EXHIBIT A

TERMS AND CONDITIONS OF STOCK OPTION GRANT

1. Grant of Option. The Company hereby grants to the Participant named in the Notice of Grant (the “Participant”) an option (the “Option”) to purchase the number of Shares, as set forth in the Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the “Exercise Price”), subject to all of the terms and conditions in this Agreement. The Option granted pursuant to this Agreement is intended to qualify as an employment inducement award under Nasdaq Listing Rule 5635(c)(4) (the “Inducement Listing Rule”) and is an inducement material to the Participant’s entering into employment with the Company in accordance with the Inducement Listing Rule.

2. Vesting Schedule; Termination of Service Provider Status. Except as provided in Section 3, the Option awarded by this Agreement will vest in accordance with the vesting provisions set forth in the Notice of Grant. Shares scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest in the Participant in accordance with any of the provisions of this Agreement, unless the Participant will have been continuously a Service Provider from the Date of Grant until the date such vesting occurs.

(a) Effect of Termination. Any portion of the Option that has not vested will be forfeited if the Participant ceases to be a Service Provider and the Participant will have no further right, title or interest in such forfeited portion of the Option, the Shares subject to the Option, or any consideration in respect of the Option; provided, however, that if the Company has a contingent contractual obligation to provide for accelerated vesting of the Option after the Participant ceases to be a Service Provider, the unvested portion of the Option subject to potential acceleration shall remain outstanding until the maximum contractual time for determining whether such contingency will occur (but no later than the Term/Expiration Date), and will terminate at such time if the contingency has not then occurred. If after termination the Participant does not exercise the vested portion of the Option within the time specified in the Notice of Grant, the Option will terminate.

(b) Leaves of Absence/Transfer Between Locations. Unless the Administrator provides otherwise, vesting of the Option will be suspended during any unpaid leave of absence. The Participant will not cease to be an Employee in the case of (i) any leave of absence approved by the Company or (ii) transfers between locations of the Company or between the Company, its Parent, or any Subsidiary.

(c) Change in Time Commitment. In the event the Participant’s regular level of time commitment in the performance of the Participant’s services for the Company and any affiliates is reduced (for example, and without limitation, if the Participant is an Employee of the Company and the Participant has a change in status from a full-time Employee to a part-time Employee or takes an extended leave of absence) after the Date of Grant, then, subject to Applicable Law, the Administrator may, in its sole discretion and without the consent of the Participant, (i) make a corresponding reduction in the number of Shares subject to the Option that are scheduled to vest or become payable after the date of such change in time commitment, and (ii) in lieu of or in combination with such a reduction, extend the vesting or payment schedule applicable to the Option. For the avoidance of doubt, in the event of any reduction under clause (i) of the preceding sentence, the Participant shall have no rights with respect to the number of Shares as to which the Option was so reduced.

3. Administrator Discretion. The Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser portion of the balance, of the unvested Option at any time. If so accelerated, such Option will be considered as having vested as of the date specified by the Administrator.

4. Exercise of Option.

(a) Right to Exercise. This Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during such term only in accordance with the terms of this Agreement.

(b) Method of Exercise. This Option is exercisable by delivery of an exercise notice, in the form attached as Exhibit B (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which will state the election to exercise the Option, the number of Shares in respect of which the Option

is being exercised (the “Exercised Shares”), and as a condition to the exercise of an Option, the Company may require the Participant to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required. The Exercise Notice will be completed by the Participant and delivered to the Company. The Exercise Notice will be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares together with any applicable tax withholding. This Option will be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price.

5. Method of Payment. Payment of the aggregate Exercise Price will be by any of the following, or a combination thereof, at the election of the Participant:

(a) cash;

(b) check;

(c) consideration received by the Company under a formal cashless exercise program adopted by the Company applicable to the Option; or

(d) surrender of other Shares which have a fair market value on the date of surrender equal to the aggregate Exercise Price of the Exercised Shares, provided that accepting such Shares, in the sole discretion of the Administrator, will not result in any adverse accounting consequences to the Company.

6. Adjustments; Dissolution or Liquidation; Change in Control.

(a) Adjustments. 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 the Option, will adjust the number, class, and Exercise Price of Shares covered by the Option.

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will notify the Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it previously has not been exercised, the Option will terminate immediately prior to the consummation of such proposed action.

(c) Change in Control. In the event of a Change in Control, the outstanding Option will be treated as the Administrator determines, including, without limitation, that (i) the Option may be assumed, or a substantially equivalent Option will be substituted, by the acquiring or succeeding corporation (or an affiliate thereof) with appropriate adjustments as to the number and kind of shares and exercise price; (ii) upon written notice to the Participant, that the Option will terminate upon or immediately prior to the consummation of such Change in Control; (iii) the outstanding Option will vest and become exercisable, in whole or in part prior to or upon consummation of such Change in Control, and, to the extent the Administrator determines, terminate upon or immediately prior to the effectiveness of such merger or Change in Control; (iv) (A) the termination of the Option in exchange for an amount of cash and/or property, if any, equal to the amount that would have been attained upon the exercise of the Option as of the date of the occurrence of the transaction (and, for the avoidance of doubt, if as of the date of the occurrence of the transaction the Administrator determines in good faith that no amount would have been attained upon the exercise of the Option, then the Option may be terminated by the Company without payment), or (B) the replacement of the Option with other rights or property selected by the Administrator in its sole discretion; or (v) any combination of the foregoing.

In the event that the successor corporation does not assume or substitute for the Option, the Participant will fully vest in and have the right to exercise the outstanding Option, including Shares as to which the Option would not otherwise be vested or exercisable. In addition, if the Option is not assumed or substituted in the event of a Change in Control, the Administrator will notify the Participant in writing or electronically that the Option will be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option will terminate upon the expiration of such period.

For the purposes of this subsection (c), the Option will be considered assumed if, following the Change in Control, the Option confers the right to purchase or receive, for each Share subject to the Option immediately prior to the Change in Control, the consideration (whether stock, cash, or other securities or property) received in the Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Option to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the Change in Control.

7. Tax Obligations.

(a) Withholding of Taxes. Notwithstanding any contrary provision of this Agreement, no certificate representing the Shares will be issued to the Participant, unless and until satisfactory arrangements (as determined by the Administrator) will have been made by the Participant with respect to the payment of income, employment, social insurance, payroll and other taxes which the Company determines must be withheld with respect to such Shares. To the extent determined appropriate by the Company in its discretion, it will have the right (but not the obligation) to satisfy any tax withholding obligations by reducing the number of Shares otherwise deliverable to the Participant. If the Participant fails to make satisfactory arrangements for the payment of any required tax withholding obligations hereunder at the time of the Option exercise, the Participant acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver the Shares if such withholding amounts are not delivered at the time of exercise.

(b) Code Section 409A. Under Code Section 409A, an option that vests after December 31, 2004 (or that vested on or prior to such date but which was materially modified after October 3, 2004) that was granted with a per share exercise price that is determined by the Internal Revenue Service (the “IRS”) to be less than the fair market value of a share on the date of grant (a “Discount Option”) may be considered “deferred compensation.” A Discount Option may result in (i) income recognition by the Participant prior to the exercise of the option, (ii) an additional 20% federal income tax, and (iii) potential penalty and interest charges. The Discount Option may also result in additional state income, penalty and interest charges to the Participant. The Participant acknowledges that the Company cannot and has not guaranteed that the IRS will agree that the Exercise Price per Share of this Option equals or exceeds the Fair Market Value of a Share on the Date of Grant in a later examination. The Participant agrees that if the IRS determines that the Option was granted with an Exercise Price per Share that was less than the Fair Market Value of a Share on the Date of Grant, the Participant will be solely responsible for the Participant’s costs related to such a determination.

8. Rights as Stockholder. Neither the Participant nor any person claiming under or through the Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to the Participant. After such issuance, recordation and delivery, the Participant will have all the rights of a stockholder of the Company with respect to voting such Shares and receipt of dividends and distributions on such Shares.

9. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND WILL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

10. Address for Notices. Any notice to be given to the Company under the terms of this Agreement will be addressed to the Company at CareDx, Inc., ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇., ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, or at such other address as the Company may hereafter designate in writing.

11. Non-Transferability of Option. This Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of the Participant only by the Participant.

12. Binding Agreement. Subject to the limitation on the transferability of this grant contained herein, this Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto.

13. Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion, that the listing, registration, qualification or rule compliance of the Shares upon any securities exchange or under any state, federal or foreign law, the tax code and related regulations or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the purchase by, or issuance of Shares to, the Participant (or his or her estate) hereunder, such purchase or issuance will not occur unless and until such listing, registration, qualification, rule compliance, consent or approval will have been completed, effected or obtained free of any conditions not acceptable to the Company. The Company will make all reasonable efforts to meet the requirements of any such state, federal or foreign law or securities exchange and to obtain any such consent or approval of any such governmental authority or securities exchange. Assuming such compliance, for income tax purposes the Exercised Shares will be considered transferred to the Participant on the date the Option is exercised with respect to such Exercised Shares. The inability of the Company to obtain authority from any regulatory body having jurisdiction or to complete or comply with the requirements of any registration or other qualification of the Shares under any state, federal or foreign law or under the rules and regulations of the Securities and Exchange Commission, the stock exchange on which Shares of the same class are then listed, or any other governmental or regulatory body, which authority, registration, qualification or rule compliance is deemed by the Company’s counsel to be necessary or advisable for the issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority, registration, qualification or rule compliance will not have been obtained.

14. Administrator Authority. The Administrator will have the power to interpret this Agreement and to adopt rules for the administration, interpretation and application of this Agreement and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Shares subject to the Option have vested). All actions taken and all interpretations and determinations made by the Administrator in good faith will be final and binding upon the Participant, the Company and all other interested persons. No member of the Administrator will be personally liable for any action, determination or interpretation made in good faith with respect to this Agreement.

15. Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to the Option by electronic means. The Participant hereby consents to receive such documents by electronic delivery and agrees to the administration of the Option through any on-line or electronic system established and maintained by the Company or a third party designated by the Company.

16. Captions. Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

17. Agreement Severable. In the event that any provision in this Agreement will be held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not be construed to have any effect on, the remaining provisions of this Agreement.

18. Modifications to the Agreement. This Agreement constitutes the entire understanding of the parties on the subjects covered. The Participant expressly warrants that he or she is not accepting this Agreement in reliance on any promises, representations, or inducements other than those contained herein. Modifications to this Agreement can be made only in an express written contract executed by a duly authorized officer of the Company. Notwithstanding anything to the contrary in this Agreement, the Company reserves the right to revise this Agreement as it deems necessary or advisable, in its sole discretion and without the consent of the Participant, to comply with Code Section 409A or to otherwise avoid imposition of any additional tax or income recognition under Section 409A of the Code in connection to this Option.

19. Amendment, Suspension or Termination. By accepting this Option, the Participant expressly warrants that the Participant has received this Option pursuant to this Agreement, and has received, read and understood this Agreement.

20. Governing Law. This Agreement will be governed by the laws of California, without giving effect to the conflict of law principles thereof. For purposes of litigating any dispute that arises under this Option or this Agreement, the parties hereby submit to and consent to the jurisdiction of the State of California, and agree that such litigation will be conducted in the courts of San Mateo County, California, or the federal courts for the United States for the Northern District of California, and no other courts, where this Option is made and/or to be performed.

(j) “Disability” means total and permanent disability as defined in Section 22(e)(3) of the Code, provided that the Administrator in its discretion may determine whether a permanent and total disability exists in accordance with uniform and non-discriminatory standards adopted by the Administrator from time to time.

(k) “Employee” means any person, including officers and Directors, employed by the Company or any Parent or Subsidiary of the Company. Neither service as a Director nor payment of a director’s fee by the Company will be sufficient to constitute “employment” by the Company. The Company shall determine in good faith and in the exercise of its discretion whether an individual has become or has ceased to be an Employee and the effective date of such individual’s employment or termination of employment, as the case may be. For purposes of an individual’s rights, if any, under this Agreement as of the time of the Company’s determination, all such determinations by the Company shall be final, binding and conclusive, notwithstanding that the Company or any court of law or governmental agency subsequently makes a contrary determination.

(i) If the Common Stock is listed on any established stock exchange or a national market system, including without limitation the New York Stock Exchange, the Nasdaq Global Select Market, the Nasdaq Global Market or the Nasdaq Capital Market of The Nasdaq Stock Market LLC, its Fair Market Value will be the closing sales price for such stock (or the closing bid, if no sales were reported) as quoted on such exchange or system on the day of determination, as reported in The Wall Street Journal or such other source as the Administrator deems reliable;

(ii) If the Common Stock is regularly quoted by a recognized securities dealer but selling prices are not reported, the Fair Market Value of a Share will be the mean between the high bid and low asked prices for the Common Stock on the date of determination (or, if no bids and asks were reported on that date, as applicable, on the last trading date such bids and asks were reported), as reported in The Wall Street Journal or such other source as the Administrator deems reliable; or

(iii) In the absence of an established market for the Common Stock, the Fair Market Value will be determined in good faith by the Administrator.
