(Customer) relating to Model 787 aircraft (Aircraft) This letter agreement (Letter Agreement) amends and supplements the Purchase Agreement. All terms used but not defined in this Letter Agreement will 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 described in Attachment A to this Letter Agreement (collectively referred to as Cabin Systems Equipment or CSE). CSE is BFE that Boeing purchases for Customer and that is identified as CSE in the Detail Specification for the Aircraft. The complexity of the CSE requires special attention and additional resources during the development, integration, and certification of the CSE and manufacture of the Aircraft to achieve proper operation of the CSE at the time of delivery of the Aircraft. To assist Customer, Boeing will perform the functions of project manager (Project Manager) as set forth in Attachment B. 1. Responsibilities. 1.1 Customer will: 1.1.1 provide Customer’s CSE system requirements to Boeing; 1.1.2 select the CSE suppliers (Supplier(s)) and system configuration options in accordance with Letter Agreement UAL-PA-03860-LA- 1301373 (mistakenly referred to as Letter Agreement UAL-PA-03860-LA-01373 in the letter itself), entitled “787-10 Open Configuration and Other Matters”; or options from among those identified in Attachment A to this Letter Agreement; or options as otherwise available in the then current Standard Selections Catalog and formally offered by Boeing (Options); UAL-PA-03860-LA-1500059 SA-4 Cabin Systems Equipment LA Page 1 BOEING / UNITED AIRLINES, INC. PROPRIETARY

1.1.3 promptly after selecting the Options, participate with Boeing in meetings with Suppliers 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; 1.1.4 select Supplier part numbers; 1.1.5 negotiate and obtain agreements on product assurance, product support following Aircraft delivery (including spares support), and any other special business arrangements directly with Suppliers; 1.1.6 provide to Boeing pricing information for Customer selected CSE part numbers by a mutually agreeable date; 1.1.7 negotiate and obtain agreements with any applicable service providers; 1.1.8 include in Customer’s contract with any seat supplier a condition causing such seat supplier to enter a bonded stores agreement with Boeing. This bonded stores agreement will set forth the terms concerning the use, handling, storage, and risk of loss of CSE during the time such equipment is under the seat supplier’s control; 1.1.9 cause Suppliers to: 1.1.9.1 assist the seat suppliers in the preparation of seat assembly functional test plans; 1.1.9.2 coordinate integration testing, and provide seat assembly functional test procedures for seat electronic parts to seat suppliers and Boeing, as determined by Boeing; and 1.1.9.3 comply with Boeing’s 787 procurement processes (e.g. for transmission of technical data, transmission of purchase orders, and processing of non-conformances) (787 Procurement Processes). 787 Procurement Processes will be provided to Customer and may be updated from time to time; and 1.1.9.4 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 and included in any applicable contracts between Customer and Supplier. UAL-PA-03860-LA-1500059 Cabin Systems Equipment SA-4 LA Page 2 BOEING / UNITED AIRLINES, INC. PROPRIETARY 1.2 Boeing will: 1.2.1 perform the Project Manager functions stated in Attachment B; 1.2.2 provide Aircraft interface requirements to Suppliers; 1.2.3 assist Suppliers in the development of CSE system specifications and approve such specifications; 1.2.4 release purchase orders, including on-dock dates to Supplier on behalf of Customer, and manage such purchase orders; 1.2.5 coordinate the resolution of technical issues with Suppliers; 1.2.6 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 1.2.7 obtain FAA certification of the Aircraft with the conforming CSE installed therein. 2. Software. CSE systems may contain software of the following two types: 2.1 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. 2.2 Customer’s Software. The software which is defined by the Customer to support customized features and appearance is Customer’s Software and is not part of the CSE. 2.2.1 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. 2.2.2 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. UAL-PA-03860-LA-1500059 Cabin Systems Equipment SA-4 LA Page 3 BOEING / UNITED AIRLINES, INC. PROPRIETARY 2.2.3 Boeing has no obligation to approve any documentation to support Customer’s Software certification. Boeing will review and operate Customer’s Software only if in Boeing’s reasonable opinion such review and operation is necessary to certify the CSE on the Aircraft. 2.2.4 Boeing will not be responsible for obtaining FAA certification for Customer’s Software. 3. Changes. 3.1 Any Customer request for changes to the CSE specification after Customer acceptance of the Options 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. 3.2 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 the most practical means for incorporating any such change. If within fifteen (15) days 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. 4. 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. Within fifteen (15) days 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. 5. 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. 6. 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 UAL-PA-03860-LA-1500059 Cabin Systems Equipment SA-4 LA Page 4 BOEING / UNITED AIRLINES, INC. PROPRIETARY 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: 6.1 revise the scheduled delivery month of the Aircraft to accommodate the delay in delivery of the conforming CSE and base the calculation of the Escalation Adjustment on such revised delivery month; 6.2 deliver the Aircraft without part or all of the CSE installed, or with part or all of the CSE inoperative; and/or 6.3 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. 7. Advance Payments. 7.1 Estimated Price for the CSE. An estimated price for the CSE purchased by Boeing will be included in the Aircraft Advance Payment Base Price to establish the advance payments for each Aircraft.
