 2.1 If the *** substantially revises the methodology used for the
determination of the values to be used to determine the *** and *** values (in contrast to benchmark adjustments or other corrections of previously released values), or for any reason has not released values needed to determine the applicable
Airframe Price Adjustment, the parties will, prior to the delivery of any such Aircraft, select a substitute from other *** or ***. Such substitute will result in the same adjustment, insofar as possible, as would have been calculated utilizing the
original values adjusted for fluctuation during the applicable time period. However, if within *** months after delivery of the Aircraft, the *** should resume releasing values for the months needed to determine the Airframe Price Adjustment,
***will be used *** or ***in the ***for the *** that ***at the ***of *** of ***. 
 2.2 Notwithstanding Article 2.1 above,

	Subject:	  	Open Matters
		
	Reference:	  	Purchase Agreement No. 03776 (Purchase Agreement) between The Boeing Company (Boeing) and United Continental Holdings, Inc. (Customer) relating to
Model 737-9 aircraft (Aircraft)

 This letter agreement (Letter Agreement) amends and supplements the Purchase Agreement. All terms
used but not defined in this Letter Agreement shall have the same meaning as in the Purchase Agreement. 
 Given the long period
of time between Purchase Agreement signing and delivery of the first Aircraft and the continued development of the 737 MAX program, certain elements have not yet been defined. In consideration, Boeing and Customer agree to work together as the 737
MAX program develops as follows: 
 1. Aircraft Delivery Schedule. 

1.1 The scheduled delivery position of the Aircraft, as of the date of this Letter Agreement is listed in Table 1 of the Purchase
Agreement and provides the delivery schedule in *** delivery windows consisting of a nominal delivery month (Nominal Delivery Month) ***. No later than *** prior to Nominal Delivery Month of Customer’s first Aircraft in each calendar
year, Boeing will provide written notice with a *** scheduled delivery month for each Aircraft with a Nominal Delivery Month in such calendar year. 
 1.2 Customer and Boeing will consult on a frequent basis to keep each other informed as to Customer’s fleet plans and Boeing’s production plans in order to meet the requirements of both parties.
Based on such reviews and discussions, Boeing will use commercially reasonable efforts to meet Customer’s fleet needs when providing the notices required by Article 1.1. Such notices provided by Boeing will constitute an amendment to Table 1 of
the Purchase Agreement. The amended Table 1 shall be the scheduled delivery positions for the purposes of applying all provisions of the Purchase Agreements, including without limitation the BFE on-dock dates, and *** the *** for the Aircraft.

 2. Aircraft Configuration.

	Open Matters	 	Page 1

 

 
  
 2.1 The initial
configuration of Customer’s Model Aircraft has been defined by Boeing 737-9 Airplane Description Document No. *** dated *** as described in Article 1 and Exhibit A of the Purchase Agreement (Initial Configuration). Final
configuration of the Aircraft (Final Configuration) will be completed using the then-current Boeing configuration documentation in accordance with the following schedule: 

2.1.1 No later than *** prior to the first Aircraft’s scheduled delivery, Boeing and Customer will discuss potential optional
features. 
 2.1.2 Within *** after that meeting, Boeing will provide Customer with a proposal for those optional features that
can be incorporated into the Aircraft during production. 
 2.1.3 Customer will then have *** to accept or reject the optional
features. 
 2.1.4 Within *** following Final Configuration, Boeing and Customer will execute a written amendment to the Purchase
Agreement which will reflect the following: 
 2.1.4.1 Changes applicable to the basic Model 737-9 aircraft which are developed
by Boeing between the date of signing of the Purchase Agreement and date of Final Configuration. 
 2.1.4.2 Incorporation into
Exhibit A of the Purchase Agreement, by written amendment, those optional features which have been agreed to by Customer and Boeing (Customer Configuration Changes); 

2.1.4.3 Revisions to the Supplemental Exhibit BFE1 to reflect the selection dates and on-dock dates of BFE; 

2.1.4.4 Changes to the Optional Features Prices, and Aircraft Basic Price to adjust for the difference, if any, between the prices
estimated in Table 1 of the Purchase Agreement for optional features reflected in the Aircraft Basic Price and the actual prices of the optional features reflected in the Customer Configuration Changes. Such changes will not result in a *** to
the *** provided in Table 1. 
 3. Customer Support Variables. 
 3.1 The initial customer support package contained in Supplemental Exhibit CS1 to the Purchase Agreement is predicated upon the 737NG customer support package. Boeing intends to further refine the post
delivery support package for the 737 MAX and will provide this revised package to Customer no later than *** prior to the first month of the scheduled delivery quarter of the first Aircraft. The provision of such revised Supplemental Exhibit CS1
will constitute an amendment to the Purchase Agreement and will provide the Customer in aggregate an overall Boeing post delivery support package that is equivalent to, or better than, the Supplemental Exhibit CS1 included in the Purchase Agreement
as of the date of this Letter Agreement.

 3.2 Additionally, Boeing
will engage in discussions with Customer in conjunction with the providing of the updated Supplemental Exhibit CS1 to offer to Customer additional uniquely tailored post delivery support services beyond the scope of the Supplemental Exhibit CS1 that
will further enhance the maintainability and operational efficiency of the Aircraft. 
 4. *** Guarantees. 

4.1 At the time of signing of the Purchase Agreement, the performance specification for the Aircraft is not fully defined and as such,
Boeing will provide Customer complete *** guarantees applicable to the Aircraft no later than ***. Such *** guarantees will reflect the commitment set below and amend and supplement the Purchase Agreement. 

4.1.1 *** – *** to the specifically defined *** nautical mile *** established in *** and ***, the Aircraft *** in *** for the defined
*** nautical mile Customer mission will be ***% *** in *** for ***. 
 4.1.2 *** – The Aircraft at its *** will have the ***

 4.1.3 *** – The Aircraft will be capable of flying all routes *** to *** and *** to *** the 737-*** aircraft utilizing *** engines flies with *** on those respective routes. 

4.2 If i) the complete *** guarantees (excluding ***) provided to Customer pursuant to Article 4.1 of this Letter Agreement *** guarantee
*** as described in Article 4.1.2 and Article 4.1.3 of this Letter Agreement or ii) the actual Aircraft *** (excluding ***) *** guarantees provided to Customer pursuant to Article 4.1 of this Letter Agreement, and such *** the *** to Customer or the
*** to Customer, then *** of *** and *** the Purchase Agreement and ***. In addition, *** agrees that, if *** is *** to ***a ***to***the***within a *** and does not *** within a ***that it will ***such a ***, then***will have the ***any such ***and,

 5. Other Letter Agreements.

 Boeing and Customer acknowledge that as they work together to develop the 737-9 program and as Boeing refines the
definition of the Aircraft and associated production processes, there may be a need to execute or amend additional letter agreements addressing one or more of the following:

accomplish phased provisioning of Spare Parts and Standards for the Aircraft in accordance with the Provisioning Products Guide. If the lead time from execution of the Purchase Agreement until
delivery of the first Aircraft is less than twelve (12) months, the initial provisioning meeting will be established as soon as reasonably possible after execution of the Purchase Agreement. 

2.3 Provisioning Data. During the initial provisioning meeting Customer will provide to Boeing the operational parameter
information described in Chapter 6 of the Provisioning Products Guide. After review and acceptance by Boeing of such Customer information, Boeing will prepare the Provisioning Data. Such Provisioning Data will be furnished to Customer on or

of Spare Parts and Standards for the Aircraft. Boeing will furnish to Customer revisions to the Provisioning Data periodically (or upon Customer request) until approximately ninety (90) days following delivery of the last Aircraft or until the
delivery configuration of each of the Aircraft is reflected in the Provisioning Data, whichever is later. Upon mutual agreement during the initial provisioning meeting, Boeing will make its representative available to support Customer’s Spare
Provisioning activities related to major milestone events, starting with the initial implementation through the first heavy maintenance check for the first Aircraft. This will be accomplished by a combination of on site support at the Customer
and/or dedicated focal at Boeing base upon the requirements and statement of work associated with the activity. 
 2.4 Buyer

 3.2 Prices of Initial Provisioning Spare Parts.

 3.2.1 Boeing Spare Parts. The Provisioning Data will set forth the prices for those Provisioning Items other than items
listed in Article 3.3, below, that are Boeing Spare Parts, and such prices will be firm and remain in effect for a minimum of ninety (90) days from the date the price is first quoted to Customer in the Provisioning Data. Boeing Spare Parts

Items or for any items ordered for initial provisioning of GSE, special tools manufactured by suppliers, or engine spare parts will be *** percent (***%) of the supplier’s list price for such items. If a product support and assurance
agreement (PSAA) with a supplier is effective, then such supplier’s Supplier Spare Parts pricing will escalate pursuant to the provisions of such PSAA.

accordance with schedules established during the initial provisioning meeting. For parts that are deemed Boeing Spare Parts, such pricing will remain in effect for a minimum of *** days from the date the price is first quoted to Customer.

 4. Delivery. 

For Spare Parts and Standards ordered by Customer in accordance with Article 3 of this Letter Agreement, Boeing will, insofar as
reasonably possible, deliver to Customer such Spare Parts and Standards on dates reasonably calculated to conform to Customer’s anticipated needs in view of the scheduled deliveries of the Aircraft. Customer and Boeing will agree upon the date
to begin delivery of the provisioning Spare Parts and Standards ordered in accordance with this Letter Agreement. Where appropriate, Boeing will arrange for shipment of such Spare Parts and Standards which are manufactured by suppliers directly to
Customer from the applicable supplier’s facility. The routing and method of shipment for initial deliveries and all subsequent deliveries of such Spare Parts and Standards will be as established at the initial provisioning meeting and
thereafter by mutual agreement.

Subject:         Assignment Matters 
 Reference:     Purchase Agreement No. PA-03776 (Purchase Agreement) between The Boeing Company (Boeing) and United
                      Continental Holdings, Inc. (Customer) relating to Model 737-9 aircraft (Aircraft) 

This letter agreement (Letter Agreement) amends and supplements the Purchase Agreement. All terms used but not defined in this
Letter Agreement shall have the same meaning as in the Purchase Agreement. 
 Notwithstanding any statement to the contrary in
the Purchase Agreement or letter agreements to the Purchase Agreement, Boeing acknowledges that Customer will not become the operator of the Aircraft (and is not an airline), and that Customer intends to assign its rights and obligations under the
Purchase Agreement with respect to all or a portion of the Aircraft to one or both of Customer’s controlled subsidiaries United Air Lines, Inc. or Continental Airlines, Inc. Except for the fact that Customer will not be the operator of the
Aircraft (and is not an airline), Boeing agrees that Customer will remain entitled to and subject to all of the rights and obligations provided under the Purchase Agreement, subject to Article 1 of this Letter Agreement. 

1. Assignment of Customer’s Interest. 
 Boeing hereby consents to Customer’s assignment of Customer’s rights and interest under the Purchase Agreement to: 1) Customer’s controlled subsidiary United Air Lines, Inc. (United Air
Lines), 2) Customer’s controlled subsidiary Continental Airlines, Inc. (Continental Airlines), or 3) the successor entity resulting from the merger or consolidation of United Air Lines, Continental Airlines, and/or Customer (UAL
Entity), in each case subject to the following terms and conditions: 
 1.1 Customer must notify Boeing of its intent to
exercise its right to assign Aircraft in writing no less than *** days prior to the first day of the scheduled delivery month of the Aircraft to be assigned; 
 1.2 Boeing shall not be subject to any additional liability as a result of the assignment which Boeing would not otherwise be subject to under the Purchase Agreement; 

1.3 Customer’s assignment will include all of its rights and obligations under the Purchase Agreement with respect to the Aircraft
being assigned, and Customer’s

assignee will assume all of Customer’s right and obligations under the Purchase Agreement with respect to the Aircraft being assigned. Upon Customer’s assignment of all of its rights
and obligations under the Purchase Agreement with respect to the Aircraft being assigned to Customer’s assignee, Customer *** under the Purchase Agreement *** Boeing with respect to the Aircraft being assigned. In the event of an assignment of
all of Customer’s rights and obligations under the Purchase Agreement to Customer’s assignee, Customer *** under the Purchase Agreement *** Boeing. 
 1.4 If Customer’s assignees are either United Air Lines or Continental Airlines, then United Air Lines or Continental Airlines remain as controlled subsidiaries of Customer respectively at the time
of assignment. 
 1.5 The assignment shall not modify in any respect the continued rights of Boeing under the Purchase
Agreement, or require Boeing to divest itself of title to or possession of the Aircraft, or any other things, until delivery thereof and full payment is provided to Boeing. 
 2. Assignment. 
 This Letter Agreement is provided as an accommodation to
Customer in consideration of its relationship with Boeing, and can only be assigned pursuant to Article 9 of the AGTA, as amended. 
 3.
Confidential Treatment.

Agreement are considered by Boeing and Customer as confidential and are subject to the terms and conditions set forth in Letter Agreement No. UAL-PA-03776-LA-1208234.
