(1) unless the Collateral Agent elects otherwise and gives written notice following the occurrence of such Event of Default to the Grantors, all rights of each Grantor to exercise or refrain from exercising the voting and other consensual rights which it would otherwise be entitled to exercise pursuant hereto shall cease and all such rights shall thereupon become vested in the Collateral Agent which shall thereupon have the sole right to exercise such voting and other consensual rights as permitted by law; and

(2) in order to permit the Collateral Agent to exercise the voting and other consensual rights which it may be entitled to exercise pursuant hereto and to receive all dividends and other distributions which it may be entitled to receive hereunder: (a) each Grantor shall promptly execute and deliver (or cause to be executed and delivered) to the Collateral Agent all proxies, dividend payment orders and other instruments as the Collateral Agent may from time to time reasonably request and (b) each Grantor acknowledges that the Collateral Agent may utilize the power of attorney set forth in Section 6.

Each Grantor agrees that it would not be commercially unreasonable for the Collateral Agent to dispose of the Collateral or any portion thereof by using Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets. Each Grantor hereby waives any claims against the Collateral

Agent arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price which might have been obtained at a public sale, even if the Collateral Agent accepts the first offer received and does not offer such Collateral to more than one offeree. If the proceeds of any sale or other disposition of the Collateral are insufficient to pay all the Secured Obligations, each Grantor shall be liable for the deficiency and the fees of any attorneys employed by the Collateral Agent to collect such deficiency. Each Grantor further agrees that a breach of any of the covenants contained in this Section will cause irreparable injury to the Collateral Agent, that the Collateral Agent has no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section shall be specifically enforceable against such Grantor, and such Grantor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no default has occurred giving rise to the Secured Obligations becoming due and payable prior to their stated maturities. Nothing in this Section shall in any way alter the rights of the Collateral Agent hereunder.

(iii) The Collateral Agent may sell the Collateral without giving any warranties as to the Collateral. The Collateral Agent may specifically disclaim or modify any warranties of title or the like. This procedure will not be considered to adversely effect the commercial reasonableness of any sale of the Collateral.

(iv) The Collateral Agent shall have no obligation to ▇▇▇▇▇▇▇▇ any of the Collateral.

(v) The Collateral Agent agrees that prior to foreclosing on or exercising any remedies with respect to the equity interests in Duke/UAE Ref-Fuel LLC pledged pursuant to this Agreement, the Collateral Agent will comply with the right of first offer provisions contained in the Duke/UAE Ref-Fuel LLC Limited Liability Company Agreement.

(b) Application of Proceeds. Except as expressly provided elsewhere in this Agreement, all proceeds received by the Collateral Agent in respect of any sale, any collection from, or other realization upon all or any part of the Collateral shall be applied in full or in part by the Collateral Agent against, the Secured Obligations in the following order of priority: first, to the payment of all costs and expenses of such sale, collection or other realization, including reasonable compensation to the Collateral Agent and its agents and counsel, and all other expenses, liabilities and advances made or incurred by the Collateral Agent in connection therewith, and all amounts for which the Collateral Agent is entitled to indemnification hereunder (in its capacity as the Collateral Agent) and all advances made by the Collateral Agent hereunder for the account of the applicable Grantor, and to the payment of all costs and expenses paid or incurred by the Collateral Agent in connection with the exercise of any right or remedy hereunder or under any Transaction Document, all in accordance with the terms hereof or thereof; second, to the extent of any excess of such proceeds, to the payment of all other Secured Obligations for the ratable benefit of each Secured Party; and third, to the extent of any excess of such proceeds, to the payment to or upon the order of such Grantor or to whosoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct.

(c) Sales on Credit. If Collateral Agent sells any of the Collateral upon credit, Grantor will be credited only with payments actually made by purchaser and received by Collateral Agent and applied to indebtedness of the purchaser. In the event the purchaser fails to pay for the Collateral, Collateral Agent may resell the Collateral and Grantor shall be credited with proceeds of the sale.

(d) Investment Related Property.

(i) Each Grantor recognizes that, by reason of certain prohibitions contained in the Securities Act of 1933, as amended, (the "Securities Act") and applicable state securities laws, the Collateral Agent may be compelled, with respect to any sale of all or any part of the Investment Related Property conducted without prior registration or qualification of such Investment Related

Property under the Securities Act and/or such state securities laws, to limit purchasers to those who will agree, among other things, to acquire the Investment Related Property for their own account, for investment and not with a view to the distribution or resale thereof. Each Grantor acknowledges that any such private sale may be at prices and on terms less favorable than those obtainable through a public sale without such restrictions (including a public offering made pursuant to a registration statement under the Securities Act) and, notwithstanding such circumstances, each Grantor agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner and that the Collateral Agent shall have no obligation to engage in public sales and no obligation to delay the sale of any Investment Related Property for the period of time necessary to permit the issuer thereof to register it for a form of public sale requiring registration under the Securities Act or under applicable state securities laws, even if such issuer would, or should, agree to so register it. If the Collateral Agent determines to exercise its right to sell any or all of the Investment Related Property, upon written request, each Grantor shall and shall cause each issuer of any Pledged Stock to be sold hereunder, each partnership and each limited liability company from time to time to furnish to the Collateral Agent all such information as the Collateral Agent may request in order to determine the number and nature of interest, shares or other instruments included in the Investment Related Property which may be sold by the Collateral Agent in exempt transactions under the Securities Act and the rules and regulations of the Securities and Exchange Commission thereunder, as the same are from time to time in effect.

(ii) Upon the occurrence and during the continuation of an Event of Default, the Collateral Agent shall have the right to apply the balance from any Deposit Account or instruct the bank at which any Deposit Account is maintained to pay the balance of any Deposit Account to or for the benefit of the Collateral Agent.

Section 8. COLLATERAL AGENT.

The Collateral Agent has been appointed to act as Collateral Agent hereunder by each Secured Party either pursuant to the Transaction Documents or by their acceptance of the benefits hereof. The Collateral Agent shall be obligated, and shall have the right hereunder, to make demands, to give notices, to exercise or refrain from exercising any rights, and to take or refrain from taking any action (including, without limitation, the release or substitution of Collateral), solely in accordance with this Agreement and the Indenture. Without the written consent of the Collateral Agent that would be affected thereby, no amendment, modification, termination, or consent shall be effective if the effect thereof would release all or substantially all of the Collateral except as expressly provided herein. In furtherance of the foregoing provisions of this Section, each Secured Party, by its acceptance of the benefits hereof, agrees that it shall have no right individually to realize upon any of the Collateral hereunder, it being understood and agreed by such Secured Party that all rights and remedies hereunder may be exercised solely by the Collateral Agent for the benefit of each Secured Party in accordance with the terms of this Section. Collateral Agent may resign at any time by giving thirty (30) days' prior written notice thereof to each Secured Party and the Grantors, and Collateral Agent may be removed at any time with or without cause by an instrument or concurrent instruments in writing delivered to the Grantors and Collateral Agent signed by the parties holding more than 50% of the Secured Obligations, including for this purpose any unfunded commitments (the "Requisite Parties"). Upon any such notice of resignation or any such removal, the Requisite Parties shall have the right, upon five (5) Business Days' notice to the Collateral Agent, following receipt of the Grantors' consent (which shall not be unreasonable withheld or delayed and which shall not be required while an Event of Default exists), to appoint a successor Collateral Agent. Upon the acceptance of any appointment as Collateral Agent hereunder by a successor Collateral Agent, that successor Collateral Agent under this Agreement shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring or removed Collateral Agent under this Agreement, and the

retiring or removed Collateral Agent under this Agreement shall promptly (i) transfer to such successor Collateral Agent all sums, Securities and other items of Collateral held hereunder, together with all records and other documents necessary or appropriate in connection with the performance of the duties of the successor Collateral Agent under this Agreement, and (ii) execute and deliver to such successor Collateral Agent such amendments to financing statements, and take such other actions, as may be necessary or appropriate in connection with the assignment to such successor Collateral Agent of the security interests created hereunder, whereupon such retiring or removed Collateral Agent shall be discharged from its duties and obligations under this Agreement. After any retiring or removed Collateral Agent's resignation or removal hereunder as the Collateral Agent, the provisions of this Agreement shall inure to its benefit as to any actions taken or omitted to be taken by it under this Agreement while it was the Collateral Agent hereunder.

Section 9. CONTINUING SECURITY INTEREST; TRANSFER OF SECURED OBLIGATIONS

This Agreement shall create a continuing security interest in the Collateral and shall remain in full force and effect until the payment in full of all Secured Obligations, the cancellation or termination of the commitments and any other contingent obligation included in the Secured Obligations, be binding upon each Grantor, its successors and assigns, and inure, together with the rights and remedies of the Collateral Agent hereunder, to the benefit of the Collateral Agent and its successors, transferees and assigns. Without limiting the generality of the foregoing, but subject to the terms of the Transaction Documents, each Secured Party may assign or otherwise transfer any Secured Obligations held by it to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to each Secured Party herein or otherwise. Upon the payment in full of all Secured Obligations, the cancellation or termination of the commitments and any other contingent obligation included in the Secured Obligations, the security interest granted hereby shall terminate hereunder and of record and all rights to the Collateral shall revert to Grantors. Upon any such termination the Collateral Agent shall, at Grantors' expense, execute and deliver to Grantors such documents as Grantors shall reasonably request to evidence such termination.

Section 10. STANDARD OF CARE; COLLATERAL AGENT MAY PERFORM

The powers conferred on the Collateral Agent hereunder are solely to protect its interest in the Collateral and the interests of the Secured Parties and shall not impose any duty upon it to exercise any such powers. Except for the exercise of reasonable care in the custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Collateral Agent shall have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral. The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of Collateral in its possession if such Collateral is accorded treatment substantially equal to that which the Collateral Agent accords its own property. Neither the Collateral Agent nor any of its directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or otherwise. If any Grantor fails to perform any agreement contained herein, the Collateral Agent may itself perform, or cause performance of, such agreement, and the expenses of the Collateral Agent incurred in connection therewith shall be payable by each Grantor under the Section in this Agreement relating to the payment of expenses pursuant to Section 12(b) hereof.

Section 11. INDEMNITY AND EXPENSES

Each Grantor agrees:

(i) to defend, indemnify, pay and hold harmless each Indemnitee, from and against any and all claims, losses and liabilities in any way relating to, growing out of or resulting from this Agreement and the transactions contemplated hereby (including without limitation enforcement of this Agreement), except to the extent such claims, losses or liabilities result from such Indemnitee's gross negligence or willful misconduct; and

(ii) to pay to the Collateral Agent promptly following written demand the amount of any and all reasonable costs and reasonable expenses, including the reasonable fees and expenses of its counsel and of any experts and agents in accordance with the terms and conditions of the Indenture.

(iii) The obligations of each Grantor in this Section 11 shall survive the termination of this Agreement and the discharge of such Grantor's other obligations under this Agreement, the Indenture and any other Transaction Documents.

Section 12. MISCELLANEOUS

(a) Notices. Unless otherwise specifically provided herein, any notice or other communication herein required or permitted to be given to a Grantor or Collateral Agent, shall be sent to such Person's address as set forth below or, if not set forth below, then in the other relevant Transaction Document. Each notice hereunder shall be in writing and may be personally served, telexed or sent by telefacsimile or United States mail or courier service and shall be deemed to have been given when delivered in person or by courier service and signed for against receipt thereof, upon receipt of telefacsimile or telex, or three (3) Business Days after depositing it in the United States mail with postage prepaid and properly addressed; provided, that no notice to Collateral Agent shall be effective until received by Collateral Agent.

Whether or not the transactions contemplated under the Transaction Documents shall be consummated, Grantors agree to pay promptly all the actual and reasonable costs and expenses of the Collateral Agent in connection with the preparation of the Transaction Documents and any consents, amendments, waivers or other modifications thereto; the reasonable fees, expenses and disbursements of counsel to the Collateral Agent in connection with the negotiation, preparation, execution and administration of the Transaction Documents and any consents, amendments, waivers or other modifications thereto and any other documents or matters requested by the Grantors; all the actual costs and reasonable expenses of creating and perfecting Liens in favor of Collateral Agent, for the benefit of each Secured Party pursuant hereto, including filing and recording fees, expenses and taxes, stamp or documentary taxes, search fees, title insurance premiums and reasonable fees, expenses and disbursements of counsel to Collateral Agent and of counsel providing any opinions that Collateral Agent may request in respect of the Collateral or the Liens created pursuant to the Collateral Documents; and all the actual costs and reasonable expenses (including the reasonable fees, expenses and disbursements of any appraisers, consultants, advisors and agents employed or retained by Collateral Agent and its counsel) in connection with the custody or preservation of any of the Collateral; and after the occurrence of a Default or an Event of Default, all costs and expenses, including reasonable attorneys' fees (including allocated costs of internal counsel) and costs of settlement, incurred by Collateral Agent in enforcing any Secured Obligations of or in collecting any payments due from any Grantor hereunder or under the other Transaction Documents by reason of such Default or Event of Default (including in connection with the sale of, collection from, or other realization upon any of the Collateral) or in connection with any refinancing or restructuring of the credit arrangements provided hereunder in the nature of a "work-out" or pursuant to any insolvency or bankruptcy cases or proceedings.

(i) Collateral Agent's Consent. Subject to Section 12(c)(ii), no amendment, modification, termination or waiver of any provision of this Agreement, or consent to any departure by any Grantor therefrom, shall in any event be effective without the written concurrence of the Collateral Agent.

(ii) No Waiver; Remedies Cumulative. No failure or delay on the part of the Collateral Agent in the exercise of any power, right or privilege hereunder or under any other Transaction Document shall impair such power, right or privilege or be construed to be a waiver of any default or acquiescence therein, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other power, right or privilege. All rights, powers and remedies existing under this Agreement and the other Transaction Documents are cumulative, and not exclusive of, any rights or remedies otherwise available. Any forbearance or failure to exercise, and any delay in exercising, any right, power or remedy hereunder shall not impair any such right, power or remedy or be construed to be a waiver thereof, nor shall it preclude the further exercise of any such right, power or remedy.

(d) Successors and Assigns. This Agreement shall be binding upon the parties hereto and their respective successors and assigns including all persons who become bound as debtor to this Agreement.

No Grantor shall, without the prior written consent of the Collateral Agent, assign any right, duty or obligation hereunder.

(e) Independence of Covenants. All covenants hereunder shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or would otherwise be within the limitations of, another covenant shall not avoid the occurrence of a Default or an Event of Default if such action is taken or condition exists.

(f) Survival of Representations, Warranties and Agreements. All representations, warranties and agreements made herein shall survive the execution and delivery hereof. Notwithstanding anything herein or implied by law to the contrary, the agreements of each Grantor set forth in Sections 11 and 12(b) shall survive the payment of the Secured Obligations and the termination hereof.

(g) Marshaling; Payments Set Aside. Collateral Agent shall not be under any obligation to marshal any assets in favor of any Grantor or any other Person or against or in payment of any or all of the Secured Obligations.

(h) Severability. In case any provision in or obligation hereunder shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby.

(i) Headings. Section headings herein are included herein for convenience of reference only and shall not constitute a part hereof for any other purpose or be given any substantive effect.

(j) APPLICABLE LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

(k) CONSENT TO JURISDICTION. ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST ANY GRANTOR ARISING OUT OF OR RELATING HERETO OR ANY OTHER TRANSACTION DOCUMENT, OR ANY OF THE OBLIGATIONS, MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN TH▇ ▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇ ▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇. BY EXECUTING AND DELIVERING THIS AGREEMENT, EACH GRANTOR, FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, IRREVOCABLY ACCEPTS GENERALLY AND UNCONDITIONALLY THE NONEXCLUSIVE JURISDICTION AND VENUE OF SUCH COURTS; WAIVES ANY DEFENSE OF FORUM NON CONVENIENS; AGREES THAT SERVICE OF ALL PROCESS IN ANY SUCH PROCEEDING IN ANY SUCH COURT MAY BE MADE BY REGISTERED OR CERTIFIED MAIL, RETURN RECEIPT REQUESTED, TO THE APPLICABLE GRANTOR AT ITS ADDRESS PROVIDED IN ACCORDANCE WITH SECTION 12; AGREES THAT SERVICE AS PROVIDED IN SECTION 12(a) ABOVE IN SUFFICIENT TO CONFER PERSONAL JURISDICTION OVER THE APPLICABLE GRANTOR IN ANY SUCH PROCEEDING IN ANY SUCH COURT, AND OTHERWISE CONSTITUTES EFFECTIVE AND BINDING SERVICE IN EVERY RESPECT; AND AGREES COLLATERAL AGENT RETAINS THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO BRING PROCEEDINGS AGAINST ANY GRANTOR IN THE COURTS OF ANY OTHER JURISDICTION.

(l) WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY AGREES TO WAIVE ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING HEREUNDER OR UNDER ANY OF THE OTHER TRANSACTION DOCUMENTS. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS TRANSACTION, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS AND ALL OTHER

COMMON LAW AND STATUTORY CLAIMS. EACH PARTY HERETO ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL INDUCEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT EACH HAS ALREADY RELIED ON THIS WAIVER IN ENTERING INTO THIS AGREEMENT, AND THAT EACH WILL CONTINUE TO RELY ON THIS WAIVER IN ITS RELATED FUTURE DEALINGS.

THIS WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING (OTHER THAN BY A MUTUAL WRITTEN WAIVER SPECIFICALLY REFERRING TO THIS SECTION 12(l) AND EXECUTED BY EACH OF THE PARTIES HERETO), AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS HERETO. IN THE EVENT OF LITIGATION, THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

(m) Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same instrument.

(n) Effectiveness. This Agreement shall become effective upon the execution of a counterpart hereof by each of the parties hereto and receipt by Grantors and the Collateral Agent of written or telephonic notification of such execution and authorization of delivery thereof.

(o) Entire Agreement.
