Airframe pursuant to Section 11(a)(i) hereof) together with the (i) two IAE

            "Appraisal Procedure" shall mean the following procedure for

would be obtained in an arm's-length transaction between an informed and willing
seller or lessor, as the case may be, and an informed and willing buyer or
lessee, as the case may be, both under no compulsion to sell and purchase or to
lease (and other than a lessee in possession or a used equipment scrap dealer),
as the case may be, as such value is determined by an appraisal which assumes:
(i) that such Aircraft, such Airframe, such Engine or such Part is unencumbered
by this Lease (or any sublease) or any of the other Operative Documents or any
of the Financing Documents and the terms thereof; (ii) that such Aircraft,
Airframe, Engine or Part has been maintained in all respects in accordance with

such Aircraft, Airframe, Engine or Part meets the return conditions specified in
Section 16 and Exhibit E (whether or not in fact meeting such conditions) and
(iv) that Lessee has removed the Removable Parts entitled to be removed under
Section 9(b) (it being agreed that no such removal is permitted in connection
with an appraisal pursuant to Section 18) and replaced any part which was
removed from the Aircraft as a result of such Removable Part being installed;
provided, however, that costs of removal from the location of current use and
costs of sale shall not be a consideration in determining such value except in
connection with any determination of "fair market sales value" or "fair market
rental value" pursuant to Section 18; and provided, further, that any
determination of "fair market sales value" or "fair market rental value"
pursuant to Section 18 shall be on an "as is, where is" basis in its actual
condition and location subject to this Lease and any sublease and any and all
Liens thereon (other than a Lessor's Lien or Lenders' Lien). Lessor and Lessee

pursuant to Section 18 in which case only Lessor shall select such appraiser
(which appraiser does not have to be acceptable to Lessee), select an
independent nationally-recognized aircraft appraiser, mutually acceptable to
each of them, who shall make the determination as to the "fair market sales
value" or "fair market rental value" of such Aircraft, Airframe, Engine or Part
for which such appraisal is to be conducted. If Lessor and Lessee fail to agree
upon a mutually acceptable appraiser within ten (10) days, then each of Lessor
and Lessee shall select an appraiser and such determination shall be made by
such appraisers (if either party shall fail to appoint an appraiser within ten
(10) days after notice from the other party of the selection of its appraiser,
then the appraisal made by the other party's appraiser shall be determinative).
If the two appraisers chosen pursuant to the preceding sentence fail to agree
upon a determination of the "fair market sales value" or "fair market rental
value" of such Aircraft, Airframe, Engine or Part within twenty (20) days after
their appointment, then such appraisers shall mutually choose a third appraiser
within ten (10) days thereafter, provided that if such appraisers fail to
mutually choose a third appraiser within said 10-day period, such appointment
shall be made by the American Arbitration Association (or any successor) in New
York, New York, and the three appraisers so chosen shall each make such
determination. The appraisal determined by each of the three appraisers chosen
pursuant to the preceding sentence shall be averaged and the appraisal furthest
from the average of the three appraisals shall be disregarded. The appraisal
determined by each of the two remaining appraisers shall be averaged and such
average shall be the appraised "fair market sales value" or "fair market rental
value" of such Aircraft, Airframe, Engine or Part. Lessee shall bear all the
fees and expenses of the Appraisal Procedure.

                                      -23-
   25
to constitute a guaranty of the value, utility or useful life of the Aircraft or
a guaranty in respect of interest, principal or any other amounts payable in
respect of or under the Equipment Notes.

            (c) Date, Place and Method of Payment. If any date on which a
payment of Rent becomes due and payable is not a Business Day, the Rent
otherwise due on such date shall be due and payable on the next succeeding
Business Day. All Basic Rent, Renewal Rent and Supplemental Rent payable under
this Lease shall be paid by wire transfer in immediately available currency of
the United States of America, no later than 12:00 p.m. (noon), New York City
time, on the date payable hereunder, and, so long as the Lien of the Indenture
shall not have been discharged, to or as directed by Indenture Trustee in
accordance with the payment instructions set forth in Exhibit C hereto or at
such other address in the City of New York or Hartford, Connecticut as Indenture
Trustee may direct by thirty (30) days prior written notice to Lessee, except
for all Excepted Payments. All Excepted Payments, and, upon discharge of the
Lien of the Indenture, all payments of Rent thereafter made hereunder, shall be
paid in such immediately available funds no later than 12:00 p.m. (noon), New
York City time, on the date payable hereunder, to Lessor or to Owner
Participant, as appropriate, in accordance with the payment instructions set
forth in Exhibit C or at such other address as Lessor may direct by thirty (30)
days prior written notice to Lessee.

            (d) Prohibition Against Setoff, Counterclaim, Etc. This Lease is a
net lease. Lessee's obligations to pay all Rent and to perform all other
obligations hereunder are absolute and unconditional and shall not be affected
or reduced by any circumstances, including, without limitation, (i) any setoff,
counterclaim, recoupment, defense, or other right which Lessee may have against
Lessor, Original Head Lessee, Owner Participant, Indenture Trustee, any Note
Holder, any Manufacturer, any Person providing services with respect to the
Aircraft, or any other Person, for any reason whatsoever (whether in connection
with the transactions contemplated hereby or otherwise), including, without
limitation, any breach by Lessor of its representations, warranties or covenants
contained herein or in the other Operative Documents; (ii) any defect in the
title, airworthiness, eligibility for registration under the Federal Aviation
Act, condition, design, operation, or fitness for use of, or any damage to or
loss or destruction of, the Aircraft (subject to the provisions of Section


                                      -24-
   26
11(a)(ii) hereof), any interruption or cessation in the use of or possession
thereof by or availability to Lessee for any reason whatsoever, whether arising
out of or related to an act or omission of Lessee, Lessor, Original Head Lessee,
Owner Participant, Indenture Trustee, any Note Holder, any Manufacturer, any
Person providing services with respect to the Aircraft or any other Person;
(iii) any Liens with respect to the Aircraft; (iv) the invalidity or
unenforceability or lack of due authorization or other infirmity of this Lease
or any sublease or any absence of right, power or authority of Lessor, Original
Head Lessee, Lessee or Indenture Trustee to enter into this Lease or the
Indenture, as the case may be; (v) any insolvency, bankruptcy, reorganization,
or similar proceedings by or against Lessor, Original Head Lessee, Lessee, any
sublessee, Indenture Trustee or any Note Holder; (vi) any Taxes or (vii) any
other circumstance or happening of any nature whatsoever, whether or not similar
to any of the foregoing; it being the expressed intention of Lessor and Lessee
that all Rent payable hereunder shall be payable in all events, unless the
obligation to pay the same shall be terminated pursuant to the express
provisions of this Agreement.

            Except as expressly set forth elsewhere in this Agreement, Lessee
hereby waives, to the extent permitted by applicable Law, any and all rights
which it may now have or which at any time hereafter may be conferred upon it,
by statute or otherwise, to terminate, abate, cancel, quit, reduce, defer,
suspend or surrender this Lease or the Aircraft or any obligation imposed upon
Lessee hereunder or under the other Operative Documents (including, without
limitation, payment of Rent), except in accordance with the terms hereof.

            Each payment of Rent made by Lessee shall be final. Lessee will not
seek to recover all or any part of any payment of Rent for any reason whatsoever
except manifest error.

            If for any reason whatsoever this Lease shall be terminated in whole
or in part by operation of Law, except as specifically provided herein, Lessee
waives all rights (if any) to any diminution in its Rent obligations hereunder
and nonetheless agrees to pay to Indenture Trustee or Lessor as provided in
Section 4(c) hereof an amount equal to each Basic Rent or Renewal Rent, as the
case may be, payment and any Supplemental Rent payment at the time such payments
would have become due and payable in accordance with the terms hereof had this
Lease not been terminated in whole or


                                      -25-
   27
in part, and so long as such payments are made and all other terms and
conditions hereof are complied with by Lessee, Lessor and Lessee will deem this
Lease to remain in full force and effect.

            The foregoing shall not, however, be construed as a waiver of
Lessee's other rights to seek damages, specific performance, other remedies at
law or equity or any combination thereof, as against the Original Head Lessee,
Lessor, Indenture Trustee or any other Person having an interest herein through
the Original Head Lessee, Lessor, Indenture Trustee or any other Person as shall
be liable therefor, on account of any failure of the Original Head Lessee,
Lessor, Indenture Trustee or any other such Person to perform its express
obligations under this Lease and the other Operative Documents, or to enforce
any judgment obtained therefor.

            The representations, warranties and covenants of Lessor under
Sections 5(a) and 5(b) and this Section 5(c)


                                      -27-
   29
shall survive the execution and delivery of this Lease and the delivery of the
Aircraft and the Restatement Date.

            (d) Suppliers' Warranties. So long as a Default or an Event of
Default has not occurred and is continuing and provided that the Aircraft
continues to be maintained, modified and repaired as required hereunder, Lessor
hereby assigns or, if by their terms not assignable, agrees otherwise to make
available to Lessee the right to exercise in Lessee's name such rights as Lessor
may have or may subsequently obtain (but without representation or warranty by
or recourse to Lessor) with respect to any product warranty, service life
policy, trademark, patent or copyright infringement indemnity, or airframe or
propulsion system performance guaranty, of Airbus Industrie, the Manufacturer's
Subsidiary, IAE or any subcontractor or vendor with respect thereto under the
Purchase Agreement (except those which were given directly to Parent, the
Original Head Lessee or any of their Affiliates and are not directly related to
the operator's use of the Aircraft), to the extent that the same may be assigned
or otherwise made available to Lessee, and Lessor agrees to exert its reasonable
efforts, at Lessee's expense and upon its request, to enforce such rights as
Lessor may have with respect thereto for the benefit of Lessee; provided,
however, that upon and during the continuance of a Default or an Event of
Default, such assignment or other rights which are otherwise made available to
Lessee shall immediately and automatically without further action be deemed
cancelled and, to the extent of any remaining interest held by Lessee, deemed
reassigned to Lessor and all such rights shall revert to Lessor automatically
including all claims thereunder whether or not perfected and all amounts payable
shall be paid to and held by Lessor. In no event, however, shall Lessee have any
right to amend, supplement or otherwise modify the Purchase Agreement (by change
order or otherwise). In connection with the foregoing, Lessee agrees to be bound
by and comply with all applicable terms, conditions and limitations of the
provisions of the Purchase Agreement.

            Section 6. Possession and Use.

            (a) Possession.

                  (i) Lease, Assignment and Transfer. LESSEE WILL NOT ASSIGN
THIS LEASE OR ANY RIGHTS OR OBLIGATIONS HEREUNDER OR INTEREST HEREIN (EXCEPT AS
PROVIDED IN SECTION 8(e) BELOW) OR SUBLEASE, WET LEASE OR OTHERWISE IN ANY

   30
MANNER TRANSFER, DELIVER OR RELINQUISH POSSESSION OR USE OF THE AIRCRAFT,
AIRFRAME OR ANY ENGINE OR INSTALL ANY ENGINE OR PERMIT ANY ENGINE TO BE
INSTALLED ON ANY AIRFRAME OTHER THAN THE AIRFRAME; provided, that, so long as no
Event of Default or Default shall have occurred and be continuing or would
result therefrom and so long as the action to be taken shall not adversely
affect Lessor's title to or other interest in, or the Lien of the Indenture on,
the Aircraft, the Airframe or either of the Engines or this Lease or the
insurance required to be maintained hereunder and Lessee is otherwise in full
compliance with Section 12, and so long as all necessary approvals of the FAA
and any other Governmental Entity having jurisdiction have been obtained, then
Lessee, without the prior written consent of Lessor, may, only to the extent
provided below and subject to the limitations of Sections 6(a)(ii) and 6(a)(iii)
below:

                  (1) subject any Engine to a normal interchange, maintenance,
            servicing or pooling agreement or similar arrangement with a
            Permitted Sublessee, in each case customary in the airline industry
            of which Lessee is a part and entered into in the ordinary course of
            its business; provided that no transfer of the registration of any
            Engine shall be effected in connection therewith; and provided,
            further, that (A) no such agreement or arrangement contemplates,
            results in or requires the transfer of title to any 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 an
            Event of Loss with respect to such Engine and not an Event of
            Default and Lessee shall comply with Section 11(b) hereof in respect
            thereof;

                  (2) deliver possession of the Aircraft, the Airframe or any
            Engine to the manufacturer thereof, or in accordance with the

            on such Aircraft, Airframe or Engine or any part thereof or for
            alterations or modifications in or additions to such Aircraft,
            Airframe or Engine to the extent required or permitted by the terms
            of Section 9 hereof;

                  (3) transfer possession of the Aircraft or the Airframe to the
            United States of America or any instrumentality or agency thereof
            pursuant to a sublease;


                                      -29-
   31
                  (4) (i) subject the Airframe to the Civil Reserve Air Fleet
            Program and transfer possession of the Airframe or any Engine to the
            United States Government pursuant to the Civil Reserve Air Fleet
            Program, so long as Lessee shall promptly notify Lessor upon
            transferring possession of the Airframe or any Engine to the United
            States Government pursuant to the Civil Reserve Air Fleet Program
            and provide Lessor with the name and address of the Contracting
            Office Representative for the Military Airlift Command of the United
            States Air Force to whom notices must be given; or

                  (ii) subject the Airframe to (a) a service contract with the
            United States Government, a copy of which shall be provided to
            Lessor, providing for possession to be held by the United States
            Government for a period not extending beyond the end of the Term, or
            (b) a requisition for use by the United States Government not
            constituting an Event of Loss;

                  (5) install an Engine on an airframe (other than the Airframe)
            owned by Lessee free and clear of all Liens except (A) Permitted
            Liens and Liens which apply only to engines (other than the
            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 (B) the rights of participants under normal interchange
            agreements which are customary in the airline industry and do not
            contemplate, permit, result in or require the transfer of title to
            the airframe or engines installed thereon;

                  (6) install an Engine on an airframe leased to Lessee or owned
            by Lessee subject to a conditional sale or other security agreement;
            provided that: (A) such airframe is free and clear of all Liens
            except the rights of the parties to the lease or conditional sale or
            other security agreement covering such airframe and except Liens of
            the type permitted by clauses (A) and (B) of Section 6(a)(i)(5) and
            the Lien of any mortgage which provides that each Engine leased to
            Lessee hereby shall not become subject to the Lien thereof or to any
            rights of any party thereunder other than Lessee (with respect to
            Lessee's rights expressly granted hereunder), notwithstanding the
            installation of such Engine on any airframe subject to the Lien of
            such mortgage, unless and until Lessee shall become the


                                      -30-
   32
            owner of such Engine and Lessor shall have no further interest
            therein, all pursuant to the express terms of this Lease; and (B)
            there shall be in effect a written agreement of the lessor or
            secured party of such airframe (which may be contained in the lease
            or conditional sale or other security agreement covering such
            airframe) substantially similar in effect to the agreement of Lessor
            in Section 6(b) below whereby such lessor or secured party
            effectively and expressly agrees that neither it nor its successors
            or assigns will acquire or claim any right, title or interest in any
            Engine by reason of such Engine being installed on such airframe at
            any time while such Engine is subject to this Lease or is owned by
            Lessor, and a copy of such agreement shall be provided to Lessor
            upon written request;

                  (7) install an Engine on an airframe owned by Lessee, leased
            to Lessee or purchased by Lessee subject to a conditional sale or
            other security agreement under circumstances where neither Section
            6(a)(i)(5) or Section 6(a)(i)(6) is applicable; provided that such
            installation shall be deemed an Event of Loss with respect to such
            Engine and Lessee shall comply with Section 11(b) hereof in respect
            thereof, Lessor not intending hereby to waive any right or interest
            it may have to or in such Engine under applicable Law until
            compliance by Lessee with such Section 11(b);

                  (8) enter into a Wet Lease for the Aircraft or the Airframe
            and engines installed thereon in the ordinary course of Lessee's
            business for a period not extending beyond the Term; provided that
            if Lessee shall enter into any Wet Lease for a period of more than
            six months (including renewal options) Lessee shall provide to
            Lessor written notice of such Wet Lease (such notice to be given at
            least ten (10) Business Days prior to entering into such Wet Lease);
            or

                  (9) sublease the Aircraft or the Airframe to any Permitted
            Sublessee on the terms and conditions set forth in Section 6(a)(iii)
            below.

transfer pursuant to Section 6(a)(i):

                  (1) the rights of any transferee that receives possession by
            reason of a transfer permitted by Section


                                      -31-
   33
            6(a) hereof (other than the transfer of an Engine which is deemed to
            have been an Event of Loss) and any Wet Lease shall be expressly
            subject and subordinate to all the terms of this Lease and the Lien
            of the Indenture (if it has not been discharged);

                  (2) Lessee's obligations hereunder and under the other
            Operative Documents shall continue in full force and effect and
            Lessee shall remain primarily liable hereunder for the performance
            of all of the terms of this Lease to the same extent as if such
            transfer had not occurred and no provision of this Lease shall be
            deemed a waiver of the Lessor's rights hereunder or under the other
            Operative Documents nor discharge or diminish any of Lessee's
            obligations hereunder or under the other Operative Documents;

                  (3) During the Restricted Use Period, no Wet Lease, Permitted
            Sublease or other relinquishment of possession of the Aircraft, the
            Airframe or any Engine pursuant to the terms of this Section 6(a)
            shall be permitted if such Wet Lease, Permitted Sublease or other
            relinquishment of possession would cause the Aircraft, the Airframe
            or such Engine to be "tax-exempt use property" within the meaning of
            Section 168(h) of the Code or cease to be "Section 38 property"
            within the meaning of Section 48(a) of the Code (as determined after
            the application of Section 47(a)(7) of the Code);

                  (4) The term of any transfer, Wet Lease, Permitted Sublease or
            other relinquishment of possession shall not extend beyond the Basic
            Term or the Renewal Term (if Lessee shall have exercised its option
            to renew this Lease in accordance with the terms hereof);

                  (5) No transfer, Wet Lease, Permitted Sublease or other
            relinquishment of possession of the Aircraft, the Airframe or any
            Engine shall in any way discharge or diminish any of Lessee's
            obligations to Lessor or any other Person hereunder for which
            obligations Lessee shall remain primarily liable;

                  (6) The sublessee under any Permitted Sublease, in its consent
            thereto, shall confirm that from and after the occurrence and
            continuance of an Event of Default and, unless an Event of Default
            specified in Section 17(e), (f) or (g) of this Lease has occurred
            and is continuing, this Lease being deemed or declared


                                      -32-
   34
            in default, Lessor (and, so long as the Lien of the Indenture shall
            not have been discharged, Indenture Trustee) shall be entitled to
            enforce directly and in its own name all representations,
            warranties, indemnities, covenants and agreements under the
            applicable Permitted Sublease; and

                  (7) Each Permitted Sublease shall (A) provide that (I) the
            Aircraft or Airframe may not be operated or used other than as
            provided in this Lease and shall be maintained and operated as
            required hereunder, (II) Lessor may avoid or terminate such sublease
            following an Event of Default hereunder and (III) to the extent not
            accomplished by an assignment of the Permitted Sublease, upon the
            occurrence of an Event of Default hereunder, Lessee's rights under
            such Permitted Sublease shall automatically be deemed assigned to
            Lessor; and (B) be a "net lease" in accordance with industry
            practice and shall be comparable to, or more restrictive than, this
            Lease and under such Permitted Sublease (except a sublease to the
            United States Government or a Foreign Air Carrier after the
            Restricted Use Period), Lessee as lessor under such Permitted
            Sublease, must be entitled to the same benefits under 11 U.S.C.
            Section 1110 as Lessor is entitled hereunder and such Permitted
            Sublease shall contain provisions regarding such Section 1110 which
            are substantially the same as the related provisions of this Lease.
            In addition, from and after the occurrence and continuance of an
            Event of Default, all rent and other amounts payable by the
            Permitted Sublessee under such Permitted Sublease shall be paid
            directly to Indenture Trustee and, upon discharge of the Lien of the
            Indenture, to Lessor.

                      (iii) Permitted Subleases. With respect to any sublease
pursuant to Sections 6(a)(i)(3) or (4) (to the extent permitted by Law) or
Section 6(a)(i)(9) above:

                  (1) Lessee may sublease the Aircraft or the Airframe to a
            Permitted Sublessee (each of which shall constitute a "Permitted
            Sublease") if (A) in any such case, the Permitted Sublessee under
            such sublease is not subject to a proceeding or final order under
            applicable bankruptcy, insolvency or reorganization laws on the date
            such sublease is entered into, (B) in the event that the Permitted
            Sublessee under such sublease is a Foreign Air Carrier (other than a
            Foreign Air Carrier principally based in Taiwan), the United


                                      -33-
   35
            States maintains diplomatic relations with the country in which such
            proposed Permitted Sublessee is principally based at the time such
            sublease is entered into (or, in the case of a sublease to a
            proposed Permitted Sublessee principally based in Taiwan, maintains
            diplomatic relations at least as good as those in effect on the
            Restatement Date) and (C) in the event that the Permitted Sublessee
            under such sublease is a Foreign Air Carrier, Lessor and the
            Indenture Trustee shall have received an opinion of counsel to
            Lessee, in form and substance reasonably satisfactory to Owner
            Participant and the Indenture Trustee, to the effect that (I) the
            terms of the proposed sublease will be legal, valid, binding and
            (subject to customary exceptions in foreign opinions generally)
            enforceable against the proposed Permitted Sublessee in the country
            in which the Permitted Sublessee is principally based, (II) there
            exist no possessory rights in favor of the Permitted Sublessee under
            such sublease under the laws of such Permitted Sublessee's country
            of domicile that would, upon bankruptcy or insolvency of or other
            default by Lessee, prevent the return or repossession of the
            Aircraft in accordance with the terms of this Lease, (III) (unless
            Lessee shall have agreed or is required to provide insurance
            covering the risk of requisition of use of the Aircraft by the
            government of the country of such Permitted Sublessee's country of
            domicile) the laws of such Permitted Sublessee's country of domicile
            require fair compensation by the government of such jurisdiction
            payable in currency freely convertible into dollars for the loss of
            use of the Aircraft in the event of the requisition by such
            government of such use, (IV) the Permitted Sublessee is either not
            entitled to sovereign immunity, or has effectively waived such
            sovereign immunity, with respect to its rights and obligations under
            the proposed sublease; (V) the laws of such Permitted Sublessee's
            country of domicile would give recognition to Lessor's title to the
            Aircraft, to the registry of the Aircraft in the name of the Lessor
            (or Lessee, as "lessee", or the proposed Permitted Sublessee, as
            "sublessee", as appropriate) and to the Lien of the Indenture; (VI)
            it is not necessary under the laws of such Permitted Sublessee's
            country of domicile, solely as a consequence of such subleasing and
            without giving effect to any other activity of Owner Participant,
            Owner Trustee or Indenture Trustee or any Affiliate thereof, as the
            case may be, for the Owner Trustee, the Owner Participant or the
            Indenture Trustee to qualify


                                      -34-
   36
            to do business in such jurisdiction and (VII) if the Owner
            Participant so requests, (x) under the laws of such Permitted
            Sublessee's country of domicile there is no tort liability of the
            owner of an aircraft not in possession thereof (it being agreed that
            in the event this opinion cannot be given in a form reasonably
            satisfactory to Owner Participant, such opinion shall be waived if
            insurance reasonably satisfactory to Owner Participant is provided
            to cover such risk), and (y) such other matters as the Owner
            Participant reasonably requests, provided, however, that no sublease
            shall extend beyond the expiration of the Basic Term or any Renewal
            Term then in effect.

                  Any Permitted Sublease shall expressly provide that the rights
of any Permitted Sublessee shall be expressly subject and subordinate to all the
terms of this Lease and to the Lien of the Indenture (if it has not been
discharged), including, without limitation, the covenants contained in Sections
6(c), 6(d) and 6(e) hereof and Lessor's rights to repossession pursuant to
Section 18 hereof and to avoid or terminate such Permitted Sublease upon such
repossession, and Lessee shall remain primarily liable hereunder for the
performance of all of the terms of this Lease to the same extent as if such
Permitted Sublease had not occurred. No Permitted Sublease shall in any way
discharge or diminish any of Lessee's obligations to Lessor hereunder or under
the other Operative Documents or constitute a waiver of Lessor's rights or
remedies hereunder or under the other Operative Documents, and such rights shall
continue as if such Permitted Sublease had not occurred. Any Permitted Sublease
shall expressly prohibit any further sub-sublease or assignment or any other
similar transfer of the Aircraft, Airframe or any Engine or rights thereto by
the Permitted Sublessee. Lessee shall provide to the Owner Participant and the
Indenture Trustee (i) written notice of any Permitted Sublease hereunder (such
notice to be given not later than ten Business Days prior to entering into any
Permitted Sublease with any proposed Permitted Sublessee), and (ii) a copy of
each Permitted Sublease together with an assignment, as security for Lessee's
obligations hereunder, of such Permitted Sublease, and if Lessor or the
Indenture Trustee so requests, a consent thereto from such Permitted Sublessee,
substantially in the form of Exhibit F-3 hereto, within ten (10) Business Days
following the effective date of such Permitted Sublease.

                  (b) Reciprocal Recognition of Rights. In the event the lessor
or secured party of any airframe leased to


                                      -35-
   37
Lessee (or a Permitted Sublessee) or owned by Lessee (or a Permitted Sublessee)
is subject to a conditional sale or other security agreement in accordance with
Section 6(a)(i)(6) hereof, and the lease or conditional sale or other security
agreement covering such airframe also covers an engine or engines owned by the
lessor under such lease or subject to a security interest in favor of the
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 subject to such lease or
conditional sale or other security agreement and owned by such lessor or subject
to a security interest in favor of such secured party. Lessor also hereby agrees
for the benefit of the mortgagee under any mortgage complying with Section
6(a)(i)(6) hereof, relating to installation of an Engine on an airframe leased
to Lessee (or a Permitted Sublessee), that Lessor will not acquire or claim, as
against such mortgagee, any right, title or interest in any engine subject to
the lien of such mortgage as the result of such engine being installed on the
Airframe at any time while such engine is subject to the lien of such mortgage.

                  (c) Lawful Insured Operations. Lessee will not permit the
Aircraft, the Airframe or any Engine to be serviced, repaired, maintained, used
or operated in violation of any Law of any Governmental Entity having
jurisdiction, or contrary to the Manufacturers' operating manuals or
instructions, or in violation of any airworthiness certificate or limitation,
license or registration issued by any such authority or any manufacturer's
specifications, service bulletins or other requirements, including, without
limitation, any manufacturer's requirements as may be applicable to keep in full
force and effect each material warranty, product or performance guaranty,
service life policy or the like, in each case, to the extent made mandatory for
Part 121 operators similarly situated to Lessee or the Permitted Sublessee if
the Aircraft is registered with the FAA, or the applicable laws of any other
jurisdiction in which the Aircraft may then be registered in accordance with
Section 11 of the Refunding Agreement, unless the validity thereof is being
contested in good faith and by appropriate proceedings, but only so long as such
proceedings do not involve any danger of sale, forfeiture or loss of the
Aircraft or impair the interest of Lessor therein or impair the validity or
priority of the


                                      -36-
   38
Lien of the Indenture or result in a risk of criminal liability of Lessor, Owner
Participant or Indenture Trustee and are not inconsistent with any insurance
required to be maintained by Lessee hereunder. In the event that such Law or
other requirement requires alteration of the Aircraft during the Basic Term or
the then-current Renewal Term, Lessee shall comply therewith at its sole expense
and shall maintain the same in proper condition for operation under such Laws
and other requirements. Lessee shall not operate in any manner or locate in any
place the Aircraft, or suffer or permit the Aircraft to be operated by a
Permitted Sublessee or otherwise in any manner or located by a Permitted
Sublessee or otherwise in any place (i) unless the Aircraft is covered by
insurance or United States Government indemnity as required by the provisions
hereof or (ii) contrary to the terms of such insurance or United States
Government indemnity. Lessee also agrees not to operate or locate the Aircraft
or suffer or permit the Aircraft to be operated or located in any area excluded
from coverage by any insurance policy issued pursuant to the requirements of
this Lease or in any war zone unless insured or indemnified by the United States
of America therefor, except in the case of operation pursuant to a sublease or
contract with, or as a result of a requisition (not constituting an Event of
Loss) by, the United States of America, and then only if Lessee has obtained
insurance or an indemnity (in lieu of such insurance) from the United States of
America covering such risks, in the amounts and otherwise as required by this
Lease.

                  (d) Maintenance. Lessee, at its own cost and expense, shall:
(i) perform or cause to be performed all service, repair, maintenance, overhaul,
inspections, alterations, modifications, and testing (A) in accordance with good
airline industry practice and in such manner to provide complete data and
documentation necessary to substantiate certification, (B) as may be necessary
and required under, and in compliance with, applicable Law, including, without
limitation, FAA rules, regulations and other requirements, any other applicable
rules, regulations and requirements by any other applicable Governmental Entity,
the Maintenance Program, airworthiness directives having a compliance date
during the Term, and the service bulletins and other requirements of any
manufacturer, including, without limitation, such requirements as may be
applicable to keep in full force and effect any and all material warranties,
product and performance guaranties, service life policies, indemnities or the
like, (C) except during any period that a Permitted Sublease is in effect, in


                                      -37-
   39
the same manner and with the same care, including regard for the status and
technical condition of the Aircraft, as shall be the case with respect to
similar aircraft and engines owned by Lessee without discrimination and as if
Lessee owned the Aircraft and was going to use the Aircraft in continued regular
customer service after the expiration of the Term, and consistent with good
industry practice, and during any period in which a Permitted Sublease is in
effect, in the same manner and with the same care, including regard for the
status and technical condition of the Aircraft, as shall be the case with
respect to similar aircraft and engines owned by such Permitted Sublessee
without discrimination and as if the Permitted Sublessee owned the Aircraft and
was going to use the Aircraft in continued regular customer service after the
expiration of the Permitted Sublease, and consistent with good industry
practice, provided, however, that in all circumstances the Aircraft shall be
maintained by Lessee (or any Permitted Sublessee) in accordance with maintenance
standards required by, or substantially equivalent to those required by the
central civil aviation authority of the country of registry, and, to the extent
not inconsistent therewith, the FAA and (D) so as to keep the Aircraft in as
good a condition as when delivered to Lessee, ordinary wear and tear excepted,
and in good operating condition; (ii) keep the Aircraft or cause the Aircraft to
be kept in such condition as is necessary to enable the airworthiness
certification of such Aircraft to be maintained in good standing at all times
under the Federal Aviation Act and any other applicable law, or the applicable
laws of any other jurisdiction in which the Aircraft may be registered in
accordance with Section 11 of the Refunding Agreement (provided that if any
grounding is fleetwide in nature and so long as Lessee or a Permitted Sublessee
is contesting in good faith such grounding, Lessee shall not be deemed in
violation of this maintenance covenant); and (iii) maintain in English all
records, logs and other materials required by, and in a manner acceptable to,
the FAA or any other Governmental Entity having jurisdiction and as provided
under the Maintenance Program and Lessee's recordkeeping policies.

            (e) Registration and Insignia. Lessee shall cause the Aircraft at
all times, at its expense, to be duly registered during the Restricted Use
Period and, subject to Section 11 of the Refunding Agreement, thereafter under
the Federal Aviation Act in the name of Lessor or any successor or assignee, so
long as (i) while the Aircraft is registered under the Federal Aviation Act,
each of the Lessor or its successors or assigns is a "citizen of the United
States" as


                                      -38-
   40
defined in Section 40102(a)(15) of the Federal Aviation Act and (ii) the
applicable parties to the Refunding Agreement cooperate with Lessee with respect
thereto as reasonably requested by Lessee. Lessee shall not register the
Aircraft or permit the Aircraft to be registered under any Laws other than the
Federal Aviation Act at any time except as provided in Section 11 of the
Refunding Agreement and shall cause the Indenture to be duly recorded and
maintained of record as a duly perfected mortgage on the Aircraft and this Lease
at all times. At any time after the Restricted Use Period, Lessor, upon
compliance with all of the terms of Section 11 of the Refunding Agreement,
shall, at the request and sole expense of Lessee, cooperate with Lessee to take
all actions reasonably required to change the registration of the Aircraft to
another country.

            Lessee agrees at its expense to place such appropriate insignia,
plates and other identification ("Lease Identification") in the cockpit of the
Aircraft and on each Engine showing title thereto and the Lien of the Indenture
as designated by Lessor and as Lessor may from time to time reasonably request.
Unless otherwise requested, upon delivery of the Aircraft, Lessee shall fasten
or cause to be fastened in the cockpit of the Airframe in a location reasonably
adjacent to and not less prominent than the airworthiness certificate for the
Aircraft, and on each Engine (if not prohibited by applicable Law), a Lease
Identification in the form set forth in Exhibit C hereto or with any other
appropriate information in any other form subsequently designated by Lessor to
Lessee. Except as provided herein, Lessee will not allow the name of any Person
to be placed on the Aircraft or either Engine as a designation that would be
reasonably interpreted as a claim of ownership or Lien; provided, however, that
Lessee may cause the Airframe and Engines to have placed thereon the customary
colors and insignia of Lessee or any Permitted Sublessee under a Permitted
Sublease.

            Section 7. Inspection.

            During the Term of this Lease, Lessee shall furnish to Lessor, Owner
Participant and Indenture Trustee such information concerning the location,
condition, use and operation of the Aircraft as Lessor, Owner Participant or
Indenture Trustee may reasonably request. Lessee shall permit, or cause any
sublessee to permit, any person designated by Lessor, Owner Participant or
Indenture Trustee on reasonable prior notice at reasonable times to visit,


                                      -39-
   41
inspect and survey the Aircraft (including, without limitation, a visual "walk
around" inspection which may include going on board the Aircraft, and inspecting
the Aircraft during maintenance checks when panels and bays are open and subject
to view), its condition, use, and operation, and the records maintained in
connection therewith, and to visit and inspect the properties and to discuss the
affairs, finances and accounts of Lessee with the principal officers of Lessee,
provided, that so long as no Default or Event of Default has occurred hereunder
inspections shall be endeavored to be performed during regularly scheduled
maintenance checks of the Aircraft. Each such inspection or survey shall be
conducted so as to not unreasonably interfere with the business of Lessee or the
maintenance or operation of the Aircraft. Upon Lessor's, Owner Participant's or
Indenture Trustee's request, Lessee will notify such Person of the next
scheduled maintenance check for the Airframe or any Engine. Lessor, Owner
Participant and Indenture Trustee shall have no duty to make any such inspection
and shall not incur any liability or obligation by reason of not making any such
inspection. Lessor's, Owner Participant's or Indenture Trustee's failure to
object to any condition or procedure observed or observable in the course of an
inspection hereunder shall not be deemed to waive or modify any of the terms of
this Lease with respect to such condition or procedure.

            Section 8. Additional Covenants of Lessee.

            Lessee covenants and agrees that:

            (a) Financial Information. Lessee agrees to furnish Lessor, until
the expiration or other termination of the Term of this Lease, the following:

                  (i) within sixty (60) days following the end of each quarter
of Lessee's fiscal year, except the last such quarter of such year, commencing
after the Restatement Date, a copy of Lessee's Quarterly Report on Form 10-Q as
filed with the Securities and Exchange Commission or, if Lessee no longer files
such report, an unaudited consolidated balance sheet of Lessee and its
consolidated subsidiaries prepared by it as of the close of the period ended,
together with the related statements of income and cash flows for such period,
and in each case certified by a Responsible Officer of Lessee as having been
prepared in accordance with GAAP and as fairly presenting the financial
condition and results of operations and changes in financial


                                      -40-
   42
position for such period then ended in accordance with such principles and
practices (subject to normal year-end audit adjustments);

                  (ii) within one hundred five (105) days after the close of
each fiscal year of Lessee, a copy of Lessee's Annual Report on Form 10-K as
filed with the Securities and Exchange Commission or, if Lessee no longer files
such reports, an audited consolidated balance sheet, income statement, and cash
flow statement of Lessee and its consolidated subsidiaries, as of the close of
such fiscal year, and in each case as certified by independent public
accountants, including their certificate and accompanying comments, as having
been prepared in accordance with GAAP and as fairly presenting the financial
condition and results of operations and changes in financial position for such
period then ended in accordance with such principles and practices, without
qualification as to the scope of the audit or non-conformity with GAAP;

                  (iii) promptly upon their becoming available, copies of all
reports on Form 8-K filed by Lessee under the Securities Exchange Act of 1934,
as amended, and each other statement, report or circular (other than the
exhibits thereto and any registration statements on Form S-8 or its equivalent)
generally distributed to creditors or shareholders;

                  (iv) prior to the expiration date of each policy of insurance
required to be maintained hereunder, a certificate signed by the Approved Broker
of Lessee as to the due compliance with the insurance provisions of Section 12
hereof with respect to the Aircraft, together with certificates of insurance
evidencing such insurance and the opinion provided for in Section 12(f);

                  (v) together with each set of financial statements referred to
in clauses (i) and (ii), a certificate signed by a Responsible Officer of
Lessee, to the effect that such officer has reviewed the relevant terms of this
Lease and has made, or caused to be made under his or her supervision, a review
of the transactions and condition of Lessee during the accounting period covered
by such financial statements, and that such review has not disclosed the
existence during such accounting period, nor does such officer have any
knowledge of the existence, as at the date of such certificate, of any condition
or event which constitutes a Default or an Event of Default, or, if such
condition or event which constitutes a Default or an


                                      -41-
   43
Event of Default existed or exists, specifying the nature and period of
existence thereof and what action Lessee has taken or is taking or proposes to
take with respect thereto;

                  (vi) as soon as practicable after becoming aware thereof,
notice of damage or destruction to the Aircraft, either Engine or any Part with
a repair or replacement cost (including labor charges) in excess of $1,000,000;

                  (vii) immediately after Lessee knows or should know of the
occurrence thereof, notice of a Default; and

                  (viii) from time to time such other information as Lessor may
reasonably request.

            (b) Maintenance of Corporate Existence. Except as provided in
Section 8(e) below, during the term of this Lease, Lessee will preserve and
maintain its corporate existence and its rights, privileges, licenses and
franchises material to Lessee's ability to perform its obligations hereunder in
each applicable jurisdiction.

            (c) Maintenance of Status. Lessee is, and shall remain so long as it
shall be the Lessee under this Lease, a "citizen of the United States" as
defined in Section 40102(a)(15) of the Federal Aviation Act, and Lessee is and
shall maintain its status at all times as a Certificated Air Carrier, including,
without limitation, its status so as to fall within the purview of 11 U.S.C.
Section 1110 or any analogous statute.

            (d) Payment of Taxes. Lessee will pay or cause to be paid all Taxes
imposed upon it, or upon its income or profits, or upon any property belonging
to it, on or prior to the due date thereof, including any extensions which have
been duly obtained or granted; provided, however, that Lessee shall not be
required to pay any such Taxes, the payment of which is being diligently
contested in good faith and by appropriate proceedings with appropriate reserves
so long as there is no material possibility that either failure to pay such
Taxes or such contest may result in any loss, sale, confiscation, forfeiture or
seizure of the Aircraft, the Airframe or either Engine or any criminal liability
on the part of Lessor, Indenture Trustee or any Note Holder.

            (e) Consolidation, Merger, Etc. Lessee shall not liquidate or
dissolve; and Lessee shall not consolidate with


                                      -42-
   44
or merge into or with any other corporation or other Person, and Lessee shall
not convey, transfer, lease or otherwise dispose of all or substantially all of
its property and other assets (in one or a series of transactions) to any
corporation or other Person, unless:

                  (i) the Person formed by or surviving such consolidation or
merger or the Person which acquires by conveyance, transfer, lease or other
disposition all or substantially all of such property and other assets or stock
(the "Successor Entity"): (A) shall be a corporation organized and existing
under the Laws of the United States of America or any State thereof or the
District of Columbia; (B) immediately after giving effect to such transaction,
shall be Lessee or shall have acquired or succeeded to all or substantially all
of such property and other assets (including, without limitation, all or
substantially all of Lessee's property and other assets) as an entirety and,
unless the Owner Participant otherwise agrees, shall have a Net Worth of not
less than Lessee's Net Worth immediately prior to such transaction; (C) shall be
a "citizen of the United States" of America as defined in Section 40102(a)(15)
of the Federal Aviation Act and a Certificated Air Carrier; and (D) shall
execute and deliver to Lessor and Indenture Trustee such recordations and
filings with any Governmental Entity and such other documents as Lessor
determines shall be reasonably necessary or advisable (including, without
limitation, to preserve and protect the interests of the Lessor and the priority
of the Lien of the Indenture (if it has not been discharged)) to evidence, or in
connection with, such consolidation, merger, sale, lease, transfer or other
disposition and an agreement, in form and substance reasonably satisfactory to
Lessor, which is a legal, valid, binding and enforceable assumption by such
Successor Entity of the due and punctual performance and observance of each
covenant and condition of this Lease and the other Operative Documents to which
Lessee is a party and agreement to be bound thereby, and an officer's
certificate to such effect, and to the effect that the other requirements of
this paragraph have been satisfied, and a legal opinion from counsel to such
effect and otherwise in such form and substance reasonably satisfactory to
Lessor; and

                  (ii) prior to and immediately after giving effect to such
transaction, no Default or Event of Default shall have occurred and be
continuing.



                                      -43-
   45
No such permitted disposition to a Successor Entity shall relieve or release
Lessee of or from any obligations hereunder or under the other Operative
Documents.

            (f) Information. Within 60 days after the end of each calendar year
and within 60 days of a request by Lessor or Owner Participant, or such shorter
period as may be set forth in any written request by the Internal Revenue
Service for information or documents, Lessee shall furnish in writing to Lessor
or Owner Participant such information and documents (or copies thereof)
regarding the Aircraft as may be reasonably requested by Lessor or Owner
Participant or the Internal Revenue Service in order to permit Lessor to file
its Federal and state income tax returns (or to permit the filing of the Federal
and state income tax returns of any affiliated group of corporations filing a
consolidated return of which Lessor is a member), or to maintain or defend any
claims related thereto and promptly, after reasonable notice, furnish to Lessor
or Owner Participant such information as may be reasonably requested by Lessor
or Owner Participant or the applicable Governmental Entity as may be required to
enable Lessor or Owner Participant to file any reports required to be filed by
it with any Governmental Entity because of its ownership or other interest in
the Aircraft, the Airframe or the Engines.

            (g) Place of Business. At all times while this Lease is in effect,
Lessee will not, without thirty (30) days prior written notice to Lessor and
Indenture Trustee (so long as the Lien of the Indenture shall not have been
discharged), change its chief executive office (as such term is defined under
Article 9 of the Uniform Commercial Code as adopted in Arizona) or location of
its books and records, from 4000 East Sky Harbor Boulevard, Phoenix, Arizona
85034, or such subsequent location of which Lessee shall have so notified Lessor
and, if applicable, Indenture Trustee.

            (h) Certain Limitations on Use. Lessee shall use the Aircraft,
Airframe or Engines only in commercial passenger operations and related cargo
operations. Unless Owner Participant otherwise agrees, during the Restricted Use
Period, Lessee shall not use the Aircraft, Airframe or Engines or permit the
Aircraft, Airframe or Engines to be used either "predominantly outside the
United States" within the meaning of Section 48(a)(2) of the Code, or in such
manner that the percentage of the income, deduction or credit attributable to
the Aircraft, Airframe or Engines for federal income tax purposes during any
taxable year of the Lessor considered to be from foreign sources exceeds the


                                      -44-
   46
Maximum Foreign Use Percentage. Unless the Owner Participant otherwise agrees,
prior to permitting the Aircraft to be operated in any member state of the
European Union or other European country, Lessee shall deliver to Lessor (i) a
representation and warranty to the effect that Lessee (or any Permitted
Sublessee) has no knowledge of any dispute with Eurocontrol or other relevant
air traffic control authority over delinquent charges payable by it and (ii) a
letter from Lessee (or any Permitted Sublessee) addressed to Eurocontrol or
other relevant air traffic control authority pursuant to which Lessee (or such
Permitted Sublessee) authorizes the addressee to issue to Lessor, upon Lessor's
request from time to time, a statement of account of all sums due by Lessee (or
such Permitted Sublessee) to the authority in respect of all aircraft
(including, without limitation,the Aircraft) operated by Lessee (or such
Permitted Sublessee).

            (i) Section 1110. Lessee acknowledges that Lessor would not have
entered into this amended and restated Lease unless it had available to it the
benefits of a lessor under Section 1110 of Title 11 of the United States Code.
Lessee covenants and agrees with Lessor that to better ensure the availability
of such benefits, Lessee shall support any motion, petition or application filed
by Lessor with any bankruptcy court having jurisdiction over Lessee, whereby
Lessor seeks recovery of possession of the Aircraft under said Section 1110 and
shall not in any way oppose such action by Lessor unless Lessee shall have
complied with the requirements of said Section 1110 to be fulfilled in order to
entitle Lessee to continued use and possession of the Aircraft hereunder. The
acknowledgement, covenant and agreement contained in this Section 8(i) shall
continue in full force and effect and survive the expiration or other
termination of this Lease and are expressly made for the benefit of and shall be
enforceable by the Lessor, the Owner Participant and, if the Lien of the
Indenture has not been discharged, the Indenture Trustee.

            (j) Permits and Licenses. Lessee shall make or obtain, and maintain
in full force and effect, each and every consent, license, approval, notice,
registration, filing or other action with any Governmental Entity necessary or
advisable in connection with the operation or use of the Aircraft, the Airframe,
any Engine or Part or the execution, delivery or performance of this Lease or
the enforcement thereof against Lessee.

the Aircraft is registered under the Federal Aviation Act, Lessee shall furnish
to Lessor and to Indenture Trustee:

                  opinion of counsel rendered on the Restatement Date, any
                  opinion of counsel rendered pursuant to Section 11(C) of the
                  Refunding Agreement, and any opinion of counsel rendered
                  pursuant to this Section 8(k)(i) and (Y) upon any change in
                  Law that would render the opinion of counsel rendered on the
                  Restatement Date or such immediately preceding opinion of
                  counsel inaccurate, an opinion of counsel with respect to
                  Lessee and the FAA reasonably satisfactory to each addressee
                  of such opinion (which counsel may be internal legal counsel
                  of Lessee and FAA counsel) stating, in the opinion of such
                  counsel, that such action has been taken with respect to the
                  recording, filing, re-recording and refiling of (i) the
                  appropriate Operative Documents and any supplements and
                  amendments thereto and (ii) such other appropriate documents,
                  as is necessary to maintain the perfection of Lessor's title
                  to and/or interest in and Indenture Trustee's security
                  interest in the Aircraft and the Operative Documents for such
                  period of time as reflects the then-current applicable Law,
                  reciting the details of such actions; or

            (2)   at any time that an opinion is not required pursuant to
                  Section 8(k)(i)(1), annually, a certificate reasonably

                  Officer of Lessee certifying that no such action is necessary
                  to maintain the perfection of such title and/or interest and
                  security interest.

            (ii) During such times that the Aircraft is registered under any
Laws other than the Federal Aviation Act, Lessee shall furnish to Lessor and to
Indenture Trustee annually (but in any case, (X) prior to the expiration of the
time period covered by any opinion of counsel rendered pursuant to Section 11(C)
of the Refunding Agreement, and any opinion of counsel rendered pursuant to this
Section

immediately preceding opinion of counsel inaccurate), an opinion of counsel
reasonably satisfactory to each addressee of such opinion stating, in the
opinion of such counsel, that such action has been taken with respect to the
recording, filing, re-recording and refiling of (i) the appropriate Operative
Documents and any supplements and amendments thereto and (ii) such other
appropriate documents, as is necessary to maintain the perfection of Owner
Trustee's title to and/or interest in and Indenture Trustee's security interest
in the Aircraft and the Operative Documents for such period of time as reflects
the then-current applicable Law, reciting the details of such actions.

            (l) Letter of Credit. As security for the obligations to Lessor,
Lessee shall provide to Lessor, as named beneficiary thereof, one or more
irrevocable standby letters of credit, in form and substance acceptable to
Lessor in its sole and absolute discretion (the "Letter of Credit"), including,
without limitation, as to renewal provisions, with a face amount available for
drawdown at all times equal to the amount set forth on Exhibit C (the "Face
Amount"), which Letter of Credit shall:

                  (i) provide that the full amount thereof shall be available
for drawdown thereunder and payable in New York, New York, on demand at any
time, if a Default under Section 17(e), (f) or (g) or an Event of Default has
occurred, which amount may be applied, retained or utilized as provided in the
penultimate paragraph of this Section 8(l).

                  (ii) be maintained in full force and effect at all times until
ninety-one (91) days after the Expiration Date with a commercial bank acceptable
to Lessor, in its sole and absolute discretion, having a long-term unsecured
debt rating of "A" or better by Standard & Poor's Rating Group (if the issuing
bank's credit rating is lower than such rating, Lessee shall replace such Letter
of Credit issuer within five Business Days of any such reduction in rating with
a commercial bank meeting such rating requirement), provided, that a Letter of
Credit set forth in Exhibit D-2 issued by The Industrial Bank of Japan, Limited,
will be acceptable to Lessor for so long as The Industrial Bank of Japan,
Limited maintains a long term unsecured debt rating at least equal to its rating
on the date hereof;



                                      -47-
   49
                  (iii) be expressly designated as transferrable and assignable;
and

                  (iv) permit partial drawings. If the Letter of Credit is still
in effect at the end of the Term, or the Lessor is holding proceeds of the
Letter of Credit that were retained and not applied as provided herein then
Lessor shall return the Letter of Credit to Lessee or terminate it and/or return
any retained and unapplied proceeds, ninety-one (91) days following the date of
such expiration or other termination of this Lease so long as no Default or
Event of Default has occurred or is continuing hereunder or under any Other
Lease, upon payment in full of all amounts then due and owing to Owner Trustee
and Owner Participant under the Operative Documents.

            If an Event of Default has occurred or is continuing under this
Lease or an Event of Default has occurred or is continuing under any Other Lease
(as therein defined), in addition to any other rights and remedies Lessor may
have hereunder, under any Other Lease, any sublease and any and all other
remedies available at Law (including, without limitation, the Uniform Commercial
Code as adopted in New York) or equity and upon exercising its rights under the
Letter of Credit and any Other Letters of Credit, Lessor shall be entitled, in
each case as it may elect in its sole and absolute discretion, to (i) hold any
amounts drawn under the Letter of Credit or Other Letters of Credit as security
for Lessee's obligations under this Lease or the Other Leases, (ii) retain any
amounts drawn under the Letter of Credit or Other Letters of Credit for its own
account and apply (including, without limitation, by way of set off against)
such drawn amounts as it may elect (it being understood that amounts not so
applied will be held as security for Lessee's obligations under this Lease and
the Other Leases) to remedy any breach by Lessee of this Lease or any other
Operative Documents or Other Leases or (iii) recompense Lessor, Owner
Participant or any of their respective Affiliates for any loss, damage, cost or
expense or other Claim due or owing hereunder or under the Other Leases;
provided, however, that in the case of any drawing in respect of any claim for
the payment of Rent, Lessee's right to apply the same to such claim shall be
limited to amounts which would (absent such Event of Default) be distributable
under the Indenture at the time such payment is made to Lessor, Owner
Participant or any of their respective Affiliates (and shall not include any
amounts distributable to Indenture Trustee in its individual capacity or to the
Note Holders); provided further, however, that neither the amount so applied at
any one time nor the aggregate amount so applied at different times shall reduce
the amount of any installment or payment of Rent (whether


                                      -48-
   50
upon the termination of the Lease or otherwise) payable by Lessee to an amount
insufficient to pay in full the amounts required to be paid on account of the
principal of and any interest on the Equipment Notes or otherwise owing to a
Note Holder. Lessee shall not be entitled to any refund or credit with respect
to any amounts so applied. Any amount retained shall be considered the property
of Lessor and Lessor may commingle such amount with its general funds and
Lessee, further, hereby absolutely and irrevocably disclaims, to the maximum
extent permitted by applicable Law, any interest therein. Lessee shall not be
entitled to any interest or other earnings on such retained amount and such
amount shall not be refundable.

            On application of all or any portion of the amounts drawn under the
Letter of Credit or any Other Letters of Credit in accordance with this Section
8(l), or the Other Leases, Lessee shall on demand reinstate the amount of the
Letter of Credit or Other Letters of Credit, as the case may be, to its or their
full Face Amount or provide to Lessor one or more additional Letters of Credit
meeting the requirements of this Section 8(l), so that the Letter of Credit and
each of the Other Letters of Credit at all times equals the original Face Amount
provided for herein. During such times as Lessor shall elect to hold all or part
of the proceeds of the Letter of Credit or Other Letters of Credit as security
for Lessee's obligations to Lessor under the Lease and the Other Leases, Lessee
shall not be obligated to reinstate the amount of the Letter of Credit or
Letters of Credit, as the case may be, in respect of the proceeds so held.

            Section 9. Replacement of Parts; Alterations, Modifications and
Additions.

            (a) Replacement of Parts. Lessee, at its own cost and expense, will
promptly replace, or cause to be replaced, all Parts which 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 (or, if a Permitted Sublease is in effect, a Permitted
Sublessee) may at its own cost and expense 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 (or, if a Permitted
Sublease is in effect, a Permitted Sublessee) shall replace at its own cost and
expense such Parts as promptly as


                                      -49-
   51
possible. All replacement Parts shall be free and clear of all Liens (except for
pooling arrangements to the extent permitted by paragraph (c) of this Section
and Permitted Liens), be in at least the equivalent or better modification
status and service bulletin accomplishment status, be fully interchangeable as
to form, fit and function and shall be in as good operating condition as, and
have a value, remaining useful life and utility at least equal to, the Parts
replaced (assuming such replaced parts were in the condition and repair in which
they were required to be maintained by the terms hereof).

            All Parts which are at any time removed from the Aircraft shall
remain the property of Lessor, subject to the Lien of the Indenture if it has
not been discharged, and subject to this Lease no matter where located until
such time as such Parts shall be replaced by parts which have been incorporated
or installed in or attached to the Aircraft and which meet the requirements for
replacement Parts specified above. Immediately upon any replacement Part
becoming incorporated or installed in or attached to the Aircraft as above
provided, or as provided in Section 9(c), without further act, (i) title to the
removed Part shall thereupon vest in Lessee free and clear of all rights of
Lessor, Indenture Trustee, Owner Participant and Note Holders and shall no
longer be deemed a Part hereunder, (ii) title to such replacement Part shall
thereupon vest in Lessor and become subject to the Lien of the Indenture if it
has not been discharged, and (iii) such replacement Part shall become subject to
the Lien of the Indenture (if it has not been discharged) and this Lease and be
deemed a Part for all purposes hereof to the same extent as the Part which it
has replaced.

            (b) Alterations, Modifications and Additions. Lessee, at its own
cost and expense, shall make or cause to be made such alterations and
modifications in and additions to the Airframe and each Engine to the extent
made mandatory for Lessee (or a sublessee) in respect of the Aircraft, Engines
or Parts from time to time to meet the applicable standards of the FAA or under
any Law of any Governmental Entity having jurisdiction or issued by the
manufacturer of the Airframe, Engines or Parts. In addition, so long as no
Default or Event of Default has occurred and is continuing, Lessee (or, if a
Permitted Sublease is in effect, a Permitted Sublessee), at its own expense, may
from time to time make such alterations and modifications in and additions to
the Airframe and either Engine as Lessee (or, if a Permitted Sublease is in
effect, a Permitted Sublessee)


                                      -50-
   52
may deem desirable in the proper conduct of its business, provided, no such
alteration, modification or addition diminishes the value, remaining useful life
or utility, or impairs the condition or airworthiness, of the Airframe, either
Engine or any Part below that immediately prior to such alteration, modification
or addition assuming that the Airframe, Engines and Parts were then of the
value, utility and remaining useful life and in the condition and airworthiness
required by the terms of this Lease. Except as otherwise provided herein, title
to all Parts incorporated or installed in or attached or added to the Aircraft
as the result of such alteration, modification or addition, shall immediately
vest in Lessor and become subject to the Lien of the Indenture (if it has not
been discharged) and this Lease, without the necessity for any further act of
transfer, document or notice. Notwithstanding the foregoing sentence of this
Section 9(b), Lessor agrees that so long as no Default or Event of Default shall
have occurred and be continuing Lessee (or, if a Permitted Sublease is in
effect, a Permitted Sublessee) may, at such time during the Term for the
Aircraft, remove any Part of such Aircraft, 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, or delivered with, the Aircraft on
the Delivery Date or any Part in replacement of, or substitution for, any such
originally incorporated, installed, attached or delivered 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 Section 6 or this Section 9 or to maintain the
insurance required by Section 12 and (iii) such Part can be removed from the
Aircraft without causing any material damage thereto and without diminishing or
impairing the value, utility, remaining useful life, 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 (or, if a Permitted Sublease is in effect, a Permitted Sublessee)
and such Part shall no longer be deemed part of the Aircraft (such a part is
herein called a "Removable Part"). Any Part not removed by Lessee as above
provided prior to the return of the Aircraft to Lessor hereunder, whether
pursuant to Section 16, Section 18 or otherwise, shall remain the property of
Lessor.

            If any Removable Part is (i) owned by any third party and leased to
Lessee (or, if a Permitted Sublease is in effect, a Permitted Sublessee), (ii)
sold to Lessee (or,


                                      -51-
   53
if a Permitted Sublease is in effect, a Permitted Sublessee) subject to a
conditional sale contract or other security interest or (iii) leased to Lessee
(or, if a Permitted Sublease is in effect, a Permitted Sublessee) 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 on the Aircraft; provided,
however, that (A) Lessor's inability to so acquire or claim is subject to the
express condition that such lessor, conditional vendor, or secured party shall
have agreed in writing (which agreement may be contained in the lease,
conditional sale agreement or security agreement) not to 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 (B) any Removable Part not removed by Lessee upon the
termination or expiration of this Lease, at such time, shall become the property
of Lessor and be subject to this Lease, and provided, further, that (1) if
removal of any such Part shall affect the operation of the Aircraft in any way
whatsoever, Lessee shall replace such Part with an owned Part of the same value,
utility and remaining useful life and (2) Lessee shall repair any unsightly area
of the Aircraft as a result of such removal and make all other repairs which are
advisable and result from such removal.

            In the event Lessee (or, if a Permitted Sublease is in effect, a
Permitted Sublessee) replaces a Part which is not required to be replaced under
Section 9(a) or 9(b) hereof, Lessee (or, if a Permitted Sublease is in effect, a
Permitted Sublessee) may remove the replacement Part so long as it reinstalls
the original Part and such original Part is free and clear of all Liens, other
than Permitted Liens, is in at least the same modification status and service
bulletin accomplishment status, is fully interchangeable as to form, fit and
function, has been overhauled, repaired and inspected by an agency acceptable to
the FAA or other Governmental Entity having jurisdiction, and is in as good
operating condition as, and has a utility, remaining useful life and a value at
least equal to that of such Part when it was removed from the Aircraft.

            Notwithstanding any other provision hereof, and without limiting the
foregoing, Lessee (or, if a Permitted Sublease is in effect, Permitted
Sublessee) may install in the Aircraft audio visual, entertainment or telephonic


                                      -52-
   54
equipment (including seats with such equipment installed therein) (any or all of
which are hereafter referred to as "Excluded Property") in the ordinary course
of business, and Lessor shall not claim or acquire title thereto and the rights
of the owners thereof therein shall not constitute a default hereunder; provided
that (i) any such Excluded Property shall be removed prior to the date of a
Return Occasion without causing any damage to the Aircraft and without
diminishing or impairing the value, utility, remaining useful life or condition
which the Aircraft would have had at such time had such Excluded Property not
been installed, (ii) any equipment or seats which such Excluded Property
replaces shall be properly stored with the interests of Lessor and, if the Lien
of the Indenture is in effect, the Indenture Trustee, duly noted thereon and
acknowledged by any applicable bailee or warehouse, and properly reinstalled on
the Aircraft prior to the date of a Return Occasion, and (iii) Lessee (or such
Permitted Sublessee) shall make all repairs which are required as a result of
such removal and/or reinstallation.

            In no event shall Lessor bear any liability or cost for any
alteration, modification, or addition, or for any grounding or suspension of
certification of the Aircraft, or for any loss of revenue arising therefrom.

            (c) Pooling. Any Part removed from the Airframe or either Engine as
provided in Section 9(a) may so long as no Default or Event of Default shall
have occurred and be continuing or would result therefrom be subjected by Lessee
(or, if a Permitted Sublease is in effect, a Permitted Sublessee) to a normal
pooling arrangement customary in the airline industry of which Lessee (or, if a
Permitted Sublease is in effect, a Permitted Sublessee) is a part entered into
in the ordinary course of Lessee's or such Permitted Sublessee's business,
provided the Part replacing such removed Part shall be incorporated or installed
in or attached to the Aircraft in accordance with Section 9(a) as promptly as
possible, and in any event within sixty (60) days, after the removal of such
removed Part. In addition, any Replacement Part when incorporated or installed
in or attached to the Airframe or any Engine in accordance with Section 9(a) may
be owned by another Person subject to such a normal pooling agreement; provided,
however, that Lessee (or, if a Permitted Sublease is in effect, a Permitted
Sublessee), at its own expense, as promptly thereafter as possible, and in any
event within sixty (60) days, either (i) causes title to such replacement Part
to vest with Lessor in accordance with Section 9(a) (and to be subjected


                                      -53-
   55
to the Lien of the Indenture if it has not been discharged) by Lessee (or, if a
Permitted Sublease is in effect, a Permitted Sublessee) acquiring title thereto
for the benefit of and transferring title to Lessor free and clear of all Liens
except Permitted Liens, whereupon such replacement Part shall become subject to
this Lease and the Lien of the Indenture (if in effect) without the necessity
for any further act, document or notice, or (ii) replaces such replacement Part
by incorporating or installing in or attaching to the Aircraft a further
replacement Part owned by Lessee (or, if a Permitted Sublease is in effect, a
Permitted Sublessee) free and clear of all Liens other than Permitted Liens and
by causing title to such further replacement Part to vest in Lessor as above
provided and to be subjected to the Lien of the Indenture if it has not been
discharged, whereupon such replacement Part shall become subject to this Lease
and the Lien of the Indenture (if in effect) without the necessity for any
further act, document or notice.

            Section 10. General Tax Indemnity.

            (a) Indemnity. Lessee agrees that each payment of Basic Rent
hereunder shall be free and clear of, and without deduction for, any and all
withholdings on account of Taxes of any nature whatsoever, whether or not an
exclusion pursuant to Section 10(b) applies, except as required by law. If any
such deduction or withholding of Taxes is required with respect to such payments
of Basic Rent, Lessee shall pay an additional amount of Basic Rent such that the
net amount actually received by Lessor, after such deduction or withholding,
will be equal to all such amounts that would be received by Lessor if no such
deduction or withholding had been required, but only to the extent necessary to
ensure that the holders of the outstanding Equipment Notes receive such amount
as may be required by the Indenture. If Lessee pays any amount to Lessor (or to
any taxing authority for the account of Lessor) as a result of the application
of the preceding sentence with respect to any withholding Tax which is an
excluded tax in respect of Lessor pursuant to Section 10(b), then Lessor (or, in
the case of Taxes imposed on the Owner Trustee, the Owner Participant to the
extent such Tax would give rise to a Lessor's Lien for which the Owner
Participant would be liable) shall reimburse Lessee for such withholding Tax
within 30 days of written notice accompanied by evidence of payment for such
withholding Taxes (exclusive of interest, penalties and additions to Tax) paid
by Lessee provided that in any circumstance in which the Lessor is


                                      -54-
   56
required to reimburse the Lessee for any such withholding Taxes and the Lessee
has not received such reimbursement from Lessor or the Owner Participant, then
to the extent of such shortfall and so long as no Lease Event of Default has
occurred and is continuing, Lessee shall be entitled to obtain reimbursement
from Lessor by reducing the succeeding payments of Rent payable to Lessor (other
than any portion of Rent that may be required by the Indenture to be paid to the
holders of any outstanding Equipment Notes issued thereunder) until the
aggregate amount of reduction is equal to the sum of the amount of such
shortfall and interest on that amount at the Interest Rate from the date
reimbursement is required to be made until the date of such reduction in Rent.
Except as provided in Section 10(b), and taking into account any payments
received by Lessor pursuant to the second sentence of this Section 10(a), Lessee
agrees to pay, and to indemnify and hold each Indemnitee harmless from, any and
all Taxes, howsoever levied or imposed, whether levied or imposed upon or with
respect to or asserted against any Indemnitee, Lessee, the Aircraft, the
Airframe, any Engine or any Part thereof or interest therein, or otherwise, with
respect to any period beginning, or events or circumstances occurring, on or
after the Restatement Date, by any federal, state or local government or taxing
authority in the United States of America or by any foreign government or any
taxing authority or governmental subdivision of a foreign country or of a
territory or possession of the United States (each such governmental subdivision
or taxing authority referred to as a Taxing Authority"):

                  (i) upon or with respect to, based upon or measured by (A) the
         Aircraft, the Airframe, any Engine or any Part thereof, or interest
         therein, (B) the manufacture, purchase, ownership, delivery, leasing,
         acceptance, rejection, assigning, possession, use, operation, location,
         settlement of any insurance claim, sale, mortgaging, pledging,
         financing, subleasing, rental, retirement, abandonment, registration,
         re-registration, deregistration, preparation, installation,
         modification, repair, maintenance, replacement, transportation,
         storage, transfer of title, return or other disposition of the
         Aircraft, the Airframe, any Engine or any Part thereof or interest
         therein; or (C) the rentals, receipts, income or earnings arising
         therefrom (including without limitation the Rent), or

                  (ii) upon or with respect to the Operative Documents
         (including the Equipment Notes), any interest


                                      -55-
   57
         in any thereof, or any future amendment, supplement, waiver or consent
         thereto requested by Lessee with respect to any thereof, or the
         execution, delivery, or performance of any thereof, or the acquisition
         or subsequent transfer thereof or the issuance of the Equipment Notes
         or any other document executed and delivered in connection with the
         consummation or confirmation of the transactions contemplated by the
         Operative Documents or any Indemnitee's interest in any of the
         foregoing, or the execution, amendment, supplement, issuance,
         reissuance, refinancing or delivery of any of the foregoing, or

                  (iii) the Trust Indenture Estate or the property, or the
         income or other proceeds received with respect to the property, held by
         the Indenture Trustee under the Indenture, or

                  (iv) the payment of the principal of, or interest or premium
         on, or other amounts payable with respect to the Equipment Notes,
         whether as originally issued or pursuant to any modification or
         reissuance, or

                  (v) otherwise with respect to or in connection with the
         transactions contemplated by the Operative Documents.

            (b) Exclusions. The following Taxes shall not be subject to
indemnification under subsection (a) of this Section 10:

                  (i) In the case of any Indemnitee, Taxes imposed on, based on,
         or measured by, the gross or net income of such Indemnitee or Taxes in
         lieu thereof (including minimum taxes, withholding taxes and taxes on
         or measured by any item of tax preference) imposed by the federal
         government of the United States of America (other than taxes in the
         nature of sales or use taxes, license taxes, or property taxes),

                  (ii) In the case of any Indemnitee, Taxes imposed on, based
         on, or measured by the gross or net income, receipts, capital, or net
         worth, franchises, excess profits or conduct of business of such
         Indemnitee (including minimum taxes, withholding taxes and taxes on or
         measured by any items of tax preference), imposed by any state, local
         or foreign government or taxing authority (other than Taxes in the


                                      -56-
   58
         nature of sales Taxes, use Taxes, license Taxes or property Taxes, and
         Covered Income Taxes described in subsection (c) of this Section 10),

                  (iii) In the case of any Indemnitee, Taxes which arise out of
         or are caused by any gross negligence or willful misconduct of such
         Indemnitee,

                  (iv) In the case of any Indemnitee, any Taxes imposed as a
         result of a voluntary or involuntary bankruptcy of such Indemnitee or
         any sale, transfer of title, transfer or other disposition by such
         Indemnitee or a related Indemnitee (for such purpose, Owner Trustee and
         Owner Participant are related Indemnitees with respect to each other)
         of the Aircraft, the Airframe, any Engine or any Part thereof or
         interest therein, or any interest in the Rent or part thereof or any
         interest in the Operative Documents or part thereof, unless such sale,
         transfer or disposition occurs in connection with (A) an Event of
         Default and the exercise by any Indemnitee of its remedies under this
         Lease or the Indenture, as the case may be or (B) the substitution,
         pooling or interchange of the Aircraft, the Airframe, any Engine or any
         Part pursuant to the terms hereof; provided, however, that in all cases
         Owner Participant and Owner Trustee shall consider in good faith such
         request as Lessee shall make concerning the appropriate jurisdiction in
         which such sale, transfer or disposition shall be made,

                  (v) In the case of any Indemnitee, Taxes imposed on a
         transferee of such Indemnitee of any interest in the Aircraft, the
         Airframe, any Engine or any Part or any interest in the Operative
         Documents to the extent the amount of any such Taxes exceeds the amount
         of such Taxes that would have been imposed had there not been any such
         transfer, unless such transfer results from action by or on behalf of
         such Indemnitee taken in connection with any Event of Default that has
         occurred and is continuing or upon the request of the Lessee,

                  (vi) Any interest, penalties, fines and additions to tax
         imposed on an Indemnitee (other than Taxes that are due and payable
         with a return when properly filed) resulting from such Indemnitee's
         failure to file returns that are timely and proper, provided such
         failure was not attributable to such Indemnitee contesting any claim in
         accordance with this


                                      -57-
   59
         Section 10(b) or to a failure by Lessee to satisfy its obligations
         related to such return,

                  (vii) With respect to an Indemnitee other than the Indenture
         Trustee or the Trust Indenture Estate, Taxes which arise out of or are
         caused by (i) any act or omission or material misrepresentation of any
         Indemnitee where such act or omission is not permitted by the Financing
         Documents or the Operative Documents, or (ii) a failure by an
         Indemnitee to fulfill its contest obligations, and, in the case of the
         Indenture Trustee and the Trust Indenture Estate, Taxes imposed as a
         result of a breach of such Indemnitee's representations, warranties, or
         covenants contained in Sections 9(a), 12 or 16 of the Refunding
         Agreement in any material respect, or from a failure by such Indemnitee
         to fulfill its contest obligations,

                  (viii) So long as no Event of Default shall have occurred and
         be continuing, Taxes attributable to the Aircraft related to acts or
         events occurring after the later of the termination of the Lease and
         the redelivery of the Aircraft,

                  (ix) In the case of each Pass-Through Trust, each Pass-Through
Trustee (in its individual capacity and as trustee under the Pass-Through
Trusts), the Subordination Agent and each Liquidity Provider, United States
withholding taxes imposed as a result of the place of organization or other
status of a holder of an interest in a Pass-Through Trust, or

                  (x) In the case of the Indenture Trustee, each Pass-Through
Trust, each Pass-Through Trustee (in its individual capacity), the Subordination
Agent and each Liquidity Provider, Taxes imposed with respect to the Equipment
Notes as a result of activities of such Indemnitee unrelated to the transactions
contemplated by the Operative Documents.

            (c) Covered Income Tax. For purposes of clause (ii) of subsection
(b) of this Section 10, a Covered Income Tax includes:

                  (i) in the case of an Indemnitee other than the Indenture
         Trustee or the Trust Indenture Estate, any Tax imposed on, based on or
         measured by gross or net income, receipts, capital or net worth,
         franchises, excess profits or conduct of business (other than taxes
         which are in the nature of sales or use taxes, license taxes or
         property taxes) imposed on an Indemnitee (A)


                                      -58-
   60
by any state or local Taxing Authority other than Taxes imposed by any such
state or local jurisdiction in which the Indemnitee has its principal place of
business or is subject to such Tax as a result of business transactions or other
presence unrelated to the transactions contemplated by the Financing Documents
or the Operative Documents, unless such Taxes are imposed by such jurisdiction
solely as a result of (x) the operation of the Aircraft in such jurisdiction or
(y) the transactions contemplated by the Operative Documents, to the extent such
taxes are directly attributable to such operation of the Aircraft or to such
transactions, and (B) by any foreign jurisdiction which are imposed as a result
of Lessee's or sublessee's activities in such foreign jurisdiction in connection
with the transactions contemplated by the Financing Documents or the Operative
Documents, provided, however, a Covered Income Tax also includes the incremental
amount of franchise taxes, taxes on doing business, capital stock taxes or taxes
on, based on or measured by gross or net income of the original Owner
Participant attributable to the Lease (excluding, however, any taxes that would
be excluded under any provision other than clauses (i) and (ii) of subsection
(b) of this Section 10) which are imposed by the "Home State" of a sublessee
(the Home State of a sublessee being the jurisdiction in which such sublessee
maintains its principal operations and maintenance center), or in the absence of
a Permitted Sublessee, the jurisdiction where the Aircraft is stored, but only
to the extent such incremental taxes result from activities of Lessee or
Permitted Sublessee under the Lease in or with respect to the Home State or the
jurisdiction where the Aircraft is stored, and taking into account in
calculating such incremental taxes all state tax benefits and savings in the
Home State resulting from activities of Lessee or Permitted Sublessee under the
Lease, disregarding for such purpose any actual or constructive changes in
ownership of the original Owner Participant, provided, however, that Owner
Participant and Lessee agree to negotiate, in good faith, a cap to Lessee's
liability for indemnity payments attributable to taxes incurred in sublessee's
Home State with respect to each Permitted Sublessee; and

                  (ii) in the case of the Indenture Trustee or the Trust
         Indenture Estate, any Tax based on or measured by gross or net income,
         receipts, capital or


                                      -59-
   61
         net worth, franchises, excess profits or conduct of business (including
         minimum taxes, withholding taxes, and taxes on or measured by any item
         of tax preference) imposed on such Indemnitee by a Taxing Authority in
         or of any foreign jurisdiction or a territory or possession of the
         United States, other than any such Tax which would not have been
         imposed in the absence of such Indemnitee's (including for purposes of
         this definition, all entities with which such Indemnitee is combined,
         integrated, or consolidated in such Taxing Authority's jurisdiction)
         engaging in business, maintaining an office or other place of business
         or otherwise being located in such jurisdiction other than merely by
         reason of such Indemnitee's participation in the transactions
         contemplated by the Operative Documents.

            (d) Reports and Returns. In case any report or return is required to
be made by Lessee with respect to any Taxes which are subject to indemnification
by Lessee under this Section 10, Lessee will either make such report or return
in such manner as will show the ownership of the Aircraft in Owner Trustee or
the interest of Owner Participant or its permitted assigns and send a copy of
such report or return to the Owner Participant or Owner Trustee or will notify
the Owner Participant or Owner Trustee of such requirement and make such report
or return in such manner as shall be reasonably satisfactory to Owner
Participant or Owner Trustee. If actual notice is given by any taxing authority
to an Indemnitee that a report or return is required to be filed with respect to
any such Taxes, the Indemnitee shall promptly notify Lessee of such required
report or return and Lessee shall either file such report or return in the
manner prescribed in the preceding sentence, or shall use its best efforts to
cause such report or return to be filed by the appropriate entity. Each
Indemnitee agrees to respond to any reasonable request of Lessee for information
not within Lessee's control and within the control of and reasonably available
to such Indemnitee with respect to the filing of any such report or return, but
Lessee agrees to pay any reasonable costs, fees, disbursements or other charges
of independent counsel or independent accountants incurred in connection with
such request.

            (e) After-Tax Basis. Lessee further agrees that, with respect to any
payment or indemnity under this Section 10 and under Section 13 hereof, such
payment or indemnity shall include the net amount necessary to hold the
recipient


                                      -60-
   62
of the payment or indemnity harmless on an after-tax basis from all Taxes
required to be paid or credited by such recipient with respect to such payment
or indemnity under the laws of any Taxing Authority; provided, however, that in
the case of Taxes imposed on the Owner Participant, such Taxes shall be
calculated on the basis of the assumption that Owner Participant shall be
subject to the highest federal corporate income tax rate applicable to Owner
Participant in the year of payment and the highest corporate income tax rate in
the jurisdiction in which Owner Participant files a consolidated state income
tax return (currently Virginia).

            (f) Tax Benefit. If, by reason of any payment made to or for the
account of an Indemnitee by Lessee pursuant to this Section 10 or Section 13
hereof, such Indemnitee subsequently actually realizes a tax deduction or credit
(including foreign tax credit and any reduction in Taxes) not previously taken
into account in computing the amount of such payment, such Indemnitee shall
promptly pay to Lessee, but only if there shall then be no Lease Event of
Default and if Lessee shall have made all payments then due and owing to such
Indemnitee under the Operative Documents, an amount equal to the sum of (i) the
actual reduction in Taxes, if any, realized by such Indemnitee which is
attributable to such deduction or credit and (ii) the reduction calculated on
the same basis as the gross up in Section 10(e) hereof in Taxes realized by such
Indemnitee as a result of any payment made by such Indemnitee pursuant to this
sentence; provided, however, that such Indemnitee shall not be obligated to make
any payment pursuant to this Section 10 or Section 13 hereof to the extent that
the amount calculated pursuant to (i) above would exceed (A) the amount of all
prior payments by Lessee to such Indemnitee, pursuant to this Section 10 or
Section 13 hereof, net of any amount paid in respect of Taxes required to be
paid by such Indemnitee in respect of the receipt or accrual of such amounts
received by such Indemnitee from Lessee, less (B) the portion of all prior
payments computed pursuant to (i) above by such Indemnitee to Lessee hereunder.

            (g) Payment. If a claim is made against any Indemnitee for any Taxes
which may be subject to indemnification by Lessee hereunder and if such
Indemnitee has notice thereof, such Indemnitee shall promptly notify Lessee;
provided that the failure to provide such notice shall not release Lessee from
any of its obligations hereunder except to the extent Lessee's right to contest
such claim is precluded thereby. Any amount payable as an


                                      -61-
   63
indemnity to any Indemnitee or any amount payable to Lessee pursuant to this
Section 10 is to be paid to such party directly, in immediately available funds,
within thirty (30) days after receipt of a written demand therefor from such
Indemnitee or Lessee, as the case may be, except in the case of a payment to an
Indemnitee to the extent that such Taxes are being contested in good faith
pursuant to this Section 10, in which event the payment of such indemnity shall
be made by the due date for the payment of any Taxes that are the subject of
such contest taking into account all extensions of the due date that are
available as a result of the contest. In the event an Indemnitee makes a tax
payment with respect to any such Taxes (other than with funds advanced to such
Indemnitee on an interest-free basis by Lessee pursuant to this Section 10),
Lessee shall reimburse the amount of such payment and also shall pay to the
Indemnitee interest on the amount of such payment by such Indemnitee at the
Interest Rate from the date of any such payment by such Indemnitee to the date
of such reimbursement by Lessee to the Indemnitee hereunder. In the event an
amount is payable to Lessee under this Section 10, the Indemnitee owing such
amount shall pay interest on such amount at the Interest Rate from the date of
receipt by such Indemnitee of any amount giving rise to such obligation to pay
Lessee until the date of payment to Lessee.

            (h) Contest. In the event that an Indemnitee receives a written
notice of a claim which, if sustained, would require the payment of an indemnity
by Lessee pursuant to this Section 10, such Indemnitee shall promptly notify
Lessee of such claim and, if requested by Lessee in writing, shall, at Lessee's
sole expense, in good faith contest or shall permit Lessee, if desired by Lessee
and such contest may be conducted in whole or in part separately in the name of
Lessee without involving Taxes of such Indemnitee not indemnified hereunder, to
contest in the name of Lessee and/or the Indemnitee, the validity, applicability
or amount of such Taxes by (x) resisting payment thereof if practicable, (y) not
paying the same except under protest, if protest is necessary and proper, and
(z) if payments be made, using reasonable efforts to obtain a refund thereof in
appropriate administrative and judicial proceedings; provided, however, the
Lessee shall not be permitted to contest in the name of such Indemnitee if such
contest involves Taxes imposed against such Indemnitee that are unrelated to the
transactions contemplated by the Financing Documents or the Operative Documents
or Taxes based on or measured by the gross or net income of the Indemnitee, and
provided, that if the Indemnitee determines in good faith


                                      -62-
   64
that there is a material possibility of a material adverse impact upon the
Indemnitee with respect to such contest, such Indemnitee may retain or reassert
control of any contest that Lessee would otherwise be permitted to contest;
provided, further, that the Indemnitee shall not be required to undertake or
allow in its name or on its behalf any contest unless the following conditions
are satisfied:

                  (i) Lessee shall have (a) furnished Indemnitee with a written
         opinion of tax counsel selected by Indemnitee and reasonably acceptable
         to Lessee to the effect that a reasonable basis (as defined in ABA
         Opinion 85-352) exists to contest such claim (which opinion shall be
         obtained at Lessee's sole cost and expense), provided however, that in
         the event the subject matter of the contest is of a continuing nature
         and has previously been decided adversely pursuant to the contest
         provisions of this Section 10, there has been a change in the law
         (including, without limitation, amendments to statutes or regulations,
         administrative rulings and court decisions) after such claim shall have
         been so previously decided and such Indemnitee shall have received an
         opinion of tax counsel, to the effect that, as a result of such change
         other than a change in statutory law, it is more likely than not that
         the position which the Indemnitee or the Lessee, as the case may be,
         had asserted in such previous contest would prevail and, in the case of
         statutory changes-in-law, it is as likely as not that the position will
         prevail, and (b) agreed to pay Indemnitee for all reasonable costs and
         expenses which Indemnitee may incur in contesting such claim (including
         without limitation, payment on demand of all out-of-pocket costs,
         expenses, additions to tax because of underpayment of estimated taxes,
         losses, legal and accounting and investigatory fees and disbursements,
         penalties, and interests),

                  (ii) a threshold amount of $50,000 for any individual claim is
         at issue,

                  (iii) there is no substantial risk or danger of the sale, loss
         or forfeiture of the Aircraft,

                  (iv) Lessee shall have admitted its liability to indemnify
         Owner Participant for such claim or set forth in writing why it is not
         so liable,



                                      -63-
   65
                  (v) if such contest is to be initiated by the payment of, and
         the claiming of a refund for, such Taxes, the Lessee shall have
         advanced to such Indemnitee sufficient funds (on an interest free
         basis) to make such payments,

                  (vi) no claim shall be appealed to the U.S. Supreme Court,

                  (vii) no appeal of a trial court decision shall be undertaken
         unless Lessee at its sole cost and expense shall have furnished
         Indemnitee with a written opinion of tax counsel selected by Indemnitee
         and reasonably acceptable to Lessee to the effect that Indemnitee is
         more likely than not to prevail in such appeal, and

                  (viii) no Event of Default has occurred and is continuing.

            (i) Refund. If any Indemnitee shall obtain a refund of all or any
part of any Taxes paid by Lessee or from an advance by Lessee, such Indemnitee
shall pay Lessee the amount of such refund together with any interest paid
thereon attributable to the Taxes paid or advanced by Lessee less the amount of
any Taxes payable by such Indemnitee in respect of the receipt of such refund
and interest after giving credit to Lessee for any savings by such Indemnitee in
respect to any such Taxes by reason of deductions, credits, allocations or
allowances in respect of the payment of any such Taxes; provided that such
amount shall not be payable before such time as Lessee shall have made all
payments or indemnities then due to the Lessor and the Indemnitee under the
Lease and all other Operative Documents, and provided further that no amount
shall be payable during any period in which an Event of Default under the Lease
has occurred and is continuing unremedied unless this Lease has terminated and
Lessee has paid all amounts due the Lessor thereunder.

            (j) Diligence. Lessee shall not be deemed to be in default under any
of the above indemnification provisions of this Section 10 so long as Lessee or
the Indemnitee shall diligently prosecute such contest in accordance with the
provisions of this Section 10. Notwithstanding the foregoing, if a claim is made
against any Indemnitee for any Taxes which, if successful, would result in the
imposition of Taxes under circumstances which would require Lessee to indemnify
such Indemnitee, the Indemnitee shall be released


                                      -64-
   66
from its responsibility to contest such claim or part thereof, if it agrees in
writing not to seek indemnification from Lessee in respect of the claim, or such
part thereof to be contested. In the event an Indemnitee fails to contest, or
refuses to permit Lessee to contest, a claim or part thereof which the
Indemnitee has the obligation to contest or to permit Lessee to contest under
this Section 10, then Lessee shall not be obligated to indemnify the Indemnitee
for such claim or such part thereof.

            (k) Affiliated Group. In the event that the Indemnitee is a member
of an affiliated group (within the meaning of Section 1504(a) of the Code) which
files a consolidated Federal income tax return, the term "Indemnitee" shall mean
and include any member of such affiliated group.

            (l) Verification. At Lessee's request, the amount of any indemnity
payment by Lessee pursuant to this Section 10 or any payment by an Indemnitee to
Lessee pursuant to this Section 10 shall be verified and certified by an
independent public accounting firm selected by such Indemnitee and reasonably
satisfactory to Lessee. In order to enable such accountants to verify the
indemnity amount, such Indemnitee shall provide to the accountants (for their
own confidential use) information reasonably necessary for such verification to
which Lessor has access; provided, however, such information shall not be
disclosed to Lessee or any person other than such accountants. The fee of such
firm shall be payable by Lessee unless such verification shall result in an
adjustment in Lessee's favor exceeding 10% of the amount of the indemnity
payment.

            (m) Survival. All of the obligations and rights of Lessee and Lessor
under this Section 10 with respect to the Aircraft, the Airframe, the Engines or
any Part thereof shall survive the assignment, or expiration or other
termination, of the Lease with respect to the Aircraft for a period of six (6)
years from the occurrence of such assignment, or expiration or termination,
except that such obligations shall survive the expiration of such six (6) year
period with respect to any claim asserted prior to the expiration of such six
(6) year period but in either case only to the extent such obligation or claim
relates to events which occurred or conditions which existed during the Term.
Such obligations are expressly undertaken by Lessee for the benefit of, and
shall be enforceable by, Lessor. The provisions of this Section 10(m) are
subject to the exclusions of Section 10(b)(viii).


                                      -65-
   67
            Section 11. Loss, Damage and Requisition.

            (a) Event of Loss with Respect to the Airframe. Subject to the other
provisions of this Section 11, upon an Event of Loss with respect to the
Airframe or the Airframe and any Engines then installed thereon, Lessee shall
forthwith (and, in any event, within five (5) Business Days after such
occurrence) give Lessor written notice of such occurrence and within thirty (30)
days after such occurrence give Lessor written notice of its election, subject
to the terms hereof and of the Indenture, to perform one of the following two
options (it being agreed that if Lessee shall not have given Lessor notice of
such election within thirty (30) days after such occurrence, Lessee shall be
deemed to have elected to perform the option set forth in the following clause
(ii)), provided, that Lessee shall not have the right to select the option set
forth in clause (i) if a Default or an Event of Default shall have occurred and
be continuing at the time of such election or at the time of replacement:

                  (i) within one hundred twenty (120) days (the "Replacement
Period") after the date of the Event of Loss (but in no event later than the
last day of the Term) Lessee shall convey, or cause to be conveyed to Lessor as
provided in Section 11(c) hereof, to be subjected to the Lien of the Indenture
if it has not been discharged, and to be leased by Lessee hereunder in
replacement of the Airframe and such Engines then installed thereon, title to a
replacement Airframe (together with the same number of replacement Engines as
the Engines), such replacement Airframe and Engines (A) to be free and clear of
all Liens (it being understood that, upon such conveyance, such replacement
Airframe and replacement Engines may be subject to Permitted Liens), (B) to have
a value, utility and remaining useful life, determined in accordance with the
Appraisal Procedure as provided in Section 11(c) hereof, at least equal to, and
to be in at least as good operating condition as, the Airframe and the Engines,
if any, so replaced (assuming the Airframe and the Engines were maintained in
accordance with the requirements of this Agreement, whether or not they are in
fact so maintained), and (C) to be a like Airbus A320-231 model aircraft with
equivalent or better modification status delivered by the Manufacturer not
earlier than June 30, 1988 and, in the case of Engines, in compliance with
Section 11(b); provided that if Lessee shall not perform its obligation to
effect such replacement under this clause by the end of the Replacement Period,
Lessee shall then be deemed to have elected to


                                      -66-
   68
comply, and shall comply, with the provisions of clause (ii) of this Section
11(a); provided, further, that the payment specified therein shall be deemed to
have become due and payable on the Stipulated Loss Value Date occurring on or
immediately preceding the last day of the Replacement Period. Upon compliance
with the foregoing, Lessor will, subject to the rights of any insurers, transfer
to Lessee, "AS IS, WHERE IS," without recourse, representation or warranty
(except a warranty that such Airframe and Engines are free and clear of Lessor's
Liens), all of Lessor's right, title and interest, if any, in and to the
Airframe and the Engines suffering the Event of Loss as well as all of Lessor's
right, title and interest in and to any Engine constituting part of the Aircraft
and replaced as provided above but not installed thereon at the time of the
Event of Loss. For all purposes hereof, a replacement Airframe shall be deemed
part of the property leased hereunder and shall be deemed the "Airframe" as
defined herein. No Event of Loss resulting in replacement of the Airframe or
Engines under this Section 11(a)(i) shall result in any reduction of Rent.

                  (ii) On a Stipulated Loss Value Date on or before one hundred
twenty (120) days after the date of the Event of Loss (or, if earlier, with
respect to insurance proceeds, on the date on which insurance proceeds with
respect to the Event of Loss are received by the loss payee) Lessee shall pay to
Lessor in immediately available funds the sum of (A) the Stipulated Loss Value
of the Aircraft as shown on Exhibit A for such Stipulated Loss Value Date, plus
all Basic Rent or Renewal Rent, as the case may be, payable on each Basic Rent
Payment Date or Renewal Rent Payment Date, respectively, prior to the date of
payment of such Stipulated Loss Value which has not been paid when due, plus, if
such Stipulated Loss Value Date is also a Basic Rent Payment Date or a Renewal
Rent Payment Date, the amount of Basic Rent or Renewal Rent, as the case may be,
payable by Lessee on such Stipulated Loss Value Date, or, if such Stipulated
Loss Value Date occurs after the last day of the Term, plus an amount equal to
the average daily Basic Rent or Renewal Rent, as the case may be, in effect on
the last day of the Term, for each day from and including the last day of the
Term to and excluding such Stipulated Loss Value Date, and (B) all Supplemental
Rent payable, whereupon (1) the obligation of Lessee to pay Basic Rent or
Renewal Rent, as the case may be, hereunder with respect to the Aircraft for any
period commencing after the date on which such Stipulated Loss Value is paid
shall terminate; provided that Lessee shall remain liable for, and shall pay on
or before the date the Stipulated Loss Value and Supplemental Rent are


                                      -67-
   69
paid, all payments of Basic Rent or Renewal Rent, as the case may be, for the
Aircraft due on or before the date of such payment of Stipulated Loss Value and
Supplemental Rent, (2) the Term shall terminate with respect to such Aircraft,
and (3) Lessor will, subject to the rights of any insurers, transfer to Lessee,
"AS IS, WHERE IS," without recourse, representation or warranty (except a
warranty that such Airframe and Engines are free and clear of Lessor's Liens),
all of Lessor's right, title and interest, if any, in and to the Airframe and
Engines suffering the Event of Loss, as well as all of Lessor's right, title and
interest, if any, in and to any Engine constituting part of the Aircraft but not
installed thereon at the time of the Event of Loss.

            (b) Event of Loss with Respect to an Engine. Upon an Event of Loss
with respect to an Engine only, Lessee shall give Lessor prompt written notice
thereof and shall, at its own cost and expense, within sixty (60) days after
such occurrence convey or cause to be conveyed to Lessor as replacement for the
Engine suffering an Event of Loss, title to another IAE Model V2500 engine of
like model and equivalent or better modification status or, at Lessee's option,
an IAE engine of an improved model, in each such case which has a value,
remaining useful life and utility determined in accordance with the Appraisal
Procedure at least equal to such Engine and is suitable for installation and use
on the Airframe without diminishing the value, remaining useful life or utility
of such Airframe, free of all Liens (it being understood that, upon such
conveyance, such replacement Engine may be subject to Permitted Liens) and being
in as good operating condition as (including no greater number of cycles or
hours than) the Engine being replaced assuming the Engine being replaced was
serviceable and otherwise in the condition and repair required by the terms
hereof immediately prior to the Event of Loss. Prior to or at the time of any
such conveyance, Lessee, at its own cost and expense, will (i) furnish Lessor
with a full warranty bill of sale, in form and substance reasonably satisfactory
to Owner Participant and Indenture Trustee, as applicable, with respect to such
replacement Engine; (ii) cause supplements, in form and substance reasonably
satisfactory to Owner Participant and Indenture Trustee (if the Lien of the
Indenture has not been discharged), subjecting such replacement Engine to this
Lease, the Indenture (if in effect) and the Trust Agreement (if in effect), to
be duly executed by Lessee, if applicable, and duly filed for recordation
pursuant to the Federal Aviation Act; (iii) furnish Lessor and Indenture Trustee
(if the Lien of the Indenture has not been discharged) with such evidence


                                      -68-
   70
of title to such Replacement Engine and of compliance with the insurance
provisions of Section 12 hereof with respect to such Replacement Engine as Owner
Participant or Indenture Trustee (if the Lien of the Indenture has not been
discharged) may reasonably request; (iv) furnish Owner Participant and Indenture
Trustee (if the Lien of the Indenture has not been discharged) with an opinion
of Lessee's counsel addressed to such parties and to Lessor to the effect that
title to such Replacement Engine has been duly conveyed to Lessor free and clear
of all Liens (except Permitted Liens), and is duly leased hereunder and subject
to the Lien of the Indenture (if it has not been discharged), the instruments
subjecting such Replacement Engine to the Lien of the Indenture and the Lease,
and subjecting to any relevant Assigned Sublease and Sublease Agreement, as the
case may be, have been duly filed for recordation pursuant to the Federal
Aviation Act or any other law then applicable to the registration of the
Aircraft, and no further action, filing or recording of any document is
necessary in order to establish and perfect, in the United States and, if the
Aircraft is registered outside the United States, in the jurisdiction of
registration, the legal title to such Replacement Engine and the Lien of the
Indenture on such Replacement Engine; (v) furnish a certificate signed by a
Responsible Officer of Lessee certifying that, upon consummation of such
replacement, no Default or Event of Default will exist hereunder; (vi) furnish
such documents and evidence with respect to Lessee, Owner Participant or
Indenture Trustee (if the Lien of the Indenture has not been discharged), as
such parties or their respective counsel may reasonably request in order to
establish the consummation of the transactions contemplated by this Section
11(b), the taking of all corporate proceedings in connection therewith and
compliance with the conditions set forth in this Section 11(b), in each case in
form and substance satisfactory to such party; (vii) furnish such Uniform
Commercial Code financing statements covering the Replacement Engine as may be
requested by Lessor or Indenture Trustee (if the Lien of the Indentures has not
been discharged); (viii) furnish Owner Participant with an opinion of tax
counsel mutually satisfactory to Owner Participant and Lessee and which opinion
is reasonably satisfactory to Owner Participant to the effect that such
replacement will have no adverse tax consequences to Lessor and Owner
Participant; (ix) furnish the appraisal referred to above; and (x) furnish Owner
Trustee and Indenture Trustee with the opinion of counsel to Lessee specified in
Section 5.06(a)(5)(i) of the Indenture. Upon full compliance by Lessee with the
terms of this Section 11(b),


                                      -69-
   71
Lessor will, subject to the rights of any insurers, transfer to Lessee, "AS IS,
WHERE IS" without recourse, representation or warranty (except a warranty that
such Engine is free and clear of Lessor's Liens), all of Lessor's right, title
and interest, if any, in the Engine which suffered the Event of Loss. For all
purposes hereof, each such Replacement Engine shall be deemed an "Engine" as
defined herein and shall be deemed part of the same Aircraft as was the Engine
replaced thereof. No Event of Loss covered by this Section 11(b) shall result in
any reduction in Rent.

            (c) Conveyance of Replacement Airframe. Prior to or at the time of
any conveyance of a replacement Airframe pursuant to Section 11(a) above,
Lessee, at its own cost and expense, will furnish Lessor with the following
documents which shall have been duly authorized, executed and delivered by the
respective parties thereto and shall be in full force and effect on said date:
(i) a full warranty bill of sale, in form and substance satisfactory to Owner
Participant and Indenture Trustee (if the Lien of the Indenture has not been
discharged), and an AC Form 8050-2 Bill of Sale (or such other form of bill of
sale as may be approved by the FAA on said date), executed by the owner thereof,
in favor of Lessor and, cause supplements, reasonably satisfactory to Owner
Participant and Indenture Trustee (if the Lien of the Indenture has not been
discharged), to this Lease, the Indenture (if then in effect) and the Trust
Agreement (if then in effect), with respect to such replacement Airframe and to
be duly filed for recordation pursuant to the Federal Aviation Act or other
applicable Governmental Entity; (ii) the certificate specified in Section 12(f)
hereof demonstrating compliance with the insurance requirements of Section 12
with respect to the replacement Airframe and Engines; (iii) an opinion
(addressed to Indenture Trustee, Lessor, and Owner Participant) of Lessee's
counsel (and such other evidence of title as Owner Participant or Indenture
Trustee (if the Lien of the Indenture has not been discharged) may reasonably
request) to the effect that, upon such conveyance, Lessor will acquire good
title to such replacement Airframe free and clear of all Liens (it being
understood that, upon such conveyance, such replacement Airframe may be subject
to Permitted Liens), that such replacement Airframe will be leased hereunder to
the same extent as the Airframe replaced thereby and will be subject to the Lien
of the Indenture (if it has not been discharged), the instruments subjecting
such Replacement Airframe and Replacement Engine to the Lien of the Indenture
and the Lease, and subjecting to any relevant


                                      -70-
   72
Assigned Sublease and Sublease Assignment, as the case may be, have been duly
filed for recordation pursuant to the Federal Aviation Act or any other law then
applicable to the registration of the Aircraft, and no further action, filing or
recording of any document is necessary in order to establish and perfect, in the
United States and, if the Aircraft is registered outside the United States, in
the jurisdiction of registration, the legal title to such Replacement Airframe
and Replacement Engine and the Lien of the Indenture on such Replacement
Airframe and Replacement Engine; and that Lessor, and Indenture Trustee as
assignee of Lessor, is entitled to the benefits of Section 1110 of Title 11 of
the United States Code with respect to such replacement airframe and engines to
the same extent as with respect to the Airframe and Engines then installed
thereon prior to such replacement; (iv) a certificate signed by a Responsible
Officer of Lessee certifying that, upon consummation of such replacement, no
Default or Event of Default will exist hereunder; (v) such documents and
evidence with respect to Lessee, Owner Participant or Indenture Trustee (if the
Lien of the Indenture has not been discharged), as such parties or their
respective counsel may reasonably request in order to establish the consummation
of the transactions contemplated by this Section 11(c), the taking of all
corporate proceedings in connection therewith and compliance with the conditions
set forth in this Section 11(c), in each case in form and substance satisfactory
to each such party, including evidence that the Aircraft of which the
replacement Airframe is a part has been duly certificated by the FAA as to type
and airworthiness in accordance with the terms of this Lease and application for
registration of such replacement Airframe in the name of Lessor has been duly
made with the FAA or other applicable Governmental Entity and Lessee has
temporary or permanent authority to operate the replacement Airframe; (vi)
furnish such Uniform Commercial Code financing statements covering the
replacement Airframe as may be reasonably requested by Lessor or Indenture
Trustee; (vii) furnish Owner Participant with an opinion of tax counsel mutually
satisfactory to Owner Participant and Lessee and which opinion is reasonably
satisfactory to Owner Participant to the effect that such replacement will have
no adverse tax consequences to Lessor and Owner Participant; (viii) an appraisal
prepared in accordance with the Appraisal Procedure which confirms that the
replacement Airframe and any replacement Engine has a value, utility and
remaining useful life at least equal to that of the Airframe and Engines which
suffered the Event of Loss assuming that the same were maintained in accordance
with the requirements of this Lease whether or not they are in fact so
maintained; and (ix) furnish Owner Trustee and


                                      -71-
   73
Indenture Trustee with the opinion of counsel to Lessee specified in Section
5.06(a)(5)(i) of the Indenture. Upon full compliance by Lessee with the terms of
this Section 11(c), Lessor will, subject to the rights of any insurers, transfer
to Lessee "AS IS, WHERE IS," without recourse, representation or warranty
(except a warranty that such Airframe is free and clear of Lessor's Liens), all
of Lessor's right, title and interest in and to the Aircraft which suffered the
Event of Loss. No Event of Loss with respect to the Aircraft under the
circumstances contemplated by the terms of this Section 11(c) shall result in
any reduction in Rent.

            For all purposes of this Lease, each such replacement Aircraft
(together with any Engines constituting part of the Aircraft being replaced as
to which an Event of Loss has not occurred) shall be deemed part of the property
leased hereunder and shall be deemed the "Aircraft" as defined herein.

            (d) Application of Proceeds and Payments. Any payments received at
any time by Lessor or by Lessee from any insurer (including a Governmental
Entity providing an indemnity in lieu thereof) with respect to an Event of Loss
shall be applied in the manner specified in Sections 12(c) and (e) hereof.
Subject to Section 11(f) below, any payments (other than insurance or such
indemnity proceeds) received at any time by Lessor or Lessee from any
Governmental Entity or other Person with respect to an Event of Loss will be
applied as follows (after reimbursement of Lessor, Indenture Trustee and Owner
Participant for their reasonable out-of-pocket costs and expenses):

                  (i) unless clause (ii) below is applicable, so much of such
payments as shall not exceed the Stipulated Loss Value and other payments
required to be paid by Lessee pursuant to Section 11(a)(ii) of this Lease shall
be paid to Lessor in reduction of Lessee's obligation to pay such Stipulated
Loss Value and other payments, if not already paid by Lessee, or, if already
paid by Lessee, shall (unless a Default or an Event of Default shall have
occurred and be continuing) be applied by Lessor to reimburse Lessee for its
payment of such Stipulated Loss Value and other payments and the balance, if
any, of such payment remaining thereafter shall be paid over to, or retained by,
Lessor; or

                  (ii) if such payments are received as a result of an Event of
Loss with respect to the Airframe or an Engine which is being replaced pursuant
to Section


                                      -72-
   74
11(a)(i) or Section 11(b) hereof, all such payments shall be paid over to, or
retained by, Lessee if Lessee shall have fully performed or, concurrently
therewith fully performs, the terms of Sections 11(a)(i) and (c) or Section
11(b) hereof, as the case may be, and of Section 15 hereof with respect to the
Event of Loss for which such payments are made and if no Default or Event of
Default shall have occurred and be continuing.

            (e) Requisition for Use by Government with Respect to the Aircraft.
Subject to Section 11(f) below, in the event of the requisition for use by a
Governmental Entity of the Aircraft, the Airframe or an Engine (other than a
requisition constituting an Event of Loss), Lessee shall promptly notify Lessor
and Indenture Trustee (if the Lien of the Indenture has not been discharged)
thereof and all of Lessee's obligations under this Lease with respect to such
Airframe or Engine shall continue to the same extent as if such requisition had
not occurred. All payments received by Lessor or Lessee from the Governmental
Entity for the use of such Airframe or Engine during the Term shall be paid over
to, or retained by, Lessee if no Default or Event of Default shall have occurred
and be continuing; and all other payments received by Lessor or Lessee from the
Governmental Entity shall be paid over to, or retained by, Lessor. If the
Airframe and such Engines or engines are not returned by the end of the Term, an
Event of Loss shall be deemed to have occurred on the last day of the Term and,
on the last day of the Term, Lessee shall either pay to Lessor the amount
provided herein for an Event of Loss to the Airframe and such Engines or engines
on such date or provide a replacement Aircraft and Engine on such date in the
condition provided for in Section 16 and Exhibit E. In the event of the
requisition for use by the Governmental Entity of any Engine without the
requisition for use of the Airframe, Lessee will replace such Engine hereunder
by complying with the terms of Section 11(b) to the same extent as if an Event
of Loss had occurred with respect to such Engine, and thereafter any payments
received by Lessor or Lessee from the Governmental Entity with respect to such
requisition shall be paid over to, or retained by, Lessee.

            (f) Application in Default. Any amount referred to in clause (i) or
(ii) of Section 11(d) or Section 11(e) which is otherwise payable to Lessee
shall not be paid to Lessee, or, if it has been previously paid to or retained
by Lessee, shall be paid by Lessee to Lessor, if at the time of such payment or
retention a Default or an Event of Default shall have occurred and be
continuing. In such case, all


                                      -73-
   75
such amounts shall be paid to and held by Indenture Trustee so long as the Lien
of the Indenture shall not have been discharged and thereafter by Lessor as
security for the obligations of Lessee, or, at the option of Lessor or the
Indenture Trustee, as the case may be, applied by Lessor or the Indenture
Trustee, as the case may be, toward payment of any of Lessee's obligations at
the time due hereunder, as Lessor or the Indenture Trustee, as the case may be,
may elect, including, without limitation, by reason of this Lease being declared
or deemed in default. At such time as there shall not be continuing any such
Event of Default or Default, all such amounts at the time held by Lessor or
Indenture Trustee in excess of the amount, if any, which Lessor or Indenture
Trustee has elected for application as provided above, shall be paid to Lessee.

            Section 12. Insurance.

            (a) Public Liability and Property Damage Insurance. Lessee will
carry and maintain in effect, or cause to be carried and maintained in effect,
at its own cost and expense, with Approved Insurers, comprehensive aircraft and
general public liability insurance (including, without limitation, contractual
liability, liability war risk and passenger legal liability products, completed
operation liability covering maintenance of aircraft, but excluding
manufacturer's product liability insurance), and property damage insurance with
respect to the Aircraft, in an amount not less than three hundred fifty million
dollars ($350,000,000), combined single limit, per occurrence or such higher
amount, and of such type and terms, as are customarily carried by prudent
Certificated Air Carriers, similarly situated to Lessee, operating aircraft of
similar size and engines and as hereinafter provided. Each and any policy of
insurance carried in accordance with this Section 12(a), and each and any policy
obtained in substitution or replacement for any of such policies, (i) shall
designate Lessor (in both its individual and trustee capacity), Owner
Participant, Indenture Trustee (in both its individual and trustee capacity) and
the other Indemnitees and their respective permitted assigns, as additional
insureds as their interests may appear (but without imposing upon any such
Person any obligation imposed upon the insured, including, without limitation,
the liability to pay any premiums for any such policies), (ii) shall expressly
provide that, in respect of the interests of Lessor, Owner Participant,
Indenture Trustee and the other Indemnitees and their respective permitted
assigns, in such policies, the insurance shall not be invalidated as to an
insured or


                                      -74-
   76
additional insured by any act or omission of Lessee or any other insured or
additional insured and shall insure Lessor, Owner Participant, Indenture Trustee
and the other Indemnitees and their respective permitted assigns, regardless as
to any insured or additional insured of any breach or violation by Lessee or any
other insured or additional insured of any warranty, declaration or condition
contained in such policies, (iii) shall provide that if such insurance is
cancelled for any reason whatsoever, or is changed in any adverse way with
respect to the interests of Lessor, Owner Participant, Indenture Trustee and the
other Indemnitees or if such insurance is allowed to lapse for non-payment of
premium, such cancellation, change or lapse shall not be effective as to Lessor,
Owner Participant, Indenture Trustee and the other Indemnitees, and their
respective permitted assigns, until thirty (30) days, in each instance (seven
(7) days or such lesser period of time as is the insurance industry standard for
war/allied perils coverage), after notice to Lessor, Owner Participant and
Indenture Trustee from such insurer or insurers, of such prospective
cancellation, change or lapse, (iv) shall include coverage for any country in or
over which the Aircraft is located or operated, and (v) shall provide that, as
against Lessor, Owner Participant, Indenture Trustee and the other Indemnitees,
and their respective permitted assigns, each insurer shall waive any rights of
set-off, counterclaim or any other deduction, whether by attachment or
otherwise, and waives any rights it may have to be subrogated to any right of
any insured against Lessor, Owner Participant, Indenture Trustee, or the other
Indemnitees, or their respective permitted assigns, with respect to the
Aircraft. Each liability policy shall be primary without right of contribution
from any other insurance which may be carried by Lessor, Owner Participant,
Indenture Trustee or the other Indemnitees, or their respective permitted
assigns, and shall expressly provide that all of the provisions thereof shall
operate in the same manner as if there were a separate policy covering each
insured, provided, that such policies shall not operate to increase the
insurer's limit of liability. Lessee shall cause its insurers to agree that the
indemnity and hold harmless provisions of Section 13 are insured as a
contractual assumption of liability by Lessee's insurers, subject to the terms,
coverage, conditions, limitations and exclusions of the policy of insurance.
Without limiting the foregoing, the type and amount of the insurance carried by
Lessee hereunder shall be no less in amount and no less comprehensive or
favorable to Lessor, Owner Participant, Indenture Trustee and the other
Indemnitees then that


                                      -75-
   77
carried by Lessee with respect to other A320-231 aircraft or similar-size
aircraft owned or leased by Lessee.

            (b) Insurance Against Loss or Damage. Lessee, at its own expense,
will maintain in effect, or cause to be carried and maintained in effect, with
Approved Insurers "all-risk" ground and flight aircraft hull insurance (which
shall include, but not be limited to, hijacking, a disappearance clause and
coverage against strikes, riots, commotions or labor disturbances, air piracy,
malicious acts or acts of sabotage and unlawful seizure or wrongful exercise of
control of the Aircraft in flight by a person on board such Aircraft acting
without the consent of Lessee) covering the Aircraft, and "all-risk" coverage
including transit insurance with respect to Engines and Parts while not
installed on such Aircraft or an aircraft, which in each case considering all
policy terms, limitations and exclusions is of the type, terms and amount
customarily maintained by prudent Certificated Air Carriers similarly situated
to Lessee and operating similar size aircraft and engines and as hereinafter
provided. Lessee shall also maintain, or cause to be maintained, war risk and
allied perils hull insurance reasonably acceptable to Lessor with Approved
Insurers. In addition, at least ten (10) Business Days (or, in the case of an
emergency, at least two (2) Business Days) prior to permitting the Aircraft,
Airframe or Engines to be operated or located outside of the United States of
America, other than in Canada or Mexico, Lessee shall notify Lessor thereof. If
Owner Participant or Indenture Trustee reasonably requests at any time and if
such insurance is then customarily being obtained by or for Persons leasing or
financing similarly-sized aircraft operating on similar routes to operators
located in the jurisdiction of Lessee's or, if a Permitted Sublease is in
effect, the Permitted Sublessee's jurisdiction of domicile, Lessee shall pay or
reimburse Lessor for political risk, repossession, expropriation, confiscation
and similar insurance as Lessor may arrange or cause to be arranged; provided
that Indenture Trustee shall not be obligated to request such insurance and
shall not be liable for any failure to request such insurance. Anything herein
to the contrary notwithstanding, at all times while the Aircraft is subject to
this Lease, the insurance required by this Section 12(b) shall be for an amount
on an "agreed value" basis not less than the Stipulated Loss Value from time to
time determined for the Aircraft. Without limiting the foregoing, the type and
amount of insurance carried by Lessee hereunder shall be no less comprehensive
or favorable to Lessor, Owner Participant, Indenture Trustee and the


                                      -76-
   78
other Indemnitees than that carried by Lessee with respect to similar-size
aircraft owned or leased by Lessee.

            Each and any policy of insurance obtained and maintained pursuant to
this Section 12(b), and each and any policy obtained in substitution or
replacement for any such policies, (i) shall designate Lessor as owner of the
Aircraft, shall designate, so long as the Lien of the Indenture has not been
discharged, Indenture Trustee and, thereafter, Lessor, as sole loss payee, as
provided below and shall designate Lessor, Owner Participant, Indenture Trustee
(in both its individual capacity and its trustee capacity) and the other
Indemnitees and their respective permitted assigns as additional insureds, as
their respective interests may appear (but without imposing upon Lessor, Owner
Participant, Indenture Trustee and their respective permitted assigns, any
obligation imposed upon the insured, including, without limitation, the
liability to pay any premiums for any such policies), (ii) shall expressly
provide that, in respect of the interests of such an additional insured and its
permitted assigns, in such policies, the insurance shall not be invalidated as
to an insured by any act or omission of Lessee or any other additional insured,
and shall insure each such additional insured and its permitted assigns,
regardless of any breach or violation of any warranty, declaration or condition
contained in such policies by the Lessee or another additional insured, (iii)
shall provide that if such insurance is cancelled for any reason whatsoever, or
is changed in any adverse way with respect to the interests of Lessor, Owner
Participant, Indenture Trustee and to the other Indemnitees and their respective
permitted assigns, or if such insurance is allowed to lapse, such cancellation,
change or lapse shall not be effective as to Lessor, Owner Participant,
Indenture Trustee, the other Indemnitees or their respective permitted assigns,
until thirty (30) days (seven (7) days or such lesser period of time as is the
insurance industry standard for war/allied perils coverage) after written notice
to Lessor, Owner Participant and Indenture Trustee from such insurer or
insurers, as the case may be, of such prospective cancellation, change or lapse,
(iv) shall include coverage for any country in or over which the Aircraft may at
any time be located or operated, (v) shall provide that, as against Lessor,
Owner Participant, Indenture Trustee the other Indemnitees and their respective
permitted assigns, each insurer shall waive any rights of set-off, counterclaim
or any other deduction, whether by attachment or otherwise, and waives any
rights it may have to be subrogated to any right of any insured


                                      -77-
   79
against Lessor, Owner Participant, Indenture Trustee and the other Indemnitees
and their respective permitted assigns, with respect to the Aircraft, (vi) shall
provide that in the event of any damage or loss which is an Event of Loss
hereunder and which results in a payment, such payment shall be payable directly
to Indenture Trustee as sole loss payee, so long as the Lien of the Indenture
shall not have been discharged and thereafter to Lessor, as sole loss payee, and
(vii) shall provide that in the event of any damage or loss which is not an
Event of Loss hereunder and which results in a payment, such payment shall be
payable directly to Indenture Trustee, as sole loss payee for the account of all
interests, so long as the Lien of the Indenture shall not have been discharged
and thereafter to Lessor, as sole loss payee for the account of all interests.
The insurance required under this Section 12(b) may incorporate deductible
amounts which shall not exceed one million dollars ($1,000,000).

            Each of Lessor and Owner Participant shall have the right to carry
additional and separate excess or contingent insurance for its own benefit at
its own expense, without, however, thereby limiting Lessee's obligations under
this Section 12, and Lessee shall not carry any such insurance if it would
conflict with or adversely affect other insurance carried by Lessor or Owner
Participant. Lessee shall have the right to carry insurance in excess of the
amounts required hereunder and the proceeds of such excess insurance shall be
payable to Lessee, provided, however, that such insurance does not conflict with
or adversely affect the insurance required hereunder or any excess or contingent
insurance carried by Lessor or Owner Participant. Lessee shall give Lessor
reasonable prior written notice of any insurance to be carried by Lessee in
addition to that required to be carried by Lessee as provided herein.

            In the event that separate policies are maintained to cover
"all-risk" ground and flight aircraft, hull and war risks and allied perils
insurance, Lessee shall include a 50/50 provisional claims settlement clause as
contained in the policies of insurance maintained by Lessee with respect to all
other aircraft in Lessee's fleet, and a copy of the 50/50 provisional claims
settlement clause in effect on the Restatement Date shall be attached to the
insurance certificate issued on the Restatement Date.

            (c) Application of Insurance Proceeds for an Event of Loss. It is
agreed that insurance payments which


                                      -78-
   80
arise from insurance required to be carried by Lessee pursuant to this Section
12 and received as the result of the occurrence of an Event of Loss shall be
applied as follows (after reimbursement of Lessor, Owner Participant and
Indenture Trustee for their reasonable out-of-pocket costs and expenses):

                  (i) unless clause (ii) below is applicable, so much of such
payments as shall not exceed the Stipulated Loss Value and other payments
required to be paid by Lessee pursuant to Section 11(a)(ii) of this Lease shall
be paid to Indenture Trustee so long as the Lien of the Indenture has not been
discharged and thereafter to Lessor in reduction of Lessee's obligation to pay
such Stipulated Loss Value and any other payments if not already paid by Lessee,
or, if already paid by Lessee, shall (unless a Default or an Event of Default
shall have occurred and be continuing) be applied by Indenture Trustee or
Lessor, as the case may be, to reimburse Lessee for its payment of such
Stipulated Loss Value and other payments and the balance, if any, of such
payment remaining thereafter shall be paid over to, or retained by, Lessor; or

                  (ii) if such payments are received as a result of an Event of
Loss with respect to the Airframe or an Engine which is being replaced pursuant
to Section 11(a)(i) or Section 11(b) hereof, all such payments shall be paid
over by the Indenture Trustee or Lessor, as the case may be, to, or retained by,
Lessee if Lessee shall have fully performed or, concurrently therewith fully
performs, the terms of Section 11(a)(i) and (c) or Section 11(b) hereof, as the
case may be, and of Section 15 hereof with respect to the Event of Loss for
which such payments are made and if no Default or Event of Default shall have
occurred and be continuing.

            (d) Application of Insurance Proceeds for Other than an Event of
Loss. The insurance payments of any property damage loss to the Airframe or any
Engine not constituting an Event of Loss with respect thereto will be applied in
payment for the actual costs of repairs or for replacement property which Lessee
has incurred in accordance with the terms of Section 9, 11 or 12(c) of this
Lease against such documentation evidencing payment by Lessee as Lessor may
reasonably request to reimburse Lessee for such repairs or replacements already
paid for by Lessee, and any balance remaining after compliance with such
Sections with respect to such loss shall be paid to Lessor. Lessee shall be
entitled to receive from the insurer any insurance


                                      -79-
   81
proceeds not in excess of five hundred thousand dollars ($500,000) as soon as
such funds are paid and shall promptly receive such additional insurance
proceeds from the loss payee upon invoices for repair work in progress,
replacement parts which are ordered or for work completed as provided above in
this Section 12(d). Any amount referred to in this Section 12(d) which is
payable to Lessee shall not be paid to Lessee if at the time of such payment any
Default or Event of Default shall have occurred and be continuing, but shall be
held by Lessor as security for the obligations of Lessee under this Lease or
applied as provided in Section 12(e).

            (e) Application in Default. Any amount referred to in clause (ii) of
Section 12(c) or Section 12(d) which is otherwise payable to Lessee shall not be
paid to Lessee, or if it has been previously paid to or retained by Lessee,
shall be paid by Lessee to Indenture Trustee, so long as the Lien of the
Indenture shall not have been discharged, and thereafter to Lessor, if at the
time of such payment or retention a Default or an Event of Default shall have
occurred and be continuing. In such case, all such amounts shall be paid to and
held by Indenture Trustee, so long as the Lien of the Indenture shall not have
been discharged, and thereafter held by Lessor as security for the obligations
of Lessee, or, at the option of Indenture Trustee or Lessor, applied by
Indenture Trustee or Lessor toward payment of any of Lessee's obligations at the
time due hereunder, including, without limitation, by reason of this Lease being
declared or deemed declared in default, as Indenture Trustee or Lessor may
elect. At such time as there shall not be continuing any such Event of Default
or Default, all such amounts at the time held by Indenture Trustee or Lessor in
excess of the amount, if any, which Indenture Trustee or Lessor has elected for
application as provided above, shall be paid to Lessee.

            (f) Certificates. On or before the Delivery Date, and thereafter on
any renewal by the Lessee of the insurance required hereby (but in no event less
than once in every twelve (12) month period), Lessee will furnish to Lessor and
Indenture Trustee a certificate executed and delivered by an Approved Insurer or
the Approved Broker, describing in reasonable detail, and in accordance with
customary practice, insurance carried on the Aircraft and Lessee shall also
furnish an opinion or report by the Approved Insurer or the Approved Broker
certifying that the insurance then maintained on the Aircraft complies with the
terms of this Lease. Lessee will cause the Approved Broker


                                      -80-
   82
to agree to advise Lessor, Owner Participant and Indenture Trustee in writing at
least thirty (30) days (seven (7) days or such lesser period of time as is the
insurance industry standard for war/allied perils coverage) prior to the
expiration, non-renewal, termination or cancellation for any reason (including,
without limitation, failure to pay premium therefor) or material modification of
any such insurance.

            In the event Lessee shall fail to maintain insurance as herein
provided, Lessor, Owner Participant or Indenture Trustee at their respective
options, may provide such insurance and, in such event, Lessee shall, upon
demand, reimburse Lessor, as Supplemental Rent, or any other such other Person
who may have provided such insurance, for the cost thereof.

            (g) Reinsurance. Lessee (or if a Permitted Sublease is in effect,
the Permitted Sublessee) may carry primary insurance outside of the aviation
insurance markets in New York, London or Paris if the relevant primary insurer
shall have obtained reinsurance and such reinsurance (i) is on the same terms as
the original insurance and includes the provisions required by this Agreement;
(ii) provides in case of any bankruptcy, insolvency, liquidation, dissolution or
similar proceedings of or affecting the original insurer that the reinsurers'
liability will be to make such payment as would have fallen due under the
relevant policy of reinsurance if the original insurer had (immediately before
such bankruptcy, insolvency, liquidation, dissolution or similar proceedings)
discharged its obligations in full under the original insurance policies in
respect of which the then relevant policy of reinsurance has been effected; and
(iii) contains a "cut-through" clause in the following form (or otherwise,
satisfactory to Owner Participant): "The Reinsurers and the Reinsured hereby
mutually agree that in the event of any claim arising under the reinsurances in
respect of a total loss or other claim where as provided by the Amended and
Restated Aircraft Lease Agreement [GPA 1990 AWA-13] dated as of November 26,
1996 and made between Wilmington Trust Company, as Owner Trustee, and America
West Airlines, Inc. such claim is to be paid to the person named as sole loss
payee under the primary insurances, the Reinsurers will in lieu of payment to
the original insured, its successors in interest and assigns pay to the person
named as sole loss payee under the primary insurances effected by the original
insured that portion of any loss due for which the Reinsurers would otherwise be
liable to pay the original insurer (subject to proof of loss), it


                                      -81-
   83
being understood and agreed that any such payment by the Reinsurers will (to the
extent of such payment) fully discharge and release the Reinsurers from any and
all further liability in connection therewith."

            (h) Storage. During any period that the Aircraft is in storage or
otherwise grounded, Lessee may carry or cause to be carried, in lieu of the
insurance required by Sections 12(a) and (b) above, insurance otherwise
conforming with the provisions of said Sections 12(a) and (b) except that the
scope of the risk and the type of insurance, and the amount of the insurance in
the case of the insurance described in Section 12(a) above (but not the amount
of insurance to be carried under Section 12(b) above), shall be the same as from
time to time applicable to similar size passenger aircraft that comprise
Lessee's fleet in similar storage or grounding, and in any event (including,
without limitation, at any time when there shall be in existence a Permitted
Sublease), the same as from time to time customarily carried by
similarly-situated, prudent Certificated Air Carriers for passenger aircraft of
similar size as the Aircraft in similar storage or grounding.

            (i) Amounts Held. So long as no Default or Event of Default has
occurred and is continuing, any amount held by Lessor or Indenture Trustee, as
the case may be, until application by Lessor or Indenture Trustee, as the case
may be, pursuant to this Section 12 shall be invested as provided in Section
21(h) hereof.

            (j) After the Term. Lessee shall continue to maintain at its expense
the insurance described in Section 12(a) for three years after the expiration or
termination of the Basic Term or Renewal Term, if Lessee has elected to renew
the Lease in accordance with Section 20, covering each Indemnitee as its
interest may appear and specifically insuring the indemnity contained in Section
13 to the extent of the coverage of such policy.

            (k) Governmental Indemnity. In lieu of certain of the insurance
described in Section 12 above, Lessee may provide a United States governmental
indemnity, to the extent and subject to the terms and conditions specified in
Section 6(c).

            Section 13. General Indemnity.

            Lessee hereby agrees to indemnify, reimburse, defend and hold
harmless each Indemnitee on a net after-tax


                                      -82-
   84
basis, as provided in Section 10(e), within fifteen (15) days after demand from
and against any and all claims (whether or not based on strict liability),
damages (whether direct, indirect, incidental, special or consequential),
losses, charges, fees, liabilities, obligations, demands, suits, judgments,
actions and other legal proceedings (whether civil or criminal), penalties,
fines, other sanctions, and any reasonable costs and expenses, in connection
herewith, including, without limitation, costs and expenses set forth in Section
21(j) hereof and reasonable attorney's fees and expenses of whatever kind or
nature (any and all of which are hereafter referred to as "Claims") imposed on,
or asserted by or against, or suffered or incurred by, any Indemnitee, from (and
including) the Restatement Date, including, without limitation, injury, death or
property damage of passengers, shippers and others, environmental control, noise
and pollution regulations, which in any way may result from, pertain to, or
arise in any manner out of, or are in any manner related to (1) the Operative
Documents, the Purchase Documents or the Financing Documents, or any of the
transactions contemplated thereby; (2) the Aircraft, the Airframe, any Engine or
any engine used in connection with the Airframe or any Part thereof, including,
but not limited to, (A) the importation, exportation, condition, manufacture,
design, purchase, ownership, registration, reregistration, deregistration (other
than any deregistration caused by the failure of the registered owner of the
Aircraft to be a "citizen of the United States" as defined under the Federal
Aviation Act and the regulations thereunder or to file the documentation
necessary to continue FAA registration of the Aircraft), delivery, nondelivery,
assignment, leasing, subleasing, sub-subleasing, acceptance, rejection,
possession, repossession, control, return, financing, Liens (excluding Lessor's
Liens, Head Lessor's Liens and Lenders' Liens, but including the Lien of the
Indenture), use, performance, modification, maintenance, overhaul, operation,
pooling, interchange, repair, testing, sale, return or other disposition or
application of the Aircraft, the Airframe, any Engine, any engine used in
connection with the Airframe or any Part (including, but not limited to, latent
and other defects whether or not discoverable by Lessee or Lessor, Claims
related to any actual or alleged violation of Law, loss or damage to any
property of passengers, shippers or otherwise or any Claim related to patent,
copyright, trademark or other infringement) either in the air or on the ground,
and, including, without limitation, any interest therein of an Indemnitee or
imposition of a Lien thereon (excluding Lessor's Liens, Head Lessor's Liens and
Lenders'


                                      -83-
   85
Liens but including the Lien of the Indenture), or the rentals, receipts or
earnings therefrom (including, without limitation, the Rent and any other
amounts paid or payable with respect thereto); or (B) any defect in the
Aircraft, the Airframe, any Engine, any engine used in connection with the
Airframe or any Part thereof arising from the material or any article used
therein, whether from the design, testing or use thereof from any maintenance,
service, repair, overhaul or testing of such Aircraft, Airframe, Engine, engine
or Part, or otherwise regardless of when such defect shall be discovered,
whether or not such Aircraft, Airframe, Engine, engine or Part is at the time in
the possession of Lessee, and regardless of where such Aircraft, Airframe,
Engine, engine or Part may then be located; or (3) the breach of any
representation, warranty or covenant made by Lessee hereunder or under any of
the other Operative Documents or any Default or Event of Default; provided,
however, that the indemnity provided for in this Section 13 shall not apply to
any portion of a Claim of an Indemnitee to the extent it results from: (i) the
gross negligence or willful misconduct of such Indemnitee or any of its
directors, officers, employees, servants or agents (except any such gross
negligence or willful misconduct as may be attributed to an Indemnitee due to
its interest in the Aircraft, the Airframe, an Engine, any Operative Document,
any Purchase Document or any Financing Document), (ii) the material breach of
any express representation, warranty or covenant made by such Indemnitee herein
or in any other Operative Document, or the Financing Documents (not resulting
from a breach by Lessee of any of its representations, warranties or covenants
in the Operative Documents or in the Financing Documents), (iii) any Taxes,
whether or not Lessee is required to indemnify such Taxes under Section 10
hereof or the Tax Indemnification Agreement (it being understood that Section 10
hereof and the Tax Indemnification Agreement exclusively provide for Lessee's
liability with respect to Taxes), (iv) any Claim which relates solely to events
which occurred prior to but excluding the Restatement Date (other than Claims
related to the condition, manufacture or design of the Aircraft) and any Claim
concerning payment for or the ownership of Buyer Furnished Equipment, (v) an
underlying act which occurs after the Aircraft has been returned to Lessor in
accordance with the terms hereof and the Term of this Lease has been terminated
or has expired and the return is not related to an Event of Default, (vi) as to
such Indemnitee, an underlying act which occurs after a disposition or other
transfer (voluntary or involuntary) by such Indemnitee of all or any part of its
interest in the


                                      -84-
   86
Aircraft, the Airframe, any Engine, or any Part, or in the Financing Documents,
the Purchase Documents or the Operative Documents, except as contemplated under
or pursuant to the Operative Documents, the Financing Documents or the Purchase
Documents and except as resulting from the exercise of its remedies during the
period while an Event of Default has occurred and is continuing and prior to the
time such Indemnitee has received payment of all amounts owing to it hereunder
or thereunder and except any Claim which is alleged or does relate to the period
prior to such disposition or (vii) the authorization or giving or withholding of
any future amendments, supplements, waivers or consents with respect to any of
the Financing Documents, the Purchase Documents or the Operative Documents,
which amendments, supplements, waivers or consents were not requested by Lessee
or are not required to give effect to the provisions of the Operative Documents,
the Financing Documents or the Purchase Documents (provided, however, in no
event will Lessee be liable for any Claims resulting from, pertaining to or
arising from or related to Lessor's granting or creating a Lessor's Lien or the
granting or creation of a Head Lessor's Lien). Upon full payment of the
indemnities herein, Lessee shall be subrogated to all rights and remedies which
such Indemnitee may have against any third party against whom such Indemnitee
has the right to assert a Claim which arises under any action described in this
Section 13 (except Claims under such Indemnitee's own insurance policies or
under the indemnification provisions of any of the Financing Documents).

            Without limiting Lessee's liability under this Section 13, Lessee
hereby waives and releases any Claim now or hereafter existing against any
Indemnitee, on account of any Claims for or on account of or arising or in any
way connected with injury to or death of personnel of Lessee or loss or damage
to property of Lessee or the loss of use of any property which may result from
or arise in any manner out of or in relation to the importation, exportation,
ownership, purchase, registration, reregistration, deregistration (except as to
Owner Participant or Lessor as and to the extent such Indemnitee is responsible
under the Refunding Agreement for Claims related to such deregistration),
delivery, non-delivery, assignment, leasing, subleasing, manufacture,
acceptance, rejection, possession, return, financing, performance, modification,
maintenance, condition, use, operation, pooling, interchange, repair, testing,
sale, return or other disposition of the Aircraft, the Airframe, any Engine or
any engine used in connection with the Airframe or any Part


                                      -85-
   87
thereof, either in the air or on the ground, or which may be caused by any
defect in such Aircraft, Airframe, Engine, engine or Part from the material or
any article used therein or from the design or testing thereof, or use thereof
or from any maintenance, service, repair, overhaul, or testing of such Aircraft,
Airframe, Engine, engine or Part, claims for infringement, loss of or injury to
any person, loss of or damage to any property or environmental damage,
regardless of when such defect may be discovered, whether or not such Aircraft,
Airframe, Engine, engine or Part is at the time in the possession of Lessee, and
regardless of the location of such Aircraft at any such time except to the
extent that such Claim results from (i) the gross negligence or willful
misconduct of such Indemnitee (except any such gross negligence or willful
misconduct as may be attributed to an Indemnitee due to its interest in the
Aircraft, the Airframe, an Engine, any Operative Document, any Purchase Document
or any Financing Document), (ii) the material breach of any of its express
representations, warranties or covenants hereunder, under any other Operative
Document or Financing Document (not resulting from a breach by Lessee of any of
its representations, warranties or covenants in the Operative Documents or in
the Financing Documents), (iii) any Taxes, whether or not Lessee is required to
indemnify such Taxes under Section 10 hereof or the Tax Indemnification
Agreement (it being understood that Section 10 hereof and the Tax
Indemnification Agreement exclusively provide for Lessee's liability with
respect to Taxes), (iv) any Claim which relates solely to events which occurred
prior to but excluding the Restatement Date (other than Claims related to the
condition, manufacture or design of the Aircraft) and any Claim concerning
payment for or the ownership of Buyer Furnished Equipment, (v) an underlying act
which occurs after the Aircraft has been returned to Lessor in accordance with
the terms hereof and the Term of this Lease has been terminated or has expired
and the return is not related to an Event of Default, (vi) an underlying act
which occurs after a disposition or other transfer (voluntary or involuntary) by
such Indemnitee of all or any part of its interest in the Aircraft, the
Airframe, any Engine, or any Part, or in the Financing Documents, the Purchase
Documents or the Operative Documents (except as contemplated under or pursuant
to the Operative Documents, the Financing Documents or the Purchase Documents
and except as resulting from the exercise of its remedies during the period
while an Event of Default has occurred and is continuing and prior to the time
such Indemnitee has received payment of all amounts owing to it hereunder and
except any Claim which is alleged or does relate to the


                                      -86-
   88
period prior to such disposition), (vii) the authorization or giving or
withholding of any future amendments, supplements, waivers or consents with
respect to any of the Financing Documents, the Purchase Documents or the
Operative Documents, which amendments, supplements, waivers or consents were not
requested by Lessee or are not required to give effect to the provisions of the
Operative Documents, the Financing Documents or the Purchase Documents or (viii)
a Lessor's Lien, a Head Lessor's Lien or a Lenders' Lien attributable to such
Indemnitee.

            Each Indemnitee shall, at Lessee's sole cost and expense and with
Lessee's cooperation, be entitled to conduct the defense of any Claim against
it; provided, however, that Lessee shall, at the request of any Indemnitee and
so long as no Event of Default has occurred and is continuing, assume and
conduct promptly and diligently, at its sole cost and expense, the defense of
such Indemnitee against any Claim of a third party with counsel reasonably
acceptable to such Indemnitee; and provided, further, however, that Lessee shall
have the right as well as the obligation to assume such defense to the extent
required under the terms of the applicable insurance policies so long as no
Default or Event of Default has occurred and is continuing. In the event Lessee
shall so assume the defense of any Claim, such Indemnitee shall cooperate with
Lessee in defending such Claim, but any expenses incurred by such Indemnitee in
connection therewith shall either be paid by Lessee to such Indemnitee in
advance, or reasonable security shall be provided by Lessee to such Indemnitee
for such payments. Neither Lessee nor an Indemnitee shall enter into a
settlement or other compromise with respect to any Claim which Lessee or such
Indemnitee is defending hereunder in excess of $100,000 without the prior
written consent of the other, which consent shall not be unreasonably withheld.

            Each Indemnitee agrees to give Lessee prompt notice of any Claims by
a third party hereunder following such Indemnitee's actual knowledge of such
Claims by third parties, but the failure of such Indemnitee to give the notice
required by this Section 13 shall not constitute a release by Lessor or such
Indemnitee of, or reduce, any of the obligations or liabilities of Lessee to
such Indemnitee in respect of any such Claim or otherwise affect the obligations
or liabilities of Lessee to any Indemnitee in respect of any such Claim, except
to the extent that Lessee's ability to control the defense thereof where Lessee
has the right to control the defense thereof is materially


                                      -87-
   89
prejudiced as a result solely of such failure of such Indemnitee to give such
notice.

            An Indemnitee or Lessee shall supply the other with such information
requested by the other as is reasonably necessary or advisable for the other to
control the defense of a Claim to the extent permitted by this Section .

            Nothing in this Section shall be construed as a guaranty by Lessee
of payments due pursuant to any indebtedness incurred with respect to the
purchase of the Aircraft or of the residual value of the Aircraft.

            Notwithstanding anything herein or in any other Operative Document
to the contrary, with respect to any Claim for which any Indemnitee is entitled
to indemnification under more than one provision of this Lease or any other
Operative Document, such Indemnitee shall be entitled to recovery for such Claim
only pursuant to one such provision as it may select in its sole discretion
(and, for the avoidance of doubt, such Indemnitee shall not be entitled to any
double recovery for the same Claim).

            The indemnities contained in this Section 13 shall continue in full
force and effect notwithstanding the expiration or other termination of this
Lease or any of the other Operative Documents and are expressly made for the
benefit of and shall be enforceable by each Indemnitee.

            Section 14. Liens.

            Lessee shall not directly or indirectly create, incur, assume, or
suffer to exist any Lien on or with respect to the Aircraft, the Airframe, any
Engine or any Part thereof, title thereto, or any interest of Lessor therein or
in this Lease, except (i) the respective rights of Lessor, Lessee, Owner
Participant, Indenture Trustee and any other Indemnitee as herein provided or
provided under the other Operative Documents or the Financing Documents; (ii)
Head Lessor's Liens, Lessor's Liens and Lenders' Liens; (iii) Liens for Taxes
either not yet due or being diligently contested in good faith by appropriate
proceedings in accordance with Section 10 and so long as adequate reserves are
maintained with respect to such Liens and only so long as neither such
proceedings nor such Liens involve any material danger of the sale, forfeiture
or loss of any of the Aircraft, the Airframe or any Engine or any Part, or any
interest of Lessor or Indenture Trustee therein or any risk of criminal
liability of Lessor or Indenture Trustee; (iv)


                                      -88-
   90
inchoate materialmen's, mechanics', workmen's, repairmen's employees', or other
like inchoate Liens arising in the ordinary course of business for sums not
overdue by more than 45 days or being diligently contested in good faith and
only so long as neither such proceedings nor any such Liens involve any material
danger of the sale, forfeiture or loss of any of the Aircraft, the Airframe or
any Engine or any Part, or any interest of Lessor or Indenture Trustee therein;
(v) the rights of other Persons to the extent expressly permitted by the
provisions of Section 6(a), 9(c) or 19; (vi) Liens arising out of any judgment
or award against Lessee (or any Permitted Sublessee) unless the judgment or
award shall not, within thirty (30) days after the entry thereof, have been
discharged, vacated, reversed, or execution thereof stayed pending appeal or
shall not have been discharged, vacated or reversed within thirty (30) days
after the expiration of such stay and only so long as such Liens shall not
involve any material danger of the sale, forfeiture or loss of any of the
Aircraft, the Airframe or any Engine or any Part, or any interest of Lessor or
Indenture Trustee therein and provided that the execution of such judgment or
award or an attachment relating thereto shall not have occurred within such
thirty (30) day period; and, (vii) any other Lien with respect to which Lessee
(or a Permitted Sublessee) shall have provided a bond adequate in the reasonable
opinion of Indenture Trustee (if the Lien of the Indenture has not been
discharged) and Owner Participant. Lessee shall promptly, at its own expense,
take or cause to be taken such action as may be necessary to duly discharge any
Lien (except for the Liens referred to in clauses (i) through (vii) of this
Section 14) directly or indirectly created, incurred, assumed, or suffered to
exist by Lessee if the same shall arise at any time.

            Section 15. Protection of Title and Further Assurances.

            Forthwith upon the execution and delivery of this Lease, the
Indenture, the Trust Agreement, Lease Supplement, Indenture Supplement and Trust
Supplement, and any other supplement from time to time required by the terms
hereof, Lessee will cause this Lease, the Indenture, the Trust Agreement, Lease
Supplement, Indenture Supplement, Trust Supplement and such other supplements to
be duly filed and recorded, and maintained of record, in accordance with the
applicable laws of the government of registry of the Aircraft. If any filing or
recording is reasonably necessary to protect the interests of Lessor or
Indenture Trustee, Lessee shall, at its own cost and expense (except


                                      -89-
   91
it shall be at Lessor's expense if in connection with a change in ownership of
the Aircraft or any other transfer or assignment by Lessor other than as
contemplated hereunder or under the Financing Documents or in connection with an
Event of Default) and upon request by Lessor, cause any financing statements and
any and all additional instruments and other documents, so far as permitted by
applicable Law, to be kept, filed, and recorded and to be re-executed, refiled
and re-recorded at all times in the appropriate office pursuant or in relation
to any applicable Laws of any Governmental Entity, to protect and preserve the
rights and interests of Lessor or Indenture Trustee hereunder, under the
Indenture and in the Aircraft, and Lessee shall furnish to Lessor and Indenture
Trustee, evidence, reasonably satisfactory to Lessor and Indenture Trustee, of
each such filing or refiling and recordation and re-recordation.

            Without limiting the foregoing, Lessee shall do or cause to be done,
at Lessee's cost and expense (except it shall be at Lessor's expense if in
connection with a change in ownership of the Aircraft or any other transfer or
assignment by Lessor other than as contemplated hereunder or under the Financing
Documents or in connection with an Event of Default), any and all acts and
things within its control which may be required under the terms of the Mortgage
Convention to protect and preserve the title of Lessor, the Lien of the
Indenture, this Lease, and the interests of Lessor and Indenture Trustee within
the jurisdiction of any signatory which has ratified the Mortgage Convention in
such jurisdiction and in the territories thereof in which Lessee, any Permitted
Sublessee or any wet sublessee may operate the Aircraft, as Lessor may
reasonably request. Lessee shall also do or cause to be done, at its own expense
(except it shall be at Lessor's expense if in connection with a change in the
ownership of the Aircraft or any other transfer or assignment by Lessor other
than as contemplated hereunder or under the Financing Documents or in connection
with an Event of Default), any and all acts and things which may be required
under the terms of any other Law involving any jurisdiction in which Lessee, any
Permitted Sublessee or any wet lessee may operate the Aircraft, which Lessor may
reasonably request, to protect and preserve the title of the Lessor, this Lease,
the Indenture and Lessor's and Indenture Trustee's interest in the Aircraft and
under any of the Operative Documents or Financing Documents within any such
jurisdiction.

            In addition, at Lessee's expense, Lessee will promptly and duly
execute and deliver to Lessor or Indenture


                                      -90-
   92
Trustee, as applicable, such further documents and assurances and take such
further actions as Owner Participant or Indenture Trustee may from time to time
reasonably request in order to more effectively carry out the intent and purpose
of this Lease and the other Operative Documents and the Financing Documents and
to protect the rights and remedies created or intended to be created in favor of
Lessor or Indenture Trustee hereunder and the other Operative Documents and the
Financing Documents including, without limitation, if reasonably requested by
Owner Participant or Indenture Trustee, at the expense of Lessee (except it
shall be at Lessor's expense if in connection with a change in the ownership of
the Aircraft or any other transfer or assignment by Lessor or Indenture Trustee
other than as contemplated hereunder or under the Financing Documents or in
connection with an Event of Default), the execution and delivery of supplements
or amendments hereto in recordable form, subjecting to this Lease, the Indenture
and the other Financing Documents, any replacement Aircraft or Engine and the
recording or filing of counterparts thereof in accordance with the laws of any
appropriate jurisdiction.

            Section 16. Return of Aircraft and Records.

            (a) Return. On any Return Occasion, Lessee, at its own expense and
risk, shall return the Aircraft to Lessor (or any Person designated by Lessor)
in at least the condition specified in this Section and Exhibit E hereto at any
Lessee system location in the continental United States selected by Lessor, as
Lessor may elect, or such other location as Lessor and Lessee may agree, fully
equipped with all required Engines, or other engines owned by Lessee (which
shall thereupon become Engines as hereinafter provided) meeting the conditions
specified in this Section and Exhibit E, duly installed thereon by delivering
the same to the Lessor at such location. Lessee shall comply with Section 11(b)
and this Section 16 with respect to any engines installed on the Aircraft
returned to Lessor hereunder and meeting the conditions described herein which
were not originally installed on the Aircraft.

            (b) Status Upon Return. Upon any Return Occasion hereunder, the
Aircraft shall be: (i) free and clear of all Liens, except for the Lien of the
Indenture, Head Lessor's Liens, Lessor's Liens and Lenders' Liens, (ii) duly
certified as an airworthy aircraft by the FAA under Part 121 of the regulations
promulgated under the Federal Aviation Act and with a current and valid
Airworthiness Certificate


                                      -91-
   93
installed on the Aircraft, unless such certificate shall have been suspended or
revoked as a result of the suspension or revocation of the registration of the
Aircraft under the Federal Aviation Act due to the ineligibility of the Aircraft
to be registered in the name of Lessor under the Federal Aviation Act (whether
by means of a voting trust agreement or otherwise) in which case the Aircraft
shall nevertheless meet all conditions for such certification and for the
issuance of such certificate; (iii) in full airworthy condition for over water
and EROPS operation according to the FAA standards required to allow the
Aircraft to be operated under, and in full compliance with, such Airworthiness
Certificate and Part 121 of the regulations promulgated under the Federal
Aviation Act for such operation, such compliance to be by means of such
mechanical repairs or modifications or such inspections as may be required
thereby, but not by operational restrictions, by logbook entries or other method
of acceptance of such restrictions; (iv) in full compliance with Lessee's
Maintenance Program; (v) to the extent the owner of the Aircraft is a "citizen
of the United States" within the meaning of Section 40102(a)(15) of the Federal
Aviation Act and reasonably cooperative with Lessee at Lessee's expense with
respect to effecting such registration, duly registered in the name of the
Lessor or other then owner of the Aircraft under the Federal Aviation Act; (vi)
in full compliance with the maintenance and operation provisions of this Lease
and all FAA airworthiness directives, mandatory service bulletins and equivalent
requirements which by their terms require compliance on or before the last day
of the Term (without regard to any deferral, waiver, deviation or exemption
granted by the FAA specifically to Lessee delaying such compliance); (vii) in
good and airworthy operating condition, and in the same condition (including,
without limitation, in a passenger configuration suitable for passenger revenue
service) as when delivered to Lessee hereunder, ordinary wear and tear excepted,
with no open or outstanding deferred maintenance items, scheduled or
unscheduled, with all systems and components fully serviceable and operational
and with no placards restricting operation or use, and (viii) with all remaining
warranties, indemnities, policies and guarantees referred to in Section 5(d)
made available to Lessor in a manner and by documents in form and substance
reasonably satisfactory to Lessor.

            (c) Engines. In the event any engine not owned by Lessor shall be
installed on the Aircraft on any Return Occasion, without limiting Lessee's
obligations under the


                                      -92-
   94
Tax Indemnification Agreement, such engine shall be of the same model and
equivalent modification status as the Engines or, at Lessee's option, an IAE
engine of an improved model suitable for installation and use on the Airframe
without diminishing the value, remaining useful life or utility of such
Airframe, in each such case having a value, remaining useful life and utility at
least equal to (as determined in accordance with the Appraisal Procedure), and
be in an operating condition as good as the Engines, assuming the Engines were
in the condition and repair as required by the terms hereof immediately prior to
such termination and shall conform to the return condition requirements set
forth in this Section 16 and Exhibit E, and Lessee, at its own expense and
concurrently with such delivery, shall cause such engine to become an Engine by
complying with Section 11(b) hereof. Lessee's obligation to comply with the
terms of this Section 16(c) shall be conditioned on Lessor's transferring to
Lessee all of Lessor's right, title and interest in and to any Engine not
installed on the Aircraft at the Return Occasion "AS IS, WHERE IS," without any
representation, warranty or recourse of any kind whatsoever, express or implied,
except a warranty that such Engine is free and clear of Lessor's Liens.

            (d) Records and Documents. Upon the return of the Aircraft, Lessee
shall deliver to Lessor (i) all logs, manuals and data, and inspection,
modification, overhaul and other records, related to the Aircraft, including,
without limitation, those required to be maintained with respect thereto under
applicable rules and regulations of the FAA, together with a detailed
description of the Maintenance Program then applied to the Aircraft and shall
provide Lessor and its designees access to the Maintenance Program which is
sufficient for a Person to maintain the Aircraft under an FAA approved
maintenance program after the Term or to transition maintenance to another
program, including, without limitation, another registry, or, in the event an
Event of Default shall have occurred, to continue to maintain the Aircraft under
the Maintenance Program, in each case as Lessor may reasonably request, and all
documentation with respect to the Aircraft set forth on Exhibit B or otherwise
delivered to Lessee at delivery thereof, and (ii) all records necessary or
required by the FAA to certify and place the Aircraft on an FAA or other
country's, as the case may be, approved maintenance program. All of the
foregoing shall, at Lessee's expense, be up-to-date and in the latest revision
status as of the last day of the Term, including, without limitation, all
software and other electronically-held materials which have been supplied by or
on behalf of


                                      -93-
   95
Manufacturer, Manufacturer's Subsidiary or Original Head Lessee, which must be
updated to the latest revision status as of the last day of the Term within such
software base and all data therein or pertaining thereto shall be deemed
property of Lessor and shall be delivered to Lessor. If hard, i.e.,
non-computerized, copies of English language maintenance records are not
available, then Lessee shall cause the appropriate action to be taken with the
pertinent regulatory agencies to ensure that Lessor and the FAA are provided
with all requested necessary and proper guarantees of methods of compliance,
component overhaul and management, scheduling, quality control, serial number
verification, etc. These records shall be all inclusive to the Aircraft,
Airframe, Engines, components, rotables, and assemblies and, as a minimum,
extend to include all activities associated with each of the last completed
maintenance checks, repairs, scheduled inspections and functional tests, and
overhauls performed under Lessee's Maintenance Program. All components and
assemblies identified with safe life limits shall be identified with their
service histories, accumulated cycles or flight hours as applicable and
remaining service lives on a separate listing. All components and assemblies
which are identified on the maintenance records by part numbers and serial
numbers other than the manufacturer's shall be provided with interchange or
cross reference listing necessary to establish complete traceability. All
documentation, flight, and maintenance records as specified by United States
Federal Aviation Regulations 91.173, 91.174, and each paragraph of regulation
121.380 which normally accompany the transfer of an aircraft which has been
operating in regulated commercial air service, shall be delivered to Lessor with
the Aircraft. Any documents or records required to be delivered hereunder shall
be in English.

            (e) Condition of Aircraft. Upon any Return Occasion, Lessee shall
return such Aircraft to Lessor in such condition that the Aircraft shall also
comply with each and every condition and requirement set forth elsewhere in this
Lease, including Exhibit E hereto.

            (f) Final Inspection. Upon any Return Occasion, Lessee shall make
the Aircraft available to Lessor at the location where the "block 'C' Check" (or
equivalent level designated check or checks) required hereunder to be performed
immediately prior to redelivery is to be performed for detailed inspection of
the documents referred to in paragraph (d) above and the Airframe, Engines and
Parts structure and parts, at Lessee's expense (excluding


                                      -94-
   96
compensation to representatives of Lessor), in order to verify that the
condition of such Aircraft complies with the requirements set forth above (such
inspection being hereinafter referred to as the "Final Inspection"). The Final
Inspection shall be combined with such "block 'C' Check" (or equivalent level
check or checks) and may include such other items as reasonably requested by
Lessor. Lessee shall give Lessor not less than thirty (30) days prior written
notice of the commencement date of such Final Inspection. The period allowed for
the Final Inspection shall be the same period during which such "block 'C'
Check" is being performed and shall have such duration as to permit the opening
of any areas of the Aircraft which are necessary or advisable to satisfy Lessor
as to compliance with the requirements of this Section 16 and Exhibit E. The
Final Inspection shall commence on the date so noticed which shall be on or
before the expiration of the Term with respect to the Aircraft and shall
continue on consecutive days until all activity required above to be conducted
has been concluded. To the extent that any portion of the Final Inspection
extends beyond the expiration of the Term, unless Lessor has terminated the
Lease pursuant to Section 18(g) hereof, the Term with respect to the Aircraft
undergoing the Final Inspection shall be deemed to have been automatically
extended, and all obligations hereunder continued, on a daily basis until the
Final Inspection shall have been concluded and Lessee shall pay Rent during any
such extension in an amount equal to the average daily Basic Rent or Renewal
Rent, as the case may be, paid in respect of the last year of the Basic Term or
Renewal Term, as the case may be (and Stipulated Loss Value during such
extension shall equal the Stipulated Loss Value on the last day of the Basic
Term or Renewal Term, as the case may be); provided, however, that Lessee shall
not be required to pay Rent with respect to the Aircraft during the period of
extension to the extent that Lessor is responsible for the delay in completion
of the Final Inspection. All storage expenses attributable to any Term extension
pursuant to the preceding sentence shall be payable by Lessee, except that
Lessee shall not be liable for any storage expenses which are incurred after the
sixtieth (60th) day after the Term to the extent that storage continues
thereafter due to Lessor's delay in completion of the Final Inspection.

            (g) Aircraft Records and Documents. In order to enable Lessor to
prepare for the Final Inspection of the Aircraft pursuant to Subsection 16(f)
above, Lessee agrees to make available to Lessor at a maintenance base of Lessee
with adequate facilities for short-term maintenance, where


                                      -95-
   97
the Final Inspection is to occur, not later than ten (10) days prior to the
commencement of such Final Inspection, the Aircraft Records and Documents listed
in Exhibit B hereto, together with such other documentation (including, without
limitation, original airworthiness directive compliance documents and other work
documents) regarding the condition, use, maintenance, or operation as Lessor may
reasonably request or require to substantiate the status of the Aircraft.

            (h) Corrections and Subsequent Corrections. To the extent that the
Aircraft or any Engine fails upon a Return Occasion to conform to any
requirement imposed by this Lease Lessor may, at its option, (i) continue the
Lease in effect in the manner provided for in Section 16(f) above with regard to
automatic extension until such time as such Aircraft is brought up to the
condition required by this Section 16, including Exhibit E, or (ii) accept the
return of such Aircraft and thereafter have any such nonconformance corrected,
at such time as Lessor may deem appropriate but not to commence later than
ninety (90) days following the return of such Aircraft, at commercial rates then
charged by the Person selected by Lessor to perform such correction. Lessee's
obligations to pay such Supplemental Rent shall survive the Expiration Date or
other termination of this Lease. Nothing set forth in this paragraph shall
constitute a limitation on Lessor's or Owner Participant's ability to recover
from Lessee any damages, expenses or losses pursuant to Sections 13 or 18 hereof
suffered as a result of Lessee's failure to effect the return of the Aircraft at
the time, in the place and in the condition as specified in this Section 16 and
Exhibit E hereto.

            (i) Functional Flight Check. Immediately prior to the expiration of
the Term, Lessor will be permitted to conduct a non-commercial functional flight
check flight of no more than two (2) hours duration in accordance with the
Manufacturer's functional flight check procedures at Lessee's expense to
demonstrate the airworthiness of the Aircraft and proper functioning of all
systems and components. A qualified pilot and up to five (5) other
representatives selected by Lessor may take part in such flight to verify
compliance of the Aircraft with the requirements of this Lease, provided, that
Lessor shall be responsible for the charges of such qualified pilot and
representatives. Lessee may combine the functional flight check provided in this
Section 16(i) with the delivery flight specified in Section 16(a) and such
functional flight check shall include the landing. Any discrepancy or


                                      -96-
   98
malfunction detected during any functional flight check (including a functional
flight check combined with a delivery flight) shall be corrected, at Lessee's
expense, and prior to the expiration of the Term. To the extent that any actions
to correct any such discrepancy or malfunction extend beyond the Term, the
provisions of the first sentence of Section 16(h) shall apply. All storage
expenses attributable to any Term extension pursuant to the preceding sentence
shall be payable by Lessee.

            (j) Export Certificate of Airworthiness. Lessee shall, at Lessee's
expense, take such action as Lessor may reasonably request to assist Lessor in
obtaining any required documents in relation to the export of the Aircraft from
the United States (including, without limitation, a valid and subsisting export
certificate of airworthiness with respect to the Aircraft and export license)
and in relation to the deregistration of the Aircraft.

            (k) Service Bulletin and Modification Kits. Lessee shall deliver to
Lessor, at no cost to Lessor, all service bulletin kits furnished without charge
by the manufacturer for installation on the Aircraft which have not been so
installed together with appropriate instructions for installation. In the event
such uninstalled kits were purchased or manufactured by Lessee, then Lessor
shall be advised of such kits by Lessee and have a right of first refusal to
purchase such kits at Lessee's cost for a period of ninety (90) days after
return.

            (l) Storage Upon Return. Upon any Return Occasion, Lessee shall, at
Lessor's request and at Lessee's risk and expense, in addition to other storage
referred to above, arrange for the parking, storage and insurance of the
Aircraft for a period not exceeding sixty (60) days at such reasonable location
as Lessor requests where Lessee has or can arrange for storage. Lessee shall pay
or cause to be paid all costs and expenses for such parking, storage and
insurance.

            (m) Resale/Release Cooperation. During the last twelve (12) months
of the Term, with reasonable notice and at reasonable times, Lessee will
cooperate, and cause any Permitted Sublessee to cooperate, in all reasonable
respects, with the efforts of Lessor to sell or lease the Aircraft after the end
of the Term, by permitting prospective purchasers or lessees, except to the
extent prohibited by applicable Law, to inspect the Aircraft and the records
relating thereto to the extent it does not


                                      -97-
   99
unreasonably interfere with the operation or maintenance of the Aircraft or the
conduct of Lessee's business.

            Section 17. Events of Default.

            Any one or more of the following occurrences or events shall
constitute an Event of Default (whether any such event shall be voluntary or
involuntary or come about or be effected by operation of Law or pursuant to or
in compliance with any judgment, decree or order of any court or any order, rule
or regulation of any other Governmental Entity):

            (a) Lessee shall fail to make (i) any payment of Basic Rent, Renewal
Rent or Stipulated Loss Value to Lessor within three (3) Business Days after the
date on which such payment is due, or (ii) any other payment of Supplemental
Rent due hereunder within ten Business Days after the date on which such payment
is due and Lessee has received written demand therefor by the party entitled
thereto; provided that any failure of Lessee to pay to Lessor or the Owner
Participant when due any Excepted Payments (as defined in the Indenture) shall
not constitute an Event of Default unless Lessor or Owner Participant delivers
notice to Lessee; or

            (b) Lessee shall fail to obtain and maintain in full force and
effect any insurance required under the provisions of Section 12 hereof or shall
operate the Aircraft outside of the scope or in violation of the terms of the
insurance or United States Government indemnity coverage required to be
maintained with respect to such Aircraft; or

            (c) Any representation or warranty made by Lessee herein or in the
Refunding Agreement or in any certificate furnished by Lessee in connection
herewith or therewith is or was incorrect at the time made in any material
respect and such incorrectness shall not have been cured within thirty (30) days
after the receipt by Lessee of a written notice from Lessor or the Indenture
Trustee advising Lessee of the existence of such incorrectness; or

            (d) Lessee shall fail to perform or observe any covenant, condition,
or agreement to be performed or observed by it pursuant to this Lease or the
Refunding Agreement, and such failure shall continue uncured for thirty (30)
days after written notice thereof is given by Lessor or Indenture Trustee to
Lessee; provided, however,


                                      -98-
   100
that if Lessee shall have undertaken to cure any such failure which arises under
the first or second sentence of Section 6(c) or Section 6(d), as such provisions
of Section 6 relate to maintenance, service, repair or overhaul, or Section 9,
and notwithstanding the diligence of Lessee in attempting to cure such failure,
such failure is not cured within said thirty (30) day period but is curable with
future due diligence, there shall exist no Event of Default under this Section
17 so long as Lessee is proceeding with due diligence to cure such failure and
such failure is remedied not later than one hundred eighty (180) days after
receipt by Lessee of such written notice; or

            (e) Lessee consents to the appointment of a custodian, receiver,
trustee or liquidator of itself or all or any material part of Lessee's property
or Lessee's consolidated property, or Lessee admits in writing its inability to,
or is unable to, or does not, pay its debts generally as they come due, or makes
a general assignment for the benefit of creditors, or Lessee files a voluntary
petition in bankruptcy or a voluntary petition seeking reorganization in a
proceeding under any bankruptcy or insolvency Laws (as now or hereafter in
effect), or an answer admitting the material allegations of a petition filed
against Lessee in any such proceeding, or Lessee by voluntary petition, answer
or consent seeks relief under the provisions of any other bankruptcy, insolvency
or other similar Law providing for the reorganization or winding-up of
corporations, or provides for an agreement, composition, extension or adjustment
with its creditors, or any corporate action (including, without limitation, any
board of directors or shareholder action) is taken by Lessee in furtherance of
any of the foregoing, whether or not the same is fully effected or accomplished;
or

            (f) An order, judgment or decree is entered by any court appointing,
without the consent of Lessee, a custodian, receiver, trustee or liquidator of
Lessee, or of all or any material part of Lessee's property, or Lessee's
consolidated property, or all or any material part of Lessee's property or
Lessee's consolidated property is sequestered, and any such order, judgment or
decree of appointment or sequestration remains in effect, undismissed, unstayed
or unvacated for a period of ninety (90) days after the date of entry thereof or
at any time an order for relief is granted; or

            (g) An involuntary petition against Lessee in a proceeding under the
Federal bankruptcy laws or other


                                      -99-
   101
insolvency Laws (as now or hereafter in effect) is filed and is not withdrawn or
dismissed within ninety (90) days thereafter or at any time an order for relief
is granted in such proceeding, or if, under the provisions of any Law providing
for reorganization or winding-up of corporations which may apply to Lessee, any
court of competent jurisdiction assumes jurisdiction over, or custody or control
of, Lessee or of all or any material part of Lessee's property, or Lessee's
consolidated property and such jurisdiction, custody or control remains in
effect, unrelinquished, unstayed or unterminated for a period of ninety (90)
days or at any time an order for relief is granted in such proceeding; or

            (h) Lessee's cessation of business as a commercial passenger
Certificated Air Carrier or, except in either case in connection with a labor
dispute, announcement thereof or Lessee's suspension of its business as a
commercial passenger Certificated Air Carrier, or for any reason the
preponderant business activity of Lessee shall cease to be that of a commercial
passenger Certificated Air Carrier; or

            (i) Lessee's loss or suspension of its United States air carrier
license or certificate under Part 121 of the Federal Aviation Regulations or
certificate under Section 41102(a) of the Federal Aviation Act.

            Section 18. 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 by written notice to Lessee this Lease to be in default, provided,
however, that this Lease shall be deemed to be declared in default automatically
without the necessity of such written declaration upon the occurrence of any
Event of Default described in paragraph (e), (f) or (g) of Section 17 hereof;
and at any time thereafter, so long as any outstanding Event of Default shall
not have been remedied, Lessor may do one or more of the following with respect
to all or any part of the Airframe and any or all of the Engines as Lessor in
its sole discretion shall elect, to the extent permitted by, and subject to
compliance with any mandatory requirements of, applicable Law then in effect:

            (a) Demand that Lessee, and Lessee shall upon the written demand of
Lessor and at Lessee's cost and expense, immediately return, and the Lessee
hereby agrees that it


                                      -100-
   102
shall return promptly all or such part of, the Aircraft to Lessor in the manner
specified in such notice, in which event such return shall not be delayed for
the purposes of complying with the return conditions specified in Section 16 and
Exhibit E hereof (none of which conditions shall be deemed to affect Lessor's
possession of the Aircraft) or delayed for any other reason; provided, however,
that Lessee shall remain and be liable to Lessor for amounts provided for herein
or other damages resulting from the Aircraft or any Engine not being in the
condition required by Section 16 and Exhibit E. Notwithstanding the foregoing,
at Lessor's option, Lessee shall be required thereafter to take such actions as
would be required by the provisions of this Lease if such Aircraft were being
returned at the end of the Term hereof with respect to such Aircraft. In
addition, Lessor or Lessor's agent, at its option and to the extent permitted by
applicable Law, may but shall not be obligated to enter upon the premises where
all or any part of the Aircraft, Airframe and/or Engines are located to take
immediate possession of and, at Lessor's option, remove the same (and/or any
engine which is not an Engine but which is installed on the Airframe, subject to
the rights of the owner, lessor or secured party thereof) by summary proceedings
or otherwise, all without liability accruing to Lessor or Lessor's agent for or
by reason of such entry or taking of possession or removal whether for the
restoration of damage to property, or otherwise, caused by such entry or taking,
except direct damages to the extent caused by Lessor's gross negligence or
willful misconduct.

            (b) With or without taking possession thereof, sell or cause to be
sold, the Aircraft, Airframe or Engine or any part thereof, or Lessor's interest
therein, at private or public sale, as Lessor in its sole discretion may
determine, or otherwise dispose of, hold, use, operate, or lease to others, or
keep idle the Aircraft, Airframe or Engine, as Lessor in its sole discretion may
determine, all free and clear of any rights of Lessee or any Permitted Sublessee
and except as hereinafter set forth in this Section 18. Lessor may be the
purchaser at any such sale.

            (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)
above, Lessor, by written notice to Lessee specifying a payment date which shall
be a Stipulated Loss Value Date may demand that Lessee pay to Lessor, and Lessee
shall pay to Lessor, on the Stipulated Loss Value Date specified in such notice,
as liquidated damages for loss of bargain and not as a penalty

   103
(in lieu of the Basic Rent or Renewal Rent, as the case may be, due for the
period commencing after the Stipulated Loss Value Date specified for payment in
such notice), any unpaid Rent for the Aircraft to and including the Stipulated
Loss Value Date specified in such notice, plus whichever of the following
amounts as Lessor may specify, in its sole and absolute discretion, in such
notice: (i) an amount equal to the excess, if any, of the sum of the Stipulated
Loss Value for the Aircraft, Airframe or Engine computed as of the date
specified in such notice plus, if such date is a Basic Rent Payment Date or a
Renewal Rent Payment Date, an amount equal to the Basic Rent or Renewal Rent, as
the case may be, due on such date, over the fair market sale value of the
Aircraft, Airframe or Engine as of the date specified in such notice or (ii) an
amount equal to the excess, if any, of the sum of the Stipulated Loss Value for
the Aircraft, Airframe or Engine computed as of the date specified in such
notice plus, if such date is a Basic Rent Payment Date or a Renewal Rent Payment
Date, an amount equal to the Basic Rent or Renewal Rent, as the case may be, due
on such date, over the fair market rental value of the Aircraft for the
remainder of the Term as of the date specified in such notice.

            (d) In the event Lessor, pursuant to paragraph (b) above, shall have
sold the Aircraft, Airframe or Engine or its interest therein, Lessor, in lieu
of exercising its rights under paragraph (c) above, may, if it shall so elect,
demand that Lessee pay Lessor, and Lessee shall pay to Lessor on such demand, as
liquidated damages for loss of bargain and not as a penalty (in lieu of the
Basic Rent or Renewal Rent, as the case may be, due for the period commencing
after the Stipulated Loss Value Date immediately prior to the date such sale
occurs), any unpaid Rent due to and including the date of sale, plus the amount
by which the Stipulated Loss Value of such Aircraft, Airframe or Engine,
computed as of such Stipulated Loss Value Date, exceeds the net proceeds of such
sale (after deducting all costs of such sale).

            (e) In lieu of exercising its rights under paragraph (b), (c) or (d)
above, by notice to Lessee, Lessor may require Lessee to pay, on the next
Stipulated Loss Value Date, to Lessor, and Lessee hereby agrees that it will so
pay to Lessor, as liquidated damages for loss of a bargain and not as a penalty
(in lieu of the Basic Rent or Renewal Rent, as the case may be, payable in
advance for the period on and after the Stipulated Loss Value Date), any unpaid
Basic Rent or Renewal Rent, as the case may be, for such


                                      -102-
   104
Aircraft due and unpaid for any period prior to and including, and any Basic
Rent or Renewal Rent payable on, the Stipulated Loss Value Date, plus, an amount
equal to the Stipulated Loss Value for the Aircraft computed as of such
Stipulated Loss Value Date; and upon such payment of liquidated damages and the
payment of all other Rent then due hereunder and the discharge of the Lien of
the Indenture pursuant to Section 10.01 thereof, Lessor shall, at Lessee's
expense, transfer, without recourse or warranty (except as to the absence of
Lessor's Liens and the Lien of the Indenture), all right, title and interest of
Lessor in and to the Aircraft to Lessee or as it may direct and Lessor shall, at
Lessee's expense, execute and deliver such documents evidencing such transfer
and take such further action as Lessee shall reasonably request.

            (f) In the event that Lessor, pursuant to paragraph (b) above, shall
have relet the Aircraft, Airframe or Engine under a long term lease, Lessor, in
lieu of exercising its rights under paragraph (c) above with respect to such
Aircraft, Airframe or Engine, may, if it shall so elect, demand that Lessee pay
Lessor, and Lessee shall pay Lessor on such demand, as liquidated damages for
loss of bargain and not as a penalty (in lieu of the Basic Rent or Renewal Rent,
as the case may be, for such Aircraft due after the time of reletting) any
unpaid Rent for such Aircraft due up to the date of reletting, plus the amount,
if any, by which the aggregate Basic Rent or Renewal Rent, as the case may be,
for such Aircraft which would otherwise have become due over the Basic Term or
Renewal Term, as the case may be, discounted periodically (equal to installment
frequency) to present worth as of the date of reletting at the rate of 8.50% per
annum, exceeds the aggregate basic rental payments to become due under the
reletting from the date of such reletting to the date upon which the Term for
such Aircraft, Airframe or Engine would have expired but for Lessee's default,
discounted periodically (equal to installment frequency) to present worth as of
the date of the reletting at the rate of 8.50% per annum.

            (g) Cancel, rescind and/or terminate this Lease by written notice to
Lessee which cancellation, rescission and/or termination shall be effective upon
dispatch, whereupon Lessee's right to possess and use the Aircraft, Airframe or
Engine shall immediately cease, however, Lessee shall be and remain liable for
damages and losses suffered by Lessor and all other amounts payable by Lessee
hereunder.



                                      -103-
   105
            (h) Lessor may exercise any other right or remedy which may be
available to it under applicable laws, or may proceed by appropriate court
action or actions, either at law or in equity, to enforce any other remedy or
right Lessor may have hereunder, under the other Operative Documents, at law or
in equity, including, without limitation, proceed by court order to enforce
performance by Lessee of the applicable covenants of this Lease or to recover
damages for the breach thereof.

            In addition to the foregoing, Lessee shall be liable (without
duplication of the remedies above and of Lessee's obligations under Section 10
and Section 13 hereof and subject to the exclusions set forth therein) for any
and all unpaid Rent before, during or after the exercise of any of the above
mentioned remedies (including without limitation interest on unpaid amounts with
respect to all amounts not paid when due, including, without limitation, any
amounts payable pursuant to the foregoing provisions of this Section 18), and,
except as specified above, until satisfaction of all of Lessee's obligations to
Lessor hereunder and for all legal fees and other costs and expenses incurred by
any Indemnitee by reason of the occurrence of any Event of Default or the
exercise of an Indemnitee's remedies with respect thereto, including all costs
and expenses incurred in connection with the return of the Aircraft in
accordance with the terms of Section 16 and Exhibit E hereof or in placing the
Aircraft, Airframe or Engine in the condition and with airworthiness
certification as required by such Section and such Exhibit and costs and
expenses related to the Lease, the Refunding Agreement, the Indenture, the Pass
Through Trust Agreements, the Intercreditor Agreement or each Liquidity
Facility. All liquidated damages payable pursuant to the foregoing shall bear
interest, which shall be payable on the date the payment of such liquidated
damages is due at a rate equal to the Interest Rate from and including the date
due to and excluding the date actually paid.

            In effecting any repossession, Lessor, its representatives and
agents, to the extent permitted by applicable Law, (i) shall have the right to
enter upon any premises where it reasonably believes the Aircraft, the Airframe,
an Engine or Part to be located, (ii) shall not be liable, in conversion or
otherwise, for the taking of any personal property of Lessee which is in or
attached to the Aircraft, the Airframe, an Engine or Part which is repossessed,
(iii) shall not be liable or responsible, in any manner, for any damage or
injury to any of Lessee's


                                      -104-
   106
property in repossessing and holding the Aircraft, the Airframe, an Engine or
Part except for direct damages caused by Lessor's gross negligence or willful
misconduct and (iv) shall have the right to maintain possession of and dispose
of the Aircraft, the Airframe, an Engine or Part on any premises owned by Lessee
or under Lessee's control.

            If requested by Lessor, Lessee shall, at its sole expense, assemble
and make the Aircraft, the Airframe, an Engine or Part available at a place
designated by Lessor in accordance with Section 16 and Exhibit E hereof. Lessee
hereby agrees that, in the event of the return to or repossession by Lessor of
the Aircraft, the Airframe, an Engine or Part, or otherwise upon the occurrence
of an Event of Default, any rights in any warranty (express or implied), service
life policy, infringement indemnity, performance guaranty or the like heretofore
made available to Lessee or otherwise held by Lessee shall without further act,
notice or writing be deemed automatically cancelled and shall be enforceable
solely by and for the benefit of, and assigned to, Lessor. Lessee shall be
liable to Lessor (without duplication) for all expenses, disbursements, costs
and fees incurred in (i) repossessing, storing, preserving, shipping,
maintaining, repairing and refurbishing the Aircraft, the Airframe, an Engine or
Part to the condition required by Section 16 and Exhibit E hereof and (ii)
preparing the Aircraft, the Airframe, an Engine or Part for sale or lease,
advertising the sale or lease of the Aircraft, the Airframe, an Engine or Part
and selling or releasing the Aircraft, the Airframe, an Engine or Part. Lessor
is hereby authorized and instructed, at its option, to make expenditures which
Lessor considers advisable to repair and restore the Aircraft, the Airframe, an
Engine or Part to the condition required by Section 16 and Exhibit E hereof, all
at Lessee's sole expense.

            For the purpose of this Section 18, the "fair market rental value"
or the "fair market sales value" of the Aircraft, Airframe, an Engine or Part
shall be determined pursuant to the Appraisal Procedure.

            At any sale of the Aircraft, the Airframe, an Engine or Part
pursuant to this Section , Owner Participant may bid for and purchase such
property and Lessee agrees that the amounts paid therefor shall be used in the
computations contemplated herein and Lessee shall remain liable for any
deficiency.



                                      -105-
   107
            No remedy referred to in this Section is intended to be exclusive,
but, to the extent permitted by Law, 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, to the extent permitted by Law, 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 of such other remedies.
No waiver by Lessor of any Event of Default shall in any way be, or be construed
to be, a waiver of the same Event of Default in the future or any other prior or
future Event of Default. To the extent permitted by Law, Lessee hereby waives
any right it may have to require Lessor to mitigate damages in connection with
the remedies described in Sections 18(c), (d), (e) or (f) above.

            Lessee hereby irrevocably appoints Lessor as Lessee's
attorney-in-fact (which appointment is coupled with an interest) to execute all
documents deemed necessary to release, terminate and void Lessee's interest in
the Aircraft leased hereunder or otherwise to more effectively carry out
Lessor's rights and remedies and to file said documents for recordation with the
FAA, under the Uniform Commercial Code, and with any other appropriate
Governmental Entity, and otherwise act in Lessee's name and place with respect
to the Aircraft, provided that an Event of Default has occurred and is
continuing and this Lease has been declared or deemed to be in default.

            The provisions of this Section 18 shall continue in full force and
effect and survive the expiration or other termination of this Lease and are
expressly made for the benefit of and shall be enforceable by Lessor, Owner
Participant and, if the Lien of the Indenture has not been discharged, Indenture
Trustee.

            Section 19. Security for Obligations. In order to secure the
Equipment Notes, Lessor has created, by the Indenture, a security interest in
the Trust Indenture Estate, including, without limitation, this Lease and all
Rent and other sums payable hereunder, except as provided in the Indenture and
subject in each case to Liens permitted hereunder. The Indenture provides, among
other things for the assignment by Lessor to Indenture Trustee of its right,
title and interest in, to and under this Lease, to the extent set forth in the
Indenture, for the creation of a first-mortgage lien on and perfected security
interest in all of Lessor's right, title and interest in and to the Aircraft in
favor of Indenture Trustee. Lessee hereby


                                      -106-
   108
consents to such assignment and to the creation of such mortgage and security
interest and acknowledges receipt of copies of the Trust Agreement and the
Indenture, it being understood that such consent shall not affect any
requirement or the absence of any requirement for any consent under any other
circumstances. Until the Lien of the Indenture has been discharged, Lessee will
furnish to Indenture Trustee counterparts of all notices and other writings of
any kind required to be delivered hereunder by Lessee to Lessor. Until the Lien
of the Indenture has been discharged, (a) Lessee shall make all payments of
Rent, Stipulated Loss Value and all other amounts payable hereunder (other than
Excepted Payments) to or as directed by Indenture Trustee as provided in
Sections 4(c) and 4(d), and (b) Indenture Trustee shall be entitled to exercise
the rights of Lessor (but not Owner Participant) (other than Expected Rights)
herein as and to the extent provided herein or in the Indenture and any express
reference to Indenture Trustee in any Section of this Lease shall not give rise
to any implication that Indenture Trustee may not exercise the rights of Lessor
in any other Section of this Lease as and to the extent provided in the
Indenture.

            The provisions of this Lease and the Refunding Agreement which
require or permit action by, the payment of monies to, the consent or approval
of, the furnishing of any instrument or information to, or the performance of
any other obligation to, Indenture Trustee, shall not be effective, and the
Sections hereof containing such provisions shall be read as though there were no
such requirements or provisions and all moneys otherwise payable to Indenture
Trustee hereunder shall be paid to Lessor, after Lessee shall have received from
Indenture Trustee notice of discharge of the Lien of the Indenture.

            Any payment or performance by Lessee to or as directed by Indenture
Trustee shall constitute payment or performance of such obligation to Lessor by
Lessee under this Lease.

            Any payment or performance of an obligation of Lessee under this
Lease by a Permitted Sublessee shall constitute payment or performance of such
obligation by Lessee.

            Section 20. Renewal Option. Lessee may renew this Lease as provided
in the following clause (i) and subject to the following clause (ii):



                                      -107-
   109
                  (i) Exercise of Renewal Option. Provided that this Lease has
         not been previously terminated and that no Default or Event of Default
         shall have occurred and be continuing at the time of the giving of
         irrevocable notice hereinafter referred to in this clause (i) or at the
         time of the commencement of the Renewal Term, Lessee, at its option,
         may renew this Lease for one Renewal Term consisting of a period equal
         to five years. The right to renew this Lease for such Renewal Term
         pursuant to this clause (i) shall be exercised upon irrevocable notice
         from Lessee received by Lessor of Lessee's election to so renew this
         Lease not less than twelve (12) months and not more than twenty-four
         (24) months prior to the last day of the Basic Term. The Renewal Rent
         for the Renewal Term shall be the "fair market rental value" of the
         Aircraft for such Renewal Term (the "renewal fair market rental value")
         as determined in accordance with the Appraisal Procedure. For purposes
         of this paragraph (i), the Appraisal Procedure shall be initiated by
         Lessee no earlier than nine (9) months prior to the end of the Basic
         Term. If Lessee shall fail to exercise its option to extend the term of
         this Lease for the Renewal Term in accordance with the provisions of
         this paragraph, all of Lessee's rights to extend the Term for such
         Renewal Term shall expire. Lessee shall pay all reasonable costs and
         expenses, including, without limitation, reasonable legal fees and
         expenses, incurred by Lessor, Owner Participant and the Indenture
         Trustee in connection with the exercise of such option.

                  (ii) Provisions Applicable During Renewal Term. All provisions
         of this Lease, including, without limitation, as to Rent and Stipulated
         Loss Value (which shall be, with appropriate adjustments, in no event
         less than the greater of 120% of the "fair market sales value" of the
         Aircraft as of the first day of the Renewal Term as determined pursuant
         to the Appraisal Procedure or the amount set forth on Exhibit A as of
         the end of the Basic Term), shall remain in effect and be applicable
         during such Renewal Term, except that Lessee shall pay to the Lessor,
         semi-annually in arrears as Renewal Rent on each Renewal Rent Payment
         Date, the amount for such Renewal Term as determined in accordance with
         clause (i) of this Section 20.



                                      -108-
   110
            Section 21. Miscellaneous.

            (a) Severability, Amendment, and Construction. Any provision of this
Lease which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction. To the extent
permitted by Law, each of Lessor and Lessee hereby waives any provision of Law
which renders any provision hereof prohibited or unenforceable in any respect.
No term or provision of this Lease may be changed, waived, discharged, or
terminated orally, but only by an instrument in writing expressed to be a
supplement or amendment to, or waiver or termination of this Lease signed by an
officer of the party against which the enforcement of the change, waiver,
discharge, or termination is sought. This Lease shall constitute an agreement of
lease, and nothing herein shall be construed as conveying to Lessee any right,
title, or interest in the Aircraft or any Engine or Part except as a lessee
only. Without limiting the foregoing, the parties hereto agree to treat this
Agreement as a lease for United States federal income tax purposes and Lessee
will not file a tax return which is inconsistent with the foregoing and nothing
contained herein shall be construed as an election by Lessor to treat Lessee as
having acquired the Aircraft for the purpose of the investment credit allowed by
Section 38 of the 1954 Code or any similar or successor statute. The headings in
this Lease are for convenience of reference only and shall not define or limit
any of the terms or provisions hereof.

            (b) GOVERNING LAW. THIS LEASE HAS BEEN EXECUTED AND DELIVERED IN THE
STATE OF NEW YORK AND SHALL IN ALL RESPECTS BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE INTERNAL SUBSTANTIVE LAWS OF THE STATE OF NEW YORK,
INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY, AND PERFORMANCE WITHOUT REGARD
TO PROVISIONS GOVERNING CONFLICTS OF LAW WHICH MIGHT LEAD TO THE APPLICATION OF
THE LAWS OF ANOTHER JURISDICTION.

            (c) Notices. All notices and instructions between Lessor and Lessee
required or permitted under the terms and provisions hereof shall be in writing
and shall be sent to Lessor or Lessee at their respective addresses set forth in
Exhibit C hereto (or such other addresses as the parties may designate from time
to time in writing). All


                                      -109-
   111
notices, reports or other documents provided to Lessor or Lessee shall be
provided concurrently to Indenture Trustee (until such time as the Lien of the
Indenture is discharged) and to Owner Participant, at such address as Owner
Participant and Indenture Trustee, respectively, may designate from time to
time. All notices and instructions hereunder shall become effective when
received.

            (d) Lessor's Right to Perform for Lessee. If Lessee fails to make
any payment of Rent required to be made by it hereunder or fails to perform or
comply with any covenant, agreement, or obligation contained herein, Lessor
shall have the right but not the obligation to make such payment or conform or
comply with such agreement, covenant, or obligation, and the amount of such
payment and the amount of the reasonable expenses of Lessor incurred in
connection with such payment or the performance thereof or compliance therewith,
together with interest thereon at the Interest Rate, shall be payable by Lessee
to Lessor (as Supplemental Rent) upon demand. The taking of any such action by
Lessor pursuant to this Section 21(d) shall not constitute a waiver or release
of any obligation of Lessee under this Lease, nor a waiver of any Event of
Default which may arise out of Lessee's nonperformance of such obligation, nor
an election or waiver by Lessor or any remedy or right available to Lessor under
or in relation to this Lease.

            (e) Counterparts. To the extent, if any, that this Lease constitutes
chattel paper (as such term is defined in the Uniform Commercial Code as in
effect in any applicable jurisdiction), no security interest in this Lease may
be created through the transfer or possession of any counterpart other than the
original counterpart, which shall be identified as the counterpart containing
the receipt therefor executed by or on behalf of Indenture Trustee on the
signature page thereof. Subject to the preceding sentence, this Lease may be
executed in two or more counterparts, each of which shall be deemed an original,
but all of which together shall constitute one and the same instrument.

            (f) Quiet Enjoyment. Lessor covenants that, so long as no Event of
Default shall have occurred and be continuing and this Lease has not been
declared or deemed to be in default, Lessor shall not take or cause to be taken
any action to interfere with the right of Lessee to the possession, use,
operation and quiet enjoyment of and other rights with respect to the Aircraft
hereunder, and all rents, revenues, profits and income therefrom, in accordance


                                      -110-
   112
with the terms of this Lease without interference from Lessor or any Person
lawfully claiming by or through it, provided that Lessor and Owner Participant
shall not be liable for any such interference by Indenture Trustee, Pass Through
Trustee, Note Holder or any other Person lawfully claiming by or through them,
and provided further, that the foregoing shall not be deemed to have modified
the obligations of Lessee pursuant to Section 4(d) hereof, which obligations
remain absolute and unconditional.

            (g) Brokers. Lessee and Lessor agree that, except as provided in the
Refunding Agreement, there has been no third party as agent involved in this
Lease and each indemnifies the other from liability for fees, commissions, or
other claims made upon the other due to any such claim.

            (h) Investment of Funds. Any monies which are held by Lessor or
Indenture Trustee and are payable to Lessee shall, unless a Default or an Event
of Default shall have occurred and be continuing, be invested as provided below
until paid to Lessee or applied by Lessor or Indenture Trustee to the extent
provided herein. Until paid to Lessee or applied as provided herein or in the
Indenture such monies shall be invested by Lessor or Indenture Trustee from time
to time at the expense of Lessee in Specified Investments, as directed by Lessee
in accordance with the provisions of Section 3.07 of the Indenture if the Lien
of the Indenture shall not have been discharged and thereafter as provided
below. There shall be promptly (but not more frequently than monthly) remitted
to Lessee any gain (including interest received) realized as the result of any
such investment (net of any fees, commissions and other reasonable expenses, if
any, incurred in connection with such investment) unless a Default or an Event
of Default shall have occurred and be continuing. Lessee will promptly pay to
Lessor or Indenture Trustee, as the case may be, and hold Lessor or Indenture
Trustee harmless from, on demand, the amount of any loss realized as the result
of any such investment (together with any Taxes, fees, commission and other
reasonable expenses, if any, incurred in connection with such investment).

            (i) Entire Agreement; Amendment. This Lease (including the Exhibits
hereto), any related letter agreements and the other Operative Documents, the
Financing Documents and the Purchase Documents (including the Exhibits thereto)
and all closing documents delivered in connection with any of the foregoing
embody the entire agreement and understanding among the parties hereto with
respect to the


                                      -111-
   113
subject matter hereof. This Lease may be changed, waived, discharged, amended,
revised or terminated only by an instrument in writing signed by the party
against which enforcement is sought.

            (j) Expenses. Without limiting Section 13 or 18, Lessee agrees
within fifteen (15) days after demand to pay or reimburse Lessor for all
reasonable out-of-pocket costs and expenses (including, without limitation,
legal and other professional fees and expenses) incurred or payable by Lessor in
connection with or related to (i) the fees and expenses of Owner Trustee and
Indenture Trustee, (ii) to the extent requested by or relating to acts or
omissions of Lessee or as otherwise provided herein or to give effect to the
provisions hereof, or the other Operative Documents, the Financing Documents or
the Purchase Documents, any future amendments, supplements or other
modifications hereof or thereof, or waivers or consents hereunder or thereunder,
and (iii) any Default or Event of Default or the enforcement of any of Lessor's
rights, remedies or privileges hereunder or at law or in equity, but not
Lessor's legal fees and expenses in connection with the negotiation and
execution of this Lease or the Financing Documents.

            (k) Federal Bankruptcy Code. In the event Section 1110 of Title 11
of the United States Code is amended, or if it is repealed and another statute
is enacted in lieu thereof, Lessor and Lessee agree to amend this Lease and take
such other action not inconsistent with this Lease as Lessor reasonably deems
necessary so as to afford to Lessor the rights and benefits as such amended or
substituted statute confers upon owners and lessors of aircraft similarly
situated to Lessor.

            (l) U.S. Registration Number. At Lessee's request, Lessor shall use
its best efforts to have the Aircraft registered under the United States
Registration Number designated by Lessee.

            (m) Submission to Jurisdiction; Service of Process; Waiver of Forum
Non Conveniens; Waiver of Jury Trial. Each of Lessee and Lessor hereby
irrevocably agrees that any suit, action or proceeding related to this Lease or
any of the other Operative Documents to which it is a party or the subject
matter hereof or thereof or any of the transactions contemplated hereby and
thereby may be instituted in, and submits for itself and its property to the
non-exclusive jurisdiction of, (i) the courts of the State of New York in New
York County and (ii) the United


                                      -112-
   114
States District Court for the Southern District of New York. Each of Lessee and
Lessor represents and warrants that it is not currently entitled to, and agrees
that to the extent that Lessee or Lessor hereinafter may acquire, any immunity
(including, without limitation, sovereign immunity) from jurisdiction of any
court or from any legal process, it hereby, to the extent permitted by Law,
waives such immunity, and agrees not to assert, by way of motion, as a defense,
or otherwise, in any such suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of the above-named courts that it is
immune from any legal process (whether through service or notice, attachment
prior to judgment, attachment in aid of execution, execution or otherwise) with
respect to itself or its property, that the suit, action or proceeding is
brought in an inconvenient forum, that the venue of the suit, action or
proceeding is improper, or that this Lease or any of the other Operative
Documents or the subject matter hereof or thereof or any of the transactions
contemplated hereby and thereby may not be enforced in or by such courts. Each
of Lessee and Lessor hereby generally consents to service of process by
registered mail, return receipt requested, addressed to it at its address set
forth in Exhibit C, or at such other office of Lessee or Lessor as from time to
time may be designated by Lessee or Lessor (as applicable) in writing to Lessee
or Lessor (as applicable), Owner Participant and Indenture Trustee. Each of
Lessee and Lessor hereby agrees that its submission to jurisdiction and its
designation of service of process by mail set forth above is made for the
express benefit of Lessor, Lessee, Owner Participant, Indenture Trustee, each
Note Holder and their successors and assigns (as applicable). Final (after all
appeals) judgment (the enforcement of which has not been stayed) against either
Lessee or Lessor obtained in any suit originally brought in the court of the
State of New York in New York County or in the United States District of New
York shall be conclusive, and, to the extent permitted by applicable Law, may be
enforced in other jurisdictions by suit on the judgment, a certified or true
copy of which shall be conclusive evidence of the fact and of the amount of any
indebtedness or liability of Lessee therein described; provided that the
plaintiff at its option may bring suit, or institute other judicial proceedings,
against Lessee or Lessor, as the case may be, or any of their assets in the
courts of any country or place where such Person or such assets may be found.
EACH OF LESSEE AND LESSOR HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY AND
ALL RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING
OUT OF THE OPERATIVE DOCUMENTS OR ANY DEALINGS


                                      -113-
   115
BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THE TRANSACTIONS CONTEMPLATED
THEREBY OR THE LESSOR/LESSEE RELATIONSHIP BEING ESTABLISHED, including, without
limitation, contract claims, tort claims, breach of duty claims and other common
law and statutory claims. Lessor and Lessee represent and warrant that each has
reviewed this waiver with its legal counsel, and that each knowingly and
voluntarily waives its jury trial rights following consultation with such legal
counsel. THIS WAIVER IS IRREVOCABLE, AND THIS WAIVER SHALL APPLY TO ANY
SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THE OPERATIVE
DOCUMENTS. In the event of litigation, this Agreement may be filed as a written
consent to a trial by the court.

            (n) Limitation on Recourse. The parties hereto agree that all
statements, representations, covenants and agreements made by Lessor (when made
in its capacity as such and not in its individual capacity) contained in this
Agreement, unless expressly otherwise stated, are made and intended only for the
purpose of binding the Trust Estate and establishing the existence of rights and
remedies that can be exercised and enforced against the Trust Estate. Therefore,
no recourse shall be had with respect to anything contained in this Agreement
(except for any express provisions that Lessor is responsible for in its
individual capacity), against Lessor in its individual capacity or against any
institution or person that becomes a successor trustee or co-trustee or any
officer, director, trustee, servant or direct or indirect parent or controlling
Person or Persons of any of them; provided that (i) this Section 21(n) shall not
be construed to prohibit any action or proceeding against any party hereto for
its own willful misconduct or grossly negligent conduct for which it would
otherwise be liable and (ii) nothing contained in this Section 21(n) shall be
construed to limit the exercise and enforcement in accordance with the terms of
this Agreement or such other agreements of rights and remedies against the Trust
Estate. The foregoing provisions of this Section 21(n) shall survive the
termination of this Agreement and the other Operative Documents.

            (o) Successor Trustee. Lessee agrees that in the case of the
appointment of any successor Owner Trustee pursuant to the terms of the Trust
Agreement, such successor Owner Trustee shall, upon written notice by such
successor Owner Trustee, succeed to all the rights, powers and title of Lessor
hereunder and shall be deemed to be Lessor and the owner of the Aircraft for all
purposes hereof without the


                                      -114-
   116
necessity of any consent or approval by Lessee (subject to Section 14(d) of the
Refunding Agreement) and without in any way altering the terms of this Lease or
Lessee's obligations hereunder. One such appointment and designation of a
successor Owner Trustee shall not exhaust the right to appoint and designate
further successor Owner Trustees pursuant to the Trust Agreement, but such right
may be exercised repeatedly as long as this Lease shall be in effect.

            (p) Article 2-A of the UCC. The parties hereto agree that the
Original Head Lease, as amended and restated by this Amended and Restated
Aircraft Lease Agreement [GPA 1990 AWA-13] (and as otherwise extended, amended,
modified, renewed or supplemented), shall be governed by Article 2-A of the
Uniform Commercial Code of New York.


                                      -115-
   117
            IN WITNESS WHEREOF, Lessor and Lessee, each pursuant to due
authority, have each caused this Lease to be executed by its duly authorized
officer as of the day and year first above written.

                                             Lessor:
