This Purchase Agreement No. 2484 dated as of December 29, 2004 between The

formerly known as Continental Airlines, Inc.) (Customer) relating to the
purchase and sale of Model 787 aircraft together with all tables, exhibits,
supplemental exhibits, letter agreements and other attachments thereto, if any,
(Purchase Agreement) incorporates and amends the terms and conditions of the

parties, identified as AGTA-CAL (AGTA).

 

Article 1. Quantity, Model, Description and Inspection.

The aircraft to be delivered to Customer will be designated as Model 787

process (787 Inspection Process) which will apply in lieu of inspection
processes traditionally applicable to other models of aircraft and will
supersede the provisions of Article 5.2 of the AGTA.

 

Article 2. Delivery Schedule.

The Aircraft will be delivered to Customer in accordance with the scheduled
months of delivery of the Aircraft listed in the attached Table 1. Exhibit B

payments which are past due in accordance with the standard advance payment
schedule set forth in paragraph 4.2 above.

4.4 Customer will pay the balance of the Aircraft Price of each Aircraft at
delivery. The Aircraft Price for each Aircraft will be re-calculated at the time
that Aircraft is delivered using the then available escalation factors for the
month when that Aircraft is delivered to calculate the Escalation Adjustment as
defined in Supplemental Exhibit AE1.

 

Article 5. Additional Terms.

5.1 Excusable Delay. Article 7.1 of the basic articles of the AGTA in so far as

and not occasioned by Boeing’s fault or negligence. A delay resulting from any
such cause is defined as an Excusable Delay.
