		  	BOEING PROPRIETARY	  	

 Purchase Agreement No. 2484 

between 
 The
Boeing Company 
 and 
 United Airlines, Inc. 
  

 
 This Purchase

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 Aircraft General

	Article 1.	Quantity, Model, Description and Inspection. 

 The aircraft to be delivered to Customer will be designated as Model 787 aircraft (the Aircraft). Boeing will manufacture and sell to Customer Aircraft conforming to the configuration

	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 describes certain responsibilities for both Customer and Boeing in order to accomplish the delivery

	Article 4.	Payment. 

 4.1 Boeing

for the Aircraft. Additional advance payments for each Aircraft are due as specified in and on the first business day of the months listed in the attached Table 1. 
 4.3 For any Aircraft whose scheduled month of delivery is less than 24 months from the date of this Purchase Agreement, the total amount of advance payments due for payment upon signing of this Purchase
Agreement will include all advance 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

2, 3 and 4 with respect to (i) quantity of Aircraft, (ii) applicable Detail Specification for the Aircraft, (iii) month and year of scheduled deliveries of the Aircraft, (iv) Aircraft Basic Price, (v) escalation factors
