If the next succeeding decimal place is five (5) or more, the preceding decimal figure shall be raised to the next higher figure. The final factor shall be rounded to the nearest thousandth (3 decimals). 23 5. GENERAL PROVISIONS 5.1 The Revised Reference Price at delivery of the Incremental Aircraft shall be the final price and will not be subject to further adjustments in the indexes. 5.2 If no final index value is available for any of the applicable months, the published preliminary figures will be the basis on which the Revised Reference Price will be computed. 5.3 If the US Department of Labor substantially revises the methodology of calculation of the indexes referred to in this Appendix 2 or discontinues any of these indexes, the Seller shall, in agreement with CFM International, apply a substitute for the revised or discontinued index, such substitute index to lead in application to the same adjustment result, insofar as possible, as would have been achieved by continuing the use of the original index as it may have fluctuated had it not been revised or discontinued. Appropriate revision of the formula shall be made to accomplish this result. 5.4 Should the above escalation provisions become null and void by action of the US Government, the Reference Price shall be adjusted to reflect increases in the cost of labor, material and fuel which have occurred from the period represented by the applicable Reference Price Indexes to the sixth month prior to the scheduled delivery of the Incremental Aircraft. 5.5 The Revised Reference Price at delivery of the Incremental Aircraft in no event shall be less than the Reference Price defined in Paragraph 1 of this Appendix 2. ILFC-A321 Amdt. 6-24 24 APPENDIX 3 INTERNATIONAL AERO ENGINES PRICE REVISION FORMULA 1. REFERENCE PRICE The Reference Price of a set of two (2) International Aero Engines V2530-A5 Propulsion Systems, as applicable, is as quoted in Paragraph 3 of the Amendment. This Reference Price is subject to adjustment for changes in economic conditions as measured by data obtained from the US Department of Labor, Bureau of Labor Statistics, and in accordance with the provisions of Paragraphs 4 and 5 of this Appendix 3. 2. REFERENCE PERIOD The above Reference Prices have been established in accordance with the economic conditions prevailing in March 1988 (or July 1988 theoretical delivery conditions) as defined, according to International Aero Engines, by the HEb, MMPb and EPb index values indicated in Paragraph 4 of this Appendix 3. 3. INDEXES Labor Index: "Aircraft Engines and Engine Parts" Standard Industrial Classification 3724--Average hourly earnings (hereinafter referred to as "HE SIC 3724"), published by the US Department of Labor, Bureau of Labor Statistics, in "Employment and Earnings," Establishment Data: Hours and Earnings (Table B15: Average hours and earnings of production or nonsupervisory workers on private nonfarm payrolls by detailed industry). Material Index: "Metals and Metal Products" Code 10 (hereinafter referred to as "MMP-Index"), published by the US Department of Labor, Bureau of Labor Statistics, in "Producer Prices and Price Indexes" (Table 6: Producer prices and price indexes for commodity groupings and individual items).

Energy Index: "Fuels and Related Products and Power" Code 5 (hereinafter referred to as "EP-Index"), published by the US Department of Labor, Bureau of Labor Statistics, in "Producer Prices and Price Indexes" (Table 6: Producer prices and price indexes for commodity groupings and individual items). (Base year 1982 = 100.) ILFC-A321 Amdt. 6-25 25 4. REVISION FORMULA Pn = Pb [(0.60 HEn)/HEb + (0.30 MMPn)/MMPb + (0.10 EPn)/EPb] Where Pn = Revised Reference Price of a set of two (2) Propulsion systems at delivery of the Incremental Aircraft. Pb = Reference Price at economic conditions March 1988 HEn = HE SIC 3724 for the fourth month prior to the month of delivery of the Incremental Aircraft. HEb = HE SIC 3724 for March 1988 (= 13.58) MMPn = MMP-Index for the fourth month prior to the month of delivery of the Incremental Aircraft. MMPb = MMP-Index for March 1988 (= 115.4) EPn = EP-Index for the fourth month prior to the month of delivery of the Incremental Aircraft. EPb = EP-Index for March 1988 (= 65.9) In determining the Revised Reference Price each quotient ((0.60 HEn)/HEb, (0.30 MMPn)/MMPb and (0.10 EPn)/EPb) shall be calculated to the nearest ten thousandth (4 decimals). If the next succeeding place is five (5) or more the preceding decimal place shall be raised to the next higher figure. After final computation, Pn shall be rounded to the next whole number (0.5 or more rounded to 1). 5. GENERAL PROVISIONS 5.1 The Revised Reference Price at delivery of the Incremental Aircraft shall be the final price and will not be subject to further adjustments in the indexes. 5.2 If no final index value is available for any of the applicable months, the published preliminary figures will be the basis on which the Revised Reference Price will be computed. ILFC-A321 Amdt. 6-26 26 5.3 If the US Department of Labor substantially revises the methodology of calculation of the indexes referred to in this Appendix 3 or discontinues any of these indexes, the separate Seller shall, in agreement with International Aero Engines, apply a substitute for the revised or discontinued index, such substitute index to lead in application to the same adjustment result, insofar as possible, as would have been achieved by continuing the use of the original index as it may have fluctuated had it not been revised or discontinued. Appropriate revision of the formula shall be made to accomplish this result. 5.4 Should the above escalation provisions become null and void by action of the US Government, the Reference Price shall be adjusted to reflect increases in the cost of labor, material and fuel which have occurred from the period represented by the applicable Reference Price Indexes to the fourth month prior to the scheduled delivery of the Incremental Aircraft.
