During the term of the Plan, the Administrator may establish performance periods (each, a “Performance Period”) and grant awards for each Performance Period.  Unless otherwise determined by the Administrator, each Performance Period shall be 12 fiscal quarters.   For each Performance Period, the Administrator shall determine:

(a)the target amounts of net income and return on capital or the target amounts for any other financial measures relating to the Company selected by the Administrator (the “Financial Measures”) and how the Financial Measures are defined and calculated;

(b)the Participants for that Performance Period and the target cash amount for each Participant if the Company achieves the target amounts under the Financial Measures, subject to the other conditions of the award;

(c)the method or formula for determining cash amounts to be paid to Participants if the results under the Financial Measures during the Performance Period are more or less than the target amounts;

Payments under an award may be subject to any other terms and conditions approved by the Administrator and set forth in the applicable award agreement.

7.    Payment of Awards. Following the availability of the Company’s consolidated financial statements for the final fiscal quarter of each Performance Period and prior to the applicable vesting date for awards during that Performance Period, the Administrator shall make all calculations necessary to determine amounts achieved for the Performance Period under the applicable Financial Measures and the corresponding amounts to be paid to the Participants.
