The following table sets forth the computation of basic and diluted net income per common share (in thousands, except per share amounts):

	Three Months Ended
	March 31, 2012							March 31, 2011
	Continuing			Discontinued		Net		Continuing		Discontinued		Net
	Operations			Operations		Income		Operations		Operations		Income

BASIC

Net income (loss)	$	5,349	$	-	$	5,349	$	26,685	$	(7,325)	$	19,360
Less: income (loss) allocated to
participating securities		-		-		-		799		-		562
Net income (loss) available to
common stockholders		5,349		-		5,349		25,886		(7,325)		18,798
Weighted average number of common
shares outstanding		57,109		-		57,109		59,124		59,124		59,124
Basic net income (loss) per
common share	$	0.09	$	-	$	0.09	$	0.44	$	(0.12)	$	0.32

DILUTED

Net income (loss)	$	5,349	$	-	$	5,349	$	26,685	$	(7,325)	$	19,360
Less: income (loss) allocated to
participating securities		-		-		-		799		-		562
Net income (loss) available to
common stockholders		5,349		-		5,349		25,886		(7,325)		18,798
Less:
Undistributed earnings allocated to
unvested stockholders		-		-		-		(687)		-		(457)

unvested stockholders		-		-		-		683		-		454
Add:

related to Old Notes		-		-		-		666		-		666
Net income (loss) assuming dilution	$	5,349	$	-	$	5,349	$	26,548	$	(7,325)	$	19,461

Weighted average number of common
shares outstanding		57,109		-		57,109		59,124		59,124		59,124
Effect of dilutive securities:
Old Notes		-		-		-		5,823		-		5,823
New Notes		-		-		-		4		-		4
Stock options		1,410		-		1,410		430		-		430
Weighted average number of common
shares assuming dilution		58,519		-		58,519		65,381		59,124		65,381
Diluted net income (loss) per
common share	$	0.09	$	-	$	0.09	$	0.41	$	(0.12)	$	0.30

Diluted net income per common share must be calculated using the “if-converted” method. Diluted net income per share using the “if-converted” method is calculated by adjusting net income for tax-effected net interest on the Old Notes and New Notes, divided by the weighted average number of common shares outstanding assuming conversion.

Unvested share-based payment awards that contain rights to receive nonforfeitable dividends or dividend equivalents (whether paid or unpaid) are participating securities, and thus, are included in the two-class method of computing earnings per share. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that would otherwise have been available to common stockholders. Restricted stock granted to certain employees by the Company (see Note 3) participate in dividends on the same basis as common shares, and these dividends are not forfeitable by the holders of the restricted stock. As a result, the restricted stock grants meet the definition of a participating security.

The diluted net income per common share computation for the three months ended March 31, 2012 excludes 2,363,691 shares of stock that represented outstanding stock options whose impact would be anti-dilutive. The diluted net income per common share computation for the three months ended March 31, 2012 also excludes 5,822,551 and 4,685 shares of common stock, issuable upon conversion of the Old Notes and New Notes, respectively, whose impact would be anti-dilutive. The two-class method for computing diluted net income per common share for the three months ended March 31, 2012 is also not presented, as its impact would be anti-dilutive.

The diluted net income per common share computation for the three months ended March 31, 2011 excludes 5,032,879 shares of stock that represented outstanding stock options whose impact would be anti-dilutive.

Due to the net loss from discontinued operations during the three months ended March 31, 2011, diluted earnings per share and basic earnings per share from discontinued operations are the same, as the effect of potentially dilutive securities would be anti-dilutive.
