                             PART 2: BOEING WARRANTY

1.       Applicability.
         -------------

         This warranty applies to all Boeing Products.  Warranties applicable to
Supplier  Products  are in Part 4.  Warranties  applicable  to  engines  will be
provided by Supplemental Exhibits to individual purchase agreements.

2.       Warranty.
         --------

     2.1 Coverage. Boeing warrants that at the time of delivery:

     (i) the  aircraft  will  conform  to the  Detail  Specification  except for
portions stated to be estimates, approximations or design objectives;

     (ii) all Boeing Products will be free from defects in material,  process of
manufacture  and  workmanship,  including  the  workmanship  utilized to install
Supplier Products, engines and BFE, and;

     (iii) all Boeing  Products  will be free from defects in design,  including
selection of materials and the process of  manufacture,  in view of the state of
the art at the time of design

     2.2 Exceptions.  The following  conditions do not constitute a defect under
this warranty:

     (i) conditions resulting from normal wear and tear;

     (ii) conditions resulting from acts or omissions of Customer; and

     (iii) conditions  resulting from failure to properly service and maintain a
Boeing Product .

     3. Warranty Periods.

         3.1  Warranty.  The warranty  period  begins on the date of aircraft or
Boeing Product delivery and ends: (i) after 48 months for Boeing aircraft models
777-200,  -300 or 737-600,  -700,  -800,  or new  aircraft  models  designed and
manufactured  with  similar,  new  technology;  or, (ii) after 36 months for any
other Boeing aircraft model.

         3.2  Warranty  on  Corrected  Boeing  Products.   The  warranty  period
applicable to a Corrected  Boeing Product,  including the workmanship to Correct
and install, resulting from a defect in material or workmanship is the remainder
of the initial warranty period for the defective Boeing Product it replaced. The
warranty period for a Corrected Boeing Product resulting from a defect in design
is 18 months or the  remainder  of the initial  warranty  period,  whichever  is
longer.  The 18 month  period  begins on the date of delivery  of the  Corrected
Boeing  Product or date of delivery of the kit or kits  furnished to Correct the
Boeing Product.

     3.3 Survival of  Warranties.  All warranty  periods are stated  above.  The
Performance Guarantees will  not survive delivery of the
aircraft.

4.       Remedies.
         --------

     4.1  Correction  Options.  Customer  may, at its option,  either  perform a
Correction  of a  defective Boeing  Product or return the
Boeing Product to Boeing for Correction.

     4.2 Warranty  Labor Rate. If Customer or its  Authorized  Agent  Corrects a
defective Boeing Product,  Boeing will reimburse Customer for Direct Labor Hours
at Customer's  established Warranty Labor Rate. Customer's  established Warranty
Labor Rate will be the greater of the standard  labor rate or 150% of Customer's
Average  Direct Hourly Labor Rate. The standard labor rate paid by Boeing to its
customers is established and published  annually.  Prior to or concurrently with
submittal of Customer's first claim for Direct Labor reimbursement, Customer may
notify Boeing of Customer's  then-current  Average Direct Hourly Labor Rate, and
thereafter  notify  Boeing of any  material  change in such  rate.  Boeing  will
require information from Customer to substantiate such rates.

         4.3  Warranty  Inspections.  In  addition  to the  remedies  to Correct
defects in Boeing  Products,  Boeing  will  reimburse  Customer  for the cost of
Direct Labor to perform  certain  inspections  of the aircraft to determine  the
occurrence of a condition Boeing has identified as a covered defect, provided:

     4.3.1 the  inspections  are  recommended  by a service  bulletin or service
letter issued by Boeing during the warranty period; and

     4.3.2 such reimbursement will not apply to any inspections  performed after
a Correction is available to Customer.

     4.4 Credit Memorandum Reimbursement. Boeing will make all reimbursements by
credit  memoranda which  may be applied toward
the purchase of Boeing goods and services.

     4.5  Maximum   Reimbursement.   Unless  previously   agreed,   the  maximum
reimbursement  for Direct Labor and Direct Materials used to Correct a defective
Boeing  Product will not exceed 65% of Boeing's  then-current  sales price for a
new replacement Boeing Product.

5.       Discovery and Notice.
         --------------------

         5.1      For a claim to be valid:

     (i) the defect must be discovered during the warranty period; and

     (ii) Boeing  Warranty must receive written notice of the discovery no later
than 90 days after  expiration of the warranty  period.  The notice must include
sufficient information to substantiate the claim.

     5.2 Receipt of Customer's or its Authorized Agent's notice of the discovery
of a defect  secures  Customer's  rights to remedies  under this Exhibit C, even
though a Correction is performed after the expiration of the warranty period.

     5.3 Once  Customer has given valid notice of the  discovery of a defect,  a
claim  should be  submitted  as soon as  practicable  after  performance  of the
Correction.

     5.4 Boeing may  release  service  bulletins  or  service  letters  advising
Customer of the availability of certain warranty  remedies.  When such advice is
provided,  Customer  will be  deemed  to have  fulfilled  the  requirements  for
discovery  of the defect and  submittal of notice under this Exhibit C as of the
date specified in the service bulletin or service letter.

6.       Filing a Claim.
         --------------

     6.1  Authority to File.  Claims may be filed by Customer or its  Authorized
Agent.  Appointment of an Authorized  Agent will only be effective upon Boeing's
receipt  of  the  Authorized  Agent's  express  written  agreement,  in  a  form
satisfactory to Boeing,  to be bound by and to comply with all applicable  terms
and conditions of this Aircraft General Terms Agreement.

         6.2      Claim Information.
                  -----------------

     6.2.1  Claimant is  responsible  for providing  sufficient  information  to
substantiate  Customer's  rights to  remedies  under this  Exhibit C. Boeing may
reject  a  claim  for  lack  of  sufficient  information.  At  a  minimum,  such
information must include:

     (i) identity of claimant;

     (ii) serial or block number of the aircraft on which the  defective  Boeing
Product was delivered;

     (iii) part number and nomenclature of the defective Boeing Product;

     (iv) purchase order number and date of delivery of the defective spare part

     (v) description and substantiation of the defect;

     (vi) date the defect was discovered;

     (vii) date the Correction was completed;

     (viii) the total flight hours or cycles accrued;

     (ix) an itemized  account of direct labor hours  expended in performing the
Correction;  and (x) an itemized account of any direct materials incorporated in
the Correction.

     6.2.2  Additional  information  may be required  based on the nature of the
defect and the remedies requested.

         6.3      Boeing Claim Processing.
                  -----------------------

                  6.3.1 Any claim for a Boeing  Product  returned by Customer or
its Authorized Agent to Boeing for Correction must accompany the Boeing Product.
Any claim not associated  with the return of a Boeing Product must be signed and
submitted  in writing  directly by Customer  or its  Authorized  Agent to Boeing
Warranty.

                  6.3.2  Boeing  will  promptly  review  the claim and will give
notification  of claim approval or rejection.  If the claim is rejected,  Boeing
will provide a written explanation.

7.       Corrections Performed by Customer or Its Authorized Agent.
         ---------------------------------------------------------

         7.1 Facilities Requirements. Provided Customer, its Authorized Agent or
its third party  contractor,  as  appropriate,  are certified by the appropriate
Civil  Aviation  Authority  or  Federal  Aviation  Authority,  Customer  or  its
Authorized  Agent may, at its option,  Correct  defective Boeing Products at its
facilities, or may subcontract Corrections to a third party contractor.

         7.2  Technical  Requirements.  All  Corrections  done by Customer,  its
Authorized  Agent or a third party  contractor  must be performed in  accordance
with  Boeing's   applicable   service   manuals,   bulletins  or  other  written
instructions, using parts and materials furnished or approved by Boeing.

         7.3      Reimbursement.
                  -------------

                  7.3.1 Boeing will  reimburse  Customer's  reasonable  costs of
Direct  Materials  and Direct Labor  (excluding  time  expended for overhaul) at
Customer's Warranty Labor Rate to Correct a defective Boeing Product. Claims for
reimbursement must contain sufficient  information to substantiate  Direct Labor
hours expended and Direct Materials  consumed.  Customer or its Authorized Agent
may be required to produce invoices for materials.

                  7.3.2   Reimbursement   for  Direct  Labor  hours  to  perform
Corrections stated in a service bulletin will be based on the labor estimates in
the service bulletin.

                  7.3.3  Boeing  will  reimburse   Customer's   freight  charges
associated  with a Correction of a defect on a Boeing  Product  performed by its
Authorized Agent or a third party contractor.

     7.4  Disposition of Defective  Boeing Products  Beyond  Economical  Repair.

                  7.4.1 A defective Boeing Product found to be beyond economical
repair (see Para. 4.5 Maximum Reimbursement) will be retained for a period of 60
days from the date Boeing receives  Customer's claim.  During the 60 day period,
Boeing  may  request   return  of  such  Boeing   Products  for  inspection  and
confirmation of a defect.

                  7.4.2 After the 60 day period, a defective Boeing Product with
a value of U.S. $2000 or less may be scrapped without notification to Boeing. If
such Boeing  Product has a value greater than U.S.  $2000,  Customer must obtain
confirmation  of   unrepairability   by  Boeing's  on-site   Customer   Services
Representative  prior  to  scrapping.  Confirmation  may be in the  form  of the
Representative's  signature on Customer's claim or through direct  communication
between the Representative and Boeing Warranty.

8.       Corrections Performed by Boeing.
         -------------------------------

         8.1 Freight Charges. Customer or its Authorized Agent will pay shipping
charges to return a Boeing Product to Boeing.  Boeing will reimburse Customer or
its  Authorized  Agent for the charge for any item  determined  to be  defective
under this Aircraft General Terms Agreement. Boeing will pay shipping charges to
return the Corrected Boeing Product.

         8.2 Customer Instructions.  The documentation shipped with the returned
defective  Boeing  Product  may  include  specific  technical  instructions  for
additional  work to be  performed  on the Boeing  Product.  The  absence of such
instructions  will evidence  Customer's  authorization for Boeing to perform all
necessary  Corrections  and work  required  to return  the  Boeing  Product to a
serviceable condition.

         8.3      Correction Time Objectives.
                  --------------------------

                  8.3.1 Boeing's  objective for making Corrections is 10 working
days  for  avionics  and  electronic  Boeing  Products,   30  working  days  for
Corrections of other Boeing Products  performed at Boeing's  facilities,  and 40
working  days for  Corrections  of other Boeing  Products  performed at a Boeing
subcontractor's  facilities.  The  objectives  are measured from the date Boeing
receives the defective Boeing Product and a valid claim to the date Boeing ships
the Correction.

                  8.3.2 If Customer has a critical parts shortage because Boeing
has exceeded a Correction  time objective and Customer has procured spare Boeing
Products  for the  defective  Boeing  Product in  quantities  shown in  Boeing's
Recommended  Spare  Parts  List  (RSPL)  or  Spares  Planning  and  Requirements
Evaluation Model  (M-SPARE),  then Boeing will either expedite the Correction or
provide an  interchangeable  Boeing  Product on a no charge  loan or lease basis
until the Corrected Boeing Product is returned.

         8.4      Title Transfer and Risk of Loss.
                  -------------------------------

     8.4.1  Title to and risk of loss of any Boeing  Product  returned to Boeing
will at all times remain with  Customer or any other title holder of such Boeing
Product. While Boeing has possession of the returned Boeing Product, Boeing will
have only such  liabilities  as a bailee for mutual benefit would have, but will
not be liable for loss of use.

     8.4.2 If a Correction  requires  shipment of a new Boeing Product,  then at
the time Boeing ships the new Boeing Product,  title to and risk of loss for the
returned  Boeing Product will pass to Boeing,  and title to and risk of loss for
the new Boeing Product will pass to Customer.

9.       Returning an Aircraft.
         ---------------------

     9.1  Conditions.  An aircraft  may be returned to Boeing's  facilities  for
Correction only if:

     (i) Boeing and Customer agree a covered defect exists;

     (ii) Customer lacks access to adequate  facilities,  equipment or qualified
personnel to perform the Correction; and

     (iii) it is not  practical,  in Boeing's  estimation,  to  dispatch  Boeing
personnel to perform the Correction at a remote site.

     9.2  Correction  Costs.  Boeing will perform the Correction at no charge to
Customer.  Subject to the  conditions  of Article  9.1,  Boeing  will  reimburse
Customer for the costs of fuel,  oil and landing  fees  incurred in ferrying the
aircraft to Boeing and back to Customer's facilities. Customer will minimize the
length of both flights.

     9.3  Separate  Agreement.  Boeing and  Customer  will enter into a separate
agreement  covering  return of the aircraft and  performance of the  Correction.
Authorization by Customer for Boeing to perform additional work that is not part
of the Correction must be received within 24 hours of Boeing's request.  If such
authorization  is not received  within 24 hours,  Customer  will be invoiced for
work performed by Boeing that is not part of the Correction.

10.      Insurance.
         ---------

         The provisions of Article 8.2 "Insurance",  of this AGTA, will apply to
any work performed by Boeing in accordance  with Customer's  specific  technical
instructions,  to the  extent  any legal  liability  of Boeing is based upon the
content of such instructions.

11.      Disclaimer and Release; Exclusion of Liabilities.
         ------------------------------------------------

         11.1   DISCLAIMER  AND  RELEASE.   THE   WARRANTIES,   OBLIGATIONS  AND

     (D) ANY OBLIGATION, LIABILITY, RIGHT, CLAIM OR REMEDY FOR LOSS OF OR DAMAGE
TO ANY AIRCRAFT.

         11.2 EXCLUSION OF CONSEQUENTIAL AND OTHER DAMAGES.  BOEING WILL HAVE NO
OBLIGATION OR LIABILITY, WHETHER ARISING IN CONTRACT (INCLUDING WARRANTY), TORT,
WHETHER OR NOT ARISING FROM THE NEGLIGENCE OF BOEING, OR OTHERWISE,  FOR LOSS OF
USE, REVENUE OR PROFIT,  OR FOR ANY OTHER  INCIDENTAL OR  CONSEQUENTIAL  DAMAGES
WITH  RESPECT  TO ANY  NONCONFORMANCE  OR  DEFECT  IN ANY  AIRCRAFT,  MATERIALS,
TRAINING,  SERVICES OR OTHER THING  PROVIDED  UNDER THIS AGTA AND THE APPLICABLE
PURCHASE AGREEMENT.

         11.3 Definitions. For the purpose of this Article, "BOEING" or "Boeing"
is defined as The Boeing Company, its divisions,  subsidiaries,  affiliates, the
assignees of each,  and their  respective  directors,  officers,  employees  and

         where:

                  P =      price to Customer for the replacement part
                  C =      SLP Component sales price at time of Correction
                  T        = total age in months of the  defective or failed SLP
                           Component  from the date of  delivery  to Customer to

1.       Supplier Warranties and Supplier Patent and Copyright Indemnities.
         -----------------------------------------------------------------

         Boeing will use diligent  efforts to obtain  warranties and indemnities
against patent and copyright infringement enforceable by Customer from Suppliers
of Supplier  Products (except for BFE and engines)  installed on the aircraft at
the time of  delivery  that were  selected  and  purchased  by  Boeing,  but not
manufactured  to Boeing's  detailed  design.  Boeing will furnish  copies of the
warranties  and  patent and  copyright  indemnities  to  Customer  contained  in

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

         3.1  If  the  Supplier  defaults  in  the  performance  of  a  material
obligation under its warranty,  and Customer  provides evidence to Boeing that a

                       PART 5: BOEING INTERFACE COMMITMENT


1.       Interface Problems.
         ------------------

         An Interface Problem is defined as a technical problem in the operation
of an aircraft or its systems experienced by Customer, the cause of which is not
readily  identifiable by Customer but which Customer believes to be attributable
to either the  design  characteristics  of the  aircraft  or its  systems or the
workmanship used in the installation of Supplier Products. In the event Customer
experiences an Interface  Problem,  Boeing will,  without  additional  charge to
Customer,  promptly conduct an investigation and analysis to determine the cause
or causes of the Interface Problem.  Boeing will promptly advise Customer at the
conclusion  of its  investigation  of  Boeing's  opinion as to the causes of the
