2. the renegotiation by Customer of aircraft leases with unexpired lease terms whereby Customer chooses to replace older leased aircraft with newer leased aircraft provided by one or more third parties or to reduce the number of leased aircraft in Customer's fleet, so long as after giving effect to such transactions, there is no material net increase in the lease term or the number of leased aircraft in Customer's fleet or a resulting adverse impact on Customer's acquisition of the Restructured Aircraft; or
3. aircraft currently leased by the Customer or any of its subsidiaries (including any extensions of the lease term or purchase of such aircraft).
