The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value that would have been received by the option holders had they all exercised their options on March 31, 2013. This amount changes based on the fair market value of our stock. During the three months ended March 31, 2013 and 2012, the aggregate intrinsic value of options exercised under our stock option plans was $2.4 million and $89,000 respectively. Total fair value of options vested during the three months ended March 31, 2013 and 2012 was $471,000 and $1.0 million, respectively. 

At March 31, 2013, there was $2.6 million of unrecognized compensation cost related to existing options outstanding which is expected to be recognized over a weighted average period of 1.7 years.

Employee Stock Purchase Plan

                In the second quarter of 2011, to advance the interests of the Company and its stockholders by providing an incentive to attract, retain and reward eligible employees and by motivating such persons to contribute to the growth and profitability of the Company, the Company's Board of Directors and stockholders approved an ESPP and reserved 1,000,000 shares of our common stock for issuance effective as of May 15, 2011. The ESPP continues in effect for ten (10) years from its effective date unless terminated earlier by the Company. The ESPP consists of six-month offering periods during which employees may enroll in the plan.  The purchase price on each purchase date shall not be less than eighty-five percent (85%) of the lesser of (a) the fair market value of a share of stock on the offering date of the offering period or (b) the fair market value of a share of stock on the purchase date.  During the three months ended March 31, 2013, no shares were granted under ESPP.

Restricted Stock Units

On May 23, 2012, the Board of Directors of the Company approved, based on recommendations of the Compensation Committee, a grant of 98,363 RSUs to non-employee directors based on a fair market value of $2.82 per share which represents the closing price of the Company's common stock on the Nasdaq Global Select Market ("Nasdaq") on May 23, 2012.  These RSUs vest upon the first anniversary of the grant date.

During the first quarter of 2013, the Company's Compensation Committee approved the grant of RSUs to certain key executives. The RSUs granted to these executives included (i) 249,750 time-based RSUs that vest over a required service period of three years, and (ii)  399,750 performance-based RSUs contingent upon a required service period of three years and as well as the Company's achievement of specified annual performance targets for fiscal year 2013. We measured the grant-date fair value of the performance-based RSUs based upon the closing price of the Company's common stock on the Nasdaq as of the grant date. We expense the fair value of the performance-based RSUs that are probable of being earned based on our forecasted annual performance  for fiscal year 2013.

At March 31, 2013, there was $1.7 million of unrecognized compensation cost related to RSUs which is expected to be recognized over a weighted average period of 2.02 years.

Stock Repurchase Program

On April 27, 2005, our Board of Directors authorized the repurchase of up to 2,000,000 outstanding shares of our common stock. As of March 31, 2013 the maximum number of shares remaining that can be repurchased under this program was 1,807,402. The Company does not intend to repurchase shares without a further approval from its Board of Directors.

Repurchase of Shares

On February 19, 2013, the Company entered into an agreement with Joshua Pickus, the Company's President and Chief Executive Officer, pursuant to which Mr. Pickus sold directly to the Company on that day an aggregate 1,000,000 shares of its common stock acquired by him in a same-day exercise of fully vested options which were due to expire at the end of their seven-year term on April 6, 2013.  Under the agreement, the purchase price per share was established as an amount equal to the lesser of (a) the closing price of the Company's common stock in regular trading hours on the day of the sale as reported by Nasdaq less 5%, or (b) the thirty-day simple moving average price of the Company's common stock on the day of the sale. This formula produced a purchase price per share of $4.114, less the aggregate strike price due on exercise of the options underlying the repurchased shares of $2.32 per share, which then resulted in a net cash outlay by the Company to acquire the shares of approximately $1.8 million (or $1.794 per share). The agreement was approved by the independent members of the Company's Board of Directors. The share repurchase amounted to $4.1 million and is classified under treasury stock within stockholders' equity of the condensed consolidated balance sheets.
