Share–Based Compensation

The Company has recognized share-based compensation expense from continuing operations of $202 thousand and $345 thousand for the years ended December 31, 2012 and 2011, respectively. The total non-cash, share-based compensation expense from continuing operations included in the consolidated statements of operations for the years ended is included in the following expense categories:

	Year Ended December 31,
(in thousands)	2012		2011
Cost of contract research, services	$	20	$	19
Cost of goods sold	32		74
Administrative and selling	150		252
Total share-based compensation	$	202	$	345

Share-based compensation expense from discontinued operations was $(7) thousand and $24 thousand for the years ended December 31, 2012 and 2011, respectively. No share-based compensation expense was capitalized during 2012 and 2011. Compensation expense related to stock options to be charged in future periods amounts to approximately $113 thousand at December 31, 2012 and will be recognized over a weighted-average period of 1.27 years as follows:

For the years ended December 31,	Expected Compensation Expense

2013	$	85

	$	113

The Company estimates forfeitures at the time of grant and revises, if necessary, in subsequent periods if actual forfeitures differ from those estimates in order to derive the Company’s best estimate of awards ultimately expected to vest.  Forfeitures represent only the unvested portion of a surrendered option and are typically estimated based on historical experience.

At December 31, 2012, the Company had outstanding options under two stock option plans: the 1996 Equity Incentive Plan (the “1996 Plan”) and the 2007 Stock Equity Plan (the “2007 Plan”, together the "Plans"). Both Plans were approved by stockholders and provided that the Board of Directors may grant options to purchase the Company’s common stock to key employees and directors of the Company. Incentive and non-qualified options must be granted at least at the fair market value of the common stock or, in the case of certain optionees, at 110% of such fair market value at the time of grant. The options may be exercised, subject to certain vesting requirements, for periods up to ten years from the date of issue. The 1996 Plan expired with respect to the issuance of new grants as of December 10, 2006.  Accordingly, future grants may be made only under the 2007 Plan.

A summary of options outstanding under the Plans as of December 31, 2012 and changes during the twelve month period ended December 31, 2012 is as follows: 

	Number of Shares		Weighted Average Exercise Price		Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value
						(in thousands)
Options outstanding at December 31, 2011	793,107		$	6.40
Granted	40,000		$	0.75
Exercised	—		$	—
Cancelled/expired	(188,661	)	$	7.11
Options outstanding at December 31, 2012	644,446		$	6.21	5.82	$	—
Options vested and exercisable at December 31, 2012	575,696		$	6.35	5.66	$	—
Options vested and expected to vest at December 31, 2012	640,234		$	6.36	5.65	$	—
Options available for future grant at December 31, 2012	554,300

The aggregate intrinsic value in the table above represents the total intrinsic value, based on the Company’s closing stock price of $0.50 as of December 31, 2012, which would have been received by the option holders had all option holders exercised their options as of that date. The total intrinsic value of options exercised was approximately zero and $3 thousand for the years ended December 31, 2012 and 2011, respectively. The total intrinsic value of options expected to vest at December 31, 2012 was approximately zero, and the weighted average remaining contractual life of outstanding options that are expected to vest is 5.56 years.

At December 31, 2012, the Company has outstanding under its 1996 Plan and 2007 Plan, an aggregate 243,746 non-qualified stock options held by the non-employee directors of the Company for the purchase of common stock at an average exercise price of $6.65 per share.

The per-share weighted-average fair value of stock options granted was $1.78 and $2.62 for the years ended December 31, 2012 and 2011, respectively, on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

Year	Expected Dividend Yield	Risk-Free Interest Rate		Expected Option Life	Expected Volatility Factor
2012	—	0.71	%	5.10 years	93.3	%
2011	—	1.76	%	5.09 years	78.0	%

The risk free interest rate reflects treasury yields rates over a term that approximates the expected option life. The expected option life is calculated based on historical lives of all options issued under the plan.  The expected volatility factor is determined by measuring the actual stock price volatility over a term equal to the expected useful life of the options granted.
