                                                  AIRCRAFT LEASE AGREEMENT N0. 2

                             INSURANCE ENDORSEMENTS

          It is understood and agreed that the Saab Fairchild 340A Aircraft,
MSN-340A-006, U.S. Registration No. N360CA with two General Electric CT7-5A
Engines, serial nos. GE-E-367-122 and GE-E-367-141, respectively, and two Dowty
Rotol R354/4-123-F/13 Propellers, serial nos. DRG/7827/82 and DRG/1727/84,
respectively, is leased by Lambert Leasing, Inc., a Delaware corporation, as
lessor ("Lessor"), under Lease Agreement No. 2 dated as of March 15, 1995 (the
"Lease") to Chautauqua Airlines, Inc., as Lessee ("Named Insured").

          As provided in Part B below, Lessor and (until at least December 22,
1996) Security Pacific Equipment Leasing, Inc., as their interests may appear,
shall be Additional Insureds with respect to each policy of liability insurance
to which these endorsements are attached, and Lessor shall be the Loss Payee
with respect to each policy of "all risks" insurance to which these endorsements
are attached. With respect to the interests of each Additional Insured or Loss
Payee in and with respect to the Aircraft as defined in Section 2 of the Lease
(the "Subject Property") insured under each policy by the insurers listed in the
Schedule of Insurers attached as Annex 1 hereto (collectively, the "Company"),
the Company hereby agrees that each "all risks" 'policy includes the
endorsements in Part A below; each liability policy includes the endorsements in
Part B below; and all policies include the endorsements in Part C below:

A. LOSS PAYABLE ENDORSEMENTS (HULL POLICY)

          This "all risks" insurance is endorsed with respect to the Subject
Property, (A) to name Lessor as an additional insured, as its interests may
appear ("Additional Insured") and Lessor, as loss payee, as its interests may
appear ("Loss Payee").

1. Loss or damage, if any, to the Subject Property described in this policy to
   the extent of the Stipulated Loss Values set forth in the Stipulated Loss
   Value Table attached as Schedule 1 hereto shall be payable as follows:

                                        1
<Page>

   (i) loss or damage with respect to the Subject Property which does not
       constitute an Event of Loss (as defined in the Lease) shall be payable
       in United States Dollars solely to Lessor; except loss or damage with
       respect to the Aircraft of $ 100,000.00 or less shall be payable to Named
       Insured, unless prior to any loss or damage, Lessor notifies the Company
       that an Event of Default exists, in which case such amounts shall be
       payable to Lessor; and

   (ii) loss or damage with respect to the Subject Property described in this
       policy which constitutes an Event of Loss shall be payable by
       distributing (x) the amount set forth in Schedule 1 hereto ("SLV Amount^)
       solely to Lessor, and (y) any remaining amounts solely to Named insured.

2. Subject to paragraph 4 hereof, the insurance under this policy as to the
   interest only of the Loss Payee shall not be impaired in any way (i) by any
   action or inaction by Lessee and shall insure the interest of the Loss Payee
   regardless of any breach or violation by Lessee or any other additional
   insured of any warranty, declaration or condition contained in such policies,
   and if available at commercially reasonable cost such coverages shall be
   provided otherwise than by way of endorsement with Lloyd's Form AVN67A;
   PROVIDED HOWEVER, that with respect to secretion, embezzlement or conversion
   by Lessee, no coverage shall apply to any Person which is a willful party to
   such secretion, embezzlement or conversion, or (ii) because of a subjection
   of the Aircraft to any condition, use or operation not permitted by the
   policy or (iii) because of any false statement with respect to the policy by
   Lessee or its employees, agents or representatives, or any other Person
   except the Loss Payee (and then such policy shall be impaired only as to such
   Person), whether occurring before or after the attachment of this
   endorsement, or whether before or after the loss.

3. If the Named Insured fails to pay any premium or additional premium which
   shall be or become due under the terns of this policy, the Company agrees to
   give written notice to each Loss Payee of such nonpayment of premium and this
   policy shall continue in full force and effect if the Loss Payee when so
   notified in writing by the Company of the failure of the Named Insured to pay
   such premium, pays or causes to be paid the premium within thirty (30) days
   following receipt of the Company's written notice (seven (7) days, or such
   shorter period as may from time to time be the longest period obtainable in
   the industry, in the case of any war risk and allied perils coverage). If no
   Loss Payee pays said premium or additional premium, the rights of Agent,
   Lessor, Lessee or

                                        2
<Page>

   the Loss Payee under this Loss Payable Endorsement may be terminated by the
   Company thirty (30) days after receipt of said written notice by the Loss
   Payee (seven (7) days, or such shorter period as may from time to time be the
   longest period obtainable in the industry, in the case of any war risk and
   allied perils coverage).

4. If the Company elects to cancel this policy in whole or in part for
   nonpayment of premium or for any other reason, the Company will forward a
   copy of the cancellation notice to the Loss Payee at its office specified
   hereinafter concurrently with the sending of notice to the Named Insured but
   in such case this policy shall continue in force for the benefit of the Loss
   Payee for thirty (30) days (seven (7) days, or such shorter period as may
   from time to time be the longest period obtainable in the industry, in the
   case of any war risk and allied perils coverage) after written notice of such
   cancellation is received by the Loss Payee by a copy sent by certified or
   registered mail, return receipt requested. In no event, as to the interest
   only of the Loss Payee, shall cancellation, lapse or adverse material change
   of any insurance under this policy be effected at the request of the Named
   Insured before thirty (30) days (seven (7) days, or such shorter period as
   may from time to time be the longest period obtainable in the industry, in
   the case of any war risk and allied perils coverage) after written notice of
   request for cancellation shall have been received by the Loss Payee by a copy
   sent by certified or registered mail, return receipt requested. If this
   policy is cancelled, the unearned premium shall be paid to the Loss Payee
   that has advanced such premium.

5. The coverage provided herein is primary without contribution from any other
   insurance which might be available to the Loss Payee.

6. Whenever the Company pays to Lessor or Named Insured any sum representing a
   total loss to the Subject Property insured under this policy, and claims that
   as to the Named Insured, no liability therefor exists, the Company, at its
   option, may pay to Lessor or Named Insured, as the case may be, the
   Stipulated Loss Value (as such term is defined in the Lease and the Schedules
   attached hereto, but in no event to exceed the Agreed Inured Value as stated
   in the policy), and the Company shall thereupon be subrogated to and receive
   a full assignment and transfer, without recourse, of said obligation and the
   security held as collateral therefor; but shall not exercise such subrogation
   and assignment right until each Additional Insured has recovered in full the
   amount of its respective claims against the Named Insured.

                                        3
<Page>

7. The coverage granted under this policy shall continue in full force and
   effect as to the interest of the Loss Payee if the Loss Payee agrees to pay
   the premium therefor, for a period of thirty (30) days after expiration of
   said policy unless an acceptable policy in renewal thereof with loss
   thereunder payable in accordance with the terms of this Loss Payable
   Endorsement shall have been issued by an insurance company acceptable to
   Lessor.

8. Should this policy be continued for the term hereof for the benefit of the
   Loss Payee (with all incidents of ownership of the policy), Paragraphs 2, 6
   and 7 of Part A of this Loss Payable Endorsement shall no longer apply to the
   Loss Payee; PROVIDED, NEVERTHELESS, all privileges and endorsements which, by
   reason of the printed conditions of this policy, are or may be necessary to
   maintain the validity of the contract are hereby granted for a period of
   thirty (30) days, and all notices likewise required to be given to the
   company by Named Insured are hereby waived for a period of thirty (30) days
   with the exception of requirements applying at the time of or subsequent to a
   loss.

9. The Company waives any rights of subrogation against the Loss Payee, to the
   same extent as Lessee has waived its right against the Loss Payee, except
   with respect to the gross negligence and/or willful misconduct of the Loss
   Payee; PROVIDED, that with respect to liability and property damage coverages
   hereunder such waiver shall not operate to prejudice the Company's rights of
   recourse against Saab Aircraft AB and/or Saab Aircraft of America, Inc.,
   and/or any subsidiary thereof and General Electric Company and/or any
   subsidiary thereof, as manufacturers, repairers, suppliers or servicing
   agents (other than financial services) where such rights of recourse would
   have existed had such waiver not been given; and PROVIDED, FURTHER, that the
   exercise by the Company of rights of subrogation derived from rights retained
   by Named Insured shall not, in any way, delay payment of any claim that would
   otherwise be payable by the Company but for the existence of rights of
   subrogation derived from rights retained by Named Insured.

B. LIABILITY POLICY ENDORSEMENTS

          This liability insurance policy is endorsed, with respect to the
Subject Property:

(A) To name Lessor and (until at least December 22, 1996) Security Pacific
    Equipment Leasing, Inc. as additional insureds as

                                        4
<Page>

    their respective interests may appear ("Additional Insureds") and shall
    cover (i) each of the shareholders of each Additional insured, and (ii)
    officers, directors, employees, agents and representatives of each
    Additional insured (with respect to each Additional Insured, collectively,
    "Covered Persons");

(B) To provide that if this policy is cancelled for any reason whatsoever, or
    any substantial change is made in the coverage which affects the interest of
    the Additional Insureds and Covered Persons, or if such insurance is
    cancelled for nonpayment of premium or allowed to lapse, such cancellation,
    change or lapse shall not be effective as to the Additional Insureds and
    Covered Persons thirty (30) days (seven (7) days, or such shorter period as
    may from time to time be the longest period obtainable in the industry, in
    the case of war risk and allied perils coverage) after receipt by such
    Additional Insureds of written notice from the Company sent by certified or
    registered mail, return receipt requested, of such cancellation, change or
    lapse;

(C) To provide that if the Named Insured fails to pay any premium or additional
    premium which shall be or become due under the terms of this policy, the
    Company agrees to give written notice to each Additional Insured of such
    nonpayment of premium and this policy shall continue in full force and
    effect if any one or more of the Additional Insureds when so notified in
    writing by the Company of the failure of the Named Insured to pay such
    premium, pays or causes to be paid the premium due within thirty (30) days
    following receipt of the Company's written notice. If no Additional Insured
    pays said premium or additional premium, the rights of Lessor and other
    Additional Insureds and Covered Persons under this Liability Endorsement may
    be terminated by the Company thirty (30) days after receipt of said written
    notice by each Additional Insured;

(D) To provide that the Coverage granted under this policy shall continue in
    full force and effect as to the interest of each Additional Insured and
    Covered Person if any Additional Insured agrees to pay the premium therefor,
    for a period of thirty (30) days after expiration of said policy unless an
    acceptable policy in renewal thereof shall have been issued by an insurance
    company acceptable to Lessor;

(E) To provide that in respect of the interest of the Additional Insureds and
    Covered Persons, (i) this policy shall not be invalidated by any action of
    Named Insured and shall insure the respective interests of the Additional
    Insureds and Covered Persons named and covered under this Endorsement, as

                                        5
<Page>

    they appear, regardless of any breach or violation by Named Insured of any
    warranties, declarations or conditions contained in this policy or in the
    application therefor, if any, and (ii) severability of interest is included,
    PROVIDED nothing herein shall operate to increase the limits of liability
    and that coverage provided herein is primary without contribution from any
    other insurance which might be available to the Additional Insureds, and
    (iii) this insurance shall provide the same protection to each insured
    hereunder as would have been available had this policy been issued
    separately to each insured, except that in no event shall the Company's
    total liability exceed $100,000,000.00;

(F) the Company waives any rights of subrogation against any Additional Insured
    and the Covered Persons of such Additional Insured to the same extent as
    Lessee has waived its right against such Additional Insured and the Covered
    Persons of such Additional insured, except with respect to the gross
    negligence and/or willful misconduct of such party; PROVIDED, that with
    respect to liability and property damage coverages hereunder such waiver
    shall not operate to prejudice the Company's rights of recourse against Saab
    Aircraft AB and/or Saab Aircraft of America, Inc., and/or any subsidiary
    thereof as manufacturers, repairers, suppliers or servicing agents (other
    than financial services) where such rights of recourse would have existed
    had such waiver not been given, and PROVIDED, FURTHER, that the exercise by
    the Company of rights of subrogation derived from rights retained by Named
    Insured shall not, in any way, delay payment of any claim that would
    otherwise be payable by the Company but for the existence of rights of
    subrogation derived from rights retained by Named Insured; and

(G) to insure the Additional Insureds and the Covered Persons with respect to
    liability for matters which are the subject of Named Insured's obligations
    under the Lease and Lessee Documents to the extent such insurance is
    provided under this policy; and to provide that such Additional Insureds and
    Covered Persons are warranted to have no operational interest.

          Nothing in these Insurance Endorsements shall be deemed or construed
to be an agreement by the Company to insure the Manufacturer of the Aircraft,
Saab Aircraft AB, or the manufacturer of the engines, General Electric Company,
against claims arising out of product liability.

Section 10. INTEREST OF LESSOR: LIENS; NAMEPLATES.

     10.1 LIENS. Sublessee and Sublessor agree that for all purposes, this
Sublease is, and is intended to be, a Sublease, and that Sublessee does not
acquire any right, title, interest or equity in or to the Aircraft, except the
right to use it under the terms provided herein. The Aircraft, excluding those
additions to which Sublessee retains title, is and shall at all times, until
released, remain the sole and exclusive property of Lessor, subject only, FIRST,
to the Lien of the Loan Agreement, and SECOND, to the interest of Sublessor
under the Lease (and subject to any other Permitted Liens). The only interest
Sublessee shall have in the Aircraft is that of a sublessee hereunder.

     Sublessee shall not directly or indirectly create, incur, assume or suffer
to exist any Lien on or with respect to the Aircraft, any part thereof, title
thereto or any interest therein, and in this Sublease or in any Rent, except (a)

under the Operative Documents; (b) the rights under the Operative Documents of
the respective parties thereto; (c) the rights of others under agreements or

Sublessor Liens or Lender Liens, including the Lien of the Loan Agreement; (e)
Liens for taxes of Sublessee either not yet delinquent or being contested in
good faith by appropriate and timely proceedings, so long as such proceedings do
not involve any material danger of the sale, forfeiture or loss of or
interference with the use of the Aircraft, the Airframe or any Engine or
Propeller or any interest therein; PROVIDED, that Sublessee shall maintain on
its books any reserves with respect thereto which may be required by GAAP; (f)
inchoate materialmen's, mechanics', workers', repairers',

                                       12
<Page>

employees' or other like Liens arising in the ordinary course of Sublessee's
business for amounts the payment of which is either not yet delinquent or is
being contested in good faith by appropriate proceedings so long as such
proceedings do not involve any material danger of the sale, forfeiture or loss
or interference with the use of the Aircraft, or any interest therein; PROVIDED,
that Sublessee shall maintain on its books any reserves with respect thereto
which may be required by GAAP; (g) Liens arising out of the maintenance of court
actions being defended in good faith and on a timely basis and Liens arising out
of judgments or awards against Sublessee with respect to which an appeal or
proceeding for review is being prosecuted in good faith and with respect to
which there is secured a stay of execution pending such appeal, or proceeding
for review; and (h) any other Lien with respect to which Sublessee provides a
bond in an amount and under such terms as are adequate in the reasonable
opinion of Sublessor; PROVIDED, that the aggregate amount of liens which are not
being contested and are delinquent under paragraphs (e), (f), and (g) of this
SECTION 10.1 for which no bond or adequate (in the reasonable opinion of
Sublessor) security is provided shall not at any time exceed $25,000.00. For the
purpose hereof, the Liens set forth in clauses (a) through (h) of this SECTION
10.1 shall be "Permitted Liens". Sublessee at its own cost and expense will
protect and defend the Aircraft and any interest therein against all Liens,
other than Permitted Liens, and legal processes of the creditors of the
Sublessee and other Persons, other than Permitted Liens, and Sublessee will
promptly, at its own expense, take such action as may be necessary to duly
discharge any such Lien not permitted by the express terms above if the same
arises at any time.

     10.2 NAMEPLATE. Sublessee shall attach to and keep upon the Airframe and
each Engine such labels, plates or markings furnished by Sublessor as are deemed
by Sublessor necessary or advisable to evidence Lessor's ownership thereof; and
in any event Sublessee will cause to be affixed to and maintained on the
Aircraft in a location adjacent to and not less prominent than that of the
Airworthiness Certificate, and on each Engine a nameplate furnished by Sublessor
bearing the following legend:

     "LEASED FROM WILMINGTON TRUST COMPANY, AS OWNER TRUSTEE AND LESSOR; SUBJECT
     TO A FIRST PRIORITY SECURITY INTEREST IN FAVOR OF MELLON FINANCIAL SERVICES
     CORPORATION #3 AND SUBLEASED FROM FAIRBROOK LEASING, INC.",

such nameplate also to state, to the extent applicable, the type, manufacturer's
serial number and current registration number of the Airframe. Sublessor and
Sublessee agree that the nameplate shall be changed by Sublessor to reflect any
transfer of the interests of Lessor or Lender in accordance with the Operative
Documents. Except as above provided, Sublessee will not allow the name of any
Person to be placed on the Aircraft with any description that might be
interpreted as a claim of ownership or of security interest

                                       13
<Page>

therein; PROVIDED, HOWEVER, that nothing herein contained shall prohibit
Sublessee from placing its customary colors and insignia and name an the
Aircraft, or from substituting engines, propellers or parts an the Aircraft in
accordance with this Sublease.

     Sublessor or any other Person in causing any termination of the Lease to be
     recorded at the FAA Aircraft Registry upon its expiration or termination;

          (ii) promptly deliver to Sublessor, Lessor and Lender true copies of
     all applications made by Sublessee in relation to the Aircraft, of all
     certificates of registration issued pursuant to such applications and of
     all notifications given pursuant to such registrations (including without
     limitation, notification of changes in Sublessee's maintenance program) and
     shall not do, or permit to be done by any Person, any act which might cause
     the Aircraft to be ineligible for registration with the FAA, subject to

     other Person as may reasonably be required and, to the extent then so
     required, to Lessor remaining a "citizen of the United States" as defined

     Aircraft (including corrosion control) in compliance with the Maintenance

<Page>

     when delivered to Sublessee hereunder, ordinary wear and tear excepted, and
     in a condition suitable for airline commercial use (but with no broken,
     damaged or missing items or components except obsolete parts and/or parts
     undergoing replacement or scheduled to be replaced), (C) in such a manner
     as may be necessary to maintain in full force all warranties of
     manufacturers and suppliers of the Aircraft and its components, in
     accordance with their respective terms, and (D) in such operating condition
     as may be necessary to enable the airworthiness certification of the
     Aircraft to be maintained in good standing at all times under the
     Transportation Code and the Aircraft to be eligible for operation in
     regularly scheduled United States commercial passenger service under FAR
     Part 135 or successor provisions, as may be applicable, but in any event in
     a manner, to an extent and with a standard of care and frequency of
     maintenance not less than that employed by Sublessee with respect to
     similar aircraft and engines owned or leased by it and without regard to
     any scheduled return of the Aircraft pursuant hereto, which practices shall
     at all times be at or above the standard of the industry for maintenance of
     similar aircraft; PROVIDED, HOWEVER, that Sublessee shall not be deemed to
     be in violation of its obligations under this clause (iii) with respect to
     any minor violation which is cured promptly after Sublessee becomes aware
     of it, and in any event not later than sixty (60) days after Sublessee
     becomes aware of it, so long as such minor violations do not affect or
     impair the registration or eligibility for registration of the Aircraft;
     and maintain all records, logs and other materials required by the
     appropriate authorities of the jurisdiction where the Aircraft is
     registered to be maintained in respect of the Aircraft, and permit
     Sublessor, Lessor and, until the earlier of (A) delivery of the Release
     Notice (B) return of the Aircraft to Sublessor or Lessor or (C) the sale of
     the Aircraft pursuant to any provision hereof, Lender, to examine such
     records at any reasonable time during normal business hours;

          (iv) upon their request, promptly furnish to Lessor or Sublessor
     notification of any material changes in the Sublessee's Maintenance
     Program, and such other information as may be required to enable Sublessor,
     Lessor or Lender to file any reports required by any Governmental Body as a
     result of the interests of Sublessor, Lessor or Lender in the Aircraft;

          (v) pay and provide for all electric power, oil, fuel and lubricant
     consumed by and required for the operation of the Aircraft, and all
     repairs, parts and supplies necessary therefor;

                                       15
<Page>

          (vi) except as otherwise provided herein, comply with all applicable
     mandatory (A) FAA airworthiness directives, orders and other requirements
     of FAR Part 135 or successor provisions, as may be applicable, (B)
     manufacturer service bulletins and service letters or similar requirements
     affecting the Aircraft, and (C) rules and regulations of the FAA relating
     to the Aircraft, and take all steps necessary so that the Aircraft at all
     times during the Term possesses a valid FAA Airworthiness Certificate in
     good standing and that the Aircraft remains eligible for operation in
     regularly scheduled United States commercial passenger service under FAR
     Part 135 or successor provisions, as may be applicable, except as provided
     for in SECTION 12.2 (vi);

          (vii) conform with any Applicable Law requiring alteration of the
     Aircraft (or obtain a waiver of conformance therewith at no expense to
     Lessor or Sublessor) and maintain the same in proper operating condition
     under such Applicable Law; PROVIDED, HOWEVER, that Sublessee may, with the
     consent of Sublessor, in good faith contest the validity or application of
     any such Applicable Law, after having delivered to Sublessor written notice
     stating the facts with respect thereto, and so long as such contest does
     not subject Sublessor, Lessor or Lender to criminal liability and does not
     subject the Aircraft or any interest therein to any material danger of
     sale, forfeiture or loss;

          (viii) cause the Aircraft to be operated only by duly-qualified,
     currently certificated pilots having the minimum total pilot hours required
     by any policy of insurance required to be carried hereunder and for such
     certification by the FAA;

          (ix) not maintain, use, operate or locate the Aircraft (A) in
     violation of any Applicable Law, or in violation of any airworthiness
     certificate, license or registration relating to the Aircraft issued by any
     Governmental Body; (B) in any area excluded from coverage by any insurance
     in effect or required to be maintained by the terms of SECTION 13, except
     in the case of requisition by the United States Government, where Sublessee
     obtains, for the benefit of Lessor, Sublessor, Lender and each Bank,
     indemnity in lieu of such insurance from the United States Government
     against the risks and in the amounts required by SECTION 13 covering such
     area; (C) outside of, or to any destination outside of the United States,
     except (1) in connection with the delivery of the Aircraft or any part
     thereof to the Manufacturer for any service, repair, modification or
     alteration required or permitted hereunder, to the extent not reasonably
     capable of being performed in the United States, (2) when the Aircraft is
     operated or used under contract with the United States Government under
     which contract the United States Government assumes liability for

                                       16
<Page>

     any damage, loss, destruction or failure to return possession of the
     Aircraft at the end of the term of such contract and for injury to persons
     or damage to property of others, or (3) to destinations within Canada,
     Mexico and the Caribbean, so long as the total annual operating time of the
     Aircraft (on a calendar year basis) outside of the continental limits of
     the United States shall not exceed fifty percent (50%) of the total annual
     operating time of the Aircraft for any calendar year prior to January 1,
     1999 and to the extent that such use does not violate the restrictions set
     forth in SECTION 11.1(xi)hereof;

          (x) perform in due course terminating actions with respect to any part
     of the Aircraft affected by an FAA airworthiness directive if terminating
     action is performed with respect to similar items of aircraft or equipment
     owned or leased by Sublessee, except for those airworthiness directives
     whose final compliance date is later than twelve (12) months after the
     expiration of the Term of this Sublease, and not defer maintenance or
     replacement of parts, preventative maintenance (including corrosion
     control) or implementation of FAA airworthiness directives that Sublessee
     in accordance with its ordinary practice would have performed without
     regard to any scheduled return of the Aircraft pursuant hereto, or install
     replacement components with excessive wear, or except as otherwise provided
     in SECTION 19, exchange any Engine, Propeller, landing gear or any other
     Part of the Aircraft about to be returned to Sublessor for other aircraft
     components in Sublessee's possession for use on aircraft that will remain
     in Sublessee's or any Affiliate of Sublessee's possession after such return
     in order to reduce or avoid future maintenance requirements; and

          (xi) not allow the Aircraft Base for the Aircraft at any time to be a
     location other than Indianapolis, Indiana or Akron, Ohio without thirty
     (30) days' prior written notice to Lessor, Sublessor and, until the Release
     Notice is delivered, Lender.

          11.2 POSSESSION. Except as provided in this SECTION 11 or SECTION 20,
Sublessee will not, without the prior written consent of Sublessor, sub-sublease
or otherwise in any manner deliver, transfer or voluntarily relinquish
possession, or enter into any contract or arrangement obligating it to deliver,
transfer or relinquish possession of the Airframe, any part thereof, any Engine
or Propeller or install any part of the Airframe, any Engine or Propeller or
permit any part of the Airframe, any Engine or Propeller to be installed, on any
airframe other than the Airframe, except as provided in this SECTION 11 or
SECTION 20, except that so long as no Default or Event of Default exists, and so
long as the action to be taken does not affect the Lien of the Loan Agreement
with respect to, Lessor's title to or interest in, or Sublessor's

                                       17
<Page>

interest in, the Aircraft, Sublessee may, without the prior written consent of
Sublessor:

          (i) subject any Engine or Propeller to normal interchange or pooling
agreements or arrangements customary in the airline industry applicable to other
similar engines or propellers operated by Sublessee and entered into by
Sublessee in the ordinary course of its business; PROVIDED, (A) if Lessor's
title to any such Engine or Propeller is divested pursuant to any such agreement
or arrangement or (B) if Sublessee relinquishes possession of such Engine or
Propeller for a continuous period of more than one hundred eighty (180)
consecutive days, there shall be deemed to be an Event of Loss with respect to
such Engine or Propeller and Sublessee shall comply with SECTION 12.4 in respect
thereof;

          (ii) deliver possession of the Aircraft, or any component thereof, to
the manufacturer thereof or its authorized representatives for testing or other
similar purpose or to any organization for service, repair, maintenance or
overhaul work on the Aircraft or any part thereof or for alterations or
modifications in or additions to the Aircraft to the extent required or
permitted by the terms of this Sublease;

          (iii) install an Engine or a Propeller on an airframe owned by
Sublessee free and clear of all Liens, except (A) Liens of the type permitted
under SECTIONS 10.1 (e), (f) AND (g), (B) the rights of other U.S. Certificated
Air Carriers under normal interchange agreements that are customary in the
airline industry and entered into by Sublessee in the ordinary course of its
business, so long as such agreements do not contemplate, permit or require the
transfer of title to such airframe or the engines or the propellers installed
thereon and (C) the Lien of any mortgage which expressly and effectively
provides that each Engine or Propeller shall not become subject to the Lien
thereof, notwithstanding the installation thereof on an airframe or engine
subject to the Lien of such mortgage, unless and until Sublessee shall become
the owner of such Engine or Propeller free of the respective interests of
Lessor, Sublessor and Sublessee therein under this Sublease and the Lien of the
Loan Agreement;

          (iv) install an Engine or a Propeller on an airframe leased to
Sublessee or purchased by Sublessee subject to a conditional sale or other
security agreement, PROVIDED (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 and their purchasers, mortgagees and encumbrancers covering
such airframe and except Liens of the type permitted by clauses (A) and (B) of
subparagraph (iii) of this SECTION 11.2; and (B) such lease, conditional sale or
other security agreement expressly and effectively provides that each Engine or
Propeller shall not become subject to the Lien of such lease, conditional sale
or other security agreement, notwithstanding the installation

                                       18
<Page>

thereof on any airframe subject to the Lien of such lease, conditional sale or
other security agreement, unless and until Sublessee becomes the owner of such
Engine or Propeller free of the respective interests of Lessor, Sublessor and
Sublessee therein under this Sublease and the Lien of the Loan Agreement; or

          (v) transfer possession of the Airframe or any Engine or Propeller to
the United States Government pursuant to a sub-sublease, a copy of which shall
be promptly furnished to Sublessor; PROVIDED, that such sub-sublease (including,
without limitation, any option of the sub-sublessee to renew or extend) shall
not extend beyond the end of the Term for the Aircraft of which such Airframe
or Engine or Propeller is part.

          Notwithstanding anything to the contrary in this SECTION 11.2:

          (1) the rights of any transferee or sub-sublessee who receives
possession by reason of a transfer permitted by this SECTION 11.2 (other than a
transfer of an Engine or Propeller which is deemed an Event of Loss) are and
shall be EXPRESSLY subject and subordinate to all the terms of this Sublease
during the Term hereof, to the Lease and to the Lien of the `Loan Agreement,
including without limitation, in each instance, Sublessor's rights to
repossession pursuant to SECTION 18, and Lender's or Lessor's rights to
possession pursuant to SECTION 20.4, and to avoid such transferee's or
sub-sublessee's right to possession upon such repossession;

          (2) Sublessee shall remain primarily liable hereunder for the
performance of all the terms of this Sublease to the same extent as if such
transfer or sub-sublease had not occurred; and

          (3) No interchange agreement, sub-sublease or other relinquishment of
possession of the Airframe, any Engine or Propeller shall in any way affect the
registration of the Aircraft with the FAA, or discharge or diminish any of
Sublessee's obligations to Sublessor or constitute a waiver of any of
Sublessor's rights and remedies hereunder, Lessor's rights and remedies under
the Lease, and Lessor's and Lender's rights and remedies under the Operative
Documents. If a lease, conditional sale, or other security agreement complies
with clause (B) of subparagraph (iv) of this SECTION 11.2, and the lease or
conditional sale or other security agreement covering such airframe also covers
an engine or engines or propeller or propellers owned by the lessor under such
lease or subject to a security interest in favor of such secured party under
such conditional sale or other security agreement, neither Sublessor nor Lessor
will acquire or claim, as against such lessor or secured party, any right, title
or interest in any such engine or propeller as the result of such engine or
propeller being installed on the Airframe or any

                                       19
<Page>

propeller being attached to any Engine at any time while such engine or
propeller is subject to such lease or conditional sale or other security
agreement and owned by such lessor or subject to a security interest in favor of
such secured party. Sublessor also hereby agrees for the benefit of the
mortgagee under any mortgage complying with clause (C) of subparagraph (iii) of
this SECTION 11.2 that Lessor will not acquire or claim, as against such
mortgagee, any right, title or interest in any engine or propeller subject to
the lien of such mortgage as the result of such engine being installed on the
Airframe or such propeller being installed on the Airframe or any Engine at any
time while such engine or propeller is subject to the lien of such mortgage.

          11.3 REPORTS AND RECORDS. Throughout the Term, Sublessee shall keep
accurate, complete and current records in English complying with the
requirements of the FAA, so as to enable operation of the Aircraft under FAR
Part 135 or successor provisions, as may be applicable, and any other applicable
regulations from time to time in force; with recommendations of Manufacturer,
GE, Dowty or any other manufacturer or supplier of any Aircraft component; and
with good commercial airline practice of all maintenance carried out with
respect to the Aircraft, and subject to the terms and conditions in SECTION
17.1, shall permit Sublessor, Lessor, and until delivery of the Release Notice,
Lender, or any authorized representative of Sublessor, Lessor or, until delivery
of the Release Notice, Lender to examine such records requested by them at any
reasonable time.

          11.4 REPLACEMENT OF PARTS. Sublessee, at its own cost and expense,
will promptly replace all Parts which are installed in or attached to the
Aircraft which may from time to time become worn out, lost, stolen, destroyed,
seized, confiscated, damaged beyond repair or permanently rendered unfit for use
for any reason whatsoever except as provided in SECTION 11.6. In addition,
Sublessee may, in the ordinary course of maintenance, service, repair, overhaul
or testing, at its own cost and expense, remove any Parts, whether or not worn
out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or
permanently rendered unfit for use; PROVIDED that Sublessee, except as provided
in SECTION 11.6 shall, at its own cost and expense, repair and reinstall or
replace such Parts as promptly as possible. All replacement Parts shall be free
and clear of all Liens (except for Permitted Liens and interchange and pooling
arrangements to the extent permitted by SECTIONS 10.1 AND 11.2); shall comply
with the safety, general operating and flight regulations of the FAA and other
Governmental Bodies having jurisdiction over the Sublessee, the Aircraft or any
component of the Aircraft; and shall be in as good operating condition as, and
shall have a value, utility and remaining useful life at least equal to, the
Parts replaced based upon the assumption that such replaced Parts were in the
condition and repair required to be maintained by the terms hereof. Sublessee
shall maintain all required safety equipment and instruments on the

                                       20
<Page>

Aircraft and its component parts.

          All Parts at any time removed from the Airframe or any Engine or
Propeller shall remain the property of Lessor and subject to the Lien of the
Loan Agreement no matter where located, until such time as such Parts are
replaced by Parts that have been incorporated or installed in or attached to the
Airframe or any Engine or Propeller and that meet the requirements for
replacement Parts specified above. Immediately upon any replacement Parts
becoming incorporated or installed in or attached to the Airframe or any Engine
or Propeller as above provided, without further act, (i) title to the replaced
Part shall thereupon vest in Sublessee, free and clear of the rights of Lessor,
Lender, and Sublessor and shall no longer be deemed a Part hereunder, (ii) title
to such replacement Part shall thereupon vest in Lessor (subject only to
Permitted Liens and interchange and pooling arrangements to the extent permitted
by SECTIONS 10.1 AND 11.2), and (iii) such replacement Part shall become subject
to this Sublease and be deemed a part of the Airframe or any Engine or Propeller
for all purposes hereof to the same extent as the Parts originally incorporated
or installed in or attached to the Airframe or any Engine or Propeller.

          11.5 POOLING OF PARTS. Any Part removed from the Airframe or any
Engine or Propeller as provided in SECTION 11.2 may be subjected by Sublessee to
a normal interchange or pooling arrangement customary in the airline industry
entered into in the ordinary course of Sublessee's business with other U.S.
Certificated Air Carriers; PROVIDED that no such agreement or arrangement
contemplates or requires the transfer of title of such Part and PROVIDED that
the Part replacing such removed Part shall be incorporated or installed in or
attached to the Airframe or any Engine or Propeller in accordance with SECTION
11.4 as promptly as possible 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 or Propeller in accordance with SECTION 11.4 may be
owned by a U.S. Certificated Air Carrier subject to such normal pooling
arrangement; PROVIDED that Sublessee, at its expense, as promptly thereafter as
possible, either (i) causes title to the replacement Part to vest in Lessor in
accordance with SECTION 11.4, by Sublessee acquiring title thereto and
transferring title thereto to Lessor, free and clear of all Liens except
Permitted Liens in accordance with the last sentence of SECTION 11.4, or (ii)
replaces such replacement Part by incorporating or installing in or attaching to
the Airframe, any Engine or Propeller, a further replacement Part owned by
Sublessee, free and clear of all Liens except Permitted Liens and by causing
title to the replacement Part to vest in Lessor in accordance with SECTION 11.4.

          11.6 ALTERATIONS, MODIFICATIONS AND ADDITIONS. Except as otherwise
required by SECTION 11.1 or by this SECTION 11.6,

                                       21
<Page>

Sublessee shall not make any alterations, modifications or, additions to the
Aircraft without the prior written consent of Sublessor which approval shall not
be unreasonably withheld or delayed, PROVIDED, HOWEVER Sublessee shall make, or
shall cause to be made, at no expense to Sublessor or Lessor, such alterations
and modifications in and additions to the Aircraft as may be required from time
to time by the FAA or other Governmental Body having jurisdiction or as may be
required by Applicable Law as a condition to the use of the Aircraft in ordinary
commercial passenger service, and FURTHER, PROVIDED, Sublessee may, at its own
expense and subject to compliance with the requirements of Revenue Procedure
79-48, 1979-2 C.B. 529 from time to time make such alterations, modifications or
additions to the Aircraft as Sublessee may deem desirable in the proper conduct
of its business, so long as such alteration, modification or addition does not
diminish the value, utility or remaining useful life of such item, or impair the
condition and airworthiness thereof, below the value, utility, remaining useful
life, condition and airworthiness thereof immediately prior to such alteration,
modification or addition based upon the assumption that such item was then of
the value and utility and in the condition and airworthiness required to be
maintained by the terms of this Sublease; but if the cost of such alteration,
modification or improvement exceeds $75,000 and is not required by this SECTION
11 and is neither safety-related nor, severable as defined in SECTION 4(4). 02
of Revenue Procedure 75-21, as modified by Revenue Procedure 79-48; and is not
described in subparagraph (ii) of SECTION 4(4).03 (c) of Revenue Procedure
75-21, 1975-1 C.B. 715 as modified by Revenue Procedure 79-48, such alteration,
modification or addition shall not be made without the prior written consent of
Sublessor which shall not be given without receipt by Sublessor of written
consent of Lessor and Lender, and otherwise in compliance with the requirements
of SECTION 4(4).03(c) of Revenue Procedure 75-21, as modified by Revenue
Procedure 79-48. Sublessor may condition such consent on the agreement by
Sublessee at its sole expense to remove such alterations, modifications or
additions and to restore the Aircraft to its original condition upon the
expiration or termination of this Sublease. Title to all Parts incorporated in
the Aircraft as the result of any alteration, modification or addition made as
contemplated in this SECTION 11.6 shall, except as provided in Revenue Procedure
79-48, without further act, vest in Lessor, and in either case, shall become
subject to this Sublease. So long as no Default or Event of Default exists, or
if such Default exists but has not matured into an Event of Default and
Sublessor has not withheld its consent (which Sublessor agrees it will not
unreasonably withhold), upon a written request from Sublessee, Sublessee may
remove any such Part if (i) such part is in addition to, and not in replacement
of or in substitution for, any Part originally incorporated or intended to be
incorporated in the Aircraft at the time of delivery thereof hereunder or any
Part in replacement of, or substitution for, any such original Part, unless such
original Part is removed and returned pursuant to SECTION 11, (ii) such Part is
not required to

                                       22
<Page>

be incorporated in the Aircraft pursuant to SECTION 11 OR 19, and (iii) such
Part can be removed without diminishing or impairing the value, utility,
appearance, remaining useful life, condition or airworthiness which the Aircraft
would have had at such time had such alteration, modification or addition not
occurred. Upon any such removal, title to such Part shall, without further act,
vest in the Sublessee, free of the Lien of the Loan Agreement, Lessor Liens and
Sublessor Liens, and such Part shall no longer be deemed to be a Part hereunder.
Any Part not so removed prior to the return to Sublessor hereunder of the
Aircraft shall remain the property of Lessor and subject to this Sublease.

          Sublessee shall provide Sublessor and Lessor not less than one hundred
eighty (180) days prior to the end of the Term, with a list of all Parts which
Sublessee believes it is entitled to and intends to remove at such expiration
date or termination. Sublessor or Lessor shall have the option, exercisable upon
written notice given to Sublessee not more than ninety (90) days and not less
than thirty (30) days prior to the expiration of this Sublease, or upon
termination of this Sublease under SECTION 18, to purchase for cash any and all
such Parts which may be owned by Sublessee at the expiration or other
termination of this Sublease for an amount equal to the Fair Market Sale Value
thereof at such time.

          Sublessee shall cause all Parts owned by it during the Term of this
Sublease to remain free and clear of all Liens except Permitted Liens.

SECTION 1.2.  RISK OF LOSS: EVENT OF LOSS AND CONDEMNATION.

          12.1 RISK OF LOSS. Upon execution and delivery of Sublease Supplement
No.1 and commencing on the Delivery Date and continuing until the expiration or
earlier termination of this Sublease and the earlier of either (i) the return by
Sublessee of the Aircraft to Sublessor subject to SECTION 19.1, or (ii)
commencement of the storage period set forth in SECTION l9.6,(except in
connection with a cancellation pursuant to SECTION 18), Sublessee assumes the
entire risk of loss of the Aircraft or any part thereof or of any Event of Loss
as defined below or any liability arising out of the operation, maintenance,
use, storage, overhaul, repair, transport or possession of the Aircraft or any
other cause whatsoever, and no Event of Loss or liability shall relieve
Sublessee of its obligations hereunder except as provided herein.

          12.2 EVENT LOSS - DEFINITION. For all purposes of this Sublease, any
of the following events with respect to the Aircraft, Airframe, or any Engine or
Propeller subleased hereunder shall be an Event of Loss:

     (i) loss of such property or the use thereof due to theft or

                                       23
<Page>

disappearance for a period greater than forty-five (45) consecutive days or
extending beyond the end of the Term;

     (ii) loss of such property or the use thereof due to destruction, damage
beyond repair or rendition of such property permanently unit for normal use by
Sublessee for any reason whatsoever;

     (iii) any damage to such property which should or does result in the
receipt of insurance proceeds under the policies of insurance required to be
maintained pursuant to SECTION 13 hereof with respect to such property on the
basis of a total loss or constructive total loss;

     (iv) the condemnation, taking, confiscation or seizure of, or requisition
of title to such property by any Governmental Body;

     (v) the condemnation, taking, confiscation or seizure of the use of such
property for a period in excess of ninety (90) consecutive days or a period
extending beyond the end of the Term, other than a requisition for use by the
United States Government that does not continue beyond the end of the Term;
PROVIDED that pursuant to such requisition the United States Government agrees
to make payments sufficient in amount for the discharge of the obligations of
Sublessee hereunder to pay Rent, or Sublessee provides other security reasonably
acceptable to Sublessor (which consent shall not be given without the consent of
the Lender until delivery of the Release Notice) if the United States Government
does not so agree to make such payments, and PROVIDED, FURTHER, that the United
States Government agrees to maintain the Aircraft to a standard which is at
least as rigorous as set forth in this Sublease;

     (vi) as a result of any rule, regulation, order or other action (generally
applicable to aircraft of the same type as the Aircraft) by the FAA, the
Department of Transportation or other Governmental Body (including any court)
having jurisdiction, the use of such property in the normal course of interstate
air transportation of persons is prohibited for a period of six (6) consecutive
months or, if earlier, beyond the end of the Term, unless Sublessee, prior to
the expiration of such six (6) consecutive month period (or such shorter period
extending beyond the end of the Term), undertakes and is diligently carrying
forward all steps necessary or desirable to permit the normal use of such
property by Sublessee or, in any event, if such use is prohibited for a period
of twelve (12) consecutive months;

     (vii) with respect to the Aircraft, Airframe or any Engine or Propeller,
the operation or location thereof, while under requisition for use by the United
States Government, in any area excluded from coverage by any insurance policy in
effect with respect thereto required by SECTION 13 hereof if Sublessee is

                                       24
<Page>

unable to obtain indemnity or insurance in lieu thereof in a manner reasonably
satisfactory to Sublessor from the United States Government; or

     (viii) the FAA deregisters the Aircraft (other than as a result of (A) the
failure of Lessor to cooperate with Sublessee to the extent reasonably required
to maintain United States registration of the Aircraft, (B) to the extent then
so required for the purpose of maintaining United States registration of the
Aircraft, the failure of Lessor to remain a "citizen of the United States" as
defined in SECTION 40102 (a)(15) of the Transportation Code, or (C) Lessor
otherwise causing the Aircraft to be ineligible for such registration by reason
of its interest therein) and such deregistration continues for a period of one
hundred eighty (180) consecutive days.

          An Event of Loss with respect to the Aircraft shall also be deemed to
occur if an Event of Loss occurs with respect to the Airframe of the Aircraft.

     12:3 EVENT OF LOSS WITH RESPECT TO THE AIRFRAME. Upon the occurrence of an
Event of Loss with respect to the Airframe, or the Airframe and the Engines or
engines or Propellers or propellers then installed on the Airframe, Sublessee
shall forthwith (and; in any event, within three days after such occurrence)
give Sublessor, Guarantor, Lessor, and until delivery of the Release Notice,
Lender, written notice of such Event of Loss, and on or prior to the earlier of
(i) the ninetieth (90th) day following the day of occurrence of such Event of
Loss and (ii) the date of receipt of insurance payments in respect of such
occurrence, Sublessee shall pay:

          (1) to Lender (or, after delivery of the Release Notice, Lessor) the
sum of (A) the Stipulated Loss Value for the Aircraft as set forth in the
Stipulated Loss Value Table computed using the Base Rent Payment Date
immediately preceding the date on which such gent of Loss occurred (or, if such
Event of Loss occurred on a Base Rent Payment Date, computed using such Base
Rent Payment Date or, if such Event of Loss occurs before the First Base Rent
Payment Date, computed using the Delivery Date), plus (B) interest on the amount
determined pursuant to clause (A) at an effective rate per annum equal to the
Base Rate computed for the actual number of days elapsed (on the basis of a 365
or 366 day year as the case may be) from the date of the Event of Loss to the
date of payment of such Stipulated Loss Value, including the date of the Event
of Loss but excluding the date of payment; and

          (2) to Sublessor, or to Lender or Lessor, as the case may be, in
accordance with SECTION 9.2 hereof, the sum of any Supplemental Rent otherwise
due and payable on or before such payment date.

                                       25

If all such Stipulated Loss values and all such other amounts, including,
without limitation, any unpaid or accrued Rent, are paid in full, (x) the
obligation of Sublessee to pay all succeeding payments of Base Rent after the
Event of Loss hereunder with respect to the Aircraft shall terminate on the Base
Rent Payment Date immediately preceding the date of such Event of Loss or as of
the Base Rent Payment Date if such Event of Loss occurs on the Base Rent Payment
Date, and (y) provided that if (or when) no Default or Event of Default exists,
Sublessor will transfer or cause to be transferred to Sublessee, Lessor's title
to the Aircraft, including the Engines and Propellers or a number of engines and
propellers equal to the number of engines and propellers (which are not Engines
and Propellers) installed on the Aircraft at the time such Event of Loss
occurred, free and clear of Lessor Liens, Sublessor Liens and Lender Liens,
including the Lien of the Loan Agreement, and Sublessee shall be subrogated to
all claims, if any, of Sublessor or Lessor, as the case may be, against third
parties for damage to or loss of the Aircraft subject to such Event of Loss
(other than against insurers under insurance policies paid for by Sublessor,
Lessor, Lender or any Bank). Such transfer to Sublessee shall not affect or
limit in any way any obligations of Sublessee hereunder unless specifically
discharged by such payment of Stipulated Loss Value and Rent.

          12.4 EVENT OF LOSS WITH RESPECT TO AN ENGINE OR PROPELLER. Upon the
occurrence of an Event of Loss with respect to an Engine or Propeller in any
case where the provisions of SECTION 12.3 are not applicable, Sublessee shall
give Sublessor, Lessor, and until delivery of the Release Notice, Lender, prompt
written notice thereof and shall, within thirty (30) days after the occurrence
of such Event of Loss, duly convey to Lessor, as replacement for the Engine or
Propeller with respect to which such Event of Loss occurred, title to another
engine or propeller of the same or improved make, model and manufacturer (or
engine or propeller of at least the equivalent utility, value and remaining
useful life and suitable for installation and use on the Airframe) free and
clear of all Liens whatsoever (except Permitted Liens) and having a value,
remaining useful life and utility at least equal to, and being in as good
operating condition as, the Engine or propeller with respect to which such Event
of Loss occurred, but in all events in at least as good condition and repair as
required by the terms hereof immediately prior to the occurrence of such Event
of Loss and of the same or improved make, model and manufacturer as any other
Engine or Propeller, as applicable; PROVIDED, HOWEVER, that if Sublessee does
not then have reasonably available a Replacement Engine or Replacement
Propeller, as the case may be, conforming to the requirements set forth in this
SECTION 12.4, then Sublessee shall (x) within ninety (90) days after the
occurrence of such Event of Loss, either (i) notify Sublessor, Lessor and Lender
that Sublessee has made arrangements (which arrangements shall be reasonably
satisfactory to Sublessor, Lessor and Lender) to obtain a Replacement Engine or
Replacement Propeller, as the case may be,

                                       26
<Page>

conforming to the requirements of this SECTION 12.4 and shall obtain such
Replacement Engine or Replacement Propeller within ninety (90) days after
Sublessee shall have notified Sublessor and Lessor of such arrangements, or (ii)
place an order for a Replacement Engine or Replacement Propeller conforming to
the requirements of this SECTION 12.4, from the manufacturer of such Replacement
Engine or Replacement Propeller, PROVIDED, that if Sublessee obtains a
Replacement Engine or Replacement Propeller conforming to the requirements of
this SECTION 12.4 from another Person prior to the delivery of the Replacement
Engine or Replacement Propeller ordered from the manufacturer thereof, Sublessee
may use the Replacement Engine or Replacement Propeller obtained from such
Person in lieu of the Replacement Engine or Replacement Propeller ordered from
the manufacturer, and (y) promptly upon obtaining such Replacement Engine or
Replacement Propeller from the manufacturer or other Person, duly convey to
Lessor, as replacement for the Engine or Replacement Propeller with respect to
which such Event of Loss occurred, title to such Replacement Engine or
Replacement Propeller (free and clear of all Liens whatsoever (except Permitted
Liens)). In such case, Sublessee, at its own expense, will prior to or at the
time of any such conveyance (i) furnish to Lessor a warranty (as to title) bill
of sale, in form and substance reasonably satisfactory to Lessor, with respect
to such Replacement Engine or Replacement Propeller, (ii) cooperate in the
execution and delivery of a supplement hereto, in form and substance
satisfactory to Sublessor and Lessor, subjecting such Replacement Engine or
Replacement Propeller to this Sublease, to be duly executed by Sublessee and
recorded pursuant to the Transportation Code, (iii) furnish or cause to be
furnished to Sublessor, Lessor, and, until delivery of the Release Notice,
Lender, such evidence of Sublessee's (or other party's) title to such
Replacement Engine or Replacement Propeller (including, if requested, an opinion
of Sublessee's (or other party's) counsel and of compliance with the insurance
provisions of SECTION 13 with respect to such Replacement Engine or Replacement
Propeller as Lessor, Sublessor or Lender may reasonably request, and with an
opinion of Sublessee's (or other party's) counsel to the effect that title to
such Replacement Engine or Replacement Propeller, has been duly conveyed to
Lessor free and clear of all Liens whatsoever (except any Lessor Liens,
Sublessor Liens, Lender Liens and the Lien of Loan Agreement) and is duly
subleased hereunder (which legal opinions may contain qualifications and
statements of reliance reasonably satisfactory to Lessor, Sublessor and Lender),
(iv) furnish Sublessor a certificate signed by a duly authorized financial
officer or executive of Sublessee certifying that, upon consummation of such
replacement, no Default or Event of Default will exist hereunder; (v) furnish
such documents and evidence as Sublessor, Lessor or Lender, respectively, or
their respective counsel may reasonably request in order to establish the
consummation of the transactions contemplated by this SECTION 12.4, the taking
of all corporate proceedings in connection therewith and compliance with the
conditions set forth in this SECTION 12.4, in

                                       27
<Page>

each case in form and substance satisfactory to such party, (vi) file and record
such Uniform Commercial Code financing statements covering such Replacement
Engine or Replacement Propeller as may be reasonably requested by Sublessor,
Lessor and Lender, respectively, (vii) assign or cause to be assigned to Lessor
all existing warranties as of the date of transfer to the extent such warranties
are freely assignable, with respect to such Replacement Engine or Replacement
Propeller, subject to Sublessee's right to exercise these rights, so long as no
Event of Default has occurred, and (viii) take such other action as Sublessor,
Lessor or Lender may reasonably request in order that such Replacement Engine or
Replacement Propeller be duly and properly subject to the Lease and leased
thereunder; the Sublease and subleased hereunder, and the Lien of the Loan
Agreement, to the same extent as the Engine or Propeller replaced thereby. Upon
full compliance by Sublessee with the terms of this SECTION 12.4, Sublessor will
cause the appropriate party to transfer to Sublessee, at Sublessee's expense (i)
title to the Engine or Propeller with respect to which such Event of Loss
occurred and (ii) all claims for damage to such Engine or Propeller, if any,
against third Persons (other than against insurers under insurance policies paid
for by Sublessor, Lessor, Lender or any Bank) arising from the Event of Loss;
and Sublessor shall at Sublessee's expense, cause Lessor to execute and deliver
appropriate, bills of sale confirming such transfer. Any such transfer of title
shall be on an "AS-IS" and "WHERE-IS" basis without recourse or warranty,
express or implied except that such Engine or Propeller is free and clear of all
Lessor Liens, Lender Liens and Sublessor Liens, and shall release such Engine or
Propeller from the Lien of the Loan Agreement. Sublessee shall be subrogated to
all claims of Sublessor or Lessor, if any, against third parties (other than
insurers under insurance policies paid for by Sublessor, Lessor, Lender or any
Bank) for damage to or loss of the Engine or Propeller being replaced. For all
purposes hereof, each such Replacement Engine or Replacement Propeller shall be
deemed part of the property subleased hereunder, shall be deemed an "Engine" or
"Propeller" as defined herein and shall be deemed part of the Aircraft to the
same extent as the Engine or Propeller replaced thereby. An Event of Loss
covered by this SECTION 12.4 shall not result in any reduction in Base Rent.

          12.5 APPLICATION OF PAYMENTS FROM GOVERNMENTAL AUTHORITIES OR OTHERS.
Any payments (other than insurance proceeds the application of which is provided
for in SECTION 13) received at any time by Lessor, Sublessor or Sublessee from
any Governmental Body or other person with respect to an Event of Loss, to the
extent of the then applicable Stipulated Loss Value set forth in the Stipulated
Loss Value Table whether resulting from the condemnation, confiscation, theft or
seizure of, or requisition of title to or use of, the Airframe, or any Engine or
Propeller (other than a requisition for use by the United States Government not
constituting an Event of Loss), or otherwise, if paid to Sublessee shall be
immediately paid over to Lender, until delivery of the

                                       28
<Page>

Release Notice, and thereafter to Lessor, PROVIDED that Sublessee will endeavor
to have such payment made directly to Lender, until delivery of the Release
Notice, and in any event, such payment will be applied as follows:

          (i) if any such payments are received with respect to the Airframe,
or the Airframe and the Engines or engines, Propellers or propellers then
installed on the Airframe, so much of such payments as shall not exceed the
Stipulated Loss value required to be paid by Sublessee pursuant to SECTION 12.3
shall be applied in reduction of Sublessee's obligation to pay such Stipulated
Loss Value, if not already paid by Sublessee, or, if already paid by Sublessee,
shall be applied to reimburse Sublessee for its payment of such Stipulated Loss
Value, and the balance, if any, of such payments remaining thereafter will,
after Sublessee has paid all other Rent due and owing, be paid to the order of
Sublessor if received from a Governmental Body as a result of a requisition of
title to the Airframe or any Engine or Propeller, or from a Governmental Body
other than the United States Government with respect to a requisition of use of
the Airframe or any Engine or Propeller, and otherwise to Sublessee; and

          (ii) if such payment is received with respect to an Engine or
Propeller under the circumstances contemplated by SECTION 12.4, all such
payments shall be paid over to Sublessee, PROVIDED, Sublessee has fully
performed the terms of this SECTION 12 with respect to the Event of Loss for
which such payments are made, and FURTHER PROVIDED, no Default or Event of
Default exists and such payments shall be applied (if not earlier paid to
Sublessee) to the purchase price of such Replacement Engine or Propeller at
delivery thereof to Lessor under SECTION 12.4.

          12.6 REQUISITION FOR USE BY UNITED STATES GOVERNMENT WITH RESPECT
TO THE AIRFRAME AND ANY ENGINE OR PROPELLER INSTALLED THEREON. If the United
States Government requisitions the use of the Airframe, or the Airframe and the
Engines or, engines and Propellers or propellers then installed on the Airframe,
during the Term, and such requisition does not constitute an Event of Loss, all
of Sublessee's obligations under this Sublease with respect to the Aircraft
shall continue to the same extent as if such requisition had not occurred. All
payments received by Sublessor or Sublessee from the United States Government
for the use of the Airframe and Engines or engines and Propellers or propellers
during the Term shall be paid over to, or retained by, Sublessee, PROVIDED no
Default or Event of Default exists. If the Airframe, or the Airframe and Engines
or engines and Propellers or propellers, are not scheduled to be returned by the
United States Government prior to the end of the Term, Sublessor, upon notice
given not less than thirty (30) days before the end of the Term, may elect that
an Event of Loss hereunder be deemed to have occurred on the last day of the
Term and Sublessee shall, upon expiration of the Term, pay the Stipulated Loss
Value with respect to the Aircraft on such

                                       29
<Page>

date. Upon receipt of payment of Stipulated Loss value and all Rent and other
amounts due and payable under the Sublease, Sublessor shall transfer or shall
cause to be transferred to Sublessee title to the Aircraft free of all Sublessor
Liens, Lessor Liens and Lender Liens, including the Lien of the Loan Agreement.
If Sublessor has elected to treat such requisition for use as an Event of Loss,
upon payment by the Sublessee of the Stipulated Loss value and all other Rent
due and owing, all payments received by Sublessor or Sublessee from the United
States Government for the use of the Airframe, Engines and Propellers after
expiration of the Term shall be paid over to, or retained by, Subleasee. If
after expiration of the Term, Sublessor has not elected to treat such
requisition for use as an Event of Loss, all payments received by Sublessor or
Sublessee from the United States Government for the use of the Aircraft before
the expiration of the Term, shall be paid to or retained by Sublessee, PROVIDED,
HOWEVER, upon the expiration of the Term, Sublessor shall give notice to
Sublessee stating that this Sublease shall terminate, expire and be canceled
upon such date of expiration and the provisions of SECTION 19 shall be deemed to
have been satisfied, and subject to the provisions of this Sublease relating to
the survival of any of Sublessee's obligations hereunder, this Sublease shall
terminate, expire and be cancelled, and upon such termination, expiration and
cancellation, all payments received by Sublessor, Sublessee or any other Person
from the United States Government for the use of the Aircraft after the
expiration of the Term shall be paid over or retained: by Sublessor. Sublessee
shall promptly notify Sublessor in writing of any such requisition. Upon any
such requisition for use, Sublessee agrees to use its best efforts to obtain
reimbursement from the United States Government to Sublessor for damages
suffered by Sublessor as a result of such requisition for use. Sublessee agrees
to notify Sublessor promptly in writing in advance of the time when any
negotiations between Sublessee and the United States Government with respect to
any such requisition shall commence and will consult with Sublessor regarding
methods or procedures that are most appropriate to effect recovery from the
United States Government for any damages suffered by Sublessor, Lessor, Lender
or any Bank, by reason of such requisition for use. This SECTION 12.6 shall not
be applicable to the Aircraft if an Event of Loss with respect to the Aircraft
has occurred, except in the case where Sublessor has declared an Event of Loss
to have occurred as a result of a United States Government requisition for use.

          12.7 REQUISITION FOR USE BY UNITED STATES GOVERNMENT OF AN ENGINE OR
PROPELLER IN A MANNER CONSTITUTING AN EVENT OF LOSS. If the United States
Government requisitions the use of any Engine or Propeller in a manner
constituting an Event of Loss, Sublessee shall replace the Engine or Propeller
hereunder by complying with the terms of SECTION 12.4, and any payments received
by Sublessor or Sublessee from the United States Government with respect to such
requisition shall be paid over to, or retained by, Sublessee, PROVIDED no
Default or Event of Default exists.

          12.8 APPLICATION OF PAYMENTS OTHER THAN FOR AN EVENT OF LOSS. Any
payments received at any time by Sublessor or Sublessee from any Governmental
Body, insurer (other than under insurance paid for by Sublessee) or other Person
with respect to loss or damage to or requisition for use of the Airframe, any
Engine or Propeller or any other Aircraft not constituting an Event of Loss and
not governed by SECTIONS 12.6 AND 12.7, shall be applied in payment for repairs
or for replacement property in accordance with SECTION 11 and any balance
remaining after compliance with such sections with respect to such damage or
loss shall be paid over to or retained by Sublessee if Sublessor receives from
Sublessee prior to making any such payment, certification from Sublessee that
the property so damaged or lost has been repaired or replaced in full and that
the costs of such repairs or replacement have been paid in full. If such repairs
or replacements are made pursuant to contracts requiring progress payments or
are made by Sublessee, such proceeds shall be paid over to Sublessee from time
to time upon appropriate certification by Sublessee.

          12.9 APPLICATION OF PAYMENTS DURING DEFAULT.  Any amount received by
Sublessor referred to in SECTIONS 12.5, 12.6, 12.7 OR 12.8 that is payable to
Sublessee shall not be paid to Sublessee if at the time of such payment a
Default or an Event of Default exists, but shall be held by Lender, or if the
Release Notice has been delivered, by Lessor or Sublessor as security for the
obligations of Sublessee under this Sublease and at such time as any such
Default or Event of Default is not continuing, such amount, unless theretofore
otherwise applied in exercise of Sublessor's remedies hereunder, shall be paid
to Sublessee.

violation by Sublessee or any other additional insured of any warranty,
declaration or condition contained in such policies, and if available at
commercially reasonable cost such coverages shall be provided otherwise than by
way of endorsement with Lloyd's Form AVN67A; PROVIDED HOWEVER, that with respect
to secretion, embezzlement or conversion by Sublessee, no coverage shall apply

provide that each liability policy shall operate as a separate policy with
respect to Sublessor, Lessor and each Additional Insured and each Covered Person
but nothing herein shall operate to increase the liability of the underwriters
as set forth in the policies beyond the amount for which the underwriters would
have been liable if only one person or interest had been included as an insured;

costs and expenses, as shall not exceed the Stipulated Loss value required to be
paid by Sublessee pursuant to SECTION 12.3 and any past-due Rent shall be
applied in reduction of Sublessee's obligation to pay such Stipulated Loss Value
and all such other amounts if not already paid by Sublessee, or, if already paid
by Sublessee and no Default or Event of Default exists hereunder, shall be
applied to reimburse Sublessee for its payment, of such Stipulated Loss value
and all such other amounts, and the balance, if any, of such insurance proceeds

paid to Sublessee, provided that Sublessee shall have fully performed its
obligations and complied with the terms of SECTION 12.4 hereof with respect to
the Event of Loss for which such insurance proceeds are paid, such payments
shall be applied to the purchase price of such Replacement Engine or Propeller
at delivery thereof to Lessor under SECTION 12.4;

          (iii) so long as no Event of Default shall have occurred and be
continuing, the proceeds of any insurance required to be maintained by Sublessee
hereunder with respect to any property damage to the Airframe, any Engine or
Propeller shall be applied in the manner described in SECTION 12.8 upon evidence
of completion of repairs, or if such repairs or replacements are made pursuant
to contracts requiring progress payments or are made by Sublessee, upon receipt
of Sublessee's certification referred to in SECTION 12.8, shall be paid directly
to Sublessee; and

          (iv) any amount referred to in CLAUSES (i) (ii) OR (iii) immediately
above that is payable to Sublessee shall not be paid to Sublessee if at the time
of such payment a Default or Event of Default exists, but shall be held by
Sublessor, as security for the obligations of Sublessee under this Sublease and
at such time as there is not continuing any such Default or Event of Default
such amount, unless theretofore otherwise applied in exercise of
Sublessor's remedies hereunder, shall be paid to Sublessee;

     (9) if the liability policies are on a "claims-made basis" and not on an
"occurrence basis", Sublessee shall continue to carry such liability policies
for an additional three (3) years after the expiration or termination of this
Sublease and shall cause Lessor,

                                       35

Sublessor and each Additional Insured and Covered Person (regardless of whether
or not the Sublease has expired or been terminated) to be named as additional
insureds; and

     (10) shall be endorsed to provide the foregoing coverages in the form of
the endorsements set forth in EXHIBIT B and other endorsements reasonably
satisfactory to Sublessor, Lessor and Lender.

          13.4 REPORTS, ETC. Sublessee will cause its insurance broker to
furnish Sublessor, Lessor, Lender and each Additional Insured or Loss Payee (i)
on the Delivery Date of the Aircraft, (ii) on the policy anniversary date
thereafter, and (iii) on the date a Replacement Engine or Replacement Propeller
is conveyed to Lessor pursuant to SECTION 12.4, a report, dated the day of its
delivery, signed by Sublessee's insurance broker, reasonably acceptable to
Sublessor, Lessor and Lender, describing in reasonable detail the insurance then
carried and maintained on the Aircraft, certifying that such insurance complies
with the terms hereof and that the terms of this SECTION 13 have been endorsed
on such policies, and stating the opinion of such broker that such insurance is

protection of the respective interests of Sublessor, Lessor, Lender and each
Additional insured or Loss. Payee and each Covered Person, and is usual for
corporations operating similar aircraft and similarly situated with the
Sublessee, PROVIDED, HOWEVER, such opinion shall not be deemed to be a guarantee
or other undertaking that such limits will be adequate under all circumstances.
Sublessee will advise and will cause its insurance broker to advise Sublessor,
Lessor, Lender and each Additional Insured or Loss Payee in writing promptly 'of
any default in the payment of any premium and of any other act or omission on
the part of Sublessee which might invalidate or reader unenforceable, in whole
or in part, any insurance on the Aircraft. Sublessee shall cause its insurance
broker to furnish to Sublessor, Lessor and each Additional insured or Loss Payee
on the Delivery Date or as soon as available thereafter but not later than
thirty (30) days after the Delivery Date, copies of any insurance certificates
required to be carried hereunder, and within fifteen (15) days of replacement
thereof, copies of such replacement insurance certificates, or with respect to
any Replacement Engine or Replacement Propeller, within fifteen (15) days of
replacement thereof, certificates evidencing the insurance required to be
carried hereunder. If Sublessee fails to maintain insurance as provided herein,
Sublessor, Lessor or any Additional insured or Loss payee may, at its option,
provide such insurance and in such event, Sublessee shall, upon demand,
reimburse Sublessor, Lessor or such Additional Insured or Loss Payee, as the
case may be, as Supplemental Rent, for the cost thereof.

          13.5 INSURANCE FOR OWN ACCOUNT. Nothing in this SECTION 13 shall limit
or prohibit Sublessor, Lessor and each

                                       36
<Page>

Additional Insured or Loss Payee and each Covered Person, from obtaining
insurance for its own account and any proceeds payable thereunder shall be
payable as provided in the insurance policy relating thereto; PROVIDED that no
such insurance may be obtained which would limit, replace, or otherwise
adversely affect the coverage of any insurance required to be obtained or
maintained pursuant to this SECTION 13.

SECTION 14.   INDEMNITY.

          14.1 Sublessee hereby assumes liability for, and shall indemnify,
protect, save and keep harmless each Indemnified Person, including, without
limitation, Sublessor, Lessor, Lender and Guarantor, from and against, any and
all liabilities, obligations, losses, damages, penalties, claims, actions,
suits, costs, and expenses, including legal fees and expenses, of whatsoever

out of (i) maintenance, overhaul, repair, acquisition, construction,
manufacture, installation, purchase, ownership, delivery, lease, sublease,
possession, rental, use, condition, operation, transportation, return, sale,
replacement, storage or disposition of the Aircraft or any part thereof
(including, without limitation, liabilities in any way relating to or arising
out of the latent or other defects, whether or not discoverable by Sublessee or
any other person, injury to persons or property, patent, trademark, or invention
rights, or strict liability in tort), or (ii) this Sublease or any of the other
Operative Documents to which Sublessee is a party or any of the transactions,
obligations and indemnities contemplated hereby or thereby, or any other
document or instrument hereafter required to be executed and delivered by
Sublessee pursuant to the terms hereof or thereof, or the enforcement against
Sublessee of any of the terms of this Sublease or any of the other Operative
Documents, or (iii) the enforcement of any agreement, restriction or legal
requirement applicable to Sublessee affecting the Aircraft or any part thereof
or the operation, maintenance, use or possession of the Aircraft or any part
thereof by Sublessee; PROVIDED, HOWEVER, that Sublessee shall not be required to
indemnify any Indemnified Person for (A) Liabilities resulting from the gross
negligence or willful misconduct of such Indemnified Person or a successor,
assignee, director, officer, agent or employee of such Indemnified Person
(unless such willful misconduct or gross negligence results from acts or
omissions of Sublessee on behalf of such Indemnified Person); (B) Liabilities in
respect of the Aircraft which arise from acts or events that occurred prior to
the Delivery Date or occurring after the earlier of (x) the return of the
Aircraft under this Sublease and compliance by Sublessee with all of the
provisions of SECTION 19, and (y) the expiration or earlier termination of this
Sublease under circumstances not requiring the return of the Aircraft, except in
the case of any such return, expiration or termination occurring in connection
with the exercise

                                       37
<Page>

of rights pursuant to SECTION 18; (C) Liabilities to the extent resulting from
the breach of any representation, warranty or covenant made by an Indemnified
Person herein or in any other Operative Document to which such Indemnified
Person is a party (unless such breach is the result of Sublessee's failure to
comply with the Sublessee Documents); (D) Liabilities resulting from any
violation by an Indemnified Person of Section 5 of the Securities Act of 1933,
as amended (or any comparable successor thereto), or otherwise arising out of
the transfer, after the date of this Sublease, of any Note or of the ownership
interest in the Aircraft not consented to by Sublessee; (E) Liabilities which
are or relate to an Imposition described in SECTION 15 of this Sublease except
to the extent provided therein, it being understood that all indemnities for
Impositions are covered by SECTION 15; (F) Liabilities resulting from a
voluntary disposition by Lessor or any Indemnified Person, as the case may be,
affecting in respect of or of all or any part of its interest in the Aircraft,
the Airframe, any Engine, any Propeller, any Part, any Operative Document, the
Collateral or any payment of Rent, including any Liability arising as a result
of acts of or claims against, or which secure the obligations of Sublessor,
Lessor or Lender (or Persons claiming through Sublessor, Lessor or Lender), but
excluding any other acts of such Persons in accordance with the terms of this
Sublease or any other Sub lessee Document; or (G) Liabilities to the extent
arising out of or resulting from the construction, manufacture, installation or
design of the Aircraft by the Manufacturer, including any breach by the
Manufacturer of patent, trademark or invention rights in connection with the
construction, manufacture, installation or design of the Aircraft.

          14.2 Sublessee shall be bound under this SECTION 14 irrespective of
whether such Indemnified Person shall also be indemnified with respect to such
Liabilities elsewhere under this Sublease or under any other Operative Document
or by any other Person, and any Indemnified Person may proceed directly against
Sublessee under this SECTION 14 without first resorting to any such other rights
of indemnification. With respect to any payment for indemnity hereunder, such
payment for indemnity shall include any amount necessary to hold each
Indemnified Person harmless on a net after-tax basis and taking into account any
tax benefit or detriment realized by such Indemnified Person as a result of such
payment from all taxes required to be paid by such Indemnified Person with
respect to such payment for indemnity under the laws of any Federal, state or
local government or taxing authority in the United States of America.

          14.3 Upon commencement of any proceeding (including the written threat
or written claim of any proceeding) against an indemnified Person involving any
one or more Liabilities for which indemnity is provided hereunder, such
Indemnified Person shall promptly, upon receiving written notice thereof, give
notice of such commencement to Sublessee, PROVIDED that, the failure by

                                       38
<Page>

Indemnified Person so to notify Sublessee shall not release Sublessee from any
of its obligations under this SECTION 14, unless such failure materially impairs
Sublessee's ability to participate in such proceeding, but any payment by
Sublessee to any Indemnified Person pursuant to this SECTION 14 shall not be
deemed to constitute a waiver or release of any right or remedy (including any
remedy of damages) Sublessee may have against such Indemnified Person if, solely
as a result of the failure by indemnified Person to give Sublessee notice in
accordance with the first sentence of this paragraph, Sublessee is unable to
contest the Liability or other liability indemnified against pursuant to this
SECTION 14. Sublessee shall be entitled (i) in any proceeding that involves
solely a claim for one or more Liabilities or other liabilities in respect to
which Sublessee has an indemnity obligation pursuant to this SECTION 14, to
exercise and defend all rights of such Indemnified Person (PROVIDED that
Sublessee furnishes such Indemnified Person with an opinion of counsel
reasonably satisfactory to such Indemnified Person to the effect that there
exists a meritorious basis for contesting such liabilities or other liabilities
unless (x) such proceedings will, in the opinion of counsel for such
Indemnified Person involve any reasonable possibility of the sale, forfeiture or
loss of the Aircraft or any Engine or Propeller or any part thereof, or (y) such
Liabilities or other liabilities, in the opinion of counsel for Lessor, have
a reasonable possibility of otherwise compromising or jeopardizing any
substantial interests of Lessor in and to the Aircraft or any interest
hereunder) or to require such Indemnified Person to assume responsibility
therefor and control thereof, (ii) in any proceeding involving a claim fox one
or more such Liabilities or the transactions contemplated by this Sublease and
the other Operative Documents, to require such Indemnified Person to assume
responsibility therefor and control thereof to the extent that any of the same
may be and is severed from such other claims (so long as, in the opinion of
counsel for the affected Indemnified Person, such severance and assumption of
responsibility and control by such Indemnified Person does not have reasonable
possibility of adversely affecting the resolution of such other claims), or
(iii) in any other case, to be consulted by such Indemnified Person with respect
to proceedings subject to the control of such indemnified Person.
Notwithstanding any of the foregoing, Sublessee shall not be entitled to require
Sublessor or any other Indemnified Person to assume responsibility for and
control of any judicial proceeding if (A) the Liabilities or other liabilities
involved are less than $100,000 in the aggregate, or such Liabilities are
covered by insurance or Sublessee is financially capable of paying such claim or
Liability or (B) an Event of Default hereunder exists. In the event Sublessor
or any other Indemnified Person does not contest a Liability in any judicial
proceeding, Sublessee shall have the right, to the extent permitted by law, to
contest, at its sole cost and expense, any such claim or Liability by
substituting itself for Sublessor or such Indemnified Person in any judicial
proceeding that involves solely a claim or liability for one or more

                                       39
<Page>

Liabilities or other liabilities in respect to which Sublessee has an indemnity
obligation pursuant to this SECTION 14. To the extent Sublessee is entitled to
defend any claim hereunder, the Indemnified Person with respect to such claim
may participate at its sole cost and expense.

          14.4 Each Indemnified Person claiming hereunder shall supply Sublessee
with such information as Sublessee shall reasonably request to defend or
participate in any proceeding to the extent permitted by this SECTION 14. Unless
an Event of Default has occurred and is continuing, such Indemnified Person
shall not enter into a settlement or other compromise or consent to a judgment
with respect to any Liability without the prior written consent of the
Sublessee, (which consent shall not be unreasonably withheld or delayed), unless
such Indemnified Person waives its right to be indemnified with respect to such
Liability under this SECTION 14.

          14.5 If an Indemnified Person shall obtain a repayment of any
Liabilities paid by Sublessee pursuant to this SECTION 14, such Indemnified
Person shall promptly pay to Sublessee the amount of such repayment, together
with any interest (other than interest for the period, if any; after such
Liability was paid by such Indemnified Person until such Liability was paid or
reimbursed by Sublessee) received by such Indemnified Person on account of such
repayment.

          14.6 Nothing in this SECTION14 or in SECTION 15 shall be deemed to
constitute a guarantee by Sublessee of the residual value of the Aircraft or of
the payment of the Notes.

          14.7 In the event Sublessee shall be obligated to indemnify any
Indemnified Person pursuant to this SECTION 14, Sublessee shall be subrogated to
the rights of the Indemnified Person in respect of the matter as to which the
 indemnity was paid.

          14.8 For purposes of this SECTION 14, "Indemnified Person" shall
include all corporations making a consolidated or combined return in which an
Indemnified Person is included and the agents, employees, servants, successors
and assigns of any thereof.

          14.9 The provisions of this SECTION 14 shall survive the expiration
or termination of this Sublease.

Section 15.   TAXES AGAINST LESSOR OR AIRCRAFT.

          15.1 Sublessee hereby assumes liability for and shall pay, indemnify,
protect, save and keep each Indemnified Person, including, without limitation,
Sublessor, Guarantor, Lessor and Lender, harmless on an after-tax basis from and
against, any and all fees, taxes (including, without limitation, income,
franchise, excise, sales, use, occupational, capital, value added, property

                                       40

and stamp taxes and taxes imposed in respect of items of tax preference),
levies, assessments, imposts, duties, charges or withholdings of any nature
whatsoever, together with any penalties, fines or interest thereon (all of the
foregoing being herein collectively called "Impositions") imposed against any
Indemnified Person, Sublessee or the Aircraft or any part thereof by any
federal, state or local government or taxing authority or by any foreign
governmental subdivision or other foreign taxing authority (i) upon or with
respect to the Aircraft or any part thereof or any interest in any thereof, (ii)
upon or with respect to the manufacture, acquisition, construction,
installation, purchase, delivery, ownership, lease, sublease, possession,
rental, use, operation, transportation, return, sale, replacement, storage,
repossession, maintenance, repair, abandonment, redelivery, modification,
rebuilding, importation, exportation or disposition (excluding any disposition
of the Aircraft which occurs after the expiration of the Term of this Sublease
unless such disposition results from the termination of this Sublease pursuant
to a default under SECTION 18 hereof) of the Aircraft or any part thereof, (iii)
upon or with respect to the rentals, receipts, earnings or gains arising from
the Aircraft or any part thereof or the income or proceeds with respect to the
Aircraft, including, without limitation, principal, interest and. other amounts
payable on the Notes, (iv) upon or with respect to this Sublease or any other
Operative Document including the performance of any of the transactions,
obligations or indemnities contemplated hereby or thereby, or the issuance,
acquisition or transfer of the Notes, or (v) with respect to liabilities arising
under the Tax Indemnity Agreement solely as a result of acts or omissions of
Sublessee; PROVIDED, HOWEVER, that notwithstanding anything in this Sublease,
the Tax Indemnity Agreement, the Lease or any other Operative Document to the
contrary, Sublessee shall have no obligation to pay or to hold Sublessor or any
other Indemnified Person harmless against any tax, claim or other Liability,
with respect to:

               15.1.1 Impositions which are based on, or measured by, the net
income of any Indemnified Person to the extent imposed by the United States of
America, including Impositions by the United States Federal Government expressly
in lieu of such taxes and any withholding taxes imposed by the United States
federal government in connection with such Impositions;

               15.1.2 Impositions which are based on, or measured by, the net
income of any Indemnified Person to the extent imposed by any foreign country,
state, city or municipality or by any political subdivision of such foreign
country, state, city or municipality or any similar franchise, net worth, right
of an Indemnified Person to exist, doing business, or employing capital tax, but
only to the extent that the amount of any such Imposition imposed by any such
taxing authority does not exceed the amount of Impositions to which such
Indemnified Person would have been subject if the Aircraft had not been used,
operated, stored or

                                       41
<Page>

maintained in that taxing authority's jurisdiction;

               15.1.3 Impositions which are imposed with respect to any period,
or with respect to any act or omission, which occurred or failed to occur prior
to the Delivery Date with respect to the Aircraft or occurring after the earlier
of (x) the return of the Aircraft under this Sublease and compliance by
Sublessee with all of the provisions of SECTION 19, and (y) the expiration
or earlier termination of this Sublease under circumstances not requiring the
return of the Aircraft, except in the case of any such return, expiration or
termination occurring in Connection with the exercise of rights pursuant to
SECTION 18;

               15.1.4 Impositions resulting from a voluntary transfer or other
voluntary disposition or any involuntary transfer or involuntary disposition by
any Indemnified Person of any interest in the Aircraft, the Lease, the Sublease,
the Notes or the Collateral, unless such transfer or other disposition occurs
(A) while a Sublease Event of Default exists, if such transfer or other
disposition is pursuant to the exercise of one of Sublessor's remedies under the
Sublease as a result of such Sublease Event of Default, (B) pursuant to or in
accordance with a transfer or other event with respect to which Stipulated Loss
Value is required to be paid, unless such Stipulated Loss Value is paid in full,
or (C) in the case of an involuntary transfer or involuntary disposition, as a
result of any acts, omissions or misrepresentations of Sublessee;

               15.1.5 Impositions imposed upon Sublessor or any other
Indemnified Person by virtue of such Indemnified Person's failure to file
proper and timely reports or returns or to pay any taxes when due, failure to
claim an applicable exemption or failure to register with any governmental
entity having jurisdiction over Impositions, unless any of the foregoing
failures results from any action or omission by Sublessee, including the failure
to provide such Indemnified Person or any other Person information in a proper
and timely manner or otherwise to take such actions as are required of Sublessee
hereunder with respect to such Impositions;

               15.1.6 Impositions payable by any Indemnified Person as a direct
and primary result of such Indemnified Person's gross negligence or willful
misconduct or a breach or inaccuracy of a material representation or warranty or
covenant made by such Indemnified Person in any Operative Document or any
document required to be delivered under any Operative Document;

               15.1.7 Impositions imposed upon an Indemnified Person to the
extent resulting from such Indemnified Person engaging in transactions other
than those contemplated by the Operative Documents; or

               15.1.8 Impositions in the nature of an intangible tax imposed by
the Federal, state or local government or taxing

                                       42
<Page>

authority in the United States or any foreign country, upon or with respect to
the value of the interest of the Lender in the Notes or the Loan Agreement, but
only to the extent that (i) such Person would have been subject to such tax in
the absence of the use, operation, storage or maintenance of the Aircraft in
such jurisdiction or Sublessee's presence therein, or (ii) such Imposition is
described in any other clause of this SECTION 15.1;

PROVIDED, that Sublessee agrees to pay any such Impositions referred to in the
foregoing clauses which are in substitution for or relieve Sublessee from any
Impositions or indemnity therefor which Sublessee would otherwise be obligated
to pay under the terms of this SECTION 15.

          15.2 With respect to any payment or indemnity under this SECTION 15,
such payment or indemnity shall include any amount necessary to hold each
Indemnified Person harmless on a net after-tax basis (taking into account any
tax benefit or detriment realized as a result of receipt of such payment) from
all taxes required to be paid by such Indemnified Person with respect to such
payment or indemnity under the laws of any Federal, state or local government or
taxing authority in the United States of America. In case any report or return
is required to be filed with respect to any obligation of Sublessee under this
SECTION 15 or arising out of this SECTION 15, Sublessee will either make such
report or return in such manner as will show the ownership of the Aircraft in
Lessor or will notify Sublessor or such other Indemnified Person of such
requirement and make such report or return in such manner as shall be
satisfactory to Sublessor or such other Indemnified Person.

          15.3 (a) Upon the commencement of any proceeding (including the
written claim or written threat of any proceeding) against any Indemnified
Person involving one or more Impositions, such Indemnified Person shall
promptly, upon receiving written notice thereof, give notice of such
commencement to Sublessee. If Sublessee so requests in writing within thirty
(30) days after receipt of such notice, such Indemnified Person shall exercise
on Sublessee's behalf or, upon Sublessee's request, permit Sublessee to exercise
any contest rights which such Indemnified Person may have PROVIDED, HOWEVER,
that in no event shall any Indemnified Person be required to exercise its
contest rights or shall Sublessee be permitted (except with such Indemnified
Person's sole consent) to contest or to continue to contest any Imposition for
which Sublessee is obligated pursuant to this SECTION 15, unless (s) no Default
or Event of Default hereunder has occurred and is continuing; (t) no amounts of
Rent are past due under this Sublease; (u) the amount of such claim, together
with all claims of a similar nature (both present and reasonably expected to be
asserted), are at least $50,000 in the aggregate; (v) Sublessee acknowledges its
liability to such Indemnified Person for an indemnity payment in accordance with
the provisions of this SECTION

                                       43
<Page>

15 as a result of such claim if and to the extent such Indemnified Person or
Sublessee, as the case may be, does not prevail in the contest of such claim;
(w) such indemnified Person receives from Sublessee (i) an indemnity
satisfactory to such Indemnified Person for any liability, expenses or loss
arising out of or relating to such contest and (ii) an opinion of tax counsel
selected by Sublessee and reasonably acceptable to the affected Indemnified
Person to the effect that a reasonable basis exists for contesting such claim,
which opinion shall be in form and substance reasonably satisfactory to such
Indemnified Person and furnished at Sublessee's sole expense; (x) Sublessee
agrees to pay any expenses that any Indemnified Person may incur in connection
with contesting such claim (including, without limitation, all out-of-pocket
costs, expenses, losses, reasonable legal and accounting fees, disbursements,
penalties, interest and additions to tax); (y) such Indemnified Person obtains
at Sublessee's cost an opinion of independent counsel selected by the Sublessee
and approved by the affected Indemnified Person (which approval shall not be
unreasonably withheld) to the effect that the action to be taken will not result
in any risk of sale, forfeiture or loss of, or the creation of any Lien (except
if Sublessee adequately bonds such Lien or otherwise makes provision to protect
the interests of all Indemnified Persons in a manner reasonably satisfactory to
each Indemnified Person) on, the Aircraft, or any part or portion thereof or any
interest therein or in any way interfere with the timely payment of Rent or any
amount of the Loans from time to time becoming due and payable; and (z) if such
contest is conducted in a manner requiring the payment of the claim, Sublessee
pays the amount required in order to contest the claim. Any Imposition imposed
on an Indemnified Person as a result of an advance by Sublessee of a tax payment
or other costs incurred by such Indemnified Person, pursuant to this paragraph
shall he indemnified under this SECTION 15 without regard to the exclusions in
SECTION 15.1.1 and 15.1.2. An Indemnified Person shall keep Sublessee reasonably
informed of and shall permit Sublessee to participate in any such proceedings
that Sublessee does not conduct itself. if such Indemnified Person obtains a
refund of all or any part of any Imposition Paid by Sublessee, such Indemnified
Person shall pay Sublessee, but not before Sublessee makes all payments
theretofore due such Indemnified Person pursuant to this SECTION 15 and any
other payments theretofore due under any of the Operative Documents, an amount,
which after taking into account all taxes saved by such Indemnified Person as a
result of the payment of such amount, shall be equal to the amount of such
refund net of reasonable expenses not previously reimbursed and Impositions
payable with respect to receipt thereof, including interest received
attributable thereto; PROVIDED, HOWEVER, that notwithstanding the foregoing
portions of this sentence, such Indemnified Person shall not be obligated to
make any payment to Sublessee pursuant to this sentence as long as a Default or
an Event of Default exists hereunder, but such payment shall be held by such
Indemnified Person as security for the obligations of

                                       44
<Page>

Sublessee under the Operative Documents, and at such time as such Default or
Event of Default is later cured, then such Indemnified Person shall make such
payments to Sublessee.

          (b) Notwithstanding anything contained in this SECTION 15.3 to the
contrary, an Indemnified Person shall not be required to exercise its contest
rights on Sublessee's behalf if the subject matter of any claim is of a
continuing nature and has previously been decided adversely (other than as a
result of a settlement) pursuant to the contest provisions of this SECTION 15,
unless there is a Change in Law (including, without limitation, amendments to
statutes or regulations, administrative rulings and court decisions) after such
claim has been so previously decided, and such Indemnified Person receives an
opinion, also addressed to Sublessee, of tax counsel selected by the Sublessee
and approved by such Indemnified Person (which approval shall not be
unreasonably withheld) and furnished at Sublessee's sole expense to the effect
that, as a result of such change, it is more likely than not that the position
which such Indemnified Person or Sublessee, as the case may be, had asserted in
such previous contest, would prevail.

          (c) If, in the course of exercising its contest rights on Sublessee's
behalf, an Indemnified Person learns that a taxing authority is willing to agree
to a settlement of a claim, such Indemnified Person shall notify Sublessee of
such settlement proposal. If the settlement proposal is acceptable to Sublessee,
Sublessee shall so notify such Indemnified Person and such Indemnified Person
shall agree to the settlement proposal; PROVIDED, HOWEVER, that an Indemnified
Person shall not be obligated to agree to the settlement proposal if such.
Indemnified Person releases Sublessee from any further obligations pursuant to
this SECTION 15 with respect to such claim and if such Indemnified Person agrees
that the amount of any indemnity payment determined under this SECTION 15 in
respect of such claim, which Sublessee shall be required to pay to such
Indemnified Person, shall not exceed the amount of such indemnity payment that
would have been required if such Indemnified Person had agreed to the settlement
proposal. If any such settlement proposal is acceptable to such Indemnified
Person but is unacceptable to Sublessee, Sublessee shall inform such Indemnified
Person of the amount for which Sublessee would be willing to settle such claim.
If such Indemnified Person accepts the settlement proposal, the amount of any
indemnity payment determined under this SECTION 15 in respect of such claim that
Sublessee shall be required to pay to such Indemnified Person shall not exceed
the amount for which Sublessee would have been willing to settle such claim.

          (d) Nothing contained in this SECTION 15 shall require any Indemnified
Person to exercise its contest rights or permit Sublessee to contest a claim
which would otherwise require any Indemnified Person to exercise its contest
rights if such Indemnified Person waives payment by Sublessee of any amount that

                                       45
<Page>

might otherwise be payable by Sublessee under this SECTION 15 and the Tax
Indemnity Agreement by way of indemnity in respect of such claim. In the event
of such waiver, such Indemnified Person shall promptly return any amounts
previously advanced by Sublessee pursuant to this SECTION 15.3, including,
without limitation, payment of the impositions which were the subject of the
claim and reimburse Sublessee for amounts previously paid to such Indemnified
Person in respect of expenses incurred in contesting such claim.

          15.4 Each Indemnified Person shall supply Sublessee with such
information as may be reasonably requested by Sublessee as, in the reasonable
opinion of counsel of such Indemnified Person, will enable Sublessee to
participate in or control and conduct any proceeding to the extent permitted by
this SECTION 15. In the event that an Indemnified Person enters into a
settlement or other compromise with respect to any Imposition without prior
written consent of Sublessee (which consent shall not be unreasonably withheld
or delayed), such Indemnified Person shall be deemed to have waived its right to
be indemnified with respect to such Imposition under this SECTION 15.

          15.5 If by reason of any Impositions paid or indemnified against by
Sublessee under this SECTION 15 or the Tax indemnity Agreement any Indemnified
Person thereafter shall realize, in its sole opinion, a tax benefit (whether by
means of a credit, deduction or otherwise) that results in a reduction in
Impositions, then such Indemnified Person shall, to the extent it can do so
without prejudice to the retention of the amount of such benefit, pay to
Sublessee the amount which (after adjustment for any further tax savings
realized by such Indemnified Person as a result of the payment thereof) such
Indemnified Person, in its reasonable business judgment, determines to equal the
amount of such reduction in Impositions (such Indemnified Person's payment of
such amount, absent manifest error, being conclusive evidence of the amount So
owing to Sublessee), EXCEPT that such Indemnified Person shall not be obligated
to make any payment pursuant to this sentence to the extent the amount of such
payment would exceed (x) the amount of all prior payments in respect of such
Impositions by Sublessee to such Indemnified Person pursuant to this SECTION 15,
less (y) the amount of all prior payments in respect of such Impositions by such
Indemnified Person to Sublessee pursuant to this SECTION 15.

          15.6 In the event Sublessee shall fail to make any payment or to do
any act as provided in this SECTION 15, then Sublessor, Lessor or Lender shall
have the right, but not the obligation, without notice to or demand upon
Sublessee, and without releasing Sublessee from any obligation in this
SECTION 15, to make or do the same, and to pay, purchase, contest or compromise
any encumbrance, charge or lien which in Sublessor's, Lessor's or Lender's
judgment, as the case may be, places Lessor's title to the Aircraft, Lender's
security interest in the Aircraft, Lessor's interest in the Aircraft,
Sublessor's interest in the Aircraft, or

                                       46
<Page>

Sublessee's possession of the Aircraft in jeopardy and in exercising any such
rights, incur any liability and expend whatever reasonable amounts Sublessor,
Lessor or Lender in their respective absolute discretion may deem necessary
therefor. All sums so incurred or expended by Sublessor, Lessor or Lender shall
be, without demand, immediately due and payable by Sublessee and shall bear
interest at the Base Rate or such lesser amount as may represent the maximum
rate permitted by Applicable Law.

          15.7 In the event Sublessee shall be obligated to indemnify any
Indemnified Person pursuant to this SECTION 15 or the Tax Indemnity Agreement,
Sublessee shall be subrogated to the rights of the Person indemnified in
respect of the matter as to which the indemnity was paid.

          15.8 For purposes of this SECTION 15, "Indemnified Person" shall
include all corporations making a consolidated or combined return in which an
Indemnified Person is included and the agents, employees, servants, successors
and assigns of any thereof.

          15.9 Sublessee shall furnish Sublessor within sixty (60) days after
the end of each calendar year included in the whole or in part of the Term; a
report with respect to the location of the Aircraft during such calendar year in
sufficient detail to enable Sublessor and Lessor to determine the portions of
its income and deductions with respect to the transaction contemplated by the
Operative Documents appropriately treated as attributable or allocable to
sources within and without the United States within the meaning of Section
861-863 of the Code. Also, during the Term hereof, Sublessee agrees to maintain
or cause to be maintained such reasonable and customary records, and provide or
cause to be provided such reasonable and customary information, as Lessor may
reasonably require from Sublessor to enable Lessor to fulfill any of its tax
filing obligations, including without limitation, copies of all log books. Upon
written request of Sublessor, Sublessee also will promptly and duly execute and
deliver or cause to be duly executed and delivered, to Lessor or cooperate in
filing with the appropriate governmental authority, such further reasonable and
customary documents and assurances and take such further reasonable and
customary action as Sublessor may from time to time reasonably request in order
more effectively to carry out the intent and purpose of this Sublease and to
protect Lessor's right to the anticipated income tax consequences contemplated
by the Operative Documents.

          15.10 The provisions of this SECTION 15 shall survive the expiration
or termination of this Sublease and the other Operative Documents.

Section 16. FURTHER ASSURANCES, RECORDATION, TITLE, REGISTRATION.

          Sublessee shall cooperate with Sublessor in connection

                                       47
<Page>

with the filing and recording of this Sublease and Sublease Supplements thereto,
including but not limited to Sublease Supplement No. 1, and any other document
reasonably requested by Sublessor, and the maintenance of the recordation
thereof under the Transportation Code and in such other public offices as may be
deemed necessary and appropriate by FAA Counsel or by Sublessor or Sublessor's
counsel in order to protect the rights and interests of Sublessor hereunder and
to perfect such rights and interests of Sublessor in and to this Sublease and
the Rents due and to become due hereunder and will not register nor permit the
registration of the Aircraft under the laws of any jurisdiction outside the
United States. Sublessee shall not do any act or take or direct any Person to
take any action which might cause the Aircraft to be ineligible for registration
under the Transportation Code. Sublessee shall, at its expense, cooperate and
assist in accomplishing all recording, registrations and filings of this
Sublease, and any of the Operative Documents and any mortgage, security
interest, waiver, license, permit or certificate incident thereto, required by
law or deemed reasonably necessary by Sublessor, Lessor or Lender to protect
their respective interests, in the Aircraft, and shall furnish Sublessor with
satisfactory evidence of each such recording, registration and filing, including
without limitation, evidence that continuation statements have been filed with
respect to all financing statements filed pursuant to this SECTION 16. Sublessee
shall from time to time do and perform such other acts and execute such other
and further instruments as may be required by law or reasonably be requested by
Sublessor, including such legal opinions as may reasonably be required by
Sublessor, to establish, maintain and protect Sublessor's rights and remedies
and to carry out the effect, intent and purpose of this Sublease.

Section 17. INSPECTION, REPORTS, AUDITS.

          17.1 Sublessor, Lessor and, until delivery of the Release Notice,
Lender, and their respective authorized representatives may inspect (subject to
Sublessee's reasonable requirements regarding security), at their own expense,
the Aircraft and the books and records of Sublessee with respect thereto, and
make copies and extracts therefrom, and may discuss Sublessee's affairs,
finances, and accounts relating to the Aircraft and Sublessee's operation, with
its officers, and Sublessee shall furnish to Sublessor statements accurate in
all material respects regarding the condition and state of repair of the
Aircraft, all upon such reasonable notice and at such reasonable times during
normal hours and as often as may be reasonably requested and all at the expense
of Person requesting the same. None of Sublessor, Guarantor, Lessor nor Lender
shall have any duty to make any such inspection or inquiry or incur any
liability or obligation by reason of not making any such inspection or inquiry.
Sublessee may condition any such inspection or inquiry upon the agreement of the
Person requesting inspection to maintain

                                       48
<Page>

the same standard of confidentiality with respect to information so obtained as
customarily applies to such Person's own confidential information.

and not revealed to any party without

<Page>

the prior written consent of Sublessee, except that Sublessor may disclose such
reports to Guarantor, Lessor and Lender if it obtains and delivers to Sublessee
the same agreement with respect to confidential treatment of such reports, all
in form and substance reasonably satisfactory to Sublessee.

<Page>

and, if capable of being cured and Sublessee is diligently proceeding to so
cure, such untruthfulness or incorrectness shall continue to be unremedied for a
period of fifteen (15) days after written notice thereof by Sublessor; PROVIDED,

default, and at any time thereafter, Sublessor may exercise, and Sublessee shall
comply with, any or all of the following rights and remedies with respect to all
or any part of the Aircraft:

               18.2.1 Cause Sublessee, upon the written demand of

or store, and Sublessee shall assemble and return promptly or store, all or such
part of the Aircraft as Sublessor may so demand, to Sublessor or its order in

all of the rights of the owner, lessor, lienor or secured party with respect to
such engine or propeller, by summary proceedings, by self-help, or otherwise.

provided are of the essence of this Sublease, and upon application to any court
of equity having jurisdiction in the premises, Sublessor shall be entitled to a
decree against Sublessee requiring specific performance of the covenants of
Sublessee so as to return and store the Aircraft as provided in this SECTION
18.2.1 and in SECTION 19.

               18.2.2 Proceed by appropriate court action, or actions, either at
law or in equity, to enforce performance by Sublessee of the applicable
covenants of this Sublease or to recover damages for the breach thereof, and it

remedy given to Sublessor in addition to, and not in lieu of, any other remedies
given to Sublessor under this Sublease other than those provided for in SECTION
18.2.5;

event Sublessee fails to promptly return the Aircraft, Sublessor may take or
cause to be taken by its agent or agents immediate possession of the Aircraft
without any liability to Sublessor to return any Rent theretofore paid hereunder
and free and clear of any claims of Sublessee whatsoever, and may remove the
same from the possession and use of the Sublessee, and for such purpose may
enter onto Sublessee's premises where the Aircraft may be located and may use
and employ in connection with such removal any supplies, services, means or
other facilities of Sublessee with or without process of law, and Sublessee
hereby expressly agrees and

                                       54
<Page>

consents to the foregoing;

               18.2.4 With or without taking possession thereof sell, at one or
more public or private sales, at such times and places, to such persons
(including Sublessor) and without notice, or otherwise dispose of, use, operate,
sublease or hold, all or any part of the Aircraft as Sublessor may decide, free
and clear of any rights of Sublessee, and without any duty to account to
Sublessee with respect to such action for any proceeds thereof (except to the

Sublessee liable for any installment of Rent due on or before the date of such
sale to the extent such Rent covers the period upto the date of such sale, or

Aircraft as Sublessor may determine, in each case free and clear or any rights,
of Sublessee except as hereinafter set forth in this SECTION 18 and without any
duty to account to Sublessee with respect to such action or inaction;

               18.2.5 In order to preserve for Sublessor the benefits intended
by the transactions contemplated by the Sublease and the Sublessee Documents,
recover from Sublessee as liquidated damages for loss of bargain and not as a
penalty, which Sublessor shall be deemed to have sustained by reason of
Sublessee's breach of this Sublease or any other Sublessee Document, and to that
end, Sublessor, at its option without prejudice to any other remedies to which
it may be entitled, may exercise any of the following remedies under either
clause (i), (ii) or (iii) below, but not under more than one of such clauses:

               (i) Whether or not Sublessor has exercised, or at any time
exercises, any of its rights under SECTIONS 18.2.1 or 18.2.4 above with respect
to all or any part of the Aircraft, Sublessor, by written notice to Sublessee
specifying a payment date, which shall be a Base Rent Payment Date not earlier
than ten (10) days from the date of such notice, in order to preserve for
Sublessor the benefits intended by the transactions contemplated by the Sublease
and the Sublessee Documents, shall demand that Sublessee pay to Sublessor, and

as liquidated damages for loss of bargain and not as a penalty (in lieu only of
Base Rent for the Aircraft due after the payment date specified in such notice),
any unpaid Rent for the Aircraft due on or prior to the payment date specified
in such notice, plus whichever of the following amounts Sublessor, in its sole
discretion, shall specify in such notice (together with interest, if any, at the
Overdue Rate on the amount of any such unpaid Rent and on such specified amount
from the respective due dates to and including the actual date of payment): (A)
an amount equal to the excess, if any, of (1) the Stipulated Loss Value for the

aggregate Fair Market Rental Value of the Aircraft, or part thereof for the
remainder of its economic useful life after such specified payment date, after
discounting such aggregate Fair Market Rental Value quarterly to present worth
as of such specified payment date at a rate of six (6%) per annum; or (B) an
amount equal to the excess, if any, of (1) the sum of the stipulated Loss Value

then due hereunder, Sublessor shall, or shall cause the appropriate party to,
convey forthwith to Sublessee by bill of sale all of its right, title and
interest in and to the Aircraft on an "AS-IS", "WHERE-IS" basis and without
recourse or warranty, except that the Aircraft shall be free and clear of Lessor
Liens, Sublessor Liens and Lender Liens, including the Lien of the Loan
Agreement, and with no obligation to deliver possession if the Aircraft has not
been returned to Sublessor in accordance with SECTION 18.2.1 above.

<Page>

               18.2.6 OTHER REMEDIES. In lieu of or in addition to (to the
extent not inconsistent with) any of the foregoing remedies, Sublessor may (i)
terminate this Sublease as to the Aircraft, (ii) proceed by appropriate court
action to enforce the terms hereof or to recover damages for the breach hereof
as provided in, SECTION 18.2.2, and (iii) exercise any other right or remedy
which may be available to it under Applicable Law.

               18.2.7 CONCERNING REMEDIES. In addition to the other obligations
of Sublessee under this SECTION 18, Sublessee shall be liable, except as
otherwise provided in this SECTION 18, and to the extent not paid pursuant to
the other provisions of this SECTION 18, for any and all unpaid Rent due
hereunder, after or during the exercise of any of the foregoing remedies, for
any and all Supplemental Rent due hereunder, and for all legal fees (including
the allocated time charges of internal counsel) and other reasonable costs and
expenses incurred by reason of the occurrence of any Event of Default, or the
exercise of Sublessor's remedies with respect thereto, including all reasonable
costs and expenses incurred in connection with repossession, transportation,
storage, maintenance and insurance of the Aircraft and in placing the Aircraft
in the condition and airworthiness required by SECTION 19. At any sale of the
Aircraft or any part thereof pursuant to this SECTION 18, Lender, Lessor or
Sublessor may bid cash or the unpaid balance of any or all Loans (including all
other amounts secured by the Loan Agreement) or any combination thereof, for the
purchase of such property. Except as otherwise expressly provided above, no
remedy referred to in this SECTION 18 is intended to be exclusive, but each
shall be cumulative and in addition to any other remedy referred to above or
otherwise available to Sublessor at law or in equity, and the exercise or
beginning of exercise of any one or more of such remedies shall not be deemed an
election of such remedies and shall not preclude the simultaneous or later
exercise by Sublessor of any or all of such other remedies.

               18.2.8 WAIVERS. TO THE FULL EXTENT THAT SUBLESSEE AND SUBLESSOR
MAY LAWFULLY AGREE, SUBLESSEE AND SUBLESSOR HEREBY WAIVE THE BENEFIT OF ANY
PROVISION OF LAW NOW OR HEREAFTER IN EFFECT WHICH RENDERS ANY PROVISION HEREOF
PROHIBITED OR UNENFORCEABLE IN ANY RESPECT. NO EXPRESS OR IMPLIED WAIVER BY
SUBLESSOR OR SUBLESSEE OF ANY EVENT OF DEFAULT SHALL IN ANY WAY BE, OR BE
CONSTRUED TO BE, A WAIVER OF ANY FUTURE OR SUBSEQUENT EVENT OF DEFAULT.

          18.3 Whenever a determination of Fair Market Sale Value or Fair Market
Rental value is required by any provision of this Sublease, Sublessor shall
appoint a recognized independent aircraft appraiser selected by Sublessor to
determine the Fair Market Sale Value or Fair Market Rental Value of the Aircraft
and shall advise Sublessee of such appointment in its notice that Sublessor has
exercised its rights and remedies in accordance with this Sublease. Within
fifteen (15) days after receipt of such written notice from

                                       57
<Page>

Sublessor, Sublessee shall deliver to Sublessor a written notice appointing a
recognized independent aircraft appraiser selected by Sublessee to determine the
Fair Market Sale Value or Fair Market Rental Value of the Aircraft. If Sublessee
fails or refuses to appoint, for any reason whatsoever, an appraiser to
determine the Fair Market Sale Value or Fair Market Rental value of the Aircraft
within fifteen (15) days after receipt of written notice from Sublessor advising
Sublessee of the appointment of an appraiser by Sublessor, the decision of the
appraiser appointed by Sublessor as to the Fair Market Sale Value or Fair
Market Rental Value of the Aircraft shall in all cases be binding and conclusive
on Sublessor and Sublessee. The appraisers appointed by Sublessor and Sublessee
pursuant to this SECTION 18.3 shall meet promptly to determine the Fair Market
Sale Value or Fair Market Rental Value of the Aircraft. If within fifteen (15)
days after Sublessee selects its appraiser the two appraisers selected by
Sublessor and Sublessee, respectively, are unable to agree on the Fair
Market Sale Value or Fair Market Rental Value of the Aircraft, a third
recognized independent aircraft appraiser shall be chosen within fifteen (15)
days thereafter by the mutual agreement of such first two appraisers, or if such
first two appraisers fail to agree on the appointment of a third appraiser
within such fifteen (15) day period, such appointment shall be made by the
American Arbitration Association (or any organization which is successor
thereto). The decision of the appraisers so appointed and chosen shall be given
within fifteen (15) days after the selection of such, third appraiser. Any
decision in which any two appraisers so appointed and acting hereunder concur
shall in all cases be binding and conclusive on Sublessor and Sublessee and, in
the event that there are three appraisers and no two of such appraisers shall be
able to concur in the decision, then the simple arithmetic average of the
appraisals arrived at by the three (3) appraisers shall in all cases be binding
and conclusive on Sublessor and Sublessee. Sublessee shall pay the fees and
expenses of appraisal. The Fair Market Sale Value or Fair Market Rental Value of
the Aircraft shall be determined by the appraisers as of the date of premature
termination on the assumption (i) that the Aircraft will, on such date, be
equipped with the Airframe, the Engines and the Propellers, and that the
Airframe, the Engines and the Propellers will otherwise be in such condition as
would be required by this Sublease and (ii) if the time remaining on the
Airframe, the Engines, the Propellers, the components and/or the Parts on the
day of premature termination is less than the time required to be remaining
thereon in accordance with the provisions of SECTION 19 hereof and/or the
Airframe, the Engines, the Propellers, and/or the Parts thereof otherwise do not
meet the standards contemplated and required under SECTION 19 hereof or if the
condition of the Aircraft does not fully comply with the requirements of this
Sublease, that the Aircraft will fully comply with the requirements of this
Sublease.

          18.4 Sublessor may, at its election, waive any Event of

                                       58
<Page>

Default, and its consequences, and rescind and annul any such notice of
termination by notice to Sublessee in writing to that effect within sixty (60)
days after delivery of any such notice of termination, and thereupon the
respective rights of the parties shall be as they would have been if no Event
of Default had occurred and no such notice had been given. Notwithstanding the
provisions of this SECTION 18.4, it is expressly understood and agreed by
Sublessee that no express or implied waiver, recision or annulment by Sublessor
shall in any way be, or be construed to be, a waiver of any other past, future
or subsequent Event of Default, nor shall any such express or implied waiver,
recision, or annulment by Sublessor extend to or affect any other or subsequent
default or impair any rights or remedies consequent thereto.

          18.5 Each and every power and remedy herein specifically given to
Sublessor shall be in addition to every other power and remedy specifically so
given or now or hereafter existing at law or in equity, and each and every power
and remedy may be exercised from time to time or simultaneously as often as and
in such order as may be deemed expedient by Sublessor. Sublessor's acceptance of
any payment, whether partial or otherwise, after it shall become due hereunder
shall not be deemed to alter, affect or waive the obligations of Sublessee or
Sublessor's rights hereunder. All powers and remedies shall be cumulative and
the exercise of one shall not be deemed a waiver of the right to exercise any
other or others. No delay or omission of Sublessor in the exercise of any right
or remedy hereunder shall impair any power or remedy or shall be construed to be
a waiver of any Default or acquiescence therein. If any Event of Default shall
occur, Sublessor shall be entitled to recover reasonable costs and expenses,
including, without limitation, attorneys fees, as are incurred by Sublessor in
the enforcement of any right or privilege hereunder, plus interest thereon at
the Overdue Rate from the date such costs and expenses were expended or incurred
by Sublessor until paid by Sublessee

          18.6 To the fullest extent Sublessee may lawfully agree, Sublessee
hereby agrees in accordance with Section 1110 of the Bankruptcy Code as amended
from time to time (or any successor or superseding statute as amended) that
legal title to, and ownership by Lessor of, the Aircraft and each Engine and
Propeller, and any right of Sublessor, Lessor or Lender, or any party designated
by Sublessor under the Sublease, to take possession of the Aircraft, the Engines
and Propellers in compliance with the provision of this Sublease or the Lease
shall not be affected by and Sublessee waives any rights under Sections 362 or
363 of the Bankruptcy Code or any other analogous provisions of any succeeding
or superseding statute, as amended from time to time, or any similar provision,
insolvency, reorganization or similar law affecting the rights of creditors
generally which are inconsistent with Section 1110 of the Bankruptcy Code.
Sublessee further agrees that Lessor, Lender and each other assignee of Lessor
shall have the rights and benefits given to a lessor and/or a secured party
under Section 1110 of the

                                       59

Bankruptcy Code.

counsel) and shall take such other action as Sublessor may reasonably request in

Propeller replaced by a propeller pursuant to the preceding sentence without any
representation, warranty or recourse of any kind whatsoever, express or implied.

Sublessee will maintain in effect during such storage periods insurance covering

Sublessor. Notwithstanding the foregoing, Sublessee shall pay to Sublessor or
reimburse Sublessor for the cost to Sublessor of insuring the Aircraft during
any period of repair or overhaul subsequent to the termination of the Sublease
that is necessary to put the Aircraft in the condition required hereby. If any
required work, repairs or services should delay the return of the Aircraft to
Sublessor beyond the scheduled expiration or earlier termination of the Term
hereof, or prevents the use of the Aircraft thereafter, Sublessee shall continue
to pay Base Rent on a per diem basis and all other Rent, bear the risk of loss

the care required hereunder with respect to the Aircraft until such required
work, repair or servicing has been completed and, in the case of delay in
return, the Aircraft is returned to Sublessor as provided herein. Sublessee's
possession of the Aircraft during such period shall be solely as a bailee for
hire for Sublessor and not as Sublessee hereunder. During such period,

last day of the Term.

Sublessor such instruments of release and termination of this Sublease as to the
Aircraft, in form suitable for recording at the FAA Aircraft Registry and other

Section 20. ASSIGNMENT, SUB-SUBLEASE, SUBORDINATION.

          20.1 Except as otherwise provided herein, Sublessee will not and shall
have no power to, without the prior written consent of Sublessor, assign any of
its rights or obligations hereunder. The terms and provisions of this Sublease
shall be binding upon and inure to the benefit of Sublessor and Sublessee and
their respective successors and assigns and shall inure, to the extent expressly
herein provided, to the direct benefit of, and shall be enforceable, subject to
the terms of the Loan Agreement by Lender, subject to the terms of the Lease by
Lessor, and their respective successors and assigns.

          20.2 (a) Sublessee will not, without the prior written consent of
Sublessor (which will not be given without the prior written consent of Lessor
and Lender), except as otherwise provided in this Sublease, sub-sublease or
otherwise in any manner deliver, transfer or voluntarily relinquish possession,
or enter into any contract or arrangement obligating it to deliver, transfer or
relinquish possession of the Airframe or any Engine or Propeller, or install any
Engine or Propeller or permit any Engine or Propeller to be installed, on any
airframe other than the Airframe, or create a Lien not permitted under the terms
hereof.

          (b) Notwithstanding anything to the contrary contained in this
Sublease, Sublessee may merge or consolidate with any Affiliate of Sublessee or
sell, lease, or otherwise dispose of all or substantially all of its assets to
any Affiliate of Sublessee, PROVIDED (A) that the rights and powers of
Sublessor, Lessor and Lender shall not be adversely affected by such merger,
consolidation, sale, lease, or other disposition and that immediately after any
such transaction no Event of Default shall have occurred and be continuing, and,
(B) that any Affiliate of Sublessee which is to be the surviving or acquiring
corporation in

                                       67
<Page>

such transaction (i) shall be a corporation duly organized and validly existing
under the laws of the United States of America or a state thereof, or the
District of Columbia, and a "citizen of the United States of America" as defined
in Section 40102(a)(15) of the Transportation code, (ii) shall (unless
Sublessee is the surviving corporation), by agreement in writing which shall be
in form and substance satisfactory to Sublessor, expressly assume the due and
punctual payment of the Rent and other sums due and to become due under this
Sublease, and the due and punctual performance and observance of all the
covenants and provisions of this Sublease and each other Operative Document to
which Sublessee is a party, (iii) shall not have a net worth subsequent to such
action materially less than that of Sublessee prior to such action (taking into
account any corporations whose net worth is consolidated with such surviving
corporation), and (C) that such transaction shall not result in a material
adverse effect with respect to the assets, liabilities or operations of
Sublessee as consolidated in such survivor corporation.

          20.3 This Sublease and Sublessee's rights hereunder to the
possession, use and enjoyment of the Aircraft are subject and subordinate to all
of the rights of Lesser under the Lease including, without limitation, Lessor's
rights to repossession under the Lease and to avoid, cancel or terminate this
Sublease, for any reason upon such repossession or after an event of default by
the Lessee under the Lease (a "Repossession Event"), and Sublessee agrees upon a
Repossession Event to surrender possession of the Aircraft upon written demand
therefor by or on behalf of Lessor. Nothing in this section 20.3 shall be
construed to limit Sublessee's rights as against Sublessor hereunder if
Sublessee's right to possess the Aircraft hereunder is terminated because of a
Repossession Event. Sublessee has the right, following any actual or threatened
termination of this Sublease upon the occurrence of a Repossession Event (as
defined above), to inform Lessor of its desire to attorn to Lessor, and to
request that Lessor accept Sublessee as a direct lessee. Under the terms of any
such attornment, if accepted by Lessor, Sublessee will be required to perform
all of its obligations under this Sublease directly to and for the benefit of
Lessor and to also perform any obligations under the Lease not subsumed
hereunder. In no event shall any such attornment occur without the prior written
consent of Lessor, and Lessor may refuse such substitution for any reason in its
sole discretion.

          20.4 Sublessor covenants that, to the extent that any Lessor Liens,
Sublessor Liens or Lender Liens exist or interfere with Sublessee's peaceful and
quiet enjoyment and use of the Aircraft, Sublessor will use all reasonable
efforts, including the exercise of any rights it may have under any Operative
Document, to seek removal or discharge of such Liens. During the term of this
Sublease and so long as no Default or Event of Default has occurred and is
continuing hereunder, Sublessee shall be entitled to

                                       68
<Page>

exercise and enforce and assert at its sole expense all of the rights which the
Lessor has under any warranty or guaranty of any manufacturer with respect to
the Aircraft.

and (until at least March 1, 1998) AMR Leasing Corporation, AMR Corporation,
American Airlines, Inc., Simmons Airlines, Inc. and Executive Airlines, Inc. as

respect to each policy of liability insurance to which these endorsements are

the Loss Payee with respect to each policy of "all risks" insurance to which
these endorsements are attached. With respect to the interests of each
Additional Insured or Loss Payee in and with respect to the Aircraft as
defined in Section 2 of the Sublease (the "Subject Property") insured under each
policy by the insurers listed in the Schedule of Insurers attached as Annex 1
hereto (collectively, the "Company"), the Company hereby agrees that each "all
risks" policy includes the endorsements in Part A below; each liability policy
includes the endorsements in Part B below; and all policies include the
endorsements in Part C below:

A.   LOSS PAYABLE ENDORSEMENTS (HULL POLICY)

          This "all risks" insurance is endorsed with respect to the Subject
Property, (A) to name Lessor, Lender, Lessee and Guarantor as additional
insureds, as their respective interests may

                                        1
<Page>

appear ("Additional Insureds") and Lender, and following the

delivery of the Release Notice, Lessor, as loss payee, as their respective
interests may appear ("Loss Payee").

1.   Loss or damage, if any, to the Subject Property described in this policy to
     the extent of the Stipulated Loss Values set forth in the Stipulated Loss
     Value Table attached as Schedule 1 hereto shall be payable as follows:

     (i)  loss or damage with respect to the Subject Property which does not
          constitute an Event of Loss (as defined in the Sublease) shall be
          payable in United States Dollars solely to Lender (until Lender
          notifies Company in writing its lien is released, thereafter to
          Lessor); except loss or damage with respect to the Aircraft of
          $100,000.00 or less shall be payable to Named Insured, unless (A)
          prior to any loss or damage, Lender (or after Lender notifies Company
          in writing its lien is released, Lessor) notifies the Company that a
          Lease Event of Default exists, in which case such amounts shall be
          payable to Lender (or after Lender notifies Company in writing its
          lien is released, Lessor), or (B) prior to any loss or damage, Lessee
          notifies the Company that a Sublease Event of Default exists, in which
          case such amounts shall be payable to Lessee; and

     (ii) loss or damage with respect to the Subject Property described in this
          policy which constitutes an Event of Loss sha11 be payable by
          distributing (x) the amount set forth in Schedule 1 hereto ("SLV
          Amount") solely to Lender (until Lender notifies Company in writing
          its lien is released, thereafter to Lessor), and (y) any remaining
          amounts solely to Named Insured.

2.   Subject to paragraph 4 hereof, the insurance under this policy as to the
     interest only of the Loss Payee shall not be impaired in any way (i) by any
     action or inaction by Sublessee and shall insure the interest of the Loss
     Payee regardless of any breach or violation by Sublessee or any other
     additional insured of any warranty, declaration or condition contained in
     such policies, and if available at commercially reasonable cost such
     coverages shall be provided otherwise than by way of endorsement with
     Lloyd's Form AVN67A; PROVIDED HOWEVER, that with respect to secretion,
     embezzlement or conversion by Sublessee, no coverage shall
     apply to any Person which is a willful party to such secretion,
     embezzlement or conversion, or (ii) because of a subjection of the Aircraft
     to any condition, use or operation not permitted by the policy or (iii)
     because of any false statement with respect to the policy by Sublessee or
     its employees, agents or

                                        2
<Page>

     representatives, or any other Person except the Loss Payee (and then such
     Named Insured or its employees, agents or representatives, or any other
     person (except an Additional Insured, and then such policy will be
     impaired only as to such Person), whether occurring before or after the
     attachment of this endorsement, or whether before or after the loss.

3.   If the Named Insured fails to pay any premium or additional premium which
     shall be or become due under the terms of this policy, the Company agrees
     to give written notice to each Loss Payee of such nonpayment of premium and
     this policy shall continue in full force and effect if the Loss Payee when
     so notified in writing by the Company of the failure of the Named Insured
     to pay such premium, pays or causes to be paid the premium within thirty
     (30) days following receipt of the Company's written notice (seven (7)
     days, or such shorter period as may from time to time be the longest period
     obtainable in the industry, in the case of any war risk and allied perils
     coverage). If no Loss Payee pays said premium or additional premium, the
     rights of Lender, Lessor, Lessee or the Loss Payee under this Loss Payable
     Endorsement may be terminated by the Company thirty (30) days after receipt
     of said written notice by the Loss Payee (seven (7) days, or such shorter
     period as may from time to time be the longest period obtainable in the
     industry, in the case of any war risk and allied perils coverage).

4.   If the Company elects to cancel this policy in whole or in part for
     nonpayment of premium or for any other reason, the Company will forward a
     copy of the cancellation notice to the Loss Payee at its office specified
     hereinafter concurrently with the sending of notice to the Named Insured
     but in such case this policy shall continue in force for the benefit of the
     Loss Payee for thirty (30) days (seven (7) days, or such shorter period as
     may from time to time be the longest period obtainable in the industry, in
     the case of any war risk and allied perils coverage) after written notice
     of such cancellation is received by the Loss Payee by a copy sent by
     certified or registered mail, return receipt requested. In no event, as to
     the interest only of the Loss Payee, shall cancellation, lapse or adverse
     material change of any insurance under this policy be effected at the
     request of the Named Insured before thirty (30) days (seven (7) days, or
     such shorter period as may from time to time be the longest period
     obtainable in the industry, in the case of any war risk and allied perils
     coverage) after written notice of request for cancellation shall have been
     received by the Loss Payee by a copy sent by certified or registered mail,
     return receipt requested. If this policy is cancelled, the unearned premium
     shall be paid to the Loss Payee that has advanced such premium.

5.   The coverage provided herein is primary without contribution from any
     other insurance which might be available to the Loss Payee.

6.   Whenever the Company pays to Lender, Lessor, Lessee or Named Insured, any
     sum representing a total loss to the Subject Property insured under this
     policy, and claims that as to the Named Insured, no liability therefor
     exists, the Company, at its option, may pay to Lender, Lessor, Lessee
     or Named Insured, as the case may be, the Stipulated Loss Value (as such
     term is defined in the Sublease and the Schedules attached hereto, but in
     no event to exceed the Agreed Insured Value as stated in the policy), and
     the Company shall thereupon be subrogated to and receive a full assignment
     and transfer, without recourse, of said obligation and the security held as
     collateral therefor; but shall not exercise such subrogation and assignment
     right until each Additional Insured has recovered in full the amount of
     its respective claims against the Named Insured.

7.   The coverage granted under this policy shall continue in full force and
     effect as to the interest of the Loss Payee if the Loss Payee agrees to pay
     the premium therefor, for a period of thirty (30) days after expiration of
     said policy unless an acceptable policy in renewal thereof with loss
     thereunder payable in accordance with the terms of this Loss Payable
     Endorsement shall have been issued by an insurance company acceptable to
     Lender, Lessor and Lessee.

8.   Should this policy be continued for the term hereof for the benefit of the
     Loss Payee (with all incidents of ownership of the policy), Paragraphs 2, 6
     and 7 of Part A of this Loss Payable Endorsement shall no longer apply to
     the Loss Payee; PROVIDED, NEVERTHELESS, all privileges and endorsements
     which, by reason of the printed conditions of this policy, are or may be
     necessary to maintain the validity of the contract are hereby granted for
     a period of thirty (30) days, and all notices likewise required to be given
     to the Company by Named Insured are hereby waived for a period of thirty
     (30) days with the exception of requirements applying at the time of or
     subsequent to a loss.

9.   The Company waives any rights of subrogation against the Loss Payee, to the
     same extent as Sublessee has waived its right against the Loss Payee,
     except with respect to the gross negligence and/or willful misconduct of
     the Loss Payee; PROVIDED, that with respect to liability and property
     damage coverages hereunder such waiver shall not operate to prejudice the
     Company's rights of recourse against Saab Aircraft AB and/or Saab Aircraft
     of America, Inc., and/or any subsidiary thereof and General Electric
     Company and/or any subsidiary thereof, as manufacturers, repairers,
     suppliers or servicing

                                        4
<Page>

     agents (other than financial services) where such rights of recourse would
     have existed had such waiver not been given, and PROVIDED, FURTHER, that
     the exercise by the Company of rights of subrogation derived from rights
     retained by Named Insured shall not, in any way, delay payment of any claim
     that would otherwise be payable by the Company but far the existence of
     rights of subrogation derived from rights retained by Named Insured.

B.   LIABILITY POLICY ENDORSEMENTS

          This liability insurance policy is endorsed, with respect to the
Subject Property:

(A)  To name Lessor, Guarantor, Lender, Lessee and (until at least March 1,
     1998, AMR Leasing Corporation, AMR Corporation, American Airlines, Inc.,
     Simmons Airlines, Inc. and Executive Airlines, Inc.) as additional insureds
     as their respective interests may appear ("Additional Insureds") and shall
     cover (i) each of the shareholders of each Additional Insured, and (ii)
     officers, directors, employees, agents and representatives of each
     Additional Insured (with respect to each Additional Insured, collectively,
     "Covered Persons");

(B)  To provide that if this policy is cancelled for any reason whatsoever, or
     any substantial change is made in the coverage which affects the interest
     of the Additional Insureds and Covered Persons, or if such insurance is
     cancelled for nonpayment of premium or allowed to lapse, such cancellation,
     change or lapse shall not be effective as to the Additional Insureds and
     Covered Persons thirty (30) days (seven (7) days, or such shorter period as
     may from time to time be the longest period obtainable in the industry, in
     the case of war risk and allied perils coverage) after receipt by such
     Additional Insureds of written notice from the Company sent by certified or
     registered mail, return receipt requested, of such cancellation, change or
     lapse;

(C)  To provide that if the Named Insured fails to pay any premium or additional
     premium which shall be or become due under the terms of this policy, the
     Company agrees to give written notice to each Additional Insured of such
     nonpayment of premium and this policy shall continue in full force and
     effect if any one or more of the Additional Insureds when so notified in
     writing by the Company of the failure of the Named Insured to pay such
     premium, pays or causes to be paid the premium due within thirty (30) days
     following receipt of the Company's written notice. If no Additional Insured
     pays said premium or additional premium, the rights of Lender, Lessor,

                                        5
<Page>

     Lessee and other Additional Insureds and Covered Persons under this
     Liability Endorsement may be terminated by the Company thirty (30) days
     after receipt of said written notice by each Additional Insured;

(D)  To provide that the coverage granted under this policy shall continue in
     full force and effect as to the interest of each Additional Insured and
     Covered Person if any Additional Insured agrees to pay the premium
     therefor, for a period of thirty (30) days after expiration of said policy
     unless an acceptable policy in renewal thereof shall have been issued by
     an insurance company acceptable to Lender, Lessor and Lessee;

(E)  To provide that in respect of the interest of the Additional Insureds and
     Covered Persons, (i) this policy shall not be invalidated by any action of
     Named Insured and shall insure the respective interests of the Additional
     Insureds and Covered Persons named and covered under this Endorsement, as
     they appear, regardless of any breach or violation by Named Insured of any
     warranties, declarations or conditions contained in this policy or in the
     application therefor, if any, and (ii) severability of interest is
     included, PROVIDED nothing herein shall operate to increase the limits of
     liability and that coverage provided herein is primary without contribution
     from any other insurance which might be available to the Additional
     Insureds, and (iii) this insurance shall provide the same protection to
     each insured hereunder as would have been available had this policy been
     issued separately to each insured, except that in no event shall the
     Company's total liability exceed $100,000,000.00;

(F)  the Company waives any rights of subrogation against any Additional Insured
     and the Covered Persons of such Additional Insured to the same extent as
     Sublessee has waived its right against such Additional Insured and the
     Covered Persons of such Additional Insured, except with respect to the
     gross negligence and/or willful misconduct of such party; PROVIDED, that
     with respect to liability and property damage coverages hereunder such
     waiver shall not operate to prejudice the Company's rights of recourse
     against Saab Aircraft AB and/or Saab Aircraft of America, Inc., and/or any
     subsidiary thereof as manufacturers, repairers, suppliers or servicing
     agents (other, than financial services) where such rights of recourse would
     have existed had such waiver not been given, and PROVIDED, FURTHER, that
     the exercise by the Company of rights of subrogation derived from rights
     retained by Named Insured shall not, in any way, delay payment of any claim
     that would otherwise be payable by the company but for the existence of
     rights of subrogation derived from rights retained by Named Insured;
     and

(G)  to insure the Additional Insureds and the Covered Persons with

                                        6
<Page>

     respect to liability for matters which are the subject of Named Insured's
     obligations under the Sublease and Sublease Documents to the extent such
     insurance is provided under this policy; and to provide that such
     Additional Insureds and Covered Persons are warranted to have no
     operational interest.

        Nothing in these insurance Endorsements shall be deemed or construed to
be an agreement by the Company to insure the Manufacturer of the Aircraft, Saab
Aircraft AB, or the manufacturer of the engines, General Electric Company,
against claims arising out of product liability.
