Subject:    Promotional Support

Reference:      Purchase Agreement No.  03776 (Purchase Agreement) between The Boeing Company (Boeing) and United Airlines, Inc. (as assignee of United Continental Holdings, Inc.) (Customer) relating to Model 737 *** aircraft (Aircraft)

This letter agreement (Letter Agreement) amends and supplements the Purchase Agreement.     This  Letter  Agreement  supersedes  and  replaces  in  its  entirety  Letter Agreement UAL-PA-03776-LA-1207646R1 dated December 13, 2013.  All terms used but not defined in this Letter Agreement shall have the same meaning as in the Purchase Agreement.

Boeing and Customer wish to enter into an agreement pursuant to which each party will contribute equally to promotional programs in support of the entry into service of the Aircraft as more specifically provided below.

1.    Definitions.

1.1    Commitment Limit shall have the meaning set forth in Article 2, below.

1.2    Covered Aircraft shall mean those Aircraft identified on Table 1, Table 1.1 and
Table 1A to the Purchase Agreement as of the date of signing of this Letter Agreement.

1.3      Performance Period shall mean the period beginning *** after the scheduled delivery  ***  of  the  first  Covered  Aircraft.    Customer  requested,  and  Boeing  agreed  to provide, *** of the Performance Period ***.

1.4     Promotional Support shall mean mutually agreed *** promotion programs, advertising campaigns or such other marketing and promotional activities as the parties may mutually agree.

1.5       Qualifying Third Party Fees shall mean fees paid by Customer to third party providers for Promotional Support provided to Customer during the Performance Period.

2.    Commitment.

As more particularly set forth in this Letter Agreement, Boeing agrees to provide Promotional Support to Customer during the Performance Period in a value not to exceed *** for the first Covered Aircraft delivered to Customer and not to exceed *** per Covered Aircraft for each  Covered  Aircraft  delivered  to  Customer  thereafter.

Customer may request payment of any or all of such Promotional Support prior to delivery of the first Covered Aircraft to Customer.

3.    Methods of Performance.

3.1      Subject to the Commitment Limit, Boeing will reimburse *** of Customer’s payments of Qualifying Third Party Fees provided that Customer provides Boeing copies of paid invoices for such Qualifying Third Party Fees no later than *** after the delivery of the first Covered Aircraft.

3.2       Notwithstanding  the  above,  at  Customer’s  request  and  subject  to  a  mutually agreed project, Boeing will provide certain Promotional Support during the Performance Period directly to Customer.  The full value of such Boeing provided Promotional Support will be accounted for as part of the Commitment Limit and will correspondingly reduce the amount of Qualifying Third Party Fees that are subject to reimbursement pursuant to Article 3.1 above. Additionally,   without   duplication   the   parties   agree   that   the   sum   of   ***   (One-Time Non-Matching Promo Support) shall be available to Customer on a one-time non-matching basis.  For the avoidance of doubt, the One-Time Non-Matching Promo Support shall be spent on promotional activity selected at Customer’s discretion and shall be made available within *** of the effective date of this Letter Agreement.

3.3       In the event Customer does not (i) utilize the full amount of the Commitment Limit within the Performance Period or (ii) submit its paid invoices for Qualifying Third Party Fees within the required time, as set forth in Article 3.1, Boeing shall have no further obligation to Customer for such unused Commitment Limit or to *** Customer for such Qualifying Third Party Fees, respectively.

4.    Project Approval.

Following the execution of this Letter Agreement, a Boeing Airline Marketing Services representative will meet with Customer’s designated representative to review and approve the extent,  selection,  scheduling,  and  ***  process  for  the  Promotional  Support  to  be  provided pursuant to this Letter Agreement.

5.    Assignment.

Except as provided in Letter Agreement No. UAL-PA-03776-LA-1208238 the rights and obligations described in this Letter Agreement are provided to Customer in consideration of Customer’s becoming the operator of the Aircraft and cannot be assigned in whole or, in part.

6.    Confidential Treatment.

Customer and Boeing understand that certain commercial and financial information contained in this Letter 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-

Subject:    Installation of Cabin Systems Equipment

Reference:    Purchase  Agreement  No. 03776  (Purchase  Agreement)  between  The  Boeing
Company (Boeing) and United Airlines, Inc. (Customer) relating to Model 737
*** 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.

Customer has requested that Boeing install in the Aircraft the In-Flight Entertainment and communications systems (collectively referred to as Cabin Systems Equipment or CSE) described  in  (i)  Attachment A1  to  this  Letter  Agreement  for  the  737-***  Aircraft  and (ii) Attachment A2 to this Letter Agreement for the 737-*** Aircraft (Attachments A1 and A2 collectively referred to herein as Attachment A). CSE is BFE that Boeing purchases for Customer and that is identified in the Detail Specification for the applicable Aircraft.

1.    Customer Responsibilities.

1.1       For 737-*** Aircraft, Customer has already selected CSE suppliers (Supplier(s)) system configuration and Options identified in Attachment A1 to this Letter.  For the 737-*** Aircraft, Customer will select Suppliers and system configuration from among those identified in the Option(s) listed in Attachment A2 to this Letter Agreement (Attachment A1 and Attachment A2 referred to collectively as Attachment A), ***; or as otherwise available in the then current Standard Selections Catalog and formally offered by Boeing.

1.2       Customer  will  enter  into  initial  agreements  with  their  selected  Suppliers,  or otherwise cause the selected Suppliers, to actively participate with Customer and Boeing in meetings, including but not limited to the Initial Technical Coordination Meeting (ITCM), to ensure that Supplier's functional system specifications meet Customer's and Boeing's respective requirements. Such functional system specifications define functionality to which Boeing will test prior to delivery but are not a guarantee of functionality at delivery.

	BOEING / UNITED AIRLINES, INC. PROPRIETARY

1.3    Customer will enter into final agreements with the selected Suppliers that will:

1.3.1  include the actual statement of work as defined at the ITCM. Final agreements  will  also  include  price,  warranty,  training,  product  support  following  Aircraft delivery (including spares support), and any other special business arrangements required by Customer;

1.3.2   require Supplier to assist the seat suppliers in the preparation of seat assembly functional test plans and procedures and coordinate integration testing; and

1.3.3    require   Supplier   to   comply   with   Boeing’s   type   design   and   type certification data development and protection requirements where the Supplier has type design/certification responsibility. The requirements will require Suppliers to (i) maintain type design/certificate data for *** such type certificate for all type design and (ii) entitle Boeing to access, review, and receive such type design/certification data. These requirements will be provided to Customer upon request.

2.    Boeing Responsibilities.

2.1    Boeing will:

2.1.1    perform the Project Manager functions stated in Attachment B;

2.1.2    provide Aircraft interface requirements to Suppliers;

2.1.3   assist Suppliers in the development of CSE system specifications and approve such specifications;

2.1.4    release purchase orders, including on-dock dates to Supplier on behalf of
Customer, and manage such purchase orders;

2.1.5    coordinate the resolution of technical issues with Suppliers;

2.1.6    ensure that at the time of Aircraft delivery the CSE configuration meets the requirements of the Option(s) contained in Attachment A to this Letter Agreement as such Attachment A may be amended from time to time; and

2.1.7    obtain FAA certification of the Aircraft with the conforming CSE installed therein.

3.    Software.

CSE systems may contain software of the following two types:

3.1    Certification Software. The software required to functionally test, operate and certify the CSE systems on the Aircraft is the Certification Software and is part of the CSE.

3.2    Customer's Software. The software which is defined by the Customer to support specified features and appearance is Customer's Software and is not part of the CSE.

3.2.1  Customer is solely responsible for specifying Customer's Software functional and performance requirements and ensuring that Customer's Software meets such requirements.  Customer and Customer's Software supplier will have total responsibility for the writing,  certification,  modification,  revision,  or  correction  of  any  of  Customer's  Software. Boeing will not perform the functions and obligations described in paragraph 1.2 above, or the Project Manager's functions described in Attachment B, for Customer's Software.

3.2.2    The omission of any Customer's Software or the lack of any functionality of Customer's Software will not be a valid condition for Customer's rejection of the Aircraft at the time of Aircraft delivery unless such omission or lack of functionality is due to a breach by Boeing of its obligations under this Purchase Agreement.

3.2.3  Boeing has no obligation to approve any documentation to support Customer's Software certification. Boeing will only review and operate Customer's Software if in Boeing's reasonable opinion such review and operation is necessary to certify the CSE on the Aircraft.

3.2.4    Boeing  will  not  be  responsible  for  obtaining  FAA  certification  for
Customer's Software.

4.    Changes.

Any changes to CSE may only be made by and between Boeing and the Supplier. Customer requested changes to the CSE specification after execution of this Letter Agreement will be made in writing directly to Boeing for approval and for coordination by Boeing with the Supplier. Any such change to the configuration of the Aircraft will be subject to *** through Boeing’s master change or other process for amendment of the Purchase Agreement. Any Supplier price increase or decrease resulting from such change will be negotiated between Customer and Supplier.

4.1       Boeing and Customer recognize that the developmental nature of the CSE may require changes to the CSE or the Aircraft in order to ensure (i) compatibility of the CSE with the Aircraft and all other Aircraft systems, and (ii) FAA certification of the Aircraft with the CSE installed therein.  In such event Boeing will notify Customer and recommend to Customer

	BOEING / UNITED AIRLINES, INC. PROPRIETARY

the most practical means for incorporating any such change.  If *** after such notification Customer and Boeing cannot mutually agree on the incorporation of any such change or alternate course of action, the remedies available to Boeing in Paragraph 6 will apply.

5.         Supplier Defaults.

Boeing will notify Customer in a timely manner in the event of a default by a Supplier under the Supplier's purchase order with Boeing. *** of Customer's receipt of such notification, Boeing and Customer will agree on an alternate Supplier or other course of action. If Boeing and Customer are unable to agree on an alternate Supplier or course of action within such time, the remedies available to Boeing in paragraph 6 will apply.

6.         Exhibits B and C to the AGTA.

CSE is deemed to be BFE for the purposes of Exhibit B, Customer Support Document, and Exhibit C, the Product Assurance Document, of the AGTA.

7.    Boeing’s Remedies.

If Customer does not perform its obligations as provided in this Letter Agreement or if a Supplier fails (for any reason other than a default by Boeing under the purchase order terms or this Letter Agreement) to deliver conforming CSE per the schedule set forth in the purchase order, then, in addition to any other remedies which Boeing may have by contract or under law, Boeing may:

7.1       revise the scheduled delivery month of the Aircraft to accommodate the delay in delivery of the conforming CSE and base the calculation of the *** Adjustment on such revised delivery month;

7.2       deliver the Aircraft without part or all of the CSE installed, or with part or all of the CSE inoperative; and/or

7.3       increase the Aircraft Price by the amount of Boeing's additional costs attributable to such noncompliance, including but not limited to, *** associated with *** by Boeing, any *** due to a Supplier’s failure to perform in accordance with CSE program milestones as established by Boeing and agreed to by the Supplier and particularly with respect to *** of such CSE.

8.    Price and Payment.

8.1       ***. An estimated price for the CSE purchased by Boeing will be included in the Aircraft *** to establish the *** for each Aircraft.  The estimated price for the Boeing purchased CSE installed on each Aircraft is identified in Table 1 of the Purchase Agreement.

8.2      Aircraft Price.  The Aircraft Price will include the actual CSE prices and any associated costs, including but not limited to transportation and import or export fees, charged to Boeing by Suppliers.

9.    Customer's Indemnification of Boeing.

THE  PROVISIONS  OF  AGTA,  EXHIBIT A,  BUYER  FURNISHED  EQUIPMENT PROVISIONS DOCUMENT, “INDEMNIFICATION OF BOEING” WILL APPLY TO CSE.

10.    Title and Risk of Loss.

Title to CSE will remain with Boeing from the time that Boeing receives title to the CSE until the Aircraft title is transferred to Customer. Risk of loss will remain with the entity that is in possession of the CSE prior to Aircraft delivery.

If the foregoing correctly sets forth your understanding of our agreement with respect to the matters contained herein, please indicate your acceptance and approval below.
