Parity Lien Obligations granted on the Collateral or of any Liens securing the
First Lien Obligations granted on the Collateral and notwithstanding any
provision of the UCC, or any other applicable law or the Parity Lien Documents
or any defect or deficiencies in, or failure to perfect, the Liens securing the
First Lien Obligations or any other circumstance whatsoever, the Parity Lien
Collateral Agent, on behalf of itself and the Parity Lien Claimholders, hereby
agrees that:

            (a) any Lien on the Collateral securing any First Lien Obligations
now or hereafter held by or on behalf of the First Lien Collateral Agent or any
First Lien Claimholders or any agent or trustee therefor, regardless of how
acquired, whether by grant, possession, statute, operation of law, subrogation
or otherwise, shall be senior in all respects and prior to any Lien on the
Collateral securing any Parity Lien Obligations;

            (b) any Lien on the Collateral securing any Parity Lien Obligations
now or hereafter held by or on behalf of the Parity Lien Collateral Agent, any
Parity Lien Claimholders or any agent or trustee therefor regardless of how
acquired, whether by grant, possession, statute, operation of law, subrogation
or otherwise, shall be junior and subordinate in all respects to all Liens on
the Collateral securing any First Lien Obligations. All Liens on the Collateral
securing any First Lien Obligations shall be and remain senior in all respects
and prior to all Liens on the Collateral securing any Parity Lien Obligations
for all purposes, whether or not such Liens securing any First Lien Obligations
are subordinated to any Lien securing any other obligation of the Company, any

acquired, whether by grant, possession, statute, operation of law, subrogation
or otherwise, shall be shared Equally and Ratably among the Parity Lien
Claimholders.

            2.2 Prohibition on Contesting Liens. Each of the Parity Lien
Collateral Agent, for itself and on behalf of each Parity Lien Claimholder, and
the First Lien Collateral Agent, for itself and on behalf of each First Lien
Claimholder, agrees that it will not (and hereby waives any right to) contest or
support any other Person in contesting, in any proceeding (including any
Insolvency or Liquidation Proceeding), the perfection, priority, validity or
enforceability of a Lien held by or on behalf of any of the First Lien

                                       14
<PAGE>

Claimholders in the First Lien Collateral or by or on behalf of any of the
Parity Lien Claimholders in any of the Parity Lien Collateral, as the case may
be, or the provisions of this Agreement; provided that nothing in this Agreement
shall be construed to prevent or impair the rights of the First Lien Collateral
Agent or any First Lien Claimholder to enforce this Agreement, including the
provisions of this Agreement relating to the priority of the Liens securing the
First Lien Obligations as provided in Sections 2.1 and 3.1.

            2.3 No New Liens. So long as the Discharge of First Lien Obligations
has not occurred, whether or not any Insolvency or Liquidation Proceeding has
been commenced by or against the Company or any other Grantor, the parties
hereto agree that the Company shall not, and shall not permit any other Grantor
to:

            (a) grant or permit any additional Liens on any asset or property to
secure any Parity Lien Obligation unless it has granted or concurrently grants a
Lien on such asset or property to secure the First Lien Obligations; or

            (b) grant or permit any additional Liens on any asset or property to
secure any First Lien Obligations unless it has granted or concurrently grants a
Lien on such asset or property to secure the Parity Lien Obligations.

To the extent that the foregoing provisions are not complied with for any
reason, without limiting any other rights and remedies available to the First
Lien Collateral Agent and/or the First Lien Claimholders, the Parity Lien
Collateral Agent, on behalf of Parity Lien Claimholders, agrees that any amounts
received by or distributed to any of them pursuant to or as a result of Liens
granted in contravention of this Section 2.3 shall be subject to Section 4.3.

            2.4 Similar Liens and Agreements. The parties hereto agree that it
is their intention that the First Lien Collateral and the Parity Lien Collateral
be identical. In furtherance of the foregoing and of Section 8.9, the parties
hereto agree, subject to the other provisions of this Agreement:

            (a) upon request by the First Lien Collateral Agent or the Parity
Lien Collateral Agent, to cooperate in good faith (and to direct their counsel
to cooperate in good faith) from time to time in order to determine the specific
items included in the First Lien Collateral and the Parity Lien Collateral and
the steps taken to perfect their respective Liens thereon and the identity of
the respective parties obligated under the First Lien Loan Documents and the
Parity Lien Documents; and

            (b) that, except to the extent that such documents and agreements
are replaced in connection with a Refinancing of any First Lien Debt or Second
Lien Debt as contemplated under Section 5.3, the documents and agreements
creating or evidencing the First Lien Collateral and the Parity Lien Collateral
and guarantees for the First Lien Obligations and the Parity Lien Obligations
subject to Section 5.3(d), shall be in all material respects the same forms of
documents other than with respect to the first lien and the second lien nature
of the Obligations thereunder.

            SECTION 3. ENFORCEMENT.

            3.1   Exercise of Remedies.

            (a)   Until the Discharge of First Lien Obligations has occurred,
whether or not any Insolvency or Liquidation Proceeding has been commenced by or
against the Company or any other Grantor, the Parity Lien Collateral Agent and
the Parity Lien Claimholders:

                  (1) will not exercise or seek to exercise any rights or
      remedies with respect to any Collateral (including the exercise of any
      right of setoff or any right under any lockbox agreement, account control
      agreement, landlord waiver or bailee's letter or similar agreement or
      arrangement to which the Parity Lien Collateral Agent or any Parity Lien
      Claimholder is a party) or institute any action or proceeding with respect
      to such rights or remedies (including any action of foreclosure);
      provided, however, that the Parity Lien Collateral Agent at the written
      direction of the Required Parity Lien Claimholders, may exercise any or
      all such rights or remedies after a period of at least 180 days has
      elapsed since the later of: (i) the date on which the Parity Lien
      Collateral Agent, at the written direction of the Required Parity Lien
      Claimholders, declared the existence of any Event of Default under any
      Parity Lien Documents and demanded the repayment of all the principal
      amount of any Parity Lien Obligations; and (ii) the date on which the
      First Lien Collateral Agent received notice from the Parity Lien
      Collateral Agent of such declarations of an Event of Default and demand
      for repayment (the "STANDSTILL PERIOD"); provided, further, however, that
      notwithstanding anything herein to the contrary, in no event shall the
      Parity Lien Collateral Agent or any Parity Lien Claimholder exercise any
      rights or remedies with respect to the Collateral if, notwithstanding the
      expiration of the Standstill Period, the First Lien Collateral Agent or
      First Lien Claimholders shall have commenced and be diligently pursuing
      the exercise of their rights or remedies with respect to all or any
      material portion of the Collateral (prompt notice of such exercise to be
      given to the Parity Lien Collateral Agent);

                  (2) will not contest, protest or object to any foreclosure
      proceeding or action brought by the First Lien Collateral Agent or any
      First Lien Claimholder or any other exercise by the First Lien Collateral
      Agent or any First Lien Claimholder of any rights and remedies relating to
      the Collateral under the First Lien Loan Documents or otherwise; and

                  (3) subject to their rights under clause (a)(1) above and
      except as may be permitted in Section 3.1(c), will not object to the
      forbearance by the First Lien Collateral Agent or the First Lien
      Claimholders from bringing or pursuing any foreclosure proceeding or
      action or any other exercise of any rights or remedies relating to the
      Collateral;

      provided, that, in the case of (1), (2) and (3) above, the Liens granted
      to secure the Parity Lien Obligations of the Parity Lien Claimholders
      shall attach to any proceeds

                                       16
<PAGE>

      resulting from actions taken by the First Lien Collateral Agent or any
      First Lien Claimholder in accordance with this Agreement after application
      of such proceeds to the extent necessary to meet the requirements of a
      Discharge of First Lien Obligations.

            (b)   Until the Discharge of First Lien Obligations has occurred,
whether or not any Insolvency or Liquidation Proceeding has been commenced by or
against the Company or any other Grantor, subject to Section 3.1(a)(1), the
First Lien Collateral Agent and the First Lien Claimholders shall have the right
to enforce rights, exercise remedies (including set-off and the right to credit
bid their debt) and make determinations regarding the release, disposition, or
restrictions with respect to the Collateral without any consultation with or the
consent of the Parity Lien Collateral Agent or any Parity Lien Claimholder;
provided, that the Lien securing the Parity Lien Obligations shall remain on the
proceeds of such Collateral released or disposed of subject to the relative
priorities described in Section 2. In exercising rights and remedies with
respect to the Collateral, the First Lien Collateral Agent and the First Lien
Claimholders may, subject to the rights of the Company and the other Grantors
thereunder, enforce the provisions of the First Lien Loan Documents and exercise
remedies thereunder, all in such order and in such manner as they may determine
in the exercise of their sole discretion. Such exercise and enforcement shall
include the rights of an agent appointed by them to sell or otherwise dispose of
Collateral upon foreclosure, to incur expenses in connection with such sale or
disposition, and to exercise all the rights and remedies of a secured creditor
under the UCC and of a secured creditor under Bankruptcy Laws of any applicable
jurisdiction.

            (c)   Notwithstanding the foregoing, the Parity Lien Collateral
Agent and any Parity Lien Claimholder may:

                  (1) file a claim or statement of interest with respect to the
      Parity Lien Obligations; provided that an Insolvency or Liquidation
      Proceeding has been commenced by or against the Company or any other
      Grantor;

                  (2) take any action (not adverse to the priority status of the
      Liens on the Collateral securing the First Lien Obligations, or the rights
      of any First Lien Collateral Agent or the First Lien Claimholders to
      exercise remedies in respect thereof) in order to create, perfect,
      preserve or protect its Lien on the Collateral;

                  (3) file any necessary responsive or defensive pleadings in
      opposition to any motion, claim, adversary proceeding or other pleading
      made by any person objecting to or otherwise seeking the disallowance of
      the claims of the Parity Lien Claimholders, including any claims secured
      by the Collateral, if any, in each case in accordance with the terms of
      this Agreement;

                  (4) file any pleadings, objections, motions or agreements
      which assert rights or interests available to unsecured creditors of the
      Grantors arising under either any Insolvency or Liquidation Proceeding or
      applicable non-bankruptcy law, in each case not inconsistent with the
      terms of this Agreement;

                                       17
<PAGE>

                  (5) vote on any plan of reorganization, file any proof of
      claim, make other filings and make any arguments and motions that are, in
      each case, in accordance with the terms of this Agreement, with respect to
      the Parity Lien Obligations and the Collateral; and

                  (6) exercise any of its rights or remedies with respect to the
      Collateral after the termination of the Standstill Period to the extent
      permitted by Section 3.1(a)(1).

            The Parity Lien Collateral Agent, on behalf of itself and the Parity
Lien Claimholders, agrees that it will not take or receive any Collateral or any
proceeds of Collateral in connection with the exercise of any right or remedy
(including set-off) with respect to any Collateral in its capacity as a creditor
in violation of this Agreement. Without limiting the generality of the
foregoing, unless and until the Discharge of First Lien Obligations has
occurred, except as expressly provided in Sections 3.1(a), 6.3(b) and this
Section 3.1(c), the sole right of the Parity Lien Collateral Agent and the
Parity Lien Claimholders with respect to the Collateral is to hold a Lien on the
Collateral pursuant to the Parity Lien Collateral Documents for the period and
to the extent granted therein and to receive a share of the proceeds thereof, if
any, after the Discharge of First Lien Obligations has occurred.

            (d)   Subject to Sections 3.1(a) and (c) and Section 6.3(b):

                  (1) the Parity Lien Collateral Agent, for itself and on behalf
      of the Parity Lien Claimholders, agrees that the Parity Lien Collateral
      Agent and the Parity Lien Claimholders will not take any action that would
      hinder any exercise of remedies under the First Lien Loan Documents or is
      otherwise prohibited hereunder, including any sale, lease, exchange,
      transfer or other disposition of the Collateral, whether by foreclosure or
      otherwise;

                  (2) the Parity Lien Collateral Agent, for itself and on behalf
      of the Parity Lien Claimholders, hereby waives any and all rights it or
      the Parity Lien Claimholders may have as a junior lien creditor or
      otherwise to object to the manner in which the First Lien Collateral Agent
      or the First Lien Claimholders seek to enforce or collect the First Lien
      Obligations or the Liens securing the First Lien Obligations granted in
      any of the First Lien Collateral undertaken in accordance with this
      Agreement, regardless of whether any action or failure to act by or on
      behalf of the First Lien Collateral Agent or First Lien Claimholders is
      adverse to the interest of the Parity Lien Claimholders; and

                  (3) the Parity Lien Collateral Agent hereby acknowledges and
      agrees that no covenant, agreement or restriction contained in the Parity
      Lien Collateral Documents or any other Parity Lien Document (other than
      this Agreement) shall be deemed to restrict in any way the rights and
      remedies of the First Lien Collateral Agent or the First Lien Claimholders
      with respect to the Collateral as set forth in this Agreement and the
      First Lien Credit Documents.

                                       18
<PAGE>

            (e)   Except as otherwise specifically set forth in Sections 3.1(a)
and (d), the Parity Lien Collateral Agent and the Parity Lien Claimholders may
exercise rights and remedies as unsecured creditors against the Company or any
other Grantor that has guaranteed or granted Liens to secure the Parity Lien
Obligations in accordance with the terms of the Parity Lien Documents and
applicable law; provided that in the event that any Parity Lien Claimholder
becomes a judgment Lien creditor in respect of Collateral as a result of its
enforcement of its rights as an unsecured creditor with respect to the Parity
Lien Obligations, such judgment Lien shall be subject to the terms of this
Agreement for all purposes (including in relation to the First Lien Obligations)
as the other Liens securing the Parity Lien Obligations are subject to this
Agreement.

            (f)   Nothing in this Agreement shall prohibit the receipt by the
Parity Lien Collateral Agent or any Parity Lien Claimholders of the required
payments of interest, principal and other amounts owed in respect of the Parity
Lien Obligations so long as such receipt is not the direct or indirect result of
the exercise by the Parity Lien Collateral Agent or any Parity Lien Claimholders
of rights or remedies as a secured creditor (including set-off) or enforcement
in contravention of this Agreement of any Lien held by any of them. Nothing in
this Agreement impairs or otherwise adversely affects any rights or remedies the
First Lien Collateral Agent or the First Lien Claimholders may have with respect
to the First Lien Collateral.

            (g)   Notwithstanding the foregoing, subject to the rights of any
holders of First Lien Obligations, at any time after the Discharge of the First
Lien Obligations, the Parity Lien Claimholders may, at the written direction of
the Required Parity Lien Claimholders, direct the Parity Lien Collateral Agent
to enforce rights, exercise remedies and take actions to which it may be
entitled under the Parity Lien Documents:

                  (1) to foreclose upon and otherwise enforce Liens on the
      Collateral securing such Parity Lien Obligations at any time after the
      Standstill Period;

                  (2) as necessary to redeem any Collateral in a creditor's
      redemption permitted by law or to deliver any notice or demand necessary
      to enforce any right to claim, take or receive proceeds of such Collateral
      remaining after the Discharge of First Priority Lien Obligations in the
      event of foreclosure or other enforcement of any prior Lien;

                  (3) as necessary to perfect or establish the priority of Liens
      on any Collateral securing such Parity Lien Obligations;

                  (4) as necessary to create, prove, preserve or protect Liens
      on any Collateral securing such Parity Lien Obligations.

            (h)   In connection with any matters requiring a vote of the
Required Parity Lien Claimholders, the votes of the Second Lien Lenders and the
votes of holders of other Parity Lien Debt entitled to vote thereon shall be
cast in the manner provided by, and in accordance with the terms of, the
corresponding Parity Lien Documents.

                                       19

            For the purposes of the foregoing, any notes registered in the name
of, or Beneficially Owned by, the Company or any Affiliate of the Company will
be deemed not to be outstanding.

Document to the contrary, Company shall not make any voluntary or mandatory

that in the event that (i) there shall be no First Lien Term Loans outstanding

Funded Letter of Credit Commitments does not exceed $340,000,000, then Company
may make voluntary prepayments of outstanding loans under the Second Lien Credit

contemplated under pursuant to Sections 2.14(c) and (e), respectively, of the
First Lien Credit Agreement and the Second Lien Credit Agreement, shall first be
applied to amounts outstanding under the Second Lien Credit Agreement.

            4.2 Application of Proceeds Upon Exercise of Remedies.

            (a) Prior to the Discharge of First Lien Obligations, if pursuant to
the exercise by the First Lien Collateral Agent of any rights and remedies set
forth in any First Lien Collateral Document, any Collateral is sold or otherwise
realized upon by the First Lien Collateral Agent, the First Lien Collateral
Agent shall, after distributing amounts required to be paid to holders of
"Allowed Class 6 Claims" (as such term is defined in the Plan of Reorganization)
and other entitled claimants with respect to the "CPIH Participation Interest"
(as such term is defined in the Plan of Reorganization) in an aggregate amount
not to exceed $4,000,000, promptly distribute the proceeds received in respect
of such Collateral in the following order of application:

            FIRST, to the payment of all amounts payable under the First Lien
Loan Documents on account of the First Lien Collateral Agent's fees and any
reasonable legal fees, costs and expenses or other liabilities of any kind
incurred by the First Lien Collateral Agent or any co-trustee or agent of the
First Lien Collateral Agent in connection with any First Lien Collateral
Document;

            SECOND, to the extent of any excess of such proceeds, to the First
Lien Administrative Agent for application to the payment of all outstanding
First Lien Obligations that are then due and payable ratably in an amount
sufficient to pay in full in cash all outstanding First Lien Obligations that
are then due and payable (including, to the extent legally permitted, all
interest accrued thereon after the commencement of any insolvency or liquidation
proceeding at the rate, including any applicable post-default rate,

                                       20
<PAGE>

specified in the First Lien Loan Documents, even if such interest is not
enforceable, allowable or allowed as a claim in such proceeding, and including
the discharge or cash collateralization (at the lower of (1) 105% of the
aggregate undrawn amount and (2) the percentage of the aggregate undrawn amount
required for release of Liens under the terms of the applicable First Lien Loan
Document) of all outstanding letters of credit constituting First Lien
Obligations);

            THIRD, to the extent of any excess of such proceeds, to the Parity
Lien Collateral Agent for the payment of all amounts payable under the Parity
Lien Documents on account of the Parity Lien Collateral Agent's fees and any
reasonable legal fees, costs and expenses or other liabilities of any kind
incurred by the Parity Lien Collateral Agent or any co-trustee or agent of the
Parity Lien Collateral Agent in connection with any such Parity Lien Document;

            FOURTH, to the extent of any excess of such proceeds, to the Second
Lien Administrative Agent and any comparable Parity Lien Representative for
application to the payment of all outstanding Parity Lien Obligations that are
then due and payable Equally and Ratably pursuant to the terms of the Parity
Lien Documents in an amount sufficient to pay in full in cash all outstanding
Parity Lien Obligations that are then due and payable (including, to the extent
legally permitted, all interest accrued thereon after the commencement of any
insolvency or liquidation proceeding at the rate, including any applicable
post-default rate, specified in the Parity Lien Documents, even if such interest
is not enforceable, allowable or allowed as a claim in such proceeding);

            FIFTH, any surplus remaining after the payment in full in cash of
the amounts described in the preceding clauses will be paid to the Company or
the applicable Grantor, as the case may be, its successors or assigns, or as a
court of competent jurisdiction may direct.

            (b) Following the Discharge of First Lien Obligations, if any
Collateral is sold or otherwise realized upon by the Parity Lien Collateral
Agent in connection with any foreclosure, collection or other enforcement of
Liens granted to the Parity Lien Collateral Agent in the Parity Lien Collateral
Documents, the proceeds received by the Parity Lien Collateral Agent from such
foreclosure, collection or other enforcement will be distributed by the Parity
Lien Collateral Agent in accordance with clauses THIRD, FOURTH and FIFTH, as
applicable, of Section 4.2(a).

            4.3 Payments Over in Violation of Agreement. So long as the
Discharge of First Lien Obligations has not occurred, whether or not any
Insolvency or Liquidation Proceeding has been commenced by or against the
Company or any other Grantor, any Collateral or proceeds thereof (including
assets or proceeds subject to Liens referred to in the final sentence of Section
2.3) received by the Parity Lien Collateral Agent or any Parity Lien
Claimholders in connection with the exercise of any right or remedy (including
set-off) relating to the Collateral in contravention of this Agreement shall be
segregated and held in trust and forthwith paid over to the First Lien
Collateral Agent for the benefit of the First Lien Claimholders in the same form
as received, with any necessary endorsements or as a court of competent
jurisdiction may otherwise direct. The First Lien Collateral

                                       21
<PAGE>

Agent is hereby authorized to make any such endorsements as agent for the Parity
Lien Collateral Agent or any such Parity Lien Claimholders. This authorization
is coupled with an interest and is irrevocable until the Discharge of First Lien
Obligations.

            SECTION 5. OTHER AGREEMENTS.

            5.1 Releases.

            (a) If in connection with the exercise of the First Lien Collateral
Agent's remedies in respect of the Collateral provided for in Section 3.1, the
First Lien Collateral Agent, for itself or on behalf of any of the First Lien
Claimholders, releases any of its Liens on any part of the Collateral or
releases any Grantor from its obligations under its guaranty of the First Lien
Obligations in connection with the sale of the stock, or substantially all the
assets, of such Grantor, then the Liens, if any, of the Parity Lien Collateral
Agent, for itself or for the benefit of the Parity Lien Claimholders, on such
Collateral, and the obligations of such Grantor under its guaranty of the Parity
Lien Obligations, shall be automatically, unconditionally and simultaneously
released. The Parity Lien Collateral Agent, for itself or on behalf of any such
Parity Lien Claimholders, promptly shall execute and deliver to the First Lien
Collateral Agent or such Grantor such releases and other documents as the First
Lien Collateral Agent or such Grantor may request, and authorizes the filing of
any termination statements, to effectively confirm such release.

            (b) If in connection with any sale, lease, exchange, transfer or
other disposition of any Collateral (collectively, a "DISPOSITION") permitted
under the terms of both the First Lien Loan Documents and the Parity Lien
Documents (other than in connection with the exercise of the First Lien
Collateral Agent's remedies in respect of the Collateral provided for in Section
3.1), the First Lien Collateral Agent, for itself or on behalf of any of the
First Lien Claimholders, releases any of its Liens on any part of the
Collateral, or releases any Grantor from its obligations under its guaranty of
the First Lien Obligations in connection with the sale of the stock, or
substantially all the assets, of such Grantor, in each case other than (A) in
connection with the Discharge of First Lien Obligations and (B) after the
occurrence and during the continuance of any Event of Default under any Parity
Lien Document, then the Liens, if any, of the Parity Lien Collateral Agent, for
itself or for the benefit of the Parity Lien Claimholders, on such Collateral,
and the obligations of such Grantor under its guaranty of the Parity Lien
Obligations, shall be automatically, unconditionally and simultaneously
released. The Parity Lien Collateral Agent, for itself or on behalf of any such
Parity Lien Claimholders, promptly shall execute and deliver to the First Lien
Collateral Agent or such Grantor such releases and other documents as the First
Lien Collateral Agent or such Grantor may request, and authorizes the filing of
any termination statements, to effectively confirm such release.

            (c) Until the Discharge of First Lien Obligations occurs, the Parity
Lien Collateral Agent, for itself and on behalf of the Parity Lien Claimholders,
hereby irrevocably constitutes and appoints the First Lien Collateral Agent and
any officer or agent of the First Lien Collateral Agent, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of

                                       22
<PAGE>

the Parity Lien Collateral Agent or such holder or in the First Lien Collateral
Agent's own name, from time to time in the First Lien Collateral Agent's
discretion, for the purpose of carrying out the terms of this Section 5.1, to
take any and all appropriate action and to execute any and all documents and
instruments which may be necessary to accomplish the purposes of this Section
5.1, including any endorsements or other instruments of transfer or release.

            (d) Until the Discharge of First Lien Obligations occurs, to the
extent that the First Lien Collateral Agent or the First Lien Claimholders (i)
have released any Lien on Collateral or any Grantor from its obligation under
its guaranty and any such Liens or guaranty are later reinstated or (ii) obtain
any new liens or additional guarantees from any Grantor, then the Parity Lien
Collateral Agent, for itself and for the Parity Lien Claimholders, shall be
granted a Lien on any such Collateral, subject to the lien subordination
provisions of this Agreement, and an additional guaranty, as the case may be.

            (e) In the event that the principal amount of funded First Lien
Obligations plus the aggregate face amount of letters of credit, if any, issued
under the First Lien Credit Agreement and not reimbursed plus the aggregate
principal amount of unfunded commitments under the First Lien Credit Agreement
(collectively, the "FIRST LIEN OBLIGATIONS AMOUNT"), at any date of
determination no longer constitute at least 15% of the sum of (i) the First Lien
Obligations Amount and (ii) the principal amount of funded Parity Lien
Obligations (collectively, the "PARITY LIEN OBLIGATIONS AMOUNT"), then, with
respect to Collateral, any action provided for in Section 5.1(a) and (b) above
(except for releases given in connection with a Disposition or guarantor
releases permitted under the First Lien Loan Documents and the Parity Lien
Documents) shall require the consent of First Lien Claimholders and Parity Lien
Claimholders representing in the aggregate more than 50% of the sum of (i) the
First Lien Obligations Amount and (ii) the Parity Lien Obligations Amount.

            (f) After the Discharge of First Lien Obligations occurs, any sale,
lease, exchange, transfer or other dispositions of Collateral or any other
release of Liens on any part of the Collateral or any releases of any Grantor
from its obligations under its guaranty of the Parity Lien Obligations in
connection with the sale of the stock, or substantially all the assets, of such
Grantor in each case not otherwise expressly permitted under the Parity Lien
Documents shall only be permitted with the written consent of the Required
Parity Lien Claimholders.

            5.2 Insurance. Unless and until the Discharge of First Lien
Obligations has occurred, and subject to Section 4.1(a) hereof and the terms of,
and the rights of the Grantors under, the First Lien Loan Documents, all
proceeds of any policy covering the Collateral and any award granted in any
condemnation or similar proceeding (or any payments with respect to a deed in
lieu of condemnation) if in respect of the Collateral and to the extent required
by the First Lien Loan Documents to be paid to the First Lien Collateral Agent
for the benefit of the First Lien Claimholders pursuant to the terms of the
First Lien Credit Documents (including, without limitation, for purposes of cash
collateralization of letters of credit) shall be so paid and thereafter, subject
to Section 4.1(a) hereof and the terms of, and the rights of the Grantors under,
the Parity Lien

                                       23
<PAGE>

Collateral Documents, to the Parity Lien Collateral Agent for the benefit of the
Parity Lien Claimholders to the extent required under the Parity Lien Collateral
Documents and then, to the extent no Parity Lien Obligations are outstanding, to
the owner of the subject property, such other Person as may be entitled thereto
or as a court of competent jurisdiction may otherwise direct. Until the
Discharge of First Lien Obligations has occurred, if the Parity Lien Collateral
Agent or any Parity Lien Claimholders shall, at any time, receive any proceeds
of any such insurance policy or any such award or payment in contravention of
this Agreement, it shall segregate and hold in trust and forthwith pay such
proceeds over to the First Lien Collateral Agent in accordance with the terms of
Section 4.3.

            5.3   Amendments to First Lien Loan Documents and Parity Lien
Documents.

            (a)   The First Lien Loan Documents may be amended, restated,
supplemented or otherwise modified in accordance with their terms and the First
Lien Credit Agreement may be Refinanced, in whole or in part, in each case,
without notice to, or the consent of the Parity Lien Collateral Agent or the
Parity Lien Claimholders, all without affecting the lien subordination or other
provisions of this Agreement; provided, however, that the holders of such
Refinancing debt bind themselves in a writing addressed to the Parity Lien
Collateral Agent and the Parity Lien Claimholders to the terms of this Agreement
and any such amendment, supplement, modification or Refinancing shall not,
without the consent of the Parity Lien Collateral Agent:

                  (1)   increase the sum of (without duplication) (A) the then
      outstanding aggregate principal amount of the First Lien Term Loans (or
      other similar facilities) under the First Lien Credit Agreement and (B)
      the aggregate amount of First Lien Revolving Commitment and the First Lien
      Funded Letter of Credit Commitment (or other similar facilities) under the
      First Lien Credit Agreement in excess of the Cap Amount;

                  (2)   increase the "Applicable Margin" or similar component of
      the interest rate or yield provisions applicable to the First Lien
      Obligations (and/or issue refinancing indebtedness at a discount) so long
      as the combined effect of such increase and/or discount does not increase
      the financing costs by more than 2.00% per annum (excluding increases (A)
      resulting from application of the pricing grid set forth in the First Lien
      Credit Agreement as in effect on the date hereof or (B) resulting from the
      accrual of interest at the default rate);

                  (3)   extend the scheduled maturity of the First Lien Credit
      Agreement or any Refinancing thereof beyond the scheduled maturity of any
      Parity Lien Document or any Refinancing thereof; or

                  (4)   contravene the provisions of this Agreement.

            Upon any Refinancing of the First Lien Debt in accordance with the
foregoing provisions (i) the Indebtedness incurred in connection with such
Refinancing

                                       24
<PAGE>

shall constitute First Lien Debt, (ii) the holders of such First
Lien Debt shall constitute First Lien Lenders, (iii) the principal documents
governing such Indebtedness or pursuant to which such Indebtedness is issued
shall constitute the First Lien Credit Agreement and the documents and
instruments executed in connection with such new Indebtedness shall constitute
First Lien Loan Documents and (iv) the Person to whom Liens on the Collateral
are granted to secured the Indebtedness so Refinanced shall constitute the First
Lien Collateral Agent.

            (b)   Without the prior written consent of the First Lien Collateral
Agent, no Parity Lien Document may be Refinanced, amended, restated,
supplemented or otherwise modified or entered into to the extent such
Refinancing, amendment, supplement or modification, or the terms of any new
Parity Lien Document, would:

                  (1) increase the principal amount of the Parity Lien Debt in
      excess of the amount permitted under the First Lien Credit Agreement;

                  (2) increase the "Applicable Margin" or similar component of
      the interest rate or yield provisions applicable to the Parity Lien
      Obligations (and/or issue refinancing indebtedness at a discount) so long
      as the combined effect of such increase and/or discount does not increase
      the financing costs by more than 2.00% per annum (excluding increases
      resulting from the accrual of interest at the default rate);

                  (3) change any default or Event of Default thereunder in a
      manner materially adverse to the loan parties thereunder (other than to
      eliminate any such Event of Default or increase any grace period related
      thereto or otherwise make such Event of Default or condition less
      restrictive or burdensome on the Company);

                  (4) change (to earlier dates) any dates upon which payments of
      principal or interest are due thereon;

                  (5) change the prepayment provisions thereof;

                  (6) increase materially the obligations of the obligor
      thereunder or to confer any additional material rights on the lenders or
      holders under the Parity Lien Documents (or a representative on their
      behalf) which would be materially adverse to any Credit Party (as defined
      in the First Lien Credit Agreement) or First Lien Lenders; or

                  (7) contravene the provisions of this Agreement.

            The Parity Lien Documents may be Refinanced as permitted under the
First Lien Credit Agreement and to the extent the terms and conditions of such
Refinancing debt meet the requirements of this Section 5.3(b), the average life
to maturity thereof is greater than or equal to that of the Second Lien Credit
Agreement and the holders of such Refinancing debt bind themselves in a writing
addressed to the First Lien Collateral Agent and the First Lien Claimholders to
the terms of this Agreement.

                                       25
<PAGE>

            (c)   Each Parity Lien Collateral Document shall include the
following language (or language to similar effect approved by the First Lien
Collateral Agent):

            "Notwithstanding anything herein to the contrary, the lien and
            security interest granted to the Parity Lien Collateral Agent
            pursuant to this Agreement and the exercise of any right or remedy
            by the Parity Lien Collateral Agent hereunder are subject to the
            provisions of the Intercreditor Agreement, dated as of June [__] (as
            amended, restated, supplemented or otherwise modified from time to
            time, the "INTERCREDITOR AGREEMENT"), among Covanta Energy
            Corporation, _______________, as First Lien Collateral Agent and
            ______________, as Parity Lien Collateral Agent and certain other
            persons party or that may become party thereto from time to time. In
            the event of any conflict between the terms of the Intercreditor
            Agreement and this Agreement, the terms of the Intercreditor
            Agreement shall govern and control."

In addition, each Parity Lien Mortgage covering any Collateral shall contain
such other language as the First Lien Collateral Agent may reasonably request to
reflect the subordination of such Parity Lien Mortgage to the First Lien
Collateral Document covering such Collateral.

            (d)   In the event any First Lien Collateral Agent or the First Lien
Claimholders and the relevant Grantor enter into any amendment, waiver or
consent in respect of any of the First Lien Collateral Documents for the purpose
of adding to, or deleting from, or waiving or consenting to any departures from
any provisions of, any First Lien Collateral Document or changing in any manner
the rights of the First Lien Collateral Agent, such First Lien Claimholders, the
Company or any other Grantor thereunder, then upon the execution by each
appropriate Grantor of a grant of security interest in an additional or
supplemental collateral, such amendment, waiver or consent shall apply
automatically to any comparable provision of the Comparable Parity Lien
Collateral Document without the consent of the Parity Lien Collateral Agent or
the Parity Lien Claimholders and without any action by the Parity Lien
Collateral Agent, the Company or any other Grantor, provided, that:

                  (1)   no such amendment, waiver or consent shall have the
      effect of:

                        (A) removing or releasing assets subject to the Lien of
            the Parity Lien Collateral Documents, except to the extent that a
            release of such Lien is permitted or required by Section 5.1 of this
            Agreement and provided that there is a corresponding release of the
            Liens securing the First Lien Obligations;

                        (B) imposing duties on the Parity Lien Collateral Agent
            without its consent;

                                       26
<PAGE>

                        (C) permitting other Liens on the Collateral not
            permitted under the terms of the Parity Lien Documents or Section 6;
            or

                        (D) being prejudicial to the interests of the Parity
            Lien Claimholders to a greater extent than the First Lien
            Claimholders; and

                  (2) notice of such amendment, waiver or consent shall have
      been given to the Parity Lien Collateral Agent within ten (10) Business
      Days after the effective date of such amendment, waiver or consent.

            5.4 Bailee for Perfection.

            (a) The First Lien Collateral Agent agrees to hold that part of the
Collateral that is in its possession or control (or in the possession or control
of its agents or bailees) to the extent that possession or control thereof is
taken to perfect a Lien thereon under the UCC (such Collateral being the
"PLEDGED COLLATERAL") as collateral agent for the First Lien Claimholders and as
bailee for the Parity Lien Collateral Agent (such bailment being intended, among
other things, to satisfy the requirements of Sections 8-301(a)(2) and 9-313(c)
of the UCC) and any assignee solely for the purpose of perfecting the security
interest granted under the First Lien Loan Documents and the Parity Lien
Documents, respectively, subject to the terms and conditions of this Section
5.4.

            (b) The First Lien Collateral Agent shall have no obligation
whatsoever to the First Lien Claimholders, the Parity Lien Collateral Agent or
any Parity Lien Claimholder to ensure that the Pledged Collateral is genuine or
owned by any of the Grantors or to preserve rights or benefits of any Person
except as expressly set forth in this Section 5.4. The duties or
responsibilities of the First Lien Collateral Agent under this Section 5.4 shall
be limited solely to holding the Pledged Collateral as bailee in accordance with
this Section 5.4 and delivering the Pledged Collateral upon a Discharge of First
Lien Obligations as provided in paragraph (d) below.

            (c) The First Lien Collateral Agent acting pursuant to this Section
5.4 shall not have by reason of the First Lien Collateral Documents, the Parity
Lien Collateral Documents, this Agreement or any other document a fiduciary
relationship in respect of the First Lien Claimholders, the Parity Lien
Collateral Agent or any Parity Lien Claimholder.

            (d) Upon the Discharge of First Lien Obligations under the First
Lien Loan Documents to which the First Lien Collateral Agent is a party, the
First Lien Collateral Agent shall deliver the remaining Pledged Collateral (if
any) together with any necessary endorsements, first, to the Parity Lien
Collateral Agent to the extent Parity Lien Obligations remain outstanding, and
second, to the Company to the extent no First Lien Obligations or Parity Lien
Obligations remain outstanding (in each case, so as to allow such Person to
obtain possession or control of such Pledged Collateral). The First Lien
Collateral Agent further agrees to take all other action reasonably requested by
the Parity Lien Collateral Agent in connection with the Parity Lien Collateral
Agent obtaining a first-priority security interest (subject to Permitted Liens)
in the Collateral or as a court of competent jurisdiction may otherwise direct.

                                       27

<PAGE>

            (e) Subject to the terms of this Agreement, so long as the Discharge
of First Lien Obligations has not occurred, the First Lien Collateral Agent
shall be entitled to deal with the Pledged Collateral or Collateral within its
"control" in accordance with the terms of this Agreement and other First Lien
Credit Documents as if the Liens of the Parity Lien Collateral Agent and Parity
Lien Claimholders did not exist.

            5.5 When Discharge of First Lien Obligations Deemed to Not Have
Occurred. If concurrently with the Discharge of First Lien Obligations, the
Company thereafter enters into any Refinancing of any First Lien Loan Document
evidencing a First Lien Obligation which Refinancing is permitted by the Parity
Lien Documents, then such Discharge of First Lien Obligations shall
automatically be deemed not to have occurred for all purposes of this Agreement
(other than with respect to any actions taken by the Parity Lien Collateral
Agent as a result of the occurrence of such first Discharge of First Lien
Obligations), and, from and after the date on which the New First Lien Debt
Notice (as defined below) is delivered to the Parity Lien Collateral Agent in
accordance with the next sentence, the obligations under such Refinancing of the
First Lien Loan Document shall automatically be treated as First Lien
Obligations for all purposes of this Agreement, including for purposes of the
Lien priorities and rights in respect of Collateral set forth herein, and the
First Lien Collateral Agent under such First Lien Loan Documents shall be the
First Lien Collateral Agent for all purposes of this Agreement. Upon receipt of
a notice (the "NEW FIRST LIEN DEBT NOTICE") stating that the Company has entered
into a new First Lien Loan Document (which notice shall include the identity of
the new first lien collateral agent, such agent, the "NEW AGENT"), the Parity
Lien Collateral Agent shall promptly (a) enter into such documents and
agreements (including amendments or supplements to this Agreement) as the
Company or such New Agent shall reasonably request in order to provide to the
New Agent the rights contemplated hereby, in each case consistent in all
material respects with the terms of this Agreement and (b) deliver to the New
Agent any Pledged Collateral held by it together with any necessary endorsements
(or otherwise allow the New Agent to obtain control of such Pledged Collateral).
The New Agent shall agree in a writing addressed to the Parity Lien Collateral
Agent and the Parity Lien Claimholders to be bound by the terms of this
Agreement. If the new First Lien Obligations under the new First Lien Loan
Documents are secured by assets of the Grantors constituting Collateral that do
not also secure the Parity Lien Obligations, then the Grantors shall take all
actions reasonably requested to cause the Parity Lien Obligations to be secured
at such time by a second priority Lien on such assets to the same extent
provided in the Parity Lien Collateral Documents and this Agreement.

            5.6 Purchase Right. Without prejudice to the enforcement of the
First Lien Claimholders remedies, the First Lien Claimholders agree at any time
following an acceleration of the First Lien Obligations in accordance with the
terms of the First Lien Credit Agreement, the First Lien Claimholders will offer
the Parity Lien Claimholders the option to purchase the entire aggregate amount
of outstanding First Lien Obligations (including unfunded commitments under the
First Lien Credit Agreement) at par plus accrued interest (without regard to any
prepayment penalty or premium), without warranty or representation or recourse,
on a pro rata basis across First Lien Claimholders. The Parity Lien Claimholders
shall irrevocably accept or reject such offer within ten (10) Business Days of
the receipt thereof and the parties shall endeavor to close promptly

                                       28

<PAGE>

thereafter. If the Parity Lien Claimholders accept such offer, it shall be
exercised pursuant to documentation mutually acceptable to each of the First
Lien Collateral Agent and the Parity Lien Collateral Agent. If the Parity Lien
Claimholders reject such offer (or do not so irrevocably accept such offer
within the required timeframe), the First Lien Claimholders shall have no
further obligations pursuant to this Section 5.6 and may take any further
actions in their sole discretion in accordance with the First Lien Loan
Documents and this Agreement.

            5.7 Additional Parity Lien Debt.

            (a) The Parity Lien Collateral Agent will accept, enter into, hold,
maintain, administer and enforce all Parity Lien Collateral Documents, including
all Collateral subject thereto, and all Liens created thereunder, perform its
obligations under the Parity Lien Obligations and protect, exercise and enforce
the interests, rights, powers and remedies granted or available to it under,
pursuant to or in connection with the Parity Lien Collateral Documents, with
respect to each holder of Obligations of a Series of Parity Lien Debt that is
issued or incurred after the date hereof that:

                  (1) holds Obligations that are identified as Parity Lien Debt
      in accordance with the procedures set forth in Section 5.7(b);

                  (2) signs, through its designated Parity Lien Representative
      identified pursuant to Section 5.7 (b), an Intercreditor Joinder; and

                  (3) delivers a Lien Sharing and Priority Confirmation.

            (b) The Company or other applicable Guarantor Subsidiary will be
permitted to designate as an additional holder of Parity Lien Obligations
hereunder each Person who is, or who becomes, the registered holder of Parity
Lien Debt or the registered holder of Priority Lien Debt incurred by the Company
or such other Guarantor Subsidiary after the date of this Agreement in
accordance with the terms of all applicable Secured Debt Documents. The Company
or other Guarantor Subsidiary may effect such designation by delivering to the
Parity Lien Collateral Agent, with copies to each previously identified Parity
Lien Representative, each of the following:

                  (1) an Officers' Certificate stating that:

                        (A) the Company or other applicable Guarantor Subsidiary
            intends to incur additional Parity Lien Debt which will be Parity
            Lien Debt permitted by each applicable Secured Debt Document to be
            secured with a Parity Lien Equally and Ratably with all previously
            existing and future Parity Lien Debt;

                  (2) evidence that the Company or such other Guarantor
      Subsidiary has duly authorized, executed (if applicable) and recorded (or
      caused to be recorded) in each appropriate governmental office all
      relevant filings and recordations to ensure that the additional Parity
      Lien Debt is secured by the Collateral in accordance with the Parity Lien
      Collateral Documents; and

                                       29

<PAGE>

                  (3) a written notice specifying the name and address of the
      Parity Lien Representative for such series of additional Parity Lien Debt
      for purposes of Section 8.8.

Notwithstanding the foregoing, nothing in this Agreement will be construed to
allow the Company or any other Guarantor Subsidiary to incur additional
Indebtedness unless otherwise permitted by the terms of all applicable Secured
Debt Documents.

            SECTION 6. INSOLVENCY OR LIQUIDATION PROCEEDINGS.

            6.1 Finance and Sale Issues. Until the Discharge of First Lien
Obligations has occurred, if the Company or any other Grantor shall be subject
to any Insolvency or Liquidation Proceeding and the First Lien Collateral Agent
shall desire to permit the use of "Cash Collateral" (as such term is defined in
Section 363(a) of the Bankruptcy Code), on which the First Lien Collateral Agent
or any other creditor has a Lien or to permit the Company or any other Grantor
to obtain financing, whether from the First Lien Claimholders or any other
Person under Section 364 of the Bankruptcy Code or any similar Bankruptcy Law
("DIP FINANCING") then the Parity Lien Collateral Agent, on behalf of itself and
the Parity Lien Claimholders, agrees that neither it nor any other Parity Lien
Claimholder will raise any objection to such Cash Collateral use or DIP
Financing so long as such Cash Collateral use or DIP Financing is (i) on
commercially reasonable terms, (ii) the Parity Lien Collateral Agent and the
Parity Lien Claimholders retain the right to object to any ancillary agreements
or arrangements regarding the Cash Collateral use or the DIP Financing that are
materially prejudicial to their interests and (iii) the DIP Financing (a) does
not compel the Company to seek confirmation of a specific plan of reorganization
for which all or substantially all of the material terms are set forth in the
DIP Financing documentation or a related document or (b) the DIP Financing
documentation or Cash Collateral order does not expressly require the
liquidation of the Collateral prior to a default under the DIP Financing
documentation or Cash Collateral order. To the extent the Liens securing the
First Lien Obligations are subordinated to or pari passu with such DIP Financing
which meets the requirements of clauses (i) through (iii) above, the Parity Lien
Collateral Agent will subordinate (and will be deemed hereunder to have
subordinated) its Liens in the Collateral (x) to the Liens securing such DIP
Financing (and all Obligations relating thereto), (y) to any adequate
protections given to the First Lien Claimholders and (z) to any "carve out"
provided to any DIP Financing lenders in connection with the DIP Financing, and
will not request adequate protection or any other relief in connection therewith
(except, as expressly agreed by the First Lien Collateral Agent or to the extent
permitted by Section 6.3).

            6.2 Relief from the Automatic Stay. Until the Discharge of First
Lien Obligations has occurred, the Parity Lien Collateral Agent, on behalf of
itself and the Parity Lien Claimholders, agrees that none of them shall seek (or
support any other Person seeking) relief from the automatic stay or any other
stay in any Insolvency or Liquidation Proceeding in respect of the Collateral,
without the prior written consent of the First Lien Collateral Agent, unless a
motion for adequate protection permitted under Section 6.3 has been denied by
the Bankruptcy Court.

                                       30

<PAGE>

            6.3 Adequate Protection.

            (a) The Parity Lien Collateral Agent, on behalf of itself and the
Parity Lien Claimholders, agrees that none of them shall contest (or support any
other Person contesting):

                  (1) any request by the First Lien Collateral Agent or the
      First Lien Claimholders for adequate protection;

                  (2) any objection by the First Lien Collateral Agent or the
      First Lien Claimholders to any motion, relief, action or proceeding based
      on the First Lien Collateral Agent or the First Lien Claimholders claiming
      a lack of adequate protection; or

                  (3) the payment of interest, fees, expenses or other amounts
      to the First Lien Collateral Agent or any other First Lien Claimholder
      under sections 506(b) or 506(c) of the Bankruptcy Code or otherwise.

            (b) Notwithstanding the foregoing provisions in this Section 6.3, in
any Insolvency or Liquidation Proceeding:

                  (1) if the First Lien Claimholders (or any subset thereof) are
      granted adequate protection in the form of additional collateral in
      connection with any Cash Collateral use or DIP Financing, then the Parity
      Lien Collateral Agent, on behalf of itself or any of the Parity Lien
      Claimholders, may seek or request adequate protection solely in the form
      of a Lien on such additional collateral, which Lien will be subordinated
      to the Liens securing the First Lien Obligations and such Cash Collateral
      use or DIP Financing (and all Obligations relating thereto) on the same
      basis as the other Liens securing the Parity Lien Obligations are so
      subordinated to the First Lien Obligations under this Agreement; and

                  (2) in the event the Parity Lien Collateral Agent, on behalf
      of itself or any of the Parity Lien Claimholders, seeks or requests
      adequate protection in respect of Parity Lien Obligations and such
      adequate protection is granted in the form of additional collateral, then
      the Parity Lien Collateral Agent, on behalf of itself or any of the Parity
      Lien Claimholders, agrees that the First Lien Collateral Agent shall also
      be granted a senior Lien on such additional collateral as security for the
      First Lien Obligations and for any Cash Collateral use or DIP Financing
      provided by the First Lien Claimholders and that any Lien on such
      additional collateral securing the Parity Lien Obligations shall be
      subordinated to the Lien on such collateral securing the First Lien
      Obligations and any such DIP Financing provided by the First Lien
      Claimholders (and all Obligations relating thereto) and to any other Liens
      granted to the First Lien Claimholders as adequate protection on the same
      basis as the other Liens securing the Parity Lien Obligations are so
      subordinated to such First Lien Obligations under this Agreement. Except
      as otherwise expressly set forth in Section 6.1 or in connection with the
      exercise of remedies with respect to the Collateral, nothing herein shall
      limit the rights of the

                                       31

<PAGE>

      Parity Lien Collateral Agent or the Parity Lien Claimholders from seeking
      adequate protection (other than in the form of cash or periodic cash
      payments) with respect to their rights in the Collateral in any Insolvency
      or Liquidation Proceeding.

            6.4 No Waiver. Subject to Sections 3.1(a) and (d), nothing contained
herein shall prohibit or in any way limit the First Lien Collateral Agent or any
First Lien Claimholder from objecting in any Insolvency or Liquidation
Proceeding or otherwise to any action taken by the Parity Lien Collateral Agent
or any of the Parity Lien Claimholders, including the seeking by the Parity Lien
Collateral Agent or any Parity Lien Claimholders of adequate protection or the
asserting by the Parity Lien Collateral Agent or any Parity Lien Claimholders of
any of its rights and remedies under the Parity Lien Documents or otherwise.

            6.5 Avoidance Issues. If any First Lien Claimholder is required in
any Insolvency or Liquidation Proceeding or otherwise to turn over or otherwise
pay to the estate of the Company or any other Grantor any amount paid in respect
of First Lien Obligations (a "RECOVERY"), then such First Lien Claimholders
shall be entitled to a reinstatement of First Lien Obligations with respect to
all such recovered amounts. If this Agreement shall have been terminated prior
to such Recovery, this Agreement shall be reinstated in full force and effect,
and such prior termination shall not diminish, release, discharge, impair or
otherwise affect the obligations of the parties hereto from such date of
reinstatement.

            6.6 Reorganization Securities. If, in any Insolvency or Liquidation
Proceeding, debt obligations of the reorganized debtor secured by Liens upon any
property of the reorganized debtor are distributed pursuant to a plan of
reorganization or similar dispositive restructuring plan, both on account of
First Lien Obligations and on account of Parity Lien Obligations, then, to the
extent the debt obligations distributed on account of the First Lien Obligations
and on account of the Parity Lien Obligations are secured by Liens upon the same
property, the provisions of this Agreement will survive the distribution of such
debt obligations pursuant to such plan and will apply with like effect to the
Liens securing such debt obligations.

            6.7 Post-Petition Interest.

            (a) Neither the Parity Lien Collateral Agent nor any Parity Lien
Claimholder shall oppose or seek to challenge any claim by the First Lien
Collateral Agent or any First Lien Claimholder for allowance in any Insolvency
or Liquidation Proceeding of First Lien Obligations consisting of post-petition
interest, fees or expenses to the extent of the value of any First Lien
Claimholder's Lien, without regard to the existence of the Lien of the Parity
Lien Collateral Agent on behalf of the Parity Lien Claimholders on the
Collateral.

            (b) Neither the First Lien Collateral Agent nor any other First Lien
Claimholder shall oppose or seek to challenge any claim by the Parity Lien
Collateral Agent or any Parity Lien Claimholder for allowance in any Insolvency
or Liquidation Proceeding of Parity Lien Obligations consisting of post-petition
interest, fees or expenses

                                       32

<PAGE>

to the extent of the value of the Lien of the Parity Lien Collateral Agent on
behalf of the Parity Lien Claimholders on the Collateral (after taking into
account the First Lien Collateral).

            6.8 Waiver. The Parity Lien Collateral Agent, for itself and on
behalf of the Parity Lien Claimholders, waives any claim it may hereafter have
against any First Lien Claimholder arising out of the election of any First Lien
Claimholder of the application of Section 1111(b)(2) of the Bankruptcy Code,
and/or out of any cash collateral or financing arrangement or out of any grant
of a security interest in connection with the Collateral in any Insolvency or
Liquidation Proceeding.

            6.9 Separate Grants of Security and Separate Classification. The
Parity Lien Collateral Agent, for itself and on behalf of the Parity Lien
Claimholders, and the First Lien Collateral Agent for itself and on behalf of
the First Lien Claimholders, acknowledges and agrees that:

            (a) the grants of Liens pursuant to the First Lien Collateral
Documents and the Parity Lien Collateral Documents constitute two separate and
distinct grants of Liens; and (b) because of, among other things, their
differing rights in the Collateral, the Parity Lien Obligations are
fundamentally different from the First Lien Obligations and must be separately
classified in any plan of reorganization proposed or adopted in an Insolvency or
Liquidation Proceeding.

To further effectuate the intent of the parties as provided in the immediately
preceding sentence, if it is held that the claims of the First Lien Claimholders
and the Parity Lien Claimholders in respect of the Collateral constitute only
one secured claim (rather than separate classes of senior and junior secured
claims), then each of the parties hereto hereby acknowledges and agrees that,
subject to Sections 2.1 and 4.2, all distributions shall be made as if there
were separate classes of senior and junior secured claims against the Grantors
in respect of the Collateral (with the effect being that, to the extent that the
aggregate value of the Collateral is sufficient (for this purpose ignoring all
claims held by the Parity Lien Claimholders), the First Lien Claimholders shall
be entitled to receive, in addition to amounts otherwise distributed to them in
respect of principal, pre-petition interest and other claims, all amounts owing
in respect of post-petition interest, including any additional interest payable
pursuant to the First Lien Credit Agreement, arising from or related to a
default, which is disallowed as a claim in any Insolvency or Liquidation
Proceeding) before any distribution is made in respect of the claims held by the
Parity Lien Claimholders with respect to the Collateral, with the Parity Lien
Collateral Agent, for itself and on behalf of the Parity Lien Claimholders,
hereby acknowledging and agreeing to turn over to the First Lien Collateral
Agent, for itself and on behalf of the First Lien Claimholders, amounts
otherwise received or receivable by them to the extent necessary to effectuate
the intent of this sentence (with respect to the payment of post-petition
interest), even if such turnover has the effect of reducing the claim or
recovery of the Parity Lien Claimholders.

            SECTION 7. RELIANCE; WAIVERS; ETC.

            7.1 Reliance. Other than any reliance on the terms of this
Agreement, the First Lien Collateral Agent, on behalf of itself and the First
Lien Claimholders under its First Lien Loan Documents, acknowledges that it and
such First Lien Claimholders have, independently and without reliance on the
Parity Lien Collateral Agent or any Parity Lien Claimholders, and based on
documents and information deemed by them appropriate, made their own credit
analysis and decision to enter into such First Lien Loan Documents and be bound
by the terms of this Agreement and they will continue to make their own credit
decision in taking or not taking any action under the First Lien Credit
Agreement or this Agreement. The Parity Lien Collateral Agent, on behalf of
itself and the Parity Lien Claimholders, acknowledges that it and the Parity
Lien Claimholders have, independently and without reliance on the First Lien
Collateral Agent or any First Lien Claimholder, and based on documents and
information deemed by them appropriate, made their own credit analysis and
decision to enter into each of the Parity Lien Documents and be bound by the
terms of this Agreement and they will continue to make their own credit decision
in taking or not taking any action under the Parity Lien Documents or this
Agreement.

            7.2 No Warranties or Liability. The First Lien Collateral Agent, on
behalf of itself and the First Lien Claimholders under the First Lien Loan
Documents, acknowledges and agrees that each of the Parity Lien Collateral Agent
and the Parity Lien Claimholders have made no express or implied representation
or warranty, including with respect to the execution, validity, legality,
completeness, collectibility or enforceability of any of the Parity Lien
Documents, the ownership of any Collateral or the perfection or priority of any
Liens thereon. Except as otherwise provided herein, the Parity Lien Claimholders
will be entitled to manage and supervise their respective loans and extensions
of credit under the Parity Lien Documents in accordance with law and as they may
otherwise, in their sole discretion, deem appropriate. Except as otherwise
provided herein, the Parity Lien Collateral Agent, on behalf of itself and the
Parity Lien Claimholders, acknowledges and agrees that the First Lien Collateral
Agent and the First Lien Claimholders have made no express or implied
representation or warranty, including with respect to the execution, validity,
legality, completeness, collectibility or enforceability of any of the First
Lien Loan Documents, the ownership of any Collateral or the perfection or
priority of any Liens thereon. Except as otherwise provided herein, the First
Lien Claimholders will be entitled to manage and supervise their respective
loans and extensions of credit under their respective First Lien Loan Documents
in accordance with law and as they may otherwise, in their sole discretion, deem
appropriate. The Parity Lien Collateral Agent and the Parity Lien Claimholders
shall have no duty to the First Lien Collateral Agent or any of the First Lien
Claimholders, and the First Lien Collateral Agent and the First Lien
Claimholders shall have no duty to the Parity Lien Collateral Agent or any of
the Parity Lien Claimholders, to act or refrain from acting in a manner which
allows, or results in, the occurrence or continuance of an event of default or
default under any agreements with the Company or any other Grantor (including
the First Lien Loan Documents and the Parity Lien Documents), regardless of any
knowledge thereof which they may have or be charged with.

                                       34

            7.3 No Waiver of Lien Priorities.

            (a) No right of the First Lien Claimholders, the First Lien
Collateral Agent or any of them to enforce any provision of this Agreement or
any First Lien Loan Document shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company or any other
Grantor or by any act or failure to act by any First Lien Claimholder or the
First Lien Collateral Agent, or by any noncompliance by any Person with the
terms, provisions and covenants of this Agreement, any of the First Lien Loan
Documents or any of the Parity Lien Documents, regardless of any knowledge
thereof which the First Lien Collateral Agent or the First Lien Claimholders, or
any of them, may have or be otherwise charged with.

            (b) Without in any way limiting the generality of the foregoing
paragraph (but subject to the rights of the Company and the other Grantors under
the First Lien Loan Documents and subject to the provisions of Section 5.3(a)),
the First Lien Claimholders, the First Lien Collateral Agent and any of them
may, at any time and from time to time in accordance with the First Lien Loan
Documents and/or applicable law, without the consent of, or notice to, the
Parity Lien Collateral Agent or any Parity Lien Claimholders, without incurring
any liabilities to the Parity Lien Collateral Agent or any Parity Lien
Claimholders and without impairing or releasing the Lien priorities and other
benefits provided in this Agreement (even if any right of subrogation or other
right or remedy of the Parity Lien Collateral Agent or any Parity Lien
Claimholders is affected, impaired or extinguished thereby) do any one or more
of the following:

                  (1) change the manner, place or terms of payment or change or
      extend the time of payment of, or amend, renew, exchange, increase or
      alter, the terms of any of the First Lien Obligations or any Lien on any
      First Lien Collateral or guaranty thereof or any liability of the Company
      or any other Grantor, or any liability incurred directly or indirectly in
      respect thereof (including any increase in or extension of the First Lien
      Obligations, without any restriction as to the tenor or terms of any such
      increase or extension) or otherwise amend, renew, exchange, extend, modify
      or supplement in any manner any Liens held by the First Lien Collateral
      Agent or any of the First Lien Claimholders, the First Lien Obligations or
      any of the First Lien Loan Documents; provided that any such increase in
      the First Lien Obligations shall not increase the sum of the Indebtedness
      constituting principal under the First Lien Credit Agreement and the face
      amount of any letters of credit issued under the First Lien Credit
      Agreement and not reimbursed to an amount in excess of the Cap Amount;

                  (2) sell, exchange, release, surrender, realize upon, enforce
      or otherwise deal with in any manner and in any order any part of the
      First Lien Collateral or any liability of the Company or any other Grantor
      to the First Lien Claimholders or the First Lien Collateral Agent, or any
      liability incurred directly or indirectly in respect thereof;

                  (3) settle or compromise any First Lien Obligation or any
      other liability of the Company or any other Grantor or any security
      therefor or any

                                       35

<PAGE>

      liability incurred directly or indirectly in respect thereof and apply any
      sums by whomsoever paid and however realized to any liability (including
      the First Lien Obligations) in any manner or order; and

                  (4) exercise or delay in or refrain from exercising any right
      or remedy against the Company or any security or any other Grantor or any
      other Person, elect any remedy and otherwise deal freely with the Company,
      any other Grantor or any First Lien Collateral and any security and any
      guarantor or any liability of the Company or any other Grantor to the
      First Lien Claimholders or any liability incurred directly or indirectly
      in respect thereof.

            (c) Except as otherwise provided herein, the Parity Lien Collateral
Agent, on behalf of itself and the Parity Lien Claimholders, also agrees that
the First Lien Claimholders and the First Lien Collateral Agent shall have no
liability to the Parity Lien Collateral Agent or any Parity Lien Claimholders,
and the Parity Lien Collateral Agent, on behalf of itself and the Parity Lien
Claimholders, hereby waives any claim against any First Lien Claimholder or the
First Lien Collateral Agent, arising out of any and all actions which the First
Lien Claimholders or the First Lien Collateral Agent may take or permit or omit
to take with respect to:

                  (1) the First Lien Loan Documents (other than this Agreement);

                  (2) the collection of the First Lien Obligations; or

                  (3) the foreclosure upon, or sale, liquidation or other
      disposition of, any First Lien Collateral. The Parity Lien Collateral
      Agent, on behalf of itself and the Parity Lien Claimholders, agrees that
      the First Lien Claimholders and the First Lien Collateral Agent have no
      duty to them in respect of the maintenance or preservation of the First
      Lien Collateral, the First Lien Obligations or otherwise.

            (d) Until the Discharge of First Lien Obligations, the Parity Lien
Collateral Agent, on behalf of itself and the Parity Lien Claimholders, agrees
not to assert and hereby waives, to the fullest extent permitted by law, any
right to demand, request, plead or otherwise assert or otherwise claim the
benefit of, any marshalling, appraisal, valuation or other similar right that
may otherwise be available under applicable law with respect to the Collateral
or any other similar rights a junior secured creditor may have under applicable
law.

            7.4 Obligations Unconditional. All rights, interests, agreements and
obligations of the First Lien Collateral Agent and the First Lien Claimholders
and the Parity Lien Collateral Agent and the Parity Lien Claimholders,
respectively, hereunder shall remain in full force and effect irrespective of:

            (a) any lack of validity or enforceability of any First Lien Loan
Documents or any Parity Lien Documents;

            (b) except as otherwise expressly set forth in this Agreement, any
change in the time, manner or place of payment of, or in any other terms of, all
or any of

                                       36

<PAGE>

the First Lien Obligations or Parity Lien Obligations, or any amendment or
waiver or other modification, including any increase in the amount thereof,
whether by course of conduct or otherwise, of the terms of any First Lien Loan
Document or any Parity Lien Document;

            (c) except as otherwise expressly set forth in this Agreement, any
exchange of any security interest in any Collateral or any other collateral, or
any amendment, waiver or other modification, whether in writing or by course of
conduct or otherwise, of all or any of the First Lien Obligations or Parity Lien
Obligations or any guaranty thereof;

            (d) the commencement of any Insolvency or Liquidation Proceeding in
respect of the Company or any other Grantor; or

            (e) any other circumstances which otherwise might constitute a
defense available to, or a discharge of, the Company or any other Grantor in
respect of the First Lien Collateral Agent, the First Lien Obligations, any
First Lien Claimholder, the Parity Lien Collateral Agent, the Parity Lien
Obligations or any Parity Lien Claimholder in respect of this Agreement.

            SECTION 8. MISCELLANEOUS.

            8.1 Conflicts. In the event of any conflict between the provisions
of this Agreement and the provisions of the First Lien Loan Documents or the
Parity Lien Documents, the provisions of this Agreement shall govern and
control.

            8.2 Effectiveness; Continuing Nature of this Agreement;
Severability. This Agreement shall become effective when executed and delivered
by the parties hereto. This is a continuing agreement of lien subordination and
the First Lien Claimholders may continue, at any time and without notice to the
Parity Lien Collateral Agent or any Parity Lien Claimholder subject to the
Parity Lien Documents, to extend credit and other financial accommodations and
lend monies to or for the benefit of the Company or any Grantor constituting
First Lien Obligations in reliance hereof. The Parity Lien Collateral Agent, on
behalf of itself and the Parity Lien Claimholders, hereby waives any right it
may have under applicable law to revoke this Agreement or any of the provisions
of this Agreement. The terms of this Agreement shall survive, and shall continue
in full force and effect, in any Insolvency or Liquidation Proceeding. Any
provision of this Agreement that is prohibited or unenforceable in any
jurisdiction shall not invalidate the remaining provisions hereof, and any such
prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction. All references to
the Company or any other Grantor shall include the Company or such Grantor as
debtor and debtor-in-possession and any receiver or trustee for the Company or
any other Grantor (as the case may be) in any Insolvency or Liquidation
Proceeding. This Agreement shall terminate and be of no further force and
effect:

            (a) with respect to the First Lien Collateral Agent, the First Lien
Claimholders and the First Lien Obligations, the date of Discharge of First Lien
Obligations, subject to the rights of the First Lien Claimholders under Section
6.5; and

                                       37

<PAGE>

            (b) with respect to the Parity Lien Collateral Agent, the Parity
Lien Claimholders and the Parity Lien Obligations, upon the later of (1) the
date upon which the obligations under each of the Parity Lien Documents
terminate if there are no other Parity Lien Obligations outstanding on such date
and (2) if there are other Parity Lien Obligations outstanding on such date, the
date upon which such Parity Lien Obligations terminate.

            8.3 Amendments; Waivers.

            (a) No amendment, modification or waiver of any provision of this
Agreement shall be effective unless the same shall be in writing signed by the
First Lien Collateral Agent, the Parity Lien Collateral Agent and (except as
provided in clause (c) below) the Company, at the written direction of the
Required Parity Lien Claimholders, except no amendment or modification that
reduces, impairs or adversely affects the rights of any First Lien Claimholder
or Parity Lien Claimholder to (1) vote its Secured Debt as to any matter
described in this Agreement as being subject to its vote or consent (or amends
the definition of "Required Parity Lien Claimholders"), (2) share in the order
of application of proceeds described in Section 4.2 or (3) require that Liens
securing First Lien Obligations and Parity Lien Obligations be released only as
set forth in the provisions described in Section 5.1 will be effective without
the consent of the requisite percentage or number of holders of the applicable
Secured Debt so affected under the applicable First Lien Collateral Document or
Parity Lien Collateral Document.

            (b) Each waiver, if any shall be a waiver only with respect to the
specific instance involved and shall in no way impair the rights of the parties
making such waiver or the obligations of the other parties to such party in any
other respect or at any other time.

            (c) Notwithstanding the foregoing, the Company shall not have any
right to consent to or approve any amendment, modification or waiver of any
provision of this Agreement except to the extent its rights or obligations are
affected thereby (which includes, but is not limited to any amendment to the
Grantor's ability to cause additional obligations to constitute First Lien
Obligations or Parity Lien Obligations as the Company may designate).

            (d) Any consent, amendment, modification or waiver entered into in
accordance with this Section 8.2 shall be binding upon the parties hereto, all
First Lien Claimholders, all Parity Lien Claimholders and any co-trustees,
agents or sub-agents thereof.

            8.4 Information Concerning Financial Condition of the Company and
its Subsidiaries. The First Lien Collateral Agent and the First Lien
Claimholders, on the one hand, and the Parity Lien Collateral Agent and the
Parity Lien Claimholders, on the other hand, shall each be responsible for
keeping themselves informed of (a) the financial condition of the Company and
its Subsidiaries and all endorsers and/or guarantors of the First Lien
Obligations or the Parity Lien Obligations and (b) all other circumstances
bearing upon the risk of nonpayment of the First Lien Obligations or the Parity
Lien Obligations. The First Lien Collateral Agent and the First Lien
