                              AMENDED AND RESTATED
                           LETTER AGREEMENT GCT-026/98
--------------------------------------------------------------------------------

This Amended and Restated Letter of Agreement GCT-026/98 ("Agreement") dated
April 19, 2002, is an agreement between Republic Airways Holdings, Inc.
("Buyer") with its principal place of business at 2500 S. High School Road,
Indianapolis, Indiana 46241, United States, and Embraer - Empresa Brasileira de
Aeronautica S.A. ("Embraer"), with its principal place of business at Sao Jose
dos Campos, Sao Paulo, Brazil, relating to the Amended and Restated Purchase
Agreement GCT-025/98 dated April __, 2002 (the "Purchase Agreement") for the
purchase by Buyer of up to thirty-seven (37) new EMB-145 LR aircraft (the
"Aircraft").

This Agreement constitutes an amendment and modification of the Purchase
Agreement, and it sets forth additional agreements of the Parties with respect
to the matters set forth in the Purchase Agreement. All terms defined in the
Purchase Agreement shall have the same meaning when used herein, and in case of
any conflict between this Agreement and the Purchase Agreement, this Agreement
shall govern.

Solitair Corp. ("Solitair") has assigned to Buyer all of Solitair's rights and
obligations under the Purchase Agreement DCT-025/98 between Embraer and Solitair
(as amended before the date of the Purchase Agreement, the "Original Purchase
Agreement") and Letter Agreement GCT-026/98 dated as of June 17, 1998 between
Embraer and Solitair (as amended before the date of this Agreement, the
"Original Letter Agreement") with respect to the sale of certain unexercised
option aircraft, and in connection with such assignment, Solitair has also
assigned to Buyer its remaining rights with respect to the aircraft delivered
and to be delivered under the Original Purchase Agreement.

Buyer and Embraer now desire to amend and restate certain agreements relating to
such Aircraft, as previously provided in the Original Letter Agreement.

At the time this Agreement becomes effective, neither Buyer nor Embraer shall
have any rights against or obligations to the other pursuant to the Original
Letter Agreement.

NOW, THEREFORE, for good and valuable consideration, receipt of which is hereby
acknowledged, Embraer and Buyer agree as follows:
