Weighted average assumptions to estimate the fair value of share based awards

We use the Black-Scholes option-pricing model to estimate the fair value of share-based awards with the following weighted average assumptions:

	Six Months Ended June 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.
