RE: Letter of Agreement
    Indianapolis International Airport

Dear Hal:

In a meeting with Jeannie Weiss, Eric Anderson and myself on March 28, 2000, you
and Wayne Heller requested that the vestibule on the Fourth Floor of
Chautauqua's leased premises be removed from your leasehold.

According to my calculations, this vestibule is approximately 289.8 square feet.
This removal of space will affect not only your current rental rates, but the
two remaining option periods Chautauqua has on this fourth floor space. The
removal of this 289.8 square feet will leave a total of 4,894.85 square feet on
fourth floor office space. The following are calculations for the current rental
period and the two option periods remaining:

     AUGUST 1, 2000 THROUGH JU1Y 31, 2001

     4894.85 sq. ft. X $11.00 per sq. ft. = $53843.35 per year, payable at
     $4486.95 per month

     AUGUST 1, 2001 THROUGH JULY 31, 2002

     4894.85 sq. ft. X $11.50 per sq. ft. = $56290.78 per year, payable at
     $4690.90 per month.

     AUGUST 1, 2002 THROUGH JULY 31, 2003

     4894.85 sq. ft. X $ 12.00 per sq. ft. = $58738.20 per year, payable at
     $4894.85 per month.

This removal of leasehold will be made effective April 1, 2000 and the
appropriate rental credit for the months of April through August will be issued
to Chautauqua.

Please remember that the removal of this vestibule from Chautauqua's leasehold
opens this area up to the public. The double glass doors in the hallway will be
removed, and the keycores to both the middle stairwell and elevators will be
changed to allow for common usage.

Please sign below to indicate your acceptance of this Letter of Agreement to
remove 289.8 square feet from Chautauqua's leasehold. Please call me at 487-5225
if you have any questions or concerns.

Sincerely,

/s/ Andria A. Kerney

      2.1. AGREEMENT TO LEASE. Lessor hereby agrees, subject to satisfaction of
the conditions set forth herein, to lease to Lessee hereunder, and Lessee hereby
agrees to lease from Lessor hereunder, the Aircraft, as evidenced by the
execution by Lessor and Lessee of this Lease, a Lease Supplement leasing the
Aircraft hereunder and execution and delivery by Lessee of an Acceptance
Certificate. Lessee hereby agrees that such acceptance of the Aircraft by Lessee
shall, without further act, irrevocably constitute acceptance by Lessee of such
Aircraft for all purposes of this Lease.

2.2.  TERM OF THE LEASE.

      (a) BASIC TERM. The Basic Term of this Lease shall be fifteen years from
the Commencement Date, unless sooner terminated in accordance with the
provisions hereof (the "Termination Date").

      (b) RENEWAL TERM(S). The Renewal Term(s) shall be as described in Section
22.

      2.3. RENT.

      (a) BASIC RENT. Lessee shall promptly pay (or cause to be paid) to Lessor
Basic Rent during the Basic Term on each Rent Payment Date in the amount
provided in Schedule I to this Lease.

      (b) RENEWAL RENT. Lessee shall promptly pay (or cause to be paid) to
Lessor Renewal Rent on each Rent Payment Date during the Renewal Term in the
amount determined pursuant to Section 22 hereof).

      (c) SUPPLEMENTAL RENT. Lessee shall promptly pay (or cause to be paid) to

hereunder. In the event of any failure on the part of Lessee to pay any

for herein or by law or equity or otherwise in the case of

                                      6
<Page>

nonpayment of Basic Rent. Interest on past due Basic Rent shall be computed at
the Past Due Rate, and shall be considered Supplemental Rent. The expiration or
other termination of Lessee's obligation to pay Basic Rent hereunder shall not
limit or modify Lessee's obligations with respect to Supplemental Rent.

      (d) ADJUSTMENTS TO BASIC RENT. Following the Delivery Date, all
installments of Basic Rent remaining to be paid during the Basic Term shall be
recalculated and adjusted, upward or downwards as the case may be (and
corresponding adjustments shall be made to the Stipulated Loss Values and the
Termination Values applicable during the remaining Basic Term), in the event
that (i) the Transaction Costs payable by Lessor are more or less than [*] of
Lessor's Cost (unless Lessee elects to pay such excess directly), and/or (ii)
any tax indemnity payment is financed through a Basic Rent adjustment. Such
adjustment shall be made in such manner as to maintain the Net Economic Return
and to minimize the greatest extent practicable consistent therewith, the
mathematical average of the remaining Basic Rent payments. Adjustments to the
installments of Basic Rent (expressed as percentages of Lessor's Cost) and
conforming adjustments to the Stipulated Loss Values and Termination Values
shall be calculated by Lessor in accordance with the terms of this Section 3(c).
Lessor shall deliver to Lessee schedules setting forth the revised amounts,
which shall be subject to review by Lessee and verification as provided herein.
In the event that a dispute regarding any such adjustment is not resolved by
written agreement of Lessor and Lessee within 30 days following receipt by
Lessee of Lessor's schedules of proposed adjustments, Lessee shall have the
right by written notice to Lessor within 30 days after receipt of Lessor's
proposed adjustments to cause a lease advisory firm or a nationally-recognized
firm of accountants selected by Lessor and reasonably acceptable to Lessee to
verify shall proposed adjustments. Lessor shall provide to such firm, but not,
in any circumstances, to Lessee or any representatives of Lessee, on a
confidential basis, such information as such firm may reasonably require,
including, without limitation, a true copy of this Lease and a full description
of the methodology and assumptions employed by Lessor in calculating the Basic
Rent and Stipulated Loss Values and Termination Values as in effect on the
Delivery Date and a true copy of the calculations of the adjustments performed
by Lessor at the time, to enable such firm to determine whether the adjustments
proposed by Lessor are mathematically accurate, apply the same methodology and
assumptions (except to the extent changed by the events giving rise to such
recalculation) as were employed in the calculations of the Basic Rent,
Stipulated Loss Values and Termination Values in effect on the Delivery Date,
and are otherwise in conformity with the provisions of this Lease. Lessee and
its financial advisors shall be entitled to submit to such firm such data and
views concerning the proposed adjustments as Lessee may elect. The firm shall be
requested to deliver to each of Lessor and Lessee within 30 days after its
appointment its determination as to the changes, if any, that are appropriate
with respect to the adjustments proposed by Lessor. The adjustments proposed by
Lessor, if not disputed by Lessee as provided above, or the determination of the
firm as provided above, as the case may be, shall be conclusive, final and
binding upon Lessor and Lessee. No dispute concerning any adjustment shall
release Lessee from its obligations to pay the Basic Rent or Stipulated Loss
Value or Termination Value as then set forth herein. All reasonable fees and
expenses payable to the outside firm pursuant to this Section 3(c) shall be paid
by Lessee, except that such fees and expenses shall be shared equally by Lessor
and Lessee if, as a result of changes determined by the firm, the net present
value, discounted at the Base Rate, of Basic Rent

                                      7

remaining to be paid is [*] or more lower than it would have been under the
adjustments proposed by Lessor. Any adjustments made pursuant to this Section
3(c) shall (i) be made so as to avoid characterization of this Lease as a
"disqualified leaseback or long-term agreement" within the meaning of Section
467 of the Code and the Treasury Regulations promulgated thereunder, and (ii)
comply with the requirements of Revenue Procedure 75-21 and 75-28 (or any
successor relevant procedures), except to the extent that on the Delivery
Date the Lease constituted such a "disqualified leaseback or long-term
agreement" or was not in compliance with the revenue procedure referred to
above. All adjustments required pursuant to this Section 3(c) shall be set
forth in a Lease Supplement or in an amendment to this Lease.

      (e) PAYMENTS IN GENERAL. All payments of Rent shall be made to Lessor in
the United States of America by wire transfer of immediately-available funds
prior to noon (12:00) p.m. Eastern time on the due date thereof, to Lessor's

44114, ICX Corporation account no. 40-0113830, ABA number 241-070-417 (or such
other account as Lessor shall direct in a written notice to Lessee at least five
Business Days prior to the date such payment of Rent is due). Notwithstanding
anything in this Lease to the contrary, if any date on which a payment of Rent
becomes due and payable is not a Business Day, such payment shall not be made on
such scheduled date but shall be made on the next succeeding Business Day with
the same force and effect as if made on such scheduled date and, provided such
payment is made on such next succeeding Business Day, no interest shall accrue
on the amount of such payment from and after such scheduled date.

SECTION 7. REGISTRATION; MAINTENANCE; OPERATION; POSSESSION; PERMITTED

      7.1.  REGISTRATION.

      (a) On the Delivery Date, Lessee shall, at its own cost and expense, cause
this Lease and the Lease Supplement to be duly filed with the FAA under the
Transportation Act, and except as provided in Section 7.1(b), Lessee shall not
take any action or fail to take any action that would cause the Aircraft not to
remain at all times duly registered under the Transportation Act unless Lessor
consents in advance in writing to the registration of the Aircraft in another
jurisdiction. Lessee shall execute and deliver all such documents at its own
cost and expense as Lessor may reasonably request for the purpose of effecting
and continuing such registration. In addition, Lessee shall take such other
actions as may be necessary in any other jurisdiction in which the Aircraft may
be operated to protect Lessor's interest as owner of the Aircraft and as Lessor
hereunder. Lessee shall have the right, upon written notice to Lessor, to cause
the United States registration number for the Aircraft to be changed to another
United States registration number selected by Lessee. Lessor agrees to cooperate
with Lessee, at Lessee's sole cost and expense, including, without limitation,
executing and delivering to Lessee a Form AC 8050-64, "Assignment of Special
Registration Number," for the Aircraft. Lessee shall solely be responsible for
the cost of painting its designated United States registration number on the
Aircraft and for all other costs associated with or resulting from the change of
the registration number of the Aircraft.

      (b) Lessee shall have the right, in connection with a Permitted Sublease
to a Permitted Sublessee pursuant to Section 13.2, to change the registration of
the Aircraft to any country listed on Schedule III hereto approved for
re-registration. Lessee's right to change the registration shall be subject to
appropriate recordation in the country of registry of the rights of Lessor,
provided

                                      14
<Page>

that Lessee shall deliver to Lessor an opinion of counsel reasonably
satisfactory in form and substance to Lessor to the effect that the rights of
Lessor in and to the Aircraft and the Lease and the obligations of Lessee under
the Lease will not be impaired under the laws of such country, Lessor will not
be required to qualify to do business in such jurisdiction as a result of such
re-registration, the laws of such Permitted Sublessee's country of domicile
require fair compensation by the government of such jurisdiction for the loss of
use of or title to such Engine or the Airframe in the event of the requisition
by such government of such use or title (it being understood that in the event
such opinion cannot be given in a form reasonably satisfactory to Lessor, such
opinion will be waived if insurance reasonably satisfactory to Lessor is
provided to cover such requisition) and provided, further, that Lessee shall
also provide Lessor with satisfactory assurances that the Lessor's title to the
aircraft will be recognized in such new jurisdiction of registry. In addition,
Lessee shall provide to Lessor evidence reasonably satisfactory to Lessor that
(i) the country of proposed re-registration provides promulgated guidelines
establishing that the prompt and orderly de-registration of the Aircraft will
not be unreasonably impeded, and (ii) the jurisprudence and laws of such country
do not clearly provide for greater tort liability to Lessor than under similar
circumstances in the United States. All costs incurred with such change of
registry shall be for the account of Lessee.

      7.2. MAINTENANCE. During the Term, Lessee, at its own cost and expense,
shall (or, if any Permitted Sublease is then in effect, shall cause any
Permitted Sublessee to):

      (a) maintain, inspect, service, repair, test, operate and overhaul (or
      cause to be maintained, inspected, serviced, repaired, tested, operated
      and overhauled) the Aircraft in accordance with the Maintenance Program so
      as to keep (A) the Aircraft in good operating condition, and (B) the
      Aircraft in such condition as may be necessary to enable the applicable
      airworthiness certification for the Aircraft to be maintained in good
      standing at all times under (I) the Transportation Act, except when a
      group of aircraft of the same type and series as the Aircraft powered by
      engines of the same type and series as those with which the Airframe is
      from time to time equipped and registered in the United States and flying
      in commercial passenger service have been grounded by the Federal Aviation
      Administration, and (II) the applicable laws of any other jurisdiction in
      which the Aircraft may then be registered, based and/or operated from time
      to time. In any event, the Aircraft shall be maintained at least at the
      level as Lessee maintains, and utilizing the same manner of maintenance,
      service, repair or overhaul as used by Lessee with respect to, similar
      aircraft owned, leased or operated by Lessee. Notwithstanding anything
      herein to the contrary, all maintenance, including "C" checks and engine
      overhauls, shall be performed by Lessee or an FAA-approved repair station;

      (b) maintain or cause to be maintained in the English language all Manuals
      and Technical Records, and other materials required to be maintained in
      respect of the Aircraft by the Federal Aviation Administration and the
      applicable regulatory agency or body of any other jurisdiction in which
      the Aircraft may then be registered and/or based from time to time,
      including, but not limited to, all documents necessary to establish
      compliance with applicable FAA requirements for the Airframe, the Engines
      and life-limited parts (which records, logs and other materials, as
      between Lessor and Lessee and

                                      15
<Page>

      all parties claiming through Lessee, shall be the property of Lessor but
      shall be maintained by Lessee during the Term of this Lease and shall
      become the property of Lessee upon the occurrence of an Event of Loss and
      Lessee's compliance with Section 10.1); and

      (c) promptly furnish or cause to be furnished to Lessor such information
      as may be required to enable Lessor to file any reports required to be
      filed by Lessor with any governmental authority or lending institution.

      7.3. COMPLIANCE WITH AIRWORTHINESS DIRECTIVES. Lessee shall ensure at its
cost and expense that the Aircraft shall at all times have a currently effective
airworthiness certificate issued by the FAA under the Federal Aviation
Regulations (or by any other governmental authority having jurisdiction over the
operation of the Aircraft). Lessee (or during the term of any Permitted
Sublease, the Permitted Sublessee), at its cost and expense, shall ensure that
the Aircraft is in compliance with all applicable Airworthiness Directives, and
Federal Aviation Regulation requirements (or the requirements of any other
governmental authority having jurisdiction over the Aircraft). All Airworthiness
Directives shall be accomplished in accordance with all applicable bulletins and
manuals published by the manufacturer of the Airframe or Engines or Parts or
FAA-approved data developed by Lessee, and in a manner consistent with similar
aircraft owned, leased or operated by Lessee.

      7.4. REPLACEMENT OF PARTS. Lessee (or, if any Permitted Sublease is then
in effect, any Permitted Sublessee), shall, at its own cost and expense,
promptly replace or cause to be replaced all Parts which may from time to time
be incorporated or installed in or attached to the Airframe or any Engine and
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, except as otherwise provided in Section 7.6. In addition,
Lessee (or, if any Permitted Sublease is then in effect, any Permitted
Sublessee) may, at its own cost and expense, remove in the ordinary course of
maintenance, service, repair, overhaul or testing, 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 any Permitted
Sublease is then in effect, any Permitted Sublessee), except as otherwise
provided in Section 7.6, will, at its own cost and expense, replace such Parts
as promptly as practicable. If not obtained from an original equipment
manufacturer, all Parts installed during the Term must have been
repaired/overhauled by an FAA-approved repair station and be accompanied by
appropriate certification and documentation to demonstrate compliance with
applicable requirements. All replacement Parts shall be free and clear of all
Liens (except for Permitted Liens and pooling arrangements to the extent
permitted by Section 7.5 and except for replacement property temporarily
installed on an emergency basis) and shall be in as good operating condition as,
and shall have a value, utility and remaining useful life at least equal to, the
Parts replaced, but in all events such replacement Parts shall be no less than
in the condition and repair required to be maintained by the terms hereof. All
Parts at any time removed from the Airframe or any Engine shall remain the
property of Lessor, no matter where located, until such time as such Parts have
been replaced by Parts which have been incorporated or installed in or attached
to the Airframe or such Engine and which meet the requirements for replacement
parts specified above.

                                      16
<Page>

Immediately upon any replacement part becoming incorporated or installed in or
attached to the Airframe or any Engine as above provided, without further act
(subject only to Permitted Liens and any pooling arrangement to the extent
permitted by Section 7.5 and except for replacement property temporarily
installed on an emergency basis), (i) title to such replacement Part shall
thereupon vest in Lessor, (ii) such replacement Part shall become subject to
this Lease and be deemed part of the Airframe or such Engine for all purposes
hereof to the same extent as the Parts originally incorporated or installed in
or attached to the Airframe or such Engine, and (iii) title to the replaced Part
shall thereupon vest in Lessee (or, if a Permitted Sublease is then in effect,
any Permitted Sublessee), free and clear of all Lessor Liens and rights of
Lessor, and shall no longer be deemed a part hereunder.

      7.5. POOLING OF PARTS. Any Part removed from an Airframe or any Engine as
provided in Section 7.4 may be subjected by Lessee (or, if any Permitted
Sublease is then in effect, any Permitted Sublessee) to a customary pooling or
interchange arrangement with other aircraft or engines owned or leased by Lessee
(or, if any Permitted Sublease is then in effect, any Permitted Sublessee);
provided that if as a consequence thereof a Part is removed, the Part replacing
such removed Part shall be incorporated or installed in or attached to the
Airframe or Engine in accordance with Section 7.4 as promptly as practicable
after the removal of such removed Part. When incorporated or installed in or
attached to the Airframe or any Engine in accordance with Section 7.4, any Part
replacing a Part that is removed under a customary pooling or interchange
arrangement may be owned by any third party, provided that Lessee (or, if any
Permitted Sublease is then in effect, any Permitted Sublessee), at its cost and
expense, as promptly thereafter as practicable, either (i) causes title to such
replacement Part to vest in Lessor in accordance with such Section 7.4 by Lessee
(or, if any Permitted Sublease is then in effect, any Permitted Sublessee)
acquiring title thereto for the benefit of, and transferring such title to,
Lessor free and clear of all Liens other than Permitted Liens, or (ii) replaces
such replacement Part by incorporating or installing in or attaching to the
Airframe or Engine a further replacement Part owned by Lessee (or, if any
Permitted Sublease is then in effect, any 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 in accordance with Section 7.4. All such
replacement Parts shall be in as good operating condition as, and shall have a
value, utility and remaining useful life at least equal to, the Parts replaced,
but in all events such replacement Parts shall be no less than in the condition
and repair required to be maintained by the terms hereof. No pooling or
interchange arrangement will result in a change of title or registration of the
Aircraft or effect Lessor's status under this Lease.

      7.6. ALTERATIONS, MODIFICATIONS AND ADDITIONS. Lessee (or, if a Permitted
Sublease is then in effect, any Permitted Sublessee), shall, at its own cost and
expense, make (or cause to be made) such alterations and modifications in and
additions to the Airframe and Engines as may be required from time to time to
meet the applicable standards of the FAA or any applicable regulatory agency or
body of any other jurisdiction to which the Aircraft may then be subject, and
such other modifications, alterations and improvements as do not decrease the
fair market value utility or remaining useful life of the Aircraft. Title to all
Parts incorporated or installed in or attached or added to the Airframe or an
Engine as the result of such alteration, modification, removal or addition
shall, without further act, vest in Lessor. Notwithstanding the foregoing,

                                      17
<Page>

Lessee (or, if any Permitted Sublease is then in effect, any Permitted
Sublessee) may, at any time during the Term, so long as no Event of Default has
occurred and is continuing, remove or suffer to be removed any Part, provided
that such Part (i) is in addition to, and not in replacement of or substitution
for, any Part originally incorporated or installed in or attached to the
Airframe or any Engine at the time of delivery thereof hereunder or any Part in
replacement of or substitution for any such Part, (ii) is not required to be
incorporated or installed in or attached or added to the Airframe or any Engine
pursuant to the terms of Section 7.2(a) or the first sentence of this Section
7.6, (iii) can be removed from the Airframe or such Engine without (A) causing
material damage to the Airframe or such Engine (it being understood that Lessee
shall repair any damage caused by a permitted removal), or (B) diminishing or
impairing the value, utility, condition, remaining useful life or airworthiness
which the Airframe or such Engine would have had at such time had such
alteration, modification, removal or addition not originally occurred, assuming
such Airframe or such Engine was then of the value, utility, and remaining
useful life and in the condition of airworthiness required to be maintained by
the terms of this Lease, and (iv) was not paid for by Lessor; provided, however,
that the value of all parts removed pursuant to this sentence shall not exceed
$100,000 in the aggregate. Upon the removal by Lessee (or Permitted Sublessee)
of any Part as provided above, title thereto shall, without further act, vest in
Lessee (or any Permitted Sublessee, as the case may be) and such Part shall no
longer be deemed part of the Airframe or Engine from which it was removed. Any
Part not removed by Lessee (or any Permitted Sublessee) as above provided prior
to the return of the Airframe or Engine to Lessor hereunder shall remain the
property of Lessor.

      7.7.  OPERATION.

            (a) Lessee will not maintain, use, service, repair, overhaul,
operate or locate the Aircraft (or, if any Permitted Sublease is then in effect,
permit any Permitted Sublessee to maintain, use, service, repair, overhaul,
operate or locate the Aircraft) in violation of any law or any rule, regulation,
order, directive, bulletin or certificate of any government or governmental
authority (domestic or foreign) having jurisdiction, or in violation of any
airworthiness certificate, license or registration relating to the Aircraft
issued by any such authority, except to the extent Lessee (or, if a Permitted
Sublease is then in effect, any Permitted Sublessee) is contesting in good faith
the validity or application of any such law, rule, regulation or order in any
reasonable manner which does not involve any material risk of liabilities or any
civil or criminal penalties being imposed on or against Lessor, that does not
involve any material risk of loss, forfeiture or sale of the Aircraft or any
Engine, and that does not adversely affect Lessor, Lessor's title or interest in
the Aircraft or any Engine, or Lessor's interest in this Lease. Except as
provided in Section 7.3, if any such law, rule, regulation, order, directive,
bulletin, certificate, license or registration requires alteration of the
Aircraft or any Engine, Lessee will conform the same therewith at its own cost
and expense and will maintain the Aircraft and each Engine in compliance with
such law, rule, regulation, order, directive, bulletin, certificate, license or
registration.

            (b) Lessee will not operate or locate the Aircraft, or permit any
Permitted Sublessee to operate or locate the Aircraft, in any area excluded from
coverage by any insurance

                                      18
<Page>

policy required by the terms of this Lease, except in the case of temporary
operations due to unforeseen circumstances beyond Lessee's control (e.g.,
weather, hijacking, malfunctions, ETC.)

            (c) The Aircraft shall be operated only by pilots and other airmen
holding valid licenses or other necessary authorizations as may be required by
applicable laws and regulations.

      7.8.  POSSESSION AND PERMITTED SUBLEASES.

            (a) During the Basic Term, Lessee will not, without the prior
written consent of Lessor, sublease or otherwise in any manner deliver, transfer
or relinquish possession of the Aircraft, the Airframe or any Engine, or install
or permit to be installed any Engine on any airframe other than the Airframe, or
to install or permit to be installed on the Airframe any engines other than the
Engines (other than to the extent an Engine is receiving off-wing maintenance
service). The wet lease or charter of the Aircraft shall not be considered a
sublease; provided, however, that at all times, Lessee has operational control
of the Airframe and Engines.

            (b) Notwithstanding anything herein to the contrary, Lessee may,
without the prior written consent of Lessor:

                  (i) install a substitute engine owned by Lessee on the
            Airframe so long as the substitute engine is free and clear of all
            Liens except Permitted Liens;

                  (ii) install or permit the installation of an Engine on an
            airframe which is owned by Lessee (or, if any Permitted Sublease is
            then in effect, any Permitted Sublessee) free and clear of all Liens
            except (A) Permitted Liens and those which apply only to the engines
            (other than Engines), appliances, parts, instruments, appurtenances,
            accessories, furnishings and other equipment (other than Parts)
            installed on such airframe (but not to the airframe as an entirety),
            and (B) mortgage liens or other security interests, provided that
            such mortgage liens or other security interests effectively provide
            that such Engine shall not become subject to the lien of such
            mortgage or security interest, notwithstanding the installation
            thereof on such airframe;

                  (iii) provided no Event of Default has occurred and is
            continuing, install or permit the installation of an Engine on an
            airframe leased to Lessee (or, if any Permitted Sublease is then in
            effect, any Permitted Sublessee) or purchased by Lessee (or, if any
            Permitted Sublease is then in effect, any Permitted Sublessee)
            subject to a conditional sale or other security agreement, provided
            that (A) such airframe is and remains free and clear of all Liens
            except (I) the rights of the parties to the lease or conditional
            sale or other security agreement covering such airframe, or their
            assignees, and (II) Liens of the type permitted by Section
            7.8(b)(ii) hereof and (B) such lease, conditional sale or other
            security agreement expressly provides that such Engine shall not
            become subject to the lien of such

                                      19
<Page>

            lease, conditional sale or other security agreement, notwithstanding
            the installation thereof on such airframe; or

                  (iv) install or permit the installation of an Engine on an
            airframe owned by Lessee (or, if any Permitted Sublease is then in
            effect, any Permitted Sublessee), leased to Lessee (or, if any
            Permitted Sublease is then in effect, any Permitted Sublessee) or
            purchased by Lessee (or if any Permitted Sublease is then in effect,
            any Permitted Sublessee) subject to a conditional sale or other
            security agreement under circumstances where neither Section
            7.8(b)(ii) nor Section 7.8(b)(iii) is applicable, provided that such
            installation shall be deemed an Event of Loss with respect to such
            Engine and Lessee shall (or shall cause any Permitted Sublessee to)
            comply with Section 10.2 hereof in respect thereof.

             (c) The rights of any Permitted Sublessee or other transferee who
      receives possession by reason of a transfer permitted by this Section or
      Section 13 hereof, other than the transfer of an Engine which is deemed an
      Event of Loss, shall be and shall be deemed to be effectively subject and
      subordinate to, and any Permitted Sublease permitted by this Section or
      Section 13 hereof shall be effectively and expressly subject and
      subordinate to, all the terms of this Lease, including, without
      limitation, Lessor's rights to repossession and to avoid such Permitted
      Sublease upon such repossession. The terms of such Permitted Sublease
      shall not permit any Permitted Sublessee to take any action not permitted
      to be taken by Lessee under this Lease. Lessee shall remain primarily
      liable hereunder for the performance of all of the terms and conditions of
      this Lease to the same extent as if such Permitted Sublease had not
      occurred. No pooling agreement, interchange agreement, Permitted Sublease
      or other relinquishment of possession of the Airframe or any Engine or
      part shall in any way discharge or diminish any of Lessee's obligations to
      Lessor hereunder or constitute a waiver of Lessor's rights or remedies
      hereunder. All necessary action shall be taken by Lessee at its expense
      which is required in connection with any Permitted Sublease to continue
      the perfection of the right, title and interest of Lessor in the Aircraft,
      the Airframe and the Engines and Lessor's rights under the Lease, and such
      Permitted Sublease and all other actions necessary or required to preserve
      the right, title and interest of Lessor in the Aircraft, Airframe and
      Engines. Notwithstanding any provision herein to the contrary, no
      Permitted Sublease permitted pursuant to this Section or Section 13 shall
      permit any further sub-subleasing of the Aircraft.

      7.9. INSIGNIA. Lessee agrees to maintain (or cause to be maintained) in a
convenient location in the cockpit of the Airframe a nameplate setting forth the
name of Lessor and its status as owner/lessor of the Aircraft. Such nameplate
shall be replaced, if necessary, with a nameplate reflecting the name of any
successor Lessor, as permitted in this Agreement. Except as above provided,
Lessee will not allow the name of any Person to be placed on an Airframe as a
designation that might be interpreted as a claim of ownership; provided that
nothing herein contained shall prohibit Lessee (or any Permitted Sublessee) from
placing its customary colors and insignia on the Airframe.

                                      20
<Page>

      7.10. INSPECTIONS BY LESSOR. Not more than once annually during the Term,
Lessor or its authorized representatives may upon at least 15 days' prior notice
to Lessee (unless an Event of Default has occurred and continuing, in which
event, Lessor may exercise its rights under this Section 7.10 as often as it
deems necessary upon one Business Day's prior notice) and at a time and place
reasonably acceptable to Lessee, at its own expense and risk, conduct a visual
walk-around inspection of the Aircraft and any Engines, which shall not include
opening any panels or bays and may inspect the Manuals and Technical Records
relating to the operation and maintenance thereof (which Lessee shall provide
copies of to Lessor upon Lessor's reasonable request), provided that (a) any
such inspection shall be subject to the safety, security and workplace rules
applicable at the location where such inspection is conducted and any applicable
governmental rules or regulations, (b) in the case of an inspection during a
maintenance visit, such inspection shall not interfere with the normal conduct
of such maintenance visit or extend the time required for such maintenance visit
or, in any event, at any time interfere with the use or operation of the
Airframe or any Engine or with the normal conduct of Lessee's or a Permitted
Sublessee's business (provided further, that in no event shall this provision
adversely affect Lessor's right to inspect the Aircraft at least once annually
during the Term), and (c) Lessor shall not be required to undertake or incur any
additional liabilities in connection with any such inspection. All information
obtained in connection with any such inspection shall be held confidential by
Lessor, except as may be required by an order of any court or administrative
agency or by any statute, rule, regulation or order of any governmental
authority or as may be necessary to enforce the terms of this Lease. If
requested by Lessor, Lessee shall provide, or shall cause any Permitted
Sublessee to provide, the date (if then scheduled) upon which the Airframe
undergoes its next scheduled major check and shall advise Lessor of the name and
location (if then known) of the relevant maintenance performer.

SECTION 8. RETURN OF THE AIRCRAFT.

      8.1. RETURN. Upon the termination of this Lease at the end of the Term
(unless there has been an Event of Loss with respect to the Aircraft or unless
Lessee exercises its option to purchase the Aircraft or upon Lessor's exercise
of its remedies pursuant to Section 15), Lessee shall, at its own cost and
expense, return the Aircraft to Lessor at a location in the continental United
States on Lessee's regional jet route system where Lessee has appropriate
maintenance and repair facilities specified by Lessor (the "Return Location") in
compliance with the provisions of this Section 8. At the time of its return, the
Aircraft shall be free and clear of all Liens, other than Lessor Liens, and
Lessor and Lessee shall execute a return acceptance certificate (the "Return
Acceptance Certificate") in substantially the form attached hereto as Exhibit F.
Lessee shall execute and deliver to Lessor such instruments of release and
termination of this Lease as to the Aircraft, in form suitable for recording at
FAA and other public offices, as Lessor may reasonably request in order to make
clear upon public records that the Aircraft is free and clear of all rights of
Lessee therein, and shall authorize Lessor to date such instruments with the
effective date of expiration or earlier cancellation or termination of the Term
of this Lease as to the Aircraft.

      8.2. RETURN OF OTHER ENGINES. In the event that any engine not owned by
Lessor and leased to Lessee hereunder shall be delivered with the returned
Airframe (a "Replacement

                                      21
<Page>

Engine"), Lessee shall, concurrently with such delivery, at no cost to Lessor,
furnish, or cause to be furnished, to Lessor a full warranty (as to title) bill
of sale with respect to each such Replacement Engine, in form and substance
reasonably satisfactory to Lessor, and shall take such other action as Lessor
may reasonably request with respect to the transfer of title thereof to Lessor.
Upon transfer of title to Lessor, such Replacement Engine shall be deemed to be
an Engine for all purposes hereof and thereupon Lessor will transfer to Lessee,
without any representation, warranty or recourse of any kind whatsoever, express
or implied, except a warranty as to the absence of Lessor's Liens, all of
Lessor's right, title, and interest in and to any Engine not installed on such
Airframe at the time of the return thereof. A Replacement Engine shall be the
same or improved make and model as the Engines and, in any event, both engines
on the returned Airframe shall be of the same make and model. Any engine
returned shall meet the requirements set forth in Section 8.10, and shall be in
the same or better condition and have the same or greater remaining value,
utility and useful life as the replaced Engine, assuming that the replaced
Engine was in such condition and repair and of the value, utility and useful
life as required by this Lease.

      8.3. CONDITION OF THE AIRCRAFT. The Aircraft at the time of return to
Lessor shall have been maintained and repaired in accordance with the
Maintenance Program and this Lease, shall be in as good operating condition and
appearance as when delivered, with all of the Aircraft equipment, components and
systems functioning in accordance with their intended use, taking due account in
each case of ordinary wear and tear, with no obvious damage. The Airframe shall
satisfy the following conditions: if the C Check (or its then equivalent) is
performed in segments, Lessee shall complete the next segment check within 100
Flight Hours prior to return and shall rectify all Discrepancies revealed by
such check. If the Airframe is not on a segmented maintenance program, it shall
have not less than the lesser of (i) one-half time, or (ii) 2,000 Flight Hours
or 12 months, whichever is applicable, remaining until the next scheduled
structural inspection. Upon return of the Aircraft, all on-condition and
condition-monitored components shall be serviceable. Each applicable Airframe
component shall have remaining not less than the lesser of (i) one-half time, or
(ii) 12 months.

      8.4. REGISTRATION AND CERTIFICATION OF THE AIRCRAFT. Lessee will, unless
otherwise requested by Lessor in writing at least 30 days prior to expiration of
the Term, cause the Aircraft (including for this purpose any engines installed
on the Airframe which are not Engines), if it is not then so registered, to be
registered under the laws of the United States with the Federal Aviation
Administration in the name of Lessor or its designee. In addition, the Aircraft
shall have a valid Certificate of Airworthiness issued by the Federal Aviation
Administration permitting use of the Aircraft in commercial passenger service,
and shall have been continuously maintained in compliance with the Lease and
shall comply with the provisions of Federal Aviation Regulations, and all
applicable noise, corrosion, environmental and aging aircraft requirements. If
the Aircraft, with the prior written consent of Lessor, was not on an
FAA-approved maintenance program immediately prior to its return hereunder,
Lessee shall perform prior to the return of the Aircraft, at Lessee's cost and
expense, all work necessary, if any, to bridge the Aircraft onto a maintenance
program approved by the FAA so as to permit operation of the Aircraft under the
Federal Aviation Regulations.

                                     22
<Page>

      8.5. OVERHAUL, REPAIRS, MODIFICATIONS; COMPLIANCE WITH GOVERNMENTAL
REQUIREMENTS.

      (a) The Aircraft shall be properly documented to have been repaired or
overhauled by certified repair stations acceptable to the FAA and in such a
manner so that the Aircraft is approved by the FAA for use in the United States.
All major repairs performed since the Aircraft was delivered to Lessee by the
Manufacturer and which still exist on the Aircraft, must be immediately eligible
to receive approval by the FAA (or a designee of the FAA), if so required. All
data and documentation necessary to substantiate their certification, approval,
and methods of compliance, as required, shall accompany all such repairs. All
modifications performed since the Delivery Date which deviate from the certified
configuration and which still exist on the Aircraft shall have approval by the
FAA (or a designee of the FAA) or certification if so required. Complete data
and documentation necessary to substantiate their certification and approval and
methods of compliance shall accompany all such modifications.

      (b) The Aircraft shall, at Lessee's cost and expense, be in compliance
with all amendments or changes to the Federal Aviation Regulations and
Airworthiness Directives applicable to the Airframe, the Engines (or Replacement
Engines) or Parts accomplished by terminating action in compliance with the
issuing agency's or manufacturer's specific instructions, as the case may be, to
the extent that such Regulations or Directives have an effective date for
terminating compliance on or before the date of return or within 60 days
thereafter. In addition to the foregoing, if Lessor by prior written consent
allows the Aircraft to be registered under the laws of another jurisdiction, the
Aircraft shall, at Lessee's expense, (i) be in compliance with all Airworthiness
Directives and standards of the aviation authority of such jurisdiction, and
(ii) be in such physical condition, and accompanied by such documents and
certificates (including, without limitation, any export airworthiness
certificate), as may be required in order for the Aircraft to be eligible to be
registered under the Transportation Act without expense to Lessor.

      8.6. DEFERRED MAINTENANCE. Lessee agrees that it will not defer
maintenance or service, scheduled or unscheduled, with respect to the Aircraft
in contemplation of return of the Aircraft and will maintain the Aircraft in
accordance with the Maintenance Program; provided, however, that the Aircraft
shall have no deferred maintenance items, inspection items or placards. Items
deferred because of maintenance concessions (I.E., an exemption to operate
beyond the normal limits by monitoring) shall be brought up-to-date as if such
maintenance concessions or exemptions did not exist. Components whose time
status exceed the conditions or requirements imposed by this Lease shall be
brought into compliance with such conditions or requirements.

      8.7. CONFIGURATION. The Aircraft shall be returned in full passenger
seating configuration. In the event that the then-current seating configuration
has fewer seats than the seating configuration on the Delivery Date, Lessee
shall also deliver any remaining seats to Lessor. Installed seats shall be fully
serviceable and seat covers and other soft furnishings shall be in good
condition.

      8.8. AIRCRAFT INTERIOR. The interiors and exteriors of the Aircraft shall
be clean in

                                      23
<Page>

accordance with U.S. commuter air carrier industry standards.

      8.9. FUEL AND OIL. All fuel and oil on board the Aircraft shall be the
property of Lessor without charge.

      8.10. ENGINE CONDITION.

      (a) Upon return of the Aircraft, the Engines shall be in good operating
and serviceable condition and ready for flight with all equipment, accessories
and systems fully functional and operating within in-service limits and
guidelines established by the relevant manufacturers, including any equipment,
accessories or systems which would not otherwise be functioning due to an
authorized deviation or variation. If the Maintenance Program for major
overhauls and hot section inspections for the Engines is based on engine
condition trend monitoring in accordance with the engine manufacturer's or an
FAA-approved trend monitoring program, each Engine (or other engine returned
with the Airframe) shall have satisfactorily completed, immediately prior to
return, any boroscope inspection required under the trend monitoring program,
and Lessee shall provide all trend data for each Engine (or other engine
returned with the Airframe). If the boroscope inspection and the trend data
indicate that any action (other than inspection and monitoring) should be taken
in order to prevent serious engine deterioration or engine damage, Lessee shall
complete or cause to be completed at its sole cost and expense all such action
required, prior to return.

      (b) If the Maintenance Program is not based on engine condition trend
monitoring, the Engines shall have individually 2,000 Flight Hours and in the
aggregate 6,000 Flight Hours until scheduled overhaul, based upon the
Maintenance Program at the time of return.

      (c) If, at the time of return, the Engines are subject to a
Power-By-The-Hour Agreement under which Lessee (or Permitted Sublessee) is
current on all payments and otherwise in good standing, in lieu of the foregoing
requirements, Lessee shall return each Engine in such condition as shall make it
eligible for continuous maintenance under a Power-By-The-Hour Agreement, in the
hands of any U.S. air carrier. A "Power-By-The-Hour Agreement" is an engine
maintenance program provided by the Engines' manufacturer or one of its
affiliates or by another responsible maintenance provider, providing full
maintenance (other than routine day-to-day maintenance; provided, that
foreign-object damage, life-limited parts, line replacement units and abuse may
be excluded or separately charged) for the Engines at no cost other than
standard per-Cycle rates (I.E., excluding charges based on the current
maintenance status of the Engines), all benefits of which program are generally
available to qualifying U.S. air carriers.

      8.11. INSPECTION.

      (a) During the last three months of the Term, with not less than five days
prior notice, Lessee will cooperate, in all reasonable respects, with the
efforts of Lessor to sell or lease the Aircraft, including, without limitation,
permitting prospective purchasers or lessees to inspect the Aircraft and the
records relating thereto at reasonable times, provided that such cooperation
shall not interfere with the normal operation of the Aircraft by Lessee or any
Permitted Sublessee.

                                      24
<Page>

      (b) Immediately prior to the redelivery of the Aircraft, Lessee will make
the Aircraft and the Manuals and Technical Records available to Lessor at a
mutually-agreeable location for inspection by Lessor in order to verify that the
Aircraft complies with the Lease. Lessee shall make available to Lessor at the
Return Location, not less than ten days prior to the redelivery of the Aircraft,
such documentation regarding the condition, use, maintenance, operation and
history of the Aircraft during the Term of the Lease as Lessor may reasonably
request. Except in regard to the costs associated with Lessee's personnel, the
inspection shall be at Lessor's cost and expense.

      8.12. OPERATIONAL GROUND CHECK. Prior to the return of the Aircraft to
Lessor hereunder, Lessee shall, at its cost and expense, conduct an operational
ground check in accordance with the requirements of the Manufacturers, the
Maintenance Program and this Lease, and shall promptly correct any Discrepancies
at Lessee's cost and expense.

      8.13. OPERATIONAL CHECK FLIGHT. Promptly after completion of all
corrections required under Section 8, the Aircraft shall be check flown by
Lessee at its cost and expense, using qualified flight personnel, for the
purpose of demonstrating to lessor compliance with the requirements of this
Lease and the satisfactory operation of the Aircraft and its equipment and
systems. Two of Lessor's employees or representatives may participate in such
flight as observers. Lessee's pilot shall be in command of the Aircraft. Such
flight shall be flown using the Manufacturer's operational check flight
procedures sufficient to demonstrate the proper operation of all systems for
normal passenger use and compliance with the requirements of this Lease. Upon
completion of such operational check flight, Lessor shall set forth in writing
any Discrepancies required to be corrected by Lessee in order to comply with
provisions of this Section 8, and Lessee shall promptly correct or cause to be
corrected at Lessee's cost and expense any such Discrepancies. Lessee shall
provide for such additional test flights as are necessary to demonstrate that
any Discrepancies identified on prior test flights have been corrected. If any
of the Discrepancies referred to in Section 8.12 or this Section 8.13 continues
to persist, Lessor may (but shall not be obligated to) accept return of the
Aircraft and apply the procedure set forth in Section 8.15 for such
Discrepancies.

      8.14. ACCEPTANCE. Unless otherwise mutually agreed, the operational check
flight(s) shall take place at the Return Location. Upon satisfactory completion
of the operational check flight(s), and after Lessee has corrected the
Discrepancies as required to comply with this Section 8 or, in the discretion of
Lessor, pursuant to the last sentence of Section 8.13, the Aircraft shall be
technically accepted by Lessor's representatives at the Return Location. Such
technical acceptance shall be evidenced by the execution and delivery of a
return acceptance certificate in substantially the form of Exhibit F hereto.
Subject to Section 8.15, Lessor hereby agrees that such acceptance of the
Aircraft by Lessor or Lessor's representatives shall, without further act,
irrevocably constitute acceptance of the redelivery of the Aircraft.

      8.15. DEFERRED DISCREPANCY CORRECTION. Any Discrepancies identified during
the inspection, operational ground checks and operational check flight(s)
referred to in Sections 8.11, 8.12 and 8.13 which were not corrected by Lessee
prior to the acceptance of the Aircraft by Lessor pursuant to Section 8.14 shall
be corrected by Lessee at Lessee's cost and expense or, at

                                      25
<Page>

Lessor's option, may be corrected by Lessor or its designee after return of
the Aircraft and Lessee shall reimburse Lessor for all reasonable costs and
expenses incurred by Lessor or its designee for accomplishing such
Discrepancy corrections. Lessee shall, not later than 30 days after the date
of Lessor's invoice, pay Lessor for all such costs and expenses.

      8.16. MANUALS AND TECHNICAL RECORDS. Lessee shall deliver or cause to be
delivered to Lessor, at the time the Aircraft is returned to lessor, all of the
Manuals and Technical Records, inspection, modification, maintenance and
overhaul records, updated and maintained by Lessee through the date of return of
the Aircraft as required by the FAA and the Maintenance Program. Such Manuals
and Technical Records and other records shall be sufficient to establish and
certify that the Aircraft has been maintained on an FAA-approved maintenance
program. If hard (non-computerized) copies of the Manuals and Technical Records
are not available, Lessee shall provide records maintained in accordance with
alternate methods approved by the FAA. In addition, Lessee shall also provide
Lessor, at the time the Aircraft is returned to Lessor, all records, documents,
manuals, authorizations, drawings and data in English which were developed or
caused to be developed by Lessee and/or required to be maintained with respect
thereto under applicable rules and regulations of each country under the laws of
which the Aircraft has been registered or to which the Aircraft was otherwise
subject during the Term. If any Manuals and Technical Records are missing,
incomplete, or otherwise not in accordance with FAA standards and requirements,
Lessee shall re-accomplish the maintenance tasks necessary to produce such
Manuals and Technical Records in accordance with the Maintenance Program prior
to delivery of the Aircraft or otherwise perform all necessary acts (without
regard to applicable waivers or deferrals) to obtain or recreate such Manuals
and Technical Records in a manner satisfactory to the FAA. All life-limited
Parts shall have full documentation necessary to trace compliance with the
Maintenance Program and FAA requirements throughout the Term. All Manuals and
Technical Records shall be in English and shall be made available upon request
by Lessor for review at the central maintenance record facility for aircraft of
the same type a minimum of 15 Business Days prior to the required date of
Aircraft delivery to Lessor.

      8.17. SERVICE BULLETIN KITS. All vendors and manufacturers Service
Bulletin Kits for the Aircraft obtained by Lessee (or, if a Permitted Sublease
is then in effect, any Permitted Sublessee) free of charge but not installed
therein shall be returned with the Aircraft, as part of the Aircraft at the time
of return.

      8.18. LESSEE'S SPECIAL EXTERIOR MARKINGS. At the time of the return of the
Aircraft, Lessee shall, at its cost and expense, shall have all of Lessee's and
any Permitted Sublessee's special exterior markings and insignia removed or
painted over, and the areas where such markings have been removed or painted
over refurbished as necessary to blend with adjacent areas; provided that the
FAA registration number shall not be removed from the Aircraft. in the event
that, notwithstanding Lessee's obligation to do so, Lessee does not remove such
markings, Lessor shall have the right to do so at Lessee's cost and expense, but
Lessor shall have no obligation to remove such markings prior to the sale,
lease, or other disposition of the Aircraft by Lessor after its return.

      8.19. OWNERSHIP.  Any documents, equipment and any other items returned to
Lessor

                                      26
<Page>

pursuant to this Section 8 which are not already owned by Lessor shall thereupon
become the property of Lessor.

            8.20. EQUIVALENCY CHARGE. Failure to comply with the above standards
relating to average time or average cycles, if then applicable, with respect to
the Aircraft or Engines shall result in a compensating payment by Lessee equal
to the value of such Discrepancy, net of the value to the extent that any of the
foregoing standards is exceeded with respect to the Aircraft or Engines (such
value to be based on the then-current estimated third-party cost to Lessee of
the overhaul involved to meet such standards); provided, however, that for
purposes of determining the value of any components that exceed such standards,
no credit shall be given to Lessee for any major components with less than 25%
life remaining at return.

      8.21. DISPUTES REGARDING RETURN CONDITION. Any dispute between Lessor and
Lessee regarding the condition of the Airframe or any Engine arising under this
Section 8 shall be referred to an aviation auditing firm selected by Lessor and
Lessee. Lessee shall bear the cost of such aviation auditing firm. The parties
will use their best efforts to obtain a final resolution of the dispute under
the foregoing procedures within 30 days following the date on which the dispute
arises.

      8.22. STORAGE. Following return of the Aircraft, Lessee shall, at Lessor's
written request, assist Lessor in arranging storage for the Aircraft (which may
be outdoors) at the Return Location for a period not exceeding 60 days. Such
storage shall be at Lessor's sole cost and expense (not to exceed Lessee's
actual cost); provided, however, that if such termination occurs as a result of
an Event of Default, such storage shall be at Lessee's cost. Lessor shall, at
its sole cost and expense, maintain in effect during such storage period
insurance covering the Aircraft, in such amounts and against such risks as would
be customarily carried in similar circumstances by a reasonably prudent Lessor;
provided, however, that if such termination occurs as a result of an Event of
Default, Lessee shall reimburse Lessor upon demand for the cost of such
insurance and shall [co-operate] COOPERATE with Lessor in obtaining such
insurance.

SECTION 9. LIENS.

      9.1. Lessee (or, if any Permitted Sublease is in effect, any Permitted
Sublessee) will not directly or indirectly create, incur, assume or suffer to
exist any Lien on or with respect to the Aircraft, any Engine, any Part, title
thereto or any interest therein or in this Lease, except (i) the rights of
Lessor as owner of the Aircraft, (ii) the respective rights of Lessor and Lessee
as provided herein, (iii) the rights of others under agreements or arrangements
to the extent permitted by the terms of Section 7.5 and Section 7.8(b)(iii)
hereof, (iv) Lessor Liens, (v) Liens for Taxes of Lessee (or, if any Permitted
Sublease is then in effect, any Permitted Sublessee) either not yet due or being
contested in good faith by appropriate proceedings so long as such proceedings
do not involve any material danger of the sale, forfeiture, loss or loss of use
of the Airframe, or any Engine or an interest therein, or any risk of material
liability (other than for the Taxes being contested), or any risk of civil or
criminal penalties being imposed on any Indemnitee, (vi) materialmen's,
mechanic's, workmen's, repairmen's, employees, or other like liens arising in
the ordinary course of Lessee's (or, if a Permitted Sublease is then in effect,

                                      27
<Page>

Permitted Sublessee's) business (including those arising under maintenance
agreements entered into in the ordinary course of business) securing obligations
that are not overdue or are being contested in good faith by appropriate
proceedings so long as such proceedings do not involve any material danger of
the sale, forfeiture, loss or loss of use of the Airframe or any Engine or any
interest therein, or any risk of material liability (other than for payment of
the amount being contested), or any risk of civil or criminal penalties being
imposed on any Indemnitee, (vii) Liens arising out of any judgment or award
against Lessee (or, if any Permitted Sublease is then in effect, any Permitted
Sublessee), unless the judgment secured shall not, within 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 30 days after the expiration of such stay, and (viii) any Lien with
respect to which Lessee (or, if any Permitted Sublease is then in effect, any
Permitted Sublessee) shall have provided a bond adequate in the reasonable
opinion of Lessor. Lessee will promptly, at its own expense, take (or cause to
be taken) such actions as may be necessary duly to discharge any such Lien not
excepted above if the same shall arise at any time.

SECTION 10. LOSS, DESTRUCTION, REQUISITION, ETC.

      10.1. EVENT OF LOSS WITH RESPECT TO THE AIRCRAFT.

      (a) Upon the occurrence of an Event of Loss with respect to the Airframe
or the Airframe and the Engines and/or engines then installed thereon, Lessee
shall promptly, and in any event, within 15 Business Days after such occurrence,
give Lessor written notice of such Event of Loss. After an Event of Loss and
until receipt by Lessor of the Stipulated Loss Value and all other amounts due
under the Lease, Lessee shall continue to pay Basic Rent and the parties shall
perform all of their other obligations under the Lease that remain possible of
performance taking into consideration the Event of Loss. Lessee shall, within 45
days after such occurrence, give Lessor written notice of its election to
perform one of the following options (it being agreed that if Lessee has not
have given Lessor notice of such election, Lessee shall be deemed to have
elected the option described in clause (ii) below:

10(c), on a date not more than 150 days after the occurrence of the Event of
Loss (or, if earlier, the last day of the Term), convey or cause to be conveyed
to Lessor, and to be leased by Lessee hereunder in replacement of the Airframe
and Engines with respect to which the Event of Loss occurred, a Replacement
Airframe (together with the same number of Replacement Engines as the number of
Engines, if any, which were subject to such Event of Loss), such Replacement
Airframe and Replacement Engines to be free and clear of all Liens except
Permitted Liens and to have a remaining useful life, estimated residual value,
value and utility at least equal to the Airframe and Engines, if any, so
replaced (assuming that such Airframe and Engines were in the condition and
repair required by the terms hereof) and to be an airframe that is the same make
and model and same or later vintage as the Airframe to be replaced thereby, or
an improved make and model; provided that, if Lessee has not performed its
obligation to effect such replacement under this clause (i) during the 150-day
period provided herein (or, if earlier, the last day of the Term), it shall give
Lessor notice to such effect upon or before the expiration of such period and
shall

                                      28

promptly pay on the 30th day after the date of such notice to Lessor (or, if
earlier, the last day of the Term), in immediately-available funds, the amount
specified in clause (ii) below; or

      (ii) pay to Lessor on the earlier to occur of the third Business Day
following the date of receipt of insurance proceeds in respect of the Event of
Loss or 120 days following the date of the Event of Loss, the sum of (i) any
amounts then accrued under this Lease (including Basic Rent due and payable
hereunder), plus (ii) the Stipulated Loss Value of the Aircraft computed as of
the Rent Payment Date next following the date on which the Event of Loss
occurred, plus (iii) any Supplemental Rent and other amounts otherwise due and
payable hereunder plus (iv) any reasonable expenses and costs incurred in
connection with such Event of Loss by Lessor, minus (v) any prepaid rent
attributable to the period following the date of such payment.

      (b) In the event that Lessee has provided a Replacement Aircraft as
provided in Section 10(a)(i) hereof, (i) this Lease shall continue with respect
to such Replacement Aircraft as though no Event of Loss had occurred; (ii)
Lessor shall, at the expense of Lessee, convey to Lessee "as-is, where-is",
without recourse or warranty except for a warranty against Lessor's Liens, all
right, title and interest of Lessor in and to the Airframe and the Engine or
Engines, if any, installed on the Airframe upon the occurrence of the Event of
Loss by executing and delivering to Lessee such bills of sale and other
documents and instruments as Lessee may reasonably request to evidence such
conveyance; (iii) Lessor shall, at the request and expense of Lessee, to the
extent assignable, assign to Lessee all claims it may have against any other
Person arising from the Event of Loss; and (iv) Lessee shall be entitled to
receive all insurance proceeds and proceeds from any award in respect of
condemnation, confiscation, seizure or requisition, including any interest
thereon, to the extent not previously applied to the purchase price of the
Replacement Aircraft.

      (c) Lessee's right to substitute a Replacement Aircraft as provided in
Section 10(a)(i) shall be subject to the fulfillment, as Lessee's sole cost and
expense, in addition to the conditions continued in Section 10(a)(i), of the
following conditions precedent:

            (i) On the date of delivery of the Replacement Aircraft to Lessor
(such date being referred to in this Section 10(c) as the "Replacement Closing
Date"), no Event of Default shall have occurred and be continuing;

            (ii) On the Replacement Closing Date, the following documents shall
have been duly authorized, executed and delivered by the respective party or
parties thereto and shall be in full force and effect, and an executed
counterpart of each such document (or, in the case of the FAA Bill of Sale, a
photocopy thereof) shall have been delivered to Lessor:

      (A) a Lease Supplement covering the Replacement Aircraft, which has been
duly filed for recordation with the FAA;

      (B) an FAA Bill of Sale covering the Replacement Aircraft, executed by the
owner thereof in favor of Lessor, and dated the Replacement Closing Date;

Lessor, covering the Replacement Aircraft, executed by the owner thereof in
favor of Lessor, dated the Replacement Closing Date;

      (D) an assignment of manufacturer's and vendor's warranties with respect
to the Replacement Aircraft;

            (iii) On or before the Replacement Closing Date, Lessor shall have
received such documents and evidence with respect to Lessee (including, without
limitation, a certificate of a Responsible Officer regarding the particulars of
the Replacement Aircraft and its compliance with the terms of this Lease), or
the owner of the Replacement Aircraft, as Lessor may reasonably request in order
to establish the consummation of the transaction contemplated by Section
10(a)(i) and this Section 10(c), the taking of all necessary corporate action in
connection therewith and compliance with the conditions set forth in this
Section 10(c), in each case in form and substance reasonably satisfactory to
Lessor;

            (iv) Lessor shall have received satisfactory evidence as to the

Replacement Aircraft is free and clear of all Liens, (x) the bill of sale
referred to in Section 10(c)(ii)(C) constitutes an effective instrument for
conveying title to the Replacement Airframe and Replacement Engines, if any, to
Lessor, (y) all documents executed and delivered by Lessee pursuant to this
Section 10(c) have been duly authorized executed and delivered by Lessee and
constitute legal, valid and binding obligations of, and are enforceable against,
Lessee in accordance with their respective terms and no further action is
necessary or advisable in order to establish and perfect the title of Lessor in
the Replacement Aircraft, and (z) Lessor is entitled to the benefits of 11
U.S.C. Section 1110 with respect to such Replacement Aircraft to the same extent
as with respect to the replaced Aircraft immediately preceding such replacement;
and (B) an opinion of qualified FAA counsel (or counsel in such jurisdiction
outside of the United States where the Aircraft may be registered) as to, in the
case of FAA counsel, the due recordation of the Lease Supplement and all other
documents or instruments the recordation of which is necessary to perfect and

satisfactory to the Lessor, to

                                      30
<Page>

effect that there are no adverse tax consequences resulting from such
replacement (and Lessor shall use its best efforts to cause such a timely
opinion to be delivered) or (2) Lessee shall have provided, or caused to be
provided, an indemnity in respect of any adverse tax consequences in form and
substance satisfactory to Lessee.

      10.2. TERMINATION UPON PAYMENT. At such time as Lessor shall have received
the sum of the amounts specified Section 10.1(a)(ii) hereof, (a) the obligation
of Lessee to pay succeeding installments of Basic Rent shall cease to accrue,
(b) the Term shall terminate, (c) Lessor will transfer to or at the direction of
Lessee (or, if any Permitted Sublease is then in effect, any Permitted
Sublessee), without recourse or warranty (except as to the absence of Lessor
Liens), all of Lessor's right, title and interest in and to the Airframe and any
Engines subject to such Event of Loss, as well as any Engines not subject to
such Event of Loss, and furnish to or at the direction of Lessee (or, if any
Permitted Sublease is then in effect, any Permitted Sublessee) a warranty bill
of sale and an FAA bill of sale evidencing such transfer, and (d) Lessee (or, if
any Permitted Sublease is then in effect, any Permitted Sublessee) shall be
subrogated to all claims of Lessor, if any, against third parties, for damage to
or loss of the Airframe and any Engines which were subject to such Event of
Loss.

      10.3. EVENT OF LOSS WITH RESPECT TO AN ENGINE. Upon the occurrence of an
Event of Loss with respect to an Engine under circumstances not involving an
Event of Loss with respect to an Airframe, Lessee (or, if any Permitted Sublease
is then in effect, any Permitted Sublessee) shall promptly (and in any event,
not later than 15 days after such occurrence) give Lessor written notice thereof
and shall, within 60 days after the occurrence of such Event of Loss, convey or
cause to be conveyed to Lessor as replacement for the Engine with respect to
which such Event of Loss occurred, title to another engine of the same or
improved type as the Engine (or an equivalent or improved engine of the same
manufacturer and suitable for installation and use on the Airframe and
compatible with the other Engine(s) leased hereunder) free and clear of all
Liens (other than Permitted Liens, which engine may upon its transfer to Lessor
become subject to any and all Permitted Liens) and having (if no Event of
Default has occurred and is continuing) without regard to Cycles) a value,
utility and remaining economic useful life at least equal to the Engine with
respect to which such Event of Loss occurred (assuming that such Engine was of
the value, utility and useful life and in such condition and repair as required
by the terms of this Lease immediately prior to such Event of Loss). Prior to
any such conveyance, Lessee (or, if any Permitted Sublease is then in effect,
any Permitted Sublessee), shall, at its own expense, (a) furnish Lessor with a
full warranty bill of sale and a FAA bill of sale, in form and substance
reasonably satisfactory to Lessor, evidencing such transfer of title, (b) cause
a Lease Supplement to be duly executed by Lessee (or, if any Permitted Sublease
is then in effect, Permitted Sublessee) and filed for recording pursuant to the
Transportation Act or the applicable laws, rules and regulations of any other
jurisdiction in which the Airframe may then be registered, (c) furnish Lessor
with such evidence of compliance with the insurance provisions of Section 11
with respect to such substituted property as Lessor may reasonably request, (d)
provide an opinion in form and substance reasonably satisfactory to Lessor of
tax counsel reasonably satisfactory to Lessor to the effect that such
substitution will not result in any adverse tax consequences to Lessor, (e) at
Lessor's request, furnish an appraisal of an independent appraiser selected by
Lessor in form and substance reasonably satisfactory to Lessor evidencing

                                      31
<Page>

compliance with the requirements as to value, utility and remaining economic
useful life of the substitute engine, (f) provide opinions in form and substance
reasonably satisfactory to Lessor of counsel reasonably acceptable to Lessor to
the same effect as set forth in Section 10(c)(vii) hereof, and (g) assign to
Lessor the benefit of all assignable manufacturer's and vendor's warranties with
respect to the replacement engine. Lessor shall transfer to or at the direction
of Lessee without recourse or warranty, except as to absence of Lessor Liens,
all of Lessor's right, title and interest, if any, in and to (i) the Engine with
respect to which such Event of Loss occurred by furnishing to or at the
direction of Lessee a warranty bill of sale and an FAA bill of sale evidencing
such transfer and (ii) all claims, if any, against third parties, for damage to
or loss of the Engine subject to such Event of Loss, and such Engine shall
thereupon cease to be an Engine leased hereunder. For all purposes hereof, each
such replacement engine shall, after such conveyance, be deemed part of the
property leased hereunder, and shall be deemed an Engine. No Event of Loss with
respect to an Engine under the circumstances contemplated by the terms of this
Section 10.3 shall result in any reduction in Basic Rent.

      10.4. APPLICATION OF PAYMENTS FROM GOVERNMENTAL AUTHORITIES FOR
REQUISITION OF TITLE, ETC. Provided no Event of Default has occurred and is
continuing, any payments (other than insurance proceeds, the application of
which is provided for in Section 11) received at any time by Lessor or by Lessee
from any governmental authority or other person with respect to an Event of Loss
resulting from the theft, disappearance, condemnation, confiscation or seizure
of, or requisition of title to or use of, the Airframe or any Engine, other than
a requisition for use (but not of title) by the United States Government or
other government of registry of the Aircraft or under which the Aircraft is
based or any instrumentality or agency of any thereof not constituting an Event
of Loss, shall be applied as follows:

      (a)   If payments are received with respect to the Airframe (or the
            Airframe and any Engine or engines then installed thereon), (i) if
            such property has not been replaced pursuant to the provisions
            hereof, after reimbursement of Lessor for reasonable costs and
            expenses, so much of such payments remaining as shall not exceed the
            Stipulated Loss Value and other amounts required to be paid by
            Lessee to Lessor pursuant to Section 10.1 hereof shall be applied in
            reduction of Lessee's obligation to pay such Stipulated Loss Value
            and such other amounts, if not already paid by Lessee, or, if
            already paid by Lessee, shall be applied to reimburse Lessee for its
            payment of such Stipulated Loss Value and such other amounts, and
            the balance, if any, of such payments remaining thereafter shall be
            paid to Lessor; or (ii) if such property has been replaced pursuant
            to the provisions hereof, after reimbursement of Lessor for
            reasonable costs and expenses, such payments shall be paid over to,
            or retained by, Lessee, provided that Lessee shall have fully
            performed or concurrently therewith, shall perform, its obligations
            under Section 10.1 with respect to the Event of Loss; and

      (b)   If such payments are received with respect to an Engine under
            circumstances contemplated by Section 10.3 hereof, so much of such
            payments remaining after reimbursement of Lessor for reasonable
            costs and expenses shall be paid over to, or retained by, Lessee,
            provided that Lessee shall have fully performed, or

                                      32
<Page>

            concurrently therewith shall perform, its obligations under Section
            10.2 with respect to the Event of Loss for which such payments are
            made.

      (c)   If an Event of Default has occurred and is continuing, all payments
            shall be paid over to Lessor or held for the account of Lessor until
            such time as the Event of Default has been cured.

      10.5. REQUISITION FOR USE OF THE AIRCRAFT BY THE UNITED STATES GOVERNMENT
OR THE GOVERNMENT UNDER WHICH THE AIRCRAFT IS REGISTERED OR BASED. In the event
of the requisition for use of the Airframe and the Engines or engines installed
on the Airframe during the Term by the United States Government or any other
government under which the Aircraft is registered or based or any
instrumentality or agency of any thereof, Lessee shall notify Lessor of such
requisition, and all of Lessee's obligations under this Lease with respect to
the Aircraft shall continue to the same extent as if such requisition had not
occurred. All payments received by Lessor or Lessee from such government for the
use of such Airframe and Engines or engines during the Term shall be paid over
to, or retained by, Lessee (or, if directed by Lessee, any Permitted Sublessee);
and all payments received by Lessor or Lessee from such government for the use
of such Airframe and Engines or engines after the end of the Term shall be paid
over to, or retained by, Lessor.

      10.6. REQUISITION FOR USE OF AN ENGINE BY THE UNITED STATES GOVERNMENT OR
THE GOVERNMENT UNDER WHICH THE AIRCRAFT IS REGISTERED OR BASED. In the event of
the requisition for use of an Engine (but not an Airframe) by the United States
Government or any other government under which the Aircraft equipped with such
Engine is registered or based or any agency or instrumentality of any thereof,
Lessee shall replace such Engine hereunder by complying (or causing any
Permitted Sublessee to comply) with the terms of Section 10.3 to the same extent
as if an Event of Loss had occurred with respect thereto, and, upon compliance
with Section 10.3 hereof, any payments received by Lessor or Lessee from such
government with respect to such requisition shall be paid over to, or retained
by, Lessee.

      10.7. REPAIRABLE DAMAGE; USE OF INSURANCE PROCEEDS. In the event of
repairable damage to the Aircraft or any of the Engines, or of any Event of Loss
with respect to an Engine when no Event of Loss has occurred with respect to the
Airframe, Lessor shall forthwith, provided that no Event of Default has occurred
and is continuing, either pay any insurance proceeds received by it to Lessee
(or, if any Permitted Sublease is then in effect, any Permitted Sublessee) upon
Lessee's furnishing evidence to Lessor that such damage has been repaired in
accordance with the provisions of this Lease or is undergoing repair such that
the condition of the Aircraft shall be at least equivalent to its condition
immediately prior to the event of damage as if such event had not occurred, or,
in the case of an Event of Loss with respect to an Engine when no Event of Loss
has occurred with respect to the Airframe equipped with such Engine, utilize the
relevant insurance proceeds in the purchase of a Replacement Engine (or to
reimburse Lessee for amounts paid by Lessee to purchase a Replacement Engine, as
the case may be).

      warranty, declaration or condition contained in such policies;

            (c) provide that the insurers shall waive any right of subrogation

      Lessee in its capacity as sublessor under such Permitted Sublease);

            (d) provide that the liability of the insurers shall not be affected
      by any other insurance which may be available to or carried by Lessor (or

<Page>

      any such insurance lapses for any reason whatsoever, or if any material
      change is made in such insurance which adversely affects the interests of
      Lessor, such cancellation or change shall not be effective as to Lessor
      for thirty (30) days (seven (7) days or, if less, the longest period of
      time that is commercially available, in the case of war risk and allied
      perils coverage) after receipt by Lessor of written notice by such
      insurers;

            (k) shall expressly provide that all of the provisions thereof,
      except the limits of liability, shall operate in the same manner as if a

      set-off or counterclaim or any other deduction (whether by attachment or
      otherwise) in respect of any liability of or against Lessee or Lessor
      (including for the payment of premiums).

      11.3. APPLICATION OF HULL INSURANCE PROCEEDS. As between Lessor and
Lessee, any payments received by Lessor under policies of insurance required to
be maintained by Lessee pursuant to Sections 11.1(a) or (b), shall be applied as
follows provided no Event of Default has occurred and is continuing (for so long
as an Event of Default has occurred and is continuing, all payments shall be
held by Lessor as security for Lessee's obligations under this Lease and if
Lessor has exercised its remedies pursuant to Section 15 hereof, applied against
Lessee's obligations hereunder):

            (a) If such payments are received by Lessor with respect to loss or
      damage (including an Event of Loss with respect to an Engine) not
      constituting an Event of Loss with respect to an Airframe, so much of such
      payments remaining after reimbursement of Lessor for reasonable
      out-of-pocket costs and expenses shall be paid over to Lessee upon
      Lessee's performance of its repair or replacement obligations under this
      Lease pursuant to Section 10.7 hereof.

            (b) If such payments are received by Lessor with respect to an Event
      of Loss with respect to an Airframe, so much of such payments remaining
      after reimbursement of Lessor for reasonable out-of-pocket costs and
      expenses as shall not exceed the amount required to be paid by Lessee
      pursuant to Section 10.1 shall be applied in reduction of Lessee's
      obligation to pay such amount if not already paid by Lessee, and to
      reimburse Lessee if it shall have paid all or part of such amount, and the
      balance, if any, of such payments shall be paid over to Lessee.

            (c) If such payments are received with respect to an Airframe or an
      Airframe and Engines or engines installed on such Airframe and the
      Airframe has been or is being replaced by Lessee , so much of such
      payments remaining after reimbursement of Lessor for reasonable
      out-of-pocket costs and expenses shall be paid over to, Lessor, and upon

                                      36
<Page>

      completion of (or, if requested by Lessee, simultaneously with) such
      replacement be paid over to Lessee.

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

      11.5. REPORTS. Lessee shall furnish or cause to be furnished to Lessor not
later than the Delivery Date and at least annually thereafter on or before the
renewal dates of Lessee's (or, if any Permitted Sublease is then in effect,
Permitted Sublessee's) relevant insurance policies, a report signed by Lessee's
(or, if any Permitted Sublease is then in effect, Permitted Sublessee's)
independent firm of insurance brokers reasonably satisfactory to Lessor stating
the opinion of such firm that the insurance coverage then carried and maintained
on the Aircraft complies with the terms hereof and describing in reasonable
detail the insurance coverage then carried and maintained with respect to the
Aircraft. Lessee shall (and shall cause any Permitted Sublessee to) during the
Term furnish to Lessor evidence of renewal of the insurance policies required
pursuant to this Section 11 prior to the cancellation, lapse or expiration of
such insurance policies. Lessee shall cause its insurance brokers to advise
Lessor in writing promptly of any default in the payment of any premium and of
any other act or omission on the part of Lessee of which they have knowledge
which would in such firm's opinion invalidate or render unenforceable, in whole
or in any material part, any insurance on the Aircraft. Lessee shall also cause
the insurer to advise Lessor in writing at least 30 days prior to the
termination or cancellation of, or material adverse change in, such insurance
carried and maintained on the Aircraft pursuant to Section 11.1. In the event
that Lessee (or, if any Permitted Sublease is in effect, Permitted Sublessee)
fails to maintain or cause to be maintained insurance as herein provided, Lessor
may at its sole option, but shall be under no duty to, provide such insurance
and, in such event, Lessee shall, upon demand, reimburse Lessor, as Supplemental
Rent, for the cost thereof; provided, however, that no exercise by Lessor of
such option shall affect the provisions of this Lease, including the provisions
that failure by Lessee to maintain the required insurance shall constitute an
Event of Default.

      11.6. SELF-INSURANCE; DEDUCTIBLES. In addition to any applicable
deductible per aircraft that does not exceed industry standards for similar U.S.
airlines operating similar equipment under a program applicable to all aircraft
in Lessee's fleet, Lessee may self-insure by way of deductible, premium
adjustment or otherwise, but in no case shall the aggregate amount of
self-insurance with respect to public liability, property damage and all-risk
hull insurance exceed during any policy year, with respect to all of the
aircraft in the Lessee's fleet (including, without limitation, the Aircraft),
the lesser of (a) 50% of the highest replacement value of any one aircraft in
the Lessee's fleet or (b) $7 million, increased by any increase in the Consumer
Price Index All Urban Consumers - U.S. All Items from the date hereof through
the date of determination, using the base year immediately preceding the
Delivery Date.

SECTION 12. INDEMNITIES.

      12.1 GENERAL INDEMNIFICATION.

      (a) Lessee hereby assumes liability for, and does hereby agree, and shall
require any Permitted Sublessee or assignee to agree, to indemnify, protect,
save, defend, and hold harmless the Indemnitees from and against any and all
obligations, fees, liabilities, losses, damages, claims, demands, actions,
suits, judgments, costs and expenses, including reasonable legal expenses of
every kind and nature whatsoever (collectively, "Expenses") imposed on, incurred
or suffered by, or asserted against any Indemnitee, in any way relating to,
based on or arising out of:

            (i) this Lease and any other document entered into in connection
      with this Lease or any Permitted Sublease or transfer or any transactions
      contemplated hereby or thereby;

            (ii) the ordering, purchase, documentation, importation,
      exportation, acceptance or rejection, manufacture, construction, design,
      condition, modification, airworthiness, alteration, registration, fitness
      for use, merchantability, ownership, improvement, insuring, titling or
      retitling, registration or re-registration, licensing, financing,
      refinancing, delivery, non-delivery, control, transportation, testing,

      of the Aircraft, or any portion thereof (including the Airframe and each
      Engine or any engine used with the Airframe), or otherwise in connection
      with or with respect to the transactions contemplated by this Lease,
      whether or not such ordering, purchase, documentation, importation,
      exportation, acceptance or rejection, manufacture, construction, design,
      condition, modification, airworthiness, alteration, registration, fitness
      for use, merchantability, ownership, improving, insuring, titling or
      retitling, registration or re-registration, licensing, financing,
      refinancing, delivery, non-delivery, control, transportation, testing,
      overhaul, repair, imposition of any Lien, leasing, re-leasing, possession,
      use, operation, maintenance, location, storage, removal, replacement,
      return, sale, abandonment, any transfer of any kind or other disposition
      is in compliance with the terms of this Lease, including, without
      limitation, any of such as may arise from (i) loss or damage, loss or harm
      to any property or death of or injury to any person, (ii) patent or latent
      defects in the Aircraft or any portion thereof (whether or not
      discoverable), (iii) any claims based on strict liability in tort or
      otherwise, (iv) any claims based on patent, trademark or copyright
      infringement, and (v) any claims based on liability arising under any
      applicable environmental or noise or pollution control law or regulation;

            (iii) any breach or failure on the part of Lessee or any Permitted
      Sublessee to perform, observe or comply with any of the terms of this
      Lease, or the falsity or inaccuracy of any representation or warranty of
      Lessee under this Lease or any other instrument or agreement executed in
      connection with this Lease which falsity has a material and adverse effect
      on the Indemnitee; or

                                      38
<Page>

            (iv) the enforcement by Lessor of the terms of this Lease.

      (b) Lessee agrees that any payment or indemnity pursuant to this Section
12.1 in respect of any Expenses shall be in an amount which, after deduction of
all Taxes required to be paid by the 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, or any territory or possession of
the United States or any international authority, shall be equal to the excess,
if any, of (i) the amount of such Expense, over (ii) the net reduction in Taxes
required to be paid by such recipient by reason of the accrual or payment of
such Expense. For purposes of the foregoing, it shall be assumed that each
Indemnitee is subject to tax at the highest marginal rate imposed on or measured
by the income of corporations in each applicable taxing jurisdiction.

      (c) Lessee shall give each Indemnitee prompt notice of any occurrence,
event or condition known to Lessee as a consequence of which any Indemnitee may
be entitled to indemnification hereunder. Lessee shall forthwith upon demand of
any such Indemnitee reimburse such Indemnitee for reasonable expenses actually
incurred by it in connection with any of the foregoing or pay such amounts
directly.

      (d) Lessee shall be subrogated to an Indemnitee's rights in any matter
with respect to which Lessee has actually reimbursed such Indemnitee for amounts
expended by it or has actually paid such amounts directly pursuant to this
Section 12.1. Lessee shall not be entitled to exercise its subrogation rights
hereunder for so long as an Event of Default has occurred and is continuing
hereunder.

      (e) In case any action, suit or proceeding is brought against any
Indemnitee in connection with any Expense indemnified against hereunder, such
Indemnitee shall, promptly after receipt of notice of the commencement of such
action, suit or proceeding, notify Lessee thereof, enclosing a copy of all
papers served upon such Indemnitee; provided that the failure to provide such
notice shall not release Lessee from any of its obligations to indemnify
hereunder, except to the extent that such failure precludes Lessee's ability to
defend or resist such action. Lessee may, provided that Lessee has acknowledged
in writing its responsibility for such Expense hereunder, and upon such
Indemnitee's request shall, at Lessee's expense, resist and defend such action,
suit or proceeding, or cause the same to be resisted or defended by counsel
selected by Lessee and reasonably satisfactory to such Indemnitee (provided such
claim relates solely to one or more Expenses or can be severed from other
claims; if not, Lessee shall be consulted by such Indemmitee and be allowed, at
Lessee's sole cost and expense, to participate therein) and in the event of any
failure by Lessee to do so, Lessee shall pay all costs and expenses (including,
without limitation, reasonable legal expenses, including but not limited to
attorney's fees and expenses) incurred by such Indemnitee in connection with
such action, suit or proceeding.

      (f) Provided that no Event of Default has occurred and is continuing, no
Indemnitee shall enter into a settlement or other compromise with respect to any
Expense without the prior written consent of Lessee so long as (i) Lessee has
agreed in a writing acceptable to such Indemnitee that Lessee is liable to such
Indemnitee for such Expense hereunder, and (ii) Lessee

                                      39
<Page>

has provided such evidence, certifications and assurances as such Indemnitee may
reasonably request that Lessee has the ability to promptly pay any such Expense
in full.

      (g) Lessee's obligations under the indemnities provided for in this
Agreement shall be those of a primary obligor, whether or not the Person
indemnified shall also be indemnified with respect to the same matter under the
terms of any other document or instrument, and the Person seeking
indemnification from Lessee pursuant to any provision of this Agreement may
proceed directly against Lessee without first seeking to enforce any other right
of indemnification.

      (h) The obligations of Lessee under this Section 12.1 shall survive the
expiration or earlier termination of this Lease.

      12.2. EXCEPTIONS TO GENERAL INDEMNIFICATION. The indemnity provided for in
Section 12.1 shall not extend to Expenses of an Indemnitee arising out of or
resulting from, or which would not have been incurred but for, one or more of
the following:

                  (i) the inaccuracy or breach of any representation or warranty
            made by Lessor or the failure of Lessor to perform its obligations
            under this Lease;

                  (ii) the gross negligence or willful misconduct of such
            Indemnitee (other than gross negligence imputed to such Indemnitee
            solely by reason of its interest in the Aircraft or occurring as a
            result of Lessee's breach of its duties under this Lease or the
            Lease Supplement);

                  (iii) a voluntary disposition by Lessor of all or any part of
            its interest in the Aircraft, the Airframe or any Engine or Part or
            in this Lease other than pursuant to an exercise of remedies after
            an Event of Default has occurred and is continuing;

                  (iv) acts or events that occurred or failed to occur prior to
            the Delivery Date or after the expiration of the Term and the return
            of possession of the Aircraft to Lessor in accordance with the terms
            of Section 8;

                  (v) the failure of any Indemnitee to comply with any covenant,
            or the breach of any covenant made by an Indemnitee;

                  (vi) expenses which relate to a Lessor Lien or other Lien;

                  (vii) any Taxes, it being understood that Lessee's liability
            for Taxes (other than the gross-up provided in Section 12.1) of an
            Indemnitee shall be as set forth in Section 12.3; or

                  (viii) costs or expenses which under the express terms of this
            Lease are required to be paid by Lessor or its transferees.

      12.3  GENERAL TAX INDEMNITY.

                                      40
<Page>

      (a) Lessee agrees, and shall require any Permitted Sublessee or assignee
to agree, to pay, and indemnify, defend and hold harmless each Indemnitee from
any and all Tax, howsoever imposed, whether levied or imposed upon or asserted
against such Indemnitee, Lessee, the Aircraft, the Airframe or any Engine or
Part 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 by any territory or possession of the United States or by any
international authority, upon or with respect to (a) the Aircraft, the Airframe
or any Engine or Part or any part thereof or any contract relating to the
manufacture, construction, acquisition or delivery thereof, (b) the manufacture,
construction, ordering, purchase, ownership, improvement, location, storage,
transportation, delivery, non-delivery, acceptance, operation, leasing,
re-leasing, possession, control, use, maintenance, replacement, modification,
insuring, registration, reregistration, titling, licensing, financing,
refinancing, documentation, importation, exportation, transfer of title,
transfer of registration, imposition of any Lien, return, abandonment, sale or
other application or disposition thereof, (c) the rentals, receipts or earnings
arising from the Aircraft, the Airframe or any Engine or Part, (d) this Lease,
the Lease Supplement, and any other documents contemplated hereby and amendments
and supplements hereto and thereto which have been approved by Lessee or the
execution, delivery or performance of any thereof or the issuance, acquisition,
holding or subsequent transfer thereof, (e) any amount paid or payable pursuant
to this Lease or any document related hereto or the property or the income or
other proceeds with respect to the Aircraft, or upon the Rent payable by Lessee
hereunder, or (f) otherwise with respect to or in connection with the
transactions contemplated by this Lease. Lessee further agrees that any payment
or indemnity pursuant to this Section 12.3 in respect of any Tax shall be in an
amount which, after deduction of all Taxes required to be paid 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, or any
territory or possession of the United States or any international authority,
shall be equal to the excess, if any, of (i) the amount of such Tax over (ii)
the net reduction in Tax required to be paid by such recipient by reason of the
accrual or payment of such Tax. For purposes of the foregoing, it shall be
assumed that each Indemnitee is subject to tax at the highest marginal rate
imposed on or measured by the income of corporations in each applicable taxing
jurisdiction. With respect to any Tax in the nature of a withholding tax, Lessee
shall comply with the requirements set forth in Section 12.8 hereof. All of the
indemnities contained in this Section 12.3 shall continue in full force and
effect notwithstanding the expiration or other termination of the Term.

      12.4. EXCLUSIONS FROM GENERAL TAX INDEMNITY. The indemnity provided for in
Section 12.3 above shall not extend or apply to any of the following:

                  (a) any Income Tax imposed on an Indemnitee by (i) the United
            States federal government, (ii) any state or local government, (iii)
            any foreign government or any political subdivision or taxing
            authority thereof, (iv) any territory or possession of the United
            States, or (v) any international authority; provided, however, that
            such exclusion shall not apply to any Income Tax to the extent that
            (A) such Income Tax is imposed by any jurisdiction in which such
            Indemnitee would not be subject to Income Tax but for or as a result
            of (I) the

                                      41
<Page>

            operation, registration, location, presence, or use of the Aircraft,
            the Airframe, any Engine or any Part thereof, or (II) the place of
            organization or principal office or the activities of Lessee or any
            Permitted Sublessee in such jurisdiction, and (B) exceeds the amount
            of Income Tax for which the Indemnitee would otherwise have been
            liable in the absence of the circumstances referred to in (I) and
            (II).

                  (b) any tax imposed on or with respect to an Indemnitee
            resulting from any voluntary transfer by such Indemnitee of any
            interest in the Aircraft, the Airframe, any Engine or any Part, or
            any involuntary transfer of the Aircraft, the Airframe or any Engine
            or any Part in connection with any bankruptcy or similar proceeding
            for the relief of debtors in which such Indemnitee is the debtor or
            any foreclosure by a creditor of such Indemnitee with respect
            thereto, other than a transfer pursuant to the exercise of remedies
            while an Event of Default shall have occurred and be continuing;

                  (c) any tax imposed on or with respect to an Indemnitee
            resulting from such Indemnitee's gross negligence or willful
            misconduct.

                  (d) any Tax attributable to the Aircraft that is imposed with
            respect to any period after the expiration of the Term and the
            return of possession of the Aircraft to Lessor in accordance with
            the terms of Section 8; provided, however, that the exclusion set
            forth in this paragraph shall not apply to any Taxes or other
            impositions relating to events occurring or matters arising prior to
            or simultaneously with such expiration.

                  (e) any Tax imposed on or with respect to an assignee or
            successor of the interest of an Indemnitee to the extent that such
            Tax would not have been imposed on or with respect to the assignor
            Indemnitee (other than a Tax imposed on an assignee of the
            Indemnitee who became such following the exercise by Lessor of its
            remedies under Sectionn 15).

                  (f) any Tax that would not have been imposed but for a Lessor
            Lien.

                  (g) any event or occurrence for which Lessee is obligated
            under this Lease to make a payment of Stipulated Loss Value or an
            amount determined by reference to the Stipulated Loss Value;

                  (h) the failure of an Indemnitee to exercise its contest
            rights as and to the extent required hereunder; or

                  (i) the failure of any Indemnitee to file proper and timely
            reports or returns or to pay any taxes when due or to claim an
            applicable exemption.

      12.5. CONTESTS. If a written claim is made by any taxing authority against
an Indemnitee for any Tax with respect to which Lessee is required to indemnify
hereunder, such Indemnitee shall promptly give Lessee written notice of such
claim. An Indemnitee's failure to

                                      42
<Page>

provide such notice to Lessee (for reasons other than Lessee's failure to
fulfill its obligations to Indemnitee under this Lease) shall not diminish
Lessee's obligations or such Indemnitee's rights hereunder except to the extent
that such failure precludes Lessee's and such Indemnitee's ability to contest
such Tax. If Lessee promptly (and, in any event, within 15 days of receipt of
notice from the Indemnitee) requests the Indemnitee to do so, the Indemnitee
shall, at Lessee's expense, contest (or, at the Indemnitee's option, require
Lessee to contest in Lessee's name, if permitted by law) the validity,
applicability or amount of any such Tax. The Indemnitee shall determine in its
sole discretion the forum in which the contest of such Tax shall be pursued and
whether such contest shall be by (i) resisting payment thereof, if lawful and
practicable, (ii) not paying the same except under protest, if protest is
necessary or advisable and proper, or (iii) if the payment is made, using
reasonable efforts to obtain a refund thereof in appropriate administrative and
judicial proceedings. If the Indemnitee determines that such contest shall be by
the manner described in either of clauses (ii) or (iii) above, Lessee shall
advance sufficient funds on an interest-free basis to the Indemnitee to make the
payment required. If an Indemnitee contests the validity, applicability or
amount of any Tax hereunder, Lessee shall have the right to participate in such
contest at its own expense, including the right to attend governmental or
judicial conferences concerning such claim for Tax and the right to review and
advise the Indemnitee as to all material written submissions to any governmental
or other authority relating to the Tax for which indemnification is sought.
Notwithstanding the foregoing, the Indemnitee shall only be required to contest
(and Lessee shall only be permitted to contest) any Tax if (A) independent tax
counsel selected by the Indemnitee is of the opinion that there is a reasonable
basis for contesting the matter in question; (B) Lessee has acknowledged in
writing its liability to indemnify the Indemnitee with respect to the Tax in
question; (C) Lessee shall pay (and shall acknowledge in writing Lessee's
liability to pay) the Indemnitee on demand for all reasonable costs and expenses
incurred by such Indemnitee incurs in connection with contesting such claim
(including, without limitation, all costs, expenses, losses, reasonable legal
and accounting fees (including fees associated with the Indemnitee's
consultation with independent tax counsel as described herein), disbursements,
penalties, interest and additions to tax); (D) the issue shall not be the same
as an issue previously contested hereunder and decided adversely unless
independent tax counsel selected by the Indemnitee is of the opinion that the
applicable law has changed, and (E) the amount of Tax at issue exceeds $25,000.
The Indemnitee shall not be required to appeal any judicial decision unless it
receives an opinion of independent counsel selected by such Indemnitee to the
effect that it is more likely than not that such appeal would be successful.
Under no circumstances shall the Indemnitee be required to appeal a decision to
or request a hearing by the United States Supreme Court. Nothing in this Section
12.5 shall require any Indemnitee to contest, or permit Lessee to contest, a
claim with respect to the imposition of any Tax if such Indemnitee shall waive
its right to indemnification under Section 12.3 with respect to such claim.

      12.6. SETTLEMENTS. If, in the course of exercising its contest rights on
Lessee's behalf, an Indemnitee learns that a taxing authority asserting a claim
for which indemnity is sought hereunder is willing to agree to a settlement of a
claim, such Indemnitee shall notify Lessee of such settlement proposal
("Settlement Proposal"). If the Settlement Proposal is acceptable to Lessee,
Lessee shall so notify such Indemnitee, provided that an Indemnitee shall not be
obligated to agree to the Settlement Proposal if such Indemnitee releases Lessee
from any

                                      43
<Page>

additional obligations pursuant to Section 12.3 with respect to such tax claim
and agrees that the amount of any indemnity payment under this Section 12.3 in
respect of such tax claim which Lessee shall be required to pay to such
Indemnitee shall not exceed the amount of such indemnity payment that would have
been required if such Indemnitee had agreed to the Settlement Proposal. If
Lessee declines the Settlement Proposal, Lessee shall notify Indemnitee in
writing of the amount for which Lessee would be reasonably willing to settle
such claim ("Lessee's Settlement Proposal"), and Indemnitee shall notify the
taxing authority of Lessee's Settlement Proposal. If the taxing authority does
not accept Lessee's Settlement Proposal, Indemnitee shall have the option of (i)
rejecting the Settlement Proposal, (ii) requiring Lessee to assume full
responsibility for the tax claim, or (iii) accepting the Settlement Proposal, in
the case of the Lessee's acceptance of the Settlement Proposal, the amount of
any indemnity payment determined under this Section 12.6 in respect of such tax
claim that Lessee shall be required to pay shall not exceed the amount for which
Lessee would have been willing to settle such tax claim.

      12.7. REPORTS. Lessee shall promptly notify Indemnitee of all reports or
returns required to be made with respect to any Tax with respect to which Lessee
is required to indemnify hereunder (provided, however, that this shall not be
deemed to require Lessee to file Indemnitee's Income Tax returns), and will
provide Indemnitee with all information necessary for the making and timely
filing of such reports or returns by Indemnitee. If Indemnitee requests that any
such reports or returns be prepared and filed by Lessee, Lessee shall prepare
and file the same, if permitted by applicable law to do so, and if not so
permitted, Lessee shall prepare such reports or returns for signature by Lessor,
and shall forward the same, together with immediately available funds for
payment of any Tax due, at least five Business Days in advance of the date such
payment is to be made, unless payment of such Tax is being resisted in
accordance with the provisions of Section 12.5.

      12.8. PAYMENT. Lessee shall pay any Tax directly to the appropriate taxing
authority if legally permissible, unless such Tax is being contested or resisted
in accordance with the provisions of Section 12.5, and upon demand of an
Indemnitee shall pay such Tax and any other amounts due hereunder to such
Indemnitee within five Business Days of such demand, but in no event shall any
such payments be made less than three Business Days prior to the date the Tax to
which any such payment hereunder relates is due (unless Lessee has not received
such demand at least 15 Business Days prior to such date, in which case payment
shall be made within five Business Days after receipt of such demand), in
immediately available funds, unless such Tax is being resisted in accordance
with the provisions of Section 12.5. Any such demand for payment from an
Indemnitee shall specify in reasonable detail the payment and the facts upon
which the right to payment is based. Each Indemnitee shall promptly forward to
Lessee any correspondence, notice, bill or advice received by it concerning any
Tax indemnified against hereunder unless such correspondence, notice, bill or
advice also addresses issues unrelated to the transactions contemplated under
this Lease (in which case, the unrelated issues shall be redacted). As soon as
practicable after each payment by Lessee of any Tax indemnified against
hereunder, Lessee shall furnish the appropriate Indemnitee the original or a
certified copy of a receipt for Lessee's payment of such Tax or such other
evidence of payment of such Tax as is reasonably acceptable to such Indemnitee.
Lessee shall also furnish promptly upon request such

                                      44
<Page>

data as any Indemnitee may reasonably require to enable such Indemnitee to
comply with the requirements of any taxing jurisdiction.

      12.9. REFUNDS. Upon receipt by an Indemnitee of a refund of any amounts
paid by it in respect of any contested Tax which amounts were advanced to the
Indemnitee by Lessee or otherwise paid by Lessee, such Indemnitee shall pay to
Lessee the amount of such refund, together with any interest received by such
Indemnitee on such refund that is fairly attributable to the amount and the
period of such payment or advance by Lessee (net of any taxes payable with
respect to the receipt or accrual of such interest by such Indemnitee); and,
upon disallowance of any portion of such requested refund, Lessee shall forgive
the related amount advanced to such Indemnitee with respect to the contested
Tax, and such forgiveness shall be treated for purposes of this Agreement as a
payment pursuant to Section 12.2.

      12.10. WITHHOLDING. If Lessee is required at any time to deduct or
withhold any Tax imposed by any taxing authority on any payment hereunder,
Lessee shall immediately pay to Lessor or other affected Indemnitee such
additional amounts (as Supplemental Rent) at such times as shall result in the
net amount actually received by the Lessor or such other Indemnitee being, after
taking into account (i) the amount of such deduction or withholding and (ii) the
amount of any Tax required to be paid by Lessor or such other Indemnitee by
reason of any payments made by Lessee pursuant to this Section 12.10, equal to
the full amount which would have been received by Lessor or such other
Indemnitee had such deduction or withholding not been made and such additional
Tax imposed and shall ensure that the foregoing shall be free of expense to
Lessor or such other Indemnitee for collection or other charges and shall pay to
the relevant taxing authority within the period for payment permitted by
applicable law the full amount of the deduction or withholding.

      12.11. INTEREST. Lessee shall pay to each Indemnitee upon demand, to the
extent permitted by law, interest on the amount of any indemnity under this
Section 12 not paid when due at the Past Due Rate.

SECTION 13. ASSIGNMENTS AND SUBLEASING.

      13.1. BY LESSEE. Except as specifically permitted under this Lease, Lessee
shall not, without the prior written consent of Lessor, assign any of its rights
in, to or under this Lease or the Lease Supplement, or Permitted Sublease or
otherwise transfer its interest in the Aircraft. Any such assignment, Permitted
Sublease or transfer shall in no way relieve Lessee from any obligation under
this Lease, which shall be and remain primary obligations of Lessee. The rights
of any Permitted Sublessee shall be subject and subordinate to all the terms of
this Lease (and the Permitted Sublease shall expressly so state). Each Permitted
Sublease in excess of one year by its term shall be assigned to or for the
benefit of Lessor. Notwithstanding the foregoing, Lessee shall not sell all or
substantially all of its assets or merge or consolidate with any other Person,
without the consent of the Lessor; provided, however, that notwithstanding the
foregoing, Lessee shall have the right, without the consent of Lessor, to merge
with any Person, provided that (A) immediately after any such transaction, no
Event of Default has occurred and is continuing, and (B) such Person which is to
be the transferee or surviving or acquiring corporation in such transaction (i)
shall be duly organized and validly existing under the laws of the United States
of

                                      45
<Page>

America or a state thereof, or the District of Columbia, and a "citizen of the
United States" as defined in 49 U.S.C. ss. 40102(a)(15) of the Transportation
Act, (ii) shall be a U.S. Air Carrier, (iii) shall (unless Lessee is the
survivor), by agreement in writing, which shall be in form and substance
reasonably satisfactory to Lessor, expressly assume the due and punctual payment
of the Rent and other sums due and to become the due under this Lease and the
due and punctual performance and observance of all the covenants and provisions
of this Lease, and (C) in all cases, the assignee or transferee of Lessee's
assets or the survivor of the merger or consolidation has a tangible net worth
at least equal to Lessee's tangible net worth as of the date hereof.

      13.2. PERMITTED SUBLEASES. Provided that no Event of Default has occurred
and is continuing, Lessee may, during the Basic Term, without the prior consent
of Lessor, enter into a Permitted Sublease with respect to any Engine or the
Airframe and Engines or engines then installed on the Airframe to any Permitted
Sublessee if:

      (a) Lessee provides written notice to Lessor promptly after entering into
any such Permitted Sublease.

      (b) The Permitted Sublessee under such Permitted Sublease is not subject
to a proceeding or final order under applicable bankruptcy, insolvency or
reorganization laws on the date such Permitted Sublease is entered into or has
not declared a general moratorium on payment to U.S. creditors.

      (c) In the event that the Permitted Sublessee under such Permitted
Sublease is a foreign air carrier or Person based in a country other than the
United States, there has been no material adverse change in Lessee's tangible
net worth as of the date hereof and there are no external or internal wars or
conflicts involving such country at the time such Permitted Sublease is entered
into and the United States maintains normal diplomatic relations with the
country in which such proposed Permitted Sublessee is principally based;

      (d) In the event that the Permitted Sublessee under such Permitted
Sublease is a foreign air carrier or Person based in a country other than the
United States, prior to the effectiveness of such Permitted Sublease Lessor
shall have received an opinion, in form and substance reasonably acceptable to
Lessor of counsel to Lessee reasonably acceptable to Lessor to the effect that
(i) the terms of the proposed Permitted Sublease will be legal, valid, binding
and (subject to customary exceptions) enforceable against the proposed Permitted
Sublessee in the country in which the proposed Permitted Sublessee is
principally based; (ii) there exist no possessory rights in favor of the
Permitted Sublessee under such Permitted Sublease under the laws of such
Permitted Sublessee's country of domicile that would, upon bankruptcy or
insolvency of or other default by the Lessee and assuming that at such time such
Permitted Sublessee is not insolvent or bankrupt, prevent or unreasonably delay
the return or repossession of the Aircraft in accordance with and when permitted
by the terms of Section 14 upon the exercise by Lessor of its remedies under
Section 15; (iii) the laws of such Permitted Sublessee's country of domicile
require fair compensation by the government of such jurisdiction for the loss of
use of or title to such Engine or Airframe in the event of the requisition by
such government of such use or title (it being understood that in the event such
opinion cannot be given in a form reasonably satisfactory to Lessor, such
opinion shall be waived if insurance reasonably

                                      46
<Page>

satisfactory to Lessor is provided to cover such requisition), (iv) the laws of
such Permitted Sublessee's country of domicile would give recognition to
Lessor's title to such Engine or the Airframe and to the registration of such
Engine or the Airframe in the name of Lessor (or Lessee as the proposed
sublessor or the proposed Permitted Sublessee, as appropriate), (v) all filings,
if any, required to be made in such jurisdiction in connection with the
execution of such Permitted Sublease in order to protect the interest of Lessor
in such Engine or the Airframe have been made, and (vi) the agreement of such
Permitted Permitted Sublessee that its rights under the Permitted Sublease are
subject to subordinate and all the terms of this Lease is enforceable against
such Permitted Permitted Sublessee under the applicable law of such country;

      (e) If the Permitted Permitted Sublessee is not a U.S. Air Carrier or is a
tax-exempt entity within the meaning of Section 168(h) of the Code, no Permitted
Sublease shall be allowed prior to the end of the recovery period with respect
to the Aircraft, unless Lessee prepays on a lump-sum basis any resulting
liability due under the Tax Indemnity Agreement based upon the assumption that
such Permitted Sublease will continue for the full term of such Permitted
Sublease; and

      (f) Lessee shall include in such Permitted Sublease appropriate provisions
which (i) make such Permitted Sublease expressly subject and subordinate to all
of the terms of this Lease, including the rights of Lessor to avoid such
Permitted Sublease in the exercise of its rights to repossession of the Airframe
and Engines hereunder and thereunder; (ii) expressly prohibit any further
subleasing of the Airframe and Engines; (iii) require that the Airframe and
Engines be maintained in accordance with a Maintenance Program; (iv) limit the
term of such Permitted Sublease (including renewal rights) to a period not
beyond the end of the Term, unless Lessee has then irrevocably committed to
exercise a purchase or extension option in accordance with the terms hereof; (v)
require that the Airframe and Engines be used in accordance with the limitations
applicable to Lessee's possession and use provided in this Lease; (vi) shall
include provisions for the maintenance, operation, possession and inspection of
the Aircraft that are the same in all material respects as the applicable
provisions of this Lease; and (vii) require insurance coverage to be maintained
to at least the same extent as set forth in this Lease.

      13.3. ASSIGNMENT BY LESSOR.

      (a) Lessor may voluntarily, at any time, upon ten Business Days prior
written notice to Lessee, assign, sell or transfer, all, but not less than all
of its right, title and interest in, to and under the Aircraft, this Lease and
the Lease Supplement, to a single transferee either through assignment of its
beneficial interest or through the sale or other transfer of all or
substantially all of its assets or business, in either case only if the
transferee (i) is a corporation or financial institution which is a "citizen of
the United States" as defined in the Transportation Code, (ii) has a net worth
of not less than $50,000,000 (or provides a guarantee of all of its obligations
by an entity meeting such net worth requirement), (iii) assumes the obligations
of Lessor in the transaction, and (iv) is not, without the written consent of
Lessee, an airline or any other competitor of Lessee or an affiliate of any
thereof. The provision of this Section 14(a) shall not apply to any transfer or
assignment pursuant to an exercise by Lessor of its remedies under Section 15.

                                      47
<Page>

      (b) Lessor may encumber the Aircraft or assign its interest or any part
thereof under this Lease to a lender as security for the purpose of refinancing
its interest in the Aircraft.

      (c) Any assignment or encumbrance by Lessor pursuant to this Section 13.3
shall be subject to Lessee's rights hereunder. Lessee shall be under no
obligation to any assignee except upon written notice of such assignment from
Lessor. Upon written notice to Lessee of such assignment, Lessee agrees to pay
Rent to the assignee in accordance with the instructions specified in such
notice, and to give all notices which are required or permitted to be given by
Lessee to Lessor hereunder to the Person(s) specified to receive the same in
such written notice of assignment, and to otherwise comply with all notices,
directions and demands which may be given by such assignee in accordance with
the provisions of this Lease. Lessor shall pay all costs and expenses incurred
in connection with any such transfer, assignment or encumbrance, including those
of Lessee, except if such transfer, assignment or encumbrance is pursuant to the
exercise by Lessor of its rights and remedies under Section 15 hereof.

      SECTION 14.  EVENTS OF DEFAULT.

      (a) Each of the following events shall separately 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
administrative or governmental body), and each such Event of Default shall
continue for so long as, but only for so long as, it shall not have been
remedied:

            (i) Lessee shall fail to make a payment of Basic Rent or Stipulated
      Loss Value within five Business Days after the same shall have become due;

            (ii) Lessee shall fail to make any other payment required hereunder
      or under any other agreement executed by Lessee in respect hereof within

      other document or certificate furnished by Lessee in connection herewith
      or therewith or pursuant hereto or thereto (other than the Tax Indemnity
      Agreement) and such failure shall continue unremedied for a period of more
      than 30 days after Lessee's receipt of written notice thereof by Lessor,
      unless such failure is not reasonably capable of being corrected within 30
      days, provided, however, that Lessee shall not be in default for so long
      as Lessee diligently commences and continues to diligently to correct such
      failure; provided, further, that Lessee shall in all events be in default
      or if Lessee does not remedy such failure within 120 days after receipt of
      such notice;

SECTION 15. REMEDIES.

      15.1. LESSOR'S REMEDIES. Upon the occurrence of any Event of Default and
at any time thereafter so long as the same shall be continuing, Lessor may, at
its option, declare this Lease to be in default by written notice to Lessee;
provided, however, that this Lease shall be deemed to be declared in default
without the necessity of such written declaration upon the occurrence of

                                      49
<Page>

any Event of Default described in Section 14(v) or Section 14(vi); and at any
time thereafter, so long as any such outstanding Event of Default shall not have
been cured or 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 requirements of, applicable law then in effect:

            (a) Lessor may, upon the written demand of Lessor and at Lessee's
      expense, cause Lessee to return promptly, and Lessee shall return
      promptly, all or such part of the Airframe or any Engine as Lessor may so
      demand, to Lessor or its order in the manner and condition required by,
      and otherwise in accordance with all the provisions of, Section 8 as if
      the Airframe or Engine were being returned at the end of the Term, or
      Lessor (or Lessor's designee) may, at its option, enter upon the premises
      where all or any part of the Airframe or any Engine is located and take
      immediate possession of and remove the same (together with any engine that
      is installed on the Airframe which is not an Engine, subject to the rights
      of any owner, lessor, lienholder or secured party of such engine) by
      summary proceedings or otherwise (and/or, at Lessor's option, store the
      same at Lessee's premises, at Lessee's cost and expense, until disposal
      thereof by Lessor);

            (b) Lessor may sell all or any part of the Aircraft, the Airframe or
      any Engine at public or private sale and with or without advertisement or
      notice to Lessee or any Permitted Sublessee, as Lessor in its sole
      discretion may determine, or otherwise dispose of, hold, use, operate,
      lease to others or keep idle all or any part of the Aircraft, the Airframe
      or any Engine as Lessor, in its sole discretion, may determine, all free
      and clear of any rights of Lessee or any Permitted Sublessee and without
      any duty to account to Lessee or any Permitted Sublessee with respect to
      such action or inaction, except as hereinafter set forth in this Section
      15; and in the event of a sale in accordance with the foregoing, Lessor
      shall have the right to bid for and purchase such property;

            (c) In the event Lessor, pursuant to Section 15.1(b), shall have
      sold the Aircraft, Lessor may, if it shall so elect, demand that Lessee
      pay Lessor, and Lessee shall pay to Lessor, on the date of such sale, as
      liquidated damages for loss of a bargain and not as a penalty, any unpaid
      Basic Rent and Supplemental Rent with respect to the Aircraft due on or
      prior to such date plus the amount of any deficiency between the net
      proceeds of such sale (after deduction of all reasonable costs of sale)
      and the Stipulated Loss Value of the Aircraft, computed as of the Rent
      Payment Date immediately following the date of such sale, together with
      interest, if any, on the amount of such deficiency, at the Past Due Rate,
      from the date of such demand to the date of actual payment of such amount;

            (d) In lieu of exercising its rights under Section 15.1(a), (b) or
      (c) above, Lessor may, by notice to Lessee specifying a payment date not
      earlier than ten days or more than 30 days from the date of such notice,
      require Lessee to pay to Lessor, and Lessee hereby agrees that it will pay
      to Lessor, on the payment date specified in such notice, as liquidated
      damages for loss of a bargain, and not as a penalty, and in lieu of any
      further payments of Basic Rent hereunder, an amount equal to the sum of
      (i) all unpaid Basic Rent payable or that would have been payable on or
      before the date of payment

                                      50
<Page>

      specified in such notice and any Supplemental Rent then owing, plus (ii)
      an amount equal to the Stipulated Loss Value for the Aircraft computed as
      of the Rent Payment Date immediately following the date of payment
      specified in such notice, together with interest, if any, at the Past Due
      Rate on the amount of such Basic Rent and Stipulated Loss Value from the
      payment date specified in such notice until the date of actual payment;
      and upon such payment of liquidated damages and all other Rent then due
      and payable by Lessee hereunder, Lessor shall transfer (without any
      representation, recourse or warranty whatsoever other than as to the
      absence of Lessor Liens) the Aircraft to Lessee or as Lessee may direct,
      and Lessor shall execute and deliver such documents evidencing such
      transfer and take such further action as Lessee shall reasonably request;

            (e) Lessor may rescind this Lease Agreement and/or may exercise any
      other right or remedy which may be available to it under applicable law or
      proceed by appropriate court action to enforce the terms hereof or to
      recover damages for breach hereof;

      15.2. Except as otherwise expressly provided above, no remedy referred to
in this Section 15 is intended to be exclusive, but each shall be cumulative and
in addition to any other remedy referred to above or otherwise available to
Lessor at law or in equity, and the exercise or beginning of exercise by Lessor
of any one or more of such remedies shall not preclude the simultaneous or later
exercise by Lessor of any or all 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 any
future or subsequent Event of Default;

SECTION 16. FURTHER ASSURANCES; INFORMATION.

      (a) On the Delivery Date, Lessee shall cause this Lease and the Lease
Supplement to be duly filed at the FAA. In addition, Lessee will promptly and
duly execute and deliver to Lessor and any assignee of Lessor permitted under
Section 13.3 hereof such other documents and assurances, and will take such
further actions as Lessor or any such assignee may from time to time reasonably
request in order to carry out more effectively the intent and purposes of this
Lease and to establish and protect the rights and remedies created or intended
to be created hereunder in favor of Lessor and any such assignee, including,
without limitation, if requested by Lessor, at the expense of Lessee, the
execution and delivery of supplements or amendments hereto, subjecting to this
Lease any airframe or engine substituted for an Airframe or any Engine, and the
recording or filing of counterparts thereof in accordance with the laws of such
jurisdictions as Lessor may from time to time reasonably deem advisable.

      (b) Lessee convenants to furnish to Lessor such information concering the
business, assets and financial condition of Lessee as Lessor may request and,
without request, furnish to Lessor:

            such quarter and the fiscal year to date;

            occurred and is continuing hereunder; and

            notice of the occurrence of an Event of Default.

designate in writing to Lessor.

SECTION 18. NET LEASE, NO SET-OFF, COUNTERCLAIM, ETC. This is a triple-net
lease, and Lessee's obligations to pay all Rent payable hereunder and to pay all
costs and expenses of every kind in connection with the use, operation,
maintenance and repair of the Airframe and each Engine by Lessee shall be
absolute and unconditional and shall not be affected by or subject to any
circumstance, including, without limitation, (i) any setoff, counterclaim,
recoupment, abatement, defense or other right which Lessee may have against
Lessor or anyone else for any reason whatsoever (whether in connection with the
transactions contemplated hereby or any other transactions), (ii) any defect in
the title, registration, airworthiness, condition, design, operation, or fitness
for use of, or any damage to or loss or destruction of, the Aircraft, or any
interruption, interference or cessation in or prohibition of the use or
possession thereof by Lessee (or any Permitted Sublessee) for any reason
whatsoever, including, without limitation, any such interruption, interference,
cessation or prohibition resulting from the act of any government authority,
(iii) any insolvency, bankruptcy, reorganization or similar case or proceedings
by or against Lessee (or any Permitted Sublessee), Lessor or any other Person,
(iv) the invalidity or unenforceability or lack of due authorization of this
Lease or any instrument or document executed in connection herewith or
therewith, or (v) any other circumstance, happening, or event whatsoever,
whether or not unforeseen or similar to any of the foregoing. If for any reason
whatsoever this Lease shall be terminated in whole or in part by operation of
law or otherwise except as specifically provided herein, Lessee nonetheless
agrees without limitation of the other rights or remedies of Lessor hereunder,
to pay to Lessor an amount equal to each Rent payment at the time such payment
would have become due and payable in accordance with the terms hereof had this
Lease not been terminated in whole or in part. 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, cancel, quit or surrender this Lease except in accordance with the
express terms hereof. Each payment of Rent by Lessee shall be final, and Lessee
shall not seek to recover, abate, suspend, defer or reduce all or any part of
such payment for any reason whatsoever, except for any payments not required
hereunder which were made in error. Nothing in this Section 18 shall be
construed to preclude Lessee from bringing any suit at law or in equity which it
would otherwise be entitled to bring for breach of any representation, warranty,
or covenant hereunder, or as a waiver of or consent to any act or failure to act
by any person except as otherwise expressly provided in this Lease.

SECTION 19. LESSOR'S RIGHT TO PERFORM FOR LESSEE. If Lessee fails to make any
payment of Supplemental Rent required to be made by it hereunder or fails to
perform or comply with any of its agreements contained herein, in either case,
after the expiration of any applicable notice and cure periods, whether or not
such failure shall constitute an Event of Default hereunder, Lessor may itself
make such payment or perform or comply with such agreement but shall not be
obligated hereunder to do so, and the amount of such payment and the amount of
the reasonable expenses of 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 Past Due Rate, shall be deemed
Supplemental Rent hereunder payable by Lessee to Lessor on

                                      53
<Page>

demand. No such payment or performance by Lessor shall be deemed to waive any
Default or Event of Default or relieve Lessee of its obligations hereunder.

SECTION 20. LESSOR ASSIGNMENT OF RIGHTS AND WARRANTIES. On the Delivery Date,
Lessor shall assign to Lessee for the duration of the Lease Term, the benefit of
all assignable manufacturer's warranties with respect to the Aircraft as well as
all manuals and related services and documentation available to Lessor, and
Lessor agrees to use its reasonable efforts, at Lessee's expense and upon its
written request, to assist Lessee in enforcing such rights as Lessor may have
with respect to the warranties for the benefit of Lessee; provided, however,
that upon notice from Lessor to Lessee after and during the continuance of an
Event of Default, such assignments which are otherwise made available to Lessee
shall immediately upon notice by Lessor be deemed canceled and shall be deemed
reassigned to Lessor, including all claims thereunder, whether or not perfected,
and all amounts payable shall be paid to and held by Lessor, until such time as
an Event of Default is no longer continuing. At the expiration of the Term of
this Lease (other than by reason of the exercise by Lessee of its purchase
option), the benefit of any assignment to Lessee shall automatically and without
further action by Lessor revert to Lessor or its designee. Lessee shall at its
own cost and expense do all such things and execute all such documents as may be
required for this purpose. Lessee shall maintain all necessary records and take
all necessary actions to qualify it for claims, and shall diligently and
promptly pursue any valid claims it may have against the manufacturers with
respect to the Aircraft and will provide notice of same to Lessor. Lessee shall
cooperate with Lessor, and shall furnish Lessor with such documents, records and
other information as Lessor shall reasonably request in order to assist Lessor
in pursuing any claim Lessor may have against any manufacturer with respect to
any warranty.

SECTION 21. MISCELLANEOUS. 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. No term or provision of this Lease may be changed, amended,
waived, discharged or terminated orally, but only by an instrument in writing
signed by Lessor and Lessee. This Lease shall constitute an agreement of lease,
and nothing contained herein shall be construed as conveying to Lessee any
right, title or interest in the Aircraft other than as a lessee. Neither Lessee
nor any Affiliate of Lessee shall file any tax returns in a manner inconsistent
with the foregoing or with Lessor's ownership of the Aircraft, and any Permitted
Sublease shall require a similar undertaking by the Permitted Sublessee
thereunder. The section and paragraph headings in this Lease and the table of
contents are for convenience of reference only and shall not modify, define,
expand or limit any of the terms or provisions hereof. This Lease may be
executed by the parties hereto in separate counterparts, each of which when so
executed and delivered shall be an original, but all such counterparts shall
together constitute but one and the same instrument.

SECTION 22. OPTIONS TO RENEW.

      22.1 CAPPED RENEWAL OPTIONS. Lessee shall have the right to extend the
term of this

                                      54
<Page>

Lease for a period of one year commencing at the end of the Basic Term by
irrevocable written notice to Lessor not less than 180 days prior to the end of
the Basic Term, provided that no Event of Default has occurred and is continuing
at the time of notice and commencement of the Renewal Term. In the event that
Lessee has elected to extend the Term in accordance with the preceding sentence,
Lessee shall have the right to extend the then-current Term for an additional
one-year period by irrevocable written notice given to Lessor not less than 180
days prior to the expiration of the then-current Term. The Rent payable during
each Renewal Term under this Section 22.1 shall be [*] (i) [*], or (ii) [*] of
the average Basic Rent paid during the Basic Term, and shall be paid on the
Rent Payment Dates.

      22.2 UNCAPPED RENEWAL OPTIONS. In the event that Lessee has exercised both
of its options to extend the Term pursuant to Section 22.1, Lessee shall have
two successive options to extend the Term for a period of one year each,
exercisable by written irrevocable notice to Lessor not less than 180 days prior
to the expiration of the then-current Term, provided no Event of Default has
occurred and is continuing at the time of the notice and the commencement of the
Renewal Term. The Basic Rent payable during each Renewal Term under this Section
22.2 shall be equal to [*], and shall be paid on the Rent Payment Dates.

      22.3 FAIR MARKET RENTAL VALUE. For the purposes of this Lease, the "Fair
Market Rental Value" of the Aircraft shall be the rent which would be payable in
an arm's length transaction between an informed and willing lessor under no
compulsion to lease and an informed and willing lessee under no compulsion to
lease, based upon the condition and location of the Aircraft (assuming the
Aircraft is in the condition in which it is required to be maintained and
further assuming half-life condition), which value shall be determined by mutual
written agreement or, in the absence of mutual written agreement, pursuant to
the appraisal procedure described in Section 23.3.

SECTION 23. PURCHASE OPTIONS.

      23.1 PURCHASE OPTIONS. Lessee shall have the right to purchase the
Aircraft (i) upon the termination of the Basic Term, for a purchase price equal
to the lesser of then Fair Market Sales Value of the Aircraft or the amount
specified on Schedule II; or (ii) at the end of any Renewal Term, for a purchase
price equal to the then Fair Market Sales Value of the Aircraft. Upon payment by
Lessee of the purchase price for the Aircraft and the Basic Rent or Renewal
Rent, if any, payable though the date of purchase, together with all
Supplemental Rent then due and payable hereunder (and provided that Lessee has
cured (or with such payments will cure) all Defaults, the Term shall end and the
obligation of Lessee to pay Rent hereunder (except for Supplemental Rent
obligations otherwise accrued but unpaid as of the date of such payment) shall
cease, and Lessor shall convey to Lessee all right, title and interest of Lessor
in and to the Aircraft on an "as-is, where is" basis, without recourse or
warranty except a warranty against Lessor's Liens.

      23.2 NOTICE. Lessee's right to purchase provided for Section 23.1 shall be
exercised by written notice to Lessor not less than 180 days before the
applicable date of purchase provided in Section 23.1(i) or Section 23.1(ii), as
the case may be. Such notice shall be irrevocable, except that Lessee may revoke
its exercise of an option to purchase the Aircraft within 15 days

                                      55

<Page>

following the determination of the Fair Market Sales Value. In the event that
Lessee exercises its right of revocation, the Term of this Lease shall be
extended to a date that is not earlier than 180 days following the notice of
revocation.

      23.3 FAIR MARKET SALES VALUE. For the purposes of this Lease, the "Fair
Market Sales Value" of the Aircraft shall be the sales value which would be
obtained in an arm's-length transaction between an informed and willing
purchaser under no compulsion to purchase and an informed and willing seller
under no compulsion to sell, based upon the condition and location of the
Aircraft (assuming the Aircraft is in the condition in which it is required to
be maintained and further assuming half-life condition), which value shall be
determined by mutual written agreement or, in the absence of mutual written
agreement, pursuant to an appraisal prepared and delivered by a nationally
recognized firm of independent aircraft appraisers nominated by Lessor and
approved by Lessee, and Lessor shall immediately notify Lessee in writing of
such nomination. The appraiser shall determine the Fair Market Sales Value
within seven Business Days, and its determination shall be final and binding
upon the parties. The cost of such appraisal or appointment shall be borne by
Lessee.

SECTION 24 VOLUNTARY TERMINATION FOR OBSOLESCENCE.

      24.1 RIGHT TO TERMINATE. So long as no Event of Default has occurred and
is continuing, Lessee shall have the right on at least [*] (which notice shall
be irrevocable, except as provided below), to terminate this Lease by written
notice from its chief financial officer to Lessor to the effect that the
Aircraft has become [*] to Lessee's equipment requirements. Such notice shall
specify a proposed date of termination, which shall be a Rent Payment Date at
any time on or after the [*] anniversary of the Commencement Date. During the
period following the giving of such notice of termination until the
Termination Date, Lessee, as agent for Lessor, shall use commercially
reasonable efforts to sell the Aircraft no later than the Termination Date
"as is", without any warranty by Lessor except as to Lessor's title, on
behalf of Lessor. If Lessee receives any bid, it shall, at least 10 Business
Days prior to the proposed day of sale, certify to Lessor in writing the
amount and terms of such bid, the proposed date of sale and the name and
address of the potential buyer (which may be Lessor or any Affilate of
Lessor, but shall not be Lessee or any Affiliate of Lessee). Lessor may also
solicit bids directly or through agents other than Lessee. Lessee may, by
notice to Lessor, withdraw its notice of termination at any time on or before
the date 10 days prior to the proposed Termination Date (unless such
withdrawal is due to the cancellation of the proposed purchase of the
Aircraft by the potential buyer, in which event, such notice may be given at
any time on or prior to the proposed Termination Date), and thereupon this
Lease shall continue in full force and effect. Withdrawal of notice of
termination shall not exhaust the Lessee's right to give a further notice of
termination as provided herein. On the Termination Date or such other date of
sale as shall be consented to in writing by Lessor and Lessee, which date
shall thereafter be deemed the Termination Date, Lessee shall, upon payment
in full of the amounts described in Section 24.2, deliver the Airframe and
Engines or engines installed thereon to the party which shall have prior to
such date submitted the highest bona fide cash bid to close such sale and
purchase of the same, and shall duly transfer to such party title to any
engines which are not Engines delivered with the Airframe. Lessor shall
simultaneously therewith sell and convey title

                                      56

to the Airframe and the Engines or engines conveyed to Lessor as provided in
Section 10 to such party, in "as-is, where-is" condition, without recourse or
warranty (except a warranty as to the absence of Lessor's Liens). Upon receipt
by Lessor of all amounts referred to in Section 24.2, Lessor will transfer to
Lessee, in "as-is, where-is" condition, without recourse or warranty (except a
warranty as to the absence of Lessor's Liens), all right, title and interest of
Lessor in and to any Engines constituting part of the Aircraft which were not
delivered to the purchaser with the Airframe. Lessee shall pay all reasonable
out-of-pocket expenses of Lessor in connection with any termination or proposed
termination of this Lease.

      24.2 PAYMENTS. The total selling price realized at any sale of the
Airframe and Engines or engines installed thereon in accordance with this
Section 24 shall be retained by Lessor. In addition, on the Termination Date
(including any tax indemnity payments that may have been paid by adjustment to
Basic Rent hereunder), Lessee shall pay to Lessor in immediately-available
funds, an amount equal to the sum of (i) the excess, if any, of the Termination
Value as of the Termination Date over the net proceeds of the sale of the
Aircraft, plus (ii) all unpaid Supplemental Rent due on or before the
Termination Date, plus (iii) the portion, if any, of Basic Rent payable through
Termination Date, together with all unpaid Basic Rent, if any, payable before
the Termination Date, plus (iv) the reasonable fees and expenses of Lessor in
connection therewith.

      24.3. TERMINATION OF LEASE. Upon delivery by Lessee of the Airframe and
Engines or engines installed thereon and payment by Lessee of all amounts
payable by Lessee under Section 24.2, the obligations of Lessee to pay Rent
shall cease and the Term shall end.

      24.4 EFFECT OF NO SALE. If, on the Termination Date, no sale of the
Aircraft has occurred, Lessee's termination notice given pursuant to Section
24.1 shall be deemed to be withdrawn as of such date, and this Lease shall
continue in full force and effect.

      24.5. NO DUTY ON PART OF LESSOR. Lessor shall be under no duty to solicit
bids, to inquire into the efforts of Lessee to obtain bids or otherwise to take
any action in connection with any such sale other than to cooperate with such
efforts as Lessee may reasonably request and to make the transfers described in
Section 24.1.

SECTION 25. COVENANT OF QUIET ENJOYMENT. Lessor covenants and agrees that, so
long as no Event of Default has occurred and is continuing hereunder, it will
not, nor will it permit another Person claiming by, under or through it to,
interfere with Lessee's right to quiet enjoyment and continuing possession, use
and operation of the Aircraft during the Term of this Lease, and this Lease
shall not be terminated except as expressly provided herein.

SECTION 26. BANKRUPTCY. It is the intention of the parties that Lessor shall be
entitled to the benefits of 11 U.S.C. ss. 1110 with respect to the right to
repossess the Airframe, Engines and Parts as provided herein. In any
circumstance where more than one construction of the terms and conditions of
this Lease is possible, a construction that would preserve such benefits shall
control over any construction which would not preserve such benefits or render
them doubtful. To the extent consistent with the provisions of 11 U.S.C. ss.
1110 or any analogous section of the Federal bankruptcy laws, as amended from
time to time, it is hereby expressly agreed and provided that,

                                      57
<Page>

notwithstanding any other provisions of the Federal bankruptcy laws, as amended
from time to time, to the contrary, any right of Lessor to take possession of
the Aircraft in compliance with the provisions of this Lease shall not be
effected by the provisions of 11 U.S.C. ss. 362 or 363, as amended from time to
time, or any analogous provisions of any superseding statute or any power of the
bankruptcy court to enjoin such taking of possession.

accordance with the laws of the State of New York, without regard to or
application of its conflict of laws rules.

the laying of venue of any suit, action or proceeding arising out of or relating
to this Lease brought in the Courts located in New York, New York, and hereby
further irrevocably waives any claim that any such suit, action or proceeding
brought in any such Court has been brought in an inconvenient forum. To the
extent that either Lessor or Lessee may be entitled at any time to claim for
itself or its assets any immunity (whether by reason of sovereignty or
otherwise) from suit, from the jurisdiction of any Court, from execution of
judgment or otherwise, Lessor or Lessee, as the case may be, hereby irrevocably
agrees not to claim and hereby irrevocably waives such immunity in respect of
this Lease and any proceeding under this Lease.

      27.3 WAIVER OF JURY TRIAL. Each party hereby unconditionally waives its
rights to a jury trial of any claim or cause of action based upon or arising out
of, directly or indirectly, this Lease, any of the documents relating hereto,
any dealings between Lessee and Lessor relating to the subject matter of this
transaction, and/or the relationship that is being established hereunder between
Lessee and Lessor. The scope of this waiver is intended to be all-encompassing
of any and all disputes that may be filed in any court (including, without
limitation, contract claims, tort claims, breach of duty claims, and all other
common law and statutory claims). This waiver shall apply to any subsequent
amendments, renewals, supplements or modifications to this Lease, any related
documents, or to any other documents or agreements relating to this transaction
or any related transaction. In the event of litigation, this Lease may be filed
as a written consent to a trial by the court.

      27.4 SERVICE OF PROCESS. Lessee hereby agree that service of all writs,
process and summonses in any such suit, action or proceeding brought in the
State of New York may be made upon Arthur Amron. Lessor agrees that service of

in the State of New York may be made upon Michael Babbit. Each party hereby
irrevocably appoints its process agent as its true and lawful attorney-in-fact
in its name, place and stead to accept such service of any and all such writs,
process and summonses, and agrees that the failure of its process agent to give
any notice of any such service of process to it shall not impair or affect the
validity of such service or of any judgment based thereon. Each of Lessee and
Lessor hereby further irrevocably consents to the service of process

                                      58

      1. THE LEASE. The Lease and all related documents to be executed by Lessee

authorized, executed and delivered by Lessee and constitute valid, legal and
binding agreements, enforceable against Lessee in accordance with their terms.
All of the terms and provisions (including defined terms) of the Lease are
hereby incorporated by reference in this Lease Supplement to the same extent as
if fully set forth herein. The parties confirm that the Delivery Date is the

            expressly relate to a particular date.

            (b) Lessee has satisfied or complied with all requirements set forth
            in the Lease to be satisfied or complied with on or prior to the
            date thereof.

<Page>

            of notice or lapse of time or both, would become an Event of Default
            or an Event of Loss.

            (d) The Lessee has obtained, and there are in full force and effect,
            such insurance policies with respect to the Aircraft as are required

      Attn:  Chief Financial Officer and General Counsel

                                          Re:   CHAUTAUQUA AIRLINES, INC.

      Gentlemen:

            Chautauqua Airlines, Inc., a New York corporation (the
"Corporation"), has asked us to render certain opinions to you regarding the
Corporation, and the following agreements to which the Corporation is a party:
(i) an Aircraft Lease Agreement, dated as of June 25, 1999, between ICX
Corporation, an Ohio corporation ("ICX"), and the Corporation (the "Lease");
(ii) a Lease Supplement, dated as of June 25, 1999, between ICX and the
Corporation; (iii) an Acceptance Certificate, dated as of June 25, 1999, between
ICX and the Corporation; and (iv) a Tax Indemnity Agreement, dated as of June
25, 1999, between ICX and the Corporation (collectively, the "Lease Documents").

            We have examined and relied upon originals, or copies certified or
otherwise identified to our satisfaction, of the following documents,
certificates and other statements of the Corporation and its officers and other
representatives as the basis for our opinion: (a) copies of the Lease Documents
in the form furnished to us by the Corporation; and (b) the opinion, dated as of
June 25, 1999, of Arthur Amron, General Counsel of the Corporation ("Counsel's
Opinion").

            In our examination of the Lease Documents, Counsel's Opinion and the
other documents, instruments, certificates and statements referred to above, we
have assumed, without any independent investigation, that (a) all statements,
representations, warranties and certifications set forth therein are true,
correct and complete; (b) the Lease Documents actually executed by the
Corporation are identical to the documents submitted to us by the Corporation;
(c) all documents submitted to us as originals are genuine and the signatures
thereon are authentic; (d) the agreements, documents, instruments and
certificates submitted to us as copies are genuine and conform to the originals;
and (e) the Lease Documents and all of the other agreements, documents,
instruments and certificates have been duly authorized, delivered and fully
performed by all persons other than the Corporation in all respects, and are the
legal, valid and binding obligations of all such persons, enforceable against
them in accordance with their respective terms. We have not represented the
Corporation generally as outside counsel, and,

                                      E-1
<Page>

accordingly, we have extremely limited familiarity with its business and
activities. Therefore, as to all factual matters, we have, without any
independent investigation, relied upon, and assumed the accuracy of, Counsel's
Opinion and all of the statements, representations and warranties made in the
Lease Documents and in each of the other agreements, documents, instruments,
certificates and statements referred to above.

            Based upon and subject to the foregoing, and subject to the
assumptions and qualifications set forth below, it is our opinion that:

            1. No authorization, approval, consent, license or order of, or
registration with, or giving notice to, any Federal governmental or other
regulatory body or authority having jurisdiction over the Corporation is
required or necessary for the valid authorization, execution, delivery and
performance by the Corporation of the Lease Documents.

            2. Each of the Lease Documents is a valid and a binding obligation
of the Corporation, enforceable against the Corporation in accordance with its
terms.

            3. The Corporation is a "citizen of the United States" as defined in
49 U.S. Code ss.40102(a)(15).

            4. The Corporation is an "air carrier" as defined in 49 U.S. Code
ss.40102(a)(2).

            5. Except for (i) registrations and filings with the FAA, with
respect to which we express no opinion; (ii) the filing of appropriate Uniform
Commercial Code financing statements in the appropriate offices in Indiana,
Ohio, New York and Connecticut, and any jurisdiction in which records relating
to the aircraft to which the Lease pertains (the "Aircraft") is located; (iii)
the filing of continuation statements at appropriate intervals with respect to
any Uniform Commercial Code financing statements; (iv) the filing of new
appropriate financing statements under the circumstances described in
ss.9-402(7) of the Uniform Commercial Code; and (v) the filing of new
appropriate financing statements in the appropriate offices in the appropriate
jurisdictions if the Corporation changes its location as determined under
ss.9-103(3)(d) of the Uniform Commercial Code, no further filing or recording of
any document with any court or governmental agency or body is necessary under
the laws of the States of Indiana, Ohio, New York or Connecticut in order to
give notice to third parties of ICX's right, title and interest in the Aircraft
as against the Corporation.

            The opinions expressed herein are qualified in their entirety as
follows: (a) no opinion is expressed with respect to laws other than the laws of

      Attn:  Chief Financial Officer and General Counsel

                                                      Re:   Chautauqua Airlines,
Inc.

      Gentlemen:

      I have acted as counsel for Chautauqua Airlines, Inc., a New York
corporation (the "Corporation"), in connection with the execution and delivery
of Aircraft Lease Agreement (N260SK) (the "Lease") between the Corporation and
ICX Corporation ("Lessor"), dated as of June 25, 1999, relating to the Embraer
ERJ-145LR aircraft bearing manufacturer's serial number EMB 145128; Lease
Supplement No. 1, dated as of June 25, 1999, between Lessor and Lessee; an
Acceptance Certificate, dated as of June 25, 1999, between Lessor and the
Corporation; and a Tax Indemnity Agreement, dated as of June 25, 1999, between
Lessor and Lessee (the Lease, the Lease Supplement, the Acceptance Certificate
and the Tax Indemnity Agreement are hereinafter collectively referred to as the
"Lessee Documents"). This opinion is being delivered to you pursuant to Section
5.1(g) of the Lease. Unless otherwise defined herein, capitalized terms used
herein have the meanings assigned to them in the Lease.

      In rendering this opinion, I have examined originals or copies, certified
or otherwise identified to my satisfaction, of the Lessee Documents, and have
investigated such questions of law, and have examined such other corporate
records of the Corporation and other documents, and have obtained and relied
(without independent investigation) upon such certificates and

<Page>

assurances from public officials, as I have deemed necessary as a basis for the
purpose of rendering this opinion.

      For the purpose of rendering this opinion, I have assumed, without any
independent investigation:

      A.    the genuineness of all signatures other than those of the
            Corporation, the capacity of all natural persons, the authenticity
            of all documents and instruments submitted to me as originals, and
            the conformity to authentic original documents and instruments of
            all documents and instruments submitted to me as certified,
            conformed photostatic or facsimile copies; and

      B.    that the documents reviewed by me constitute legal, valid and
            binding obligations of each party thereto, other than the
            Corporation, enforceable against each such party in accordance with
            their respective terms.

      Based upon and subject to the foregoing, and subject to the qualifications
set forth below, I am of the opinion that:

      1. The Corporation is duly incorporated, validly existing, and in good
standing under the laws of the State of New York, and has the corporate power
and authority to carry on its business as presently conducted and to perform its
obligations under the Lessee Documents.

      2. Each of the Lessee Documents has each been duly authorized, executed
and delivered by the Corporation.

      3. The execution and delivery of the Lessee Documents, the consummation by
the Corporation of the transactions contemplated thereby and compliance by the
Corporation with the terms and provisions thereof do not contravene, and will
not result in any breach of or constitute any default under, or result in the
creation of any lien, charge or encumbrance upon any property of the
Corporation, under any indenture, mortgage, chattel mortgage, deed of trust,
conditional sales contract, bank loan, credit agreement, corporate charter,
by-law or other agreement or instrument to which the Corporation is a party or
by which the Corporation or its properties or assets may be bound.

            4. The Corporation provides interstate transportation of passengers
or property by aircraft as a common carrier for compensation. The Corporation is
the holder of an air carrier operating certificate issued by the Federal
Aviation Administration under Part 135 of the Federal Aviation Regulations and
49 U.S. Code ss.44705 for aircraft capable of carrying ten or more individuals
or 6,000 pounds or more of cargo. The Corporation is an air carrier that
conducts air taxi operations under an exemption issued by the Department of
Transportation under authority of Part 298 of the Federal Aviation Regulations.
The Corporation holds all licenses, certificates and permits from applicable
governmental authorities necessary for the conduct of its business as an air
carrier and the performance of its obligations under the Lease.

<Page>

            5. There are no suits or proceedings, pending or threatened, against
the Corporation before any executive, legislative, judicial, administrative or
regulatory body which might, if adversely determined, have a material adverse
effect on the financial condition or business of the Corporation or its ability
to perform its obligations under the Lessee Documents.

            6. Neither the Corporation nor any of its properties or assets has
the right of immunity from suit or execution on the grounds of sovereignty.

            7. The Corporation is organized under the laws of the State of New
York. The president and at least two-thirds of the board of directors and other
managing officers of the Corporation are individuals who are citizens of the
United States. At least 75% of the voting interest in the Corporation is owned
or controlled, directly or indirectly, by individuals who are citizens of the
United States.

            The opinions expressed herein are qualified in their entirety as
follows: (a) no opinion is expressed with respect to laws other than the federal
laws of the United States and the State of New York; and (b) to the extent that
any one or more of the foregoing opinions relates to the enforceability of any
agreement or instrument: (1) the opinions are subject to the effect of
applicable laws or judicial decisions regarding bankruptcy, reorganization,
insolvency, fraudulent transfers, moratorium and other laws affecting creditors'
rights and debtors' relief generally; (2) the enforceability of the provisions
of any such agreement or instrument is subject to the application of principles
of equity, whether in a proceeding at law or in equity, including the exercise
of discretionary powers of any tribunal before which equitable remedies may be
sought (including, without limitation, specific performance and injunctive
relief); and (3) the enforceability of the provisions of any such agreement or
instrument in accordance with its respective terms may be limited by laws
affecting the remedies which it provides, including, but not limited to, laws
and judicial decisions limiting such enforceability.

      This opinion is rendered solely to you for your use in connection with the
transactions contemplated by the Lessee Documents, and may not be relied upon by
you for any other purpose, and may not be furnished to or relied upon by any
other person (other than Pearl Professional Corporation, which may rely upon
this opinion for purposes of rendering a separate opinion to you pursuant to
Section 5.1(g) of the Lease) for any purpose, or otherwise used, circulated or
quoted, without my prior written consent. This opinion is rendered as of the
date hereof, and I disclaim any undertaking to advise of any changes which may
hereafter be brought to my attention.

      Very truly yours,

      Arthur H. Amron
      General Counsel

              III. FORM OF OPINION LETTER TO BE GIVEN BY DAUGHERTY,
      FOWLER, PEREGRIN & HAUGHT, LESSEE'S OUTSIDE INDEPENDENT FAA COUNSEL

ICX Corporation
Three Summit Park Drive
Suite 200
Cleveland, Ohio  44131

Dear ______________:

      This opinion is furnished to you pursuant to Section 5.1 of the Aircraft
Lease Agreement dated as of June ___, 1999 (the "Lease") between ICX Corporation
("Lessor") and Chautauqua Airlines, ("Lessee") with respect to that portion of
the Federal Aviation Act of 1958, as amended (the "Act"), relative to the
recordation of instruments and the registration of aircraft under the Act.

      Capitalized terms not otherwise defined herein shall have the meanings
given them in the Lease.

                  We have examined and filed on this date with the Federal
            Aviation Administration (the "FAA") the following described
            instruments at the respective times listed below: the Lease and
            Lease Supplement with respect to the Aircraft, which Lease and Lease
            Supplement were filed at ___ p.m., C.D.T.

      Based on our examination of the above described instruments and of such
records of the FAA as we deemed necessary to render this opinion, it is our
opinion that:

      1.    the Lease is in due form for recordation by and has been duly filed
            for recordation with the FAA pursuant to and in accordance with the
            provisions of the Transportation Act;

      2.    the Airframe is duly registered in the name of the Lessor pursuant
            to and in accordance with the provisions of the Transportation Act;

<Page>

      3.    the Aircraft is free and clear of liens and encumbrances of record
            except as created by the Lease;

      4.    the rights of the Lessor and the Lessee, under the Lease, with
            respect to the Aircraft, are perfected; and,

      5.    no authorization, approval, consent, license or order of, or
            registration with, or the giving of notice to, the FAA is required
            for the valid authorization, delivery and performance of the Lease,
            except for such filings as are referred to above.

      Since title to the Airframe originated with an AC Form 8050-2 Aircraft
Bill of Sale from EMBRAER, a foreign vendor, our opinion with respect to the
Airframe covers only that period of time subsequent to the commencement of its
United States registration on April ___, 1999.

      No opinion is expressed as to laws other than Federal laws of the United
States. In rendering this opinion, we were subject to the accuracy of the FAA,
its employees and agents, in the filing, indexing and recording of instruments
filed with the FAA and in the search for encumbrance cross-reference index cards
for the Engines. Further, in rendering this opinion we are assuming the validity
and enforceability of the above-described instruments under local law. Since our
examination was limited to records maintained by the FAA, our opinion does not
cover liens which are perfected without the filing of notice thereof with the
FAA, such as federal tax liens, liens arising under Section 1368(a) of Title 29
of the United States Code, possessory artisan's liens, or matters of which the
parties have actual notice. In rendering this opinion we are assuming that there
are no documents with respect to the Aircraft which have been filed for
recording under the recording system of the FAA but have not yet been listed in
the available records of such system as having been so filed.

                                    Very truly yours,

                                    -------------------------
