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

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.

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”
