The Performance Objectives, Bonus Amount and Performance Period shall be set forth in an Award Agreement approved by the Committee.

7. TERMINATION OF EMPLOYMENT; CHANGE IN CONTROL

7.1. Notwithstanding the requirement to be employed on the last day of the Performance Period in order to be eligible for payment of the Bonus Amount described in Section 6.2, if a Participant’s employment with the Company is terminated during a Performance Period for which Performance Objectives have been attained for any reason other than discharge for Cause, the Committee, in its sole discretion, may determine that the Participant is entitled to a portion of the Bonus Amount that is determined at the end of the Performance Period and payable at the time specified in Section 6.2. This provision only provides discretion in determining whether to waive the employment requirement. In the event the employment requirement is waived, the Bonus Amount shall be a pro rata amount based on the number of months of the Participant’s employment during the Performance Period with the month of termination counting as a full month of employment.

7.2.

9. COMPLIANCE WITH SECTION 409A OF THE CODE

Each Award granted under this Plan is intended to be either exempt from or in compliance with the requirements of Section 409A of the Code, and the Plan shall be interpreted accordingly. Without limiting the foregoing, the Bonus Amount shall not be deferred, accelerated, extended, paid out, settled, adjusted, substituted, exchanged or modified in a manner that would cause the Award to fail to satisfy the conditions of an applicable exception from the requirements of Section 409A of the Code or otherwise would subject the Participant to the additional tax imposed under Section 409A of the Code. If the Participant is a “specified employee” within the meaning of Treasury Regulation Section 1.409A-1(i) as of the date of the Participant’s separation from service (within the meaning of Treasury Regulation Section 1.409A-1(h)), any Award, to the extent such Award constitutes non-qualified deferred compensation subject to Section 409A of the Code and required to be delayed pursuant to Section 409A(2)(B)(i) of the Code (after taking into account any exclusions applicable to such payments under Section 409A of the Code), shall not be made until the first business day after (i) the expiration of six (6) months from the Participant’s separation from service or (ii) if earlier, the date of Participant’s death.
