CareDx, Inc. Outside Director Compensation Policy, effective April 1, 2023

CareDx, Inc. (the “Company”) believes that the granting of equity and cash compensation to its members of the Board of Directors (the “Board,” and members of the Board, the “Directors”) represents an effective tool to attract, retain and reward Directors who are not employees of the Company (the “Outside Directors”). This Outside Director Compensation Policy (the “Policy”) is intended to formalize the Company’s policy regarding cash compensation and grants of equity to its Outside Directors. Unless otherwise defined herein, capitalized terms used in this Policy will have the meaning given such term in the Company’s 2014 Equity Incentive Plan (the “Plan”). Each Outside Director will be solely responsible for any tax obligations incurred by such Outside Director as a result of the equity and cash payments such Outside Director receives under this Policy.

There are no per meeting attendance fees for attending Board, Audit & Finance Committee, Compensation & Human Capital Committee, Governance & Nominating Committee and/or Science & Technology Committee meetings.

Retainers (other than chairman retainers) will be paid quarterly in arrears on a prorated basis.

The retainers will be paid in shares of Company common stock (“Shares”) and/or in cash. Each Director can elect the ratio of Shares to cash for the payment of these retainers by notifying the Company in writing (with email notification being sufficient). Such elections will be effective commencing in the first quarter after the quarter in which they are made. For purposes of determining the payment of the retainer, Shares will be valued at the average closing price in the quarter for which the retainer is paid.

Outside Directors will be entitled to receive all types of Awards (except Incentive Stock Options) under the Plan (or the applicable equity plan in place at the time of grant), including discretionary Awards not covered under this Policy. All grants of Awards to Outside Directors pursuant to Section 2 of this Policy will be automatic and nondiscretionary, except as otherwise provided herein, and will be made in accordance with the following provisions:

(1)No Discretion. No person will have any discretion to select which Outside Directors will be granted any Awards under this Policy or to determine the number of Shares to be covered by such Awards.

(2)Appointment Awards. Subject to Section 11 of the Plan, upon an Outside Director’s appointment to the Board, such Outside Director automatically will be granted (i) a Nonstatutory Stock Option to purchase Shares having a grant date fair value of $100,000, rounded down to the nearest whole share (the “NSO Appointment Award”), and (ii) Restricted Stock Units having a grant date fair value of $100,000, rounded down to the nearest whole share (the “RSU Appointment Award”). Subject to Section 5 below and Section 14 of the Plan, each NSO Appointment Award will vest in thirty-six (36) equal, monthly installments beginning with the first monthly anniversary after the grant date, and each RSU Appointment Award will vest in three (3), equal, annual installments beginning with the first annual anniversary after the grant date. Each NSO Appointment Award and RSU Appointment Award will vest fully upon a Change in Control (as defined in the Plan), in each case, provided that the Outside Director continues to serve as a Service Provider through the applicable vesting date or Change in Control, as applicable.

(c)    Annual Awards. Subject to Section 11 of the Plan, on the first business day after each Annual Meeting of the Company’s stockholders (the “Annual Meeting”) beginning with the 2019 Annual Meeting, each Outside Director automatically will be granted (i) a Nonstatutory Stock Option to purchase Shares having a grant date fair value of $150,000, rounded down to the nearest whole share (the “Annual NSO Award”), and (ii) Restricted Stock Units having a grant date fair value of $150,000, rounded down to the nearest whole share (the “Annual RSU Award”). Subject to Section 5 below and Section 14 of the Plan, each Annual NSO Award will vest in twelve (12) equal, monthly installments beginning with the first monthly anniversary after the grant date, and each Annual RSU Award will vest in one (1) installment on the one year anniversary of the grant date. Each Annual NSO Award and Annual RSU Award will vest fully upon a Change in Control (as defined in the Plan), in each case, provided that the Outside Director continues to serve as a Service Provider through the applicable vesting date or Change in Control, as applicable.

(d)    Terms Applicable to all Options Granted Under this Policy. The per Share exercise price for all other Options granted under this Outside Director Compensation Policy will be one hundred percent (100%) of the Fair Market Value on the grant date.

Each Outside Director’s reasonable, customary and documented travel expenses to Board meetings will be reimbursed by the Company.

All provisions of the Plan not inconsistent with this Policy will apply to Awards granted to Outside Directors.

In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company or other change in the corporate structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under this Policy, will adjust the number of Shares issuable pursuant to Awards granted under this Policy.

The Board in its discretion may change and otherwise revise the terms of Awards granted under this Policy, including, without limitation, the number of Shares subject thereto, for Awards of the same or different type granted on or after the date the Board determines to make any such change or revision.
