FOR VALUE RECEIVED, Changing World Technologies, Inc., a Delaware corporation (the “Obligor”), hereby unconditionally promises to pay to Sterling Acquisitions, LLC (the “Payee”), the principal amount set forth in Section 2 hereto, as the same may be modified or amended from time to time with the consent of the Obligor and the Payee, together with interest thereon as provided in Section 1 hereto, on the Maturity Date (as defined below), on the terms and subject to the conditions provided herein. Reference is made to that certain Collateral, Agency and Intercreditor Agreement dated on or about the date hereof (as the same may be amended, modified, supplemented or restated from time to time, the “Agreement”) among the Obligor, Resource Recovery Corporation, a Delaware corporation, the Payee, certain other creditors of the Obligor party thereto (together with the Payee, collectively, the “Secured Creditors” and each, individually, a “Secured Creditor”), and Ira B. Silver, in his capacity as collateral agent for the Secured Creditors (in such capacity, the “Agent”). The Obligor agrees, the Payee, by accepting this Note, agrees, and all subsequent holders of this Note each agree, that certain rights and obligations of the Obligor and the Payee hereunder are governed by and are subject to the terms of the Agreement, to the extent set forth therein, and in the event that there is any inconsistency between the terms contained in this Note and the terms contained in the Agreement, the terms contained in the Agreement shall prevail.

1. Interest. From the date hereof until (but not including) the date this Note is paid in full, interest shall accrue on the outstanding principal amount of this Note at a rate per annum equal to eighteen 18% percent (the “Rate”) compounded annually on each anniversary of the date hereof. The payment of accrued interest hereunder shall be deferred to the Maturity Date or to any other date when the unpaid principal amount hereof is declared or becomes due and payable. The amount of accrued interest so deferred will bear interest at the Rate, to the extent that payment of such interest is lawful, until paid in full. Upon the occurrence and during the continuance of an Event of Default (as defined below), the unpaid principal amount of this Note and, to the extent permitted by applicable law, any interest payments or any fees or other amounts owed hereunder, shall thereafter bear interest (including post petition interest in any proceeding under any applicable bankruptcy laws, whether or not allowed in such a proceeding) payable on demand at a rate that is two percent (2.0%) per annum in excess of the Rate otherwise applicable thereto pursuant to the first sentence of this Section 1 (the “Default Rate”). Interest payable pursuant hereto shall be calculated on the basis of a 360-day year for the actual days elapsed.

4. Representations and Warranties. To induce the Payee to make the Loan, the Obligor hereby represents and warrants to the Payee that:

(a) Corporate Existence; Compliance with Law. The Obligor (i) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, (ii) has the corporate power and authority, and the legal right, to own and/or lease and operate its property and to conduct the business in which it is currently engaged, (iii) is duly qualified to do business as a foreign entity and is in good standing under the laws of each jurisdiction where its ownership, lease or operation of property or the conduct of its business requires such qualification, (iv) is in material compliance with all requirements of law and (v) has all consents, licenses and authority necessary to execute this Note.

(b) Corporate Power; Authorization; Enforceable Obligations. The Obligor has the corporate power and authority, and the legal right, to make, deliver and perform the Loan Documents and to borrow hereunder. The Obligor has taken all necessary corporate or other necessary actions to authorize the execution, delivery and performance of the Loan Documents and to authorize the borrowing on the terms and conditions of this Note. All consents or authorization of, filing with, notice to or other act by or in respect of, any governmental authority or any other person, to the extent required in connection with the borrowings hereunder or the execution, delivery, performance, validity or enforceability of this Note or any of the other Loan Documents have been obtained or made, as applicable. Each Loan Document has been duly executed and delivered on behalf of the Obligor. This Note constitutes, and each other Loan Document upon execution will constitute, a legal, valid and binding obligation of the Obligor, enforceable against the Obligor in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law).

(c) No Default; Non-Contravention. The Obligor is not in violation or default of any provisions of its Certificate of Incorporation or Bylaws or, to its knowledge, of any instrument, judgment, order, writ, decree, mortgage, indenture, lease, license or contract to which it is a party or by which it is bound, except as would not reasonably be expected to have, either individually or in the aggregate, a material adverse effect on the condition, business, assets, properties, rights, results of operations or prospects of the Obligor or any of its subsidiaries (a “Material Adverse Effect”). The execution, delivery, and performance of the Loan Documents and the

consummation of the transactions contemplated thereby will not result in any such violation or be in conflict with or constitute, with or without the passage of time and giving of notice, either a default under any such provision, instrument, judgment, order, writ, decree or contract, or an event which results in the creation of any lien, charge, or encumbrance upon any assets of the Obligor or the suspension, revocation, impairment, forfeiture, or nonrenewal of any material permit, license, authorization, or approval applicable to the Obligor, its business or operations, or any of its assets or properties, except as would not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect.

(d) Title to Assets; No Encumbrances. With respect to the property and assets it owns, the Obligor owns such property and assets free and clear of all mortgages, liens, loans, pledges, security interests, claims, equitable interests, charges, and encumbrances, except such encumbrances and liens which arise in the ordinary course of business and do not impair in any material respect the Obligor’s ownership or use of such property or assets. With respect to the property and assets it leases, the Obligor is in compliance with such leases and, to its knowledge, holds a valid leasehold interest free of any liens, claims, or encumbrances.

(e) Securities Matters. Neither the Obligor nor any of its agents has engaged in any form of general solicitation or general advertising (within the meaning of Regulation D promulgated under the Securities Act of 1933, as amended) in connection with the transactions contemplated by the Loan Documents.

(f) Indebtedness. As of the date hereof, the Obligor has no indebtedness for borrowed money, other than the indebtedness owing to the other Secured Creditors and evidenced by the promissory notes executed by the Obligor on or about the date hereof and payable to each such other Secured Creditor, nor has it guaranteed or agreed to be liable for the payment of any such indebtedness of any other person or entity and the Obligor has no obligation or agreement to incur any indebtedness for borrowed money.

The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions. Each waiver in this Note is subject to the overriding and controlling rule that it shall be effective only if and to the extent that (a) it is not prohibited by applicable law and (b) applicable law neither provides for nor allows any material sanctions to be imposed against Payee for having bargained for and obtained it.
