Subject: Option Aircraft

This Letter Agreement amends Purchase Agreement No. 1810 dated as of January 19, 1994 (the Agreement) between The Boeing Company (Boeing) and Southwest Airlines Co. (Buyer) relating to Model 000‑0X0 aircraft (Aircraft).

All terms used and not defined herein will have the same meaning as in the Agreement.

In consideration of the purchase by Buyer of the Aircraft, Boeing hereby agrees to manufacture and sell to Buyer and Buyer shall have the option to purchase (Option or Options) the additional Model 000‑0X0 aircraft as described in paragraph 1 of Attachment A hereto and listed in Attachment B hereto (Option Aircraft).

1.    Delivery of Option Aircraft.

The Option Aircraft will be delivered to Buyer during or before the months set forth in Attachment B to this Letter Agreement.

2.    Price.

2.1    The advance payment base prices of the Option Aircraft are set forth in Attachment B to this Agreement. The Option Aircraft pricing elements and associated pricing terms and conditions are given in Attachment A to this Letter Agreement.

2.2    The Advance Payment Base Prices of the Option Aircraft identified in Attachment B to this Letter Agreement do include an amount for special features in addition to those specifically described in Attachment A but do not include any amount for items of Buyer Furnished Equipment (BFE). An estimate for typical special features is *** per Option Aircraft (expressed in 2011 STE dollars). Attachment B to this Letter Agreement lists the Advance Payment Base Price per Option Aircraft.

2.3    The Option Aircraft purchase price will be the applicable basic price thereof at the time of Option Aircraft delivery adjusted in accordance with Boeing's Aircraft escalation provisions contained in the definitive agreement to purchase the Option Aircraft.

3.    Option Aircraft Payment.

3.1    In consideration of the granting of the Options as set forth herein, on the date of execution of this Letter Agreement, 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 the definitive agreement for such Option Aircraft. In the event that 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 4 herein.

3.2    Unless otherwise agreed by the parties, advance payments in the amount of *** of the advance payment base price will be payable on the Option Aircraft in accordance with Attachment B of this Letter Agreement. The remainder of the Option Aircraft purchase price is due at the time of delivery of the Option Aircraft.

4.    Option Exercise.

4.1    To exercise its Option, Buyer will give written or telegraphic notice thereof to Boeing on or before eighteen (18) months prior to the first day of the delivery month of each Option Aircraft.

4.2    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.

5.    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 4 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,

BOEING PROPRIETARY

exercisable by written or telegraphic notice given to the other within thirty (30) days after such period, terminate the purchase of such Option Aircraft.

6.    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 3.1 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.
