2.4           Upon
conversion of a Purchase Right Aircraft into an Option Aircraft, Buyer shall
wire transfer the Deposit of *** to Boeing and Boeing and Buyer shall agree on a

amended accordingly.  In the event Buyer thereafter exercises its
right to purchase such Option Aircraft, application of the Deposit will be in
accordance with Article 4.1 herein. If the conversion is a Purchase Right
Aircraft to a firm Aircraft, Buyer shall wire transfer any advance payments due
under the Agreement.

     

                    
2.5          Buyer and Boeing
will consult on a frequent basis to keep each other informed as to Buyer’s fleet

    4.           Option Aircraft
Payment.

    

    4.1           In
consideration of the granting of the Options as set forth herein, on or before
the date Boeing and Buyer enter into a definitive agreement to purchase the
Aircraft, Buyer will pay a deposit to Boeing of *** for each Option Aircraft
(Deposit).  In the event Buyer exercises its Options herein, the
amount of the Deposit will be credited against the first advance payment due for
such Option Aircraft pursuant to the advance payment schedule set forth in
paragraph 3 of Attachment A.  The Deposits for the Option
Aircraft will be refunded to Buyer, without interest, if the parties do not
enter into a definitive Agreement for the Aircraft.

    

    In the
event that, after the parties enter into a definitive agreement to purchase the
Aircraft, Buyer does not exercise its Options to purchase the Option Aircraft
pursuant to the terms and conditions set forth herein, Boeing will be entitled
to retain the Deposits for the Option Aircraft except as provided in paragraph 6
herein.

    

    4.2           Advance
payments in the amount of *** of the advance payment base price will be payable
on the Option Aircraft in accordance with paragraph 3 of
Attachment A.  The remainder of the Option Aircraft purchase
price is due at the time of delivery of the Option Aircraft.

    

    5.           Option
Exercise.

    

    5.1           To
exercise its Option, Buyer will give written or telegraphic notice thereof to
Boeing on or before sixteen (16) months prior to the first day of the delivery
month of each Option Aircraft.

    

    In such
notice Buyer will select the Option Model type, and the applicable delivery
positions.  Table 2 of the Agreement lists the Option Exercise
dates.

    

    5.2           It
is understood and agreed that Boeing may accelerate the Option exercise dates
specified above if Boeing must make production decisions which are dependent on
Buyer's decision to buy the Option Aircraft.  If Boeing elects to
accelerate the Option exercise dates, Boeing will do so by giving written or
telegraphic notice thereof to Buyer.  Such notice will specify the
revised Option exercise dates, which will not be earlier than 30 days after the
date of transmittal of such notice, and the Option Aircraft delivery positions
affected by such revision.  If Buyer fails to exercise its Option for
any Option Aircraft affected by such revised dates, the Deposit applicable to
such Option Aircraft will be promptly refunded, with interest, to
Buyer.  The interest rate for calculation of the interest associated
with such refund is the rate of two percent (2%) below the Citibank base rate in
effect from time to time during the period the Option deposit is held by
Boeing.

    6.           Contract
Terms.

    

    It is understood that Boeing and Buyer
will use their best efforts to enter into a definitive agreement for the Option
Aircraft within thirty (30) days after Buyer exercises an Option to purchase
Option Aircraft pursuant to paragraph 5 covering the detailed terms and
conditions for the sale of such Option Aircraft.

    

    Such
definitive agreement will include the terms and conditions contained herein
together with the terms and conditions, not inconsistent herewith, contained in
Boeing's then-current standard form of purchase agreement for the sale of Model
737-700 aircraft in effect as of the date of Option exercise and such additional
terms and conditions as may be mutually agreed upon.  In the event the
parties have not entered into such an agreement within the time period
contemplated herein, either party may, exercisable by written or telegraphic
notice given to the other within thirty (30) days after such period, terminate
the purchase of such Option Aircraft.

    

    7.           Termination of Option to
Purchase.

    

    Either Boeing or Buyer may terminate
the Options to purchase an Option Aircraft if any of the following events are
not accomplished by the respective dates contemplated in this letter agreement,
or in the Agreement, as the case may be:

    

    (i)           termination
of the purchase of the Aircraft under the Agreement for any reason;

    

    (ii)          payment
by Buyer of the Deposit with respect to an Option Aircraft pursuant to paragraph
4.1 herein;

    

    (iii)         exercise
of an Option to purchase an Option Aircraft pursuant to the terms
hereof.

    Any
termination of an Option to purchase by Boeing which is based on the termination
of the purchase of Aircraft under the Agreement will be on a one-for-one basis,
for each Aircraft so terminated.

    

    Any
cancellation of an Option to purchase which is based on failure to make the
required Deposit or to exercise the Option to purchase shall only apply to the
Option Aircraft so canceled.

    

    Termination
of an Option to purchase provided by this letter agreement will be caused by
either party giving written notice to the other within 10 days after the
applicable date.  Upon receipt of such notice, all rights and
obligations of the parties with respect to an Option Aircraft for which the
Option to purchase has been terminate will thereupon terminate.

    

    If
termination is result of a revision of an Option exercise date by Boeing
pursuant to paragraph 5.2, Boeing will promptly refund to Buyer, with
interest, any payments received from Buyer, including the Deposit, with respect
to the Option Aircraft for which the Option is terminated.  If
termination is for any other reason, Boeing will promptly refund to Buyer,
without interest, any payments received from Buyer with respect to the affected
Option Aircraft, except the Deposit, which Buyer may apply to any model Boeing
aircraft purchased by Buyer from Boeing at a future date.

    1.2           Changes.  The
Detail Specification will be revised to include:

    

    (1)           Changes
applicable to the basic Model 737-700 aircraft which are developed by Boeing

mutually agreed upon.

configuration, including BFE/SPE vendor selection fifteen (15) months prior to
delivery of each Option Aircraft.  If such items are not resolved by
the indicated dates, Boeing reserves the right to amend this letter
agreement:

    

    (i)           to
adjust the scheduled delivery of the Option Aircraft to a later time period
and,

    

    (ii)                      to
make such other changes as are appropriate and consistent with the revised
Option Aircraft deliveries.

    

    1.3           Effect of
Changes.  Changes to the Detail Specification incorporated
pursuant to the provisions of the clauses above will include the effects of such
changes upon Option Aircraft weight, balance, design and
performance.  Performance guarantees for the Option Aircraft which are
mutually acceptable to the parties will be included in the definitive agreement
