5.    GENERAL PROVISIONS

5.1   Roundings

      (i)   ECIn and ICn shall be calculated to the nearest tenth (1 decimal)

      (ii)  Each quotient (ECIn/ECIb) and (ICn/ICb) shall be calculated to the
            nearest ten-thousandth (4 decimals).

      (iii) The final factor shall be rounded 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 nearest higher figure.

      After final computation Pn shall be rounded to the nearest whole number
      (0.5 rounds to 1).

5.2   Final Index Values

      The revised Reference Price at the date of Aircraft Delivery shall be the
      final price and shall not be subject to any further adjustments in the
      indexes.

      If no final index values are available for any of the applicable month,
      the then published preliminary figures shall be the basis on which the
      Revised Reference Price shall be computed.

      If the US Department of Labor substantially revises the methodology of
      calculation or discontinues any of the indexes referred to hereabove, the
      Seller shall reflect the

                                   Page 13/14
<PAGE>

      substitute for the revised or discontinued index selected by INTERNATIONAL
      AERO ENGINES, 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   Annulment of Formula

      Should the above escalation provisions become null and void by action of
      the US Government, the price shall be adjusted due to increases in the
      costs of labor and material which have occurred from the period
      represented by the applicable Reference Price Indexes to the Fifth (5th),
      Sixth (6th) and Seventh (7th) months averaged prior to the scheduled
      Aircraft Delivery.

5.5   Limitation

      Should the revised Reference Price be lower than the Reference Price, the
      final price shall be computed with the Reference Price.
