3.4      Supplier/Equipment Selection for SPE.

         3.4.1 In addition to those responsibilities described above, for
galleys and seats the following provisions apply with respect to Customer's
selection of suppliers:

         Galley Requirements. Customer will provide Boeing the definitive

         3.4.2 Boeing shall retain the right to approve Customer's selected
supplier's and/or part numbers, for each item of SPE.

3.5      Changes to SPE.

         After the Purchase Agreement is signed, changes to SPE may only be made
by and between Boeing and the suppliers. Customer's contacts with SPE suppliers
relating to design (including selection of materials and colors), weights,
prices or schedules are for informational purposes only. If Customer wants any
changes made, requests must be made directly to Boeing for coordination with the
supplier.

3.6      Proprietary Rights for SPE.

         Boeing's obligation to purchase SPE will not impose upon Boeing any
obligation to compensate Customer or any supplier for any proprietary rights
Customer may have in the design of the SPE.

3.7      Remedies for SPE.

         If Customer does not comply with the obligations above, Boeing may:

         (ii)     deliver the Aircraft without installing the SPE;

         (iii)    substitute a comparable part and invoice Customer for the
                  cost;

4.3      Software for CSE.

         CSE systems may contain software of the following two types.

         4.3.1 Systems Software. The software required to operate and certify
the CSE systems on the Aircraft is the Systems Software and is part of the CSE.

         4.3.2 Customer's Software. The software accessible to the Aircraft
passengers which controls Customer's specified optional features is Customer's
Software and is not part of the CSE.

                  4.3.2.1 Customer is solely responsible for specifying
Customer's Software functional and performance requirements and ensuring that
Customer's Software meets such requirements. Customer and Customer's Software
supplier will have total responsibility for the writing, certification,
modification, revision, or correction of any of Customer's Software. Boeing
will not perform the functions and obligations described in paragraph 11.2
above, nor the Project Manager's functions described in Attachment D, for
Customer's Software.

                  4.3.2.2 The omission of any Customer's Software or the lack
of any functionality of Customer's Software will not be a valid condition for
Customer's rejection of the Aircraft at the time of Aircraft delivery.

                  4.3.2.3 Boeing has no obligation to approve any documentation
to support Customer's Software certification. Boeing will only review and
operate Customer's Software if in Boeing's reasonable opinion such review and
operation is necessary to certify the CSE system on the Aircraft.

                  4.3.2.4 Boeing will not be responsible for obtaining FAA
certification for Customer's Software.

4.4.     Changes to CSE.

         4.4.1 After Boeing and Supplier have entered into a contract for the
purchase of the CSE, changes to such contract may only be made by Boeing. Any
Customer request for changes to the CSE specification after the Boeing/Supplier
contract has been signed must be made in writing directly to Boeing. Boeing
shall respond to such request by Customer in a timely manner. If such change is
technically feasible and Boeing has the resources and time to incorporate such
change, then Boeing shall negotiate with the Supplier to incorporate such
change into the contract for the CSE. Any Supplier price increase resulting
from such a change will be negotiated between Customer and Supplier. 

                                    Page 7

P.A. No. 2022

         4.4.2 Boeing and Customer recognize that the developmental nature of
the CSE may require changes to the CSE or the Aircraft in order to ensure (i)
compatibility of the CSE with the Aircraft and all other Aircraft systems, and
(ii) FAA certification of the Aircraft with the CSE installed therein. In such
event Boeing will notify Customer and recommend to Customer the most practical
means for incorporating any such change. If within 15 days after such
notification Customer and Boeing through negotiations cannot mutually agree on
the incorporation of any such change or alternate course of action, then the
remedies available to Boeing in Article 15 shall apply.

         4.4.3 The incorporation into the Aircraft of any mutually agreed
change to the CSE may result in Boeing adjusting the price of the Change
Request contained in Attachment C to this Letter Agreement.

         4.4.4 Boeing's obligation to obtain FAA certification of the Aircraft
with the CSE installed is limited to the CSE as described in Attachment C, as
Attachment C may be amended from time to time.

         4.4.5 Boeing shall notify Customer in a timely manner in the event of
a default by a Supplier under the Supplier's contract with Boeing. Within 15
days of Customer's receipt of such notification, Boeing and Customer shall
agree through negotiations on an alternative Supplier or other course of
action. If Boeing and Customer are unable to agree on an alternative Supplier
or course of action within such time, the remedies available to Boeing in
Article 15 shall apply. In the event of a BFE/SPE Seat Supplier default, Boeing
and Customer mutually agree to the contingency plan as described in Exhibit C
to the AGTA.

4.5      Exhibits B and C to the AGTA for CSE.

         CSE is deemed to be BFE for the purposes of Exhibit B, Customer
Support Document, and Exhibit C, the Product Assurance Document, of the AGTA.

4.6      Boeing's Remedies for CSE.

         If Customer does not comply with any of its obligations set forth
herein, Boeing may:

         4.6.1 delay delivery of the Aircraft pursuant to the provisions of
Article 7, Excusable Delay, of the AGTA; or

         4.6.2 deliver the Aircraft without part or all of the CSE installed,
or with part or all of the CSE inoperative; or

                                    Page 8

P.A. No. 2022 
   44

         4.6.3 increase the Aircraft Price by the amount of Boeing's additional
costs attributable to such noncompliance.

4.7      Price Effect of CSE on Aircraft Price and Advance Payments.

         4.7.1 Advance Payments. An estimated CSE price will be included in the
Aircraft Advance Payment Base Price for the purpose of establishing the advance
payments for the Aircraft. The estimated price for the Boeing purchased CSE
installed on each Aircraft by Change Requests identified in Attachment C is One
Million Dollars expressed in 1995 dollars.

         4.7.2 Aircraft Price. The Aircraft Price will include the actual CSE
prices and any associated transportation costs charged Boeing by Suppliers.

4.8      Customer's Indemnification of Boeing for SPE and CSE.

         Customer will indemnify and hold harmless Boeing from and against all
claims and liabilities, including costs and expenses (including attorneys' fees)
incident thereto or incident to successfully establishing the right to
indemnification, for injury to or death of any person or persons, including
employees of Customer but not employees of Boeing, or for loss of or damage to
any property, including Aircraft, arising out of or in any way connected with
any nonconformance or defect in any SPE and CSE or in the installation thereof
or in the provision of services hereunder, and whether or not arising in tort or
occasioned in whole or in part by the negligence of Boeing. This indemnity will
not apply with respect to any nonconformance or defect caused solely by Boeing's
installation of the SPE and CSE.

                              CRITICAL PATH EVENTS



The contingency plan is the alternate course of action which will be implemented
if the critical decision date is not met or other course of action is not agreed
to by Boeing and Customer. The critical impact events listed below are
milestones which must be met by the BFE/SPE and CSE Suppliers to achieve the
in-sequence installation of the CSE. The Required Due Dates in such tables are
the dates on which Boeing begins to incur disruption costs. The Critical
Decision Dates are the dates after which the critical impact event cannot be
accomplished to maintain the delivery schedule and/or full system functionality.
A meeting to discuss a recovery plan cost impact and/or an alternate course of
action will be held within one week of knowledge of delinquency or impending
delinquency.
