If such calibration verifies that the exhaust gas temperature of the Engine is not in excess of the Certified Limit or it is established that any excess is due to causes which are excluded by the General Conditions in Section III, then the cost of such test cell calibration and associated transportation will be borne by AWA. E. Restoration of Removed Engine If (i) calibration under Section II, Paragraph D verifies that the exhaust gas temperature of the Engine is in excess of the Certified Limit, and (ii) such excess was the sole reason for removing such Engine from the Aircraft, IAE shall: a) bear the cost of such test cell calibration; b) define the extent of work which will need to be carried out on the Eligible Engine, its Modules and its Parts to restore its performance such that its maximum stabilized exhaust gas temperature should not again exceed the Certified Limit prior to expiration of the Period of Guarantee; and, c) either: c.1 Issue a credit note to AWA in an amount equal to one hundred percent (100%) Parts Credit Allowance and Labor Allowance for work carried out by AWA calculated in accordance with the V2500 Engine and Parts Service Policy; or c.2 make no charge for such work carried out by IAE. III DEFINITIONS AND GENERAL CONDITIONS All of the Definitions and General Conditions of the V2500 Engine and Parts Service Policy shall apply to this Guarantee. Engines excluded by the General Conditions of the Policy shall be excluded from this Guarantee. IV SPECIFIC CONDITIONS A. The Guaranteed Rate is predicated on the use by AWA of: 1. An average flight cycle of no less than 1.9hours; 2. Thrust levels which are derated an average of 10 percent for Takeoff and Climb relative to full Takeoff and Climb ratings; 3. An average Aircraft utilization equal to or less than 3,400 flight hours per year; and 4. An Aircraft and Engine delivery schedule in respect of 24 firm Aircraft and 6 spare Engines as described in the Proposal or Contract to which this Guarantee is attached. B. IAE reserves the right to make appropriate adjustments to the Guaranteed Rate if there is, during the Period of Guarantee, a variation from the conditions upon which 59 the Guaranteed Rate is predicated or a discontinuation of ownership by AWA of any Engine or any V2500 powered Aircraft subsequent to delivery to AWA. V EXCLUSION OF BENEFITS The intent of this Guarantee is to provide specified benefits to AWA as a result of the failure of Eligible Engines to achieve the performance level stipulated in the Guarantee. It is not the intent, however, to duplicate benefits provided to AWA under any other applicable guarantee, sales warranty, service policy, or any special benefit of any kind as a result of the same failure. Therefore, the terms and conditions of this Guarantee notwithstanding, if the terms of this Guarantee should make duplicate benefits available to AWA from IAE or any third-party, AWA may elect to receive the benefits under this Guarantee or under any of the other benefits described above, but not both.
