 3. Stock Subject to the Plan. 
 (a) Subject to the provisions of Section 10 below, the maximum aggregate
number of Shares which may be issued pursuant to all Awards (including, without limitation, Restricted Stock, Restricted Stock Units, Performance Shares, Options, SARs, Dividend Equivalent Rights, and Phantom Shares) is 60,400,0002 Shares, plus the additional 23,588,284 Shares previously authorized for issuance in the aggregate under the Gilead Sciences, Inc. 1991 Stock Option Plan and
the Gilead Sciences, Inc. 1995 Non-Employee Directors’ Stock Option Plan which were not required to be issued with respect to options outstanding under those plans on May 25, 2004. Notwithstanding the foregoing, no more than 5,000,000 of
such Shares may be issued pursuant to all Awards of Restricted Stock, Restricted Stock Units, Performance Shares, SARs, and Phantom Shares, in total.3 The Shares to be issued pursuant to Awards may be authorized, but unissued, or reacquired Common Stock. Performance Units that by their terms may only be settled in cash shall not reduce the maximum aggregate number of shares that may be
issued under the Plan. 
 (b) Any Shares covered by an Award (or portion of an Award) which is forfeited, canceled or expires
(whether voluntarily or involuntarily) shall be deemed not to have been issued for purposes of determining the maximum aggregate number of Shares which may be issued under the Plan. Shares that actually have been issued under the Plan pursuant to an
Award shall not be returned to the Plan and shall not become available for future issuance under the Plan, except that if unvested Shares are forfeited, or repurchased by the Company at the lower of their original purchase price or their Fair Market
Value at the time of repurchase, such Shares shall become available for future grant under the Plan. Should the exercise price of an option under the Plan be paid with shares of Common Stock, then the authorized reserve of Common Stock under the
Plan shall be reduced by the gross number of shares for which that option is exercised, and not by the net number of shares issued under the exercised stock option. Upon the exercise of any stock appreciation right under the Plan, the share reserve
shall be reduced by the gross number of shares as to which such right is exercised, and not by the net number of shares actually issued by the Company upon such exercise. If shares of Common Stock otherwise issuable under the Plan are withheld by
the Company in satisfaction of the withholding taxes incurred in connection with the issuance, exercise, vesting or settlement of an Award, then the number of shares of Common Stock available for issuance under the Plan shall be reduced by the gross
number of Shares issuable at that time under such Award, calculated in each instance prior to any such share withholding. 
 4.
Administration of the Plan. 
 (a) Plan Administrator: 
 (i) Administration with Respect to Directors and Officers. With respect to grants of Awards to Directors or Employees who are also
Officers or Directors of the Company, the Plan shall be administered by (A) the Board or (B) a Committee designated by the Board, which Committee shall be constituted in such a manner as to satisfy the Applicable Laws and to permit such
grants and related transactions under the Plan to be exempt from Section 16(b) of the Exchange Act in accordance with Rule 16b-3. Once appointed, such Committee shall continue to serve in its designated capacity until otherwise directed by the
Board. With respect to the grant of an Award to a Director who is not an Employee and which is not a scheduled Award under predetermined rules established by the Board or Committee, such grant shall be made only by a Committee (or subcommittee of
the Committee) which is comprised solely of two or more Non-Employee Directors, as this term is defined in Rule 16b-3, none of whom are the recipient of the Award.

	 Maximum number of Shares consists of 3,600,000 Shares authorized coincident with the adoption of the 2004 Equity
Incentive Plan at the 2004 annual stockholders meeting, another 3,600,000 Shares due to the share adjustment for the two-for-one stock split effective September 3, 2004, an additional 10,000,000 Shares authorized and approved at the 2005 annual

	 The 5,000,000 limit includes Performance Units to the extent
these Awards are settled in Shares. The Company has never declared nor paid a cash dividend and does not intend to grant any dividend equivalent rights in the foreseeable future; however, if a dividend equivalent right were to be granted in the
future, the Company would consider the dividend equivalent right subject to the 5,000,000 limit.

 (ii) Administration With Respect to Consultants and Other Employees. With respect
to grants of Awards to Employees or Consultants who are neither Directors nor Officers of the Company, the Plan shall be administered by (A) the Board or (B) a Committee designated by the Board, which Committee shall be constituted in such
a manner as to satisfy the Applicable Laws. Once appointed, such Committee shall continue to serve in its designated capacity until otherwise directed by the Board. The Board may authorize one or more Officers of the Company or any Parent to grant
such Awards, subject to such terms and conditions as the Board may impose; provided, however, that any delegation of such authority shall in all events be subject to the limitations and restrictions of Applicable Laws, including any required
limitation on the maximum of Shares for which Awards may be made by such Officer or Officers. 
 (iii) Administration With
Respect to Covered Employees. Notwithstanding the foregoing, grants of Awards to any Covered Employee intended to qualify as Performance-Based Compensation shall be made only by a Committee (or subcommittee of a Committee) which is comprised
solely of two or more Directors eligible to serve on a committee making Awards qualifying as Performance-Based Compensation. In the case of such Awards granted to Covered Employees, references to the “Administrator” or to a
“Committee” shall be deemed to be references to such Committee or subcommittee. 
 (b) Powers of the
Administrator. Subject to Applicable Laws and the provisions of the Plan (including any other powers given to the Administrator hereunder), and except as otherwise provided by the Board, the Administrator shall have the authority, in its
discretion:

hereunder;

 (iv) to approve forms of Award Agreements for use under the Plan; 
 (v) to determine the terms and conditions of any Award granted hereunder; 
 (vi) to amend the terms of any outstanding Award granted under the Plan, provided that (A) any amendment that would adversely affect
the Grantee’s rights under an outstanding Award shall not be made without the Grantee’s written consent, (B) the reduction of the exercise price of any Option or Stock Appreciation Right awarded under the Plan shall be subject to
stockholder approval as provided in Section 7(b), and (C) canceling an Option or Stock Appreciation Right at a time when its exercise price exceeds the Fair Market Value of the underlying Shares, in exchange for another Option, Stock
Appreciation Right, Restricted Stock or other Award shall be subject to stockholder approval as provided in Section 7(b), unless the cancellation and exchange occurs in connection with a Change in Control as provided in Section 11 or
pursuant to an adjustment effected in accordance with Section 10; 
 (vii) to construe and interpret the terms of the
Plan and Awards, including without limitation, any notice of award or Award Agreement, granted pursuant to the Plan; 
 (viii)
to establish additional terms, conditions, rules or procedures to accommodate the rules or laws of applicable non-U.S. jurisdictions and to afford Grantees favorable treatment under such rules or laws; provided, however, that no Award shall be
granted under any such additional terms, conditions, rules or procedures with terms or conditions which are inconsistent with the provisions of the Plan; and 
  

 -7- 

 (ix) to take such other action, not inconsistent with the terms of the Plan, as the

Company is delegated shall be defended and indemnified by the Company to the extent permitted by law on an after-tax basis against all reasonable expenses (including attorneys’ fees), actually and necessarily incurred in connection with the
defense of any claim, investigation, action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or any Award
granted hereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by the Company) or paid by them in satisfaction of a judgment in any such claim, investigation, action, suit or proceeding, except in
relation to matters as to which it shall be adjudged in such claim, investigation, action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct; provided, however, that within 30 days after the
institution of such claim, investigation, action, suit or proceeding, such person shall offer to the Company, in writing, the opportunity at the Company’s expense to handle and defend the same. 
 5. Eligibility. Awards other than Incentive Stock Options may be granted to Employees, Directors and Consultants. Incentive Stock Options may be
granted only to Employees of the Company or a Parent or a Subsidiary of the Company. An Employee, Director or Consultant who has been granted an Award may, if otherwise eligible, be granted additional Awards. Awards may be granted to such Employees,
Directors or Consultants who are residing in non-U.S. jurisdictions as the Administrator may determine. 
 6. Terms and Conditions of
Awards. 
 (a) Type of Awards. The Administrator is authorized under the Plan to award any type of arrangement to
an Employee, Director or Consultant that is not inconsistent with the provisions of the Plan and that by its terms involves or might involve the issuance of (i) Shares, (ii) cash or (iii) an Option, a SAR, or similar right with a
fixed or variable price related to the Fair Market Value of the Shares and with an exercise or conversion privilege related to the passage of time, the occurrence of one or more events, or the satisfaction of performance criteria or other

 (b) Designation of Award. Each Award shall be designated
in the Award Agreement. In the case of an Option, the Option shall be designated as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the
Shares for which one or more Options designated as Incentive Stock Options become first exercisable by a Grantee during any calendar year (under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, the excess number of Shares
shall be treated as subject to Nonstatutory Stock Options. For this purpose, Incentive Stock Options shall be taken into account in the order in which they were granted, except to extent otherwise provided by Applicable Law, and the Fair Market
Value of the Shares shall be determined as of the grant date of the relevant Option. 
 (c) Conditions of Award.
Subject to the terms of the Plan, the Administrator shall determine the provisions, terms, and conditions of each Award including, but not limited to, the Award vesting schedule, repurchase provisions, rights of first refusal, forfeiture provisions,

Administrator. In addition, such performance criteria may be based upon the attainment of specified levels of the Company’s performance under one or more of the measures described above relative to the performance of other entities and may also
be based on the performance of any of the Company’s business units or divisions or any Parent or Subsidiary. Each applicable performance criteria may include a minimum threshold level of performance below which no Award will be earned, levels
of performance at which specified portions of an Award will be earned and a maximum level of performance at which an Award will be fully earned. Each applicable performance criteria may be structured at the time of the Award to provide for

substitution for, outstanding awards or obligations to grant future awards in connection with the acquisition by the Company or a Related Entity of another entity, an interest in another entity or an additional interest in a Related Entity, whether
by merger, stock purchase, asset purchase or other form of transaction. 
 (e) Deferral of Award Payment. The
Administrator may establish one or more programs under the Plan to permit selected Grantees the opportunity to elect to defer receipt of the Shares or other consideration due upon the settlement of an Award, satisfaction of performance criteria, or
other event that absent the election would entitle the Grantee to payment or receipt of Shares or other consideration under an Award. The Administrator may establish the election procedures, the timing of such elections, the mechanisms for payments
of, and accrual of interest or other earnings, if any, on amounts, Shares or other consideration so deferred, and such other terms, conditions, rules and procedures that the Administrator deems advisable for the administration of any such deferral
program. Notwithstanding the foregoing, each such deferral opportunity shall be structured by the Administrator so as to comply with all applicable requirements of Code Section 409A and the Treasury Regulations thereunder. 
 (f) Separate Programs. The Administrator may establish one or more separate programs under the Plan for the purpose of issuing
particular forms of Awards to one or more classes of Grantees on such terms and conditions as determined by the Administrator from time to time. 
 (g) Individual Limitations on Awards. The maximum number of Shares with respect to which Options may be granted to any Grantee in any fiscal year of the Company shall be limited to 2,500,000 Shares. The maximum
number of Shares as to which Restricted Stock, Restricted Stock Units, Performance Shares, Performance Units, SARs, or Phantom Shares may in the aggregate be granted to any Grantee in any fiscal year of the Company shall be 400,000 Shares. For the
fiscal year in which occurs an Employee’s or Consultant’s (i) commencement of Continuous Service or (ii) promotion, an Employee or Consultant may be granted Options for up to an additional 1,000,000 Shares or Restricted Stock,
Restricted Stock Units Performance Shares, Performance Units, SARs or Phantom Shares for up to an additional 200,000 shares in the aggregate, which shall not count against the limits set forth in the preceding sentence. The foregoing limitations
shall be adjusted proportionately in connection with any change in the Company’s capitalization pursuant to Section 10, below. The value of all Awards denominated in U.S. dollars granted in any single calendar year to any Grantee shall not
exceed $7,000,000. For 

  

 -9- 

 
this purpose, the value of an Award denominated in U.S. dollars shall be determined on the date of grant without regard to any conditions imposed on the
Award. To the extent required by Section 162(m) of the Code or the regulations thereunder, in applying the foregoing limitations with respect to a Grantee, if any Awards are canceled, the canceled Awards shall continue to count against the
maximum number of Shares with respect to which Awards may be granted to the Grantee. For this purpose, the repricing of the exercise price of an Option or SAR if such repricing is approved by the stockholders of the Company, shall be treated as the
cancellation of the existing Option or SAR and the grant of a new Option or SAR. If the vesting or receipt of Shares under the Award is deferred to a later date, any amount (whether denominated in Shares or U.S. dollars) paid in addition to the
original number of Shares subject to the Award (or the original dollar amount for an Award denominated in U.S. dollars) will not be treated as an increase in the number of Shares (or dollar amount) subject to the Award if the additional amount is
based either on a reasonable rate of interest or on one or more predetermined actual investments such that the amount payable by the Company at the later date will be based on the actual rate of return of a specific investment (including any
decrease as well as any increase in the value of an investment). 
 (h) Early Exercise. The Award Agreement may, but
need not, include a provision whereby the Grantee may elect at any time while an Employee, Director or Consultant to exercise any part or all of the Award prior to full vesting of the Award. Any unvested Shares received pursuant to such exercise may
be subject to a repurchase right in favor of the Company or a Related Entity or to any other restriction the Administrator determines to be appropriate. 
 (i) Term of Award. The term of each Award shall be the term stated in the Award Agreement, provided, however, that the term of an Award shall be no more than ten years from the date of grant thereof. However,
in the case of an Incentive Stock Option granted to a Grantee who, at the time the Option is granted, owns stock representing more than 10% of the voting power of all classes of stock of the Company or any Parent or Subsidiary of the Company, the
term of the Incentive Stock Option shall be five years from the date of grant thereof or such shorter term as may be provided in the Award Agreement. 
 (j) Transferability of Awards. Incentive Stock Options may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution
and may be exercised, during the lifetime of the Grantee, only by the Grantee. Other Awards shall be transferable by will and by the laws of descent and distribution, and during the lifetime of the Grantee, such Awards shall be transferable, by gift
or pursuant to a domestic relations order, to members of the Grantee’s Immediate Family to the extent and in the manner determined by the Administrator. Notwithstanding the foregoing, the Grantee may designate a beneficiary of the
Grantee’s Award in the event of the Grantee’s death on a beneficiary designation form provided by the Administrator. 
 (k) Time of Granting Awards. The date of grant of an Award shall for all purposes be the date on which the Administrator makes the determination to grant such Award, or such later date as is determined by the Administrator.

 7. Award Exercise or Purchase Price; Consideration and Taxes. 
 (a) Exercise or Purchase Price. The exercise or purchase price, if any, for an Award shall be as follows: 
 (i) In the case of an Incentive Stock Option: 
 (A) granted to an Employee who, at the time of the grant of such Incentive Stock Option owns stock representing more than 10% of the
voting power of all classes of stock of the Company or any Parent or Subsidiary of the Company, the per Share exercise price shall be not less than 110% of the Fair Market Value per Share on the date of grant; or 
 (B) granted to any Employee other than an Employee described in the preceding paragraph, the per Share exercise price shall be not less
than 100% of the Fair Market Value per Share on the date of grant. 
  

 -10- 

 (ii) In the case of a Nonstatutory Stock Option, the per Share exercise price shall be
not less than 100% of the Fair Market Value per Share on the date of grant. 
 (iii) In the case of a SAR, the exercise price
or the base amount on which the stock appreciation is calculated shall be not less than 100% of the Fair Market Value per Share on the date of grant. 
 (iv) In the case of other Awards, the cash consideration (if any) payable for such Award or the underlying Shares shall be determined by the Administrator. 
 (v) Notwithstanding the foregoing provisions of this Section 7(a), in the case of an Award issued pursuant to Section 6(d),
above, the exercise or purchase price for the Award shall be determined in accordance with the provisions of the relevant instrument evidencing the agreement to issue such Award. 
 (b) No Authority to Reprice. Without the consent of stockholders of the Company, no Award may be repriced, replaced, regranted
through cancellation, or modified (except as provided in Section 10) if the effect is to reduce the exercise or purchase price for the Shares underlying such Award. In addition, the replacement or substitution of one Award for another Award is
prohibited, absent stockholder consent, to the extent it has the effect of reducing the exercise or purchase price of the underlying Shares. 
 (c) Consideration. Subject to Applicable Laws, the consideration to be paid for the Shares to be issued upon exercise, vesting or settlement of an Award, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant). In addition to any other types of consideration the Administrator may determine, the Administrator is authorized to accept as consideration
for Shares issued under the Plan the following, provided that the portion of the consideration equal to the par value of the Shares must be paid in cash or other legal consideration permitted by the Delaware General Corporation Law: 
 (i) cash; 
 (ii) check; 
 (iii) services rendered, 
 (iv) surrender of Shares or delivery of a properly executed form of attestation of ownership of Shares as the Administrator may require
(including withholding of Shares otherwise deliverable upon exercise of the Award) which have a Fair Market Value on the date of surrender, attestation or withholding equal to the aggregate exercise price of the Shares as to which said Award shall
be exercised, 
 (v) with respect to Options, payment through a broker-dealer sale and remittance procedure pursuant to which
the Grantee (A) shall provide instructions (either in writing or electronically) to a Company designated brokerage firm (or, with respect to Grantees subject to Section 16 of the Securities Exchange Act, a broker 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 some or all of the purchased Shares and remit to the Company on the settlement
date sufficient funds to cover the aggregate exercise price payable for the purchased Shares and any applicable withholding taxes and (B) shall provide directives (either in writing or electronically) to the Company to deliver the certificates
for the purchased Shares directly to such brokerage firm on the settlement date in order to complete the sale transaction; or 
 (vi) any combination of the foregoing methods of payment. 
 (d) Taxes. The Company’s obligation to
deliver Shares upon the issuance, exercise, vesting or settlement of an Award under the Plan shall be subject to the satisfaction of all applicable income and employment tax withholding requirements. The Administrator may, in its discretion, provide
Grantees with the right to use shares of Common Stock in satisfaction of all or part of the Withholding Taxes to which such Grantees may become subject in connection with the issuance, exercise, vesting or settlement of those Awards. Such right may
be provided to any such holder in one or more of the following formats: 
 (i) Stock Withholding: The election to have
the Company withhold, from the Shares otherwise issuable upon the issuance, exercise, vesting or settlement of such Award, a portion of those Shares with an aggregate Fair Market Value equal to the percentage of the Withholding Taxes (not to exceed
one hundred percent (100%)) designated by such individual. The Shares so withheld shall reduce the number of shares of Common Stock authorized for issuance under the Plan. 
  

 -11- 

 (ii) Stock Delivery: The election to deliver to the Company, at the time of the
issuance, exercise, vesting or settlement of such Award, shares of Common Stock previously acquired by such individual with an aggregate Fair Market Value equal to the percentage of the Withholding Taxes (not to exceed one hundred percent
(100%)) designated by the individual. The shares of Common Stock so delivered shall neither reduce the number of shares of Common Stock authorized for issuance under the Plan nor be added to the number of shares of Common Stock authorized for
issuance under the Plan. 
 (iii) Stock Sale: The election to make an immediate open-market sale of all or a portion of
the Shares actually issued in connection with the issuance, exercise, vesting or settlement of such Award and to have a sufficient portion of the sale proceeds applied automatically on the settlement date to the satisfaction of the applicable
Withholding Taxes. 
 In addition, the Administrator may structure one or more Awards so that a portion of the Shares
otherwise issuable under those Awards shall automatically be withheld by the Company in satisfaction of the Withholding Taxes which become applicable in connection with the issuance, exercise, vesting or settlement of those Awards. 
 8. Exercise of Award. 
 (a) Procedure for Exercise; Rights as a Stockholder. 
 (i) Any Award granted hereunder shall be exercisable
at such times and under such conditions as determined by the Administrator under the terms of the Plan and specified in the Award Agreement. Notwithstanding any other provision of the Plan to the contrary, except with respect to a maximum of 5% of
the Shares authorized for issuance under Section 3(a), any Awards of Restricted Stock or Restricted Stock Units which vest on the basis of the Grantee’s Continuous Service with the Company or a Related Entity shall not provide for vesting
which is any more rapid than annual pro rata vesting over a three-year period, and any Awards of Restricted Stock, Restricted Stock Units, Performance Shares or Performance Units which provide for vesting upon the attainment of performance goals
shall provide for a performance period of at least 12 months; provided, however, that such limitations shall not apply in the event of a Change in Control or to any Grantee whose Continuous Service terminates by reason of his or her death,
disability or an involuntary termination other than for Cause. 
 (ii) An Award shall be deemed to be exercised when notice of
such exercise (either in writing or electronically) has been given to the Company or its designee in accordance with the terms of the Award by the person entitled to exercise the Award. Except to the extent the broker-dealer sale and remittance
procedure is to be utilized under Section 7(c)(iv), full payment for the Shares with respect to which the Award is exercised shall accompany such exercise notice. 
 (b) Exercise of Award Following Termination of Continuous Active Service. 
 (i) An Award may not be exercised after the termination date of such Award set forth in the Award Agreement and may be exercised following
the termination of a Grantee’s Continuous Service only to the extent provided in the Award Agreement. 
 (ii) Where the
Award Agreement permits a Grantee to exercise an Award following the termination of the Grantee’s Continuous Service for a specified period, the Award shall terminate to the extent not exercised on the last day of the specified period or the
last day of the original term of the Award, whichever occurs first. 
  

 -12- 

 (iii) Any Award designated as an Incentive Stock Option to the extent not exercised
within the time permitted by law for the exercise of Incentive Stock Options following the termination of Employee status shall convert automatically to a Nonstatutory Stock Option and thereafter shall be exercisable as such to the extent
exercisable by its terms for the period specified in the Award Agreement. 
 9. Conditions Upon Issuance of Shares. 
 (a) Shares shall not be issued pursuant to the exercise, vesting or settlement of an Award unless the exercise, vesting or settlement of
such Award and the issuance and delivery of such Shares pursuant thereto shall comply with all Applicable Laws, and shall be further subject to the approval of counsel for the Company with respect to such compliance. 
 (b) As a condition to the issuance of any Shares in connection with the exercise, vesting or settlement of an Award, the Company may
require the person holding such Award to represent and warrant at the time of such issuance that the Shares are being acquired 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 by any Applicable Laws. 
 10. Adjustments Upon Changes in Capitalization. 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 or other change affecting the outstanding Common Stock as a class without the
Company’s receipt of consideration, or should the value of 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 the maximum number and class(es) of securities subject to the Plan pursuant to Section 3(a) and the maximum number and
class(es) of securities for which Awards may be made to any person during any calendar year pursuant to Section 6(g), and the outstanding Awards (other than an Award of Restricted Stock that is outstanding at the time of the event described in
this paragraph) will be equitably and proportionally adjusted as to the number and class(es)of securities and exercise price (or other cash consideration) payable per Share subject to such outstanding Awards, including any price required to be paid
for Restricted Stock not yet outstanding at the time of the event described in this paragraph; provided, however, that the aggregate exercise price (or other cash consideration) shall remain the same. The adjustments shall be made in such manner as
the Administrator deems appropriate in order to prevent the dilution or enlargement of benefits under the Plan and the outstanding Awards thereunder, and such adjustments shall be final, binding and conclusive. In the event of a Change in Control,
however, the adjustments (if any) shall be made solely in accordance with the applicable provisions of Section 11. 
 11. Change in
Control. 
 (a) Effect of Change in Control on Awards. 
 (i) In the event of a Change in Control, the Board at its sole discretion may, to the extent permitted by applicable law, provide for the
following treatment of outstanding Options and SARs: (i) any surviving corporation shall assume any Options or SARs outstanding under the Plan or shall substitute economically equivalent awards for the Options and SARs outstanding under the
Plan, (ii) the time during which such Options or SARs may be exercised shall be accelerated so that those Awards may be exercised for fully-vested Shares and those Awards shall terminate if not exercised prior to the Change in Control, or
(iii) such Options or SARs shall continue in full force and effect. 
 (ii) Any other Award outstanding under the Plan at
the time of the Change in Control may be assumed by the surviving corporation, replaced with an economically-equivalent substitute award or otherwise continued in full force in effect. To the extent any such Award is not assumed, replaced with an
economically-equivalent substitute award or otherwise continued in effect, that Award shall vest, and the shares of Common Stock subject to that Award shall be issued as fully-vested shares, immediately prior to the effective date of the Change in
Control. 
  

 -13- 

 (iii) Any Award which is assumed in connection with a Change in Control or otherwise
continued in effect shall be adjusted immediately after the consummation of that Change in Control so as to apply to the number and class of securities into which the shares of Common Stock subject to that Award immediately prior to the Change in
Control would have been converted in consummation of such Change in Control had those shares actually been outstanding at that time, and appropriate adjustments shall also be made to the exercise price or any other consideration payable per share
thereunder, provided the aggregate exercise price or amount of such other consideration 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 outstanding Awards and subject to the approval of the Administrator prior to the Change in Control, 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 transaction, provided such common stock is readily traded on an established U.S. securities
exchange or market. 
 (iv) The Administrator may structure one or more Awards so that the Shares subject to those Awards
shall vest (or shall vest and become issuable) immediately prior to the effective date of a Change in Control, whether or not those Awards are assumed, replaced with an economically-equivalent substitute award or otherwise continued in full force
and effect 
 (b) Acceleration of Award Upon Cessation of Continuous Service In Connection With a Change in Control.
Notwithstanding any other provisions of this Plan to the contrary, if within the period beginning with the execution of the definitive agreement for a Change in Control transaction and ending with the earlier of (i) the termination of that
definitive agreement without the consummation of such Change in Control or (ii) the expiration of the Applicable Acceleration Period following the consummation of such Change in Control, either (1) the Continuous Service of an Employee or
a Consultant terminates due to an involuntary termination (not including death or Disability) without Cause (as such term is defined below) or a voluntary termination by the Grantee due to Constructive Termination (as such term is defined below) or
(2) the Continuous Service of a Director terminates, then the vesting and exercisability of all Awards held by such Grantee shall be accelerated, or any reacquisition or repurchase rights held by the Company with respect to an Award shall
lapse, as follows: 
  

	 	•	 	 With respect to Options and SARs held by a Grantee at the time of such termination, such Options and SARs shall become immediately exercisable as to all the
underlying Shares and may be exercised for any or all of those Shares as fully-vested shares until the expiration or sooner termination date of those Awards. 

  

	 	•	 	 With respect to all other Awards held by the Grantee at the time of such termination, the underlying Shares shall vest and become immediately issuable, and any
reacquisition or repurchase rights held by the Company with respect to those Shares shall lapse, as of the date of such termination. 

 (c) Definition of “Cause”. For the purposes of Section 11(b) only, “Cause” means (i) conviction of, a guilty plea with respect to, or a plea of non contendere to a charge
that a Grantee has committed a felony under the laws of the United States or of any state or a crime involving moral turpitude, including, but not limited to, fraud, theft, embezzlement or any crime that results in or is intended to result in
personal enrichment at the expense of the Company or a Related Entity; (ii) material breach of any agreement entered into between the Grantee and the Company or a Related Entity that impairs the Company’s or the Related Entity’s
interest therein; (iii) willful misconduct, significant failure of the Grantee to perform the Grantee’s duties, or gross neglect by the Grantee of the Grantee’s duties; or (iv) engagement in any activity that constitutes a
material conflict of interest with the Company or a Related Entity. 
 (d) Definition of “Constructive
Termination”. For purposes of Section 11(b) only, “Constructive Termination” means the occurrence of any of the following events or conditions: (i) (A) a change in the Grantee’s status, title, position or
responsibilities (including reporting responsibilities) which represents an adverse change from the Grantee’s status, title, position or responsibilities as in effect immediately prior to the execution of the definitive agreement for the Change
in Control transaction or at any time within the Applicable Acceleration Period after the date of a Change in Control; (B) the assignment to the Grantee of any duties or responsibilities which are inconsistent with the Grantee’s status,
title, position or responsibilities as in effect 

  

 -14- 

 
immediately prior to the execution of the definitive agreement for the Change in Control transaction or at any time within the Applicable Acceleration Period
after the Change in Control; or (C) any removal of the Grantee from or failure to reappoint or reelect the Grantee to any of the offices or positions held by the Grantee immediately prior to the execution of the definitive agreement for the
Change in Control transaction or at any time within the Applicable Acceleration Period after the date of a Change in Control, except in connection with the termination of the Grantee’s Continuous Service for Cause, as a result of the
Grantee’s Disability or death or by the Grantee other than as a result of Constructive Termination; (ii) a reduction in the Grantee’s annual base compensation or any failure to pay the Grantee any compensation or benefits to which the
Grantee is entitled within five days of the date due; (iii) the Company’s requiring the Grantee to relocate to any place outside a 50 mile radius of the location serving as Grantee’s principal work site immediately prior to the
execution of the definitive agreement for the Change in Control transaction or during the Applicable Acceleration Period after the date of a Change in Control, except for reasonably required travel on the business of the Company or a Related Entity
which is not materially greater than such travel requirements in effect during the applicable measurement period determined above; (iv) the failure by the Company to (A) continue in effect (without reduction in benefit level and/or reward
opportunities) any material compensation or employee benefit plan in which the Grantee was participating at any time within the 90-day period immediately prior to the execution of the definitive agreement for the Change in Control transaction or at
any time within the Applicable Acceleration Period after the Change in Control, unless such plan is replaced with a plan that provides substantially equivalent compensation or benefits to the Grantee, or (B) provide the Grantee with
compensation and benefits, in the aggregate, at least equal (in terms of benefit levels and/or reward opportunities) to those provided the Grantee under each other employee benefit plan, program and practice in which he or she was participating at
any time within the 90-day period immediately prior to the execution of the definitive agreement for the Change in Control transaction or at any within the Applicable Acceleration Period after the Change in Control; (v) any material breach by
the Company of any provision of an agreement between the Company and the Grantee, whether pursuant to this Plan or otherwise, other than a breach which is cured by the Company within 15 days following notice by the Grantee of such breach; or
(vi) the failure of the Company to obtain an agreement, satisfactory to the Grantee, from any successors and assigns to assume and agree to perform the obligations created under this Plan. 
 (e) Effect of Acceleration on Incentive Stock Options. Any Incentive Stock Option accelerated under this Section 11 in
connection with a Change in Control shall remain exercisable as an Incentive Stock Option under the Code only to the extent the $100,000 dollar limitation of Section 422(d) of the Code is not exceeded. To the extent such dollar limitation is
exceeded, the excess Options shall be treated as Nonstatutory Stock Options. 
 12. Effective Date and Term of Plan. The Plan shall
become effective upon its approval by the stockholders of the Company. It shall continue in effect for a term of ten years unless sooner terminated. Subject to Applicable Laws, Awards may be granted under the Plan upon its becoming effective.

 13. Amendment, Suspension or Termination of the Plan. 
 (a) The Board may at any time amend, suspend or terminate the Plan; provided, however, that no such amendment shall be made without the
approval of the Company’s stockholders to the extent such approval is required by NASD Marketplace Rule 4350(i)(1)(A), Section 422 of the Code and regulations promulgated thereunder, or any other Applicable Laws, or if such amendment would
change any of the provisions of Section 4(b)(vi) or this Section 13(a). 
 (b) No Award may be granted during any
suspension of the Plan or after termination of the Plan. 
 (c) No suspension or termination of the Plan (including
termination of the Plan under Section 12, above) shall adversely affect any rights under Awards already granted to a Grantee. 
 14.
Reservation of Shares. 
 (a) The Company, during the term of the Plan, will at all times reserve and keep available
such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 
  

 -15- 

 (b) The inability of the Company to obtain authority from any regulatory body having
jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to
which such requisite authority shall not have been obtained. 
 15. No Effect on Terms of Employment/Consulting Relationship. The Plan
shall not confer upon any Grantee any right with respect to the Grantee’s Continuous Service, nor shall it interfere in any way with his or her right or the right of the Company or any Related Entity to terminate the Grantee’s Continuous
Service at any time, with or without Cause, and with or without notice. The ability of the Company or any Related Entity to terminate the employment of a Grantee who is employed at will is in no way affected by its determination that the
Grantee’s Continuous Service has been terminated for Cause for the purposes of this Plan. 
 16. No Effect on Retirement and Other
Benefit Plans. Except as specifically provided in a retirement or other benefit plan of the Company or a Related Entity, Awards shall not be deemed compensation for purposes of computing benefits or contributions under any retirement plan of the
Company or a Related Entity, and shall not affect any benefits under any other benefit plan of any kind or any benefit plan subsequently instituted under which the availability or amount of benefits is related to level of compensation. The Plan is
not a “Pension Plan” or “Welfare Plan” under the Employee Retirement Income Security Act of 1974, as amended. 
 17.
Unfunded Obligation. Grantees shall have the status of general unsecured creditors of the Company. Any amounts payable to Grantees pursuant to the Plan shall be unfunded and unsecured obligations for all purposes, including, without
limitation, Title I of the Employee Retirement Income Security Act of 1974, as amended. Neither the Company nor any Related Entity shall be required to segregate any monies from its general funds, or to create any trusts, or establish any special
accounts with respect to such obligations. The Company shall retain at all times beneficial ownership of any investments, including trust investments, which the Company may make to fulfill its payment obligations hereunder. Any investments or the
creation or maintenance of any trust or any Grantee account shall not create or constitute a trust or fiduciary relationship between the Administrator, the Company or any Related Entity and a Grantee, or otherwise create any vested or beneficial
interest in any Grantee or the Grantee’s creditors in any assets of the Company or a Related Entity. The Grantees shall have no claim against the Company or any Related Entity for any changes in the value of any assets that may be invested or
reinvested by the Company with respect to the Plan. 
 18. Governing Law. The Plan and all agreements thereunder shall be governed by
and construed in accordance with the laws of the State of Delaware, without resort to that State’s conflict-of-law provisions. 
 19.
Section 409A Compliance. The Board reserves the right, to the extent it deems it necessary or advisable in its sole discretion, to alter or modify the Plan and any outstanding Awards under the Plan, without the consent of the Grantees,
so as to ensure that all Awards and Award Agreements provided to Grantees who are subject to U.S. income taxation either qualify for an exemption from the requirements of Section 409A of the Code or are structured in a manner that complies with
those requirements; provided, however, that neither the Company nor any Related Entity makes any representations that any Awards made under the Plan will in fact be exempt from the requirements of Section 409A of the Code or otherwise comply
with those requirements, and each Grantee shall accordingly be solely responsible for any taxes, penalties or other amounts which may become payable with respect to his or her Awards by reason of Section 409A of the Code.

	1.	HISTORY OF THE PLAN. 

 1.1 Successor Plan. The Plan is the successor plan to the Gilead Sciences, Inc. Deferred Compensation Plan, effective January 1, 2002, as amended (the “Prior Plan”). Effective as of
December 31, 2004, the Prior Plan was frozen, and no new contributions were permitted to be made to it; provided, however, that any deferrals made under the Prior Plan before January 1, 2005 will continue to be governed by
the terms and conditions of the Prior Plan as in effect on December 31, 2004. Any deferrals made under the Prior Plan after December 31, 2004 will be deemed to have been made under this Plan, and all such deferrals will accordingly be
governed by the terms and conditions of this Plan, as it may be amended from time to time. 
 1.2 Restatement. The purpose of this
October 22, 2007 restatement, as subsequently amended effective January 1, 2008, is to evidence the documentary compliance of the Plan, effective retroactive to January 1, 2005, with the applicable requirements of Section 409A of
the Internal Revenue Code, the Treasury Regulations issued under Section 409A and the interim guidance provided by the Internal Revenue and the Treasury Department prior to the publication of the final Section 409A Regulations. 

 

	2.	PURPOSE OF THE PLAN. 

 2.1 Plan Purpose. The Employer maintains the Plan, a deferred compensation plan, for the benefit of (i) a select group of management and other highly compensated employees of the Employer and (ii) the
non-employee members of the Employer’s Board of Directors. Each other Participating Employer will also maintain the Plan as a deferred compensation plan for the benefit of a select group of its management personnel and other highly compensated
employees. The Participating Employers intend that the existence of the Trust will not alter the characterization of the Plan as “unfunded” for purposes of the Employee Retirement Income Security Act of 1974, as amended
(“ERISA”), and will not be deemed to provide income to Participants under the Plan prior to the actual payment of their vested accrued benefits hereunder. The Participating Employers intend that the Plan comply with the requirements of
Section 409A of the Code and the regulations promulgated thereunder.

 Financial hardship shall not constitute an Unforeseeable Emergency under the Plan to the extent that it is, or may be,
relieved by (i) reimbursement or compensation, by insurance or otherwise, (ii) liquidation of the Participant’s assets to the extent that the liquidation of such assets would not itself cause severe financial hardship, or
(iii) cessation of deferrals under the Plan.

	5.	ELIGIBILITY; PARTICIPATION. 

 5.1 Eligibility. The Administrator (acting through an authorized committee of one or more officers or other senior executives) shall have absolute discretion in selecting the Eligible Employees who are to participate in the
Plan for each Plan Year. An Eligible Employee selected for participation for any Plan Year must, in order to participate in the Plan for that year, file a timely Deferral Election in accordance with the requirements of Section 6.1. An Eligible
Employee who is first selected for participation in the Plan after the start of a Plan Year and who has not otherwise been eligible for participation in any other non-qualified elective account balance plan subject to Code Section 409A and
maintained by one or more Affiliated Companies may file a Deferral Election for that Plan Year in accordance with the applicable requirements of Section 6.1. Until such time as the Administrator implements a new policy, any selection of new
Participants after the start of the Plan Year will be limited to the first business day of April of that Plan Year. Individuals who are selected for participation in the Plan, whether before or after 

  

 6 

 
the start of the Plan Year, shall be promptly notified by their Participating Employer of their eligibility to participate in the Plan. Eligible Directors
shall automatically be eligible to participate in the Plan during their period of service in such capacity, and their Deferral Elections shall be subject to the same requirements set forth above for Employee Participants. 
 5.2 Continuation of Participation. Every Eligible Employee who becomes a Participant may continue to file Deferral Elections under the Plan
for one or more subsequent Plan Years until the earliest of (i) his or her exclusion from the Plan upon written notice from the Administrator, (ii) his or her cessation of Eligible Employee status or (iii) the
termination of the Plan. The Administrator shall have complete discretion to exclude one or more Eligible Employees from Participant status for one or more Plan Years as the Administrator deems appropriate, including the entire period the
Participant continues in Eligible Employee status following such exclusion. However, no such exclusion authorized by the Administrator shall become effective until the first day of the first Plan Year coincident with or next following the date of
the Administrator’s determination to exclude the individual from such participation. If any Eligible Employee is excluded from Participant status for one or more Plan Years, then such individual shall not be entitled to defer any part of his or
her Compensation for those Plan Years. 
 5.3 Resumption of Participation Following Separation from Service. If a Participant
ceases to be an Eligible Employee or an Eligible Director due to a Separation from Service and thereafter returns to service with the Employer, such individual will again become a Participant as of the first day of the first Plan Year coincident
with or next following the date on which he or she resumes Eligible Employee or Eligible Director status, provided such individual files a timely a Deferral Election pursuant to Section 6.1 with respect to that Plan Year. However, a Participant
who returns to Eligible Employee or Eligible Director status after a Separation from Service of more than twenty-four (24) months during which he or she was not eligible to defer any Compensation under this Plan or any other any other
non-qualified elective account balance plan subject to Code Section 409A and maintained by one or more Affiliated Companies shall, following resumption of such service, be permitted to make a Deferral Election under Section 6.1 in
accordance with the requirements applicable to a newly-selected Participant. Notwithstanding the foregoing provisions of this Section 5.3, no returning Eligible Employee shall be eligible to participate in the Plan if the Administrator
determines to exclude such individual from participation on or before his or her resumption of service. 
 5.4 Cessation or
Resumption of Participation Following a Change in Status. If any Participant continues in the service of the Employer Group but ceases to be an Eligible Employee or Eligible Director, the individual will continue to be a Participant until the
entire amount of his or her Account balance is distributed. However, the individual will not be entitled to make any Deferral Elections with respect to Compensation earned for the period that he is not an Eligible Employee or Eligible Director. In
the event that the individual subsequently resumes Eligible Employee or Eligible Director status, he or she will again become a Participant as of the first day the first Plan Year coincident with or next following the date of his or her resumption
of Eligible Employee or Eligible Director status, provided such individual files a timely a Deferral Election pursuant to Section 6.1 with respect to that Plan Year. However, an Eligible Employee shall not be eligible to participate in the Plan
upon his or her resumption of Eligible Employee status if the Administrator determines to exclude such individual from participation on or before resumption of such status. 
  

 7 

	6.	DEFERRAL AND DISTRIBUTION ELECTIONS. 

 6.1 Deferral Elections for Employee Participants. Each Eligible Employee selected for participation shall have the right to file a Deferral
Election with respect to the Salary and/or Bonus to be earned by such Participant for service as an Eligible Employee during the Plan Year for which the Deferral Election is made. Each Deferral Election must be made by a written or electronic notice
filed with the Administrator or its designate in which the Participant shall indicate the percentage of Salary and/or Bonus to be deferred in accordance with the applicable percentage limitations set forth in Section 6.5. The notice must be
filed on or before the expiration date of the enrollment period designated by the Administrator for the Plan Year for which the Deferral Election is to be effective, but in no event shall the Administrator allow any Deferral Election to be filed
later than the last day of the calendar year immediately preceding the start of the Plan Year for which the Salary and/or Bonus subject to that election are to be earned. However, the following special rules shall be in effect for Deferral
Elections: 
 (A) The Administrator may allow a Deferral Election with respect to a Bonus which qualifies as
performance-based compensation in accordance with the standards and requirements set forth in Section 1.409A-1(e) of the Treasury Regulations to be made by a Participant after the start of the Plan Year (or other performance period) to which
that Bonus pertains but not later than by a designated date that is at least six (6) months prior to the end of that Plan Year (or any longer performance period in effect for that Bonus). 
 (B) An Eligible Employee who is first selected for participation in the Plan after the start of a Plan Year and who has not
otherwise been eligible for participation in any other non-qualified elective account balance plan subject to Code Section 409A and maintained by one or more Affiliated Companies must file his or her initial Deferral Election no later than
thirty (30) days after the date he or she is so selected. Such Deferral Election shall only be effective as follows: 
  

	 	•	 	 with respect to Salary, such election shall be effective only for the portion attributable to Employee service for the period commencing with the first day of the
first calendar month coincident with or next following the filing of such Deferral Election and ending with the close of such Plan Year, and 

  

	 	•	 	 with respect to any Bonus, such election shall be effective only for the portion thereof determined by multiplying the dollar amount of such Bonus by a fraction,
the numerator of which is the number of days remaining in the performance period applicable to that Bonus following the close of the calendar month in which the Participant’s Deferral Election as to such Bonus is filed and the denominator of
which is the total number of days in that performance period; provided, however, that in the event any such Bonus qualifies as performance-based compensation, then the provisions of Subsection 6.1(A) shall also be applicable in
determining the amount of such Bonus that may be deferred. 

  

 8 

 6.2 Deferral Elections for Eligible Directors. 
 (a) Each Eligible Director shall have the right to file a Deferral Election with respect to the Annual Retainer to be earned by
such Participant for service as an Eligible Director for the twelve (12)-month period beginning on the first day of July each Plan Year and ending on the last day of June in the succeeding Plan Year (the “Fee Period”). Each Deferral
Election must be made by a written or electronic notice filed with the Administrator or its designee in which the Participant shall indicate the percentage of the Annual Retainer for the Fee Period to be deferred in accordance with the percentage
limitations set forth in Section 6.5. The notice must be filed on or before the expiration date of the enrollment period designated by the Administrator for the Fee Period for which the Deferral Election is to be effective, but in no event
later shall the Administrator allow any Deferral Election to be filed later than the last day of the calendar year immediately preceding the Plan Year in which the Fee Period subject to that election will begin. Notwithstanding the foregoing, the
Deferral Election filed prior to the start of the 2008 Plan Year shall cover only the six (6)-month period beginning July 1, 2008 and ending December 31, 2008. 
 (b) An individual who first becomes an Eligible Director after the start of a Plan Year and who has not otherwise been eligible for
participation in any other non-qualified elective account balance plan subject to Code Section 409A and maintained by one or more Affiliated Companies must file his or her initial Deferral Election no later than thirty (30) days after the
date he or she is appointed or elected as an Eligible Director. Such Deferral Election shall only be effective with respect to the portion of the Annual Retainer attributable to Eligible Director service for the period commencing with the first day
of the first calendar month following the filing of such Deferral Election and ending on the last day of the Fee Period to which that Annual Retainer pertains. 
 6.3 Subsequent Elections. After an initial Deferral Election is made, a new Deferral Election must be made prior to each subsequent Plan Year in order for a Participant to continue participation in the
Plan for that Plan Year. Each such subsequent Deferral Election shall be effective on the first day of the Plan Year following the Plan Year in which the election is made. 
 6.4 Additional Provisions. The Deferral Election for an upcoming Plan Year shall become irrevocable upon the expiration date of the
enrollment period designated for that Plan Year, but in no event later than the last day of the immediately preceding Plan Year (or the last date on which the Deferral Election for the Plan Year may be filed under Section 6.1 or 6.2 by a
newly-eligible Participant), and no subsequent changes may be made to that Deferral Election once it becomes irrevocable. The Account maintained on behalf of each Participant will be credited with the corresponding amount of Compensation deferred by
that Participant, as and when that Compensation would have otherwise become payable in the absence of his or her Deferral Election. Under no circumstances may a Deferral Election be made retroactively. 
  

 9 

 6.5 Deferral Percentages. 
 (a) The minimum deferral per Plan Year will be determined by the Administrator. 
 (b) A Participant who is an Eligible Employee may elect to defer (less any tax withholding requirements) up to 70% of Salary and up
to 100% of Bonus in any whole multiple of 1%. 
 (c) A Participant who is an Eligible Director may elect to defer up to
100%, in any whole multiple of 1%, of the Annual Retainer for the Fee Period. 
 (d) A Participant who is an Eligible
Employee must also make satisfactory arrangements with his or her Participating Employer to assure the prompt collection of all withholding taxes applicable to the Compensation he or she elects to defer under the Plan. 
 6.6 Special Elections in 2005 regarding Deferrals. In accordance with IRS Notice 2005-1, Q&A-20, on or before March 15, 2005,

by the Administrator consistent with Section 409A of the Code and Notice 2005-1, Q&A-20. No special election under this Section 6.6 will be permitted after March 15, 2005. 
 6.7 Phantom Share Program for Directors. Eligible Directors may, as part of their Deferral Election, elect to have the Annual Retainer subject to
that election deferred in the form of fully vested Phantom Shares issued under the Gilead Sciences, Inc. 2004 Equity Incentive Plan. In the event of such election, the conversion of the deferred Annual Retainer (or the deferred portion thereof) into
such Phantom Shares shall be effected on the first day of the Fee Period to which the deferred Annual Retainer relates. At the time of distribution, the Phantom Shares shall be converted into actual shares of Gilead Sciences, Inc. common stock or
the cash value equivalent thereof, as determined by the administrator of the Gilead Sciences, Inc. 2004 Equity Incentive Plan.  
 6.8 Distribution Election. The initial Deferral Election made by a Participant under this Section 6 must include an election as to the time and form of payment of all Compensation deferred by that Participant under the
Plan, including the Compensation deferred pursuant to that initial election and all Compensation deferred pursuant to one or more subsequent Deferral Elections. The permissible distribution events or triggers are as follow:

upon the attainment of one of the following ages: 75, 70, 65, 60, 55 and 50. 
 (b) Alternatively, a Participant may
elect to receive a distribution or commence distributions from his or her Account pursuant to Section 9 either (i) five years following the date of the Participant’s Separation from Service, (ii) two years following the date of
such Separation from Service or (iii) subject to Section 9.4, immediately following the date of such Separation from Service.

election to change the time and form of the distribution of their Account, provided that the distribution election is made at least twelve months in advance of the newly elected distribution date and the previously scheduled distribution date and
the election is made no later than December 31, 2006. An election made pursuant to this Section 6.9 shall be treated as an initial distribution election and shall be subject to any special administrative rules imposed by the Administrator
including rules intended to comply with Section 409A of the Code and Notice 2005-1, Q&A-19. No election under this Section 6.9 shall (i) change the payment date of any distribution otherwise scheduled to be paid in 2006 or cause a

to discharge its duties under the Plan. Participants will at all times be 100% vested in their Accounts. Participants will be furnished statements of their Account values at least once each Plan Year. 
  

	8.	INVESTMENT OF CONTRIBUTIONS. 

 8.1 Available Investment Funds. The Administrator (acting through an authorized committee of one or more officers or other senior executives) shall have absolute discretion to select the available
Investments Funds which Participants may choose as the measure of the 

  

 11 

 
notional investment return on their Accounts in accordance with Section 8.2 The available Investment Funds shall be set forth in Attachment A, as
amended from time to time; provided, however, that Eligible Directors who participate in the Plan may also direct the investment of their Accounts in Phantom Shares. All amounts credited to Participant Accounts shall be treated as
though invested and reinvested only in those available Investment Funds. 
 8.2 Investment Directives. Investments in which a
Participant’s Account shall be treated as invested and reinvested as directed by the Participant. All dividends, interest, gains, losses and distributions of any nature earned with respect to the Investment Fund Shares in which the Account is
deemed invested shall be credited to the Account as though reinvested in additional shares of that Investment Fund. Expenses attributable to the acquisition of investments that mirror the deemed investments in a Participant’s Account shall be
charged to that Account. 
 8.3 Changes to Investment Funds. Except as otherwise provided in this Section 8.3, the
available Investment Funds set forth in Attachment A shall include the same investment funds selected by the Company’s Benefits Committee (the “Benefits Committee”) as available investment choices for participants in the
Company’s 401(k) Savings Plan (the “Savings Plan”). Notwithstanding the forgoing, should any investment fund selected by the Benefits Committee for inclusion as an available investment fund under the Savings Plan not be available for
Participants in this Plan, then Administrator (acting through an authorized committee of one or more officers or other senior executives) shall have the authority to select an alternative investment option that is substantially similar to the
unavailable investment fund. In all cases, the available investment funds under the Plan shall automatically change from time to time to reflect any changes made to the available investment funds under the Savings Plan, with such changes to become
effective as of the same date and time as the corresponding changes are made to the available investment funds under the Saving Plan without the need for formal amendment under this Plan. Attachment A shall be updated from time to time to reflect
such changes in investment options, and the Senior Vice President, Human Resources (or his or her authorized delegate) shall have the authority to execute documents and provide instruction to the Plan’s service providers with respect to the
selection or modification of the Investment Funds made available from time to time under the Plan. The foregoing provisions of this Section 8.3 shall not apply to the Phantom Shares in which Eligible Directors may elect to invest their
Accounts. 
  

	9.	DISTRIBUTION OF BENEFITS. 

 9.1 Distribution of Benefits to Participants. 
 (a) Except as otherwise
provided in Section 9.1(c), distributions under the Plan will be made in a cash lump sum or under a systematic withdrawal plan over a period not exceeding ten years. Such form of distribution shall be determined in accordance with Sections 9.2
and 9.3. 
 (b) Except as otherwise provided in Section 9.1(c), distributions under a systematic withdrawal plan
must be made in annual installments, in cash, over a period certain which does not extend for more than ten years. A systematic withdrawal plan may include a plan whereby one installment is elected. For purposes of the Plan, installment payments
shall be treated as a single aggregate distribution under Section 409A of the Code, and not as a series of individual installment payments. 
  

 12 

 (c) Notwithstanding Sections 9.1(a) and (b), distributions under the Plan to
Eligible Directors may, at the Participant’s election, be distributed in shares of the Employer’s common stock issuable under the Gilead Sciences, Inc. 2004 Equity Incentive Plan. Distributions of such common stock may be in a lump sum or
under a systematic withdrawal plan, as determined in accordance with Section 9.2 and 9.3. 
 9.2 Determination of Timing and
Method of Distribution. The Participant shall elect the timing and method of distribution for his or her Account. Such election shall be made at the time the Participant makes his or her initial Deferral Election, or in accordance with
Section 6.9 or 6.10 (as applicable), and will apply to all amounts credited to the Participant’s Account. Effective as of January 1, 2008, a Participant may make an Extended Deferral Election by submitting a completed and executed
election form approved by the Administrator for such purpose; provided, however, that such Extended Deferral Election must be made at least twelve (12) months prior to the date the Participant’s Account is otherwise scheduled
to become payable pursuant to the applicable provisions of Section 6 and the foregoing provisions of this Section 9, and such Extended Deferral Election shall in no event become effective or otherwise have any force or applicability until
the expiration of the twelve (12)-month period measured from the date such election is filed with the Administrator. Accordingly, the Extended Deferral Election shall become null and void if the pre-existing specified commencement date or event for
the distribution of the Participant’s Account occurs within that twelve (12)-month period. The Extended Deferral Election must specify a commencement date in a Plan Year that is at least five (5) Plan Years later than the Plan Year in
which the distribution of the Participant’s Account would have otherwise been made or commenced in the absence of the Extended Deferral Election. As part of the Extended Deferral Election, the Participant may also elect a different method of
distribution, provided the selected method complies with one of the methods of distribution permissible for that Account in accordance with the provisions of the Plan. Once the Extended Deferral Election becomes effective in accordance with the
foregoing provisions of this Section 9.2, such election shall remain in effect, whether or not the Participant continues in Employee status; provided, however, that in the event of the Participant’s death, the provisions of
Section 10.1 shall apply. A Participant may make only one Extended Deferral Election pursuant to this Section 9.2. 
 9.3
Default Distribution Election. If the Participant does not elect the method of distribution, the method of distribution will be a lump sum cash payment. Subject to Section 9.4 below, if the Participant does not elect the timing of
the distribution, the Participant’s Account balance will be distributed upon his or her Separation from Service. 
 9.4
Delayed Distribution to Specified Employees. Notwithstanding any other provision of this Section 9, a distribution made to a Participant who is a Specified Employee at the time of his or her Separation from Service will be delayed
for a minimum period of six months if the Participant’s distribution is triggered by such Separation from Service. Any payment that otherwise would have been made pursuant to this Section 9 during such period will be made in one lump sum
payment not later than the last day of the eight month following the 

  

 13 

 
month in which the Participant’s Separation from Service occurs. The determination of which Participants are Key Employees will be made by the
Administrator in accordance with Section 4.1(a)(21) of the Plan and Sections 416(i) and 409A of the Code and the Treasury Regulations thereunder. 
 9.5 Unforeseeable Emergency. Upon application by a Participant in the event of an Unforeseeable Emergency, the Administrator may its sole discretion authorize payment of all or part of the
Participant’s Account in one lump sum payment no later than the last day of the second month following the month in which the distribution is approved by the Administrator. The Administrator shall have complete discretion to accept or reject
the request and shall in no event authorize a distribution from the Participant’s Account in an amount in excess of that reasonably required to meet such financial hardship and the tax liability attributable to that distribution. The minimum
amount of a distribution due to a Participant’s Unforeseeable Emergency will be $1,000.00. 
 9.6 Prohibition on
Acceleration. Notwithstanding any other provision of the Plan to the contrary, no distribution will be made from the Plan that would constitute an impermissible acceleration of payment as defined in Section 409A(a)(3) of the Code and the
Treasury Regulations thereunder. However, the following mandatory distributions shall be made under the Plan: 
 (a) If
the aggregate balance of the Participant’s Account is not greater than the applicable dollar amount in effect under Code Section 401(g)(1)(B) at the time of the Participant’s Separation from Service and the Participant is not
otherwise at that time participating in any other non-qualified elective account balance plan subject to Code Section 409A and maintained by one or more Affiliated Companies, then that balance shall be distributed to the Participant in a lump
sum distribution as soon as administratively practical following such Separation from Service, whether or not the Participant elected that form of distribution or distribution event, but in no event later than the later of (i) the
end of the calendar year in which such Separation from Service occurs or (ii) the fifteenth (15th) day of the third (3rd) calendar month following the date of such Separation from Service, except to the extent a further deferral is
required to comply with the delayed distribution requirements set forth in Section 9.4. 
 (b) Should the
aggregate present value of all of the remaining unpaid installments due to a Participant who is receiving an installment distribution of his or her Account under the Plan fall below Twenty Thousand Dollars ($20,000), then those unpaid installments
shall be paid to the Participant in a single lump sum within thirty (30) days thereafter. 
 9.7 Adjustment for Investment
Experience. If any distribution under this Section 9 is not made in a single lump sum payment, the amount remaining in the Account after the first installment payment will be subject to adjustment (until distributed) to reflect the income
and gain or loss on the investments in which such Account is deemed invested pursuant to Section 8 and any expenses properly charged under the Plan and Trust to such Account. 
  

 14 

 9.8 Notice to Trustee. The Administrator will notify the Trustee in writing whenever any
Participant or Beneficiary is entitled to receive benefits under the Plan. The Administrator’s notice will indicate the form, amount and frequency of benefits that such Participant or Beneficiary will receive. 
 9.9 Time of Distribution. Except as provided in Section 9.4, in no event shall a distribution to a Participant be made or commence
later than: 
  

	 	•	 	 the last day of the second month following the month in which the Participant attains the elected age specified in his or her initial Deferral Election (or any
distribution election under Section 6.8 or 6.9), or 

  

	 	•	 	 the last day of the second month following the month in which occurs the Participant’s Separation from Service or any applicable anniversary of such Separation
from Service (if such event or anniversary is the designated distribution event for the Participant’s Account), or 

  

	 	•	 	 the last day of the second month following the month in which the deferred commencement date designated in the Participant Extended Deferral Election occurs.

  

	10.	EFFECT OF DEATH OF A PARTICIPANT. 

 10.1 Distributions. In the event of a Participant’s death, the Participant’s Account shall be distributed to the
Participant’s Beneficiary in a single lump sum cash payment. Such distribution shall be made as soon as administratively practicable after the date of the Participant’s death, but in no event later than the later of
(i) the close of the calendar year in which the Participant’s death occurs or (ii) the fifteenth (15th) day of the third (3rd) calendar month following the date of the Participant’s death. 
 10.2 Beneficiary Designation. 
 (a) Upon enrollment in the Plan, each Participant shall file a prescribed form with the Administrator or its designate naming a person or persons as the Beneficiary who will receive distributions payable under
the Plan in the event of the Participant’s death. If the Participant does not name a Beneficiary, or if none of the named Beneficiaries is living at the time payment is due, then the Beneficiary shall be the Participant’s spouse, or if
none, the Participant’s children in equal shares, or if none, the Participant’s estate. 
 (b) The
Participant may change the designation of a Beneficiary at any time in accordance with procedures established by the Administrator. Designation of a Beneficiary, or an amendment or revocation thereof, shall be effective only if made in the
prescribed manner and received by the Administrator prior to the Participant’s death. 
  

	11.	ESTABLISHMENT OF A TRUST. 

 11.1 Trust. The Participating Employers shall be responsible for the payment of benefits under the Plan attributable to their respective Eligible Employees and Eligible Directors. At their discretion,
the Participating Employers may establish one or more grantor trusts for the 

  

 15 

 
purpose of providing for the payment of benefits under the Plan; provided, however, that the establishment of such a trust shall not affect the
status of the Plan as an unfunded plan. Such trust or trusts may be irrevocable, but the assets thereof shall be subject to the claims of the Participating Employer’s creditors in the event of its bankruptcy or insolvency. Benefits paid the
Participants from any such trust shall be considered paid by the Participating Employer for purposes of meeting that Participating Employer’s obligations under the Plan. Notwithstanding the establishment of a trust, each Participating Employer
reserves the right at any time and from time to time to pay Plan benefits to Participants or their Beneficiaries in whole or in part from sources other than the Trust, in which case upon the Participating Employer’s request, that Participating
Employer shall receive a distribution from the Trust in an amount equal to the amount paid by that Participating Employer from sources other than the Trust to the Participant or Beneficiary in satisfaction of its obligations under the Plan, provided
that such distribution shall not exceed the amount of Trust assets previously allocated to such Participant or Beneficiary. 
 11.2
General Duties of Trustee. The Trustee shall manage, invest and reinvest the Trust Fund as provided in the Trust Agreement. The Trustee shall collect the income on the Trust Fund and make distributions therefrom, all as provided in the
Plan and in the Trust Agreement. 
  

	12.	AMENDMENT AND TERMINATION. 

 12.1 Amendment by Employer. The Employer reserves the authority to amend the Plan in its sole discretion. Each such amendment will become effective on the designated effective date of that amendment. Any
such amendment notwithstanding, no Participant’s Account will be reduced by such amendment below the amount to which the Participant would have been entitled had his or her Separation from Service occurred immediately prior to the date of the
amendment. The Employer may from time to time make any amendment to the Plan that may be necessary to satisfy applicable requirements of the Code or ERISA. The Board or other individual(s) designated by the Board may act on behalf of the Employer
for purposes of this Section 12.1. In no event shall any amendment to the Plan adversely affect the distribution provisions in effect for the Participant Accounts maintained under the Plan, and all amounts deferred prior to the date of any such
Plan amendment shall continue to become due and payable in accordance with the distribution provisions of Sections 6, 9 and 10 as in effect immediately prior to such amendment. Notwithstanding the foregoing, the Senior Vice President, Human
Resources (or his or her authorized delegate) shall have the authority to adopt amendments to the Plan that are required by law or provide administrative practices or clarity (specifically amendments not materially affecting either the financial
obligation of the Company or the level of benefits provided to a Participant or a Beneficiary) through the Plan. Any such amendments made by the Senior Vice President, Human Resources or his or her authorized delegate) shall be subject to the
limitations set forth above. 
 12.2 Retroactive Amendments. An amendment made by the Employer in accordance with
Section 12.1 may be made effective on a date prior to the first day of the Plan Year in which adopted, if such amendment is necessary or appropriate to enable the Plan and Trust to satisfy the applicable requirements of the Code or ERISA or to
conform the Plan to any change in federal law or to any regulations or ruling thereunder. Any retroactive amendment by the 

  

 16 

 
Employer will be subject to the provisions of Section 12.1. The Board or any officer of the Company designated by the Board, including the Senior Vice
President, Human Resources, shall have the authority to act on behalf of the Employer for purposes of this Section 12.2. 
 12.3
Termination. The Employer has adopted the Plan with the intention and expectation that contributions will be continued indefinitely. However, the Employer has no obligation or liability whatsoever to maintain the Plan for any length of time
and may suspend the Plan by discontinuing contributions under the Plan or terminate the Plan at any time in its discretion without any liability hereunder for any such suspension or termination. Except as otherwise provided in Sections 12.3(a),
(b) or (c) below, the termination of the Plan shall not affect the distribution provisions in effect for the Participant Accounts maintained hereunder, and all amounts deferred prior to the date of any such Plan termination shall continue
to become due and payable in accordance with the distribution provisions of Sections 6, 9 and 10 as in effect immediately prior to such plan termination. 
 (a) Except as provided in Sections 12.3(b) and (c) below, in the event of a termination of the Plan during a period in which the Employer has not experienced a financial downturn, the Participant Accounts
maintained under the Plan may, in the Employer’s discretion, be distributed within the period beginning twelve (12) months after the date the Plan is terminated and ending twenty-four (24) months after the date of such plan
termination, or pursuant to Section 6, 9 or 10 of the Plan, if earlier. If the Plan is terminated and Accounts are distributed, the Employer and the other Participating Employers shall also terminate and liquidate all other non-qualified
elective account balance deferred compensation plans maintained by them and shall not adopt a new non-qualified elective account balance deferred compensation plan for at least three (3) years after the date the Plan is terminated. 

(b) The Employer and the other Participating Employers may terminate the Plan thirty (30) days prior to or within twelve
(12) months following a Change of Control and distribute, within the twelve (12)-month period following the termination of the Plan, the Accounts of the Participants affected by such Change in Control If the Plan is terminated and Accounts are
distributed, the Employer and the other Participating Employers shall also terminate all other non-qualified elective account balance deferred compensation plans sponsored by them in which such Participants participate, and all of the benefits
accrued under those terminated plans by such Participants shall be distributed to them within twelve (12) months following the termination of such plans. 
 (c) The Employer may terminate the Plan upon a corporate dissolution of the Employer that is taxed under Section 331 of the
Code or with the approval of a bankruptcy court pursuant to 11 U.S.C. Section 503(b)(1)(A), provided that the Participant Accounts are distributed and included in the gross income of the Participants by the later of (i) the Plan Year in
which the Plan terminates or (ii) the first Plan Year in which payment of the Accounts is administratively practicable. 
  

	13.	MISCELLANEOUS. 

 13.1
Withholding Taxes. All distributions under the Plan shall be subject to reduction in order to reflect tax withholding obligations imposed by law. 
  

 17 

 13.2 Participant’s Unsecured Rights. The Account of any Participant, and such
Participant’s right to receive distributions from his or her Account, shall be considered an unsecured claim against the general assets of the Employer; such Accounts are unfunded bookkeeping entries. The Employer considers the Plan to be
unfunded for tax purposes and for purposes of Title I of ERISA. No Participant shall have an interest in, or make claim against, any specific asset of the Employer (or any other Participating Employer) pursuant to the Plan. 
 13.3 Limitation of Rights. Neither the establishment of the Plan and the Trust, nor any amendment thereof, nor the creation of any fund or
account, nor the payment of any benefits, will be construed as giving to any Participant or other person any legal or equitable right against any Participating Employer, the Administrator or the Trustee, except as provided herein. In no event shall
the terms of employment or service of any Participant be modified or in any way affected hereby. 
 13.4 Nonalienability of
Benefits. Except as provided in Sections 13.4(a) and (b) with respect to domestic relations orders, the benefits provided hereunder will not be subject to alienation, assignment, garnishment, attachment, execution or levy of any kind,
either voluntarily or involuntarily, and any attempt to cause such benefits to be so subjected will not be recognized, except to such extent as may be required by law. 
 (a) The procedures established by the Administrator for the determination of the qualified status of domestic relations orders and
for making distributions under qualified domestic relations orders, as provided in Section 206(d) of ERISA, shall apply to the Plan, to the extent applicable. 
 (b) To the extent required to comply with a qualified domestic relations order, amounts awarded to an alternate payee under a
qualified domestic relations order shall be distributed in the form of a lump sum distribution as soon as administratively feasible following the determination of the qualified status of the domestic relations order. To the extent that the qualified
domestic relations order does not require an immediate lump sum distribution, the alternate payee shall have all rights regarding investment elections and distribution elections and withdrawal rights as if such alternate payee were a Participant.
For purposes of determining distributions to an alternate payee, “Separation from Service” shall be the Separation from Service of the Participant whose Account is the subject of the qualified domestic relations order. 
 13.5 Facility of Payment. In the event the Administrator determines, on the basis of medical reports or other evidence satisfactory to the
Administrator, that the recipient of any benefit payments under the Plan is incapable of handling his or her affairs by reason of minority, illness, infirmity or other incapacity, the Administrator may direct the Trustee to disburse such payments to
a person or institution designated by a court which has jurisdiction over such recipient or a person or institution otherwise having the legal authority under state law for the care and control of such recipient. The receipt by such person or
institution of any such payments will be complete acquittance therefore, and any such payment to the extent thereof, will discharge the liability of the Participating Employer and the Trust for the payment of benefits hereunder to such recipient.

  

 18 

 13.6 Governing Law. The validity, interpretation, construction and performance of the Plan
shall be governed by ERISA, and, to the extent that they are not preempted, by the laws of the State of California, excluding California’s choice-of-law provisions. 
  

	14.	PLAN ADMINISTRATION.

in part, the Administrator shall provide the person making the claim with written notice of the denial within the period specified in Section 14.2(b) above. The notice shall set forth the specific reason for the denial, reference to the
specific Plan provisions upon which the denial is based, a description of any additional material or information necessary to perfect the claim, an explanation of why such information is required, and an explanation of the Plan’s appeal

original denial of the claim. 
 (3) The Administrator shall issue a written decision within a reasonable period of
time but not later than sixty (60) days after receipt of the appeal, unless special circumstances require an extension of time for processing, in which case the written decision shall be issued as soon as possible, but not later than one

extension and the date by which the Administrator expects to reach a decision on the appeal. 
  

 20 

 (4) If the decision on the appeal denies the claim in whole or in part written
notice shall be furnished to the appellant. Such notice shall state the reason(s) for the denial, including references to specific Plan provisions upon which the denial was based. The notice shall state that the appellant is entitled to receive,
upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the claim for benefits. The notice shall describe any voluntary appeal procedures offered by the Plan and the
appellant’s right to obtain the information about such procedures. The notice shall also include a statement of the appellant’s right to bring an action under Section 502(a) of ERISA. 
 (5) The decision of the Administrator on the appeal shall be final, conclusive and binding upon all persons and shall be given the
maximum possible deference allowed by law. 
 (e) Exhaustion of Remedies. No legal or equitable action for
benefits under the Plan shall be brought unless and until the claimant has submitted a written claim for benefits in accordance with Section 14.2(b) above, has been notified that the claim is denied in accordance with Section 14.2(c)
above, has filed a written request for a review of the claim in accordance with Section 14.2(d) above, and has been notified in writing that the Administrator has affirmed the denial of the claim in accordance with Section 14.2(d) above;
