    On [*] Buyer made a progress payment in an amount of [*] for the Firm
    Aircraft.

    On [*] Buyer shall make a progress payment in an amount of [*] for the
    Firm Aircraft.

    On [*] Buyer shall make a progress payment in an amount of [*] for the Firm
    Aircraft.

    On [*] Buyer shall make a progress payment in an amount of [*] for the Firm
    Aircraft.

    On [*] Buyer shall make an initial deposit in an amount of [*] for the [*]
    Option Aircraft ([*] per Option Aircraft).

    On [*] Buyer shall make an initial deposit in an amount of [*] for the [*]
    Option Aircraft ([*] per Option Aircraft).

    Buyer shall not be obligated to make any deposits or further progress
    payments for the Firm Aircraft or initial deposits for the Option Aircraft
    until the earlier of (x) [*] after the date Buyer issues shares pursuant to
    its initial public offering and (y) [*] (the "Catch Up Date").

    On the Catch Up Date, Buyer shall make any additional progress payments for
    the Firm Aircraft and all initial deposits for the Option Aircraft that
    would otherwise have been due per Article 9.1A of the Letter Agreement and
    Article 24.a to the Purchase Agreement. In order to compensate Embraer for
    the delay in such progress payments and initial deposits, interest shall
    accrue at a rate of [*] on the amount of each progress payment and initial
    deposit that has been delayed pursuant to this Amendment No. 3 for the
    duration of such delay (the "Delay PDP Interest"). The Delay PDP Interest
    payments shall be made in accordance with the provisions of Article 9.3 of
    the Letter Agreement, except that they shall be paid on the Catch Up Date
    instead of the date of delivery of an Aircraft.

    On [*] Buyer shall make an interest payment related to the delay in the
    progress payments for the Firm Aircraft and initial deposits for the Option
    Aircraft from [*] up to [*], in an amount of [*]. Therefore, the Delay PDP
    Interest above mentioned shall be calculated starting on [*]. The Delay PDP
    Interest due pursuant to this Article 1 shall be in addition to all amounts
    of interest due pursuant to Article 9 of the Letter Agreement.

    It is also understood by the Parties that this delay in progress payments
    for the Firm Aircraft as described in this Article 1 to this Amendment No. 3
    does not [*] in case of [*] (for the avoidance of doubt, [*] is [*]).

2.  MISCELLANEOUS:  All other provisions of the Agreement, which have not
    been specifically amended or modified by this Amendment No. 3, shall
    remain valid in full force and effect without any change.
