 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. 
 (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 to grant such Awards and may limit such authority as the Board determines from time to time.

 (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.

the exercise price of any Option awarded under the Plan shall be subject to stockholder approval as provided in Section 7(b), and (C) canceling an Option at a time when its exercise price exceeds the Fair Market Value of the underlying
Shares, in exchange for another Option, 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; 
 (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 
 (ix) to take such other action, not inconsistent with the terms of
the Plan, as the Administrator deems appropriate.

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 

  

 -6- 

 
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 conditions. Such awards include, without limitation, Options, SARs, Restricted Stock, Dividend Equivalent Rights, Performance Units, Performance Shares, or Phantom Shares. An Award may consist of one such security or benefit, or
two or more of them in any combination or alternative. 
 (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 Shares subject
to Options designated as Incentive Stock Options which become exercisable for the first time by a Grantee during any calendar year (under all plans of the Company or any Parent or Subsidiary of the Company) exceeds $100,000, such excess Options, to
the extent of the Shares covered thereby in excess of the foregoing limitation, shall be treated as Nonstatutory Stock Options. For this purpose, Incentive Stock Options shall be taken into account in the order in which they were granted, 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, form of
payment (cash, Shares, or other consideration) upon settlement of the Award, payment contingencies, and satisfaction of any performance criteria. The performance criteria established by the Administrator may be based on any one of, or combination
of, the following: (i) revenue, (ii) achievement of specified milestones in the discovery and development of one or more of the Company’s products, (iii) achievement of specified milestones in the commercialization of one or more
of the Company’s products, (iv) achievement of specified milestones in the manufacturing of one or more of the Company’s products, (v) expense targets, (vi) personal management objectives, (vii) share price (including,
but not limited to, growth measures and total shareholder return), (viii) earnings per share, (ix) operating efficiency, (x) operating margin, (xi) gross margin, (xii) return measures (including, but not limited to, return
on assets, capital, equity, or sales), (xiii) net sales growth, (xiv) productivity ratios, (xv) operating income, (xvi) net operating profit, (xvii) net earnings or net income (before or after taxes), (xviii) cash flow
(including, but not limited to, operating cash flow, free cash flow, and cash flow return on capital), (xix) earnings before or after interest, taxes, depreciation, and/or amortization, (xx) economic value added, (xxi) market share,
(xxii) customer satisfaction, (xxiii) working capital targets, and (xxiv) other measures of performance selected by the Administrator. Partial achievement of the specified criteria may result in a payment or vesting corresponding to
the degree of achievement as specified in the Award Agreement. 
 (d) Acquisitions and Other Transactions. The Administrator may issue
Awards under the Plan in settlement, assumption or substitution for, outstanding awards or obligations to grant future awards in connection with the Company or a Related Entity acquiring 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 consideration upon exercise 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.

  

 -7- 

 (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 1,250,000 Shares. The maximum number of Shares with respect to which Restricted Stock, Performance Shares, Performance Units, SARs, or Phantom Shares, in the aggregate, may be granted to any Grantee in any fiscal year of the
Company shall be 200,000 Shares. In connection with an Employee’s or Consultant’s (i) commencement of Continuous Active Service or (ii) promotion, an Employee or Consultant may be granted Options for up to an additional 500,000
Shares or Restricted Stock, Performance Shares, Performance Units, SARs, or Phantom Shares, in the aggregate, for up to an additional 100,000 shares which shall not count against the limit 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 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 an Option (or in the case of a SAR, the base amount on which the stock appreciation is calculated is reduced to reflect a reduction in the Fair Market Value of the Common Stock), 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 will not be treated as an increase in the number of Shares 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, 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. 
 (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 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, such price as is 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 or purchase 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) 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 or attestation equal to the aggregate exercise price of the Shares as to which said Award shall be exercised, provided,
however, that Shares acquired under the Plan or any other equity compensation plan or agreement of the Company must have been held by the Grantee for a period of more than six months; 
 (iv) with respect to Options, payment through a traditional broker-dealer sale and remittance procedure pursuant to which the Grantee (A) shall
provide written instructions to a Company designated brokerage firm to effect the immediate sale of some or all of the purchased Shares and remit to the Company 

  

 -9- 

 
sufficient funds to cover the aggregate exercise price payable for the purchased Shares and (B) shall provide written directives to the Company to
deliver the certificates for the purchased Shares directly to such brokerage firm in order to complete the sale transaction; 
 (v) with
respect to Options, payment through an internet-based broker-dealer sale and remittance procedure pursuant to which the Grantee (A) shall establish and maintain an account with the internet-based broker-dealer to effect the sale of some or all
of the purchased Shares and ensure that such account contains sufficient funds to cover the aggregate exercise price payable for the purchased Shares and (B) shall execute the transaction with the internet-based broker-dealer who will then
cause the purchased Shares to be deposited into the Grantee’s account in order to complete the sale transaction; or 
 (vi) any
combination of the foregoing methods of payment. 
 (d) Taxes. No Shares shall be delivered under the Plan to any Grantee or other
person until such Grantee or other person has made arrangements acceptable to the Administrator for the satisfaction of any federal, state, local or non-U.S. income and employment tax withholding obligations, including, without limitation,
obligations incident to the receipt of Shares or the disqualifying disposition of Shares received on exercise of an Incentive Stock Option. Upon exercise of an Award the Company shall withhold or collect from Grantee an amount sufficient to satisfy
such tax obligations. 
 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 which vest on the basis of the Grantee’s Continuous Active 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 which provide for vesting upon the attainment of performance goals shall provide for a performance period of at least 12 months.

 (ii) An Award shall be deemed to be exercised when written notice of such exercise 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 and full payment for the Shares with respect to which the Award is exercised, including, to the extent selected, use of the broker-dealer sale and remittance
procedure to pay the purchase price as provided in Section 7(c)(iv). 
 (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 Active 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 Active 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. 
 (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 a Grantee’s Continuous Active Service 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. 
  

 -10- 

 9. Conditions Upon Issuance of Shares. 
 (a) Shares shall not be issued pursuant to the exercise of an Award unless the exercise 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 exercise of an Award, the Company may require the person exercising such Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for
investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by any Applicable Laws. 
 10. Adjustments Upon Changes in Capitalization. If any change is made in the Common Stock subject to the Plan, or subject to any Award (through
merger, consolidation, reorganization, recapitalization, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or otherwise), the Plan will
be appropriately adjusted in the class(es) and maximum number of shares subject to the Plan pursuant to Section 3(a), and the maximum number of shares subject to award 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 appropriately adjusted in the classes(es) and the number of shares and price 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. 
 11. Change in Control. 
 (a) Effect of Change in Control on Awards. In the event of a Change in
Control, then, at the sole discretion of the Board and to the extent permitted by applicable law: (i) any surviving corporation shall assume any Awards outstanding under the Plan or shall substitute similar Awards for those outstanding under
the Plan, (ii) the time during which such Awards may be exercised shall be accelerated and the Awards terminated if not exercised prior to the Change in Control, or (iii) such Awards shall continue in full force and effect. 
 (b) Acceleration of Award Upon Change in Control. Notwithstanding any other provisions of this Plan to the contrary, if a Change in Control occurs
and if within one month before or within the Applicable Acceleration Period after the date of such Change in Control (1) the Continuous Active 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 Active 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 those Awards held by a Grantee at the
time of such termination, 100% of the unvested Shares covered by such Awards shall vest and become exercisable (or reacquisition or repurchase rights held by the Company shall lapse with respect to 100% of the Shares still subject to such rights, as
appropriate) 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 at any time within 90 days 

  

 -11- 

 
preceding the date of a Change in Control or 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 at any time within 90 days preceding the date of a Change in Control 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 such offices or positions, except in connection with the termination of the
Grantee’s Continuous Active 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
Grantee’s current work site, except for reasonably required travel on the business of the Company or a Related Entity which is not materially greater than such travel requirements prior to the Change in Control; (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 90 days preceding the date of a
Change in Control 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 for under each other employee benefit plan, program and practice in which the Grantee was
participating at any time within 90 days preceding the date of a Change in Control 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. 
 (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. 
  

 -12- 

 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 Active 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 Active 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 Active 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 California (with the exception of its conflict of law provisions).

 1. PURPOSE. 
 (a) The purpose of the Employee Stock Purchase Plan (“the Plan”)
is to provide a means by which employees of GILEAD SCIENCES, INC., a Delaware corporation (the “Company”), and its Affiliates, as defined in subparagraph 1(c), which are
designated as provided in subparagraph 2(b), may be given an opportunity to purchase stock of the Company. 
 (b) Plan initially was
adopted on November 15, 1991 and subsequently amended on May 25, 1994 (the “Initial Plan”). The Initial Plan was first amended and restated in its entirety effective as of January 22, 1998 (the “Amended and Restated
Plan”). The Amended and Restated Plan is hereby further amended and restated in its entirety effective as of January 22, 2007. The terms of the Initial Plan (other than the aggregate number of shares issuable thereunder) and the terms of
the Amended and Restated Plan (other than the Termination Date) shall remain in effect and apply to all options granted under the relevant plan. 
 (c) The word “Affiliate” as used in the Plan means any parent corporation or subsidiary corporation of the Company, as those terms are defined in Sections 424(e) and (f), respectively, of the Internal Revenue Code of 1986,
as amended (the “Code”). 
 (d) The Company, by means of the Plan, seeks to retain the services of its employees, to secure
and retain the services of new employees, and to provide incentives for such persons to exert maximum efforts for the success of the Company. 
 (e) The Company intends that the rights to purchase stock of the Company granted under the Plan be considered options issued under an “employee stock purchase plan” as that term is defined in Section 423(b) of the
Code. 
 2. ADMINISTRATION. 
 (a) The Plan shall be administered by the Board of Directors (the “Board”) of the Company unless and until the Board delegates
administration to a Committee, as provided in subparagraph 2(c). Whether or not the Board has delegated administration, the Board shall have the final power to determine all questions of policy and expediency that may arise in the administration of
the Plan. 
 (b) The Board shall have the power, subject to, and within the limitations of, the express provisions of the Plan:

 (i) To determine when and how rights to purchase stock of the Company shall be granted and the provisions of each offering of such
rights (which need not be identical). 
  

 1 

 (ii) To designate from time to time which Affiliates of the Company shall be eligible to
participate in the Plan. 
 (iii) To construe and interpret the Plan and rights granted under it, and to establish, amend and revoke
rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully
effective. 
 (iv) To amend the Plan as provided in paragraph 13. 
 (v) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests of the
Company. 
 (c) The Board may delegate administration of the Plan to a Committee composed of not fewer than two (2) members of
the Board (the “Committee”). If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board, subject, however, to such resolutions,
not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may abolish the Committee at any time and revest in the Board the administration of the Plan. 
 (d) The Board (or the Committee, as appropriate) may, from time to time, employ an entity unrelated to the Company to assist with administration,
recordkeeping and other ministerial duties in connection with the Plan (a “Third Party Administrator”). 
 3.
SHARES SUBJECT TO THE PLAN. 
 Subject to the provisions of paragraph 12 relating to adjustments upon changes in stock, the stock
that may be sold pursuant to rights granted under the Plan shall not exceed in the aggregate [sixteen million six hundred forty thousand (16,640,000)]1 shares of the Company’s $.001 par value common stock (the “Common Stock”). If any right granted under the Plan shall for any reason terminate without having been exercised, the Common
Stock not purchased under such right shall again become available for the Plan. The stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise. 
 4. GRANT OF RIGHTS; OFFERING. 
 The Board or the Committee may from time to time grant or provide for the grant of rights to purchase Common Stock of the Company under the Plan to
eligible employees (an “Offering”) on a date or dates (the “Offering Date(s)”) selected by the Board or the Committee. Each Offering shall be in such form and shall contain such terms and conditions as the Board or the Committee
shall deem appropriate. If an employee has more than one right outstanding under the Plan, unless he or she otherwise indicates: (1) the most recent online action taken or the most recent written designation or notice made, as applicable, by
that employee will be deemed to apply to all of his or her rights under the Plan, and (2) a right with a lower exercise price (or an earlier-granted right, if two rights have identical exercise prices), will be exercised to the fullest possible
extent before a right with a higher exercise price (or a later-granted right, if two rights have identical exercise prices) will be exercised. The provisions of separate Offerings need not be identical, but each Offering shall include (through
incorporation of the provisions of this Plan by reference in the Offering or otherwise) the substance of the provisions contained in paragraphs 5 through 8, inclusive. 

	 1
	 Maximum number of shares consists of 12,640,000 shares authorized July 29, 1999; and an additional
4,000,000 shares to be authorized at the 2007 annual stockholder meeting.

 5. ELIGIBILITY. 
 (a) Rights may be granted only to employees of the Company or, as the Board or the Committee may designate as provided in subparagraph 2(b), to
employees of any Affiliate of the Company. Except as provided in subparagraph 5(b), an employee of the Company or any Affiliate shall not be eligible to be granted rights under the Plan, unless, on the Offering Date, such employee has been in the
employ of the Company or any Affiliate for such continuous period preceding such grant as the Board or the Committee may require, but in no event shall the required period of continuous employment be equal to or greater than two (2) years. In
addition, unless otherwise determined by the Board or the Committee and set forth in the terms of the applicable Offering, no employee of the Company or any Affiliate shall be eligible to be granted rights under the Plan, unless, on the Offering
Date, such employee’s customary employment with the Company or such Affiliate is at least twenty (20) hours per week and at least five (5) months per calendar year. 
 (b) The Board or the Committee may provide that, each person who, during the course of an Offering, first becomes an eligible employee of the
Company or designated Affiliate will, on a date or dates specified in the Offering which coincides with the day on which such person becomes an eligible employee or occurs thereafter, receive a right under that Offering, which right shall thereafter
be deemed to be a part of that Offering. Such right shall have the same characteristics as any rights originally granted under that Offering, as described herein, except that: 
 (i) the date on which such right is granted shall be the “Offering Date” of such right for all purposes, including determination of the
exercise price of such right; 
 (ii) the Offering Period (as defined below) for such right shall begin on its Offering Date and end
coincident with the end of such Offering; 
 (iii) the Offering Date shall constitute the beginning of a Purchase Period; and

 (iv) the Board or the Committee may provide that if such person first becomes an eligible employee within a specified period of
time before the end of the Offering Period (as defined below) for such Offering, he or she will not receive any right under that Offering. 
 (c) No employee shall be eligible for the grant of any rights under the Plan if, immediately after any such rights are granted, such employee owns stock possessing five percent (5%) or more of the total combined voting power or
value of all classes of stock of the Company or of any Affiliate. For purposes of this subparagraph 5(c), the rules of Section 424(d) of the Code shall apply in determining the stock ownership of any employee, and stock which such employee may
purchase under all outstanding rights and options shall be treated as stock owned by such employee. 
 (d) An eligible employee may be
granted rights under the Plan only if such rights, together with any other rights granted under “employee stock purchase plans” of the Company and any Affiliates, as specified by Section 423(b)(8) of the Code, do not permit such
employee’s rights to purchase stock of the Company or any Affiliate to accrue at a rate which exceeds twenty-five thousand dollars ($25,000) of fair market value of such stock (determined at the time such rights are granted) for each calendar
year in which such rights are outstanding at any time. 
 (e) Officers of the Company and any designated Affiliate shall be eligible
to participate in Offerings under the Plan, provided, however, that the Board may provide in an Offering that certain employees who are highly compensated employees within the meaning of Section 423(b)(4)(D) of the Code shall not be eligible to
participate. 
  

 3 

 6. RIGHTS; PURCHASE PRICE. 
 (a) On each Offering Date, each eligible employee, pursuant to an Offering made under the Plan, shall be granted the right to purchase the number
of shares of Common Stock of the Company purchasable with up to fifteen percent (15%) (or such lower percentage as the Board determines for a particular Offering) of such employee’s Earnings (as defined in Section 7(a)) during the
period which begins on the Offering Date (or such later date as the Board determines for a particular Offering) and ends on the date stated in the Offering, which date shall be no more than twenty-seven (27) months after the Offering Date (the
“Offering Period”). In connection with each Offering made under this Plan, the Board or the Committee shall specify a maximum number of shares which may be purchased by any employee as well as a maximum aggregate number of shares which may
be purchased by all eligible employees pursuant to such Offering. Each Offering Period may contain more than one Exercise Date (as defined in the Offering) in which case there will be multiple “Purchase Periods,” the first commencing with
the Offering Date and ending with the first Exercise Date of that Offering and subsequent ones commencing with the first day following the immediately preceding Exercise Date and ending with the next Exercise Date of that Offering. Where an Offering
contains more than one Exercise Date, the Board or the Committee may specify a maximum aggregate number of shares which may be purchased by all eligible employees on any given Exercise Date under the Offering. If the aggregate purchase of shares
upon exercise of rights granted under the Offering would exceed any such maximum aggregate number, the Board or the Committee shall make a pro rata allocation of the shares available in as nearly a uniform manner as shall be practicable and as it
shall deem to be equitable. 
 (b) In connection with each Offering made under the Plan, the Board or the Committee may specify a
maximum number of shares that may be purchased by any employee as well as a maximum aggregate number of shares that may be purchased by all eligible employees pursuant to such Offering. In addition, in connection with each Offering that contains
more than one Purchase Date, the Board or the Committee may specify a maximum aggregate number of shares which may be purchased by all eligible employees on any given Purchase Date under the Offering. If the aggregate purchase of shares upon
exercise of rights granted under the Offering would exceed any such maximum aggregate number, the Board or the Committee shall make a pro rata allocation of the shares available in as nearly a uniform manner as shall be practicable and as it shall
deem to be equitable. 
 (c) The purchase price of stock acquired pursuant to rights granted under the Plan shall be not less than the
lesser of: 
 (i) an amount equal to eighty-five percent (85%) of the Fair Market Value of the stock on the Offering Date; or

 (ii) an amount equal to eighty-five percent (85%) of the Fair Market Value of the stock on the Exercise Date. 
 (d) As of any date, “Fair Market Value” is defined as the closing sales price for the Company’s stock (or the closing bid, if no
sales were reported) on such day as quoted on The Nasdaq Stock Market or as reported by such other source as the Board deems reliable. If there are no quotations for the relevant day, “Fair Market Value” is defined with reference to the
most recent preceding date on which there are quotations. 
 7. PARTICIPATION; WITHDRAWAL;
TERMINATION. 
 (a) An eligible employee may become a participant in an Offering by accessing the
Third Party Administrator’s website and electronically enrolling within the time specified in the Offering. During such enrollment process, the employee shall authorize payroll deductions of up to fifteen percent (15%) (or such lower
percentage as the Board determines for a particular Offering) of such employee’s Earnings during the Offering Period. “Earnings” is defined as an employee’s total compensation, including all salary, wages and other remuneration
paid to an employee (including amounts elected to be deferred under any cash or deferred arrangement or cafeteria plan established by the Company pursuant to Sections 401(k) and 125, respectively, of the Code and excluding amounts elected to be
deferred under any nonqualified deferred compensation plan established by the Company and referral pay which is paid in recognition of referring an employee candidate), overtime pay, 

  

 4 

 
commissions, bonuses, profit sharing, any special payments for extraordinary services, provided, however, that the Board in its sole discretion may limit the
above definition from time to time with respect to each Offering. The payroll deductions made for each participant shall be credited to an account for such participant under the Plan and shall be deposited with the general funds of the Company. A
participant may reduce, increase or begin such payroll deductions after the beginning of any Offering Period only as provided for in the Offering. A participant may make additional payments into his or her account only if specifically provided for
in the Offering and only if the participant has not had the maximum amount withheld during the Offering Period. 
 (b) At any time
during an Offering Period a participant may terminate his or her payroll deductions under the Plan and withdraw from the Offering by accessing the Third Party Administrator’s website and electronically electing to withdraw. Such withdrawal may
be elected at any time prior to the end of the Purchase Period. Upon such withdrawal from the Offering by a participant, the Company shall distribute to such participant all of his or her accumulated payroll deductions (reduced to the extent, if
any, such deductions have been used to acquire stock for the participant) under the Offering, without interest unless the terms of the Offering specifically so provide, and such participant’s interest in that Offering shall be automatically
terminated. A participant’s withdrawal from an Offering will have no effect upon such participant’s eligibility to participate in any other future Offerings under the Plan but such participant will be required to electronically re-enroll
in order to participate in subsequent Offerings under the Plan. 
 (c) Rights granted pursuant to any Offering under the Plan shall
terminate immediately upon cessation of any participating employee’s employment with the Company or an Affiliate, for any reason, and the Company shall distribute to such terminated employee all of his or her accumulated payroll deductions
(reduced to the extent, if any, such deductions have been used to acquire stock for the terminated employee), under the Offering, without interest unless the terms of the Offering specifically so provide. 
 (d) Rights granted under the Plan shall not be transferable by a participant otherwise than by will or the laws of descent and distribution, or by
a beneficiary designation as provided in paragraph 14 and, otherwise during his or her lifetime, shall be exercisable only by the person to whom such rights are granted. 
 8. EXERCISE. 
 (a) On each exercise date, as defined in the
relevant Offering (an “Exercise Date”), each participant’s accumulated payroll deductions (without any increase for interest unless the terms of the Offering specifically so provide) will be applied to the purchase of whole shares of
stock of the Company, up to the maximum number of shares permitted pursuant to the terms of the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional shares shall be issued upon the exercise of rights
granted under the Plan. The amount, if any, of accumulated payroll deductions remaining in each participant’s account after the purchase of shares which is less than the amount required to purchase one share of stock on the final Exercise Date
of an Offering shall be held in each such participant’s account for the purchase of shares under the next Offering under the Plan, unless such participant withdraws from such next Offering, as provided in subparagraph 7(b), or is no longer
eligible to be granted rights under the Plan, as provided in paragraph 5, in which case such amount shall be distributed to the participant after said final Exercise Date, without interest unless the terms of the Offering specifically so provide.
The amount, if any, of accumulated payroll deductions remaining in any participant’s account after the purchase of shares which is equal to the amount required to purchase whole shares of stock on the final Exercise Date of an Offering shall be
distributed in full to the participant after such Exercise Date, without interest. 
 (b) No rights granted under the Plan may be
exercised to any extent unless the Plan (including rights granted thereunder) is covered by an effective registration statement pursuant to the Securities Act of 1933, as amended (the “Securities Act”). If on an Exercise Date of any
Offering hereunder the Plan is not so registered, no rights granted under the Plan or any Offering shall be exercised on said Exercise Date and all payroll deductions accumulated during the purchase period (reduced to the extent, if any, such
