Options and Deferral Periods.
(a) A Participant may allocate a portion, or all, of a Deferred Amount to Options, if such hypothetical investment is made available by the Executive Committee (see Section 7.02(c)). When a Participant allocates Deferred Amounts to Options, the Participant must elect a Deferral Period, which must be at least three years but no more than ten years beginning on the date the Deferred Amount (or last installment of the Deferred Amount in the case of salary), is credited to the Deferral Account. The Deferral Period will also determine the term of the Option; however, if the minimum Deferral Period of three years is chosen, then the Option term will be four years.
(b) The allocation to Options and establishment of a corresponding Deferral Period creates an Option Sub-Account. There is no limit on the number of Option Sub-Accounts which a Participant may maintain.
(c) Option Sub-Accounts established prior to January 1, 2004 will be accelerated and combined with Retirement payments in progress (or, if none, then paid in accordance with the Participants Form of Payment election for the Option Sub-Account) in the event of exercise of the Option following Retirement. For Option Sub-Accounts established on or after January 1, 2004, Option Sub-Account distributions shall not be accelerated due to Retirement or exercise of the Option following Retirement.
