performed in

                                      3-1

condition, business or operations of Lessee or its ability to perform any of its
obligations under any of the Lease Documents to which it is a party.

              ---------------------
this Lease with the FAA, and the filing of any Uniform Commercial Code financing
statements required (and continuation statements at periodic intervals), no
further filing or recording of this Lease or of any other document (including
any financing statement under Article 9 of the Uniform Commercial Code) and no
further action, are necessary or desirable under the laws of the United States
of America in order to (A) fully protect and establish Lessor's title to, and
interest in, and property rights with respect to the Aircraft as against Lessee
or any third party claiming through Lessee and to ensure that the property
rights of Lessor therein will have priority in all respects over the claims of
all creditors of Lessee, or (B) ensure the validity, effectiveness and

cause Lessee not to be a Certificated Air Carrier.

                -----------
and covenants and agrees that at all time during the Term it shall remain, a

Rate on any part of any installment of Basic Rent not paid when due for any
period for which the same shall be overdue and, to the extent permitted by
Applicable Law, on any payment of Supplemental Rent not paid when due for the
period until the same shall be paid.

     SECTION 8. USE OPERATION AND MAINTENANCE.
                -----------------------------

          8.1  General. Unless otherwise provided herein, Lessee, at its own
               -------
cost and expense, shall service, repair, maintain and overhaul or cause the same
to be done to the Airframe and each Engine under the Maintenance Program (as
defined in Section 8.3) for so long as the Airframe is operated and leased
hereunder by Lessee in the same manner and with the same care as used by Lessee
with similar aircraft and engines. By way of expansion and not in limitation of
the foregoing, Lessee agrees to (i) keep the Airframe and each Engine in as good
operating condition as when delivered to Lessee hereunder, ordinary wear and
tear excepted, (ii) keep the Aircraft in such condition as is necessary to
enable the airworthiness certification of the Aircraft to be maintained in good
standing at all times under the Federal Aviation Act, (iii) maintain the Manuals
and Technical Records in the English language in accordance with such
Maintenance Program and in a manner acceptable to the FAA and (iv) cause the
Aircraft to be maintained in a manner which will not discriminate against the
Aircraft compared with other Boeing 727 aircraft owned or leased by Lessee.

          8.2  Operation and Use.
               -----------------

               (a) Lessee agrees not to operate or locate the Airframe or any
Engine, or suffer the Airframe or any Engine to be operated or located, in any
area (i) excluded from coverage by any insurance policy required to be
maintained hereunder with respect to the Airframe or Engines or (ii) in any
recognized or, in Lessor's reasonable judgment, threatened area of hostilities
unless fully covered by war risk insurance meeting the terms of Section 11
hereof, except in the case of a requisition by the United States government,
where Lessee obtains indemnity from the United States government against the
risks and in the amounts required by Section 11 hereof covering such area,
including insurance provided under Title XIII of the Federal Aviation Act.
Lessee agrees not to operate the Aircraft, or suffer the Aircraft to be operated
during the Term (x) unless the Aircraft is covered by insurance as required by
the provisions of Section 11 hereof or (y) contrary to the terms of such
insurance as required by the provisions of Section 11 hereof.

               (b) Lessee agrees not to (i) operate the Aircraft or permit the
Aircraft to be operated during the Term except in a passenger configuration, in
commercial or other operations for which Lessee is duly authorized by the FAA or
the appropriate foreign authority, provided that Lessee shall be permitted to
transport cargo and mail in the cargo compartments of the Aircraft or (ii) use
or permit the Aircraft to be used for a purpose for which the Aircraft is not
designed or reasonably suitable. Lessee will not permit the Airframe or any
Engine to be maintained, used or operated during the

                                      8-1

<PAGE>
Term in knowing violation of any Applicable Law, or contrary to any
manufacturer's operating manuals or instructions.

          8.3  Maintenance in General. Lessee agrees that it alone has the
               ----------------------
obligation to maintain and repair the Airframe and Engines in accordance with a
maintenance program which meets the FAA requirements for United States
commercial airline operations under Part 121 of the Federal Aviation Regulations
and which is approved or accepted by the appropriate FAA Flight Standards Air
Carrier District Office having responsibility for monitoring Lessee's operation
and maintenance of the Aircraft, and meets the non-discrimination requirements
set forth in Section 8.1 hereof (the "Maintenance Program"), so as to keep the
Aircraft in as good a condition during the Term as on the Delivery Date and
until the Aircraft is redelivered to Lessor pursuant to Section 9 hereof,
ordinary wear and tear excepted. Included within the obligation of maintenance
and repair is the obligation and affirmative undertaking by Lessee to replace
from time to time all worn or defective Parts to the extent required to cause
the Aircraft to be in an airworthy condition in all respects and to be covered
by an effective Standard Certificate of Airworthiness at all times except during
those periods when the Aircraft is undergoing maintenance or repairs as required
by this Lease.

          8.4  Specific Items of Maintenance. Lessee agrees that maintenance and
               -----------------------------
repairs shall include, but shall not be limited to, the following specific
items:

               (a) to perform or have performed in accordance with Section 8.3
all routine maintenance work, including on-line maintenance on the Aircraft, and
to ensure that all such maintenance shall be in accordance with the regulations
and directives of the FAA or other government authority having jurisdiction over
Lessee's operations. Lessee shall have all maintenance and repairs performed at
Lessee's maintenance facilities or at other FAA Repair Stations selected by
Lessee;

               (b) to correct promptly and diligently any deficiencies revealed
at any time by any inspection of Lessor which under the Maintenance Program
require proper repair, replacement, overhaul and adjustment;

               (c) to maintain all Aircraft documentation, including, without
limitation, the Manuals and Technical Records, in compliance with FAA
regulations and in up-to-date status, and to make these available for review by
Lessor on reasonable notice at Lessee's principal maintenance base;

               (d) If required by FAA regulations, Lessee shall notify Lessor
     promptly of any modifications or configuration changes to the Airframe
     which would

                                      8-2
<PAGE>

     have a material change to the detail specification and/or the manuals
     relating to the Airframe (such as flight, operations and maintenance).

          8.5  Parts.
               -----

               (a) Unless the Airframe or an Engine has suffered Total Loss,
Lessee, at its own cost and expense, will during the Term promptly replace all
Parts that may from time to time become worn out, lost, stolen, destroyed,
seized, confiscated, damaged beyond repair or permanently rendered unfit for use
for any reason whatsoever. In addition, in the ordinary course of maintenance,
service, repair, overhaul or testing, Lessee may remove any Parts, whether or
not worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond
repair or permanently rendered unfit for use, provided that Lessee shall replace
such Parts as promptly as practicable with replacement Parts. All replacement
Parts shall be made by the same manufacturer and of the same model number and
modification status, or shall be FAA-approved substitutes normally used by
Lessee. All replacement Parts shall be free and clear of all Liens except
Permitted Liens and shall be in as good operating condition as, and shall have a
value, utility, and useful life at least equal to, the Parts replaced assuming
such replaced Parts were in the condition and repair required to be maintained
by the terms hereof.

               (b) All Parts at any time removed from the Airframe or any Engine
shall remain the property of Lessor and subject to this Lease, no matter where
located, until such time as such Parts shall be replaced by Parts that have been
incorporated or installed in or attached to such Airframe or Engine and that
meet the requirements for replacement Parts specified in clause (a) of this
Section 8.5. Immediately upon any replacement Part becoming incorporated or
installed in or attached to such Airframe or Engine as provided in clause (a)
hereof, without further act, (i) title to such replacement Part shall thereupon
vest in Lessor, (ii) such replacement Part shall become subject to this Lease
and be deemed part of such Airframe or Engine, as the case may be, for all
purposes hereof to the same extent as the Parts originally incorporated or
installed in or attached to such Airframe or Engine, and (iii) title to the
replaced Part shall thereupon vest in Lessee, free and clear of all rights of
Lessor and shall no longer be deemed a Part hereunder.

               (c) Title to all Parts incorporated or installed in or attached
or added to the Airframe or any Engine as the result of any alteration,
modification or addition effected by Lessee shall, without further act and
except as otherwise provided Section 8.6(c) hereof, vest in Lessor and become
subject to this Lease.

               (d) Notwithstanding the foregoing provisions of this Section 8.5.
     Lessor agrees that so long as no Event of Default shall have occurred and
     be continuing,

                                      8-3
<PAGE>

     Lessee may, at any time during the Term. remove any Part of the Aircraft
     without replacement, provided that (i) such Part is in addition to. and not
     in replacement or substitution for, any Part originally incorporated or
     installed in or attached to the Aircraft at the Delivery Date hereunder or
     any Part in replacement of, or substitution for, any such originally
     incorporated or installed or attached Part, (ii) such Part is not required
     to be incorporated or installed in or attached or added to the Aircraft
     pursuant to the terms of this Section 5 and (iii) such Part can be removed
     from the Aircraft without diminishing or impairing the value, utility,
     condition or airworthiness which the Aircraft would have had at such time
     had such alteration, modification or addition not occurred. Upon the
     removal by Lessee of any such Part as provided in the preceding sentence,
     title thereto shall, without further act, vest in Lessee and such Part
     shall no longer be deemed part of the Aircraft (such a part is herein
     called a "Removable Part"). Lessee, at its sole expense, shall repair any
     damage to the Aircraft resulting from any such removal. Any Part not
     removed by Lessee as above provided prior to the return of the Aircraft to
     Lessor hereunder, whether pursuant to Section 9, Section 14 or otherwise,
     shall remain the property of Lessor. If any Removable Part is (x) owned by
     any third party and leased to Lessee or installed on the Aircraft under
     license from Lessee, (y) sold to Lessee subject to a conditional sales
     contract or other security interest or (z) leased to Lessee pursuant to a
     lease which is subject to a security interest in favor of any third party,
     then Lessor will not acquire or claim, as against such lessor, conditional
     vendor or secured party, any right, title or interest in any such Removable
     Part as the result of such Removable Part being installed in the Aircraft;
     provided, however, (xx) that Lessor's inability to so acquire or claim is
     subject to the express condition that such lessor, licensee, conditional
     vendor or secured party shall not acquire or claim, as against Lessor, any
     right, title or interest in the Aircraft, or any Part other than its
     interest in such Removable Part by reason of such Removable Part being
     installed thereon, and (yy) that any Removable Part not removed by Lessee
     within sixty (60) days after an Event of Default, shall, at such time,
     become the property of Lessor and be subject to this Lease.

          8.6  Airworthiness Directives.
               -------------------------

               (a)  During the Term hereof Lessee agrees at its sole cost and
expense to comply with any airworthiness directive, the Federal Aviation
Regulations and Special Federal Aviation Regulations, manufacturers' mandatory
service bulletins or any other mandatory regulation, directive or instruction
("Airworthiness Directive") which the FAA may from time to time issue and which
becomes due during the Term in order to meet the requirements of Applicable Law
related to the public transport of passengers and/or cargo by aircraft;
provided, however. that nothing in this Lease shall be deemed to require Lessee
or Lessor to bring the Aircraft into compliance with the Stage 3 noise standards
set forth in Part 36 of the Federal Aviation Regulations (14 C.F.R. Part 36).
All Airworthiness Directives shall be accomplished in accordance with all
applicable

                                      8-4
<PAGE>

bulletins and manuals published by the manufacturer of the Airframe or Engines
or Parts.


               (b) Lessor shall hold title to any Parts included in a new system
installed on the Aircraft pursuant to an Airworthiness Directive which is
required by such Airworthiness Directive to be installed during the Term.

               (c) If Lessee would not normally perform an Airworthiness
Directive, or such other modification desired by Lessor, the terms of which
permit performance after the end of the Term, and Lessor requests Lessee, in
writing, to perform such Airworthiness Directive or modification, Lessee shall
perform such Airworthiness Directive or modification; provided, however, that
Lessee's obligations to perform such Airworthiness Directive or modification
pursuant to this Section 8.6(c) shall be subject to availability of the
necessary material, labor and facilities and shall not unreasonably interfere
with, or delay, Lessee's operation and are of the Aircraft. In the event Lessee
is unable to perform an Airworthiness Directive or modification requested by
Lessor under this Section 8.6(c) because of the lack of availability of
materials, labor or facilities or such performance will unreasonably interfere
with or delay Lessee's operation and use (including redelivery) of the Aircraft,
Lessee will cooperate with, and assist Lessor in the accomplishment of such work
by a FAA Repair Station. The costs of such performance shall be borne solely by
Lessor and shall be equal to the sum of material costs and the associated Direct
Labor Rate cost or labor costs, as the case may be.

          8.7  Maintenance Agencies. To the extent that Lessee intends that any
               --------------------
of the activities to be performed pursuant to this Section 8 with respect to the
Airframe or Engines are to be performed by any Person other than Lessee and not
pursuant to the Maintenance Program, such maintenance shall be performed to an
FAA-approved standard.

          8.8  Corrosion Control. Lessee shall carry out such work as may be
               -----------------
required for the control of corrosion, including, without limitation, periodic
inspections for penetration of fuel tanks, periodic inspections and clean-up
under galleys, forward and aft cargo pit areas and lavatories, periodic
treatment of all mild and moderate corrosion and correcting of all severe or
exfoliated corrosion, in accordance with the Maintenance Program.

          8.9  Modifications.
               -------------

               (a)  Lessee, at its own expense. may from time to time make such
alterations and modifications in and additions to the Airframe or any Engine as
Lessee

                                      8-5
<PAGE>

may deem desirable in the proper conduct of its business, including without
limitation, removal of Parts which Lessee deems no longer suitable or
appropriate for use in the Airframe or such Engine; provided, that no such
alteration, modification or addition shall diminish the value or utility of the
Airframe or such Engine, or impair the condition or airworthiness thereof, below
the value, utility, condition and airworthiness thereof prior to such
alteration, modification or addition assuming the Airframe or such Engine met
the requirements of this Lease prior to such alteration, modification or
addition. Notwithstanding the foregoing, Lessee shall not, without Lessor's
prior written consent, make any major modifications, alterations or additions to
the Aircraft, i.e., those costing in excess of $400,000. For the purposes of
              ----
this section "major modifications" shall exclude modifications required by
Applicable Law and modifications made by Lessee to standardize the Aircraft to
Lessee's fleet or modifications otherwise required by the terms of this Lease,
but shall include (1) changes relating to the Aircraft's structure or
performance and (2) changes which could adversely affect spare parts
interchangeability or replaceability. All major modifications shall be
accomplished by at Lessee's expense.

               (b) If the Aircraft is not in Lessee's standard fleet
configuration, Lessor may require Lessee, at Lessee's sole expense, to remove
all modifications accomplished by Lessee and to reconstruct the modified areas
to Lessee's standard fleet configuration or to their original configuration in a
good and workmanlike manner prior to return of the Aircraft to Lessor.

               (c) NOTWITHSTANDING ANY OTHER PROVISION OF THIS LEASE, NO
MODIFICATION SHALL BE MADE WHICH HAS THE EFFECT OF DECREASING THE UTILITY OR
VALUE OF THE AIRCRAFT OR ADVERSELY AFFECTS ITS AIRWORTHINESS OR USE FOR
TRANSPORTING PASSENGERS IN COMMERCIAL SERVICE.

          8.10 Possession. Lessee shall not sublease the Aircraft or otherwise
               ----------
in any manner deliver, relinquish or transfer possession of the Airframe or any
Engine to any Person or install any Engine, or permit any Engine to be
installed, on any airframe other than the Airframe, during the Term, without the
prior written consent of Lessor; provided, however, that so long as Lessee shall
comply with the provisions of Section 11 hereof Lessee may, without the prior
written consent of Lessor:

               (a) enter into a contract, commonly referred to in the U.S.
airline industry as a "wet lease," under which Lessee has operational control of
the Aircraft in the ordinary course of Lessee's business (which shall not be
considered a transfer of possession hereunder), provided that Lessee's
obligations under this Lease shall continue in full force and effect
notwithstanding any such "wet lease" contract;

                                      8-6
<PAGE>

               (b) deliver possession of the Airframe or an Engine to the
manufacturer thereof or to a FAA Repair Station for testing or other similar
purposes or for service, repair, maintenance or overhaul work on the Airframe or
Engines or for alterations or modifications in or additions to the Airframe or
Engines, to the extent required or permitted by the terms of this Lease;

               (c) subject any Engine to normal interchange or pooling
agreements or arrangements, in each case customary in the United States airline
industry applicable to other similar aircraft and engines operated by Lessee and
entered into by Lessee in the ordinary course of its business with any
Certificated Air Carrier; provided that (A) no such agreement or arrangement
contemplates or requires the transfer of title to such Engine, and (B) if
Lessor's title to any Engine shall be divested under any such agreement or
arrangement, such divestiture shall be deemed to be a Total Loss with respect to
such Engine and Lessee shall comply with Section 12.2 hereof in respect of such
Engine;

               (d) install an Engine on an airframe owned by Lessee free and
clear of all Liens, except (i) Permitted Liens, and (ii) those which apply only
to the engines (other than Engines), appliances, parts, instruments,
appurtenances, accessories, furnishings and other equipment (other than Parts)
installed on such airframe (but not to the airframe as an entirety), and (C)
those created by the rights of other Certificated Air Carriers under normal
interchange or pooling agreements or arrangements customary in the airline
industry which do not contemplate, permit or require the transfer of title to
such airframe or engines installed thereon;

               (e) install an Engine on an airframe leased to Lessee or
purchased by Lessee subject to a conditional sale or other security agreement;
provided that (i) such Airframe is free and clear of all liens except (A) the
rights of the parties to the lease, conditional sale or other security agreement
and (B) Liens of the type permitted by clause (d) above, and (ii) such lease,
conditional sale or other security agreement effectively provides that such
Engine shall not become subject to the Lien of such lease, conditional sale or
other security agreement, notwithstanding the installation thereof on such
airframe;

               (f) install an Engine on an airframe owned by Lessee, leased by
Lessee or purchased by Lessee subject to a conditional sale or other security
agreement under circumstances where neither clause (d) nor clause (e) above is
applicable; provided that any divestiture of Lessor's title to such Engine
resulting from such installation shall be deemed a Total Loss with respect to
such Engines and Lessee shall comply with Section 12.2 hereof;

                                      8-7
<PAGE>

               (g) transfer possession of the Airframe or any Engine to the
United States of America or any instrumentality thereof under to the Civil
Reserve Air Fleet Program authorized by 10 U.S.C. (S)9511, et seq., or any
                                                           ------
substantially similar program provided such transfer of possession does not
exceed the Basic Term. If an Event of Default occurs under this Lease and Lessor
elects to pursue its remedies under Section 14 to terminate this Lease and
repossess the Aircraft (or Engine), Lessor will so notify the United States
Government by sending a written communication to:
Headquarters, AMC Contracting Office - XOKA, Scott Air Force Base, Illinois
62225-5007.

               (h) transfer possession of the Airframe or any Engine to the
United States of America for a period that does not continue beyond the end of
the Basic Term when required by Applicable Law; provided that the rights of any
transferee who receives possession by reason of a transfer permitted by this
Section 8.10 (other than by a transfer of an Engine which is deemed a Total Loss
if substitution is being duly effected under Section 12.2 hereof) shall be
subject and subordinate to all the terms of this Lease.

     In the event Lessor shall have received from a lessor or secured party of
any airframe leased to Lessee or purchased by Lessee subject to a conditional
sale or other security agreement, a written agreement which provides that such
lessor or secured party under such agreement shall not acquire or claim any
right, title or interest in any Engine, and such lease or conditional sale or
other security agreement covering such airframe also covers an engine or engines
owned by such lessor under such lease or subject to a security interest in favor
of such secured party under such conditional sale or other security agreement,
Lessor hereby agrees for the benefit of such lessor or secured party that Lessor
will not acquire or claim, as against such lessor or secured party, any right,
title or interest in any such engine as the result of such engine being
installed on the Airframe at any time while such engine is owned by such lessor
or is subject to such conditional sale or other security agreement or security
interest in favor of such secured party. The existence of a clause substantially
similar to the foregoing in such lease, conditional sale or other security
agreement whereby the lessor or secured party, as the case may be, is
substituted for Lessor, shall suffice as the required written agreement.

               (i) Notwithstanding any transfers of possession of Engines
permitted pursuant to this Section 8.10, Lessee shall at all times during the
Term of this Lease remain fully liable and obligated to perform all of the terms
of this Lease to the same extent as if such transfer had not occurred.

          8.11 Reports. Lessee shall furnish to Lessor, on an annual basis, the
               -------
the Hours/Cycles operated for Airframe. Such reports shall be furnished no later
than 120 days following the end of each calendar year.

                                      8-8

          8.12 Right to Inspect.
               ----------------

               (a) Lessor and its agents shall have the right to inspect the
Aircraft at any reasonable time, upon giving Lessee reasonable notice, to
ascertain the condition of the Aircraft and to satisfy Lessor that the Aircraft
is being repaired and maintained in accordance with the requirements of this
Lease. Lessee shall, at the request of Lessor, provide Lessor with such
information concerning the location of the Aircraft as may be necessary to
facilitate such inspection and shall permit Lessor or its duly authorized
representative to be present during any overhaul or the performance of any major
scheduled maintenance check of the Aircraft; provided that Lessor inspections
conducted pursuant to this Section 8.12 shall not unreasonably interfere with,
or delay Lessee's operation and use of the Aircraft, any Engine or Part. The
cost of the inspection or survey shall be paid by Lessee if the Aircraft, or any
part thereof, is not in the condition required by this Lease but shall otherwise
be paid by Lessor. All repairs which shall be shown by the inspection or survey
to be required shall be made at Lessee's expense in accordance with the
Maintenance Program. All required repairs shall be performed as soon as
practicable thereafter. In the event of a dispute between Lessor and Lessee as
to the proper performance by Lessee of the repairs required hereunder, the
decision of the manufacturer of the Airframe, Engine or Part, as the case may
be, shall control subject always to Lessee's need to comply with Applicable
Laws, including any rules, orders or directions of FAA or its duly authorized
inspectors. The non-prevailing party shall be responsible for payment of all
expenses of such manufacturer incurred in connection with the rendering of its
decision. Lessor shall have no duty to make any such inspection and shall not
incur any liability or obligation by reason of not making such inspection.

               (b) Lessee shall make available to Lessor for its review (i) such
records as Lessee may have in its possession which Lessor may request pursuant
to Lessor's inspection rights set forth in subsection (a), above; (ii) such
other written communications with the FAA or any manufacturer as it may have in
its possession relating to defects or malfunctions of the Aircraft or Parts or
other matters; and (iii) Lessee's most recent FAA-approved operations
specifications, including any amendments or additions made thereto. All such
records shall be made available for inspection at Lessee's principal maintenance
facility and shall be deemed confidential. Lessor agrees to protect the
confidentiality of such records and to not disclose the same to any person,
except as otherwise required by law, without first obtaining Lessee's written
approval.

          8.13  Repairs. Any repair to the Aircraft accomplished during the Term
                -------
shall be accomplished where applicable pursuant to the appropriate
manufacturer's repair manual instructions or the Maintenance Program. Lessee
shall have all repairs accomplished on the Aircraft at Lessee's maintenance
facilities or by an FAA Repair Station, and such repairs shall be accomplished
with no less skill and care than repairs

                                      8-9
<PAGE>

made on Lessee's other owned or operated Boeing 727-200 series aircraft. Such
repairs shall be made in a workmanlike manner so as to keep the Aircraft at all
times in the condition required by the Maintenance Program.

          8.14 Aircraft Records. Lessee shall maintain all records (including
               ----------------
all Manuals and Technical Records) during the Term relating to the service,
inspection, maintenance, modification, repair and overhaul of the Airframe,
Engines and Parts installed therein which records will at all times be kept
current and up-to-date in order to facilitate Lessor's ability to periodically
inspect the Aircraft, monitor the maintenance of the Aircraft during the Term
and to facilitate the sale or release of the Aircraft to a third party at the
end of the Term.

          8.15 Lessor's Disclaimer. Notwithstanding the rights of Lessor to
               -------------------
inspect the Aircraft and receive reports on its condition and maintenance
contained in this Section 8 and elsewhere in this Lease, Lessor shall have no
obligation to any Person to ensure that Lessee maintains the Aircraft in an
airworthy condition or otherwise in accordance with the terms of this Lease.

  SECTION 9. RETURN OF AIRCRAFT
             ------------------

           9.1   Return Location. At the end of the Term or upon termination of
                 ---------------
this Lease pursuant to Section 14 hereof, Lessee shall return the Airframe and
Engines to Lessor at Lessee's principal maintenance facility at the Indianapolis
International Airport, Indianapolis, Indiana, or at such other location within
the continental United States as shall be agreed to by the parties (the "Return
Location"). The Aircraft at the time of its return shall be free and clear of
all Liens other than Lessor's Liens. At the time of return of the Aircraft to
Lessor, and provided Lessee is in compliance with the terms of this Lease,
Lessor and Lessee shall execute a Technical Acceptance Certificate (Return)
substantially in the form of Exhibit E. The payment of all costs, fees and taxes
related to the positioning of the Aircraft at the Return Location shall be for
the account of Lessee.

           9.2   Return of Other Engines. In the event any engine not owned by
                 -----------------------
Lessor shall be returned with the Airframe, it shall be a Replacement Engine,
and Lessee will, at its own expense and concurrently with such return, furnish
Lessor with a full warranty bill of sale, in form and substance satisfactory to
Lessor, with respect to each such Replacement Engine and shall provide such
other documents and instruments, opinions of counsel, and shall take such other
actions as Lessor may reasonably request in order that title to such Replacement
Engine shall be duly and properly vest in Lessor. Upon passage of title to
Lessor such Replacement Engine shall be deemed to be an Engine for all purposes
hereof and thereupon Lessor will transfer to Lessee, without recourse or
warranty except a warranty of tide excluding Lessor's Liens, all of Lessor's
right, title and interest in and to an Engine not installed on such Airframe at
the time of the return thereof.

           9.3   Condition of Aircraft. The Aircraft at the time of the return
                 ---------------------
to Lessor shall have been maintained and repaired in accordance with the
Maintenance Program and this Lease, and shall meet the following requirements:

                 (a)   Operating Condition. The Aircraft shall be in at least as
                       -------------------
good operating condition as on the Delivery Date, ordinary wear and tear from
normal airline passenger operations excepted.

                 (b)   Cleanliness Standards. The Aircraft shall be clean by
                       ---------------------
United States commercial airline standards.

                 (c)   Certificate of Airworthiness. The Aircraft shall have,
                       ----------------------------
and be in compliance with a current valid Standard Certificate of Airworthiness
issued by the FAA without any corrections, repairs, modifications, alterations
or overhauls having to be
                                      9-1
<PAGE>

performed by Lessor to meet such standards and rules, and shall comply with the
then current provisions of Part 121 of the Federal Aviation Regulations.

                 (d)   Compliance with Governmental Requirements. The Aircraft
                       -----------------------------------------
shall be in compliance with all Airworthiness Directives affecting the Aircraft
and requiring performance during the Term. In the event Lessee has obtained a
waiver or deviation from the FAA suspending the need of having to comply with
any such Airworthiness Directives, which waiver or deviation is unique to the
Aircraft or Lessee's operation and use thereof and not of general, industry-wide
application, Lessee shall, irrespective of such waiver or deviation, fully
comply with all such Airworthiness Directive prior to the return of the Aircraft
to Lessor as if such waiver or deviation did not exist; provided, however, that
Lessee's obligations under this Section 9.3(d) shall be limited to the extent
that the aforesaid compliance cannot be accomplished because the materials
necessary to comply with or complete such Airworthiness Directive do not exist
in the marketplace or there is no accepted, industry-wide method for compliance
with such Airworthiness Directive and such conditions continue for a period of
six (6) months following the end of the Term. For the avoidance of doubt, should
required materials or a method of compliance become available prior to the end
of such six-month period, Lessee at its own expense shall either bring the
Aircraft into compliance with the Airworthiness Directive or pay Lessor the cost
thereof.

                 (e)   Deferred Maintenance. The Aircraft shall have had
                       --------------------
accomplished thereon all outstanding deferred maintenance items and any
discrepancies indicated by the operational check flight conducted pursuant to
Section 9.12. Items deferred because of maintenance concessions (i.e., an
exemption to operate beyond the normal limits by monitoring) shall be brought
up-to-date as if such maintenance concessions or exemptions did not exist.

                 (f)   Corrosion Treatment. The Aircraft shall have been
                       -------------------
maintained by cleaning and treating of all mild corrosion and correcting of all
moderate and severe or exfoliated corrosion in accordance with the Lessee's
Maintenance Program.

                 (g)   Configuration and Condition. The Aircraft shall be
                       ---------------------------
returned having the same configuration and in the same or better condition with
all Parts installed therein as on the Delivery Date, excepting only
modifications, additions, replacements and substitution of Parts as may have
been properly made by Lessee pursuant to Section 8 and as specifically otherwise
set forth in this Section 9. At Lessor's request, and to the extent available,
Lessee shall provide Lessor with the last six reliability reports for its fleet
of Boeing 727-200 Aircraft as provided to the FAA.

                                      9-2
<PAGE>

           9.4   Specific Items. With respect to the Aircraft, the following
                 --------------
items of this Section 9.4 shall be in the following general condition or, to the
extent addressed in the Maintenance Program or maintenance procedures, in the
condition required by such manual or procedures.

The Aircraft shall:

   (i)     have installed the full complement of Engines and other equipment,
           Parts and accessories as would remain installed on such aircraft if
           the Aircraft were to remain in Lessee's service other than removal of
           components pursuant to Section 8.5(d), and shall be in a condition
           suitable for operation in commercial service;

  (ii)     comply with the Maintenance Program;

 (iii)     be in compliance with all outstanding Airworthiness Directives
           affecting the Aircraft issued by the FAA or other regulatory
           authority having jurisdiction over the Aircraft;

  (iv)     be free of fuel leaks;

   (v)     have been inspected and treated with respect to corrosion, in
           accordance with the Maintenance Program, and shall be substantially
           free from corrosion or shall be adequately treated and an approved
           corrosion prevention program shall be in operation; and

  (vi)     be free from all fuel tank contamination and corrosion.


           9.5   Condition of Airframe. The Airframe at the time of its return
                 ---------------------
to Lessor shall meet the requirements set forth below, all at Lessee's expense,
except as otherwise provided herein:

                 (a)   At the end of the Term, Lessee shall have performed
immediately prior to redelivery to Lessor a "C" check, including all phases and
multiples in accordance with the Maintenance Program, and will have corrected
any deficiencies revealed during such check and all "Deferred Maintenance" items
pursuant to Section 9.3(e);

                 (b)   The cockpit shall be cleaned. Placards shall be replaced
if required by the Maintenance Program. Lessee shall insure that any items which
are


                                      9-3
<PAGE>

reasonably found to be defective in the Aircraft's interior will be replaced
or repaired in accordance with the Maintenance Program;

                 (c)   To the extent required by the Maintenance Program, Lessee
will permanently repair the fuselage, including but not limited to (i) dents,
abrasions, and scab patches; and (ii) loose or pulled rivets, impact damage to
the Aircraft caused by ground handling equipment or impact damage caused by
foreign objects during the Term.

                 (d)   Except as otherwise provided in this Section 9, all Parts
shall be serviceable in accordance with FAA standards.

                 (e)   At the time of return, the time remaining to the next
Major Structural Inspection ("MSS") under the Maintenance Program, expressed as
a percentage of the allowable interval between such inspections, will not be
less than the time remaining as of the Delivery Date as recorded in the
Technical Acceptance Certificate (delivery) (exhibit D), provided, however, that
the Airframe shall have at least one hundred (100) Hours remaining to the next
MSI. Subject to the minimum Hour limitation set forth in the immediately
preceding sentence, Lessor will accept the Airframe with less than the indicated
percentage of allowable interval between the MSIs subject to the Return
Condition Adjustment provided for in Section 9.8.

                 (f)   The landing gear and other time-controlled components
shall be returned with the same times remaining until the next inspection or
removal as when delivered to Lessee, provided, however, that such equipment
shall have at least one hundred (100) Hours or Cycles (whichever is the
applicable and the most limiting standard) remaining until the next inspection
or removal. Subject to the Minimum Hour/Cycle limitation set forth in the
immediately preceding sentence, any deviation from the foregoing requirement
will be accepted by Lessor subject to the Return Condition Adjustment provided
for in Section 9.8. With respect to the landing gear only, the time remaining as
of the Delivery Date is recorded in the Technical Acceptance Certificate
(Delivery). With respect to the other time or calendar-controlled components
(other than Engines, landing gear and the APU) the total times, and actual times
remaining until the next limiting inspection/overhaul as of the Delivery Date
shall be those recorded in Items B-12 and/or B-14 of the Manuals and Technical
Records listed in Exhibit C.

           9.6   APU and Engines. Each Engine and Auxiliary Power Unit ("APU")
                 ---------------
shall be maintained in an "On Condition" program. On return of the Aircraft, the
APU shall be in operating condition within manufacturer's limits. Each Engine
shall be in the same aggregate Cycle/Hour configuration and exhaust gas
temperature ("EGT") margins on the return thereof as when accepted by Lessee on
the date of its delivery to Lessee. In order to determine the aggregate
Cycle/Hour configuration and EGT margin of each Engine as of such date, with
respect to the two (2) Engines having manufacturer's serial numbers 688224 and
688226, the parties shall use the data contained in paragraphs 5 and 6 of
Schedule 1 to the Technical Acceptance Certificate (Delivery) dated the date
hereof; with respect to the one (1) Engine having manufacturer's serial

                                      9-4
<PAGE>

number 688127 (which was previously delivered to, and accepted by Lessee under
the Pooling Agreement between Lessee and Alaska), the parties shall utilize the
data recorded in note 1 of Schedule 1 to the aforesaid Technical Acceptance
Certificate (Delivery); and in the case of all Engines, the data referred to in
Section D (Engine Records) of the Exhibit C hereto. In all events, each Engine
shall have at least five hundred (500) Hours and two hundred fifty (250) Cycles
remaining to its next scheduled shop visit. Subject to such minimum limitation
on Hours/Cycles as of the return date, any deviation from the aggregate
Hour/Cycle configuration for any Engine will be accepted by Lessor subject to
the return condition adjustment provided for in Section 9.8.


           9.7   Maintenance Program Conversion.
                 -------------------------------

                 (a)   As of the Delivery Date, the Aircraft is being maintained
under the Alaska maintenance program. In order to convert Hour/Cycle or calendar
time requirements applicable to the Airframe, landing gears and other time-
controlled components (exclusive of Engines) under Alaska's maintenance program
as in effect on the Delivery Date to Lessee's Maintenance Program which shall be
applicable as of the return of the Aircraft, the parties agree to utilize the
percentage ratios prescribed by the FAA's Advisory Circular No. 121. lA, dated
June 26, 1973 (as illustrated by Method A set forth in Appendix 1 thereto,
entitled "Procedures for Converting Calendar Overhaul (Months) To Hours Since
Overhaul For Prorations Purposes") as amended or updated as the date the
Aircraft is returned to Lessor. For the purposes of this Section 9.7, the
normalized block "D" check interval under the Lessee's Maintenance Program shall
be 24,000 Hours.

                 (b)   With respect to "hard time" components other than
Engines, landing gears and the APU, to the extent Lessee's Maintenance Program
differs from the Alaska maintenance program in terms of allowable
times/intervals to the next limiting inspection/overhaul, the return condition
requirements hereunder shall be the more restrictive of (i) the adjusted,
prorata percentage difference, if any, between the allowable time/intervals
under the Alaska maintenance program and Lessee's Maintenance Program and (ii)
the actual times remaining until the next limiting inspection/overhaul under the
Alaska maintenance program as such program was in effect on the Delivery Date.
The foregoing shall not apply to components which are maintained in an "on
condition basis under the Lessee's Maintenance Program. Such components shall be
returned to Lessor in an airworthy condition.


                                      9-5

           9.8   Return Condition Adjustment.
                 ----------------------------

                 (a)   Any provisions of this Section 9 to the contrary
notwithstanding, in the event there are any differences between the return
conditions of the Aircraft, including any Engine (subject to the minimum
Hour/Cycle limitations set forth in paragraphs (e) and (f) of Section 9.5 and
Section 9.6), the landing gears, and other time-controlled components installed
thereon or associated therewith, required by this Section 9 of the Lease and the
actual condition of the Aircraft on the return, such differences (including both
those in favor of Lessee and Lessor) shall be subject to financial adjustment
(the "Return Condition Adjustment") as provided by this Section 9.8. The
monetary value of any differences measured by Hours, Cycles, or calendar times
to, or since the prescribed overhauls and/or inspections mandated by the
Maintenance Program, or any applicable Federal Aviation Regulations, and any
Airworthiness Directives or other, emergency orders of the FAA, shall be
determined as of the date the Aircraft is returned to Lessor by taking the
average of the price quotations of three independent, FAA Repair Stations
located in the continental United States, for the conduct of the overhauls
and/or inspection services required to bring the Aircraft, Engines, landing
gears and other time-controlled components into compliance with the return
conditions required by this Section 9. For the purpose of obtaining such price
quotations, Lessee shall select the repair stations or overhaul agencies subject
to the approval of Lessor which approval shall not be unreasonably withheld. At
least five (5) Business Days prior to the return of the Aircraft, Lessee shall
furnish Lessor with a preliminary estimate of the Return Condition Adjustment
applicable to the Aircraft, if any. All amounts owed hereunder by either Lessee
or Lessor shall be settled on a net basis on the return of the Aircraft.

                 (b)   The provisions of Section 6.2 and paragraph (a) of this
Section 9.8 to the contrary notwithstanding, beginning on the one hundred
eightieth (180th) day, but no later than the one hundred twentieth (120th) day,
prior to the end of the Term, Lessee shall provide Lessor a written report
setting forth an estimate, based on contemporaneous and projected utilization
rates for the Airframe and each Engine, of the differences, if any, between the
return conditions of the Airframe and Engines, the landing gear and other time-
controlled components installed thereon or associated therewith as when accepted
by Lessee on the Delivery Date and as of the then-expected date of return at the
end of the Term. Should such estimate indicate that Lessor will be required to
make a Return Condition Adjustment in favor of Lessee as provided by paragraph
(a) of this Section 9.8, Lessee's obligation to make further payments of Basic
Rent shall be abated by the estimated amount of such Return Condition Adjustment
up to a maximum of two hundred thousand dollars ($200,000); provided, however,
that any amounts then due to Lessor as Supplemental Rent shall have been fully
paid by Lessee, and provided, further, that any abatement of Basic Rent pursuant
to this paragraph (b) of


                                      9-6
<PAGE>

Section 9.8 shall be subject to a final accounting and adjustment based on the
actual condition of the Aircraft on its return to Lessor at the end of the Term.
Any abatement of Basic Rent pursuant to this paragraph (b) of Section 9.8 shall
satisfy in full Lessor's obligation to make a Return Condition Adjustment in
favor of Lessee under this Lease.

           9.9   Engine Inspections. A borescope inspection shall be performed
                 ------------------
under the surveillance of Lessor at Lessee's expense at the time of the
Aircraft's return, and Lessee shall provide evidence satisfactory to Lessor that
no discrepancies exist beyond the applicable Pratt & Whitney shop repair limits
including no abnormal repetitive inspection limits.

           9.10  Inspection.
                 -----------

                 (a)   Lessor may, from time to time, wish to make the Aircraft
available for inspection to designated representatives or technical teams
evaluating the Aircraft for use after the Term. Lessor agrees to give Lessee not
less than five (5) Business Days' advance notice of such inspection and Lessee
agrees to cooperate with Lessor's requests in making the Aircraft and the
Manuals and Technical Records available to such authorized technical teams and
Lessor agrees that such requests will be reasonable and will be coordinated with
Lessee so as to minimize disturbance to its personnel. No such inspection shall
interfere with or delay Lessee's normal operations or the operations and use of
the Aircraft.

                 (b)   The Aircraft and the Manuals and Technical Records to be
returned therewith shall be made available to Lessor for ground inspection by
Lessor while the "C" check or its equivalent required by Section 9.5(a) is being
performed. During the "C" check required by Section 9.5(a), while Lessee has
removed the Aircraft from scheduled service and opened the areas of the Aircraft
as required by the applicable routine cards, Lessee shall allow Lessor to
accomplish its inspection in order to determine that the Aircraft (including the
Manuals and Technical Records) is in the condition required by the provisions of
this Section 9. Lessee at its sole cost and expense shall promptly correct any
discrepancies from the condition required by the provisions of this Section 9.

           9.11  Operational Ground Check. Promptly after completion of any
                 ------------------------
corrections required under Section 9.10, Lessee shall conduct an operational
ground check in accordance with the requirements of the Maintenance Program and
shall correct any discrepancies disclosed by such check.

           9.12  Operational Check Flight. Promptly after completion of all
                 ------------------------
corrections required under Sections 9.10 and 9.11 above, the Aircraft shall be
check

                                      9-7
<PAGE>

flown by Lessee at Lessee's expense, using qualified flight personnel for the
purpose of demonstrating to Lessor the satisfactory operation of the Aircraft
and its equipment and systems for normal passenger use. Such check flight shall
not exceed two (2) hours' duration and shall be conducted in accordance with the
specifications set forth in Exhibit E. Up to two (2) duly qualified Lessor
employees or representatives may participate in such flight as observers.
Lessee's flight crew shall be in command of the Aircraft. Upon completion of
such operational check flight, the representatives of Lessee and Lessor
participating in such flight shall agree in writing upon any discrepancies in
such Aircraft required to be corrected by Lessee in order to comply with
provisions of this Section 9 and Lessee shall promptly correct or cause to be
corrected at Lessee's expense any such discrepancies. If any of the
discrepancies referred to in Sections 9.11 and 9.12 or 9.13 continue to persist,
Lessor may (but shall not be obligated to) accept delivery of the Aircraft and
apply the procedure set forth in Section 9.14 for such discrepancies.

           9.13  Acceptance. Unless otherwise mutually agreed, the operational
                 ----------
check flight shall take place at the Return Location. Upon completion of the
operational check flight or after Lessee has corrected the discrepancies as
required to comply with this Section, the Aircraft shall be technically accepted
by Lessor's representatives at the Return Location.

           9.14  Deferred Return Condition Discrepancy Correction. If,
                 -------------------------------------------------
notwithstanding Lessee's best efforts to fully comply with the provisions of
Section 9 hereof, any return condition discrepancies are found during the ground
inspection, operational ground check and operational check flight set forth in
Sections 9.10, 9.11 and 9.12 above, which were not corrected by Lessee prior to
return of the Aircraft to Lessor, such discrepancies may be corrected by Lessor
or its designee after return of the Aircraft and Lessee shall reimburse Lessor
for all reasonable costs and expenses incurred by Lessor or its designee for
accomplishing such discrepancy corrections. Lessee shall, within 30 days of the
receipt of Lessor's invoice, pay Lessor for all such costs and expenses. Any
late payments shall be subject to interest at the Overdue Rate. Notwithstanding
the other provisions of this Section 9.14 to the contrary, Lessee shall fully
perform the "C" check required pursuant to Section 9.5(a) hereof prior to the
return of the Aircraft to Lessor.

           9.15  Flight Cost. All flights pursuant to Section 9.12 shall be made
                 -----------
at Lessee's expense and Lessee shall pay for any and all costs associated with
such flights including, but not limited to, costs for crew, fuel, oil, airport
fees, insurance, takeoff/landing fees, airway communication fees, and ground
handling fees, if any. With respect to any flight made pursuant to Section 9.12,
Lessee's obligations will be (i) to maintain the insurance required under this
Lease with respect to the Aircraft, proceeds of which shall be payable as
provided herein, and (ii) to indemnify Lessor pursuant to


                                      9-8
<PAGE>

Section 15 hereof. All other obligations and risks with respect to the Aircraft
under this Lease or otherwise shall be Lessor's from and after technical
acceptance by Lessor under Section 9.13, except as otherwise expressly provided
herein.

           9.16  Manuals and Technical Records. Lessee shall return to Lessor,
                 -----------------------------
at the time the Aircraft is returned to Lessor, all of the Manuals and Technical
Records and other data described in Exhibit C hereto, originally received from
Lessor, and subject to FAA retention time limits, updated and maintained by
Lessee through the date of return of the Aircraft. In addition, Lessee shall
also provide Lessor, at the time the Aircraft is returned to Lessor, all
records, documents, manuals, authorizations, drawings and data in English (or
with English translations thereof) which were developed or caused to be
developed by Lessee and required by the FAA, updated and maintained by Lessee
for the Aircraft and through the date of return of the Aircraft in an accurate
and correct condition. (All documentation, of any type, referred to in the
preceding two sentences or otherwise listed in Exhibit C hereto, is herein
individually and collectively referred to as the "Aircraft Documentation".) At
the time of return of the Aircraft Documentation for the Aircraft to Lessor and
provided the Aircraft Documentation is in the condition it is required to be in,
Lessee and Lessor shall execute an aircraft documentation return receipt.

           9.17  [Intentionally Left Blank)

           9.18  Lessee's Special Exterior Markings. At the time of the return
                 ----------------------------------
of the Aircraft, Lessee shall remove or paint over, at Lessor's election, all of
Lessee's logos and other exterior markings painted on the Aircraft so that such
logos and markings shall match the color of the adjacent areas and such work
shall be accomplished in a workmanlike manner. In the event that,
notwithstanding Lessee's obligation to do so, Lessee does not remove such
markings, Lessor shall have no obligation to remove such markings prior to the
sale, lease, or other disposition of the Aircraft by Lessor after its return;
however, if Lessor elects to remove such markings, Lessee shall within 30 days
of the receipt of Lessor's invoice pay Lessor's reasonable costs and expenses
for such removal. Any late payments shall be subject to interest at the Overdue
Rate.

           9.19  Ownership. Subject to the provisions of Section 8.5(d), any
                 ---------
documents, equipment and any other items returned to Lessor pursuant to this
Section 9 which are not already owned by Lessor shall thereupon and without
further act become the property of Lessor.

           9.20  Parking of Aircraft Upon Return. Upon the written request of
                 -------------------------------
Lessor given at least 15 Business Days prior to the end of the Term, Lessee, at
Lessor's expense and subject to the availability of manpower and facilities,
shall provide parking


                                      9-9

facilities for the Aircraft at the return location for a period not to exceed 90
days (the "Parking Period"). During the Parking Period, Lessee shall carry
insurance on the Aircraft as though the Aircraft were to remain in Lessee's
fleet in a non-flight status and Lessor agrees to reimburse Lessee for the
additional premium, if any, for such insurance coverage. At Lessor's request and
expense, Lessee shall ferry the Aircraft to a location within the continental
United States designated by the Lessor and in connection therewith obtain such
permits and insurances as may be required.

   SECTION 10. TITLE; REGISTRATION; LIENS.
               ---------------------------

     10.1 Title. Lessee acknowledges that full legal title to the Aircraft shall
          -----
remain vested in Lessor, notwithstanding the possession and use thereof by
Lessee, and Lessee shall do all acts and things Lessor may reasonably require to
evidence the interest of Lessor in the Aircraft or to protect such interest
against the claims of any other person. Lessee shall not attempt to hold itself
out as having any power to sell or dispose of the Aircraft or any Engine.

     10.2 Registration. Lessee acknowledges that, throughout the Term, the
          ------------
Aircraft shall be registered in the name of Lessor and Lessee shall not do, and
shall further use its best endeavors to ensure that no third party does, any act
or things which might prejudice or cancel such registration.

     10.3 Liens. Lessee shall not directly or indirectly create, incur, assume
          -----
or suffer to exist any Lien on or with respect to the Airframe or any Engine
other than Permitted Liens. Lessee shall promptly, at its own expense, take such
action as may be necessary to duly discharge any Lien other than a Permitted
Lien if the same shall arise at any time, which obligations of the Lessee shall
survive the termination of this Agreement.

     10.4 Notice of Ownership. As soon as practicable after the Delivery Date
          -------------------
but in any event within ten Business Days after the Delivery Date, Lessee shall
affix in a reasonably prominent position on the flight deck or cockpit, and on
each of the Engines, a reasonably legible notice reading as follows:

     "Investors Asset Holding Corp., as Trustee,
     Owner and Lessor

     Leased to AMERICAN TRANS AIR, INC.,
     Lessee"

   Once affixed as aforesaid, such notice shall not be defaced, covered or
removed during the Term, unless Lessor instructs Lessee to change such notice.
Lessee will not allow the name of any person other than Lessor to be placed on
the Airframe or any Engine as a designation that might be interpreted as a claim
of ownership or any interest therein, provided, however, that Lessee may operate
the Aircraft in its livery, including its name and logo.

   SECTION 11.  INSURANCE.
                ----------

   On or before the Delivery Date and throughout the Term, Lessee shall without
cost or expense to Lessor obtain, maintain and keep in full force and effect the
following insurances with respect to the Aircraft, carried with insurers of
recognized and good reputations in the aviation industry.

     11.1 All-Risk Insurance. "All-risk" hull, ground and flight insurance on
          ------------------
the Aircraft (with flight, taxiing and ingestion coverage) in an amount not less
than the Stipulated Loss Value. In addition, Lessor may request such greater
amounts of coverage as Lessor may determine necessary or desirable from time to
time (and for which Lessor shall reimburse Lessee for its cost of increased
premium, if any, for such greater amounts of insurance), provided that such
insurance is obtainable without limiting the insurance which Lessee carries to
cover its interest in the Aircraft. The insurances required hereby shall also
cover Engines or engines and Parts temporarily removed from the Airframe pending
installation of the same or similar Engines, engines or Parts on the Airframe in
an aggregate amount not less than their replacement cost.

     11.2 War Risk Insurance. War risk and allied perils insurance on the
          ------------------
Aircraft in an amount not less than the Stipulated Loss Value covering the
perils of:

          (a)  war, invasion, acts of foreign enemies, hostilities (whether war
be declared or not), civil war, rebellion, revolution, insurrection, martial
law, military or usurped power, or attempts at usurpation of power;

          (b)  strikes, riots, civil commotions or labor disturbances;

          (c)  any act of one or more persons, whether or not agents of a
sovereign power, for political or terrorist purposes and whether the loss or
damage therefrom is accidental or intentional;

          (d)  any malicious act or act of sabotage;

          (e)  confiscation, nationalization, seizure, restraint, detention,
appropriation, requisition of title or use by or under the order of any
government (whether civil, military or de facto) or public or local authority
other than the government or any public or local authority of the country of
registration; and

          (f)  hijacking or any unlawful seizure or wrongful seizure or wrongful
exercise of control of the Aircraft or crew in flight (including any attempt at

                                     11-1
<PAGE>

such seizure or control) made by any person or persons on board the Aircraft
acting without the consent of Lessee.

     11.3 Deductibles. For the insurances required by Sections 11.1 and 11.2
          -----------
hereof, Lessee may self-insure for events that are not a Total Loss in amounts
not more than $500,000 or such other amount that becomes the industry standard,
as set by the insurers, for insurance usually carried by corporations engaged in
the same or similar business, similarly situated with Lessee and owning and
operating similar aircraft or engines, and covering risks of the kind
customarily insured against by such corporations.

     11.4 Liability Insurance. Public liability insurance for a combined
          -------------------
single limit of not less than  $400,000,000 per occurrence or such greater
amounts as Lessee may carry from time to time on other Boeing 727-200 aircraft
in its fleet, which shall:

          (a)  include public liability insurance, passenger liability insurance
and property damage liability insurance; and

          (b)  provide that all the provisions thereof, except the limits of
liability, shall operate in the same manner as if there were a separate policy
covering each such insured.

   In the event that Lessee increases its public liability insurance coverage,
it shall do so with respect to the Aircraft contemporaneously with increasing
its insurance coverage on other aircraft which it owns or operates.

     11.5 Additional Requirements; Loss Payment. The insurance required under
          -------------------------------------
this Section 11 shall be provided on an agreed value basis, and the policies
shall:

          (a)  name Lessor and Beneficiary as additional insureds and as loss
payees for the account of all interests for up to the Stipulated Loss Value for
a Total Loss of the Aircraft and, provided that no Event of Default has occurred
and is continuing, name Lessee as loss payee for any additional insurance
carried by Lessee above the Stipulated Loss Value;

          (b)  provide that the insurance shall not be invalidated by any action
or inaction by Lessee and insure the interest of Lessor regardless of any breach
or violation by Lessee or any other named insured of any warranty, declaration
or condition contained in such policies;

          (c)  provide that the insurers shall waive any right of subrogation to
any right of Lessor or against Lessor:

                                     11-2

<PAGE>
          (d)  provide that in the event of separate insurance being arranged to
cover the all-risk hull insurance and the war risk and allied perils insurance,
the underwriters subscribing to such insurance agree to a 50/50 claim funding
arrangement in the event of any dispute as to which insurance is applicable;

          (e)  be primary and without right of contribution from other insurance
which may be available to Lessor;

          (f)  extend to, and the underwriters thereof have agreed to insure,
the indemnification provided in Section 15.1 hereof to the extent that such
insurance is available and carried by Lessee and subject to the exclusions and
limitations of Lessee's policies;

          (g)  be of the type usually carried by corporations engaged in the
same or a similar business, similarly situated with Lessee and owning and
operating similar aircraft and engines in commercial air transportation
operations, and covering risks of the kind customarily insured against by such
corporations;

          (h)  provide that Lessor shall have not liability for premiums,
commissions, calls or assessments with respect to such policies; and

          (i)  provide in the case of the insurance required by Sections 11.1
and 11.2 hereof that so long as the insurers shall not have received written
notice that a Default or an Event of Default has occurred and is continuing, any
proceeds of less than $1,000,000 shall be payable to Lessee, and any proceeds in
excess of $1,000,000, and any and all proceeds in respect of a Total Loss, or if
the insurers shall have received written notice that a Default or an Event of
Default has occurred and is continuing, any single loss regardless of the
amount, shall be payable to Lessor.

     11.6 No Set-off. Each insurance policy to be maintained under this Section
          ----------
11 shall contain a waiver of any right of the insurers to any set-off or
counterclaim or any other deduction against Lessee or Lessor.

     11.7 Notice of Material Alteration or Cancellation. Each insurance policy
          ---------------------------------------------
to be maintained under this Section 11 shall provide that no cancellation or
lapse of coverage for nonpayment of premium or otherwise, and no substantial
change of coverage which adversely affects Lessor shall be effective as to
Lessor until not less than 30 days (seven (7) days in the case of war risk
policies, subject to exceptions uniformly applied in war risk policies then
available in commercially reasonable time) after sending written notice to
Lessor from the insurers of such cancellation, lapse or change.

                                     11-3
<PAGE>

     11.8  Application of Hull Insurance Proceeds. As between Lessor and
           --------------------------------------
Lessee, any payments received under policies of insurance required to be
maintained by Lessee pursuant to Sections 11.1 or 11.2, shall be applied as
follows:

           (a)  if such payments are received by Lessor with respect to loss or
damage (including a Total Loss with respect to an Engine) not constituting a
Total Loss with respect to the Airframe such payments shall be paid over to
Lessee upon Lessee's performance of its repair or replacement obligations under
this Lease pursuant to Section 12.3 hereof; and

           (b)  if such payments are received with respect to a Total Loss with
respect to the Airframe, so much of such payments as shall not exceed the amount
required to be paid by Lessee pursuant to Section 12.1 hereof shall be applied
in reduction of Lessee's obligation to pay such amount if not already paid by
Lessee, and to reimburse Lessee if it shall have paid all or part of such
amount, and the balance, if any, of such payments shall be paid over to or
retained by Lessee.

     11.9  Insurance for Own Account. Nothing in this Section 11 shall prohibit
           -------------------------
Lessor or Lessee from obtaining insurance for its own account and any proceeds
payable thereunder shall be payable as provided in the insurance policy relating
thereto, provided that no such insurance may be obtained which would limit or
otherwise adversely affect the coverage or payment of any insurance required to
be obtained or maintained pursuant to this Section 11.

     11.10 Reports. Lessee shall furnish to Lessor and Beneficiary not later
           -------
than the Delivery Date a report signed by a firm of independent insurance
brokers satisfactory to Lessor stating the opinion of such firm that the
insurances then carried and maintained on the Aircraft comply with the terms
hereof. Lessee will during the Term furnish to Lessor evidence of renewal of the
insurance policies required pursuant to this Section 11 prior to the
cancellation, lapse or expiration of such insurance policies. Such evidence of
renewal shall consist of a certificate signed by a firm of independent aircraft
insurance brokers, certifying that the insurances required by this Section 11,
and the additional requirements related thereto are in full force and effect.
Lessee will cause such firm to advise Lessor in writing promptly of any default
in the payment of any premium and of any other act or omission on the part of
Lessee in which they have knowledge and which would in such firm's opinion
invalidate or render unenforceable, in whole or in any material part, any
insurance on the Aircraft. Lessee will also cause such firm to advise Lessor in
writing at least 30 days (seven (7) days in the case of war risk policies) prior
to the termination or cancellation of, or material adverse change in such
insurance carried and maintained on the Aircraft pursuant to this Section 11.

     11.11  Changes in Industry Practice. If there shall be fundamental change
            ----------------------------
in generally accepted industry-wide practice with respect to the insurance of
aircraft (whether relating to all or any of the types of insurance required to
be effected pursuant to the terms of this Section ii) and as a consequence
thereof Lessor shall be of the reasonable opinion that the insurance required
pursuant to the provisions of this Section 11 shall be insufficient to protect
the interests of Lessor, the insurance requirements set forth in this Section 11
shall be varied as may be mutually agreed so as to include such additional or
varied requirements to be effected pursuant to the terms of this Section II, and
as so varied, shall provide the same protection to Lessor as it would have done
had such change in generally accepted industry-wide practice not occurred. If
any such change in generally accepted industry-wide practice would enable
Lessee, but for the requirements in this Section 11, to reduce its expenditures
in relation to all or any of the types of insurance required to be effected
pursuant to the terms of this Section 11 without, in the reasonable opinion of
Lessor, prejudicing the interest of Lessor, the insurance requirements in this
Section 11 shall be amended to take account of such change in generally accepted
industry-wide practice to the extent required to enable Lessee to reduce such
expenditures; provided, however, that in no event shall Lessee reduce any of the
insurance required under this Section 11 without the written consent of the
Lessor.

     11.12  Continuing Insurance. Subject to the provisions of this Section 11,
            --------------------
Lessee's insurance coverage shall cover all liabilities which arise during the
Term, regardless of the date on which any claim is made with respect to such
occurrence. Lessee shall in any event be responsible for any and all liabilities
to which Lessor may be exposed as a result of Lessee's Lease, use, possession,
or operation of the Aircraft.

   SECTION 12. LOSS. DAMAGE OR REQUISITION.
               ----------------------------

     12.1 Total Loss of Airframe.
          -----------------------

          Upon the occurrence of a Total Loss with respect to the Airframe
during the Term, Lessee shall give Lessor immediate written notice of such Total
Loss. Lessee shall pay or cause to be paid to Lessor in immediately available
funds within 30 days following the Total Loss, an amount equal to (A) the Basic
Rent, if any, due and payable on or before such payment date, plus (B) all
unpaid Supplemental Rent due on or before such payment date, (including the
Stipulated Loss Value for the Aircraft) plus (C) an amount equal to the daily
equivalent of Basic Rent for each day during the period commencing the day after
the last Rent Payment Date up to the date the payment required hereby is
actually made.

   In the event of a payment in full of the Stipulated Loss Value for the
Aircraft and other Rent payable as provided above, (x) this Lease and the
obligations of Lessee to pay Basic Rent and Supplemental Rent (except for
Supplemental Rent obligations surviving pursuant to Sections 15 and 16 hereof or
which have otherwise accrued but not been paid as of the date of such payment)
shall terminate; (y) any remaining insurance proceeds held by Lessor (other than
proceeds of policies maintained by Lessor for its own account) shall be promptly
paid over to Lessee; and (z) Lessor shall convey to Lessee all of Lessor's
right, tide and interest, "as-is, where-is," without recourse or warranty,
express or implied, except to warrant that it is free and clear of liens placed
thereon by Lessor in and to the Airframe and Engines.

     12.2 Engine Loss. Upon the occurrence during the Term of a Total Loss with
          -----------
respect to an Engine whether or not installed on the Airframe and not involving
a Total Loss with respect to the Airframe, Lessee shall give Lessor written
notice thereof within ten (10) Business Days of such loss and shall within 90
days of the occurrence of such Total Loss and on at least five (5) days' prior
written notice to Lessor substitute a Replacement Engine for such Engine;
provided, however, under all circumstances a Replacement Engine shall be
substituted on or before the expiration of the Term. In such event, immediately
upon the effectiveness of such substitution on the date set forth in such notice
and without further act,

          (1)  tide to the Replacement Engine shall thereupon vest in Lessor
(subject only to Permitted Liens),

          (2)  tide to the replaced engine shall thereupon vest in Lessee in
"as-is, where-is" condition, free and clear of all rights of Lessor and shall no
longer be deemed an Engine hereunder, and

                                     12-1
<PAGE>

          (3)  such Replacement Engine shall become subject to this Lease and be
deemed part of the Aircraft for all purposes hereof to the same extent as the
Engine originally installed on or attached to the Airframe.

   Upon such substitution, Lessee shall execute and deliver to Lessor such bills
of sale, opinions of counsel and other documents and instruments as Lessor shall
reasonably request to evidence the interest of Lessor and conveyance to Lessor
of good and marketable tide to such Replacement Engine. Upon such substitution,
(x) Lessor shall execute and deliver to Lessee such bills of sale and other
documents and instruments, prepared at Lessee's expense as Lessee shall
reasonably request to evidence such transfer and vesting of tide in and to the
replaced Engine in Lessee, free and clear of all rights of Lessor and (y) Lessee
shall receive all insurance proceeds and proceeds in respect of any Total Loss
causing such replacement to the extent not previously applied to the purchase
price of the Replacement Engine as provided in Section 12.3 hereof. No Total
Loss with respect to an Engine under the circumstances contemplated by this
Section 12.2 shall result in any reduction of Lessee's obligations to pay Rent
hereunder.

     12.3 Repairable Damage Use of Insurance Proceeds. In the event of
          -------------------------------------------
repairable damage to the Aircraft or any of the Engines, or any Engine loss
(when no Total Loss of the Aircraft has occurred), Lessor shall forthwith pay
any insurance proceeds received by it to Lessee upon Lessee's furnishing (i)
evidence to Lessor that such damage has been made good or repaired such that the
condition of the Aircraft shall be at least equivalent to its condition
immediately prior to the event of damage or, (ii) in the case of an Engine loss,
evidence that Lessee has purchased or otherwise acquired and installed a
Replacement Engine.

     12.4 Payment from Governmental Authorities for Requisition of Tide or Use.
          --------------------------------------------------------------------
In the event of a requisition for use by any government, so long as it does not
constitute a Total Loss of the Airframe, Lessee shall promptly notify Lessor of
such requisition and all Lessee's obligations under this Lease shall continue to
the same extent as if such requisition had not occurred except to the extent
that any failure or delay in the performance or observance of each obligation by
Lessee shall have been prevented or delayed by such requisition; provided,
however, that Lessee's obligations for the payment of money and its obligations
under Section 11 hereof shall in no way be affected, reduced or delayed by such
requisition. Any payments received by Lessor or Lessee from such government with
respect to such requisition shall be paid over to or retained by, Lessee. In the
event of the requisition for use by a government of any Engine (but not the
Airframe), Lessee will replace such Engine hereunder by complying with the terms
of Section 12.2 hereof to the same extent as if a Total Loss had occurred with
respect to such Engine. Any payments received by Lessor or Lessee from such
government with respect to such requisition shall be paid over to, or retained
by, Lessor until Lessee's

                                     12-2
<PAGE>

replacement of such Engine pursuant to Section 12.2 hereof, at which point they
shall be paid over to Lessee.

     12.5 Application of Payments During Existence of Event of Default. Any
          ------------------------------------------------------------
amount referred to in Sections 11 or 12 hereof which is payable to Lessee shall
not be paid to Lessee, or, if it has been previously paid directly to Lessee,
shall not be retained by Lessee, if at the time of such payment an Event of
Default shall have occurred and be continuing, but shall be paid to and held by
Lessor as security for the obligations of Lessee under this Lease.

     12.6 Prohibition of Use by the Government. The provisions of Section 6.2
          ------------------------------------
and this Section 12 to the contrary notwithstanding, upon the event of a Total
Loss resulting from a Prohibition of Use, either party may, upon the giving of
sixty (60) days' prior written notice to the other party (the "Early Termination
Notice"), terminate this Lease and the Aircraft shall thereupon be returned to
Lessor in accordance with the provisions of Section 9 hereof subject to the
terms, conditions and limitations of the rule, regulation, order or other action
of the FAA or other governmental body having jurisdiction, causing the
Prohibition of Use, including without limiting the generality hereof, any
suspension or cancellation by the FAA of the airworthiness certificate covering
the Aircraft, and upon such return Lessee shall pay to Lessor a special
termination payment equal to the balance of all Rent due under the Lease to the
end of the Term.

                                     12-3
<PAGE>

   SECTION 13. EVENT OF DEFAULT.
               -----------------

   Each of the following events shall be an Event of Default:

     13.1  Failure to Make Payments. If Lessee shall fail to make any payment of
           ------------------------
Rent when due which failure shall not have been cured within five (5) Business
Days;

     13.2  Failure to Obtain or Maintain Insurance. If Lessee fails to obtain or

8.2(a) hereof;

          ------------------------------------
or maintain any perform any of its other obligations or agreements under any
Operative Document to which Lessee is a party and such failure shall not have
been remedied within a period of 20 days after the earlier of delivery of
written notice specifying the same from Lessor or the date upon which Lessee
knew or should have known such event had occurred;

     13.4 Representations and Warranties Untrue. If any representation or
          -------------------------------------
warranty made by Lessee in any Lease Document or in any document or certificate
furnished to Lessor in connection therewith shall prove to be untrue in any
material respect;

     13.5 Insolvency or Bankruptcy.
          ------------------------

          (a)  If Lessee shall consent to the appointment of or taking
possession by a receiver, assignee, custodian, sequestrator, trustee or
liquidator (or other similar official) of itself or of a substantial part of its
property, or Lessee shall fail to pay its debts generally as they come due
(unless such debts are the subject of a bona fide dispute), or shall make a
general assignment for the benefit of its creditors, or Lessee shall commence a
voluntary case or other proceeding seeking liquidation, reorganization or other
relief with respect to itself or its debts under the Federal bankruptcy laws, as
now or hereafter constituted or any other applicable Federal or state
bankruptcy, insolvency or other similar laws or shall consent to the entry of an
order for relief in an involuntary case under any such law or Lessee shall file
an answer admitting the material allegations of a petition filed against Lessee
in any such proceedings or otherwise seek relief under the provisions of any now
existing or future Federal or state bankruptcy, insolvency or other similar laws
providing for the reorganization or winding-up of corporations, or providing for
an agreement, composition, extension or adjustment with its creditors.

<PAGE>

                     (b)     If an order, judgment or decree shall be entered in
any proceedings by any court of competent jurisdiction appointing, without the
consent of Lessee, a receiver, trustee or liquidator of Lessee, or of any
substantial part of its property, or any substantial part of the property of
Lessee shall be sequestered, and any such order, judgment or decree or
appointment or sequestration shall remain in force, unstayed or unvacated for a
period of 60 days after the date of entry thereof;

                     (c)     If a petition against Lessee in a proceeding or
case under the bankruptcy laws or other insolvency laws (as now or hereafter in
effect) shall be filed and shall not be withdrawn or dismissed within 60 days

        SECTION 14. REMEDIES.
                    --------

        Upon the occurrence of any Event of Default and at any time thereafter
so long as the same shall be continuing, Lessor may, at its option, declare this
Lease to be in default; and at any time thereafter, Lessor may do, and Lessee
shall comply with, one or more of the following with respect to all or any part
of the Airframe and the Engines, as Lessor in its sole discretion shall elect:

                     (a)     Cause Lessee, upon the written demand of Lessor and
at Lessee's expense, to, and Lessee shall, promptly return the Aircraft to
Lessor in accordance with all of the provisions of Section 9 hereof as if such
Airframe or such Engines were being returned at the end of the Term; or Lessor,
at its option, may enter upon the premises where the Airframe or any or all
Engines are located or believed to be located and take immediate possession of
and remove such Airframe or Engines without the necessity for first instituting
proceedings, or by summary proceedings or otherwise, and Lessee shall comply
therewith, all without liability to Lessor for or by reason of such entry or
taking possession, whether for the restoration or damage to property caused by
such taking or otherwise;

                     (b)     Sell or otherwise dispose of the Aircraft, at
public or private sale and with or without notice to Lessee or advertisement, as
Lessor may determine or hold, use, operate, lease to others all or any part of
the Airframe or any Engine as Lessor, in its sole discretion, may determine, in
any such case free and clear of any rights of Lessee and without any duty to
account to Lessee with respect to such action or for any proceeds with respect
thereto except to the extent required by paragraph (d) below in the event Lessor
elects to exercise its rights under said paragraph in lieu of its rights under
paragraph (c) below;

                     (c)     Whether or not Lessor shall have exercised, or
shall thereafter at any time exercise, any of its rights under paragraph (a) or
paragraph (b) of this Section 14, Lessor, by five (5) days written notice to
Lessee specifying a payment date, may demand that Lessee pay to Lessor, and
Lessee shall pay to Lessor, on the payment date specified in such notice, as
liquidated damages for loss of bargain and not as a penalty (in lieu of the
Basic Rent due for the period commencing after the date specified for payment in
such notice), any unpaid Rent for the Aircraft (prorated in the case of Basic
Rent on a daily basis) to and including the payment date specified in such
notice, plus an amount, equal to the greater of (i) one hundred twenty five
        ----
percent (125%) of the aggregate Basic Rent the period commencing on the payment
date specified by the aforesaid notice to the end of Term or (ii) six (6)
months' Basic Rent ($381,000).

                     (d)     Rescind this Lease as to the Aircraft or exercise
any other right or remedy which may be available under Applicable Law or proceed
by appropriate court action to enforce the terms hereof or to recover damages
for the breach hereof. In addition, Lessee shall be liable for any and all
Supplemental Rent due hereunder before or after any termination hereof,
including all costs and expenses (including reasonable attorneys' fees and
disbursements) incurred by reason of the occurrence of any Event of Default or
the exercise of Lessor's remedies with respect thereto including all costs and
expenses incurred in connection with the return of the Airframe or any Engine in
accordance with the terms of Section 9 hereof or any appraisal of the Aircraft.
No remedy referred to in this Section 14 is intended to be exclusive, but each
shall be cumulative and in addition to any other remedy referred to above or
otherwise available to Lessor at law or in equity; and the exercise or beginning
of exercise by Lessor of any one or more of such remedies shall not preclude the
simultaneous or later exercise by Lessor of any or all such other remedies. No
express or implied waiver by Lessor of any Event of Default hereunder shall in
any way be, or be construed to be, a waiver of any future or subsequent Event of
Default.

        SECTION 15. GENERAL INDEMNITIES.
                    -------------------

                15.1 General Indemnification and Waiver of Certain Claims.
                     ----------------------------------------------------

                     (a)     Claims Defined. For the purposes of this Lease,
                             --------------
"Claims" shall mean any and all liabilities (including strict or absolute costs,
actions or suits and all legal proceedings whether civil or criminal, fines and
other sanctions), which may be imposed on, incurred by, suffered by, or asserted
against Lessor, and if Lessor is a trustee under any trust, a beneficiary,
trustee, or lender or any officer, director, employee, shareholder, partner or
affiliate of any of the foregoing (individually, an "Indemnified Person" for
purposes of this Section 15.1) and, except as otherwise expressly provided in
this Section 15.1, shall include all reasonable costs, disbursements and
expenses (including legal fees and expenses) of an Indemnified Person in
connection therewith or related thereto.

                     (b)     Claims Indemnified. Subject to the exclusions
                             ------------------
stated in subsection (c) below, Lessee agrees to indemnify, defend and hold
harmless each Indemnified Person against Claims resulting from, arising out of,
or related to:

                             (i)   the operation, possession, use, non-use,
maintenance, storage, overhaul, testing or disposition of the Aircraft, Airframe
or any Engine, or any engine used in connection with the Airframe, or any part
thereof by Lessee or any other Person whatsoever, whether or not such operation,
possession, use, non-use, maintenance, storage, overhaul or testing is in
compliance with the terms of the Lease, including, without limitation, Claims
for death, personal injury or property damage or other loss or harm to any
Person whatsoever, including, without limitation, any passengers, shippers or
other persons wherever located, and Claims relating to any laws, rules or
regulations, including, without limitation, environmental control, noise and
pollution laws, rules or regulations;

                             (ii)  the manufacture, design, sale, purchase,
acceptance, rejection, delivery, condition, repair, modification, servicing,
rebuilding, airworthiness, performance, nondelivery, sublease, merchantability,
fitness for use, substitution or replacement of the Airframe, an Engine or part
under the Lease, or other transfer of use or possession of the Aircraft,
Airframe, Engine or Part, and registration of the Aircraft, Airframe or any
Engine, including, without limitation, latent and other defects, whether or not
discoverable, and patent, trademark or copyright infringement; and

                             (iii) any breach of or failure to perform or
observe, or any other non-compliance with, any covenant or agreement to be
performed, or other obligation of Lessee under any Lease Document.

                                     15-1
<PAGE>

                     (c)     Claims Excluded. The following are excluded from
                             ---------------
Lessee's agreement to indemnify under this Section 15.1:

                             (i)   Claims attributable to acts or events
occurring after the return of the Aircraft to Lessor whether at the expiration
of the Basic Term or otherwise; and

                             (ii)  Claims which are Taxes for which Lessee is
required to indemnify Lessor under Section 16 hereof.

                             (iii) Claims caused by, or arising out of the gross
negligence or willful misconduct of any Indemnified Person.

                     (d)     Claims Procedure. An Indemnified Person shall
                             ----------------
promptly notify Lessee of any Claim as to which indemnification is sought.
Lessee shall have the right to investigate and the right to defend, and with the
prior written consent of such Indemnified Party, such consent not to be
unreasonably withheld, compromise any Claim for which indemnification is sought
under this Section 15.1, and the Indemnified Person shall cooperate with all
reasonable requests of Lessee in connection therewith; provided that at such
time no Event of Default shall have occurred and be continuing. In discharging
its obligations under this Section 15.1 Lessee agrees to utilize counsel
reasonably acceptable to such Indemnified Person. An Indemnified Person may
participate at its own expense in any judicial proceeding controlled by Lessee
pursuant to the preceding provisions, and such participation shall not
constitute a waiver of the indemnification provided in this Section 15.1.
Nothing contained in this Section 15.1(d) shall be deemed to require an
Indemnified Person to contest any Claim or to assume responsibility for or
control of any judicial proceeding with respect thereto.

                     (e)     Subrogation. To the extent that a Claim indemnified
                             -----------
by Lessee under this Section 15 is in fact paid in full by Lessee and/or an
insurer under a policy of insurance maintained by Lessee pursuant to Section 11
of the Agreement, Lessee and/or such insurer as the case shall be subrogated to
the rights and remedies of the Indemnified Person on whose behalf such Claim was
paid with respect to the transaction or event giving rise to such Claim. Should
an Indemnified Person receive any refund, in whole or in part, with respect to
any Claim paid by Lessee hereunder, it shall promptly pay the amount refunded
(but not an amount in excess of the amount Lessee has paid in respect of such
Claim) over to Lessee.

                     (f)     Indemnification on After-Tax Basis. In the event
                             ----------------------------------
Lessee is required to indemnify any Indemnified Person under this Section 15.1
Lessee shall pay to such Indemnified Person an amount which, after deduction of
all Taxes actually


                                     15-2
<PAGE>

required to be paid by such Indemnified Person in respect of the receipt of such
amount under the Applicable Laws of any government or taxing jurisdiction (after
giving credit for any saving in respect of any such Taxes by reason of
allocations, allowances, credits, deductions or other tax benefits related to
the payment of the Claim indemnified against and the payment of related Taxes),
shall be equal to the amount of the indemnification required.

                     (g)     Waiver of Certain Claims. Lessee hereby waives and
                             ------------------------
releases any Claim now or hereafter existing against any Indemnified Person
arising out of death or personal injury to personnel of the Lessee, loss or
damage to property of Lessee, or the loss of use of any property of Lessee,
which may result from or arise out of the condition, use or operation of the
Aircraft during the term, including without limitation any latent or patent
defect whether or not discoverable.

                     (h)     Conflicting Provisions. The general indemnification
                             ----------------------
provisions of this Section 15.1 are not intended to waive or supersede any
specific provisions of this Lease to the extent such provisions apply to any
Claim.

                15.2 Continuing Indemnification.  The agreements and indemnities
                     --------------------------
contained in this Section 15 shall survive the end of the Term.

SECTION 16. TAX INDEMNITY.
            --------------

                16.1 Taxes and Other Charges.
                     -----------------------

                     (a)     Lessee shall pay, indemnify and hold Lessor
harmless from all Taxes which relate to the leasing of the Aircraft pursuant
hereto which may be, by any federal, state or local government in the United
States of America, foreign government, territory or possession of the United
States of America, or international taxing authority, or any subdivision or
taxing authority thereof (any such government, subdivision or authority, a
"Taxing Authority"), levied or assessed against, or imposed, prior to or during
the Term, on Lessor, the Aircraft or any part thereof upon or with respect to or
as a result of (i) the interest of Lessee or Lessor in the Aircraft, (ii) any
Rent, (iii) this Lease or the interest of Lessee or Lessor hereunder, (iv) the
manufacture, purchase, delivery, leasing, operation, return, possession, use,
occupancy, installation, construction, maintenance, repair, renewal or
modification of the Aircraft, the Airframe, the Engines, the Parts or any part
of any of the foregoing, (v) receipts from the Aircraft, or (vi) the earnings
arising from the possession, use or occupancy thereof. Without limitation of the
foregoing, Lessee shall also pay and discharge, as and when due and payable
without penalty, all Taxes which may be levied or assessed against or payable by
Lessee or Lessor on account of the ownership, leasing or use of the Aircraft,
and all Taxes or portions thereof imposed or levied upon or assessed against
Lessor in substitution for or in place of any other Tax required to be paid or
indemnified by Lessee pursuant to this Section 16.1(a). Notwithstanding the
foregoing provisions of this Section 16.1(a). Lessee shall not be required to
pay:

                             (A)   Taxes imposed on Lessor by any Taxing
Authority in which Lessor's principal place of business is located or in which
Lessor is subject to such Tax (or required to file Tax returns) in relation to
activities other than the acquisition, ownership, financing, installation,
construction, leasing or use of the Aircraft;

                             (B)   (i)   Taxes imposed by the United States of
America, or any Taxing Authority thereof, upon, with respect to, based on or
measured by the gross or net income, receipts or gain of Lessor, or taxes in
                                     ----------------
lieu thereof (including, without limitation, taxes collected by withholding,
minimum or alternative minimum taxes, excess profit taxes and taxes on or
measured by any item of tax preference) (such Taxes, whether imposed by the
United States of America or any other Taxing Authority, "Income Taxes");

                                   (ii)  Income Taxes imposed by any state or
local government in the United States, or any Taxing Authority thereof;


                                     16-1
<PAGE>

                                   (iii) Income Taxes imposed by any foreign
government, international authority, or territory or possession of the United
States, or any Taxing Authority thereof, except to the extent such Income Taxes
are imposed on Lessor with respect to Lessee's operation of the Aircraft within
the jurisdiction of such Taxing Authority, provided, however, that the amount of
Income Taxes as to which indemnity is available under this exception shall be no
greater than an amount which bears the same ratio to Lessor's total Income Taxes
imposed by such Taxing Authority as Lessor's taxable income from Lessee subject
to such Income Taxes bears to Lessor's total taxable income subject to such
Income Taxes, and provided further, however, that no indemnity is available
under this exception for Income Taxes paid or payable by or on behalf of Lessor
to the jurisdiction of Lessor's residence, citizenship, incorporation or
organization.

                             (C)   Taxes imposed as a result of (i) a voluntary
sale, transfer of tide, mortgaging, pledging, financing, voluntary transfer or
other voluntary disposition of the Aircraft, any part thereof or interest
therein, any interest in the rent to be paid hereunder or part thereof or any
interest in this Agreement or part thereof, unless such sale, transfer,
mortgage, pledge or disposition occurs by reason of the exercise of Lessor's
remedies under Section 14 hereof, or (ii) any involuntary transfer or
disposition of any of the foregoing interests in connection with any bankruptcy,
foreclosure, assignment for the benefit of creditors, or similar proceeding with
respect to Lessor unless such transfer or disposition occurs by reason of the
exercise by Lessor of its remedies under Section 14 hereof;

                             (D)   Taxes on, based on or measured by any fees or
compensation received by Lessor (other than Rent) for services rendered in
connection with the transactions contemplated hereby; or

                             (E)   Taxes relating to the Aircraft or any part
thereof, or interest therein, or to any of the actions set out in (C) above of
this Section 16.1(a) for or during any taxable period or portion thereof prior
to the earlier of (a) the Delivery Date or (b) the commencement of the Term or
after the later of (x) the expiration of the Term or (y) the redelivery of the
Aircraft in accordance with the Lease, except to the extent that any such Taxes
are imposed in connection with remedies exercised by Lessor under Section 14
hereof.

                     (b)     Lessee shall furnish to Lessor, upon Lessor's
written request, proof of the payment of any such Tax which is payable by Lessee
pursuant to Section 16.1(a).

                     (c)     Whenever the term "Lessor" is used in Section 16.1
and Sections 16.3 through 16.5 hereof, such term shall include Lessor, its
successors,


                                     16-2
<PAGE>

transferees, assigns and partners therein, and if any Lessor is a trust, the
beneficiary and the owner of, and any lender to, such trust and the partners of
each such beneficiary and owner.

                16.2 Certain Covenants.
                     -----------------

                     (a)     Lessee agrees that neither it nor any corporation
controlled by it, in control of it, or under common control with it, directly or
indirectly, shall at any time take any action or file any returns or other
documents inconsistent with the foregoing and that each such corporation shall
file such returns, take such action and execute such documents as may be
reasonably necessary to facilitate accomplishment of the intent hereof. Lessee
agrees to keep and make available for inspection and copying by Lessor such
records regularly maintained by Lessee other than tax returns as will enable
Lessor to prepare its tax returns or to contest any proposed disallowance or
adjustment of any deduction arising from the Aircraft or this Lease.

                     (b)     Lessee covenants that neither Lessee nor any
Affiliate will have claimed or will claim any depreciation deductions with
respect to the Aircraft.

                     (c)     The undertakings made in this Section 16.2 are
expressly made for the benefit of, and shall be enforceable by, Lessor. Whenever
the term "Lessor" is used in this Section 16.2, such term shall include Lessor,
its successors, transferees, assigns and partners therein, and if any Lessor is
a trust, the beneficiary and the owner of such trust, any lender to such trust,
and the partners of each beneficiary and owner, provided that the rights of any
transferee shall not exceed the rights of Lessor which Lessor would have
retained had no transfer occurred.

                16.3 Tax Savings.
                     -----------

                     If with respect to any amount paid or indemnified by Lessee
under Section 15 or this Section 16, Lessor shall realize any savings in respect
of any such amount by reason of deductions, credits, allocations, allowances or
other tax benefits (collectively, "Tax Benefits") therefor under the laws of any
Taxing Authority, Lessor shall promptly notify Lessee that it has realized such
Tax Benefit and shall pay to Lessee an amount equal to (i) the net reduction in
Taxes realized by Lessor as a result of such Tax Benefit under such laws and
(ii) the amount of any further net reduction in Taxes realized under such laws
as a result of payments pursuant to clause (i) of this sentence, in both cases
taking into account any tax detriment to Lessor attributable to such Tax Benefit
or payment and excluding any such net reduction otherwise taken into account in
calculating the amount of any payment by Lessee to Lessor as described in
Section 14 hereof; provided that such amount shall not be payable (x) before
such time as Lessee


                                     16-3
<PAGE>

shall have made all payments or indemnities then due to or on behalf of Lessor
under this Lease, (y) during any time that Lessor may be exercising its remedies
under Section 14 hereof or (z) to the extent it exceeds the amount of all
payments made by Lessee with respect to such Taxes. If any Tax Benefit is taken
into account under this Section 16.3 and it is subsequently determined that
Lessor was not entitled thereto, the disallowance thereof shall be treated as a
Tax that is indemnifiable under this Section 16.

                16.4 Payments.
                     --------

                     If a claim is made against Lessor for any Taxes, Lessor
shall promptly notify Lessee and in no event later than such time as would
permit Lessee timely to contest the imposition of such Taxes pursuant to Section
16.5 below; provided that Lessor shall not be required to notify Lessee prior to
the time that Lessor itself receives notice of a claim for Taxes. The failure
promptly to notify Lessee in accordance with the preceding sentence shall not
diminish Lessee's obligation hereunder unless such failure materially and
adversely affects Lessee's ability to require Lessor to contest the Tax. Any
amount payable as an indemnity to Lessor pursuant to this Section 16.4 is to be
paid to Lessor directly, in immediately available funds, within thirty (30) days
after receipt of a written demand therefor from Lessor, except that the payment
of such indemnity shall not be payable prior to the later of (a) the due date
for the payment of the indemnified Taxes and (1)) to the extent that such Taxes
are being contested in good faith pursuant to Section 16.5, the due date for the
payment of any Taxes that are the subject of such contest; provided, that in the
event that Lessor receives notice that Taxes related to such amount demanded are
due and payable within a period of 30 days or less following receipt of such
notice by Lessor and Lessor promptly makes a written demand on Lessee, then such
amount demanded shall be payable in no event after the later of (x) five (5)
business days after receipt of such demand by Lessee or (y) three (3) business
days prior to the due date of the related Taxes.

                     In the event Lessor makes a tax payment with respect to any
such Taxes (other than with funds advanced to Lessor on an interest-free basis
by Lessee pursuant to this Section 16), Lessee shall pay to Lessor interest on
the amount of such payment at the Prime Rate from the date of Lessor's payment
to the relevant taxing authority to the date of such payment by Lessee to
Lessor. In the event an amount is payable to Lessee under this Section 16,
Lessor shall pay interest on such amount at the Prime Rate from the date of
receipt by Lessor of any amount giving rise to such obligation to pay Lessee
until the date of payment to Lessee.


                                     16-4
<PAGE>

     16.5 Contests.
          ---------

          If requested by Lessee in writing, Lessor shall upon receipt of
indemnity reasonably satisfactory to it and at the sole expense of Lessee
(including, without limitation, all out-of-pocket costs and expenses, legal and
accounting and investigatory fees and disbursements, additions to tax because of
underpayments of estimated Taxes, penalties, and interest (such amounts, without
limitation, the "Expenses")) in good faith contest (and not settle without
Lessee's written consent) or shall permit Lessee, if desired by Lessee, to
contest in the name of Lessee and/or Lessor the validity, applicability or
amount of Taxes indemnified hereunder (including, without limitation, 15.1 (f))
by (i) delaying payment thereof if practicable, (ii) not paying the same except
under protest with funds advanced by Lessee on an interest-free basis, if
protest is proper, and (iii) if payments are made, using reasonable efforts to
obtain a refund thereof in appropriate administrative and judicial proceedings;
provided, that Lessee shall not, without Lessor's consent, contest any Taxes
imposed against Lessor that are unrelated to the transactions contemplated by
the Agreement, provided further, that in no event shall Lessor settle any claim
for which Lessee has an indemnity obligation pursuant to Section 15 and this
Section 16 without Lessee's written consent, and provided further, that in each
such instance, Lessor shall not be required to undertake any contest or allow
Lessee to undertake any contest unless:

          (i)   Lessor shall not, at such time, be exercising its remedies under
Section 14 hereof;

          (ii)  prior to the commencement of any contest undertaken by Lessee or
any contest undertaken by Lessor, Lessee shall have delivered to Lessor a
written acknowledgment of its obligation to indemnify fully Lessor for Taxes
indemnified to the extent that the contest is not successful;

          (iii) Lessee shall have made all payments then due under this
Agreement, including, without limitation, such payments then due under Section
15 and this Section 16;

          (iv)  Lessee shall have provided Lessor with an opinion of legal
counsel reasonably acceptable to Lessor to the effect that a reasonable basis
exists to contest such claim and, prior to the commencement of any appeal of an
adverse judicial decision, with an opinion of such tax counsel to the effect
that a reasonable basis exists to appeal such adverse judicial decision (which
opinions shall be obtained at Lessee's sole cost and expense);

                                     16-5
<PAGE>

          (v) if such contest is to be initiated by the payment by Lessor of,
and the claiming of a refund for, such Taxes, Lessee shall have advanced to
Lessor sufficient funds (on an interest-free basis) to make such payments, and
if Lessor is to undertake the related contest, Lessee shall have each month
advanced to Lessor the Expenses of such contest for the following month,
provided, that Lessee shall indemnify Lessor for any adverse tax consequences
resulting from any such advance; and

          (vi)  such proceedings do not involve any risk of an imposition of any
material risk or danger of the sale, forfeiture or loss of the Aircraft or any
part thereof or the creation of any Lien other than a Lien for taxes not yet due
or being contested in good faith by appropriate proceedings, and for the payment
of which such reserves, if any, as are required to be provided under generally
accepted accounting principles have been provided.

     If Lessor shall obtain a refund of all or any part of such Taxes paid by
Lessee, Lessor shall pay Lessee the amount of such refund less the amount of any
Taxes payable by Lessor in respect of the receipt of such refund after giving
credit to Lessee for any interest received by Lessor with respect to such Taxes
and for any savings by Lessor in respect to any such Taxes by reason of any Tax
Benefits in respect of the payment of any such Taxes; provided that such amount
shall not be payable (x) before such time as Lessee shall have made all payments
or indemnities then due to or on behalf of Lessor under this Agreement, (y)
while Lessor is exercising its remedies under Section 14 hereof, or (z) to the
extent it exceeds the amount of all payments made by Lessee with respect to such
Taxes. If in addition to such refund Lessor shall receive an amount representing
interest on amount of such refund, Lessee shall be paid that proportion of such
interest which is fairly attributable to Taxes paid by Lessee prior to the
receipt of such refund; provided, that no amount shall be payable under this or
the preceding sentence during any period in which Lessor is exercising its
remedies under Section 14 hereof unless this Lease has terminated and Lessee has
paid all amounts due Lessor hereunder. If any refund or Tax Benefit is taken
into account under this paragraph and it is subsequently determined that Lessor
was not entitled thereto, the return or cancellation thereof shall be treated as
a Tax that is indemnifiable under this Section 16.

     Lessee shall, as provided above, indemnify Lessor for, or advance to
Lessor, the Expenses, absent manifest error in the amount or nature thereof.

     If Lessee neither requests that Lessor contest a Tax indemnified hereunder,
nor notifies Lessor that Lessee desires to contest such Tax, Lessor may, at its
expense (including all Expenses), in good faith contest the validity,
applicability or amount of such Tax; provided, that Lessor shall consult with
Lessee from time to time on the

               --------------------------------------------
Aircraft, including the Airframe or any of the Engines, shall be permitted, and
no assignment of the Aircraft or any of Lessee's rights under the Lease to any
other party shall be permitted in either case, without the prior written consent
of Lessor which consent, in the case of a sublease to a Certificated Air
Carrier, shall not be unreasonably withheld.

          18.3 Consolidation. Merger or Transfer by Lessee. Lessee shall not,
               -------------------------------------------
without the prior written consent of Lessor (which consent will not be

any Person.

          18.4  Limited Liability of Lessor. Notwithstanding anything herein
                ---------------------------
to the contrary, each and all of the representations, warranties, undertakings
and agreements herein made on the part of Lessor are made and intended not as
personal representations, warranties, undertakings and agreements of Investors
Asset Holding Corp. or for the purposes or with the intention of binding
Investors Asset Holding Corp. personally, but are made and intended for the
purpose of binding only the Trust Estate (as defined in the Trust Agreement),
and this Lease is executed and delivered by Investors Asset Holding Corp. solely
in the exercise of the powers expressly conferred upon Investors Asset Holding
Corp. as Owner Trustee under the Trust Agreement; and no personal liability or
personal responsibility is assumed by or shall at any time be asserted or
enforceable against Investors Asset Holding Corp. on account of any
representation, warranty, undertaking or agreement hereunder of Investors Asset

for its own willful misconduct or gross negligence) either express or implied,
all such personal liability, if any, being expressly waived and released by

however, that nothing contained in this Section shall be construed to limit the
liability of Investors Asset Holding Corp. in its individual capacity for any
breach of any representations, warranties or covenants made by Investors Asset
Holding Corp.

     SECTION 19. APPRAISALS.
                 -----------

          19.1 If an independent appraisal of Fair Market Rental Value or Fair
Market Sales Value, as the case may be is required pursuant to this Lease, then
the independent appraisal shall be arrived at by mutual agreement of two
nationally recognized, independent Aircraft appraisers, one chosen by Lessor and
one chosen by Lessee, or, if such appraisers cannot agree on the amount of such
appraisal, their appraisals shall be treated in the manner described in
Subsection 19.2 with an appraisal arrived at by a third nationally recognized,
independent Aircraft appraiser chosen by the mutual consent of such two
appraisers; provided, however, that if either party shall fail to appoint an
appraiser within 15 Business Days after a written request to do so by the other
party, or if such two appraisers cannot agree on the amount of such appraisal
within 20 Business Days after the date of the appointment of the second of such
appraisers and fail to appoint a third appraiser within seven Business Days
after the expiration of such 20-day period, then either party may apply to the
American Arbitration Association located in Boston, Massachusetts to make such
appointment.

          19.2 If two appraisers are chosen as provided in Subsection 19.1, and
such appraisers agree on the value, such value shall be final and binding upon
Lessor and Lessee. If three appraisers shall be appointed and the difference
between the determination which is further from the middle determination is more
than 125% of the difference between the middle determination and the third
determination, then such further determination shall be excluded, the remaining
two determinations shall be averaged, and a value equal to such average shall be
final and binding upon Lessor and Lessee. Otherwise a value equal to the average
of all three determinations shall be final and binding upon Lessor and Lessee.
