Basic net income (loss) per share is computed using the weighted-average number of common shares outstanding. The dilutive effect of common shares potentially issuable under outstanding options, warrants and restricted shares is included in diluted earnings per share. The computations of basic and diluted per share data were as follows:

	Three months ended					Six months ended
	June 30,					June 30
	2011		2010			2011		2010
Net income (loss)	$	200	$	(2,229	)	$	609	$	(6,632	)

For the three and six months ended June 30, 2011 and 2010, options, warrants and restricted shares to purchase 20,121,396 and 30,574,290 common shares, respectively, were not included in the computation of diluted income (loss) per share as the effect would be anti-dilutive.
