      Requisite Obligees may request (regardless of whether any individual Party
      or any other Secured Party agrees, disagrees or abstains with respect to
      such request), that Collateral Agent shall have no liability for acting in
      accordance with such request (provided such action does not conflict with
      the express terms of this Agreement) and that no Secured Party shall have
      any liability to any other Party for any such request, except, in each
      case, liability arising from the gross negligence or willful misconduct of
      such Person. Collateral Agent shall give prompt notice to all Secured
      Parties of actions taken pursuant to the instructions of Requisite
      Obligees; provided, however, that the failure to give any such notice
      shall not impair the right of Collateral Agent to take any such action or
      the validity or enforceability under this Agreement and the applicable
      Collateral Documents of the action so taken.

            (c) Collateral Agent may at any time request directions from the
      Requisite Obligees with respect to the Collateral Documents as to any
      course of action or other matter relating hereto or to the Collateral
      Documents. Except as otherwise provided in the Collateral Documents,
      directions given by Requisite Obligees to Collateral Agent with respect to
      the Collateral and Collateral Documents shall be binding on all Secured
      Parties for all purposes (provided such directions do not conflict with
      the express terms of this Agreement).

            (d) Each Secured Party, by accepting the benefits hereof and of the
      Collateral Documents, agrees not to take any Enforcement Action
      whatsoever, in each case except through Collateral Agent in accordance
      with this Agreement.

            2.3 NET INSURANCE/CONDEMNATION PROCEEDS.

            (a) Unless prohibited by contractual or other legal requirement, all
      policies of insurance required to be maintained under any Credit Document
      shall (a) name Collateral Agent, for the benefit of Secured Parties, as an
      additional insured thereunder as its interests may appear and (b) in the
      case of each business interruption and casualty insurance policy, contain
      a loss payable clause or endorsement, satisfactory in form and substance
      to Revolver Loan Agent and Term Loan Agent, that names Collateral Agent
      for the benefit of Secured Parties as the loss payee thereunder for any
      covered loss in excess of $1,000,000 and provides for at least 30 days
      prior written notice to Collateral Agent of any modification or
      cancellation of such policy. As soon as practicable after the Closing
      Date, Company shall deliver to Agents, a certificate from Borrowers'
      insurance broker(s) or other evidence satisfactory to it that all
      insurance required to be maintained pursuant to this subsection 2.3 is in
      full force and effect and that Collateral Agent on behalf of Secured
      Parties has been named as additional insured and/or loss payee thereunder
      to the extent required under this subsection 2.3.

            (b) Upon receipt by Collateral Agent of any Net
      Insurance/Condemnation Proceeds as loss payee, (a) if and to the extent
      Company would have been required to apply such Net Insurance/Condemnation
      Proceeds (if it had received them directly) pursuant to the Revolver
      Credit Agreement (or, if the Revolver Loan Obligations have been Paid in
      Full, the Term Loan Agreement), Collateral Agent shall, and Company hereby
      authorizes Collateral Agent to, apply such Net Insurance/Condemnation
      Proceeds as provided in subsection 4.1(b) or, to the extent applicable,
      subsection 4.2, and (b) to the extent the foregoing clause (a) does not
      apply, Collateral Agent shall deliver such Net Insurance/Condemnation
      Proceeds to Company, and (1) Company and its Subsidiaries may retain and
      apply any portion thereof that is business interruption insurance proceeds
      for working capital purposes or any other purposes not prohibited under
      the Credit Agreements and (2) Company shall, or shall cause one or more of
      its Subsidiaries to, promptly apply such Net Insurance/Condemnation
      Proceeds that are not business interruption insurance proceeds to the
      costs of repairing, restoring, or replacing the assets in respect of which
      such Net Insurance/Condemnation Proceeds were received; provided, however
      that if at any time Senior Agent reasonably determines (A) that Company or
      such Subsidiary is not proceeding diligently with such repair, restoration
      or replacement or that such repair, restoration or replacement cannot be
      completed within 180 days after the receipt by Collateral Agent of such
      Net Insurance/Condemnation Proceeds, Senior Agent may direct Collateral
      Agent, and Company hereby authorizes Senior Agent and Collateral Agent to
      apply such Net Insurance/Condemnation Proceeds as provided in subsection
      4.1(b).

            2.4 AMENDMENTS, MODIFICATIONS, WAIVERS AND RELEASES. Notwithstanding
anything in the Credit Agreements, Collateral Documents and other Credit
Documents to the contrary (but subject to subsection 7.1(c)),

            (a) except in connection with any Enforcement Action, the release of
      the Lien granted in favor of Collateral Agent on all or substantially all
      of the Collateral under the Collateral Documents shall require the prior
      written consent of each Revolver Lender and


                                       20

      each Term Loan Lender; (except that such Lien may be released on all or
      substantially all Collateral to the extent such release is required in
      connection with an Asset Sale or Asset Sales permitted under the Credit
      Agreements); provided however, that, if prior to or concurrently with any
      such release the Revolver Loan Obligations are Paid in Full, then such
      release shall not require any Revolver Lender's consent; and

            (b) except as set forth in subsection 2.4(a), any amendment,
      modification, termination or waiver of, any Collateral Documents shall
      require the prior written consent of (i) until Payment in Full of all
      Revolver Loan Obligations, Requisite Revolver Lenders and (ii) until
      Payment in Full of all Term Loan Obligations, Requisite Term Loan Lenders.

            2.5 AMENDMENTS, MODIFICATIONS AND WAIVERS WITH RESPECT TO CREDIT
DOCUMENTS. Any amendment or modification of, or waiver of compliance with the
terms of any Credit Document, shall (subject to subsection 7.1(c)) be subject to
the following requirements:

            (a) Until (i) the termination of the Term Loan Agreement and the
      Payment in Full of all Term Loan Obligations, without the prior written
      consent of Requisite Term Loan Lenders, and (ii) the termination of the
      Revolver Credit Agreement and the Payment in Full of all Revolver Loan
      Obligations, without the prior written consent of Requisite Revolver
      Lenders, Company shall not, and shall not permit any of its Subsidiaries
      to amend, restate, modify or waive (or make any payment consistent with an
      amendment, restatement, modification or waiver of) any material provision
      of the Management Services and Reimbursement Agreement, the Existing IPP
      Project Guaranties, or the DHC Tax Sharing Agreement, in each case if the
      effect of such amendment, restatement, modification or waiver, together
      with all other amendments, restatements, modifications or waivers made,
      (a) is to impose additional material obligations on, or confer additional
      material rights to the holders thereof (or to other obligees with respect
      thereto) against, Company or any of its Subsidiaries, (b) is otherwise
      adverse to the interests of the Term Loan Lenders in a manner deemed
      material in the judgment of the Term Loan Agents or Requisite Term Loan
      Lenders so notifying Term Loan Agents or Company, or (c) is otherwise
      adverse to the interests of the Revolver Lenders in a manner deemed
      material in the judgment of the Revolver Agent or Requisite Revolver
      Lenders so notifying Revolver Agent or Company.

            (b) Subject to the provisions of subsection 2.4, and until the
      termination of the Term Loan Agreement and the Payment in Full of all Term
      Loan Obligations, without the prior written consent of Requisite Term Loan
      Lenders, Revolver Lenders may not amend, restate, modify or waive (or
      receive any payment consistent with an amendment, restatement,
      modification or waiver of) any material provision of any of the Revolver
      Documents, unless (i) the terms of the Revolver Documents as so amended,
      restated, modified or waived are not more disadvantageous to Company and
      its Subsidiaries and the Term Loan Lenders (in a manner deemed material by
      Term Loan Agent or Requisite Term Loan Lenders so notifying Term Loan
      Agent or Company) than the Revolver Documents in effect on the Closing
      Date (it being understood and agreed that any amendment, restatement,
      modification or waiver having the effect of increasing the amount of, or
      reducing, delaying or waiving any otherwise required reduction in the


                                       21

      amount of, any commitment to extend loans under the Revolver Documents
      shall be deemed to be more disadvantageous for purposes of this clause (i)
      without further notice or other action by Term Loan Agents or Requisite
      Term Loan Lenders), (ii) the aggregate amount of indebtedness and
      additional commitments to extend credit, if any, under the Revolver
      Documents as so amended, restated, modified or waived, do not exceed the
      aggregate amount of the commitments to extend credit in effect under the
      Revolver Documents on the Closing Date, (iii) the obligations under (and
      the Liens securing) such Revolver Documents as so amended, restated,
      modified or waived are subject to this Agreement on terms substantively
      identical to the terms applicable to the obligations in effect under the
      Revolver Documents on the Closing Date, and (iv) Company provides to Term
      Loan Agents reasonable prior advance written notice of such proposed
      amendment, restatement, modification or waiver and copies of all material
      contracts or other agreements being entered into in connection therewith.

            (c) Subject to the provisions of subsection 2.4, and until the
      termination of the Revolver Credit Agreement and the Payment in Full of
      all Revolver Loan Obligations, without the prior written consent of
      Requisite Revolver Lenders, Term Loan Lenders may not amend, restate,
      modify or waive (or receive any payment consistent with an amendment,
      restatement, modification or waiver of) any material provision of any of
      the Term Loan Documents, unless (i) the terms of the Term Loan Documents
      as so amended, restated, modified or waived are not more disadvantageous
      to Company and its Subsidiaries and the Revolver Lenders (in a manner
      deemed material by Revolver Agent or Requisite Revolver Lenders so
      notifying Revolver Agent or Company) than the Term Loan Documents in
      effect on the Closing Date (it being understood and agreed that any
      amendment, restatement, modification or waiver having the effect of
      increasing the amount of, or reducing, delaying or waiving any otherwise
      required reduction in the amount of, any commitment to extend loans under
      the Term Loan Documents shall be deemed to be more disadvantageous for
      purposes of this clause (i), without further notice or other action by
      Revolver Agent or Requisite Revolver Lenders), (ii) the aggregate amount
      of indebtedness and additional commitments to extend credit, if any, under
      the Term Loan Documents as so amended, restated, modified or waived, do
      not exceed the aggregate amount of the commitments to extend credit in
      effect under the Term Loan Documents on the Closing Date plus the amount
      of any Additional Interest Loans and other Term Loans deemed made
      thereunder from time to time pursuant to subsections 2.2B and 2.1A of the
      Term Loan Agreement, respectively, (iii) the obligations under (and the
      Liens securing) such Term Loan Documents as so amended, restated, modified
      or waived are subject to this Agreement on terms substantively identical
      to the terms applicable to the obligations in effect under the Term Loan
      Documents on the Closing Date, and (iv) Company provides to Revolver Agent
      reasonable prior advance written notice of such proposed amendment,
      restatement, modification or waiver and copies of all material contracts
      or other agreements being entered into in connection therewith.

            (d) Each Lender acknowledges and agrees that Borrowers have agreed
      to and are bound by the provisions of subsection 5.12 (Most Favored
      Nations Payments) of each Credit Agreement.


                                       22

                                  SECTION III

            3.1 PRIORITY OF LIENS. Notwithstanding the order or time of
attachment, or the order, time or manner of perfection, or the order or time of
filing or recordation of any document or instrument, or other method of
perfecting a security interest in favor of Collateral Agent in any Collateral,
and notwithstanding any conflicting terms or conditions which may be contained
in any of the Credit Documents, the Secured Parties agree that as among the
Secured Parties, the following Lien priorities shall strictly apply in defining
the respective Lien priorities of each Secured Party in the Collateral:

            (a) first, the Liens upon the Collateral in favor of Collateral
      Agent to the extent securing the Secured Obligations owing from time to
      time to the Collateral Agent, in its capacity as Collateral Agent, to the
      full extent thereof;

            (b) second: the Liens upon the Collateral in favor of Collateral
      Agent to the extent securing, on a pari passu basis, the Secured
      Obligations owing from time to time to the Term Loan Agents and Revolver
      Loan Agent, in their capacities as Term Loan Agents and Revolver Loan
      Agent, respectively, to the full extent thereof;

            (c) third: the Liens upon the Collateral in favor of Collateral
      Agent to the extent securing, on a pari passu basis, (i) the remaining
      Revolver Loan Obligations, and (ii) the Cash Management Obligations, in
      each case to the full extent thereof; and

            (d) fourth: the Liens upon the Collateral in favor of Collateral
      Agent to the extent securing the Term Loan Obligations to the full extent
      thereof.

            3.2 PRIORITIES UNAFFECTED BY ACTION OR INACTION. The Lien priorities
in subsection 3.1 shall not be altered or otherwise affected by any amendment,
modification, supplement, extension, renewal, restatement or refinancing of any
of the Secured Obligations, nor by any action or inaction which Collateral Agent
or any other Secured Party may take or fail to take in respect of the
Collateral.

                                   SECTION IV

            4.1 APPLICATION OF MANDATORY PREPAYMENTS UNDER CREDIT AGREEMENTS AND
NET ASSET SALE PROCEEDS. Notwithstanding anything in the Credit Documents to the
contrary but subject in all respects to subsection 4.2, so long as any Creditor
Obligations are outstanding (including any loans or any commitments to lend):

            (a) Any Mandatory Payments pursuant to subsection 2.4A(iii)(e) of
      the Revolver Credit Agreement and subsection 2.4A(ii)(e) of the Term Loan
      Agreement shall, in each case, be applied first, to the payment of any
      Approved Operating Expenses then due and payable to Management Services
      and Reimbursement Agreement Beneficiaries pursuant to the Management
      Services and Reimbursement Agreement; second, to the extent of any excess
      amounts remaining after application in clause first, to the payment of
      interest then due and payable on the Term Loans pursuant to subsection
      2.2B(ii) of the Term Loan Agreement; third, to the extent of any excess
      amounts remaining after the application described in clauses first and
      second, to repay any


                                       23

      Management Services and Reimbursement Agreement Obligations then due and
      payable; and fourth to the extent of any excess amounts remaining after
      application in clauses first, second and third, to prepay outstanding Term
      Loans.

            (b) Any Mandatory Payments pursuant to subsections 2.4A(iii)(a) -
      (d) of the Revolver Credit Agreement and subsection 2.4A(ii)(a) - (d) of
      the Term Loan Agreement shall, in each case, be applied first, to the
      payment of any Approved Operating Expenses then due and payable to
      Management Services and Reimbursement Agreement Beneficiaries pursuant to
      the Management Services and Reimbursement Agreement, second, to the extent
      of any excess amounts remaining after the application described in clause
      first, (a) to reduce Revolver Loan Exposure in an amount equal to 50% of
      such excess amounts with such reduction in Revolver Loan Exposure to occur
      by repaying outstanding Revolver Loans to the full extent thereof and
      permanently reducing the Revolver Loan Commitments in the full amount of
      the portion of such payment so applied to reduce Revolver Loan Exposure
      (provided, however, that no such application shall reduce the Revolver
      Loan Commitments to the extent that the sum of any Cash On Hand plus the
      amount of Revolver Loan Commitments would be less than $10,000,000 after
      giving effect to such reduction), with any amounts so applied to Revolver
      Loan Exposure but not actually applied to repay Revolver Loans being
      retained by Revolver Borrowers, and (b) to repay any Management Services
      and Reimbursement Agreement Obligations then due and payable and
      outstanding Term Loans in an amount equal to 50% of such excess amounts,
      (with such amount being applied first to such Management Services and
      Reimbursement Agreement Obligations and then to prepay outstanding Term
      Loans); and third, if either (1) no Revolver Loans are outstanding and the
      sum of all Cash On Hand plus the amount of Revolver Loan Commitments is
      less than $10,000,000, or (2) no Management Services and Reimbursement
      Agreement Obligations and no Term Loans are outstanding, but both events
      described in clauses (1) and (2) shall not have occurred, to repay and
      reduce Revolver Loan Exposure by repaying Revolving Loans and permanently
      reducing Revolving Loan Commitment (with any amounts so applied to
      Revolver Loan Exposure but not actually applied to repay Revolver Loans
      being retained by Borrowers) or Management Services and Reimbursement
      Agreement Obligations and Term Loans (with amounts being applied first to
      Management Services and Reimbursement Agreement Obligations and then to
      Term Loans) to the extent required so that both such events shall occur;
      provided that, notwithstanding anything in the foregoing to the contrary,
      to the extent that any Mandatory Payment applied to prepay Term Loans
      pursuant to this subsection 4.1(b) constitutes Net Asset Sale Proceeds, 5%
      of the aggregate amount of such Net Asset Sale Proceeds shall be applied
      to the payment of Prepetition Unsecured Claims Participation Interest
      (provided, that the aggregate cumulative amount of all Net Asset Sale
      Proceeds so applied, when aggregated with all other Aggregate Net Sales
      Proceeds paid or distributed in respect of Prepetition Unsecured Claims
      Participation Interest, shall not exceed $4,000,000) and 95% of such
      amount shall be applied to prepay Term Loans).

            (c) In the event that at the time of receipt by Company or any of
      its Subsidiaries of any Net Asset Sale Proceeds, the Term Loan Obligations
      shall have been Paid in Full and the Prepetition Unsecured Claims
      Participation Interest shall not have been Paid in Full at such time, 5%
      of the aggregate amount of such Net Asset Sale


                                       24

      Proceeds shall be applied to the payment of the Prepetition Unsecured
      Claims Participation Interest until such time as the aggregate amount of
      such Net Asset Sale Proceeds applied to the payment of the Prepetition
      Unsecured Claims Participation Interest when aggregated with all other
      Aggregate Net Sale Proceeds paid or distributed in respect of the
      Prepetition Unsecured Claims Participation Interest, shall total
      $4,000,000.

            (d) All payments of Term Loans pursuant to this subsection 4.1 shall
      made to the Term Loan Agent for distribution to the Term Loan Lenders and
      the Disbursing Agents in accordance with the Term Loan Agreement,
      including subsection 9.25 thereof.

            4.2 APPLICATION OF PROCEEDS OF COLLATERAL, ETC.

            (a) Except as provided in subsection 4.2(b) or 4.2(c) below, upon
      the occurrence and during the continuation of an Event of Default or the
      termination of the Revolver Loan Commitments (other than as a result of
      any voluntary termination of Revolver Loan Commitments by Revolver
      Borrowers pursuant to subsection 2.4A(ii) of the Revolver Credit
      Agreement), if requested by Requisite Revolver Lenders with respect to any
      Revolver Event of Default or termination of Revolver Loan Commitments, or
      if requested by Requisite Term Loan Lenders with respect to any Term Loan
      Event of Default, (1) all Mandatory Payments or other payments received by
      any Agent or other Creditor Party on account of the Creditor Obligations,
      whether from any Loan Party or otherwise, shall promptly be delivered to
      Collateral Agent and upon receipt by Collateral Agent, applied by
      Collateral Agent against the Creditor Obligations and (2) all Proceeds
      received by Collateral Agent in respect of any sale of, collection from,
      or other realization upon all or any part of the Collateral or other
      Enforcement Action may, in the discretion of Senior Agent upon written
      direction to Collateral Agent, be held by Collateral Agent as Collateral
      for, and/or (then or at any time thereafter) applied in full or in part by
      Collateral Agent against, the applicable Creditor Obligations, in each
      case under clauses (1) and (2) in the following order of priority:

                  (i) First, to the payment of the costs and expenses of the
      exercise of rights and remedies and such sale, collection or other

      connection therewith (including for reasonable cost, fees and expenses of
      counsel and other professionals and agents retained by the Collateral
      Agent) and all amounts for which Collateral Agent is entitled to
      compensation, reimbursement and indemnification under any Credit Document
      and any other amounts then owing to Collateral Agent, in its capacity as
      Collateral Agent, pursuant to the Collateral Documents;

                  (ii) Second, to the extent proceeds remain after application

                                       25

                  (iii) Third, to the extent proceeds remain after application

      Operating Expenses until all Approved Operating Expenses have been Paid in
      Full;

                  (iv) Fourth, to the extent proceeds remain after application
      as described in clauses (i) through (iii) above, pro rata among the

      Obligations when due under the Term Loan Agreement.


                                       26


            (c) Until Proceeds are applied as set forth in this subsection 4.2,
      Collateral Agent shall hold such Proceeds in its custody in accordance
      with its regular procedures for handling deposited funds.

            (d) Payments by Collateral Agent to the Revolver Lenders in respect
      of the Obligations shall be made to the Revolver Agent for distribution to
      the Revolver Lenders in accordance with the Revolver Credit Agreement and
      this Agreement; payments by Collateral Agent to the Term Loan Lenders in
      respect of the Obligations shall be made to the Term Loan Agent for
      distribution to the Term Loan Lenders and the Disbursing Agents in
      accordance with the Term Loan Agreement (including subsection 9.25 of the
      Term Loan Agreement) and this Agreement; any payments in respect of
      Approved Operating Expenses shall be made to such Persons as shall be
      directed in writing by Company pursuant to an Officer's Certificate
      delivered pursuant to subsection 5.1(c); any payments in respect of any
      Management Services and Reimbursement Agreement Obligations shall be paid
      to Covanta, for distribution to the applicable Management Services and
      Reimbursement Agreement Beneficiary; payments in respect of any
      Prepetition Unsecured Claims Participation Interest shall be paid to
      Prepetition Unsecured Claims Agent for distribution to the holders of the
      Prepetition Unsecured Claims Participation Interest; and payments in
      respect of the Cash Management Obligations shall be made to Cash
      Management Bank for the benefit of Cash Management Bank.

            (e) In the event that any Creditor Party shall receive any
      Distribution that such Creditor Party is not entitled to receive or retain
      under the provisions of this Agreement (in such capacity, each, a "JUNIOR
      CREDITOR"), such Junior Creditor shall hold any such Distribution so
      received in trust for the benefit of the holders of other Creditor
      Obligations with the right to receive such Distribution under the
      provisions of this Agreement (in such capacity, each, a "SENIOR CREDITOR")
      and shall segregate such Distribution from other assets held by such
      Junior Creditor; and shall forthwith turn over such Distribution (without
      liability for interest thereon, but with any appropriate endorsements or
      assignments, if necessary) to the holders of, or to Collateral Agent for
      the benefit of the holders of, such Creditor Obligations in the form
      received (with any appropriate endorsement or assignment, if necessary) to
      be distributed in accordance with subsection 4.1 or 4.2, as applicable,
      and applied to such Creditor Obligations. In the event of a failure of any
      Junior Creditor to make any such endorsement or assignment to Collateral
      Agent or Senior Creditors, as the case may be, Collateral Agent and such
      Senior Creditors are hereby irrevocably authorized on behalf of such
      Junior Creditor to make such endorsement or assignment, as applicable. For
      the avoidance of doubt, the provisions of this Agreement regarding Junior
      Creditors and Senior Creditors apply regardless of whether or not a Junior
      Creditor or Senior Creditor is a Secured Party.

            (f) No payment or distribution to any Senior Creditor pursuant to
      the provisions of this Agreement shall entitle the applicable Junior
      Creditor or Junior Creditors to exercise any right of subrogation in
      respect thereof until (i) all Creditor Obligations of such Senior
      Creditors shall have been indefeasibly Paid in Full, or (ii) all of such
      Senior Creditors have consented in writing to the taking of such action.
      With respect to any subrogation claims, each Junior Creditor hereby (to
      the extent permitted by


                                       27

      applicable law) waives, releases and discharges any and all rights,
      claims, causes of action, liabilities, claims and demands, in law or
      equity, which such Junior Creditor has had, now has, or may in the future
      have, arising out of or relating directly or indirectly to the taking or
      not taking of any act or proceeding or not proceeding with any action
      which the Senior Creditors (or that representatives) may take in an effort
      to collect in respect of the Creditor Obligations owed to such Senior
      Creditors.

            (g) In furtherance of, and without limiting, the priority provisions
      set forth in this subsection 4.2, but subject to the applicable voting
      provisions set forth in subsection 2.2, each Secured Party agrees that, in
      order to enable Collateral Agent to enforce its rights hereunder in any
      Bankruptcy Proceeding, Collateral Agent is hereby irrevocably authorized
      and empowered in its sole and absolute discretion to receive and collect
      any and all dividends or other payments or disbursements made on account
      of Collateral Agent's Lien on the Collateral in whatever form the same may
      be paid or issued and to apply the same on account of any such Creditor
      Obligations in accordance with the provisions of the Credit Documents and
      this Agreement. At any time, including but not limited to during any
      Bankruptcy Proceeding, Collateral Agent and each other Party will refrain
      from taking any action which would contest or challenge in any
      administrative, legal or equitable action or otherwise the validity or
      enforceability of the terms of this Agreement, including the priority
      provisions contained in subsection 4.1 and this subsection 4.2 and the
      Lien priority provisions contained in subsection 3.1.

            (h) Each Secured Party hereby covenants and agrees that (i) such
      Secured Party will not accept from any Person on behalf of the Borrowers
      any guarantee (a "THIRD-PARTY GUARANTY") of any Obligations unless such
      guarantor simultaneously guarantees the payment of all Secured Obligations
      owed to each of the other Secured Parties (or, if such Third-Party
      Guaranty guarantees only a portion of the Obligations owing to such
      Secured Party, such Secured Party will not accept such Third-Party
      Guaranty unless such guarantor simultaneously guarantees the same
      proportion of Obligations owing to the other Secured Parties), and (ii)
      such Secured Party will not take, accept or obtain any security interest
      in, or lien or encumbrance upon, any assets of any of the Borrowers or any
      Subsidiary or Affiliate thereof or any other Person to secure the payment
      and performance of the Obligations unless the Collateral Agent, for the
      benefit of all Secured Parties, is granted a pari passu security interest
      in, or lien upon, such assets, in either case, pursuant to documents in
      form and substance satisfactory to the Revolver Agent and Term Loan Agent.

            (i) Each Junior Creditor hereby waives any rights it may have under
      applicable law to assert the doctrine of marshalling or to otherwise
      require Collateral Agent or any Senior Creditors to marshal any property
      of the Loan Parties or any of their respective Affiliates for the benefit
      of such Junior Creditors.

            (j) All payments of Term Loan Obligations pursuant to this
      subsection 4.2 (including Superpriority Term Loan Obligations) shall be
      made to the Term Loan Agent for distribution to the Term Loan Lenders and
      the Disbursing Agents in accordance with the Term Loan Agreement,
      including subsection 9.25 thereof.



                                       28

                                   SECTION V

      such information.

            (b) Term Loan Agent agrees to promptly from time to time to (i)

      payment made pursuant to the Management Services and Reimbursement
      Agreement and received by any Management Services and Reimbursement
      Agreement Beneficiary and (C) the outstanding amount of, and applicable
      recipients of, any Approved Operating Expenses as at any date as
      Collateral Agent may specify, and, in each case, Collateral Agent shall be

                                       29

                                   SECTION VI

            6.1 DISCLAIMERS, SUPPLEMENTAL COLLATERAL AGENT, INDEMNITY, ETC.

            (a) Collateral Agent shall have no duties or responsibilities except
      those expressly set forth in this Agreement and the Collateral Documents
      and Collateral Agent shall not by reason of this Agreement or the
      Collateral Documents be a trustee for any Party or have any other
      fiduciary obligation to any Party. Collateral Agent shall not be
      responsible to any Party for any recitals, statements, representations or
      warranties contained in this Agreement or any other Credit Document or in
      any certificate or other document referred to or provided for in, or
      received by any of them under, this Agreement or any other Credit
      Document, or for the value, validity, effectiveness, genuineness,
      enforceability or sufficiency of this Agreement or any other Credit
      Document or any other document referred to or provided for therein or any
      Lien under the Collateral Documents or the perfection or priority of any
      such Lien or for any failure by any Loan Party to perform any of its
      respective obligations this Agreement or any other Credit Document.
      Collateral Agent may exercise such powers, rights and remedies and perform
      such duties by or through its Affiliates, agents or employees.

            (b) Neither Collateral Agent nor any of its officers, directors,
      employees or agents shall be liable to any Parties for any action taken or
      omitted by Collateral Agent under or in connection with this Agreement or
      any of the Collateral Documents or other Credit Documents except to the
      extent caused by Collateral Agent's gross negligence or willful
      misconduct. Collateral Agent shall be entitled to refrain from any act or
      the taking of any action (including the failure to take an action) in
      connection with this Agreement or any of the Collateral Documents or other
      Credit Documents or from the exercise of any power, discretion or
      authority vested in it hereunder or thereunder unless and until Collateral
      Agent shall have received instructions in respect thereof from Requisite
      Obligees (or such other Secured Parties as may be required to give such
      instructions under subsection 2.4(a)) and, upon receipt of such
      instructions from Requisite Obligees (or such other Secured Parties, as
      the case may be), Collateral Agent shall be entitled to act or (where so
      instructed) refrain from acting, or to exercise such power, discretion or
      authority, in accordance with such instructions. Without prejudice to the
      generality of the foregoing, (i) Collateral Agent shall be entitled to
      rely, and shall be fully protected in relying, upon any communication,
      instrument or document believed by it to be genuine and correct and to
      have been signed or sent by the proper person or persons, and shall be
      entitled to rely and shall be protected in relying on opinions and
      judgments of attorneys (who may be attorneys for Company and its
      Subsidiaries), accountants, experts and other professional advisors
      selected by it; and (ii) no Party shall have any right of action
      whatsoever against an Agent as a result of Collateral Agent acting or
      (where so instructed) refraining from acting under this Agreement or any
      of the other Collateral Documents or other Credit Documents in accordance
      with the instructions of Requisite Obligees (or such other Secured Parties
      as may be required to give such instructions under subsection 2.4(a)).

            (c) It is the purpose of this Agreement and the Collateral Documents
      and other Credit Documents that there shall be no violation of any law of
      any jurisdiction


                                       30

      denying or restricting the right of banking corporations or associations
      to transact business as agent or trustee in such jurisdiction. It is
      recognized that in case of litigation under this Agreement or any of the
      Collateral Documents or other Credit Documents, and in particular in case
      of the enforcement of any of the Collateral Documents, or in case
      Collateral Agent deems that by reason of any present or future law of any
      jurisdiction it may not exercise any of the rights, powers or remedies
      granted herein or in any of the other Collateral Documents or take any
      other action which may be desirable or necessary in connection therewith,
      it may be necessary that Collateral Agent appoint an additional individual
      or institution as a separate trustee, co-trustee, collateral agent or
      collateral co-agent (any such additional individual or institution being
      referred to herein individually as a "SUPPLEMENTAL COLLATERAL AGENT" and
      collectively as "SUPPLEMENTAL COLLATERAL AGENTS").

            In the event that Collateral Agent appoints a Supplemental
      Collateral Agent with respect to any Collateral, (i) each and every right,
      power, privilege or duty expressed or intended by this Agreement or any of
      the other Collateral Documents to be exercised by or vested in or conveyed
      to Collateral Agent with respect to such Collateral shall be exercisable
      by and vest in such Supplemental Collateral Agent to the extent, and only
      to the extent, necessary to enable such Supplemental Collateral Agent to
      exercise such rights, powers and privileges with respect to such
      Collateral and to perform such duties with respect to such Collateral, and
      every covenant and obligation contained in the Collateral Documents and
      necessary to the exercise or performance thereof by such Supplemental
      Collateral Agent shall run to and be enforceable by either Collateral
      Agent or such Supplemental Collateral Agent, and (ii) the provisions of
      this Agreement that refer to Collateral Agent shall inure to the benefit
      of such Supplemental Collateral Agent and all references herein to
      Collateral Agent shall be deemed to be references to Collateral Agent
      and/or such Supplemental Collateral Agent, as the context may require.

            Should any instrument in writing from any Loan Party be required by
      any Supplemental Collateral Agent so appointed by Collateral Agent for
      more fully and certainly vesting in and confirming to him or it such
      rights, powers, privileges and duties, such Loan Party shall execute,
      acknowledge and deliver any and all such instruments promptly upon request
      by Collateral Agent. In case any Supplemental Collateral Agent, or a
      successor thereto, shall die, become incapable of acting, resign or be
      removed, all the rights, powers, privileges and duties of such
      Supplemental Collateral Agent, to the extent permitted by law, shall vest
      in and be exercised by Collateral Agent until the appointment of a new
      Supplemental Collateral Agent.

            (d) Each Lender ratably in accordance with the amount of the
      Creditor Obligations of such Lenders, severally agrees that it shall
      indemnify Collateral Agent and the officers, directors, employees, agents,
      attorneys, professional advisors and affiliates of Collateral Agent to the
      extent that any such Person is neither reimbursed by any Loan Party under
      any Loan Document nor reimbursed out of any Proceeds pursuant to clause
      First of subsection 4.2(a), for and against any and all liabilities,
      obligations, losses, damages, penalties, actions, judgments, suits, costs,
      expenses (including counsel fees and disbursements and fees and fees and
      disbursements of any advisor engaged by Collateral Agent) or disbursements
      of any kind and nature whatsoever which may be imposed on,


                                       31

      incurred by or asserted against Collateral Agent or any such Person
      exercising the powers, rights and remedies of a Collateral Agent or
      performing duties of a Collateral Agent hereunder or under the other
      Collateral Documents or in any way relating to or arising out of this
      Agreement, any Collateral Document or any other Credit Document or any
      other documents contemplated hereby or thereby or referred to therein or
      the transactions contemplated hereby or thereby or the enforcement of any
      of the terms of any thereof; provided, however, that no Lender shall be
      liable for any of the foregoing to the extent they arise from the gross
      negligence or willful misconduct of Collateral Agent as determined by a
      final judgment of a court of competent jurisdiction. No Revolver Agent or
      Term Loan Agent shall have any liability to any Party under this
      subsection 6.1(d). Obligations of Non-Confirming Holders and Disbursing
      Agents pursuant to this subsection 6.1(d) shall be subject to the
      provisions of subsection 9.25 of the Term Loan Agreement.

            (e) The agency hereby created shall in no way impair or affect any
      of the rights and powers of, or impose any duties or obligations upon,
      Collateral Agent in its individual capacity as a Revolver Agent, Term Loan
      Agent or Term Loan Lender, as the case may be, hereunder or under any
      Credit Document. With respect to its participation in the Revolver Loan
      Obligations or Term Loan Obligations, Collateral Agent shall have the same
      rights and powers hereunder as any other Secured Party and may exercise
      the same as though it were not performing the duties and functions
      delegated to it hereunder. Collateral Agent and its Affiliates may accept
      deposits from, lend money to, acquire equity interests in and generally
      engage in any kind of commercial banking, investment banking, trust,
      financial advisory or other business with Company or any of its Affiliates
      as if it were not performing the duties specified herein, and may accept
      fees and other consideration from any Loan Party for services in
      connection with this Agreement and otherwise without having to account for
      the same to Creditor Parties.

            (f) Collateral Agent may deem and treat the payee of any promissory
      note or other evidence of indebtedness relating to the Creditor
      Obligations as the owner thereof for all purposes hereof unless and until
      a written notice of the assignment or transfer thereof, signed by such
      payee and in form satisfactory to Collateral Agent, shall have been filed
      with Collateral Agent. Any request, authority or consent of any Person who
      at the time of making such request or giving such authority or consent is
      the holder of any such note or other evidence of indebtedness shall be
      conclusive and binding on any subsequent holder, transferee or assignee of
      such note or other evidence of indebtedness and of any note or notes or
      other evidences of indebtedness issued in exchange therefor.
      Notwithstanding anything to the contrary contained in the Term Loan
      Documents, the Revolver Documents or Management Services and Reimbursement
      Agreement, (i) no assignment or transfer (including, without limitation, a
      refinancing or replacement) of any interest of (A) any Revolver Lender in
      the Revolver Loan Exposure or Revolver Loans (including pursuant to any
      refinancing, restatement, replacement or extension of the Revolver Credit
      Agreement not prohibited hereunder), or (B) any interest of any Term Loan
      Lender in the Term Loan or the Term Loans (including pursuant to any
      refinancing, restatement, replacement or extension of the Term Loan
      Agreement not prohibited hereunder), may in any case be made unless the
      transferee, assignee or any Person who became a lender pursuant to a
      refinancing, restatement, replacement or


                                       32

      extension of the Term Loan Agreement or Revolver Credit Agreement, as the
      case may be, executes an Assumption Agreement in the form of Annex 1
      hereto, (ii) no appointment (A) of any successor Revolver Agent under the
      Revolver Credit Agreement (including pursuant to any refinancing,
      restatement, replacement or extension of the Revolver Credit Agreement not
      prohibited hereunder), (B) any successor Term Loan Agent or Term Loan
      Documentation Agent under the Term Loan Agreement (including pursuant to
      any refinancing, restatement, replacement or extension of the Term Loan
      Agreement not prohibited hereunder), or (C) any successor Prepetition
      Unsecured Claims Agent may in any case be made unless the successor
      executes an Assumption Agreement in the form of Annex 1 hereto and (iii)
      no Management Services and Reimbursement Agreement Beneficiary may assign
      or transfer any of its interest in the Management Services and
      Reimbursement Agreement without the prior written consent of Requisite
      Revolver Lenders and Requisite Term Loan Lenders.

            (g) Except as expressly provided herein and in the Collateral
      Documents, Collateral Agent shall have no duty to take any affirmative
      steps with respect to the collection of amounts payable in respect of the
      Collateral. Collateral Agent shall incur no liability to any Party as a
      result of any sale of any Collateral at any private sale.

            (h) Collateral Agent may resign at any time by giving at least 30
      days' notice thereof to the Parties and Collateral Agent may be removed as
      Collateral Agent at any time by Requisite Obligees. In the event of such
      resignation or removal of Collateral Agent, Requisite Obligees shall
      thereupon have the right to appoint a successor Collateral Agent. If no
      successor Collateral Agent shall have been so appointed by Requisite
      Obligees within 30 days after the resigning Collateral Agent's giving
      notice of its intention to resign, then the resigning Collateral Agent may
      appoint, on behalf of Secured Parties, a successor Collateral Agent and
      Company hereby agrees to pay to such successor Collateral Agent, in
      addition to any other amounts payable to Collateral Agent hereunder and
      under the Collateral Documents, such reasonable annual fees in such
      amounts and at such times as may be requested by such successor Collateral
      Agent.

            (i) Upon the acceptance of any appointment as Collateral Agent
      hereunder by a successor Collateral Agent, such successor Collateral Agent
      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 Collateral Documents. After any retiring or removed
      Collateral Agent's resignation or removal hereunder as Collateral Agent,
      the provisions of this subsection 6.1 shall continue in effect for its
      benefit in respect of any actions taken or omitted to be taken by it while
      it was acting as Collateral Agent.

            (j) In no event shall Collateral Agent or any Secured Party be
      liable or responsible for any funds or investments of funds held by any
      Loan Party.

            (k) Upon the proposed sale or other disposition of any Collateral
      that is permitted by the Credit Agreements and is not prohibited by
      subsection 2.4(a) or has been consented to by Requisite Obligees in
      connection with an Enforcement Action, and for which a Loan Party desires
      to obtain a security interest release from Collateral Agent,


                                       33

      such Loan Party shall deliver an Officer's Certificate to Collateral
      Agent, Revolver Loan Agent and Term Loan Agent (i) stating that the
      Collateral or the Capital Stock subject to such disposition is being sold
      or otherwise disposed of in compliance with the terms hereof and of the
      Credit Agreements and (ii) specifying the Collateral or Capital Stock
      being sold or otherwise disposed of in the proposed transaction. Upon the
      receipt of such Officer's Certificate, Collateral Agent shall, at Loan
      Parties' joint and several expense, so long as Senior Agent has not
      informed Collateral Agent that it (a) has reason to believe that the facts
      stated in such Officer's Certificate are not true and correct and (b) if
      the sale or other disposition of such item of Collateral or Capital Stock
      constitutes an Asset Sale (as defined in each Credit Agreement) has not
      received evidence satisfactory to it that arrangements satisfactory to it
      have been made for delivery of the Net Asset Sale Proceeds (as defined in
      each Credit Agreement) if and as required by subsection 2.4 of the
      respective Credit Agreement, execute and deliver such releases of its
      security interest in such Collateral as may be reasonably requested by
      such Loan Party. In the event of any conflict or inconsistency between
      this subsection 6.1(k) and the terms of any other Credit Document, the
      terms of this Agreement shall prevail.

                                  SECTION VII

            7.1 MISCELLANEOUS.


            (a) All notices and other communications provided for herein shall
      be in writing and may be personally served, or sent by telefacsimile or

      provided in this clause (a)) and shall be deemed to have been given (i)
      when delivered in person or by courier service, (ii) upon receipt of
      telefacsimile in complete and legible form, (iii) three Business Days
      after deposit in the United States mail with postage prepaid and properly
      addressed, or (iv) in the case of electronic mail to the extent provided
      in this clause (a); provided that notices to Collateral Agent shall not be
      effective until received. For the purposes hereof, the addresses of the
      parties hereto (until notice of a change thereof is delivered as provided
      in this subsection 7.1(a)) shall be as set forth under each party's name
      on the signature pages (including acknowledgments) hereof. Notices and
      other communications to the Lenders, Revolver Agent and Term Loan Agents
      hereunder may be delivered or furnished by electronic communication
      (including e-mail and Internet or intranet websites) pursuant to
      procedures approved by Collateral Agent. Collateral Agent or any Borrower
      may, in its discretion, agree to accept notices and other communications
      to it hereunder by electronic communications pursuant to procedures
      approved by it, provided that approval of such procedures may be limited
      to particular notices or communications.

            (b) Subject to Section 7.1(c), no amendment, modification,
      termination or waiver of any provision of this Agreement, and no consent
      to any departure by any Party therefrom, shall in any event be effective
      without the written concurrence of Requisite Revolver Lenders and
      Requisite Term Loan Lenders; provided that (i) no such amendment,
      modification, termination or waiver shall, without the consent of each
      Secured Party with Secured Obligations directly affected thereby, amend,
      modify, terminate or waive, or have the effect of amending, modifying,
      terminating or waiving, the definition of "Requisite Obligees" or
      subsection 3.1, (ii) no such amendment,


                                       34

      modification, termination or waiver shall, without the consent of each
      Creditor Party (other than Prepetition Unsecured Claims Agent) with
      Creditor Obligations directly affected thereby, amend, modify, terminate
      or waive, or have the effect of amending, modifying, terminating or
      waiving (A) subsection 4.1 or 4.2 or this subsection 7.1(b), or (B) any
      other provision of this Agreement in a manner that would impose any
      additional material obligations on such Creditor Party or prejudice any
      material rights or remedies of such Creditor Party, (iii) no amendment,
      modification, termination or waiver of any provision of subsection 2.1 or
      2.2 or Section 5 or 6 or of any other provision of this Agreement which,
      by its terms, expressly requires the approval or concurrence of Collateral
      Agent shall be effective without the written concurrence of Collateral
      Agent; and (iv) no such amendment, modification, termination or waiver of
      this Agreement shall materially increase or materially adversely affect
      obligations of any Loan Party or adversely affect any rights of a Loan
      Party under the other Credit Documents in each case without such Loan
      Party's prior written consent; provided, further, that, without the prior
      written consent of Prepetition Unsecured Claims Agent, no such amendment,
      modification, termination or waiver shall (x) modify or otherwise alter in
      any manner adverse to the holders of the Prepetition Unsecured Claims
      Participation Interest the right of such holders to receive Proceeds in
      the amount and order of priority and under the circumstances described in
      subsections 4.1(b), 4.1(c) and 4.2(a), as in effect on the date hereof,
      (y) impose any additional obligation on Prepetition Unsecured Claims Agent
      or (z) amend, modify, terminate or waive, or have the effect of amending,
      modifying, terminating or waiving the rights of Prepetition Unsecured
      Claims Agent under this subsection 7.1(b). To the extent (if any) the
      provisions of this Agreement are inconsistent with the provisions set
      forth in any Credit Agreement in any particular circumstance, then the
      provisions set forth in this Agreement shall prevail to the extent
      necessary to eliminate or avoid such inconsistency in such circumstance;
      provided further, however, that no concurrence of any Lender or Lenders
      shall be required (I) for any amendment, modification, termination or
      waiver of any provision of subsection 7.1(c) or any other section or
      provision herein that only affects the rights and obligations of Debenture
      Disbursing Agent under this Agreement, so long as Term Loan Agents and
      Term Loan Borrowers (and, after execution hereof, the Debenture Disbursing
      Agent) approve such amendment, modification, termination or waiver; and
      (II) for any amendment, modification, termination or waiver of any
      provision of subsection 7.1(c) or any other section or provision that only
      affects the rights and obligations of Allowed Class 6 Disbursing Agent
      under this Agreement, so long as Term Loan Agents and Term Loan Borrowers
      (and, after execution hereof, the Allowed Class 6 Disbursing Agent)
      approve such amendment, modification, termination or waiver.

            (c) All Term Loans that would otherwise be distributed on the
      Allowed Class 6 Closing Date or the Determination Date (if the Allowed
      Class 6 Closing Date shall have occurred prior to the Determination Date)
      on account of Allowed Class 6 Interests shall be held on such date by the
      Allowed Class 6 Disbursing Agent; and all Term Loans that would otherwise
      be distributed on the Debenture Closing Date or the Determination Date (if
      the Debenture Closing Date shall have occurred prior to the Determination
      Date) on account of 9.25% Debentures shall be held on such date by the
      Debenture Disbursing Agent. For so long as Debenture Disbursing Agent or
      Allowed Class 6 Disbursing Agent holds Term Loans (subject to subsection
      9.25 of the Term Loan


                                       35

      Agreement) that would otherwise have been Term Loans deemed made directly
      by or distributed directly to Non-Confirming Holders, such Disbursing
      Agent shall be the Term Loan Lender of record with respect to such Term
      Loan Loans held by it (and the corresponding Term Loan Commitments and
      Term Loan Exposure), except that no Disbursing Agent shall be deemed a
      "Term Loan Lender", "Creditor Party" or "Secured Party" for purposes of
      voting on any matters (including the granting of any approvals, consents
      or waivers) with respect to this Agreement; provided, however, that this
      clause (c) shall not be construed as permitting, without the prior written
      consent of the relevant Non-Confirming Holder, (a) modification of the
      rights, duties or obligations under the this Agreement (other than with
      respect to voting on any matters) of any Disbursing Agent or of the
      Non-Confirming Holders for whom such Disbursing Agent serves as record
      Term Loan Lender, without concurrent and corresponding modification of the
      rights, duties and obligations of Term Loan Lenders other than such
      Disbursing Agent, (b) this Agreement to be modified to require that any
      Disbursing Agent or Non-Confirming Holder make any loan, advance or other
      extension of credit to, or incur any additional obligation to, any
      Borrower or any other Person on or after the Closing Date, other than the
      Term Loans and monetary obligations pursuant to the provisions of the Term
      Loan Documents in effect on the Closing Date, or (c) modification of the
      provisions of this clause (c) in a manner that is adverse in any material
      respect to the Disbursing Agents or the Non-Confirming Holders. For the
      avoidance of any doubt, the Term Loans, Term Loan Commitments and Term
      Loan Exposure of each Disbursing Agent shall be excluded in calculating
      the number or percentage of Term Loans, Term Loan Commitments, Term Loan
      Exposure and/or Term Loan Lenders whose votes are required and obtained
      (or not obtained, as the case may be) for purposes of voting on any
      matters with respect to this Agreement.

            Any Non-Confirming Holder that executes and delivers to Collateral
      Agent, in accordance with subsection 9.25 of the Term Loan Agreement, an
      acknowledgment and counterpart, in substantially the form of Annex 2
      hereto, shall cease to be a Non-Confirming Holder and shall thereupon
      become a "Term Loan Lender", "Creditor Party" and "Secured Party" for all
      purposes hereunder and such Non-Confirming Holder holding a Term Loan and
      Term Loan Commitments in amounts equal to the amounts so confirmed by the
      Debenture Disbursing Agent, the Debenture Disbursing Agent shall be deemed
      to have assigned such Term Loan and Term Loan Commitment to such Term Loan
      Lender on such date for all purposes of this Agreement (without having to
      execute an Assumption Agreement in the form of Annex 1 hereto
      notwithstanding subsection 6.1(f)).

            Nothing in this Agreement, express or implied, shall be construed to
      confer upon any Non-Confirming Holder that does not become a Term Loan
      Lender any legal or equitable right, remedy or claim under or by reason of
      this Agreement; Collateral Agent shall not have, by reason of this
      Agreement, a fiduciary relationship in respect of any Disbursing Agent or
      any Non-Confirming Holder; and nothing in this Agreement, expressed or
      implied, is intended to or shall be so construed as to impose upon
      Collateral Agent any obligations to any Disbursing Agent or any
      Non-Confirming Holder in respect of this Agreement except as expressly set
      forth herein.



                                       36

            Subject to the occurrence of the Debenture Closing Date, the
      Debenture Disbursing Agent shall execute and deliver this Agreement and
      the Term Loan Agreement as the agent for the Non-Confirming Holders on
      account of the 9.25% Debentures under the Approved Plan of Reorganization
      and the Confirmation Order. Subject to the occurrence of the Allowed Class
      6 Closing Date, the Allowed Class 6 Disbursing Agent shall execute and
      deliver this Agreement and the Term Loan Agreement as the agent for the
      Non-Confirming Holders on account of the Allowed Class 6 Claims under the
      Approved Plan of Reorganization and the Confirmation Order.

            (d) Subject to the provisions of subsection 6.1(f), this Agreement
      shall be binding upon and inure to the benefit of Collateral Agent and
      each other Party and, other than with respect to the Management Services
      and Reimbursement Agreement Beneficiaries (except pursuant to a merger of
      Covanta otherwise permitted pursuant to the Credit Agreements), their
      respective successors and assigns, including successors to Revolver Agents
      and Revolver Lenders under the Revolver Loan Documents, Term Agents and
      Term Loan Lenders under the Term Loan Documents and Prepetition Unsecured
      Claims Agent.

            (e) This Agreement may be executed in any number of counterparts,
      all of which taken together shall constitute one and the same instrument,
      and any of the parties hereto may execute this Agreement by signing any
      such counterpart.

            (f) This Agreement shall become effective on the Closing Date and
      upon the execution of this Agreement by each Loan Party, each Term Loan
      Lender, each Revolver Lender, each Term Loan Agent, Revolver Agent, each
      Management Services and Reimbursement Agreement Beneficiary, Prepetition
      Unsecured Claims Agent and Collateral Agent.

            (g) The Collateral Agent may deem and treat the Secured Parties as
      the "Secured Parties" for all purposes hereof unless and until a notice of
      the assignment or transfer of any interest held by such Party shall have
      been filed with the Collateral Agent in accordance with subsection 6.1(f).
      The Company agrees that it will advise the Collateral Agent of any
      transfer by any Secured Party of any Revolver Loan Exposure or Term Loan
      Exposure held by such Secured Party and will, from time to time upon
      request of the Collateral Agent, deliver a list to the Collateral Agent
      (which shall be distributed by the Collateral Agent to each Secured Party)
      setting forth, for the Revolver Loan Exposure, Term Loan Exposure and
      Management Services and Reimbursement Agreement Obligations, the unpaid
      principal amount and holder thereof. The Collateral Agent may rely on such
      list unless, after the distribution thereof, the Collateral Agent is
      notified by a Secured Party that such information as set forth on such
      list is inaccurate.

            (h) ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST ANY OF THE PARTIES
      ARISING OUT OF OR RELATING TO THIS AGREEMENT MAY BE BROUGHT IN ANY STATE
      OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE STATE OF NEW YORK AND BY

      RELEASES AND AGREES NOT TO SUE UPON ANY SUCH CLAIM FOR ANY SUCH DAMAGES,
      WHETHER OR NOT ACCRUED AND WHETHER OR NOT KNOWN OR SUSPECTED TO EXIST IN
      ITS FAVOR.

      GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE
      INTERNAL LAWS OF THE STATE OF NEW YORK (INCLUDING SECTION 5-1401 OF THE
