<PAGE>

          Section 2.2 Certain Representations and Warranties. The Collateral
Trustee represents and warrants to the Secured Parties as follows:

          (a) The Collateral Trustee is a national banking association organized
under the laws of the United States and has all required corporate power and
authority to enter into and perform its obligations under this Agreement and any
other Shared Collateral Document to which it is or may become a party.

          (b) The execution, delivery and performance by the Collateral Trustee
of this Agreement and any other Shared Collateral Document to which it (i) is a
party have been duly authorized by all necessary corporate action on the part of
the Collateral Trustee and (ii) becomes a party will be duly authorized by all
necessary corporate action on the part of the Collateral Trustee.

          (c) There are no actions or proceedings pending or, to its knowledge,
threatened against it before any Governmental Authority (i) which question the
validity or enforceability of this Agreement or any other Shared Collateral
Document to which it is a party; or (ii) which relate to the banking or trust
powers of the Collateral Trustee and which, if determined adversely to the
position of the Collateral Trustee, would materially and adversely affect the
ability of the Collateral Trustee to perform its obligations under this
Agreement or any of the other Shared Collateral Documents to which it is a
party.

          (d) This Agreement and all of the other Shared Collateral Documents to
which the Collateral Trustee is a party have been duly executed and delivered by

          Section 2.3 Actions.

                    Until the payment in full of the Senior Secured Obligations
as notified to the Collateral Trustee in writing by the Bank Administrative
Agent and (i) prior to the Collateral Trustee's receipt of a Notice of
Actionable Default or (ii) after the withdrawal of all pending Notices of
Actionable Default in accordance with the terms of Section 3.2(b) and prior to
the Collateral Trustee's receipt of any additional Notice of Actionable Default,
the Collateral Trustee shall take any action with respect to the Shared
Collateral and the Shared Collateral Documents requested in writing by the Bank
Administrative Agent or, after the Credit Agreement Termination Date, the
Requisite Obligees; provided, however, that the Collateral Trustee shall not be
obligated to take any such action which is in conflict with provisions of law or
the Shared Collateral Documents, is prohibited by order of any court or
Governmental Authority or with respect to which the Collateral Trustee has not
received adequate security or indemnity as provided in Section 6.4(d).

          Section 2.4 Limitation on Duties. The Collateral Trustee's sole duty
with respect to the custody, safekeeping and physical preservation of the Shared
Collateral in its possession shall be to deal with it in the same manner as the
Collateral Trustee deals with similar property for its own account. Neither the
Collateral Trustee, any other Secured Party nor any of their respective
officers, directors, employees or agents shall be liable for failure to demand,
collect or realize upon any of the Shared Collateral or for any delay in doing
so or shall be under any obligation to sell or otherwise dispose of any Shared
Collateral upon the request of any Grantor or any other Person (except pursuant
to Section 2.3, Article III or Article VII) or to take any other action
whatsoever with regard to the Shared Collateral or any part thereof. The powers
conferred on the Collateral Trustee hereunder are solely to protect the
Collateral Trustee's interest in the Shared Collateral and shall not impose any
duty upon the Collateral Trustee or any other

                                       10

<PAGE>

Secured Party to exercise any such powers. The Collateral Trustee and the other
Secured Parties shall be accountable only for amounts that they actually receive
as a result of the exercise of such powers, and neither they nor any of their
officers, directors, employees or agents shall be responsible to any Grantor for
any act or failure to act hereunder, except for their own gross negligence or
willful misconduct.

          ARTICLE III. Actionable Defaults; Remedies

          (a) Subject to Section 3.1(c), if the Collateral Trustee shall have
received a Notice of Actionable Default based on a Credit Event of Default from
the Bank Administrative Agent and so long as (i) such Notice of Actionable
Default has not been withdrawn in accordance with the provisions of Section

Default has been received from the 1992 Indenture Trustee, the 1996 Indenture
Trustee, or the Senior Note Indenture Trustee, the Bank Administrative Agent
shall have the right, by an instrument in writing executed and delivered to the
Collateral Trustee, to direct the Collateral Trustee to exercise, or to refrain
from exercising, any right, remedy, trust or power available to or conferred
upon the Collateral Trustee hereunder or under any Shared Collateral Document
and in connection therewith, to direct the time, method and place of conducting
any proceeding for any right or remedy available to the Collateral Trustee, or
of exercising any trust or power conferred on the Collateral Trustee, or for the
appointment of a receiver, or for the taking of any other action authorized by
this Agreement or any Shared Collateral Document; provided, however, that the
Collateral Trustee shall have received adequate security or indemnity as
provided in Section 6.4(d) of this Agreement.

          (b) Subject to Section 3.1(c), if the Collateral Trustee shall have
received a Notice of Actionable Default based on an Indenture Event of Default
from the 1992 Indenture Trustee, the 1996 Indenture Trustee, or the Senior Note
Indenture Trustee, irrespective of whether the Bank Administrative Agent has
submitted a Notice of Actionable Default, and so long as such Notice of
Actionable Default has not been withdrawn in accordance with the provisions of
Section 3.2(b), the representatives of more than 50% of the aggregate principal
amount of the Secured Debt (collectively, the "Required Holders of Secured
Debt") shall, by an instrument in writing executed and delivered to the
Collateral Trustee, direct the Collateral Trustee to exercise, or to refrain
from exercising, any right, remedy, trust or power available to or conferred
upon the Collateral Trustee hereunder or under any Shared Collateral Document
and in connection therewith, to direct the time, method and place of conducting
any proceeding for any right or remedy available to the Collateral Trustee, or
of exercising any trust or power conferred on the Collateral Trustee, or for the
appointment of a receiver, or for the taking of any other action authorized by
this Agreement or any Shared Collateral Document; provided, however, that the
Collateral Trustee shall have received adequate security or indemnity as
provided in Section 6.4(d) of this Agreement.

          (c) The Collateral Trustee shall not be obligated to follow any
written directions received pursuant to Section 3.1(a), Section 3.1(b) or
Section 3.4 of this Agreement to the extent the Collateral Trustee has received
a written opinion of its counsel, which counsel shall be reasonably satisfactory
to the Bank Administrative Agent, the 1992 Indenture Trustee, the 1996 Indenture
Trustee, and the Senior Note Indenture Trustee to the effect that such
directions are in conflict with any provisions of law or any applicable Shared
Collateral Document or any order of any court or Governmental Authority;
provided, however, under no circumstances shall the Collateral Trustee be liable
for following such written directions of the Bank Administrative

                                       11

<PAGE>

Agent, the 1992 Indenture Trustee, the 1996 Indenture Trustee, or the Senior
Note Indenture Trustee, as the case may be.

          Nothing in this Section 3.1 shall impair the right of the Collateral
Trustee in its discretion to take or omit to take any action which is deemed
proper by the Collateral Trustee and which it believes in good faith is not
inconsistent with any direction of the Bank Administrative Agent or the Required
Holders of Secured Debt delivered pursuant to this Section 3.1; provided,
however, the Collateral Trustee shall not be under any obligation, as a result
of this Section 3.1 or any other provision of this Agreement, to take any action
which is discretionary with the Collateral Trustee under the provisions hereof
or under any other Shared Collateral Document unless so directed by the Bank
Administrative Agent or the Required Holders of Secured Debt, as applicable.

          Section 3.2 Notice of Actionable Default.

          (a) Upon receipt of a Notice of Actionable Default, the Collateral
Trustee shall, within five (5) Business Days thereafter, notify each Secured
Party and each Grantor in the manner provided in Section 8.2 of this Agreement
that a Notice of Actionable Default has been received. Upon receipt of any
written directions pursuant to Section 3.1(a) or Section 3.1(b) of this
Agreement, the Collateral Trustee shall, within five (5) Business Days
thereafter, send a copy thereof to each Secured Party and each Grantor in the
manner provided in Section 8.2 of this Agreement; provided, however, that the
failures of the Collateral Trustee to send such copy shall not impair any of the
rights, powers and remedies of the Collateral Trustee under any Shared
Collateral Documents.

          (b) The party (or successors in interest thereto) giving a Notice of
Actionable Default shall be entitled, or required if the Actionable Default
shall no longer be continuing, to withdraw it by delivering written notice of
withdrawal to the Collateral Trustee (i) before the Collateral Trustee takes any
action to exercise any remedy with respect to the Shared Collateral or (ii)
thereafter if the Grantors otherwise indemnify the Collateral Trustee and the
Secured Parties (in a manner satisfactory to the Collateral Trustee and the
Secured Parties in their sole discretion) with respect to all costs and expenses
incurred by the Collateral Trustee and the Secured Parties in connection with
reversing all actions the Collateral Trustee or any Secured Party has taken to
exercise any remedy or remedies with respect to the Shared Collateral. The
Collateral Trustee shall immediately notify each Grantor as to the receipt and
contents of any such notice of withdrawal and shall promptly notify each Secured
Party, in the manner provided in Section 8.2 of this Agreement, of the
withdrawal of any Notice of Actionable Default. The failure of the Collateral
Trustee to send a copy or notice required pursuant to this Section 3.2 shall not
impair any of the rights, powers and remedies of the Collateral Trustee under
any Shared Collateral Document.

          (c) To the extent that any Notice of Actionable Default shall give
rise to any of the rights and remedies provided in this Agreement or any other
Shared Collateral Document or shall prohibit any Grantor from taking certain
actions as specified herein or therein, such rights and remedies shall be
suspended, any exercise thereof by the Collateral Trustee shall cease, and such
prohibition on the Grantors shall not remain in effect upon receipt by the
Collateral Trustee of written notice of withdrawal of such Notice of Actionable
Default pursuant to the terms and provisions of Section 3.2(b); provided,
however, that such rights and remedies, and such prohibitions, shall be
reinstated upon the giving of any later Notice of Actionable Default.

Administrative Agent or the Required Holders of Secured Debt, as the case may

existing at law or in equity or by statute.

          (b) No delay or omission by the Collateral Trustee in the exercise of
any right, remedy or power accruing upon an Actionable Default shall impair any
such right, remedy or power or shall be construed to be a waiver of any
Actionable Default or an acquiescence therein; and every right, power and remedy
given by any Shared Collateral Document to the Collateral Trustee may be
exercised from time to time and as often as may be deemed expedient by the
Collateral Trustee.

          (c) In case the Collateral Trustee shall have proceeded to enforce any
right, remedy or power under any Shared Collateral 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 Collateral Trustee, then
and in every such case the Grantors, the Collateral Trustee and the Secured
Parties shall, subject to any effect of or determination in such proceeding,
severally and respectively be restored to their former positions and rights
under the Shared Collateral Documents with respect to the Trust Estate and in
all other respects, and thereafter all rights, remedies and powers of the
Collateral Trustee shall continue as though no such proceeding had been taken.

          (d) All rights of action and rights to assert claims upon or under the
Shared Collateral Documents may be enforced by the Collateral Trustee without
the possession of any Secured Debt Instrument or the production thereof in any
trial or other proceeding relative thereto, and any such suit or proceeding
instituted by the Collateral Trustee shall be brought in its name as the
Collateral Trustee and any recovery of judgment shall be held as part of the
Trust Estate.

          Section 3.8 Limitation by Law. All the provisions of this Article III
are intended to be subject to all applicable mandatory provisions of law which
may be controlling in the premises and to be limited to the extent necessary so
that they will not render this Agreement invalid or unenforceable in whole or in
part.

          Section 3.9 Absolute Rights of Secured Parties. Notwithstanding any
other provision of any Shared Collateral Document, but subject in all cases to
the rights of the Bank Administrative Agent and the Required Holders of Secured
Debt under Section 3.1, neither (i) the right of each Secured Party, which is
absolute and unconditional, to receive payments of the Secured Debt held by such
Secured Party on or after the due date thereof as expressed in the Secured Debt
Instruments, to institute suit for the enforcement of such payment on or after
such due date, or to assert its position and views as a secured creditor in, and
to otherwise exercise any right (other than the right to enforce any Lien on the
Shared Collateral, which shall in all circumstances be exercisable only by the
Collateral Trustee) it may have in connection with, a

                                       15

<PAGE>

case under the Bankruptcy Code in which a Grantor is a debtor, nor (ii) the
obligation of each Grantor, which is also absolute and unconditional, to pay the
Secured Debt owing by such Grantor to each Secured Party at the time and place
expressed in the Secured Debt Instruments, shall be impaired or affected without
the written consent of such Secured Party.

          Section 3.10 Restatement of Rights. The provisions of this Agreement
shall continue to be effective or be reinstated, as the case may be, if at any
time any payment of Secured Debt is rescinded or must otherwise be returned by
the Collateral Trustee or any Secured Party upon the insolvency, bankruptcy or
reorganization of a Grantor or otherwise, all as though such payment had not
been made.

          ARTICLE IV. PRIORITY; COLLATERAL ACCOUNT; APPLICATION OF MONEYS

          Section 4.1 Priority of Security Interests. Notwithstanding (i) the
time, order, manner or method of creation, attachment or perfection of the
respective security interests and/or liens granted to any Secured Party in or on
any or all of the property or assets of the Grantors, (ii) the time or manner of
the filing of the financing statements reflecting such security interests, (iii)
whether any Secured Party or any bailee or agent thereof holds possession of any
or all of the property or assets of the Grantors, (iv) the dating, execution or
delivery of any agreement, document or instrument granting any Secured Party
security interests and/or liens in or on any or all of the property or assets of
the Grantors and (v) any provision of the UCC or any other applicable law to the
contrary, the Collateral Trustee on behalf of itself and on behalf of the Senior
Lenders and the Bank Administrative Agent shall have a first priority security
interest in the Senior Priority Collateral. Any and all security interests,
liens, rights and interests of the 1992 Indenture Trustee, the 1996 Indenture
Trustee, the Senior Note Indenture Trustee, the holders of the 1992 Notes, the
holders of the 1996 Notes and/or holders of the Senior Notes, whether now or
hereafter arising and howsoever existing, in or on any or all of the Shared
Collateral, shall be and hereby are subordinated to any and all security
interests, liens, rights and interests of the Senior Lenders, the Collateral
Trustee and the Bank Administrative Agent in and to the Senior Priority
Collateral. For purposes of the foregoing allocation of priorities, any claim of
a right of setoff shall be treated in all respects as a security interest and no
claimed right of setoff shall be asserted to defeat or diminish the rights or
priorities provided for herein.

          Section 4.2 The Collateral Account. There has been established by the
Collateral Trustee and, at all times hereafter until the trusts created by this
Agreement shall have terminated, there shall be maintained with the Collateral
Trustee a non-interest bearing trust account which is entitled the "FMC
Collateral Account" (herein called the "Collateral Account"). During the
continuance of an Actionable Default, all moneys received by the Collateral
Trustee with respect to all or any part of the Shared Collateral shall be
deposited in the Collateral Account and thereafter shall be held, applied and/or
disbursed by the Collateral Trustee in accordance with the terms of Section 4.5
of this Agreement.

          Section 4.3 Control of Collateral Account. All right, title and
interest in and to the Collateral Account shall vest in the Collateral Trustee,
and funds on deposit 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 Collateral Trustee.

          Section 4.4 Investment of Funds Deposited in Collateral Account. The
Collateral Trustee shall invest and reinvest moneys on deposit in the Collateral
Account at any time in one or more Cash Equivalents and, so long as no
Actionable Default has occurred, as

                                       16

<PAGE>

directed in writing by FMC and, during an Actionable Default, as directed in
writing by the Bank Administrative Agent; provided, however, that in order to
provide the Secured Parties with a perfected security interest therein:

          (a) each such investment shall be evidenced, or deemed under
applicable federal regulations to be evidenced, by negotiable certificates or
instruments or nonnegotiable certificates or instruments issued in the name of
the Collateral Trustee or its nominee, which (together with any appropriate
instruments of transfer) are delivered to, and held by, the Collateral Trustee
or an agent thereof (which shall not be any Grantor or any of its affiliates);
or

          (b) each such investment shall be held in the Collateral Account or
other Securities Accounts in the name of the Collateral Trustee or its nominee,
with respect to which accounts the Collateral Trustee shall be the sole
entitlement holder and the only person authorized to give entitlement orders.

All such investments and the interest and income received thereon and therefrom
and the net proceeds realized on the sale hereof shall be held in the Collateral
Account as part of the Trust Estate. Neither the Collateral Trustee nor the Bank
Administrative Agent shall be liable for losses with respect to investments made
hereunder.

          Section 4.5 Application of Moneys.

          (a) Subject to Section 4.2, all moneys held by the Collateral Trustee
in the Collateral Account shall, to the extent available for distribution, be
distributed by the Collateral Trustee on the first and each succeeding
Distribution Date until the payment in full of the Senior Secured Obligations as
follows:

          FIRST: To the Collateral Trustee in an amount equal to the Collateral
Trustee's Fees which are unpaid as of such Distribution Date, then to any
Secured Party which has theretofore advanced or paid any such Collateral
Trustee's Fees in an amount equal to the amount thereof so advanced or paid by
such Secured Party prior to such Distribution Date; provided, however, that
nothing herein is intended to relieve any Grantor of its obligation to pay such
costs, fees, expenses and liabilities from funds outside of the Collateral
Account;

          SECOND: To the Bank Administrative Agent, for the benefit of itself
and the Senior Lenders, up to an amount equal to any outstanding Senior Secured
Obligations; provided, that such aggregate amounts distributed on a
first-priority basis pursuant to this clause to the Bank Administrative Agent
shall not exceed the amount of the Senior Priority Collateral; and

          THIRD: To the Secured Parties up to an amount equal to any
outstanding, Senior Secured Obligations, 1992 Note Obligations, 1996 Note
Obligations and Senior Note Obligations, and, if such moneys shall be
insufficient to pay such amounts, in full, then ratably to the Secured Parties
in proportion to the unpaid amounts of the Senior Secured Obligations, 1992 Note
Obligations, the 1996 Note Obligations and the Senior Note Obligations; and

          FOURTH: Any surplus then remaining shall be paid to the Grantors or
their successors or assigns, or to whomever may be lawfully entitled to receive
the same or as a court of competent jurisdiction may direct; provided, however,
that if any Secured Party with rights in the Shared Collateral shall have
notified the Collateral Trustee in writing that such Secured Party is entitled
to the benefits of an indemnification, reimbursement or similar provision under
which amounts are not yet due but with respect to which any Grantor continues to
be contingently liable,

                                       17

<PAGE>

and amounts payable by such Grantor with respect thereto are secured by the
Trust Estate, the Collateral Trustee shall continue to hold the amount specified
in such notice in the Collateral Account until such Grantor's liability with
respect thereto is discharged or released to the satisfaction of such Secured
Party.

          (b) The Secured Parties have agreed and acknowledged that the
provisions of this Section 4.5 are for their benefit and that if any Secured
Party shall receive any moneys contrary to the provisions of this Agreement,
such Secured Party shall forthwith turn such moneys over to the Collateral
Trustee to be distributed in accordance with the provisions of this Agreement.

          ARTICLE V. AGREEMENT WITH COLLATERAL TRUSTEE

          Section 5.1 Delivery of Secured Debt Instruments. On the date of this
Agreement, the Grantors shall deliver to the Collateral Trustee a true and
complete copy of the Secured Debt Instruments, an executed counterpart of any
Shared Collateral Documents and any Pledged Collateral and other Shared
Collateral to be delivered pursuant thereto, all of which shall be identified on
Schedule B hereto. Each Grantor agrees that it will deliver to the Collateral
Trustee (i) promptly upon the execution thereof, a true and complete copy of any
and all amendments, modifications or supplements to any Secured Debt Instrument
or Shared Collateral Documents entered into by such Grantor subsequent to the
date of this Agreement and (ii) when required by the Shared Collateral
Documents, any Pledged Collateral or other Shared Collateral to be delivered
pursuant thereto.

          Section 5.2 Compensation and Expenses. The Grantors jointly and
severally agree to pay to the Collateral Trustee (i) the Collateral Trustee's
Fees as compensation for the Collateral Trustee's services hereunder and under
the other Shared Collateral Documents and for accepting and administering the
Trust Estate as shall be mutually agreed by the Grantors and the Collateral
Trustee and (ii) from time to time, upon demand, all of the fees, costs and
expenses of the Collateral Trustee (including, without limitation, the
reasonable fees and disbursements of its counsel and such special counsel as the
Collateral Trustee elects to retain) (A) arising in connection with the
preparation, execution, delivery, modification, restatement, amendment or
termination of this Agreement and each other Shared Collateral Document or the
enforcement (whether in the context of a civil action, adversary proceeding,
workout or otherwise) of any of the provisions hereof or thereof, or (B)
incurred or required to be advanced in connection with the administration of the
Trust Estate, the sale or other disposition or the custody, preservation or
protection of Shared Collateral pursuant to any Shared Collateral Document
(including, without limitation, in connection with actions taken by the
Collateral Trustee pursuant to Section 3.3) and the exercise or enforcement of
the Collateral Trustee's rights under any Shared Collateral Document and in and
to the Shared Collateral and the Trust Estate. As security for such payment and
the payment of the obligations set forth in Sections 5.3 and 5.4, the Collateral
Trustee shall have a Lien prior to the Secured Debt upon all Shared Collateral
and other property and funds held or collected by the Collateral Trustee as part
of the Trust Estate. The obligations of the Grantors to pay amounts due under
this Section 5.2 shall survive the termination of this Agreement and the
resignation or removal of the Collateral Trustee.

          Section 5.3 Stamp and Other Similar Taxes. The Grantors jointly and
severally agree to upon demand indemnify and hold harmless the Collateral
Trustee and each Secured Party from, and shall reimburse the Collateral Trustee
and each Secured Party for, any present or future claim for liability for any
stamp or other similar tax and any penalties or interest with respect thereto
which may be assessed, levied or collected by any jurisdiction in connection

                                       18

<PAGE>

with any Shared Collateral Document, the Trust Estate or the attachment or
perfection of the security interest granted to the Collateral Trustee in any
Shared Collateral. The obligations of the Grantors under this Section 5.3 shall
survive the termination of the other provisions of this Agreement and the
resignation or removal of the Collateral Trustee.

          Section 5.4 Filing Fees, Excise Taxes, etc. The Grantors agree to pay
or to reimburse the Collateral Trustee and each Secured Party for any and all
amounts in respect of all search, filing, recording and registration fees,
taxes, excise taxes and other similar imposts which may be payable or determined
to be payable in respect of the execution, delivery, performance and enforcement
of each Shared Collateral Document and agree to save the Collateral Trustee and
each Secured Party harmless from and against any and all liabilities with
respect to or resulting from any delay in paying or omission to pay such taxes
and fees. The obligations of the Grantors under this Section 5.4 shall survive
the termination of the other provisions of this Agreement and the resignation or
removal of the Collateral Trustee.

          Section 5.5 Indemnification.

          (a) The Grantors jointly and severally agree to pay, and indemnify and
hold harmless the Collateral Trustee and each of its employees and agents from
and against, any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, amounts paid in settlements, suits, costs, expenses or
disbursements of any kind or nature whatsoever with respect to the execution,
delivery, enforcement, performance and administration of the Shared Collateral
Documents, the Shared Collateral and the Trust Estate, except to the extent
arising from the gross negligence, willful misconduct or willful breach of this
Agreement of such Persons as are seeking indemnification. As security for such
payment, the Collateral Trustee shall have a Lien prior to the Secured Debt upon
all Shared Collateral and other property and funds held or collected by the
Collateral Trustee as part of the Trust Estate.

          (b) In any suit, proceeding or action brought by the Collateral
Trustee under or with respect to the Shared Collateral for any sum owing
thereunder, or to enforce any provisions thereof, or of any of the Shared
Collateral Documents, the Grantors will jointly and severally save, indemnify
and keep the Collateral Trustee harmless from and against all expense, loss or
damage suffered by reason of any defense, set-off, counterclaim, recoupment or
reduction of liability whatsoever of the obligee thereunder, arising out of a
breach by any Grantor of any of its obligations thereunder or arising out of any
other agreement, indebtedness or liability at any time owing to or in favor of
such obligee or its successors from the Grantors, and all such obligations of
the Grantors shall be and remain enforceable against and only against the
Grantors and shall not be enforceable against the Collateral Trustee.

          (c) If and to the extent that the obligations of the Grantors under
this Section 5.5 are unenforceable for any reason, each Grantor hereby agrees to
make the maximum contribution to the payment and satisfaction of such
obligations which is permissible under applicable law.

          (d) The agreements in this Section 5.5 shall survive the termination
of the other provisions of this Agreement and the resignation or removal of the
Collateral Trustee.

          Section 5.6 Further Assurances. At any time and from time to time,
upon the written request of the Collateral Trustee or when necessary, and at the
expense of the Grantors, each Grantor will promptly execute and deliver any and
all such further instruments and documents and take such further action as may
be necessary or as the Collateral Trustee may

                                       19

<PAGE>

reasonably request to obtain the full benefits of the Shared Collateral
Documents and the rights and powers therein granted, including, without
limitation, the filing of any financing or continuation statements or other
instruments to perfect the Liens and security interests granted thereby. Each
Grantor shall, not later than thirty (30) days after the Collateral Trustee's
request therefor, deliver to the Collateral Trustee an opinion of counsel, which
counsel shall be reasonably satisfactory to the Bank Administrative Agent, the
1992 Indenture Trustee, the 1996 Indenture Trustee, and the Senior Note
Indenture Trustee, addressed to the Collateral Trustee for the benefit of the
Secured Parties, concerning the continued perfection of the Liens and security
interests created by the Shared Collateral Documents (excluding, however, those
Liens and security interests which, in accordance with the terms of the Shared
Collateral Documents, have been released); provided, however, that (a) the
Collateral Trustee may not request such opinion from any Grantor more than one
(1) time during any calendar year, and (b) the Collateral Trustee shall have no
obligation at any time to request such opinion from any Grantor. Each Grantor
shall, in all of its published financial statements customarily prepared with
footnotes or filed with the Securities and Exchange Commission, indicate by
footnote or otherwise that the Secured Debt is secured pursuant to the Shared
Collateral Documents.

          ARTICLE VI. COLLATERAL TRUSTEE

          Section 6.1 Appointment of Collateral Trustee and Acceptance of Trust.
Each of the Bank Administrative Agent, on behalf of the Senior Lenders, the 1992
Indenture Trustee on behalf of the holders of the 1992 Notes, the 1996 Indenture
Trustee on behalf of the 1996 Notes, and the Senior Note Indenture Trustee on
behalf of the Senior Notes, hereby appoint the Collateral Trustee under the
terms and conditions of this Agreement, and the Collateral Trustee, for itself
and its successors, hereby accepts the trusts created by this Agreement upon the
terms and conditions hereof, including those contained in this Article VI.

          Section 6.2 Exculpatory Provisions.

          (a) The Collateral Trustee shall not be responsible in any manner
whatsoever for the correctness of any recitals, statements, representations or
warranties contained in any of the Shared Collateral Documents, except for those
made by the Collateral Trustee. The Collateral Trustee makes no representations
as to the value or condition of the Trust Estate or any part thereof, or as to
the title of any of the Grantors thereto or as to the security afforded by the
Shared Collateral Documents or, except as expressly set forth in Section 2.2 of
this Agreement, as to the validity, execution, enforceability, legality,
perfection, priority or sufficiency of any Shared Collateral Document or of the
Secured Debt secured thereby, and the Collateral Trustee shall incur no
liability or responsibility in respect of any such matters. The Collateral
Trustee shall not be responsible for insuring, or monitoring or maintaining the
insurance on, the Trust Estate or for the payment of taxes, charges, assessments
or Liens upon the Trust Estate or otherwise as to the maintenance of the Trust
Estate, except that (i) in the event the Collateral Trustee enters into
possession of a part or all of the Trust Estate, the Collateral Trustee shall
preserve the part in its possession, and (ii) the Collateral Trustee will
promptly take such action as the Bank Administrative Agent shall request to
remove and discharge (by bonding or otherwise) any Lien on any part of the Trust
Estate resulting from claims against it (whether individually or as Collateral
Trustee) not related to the administration of the Trust Estate or (if so
related) resulting from gross negligence or willful misconduct on its part.
Notwithstanding anything to the contrary contained in this Agreement and in
furtherance of the immediately preceding sentence, the Collateral Trustee shall
not be responsible for the attachment, perfection, priority or enforceability of
any Lien created or purported to be created by any Shared Collateral Document,
the adequacy, sufficiency or effectiveness of any Shared Collateral Document or
the value of any

                                       20

<PAGE>

Shared Collateral granted pursuant to any Shared Collateral Document from time
to time. The Collateral Trustee shall not be responsible for the filing or
recording of any financing statement, mortgage, security agreement or any other
Shared Collateral Document in any public office or for the maintaining of any
records of any such filings or recordings, nor shall the Collateral Trustee have
any duty to file or record, or to advise the Secured Parties of the need to file
or record, any continuation statements or other public notices relating to the
perfection or continued perfection of any Shared Collateral.

          (b) The Collateral Trustee shall not be required to ascertain or
inquire as to the performance by any Grantor of any of the covenants or
agreements contained in any Shared Collateral Document or in any Secured Debt
Instrument. Without limiting the foregoing, the Collateral Trustee shall have no
duty to (i) enforce any obligations of the Grantors to deliver any agreement,
instrument, document, certificate, schedule, list, opinion of counsel or other
items required to be delivered to the Collateral Trustee hereunder, (ii) advise
any Secured Party of the failure of any Grantor to deliver the same or (iii) to
monitor compliance by the Grantors of any requirement to maintain insurance on
any of the Shared Collateral. Whenever it is necessary, or in the opinion of the
Collateral Trustee advisable, for the Collateral Trustee to ascertain the
identity of any Secured Party or the amount of Secured Debt then held by a
Secured Party, the Collateral Trustee may rely on a certificate of such Secured
Party.

          (c) Subject to the provisions of applicable law concerning the
Collateral Trustee's duty of care with respect to certificates and notes
evidencing the Pledged Collateral in the Collateral Trustee's possession, the
Collateral Trustee shall not be personally liable for any acts, omissions,
errors of judgment or mistakes of fact or law made, taken or omitted to be made
or taken by it in accordance with any Shared Collateral Document (including,
without limitation, acts, omissions, errors or mistakes with respect to the
Shared Collateral), except for those arising out of or in connection with the
Collateral Trustee's gross negligence or willful misconduct.

          Section 6.3 Delegation of Duties. The Collateral Trustee may execute
any of the trusts or powers hereof and perform any duty hereunder either
directly or by or through agents, nominees or attorneys-in-fact of its
selection, which may include employees or officers of any Grantor, provided,
that the Collateral Trustee shall obtain a written acknowledgment from such
agents, nominees or attorneys-in-fact that they shall be liable to the Secured
Parties for losses or damages incurred by any Secured Party as a result of such
agent's nominee's or attorneys-in-fact gross negligence or willful misconduct as
and to the extent the Collateral Trustee would be liable for such losses or
damages if the actions or omissions of such agents, nominees or
attorneys-in-fact constituting such gross negligence or willful misconduct had
been actions or omissions of the Collateral Trustee. The Collateral Trustee
shall be entitled to rely on advice of counsel concerning all matters pertaining
to such trusts, powers and duties. The Collateral Trustee shall not be
responsible for any negligence or misconduct of any agents, nominees or
attorneys-in-fact selected by it without gross negligence or willful misconduct.

          Section 6.4 Reliance by Collateral Trustee.

          (a) Whenever in the administration of the trusts of this Agreement the
Collateral Trustee shall deem it necessary or desirable that a matter be proved
or established with respect to any Grantor or any Person in connection with the
taking, suffering or omitting of any action hereunder by the Collateral Trustee,
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 of such Grantor or Person delivered to the
Collateral Trustee, and such certificate shall be full warranty to the
Collateral Trustee for any action taken, suffered

                                       21

<PAGE>

or omitted in reliance thereon; subject, however, to the provisions of Section
6.5(b) of this Agreement.

          (b) The Collateral Trustee may consult with its counsel, accountants
or other experts of its choice in connection with the fulfillment of its duties
hereunder, and the Collateral Trustee shall be entitled to rely on, and shall be
fully protected in acting upon, the opinion of such counsel, accountants or
other experts in connection with any action taken, omitted to be taken or
suffered by the Collateral Trustee in fulfillment of its duties hereunder. The
Collateral Trustee shall have the right at any time to seek instructions
concerning the administration of the Trust Estate from any court of competent
jurisdiction.

          (c) The Collateral Trustee may conclusively 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 does not in good faith 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, telecopies and telexes, to have been sent by the proper party or
parties. In the absence of its gross negligence or willful misconduct, the
Collateral 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 Collateral Trustee and conforming to the requirements
of any Shared Collateral Document.

          (d) If the Collateral Trustee has been requested or is otherwise
required hereby to take any action pursuant to this Agreement, the Collateral
Trustee shall not be under any obligation to exercise any of the rights or
powers vested in the Collateral Trustee by this Agreement or any Shared
Collateral Document or to otherwise take such action unless the Collateral
Trustee shall have been provided adequate security and indemnity satisfactory to
it against the costs, expenses and liabilities which may be incurred by it in
compliance with such request or direction or in taking such action, including
such reasonable advances as may be requested by the Collateral Trustee.

          Section 6.5 Limitations on Duties of Collateral Trustee.

          (a) No provision of this Agreement shall require the Collateral
Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers. The Collateral Trustee shall be obliged to
perform only such duties as are specifically set forth in this Agreement or any
Shared Collateral Document to which it is a party, and no implied covenants or
obligations shall be read into any Shared Collateral Document against the
Collateral Trustee. The Collateral Trustee shall, upon receipt of a Notice of
Actionable Default and during such time as such Notice of Actionable Default
shall not have been withdrawn in accordance with the provisions of Section
3.2(b) and unless prevented from doing so by applicable law or by order of a
court or other Governmental Authority, exercise the rights and powers vested in
it by any Shared Collateral Document, and the Collateral Trustee shall not be
liable with respect to any action taken or omitted by it in accordance with the
direction of the Bank Administrative Agent or the Required Holders of Secured
Debt pursuant to Section 3.1 of this Agreement. If at any time the Collateral
Trustee shall in accordance with the provisions hereof seek directions of the
Bank Administrative Agent or the Required Holders of Secured Debt with respect
to any such action to be taken or omitted by it under any of the Shared
Collateral Documents, the Collateral Trustee shall not be required to take or
omit such action until it shall have received such direction.

                                       22

<PAGE>

          (b) Except as herein otherwise expressly provided, including, without
limitation, upon the written direction of the Bank Administrative Agent pursuant
to Section 3.1 of this Agreement, the Collateral Trustee shall not be under any
obligation to take any action which is discretionary with the Collateral Trustee
under the provisions of any Shared Collateral Document. The Collateral Trustee
shall furnish to the Bank Administrative Agent or the Required Holders of
Secured Debt, promptly upon receipt thereof a copy of each certificate or other
paper furnished to the Collateral Trustee by any Grantor under or in respect of
any Shared Collateral Document or any of the Trust Estate, unless by the express
terms of any Shared Collateral Document a copy of the same is required to be
furnished by some other Person directly to the Bank Administrative Agent and the
Required Holders of Secured Debt, or the Collateral Trustee shall have
determined that the same has already been so furnished; provided, however, that
the Collateral Trustee shall have no liability for its inadvertent failure to
furnish any such Person with any such copies.

          Section 6.6 Moneys to be Held in Trust. All moneys received by the
Collateral Trustee under or pursuant to any provision of any Shared Collateral
Document shall be held in trust for the purposes for which they were paid or are
held.

          Section 6.7 Resignation and Removal of the Collateral Trustee.

          (a) The Collateral Trustee may at any time by giving sixty (60) days'
prior written notice to the Grantors and the Secured Parties, resign and be
discharged of the responsibilities hereby created, such resignation to become
effective upon the appointment of a successor Collateral Trustee. The Collateral
Trustee may be removed at any time and a successor Collateral Trustee appointed
by the Bank Administrative Agent or, after the Credit Agreement Termination
Date, the Requisite Obligees; provided, however, that the Collateral Trustee
shall be entitled to its fees and expenses to the date of removal; and,
provided, further, that the Collateral Trustee's rights pursuant to Section 8.5
shall survive with respect to any transaction or occurrence prior to the
effective date of such resignation or removal. If no successor Collateral
Trustee shall be appointed and approved within sixty (60) days from the date of
the giving of the aforesaid notice of resignation or within sixty (60) days from
the date of such removal, the Collateral Trustee shall, or any Secured Party
may, apply to any court of competent jurisdiction to appoint a successor
Collateral Trustee to act until such time, if any, as a successor Collateral
Trustee shall have been appointed as above provided. Any successor Collateral
Trustee so appointed by such court shall immediately and without further act be
superseded by any successor Collateral Trustee approved by the Bank
Administrative Agent, the 1992 Indenture Trustee, the 1996 Indenture Trustee and
the Senior Note Indenture Trustee as above provided.

          (b) If at any time the Collateral Trustee shall resign, be removed or
otherwise become incapable of acting, or if at any time a vacancy shall occur in
the office of the Collateral Trustee for any other cause, a successor Collateral
Trustee may be appointed by the Bank Administrative Agent or, after the Credit
Agreement Termination Date, the Requisite Obligees, and the powers, duties,
authority and title of the predecessor Collateral Trustee terminated and

Trustee in writing, duly acknowledged, delivered to the predecessor Collateral
Trustee and the Grantors, and filed for record in each applicable office, if

          (c) The appointment and designation referred to in Section 6.7(b) of
this Agreement shall, after any required filing, be full evidence of the right
and authority to make the same and all of the facts therein recited, and this
Agreement shall vest in such successor Collateral Trustee, without any further
act, deed or conveyance, all of the estate and title of its predecessors, and,
upon any required filing for record, the successor Collateral Trustee shall
become fully vested with all the estates, properties, rights, powers, trusts,
duties, authority and title of its predecessors; but any of such predecessors
shall, nevertheless, on the written request of the Bank Administrative Agent,
the 1992 Indenture Trustee, the 1996 Indenture Trustee, the Senior Note
Indenture Trustee, any Grantor or any successor Collateral Trustee, execute and
deliver an instrument transferring to such successor Collateral Trustee all the
estates, properties, rights, powers, trusts, duties, authority and title of such
predecessor hereunder and shall deliver all securities and moneys held by it to
such successor Collateral Trustee. Should any deed, conveyance or other
instrument in writing from any Grantor be required by any successor Collateral
Trustee for more fully and certainly vesting in such successor Collateral
Trustee the estates, properties, rights, powers, trusts, duties, authority and
title vested or intended to be vested in the predecessor Collateral Trustee, any
and all such deeds, conveyances and other instruments in writing shall, on
request of such successor Collateral Trustee, be so executed, acknowledged and
delivered.

          (d) Any required filing for record of the instrument appointing a
successor Collateral Trustee as hereinabove provided shall be at the expense of
the Grantors. The resignation of any Collateral Trustee and the instrument or
instruments removing any Collateral Trustee, together with all other
instruments, deeds and conveyances provided for in this Agreement shall, if
required by law, be forthwith recorded, registered and filed by and at the
expense of the Grantors, wherever this Agreement is recorded, registered and
filed.

          Section 6.8 Status of Successors to the Collateral Trustee. Every
successor to the Collateral Trustee appointed pursuant to Section 6.7 of this
Agreement and every corporation resulting from a merger or consolidation
referred to in Section 6.9 of this Agreement shall be a bank or trust company in
good standing and having power so to act, incorporated under the laws of the
United States or any state thereof or the District of Columbia, and having its
principal corporate trust office within the forty-eight (48) contiguous States,
and shall also have capital, surplus and undivided profits of not less than
$100,000,000.

          Section 6.9 Merger of the Collateral Trustee. Any corporation into
which the Collateral Trustee shall be merged, or with which it shall be
consolidated, or any corporation resulting from any merger or consolidation to
which the Collateral Trustee shall be a party, shall be the Collateral Trustee
under this Agreement without the execution or filing of any paper or any further
act on the part of the parties hereto.

          Section 6.10 Additional Co-Trustees; Separate Trustees.

          (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 Shared Collateral
shall be located, or the Collateral Trustee shall be advised by counsel
satisfactory to it that it is so necessary or prudent in the interest of the
Secured Parties, or the Bank Administrative Agent shall in writing so request,
or the Collateral Trustee shall deem it desirable for its own protection in the
performance of its duties hereunder, then the Collateral Trustee and the
Grantors 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 Collateral Trustee and the Grantors either to act as co-trustee
or co-trustees of all or any of the Shared Collateral, jointly with the
Collateral

                                       24

<PAGE>

Trustee originally named herein or any successor or successors, or to
act as separate trustee or trustees of any such property. Notwithstanding the
foregoing sentence, the Collateral Trustee shall not be responsible for
ascertaining whether or not it is at any time necessary or prudent to constitute
another bank or trust company or any other Person(s) to act as co-trustee or a
separate trustee. In the event the Grantors shall not have joined in the
execution of such instruments and agreements within ten (10) days after the
receipt of a written request from the Collateral Trustee so to do, or in case a
Notice of Actionable Default shall have been given and not withdrawn, the
Collateral Trustee may act under the foregoing provisions of this Section 6.10
without the concurrence of the Grantors and each Grantor hereby irrevocably
appoints the Collateral Trustee as its agent and attorney to act for it under
the foregoing provisions of this Section 6.10 in either of such contingencies.

          (b) Every separate trustee and every co-trustee, other than any
trustee which may be appointed as successor to Citibank, N.A., as Collateral
Trustee, shall, to the extent permitted by law, be appointed and act and be
such, subject to the following provisions and conditions, namely:

          (i) all rights, powers, duties and obligations conferred upon the
     Collateral Trustee in respect of the custody, control and management of
     moneys, papers or securities shall be exercised solely by Citibank, N.A, as
     Collateral Trustee, or its successors as the Collateral Trustee hereunder,

          (ii) all rights, powers, duties and obligations conferred or imposed
     upon the Collateral Trustee hereunder shall be conferred or imposed and
     exercised or performed by the Collateral Trustee and 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 Collateral Trustee shall be incompetent or
     unqualified to perform such 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 (i) given hereby to any co-trustee, co-trustees or
     separate trustees, or (ii) which is provided hereby to any co-trustee,
     co-trustees or separate trustees, may be exercised by any such co-trustee
     or co-trustees or separate trustees, except jointly with, or with the
     consent in writing of, the Collateral Trustee, anything herein contained in
     the contrary notwithstanding;

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

          (v) the Grantors and the Collateral Trustee, at any time by an
     instrument in writing, executed by them jointly, may accept the resignation
     of or remove any such separate trustee or co-trustee, and in that case, by
     an instrument in writing executed by the Grantors and the Collateral
     Trustee jointly, may appoint a successor to such separate trustee or
     co-trustee, as the case may be, anything herein contained to the contrary
     notwithstanding. In the event that the Grantors shall not have joined in
     the execution of any such instrument within ten (10) days after the receipt
     of a written request from the Collateral Trustee so to do, or in case a
     Notice of Actionable Default shall have been given and not withdrawn, the
     Collateral 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 Grantors, each of the Grantors hereby

                                       25

<PAGE>

     irrevocably appointing the Collateral Trustee, its agent and attorney to
     act for it in such connection in either of such contingencies. In the event
     that the Collateral Trustee shall have appointed a separate trustee or
     separate trustees or co-trustee or co-trustees as above provided, it may at
     any time, by an instrument in writing, accept the resignation of or remove
     any such separate trustee or co-trustee, the successor to any such separate
     trustee or co-trustee to be appointed by the Grantors and the Collateral
     Trustee, or by the Collateral Trustee alone, as hereinabove provided in
     this Section 6.10.

          Section 6.11 Assignment of Rights, Not Assumption of Duties.

          Anything herein contained to the contrary notwithstanding, (a) the
Grantors shall remain liable under each of the other Shared Collateral Documents
to which they are a party to the extent set forth therein to perform all of
their duties and obligations thereunder to the same extent as if this Agreement
had not been executed, (b) the exercise by the Collateral Trustee of any of its
rights, remedies or powers hereunder shall not release the Grantors from any of
their duties or obligations under each of the other Shared Collateral Documents
to which they are a party and (c) the Collateral Trustee shall not have any
obligation or liability under any of the other Shared Collateral Documents to
which the Grantors are a party by reason of or arising out of this Agreement.

          Section 6.12 No Liability.

          Anything in this Agreement to the contrary notwithstanding, in no
event shall the Collateral Trustee be liable under or in connection with this
Agreement for indirect, special, incidental, punitive or consequential losses or
damages of any kind whatsoever, including but not limited to lost profits,
whether or not foreseeable, even if the Collateral Trustee has been advised of
the possibility thereof and regardless of the form of action in which such
damages are sought.

          ARTICLE VII. RELEASE OF COLLATERAL

          Section 7.1 Conditions to Release

          (a) So long as no Actionable Default has occurred and is continuing,
all of the Shared Collateral shall be released upon the receipt by the
Collateral Trustee from the Bank Administrative Agent of (A) a written direction
to cause the liens on the Shared Collateral to be released and discharged, or
(B) written notice stating that the Credit Agreement and the L/C Agreement have
terminated in accordance with the terms thereof, and there has been payment in
full of all Senior Secured Obligations thereunder and all accrued and unpaid
Collateral Trustee Fees; provided, that if any amounts are then due and payable
under the Astaris Agreement as communicated to the Collateral Trustee by the
Bank Administrative Agent, the written consent of the majority in interest of
the Astaris Lenders shall also be required to release all or substantially all
of the Shared Collateral. Upon release of the Shared Collateral in accordance
with this Section 7.1(a), the security interests created by the Shared
Collateral Documents shall terminate forthwith and all right, title and interest
of the Collateral Trustee in and to the Shared Collateral shall revert to the
Grantors and their successors and assigns; provided, however, that if (but only
if) an Actionable Default based on an Indenture Event of Default exists on the
date of such release and such date is also the Credit Agreement Termination
Date, any proceeds of any Shared Collateral sold or otherwise disposed of on
such date and not used to repay in full the Senior Secured Obligations shall
remain subject to the pledge hereunder (and continue to constitute Shared
Collateral) until such Actionable Default shall have been cured or otherwise
waived by the

                                       26

<PAGE>

Requisite Obligees (determined after giving effect to the Credit Agreement
Termination Date), at which time any continuing right or interest in such Shared
Collateral shall terminate.

          (b) So long as no Actionable Default has occurred and is continuing,
any portion of the Shared Collateral shall be released upon the receipt by the
Collateral Trustee from the Bank Administrative Agent of written directions
instructing the Collateral Trustee to release any portion of the Shared
Collateral (the "Released Collateral"); provided, that if any amounts are then
due and payable under the Astaris Agreement as communicated to the Collateral
Trustee by the Bank Administrative Agent, the written consent of the majority in
interest of the Astaris Lenders shall also be required to release any part of
the Shared Collateral. Upon the partial release of the Shared Collateral in
accordance with this Section 7.1(b), the security interests created by the
Shared Collateral Documents in the Released Collateral shall terminate forthwith
and all right, title and interest of the Collateral Trustee in and to the
Released Collateral shall revert to the Grantors and their successors and
assigns.

          (c) Upon the termination of the Collateral Trustee's security interest
and the release of the Shared Collateral in accordance with Section 7.1(a) or
the Released Collateral in accordance with Section 7.1(b), the Collateral
Trustee will promptly, at FMC's written request and expense, (i) execute and
deliver to FMC such documents as FMC shall reasonably request to evidence the
termination of such security interest or the release of the Shared Collateral or
the Released Collateral, as the case may be and (ii) deliver or cause to be
delivered to the Grantors all property of the Grantors or the Released
Collateral, as the case may be, then held by the Collateral Trustee or any agent
thereof.

          (d) Notwithstanding anything to the contrary contained herein, the
Collateral Trustee shall take any action, including the release of all or any
portion of the Shared Collateral, required pursuant to Section 2.3.

          Section 7.2 Effective Time of Release.

          (a) The release of Shared Collateral shall be effective upon the
receipt by the Collateral Trustee of written confirmation from the Bank
Administrative Agent. The Collateral Trustee shall promptly notify the Grantors
and the Secured Parties, in the manner specified in Section 8.2 of this
Agreement, when the release of the Shared Collateral is effective.

          (b) When the release of all of the Shared Collateral is effective, all
right, title and interest of the Collateral Trustee in, to and under the Trust
Estate shall terminate and shall revert to the Grantors or their respective
successors and assigns, and the estate, right, title and interest of the
Collateral Trustee therein shall thereupon cease, terminate and become void
except with respect to those provisions of this Agreement that expressly
survive. In such case, each Grantor at its sole cost and expense shall deliver
to the Collateral Trustee one or more instruments of discharge, satisfaction and
release in form reasonably satisfactory to the Collateral Trustee, and, upon the
written request of a Grantor or its successors or assigns, and at the cost and
expense of such Grantor or its successors or assigns, the Collateral Trustee
shall execute a satisfaction of the Shared Collateral Documents and such
instruments as the Grantors may request to terminate and remove of record any
documents constituting public notice of the Shared Collateral Documents and the
Liens and assignments granted thereunder and shall assign and transfer, or cause
to be assigned and transferred, and shall deliver or cause to be delivered to
the Grantors, all property, including all moneys, instruments and securities of
the Grantors, then held by the Collateral Trustee. The cancellation and
satisfaction of the Shared Collateral Documents shall be without prejudice to
the rights of the Collateral Trustee or any successor Collateral Trustee to

                                       27

<PAGE>

charge and be reimbursed for any expenditures which it may thereafter incur in
connection therewith.

Secured Debt.

          (d) All such amendments, supplemental agreements, modifications and
waivers shall be in writing and executed by the parties required to consent

shall be effective only in the specific instance and for the specific purpose
for which made or given.

          (e) Notwithstanding anything in this Agreement to the contrary, no
