(2) Phantom stock units will be converted to cash per my elections on or within 5 years of my termination of employment (subject to 6-month delay if necessary to comply with IRC 409A), or upon my death or Disability.
(3) I also receive phantom stock units as a result of my participation in an excess benefit plan. This total includes 18,678.9090 units in such plan in addition to units held through my account balance in a deferred compensation plan. I also receive dividends.
