Explanation of Responses:
1. On April 3, 2007, the date of the exercise of the four warrants, the Issuer's common stock had a value of $17.20 per share, and thus the four warrants allowing State Farm Mutual Automobile Insurance Company ("State Farm") to purchase the Issuer's common stock at less than $17.20 per share were "in-the-money." State Farm chose to exercise its four warrants on April 3, 2007 by making a "net issue election" as allowed by each warrant. Under this election, State Farm elected to pay the conversion or exercise price of the warrants by tendering shares of common stock to be received upon conversion. Therefore, State Farm received fewer shares than each warrant entitled it to receive if State Farm had paid the conversion or exercise price in cash.
2. These warrants, which entitled the holder to purchase shares of the Issuer's common stock at a set price before the warrant's specified expiration date, were fully vested and exercisable.
