Explanation of Responses:
( 1)	The number of shares of performance-based restricted stock awards granted to the employee is based on the full theoretical maximum value (the "theoretical maximum"). Although the actual shares earned could range from 0% to 100% of the theoretical maximum depending upon the Company's achievement of growth targets established by the Board of Directors, the employees will be able to vote shares up to the full theoretical maximum until the determination of the actual amount earned. After such determination, the employee will be able to vote only the number of shares so earned.
( 2)	Stock Option Award vests equally over 4 years.
( 3)	Ammendment filed to correct the total amount of securities owned.
