that acknowledges and agrees to be bound by the terms of the Letter of
Transmittal. By complying with DTC's ATOP procedures with respect to the
Exchange Offer, the DTC Participant confirms on behalf of itself and the
beneficial owners of tendered Old Certificates all provisions of the Letter of
Transmittal applicable to it and such beneficial owners as fully as if it
completed, executed and returned the Letter of Transmittal to the Exchange
Agent.

     Pursuant to the Letter of Transmittal, each holder of Old Certificates will
represent to Airplanes Group that (i) the New Certificates acquired in the
Exchange Offer are being obtained in the ordinary course of business of the
person receiving such New Certificates, whether or not such person is such
holder, (ii) neither the holder of the Old Certificates nor any such other

contains an authorization by the beneficial owners of the Old Certificates for
you to make the foregoing representations.
