NOW THEREFORE, in consideration of the mutual covenants herein contained, the Parties agree that the following provisions of Letter Agreement No. 1 shall

 “5.
Assignability of Allowance 
 Any allowance described herein is exclusively for the benefit of Airline and is not assignable without
CFM’s written consent; provided that Airline may assign such allowance, together with its other rights under this Letter Agreement on the terms described in clause (i) of Paragraph A of the Agreement. 

CFM agrees that in the event Airline seeks financing for payment of predelivery payments (“PDP Financing”) for the Aircraft,
CFM will consent to the assignment to such Lender of ***** of the Aircraft Allowance per A. (i) above for Aircraft in this Letter Agreement. 

CFM agrees that in the event Airline enters into a lease agreement with a lessor for any of the Aircraft that include Engines and such Engines
are enrolled in a long term CFM rate per Flight Hour engine maintenance program (“RPFH agreement”) between Airline and CFM, CFM will act in good faith to reach a mutually acceptable tri-partite agreement among CFM, Airline and the
lessor whereby the Engine warranties, all dollar amounts collected by CFM for the Engines in accordance with the RFPH agreement and Airline’s other benefits under the RPFH Agreement will be fully assignable to the lessor (and subsequent
operators, if any) in the event Airline defaults under the lease agreement and lessor takes possession of the Aircraft.”
