5. Stock-Based Compensation

Under the Company’s equity incentive plans, directors and eligible employees may be granted incentive or non-statutory stock options and/or restricted stock units, or awarded non-vested stock. As of June 30, 2013, the only options granted by the Company were non-statutory stock options to selected Bank officers and non-employee directors at exercise prices equal to the fair market value of a share of the Company’s common stock on the date of grant. Such options have a maximum ten-year term and vest in 20% annual increments (subject to early termination in certain events) except certain options granted to the Chief Executive Officer of the Company in 2005 and 2008. If such options expire or terminate without having been exercised, any shares not purchased will again be available for future grants or awards. There were no options granted during the first six months of 2013 or during 2012.

Option compensation expense was zero for the three months ended June 30, 2013, and $194,000 for the three months ended June 30, 2012. For the six months ended June 30, option compensation expense totaled $129,000 for 2013 and $387,000 for 2012. Stock-based compensation is recognized ratably over the requisite service period for all awards. All unrecognized stock-based compensation expense was fully recognized as of June 30, 2013.

No stock options were exercised in the first six months of 2013 compared to 39,784 shares issued on the exercise of stock options in the first six months 2012. Cash received totaled $647,000 and the aggregate intrinsic value totaled $34,000 from the exercise of stock options during the first six months ended June 30, 2012. The table below summarizes stock option activity for the periods indicated:
