Effective as of January 1, 1995, new Section 21.5 is hereby added to the Plan to read as follows: "21.5 GATT Code Section 415(b)(2)(E) Transition Rule. (a) Effective as of January 1, 1995, the Plan is amended to comply with Code Section 415(b)(2)(E), as amended by the Retirement Protection Act of 1994 under the General Agreement on Tariffs and Trades, as amended (`GATT'), but applied as provided in this Section 21.5 prior to January 1, 2000, in accordance with the transition rule under Rev. Rul. 98-1, 1998-2 I.R.B. 5, 98-1 C.B. 249, as described in this Section 21.5. (b) In the case of a Member as of January 1, 1995, the application of the limitations under Article XXI of the Plan shall not cause the maximum permissible amount for such Member under the Plan to be less than the Member's Accrued Benefit as of December 31, 1999 (the `Freeze Date'), as determined for each possible annuity starting date and optional form of benefit as of such Freeze Date after applying Section 415(b) of the Code as in effect on December 7, 1994, including the participation requirements of Code Section 415(b)(5) (`Old Law Benefit'). A Member's Old Law Benefit shall not increase, but may decrease, after the Freeze Date. Any amendment changing the actuarial assumptions under Section 21.1 of the Plan that is adopted and effective prior to the Freeze Date shall be included when determining a Member's benefit accrued as of the Freeze Date. In applying the Code Section 415(b) limitation in determining a Member's Accrued Benefit, if the Member has an Old Law Benefit, such benefit will be determined using `Method 2' under Rev. Rul. 98-1, Q&A 14. The applicable interest rate and mortality table used to determine the annual benefit that is equivalent to the Old Law Benefit shall be based on (i) the Plan provisions as in effect on December 7, 1994, if the determination is being made before January 1, 2000 (the `Final Implementation Date'), and (ii) Plan provisions as in effect on such date of determination if the determination is being made on or after the Final Implementation Date." 2. Effective as of January 1, 1999, the second sentence of the first paragraph and the second paragraph of Article II of the Plan are hereby amended to read as follows: "Each other Employee who is not (i) a `leased employee' (as defined in Section 414(n)(2) of the Code, subject to Code Section 414(n)(5)), (ii) designated, compensated, or otherwise classified or treated as an independent contractor or a leased employee by an Employer or an Affiliate, or (iii) a non-resident alien who receives no United States source earned income from the Employer shall participate in the Plan on the later of January 1, 1999, or the date on which the Employee completes one hour of service in accordance with Section 3.2. Leased employees, including leased employees as defined in Code Section 414(n)(2), subject to Code Section 414(n)(5), and any other person performing services pursuant to an arrangement between an Employer or an Affiliate and a third party, are not eligible to participate in the Plan." 3.
