B. Current Break in Service Rule: Effective January 1, 1987

The current Break in Service rule, which became effective as of January 1, 1987, provides that your previously earned Credited Service and Pension Credit since any prior Break in Service is not cancelled unless you incur the greater of either:

1. Five consecutive one year Breaks in Service as described in Subsection A.3 above, or
2. Consecutive one year Breaks in Service as described in Subsection A.3. above in excess of the number of years and months of Credited Service or Pension Credit you accumulated prior to the commencement of such Break in Service.

Under these rules and the Plan's vesting schedule, a non-vested Participant who has earned an hour of service after December 31, 1997, will only experience a Permanent Break in Service if the number of years of Breaks in Service equals or exceeds five years. This is because the Participant will become vested upon accumulating five years of Pension Credit or Credited Service, and the Break in Service rules will then no longer apply to that Participant.

Based on past experience with the Plan, in all but the most unusual of circumstances, the provisions preventing a Break in Service if you earned 300 or more hours of Pension Credit in two consecutive calendar years are more liberal than the alternative of determining whether a Break-in-Service occurred on the basis of Credited Service.
