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 *** after delivery of the Aircraft, the *** should resume releasing values for the months needed to determine the ***; such values will be used to determine any *** in the *** for the Engine from that determined at the time of delivery of the Aircraft.

A. Certain third party, commercial off-the-shelf software products are available to perform various functions required in the Aircraft (COTS Software).

B. The industry practice with respect to COTS Software is to permit manufacturers to install the software in products for sale to customers. The manufacturer is required to pass to the customer an End User License Agreement (XXXX), which covers the right to use the COTS Software. The EULAs also require each user of the product to further license the software and pass the XXXX to any user to whom he transfers the product.

C. Because of the described industry practice with respect to COTS Software, Boeing does not acquire title to COTS Software and cannot pass title to COTS Software at the time of delivery of the Aircraft.

D. Therefore, the parties desire to amend certain provisions of the Purchase Agreement to properly reflect the respective rights and obligations of the parties with respect to the COTS Software included in the Aircraft.

Introduction

Prior to title transfer of the Aircraft to Customer, Boeing baseline production software will be installed in the Aircraft.

Operational software, as set out in Article 1 and Article 2 below, will not be installed temporarily or permanently on an Aircraft prior to the transfer by Boeing of title to that Aircraft to Customer or a party designated by Customer.

1. Boeing-Provided Operational Software and Data.

Pursuant to the Purchase Agreement and applicable 787 software license order(s), immediately following title transfer of the Aircraft to Customer, Boeing will, upon Customer’s request, load Boeing-provided operational software and data onto onboard loadable hardware that enable the Aircraft to operate certain e-enabled features as described in the Purchase Agreement and applicable 787 software license order(s).

If Customer provides Customer-developed software applications or has licensed additional software or databases from *** and/or other third party supplier for installation onto an onboard loadable system, at Customer’s request, Boeing will also provide a courtesy load of such operational software immediately following title transfer of the Aircraft. If Customer fails to provide such operational software in accordance with Boeing’s instructions, Boeing will not load this software.

2.3 IFE Customer Software. IFE Customer Software shall mean any software which is obtained by the Customer from a source other than Boeing for installation in the IFE system.

The time required for the IFE supplier to complete the loading of the IFE Customer Software is estimated to be approximately *** hours. If Customer fails to make appropriate arrangements with its IFE supplier in accordance with Boeing instructions, the Aircraft will be solely configured with Boeing’s baseline production software for the Boeing catalogue selected IFE configuration. Boeing’s FAA approved Repair Station will *** to Customer or its IFE supplier to revise the IFE system hardware or IFE Customer Software while the Aircraft is on Boeing property prior to delivery flyaway, even if an FAA approved service bulletin is available for such revision.

3. Additional Terms and Conditions.

3.1 With respect to Customer-provided operational software and data referenced in Article 2.1 and 2.2, above, Customer shall grant, and/or shall obtain from the suppliers, a *** license for Boeing to copy and load such software on the Aircraft. Boeing will retain a copy of such software/data for loading on future Aircraft deliveries; however, Boeing expects Customer to provide updated operational software applications and databases for each Aircraft delivery.

5.4

The takeoff portion of the mission guarantees are based on hard surface, level and dry runways with no wind or obstacles, no clearway or stopway, *** mph tires, with anti-skid operative. The takeoff performance is based on an alternate forward center of gravity limit of *** percent of the mean aerodynamic chord. The takeoff performance is based on engine power extraction for normal operation of the air conditioning with thermal anti-icing turned off and ***. Unbalanced field length calculations and the improved climb performance procedure will be used for takeoff as required.

The all-engine altitude capability guarantees, and the climb, cruise and descent portions of the mission guarantees are based on an Aircraft center of gravity location, as determined by Boeing, not to be aft of *** percent of the mean aerodynamic chord.

5.8

Performance, where applicable, is based on a fuel Lower Heating Value (LHV) of *** BTU per pound and a fuel density of *** pounds per U.S. gallon.

5.9

Cumulative Noise Certification Margin to the Chapter 4 / Stage 4 rule shall be defined as ***dB less than the sum of the differences between the three certification values (flyover with cutback, peak lateral, and approach) of the Aircraft with respect to the three noise limits defined in ICAO Annex 16, Volume 1, Chapter 3 and 14 CFR Part 36 Stage 3.
