or power under this Trust Agreement or any of the other Owner Trustee Agreements
or in respect of all or any part of the Trust Estate, or take such other action,

agreements and instruments as shall be necessary under Section 10); (b) take
such action to preserve or protect the Trust Estate (including the discharge of
Liens) as may be specified in such instructions; (c) approve as satisfactory to
it all matters required by the terms of the Lease or the other Operative
Agreements to be satisfactory to Owner Trustee, it being understood that without
written instructions of Owner Participant, Owner Trustee shall not approve any
such matter as satisfactory to it; (d) subject to the rights of Lessee under the
Operative Agreements, after the expiration or earlier termination of the Lease,
convey all of 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 shall be
designated in such instructions, or retain, lease or otherwise dispose of, or
from time to time take such other action with respect to, the Aircraft on such
terms as shall be designated in such instructions; and (e) take or refrain from
taking such other action or actions as may be specified in such instructions.

            5.3   Limitations on Duties

            Owner Trustee shall not be required to take any action under Section
5.1 (other than the giving of the notices referred to therein) or 5.2 if Owner
Trustee shall reasonably believe such action is not adequately indemnified by
Owner Participant under Section 7, unless Lessee or Owner Participant agrees to
furnish such additional indemnity as shall reasonably be required, in manner and
form satisfactory to Owner Trustee, and, in addition to the extent not otherwise
paid pursuant to the provisions of the Lease or of the Participation Agreement,
to pay the reasonable compensation of Owner Trustee for the services performed
or to be performed by it pursuant to such direction and any reasonable fees and
disbursements of counsel or agents employed by Owner Trustee in connection
therewith. Owner Trustee shall not be required to take any action under Section
5.1 or 5.2 (other than the giving of the notices referred to therein) if Owner
Trustee shall have been advised by counsel that such action is contrary to the
terms of any of the Owner Trustee Agreements or is otherwise contrary to Law and
Owner Trustee has delivered to Owner Participant written notice of the basis for
its refusal to act.

Mortgagee and Owner Participant, promptly upon receipt thereof, duplicates or
copies of all reports, notices, requests, demands, certificates, financial
statements and other instruments furnished to Owner Trustee under the Lease or
any other Operative Agreement except to the extent to which a responsible
officer of Owner Trustee reasonably believes (and confirms by telephone call
with Owner Participant) that duplicates or copies thereof have already been
furnished to Owner Participant by some other person.

            6.3   No Representations or Warranties as to Certain Matters

            NEITHER WELLS FARGO NOR OWNER TRUSTEE MAKES OR SHALL BE DEEMED TO
HAVE MADE (a) ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO THE

FITNESS FOR USE FOR A PARTICULAR PURPOSE OF THE AIRCRAFT OR ANY PART THEREOF, AS

representation or warranty as to the validity, legality or enforceability of
this Trust Agreement or any other Operative Agreement to which Wells Fargo, in
its individual capacity or as Owner Trustee, is a party, or any other document
or instrument, or as to the correctness of any statement contained in any
thereof except to the extent that any such statement is expressly made herein or
therein by such party as a representation by Wells Fargo, in its individual
capacity or as Owner Trustee, as the case may be, and except that Wells Fargo
hereby represents and warrants that it has all corporate power and authority to
execute, deliver and perform this Trust Agreement and that this Trust Agreement
has been, and (assuming due authorization, execution and delivery by Owner
Participant of this Trust Agreement) the other Operative Agreements to which it
or Owner Trustee is a party have been (or at the time of execution and delivery
of any such instrument by it or Owner Trustee under this Trust Agreement or
pursuant to the terms of the Participation Agreement that such an instrument
will be) duly executed and delivered by one of its officers who is or will be,
as the case may be, duly authorized to execute and deliver such instruments on
behalf of itself or Owner Trustee, as the case may be, and that this Trust
Agreement constitutes the legal, valid and binding obligation of Wells Fargo or
Owner Trustee, as the case may be, enforceable against Wells Fargo or Owner
Trustee, as the case may be, in accordance with its terms.

            6.4   No Segregation of Monies; Interest

            Monies received by Owner Trustee under this Trust Agreement need not
be segregated in any manner except to the extent required by Law, or except as

<PAGE>

            6.5   Reliance upon Certificates, Counsel and Agents

            Owner Trustee shall incur no liability to anyone in acting in good
faith in reliance upon and in accordance with any signature, instrument, notice,
resolution, request, consent, order, certificate, report, opinion, bond or other
document or paper reasonably believed by it to be genuine and reasonably
believed by it to be signed by the proper party or parties. Unless other
evidence in respect thereof is specifically prescribed in this Trust Agreement,
any request, direction, order or demand of Owner Participant or Lessee mentioned
in this Trust Agreement or in any of the other Owner Trustee Agreements shall be
sufficiently evidenced by written instruments signed by the Chairman of the
Board, the President, any Vice President or any other officer and in the name of
Owner Participant or Lessee, as the case may be. Owner Trustee may accept a copy
of a resolution of the Board of Directors or Executive Committee of Lessee,
certified by the Secretary or an Assistant Secretary of Lessee as duly adopted
and in full force and effect, as conclusive evidence that such resolution has
been duly adopted by said Board of Directors or Executive Committee and that the
same is in full force and effect. As to any fact or matter the manner of
ascertainment of which is not specifically described in this Trust Agreement,
Owner Trustee may, absent Actual Knowledge to the contrary, for all purposes
rely on a certificate signed by the Chairman of the Board, the President, any
Vice President or any other officer of Lessee, and the Treasurer or an Assistant
Treasurer or the Secretary or an Assistant Secretary of Lessee, as to such fact
or matter, and such certificate shall constitute full protection to Owner
Trustee for any action taken or omitted to be taken by it in good faith in
reliance thereon and in accordance therewith. In the administration of trusts
under this Trust Agreement, Owner Trustee may execute any of the trusts or
powers and perform its powers and duties under this Trust Agreement directly or
through agents or attorneys and may, at the expense of the Trust Estate, consult
with counsel, accountants and other skilled persons to be selected and employed
by it. Owner Trustee shall not be liable for anything done, suffered or omitted
in good faith by it in accordance with the advice or opinion of any such
counsel, accountants or other skilled persons.

            6.6   Not Acting in Individual Capacity

            In acting under this Trust Agreement, Wells Fargo acts solely as
Owner Trustee and not in its individual capacity except as otherwise expressly
provided in this Trust Agreement or in the other Operative Agreements to which
it is a party; and, except as may be otherwise expressly provided in this Trust
Agreement, the Lease, the Participation Agreement and the Trust Indenture, all
persons, other than the Owner Participant as provided in this Trust Agreement or
the Trust Indenture, having any claim against Owner Trustee by reason of the
transactions contemplated hereby shall look only to the Trust Estate for payment
or satisfaction thereof except to the extent provided in Section 6.1 or
otherwise as Owner Trustee shall expressly agree otherwise in writing.

            6.7   Fees; Compensation

            Airframe Manufacturer shall pay the Transaction Expenses and ongoing
fees of Owner Trustee throughout the Term pursuant to Section 9.2 of the
Participation Agreement. The Trust Estate shall not have any liability for any
such fees and expenses; PROVIDED, that the foregoing shall not limit the
obligations of Owner Participant under Sections 5.3 and 7; PROVIDED, that Owner

<PAGE>

Trustee shall have a Lien upon the Trust Estate for any such fee not paid by
Airframe Manufacturer as contemplated by Section 9.2 of the Participation
Agreement and such Lien shall entitle Owner Trustee to priority as to payment
thereof over payment to any other Person under this Trust Agreement; PROVIDED,
that such Lien shall be subject and subordinate in all events to the Lien of the
Trust Indenture; and PROVIDED, FURTHER, that Owner Trustee shall have no right
to exercise, and shall not exercise, any rights or remedies Owner Trustee may
have with respect to such Lien unless and until the Secured Obligations have
been paid and performed in full.

            6.8   Tax Returns

            Owner Trustee shall be responsible for the keeping of all
appropriate books and records relating to the receipt and disbursement of all
monies under this Trust Agreement or any agreement contemplated hereby. Owner
Participant shall be responsible for causing to be prepared and filed all income
tax returns required to be filed by Owner Participant. Owner Trustee shall be
responsible for causing to be prepared, at the expense of Airframe Manufacturer,
all income tax returns required to be filed with respect to the trust created
hereby and shall execute and file such returns; PROVIDED, that Owner Trustee
shall send promptly a completed copy of such return to Owner Participant not
more than sixty nor less than fifteen days prior to the due date of the return,
PROVIDED, that Owner Trustee shall have timely received all necessary
information to complete and deliver to Owner Participant such return. Owner
Participant, upon request, will furnish Owner Trustee with all such information
as may be reasonably required from Owner Participant in connection with the
preparation of such income tax returns. Owner Trustee shall keep copies of all
returns delivered to or filed by it.

            SECTION 7.  INDEMNIFICATION OF WELLS FARGO BY OWNER
PARTICIPANT

            Owner Participant hereby agrees, whether or not any of the
transactions contemplated hereby shall be consummated, to assume liability for,
and hereby indemnifies, protects, saves and keeps harmless, Wells Fargo and its
successors, assigns, agents and servants, from and against any and all
liabilities, obligations, losses, damages, penalties, taxes (excluding any Taxes
which are not required to be indemnified by Lessee pursuant to Section 9.1 or
9.3 of the Participation Agreement and excluding any taxes payable by Wells
Fargo on or measured by any compensation received by Wells Fargo for its
services under this Trust Agreement), claims, actions, suits, costs, expenses or
disbursements (including, without limitation, reasonable legal fees and
expenses, but excluding internal costs and expenses such as salaries and
overhead, and including, without limitation, any liability of an owner, any
strict liability and any liability without fault) of any kind and nature
whatsoever which may be imposed on, incurred by or asserted against Wells Fargo
(whether or not also indemnified against by Lessee under the Lease or under the
Participation Agreement or also indemnified against by any other Person;
PROVIDED, that Owner Participant shall be subrogated to the rights of Owner
Trustee against Lessee or any other indemnitor) in any way relating to or
arising out of this Trust Agreement or any of the other Operative Agreements or
the enforcement of any of the terms of any thereof, or in any way relating to or
arising out of the manufacture, purchase, acceptance, nonacceptance, rejection,
ownership, delivery, lease, possession, use, operation, condition, sale, return
or other disposition of the Aircraft (including, without limitation, latent and
other defects, whether or not discoverable, and any claim for patent, trademark
or copyright infringement), or in any way relating to or arising out of the

<PAGE>

administration of the Trust Estate or the action or inaction of Owner Trustee,
under this Trust Agreement, except (a) in the case of gross negligence or
willful misconduct on the part of Wells Fargo, in its individual capacity or as
Owner Trustee, in the performance or nonperformance of its duties under this
Trust Agreement or under any of the other Owner Trustee Agreements or (b) those
Claims resulting from the inaccuracy of any representation or warranty of Wells
Fargo (or from the failure of Wells Fargo to perform any of its covenants) in
Section 6.3 of this Trust Agreement, in Section 6.03 of the Trust Indenture, in
Section 4 of the Lease, in Section 6.3 and Section 7.3 of the Participation
Agreement or elsewhere in any of the other Operative Agreements or (c) as may
result from a breach by Wells Fargo of its covenant in the last sentence of
Section 5.4.1 or (d) in the case of the failure to use ordinary care on the part
of Wells Fargo, in its individual capacity or as Owner Trustee, in the receipt
or disbursement of funds or in connection with its obligation to invest funds
pursuant to Section 4 of the Participation Agreement, Section 4.4 of the Lease
or Section 4.3 hereof or in compliance with the provisions of the first sentence
of Section 6.8 or (e) any liability on the part of Owner Trustee arising out of
its negligence or willful or negligent misconduct in connection with its
obligations under Section 5.1, 6.8 or 9.2 hereof or Section 4.01 of the Trust
Indenture, or (f) those claims arising under any circumstances or upon any terms
where Lessee would not have been required to indemnify Wells Fargo pursuant to
Section 9.1 or 9.3 of the Participation Agreement (disregarding for purposes of
this paragraph Sections 9.1.2(b) and 9.3.2(j)); PROVIDED, that before asserting
its right to indemnification, if any, pursuant to this Section 7, Wells Fargo
shall first demand its corresponding right to indemnification pursuant to
Section 9 of the Participation Agreement (but need not exhaust any or all
remedies available thereunder). The indemnities contained in this Section 7
extend to Wells Fargo only in its individual capacity and shall not be construed
as indemnities of the Trust Indenture Estate or the Trust Estate (except to the
extent, if any, that Wells Fargo has been reimbursed by the Trust Indenture
Estate or the Trust Estate for amounts covered by the indemnities contained in
this Section 7). The indemnities contained in this Section 7 shall survive the
termination of this Trust Agreement. In addition, if necessary, Wells Fargo
shall be entitled to indemnification from the Trust Estate, subject to the Lien
of the Trust Indenture, for any liability, obligation, loss, damage, penalty,
tax, claim, action, suit, cost, expense or disbursement indemnified against
pursuant to this Section 7 to the extent not reimbursed by Lessee, Owner
Participant or others, but without releasing any of them from their respective
agreements of reimbursement; and, to secure the same Wells Fargo shall have a
lien on the Trust Estate, subject to the lien of the Trust Indenture and subject
further to the provisions of Section 6.7, which shall be prior to any interest
therein of Owner Participant. The payor of any indemnity under this Section 7
shall be subrogated to any right of the person indemnified in respect of the
matter as to which such indemnity was paid.

            SECTION 8.  TRANSFER OF OWNER PARTICIPANT'S INTEREST

            8.1   Transfer of Interest

            All provisions of Section 10 of the Participation Agreement shall
(with the same force and effect as if set forth in full in this Section 8.1) be
applicable to any assignment, conveyance or other transfer by Owner Participant
of any of its right, title or interest in and to the Participation Agreement,
the Trust Estate or this Trust Agreement.

            SECTION 9.  SUCCESSOR OWNER TRUSTEES; CO-TRUSTEES

            9.1   Resignation of Owner Trustee; Appointment of Successor

                  9.1.1 Resignation or Removal

            Owner Trustee or any successor Owner Trustee (a) shall resign if
required to do so pursuant to Section 13.3 of the Participation Agreement or
upon obtaining Actual Knowledge of any facts that would cast doubt upon its
continuing status as a Citizen of the United States and (b) may resign at any
time without cause by giving at least 60 days' prior written notice to Owner
Participant, Mortgagee and Lessee, such resignation to be effective upon the
assumption of the trusts hereunder by the successor Owner Trustee under Section
9.1.2. In addition, subject to Section 12.1(b), Owner Participant may at any
time remove Owner Trustee, but only with cause by a notice in writing delivered
to Owner Trustee, Mortgagee and Lessee, such removal to be effective upon the
assumption of the trusts hereunder by the successor Owner Trustee under Section
9.1.2. In the case of the resignation or removal of Owner Trustee, Owner
Participant may appoint a successor Owner Trustee by an instrument signed by
Owner Participant, with, unless a Lease Event of Default shall have occurred and
be continuing, the consent of Lessee (which consent shall not be unreasonably
withheld). If a successor Owner Trustee shall not have been appointed within 30
days after such notice of resignation or removal, Owner Trustee, Owner
Participant, Lessee or Mortgagee 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.

                  9.1.2 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,
Lessee and Mortgagee, an instrument accepting such appointment and assuming the
obligations of Owner Trustee, in its individual capacity and as Owner Trustee,
under the Owner Trustee Agreements, 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 trusts
under this Trust Agreement with like effect as if originally named Owner Trustee
in this Trust Agreement; 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
under this Section 9.1, the predecessor Owner Trustee will execute such
documents as are provided to it by such successor Owner Trustee and will take
such further actions as are requested of it by such successor Owner Trustee as
are required 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.


<PAGE>

                  9.1.3 Qualifications

            Any successor Owner Trustee, however appointed, shall be a Citizen
of the United States and shall also be a bank or trust company organized under
the Laws of the United States 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 Owner Trustee under this Trust
Agreement upon reasonable or customary terms. No such successor Owner Trustee
shall be located in a jurisdiction which creates material adverse consequences
for Lessee (unless such material adverse consequences would be created by
substantially all jurisdictions where major banking or trust institutions are
located).

                  9.1.4 Merger, Etc.

            Any corporation into which Wells Fargo may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which Wells Fargo shall be a party, or any
corporation to which substantially all the corporate trust business of Wells
Fargo may be transferred, shall, subject to the terms of Section 9.1.3, be Owner
Trustee under this Trust Agreement without further act, PROVIDED, that such
corporation shall not also be the Mortgagee.

            9.2   Co-Trustees and Separate Trustees

            (a) If at any time it shall be necessary or prudent in order to
      conform to any Law of any jurisdiction in which all or any part of the
      Trust Estate is located, or Owner Trustee being advised by counsel shall
      determine that it is so necessary or prudent in the interest of Owner
      Participant or Owner Trustee, or Owner Trustee shall have been directed to
      do so by Owner Participant, Owner Trustee and 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 or all of which shall be a
      Citizen of the United States) approved by Owner Trustee and Owner
      Participant, either to act as co-trustee, jointly with Owner Trustee, or
      to act as separate trustee under this Trust Agreement (any such co-trustee
      or separate trustee being herein sometimes referred to as an "additional
      trustee"). In the event 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 Owner Trustee so to do, or in case a
      Lease Event of Default or Indenture Event of Default shall occur and be
      continuing, Owner Trustee may act under the foregoing provisions of this
      Section 9.2 without the concurrence of Owner Participant; and Owner
      Participant hereby appoints Owner Trustee its agent and attorney-in-fact
      to act for it under the foregoing provisions of this Section 9.2 in either
      of such contingencies.

            (b) Every additional trustee under this Trust Agreement shall, to
      the extent permitted by Law, be appointed and act, and Owner Trustee and
      its successors shall act, subject to the following provisions and
      conditions:

            (i) All powers, duties, obligations and rights conferred upon Owner
      Trustee in respect of the custody, control and management of monies, the

<PAGE>

      Aircraft or documents authorized to be delivered under this Trust
      Agreement or under the Participation Agreement shall be exercised solely
      by Owner Trustee;

            (ii) All other rights, powers, duties and obligations conferred or
      imposed upon Owner Trustee shall be conferred or imposed upon and
      exercised or performed by Owner Trustee and such additional trustee
      jointly, except to the extent that under any Law of any jurisdiction in
      which any particular act or acts are to be performed (including the
      holding of title to the Trust Estate) Owner Trustee shall be incompetent
      or unqualified to perform such act or acts, in which event such rights,
      powers, duties and obligations shall be exercised and performed by such
      additional trustee;

            (iii) No power given to, or which it is provided hereby may be
      exercised by, any such additional trustee shall be exercised under this
      Trust Agreement by such additional trustee, except jointly with, or with
      the consent in writing of, Owner Trustee;

            (iv) No trustee under this Trust Agreement shall be personally
      liable by reason of any action or omission of any other trustee under this
      Trust Agreement;

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

            (vi) No appointment of, or action by, any additional trustee will
      relieve Owner Trustee of any of its obligations under, or otherwise affect
      any of the terms of, the Trust Indenture or affect the interests of
      Mortgagee or the Note Holders in the Trust Indenture Estate.

            (c) In case any separate trustee under this Section 9.2 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 Law, vest in and be exercised by Owner Trustee, without the
      appointment of a successor to such separate trustee.

Owner Participant, (a) no such supplement, amendment or modification shall (i)

modify or amend any indemnities in favor of Owner Participant as set forth in
Section 9 of the Participation Agreement or in the Tax Indemnity Agreement,

supplement, amendment or modification shall require Owner Participant to invest
or advance funds or shall entail any additional personal liability or the
surrender of any indemnification, claim or individual right on the part of Owner
Participant with respect to any agreement or obligation.

                  10.1.2      Delivery of Amendments and Supplements to
                        Certain Parties

            A signed copy of each amendment or supplement referred to in Section

pursuant to the terms of Section 10.1, Owner Trustee shall be entitled to

document is authorized under this Trust Agreement. If in the opinion of Owner
Trustee any such document adversely affects any right, duty, immunity or
indemnity in favor of Owner Trustee under this Trust Agreement or under any
other Owner Trustee Agreement, Owner Trustee may in its discretion decline to
execute such document unless Owner Trustee is furnished with indemnification
from Lessee or any other party upon terms and in amounts reasonably satisfactory
to Owner Trustee to protect the Trust Estate and the Owner Trustee against any
and all liabilities, costs and expenses arising out of the execution of such
documents.

            10.3  Absence of Requirements as to Form

            It shall not be necessary for any written request furnished pursuant
to Section 10.1 to specify the particular form of the proposed documents to be
executed pursuant to such Section 10.1, but it shall be sufficient if such
request shall indicate the substance thereof.

            10.4  Distribution of Documents

            Promptly after the execution by Owner Trustee of any document
entered into pursuant to Section 10.1, Owner Trustee shall mail, by certified

the validity of such document.

Indenture Supplement

            No written request pursuant to Section 10.1 shall be required to

            11.1  Termination of Trust Agreement

            This Trust Agreement and the trusts created hereby shall be of no
further force or effect upon the earlier of (a) both the final discharge of the
Trust Indenture pursuant to Section 10.01 thereof and the sale or other final
disposition by Owner Trustee of all property constituting part of the Trust
Estate and the final distribution by Owner Trustee of all monies or other
property or proceeds constituting part of the Trust Estate in accordance with
Section 4, PROVIDED, that at such time Lessee shall have fully complied with all
of the terms of the Lease and the Participation Agreement or (b) 21 years less
one day after the death of the last survivor of all of the descendants of the
grandparents of David C. Rockefeller living on the date of the earliest
execution of this Trust Agreement by any party hereto, but if this Trust
Agreement and the trusts created hereby shall be or become authorized under
applicable Law to be valid for a period commencing on the 21st anniversary of
the death of such last survivor (or, without limiting the generality of the
foregoing, if legislation shall become effective providing for the validity of
this Trust Agreement and the trusts created hereby for a period in gross
exceeding the period for which this Trust Agreement and the trusts created
hereby are hereinabove stated to extend and be valid), then this Trust Agreement
and the trusts created hereby shall not terminate under this clause (b) but
shall extend to and continue in effect, but only if such nontermination and
extension shall then be valid under applicable Law, until the day preceding such
date as the same shall, under applicable Law, cease to be valid; otherwise this
Trust Agreement and the trusts created hereby shall continue in full force and
effect in accordance with the terms hereof. Except as expressly set forth in
Section 11.2, this Trust Agreement and the trusts created hereby may not be
revoked by Owner Participant.

            11.2  Termination at Option of the Owner Participant

            Notwithstanding Section 11.1 hereof, this Agreement and trust
created hereby shall terminate and the Trust Estate shall be distributed to the
Owner Participant, and this Agreement shall be of no further force and effect,
upon the election of the Owner Participant by notice to the Owner Trustee, if
such notice shall be accompanied by the written agreement (in form and substance
satisfactory to the Owner Trustee) of the Owner Participant assuming all
obligations of the Owner Trustee under or contemplated by the Operative
Agreements or incurred by it as trustee hereunder and releasing the Owner
Trustee therefrom; provided, however, that such notice may be given only after

            11.3  Owner Participant Has No Legal Title in Trust Estate

            Owner Participant shall not have legal title to any part of the
Trust Estate. No transfer, by operation of Law or otherwise, of any right, title
and interest of Owner Participant in and to the Trust Estate under this Trust
Agreement shall operate to terminate this Trust Agreement or the trusts under
this Trust Agreement or entitle any successors or transferees of Owner
Participant to an accounting or to the transfer of legal title to any part of
the Trust Estate.

            11.4  Assignment, Sale, etc. of Aircraft

            Any assignment, sale, transfer or other conveyance of the Aircraft
by Owner Trustee made pursuant to the terms of this Trust Agreement or of the
Lease or the Participation Agreement shall bind Owner Participant and shall be
effective to transfer or convey all right, title and interest of Owner Trustee
and Owner Participant in and to the Aircraft. No purchaser or other grantee
shall be required to inquire as to the authorization, necessity, expediency or
regularity of such assignment, sale, transfer or conveyance or as to the
application of any sale or other proceeds with respect thereto by Owner Trustee.

            11.5  Trust Agreement for Benefit of Certain Parties Only

            Except for the terms of Section 10 of the Participation Agreement
incorporated in Section 8 and except as otherwise provided in Sections 4.2.5,
5.1, 6.7, 9, 10.1, 11.1 and 11.2, nothing in this Trust Agreement, whether
express or implied, shall be construed to give any person other than Owner
Trustee and Owner Participant any legal or equitable right, remedy or claim
under or in respect of this Trust Agreement; and this Trust Agreement shall be
held to be for the sole and exclusive benefit of Owner Trustee and Owner
Participant.

            11.6  Citizenship of Owner Participant

            If at any time there shall be more than one Owner Participant, then
any Owner Participant who shall cease to be a Citizen of the United States shall
have no voting or similar rights under this Trust Agreement and shall have no
right to direct, influence or limit the exercise of, or to prevent the direction
or influence of, or place any limitation on the exercise of, Owner Trustee's
authority or to remove Owner Trustee.

            11.7  Notices

            Unless otherwise expressly permitted by the terms of this Trust
Agreement, all notices, requests, demands, authorizations, directions, consents,
waivers and other communications required or permitted to be made, given,
furnished or filed under this Trust Agreement shall be in writing, shall refer

telecopy, telex or other means of electronic facsimile or telecommunication
transmission, sent by registered mail or certified mail, return receipt
requested, postage prepaid, or sent by overnight courier service, in each case
to the respective telex, telecopy or other number or address set forth for such
party in Schedule 1 to the Participation Agreement, or to such other telex,
telecopy or other number or address as each party hereto may hereafter specify

confirmed, or (b) by registered or certified mail, three Business Days after
being deposited, properly addressed, in the U.S. mail.

            11.8  Severability

            If any provision of this Trust Agreement shall be held invalid,
illegal or unenforceable in any respect in any jurisdiction, then, to the extent
permitted by Law, (a) all other provisions hereof shall remain in full force and
effect in such jurisdiction and (b) such invalidity, illegality or
unenforceability shall not affect the validity, legality or enforceability of
such provision in any other jurisdiction. If, however, any Law pursuant to which
such provisions are held invalid, illegal or unenforceable may be waived, such
Law is hereby waived by the parties hereto to the full extent permitted, to the
end that this Trust Agreement shall be deemed to be a valid and binding
agreement in all respects, enforceable in accordance with its terms.

            11.9  Waivers, Etc.

            No term or provision hereof may be changed, waived, discharged or
terminated orally, but only by an instrument in writing entered into in
compliance with the terms of Section 10; and any waiver of the terms hereof
shall be effective only in the specific instance and for the specific purpose
given.

            11.10 Counterparts

            This Trust Agreement and any amendments, waivers, consents or
supplements hereto may be executed in any number of counterparts, each of which
when so executed shall be deemed to be an original, and all of which
counterparts, taken together, shall constitute one and the same instrument.

            11.11 Binding Effect, Etc.

            All covenants and agreements contained in this Trust Agreement shall
be binding upon, and inure to the benefit of, Owner Trustee and its successors
and assigns, and Owner Participant and its successors and, to the extent
permitted by Section 8, assigns. Any request, notice, direction, consent, waiver
or other instrument or action by Owner Participant shall bind its successors and
assigns.

            11.12 Headings; References

            The headings and the table of contents used in this Trust Agreement
are for convenience of reference only and shall not define or limit any of the

            11.14 Governing Law

            THIS TRUST AGREEMENT SHALL IN ALL RESPECTS BE GOVERNED BY THE LAWS
OF THE STATE OF UTAH, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND

            SECTION 12. CERTAIN LIMITATIONS

            12.1  Limitations on Control; Exceptions

            (a) Notwithstanding any other provision of this Agreement, at any
time that the Owner Participant is not a citizen of the United States as defined
in 49 U.S.C. Section 40102(a)(15) (a "Citizen"), the Owner Participant shall
have no rights or powers to direct, influence, or control the Owner Trustee in
the performance of the Owner Trustee's duties under this Agreement in connection
with matters involving the ownership and operation of the Aircraft by the Owner
Trustee. In all matters involving the ownership and operation of the Aircraft by
the Owner Trustee, the Owner Trustee shall have absolute and complete discretion
in connection therewith and shall be free of any kind of influence or control
whatsoever by the Owner Participant at any time that the Owner Participant is
not a Citizen, and the Owner Trustee shall exercise its duties under this
Agreement in connection with all matters involving the ownership and operation
of the Aircraft by the Owner Trustee as it, in its discretion, shall deem
necessary to protect the interests of the United States, notwithstanding any
countervailing interest of any foreign power that, or whose citizens, may have a
direct or indirect interest in the Owner Participant and any such action by the
Owner Trustee shall not be considered malfeasance or in breach of any obligation
that the Owner Trustee might otherwise have to the Owner Participant; PROVIDED,
however, that subject to the foregoing limitations, the Owner Trustee shall
exercise its discretion in all matters involving the ownership and operation of
the Aircraft by the Owner Trustee with due regard for the interests of the Owner
Participant. In exercising any of its rights and duties under this Agreement in
connection with matters that may arise not relating to the ownership and
operation of the Aircraft, the Owner Trustee shall be permitted to seek the
advice of the Owner Participant before taking, or refraining from taking, any
action with respect thereto. The Owner Trustee shall notify the Owner
Participant of its exercise of rights and duties under the Trust Agreement in
connection with matters involving the ownership and operation of the Aircraft by
the Owner Trustee.

            (b) At any time the Owner Participant is not a Citizen of the United
States, the Owner Participant shall have no rights or powers to remove the Owner
Trustee except with cause, including without limitation for gross negligence,
willful misconduct, misfeasance, malfeasance, or nonfeasance in, or material
breach of, its duties under the Trust Agreement or applicable law.

            (c) Subject to the requirements of subsection (a) above, the Owner
Trustee will not, without the prior written consent of the Owner Participant,

<PAGE>

(a) sell, mortgage, pledge, or otherwise dispose of the Aircraft or other assets
held in the trust estate relating thereto, except as otherwise provided for in
this Agreement, or (b) amend the Lease or other Operative Documents or give any
consents thereunder.

            (d) Notwithstanding any other provision of this Section 12.1, the
Owner Participant shall be entitled to receive from the Owner Trustee, or
otherwise, and the Owner Trustee shall not be entitled to retain, all rent,
payment, and insurance proceeds, and other payments of any kind or nature
whatsoever payable to the Owner Participant pursuant to the Trust Agreement or
any other Operative Agreements in the same manner as if the power of management
and control had not been transferred to the Owner Trustee as provided in this
Section 12.1.

            (e) The purpose of this Section 12.1 is to give the Owner Trustee
the power to manage and control the Aircraft with respect to matters involving
the ownership and operation of the Aircraft by the Owner Trustee so as to assure
that (a) the Aircraft shall be controlled with respect to such matters by a
Citizen of the United States, (b) if the Owner Participant is not a Citizen of
the United States, the Owner Participant shall have no power to influence or
control the exercise of the Owner Trustee's authority with respect to such
matters, and (c) the Owner Trustee shall be able to give the affidavit required
by Section 47.7(c)(2)(iii) of the Federal Aviation Regulations, 14 C.F.R.
47.7(c)(2)(iii). The restrictions and requirements of this Section 12.1 shall be
construed in furtherance of such purpose.

            (f) If persons who are not "citizens of the United States" as
defined in 49 U.S.C. section 40102(a)(15) or resident aliens have the power to
direct or remove the Owner Trustee, either directly or indirectly through the
control of another person, those persons together may not have more than 25% of
the aggregate power to direct or remove the Owner Trustee. Nothing in this
paragraph prevents those Persons from having more than 25% of the beneficial
interest in the Trust Estate.
