|--------|-------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | 3.2.1 | Installation Delays.  Following a Module Exchange Shop Visit, if the Northwest experiences installation delays due to nuisance snags such as oil leaks, from areas serviced during the agreed to work scope, which may be corrected during the installation process, the Northwest shall correct and document the snag and will notify the VENDOR ofthe concern. The replacement of dried out o-rings, re-torqueing of lines and hoses, and minor adjustments are considered normal engine installation activities. Any corrective action performed by the Northwest beyond this scope shall be invoiced to VENDOR, and stated in man-hours consumed to perform the corrective action. The VENDOR shall issue a credit in the amount equal to the man-hours consumed multiplied by the labor cost per hour amount stated in the agreement in Attachment C, Section 3.1 “Labor FixedPrice Per Category” under the heading of “Labor For Extra Work”. |

|--------|-------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | 3.3.2 | On Wing First Test Pass Rate shall be calculated as a rolling 50 engine average, as follows |
|--------|-------|---------------------------------------------------------------------------------------------|

|   | 3.3.4 | If the On Wing First Test Pass Rate falls below the guarantee in Section 3.3.1 of this Attachment, VENDOR shall implement a corrective action plan, at no additional cost to Northwest, to eliminate the root causes of the test failures. Such corrective action plan shall include a test cell run and other tasks as may be determined by VENDOR prior to delivery, which will continue until the performance metric reachesthe On Wing First Test Pass Rate guarantee or a shorter interval of time as may be mutually agreed to between the Operator and VENDOR, based on the type of corrective actions taken and nature of the root cause test failures. This corrective action plan will commence beginning with the next scheduled Engine removed for Module Exchange Shop Visit. The VENDOR will communicate the plan, ongoing status, and resolution to Northwest. |
|--------|-------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | 3.3.5 | This guarantee will not apply if the test failure is caused by an unserviceable LRU received on the Engine, which was not repaired as part of the module exchange work scope, or if Northwest has performed any maintenance on the Engine after delivery from VENDOR, and if the failure is attributable to the work performed by Northwest. |
|--------|-------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 4.0 | WARRANTIES |
|-----|------------|

|   | 4.1 | Warranty. VENDOR warrants that Services performed under this Agreement will, at time of Redelivery, be free from defects in workmanship for a period of [***] from Redelivery of Engine or LRU, or [***] hours of operation of the Engine or LRU, whichever shall first occur.

|   | 4.2 | Resultant Damage. During the warranty period specified in Paragraph 3.1 above, VENDOR agrees that in the event any Engine or LRU suffers Resultant Damage, VENDOR shall restore the damaged Engine or LRU to serviceable condition equivalent to that immediately preceding the damage at no cost to Northwest unless the Resultant Damage is due to a defect inNorthwest supplied material and/or an PAH part. The warranty period on any such repaired or replaced Engine or LRU shall be the unexpired portion of the warranty on the initially repaired item.   In no event shall VENDOR be liable for indirect or consequential damages of any kind or nature and the obligation to repair the resulting Engine or LRU damage is the sole and exclusive remedy of Northwest in the event of defective workmanship. |
