5.  Computation of Basic and Diluted Net Earnings (Loss) Per Share

Basic net earnings (loss) per share is computed using the weighted average number of common shares outstanding during the period, excluding any unvested restricted stock. Diluted net earnings (loss) per share is computed using the weighted average number of common shares, and if dilutive, potential common shares outstanding, as determined under the treasury stock and if-converted method, during the period. Potential common shares consist of unvested restricted stock, common shares issuable upon the exercise of stock options, common shares issuable upon the exercise of the Warrant and common shares issuable upon the conversion of the Note.  The following are the share amounts utilized to compute the basic and diluted net earnings (loss) per share for the three months and nine months ended September 30, 2011 and 2010:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2011			2010			2011			2010
Basic shares:
Weighted average common shares outstanding		46,103,362			45,382,729			45,983,971			45,272,244
Weighted average unvested restricted stock		(26,316	)		(226,762	)		(67,658	)		(299,624	)
Basic shares		46,077,046			45,155,967			45,916,313			44,972,620
Diluted Shares:
Basic Shares		46,077,046			45,155,967			45,916,313			44,972,620
Weighted average dilutive securities		1,313,650			-			2,057,747			-
Dilutive Shares		47,390,696			45,155,967			47,974,060			44,972,620

For the three and nine months ended September 30, 2011, 11.7 million and 11.2 million anti-dilutive potential shares of common stock have been excluded from the calculation of diluted earnings per share, respectively.  For the three and nine months ended September 30, 2010, 4.7 million and 4.5 million anti-dilutive potential shares of common stock have been excluded from the calculation of diluted loss per share, respectively.
