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 Global Select Market less five percent (5%), or (b) the thirty-day simple moving average price of the Company's common stock on the day of the sale.  The agreement was approved by the independent members of the Company's Board of Directors. This share repurchase resulted in a total net cash payment of $1.8 million that will be accounted for as a reduction in the Company's stockholders' equity.
