      Section 2. Lien Priorities.

attachment or perfection of any Liens granted to the Trustee or the Noteholders
on the Common Collateral or of any Liens granted to the Senior Agent or the
Senior Lenders on the Common Collateral and notwithstanding any provision of the
UCC, or any applicable law or the Noteholder Documents or the Senior Lender
Documents or any other circumstance whatsoever, the Trustee, on behalf of
itself, the trustee under the Indenture and the Noteholders, hereby agrees that:
(a) any Lien on the Common Collateral securing the First Priority Lien
Obligations now or hereafter held by the Senior Agent or the Senior Lenders
shall be senior and prior to any Lien on the Common Collateral securing the
Obligations; and (b) any Lien on the Common Collateral now or hereafter held by
the Trustee or the Noteholders regardless of how acquired, whether by grant,
statute, operation of law, subrogation or otherwise, shall be junior and
subordinate in all respects to all Liens on the Common Collateral securing the
First Priority Lien Obligations. All Liens on the Common Collateral securing the
First Priority Lien Obligations shall be and remain senior to all Liens on the
Common Collateral securing the Obligations for all purposes, whether or not such
Liens securing the First Priority Lien Obligations are subordinated to any Lien
securing any other obligation of the Borrowers or their Subsidiaries.

      2.2 Prohibition on Contesting Liens. Each of the Trustee, for itself and
on behalf of each Noteholder, and the Senior Agent, for itself and on behalf of
each Senior Lender, agrees that it shall not (and hereby waives any right to)

Senior Agent or the Senior Lenders in the Senior Lender Collateral or by the
Noteholders in the Common Collateral, as the case may be.


                                       4
<PAGE>
      2.3 No New Liens. So long as the Discharge of First Priority Lien
Obligations has not occurred, (a) the parties hereto agree that, after the date
hereof, if the Trustee shall hold any Lien on any assets of the Borrowers or
their Subsidiaries securing the Obligations that are not also subject to the
First Priority Liens of the Senior Agent under the Senior Lender Documents, the
Trustee, upon demand by the Senior Agent, will either release such Lien or
assign it to the Senior Agent as security for the First Priority Lien
Obligations, (b) the parties hereto agree that, after the date hereof, if the
Senior Agent shall hold any Lien on any assets of the Borrowers securing the
First Priority Lien Obligations that are not also subject to the second-priority
Lien of the Trustee under the Noteholder Documents, the Borrowers shall grant a
second-priority Lien on such assets to the Trustee as security for the
Obligations, and (c) the Borrowers agree not to grant or to permit any of their
Subsidiaries to grant any Lien on any of their assets in favor of the Trustee or
the Noteholders unless such Borrower, or Subsidiary, has granted a similar Lien
on such assets in favor of the Senior Agent or the Senior Lenders.

      Section 3. Enforcement.

      3.1 Exercise of Remedies.

            (a) So long as the Discharge of First Priority Lien Obligations has
not occurred, whether or not any Insolvency or Liquidation Proceeding has been
commenced by or against any Borrower of any Subsidiary of a Borrower, (i) the
Trustee and the Noteholders will not exercise or seek to exercise any rights or
remedies (including setoff) with respect to any Common Collateral, institute any
action or proceeding with respect to such rights or remedies, including, without
limitation, any action of foreclosure, contest, protest or object to any
foreclosure proceeding or action brought by the Senior Agent or any Senior
Lender, or any other exercise by any such party, of any rights and remedies
relating to the Common Collateral under the Senior Lender Documents or
otherwise, or object to the forbearance by the Senior Lenders from bringing or
pursuing any foreclosure proceeding or action or any other exercise of any
rights or remedies relating to the Common Collateral and (ii) the Senior Agent
and the Senior Lenders shall have the exclusive right to enforce rights,
exercise remedies (including, without limitation, setoff and the right to credit
bid their debt) and make determinations regarding release, disposition, or
restrictions with respect to the Common Collateral without any consultation with
or the consent of the Trustee or any Noteholder (and the Trustee and Noteholders
shall be deemed to have consented to any such enforcement, exercise or
determination); provided, however, (A) that in any Insolvency or Liquidation
Proceeding commenced by or against a Borrower or any Subsidiary of a Borrower,
the Trustee may file a claim or statement of interest with respect to the
Obligations, and (B) the Trustee may take any action not adverse to the Liens on
the Common Collateral securing the Senior Lender Claims in order to preserve or
protect its rights in the Common Collateral. In exercising rights and remedies
with respect to the Common Collateral, the Senior Agent and the Senior Lenders
may enforce the provisions of the Senior Lender 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,
without limitation, the rights of an agent appointed by them to sell or
otherwise dispose of Common Collateral upon foreclosure, to incur expenses in
connection with such sale or disposition, and to exercise all the rights and
remedies of a


                                       5
<PAGE>
secured lender under the Uniform Commercial Code of any applicable jurisdiction
and of a secured creditor under bankruptcy or similar laws of any applicable
jurisdiction. The Trustee and the Noteholders waive any rights they may have to
require the Senior Agent or Senior Lenders to marshall assets.

            (b) The Trustee, on behalf of itself and the Noteholders, agrees
that it will not take or receive any Common Collateral or any proceeds of Common
Collateral in connection with the exercise of any right or remedy (including
setoff) with respect to any Common Collateral, unless and until the Discharge of
First Priority Lien Obligations has occurred. Without limiting the generality of
the foregoing, unless and until the Discharge of First Priority Lien Obligations
has occurred, except as expressly provided in the proviso in Section 3.1(a) (ii)
above, the sole right of the Trustee and the Noteholders with respect to the
Common Collateral is to hold a Lien on the Common Collateral pursuant to the
Noteholder 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
Priority Lien Obligations has occurred.

            (c) Subject to the proviso in Section 3.1(a) (ii) above, (a) the
Trustee, for itself or on behalf of the Noteholders, agrees that the Trustee and
the Noteholders will not take any action that would hinder any exercise of
remedies undertaken by the Senior Agent under the Senior Loan Documents,
including any sale, lease, exchange, transfer or other disposition of the Common
Collateral, whether by foreclosure or otherwise, and (b) the Trustee, for itself
and on behalf of the Noteholders, hereby waives any and all rights it or the
Noteholders may have as a junior lien creditor or otherwise to object to the
manner in which the Senior Agent or the Senior Lenders seek to enforce or
collect the First Priority Lien Obligations or the Liens granted in any of the
Senior Lender Collateral.

      3.2 Cooperation. Subject to the proviso in Section 3.1(a)(ii) above, the
Trustee, on behalf of itself and the Noteholders, agrees that, unless and until
the Discharge of First Priority Lien Obligations has occurred, it will not
commence, or join with any Person (other than the Senior Lenders and the Senior
Agent upon the request thereof) in commencing any enforcement, collection,
execution, levy or foreclosure action or proceeding with respect to any Lien
held by it under any of the Noteholder Documents or otherwise.

      Section 4. Payments.

      4.1 Application of Proceeds. As long as the Discharge of First Priority
Lien Obligations has not occurred, the cash proceeds of Common Collateral
received in connection with the sale of, or collection on, such Common
Collateral upon the exercise of remedies, shall be applied by the Senior Agent
to the First Priority Lien Obligations in such order as specified in the Senior
Facility until Discharge of First Priority Lien Obligations has occurred. Upon
Discharge of the First Priority Lien Obligations, the Senior Agent shall deliver
to the Trustee any proceeds of Common Collateral held by it in the same form as
received, with any necessary endorsements or as a court of competent
jurisdiction may otherwise direct or as may otherwise be required by applicable
law.


                                       6
<PAGE>
      4.2 Payments Over. Any Common Collateral or proceeds thereof received by
the Trustee or any Noteholder in connection with the exercise of any right or
remedy (including setoff) relating to the Common Collateral in contravention of
this Agreement shall be segregated and held in trust and forthwith paid over to
the Senior Agent for the benefit of the Senior Lenders in the same form as
received, with any necessary endorsements or as a court of competent
jurisdiction may otherwise direct. The Senior Agent is hereby authorized to make
any such endorsements as agent for the Trustee or any such Noteholder. This
authorization is coupled with an interest and is irrevocable.

      Section 5. Other Agreements.

      5.1 Releases.

            (a) If in connection with:

                  (i) the exercise of the Senior Agent's rights or remedies in
            respect of the Common Collateral provided for in Section 3.1,
            including any sale, lease, exchange, transfer or other disposition
            of such Common Collateral;

                  (ii) any sale, lease, exchange, transfer or other disposition
            of Common Collateral permitted under the terms of the Senior
            Facility (whether or not an event of default under, and as defined
            therein, has occurred and is continuing); or

                  (iii) any agreement between the Senior Agent and the Borrowers
            to release the Senior Agent's Lien on any portion of the Common
            Collateral, which release is not otherwise prohibited by the terms
            of the Noteholder Documents;

the Senior Agent, for itself or on behalf of any of the Senior Lenders, releases
any of its Liens on any part of the Common Collateral, the Liens, if any, of the
Trustee, for itself or for the benefit of the Noteholders, on such Common
Collateral shall be automatically, unconditionally and simultaneously released
and the Trustee, for itself or on behalf of any such Noteholder, promptly shall
execute and deliver to the Senior Agent or the Borrowers such termination
statements, releases and other documents as the Senior Agent or the Borrowers
may request to effectively confirm such release provided, however, that if an
Event of Default (as defined in the Indenture) exists as of the date of
Discharge of First Priority Lien Obligations, the Liens, if any, of the Trustee,
for itself or for the benefit of the Noteholders, on such Common Collateral
shall not be released until such Event of Default and all other Events of
Default shall have been cured or otherwise waived except to the extent such
Common Collateral was disposed of in order to repay the First Priority Lien
Obligations.

            (b) The Trustee, for itself and on behalf of the Noteholders, hereby
irrevocably constitutes and appoints the Senior 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 the Trustee or such holder or in
the Senior Agent's own name, from time to time in the Senior Agent's discretion,
for the purpose of carrying out the terms of this Section 5.1, to take any and


                                       7
<PAGE>
all appropriate action and to execute and file or record any and all documents
and instruments which may be necessary or desirable to accomplish the purposes
of this Section 5.1, including, without limitation, any termination statements,
endorsements or other instruments or transfer or release.

      5.2 Insurance. Unless and until the Discharge of First Priority Lien
Obligations has occurred, the Senior Agent and the Senior Lenders shall have the
sole and exclusive right, subject to the rights of the Borrowers under the
Senior Lender Documents, to adjust settlement for any insurance policy covering
the Common Collateral in the event of any loss thereunder and to approve any
award granted in any condemnation or similar proceeding affecting the Common
Collateral. Unless and until the Discharge of First Priority Lien Obligations
has occurred, all proceeds of any such policy and any such award if in respect
to the Common Collateral shall be paid to the Senior Agent for the benefit of
the Senior Lenders to the extent required under the Senior Facility and
thereafter to the Trustee for the benefit of the Noteholders to the extent
required under the applicable Noteholder Documents and then to the owner of the
subject property or as a court of competent jurisdiction may otherwise direct or
as may otherwise be required by applicable law. If the Trustee or any Noteholder
shall, at any time, receive any proceeds of any such insurance policy or any
such award in contravention of this Agreement, it shall pay such proceeds over
to the Senior Agent in accordance with the terms of Section 4.2.

      5.3 Amendments to Noteholder Collateral Documents.

            (a) Without the prior written consent of the Senior Agent and the
Required Lenders, no Noteholder Collateral Document may be amended, supplemented
or otherwise modified or entered into to the extent such amendment, supplement
or modification, or the terms of any new Noteholder Collateral Document, would
be inconsistent with any of the terms of the Senior Lender Documents.

            (b) In the event the Senior Agent or the Senior Lenders enter into
any amendment, waiver or consent in respect of any of the Senior Lender
Collateral Documents for the purpose of adding to, or deleting from, or waiving
or consenting to any departures from any provisions of, any Senior Lender
Collateral Document or changing in any manner the rights of the Senior Agent,
the Senior Lenders, or the Borrowers thereunder, then such amendment, waiver or
consent shall apply automatically to any comparable provision of the Comparable
Noteholder Collateral Document without the consent of the Trustee or the
Noteholders and without any action by the Trustee, the Noteholders or the
Borrowers; provided, however, (A) that no such amendment, waiver or consent
shall have the effect of removing assets subject to the Lien of the Noteholder
Collateral Documents, except to the extent that a release of such Lien is
permitted by Section 5.1 and (B) notice of such amendment, waiver or consent
shall have been given to the Trustee.

      5.4 Rights As Unsecured Creditors. Notwithstanding anything to the
contrary in this Agreement, and subject to Article IV of the Indenture, the
Trustee and the Noteholders may exercise rights and remedies as an unsecured
creditor against the Borrowers and their Subsidiaries in accordance with the
terms of the Noteholder Documents and applicable law. Nothing in this Agreement
shall prohibit the receipt by the Trustee or any Noteholders of the


                                       8
<PAGE>
required payments of interest and principal so long as such receipt is permitted
by Article IV of the Indenture and is not the direct or indirect result of the
exercise by the Trustee or any Noteholder of rights or remedies as a secured
creditor or enforcement of any Lien held by any of them in contravention of this
Agreement. In the event the Trustee or any Noteholder becomes a judgment lien
creditor in respect of Common Collateral as a result of its enforcement of its
rights as an unsecured creditor, such judgment lien shall be subordinated to the
Liens securing First Priority Lien Obligations on the same basis as the other
Liens securing the Obligations are so subordinated to such First Priority Lien
Obligations under this Agreement. Nothing in this Agreement modifies any rights
or remedies (x) the Senior Agent or the Senior Lenders may have with respect to
the Senior Lender Collateral or (y) except as expressly set forth herein, the
Trustee or the Noteholder may have with respect to the Noteholder Collateral.
The provisions of this Agreement are in addition to, and not in derogation of,
Article IV of the Indenture.

      5.5 Bailee for Perfection.

            (a) The Senior Agent agrees to hold the Collateral that is part of
the Common Collateral in its possession or control (or in the possession or
control of its agents or bailees) as bailee for the Trustee and any assignee
solely for the purpose of perfecting the security interest granted in such
Collateral pursuant to the Noteholder Security Agreement, subject to the terms
and conditions of this Section 5.5.

            (b) Until the Discharge of First Priority Lien Obligations has
occurred, the Senior Agent shall be entitled to deal with the Collateral in its
possession or control in accordance with the terms of the Senior Lender
Collateral Documents as if no bailee arrangement with the Trustee existed. The
rights of the Trustee shall at all times be subject to the terms of this
Agreement and to the Senior Agent's rights under the Senior Lender Documents.

            (c) The Senior Agent shall have no obligation whatsoever to the
Trustee or any Noteholder to assure that the Collateral in its possession or
control is genuine or owned by the Borrowers or one of their Subsidiaries or to
preserve rights or benefits of any Person except as expressly set forth in this
Section 5.5. The duties or responsibilities of the Senior Agent under this
Section 5.5 shall be limited solely to holding the Collateral in its possession
or control as bailee for the Trustee for purposes of perfecting the Lien held by
the Trustee.

            (d) The Senior Agent shall not have by reason of the Noteholder
Security Agreement or this Agreement or any other document a fiduciary
relationship in respect of the Trustee or any Noteholder.

            (e) Upon the Discharge of First Priority Lien Obligations, the
Senior Agent shall deliver to the Trustee the Collateral in its possession or
control together with any necessary endorsements (or otherwise allow the Trustee
to obtain control of such Collateral) or as a court of competent jurisdiction
may otherwise direct or as may otherwise be required by applicable law.

      Section 6. Insolvency or Liquidation Proceedings.


                                       9
<PAGE>
      6.1 Financing Issues. If any Borrower or any Subsidiary of a Borrower
shall be subject to any Insolvency or Liquidation Proceeding and the Senior
Agent shall desire to permit the use of cash collateral or to permit such
Borrower or Subsidiary to obtain financing under section 363 or section 364 of
the Bankruptcy Code ("DIP Financing"), then the Trustee, on behalf of itself and
the Noteholders, agrees that it will raise no objection to such use or DIP
Financing and will not request adequate protection or any other relief in
connection therewith (except to the extent permitted by Section 6.3) and, to the
extent the Liens securing the First Priority Lien Obligations are subordinated
or pari passu with such DIP Financing, will subordinate its Liens in the Common
Collateral to such DIP Financing (and all obligations relating thereto) on the
same basis as the other Liens securing the Obligations are so subordinated to
First Priority Lien Obligations under this Agreement.

      6.2 Relief from the Automatic Stay. Until the Discharge of First Priority
Lien Obligations has occurred, the Trustee, on behalf of itself and the
Noteholders, agrees that none of them shall seek relief from the automatic stay
or any other stay in any Insolvency or Liquidation Proceeding in respect of the
Common Collateral, without the prior written consent of the Senior Agent and the
Required Lenders.

      6.3 Adequate Protection. The Trustee, on behalf of itself and the
Noteholders, agrees that none of them shall contest (or support any other Person
contesting) (a) any request by the Senior Agent or the Senior Lenders for
adequate protection or (b) any objection by the Senior Agent or the Senior
Lenders to any motion, relief, action or proceeding based on the Senior Agent or
the Senior Lenders claiming a lack of adequate protection. Notwithstanding the
foregoing contained in this Section 6.3, in any Insolvency or Liquidation
Proceeding, (i) if the Senior Lenders (or any subset thereof) are granted
adequate protection in the form of additional collateral in connection with any
DIP Financing or use of its cash collateral under section 363 or section 364 of
the Bankruptcy Code, then the Trustee, on behalf of itself or any of the
Noteholders, may seek or request adequate protection in the form of a
replacement Lien on such additional collateral, which Lien is subordinated to
the Liens securing the First Priority Lien Obligations and such DIP Financing
(and all obligations relating thereto) on the same basis as the other Liens
securing the Obligations are so subordinated to the First Priority Lien
Obligations under this Agreement, and (ii) in the event the Trustee, on behalf
of itself and the Noteholders, seeks or requests adequate protection and such
adequate protection is granted in the form of additional collateral, then the
Trustee, on behalf of itself or any of the Noteholders, agrees that the Senior
Agent shall also be granted a senior Lien on such additional collateral as
security for the First Priority Lien Obligations and any such DIP Financing and
that any Lien on such additional collateral securing the Obligations shall be
subordinated to the Liens on such collateral securing the First Priority Lien
Obligations and any such DIP Financing (and all obligations relating thereto)
and any other Liens granted to the Senior Lenders as adequate protection on the
same basis as the other Liens securing the Obligations are so subordinated to
such First Priority Lien Obligations under this Agreement.

      6.4 No Waiver. Nothing contained herein shall prohibit or in any way limit
the Senior Agent or any Senior Lender from objecting in any Insolvency or
Liquidation Proceeding or otherwise to any action taken by the Trustee or any of
the Noteholders, including, without limitation, the seeking by the Trustee or
any Noteholder of adequate protection or the asserting

by the Trustee or any Noteholder of any of its rights and remedies under the
Noteholder Documents or otherwise.

      6.5 Preference Issues. If any Senior Lender is required in any Insolvency
or Liquidation Proceeding or otherwise to turn over or otherwise pay to the
estate of a Borrower or any Subsidiary of a Borrower any amount (a "Recovery"),
then the First Priority Lien Obligations shall be reinstated to the extent of
such Recovery and the Senior Lenders shall be entitled to a Discharge of First
Priority 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.

Documents or this Agreement.

      7.2 No Warranties or Liability. (a) The Trustee, on behalf of itself and

have in the Common Collateral or otherwise, except as otherwise provided in this
Agreement. Neither the Senior Agent nor any Senior Lender shall have any duty to

enforceability of any of the Noteholder Documents.

      7.3 No Waiver of Lien Priorities.

            (a) No right of the Senior Lenders, the Senior Agent or any of them
to enforce any provision of this Agreement shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Borrowers
or by any act or failure to act by any Senior Lender or the Senior Agent, or by
any noncompliance by any Person with the terms, provisions and covenants of this
Agreement, any of the Senior Lender Documents or any of the Noteholder
Documents, regardless of any knowledge thereof which the Senior Agent or the
Senior Lenders, 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 Borrowers under the Senior Lender
Documents), the Senior Lenders, the Senior Agent and any of them, may, at any
time and from time to time, without the consent of, or notice to, the Trustee or
any Noteholder, without incurring any liabilities to the Trustee or any

extinguished thereby) do any one or more of the following:

            any Senior Lender Collateral or guaranty thereof or any liability of
            the Borrowers, or any liability incurred directly or indirectly in
            respect thereof (including, without limitation, any increase in or
            extension of the First Priority Lien Obligations, without any
            restriction as to the amount, 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 Senior Lenders, the
            First Priority Lien Obligations or any of the Senior Lender
            Documents;

                  (ii) sell, exchange, release, surrender, realize upon, enforce
            or otherwise deal with in any manner and in any order any part of
            the Senior Lender Collateral or any liability of the Borrowers or
            their Subsidiaries to the Senior Lenders or the Senior Agent, or any

            or any other liability of the Borrowers or their Subsidiaries or any
            security therefor or any liability incurred directly or indirectly
            in respect thereof and apply any sums by whomsoever paid and however
            realized to any liability (including, without limitation, the First
            Priority Lien Obligations) in any manner or order; and


                                       12

                  (iv) exercise or delay in or refrain from exercising any right
            or remedy against the Borrowers or their Subsidiaries or any
            security or any other Person, elect any remedy and otherwise deal
            freely with the Borrowers or their Subsidiaries and the Senior
            Lender Collateral and any security and any guarantor or any
            liability of the Borrowers or any guarantor to the Senior Lenders or
            any liability incurred directly or indirectly in respect thereof;

            (c) The Trustee, on behalf of itself and the Noteholders, also
agrees that the Senior Lenders and the Senior Agent shall have no liability to
the Trustee or any Noteholder, and the Trustee, on behalf of itself and the
Noteholders, hereby waives any claim against any Senior Lender or the Senior
Agent, arising out of any and all actions which the Senior Lenders or the Senior
Agent may take or permit or omit to take with respect to: (i) the Senior Lender
Documents, (ii) the collection of the First Priority Lien Obligations, or (iii)
the foreclosure upon, or sale, liquidation or other disposition of, the Senior
Lender Collateral. The Trustee, on behalf of itself and the Noteholders, agrees

the maintenance or preservation of the Senior Lender Collateral, the First
Priority Lien Obligations or otherwise; and

            (d) The Trustee, on behalf of itself and the Noteholders, 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 or any other similar rights a junior secured
creditor may have under applicable law.

conduct or otherwise, of the terms of the Senior Facility or any other Senior
Lender Document or of the terms of the Indenture or any other Noteholder
Document;

            (c) any exchange of any security interest in any Common Collateral

defense available to, or a discharge of, any Borrower or any Subsidiary of a
Borrower in respect of the First Priority Lien Obligations, or of the Trustee or
any Noteholder in respect of this Agreement.

      Section 8. Miscellaneous.

Borrowers shall not have any right to amend, modify or waive any provision of
this Agreement without the consent of the Trustee or the Senior Agent, as

to effect any amendment, modification or waiver of any provision of this
Agreement, except that no amendment, modification or waiver affecting any
obligation or right of the Borrowers hereunder shall be made without the consent
of the Borrowers.
