	Subject:		Installation of Cabin Systems Equipment
		
	Reference:		Purchase Agreement No. PA-03860 (Purchase Agreement) between The Boeing Company (Boeing) and United Airlines, Inc. (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.

 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.

	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

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. The estimated price for the Boeing purchased CSE installed on each Aircraft is identified in Table 1 of the
Purchase Agreement. 
 7.2 Aircraft Price. The Aircraft Price will include the actual CSE prices and any associated transportation
costs charged Boeing by Suppliers or otherwise incurred by Boeing. 
  

	8.	Customer’s Indemnification of Boeing. 

 Customer will indemnify and hold harmless
Boeing from and against all claims and liabilities, including costs and expenses (including attorneys’ fees) incident thereto or incident to successfully establishing the right to indemnification, for injury to or death of any person or
persons, including employees of Customer but not employees of Boeing, or for loss of or damage to any property, including Aircraft, arising out of or in any way connected with any nonconformance or defect in any CSE, and whether or not arising in
tort or occasioned in whole or in part by the negligence of Boeing. This indemnity will not apply with respect to any nonconformance or defect caused solely by Boeing’s installation of the CSE. 

 

	9.	Title and Risk of Loss. 

 Title of CSE will remain with Boeing 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.
