a direct rollover pursuant to Section 401(a)(31) of the Code of any eligible rollover distribution from any Seller Benefit Plan that is a qualified defined benefit or defined contribution plan which has been elected by any Acquired Employee who remains an employee of the Company on the date the distribution is made. Such a direct rollover may include the rollover in kind of any participant loan outstanding to the individual under such a qualified defined contribution plan on the date the direct rollover occurs.

Buyer shall promptly reimburse Seller for any payments Seller or such Affiliate makes on or after the Closing in respect of such obligations.

SECTION 5.13 Plant Closings.

During such six-(6) month period, Buyer and its Affiliates (including the Company) shall not use any reference to the name “Teris” or any other name, phrase or logo confusingly similar to any trademark currently in use by Seller or its Affiliates or any other trademark which may imply an association with or sponsorship by Seller or its Affiliates, other than within the continental United States.

Notwithstanding clause (ii) above, Seller may, at any time and at its option, notify Buyer and the Company that it will assume and thereafter control, at its own expense, the management of any specified litigation in respect of the El Dorado Incidents. In the event Seller elects to assume and control the management of any such litigation, Buyer shall, and shall cause the Company to, fully cooperate with Seller with respect thereto, including providing Seller access to such books and records of the Company, and to such Company personnel, as Seller may deem necessary or desirable, and shall take all such further actions as Seller may request from time to time, in order to facilitate Seller’s management thereof.

SECTION 5.18 Pending Claims Related to El Dorado Incidents. Immediately prior to Closing, in the event that the Company has not recovered fully on receivables for expected insurance reimbursement arising from the El Dorado Incidents (or on deductibles paid or other uninsured loss related thereto), Seller may, at its option, cause the Company to assign its rights in respect thereto to Seller or any of its Affiliates, and thereafter, Seller or such Affiliate may, at its own expense, continue to pursue such claims. In the event that Seller does not elect to cause the Company to effect such assignment, or such assignment by the Company is determined to be illegal or impermissible for any reason, then following the Closing, Buyer agrees to, and to cause the Company to, use its reasonable best efforts to pursue such claims, at Seller’s expense, and to promptly deliver to Seller any receivables or recoveries that the Company receives in respect thereof.

SECTION 8.5 Notice and Payment of Claims.

(a) Notice. Subject to the provisions of Section 8.6 of this Agreement, the Indemnified Party shall notify the Indemnifying Party as soon as reasonably practicable, but in no event later than ten (10) days, after the Indemnified Party becomes aware of, and shall provide to the Indemnifying Party as soon as practicable thereafter all information and documentation necessary to support and verify, any Damages that the Indemnified Party shall have determined to have given rise to a claim for indemnification hereunder, and the Indemnifying Party shall be given access to all books and records in the possession or under the control of the Indemnified Party which the Indemnifying Party reasonably determines to be related to such claim.

(b) Any Indemnifying Party will have the right at any time to assume and thereafter conduct the defense of the Third Party Claim with counsel of its choice reasonably satisfactory to the Indemnified Party; provided, however, that the Indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party (not to be withheld unreasonably) unless the judgment or proposed settlement involves only the payment of money damages and does not impose an injunction or other equitable relief upon the Indemnified Party.

(i) net proceeds received by such Indemnified Party from any insurance policy of the Company in effect at any time prior to the Closing (less the costs of recovering such proceeds, retrospective premium adjustments, experience-based premium adjustments or other forms of self-insurance), with respect thereto, from which policies the parties hereto shall make claims for recovery; or

(ii) any offsetting Tax benefits received or to be received by the Indemnified Party.

The parties hereto acknowledge and agree that, subject to the provisions of Sections 10.6 and 10.8(e) of this Agreement, the foregoing indemnification provisions in this Article VIII shall be the exclusive remedy of the parties with respect to the transactions contemplated by this Agreement (other than as otherwise expressly provided herein).

ARTICLE IX
TAX MATTERS

SECTION 9.1 Liability for Taxes and Related Matters.

(a) Seller Liability for Taxes. Except to the extent treated as a liability in the calculation of the Working Capital Adjustment, Seller shall be liable for and indemnify Buyer for all Taxes imposed on or due from the Company (i) for any taxable year or period that ends on or before the Closing Date (a “Pre-Closing Period”), and (ii) with respect to any taxable year or period beginning before and ending after the Closing Date (a “Straddle Period”), the portion of such taxable year ending on and including the Closing Date. Except to the extent treated as an asset in the calculation of the Working Capital Adjustment, Seller shall be entitled to any refund of Taxes of the Company received for such periods.

(b) Buyer Liability for Taxes. Buyer shall be liable for and indemnify Seller for all Taxes imposed on or due from the Company for any taxable year or period that begins after

the Closing Date (a “Post-Closing Period”) and, with respect to any Straddle Period, the portion of such taxable year beginning after the Closing Date.

(c) Taxes for Straddle Periods. To the extent permitted by law or administrative practice in each relevant jurisdiction, the taxable year of the Company shall be closed at the close of business on the Closing Date. To the extent that the taxable year of the Company is not closed pursuant to the previous sentence and it is therefore necessary to determine the liability for Taxes for a Straddle Period, the determination of the Taxes for the portion of the year or period ending on, and the portion of the year or period beginning after, the Closing Date shall be determined by assuming that the Company had a taxable year or period which ended at the close of business on the Closing Date, except that exemptions, allowances or deductions that are calculated on an annual basis (other than net operating losses and tax credits carried forward from years ending prior to the Closing Date), shall be prorated on the basis of the number of days in the annual period elapsed through the Closing Date as compared to the number of days in the annual period elapsing after the Closing Date. Net operating losses and tax credits carried forward from year ending prior to the Closing shall be allocated first, to the extent that they can be utilized, to the taxable year or period ending on the Closing Date.

(d) Adjustment to Purchase Price. Any payment by Buyer, on the one hand, or Seller, on the other hand, under this Section 9.1, pursuant to Article VIII or pursuant to Section 1.3 will be treated as an adjustment to the Purchase Price for all Tax purposes.

(e) Tax Returns. Seller shall file, or cause to be filed, when due all Tax Returns that are required to be filed by or for the Company for taxable years or periods ending on or before the Closing Date, and Buyer shall file, or cause to be filed, when due all Tax Returns that are required to be filed by or for the Company for taxable years or periods ending after the Closing Date. If Seller could be liable for any Taxes with respect to any Tax Return filed by Buyer, Buyer shall (i) cause such Tax Return to be prepared on a basis which is consistent with the Company’s Tax Returns previously filed and in accordance with past practices, (ii) deliver a copy of such Tax Return along with accompanying work papers to Seller not less than thirty (30) days prior to the due date (as extended, if applicable) for the filing of such Tax Return (the “Due Date”), (iii) if, at any time prior to the Due Date, Seller notifies Buyer that Seller objects to any item reflected on such Tax Return which item may affect Seller’s liability for Taxes, Buyer shall, prior to the Due Date, make any and all changes to such item or items requested by the Seller and Buyer shall not file any such Tax Return until it has made such changes and received Seller’s agreement thereto. If Buyer has fully complied with this Section 9.1(e) with respect to a Tax Return to be filed by Buyer, Seller shall pay Buyer the Taxes for which Seller is liable pursuant to Section 9.1(a) but which are payable with such Tax Return within five (5) days (x) prior to the Due Date for the filing of such Tax Returns or (y) after the date that Buyer has provided Seller with the revised Tax Return referred to in clause (iii) of the previous sentence, whichever is later. If Buyer fails to satisfy any of its obligations pursuant to this Section 9.1(e) with respect to any Tax Return, Seller shall, in addition to any other remedies available to Seller, have no obligation to indemnify Buyer for any Taxes reflected on such Tax Return.

(f) Contest Provisions. Buyer shall promptly notify Seller and provide a copy of such notification to the Tax Director of Seller Parent in writing upon receipt by Buyer, any of its Affiliates or the Company of notice of any pending, proposed, threatened or actual Tax audit or Tax deficiency, assessment or other claim which may affect the Taxes for any Pre-Closing Period or any Straddle Period for which Seller would be liable pursuant to Section 9.1(a).

GUARANTEE

GUARANTEE dated as of ______________, 2006 by Suez Environnement, S.A., a société anonyme incorporated under the laws of France (the “Guarantor”), in favor of Clean Harbors, Inc., a Massachusetts corporation (the “Guaranteed Party”).

Section 1. Guarantee. The Guarantor absolutely, unconditionally and irrevocably guarantees to the Guaranteed Party the prompt payment when due, subject to any applicable grace period, of all present and future payment obligations (the “Obligations”) of SITA U.S.A., Inc. (the “Obligor”) to the Guaranteed Party under Section 8.2 and Section 9.1(a) of the Purchase and Sale Agreement, dated as of May 3, 2006 (the “Guaranteed Agreement”), between the Obligor and the Guaranteed Party. For the avoidance of doubt, Guarantor’s obligations hereunder shall be subject to compliance by the Guaranteed Party with the provisions of Article VIII and Article IX, as the case may be, of the Guaranteed Agreement, and in no event shall exceed the limitations on the Obligor’s indemnification obligations set forth in Section 8.4 of the Guaranteed Agreement.

Section 2. Nature of Guarantee. The Guarantor’s obligations hereunder shall not be affected by the existence, validity, enforceability, perfection or extent of any collateral for the Obligations or by any other circumstance relating to the Obligations that might otherwise constitute a legal or equitable discharge of or defense to the Guarantor, except that, save as expressly provided herein, the Guarantor does not waive any defense that is available to the Obligor. The Guarantor agrees that the Guaranteed Party may resort to the Guarantor for payment of any of the Obligations whether or not such Guaranteed Party shall have resorted to any collateral therefor or shall have proceeded against the Obligor or any other obligor principally or secondarily obligated with respect to any of the Obligations. The Guaranteed Party shall not be obligated to file any claim relating to the Obligations in the event that the Obligor becomes subject to a bankruptcy, reorganization or similar proceeding, and the failure of the Guaranteed Party so to file shall not affect the Guarantor’s obligations hereunder. In the event that any payment to the Guaranteed Party in respect of any Obligation is rescinded or must otherwise be returned for any reason whatsoever, the Guarantor shall remain liable hereunder with respect to such Obligation as if such payment had not been made. The Guarantor reserves the right to assert defenses which the Obligor may have to payment of any Obligation other than (a) defenses arising from the bankruptcy or insolvency of the Obligor and (b) defenses based on (i) the corporate status of the Obligor and (ii) the power and authority of the Obligor to enter into the Guaranteed Agreement and to perform its obligations thereunder or the failure by the Obligor to obtain any necessary consents to enter into any of the Guaranteed Agreement or to perform the said obligations.

Section 3. Subrogation. The Guarantor will not exercise any rights which it may acquire by way of subrogation until all the Obligations to the Guaranteed Party shall have been indefeasibly paid in full. Subject to the foregoing, upon payment of any of the Obligations, the Guarantor shall be subrogated to the rights of the Guaranteed Party against the Obligor with respect to the Obligations, and the Guaranteed Party agree to take at the Guarantor’s expense such steps as the Guarantor may reasonably request to implement such subrogation.

Section 4. No Waiver; Cumulative Rights. No failure on the part of the Guaranteed Party to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by the Guaranteed Party of any right, remedy or power hereunder preclude any other or future exercise of any right, remedy or power. Each and every right, remedy and power hereby granted to the Guaranteed Party or allowed it by law or other agreement shall be cumulative and not exclusive of any other, and may be exercised by the Guaranteed Party at any time or from time to time.

Section 5. Representations and Warranties. The Guarantor hereby represents and warrants as of the date of this Guarantee that:

(a) the Guarantor is duly organized, validly existing and in good standing under the laws of France and has full corporate power to execute, deliver and perform this Guarantee;

(b) the execution, delivery and performance of this Guarantee have been and remain duly authorized by all necessary corporate action and do not contravene any provision of the Guarantor’s certificate of incorporation or bylaws, as amended to date, or any law, regulation, rule, decree, order, judgment or contractual restriction binding on the Guarantor or its assets; and

(c) this Guarantee constitutes a legal, valid and binding obligation of the Guarantor enforceable against the Guarantor in accordance with its terms, subject to bankruptcy, insolvency, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

Section 6. Assignment. Neither the Guarantor nor the Guaranteed Party may assign its rights, interests or obligations hereunder to any other person (except by operation of law) without the prior written consent of the Guarantor or the Guaranteed Party, as the case may be.

Section 7. Notices. All notices or demands on the Guarantor shall be deemed effective when received, shall be in writing and shall be delivered by hand or by registered mail, or by facsimile transmission promptly confirmed by registered mail, addressed to the Guarantor at:

Section 9. GOVERNING LAW. THIS GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS.

Section 10. Arbitration. Any controversy or claim arising out of or relating to this Guarantee or the breach hereof shall be settled by arbitration administered by the American Arbitration Association in accordance with its Commercial Arbitration Rules, and Title 9 of the U.S. Code. Judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. The number of arbitrators shall be one (1), and such arbitrator shall be selected by mutual agreement of the Guarantor and the Guaranteed Party, if possible, and thereafter by the administering authority, and the place of arbitration shall be New York, New York. The arbitrator may award the costs of the arbitration to the prevailing party and should in so doing consider the extent (in percentage terms, if possible) to which each party has prevailed on its claims or counterclaims. The arbitrator will have no authority to award punitive damages or any other damages not measured by the prevailing party’s actual damages, and may not, in any event, make any ruling, finding or award that does not conform to the terms and conditions of this Guarantee.

IN WITNESS WHEREOF, this Guarantee has been duly executed and delivered by the Guarantor to the Guaranteed Party as of the date first above written.
