Dear Sirs:

The Offered Securities will be unconditionally guaranteed (the “Subsidiary Guarantees”) on a senior secured basis by the Company’s domestic subsidiaries listed on the signature page hereof (collectively, the “Guarantors”). The Company and the Guarantors to be party to the Indenture on the Closing Date (as defined below) are referred to collectively as the “Issuers.”

The holders of the Offered Securities will be entitled to the benefits of the Security Documents (as defined in the Indenture) and a Registration Rights Agreement dated as of June 30, 2004, among the Issuers and the Purchasers (the “Registration Rights Agreement”), pursuant to which the Issuers agree to file a registration statement under the Securities Act (the “Exchange Offer Registration Statement”) with the Securities Exchange Commission (the “Commission”) registering the offering of senior notes (the “Exchange Securities”) identical in all material respects to the Offered Securities (except that the Exchange Securities will not contain terms with respect to transfer restrictions) to be offered in exchange for the Offered Securities (the “Exchange Offer”) and, if required by the Registration Rights Agreement, a shelf registration statement (the “Shelf Registration Statement” and, together with the Exchange Offer Registration Statement, the “Registration Statements”) relating to the resale by certain holders of the Offered Securities.

Pursuant to the Security Documents, the Issuers have agreed, among other things, to grant to Credit Suisse First Boston, acting through its Cayman Islands Branch, as collateral agent (the “Collateral Agent”), for the benefit of the Trustee and the holders of the Offered Securities a second priority security interest in and lien on the Collateral (as defined in the Security Agreement described in Section 2(oo)), subject to certain exceptions and otherwise in accordance with the terms of the Indenture and the Security Documents and as described in the Offering Circular.

The Issuers, jointly and severally, hereby agree with the several Purchasers as follows:

2. Representations and Warranties of the Company. The Issuers, jointly and severally, represent and warrant to, and agree with, the several Purchasers that:

Such preliminary offering circular (the “Preliminary Offering Circular”) and offering circular (the “Offering Circular”), as supplemented as of the date of this Agreement, together with any other document approved by the Company for use in connection with the contemplated resale of the Offered Securities including such documents that are incorporated by reference therein are hereinafter collectively referred to as the “Offering Document.” On the date of this Agreement and the Closing Date, the Offering Document does not and will not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes (i) an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers on the one hand and the Purchasers on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Issuers on the one hand and the Purchasers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Issuers on the one hand and the Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Issuers bear to the total discounts and commissions received by the Purchasers from the Issuers under this Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuers or the Purchasers and the parties’

relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Purchaser shall be required to contribute any amount in excess of the amount by which the total discounts, fees and commissions received by such Purchaser exceeds the amount of any damages which such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Purchasers’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint.

(e) The obligations of the Issuers under this Section shall be in addition to any liability which the Issuers may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Purchaser within the meaning of the Securities Act or the Exchange Act; and the obligations of the Purchasers under this Section shall be in addition to any liability which the respective Purchasers may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Issuer within the meaning of the Securities Act or the Exchange Act.

8. Default of Purchasers. If any Purchaser or Purchasers default in their obligations to purchase Offered Securities hereunder and the aggregate principal amount Offered Securities that such defaulting Purchaser or Purchasers agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities, the Purchasers may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Purchasers, but if no such arrangements are made by the Closing Date, the non-defaulting Purchasers shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Purchasers agreed but failed to purchase. If any Purchaser or Purchasers so default and the aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities and arrangements satisfactory to the Purchasers and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Purchaser or the Company, except as provided in Section 9. As used in this Agreement, the term “Purchaser” includes any person substituted for a Purchaser under this Section. Nothing herein will relieve a defaulting Purchaser from liability for its default.

9. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Issuers or their officers and of the several Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Purchaser, any Issuer or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities . If this Agreement is terminated pursuant to Section 8 or if for any reason the purchase of the Offered Securities by the Purchasers is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Issuers and the Purchasers pursuant to Section 7 shall remain in effect.

If the purchase of the Offered Securities by the Purchasers is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 8, the Company will reimburse the Purchasers for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.

10. Notices. All communications hereunder will be in writing and, if sent to the Purchasers will be mailed, delivered or telegraphed and confirmed to the Purchasers, at Credit Suisse First Boston LLC, Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention: Transactions Advisory Group, and Xxxxxxx, Sachs & Co., 00 Xxxxx Xxxxxx, Xxx Xxxx, X.X. 00000, Xxxxxxxxx: Prospectus Department, or, if sent to the Company, will be mailed, delivered or telegraphed and confirmed to it at Clean Harbors, Inc. 0000 Xxxxxxxxxx Xx., X.X. Xxx 000 000, Xxxxxxxxx, XX 00000, Attention: Xxxx Xxxxxxx; provided, however, that any notice to a Purchaser pursuant to Section 7 will be mailed, delivered or telegraphed and confirmed to such Purchaser.

11. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the controlling persons referred to in Section 7, and no other person will have any right or obligation hereunder, except that holders of Offered Securities shall be entitled to enforce the agreements for their benefit contained in the second and third sentences of Section 5(b) hereof against the Company as if such holders were parties thereto.

12. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

13. Applicable Law. This Agreement 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.

The Issuers hereby submit to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

14. Post Closing Matters Relating to Collateral. The Issuers shall obtain and deliver to Collateral Agent, within sixty business days after the Closing Date, unless waived or extended by Collateral Agent in its sole discretion (x) a survey for the Surveyed Properties located at 000 Xxxxxxx Xxxx, Xxx Xxxx, Xx; Highway 000 Xxxxx Xxxxxxxxxx Xxxx, Xxxxxxxxxxx, XX; Hwy 1112 (0000 Xxxxx Xxxxxxxxxx Xxxx), Xxxxx, XX; 00000 Xxxxxx Xxxx, Xxxxxxxxxx, XX; Xxxxx 000 & X-000 (XX Xxx 000), Xxxxxxxxxx, XX; 0000 Xxxxxxxx Xxx, Xxxxxx, XX; 0000 Xxxxxxxxxxx Xxx., Xxxxxxxxx, XX, 0000 X.
