         3. Section 3.01 of the Agreement is amended by deleting the third

         Delivery of each Aircraft shall be made (i) at the option of American,
         (A) at Dallas/Fort Worth International Airport ("DFW") or TUL (as
         defined in Section 3.02(a)) or (B) at an airport in the State of Nevada
         if American so advises FedEx at least seven (7) days prior to the
         Scheduled Delivery Date for such Aircraft, or (ii) at such other
         location on FedEx's route system as American designates in 



<PAGE>   2

         writing to FedEx at least ninety (90) days prior to the Scheduled
         Delivery Date and to which FedEx consents, such consent not to be
         unreasonably withheld.

         4. Section 3.02 of the Agreement is amended by adding and inserting

         7. Attachment 2 to Exhibit B, Aircraft Delivery Certificate, is amended
by deleting Attachment 2 attached to Exhibit B in its entirety and replacing it

         4. This Amendment may be executed in several counterparts, all of which
shall be deemed an original, and all such counterparts shall constitute one and
the same instrument.
