     In May 2007, we issued 1,120,000 shares of Common Stock and warrants in a private placement of public equity. The warrants were exercisable into 280,000 shares of Common Stock at an exercise price of $16.20 per share, which were exercisable as of the date of issuance and expired five years after the date of issuance, in May 2012. There are no remaining warrants available for exercise for our Common Stock as of June 30, 2012.
