PROFUSA, INC. AND SUBSIDIARY
NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED) Note 9 — Stock Option Plan In 2010, the Company adopted the 2010 Equity Incentive Plan (the “Plan”) under which 2,000,000shares of the Company’s common stock have been initially reserved for issuance to employees, directors and consultants. The number of reserved shares has been increased over the years and currently equals 4,636,454shares. Options granted under the Plan may be either incentive stock options (“ISO”) or nonqualified stock options (“NSO”). ISOs may be granted only to Company employees, including officers and directors who are also employees. NSOs may be granted to Company employees, consultants and advisors. A person who owns (or is deemed to own) stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company will not be granted an ISO unless the exercise price of such option is at least one hundred ten percent (110%) of the Fair Market Value on the date of grant and the option is not exercisable after the expiration of five years from the date of grant. Options granted generally vest over four years. Activity under the Plan is set forth below:
