(1)	Pursuant to the Management Agreement these awards are subject to both time (25% of the Award) and performance-based (75% of the Award) vesting. The portion of the Award subject to time-based vesting shall vest in equal installments of 25% per year over a four year period, beginning on June 1, 2009, so long as the member of management continues to be employed by the Company. The portion of the Award subject to performance-based vesting shall vest based on the performance of the Company over a four-year Performance Cycle as measured by Total Shareholder Return of the Company compared to the Total Shareholder Return of the Company?s Peer Group. The amount of the performance-based portion of the Award that will vest at the end of the Performance Cycle will depend upon the performance level obtained by the Company (Distinguished, Target, Threshold or Below Threshold).
(2)	Restricted Stock Units will be paid to the grantee in cash upon vesting, unless one of the following occurs: 1) the shareholders of the issuer approve an amendment to the issuer's Amended & Restated 2000 Stock Incentive Plan to increase the number of shares of common stock that may be issued under the plan or 2) additional shares become available to the plan through stock option expirations and/or employee terminations, in which case the grantee may receive shares of common stock in lieu of cash.
