         2.       Letter of Transmittal;

UNLESS EXTENDED.

         The Exchange Offer is not conditioned upon any minimum number of Old
Notes being tendered.

         To participate in the Exchange Offer, a beneficial holder must cause a
DTC Participant to tender such holder's Old Notes to Bankers Trust Company (the
"Exchange Agent") account maintained at the Depository Trust Company ("DTC") for
the benefit of the Exchange Agent through DTC's Automated Tender Offer Program

of itself and the beneficial owners of tendered Old Notes 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 Notes will
represent to AerCo that (i) the New Notes acquired in the Exchange Offer are
being obtained in the ordinary course of business of the person receiving such
New Notes, whether or not such person is such holder, (ii) neither the holder of
the Old Notes nor any such other person has an arrangement or understanding with
any person to participate in the distribution of such New Notes, (iii) if the
holder is not a broker-dealer or is a broker-dealer but will not receive New
Notes for its own account in exchange for Old Notes, neither the holder nor any
such other person is engaged in or intends to participate in a distribution of
the New Notes and (iv) neither the holder nor any such other person is an
"affiliate" of AerCo within the meaning of Rule 405 under the Securities Act of
1933, as amended. If the tendering holder is a broker-dealer that will receive
New Notes for its own account pursuant to the Exchange Offer, you will represent
on behalf of such broker-dealer that the Old Notes to be exchanged for the New
Notes were acquired by it as a result of market-making activities or other
trading activities, and acknowledge on behalf of such broker-dealer that it will
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of such New Notes. By acknowledging that it will
deliver and by delivering a prospectus meeting the requirements of the
Securities Act in connection with any resale of such New Notes, such
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

         The enclosed Instruction to the Book-Entry Transfer Participant from
Owner contains an authorization by the beneficial owners of the Old Notes for
you to make the foregoing representations.

         AerCo will not pay any fee or commission to any broker or dealer or to
any other persons (other than the Exchange Agent) in connection with the
solicitation of tenders of Old Notes pursuant to the Exchange Offer. MSAF will
pay or cause to be paid any transfer taxes payable on the transfer of Old Notes
to it, except as otherwise provided in Instruction 5 of the enclosed Letter of
Transmittal.
