Form of non-employee director restricted stock unit issuance agreement under 2004 Equity Incentive Plan (for grants commencing in 2020)

A.Optionee is to render valuable services to the Company as a non-employee Director and this Stock Option Agreement (this “Agreement”) is executed pursuant to, and is intended to carry out the purposes of, the Plan in connection with the Company’s grant of an option to Optionee in his or her capacity as a non-employee Director.

B.All capitalized terms used in this Agreement shall have the meaning assigned to them herein and in the attached Appendix A. Capitalized terms not defined herein or in the attached Appendix A shall have the meanings assigned to them in the Plan.

NOW, THEREFORE, the Company hereby grants this option to Optionee upon the following terms and conditions:

1.Grant of Option. The Company hereby grants to Optionee, as of the Grant Date indicated below, an option to purchase the Option Shares under the Plan. The number of Option Shares purchasable under the option, the applicable vesting schedule for the option, the Exercise Price per Share and the remaining terms and conditions governing the option shall be as set forth in this Agreement.

2.Option Term. The term of the option shall commence on the Grant Date and continue to be in effect until the close of business on the last business day prior to the

Expiration Date (whether such day is a business day, holiday or weekend), unless sooner terminated in accordance with Paragraph 5 or 6 below.

3.Limited Transferability. Prior to actual receipt of the Shares upon exercise of this option, Optionee may not transfer or assign any interest in the option or the underlying Shares, except that the option may be assigned in whole or in part during Optionee’s lifetime to one or more members of Optionee’s Immediate Family, provided such assignment constitutes a gratuitous transfer by Optionee for which no consideration is directly or indirectly received. The assigned portion may only be exercised by the person who acquires a proprietary interest in the option pursuant to the assignment. The terms applicable to the assigned portion shall be the same as those in effect for the option immediately prior to such assignment and shall be set forth in such documents to be executed by Optionee and the assignee as the Company may deem appropriate. The option may also may also be transferred to a designated beneficiary or by will or the laws of inheritance upon Participant’s death.

4.Dates of Exercise. The option shall become exercisable for the Option Shares in a series of installments over Optionee’s period of Continuous Service in accordance with the Vesting Schedule set forth in Paragraph 1 above. As the option becomes exercisable for such installments, those installments shall accumulate, and the option shall remain exercisable for the accumulated installments until (i) the close of business on the last business day prior to the Expiration Date or (ii) the sooner termination of the option term under Paragraph 5 or 6 below.

5.Cessation of Service. The option term specified in Paragraph 2 above shall terminate (and the option shall cease to be outstanding) prior to the Expiration Date should any of the following provisions become applicable:

(a)Except as otherwise expressly provided in subparagraphs (b) through (d) of this Paragraph 5, should Optionee cease to remain in Continuous Service for any reason while the option is outstanding, then Optionee shall have until the close of business on the last business day prior to the expiration of the three-(3) year period measured from the date of such cessation of Continuous Service during which to exercise the option for any or all of the Option Shares for which the option is at the time of such cessation of Continuous Service vested and exercisable, but in no event shall the option be exercisable at any time after the close of business on the last business day prior to the Expiration Date.

(b)Should Optionee’s Continuous Service terminate by reason of his or her death while the option is outstanding, then the Option Shares shall fully vest and the option may be exercised for any or all of the Option Shares at the time subject to the option by the person or persons to whom the option is transferred during Optionee’s lifetime pursuant to a permitted transfer under Paragraph 3 above or, in the absence of any such transfer, by: (i) the designated beneficiary or beneficiaries under any beneficiary designation in effect for the option at the time of Optionee’s death, (ii) the personal representative of Optionee’s estate, or (iii) the person or persons to whom the option is transferred pursuant to Optionee’s will or the laws of inheritance following Optionee’s death, as the case may be. Any right to exercise the option shall lapse, and the option shall cease to be outstanding, upon the close of business on the last

business day prior to the earlier of (i) the expiration of the three-(3) year period measured from the date of Optionee’s death or (ii) the Expiration Date. Upon the expiration of such limited exercise period, the option shall terminate and cease to be outstanding for any exercisable Option Shares for which the option has not otherwise been exercised.

(c)The applicable period of post-service exercisability in effect pursuant to the foregoing provisions of this Paragraph 5 shall automatically be extended by an additional period of time equal in duration to any interval within such post-service exercise period during which the exercise of the option or the immediate sale of the Option Shares acquired under the option cannot be effected in compliance with applicable federal, state and foreign securities laws, but in no event shall such an extension result in the continuation of the option beyond the close of business on the last business day prior to the Expiration Date.

(d)Should Optionee’s Continuous Service terminate for Cause, or should Optionee engage in any other conduct, while in such service or following cessation of Continuous Service, that is materially detrimental to the business or affairs of the Company (or any Related Entity), as determined in the sole discretion of the Administrator, then the option shall terminate immediately and cease to be outstanding.

(e)For purposes of the foregoing provisions of this Paragraph 5, Optionee shall not be deemed to cease Continuous Service if Optionee continues to serve the Company as a Director Emeritus immediately following his or her cessation of service as a Board member without an intervening break in Continuous Service.

(f)During the limited period of post-service exercisability provided under this Paragraph 5, the option may not be exercised in the aggregate for more than the number of Option Shares for which the option is at the time vested and exercisable. Except to the extent (if any) specifically authorized by the Administrator pursuant to an express written agreement with Optionee, the option shall not vest or become exercisable for any additional Option Shares, whether pursuant to the exercise/vesting schedule set forth in Paragraph 1 above or the special vesting acceleration provisions of Paragraph 6 below, following Optionee’s cessation of Continuous Service. Upon the expiration of such limited exercise period or (if earlier) upon the close of business on the last business day prior to the Expiration Date, the option shall terminate and cease to be outstanding for any exercisable Option Shares for which the option has not otherwise been exercised.

6.Change in Control.

(a)Should Optionee remain in Continuous Service until the effective date of a Change in Control, then the option, to the extent outstanding at the time but not otherwise fully exercisable, shall automatically accelerate so that the option shall, immediately prior to the effective date of the Change in Control, become exercisable for all of the Option Shares at the time subject to the option, and may be exercised for any or all of those Option Shares as fully vested shares of Common Stock.

(b)Immediately following the consummation of a Change in Control transaction, the option shall terminate and cease to be outstanding, except to the extent assumed by the successor corporation (or parent thereof) or otherwise continued in effect pursuant to the terms of the Change in Control transaction.

(c)If the option is assumed in connection with a Change in Control or otherwise continued in effect, then the option shall be appropriately adjusted, immediately after such Change in Control, to apply to the number and class of securities into which the shares of Common Stock subject to the option would have been converted in consummation of such Change in Control had those shares actually been outstanding at the time. Appropriate adjustments shall also be made to the Exercise Price, provided the aggregate Exercise Price shall remain the same. To the extent the actual holders of the Company’s outstanding Common Stock receive cash consideration for their Common Stock in consummation of the Change in Control, the successor corporation may, in connection with the assumption or continuation of the option but subject to the Administrator’s approval, substitute one or more shares of its own common stock with a fair market value equivalent to the cash consideration paid per share of Common Stock in such Change in Control, provided such common stock is readily tradable on an established U.S. securities exchange or market.

(d)This Agreement shall not in any way affect the right of the Company to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets.

7.Adjustment in Option Shares. Should any change be made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares, spin-off transaction, extraordinary dividend or distribution or other change affecting the outstanding Common Stock as a class without the Company’s receipt of consideration, or should the value of the outstanding shares of Common Stock be substantially reduced as a result of a spin-off transaction or an extraordinary dividend or distribution, or should there occur any merger, consolidation or other reorganization, then equitable and proportional adjustments shall be made by the Administrator to (i) the total number and/or class of securities subject to the option and (ii) the Exercise Price. The adjustments shall be made in such manner as the Administrator deems appropriate in order to reflect such change and thereby prevent the dilution or enlargement of benefits hereunder, and those adjustments shall be final, binding and conclusive upon Optionee and any other person or persons having or claiming an interest in the option. In the event of any Change in Control transaction, the adjustment provisions of Paragraph 6(c) above shall be controlling.

8.Stockholder Rights. The holder of the option shall not have any stockholder rights including voting, dividend, or liquidation rights with respect to the Option Shares until such person shall have exercised the option, paid the Exercise Price and become a holder of record of the purchased Shares.

9.Manner of Exercising Option.

(a)In order to exercise the option with respect to all or any portion of the Option Shares for which the option is at the time vested and exercisable, Optionee (or any other person or persons exercising the option) must take the following actions:

(i)Execute and deliver to the Company a Notice of Exercise as to the Option Shares for which the option is exercised or comply with such other procedures as the Company may establish for notifying the Company, directly or through a brokerage firm authorized by the Company to effect option exercises, of the exercise of the option for one or more Option Shares. The applicable Notice of Exercise may be obtained upon request through stockplanservices@gilead.com.

(ii)Pay the aggregate Exercise Price for the purchased Shares in one or more of the following forms:

(A)cash or check made payable to the Company; or

(B)through a special sale and remittance procedure pursuant to which Optionee (or any other person or persons exercising the option) shall concurrently provide irrevocable instructions (i) to a brokerage firm (reasonably satisfactory to the Company for purposes of administering such procedure in accordance with the Company’s pre-clearance/pre-notification policies) to effect the immediate sale of all or a sufficient portion of the purchased Shares so that such brokerage firm can remit to the Company, on the settlement date, sufficient funds out of the resulting sale proceeds to cover the aggregate Exercise Price payable for all the purchased Shares plus any Withholding Taxes and (ii) to the Company to deliver the purchased Shares directly to such brokerage firm on such settlement date.

Except to the extent the sale and remittance procedure is utilized in connection with the option exercise, payment of the Exercise Price must accompany the Notice of Exercise (or other notification procedure) delivered to the Company in connection with the option exercise.

(iii)Furnish to the Company appropriate documentation that the person or persons exercising the option (if other than Optionee) have the right to exercise the option.

(iv)Make appropriate arrangements with the Company (or Related Entity employing or retaining Optionee) for the satisfaction of any Withholding Taxes.

(b)On or as promptly as practicable after the Exercise Date, the Company shall issue to or on behalf of Optionee (or any other person or persons exercising the

option) a certificate for the purchased Option Shares (either in paper or electronic form), with the appropriate legends affixed thereto.

(c)In no event may the option be exercised for any fractional shares.

10.Compliance with Laws and Regulations.

(a)The exercise of the option and the issuance of the Option Shares upon such exercise shall be subject to compliance by the Company and Optionee with all Applicable Laws relating thereto, as determined by counsel for the Company.

(b)The inability of the Company to obtain approval from any regulatory body having authority deemed by the Company to be necessary to the lawful issuance and sale of any Common Stock pursuant to the option shall relieve the Company of any liability with respect to the non-issuance or sale of the Common Stock as to which such approval shall not have been obtained. The Company, however, shall use its reasonable best efforts to obtain all such approvals.

(c)Optionee may be subject to insider trading restrictions and/or market abuse laws based on the exchange on which the shares of Common Stock are listed and in applicable jurisdictions including the United States and Optionee’s country or his or her broker’s country, if different, which may affect Optionee’s ability to accept, acquire, sell or otherwise dispose of shares of Common Stock, rights to shares of Common Stock (e.g., options) or rights linked to the value of shares of Common Stock during such times as Optionee is considered to have “inside information” regarding the Company (as defined by the laws in applicable jurisdictions). Local insider trading laws and regulations may prohibit the cancellation or amendment of orders Optionee placed before he or she possessed inside information. Furthermore, Optionee could be prohibited from (i) disclosing the inside information to any third party, which may include fellow employees and (ii) “tipping” third parties or causing them otherwise to buy or sell securities. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable insider trading policy of the Company. Optionee acknowledges that it is Optionee’s responsibility to comply with any applicable restrictions and Optionee should speak with his or her personal legal advisor on this matter.

11.Successors and Assigns. Except to the extent otherwise provided in Paragraphs 3 and 6 above, the provisions of this Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns and Optionee, Optionee’s assigns, the legal representatives, heirs and legatees of Optionee’s estate and, designated beneficiaries.

12.Notices. Any notice required to be given or delivered to the Company under the terms of this Agreement shall be in writing and addressed to the Company at its principal corporate offices. Any notice required to be given or delivered to Optionee shall be in writing and addressed to Optionee at the most current address then indicated for Optionee on the Company’s records or shall be delivered electronically to Optionee through the Company’s electronic mail system or through an on-line brokerage firm authorized by the Company to effect

option exercises through the internet. All notices shall be deemed effective upon personal delivery or electronic delivery as specified above or upon deposit in the U.S. or local country mail, postage prepaid and properly addressed to the party to be notified.

13.Construction. This Agreement and the option evidenced hereby are made and granted pursuant to the Plan and are in all respects limited by and subject to the terms of the Plan. In the event of any conflict between the provisions of this Agreement and the terms of the Plan, the terms of the Plan shall be controlling. All decisions of the Administrator with respect to any question or issue arising under the Plan or this Agreement shall be conclusive and binding on all persons having an interest in the option.

15.Severability. The provisions of this Agreement are severable and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable.

16.Waiver. Optionee acknowledges that a waiver by the Company of breach of any provision of this Agreement shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach of this Agreement.

17.Excess Shares. If the Option Shares covered by this Agreement exceed, as of the Grant Date, the number of shares of Common Stock which may without stockholder approval be issued under the Plan, then the option shall be void with respect to those excess shares, unless stockholder approval of an amendment sufficiently increasing the number of shares of Common Stock issuable under the Plan is obtained in accordance with the provisions of the Plan. In no event shall the option be exercisable with respect to any of the excess Option Shares unless and until such stockholder approval is obtained.

18.No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Optionee’s participation in the Plan or Optionee’s acquisition or sale of the Option Shares. Optionee is hereby advised to consult with his or her personal tax, legal and financial advisors regarding his or her participation in the Plan before taking any action related to the Plan.

19.No Impairment of Rights. This Agreement shall not in any way be construed or interpreted so as to affect adversely or otherwise impair the right of the Company or its stockholders to remove Optionee from the Board at any time in accordance with the provisions of Applicable Law.

In no event shall the option be exercised in the absence of such acceptance. An exercise of any portion of the Shares subject to this Option shall be deemed to be an acceptance by Optionee of the terms and conditions of this Agreement.

24.Imposition of Other Requirements. The Company reserves the right to impose other requirements on Optionee’s participation in the Plan, on the option and on any shares of Common Stock acquired under the Plan, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require Optionee to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

(a)the Plan is established voluntarily by the Company, it is discretionary in nature, and it may be modified, amended, suspended or terminated by the Company at any time, to the extent permitted by the Plan;

(b)the option is voluntary and occasional and does not create any contractual or other right to receive future grants of options, or benefits in lieu of options, even if options have been granted in the past;

(k)unless otherwise provided in the Plan or by the Company in its discretion, the option and the benefits evidenced by this Agreement do not create any entitlement to have the option or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the shares of the Company; and

(l)neither the Company nor any Related Entity shall be liable for any exchange rate fluctuation between Optionee’s local currency and the United States Dollar that may affect the value of the option or of any amounts due to Optionee pursuant to the exercise of the option or the subsequent sale of any Option Shares acquired upon exercise.

3.Data Privacy.

(a)Data Privacy Consent. By accepting this Agreement either electronically through the electronic acceptance procedure established by the Company or through a written acceptance, Optionee is declaring that he or she agrees with the data processing practices described herein and consents to the collection, processing and use of Personal Data (as defined below) by the Company and the transfer of Personal Data to the recipients mentioned herein, including recipients located in countries which do not adduce an adequate level of protection from a European (or other) data protection law perspective, for the purposes described herein.

(b)Declaration of Consent. Optionee understands that he or she needs to review the following information about the processing of his or her personal data by or on behalf of the Company and/or any Related Entity as described in the Agreement and any other Plan materials (the “Personal Data”) and declare his or her consent. As regards the processing of Optionee’s Personal Data in connection with the Plan and this Agreement, Optionee understands that the Company is the controller of his or her Personal Data.

(c)Data Processing and Legal Basis. The Company collects, uses and otherwise processes Personal Data about Optionee for the purposes of allocating shares of Common Stock and implementing, administering and managing the Plan. Optionee understands that this Personal Data may include, without limitation, his or her name, home address and telephone number, email address, date of birth, social insurance number, passport number or other identification number (e.g., resident registration number), remuneration, nationality, job title, any shares of stock or directorships held in the Company, details of all options or any other entitlement to shares of stock or equivalent benefits awarded, cancelled, exercised, vested,

unvested or outstanding in Optionee’s favor. The legal basis for the processing of Optionee’s Personal Data, where required, will be his or her consent.

(d)Stock Plan Administration Service Providers. Optionee understands that the Company transfers his or her Personal Data, or parts thereof, to E*TRADE Financial Services, Inc. (and its affiliated companies), an independent service provider based in the United States which assists the Company with the implementation, administration and management of the Plan. In the future, the Company may select a different service provider and share Optionee’s Personal Data with such different service provider that serves the Company in a similar manner. Optionee understands and acknowledges that the Company’s service provider will open an account for him or her to receive and trade shares of Common Stock acquired under the Plan and that he or she will be asked to agree on separate terms and data processing practices with the service provider, which is a condition of Optionee’s ability to participate in the Plan.

(e)International Data Transfers. Optionee understands that the Company and, as of the date hereof, any third parties assisting in the implementation, administration and management of the Plan, such as E*TRADE Financial Services, Inc., are based in the United States. Optionee understands and acknowledges that his or her country may have enacted data privacy laws that are different from the laws of the United States. For example, the European Commission has issued only a limited adequacy finding with respect to the United States that applies solely if and to the extent that companies self-certify and remain self-certified under the EU/U.S. Privacy Shield program. The Company currently participates in the EU/U.S. Privacy Shield Program, though third parties implementing, administering, and managing the Plan may not. The Company’s legal basis for the transfer of Optionee’s Personal Data is his or her consent.

(f)Data Retention. Optionee understands that the Company will use his or her Personal Data only as long as is necessary to implement, administer and manage his or her participation in the Plan, or to comply with legal or regulatory obligations, including under tax and securities laws. In the latter case, Optionee understands and acknowledges that the Company’s legal basis for the processing of his or her Personal Data would be compliance with the relevant laws or regulations. When the Company no longer needs Optionee’s Personal Data for any of the above purposes, Optionee understands the Company will remove it from its systems.

(g)Voluntariness and Consequences of Denial/Withdrawal of Consent. Optionee understands that his or her participation in the Plan and his or her consent is purely voluntary. Optionee may deny or later withdraw his or her consent at any time, with future effect and for any or no reason. If Optionee denies or later withdraws his or her consent, the Company can no longer offer Optionee participation in the Plan or offer other equity awards to Optionee or administer or maintain such awards and Optionee would no longer be able to participate in the Plan.
