                                       5



Loan Documents or any other circumstance whatsoever, the Trustee, on behalf of
itself and the Noteholders, hereby agrees that: (i) any Lien on the Common
Collateral securing the Lender Claims now or hereafter held by the Secured
Parties shall be first in priority to any Lien on the Common Collateral
securing the Noteholder Claims; and (ii) 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
second in priority in all respects to all Liens on the Common Collateral
securing the Lender Claims. All Liens on the Common Collateral securing the

Collateral securing the Noteholder Claims for all purposes, whether or not such
Lender Liens are subordinated to any Lien securing any other obligation of any
Obligor.

     SECTION 2.2 Prohibition on Contesting Liens. Each of the Trustee, for
itself and on behalf of each Noteholder, and the Administrative Agent, for
itself and on behalf of each other Secured Party, agrees that it shall 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
priority, validity or enforceability of a Lien held by the Secured Parties in
the Lender Collateral or by the Noteholders in the Common Collateral, as the
case may be.

     SECTION 2.3 No New Liens. So long as the Discharge of Lender Claims has
not occurred, (a) the parties hereto agree that, (i) neither the Trustee nor
any Noteholder shall acquire any security interest in and shall have no
interest in (including following avoidance of any Lender Liens) any property,
real or otherwise, of Holdings or any proceeds thereof and (ii) after the date
hereof, if the Trustee shall hold any Lien on any assets of any Obligor
securing the Noteholder Claims that are not also subject to the prior Lien of
the Secured Parties under the Loan Documents, the Trustee will notify the
Administrative Agent in writing and, upon demand by the Administrative Agent,
shall, either release such Lien or assign it to the Secured Parties as security
for the Lender Claims (unless the applicable Obligor shall promptly grant a
similar Lien on such assets in favor of such Secured Parties and such lien
shall be prior to the Lien of the Trustee on such assets) and (b) each Obligor
agrees it will not grant, and the Company agrees it will not permit its
Subsidiaries to grant, any Lien on any of its assets, in favor of the Trustee
or the Noteholders unless such Obligor has granted a similar perfected prior
Lien on such assets in favor of the Secured Parties.

     SECTION 3. Enforcement.

     SECTION 3.1 Exercise of Remedies. (a) So long as the Discharge of Lender
Claims has not occurred, whether or not any Insolvency or Liquidation
Proceeding has been commenced by or against any Obligor, (i) the Trustee and
the Noteholders will not exercise or seek to exercise any rights or remedies
(including by way of setoff) with respect to any Common Collateral, institute
any action or proceeding with respect to such rights or remedies, including any
action of foreclosure, or contest, protest or object to any foreclosure
proceeding or action brought by the Administrative Agent or any other Secured
Party, any exercise of any right under any control agreement in respect of a
deposit account or securities entitlement constituting Common Collateral, or
any bailee's letter or similar agreement or arrangement to which the Trustee or
any Noteholder is a party, or any other exercise by any such party, of any
rights and remedies relating to the Common Collateral under the Loan Documents
or otherwise, or object to the forbearance by the Secured Parties from bringing
or pursuing any foreclosure proceeding or


                                       6



action or any other exercise of any rights or remedies relating to the Common
Collateral and (ii) the Administrative Agent and the other Secured Parties
shall have the exclusive right to enforce rights, exercise remedies (including
by way of setoff and the right to credit bid their debt), refrain from
enforcing or exercising remedies, 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, all as if
the Lien of the Trustee under the Noteholder Collateral Documents did not
exist; provided that (A) in any Insolvency or Liquidation Proceeding commenced
by or against any Obligor, the Trustee or any Noteholder may file a claim or
statement of interest with respect to the Noteholder Claims, (B) the Trustee or
any Noteholder may take any action not adverse to the Liens on the Common
Collateral securing the Lender Claims in order to establish, preserve, perfect
or protect its rights in the Common Collateral, (C) solely to the extent it
would not prevent, restrict or otherwise limit any rights granted or created
hereunder or under any Loan Document in favor of the Administrative Agent or
any other Secured Party in respect of the Common Collateral, the Trustee or any
Noteholder shall be entitled to file any necessary responsive or defensive
pleadings in opposition to any motion, claim, adversary proceeding or other
pleadings made by any person objecting to or otherwise seeking the disallowance
of the Noteholder Claims, including without limitation any claims secured by
the Common Collateral, if any, in each case in accordance with the terms of
this Agreement, or (D) the Trustee or any Noteholder shall be entitled to file
any pleadings, objections, motions or agreements which assert rights or
interests available to unsecured creditors of the Obligors arising under either
the Bankruptcy Code or applicable non-bankruptcy law, in each case in
accordance with the terms of this Agreement. In exercising rights and remedies
with respect to the Common Collateral, the Administrative Agent or any other
Secured Parties may enforce the provisions of the Loan Documents and exercise
remedies thereunder, all in such order and in such manner as it may determine
in the exercise of its sole discretion. Such exercise and enforcement shall
include the rights of an agent appointed by the Administrative Agent and the
other Secured Parties 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 secured party under the UCC of any
applicable jurisdiction and of a secured creditor under bankruptcy or similar
laws of any applicable jurisdiction.

     (b) The Trustee, on behalf of itself and the Noteholders, agrees that it
will not, in connection with the exercise of any right or remedy (including by
way of setoff) with respect to any Common Collateral, take or receive any
Common Collateral or any proceeds of Common Collateral unless and until the
Discharge of Lender Claims has occurred. In the event any such proceeds are
received by the Trustee in violation of this Agreement, such proceeds shall be
segregated and held in trust for the benefit of the Secured Parties in the same
form as received, and shall not be applied to the satisfaction of any
Noteholder Claims unless and until the Discharge of the Lender Claims has
occurred. Without limiting the generality of the foregoing, unless and until
the Discharge of Lender Claims has occurred, except as expressly provided in
the proviso in clause (a)(ii) of Section 3.1, the sole right of the Trustee and
the Noteholders as secured parties with respect to the Common Collateral is to
hold a perfected 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 the Lender Claims
has occurred.

     (c) [Intentionally Omitted]


                                       7



     (d) Subject to the proviso in clause (a)(ii) of Section 3.1, (i) the
Trustee, for itself and on behalf of the Noteholders, agrees that the Trustee
and the Noteholders will not take any action that would hinder or cause to
delay any exercise of remedies undertaken by the Administrative Agent or any
other Secured Party under the Loan Documents as secured parties in respect of
any Common Collateral, including any sale, lease, exchange, transfer or other
disposition of the Common Collateral, whether by foreclosure or otherwise, and
(ii) 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 (whether arising under the UCC or any other law) to object to the
manner in which the Administrative Agent or the other Secured Parties seek to
enforce the Liens granted in any of the Lender Collateral.

     (e) The Trustee hereby acknowledges and agrees that no covenant, agreement
or restriction contained in the Noteholder Collateral Documents or any other
Noteholder Document shall be deemed to restrict in any way the rights and
remedies of the Administrative Agent or the Secured Parties with respect to the
Common Collateral as set forth in this Agreement and the Loan Documents.

     SECTION 3.2 Cooperation. Subject to the proviso in clause (a)(ii) of
Section 3.1, the Trustee, on behalf of itself and the Noteholders, agrees that,
unless and until the Discharge of Lender Claims has occurred, it will not
commence, or join with any Person (other than the Secured Parties 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.

     SECTION 4. Application of Proceeds. As long as the Discharge of Lender
Claims 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 Administrative Agent to the
Lender Claims in such order as specified in the Credit Agreement and any Future
First-Lien Credit Facility until the Discharge of Lender Claims has occurred.
Upon the Discharge of the Lender Claims, the Administrative Agent shall deliver
to the Trustee (for application in such order as specified in the Indenture and
the other applicable Noteholder Documents) 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.

     SECTION 5. Other Agreements.

     SECTION 5.1 Releases.

     (a) At such time as:

          (i) the Discharge of the Lender Claims; or

          (ii) the Secured Parties have released the Lender Liens on all or any
     portion of the Common Collateral,

the Liens granted to the Trustee or the Noteholders on the Common Collateral
(or, in the case of a release of the Lender Liens referred to in clause (a)(ii)
on only a portion of the Common Collateral, the portion of the Common
Collateral in respect of which the Lender Liens were


                                       8



released) shall be automatically, unconditionally and simultaneously released
and the Trustee, for itself and on behalf of the Noteholders, promptly shall
execute and deliver to the Administrative Agent and the Company such
termination statements, releases and other documents as the Administrative
Agent and the Company may request to effectively confirm such release; provided
that, (A) in the case of clause (a)(i), in the event that an event of default
under the Indenture or any other Noteholder Document has occurred and is
continuing as of the date on which the Discharge of Lender Claims occurs, the
Liens granted to the Trustee or the Noteholders on the Common Collateral will
not be released, except to the extent that the Common Collateral, or any
portion thereof, was disposed of in order to repay the Lender Claims, and
thereafter, the Trustee (acting at the direction of the Noteholders) will have
the right to exercise remedies with respect to the Common Collateral (but in
such event, the Liens granted to the Trustee or the Noteholders on the Common
Collateral shall be released when such event of default (and all other events
of default under the Indenture or any other Noteholder Document) cease to
exist), and (B) in the case of clause (a)(ii), if the Lender Claims (or any
portion thereof) are thereafter secured by assets that would constitute Common
Collateral, the Noteholder Claims shall then be secured by a second priority
Lien on such Common Collateral, to the same extent provided pursuant to the
Noteholder Collateral Documents.

     (b) The Trustee, for itself and on behalf of the Noteholders, hereby
irrevocably constitutes and appoints the Administrative Agent and any officer
or agent of the Administrative 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 Noteholder or in the Administrative
Agent's own name, from time to time in the Administrative 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 releases, documents and
instruments which may be necessary or desirable to accomplish the purposes of
this Section 5.1, including any financing statements, mortgage releases,
intellectual property releases, endorsements or other instruments or transfer
or release.

     SECTION 5.2 Insurance. Unless and until the Discharge of Lender Claims has
occurred, the Administrative Agent and the other Secured Parties shall have the
sole and exclusive right, subject to the rights of the Obligors under the Loan
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 Lender Claims has occurred (and whether or
not the Revolving Loan Commitment Termination Date has occurred), all proceeds
of any such policy and any such award if in respect to the Common Collateral
shall be paid to the Administrative Agent for the benefit of the Secured
Parties to the extent required under the Credit Agreement and any Future
First-Lien Credit 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.

     SECTION 5.3 Amendments to Noteholder Collateral Documents.

     (a) Unless and until the Discharge of Lender Claims has occurred, without
the prior written consent of the Administrative Agent and the Required Lenders,
no Noteholder Document


                                       9



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 Document, would be inconsistent with any of the terms of this
Agreement or the Loan Documents. The Trustee agrees that each Noteholder
Collateral Document to which the Trustee is a party shall include the following
language:

          "Notwithstanding anything herein to the contrary, the lien and
     security interest granted to the Trustee pursuant to this Agreement and
     the exercise of any right or remedy by the Trustee hereunder are subject
     to the provisions of the Intercreditor Agreement, dated as of April 23,
     2004 (as amended, supplemented, amended and restated or otherwise modified
     from time to time, the "Intercreditor Agreement") among Credit Suisse
     First Boston, acting through its Cayman Islands Branch, as Administrative
     Agent, Law Debenture Trust Company of New York, as Trustee, Mueller Group,
     Inc., and the other Obligors party thereto, including any grantor of a
     security interest pursuant to this Agreement, named therein. In the event
     of any conflict between the terms of the Intercreditor Agreement and this
     Agreement, the terms of the Intercreditor Agreement shall govern."

     (b) In the event the Administrative Agent enters into any amendment,
waiver or consent in respect of any of the Obligor Pledge Agreements for the
purpose of adding to, or deleting from, or waiving or consenting to any
departures from any provisions of, any Obligor Pledge Agreement or changing in
any manner the rights of the Administrative Agent, the Secured Parties or the
Obligors 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 or any Obligor; provided that (A) 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, (B) any such amendment,
waiver or consent that materially and adversely affects the rights of the
Trustee and the Noteholders (and not the holders of the Lender Liens in a like
or similar manner) shall not apply to the Noteholder Collateral Documents
without the consent of the Trustee (acting at the direction of the holders of a
majority of the aggregate principal amount of the applicable Noteholder Claims)
and (C) notice of such amendment, waiver or consent shall have been given to
the Trustee; provided, further, that (x) nothing contained in this clause (b)
shall impair the rights of the Administrative Agent and the holders of Lender
Claims, or the obligations and agreements of the Trustee and Noteholders, under
Sections 3 and 5.1 hereof and (y) the Obligor Pledge Agreements and Noteholder
Security Documents may, without the consent of the Trustee or the Noteholders,
be amended or modified pursuant to this Section 5.3(b) to secure additional
extensions of credit and add additional secured creditors as long as such
amendments or modifications do not violate the express provisions of the
Indenture or any other Noteholder Document.

     SECTION 5.4 Rights As Unsecured Creditors. Notwithstanding anything to the
contrary in this Agreement, the Trustee and the Noteholders may exercise rights
and remedies as an unsecured creditor against the Obligors in accordance with
the terms of the Noteholder


                                      10



Documents and applicable law. Nothing in this Agreement shall prohibit the
receipt by the Trustee or any Noteholders of the required payments of interest
and principal on the Notes so long as such receipt is not the direct or
indirect result of the exercise by the Trustee or any Noteholder of rights and
remedies as a secured creditor or enforcement of any Lien held by any of them
in contravention of this Agreement. In the event that 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 subject to the terms of this Agreement for all purposes
(including in relation to the Lender Liens and the Lender Claims) as the other
Liens securing the Noteholder Claims (created pursuant to the Noteholder
Collateral Documents) subject to this Agreement. Nothing in this Agreement
modifies any rights or remedies the Secured Parties may have with respect to
the Lender Collateral.

     SECTION 5.5 Bailee for Perfection.

     (a) Solely for the purpose of perfecting the security interest granted in
such Pledged Collateral pursuant to the Noteholder Collateral Documents, and
subject to the terms and conditions of this Section 5.5, the Administrative
Agent agrees: (i) to hold the Pledged 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, (ii) with
respect to any securities accounts included in the Collateral, it has "control"
within the meaning of Section 8-106(d)(3) of such securities accounts on behalf
of the Trustee and any assignee and (iii) with respect to any deposit accounts
included in the Collateral, it is acting as agent for the Trustee and any
assignee.

     (b) The rights of the Trustee shall at all times be subject to the terms
of this Agreement and to the Administrative Agent's rights under the Loan
Documents.

     (c) The Administrative Agent shall have no obligation whatsoever to the
Trustee or any Noteholder to assure that the Pledged Collateral is genuine or
owned by any Obligor 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
Administrative Agent under this Section 5.5 shall be limited solely to holding
the Pledged Collateral as bailee or agent for the Trustee for purposes of
perfecting the Lien held by the Trustee.

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

     (e) Upon the Discharge of Lender Claims, the Administrative Agent shall
deliver to the Trustee, at the sole cost and expense of the Company, the
Pledged Collateral in its possession together with any necessary endorsements
(or otherwise allow the Trustee to obtain control of such Pledged Collateral)
to the extent required by the Noteholder Documents or as a court of competent
jurisdiction may otherwise direct.

     SECTION 5.6 When Discharge of Lender Claims Deemed to Not Have Occurred.
If at any time after the Discharge of Lender Claims has occurred the Company
designates any Future First-Lien Credit Facility to be the "Credit Agreement"
hereunder, then such Discharge of


                                      11



Lender Claims shall automatically be deemed not to have occurred for all
purposes of this Agreement (other than with respect to any actions taken prior
to the date of such designation as a result of the occurrence of such first
Discharge of Lender Claims), and such Future First-Lien Credit Facility shall
automatically be treated as the Credit Agreement for all purposes of this
Agreement, including without limitation for purposes of the Lien priorities and
rights in respect of Collateral set forth herein; provided, however, that no
designation of any Future First-Lien Credit Facility shall apply retroactively
and the Trustee and the Noteholders shall be entitled to retain any collateral
proceeds or other payments or property received by them prior to the
designation of such Future First-Lien Credit Facility. Upon receipt of notice
of such designation (including the identity of the new Administrative Agent),
the Trustee shall promptly deliver to the Administrative Agent the Pledged
Collateral together with any necessary endorsements (or otherwise allow such
Administrative Agent to obtain control of such Pledged Collateral). If the
Obligations under a Future First-Lien Credit Facility are secured by assets of
the Obligors of the type constituting Common Collateral that do not also secure
the Noteholder Claims, then the Notes shall be secured at such time by a second
priority Lien on such assets to the same extent provided in the Noteholder
Collateral Documents.

     SECTION 6. Insolvency or Liquidation Proceedings.

     SECTION 6.1 Sale Issues. If any Obligor shall be subject to any Insolvency
or Liquidation Proceeding and the Administrative Agent shall desire to permit
the use of cash collateral or to permit the Company 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 Lender Liens are junior in priority or pari
passu with such DIP Financing, will maintain the priority of its Liens in the
Common Collateral as junior in priority to such Lender Liens on the same basis
as the other Liens securing the Noteholder Claims are second in priority to
Lender Claims under this Agreement.

     SECTION 6.2 Relief from the Automatic Stay. While any amounts are
outstanding under the Loan Documents or any commitment under any DIP Financing
provided by any Secured Party is in effect, 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
Administrative Agent and the Required Lenders.

     SECTION 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 Administrative Agent or the other
Secured Parties for adequate protection or (b) any objection by the
Administrative Agent or the other Secured Parties to any motion, relief, action
or proceeding which objection is based on the Administrative Agent or the other
Secured Parties claiming a lack of adequate protection. Notwithstanding the
foregoing contained in this Section 6.3, in any Insolvency or Liquidation
Proceeding, (i) if the Secured Parties (or any subset thereof) are granted
adequate protection in the form of additional collateral in connection with any
DIP Financing or use of their 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


                                      12



request adequate protection in the form of a replacement Lien on such
additional collateral, which Lien is junior in priority to the Lender Liens and
such DIP Financing (and all Obligations relating thereto) on the same basis as
the other Liens securing the Noteholder Claims are junior in priority to the
Lender Claims and Lenders Liens 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 Secured Parties shall also be granted a Lien on such additional
collateral as security for the Lender Claims and any such DIP Financing and
that any Lien on such additional collateral securing the Noteholder Claims
shall be junior in priority to the Liens on such collateral securing the Lender
Claims and any such DIP Financing (and all Obligations relating thereto) and
any other Liens granted to the Secured Parties as adequate protection on the
same basis as the other Liens securing the Noteholder Claims are junior in
priority to such Lender Claims under this Agreement.

     SECTION 6.4 No Waiver; Voting Rights. Nothing contained herein shall
prohibit or in any way limit the Administrative Agent or any other Secured
Party from objecting in any Insolvency or Liquidation Proceeding or otherwise
to any action taken by the Trustee or any of the Noteholders, including 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. In any Insolvency or Liquidation
Proceeding, neither the Trustee nor any Noteholder shall vote any Noteholder
Claim for any plan of reorganization of any Obligor unless (i) such plan
provides for the payment in full in cash of all Lender Claims on the effective
date of such plan of reorganization, (ii) such plan provides for treatment of
the Lender Claims in a manner that would result in such Lender Claims having
relative lien (or, if the obligations, property or assets to be distributed in
respect of the Lender Claims under such plan are unsecured, other) priority
over the Noteholder Claims to at least the same extent as if such obligations,
property or assets were secured by Liens and subject to Section 6.6, whether or
not such obligations, property or assets are, in fact, secured by any such
Liens, and (iii) the plan otherwise provides treatment of the Lender Claims in
a manner approved by the Administrative Agent and the Required Lenders.

     SECTION 6.5 Preference Issues. If any Secured Party is required in any
Insolvency or Liquidation Proceeding or otherwise to turn over or otherwise pay
to the estate of any Obligor any amount as a preference (a "Recovery"), then
the Lender Claims shall be reinstated to the extent of such Recovery and the
Secured Parties shall be entitled to a Discharge of Lender Claims 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.

     SECTION 6.6 Reorganization Securities. If, in any Liquidation or
Insolvency 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 Lender Claims and on account of Noteholder Claims, then, to the
extent the debt obligations distributed on account of the Lender Claims and on
account of the Noteholder Claims are secured by Liens upon the same property,
the provisions of this


                                      13



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.

     SECTION 6.7 Expense Claims. Neither the Trustee nor any Noteholder will
assert or enforce, at any time prior to the Discharge of Lender Claims, any
claim under ss.506(c) of the Bankruptcy Code senior to or on a parity with the
Lender Liens for costs or expenses of preserving or disposing of any Common
Collateral.

     SECTION 6.8 Post-Petition Claims. (a) Neither the Trustee nor any
Noteholder shall oppose or seek to challenge any claim by the Administrative
Agent or any other Secured Party for allowance in any Insolvency or Liquidation
Proceeding of Lender Claims consisting of post-petition interest, fees or
expenses to the extent of the value of the Lender Lien, without regard to the
existence of the Lien of the Trustee on behalf of the Noteholders on the Common
Collateral.

     (b) Neither the Administrative Agent nor any other Secured Party shall
oppose or seek to challenge any claim by the Trustee or any Noteholder for
allowance in any Insolvency or Liquidation Proceeding of Noteholder Claims
consisting of post-petition interest, fees or expenses to the extent of the
value of the Lien of the Trustee on behalf of the Noteholders on the Common
Collateral (after taking into account the Lender Liens).

     SECTION 7. Reliance; Waivers; etc.

     SECTION 7.1 Reliance. The consent by the Secured Parties to the execution
and delivery of the Noteholder Documents and the grant to the Trustee, on
behalf of the Noteholders, of a Lien on the Common Collateral and all loans and
other extensions of credit continued, made or deemed made on and after the date
hereof by the Secured Parties to the Company shall be deemed to have been given
and continued or made in reliance upon this Agreement. The Trustee, on behalf
of itself and the Noteholders, acknowledges that it and the Noteholders have,
independently and without reliance on the Administrative Agent or any other
Secured Party, and based on documents and information deemed by them
appropriate, made their own credit analysis and decision to enter into the
Indenture or any other applicable Noteholder Document, this Agreement and the
transactions contemplated hereby and thereby and they will continue to make
their own credit decisions in taking or not taking any action under the
Indenture, any such other Noteholder Document or this Agreement.

     SECTION 7.2 No Warranties or Liability. The Trustee, on behalf of itself
and Noteholders, acknowledges and agrees that each of the Administrative Agent
and the other Secured Parties 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 Loan Documents.
The Secured Parties will be entitled to manage and supervise their respective
loans and extensions of credit to the Company in accordance with law and as
they may otherwise, in their sole discretion, deem appropriate, and the Secured
Parties may manage their loans and extensions of credit without regard to any
rights or interests that the Trustee or any of the Noteholders have in the
Common Collateral or otherwise, except as otherwise provided in this Agreement.
Neither the Administrative Agent nor any Secured Party shall have any duty to
the Trustee or any of the Noteholders 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


                                      14



agreements with any the Company (including the Noteholder Documents),
regardless of any knowledge thereof which they may have or be charged with.

     SECTION 7.3 No Waiver of Lien Priorities.

     (a) To the fullest extent permitted under applicable law, no right of the
Secured Parties, the Administrative 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 any Obligor or by any act
or failure to act by any Secured Party, or by any noncompliance by any Person
with the terms, provisions and covenants of this Agreement, any of the Loan
Documents or any of the Noteholder Documents, regardless of any knowledge
thereof which the Administrative Agent or the other Secured Parties, 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 Obligors under the Loan Documents), the
Secured Parties and any of them, may, to the fullest extent permitted under
applicable law, 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 Noteholder 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 Trustee or any Noteholder is
affected, impaired or extinguished thereby) do any one or more of the
following:

          (i) make loans and advances to any Obligor or issue, guaranty or
     obtain letters of credit for the account of any Obligor or otherwise
     extend credit to any Obligor, in any amount (subject to the limits set
     forth in the Indenture or any other Noteholder Document) and on any terms,
     whether pursuant to a commitment or as a discretionary advance and whether
     or not any default or event of default or failure of condition is then
     continuing;

          (ii) change the manner, place or terms of payment or change or extend
     the time of payment of, or renew, exchange, amend, increase (subject to
     the limits set forth in the Indenture or any other Noteholder Document) or
     alter, the terms of any of the Lender Claims or any Lien on any Lender
     Collateral or guaranty thereof or any liability of the Obligors, or any
     liability incurred directly or indirectly in respect thereof (including
     any increase in (subject to the limits set forth in the Indenture or any
     other Noteholder Document) or extension of the Lender Claims, without any
     restriction as to the amount, tenor or terms of any such increase (subject
     to the limits set forth in the Indenture or any other Noteholder Document)
     or extension) or otherwise amend, renew, exchange, extend, modify or
     supplement in any manner any Liens held by the Secured Parties, the Lender
     Claims or any of the Loan Documents;

          (iii) subject, in the case of Pledged Collateral, to Section 5.5,
     sell, exchange, release, surrender, realize upon, enforce or otherwise

     any Obligor or any security therefor or any liability incurred directly or
     indirectly in respect thereof and apply any sums by whomsoever paid and

     manner or order;

          (v) exercise or delay in or refrain from exercising any right or
     remedy against any Obligor or any security or any other Person, elect any
     remedy and otherwise deal freely with the Obligors and the Lender
     Collateral and any security or any liability of any Obligor to the Secured
     Parties or any liability incurred directly or indirectly in respect
     thereof;

          (vi) release or discharge any Lender Claims or any guaranty thereof
     or any agreement or obligation of any Obligor or any other person or
     entity with respect thereto;

          (vii) take or fail to take any Lender Lien or any other collateral
     security for any Lender Claims or take or fail to take any action which
     may be necessary or appropriate to ensure that any Lender Lien or any
     other Lien upon any property is duly enforceable or perfected or entitled
     to priority as against any other Lien or to ensure that any proceeds of
     any property subject to any Lien are applied to the payment of any Lender
     Claim or any other obligation secured thereby; or

          (viii) release, discharge or permit the lapse of any or all Lender
     Liens or any other Liens upon any property at any time securing any Lender
     Claims;

     (c) The Trustee, on behalf of itself and the Noteholders, also agrees, to
the fullest extent permitted under applicable law, that no Secured Party shall
have any liability to the Trustee or any Noteholder, and the Trustee, on behalf
of itself and the Noteholders, to the fullest extent permitted under applicable
law, hereby waives any claim against any Secured Party, arising out of any and
all actions which such Secured Parties may take or permit or omit to take with
respect to: (i) the Loan Documents, (ii) the collection of the Lender Claims or
(iii) the foreclosure upon, or sale, liquidation or other disposition of, the
Lender Collateral. The Trustee, on behalf of itself and the Noteholders, agrees
that neither the Administrative Agent (except as expressly set forth in Section
5.5) nor any other Secured Party shall have any duty to them, express or
implied, fiduciary or otherwise, in respect of the maintenance or preservation
of the Lender Collateral, the Lender Claims 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.

     SECTION 7.4 Obligations Unconditional. All rights, interests, agreements
and obligations of the Administrative Agent and the other Secured Parties and
the Trustee and the Noteholders, respectively, hereunder shall remain in full
force and effect irrespective of:

     (a) any lack of validity or enforceability of any Loan Documents or any
Noteholder Documents or any setting aside or avoidance of any Lender Lien;


                                      16

writing or by course of conduct or otherwise, of all or any of the Lender
Claims or Noteholder Claims or any guarantee thereof;

     (d) the commencement of any Insolvency or Liquidation Proceeding in
respect of any Obligor; or

     (e) any other circumstances which otherwise might constitute a defense
available to, or a discharge of, any Obligor in respect of the Lender Claims,
or of the Trustee, any Noteholder, the Administrative Agent or any other
Secured Party in respect of this Agreement.

guarantors of the Noteholder Claims or the Lender Claims and (b) all other

known to it or them regarding such condition or any such circumstances or
otherwise. In the event the Administrative Agent or any other Secured Party, in
its sole discretion, undertakes at any time or from time to time to provide any
