The Plan authorizes for issuance 350,000 shares of the Company's common stock. &amp;#160;The Plan requires that options be granted at an exercise price equal to at least 100% of the fair market value of the common stock on the date of the grant. Such options are generally not exercisable until three years from the date of issuance and generally require continuous employment during the period prior to exercise. &amp;#160;The options will expire in no more than ten years after the date of grant. The stock options, stock appreciation rights, restricted shares, and long-term performance unit awards for certain employees are generally subject to vesting requirements and are subject to forfeiture if vesting and other contractual provision requirements are not met. &amp;#160;Effective January 1, 2000, the Omnibus Stock Ownership and Long-Term Incentive Plan for employees was amended and restated to include non-employee directors. The Company did not grant stock options during the three months or six months ended June 30, 2013 and there were no options outstanding at June 30, 2013.&lt;/div&gt;&lt;div style="margin-top: 3pt; margin-bottom: 3pt;"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; margin-top: 3pt; font-family: Times New Roman; margin-bottom: 3pt; font-size: 10pt; font-weight: bold;"&gt;Restricted Shares&lt;/div&gt;&lt;div style="margin-top: 3pt; margin-bottom: 3pt;"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; margin-top: 3pt; font-family: Times New Roman; margin-bottom: 3pt; font-size: 10pt;"&gt;The restricted shares are accounted for using the fair market value of the Company's common stock on the date the restricted shares were awarded. The restricted shares issued to certain officers are subject to a vesting period, whereby, the restrictions on the shares lapse on the third year anniversary of the date the restricted shares were awarded. &amp;#160;Compensation expense for these shares is accrued over the three year period. &amp;#160;The restricted share issued to non-employee directors are not subject to a vesting period, and compensation expense is recognized at the date the shares are granted.&lt;/div&gt;&lt;div style="margin-top: 3pt; margin-bottom: 3pt;"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: left; margin-top: 3pt; font-family: Times New Roman; margin-bottom: 3pt; font-size: 10pt;"&gt;The Company has granted awards of non-vested shares to certain officers and vested shares to non-employee directors under the above-described incentive plans: 12,470 shares and 11,925 shares of unvested restricted stock to executive officers, and 5,712 shares and 5,632 shares of vested restricted stock to non-employee directors on February 21, 2013 and February 16, 2012, respectively. &amp;#160;Compensation expense for these non-vested shares amounted to $36,000 and $35,000, net of forfeiture, for the three months ended June 30, 2013 and 2012, and $75,000 and $69,000 for the six months ended June 30, 2013 and 2012, respectively. &amp;#160;Compensation expense for the non-employee director shares is recognized at the date the shares are granted and during the three months ended June 30, 2013 and 2012, there was none. &amp;#160;For the six month periods ended June 30, 2013 and 2012, the compensation expense was $68,000. &amp;#160;As of June 30, 2013, there was $231,000 of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the plans. &amp;#160;This type of deferred compensation cost is recognized over a period of 3 years.&lt;/div&gt;&lt;div style="margin-top: 3pt;
