days following option exercise, either party may terminate the option to purchase such Option Aircraft by giving written notice to the other within five (5) days. If Customer and Boeing, having acted diligently and in good faith, fail to enter
into the Definitive Agreement, Boeing will retain the Option Deposit for that Option Aircraft and shall have no further obligation with respect to that Option Aircraft.

9. Assignment.
