12. Share-based Compensation

Our 2006 Stock Option and Incentive Plan allows for granting of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock units, unrestricted stock awards, and deferred stock awards to our officers, employees, directors, and consultants.

The components of share-based compensation expense were as follows:

	Three months ended June 30,				Six months ended June 30,
	2011		2010		2011		2010
	(in thousands)
Stock option awards to employees	$	138	$	97	$	271	$	188
Restricted common stock awards		129		129		259		253
Total share-based compensation	$	267	$	226	$	530	$	441

We have computed the fair values of employee stock options for option grants issued during the six months ended June 30 2011 and 2010, respectively, using the Black-Scholes option model with the following assumptions:

	2011			2010
Dividend yield		1.2	%		0.0	%
Volatility		67.3	%		75.7	%
Risk-free interest rate		2.1	%		2.3	%
Weighted average expected option term (in years)		5.0			5.0
Weighted average fair value per share of options granted	$	3.42		$	2.94

We did not issue restricted stock units in the six months ended June 30, 2011. The weighted-average fair value per share of restricted stock unit grants issued for the six months ended June 30, 2010 was $4.84.
