The State could terminate the Agreement in whole or in part by giving at least two
                  years advance notice in writing to SSA. The coverage must have been in effect at least
                  five years before SSA receipt of the notice. This meant five years actual coverage
                  from the effective date of the first coverage and not five years from the date of
                  execution of the Modification that provided the coverage. The two-year period ran
                  from the date the notice was mailed or delivered to SSA and not the date of receipt.
               
               The termination could have applied to any absolute coverage group. For example, coverage
                  for a proprietary function coverage group could have been terminated without terminating
                  coverage for the governmental function coverage group. This could have been done even
                  though the coverage groups were not separately identified when the coverage was provided.
                  A retirement system coverage group was not a coverage group for termination purposes.
