The weighted-average fair market value per share of options granted under our stock option plans during fiscal 2013 and 2012 was $6.02 and $10.37, respectively.

We granted 6,809 shares of restricted stock to the non-employee members of our Board of Directors in June 2013, and recorded a stock-based compensation expense of $65,000.  We granted 5,798 shares of restricted stock to the non-employee members of our Board of Directors in 2012, and recorded a stock-based compensation expense of $50,000. The restricted stock will vest over a one-year period measured from the date of the annual meeting of stockholders with one quarter of the shares included in such Director Grant vesting on each of the dates that are three months, six months, nine months and twelve months from the annual meeting, so long as each board member continues to serve as a member of our board of directors on such vesting date.

As of December 31, 2013, total unrecognized compensation cost related to unvested stock options was$2,394,000, which is expected to be recognized over the remaining weighted-average vesting periods of 1.64 years. During the year ended December 31, 2013 and 2012, we have received cash of $484,000 and $2,167,000, respectively from the exercise of stock options and employee stock purchases.
