applied or paid or, as the case may be, such amount so set aside, avoided or
repaid and such amount so set aside, avoided or repaid shall not be considered
as having been discharged or diminish the liability of Lessee to Lessor and the
liability of Lessee to Lessor shall continue to apply as if such payment had at
all times remained owing to Lessor and Lessee shall accordingly indemnify Lessor

investment) at the time such monies are to be paid to the Lessee or applied to
or for the benefit of the Lessee, unless an Event of Default shall have occurred
and be continuing, in which case such gains shall be held or applied in
accordance with the provisions of Section 4.07. The Lessee will promptly pay to
the Lessor, on demand, the amount of any loss realized as the result of any such
investment (together with any fees, commissions and other expenses, if any,
incurred in connection with such investment).

covenants that if at any time it appears reasonably probable that it will cease

promptly so notify, to the extent permitted by law, the Lessee.

amend, modify or supplement any other provision of the Trust Agreement in a
manner that would materially adversely affect Lessee without the prior written
consent of Lessee.

expressly permitted in Section 8.05 and in Section 5 of EXHIBIT A-2, the action
to be taken shall not affect the registration of the Aircraft and (y )

                                       24
<Page>

all necessary approvals of each Governmental Entity having jurisdiction over the
Aircraft, Lessee or other relevant Person have been obtained, then subject to
the limitations set forth in Sections 8.01(b ) and (c ), Lessee may, without the
consent of Lessor:

               (i) deliver possession of the Aircraft, Airframe or any Engine or
     any Part thereof to a Maintenance Contractor for testing or other similar
     purposes or for service, repair, maintenance, testing or overhaul work on
     the Aircraft or for alterations or modifications in or additions to the
     Aircraft to the extent required or permitted by the terms hereof;

               (ii) install any Engine on an airframe owned by Lessee free and
     clear of all Liens, except (A) Permitted Liens or those that apply only to
     the engines (other than Engines), appliances, parts, instruments,
     appurtenances, accessories, furnishings and other equipment (other than
     Parts) installed on such airframe and (B) the Lien of any mortgage that
     expressly and effectively provides that such Engine shall not become
     subject to the Lien thereof, notwithstanding the installation of such
     Engine on any airframe subject to such Lien, unless and until Lessee shall
     become the owner of such Engine;

               (iii) install any Engine on an airframe leased to Lessee or
     purchased by Lessee subject to a conditional sale or other security
     agreement; PROVIDED that (A) such airframe is free and clear of all Liens
     except the rights of the parties to the lease or conditional sale or other
     security agreement covering such airframe and except Liens of the type
     permitted by Section 8.01(a)(ii)(A) and (B); and (B) there shall be in
     effect between Lessee and such lessor or conditional vendor or other
     secured party of such airframe a written agreement (which may be the lease
     or hire purchase or conditional sale agreement covering such airframe)
     whereby such lessor or conditional vendor or other secured party expressly
     and effectively agrees that neither it nor its successors and assigns will
     acquire or claim any right, title or interest in such Engine by reason of
     such Engine's being installed on such airframe at any time while such
     Engine is subject to this Lease; and PROVIDED FURTHER, that the rights of
     any transfer permitted by this Section 8.01 shall be subject and
     subordinate to all of the terms of this Lease, including, without
     limitation, Lessee's obligation to return the Engines at the end of the
     Term and Lessor's right to repossession pursuant hereto, and Lessee shall
     remain primarily liable hereunder for the performance of all of the terms
     of this Lease to the same extent as if such transfer had not occurred;

               (iv) so long as no Specified Default shall have occurred and be
     continuing, sublease the Aircraft to any Permitted Sublessee;

               (v) enter into a charter or wet lease or other similar
     arrangement, which shall not constitute a transfer of possession hereunder
     so long as (A) no Person other than the Lessee is granted any legally
     enforceable possessory interest in the Aircraft and the Lessee retains
     operational control of the Aircraft at all times, (B) Lessee will remain
     primarily responsible for the performance of all terms of this Lease and
     the other Operative Documents, and (C) any such wet lease or other
     arrangement does not preclude Lessee from performing any of its obligations
     under this Lease;

               (vi) so long as no Specified Default shall have occurred and be
     continuing, subject any Engine to an interchange or pooling agreement
     approved by the Lessor (such approval not to be unreasonably withheld in
     the case of any such Engine interchange agreement solely among Section 1110
     Persons) and that is applicable to other similar property owned by or
     leased to the Lessee and is entered into by the Lessee in the ordinary
     course of its airline business, PROVIDED, that (A) no such agreement or
     arrangement shall under any circumstances result in, contemplate or require
     the transfer of title to any Engine and (B) if the Lessor's title to any
     Engine shall

                                       25
<Page>

     nevertheless be divested under any such agreement or arrangement, such
     divestiture shall be deemed to be an Event of Loss with respect to such
     Engine and the Lessee shall comply with Section 12.02 hereof in respect
     thereof; and

               (vii) so long as no Specified Default shall have occurred and be
     continuing, transfer possession of the Airframe or any Engine to the United
     States of America, or to a foreign government, when required by applicable
     Law (it being understood that nothing in this clause (viii) shall relieve
     the Lessee from its obligations under Section 12.01(a) if such transfer
     becomes an Event of Loss), in which event Lessee shall promptly notify
     Lessor in writing of any such transfer of possession.

     In the event that Lessee shall have entered into a mortgage, lease or
conditional sale agreement complying with the provisions of Section 8.01(a)(ii)
or (iii), Lessor hereby agrees, for the benefit of the mortgagee, lessor or
conditional vendor under such agreement, that Lessor and its successors and
assigns shall not acquire or claim, as against such mortgagee, lessor or
conditional vendor, any right, title or interest in any engine owned by such
person or in which it has a security or ownership interest by reason of such
engine's being installed on the Airframe.

          (b) LIMITATIONS ON TRANSFERS. With respect to any transfer pursuant to
     Section 8.01(a):

               (i) the rights of any transferee pursuant to a transfer or other
     arrangement permitted by Section 8.01(a) shall be subject and subordinate
     to all the terms of this Lease and to the rights of Lessor in the Aircraft
     and this Lease, PROVIDED that, in the case of a transfer pursuant to
     Section 8.01(a)(ii) and (iii), Lessee shall ensure that the lease,
     mortgage, hire purchase or conditional sale agreement pursuant to which the
     airframe on which an Engine is installed is leased or purchased by the
     Lessee contains a clause similar to the last proviso of Section
     8.01(a)(iii);

               (ii) Lessee shall remain primarily liable hereunder for the
     performance of all of the terms hereof to the same extent as if such
     transfer or other arrangement had not occurred, and no such transfer or
     other arrangement pursuant to the terms of Section 8.01(a) shall in any way
     discharge or diminish any of Lessee's obligations to Lessor hereunder; and

               (iii) Lessee shall be responsible for filing or recording all
     such instruments, including, if applicable, this Lease and an aircraft
     mortgage, as may be necessary to perfect and preserve the respective
     interests of Lessor and any Financing Party in the Aircraft and this Lease
     in the State of Registration at its sole expense, notwithstanding any
     provision of this Lease to the contrary.

          (c) LIMITATIONS ON SUBLEASES. With respect to any Sublease pursuant to
     Section 8.01(a)(iv):

               (i) Prior to the end of the Recovery Period, Lessee may not enter
     into a Sublease (A) with any Permitted Sublessee domiciled in a country
     other than the United States, (B) or with any "tax-exempt entity," within
     the meaning of Section 168(h)(2) of the Code, or (C) that would result in a
     determination by any United States taxing authority that the Aircraft will
     be treated as "used predominantly outside the United States" within the
     meaning of Section 168(g) of the Code that would result in the cost
     recovery deductions to Lessor being less than the maximum allowable to a
     United States owner of the Aircraft, unless Lessee has prepaid on a lump
     sum basis, prior to the commencement of such Sublease, an amount equal to
     any indemnity obligation

                                       26
<Page>

     of the Lessee due under the Tax Indemnity Agreement. The Country List in
     Exhibit F shall be subject to review from time to time, and Lessee may
     propose additions thereto, subject to the consent of Lessor not to be
     unreasonably withheld, and Lessor may propose deletions therefrom in its
     reasonable discretion.

               (ii) With respect to any Sublease, Lessee shall notify Lessor as
     soon as a copy of the proposed Sublease is available and in any event not
     less than 30 days prior to the execution of any such Sublease or, if later,
     the commencement of such Sublease, and together with such notice, Lessee
     will deliver promptly to Lessor a copy of such proposed Sublease and, if
     requested by Lessor, other documents reasonably related to such proposed
     Sublease and Permitted Sublessee.

               (iii) Lessee shall not enter into any Sublease unless:

                    (A) the term (including any option of the Permitted
          Sublessee to renew or extend) of any such Sublease does not continue
          beyond the end of the Term, unless (x) no Specified Default shall have
          occurred and be continuing at the commencement of such Sublease and
          (y) Lessee shall have irrevocably committed to purchase the Aircraft
          pursuant to the terms hereof;

                    (B) such Permitted Sublessee is prohibited from
          sub-subleasing the Aircraft or, except to the extent provided in
          subclause (F), otherwise assigning, granting or transferring any of
          its rights, obligations or interests with respect thereto or under the
          Sublease;

                    (C) the Sublease by its terms is expressly and effectively
          subject and subordinate to all of the terms of this Lease, and to
          Lessor's rights, powers or remedies hereunder, including Lessor's
          right pursuant to the exercise of its rights and remedies hereunder to
          avoid such Sublease and to recover the Aircraft from Lessee;

                    (D) such Permitted Sublessee is not on the effective date of
          such Sublease in default thereof in any material respect, with or
          without giving of notice or passage of time;

                    (E) if such Permitted Sublessee is domiciled in the United
          States, the Aircraft is and remains registered, and eligible for
          registration, in Lessor's name in accordance with the provisions
          hereof;

                    (F) the terms and conditions of such Sublease (1) shall not
          permit any Sublessee to perform any act not permitted to Lessee, (2)
          shall either (x) impose on the Sublessee obligations that are
          substantially the same as those contained in Sections 8.01(a)
          (PROVIDED that Sublessee may only be authorized to make the transfers
          permitted in clauses (i), (ii), ( iii ) and (v) of Section 8.01(a)),
          Section 8.01(b), Sections 8.02 through 8.08, Section 9.01, Section
          9.02(a) and (b), and Section 9.03 (PROVIDED that only pooling
          arrangements approved in advance by Lessor shall be permitted) or (y)
          permit Lessee to continue to perform its obligations thereunder, (3)
          shall provide for the inspections contemplated by Section 13.02, and
          (4) shall not delegate to Sublessee any of the obligations of Lessee
          under Article XVIII; and

                                       27
<Page>

                    (G) such Permitted Sublessee has provided evidence
          satisfactory to Lessor of insurance coverage required by Article XI
          with respect to the operation of the Aircraft by such Permitted
          Sublessee.

               (iv) Lessee may not enter into any Sublease the provisions of
     which would prevent Lessee from complying with the terms of EXHIBIT D-1 and
     EXHIBIT D-2 hereto.

               (v) In the case of any Sublease that has a term greater than one
     year (assuming that any renewal options in such Sublease are exercised), as
     security for the due and punctual payment of all Rent payable by Lessee,
     and the timely performance and observance by Lessee of all covenants made
     by it under this Lease, Lessee hereby grants to Lessor a security interest
     in all of Lessee's right, title and interest in and to any such Sublease of
     the Aircraft together with all renewals of such Sublease executed or in
     effect from time to time, and all payments, including rent, insurance
     proceeds (other than public liability insurance proceeds) and all other
     amounts due and to become due thereunder (other than indemnity payments for
     the account of Lessee) and all proceeds of the foregoing; PROVIDED, that
     Lessor shall be exclusively entitled to exercise all of Lessee's rights and
     remedies under each Sublease of the Aircraft, including the right to
     demand, collect, sue, make claims for, and otherwise be paid all rent and
     other amounts due and to become due under each such Sublease, only from and
     after the occurrence of an Event of Default hereunder.

               (vi) With respect to any Sublease that has a term longer than one
     year, such Sublease shall (A) be accompanied by a security assignment in
     form and substance reasonably satisfactory to Lessor, and (B) be filed,
     together with such security assignment and such other documents as are
     necessary to perfect, protect and preserve the security interest granted
     hereby with respect to such Sublease, with the FAA or other government of
     registry of the Aircraft, as applicable, and with the necessary state
     recording offices pursuant to the UCC, or with such other recording offices
     as are required under applicable Law, and Lessee shall take such actions as
     Lessor shall reasonably request to perfect the security interest in the
     Sublease.

               (vii) Concurrently with entering into any Sublease, Lessee shall
     give written notice to the Permitted Sublessee of Lessor's right to be paid
     such rents and Lessor's other rights with respect to the Sublease from and
     after the occurrence of an Event of Default, and Lessee and such Permitted
     Sublessee shall each acknowledge in writing that all such payments shall be
     made directly to Lessor, and as to Lessor's other rights and remedies wish
     respect thereto.

               (viii) Lessee's right to enter into any Sublease is further
     conditioned upon Lessee delivering to Lessor (A) an opinion of counsel
     (which counsel and opinion shall be reasonably satisfactory to Lessor) to
     the effect, among other things, that (1) if the country in which the
     Permitted Sublessee has its principal office and domicile is not the United
     States, such country would give effect to the title of Lessor in and to the
     Aircraft, and permit the registration of the Aircraft in the name of Lessor
     (or Lessee or Permitted Sublessee, as appropriate), and (2) if the
     Permitted Sublessee is a Section 1110 Person, an opinion of counsel that
     the Lessee as lessor is entitled to the benefits of Section 1110 (assuming
     no change in United States law which would make such benefits unavailable
     to aircraft leases generally under United States law), and (B) a notice
     stating the identity of the applicable Permitted Sublessee and stating that
     no Specified Default shall have occurred and be continuing and that such
     Sublease complies with the requirements of this Section 8.01 and to the
     knowledge of Lessee after due inquiry the applicable Permitted Sublessee is
     not then subject to a proceeding or final order under applicable
     bankruptcy, insolvency or reorganization laws.

                                       28
<Page>

               (ix) Any consolidation or merger of Lessee or conveyance,
     transfer or lease of all or substantially all of Lessee's assets permitted
     by Section 6.01 shall not be prohibited by this Section 8.01(c).

          (d) [Intentionally Omitted]

          (e) EXPENSES. Lessee hereby agrees to reimburse all reasonable out of
pocket costs and expenses of Lessor (including the reasonable fees and expenses
of counsel) incurred in connection with any re-registration of, or any Sublease
or other permitted transfer relating to the Aircraft.

          (f) NO ASSIGNMENT. Lessee shall not assign, except in accordance with
this Section 8.01 or as otherwise expressly provided in this Lease, any interest
in this Lease or any of its rights hereunder or in any property leased
hereunder. Lessor shall have no responsibility for any increased costs resulting
from any assignment that is provided for under Section 8.01.

     Section 8.02 LAWFUL INSURED OPERATIONS. (a) Lessee will operate and use the
Aircraft only in or in connection with lawful
commercial passenger airline operations.

          (b) Lessee will not maintain the Aircraft, or permit the Aircraft to
be maintained in a manner contrary to the Maintenance Program or in violation of
any applicable Law or any certificate of airworthiness, permit, license or
registration issued by the Aeronautical Authority, except to the extent being
contested diligently and in good faith, and Lessee will not use or operate the
Aircraft, or permit the Aircraft to be used or operated in a manner contrary to
the Lessee's operating manuals approved by the Aeronautical Authority or
instructions or the Maintenance Program or in violation of any applicable Law or
in violation of any certificate of airworthiness, permit, license or
registration issued by the Aeronautical Authority, except to the extent being
contested diligently and in good faith, PROVIDED that in either case such
contest does not create any material risk of the loss or forfeiture of the
Aircraft or to cancellation, suspension or loss of insurance coverage.

          (c) [Intentionally Omitted]

          (d) Lessee will not operate the Aircraft, or permit the Aircraft to be
operated during the Term unless the Aircraft is covered by insurance as required
by the provisions hereof and such operation is in compliance with the terms of
such insurance.

          (e) Lessee solely shall bear any costs and expenses that may arise
from any loss or damage (with respect to both the Aircraft and any affected
third parties) that may occur during or in connection with operations of the
Aircraft including those that are excluded from coverage by the insurance
maintained in accordance with Article XI.

          (f) Lessee shall not at any time represent Lessor as carrying goods or
passengers in the Aircraft or as being in any way connected or associated with
the operation or carriage being undertaken by Lessee or as having any
operational interest in or responsibility for the Aircraft.

     Section 8.03 RESTRICTIONS ON OPERATION. Lessee shall not operate or locate
the Aircraft or permit the Aircraft to be operated or located on any routes or
in any country in any manner that (i) would be in breach of or violate any
relevant Law of the United States or in or over any area that may expose Lessor
or any Financing Party to any penalty, fine, sanction or other liability,
whether civil or criminal, under any applicable Law, or (ii), subject to Section
8.05, would result in the Aircraft being ineligible for registration in the name
of Lessor under 49 U.S.C. 44102(a)(1)(C). Lessee shall not operate the Aircraft
in any geographical area for which it is not duly authorized. Lessee shall not
use the Aircraft for training of

                                       29
<Page>

any Person other than its own employees and shall not use the Aircraft for
training its personnel more than it uses any other EMB-145 aircraft in its
fleet, whether owned or leased.

     Section 8.04 AOC. Lessee shall continue to hold an air carrier operator's
certificate with an operating specification allowing it to operate aircraft of
the same type as the Aircraft and for the purpose for which the Aircraft is
permitted to be used hereunder issued by the FAA.

     Section 8.05 REGISTRATION AND OPERATION. Except as otherwise permitted by
Section 5 of Exhibit A-2, or as otherwise required by the Federal Aviation Act
or rules, regulations, or orders promulgated thereunder, or to the extent that
such registration cannot be effected or continued due solely to the Lessor's
failure to comply with the citizenship or other eligibility requirements for
registration of commercial aircraft under the Federal Aviation Act or any rule,
regulation or order promulgated thereunder, Lessee shall at its expense keep the
Aircraft at all times registered under the applicable Laws of the United States
in the name of Lessor and, at all times that the Aircraft is being used and
operated for the public transport of passengers, shall insure that the Aircraft
possesses a valid, current certificate of airworthiness and such other
certificates, licenses, permits and authorizations as may be from time to time
required for the use and operation of the Aircraft for the public transport of
passengers; PROVIDED that the Lessor shall execute and deliver all such
documents as the Lessee may reasonably request for the purpose of effecting,
continuing or (as provided in this Section 8.05 of this Lease and Section 5 of
Exhibit A-2) changing such registration.

     Section 8.06 INSIGNIA. On the Delivery Date or promptly thereafter, but in
any event prior to the Aircraft being placed in service, Lessor shall place, and
at all times during the Term, Lessee shall maintain, in the cockpit of the
Airframe in a prominent location and on the gearbox of each Engine, a fireproof
plate of a reasonable size bearing the legend:

          "THIS AIRCRAFT/ENGINE IS OWNED BY WELLS FARGO BANK NORTHWEST, NATIONAL
     ASSOCIATION, NOT IN ITS INDIVIDUAL CAPACITY, BUT SOLELY AS OWNER TRUSTEE
     (THE "OWNER"), AND IS LEASED BY THE OWNER TO CHAUTAUQUA AIRLINES, INC."

Lessee agrees to make such changes to such identification plates as Lessor may
reasonably request from time to time.

     Section 8.07 REMOVED ENGINES. At any time when an Engine is installed on an
airframe or aircraft other than the Airframe or the Aircraft, Lessee shall
ensure that insurance cover is maintained incompliance with Article XI .
Notwithstanding anything herein to the contrary, Lessee shall not install, and
shall not permit the installation of, any Engine on any airframe that is not an
EMB-145 airframe or, if fully compatible in accordance with Manufacturer's and
Engine Manufacturer's specifications, an EMB-140 airframe.

     Section 8.08 MAINTENANCE. Lessee, at its own cost and expense, shall:

          (a) perform or cause a Maintenance Contractor to perform all service,
inspections, repairs, maintenance, modifications, alterations, overhaul, checks
(including heavy checks) and testing, (i) as may be required under the rules and
regulations of the Aeronautical Authority applicable to the Aircraft and in
compliance with the Maintenance Program and good commercial practice, (ii) as
may be included in any ADs, (iii) so as to keep the Aircraft airworthy (except
as otherwise provided in Section 8.08(b)) and in good operating order, repair,
condition and appearance and in at least as good operating condition and
appearance as when delivered to Lessee subject to normal wear and tear
associated with the operation and maintenance thereof in accordance herewith and
(iv) as required pursuant to Section 1(l) of EXHIBIT D-1 OR EXHIBIT D-2, AS
APPLICABLE. Lessee shall do each of the foregoing and shall incorporate Service

                                       30
<Page>

Bulletins, in the same manner and with the same care as is the case with similar
aircraft and engines of the same make and model as the Aircraft and Engines
owned by or operated by or on behalf of Lessee, without discrimination (as
compared to other similar aircraft owned or operated by Lessee) in contemplation
of the expiration or termination of this Lease with respect to the use,
operation or mandatory maintenance, other than the withdrawal of the Aircraft
from service as necessary to prepare the Aircraft for return to Lessor upon such
expiration or termination. Nothing in this Section 8.08(a) shall be construed in
such a manner as to require Lessee to modify the Aircraft in such a manner as to
reflect a configuration that is unique to Lessee solely because Lessee may be so
modifying other aircraft operated by it;

          (b) keep the Aircraft (i) in such condition as may be necessary to
enable the airworthiness certification of the Aircraft to be maintained in good
standing at all times (except during periods of maintenance, repair or
modification when the Aircraft is not operated, during any period when the
Aeronautical Authority shall have revoked or suspended the airworthiness
certification of all aircraft of the same type, model and series as the
Aircraft, and during any period which the Aircraft is in long-term storage) and
(ii) in compliance with Part 121 of the Federal Aviation Regulations (as set
forth in Title 14 of the U.S. Code of Federal Regulations), or, if the Aircraft
has been re-registered in accordance with the provisions of this Lease in a
country other than the United States, the requirements of the civil aviation
authority having jurisdiction over the Lessee's or any Permitted Sublessee's
operations, and all other applicable Law; and

          (c) maintain throughout the Term in a form that is accurate, complete,
and current all Aircraft Documents listed on EXHIBIT B and all log books, all
manuals and revisions and updates thereto, all certification and inspection
records (including without limitation all certifications and forms required by
the Aeronautical Authority and otherwise and all reports, x-rays, video tapes,
print-outs and other non destructive testing documents), and all other material
required by the Aeronautical Authority or required by the Maintenance Program
relating to operation, maintenance or other activity of the Aircraft during the
Term, with all such Aircraft Documents being in English.

     Section 8.09 COSTS. Lessee shall be responsible for and shall hold Lessor
harmless from all costs incurred in the operation of the Aircraft for profit or
otherwise, including, without limitation, the costs and expenses of flight
crews, cabin personnel, fuel, oil, lubricants, maintenance, insurance, landing
fees, navigation fees, airport charges and any and all other expenses or claims
of any kind or nature, directly or indirectly incurred or imposed in connection
with or related to the use, movement, operation, maintenance, repair, storage or
location of the Aircraft during the Term.

                                   ARTICLE IX

                       REPLACEMENT OF PARTS; MODIFICATIONS

     Section 9.01 REPLACEMENT AND REMOVAL OF PARTS. (a) Except as otherwise
provided in Section 9.01(f) or if the Airframe or an Engine to which a Part
relates has suffered an Event of Loss, Lessee, at its own cost and expense,
shall promptly replace or ensure the replacement of all Parts that, from time to
time, may become worn out, lost, stolen, destroyed, seized, confiscated, damaged
beyond repair or rendered unfit for use for any reason whatsoever.

          (b) In the ordinary course of maintenance, service, repair, overhaul
or testing during the Term, Lessee may at its own cost and expense cause to be
removed or allow the removal of any Parts, whether or not worn out, destroyed,
damaged beyond repair or rendered unfit for use, PROVIDED that Lessee shall

Part replaced

pursuant to Section 9.01(a) or (b), a "REPLACEMENT PART"), PROVIDED FURTHER,
HOWEVER, that Lessee may elect not to replace Parts only to the extent provided
in Section 9.01(f).

          (c) All Replacement Parts shall be free and clear of all Liens, shall
be Aeronautical Authority-approved and fully interchangeable, shall have been
overhauled, repaired and inspected by a Maintenance Contractor, except for
Permitted Liens and for pooling arrangements to the extent permitted by Section
9.03, and shall be in as good operating condition as, and have a utility at
least equal to and a value reasonably approximating, the Parts replaced
(assuming such Parts were in the condition and repair in which they were
required to be maintained by the terms hereof) and all serviceable tags or other
required documentation relating to the last overhaul of such Parts performed by
an Aeronautical Authority approved facility shall be provided and maintained by
Lessee.

          (d) All Parts owned by Lessor that are at any time removed from the
Aircraft shall remain the property of Lessor and subject to this Lease, no
matter where located, until such time as such Parts shall be replaced by parts
which have been incorporated or installed in or attached to the Aircraft and
that meet the requirements of Replacement Parts specified in Section 9.01(c) or
as otherwise provided in Section 9.01(f). Immediately upon any Replacement Part
becoming incorporated or installed in or attached to the Aircraft as above
provided, without further act, (i) title to the removed Part shall thereupon
vest in Lessee, free and clear of all rights of Lessor and any Financing Party
and Lessor's Liens, and such removed Part shall no longer be deemed a Part
hereunder, (ii) title to such Replacement Part shall thereupon vest solely in
Lessor, and (iii) such Replacement Part shall become subject to this Lease and
be deemed a Part for all purposes hereof to the same extent as the Part which it
has replaced.

          (e) Lessee shall be entitled, so long as no Event of Default shall be
continuing, to substitute, replace or renew any Part with a part that does not
satisfy the requirements of Section 9.01(c) PROVIDED that:

               (i) there shall not have been available to Lessee at the time and
     in the place that such substitute or replacement part was required to be
     installed on the Airframe or an Engine a substitute or replacement part
     complying with such requirements;

               (ii) it would have resulted in an unreasonable disruption of the
     operation of the Aircraft to have grounded the Aircraft until such time as
     a substitute or replacement part complying with such requirements became
     available for installation in or on the Aircraft; and

               (iii) as soon as practicable after installation of the same in or
     on the Airframe or Engine (which, in the case of an Engine, shall be no
     later than the next off-wing shop visit of the Engine) Lessee shall remove
     any such part not complying with such requirements and replace or
     substitute the same with a part complying with the same.

          (f) Lessee may, at its own cost and expense at any time during the
Term, remove or cause to be removed any Part from the Airframe or an Engine if
(i) such Part is in addition to, and not in replacement of or in substitution
for, any Part originally incorporated or installed in or attached to the
Airframe or such Engine at the time of delivery thereof hereunder or any Part in
replacement of, or in substitution for, any such original Part and (ii) such
Part can be removed from the Airframe or such Engine without materially (as
measured on an aggregate basis) diminishing or impairing the value, condition,
utility, airworthiness that the Airframe or such Engine would have had at the
time of removal had such removal not been effected by Lessee, assuming the
Aircraft was otherwise maintained in the condition required by this Lease,
PROVIDED that Lessee also may remove Parts that the Lessee deems obsolete or no
longer suitable or appropriate for use in the Aircraft, Airframe or such Engine
so long as the aggregate value of such removed Parts (based on their value as of
the Delivery Date) does not exceed

                                       32
<Page>

$200,000. Lessee shall only make such removals referred to in the proviso to the
first sentence of this Section 9.01(f) if such removals are made in the same
manner and with the same care as removals made in the case of similar aircraft
and engines of the same make and model as the Aircraft and Engines owned by or
operated by or on behalf of Lessee, without discrimination (as compared to other
similar aircraft owned or operated by Lessee). Upon the removal of any such
Part, title thereto shall vest, without further act, in Lessee free and clear of
all rights of Lessor and such Part shall no longer be deemed a Part hereunder.
Any Part not removed as above provided prior to the return of the Aircraft to
Lessor hereunder shall remain the property of Lessor.

          (g) Notwithstanding anything to the contrary contained in this Section
9.01, Lessee may not replace or remove any Parts in a manner that would prevent
it from complying with Section 1(b) of EXHIBIT D-1 or EXHIBIT D-2, as
applicable.

     Section 9.02 ALTERATIONS, MODIFICATIONS AND ADDITIONS. (a) Lessee, at its
own expense, shall promptly make or ensure or allow the making of such
alterations, modifications and additions to the Aircraft as may be required from
time to time to meet the applicable standards of the FAA or to comply with any
mandatory Law, rule, directive, bulletin, notice, regulation or order of any
Governmental Entity having jurisdiction over the Aircraft; PROVIDED that Lessee
may in good faith and by appropriate procedure, contest the validity or
application of any such standard in any reasonable manner which does not
materially and adversely affect the interests of the Lessor or Beneficiary and
does not involve any material risk of sale, forfeiture or loss of the Aircraft
or the interest of the Lessor or Beneficiary therein, any material risk of civil
penalty or any discernable risk of criminal liability being imposed on Lessor or
Beneficiary.

          (b) So long as no Specified Default has occurred and is continuing,
Lessee, at its own expense, may from time to time make other alterations,
modifications and additions to the Aircraft, subject to the following conditions
and limitations:

               (i)  Lessee may not make any such alteration, modification or
                    addition in a manner that would prevent it from complying
                    with Section 1(b) of EXHIBIT D-1 or EXHIBIT D-2, as
                    applicable;

               (ii) no such alteration, modification or addition diminishes the
                    remaining warranty status, value or utility, or impairs the
                    condition or airworthiness, of the Aircraft;

               (iii) title to all Parts incorporated or installed in or attached
                    or added to the Aircraft as a result of such alteration,
                    modification or shall vest immediately in Lessor and become
                    subject to this Lease, without the necessity for any further
                    act of transfer, document or notice

               (iv) Lessee shall only make such alterations, modifications and
                    additions in the same manner and with the same care as are
                    made in the case of similar aircraft of the same make and
                    model as the Aircraft owned by or operated by or on behalf
                    of Lessee, without discrimination (as compared to other
                    similar aircraft owned or operated by Lessee; PROVIDED that
                    Lessee shall be deemed to be in compliance with this Section
                    9.02(b)(iv) with respect to any alteration or modification
                    made to the Aircraft to meet the operational requirements of
                    any code share party under a code share or other similar
                    arrangement that is also made to other aircraft leased or

                                       33
<Page>

                    owned by Lessee that are subject to code sharing or similar
                    arrangements with such code share party; and

               (v)  No such alteration, modification or addition shall cause the
                    Aircraft to be limited use property, but without limiting
                    Lessee's right to remove Parts pursuant to Section 9.01(f).

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

     Section 9.03 POOLING OR PARTS LEASING. Any Part removed from the Airframe
or from any Engine as provided in Section 9.01 may be subjected by the Lessee to
a pooling or parts leasing agreement or arrangement that (i) is sponsored or
supervised by the Manufacturer or Engine Manufacturer or a manufacturer of such
Parts, (ii) is entered into in connection with a power by the hour agreement,
(iii) is based on immediate operational necessity or (iv) has been approved in
advance by the Lessor (such approval not to be unreasonably withheld), PROVIDED
that the part replacing such removed Part shall be incorporated or installed in
or attached to such Airframe or Engine in accordance with Section 9.01 as
promptly as practicable after the removal of such removed Part. In addition, any
Replacement Part when incorporated or installed in or attached to the Airframe
or any Engine in accordance with Section 9.01 may be owned by another airline or
vendor as customary in the airline industry, subject to any such pooling or
parts leasing arrangement, PROVIDED that the Lessee, at its expense as promptly
thereafter as reasonably practicable, either (x) causes title to such temporary
Replacement Part to vest in the Lessor in accordance with Section 9.01(d) by the
Lessee acquiring title thereto for the benefit of the Lessor free and clear of
all Liens except Permitted Liens, at which time such temporary replacement part
shall become a Part and become subject to this Lease or (y) replaces such
temporary Replacement Part by incorporating or installing in or attaching to
such Airframe or Engine a further Replacement Part owned by the Lessee free and
clear of all Liens except Permitted Liens and by causing title to such further
Replacement Part to vest in the Lessor in accordance with Section 9.01(d).

                            MANUFACTURERS' WARRANTIES

     Section 10.01 ASSIGNMENT. Lessor hereby assigns to Lessee all rights Lessor
has under any warranty, express or implied, with respect to the Aircraft and the
Engines or any Parts thereof made by the Manufacturer, the Engine Manufacturer,
or any other Person, and all proceeds thereof and recoveries thereunder under
the Manufacturer Purchase Agreement, Assignment No. 2, the Engine Warranty
Agreement and Engine Warranty Assignment and Consent and otherwise, to the
extent that such warranties exist or may be assigned or otherwise made available
to Lessee; PROVIDED, HOWEVER, that upon the occurrence of an Event of Default
and any termination of this Lease under Section 17.02 hereof, all such rights
shall, without further action or notice, immediately revert to Lessor including
all claims thereunder whether or not perfected. In the event any such warranties
are not assignable to Lessee, Lessor shall use commercially reasonable efforts
at Lessee's expense to enforce such warranties on Lessee's behalf so long as no
Event of Default shall have occurred and not been remedied or waived.

     Section 10.02 LIMITATIONS. Lessee shall not do or omit to do anything (or
permit or fail to prevent the doing or omission of anything) that, or the
omission of which, prejudices any right that Lessor or Lessee may have against
the Manufacturer, the Engine Manufacturer or against the manufacturer or
supplier of any part of the Aircraft or against any maintenance, conversion or
repair facility in respect of the Aircraft or any part thereof.

                                   ARTICLE XI

                                    INSURANCE

     Section 11.01 PUBLIC LIABILITY AND PROPERTY DAMAGE INSURANCE. Lessee shall,
without expense to the Lessor, maintain or cause to be maintained in effect at
all times during the Term, with an Approved Insurer, public liability insurance
(including, without limitation, aircraft third party, passenger legal liability,
property damage, general third party legal liability and product liability
coverage (in each case, without any exclusion for date recognition coverage) but
excluding manufacturer's product liability coverage) with respect to the
Aircraft in an amount not less than the greater of (x) the amount which Lessee
may carry from time to time on other similar aircraft in its fleet (whether
owned or leased) and (y) the Minimum Liability Amount; PROVIDED that an
agreement of a United States Entity backed by the full faith and credit of the
United States government for the benefit of the Additional Insureds to insure
against or indemnify for substantially the same risks to at least the same
amount shall satisfy the requirements of this Section 11.01, PROVIDED FURTHER,
that on or prior to the date of such agreement, the Lessee shall provide an
Officer's Certificate of the Lessee certifying that any such insurance or
indemnity provides protection no less favorable than insurance coverage that
would comply with this Section 11.01. Such insurance shall be of the type
usually carried by the Lessee with respect to similar aircraft and engines, and
covering risks of the kind customarily insured against by the Lessee and shall
be consistent with generally accepted industry-wide practice for airlines
similarly situated to Lessee with regard to the insurance of aircraft similar to
those operated by Lessee and based or operated in any jurisdiction in which the
Aircraft may then be based or operated.

     During any period of more than thirty (30) days that the Aircraft is placed
in short-term or long-term storage status, the Lessee may modify the insurance
required by this Section 11.01 to modify the amounts of public liability and
property damage insurance, the scope of the risks covered and the type of
insurance, in all circumstances to conform to such insurance customary in the
United States airlines industry for regional air carriers similarly situated
with the Lessee in respect of similar aircraft which are placed in short-term or
long-term storage status, except that in all instances the amounts of coverage
and scope of risk covered and the type of insurance shall be at a minimum no
less favorable than the insurance as from time to time applicable to aircraft
owned or leased by Lessee and in short-term or long-term storage status.

     Section 11.02 INSURANCE AGAINST LOSS OR DAMAGE TO THE AIRCRAFT AND ENGINES.
Subject to the rights of Lessee under Section 11.10, Lessee shall, without
expense to the Lessor, maintain or cause to be maintained in effect at all times
during the Term, with an Approved Insurer, all risk (which may, except as
provided in Section 11.04, exclude war and allied perils (but which shall not
contain any exclusion for date recognition coverage)), agreed value, ground and
flight hull insurance, covering the Aircraft for an amount at all times (even
when the Aircraft is grounded or in storage) not less than the Stipulated Loss
Value from time to time; PROVIDED that, the Lessee shall not be required to
maintain all-risk flight aircraft hull insurance with respect to any period in
which the Aircraft is placed in short term or long term storage status, and
PROVIDED FURTHER that all-risk flight aircraft hull insurance shall be in effect
during any check flights, ferry flights or other flight time during such
storage. Such insurance shall not provide insurers with a right to replace the
Airframe or any Engine with another airframe or Engine. Such hull insurance or
other personal property insurance of the Lessee shall cover Engines or engines
and Parts temporarily removed from the Airframe pending replacement by
installation of the same or similar Engines, engines or Parts on the Airframe in
an amount not less than the fair market value of such Engine or Part. Such
insurance shall be of the type usually carried by the Lessee with respect to
similar aircraft and engines, and covering risks of the kind customarily insured
against by the Lessee and shall be consistent with generally accepted
industry-wide practice for airlines similarly situated to Lessee with regard to
the insurance of aircraft similar to those operated by Lessee and based or
operated in any jurisdiction in

                                       35
<Page>

which the Aircraft may then be based or operated. An agreement of a United
States Entity backed by the full faith and credit of the United States
government to insure against or indemnify for substantially the same risks to at
least the same amount will satisfy any of the requirements of this Section
11.02.

     Section 11.03 ADDITIONAL INSUREDS; LOSS PAYMENT. The Lessee shall cause all
policies of insurance carried in accordance with this Article XI to name the
Additional Insureds as their respective interests may appear as additional
insureds and shall cause all policies required by Section 11.02 to name Lessor
as the sole loss payee. Such policies shall provide with respect to such
Additional Insureds that (a) none of their respective interests in such policies
shall be invalidated by any act or omission or breach of warranty or condition
contained in such policies by the Lessee or, in the case of any particular
Additional Insured, any other Additional Insured; (b) no cancellation or lapse
of coverage for nonpayment of premium or otherwise, and no substantial change of
coverage which adversely affects the interests of any such Additional Insured,
shall be effective as to such Additional Insured until 30 days (or 10 days in
respect of non-payment of premium and, in the case of war risk coverage, such
lesser period as may be applicable) after receipt by such Additional Insured of
written notice from the insurers of such cancellation, lapse or change; (c) they
shall have no liability for premiums, commissions, calls, assessments or
advances with respect to such policies; (d) such policies will be primary
without any right of contribution from any other insurance carried by such
Additional Insureds; (e) the insurers waive any rights of set-off, counterclaim,
deduction or subrogation against such Additional Insureds; (f) shall apply
worldwide and have no territorial restrictions or limitations (except, in the
case of war, hijacking or related perils insurance, as otherwise permitted
hereunder); and (g) shall contain a 50/50% Clause per Lloyd's Aviation
Underwriter's Association Standard Policy Form AVS 103 to the extent a separate
war risk policy is maintained. Each liability policy shall provide that all the
provisions thereof, except the limits of liability, shall operate in the same
manner as if there were a separate policy covering each insured and provide that
the exercise by the insurer of rights of subrogation derived from rights
retained by the Lessee will not delay payment of any claim that would otherwise
be payable but for such rights of subrogation. Each hull policy shall name the
Lessor as loss payee with respect to proceeds payable for an Event of Loss and
where the aggregate insurance proceeds exceed $750,000; PROVIDED that, so long
as the insurers shall not have received written notice that a Specified Default
has occurred and is continuing, if insurance proceeds in the aggregate equal to
$750,000 or less become payable, then such proceeds shall be payable to the
Lessee and, notwithstanding the foregoing, any amounts up to Stipulated Loss
Value (x) of any proceeds which in the aggregate exceed $750,000, (y) of any
proceeds in respect of an Event of Loss or (z) if the insurers shall have
received written notice that a Specified Default has occurred and is continuing,
any proceeds with respect to any single loss, shall be payable to Lessor as loss
payee.

     Section 11.04 WAR RISK. Subject to the rights of Lessee under Section
11.10, if and to the extent that the Lessee or a Permitted Sublessee operates
the Aircraft (a) on routes for which it maintains war risk, hijacking or allied
perils insurance in effect with respect to other similar owned or leased
aircraft in its fleet, (b) on routes (other than routes within the United States
and Canada) where the custom in the industry is to carry war risk insurance, or
(c) in any area of recognized hostilities, the Lessee or such Permitted
Sublessee shall maintain or cause to be maintained a war risks insurance policy
(hull and liability) on the Aircraft covering all of those risks that are
currently enumerated in Lloyds Form AVN 48B (War, Hijacking and Other Perils
Exclusion Paragraph (Aviation)) to the fullest extent possible and any
additional risks that may hereafter be included therein or in any form
succeeding to any of its functions in an amount with respect to hull, not less
than the Stipulated Loss Value and, with respect to liability, in an amount not
less than the Minimum Liability Amount. An agreement of a United States Entity
backed by the full faith and credit of the United States government to insure
against or indemnify for substantially the same risks to at least the same
amount will satisfy any of the requirements of this Section 11.04.

     Section 11.05 APPLICATION OF HULL INSURANCE PROCEEDS. As between the Lessor
and the Lessee, any payments received under policies of hull or other property
insurance required to be maintained by the Lessee pursuant to Section 11.02 or
11.04, shall be applied as follows:

          (a) if such payments are received 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 the Airframe, payments in the aggregate of $750,000 or
less shall be paid over to or retained by the Lessee and, subject to Section
11.03, any payments which in the aggregate are greater than $750,000 shall be
paid over to or retained by the Lessor for payment to the Lessee only upon
performance of its repair or replacement obligation as set forth in Section
12.02;

          (b) if such payments are received with respect to an Event of Loss
with respect to the Airframe, or the Airframe and Engines or engines installed
thereon, and the Airframe is not being replaced by the Lessee pursuant to
Section 12.01(a)(ii) or has not been replaced by Lessee pursuant to Section
12(a)(ii) within one hundred twenty (120) days after the Event of Loss, so much
of such payments as shall not exceed the amounts required to be paid by the
Lessee pursuant to Section 12.01(a)(i) shall be applied in reduction of the
Lessee's obligation to pay such amounts if not already paid by the Lessee and to
reimburse the Lessee if such amounts shall have been paid, and the balance, if
any, of such payments shall be promptly paid over to or retained by the Lessee;

          (c) if such payments are received with respect to the Airframe or the
Airframe and Engines or engines installed thereon as a result of an Event of
Loss with respect thereto and the Airframe is being replaced by the Lessee
pursuant to Section 12.01(a)(ii), such payments shall be paid over to, or
retained by the Lessee, PROVIDED that if the Lessee has not completed such
replacement and the performance of all other obligations under Section 12.01(c),
such payments shall be paid over to, or retained by, the Lessor as security, and
upon completion of, or in connection with a closing for, such replacement, be
paid over to or retained by the Lessee or, if such completion of a replacement
has not occurred within the applicable time period, applied as provided in
Section 11.05(b).

     Section 11.06 INSURANCE BY LESSOR. Nothing in this Article XI shall
prohibit the Lessee, the Lessor, or any other Additional Insured from obtaining
insurance with respect to the Aircraft, any Engines or engines installed on the
Airframe, or any Part for its own account (including, without limitation, in the
case of the Lessee, hull insurance under the same policies maintained pursuant
to this Article XI in amounts in excess of those required to be maintained
pursuant to this Article XI) and any proceeds payable thereunder shall be
payable as provided in the insurance policy relating thereto, PROVIDED that no
such insurance may be obtained which would limit or otherwise adversely affect
the availability of coverage or payment of any insurance required to be obtained
or maintained pursuant to this Article XI, it being understood that all salvage
rights to the Airframe or the Engines shall remain with the Lessee's insurers at
all times.

     Section 11.07 REPORTS, ETC. (a) Lessee will furnish to the Lessor (i) on or
prior to the Delivery Date, insurance certificates describing in reasonable
detail the insurance maintained by Lessee as required pursuant to this Article
XI, (ii) prior to the cancellation, lapse or expiration of the insurance
policies required pursuant to this Article XI, evidence of renewal of such
insurance policies, and (iii) on or prior to the Delivery Date and on or before
the renewal dates of the insurance policies carried by the Lessee pursuant to
this Article XI, a report signed by a firm of aircraft insurance brokers, not
affiliated with the Lessee, appointed by the Lessee and reasonably satisfactory
to the Lessor, stating the opinion of such firm that all premiums in connection
with the insurance then due have been paid and the insurance then carried and
maintained on the Aircraft complies with the terms hereof and, in the case of
renewal insurance, that such renewal insurance will on and after the effective
date thereof so comply with the terms hereof, PROVIDED that all information
contained in such report shall be held confidential by the Lessor and

                                       37
<Page>

Beneficiary and shall not be furnished or disclosed by them to anyone except
their legal counsel, insurance brokers or advisors, bona fide prospective
transferees of the Lessor and Beneficiary and their respective agents (PROVIDED
that they shall agree for the benefit of the Lessee to hold all such information
similarly confidential) or as may be required by applicable Law. The Lessee will
instruct such firm to give prompt written advice to the Lessor of any default in
the payment of any premium and of any other act or omission on the part of the
Lessee of which it has knowledge and which would in such firm's opinion
invalidate or render unenforceable, in whole or in any material part, any
insurance on the Aircraft. The Lessee will also instruct such firm to advise the
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 this Article XI (or such lesser period as may be applicable
in the case of war risk coverage).

          (b) Lessee shall use reasonable efforts to notify Lessor promptly of
any event (other than an event constituting an Event of Loss, notice of which
shall be governed by Section 12.01(a) or (b), as applicable) with respect to the
Aircraft, the Airframe, any Engine or any Part thereof that will or may give
rise to a claim under any hull risk insurance policy in excess of $750,000,
PROVIDED that receipt by Lessor of any payments pursuant to Section 11.05(a)
shall be deemed to constitute notice of such event, subject to Lessee providing
such additional information regarding such event as Lessor shall request after
receipt of such payment.

          (c) If at any time and from time to time, Lessor shall identify a
Financing Party to Lessee, Lessee shall cause to be delivered new insurance
certificates and broker's undertakings to ensure that each such Financing Party
is afforded the insurance coverage required under this Lease.

     Section 11.08 NEGATIVE UNDERTAKINGS. (a) Lessee shall not knowingly do or
omit to do or permit to be done or left undone anything whereby any policy
required to be maintained under this Article XI would or may reasonably be
expected to be rendered in whole or in part invalid or unenforceable.

          (b) Without prejudice to the obligations of Lessee under Section
11.08(a), Lessee shall not operate or locate the Airframe or any Engine or
suffer the Airframe or any Engine to be operated or located, (i) in any area or
for carriage of any goods excluded from coverage by any insurance required by
the terms of this Article XI, except in the case of requisition by or any
contract with any Governmental Entity where Lessee obtains an indemnity in lieu
of such insurance from such Governmental Entity against the risks and in the
amounts required by this Article XI in respect of such area or such carriage of
any goods, or (ii) in any recognized or threatened area of hostilities unless
fully covered by war risk insurance or unless the Airframe or Engine is operated
or used under contract with any Governmental Entity under which contract such
Governmental Entity assumes full liability for any damage, loss, destruction or
failure to return possession of such Airframe or Engines at the end of the term
of such contract and for injury to persons and damage to property of others, or
(iii) in any place or in any manner or for any purpose inconsistent with the
terms or outside the cover provided by any such policy, and the result of such
operation or location is that any policy required to be maintained under this
Article XI would or may be reasonably expected to be rendered in whole or in
part invalid or unenforceable, PROVIDED that if Lessee unintentionally and
temporarily operates or locates the Airframe or any Engine or suffers the
Airframe or any Engine to be operated or located in violation of this Section
11.08(b ), Lessee shall be deemed not to have breached its obligations under
this Section 11.08(b ) if, upon a Responsible Officer becoming aware thereof,
Lessee promptly terminates any such operation or changes such location that
resulted in such violation and takes reasonable affirmative actions to prevent
the operation or location of the Aircraft in violation of Section 11.08(b)
occurring again.

     Section 11.09 FAILURE TO INSURE.  If Lessee shall fail to maintain or cause
there  to be  maintained  insurance  as  herein  provided,  Lessor  may,  at its
option,provide such insurance and in such event Lessee

                                       38

shall, upon demand, reimburse  Lessor for the cost thereof.  Such provision by
Lessor  shall not affect the right of Lessor to treat such  failure by Lessee as
an Event of Default.

     Section 11.10 DEDUCTIBLE. For insurance provided pursuant to Section 11.02
or 11.04, a deductible per occurrence that is not in excess of the prevailing
standard market deductible for similar aircraft shall be permitted for each
aircraft in the Lessee's fleet. In no case shall the amount of the deductible
during any policy year with respect to the Aircraft exceed $750,000 unless
Lessee provides a report from the Lessee's independent insurance broker
confirming that any higher deductible amount maintained by Lessee does not
exceed the amount maintained by airlines similarly situated to Lessee with
regard to the insurance of aircraft similar to those operated by Lessee and
based or operated in any jurisdiction in which the Aircraft may then be based or
operated.

                                  EVENT OF LOSS

     Section 12.01 EVENT OF LOSS WITH RESPECT TO THE AIRFRAME. (a) Upon the
occurrence of an Event of Loss to the Airframe or the Airframe and the Engines
or engines then installed on the Airframe, Lessee (x) shall as soon as possible
(and, in any event, within five (5) days after the occurrence of such Event of
Loss) provide written notice to Lessor and Beneficiary of such Event of Loss and
(y) shall forthwith (and, in any event, within sixty (60) days after the
occurrence of such Event of Loss), give written notice to Lessor of its election
to perform one of the following options (it being understood that, if Lessee
fails to give such notice, or if Lessee has elected the option set forth in
clause (ii) below but has failed to comply with the provisions thereof or with
the provisions of Section 12.01(c), Lessee shall be deemed to have elected the
option set forth in clause (i) below):

               (i) On or before the date that is ninety (90) days after the date
     of any Event of Loss with respect to the Airframe or the Airframe and any
     Engines or engines, but in no event later than two (2) Business Days after
     receipt of insurance or other proceeds in respect of such Event of Loss
     (or, if Lessee has elected to replace the Airframe or the Airframe and any
     Engines or engines pursuant to Section 12.01(a)(ii), on the first Business
     Day after the 120th day following the Event of Loss), Lessee shall pay to
     Lessor the sum of (A) the Stipulated Loss Value PLUS (B) the amount of
     Basic Rent, if any, due and unpaid on such date, PLUS (C) the amount of
     deferred Basic Rent, if any, as of such date as set forth in the column
     headed "Deferred Basic Rent" in Schedule SLV, MINUS (D) the amount of
     prepaid Basic Rent, if any, as of such date as set forth in the column
     headed "Prepaid Basic Rent" in Schedule SLV, PLUS (E) all Supplemental Rent
     (other than Stipulated Loss Value) unpaid as of such date; or

               (ii) So long as (A) no Specified Default has occurred and is
     continuing, and (B) the conditions set forth in Section 12.01(c) are met,
     Lessee may substitute another Embraer aircraft model EMB-145LR or Embraer
     airframe model EMB-145LR of the same or later vintage as the Airframe that
     suffered the Event of Loss together with one or more Rolls-Royce Allison AE
     300 7A1P engines, as the case may be, or an improved model of the Airframe
     and Engines, if any, that suffered the Event of Loss, that, in each case,
     has a value, utility, condition, maximum take-off weight, maximum landing
     weight (and in the case of an engine, with an equal or greater engine
     thrust rating), estimated residual value and remaining useful life equal to
     or greater than, and in as good an operating condition as, the Airframe and
     Engines, if any, that suffered such Event of Loss (assuming that such
     Airframe and Engines were then in the condition required by the terms of
     this Lease) within 120 days following the occurrence of such Event of Loss
     in accordance with the terms and provisions of Section 12.01(c) below.

                                       39
<Page>

          (b) If an Event of Loss occurs with respect to the Airframe and Lessee
elects the option set forth in clause (i) of Section 12.01(a), then upon payment
in full by Lessee of all amounts referred to therein:

               (i) the obligations of the Lessee to pay Rent (except for
     Supplemental Rent obligations surviving pursuant to Section 6.05 and
     Articles XIV and XV of this Lease or the Tax Indemnity Agreement or which
     have otherwise accrued but not been paid as of the Termination Date) shall
     cease;

               (ii) the Term shall end; and

               (iii) Lessor will transfer to Lessee, without recourse or
     warranty (except as set forth below) on an as-is, where-is basis, all of
     Lessor's right, title and interest, if any, in and to the Airframe and
     Engines (if any) suffering the Event of Loss, as well as all of Lessor's
     right, title and interest in and to any Engine constituting part of the
     Aircraft but not installed thereon at the time of the Event of Loss, by way
     of a bill of sale conveying to Lessee such title as was received by Lessor
     on the Delivery Date, free of Lessor's Liens, but subject to Liens arising
     by or through Lessee.

     Nothing in this Section 12.01(b) shall be deemed to relieve Lessee of its
obligation to pay Rent prior to the date on which the Stipulated Loss Value and
all other amounts due hereunder have been paid in full.

          (c) If an Event of Loss occurs with respect to the Airframe and Lessee
elects the option set forth in clause (ii) of Section 12.01(a), then Lessee
shall duly convey to Lessor, at its sole cost and expense, and shall reimburse
Lessor for any out-of-pocket costs and expenses incurred in connection
therewith, as replacement for the Aircraft that suffered the Event of Loss,
title to a Replacement Aircraft (or a Replacement Airframe or a Replacement
Airframe and a Replacement Engine which, together with the Engine or Engines
constituting a part of the Aircraft but not installed thereon at the time of the
Event of Loss, constitute the Aircraft) free and clear of all Liens except
Permitted Liens described in clauses (i), (ii) and (iii) of the definition
thereof. Prior to or at the time of such conveyance, Lessee shall at its
expense:

               (i) furnish to Lessor a full warranty bill of sale, in form and
     substance reasonably satisfactory to Lessor, with respect to such
     Replacement Aircraft or Replacement Airframe and Replacement Engines, if
     any,

               (ii) cause a supplement hereto, in form and substance reasonably
     satisfactory to Lessor, subjecting such Replacement Aircraft or Replacement
     Airframe and Replacement Engines to the terms of this Lease, to be duly
     executed by Lessee and recorded as may be necessary or as Lessor may
     request pursuant to the Federal Aviation Act,

               (iii) cause Uniform Commercial Code financing statement(s) to be
     filed in such place or places as may be necessary or advisable in order to
     evidence and perfect the interests of Lessor in and to such Replacement
     Aircraft or Replacement Airframe and Replacement Engines under applicable
     law,

               (iv) furnish Lessor with such evidence as to Lessee's title to
     such Replacement Aircraft or Replacement Airframe and Replacement Engine
     and as to the integration of substituted property into the Maintenance
     Program as Lessor may reasonably request,

                                       40
<Page>

               (v) furnish Lessor with a certificate of an authorized officer of
     Lessee together with an appraisal by a qualified independent appraiser of
     nationally recognized standing reasonably acceptable to Lessor that such
     Replacement Aircraft or Replacement Airframe and Replacement Engines have a
     value, utility, condition, maximum take-off weight, maximum landing weight
     (and in the case of an engine, with an equal or greater engine thrust
     rating) and remaining useful life, at least equal to, and are in as good an
     operating condition as, the Aircraft, or the Airframe and Engines, if any,
     subject to the Event of Loss (assuming that such Aircraft, or Airframe and
     Engines were in the condition required by the terms of this Lease),
     together with an insurance certificate related thereto evidencing
     compliance with Article XI,

               (vi) furnish Lessor with an opinion of counsel, reasonably
     acceptable to Lessor, to the effect that title to such Replacement Aircraft
     or Replacement Airframe and Replacement Engines have been duly conveyed to
     Lessor free and clear of all Liens except Permitted Liens and that such
     Replacement Aircraft is duly leased hereunder, and that the supplement to
     this Lease covering the same has been duly recorded under applicable Law
     together with a favorable opinion of counsel, acceptable to Lessor in its
     reasonable discretion, as to the availability of Section 1110 of the
     Bankruptcy Code or any successor statute thereto having similar subject
     matter to Section 1110 with respect to such Replacement Aircraft or
     Replacement Airframe and Replacement Engines and as to such other matters
     as may be reasonably requested by Lessor or Beneficiary,

               (vii) furnish Lessor with an opinion (in form and substance
     reasonably acceptable to Lessor) of independent tax counsel selected by
     Lessee and reasonably acceptable to Lessor, to the effect that the
     replacement of the Aircraft or the Airframe and Engine, as applicable, will
     not cause any adverse tax consequences to Lessor or, in lieu of such
     opinion, furnish Lessor with an indemnity satisfactory to Lessor against
     any such adverse tax consequences,

               (viii) provide all other documentation and take such other action
     as may be necessary or as Lessor may reasonably request in order that such
     Replacement Aircraft or Replacement Airframe and Replacement Engines be
     duly and properly titled in Lessor and covered by the insurance policies
     required under Article XI,

               (ix) cause such Replacement Aircraft to be duly registered in
     Lessor's name at the FAA, and

               (x) subject to Section 10.01, assign to Lessor the benefit of all
     assignable manufacturers' warranties with respect to such Aircraft or
     Replacement Airframe and Replacement Engines.

     Upon full compliance by Lessee with the terms of this Section 12.01(c),
Lessor will transfer to Lessee without recourse or warranty (except as set forth
below) on an as-is, where-is basis, all of Lessor's right, title and interest,
if any, in and to the Airframe and Engines (if any) suffering the Event of Loss,
by way of a bill of sale conveying to Lessee such title as was received by
Lessor on the Delivery Date, free of Lessor's Liens, but subject to Liens
arising by or through Lessee, and shall remit to Lessee any insurance proceeds
relating to property damage from policies maintained by Lessee or any Permitted
Sublessee pursuant to Article XI or net condemnation award, in either case,
actually received by Lessor. For the avoidance of doubt, Lessee agrees that it
shall be solely responsible for the location of any Replacement Aircraft,
Replacement Airframe or Replacement Engine at the time that it is to be so
transferred in relation to any liability of Lessee under Article XIV. For all
purposes hereof, the property so substituted shall be deemed an "AIRCRAFT,"
"AIRFRAME" and "ENGINE," as the case may be, as defined herein. No Event of Loss
with respect to the Aircraft or the Airframe and the Engines or engines then

                                       41
<Page>

installed thereon for which substitution has been elected pursuant to this
Section 12.01(c) shall result in any reduction in any sum due from Lessee under
any Operative Document.

         Section 12.02 SUBSTITUTION OF ENGINES. (a) Upon an Event of Loss with
respect to an Engine under circumstances in which there has not occurred an
Event of Loss with respect to the Airframe, Lessee (x) shall as soon as possible
(and, in any event, within ten (10) Business Days after the occurrence of such
Event of Loss) provide written notice to Lessor and Beneficiary of such Event of
Loss and (y) shall as soon as possible (and, in any event, within ninety (90)
days after the occurrence of such Event of Loss) convey to Lessor, as
replacement for the Engine suffering such Event of Loss, title to a Replacement
Engine in accordance with this Section 12.02(a), free of all Liens (except Liens
permitted by clauses (i ), (ii ), (iii ) and (v ) of the definition of Permitted
Liens). Prior to or at the time of any such transfer, Lessee, at its own
expense, will promptly

               (i) furnish Lessor with a full warranty bill of sale (excluding
     Liens permitted by clauses (i), (ii), (iii) and (v) of the definition of
     Permitted Liens) of that is, by its terms, governed by the laws of the
     State of New York and otherwise in form and substance reasonably
     satisfactory to Lessor with respect to such Replacement Engine;

               (ii) execute and deliver a supplement hereto, in form and
     substance reasonably satisfactory to Lessor, subjecting such Replacement
     Engine to this Lease;

               (iii) furnish Lessor with such evidence of title to such
     Replacement Engine and of compliance with the insurance provisions of
     Article XI with respect to such Replacement Engine as Lessor may reasonably
     request; and

               (iv) furnish Lessor with such documents as Lessor may reasonably
     request in connection with the completion of the transactions contemplated
     by this Section 12.02, in each case in form and substance reasonably
     satisfactory to Lessor.

     Upon full compliance by Lessee with the terms of this Section 12.02, Lessor
will transfer to Lessee "AS IS, WHERE IS" and without recourse or warranty,
except a warranty as to the absence of Liens arising by or through Lessor, such
right, title and interest in the Engine that suffered the Event of Loss as
Lessor received on the Delivery Date. For all purposes hereof, each such
Replacement Engine shall be deemed part of the property leased hereunder, shall
be deemed an "Engine" as defined herein. No Event of Loss covered by this
Section 12.02 shall result in any reduction in Rent.

          (b) In connection with the return of the Aircraft pursuant to Section
18.03 or at any time during the Term, so long as no Specified Default shall have
occurred and be continuing, on at least thirty (30) days prior written notice to
Lessor, the Lessee may elect to replace an Engine on the Airframe with a
Replacement Engine in accordance with this Section 12.02. In such event, Lessee
shall convey to Lessor, as replacement for the Engine suffering such deemed
Event of Loss, title to a Replacement Engine in accordance with the provisions
of Section 12.02(a).

     Section 12.03 APPLICATION OF PROCEEDS AND PAYMENTS. Any payments received
at any time by Lessor or by Lessee from any insurer under any policy of
insurance required to be maintained pursuant to Article XI (other than liability
insurance) shall be applied in the manner specified in Section 11.05. Subject to
Section 4.07, any payments received at any time by Lessor or Lessee from any
Governmental Entity or other Person (except as provided in the preceding
sentence) with respect to an Event of Loss will be applied as follows:

          (a) if such payments are received as a result of an Event of Loss with
respect to the Airframe (or the Airframe and the Engine or Engines installed
thereon):

               (i) so much of such payments as shall not exceed the amounts
     payable by Lessee pursuant to Section 12.01(a)(i) shall be paid to Lessor
     in reduction of Lessee's obligation to pay such amounts if not already paid
     by Lessee, or, if already paid by Lessee, shall be applied by Lessor to
     reimburse Lessee for its payment of such amounts and the balance of such
     payment, if any, remaining thereafter shall be paid over to, or retained
     by, Lessee; or

               (ii) if the Airframe (or the Airframe and the Engines or Engines
     installed thereon) is being replaced in accordance with Section
     12.01(a)(ii), all such payments shall be held by Lessor as security until
     such time as Lessee shall have fully complied with its obligations under
     Section 12.01(a)(ii) and (c), whereupon such payments shall be paid over to
     Lessee or to such other Person or Persons as Lessee may direct or shall be
     applied as provided in Section 12.01(a)(i) if such replacement is not
     completed within the applicable time period; and

          (b) if such payments are received with respect to an Event of Loss to
an Engine that has been or is being replaced by the Lessee pursuant to the terms
hereof, such payments shall be paid over to, or retained by, the Lessee,
PROVIDED that if the Lessee has not completed such replacement, such payments
shall be paid over to, or retained by, the Lessor as security, and upon
completion of, or in connection with a closing for, such replacement in
accordance with Section 12.02, shall be paid over to or retained by the Lessee.

     Section 12.04 REQUISITION FOR USE BY GOVERNMENT. In the event of the
requisition for use by a Governmental Entity of the Airframe or any Engine
(other than a requisition constituting an Event of Loss), all Lessee's
obligations under this Lease shall continue to the same extent as if such
requisition had not occurred, except to the extent that performance or
observance of any obligation by the Lessee shall have been prevented or delayed
as a result of such requisition (other than Lessee's obligations to pay Rent and
its obligation under Article XI hereof). If the Airframe or any Engine or engine
installed thereon is not returned by such Governmental Entity prior to the last
day of the Term, the Term shall nonetheless terminate on such last day. Subject
to Section 4.07, all payments received by Lessor or Lessee from the Governmental
Entity for the use of the Airframe or Engine during the Term prior to the time
such requisition becomes an Event of Loss shall be paid over to, or retained by,
Lessee; PROVIDED that any such payments received by Lessor may be offset against
Lessee's obligation to pay Rent; and all payments received by Lessor or Lessee
from the Governmental Entity for the use of such item after such requisition
constitutes an Event of Loss or after the expiration of the Term and the receipt
by Lessor of payment of Stipulated Loss Value, shall be paid over to, or
retained by, Lessee. Lessee shall, as soon as practicable after the termination
of any requisition for use or hire, cause the Aircraft to be put into the
condition required by this Lease.

effect upon Lessee or upon its ability to perform its obligations hereunder;

          (c) upon request of Lessor, (i) notice of scheduled maintenance on the
Aircraft equivalent to a C check or greater and the locations thereof, together
with reasonable prior written notice of any changes in the schedule so provided,

review has not disclosed the existence during such period, nor does the signer
have knowledge of the existence as of the date of such certificate, of any
condition or event which constituted or constitutes a Default or Event of
Default, or, if any such condition or event existed or exists, specifying the
nature and period of existence thereof and what action the Lessee has taken or
is taking or proposes to take with respect thereof.

     Section 13.02 INSPECTION RIGHTS. (a) Once in each twelve month period
during the Term on reasonable notice, and at any time so long as an Event of
Default is continuing and with one (1) Business Day's notice or such shorter

any Financing Party and/or their respective authorized representatives (it being
understood that Lessor, during the twelve (12) month period immediately
preceding the last day of the Term, may designate the Manufacturer as its

shall assist Lessor, but shall not be responsible to obtain airport security
clearance) and workplace rules applicable at the location where such inspection
is conducted and any applicable governmental rules or regulations, and (ii) so
long as Lessor is not exercising its remedies under Section 17.02, in the case
of an inspection during a maintenance visit, such inspection shall not in any
respect interfere with the normal conduct of such maintenance visit or extend
the time required for such maintenance visit or interfere with the use or
operation of the Airframe or any Engine or with the normal conduct of Lessee's
business.

          (b) Lessor shall have no duty to make any such inspection and shall
not incur any liability or obligation by reason of not making any such

remain vested in Lessor and it is the intent of Lessor and Lessee that this
Agreement shall constitute a lease for all purposes and shall not be

and expense at the reasonable request of Lessor, cause this Lease and any
financing statements with respect thereto, and any and all additional

operation of law or pursuant to or in compliance with any judgment, decree or
order of any court or of any other Governmental Entity):

          (a) Lessee shall fail to make any payment of Rent to Lessor when due
and in the manner and at the place required under this Lease and such failure

          (e) Lessee shall make or permit any assignment or transfer of this
Lease, or any interest therein, or of the right to possession of or operational

          (f) Lessee shall fail to perform or observe any other material
covenant, condition or agreement to be performed or observed by it pursuant to
this Lease or any other Operative Document to which it is a party (other than

period of thirty (30) days after delivery of notice of such failure from the
Lessor to the Lessee, unless such failure is curable and the Lessee shall, after
the delivery of such notice (or such date), be diligently proceeding to correct
such failure and shall in fact correct such failure within 120 days after
delivery of such notice (or such date), PROVIDED that the covenant to provide
notice to Lessor in Section 13.01(b) shall be deemed to be cured if Lessee
provides such notice within the foregoing time periods after notice from Lessor,
unless Lessor shall have been materially adversely affected by the delay in the
delivery of such notice;

composition, extension or adjustment with its creditors;

          (h) An order, judgment or decree is entered by any court, with or
without the consent of Lessee appointing a receiver, examiner, administrator,
trustee, official manager, custodian or liquidator or provisional liquidator for
Lessee or if all or any substantial part of the property of Lessee is
sequestered, and any such order, judgment or decree of appointment or
sequestration remains in effect, undismissed, unstayed or unvacated for a period
of sixty (60) days after the date of entry thereof;

          (i) A petition against Lessee in a proceeding under the bankruptcy,
insolvency or other similar Laws (as now or hereafter in effect) is filed and is
not withdrawn or dismissed within sixty (60) days thereafter and is not being

and is not being disputed in good faith with reasonable chance of success;

          (j) Lessee voluntarily or involuntarily suspends all or substantially
all of its operations or if all or substantially all of the franchises,
concessions, permits, licenses, rights or privileges required for the conduct of
the business and operations of Lessee are revoked, canceled or otherwise
terminated and, in the case of any involuntary suspension only, such involuntary

from a general grounding by the Aeronautical Authority of all aircraft of the
same type and series as the Aircraft, such involuntary suspension continues for
a period of one hundred eighty (180) days;

          (k) This Lease ceases to be in full force and effect or to be a legal,

or omission of Lessee;

          (l) Lessee repudiates its obligations under this Lease in whole or in
material part;

          (m) An "Event of Default" shall have occurred under any Other Lease
(as defined therein);

          (n) Lessee shall cease at any time during the Term to be a Section

          (o) Lessee shall receive notice of default or exercise of remedies
with respect to the payment or performance of any indebtedness or other
obligation to any third party and any such default or exercise of remedies
results in an acceleration of such indebtedness or obligation; provided,
however, that the aggregate amount of any such indebtedness or obligation is in
excess of $3,500,000 (determined in the case of borrowed money by the amount
outstanding under the agreement pursuant to which such borrowed money was
borrowed, in the case of a deferred purchase price by the remaining balance and

thereunder);

                                       47
<Page>

PROVIDED that, notwithstanding anything to the contrary contained in this Lease,
any failure of the Lessee to perform or observe any covenant, condition, or
agreement herein shall not constitute an Event of Default under clause (f) above
if such failure is caused solely by reason of an event referred to in the
definition of "EVENT OF LOSS" so long as the Lessee is continuing to comply with
the applicable terms of Section 12.

     Section 17.02 REMEDIES. (a) Upon the occurrence of any Event of Default,
Lessor may at its option declare this Lease to be in default; PROVIDED that,
upon the occurrence of any Event of Default specified in paragraphs (g), (h) or
(i) of Section 17.01, this Lease shall automatically be deemed to have been
declared in default. Once this Lease has been declared to be in default or is
deemed to have been so declared then, and at any time thereafter, Lessor shall
be entitled to exercise any of the following remedies as Lessor in its sole
discretion shall elect, to the extent permitted by applicable Law then in effect
without making demand or giving notice or the taking of any other action,
require that Lessee, and Lessee shall upon the written request of Lessor and at
Lessee's expense, immediately return the Aircraft to Lessor in the manner
specified in such written request, in which event such return shall not be
delayed for purposes of complying with the return conditions specified in
Article XVIII (none of which conditions shall be deemed to affect Lessor's
possession of the Aircraft) or be delayed for any other reason, PROVIDED
HOWEVER, that Lessor, at Lessor's option, may require Lessee to and Lessee shall
thereafter take such actions as would be required by the provisions of this
Lease if the Aircraft were being returned at the end of the Term, subject to
making the Aircraft available to Lessee if Lessor has then repossessed the
Aircraft. In addition, Lessor, at its option and to the extent permitted by
applicable Law, may enter upon the premises where all or any part of the
Aircraft is located and take immediate possession of and, at Lessor's sole
option, remove the same (including any engine that is not an Engine but that is
installed on the Airframe, subject to the rights of the owner, lessor or secured
party thereof) by summary proceedings or otherwise;

          (b) Sell at private or public sale, as Lessor may determine, or hold,
use, operate or lease to others the Aircraft as Lessor in its sole discretion
may determine, all free and clear of any rights of Lessee except as set forth in
this Section 17.02;

          (c) Whether or not Lessor shall have exercised, or shall thereafter at
any time exercise, any of its rights under paragraph (a) or (b) above, Lessor,
by fifteen (15) days' written notice to Lessee specifying a payment date, may
demand that Lessee pay to Lessor, and Lessee shall pay to Lessor, on the payment
date specified in such notice any unpaid Basic Rent for the Aircraft to and
including the payment date specified in such notice, PLUS, as liquidated damages
for loss of bargain and not as a penalty (in lieu of Basic Rent payable for the
period commencing after the date specified for payment in such notice),
whichever of the following amounts Lessor, in its sole discretion, shall specify
in such notice (together with accrued interest thereon, if any, to the extent
permitted by applicable Law at the Interest Rate from the date specified for
payment in such notice to the date of actual payment: (i) the amount if any, by
which (x) the Stipulated Loss Value computed as of the payment date specified in
such notice (plus the amount of the deferred Basic Rent, if any, as of such date
as set forth in the column headed "Deferred Basic Rent" in Schedule SLV, and
minus the amount of prepaid Basic Rent, if any, as of such date as set forth in
the column headed "Prepaid Basic Rent" in Schedule SLV), exceeds (y) the
aggregate Fair Market Rental Value (determined in accordance with the Appraisal
Procedure) of the Aircraft for the remainder of the Basic Term (or if in a
Renewal Term, then until the scheduled end of the Renewal Term), after
discounting such Fair Market Rental Value periodically (equal to installment
frequency) to present worth as of the payment date specified in such notice
using the Treasury Rate as of such date, (ii) the amount if any, by which (x)
the Stipulated Loss Value computed as of the payment date specified in such
notice (plus the amount of the deferred Basic Rent, if any, as of such date as
set forth in the column headed "Deferred Basic Rent" in Schedule SLV, and minus
the amount of prepaid Basic Rent, if any, as of such date as set forth in the
column headed "Prepaid Basic Rent" in Schedule SLV), exceeds (y) the

                                       48
<Page>

Fair Market Sales Value (determined on the basis of an arms-length transaction
between a willing seller and a willing buyer both with full knowledge of the
relevant facts, including the actual condition and maintenance status of the
Aircraft at such time) of the Aircraft as of such date, or (iii) the amount, if
any, by which (x) the aggregate Basic Rent for the remainder of the Basic Term
(or if in a Renewal Term, then until the scheduled end of the Renewal Term),
discounted periodically (equal to installment frequency) to present worth as of
the payment date using the Treasury Rate as of such date, exceeds (y) the Fair
Market Rental Value (determined in accordance with the Appraisal Procedure) of
the Aircraft for the remainder of the Basic Term (or if in a Renewal Term, then
until the scheduled end of the Renewal Term), after discounting such Fair Market
Rental Value periodically (equal to installment frequency) to present worth as
of the payment date specified in such notice using the Treasury Rate as of such
date;

          (d) In the event that Lessor, pursuant to Section 17.02(b), shall have
sold the Aircraft, Lessor, in lieu of exercising its rights under Section
17.02(c), may demand that Lessee pay Lessor, and Lessee shall pay Lessor on the
date of such sale, any unpaid Basic Rent and Supplemental Rent for the Aircraft
payable up to and including the Rent Payment Date next succeeding the date of
such sale, plus, as liquidated damages for loss of bargain and not as a penalty
(in lieu of Basic Rent for the Aircraft payable after the time of such sale),
the amount of any deficiency between the net proceeds of such sale and the
Stipulated Loss Value, computed as of the Rent Payment Date next succeeding the
date of such sale, together with interest thereon, to the extent permitted by
applicable Law, at the Interest Rate from the date as of which such Stipulated
Loss Value is computed until the date of actual payment;

          (e) In the event that Lessor, pursuant to Section 17.02(b), shall have
re-leased the Aircraft, Lessor, in lieu of exercising its rights under Section
17.02(c), may demand that Lessee pay Lessor, and Lessee shall pay Lessor, any
unpaid Basic Rent for the Aircraft payable up to the date of the Re-leasing,
plus, as liquidated damages for loss of bargain and not as a penalty (in lieu of
Basic Rent for the Aircraft payable after the time of such re-leasing (the
"RE-LEASING")), together with accrued interest thereon, if any, at the Interest
Rate to the date specified for payment, the amount, if any, by which (i) the
aggregate Basic Rent that would otherwise have become due over the Basic Term
(or if in a Renewal Term, then until the scheduled end of the Renewal Term) for
the Aircraft determined without regard to the exercise of remedies under this
Article XVII (the "ORIGINAL TERM"), discounted periodically (equal to
installment frequency) to present worth as of the date of Re-leasing using the
Treasury Rate as of such date, exceeds (ii) the sum of (A) the aggregate basic
rental payments to become due under the Re-leasing from the date of the
Re-leasing to the earlier of (x) the end of the term of the Re-leasing and (y)
the date upon which the Original Term would have expired, discounted
periodically (equal to installment frequency) to present worth as of the date of
the Re-leasing using the Treasury Rate as of such date and (B) an estimate of
Fair Market Rental Value (determined in accordance with the Appraisal Procedure)
for the period, if any, commencing on the end of the Re-leasing through the end
of the Original Term, discounted periodically (equal to installment frequency)
to present worth as of the date of the Re-leasing using the Treasury Rate as of
such date;

          (f) Proceed by appropriate court action or actions, either at law or
in equity, to enforce the performance by Lessee of the applicable covenants of
this Lease and to recover damages for the breach thereof and/or for any loss
suffered by Lessor by reason of the return of the Aircraft to Lessor otherwise
than on the last day of the Term and/or to rescind this Lease; and/or

          (g) Terminate this Lease by written notice and repossess the Aircraft.

     In addition to the foregoing, Lessee shall be liable for any and all unpaid
Basic and Supplemental Rent during or after the exercise of any of the
aforementioned remedies, together with interest on such unpaid amounts at the
Interest Rate, until Lessor shall have recovered in full the amounts payable to
Lessor under this Section 17.02 and for all reasonable legal fees and other
costs and expenses incurred by

                                       49
<Page>

Lessor (on a full indemnity basis) by reason of the occurrence of any Event of
Default or the exercise of Lessor's remedies with respect thereto including all
costs and expenses incurred in connection with the return of the Aircraft in
accordance with the terms of Article XVIII or in placing the Aircraft in the
condition and with the airworthiness certification as required by such Article
XVIII.

     In effecting any repossession of the Aircraft, Lessor and its
representatives and agents, to the extent permitted by Law, shall:

               (i) have the right to enter upon any premises which it reasonably
     believes the Aircraft, the Airframe, an Engine or a Part to be located;

               (ii) not be liable, in conversion or otherwise, for the taking of
     any personal property of Lessee that is in or attached to the Aircraft, the
     Airframe, any Engine or Part that is repossessed; PROVIDED, HOWEVER, that
     Lessor shall return to Lessee all personal property of Lessee or its
     customers that was on the Aircraft at the time Lessor re-takes possession
     of the Aircraft;

               (iii) if Lessee is either obstructing or not reasonably
     cooperating with the return to Lessor of the Aircraft or any part thereof,
     not be liable or responsible, in any manner, for any inadvertent damage or
     injury to any of Lessee's property in repossessing and holding the
     Aircraft, the Airframe, any Engine or Part, except for that directly caused
     by Lessor's gross negligence or willful misconduct;

               (iv) have the right to maintain possession of and dispose of the
     Aircraft, the Airframe, any Engine or Part on any premises owned by Lessee
     or under Lessee's control; and

               (v) have the right to obtain a key to any premises on or at which
     the Aircraft, the Airframe, any Engine or Part, may be located from the
     landlord or owner thereof.

     If required by Lessor, Lessee, at its sole expense, shall make the
Aircraft, the Airframe, any Engine or Part available at a place designated by
Lessor in accordance with Article XVIII. Lessee hereby agrees that, in the event
of the return to or repossession by Lessor of the Aircraft, the Airframe, any
Engine or Part, any rights in any warranty (express or implied) heretofore
assigned to Lessee or otherwise held by Lessee shall without further act, notice
or writing be assigned or reassigned to Lessor, if assignable. Lessee shall be
liable to Lessor for all expenses, disbursements, costs and fees incurred (i) in
repossessing, storing, preserving, shipping, maintaining, repairing and
refurbishing the Aircraft, the Airframe, any Engine or Part to the condition
required by Article XVIII and (ii) in the event of a repossession of the
Aircraft by Lessor following an Event of Default, in preparing the Aircraft, the
Airframe, any Engine or Part for sale or lease, advertising the sale or lease of
the Aircraft, the Airframe, any Engine or Part and selling or releasing the
Aircraft, the Airframe, any Engine or Part and for any reasonable expenditures
which Lessor considers advisable to repair and restore the Aircraft, the
Airframe, any Engine or Part to the condition required by Article XVIII, all at
Lessee's sole expense.

     No remedy referred to in this Section 17.02 is intended to be exclusive,
but, to the extent permissible hereunder or under applicable Law, each shall be
cumulative and in addition to any other remedy referred to 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 express or implied waiver by Lessor of any Default or Event of Default shall
in any way be, or be construed to be, a waiver of any subsequent Default or
Event of Default.

                                  ARTICLE XVIII

                             RETURN OF THE AIRCRAFT

     Section 18.01 RETURN. On the expiration of the Term or at such other time
as Lessee shall be required to return the Aircraft to Lessor pursuant to the
terms hereof, Lessee, at its own expense, shall deliver the Aircraft to Lessor
at the Return Location equipped with all required Parts and all Engines (or
Replacement Engines delivered in accordance with Section 18.03), duly installed
thereon and with all Aircraft Documents complete and up to date and in all cases
in the Return Conditions and reasonably acceptable to Lessor. The Aircraft, at
the time of return to Lessor, shall be in the same configuration as on delivery,
except as modified in accordance with the terms and conditions of this Lease and
the Return Conditions, and be fully equipped with the Engines or equivalent
engines owned by Lessee (and complying with Section 18.03) APU, landing gears
and other equipment and modifications properly installed thereon. The Aircraft
shall be in a condition suitable for immediate operation in accordance with
commercial passenger airline standards.

     Section 18.02 NO LIENS. Immediately prior to the Return Occasion, Lessee
shall, at its cost, ensure that the Aircraft, Engines and Parts are free and
clear of all Liens, except Lessor's Liens.

     Section 18.03 RETURN OF ENGINES. In the event any engine not owned by
Lessor shall be returned with the Airframe in lieu of an Engine and the reason
therefor is other than that an Event of Loss has occurred to such Engine, Lessor
shall not be obligated to accept such engine unless it meets the requirements
for a Replacement Engine, is free and clear of Liens, is suitable for use on the
Airframe with the other Engine or engine being returned with the Airframe, in
the condition required by EXHIBIT D-1 or EXHIBIT D-2, as applicable, and has an
expected useful life at least equal to, the Engine that should have been
returned, assuming such Engine which should have been returned was in the
condition and repair as required by the terms hereof immediately prior to such
required. Lessee shall, at its own expense and concurrently with such delivery,
convey such Replacement Engine to Lessor in accordance with the requirements in
Section 12.02(a). Upon full compliance with this Section 18.03 and passage of
title to such engine to Lessor, such engine shall be an Engine for all purposes
of this Lease and Lessor shall transfer to Lessee all Lessor's right, title and
interest in an Engine constituting part of the Aircraft so returned but not
installed on the Aircraft at the time of such return, without any
representation, warranty or recourse of any kind whatsoever, express or implied,
except a warranty that such Engine is free and clear of Liens created by Lessor.

     Section 18.04 CONDITION OF THE AIRCRAFT. Upon the Return Occasion, Lessee
shall, at its cost, cause the Aircraft to comply with all of the Return
Conditions.

     Section 18.05 RETURN CERTIFICATES. (a) Upon completion of the ground
inspections and the functional check flight of the Aircraft referred to in
EXHIBIT D-1 or EXHIBIT D-2, as applicable, Lessor shall either:

               (i) accept the return of the Aircraft and sign the Return
     Acceptance Certificate with any deficiencies noted thereon and deliver the
     same to Lessee; or

               (ii) if the Aircraft fails to conform to the Return Conditions,
     notify Lessee of the non-conforming items in writing.

          (b) The provisions of this Section 18.06 shall be without prejudice to
the rights or remedies of Lessor or to the obligations of Lessee under any other
provision of this Lease.

                                       51
<Page>

     Section 18.06 [Intentionally Omitted].

     Section 18.07 REGISTRATION AND DEREGISTRATION COSTS. Lessee shall be solely
responsible for any and all costs relating to the exportation and
de-registration of the Aircraft from the State of Registration (if other than
the United States), if any, in connection with the redelivery of the Aircraft to
Lessor as required hereby, including the cost of obtaining any necessary
certificates of airworthiness for export in respect of the Aircraft.

     Section 18.08 AIRPORT AND NAVIGATION CHARGES. Lessee will ensure that on
the Return Occasion, any and all airport, navigation and other charges imposed
or levied by the airport at which the Aircraft is habitually based as at the
date of the Return Occasion (if located outside the United States) that give
rise or might if unpaid give rise to any Lien, right of detention or right of
sale in relation to the Aircraft, any Engine or any Part, whether incurred in
respect of the Aircraft or any other aircraft operated by Lessee, have been paid
and discharged in full and will at Lessor's request produce evidence thereof
satisfactory to Lessor, which may include a certificate of an officer of Lessee
stating that all such outstanding airport, navigation or other charges have been
paid in full and that no such charge is being contested by Lessee.

     Section 18.09 AID IN DISPOSITION. Lessee agrees that during the last 180
days of the Term (and during the storage period set forth in Section 18.11) it
will cooperate in all reasonable respects with the efforts of Lessor to lease or
sell the Aircraft, including, without limitation, permitting potential lessees
or purchasers to inspect the Aircraft and the records relating thereto, PROVIDED
that Lessee shall not be required to incur out-of-pocket expenses for which it
is not to be reimbursed or interrupt the use and operation of the Aircraft.

     Section 18.10 STORAGE FOLLOWING RETURN OCCASION. Upon any expiration or
termination of this Lease for the Aircraft, at the written request of Lessor,
Lessee will arrange, or will cause to be arranged, secured ramp storage
facilities and storage maintenance for the Aircraft (properly insured) at an
appropriate storage area (which shall include any of Lessee's hangar facilities
suitable for such aircraft) for the Aircraft for a period not exceeding sixty
(60) days at Lessee's expense (other than for the costs of insurance and storage
maintenance, which Lessor shall reimburse to Lessee) and at Lessor's risk.
Notwithstanding other provisions of this Article 18, in the event of an Event of
Default all storage, maintenance, insurance costs and risk of loss for the
Aircraft shall be for the account of Lessee.

     Section 18.11 LESSEE'S CONTINUING OBLIGATIONS. In the event that Lessee
does not return the Aircraft to Lessor on the last day of the Term in the
condition required by Sections 18.01 through 18.04, whether as a result of any
termination under Section 17.02 or otherwise, and whether or not the reason for
such failure to return is within the control of Lessee:

             (a) the  obligations  of Lessee  under this Lease  (other  than the
payment of Basic  Rent,  which  shall be  governed  by Section  18.11(b )) shall
continue in full force and effect on a day-to-day  basis until such return,  and
the Lessee shall be obligated to continue to perform its obligations  under this
Lease,  including,  without  limitation,  the  obligation to maintain  insurance
coverages,  and the Term shall be deemed to be extended on a  day-to-day  basis,
PROVIDED  that nothing in this  paragraph  (a ) shall be deemed to  constitute a
waiver of any right that Lessor may have consequent upon any Event of Default by
Lessee; and

             (b) until such time as the Aircraft is  redelivered  in  accordance
with the Return  Conditions  or the Lessor  accepts  return of the  Aircraft and
delivers a Return Certificate  pursuant to Section 18.05,  instead of paying the
Basic Rent specified in the definition thereof, the Lessee shall pay one hundred
percent  (100%) of such Basic Rent  (calculated on a daily basis) for the period
from the date that the Aircraft was required to be returned to the date on which
it is actually returned and put into the

                                       52
<Page>

condition required by this Article XVIII and EXHIBIT D-1 or EXHIBIT D-2, as
applicable, or the Lessor accepts return of the Aircraft and delivers a Return
Certificate pursuant to Section 18.05, PROVIDED that, if Lessee's failure to
return the Aircraft is solely and directly the result of Lessor's failure to
complete any inspection and acceptance in a commercially reasonable manner, then
Lessee shall pay no Basic Rent during such delay, and during any such period,
Lessee shall not use or operate the Aircraft except as required by this Lease.
When the Lessor accepts return of the Aircraft and delivers a Return Certificate
pursuant to Section 18.05, the Term shall end and Lessee's obligations under
this Lease shall cease, except as provided in Section 20.13 hereof.

                                   ARTICLE XIX

not to be unreasonably withheld) and a Person may become Owner Trustee under the
Trust Agreement only in accordance with the provisions of Section 9.01 of the
Trust Agreement and the provisions of this Section 19.01. The appointment in any

Lease shall be binding upon and, subject to the limitations on assignment of
rights hereunder, inure to the benefit of the Lessor and the Lessee and their
respective successors and permitted assigns. Nothing herein shall be construed

     Section 19.04 PERMITTED SUBLESSEE'S PERFORMANCE AND RIGHTS. Any obligation

or cause to be performed such obligation, even if stated herein as a direct
obligation, and the performance of any such obligation by any sublessee or

under a Sublease or transfer agreement then in effect shall constitute
performance by the Lessee and to the extent of such performance discharges such
obligation by the Lessee. Except as otherwise provided in Section
8.01(c)(iii)(F) or a Sublease, a Permitted Sublessee shall have the rights
granted to the Lessee hereunder with respect to the Aircraft, Airframe and

Permitted Sublessee to exercise such rights to the extent permitted in the
relevant Sublease.

20.03, unless the Aircraft will be in danger of loss, sale, confiscation,

taking of any such action by Lessor shall not constitute a waiver or release of
any obligation of Lessee under this Lease, nor a waiver of any Default or Event

nor an election or waiver by Lessor of any remedy or right available to Lessor
under or in relation to this Lease.

two or more counterparts, each of which shall be deemed an original, but all of

any, that this Lease constitutes chattel paper (as such term is defined in the
UCC as in effect in any applicable jurisdiction) no security interest in this
Lease may be created through the transfer of possession of any counterpart other
than the original counterpart containing the receipt therefor executed by the
Lessor on the signature page thereof.

except as otherwise expressly provided herein or in the Trust Agreement or any
other Operative Document, WFB is entering into this Lease solely in its capacity
as trustee as provided in the Trust Agreement and not in its individual capacity
and in no case whatsoever will WFB be liable or accountable in its individual
capacity for any of the statements, representations, warranties, agreements or
obligations of Lessor hereunder, or for any loss in respect thereof, as to all
of which all interested parties agree to look solely to the Trust Estate;
PROVIDED that nothing in this Section 20.05 shall be deemed to limit in scope or
substance the personal liability of WFB (a) to Beneficiary as expressly set
forth in the Trust Agreement, (b) in respect of the representations, warranties
and agreements of WFB expressly made in its individual capacity herein or in any
other Operative Document to which it is a party, (c) for the consequences of its

remitting of funds only, its willful misconduct or simple negligence as a
trustee, (d) in respect of Lessor's Liens attributable to it in its individual
capacity, and (e) taxes, fees or other charges on, or based on, or measured by,
any fees, commissions or compensation received by it in connection with the
transactions contemplated by the Operative Documents.

described, or in any other manner provided by Law. Each of the parties hereto
hereby irrevocably waives, to the fullest extent permitted by Law, 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 or any other Operative
Document brought in any court in or of New York, New York, and hereby further
