                        for any delays in the delivery of an AIRCRAFT or in the
                        performance of any act to be performed by EMBRAER under

                        the following events or occurrences hereinafter referred
                        to as "excusable delays" (a) force majeure (including,
                        but not limited to, war or state of war, civil war,
                        insurrection, fire, accident, explosion, flood, act of

                        strike, labor troubles); (b) inability despite due and

                        accessories, parts or means of transport; or (c) any
                        delay resulting from any failure by BUYER to perform any
                        action or provide any information contemplated by this
                        Agreement or delays resulting from any other cause to
                        the extent it is beyond EMBRAER's control or does not
                        result from EMBRAER's fault or negligence.

                2.      Within sixty (60) calendar days after the occurrence of
                        any of the above-mentioned events which constitute
                        causes of excusable delays in delivery of an AIRCRAFT or

                        under this Agreement, EMBRAER undertakes to send a
                        written notice to BUYER, with requested acknowledgment
                        of receipt, including a description of details involved

                        AIRCRAFT by the same number of calendar days required
                        for the cause of delay to be remedied. EMBRAER
                        undertakes to use its best efforts whenever applicable
                        to avoid or remove any such causes of delay and to
                        minimize their effect on the CONTRACTUAL DELIVERY DATE
                        of an AIRCRAFT-

                4.      If the cause of such excusable delays is such as to last
                        longer than three hundred (300) calendar days or to
                        render the performance of this Agreement impossible,
                        then this Agreement shall be considered terminated
                        without liability to either party, except as provided
                        for in Article 22-b hereof.

                        after the CONTRACTUAL DELIVERY DATE for such AIRCRAFT,
                        BUYER will be entitled to claim from EMBRAER liquidated
                        damages equal to US$ 5,000.00 (five thousand US Dollars)
                        per day, for each calendar day of delay in excess of the

                        EMBRAER notices BUYER such AIRCRAFT will be ready for

                        PRICE of the delayed item.

                2.      The grace period of ten (10) calendar days granted by
                        BUYER to EMBRAER as mentioned herein shall only prevail
                        should BUYER receive a written notification from EMBRAER
                        advising the expected delay and provided such written
                        notification is presented to BUYER forty (40) calendar
                        days prior to the relevant AIRCRAFT CONTRACTUAL DELIVERY
                        DATE.

                        liquidated damages.

        C.      DELAY DUE TO LOSS OR STRUCTURAL DAMAGE OF THE AIRCRAFT:

                Should any AIRCRAFT be destroyed or damaged before its
                acceptance to the extent that it becomes commercially useless,
                BUYER may, at its sole discretion, either take a replacement
                AIRCRAFT at a later delivery date to be agreed by the PARTIES or
                terminate this Agreement with respect to such AIRCRAFT by notice
                to EMBRAER given in accordance with Article 24 hereof, without
                any liability to either party.

22.     TERMINATION:

        a.      Should either party fail to comply partially or completely with
                its obligations hereunder, the other party shall be entitled to
                give notice of such failure and to require that such failure be
                remedied within the period specified in that notice, which
                period shall not be less than five (5) calendar days. Should
                such failure not be remedied within the period so specified,
                then the party who gave notice of such failure shall be entitled
                to terminate this Agreement provided always that the foregoing
                shall not apply in any circumstances where a specific right of
                termination is available or will be available upon the expiry of
                a specific period of time. Should termination occur in
                accordance with the foregoing, the defaulting party shall pay to
                the non-defaulting party, as liquidated damages, an amount
                determined by mutual agreement or by law.

        b.      BUYER shall have the right to terminate this Agreement, in
                respect to the relevant AIRCRAFT, upon the occurrence of any
                excusable delay of three hundred (300) calendar days or longer
                and any non-excusable delay of ninety (90) calendar days or
                longer after such AIRCRAFT CONTRACTUAL DELIVERY DATE. Such right
                to be exercisable by giving EMBRAER a written notice to such
                effect no earlier than the three hundredth (300th) or ninetieth
                (90th) calendar day as applicable. Upon receipt of such notice
                of termination, EMBRAER shall return to BUYER an amount equal to
                the amounts previously paid by BUYER relative to the relevant
                AIRCRAFT less the value of equipment or services previously
                delivered or performed by EMBRAER, it being hereby agreed by the
                PARTIES that, in this case, no kind of other indemnity shall be
                due by EMBRAER to BUYER.

        C.      In the event of a force majeure occurring prior to the ACTUAL
                DELIVERY DATE of any AIRCRAFT which causes BUYER to determine
                not to purchase such AIRCRAFT, BUYER may by written notice to
                EMBRAER, terminate the Purchase Agreement with respect to such
                AIRCRAFT, and BUYER shall only be liable to EMBRAER for the
                following amounts on account of such AIRCRAFT:

        d.      EMBRAER agrees that BUYER has the option to terminate the
                Purchase Agreement with no penalty assessed against BUYER by
                EMBRAER, in the event EMBRAER fails to deliver any six (6)
                consecutive AIRCRAFT due to force majeure reasons (and in case
                of this item "d", excluding acts of government, governmental
                priorities, requisition, strike and labor troubles from the
                concept of force majeure) and/or if such delay is due to reasons
                detailed in Article 1O.a.1 (b) (except to the extent that the
                delay is as a consequence of a general work force strike of
                EMBRAER or of a supplier of EMBRAER, if the supplier provides to
                EMBRAER a major component of the AIRCRAFT) and for which Article
                22.c has not been invoked, within sixty (60) days of each
                relevant AIRCRAFT CONTRACTUAL DELIVERY DATE as specified in
                Article 6 herein. If EMBRAER fails to deliver any six (6)
                consecutive AIRCRAFT within such sixty (60) day period as above
                mentioned, BUYER's right to terminate the Purchase Agreement may
                be exercised by written notice to EMBRAER as provided in Article
                25 herein, within five (5) days after the expiration of the
                sixty (60) day period following the CONTRACTUAL DELIVERY DATE of
                the third consecutive AIRCRAFT delayed more than sixty (60)
                days. In this case, all amounts paid by BUYER to EMBRAER under
                the Purchase Agreement, and specifically with regard to the
                non-delivered AIRCRAFT, shall be returned to BUYER, less the
                value of equipment or services previously delivered or performed
                by EMBRAER, it being hereby agreed by the PARTIES that, in this
                case, no other kind of indemnity shall be due by EMBRAER to
                BUYER.

        e.      If EMBRAER terminates this Agreement pursuant to Article 7.g
                hereof, EMBRAER may, at its sole option, retain all amounts
                previously paid by BUYER as liquidated damages resulting from
                such default on the part of BUYER.
