NOTE B—STOCK BASED COMPENSATION

Stock Options

Compensation expense related to stock options and restricted stock awards recognized in operating results (general and administrative expenses) was approximately $0.3 million and $0.4 million for the three months ended March 31, 2013 and March 31, 2012, respectively.

The following assumptions were used to value stock options calculated using the Black-Scholes options pricing model:

	Three months ended March 31,
	2013		2012
Dividend yield	0	%	0	%
Expected volatility	71.0	%	74.0	%
Risk-free interest rate	0.5	%	0.5	%
Expected life	3.5 years		3.5 years

			Weighted		Weighted
			Average		Average	Aggregate
	Number		Exercise		Remaining	Intrinsic Value
	of Options		Price		Term (in years)	(in thousands)
Outstanding at December 31, 2012	1,989,309		$	2.48
Granted	340,250		2.75
Exercised	(171,547	)	1.11
Forfeited or expired	(191,809	)	7.99
Outstanding at March 31, 2013	1,966,203		$	2.11	2.46	$	2,467
Exercisable at March 31, 2013	1,354,953		$	1.78	1.48	$	2,207

The total intrinsic value of options exercised during the three months ended March 31, 2013 and 2012 were approximately $317,000 and $107,000 respectively.

As of March 31, 2013 total unrecognized stock-based compensation expense related to non-vested stock options was approximately $0.8 million, which we expect to recognize over a weighted average period of 3.0 years.

Restricted Shares

Restricted share activity for the three months ended March 31, 2013 was as follows:

	Shares		Weighted Average Fair Value
Outstanding at December 31, 2012	1,606,460		$	2.54
Granted	886,331		1.87
Vested	(229,201	)	3.91
Forfeited	(123,989	)	3.19
Outstanding at March 31, 2013	2,139,601		$	2.08

Restricted stock awards for executive officers and employees vest ratably over three years. Fair value of our restricted shares is based on our closing stock price on the date of grant.  As of March 31, 2013, total unrecognized stock-based compensation expense related to non-vested restricted shares was $4.1 million, which is expected to be recognized over a weighted average period of approximately 1.7 years.
