4.Other Letter Agreements.
Boeing and Customer acknowledge that as they work together to develop the 737-8 program and as Boeing refines the definition of the Aircraft and associated production processes, there may be a need to execute additional letter agreements or amend letter agreements addressing one or more of the following:
4.1 Software. Additional provisions relating to software and software loading.

5.Confidentiality.
Customer understands that certain commercial and financial information contained in this Letter Agreement is considered by Boeing as confidential and has value precisely because it is not available generally to other parties. Customer agrees to limit the disclosure of the contents of this Letter Agreement to (a) its directors and officers, (b) employees of Customer with a need to know the contents for performing its

7. Corrections Performed by Customer or Its Authorized Agent.
7.1 Facilities Requirements. Provided Customer, its Authorized Agent or its third party contractor, as appropriate, are certified by the appropriate Civil Aviation Authority or Federal Aviation Authority, Customer or its Authorized Agent may, at its option, Correct defective Boeing Products at its facilities or may subcontract Corrections to a third party contractor.
7.2 Technical Requirements. All Corrections done by Customer, its Authorized Agent or a third party contractor must be performed in accordance with Boeing's applicable service manuals, bulletins or other written instructions, using parts and materials furnished or approved by Boeing.
7.3 Reimbursement.
7.3.1 Boeing will reimburse Customer’s reasonable costs of Direct Materials and Direct Labor by credit memorandum (excluding labor hours expended for overhaul) at Customer’s Warranty Labor Rate to Correct a defective Boeing Product. Claims for reimbursement must contain sufficient information to substantiate Direct Labor hours expended and Direct Materials consumed. Customer or its Authorized Agent may be required to produce invoices for materials.
7.3.2 Customer’s established Warranty Labor Rate will be the greater of the standard labor rate or one hundred fifty percent (150%) of Customer's Average Direct Hourly Labor Rate. The standard labor rate paid by Boeing to its customers is established and published annually. Prior to or concurrently with submittal of Customer's first claim for Direct Labor reimbursement, Customer may notify Boeing of Customer's then current Average Direct Hourly Labor Rate and thereafter notify Boeing of any material change in such rate. Boeing will require information from Customer to substantiate such rates.
7.3.3 Reimbursement for Direct Labor hours to perform Corrections stated in a service bulletin will be based on the labor estimates in the service bulletin.
7.3.4 Boeing will provide to Customer a single, lump sum credit memorandum for Customer’s Direct Labor hours expended to incorporate the Corrections (other than of random anomalies) identified in service bulletins and service letters in all in-warranty aircraft covered by such service bulletins or service letters after Customer’s submission of a warranty claim and verification of the incorporation of such Corrections with respect to the first affected in-warranty aircraft. Such credit memoranda will not be provided in response to any other requests for reimbursement including, without limitation, those arising out of program letters or other special offers provided by Boeing.
7.3.5 Boeing will reimburse Customer’s freight charges associated with a Correction of a defect on a Boeing Product performed by its Authorized Agent or a third party contractor.
7.3.6 Maximum Reimbursement. Unless previously agreed in writing, the maximum reimbursement for Direct Labor and Direct materials for repair of a defective Boeing Product will not exceed 65% of Boeing’s then current sales price for a new replacement Boeing Product. Inspection, removal, reinstallation labor, final testing, inspection and transportation costs are separate and are not to be included in the cost

SWA-AGTA-EXC | EXC Page 7

elements used to determine the 65% limit. By mutual agreement between Customer and Boeing, Boeing may provide a replacement Product to Customer in lieu of credit reimbursement.
7.4 Disposition of Defective Boeing Products Beyond Economical Repair.
7.4.1 A defective Boeing Product found to be beyond economical repair (see paragraph 7.3.6) will be retained for a period of thirty (30) days from the date Boeing receives Customer's claim. During the thirty (30) day period, Boeing may request return of such Boeing Products for inspection and confirmation of a defect.
7.4.2 After the thirty (30) day period, a defective Boeing Product with a value of Four Thousand dollars ($4,000) or less may be scrapped without notification to Boeing. Boeing will reimburse Customer or its Authorized Agent for the charge for any item determined to be defective under this Aircraft General Terms Agreement. If such Boeing Product has a value greater than Four Thousand dollars ($4,000), Customer must obtain confirmation of unrepairability by Boeing's on-site field service representative prior to scrapping. Confirmation may be in the form of the representative's signature on Customer's claim or through direct communication between the representative and Boeing Warranty.
8. Corrections Performed by Boeing.
8.1 Freight Charges. Customer or its Authorized Agent will pre-pay freight charges to return a Boeing Product to Boeing. If during the period of the applicable warranty Boeing determines the Boeing Product to be defective, Boeing will pre-pay shipping charges to return the Corrected Boeing Product. Boeing will reimburse Customer or its Authorized Agent for freight charges for Boeing Products returned to Boeing for Correction and determined to be defective.
8.2 Customer Instructions. The documentation shipped with the returned defective Boeing Product may include specific technical instructions for additional work to be performed on the Boeing Product. The absence of such instructions will evidence Customer's authorization for Boeing to perform all necessary Corrections and work required to return the Boeing Product to a serviceable condition.
8.3 Correction Time Objectives.
8.3.1 Boeing's objective for making Corrections is ten (10) working days for avionics and electronic Boeing Products, thirty (30) working days for Corrections of other Boeing Products performed at Boeing's facilities and forty (40) working days for Corrections of other Boeing Products performed at a Boeing subcontractor's facilities. The objectives are measured from the date Boeing receives the defective Boeing Product and a valid claim to the date Boeing ships the Corrected Boeing Product.
8.3.2 If Customer has a critical parts shortage because Boeing has exceeded a Correction time objective and Customer has procured spare Boeing Products for the defective Boeing Product in quantities shown in Boeing's Recommended Spare Parts List then Boeing will either expedite the Correction or provide an interchangeable Boeing Product, on a no charge loan basis, until the Corrected Boeing Product is returned.
8.4 Title Transfer and Risk of Loss.
8.4.1 Title to and risk of loss of any Boeing Product returned to Boeing will at all times remain with Customer or any other title holder of such Boeing Product. While

SWA-AGTA-EXC | EXC Page 8

Boeing has possession of the returned Boeing Product, Boeing will have only such liabilities as a bailee for mutual benefit would have but will not be liable for loss of use.
8.4.2 If a Correction requires shipment of a new Boeing Product, then at the time Boeing ships the new Boeing Product, title to and risk of loss for the returned Boeing Product will pass to Boeing, and title to and risk of loss for the new Boeing Product will pass to Customer.
9. Returning an Aircraft.
9.1 Conditions. An aircraft may be returned to Boeing's facilities for Correction only if:
(i) Boeing and Customer agree a covered defect exists;
(ii) Customer lacks access to adequate facilities, equipment or qualified personnel to perform the Correction; and
(iii) it is not practical, in Boeing's estimation, to dispatch Boeing personnel to perform the Correction at a remote site.

Subject to the conditions of Article 9.1, Boeing will reimburse Customer for the costs of fuel, oil, other required fluids and landing fees incurred in ferrying the aircraft to Boeing and back to Customer's facilities. Customer will minimize the length of both flights.
9.3 Separate Agreement. Prior to the return of an aircraft to Boeing, Boeing and Customer will enter into a separate agreement covering return of the aircraft and performance of the Correction. Authorization by Customer for Boeing to perform additional work that is not part of the Correction must be received within twenty-four (24) hours of Boeing’s request. If such authorization is not received within twenty-four (24) hours, Customer will be invoiced for work performed by Boeing that is not Part of the Correction.
10. Insurance.
The provisions of Article 8.2 "Insurance", of this AGTA, will apply to any work performed by Boeing in accordance with Customer's specific technical instructions to the extent any legal liability of Boeing is based upon the content of such instructions.

If Boeing determines that the Interface Problem is primarily attributable to the design or installation of any Boeing Product, Boeing will Correct the design or workmanship to the extent of any then existing obligations of Boeing under the provisions of the applicable Boeing Product warranty.
3.Supplier Responsibility.
If Boeing determines that the Interface Problem is primarily attributable to the design or installation of a Supplier Product, Boeing will assist Customer in processing a warranty claim against the Supplier.
4.Joint Responsibility.
If Boeing determines that the Interface Problem is partially attributable to the design or installation of a Boeing Product and partially to the design or installation of a Supplier Product, Boeing will seek a solution to the Interface Problem through the cooperative efforts of Boeing and the Supplier and will promptly advise Customer of the resulting corrective actions and recommendations.
5.General.
Customer will, if requested by Boeing, assign to Boeing any of its rights against any supplier as Boeing may require to fulfill its obligations hereunder.

Exhibit B
AIRCRAFT DELIVERY REQUIREMENTS AND RESPONSIBILITIES
relating to
BOEING MODEL 737-8 and 737-7 AIRCRAFT

Both Boeing and Customer have certain documentation and approval responsibilities at various times during the construction cycle of Customer’s Aircraft that are critical to making the delivery of each Aircraft a positive experience for both parties. This Exhibit B documents those responsibilities and indicates recommended completion deadlines for the actions to be accomplished.
1.GOVERNMENT DOCUMENTATION REQUIREMENTS.
Certain actions are required to be taken by Customer in advance of the scheduled delivery month of each Aircraft with respect to obtaining certain government issued documentation.
1.1 Airworthiness and Registration Documents. Not later than six (6) months prior to delivery of each Aircraft, Customer will notify Boeing of the registration number to be painted on the side of the Aircraft. In addition, and not later than three (3) months prior to delivery of each Aircraft, Customer will, by letter to the regulatory authority having jurisdiction, authorize the temporary use of such registration numbers by Boeing during the pre-delivery testing of the Aircraft.
Customer is responsible for furnishing any Temporary or Permanent Registration Certificates required by any governmental authority having jurisdiction to be displayed aboard the Aircraft after delivery.
1.2 Certificate of Sanitary Construction.
1.2.1 U.S. Registered Aircraft. Boeing will obtain from the United States Public Health Service, a United States Certificate of Sanitary Construction to be provided by Boeing to Customer and displayed aboard each Aircraft after delivery to Customer.
1.2.2 Non-U.S. Registered Aircraft. If Customer requires a United States Certificate of Sanitary Construction at the time of delivery of the Aircraft, Customer will give written notice thereof to Boeing at least three (3) months prior to deliver y. Boeing will then use commercially reasonable efforts to obtain the Certificate from the United States Public Health Service and present it to Customer at the time of Aircraft delivery. The above Boeing obligation only applies to commercial passenger-configured aircraft.
1.3 Customs Documentation.
1.3.1 Import Documentation. If the Aircraft is intended to be exported from the United States, Customer must notify Boeing not later than three (3) months prior to delivery of each Aircraft of any documentation required by the customs authorities or by any other agency of the country of import.

References: | 1) | Purchase Agreement No. PA-03729 (Purchase Agreement) between The Boeing Company (Boeing) and Southwest Airlines Co. (Customer) relating to Model 737-8 and 737-7 aircraft (Aircraft)
| 2) | Letter Agreement SWA-PA-03729-LA-1106469R1, [***] |

This letter agreement (Letter Agreement) amends and supplements the Purchase Agreement. All capitalized terms used but not defined in this Letter Agreement will have the same meaning as in the Purchase Agreement.
1. Service Ready Operational Validation.
In order to ensure that the Aircraft is ready for entry into service upon delivery, Boeing and Customer will implement a service ready operational validation program (SROV) which will aid in validating the combination of the Aircraft, support products and services as well as Customer’s own preparation for entry into service. The SROV will use [***]
to accomplish the validation.
2. Validation Planning and Execution.
2.1 The SROV Plan will be carried out over the course of five (5) or fewer calendar days and simulate in-service operations.
2.2 The primary objectives of the SROV include validation in the following areas:(i) normal flight operations, (ii) limited non-normal flight operations, (iii) routine maintenance activities, (iv) select non-routine maintenance activities, (v) airplane connectivity options both on-ground and in-flight utilizing Customer’s IT infrastructure, (vi) typical aircraft operations (e.g. servicing, cargo operations), and (vii) aircraft support products (e.g. flight data, maintenance data, parts data and ground support equipment/tooling).
2.2.1 SROV planning documentation will describe SROV conditions and activities (SROV Plan). Boeing and Customer will jointly develop the SROV Plan in accordance with the following outline and constraints, to represent in-service operation.

|  | SA-6
|  | Page 1
| BOEING PROPRIETARY |

[***]
2.2.2 Prior to the start date of the SROV, a Boeing SROV project leader (SROV Project Lead) will be the primary point of contact for communication and coordination between Customer and Boeing relating to the SROV Plan. After the SROV begins, a Boeing test director (Boeing Test Director) will direct the SROV Plan and will serve as the primary contact for Customer to discuss any matters relating to the SROV.
2.2.3 After the SROV begins, Customer will coordinate with the Boeing Test Director regarding any suggested changes to the SROV Plan or additional validation conditions, examples of which are listed below. Inclusion of such additional validation conditions will be at the discretion of the Boeing Test Director. If Boeing desires to make any changes to the SROV Plan, then Boeing will coordinate such changes with Customer’s designated representative.
a)Non-routine activities – flaps-15 landing, simulated removal and replacement of an LRU or other “one-off” or contingency scenarios related to normal operations.
b)Routine activities with intervals longer than the SROV execution duration – “A-check equivalent” maintenance activity or demonstration of new (i) ground support equipment (GSE) or (ii) maintenance procedures.
c)Airline-specific scenarios – passenger-related preparations that depend on aircraft/airlines systems or procedures to be successful.
3. Operation of the SROV Aircraft.

3.3.3 Customer will assist Boeing with any emergency arrangements or contingency arrangements in the event of incident or damage to the SROV Aircraft or other difficulties.
3.3.4 Customer will appropriately familiarize Boeing personnel with Customer's operations and procedures, at no charge to Boeing (including but not limited to Boeing flight crew and maintenance personnel).

3.4.3 Fuel and Other Goods and Services.
3.4.3.1 Customer and Boeing will work together to ensure that appropriate landing slots, gates and other operational requirements and services are arranged in advance at all airports where the SROV Aircraft will land. Where Customer's established relationships and onsite personnel and resources will enable Customer to make more advantageous arrangements, Customer will, upon Boeing request, make necessary arrangements on Boeing's behalf or will assist Boeing in making such arrangements, as appropriate.

5. Realization of Additional Objectives during SROV.
The primary objectives of the SROV are described in Paragraph 2.1 above. Other objectives are secondary, and may be pursued when, in Boeing's and Customer’s reasonable judgment, such secondary objective will not: (i) interfere with nor jeopardize the primary objectives, (ii) lengthen the SROV schedule or (iii) [***]

6. Contingencies.
6.1 SROV Aircraft Airworthiness Certification.
Boeing shall make reasonable and timely efforts to obtain an experimental airworthiness certificate or make other arrangements for airworthiness certification of the SROV Aircraft in order to conduct the SROV Plan. In the event that Boeing is not successful in obtaining the necessary airworthiness certification and cannot make alternate arrangements in support of the SROV Plan, Boeing and Customer will mutually agree to revisions to the SROV Plan to facilitate such airworthiness certification of the SROV Aircraft. If Boeing and Customer (i) cannot agree on such revisions to the SROV Plan or (ii) Boeing is unable to obtain an airworthiness certification of the SROV Aircraft, then Boeing may cancel any part or all of the SROV.
6.2 Boeing Type Certificate Flight Testing.
Boeing will make every reasonable effort to ensure the SROV Aircraft is no longer required to support 737-8 type certification during the SROV period. However, in the event that unplanned type certification testing requires use of the SROV Aircraft during the period the parties plan to conduct the SROV, Boeing may (i) cancel the SROV (ii) re-schedule the SROV and/ or (iii) adjust the scope of the SROV Plan as appropriate.

1.Additional Delivery Requirements - Import.
Customer will be the “importer of record” (as defined by the U.S. Customs and Border Protection) for all BFE imported into the United States, and as such, it has the responsibility to ensure all of Customer’s BFE shipments comply with U.S. Customs Service regulations. In the event Customer requests Boeing, in writing, to act as importer of record for Customer’s BFE, and Boeing agrees to such request, Customer is responsible for ensuring Boeing can comply with all U.S. Customs Import Regulations by making certain that, at the time of shipment, all BFE shipments comply with the requirements in the “International Shipment Routing Instructions”, including the Customs Trade Partnership Against Terrorism (C-TPAT), as set out on the Boeing website referenced below. Customer agrees to include the International Shipment Routing Instructions, including C-TPAT requirements, in each contract between Customer and BFE supplier.

3. Additional Delivery Requirements - Import
Customer will be the “importer of record” (as defined by the U.S. Customs and Border Protection) for all BFE imported into the United States, and as such, it has the responsibility to ensure all of Customer’s BFE shipments comply with U.S. Customs Service regulations. In the event Customer requests Boeing, in writing, to act as importer of record for Customer’s BFE, and Boeing agrees to such request, Customer is responsible for ensuring Boeing can comply with all U.S. Customs Import Regulations by making certain that, at the time of shipment, all BFE shipments comply with the requirements in the “International Shipment Routing Instructions”, including the Customs Trade Partnership Against Terrorism (C-TPAT), as set out on the Boeing website referenced below. Customer agrees to include the International Shipment Routing Instructions, including C-TPAT requirements, in each contract between Customer and BFE supplier.
