If each of the Performance Measures has been met, the amount of the actual Award will be made pursuant to the provisions of Section 6.2.

Notwithstanding anything to the contrary elsewhere herein, if a Change of Control shall occur, (a) each Long-Term Performance Period that has not yet ended shall end as of the date the Change of Control occurs and Awards shall be calculated for each such Long-Term Performance Period as of such date based on the Company’s performance through such date and (b) all Participants who are employed by the Company on the date the Change of Control occurs shall receive a pro rata Award based on such shortened Long-Term Performance Period (or, in the discretion of the Committee, the cash value of such pro rata Award), if any, as soon as practicable. Notwithstanding the foregoing, in the event a Participant experiences a Termination of Service within six months after such Change of Control and such Termination of Service is in connection with such Change of Control, then such Participant shall be entitled to an additional Award under this Program at such time in an amount equal to the excess, if any, of the amount determined pursuant to the preceding sentence (assuming the amount in (a) was calculated based on Superior Target), over the amount determined pursuant to the preceding sentence (assuming the amount in (a) was calculated based on the Company’s actual performance.
