Prior to joining Heartflow, he held senior finance positions at Intuitive Surgical and eBay after beginning his career working for PricewaterhouseCoopers. Mr. Radford after receiving his Bachelor of Business Administration from Ohio University.

Mr. Radford has no family relationship with any of the executive officers or directors of the Company. There are no arrangements or understandings between Mr. Radford and any other person pursuant to which he was elected as an officer of the Company.

Mr. Radford entered into an employment offer letter with the Company (the “Offer Letter”). Under the Offer Letter, Mr. Radford’s annual base salary is $464,000 and his annual target bonus opportunity will be 40% of his annual base salary. Upon commencement of his employment on April 19, 2021 (the “Commencement Date”), Mr. Radford was granted an option to purchase up to 27,600 shares of common stock of the Company (the “Stock Options”). The Stock Options will vest as to 25% of the underlying shares on the first anniversary of the Commencement Date and as to an additional 2.0833% of the shares at the end of each successive month following the first anniversary of the Commencement Date until the fourth anniversary of such date. The stock options will have an exercise price per share equal to the closing market price of the Company’s common stock on the Commencement Date. Additionally, Mr. Radford was also granted 17,100 restricted stock units (“RSUs”). The RSUs will vest as to 25% of the underlying shares on or about the first anniversary of the Commencement Date and as to an additional 6.25% of the shares every three-month anniversary of such date thereafter. The RSUs will have an exercise price per share equal to the closing market price of the Company’s common stock on the Commencement Date.

Under the Company’s Change in Control and Severance Policy (the “Severance Policy”), if the Company terminates Mr. Radford other than for “cause,” death or “disability” or he resigns for “good reason”, in each case, during the period beginning upon a “change in control”, such terms as defined in the Severance Policy, and ending 24 months following the change in control, such period referred to as the change in control period, he will be eligible to receive the following severance benefits (less applicable tax withholdings): (i) a lump sum cash amount equal to 12 months of his then-current annual base salary (or if he resigns for good reason based on a material reduction in base salary, then his annual base salary in effect immediately prior to such reduction) or if greater, at the level in effect immediately before the change in control, (ii) a lump sum cash amount equal to 100% of his then-current target annual bonus opportunity, (iii) 100% of his then outstanding and unvested equity awards will become fully vested and exercisable, if applicable, and any applicable performance goals will be deemed achieved at 100% of target levels, and (iv) payment or reimbursement of continued health coverage for him and his dependents under COBRA for a period of up to 12 months, or a taxable lump sum payment in lieu of such payment or reimbursement, as applicable. Further, under the Severance Policy, if Mr. Radford is terminated other than for cause, death or disability outside the change in control period, he will be eligible to receive the following severance benefits (less applicable tax withholding): (i) a lump sum cash amount equal to 9 months of his then-current annual base salary, (ii) a lump sum cash amount equal to a pro rata portion of his then-current target annual bonus opportunity and (iii) payment or reimbursement of continued health coverage for him and his dependents for a period of up to 9 months, or a taxable lump sum payment in lieu of such payment or reimbursement, as applicable. To receive any severance benefits under the Severance Policy, Mr. Radford must sign and not revoke our standard separation agreement and release of claims within the timeframe set forth in the Severance Policy. If any of the payments provided for under the Severance Policy or otherwise payable to Mr. Radford would constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code and would be subject to the related excise tax under Section 4999 of the Internal Revenue Code, then he will be entitled to receive either full payment of benefits or such lesser amount which would result in no portion of the benefits being subject to the excise tax, whichever results in the greater amount of after-
