Stock Incentive Plan
On October 31, 2014, the Board approved the Company’s 2014 Omnibus Incentive Plan (the “2014 Plan”). The 2014 Plan initially reserved 3,200,000 shares for future grants. In October 2018, the Company increased the share reserve under the 2014 Plan to equal 10% of the number of issued and outstanding shares of common stock of the Company on an evergreen basis. In August 2020, the Company approved Amendment No. 2 to the 2014 Plan, which increased the share reserve by an additional 7,876,835 shares over the 10% of the number of issued and outstanding shares of common stock and removed certain restrictions on the number of shares of common stock and the amount of cash-based awards up to which participants of the 2014 Plan can receive in a calendar year. The 2014 Plan authorizes the issuance of awards including stock options, stock appreciation rights, restricted stock, stock units and performance units to employees, directors, and consultants of the Company. As of December 31, 2021, the shares available for future grant under the 2014 Plan are as follows:
Shares Available for Grant
Available as of December 31, 2020 12,790,775

Forfeited 1,091,250 
Granted (18,755,000)
Available as of December 31, 2021 14,132,929 
Stock Options
Options granted under the 2014 Plan expire no later than ten years from the date of grant. Options granted under the 2014 Plan may be either incentive or non-qualified stock options. For incentive and non-qualified stock option grants, the option price shall be at least 100% of the fair value on the date of grants, as determined by the Company’s Board of Directors. If at any time the Company grants an option, and the optionee directly or by attribution owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, the option price shall be at least 110% of the fair value and shall not be exercisable more than five years after the date of grant.
Options granted under the 2014 Plan may be immediately exercisable if permitted in the specific grant approved by the Board of Directors and, if exercised early may be subject to repurchase provisions. The shares issued generally vest over a period of one to four years from the date of grant.
