NOTE 15.

SHARE BASED COMPENSATION

The Company's share-based compensation plan, the 2006 Equity Incentive Plan ("Equity Incentive Plan"), is administered by the compensation committee of the Board of Directors ("Board"), which selects persons to receive awards and determines the number of shares subject to each award and the terms, conditions, performance measures and other provisions of the award.

Our Board granted the following incentive stock option awards to executives or employees and nonstatutory stock option awards to directors or non-employees for the three and nine months ended September 30:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2013		2012		2013		2012 (3)
Incentive Stock Options (1)
Quantity		---		---		232,500		---
Weighted average fair value per share		---		---	$	0.24		---
Fair value		---		---	$	56,112		---

Nonstatutory Stock Options (2)
Quantity		---		---		735,000		---
Weighted average fair value per share		---		---	$	0.24		---
Fair value		---		---	$	177,388		---

	(1)	The Company did not award any incentive stock options for the three months ended September 30, 2013 and 2012, respectively.
	(2)	The Company did not award any nonstatutory stock options for the three months ended September 30, 2013 and 2012, respectively.
	(3)	The Company did not award any shared-based compensation for the nine months ended September 30, 2012.

We account for share-based compensation under FASB ASC Topic 718, Stock Compensation, which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees, consultants, and directors based on estimated fair values of the award on the grant date. We use the Black-Scholes option-pricing model to estimate the fair value of share-based awards with the following weighted average assumptions:

		Nine Months Ended September 30,
		2013	2012
Incentive Stock Options
	Expected volatility (1)	103.55%	---
	Risk-free interest rate % (2)	0.81%	---
	Expected term (in years)	5.0	---
	Dividend yield (3)	---	---
	Forfeiture rate	---	---

Nonstatutory Stock Options
	Expected volatility (1)	103.55%	---
	Risk-free interest rate % (2)	0.81%	---
	Expected term (in years)	5.0	---
	Dividend yield (3)	---	---
	Forfeiture rate	---	---

	(1)	Expected volatility assumption was based upon a combination of historical stock price volatility measured on a daily basis and an estimate of expected future stock price volatility
	(2)	Risk-free interest rate assumption is based upon U.S. Treasury bond interest rates appropriate for the term of the stock options.
	(3)	The Company does not currently intend to pay cash dividends, thus has assumed a 0% dividend yield.

Stock Options (Incentive and Nonstatutory)

The following table summarizes share-based compensation related to stock options for the three and nine months ended September 30:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2013		2012		2013		2012
Research and development	$	5,425	$	---	$	11,438	$	6,280
Selling, general and administrative		19,662		6,760		44,414		25,753
Total share-based compensation expense	$	25,087	$	6,760	$	55,852	$	32,033

At September 30, 2013, the balance of unearned share-based compensation to be expensed in future periods related to unvested stock option awards, as adjusted for expected forfeitures, is approximately $177,530. The period over which the unearned share-based compensation is expected to be recognized is approximately thirty months.

The following table summarizes the stock options outstanding and the number of shares of common stock subject to exercise as of September 30, 2013 and the changes therein during the nine months then ended:

	Stock Options			Weighted Average Exercise Price per Share
Outstanding as of December 31, 2012		158,409		$	12.32

Restricted Stock Awards

Restricted stock awards, which typically vest over a period of two to five years, are issued to certain key employees and are subject to forfeiture until the end of an established restriction period. We utilize the market price on the date of grant as the fair market value of restricted stock awards and expense the fair value on a straight-line basis over the vesting period.

The following table summarizes share-based compensation related to restricted stock awards for the three and nine months ended September 30:

	Three Months Ended September 30,					Nine Months Ended September 30,
	2013		2012			2013		2012
Research and development	$	---	$	( 391	)	$	444	$	2,814
Selling, general and administrative		---		1,143			547		3,392
Total share-based compensation expense	$	---	$	752		$	991	$	6,206

At September 30, 2013, the balance of unearned share-based compensation to be expensed in future periods related to restricted stock awards, as adjusted for expected forfeitures, is nil.

The following table summarizes the non-vested restricted stock awards outstanding and the number of shares of common stock subject to potential issue as of September 30, 2013 and the changes therein during the nine months then ended:

Summary of Plans

2006 Equity Incentive Plan

In March 2006, our Board adopted and our stockholders approved our Equity Incentive Plan, which initially provided for the issuance of up to 133,333 shares of our common stock pursuant to stock option and other equity awards. At the annual meetings of the stockholders held on May 8, 2007, December 17, 2009, June 15, 2010, June 14, 2012, and on June 13, 2013, our stockholders approved amendments to the Equity Incentive Plan to increase the total number of shares of common stock issuable under the Equity Incentive Plan pursuant to stock options and other equity awards by 266,667 shares, 200,000 shares, 200,000 shares, 400,000 shares, and 600,000 shares, respectively, to a total of 1,800,000 shares.

In December 2006, we began issuing stock options to employees, consultants, and directors. The stock options issued generally vest over a period of one to four years and have a maximum contractual term of ten years. In January 2007, we began issuing restricted stock awards to our employees. Restricted stock awards generally vest over a period of six months to five years after the date of grant. Prior to vesting, restricted stock awards do not have dividend equivalent rights, do not have voting rights and the shares underlying the restricted stock awards are not considered issued and outstanding. Shares of common stock are issued on the date the restricted stock awards vest.

As of September 30, 2013, we had granted options to purchase 1,376,167 shares of common stock since the inception of the Equity Incentive Plan, of which 1,014,907 were outstanding at a weighted average exercise price of $2.12 per share, and we had granted awards for 68,616 shares of restricted stock since the inception of the Equity Incentive Plan, of which none were outstanding. As of September 30, 2013, there were 715,647 shares that remained available for future grants under our Equity Incentive Plan.
