Share-Based Compensation
SHARE-BASED COMPENSATION
 
The Company has two stock option plans in existence: the 2012 Omnibus Incentive Plan (the “Omnibus Plan”) and the Innovate 2015 Stock Incentive Plan (the “Private Innovate Plan”). In addition, the Company assumed 1,014,173 options in accordance with the terms of the RDD Merger Agreement. The shares reserved for issuance under the Omnibus Plan automatically increase on the first day of each calendar year beginning in 2019 and ending in 2022 by an amount equal to the lesser of (i) five percent of the number of shares of common stock outstanding as of December 31st of the immediately preceding calendar year or (ii) such lesser number of shares of common stock as determined by the Board (the “Evergreen Provision”). On January 1, 2020 and 2019, the number of shares of common stock available under the Omnibus Plan automatically increased by 1,973,883 and 1,304,441 shares pursuant to the Evergreen Provision, respectively. Additionally, on June 30, 2020, stockholders approved an amendment to the Omnibus Plan to increase the number of shares of common stock available under the Omnibus Plan to 20,794,492 shares.

The terms of the option agreements are determined by the Board. The Company’s stock options vest based on the terms in the stock option agreements and typically vest over a period of three or four years. These stock options typically have a maximum term of ten years.
