WHEREAS, Lessor has recently purchased a third aircraft which it desires to make available for use by the Lessee under the Agreement; and

WHEREAS, Lessor and Lessee have agreed to modify the Agreement as hereinafter set forth in this First Amendment.

NOW, THEREFORE, in consideration of the above recitals, and the mutual covenants herein contained and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged by both parties, it is mutually understood and agreed that the Agreement be amended a follows:

WHEREAS, Lessor is legal owner of two aircraft (“Aircraft”), equipped with engines and components as described in the Aircraft Subject to the Time Sharing Agreement attached hereto and made a part hereof, as Exhibit A and C;
