All purchase right aircraft are offered on a subject-to-availability-of-position
(STAP) basis, and will retain the same Model 737-8EH configuration and detail
specification as that described in Exhibit A to the Purchase Agreement, with the
exception of any detail special feature changes as may be mutually agreed. With
the firm exercise of each purchase right, Boeing offers Customer the ability to
add a one-for-one additional purchase right aircraft, to a maximum of six (6)
such additional purchase right aircraft, with any such additional purchase right
aircraft to also be STAP and exercised not later than 01 June 2009 for delivery
not later than 31 December 2010. Should Customer choose not to exercise some or
all of the offered purchase right aircraft in any given calendar year, such
un-exercised purchase right aircraft will be cancelled and not be available for
later exercise.

3.    Purchase Right Aircraft Exercise and Business Terms.

Customer may exercise a purchase right aircraft by providing Boeing with written
notice not later than the first business day of the exercise month above
described, which will be not less than fifteen (15) months prior to the
requested aircraft delivery position, with not more than two (2) requested
aircraft to be delivered in any one month. Boeing will, within thirty (30) days
of Customer's notice to exercise a purchase right aircraft, notify Customer of
the availability of such requested delivery position as well as alternative
delivery positions, and within such thirty (30) day period the Purchase
Agreement will be amended to incorporate the agreed upon additional firm
purchased aircraft.

The same base price and business terms as those described in the reference
Purchase Agreement will apply to any such model 737-8EH purchase right aircraft
delivering before 31 December 2010. However, Boeing does retain the right to
increase the basic aircraft price to accommodate any mandated government or
other changes made necessary for reasons of improving safety-of-flight and/or
retention of the aircraft certificate of airworthiness.

At the time of Customer's exercise of a purchase right aircraft, such aircraft
will then become a firmly contracted aircraft and will require Customer's
payment within 5 business days any advance payments due at time of exercise, per
the terms of the Purchase Agreement and/or Letter Agreement No, 6-1162-DME-0707
as well as any further advance payments as may be due per the terms of the
advance payment schedule described therein.

4.    Firm Aircraft Termination - Excusable Delay.

If any firm Aircraft are terminated by Boeing from this Purchase Agreement under
Article 7, Excusable Delay, the number of Purchase Right Aircraft available to
Customer under this Letter Agreement shall remain unchanged. If any firm
Aircraft are terminated by Customer from this Purchase Agreement under Article
