     The Lessee covenants and agrees that, during the Term hereof:

     8.01. MAINTENANCE OF CORPORATE EXISTENCE. The Lessee will preserve and
maintain (a) its corporate existence, and (b) all of its rights, privileges

Section 7.02, the Lessee will promptly give to the Lessor a notice in writing of
any proceeding involving a claim in excess of $1,000,000 before any governmental

affect the Lessee's financial condition, affairs or operations.

     8.03. PAYMENT OF TAXES. The Lessee will pay or cause to be paid all taxes,
assessments and governmental charges or levies imposed upon it or upon its
income and profits, or upon any property belonging to it, prior to the date on

                                       8-1
<Page>

become a lien or charge upon the property of the Lessee, PROVIDED, HOWEVER, that
the Lessee shall not be required to pay any such tax, assessment, charge, levy
or claim the pavement of which is being contested in good faith and by
appropriate proceedings, but only so long as such proceedings do not involve any
danger of adverse impact on business interests of the Lessor or of the sale,
forfeiture or loss of an Aircraft or any Item or interest therein; PROVIDED
FURTHER, that the Lessee will pay or cause to be paid all such taxes,
assessments, charges, levies or claims forthwith upon the commencement of

hereunder at any time removed from any Item of Equipment shall remain the

time make such alterations and modifications in and additions to each Item as
the Lessee may deem desirable in the proper conduct of its business, PROVIDED
that no such alteration, modification or addition diminishes the value, utility,
condition or airworthiness of such Item below the value, utility, condition and
airworthiness thereof immediately prior to such alteration, modification or
addition, assuming such Item was then in the condition and airworthiness
required to be

                                       9-2
<Page>

maintained by the terms of this Lease, PROVIDED FURTHER, that the Lessee shall

incorporated or installed in or attached or added to any Item as the result of
any alteration, modification or addition made as contemplated in Section 9.03
hereof shall, without further act, vest in the Lessor and become subject to this
Lease; PROVIDED, HOWEVER, that so long as no Default or Event of Default shall

addition to, and not in replacement of or in substitution for, any Part
originally incorporated or installed in or attached to such Item at the time of
delivery thereof hereunder or any Part in replacement of, or substitution for,
any such original Part; (B) such Part is not required to be incorporated or
installed in or attached or added to such Item pursuant to the terms of Section
6.05 hereof or the first sentence of Section 9.03; and (C) such Part can be
removed from such Item without diminishing or impairing the value, utility

                                       9-3
<Page>

or airworthiness which such Item would have had at such time had such
alteration, modification or addition not occurred. Upon the removal by the
Lessee of any such Part as above provided, title thereto shall, without further
act, vest in the Lessee and such Part shall no longer be deemed a Part

                              GENERAL TAX INDEMNITY

     10.01. (a) INDEMNITY. Whether or not any of the transactions contemplated
hereby are consummated, the Lessee agrees to pay and, on written demand, to
indemnify, protect, save and hold Lessor harmless from all license and
registration fees, sales and use taxes, personal property taxes and any and all
other taxes, levies, imposts, duties, charges, assessments or withholdings of
any nature whatsoever together with any penalties, additions to tax, fines or
interest thereon (collectively, "Taxes") imposed against Lessor, Lessee or any
Item of Equipment, by any Federal, state or local government or taxing authority
in the United States, or by any taxing authority or governmental subdivision of
a foreign country or international organization, upon or with respect to any
Item of Equipment, or upon the purchase, ownership, delivery, leasing,
possession, use, operation, return or other disposition thereof, or upon the
rentals, receipts or earnings arising therefrom, or upon or with respect to this
Lease or related documents.

          (b) LIMITATION ON INDEMNITY. Notwithstanding the provisions of
     paragraph (a) of this Section 10.01, Lessee shall

                                      10-1
<Page>

have no obligation thereunder as to Taxes based on or measured by the net income
of Lessor imposed by the United States of America or by any state or local
taxing authorities, including any Taxes resulting from an amendment of the Code
enacted after March 1, 1988, or any Taxes imposed on Lessor by any state which
result from either Lessor's residency or Lessor's doing business in that state
which is business unrelated to any Item of Equipment; provided, however, Lessee
shall be liable for Taxes based on or measured by Lessor's net income if, but
only if, such taxes are taxes on Lessor's net income which would not have been
imposed but for the use or operation of any Item of Equipment within the
jurisdiction of such taxing authority by Lessee, at Lessee's direction, or with
Lessee's consent. Lessee shall not have any liability to indemnify Lessor for
any Taxes imposed by any taxing jurisdiction if the Taxes result from delivery,
use, storage, return or physical presence of any Item of Equipment after return
of the respective Item of Equipment to Lessor by Lessee under #16.01. If an
indemnification payment is made under Article 21 hereof, the same event giving
rise to such payment shall not also result in an indemnification payment under
this Article 10 for the taxes indemnified in Article 21.

     10.02. AFTER-TAX NATURE OF INDEMNITY. The Lessee further agrees that, with
respect to any payment or indemnity hereunder, such payment or indemnity shall
include any amount necessary to hold Lessor harmless on an after-tax basis from
all taxes required to be paid (or which would have been required to be paid by
Lessor with respect to such payment or indemnity had Lessor had

                                      10-2
<Page>

sufficient gross income within the meaning of Section 61 of the Code, and the
applicable state and local law, actually to pay tax at the highest marginal
rate) by Lessor with respect to such payment or indemnity under the laws of any
Federal, state or local government or taxing authority in the United States, or
under the laws of any taxing authority or governmental subdivision of a foreign
country or international organization; PROVIDED that, if Lessor realizes a tax
benefit by reason of such payment or indemnity (whether such tax benefit shall
be by means of a depreciation deduction or otherwise), Lessor shall pay the
Lessee an amount equal to the net value to Lessor of such tax benefit when, as,
if and to the extent realized (such payments not to exceed in the aggregate the
amount of the related indemnity paid by Lessee); but not before the Lessee shall
have made all payments or indemnities to Lessor required pursuant to this
Article 10; PROVIDED FURTHER, however, that if Lessor loses such tax benefit
subsequent to any payment to the Lessee with respect thereto, the Lessee shall
indemnify Lessor with respect to such loss pursuant to the provisions of this
Article 10. Lessor shall in good faith use reasonable diligence in filing its
tax returns and in dealing with taxing authorities to seek and claim any such
tax benefit.

     10.03. CONTEST. If written claim is made against Lessor for any Taxes
referred to in this Article 10, Lessor shall promptly notify the Lessee. If
reasonably requested by the Lessee in writing within 30 days after such
notification, Lessor shall upon receipt of indemnity satisfactory to it and at
the expense of the Lessee (including, without limitation, all costs, expenses,
losses, legal and accountants' fees and disbursements, penalties

                                      10-3
<Page>

and interest) in good faith contest the validity, applicability or amount of
such Taxes by either (i) resisting payment thereof if practicable, or (ii) if
payment is made, using reasonable efforts to obtain a refund thereof in
appropriate administrative and judicial proceedings; PROVIDED, HOWEVER, that
the Lessor shall not be required to take any action to contest a claim unless
Lessee provides with such written request an opinion of independent counsel,
satisfactory both as to counsel and substance, to the effect that there is a
meritorious basis for such contest. If Lessor determines to pay such Taxes and
seek a refund, Lessee will either pay such Taxes on Lessor's behalf or will
promptly indemnify Lessor for such Taxes pursuant to Sections 10.1 and 10.2. If
Lessor shall obtain a refund of all or any part of such Taxes paid by the
Lessee, Lessor shall pay the Lessee the amount of such refund; PROVIDED that
such amount shall not be payable before such time as the Lessee shall have made
all payments of indemnities to Lessor then due under this Article 10. If in
addition to such refund Lessor shall receive an amount representing interest on
the amount of such refund, the Lessee shall be paid that proportion of such
interest which is fairly attributable to the Taxes paid by the Lessee prior to
the receipt of such refund. In case any report or return is required to be made
with respect to any obligation of the Lessee under this Article 10 or arising
out of this Article 10 the Lessee will promptly notify Lessor of such
requirement and will inform Lessor whether Lessee (i) will file such report or
return in such manner as will show the ownership in Lessor of each Item of
Equipment and send a copy of such report or

                                      10-4
<Page>

return to the Lessor or (ii) will make such report or return for filing by
Lessor in such manner as shall be satisfactory to the Lessor. In the event of a
contest of any Taxes hereunder, the Lessor shall apprise the Lessee of all
material developments with respect to such contest, shall forward copies of all
material submissions made in such contest, shall consider in good faith any
request concerning the conduct of any such contest and without waiving its right
to be indemnified hereunder with respect to such claim shall not settle or
concede any such contest without the written consent of the Lessee.

                DAMAGE, DESTRUCTION, REQUISITION OR CONDEMNATION

     11.01. EVENT OF LOSS WITH RESPECT TO AN AIRFRAME OR AN AIRFRAME AND THE
ENGINES INSTALLED THEREON. Upon the occurrence of an Event of Loss with respect
to an Airframe or to an Airframe and the Engines then installed on such
Airframe, the Lessee shall forthwith (and in any event within 10 days after such
occurrence) give the Lessor written notice of such Event of Loss. The Lessee
shall pay or cause to be paid to the Lessor in immediately available funds on
the earlier to occur of (i) five days after the date Lessee receives insurance
proceeds from such Event of Loss or (ii) the next immediately succeeding date on
which a Basic Rent installment is to he paid (A) then due and unpaid Rent
(prorated to the date of payment) in respect of such Aircraft to and including
such date; and (B) an amount equal to the Stipulated Loss Value in respect of
such Aircraft determined as of the date of such Event of Loss and (C) interest
at the Incentive Rate on the unpaid balance of (A) and (B) above from the due
date until paid in full, PROVIDED, HOWEVER, that payment of the Stipulated Loss
Value shall be made within ten days if the Event of Loss occurs after the
payment by the Lessee of the final Basic Rent installment and before termination
of the storage period provided for in Section 16.06 hereof. At such time as the
Lessor has received the sum of (A), (B) and (C) above, the obligation of the
Lessee to pay all Basic rent hereunder with respect to such

                                      11-1
<Page>

Aircraft shall terminate, and the Lessor stall transfer to the Lessee all the
Lessor's right, title, and interest, as-is, where-is, without recourse or
warranty, express or implied, in and to (1) such Airframe and Engines, (2) all
claims for damage to such Items, if any, against third persons arising from the
Event of Loss (unless any insurance carrier requires that such claims be
assigned to it), and (3) all rights to any insurance claims under all insurance
maintained by the Lessee hereunder except liability insurance, without
representation, recourse or warranty of any kind whatsoever.

     11.02. WITH RESPECT TO AN ENGINE. Upon the occurrence of an Event of Loss
with respect to an Engine not then installed on an Airframe, or an Event of Loss
with respect to an Engine installed on an Airframe not involving an Event of
Loss with respect to the Airframe, the Lessee shall give the Lessor prompt
written notice thereof and the Lessee shall replace such Engine as soon as
practicable after the occurrence of such Event of Loss by duly conveying to the
Lessor as a replacement for said Engine, title to another engine of the same
manufacturer and of the same or an improved model and suitable for installation
and use on the Airframe, which engine shall be free and clear of all Liens, and
shall have a value and utility at least equal to, and he in as good an operating
condition as, the Engine with respect to which such Event of Loss occurred,
assuming such replaced Engine was of the value and utility and in the condition
and repair as required by the terms hereof immediately prior to the occurrence
of such

                                      11-2
<Page>

Event of Loss. Such replacement engine, after approval and acceptance by the
Lessor, shall be deemed an Engine as defined herein, for all purposes hereunder.
The Lessee agrees to take such action as the Lessor may reasonably request to
ensure that any such replacement Engine shall be duly and properly titled in the
name of Lessor and leased hereunder to the same extent as any Engine replaced
thereby. Prior to or at the time of any such conveyance, the Lessee, at its own
expense, will promptly (i) furnish the Lessor with a warranty bill of sale, in
form and substance satisfactory to the Lessor, with respect to such replacement
Engine, (ii) cause a supplement hereto, in form and substance satisfactory to
the Lessor, subjecting such replacement Engine to this Lease, to be duly
executed by the Lessee, and recorded pursuant to the Federal Aviation Act, and
(iii) furnish the Lessor with such evidence of title to such replacement Engine
and of compliance with the insurance provisions of Article 12 hereof with
respect to such replacement Engine as the Lessor may reasonably request. Upon
full compliance with this Section 11.02, the Lessor shall transfer to the Lessee
all the Lessor's right, title and interest, as-is, where-is, without recourse or
warranty, express or implied, in and to (1) the Engine with respect to which
such Event of Loss occurred, (2) all claims for damage to such Engine, if any,
against third persons arising from the Event of Loss (unless any insurance
carrier requires that such claims be assigned to it), and (3) all rights to any
insurance claims under all insurance maintained by the Lessee hereunder except
liability insurance. No Event of Loss with respect to such Engine under the

                                      11-3
<Page>

circumstances contemplated by the terms of this Section 11.02 shall result in
any reduction in Rent or in the Lessee's obligation to pay Basic Rent hereunder.
The Lessee agrees that it shall at all times during the Term of this Lease
maintain the Engines or other engines of the same or improved model and suitable
for installation and use on the Airframes as the Engines on the Aircraft leased
hereunder. The Lessee agrees that it will indemnify the Lessor, pursuant to
Article 21 hereof, for any loss of tax benefits resulting from such Event of
Loss with respect to an Engine.

     11.03. APPLICATION OF PAYMENTS FROM GOVERNMENTAL AUTHORITIES FOR
REQUISITION OF TITLE. Any payments (other than insurance proceeds the
application of which is provided for in Article 12 hereof) received at any time
by the Lessor or the Lessee from any Governmental authority or other entity with
respect to an Event of Loss resulting from the condemnation, confiscation, theft
or seizure of, or requisition of title to or use of an Aircraft, Airframe or
Engines, will be applied as follows:

          (A) If such payments are received with respect to an Event of Loss
     relating to an Airframe and installed Engines, only so much of such
     payments as shall not exceed the amounts due under Section 11.01(A), (B)
     and (C) shall be applied in reduction of the Lessee's obligation to pay
     such amounts, if not already paid by the Lessee, or if already paid by the
     Lessee, shall be applied to reimburse the Lessee for its

                                      11-4
<Page>

     payment of such amounts, and the balance, if any, of such payments
     remaining thereafter will he paid over to or retained by the Lessor; and

          (B) If such payments are received with respect to an Engine under the
     circumstances described in section 11.02, all such payments shall be paid
     over to the Lessee, at such time as the Lessee shall have replaced such
     Engine in accordance with the provisions of said Section 11.02.

                                    INSURANCE

     12.01. PUBLIC LIABILITY AND PROPERTY DAMAGE LIABILITY INSURANCE. The Lessee
will carry, at its own expense, third party aircraft liability insurance,
passenger legal liability insurance and property damage liability insurance
during the Term hereof in an amount not less than $75,000,000 for any one
accident, or series of accidents arising out of any one event, with respect to
each Aircraft. Any such liability insurance policy shall not contain a provision
for deductible or self-insurance amounts. In any event all such policies shall
be (A) in amounts which are not less than the public liability and property
damage insurance applicable to similar aircraft and engines which may at any
time during the Term hereof comprise the Lessee's fleet on which the Lessee
carries insurance; and (B) maintained in effect with insurers of recognized
reputation and responsibility, reasonably satisfactory to the Lessor. Any
policies of insurance carried in accordance with this Section 12.01 and any
policies taken out in substitution or replacement of any of such policies: (1)
shall name the Lessor as owner and as additional insured; (2) shall provide that
in respect of the interest of the Lessor such policies of insurance shall not be
invalidated by any action or inaction of the Lessee and shall insure Lessor

                                      12-1
<Page>

regardless of any breach or violation of any warranty, declarations or
conditions contained in such policies by the Lessee; and (3) shall provide that
if the insurers cancel such insurance for any reason whatever, or the same is
allowed to lapse for nonpayment of premium, or if there is any material change
in policy terms or conditions, such cancellation, lapse or change shall not be
effective for thirty (30) days after receipt by the Lessor of written notice by
such insurers to the Lessor of such cancellation, lapse or change. Each
liability policy (i) shall be primary without right of contribution from any
insurance which is carried by the Lessor, (ii) shall expressly provide that all
of the provisions thereof, except the limits of liability, shall operate in the
same manner as if there were a separate policy covering each insured, and (iii)
shall waive any rights of set-off, counterclaim or other deduction against each
named insured. The Lessee shall arrange for evidence of appropriate coverage as
to each Aircraft and as to the satisfaction of the requirements set forth above
in this Section 12.01 to be furnished to the Lessor on or before the Delivery
Date for each Aircraft by Lessee's insurance broker.

     12.02. INSURANCE AGAINST LOSS OR DAMAGE TO THE AIRCRAFT. The Lessee shall
maintain in effect, at its own expense, with insurers of recognized reputation
and responsibility reasonably satisfactory to the Lessor: (A) all-risk ground
and

                                      12-2
<Page>

flight aircraft hull insurance covering the Aircraft; (B) fire, transit and
extended coverage with respect to any Engines or Parts while removed from an
Aircraft; (C) at the request of Lessor, hijacking (air piracy) insurance
reasonably satisfactory to Lessor; and (D) at the request of Lessor, war risk,
governmental confiscation and expropriation and related insurance, but only to
the extent (i) such insurance is maintained by Lessee with respect to other
aircraft operated by Lessee on the same routes as the Aircraft, or (ii) the
custom in the United States airline industry is to carry such insurance with
respect to aircraft operated on the same routes as the Aircraft.

         All such insurance shall be in full force and effect throughout any
geographical areas at any time traversed by the Aircraft, shall be payable in
dollars in the United States and be in substantially the amount usually carried
by corporations engaged in the same or similar business and similarly situated
with the Lessee; PROVIDED that all such insurance for each Aircraft shall during
the Term hereof be for an amount not less than the Stipulated Loss Value for
such Aircraft. Any hull insurance carried in accordance with this Section 12.02
may contain a provision for a deductible amount not to exceed, per occurrence,
$50,000. Any policies carried in accordance with this Section 12.02 covering the
Aircraft and any policies taken out in substitution or replacement for any such
policies: (1) shall name the Lessor as owner and as additional insured or loss
payee, as appropriate; (2) shall be made payable to all insureds as their

                                      12-3
<Page>

respective interests may appear; (3) shall provide that if such insurance is
cancelled or materially changed for any reason whatever, or the same is allowed
to lapse for non-payment of premium, such cancellation, change or lapse shall
not be effective as to the Lessor for thirty (30) days after receipt by the
Lessor of written notice by such insurers of such cancellation or lapse or
material change in policy terms and conditions (other than war risk insurance,
in which case seven days' notice shall be given); (4) shall provide that losses
shall be adjusted with the Lessor and Lessee as their interests may appear and
be payable to Lessor in the event of any damage or loss resulting in a payment,
for any one occurrence, in excess of $250,000; (5) shall provide that in respect
of the interest of the Lessor in such policies the insurance shall not be
invalidated by any action or inaction of the Lessee or any other person and
shall insure the Lessor regardless of any breach or violation of any warranties,
declarations or conditions contained in such policies by the Lessee or any other
person; (6) shall waive any right of set-off, counterclaim or other deduction
against each named insured; and (7) shall contain such other customary
provisions as Lessor may reasonably require. The Lessee shall arrange for
evidence of appropriate coverage for each Aircraft and to the satisfaction of
the requirements set forth above to be given to the Lessor on or before the
Delivery Date for each Aircraft by its insurance broker.

     12.03. APPLICATION OF PROCEEDS IN AN EVENT OF LOSS. Provided no Default or
Event of Default shall exist, it is agreed that all insurance payments received
as the result of the occurrence of an Event of Loss with respect to an Airframe
and installed Engines or any Engine will be applied as follows:

          (A) So much of such payments as shall not exceed the amount required
     to be paid by the Lessee pursuant to Section 11.01 shall to applied in
     reduction of the Lessee's obligation to pay such amount if not already paid
     by the Lessee or, if already paid by the Lessee, shall be applied to
     reimburse the Lessee for its payment of such amount, and the balance, if
     any, of such payment remaining thereafter will be paid over to, or retained
     by, the Lessee; and

          (B) If such payments are received with respect to an Engine under the
     circumstances contemplated by Section 11.02, such payments shall be paid
     over to, or retained by, the Lessee, PROVIDED that the Lessee shall have
     fully performed the terms of Section 11.02 with respect to the Event of
     Loss for which such payments are made.

          Any amount referred to in clause (A) or (B) above which is payable to
     Lessee shall not be paid to the Lessee if at the time of such payment a
     Default or an Event of Default shall have occurred and be continuing, but
     shall be held by the Lessor as security for the obligations of Lessee under
     this Lease and such amount shall be paid to Lessee at such time as there no
     longer exists any Default or Event of Default.

                                      12-5
<Page>

     12.04. APPLICATION OF PROCEEDS IN THE ABSENCE OF AN EVENT OF LOSS. As
between Lessor and Lessee, the insurance payments of any property damage loss to
an Airframe or any Engine not constituting an Event of Loss with respect thereto
will be applied (or advanced as may be required by the repair facility) in
payment for repairs or for replacement property in accordance with the terms of
Articles 6 and 9, if not already paid for by the Lessee (or to reimburse the
Lessee for such repairs or replacements already paid for by the Lessee), and any
balance remaining after compliance with such Articles with respect to such loss
shall be paid to the Lessee. Any amount referred to in the preceding sentence
which is payable to Lessee shall not be paid to the Lessee if at the time of
such payment Lessee shall not be current in its payment of Rent hereunder, but
shall be held by the Lessor as security for the obligations of Lessee under this
Lease and such amount shall be paid to Lessee at such time as Lessor has
received all Rent then due.

     12.05. REPORTS, ETC. On the Delivery Date for each Aircraft and annually on
the anniversary date thereof, the Lessee shall furnish to the Lessor a report
from the Lessee's insurance broker describing in reasonable detail the insurance
then carried and maintained on the Aircraft, certifying that such insurance
complies with the terms hereof and stating the opinion of such broker that such
insurance is adequate for the protection of the interests of the Lessor and the
Lessee in accordance with the terms hereof. The Lessee will advise the Lessor in
writing promptly of any default in the payment of any premium and of any

                                      12-6
<Page>

other act or omission on the part of the Lessee which might invalidate or render
unenforceable, in whole or in part, any insurance on an Aircraft. In the event
that the Lessee shall fail to maintain insurance as herein provided, the Lessor
may at its sole option provide such insurance and, in such event, the Lessee
shall thereupon reimburse the Lessor, as Supplemental Rent, for the cost
thereof; PROVIDED, HOWEVER, that no exercise by the Lessor of said option shall
affect the provisions of this Lease, including the provisions that failure by
the Lessee to maintain the prescribed insurance shall constitute an Event of
Default.

     12.06. ENDORSEMENTS. All policies of insurance required by this Lease shall
be in form and substance acceptable to Lessor.

     12.07. LESSOR'S ADDITIONAL INSURANCE. The Lessor may at its option and at
its sole expense carry insurance covering its interest in the Aircraft, in
addition to that required to be provided and maintained by the Lessee pursuant
to this Article 12, PROVIDED that no such insurance shall have the effect of
suspending, impairing, defeating, invalidating or rendering unenforceable or
reducing, in whole or part, the coverage of or the proceeds payable under any
insurance required to be provided and maintained by the Lessee pursuant to this
Article 12.

                             GENERAL INDEMNIFICATION

     13.01. The Lessee agrees to assume liability for, and does hereby
indemnify, protect, save and keep harmless the Lessor and its successors,
assigns, agents and servants from and against any and all claims, damages,
losses, liabilities (including, but not limited to, any claim or liability for
strict liability in tort or otherwise imposed including, without limitation,
liability arising under any applicable environment or noise or pollution control
statute, rule or regulation), obligations, demands, suits, penalties, judgments
or causes of action and all legal proceedings, whether civil or criminal,
penalties, fines and other sanctions, and any costs and expenses in connection
therewith including, without limitation, legal fees and, expenses of whatever
kind and nature (whether or not also indemnified against by any other person
under any other document), which may result from or grow or arise in any manner
out of the condition, ownership, manufacture, construction, design (including,
without limitation, latent and other defects whether or not discoverable by
Lessee or Lessor and any claim for patent, trademark or copyright infringement),
acceptance, non-acceptance, rejection, delivery, lease, possession, return,
disposition, use or operation (in each and every case) of the Aircraft or any
Item of Equipment either in the air or on the

                                      13-1
<Page>

ground (except claims arising out of the gross negligence or willful misconduct
of the Lessor or its successors or assigns), or arising from the material or any
article used therein or from the design, testing or use thereof or from any
maintenance, service, repair, overhaul or testing of the Aircraft or any Item
regardless of when such defect shall be discovered, whether or not such Aircraft
or any Item is at the time in the possession of the Lessee and whether it is in
the United States of America or any other country. The indemnities contained in
this Section shall continue in full force and effect notwithstanding the
assignment, expiration or other termination of this Lease.

     13.02. The Lessee hereby waives and releases any claim now or hereafter
existing against the Lessor and its successors or assigns-agents and servants on
account of any and all claims, demands, suits, judgments or causes of action for
or on account of or arising or in any way connected with injury to or death of
personnel of the Lessee or loss or damage to property of the Lessee or the loss
of use of any property which may result from or grow or arise in any manner out
of the condition, use or operation of the Aircraft or any Item, either in the
air or on the ground during the Term hereof, or which may be caused during the
Term hereof by any defect (whether

                                      13-2
<Page>

latent or patent) in the Aircraft or any Item from the material or, any article
used therein or from the design, testing or use thereof or from any maintenance,
service, repair, overhaul or testing of the Aircraft or any Item regardless of
when such defect shall be discovered, whether or not such Aircraft or any Item
is at the time in the possession of the Lessee and whether it is in the United
States of America or any other country.

     13.03. The Lessee further agrees that, with respect to any payment or
indemnity hereunder, such payment or indemnity shall include any amount
necessary to hold the recipient of the indemnity harmless on an after-tax basis
from all taxes required to be paid (or which would have been required to he paid
by Lessor with respect to such payment or indemnity had Lessor had sufficient
gross income within the meaning of Section 61 of the Code actually to pay tax at
the highest marginal rate) by such recipient with respect to such payment or
indemnity under the laws of any Federal, state or local government or taxing
authority in the United States, or under the laws of any taxing authority or
governmental subdivision of a foreign country; PROVIDED that, if any recipient
of a payment or indemnity realizes a tax benefit by reason of such payment or
indemnity (whether such tax benefit shall be by means of a depreciation
deduction or otherwise), such recipient shall pay the Lessee an amount equal to
the sum of such tax benefit plus any tax benefit realized as the result of any
payment made pursuant to this proviso, when, as, if and

                                      13-3
<Page>

to the extent realized; but not before the Lessee shall have made all payments
or indemnities to such recipient with respect to such loss pursuant to the
provisions of this Article 13. Each such recipient shall in good faith use
reasonable efforts in filing its tax returns and in dealing with taxing
authorities to seek and claim any such tax benefit.

     The Lessee shall not, directly or indirectly create, incur, assume or
suffer to exist any Lien on or with respect to any Item of Equipment or title
thereto or any interest therein, or in this Lease, except (i) the respective
rights of the Lessor and the Lessee as herein provided; (ii) Liens which result

indemnified against by the Lessee hereunder; (iii) Liens for taxes either not
yet due or being contested in accordance with Article 10 hereof; and (iv)
inchoate materialmen's, mechanics', workmen's, repairmen's, employees' or other
like liens arising in the ordinary course of business and for amounts the
payment of which is either not yet delinquent or is being contested in good
faith (and for the payment of which adequate reserves have been provided) by
appropriate proceedings so long as such proceedings do not involve any danger of
sale, forfeiture or loss of any Item of Equipment or any interest therein. The.
Lessee shall promptly, at its own expense, take such action as may be necessary
to duly discharge any such Lien not excepted above if the same shall arise at
any time with respect to an Item of Equipment leased hereunder.

                       RECORDATION AND FURTHER ASSURANCES

     15.01. The Lessee shall, at its expense, cause this Lease, all Exhibits
hereto, the Lease Supplements and any and all additional instruments which shall
be executed pursuant to the terms hereof so far as permitted by applicable law
or regulations, to be kept, filed and recorded and to be re-executed, refiled,
and re-recorded at all times in the office of the Aeronautics Authority,

other governmental authorities as the Lessor may reasonably request to perfect
and preserve the Lessor's rights hereunder, and the Lessee shall, as may be
reasonably requested by the Lessor, furnish to the Lessor an opinion of counsel
or other evidence satisfactory to the Lessor of each such filing or refiling and
recordation or re-recordation.

     15.02. Without limiting the foregoing, the Lessee shall do or cause to be
done, at the. Lessee's cost and expense, any and all acts and things which may
be required under the terms of the Convention for the International Recognition
of Rights in Aircraft, signed (ad referendum) at Geneva, Switzerland, on June
19, 1948, to perfect and preserve the Lessor's interest in and to the Aircraft
within the jurisdiction of any signatory State which

                                      15-1
<Page>

has ratified said Convention and in the territory of which the Lessee may
operate the Aircraft as the Lessor may reasonably request. The Lessee shall also
do or cause to be done, at its own expense, any and all acts and things which
may be required under the terms of any other agreement, treaty, convention, pact
or by any practice, custom, or understanding recognized as having wide
application or control involving any jurisdiction in which the Lessee may
operate, or any and all other acts and things which the Lessor may reasonably
request and which are necessary, to perfect and preserve the rights of the
Lessor hereunder, in and to any Item of Equipment, within any such jurisdiction.

     15.03. In addition, the Lessee will promptly and duly execute and deliver
to the Lessor such further documents and assurances and take such further action
as the Lessor may from time to time reasonably request in order to more
effectively carry out the intent and purpose of this Lease and to establish and
protect the rights and remedies created or intended to be created in favor of
the Lessor hereunder, including, without limitation, if requested by the Lessor,
at the expense of the Lessee, the execution and delivery of supplements or
amendments hereto, in recordable form, subjecting to this Lease any replacement
or substituted engine and the recording or filing of counterparts hereof, or of
financing statements with respect hereto, in accordance with the laws of such

such return. The Aircraft, upon redelivery pursuant hereto, (i) shall be duly
certified by the Aeronautics Authority as an airworthy aircraft, (ii) shall be

                                    REMEDIES

     Upon the occurrence of any Event of Default and at any time thereafter so
long as the same shall be continuing, the Lessor may, at its option, declare
this Lease to be in default and at any time thereafter, so long as the Lessee
shall not have remedied all outstanding Events of Default, the Lessor may
exercise one or more of the following remedies with respect to all or any part
of any Aircraft, Airframe or any Engine as the Lessor, in its sole discretion,
shall elect, to the extent available and permitted by applicable law then in
effect:

     18.01. Terminate this Lease and demand that the Lessee, and the Lessee
shal1 upon the written demand of the Lessor and at the Lessee's expense,
forthwith return the Aircraft and all Items of Equipment to the Lessor in the
manner and condition required by, and otherwise in accordance with all of the
provisions of, Article 16 hereof as if such Aircraft and Items were being
returned at the end of the Term; or the Lessor, at its option and to the extent
permitted by applicable law, may enter upon the premises where any Airframe, any
Engine or any Item of Equipment is located and take immediate possession of and
remove the same by summary proceedings or otherwise, all without liability
accruing to the Lessor for or by reason of

                                      18-1
<Page>

such entry or taking of possession whether for the restoration of damage to
property caused by such taking or otherwise.

     18.02. Sell or cause to be sold any Airframe, any Engine or any Item of
Equipment at public or private sale, as the Lessor may determine, or otherwise
dispose of, hold use, operate, lease to others or keep idle the Aircraft or any

and clear of any rights of the Lessee.

     18.03. Whether or not the Lessor shall have exercised, or shall thereafter
at any time exercise, any of its rights under Section 18.01 or 18.02 above with
respect to the Aircraft or any Item, the Lessor, by written notice to the Lessee
specifying a payment date not earlier than ten (10) days from such written
notice, may demand that the Lessee pay to the Lessor and the Lessee shall pay to
the Lessor, on the payment date specified in such notice, as liquidated damages
for loss of a bargain and not as a penalty (in lieu of the Basic Rent for the
Item due for periods commencing on or after the date specified for payment in
such notice), any unpaid Basic Rent for the Item due for periods prior to the
payment date specified in such notice plus whichever of the following amounts
the Lessor, in its sole discretion, shall specify in such notice: (A) an amount
equal to the excess, if any, of the

                                      18-2
<Page>

present worth of the aggregate unpaid Rent due under this Lease for such Item
discounted at the rate of seven percent (7%) per annum to the date specified in
said notice over the aggregate fair market rental value (computed as hereafter
in this Article provided) of such Item for the remainder of the Term for such
Item after discounting such fair market rental value to present worth as of the
payment date specified in such notice at the rate of seven percent (7%) per
annum; or (B) an amount equal to the excess, if any, of the Stipulated Loss
Value for such Item computed as of the date specified for payment in such notice
over the fair market sales value (computed as hereafter in this Article
provided) as of the date specified in the notice. The amount specified in said
notice shall bear interest at the Incentive Rate from the payment date specified
in said notice until receipt of payment by the Lessor.

     18.04. In the event the Lessor, pursuant to Section 18.02 above, shall
have sold or caused to have sold, any Item, the Lessor in lieu of exercising its
rights under Section 18.03 above with respect to such Item, may, if it shall so
elect, demand that the Lessee pay the Lessor and the Lessee shall pay to the
Lessor, as liquidated damages for loss of a bargain and not as a penalty (in
lieu of the Basic Rent for such Item due after such sale occurs), any unpaid
Basic Rent for such Item due for periods up to the time of sale plus the amount
by which the Stipulated Loss Value of such Item computed as of the date of such
sale exceeds the net cash proceeds (after deduction of all fees and expenses) of
such sale,

                                      18-3
<Page>

together with interest at the Incentive Rate on the sum of such excess and such
unpaid Rent from date of sale to the date such payment is received by the
Lessor.

     18.05. Proceed by appropriate court action or actions, either at law or in
equity, to enforce performance by the Lessee of the applicable covenants of this
Lease and to recover damages for the breach thereof, or to rescind this Lease as
to any Item.

     18.06. In addition, the Lessee shall be liable, except as otherwise
provided above, for any and all unpaid Rent due hereunder before or during the
exercise of any of the foregoing remedies and for all legal fees and other costs
and expenses incurred by reason of the occurrence of any Event of Default or the
exercise of the Lessor's remedies with respect thereto, including without
limitation all costs and expenses incurred in connection with the return of any
Item in accordance with the terms of Article 16 hereof or in placing such Item
in the condition and with airworthiness certificates as required by said
Article.

     18.07. For the purpose of Section 18.03 above, the "fair market rental
value" or the "fair market sales value" of any Item shall be as specified in an
appraisal by a recognized independent aircraft appraiser, chosen by the Lessor,
who shall determine such value(s) on the basis of the lesser of the

                                      18-4
<Page>

actual location and condition of the Item or the location and condition required
upon the return thereof pursuant to this Lease. At any sale of any Item pursuant
to this Article 18, Lessor, or any assignee, successor or affiliate of Lessor,
may bid for and purchase such property.

     18.08. Except as otherwise expressly provided above, no remedy referred to
in this Article is intended to be exclusive, but each shall be cumulative and in
addition to any other remedy referred to above or otherwise available to the
Lessor at law or in equity; and the exercise or beginning of exercise by the
Lessor of any one or more of such remedies shall not preclude the simultaneous
or later exercise by the Lessor of any or all of such other remedies. No express
or implied waiver by the Lessor of any Event of Default shall in any way be, or
be construed to be, a waiver of any future or further Event of Default. To the
extent permitted by applicable law, Lessee hereby waives any and all rights to
notice and to a judicial hearing with respect to the repossession of any Item by
the Lessor in the event of a Default by the Lessee and agrees that, except as
provided in this Article 18, any financing profit or savings accruing to the
Lessor by virtue of the Lessee's Default and subsequent sale, reletting or award
shall in no way reduce, offset or mitigate the damages for which the Lessee is
liable hereunder.

                                      18-5
<Page>

     18.09. To the extent consistent with the provisions of 11 U.S.C. Section
1110 or any corresponding provisions of subsequent law, it is expressly agreed
and provided that the title of the Lessor to the Aircraft and any right of the
Lessor to take possession of the Aircraft in compliance with the provisions
hereof shall not be hindered by the provisions of Chapter 11 or corresponding
provisions of Title 11 U.S.C. as amended from time to time.

     19.03. LESSOR'S RIGHT TO PERFORM FOR LESSEE. If the Lessee fails to make
any payment of Rent required to be made by it hereunder or fails to perform or
comply with any of its

                                      19-2
<Page>

agreements contained herein or in related documents, the Lessor may itself make
such payment or perform or comply with such agreement, and the amount of such
payment and the amount of the reasonable expenses of the Lessor incurred in
connection with such payment or the performance of or compliance with such
agreement, as the case may be, together with interest thereon at the Incentive
Rate, shall be deemed Supplemental Rent, payable by the Lessee upon demand.

     19.04 COUNTERPARTS. 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.

     19.05. QUIET ENJOYMENT. The Lessor covenants that if, and as long as, the
Lessee keeps and performs each and every covenant and agreement to be performed
or observed by it hereunder, the Lessee shall quietly enjoy the Aircraft without

the Aircraft through the Lessor.

     19.06. LEGAL FEES AND OTHER EXPENSES. The Lessee shall pay or reimburse the
Lessor for all out-of-pocket expenses incurred by the Lessor, including but not

                                      19-3
<Page>

Default or the exercise of the Lessor's remedies with respect thereto, including
all costs and expenses incurred in connection with the return of an Airframe. It
is understood and agreed that in any litigated action, proceeding, controversy
or dispute of any kind whatever in connection with the enforcement of rights
under this Lease, the prevailing party shall be entitled to recover its
expenses, including reasonable attorneys' fees, from the other party.

     19.07 ASSIGNMENT BY LESSOR. (a) Lessee acknowledges and agrees that Lessor
shall have the absolute right to transfer or assign to any person, firm,
corporation or other entity any or all of Lessor's rights, obligations, benefits
and interests under this Lease, including, without limitation, the right to
receive Rent or any other payment due under this Lease, the right to transfer or
assign title to any Item or to transfer or assign the right to purchase any Item
and the right to make all waivers and agreements, to give all notices, consents
and releases, to take all action upon the occurrence of an Event of Default, or
to do any and all other things which Lessor is or may become entitled to do
under this Lease. Lessee acknowledges that, if Lessor should sell or transfer to
a third party all of Lessor's interest under this Lease and in the Aircraft,
Lessor shall thereupon be relieved of all of its obligations hereunder and
Lessor's transferee shall succeed to all of Lessor's rights, interests and
obligations under this

                                      19-4
<Page>

Lease as though Lessor's transferee had been the initial lessor hereunder.

     (b) Without limiting the generality of paragraph (a), Lessee acknowledges
and agrees that the terms and conditions of this Lease have been agreed to by
Lessor in anticipation of its being able to assign its rights under and
interests in this Lease and its rights in the Aircraft and/or its being able to
grant a security interest in all or any of its rights and interest under this
Lease and in the Aircraft or any Item to one or more lenders, to an agent or
trustee representing such lenders, or to any other party having an interest in
any Item or participation in the transaction which is the subject of this Lease,
any or all of which may rely on and shall he entitled to the benefit of the
provisions of this Section 19.07(b). Lessee shall, upon the reasonable written
instruction of Lessor: (a) recognize any such assignment, (b) accept the
directions or demands of such assignee (if such directions or demands would be
permissible from Lessor under the terms of this Lease) in place of those of
Lessor, (c) surrender any leased property only to such assignee, (d) pay all
Rent payable hereunder and do any and all things required of Lessee hereunder,
and not terminate this Lease, notwithstanding any default by Lessor or the
existence of any other liability or obligation of any kind or character on the
part of Lessor to Lessee whether or not arising hereunder, (e) not require any
assignee of this Lease to

                                      19-5
<Page>

perform any duty, covenant or condition required to be performed by Lessor under
the terms of this Lease unless such assignee assumes all Lessor's interest in
the Aircraft and this Lease, all rights of Lessee in any such connection
aforesaid being hereby waived as to any and all such assignees (but not waived
as to Lessor), and (f) execute any documents which Lessor may reasonably request
in order to effectuate the foregoing.

     19.08. SURVIVAL. The representations, warranties, indemnities and
agreements of the Lessee provided for in this Lease, and the Lessee's
obligations under any and all provisions thereof, shall survive the expiration
or other termination of this Lease to the extent required for full performance
and satisfaction hereof.

     19.09. SUCCESSORS AND ASSIGNS. This Lease shall be binding on and shall
inure to the benefit of Lessee, Lessee's permitted successors and assigns,

                                 PURCHASE OPTION

     20.1. PURCHASE OPTION. Provided no Event of Default shall have occurred and
be continuing hereunder, Lessee, by irrevocable written notice delivered to
Lessor not later than 180 days prior to the end of the Term, may, at the end of
the Term, purchase the Aircraft for a purchase price in cash equal to the then
fair market sales value of the Aircraft determined as hereinafter provided;
provided that in no event shall the purchase price exceed fifty three percent
(53%) of Lessor's Cost.

     The then fair market sales value for a purchase shall be determined by
agreement between Lessor and Lessee, such determination to be based upon the
assumption that the Aircraft is in at least as good a condition as required by
the return conditions in Article 16 hereof. In the event Lessor and Lessee have
not agreed on the fair market sales value of the Aircraft prior to 90 days
before the expiration date of this Lease, the Lessor shall choose a recognized,
independent aircraft appraisal company which it shall engage to determine the
fair market sales value of the Aircraft, such appraisal to be binding on both
parties and the cost of which is to be borne by Lessee.

                                   ARTICLE 21

                   CHARACTERIZATION AS LEASE AND TAX INDEMNITY

     It is the intent of the parties that this Lease be a true lease and that
Lessor shall at all times be considered the owner of the Items for purposes of
all federal, state and local income or franchise taxes measured by net income,
and that this Lease conveys no right, title or interest in the Items to Lessee,
except as lessee. Lessee represents, warrants and covenants that neither it nor
any person controlled by it, in control of it, or under common control with it,
directly or indirectly, will at any time take any action or file any return or
other document inconsistent with the foregoing and that each of such persons
will file such  returns, take such actions and execute such documents as may be
reasonable and necessary to facilitate accomplishment of the intent hereof.

     21.01. TAX ASSUMPTIONS. The Lessor and the Lessee acknowledge that this
Lease has been entered into on the assumption that (i) for Federal income tax
purposes the Lease will be treated as a "true lease", (ii) for Federal income
tax purposes Lessor will be allowed to deduct as accelerated cost recovery
deductions under Section 168(b) of the Code commencing on the

                                      21-1
<Page>

Delivery Date, with respect to each Item of Equipment, the Lessor's Cost over
seven years based on the 200 percent declining balance method, switching to the
straight-line method for the first taxable year of the Lessor for which using
the straight-line method with respect to the adjusted basis of each Item of
Equipment at the beginning of such year will yield a higher allowance and
utilizing a salvage value of zero percent (0%); (iii) for Federal income tax
purposes all items of income and deduction relating to the Items of Equipment
will be treated as being from sources within the United States, and (iv)
Lessee's payments of Basic Rent, with respect to each Item of Equipment, will
constitute income to the Lessor, for Tax purposes, in the amounts and for the
respective periods determined on the assumption that such amounts will be
includable in Lessor's income, for Tax purposes, as they accrue under the Lease
and that such amounts will be the only income to be realized by the Lessor, for
Tax Purposes, from or with respect to each Item of Equipment or this Lease
Agreement, except for indemnity payments made to Lessor pursuant to this Article
and Articles 10 and 13 hereof. Such tax assumptions are hereinafter referred to
as the "Tax Benefits".

                                      21-2
<Page>

     21.02. TAX INDEMNITY. If for any taxable year of Lessor during which the
Lease is in effect Lessor shall lose (upon audit, by being unable to claim,
through recapture, or by not getting the benefit of, or otherwise) as a result
of Lessee's action or failure to act, excluding actions or failures to act
expressly required hereunder, all or any portion of any of the Tax Benefits, the
Lessee shall pay to Lessor an amount which, after deduction of all taxes
required to be paid (or which would have been required to be paid by Lessor had
Lessor had sufficient gross income within the meaning of Section 61 of the Code,
and the applicable state and local law, actually to pay tax) by Lessor in
respect of the receipt of such sum under the laws of any Federal, state or local
government or taxing authority in the United States (after giving credit for any
savings in respect to any such taxes by reason of deductions, credits or
allowances in respect of the payment or accrual of the amount indemnified
against), shall be equal to the sum of any additional Federal, state or local
income taxes payable by Lessor as a result of the loss of, such Tax Benefits (or
which would have been required to be paid by Lessor for such loss of Tax
Benefits had Lessor had sufficient gross income within the meaning of Section 61
of the Code, and the applicable state and local law, actually to pay tax or to
derive the benefit of such credit or deduction), plus the amount of any
interest, additions to tax (including, without limitation, an addition to tax by
reason of any underpayments of any estimated taxes), fines or penalties which

                                      21-3
<Page>

are payable by Lessor in connection with the loss of such Tax Benefits,
PROVIDED that the Lessee shall not be required to make any of the foregoing
indemnity payments to the extent the loss of the Tax Benefits is the result of:
(a) any event whereby Lessee is required by the terms of the Lease to pay, and
shall have paid in full, the Stipulated Loss Value for the Item of Equipment
with respect to which the loss of Tax Benefits arose; (b) Lessor's voluntarily
or involuntarily transferring legal title to all or any part of the interest in
such Item of Equipment unless such transfer occurs by reason of exercise of
Lessor's remedies under the Lease upon an Event of Default; (c) the failure of
Lessor to have sufficient liability for tax against which to apply any Tax
Benefits which may be taken as a credit or to have sufficient gross income
against which to apply any Tax Benefit which may be taken as a deduction (but
only if and to the extent that such credit or deduction would not be lost if
Lessor had sufficient liability for tax or sufficient gross income); (d) the
failure of Lessor to claim any Tax Benefit in its income tax returns for the
appropriate year or to follow proper procedure in claiming any Tax Benefit in
such tax returns for such year, if such failure to claim or follow proper
procedure shall preclude Lessor from claiming such Tax Benefit unless (i) such
failure is due to the failure of Lessee to provide Lessor in a timely manner
with such information as was reasonably requested by Lessor pursuant to this
Lease, or (ii) in the opinion of independent tax

                                      21-4
<Page>

counsel selected by Lessor, no substantial authority for such claim exists
or (iii) the matter in question is of a continuing nature and such matter
(although not in respect of the particular taxable year) has previously been
decided adversely to Lessor pursuant to the contest provisions of this Section;
(e) the failure of Lessor to take timely action in contesting a claim made by
any taxing authority with respect to the disallowance of any Tax Benefits if
such failure shall preclude the right of Lessor to contest such claim and if
such failure was not caused by Lessee's failure to request action by the Lessor
after receipt of notice from the Lessor or to otherwise comply with the
obligations under the contest provisions of this Section; (f) any act (whether
voluntary or involuntary), omission or misrepresentation of Lessor other than
any action or omission contemplated in the Lease Agreement or any related
agreements or otherwise taken by Lessor in the exercise of any. remedies or the
enforcement of any rights against Lessee under any of such agreements; (g) any
amendment to the laws of any Federal, state or local government or taxing
authority, which amendment is enacted after March 1, 1988; or (h) a
determination by any Federal, state or local government or taxing authority that
the Lease shall not be treated as a "true lease" unless such determination is a
result of Lessee's action or failure to act (excluding actions or failures to
act expressly required by this Lease).

     Except as otherwise provided in the immediately following paragraph, the
liability of the Lessee to make any indemnity

                                      21-5
<Page>

payments hereunder shall become fixed at the time the Lessor makes payment of
the tax attributable to the portion of the Tax Benefits lost, or if the Lessor
is not required to make payment of tax with respect to the portion of the Tax
Benefits lost, the date on which the Lessor files its tax return for the taxable
year in which such loss occurs, and shall he due and payable within 15 days
after receipt by Lessee of written notice from Lessor as to the fixing of such
liability. Lessee shall pay interest at the Incentive Rate on any indemnity
payment not made when due.

     21.03. CONTEST.

     (A) In the event a claim shall be made by the Internal Revenue Service
which, if successful, would result in a loss for which Lessee would have
liability to Lessor pursuant to this Article 21 of the Lease, Lessor hereby
agrees to take such action, in good faith, in connection with contesting such
claim as the Lessee shall reasonably request in writing, provided, that: (i)
within thirty (30) days after notice by Lessor to the Lessee of such claim the
Lessee shall have requested that such claim be contested; (ii) Lessor at its
sole option, may forego any and all administrative appeals, proceedings,
hearings and conferences with the relevant taxing authority in respect to such
claim and may, at its sole option, either pay the tax claimed and sue for a
refund in the appropriate forum selected by Lessor or contest such claim in the
appropriate forum selected by Lessor; (iii) within thirty (30) days after notice
by Lessor to Lessee of such claim, the Lessee shall have

                                      21-6
<Page>

furnished Lessor with an opinion of independent tax counsel chosen by the Lessee
and acceptable to Lessor, both as to counsel and substance, to the effect that
Lessor is more likely than not to prevail in contesting such claim; and (iv) the
Lessee shall have indemnified Lessor in a manner satisfactory to Lessor for any
cost, expenses or liability, which Lessor may incur as a result of contesting
such claim, and the Lessee shall agree to reimburse Lessor on demand, for all
costs, expenses and liability which Lessor may incur in contesting the claim,
and to pay all reasonable costs and expenses which Lessor may incur in
contesting the claim. These costs and expenses shall include, without
limitation, (a) reasonable attorneys' and accountants' fees and disbursements,
and (b) the amount of any interest, penalties or additions to tax indemnified
hereunder that may ultimately be payable as a result of contesting such claim.

     In the event that at any time Lessor shall pay the tax claimed and then
seek a refund, the Lessee shall pay to Lessor (as a "prior payment") the amount
of such tax and interest, additions to tax and penalties thereon, if any, but
not in excess of the amount which the Lessee would be obligated to pay in
respect of the related Loss under this Article of the Lease. Upon Final
Determination of the liabilities of Lessor, or the receipt of a refund by
Lessor, Lessor shall offset the amount of such prior payment against the full
amount due, if any, pursuant to the provisions of this Article and either (i)
the Lessee shall pay to Lessor within 15 days after notice

                                      21-7
<Page>

thereof, any excess of such full amount due, if any, over such prior payment, or
(ii) Lessor shall repay to the Lessee within 15 days after the late of a
receipt of such refund or notice of such Final Determination, any excess of such
prior payment over such full amount due. Any interest received by Lessor in
connection with any refund which is allocable to the indemnified taxes paid by
Lessor in respect of which the Lessee had made a prior payment shall be for the
account of the Lessee.

     (B) In the case of any such claim, Lessor agrees to notify the Lessee
promptly in writing of such claim, agrees not to make payment of the tax or
other liability claimed for at least thirty (30) days after the giving of such
notice (unless specifically required to do so at an earlier date by the Internal
Revenue Service), and agrees to cooperate with the Lessee in good faith in order
that such claim may be contested effectively. The Lessee and its counsel shall
maintain confidentiality with respect to all such information insofar as is
possible, consistent with the conduct of a contest hereunder.

     (C) Lessor shall not enter into a settlement or other compromise with
respect to, or otherwise concede, any claim without the written consent of
Lessee, which consent shall not be unreasonably withheld, unless Lessor waives
its right to be indemnified with respect to such claim (but not with respect to
any future claims) under this Article of the Lease. Lessee shall not be
considered to have unreasonably withheld such consent if such consent shall be
withheld as a result of Lessee's reasonable evaluation of the merits of the
basis for

                                      21-8
<Page>

contesting such claim and Lessee shall not be required to consider any issue or
dispute not directly related to such claim.

     (D) If Lessee requests Lessor to contest a claim and otherwise complies
with its obligations under this Section 21.03, it shall have no obligation to
pay any indemnity under this Article of the Lease resulting from such claim
until a Final Determination occurs regarding the liability of Lessor in respect
of the claim. Lessee's obligation to pay the indemnity shall become fixed upon
such Final Determination and unless otherwise provided in this Section 21.03
shall be payable within 15 days after receipt by Lessee of written notice from
Lessor as to the occurrence of a Final Determination. In all other cases, the
liability of Lessee shall become fixed and payable as provided in Section 21.02
of the Lease:

     (E) For purposes of this Section 21.03, "Final Determination" shall mean a
decision of a court of original jurisdiction with respect to such claim,
(provided that the time for filing an appeal of such decision has expired) or
other disposition of such claim in the manner contemplated herein.

     21.04. SURVIVAL. The indemnification provided herein shall survive the
assignment, expiration or other termination of this Lease.

     21.05. CONSOLIDATED RETURN. For purposes of this Article 21, the term
"Lessor" shall mean and include the affiliated group of corporations and each
member thereof,

                                      21-9
<Page>

within the meaning of section 1504 of the Code, of which Lessor is a member, if
such group is filing a consolidated United States Federal income tax return, and
it shall also mean any consolidated or combined group of corporations of which
Lessor is a member which is treated as such for state franchise tax purposes.

interest in the Aircraft except as a lessee.

for the execution and delivery from time to time of Lease Supplements each

the Lease as and when delivered by the Lessor to the Lessee in accordance with
the terms thereof;

     NOW, THEREFORE, in consideration of the premises and other good and
sufficient consideration, and pursuant to Article 2 of the Lease, the Lessor and
the Lessee hereby agree as follows:

     1.    The Lessor hereby delivers and leases to the Lessee, and the Lessee
     hereby accepts and leases from the Lessor, under the Lease Agreement, as
     herein supplemented, the following:

     (i)   Airframe: Saab Scania AB, Saab SF340A, FAA Registration N125CH,
     manufacturer's serial no, 340A-125.

     (ii)  Engines: General Electric model CT7--5A2, manufacturer's serial nos.

          manufacturer's serial numbers DRG/5453/88 and DRG/5454/88 (the
          "Propellers"), to which were attached the Purchase Option Agreement
          dated September 29, 1988 (the "option Agreement") between the Lessor
          as grantor and the Lessee as grantee and the Assignment of Lease
          Agreement dated as of August 25, 1988 (the "Lease Assignment") between
          the Lessee as assignor and Manufacturers Hanover Trust Company of
          California, as Trustee (the "Trustee") under the Second Amended and
          Restated Trust Agreement dated as of June 25, 1987 (the "Trust
          Agreement"), were recorded as Conveyance No. D93469; and

     (c)  Lease Supplement No. 2 dated as of September 29, 1988 (the "Sublease
          Supplement") between the Trustee as sublessor and Chautauqua Airlines,
          Inc. as sublessee (the "Sublease"), which supplemented the Lease
          Agreement dated as of August 15, 1988 (the "Sublease") between the
          Lessee as sublessor and the Sublessee to cover the Aircraft, the

          dated as of August 25, 1988 (the "Sublease Assignment"), was recorded
          as Conveyance No. D93470.

     Subsequent to the recordations mentioned above, we examined the records
maintained by the FAA for the Aircraft and what were represented to us by FAA
personnel as being all of the encumbrance cross-reference index cards in
existence for the Engines and the Propellers. Based upon such examination, it is
our opinion that:

     (a)  the retained legal title to the Aircraft is vested in the Lessor, with
          a Certificate of Aircraft Registration duly issued to the Trustee
          pursuant to and in accordance with the provisions of the Federal
          Aviation Act of 1958, as amended (the "Act");

     (b)  the Aircraft, the Engines and the Propellers are free and clear of any
          Liens (as such term is defined in the Lease) except such as are
          created by the Lease, as supplemented by the option Agreement and as
          assigned by the Lease Assignment, and the Sublease, as assigned by the
          Sublease Assignment and as supplemented by the Sublease Supplement;
          and

<Page>

     (c)  the FAA Bill of Sale, the Lease with the Option Agreement and the
          Lease Assignment attached and the Sublease supplement have been duly
          recorded by the FAA pursuant to and in accordance with the provisions
          of the Act.

          This opinion is subject to the same limitations and exceptions as were
set forth in the last paragraph of our opinion letter to you dated September 29,
1988, covering the Aircraft, the Engines and the Propellers.

                                             Very truly yours,
                                             /s/ Preston G. Gaddis II
