Stock Options and Restricted Stock Units

On May 23, 2014, the shareholders of the Company approved the 2014 Equity Incentive Plan (the “2014 Plan”). Under the terms of the 2014 Plan, the Company is authorized to issue incentive awards for common stock up to 200,000 shares to employees and other personnel. On June 10, 2016, the shareholders of the Company approved an additional 200,000 awards to be issued under the 2014 Plan, bringing the total number of shares to be awarded to 400,000. The awards may be in the form of incentive stock options, nonqualified stock options, restricted stock, restricted stock units and performance awards. The 2014 Plan is effective through March 31, 2024. As of December 31, 2019, there are 23,500 shares which remain to be granted under the 2014 Plan.

On August 9, 2010, the shareholders of the Company approved the 2010 Equity Incentive Plan (the “2010 Plan”). Under the terms of the 2010 Plan, 150,000 shares of the Company’s common stock were authorized for the issuance of stock options and restricted stock. The 2010 Plan also provides for an automatic annual increase in the number of authorized shares of common stock issuable beginning in 2011 equal to the lesser of (a) 2% of shares outstanding on the last day of the immediately preceding year, (b) 50,000 shares, or (c) such lesser number of shares as the Company’s board of directors shall determine, provided, however, in no event shall the maximum number of shares that may be issued under the Plan pursuant to stock awards be greater than 15% of the aggregate shares outstanding on the last day of the immediately preceding year. With the automatic increases, there were 220,416 authorized shares of common stock on January 1, 2012. On January 20, 2012, the Company’s Board of Directors approved an increase in the number of shares authorized under the 2010 Plan from 220,416 to 420,416. This increase was ratified by the shareholders of the Company on June 29, 2012. On December 31, 2018, there were no shares remaining for awards to be issued under the 2010 Plan.
