4. Administration of the Plan. 

(a) Administrator. The Plan shall be administered by the Board or a Committee appointed by the Board, which Committee shall be
constituted to comply with Applicable Laws. 
 (b)
Powers of the Administrator. Subject to the provisions of the Plan and, in the case of a Committee, the specific duties delegated by the Board to such Committee, and subject to the
approval of any relevant authorities, the Administrator shall have the authority in its discretion: 
 (i) to determine the Fair Market
Value;

Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined. All elections by Optionees to have Shares withheld for this purpose shall be made in such form and under such conditions as the
Administrator may deem necessary or advisable; and 

  
 -4- 

 (ix) to construe and interpret the terms of the Plan and Options granted pursuant to the Plan.

 (c) Effect of Administrator’s Decision. All decisions, determinations and interpretations of the Administrator
shall be final and binding on all Optionees. 
 5. Eligibility. Nonstatutory Stock Options and Stock Purchase Rights may be granted to
Service Providers. Incentive Stock Options may be granted only to Employees. 
 6. Limitations. 

(a) Incentive Stock Option Limit. Each Option shall be designated in the Option Agreement as either an Incentive Stock Option or a
Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Optionee during any
calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options shall be taken into account in
the order in which they were granted. The Fair Market Value of the Shares shall be determined as of the time the Option with respect to such Shares is granted. 

(b) At-Will Employment. Neither the Plan nor any Option or Stock Purchase Right shall confer upon any Optionee any right with respect to
continuing the Optionee’s relationship as a Service Provider with the Company, nor shall it interfere in any way with his or her right or the Company’s right to terminate such relationship at any time, with or without cause, and with or
without notice. 
 7. Term of Plan. Subject to stockholder approval in accordance with Section 19, the Plan shall become
effective upon its adoption by the Board. Unless sooner terminated under Section 15, it shall continue in effect for a term of ten (10) years from the later of (i) the effective date of the Plan, or (ii) the earlier of the most recent
Board or stockholder approval of an increase in the number of Shares reserved for issuance under the Plan. 
 8. Term of Option. The
term of each Option shall be stated in the Option Agreement; provided, however, that the term shall be no more than ten (10) years from the date of grant thereof. In the case of an Incentive Stock Option granted to an Optionee who, at the time
the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Option shall be five (5) years from the date of grant or such
shorter term as may be provided in the Option Agreement. 
 9. Option Exercise Price and Consideration. 

(a) Exercise Price. The per share exercise price for the Shares to be issued upon exercise of an Option shall be such price as is
determined by the Administrator, but shall be subject to the following: 
 (i) In the case of an Incentive Stock Option 

  
 -5- 

 (A) granted to an Employee who, at the time of grant of such Option, owns stock representing
more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant. 

(B) granted to any other Employee, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of
grant. 
 (ii) In the case of a Nonstatutory Stock Option 

(A) granted to a Service Provider who, at the time of grant of such Option, owns stock representing more than ten percent (10%) of the voting
power of all classes of stock of the Company or any Parent or Subsidiary, the exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant. 

(B) granted to any other Service Provider, the per Share exercise price shall be no less than 85% of the Fair Market Value per Share on the
date of grant. 
 (iii) Notwithstanding the foregoing, Options may be granted with a per Share exercise price other than as required above
in accordance with and pursuant to a transaction described in Section 424 of the Code. 
 (b) Forms of Consideration. The
consideration to be paid for the Shares to be issued upon exercise of an Option, 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).
Such consideration may consist of, without limitation, (1) cash, (2) check, (3) promissory note, (4) other Shares, provided Shares acquired directly from the Company (x) have been owned by the Optionee, and not subject to a
substantial risk of forfeiture, for more than six months on the date of surrender, and (y) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option shall be exercised,
(5) consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan, or (6) any combination of the foregoing methods of payment. In making its determination as to the type of
consideration to accept, the Administrator shall consider if acceptance of such consideration may be reasonably expected to benefit the Company. 

10. Exercise of Option. 

(a) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder shall be exercisable according to the terms
hereof at such times and under such conditions as determined by the Administrator and set forth in the Option Agreement. An Option may not be exercised for a fraction of a Share. Except in the case of Options granted to officers, Directors and
Consultants, Options shall become exercisable at a rate of no less than 20% per year over five (5) years from the date the Options are granted. 

An Option shall be deemed exercised when the Company receives (i) written or electronic notice of exercise (in accordance with the
Option Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised. Full payment may consist of any consideration and method of payment authorized by the

  
 -6- 

 
Administrator and permitted by the Option Agreement and the Plan. Shares issued upon exercise of an Option shall be issued in the name of the Optionee or, if requested by the Optionee, in the
name of the Optionee and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other
rights as a stockholder shall exist with respect to the Shares, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend
or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 13 of the Plan. 

Exercise of an Option in any manner shall result in a decrease in the number of Shares thereafter available, both for purposes of the Plan
and for sale under the Option, by the number of Shares as to which the Option is exercised. 
 (b) Termination of Relationship
as a Service Provider. If an Optionee ceases to be a Service Provider, such Optionee may exercise his or her Option within thirty (30) days of termination, or such longer period of time as specified in the Option Agreement, to the extent that
the Option is vested on the date of termination (but in no event later than the expiration of the term of the Option as set forth in the Option Agreement). Unless the Administrator provides otherwise, if on the date of termination the Optionee is
not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified by the Administrator, the
Option shall terminate, and the Shares covered by such Option shall revert to the Plan. 
 (c) Disability of Optionee. If an Optionee
ceases to be a Service Provider as a result of the Optionee’s Disability, the Optionee may exercise his or her Option within six (6) months of termination, or such longer period of time as specified in the Option Agreement, to the extent the
Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement). Unless the Administrator provides otherwise, if on the date of termination the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan. 
 (d)
Death of Optionee. If an Optionee dies while a Service Provider, the Option may be exercised within six (6) months following Optionee’s death, or such longer period of time as specified in the Option
Agreement, to the extent that the Option is vested on the date of death (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement) by the Optionee’s designated beneficiary, provided such
beneficiary has been designated prior to Optionee’s death in a form acceptable to the Administrator. If no such beneficiary has been designated by the Optionee, then such Option may be exercised by the personal representative of the
Optionee’s estate or by the person(s) to whom the Option is transferred pursuant to the Optionee’s will or in accordance with the laws of descent and distribution. If, at the time of death, the Optionee is not vested as to his or her
entire Option, the Shares covered by the unvested portion of the Option shall immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan. 

  
 -7- 

 (e) Leaves of Absence. 

(i) Unless the Administrator provides otherwise, vesting of Options granted hereunder shall be suspended during any unpaid leave of absence.

 (ii) A Service Provider shall not cease to be an Employee in the case of (A) any leave of absence approved by the Company or
(B) transfers between locations of the Company or between the Company, its Parent, any Subsidiary, or any successor. 
 (iii) For
purposes of Incentive Stock Options, no such leave may exceed ninety (90) days, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment upon expiration of a leave of absence approved by the Company is
not so guaranteed, then three (3) months following the 91st day of such leave, any Incentive Stock Option held by the Optionee shall cease to be treated as an Incentive Stock Option and shall be treated for tax purposes as a Nonstatutory Stock
Option. 
 11. Stock Purchase Rights. 

(a) Rights to Purchase. Stock Purchase Rights may be issued either alone, in addition to, or in tandem with other awards granted under
the Plan and/or cash awards made outside of the Plan. After the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall advise the offeree in writing or electronically of the terms, conditions and restrictions
related to the offer, including the number of Shares that such person shall be entitled to purchase, the price to be paid, and the time within which such person must accept such offer. The terms of the offer shall comply in all respects with
Section 260.140.42 of Title 10 of the California Code of Regulations. The offer shall be accepted by execution of a Restricted Stock Purchase Agreement in the form determined by the Administrator. 

(b) Repurchase Option. Unless the Administrator determines otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable within 90 days of the voluntary or involuntary termination of the purchaser’s service with the Company for any reason (including death or disability). Unless the Administrator provides otherwise, the purchase price
for Shares repurchased pursuant to the Restricted Stock Purchase Agreement shall be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse at
such rate as the Administrator may determine. Except with respect to Shares purchased by officers, Directors and Consultants, the repurchase option shall in no case lapse at a rate of less than 20% per year over five (5) years from the date of
purchase. 
 (c) Other Provisions. The Restricted Stock Purchase Agreement shall contain such other terms, provisions and conditions
not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. 
 (d) Rights as a Stockholder. Once
the Stock Purchase Right is exercised, the purchaser shall have rights equivalent to those of a stockholder and shall be a stockholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No
adjustment shall be made for a dividend or other right for which the record date is prior to the date the Stock Purchase Right is exercised, except as provided in Section 13 of the Plan. 

  
 -8- 

 12. Limited Transferability of Options and Stock Purchase Rights. Unless
determined otherwise by the Administrator, Options and Stock Purchase Rights may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or the laws of descent and distribution, and may be exercised
during the lifetime of the Optionee, only by the Optionee. If the Administrator in its sole discretion makes an Option or Stock Purchase Right transferable, such Option or Stock Purchase Right may only be transferred (i) by will, (ii) by the laws of
descent and distribution, or (iii) to family members (within the meaning of Rule 701 of the Securities Act) through gifts or domestic relations orders, as permitted by Rule 701 of the Securities Act. 

13. Adjustments; Dissolution or Liquidation; Merger or Change in Control. 

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or other
property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure
of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, may (in its sole discretion) adjust the number and class
of Shares that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Option or Stock Purchase Right; provided, however, that the Administrator shall make such adjustments to the extent required by
Section 25102(o) of the California Corporations Code. 
 (b) Dissolution or Liquidation. In the event of the proposed dissolution
or liquidation of the Company, the Administrator shall notify each Optionee as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Option or Stock Purchase Right will
terminate immediately prior to the consummation of such proposed action. 
 (c) Merger or Change in Control. In the event of a merger
of the Company with or into another corporation, or a Change in Control, each outstanding Option and Stock Purchase Right may be assumed or an equivalent option, stock purchase right or other security of equal value, as determined by the Board,
substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation in a merger or Change in Control does not assume or substitute for the Option or Stock Purchase Right, any
unexercised portion of such Option or Stock Purchase Right shall terminate and cease to be outstanding effective as of the time of consummation of the Change in Control. Notwithstanding the above, the Board may, in its sole discretion, provide
for the acceleration of the exercisability and vesting in connection with a Change in Control of any or all outstanding Options and Stock Purchase Rights and shares acquired upon the exercise thereof subject to conditions and to such extent as the
Board shall determine. If an Option or Stock Purchase Right becomes fully vested and exercisable pursuant to the above in the event of a merger or Change in Control, the Administrator shall notify the Optionee in writing or electronically that
the Option or Stock Purchase Right shall be fully exercisable for a period of time as determined by the Administrator (contingent upon the consummation of the Change in Control), and the Option or Stock Purchase Right shall terminate upon expiration
of such period. For the purposes of this paragraph, the Option or Stock Purchase Right shall be considered assumed if, following the merger or Change in Control, the option or right confers the right to purchase or

  
 -9- 

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

14. Time of Granting Options and Stock Purchase Rights. The date of grant of an Option or Stock Purchase Right shall, for all
purposes, be the date on which the Administrator makes the determination granting such Option or Stock Purchase Right, or such later date as is determined by the Administrator. Notice of the determination shall be given to each Service Provider to
whom an Option or Stock Purchase Right is so granted within a reasonable time after the date of such grant. 
 15.
Amendment and Termination of the Plan. 
 (a) Amendment and Termination. The Board may at any time
amend, alter, suspend or terminate the Plan. 
 (b) Stockholder Approval. The Board shall obtain stockholder approval of any Plan
amendment to the extent necessary and desirable to comply with Applicable Laws. 
 (c) Effect of Amendment or Termination. No
amendment, alteration, suspension or termination of the Plan shall impair the rights of any Optionee, unless mutually agreed otherwise between the Optionee and the Administrator, which agreement must be in writing and signed by the Optionee and the
Company. Nothwithstanding anything herein to the contrary, the Board may, in its sole and absolute discretion and without the consent of any Optionee, amend the Plan and any Option Agreement or Restricted Stock Purchase Agreement, to take effect
retroactively or otherwise, as it deems necessary or advisable for the purpose of conforming the Plan or such agreement to any Applicable Laws, including, but not limited to, Section 409A of the Code. Termination of the Plan shall not affect
the Administrator’s ability to exercise the powers granted to it hereunder with respect to Options granted under the Plan prior to the date of such termination. 

16. Conditions Upon Issuance of Shares. 

(a) Legal Compliance. Shares shall not be issued pursuant to the exercise of an Option or Stock Purchase Right unless the exercise of
such Option or Stock Purchase Right and the issuance and delivery of such Shares shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance. 

(b) Investment Representations. As a condition to the exercise of an Option or Stock Purchase Right, the Administrator may require the person
exercising such Option or Stock Purchase Right 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. 

  
 -10- 

 17. Inability to Obtain Authority. 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. 
 18. Reservation of Shares. The Company,
during the term of this Plan, shall at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 

19. Stockholder Approval. The Plan shall be subject to approval by the stockholders of the Company within twelve (12) months after
the date the Plan is adopted. Such stockholder approval shall be obtained in the degree and manner required under Applicable Laws. 
 20.
Information to Optionees. The Company shall provide to each Optionee and to each individual who acquires Shares pursuant to the Plan, not less frequently than annually during the period such Optionee has one or more Options or Stock Purchase
Rights outstanding, and, in the case of an individual who acquires Shares pursuant to the Plan, during the period such individual owns such Shares, copies of annual financial statements. The Company shall not be required to provide such statements
to key employees whose duties in connection with the Company assure their access to equivalent information.

 <vesting_schedule> 

Termination Period: 
 This
Option shall be exercisable for three (3) months after Optionee ceases to be a Service Provider, unless such termination is due to Optionee’s death or Disability, in which case this Option shall be exercisable for one (1) year after Optionee

	II.	AGREEMENT 

 1. Grant of Option. The Plan Administrator of the Company
hereby grants to the Optionee named in the Notice of Grant (the “Optionee”), an option (the “Option”) to purchase the number of Shares set forth in the Notice of Grant, at the exercise price per Share set forth in
the Notice of Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan, which is incorporated herein by reference. Subject to Section 15(c) of the Plan, in the event of a conflict between the terms

Section 422(d), this Option shall be treated as a Nonstatutory Stock Option (“NSO”). Further, if for any reason this Option (or portion thereof) shall not qualify as an ISO, then, to the extent of such nonqualification,
such Option (or portion thereof) shall be regarded as a NSO granted under the Plan. In no event shall the Administrator, the Company or any Parent or Subsidiary or any of their respective employees or directors have any liability to Optionee
(or any other person) due to the failure of the Option to qualify for any reason as an ISO. 
 2. Exercise of Option. 

(a) Right to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the
Notice of Grant and with the applicable provisions of the Plan and this Option Agreement. 
 (b) Method of Exercise. This Option
shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which shall state
the election to exercise the Option, the number of Shares with respect to which the Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment
of the aggregate Exercise Price as to all Exercised Shares, together with any applicable tax withholding. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the
aggregate Exercise Price, together with any applicable tax withholding. 
 No Shares shall be issued pursuant to the exercise of an Option
unless such issuance and such exercise comply with Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to the Optionee on the date on which the Option is exercised with respect to such
Shares. 
 3. Optionee’s Representations. In the event the Shares have not been registered under the Securities Act of 1933,
as amended, at the time this Option is exercised, the Optionee shall, if required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form

 4. Lock-Up Period. Optionee hereby agrees that Optionee shall not offer, pledge,
sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Stock (or other
securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other securities) of the Company held by Optionee
(other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred eighty (180) days following the effective date of any
registration statement of the Company filed under the Securities Act (or such other period as may be requested by the Company or the underwriters to accommodate regulatory restrictions on (i) the publication or other distribution of research
reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto). 

Optionee agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter which are
consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, Optionee shall
provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a registration statement
filed under the Securities Act. The obligations described in this Section 4 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a
registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other
securities) subject to the foregoing restriction until the end of said one hundred eighty (180) day (or other) period. Optionee agrees that any transferee of the Option or shares acquired pursuant to the Option shall be bound by this
Section 4. 
 5. Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a
combination thereof, at the election of the Optionee: 
 (a) cash or check; 

(b) consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or 

(c) surrender of other Shares which (i) shall be valued at its Fair Market Value on the date of exercise, and (ii) must be owned free and clear
of any liens, claims, encumbrances or security interests, if accepting such Shares, in the sole discretion of the Administrator, shall not result in any adverse accounting consequences to the Company. 

6. Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been approved by the stockholders of
the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any Applicable Law. 

  
 -3- 

 7. Non-Transferability of Option. This Option may not be transferred in any manner
otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Optionee only by Optionee. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs,
successors and assigns of the Optionee. 
 8. Term of Option. This Option may be exercised only within the term set out in the
Notice of Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Option Agreement. 
 9. Tax
Obligations. 
 (a) Withholding Taxes. Optionee agrees to make appropriate arrangements with the Company (or the Parent or
Subsidiary employing or retaining Optionee) for the satisfaction of all Federal, state, local and foreign income and employment tax withholding requirements applicable to the Option exercise. Optionee acknowledges and agrees that the Company
may refuse to honor the exercise and refuse to deliver Shares if such withholding amounts are not delivered at the time of exercise. 
 (b)
Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (i) the
date two years after the Date of Grant, or (ii) the date one year after the date of exercise, the Optionee shall immediately notify the Company in writing of such disposition. Optionee agrees that Optionee may be subject to income tax
withholding by the Company on the compensation income recognized by the Optionee. 
 (c) Code Section 409A. Under Code Section
409A, an Option that vests after December 31, 2004 (or that vested on or prior to such date but which was materially modified after October 3, 2004) that was granted with a per Share exercise price that is determined by the Internal Revenue Service
(the “IRS”) to be less than the Fair Market Value of a Share on the date of grant (a “discount option”) may be considered “deferred compensation.” An Option that is a “discount option” may result in (i)
income recognition by Optionee prior to the exercise of the Option, (ii) an additional twenty percent (20%) federal income tax, and (iii) potential penalty and interest charges. The “discount option” may also result in additional
state income, penalty and interest tax to the Optionee. Optionee acknowledges that the Company cannot and has not guaranteed that the IRS will agree that the per Share exercise price of this Option equals or exceeds the Fair Market Value of a
Share on the date of grant in a later examination. Optionee agrees that if the IRS determines that the Option was granted with a per Share exercise price that was less than the Fair Market Value of a Share on the date of grant, Optionee shall
be solely responsible for Optionee’s costs related to such a determination. 
 10. Entire Agreement; Governing Law. The Plan
is incorporated herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the
Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company and Optionee. This Option Agreement is governed by the internal
substantive laws but not the choice of law rules of California. 

  
 -4- 

 11. Electronic Acceptance of Agreement and Electronic Delivery. Electronic Acceptance of
Agreement and Electronic Delivery. By the Optionee’s electronic acceptance of this Option, the Optionee and the Company agree that this Option is granted under and governed by the terms and conditions of the Plan, the Notice of Grant and the
Option Agreement. By accepting this Option, the Optionee consents to electronic delivery of all notifications and documents associated with the Option and agrees to participate in the Plan through any on-line or electronic system established and
maintained by the Company or a third party designated by the Company. 
 12. No Guarantee of Continued Service. OPTIONEE
ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING OPTIONEE) AND NOT THROUGH
THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER. OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE
AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH OPTIONEE’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE PARENT OR SUBSIDIARY
EMPLOYING OR RETAINING OPTIONEE) TO TERMINATE OPTIONEE’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

San Francisco, CA 94108 
 Attention: Chief Financial Officer

 1. Exercise of Option. Effective as of today,
                    ,         , the undersigned (“Optionee”) hereby elects to exercise
Optionee’s option to purchase              shares of the Common Stock (the “Shares”) of MuleSoft, Inc. (the “Company”) under and pursuant to the
2006 Stock Plan (the “Plan”) and the Stock Option Agreement dated <award_date> (the “Option Agreement”). 

2. Delivery of Payment. Optionee herewith delivers to the Company the full purchase price of the Shares, as set forth in the Option
Agreement, and any and all withholding taxes due in connection with the exercise of the Option. 
 3. Representations of
Optionee. Optionee acknowledges that Optionee has received, read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms and conditions. 

4. Rights as Stockholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of
a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Shares shall be issued
to the Optionee as soon as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for which the record date is prior to the date of issuance except as
provided in Section 13 of the Plan. 
 5. Company’s Right of First Refusal. Before any Shares held by
Optionee or any transferee (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this Section 5 (the “Right of First Refusal”). 

(a) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the
“Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed Transferee”); (iii) the
number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Shares (the “Offered Price”), and the Holder shall offer the
Shares at the Offered Price to the Company or its assignee(s). 

 (b) Exercise of Right of First Refusal. At any time within thirty (30) days
after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at
the purchase price determined in accordance with subsection (c) below. 
 (c) Purchase Price. The purchase price
(“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section 5 shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 
 (d) Payment. Payment of the
Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the
assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice. 

(e) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee
are not purchased by the Company and/or its assignee(s) as provided in this Section 5, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price; provided that such
sale or other transfer is consummated within 120 days after the date of the Notice, that any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the
provisions of this Section 5 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be
given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 

(f) Exception for Certain Family Transfers. Anything to the contrary contained in this Section 5 notwithstanding, the transfer
of any or all of the Shares during the Optionee’s lifetime or on the Optionee’s death by will or intestacy to the Optionee’s immediate family or a trust for the benefit of the Optionee’s immediate family shall be exempt from the
provisions of this Section 5. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and
hold the Shares so transferred subject to the provisions of this Section 5, and there shall be no further transfer of such Shares except in accordance with the terms of this Section 5. 

(g) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon the earlier of (i) the
first sale of Common Stock of the Company to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 

  
 -2- 

 6. Tax Consultation. Optionee understands that Optionee may suffer adverse tax
consequences as a result of Optionee’s purchase or disposition of the Shares. Optionee represents that Optionee has consulted with any tax consultants Optionee deems advisable in connection with the purchase or disposition of the Shares
and that Optionee is not relying on the Company for any tax advice. 
 7. Restrictive Legends and Stop-Transfer Orders. 

(a) Legends. Optionee understands and agrees that the Company shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD
OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COMPANY COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST REFUSAL HELD BY
THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT OF FIRST
REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER FOR
A PERIOD OF TIME FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES SET FORTH IN AN AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF BY
THE HOLDER PRIOR TO THE EXPIRATION OF SUCH PERIOD WITHOUT THE CONSENT OF THE COMPANY OR THE MANAGING UNDERWRITER. 
 (b) Stop-Transfer
Notices. Optionee agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company
transfers its own securities, it may make appropriate notations to the same effect in its own records. 
 (c) Refusal to
Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Exercise Notice or (ii) to treat as owner of such
Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred.

 8. Successors and Assigns. The Company may assign any of its rights under this
Exercise Notice to single or multiple assignees, and this Exercise Notice shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Exercise Notice shall be binding
upon Optionee and his or her heirs, executors, administrators, successors and assigns. 
 9. Interpretation. Any dispute
regarding the interpretation of this Exercise Notice shall be submitted by Optionee or by the Company forthwith to the Administrator which shall review such dispute at its next regular meeting. The resolution of such a dispute by the
Administrator shall be final and binding on all parties. 
 10. Governing Law; Severability. This Exercise Notice is governed by
the internal substantive laws but not the choice of law rules, of California. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Exercise Notice will
continue in full force and effect. 
 11. Entire Agreement. The Plan and Option Agreement are incorporated herein by
reference. This Exercise Notice, the Plan, the Option Agreement and the Investment Representation Statement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior
undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company and Optionee.

INVESTMENT REPRESENTATION STATEMENT 
  

			
	OPTIONEE:	  	<first_name> <last_name>
		
	COMPANY:	  	MULESOFT, INC.
		
	SECURITY:	  	COMMON STOCK
		
	 GRANT ID:
	  	 <award_id>

		
	AMOUNT:	  	
		
	DATE:	  	

 In connection with the purchase of the above-listed Securities, the undersigned Optionee represents to the
Company the following: 
 (a) Optionee is aware of the Company’s business affairs and financial condition and has acquired sufficient
information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Optionee is acquiring these Securities for investment for Optionee’s own account only and not with a view to, or for resale in
connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 

(b) Optionee acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have
not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Optionee’s investment intent as expressed herein. In this connection,
Optionee understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Optionee’s representation was predicated solely upon a present intention to hold these Securities for
the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the future. Optionee
further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Optionee further acknowledges and understands that the
Company is under no obligation to register the Securities. Optionee understands that the certificate evidencing the Securities will be imprinted with any legend required under applicable state securities laws. 

(c) Optionee is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in
substance, permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if
the issuer qualifies under Rule 701 at the 

 
time of the grant of the Option to the Optionee, the exercise will be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting
requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities exempt under Rule 701 may be resold, subject
to the satisfaction of the applicable conditions specified by Rule 144, including in the case of affiliates (1) the availability of certain public information about the Company, (2) the amount of Securities being sold during any three
(3) month period not exceeding specified limitations, (3) the resale being made in an unsolicited “broker’s transaction”, transactions directly with a “market maker” or “riskless principal transactions” (as
those terms are defined under the Securities Exchange Act of 1934) and (4) the timely filing of a Form 144, if applicable. 
 In
the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which may require (i) the
availability of current public information about the Company; (ii) the resale to occur more than a specified period after the purchase and full payment (within the meaning of Rule 144) for the Securities; and (iii) in the case of the
sale of Securities by an affiliate, the satisfaction of the conditions set forth in sections (2), (3) and (4) of the paragraph immediately above. 

(d) Optionee further understands that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration
under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has
expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 will have a substantial burden of proof in establishing that an exemption from
registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Optionee understands that no assurances can be given that any such other
registration exemption will be available in such event.

 This Option shall be exercisable, in whole or in part, according to the following vesting schedule,
subject to Optionee continuing to be a Service Provider on such dates: 
 <vesting_schedule> 

Termination Period: 

This Option shall be exercisable for three (3) months after Optionee ceases to be a Service Provider, unless such termination is due to
Optionee’s death or Disability, in which case this Option shall be exercisable for one (1) year after Optionee ceases to be a Service Provider. Notwithstanding the foregoing sentence, in no event may this Option be exercised after the
Term/Expiration Date as provided above and this Option may be subject to earlier termination as provided in Section 13 of the Plan. 

	II.	AGREEMENT 

 1. Grant of Option. The Administrator of the Company hereby
grants to the Optionee named in the Notice of Grant in Part I of this Agreement (the “Optionee”), an option (the “Option”) to purchase the number of Shares set forth in the Notice of Grant, at the exercise price per Share set
forth in the Notice of Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan, which is incorporated herein by reference. Subject to Section 15(c) of the Plan, in the event of a conflict between the
terms and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall prevail. 
 If designated in the
Notice of Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the $100,000 rule of Code Section
422(d), this Option shall be treated as a Nonstatutory Stock Option (“NSO”). 
 2. Exercise of Option. This Option
shall be exercisable during its term in accordance with the provisions of Section 10 of the Plan as follows: 
 (a) Right to
Exercise. 
 (i) Subject to subsections 2(a)(ii) and 2(a)(iii) below, this Option shall be exercisable cumulatively according to
the vesting schedule set forth in the Notice of Grant. Alternatively, at the election of the Optionee, this Option may be exercised in whole or in part at any time as to Shares that have not yet vested. Vested Shares shall not be subject
to the Company’s repurchase right (as set forth in the Restricted Stock Purchase Agreement, attached hereto as Exhibit C-1). 

(ii) As a condition to exercising this Option for unvested Shares, the Optionee shall execute the Restricted Stock Purchase Agreement. 

(iii) This Option may not be exercised for a fraction of a Share. 

(b) Method of Exercise. This Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A
(the “Exercise Notice”), which shall state the election to exercise the Option, the number of Shares with respect to which the Option is being exercised, and such other representations and agreements as may be required by the
Company. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice
accompanied by the aggregate Exercise Price. 
 No Shares shall be issued pursuant to the exercise of an Option unless such issuance and
such exercise comply with Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to the Optionee on the date on which the Option is exercised with respect to such Shares. 

3. Optionee’s Representations. In the event the Shares have not been registered under the Securities Act of 1933, as amended,
at the time this Option is exercised, the Optionee shall, if required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached
hereto as Exhibit B. 

 4. Lock-Up Period. Optionee hereby agrees that Optionee shall not offer, pledge,
sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Stock (or other
securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other securities) of the Company held by Optionee
(other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred eighty (180) days following the effective date of any
registration statement of the Company filed under the Securities Act (or such other period as may be requested by the Company or the underwriters to accommodate regulatory restrictions on (i) the publication or other distribution of research
reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto). 

Optionee agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter which are
consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, Optionee shall
provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a registration statement
filed under the Securities Act. The obligations described in this Section shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a
registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other
securities) subject to the foregoing restriction until the end of said one hundred eighty (180) day (or other) period. Optionee agrees that any transferee of the Option or shares acquired pursuant to the Option shall be bound by this Section.

 5. Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at
the election of the Optionee: 
 (a) cash; 

(b) check; 
 (c) consideration
received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or 
 (d) surrender of
other Shares which, (i) in the case of Shares acquired from the Company, either directly or indirectly, have been owned by the Optionee, and not subject to a substantial risk of forfeiture, for more than six (6) months on the date of surrender,
and (ii) have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Exercised Shares. 

 6. Restrictions on Exercise. This Option may not be exercised until such time as the
Plan has been approved by the shareholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any Applicable Law. 

7. Non-Transferability of Option. This Option may not be transferred in any manner otherwise than by will or by the laws of descent
or distribution and may be exercised during the lifetime of Optionee only by Optionee. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee. 

8. Term of Option. This Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during
such term only in accordance with the Plan and the terms of this Option. 
 9. Tax Obligations. 

(a) Withholding Taxes. Optionee agrees to make appropriate arrangements with the Company (or the Parent or Subsidiary employing or
retaining Optionee) for the satisfaction of all Federal, state, local and foreign income and employment tax withholding requirements applicable to the Option exercise. Optionee acknowledges and agrees that the Company may refuse to honor the
exercise and refuse to deliver the Shares if such withholding amounts are not delivered at the time of exercise. 
 (b) Notice of
Disqualifying Disposition of ISO Shares. If the Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (1) the date two years
after the Date of Grant, and (2) the date one year after the date of exercise, the Optionee shall immediately notify the Company in writing of such disposition. Optionee agrees that Optionee may be subject to income tax withholding by the
Company on the compensation income recognized by the Optionee. 
 10. Entire Agreement; Governing Law. The Plan is incorporated
herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Optionee
with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company and Optionee. This Agreement is governed by the internal substantive laws but not
the choice of law rules of California. 
 11. Electronic Acceptance of Agreement and Electronic Delivery. Electronic Acceptance of
Agreement and Electronic Delivery. By the Optionee’s electronic acceptance of this Option, the Optionee and the Company agree that this Option is granted under and governed by the terms and conditions of the Plan, the Notice of Grant and the
Option Agreement. By accepting this Option, the Optionee consents to electronic delivery of all notifications and documents associated with the Option and agrees to participate in the Plan through any on-line or electronic system established and
maintained by the Company or a third party designated by the Company. 

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

The Exercise Price per Share represents an amount the Company believes to be no less than the fair market value of a share of Stock as of the
Date of Grant, determined in good faith in compliance with the requirements of Section 409A of the Code. However, there is no guarantee that the Internal Revenue Service will agree with the Company’s determination. A subsequent IRS
determination that the Exercise Price is less than such fair market value could result in adverse tax consequences to the Optionee. By signing below, the Optionee agrees that the Company, its directors, officers and shareholders shall not be
held liable for any tax, penalty, interest or cost incurred by the Optionee as a result of such determination by the IRS. The Optionee is urged to consult with his or her own tax advisor regarding the tax consequences of the Option, including
the application of Section 409A. 
 Optionee acknowledges receipt of a copy of the Plan and represents that he or she is familiar with the
terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Optionee has reviewed the Plan and this Option in their entirety, has had an opportunity to obtain the advice of counsel prior to
executing this Option and fully understands all provisions of the Option. Optionee hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan or this
Option. Optionee further agrees to notify the Company upon any change in the residence address indicated below.

San Francisco, CA 94108 
 Attention: Chief Financial Officer

 1. Exercise of Option. Effective as of today,
                    ,             , the undersigned (“Optionee”) hereby
elects to exercise Optionee’s option to purchase                     shares of the Common Stock (the “Shares”) of MuleSoft,
Inc. (the “Company”) under and pursuant to the 2006 Stock Plan (the “Plan”) and the Stock Option Agreement dated <award_date> (the “Option Agreement”). 

2. Delivery of Payment. Optionee herewith delivers to the Company the full purchase price of the Shares, as set forth in the Option
Agreement, and any and all withholding taxes due in connection with the exercise of the Option. 
 3. Representations of
Optionee. Optionee acknowledges that Optionee has received, read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms and conditions. 

4. Rights as Shareholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of
a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Shares shall be issued
to the Optionee as soon as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for which the record date is prior to the date of issuance except as
provided in Section 13 of the Plan. 
 5. Company’s Right of First Refusal. Before any Shares held by Optionee or any
transferee (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase
the Shares on the terms and conditions set forth in this Section (the “Right of First Refusal”). 
 (a) Notice of Proposed
Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each
proposed purchaser or other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration for which the Holder proposes to
transfer the Shares (the “Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). 

 (b) Exercise of Right of First Refusal. At any time within thirty (30) days after
receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the
purchase price determined in accordance with subsection (c) below. 
 (c) Purchase Price. The purchase price (“Purchase
Price”) for the Shares purchased by the Company or its assignee(s) under this Section shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith. 
 (d) Payment. Payment of the Purchase Price shall be made,
at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the assignee), or by any
combination thereof within 30 days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (e)
Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section, then the Holder may sell
or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within 120 days after the date of the Notice, that any such sale or other transfer is
effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares
described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by
the Holder may be sold or otherwise transferred. 
 (f) Exception for Certain Family Transfers. Anything to the contrary
contained in this Section notwithstanding, the transfer of any or all of the Shares during the Optionee’s lifetime or on the Optionee’s death by will or intestacy to the Optionee’s immediate family or a trust for the benefit of the
Optionee’s immediate family shall be exempt from the provisions of this Section. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the
transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall be no further transfer of such Shares except in accordance with the terms of this Section. 

(g) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon the earlier of (i)
first sale of Common Stock of the Company to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 

6. Tax Consultation. Optionee understands that Optionee may suffer adverse tax consequences as a result of Optionee’s purchase
or disposition of the Shares. Optionee represents that Optionee has consulted with any tax consultants Optionee deems advisable in connection with the purchase or disposition of the Shares and that Optionee is not relying on the Company for any
tax advice. 

 7. Restrictive Legends and Stop-Transfer Orders. 

(a) Legends. Optionee understands and agrees that the Company shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD
OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST REFUSAL HELD BY
THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT OF FIRST
REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER FOR
A PERIOD NOT TO EXCEED 180 DAYS FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF BY THE HOLDER WITHOUT THE CONSENT OF THE COMPANY 

(b) Stop-Transfer Notices. Optionee agrees that, in order to ensure compliance with the restrictions referred to herein, the
Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 

(c) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or
otherwise transferred in violation of any of the provisions of this Exercise Notice or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have
been so transferred. 
 8. Successors and Assigns. The Company may assign any of its rights under this Exercise Notice to single
or multiple assignees, and this Exercise Notice shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Exercise Notice shall be binding upon Optionee and his or
her heirs, executors, administrators, successors and assigns. 

 9. Interpretation. Any dispute regarding the interpretation of this Exercise Notice
shall be submitted by Optionee or by the Company forthwith to the Administrator, which shall review such dispute at its next regular meeting. The resolution of such a dispute by the Administrator shall be final and binding on all parties. 

10. Governing Law; Severability. This Exercise Notice is governed by the internal substantive laws, but not the choice of law
rules, of California. 
 11. Entire Agreement. The Plan and Option Agreement are incorporated herein by reference. This
Exercise Notice, the Plan, the Restricted Stock Purchase Agreement, the Option Agreement and the Investment Representation Statement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and may not be modified adversely to the Optionee’s interest except by means of a writing signed by the Company and Optionee.

INVESTMENT REPRESENTATION STATEMENT 
  

			
	OPTIONEE:	  	<first_name> <last_name>
		
	COMPANY:	  	MULESOFT, INC.
		
	SECURITY:	  	COMMON STOCK
		
	 GRANT ID:
	  	 <award_id>

		
	AMOUNT:	  	
		
	DATE:	  	

 In connection with the purchase of the above-listed Securities, the undersigned Optionee represents to the Company the
following: 
 (a) Optionee is aware of the Company’s business affairs and financial condition and has acquired sufficient information
about the Company to reach an informed and knowledgeable decision to acquire the Securities. Optionee is acquiring these Securities for investment for Optionee’s own account only and not with a view to, or for resale in connection with,
any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 
 (b)
Optionee acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of Optionee’s investment intent as expressed herein. In this connection, Optionee understands that, in the view of the Securities and Exchange Commission, the statutory basis for such
exemption may be unavailable if Optionee’s representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase
or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the future. Optionee further understands that the Securities must be held indefinitely unless they are subsequently registered under the
Securities Act or an exemption from such registration is available. Optionee further acknowledges and understands that the Company is under no obligation to register the Securities. Optionee understands that the certificate evidencing the
Securities will be imprinted with any legend required under applicable state securities laws. 
 (c) Optionee is familiar with the provisions
of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering
subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at 

 
the time of the grant of the Option to the Optionee, the exercise will be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting
requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities exempt under Rule 701 may be resold, subject to
the satisfaction of certain of the conditions specified by Rule 144, including: (1) the resale being made through a broker in an unsolicited “broker’s transaction” or in transactions directly with a market maker
(as said term is defined under the Securities Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of certain public information about the Company, (3) the amount of Securities being sold during any three month period
not exceeding the limitations specified in Rule 144(e), and (4) the timely filing of a Form 144, if applicable. 
 In the event that
the Company does not qualify under Rule 701 at the time of grant of the Option, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which requires the resale to occur not less than
one year after the later of the date the Securities were sold by the Company or the date the Securities were sold by an affiliate of the Company, within the meaning of Rule 144; and, in the case of acquisition of the Securities by an affiliate,
or by a non-affiliate who subsequently holds the Securities less than two years, the satisfaction of the conditions set forth in sections (1), (2), (3) and (4) of the paragraph immediately above. 

(d) Optionee further understands that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration
under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has
expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 will have a substantial burden of proof in establishing that an exemption from
registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Optionee understands that no assurances can be given that any such other
registration exemption will be available in such event.

 2006
STOCK PLAN 
 RESTRICTED STOCK PURCHASE AGREEMENT 

THIS AGREEMENT is made between <first_name> <last_name> (the “Purchaser”) and MuleSoft, Inc. (the “Company”)
or its assignees of rights hereunder as of                         ,         . 

Unless otherwise defined herein, the terms defined in the 2006 Stock Plan shall have the same defined meanings in this Agreement. 

RECITALS 
 A. Pursuant to
the exercise of the option (grant number <award_id>) granted to Purchaser under the Plan and pursuant to the Option Agreement dated <award_date> by and between the Company and Purchaser with respect to such grant (the
“Option”), which Plan and Option Agreement are hereby incorporated by reference, Purchaser has elected to purchase _________ of those shares of Common Stock which have not become vested under the vesting schedule set forth in the Option
Agreement (“Unvested Shares”). The Unvested Shares and the shares subject to the Option Agreement, which have become vested are sometimes collectively referred to herein as the “Shares.” 

B. As required by the Option Agreement, as a condition to Purchaser’s election to exercise the option, Purchaser must execute this
Agreement, which sets forth the rights and obligations of the parties with respect to Shares acquired upon exercise of the Option. 
 1.
Repurchase Option. 
 (a) If Purchaser’s status as a Service Provider is terminated for any reason, including for death and
Disability, the Company shall have the right and option for ninety (90) days from such date to purchase from Purchaser, or Purchaser’s personal representative, as the case may be, all of the Purchaser’s Unvested Shares as of the date of
such termination at the price paid by the Purchaser for such Shares (the “Repurchase Option”). 
 (b) Upon the occurrence of such
termination, the Company may exercise its Repurchase Option by delivering personally or by registered mail, to Purchaser (or his transferee or legal representative, as the case may be) with a copy to the escrow agent described in Section 2 below, a
notice in writing indicating the Company’s intention to exercise the Repurchase Option AND, at the Company’s option, (i) by delivering to the Purchaser (or the Purchaser’s transferee or legal representative) a check in the amount of
the aggregate repurchase price, or (ii) by the Company canceling an amount of the Purchaser’s indebtedness to the Company equal to the aggregate repurchase price, or (iii) by a combination of (i) and (ii) so that the combined payment and
cancellation of indebtedness equals such aggregate repurchase price. Upon delivery of such notice 

 
and payment of the aggregate repurchase price in any of the ways described above, the Company shall become the legal and beneficial owner of the Unvested Shares being repurchased and the rights
and interests therein or relating thereto, and the Company shall have the right to retain and transfer to its own name the number of Unvested Shares being repurchased by the Company. 

(c) Whenever the Company shall have the right to repurchase Unvested Shares hereunder, the Company may designate and assign one or more
employees, officers, directors or shareholders of the Company or other persons or organizations to exercise all or a part of the Company’s Repurchase Option under this Agreement and purchase all or a part of such Unvested Shares.

(d) If the Company does not elect to exercise the Repurchase Option conferred above by giving the requisite notice within ninety (90) days
following the termination, the Repurchase Option shall terminate. 
 (e) The Repurchase Option shall terminate in accordance with the vesting
schedule contained in Purchaser’s Option Agreement. 
 2. Transferability of the Shares; Escrow. 

(a) Purchaser hereby authorizes and directs the Secretary of the Company, or such other person designated by the Company, to transfer the
Unvested Shares as to which the Repurchase Option has been exercised from Purchaser to the Company. 
 (b) To insure the availability for
delivery of Purchaser’s Unvested Shares upon repurchase by the Company pursuant to the Repurchase Option under Section 1, Purchaser hereby appoints the Secretary, or any other person designated by the Company as escrow agent (the
“Escrow Agent”), as its attorney-in-fact to sell, assign and transfer unto the Company, such Unvested Shares, if any, repurchased by the Company pursuant to the Repurchase Option and shall, upon execution of this Agreement, deliver and
deposit with the Escrow Agent, the share certificates representing the Unvested Shares, together with the stock assignment duly endorsed in blank, attached hereto as Exhibit C-2. The Unvested Shares and stock assignment shall be held by
the Escrow Agent in escrow, pursuant to the Joint Escrow Instructions of the Company and Purchaser attached as Exhibit C-3 hereto, until the Company exercises its Repurchase Option, until such Unvested Shares are vested, or until such time as
this Agreement no longer is in effect. Upon vesting of the Unvested Shares, the Escrow Agent shall promptly deliver to the Purchaser the certificate or certificates representing such Shares in the Escrow Agent’s possession belonging to the
Purchaser, and the Escrow Agent shall be discharged of all further obligations hereunder; provided, however, that the Escrow Agent shall nevertheless retain such certificate or certificates as Escrow Agent if so required pursuant to other
restrictions imposed pursuant to this Agreement. 
 (c) The Company nor the Escrow Agent shall be liable for any act it may do or omit to do
with respect to holding the Shares in escrow and while acting in good faith and in the exercise of its judgment. 
 (d) Transfer or sale of
the Shares is subject to restrictions on transfer imposed by any applicable state and federal securities laws. Any transferee shall hold such Shares subject to all the provisions hereof and the Exercise Notice executed by the Purchaser with
respect to any Unvested Shares purchased by Purchaser and shall acknowledge the same by signing a copy of this Agreement. 

 3. Ownership, Voting Rights, Duties. This Agreement shall not affect in any way the
ownership, voting rights or other rights or duties of Purchaser, except as specifically provided herein. 
 4. Legends. The share
certificate evidencing the Shares issued hereunder shall be endorsed with the following legend (in addition to any legend required under applicable federal and state securities laws): 

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN
AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY. 
 5. Adjustment for
Stock Split. All references to the number of Shares and the purchase price of the Shares in this Agreement shall be appropriately adjusted to reflect any stock split, stock dividend or other change in the Shares, which may be made by the
Company pursuant to Section 13 of the Plan after the date of this Agreement. 
 6. Notices. Notices required hereunder shall
be given in person or by registered mail to the address of Purchaser shown on the records of the Company, and to the Company at their respective principal executive offices. 

7. Survival of Terms. This Agreement shall apply to and bind Purchaser and the Company and their respective permitted assignees and
transferees, heirs, legatees, executors, administrators and legal successors. 
 8. Section 83(b) Election. Purchaser hereby
acknowledges that he or she has been informed that, with respect to the exercise of an Option for Unvested Shares, an election (the “Election”) may be filed by the Purchaser with the Internal Revenue Service, within thirty (30) days of the
purchase of the exercised Shares, electing pursuant to Section 83(b) of the Code to be taxed currently on any difference between the purchase price of the exercised Shares and their Fair Market Value on the date of purchase. In the case of a
Nonstatutory Stock Option, this will result in a recognition of taxable income to the Purchaser on the date of exercise, measured by the excess, if any, of the Fair Market Value of the exercised Shares, at the time the Option is exercised over the
purchase price for the exercised Shares. Absent such an Election, taxable income will be measured and recognized by Purchaser at the time or times on which the Company’s Repurchase Option lapses. In the case of an Incentive Stock
Option, such an Election will result in a recognition of income to the Purchaser for alternative minimum tax purposes on the date of exercise, measured by the excess, if any, of the Fair Market Value of the exercised Shares, at the time the option
is exercised, over the purchase price for the exercised Shares. Absent such an Election, alternative minimum taxable income will be measured and recognized by Purchaser at the time or times on which the Company’s Repurchase Option lapses.
Purchaser is strongly encouraged to seek the advice of his or her own tax consultants in connection with the purchase of the Shares and the advisability of filing of the Election under Section 83(b) of the Code. A form of Election under Section
83(b) is attached hereto as Exhibit C-4 for reference. 

 PURCHASER ACKNOWLEDGES THAT IT IS PURCHASER’S SOLE RESPONSIBILITY AND NOT THE COMPANY’S
TO FILE TIMELY THE ELECTION UNDER SECTION 83(b) OF THE CODE, EVEN IF PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON PURCHASER’S BEHALF. 

9. Representations. Purchaser has reviewed with his own tax advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement. Purchaser is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. Purchaser understands that he (and not the
Company) shall be responsible for his own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement. 

10. Governing Law. This Agreement shall be governed by the internal substantive laws, but not the choice of law rules, of
California. 
 Purchaser represents that he has read this Agreement and is familiar with its terms and provisions. Purchaser hereby
agrees to accept as binding, conclusive and final all decisions or interpretations of the Board upon any questions arising under this Agreement. 

IN WITNESS WHEREOF, this Agreement is deemed made as of the date first set forth above.

“Purchaser”), you are hereby authorized and directed to hold the documents delivered to you pursuant to the terms of that certain Restricted Stock Purchase Agreement (the “Agreement”) between the Company and the undersigned, in

purchase price, and the time for a closing hereunder at the principal office of the Company. Purchaser and the Company hereby irrevocably authorize and direct you to close the transaction contemplated by such notice in accordance with the terms
of said notice. 
 2. At the closing, you are directed (a) to date the stock assignments necessary for the transfer in question,

3. Purchaser irrevocably authorizes the Company to deposit with you any certificates evidencing shares of stock to be held by you hereunder and
any additions and substitutions to said shares as defined in the Agreement. Purchaser does hereby irrevocably constitute and appoint you as Purchaser’s attorney-in-fact and agent for the term of this escrow to execute with respect to such
securities all documents necessary or appropriate to make such securities negotiable and to complete any transaction herein contemplated, including but not limited to the filing with any applicable state blue sky authority of any required

Company’s repurchase option has been exercised, you will deliver to Purchaser a certificate or certificates representing so many shares of stock as are not then subject to the Company’s repurchase option. Within 120 days after
cessation of Purchaser’s continuous employment by or services to the Company, or any parent or subsidiary of the Company, you will deliver to Purchaser a certificate or certificates representing the aggregate number of shares held or issued
pursuant to the Agreement and not purchased by the Company or its assignees pursuant to exercise of the Company’s repurchase option.

hereunder may be altered, amended, modified or revoked only by a writing signed by all of the parties hereto. 
 7. You shall be obligated

advice of your own attorneys shall be conclusive evidence of such good faith. 
 8. You are hereby expressly authorized to disregard any and
all warnings given by any of the parties hereto or by any other person or corporation, excepting only orders or process of courts of law and are hereby expressly authorized to comply with and obey orders, judgments or decrees of any court. In
case you obey or comply with any such order, judgment or decree, you shall not be liable to any of the parties hereto or to any other person, firm or corporation by reason of such compliance, notwithstanding any such order, judgment or decree being
subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction.

liable in any respect on account of the identity, authorities or rights of the parties executing or delivering or purporting to execute or deliver the Agreement or any documents or papers deposited or called for hereunder. 

10. You shall not be liable for the outlawing of any rights under the Statute of Limitations with respect to these Joint Escrow Instructions or
any documents deposited with you. 
 11. You shall be entitled to employ such legal counsel and other experts as you may deem necessary
properly to advise you in connection with your obligations hereunder, may rely upon the advice of such counsel, and may pay such counsel reasonable compensation therefor.

anyone all or any part of said securities until such disputes shall have been settled either by mutual written agreement of the parties concerned or by a final order, decree or judgment of a court of competent jurisdiction after the time for appeal
has expired and no appeal has been perfected, but you shall be under no duty whatsoever to institute or defend any such proceedings. 
 15.
Any notice required or permitted hereunder shall be given in writing and shall be deemed effectively given upon personal delivery or upon deposit in the United States Post Office, by registered or certified mail with postage and fees prepaid,

2006 STOCK PLAN 

RESTRICTED STOCK PURCHASE AGREEMENT 

Unless otherwise defined herein, the terms defined in the 2006 Stock Plan (the “Plan”) shall have the same defined meanings
in this Restricted Stock Purchase Agreement (the “Agreement”). 
  

	I.	NOTICE OF GRANT OF STOCK 

 Name:

Address:
 The undersigned
individual (the “Participant”) has been granted a Stock Purchase Rights to receive Common Stock (the “Stock Award”), subject to the terms and conditions of the Plan and this Agreement, as follows: 

 

			
		
	 Date of Grant:
	  	
		
	 Total Number of Shares of:
	  	
		
	 Common Stock:
	  	
		
	 Vesting Schedule:
	  	100% of the Shares will be fully vested as of the Date of Grant.

  

	II.	AGREEMENT 

 1. Grant of Stock. The Company hereby grants to the person
named in the Notice of Grant of Stock in Part I of this Agreement (“Participant”) under the Plan for services performed and to be performed by Participant for the Company and as a separate incentive in connection with his or her
services and not in lieu of any salary or other compensation for his or her services, the number of Shares set forth in the Notice of Grant of Stock, subject to all of the terms and conditions in this Agreement and the Plan, which is incorporated
herein by reference. Subject to Section 15(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Agreement, the terms and conditions of the Plan shall prevail. 

2. Participant’s Representations. In the event the Shares have not been registered under the Securities Act of 1933, as
amended, at the time this Restricted Stock Award is granted, Participant shall, if required by the Company, concurrently with the grant of this Restricted Stock Award, deliver to the Company his or her Investment Representation Statement in the form
attached hereto as Exhibit A, as well as any other representations necessary or appropriate, in the judgment of the Administrator, to comply with Applicable Law. 

 3. Lock-Up Period. Participant hereby agrees that Participant shall not offer,
pledge, sell, contract to sell, sell any Restricted Stock Award or contract to purchase, purchase any Restricted Stock Award or contract to sell, grant any Restricted Stock Award, right or warrant to purchase, lend, or otherwise transfer or dispose
of, directly or indirectly, any Common Stock (or other securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock
(or other securities) of the Company held by Participant (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred
and eighty (180) days following the effective date of any registration statement of the Company filed under the Securities Act (or such other period as may be requested by the Company or the underwriters to accommodate regulatory restrictions on
(i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor
provisions or amendments thereto). 
 Participant agrees to execute and deliver such other agreements as may be reasonably requested by the
Company or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities)
of the Company, Participant shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities
pursuant to a registration statement filed under the Securities Act. The obligations described in this Section 3 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms
that may be promulgated in the future, or a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to
the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred and eighty (180) day (or other) period. Participant agrees that any transferee of the Restricted Stock Award or Shares
acquired pursuant to the Restricted Stock Award shall be bound by this Section 3. 
 4. Transferability of Stock. The terms
of the Plan and this Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of Participant. 
 5.
Tax Obligations. 
 (a) Tax Withholding. Regardless of any action the Company or Participant’s employer (the
“Employer”) takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related withholding (“Tax-Related Items”), Participant acknowledges that the ultimate liability
for all Tax-Related Items legally due by him or her is and remains Participant’s responsibility and that Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection
with any aspect of the Stock Award, including the grant of the Stock Award, the subsequent sale of Shares acquired pursuant to the Stock Award, or the receipt of any dividends; and (2) do not commit to structure the terms of the grant or any
aspect of the Stock Award to reduce or eliminate Participant’s liability for Tax-Related Items. 

 (b) Participant will pay or make adequate arrangements satisfactory to Company and/or the
Employer to satisfy all withholding and payment on account obligations of Company and/or the Employer. In this regard, Participant authorizes Company and/or the Employer to withhold all applicable Tax-Related Items legally payable by
Participant from his or her• wages or other cash compensation paid to Participant by Company and/or the Employer or from proceeds of the sale of Shares. Alternatively, or in addition, if permissible under local law, Company may, in its
discretion, (1) sell or arrange for the sale of Shares that Participant acquires to meet the withholding obligation for Tax-Related Items, and/or (2) withhold in Shares, provided that Company only withholds the amount of Shares necessary
to satisfy the minimum withholding amount. Finally, Participant will pay to Company or the Employer any amount of Tax-Related Items that Company or the Employer may be required to withhold as a result of Participant’s participation in the
Plan or Participant’s receipt of Shares that cannot be satisfied by the means previously described. Company may refuse to deliver the Shares if Participant fails to comply with his or her obligations in connection with the Tax-Related
Items as described in this Section. 
 (c) Participant has reviewed with Participant’s own tax advisors the federal, state, local and
foreign tax consequences of this investment and the transactions contemplated by this Agreement. Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. Participant
understands that Participant (and not the Company) shall be responsible for Participant’s own tax liability that may arise as a result of the transactions contemplated by this Agreement. 

6. Acknowledgements. 
 (a)
Participant acknowledges receipt of a copy of the Plan (including any applicable appendixes or sub-plans thereunder) and represents that he or she is familiar with the terms and provisions thereof, and hereby accepts this Stock Award subject to all
of the terms and provisions thereof. Participant has reviewed the Plan (including any applicable appendixes or sub-plans thereunder) and this Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing
this Agreement and fully understands all provisions of the Agreement. Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan or this
Agreement. Participant further agrees to notify the Company upon any change in the residence address indicated below. 
 (b) The Company
(which may or may not be Participant’s employer) is granting the Stock Award. The Company will administer the Plan from outside Participant’s country of residence, and United States law will govern all Restricted Stock Awards granted
under the Plan. 
 (c) Participant acknowledges that benefits and rights provided under the Plan are wholly discretionary and, although
provided by the Company, do not constitute regular or periodic payments. Unless otherwise required by Applicable Law, the benefits and rights provided under the Plan are not to be considered part of Participant’s salary or compensation for
purposes of calculating any severance, resignation, redundancy or other end of service payments, vacation, bonuses, long-term service awards, indemnification, pension or retirement benefits, or any other payments, benefits or rights of any
kind. Participant waives any and all rights to compensation or damages as a result of the termination of employment with the Employer for any reason whatsoever insofar as those rights result or may result from: 

 (i) the loss or diminution in value of such rights under the Plan, or 

(ii) Participant ceasing to have any rights under, or ceasing to be entitled to any rights under the Plan as a result of such termination.

 (d) The grant of the Restricted Stock Award, and any future grant of Stock Awards under the Plan is entirely voluntary, and at the
complete discretion of the Company. Neither the grant of the Stock Award nor any future grant of a Stock Award by the Company will be deemed to create any obligation to grant any further Stock Awards, whether or not such a reservation is
explicitly stated at the time of such a grant. The Company has the right, at any time to amend, suspend or terminate the Plan. 
 (e)
The Plan will not be deemed to constitute, and will not be construed by Participant to constitute, part of the terms and conditions of employment, and neither the Company or the Employer will incur any liability of any kind to Participant as a
result of any change or amendment, or any cancellation, of the Plan at any time. 
 (f) Participation in the Plan will not be deemed to
constitute, and will not be deemed by Participant to constitute, an employment or labor relationship of any kind with the Company. 
 (g) In
the event of termination of Participant’s employment (whether or not in breach of local labor laws), Participant’s right to vest in the Stock Award under the Plan, if any, will terminate effective as of the date that Participant is no
longer actively employed and will not be extended by any notice period mandated under local law (e.g., active employment would not include a period of “garden leave” or similar period pursuant to local law); the Administrator shall
have the exclusive discretion to determine when Participant is no longer actively employed for purposes of his or her Restricted Stock Award grant. 

7. Data Privacy. By entering into this Agreement, and as a condition of the grant of the Restricted Stock Award, Participant hereby
explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of his or her personal data as described in this document by and among, as applicable, the Employer, and Company and its Subsidiaries and
affiliates for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. 

Participant understands that the Company and the Employer, its Parent or any Subsidiary may hold certain personal information about
Participant, including, but not limited to, Participant’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any Shares or directorships held in the
Company, details of all Stock Awards or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor, for the purpose of implementing, administering and managing the Plan
(“Data”). Participant understands that Data may be transferred to any third 

 
parties assisting in the implementation, administration and management of the Plan, that these recipients may be located in Participant’s country or elsewhere, and that the recipients’
country (e.g., the United States) may have different data privacy laws and protections than Participant’s country. Participant understands that he or she may request a list with the names and addresses of any potential recipients of
the Data by contacting Participant’s local human resources representative. Participant authorizes the recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purpose of implementing,
administering and managing Participant’s participation in the Plan, including any requisite transfer of such Data as may be required to a broker or other third party with whom Participant may elect to deposit any shares of stock acquired
pursuant to the Restricted Stock Award. Participant understands that Data will be held only as long as is necessary to implement, administer and manage Participant’s participation in the Plan. Participant understands that he or she
may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing
Participant’s local human resources representative. Participant understands, however, that refusing or withdrawing his or her consent may affect Participant’s ability to participate in the Plan. For more information on the
consequences of Participant’s refusal to consent or withdrawal of consent, Participant understands that he or she may contact his or her local human resources representative. 

8. English Language. Participant has received the terms and conditions of this Agreement and any other related communications, and
Participant consents to having received these documents in English. If Participant has received this Agreement or any other document related to the Plan translated into a language other than English and if the translated version is different
than the English version, the English version will control. 
 9. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND
AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY
WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 

10. Company’s Right of First Refusal. Before any Shares held by Participant or any transferee (either being sometimes referred
to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions
set forth in this Section 10 (the “Right of First Refusal”). 
 (a) Notice of Proposed Transfer. The Holder
of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other
transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Shares
(the “Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). 

 (b) Exercise of Right of First Refusal. At any time within thirty (30) days after
receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the
purchase price determined in accordance with subsection (e) below. 
 (c) Purchase Price. The purchase price (“Right of
First Refusal Price”) for the Shares purchased by the Company or its assignee(s) under this Section 10 shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board in good faith. 
 (d) Payment. Payment of the Right of First Refusal
Price shall be made, at the Restricted Stock Award of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee,
to the assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice. 

(e) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee
are not purchased by the Company and/or its assignee(s) as provided in this Section 10, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or
other transfer is consummated within one hundred and twenty (120) days after the date of the Notice, that any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in
writing that the provisions of this Section 10 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new
Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 

(f) Exception for Certain Family Transfers. Anything to the contrary contained in this Section 10 notwithstanding, the
transfer of any or all of the Shares during Participant’s lifetime or on Participant’s death by will or intestacy to Participant’s immediate family or a trust for the benefit of Participant’s immediate family shall be exempt from
the provisions of this Section 10. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold
the Shares so transferred subject to the provisions of this Agreement, including but not limited to this Section 10, and there shall be no further transfer of such Shares except in accordance with the terms of this Section 10. 

(g) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon the earlier of
(i) the first sale of Common Stock of the Company to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 

 11. Restrictive Legends and Stop-Transfer Orders. 

(a) Legends. Participant understands and agrees that the Company shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD
OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER, A RIGHT OF FIRST REFUSAL IN FAVOR
OF THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE STOCK AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT OF
FIRST REFUSAL IN FAVOR OF THE ISSUER OR ITS ASSIGNEE(S) ARE BINDING ON TRANSFEREES OF THESE SHARES. 
 THE SHARES REPRESENTED BY THIS
CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER FOR A PERIOD OF TIME FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES SET FORTH IN AN AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE
SHARES AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF BY THE HOLDER PRIOR TO THE EXPIRATION OF SUCH PERIOD WITHOUT THE CONSENT OF THE COMPANY OR THE MANAGING UNDERWRITER. 

(b) Stop-Transfer Notices. Participant agrees that, in order to ensure compliance with the restrictions referred to herein, the
Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 

(c) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or
otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so
transferred. 
 12. Address for Notices. Any notice to be given to the Company under the terms of this Award Agreement will be
addressed to the Company at MuleSoft, Inc., 77 Geary Street, Suite 400, San Francisco, CA 94108, Attention: Chief Financial Officer, or at such other address as the Company may hereafter designate in writing. 

 13. Electronic Delivery. The Company may, in its sole discretion, decide to deliver
any documents related to the Shares awarded under the Plan or future Shares that may be awarded under the Plan by electronic means or request Participant’s consent to participate in the Plan by electronic means. Participant hereby consents
to receive such documents by electronic delivery and agrees to participate in the Plan through any on-line or electronic system established and maintained by the Company or another third party designated by the Company. 

14. No Waiver. Either party’s failure to enforce any provision or provisions of this Agreement shall not in any way be
construed as a waiver of any such provision or provisions, nor prevent that party from thereafter enforcing each and every other provision of this Agreement. The rights granted both parties herein are cumulative and shall not constitute a
waiver of either party’s right to assert all other legal remedies available to it under the circumstances. 
 15. Successors and
Assigns. The Company may assign any of its rights under this Agreement to single or multiple assignees, and this Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer
herein set forth, this Agreement shall be binding upon Participant and his or her heirs, executors, administrators, successors and assigns. The rights and obligations of Participant under this Agreement may only be assigned with the prior
written consent of the Company. 
 16. Interpretation. The Administrator will have the power to interpret the Plan and this
Agreement and to adopt such rules for the administration, interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules. All actions taken and all interpretations and determinations made by the
Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons. Neither the Administrator nor any person acting on behalf of the Administrator will be personally liable for any action,
determination or interpretation made in good faith with respect to the Plan or this Agreement. 
 17. Additional
Documents. Participant agrees upon request to execute any further documents or instruments necessary or desirable to carry out the purposes or intent of this Agreement. 

18. Governing Law; Severability. This Agreement is governed by the internal substantive laws, but not the choice of law rules, of
California. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Agreement shall continue in full force and effect. 

19. Entire Agreement. The Plan is incorporated herein by reference. The Plan and this Agreement (including the exhibits
referenced herein) constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter
hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant.

 In connection with the purchase of the above-listed Securities, the undersigned Participant represents to the
Company the following: 
 (a) Participant is aware of the Company’s business affairs and financial condition and has acquired sufficient
information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Participant is acquiring these Securities for investment for Participant’s own account only and not with a view to, or for resale in
connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 

(b) Participant acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have
not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Participant’s investment intent as expressed herein. In this
connection, Participant understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Participant’s representation was predicated solely upon a present intention to hold
these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the
future. Participant further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Participant further acknowledges
and understands that the Company is under no obligation to register the Securities. Participant understands that the certificate evidencing the Securities shall be imprinted with any legend required under applicable state securities laws. 

(c) Participant is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance,
permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer
qualifies under Rule 701 at the time of the grant of the Restricted Stock Award to Participant, the exercise shall be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of
Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days 

 
thereafter (or such longer period as any market stand-off agreement may require) the Securities exempt under Rule 701 may be resold, subject to the satisfaction of the applicable conditions
specified by Rule 144, including in the case of affiliates (1) the availability of certain public information about the Company, (2) the amount of Securities being sold during any three (3) month period not exceeding specified
limitations, (3) the resale being made in an unsolicited “broker’s transaction”, transactions directly with a “market maker” or “riskless principal transactions” (as those terms are defined under the
Securities Exchange Act of 1934) and (4) the timely filing of a Form 144, if applicable. 
 In the event that the Company does not
qualify under Rule 701 at the time of grant of the Restricted Stock Award, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which may require (i) the availability of current public
information about the Company; (ii) the resale to occur more than a specified period after the purchase and full payment (within the meaning of Rule 144) for the Securities; and (iii) in the case of the sale of Securities by an affiliate,
the satisfaction of the conditions set forth in sections (2), (3) and (4) of the paragraph immediately above. 
 (d) Participant further
understands that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption shall be required; and that,
notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and
otherwise than pursuant to Rules 144 or 701 shall have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in
such transactions do so at their own risk. Participant understands that no assurances can be given that any such other registration exemption shall be available in such event.

 (e) Discretion to Determine Criteria. Notwithstanding any contrary provision of the Plan,

(iii) business divestitures and acquisitions, (iv) cash flow, (v) cash position, (vi) change to recurring revenue, (vii) earnings (which may include any calculation of earnings, including but not limited to earnings before

criteria. As determined by the Committee, the performance goals may be based on generally accepted accounting principles (“GAAP”) or non-GAAP results and any actual results may be adjusted by the
Committee for one-time items or unbudgeted or unexpected items when determining whether the performance goals have been met. The goals may be on the basis of any factors the Committee determines relevant, and
may be on an individual, divisional, business unit or Company-wide basis. Any criteria used may be measured on such basis as the Committee determines, including but not limited to, as applicable, (A) in absolute terms, (B) in combination
with another performance goal or goals (for example, but not by way of limitation, as a ratio or matrix), (C) in relative terms (including, but not limited to, results for other periods, passage of time and/or against another company or
companies or an index or indices), (D) on a per-share basis, (E) against the performance of the Company as a whole or a segment of the Company and/or (F) on a
pre-tax or after-tax basis. The performance goals may differ from Participant to Participant and from award to award. Failure to meet the goals will result in a failure
to earn the Target Award, except as provided in Section 3(d). 
 4. Payment of Awards. 

(a) Right to Receive Payment. Each Actual Award will be paid solely from the general assets of the Company. Nothing in this Plan will
be construed to create a trust or to establish or evidence any Participant’s claim of any right other than as an unsecured general creditor with respect to any payment to which he or she may be entitled. 

(b) Timing of Payment. Payment of each Actual Award shall be made as soon as practicable after the end of the Performance Period during
which the Actual Award was earned and after the Actual Award is approved by the Committee, but in no event following the later of (i) the fifteenth (15th) day of the third (3rd) month of the Fiscal Year immediately following the Fiscal Year in
which the Participant’s Actual Award has been earned and no longer is subject to a substantial risk of forfeiture, and (ii) March 15 of the calendar year immediately following the calendar year in which the Participant’s Actual
Award has been earned and no longer is subject to a substantial risk of forfeiture. Unless otherwise determined by the Committee, to earn an Actual Award a Participant must be employed by the Company or any Affiliate on the date the Actual Award is
paid. 

  
 -3- 

 It is the intent that this Plan comply with the requirements of Code Section 409A so that
none of the payments to be provided hereunder will be subject to the additional tax imposed under Code Section 409A, and any ambiguities herein will be interpreted to so comply. 

(c) Form of Payment. Each Actual Award will be paid in cash (or its equivalent) in a single lump sum. 

(d) Payment in the Event of Death or Disability. If a Participant dies or becomes Disabled prior to the payment of an Actual Award
earned by him or her prior to death or Disability for a prior Performance Period, the Actual Award will be paid to his or her estate or to the Participant, as the case may be, subject to the Committee’s discretion to reduce or eliminate any
Actual Award otherwise payable. 
 5. Plan Administration. 

(a) Committee is the Administrator. The Plan will be administered by the Committee. The Committee will consist of not less than two
(2) members of the Board. The members of the Committee will be appointed from time to time by, and serve at the pleasure of, the Board. 

(b) Committee Authority. It will be the duty of the Committee to administer the Plan in accordance with the Plan’s provisions. The
Committee will have all powers and discretion necessary or appropriate to administer the Plan and to control its operation, including, but not limited to, the power to (i) determine which Employees will be granted awards, (ii) prescribe
the terms and conditions of awards, (iii) interpret the Plan and the awards, (iv) adopt such procedures and subplans as are necessary or appropriate to permit participation in the Plan by Employees who are foreign nationals or employed
outside of the United States, (v) adopt rules for the administration, interpretation and application of the Plan as are consistent therewith, and (vi) interpret, amend or revoke any such rules. 

(c) Decisions Binding. All determinations and decisions made by the Committee, the Board, and any delegate of the Committee pursuant to
the provisions of the Plan will be final, conclusive, and binding on all persons, and will be given the maximum deference permitted by law. 

(d) Delegation by Committee. The Committee, in its sole discretion and on such terms and conditions as it may provide, may delegate all
or part of its authority and powers under the Plan to one or more directors and/or officers of the Company. 
 (e) Indemnification.
Each person who is or will have been a member of the Committee will be indemnified and held harmless by the Company against and from (i) any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in
connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan or any award, and (ii) from any and
all amounts paid by him or her in settlement thereof, with the Company’s approval, or paid by him or her in satisfaction of any judgment in any such claim, action, suit, or proceeding against him or her, provided he or she will give the

  
 -4- 

 
Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification will
not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company’s Certificate of Incorporation or Bylaws, by contract, as a matter of law, or otherwise, or under any power that the Company may
have to indemnify them or hold them harmless. 
 6. General Provisions. 

(a) Tax Withholding. The Company will withhold all applicable taxes from any Actual Award, including any federal, state and local taxes
(including, but not limited to, the Participant’s FICA and SDI obligations). 
 (b) No Effect on Employment or Service. Nothing
in the Plan will interfere with or limit in any way the right of the Company to terminate any Participant’s employment or service at any time, with or without cause. For purposes of the Plan, transfer of employment of a Participant between the
Company and any one of its Affiliates (or between Affiliates) will not be deemed a Termination of Service. Employment with the Company and its Affiliates is on an at-will basis only. The Company expressly
reserves the right, which may be exercised at any time and without regard to when during a Performance Period such exercise occurs, to terminate any individual’s employment with or without cause, and to treat him or her without regard to the
effect that such treatment might have upon him or her as a Participant. 
 (c) Participation. No Employee will have the right to be
selected to receive an award under this Plan, or, having been so selected, to be selected to receive a future award. 
 (d)
Successors. All obligations of the Company under the Plan, with respect to awards granted hereunder, will be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase,
merger, consolidation, or otherwise, of all or substantially all of the business or assets of the Company. 
 (e) Beneficiary
Designations. If permitted by the Committee, a Participant under the Plan may name a beneficiary or beneficiaries to whom any vested but unpaid award will be paid in the event of the Participant’s death. Each such designation will revoke
all prior designations by the Participant and will be effective only if given in a form and manner acceptable to the Committee. In the absence of any such designation, any vested benefits remaining unpaid at the Participant’s death will be paid
to the Participant’s estate. 
 (f) Nontransferability of Awards. No award granted under the Plan may be sold, transferred,
pledged, assigned, or otherwise alienated or hypothecated, other than by will, by the laws of descent and distribution, or to the limited extent provided in Section 6(e). All rights with respect to an award granted to a Participant will be
available during his or her lifetime only to the Participant. 
 7. Amendment, Termination, and Duration. 

(a) Amendment, Suspension, or Termination. The Board, in its sole discretion, may amend or terminate the Plan, or any part thereof, at
any time and for any reason. 

  
 -5- 

 
The amendment, suspension or termination of the Plan will not, without the consent of the Participant, alter or impair any rights or obligations under any Actual Award theretofore earned by such
Participant. No award may be granted during any period of suspension or after termination of the Plan. 
 (b) Duration of Plan. The
Plan will commence on the date specified herein, and subject to Section 7(a) (regarding the Board’s right to amend or terminate the Plan), will remain in effect thereafter. 

8. Legal Construction. 

(a) Gender and Number. Except where otherwise indicated by the context, any masculine term used herein also will include the feminine;
the plural will include the singular and the singular will include the plural. 
 (b) Severability. In the event any provision of the
Plan will be held illegal or invalid for any reason, the illegality or invalidity will not affect the remaining parts of the Plan, and the Plan will be construed and enforced as if the illegal or invalid provision had not been included. 

(c) Requirements of Law. The granting of awards under the Plan will be subject to all applicable laws, rules and regulations, and to
such approvals by any governmental agencies or national securities exchanges as may be required. 
 (d) Governing Law. The Plan and
all awards will be construed in accordance with and governed by the laws of the State of California, but without regard to its conflict of law provisions.
