     reimbursed prior to such Distribution Date, and, if such moneys shall be
     insufficient to pay such amounts in full, then ratably (without priority of
     any one over any other) to such Secured Parties in proportion to the
     amounts of such Trustee Fees advanced by the respective Secured Parties and
     remaining unpaid on such Distribution Date;

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

     constitute Other Secured Obligations, including without limitation the
     costs and expenses of the Secured Parties and their representatives which
     are due and payable under the relevant Secured Instruments and which
     constitute Other Secured Obligations as of such Distribution Date (but only
     to the extent such Other Secured Obligations constitute Restricted

     such moneys shall be insufficient to pay such amounts in full, then ratably
     to the Secured Parties in proportion to the unpaid amounts thereof on such
     Distribution Date; and

          Sixth: any surplus then remaining shall be paid to the Obligors or
          -----
     their successors or assigns or to whomsoever may be lawfully entitled to
     receive the same or as a court of competent jurisdiction may direct.

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

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

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

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

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

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

                                     -17-
<PAGE>

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

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

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

                                  SECTION 4.

directions hereunder on behalf of such parties, the Trustee may rely on any
person purporting to be authorized to give directions hereunder on behalf of
such parties. If the Trustee is not informed of changes of the officers of the
Administrative Agent or any Surety Party authorized to give directions hereunder
on behalf of such parties, the Trustee may rely on the information previously
provided to the Trustee.

          ------------------------------
Trustee, from time to time upon demand, (i) reasonable compensation (which shall

Trust Agreement and the resignation or removal of the Trustee hereunder.

          4.4  Stamp and Other Similar Taxes. The Company agrees to indemnify
          ----------------------------------

resignation or removal of the Trustee hereunder.

          4.6  Indemnification. The Company agrees to pay, indemnify, and hold
          --------------------
the Trustee, the Administrative Agent and each Surety Party (and their
respective directors, officers, agents and employees) harmless from and against
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses (including, without limitation, the reasonable
fees and expenses of counsel, advisors and agents) or disbursements of any kind
or nature whatsoever with respect to the execution, delivery, enforcement,
performance and administration of this Trust Agreement and the Trust Security
Documents, unless arising from the gross negligence or willful misconduct of the
indemnified party, including for taxes in any jurisdiction in which the Trustee
is subject to tax by reason of actions hereunder or under the Trust Security
Documents, unless such taxes are imposed on or measured by compensation paid to
the Trustee under Section 4.3. In any suit, proceeding or action brought by the
Trustee 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 Company will save, indemnify and keep the Trustee,
the Administrative Agent each Surety Party and the Secured Parties harmless from

Obligor, and all such obligations of the Company shall be and remain enforceable
against and only against the Company and shall not be enforceable against the
Trustee, the Administrative Agent, any Surety Party or any Secured Party. The
agreements in this Section 4.6 shall survive the termination of the other
provisions of this Trust Agreement and the resignation or removal of the Trustee
hereunder.

          4.7  Trustee's Lien. Notwithstanding anything to the contrary in this
          -------------------
Trust Agreement, as security for the payment of Trustee Fees (i) the Trustee is
hereby granted a lien upon all Collateral prior to all Secured Parties and (ii)
the Trustee shall have the right to use and apply any of the funds held by the
Trustee in the Collateral Account to cover such Trustee Fees.

          4.8  Further Assurances. At any time and from time to time, upon the
          -----------------------
written request of the Administrative Agent or the Trustee, and at the expense
of the Company, each Obligor will promptly execute and deliver any and all such
further instruments and documents and take such further action as is necessary
or reasonably requested further to perfect, or to protect the perfection of, the
liens and security interests granted under the Trust Security Documents,
including, without limitation, the filing of any financing or continuation

<PAGE>

at any time and from time to time, upon the written request of the Trustee

Documents. Each Obligor also hereby authorizes the Trustee to sign and the
Administrative Agent or the Trustee to file any such financing or continuation
statements without the signature of such Obligor to the extent permitted by
applicable law. Notwithstanding the foregoing, in no event shall the Trustee
have any obligation in respect of the perfection or continuation of perfection,
the sufficiency or validity of any security interest in or related to the
Collateral or to prepare or file any Uniform Commercial Code financing
statements.

          4.9  Obligors. The Obligors agree, jointly and severally, to pay to
          -------------
the Trustee any of the amounts payable to it pursuant to this Section 4 to the
extent not paid by the Company.

                                  SECTION 5.

                                  THE TRUSTEE

          5.1  Acceptance of Trust. The Trustee, for itself and its successors,
          ------------------------
hereby accepts the trusts created by this Trust Agreement upon the terms and
conditions hereof.

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

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

                                     -21-
<PAGE>

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 Trustee, whereupon on the next Distribution Date the amount
distributable to such Person shall be recalculated using such information and
distributed to it. Nothing in the preceding sentence shall prevent any Obligor
from contesting any amounts claimed by any Secured Party in any certificate so
supplied.

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

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

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

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

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

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

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

                                     -22-
<PAGE>

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

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

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

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

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

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

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

                                     -23-
<PAGE>

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

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

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

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

                                     -24-
<PAGE>

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

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

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

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

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

                                     -25-

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

          (ii)  all rights, powers, duties and obligations conferred or imposed
     upon the Trustee hereunder and under the relevant Trust Security Document
     or Documents shall be conferred or imposed and exercised or performed by
     the 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 extent that under any law of any jurisdiction in which any
     particular act or acts are to be performed the Trustee shall be incompetent
     or unqualified to perform such act or acts, or unless the performance of
     such act or acts would result in the imposition of any tax on the Trustee
     which would not be imposed absent such joint act or acts, in which event
     such rights, powers, duties and obligations shall be exercised and
     performed by such separate trustee or separate trustees or co-trustee or
     co-trustees;

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

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

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

may reasonably require, in order to demonstrate to the Trustee the authority of

hereunder by the Administrative Agent and the holders of the Surety Bond
Obligations are represented hereunder by the relevant Surety Party and (ii) such
