      this Trust Agreement and in the Guarantees and the Security Documents in
      accordance with the direction of the Required Secured Parties as provided
      herein. The Trustees are not empowered to exercise any remedy hereunder or
      thereunder relating to the foreclosure of Collateral or enforcement of any
      Guarantee unless a Notice of Enforcement is in effect; PROVIDED that for
      the avoidance of doubt, this subsection 2.1(a) shall in no event limit the

      believes that all actions theretofore taken by the Trustees to exercise
      any remedy or remedies with respect to the Collateral or the Guarantees
      can be reversed without undue difficulty. The Corporate Trustee shall
      immediately notify the Borrower as to the receipt of any such Notice of

any officer or agent thereof, with full power of substitution, as its true and
lawful attorneys-in-fact with full power and authority in the name of the
Borrower or in its or his own name, from time to time in the Trustees'
discretion, so long as any Notice of Enforcement is in effect, to take any and
all appropriate action and to execute any and all documents and instruments
which may be necessary or desirable to carry out the terms of this Trust
Agreement, the Guarantees and the Security Documents and accomplish the purposes
hereof and thereof, and, without limiting the generality of the foregoing, the
Borrower hereby gives the Trustees the power and right on behalf of the
Borrower, without notice to or further assent by the Borrower, to do the
following so long as a Notice of Enforcement is in effect (and, in the case of
clause (e) (i) below, whether or not a Notice of Enforcement is in effect):

            (a) to ask for, demand, sue for, collect, receive and give

      or in connection with the Guarantees or any Security Document;

            (c) to commence, prosecute, defend, settle, compromise or adjust any

      against the Borrower, the Trustees or any Secured Party;

            (d) to sell, transfer, assign or otherwise deal in or with the

      If a Notice of Enforcement is in effect, upon the filing of a bill in
equity or other commencement of judicial proceedings to enforce the rights of
the Trustees under this Trust Agreement, any Guarantee or any Security Document,
the Trustees shall, to the extent permitted by applicable law, without notice to
the Borrower or any party claiming through the Borrower, without regard to the
solvency or insolvency at the time of any Person then liable for the payment or
performance of any of the 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 (who may be a Trustee) 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 Trustees and the Secured
Parties, and the Borrower irrevocably consents to the appointment of such
receiver or receivers and to the entry of such order; PROVIDED that

      forth in any Guarantee or any Security Document may be exercised from time
      to time as herein and therein provided.

      of subsection 2.1(a)) have the right, by one or more instruments in
      writing executed and delivered to the Corporate Trustee, to direct the
      time, method and place of conducting any proceeding for any right or
      remedy available to the Trustees, or of exercising any trust or power
      conferred on the Trustees, 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, any Guarantee or any Security Document, and the
      Trustees shall act in accordance with any such direction; PROVIDED that
      such direction shall not conflict with any provision of applicable law or
      of this Trust Agreement, any Guarantee or any Security Document and the
      Trustees shall be adequately secured and indemnified as provided in
      subsection


                                       10

      from the Required Secured Parties shall not be required to) take any and
      all such actions under this Trust Agreement, the Security Documents and
      the Guarantees or any of them or otherwise as the Corporate Trustee shall
      deem to be in the best interests of the Secured Parties to maintain the
      Collateral and protect and preserve the Collateral and the rights of the
      Secured Parties; PROVIDED, HOWEVER, that in the absence of direction
      (which may relate to the exercise of specific remedies or to the exercise
      of remedies in general) from the Required Secured Parties while a Notice
      of Enforcement is in effect, the Trustees shall not foreclose any Lien on
      the Collateral or take any enforcement action under any Guarantee.

      2.6   REMEDIES NOT EXCLUSIVE.

            (a) No remedy conferred upon or reserved to the Trustees herein or
      in any Guarantee or Security Document 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, in any
      Guarantee or in any Security Document or now or hereafter existing at law
      or in equity or by statute.

            (b) No delay by the Trustees in exercising or failure by the
      Trustees to exercise any right, remedy or power hereunder or under any
      Guarantee or 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 to the Trustees under this Trust Agreement, any Guarantee
      or any Security Document may be exercised from time to time and as often
      as may be deemed expedient by the Trustees or the Required Secured
      Parties.

            (c) If the Trustees shall have proceeded to enforce any right,
      remedy or power under this Trust Agreement, any Guarantee or any 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 Trustees, then the Borrower, the Trustees 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 Trustees
      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, the Guarantees and the Security Documents may be enforced
      by the Trustees without the possession of any Secured Instrument,
      Guarantee, Security Document or instrument evidencing any Obligation or
      the production thereof at any trial or other proceeding relative thereto,
      and any suit or proceeding instituted by the Trustees shall be, subject to
      subsections 7.5(c), 7.5(d) and 7.10(b)(ii), brought in their name as
      Trustees and any recovery of judgment shall be held as part of the Trust
      Estate.

      Agreement;

            FIFTH: to the Hedging Agreement Secured Parties in an amount equal

            SIXTH: any surplus then remaining shall be paid to the Borrower or
      its successors or assigns or to whomsoever may be lawfully entitled to
      receive the same or as a court of competent jurisdiction may direct.

            (b)   The term "unpaid" as used in subsection 3.4(a) refers:

                  (i)   in  the  absence  of  a  bankruptcy   proceeding  with
            respect  to the  Borrower,  to all  amounts  payable in respect of
            Obligations outstanding as of a Distribution Date, and

                  (ii) during the pendency of a bankruptcy proceeding with
            respect to the Borrower, to all amounts allowed by the bankruptcy
            court in respect of the Obligations 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 subsection 3.5) have not been made in respect
      thereof.

            (c) The Corporate Trustee shall make all payments and distributions
      under this subsection 3.4: (i) on account of the Credit Facility to the
      Administrative Agent for redistribution or application in accordance with
      the provisions of the Credit Agreement and (ii) on account of any Hedging
      Agreement Obligations, directly to the Holder of such Hedging Agreement
      Obligations.

      3.5   AMOUNTS HELD FOR CONTINGENT OBLIGATIONS.

      In the event the Administrative Agent or any Holder shall receive any
moneys pursuant to subsection 3.4 in respect of the contingent portion of the
outstanding Obligations, then the Administrative Agent or such Holder, as the
case may be, shall invest such moneys in obligations of the kinds referred to in
clauses (a) and (b) of subsection 3.3 maturing within 90 days after they are
acquired by the Administrative Agent or such Holder and shall hold all such


                                       16
<PAGE>

amounts so distributable, and all such investments and the net proceeds thereof,
in trust until (i) all or part of such contingent claim shall have become fixed,
in which case the Administrative Agent or such Holder, as the case may be, shall
apply to the payment of such fixed claim from such investments and the proceeds
thereof an amount equal to such fixed claim, and shall promptly give notice
thereof to the Borrower and the Corporate Trustee or (ii) all or part of such
contingent claim shall have been extinguished, whether as the result of an
expiration without drawing of any letter of credit, payment of amounts secured
or covered by any letter of credit other than by drawing thereunder, payment of
amounts covered by any guarantee or otherwise, in which case the Administrative
Agent or such Holder, as the case may be, shall, as soon as practicable
thereafter, notify the Borrower and the Corporate Trustee and shall distribute
from such investments, and the proceeds thereof, an amount equal to the portion
of the contingent claim which has been extinguished together with interest
earned thereon from the date first invested until so distributed, to the
Corporate Trustee for deposit in the Collateral Account and application in
accordance with the provisions of subsection 3.4.

      3.6   APPLICATION OF MONEYS  DISTRIBUTABLE TO THE  ADMINISTRATIVE
AGENT.

      If at any time any moneys collected or received by the Trustees pursuant
hereto are distributable pursuant to subsection 3.4 to the Administrative Agent,
and if the Administrative Agent shall notify the Corporate Trustee in writing
that no provision is made under the Credit Agreement for the application by the
Administrative Agent of moneys (whether because the Payment Obligations issued
under the Credit Agreement have not become due and payable or otherwise) and
that the Credit Agreement does not effectively provide for the receipt and the
holding by the Administrative Agent of such moneys pending the application
thereof, then the Corporate Trustee, after receipt of such notification, shall
invest such amounts at the written direction of the Administrative Agent in
obligations of the kinds referred to in clauses (a) and (b) of subsection 3.3
maturing within 90 days after they are acquired by the Corporate Trustee and
shall hold all such amounts so distributable and all such investments and the
net proceeds thereof in trust solely for the Administrative Agent (in its
capacity as such) and for no other purpose until such time as the Administrative
Agent shall request in writing the delivery thereof by the Corporate Trustee for
application pursuant to the Credit Agreement.

      3.7   TRUSTEES' CALCULATIONS.

      In making the determinations and allocations required by subsection 3.4,
the Corporate Trustee may, unless a Responsible Trustee Officer has actual
knowledge to the contrary, rely upon a certificate executed and supplied by the
Administrative Agent or (in the case of Hedging Agreement Obligations) the
Holders, as the case may be, as to the amounts payable with respect to Payment
Obligations, all in accordance with subsection 7.2(b), and the Trustees shall
have no liability to any of the Secured Parties for actions taken in reliance on
such information; PROVIDED, HOWEVER, that if any Secured Party receives on any
Distribution Date an amount pursuant to subsection 3.4(a) in excess of the
amount to which it was entitled to receive on such Distribution Date pursuant to
such subsection 3.4(a) as a result of any such certificate overstating the
amount of the Payment Obligations held by such Secured Party (or, with respect
to the Credit Facility, the Payment Obligations held by all the Secured Parties
under the Credit Facility), then such Secured Party (by becoming a Holder of
Obligations and accepting the benefits of this Trust


                                       17
<PAGE>

Agreement) shall pay such excess to the Corporate Trustee for application in
accordance with subsection 3.4(a) as soon as practicable after the existence of
such overstatement shall have been determined. All distributions made by the
Corporate Trustee pursuant to subsection 3.4 shall be (subject to any decree of
any court of competent jurisdiction and to the proviso in the preceding
sentence) final, and the Trustees shall have no duty to inquire as to the
application by any Holder or the Administrative Agent of any amounts distributed
to them. By accepting the benefits of this Agreement, the Security Documents and
the Guarantees, each Secured Party and the Administrative Agent agrees to act in
accordance with this Trust Agreement and not take any action inconsistent
herewith.

would be in contravention of any Secured Instrument in connection with the
Credit Facility (including, without limitation, the Credit Agreement), and any
purported designation of any such indebtedness or other obligations of the
Borrower as in violation of any Secured Instrument in connection with the Credit
Facility shall be null and void and of no force or effect.

of the Borrower under this subsection shall survive the termination of the other
provisions of this Trust Agreement and the resignation or removal of the
Trustees.

      5.6   INDEMNIFICATION.

      The Borrower agrees to pay, indemnify, and hold the Trustees harmless from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses (including, without limitation, the
reasonable fees of counsel) or disbursements of any kind or nature whatsoever
with respect to the execution, delivery, enforcement, performance and
administration of this Trust Agreement, the Guarantees and the Security
Documents, unless arising from the gross negligence or willful misconduct of the
indemnified party, including, without limitation, indemnification of the
respective Trustees for liabilities of the respective Trustees for the net
amount of taxes (after taking account of any deduction, credit or other tax
reduction or benefit available by reason of the imposition of any such tax) in
any jurisdiction in which the respective Trustees would not otherwise be subject
to tax except by reason of their acting under this Trust Agreement, any
Guarantee or any Security Document (directly or through agents, separate
trustees or co-trustees), PROVIDED that such indemnification for taxes (a) shall
apply only (i) in respect of taxes attributable to the performance of the
respective Trustees' obligations as Trustee hereunder or under any Guarantee or
Security Document and (ii) to the extent that the respective Trustees, using
reasonable efforts, shall have been unable to avoid or minimize the same as
contemplated by subsection 7.10 and (b) shall in no event cover any taxes
imposed upon the respective Trustees with respect to or measured by their net
income or profits. In any suit, proceeding or action brought by the Trustees
under or with respect to any contract, agreement, interest or obligation
constituting part of the Collateral for any sum owing thereunder, or to enforce
any provisions thereof, the Borrower will save, indemnify and keep the Trustees
harmless from and against all expense, loss or damage suffered by reason of any
defense, setoff, counterclaim, recoupment or reduction of liability whatsoever
of the obligor thereunder, arising out of a breach by the Borrower of any
obligation thereunder or arising out of any other agreement, indebtedness or
liability at any time owing to or in favor of such obligor or its successors
from the Borrower, and all such obligations of the Borrower shall be and remain
enforceable against and only against the Borrower and shall not be enforceable
against the Trustees. The agreements in this subsection shall survive the
termination of the other provisions of this Trust Agreement and the resignation
or removal of the Trustees.

      5.7   TRUSTEES' LIEN.

      Notwithstanding anything to the contrary in this Trust Agreement, as
security for the payment of Trustee Fees (i) the Trustees are hereby granted a
first priority Lien upon all Collateral and (ii) the Trustees shall have the
right to use and apply any of the funds held by the Corporate Trustee in the
Collateral Account to cover such Trustee Fees.

      5.8   FURTHER ASSURANCES.

      At any time and from time to time, whether or not a Notice of Enforcement
shall be in effect, upon the written request of the Corporate Trustee (which
shall be made only upon the written direction of the Required Secured Parties),
and at the expense of the Borrower, the Borrower will promptly execute and
deliver any and all such further instruments and documents and take such further
action as the Corporate Trustee has been so directed is necessary or reasonably
requested to obtain the full benefits of this Trust Agreement and the Security


                                       25
<PAGE>

Documents and of the rights and powers herein and therein granted or to cause
any assets required under a Secured Instrument to be subject to a perfected
security interest of the Trustees to be so subject, including, without
limitation, the filing of any financing or continuation statements under the
Uniform Commercial Code in effect in any jurisdiction with respect to the Liens
and security interests granted under the Security Documents. The Borrower also
hereby authorizes the Corporate Trustee to sign and to file any such documents,
instruments or financing or continuation statements without the signature of the
Borrower to the extent permitted by applicable law, but in no way is the
Corporate Trustee obligated to do so.

                               SECTION 6

           POSSESSION AND USE OF COLLATERAL; PARTIAL RELEASES

      6.1   USE PRIOR TO NOTICE OF ENFORCEMENT.

      So long as no Notice of Enforcement is in effect, the Borrower shall have
the right (subject to compliance with subsection 6.1(b)): (i) to remain in
possession and retain exclusive control of the Collateral (except any Possessory
Collateral) with power freely and without hindrance on the part of the Trustees
or the Secured Parties to operate, manage, develop, use and enjoy the Collateral
and to receive the rents, issues, tolls, profits, royalties, revenues and other
income thereof, and (ii) to sell or otherwise dispose of, free and clear of the
Lien and security interest created by subsection 5.7 and by the Security
Documents, any Collateral if such sale or other disposition is not prohibited by
the terms of the Credit Agreement and the Security Document and so long as the
proceeds (in the percentage required) from such sale are applied to the Facility
Obligations in accordance with Section 2.09 of the Credit Agreement. The
Trustees shall have no duty to monitor the exercise by the Borrower of its
rights under this subsection.

      6.2   RELEASES; SUBORDINATION.

            (a) Asset Sales in respect of Collateral which are permitted by
      Section 6.1 shall not require any written or oral release or consent of
      the Trustees. Nevertheless, the Borrower may, upon the delivery to the
      Corporate Trustee and the Administrative Agent of a certificate of a
      Responsible Officer, together with such other evidence as the Corporate
      Trustee shall reasonably require, to the effect that such sale, transfer
      or disposition is in compliance with the requirements of such subsection
      6.1, that the proceeds (in the percentage required) of such transaction
      have been or will be applied to the Facility Obligations as set forth in
      Section 2.09 of the Credit Agreement and that subsection 6.2(b) has been
      complied with in full, request that the Trustees execute and deliver to
      the Borrower or any purchaser of Collateral a written release, disclaimer
      or quitclaim of the Trustees' interest in any Collateral under subsection
      5.7 and under the Security Documents, and such purchaser shall be entitled
      to rely conclusively on such release, disclaimer or quitclaim. Such
      request shall be in writing, shall describe the property to be released in
      reasonable detail, and shall state that such release is or will be in
      accordance with the terms of the Credit Agreement and the Security
      Documents and shall be accompanied by a written certificate of a
      Responsible Officer of the Borrower directing the Trustees to execute and
      deliver such release, disclaimer or quitclaim.


                                       26
<PAGE>

            (b) If it is a condition of the release of any Collateral from the
      security interest under subsection 5.7 or under any Security Document or
      Secured Instrument that the Trustees be granted a first priority Lien or
      security interest in additional property to be held as Collateral pursuant
      to this Trust Agreement, then the Trustees shall be granted such Lien or
      security interest prior to or concurrently with the delivery to the
      Borrower of any such Collateral or any release, disclaimer or quitclaim in
      connection therewith. The grant of such Lien or security interest shall be
      effected by (i) delivery to the Corporate Trustee of an Additional
      Collateral Designation pursuant to subsection 4.4 and (ii) fulfilling the
      requirements of subsection 4.9(b) with respect thereto.

            (c) If any Collateral which is being sold or otherwise disposed of
      pursuant to this Section 6 is in the possession of the Trustees or any
      agent or nominee thereof, the Trustees or such agent or nominee shall upon
      the delivery to the Corporate Trustee and the Administrative Agent of a
      certificate of a Responsible Officer, together with such other evidence as
      the Corporate Trustee shall reasonably require, to the effect that such
      sale, transfer or disposition is in compliance with the requirements of
      such subsection 6.1, that the proceeds of such transaction have been or
      will be applied as set forth in the relevant provisions, if any, of each
      Secured Instrument and that subsection 6.2(b) has been complied with in
      full, release such Collateral to the Borrower in connection with such
      Asset Sale.

            (d) Purchase money Liens which are permitted by Section 6.02(iv) of
      the Credit Agreement (each a "Permitted Purchase Money Lien") shall not
      require any written or oral subordination agreement or release or consent
      of the Trustees. Nevertheless, the Borrower may, upon the delivery to the
      Corporate Trustee and the Administrative Agent of a certificate of a
      Responsible Officer, together with such other evidence as the Corporate
      Trustee or the Administrative Agent shall reasonably require, to the
      effect that such Permitted Purchase Money Lien is in compliance with the
      requirements of Section 6.02(iv) of the Credit Agreement, request that the
      Trustees execute and deliver to the Borrower or any beneficiary of such
      Permitted Purchase Money Lien a written Lien subordination agreement
      stating that the Trustees' Liens are and shall be subject and subordinate
      in all respects and in all contingencies to such Permitted Purchase Money
      Lien with respect to the Collateral or other property subject to such
      Permitted Purchase Money Lien and the proceeds thereof, and such
      beneficiary shall be entitled to rely conclusively on such subordination
      agreement. In the alternative, it is further agreed that the Borrower may,
      by the submission to the Administrative Agent of a certificate of a
      Responsible Officer in accordance with the requirements of Section
      6.02(iv) of the Credit Agreement, request that the Trustees execute and
      deliver to the Borrower or any beneficiary of such Permitted Purchase
      Money Lien a written U.C.C.-3 termination statement or other necessary
      evidence of termination releasing the Trustees' Liens with respect to the
      Collateral or other property subject to such Permitted Purchase Money Lien
      and the proceeds thereof. Each of such requests shall be in writing, shall
      describe the property subject to such Permitted Purchase Money Lien, in
      reasonable detail, and shall state that such subordination agreement or
      Lien termination, as applicable, is or will be in accordance with the
      terms of the Credit Agreement and the Security Documents and shall be
      accompanied by a written certificate of a Responsible


                                       27
<PAGE>

      Officer of the Borrower directing the Trustees to execute and deliver such
      subordination agreement or evidence of Lien termination, as appropriate.

            (e) The notices, statements, directions, evidence and certificates
      requested under or required by this subsection (together with any required
      certificate of a Responsible Officer under subsection 7.4(e)) shall be
      full authority for and direction to the Trustees to execute and deliver
      the releases, disclaimers, quitclaims, subordination agreements and other
      instruments referred to in this subsection, and the Trustees shall
      promptly do so, subject to the terms of this subsection 6.2, upon a
      request therefor. The Trustees in so doing shall have no liability to any
      Person other than for its willful misconduct or gross negligence.

      6.3   INSURANCE AND CONDEMNATION PROCEEDS; LIQUIDATING DIVIDENDS.

      Any insurance proceeds, any Proceeds from the exercise of rights of
eminent domain or condemnation and any liquidating dividends paid in respect of
Pledged Equity Securities received by the Borrower or the Trustees in respect of
Collateral shall be treated as cash Proceeds received pursuant to subsection
6.1(b) and shall, if a Notice of Enforcement is in effect, be deposited in the
Collateral Account, and if no Notice of Enforcement is in effect, such amounts
shall be delivered to the Borrower unless otherwise required by any Secured
Instrument.

      6.4   PURCHASE OF COLLATERAL.

      Any Secured Party may purchase Collateral at any public sale of such
Collateral pursuant to any of the Security Documents and, with the consent of
the Required Secured Parties and if permitted by the Secured Instrument
governing such Payment Obligation, may make payment on account of such purchase
by using any Payment Obligation then due and payable to such Secured Party as a
credit (up to the amount of such Payment Obligation) against the purchase price;
PROVIDED that in determining the Required Secured Parties for purposes of this
subsection, all Voting Obligations held by such purchasing Secured Party shall
be excluded.

                               SECTION 7

                              THE TRUSTEES

      7.1   ACCEPTANCE OF TRUST.

      The Trustees, for themselves and their respective successors, hereby
accept the trusts created by this Trust Agreement upon the terms and conditions
hereof.

      7.2   EXCULPATORY PROVISIONS.

            (a) The Trustees shall not be responsible in any manner whatsoever
      for the correctness of any recitals, statements, representations or
      warranties herein, all of which are made solely by the Borrower. The
      Trustees make no representations as to the value or condition of the Trust
      Estate or any part thereof, or as to the title of the Borrower thereto or
      as to the security afforded by this Trust Agreement or any Security
      Document, or as to the validity, execution (except their own execution),
      enforceability, legality or sufficiency


                                       28
<PAGE>

      of this Trust Agreement, Guarantee, any Security Document or Obligation,
      and the Trustees shall incur no liability or responsibility in respect of
      any such matters. The Trustees shall not be responsible for insuring the
      Collateral or for the payment of taxes, charges or assessments or
      discharging of Liens upon the Collateral or otherwise as to the
      maintenance of the Collateral, except that if the Trustees take possession
      of any Collateral, the Trustees shall use the same care in the
      preservation of the Collateral in their possession as they would use for
      their own property.

            (b) The Trustees shall not be required to ascertain or inquire as to
      the performance by the Borrower or any of its Subsidiaries of any of the
      covenants or agreements contained herein or in any Security Document, any
      Guarantee or any Secured Instrument. Whenever it is necessary, or in the
      opinion of the Trustees advisable, for the Trustees to ascertain the
      amount or nature of Obligations then held by Secured Parties, the Trustees
      may rely, absent actual knowledge of a Responsible Trustee Officer to the
      contrary, on a certificate of the Administrative Agent or any Holder of
      Hedging Agreement Obligations, as the case may be, and, if the
      Administrative Agent or such Holder of Hedging Agreement Obligations shall
      not give such information to the Corporate Trustee, it shall not be
      entitled to receive distributions hereunder (in which case distributions
      to those Persons who have supplied such information to the Corporate
      Trustee shall be calculated by the Corporate Trustee using, for those
      Persons who have not supplied such information, the list then most
      recently delivered by the Borrower pursuant to subsection 5.2), and the
      amount so calculated to be distributed to the Person who fails to give
      such information shall be held in trust for such Person until such Person
      does supply such information to the Corporate Trustee, whereupon on the
      next Distribution Date the amount distributable to such Person shall be
      recalculated using such information and distributed to it.

            (c) The Trustees shall be under no obligation or duty to take any
      action under this Trust Agreement, any Guarantee or any Security Document
      if taking such action (i) would subject the Trustees to a tax in any
      jurisdiction where they are not then subject to a tax or (ii) would
      require the Corporate Trustee to qualify to do business in any
      jurisdiction where it is not then so qualified, unless the Trustees
      receive security or indemnity satisfactory to them 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, any Guarantee or any Security Document.

            (d) Notwithstanding any other provision of this Trust Agreement,
      neither the Corporate Trustee nor the Individual Trustee, in its or his
      individual capacity, shall be personally liable for any action taken or
      omitted to be taken by it or him in accordance with this Trust Agreement,
      any Guarantee or any Security Document except for its or his own gross
      negligence or willful misconduct.

            (e) The Corporate Trustee shall have the same rights with respect to
      any Obligation held by it as any other Secured Party and may exercise such
      rights as though it were not the Corporate Trustee hereunder, and may
      accept deposits from, lend money to,


                                       29
<PAGE>

      and generally engage in any kind of banking or trust business with the
      Borrower and its affiliates as if it were not the Corporate Trustee.

      7.3   DELEGATION OF DUTIES.

      The Trustees 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 Trustees shall be entitled to advice of counsel concerning all matters
pertaining to such trusts, powers and duties. The Trustees shall not be
responsible for the negligence or misconduct of any agents or attorneys-in-fact
selected by them with reasonable care.

      7.4   RELIANCE BY TRUSTEES.

            (a) Whenever in the administration of this Trust Agreement, the
      Guarantees or the Security Documents the Trustees shall deem it necessary
      or desirable that a factual matter be proved or established in connection
      with the Trustees taking, suffering or omitting any action hereunder or
      thereunder, such matter (unless other evidence in respect thereof is
      herein specifically prescribed) may be deemed in the absence of actual
      knowledge of a Responsible Trustee Officer to the contrary to be
      conclusively proved or established by a certificate of a Responsible
      Officer delivered to the Corporate Trustee, and such certificate shall be
      full warrant to the Trustees for any action taken, suffered or omitted in
      reliance thereon, subject, however, to the provisions of subsection 7.5.

            (b) The Trustees 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 them hereunder or under any Guarantee
      or Security Document in accordance therewith. The Trustees shall have the
      right at any time to seek instructions concerning the administration of
      this Trust Agreement, the Guarantees and the Security Documents from any
      court of competent jurisdiction.

            (c) The Trustees 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
      they in good faith believe to be 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 their gross negligence or willful misconduct, the
      Trustees 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 Trustees and conforming to the requirements of
      this Trust Agreement.

            (d) The Trustees shall not be under any obligation to exercise any
      of the rights or powers vested in the Trustees by this Trust Agreement,
      the Guarantees and the Security Documents, at the request or direction of
      the Required Secured Parties pursuant to this Trust Agreement or
      otherwise, unless the Trustees shall have been provided adequate security
      and indemnity against the costs, expenses and liabilities which may be


                                       30
<PAGE>

      incurred by them in compliance with such request or direction, including
      such reasonable advances as may be requested by the Trustees.

            (e) Upon any application or demand by the Borrower (except any such
      application or demand which is expressly permitted to be made orally) to
      the Trustees to take or permit any action under any of the provisions of
      this Trust Agreement, any Guarantee or any Security Document, the Borrower
      shall furnish to the Corporate Trustee a certificate of a Responsible
      Officer stating that all conditions precedent, if any, provided for in
      this Trust Agreement, in any relevant Guarantee, Security Document or
      Secured Instrument 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, any Guarantee or any Security Document relating to
      such particular application or demand, such additional document shall also
      be furnished.

      7.5   LIMITATIONS  ON DUTIES  OF  TRUSTEES;  RELATIONSHIP  BETWEEN
CORPORATE TRUSTEE AND INDIVIDUAL TRUSTEE.

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

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

            (c) The Individual Trustee has been joined as such so that if, by
      any present or future law in any jurisdiction in which it may be necessary
      to perform any act in the execution of the trust hereby created, the
      Corporate Trustee, or its successor or successors, may be incompetent or
      unqualified to act as such Trustee, or would be subject to a tax that
      would not otherwise be imposed except for such act, then all the acts
      required to be performed in such jurisdiction in the execution of the
      trusts hereby created, shall and will be performed by the Individual
      Trustee, or his successor or successors, acting alone. Except as it may be
      deemed necessary for the Individual Trustee solely or jointly with the
      Corporate Trustee to execute the trusts hereby created, the Corporate


                                       31
<PAGE>

      Trustee, notwithstanding any other provision of this Trust Agreement, any
      Guarantee or any Security Document to the contrary, shall solely have and
      exercise the powers, and shall be solely charged with the performance of
      the duties, of the Trustees provided for herein, in any Guarantee or any
      Security Document.

            (d) No provision of this Trust Agreement, any Guarantee or any
      Security Document shall be deemed to impose any duty or obligation on the
      Corporate Trustee to perform any act or acts or exercise any right, power,
      duty or obligation conferred or imposed on it, in any jurisdiction in
      which it shall be illegal, or in which the Corporate 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 Corporate Trustee in such
      jurisdiction or impose a tax on the Corporate Trustee by reason thereof.
      The Individual Trustee, to the extent that he may lawfully so delegate and
      that the Corporate Trustee is permitted by law to exercise the power so
      delegated, and to the extent that such delegation is not inconsistent with
      the preceding sentence and does not impair the right, title and interest
      of the Individual Trustee under, or the validity of the Lien of, this
      Trust Agreement and the Security Documents, (i) may delegate to the
      Corporate Trustee the exercise of any power, discretionary or otherwise,
      conferred by the provisions of this Trust Agreement, any Guarantee or any
      Security Document, and (ii) hereby makes, constitutes and appoints the
      Corporate Trustee, his true and lawful attorney for him and in his name,
      or in the name of the Corporate Trustee, to do and perform all acts
      necessary or proper in the execution and prosecution of the duties of the
      Trustees hereunder in as full and ample a manner as he might do
      personally.

      7.6   MONEYS TO BE HELD IN TRUST.

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

      7.7   RESIGNATION AND REMOVAL OF THE TRUSTEES.

            (a) The Trustees or either of them may at any time, by giving
      written notice of resignation to the Borrower, the Administrative Agent
      and each Holder of Hedging Agreement Obligations, be discharged of the
      responsibilities hereby created, such resignation to become effective upon
      (i) the appointment of a successor Corporate Trustee and/or Individual
      Trustee, as the case may be, (ii) the acceptance of such appointment by
      such successor Trustee, (iii) the approval of such successor Trustee
      evidenced by one or more instruments signed by the Required Secured
      Parties and (iv) in the case of the appointment of a successor Individual
      Trustee, the approval of such successor by the Corporate Trustee. If no
      successor Trustee shall be appointed and shall have accepted such
      appointment within 90 days after the Corporate Trustee or the Individual
      Trustee gives the aforesaid notice of resignation, the Corporate Trustee
      or the resigning Individual Trustee, as the case may be, or any Secured
      Party, may apply to any court of competent jurisdiction to appoint a
      successor Corporate Trustee or Individual


                                       32
<PAGE>

      Trustee, as the case may be, to act until such time, if any, as a
      successor Corporate Trustee or Individual Trustee, as the case may be,
      shall have been appointed as provided in this subsection. Any successor so
      appointed by such court shall immediately and without further act be
      superseded by any successor Corporate Trustee or Individual Trustee, as
      the case may be, appointed as provided in this subsection.

            The Required Secured Parties may, at any time, remove the Trustees
      or either of them and appoint a successor Corporate Trustee or Individual
      Trustee, as the case may be, such removal to be effective upon (i) the
      acceptance of such appointment by the successor, (ii) unless a Notice of
      Enforcement is in effect, the written approval of such successor by the
      Borrower, such approval not to be unreasonably withheld and (iii) in the
      case of the removal of the Individual Trustee, the written approval of the
      appointment of the successor Individual Trustee by the Corporate Trustee.
      The Borrower may, at any time after the merger of the Corporate Trustee as
      contemplated by subsection 7.9, unless a Notice of Enforcement is in
      effect or the Corporate Trustee is the Administrative Agent, remove the
      successor Corporate Trustee and appoint another successor Corporate
      Trustee, such removal to be effective upon (i) the acceptance of such
      appointment by the successor and (ii) the written approval of such
      successor by the Required Secured Parties, such approval not to be
      unreasonably withheld. The Corporate Trustee may, at any time by giving
      written notice to the Borrower, the Administrative Agent, each Holder of
      Hedging Agreement Obligations and the Individual Trustee, remove the
      Individual Trustee and appoint a successor Individual Trustee, such
      removal to be effective upon the acceptance of such appointment by the
      successor Individual Trustee and the receipt by the Corporate Trustee of
      the written approval of such appointment by the Required Secured Parties.
      Any 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 Corporate Trustee or the Individual 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 Corporate Trustee
      or the Individual Trustee for any other cause, a successor Corporate
      Trustee or Individual Trustee, as the case may be, may be appointed by the
      Required Secured Parties; PROVIDED that the appointment of an Individual
      Trustee shall not be effective until written approval of such appointment
      by the Corporate Trustee. If at any time the Individual 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 Individual Trustee for any
      other cause, a successor Individual Trustee may be appointed by the
      Corporate Trustee; PROVIDED that such appointment shall not be effective
      until receipt by the Corporate Trustee of written approval of such
      appointment by the Required Secured Parties. In either case, the powers,
      duties, authority and title of the predecessor Corporate Trustee or
      Individual Trustee, as the case may be, 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 Borrower. 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, the
      Guarantees and the Security Documents shall vest in such


                                       33
<PAGE>

      successor, without any further act, deed or conveyance, all the estates,
      properties, rights, powers, trusts, duties, authority and title of its
      predecessor (subject to the Lien of such predecessor pursuant to
      subsection 5.7); but such predecessor shall, nevertheless, on the written
      request of the Required Secured Parties, the Borrower, 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 Security Documents and shall
      deliver all Collateral held by it or his agents to such successor (subject
      to the Lien of such predecessor pursuant to subsection 5.7). Should any
      deed, conveyance or other instrument in writing from the Borrower be
      required by any successor Corporate Trustee or Individual 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 Corporate Trustee or Individual Trustee, as
      the case may be, any and all such deeds, conveyances and other instruments
      in writing shall, on request of such successor, be executed, acknowledged
      and delivered by the Borrower. If the Borrower 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 Corporate Trustee
      or Individual Trustee, as the case may be, to do so, or if a Notice of
      Enforcement is in effect, the predecessor Corporate Trustee or Individual
      Trustee, as the case may be, may execute the same on behalf of the
      Borrower. The Borrower hereby appoints any predecessor Corporate Trustee
      or Individual Trustee, as the case may be, as its agent and attorney to
      act for it as provided in the next preceding sentence.

            (c) Each of the Trustees agree that, upon the resignation or removal
      of such Trustee pursuant to the terms of this Section 7.7, such Trustee
      shall continue to act as the agent of the Administrative Agent with
      respect to all Uniform Commercial Code financing statements filed in
      connection with any Security Document and shall promptly forward any
      document or request for information received in connection with any such
      financing statement to the Administrative Agent. The Borrower agrees to
      pay all fees of the Trustees, and to reimburse the Trustees for any
      expenses they incur, in accordance with the terms of this Section 7.7.

      7.8   STATUS OF SUCCESSOR CORPORATE TRUSTEE.

      Every successor Corporate Trustee appointed pursuant to subsection 7.7

Corporate Trustee shall be a party, or any person who shall acquire
substantially all of the corporate trust business of the Corporate Trustee shall
be Corporate Trustee under this Trust Agreement and the Security Documents
without the execution or filing of any paper or any further act on the part of

      7.10  CO-TRUSTEE; 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
      Collateral shall be located, or to avoid any violation of law or
      imposition on the Trustees of taxes by such jurisdiction not otherwise
      imposed on the Trustees, or the Corporate Trustee shall be advised by
      counsel, satisfactory to it, that it is necessary or prudent in the
      interest of the Secured Parties, or the Required Secured Parties shall in
      writing so request the Corporate Trustee and the Borrower, or the
      Corporate Trustee shall deem it desirable for its own protection in the
      performance of its duties hereunder or under any Security Document, the
      Corporate Trustee and, unless a Notice of Enforcement is in effect, the
      Borrower 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 Corporate Trustee and, unless a Notice of
      Enforcement is in effect, the Borrower, 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 Security Documents, jointly with the Trustees originally
      named herein or therein or any successor Trustees, or to act as separate
      trustee or trustees of any of the Collateral. If the Borrower shall not
      have joined in the execution of such instruments and agreements within 10
      days after it receives a written request from the Corporate Trustee to do
      so, or if a Notice of Enforcement is in effect, the Corporate Trustee may
      act under the foregoing provisions of this subsection without the
      concurrence of the Borrower and execute and deliver such instruments and
      agreements on behalf of the Borrower. The Borrower hereby appoints the
      Corporate Trustee as its agent and attorney to act for it under the
      foregoing provisions of this subsection in either of such contingencies.

            (b) Every separate trustee and every co-trustee, other than any
      successor Corporate Trustee or Individual Trustee appointed pursuant to
      subsection 7.7, shall, to the extent permitted by law, be appointed and
      act and be such, subject to the following provisions and conditions:

                  (i) all rights, powers, duties and obligations conferred upon
            the Corporate Trustee in respect of the custody, control and
            management of moneys, papers or securities shall be exercised solely
            by the Corporate Trustee or any agent appointed by the Corporate
            Trustee;

                  (ii) all rights, powers, duties and obligations conferred or
            imposed upon the Corporate Trustee hereunder and under the relevant
            Guarantee or Security Document shall be conferred or imposed and
            exercised or performed by the Corporate Trustee and such separate
            trustee or separate trustees or co-trustee or 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


                                       35
<PAGE>

            extent that under any law of any jurisdiction in which any
            particular act or acts are to be performed the Corporate 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 Trustees 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 Guarantee or
            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 Corporate 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 Borrower and the Corporate Trustee, at any time by an
            instrument in writing executed by them jointly, may (and, at the
            direction of the Required Secured Parties, shall) accept the
            resignation of or remove 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 Borrower shall not have joined in
            the execution of any such instrument within 10 days after it
            receives a written request from the Corporate Trustee to do so, or
            if a Notice of Enforcement is in effect, the Corporate Trustee shall
            have the power to (and, at the direction of the Required Secured
            Parties, shall) accept the resignation of or remove any such
            separate trustee or co-trustee and to appoint a successor without
            the concurrence of the Borrower, the Borrower hereby appointing the
            Corporate Trustee its agent and attorney to act for it in such
            connection in such contingency. If the Corporate Trustee shall have
            appointed a separate trustee or separate trustees or co-trustee or
            co-trustees as above provided, the Corporate 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
            Borrower and the Corporate Trustee, or by the Corporate Trustee
            alone pursuant to this subsection.

      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.

      shall present to the Corporate Trustee such documents, including, without
      limitation, Opinions of Counsel, as the Corporate Trustee may reasonably
      require, to demonstrate to the Corporate Trustee the authority of such

      understood that the authority of the Administrative Agent shall be
      demonstrated by its inclusion as such in the lists from time to time
      delivered pursuant to subsection 5.2.).

            (c) Whenever this Trust Agreement requires or permits any Secured
      Party or the Required Secured Parties to sign any instrument, give any
      notice or take any action, the Administrative Agent on behalf of such
      Secured Party or Required Secured Parties may sign such instrument, give
      such notice or take such action with the same effect as if done directly
      by such Secured Party or Required Secured Parties.

applicable bankruptcy, insolvency, reorganization, moratorium or other laws
affecting creditors' rights generally and subject to general principles of
equity, regardless of whether considered in a proceeding in equity or at law.

      3. The execution, delivery and performance by the Borrower of the
Additional Secured Instruments (a) do not require any consent or approval of,
registration or filing with, or any other action by, any Governmental Authority,

other organizational documents of the Borrower or any order of any Governmental
Authority, (c) to our knowledge, do not violate or result in a default under any
indenture, agreement or other instrument evidencing or governing any Material
Indebtedness or any other material indenture, agreement or other instrument
binding upon the Borrower or its assets, or give rise to a right thereunder to
require any payment to be made by the Borrower, and (d) to our knowledge, do not
result in the creation or imposition of any Lien on any asset of the Borrower,
except Liens created under the Security Documents.

      4. To our knowledge, there are no actions, suits or proceedings by or
before any arbitrator or Governmental Authority pending against or threatened
against or affecting the Borrower that involve any of the Additional Secured
Instruments or the transactions contemplated therein.
