~~Item~~ The 9Performance Shares were granted as a means to further align the interests of the Executive Officers with those of the Company’s shareholders and as a means of retention.01 The Performance Shares vest based upon the attainment by the Company of specified earnings performance growth targets. ~~Financial~~Each ~~Statements~~Performance Share has a purchase price of Par Value. The vesting of the Performance Shares will terminate immediately upon an Executive Officer’s termination from the Company. If the Executive Officer remains employed by the Company for five years after the grant date, all unvested Performance Shares automatically become vested. In the event of a change in control resulting in cash payments to the Company’s shareholders, unvested Performance Shares are exchanged for an incentive payment, disbursed in four equal installments every six months over a two year period provided that the Executive Officer remains employed by the Company. The incentive payment is calculated by multiplying the number of Performance Shares forfeited by the amount of cash payable with respect to each share of Common Stock in a change of control. In the event of a change in control not resulting in cash payments to the Company’s shareholders, unvested Performance Shares are intended to serve as an incentive and ~~Exhibits~~will vest in four equal installments every six months over a two year period provided that the Executive Officer remains employed by the Company. These incentives accelerate if, following a change in control, the Executive Officer is involuntarily terminated (other than for cause) or upon a qualified voluntary termination.
