The above table excludes founder holdbacks related to business combinations. A variable number of shares will be issued upon vesting to settle a fixed monetary amount of $5.3 million which are contingent upon continued employment with the Company for two years. One-half of the founder holdbacks will vest after one year of continued employment, with the remainder vesting monthly during the second year. The share price will be determined based on the Company’s average stock price 5 days prior to each vesting date.
