The individual has provided the Company, and undertakes to provide to the staff of the Securities and Exchange Commission or any security holder of the Company, upon request, full information regarding the number of shares sold at each separate price.
3.	Represents the weighted average of sale prices, ranging from $68.38 to $69.34.
