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 the
Aircraft for all purposes of this Lease.

     2.2.   TERM OF THE LEASE.

     (a)    BASIC TERM. The Basic Term of this Lease shall be sixteen and
one-half 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.

     (c)    SUPPLEMENTAL RENT. Lessee shall promptly pay (or cause to be paid)
to Lessor, or to whomever shall be entitled thereto, any and all Supplemental
Rent as the same shall become due and owing hereunder. In the event of any
failure on the part of Lessee to pay any Supplemental Rent, Lessor shall have
all rights, powers and remedies provided for herein or by law or equity or
otherwise in the case of nonpayment of Basic Rent. Interest on past due 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)    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 such account
as Lessor shall direct in a written notice to Lessee from time to time 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.

     (e)    MAINTENANCE PAYMENTS. Lessee is currently negotiating a
Power-by-the-Hour Agreement. Any Power-by-the-Hour Agreement during the Term
shall be assigned to Lessor by Lessee as additional collateral for Lessee's
obligations under this Lease and Lessee shall ensure that Lessor has a perfected
security interest in Lessee's interest in such Power-by-the-Hour Agreement. Such
collateral assignment shall be effective upon the effectiveness of the
Power-by-the-Hour Agreement; provided that Lessor shall not exercise any rights
under the assignment unless and until an Event of Default has occurred and is
continuing. The counterparty shall consent to such collateral assignment in
writing and agree that, (i) upon written notice from Lessor of the occurrence
and continuation of an Event of Default, and (ii) the assumption thereof by
Lessor or its assignee, Lessor or its assignee shall be eligible for all rights
and benefits thereunder on terms no less favorable than Lessee. At any time
during time during the Term (other than the 120-day period following the
Delivery Date) that there is not a Power-by-the Hour Agreement, Lessee shall pay
to Lessor Engine maintenance payments with respect to each Engine for each
Flight Hour that such Engine is used, including all Flight Hours on a
retroactive (to the last maintenance visit) basis so that Lessor has received
payments for each Engine equivalent to the proportional share of the cost of the
next maintenance visit for such Engine ("Maintenance Payments"). The amount of
and terms and conditions with regard to Maintenance Payments and the use and
application thereof have not been agreed by Lessee and Lessor, and Lessee and
Lessor agree to negotiate in good faith with respect thereto promptly upon the
failure of Lessee to enter into a Power-by-the-Hour Agreement within 90 days
after the Delivery Date and at any time thereafter during which a
Power-by-the-Hour Agreement is not in effect for any reason. The amount of and
terms and conditions of the Maintenance Payments shall be set forth in a Lease
Supplement and filed with the FAA. In the event that Lessor and Lessee are
unable to agree in writing on the amount of and terms and conditions of the

                                       13
<Page>

Maintenance Payments and the use and application thereof within thirty (30) days
of the date that Maintenance Payments are required under this Lease, such amount
and terms and conditions shall be determined pursuant to a determination
prepared and delivered by a nationally recognized firm of aircraft auditors
nominated by Lessor and approved by Lessee, and Lessor shall immediately notify
Lessee in writing of such nomination. The aircraft auditing firm shall make its
determination within ten Business Days following its appointment, and such
determination shall be final and binding upon the parties. The cost of such
determination shall be borne by Lessee.

<Page>

take any action or fail to take any action that would cause the Aircraft not to
remain at all times duly registered in the name of Lessor 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
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

     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 as good operating condition as on the date
     delivered by Manufacturer, ordinary wear and tear excepted, 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, which group includes one or more aircraft
     operated by a Person other than Lessee, 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. In the event of a
     change in the Maintenance Program, Lessee shall provide Lessor a copy of
     the new program specifications, certified as true and correct by Lessee,
     not later than fifteen (15) Business Days following the implementation of
     the same. The Maintenance Program shall provide for the inspection of
     corrosion and the cleaning, repair and treatment thereof in accordance with
     the corrosion treatment and correction criteria as specified by the
     FAA-approved corrosion prevention and control program applicable to Embraer
     EMB-145 aircraft. Lessee shall adopt and incorporate in the Maintenance
     Program specific measures for the control of corrosion in due conformance
     with Embraer's corrosion prevention manual, and shall carry out such work
     as may be required to comply therewith, including periodic inspections by
     penetration of fuel tanks, periodic inspection

                                       21
<Page>

     and clean-up under cargo areas, periodic treatment of all mild and moderate
     corrosion and correcting all severe or exfoliated corrosion in accordance
     with the Maintenance Program. Lessee shall incorporate into the Aircraft
     all those Airframe and Engine Manufacturer service bulletins that Lessee
     plans to adopt during the Term for the rest of its Embraer EMB-145 aircraft
     fleet. The Lessee shall not discriminate against the Aircraft in terms of
     service bulletin compliance relative to the rest of Lessee's Embraer fleet.
     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. All such records, logs and other materials
     created during the immediately preceding twelve (12) months shall be kept
     in one location on Lessee's premises and all such records, logs and other
     materials more than twelve (12) months old shall be archived by Lessee at a
     location approved by Lessor. All records, logs and other materials, as
     between Lessor and Lessee and 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, at its cost and expense, shall ensure that
the Aircraft is in compliance with all applicable Airworthiness Directives,
manufacturer's "alert" service bulletins and Federal Aviation Regulation
requirements (or the requirements of any other governmental authority having
jurisdiction over the Aircraft) which become due during the Term or are
otherwise required to be performed within six (6) months following the end of
the Term. All Airworthiness Directives shall be accomplished in accordance with
all applicable bulletins and manuals published by the Manufacturer or
FAA-approved data developed by Lessee, and in a manner consistent with similar
aircraft owned, leased or operated by Lessee. Lessee shall include with the
Manual and Technical Records all documentation necessary to establish the source
data, method of compliance, verification of accomplishment, quality assurance
and all schedules of recurring action of any Airworthiness Directive.

                                       22

     7.4.   REPLACEMENT OF PARTS. Lessee shall (or if a Permitted Sublease is in
effect, shall ensure that the sublessee), 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 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, the 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, except as otherwise provided in Section
7.6, will, at its own cost and expense, replace or cause to be replaced 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 (including a serviceability tag in the case of any
calendar-limited or life-limited parts) 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. 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, the 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, the sublessee) to a pooling or interchange
arrangement customary in the United States airline industry with other aircraft
or engines owned or leased by Lessee (or, if any Permitted Sublease is then in
effect, the 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

                                       23
<Page>

or interchange arrangement may be owned by any third party, provided that Lessee
(or, if any Permitted Sublease is then in effect, the 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, the 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, the 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. Neither the Airframe nor Engines
shall be subject to any pooling or interchange arrangement. No pooling or
interchange arrangement shall result in a change of title or registration of the
Aircraft or affect Lessor's status or title to any Part under this Lease.

     7.6.   ALTERATIONS, MODIFICATIONS AND ADDITIONS. Lessee 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 or the standards, specifications or requirements imposed by any Person
for which Lessee is utilizing the Aircraft pursuant to a code share arrangement.
All such alterations, modifications and additions shall be documented by any
applicable FAA-approved Original Equipment Manufacturer ("OEM") Service
Bulletin, OEM Master Change or FAA-approved Supplemental Type Certificate,
whichever is applicable under the Transportation Act and/or applicable FARs.
Lessee shall not, without the prior written consent of Lessor, make any
additions to or alterations or modifications (including a change in
configuration) of the Aircraft other than as expressly permitted by this Section
7.6 and shall not make any alteration, modification and/or addition expressly
permitted by this Section 7.6 without giving Lessor reasonable prior notice of
the same. Such notice shall contain a detailed description of the work scope of
such addition, alteration or modification and the name of the proposed
maintenance facility that shall complete the work, each of which work scope and
maintenance facility shall be reasonably acceptable to Lessor. Title to all
Parts incorporated or installed in or attached or added to the Airframe or an
Engine as the result of any such alteration, modification, removal or addition
shall, without further act, vest in Lessor and become subject to this Lease.
Notwithstanding the foregoing, Lessee (or, if any Permitted Sublease is then in
effect, the sublessee) may, at any time during the Term, so long as no Notified
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

                                       24
<Page>

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 original cost of all parts removed
pursuant to this sentence shall not exceed $150,000 in the aggregate. Upon the
removal by Lessee (or a sublessee pursuant to a Permitted Sublease) of any Part
as provided above, title thereto shall, without further act, vest in Lessee (or
the sublessee pursuant to a Permitted Sublease, 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 sublessee pursuant to a
Permitted Sublease) 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 shall not maintain, use, service, repair, overhaul,
operate or locate the Aircraft (or, if any Permitted Sublease is then in effect,
suffer the 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, the 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.

            (b) Lessee shall not operate or locate the Aircraft, or suffer the
Aircraft to be operated or located (or permit the Aircraft to be on the ground),
in any area excluded from coverage by any insurance 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 solely in commercial passenger
operations and only by pilots and other airmen holding valid licenses or other
necessary authorizations as may be required by applicable laws and regulations.

            (d) Lessee shall promptly pay or procure that all license fees,
registration fees, landing fees, air navigation and other similar charges of any
nature (together with any penalties, fines or interest thereon) assessed or
demanded by any governmental authority upon or with respect to the delivery,
leasing, possession, use, operation or return of the Aircraft by Lessee are

                                       25
<Page>

promptly paid, and shall immediately provide Lessor, upon Lessor's request, with
an itemized statement of all such fees and charges outstanding as of the date of
such request.

     7.8.   POSSESSION AND PERMITTED SUBLEASES.

            (a)    During the 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).
The wet lease or charter of the Aircraft (expiring before the end of the Term)
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, the 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 Notified 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, the sublessee) or purchased by Lessee (or, if any Permitted
            Sublease is then in effect, the 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 lease,
            conditional sale or other security agreement, notwithstanding the
            installation thereof on such airframe; or

                                       26
<Page>

                   (iv)  install or permit the installation of an Engine on an
            airframe owned by Lessee (or, if any Permitted Sublease is then in
            effect, the sublessee), leased to Lessee (or, if any Permitted
            Sublease is then in effect, the sublessee) or purchased by Lessee
            (or if any Permitted Sublease is then in effect, the 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 sublessee to) comply with Section 10.2 hereof in
            respect thereof.

            (c)    The rights of any sublessee or other transferee which
receives possession by reason of a transfer permitted by this Section or by
Section 13 hereof, other than the transfer of an Engine which is deemed an Event
of Loss and as to which Lessee has complied with Section 10.2, shall be subject
and subordinate to, and any sublease permitted by 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 sublease upon such repossession. No sublease shall permit the
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 sublease
had not occurred. No pooling agreement, interchange agreement, 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 action which
is required in connection with any 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 sublease and all other
actions necessary or required to preserve the right, title and interest of
Lessor in the Aircraft, Airframe and Engines shall be taken by Lessee at its
expense. Notwithstanding any provision herein to the contrary, no Permitted
Sublease permitted by Section 13 shall permit any further sub-subleasing of the
Aircraft.

     7.9.   INSIGNIA. Lessee agrees to maintain (or cause to be maintained)
adjacent to the airworthiness certificate in the cockpit of the Airframe and on
each Engine 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 or financing party,
as permitted in this Agreement. Except as provided above, Lessee will not allow
the name of any Person to be placed on the Airframe as a designation that might
be interpreted as a claim of ownership; provided that nothing herein contained
shall prohibit Lessee (or any sublessee pursuant to a Permitted Sublease) from
placing its customary colors and insignia on the Airframe.

     7.10.  INSPECTIONS BY LESSOR. At all reasonable times and on reasonable
notice to Lessee, Lessor, the Owner Participant or any financing party to
Lessor, or their respective authorized representatives, may inspect the Aircraft
and inspect and make copies of the books and records of Lessee and any sublessee
required to be maintained by the FAA relating to the

                                       27
<Page>

maintenance of the Aircraft (inspections conducted when an Event of Default or a
Default described in Section 14(a)(v) has occurred and is continuing shall be at
Lessee's cost and expense; all other inspections shall be at Lessor's, the Owner
Participant's or the financing party's sole cost and expense, as the case may
be), and shall keep any information or copies obtained thereby confidential and
shall not disclose the same to any Person, except (A) to Lessor, the Owner
Participant or any financing party to Lessor, and to any prospective transferees
(and such prospective transferee's counsel, independent insurance advisors or
other agents) who agree to hold such information confidential, (B) to Lessor's,
the Owner Participant's, and the financing party's counsel, independent
insurance advisors or other agents who agree to hold such information
confidential, or (C) as may be required by any statute, court or administrative
order or decree or governmental ruling or regulation; provided, however, that
any and all disclosures permitted by clause (C) above shall be made only to the
extent necessary to meet the specific requirements or needs of the Persons for
whom such disclosure is hereby permitted. Any such inspection of the Aircraft
shall be subject to Lessee's safety and security rules applicable to the
location of the Aircraft, shall be a visual, walk-around inspection of the
interior and exterior of the Aircraft and shall not include opening any panels,
bays or the like without the express consent of Lessee (except in connection
with a maintenance visit when a panel, bay or the like is scheduled or required
to be opened); provided that no exercise of such inspection right shall
interfere with the normal operation or maintenance of the Aircraft by, or the
business of, Lessee (or any sublessee under a Permitted Sublease). Upon receipt
by Lessee of a written request from the Owner Participant specifying that the
Owner Participant desires to have an authorized representative observe the next
scheduled maintenance to be performed on the Aircraft during the Term, Lessee
shall cooperate with the Owner Participant to enable the Owner Participant's
representative to observe such scheduled maintenance to be performed on the
Aircraft during the Term. Neither the Owner Participant nor the Lessor shall
have any duty to make any such inspection nor shall either of them incur any
liability or obligation by reason of not making such inspection. Except during
the last six (6) months of the Term or during the continuance of an Event of
Default, all inspections by the Owner Participant and its authorized
representatives or Lessor and its authorized representatives provided for under
this Section 7.10 shall, in regard to each of the Owner Participant and Lessor,
be limited to one (1) inspection of any kind contemplated by this Section 7.10
during any calendar year. In addition to any inspection provided hereunder, upon
each request of the Owner Participant, Lessee will, at the sole cost and expense
of the Owner Participant, make available to the Owner Participant an inspection
in accordance with and of the kind contemplated by this Section 7.10, but solely
for the purpose of a potential transfer of the Owner Participant's interest in
the Aircraft.

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 (including the Manuals and Technical

                                       28
<Page>

Records) 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. Lessor shall file such instruments at the expense of
Lessee.

     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 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 shall 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 required by this Lease.

     8.3.   CONDITION OF THE AIRCRAFT. The Aircraft, all Parts and components at
the time of return to Lessor shall be in full compliance with all provisions of
Exhibit H hereto.

     8.4.   INSPECTION; MAINTENANCE.

     (a)    During the last six (6) months of the Term, upon 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.

                                       29
<Page>

     (b)    With respect to the last maintenance check or shop visit for the
Aircraft or any Engine, as the case may be, prior to the end of the Term, Lessee
shall comply with any reasonable request of Lessor in regard thereto, including
a request by Lessor to change the scope of work to be performed; provided,
however, Lessor shall be responsible for any incremental cost resulting directly
from any such request to change or otherwise alter the scope of work beyond that
which would otherwise be required to be performed under this Lease during such
maintenance check or shop visit, as the case may be, and Lessee shall not be
obligated to pay Rent for any additional time after the Term that is
attributable to the time required to perform such work.

     8.5.   ACCEPTANCE. Upon satisfactory completion of the operational check
flight(s), if any, and after Lessee has corrected the Discrepancies as required
to comply with this Section 8, 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 8.6, 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.

     8.6.   EXTENSION OF TERM DUE FOR DISCREPANCY CORRECTION. Should redelivery
of the Aircraft and the Manuals and Technical Records from Lessee to Lessor be
delayed (which delay shall be deemed to have occurred until Lessee shall have
complied with all of the return conditions set forth in this Section 8 with
respect to the Aircraft) beyond the date required by the terms of this Lease for
any reason other than as specified in Section 8.4, all of Lessee's obligations
under this Lease with respect to the Aircraft will remain in full force and
effect, including, without limitation, the obligation to pay Rent (including
Basic Rent at the greater of Fair Market Rental Value or the average Basic Rent
paid by Lessee during the Basic Term) hereunder with respect to the Aircraft. If
the condition of the Aircraft and the Manuals and Technical Records do not
comply with this Section 8 and Exhibit H, Lessee will, at its sole cost and
expense, diligently proceed to rectify any defect or non-compliance as promptly
as practicable (and in any event within thirty (30) days) to Lessor's reasonable
satisfaction; and the Term will be automatically extended and this Lease will
remain in full force and effect as provided above with respect to the Aircraft
until the date on which such defect or non-compliance has been so rectified;
provided, however, that if Lessee is unable to complete such rectification
within such 30-day period despite having diligently attempted to do so and
Lessee promptly notifies Lessor of such inability, the 30-day period shall be
extended for so long as necessary to complete such rectification, up to a
maximum of 60 additional days (the "Rectification Period"). If Lessee shall not
have rectified any such defect or non-compliance within the Rectification
Period, Lessee shall, upon Lessor's request given on or after the expiration of
such period, redeliver the Aircraft and the Manuals and Technical Records to
Lessor and Lessor shall, at Lessee's sole expense, diligently proceed to rectify
such defect or non-compliance to Lessor's reasonable satisfaction and the
applicable Term will be automatically extended and this Lease will remain in
full force and effect as provided in this Section 8.6 until the date on which
such defect or non-compliance has been so rectified.

     8.7.   OWNERSHIP. Any documents, equipment and any other items returned to
Lessor pursuant to this Section 8 that are not already owned by Lessor shall
thereupon become the property of Lessor.

     8.8.   DISPUTES REGARDING RETURN CONDITION. Any dispute between Lessor and
Lessee regarding the condition of the Airframe or any Engine arising under this
Section 8 or Exhibit H 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 commercially reasonable efforts to obtain a final
resolution of the dispute under the foregoing procedures within 30 days
following the date on which the dispute arises.

     8.9.   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 for up to 180 days 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 cooperate with Lessor in obtaining such insurance.

SECTION 9.  LIENS.

     9.1.   PERMITTED LIENS. Lessee 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

(or, if any Permitted Sublease is then in effect, the sublessee) 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 interest therein or any risk of
material liability (other than for payment of the amount), or any risk of
criminal penalties being imposed on any Indemnitee and so long as adequate
reserves therefor have been established, (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, the
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), or any risk of criminal

                                       31

and (viii) any Lien with respect to which Lessee (or, if any Permitted Sublease
is then in effect, the 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.

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

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 as the Airframe to
be replaced thereby, or an improved make and model, and such Replacement Engines
to be covered by a Power-by-the-Hour Agreement satisfactory to Lessor if the
Aircraft was subject to a Power-by-the-Hour Agreement at the time of the Event
of Loss; 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 promptly pay on
the third Business Day after the

                                       32

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 under the Operative Documents, 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.

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 (other than with respect to any insurance
maintained by Lessor, the Owner Participant or their Affiliates); and (iv)
provided no Notified Default has occurred and is continuing, 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:

such transfer, and (d) Lessee (or, if any Permitted Sublease is then in effect,
the 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

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) and 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).
Prior to any such conveyance,

                                       35
<Page>

Lessee (or, if any Permitted Sublease is then in effect, the 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 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) at Lessor's request,
furnish an appraisal of an independent appraiser selected by Lessor in form and
substance reasonably satisfactory to Lessor evidencing compliance with the

substitute engine, (e) 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, (f) assign to Lessor the
benefit of all assignable manufacturer's and vendor's warranties with respect to
the replacement engine, and (g) assign to Lessor any Power-by-the-Hour Agreement
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 (as to the absence of Lessor Liens only) 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 (other than with respect to insurance maintained by Lessor, the
Owner Participant or their Affiliates), 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 Notified 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 any other
amounts not already paid by Lessee, or, to the extent 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

                                       36
<Page>

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.

       (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 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 a Notified 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. 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 instrumentality or agency of any thereof which is
backed by the full faith and credit of the United States government, Lessee
shall promptly 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 sublessee) unless a Notified Default has occurred and is
continuing; 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.
In the event of the requisition for use of an Engine (but not the Airframe) by
the United States government or any agency or instrumentality of any thereof
which is backed by the full faith and credit of the United States government,
Lessee shall replace such Engine hereunder by complying (or causing any
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, unless a Notified Default has occurred and is continuing
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 Notified Default has occurred
and is continuing, either pay any insurance

                                       37
<Page>

proceeds received by it to Lessee (or, if any Permitted Sublease is then in
effect, the 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).

SECTION 11. INSURANCE.

    11.1.  INSURANCE REQUIREMENTS. On or before the Delivery Date and throughout
the Term, Lessee shall, without cost or expense to Lessor, obtain, maintain and

    hereof, to the extent that such indemnification is insurable under Lessee's
    liability policy;

           (f)     be of the type usually carried for aircraft similar to the
    Aircraft and covering risks of the kind customarily insured against by
    commercial airline companies that are engaged in the same type of scheduled
    airline business in the United States as Lessee;

           (g)     be primary and without right of contribution from other
    insurance which may be available to or carried by any Additional Insured (or
    by Lessee in its capacity as sublessor);

                                       39
<Page>

           (h)      provide that Lessor shall have no liability for premiums,
    commissions, calls or assessments with respect to such policies;

           (i)     provide in the case of the insurance required by Sections
    11.1(a)-(b) that (A) so long as no Notified Default has occurred and is
    continuing, if the amount of proceeds is less than Five Hundred Thousand
    ($500,000), such proceeds shall be payable to Lessee (or, if a Permitted
    Sublease is then in effect, the sublessee); and (B) if the amount of
    proceeds equals or exceeds Five Hundred Thousand Dollars ($500,000) or the
    proceeds are in respect of an Event of Loss with respect to the Airframe,
    such proceeds shall be payable to Lessor; and (C) if a Notified Default has
    occurred and is continuing, any loss, regardless of the amount, shall be
    payable to Lessor and held by Lessor for so long as such Notified Default is
    continuing, as security for the obligations of Lessee hereunder;

           (j)     provide that if the insurers cancel such insurance, or any
    part thereof, or 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, in the case of war risk and
    allied perils coverage) after receipt by Lessor of written notice by such
    insurers;

           (k)     expressly provide that all of the provisions thereof, except
    the limits of liability, shall operate in the same manner as if a separate
    policy covered each insured;

           (l)     include a United States service of suit clause with respect
    to insurers not domiciled within the United States;

           (m)     be effective with respect to both domestic and international
    operations; and

           (n)     contain a waiver of any right of the insurers to any 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);

           (o)     in the case of war risk and allied perils insurance, contain
    a "50-50 provision" endorsement that provides that where a loss occurs and
    it is not clear whether the loss is covered under the hull or war-risk
    coverage, the underwriters of each policy shall each fund 50% of the
    adjusted loss until such time as the cause of the loss is determined; and

           (p)     provide that all losses in excess of $500,000 shall be
    adjusted by Lessor. Lessor shall keep Lessee fully informed of, and shall
    consult in good faith with Lessee regarding, all matters and developments
    relating to any such adjustment.

                                       40
<Page>

    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, except as
provided in Section 11.2(i), be applied as follows provided no Notified Default
has occurred and is continuing (for so long as a Notified 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 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 the Airframe, so much of such payments
    remaining after reimbursement of Lessor for reasonable costs and expenses as
    shall not exceed the Stipulated Loss Value shall be applied in reduction of
    Lessee's obligation to pay such amount to the extent not already paid by
    Lessee, and to reimburse Lessee to the extent 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)     Notwithstanding the foregoing, if such payments are received
    with respect to the Airframe or the 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 costs and expenses shall be paid over to Lessor, and upon
    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 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, the
sublessee's) relevant insurance policies, a report signed by Lessee's (or, if
any Permitted Sublease is then in effect, the 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, including,
without limitation, a list of insurers, the quota share (if more than one
insurer) for each insurer, the policy numbers, and the policy expiration dates.

                                       41
<Page>

Lessee shall (and shall cause any 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 undertake 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, the 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. Lessee shall have the right to
self-insure by way of deductible, premium adjustment or otherwise, but in no
case shall the aggregate amount of self-insurance with respect to all of the
aircraft in the Lessee's fleet (including, without limitation, the Aircraft)
exceed during any policy year the lesser of (i) [*] of the highest replacement
value of any one aircraft in the Lessee's fleet or (ii) [*], 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. In no case shall the amount of
self-insurance (including deductibles) during any policy year with respect to
the Aircraft exceed [*] unless Lessee provides a report from an independent
firm of insurance brokers reasonably satisfactory to Lessor confirming that any
higher deductible amount maintained by Lessee does not exceed the amount
maintained by similar U.S. airlines operating similar equipment under a program
applicable to all aircraft in Lessee's fleet; provided that in such case there
shall be no other self-insurance with respect to the Aircraft other than such
deductible.

SECTION 12.  INDEMNITIES.

    12.1   GENERAL INDEMNIFICATION.

    (a)    Lessee hereby assumes liability for, and does hereby agree, and shall
require any 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 and whether or not indemnified by any other Person (collectively,
"Expenses") imposed on, incurred or suffered by, or asserted against any
Indemnitee, in any way relating to, based on or arising out of:

                                       42

           (i)     the Operative Documents and any other document entered into
    in connection with this Lease or any 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,

    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 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 the Operative Documents,
    whether or not such ordering, purchase, documentation, importation,
    exportation, acceptance or rejection, manufacture, construction, design,

    for use, merchantability, ownership, improving, insuring, titling or

    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 the Operative Documents, 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 sublessee
    to perform, observe or comply with any of the terms of the Operative
    Documents, or the falsity or inaccuracy of any representation or warranty of
    Lessee under the Operative Documents or any other instrument or agreement
    executed in connection with this Lease which falsity has a material and
    adverse effect on the Indemnitee;

           (iv)    the enforcement by Lessor of the terms of the Operative
    Documents; or

           (v)     the ongoing trustee fees of Lessor during the Term.

    (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

                                       43
<Page>

United States or any international authority, shall be equal to the amount of
such Expense. If any Indemnitee shall actually realize a tax savings by reason
of any Tax paid or indemnified by Lessee pursuant to this Section 12.1(b) and
such savings is not otherwise taken into account in computing such payment or
indemnity, such Indemnitee shall pay to Lessee an amount equal to the lesser of
(i) the amount of such tax savings realized, or (ii) the amount of all payments
pursuant to Section 12.1(a) by Lessee to such Indemnitee (less any payments
previously made by such Indemnitee to Lessee pursuant to this Section 12.1(b)).

    (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 (other than any claim against another Indemnitee or against any
insurance maintained by an Indemnitee).

    (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 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. Notwithstanding the foregoing,
Lessee shall not be entitled to assume responsibility for or participate in or
be consulted with respect to any action, suit or proceeding if (i) such
proceeding will involve a material risk of the sale, forfeiture or loss of, or
creation of any Lien on, the Aircraft or any part thereof unless in such event
Lessee shall have posted a bond or other security reasonably satisfactory to the
affected Indemnitees in respect of such risk, or (ii) such action, suit or
proceeding could, in the good faith opinion of the Indemnitee, entail any risk
of criminal liability, or (iii) in the written opinion of counsel to the
Indemnitee, an actual or potential conflict of interest exists and it is
advisable for such Indemnitee and Lessee to be represented by separate counsel.
In all cases in which Lessee is entitled to and has assumed the defense of a
claim, the Indemnitee may participate at its own expense with its own counsel in
any action, suit or proceeding defended by counsel selected by Lessee pursuant
to the preceding provisions.

                                       44
<Page>

    (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 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 or willful misconduct imputed
           to such Indemnitee by reason of its interest in the Aircraft);

               (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 any such disposition occurring after an
           Event of Default or a Default under Section 14(a)(v) has occurred and
           is continuing;

               (iv)   acts or events that occurred or failed to occur after the
           expiration of the Term and the return of possession of the Aircraft
           to Lessor in accordance with the terms of this Lease;

               (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;

               (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 exclusively as set forth in Section 12.3 and the
           Tax Indemnity Agreement; or

                                       45
<Page>

               (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.

    (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, foreign government 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, re-delivery, non-delivery,
acceptance, rejection, operation, leasing, re-leasing, possession, control, use,
maintenance, replacement, repair, rebuilding, modification, insuring,
registration, re-registration, de-registration, titling, licensing, inspection,
financing, refinancing, documentation, importation, exportation, transfer of
title, transfer of registration, imposition of any Lien (or the occurrence of
any liability to refund or pay over any amount as a result of a 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) the Operative Documents, including this Lease and the Lease Supplement
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, foreign government or governmental
subdivision of a foreign country, or any territory or possession of the United
States or any international authority, shall be sufficient to hold such
recipient of the payment or indemnity harmless on an after-tax basis; provided,
however, the amount of such additional payment or indemnity shall be reduced by
the net reduction in Tax, if any, that may be realized by such recipient by
reason of the payment or indemnity. 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 12.10 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.

                                       46
<Page>

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

               (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
           such Income Tax (A) 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 operation, registration, location, presence, rental 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 sublessee in such jurisdiction, and (B) exceeds the
           amount of Income Tax for which the Indemnitee would otherwise have
           been actually 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 in a transaction, 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 while an Event of Default or a Default
           under Section 14(a)(v) has occurred and is 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 this Lease if no Event of Default is existing at the time of
           return;

               (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;

               (f) Taxes imposed on the Owner Participant and indemnified under
           the Tax Indemnity Agreement;

                                       47
<Page>

               (g) any Taxes that would not be incurred but for the failure of
           an Indemnitee to exercise its contest rights as and to the extent
           required hereunder; or

               (h) 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, unless such failure is attributable to the
           failure of Lessee to provide all information required to be provided
           under the Lease.

    12.5.  CONTESTS. If a taxing authority makes a written claim 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 provide such notice to Lessee 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 after-tax, 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 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

                                       48
<Page>

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 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

                                       49
<Page>

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 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. Subject in all respects to the exceptions set forth in
Section 12.4, 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.

                                       50

    12.12. SURVIVAL. The provisions of this Section 12 shall survive
termination of this Lease.

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 sublease or otherwise
transfer its interest in all or any part of the Aircraft and any assignment or
transfer not permitted hereunder shall be void AB INITIO. No assignment,
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 sublessee under a Permitted Sublease 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 six (6) months by its term
(including any renewal rights) shall be assigned to 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 America or a state
thereof, or the District of Columbia, and a "citizen of the United States" as
defined in 49 U.S.C. Section 40102(a)(15) of the Transportation Act, (ii) shall
be a U.S. Air Carrier, (iii) shall have (unless Lessee is the survivor), by
agreement in writing, which shall be in form and substance reasonably
satisfactory to Lessor, expressly assumed the due and punctual payment of the
Rent and other sums due and to become due under the Operative Documents and the
due and punctual performance and observance of all the covenants and provisions
of the Operative Documents, 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 the greater of (x) Lessee's tangible net worth as of
the date hereof and (iii) Lessee's tangible net worth as of the date preceding
the sale, merger or consolidations.

    13.2.  PERMITTED SUBLEASES. After the earlier to occur of the tenth
anniversary of the Delivery Date or the termination of and failure to
immediately replace any code share agreement applicable to the Aircraft,
provided that no Notified Default has occurred and is continuing, Lessee may,
during the Basic Term, with the prior consent of Lessor, such consent not to be
unreasonably withheld or delayed, enter into a Permitted Sublease with respect
to the Aircraft to any Permitted Sublessee if:

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

                                       51
<Page>

    (b)    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 "citizen of the United States" as defined in the
Transportation Code (or enters into a voting trust agreement , voting powers
agreement or other similar arrangement in form and substance reasonably
satisfactory to Lessee, it being agreed that the Trust Agreement is acceptable
to Lessee), (ii) has a net worth of not less than $20,000,000 (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 an Affiliate
thereof. The provision of this Section 13.3(a) shall not apply to any transfer
or assignment if an Event of Default or a Default under Section 14(a)(v) has
occurred and is continuing. Lessee agrees that upon any transfer pursuant to
this Section 13.3(a), the transferor thereupon shall be relieved of all its
obligations hereunder and the transferee shall succeed to all of Lessor's
rights, interests and obligations under this Lease as though the transferee had
been the Lessor hereunder.

    (b)    Lessor may encumber the Aircraft or this Lease or assign its
interest or any part thereof under this Lease to a lender as security for the
purpose of financing its interest in the Aircraft and Lease. Such assignee shall
not be required to perform any duty, covenant or condition required to be
performed by Lessor under this Lease.

    (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

                                       52
<Page>

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. Unless an Event of Default or a Default under Section 14(a)(v) has
occurred and is continuing, Lessor shall pay all costs and expenses incurred in
connection with any such transfer, assignment or encumbrance, including those of
Lessee, unless such transfer, assignment or encumbrance is during the
continuation of an Event of Default or a Default under Section 14(a)(v). Lessee
agrees to cooperate in all reasonable respect in connection with Lessor's
transfer or assignment of the Aircraft and this Lease or any interest therein,
and agrees to promptly provide such acknowledgments, agreements, consents,
estoppels or other documents as reasonably requested by Lessor in connection
therewith and agrees to provide any information relating to the financial
condition or business or operations of Lessee and such other information as
Lessor may reasonably request.

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 days after the same shall have become
     due;

           (ii)   Lessee shall fail to make any other payment required hereunder
     or under any Operative Document executed by Lessee in respect hereof within
     ten days after written notice that such amount was not paid when due;

           (iii)  Lessee shall have failed to perform or observe (or caused to
     be performed and observed) in any material respect any other covenant or
     agreement hereunder or under the Lease Supplement, or in any other
     Operative Document or document or certificate furnished by Lessee in
     connection herewith or therewith or pursuant hereto or thereto (other than
     those expressly referenced in this Section 14(a) for which cure periods, if
     any, are set forth therein) and such failure shall continue unremedied for
     a period of thirty (30) days after written notice thereof by Lessor, unless
     such failure is not reasonably capable of being corrected within 30 days,
     in which case Lessee shall not be in default for so long as Lessee
     diligently commences and continues to diligently to correct such failure,
     provided that Lessee shall in all events be in default if Lessee does not
     remedy such failure within ninety (90) days after receipt of such notice;

                                       53
<Page>

           (iv)   Any representation or warranty (other than tax representations
     in the Tax Indemnity Agreement) set forth herein or in any certificate or
     document furnished by Lessee shall prove to have been incorrect in any
     material respect when made;

           (v)    the commencement of an involuntary case or other proceeding in
     respect of Lessee (or, if a Permitted Sublease is then in effect, of the
     sublessee) under the federal bankruptcy laws, as now constituted or
     hereafter amended, or any other applicable federal or state bankruptcy,
     insolvency or other similar law in the United States, or seeking the
     appointment of a receiver, liquidator, assignee, custodian, trustee,
     sequestrator (or similar official) of Lessee (or, if a Permitted Sublease
     is then in effect, the sublessee) or for all or substantially all of its
     property, or seeking the winding-up or liquidation of its affairs and the
     continuation of any such case or other proceeding undismissed and unstayed
     for a period of 60 consecutive days, or an order, judgment or decree shall
     be entered in any proceeding by any court of competent jurisdiction
     appointing without Lessee's (or the sublessee's) consent, a receiver,
     trustee or liquidator of Lessee (or the sublessee) or for all or
     substantially all of its property, and any such order, judgment or decree
     shall remain in force and unvacated for a period of 60 consecutive days
     after the date of entry;

           (vi)   the commencement by Lessee (or, if a Permitted Sublease is
     then in effect, the sublessee) of a voluntary case or proceeding under the
     federal bankruptcy laws, as now constituted or hereafter amended, or any
     other applicable federal or state bankruptcy, insolvency or other similar
     law in the United States, or the filing of an answer or petition seeking
     reorganization in a proceeding under any such laws or the filing of an
     answer admitting the material allegations of a petition filed against
     Lessee (or sublessee) in any such proceeding or the consent by Lessee (or,
     if a Permitted Sublease is then in effect, the sublessee) to the
     appointment of or taking possession by a receiver, liquidator, assignee,
     trustee, custodian, sequestrator (or other similar official) of Lessee or
     for all or substantially all of its property, or the making by Lessee (or,
     if a Permitted Sublease is then in effect, the sublessee) of any assignment
     for the benefit of creditors or the taking of any corporate action by
     Lessee to authorize any of the foregoing or to authorize a general payment
     moratorium;

           (vii)  Lessee shall fail to procure, carry and maintain on or with
     respect to the Aircraft (or cause to be procured, carried and maintained)
     insurance required to be maintained in accordance with the provisions of
     Section 11 hereof;

           (viii) Lessee shall attempt to sell or alienate the Aircraft or any
     part thereof except in compliance with the provisions of this Lease; and

           (ix)   Lessee shall cease to be a Citizen of the United States or an
     "air carrier" within the meaning of Section 40102(a)(2) of the
     Transportation Act; and

           (x)    Lessee suspends all or substantially all of its commercial
     airline operations or the franchises, concessions, permits, rights or
     privileges required for the conduct of the

                                       54
<Page>

     business and operations of Lessee are revoked, cancelled or otherwise
     terminated, or the free and continued use and exercise thereof is curtailed
     or prevented, and as a result thereof the preponderant business activity of
     Lessee ceases to be that of a commercial airline.

           (xi)   judgment for the payment of money in excess of $1,000,000 is
     rendered against Lessee and the same shall remain undischarged for a period
     of thirty (30) days during which execution of such judgment shall not be
     effectively stayed or an attachment or other Lien shall be issued against
     any of the property of Lessee for an amount in excess of $1,000,000 and
     shall remain undischarged or unbonded for thirty (30) days; and

           (xii)  Lessee shall be in default with respect to any indebtedness
     for borrowed money in an amount in excess of $1,000,000 or under any
     aircraft operating lease if the total unpaid amount payable thereunder
     exceeds $1,000,000, if the creditor or lessor thereunder causes the
     acceleration of such indebtedness or the termination of such aircraft
     operating lease.

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 any
Event of Default described in Section 14(v) or Section 14(vi); and at any time
thereafter, so long as any 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 mandatory 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 (or is believed to be 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, lien holder 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);

                                       55
<Page>

           (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 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 sublessee and without any duty to account to Lessee
    or any 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, Owner Participant or their
    Affiliates 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 sale to the date of actual payment of such amount;

           (d) In lieu of exercising its rights under Section 15.1(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 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;
    and

           (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.  CUMULATIVE REMEDIES. 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 covenants to furnish to Lessor such information concerning the
business, assets and financial condition of Lessee as Lessor may reasonably
request and, without request, furnish to Lessor:

               (i)  within forty-five (45) days of the end of each fiscal
        quarter, Lessee's financial statements for such quarter and the fiscal
        year to date prepared in accordance with generally accepted accounting
        principles set forth in the opinions and pronouncements of the
        Accounting Principles Board of the American Institute of Certified
        Public Accountants and statements and pronouncements of the Financial
        Accounting Standards Board that are applicable to the circumstances as
        of the date of determination ("GAAP");

               (ii)  within ninety (90) days of the end of each fiscal year, a
        copy of the audited annual report and accompanying consolidated
        financial statements of Lessee prepared in accordance with GAAP,
        certified by Lessee's independent accountants, and accompanied by a

        investigation and inquiry, no Default has occurred and is continuing
        hereunder; and

                                       57

               (iii) as soon as possible after any Responsible Officer has
        knowledge of the occurrence of a Default, notice to Lessor thereof.

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 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 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. 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, other than 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.

                                       59

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, 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 demand. No such
payment or performance by Lessor shall be deemed to waive any 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 so long as no
Notified Default has occurred and is continuing, 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 the occurrence and during the continuation of (i) any
Notified Default, all amounts payable shall be paid to and held by Lessor, until
such time as such Notified Default is no longer continuing, and (ii) 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.
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 that 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

                                       60
<Page>

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  RENEWAL OPTIONS. 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 Notified Default has occurred and is continuing
at the time of the notice and the commencement of the Renewal Term; provided,
however, that Lessee shall not have the right to extend the Term unless the term
of the Residual Value Guaranty also is extended for a corresponding period in a
manner reasonably acceptable to Lessor. The Basic Rent payable during each
Renewal Term under this Section 22.1 shall be equal to the Fair Market Rental
Value, and shall be paid in advance on the Rent Payment Dates.

     22.2  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 better of (i) the actual condition of the Aircraft, or
(ii) the condition of the Aircraft assuming that it is in the condition in which
it is required to be maintained and further assuming half-life condition. The
Fair Market Rental Value shall be determined by mutual written agreement or, in
the absence of mutual written agreement within 30 days following Lessee's
extension notice, pursuant to the appraisal procedure described in Section 23.3.

SECTION 23. PURCHASE OPTIONS.

     23.1  PURCHASE OPTIONS. Provided that no Notified Default has occurred and
is continuing on the date of purchase by Lessee, Lessee shall have the right to
purchase the Aircraft (i) upon the Purchase Option Date, for a purchase price
equal to the amount specified on

                                       61
<Page>

Schedule I, (ii) upon termination of the Basic Term, for a purchase price equal
to the then Fair Market Sales Value of the Aircraft (but under no circumstance
less than the Lease Support RVG Level set forth in the Residual Value Guaranty);
or (iii) 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, 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 or which survive the Term of this Lease) 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), Section 23.1(ii) or
Section 23.1(iii), 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 following the determination of the Fair Market Sales Value. In the event
that Lessee exercises its right of revocation, at the option of Lessor, the Term
of this Lease shall be extended to a date that is not earlier than 180 days
following the notice of revocation and Basic Rent during such extension period
shall be equal to 110% of the Basic Rent immediately prior to such extension.

     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 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 within 30 days
following Lessee's option exercise notice, 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 Notified Default has occurred and
is continuing, Lessee shall have the right during the Basic Term on at least 180
days prior written notice, to terminate this Lease by written notice from its
Chief Financial Officer to Lessor to the effect that the Aircraft has become
obsolete or surplus to Lessee's equipment requirements. Such notice shall
specify a proposed date of termination, which shall be a Rent Payment Date at
any

                                       62
<Page>

time on or after the seventh 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 "as is", without any warranty by Lessor except as to Lessor's
title and the absence of Lessor's Liens. (Lessor and Owner Participant may also
solicit bids directly or through agents other than Lessee and Owner Participant
may also bid.) If Lessee receives any bid acceptable to it, it shall, at least
10 Business Days prior to the proposed date of sale thereunder, certify to
Lessor in writing the amount and terms of such acceptable bid, the proposed date
of sale and the name and address of the potential buyer. Lessee may, by notice
to Lessor, withdraw its notice of termination at any time on or before the
proposed Termination Date, and thereupon this Lease shall continue in full force
and effect. Lessee may withdraw notice of termination not more than twice during
the Term. On the Termination Date or such other date of sale as shall be
consented to by 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 acceptable cash Dollar
bid (net of brokerage commissions) to close such sale and purchase of the same
(which shall not be Lessee or any Affiliate of Lessee or any Person with whom
Lessee or its Affiliates has any arrangement or understanding regarding the
future use of the Aircraft ), 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 to the Airframe and the Engines
or engines conveyed to Lessor as provided in Section 10 to such party, in
"as-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 shall transfer to Lessee, in "as-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. Lessor shall retain the total selling price realized at any
sale of the Airframe and Engines or engines installed thereon in accordance with
this Section 24. In addition, on the Termination Date, Lessee shall pay to
Lessor in immediately-available funds, an amount equal to the sum of (i) the
excess, if any, of the sum of the Stipulated Loss 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; plus (v) in the
event that at the time of delivery by Lessee pursuant to Section 24.1, the
Aircraft fails to satisfy the applicable provisions of Section 8 and Exhibit H,
an amount (which shall constitute Lessor's sole and exclusive remedy against
Lessee in respect of any such failure) equal to the Equivalency Payment that
would be due from Lessee to Lessor under Section 6 of Exhibit H if the Aircraft
had been returned to Lessor in such condition.

                                       63
<Page>

     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 Basic
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. Section 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 that would not preserve such benefits or render
them doubtful. To the extent consistent with the provisions of 11 U.S.C. Section
1110 or any analogous section of the Federal bankruptcy laws, as amended from
time to time, it is hereby expressly agreed and provided that, 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 affected by the
provisions of 11 U.S.C. Section 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.

SECTION 27. CHOICE OF LAW; CONSENT TO JURISDICTION.

     27.1. GOVERNING LAW. This Lease shall be governed by and construed in
accordance with the laws of the State of New York, without regard to or
application of its conflict of laws rules.

                                       64
<Page>

     27.2  CONSENT TO JURISDICTION. Each of Lessee and Lessor voluntarily
submits itself to the non-exclusive jurisdiction of the state and federal courts
situated in New York, New York for any dispute arising hereunder. Each of Lessee
and Lessor hereby irrevocably waives any objection which it may now or hereafter
have to 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 Operative Document, 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 encompass 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.

                                           Re:  CHAUTAUQUA AIRLINES, INC.

Ladies and 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 May 18, 2000, between First Security Bank, National
Association ("Lessor"), and the Corporation (the "Lessee"); (ii) a Lease
Supplement, dated as of May 18, 2000, between Lessor and the Corporation; (iii)
an Acceptance Certificate, dated as of May 18, 2000, between Lessor and the
Corporation; and (iv) a Tax Indemnity Agreement, dated as of May 18, 2000,
between TA Air XVI Corp., a Delaware

                                       iii
<Page>

corporation ("TA Air") and the Corporation (collectively, the "Lease
Documents"). Capitalized terms used but not defined herein have the meanings
given to them in the Lease.

     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) a certificate relating
to certain factual matters executed by an executive officer of the Corporation
(the "Officer's Certificate").

     In our examination of the Lease Documents 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, 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, the
Officer's Certificate 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.

                                       iv
<Page>

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

          4.  The Corporation is an "air carrier" as defined in 49 U.S. Code
Section 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, 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 Section9-402(7) of the
Uniform Commercial Code; (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 Section9-103(3)(d) of the Uniform
Commercial Code; and (vi) the taking possession by Lessor of the chattel paper
original of the Lease, 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, New York or Connecticut in order to establish and perfect the right,
title and interest of Lessor under the Lease or in and to the Aircraft.

          6.  Lessor, as lessor under the Lease, is entitled to the protection
of Section 1110 of the United States Bankruptcy Code in respect of the Lease and
the Aircraft in the event of a proceeding under Chapter 11 of the United States
Bankruptcy Code in which Lessee is a debtor.

     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 the
United States and the States of New York and Connecticut, and to the extent that
the opinions expressed herein relate to or are affected by or are dependent upon
the laws of any other jurisdictions, we have assumed, without independent
investigation, that such laws are the same as those of the States of New York
and Connecticut applied without regard to conflicts of laws principles; (b) in
rendering our opinions hereunder, we have made no independent factual
investigation other than as expressly set forth herein; (c) no opinion is
expressed as to whether any of the conditions precedent set forth in the Lease
has been satisfied; (d) our opinions as to no violation of existing law and to
the consents and approvals are based upon a review of those statutes, rules and
regulations which, in our experience, normally are applicable to transactions of
the type contemplated by the Lease Documents; and (e) 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,

                                        v
<Page>

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 Lease 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 for any purpose, or otherwise used, circulated or quoted, without
our prior written consent. This opinion is rendered as of the date hereof, and
we disclaim any undertaking to advise of any changes which may hereafter be
brought to our attention.

                                                Very truly yours,

                                       vii
<Page>

Ladies and 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 (N266SK) (the "Lease") between the Corporation and
First Security Bank, National Association ("Lessor"), dated as of May 18, 2000,
relating to the Embraer EMB-145LR aircraft bearing manufacturer's serial number
EMB 145241; Lease Supplement No. 1, dated as of May 18, 2000, between Lessor and
Lessee; an Acceptance Certificate, dated as of May 18, 2000, between Lessor and
the Corporation; and a Tax Indemnity Agreement, dated as of May 18, 2000,
between TA Air XVI, Corp. and Lessee (the Lease, the Lease Supplement, the
Acceptance Certificate and the Tax Indemnity Agreement are hereinafter
collectively referred to as the "Lessee Documents"). 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 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, 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.

     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.

                                      viii
<Page>

     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 (i) do not require stockholder
approval, and (ii) do not require any consent or approval, 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 121 of the Federal Aviation Regulations and
49 U.S. Code Section44705 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.

     5. There are no suits or proceedings, pending or threatened, against the
Corporation before any executive, legislative, judicial, administrative or
regulatory body which, if adversely determined, might, individually or in the
aggregate, 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.

Ladies and Gentlemen:

     This opinion is furnished to you pursuant to Section 5.1 of the Aircraft
Lease Agreement dated as of May 18, 2000 (the "Lease") between First Security
Bank, National Association ("Lessor") and Chautauqua Airlines, Inc. ("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 FAA Bill of Sale, the Lease and Lease Supplement with
respect to the Aircraft, and the Trust Agreement, which documents were filed at
___ p.m., C.D.T, _____, C.D.T., and _____, C.D.T., respectively.

     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 FAA Bill of Sale, Lease and Lease Supplement, and the Trust
        Agreement are in due form for recordation by and have been duly filed
        for recordation with the FAA pursuant to and in accordance with the
        provisions of the Transportation Act.

                                       xi
<Page>

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

     3. The Lessor is the owner of legal title to the Aircraft and 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.

     5. No other registration of the Aircraft and no filings or recordings
        (other than the filings and recordings with the FAA which have been
        effected) are necessary to perfect in any jurisdiction within the United
        States the Lessor's title to the Aircraft.

     6. 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 and the
        Trust Agreement, 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 ___, 2000.

     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 that 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 that 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,


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

                               RETURN CONDITIONS

     At the end of the Lease Term:

1. GENERAL CONDITIONS.

          At the time of return (the "Return Date"), the Aircraft shall (i) have
   been continuously and currently maintained in accordance with the Maintenance
   Program as authorized by the FAA, as if the Aircraft were to be kept in
   further commercial passenger service by Lessee and (ii) meet the following
   requirements:

   (a) OPERATING CONDITION - The Aircraft shall be in good operating condition,
       ordinary wear and tear excepted, with all of the Aircraft equipment,
       components, and systems functioning in accordance with their intended use
       irrespective of variations or deviations authorized by the Minimum
       Equipment List or Configuration Deviation List. All replacement
       equipment, parts, components or items installed on the Aircraft shall be
       manufactured by the original manufacturer approved by Embraer or a
       manufacturer holding requisite authority of the FAA, and in case of used,
       rotable parts, have an FAA-approved serviceable tag.

   (b) CONFIGURATION - The Aircraft shall be in the same passenger configuration
       with all equipment installed therein as the Aircraft was when delivered
       by Embraer, ordinary wear and tear excepted, including replacements and
       substitute parts and equipment. The Aircraft shall not suffer any
       modification or alteration (hereinafter "Modifications") after the date
       delivered by Embraer (the "Embraer Delivery Date") provided however that
       Lessee may make Modifications to the Aircraft as long as they are
       included as factory-installed features in EMB-145 aircraft delivered to
       the Lessee subsequent to the delivery of the Aircraft. The term
       Modifications shall be deemed to include, but not be limited to (i)
       changes to the Aircraft structure, performance, weight and balance, (ii)
       changes which materially adversely affect the Aircraft's flight

5. PROVISION FOR "POWER-BY-THE HOUR AGREEMENTS"

       If the Engines, APU, or any other hour or cycle controlled components on
the Termination Date are maintained under valid Power-By-The-Hour Agreements
(the "PBH Agreements") (and either have been maintained throughout the Lease
term under PBH Agreements, or Lessee has made payments to the maintenance
provider to cover the period in which such components were not under such PBH
Agreements), under which the Lessee is current on all payments and otherwise in
good standing, then, if, following termination of this Lease, Lessor has sold or
leased the Aircraft to an operator that has become a party to Lessee's then
existing PBH Agreements relating to the Engines, APU or other hour or cycle
controlled components, or is itself party to a similar power-by-the-hour
agreement for any of the foregoing, in each case such that the Engines, APU
and/or controlled components are eligible for continued maintenance under the
relevant PBH Agreement (or other power-by-the-hour agreement) without additional
costs, start-up charges or overhaul requirements (unless Lessee agrees to pay
and does pay all such amounts), then in lieu of the relevant requirements in
Sections 2.c, 2.d, 3, 4.a or 4.e hereof, the Lessee shall return each such
component in such condition as shall make it eligible for continued maintenance
under a PBH Agreement.

       If however, the Engines, APU, or any other hour or cycle controlled
components on the Termination Date are maintained under valid PBH Agreements as
set forth in the paragraph above but the Lessor has sold or leased the Aircraft
to an operator that has not become a party to Lessee's then existing PBH
Agreements relating to the Engines, APU or other hour or cycle controlled
components, or is itself party to a similar power-by-the-

                                      xii
<Page>

hour agreement for any of the foregoing, in each case such that the Engines, APU
and/or controlled components are eligible for continued maintenance under the
relevant PBH Agreement (or other power-by-the-hour agreement) without additional
costs, start-up charges or overhaul requirements (unless Lessee agrees to pay
and does pay all such amounts), then the provisions of this Section 5 with
respect to the Power-by-the-Hour Agreements for such Engines, APU and/or
controlled components, as the case may be, in question shall not be operative
and Lessee shall comply with Sections 2(c), 2(d), 3, 4(a) and 4(e) hereof, as
appropriate, and, on the Return Date, make any Equivalency Payments for the
affected Engines, APU and/or controlled components; provided, however, that if
the Aircraft has not been sold as of the Return Date but, within six (6) months
after the Return Date is sold or leased by Lessor to an operator that has become
a party to and succeeded to Lessee's status under such PBH Agreement(s) or has
itself become a party to another power-by-the-hour agreement such that the
Engines, APU and/or controlled components are eligible for continued maintenance
under the relevant PBH Agreement (or other power-by-the-hour agreement) without
additional costs, start-up charges or overhaul requirements (unless Lessee
agrees to pay and does pay all such amounts), Lessor shall promptly refund to
Lessee the portion of the Equivalency Payments (as defined in Section 6 hereof)
paid by Lessee that have not been incurred or expended for any maintenance,
overhaul requirements associated with any power-by-the-hour agreement) with
respect to the affected Engines, APU and/or controlled of the Aircraft.

       For the purposes hereof, a PBH Agreement shall mean a maintenance
program, provided by the Engines, APU or component manufacturer or its successor
or designee, providing full maintenance (other than routine day-to-day
maintenance; provided, that foreign-object damage and abuse may be excluded or
separately charged) for such Engines, APU and/or other components at no cost
other than standard per-cycle rates (i.e., excluding charges based on the
current maintenance status of such component), all benefits of which program,
including but not limited to the payments made by Lessee under such PBH
Agreements while operating the Aircraft, shall be assignable or otherwise
transferable to any other carrier without restrictions of any kind.

               The components of the formula above shall be as agreed between
       Lessor (or its designee) and the Lessee. If Lessor (or its designee) and
       the Lessee fail to reach agreement on any components of the above
       formula, such amount will be determined as the average price that would
       be charged by a third party to restore the Aircraft to the conditions set
       forth in the Lease and herein, based on one quotation obtained by Lessor
       (or its designee) and one quotation obtained by Lessee, both from
       reputable, FAA, Manufacturer, and Lessor (or its designee)-approved,
       EMB-145 repair station in the USA. If the prices of such quotations
       differ by more than ten percent (10%), Lessor (or its designee) and
       Lessee shall obtain a third quotation from a another reputable, FAA,
       Manufacturer and Lessor (or its designee)-approved, EMB-145 repair
       station in the USA, the quotation which is farthest from the average of
       all three quotations shall be disregarded and the average of the two
       remaining quotations shall be binding upon Lessor (or its designee) and
       Lessee as the components of the formula.

   (c) The Equivalency Payment for each return condition of each Adjustable Item
       in the relevant section referred to in the first paragraph of this
       Section 6, whether positive or negative, shall be aggregated in order to
       determine the total Equivalency Payment due from Lessee. (For
       clarification, items in more than the required condition shall be netted
       against items in less than the required condition when determining the
       amount of the total payment due, provided however that such netting is
       only applicable to the following major components: Engines, APU and
       landing gear). If the cumulative Equivalency Payment after such netting
       is negative, it shall be deemed to be zero.

   (d) In no event shall the Equivalency Payment due from the Lessee to Lessor
       exceed the aggregate amount of any payment and expenses that Embraer may
       make under the Residual Value Guaranty.

   (e) Notwithstanding the equivalency charges that may be otherwise payable or
       available under this Section 6, if:

       (i)   Any installed Engine has completed more than 3,750 flight hours
             since new or since its last full performance restoration shop visit
             at which it was subject to a full engine management program rework
             (or less than twenty-five percent (25%) of the on-wing hours
             remaining in accordance with an amended RR Allison shop workscope
             guide),

       (ii)  Any Engine life limited part has a remaining useful life until the
             next scheduled replacement of less than twenty five percent (25%),

       (iii) The APU has remaining less than twenty five (25%) of the expected
             mean time before removal;

       (iv)  The main landing gear or the nose landing gear has less than twenty
             five percent (25%) of the cycles remaining prior to removal for
             overhaul, or the cycles exceed one hundred and ten percent (110%)
             of the airframe, or

       (v)   The brakes have less than the C check brake wear limits with the
             brakes set at normal parking brake pressure, or the tires have a
             remaining useful life of less than twenty five percent (25%),

                                       xv
<Page>

       then, in any such case, Lessee shall, at its own cost and expense,
   overhaul, refurbish and/or replace each non-complying item so that it meets
   the applicable level specified in items (i) through (v) above.

7. INSPECTION UPON RETURN

       Lessor (or its designee) shall have the right to inspect the Aircraft
   upon return, and the following conditions shall apply:

   (a) GROUND INSPECTION - The Aircraft including the Aircraft Documentation
       shall be made available to Lessor (or its designee) for ground inspection
       by Lessor (or its designee) at Lessee's facilities. Such inspection shall
       commence no later than fourteen (14) Business Days prior to the date of
       return of the Aircraft. Lessee shall remove the Aircraft from scheduled
       service and open the areas of the Aircraft as required to perform the
       necessary checks as specified in Section 2 hereof. In addition, Lessee
       shall allow Lessor (or its designee) to accomplish its inspection to
       determine that the Aircraft, including the Aircraft Documentation are in
       the condition set forth in Section 1, 2, 3 and 4 hereof. During such
       checks, Lessor's (or its designee's) personnel shall have the right to
       reasonably request that adjacent additional panels or areas be opened in
       order to allow further inspection by Lessor's (or its designee's)
       personnel.

   (b) OPERATIONAL GROUND CHECK - Lessee shall conduct an operations ground
       check on the Aircraft in accordance with the Maintenance Program manual
       criteria for the purpose of demonstrating to Lessor (or its designee) the
       satisfactory operation of the systems, including a full fuel tank leak
       check, pilot and static systems check and hydraulic system internal leak
       check.

   (c) OPERATIONAL TEST FLIGHT - After correction of any Discrepancies
       identified in Sections 7(a) or (b), the Aircraft shall be test flown by
       Lessee, using qualified flight test personnel, for the amount of time
       necessary to satisfactorily demonstrate the airworthiness of the Aircraft
       and the proper functioning of all systems and components in accordance
       with the agreed check flight procedures. During such test flight command,
       care, custody and control of the Aircraft shall remain at all times with
       Lessee. Up to five (5) of Lessor's (or its designee's) designated
       representatives (or more if mutually agreed) may participate in such
       flight as observers. Upon completion of such operational flight-testing,
       the representatives of Lessee and Lessor (or its designee) participating
       in such testing shall agree in

                                      xvi
<Page>

       writing upon any discrepancies required to be corrected by Lessee in
       order to comply with the conditions required hereunder.

   (d) If requested by Lessor (or its designee) in writing, all discrepancies
       which are noted during the inspection and acceptance flight(s) shall be
       corrected at Lessee's expense. If such discrepancies are substantiated by
       the Maintenance Program and Lessor (or its designee) determines that
       repairs, modifications or other work items are required to cause the
       Aircraft to comply with the requirements provided herein, including,
       without limitation, any maintenance required so that the Engines will
       meet all Engine parameters and trends specified by the Maintenance
       program, Lessee shall cause such repairs and other work items to be
       commenced and completed prior to return.
