	Revisions to Aircraft General Terms Agreement AGTA-DAL dated October 21, 1997 (AGTA) Terms 

		
	Reference:
	Purchase Agreement Nos. 2022, 2023, 2024, 2025 and 2026 (the Purchase Agreements) between The Boeing Company (Boeing) and Delta Air Lines, Inc. (Customer) relating to Model 737-632/-732/-832/-932ER, 757-232, 767-332/332ER, 767-432, 777-232IGW/-232ER/-232LR aircraft (Aircraft)

This letter agreement (Letter Agreement) revises and supersedes DAL-PA-02022-LA-1104472 and amends and supplements the AGTA and the Purchase Agreements.  All terms used but not defined in this Letter Agreement shall have the same meaning as in the applicable Purchase Agreement.
The 737-900ER aircraft did not exist at the time the AGTA-DAL was signed.  Customer has ordered 737-932ER aircraft and Customer and Boeing now agree to incorporate the 737-900ER model aircraft into the terms and conditions of the AGTA.  In addition, Customer has never purchased and has informed Boeing that it does not intend to purchase the 737-600 model aircraft and the parties have agreed that it should be removed from the agreement.  
IT IS AGREED:
		
	1.
	The 737-600 is no longer offerable under this Purchase Agreement.  All references to the 737-600 are hereby deleted and shall be deemed to be of no further effect. 

		
	2.
	Article 1, Definitions, Subject Matter of Sale and Annual Fleet Plan Review is amended as follows:

2.1 Airframe Price is revised to delete the word “and” after the word “737-700” and add a comma and the word “737-900ER” after the word “737-800” and now reads as follows:
“Airframe Price is defined as the price of the airframe for a model of Aircraft set forth in Table 1 to the applicable Purchase Agreement (for models 737‐700, 737‐800, 737-900ER and 777-200LR, the Airframe Price includes the Engine Price).”
2.2 Engine Price is revised to delete the word “and” after the word “737-700” and add a comma and the word “737-900ER” after the word “737-800” and now reads as follows: 
“Engine Price is defined as the price set by the engine manufacturer for a specific engine model to be installed on the model of Aircraft set forth in the Tables to the applicable Purchase Agreement (not applicable to models 737-700, 737-800, 737-900ER and 777-200LR).”

2.3 Escalation Adjustment is revised to delete the word “and” after the word “737-700” and add the word “737-900ER” after the word “737-800” and now reads as follows: 
“Escalation Adjustment is defined as the price adjustment to the Airframe and Optional Features Prices (and the Engine Price for models 737‐700, 737‐800, 737-900ER and 777-200LR) resulting from the calculation using the economic price formula contained in Exhibit D to this AGTA.”
2.4 Option Aircraft is revised to add a new sentence:  “Upon the execution of Supplemental Agreement 17 to Purchase Agreement 2022, all remaining Options and Option Aircraft under Purchase Agreement 2022 are cancelled” so that the paragraph now reads as follows: 
“Option Aircraft is defined as those Option Aircraft listed in Table 2 to the applicable Purchase Agreement and in Letter Agreement DAL-PA-02022-LA-1105858.  For historical records the Option Aircraft were initially (a) 60 model 737-632/-732/-832 Aircraft; (b) 20 model 757-232 Aircraft; (c) 10 model 767-332/-332ER Aircraft; (d) 24 model 767-432ER Aircraft; and (e) 10 model 777-232IGW Aircraft.

2.6 Rolling Option Aircraft is revised to (i) replace the scrivener reference to “Firm Aircraft” with “Rolling Option Aircraft”; and (ii) add a new sentence:  “Upon the addition of the 737-900ER model aircraft to Purchase Agreement 2022, all remaining Rolling Options and Rolling Option Aircraft under Purchase Agreement 2022 are cancelled” and now reads as follows:
“Rolling Option Aircraft is defined as those Aircraft listed in Table 2 to the applicable Purchase Agreement and are initially: (i) 280 model 737 Aircraft; (ii) 90 model 757 Aircraft; (iii) 19 model 767-300 Aircraft; and (iv) 25 model 767-400 Aircraft.  Upon the addition of the 737-900ER model aircraft to Purchase Agreement 2022, all remaining Rolling Options and Rolling Option Aircraft under Purchase Agreement 2022 are cancelled.”
