The Company has five equity compensation plans: the 2009 Amended Stock Plan, the 2010 Equity Incentive Plan, the 2012 Equity Incentive Plan, 2014 Equity Incentive Plan and the 2018 Stock Incentive Plan (the “Plans”). Originally, the Company was able to grant up to 27,410 and 54,820 shares of Common Stock as both incentive stock options (“ISOs”) and nonqualified stock options (“NQs”) under the 2010 Equity Incentive Plan and the 2012 Equity Incentive Plan, respectively. In 2013, the Company’s stockholders approved an increase to 63,957 shares authorized for issuance under the 2010 Equity Incentive Plan. In 2014, the Board of Directors of the Company (the “Board”) approved an increase to 67,520 shares authorized for issuance under the 2010 Equity Incentive Plan.

In 2014, the Company’s stockholders approved the 2014 Equity Incentive Plan pursuant to which the Company may grant up to 91,367 shares as ISOs, NQs and restricted stock units (“RSUs”), subject to increases as hereafter described (the “Plan Limit”). In addition, on January 1, 2015 and each January 1 thereafter prior to the termination of the 2014 Equity Incentive Plan, pursuant to the terms of the 2014 Equity Incentive Plan, the Plan Limit was and shall be increased by the lesser of (x) 4% of the number of shares of Common Stock outstanding as of the immediately preceding December 31 and (y) such lesser number as the Board of Directors may determine in its discretion. On January 1, 2016, 2017, 2018 and 2019 the Plan Limit was increased to 152,366 shares, 210,203 shares, 271,941 shares and 323,529 shares, respectively. In March 2019, the Plan was amended and restated which removed the annual increase component and was limited to 826,292 shares.

In 2018, the Company’s stockholders approved the 2018 Stock Incentive Plan pursuant to which the Company may grant up to 558,071 shares as Stock Options, (ii) Stock Appreciation Rights, (iii) Restricted Stock, (iv) Deferred Stock, (v) Stock Reload Options and/or (vi) Other Stock-Based Awards.

Pursuant to the terms of the Plans, ISOs have a term of ten years from the date of grant or such shorter term as may be provided in the option agreement. Unless specified otherwise in an individual option agreement, ISOs generally vest over a four year term and NQs generally vest over a one to five year terms. Unless terminated by the Board, the Plans shall continue to remain effective for a term of ten years or until such time as no further awards may be granted and all awards granted under the Plans are no longer outstanding.
