for a Share as quoted on such exchange or system for such date or, if there is no closing sales price for a Share on the date in question, the closing sales price for a Share on the last
preceding date for which such quotation exists, as reported in The Wall Street Journal or such other source as the Administrator deems reliable; 
 (b)        If the Common Stock is not listed on an established securities exchange, national market system or automated quotation system, but the Common Stock is

prices for a Share on the last preceding date for which such information exists, as reported in The Wall Street Journal or such other source as the Administrator deems reliable; or

treated as a Subsidiary to the extent either (a) such entity is treated as a disregarded entity under Treasury Regulation Section 301.7701-3(a) by reason of the Company or any other Subsidiary that is a corporation being the sole owner of
such entity, or (b) such entity elects to be classified as a corporation under Treasury Regulation Section 301.7701-3(a) and such entity would otherwise qualify as a Subsidiary.

 4.1         Offering Periods. The Administrator 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 during one or more periods (each, an “Offering Period”) selected by the Administrator
commencing on such dates (each, an “Enrollment Date”) selected by the Administrator. The terms and conditions applicable to each Offering Period shall be set forth in an “Offering Document” adopted by
the Administrator, which Offering Document shall be in such form and shall contain such terms and conditions as the Administrator shall deem appropriate and shall be incorporated by reference into and made part of the Plan and shall be attached
hereto as part of the Plan. The provisions of separate Offering Periods under the Plan need not be identical. 

4.2         Offering Documents. Each Offering Document with respect to an
Offering Period shall specify (through incorporation of the provisions of this Plan by reference or otherwise): 
 (a)        the length of the Offering Period, which period shall not exceed twenty-seven months;

 ELIGIBILITY AND PARTICIPATION 

5.1         Eligibility. Any Eligible Employee who shall be employed by
the Company or a Designated Subsidiary on the day immediately preceding a given Enrollment Date for an Offering Period shall be eligible to participate in the Plan during such Offering Period, subject to the requirements of this Article 5 and the
limitations imposed by Section 423(b) of the Code and the Treasury Regulations thereunder. 

5.2         Enrollment in Plan. 

(a)        Except as otherwise set forth in Section 5.8 or in an Offering
Document, an Eligible Employee may become a Participant in the Plan for an Offering Period by delivering a subscription agreement to the Company by such time prior to the Enrollment Date for such Offering Period (or such other date specified in the
Offering Document) designated by the Administrator and in such form as the Administrator provides. 

(b)        Each such agreement shall designate a whole percentage of such
Eligible Employee’s Compensation to be withheld by the Company or the Designated Subsidiary employing such Eligible Employee on each payday during the Offering Period as payroll deductions under the Plan. An Eligible Employee may designate any
whole percentage of Compensation that is not less than 1% and not more than the maximum percentage specified by the Administrator in the applicable Offering Document (which percentage shall be 20% in the absence of any such designation) as payroll
deductions. 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. 

(c)        A Participant may increase or decrease the percentage of Compensation
designated in his or her subscription agreement, subject to the limits of this Section 5.2, or may suspend his or her payroll deductions, at any time during an Offering Period; provided, however, that the Administrator may limit
the number of changes a Participant may make to his or her payroll deduction elections during each Offering Period in the applicable Offering Document (and in the absence of any specific designation by the Administrator, a Participant shall be
allowed one change to his or her payroll deduction elections during each Offering Period). Any such change or suspension of payroll deductions shall be effective with the first full payroll period following five business days after the
Company’s receipt of the new subscription agreement (or such shorter or longer period as may be specified by the Administrator in the applicable Offering Document). In the event a Participant suspends his or her payroll deductions, such
Participant’s cumulative payroll deductions prior to the suspension shall remain in his or her account and shall be applied to the purchase of Shares on the next occurring Purchase Date and shall not be paid to such Participant unless he or she
withdraws from participation in the Plan pursuant to Article 7. 

  
 6 

 (d)        Except as otherwise set
forth in an Offering Document, a Participant may participate in the Plan only by means of payroll deduction and may not make contributions by lump sum payment for any Offering Period. 

5.3         Payroll Deductions. Except as otherwise provided in the
applicable Offering Document, payroll deductions for a Participant shall commence on the first payroll following the Enrollment Date and shall end on the last payroll in the Offering Period to which his or her authorization is applicable, unless
sooner terminated by the Participant as provided in Article 8. 

5.4         Effect of Enrollment. A Participant’s completion of a
subscription agreement will enroll such Participant in the Plan for each subsequent Offering Period on the terms contained therein until the Participant either submits a new subscription agreement, withdraws from participation under the Plan as
provided in Article 7 or otherwise becomes ineligible to participate in the Plan. 

5.5         Limitation on Purchase of Common Stock. An Eligible Employee
may be granted rights under the Plan only if such rights, together with any other rights granted to such Eligible Employee under “employee stock purchase plans” of the Company, any Parent or any Subsidiary, 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 Parent or Subsidiary to accrue at a rate that exceeds $25,000 of fair market value of such stock (determined as of the first day of
the Offering Period during which such rights are granted) for each calendar year in which such rights are outstanding at any time. This limitation shall be applied in accordance with Section 423(b)(8) of the Code. 

5.6         Decrease or Suspension of Payroll Deductions. Notwithstanding
the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 5.5 or the other limitations set forth in this Plan, a Participant’s payroll deductions may be suspended by the Administrator at any time
during an Offering Period. The balance of the amount credited to the account of each Participant that has not been applied to the purchase of Shares by reason of Section 423(b)(8) of the Code, Section 5.5 or the other limitations set forth
in this Plan shall be paid to such Participant in one lump sum in cash as soon as reasonably practicable after the Purchase Date. 
 5.7         Foreign Employees. In order to facilitate participation in the Plan, the Administrator may provide for such special terms applicable to
Participants who are citizens or residents of a foreign jurisdiction, or who are employed by a Designated Subsidiary outside of the United States, as the Administrator may consider necessary or appropriate to accommodate differences in local law,
tax policy or custom. Such special terms may not be more favorable than the terms of rights granted under the Plan to Eligible Employees who are residents of the United States. Moreover, the Administrator may approve such supplements to, or
amendments, restatements or alternative versions of, this Plan as it may consider necessary or appropriate for such purposes without thereby affecting the terms of this Plan as in effect for any other purpose. No such special terms, supplements,
amendments or restatements shall include any provisions that are inconsistent with the terms of this Plan as then in effect unless this Plan could have been amended to eliminate such inconsistency without further approval by the stockholders of the
Company. 
 5.8         Leave of Absence. During leaves of
absence approved by the Company meeting the requirements of Treasury Regulation Section 1.421-1(h)(2) under the Code, a Participant may continue participation in the Plan by making cash payments to the Company on his or her normal payday equal
to his or her authorized payroll deduction.

 ARTICLE 6. 
 GRANT AND EXERCISE OF RIGHTS 

6.1         Grant of Rights. On the Enrollment Date of each Offering
Period, each Eligible Employee participating in such Offering Period shall be granted a right to purchase the maximum number of Shares specified under Section 4.2(b), subject to the limits in Section 5.5, and shall have the right to buy,
on each Purchase Date during such Offering Period (at the applicable Purchase Price), such number of shares of the Company’s Common Stock as is determined by dividing (a) such Participant’s payroll deductions accumulated prior to such
Purchase Date and retained in the Participant’s account as of the Purchase Date, by (b) the applicable Purchase Price. The right shall expire on the last day of the Offering Period. 

6.2         Exercise of Rights. On each Purchase Date, each
Participant’s accumulated payroll deductions and any other additional payments specifically provided for in the applicable Offering Document will be applied to the purchase of whole Shares of the Company, up to the maximum number of shares
permitted pursuant to the terms of the Plan and the applicable Offering Document, at the Purchase Price. No fractional shares shall be issued upon the exercise of rights granted under the Plan, unless the Offering Document specifically provides
otherwise. Any cash in lieu of fractional Shares remaining after the purchase of whole Shares upon exercise of a purchase right will be credited to a Participant’s account and carried forward and applied toward the purchase of whole Shares for
the next following Offering Period. Shares issued pursuant to the Plan may be evidenced in such manner as the Administrator may determine and may be issued in certificated form or issued pursuant to book-entry procedures. 

6.3         Pro Rata Allocation of Shares. If the Administrator determines
that, on a given Purchase Date, the number of Shares with respect to which rights are to be exercised may exceed (a) the number of Shares that were available for issuance under the Plan on the Enrollment Date of the applicable Offering Period,
or (b) the number of Shares available for issuance under the Plan on such Purchase Date, the Administrator may in its sole discretion provide that the Company shall make a pro rata allocation of the Shares available for purchase on such
Enrollment Date or Purchase Date, as applicable, in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all Participants for whom rights to purchase Common Stock are to be exercised
pursuant to this Article 6 on such Purchase Date, and shall either (a) continue all Offering Periods then in effect, or (b) terminate any or all Offering Periods then in effect pursuant to Article 9. The Company may make pro rata
allocation of the shares available on the Enrollment Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under the Plan by the Company’s stockholders
subsequent to such Enrollment Date. The balance of the amount credited to the account of each Participant that has not been applied to the purchase of Shares shall be paid to such Participant in one lump sum in cash as soon as reasonably practicable
after the Purchase Date. 
 6.4         Withholding. At the time
a Participant’s rights under the Plan are exercised, in whole or in part, or at the time some or all of the Common Stock issued under the Plan is disposed of, the Participant must make adequate provision for the Company’s federal, state,
or other tax withholding obligations, if any, that arise upon the exercise of the right or the disposition of the Common Stock. At any time, the Company may, but shall not be obligated to, withhold from the Participant’s compensation the amount
necessary for the Company to meet applicable withholding obligations, including any withholding required to make available to the Company any tax deductions or benefits attributable to sale or early disposition of Common Stock by the Participant.

  
 8 

 6.5         Conditions to
Issuance of Common Stock. The Company shall not be required to issue or deliver any certificate or certificates for, or make any book entries evidencing, Shares purchased upon the exercise of rights under the Plan prior to fulfillment of all of
the following conditions: 
 (a)        The admission of such shares to
listing on all stock exchanges, if any, on which the Common Stock is then listed; and 

(b)        The completion of any registration or other qualification of such
shares under any state or federal law or under the rulings or regulations of the Securities and Exchange Commission or any other governmental regulatory body, that the Administrator shall, in its absolute discretion, deem necessary or advisable; and

 (c)        The obtaining of any approval or other clearance from any
state or federal governmental agency that the Administrator shall, in its absolute discretion, determine to be necessary or advisable; and 
 (d)        The payment to the Company of all amounts that it is required to withhold under federal, state or local law upon exercise of the rights, if any; and

 (e)        The lapse of such reasonable period of time following the
exercise of the rights as the Administrator may from time to time establish for reasons of administrative convenience. 

ARTICLE 7. 

WITHDRAWAL; TERMINATION OF EMPLOYMENT OR ELIGIBILITY 

7.1         Withdrawal. A Participant may withdraw all but not less than
all of the payroll deductions credited to his or her account and not yet used to exercise his or her rights under the Plan at any time by giving written notice to the Company in a form acceptable to the Administrator no later than one week prior to
the end of the Offering Period. All of the Participant’s payroll deductions credited to his or her account during an Offering Period shall be paid to such Participant as soon as reasonably practicable after receipt of notice of withdrawal and
such Participant’s rights for the Offering Period shall be automatically terminated, and no further payroll deductions for the purchase of shares shall be made for such Offering Period. If a Participant withdraws from an Offering Period,
payroll deductions shall not resume at the beginning of the next Offering Period unless the Participant delivers to the Company a new subscription agreement. 
 7.2         Future Participation. A Participant’s withdrawal from an Offering Period shall not have any effect upon his or her eligibility to
participate in any similar plan that may hereafter be adopted by the Company or a Designated Subsidiary or in subsequent Offering Periods that commence after the termination of the Offering Period from which the Participant withdraws. 

7.3         Cessation of Eligibility. Upon a Participant’s ceasing to
be an Eligible Employee for any reason, he or she shall be deemed to have elected to withdraw from the Plan pursuant to this Article 7 and the payroll deductions credited to such Participant’s account during the Offering Period shall be paid to
such Participant or, in the case of his or her death, to the person or persons entitled thereto under Section 12.4, as soon as reasonably practicable, and such Participant’s rights for the Offering Period shall be automatically terminated.

distribution of Company assets to stockholders (other than normal cash dividends), or any other corporate event affecting the Common Stock or the share price of the Common Stock, the Administrator may make such proportionate adjustments, if any, as
the Administrator in its discretion may deem appropriate to reflect such change with respect to (a) the aggregate number and type of Shares (or other securities or property) that may be issued under the Plan (including, but not limited to,
adjustments of the limitations in Section 3.1 and the limitations established in each Offering Document pursuant to Section 4.2 on the maximum number of Shares that may be purchased); (b) the class(es) and number of shares and price
per Share subject to outstanding rights; and (c) the Purchase Price with respect to any outstanding rights.

nonrecurring transactions or events affecting the Company, any affiliate of the Company, or the financial statements of the Company or any affiliate (including without limitation any Change in Control), or of changes in Applicable Law, and whenever
the Administrator determines that such action is appropriate in order to prevent the dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to any right under the Plan, to
facilitate such transactions or events or to give effect to such changes in laws, regulations or principles, the Administrator, in its sole discretion and on such terms and conditions as it deems appropriate, is hereby authorized to take any one or
more of the following actions: 
 (a)        To provide for either
(i) termination of any outstanding right in exchange for an amount of cash, if any, equal to the amount that would have been obtained upon the exercise of such right had such right been currently exercisable or (ii) the replacement of such
outstanding right with other rights or property selected by the Administrator in its sole discretion; 

(b)        To provide that the outstanding rights under the Plan shall be
assumed by the successor or survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by similar rights covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate
adjustments as to the number and kind of shares and prices; and 

(c)        To make adjustments in the number and type of Shares (or other
securities or property) subject to outstanding rights under the Plan and/or in the terms and conditions of outstanding rights and rights that may be granted in the future; 

(d)        To provide that Participants’ accumulated payroll deductions may
be used to purchase Common Stock prior to the next occurring Purchase Date on such date as the Administrator determines in its sole discretion and the Participants’ rights under the ongoing Offering Period(s) terminated; and 

(e)        To provide that all outstanding rights shall terminate without being
exercised. 
 8.3         No Adjustment Under Certain
Circumstances. No adjustment or action described in this Article 8 or in any other provision of the Plan shall be authorized to the extent that such adjustment or action would cause the Plan to fail to satisfy the requirements of
Section 423 of the Code. 
 8.4         No Other Rights.
Except as expressly provided in the Plan, no Participant shall have any rights by reason of any subdivision or consolidation of shares of stock of any class, the payment of any dividend, any increase or decrease in the number of shares of stock of
any class or any dissolution, liquidation, merger, or consolidation of the Company or any other corporation. Except as expressly provided in the Plan or pursuant to action of the Administrator under the Plan, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number of Shares subject to an Award or the grant or exercise price of any Award.

 ARTICLE 9. 
 AMENDMENT, MODIFICATION AND TERMINATION 

9.1        Amendment, Modification and Termination. The Administrator may
amend, suspend or terminate the Plan at any time and from time to time; provided, however, that approval by a vote of the holders of the outstanding shares of the Company’s capital stock entitled to vote shall be required
to amend the Plan to: (a) increase the aggregate number, or change the type, of shares that may be sold pursuant to rights under the Plan under Section 3.1 (other than an adjustment as provided by Article 8); (b) change the
corporations or classes of corporations whose employees may be granted rights under the Plan; or (c) change the Plan in any manner that would cause the Plan to no longer be an “employee stock purchase plan” within the meaning of
Section 423(b) of the Code. 
 9.2        Certain Changes to
Plan. Without stockholder consent and without regard to whether any Participant rights may be considered to have been adversely affected, to the extent permitted by Section 423 of the Code, the Administrator shall be entitled to change the
Offering Periods, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll withholding in excess
of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as the
Administrator determines in its sole discretion advisable that are consistent with the Plan. 

9.3        Actions In the Event of Unfavorable Financial Accounting
Consequences. In the event the Administrator determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable,
modify or amend the Plan to reduce or eliminate such accounting consequence including, but not limited to: 

(a)        altering the Purchase Price for any Offering Period including an
Offering Period underway at the time of the change in Purchase Price; 

(b)        shortening any Offering Period so that the Offering Period ends on a
new Purchase Date, including an Offering Period underway at the time of the Administrator action; and 

(c)        allocating Shares. 

Such modifications or amendments shall not require stockholder approval or the consent of any Participant. 

9.4        Payments Upon Termination of Plan. Upon termination of the
Plan, the balance in each Participant’s Plan account shall be refunded as soon as practicable after such termination, without any interest thereon. 

  
 11 

 ARTICLE 10. 
 TERM OF PLAN 
 The Plan shall be effective on the business
day immediately preceding the date on which the Registration Statement filed with respect to the Plan becomes effective (the “Effective Date”). The effectiveness of the Plan shall be subject to approval of the Plan by the
stockholders of the Company within twelve months following the date the Plan is first approved by the Board. No right may be granted under the Plan prior to such stockholder approval. The Plan shall be in effect until the tenth anniversary of the
date this Plan is first approved by the Board, unless sooner terminated under Article 9. No rights may be granted under the Plan during any period of suspension of the Plan or after termination of the Plan. 

ARTICLE 11. 
 ADMINISTRATION 

11.1        Administrator. The Administrator of the Plan shall be the
Compensation Committee of the Board (or another committee or a subcommittee of the Board to which the Board delegates administration of the Plan) (such committee, the “Committee”), which Committee shall consist solely of two
or more members of the Board each of whom is a “non-employee director” within the meaning of Rule 16b-3 which has been adopted by the Securities and Exchange Commission under the Exchange Act and which Committee is otherwise constituted to
comply with Applicable Law. The Board may abolish the Committee at any time and vest in the Board the administration of the Plan. 
 11.2        Action by the Administrator. A majority of the Administrator shall constitute a quorum. The acts of a majority of the members present at any
meeting at which a quorum is present, and, subject to Applicable Law and the Bylaws of the Company, acts approved in writing by a majority of the Administrator in lieu of a meeting, shall be deemed the acts of the Administrator. Each member of the
Administrator is entitled to, in good faith, rely or act upon any report or other information furnished to that member by any officer or other employee of the Company or any Designated Subsidiary, the Company’s independent certified public
accountants, or any executive compensation consultant or other professional retained by the Company to assist in the administration of the Plan. 
 11.3        Authority of Administrator. The Administrator shall have the power, subject to, and within the limitations of, the express provisions of the
Plan: 
 (a)        To determine when and how rights to purchase Common
Stock shall be granted and the provisions of each offering of such rights (which need not be identical). 

(b)        To designate from time to time which Subsidiaries of the Company
shall be Designated Subsidiaries, which designation may be made without the approval of the stockholders of the Company. 
 (c)        To construe and interpret the Plan and rights granted under it, and to establish, amend and revoke rules and regulations for its administration. The
Administrator, 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. 

(d)        To amend the Plan as provided in Article 9. 

  
 12 

 (e)        Generally, to exercise
such powers and to perform such acts as the Administrator deems necessary or expedient to promote the best interests of the Company and its Subsidiaries and to carry out the intent that the Plan be treated as an “employee stock purchase
plan” within the meaning of Section 423 of the Code. 

11.4        Decisions Binding. The Administrator’s interpretation of
the Plan, any rights granted pursuant to the Plan, any subscription agreement and all decisions and determinations by the Administrator with respect to the Plan are final, binding, and conclusive on all parties. 

ARTICLE 12. 
 MISCELLANEOUS 

12.1        Restriction upon Assignment. A right granted under the Plan
shall not be transferable other than by will or the applicable laws of descent and distribution, and is exercisable during the Participant’s lifetime only by the Participant. Except as provided in Section 12.4 hereof, a right under the
Plan may not be exercised to any extent except by the Participant. The Company shall not recognize and shall be under no duty to recognize any assignment or alienation of the Participant’s interest in the Plan, the Participant’s rights
under the Plan or any rights thereunder. 
 12.2        Rights as a
Stockholder. With respect to Shares subject to a right granted under the Plan, a Participant shall not be deemed to be a stockholder of the Company, and the Participant shall not have any of the rights or privileges of a stockholder, until such
shares have been issued to the Participant or his or her nominee following exercise of the Participant’s rights under the Plan. No adjustments shall be made for dividends (ordinary or extraordinary, whether in cash securities, or other
property) or distribution or other rights for which the record date occurs prior to the date of such issuance, except as otherwise expressly provided herein. 
 12.3        Interest. No interest shall accrue on the payroll deductions or lump sum contributions of a Participant under the Plan. 

12.4        Designation of Beneficiary. 

(a)        A Participant may, in the manner determined by the Administrator,
file a written designation of a beneficiary who is to receive any shares and cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death subsequent to a Purchase Date on which the Participant’s
rights are exercised but prior to delivery to such Participant of such shares and cash. In addition, a Participant may file a written designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the
event of such Participant’s death prior to exercise of the Participant’s rights under the Plan. If the Participant is married and resides in a community property state, a designation of a person other than the Participant’s spouse as
his or her beneficiary shall not be effective without the prior written consent of the Participant’s spouse. 
 (b)        Such designation of beneficiary may be changed by the Participant at any time by written notice to the Company. In the event of the death of a
Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company shall deliver such shares and/or cash to the executor or administrator of the estate of the
Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the
Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 

  
 13 

 12.5        Notices. All
notices or other communications by a Participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the
Company for the receipt thereof. 
 12.6        Equal Rights and
Privileges. Subject to Section 5.7, all Eligible Employees of the Company or any Designated Subsidiary will have equal rights and privileges under this Plan so that this Plan qualifies as an “employee stock purchase plan” within
the meaning of Section 423 of the Code. Subject to Section 5.7, any provision of this Plan that is inconsistent with Section 423 of the Code will, without further act or amendment by the Company, the Board or the Administrator, be
reformed to comply with the equal rights and privileges requirement of Section 423 of the Code. 

12.7        Use of Funds. All payroll deductions received or held by the
Company under the Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions. 
 12.8        Reports. Statements of account shall be given to participating Employees at least annually, which statements shall set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the remaining cash balance, if any. 

12.9        No Employment Rights. Nothing in the Plan shall be construed
to give any person (including any Eligible Employee or Participant) the right to remain in the employ of the Company or any Parent or Subsidiary or to affect the right of the Company or any Parent or Subsidiary to terminate the employment of any
person (including any Eligible Employee or Participant) at any time, with or without cause. 

12.10        Notice of Disposition of Shares. Each Participant shall give
prompt notice to the Company of any disposition or other transfer of any shares of stock purchased upon exercise of a right under the Plan if such disposition or transfer is made: (a) within two years from the Enrollment Date of the Offering
Period in which the shares were purchased or (b) within one year after the Purchase Date on which such shares were purchased. Such notice shall specify the date of such disposition or other transfer and the amount realized, in cash, other
property, assumption of indebtedness or other consideration, by the Participant in such disposition or other transfer. 
 12.11        Governing Law. The Plan and any agreements hereunder shall be administered, interpreted and enforced under the internal laws of the State of
Delaware without regard to conflicts of laws thereof or of any other jurisdiction. 

12.12        Electronic Forms. To the extent permitted by applicable state
law and in the discretion of the Administrator, an Eligible Employee may submit any form or notice as set forth herein by means of an electronic form approved by the Administrator. Before the commencement of an Offering Period, the Administrator
shall prescribe the time limits within which any such electronic form shall be submitted to the Administrator with respect to such Offering Period in order to be a valid election. 

  
 14EX-10.7

 Exhibit 10.7 
 May 22, 2013 
 Dear Dave: 
 Evoke Pharma, Inc. (the “Company”) values your future contributions. This letter agreement amends and restates (the “Amended and Restated Letter Agreement”)
a letter agreement entered into by you with the Company on March 28, 2012, and describes a retention program the Company has established for each of its employees. 
 1. Retention Events. Upon the first to occur of (a) a Change of Control (as defined below), or (b) an Equity Financing (as defined below) (each such event, a “Retention
Event”), you will be eligible to receive a payment(s) in the amount of $225,000.00 (the “Retention Amount”). In the event the Retention Event is a Change of Control, the Retention Amount will be paid to you in
cash on the closing date of such Change of Control to recognize the support required to assist in transferring trade secrets and ongoing project management beyond the date of termination. In the event the Retention Event is an Equity Financing, the
Retention Amount will be paid to you in cash in 3 equal installments over the 3 months following the consummation of the Equity Financing to ensure a heightened level of support required to accelerate corporate development. Subject to paragraph 2
below, your eligibility for receipt of the foregoing payment(s) is contingent upon your continued employment through the applicable payment date(s). For purposes of this Amended and Restated Letter Agreement, the term “Change of
Control” shall have the meaning given to such term in your Amended and Restated Employment Agreement dated as of August 12, 2008, with the Company (the “Employment Agreement”) as in effect on the date hereof. For
purposes of this Amended and Restated Letter Agreement, the term “Equity Financing” shall mean the consummation of a public or private equity financing in which investors purchase shares of the Company’s
common or preferred stock. 
 2. Effect of Termination of Employment. If you voluntarily terminate your employment with
the Company without Good Reason (as defined below) or your employment terminates as a result of your death or disability (which for these purposes will mean that you are eligible for benefits under the Company’s long-term disability plan) or if
the Company terminates your employment for Cause (as defined below), in each case prior to the date on which you have received the full Retention Amount, then you will forfeit any right you may have to receive any unpaid portion of the Retention
Amount under this Amended and Restated Letter Agreement. For purposes of this Amended and Restated Letter Agreement, the terms “Cause” and “Good Reason” shall have the meanings given to such terms in
the Employment Agreement (provided that clauses (vi) and (vii) of the definition of Good Reason shall not apply for purposes of this Amended and Restated Letter Agreement, you must give the Company notice of the initial occurrence of the event(s)
giving rise to Good Reason within thirty days after such occurrence and your resignation for Good Reason must occur within ninety days following the initial occurrence of the event giving rise to Good Reason). 

If, however, the Company terminates your employment without Cause or you resign for Good Reason prior to the date on which you have
received the full Retention Amount, and without regard to whether a Retention Event has occurred prior to the date of termination, then you will be entitled to receive any unpaid portion of the Retention Amount on the date that is sixty days
following your date of termination. As a condition to your receipt of the unpaid portion of the Retention Amount following your termination of employment without Cause or resignation for Good Reason, you will be required to execute a release (the
“Release”) in a form acceptable to the Company. Such Release shall specifically relate to all of your rights and claims in existence at the time of such execution and shall confirm your obligations under the Company’s
standard form of proprietary information and inventions agreement. It is understood that, as specified in the applicable Release, you will have a certain number of calendar days to consider whether to execute such Release, and you may

 
revoke such Release within seven calendar days after execution. In the event your Release does not become effective within the sixty day period following your date of
termination, you will forfeit your right to receive the unpaid portion of the Retention Amount. 
 The unpaid portion of the
Retention Amount will be paid to you in cash within five days following the effective date of your Release. 
 3.
Relationship to Other Compensation. The Retention Amount described herein is independent of all other compensation. You will also remain eligible for all benefits under the Employment Agreement. 

4. Tax and Other Deductions. The Retention Amount will be paid, less federal, state and local taxes required to be withheld
by the Company. 
 5. Employment at Will. This Amended and Restated Letter Agreement does not affect your employment
relationship with the Company; that is, employment with the Company remains at-will unless otherwise expressly agreed in a separate written contract between you and the Company. 

6. Section 409A of the Internal Revenue Code. To the maximum extent permitted by applicable law, the amounts payable
pursuant to this Amended and Restated Letter Agreement shall be made in reliance upon Treasury Regulation Section 1.409A-1(b)(4) (with respect to short-term deferrals). To the extent the Retention Amount payable under this Amended and Restated
Letter Agreement are subject to Section 409A of the Internal Revenue Code, this Amended and Restated Letter Agreement shall be interpreted, construed and administered in a manner that satisfies the requirements of Sections 409A(a)(2), (3) and (4) of
the Internal Revenue Code and the Treasury Regulations thereunder. 
 7. Miscellaneous. This Amended and Restated Letter
Agreement shall be binding upon and inure to the benefit of the successors of the Company. This Amended and Restated Letter Agreement will not give any rights or remedies to any person other than the undersigned employee and the Company and its
successors. This Amended and Restated Letter Agreement will be governed by the laws of the State of California, excluding any that mandate the use of another jurisdiction’s laws. This Amended and Restated Letter Agreement may only be amended
with the written consent of the Chairman of the Board of the Company and you. You shall have no rights under this Amended and Restated Letter Agreement other than as an unsecured general creditor of the Company. 

Sincerely,
