|1. | Revised Delivery Schedule.
|-- | --------------------------

The revised delivery
months for the Moved Aircraft are revised as specified in the new Table 1 to the Purchase Agreement, including a revised Advance Payment Base Price (APBP) for each Moved Aircraft.



|2. | Business Deal.
|-- | --------------

Notwithstanding the revised
delivery schedule set forth in Table 1, and with the exception outlined in Article 3 below, all terms and conditions applicable to each Moved Aircraft under the Purchase Agreement shall remain unchanged, but shall be adjusted appropriately to
reflect the revised delivery schedule.

***



|4. | Interest on Deferred Advance Payments.
|-- | --------------------------------------

4.1 As of
May 30, 2007, under the current delivery schedule, approximately *** in interest has accrued against deferred advance payments.

4.2
The amount of interest in paragraph 5.1 above will be adjusted in accordance with the deferred advance payment schedule set forth in paragraph 4 of reference B, based upon the revised delivery schedule.

For avoidance of doubt, the deferred interest will be frozen at the amount shown in paragraph 5.1 above until such time the revised schedule for each Slide
Aircraft falls within the standard advance payment schedule, at which time the deferred interest will once again accrue.



|5. | Confidential Treatment.

commercial and financial information contained in this Letter Agreement are considered by Boeing as confidential. Customer agrees that it will treat this Letter Agreement and the information contained herein as confidential and will not, without the

6.2 For each Aircraft Customer may elect to make advance payments in accordance with this Letter
Agreement. Once an advance payment on a particular Aircraft (other than the *** payment due upon signing of the definitive agreement) has been made as provided in the payment schedule set forth above, it will be assumed that all further advance
payments on such Aircraft will also be paid in accordance with the payment schedule above until Customer shall notify Boeing otherwise.

6.3 With respect to any advance payment made as provided in the payment schedule set forth above, the portion of the payment otherwise due on such advance payment date as provided in the payment schedule set forth in Table 1 to the Purchase
Agreement (the Originally Scheduled Payment) equal to the difference (i) between the Originally Scheduled Payment and (ii) the amount paid on such advance payment date as provided in the payment schedule set forth above shall
be deemed to be deferred until the delivery date of the Aircraft to which such payment relates.

6.4 Interest on the portion of any
Originally Scheduled Payment deemed to be so deferred will be charged at the fluctuating rate of interest per annum in effect from time to time equal to the ninety-day London Interbank Offered Rate (LIBOR) as published in The Wall Street Journal
(West Coast Edition) on the first business day of each calendar quarter, plus *** for the period from and including the applicable advance payment date to but excluding the date paid.
