directed in writing by the Owner Participant. For all purposes of this Trust
Agreement and the Lease, the Owner Trustee shall not be deemed to have knowledge
of an Event of Loss, a Default or an Event of Default unless notified in writing
thereof in the manner and at the address set forth in Section 10.05 or unless an

to the terms of Sections 5.01 and 5.03 and to the terms of the other Operative
Agreements, upon the written instructions at any time and from time to time of
the Owner Participant, the Owner Trustee will take such of the following actions
as may be specified in such instructions: (i) give such notice or direction or
exercise such right, remedy or power hereunder or under any of the Operative
Agreements to which the Owner Trustee is a party, or in respect of all or any
part of the Trust Estate, as shall be specified in such instructions; (ii) take
such action to preserve or protect the Trust Estate (including the discharge of
any Liens or encumbrances) as may be specified in such instructions; (iii)
approve as satisfactory to it all matters required by the terms of the Lease to
be satisfactory to

the Owner Trustee, it being understood that without written instructions of the
Owner Participant, the Owner Trustee shall not approve any such matter as
satisfactory to it; (iv) after the expiration or earlier termination of the
Lease, convey all of the Owner Trustee's right, title and interest in and to the
Aircraft for such amount, on such terms and to such purchaser or purchasers as

of, or from time to time take such action with respect to, the Aircraft on such
terms as shall be set forth in such instructions or deliver the Aircraft to the
Owner Participant in accordance with such instructions; and (v) take or refrain
from taking such other action or actions as may be specified in such

instructions of the Owner Participant.

required to take or refrain from taking any action under Section 5.01 (other
than the giving of notices referred to therein) or 5.02 unless the Owner Trustee
shall have been indemnified by the Lessee or the Owner Participant, as
appropriate, in manner and form satisfactory to the Owner Trustee, against any
liability, cost or expense (including reasonable counsel fees and disbursements)
which may be incurred in connection therewith. The Owner Trustee shall not be
required to take any action under Section 5.01 or 5.02 if the Owner Trustee
shall reasonably determine, or shall have been advised by counsel, that such
action is contrary to the terms of any of the Operative Agreements to which the
Owner Trustee is a party, or is otherwise contrary to Applicable Law.

               Section 5.04.  No Duties Except as Specified in Trust Agreement
                              ------------------------------------------------

manage, control, use, sell, dispose of or otherwise deal with the Aircraft or

the Owner Trustee is a party, except as expressly required by the terms of any
of the Operative Agreements to which the Owner Trustee is a party, or as
expressly provided by the terms hereof or in written instructions from the Owner
Participant received pursuant to the terms of Section 5.01 or 5.02, and no
implied duties or obligations shall be read into this Trust Agreement or any of
the Operative Agreements to which the Owner Trustee is a party against the Owner
Trustee. The Owner Trustee nevertheless agrees that it will, in its individual
capacity and at its own cost and expense (but without any right of indemnity in
respect of any such cost or expense under Section 7.01) promptly take such
action as may be necessary duly to discharge and satisfy in full (i) its
obligations under Section 5.03(b) of the Participation Agreement, (ii) any Liens
(other than Lessor's Liens attributable to it in its individual capacity)
created as a result of its breach of any of its obligations under this Trust
Agreement (subject to the limitations on the liability of the Owner Trustee in
its individual capacity set forth in Section 6.01) on any part of the Trust
Estate, or on any properties of the Owner Trustee assigned, pledged or mortgaged
as part of the Trust Estate, which arise from acts of the Owner Trustee in its
individual capacity, the rights of Lessee under the Lease and the rights of the
Owner Participant hereunder, and (iii) any other Liens or encumbrances
attributable to the Owner Trustee in its individual capacity on any part of the
Trust Estate which result from claims against the

Owner Trustee in its individual capacity unrelated to the ownership of the

provided by the terms hereof, or (iii) as expressly provided in written

purposes hereof rely on a certificate signed by a Responsible Officer of Lessee

faith by it in accordance with the advice or opinion of any such counsel,
accountants or other skilled persons selected by it with reasonable care;
provided, the Owner Trustee agrees that it shall endeavor to give the Owner
Participant notice that

having any claim against the Owner Trustee by reason of the transactions
contemplated hereby shall look only to the Trust Estate for payment or

responsible for the keeping of all appropriate books and records relating to the
receipt and disbursement by it of all monies under this Trust Agreement, the
other Operative Agreements or any agreement contemplated hereby. The Owner
Trustee shall be responsible for causing to be prepared and timely filed, at
Lessee's expense, the federal fiduciary tax return required to be filed with
respect to the trust created hereby and such other tax returns requested by the
Owner Participant and shall execute and file such returns as directed by the
Owner Participant.

relating to or arising out of the administration of the Trust Estate or the
action or inaction of the Owner Trustee hereunder, except (a) in the case of
willful misconduct or gross negligence on the part of the Owner Trustee either
as trustee or in its individual capacity in the performance or nonperformance of
its duties hereunder or under any of the other Operative Agreements to which it
is a party or (b) those resulting from the inaccuracy of any representation or
warranty of the Owner Trustee in its individual capacity (or from the failure of
the Owner Trustee in its individual capacity to perform any covenant) in Section
6.03, or in any of the Operative Agreements, or (c) those arising or resulting
from any of the matters described in the last sentence of Section 6.01, or (d)
those resulting from its failure to perform the terms of the last sentence of
Section 5.04 hereof or from its failure to use ordinary care in the receipt and

reimbursement from the Trust Estate (but, in either case, need not exhaust any
or all remedies available thereunder). The indemnities contained in this Section
7.01 extend to the Owner Trustee only in its individual capacity and shall not
be construed as indemnities of the Trust Estate. The indemnities contained in
this Section 7.01 shall survive the termination of this Trust Agreement and the

Successor. Resignation or Removal. The Owner Trustee or any successor Owner
---------
Trustee (i) shall resign if required to do so pursuant to Section 5.02(b) of the
Participation Agreement and (ii) may resign

                                       12
<PAGE>

at any time without cause by giving at least 60 days prior written notice to the
Owner Participant and Lessee, such resignation to be effective upon the
acceptance of appointment by the successor Owner Trustee under Section 8.01(b).
In addition, the Owner Participant may at any time remove the Owner Trustee, or
revoke the trusts created by this Trust Agreement, in either case with or
without cause by a notice in writing delivered to the Owner Trustee and Lessee.
Any such removal shall be effective upon the acceptance of appointment by the
successor Owner Trustee under Section 8.01(b). In the case of the resignation or
removal of the Owner Trustee, the Owner Participant may appoint a successor
Owner Trustee by an instrument in writing. If a successor Owner Trustee shall
not have been appointed within 30 days after such notice of resignation or
removal, the Owner Trustee may apply to any court of competent jurisdiction to
appoint a successor Owner Trustee to act until such time, if any, as a successor
shall have been appointed as above provided. Any successor Owner Trustee so
appointed by such court shall immediately and without further act be superseded
by any successor Owner Trustee appointed as above provided within one year from
the date of the appointment by such court. All reasonable fees and expenses of a
successor Owner Trustee appointed in accordance with this Section 8.01 and the
provisions of paragraph (b) of Section 9.01 of the Participation Agreement shall
be at Lessee's sole cost and expense.

          (b)  Execution and Delivery of Documents, etc. Any successor Owner
               ----------------------------------------
Trustee, however appointed, shall execute and deliver to the predecessor Owner
Trustee, with a copy to Owner Participant and Lessee, an instrument accepting
such appointment and assuming the obligations of Owner Trustee, in its
individual capacity and as Owner Trustee, under the Operative Agreements to
which Owner Trustee is a party, and thereupon such successor Owner Trustee,
without further act, shall become vested with all the estates, properties,
rights, powers, duties and trusts of the predecessor Owner Trustee in the trust
hereunder with like effect as if originally named the Owner Trustee herein; but
nevertheless, upon the written request of such successor Owner Trustee, such
predecessor Owner Trustee shall execute and deliver an instrument transferring
to such successor Owner Trustee upon the trusts herein expressed, all the
estates, properties, rights, powers and trusts of such predecessor Owner
Trustee, and such predecessor Owner Trustee shall duly assign, transfer, deliver
and pay over to such successor Owner Trustee all monies or other property then
held by such predecessor Owner Trustee upon the trusts herein expressed. Upon
the appointment of any successor Owner Trustee hereunder, the predecessor Owner
Trustee will complete, execute and deliver to the successor Owner Trustee such
documents as are necessary to cause registration of the Aircraft included in the
Trust Estate to be transferred upon the records of the FAA or other governmental
authority having jurisdiction, into the name of the successor Owner Trustee.

          (c)  Qualification. Any successor Owner Trustee, however appointed,
               -------------
shall be a Citizen of the United States, shall be qualified to act as a trustee
in Delaware (if the trust created hereby is to remain in such state) and shall
also be a bank or trust company organized under the laws of the United States of
America or any state thereof having a combined capital and surplus of at least
$100,000,000, if there be such an institution willing, able and legally
qualified to perform the duties of the Owner Trustee hereunder upon reasonable
and customary terms.

<PAGE>

          (d)  Merger, etc. Any corporation into which the Owner Trustee may be
               -----------
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Owner
Trustee shall be a party, or any corporation to which substantially all the
corporate trust business of the Owner Trustee may be transferred, shall, subject
to the terms of Section 8.01(c), be the Owner Trustee hereunder without further
act.

          Section 8.02. Co-Trustees and Separate Trustees. If at any time or
                        ---------------------------------
times it shall be necessary or prudent in order to conform to any Applicable Law
of any jurisdiction in which all or any part of the Trust Estate is located, or
the Owner Trustee shall be advised by counsel that it is so necessary or prudent
in the interest of the Owner Participant or the Owner Trustee, or the Owner
Trustee shall have been directed to do so by the Owner Participant, the Owner
Trustee and the Owner Participant shall execute and deliver an agreement
supplemental hereto and all other instruments and agreements necessary or proper
to constitute another bank or trust company or one or more Persons (any and all
of which shall be a Citizen of the United States) approved by the Owner Trustee
and the Owner Participant, either to act as co-trustee or co-trustees, jointly
with the Owner Trustee, or to act as separate trustee or trustees hereunder (any
such co-trustee or separate trustee being herein sometimes referred to as an
"additional trustee"). In the event the Owner Participant shall not have joined
in the execution of such agreements supplemental hereto within ten days after
the receipt of a written request from the Owner Trustee so to do, the Owner
Trustee may act under the foregoing provisions of this Section 8.02 without the
concurrence of the Owner Participant; and the Owner Participant hereby appoints
the Owner Trustee its agent and attorney-in-fact to act for it under the
foregoing provisions of this Section 8.02 in either of such contingencies. All
reasonable fees and expenses of a co-trustee or separate trustee appointed in
accordance with this Section 8.02 shall be at Lessee's sole cost and expense.

          Every additional trustee hereunder shall, to the extent permitted by
Applicable Law, be appointed and act, and the Owner Trustee and its successors
shall act, subject to the following provisions and conditions:

          (a)  all powers, duties, obligations and rights conferred upon the
     Owner Trustee in respect of the custody, control and management of monies,
     the Aircraft or documents authorized to be delivered hereunder or under the
     Participation Agreement shall be exercised solely by the corporation
     designated as the Owner Trustee in the first paragraph of this Trust
     Agreement, or its successors as the Owner Trustee hereunder;

          (b)  all other rights, powers, duties and obligations conferred or
     imposed upon the Owner Trustee and any limitations thereon shall be
     conferred or imposed upon and exercised or performed by the corporation
     designated as the Owner Trustee in the first paragraph of this Trust
     Agreement or its successors as the Owner Trustee, and such additional
     trustee or trustees jointly, except to the extent that under any Applicable
     Law of any jurisdiction in which any particular act or acts are to be
     performed (including the holding of title to the Trust Estate), the Owner
     Trustee shall be incompetent or unqualified to perform such act or

                                       14

     acts, in which event such rights, powers, duties and obligations shall be
     exercised and performed by such additional trustee or trustees;

          (c)  no power given to, or which it is provided hereby may be
     exercised by, any such additional trustee or trustees shall be exercised
     hereunder by such additional trustee or trustees, except jointly with, or
     with the consent in writing of, the corporation designed as the Owner
     Trustee in this Trust Agreement or its successor as the Owner Trustee,
     anything herein contained to the contrary notwithstanding;

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

          (e)  the Owner Participant, at any time, by an instrument in writing
     may remove any such additional trustee. In the event that the Owner
     Participant shall not have joined in the execution of any such instrument
     within ten days after the receipt of a written request from the Owner
     Trustee so to do, the Owner Trustee shall have the power to remove any such
     additional trustee without the concurrence of the Owner Participant; and
     the Owner Participant hereby appoints the Owner Trustee its agent and
     attorney-in-fact to act for it in such connection in such contingency.

          In case any separate trustee under this Section 8.02 shall die, become
incapable of acting, resign or be removed, the title to the Trust Estate and all
rights and duties of such separate trustee shall, so far as permitted by
Applicable Law, vest in and be exercised by Owner Trustee, without the
appointment of a successor to such separate trustee.

Trustee to protect the Trust Estate and Owner Trustee against any and all

fully complied with all of the terms of the Participation Agreement and the

shall become effective providing for the validity of this Trust Agreement and
the trusts created hereby and the effective grant of such rights, privileges and

valid), then such rights, privileges or options shall not terminate as aforesaid
but shall extend to and continue in effect, but only if such non-termination and
extension shall then be valid under Applicable Law, until such time as the same
