     ESOP Participant who is a member of the IAM Employee Group

     clauses (ii), (iv), (v), (vi) or (vii) of Section 5.4(a) of
     the ESOP, (C) were based on Compensation rather than the
     definition of compensation in the ESOP, and (D) for Plan
     Years beginning on or after January 1, 1995, by including
     the shares designated for inclusion in the Hypothetical
     Share Number for the ESOP Participant on account of the

     Appendix A to the ESOP; and"

          8.  The first sentence of Section 2.4(c) is amended to
read as follows:

     "For each ESOP Participant, the difference, if any, between
     the Hypothetical Share Number and the Actual Share Number
     shall be referred to as the Tentative Allocation; provided,
     however, that, except for purposes of subsection (f) and the
     Special Annual Allocation for the 1995 Plan Year, the
     Tentative Allocation for any member of the IAM Employee
     Group shall be zero."

          9.  Section 4.2(i) is amended to read as follows:
     "(i) Notwithstanding the above and the definition of
     "Committee", clauses (a), (b) and (c) shall be disregarded
     with respect to any issue involving Voting Shares and

     this Plan if any Voting Shares or Convertible Shares are
     allocated to an Account of a Participant who is a member of
     the IAM Employee Group."

          10.  Section 5.1 is amended to read as follows:

     "5.1.  Amendment.  While the Company expects and intends to

     time, except that no amendment may be adopted, without the
     approval of ALPA, provided, that, with respect to amendments
     adopted which are described in Section 13.1(b) or (d) of the
     ESOP (which subsections shall be treated as appropriately
     modified to the extent necessary to reflect the
     circumstances of this Plan) the need for joint approval
     shall be modified, and provided further that no amendment
     which would affect the allocation of the Class M Voting
     Shares or Convertible Preferred Shares to members of the IAM
     Employee Group shall be adopted without the approval of the
     IAM."

          11.  The second sentence of Section 5.2 is amended to
read as follows:

     "Notwithstanding the preceding sentence, the approval of the
     IAM will only be required if Class M Voting Shares reserved
     for allocation have been transferred or contributed to the
     Supplemental Trust, or if Convertible Preferred Shares are
     allocated to Accounts of members of the IAM Employee Group
     at the time of termination."
