Note 2 — Net Loss per Common Share

The Company’s basic net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding for the period and, if there are dilutive securities, diluted loss per share is computed by including common stock equivalents which includes shares issuable upon the exercise of stock options, net of shares assumed to have been purchased with the proceeds, using the treasury stock method.

A summary of the Company’s calculation of loss per share is as follows:


	Three Months Ended						Nine Months Ended
	September 30,						September 30,
	2011			2010			2011			2010

Net loss	$	(24,983	)	$	(1,393	)	$	(34,277	)	$	(3,314	)

As of September 30, 2011 and 2010, there were 5.7 million and 6.0 million shares of the Company’s common stock, respectively issuable upon the exercise of stock options and warrants and vesting of restricted stock that were excluded from the calculation of diluted net loss per share because their effect would have been antidilutive.
