Upon return of the Aircraft at the expiration or termination of this Lease, Lessee shall have caused all FAA Airworthiness Directives applicable to the Aircraft and all mandatory service bulletins from Manufacturer and the manufacturer of the Engines or any engine then installed on the Airframe (in compliance with Section 5.2) applicable to the Aircraft to have been complied with (except for any such FAA Airworthiness Directives and bulletins that permit compliance after the return date and would not, in the normal course of the Maintenance Program, be complied with on or prior to the return date). Lessee shall have treated the Aircraft, including without limitation, with respect to maintenance, additions and modifications, during the Term, similarly to all other Boeing 737-200 aircraft in its fleet. SALE AND LEASE AGREEMENT 13 At the request of Lessor delivered to Lessee not more than 30 days prior to the end of the Term, the Aircraft shall be check flown by Lessee (or any Permitted Sublessee) at Lessee's expense using qualified flight personnel, for not more than two hours, on a non-commercial flight, for the purpose of demonstrating to Lessor the satisfactory operation of the Aircraft and its equipment and systems; provided, however, that such check flight shall not interfere with the normal operation or maintenance of the Aircraft by, or the business of, Lessee (or any Permitted Sublessee). Up to five of Owner Participant's designees or representatives may participate in such flight as observers. The form of test flight procedure to be followed shall be in accordance with Lessee's normal test flight procedure, and the test flight may be a return delivery flight. The Aircraft shall be check flown only once pursuant to the provisions of this Section 5.3, unless further check flights are required in order to verify the correction of any discrepancy or malfunction detected in such first check flight, in which case a second check flight shall be performed in accordance with the procedures set forth herein solely in order to verify such correction. At redelivery of the Aircraft to Lessor hereunder, the following specific requirements shall be met by Lessee or, in lieu thereof, Lessee shall compensate Lessor therefor, as specifically provided for in this Section: 5.3.1 Airframe. (I) At least 40% of the time (or cycles, if applicable) shall remain before the next required performance of each structural work task card (the "Cards") (or the then equivalent under Lessee's Maintenance Program) (it being understood that, as used herein, "Cards" refers to the heaviest airframe check currently used under Lessee's Maintenance Program), and all Cards currently performed on a sampling basis under the Maintenance Program shall have been fully accomplished without regard to any sampling then permitted under the Maintenance Program, (II) Lessee shall have performed a complete "C" check or its equivalent (all phases) on the Airframe no more than 200 flight hours prior to its return to Lessor (and Lessee shall have corrected to the Lessor's reasonable satisfaction any deficiencies discovered during such check, and will not have deferred any maintenance discrepancies), and (III) Lessee shall have completed a complete "B" ("B1" and "B2") check immediately prior to redelivery; 5.3.2 Engines. Every ESV-1 Engine shall have no more than 4,000 hours or cycles since its last ESV-1. Each ESV-2 Engine shall have no more than 6,000 hours or cycles since its last ESV-2. No life limited component of an Engine shall have less than 3,000 hours or cycles remaining until its next required replacement. For the purposes of this Section, an ESV-1 Engine shall be an Engine or engine installed on the Airframe (in compliance with Section 5.2) whose last engine service visit (or the equivalent under the Maintenance Program) was an ESV-1, and an ESV-2 Engine shall be an Engine SALE AND LEASE AGREEMENT 14 or engine installed on the Airframe (in compliance with Section 5.2) whose last engine service visit (or the equivalent under the Maintenance Program) was an ESV-2; 5.3.3 Boroscope. The hot section of each Engine or engine installed on the Airframe (in compliance with Section 5.2) shall be inspected by boroscope at Lessee's expense and any defects which are outside the manufacturer's recommended limitations shall be corrected such that they are brought within such limitations; 5.3.4 Landing Gears. The landing gears shall have a minimum of 40% of the time remaining on each of the main and nose gears until the next scheduled shop visit or retirement, as the case may be; 5.3.5 APU. The auxiliary power unit shall not have more than 2,500 hours since the last "hot section" inspection; and 5.3.6 Other Components. All time-controlled components and life-limited components, other than engines, landing gear and auxiliary power units, shall have a minimum of 3,000 hours or twelve months (unless one-half of the allowable hours or months, as the case may be, permitted between shop visits or replacements is actually less than 3,000 hours or twelve months, in which case one-half of such allowable hours or months) remaining to the next scheduled shop visit or replacement. 5.4 Financial Adjustments. In the event that the conditions described in Sections 5.3.1 and 5.3.4 are not met, Lessee may elect, as to any or all of such conditions (a) to perform the work necessary to conform the Aircraft to the required condition or (b) to make a financial adjustment between Lessee and Lessor pursuant to this provision, provided that in no event shall the Aircraft or any landing gear be returned with less than 25% of the allowable hours or cycles, as appropriate, remaining between Cards (with respect to the Aircraft) or until the next scheduled shop visit (with respect to the landing gears): 5.4.1 Airframe, In the event that the Airframe is returned to Lessor with less than 40% but more than 25% of the allowable hours (or cycles, if applicable) between Cards as provided in Section 5.3.1, then Lessee shall pay to Lessor on the date the Term ends an amount determined by multiplying the difference between the actual number of hours (or cycles, if applicable) remaining to the next Cards and 40% of the allowable hours (or cycles, if applicable) between Cards times the cost to Lessee of having another Person perform such Cards. 5.4.2 [Intentionally omitted.] SALE AND LEASE AGREEMENT 15 5.4.3 Landing Gears, In the event that any of the landing gears is returned to Lessor with less than 40% but more than 25% of the cycles remaining until the next scheduled shop visit as provided in Section 5.3.4 above, then Lessee shall pay to Lessor on the date the term ends an amount computed by multiplying the difference between the actual number of cycles remaining to the next scheduled shop visit for such gear and 40% of the allowable cycles between shop visits times the cycle rate for the nose gear or the main gear, as the case may be. For purposes of this Section 5.4.3, the term "cycle rate" shall be deemed to be the cost that Lessee is paying to third parties at the time the Aircraft is returned under Section 5.3 for overhauling a nose gear or a main gear, as the case may be, divided by the number of cycles permissible between such overhauls under the Maintenance Program. At the end of the Term the Lessee shall furnish Lessor with an Officer's Certificate setting forth the hours and cycles remaining on the Engines or engines installed on the Airframe (in compliance with Section 5.2), the landing gear and the Airframe. 5.5 Manuals; Service Bulletins. Etc. Upon return of the Aircraft at the expiration or termination of this Lease, Lessee shall deliver or cause to be delivered to Lessor (in English) all logs, manuals, drawings and data and inspection, modification and overhaul records in respect of the Aircraft required to be maintained under applicable rules and regulations of the FAA, updated through the date of return. All "no-charge" service bulletin kits received by or on behalf of Lessee from Manufacturer, engine manufacturer or vendors for the Aircraft and Engines or engines and not incorporated therein shall be returned at no charge to Lessor as cargo on board the Aircraft at the time of its return. At the time the Aircraft is returned, Lessor shall have the option to purchase from Lessee, at Lessee's cost therefor, any "charge" service bulletin kits purchased by Lessee which have not been incorporated in the Aircraft. All such items shall thereupon become the property of Lessor. 5.6 Storage upon Return. Upon written request of Lessor received by Lessee at least 10 days prior to its return of the Aircraft at the expiration or termination of this Lease, Lessee will provide free parking facilities for the Aircraft for a period not exceeding 30 days following return thereof by Lessee at the location of return pursuant to Section 5.1; provided that such storage shall be at Lessor's risk and any expenses in connection with such storage (other than parking charges) shall be paid by Lessor, including the cost of any insurance therefor. 5.7 Failure to Return Aircraft or Engines. If Lessee shall, for any reason whatsoever, fail to return the Aircraft or any Engine at the time specified herein, the obligations of Lessee as provided in this Lease (including the obligation to pay Rent on the same basis as that applicable immediately prior to such failure) shall continue in effect with respect to the Aircraft or such Engine until the Aircraft or such Engine is returned SALE AND LEASE AGREEMENT 16 to Lessor; but this Section 5.7 shall not be construed as permitting Lessee to fail to meet its obligation to return the Aircraft or such Engine in accordance with the requirements of this Lease or constitute a waiver of a Lease Default or Lease Event of Default. 5.8 Aid in Disposition. Lessee agrees that, during the Term (and during any storage period) it will cooperate in all reasonable respects with any efforts of Lessor to lease or sell the Aircraft, including without limitation (subject to the provisions of Section 12) permitting potential lessees or purchasers to inspect the Aircraft and the records relating thereto. Section 6. Liens. Lessee will not directly or indirectly create, incur, assume or suffer to exist any Lien on or with respect to the Aircraft, the Airframe or any Engine, title thereto or any interest therein or in this Lease except: (a) the respective rights of the parties to the Operative Agreements; (b) the rights of others under agreements or arrangements to the extent expressly permitted by the terms of Sections 7.2 and 8.3; (c) Lessor Liens; (d) liens for taxes, assessments or other governmental charges either not yet due or being contested in good faith (and for the payment of which adequate reserves have been provided in accordance with generally accepted accounting principles) by appropriate proceedings so long as such proceedings do not involve any material danger of the sale, forfeiture, loss or loss of use of the Aircraft, the Airframe or any Engine or any interest therein; (e) materialmen's, mechanics', workers', repairers', employees' or other like Liens arising in the ordinary course of business for amounts the payment of which is either not yet due or not overdue for a period of more than 30 days or is being contested in good faith (and for the payment of which adequate reserves have been provided in accordance with generally accepted accounting principles) by appropriate proceedings so long as such Liens do not involve any material danger of the sale, forfeiture, loss or loss of use of the Aircraft, the Airframe or any Engine or any interest therein; (f) Liens arising out of any judgment or award against Lessee, unless the judgment secured shall not, within 45 days after entry thereof, have been discharged or vacated or execution thereof stayed pending appeal or shall not have been discharged, vacated or reversed within 45 days after the execution of such stay; and (g) any other Lien with respect to which Lessee shall have provided a bond or other security adequate in the reasonable judgment of Lessor. Lessee will promptly take (or cause to be taken) such action at its own expense as may be necessary duly to discharge any such Lien not excepted above if the same shall arise at any time. Section 7. Registration, Operation, Possession, Subleasing and Records. 7.1 Registration and Operation. 7.1.1 Registration. Lessee shall forthwith upon the delivery of the Aircraft hereunder cause the Aircraft to be duly registered and at all times thereafter to SALE AND LEASE AGREEMENT 17 remain duly registered in the name of Lessor with the FAA pursuant to and as permitted by the Act (it being understood that Lessee shall not be required to comply with this covenant to the extent that First Security Bank of Utah, National Association's or Owner Participant's failure to comply with its covenant set forth in Section 6.3.1.5 or Section 6.2.5, respectively, of the Participation Agreement with regard to its citizenship makes such compliance by Lessee impossible). 7.1.2 Nameplate. As soon as practicable after the Delivery Date, Lessee agrees to affix and thereafter to maintain in the cockpit of the Airframe adjacent to the airworthiness certificate and on each Engine a nameplate bearing the inscription "OWNED BY AND LEASED FROM FIRST SECURITY BANK OF UTAH, NATIONAL ASSOCIATION, AS OWNER TRUSTEE, OWNER AND LESSOR" and, so long as the Mortgage shall remain in effect, "SUBJECT TO A SECURITY INTEREST IN FAVOR OF PROGRESS CREDIT CORPORATION, MORTGAGEE" (such nameplate to be replaced, if necessary, with a nameplate reflecting the name of any successor Lessor or Lender, upon receipt of written notice from Lessor to such effect). Except as above provided, Lessee will not allow the name of any person, association or corporation to be placed on the Airframe or on any Engine as a designation that might be interpreted as a claim of ownership or Lien; provided that nothing herein contained shall prohibit Lessee (or any Permitted Sublessee) from placing its customary colors and insignia on the Airframe or any Engine or displaying information concerning the registration or manufacture of the Aircraft, the Airframe, any Engine or Part. 7.1.3 Compliance with Laws. Lessee agrees that it will not use or operate the Aircraft, the Airframe or any Engine in violation of any law or any rule, regulation or order of any government or governmental authority having jurisdiction (domestic or foreign) or in violation of any airworthiness certificate, license or registration relating to the Aircraft, the Airframe or any Engine issued by any such authority, except to the extent Lessee is contesting in good faith the validity or application of any such law, rule, regulation or order in any reasonable manner which does not materially adversely affect Lessor's interest in the Aircraft. 7.1.4 Insurance Requirements; Government Requisition; Indemnity. Lessee agrees not to operate, use or locate the Aircraft, the Airframe or any Engine, or permit any Permitted Sublessee to operate, use or locate the Aircraft, the Airframe or any Engine, (i) in any area excluded from coverage by any insurance required by the terms of Section 11, except in the case of a requisition by the Government where Lessee obtains indemnity (backed by the full faith and credit of the United States of America) in lieu of such insurance from the Government against the risks and in the amounts required by Section 11 covering such area, or (ii) in any area where maintenance of war-risk insurance is required by Section 11 unless fully covered by war-risk insurance satisfying the terms of Section 11, or unless the Aircraft, the Airframe or such Engine is operated or used under SALE AND LEASE AGREEMENT 18 contract with the Government under which contract the Government assumes liability (backed by the full faith and credit of the United States of America) in an amount not less than the amount of insurance otherwise required by Section 11 for any damage, loss, destruction or failure to return possession of the Aircraft, the Airframe or such Engine at the end of the term of such contract or for injury to persons or damage to property of others, or (iii) with respect to any sublease to a Permitted Foreign Air Carrier, in any area referred to in subclause (3)(iv) of Section 7.2. 7.2 Possession. Lessee will not, without the prior written consent of Lessor, sublease or otherwise in any manner deliver, transfer or relinquish possession of the Aircraft, the Airframe or any Engine or install any Engine, or permit any Engine to be installed, on any airframe other than the Airframe; provided, however, that, so long as no Lease Event of Default shall have occurred and be continuing, and so long as Lessee shall comply with the provisions of Section 11, and all FAA approvals required for such purposes have been obtained, Lessee may, without such prior written consent: 7.2.1 Interchange and Pooling. Subject or permit any Permitted Sublessee to subject (i) the Aircraft, Airframe or any Engine to normal interchange agreements customary in the United States domestic airline industry and entered into by Lessee or such Permitted Sublessee in the ordinary course of its business, and (ii) any Engine to pooling agreements or arrangements customary in the airline industry and entered into by Lessee or such Permitted Sublessee in the ordinary course of its business; but in either case (A) no transfer of the registration of the Airframe or any Engine shall be effected in connection therewith and the terms of this Lease and the Participation Agreement shall be observed, and (B) no such agreement or arrangement shall contemplate or require the transfer of title to the Aircraft, Airframe or any Engine and if Lessor's title to any Engine shall be divested under any such agreement or arrangement, such divestiture shall be deemed to be an Event of Loss with respect thereto and Lessee shall comply with Section 10.2 hereof; 7.2.2 Testing and Service. Deliver or permit any Permitted Sublessee to deliver possession of the Aircraft, Airframe or any Engine or Part, to the manufacturer thereof for testing or other similar purposes, or to any organization for service, repair, maintenance or overhaul work on the Aircraft, Airframe or any Engine or Part, or for alterations or modifications in or additions to the Aircraft, Airframe or any Engine to the extent required or permitted by the terms of Section 8.4; 7.2.3 Civil Reserve Air Fleet Program.

Install or permit any Permitted Sublessee to install an Engine on an airframe owned by Lessee or such Permitted Sublessee, as the case may be, free and clear of all Liens, except (A) Permitted Liens and those which apply only to the engines (other than Engines), appliances, parts, instruments, appurtenances, accessories, furnishings and other equipment (other than Parts) installed on such airframe (but not to the airframe as an entirety), (B) the rights of air carriers under normal interchange agreements which are customary in the airline industry and do not contemplate, permit or require the transfer of title to the airframe or engines installed thereon and (C) mortgage liens or other security interests, provided that (as regards this clause (C)) such mortgage liens or other security interests effectively provide that such Engine shall not become subject to the lien of such mortgage or security interest, notwithstanding the installation thereof on such airframe, unless and until Lessee shall become the owner of such Engine; 7.2.5 Installation of Engines on Other Airframes. Install or permit any Permitted Sublessee to install an Engine on an airframe leased to, or purchased by, Lessee or any Permitted Sublessee subject to a lease, conditional sale, or other security agreement, but only if (A) such airframe is free and clear of all Liens, except the rights of the parties to the lease, conditional sale, or other security agreement covering such airframe, or their successors or assigns, and except Liens of the type permitted by clauses (A) and (B) of Section 7.2.4, and (B) the lease, conditional sale, or other security agreement covering such airframe effectively provides that such Engine shall not become subject to the Lien thereof at any time while such Engine is subject to this Lease, notwithstanding the installation thereof on such airframe; 7.2.6 Pooling of Parts.

Lessee shall maintain, service, repair, overhaul, alter, modify, add to and test (or cause to be maintained, serviced, repaired, overhauled, altered, modified, added to and tested) the Aircraft, the Airframe and each Engine, and each other engine installed from time to time on the Airframe, in accordance with Lessee's FAA-approved maintenance program for the Aircraft, Airframe and Engines (the "Maintenance Program"), (i) so as to keep the Aircraft, the Airframe and each Engine in as good operating condition as on the Delivery Date, ordinary wear and tear excepted, (ii) in the same manner and with the same care as used by Lessee with similar aircraft owned or operated by Lessee, and (iii) so as to keep the Aircraft, the Airframe and each Engine in such condition as required to enable the FAA certificate of airworthiness for the Aircraft to be maintained in good standing at all times under the Act, except when all comparable Boeing Model 737-200 series aircraft registered in the United States of America have been grounded by the FAA other than as a result of actions taken or omitted to be taken by Lessee (or, if a sublease is then in effect, any Permitted Sublessee). SALE AND LEASE AGREEMENT 23 8.1.2 Compliance with Government Requirements. Lessee will comply with all service, inspection, maintenance, repair and overhaul regulations, directives and instructions which are made mandatory by the FAA or other Government authority upon United States operators of Boeing Model 737-200 series aircraft and Pratt & Whitney JT8D-9A engines and which require compliance during the Term and prior to return of the Aircraft under this Lease. 8.2 Replacement of Parts. Lessee, at its own cost and expense, will promptly replace (or cause to be replaced) all Parts which may from time to time be incorporated in the Aircraft, Airframe or any Engine and which may from time to time become worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for use for any reason whatsoever, except as otherwise provided in Section 8.4. In addition, Lessee may, at its own cost and expense, remove in the ordinary course of maintenance, service, repair, overhaul or testing any Parts, whether or not worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for use; provided, however, Lessee, except as otherwise provided in Section 8.4, at its own cost and expense, will replace such Parts as promptly as possible. All replacement Parts shall be free and clear of all Liens (except for Permitted Liens and except in the case of replacement property temporarily installed on an emergency basis) and shall be in as good operating condition as, and shall have a value and utility at least equal to, the Parts replaced assuming such replaced Parts were in the condition and repair required to be maintained by the terms hereof. All Parts at any time removed from the Aircraft, Airframe or any Engine shall remain the property of Lessor, no matter where located, until such time as such Parts shall be replaced by Parts which have been incorporated in the Aircraft, Airframe or such Engine and which meet the requirements for replacement Parts specified above. Immediately upon any replacement Part becoming incorporated in the Aircraft, Airframe or such Engine as above provided, without further act, (i) title to the replaced Part shall thereupon vest in Lessee free and clear of all rights of Lessor, and the replaced Part 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 except in the case of replacement property temporarily installed on an emergency basis), and (iii) such replacement Part shall become subject to this Lease and be deemed part of the Aircraft, Airframe or such Engine for all purposes hereof to the same extent as the Parts originally incorporated in such Aircraft, Airframe or Engine. 8.3 Pooling of Parts. Any Part removed from the Aircraft, Airframe or any Engine as provided in Section 8.2 may be subjected by Lessee (or a Permitted Sublessee) to a normal pooling arrangement customary in the airline industry entered into in the ordinary course of business of Lessee or such Permitted Sublessee, so long as a Part replacing such removed Part shall be incorporated in the Aircraft, Airframe or such Engine in accordance with Section 8.2 as promptly as practicable after the removal of such removed Part. In addition, any replacement Part when incorporated in the Aircraft, SALE AND LEASE AGREEMENT 24 Airframe or any Engine in accordance with Section 8.2 may be owned by any third party subject to such a normal pooling arrangement, so long as Lessee (or any Permitted Sublessee), at its own cost and expense, as promptly thereafter as practicable either (i) causes title to such replacement Part to vest in Lessor in accordance with Section 8.2 by Lessee (or any Permitted Sublessee) acquiring title thereto for the benefit of, and transferring such title to, Lessor free and clear of all Liens (except Permitted Liens), or (ii) replaces such replacement Part by incorporating in the Aircraft, Airframe or such Engine a further replacement Part owned by Lessee (or any Permitted Sublessee) free and clear of all Liens (except Permitted Liens) and by causing title to such further replacement Part to vest in Lessor in accordance with Section 8.2. 8.4 Alterations, Modifications and Additions. Lessee, at its own cost and expense, shall make (or cause to be made) such alterations and modifications in and additions to the Aircraft, Airframe and each Engine as may be required from time to time to meet the standards of the FAA or other governmental authority having jurisdiction and to maintain the FAA certificate of airworthiness for the Aircraft; provided, however, that Lessee may contest in good faith the validity or application of any such law, rule, regulation or order in any reasonable manner which does not materially adversely affect Lessor's interest in the Aircraft; and provided, further, that Lessee's failure to make (or cause to be made) any such alterations or modifications shall not constitute noncompliance with the requirements of this Section 8.4 or a breach of Lessee's undertaking hereunder for so long a period as may be necessary to remedy such failure, if such failure can be remedied, so long as during such period Lessee is using due diligence and reasonable efforts to remedy such failure. In addition, Lessee, at its own cost and expense, may, from time to time make (or cause to be made) such alterations and modifications in and additions to the Aircraft, Airframe or any Engine as Lessee may deem desirable in the proper conduct of its business, including, without limitation, removal of Parts which Lessee deems obsolete or no longer suitable or appropriate for use in the Aircraft, Airframe or such Engine; provided, however, that no such alteration, modification or addition shall, in Lessee's reasonable judgment, materially diminish the value or utility of the Aircraft, Airframe or such Engine, or materially impair the condition or airworthiness thereof, below the value, utility, condition and airworthiness thereof immediately prior to such alteration, modification or addition assuming the Aircraft, Airframe or such Engine was then of the value and utility and in the condition and airworthiness required to be maintained by the terms of this Lease. Title to all Parts incorporated in the Aircraft, Airframe or such Engine as the result of such alteration, modification or addition shall, without further act, vest in Lessor. Notwithstanding the foregoing sentence of this Section 8.4, so long as no Lease Event of Default or Lease Default shall have occurred and be continuing, Lessee may, at any time during the Term, remove any Part if (i) such Part is in addition to, and not in replacement of or substitution for, any Part originally incorporated (or required by the provisions of this Lease to be incorporated) in the Aircraft, Airframe or such Engine at the time of delivery thereof hereunder or any Part in replacement of or substitution for SALE AND LEASE AGREEMENT 25 any such Part, (ii) such Part is not required to be incorporated in the Aircraft, Airframe or such Engine pursuant to the terms of this Section 8, and (iii) such Part can be removed from the Aircraft, Airframe or such Engine without diminishing or impairing the value, utility, condition or airworthiness required to be maintained by the terms of this Lease which the Aircraft, Airframe or such Engine would have had at such time had such alteration, modification or addition not occurred. Upon the removal by Lessee of any Part as above provided, title thereto shall, without further act, vest in Lessee and such Part shall no longer be deemed part of the Aircraft, Airframe or such Engine from which it was removed. Any Part not removed by Lessee as above provided prior to the return of the Aircraft, Airframe or such Engine to Lessor hereunder shall remain the property of Lessor. Section 9. [Intentionally Omitted] Section 10. Loss, Destruction, Requisition, Etc. 10.1 Event of Loss with Respect to Aircraft. Upon the occurrence of an Event of Loss with respect to the Aircraft, Lessee shall forthwith (and in any event within 15 days after such occurrence) give Lessor and each Participant written notice of such Event of Loss. On or before the Business Day next preceding the earlier of (i) the 180th day following the date of the occurrence of such Event of Loss, or (ii) 15 days following the receipt of insurance proceeds with respect to such occurrence, Lessee shall pay to Lessor, in the manner and in funds of the type specified in Section 3.5, (A) the Stipulated Loss Value for the Aircraft, (B) all unpaid Basic Rent or Renewal Rent accrued through and including the date of payment of Stipulated Loss Value and (C) (without duplication) any other Rent which is due and payable through and including the date of such payment. Upon payment in full of Stipulated Loss Value and all such accrued Basic or Renewal Rent pursuant hereto, (A) the obligation of Lessee to pay Basic or Renewal Rent due after the date of such payment shall terminate (but Lessee shall remain liable for all payments of Supplemental Rent due through and including the date of such payment of Stipulated Loss Value), (B) the Term for the Aircraft shall end, and (C) Lessor will Transfer to Lessee the Aircraft. Upon compliance by Lessee with all of the terms of this Section 10.1, Lessee will be subrogated to all claims of Lessor, if any, against third parties for damage to or loss of such Airframe and Engines to the extent of the then insured value thereof. 10.2 Event of Loss with Respect to an Engine. 10.2.1 Event of Loss. Upon the occurrence of an Event of Loss with respect to an Engine under circumstances in which there has not occurred an Event of Loss with respect to the Airframe, Lessee shall give Lessor and each Participant prompt written notice (and in any event within 15 days after such occurrence) thereof and shall, SALE AND LEASE AGREEMENT 26 as promptly as possible and in any event within 60 days after the occurrence of such Event of Loss, convey or cause to be conveyed to Lessor, as replacement for the Engine with respect to which such Event of Loss occurred, title to a Replacement Engine free and clear of all Liens, other than Permitted Liens, and having a value and utility at least equal to, and being in as good operating condition as, the Engine with respect to which such Event of Loss occurred, assuming such Engine was of the value and utility and in the condition and repair required by the terms hereof immediately prior to the occurrence of such Event of Loss. 10.2.2 Conditions; Lessee's Obligations. Prior to or at the time of any such conveyance, Lessee will promptly: (a) furnish Lessor with a full warranty (as to title) bill of sale duly conveying to Lessor such Replacement Engine; (b) cooperate with any reasonable request of Lender to subject such Replacement Engine to the Lien of the Mortgage; and cause a Lease Supplement subjecting such Replacement Engine to this Lease, duly executed by Lessee, to be delivered to Lessor for execution and, upon execution, to be filed for recordation with the FAA pursuant to the Act; (c) furnish Lessor and Lender with such evidence of compliance with the insurance provisions of Section 11 hereof with respect to such Replacement Engine and the payment of all premiums then due with respect to such insurance, as Lessor or Lender may reasonably request; (d) furnish Lessor and Lender with an opinion or opinions of Lessee's counsel, in form, substance and scope reasonably satisfactory to Lessor and Lender, to the effect that, upon such conveyance, Lessor will acquire good title to such Replacement Engine free and clear of all Liens other than Permitted Liens (including Lender's interests), and that such Replacement Engine will be leased hereunder and will be subject to the Lien of the Mortgage to the same extent as the Engine replaced thereby and to such further effect as Lessor or Lender may reasonably request; (e) furnish Lessor and Lender with an Officer's Certificate certifying that, upon consummation of such replacement, no Lease Event of Default or Lease Default will exist hereunder; and (f) furnish such other certificates or documents (including appropriate UCC-3 amendments to the financing statements filed on or before the Delivery Date) as Lessor or any Participant may reasonably request to effect such replacement. SALE AND LEASE AGREEMENT 27 10.2.3 Recordation and Opinions. In the case of any Replacement Engine conveyed to Lessor under this Section 10.2, promptly upon the recordation of the Lease Supplement and any supplement or amendment to the Mortgage covering such Replacement Engine pursuant to the Act, Lessee will cause to be delivered to Lessor and Lender an opinion of William C. Boston & Associates or other FAA counsel satisfactory to Lessor as to the due recordation of such Lease Supplement and any such supplement or amendment to the Mortgage. 10.2.4 Conveyance; Replacement Engine. Upon compliance by Lessee with the terms of this Section 10.2, Lessor will Transfer to Lessee the Engine with respect to which such Event of Loss occurred, and Lessee will be subrogated to all claims of Lessor, if any, against third parties for damage to or loss of such Engine to the extent of the insured value thereof. 10.2.5 No Reduction of Rent. No Event of Loss with respect to an Engine under the circumstances contemplated by the terms of this Section 10.2 shall result in any changes of Basic Rent or Renewal Rent. 10.3 Application of Certain Payments. Any payments (other than insurance proceeds, the application of which is provided for in Section 11) received at any time by Lessor, Lessee or any Permitted Sublessee from any governmental authority or other Person with respect to any Event of Loss, will be applied as follows: 10.3.1 Replacement of Engine. If such payments are received with respect to an Engine that has been or is being replaced by Lessee pursuant to Section 10.2, so much of such payments remaining after reimbursement of Lessor and Owner Participant for costs and expenses shall be paid over to, or retained by, Lessee, provided Lessee shall have fully performed or, concurrently therewith, will fully perform the terms of Section 10.2 with respect to the Event of Loss for which such payments are made. 10.3.2 Nonreplacement. If such payments are received with respect to the Airframe and/or Engines that have not been and will not be replaced pursuant to Section 10.2, so much of such payments remaining after reimbursement of Lessor and Owner Participant for costs and expenses as shall not exceed the Stipulated Loss Value and other amounts required to be paid by Lessee hereunder shall be applied in reduction of Lessee's obligation to pay such Stipulated Loss Value and other amounts if not already paid by Lessee, or, if already paid by Lessee, shall be applied to reimburse Lessee for its payment of such Stipulated Loss Value and other amounts. The balance, if any, of such payment remaining thereafter shall be divided between Lessor and Lessee in proportion to their interests in the Aircraft. SALE AND LEASE AGREEMENT 28 10.4 Requisition of Aircraft for Use by Governmental Authorities. In the event of the requisition, unless and until such requisition becomes an Event of Loss, for use of the Airframe and the Engines or engines installed on such Airframe during the Term by any governmental authority, Lessee shall notify Lessor of such requisition, and, unless and until such requisition becomes an Event of Loss, all of Lessee's obligations under this Lease with respect to the Aircraft shall continue to the same extent as if such requisition had not occurred. All payments received by Lessor or Lessee from such governmental authority for the use of such Airframe and Engines or engines prior to the time such requisition becomes an Event of Loss shall be paid over to, or retained by, Lessee (or, if directed by Lessee, any Permitted Sublessee); and all payments received by Lessor or Lessee from such governmental authority for the use of such Airframe and Engines or engines after such time shall be paid over to, or retained by, Lessor unless Lessee shall have fully performed or, concurrently therewith, will fully perform the terms of Section 10.1 with respect to such Event of Loss. 10.5 Requisition of an Engine for Use by Governmental Authorities. In the event of the requisition for use by any governmental authority (other than in circumstances contemplated by Section 10.4) of any Engine but not the Airframe, Lessee will replace such Engine hereunder by complying with the terms of Section 10.2 to the same extent as if an Event of Loss had occurred with respect to such Engine, and any payments received by Lessor or Lessee from such governmental authority with respect to such requisition shall be paid over to, or retained by, Lessee (subject to performance by Lessee of the terms of Section 10.2 to the same extent as if an Event of Loss had occurred with respect to such requisitioned Engine). 10.6 Application of Payments During Existence of Default. Any amount referred to in this Section 10 which is payable or creditable to or retainable by Lessee shall not be paid or credited to or retained by Lessee if, at the time of such payment, credit or retention, (A) a Lease Event of Default or (B) a Lease Default under Section 14.1 or 14.5 shall have occurred and be continuing hereunder, but shall be paid to and held by Lessor as security for the obligations of Lessee under this Lease and applied against Lessee's obligations hereunder as and when due; at such time as there shall not be continuing any such Lease Event of Default or Lease Default, or at such earlier time as Lessee shall have paid in full all Rent and other amounts due and payable hereunder and under the other Operative Agreements by Lessee, any remaining balance of such amount shall be paid to Lessee to the extent not previously applied in accordance with the preceding clause of this sentence. Section 11. Insurance. 11.1 Public Liability and Property Damage Insurance. Lessee shall at all times maintain, or cause to be maintained, at its or any Permitted Sublessee's expense, SALE AND LEASE AGREEMENT 29 public liability (including without limitation contractual liability, passenger legal liability and property damage but excluding manufacturer's product liability coverage) insurance which shall: 11.1.1 Type, Form and Amount. Be of a type and form carried by similarly situated United States commercial air carriers generally, and carried in amounts not less than $350,000,000 (per occurrence) combined single limit (or such greater amount as Lessee may carry from time to time on other 737-200 series aircraft in its fleet); 11.1.2 Coverage. Include, but not be limited to, public liability insurance, contractual liability insurance, passenger liability insurance and property damage liability insurance (including cargo and baggage liability insurance); and 11.1.3 Additional Insureds. Name as additional insureds Lessor (in its individual and trust capacities), Lender and Owner Participant, as their interests may appear. 11.2 Insurance Against Loss of or Damage to Aircraft and Engines. Lessee shall at all times maintain, or cause to be maintained, at its or any Permitted Sublessee's expense insurance against loss of or damage to the Aircraft, Airframe and Engines as follows: 11.2.1 Type, Form and Amount. "All-risk" insurance on the Aircraft and "all-risk" coverage on each Engine and on Parts while removed from the Aircraft or Engines, which is of the type, form and in an amount in compliance with the last sentence of this Section 11.2.1, not less than that carried by Lessee on similar equipment owned or leased by Lessee and not less than that usually carried by similarly situated United States commercial air carriers; and, to the extent so usually carried, at all times that the Aircraft or any Engine is not covered by the insurance described in Section 11.2.2, coverage against the perils of (i) strikes, riots, civil commotions or labor disturbances, (ii) any malicious act or act of sabotage and (iii) hijacking, or any unlawful seizure or wrongful exercise of control, of the Aircraft or crew in flight (including any attempt at such seizure or control) made by any person or persons on board the Aircraft acting without the consent of the insured other than hijacking committed by persons engaged in a program of irregular warfare for terrorist purposes. Such insurance shall at all times be for an amount not less than Stipulated Loss Value for the Aircraft. 11.2.2 War-Risk Insurance. If at any time (a) war-risk insurance is maintained by Lessee or any Permitted Sublessee subleasing the Aircraft or any Engine with respect to other aircraft operated by Lessee or such Permitted Sublessee on the same or similar routes, or (b) the Aircraft is operated on routes where the custom in the SALE AND LEASE AGREEMENT 30 commercial airline industry is to carry war-risk insurance, then war-risk insurance of the type carried by similarly situated United States commercial air carriers operating the same or comparable models of aircraft on the same or similar routes shall be maintained on the Aircraft in an amount not less than that specified in Section 11.2.1. 11.2.3 Certain Requirements. The insurance policies required by this Section 11.2 shall: 11.2.3.1 Additional Insureds. Be endorsed to name Lessor (in its individual and trust capacities), Lender and Owner Participant as additional insureds, as their interests may appear. 11.2.3.2 Payment of Proceeds. Provide that proceeds thereunder shall be paid directly to Lender, so long as the Aircraft is subject to the Lien of the Mortgage and thereafter to Lessor, in either case as exclusive loss payee; provided, however, that any proceeds payable as a result of any property damage to the Airframe or any Engine, which property damage does not exceed $1,500,000 and does not constitute an Event of Loss with respect to the Aircraft or such Engine, shall be paid to Lessee, unless Lessor or Lender, prior to such payment, shall have notified the insurer making such payment that a Lease Event of Default or a Lease Default specified in Section 14.1 or 14.5 has occurred and is continuing. 11.2.3.3 Waiver of Subrogation. Provide that the insurers shall waive any rights of subrogation against Lessor, Lender and Owner Participant except for claims arising out of gross negligence or willful misconduct of such Persons; provided that the exercise by insurers of rights of subrogation, if any, permitted by this Section 11.2 shall not, in any way, delay payment of any claim that would otherwise be payable by such insurers but for the existence of such rights of subrogation or entitle such insurers to exercise or to assert any setoff, recoupment, counterclaim or any other deduction in respect of any amounts payable under such policies. 11.2.4 Deductibles. The insurance required by this Section 11.2 may, subject to Section 11.8, provide for standard deductibles which are from time to time in effect in the aviation insurance industry generally and which are customarily maintained by similarly situated United States commercial air carriers; provided, however, such deductibles shall not be more than the deductibles generally maintained by Lessee (and which Lessee is under no compulsion to maintain pursuant to any mortgage, lease or other agreement) with respect to its fleet of Boeing Model 737-200 series aircraft and Pratt & Whitney JT8D-9A engines generally. SALE AND LEASE AGREEMENT 31 11.2.5 Government Indemnity. In the case of a contract with the Government in respect of the Aircraft or Engines, a valid agreement by the Government to indemnify Lessee, Lessor, Lender and Owner Participant against the same risks which are required hereunder to be insured against in amounts at least equal to the amounts required hereunder from time to time (such indemnity to be backed by the full faith and credit of the United States of America), shall be considered adequate insurance with respect to the Aircraft, Airframe and any Engine subject to such contract to the extent of the risks and in the amounts that are the subject of any such agreement to indemnify. 11.3 General Policy Provisions. Each insurance policy to be procured and maintained hereunder shall: 11.3.1 Primary Insurance. Be primary and without right of contribution from other insurance which may provide coverage to Lessor, Lender or Owner Participant with respect to its interest in the Aircraft, Airframe or any Engine or its liabilities with respect to or arising out of the transactions contemplated by the Operative Agreements; 11.3.2 Coverage for Each Insured. Expressly provide that all the provisions thereof, except the agreed values and the limits of the liability of the insurer under such policy, shall operate in the same manner as if there were a separate policy covering each insured; 11.3.3 Waiver of Certain Rights. Waive any right of the insurers to any setoff, recoupment, counterclaim or any other deduction, whether by attachment or otherwise, in respect of any liability of Lessee, Lender, Lessor or Owner Participant; 11.3.4 Breach of Warranty. Provide that, in respect of Lessor, Lender and Owner Participant, such insurance shall not be invalidated by any action or inaction by Lessee or any additional insured (other than such additional insured, as to such additional insured) and shall insure the interests of Lessor, Lender and Owner Participant regardless of any breach or violation by Lessee or any additional insured (other than such additional insured, as to such additional insured) of any representation, warranty, declaration or condition contained in such policy; 11.3.5 Notice of Termination or Changes. Provide for not less than 30 days' prior written notice to be received by Lessor, Lender and Owner Participant before any lapse, alteration, termination or cancellation of the insurance evidenced thereby shall be effective as to Lessor, Lender and Owner Participant, except that war-risk and allied perils policies may provide for not less than seven days' prior written notice or such lesser or greater notice as shall at the time be customary in the aviation insurance SALE AND LEASE AGREEMENT 32 industry generally, and which are customarily in effect with respect to major United States commercial air carriers generally from time to time; 11.3.6 Nonliability for Premiums. Provide that neither Lessor, Lender nor Owner Participant shall be liable for any insurance premium; and 11.3.7 Identity of Insurers. Be with insurance companies, underwriters or funds of recognized responsibility. 11.4 Application of Insurance Proceeds. As between Lessor and Lessee, all insurance proceeds received under policies required to be maintained (or to be caused to be maintained) by Lessee pursuant to Section 11.2 as a result of the occurrence of an Event of Loss with respect to the Aircraft, Airframe or any Engine will be applied in accordance with Section 10.3.1 or 10.3.2, as the case may be (except that the balance referred to in Section 10.3.2 shall be paid over to, or retained by, Lessee). All insurance proceeds in respect of any property damage loss not constituting an Event of Loss with respect to the Airframe or an Engine will be applied in payment for repairs or for replacement property in accordance with the terms of Section 8, if not already paid for by Lessee, and any balance remaining after compliance with such Section with respect to such loss shall be paid to Lessee. In the case of a loss with respect to an engine (other than an Engine) installed on the Airframe, Lessor shall hold any payment to it of any insurance proceeds in respect of such loss for the account of Lessee or any other third party that is entitled to receive such proceeds. The provisions of Section 10.6 shall apply to amounts referred to in this Section 11.4. 11.5 Certificates; Reports. Etc. With respect to any policy required hereunder, Lessee shall cause to be furnished to Lessor and each Participant on or prior to the Delivery Date of the Aircraft and on or prior to expiration of such policy, certificates of the insurer or insurers (or their authorized representatives) providing insurance pursuant to the requirements of this Section 11, as to hull and liability insurance. On or before the Delivery Date of the Aircraft, and annually thereafter on or before such expiration date, Lessee shall cause to be furnished to Lessor and each Participant a report signed by Frank B. Hall & Co. (or any other firm of independent aircraft insurance brokers, appointed by Lessee, reasonably satisfactory to the Participants) describing in reasonable detail the insurance then carried and maintained with respect to the Aircraft and stating the opinion of such firm that the insurance then carried and maintained on the Aircraft complies with the terms hereof as to hull and liability insurance. Lessee agrees that it will cause such firm to advise Lessor and each Participant in writing promptly of any default in the payment of any premium or any other act or omission on the part of Lessee or any Permitted Sublessee of which they have knowledge and which might invalidate or render unenforceable, in whole or in part, the insurance on the Aircraft. To the extent such agreement is reasonably obtainable, Lessee further agrees to cause such SALE AND LEASE AGREEMENT 33 firm to advise Lessor and each Participant in writing at least 30 days (seven days in the case of war-risk and allied perils coverage) prior to the expiration or termination date of any insurance carried and maintained on the Aircraft pursuant to this Section 11. 11.6. Lessor's Right to Maintain Insurance. In the event that Lessee shall fail to maintain or cause to be maintained insurance as herein provided, Lessor or any Participant may at its option (but shall not be obligated to) provide such insurance and in such event, Lessee shall, upon demand, reimburse such Person, as Supplemental Rent, for the cost thereof. No such payment, performance or compliance shall be deemed to cure any Lease Event of Default or Lease Default or otherwise relieve Lessee of its obligations with respect thereto. At Lessor's or Lender's request and expense, and subject to the permission of Lessee's insurance carriers, Lessee will increase the amount of coverage under any insurance policy that Lessee maintains pursuant to Section 11.2.1 or 11.2.2, and notwithstanding the provisions of Section 11.4, the proceeds of any such additional insurance shall be payable to Lessor or Lender, as the case may be; provided, however, that no such insurance may be obtained which would limit or otherwise adversely affect the availability or coverage or cost of any insurance required to be obtained or maintained pursuant to this Section 11. 11.7 Insurance for Own Account. Nothing in this Section 11 shall limit or prohibit Owner Participant (directly or through Lessor) from obtaining insurance for its own account, and any proceeds payable thereunder shall be payable as provided in the insurance policy relating thereto; provided, however, that no such insurance may be obtained which would limit or otherwise adversely affect the availability or coverage or cost of any insurance required to be obtained or maintained pursuant to this Section 11. Nothing in this Section 11 shall limit or prohibit Lessor or Lender from obtaining insurance for its own account, and any proceeds payable thereunder shall be payable as provided in the insurance policy relating thereto; provided, however, that no such insurance may be obtained which would limit or otherwise adversely affect the availability or coverage or cost of any insurance required to be obtained or maintained pursuant to this Section 11 or obtained by Owner Participant pursuant to the preceding sentence. 11.8 Self-Insurance. Notwithstanding the foregoing provisions of this Section 11, Lessee may, from time to time, self-insure with respect to the Aircraft to the same extent as it does with respect to, or maintain policies with deductibles or premium adjustment provisions consistent with similar provisions applicable to, other comparable aircraft operated by Lessee; provided, however, that if at any time Lessee's unsecured senior long-term debt securities are not rated "Investment Grade", in the case of hull insurance such self-insurance shall in no case be in an amount greater than 4% of Lessee's tangible net worth (as defined in accordance with accepted financial practice); and provided, further that, in the case of public liability insurance, such self-insurance shall in no event exceed $50,000,000. As used in this Section 11.8, the term "Investment Grade" SALE AND LEASE AGREEMENT 34 means a rating of "Baa3" or higher from Moody's Investors Service, Inc. or a rating from any other nationally recognized bond rating service equivalent to or better than such a rating. Section 12. Inspection. At all reasonable times, and upon reasonable notice, Lessor or any Participant or its authorized representatives or designees may inspect the Aircraft and inspect and copy (subject to any confidentiality agreements, copyright restrictions and the like) the books and records of Lessee relative thereto. Any such inspection of the Aircraft shall be without out-of-pocket expense or risk to Lessee; provided that no exercise of such inspection right shall interfere with the normal operation or maintenance of the Aircraft by, or the business of, Lessee (or any Permitted Sublessee). Subject to the proviso to the preceding sentence of this Section 12, Owner Participant may observe the "C" check (or its equivalent) referred to in clause (I) of Section 5.3.1 and any Card inspection during the Term. Neither Lessor nor any Participant shall have any duty to make any such inspection and shall not incur any liability or obligation by reason of not making any such inspection. Section 13. Assignment. 13.1 General. Except as otherwise expressly permitted in Section 7.2 hereof or Section 12.5.1 of the Participation Agreement, or as required in the case of any requisition by the Government referred to in Section 7.1.4, Lessee will not, without the prior written consent of Lessor, assign or transfer any of its rights or obligations under this Lease. Lessor may assign or convey any of its right, title and interest in and to this Lease or the Aircraft in accordance with the Participation Agreement, the Trust Agreement or the express provisions of this Lease. The terms and provisions of the Lease shall be binding upon and inure to the benefit of Lessor and Lessee and their respective permitted successors and assigns. 13.2 Security for Lessor's Obligations. In order to secure the indebtedness evidenced by the Note, the Mortgage provides, among other things, for the assignment by Lessor to Lender of its right, title and interest in, to and under this Lease and any Permitted Sublease, to the extent set forth in the Mortgage, and for the creation of a first mortgage lien on and perfected security interest in the Aircraft in favor of Lender.

Lessor may sell all or any part of the Aircraft, Airframe or any Engine, at public or private sale, at such times and places, to such Persons (including Lessor or any Participant) as Lessor may determine, or otherwise dispose of, hold, use, operate, lease to others or keep idle the Aircraft, Airframe or any Engine or part thereof, as Lessor, in its sole discretion, may determine, all free and clear of any rights of Lessee except as hereinafter set forth in this Section 15 and without any duty to account to Lessee with respect to such action or inaction or for any proceeds with respect thereto; or 15.1.3 Certain Liquidated Damages. 15.1.3.1 Liquidated Damages--Fair Market Rental Value. Whether or not Lessor shall have exercised, or shall thereafter at any time exercise, any of its rights under Section 15.1.1 or 15.1.2 with respect to the Aircraft, Airframe or any Engine or part thereof, Lessor, by written notice to Lessee specifying a payment date not earlier than ten days from the date of such notice, may cause Lessee to pay to Lessor, and Lessee shall pay to Lessor, on the payment date specified in such notice, as liquidated damages for loss of a bargain and not as a penalty (in lieu of the Basic Rent or Renewal Rent, as the case may be, due on or after the date specified for payment in such notice), any unpaid Basic Rent or Renewal Rent, as the case may be, due prior to such date plus an amount equal to the excess, if any, of the Stipulated Loss Value for the Aircraft, computed as of such date over the fair market rental value (determined as hereafter provided in this Section 15) of the Aircraft for the remainder of the Term, after discounting such fair market rental value semiannually (effective on each Rent Payment Date) by a rate equal to the Overdue Rate to present worth as of the date specified for payment in such notice, together with interest, if any, on such amount and unpaid Basic Rent or Renewal Rent, as the case may be, at the Overdue Rate from the date specified for payment in such notice to the date of payment in full; or 15.1.3.2 Liquidated Damages--Fair Market Sales Value.

If Lessor, pursuant to Section 15.1.2 or applicable law, shall have sold the Aircraft, Lessor, in lieu of exercising its rights under Section 15.1.3 with respect to the Aircraft, may, if Lessor shall so elect, upon giving written notice to Lessee, cause Lessee to pay Lessor, and Lessee shall pay to Lessor, on the date of such sale, as liquidated damages for loss of a bargain and not as a penalty (in lieu of the Basic Rent or Renewal Rent, as the case may be, due on or after the date of such sale), any unpaid Basic Rent or Renewal Rent, as the case may be, due prior to such date of sale plus the amount of any deficiency between the net proceeds of such sale or (if such sale is a private sale and is made to Lessor, a Participant or any Affiliate thereof) between the fair market sales value of the Aircraft, determined as of the date of such sale as hereinafter provided in this Section 15, and the Stipulated Loss Value of the Aircraft, computed as of the date of such sale, together with interest, if any, on such amount and such unpaid Basic Rent or Renewal Rent at the Overdue Rate from the date of such sale to the date of payment in full; or 15.1.5 Rescission and Other Remedies. Lessor may terminate or rescind this Lease as to the Aircraft, or may exercise any other right or remedy which may be available to it under applicable law or proceed by appropriate court action to enforce the terms hereof or to recover damages for the breach hereof, including without limitation Lessee's agreement to lease the Aircraft for the Term and to pay Rent. In addition to the foregoing remedies, Lessee shall be liable (except as otherwise provided above and without duplication of amounts otherwise payable hereunder) for any and all unpaid Rent due hereunder before, during or after the exercise of any of the foregoing remedies and for all reasonable and actual legal fees and other costs and expenses (including the fees and expenses of all appraisers required by this Section 15) of Lessor and Participants, incurred by reason of the occurrence of any Lease Event of Default or the exercise of Lessor's remedies with respect thereto, including all insurance and storage costs and all costs and expenses incurred in connection with the return of the Aircraft, Airframe or any Engine or part thereof, in accordance with the terms of Section 5 or in placing the Aircraft, Airframe or any Engine or part thereof, in the condition and airworthiness required by Section 5. Lessor agrees to give Lessee at least 15 days' prior written notice of the date fixed for any public sale of the Aircraft, the Airframe or any Engine or part thereof, and of the date on or after which will occur the execution of any contract providing for any private sale, and any such public sale shall be conducted in general so as to afford Lessee a reasonable opportunity to bid. SALE AND LEASE AGREEMENT 39 15.2 Determination of Fair Market Rental Value and Fair Market Sales Value. For the purpose of this Section 15, the "fair market rental value" or the "fair market sales value" of the Aircraft shall be the rental value or sales value, as the case may be, which would be obtained in an arm's-length transaction between an informed and willing lessee or purchaser, as the case may be, under no compulsion to lease or purchase, as the case may be, and an informed and willing lessor or seller in possession, as the case may be, and in each case shall be determined on an "as is, where is" basis pursuant to an appraisal by a recognized independent aircraft appraiser chosen by Lessor and approved by Lessee, which approval shall not be unreasonably withheld or delayed and shall be deemed granted if such choice is not rejected within 10 days after Lessee's receipt of notice of Lessor's choice. 15.3 No Waiver, Etc. No remedy referred to in this Section 15 is intended to be exclusive, but each shall be cumulative and in addition to any other remedy referred to above or otherwise available to Lessor at law or in equity; and the exercise or beginning of exercise by Lessor of any one or more of such remedies shall not preclude the simultaneous or later exercise by Lessor of any or all of such other remedies. No express or implied waiver by Lessor of any Lease Event of Default shall in any way be, or be construed to be, a waiver of any earlier or subsequent Lease Event of Default. To the extent permitted by applicable law, Lessee hereby waives any rights now or hereafter conferred by statute or otherwise which may require Lessor to sell, lease or otherwise use the Aircraft, Airframe or any Engine, or part thereof, in mitigation of Lessor's damages as set forth in this Section 15 or which may otherwise limit or modify any of Lessor's rights or remedies under this Section 15. Section 16. Notices. All notices required under the terms and provisions hereof shall be in writing and shall be given by certified mail, telecopy or any other customary means of written communication, addressed: If to Lessee, at 2702 Love Field Dr., P.O.

SALE AND LEASE AGREEMENT 40 The effective date of any such notice shall be the date on which it is received by the addressee. Lessee shall furnish to Lessor for transmission to Owner Participant and Lender a sufficient number of copies of all reports, notices, requests, demands, certificates, financial statements and other instruments furnished hereunder, except in any case where Lessee shall have transmitted the same directly to any such person. Section 17. Net Lease; Lessee's Obligations; No Setoff, Counterclaim, Etc. This is a net lease and it is hereby recognized that Lessor is the owner of the Aircraft (except that Owner Participant will be the owner for income tax purposes) and Lessee is the lessee thereof. It is the intent of the parties hereto that this Lease be a "true lease". Lessee's obligation to pay all Rent payable hereunder shall be absolute and unconditional and shall not be affected by any circumstance, including without limitation: (a) any setoff, counterclaim, recoupment, defense or other right which Lessee may have against Lessor (in its individual or trust capacity), any Participant, any Indemnified Party or any other Person for any reason whatsoever (except as expressly provided in Section 13.5.2 of the Participation Agreement or in Sections 6 and 7 of the Tax Indemnification Agreement); (b) any defect in the title, airworthiness, condition, design, operation or fitness for use of, or any damage to or loss or destruction of, the Aircraft, Airframe or any Engine, or any interruption or cessation in the use or possession thereof by Lessee for any reason whatsoever; (c) any insolvency, bankruptcy, reorganization or similar proceedings by or against Lessee; (d) any restriction, prevention or curtailment of or interference with any use of the Aircraft or part thereof; (e) any invalidity or unenforceability or disaffirmance of this Lease or any provision hereof or any of the other Operative Agreements or any provision thereof, in each case whether against or by Lessee or otherwise; or (f) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. If for any reason whatsoever this Lease shall be terminated in whole or in part by operation of law or otherwise except as specifically provided herein, Lessee nonetheless agrees to pay an amount equal to each Basic Rent, Renewal Rent and Supplemental Rent payment at the time such payment would have become due and payable in accordance with the terms hereof had this Lease not been terminated in whole or in part. All Rent payable by Lessee shall be paid without notice or demand (except as otherwise expressly provided) and without abatement, suspension, deferment, deduction, diminution or proration by reason of any circumstance or occurrence whatsoever (except as expressly provided in Section 13.5.2 of the Participation Agreement or in Sections 6 and 7 of the Tax Indemnification Agreement). Lessee hereby waives, to the extent permitted by applicable law, any and all rights which it may now have or which at any time hereafter may be conferred upon it, by statute or otherwise, to terminate, cancel, quit or surrender this Lease or any part hereof, or to any abatement, suppression, deferment, diminution, reduction or proration of Rent except in accordance with the express terms hereof. Each SALE AND LEASE AGREEMENT 41 payment of Rent made by Lessee shall be final as to Lessor and Lessee. Lessee will not seek to recover all or any part of any such payment of Rent for any reason whatsoever. Section 18. Renewal Options; Early Termination. 18.1 Renewal Options. At the end of the Base Lease Term or any Renewal Term, so long as no Lease Event of Default or Lease Default has occurred and is continuing and the aggregate of all Renewal Terms shall not exceed six years, Lessee shall have the option to renew this Lease for a Renewal Term; provided, that if, at the time of exercise by Lessee of any of its renewal rights set forth in this Section 18.1, Owner Participant and its Affiliates shall be the owner of all of the beneficial interest in one or more other Boeing Model 737-200 series aircraft then subject to a lease under which the lessee is Lessee (all of such aircraft, together with the Aircraft, referred to as the "Owner Group Aircraft"), then Lessee shall be obligated to exercise such renewal rights (or to have exercised such renewal rights for a Renewal Term which shall be then continuing) with respect to at least three of such Owner Group Aircraft (or such lesser number of Owner Group Aircraft as shall exist at such time). In order to exercise the option to renew, except as otherwise provided in Section 13.4.1 of the Participation Agreement, Lessee shall notify Lessor thereof in writing not more than 360 days nor less than 180 days prior to the commencement of the applicable Renewal Term (which notice shall be irrevocable). The Renewal Rent payable for such Renewal Term hereunder shall be the fair market rental value of the Aircraft calculated as of the commencement of such Renewal Term; provided, that if a Stage III Upgrade shall have occurred and (i) Owner Participant shall have performed its obligations set forth in Section 13.4 of the Participation Agreement, upon proper request by Lessee, then such fair market value shall be determined taking into account the value of the hush kit installed pursuant to such upgrade, and (ii) if Owner Participant shall not have so performed or shall not have been requested to do so by Lessee, then such fair market value shall be determined without taking into account the value of the hush kit installed pursuant to such upgrade, i.e., as if no Stage III Upgrade had occurred. Such fair market rental value shall be determined not later than three months prior to the commencement of such Renewal Term by mutual consent of Owner Participant and Lessee or, if they shall be unable so to agree, by three recognized independent aircraft appraisers, one chosen and paid for by Owner Participant, one chosen and paid for by Lessee and the third appraiser chosen by the mutual consent of the first two appraisers and paid for equally by Owner Participant and Lessee, the appraisals of which three appraisers shall be averaged and such average shall be deemed to be the fair market rental value of the Aircraft for all purposes hereof; provided, however, that if the appraisal of one appraiser is more disparate from the average of all three appraisals than each of the other two appraisals, then the appraisal of such appraiser shall be excluded, the remaining appraisals shall be averaged and such average shall be deemed to be the fair market rental value of the Aircraft for all purposes hereof. If either Owner Participant or Lessee shall fail to appoint an appraiser by the date which is two months SALE AND LEASE AGREEMENT 42 prior to the commencement of such Renewal Term or if such two appraisers cannot agree on the amount of such appraisal and fail to appoint a third appraiser by the date which is one month before the commencement of such Renewal Term, then either Owner Participant or Lessee may apply to any court having jurisdiction to make such appointment. Fair market rental value shall be the cash rental obtainable in an arm's-length lease between an informed and willing lessee (under no compulsion to lease) and an informed and willing lessor (under no compulsion to lease) and shall be determined on the assumptions that the Aircraft is in the United States of America, available for use by the lessee and in the return condition required by Section 5 of this Lease and otherwise in compliance with the requirements of this Lease. Stipulated Loss Value amounts that are payable during each such Renewal Term shall be calculated as of the date of commencement of such Renewal Term and shall be determined by multiplying 1.1 times the appraised value of the Aircraft at such time; provided, however, that no such amount shall be less than the principal amount of any indebtedness then secured by a Lien on the Aircraft. 18.2 Early Termination. Provided that this Lease has not been terminated and provided that no Lease Default or Lease Event of Default shall have occurred and be continuing hereunder, Lessee shall have the option to terminate this Lease with respect to the Aircraft not more than 42 days prior to the expiration of the Base Lease Term or the applicable Renewal Term. Lessee may exercise such option of termination by delivering irrevocable written notice of such exercise to Lessor not less than six months' prior written notice of such advanced date of termination. Such notice shall provide the date elected by Lessee for such early termination and a calculation of the final payment of Rent, which shall be due on such early termination date and shall be calculated as provided in clause (ii) of Section 3.3. 18.3 Default Purchase Option. In the event of Owner Participant's failure to satisfy its obligations specified in Section 13.4 of the Participation Agreement, Lessee shall have the option to purchase the Aircraft. In order to exercise such option, Lessee shall notify Lessor (and, if the Mortgage is then in effect, Lender) thereof in writing, specifying a Rent Payment Date on which such purchase is to occur. In such case, Lessee shall purchase the Aircraft on such Rent Purchase Date at a purchase price equal to Termination Value. Upon receipt of such purchase price from Lessee and all Rent and other amounts due hereunder and under any other Operative Agreement, Lessor shall Transfer to Lessee the Aircraft. Section 19. Successor Owner Trustee. Lessee agrees that in the case of the appointment of any successor Owner Trustee pursuant to the terms of the Trust Agreement, such successor Owner Trustee shall, upon written notice by such successor Owner Trustee to Lessee, succeed to all the rights, powers and title of Lessor hereunder and shall be deemed to be Lessor and the owner of the Aircraft for all purposes hereof SALE AND LEASE AGREEMENT 43 without the necessity of any consent or approval by Lessee (but such successor Owner Trustee shall qualify under the terms of Section 10.2 of the Participation Agreement) and without in any way altering the terms of this Lease or Lessee's obligations hereunder. One such appointment and designation of a successor Owner Trustee shall not exhaust the right to appoint and designate further successor or additional Owner Trustees pursuant to the Trust Agreement, and such right may be exercised repeatedly as long as this Lease shall be in effect. Section 20. Right to Perform for Lessee. If Lessee fails to make any payment of Rent required to be made by it hereunder or fails to perform or comply with any of its agreements contained herein, Lessor may (but shall not be obligated to) make such payment or perform or comply with such agreement, and the amount of such payment and the amount of the expenses of Lessor incurred in connection with such payment or the performance of or compliance with such agreement, as the case may be, together with interest thereon at the Overdue Rate, shall be deemed Supplemental Rent, payable by Lessee upon demand. Section 21. Quiet Enjoyment. So long as this Lease shall not have been declared to be in default pursuant to Section 15, during the Term Lessor will not, through its own actions or inactions, interfere in the quiet enjoyment of the Aircraft by Lessee or any Permitted Sublessee. Section 22. Investment of Security Funds; Miscellaneous; Amendment. 22.1 Investment of Security Funds. Any moneys required to be paid to or retained by Lessor which are not required to be paid to Lessee pursuant to Section 10.6 or 11.4 solely because a Lease Event of Default or Lease Default under Section 14.1 or 14.5 shall have occurred and be continuing, or which are held by Lessor pending payment to Lessee pursuant to Section 11.4 or which are required to be paid to Lessee pursuant to Section 10.3 or 11.4 after completion of a replacement to be made pursuant to Section 10.2, shall, until paid to Lessee as provided in Section 10 or 11 or applied as provided herein or in the Trust Agreement, be invested by Lessor from time to time as directed in writing by Lessee and at the expense and risk of Lessee in the following securities (which, except in the case of the shares described in clause (e) below, shall mature within 91 days of the date of purchase thereof): (a) direct obligations of the Government; (b) obligations fully guaranteed by the Government; (c) open market commercial paper of any corporation incorporated under the laws of the United States of America or any State thereof rated P-1 or its equivalent by Moody's Investors Service, Inc. and A-1 or its equivalent by Standard & Poor's Corporation; or (d) certificates of deposit issued by, or bankers' acceptances of, or time deposits or a deposit account with any bank, trust company or national banking association incorporated or doing business under the laws of the United States of America or any state thereof having a combined capital and SALE AND LEASE AGREEMENT 44 surplus of at least $50,000,000; or (e) shares of a money market fund registered under the Investment Company Act of 1940, as amended, the sole assets of which are direct obligations of the Government. There shall be promptly remitted to Lessee or its order any gain (including interest received) realized as the result of any such investment (net of any fees, commissions and other expenses, if any, incurred in connection with such investment) unless a Lease Event of Default of a Lease Default under Section 14.1 or 14.5 shall have occurred and be continuing. Lessee will promptly pay to Lessor, on demand, the amount of any loss realized as the result of any such investment (together with any fees, commissions and other expenses, if any, incurred in connection with such investment), such amount to be disposed of in accordance with the terms of the Trust Agreement. 22.2 Miscellaneous; Amendment. Lessee shall do, execute, acknowledge and deliver, or shall cause to be done, executed, acknowledged and delivered, all such further acts, conveyances and assurances as Lessor or any Participant shall reasonably require for accomplishing the purposes of this Agreement and the other Operative Agreements. Any provision of this Lease which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable law, Lessee hereby waives any provision of law which renders any provision hereof prohibited or unenforceable in any respect. No term or provision of this Lease may be changed, waived, discharged or terminated orally, but only by an instrument in writing signed by the party against which the enforcement of the change, waiver, discharge or termination is sought. This Lease shall constitute an agreement of lease, and nothing herein shall be construed as conveying to Lessee any right, title or interest in or to the Aircraft, Airframe or Engines except as a lessee only. The section and paragraph headings in this Lease and the table of contents are for convenience of reference only and shall not modify, define, expand or limit any of the terms or provisions hereof and all references herein to numbered sections, unless otherwise indicated, are to sections of this Lease.
