                                     PART A

                                 BOEING WARRANTY


1.           Warranties.

             Subject to the exceptions set forth herein,  Boeing  warrants that,
at the  time of  delivery,  each  Aircraft,  including  all  installed  systems,
accessories, equipment and parts, will:

             1.1  conform  to the  Detail  Specification,  as it may be  changed
pursuant  to this  Agreement,  except  such  portions  stated  to be  estimates,
approximations,  design  objectives,  or design  criteria,  or  described as not
guaranteed;

             1.2  be free from  defects in material and  workmanship,  including
process of manufacture; and

             1.3 be free from  defects in design,  including  selection  of (i)
materials  and (ii) process of  manufacture,  in view of the state of the art at
the time of design.

             For  purposes  of this  Boeing  Warranty,  nonconformance  with the
Detail  Specification,  defects in material or workmanship and defects in design
may  hereinafter  be called  "defects"  or a  "defect",  and the term  "system",
"accessory", "equipment" or "part" may hereinafter be called "item" or "items."

2.           Exceptions.

             The  warranties  above will not apply to BFE.  The  warranty  above
covering  material and  workmanship  and the warranty above covering design will
not  apply  to  Engines  or to any  other  item  purchased  by  Boeing  but  not
manufactured  to Boeing's  detailed  design.  However,  any defect in the Boeing
workmanship  installing  such BFE,  Engines or other items in an  Aircraft  will
constitute a defect in workmanship.

3.           Survival of Warranties.

             Neither the  warranty of  conformance  to the Detail  Specification
applicable to Engines and other items  purchased by Boeing but not  manufactured
to Boeing's detailed design, nor any Performance Guarantees, will

survive delivery of the Aircraft. The remaining warranties set forth herein will
survive delivery of the Aircraft,  subject to the limitations and conditions set
forth herein.

4.           Warranty Periods and Claims.

             4.1         The warranty periods are:

                         4.1.1       As to a defect in conformance to the
Detail Specification, [XX] months after delivery of each Aircraft, and

                         4.1.2       As to a defect in material, workmanship
or design in any item, [XX] months after delivery of each Aircraft in which such
item was initially installed.

             4.2  Boeing's  Product   Assurance   Regional  Manager  at  Renton,
Washington   must  receive  the  warranty  claim  in  writing  at  the  earliest
practicable time after the defect becomes apparent but in no event later than 90
days after expiration of the applicable warranty period.

             4.3 Such warranty  claim must include the data set forth below and,
if reasonably  requested by Boeing,  reasonable evidence that the claimed defect
did not result from any act or omission of Buyer.

                         4.3.1       Identity of the item or Aircraft  involved,
including Boeing part number, serial number if applicable,  nomenclature and the
quantity claimed to be defective;

                         4.3.2       Identity  of  the  Aircraft  on  which  the
claimed item was installed as original equipment;

                         4.3.3       Date the  claimed  defect  became  apparent
which will be the date such defect was  discovered by Buyer or the warranty date
set forth in a Boeing service bulletin or service letter,  whichever date occurs
first; and

                         4.3.4       Description   of  the  claimed  defect  and
circumstances, including Boeing service bulletin or Boeing service letter number
if claim involves a service bulletin or letter.

             4.4 Upon  completion  of  Boeing's  warranty  claim  investigation,
including  examination of any item or Aircraft  returned to Boeing,  Boeing will
provide a written  disposition of its warranty  claim findings to Buyer.  In the
event Boeing must reject Buyer's warranty claim, Boeing will

provide reasonable substantiation of such rejection in its disposition.

5.           Remedies.

             Buyer's remedies under this Boeing Warranty are as follows:

             5.1 As to a defect in conformance to the Detail Specification,  the
correction at Boeing's expense of such defect;  provided,  however,  that Boeing
will not be obligated to correct any defect that has no material  adverse effect
on the  maintenance,  use or operation of the Aircraft.  The warranty period for
the corrected item will be the unexpired warranty period for the defective item.

             5.2 As to a defect in  material or  workmanship,  (i) the repair at
Boeing's expense of such defect or, (ii) at Boeing's option,  the replacement of
such item with a similar  item  free  from  defect or the  issuance  of a credit
memorandum to reimburse Buyer for a spare part previously  purchased from Boeing
as the  replacement  for such  defective  item.  The warranty  period for either
correction will be the unexpired warranty period for the defective item.

             5.3 As to a defect in design, the correction at Boeing's expense of
such defect.  The warranty  period for such correction is 18 months from receipt
by Buyer of  corrective  material  or the end of the  original  design  warranty
period for the defective item, whichever is later.

             5.4 Boeing will issue a credit memorandum to reimburse Buyer at the
Warranty  Labor Rate for the direct  labor hours  required  for removal from the
Aircraft  of a  defective  item and the  reinstallation  in the  Aircraft of the
corrected item.

6.           Returned Items.

             Unless otherwise  provided in this Agreement,  the Aircraft or item
claimed to be defective must be returned to Boeing as soon as practicable. Buyer
may also provide specific technical repair or correction  instructions with such
return. The absence of such instructions will evidence Buyer's authorization for
Boeing to proceed using Boeing information and data. The following criteria will
apply with respect to return of Aircraft or items to Boeing:

             6.1         As to Aircraft:


P.A. No. 1947                          B
K/WPA                                 A-3



<PAGE>





                         6.1.1       An Aircraft may be returned only if

                                     6.1.1.1  substantially  all the  work to be
performed by Boeing is covered by this Boeing Warranty, and

                                     6.1.1.2  Buyer does not have the capability
to perform,  nor is it practical for Boeing  personnel to perform,  the warranty
work away from Boeing's facilities.

                         6.1.2       All  warranty  work  will be  performed  at
Boeing's expense,  with reasonable  efforts to minimize Aircraft  out-of-service
time. In addition,  Boeing will reimburse  Buyer by issuing a credit  memorandum
for the cost of fuel,  oil and landing fees incurred in ferrying the Aircraft to
Boeing's  facilities  and in ferrying the Aircraft  back to Buyer's  facilities.
Buyer will minimize the length of both ferry flights.

                         6.1.3       Any  nonwarranty  work  performed by Boeing
will be paid for by Buyer at Boeing's then-standard rates.

                         6.1.4       A  separate  agreement  based  on  Boeing's
then-standard  form will be entered into to cover the return of and work on such
Aircraft.

             6.2         As to any system, accessory, equipment or part:

                         6.2.1       All  warranty  work  will be  performed  at
Boeing's expense,  with reasonable efforts to minimize  out-of-service  time for
items returned.

                         6.2.2       Boeing's  turnaround-time   objectives  for
repair or replacement  are: 10 working days for avionic and electronic items and
30 working  days for other items when  corrected at Boeing's  facilities,  or 40
working  days  when  corrected  at the  facilities  of a  Boeing  subcontractor.
Turnaround time starts the date Boeing receives the returned item, together with
Buyer's  warranty  claim  describing  the work, and ends the date of shipment by
Boeing of such  item.  If a  turnaround-time  objective  is not  achieved  and a
resultant  critical  parts  shortage  is  experienced  by  Buyer,  and Buyer has
procured  spare parts for such item in  accordance  with the Boeing  Recommended
Spare Parts List, Boeing will, upon request from Buyer, either:

<PAGE>





                                     6.2.2.1  expedite repair or replacement  of
the item or

                                     6.2.2.2  provide  a  similar  item   on   a
no-charge  loan or no-charge  lease basis until the repaired or replaced item is
provided to Buyer.

                         6.2.3       The freight  charge for  shipment to Boeing
Boeing of any item will be paid by Buyer;  however,  Boeing will reimburse Buyer
by issuing a credit  memorandum  for such charge for any item  determined  to be
defective under this Boeing Warranty. The freight charge for the return shipment
to Buyer of any such  defective  item  which  has  been  repaired,  replaced  or
corrected pursuant to this Boeing Warranty will be paid by Boeing.

             6.3 Title to and risk of loss of any  Aircraft or item  returned to
Boeing  will at all times  remain  with  Buyer  and/or  any other  owner of such
Aircraft or item,  except that at the time Boeing  ships a  replacement  item to
Buyer,  title to and risk of loss (i) for the returned  item will pass to Boeing
and (ii) for the  replacement  item will pass to Buyer.  While  Boeing has care,
custody  and  control  of an  Aircraft  or item,  Boeing  will  have  only  such
liabilities  as a bailee for mutual  benefit would have,  but will not be liable
for loss of use.

7.           Nonrepairable Items.

             Buyer  may  scrap  any  defective   nonrepairable   item  having  a
then-current  Boeing spare part selling price of [XXXX] or less and make a claim
for a replacement item. For a defective nonrepairable item having a then-current
Boeing  spare part selling  price  greater than  [XXXX],  an  authorized  Boeing
representative must confirm the nonrepairability of any such item. Buyer's claim
for an item with a spare part selling price  exceeding  [XXXX] must include such
confirmation.

8.           Reimbursement for Certain Inspection Labor Costs.

             8.1 In addition to the remedies set forth in this Boeing  Warranty,
Boeing will reimburse Buyer by issuing a credit memorandum at the Warranty Labor
Rate for the direct labor hours  expended by Buyer in performing  inspections of
the Aircraft to determine  whether or not a covered defect exists in any system,
accessory,  equipment or part manufactured to Boeing's detailed design, provided
that:

K/WPA                                 A-5



<PAGE>


                         8.1.1       such   inspections  are  recommended  by  a
Boeing  service  bulletin or service  letter  issued by Boeing  within 36 months
after delivery of such Aircraft, and

                         8.1.2       such  reimbursement  will not  apply to any
inspections performed as an alternative to accomplishing  corrective action when
such  corrective  action is available to Buyer at the time such  inspections are
performed.

             8.2 If a covered  defect is  determined to exist as a result of the
foregoing  inspections,  the remedies  under this Boeing  warranty will apply to
Aircraft  or  items  in  warranty  as of the  warranty  date  set  forth  in the
applicable  Boeing service bulletin or service letter or the date the defect was
discovered by Buyer, whichever date occurs first.

9.           Wear and Tear.

             Normal  wear and tear and the  need  for  regular  maintenance  and
overhaul will not constitute a defect.

10.          Disclaimer and Release; Exclusion of Liabilities.

             This Part A and the rights and remedies of Buyer and obligations of
Boeing  herein are  subject to the  Disclaimer  and  Release  and  Exclusion  of
Consequential and Other Damages provisions of Article 12 of this Agreement.

11.          Buyer's Indemnification of Boeing.

             The  provisions of Part E, "Buyer's  Indemnification  of Boeing and
Insurance"  of Exhibit C, will apply to all  warranty  work  performed by Boeing
hereunder in accordance  with Buyer's  specific  technical  repair or correction
instructions,  to the  extent  any legal  liability  of Boeing is based upon the
content of such instructions.

5.           Reimbursement.

             Upon  approval  of Buyer's  claim for  reimbursement,  Boeing  will
reimburse Buyer by issuing a credit memorandum as follows:

             5.1         Direct Labor.

                         At the Warranty Labor Rate  specified  herein for labor
hours  expended  by Buyer's  direct  labor  employees  in  performing  the work,
including removal,  disassembly,  inspection,  bench testing,  reassembly, final
inspection, and reinstallation,  but not to exceed Boeing's estimate of required
labor hours, and excluding time for overhaul.

             5.2         Direct Materials.

                         At the invoice  cost to Buyer for all direct  materials
incorporated  in the work,  excluding  (i)  materials  used for  overhaul,  (ii)
materials  furnished  by Boeing  at no  charge,  (iii)  materials  which  exceed
Boeing's  estimate of required  materials,  and (iv)  allowances  for  handling,
overhead, taxes, customs duties and the like.

             5.3         Warranty Labor Rate.

                         The  Warranty  Labor Rate is [XXXX] per hour or [X]% of
Buyer's  average  direct  hourly  labor rate,  whichever  is  greater.  For this
purpose,  "average  direct  hourly labor rate" is defined as the average  hourly
rate (excluding all fringe benefits,  premium-time  allowances,  social charges,
business taxes and the like) paid by Buyer to Buyer's  employees  whose jobs are
directly related to the performance of the work.  Prior to or concurrently  with
submittal  of Buyer's  first  claim for labor  reimbursement,  Buyer will notify
Boeing of Buyer's  then-current average direct hourly labor rate, and thereafter
notify Boeing of any material change in such rate.  Boeing may require data from
Buyer to substantiate such rates.

             5.4         Limitation.

                         The total  reimbursement  with  respect  to the  direct
labor and  direct  materials  incorporated  in the work,  will not exceed 65% of
Boeing's  then-current  sales price for the item unless a greater  percentage is
established for a particular item by written agreement between Boeing and Buyer.

All claims for  reimbursement  will be subject to audit by Boeing.  Boeing  will
promptly notify Buyer of Boeing's disposition of each claim submitted hereunder.

6.           Replaced Parts.

replaced  parts will be tagged with the assembly part number,  the serial number
and the warranty claim number and retained for a period of 60 days following the

1.           Supplier Warranties and Supplier Patent Indemnities.

             Boeing will use diligent efforts to obtain adequate  warranties and
indemnities against patent infringement  enforceable by Buyer from manufacturers
(Suppliers)  of  systems,  accessories,  equipment  or  parts  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 such
warranties  and  patent  indemnities  to Buyer  prior to  delivery  of the first
Aircraft.

2.           Boeing Assistance in Administration of Supplier Warranties.

             Buyer will be responsible  for submitting  warranty claims directly
to Suppliers;  however,  if Buyer  experiences  problems  enforcing any Supplier
warranty  obtained by Boeing for Buyer,  Boeing will conduct an investigation of
such problems and assist Buyer in the resolution of such claims.

3.           Boeing Support in Event of Supplier Default.

             3.1 If any  Supplier  defaults  in the  performance  of a  material
obligation under a design,  material or workmanship  warranty obtained by Boeing
for Buyer, and Buyer provides evidence to Boeing that such default has occurred,
then the  equivalent  warranty and related  provisions set forth in this Product
Assurance Document will apply to the claimed defect.

             3.2 At Boeing's  request,  Buyer will assign to Boeing,  and Boeing
will be subrogated to, Buyer's  rights against the  manufacturer  providing such
Supplier warranty.

part is enjoined, CFM shall expeditiously, at its own expense and at its option,
either (1) procure for Buyer the rights to continue  using said product or part;
(2) replace the same with  satisfactory and  noninfringing  product or part; (3)

1.           Interface Problems.

             If Buyer  experiences  technical  problems in the  operation  of an
Aircraft or its systems, the cause of which is not readily identifiable by Buyer
but which Buyer believes to be attributable to the design characteristics of the
Aircraft or its systems  (Interface  Problem),  Boeing will,  without additional
charge to Buyer, promptly conduct an investigation and analysis to determine the
cause or causes of the Interface Problem and to recommend such corrective action
as may be  feasible.  Buyer will furnish to Boeing all data and  information  in
Buyer's possession  relevant to the Interface  Problem,  and will cooperate with
Boeing in the conduct of investigations  and tests.  Boeing will promptly advise
Buyer at the  conclusion  of its  investigation  of  Boeing's  opinion as to the
causes of the  Interface  Problem and Boeing's  recommendation  as to corrective
action.

Boeing will  correct the design of such item to the extent of any  then-existing
obligations of Boeing under the provisions of the applicable  Boeing Warranty or
Boeing Service Life Policy.

3.           Manufacturer Responsibility.

attributable  to the design of an item not  manufactured  to  Boeing's  detailed
design,  Boeing will assist  Buyer in  processing a warranty  claim  against the
manufacturer of such item.

4.           Joint Responsibility.

             If  Boeing  determines  that the  Interface  Problem  is  partially
attributable to the design of an item  manufactured to Boeing's  detailed design
and  partially to the design of an item not  manufactured  to Boeing's  detailed
design, Boeing will seek a solution to the Interface Problem through the
