Explanation of Responses:
(1)  RSUs vest 25% per year over a four year period, commencing on the first anniversary of the grant date. RSUs convert into common stock on the vest date on a one-for-one basis. 25 % of the shares have been released and a portion of the shares were held back to cover the statutory tax withholding requirements. The net shares were deposited into the holders account.
(2)  25% of the shares subject to the option vest on the six-month anniversary measured from February 10, 2023, and 1/24th of the total number of shares vest in eighteen (18) successive and equal monthly installments thereafter, subject to Reporting Person's continuous service to the Issuer through each such vesting date.
(3)  Each RSU granted represents a contingent right to receive one share of Intuitive Surgical common stock. The grant vests 25% on the first anniversary of the date of grant and annually thereafter, over a four year period.
(4)  Constitute restricted stock units ("RSUs"). Each RSU represents a contingent right to receive one share of Issuer common stock upon vesting. 50% of the RSUs shall vest on each anniversary of February 10, 2023, subject to Reporting Person's continuous service to the Issuer through each such vesting date.
