Appendix 1 to Amendment 3 EXHIBIT B

5.2 Substitution of Indexes for Airframe Price Revision Formula

If:

(i) the United States Department of Labor substantially revises the methodology of calculation of the Labor Index or the Material Index as used in the Airframe Price Revision Formula, or

(ii) the United States Department of Labor discontinues, either temporarily or permanently, such Labor Index or such Material Index, or

(iii) the data samples used to calculate such Labor Index or such Material Index are substantially changed;

the Seller shall select a substitute index for inclusion in the Airframe Price Revision Formula (the "Substitute Index").

The Substitute Index shall reflect as closely as possible the actual variance of the Labor Costs or of the material costs used in the calculation of the original Labor Index or Material Index as the case may be.
