5. Stock Option Plan

In September 2011, the Company obtained shareholder approval of the 2011 Incentive Compensation Plan (the “Plan”), which replaced the 2007 Stock Award Plan (the “2007 Plan”). The 2007 Plan, however, will continue to govern awards previously granted under it. The Plan share reserve includes the sum of 6.0 million shares of the Company’s common stock, plus (i) any shares of its common stock which have been reserved but not issued pursuant to any awards granted under the 2007 Plan, and (ii) the number of shares subject to outstanding awards under the 2007 Plan that expire or otherwise terminate without having been exercised in full, or are forfeited to or repurchased by the Company.

A summary of the Company’s stock option activity related to common stock for the six months ended June 30, 2013 and 2012 is as follows:

	2013					2012
	Shares			Weighted- Average Exercise Price		Shares			Weighted- Average Exercise Price
	(In thousands except exercise price)

As of June 30, 2013, there was $6.1 million of total unrecognized compensation cost, net of estimated forfeitures, related to stock options granted under the Company’s stock incentive plans, which is expected to be recognized over a weighted average period of 3.49 years.
