            Agreement and Attachments B and C of the Purchase Agreement

      2.    In accordance with the Purchase Agreement, Seller's assignment

            (a) Buyer is not and will not be owned, effectively controlled or
            managed by any airframe manufacturer which competes with Embraer in
            the thirty-seven (37) to seventy (70) seat turbo jet market; and

            Embraer of the identity of such entity at least thirty (30) calendar
            days prior to such transaction (provided that if Buyer fails to
            notify Embraer within this time, Buyer may not assign its remaining
            rights without Embraer's consent, which shall not be unreasonably
            withheld) and provide Embraer with prior written notice of any
            events under such agreement that would cause any rights thereby
            assigned to revert to Buyer under such agreement; provided, however,
            that, pursuant to the Embraer Purchase Agreement, Buyer shall not
            transfer the Aircraft to an entity which is owned, effectively
            controlled or managed by any airframe manufacturer which competes

            market.

      3.    Embraer hereby consents to the foregoing assignment by Seller to
            Buyer under and pursuant to the terms and conditions of this
            Assignment.

      4.    Buyer confirms, for Embraer's benefit, that in exercising any rights
            under the Embraer Purchase Agreement or in making any claim with
            respect to the Aircraft or other goods and services delivered or to
            be delivered pursuant to the Embraer Purchase Agreement, the terms
            and conditions of the Embraer Purchase Agreement shall apply to and
            bind Buyer (and any assignee of Buyer) to the same extent as Seller.

      5.    Except as stated herein, nothing contained herein shall subject
            Embraer to any liability to which it would not otherwise be subject
            under the Embraer Purchase Agreement or modify in any respect the
            rights of Embraer thereunder.

      6.    This Assignment (and the acknowledgement and consent to be signed by
            Embraer) may be executed in separate counterparts, each of which
            when so executed and delivered shall be an original and all such
            counterparts shall together constitute one and the same instrument.


                                                                               2

      7.    This Assignment shall be governed by and construed in accordance
            with the laws of the State of New York without reference to any
            choice of law rules thereof that would result in a choice of law
            other than that of New York.

                                                                               3
