DEFERRAL OF ELIGIBLE COMPENSATION AND GAIN SHARES
Section 6.01 Elective Deferred Incentive Compensation. The Deferred Amount of a Participant with respect to each Plan Year of participation in the Plan shall be credited by the Administrative Committee to the Participants Deferral Account or Sub-Account as and when such Deferred Amount would otherwise have been paid to the Participant. To the extent that the Company is required to withhold any taxes or other amounts from the Deferred Amount pursuant to any state, Federal or local law, such amounts shall be taken out of compensation to the Participant that is not deferred under this Plan. In the event a Participants deferral election results in insufficient non-deferred compensation from which to withhold taxes in accordance with applicable law, the Deferred Amount shall be reduced as necessary to allow the Company to satisfy tax withholding requirements.
Section 6.02 Vesting of Accounts. Except as provided in Section 8.06, a Participant shall be 100% vested in his/her Account at all times.
Section 6.03 Gain Shares. The gain from the exercise of the Option which the Participant elects to defer under the Plan as Phantom Share Units shall be credited by the Administrative Committee to the Participants Gain Share Account as of the Date of Exercise.
