The Participant's Account shall be valued as of the last business day of the month in which the Participant terminates; provided, however, if the Participant terminates within five (5) business days prior to the last day of such month, the Participant's Account may be valued as of the last business day of the following month, at the Committee's discretion. Such distribution shall be paid in a single lump sum cash payment as soon as administratively practicable following the valuation date. With regard to any distribution made under this Article, the market value of any shares of Phantom Common Stock credited to a Participant's Account shall be based on the Sales Price. No portion of a Participant's Account shall be distributed in Common Stock. III.
