(b) If a Participant is demoted during the Performance Period to a pay classification below those included within the groups of eligible employees set forth in Section 1(a) and such individual was a Participant for at least 180 days of the Performance Period, then such individual shall be entitled to an Award in an amount equal to the Payment Amount calculated in accordance with Section 4 hereof multiplied by a fraction the numerator of which is the number of days in the Performance Period that such individual was an eligible employee and the denominator of which is the total number of days in the Performance Period. (c) If an individual who was not, as of the Grant Date, eligible to participate hereunder is promoted on or before June 2001 to a pay classification that is included within the groups of eligible employees set forth in Section 1(a) and such individual is a Participant for at least 180 days of the Performance Period, then such individual shall be entitled to an Award in an amount equal to the Payment Amount calculated in accordance with Section 4 hereof multiplied by a fraction the numerator of which is the number of days in the Performance Period that such individual was an eligible employee and the denominator of which is the total number of days in the Performance Period. 6.4.
