Explanation of Responses:

( 1 )On February 13, 2008 the reporting person ordered the sale of 33,132 shares of stock. The broker improperly executed the sale order on February 13th and the sale transaction was rescinded through the broker?s error account and therefore did not occur for the reporting person?s account. This filing reflects the completion of the ordered sale on February 15, 2008.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
