     Borrowers' obligations under the Documents or in respect of the Cash
     Management Obligations.

3.2  Neither the obligations of the Guarantor herein contained nor the rights,

     or otherwise affected by:

     (i)       the winding-up, dissolution, administration or reorganisation of
               any of the Borrowers or any change in their status, function,
               control or ownership;

     (ii)      any of the obligations of any of the Borrowers under the
               Documents or in respect of the Cash Management Obligations or
               under any other security relating to the Documents being or

     (iii)     time or other indulgence being granted or agreed to be granted to
               any of the Borrowers in respect of their obligations under the
               Documents or in respect of the Cash Management Obligations or
               under any other security;

     (iv)      any amendment to, or any variation, waiver or release of any
               obligation of any of the Borrowers under the Documents or in

               security;

     (v)       any failure to take, or fully to take, any security contemplated
               by the Documents or in respect of the Cash Management Obligations
               or otherwise agreed to be taken in respect of any of the
               Borrowers' obligations under the Documents or in respect of the
               Cash Management Obligations;

     (vi)      any failure to realise or fully to realise the value of, or any
               release, discharge, exchange or substitution of, any security
               taken in respect of any of the Borrowers' obligations under the
               Documents or in respect of the Cash Management Obligations; or

     (vii)     any other act, event or omission which, but for this Clause 3.2,
               might operate to discharge, impair or otherwise affect any of the
               obligations of the Guarantor herein contained or any of the
               rights, powers or remedies conferred upon the
<PAGE>

               Administrative Agent or any of the Obligees by the Documents
               or in respect of the Cash Management Obligations or by law.

3.3  Any settlement or discharge given by the Administrative Agent and/or any of
     the Obligees to the Guarantor in respect of the Guarantor's obligations
     hereunder or any other agreement reached between the Administrative Agent
     and/or any of the Obligees and the Guarantor in relation thereto shall be,
     and be deemed always to have been, void if any act on the faith of which
     the Administrative Agent and/or any of the Obligees gave the Guarantor that
     settlement or discharge or entered into that agreement is subsequently
     avoided by or in pursuance of any provision of law.

3.4  The Administrative Agent and/or any of the Obligees shall not be obliged

               of any Borrower; or

     (iv)      to enforce or seek to enforce any security taken in respect of
               any of the obligations of any of the Borrowers under the
               Documents or in respect of the Cash Management Obligations.

3.5  The Guarantor agrees that, so long as any amounts are or may be owed by any
     Borrower under the Documents or in respect of the Cash Management
     Obligations or any Borrower is under any actual or contingent obligations
     under the Documents or in respect of the Cash Management Obligations, the
     Guarantor shall not exercise any rights which the Guarantor may at any time
     have by reason of performance by it of its obligations hereunder:

     (i)       to be indemnified by any of the Borrowers;

     (ii)      to claim any contribution from any other guarantor of any of the
               Borrowers' obligations under the Documents or in respect of the
               Cash Management Obligations; and/or

     (iii)     to take the benefit (in whole or in part and whether by way of
               subrogation or otherwise) of any rights of the Administrative
               Agent and/or the Obligees under the Documents or in respect of
               the Cash Management Obligations or of any other security taken
               pursuant to, or in connection with, the Documents or in respect
               of the Cash Management Obligations by the Administrative Agent
               and/or the Obligees.

4.   REPRESENTATIONS AND WARRANTIES

     The Guarantor represents and warrants to each of the Obligees that the
     representations and warranties set forth in Article VIII of the Credit
     Agreement as they relate to the Guarantor or to the Documents to which the
     Guarantor is a party or in respect of the
<PAGE>

     Cash Management Obligations, each of which is hereby incorporated herein by
     reference, are true and correct, and the Administrative Agent and each
     Obligee shall be entitled to rely on each of them as if they were fully set
     forth herein provided that each reference in each such representation and
     warranty to the Company's knowledge shall, for the purposes of this Clause
     4, be deemed to be a reference to the Guarantor's knowledge.

5.   PAYMENTS

     The provisions of the Credit Agreement relating to the payments to be made
     thereunder (including, without limitation, those regulating what is to
     happen if the Borrowers are required by law to make a deduction or
     withholding from any such payment) shall apply mutatis mutandis to payments
     to be made hereunder.

6.   CURRENCY OF ACCOUNT

     Moneys received or recovered by the Administrative Agent from the Guarantor
     in a currency other than that in which the said sums are due and payable
     under or pursuant to the Documents or in respect of the Cash Management
     Obligations or under Clause 2 hereof shall be converted into the latter
     currency at the spot rate for purchasing Dollars with such moneys as set
     forth in The Wall Street Journal on the business day prior to the date on
     which such calculation is made.

7.   CONTINUING SECURITY

     The obligations of the Guarantor herein contained shall constitute and be
     continuing obligations notwithstanding any settlement of account or other
     matter or thing whatsoever, and in particular but without limitation, shall
     not be considered satisfied by any intermediate payment or satisfaction of
     all or any of the obligations of any of the Borrowers under the Documents
     or in respect of the Cash Management Obligations and shall continue in full
     force and effect until final payment in full of all amounts owing by the
     Borrowers thereunder and total satisfaction of all the Borrowers' actual
     and contingent obligations thereunder.

8.   SET-OFF

     Upon the occurrence and during the continuation of any Event of Default,
     the Guarantor hereby irrevocably authorises each Obligee at any time and
     from time to time without notice to the Guarantor, any such notice being
     expressly waived by the Guarantor, to set-off and appropriate and apply any
     and all deposits (general or special, time or demand, provisional or
     final), in any currency, and any other credits, indebtedness or claims, in
     any currency, in each case whether direct or indirect, absolute or
     contingent, matured or unmatured, at any time held or owing by such Obligee
     to or for the credit or the account of the Guarantor, or any part thereof
     in such amounts as such Obligee may elect, against and on account of the
     obligations and liabilities of the Guarantor to such Obligee hereunder
     which are then due and payable and claims of every nature and description
     of such Obligee against the Guarantor, in any currency, whether arising
     hereunder, under any of the Documents or in respect of the Cash Management
     Obligations or otherwise in connection therewith, as such Obligee may
     elect, whether or not the Administrative Agent or any Obligee has made any
     demand for payment and although such obligations,
<PAGE>

     liabilities and claims may be contingent or unmatured. The Administrative
     Agent and each Obligee shall notify the Guarantor promptly of any such set-
     off and the application made by the Administrative Agent or such Obligee
     provided that the failure to give such notice shall not affect the validity
     of such set-off and application. The rights of the Administrative Agent and
     each Obligee under this Clause are in addition to other rights and remedies
     (including, without limitation, other rights of set-off) which the
     Administrative Agent or such Obligee may have.

Trust Agreement and the Trust Security Documents and accomplish the purposes
hereof and thereof and, without limiting the generality of the foregoing, each
Obligor hereby acknowledges that the Trustee shall have all powers and remedies
set forth in the Trust Security Documents, subject to Section 2.1.
Notwithstanding the foregoing, so long as no Notice of Acceleration is in
effect, the Trustee shall take such actions and exercise such remedies as are
permitted by the Trust Security Documents in accordance with the instructions of
the Administrative Agent delivered to the Trustee. In the event that, pursuant
to the terms of the relevant Trust Security Document or Secured Instrument, the
Administrative Agent shall only be entitled to direct the Trustee after the
occurrence of an Event of Default, the Administrative Agent shall certify in
such direction that an Event of Default has occurred and is continuing.

          2.3 Right to Initiate Judicial Proceedings.  If a Notice of
          ------------------------------------------
Acceleration is in effect, the Trustee, subject to the provisions of Section

maintain such suits and proceedings as it may deem appropriate to protect and
enforce the rights vested in it by this Trust Agreement and each Trust Security
Document and (ii) may, either after entry, or without entry, proceed by suit or
suits at law or in equity to enforce such rights and to foreclose upon the
Collateral and to sell all or, from time to time, any of the Collateral under
the judgment or decree of a court of competent jurisdiction.

          2.4 Right to Appoint a Receiver.  If a Notice of Acceleration is in
          -------------------------------
effect, upon the filing of a bill in equity or other commencement of judicial
proceedings to enforce the rights of the Trustee under this Trust Agreement or
any Trust Security Document, the Trustee shall, to the extent permitted by law,
with notice to the Company but without notice to any party claiming through the
Obligors, without regard to the solvency or insolvency at the time of any Person
then liable for the payment of any of the Secured Obligations, without regard to
the then value of the Trust Estate, and without requiring any bond from any
complainant in such proceedings, be entitled as a matter of right to the
appointment of a receiver or receivers of the Trust Estate, or any part thereof,
and of the rents, issues, tolls, profits, royalties, revenues and other income
thereof, pending such proceedings, with such powers as the court making such
appointment shall confer, and to the entry of an order directing that the rents,
issues, tolls, profits, royalties, revenues and other income of the property
constituting the whole or any part of the Trust Estate be segregated,
sequestered and impounded for the benefit of the Trustee and the Secured
Parties, and each Obligor irrevocably consents to the appointments of such
receiver or receivers and to the entry of such order; provided that,
                                                      --------
notwithstanding the appointment of any receiver, the Trustee shall be entitled
to retain possession and control of all cash and Cash Equivalents held by or
deposited with it pursuant to this Trust Agreement or any Trust Security
Document.

          (b) While a Notice of Acceleration is in effect, the Required Secured
Parties shall have the right, by one or more instruments in writing executed and
delivered to the Trustee, to direct the time, method and place of conducting any
proceeding for any right or remedy available to the Trustee, or of exercising
any trust or power conferred on the Trustee, or for the appointment of a
receiver, or to direct the taking or the refraining from taking of any action
authorized by this Trust Agreement or any Trust Security Document; provided that
                                                                   --------
(i) such direction shall not conflict with any provision of law or of this Trust
Agreement or of any Trust Security Document and (ii) the Trustee shall be
adequately secured and indemnified as provided in Section 5.4(d). Nothing in
this Section 2.5(b) shall impair the right of the Trustee in its discretion to
take any action which it deems proper and which is not inconsistent with such
direction by the Required Secured Parties. In the absence of such direction, the
Trustee shall have no duty to take or refrain from taking any action unless
explicitly required herein.

          (c) If, within 45 days after the Trustee receives a Notice of
Acceleration which has not been cancelled, the Trustee shall not have received
written directions from the Required Secured Parties pursuant to Section 2.5(b)
for the exercise of rights or remedies by the Trustee, the Trustee shall, until
the Trustee receives written directions from the Required Secured Parties,
follow written directions from the Administrative Agent.

          2.6 Remedies Not Exclusive.  (a) No remedy conferred upon or reserved
          --------------------------
to the Trustee herein or in the Trust Security Documents is intended to be
exclusive of any other remedy or remedies, but every such remedy shall be
cumulative and shall be in addition to every other remedy conferred herein or in
any Trust Security Document or now or hereafter existing at law or in equity or
by statute.

          (b) No delay or omission by the Trustee to exercise any right, remedy
or power hereunder or under any Trust Security Document shall impair any such
right, remedy or power or shall be construed to be a waiver thereof, and every
right, power and remedy given by this Trust Agreement or any Trust Security
Document to the Trustee may be exercised from time to time and as often as may
be deemed expedient by the Trustee.

          (c) If the Trustee shall have proceeded to enforce any right, remedy
or power under this Trust Agreement or any Trust Security Document and the
proceeding for the enforcement thereof shall have been discontinued or abandoned
for any reason or shall have been determined adversely to the Trustee, then the
Obligors, the Trustee and the Secured Parties shall, subject to any
determination in such proceeding, severally and respectively be restored to
their former positions and rights hereunder or thereunder with respect to the
Trust Estate and in all other respects, and thereafter all rights, remedies and
powers of the Trustee shall continue as though no such proceeding had been
taken.

          (d) All rights of action and of asserting claims upon or under this
Trust Agreement and the Trust Security Documents may be enforced by the Trustee
without the possession of any Secured Instrument or instrument evidencing any
Secured Obligation or the production thereof at any trial or other proceeding
relative thereto, and any suit or proceeding instituted by the Trustee shall be,
subject to Sections 5.5(c) and 5.10(b)(ii), brought in its name as Trustee and
any recovery of judgment shall be held as part of the Trust Estate.

          2.7  Waiver and Estoppel. (a) Each Obligor agrees, to the extent it
          ------------------------
may lawfully do so, that it will not at any time in any manner whatsoever claim,
or take the benefit or advantage of, any appraisement, valuation, stay,
extension, moratorium, turnover or redemption law, or any law permitting it to
direct the order in which the Collateral shall be sold, now or at any time
hereafter in force, which may delay, prevent or otherwise affect the performance
or enforcement of this Trust Agreement or any Trust Security Document and hereby
waives all benefit or advantage of all such laws and covenants that it will not
hinder, delay or impede the execution of any power granted to the Trustee in
this Trust Agreement or any Trust Security Document but will suffer and permit
the execution of every such power as though no such law were in force; provided
                                                                       --------
that nothing contained in this Section 2.7(a) shall be construed as a waiver of
any rights of the Obligors under any applicable federal bankruptcy law or state
insolvency law.

          (b)  Each Obligor, to the extent it may lawfully do so, on behalf of
itself and all who may claim through or under it, including without limitation
any and all subsequent creditors, vendees, assignees and lienors, waives and
releases all rights to demand or to have any marshalling of the Collateral upon
any sale, whether made under any power of sale granted herein or in any Trust
Security Document or pursuant to judicial proceedings or upon any foreclosure or
any enforcement of this Trust Agreement or any Trust Security Document and
consents and agrees that all the Collateral may at any such sale be offered and
sold as an entirety.

          (c)  Each Obligor waives, to the extent permitted by applicable law,
presentment, demand, protest and any notice of any kind (except notices
explicitly required hereunder or under any Trust Security Document) in
connection with this Trust Agreement and the Trust Security Documents and any
action taken by the Trustee with respect to the Collateral.

          2.8  Limitation on Trustee's Duty in Respect of Collateral. Beyond its
          ----------------------------------------------------------
duties as to the custody thereof expressly provided herein or in any Trust
Security Document and to account to the Secured Parties and the Obligors for
moneys and other property received by it hereunder or under any Trust Security
Document, the Trustee shall not have any duty to the Obligors or to the Secured
Parties as to any Collateral in its possession or control or in the possession
or control of any of its agents or nominees, or any income thereon or as to the
preservation of rights against prior parties or any other rights pertaining
thereto.

          2.9  Limitation by Law. All rights, remedies and powers provided in
          ----------------------
this Trust Agreement or any Trust Security Document may be exercised only to the
extent that the exercise thereof does not violate any applicable provision of
law, and all the provisions hereof are intended to be subject to all applicable
mandatory provisions of law which may be controlling and to be limited to the
extent necessary so that they will not render this Trust Agreement invalid,
unenforceable in whole or in part or not entitled to be recorded, registered or
filed under the provisions of any applicable law.

          2.10 Rights of Secured Parties under Secured Instruments.
          --------------------------------------------------------

maturity thereof, by acceleration or otherwise) as expressed in the related
Secured Instrument or other instrument evidencing or agreement governing a
Secured Obligation or to institute suit for the enforcement of such payment on
or after such due date, and

                                     -13-
<PAGE>

the obligation of the Obligors to pay such Secured Obligation when due, shall
not be impaired or affected without the consent of such Secured Party given in
the manner prescribed by the Secured Instrument under which such Secured
Obligation is outstanding.

                                  SECTION 3.

                       COLLATERAL ACCOUNT; DISTRIBUTIONS

          3.1  The Collateral Account. On the Trust Effective Date there shall
          ---------------------------
be established and, at all times thereafter until the trusts created by this
Trust Agreement shall have terminated, there shall be maintained with the
Trustee at the office of the Trustee's corporate trust division, an account
which shall be entitled the "Federal-Mogul Collateral Account" (the "Collateral
                                                                     ----------
Account") and which shall be comprised of two sub-accounts entitled the
-------
"Federal-Mogul Restricted Collateral Sub-Account" (the "Restricted Collateral
                                                        ---------------------
Sub-Account") and the "Federal-Mogul Other Collateral Sub-Account" (the "Other
-----------                                                              -----
Collateral Sub-Account"), respectively. All moneys which are required by this
----------------------
Trust Agreement or any Trust Security Document to be delivered to the Trustee
while a Notice of Acceleration is in effect or which are received by the Trustee
or any agent or nominee of the Trustee in respect of the Collateral, whether in
connection with the exercise of the remedies provided in this Trust Agreement or
any Trust Security Document or otherwise, while a Notice of Acceleration is in
effect shall be deposited (i) in the Restricted Collateral Sub-Account if such
moneys are in respect of Restricted Collateral or (ii) in the Other Collateral
Sub-Account if such moneys are in respect of Other Collateral and, in each case,
held by the Trustee as part of the Trust Estate and applied in accordance with
the terms of this Trust Agreement. The Trustee shall be entitled to receive a
certification from the Company or the Administrative Agent as to whether moneys
received by the Trustee are in respect of the Restricted Collateral or the Other
Collateral, and in the absence of such certification shall hold such moneys in
the Restricted Collateral Sub-Account. Upon the cancellation of any Notice of
Acceleration pursuant to Section 2.1(c), the Trustee shall (subject to the first
sentence of Section 3.4(a)) cause all funds on deposit in the Collateral Account
to be paid over to the Obligors in accordance with their respective interests.

          3.2  Control of Collateral Account. All right, title and interest in
          ----------------------------------

the Collateral Account shall constitute part of the Trust Estate. The Collateral
Account shall be subject to the exclusive dominion and control of the Trustee.

          3.3  Investment of Funds Deposited in Collateral Account. The Trustee
          --------------------------------------------------------
shall, at the direction of the Administrative Agent, invest and reinvest moneys
on deposit in the Collateral Account at any time in Cash Equivalents. All such
investments and the interest and income received thereon and the net proceeds
realized on the sale or redemption thereof shall be held in the Collateral
Account as part of the Trust Estate. The Trustee shall not be responsible for
any diminution in funds resulting from such investments or any liquidation prior
to maturity. In the absence of such directions, the Trustee shall have no
obligation to invest or reinvest moneys.

          3.4  Application of Moneys. (a) The Trustee shall have the right
          --------------------------
(pursuant to Section 4.8) at any time to apply moneys held by it in the
Restricted Collateral Sub-Account and

                                     -14-
<PAGE>

the Other Collateral Sub-Account to the payment of due and unpaid Trustee Fees
without any requirement that such applications be made ratably from such
accounts.  Furthermore, notwithstanding any other provision of this Trust
Agreement or the Trust Security Documents, when taking actions with respect to
the Collateral, the Trustee shall not be obligated to maximize the realization
by the Secured Parties from the Other Collateral before the Secured Parties
realize benefits from the Restricted Collateral.

          (b)  All remaining moneys held by the Trustee in the Restricted
Collateral Sub-Account or received by the Trustee with respect to the Restricted
Collateral while a Notice of Acceleration is in effect shall, to the extent
available for distribution (it being understood that the Trustee may liquidate
investments prior to maturity in order to make a distribution pursuant to this
Section 3.4), be distributed (subject to the provisions of Sections 3.5 and 3.6)
by the Trustee on each Distribution Date in the following order of priority:

          First: to the Trustee for any unpaid Trustee Fees and then to any

     Bankruptcy Code, an amount equal to the amount thereof so advanced or paid
     by such Secured Party and for which such Secured Party has not been
     reimbursed prior to such Distribution Date, and, if such moneys shall be
     insufficient to pay such amounts in full, then ratably (without priority of
     any one over any other) to such Secured Parties in proportion to the
     amounts of such Trustee Fees advanced by the respective Secured Parties and
     remaining unpaid on such Distribution Date;

          Second: to any Secured Party which has theretofore advanced or paid
          ------
     any Trustee Fees other than such administrative expenses, an amount equal

     full, then ratably (without priority of any one over any other) to such
     Secured Parties in proportion to the amounts of such Trustee Fees advanced

     shall be insufficient to pay such amounts in full, then ratably (without
     priority of any one over any other) to the Secured Parties in proportion to
     the unpaid amounts thereof on such Distribution Date;

          -----
     constitute Other Secured Obligations, including without limitation the
     costs and expenses of the Secured Parties and their representatives which
     are due and payable under the relevant Secured Instruments and which
     constitute Other Secured Obligations as of such Distribution Date (but only
     to the extent such Other Secured Obligations constitute Restricted
     Collateral Secured Obligations), and, if such moneys shall be insufficient
     to pay such amounts in full, then ratably to the Secured Parties in

          (c)  All remaining moneys held by the Trustee in the Other Collateral
Sub-Account or received by the Trustee with respect to the Other Collateral
while a Notice of Acceleration is in effect shall, to the extent available for
distribution (it being understood that the Trustee may liquidate investments
prior to maturity in order to make a distribution pursuant to this Section 3.4),
be distributed (subject to the provisions of Sections 3.5 and 3.6) by the
Trustee on each Distribution Date in the following order of priority:

          First: to the Trustee for any unpaid Trustee Fees and then to any
          -----
     Lender or the Administrative Agent which has theretofore advanced or paid
     any Trustee Fees constituting administrative expenses allowable under
     Section 503(b) of the Bankruptcy Code, an amount equal to the amount
     thereof so advanced or paid by such Lender or the Administrative Agent and
     for which such Lender or the Administrative Agent has not been reimbursed
     prior to such Distribution Date, and, if such moneys shall be insufficient
     to pay such amounts in full, then ratably (without priority of any one over
     any other) to such Lenders and the Administrative Agent in proportion to
     the unpaid amounts thereof on such Distribution Date;

          Second: to any Secured Party which has theretofore advanced or paid

          (d)  The term "unpaid" as used in clauses Third and Fourth of Sections
                                                    -----     ------
3.4(b) and 3.4(c) refers:

          (i)  in the absence of a bankruptcy proceeding with respect to the
     relevant Obligor(s), to all amounts of Surety Bond Obligations or Credit
     Agreement Obligations, as the case may be, outstanding as of a Distribution
     Date (and for the purpose of this provision, the amount of the Credit
     Agreement Obligations then outstanding shall include the undrawn face
     amount of, and any unreimbursed drawings under, any Letter of Credit issued
     under the Credit Agreement, the Hedge Agreement Cap Amount with respect to
     any Specified Hedge Agreement and the aggregate amount of Cash Management
     Obligations then due and owing, and the amount of Surety Bond Obligations
     then outstanding shall include the undrawn face amount of, and any
     unreimbursed drawings under, any Surety Bond), and

          (ii) during the pendency of a bankruptcy proceeding with respect to
     the relevant Obligor(s), to all amounts allowed by the bankruptcy court in
     respect of Surety Bond Obligations or Credit Agreement Obligations, as the
     case may be, as a basis for distribution (including estimated amounts, if
     any, allowed in respect of contingent claims),

to the extent that prior distributions (whether actually distributed or set
aside pursuant to Section 3.5) have not been made in respect thereof.

          (e)  The Trustee shall make all payments and distributions under this
Section 3.4: (i) on account of Credit Agreement Obligations to the
Administrative Agent, pursuant to directions of the Administrative Agent, for
re-distribution in accordance with the provisions of the Credit Agreement; and
(ii) on account of Surety Bond Obligations (subject to Section 3.5) to the
relevant Surety Party.

          3.5  Application of Moneys Distributable to Surety Party. If at any
          --------------------------------------------------------
time any moneys collected or received by the Trustee pursuant to this Trust
Agreement are distributable pursuant to Section 3.4 to a Surety Party, and if
such Surety Party shall notify the Trustee in

                                     -17-
<PAGE>

writing that no provision is made under the relevant Surety Bond Documents for
the application by such Surety Party of such moneys (whether because the Secured
Obligations under such Surety Bond Documents have not become due and payable or
otherwise) and that such Surety Bond Documents do not effectively provide for
the receipt and the holding by such Surety Party of such moneys pending the
application thereof, then the Trustee, after receipt of such notification,
shall, at the direction of such Surety Party, invest such amounts in Cash
Equivalents maturing within 90 days after they are acquired by the Trustee or,
in the absence of such direction, hold such moneys uninvested and shall hold all
such amounts so distributable and all such investments and the net proceeds
thereof in trust solely for such Surety Party (in its capacity as trustee) and
for no other purpose until such time as such Surety Party shall request in
writing the delivery thereof by the Trustee for application pursuant to such
Surety Bond Documents.

          3.6  Trustee's Calculations. In making the determinations and
          ---------------------------
allocations required by Section 3.4, the Trustee may conclusively rely upon (a)
information supplied by a Surety Party as to the amount of Surety Bond
Obligations owing to such Surety Party, and (b) information supplied by the
Administrative Agent as to the amounts of unpaid principal and interest and
other amounts outstanding with respect to the Credit Agreement Obligations, and
the Trustee shall have no liability to any of the Secured Parties for actions
taken in reliance on such information, provided that nothing in this sentence
shall prevent any Obligor from contesting any amounts claimed by any Secured
Party in any information so supplied. All distributions made by the Trustee
pursuant to Section 3.4 shall be (subject to any decree of any court of
competent jurisdiction) final (absent manifest error), and the Trustee shall
have no duty to inquire as to the application by the Administrative Agent or a
Surety Party of any amounts distributed to them.

          3.7  Pro Rata Sharing. If, through the operation of any bankruptcy,
          ---------------------
reorganization, insolvency or other laws or otherwise, the Trustee's security
interest hereunder and under the Trust Security Documents is enforced with
respect to some, but not all, of the Secured Obligations then outstanding, the
Trustee shall nonetheless apply the proceeds of the Collateral for the benefit
of the holders of all Secured Obligations in the proportions and subject to the
priorities specified herein. To the extent that the Trustee distributes Proceeds
collected with respect to Secured Obligations held by one holder to or on behalf
of Secured Obligations held by a second holder, the first holder shall be deemed
to have purchased a participation in the Secured Obligations held by the second
holder, or shall be subrogated to the rights of the second holder to receive any
subsequent payments and distributions made with respect to the portion thereof
paid or to be paid by the application of such Proceeds.

                                  SECTION 4.

                            AGREEMENTS WITH TRUSTEE

          4.1  Delivery of Secured Instruments. On the Trust Effective Date, the

the Trust Estate or any part thereof, or as to the title of the Obligors thereto
or as to the security afforded by this Trust Agreement or any Trust Security
Document, or as to the validity, execution (except its execution),
enforceability, legality or sufficiency of this Trust Agreement, the Trust
Security Documents or the Secured Obligations, and the Trustee shall incur no
liability or responsibility in respect of any such matters.

          (b)  The Trustee shall not be required to ascertain or inquire as to
the performance by the Obligors of any of the covenants or agreements contained
herein or in any Trust Security Document or Secured Instrument. Whenever it is
necessary, or in the opinion of the Trustee advisable, for the Trustee to
ascertain the amount of Secured Obligations then held by Secured Parties, the
Trustee may rely on a certificate of the relevant Surety Party, in the case of
Surety Bond Obligations, or a certificate of the Administrative Agent, in the
case of Credit Agreement Obligations, and, if the relevant Surety Party or the
Administrative Agent shall not give such information to the Trustee, it shall
not be entitled to receive distributions hereunder (in which case distributions
to those Persons who have supplied such information to the Trustee shall be
calculated by the Trustee using, for those Persons who have not supplied such
information, the list then most recently delivered by the Company pursuant to
Section 4.2), and the amount so

                                     -21-
<PAGE>

shall be held in trust for such Person until such Person does supply such
information to the Trustee, whereupon on the next Distribution Date the amount
distributable to such Person shall be recalculated using such information and

from contesting any amounts claimed by any Secured Party in any certificate so
supplied.

          (c)  The Trustee shall be under no obligation or duty to take any
action under this Trust Agreement or any Trust Security Document if taking such
action (i) would subject the Trustee to a tax in any jurisdiction where it is
not then subject to a tax or (ii) would require the Trustee to qualify to do
business in any jurisdiction where it is not then so qualified, unless the
Trustee receive security or indemnity satisfactory to it against such tax (or
equivalent liability), or any liability resulting from such qualification, in
each case as results from the taking of such action under this Trust Agreement
or any Trust Security Document.

          (d)  The Trustee shall have the same rights with respect to any
Secured Obligation held by it as any other Secured Party and may exercise such
rights as though it were not the Trustee hereunder, and may accept deposits
from, lend money to, and generally engage in any kind of banking or trust
business with, any of the Obligors as if it were not the Trustee.

          (e)  The Trustee shall not be liable for any action taken or omitted
to be taken in accordance with this Trust Agreement or the Trust Security
Documents except for its own gross negligence or willful misconduct.

          5.3  Delegation of Duties. The Trustee may execute any of the trusts
          -------------------------
or powers hereof and perform any duty hereunder either directly or by or through
agents or attorneys-in-fact. The Trustee shall be entitled to advice of counsel
concerning all matters pertaining to such trusts, powers and duties. The Trustee
shall not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it without gross negligence or willful misconduct.

          5.4  Reliance by Trustee. (a) Whenever in the administration of this
          ------------------------
Trust Agreement or the Trust Security Documents the Trustee shall deem it
necessary or desirable that a factual matter be proved or established in
connection with the Trustee taking, suffering or omitting any action hereunder
or thereunder, such matter (unless other evidence in respect thereof is herein
specifically prescribed) may be deemed to be conclusively proved or established
by a certificate of a Responsible Officer delivered to the Trustee, and such
certificate shall be full warrant to the Trustee for any action taken, suffered
or omitted in reliance thereon, subject, however, to the provisions of Section
5.5.

          (b)  The Trustee may consult with counsel, and any Opinion of Counsel
shall be full and complete authorization and protection in respect of any action
taken or suffered by it hereunder or under any Trust Security Document in
accordance therewith. The Trustee shall have the right at any time to seek
instructions concerning the administration of this Trust Agreement and the Trust
Security Documents from any court of competent jurisdiction.

          (c)  The Trustee may rely, and shall be fully protected in acting,
upon any resolution, statement, certificate, instrument, opinion, report,
notice, request, consent, order, bond or other paper or document which it has no
reason to believe to be other than genuine and to have been signed or presented
by the proper party or parties or, in the case of cables,

                                     -22-
<PAGE>

telecopies and telexes, to have been sent by the proper party or parties. In the
absence of its own gross negligence or willful misconduct, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon any certificates or opinions furnished to the
Trustee and conforming to the requirements of this Trust Agreement.

          (d)  The Trustee shall not be under any obligation to exercise any of
the rights or powers vested in the Trustee by this Trust Agreement and the Trust
Security Documents, at the request or direction of the Required Secured Parties
pursuant to this Trust Agreement or otherwise, unless the Trustee shall have
been provided adequate security and indemnity against the costs, expenses and
liabilities which may be incurred by the Trustee in compliance with such request
or direction, including such reasonable advances as may be requested by the
Trustee.

          (e)  Upon any application or demand by any of the Obligors (except any
such application or demand which is expressly permitted to be made orally) to
the Trustee to take or permit any action under any of the provisions of this
Trust Agreement or any Trust Security Document, the Company shall furnish to the
Trustee a certificate of a Responsible Officer stating that all conditions
precedent, if any, provided for in this Trust Agreement, in any relevant Trust
Security Document or in the Credit Agreement relating to the proposed action
have been complied with, and in the case of any such application or demand as to
which the furnishing of any document is specifically required by any provision
of this Trust Agreement or a Trust Security Document relating to such particular
application or demand, such additional document shall also be furnished.

          (f)  Any Opinion of Counsel may be based, insofar as it relates to
factual matters, upon a certificate of a Responsible Officer or representations
made by a Responsible Officer in a writing filed with the Trustee.

          5.5  Limitations on Duties of Trustee.  (a) Unless a Notice of
          -------------------------------------
Acceleration is in effect, the Trustee shall be obligated to perform such duties
and only such duties as are specifically set forth in this Trust Agreement and
the Trust Security Documents, and no implied covenants or obligations shall be
read into this Trust Agreement or any Trust Security Document against the
Trustee. If and so long as a Notice of Acceleration is in effect, the Trustee
may, subject to the provisions of Section 2.5(b), exercise the rights and powers
vested in the Trustee by this Trust Agreement and the Trust Security Documents,
and shall not be liable with respect to any action taken, or omitted to be
taken, in accordance with the direction of the Required Secured Parties.

          (b)  Except as herein otherwise expressly provided, the Trustee shall
not be under any obligation to take any action which is discretionary with the
Trustee under the provisions hereof or of any Trust Security Document except
upon the written request of the Required Secured Parties. The Trustee shall make
available for inspection and copying by the Administrative Agent and each Surety
Party each certificate or other paper furnished to the Trustee by any of the
Obligors under or in respect of this Trust Agreement or any of the Collateral.

          (c)  No provision of this Trust Agreement or of any Trust Security
Document shall be deemed to impose any duty or obligation on the Trustee to
perform any act or acts or exercise any right, power, duty or obligation
conferred or imposed on it, in any jurisdiction in

                                     -23-
<PAGE>

which it shall be illegal, or in which the Trustee shall be unqualified or
incompetent, to perform any such act or acts or to exercise any such right,
power, duty or obligation or if such performance or exercise would constitute
doing business by the Trustee in such jurisdiction or impose a tax on the
Trustee by reason thereof or to risk its own funds or otherwise incur any
financial liability in the performance of its duties hereunder.

          5.6 Moneys to be Held in Trust.  All moneys received by the Trustee
          ------------------------------
under or pursuant to any provision of this Trust Agreement or any Trust Security
Document (except Trustee Fees) shall be held in trust for the purposes for which
they were paid or are held.

          5.7 Resignation and Removal of the Trustee.  (a)  The Trustee may at
          --------------------------------------------
any time, by giving written notice to the Company, the Administrative Agent and
each Surety Party, resign and be discharged of the responsibilities hereby
created, such resignation to become effective upon (i) the appointment of a
successor Trustee, (ii) the acceptance of such appointment by such successor
Trustee and (iii) the approval of such successor Trustee evidenced by one or
more instruments signed by the Administrative Agent. If no successor Trustee
shall be appointed and shall have accepted such appointment within 90 days after
the Trustee gives the aforesaid notice of resignation, the Trustee, the Company,
the Administrative Agent, any Surety Party or any Secured Party may apply to any
court of competent jurisdiction to appoint a successor Trustee to act until such
time, if any, as a successor Trustee shall have been appointed as provided in
this Section 5.7. Any successor so appointed by such court shall immediately and
without further act be superseded by any successor Trustee appointed by the
Administrative Agent as provided in Section 5.7(b). The Administrative Agent
may, at any time upon giving 30 days' prior written notice thereof to the
Trustee and each Surety Party, remove the Trustee and appoint a successor
Trustee, such removal to be effective upon the acceptance of such appointment by
the successor. The Trustee shall be entitled to Trustee Fees to the extent
incurred or arising, or relating to events occurring, before such resignation or
removal.

          (b) If at any time the Trustee shall resign or be removed or otherwise
become incapable of acting, or if at any time a vacancy shall occur in the
office of the Trustee for any other cause, a successor Trustee may be appointed
by the Administrative Agent with the consent of the Company, which consent shall
not be unreasonably withheld. The powers, duties, authority and title of the
predecessor Trustee shall be terminated and cancelled without procuring the
resignation of such predecessor and without any other formality (except as may
be required by applicable law) than appointment and designation of a successor
in writing duly acknowledged and delivered to the predecessor and the Company.
Such appointment and designation shall be full evidence of the right and
authority to make the same and of all the facts therein recited, and this Trust
Agreement and the Trust Security Agreements shall vest in such successor,
without any further act, deed or conveyance, all the estates, properties,
rights, powers, trusts, duties, authority and title of its predecessor; but such
predecessor shall, nevertheless, on the written request of the Administrative
Agent, the Company, or the successor, execute and deliver an instrument
transferring to such successor all the estates, properties, rights, powers,
trusts, duties, authority and title of such predecessor hereunder and under the
Trust Security Documents and shall deliver all Collateral held by it or its
agents to such successor. Should any deed, conveyance or other instrument in
writing from any Obligor be required by any successor Trustee for more fully and
certainly vesting in such successor the estates, properties, rights, powers,
trusts, duties, authority and title vested or intended to be vested in the
predecessor

                                     -24-
<PAGE>

Trustee, any and all such deeds, conveyances and other instruments in writing
shall, on request of such successor, be executed, acknowledged and delivered by
such Obligor. If such Obligor shall not have executed and delivered any such
deed, conveyance or other instrument within 10 days after it received a written
request from the successor Trustee to do so, or if a Notice of Acceleration is
in effect, the predecessor Trustee may execute the same on behalf of such
Obligor. Such Obligor hereby appoints any predecessor Trustee as its agent and
attorney to act for it as provided in the next preceding sentence.

          5.8   Status of Successor Trustee.  Every successor Trustee appointed
          ---------------------------------
pursuant to Section 5.7 shall be a bank or trust company in good standing and
having power to act as Trustee hereunder, incorporated under the laws of the
United States of America or any State thereof or the District of Columbia and
having its principal corporate trust office within the 48 contiguous States and
shall also have capital, surplus and undivided profits of not less than
$100,000,000, if there be such an institution with such capital, surplus and
undivided profits willing, qualified and able to accept the trust hereunder upon
reasonable or customary terms.

          5.9   Merger of the Trustee.  Any corporation into which the Trustee
          ---------------------------
may be merged, or with which it may be consolidated, or any corporation
resulting from any merger or consolidation to which the Trustee shall be a
party, shall be Trustee under this Trust Agreement and the Trust Security
Documents without the execution or filing of any paper or any further act on the
part of the parties hereto.

          5.10  Co-Trustee; Separate Trustee.  (a)  If at any time or times it
          ----------------------------------
shall be necessary or prudent in order to conform to any law of any jurisdiction
in which any of the Collateral shall be located, or to avoid any violation of
law or imposition on the Trustee of taxes by such jurisdiction not otherwise
imposed on the Trustee, or the Trustee shall be advised by counsel, satisfactory
to it, that it is necessary or prudent in the interest of the Secured Parties,
or the Administrative Agent or any Surety Party shall in writing so request the
Trustee and the Obligors, or the Trustee shall deem it desirable for its own
protection in the performance of its duties hereunder or under any Trust
Security Document, the Trustee and each of the Obligors shall execute and
deliver all instruments and agreements necessary or proper to constitute another
bank or trust company, or one or more persons approved by the Trustee and the
Obligors, either to act as co-trustee or co-trustees of all or any of the
Collateral under this Trust Agreement or under any of the Trust Security
Documents, jointly with the Trustee originally named herein or therein or any
successor Trustee, or to act as separate trustee or trustees of any of the
Collateral. If any of the Obligors shall not have joined in the execution of
such instruments and agreements within 10 days after it receives a written
request from the Trustee to do so, or if a Notice of Acceleration is in effect,
the Trustee may act under the foregoing provisions of this Section 5.10(a)
without the concurrence of such Obligors and execute and deliver such
instruments and agreements on behalf of such Obligors. Each of the Obligors
hereby appoints the Trustee as its agent and attorney to act for it under the
foregoing provisions of this Section 5.10(a) in either of such contingencies.

          (b)   Every separate trustee and every co-trustee, other than any
successor Trustee appointed pursuant to Section 5.7, shall, to the extent
permitted by law, be appointed and act and be such, subject to the following
provisions and conditions:

                                     -25-

     Trustee in respect of the custody, control and management of moneys, papers
     or securities shall be exercised solely by the Trustee or any agent
     appointed by the Trustee;

          (ii)  all rights, powers, duties and obligations conferred or imposed
     upon the Trustee hereunder and under the relevant Trust Security Document
     or Documents shall be conferred or imposed and exercised or performed by

     co-trustees, jointly, as shall be provided in the instrument appointing
     such separate trustee or separate trustees or co-trustee or co-trustees,
     except to the extent that under any law of any jurisdiction in which any
     particular act or acts are to be performed the Trustee shall be incompetent
     or unqualified to perform such act or acts, or unless the performance of
     such act or acts would result in the imposition of any tax on the Trustee
     which would not be imposed absent such joint act or acts, in which event
     such rights, powers, duties and obligations shall be exercised and
     performed by such separate trustee or separate trustees or co-trustee or
     co-trustees;

          (iii) no power given hereby or by the relevant Trust Security
     Documents to, or which it is provided herein or therein may be exercised
     by, any such co-trustee or co-trustees or separate trustee or separate
     trustees shall be exercised hereunder or thereunder by such co-trustee or
     co-trustees or separate trustee or separate trustees except jointly with,
     or with the consent in writing of, the Trustee, anything contained herein
     to the contrary notwithstanding;

          (iv)  no trustee hereunder shall be personally liable by reason of any
     act or omission of any other trustee hereunder; and

          (v)   the Company and the Trustee, at any time by an instrument in

     any such separate trustee or co-trustee and, in that case by an instrument
     in writing executed by them jointly, may appoint a successor to such
     separate trustee or co-trustee, as the case may be, anything contained
     herein to the contrary notwithstanding. If the Company shall not have
     joined in the execution of any such instrument within 10 days after it
     receives a written request from the Trustee to do so, or if a Notice of
     Acceleration is in effect, the Trustee shall have the power to accept the
     resignation of or remove any such separate trustee or co-trustee and to
     appoint a successor without the concurrence of the Company, the Company
     hereby appointing the Trustee its agent and attorney to act for it in such
     connection in such contingency. If the Trustee shall have appointed a
     separate trustee or separate trustees or co-trustee or co-trustees as above
     provided, the Trustee may at any time, by an instrument in writing, accept
     the resignation of or remove any such separate trustee or co-trustee and
     the successor to any such separate trustee or co-trustee shall be appointed
     by the Company and the Trustee, or by the Trustee alone pursuant to this
     Section 5.10(b).

          -------------------------------------------------------------------
Secured Parties.  (a) The Trustee may treat the registered holder or, if none,

Obligation as the absolute owner thereof for all purposes and shall not be
affected by any notice to the contrary, whether such promissory note or
debenture shall be past due or not.

more Secured Parties to act as such in connection with any matters pertaining to
this Trust Agreement or the Collateral shall present to the Trustee such
documents, including, without limitation, Opinions of Counsel, as the Trustee
may reasonably require, in order to demonstrate to the Trustee the authority of
such Person to act as the representative of such Secured Parties (it being
understood that (i) the holders of Credit Agreement Obligations are represented
hereunder by the Administrative Agent and the holders of the Surety Bond
Obligations are represented hereunder by the relevant Surety Party and (ii) such
holders shall have no other rights pursuant to this Section 5.11(b)). The
authority of the Administrative Agent and each Surety Party shall be
