3.3               Requests and Approvals

                  In the event that the Buyer files a Request for Change
                  ("RFC") with the Seller and the RFC does not subsequently
                  become an SCN for any reason, such RFC will be cancelled
                  without charge to the Buyer. Upon receipt of any request
                  for a proposed change, the Seller will consider such
                  request in good faith and will respond within ten (10)

                  Development Changes) in an Aircraft and the Seller agrees
                  to such request and incorporates such change, but the
                  change is not subsequently made the subject of an SCN for
                  any reason (other than the Seller's unreasonable refusal
                  to sign the SCN or otherwise acting in bad faith), the
                  Buyer will pay to the Seller the actual direct cost of
                  design and other work resulting from such request and
                  incurred by the Seller ***. In the event that the Buyer
                  requests the Seller in writing to proceed with a proposed
                  change before any requisite approval of DGAC and FAA has
                  been obtained and subsequently such DGAC or FAA approval
                  is not obtained, any SCN which will have been executed in
                  connection with such proposed change will be deemed
                  canceled. ***

                  delivery of any Aircraft will be postponed by reason of
                  such change, the delivery date of such Aircraft as
                  provided in Subclause 9.1 will be extended to the extent
                  required by reason of such change, ***.

                  The Seller will use all reasonable efforts to ensure that
                  each Aircraft that is the subject of such postponement is

                  collected by withholding), which are levied, assessed,
                  charged or collected for or in connection with the sale,

                  Aircraft, component, accessory, equipment or part
                  delivered or furnished hereunder, provided such taxes,
                  duties, imposts or similar charges have been promulgated
                  and are enforceable under any laws ***.

4.4.3             If a claim is made against one party (the "Indemnitee")
                  for any taxes, duties, imposts or similar charges for
                  which the other party (the "Indemnitor") has agreed to be
                  liable pursuant to the provisions of this Agreement, the
                  Indemnitee will promptly notify the Indemnitor. In lieu
                  of any direction or request by the Indemnitor received
                  within five (5) Working Days of the due date specified in
                  said claim, the Indemnitee may pay the amount of said
                  tax, duty, impost or charge and claim against the
                  Indemnitor for reimbursement consistent with Subclause
                  4.4. However, if requested by the Indemnitor in writing,
                  the Indemnitee will, at the Indemnitor's expense, take
                  such action as the Indemnitor may reasonably direct with
                  respect to such asserted liability and will not pay such
                  taxes, duties, imposts or similar charges except under
                  protest, if protest is necessary. If payment is made, the
                  Indemnitee will, at the Indemnitor's expense, take such
                  action as the Indemnitor may reasonably direct to recover
                  payment and will, if requested, permit the Indemnitor in
                  the Indemnitee's name to file a claim or commence an
                  action to recover such payment. If the Indemnitee will
                  receive a refund or credit for all or any part of such
                  taxes, duties, imposts or similar charges, then the
                  Indemnitee will promptly repay the Indemnitor the amount
                  of any such refund or credits which are attributable to
                  the amount paid by the Indemnitor, including any interest
                  received thereon, but less any expenses incurred by the
                  Indemnitee in pursuing such refund or credit.

                  materials and parts thereof will at all reasonable times
                  during business hours be open to inspection by duly
                  authorized representatives of the Buyer or its designee
                  at the respective works of the Associated Contractors
                  and, if possible, at the works of their respective
                  subcontractors, and such representatives will, to carry

                  relevant technical data as is reasonably necessary for

                  respective works where construction is in progress or
                  materials or parts are stored is restricted for security
                  reasons, the Associated Contractors will be allowed a
                  reasonable time to make the items available for
                  inspection elsewhere). The actual detailed inspection of
                  the Aircraft, materials and parts thereof will take place
                  only in the presence of the respective inspection
                  department personnel of the Associated Contractors or

                  inspection, based on modifications to the Manufacturer's
                  Quality Instruction document.

                  representatives of the Buyer during the aforementioned
                  period.

                  Seller's, the Associated Contractors' or their respective
                  subcontractors' engineering or other personnel by the
                  Buyer and its said representatives will be performed in
                  such manner as not to unreasonably delay or hinder the
                  work to be carried out on the Aircraft or the proper
                  performance of this Agreement. In no event will the Buyer
                  or its representatives be permitted to inspect any
                  aircraft other than the Aircraft. The Seller will not
                  permit, and will cause the Manufacturer not to permit,
                  any representatives, employees, agents or personnel of
                  any other airline or customer to inspect, or to have
                  access to, the Aircraft or any designs or specifications

                  GROSS NEGLIGENCE.

7.2.4             CLAIMS

                  IN THE EVENT ANY CLAIM IS MADE OR LAWSUIT IS BROUGHT
                  AGAINST EITHER PARTY (OR ITS RESPECTIVE DIRECTORS,
                  OFFICERS, AGENTS OR EMPLOYEES) FOR DAMAGES FOR DEATH OR
                  INJURY, OR FOR PROPERTY DAMAGE, THE LIABILITY FOR WHICH
                  HAS BEEN ASSUMED BY THE OTHER PARTY PURSUANT TO THIS
                  SUBCLAUSE 7.2, THE FORMER (INDEMNITEE) WILL PROMPTLY GIVE
                  NOTICE TO THE OTHER PARTY (INDEMNITOR), AND THE
                  INDEMNITOR WILL HAVE THE RIGHT TO INVESTIGATE, AND THE
                  RIGHT IN ITS SOLE DISCRETION TO ASSUME AND CONDUCT THE
                  DEFENSE OF OR SETTLE OR COMPROMISE, SUCH CLAIM, ACTION,
                  PROCEEDING OR LAWSUIT. HOWEVER, IF IN THE REASONABLE
                  OPINION OF THE INDEMNITEE, SUCH DEFENSE, SETTLEMENT OR
                  COMPROMISE INVOLVES THE POTENTIAL IMPOSITION OF CRIMINAL
                  LIABILITY ON THE INDEMNITEE OR A CONFLICT OF INTEREST
                  BETWEEN THE INDEMNITOR AND THE INDEMNITEE, THE INDEMNITOR
                  WILL NOT BE ENTITLED TO ASSUME AND CONDUCT THE DEFENSE OF
                  ANY SUCH CLAIM, ACTION, PROCEEDING OR LAWSUIT. THE
                  INDEMNITEES WILL BE ENTITLED, AT THEIR OWN EXPENSE,
                  ACTING THROUGH ONE (1) COUNSEL, TO PARTICIPATE IN ANY
                  CLAIM, ACTION, PROCEEDING OR LAWSUIT THE DEFENSE OF WHICH
                  HAS BEEN ASSUMED BY THE INDEMNITOR PURSUANT TO THE
                  PRECEDING PROVISIONS, PROVIDED, THAT SUCH PARTICIPATION
                  DOES NOT, IN THE REASONABLE OPINION OF INDEPENDENT
                  COUNSEL OF THE INDEMNITOR, INTERFERE WITH THE CONDUCT OF
                  SUCH DEFENSE. NOTWITHSTANDING ANYTHING TO THE CONTRARY,
                  NO SETTLEMENT OR COMPROMISE WILL BE ENTERED INTO WITHOUT
                  THE PRIOR WRITTEN CONSENT OF THE INDEMNITEE, WHICH
                  CONSENT WILL NOT BE UNREASONABLY WITHHELD OR DELAYED.
                  EACH INDEMNITEE WILL COOPERATE WITH THE INDEMNITOR IN THE
                  INVESTIGATION AND CONDUCT OF THE DEFENSE OF ANY CLAIM,
                  ACTION, PROCEEDING OR LAWSUIT INDEMNIFIED HEREUNDER.

                  IN THE EVENT THAT THE INDEMNITOR DOES NOT ASSUME AND
                  CONDUCT THE DEFENSE OF THE CLAIM OR LAWSUIT, THEN THE
                  INDEMNITEE WILL HAVE THE RIGHT TO PROCEED WITH DEFENSE OF
                  THE CLAIM OR LAWSUIT AS IT DEEMS APPROPRIATE AND WILL
                  HAVE AN ACTION AGAINST THE INDEMNITOR FOR ANY JUDGMENTS,
                  SETTLEMENTS, COSTS OR EXPENSES INCURRED IN CONDUCTING
                  SAID DEFENSE. FOR THE PURPOSE OF THIS SUBCLAUSE 7.2, A
                  CLAIM OR LAWSUIT AGAINST THE MANUFACTURER OR ANY OF THE
                  ASSOCIATED CONTRACTORS OR ANY OF THEIR RESPECTIVE
                  SUBCONTRACTORS OR ANY OF THEIR RESPECTIVE DIRECTORS,
                  OFFICERS, AGENTS OR EMPLOYEES WILL BE DEEMED TO BE A
                  LAWSUIT AGAINST THE SELLER.


8 -               BUYER'S ACCEPTANCE

8.1               Acceptance Procedures

8.1.1             The Seller or any Affiliate thereof acting as the
                  Seller's designee will give to the Buyer not less than
                  thirty (30) days' notice of the proposed date and time
                  when the Buyer's acceptance tests will be conducted, and,
                  in the event that the Buyer elects to attend the said
                  tests, the Buyer will cooperate in complying with the
                  reasonable requirements of the Seller with the intention
                  of completing all tests within five (5) Working Days
                  after commencement. The tests will take place at
                  Aerospatiale's works near Toulouse, France, and will be
                  carried out by the personnel of the Manufacturer
                  (accompanied, if the Buyer so wishes, by representatives
                  of the Buyer up to a total of six (6) (or more if
                  reasonably requested by the Buyer) acting as observers,
                  of whom not more than two (2) will have access to the
                  cockpit at any one time and of whom one (1) may act as
                  copilot, subject to such person's appropriate
                  certification). During flight tests, these
                  representatives will comply with the instructions of the
                  Manufacturer's representatives. The Manufacturer will not
                  normally be required in the course of such acceptance
                  tests to fly any of the Aircraft for more than an
                  aggregate of three (3) hours, unless more time is
                  necessary to complete the acceptance tests.

8.1.2             The Seller will cause ASC, at no cost to the Buyer, to
                  brief, and provide one (1) free-of-charge four (4) hour
                  simulator session for each new set of acceptance pilots.
                  This briefing will provide specific information related
                  to acceptance flights.

8.1.3             The acceptance tests will be designed to demonstrate the
                  satisfactory functioning of the Aircraft and all systems
                  relating thereto, and compliance with the terms,
                  requirements and conditions of this Agreement, including
                  conformity to the Specifications and ***. During such
                  acceptance tests the Seller will make available to the
                  Buyer all records and logs relating to the Aircraft and
                  related systems, and the Buyer will have access to
                  interior equipment, parts and components and will be
                  permitted to perform ground checks, and, with respect to
                  the Propulsion Systems, engine runs, engine borescoping
                  and performance acceptance checks. The successful
                  completion of such acceptance tests will also be deemed
                  to demonstrate compliance with the Specifications. The
                  acceptance tests will be conducted in accordance with the
                  Manufacturer's aircraft acceptance procedure, as amended
                  to incorporate the Buyer's reasonable requests. At the
                  time of delivery, the Aircraft will comply with all
                  relevant limits and tolerances specified in the Aircraft
                  Maintenance Manual. In the event that the Buyer does not
                  attend the tests or fails to so cooperate, the Seller may
                  complete them in the absence of the Buyer, provided that
                  the Seller has given the Buyer reasonable prior written
                  notice of not less than seven (7) days of its intention
                  to complete such tests and the Buyer remains absent or
                  uncooperative. The Buyer will be deemed to have accepted
                  the tests, if such tests are reasonably deemed
                  satisfactory by the Seller, and the Seller will furnish
                  such data with respect to such tests as the Buyer may
                  reasonably request. Notwithstanding the above, said
                  acceptance by the Buyer will not impair the rights of the
                  Buyer that derive from the warranties relating to the
                  Aircraft.

8.1.4             If the acceptance tests for an Aircraft are not
                  successfully completed or there is a defect, the Buyer,
                  within two (2) days after such tests, will give notice to
                  the Seller specifying such unsuccessful completion or
                  defect. Thereafter the Seller will, without unreasonable
                  hindrance from the Buyer, carry out any necessary changes
                  and, as soon as practicable thereafter, resubmit the
                  Aircraft for new acceptance tests, including flight tests
                  if necessary, demonstrate the elimination of the defect,
                  such tests to be held and carried out in accordance with
                  this Subclause 8.1. In order to avoid a delay in the
                  delivery of any Aircraft found to have one or more
                  defects, the Buyer may elect with the consent of the
                  Seller (such consent not to be unreasonably withheld) to
                  take delivery of such Aircraft prior to the correction of
                  such defects and without prejudice to any rights the
                  Buyer may have under this Agreement against the Seller by
                  reason of such defects.

                  In the event the Buyer elects to take delivery of an
                  Aircraft with defects pursuant to the preceding
                  paragraph, delivery of such Aircraft will be made as
                  originally scheduled, and such defects will be corrected,
                  at the Seller's expense, by the Buyer or the Seller at
                  such subsequent time as is mutually acceptable to the
                  Buyer and the Seller, and as will be set forth in a
                  written agreement that will state the settlement agreed
                  by the Buyer and the Seller with respect to such defects.

8.1.5             Within three (3) months of execution of the Agreement,
                  the Buyer and the Seller will review the technical
                  documentation provided by the Seller at delivery of each
                  Aircraft, and, if practicable, will agree on any
                  reasonable changes to such documentation deemed necessary
                  by the Buyer.

8.2               Seller's Use of Aircraft

                  The Seller will be entitled to use, without compensation
                  to the Buyer, each Aircraft prior to its delivery as may
                  be necessary to obtain the certificates required under
                  Clause 2 hereof. Such use will not *** affect the Buyer's
                  obligation to accept delivery of any Aircraft hereunder.
                  *** All damage incurred in connection with the Seller's
                  use of the Aircraft will be repaired ***.

8.3               Certificate of Acceptance

                  When the Aircraft is "ready for delivery" as defined
                  below in Subclause 9.2, the Buyer will forthwith give to
                  the Seller a signed Certificate of Acceptance in the form
                  attached as Exhibit "E" in respect of the relevant
                  Aircraft. Should the Buyer fail to so deliver the said
                  Certificate, then the Buyer will be deemed to be in
                  default as though it had without warrant rejected
                  delivery of such Aircraft when duly tendered to it
                  hereunder and will thereafter bear all costs and expenses
                  resulting from such delay in delivery. The execution and
                  delivery of a Certificate of Acceptance by the Buyer in
                  respect of an Aircraft will not constitute waiver by the
                  Buyer of any rights and remedies it may have in respect
                  of any Aircraft under Clauses 12 and 13 of this
                  Agreement.

8.4               Finality of Acceptance

                  The Buyer's acceptance of delivery of each Aircraft will
                  constitute waiver by the Buyer of any right it may have
                  under the Uniform Commercial Code or otherwise to revoke
                  such acceptance for any reason, whether known or unknown
                  to the Buyer at the time of acceptance.

                  INJURY OR FOR PROPERTY DAMAGE, THE LIABILITY FOR WHICH
                  HAS BEEN ASSUMED BY THE OTHER PARTY PURSUANT TO THIS
                  SUBCLAUSE 8.5, THE FORMER (INDEMNITEE) WILL PROMPTLY GIVE
                  NOTICE TO THE OTHER PARTY (INDEMNITOR), AND THE

                  CONDUCT OF THE DEFENSE OF ANY CLAIM, ACTION, PROCEEDING
                  OR LAWSUIT INDEMNIFIED HEREUNDER.

10 -              EXCUSABLE DELAY

10.1              Scope

                  Neither the Seller nor the Manufacturer will be
                  responsible for or be deemed to be in default on account
                  of delays in delivery or failure to deliver or otherwise
                  in the performance of this Agreement or any part hereof
                  due to causes reasonably beyond the Seller's, the
                  Manufacturer's or any Associated Contractor's control or
                  not occasioned by the Seller's, the Manufacturer's or any
                  Associated Contractor's fault, misconduct or negligence
                  ("Excusable Delay").

                  It is expressly understood and agreed that each of (i)
                  any delay caused directly or indirectly by the Buyer's
                  failure to comply with its obligations hereunder, and
                  (ii) any delay in delivery or otherwise in the
                  performance of this Agreement by the Seller due in whole
                  or in part to any delay in or failure of the delivery of,
                  or any other event or circumstance relating to, the
                  Propulsion Systems or Buyer Furnished Equipment, will, to
                  the extent attributable to such delay, constitute
                  Excusable Delay for the Seller, unless such delay or
                  failure of delivery or other event or circumstance is
                  attributable to any default by the Seller of its
                  obligations hereunder or any failure of the Seller to
                  notify the Buyer and the manufacturer of the Propulsion
                  Systems in a timely manner of the Seller's need therefor.

                  The Seller will promptly after becoming aware of any
                  delay falling within the provisions of this Subclause
                  10.1 (i) notify the Buyer of such delay and of the
                  probable extent thereof, including, without limitation, a
                  description of the cause thereof and, if possible, a
                  possible date of rescheduled delivery in accordance with
                  the terms of this Agreement, and after such prompt
                  initial notice, apprise the Buyer of the status of such
                  delay and possible date of such rescheduled delivery, and
                  (ii) subject to the following provisions, as soon as
                  practicable after the removal of the cause or causes for
                  delay, resume the performance of those obligations
                  affected under this Agreement. The Seller and the
                  Manufacturer will endeavor to limit the extent of any
                  such delay. The Seller will schedule the delivery of the
                  Aircraft that is the subject of such delay to a date
                  compatible with the Aircraft delivery schedule of the
                  Buyer.

10.2              Unanticipated Delay

                  In the event that the delivery of any Aircraft will be
                  delayed by reason of an Excusable Delay for a period of
                  more than twelve (12) months after the end of the
                  calendar month in which delivery is otherwise required
                  hereunder, the Buyer will be entitled to terminate this
                  Agreement with respect only to the Aircraft so affected
                  upon written notice given to the Seller within thirty
                  (30) days after the expiration of such twelve (12) month
                  period. In the event such delay will continue for an
                  additional six (6) month period after the expiration of
                  such twelve (12) month period, either party will have the
                  option to terminate this Agreement with respect to the
                  Aircraft so affected upon written notice given to the
                  other within thirty (30) days after the end of such
                  additional six (6) month period. Any termination of this
                  Agreement in respect of an Aircraft pursuant to this
                  Subclause 10.2 will discharge all obligations and
                  liabilities of the parties hereunder with respect to such
                  affected Aircraft, ***.

10.3              Anticipated Delay

                  In respect of any Aircraft, the Seller may conclude that
                  Excusable Delays will (i) cause delay in delivery of such
                  Aircraft for a period of more than twelve (12) months
                  after the end of the calendar month in which delivery is
                  otherwise required or (ii) prevent delivery of such
                  Aircraft. In such event, in good faith and in accordance
                  with its normal scheduling procedures, the Seller will
                  give written notice to the Buyer of either (i) such delay
                  and its related rescheduling reflecting such delay(s) or
                  (ii) such nondelivery. Within thirty (30) days after the
                  Buyer's receipt of such notice, the Buyer may terminate
                  this Agreement as to such rescheduled or nondeliverable
                  Aircraft by giving written notice to the Seller. Such
                  termination will discharge all obligations and
                  liabilities of the parties hereunder with respect to such
                  affected Aircraft, ***.

10.4              Delivery Date

                  If, following notice of an anticipated delay under
                  Subclause 10.3, this Agreement is not terminated in
                  accordance with the provisions of Subclause 10.3 (with
                  respect to the affected Aircraft), then the date of
                  delivery otherwise required hereunder will be extended by
                  a period equal to the delay specified in such notice,
                  with a view towards having each Aircraft subject to such
                  Excusable Delay ready for delivery as promptly as
                  practicable. ***

10.5              Lost, Destroyed or Damaged Aircraft

10.5.1            If any Aircraft suffers a total loss, is destroyed, or is
                  damaged beyond economic repair prior to delivery thereof,
                  then this Agreement will be terminated with respect to
                  such Aircraft and the obligations and liabilities of the
                  parties hereunder with respect to such Aircraft will be
                  discharged. The Seller will repay to the Buyer an amount
                  equal to the entire amount of any Predelivery Payments
                  received from the Buyer hereunder with respect to any
                  such Aircraft that is lost, destroyed or damaged beyond
                  economic repair, ***.

10.5.2            If during the manufacturing process for any Aircraft or
                  at any other time prior to the delivery and performance
                  of any Aircraft, any Aircraft suffers damages in excess
                  of *** or is otherwise damaged in any material respect
                  (but not to the extent within the purview of Subclause
                  10.5.1), then the Seller will delivery a notice thereof
                  to the Buyer specifying the cause and nature thereof in
                  reasonable detail and how the Seller intends to cure the
                  same.

10.6              Equal Treatment

                  The Seller will use all reasonable efforts to ensure that
                  each Aircraft subject to an Excusable Delay is ***.

10.7              Additional Aircraft

                  In the event of termination of this Agreement in respect
                  of an Aircraft under Clause 10, the number of Additional
                  Aircraft will be increased by one unit. ***

10.8              REMEDIES

                  THIS CLAUSE 10 SETS FORTH THE SOLE AND EXCLUSIVE REMEDY
                  OF THE BUYER FOR DELAYS IN DELIVERY OR FAILURE TO

                  by Clause 10 or for circumstances specified in Subclause
                  11.6 ("Inexcusable Delay"), the Buyer will, in respect of
                  any subsequent delay in delivery of such Aircraft, have
                  the right to claim and the Seller will in respect of any

12.1              STANDARD WARRANTY

12.1.1            Nature of Warranty

                  Subject to the limitations and conditions as hereinafter
                  provided, and except as provided in Subclause 12.1.2, the
                  Seller warrants to the Buyer that each Aircraft and each
                  Warranted Part will at the time of delivery to the Buyer:

                  (i)      be free from defects in material,

                  (ii)     be free from defects in workmanship, including,
                           without limitation, processes of manufacture,

                  (iii)    be free from defects in design (including,
                           without limitation, selection of materials,
                           parts and components) having regard to the state
                           of the art at the date of such design,

                  (iv)     be free from defects arising from failure to
                           conform to the Specifications,

                  (v)      permit complete interchangeability among
                           Aircraft and parts of like part-numbered parts,
                           and

                  (vi)     be free and clear of all liens and other
                           encumbrances.

                  For the purposes of this Agreement, the term "Warranted
                  Part" will mean any Seller proprietary component,
                  equipment, accessory or part that at the time of delivery
                  of an Aircraft (a) is installed on or incorporated in

12.1.2            Exceptions

                  The warranties set forth in Subclause 12.1.1 will not
                  apply to Buyer Furnished Equipment, nor to engines, nor
                  to any component, accessory, equipment or part purchased
                  by the Buyer that is not a Warranted Part, provided,
                  however, that:

                  (i)      any defect in the Seller's workmanship in
                           respect of the installation of such items in or
                           on the Aircraft, including any failure by the
                           Seller to conform to the installation
                           instructions of the manufacturers of such items
                           that invalidates any applicable warranty from
                           such manufacturers, will constitute a defect in
                           workmanship for the purpose of this Subclause
                           12.1 and be covered by the warranty set forth in
                           Subclause 12.1.1(ii), and

                  (ii)     any defect inherent in the Seller's design of
                           the installation, in view of the state of the
                           art at the date of such design, that impairs the
                           use or function of such items will constitute a
                           defect in design for the purposes of this
                           Subclause 12.1 and be covered by the warranty
                           set forth in Subclause 12.1.1(iii).

12.1.3            Warranty Periods

                  The warranties described in Subclauses 12.1.1 and 12.1.2
                  herein above will be limited to those defects that become
                  apparent within thirty-six (36) months after delivery of
                  the affected Aircraft.

12.1.4            Buyer's Remedy and Seller's Obligation

12.1.4.1          The Buyer's remedy and the Seller's obligation and
                  liability under Subclauses 12.1.1 and 12.1.2 herein above
                  are limited to, at the Seller's expense, the repair,
                  replacement or correction of, or the supply of
                  modifications kits rectifying the defect for, any
                  defective Warranted Part, as mutually agreed between and
                  satisfactory to the Buyer and the Seller. *** Nothing
                  herein contained will obligate the Seller to correct any
                  failure to conform to the Specifications with respect to
                  components, equipment, accessories or parts that the
                  parties agree in writing at the time of delivery of the
                  affected Aircraft are acceptable deviations or have no
                  material adverse effect on the use, operation or
                  performance of an Aircraft.

                  If the Seller issues a Service Bulletin that requires ***
                  retrofit of equipment on a number of delivered Aircraft,
                  the Buyer can ***.

12.1.4.2          In the event a defect covered by Subclause 12.1.1 becomes
                  apparent within the period set forth in Subclause 12.1.3
                  and the Seller is obligated to correct such defect, the
                  Seller will also, if so requested by the Buyer in writing
                  and if reasonably practicable, make such correction in
                  any affected Aircraft that has not already been delivered
                  to the Buyer. Rather than accept a delay in delivery of
                  any such Aircraft, the Buyer and the Seller may agree to
                  deliver such Aircraft with subsequent correction of the
                  defect by the Buyer at the Seller's expense, or the Buyer
                  may elect to accept delivery and thereafter file a
                  Warranty Claim as though the defect had become apparent
                  immediately after delivery of such Aircraft.

12.1.4.3          In addition to the remedies set forth in Subclauses
                  12.1.4.1 and 12.1.4.2, the Seller will ***. The above
                  commitment is subject to the following conditions:

                  (i)      ***

                 (ii)      ***

                 (iii)      ***

12.1.5            Warranty Claim Requirements

                  The Buyer's remedy and the Seller's obligation and
                  liability under this Subclause 12.1, with respect to each
                  claimed defect, are subject to the following conditions
                  precedent:

                  (i)      the existence of a defect covered by the
                           provisions of this Subclause 12.1,

                  (ii)     the defect's having become apparent within the
                           applicable warranty period, as set forth in
                           Subclause 12.1.3,

                  (iii)    the Buyer's having returned as soon as
                           reasonably practicable the Warranted Part
                           claimed to be defective to such repair
                           facilities as may be designated by the Seller
                           *** except where the Buyer elects to repair a
                           defective Warranted Part in accordance with the
                           provisions of Subclause 12.1.7, and

                  administered as hereinafter provided:

                  (i)      Transportation Costs

                           Transportation costs associated with the sending
                           of a defective Warranted Part to the facilities
                           designated by the Seller and for the return
                           therefrom of a repaired or replacement Warranted
                           Part will be borne by the Buyer ***.

                  (ii)     Return of an Aircraft

                           In the event that the Buyer desires to return an
                           Aircraft to the Seller for consideration of a
                           Warranty Claim, the Buyer will notify the Seller
                           of its intention to do so and the Seller will,
                           prior to such return, have the right to inspect
                           such Aircraft and thereafter, without prejudice
                           to its rights hereunder, to repair such
                           Aircraft, at its sole option, either at the
                           Buyer's facilities, provided that space is
                           available, or at another mutually acceptable
                           location. Return of any Aircraft by the Buyer to
                           the Seller and return of such Aircraft to the
                           Buyer's facilities will be ***. The Buyer and

                  (iii)    On-Aircraft Work by the Seller

                           In the event that a defect subject to this
                           Subclause 12.1 may justify the dispatch by the
                           Seller of a working team to repair or correct
                           such defect at the Buyer's facilities, or in the
                           event of the Seller's accepting the return of an
                           Aircraft to perform or have performed such
                           repair or correction *** as determined in
                           accordance with in Subclause 12.1.7(v)(a).

                           If the Seller is requested to perform the work,
                           the Seller and the Buyer will agree on a
                           schedule and place for the work to be performed.

                  (iv)     Warranty Claim Substantiation

                           For each claim under this Subclause 12.1, the
                           Buyer will give written notice to the Seller
                           that contains at least the following data, to
                           the extent reasonably ascertainable, available
                           and relevant, with respect to a part or
                           Aircraft, as applicable ("Warranty Claim"). The
                           absence of data from any Warranty Claim will not
                           prejudice validity of such Warranty Claim. The
                           Buyer will endeavor to give the Seller such
                           Warranty Claim within *** of discovering the
                           defect giving rise to such Warranty Claim, but
                           in no event later than *** after such defect
                           becomes apparent.

                                    if any,

                           (b)      date of incident and/or of removal,

                           (c)      description of the defective part,

                           (d)      part number,

                           (e)      serial number (if applicable),

                                    in Clause 14 and Exhibit "F" hereto) as
                                    applicable,

                           (g)      total flying hours or calendar times,

                           (h)      time since last shop visit at the date
                                    of defect appearance,

                                    flight tests if flight tests prove
                                    necessary to complete a repair under
                                    the In-house Warranty) of the Warranted

                                    required for maintenance work
                                    concurrently being carried out on the

                                    above will be multiplied by an agreed
                                    labor rate representing the Buyer's
                                    composite average hourly labor rate
                                    (***, including all ***, social
                                    security charges, business taxes and
                                    similar items, but excluding fringe
                                    benefits) paid to the Buyer's employees
                                    whose jobs are directly related to the
                                    performance of the repair (the
                                    "In-house Warranty Labor Rate"). It is
                                    agreed that for the purpose hereof the
                                    In-house Labor Rate is ***.

                           (b)      Direct material costs are determined by
                                    the prices at which the Buyer acquired
                                    such replacement material, excluding
                                    any parts and materials used for
                                    overhaul furnished free of charge by
                                    the Seller.

                  (vi)     Limitation on Credit

                           The Buyer will in no event be credited for
                           repair costs (including labor and material) for
                           any Warranted Part exceeding sixty-five percent
                           (65%) of the Seller's current catalog price for
                           a replacement of such defective Warranted Part
                           or exceeding those costs which would have
                           resulted if repairs had been carried out at the
                           Seller's facilities.

                           Such cost will be substantiated in writing by
                           the Seller upon reasonable request by the Buyer.

                  (vii)    Scrapped Material

                           The Buyer will retain any Warranted Part
                           defective beyond economic repair and any
                           defective part removed from a Warranted Part
                           during repair for a period of either one hundred

                           completion of repair or ninety (90) days after
                           submission of a claim for In-house Warranty
                           credit relating thereto, whichever is longer.
                           Such parts will be returned to the Seller within
                           thirty (30) days of receipt of the Seller's
                           request to that effect, at the Seller's cost.

                           Notwithstanding the foregoing, the Buyer may,
                           with the agreement of the Seller's Field
                           Representative, scrap any such defective parts
                           that are beyond economic repair and not required
                           for technical evaluation.

                  (viii)   LIMITATIONS ON LIABILITY OF SELLER

                  The warranties provided for in this Subclause 12.1 for

                  owner, lessor, lessee or operator other than the Buyer,
                  if the Warranted Part enters into the possession of any

                  sale, transfer, lease or other conveyance or as a result
                  of a pooling or leasing agreement between such owner,
                  lessor, lessee or operator and the Buyer (and its

                  which the Seller is liable under Subclause 12.1 has been
                  corrected, repaired or replaced pursuant to the terms of

                  repair or replacement by the Buyer, a Warranty Claim with
                  respect to such defect will not be allowable,
                  notwithstanding any subsequent correction or repairs.

                  by any of the following, to:

                  (i)      any Aircraft or component, equipment, accessory
                           or part thereof that has been repaired, altered
                           or modified after delivery by a party other than

                  the cases of Subclause 12.1.10(i) and Subclause
                  12.1.10(ii) above only to the extent the Seller submits
                  sufficient evidence proving that the defect arose from or
                  was contributed to by either of said cases.

                  In addition to the warranties set forth in Subclause 12.1
                  above, the Seller further agrees that should a Failure

                           can reasonably be expected to occur in any other
                           Aircraft, and the Buyer will inform the Seller in

                           information available.

                  conditions of, Subclause 12.1.6.

12.3.1            Seller's Support

                  Prior to delivery of the first Aircraft, the Seller will
                  obtain from all Vendors listed in the Supplier Product
                  Support Agreements manual enforceable and transferable
                  warranties, service life policies, and indemnities
                  against patent infringements for Vendor Parts. The Seller
                  will also obtain enforceable and transferable Vendor
                  service life policies from landing gear Vendors for
                  selected structural landing gear elements. The Seller
                  undertakes to supply to the Buyer such Vendor warranties,
                  Vendor service life policies and indemnities against
                  patent infringements substantially in the form summarized
                  in the Supplier Product Support Agreements manual.

12.3.2            Vendor's Default

12.3.2.1          In the event that any Vendor under any standard warranty
                  or indemnity against patent infringements obtained by the
                  Seller pursuant to Subclause 12.3.1 or Clause 13 hereof
                  defaults in the performance of any material obligation
                  under such warranty or indemnity against patent
                  infringements with respect to a Vendor Part, and the
                  Buyer submits within a reasonable time to the Seller
                  reasonable evidence that such default has occurred, then
                  Subclause 12.1 or Clause 13 of this Agreement will apply
                  to the extent the same would have been applicable had
                  such Vendor Part been a Warranted Part except that, for
                  obligations covered under Subclause 12.1, the shorter of
                  (i) the Vendor's warranty period as indicated in the
                  Supplier Product Support Agreements manual and (ii) the
                  Seller's warranty period as indicated in Subclause 12.1.3
                  of this Agreement will apply.

                  life policy obtained by the Seller pursuant to Subclause
                  12.3.1 hereof defaults in the performance of any material
                  obligation with respect thereto, and the Buyer submits
                  within reasonable time to the Seller reasonable evidence
                  that such default has occurred, then Subclause 12.2 of
                  this Agreement will apply to the extent the same would
                  have been applicable had such component, equipment,
                  accessory or part been listed in Exhibit "D" hereto.

12.3.2.3          At the Seller's request, the Buyer will assign to the
                  Seller, and the Seller will be subrogated to, all of the
                  Buyer's rights against the relevant Vendor, with respect
                  to and arising by reason of such default and the Buyer
                  will provide reasonable assistance to enable the Seller
                  to enforce the rights so assigned.

12.4              INTERFACE COMMITMENT

12.4.1            Interface Problem

                  If the Buyer experiences any technical problem in the
                  operation of an Aircraft or its systems due to a
                  malfunction, the cause of which, after due and reasonable
                  investigation, is not readily identifiable by the Buyer,
                  but which the Buyer reasonably believes to be
                  attributable to the design characteristics of one or more
                  components of the Aircraft (an "Interface Problem"), the
                  Seller will, if requested by the Buyer, and without
                  additional charge to the Buyer, promptly conduct or have
                  conducted an investigation and analysis of such problem
                  to determine, if possible, the cause or causes of the
                  problem and to recommend such corrective action as may be
                  feasible. The Buyer will furnish to the Seller all data
                  and information in the Buyer's possession relevant to the
                  Interface Problem and will reasonably cooperate with the
                  Seller in the conduct of the Seller's investigations and
                  such tests as may be required.

                  At the conclusion of such investigation the Seller will
                  promptly advise the Buyer in writing of the Seller's
                  opinion as to the cause or causes of the Interface
                  Problem and the Seller's recommendations as to corrective
                  action.

12.4.2            Seller's Responsibility

                  If the Interface Problem is attributable to the design of
                  a Warranted Part, the Seller will, if requested by the
                  Buyer, take prompt action to correct the design of such
                  Warranted Part, pursuant to the terms and conditions of
                  Subclause 12.1 or 12.2, as applicable.

12.4.3            Vendor's Responsibility

                  If the Interface Problem is attributable to the design of
                  a component, equipment, accessory or part other than a
                  Warranted Part ("Vendor Component"), the Seller will, if
                  requested by the Buyer, promptly assist and cooperate
                  with the Buyer in processing and enforcing any warranty
                  claim the Buyer may have against the manufacturer of such
                  Vendor Component. Further, ***.

12.4.4            Joint Responsibility

                  If the Interface Problem is attributable partially to the
                  design of a Warranted Part and partially to the design of
                  any Vendor Component, the Seller will, if requested by
                  the Buyer, seek a solution to the Interface Problem
                  through cooperative efforts of the Seller and any Vendor
                  involved. The Seller will promptly advise the Buyer of
                  such corrective action as may be proposed by the Seller
                  and any such Vendor. Such proposal will be consistent
                  with any then existing obligations of the Seller
                  hereunder and of any such Vendor to the Buyer. When the
                  Seller or any Vendor has performed such corrective action
                  to the reasonable satisfaction of the Buyer, such
                  correction will constitute full satisfaction of any claim
                  the Buyer may have against either the Seller or any such
                  Vendor with respect to such Interface Problem.

12.4.5            All requests under this Subclause 12.4 will be directed
                  to the Seller.

12.5              Performance Standard

                  The Seller will take prompt action to perform its
                  obligations under this Clause 12. ***

                  GENERAL LIMITATIONS OF LIABILITY

                  THIS CLAUSE 12 (INCLUDING ITS SUBPROVISIONS AND RELATED

                  prior approval of the Buyer's payment, assumption or
                  admission of any liabilities, expenses, costs or
                  royalties for which the Seller is asked to respond and
                  (iv) the Buyer's not otherwise acting in a manner
                  prejudicial to its or the Seller's defense of the action.

                  Request for Publication Change ("Customer Originated
                  Changes" or "COC") may be introduced into the following

                  Technical Publications the COC data will be incorporated.
                  The customized Technical Publications into which the COC
                  data are incorporated will only show the Aircraft

                  incorporation of any COC into the Technical Publication
                  issued by or caused to be issued by the Seller will be

                  either the engineering contents of any COC, including any
                  omissions or inaccuracies therein, or the effect that
                  incorporation of such COC may have on the Technical
                  Publications.

14.5.3.6          The Seller will not be required to check any COC data
                  submitted for incorporation as aforementioned, and the
                  Buyer will ensure that all COC data submitted for
                  incorporation into a Technical Publication have received
                  prior approval from its local airworthiness authority.

14.5.3.7          IN THE EVENT THAT THE SELLER AND/OR THE MANUFACTURER IS
                  REQUIRED UNDER ANY COURT ORDER OR SETTLEMENT TO INDEMNIFY
                  IN WHOLE OR IN PART ANY THIRD PARTY FOR INJURY, LOSS OR

                  BUYER IS PROVIDED AN OPPORTUNITY TO ASSUME THE DEFENSE

                  OR ORAL COMMUNICATION THAT THE SELLER OR THE MANUFACTURER
                  MAY MAKE TO THE BUYER IN RESPECT OF SUCH DOCUMENTATION.

                  Buyer's personnel training described in this Clause 16
                  ("Training").

16.2              Course Organization and Administration

16.2.1            Location and Scheduling

                  In general, Training will be held either at the Airbus
                  Service Company Training Center, in Miami, Florida (the
                  "ATC-Miami"), or at the Airbus Training Center in
                  Toulouse, France (the "ATC-Toulouse"). Subject to
                  availability of training slots at the time and at the
                  selected location, the location of the Training will be
                  at the Buyer's choice. The Seller will ensure that the
                  Buyer's training plans (to be provided to the Seller
                  reasonably in advance of the delivery of Aircraft) are
                  implemented for a safe and smooth entry-into-service of
                  the Aircraft. However, certain Training courses may also
                  be held at the Buyer's base or other location, if
                  practicable, under terms and conditions to be mutually
                  agreed. The Buyer's training plans will include: (i)
                  just-in-time (determined on a reasonable basis) training
                  of flight crews, (ii) all necessary simulator time for
                  regular transition courses, and (iii) aircraft experience
                  for check pilots, and (iv) maintenance, dispatch and
                  flight attendant training.

                  Training courses will be scheduled for a minimum and
                  maximum number of participants, at dates mutually agreed
                  during a training conference to be held as soon as
                  practicable (the "Training Conference").

16.2.2            Course Content

                  Training courses will include features of the
                  Specifications required for training purposes, as known
                  at the latest six (6) months before the first Training
                  course starts. The Seller will endeavor to incorporate
                  training features that become known after the six-month
                  deadline. When the Seller does not provide maintenance or
                  flight attendant training on the Seller's approved Buyer
                  Furnished Equipment, the Seller will ensure that the
                  Buyer gets the relevant training support from the
                  supplier of the said equipment. Training courses will be
                  FAA approved "Transition Courses." The Seller will
                  provide the Buyer with A330/A340 differences training for
                  flight crew, maintenance, dispatch and/or flight
                  attendant personnel.

                  Training equipment used for flight and maintenance crew
                  training will reflect the Specifications as closely as
                  possible and will meet requirements to receive and
                  maintain the relevant FAA course approval. Maintenance
                  training will not assume prior knowledge of any Airbus
                  aircraft. The Seller will be responsible for all Training
                  course syllabi, training aids, equipment and materials.

                  The Seller will monitor Vendor compliance with support

                  will promptly take remedial action.

17.3              Vendor Part Repair Stations

17.3.1            The Manufacturer has developed with the Vendors a program

                  stations are listed in a document, the AOG and Repair
                  Guide, which is issued and regularly updated by the
                  Manufacturer.

                  The Seller undertakes that the Vendor Parts that have to
                  be forwarded for repair outside North America will be
                  sent back to the Buyer with proper tagging as required by
                  the FAA.

17.3.3            The Seller will support the Buyer in cases where the
                  agreed repair turn time of an approved repair station is
                  not met by causing free-of-charge loans or exchanges (as
                  specified in the relevant Supplier Product Support
                  Agreements manual) to be offered to the Buyer ***.

                  THIS AGREEMENT WILL BE GOVERNED BY AND CONSTRUED AND THE
                  PERFORMANCE THEREOF WILL BE DETERMINED IN ACCORDANCE WITH
                  THE LAWS OF THE STATE OF NEW YORK.

                  THE PARTIES HEREBY ALSO AGREE THAT THE UNITED NATIONS
                  CONVENTION ON THE INTERNATIONAL SALE OF GOODS WILL NOT
                  APPLY TO THIS TRANSACTION.

22.3.2            SUBMISSION TO JURISDICTION

                  EACH OF THE BUYER AND THE SELLER IRREVOCABLY AGREES THAT
                  ANY LEGAL ACTION OR PROCEEDING ARISING UNDER THIS
                  AGREEMENT MAY BE BROUGHT AND DETERMINED IN THE SUPREME
                  COURT OF THE STATE OF NEW YORK, NEW YORK COUNTY, IN THE
                  GENERAL DISTRICT COURTS OF FAIRFAX COUNTY OR ARLINGTON
                  COUNTY, VIRGINIA, OR IN THE UNITED STATES DISTRICT COURTS
                  FOR THE SOUTHERN DISTRICT OF NEW YORK, OR THE EASTERN
                  DISTRICT OF VIRGINIA AND IRREVOCABLY ACCEPTS WITH REGARD
                  TO ANY SUCH ACTION OR PROCEEDING THE NONEXCLUSIVE
                  JURISDICTION OF THOSE COURTS.

                  The Seller hereby irrevocably designates CT Corporation,
                  New York City offices, to receive for and on its behalf
                  service of process in any proceeding with respect to any
                  matter as to which it submits to jurisdiction as set
                  forth above, it being agreed that service upon CT
                  Corporation will constitute valid service upon the Seller

                  Agreement.

22.3.3            Waiver of Immunity

                  Agreement. The Seller hereby irrevocably waives, and
                  agrees not to assert, the defense of sovereign immunity,

                  action or proceeding is brought in an inconvenient forum,
                  that the venue of the action or proceeding is improper,
                  or that this Agreement may not be enforced in or by such
                  courts.

22.3.4            Dispute Resolution

                  ***

22.4              Confidentiality

                  Subject to any legal or governmental requirements of
                  disclosure, the parties (which for this purpose will
                  include their employees, agents and advisors) will
                  maintain the terms and conditions of this Agreement, any
                  reports or other data furnished, and other documents
                  furnished by the Seller hereunder strictly confidential.
                  Without limiting the generality of the foregoing, each
                  party will use its best efforts to limit the disclosure
                  of the contents of this Agreement to the extent legally
                  permissible in any filing required to be made by it with
                  any governmental agency and will make such applications
                  as will be necessary to implement the foregoing. With
                  respect to any public disclosure or filing, the
                  disclosing party agrees to submit to the other party a
                  copy of the proposed document to be filed or disclosed
                  and will give the other party a reasonable period of time
                  in which to review the said document. The Buyer and the
                  Seller will consult with each other prior to the making
                  of any public disclosure or filing, permitted hereunder,
                  of this Agreement or the terms and conditions thereof.
                  The provisions of this Subclause 22.4 will survive any
                  termination of this Agreement.

22.5              Severability

                  In the event that any provision of this Agreement should
                  for any reason be held to be without effect, the
                  remainder of this Agreement will remain in full force and
                  effect. To the extent permitted by applicable law, each
                  party hereto hereby waives any provision of law which
                  renders any provision of this Agreement prohibited or
                  unenforceable in any respect.

22.6              Alterations to Contract

                  This Agreement, including its Exhibits, Appendixes and
                  Letter Agreements, contains the entire agreement between
                  the parties with respect to the subject matter hereof and
                  thereof and supersedes any previous understanding,
                  commitments or representations whatsoever, whether oral
                  or written (including, without limitation, that certain

                  5211.9), between the Seller and the Buyer and all letter
                  agreements ancillary thereto). This Agreement will not be
                  varied except by an instrument in writing of even date
                  herewith or subsequent hereto executed by both parties or
                  by their fully authorized representatives.

22.7              Inconsistencies

                  In the event of any inconsistency between the terms of
                  this Agreement and the terms contained in either (i) the
                  Specifications, or (ii) any other Exhibit or Letter
                  Agreement attached to this Agreement, in each such case
                  the terms of such Specifications, Exhibit or Letter
                  Agreement will prevail over the terms of this Agreement.
                  For the purpose of this Subclause 22.7, the term
                  Agreement will not include the Specifications or any
                  other Exhibit or Letter Agreement hereto.

22.8              Language

                  All correspondence, documents and any other written
                  matters in connection with this Agreement will be in

22.9              Headings

                  All headings in this Agreement are for convenience of
                  reference only and do not constitute a part of this
                  Agreement.

22.10             Counterparts

                  This Agreement may be executed by the parties hereto in
                  separate counterparts, each of which when so executed and
                  delivered will be an original, but all such counterparts
                  will together constitute but one and the same instrument.

IN WITNESS WHEREOF, these presents were entered into as of the day and year

made in accordance with Clause 19 thereof. The Guarantor further agrees
that it will execute and deliver such other and further instruments as may

and of payment, and the Guarantor agrees that, in case of default by the
Seller, the Buyer will not be required to file suit against the Seller as a

Arlington County, Virginia, in the United States District Courts for the
Southern District of New York or the Eastern District of Virginia, or in
the commercial Court ("Tribunal de Commerce") of Toulouse, France, and
irrevocably accepts with regard to any such action or proceeding the
nonexclusive jurisdiction of those courts. The Guarantor irrevocably waives
the benefit of Articles 14 and 15 of the French Civil Code. The Guarantor
hereby irrevocably waives, and agrees not to assert, the defense of
sovereign immunity, and, to the extent permitted by law, the defense that
the action or proceeding is brought in an inconvenient forum, that the
venue of the action or proceeding is improper, or that this Consent and
Guaranty may not be enforced in or by such courts. However, the preceding
sentence will not be construed as a waiver of any requirement of service of
process. The Guarantor hereby irrevocably designates CT Corporation as the
Guarantor's agent to receive service of process in any legal action or
proceeding with respect to this Consent and Guaranty.

                              LICENSE FOR USE
               OF THE PERFORMANCE ENGINEERING PROGRAMS (PEP)


1.       GRANT

         The Seller grants to the Buyer the right to use the Performance
         Engineering Programs (PEP) in machine readable form on a single
         computer during the term of this license agreement (the "License
         Agreement").

         Use of the PEP in readable form will be limited to one (1) copy.
         However, the Seller may make duplicate copies, provided that they
         are either contained in the same computer as the original copy, or
         produced for checkpoint and restart purposes or made with the
         consent of the Seller for a specific need.

2.       MERGING

         The PEP may be used and adapted in machine readable form for the
         purpose of merging it into other program material of the Buyer,
         but, on termination of this License Agreement, the Buyer will
         remove the PEP from the other program material with which it has
         been merged.

         The Buyer agrees to reproduce the copyright and other notices as
         they appear on or within the original media on any copies that the
         Buyer makes of the PEP.

3.       PERSONAL LICENSE

         The above described license is personal to the Buyer,
         nontransferable and nonexclusive.

4.       INSTALLATION

         It is the Buyer's responsibility to install the PEP and to perform
         any mergings and checks. The Seller will, however, assist the
         Buyer's operations engineers in the initial phase following the
         delivery of the PEP until such personnel reach the familiarization
         level required to make inputs and correlate outputs.

5.       PROPRIETARY RIGHTS AND NONDISCLOSURE

5.1      The PEP and the copyright and other proprietary rights of whatever
         nature in the PEP are and will remain with the Seller. The PEP and
         its contents are designated as confidential.

5.2      The Buyer undertakes not to disclose the PEP, parts thereof or its
         contents to any third party without the prior written consent of
         the Seller. Insofar as it is necessary to disclose aspects of the
         PEP to employees, such disclosure is permitted only for the
         purpose for which the PEP is supplied and only to the employee who
         needs to know the same.

6.       CONDITIONS OF USE

6.1      The Seller does not warrant that the PEP will contain no errors.
         However, should the PEP be found to contain any error at delivery,
         the Buyer will notify the Seller promptly thereof and the Seller
         will take all proper steps to correct the same at its own expense.

6.2      The Buyer will ensure that the PEP is correctly used in
         appropriate machines as indicated in the Performance Programs
         Manual (PPM) and that staff are properly trained to use the same,
         to trace and correct running faults, to restart and recover after
         fault and to operate suitable checks for accuracy of input and
         output.

6.3      It is understood that the PPM is the user's guide of the PEP and
         that the Buyer will undertake to use the PEP in accordance with
         the PPM.

6.4      The PEP is supplied under the express condition that the Seller
         will have no liability in contract or in tort arising from or in
         connection with the Buyer's use of or inability to use the PEP.

7.       DURATION

         Subject to the Buyer's compliance with the terms of this License
         Agreement, the rights under this License Agreement will be granted
         to the Buyer for as long as the Buyer operates an Aircraft to

         The Base Price of the Airframe is as quoted in Subclause 4.1.1.1,
         4.1.1.2, 4.1.1.3 or 4.1.1.4 of the Agreement, as applicable.

2.       BASE PERIOD

         ***

         These Base Prices are subject to adjustment for changes in
         economic conditions as measured by data obtained from the United
         States Department of Labor, Bureau of Labor Statistics, and in
         accordance with the provisions of Paragraphs 4 and 5 of this
         Exhibit "G."

         Should the Bureau of Labor Statistics change the base year
         indicated below in Paragraph 3, it will be necessary to restate
         such values in an appropriate manner. Other changes (such as
         benchmark revision), except those related to established errors
         from the Bureau of Labor Statistics, will not be taken into
         consideration.

3.       REFERENCE INDEXES

         ***

         Material Index:  "Industrial Commodities Index" (hereinafter 
         referred to as "ICI-Index"), published monthly by the United 
         States Department of Labor, Bureau of Labor Statistics, in 
         "Producer Prices and Price Indexes" (Table 6: "Producer prices
         and price indexes for commodity groupings and individual items").
         (Base year 1982 = 100.) 

4 -      REVISION FORMULA

         ***

         In determining the Revised Base Price at delivery of the Aircraft,
         each quotient will be calculated to the nearest ten thousandth (4
         decimals). If the next succeeding place is five (5) or more, the
         preceding decimal place will be raised to the next higher figure.
         The final factor will be rounded to the nearest ten thousandth (4
         decimals).

         After final computation, Pn will be rounded to the next whole
         number (0.5 or more rounded to l).

5.       GENERAL PROVISIONS

5.1      Substitution of Indexes

         In the event that:

         (i)      the United States Department of Labor substantially
                  revises its methodology for calculating any of the
                  indexes referred to here above, or

         (ii)     the United States Department of Labor discontinues,
                  either temporarily or permanently, any of the indexes
                  referred to here above and publication thereof, or

         (iii)    the data samples used to calculate any of the indexes
                  referred to here above are substantially changed,

         The Seller and the Buyer will agree on a substitute index.

         Such substitute index will reflect as closely as possible the
         actual variations in wage rates or in material prices, as the case
         may be, used in the calculation of the original index.

         As a result of this selection of a substitute index, the Seller
         and the Buyer will agree on appropriate adjustments to be made to
         the price revision formula; such adjustments may include, but will
         not be limited to, allowing to combine the successive utilization
         of the original index and of the substitute index, and other
         methodologies designed to ensure consistency in the numerators and
         denominators of the various quotients.

5.2      Final Index Values

         The Revised Base Price at the date of Aircraft delivery will be
         final and will not be subject to further adjustments, of any kind,
         to the applicable indexes as published at the date of Aircraft
         delivery.



                                                              EXHIBIT "H-1"

         in no event be less than the Reference Price defined in Paragraph
         1 of this Exhibit "H-1."

5.3      If no final index value is available for any of the applicable
         months, the published preliminary figures will be the basis on
         which the Revised Reference Price will be computed.

5.4      If the US Department of Labor substantially revises the
         methodology of calculation of the indexes referred to in this
         Exhibit "H-1" or discontinues any of these indexes, the Seller
         will, in agreement with Pratt & Whitney, apply a substitute for
         the revised or discontinued index, such substitute index to lead
         in application to the same adjustment result, insofar as possible,
         as would have been achieved by continuing the use of the original
         index as it may have fluctuated had it not been revised or
         discontinued.

         Appropriate revision of the formula will be made to accomplish
         this result.

5.5      Should the above escalation provisions become null and void by
         action of the US Government, the Reference Price will be adjusted
         to reflect increases in the cost of labor, material and fuel which

1.2.3             During a period commencing on the date hereof and
                  continuing as long as at least five (5) aircraft of the

                  commercial air transport service (the "Term"), the Seller
                  will maintain or cause to be maintained such stock of
                  Seller Parts as the Seller deems reasonable (upon
                  consultation with the Buyer) and will furnish Seller
                  Parts adequate to meet the Buyer's needs for repairs and

                  not in any way prevent the Buyer from resorting to the
                  stocks of Seller Parts of other airlines operating
                  aircraft of the type of the Aircraft or from purchasing
                  items equivalent to Seller Parts from said airlines,
                  distributors or dealers, on the condition that said
                  Seller Parts have been designed and manufactured by, or

                  The period up to and expiring on the ninetieth (90th) day
                  after delivery of the last Aircraft subject to firm order
                  under the Agreement will hereinafter be referred to as
                  the Initial Provisioning Period.

2.1               Seller-Supplied Data

                  The Seller will prepare and supply to the Buyer the
                  following documents:

2.1.1             Initial Provisioning Data

                  The Seller will provide the Buyer initial provisioning
                  data provided for in Chapter 1 of ATA 2000 for the
                  Aircraft ("Initial Provisioning Data") in a form, format
                  and within a time period to be mutually agreed upon.

                  A revision service will be provided free of charge and
                  will be effected every ninety (90) days or more
                  frequently if reasonably requested by the Buyer, up to
                  the end of the Initial Provisioning Period, or until the
                  configuration of the Buyer's delivered Aircraft is
                  included.

                  In any event, the Seller will ensure that Initial
                  Provisioning Data are released to the Buyer in time to
                  allow the necessary evaluation time by the Buyer and the
                  on-time delivery of ordered Material.

2.1.2             Supplementary Data

                  The Seller will provide the Buyer with Local Manufacture
                  Tables (X-File), as part of the Illustrated Parts Catalog
                  (Additional Cross-Reference Tables), which will be a part
                  of the Initial Provisioning Data Package.

2.1.3             Initial Provisioning Data for Reconfirmable Aircraft

2.1.3.1           All Reconfirmable Aircraft and Additional Aircraft which
                  are acquired by the Buyer (the "Reconfirmed Aircraft")
                  pursuant to the terms and conditions of Letter Agreement
                  No. 2 to the Agreement will be included in the revision
                  to the provisioning data that is issued after
                  reconfirmation of a Reconfirmable Aircraft or the Buyer's
                  exercise of its option to purchase an Additional
                  Aircraft, if such revision is not scheduled to be issued
                  within four (4) weeks from the date of reconfirmation or
                  of the date of exercise of such option. If the date of
                  reconfirmation or the date of the exercise of the option
                  does not allow the Seller four (4) weeks' preparation
                  time, the Aircraft concerned will be included in the next
                  scheduled revision.

2.1.3.2           The Seller will, from the date of reconfirmation of an
                  Aircraft until three (3) months after delivery of such
                  Aircraft, submit to the Buyer details of particular
                  Vendor components being installed on the Aircraft and
                  will recommend the quantity to order. A list of such
                  Vendor components will be supplied at the time of the
                  provisioning data revision as specified above.

2.1.3.3           The Seller will deliver to the Buyer T-files for
                  particular Vendor components, as applicable, in time to
                  allow the Buyer's planning of repair and overhaul tasks.

2.1.3.4           At delivery of each Reconfirmed Aircraft, the data with
                  respect to Material will at least cover such Aircraft's
                  technical configuration as known six (6) months before
                  Aircraft delivery and will be updated to reflect the
                  final build status of such Aircraft. Such update will be
                  included in the data revisions issued three (3) months
                  after delivery of such Aircraft.

2.2               Vendor-Supplied Data

2.2.1             General

                  Vendors will prepare and issue T-files in the English
                  language for those Vendor components for which the Buyer
                  has elected to receive data.

                  Said data (initial issue and revisions) will be
                  transmitted to the Buyer through the Seller. The Seller
                  will review the compliance of such data with relevant ATA
                  requirements, but will not be responsible for the
                  substance of such data, other than any errors or
                  omissions attributable to the Seller's compilation of the
                  data. The Seller will use its best efforts to ensure that
                  such data will be adequate to enable the Buyer to
                  undertake in-house repair and/or overhaul of such
                  components.

                  In any event, the Seller will exert its best efforts to
                  supply Initial Provisioning Data to the Buyer in time to
                  allow the necessary evaluations by the Buyer and on-time
                  deliveries.

2.2.2             Initial Provisioning Data

                  Initial Provisioning Data for Vendor products provided
                  for in Chapter 1 of ATA 2000 for the Aircraft will be
                  furnished as mutually agreed upon during a
                  Preprovisioning Meeting (defined below), with
                  free-of-charge revision service assured up to the end of
                  the Initial Provisioning Period, or until it reflects the
                  configuration of the delivered Aircraft.

2.3               Preprovisioning Meeting

2.3.1             The Seller will organize a meeting at its Material
                  Support Center in Hamburg, Germany ("MSC"), to formulate
                  an acceptable schedule and working procedure to
                  accomplish the Initial Provisioning of Material (the
                  "Preprovisioning Meeting").

2.3.2             The date and location of the Preprovisioning Meeting will
                  be mutually agreed upon.

2.4               Initial Provisioning Training

                  The Seller will furnish, at the Buyer's request and at no
                  charge, training courses related to the Seller's
                  provisioning documents, purchase order administration and
                  handling at MSC.

2.5               Initial Provisioning Conference

                  The Seller will organize an Initial Provisioning
                  conference at MSC that will include Vendor participation,
                  as agreed upon during the Preprovisioning Meeting (the
                  "Initial Provisioning Conference").

2.6               Initial Provisioning Data Compliance

2.6.1             Initial Provisioning Data generated by the Seller and
                  supplied to the Buyer will comply with the latest
                  configuration of the Aircraft to which such data relate,
                  as known three (3) months before the data are issued.
                  Said data will enable the Buyer to order Material
                  conforming to its Aircraft as required for maintenance
                  and overhaul.

                  This provision will not cover parts embodying those Buyer
                  modifications that are unknown to the Seller, and parts
                  embodying modifications neither agreed to nor designed by
                  the Seller.

2.6.2             During the Initial Provisioning Period, Material will
                  conform with the latest configuration standard of the
                  affected Aircraft and with the Initial Provisioning Data
                  transmitted by the Seller. Should the Seller default in
                  this obligation, it will immediately replace such parts
                  and/or authorize return shipment at no transportation
                  cost to the Buyer. The Buyer will make reasonable efforts
                  to minimize such cost, in particular by using its own
                  airfreight system for transportation *** at no charge to
                  the Seller, ***. The Seller, in addition, will use its
                  best efforts to cause Vendors to provide a similar
                  service for their items.

2.7               Delivery of Initial Provisioning Material

2.7.1             To support the operation of the Aircraft, the Seller will

                  connection therewith to the extent that such cost has

                           order from the Buyer.

                  previously placed by the Buyer or upon requests by
                  telephone or telex by the Buyer's representatives, such

                  Subclause 10.1 of the Agreement will apply to the
                  Material Support as defined in Paragraph 1 of this Letter
                  Agreement.

4.5               Shortages, Overshipments, Nonconformance in Orders

4.5.1             Within thirty (30) days after receipt of Material
                  delivered pursuant to a purchase order, the Buyer will
                  use all best efforts to advise the Seller of any alleged
                  shortages or overshipments with respect to such order and
                  of all nonconformance to specification of parts in such
                  order inspected by the Buyer.

                  In the event that the Buyer has not reported such alleged
                  shortages, overshipments or nonconformance within the
                  above defined period, the Buyer will be deemed to have
                  accepted the deliveries unless the Buyer can prove within
                  a reasonable period of time that it did not receive the
                  Material.

4.5.2             In the event that the Buyer reports overshipments or
                  nonconformance to the specifications within the period
                  defined above in Subparagraph 4.5.1, the Seller will, if
                  accepted, either replace the Material concerned or credit
                  the Buyer for Material returned. In such case,
                  transportation charges will be borne by the Seller.

                  The Buyer will endeavor to minimize such costs,
                  particularly by using its own airfreight system on a
                  space-available basis for transportation at no charge to
                  the Seller.

4.6               Delivery Performance of Material

                  The Seller hereby agrees to participate in a Material
                  delivery performance incentive.

                  Based upon the Material delivery performance criteria for
                  response under Expedite Service as set forth in
                  Subparagraph 4.2.3 and for routine orders in accordance
                  with the Seller's published lead times, and provided all
                  above shipments *** (the "Delivery Criteria"), the Seller
                  commits to an overall delivery performance of eighty-five
                  percent (85%) on an annual basis. In the event that the
                  Seller's performance falls below the eighty-five percent
                  (85%) level, the Seller will provide the Buyer with a
                  credit equal to (i) eighty-five (85%) minus the actual
                  percentage of orders delivered on time, up to a maximum
                  of ten percent (10%), multiplied by (ii) the aggregate
                  value of the orders delivered late according to the
                  Delivery Criteria set forth above. Subparagraph 4.4 above
                  will apply to the Seller's undertakings under this
                  Subparagraph 4.6.

                  At the end of each year following delivery of the first
                  Aircraft, the Seller will compute the above-described
                  figures in order to determine a credit or debit for the
                  account of the Buyer.

                  In the event the Seller records a credit for the account
                  of the Buyer, the Seller will make available to the Buyer
                  a credit memorandum in the amount described in this
                  Subparagraph 4.6 for the purchase of Material from the
                  Seller.

4.7               Exclusivity of Remedy

                  The remedies provided to the Buyer under Subparagraphs
                  2.7.2 and 4.6 above are mutually exclusive and not
                  cumulative.

4.8               Cessation of Deliveries

                  The Seller reserves the right to stop or otherwise
                  suspend deliveries of Material if the Buyer fails to meet
                  its obligations under Paragraphs 6 and 7 of this Letter
                  Agreement.

                  the date of receipt of the order (subject to reasonable
                  quantities and delivery time) and will be expressed in US
                  dollars. Payment will be made by the Buyer to the Seller
                  in US dollars as set forth below in Subparagraph 6.1.

                  then current Seller's Spare Parts Price List. Prices will
                  be firm for each calendar year. The Seller, however,
                  reserves the right to revise the prices of Seller Parts
                  during the course of the calendar year in the event of
                  manifest error in estimation or expression of any price.

                  In the event of a significant revision in manufacturing
                  costs or a significant revision in the purchase price to
                  the Manufacturer of Seller Parts (including significant
                  variation in exchange rate) during any particular
                  calendar year, the Seller will notify the Buyer of such
                  revisions, whereupon the Buyer may, within such
                  quantities of affected Seller Parts still available for
                  sale at the former prices, order such quantities of said
                  Seller Parts reasonably required to maintain its
                  customary stock levels of such Seller Parts for the
                  remainder of the calendar year in effect at that time
                  provided the Seller is not thereby required to deplete
                  the Seller's AOG inventory level unless such Seller Parts
                  are required by the Buyer on an AOG basis. In the event
                  the Seller is out of stock of such Seller Parts at the
                  former prices, the Seller will, upon request by the
                  Buyer, reasonably substantiate the price revisions
                  affecting such Seller Parts.

                  percent (15%). This average handling charge will be
                  increased to eighteen percent (18%) in the event that all
                  orders have not been placed nine (9) months prior to

                  facility of the Leased Part in a serviceable condition.
                  The Lease Term will not exceed ninety (90) days after the
                  Lessee's receipt of the Leased Part, unless extended by
                  written agreement between Lessor and Lessee within such
                  ninety (90)-day period (such extension not to exceed an
                  additional ninety (90) days). Notwithstanding the
                  foregoing, the Lease Term will end in the event, and upon
                  the date, of exercise of the Lessee's option to purchase
                  the Leased Part, as provided herein.

12.4              Lease Charges and Taxes

                  The Lessee will pay the Lessor (a) a daily rental charge
                  for the Lease Term in respect of each Leased Part equal
                  to one-three-hundred-sixty-fifth (1/365) of the Catalog
                  Price of such Leased Part, as set forth in the Seller's
                  Spare Parts Price List in effect on the date of
                  commencement of the Lease Term, (b) any reasonable
                  additional costs which may be incurred by the Lessor
                  solely and directly as a result of such Lease, such as
                  inspection, test, repair, overhaul and repackaging costs
                  as required to place the Leased Part in serviceable
                  condition, (c) all transportation and insurance charges
                  and (d) any taxes (excluding any taxes based on income or
                  gross receipts), charges or customs duties imposed upon
                  the Lessor or its property as a result of the lease,
                  sale, delivery, storage or transfer of any Leased Part
                  (the "Lease Charges"). All payments due hereunder will be
                  made in accordance with Paragraph 6 of this Letter
                  Agreement.

                  In the event that the Leased Part has not been returned
                  to the Lessor's designated facilities within the time
                  period provided in Subparagraph 12.3 above, the Lessor
                  will be entitled, in addition to any other remedy it may
                  have at law or under this Paragraph 12, to charge to the
                  Lessee, and the Lessee will pay, all of the charges
                  referred to in this Subparagraph 12.4 accruing for each
                  day after the end of the Lease Term and for as long as
                  such Leased Part is not returned to the Lessor and as
                  though the Lease Term were extended to the period of such
                  delay.

                  Notwithstanding the foregoing, the Lessor hereby agrees
                  not to charge the Lessee any daily rental charge as
                  referred to above in Subparagraph 12.4(a) from the date
                  that is ninety (90) days after the date of receipt of the
                  Leased Part by the Lessee, provided that (i) the Lessee
                  reasonably demonstrates that the repair station
                  designated by the Lessor and to which the Lessee has sent
                  the damaged item (which is the cause of the lease
                  described in this Paragraph 12) (the "Damaged Item") has
                  failed to perform the repair of the Damaged Item within
                  ninety (90) days, and (ii) the repair station is unable
                  to provide adequate and satisfactory reasons for its
                  nonperformance.

12.5              Title

                  Title to each Leased Part will remain with the Lessor at
                  all times unless the Lessee exercises its option to
                  purchase or exchange it in accordance with Subparagraph
                  12.8 of this Letter Agreement, in which case title will
                  pass to the Lessee in accordance with Paragraph 7 of this
                  Letter Agreement.

12.6              Risk of Loss

                  Except for normal wear and tear, each Leased Part will be
                  returned to the Lessor in the same condition as when
                  delivered to the Lessee. However, the Lessee will not
                  without the Lessor's prior written consent repair, modify
                  or alter any Leased Part (other than routine
                  maintenance). Risk of loss or damage to each Leased Part
                  will remain with the Lessee until such Leased Part is
                  redelivered to the Lessor at the return location
                  specified in the applicable Lease. If a Leased Part is
                  lost or damaged beyond repair, the Lessee will be deemed
                  to have exercised its option to purchase the part in
                  accordance with Subparagraph 12.8 of this Letter
                  Agreement, as of the date of such loss or damage.

12.7              Record of Flight Hours

                  All flight hours accumulated by the Lessee on each Leased
                  Part during the Lease Term will be documented by the
                  Lessee. Records will be delivered to the Lessor upon
                  return of such Leased Part to the Lessor. In addition,
                  all documentation pertinent to inspection, maintenance
                  and/or rework of the Leased Part to maintain said Leased
                  Part serviceable in accordance with the standards of the
                  Lessor will be delivered to the Lessor upon return of the
                  Leased Part to the Lessor on termination of the Lease.

                  Such documentation will include but not be limited to
                  evidence of incidents such as hard landings,
                  abnormalities of operation and corrective action taken by
                  the Lessee as a result of such incidents.

12.8              Option to Purchase

                  The Lessee may at its option, exercisable by written
                  notice given to the Lessor, elect during or at the end of
                  the Lease Term to purchase the Leased Part, in which case
                  the then current purchase price for such Leased Part as
                  set forth in the Seller's Spare Parts Price List will be
                  paid by the Lessee to the Lessor. The immediately
                  preceding sentence will apply to new Leased Parts only.
                  In the event the Leased Part is not new at commencement
                  of the Lease Term, eighty-five percent (85%) of the then
                  current purchase price for such Leased Part will be paid
                  by the Lessee to the Lessor. Such option will be
                  contingent upon the Lessee providing the Lessor with
                  evidence satisfactory to the Lessor that the original
                  part fitted to the Aircraft is beyond economical repair.
                  Should the Lessee exercise such option, *** of the Lease
                  rental charges already invoiced pursuant to Subparagraph
                  12.4 (a) will be credited to the Lessee against the said
                  purchase price of the Leased Part.

                  Should the Lessee fail to return the Leased Part to the
                  Lessor at the end of the Lease Term, such failure will be
                  deemed to be an election by the Lessee to purchase the
                  Leased Part.

                  In the event of purchase, the Leased Part will be
                  warranted in accordance with Clause 11 of this Letter
                  Agreement as though such Leased Part were a Seller Part,
                  provided, however, that (i) the Seller will prorate the
                  full Warranty Period granted to the Buyer according to
                  the actual usage of such Leased Part and (ii) in no event
                  will such Warranty Period be less than six (6) months
                  from the date of purchase of such Leased Part. A warranty
                  granted under this Subparagraph 12.8.3 will be in
                  substitution for the warranty granted under Subparagraph
                  12.9 at the commencement of the Lease Term.

12.9              Warranties

                  The Lessor, in its capacity as "Lessee," under its
                  arrangements with the Manufacturer, in its capacity as
                  "Lessor," has negotiated and obtained the following
                  warranties from the Manufacturer with respect to the
                  Leased Parts, subject to the terms, conditions,
                  limitations and restrictions all as hereinafter set out.
                  The Lessor hereby assigns to the Lessee, and the Lessee
                  hereby accepts, all of the rights and obligations of the
                  Lessor in the Lessors's capacity as "Lessee" as aforesaid
                  under the said warranties and the Lessor subrogates the
                  Lessee as to all such rights and obligations in respect
                  of Leased Parts during the Lease Term with respect
                  thereto. The Lessor hereby warrants to the Lessee that
                  the Lessor has all requisite authority to make the
                  foregoing assignment and effect the foregoing subrogation
                  to and in favor of the Lessee and that the Lessor will
                  not enter into any amendment of the provisions so
                  assigned or subrogated without the prior written consent
                  of the Lessee. Capitalized terms utilized in the
                  following provisions have the meanings assigned thereto
                  in this Letter Agreement, except that the term "Lessor"
                  refers to the Manufacturer and the term "Lessee" refers
                  to the Lessor. References to clauses and paragraphs in
                  the following provisions refer to clauses in the
                  Agreement and/or to paragraphs in this Letter Agreement.

12.9.1            The Lessor warrants that each Leased Part will at the
                  time of delivery thereof:

                  (a)      be free from defects in material,

                  (b)      be free from defects in workmanship, including,

                           date of such design,

                  (e)      permit complete interchangeability among
                           Aircraft and parts of like part-numbered parts,
                           and

                  (f)      be free and clear of all liens and other
                           encumbrances.

12.9.2            Survival of Warranties

                  With respect to each Leased Part, the warranty set forth
                  above in Subparagraph 12.9.1(a) will not survive
                  delivery, and the warranties set forth above in
                  Subparagraphs 12.9.1(b) through 12.9.1(f) will survive
                  delivery only upon the conditions and subject to the
                  limitations set forth below in Subparagraphs 12.9.3
                  through 12.9.8.

12.9.3            Warranty and Notice Periods

                  The Lessee's remedy and the Lessor's obligation and
                  liability under this Subparagraph 12.9, with respect to
                  each defect, are conditioned upon (i) the defect having
                  become apparent within the Lease Term and (ii) the
                  Lessor's warranty administrator having received written
                  notice of the defect from the Lessee within *** of
                  discovering the defect giving rise to a warranty claim
                  under this Subparagraph 12.9, but in no event later than
                  *** after such defect becomes apparent.

12.9.4            Return and Proof

                  The Lessee's remedy and the Lessor's obligation and
                  liability under this Subparagraph 12.9, with respect to
                  each defect, are also conditioned upon:

                  (a)      the return by the Lessee as soon as practicable
                           to the return location specified in the
                           applicable Lease, or such other place as may be
                           mutually agreeable, of the Leased Part claimed
                           to be defective, and

                  (b)      the submission by the Lessee to the Lessor's
                           warranty administrator of reasonable proof that
                           the claimed defect is due to a matter embraced
                           within the Lessor's warranty under this
                           Subparagraph 12.9 and that such defect did not
                           result from any act or omission of the Lessee,
                           including but not limited to any failure to
                           operate or maintain the Leased Part claimed to
                           be defective or the Aircraft in which it was
                           installed in accordance with the Lessee's
                           FAA-approved maintenance program.

12.9.5            Remedies

                  The Lessee's remedy and the Lessor's obligation and
                  liability under this Subparagraph 12.9 with respect to
                  each defect are limited to the repair of such defect in
                  the Leased Part in which the defect appears, or, as
                  mutually agreed, to the replacement of such Leased Part
                  with a similar part free from defect.

                  Any replacement part furnished under this Subparagraph
                  12.9.5 will for the purposes of this Letter Agreement be
                  deemed to be the Leased Part so replaced.

12.9.6            Suspension and Transportation Costs

12.9.6.1          If a Leased Part is found to be defective and is covered
                  by this warranty, the Lease Term and the Lessee's
                  obligation to pay rental charges as provided in
                  Subparagraph 12.4(a) of this Letter Agreement will be
                  suspended from the date on which the Lessee notifies the
                  Lessor of such defect until the date on which the Lessor
                  has repaired, corrected or replaced the defective Leased
                  Part, provided, however, that the Lessee has withdrawn
                  such defective Leased Part from use, promptly after
                  giving such notice to the Lessor. If the defective Leased
                  Part is replaced, such replacement will be deemed to no
                  longer be a Leased Part under the Lease as of the date on
                  which such part was received by the Lessor at the return
                  location specified in the applicable Lease.

                  If a Leased Part is found to be defective on first use by
                  the Lessee and is covered by this warranty, no rental or
                  other charges as provided in Subparagraph 12.4(a) will
                  accrue and be payable by the Lessee until the date on
                  which the Lessor has repaired, corrected or replaced the
                  defective Leased Part in a manner satisfactory to the
                  Lessee.

12.9.6.2          All transportation and insurance costs associated with
                  the return of the defective Leased Part to the Lessor and
                  the return of the repaired, corrected or replacement part
                  to the Lessee will be borne by the Lessor.

12.9.7            Wear and Tear

                  Normal wear and tear and the need for regular maintenance
                  and overhaul will not constitute a defect or
                  nonconformance under this Subparagraph 12.9.

12.9.8            Exclusivity of Warranties and General Limitations of
                  Liability and Duplicate Remedies

                  The Lessee and the Lessor recognize and agree that the
                  Exclusivity of Warranties and General Limitations of
                  Liability provisions and the Duplicate Remedies
                  provisions contained in Clause 12 of the Agreement will
                  also apply to the foregoing warranties provided for in
                  this Subparagraph 12.9.

                  all deliveries for the Additional Aircraft are scheduled
                  by ***. However, in the event that the Manufacturer's
                  Commercial Constraints prevent the Seller from scheduling
                  delivery of an Additional Aircraft by ***, such deadline
                  will be extended to such later delivery date relating to
                  the applicable Additional Aircraft.

2.                DELIVERIES

                  Manufacturer's Commercial Constraints and Industrial
                  Constraints at the time of request.

                  Delivery positions offered by the Seller for Additional
                  Aircraft will be held for the Buyer during the five (5)
                  Working Day period following the Seller's offer. The
                  Buyer may exercise its option to reserve the delivery
                  position for each such Additional Aircraft

                  (i)      by written notice to the Seller and by making a
                           nonrefundable deposit payable to the Seller ***
                           due as set forth in Subclause 6.2.2.2 of the
                           Agreement, and

                  (ii)     provided that at no time will the number of
                           Reconfirmable Aircraft exceed the number of Firm
                           Aircraft then on order, plus the number of
                           Aircraft already delivered to the Buyer, ***.

Re:               CONVERSION RIGHTS

Ladies and Gentlemen:

                  US Airways Group, Inc. (the "Buyer"), and AVSA, S.A.R.L.
(the "Seller"), have entered into an Airbus A330/A340 Purchase Agreement
dated as of even date herewith (the "Agreement"), which covers, among other
things, the sale by the Seller and the purchase by the Buyer of certain
Aircraft, under the terms and conditions set forth in said Agreement. The
Buyer and the Seller have agreed to set forth in this Letter Agreement No.
4 (the "Letter Agreement") certain additional terms and conditions
regarding the sale of the Aircraft. Capitalized terms used herein and not
otherwise defined in this Letter Agreement will have the meanings assigned
thereto in the Agreement. The terms "herein," "hereof" and "hereunder" and
words of similar import refer to this Letter Agreement.

                  Both parties agree that this Letter Agreement will
constitute an integral, nonseverable part of said Agreement, that the
provisions of said Agreement are hereby incorporated herein by reference,
and that this Letter Agreement will be governed by the provisions of said
Agreement, except that if the Agreement and this Letter Agreement have
specific provisions which are inconsistent, the specific provisions
contained in this Letter Agreement will govern.


1.                CONVERSION RIGHT

1.1               In order to provide the Buyer with additional flexibility
                  to meet its future fleet mix requirements, the Seller
                  grants the Buyer aircraft type conversion rights under
                  the terms and conditions contained in this Paragraph 1
                  (the "Wide-Body Conversion Right").

                  (i)   The Conversion Right will grant the Buyer the right
                        to convert every Firm Aircraft and Reconfirmable
                        Aircraft into either A330-200 Aircraft, A330-300
                        Aircraft, A340-200 Aircraft or A340-300 Aircraft,
                        as applicable, beginning with the *** in the
                        schedule set forth in Clause 9 of the Agreement.

                  (ii)  The Conversion Right will be exercised by the Buyer
                        no later than

                           (a)  ***, and

                           (b)  *** to be converted into A340-200 Aircraft.

                  The Seller will endeavor to ***, subject to (i) the
                  Manufacturer's then existing Commercial Constraints and
                  Industrial Constraints and (ii) offers to other carriers.

                  Further, should the Seller or the Manufacturer or any of
                  their Affiliates engaged in the sale of aircraft of the
                  same type as the Aircraft ***.

                  (iii) The Conversion Right will be subject to the
                        Manufacturer's Commercial Constraints and
                        Industrial Constraints at the time the Buyer elects
                        to exercise its Conversion Right.

                   (iv) The Conversion Right will be exercised ***.

1.2               The Buyer's exercise of its Conversion Right with respect
                  to a particular Aircraft will result in an adjustment to
                  the Predelivery Payment Reference Price and Predelivery
                  Payments due in respect of the converted Aircraft (a
                  "Converted Aircraft").

                  If the Predelivery Payment Reference Price for a
                  Converted Aircraft is higher than it was for the Aircraft
                  from which it was converted (the "Original Aircraft"),
                  then the difference between the Predelivery Payments the
                  Buyer has paid and what it would have paid had the
                  Converted Aircraft been an Original Aircraft will be due
                  within three (3) Working Days of conversion, and
                  conversion will be effective when the Buyer pays such
                  difference.

                  ***

                                  FOR ***


l.                BASE PRICE

                  The Base Price of the *** is as quoted in Subparagraph
                  1.5 of Letter Agreement No. 5 to the Agreement.

2.                BASE PERIOD

                  ***

                  This Base Price is subject to adjustment for changes in
                  economic conditions as measured by data obtained from the
                  United States Department of Labor, Bureau of Labor
                  Statistics, and in accordance with the provisions of
                  Paragraphs 4 and 5 of this Appendix 1.

                  ECIb and ICb index values indicated in Paragraph 4 of
                  this Appendix 1 are based on publications available at
                  the date of signature of the Agreement and are United
                  States Department of Labor Bureau of Labor Statistics
                  computations corresponding to certain base years as
                  stipulated below in Paragraph 3. Should the Bureau of
                  Labor Statistics change such base year, it will be
                  necessary to restate such values in an appropriate
                  manner. Other changes (such as benchmark revision),
                  except those related to established errors from the
                  Bureau of Labor Statistics, will not be taken into
                  consideration.

3.                REFERENCE INDEXES

                  Material Index: "Industrial Commodities Index"
                  (hereinafter referred to as "ICI-Index"), published
                  monthly by the United States Department of Labor, Bureau
                  of Labor Statistics, in "Producer Prices and Price
                  Indexes" (Table 6: "Producer prices and price indexes for
                  commodity groupings and individual items"). (Base year
                  1982 = 100.)


4 -               REVISION FORMULA

                  ***

                  In determining the Revised Base Price at delivery of the
                  Aircraft, each quotient will be calculated to the nearest
                  ten thousandth (4 decimals). If the next succeeding place
                  is five (5) or more, the preceding decimal place will be
                  raised to the next higher figure. The final factor will
                  be rounded to the nearest ten thousandth (4 decimals).

                  After final computation, Pn will be rounded to the next
                  whole number (0.5 or more rounded to l).

5.                GENERAL PROVISIONS

5.1               Substitution of Indexes

                  In the event that:

                  (i)      the United States Department of Labor
                           substantially revises its methodology for
                           calculating any of the indexes referred to here
                           above, or

                  (ii)     the United States Department of Labor
                           discontinues, either temporarily or permanently,
                           any of the indexes referred to here above and
                           publication thereof, or

                  (iii)    the data samples used to calculate any of the
                           indexes referred to here above are substantially
                           changed,

                  The Seller and the Buyer will agree on a substitute
                  index.

                  Such substitute index will reflect as closely as possible
                  the actual variations in wage rates or in material
                  prices, as the case may be, used in the calculation of
                  the original index.

                  As a result of this selection of a substitute index, the
                  Seller and the Buyer will agree on appropriate
                  adjustments to be made to the price revision formula;
                  such adjustments may include, but will not be limited to,
                  allowing to combine the successive utilization of the
                  original index and of the substitute index, and other
                  methodologies designed to ensure consistency in the
                  numerators and denominators of the various quotients.

5.2               Final Index Values

                  The Revised Base Price at the date of Aircraft delivery
                  will be final and will not be subject to further
                  adjustments, of any kind, to the applicable indexes as
                  published at the date of Aircraft delivery.

           during performance demonstration as described in Subparagraph
           5.3 below may be such as to optimize the A330-200 Aircraft
           performance while meeting the minimum air conditioning
           requirements defined above. Unless otherwise stated no air will
           be bled from the engines for anti-icing.

4.5        The engines will be operated using not more than the engine
           manufacturer's maximum recommended outputs for take-off, maximum
           go-round, maximum continuous, maximum climb and cruise for
           normal operation unless otherwise stated.

4.6        Where applicable the Guarantees assume the use of an approved
           fuel having a density of 6.7 lb/US gallon and a lower heating
           value of 18,590 BTU/lb.

4.7        Speech interference level (SIL) is defined as the arithmetic
           average of the sound pressure levels in the 1,000, 2,000, and
           4,000 Hz octave bands A-weighted sound level (dBA) is as defined
           in the American National Standard Specification ANSI.4-1971.

4.8        The sound levels guaranteed in Subparagraph 3.2: i) will be

4        GUARANTEE CONDITIONS

4.1      The performance and noise certification requirements for the
         A340-300 Aircraft, except where otherwise noted, will be as stated
         in Section 02 of the Specification.

4.2      For the determination of FAR take-off and landing performance a
         hard level dry runway surface with no runway strength limitations,
         no obstacles, zero wind, atmosphere according to ISA, except as
         otherwise noted and the use of speedbrakes, flaps, landing gear
         and engines in the conditions liable to provide the best results
         will be assumed.

4.2.1    When establishing take-off and second segment performance no air
         will be bled from the engines for cabin air conditioning or
         anti-icing.

4.3      The en-route one engine inoperative climb performance will be
         established with the amount of engine air bleed associated with
         the maximum cabin altitude as specified in Section 21-30.32 of the
         Specification and an average ventilation rate not less than the
         amount defined in the Specification but no air will be bled from
         the engines for anti-icing.

4.4      Climb, cruise and descent performance associated with the

         anti-icing.

4.5      The engines will be operated using not more than the engine
         manufacturer's maximum recommended outputs for take-off, maximum
         go-round, maximum continuous, maximum climb and cruise for normal
         operation unless otherwise stated.

4.6      Where applicable the Guarantees assume the use of an approved fuel
         having a density of 6.7 lb/US gallon and a lower heating value of
         18,590 BTU/lb.

4.7      Speech interference level (SIL) is defined as the arithmetic
         average of the sound pressure levels in the 1,000, 2,000, and
         4,000 Hz octave bands A-weighted sound level (dBA) is as defined
         in the American National Standard Specification ANSI.4-1971.

4.8      The sound levels guaranteed in Subparagraph 3.2:

              i)    will be measured at the positions defined in Section

                    passenger seats will be the responsibility of the
                    Buyer.

4.9      For the purposes of the sound levels guaranteed in Subparagraph
         3.2.3 the APU and air conditioning system will be operating. Sound
         level measurements may be made at the prevailing ambient
         temperature with the air conditioning packs controlled to
         approximate air conditioning machinery rotational speed
         appropriate to an ambient temperature of 25(degree)C.


5        GUARANTEE COMPLIANCE

5.1      Compliance with the Guarantees will be demonstrated using
         operating procedures and limitations in accordance with those
         defined by the certifying Airworthiness Authority and by the

13 (the "Letter Agreement") certain additional terms and conditions
regarding the sale of the Aircraft. Capitalized terms used herein and not
otherwise defined in this Letter Agreement will have the meanings assigned

words of similar import refer to this Letter Agreement.

         Both parties agree that this Letter Agreement will constitute an

Agreement are hereby incorporated herein by reference, and that this Letter
Agreement will be governed by the provisions of said Agreement, except that
if the Agreement and this Letter Agreement have specific provisions which

Agreement will govern.

         The Seller, under its arrangement with the Manufacturer, has
negotiated and obtained the following Technical Dispatch Reliability
Guarantee from the Manufacturer with respect to the Aircraft, subject to
the terms, conditions, limitations and restrictions all as hereinafter set
out. The Seller hereby guarantees to the Buyer the performance by the

not otherwise defined therein will have the meanings assigned thereto in
the Agreement, except that the term "Seller" refers to the Manufacturer and
the term "Buyer" refers to the Seller.

         QUOTE

1.       SCOPE, COMMENCEMENT, DURATION

         This dispatch reliability guarantee (the "Guarantee") extends to
         the Aircraft fleet, will commence with delivery of the first
         Aircraft and will remain in force for a period of *** years (the
         "Term"), ***.
2.       DEFINITION

2.1      Revenue Flight

         A "Revenue Flight" is a flight as stipulated in the Buyer's time
         table, and any scheduled charter flight of the Aircraft.

2.2      Aircraft Inherent Malfunction

         An "Aircraft Inherent Malfunction" is a condition whereby
         maintenance action is necessary to reestablish serviceability of
         the Aircraft.

2.3      Dispatched

         An Aircraft will be deemed to have been "Dispatched" when it
         leaves the gate for a Revenue Flight.

2.4      Chargeable Delay

         A "Chargeable Delay" will be deemed to have occurred when, by more
         than fifteen (15) minutes and for reasons other than those defined
         under "Excluded Delay," a primary Aircraft Inherent Malfunction
         causes a Revenue Flight to depart later than the scheduled
         departure time.

2.5      Excluded Delay

         Any delay which is not a Chargeable Delay is an "Excluded Delay."
         Excluded Delays are specifically excluded from this Guarantee,
         even if consequently the Aircraft is subject to a delay. These
         Excluded Delays include delays in scheduled departure due to:

         "Achieved Dispatch Reliability" is the actual Dispatch Reliability
         obtained by the Aircraft fleet in regular revenue service and
         adjusted to the clauses of this Guarantee.

         Achieved Dispatch Reliability, expressed as a percent, will be
         computed every three months ("the Computation Period") and will be
         compared to the Guaranteed Dispatch Reliability level (as defined
         in Paragraph 3) at the end of each Computation Period.

         guarantee that an Aircraft available for dispatch will, on
         average, have a *** probability of being Dispatched without a
         Chargeable Delay. ***

4.       BUYER'S AND SELLER'S OBLIGATION

4.1      Buyer's and Seller's Obligations

         The Buyer's and Seller's specialists will mutually agree on the
         details of a Chargeable Delay reporting procedure not later than
         three (3) months before delivery of the first Aircraft.

4.2      Buyer's Obligations

         a)       The Buyer will regularly submit Chargeable Delay data on
                  a monthly basis not later than twenty (20) days after the
                  end of the reporting month. Such data must contain
                  detailed information on delays and Cancellations to allow
                  the Seller to assess the nature of system or component
                  malfunctions.

         b)       The Buyer will notify the Seller at any time that the
                  Achieved Dispatch Reliability is below the Guaranteed
                  Dispatch Reliability Level. After such notice, the Seller
                  will promptly take corrective actions. Upon request, all
                  reasonably necessary additional detailed operational and
                  engineering information will be provided by the Buyer in
                  order to allow the Seller to determine the necessary
                  action.

         c)       The Buyer will incorporate in and apply to the Aircraft
                  the procedures and modifications recommended by the
                  Seller to the extent necessary in order to improve the
                  Achieved Dispatch Reliability. Said modifications will be
                  incorporated and such procedures will be applied as soon
                  as is reasonably possible, consistent with the Buyer's
                  maintenance program, following receipt of instructions
                  and parts (if applicable) by the Buyer, provided that:

                  i)       the effect of such a procedure or modification is
                           substantiated to the Buyer's satisfaction,

                  ii)      application of such a procedure or modification is
                           economical and practical as determined by the
                           Buyer's customary analysis practice, and

                  iii)     ***

                  In the event of a disagreement between the Seller and the
                  Buyer as to the effectiveness of procedures or
                  modifications proposed by the Seller to increase the
                  achieved level, the Buyer will demonstrate to the Seller
                  that pursuant to its analysis, such a modification or
                  procedure is not effective.

                  Notwithstanding the Buyer's obligations above, the Buyer
                  may, at its option, decline to install such modification
                  or decline to follow such revised procedures as are
                  referred to above. If the Buyer so declines, the Seller
                  may adjust the Guaranteed Dispatch Reliability Level
                  downwards by an amount consistent with the improvement in
                  the Achieved Dispatch Reliability Level, based on
                  reasonable substantiation to the Buyer and on other
                  operators' experience, if any, that of the reliability
                  benefits of such modification or such revised procedures
                  are expected to cause.

         d)       Furthermore, the Buyer agrees to set its Aircraft fleet
                  technical dispatch reliability goals as shown in the
                  Buyer's regular reliability report (or equivalent) at a
                  level equal to or greater than the Guaranteed Dispatch
                  Reliability Level, so that both the Buyer's and Seller's
                  technical staff can aggressively pursue attainment of the
                  Guaranteed Dispatch Reliability Level.

4.3      Seller's Obligations

         During the Term, the Seller will provide technical and operational
         analyses of delays and cancellations and will develop corrections
         intended to reduce delays and, in the event that the Achieved
         Dispatch Reliability is below the Guaranteed Dispatch Reliability
         Level the Seller will, not later than six (6) months where
         practicable after notification by the Buyer and at no charge to
         the Buyer :

         a)       provide modified Manufacturer's items, either hardware of
                  software, to improve Achieved Dispatch Reliability,

         b)       make recommendations concerning the Aircraft operation and
                  maintenance programs, publications, and policies to improve
                  Achieved Dispatch Reliability,

         c)       assist the Buyer to cause Vendors action to improve the
                  Achieved Dispatch Reliability.

5.       ADJUSTMENT

         Any design, certification, regulatory, organizational structure or
         Aircraft operation changes outside the Seller's control that may
         have an effect upon the operation and dispatch characteristics of
         the Aircraft will be cause for reevaluation or adjustment of this
         Guaranteed Dispatch Reliability Level by mutual agreement between
         the Buyer and the Seller.

6.       ACHIEVED DISPATCH RELIABILITY REVIEW MEETINGS

         An Achieved Dispatch Reliability review meeting between the
         Seller's and the Buyer's representatives will be scheduled at the
         end of each six (6) month period of Aircraft operation, or at some
         other period to be mutually agreed. Representatives of the Buyer
         and the Seller will participate in the meeting and will:

         a)       review current Achieved Dispatch Reliability,

         b)       eliminate unsupported or non-Aircraft-inherent delay
                  claims from delay records to compute Achieved Dispatch
                  Reliability,

         c)       consider corrective action, if required,

         d)       review the Buyer's incorporation of modifications as stated
                  in Subparagraph 4.2 of this Letter Agreement and
                  requirements, if any, for reduction of  the Guaranteed
                  Dispatch Reliability Level,

         e)       review possible design, certification, regulatory,
                  organizational structure or Aircraft operation changes
                  and requirements, if any, necessitating adjustment of the
                  Guaranteed Dispatch Reliability Level.

7.       LIABILITY LIMITATION

         The Seller's liability for failure to meet the Dispatch
         Reliability Guarantee values will be governed solely by the terms
         of this Dispatch Reliability Guarantee.

         UNQUOTE

         In consideration of the assignment and subrogation by the Seller
         under this Letter Agreement in favor of the Buyer in respect of
         the Seller's rights against and obligations to the Manufacturer
         under the provisions quoted above, the Buyer hereby accepts such
         assignment and subrogation and agrees to be bound by all of the
         terms, conditions and limitations therein contained. The Buyer and
