The Company granted stock options to certain employees under two plans. The 1996 Stock Option Plan was adopted in 1996 (“1996 Plan”) and had options granted under it through May 29, 2006. In 2006, the Board of Directors approved and the shareholders ratified the 2006 Stock Incentive Plan (“2006 Plan”).

As determined by the members of the Compensation Committee, the Company generally grants options under the 2006 Plan at the estimated fair value at the date of grant, based upon all information available to it at the time.

The Company recognizes compensation costs only for those shares expected to vest on a straight-line basis over the requisite service period of the awards. Generally such options vest over periods of six months to two years. The fair values of option awards granted in 2012 and 2011 were estimated using the Black-Sholes option pricing model under the following assumptions:

2006 Stock Incentive Plan

The 2006 Plan became effective May 18, 2006, and expires May 17, 2016. The 2006 Plan provides for the granting of equity awards to key employees, including officers and directors. The maximum number of shares for which equity awards may be granted under the 2006 Plan is 1,950,000. Options under the 2006 Plan expire no later than ten years from the date of grant or when employment ceases, whichever comes first, and vest over periods determined by the Board of Directors. The average vesting period for options granted to employees under the 2006 Plan in the years ended December 31, 2012 and 2011, were twelve months and nineteen months, respectively. The exercise price of each option equals the quoted market price of the Company’s stock on the date of grant.

1996 Stock Option Plan

The 1996 Plan provided for the granting of options to purchase shares of our common stock to key employees, including officers and directors. The maximum number of shares for which options could be granted under the 1996 Plan was 3,075,000. Options expire no later than ten years from the date of grant or when employment ceases, whichever comes first, and vest over periods determined by the Board of Directors. There were 360,000 and 411,000 unexpired exercisable options remaining from the 1996 Plan at December 31, 2012 and 2011, respectively.

The status of the options issued under the foregoing option plans as of December 31, 2012, and changes during the years ended December 31, 2012 and 2011, were as follows:
