Compensation based options and restricted stock totaling 1.8 million and 1.9 million shares were granted for the three and nine month periods ended March 31, 2012, respectively.
For the three and nine months ended March 31, 2013, stock based compensation of $585,000 and $1.6 million, respectively, was reflected as an increase to additional paid in capital. Stock based compensation for the three and nine months ended March 31, 2013, was all employee related. For the three and nine months ended March 31, 2012, stock based compensation of $308,000 and $881,000, respectively, was reflected as an increase to additional paid in capital. Of the stock based compensation for the three and nine months ended March 31, 2012, $308,000 and $748,000, respectively, was employee related and none and $133,000, respectively, was non-employee related.

risk-free interest rates of between 0.46 and 1.19 percent for the nine months ended March 31, 2013 and between 0.93 and 0.97 percent for the nine months ended March 31, 2012;
2.
dividend yield of -0- percent;
3.
expected life of 3 to 6 years; and
4.
a volatility factor of the expected market price of our common stock of between 113 and 127 percent for the nine months ended March 31, 2013 between 129 and 137 percent for the nine months ended March 31, 2012.
