At May 31, 2012 and November 30, 2011, the Company had 945,594 warrants issued and outstanding. The warrants were issued to stockholders that invested in the Company’s initial private placements and became exercisable on February 7, 2007 (the closing date of the Company’s initial public offering of common shares), subject to a lock-up period with respect to the underlying common shares. Each warrant entitled the holder to purchase one common share at the exercise price of $15.00 per common share. Warrants were issued as separate instruments from the common shares and are permitted to be transferred independently from the common shares. The warrants have no voting rights and the common shares underlying the unexercised warrants have no voting rights until such common shares are received upon exercise of the warrants.

On April 8, 2011, a proposal was approved by the Company’s stockholders which allowed the Company to amend the exercise price of its outstanding warrants from $15.00 per common share to an amount equal to the greater of the market price of the Company’s common shares on the New York Stock Exchange, each as determined at the end of the fiscal quarter immediately following approval of the proposal, plus 7.0 percent, and to extend the expiration date of such warrants by one year. Based on these guidelines, the exercise price of the warrants was changed to $11.41 per common share as of May 31, 2011. All warrants expire on February 6, 2014. This modification was not material to the financial statements.
