 Exhibit 10.2 

BILL.COM, INC. 
 2006
EQUITY INCENTIVE PLAN 
 As Adopted by the Board on April 21, 2006 and amended through October 22, 2015 

1. PURPOSE. The purpose of this Plan is to provide incentives to attract, retain and motivate eligible persons
whose present and potential contributions are important to the success of the Company its Parent and any Subsidiaries, by offering them an opportunity to participate in the Company’s future performance through awards of Options and Restricted
Stock. Capitalized terms not defined elsewhere in the text are defined in Section 22 hereof. Although this Plan is intended to be a written compensatory benefit plan within the meaning of Rule 701 promulgated under the Securities Act,
Awards may be granted which do not qualify for exemption under Rule 701 or Section 25102(o) of the California Corporations Code (“Section 25102(o)”). Any requirement of this Plan legally
required only because of Section 25102(o) need not apply if the Committee so determines pursuant to a duly adopted resolution recorded in its minutes. 

2. SHARES SUBJECT TO THE PLAN. 

2.1 Number of Shares Available. Subject to Sections 2.2 and 17 hereof, the total number of Shares reserved and
available for grant and issuance pursuant to this Plan will be 14,943,073 Shares or such lesser number of Shares as permitted by applicable law. 

Subject to Sections 2.2, 5.10 and 17 hereof, if Shares: (a) are subject to an Award that terminates without such Shares being issued, or (b) are
issued pursuant to an Award, but are forfeited or repurchased by the Company at the original issue price; then such Shares will again be available for grant and issuance under this Plan. At all times the Company will reserve and keep available the
number of Shares necessary to satisfy the requirements of all Awards then outstanding under this Plan. 
 To the extent required by applicable law, in no
event shall the total number of Shares issued (counting each reissuance of a Share that was previously issued and then forfeited or repurchased by the Company as a separate issuance) under the Plan upon exercise of ISOs (defined in Section 5
below) exceed 29,886,146 Shares (adjusted in proportion to any adjustments under Section 2.2 hereof) over the term of the Plan. 

2.2 Adjustment of Shares. In the event that the number of outstanding shares of the Company’s common stock is
changed by a stock dividend, recapitalization, stock split, reverse stock split, subdivision, combination, reclassification, spin-off or similar change in the capital structure of the Company without
consideration, then (a) the number of Shares reserved for issuance under this Plan, and (b) the Exercise Prices and Purchase Prices of, and number of Shares subject to, then outstanding Awards will be proportionately adjusted, subject to
any required action by the Board or the stockholders of the Company and compliance with applicable securities laws; provided, however, that fractions of a Share will not be issued but will either be paid in cash at the Fair Market Value of such
fraction of a Share or will be rounded down to the nearest whole Share, as determined by the Committee; and provided, further, that the Exercise Price per share of any Option may not be decreased to below the par value of a Share. 

 3. ELIGIBILITY. ISOs (as defined in Section 5 hereof) may
be granted only to employees (including officers and directors who are also employees) of the Company or of a Parent or Subsidiary. All other types of Award may be granted to any employee, officer, director or consultant of the Company or any Parent
or Subsidiary; provided with respect to any consultant, however, that such consultant is a natural person and the Award is in full or partial compensation for bona fide services unconnected with any offer and sale of securities in a capital-raising
transaction. Any Participant may be granted more than one Award under this Plan. 
 4. ADMINISTRATION. 

4.1 Authority. The Committee will administer this Plan. Subject to the general purposes, terms and conditions of this
Plan, and to the direction of the Board, the Committee will have full power to implement and carry out this Plan. Without limitation, the Committee will have the authority to: 

(a) construe and interpret this Plan, any Award Agreement and any other agreement or document executed pursuant to this Plan; 

(b) prescribe, amend and rescind rules and regulations relating to this Plan; 

(c) approve persons to receive Awards; 

(d) determine the form and terms of Awards; 

(e) determine the number of Shares or other consideration subject to Awards; 

(f) determine whether Awards will be granted singly, in combination with, in tandem with, in replacement of, or as alternatives to, other
Awards or awards under any other incentive or compensation plan of the Company or any Parent or Subsidiary; 
 (g) determine whether
Section 25102(o) is to apply to an Award; 
 (h) grant waivers of any conditions of this Plan or any Award; 

(i) determine the terms of vesting, exercisability and payment of Awards; 

(j) correct any defect, supply any omission, or reconcile any inconsistency in this Plan, any Award, any Award Agreement or any Exercise
Agreement; 
 (k) determine whether an Award has been earned; 

(l) delegate to one or more officers of the Company the authority to grant Awards within parameters established by the Committee, provided
each such officer is a member of the Board and subject to applicable law (for example, the corporate governance laws of the state of the Company’s incorporation); 

  
 2 

 (m) delegate authority to grant Awards to a committee comprised solely of two, or more,
“outside directors” (as defined in the regulations promulgated under Section 162(m) of the Code); make all other determinations necessary or advisable for the administration of this Plan; and 

(n) extend the vesting period beyond a Participant’s Termination Date. 

4.2 Committee Discretion. Any determination made by the Committee with respect to any Award will be made in its sole
discretion, provided such determination does not contravene any other express term of this Plan or direction of the Board, either: (a) at the time of grant of the Award, or (b) at any later time, subject to Section 5.9 hereof and
provided such determination does not contravene any express term of such Award. Any such determination will be final and binding on the Company and on all persons having an interest in any Award affected by such determination. Unless the Committee
determines in writing that Section 409A of the Code is to apply with respect to a particular Award granted to a Participant, the terms of each Award granted hereunder shall be such as shall not cause such Award to be subject to
Section 409A of the Code. Any term in any such Award that causes it to be subject to Section 409A may, at the election of the Committee acting in its sole discretion, be modified so as to cause the Award not to be subject to
Section 409A and if such modification is not possible then the Committee shall determine in its sole discretion whether such provision shall be void and without effect or the entire Award shall be rescinded and void. 

5. OPTIONS. The Committee will determine at, or prior to, the date of grant of each Option whether such Option
will be an “incentive stock option” within the meaning of Section 422 of the Code (“ISO”) or a nonqualified stock option (“NQSO”), the number of Shares subject to the Option, the
Exercise Price of the Option, the period during which the Option may be exercised, and all other terms and conditions of the Option, subject to the following: 

5.1 Form of Option Grant. Each Option granted under this Plan will be evidenced by an Award Agreement, expressly
identifying the Option as an ISO or an NQSO (“Stock Option Agreement”), which will: (a) be in such form and contain such provisions (which need not be the same for each Participant) as the Committee may from time to time
approve, and (b) comply with and be subject to the terms and conditions of this Plan. 
 5.2 Date of Grant. The
date of grant of an Option will be the date on which the Committee makes the determination to grant such Option, unless a later date of grant is specified by the Committee. The Stock Option Agreement and a copy of this Plan must be delivered to the
Participant within a reasonable time after the date of grant of the Option. 
 5.3 Exercise Period. Options may be
exercisable immediately but subject to repurchase pursuant to Section 11 hereof or may be exercisable within the times or upon the events determined by the Committee as set forth in the Stock Option Agreement governing such Option; but in no
event shall an Option granted to an employee who is a non-exempt employee for purposes of overtime pay under the Fair Labor Standards Act of 1938, be exercisable earlier than six (6) months after its date
of grant. The Committee also may provide for Options to become 

  
 3 

 
exercisable at one time or from time to time, periodically or otherwise, in such number of Shares or percentage of Shares as the Committee determines. Subject to earlier termination of the Option
as provided herein, to the extent Section 25102(o) is intended to apply, each Participant who is not an officer, director or consultant of the Company or of a Parent or Subsidiary shall have the right to exercise an Option granted hereunder at
the rate of no less than twenty percent (20%) per year over five (5) years from the date such Option is granted. 
 (a) Subject to the
terms of this Plan, any Option will expire no later than the latest date set forth in the Stock Option Agreement for the Option. 
 (b) Any
Option which is an ISO, or to which Section 25102(o) is to apply, will expire and cease to be exercisable on the date that is the tenth anniversary of the date the Option is granted. 

(c) Any ISO granted to a Ten Percent Stockholder will expire and cease to be exercisable on the date that is the fifth anniversary of the date
the ISO is granted. 
 (d) Any Option held by a Participant who is Terminated for Cause will expire and cease to be exercisable on such
Participant’s Termination Date unless determined otherwise by the Committee. 
 5.4 Exercise Price. The Exercise
Price of an Option will be determined by the Committee when the Option is granted, subject to the following: 
 (a) If the Option is one to
which Section 25102(o) is to apply, then the Exercise Price shall not be less than eighty-five percent (85%) of the Fair Market Value of the Shares on the date of grant and if granted to a Ten Percent Stockholder, then the Exercise Price shall
not be less than one hundred ten percent (110%) of the Fair Market Value of the Shares on the date of grant; 
 (b) Otherwise, if the Option
is an ISO granted to a Ten Percent Stockholder, then the Exercise Price shall not be less than one hundred ten percent (110%) of the Fair Market Value of the Shares on the date of grant. 

5.5 Method of Exercise. Options may be exercised only by delivery to the Company of a written stock option exercise
agreement (the “Exercise Agreement”) in a form approved by the Committee (which need not be the same for each Participant). The Exercise Agreement will state (a) the number of Shares being purchased, (b) the
restrictions imposed on the Shares purchased under such Exercise Agreement, if any, and (c) such representations and agreements regarding Participant’s investment intent and access to information and other matters, if any, as may be
required or desirable by the Company to comply with applicable securities laws. Participant shall execute and deliver to the Company the Exercise Agreement together with payment in full of the Exercise Price, and any applicable taxes, for the number
of Shares being purchased. 

  
 4 

 5.6 Termination. Subject to earlier termination pursuant to Sections 17
and 18 hereof and unless a different exercise period is expressly set forth in the Stock Option Agreement, the exercise period of an Option is always subject to the following: 

(a) If the Participant is Terminated for any reason other than death, Disability or for Cause, then the Participant may exercise such
Participant’s Options only to the extent that such Options are exercisable as to Vested Shares upon the Termination Date or as otherwise determined by the Committee. Such Options must be exercised by the Participant, if at all, within three
(3) months after the Termination Date (or within such longer or shorter time period (not less than thirty (30) days if granted to a non-officer employee to whom Section 25102(o) is applicable)
after the Termination Date as may be determined by the Committee, with any exercise occurring three (3) months after the Termination Date deemed to be exercise of an NQSO) but in any event, no later than the applicable expiration date
determined under Section 5.3 above. 
 (b) If the Participant is Terminated because of Participant’s death or Disability (or the
Participant dies within three (3) months after a Termination other than for Cause), then Participant’s Options may be exercised only to the extent that such Options are exercisable as to Vested Shares by Participant on the Termination Date
or as otherwise determined by the Committee. Such options must be exercised by Participant (or Participant’s legal representative or authorized assignee), if at all, within twelve (12) months after the Termination Date (or within such
shorter time period, not less than six (6) months if granted to a non-officer employee to whom Section 25102(o) is applicable). The post-termination exercise period for Termination due to death or
Disability may be for a longer time period than twelve (12) months, but shall not exceed five (5) years, after the Termination Date, if so determined by the Committee. In no event, however, shall the post-termination exercise period extend
beyond the applicable expiration date determined under Section 5.3 above. 
 (c) In the case of an ISO however, any exercise beyond
(a) three (3) months after the Termination Date when the Termination is for any reason other than the Participant’s death or “permanent and total disability”, within the meaning of Section 22(e)(3) of the Code, or
(b) twelve (12) months after the Termination Date when the Termination is for Participant’s “permanent and total disability” (within the meaning of Section 22(e)(3) of the Code, shall be deemed to be exercise of an
NQSO. 
 (d) When a Participant is Terminated for Cause, such Participant’s Options, may be exercised to no extent greater than such
Options are exercisable as to Vested Shares upon the Termination Date and such Options shall expire as determined under Section 5.3 above. 

5.7 Limitations on Exercise. The Committee may specify a reasonable minimum number of Shares that may be purchased on any
exercise of an Option, provided that such minimum number will not prevent Participant from exercising the Option for the full number of Shares for which it is then exercisable. 

5.8 Limitations on ISOs. The aggregate Fair Market Value (determined as of the date of grant) of Shares with respect to
which ISOs are exercisable for the first time by a Participant during any calendar year (under this Plan or under any other incentive stock option plan of the Company or any Parent or Subsidiary) will not exceed One Hundred Thousand Dollars
($100,000). If the Fair Market Value of Shares on the date of grant with respect to which ISOs are exercisable for the first time by a Participant during any calendar year exceeds One Hundred Thousand Dollars ($100,000), then the Options for the
first One Hundred Thousand Dollars 

  
 5 

 
($100,000) worth of Shares to become exercisable in such calendar year will be ISOs and the Options for the amount in excess of One Hundred Thousand Dollars ($100,000) that become exercisable in
that calendar year will be NQSOs and such distinction shall be documented in separate Stock Option Agreements per Section 5.1 above. In the event that the Code or the regulations promulgated thereunder are amended after the Effective Date to
provide for a different limit on the Fair Market Value of Shares permitted to be subject to ISOs, then such different limit will be automatically incorporated herein and will apply to any Options granted after the effective date of such amendment.

 5.9 Modification, Extension or Renewal. The Committee may modify, extend or renew outstanding Options and authorize
the grant of new Options in substitution therefor, provided that any such action may not, without the written consent of a Participant, impair any of such Participant’s rights under any Option previously granted. Any outstanding ISO that is
modified, extended, renewed or otherwise altered will be treated in accordance with Section 424(h) of the Code. Subject to Section 5.10 hereof, the Committee may reduce the Exercise Price of outstanding Options without the consent of
Participants by a written notice to them; provided, however, that the Exercise Price may not be reduced below the minimum Exercise Price that would be permitted under Section 5.4 hereof for Options granted on the date the action is taken to
reduce the Exercise Price; provided, further, that the Exercise Price per share will not be reduced below the par value, if any, of a Share. 

5.10 No Disqualification. Notwithstanding any other provision in this Plan, no term of this Plan relating to ISOs will be
interpreted, amended or altered, nor will any discretion or authority granted under this Plan be exercised, so as to disqualify this Plan under Section 422 of the Code or, without the consent of the Participant, to disqualify any
Participant’s ISO under Section 422 of the Code. 
 6. RESTRICTED STOCK AWARDS. A Restricted Stock
Award is an Award made in the form of a thirty-day offer by the Company to sell Shares that are subject to certain specified restrictions. The Committee will determine all the terms and conditions of the
Restricted Stock Award (such as, the number of Shares, the Purchase Price and the restrictions to which the Shares will be subject) subject to the following: 

6.1 Restricted Stock Purchase Agreement. All purchases under a Restricted Stock Award will be evidenced by an Award
Agreement (“Restricted Stock Purchase Agreement”) that will be in such form (which need not be the same for each Participant) as the Committee will from time to time approve, and will comply with and be subject to the terms
and conditions of this Plan. The Participant’s acceptance of the Restricted Stock Award is accomplished by the Participant’s execution and delivery of the Restricted Stock Purchase Agreement and full payment for the Shares to the Company
within thirty (30) days from the date the Restricted Stock Purchase Agreement is delivered to the person. If such person does not execute and deliver the Restricted Stock Purchase Agreement along with full payment (made in accordance with
Section 8.1 hereof) for the Shares to the Company within such thirty (30) days, then such Restricted Stock Award will terminate, unless otherwise determined by the Committee. 

  
 6 

 6.2 Purchase Price. The Purchase Price of Shares sold pursuant to a
Restricted Stock Award will be determined by the Committee and if Section 25102(o) is applicable, then the Purchase Price will be at least equal to eighty-five percent (85%) of the Fair Market Value of the Shares on the date the Restricted
Stock Award is granted or at the time the purchase is consummated, except in the case of a sale to a Ten Percent Stockholder, in which case the Purchase Price will be one hundred percent (100%) of the Fair Market Value on the date the Restricted
Stock Award is granted or at the time the purchase is consummated. 
 6.3 Restrictions. Restricted Stock Awards may be
subject to the restrictions set forth in Section 11 hereof or such other restrictions determined by the Committee or required by law (including the restrictions required by Section 25102(o) when intended to apply). 

7. PAYMENT FOR SHARE PURCHASES. 

7.1 Payment. Payment for Shares purchased pursuant to this Plan may be made in cash (including by check) or, where
expressly approved for the Participant by the Committee and permitted by law: 
 (a) by cancellation of indebtedness of the Company owed to
the Participant; 
 (b) by surrender of shares that: (i) either (A) have been paid for within the meaning of SEC Rule 144
(and, if such shares were purchased from the Company by use of a promissory note, such note has been fully paid with respect to such shares) or (B) were obtained by Participant in the public market and (ii) are clear of all liens, claims,
encumbrances or security interests; 
 (c) by tender of a full recourse promissory note having such terms as may be approved by the
Committee and bearing interest at a rate sufficient to avoid (i) imputation of income under Sections 483 and 1274 of the Code and (ii) unfavorable accounting treatment as determined by the Committee in its sole discretion; provided,
however, that Participants who are not employees or directors of the Company will not be entitled to purchase Shares with a promissory note unless the note is adequately secured by collateral other than the Shares; provided, further, that the
portion of the Exercise Price or Purchase Price, as the case may be, equal to the par value of the Shares must be paid in cash or other legal consideration permitted by Delaware General Corporation Law, to the extent that Delaware General
Corporation Law is applicable; 
 (d) by waiver of compensation due or accrued to the Participant from the Company for services rendered;

 (e) with respect only to purchases upon exercise of an Option, and provided that a public market for the Company’s stock exists:

 (i) through a “same day sale” commitment from the Participant and a broker-dealer that is a member of the National Association
of Securities Dealers (an “NASD Dealer”) whereby the Participant irrevocably elects to exercise the Option and to sell a portion of the Shares so purchased sufficient to pay the total Exercise Price, and whereby the NASD
Dealer irrevocably commits upon receipt of such Shares to forward the total Exercise Price directly to the Company; or 

  
 7 

 (ii) through a “margin” commitment from the Participant and an NASD Dealer
whereby the Participant irrevocably elects to exercise the Option and to pledge the Shares so purchased to the NASD Dealer in a margin account as security for a loan from the NASD Dealer in the amount of the total Exercise Price, and whereby the
NASD Dealer irrevocably commits upon receipt of such Shares to forward the total Exercise Price directly to the Company; or 
 (f) by any
combination of the foregoing. 
 7.2 Loan Guarantees. The Committee may, in its sole discretion, elect to assist the
Participant in paying for Shares purchased under this Plan by authorizing a guarantee by the Company of a third-party loan to the Participant. 

8. WITHHOLDING TAXES. 

8.1 Withholding Generally. Whenever Shares are to be issued in satisfaction of Awards granted under this Plan, the Company
may require the Participant to remit to the Company an amount sufficient to satisfy any foreign, federal, state and local tax withholding requirements prior to the delivery of any certificate or certificates for such Shares. Whenever, under this
Plan, payments in satisfaction of Awards are to be made in cash by the Company, such payment will be net of an amount sufficient to satisfy any foreign, federal, state, and local tax withholding requirements. 

8.2 Stock Withholding. When, under applicable tax laws, a Participant incurs tax liability in connection with the exercise
or vesting of any Award that is subject to tax withholding and the Participant must pay the Company the amount required to be withheld, the Committee may in its sole discretion allow the Participant to satisfy the minimum tax withholding obligation
by electing to have the Company withhold from the Shares to be issued that minimum number of Shares having a Fair Market Value equal to the minimum amount required to be withheld, determined on the date that the amount of tax to be withheld is to be
determined; but in no event will the Company withhold Shares if such withholding would result in adverse accounting consequences to the Company. Any election by any Participant to have Shares withheld for this purpose must be in writing on a form
made in accordance with the requirements established by the Committee for such election. 
 9. PRIVILEGES OF STOCK
OWNERSHIP. 
 9.1 Voting and Dividends. No Participant will have any of the rights of a stockholder with respect
to any Shares until the date of issuance of Shares to the Participant as recorded in the stockholder records of the Company. After Shares are issued to the Participant, the Participant will be a stockholder and have all the rights of a stockholder
with respect to such Shares, including the right to vote and receive all dividends or other distributions made or paid with respect to such Shares; provided, that if such Shares are Restricted Stock, then any new, additional or different securities
the Participant may become entitled to receive with respect to such Shares by virtue of a stock dividend, stock split or any other change in the corporate or capital structure of the Company will be subject to the same restrictions as the Restricted
Stock. The Participant will have no right to retain such stock dividends or stock distributions with respect to Unvested Shares that are repurchased pursuant to Section 11 hereof. To the extent required, the Company will comply with
Section 260.140.1 of Title 10 of the California Code of Regulations with respect to the voting rights of common stock. 

  
 8 

 9.2 Financial Statements. For each Participant who holds an Award the
Company exempts from qualification under Section 25102(o), and for whom such is required by Section 25102(o), the Company will provide financial statements annually during the period such Participant holds such Award, or as otherwise
required under Section 260.140.46 of Title 10 of the California Code of Regulations. Notwithstanding the foregoing, the Company will not be required to provide such financial statements to those Participants who are key employees whose
services in connection with the Company assure them access to equivalent information. 
 10. TRANSFERABILITY.
Except as permitted by the Committee, Awards granted under this Plan, and any interest therein, will not be transferable or assignable by Participant, other than by will or by the laws of descent and distribution, and, with respect to NQSOs, by
instrument to an inter vivos or testamentary trust in which the Options are to be passed to beneficiaries upon the death of the trustor (settlor), or by gift to “immediate family” as that term is defined in 17 C.F.R. 240.16a-1(e), and may not be made subject to execution, attachment or similar process. During the lifetime of the Participant an Award will be exercisable only by the Participant or Participant’s legal
representative and any elections with respect to an Award may be made only by the Participant or Participant’s legal representative. 

11. RESTRICTIONS ON SHARES. 

11.1 Right of First Refusal. At the discretion of the Committee, the Company may reserve to itself and/or its assignee(s)
in the Award Agreement a right of first refusal to purchase all Shares that a Participant (or a subsequent transferee) may propose to transfer to a third party, except as prohibited by Section 25102(o) when Section 25102(o) is intended to
apply, provided that such right of first refusal terminates upon the Company’s initial public offering of common stock pursuant to an effective registration statement filed under the Securities Act. 

11.2 Right of Repurchase. At the discretion of the Committee, the Company may reserve to itself and/or its assignee(s) in
the Award Agreement a right to repurchase Unvested Shares held by a Participant for cash and/or cancellation of purchase money indebtedness owed to the Company by the Participant following such Participant’s Termination at any time within the
later of ninety (90) days after the Participant’s Termination Date and the date the Participant purchases such Shares under the Plan at the Participant’s Exercise Price or Purchase Price, as the case may be, provided that to the
extent Section 25102(o) is intended to apply, unless the Participant is an officer, director or consultant of the Company or of a Parent or Subsidiary, such right of repurchase lapses at the rate of no less than twenty percent (20%) per year
over five (5) years from: (a) the date of grant of the Option or (b) in the case of Restricted Stock, the date the Participant purchases the Shares. 

12. CERTIFICATES. All certificates for Shares or other securities delivered under this Plan will be subject to
such stock transfer orders, legends and other restrictions as the Committee may deem necessary or advisable, including restrictions under any applicable federal, state or foreign securities law, or any rules, regulations and other requirements of
the SEC or any stock exchange or automated quotation system upon which the Shares may be listed or quoted. 

  
 9 

 13. ESCROW; PLEDGE OF SHARES. To enforce any restrictions on a
Participant’s Shares set forth in Section 11 hereof, the Committee may require the Participant to deposit all certificates representing Shares, together with stock powers or other instruments of transfer approved by the Committee,
appropriately endorsed in blank, with the Company or an agent designated by the Company to hold in escrow until such restrictions have lapsed or terminated. The Committee may cause a legend or legends referencing such restrictions to be placed on
the certificates. Any Participant who is permitted to execute a promissory note as partial or full consideration for the purchase of Shares under this Plan will be required to pledge and deposit with the Company all or part of the Shares so
purchased as collateral to secure the payment of Participant’s obligation to the Company under the promissory note; provided, however, that the Committee may require or accept other or additional forms of collateral to secure the payment of
such obligation and, in any event, the Company will have full recourse against the Participant under the promissory note notwithstanding any pledge of the Participant’s Shares or other collateral. In connection with any pledge of the Shares,
Participant will be required to execute and deliver a written pledge agreement in such form as the Committee will from time to time approve. The Shares purchased with the promissory note may be released from the pledge on a pro rata basis as the
promissory note is paid. 
 14. EXCHANGE AND BUYOUT OF AWARDS. The repricing of Options is permitted without
prior stockholder approval. The Committee may, at any time or from time to time, authorize the Company, with the consent of the respective Participants, to issue new Awards in exchange for the surrender and cancellation of any, or all, outstanding
Awards. The Committee may at any time buy from a Participant an Award previously granted with payment in cash, shares of common stock of the Company (including Restricted Stock) or other consideration, based on such terms and conditions as the
Committee and the Participant may agree. 
 15. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. Although this
Plan is intended to be a written compensatory benefit plan within the meaning of Rule 701 promulgated under the Securities Act, grants may be made pursuant to this Plan which do not qualify for exemption under Rule 701 or Section 25102(o).
Any requirement of this Plan which is required in law only because of Section 25102(o) need not apply if the Committee so determines or Section 25102(o) is actually inapplicable. An Award will not be effective unless such Award is in
compliance with all applicable federal and state securities laws, rules and regulations of any governmental body, and the requirements of any stock exchange or automated quotation system upon which the Shares may then be listed or quoted, as they
are in effect on the date of grant of the Award and also on the date of exercise or other issuance. Notwithstanding any other provision in this Plan, the Company will have no obligation to issue or deliver certificates for Shares under this Plan
prior to (a) obtaining any approvals from governmental agencies that the Company determines are necessary or advisable, and/or (b) compliance with any exemption, completion of any registration or other qualification of such Shares under
any state or federal law or ruling of any governmental body that the Company determines to be necessary or advisable. The Company will be under no obligation to register the Shares with the SEC or to effect compliance with the exemption,
registration, qualification or listing requirements of any state securities laws, stock exchange or automated quotation system, and the Company will have no liability for any inability or failure to do so. 

  
 10 

 16. NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Award
granted under this Plan will confer or be deemed to confer on any Participant any right to continue as an employee, director or consultant with, the Company or any Parent or Subsidiary or limit in any way the right of the Company or any Parent or
Subsidiary to terminate such service at any time, with or without Cause. 
 17. CORPORATE TRANSACTIONS. 

17.1 Assumption or Replacement of Awards by Successor or Acquiring Company. In the event of (a) a dissolution
or liquidation of the Company, (b) any reorganization, consolidation, merger or similar transaction or series of related transactions (each, a “combination transaction”)) in which the Company is a constituent corporation
or is a party if, as a result of such combination transaction, the voting securities of the Company that are outstanding immediately prior to the consummation of such combination transaction (other than any such securities that are
held by an “Acquiring Stockholder”, as defined below) do not represent, or are not converted into, securities of the surviving corporation of such combination transaction (or such surviving corporation’s parent corporation if the
surviving corporation is owned by the parent corporation) that, immediately after the consummation of such combination transaction, together possess at least fifty percent (50%) of the total voting power of all securities of such surviving
corporation (or its parent corporation, if applicable) that are outstanding immediately after the consummation of such combination transaction, including securities of such surviving corporation (or its parent corporation, if applicable) that are
held by the Acquiring Stockholder; or (c) a sale of all or substantially all of the assets of the Company, that is followed by the distribution of the proceeds to the Company’s stockholders, any of the outstanding Awards, or all
outstanding Awards, may be assumed, converted or replaced by the successor or acquiring corporation (if any), which assumption, conversion or replacement will be binding on all Participants. In the alternative, the successor or acquiring corporation
may substitute equivalent Awards or provide substantially similar consideration to Participants as was provided to stockholders of the Company (after taking into account the existing provisions of the Awards). The successor or acquiring corporation
may also substitute by issuing, in place of outstanding Shares of the Company held by the Participant, substantially similar shares or other property subject to repurchase restrictions and other provisions no less favorable to the Participant than
those which applied to such outstanding Shares immediately prior to such transaction described in this Section 17.1. For purposes of this Section 17.1, an “Acquiring Stockholder” means a stockholder or stockholders
of the Company that (a) merges or combines with the Company in such combination transaction or (b) owns or controls a majority of another corporation that merges or combines with the Corporation in such combination transaction. In the
event such successor or acquiring corporation (if any) refuses to assume, convert, replace or substitute Awards, as provided above, pursuant to a transaction described in this Section 17.1, then notwithstanding any other provision in this Plan
to the contrary, those Awards that are not assumed, converted, replaced or substituted will expire with respect to unissued Shares subject to such Awards, at such time and on such conditions as the Board will determine, but no later than immediately
prior to consummation of such transaction.  
 17.2 Other Treatment of Awards. Notwithstanding the provisions of
Section 17.1, in the event of the occurrence of any transaction described in Section 17.1 hereof, all outstanding Awards will be treated as provided in the applicable agreement or plan of reorganization, merger, consolidation, dissolution,
liquidation or sale of assets. 

  
 11 

 17.3 Assumption of Awards by the Company. The Company, from time to
time, also may substitute or assume outstanding awards granted by another company, whether in connection with an acquisition of such other company or otherwise, by either (a) granting an Award under this Plan in substitution of such other
company’s award or (b) assuming such award as if it had been granted under this Plan if the terms of such assumed award could be applied to an Award granted under this Plan. Such substitution or assumption will be permissible if the holder
of the substituted or assumed award would have been eligible to be granted an Award under this Plan if the other company had applied the rules of this Plan to such grant. In the event the Company assumes an award granted by another company, the
terms and conditions of such award will remain unchanged (except that the exercise price and the number and nature of shares issuable upon exercise of any such award that is an “incentive stock option” under Section 422 of the Code
will be adjusted pursuant to Section 424(a) of the Code to preserve such status). If the Company elects to grant a new Option rather than assuming an existing option, such new Option may be granted with a similarly adjusted Exercise Price. 

18. ADOPTION AND STOCKHOLDER APPROVAL. This Plan takes effect on the Date. To permit the grant of ISOs and the
coverage of Section 25102(o) when desirable, this Plan must be approved by the stockholders of the Company (excluding Shares issued pursuant to this Plan from the determination of whether such approval has been obtained), consistent with
applicable laws, within twelve (12) months before or after the date the Plan is approved by the Board. Commencing on the Effective Date, the Board may grant Awards pursuant to this Plan; provided, however, that: (a) no Option may be
exercisable prior to initial stockholder approval of this Plan; (b) no Option granted pursuant to an increase in the number of Shares approved by the Board shall be exercisable prior to the time such increase has been approved by the
stockholders of the Company; and (c) with respect to Awards to which Section 25102(o) is intended to apply if the necessary stockholder approval is not obtained within the required time period, then all such Awards granted hereunder shall
automatically expire, any Shares issued pursuant to any such Award shall automatically be canceled and any purchase of such Shares shall be rescinded. 

19. TERM OF PLAN/GOVERNING LAW. Unless earlier terminated as provided herein, this Plan will terminate ten
(10) years from the Effective Date or, if earlier, the date of stockholder approval. This Plan and all agreements hereunder shall be governed by and construed in accordance with the laws of the State of California. 

20. AMENDMENT OR TERMINATION OF PLAN. Subject to Section 5.9 hereof, the Board may at any time terminate or amend
this Plan in any respect, including without limitation amendment of any form of Award Agreement or instrument to be executed pursuant to this Plan; provided, however, that the Board will not, without the approval of the stockholders of the Company,
amend this Plan in any manner that requires such stockholder approval pursuant to Section 25102(o) or the Code or the regulations promulgated thereunder as such provisions apply to ISO plans. 

21. NONEXCLUSIVITY OF THE PLAN. Neither the adoption of this Plan by the Board, the submission of this Plan to the
stockholders of the Company for approval, nor any provision of this Plan will be construed as creating any limitations on the power of the Board to adopt such additional compensation arrangements as it may deem desirable, including, without
limitation, the granting of stock options and other equity awards otherwise than under this Plan, and such arrangements may be either generally applicable or applicable only in specific cases.

 Attachment 2 to Notice of Stock Option Grant 

BILL.COM, INC. 
 2006
EQUITY INCENTIVE PLAN 
 STOCK OPTION AGREEMENT 

1. GRANT OF OPTION. Pursuant to the Notice of Stock Option Grant (the “Grant Notice”) and this
Stock Option Agreement, Bill.com, Inc.(the “Company”) has granted to the Participant an option (the “Option”) to purchase up to the total number of shares of Common Stock of the Company set forth in
the Grant Notice (the “Shares”) at the Exercise Price Per Share set forth in the Grant Notice (the “Exercise Price”), subject to all of the terms and conditions of the Grant Notice, this Stock Option
Agreement and the Plan. Capitalized terms not defined herein shall have the meanings ascribed to them in the Company’s 2006 Equity Incentive Plan, as may be amended from time to time (the “Plan”), or in the Grant Notice,
as applicable. If designated as an Incentive Stock Option in the Grant Notice, the Option is intended to qualify as an “incentive stock option” (an “ISO”) within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the “Code”). 
 2. VESTING AND EXERCISE. 

2.1 Vesting Period of Option. The Option will become vested during its term as to portions of the Shares in accordance
with the Vesting Schedule set forth in the Grant Notice. If application of the applicable vesting fraction causes a fractional share, such share shall be rounded down to the nearest whole share for each month except for the last month in such
vesting period, at the end of which last month the Option shall become exercisable for the full remainder of the Shares.    Shares that are vested pursuant to the Vesting Schedule set forth in the Grant Notice are
“Vested Shares.” Shares that are not vested pursuant to the Vesting Schedule set forth in the Grant Notice are “Unvested Shares.” 

2.2 Exercise Period of Option. The Option will become exercisable during its term as to all Shares that are or become
Vested Shares. In addition, if the Exercise Schedule contained in the Grant Notice indicates that “Early Exercise” of this Option is permitted, this Option may be exercised as to all or a portion of the Shares, including Unvested Shares,
at any time prior to Participant’s Termination Date (any such exercise that includes Unvested Shares, an “Early Exercise”). If Participant elects to make an Early Exercise of this Option, the Company, or its assignee, shall have the
option to repurchase Participant’s Unvested Shares on the terms and conditions set forth in the Exercise Agreement (the “Repurchase Option”) if Participant is Terminated (as defined in the Plan) for any reason, or no reason, including
without limitation Participant’s death, Disability (as defined in the Plan), voluntary resignation or termination by the Company with or without Cause. A partial Early Exercise of this Option shall be deemed to cover first all Vested Shares and
then the earliest vesting installment of Unvested Shares. 
 2.3 Expiration. The Option shall expire on the Option
Expiration Date set forth in the Grant Notice or earlier as provided in Section 3 below or pursuant to Section 5.6 of the Plan. 

3. TERMINATION. 

3.1 Termination for Any Reason Except Death, Disability or Cause. If Participant is Terminated for any reason, except
death, Disability or for Cause, the Option, to the extent (and only to the extent) that it would have been exercisable by Participant on the Termination Date, may be exercised by Participant no later than three months after the Termination Date, but
in any event no later than the Expiration Date. 

  
 1 

 3.2 Termination Because of Death or Disability. If Participant is
Terminated because of death or Disability of Participant (or Participant dies within three (3) months of Termination when Termination is for any reason other than Participant’s Disability or for Cause), the Option, to the extent that it is
exercisable by Participant on the Termination Date, may be exercised by Participant (or Participant’s legal representative) no later than twelve (12) months after the Termination Date, but in any event no later than the Expiration Date.
Any exercise beyond (i) three (3) months after the Termination Date when the Termination is for any reason other than the Participant’s death or disability, within the meaning of Section 22(e)(3) of the Code; or (ii) twelve
(12) months after the Termination Date when the termination is for Participant’s disability, within the meaning of Section 22(e)(3) of the Code, is deemed to be an NQSO. 

3.3 Termination for Cause.    If the Participant is Terminated for Cause, then the Participant’s
Options shall expire on such Participant’s Termination Date and the Participant must exercise such Participant’s Options, if at all, by no later than such Termination Date, but not to an extent greater than such Options are exercisable as
to Vested Shares upon the Termination Date; provided, however, that the Committee may elect waive or modify such conditions. 
 3.4
No Obligation to Employ. Nothing in the Plan or this Stock Option Agreement shall confer on Participant any right to continue in the employ of, or other relationship with, the Company or any Parent or Subsidiary of the Company, or
limit in any way the right of the Company or any Parent or Subsidiary of the Company to terminate Participant’s employment or other relationship at any time, with or without Cause. 

4. MANNER OF EXERCISE. 

4.1 Stock Option Exercise Agreement. To exercise the Option, Participant (or in the case of exercise after
Participant’s death or incapacity, Participant’s executor, administrator, heir or legatee, as the case may be) must deliver to the Company an executed stock option exercise agreement (with Notice of Exercise of Stock Option) in the form
attached hereto as Exhibit A, or in such other form as may be approved by the Committee from time to time (the “Exercise Agreement”), which shall set forth, inter alia,
(i) Participant’s election to exercise the Option, (ii) the number of Shares being purchased, (iii) any restrictions imposed on the Shares and (iv) any representations, warranties and agreements regarding Participant’s
investment intent and access to information as may be required by the Company to comply with applicable securities laws. If someone other than Participant exercises the Option, then such person must submit documentation reasonably acceptable to the
Company verifying that such person has the legal right to exercise the Option and such person shall be subject to all of the restrictions contained herein as if such person were the Participant. 

4.2 Limitations on Exercise. The Option may not be exercised unless such exercise is in compliance with all applicable
federal and state securities laws, as they are in effect on the date of exercise. The Option may not be exercised as to fewer than one hundred (100) Shares unless it is exercised as to all Shares as to which the Option is then exercisable. 

4.3 Payment. The Exercise Agreement shall be accompanied by full payment of the Exercise Price for the shares being
purchased in cash (by check), or where permitted by law: 
 (a) by cancellation of indebtedness of the Company to the Participant; 

(b) by waiver of compensation due or accrued to Participant for services rendered; 

(c) any other form of consideration approved by the Committee; or 

(d) by any combination of the foregoing. 

  
 2 

 4.4 Tax Withholding. Prior to the issuance of the Shares upon exercise
of the Option, Participant must pay or provide for any applicable foreign, federal, state and local withholding obligations of the Company. If the Committee permits, Participant may provide for payment of withholding taxes upon exercise of the
Option by requesting that the Company retain the minimum number of Shares with a Fair Market Value equal to the minimum amount of taxes required to be withheld; but in no event will the Company withhold Shares if such withholding would result in
adverse accounting consequences to the Company. In such case, the Company shall issue the net number of Shares to the Participant by deducting the Shares retained from the Shares issuable upon exercise. 

4.5 Issuance of Shares. Provided that the Exercise Agreement and payment are in form and substance satisfactory to counsel
for the Company, the Company shall issue the Shares registered in the name of Participant, Participant’s authorized assignee, or Participant’s legal representative, and shall deliver certificates representing the Shares with the
appropriate legends affixed thereto. 
 5. NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES. If the Option is
an ISO, and if Participant sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (i) the date two (2) years after the Date of Grant, and (ii) the date one (1) year after transfer
of such Shares to Participant upon exercise of the Option, Participant shall immediately notify the Company in writing of such disposition. Participant agrees that Participant may be subject to income tax withholding by the Company on the
compensation income recognized by Participant from the early disposition by payment in cash or out of the current wages or other compensation payable to Participant. 

6.
COMPLIANCE WITH LAWS AND REGULATIONS. Unless expressly stated otherwise in the resolutions
approving grant of this Option, the grant of this Option, and its terms, are intended to comply with Section 25102(o) of the California Corporations Code and to avoid the application of Section 409A of the Code. Any provision of this Stock
Option Agreement which is inconsistent with Section 25102(o) or any regulations thereunder shall, without further act or amendment by Participant, the Company or the Committee, be automatically reformed so as to comply with the requirements of
Section 25102(o) and any regulations relating thereto. In addition, to the extent that Section 409A of the Code applies to this Option, the Committee may at any time, acting in its sole discretion, amend any provision of this Option so as
to cause Section 409A not to apply to this Option without any action or other consent of Participant. The exercise of the Option and the issuance and transfer of Shares shall be subject to compliance by the Company and Participant with
all applicable requirements of federal and state securities laws and with all applicable requirements of any stock exchange on which the Company’s Common Stock may be listed at the time of such issuance or transfer. Participant understands that
the Company is under no obligation to register or qualify the Shares with the SEC, any state securities commission or any stock exchange to effect such compliance. 

7. NONTRANSFERABILITY OF OPTION. The Option may
not be transferred in any manner other than by will or by the laws of descent and distribution, and, with respect to NQSOs, by instrument to an inter vivos or testamentary trust in which the options are to be passed to beneficiaries upon the death
of the trustor (settlor), or by gift to a “family member” as that term is defined in 17 C.F.R. 230.701, and may be exercised during the lifetime of Participant only by Participant or in the event of Participant’s incapacity, by
Participant’s legal representative. The terms of the Option shall be binding upon the executors, administrators, successors and assigns of Participant. 

  
 3 

 8. COMPANY’S REPURCHASE OPTION FOR UNVESTED SHARES. The
Company, or its assignee, shall have the option to repurchase Participant’s Unvested Shares (as defined in Section 2.2 of this Agreement) on the terms and conditions set forth in the Exercise Agreement (the
“Repurchase Option”) if Participant is Terminated (as defined in the Plan) for any reason, or no reason, including without limitation Participant’s death, Disability (as defined in the
Plan), voluntary resignation or termination by the Company with or without Cause. Notwithstanding the foregoing, the Company shall retain the Repurchase Option for Unvested Shares only as to that number of Unvested Shares (whether or not exercised)
that exceeds the number of shares which remain unexercised. 
 9. COMPANY’S RIGHT OF FIRST
REFUSAL. Before any Vested Shares held by Participant or any transferee of such Vested Shares may be sold or otherwise transferred (including without limitation a transfer by gift or operation of law), the Company and/or its assignee(s)
shall have an assignable right of first refusal to purchase the Vested Shares to be sold or transferred on the terms and conditions set forth in the Exercise Agreement (the “Right of First Refusal”). The Company’s Right
of First Refusal will terminate when the Company’s securities become publicly traded. 
 10. U.S. TAX
CONSEQUENCES. Set forth below is a brief summary as of the Effective Date of the Plan of some of the federal tax consequences of exercise of the Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE
TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. PARTICIPANT SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THE OPTION OR DISPOSING OF THE SHARES. 

10.1 Exercise of ISO. If the Option qualifies as an ISO, there will be no regular federal income tax liability upon the
exercise of the Option, although the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price will be treated as a tax preference item for federal alternative minimum tax purposes and may subject the
Participant to the alternative minimum tax in the year of exercise. 
 10.2 Exercise of Nonqualified Stock Option. If
the Option does not qualify as an ISO, there may be a regular federal income tax liability upon the exercise of the Option. Participant will be treated as having received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price. If Participant is a current or former employee of the Company, the Company may be required to withhold from Participant’s compensation or
collect from Participant and pay to the applicable taxing authorities an amount equal to a percentage of this compensation income at the time of exercise. 

10.3 Disposition of Shares. The following tax consequences may apply upon disposition of the Shares. 

(a) Incentive Stock Options. If the Shares are held for more than twelve (12) months after the date of purchase of the Shares
pursuant to the exercise of an ISO and are disposed of more than two (2) years after the Date of Grant, any gain realized on disposition of the Shares will be treated as long term capital gain for federal income tax purposes. If Vested Shares
purchased under an ISO are disposed of within the applicable one (1) year or two (2) year period, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates in the year of the
disposition) to the extent of the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price. To the extent the Shares were exercised prior to vesting coincident with the filing of an 83(b) Election, the
amount taxed because of a disqualifying disposition will be based upon the excess, if any, of the fair market value on the date of vesting over the exercise price. 

  
 4 

 (b) Nonqualified Stock Options. If the Shares are held for more than twelve
(12) months after the date of purchase of the Shares pursuant to the exercise of an NQSO, any gain realized on disposition of the Shares will be treated as long term capital gain. 

(c) Withholding. The Company may be required to withhold from the Participant’s compensation or collect from the Participant and
pay to the applicable taxing authorities an amount equal to a percentage of this compensation income. 
 10.4
Section 83(b) Election for Unvested Shares Purchased by Early Exercise. With respect to Unvested Shares which are subject to the Repurchase Option, unless an election is filed by the Participant
with the Internal Revenue Service (and, if necessary, the proper state taxing authorities), within 30 days of the purchase of the Unvested Shares, electing pursuant to Section 83(b) of the Code (and similar state tax provisions, if applicable)
to be taxed currently on any difference between the Exercise Price of the Unvested Shares and their Fair Market Value on the date of purchase, there may be a recognition of taxable income (including, where applicable, alternative minimum taxable
income) to the Participant, measured by the excess, if any, of the Fair Market Value of the Unvested Shares at the time they cease to be Unvested Shares, over the Exercise Price of the Unvested Shares. 

11. PRIVILEGES OF STOCK OWNERSHIP. Participant shall not have any of the rights of a stockholder with respect to
any Shares until the Shares are issued to Participant. 
 12. INTERPRETATION. Any dispute regarding the
interpretation of this Agreement shall be submitted by Participant or the Company to the Committee for review. The resolution of such a dispute by the Committee shall be final and binding on the Company and Participant. 

13. ENTIRE AGREEMENT. The Plan is incorporated herein by reference. This Stock Option Agreement, the Grant Notice,
the Plan and the exhibits to each of the foregoing constitute the entire agreement of the parties and supersede all prior undertakings and agreements with respect to the subject matter hereof.

 16. SECTION 409A Participant acknowledges that, under Section 409A
of the Code, receipt of a stock option with an exercise price per share that is less than the fair market value of the stock subject to the option at the time of grant can result in significant adverse tax consequences to the Participant, including
without limitation the imputation of taxable income to the Participant on the difference between the exercise price and fair market value as the option vests and the imposition of an additional excise tax on the Participant. The Company does not
make any representation to Participant that the Exercise Price of this Option was equal to the fair market value per share of the Shares as of the Date of Grant. Participant acknowledges and agrees that neither the Company, nor its officers,
directors, stockholders, employees, attorneys, agents, successors or assigns, shall have any liability to Participant should it be determined hereafter that the Exercise Price of this Option is less than the fair market value per share of the Shares

Participant is under no obligation to accept this Option.

18. ACCEPTANCE. Participant hereby acknowledges receipt of a copy of the Plan and this Stock Option Agreement.
Participant has read and understands the terms and provisions thereof, and accepts the Option subject to all the terms and conditions of the Plan and this Stock Option Agreement. Participant acknowledges that there may be adverse tax consequences

 STOCK OPTION EXERCISE AGREEMENT 

1. Exercise of Option. Pursuant to the exercise of that certain option (the “Option”) granted to
the Purchaser (the “Purchaser”) named on the Notice of Exercise of Stock Option (the “Exercise Notice”) to which this Stock Option Exercise Agreement is attached, under the 2006 Equity Incentive Plan,
as amended (the “Plan”) of Bill.com, Inc., a Delaware corporation (the “Company”) and subject to the terms and conditions of the Exercise Notice and this Stock Option Exercise Agreement (the
“Exercise Agreement”), the Purchaser hereby purchases from the Company, and the Company hereby sells to the Purchaser, the Number of Shares Being Purchased (set forth in the Exercise Notice) of the Company’s Common Stock
at the Exercise Price per Share set forth in the Exercise Notice. As used in this Exercise Agreement, the term “Shares” refers to the Shares purchased under the Exercise Notice and this Exercise Agreement and includes all
securities received (i) in replacement of the Shares, (ii) as a result of stock dividends or stock splits with respect to the Shares, and (iii) all securities received in replacement of the Shares in a merger, recapitalization,
reorganization or similar corporate transaction. Capitalized terms not defined herein shall have the meanings ascribed to them in the Plan or the Exercise Notice. 

2. Delivery. 

2.1 Deliveries by Purchaser. The Purchaser hereby delivers to the Company (i) the Exercise Notice, (ii) the Stock
Powers, (iii) if applicable, the Spouse Consent, and (iv) the Total Exercise Price and payment or other provision for any applicable tax obligations. 

2.2 Deliveries by the Company. Upon its receipt of the Exercise Price, payment or other provision for any applicable tax
obligations and all the documents to be executed and delivered by the Purchaser to the Company under this Section 2, the Company will issue a duly executed stock certificate evidencing the Shares in the name of the Purchaser to be placed in
escrow as provided in Section 11 until expiration or termination of the Company’s Right of First Refusal and, if applicable, Repurchase Option, described in Sections 8 and 9 below. 

3. Representations and Warranties of Purchaser. Purchaser represents and warrants to the Company that: 

3.1 Agrees to Terms of the Plan. Purchaser has received a copy of the Plan and the Stock Option Agreement, has read and
understands the terms of the Plan, , the Grant Notice, the Stock Option Agreement (both as defined in the Exercise Notice) and this Exercise Agreement, and agrees to be bound by their terms and conditions. Purchaser acknowledges that there may be
adverse tax consequences upon exercise of the Option or disposition of the Shares, and that Purchaser should consult a tax adviser prior to such exercise or disposition. 

3.2 Purchase for Own Account for Investment. Purchaser is purchasing the Shares for Purchaser’s own account for investment
purposes only and not with a view to, or for sale in connection with, a distribution of the Shares within the meaning of the Securities Act. Purchaser has no present intention of selling or otherwise disposing of all or any portion of the Shares and
no one other than Purchaser has any beneficial ownership of any of the Shares. 

  
 1 

 3.3 Access to Information. Purchaser has had access to all information
regarding the Company and its present and prospective business, assets, liabilities and financial condition that Purchaser reasonably considers important in making the decision to purchase the Shares, and Purchaser has had ample opportunity to ask
questions of the Company’s representatives concerning such matters and this investment. 
 3.4 Understanding of Risks.
Purchaser is fully aware of: (i) the highly speculative nature of the investment in the Shares; (ii) the financial hazards involved; (iii) the lack of liquidity of the Shares and the restrictions on transferability of the Shares
(e.g., that Purchaser may not be able to sell or dispose of the Shares or use them as collateral for loans); (iv) the qualifications and backgrounds of the management of the Company; and (v) the tax consequences of investment in the
Shares. Purchaser is capable of evaluating the merits and risks of this investment, has the ability to protect Purchaser’s own interests in this transaction and is financially capable of bearing a total loss of this investment. 

3.5 No General Solicitation. At no time was Purchaser presented with or solicited by any publicly issued or circulated newspaper,
mail, radio, television or other form of general advertising or solicitation in connection with the offer, sale and purchase of the Shares. 

4. Compliance with Laws and Regulations. Purchaser understands and acknowledges that the Shares have not been registered
with the SEC under the Securities Act and that, notwithstanding any other provision of the Stock Option Agreement to the contrary, the exercise of any rights to purchase any Shares is expressly conditioned upon compliance with the Securities Act and
all applicable state securities laws. Purchaser agrees to cooperate with the Company to ensure compliance with such laws. UNLESS EXPRESSLY STATED OTHERWISE IN THE RESOLUTIONS APPROVING THE GRANT OF THE OPTION (OR OPTIONS) BEING EXERCISED PURSUANT TO
THIS EXERCISE AGREEMENT, THE PLAN, THE GRANT NOTICE, THE STOCK OPTION AGREEMENT, AND THIS EXERCISE AGREEMENT ARE INTENDED TO COMPLY WITH SECTION 25102(o) OF THE CALIFORNIA CORPORATIONS CODE AND TO AVOID THE APPLICATION OF SECTION 409A OF THE CODE.
ANY PROVISION OF THIS EXERCISE AGREEMENT THAT IS INCONSISTENT SECTION 25102(o) SHALL, WITHOUT FURTHER ACT OR AMENDMENT BY THE PARTICIPANT, THE COMPANY OR THE BOARD, BE AUTOMATICALLY REFORMED SO AS TO COMPLY WITH THE REQUIREMENTS OF SECTION
25102(o).    IN ADDITION, TO THE EXTENT THAT SECTION 409A OF THE CODE APPLIES, THE COMPANY MAY AT ANY TIME, ACTING IN ITS SOLE DISCRETION, AMEND ANY PROVISION OF THIS EXERCISE AGREEMENT SO AS TO CAUSE SECTION 409A NOT TO APPLY TO
THIS EXERCISE AGREEMENT WITHOUT ANY ACTION OR OTHER CONSENT OF PARTICIPANT. THE SALE OF THE SECURITIES THAT ARE THE SUBJECT OF THIS EXERCISE AGREEMENT, IF NOT YET QUALIFIED WITH THE CALIFORNIA COMMISSIONER OF CORPORATIONS AND NOT EXEMPT FROM SUCH
QUALIFICATION, IS SUBJECT TO SUCH QUALIFICATION, AND THE ISSUANCE OF SUCH SECURITIES, AND THE RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO SUCH QUALIFICATION IS UNLAWFUL UNLESS THE SALE IS EXEMPT. THE RIGHTS OF THE PARTIES TO THIS
EXERCISE AGREEMENT ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED OR AN EXEMPTION BEING AVAILABLE. 
 5.
Restricted Securities. 
 5.1 No Transfer Unless Registered or Exempt. Purchaser understands that Purchaser may not
transfer any Shares unless such Shares are registered under the Securities Act or qualified under applicable state securities laws or unless, in the opinion of counsel to the Company, exemptions from such registration and qualification requirements
are available. Purchaser understands that only the Company may file a registration statement with the SEC and that the Company is under no obligation to do so with respect to the Shares. Purchaser has also been advised that exemptions from
registration and qualification may not be available or may not permit Purchaser to transfer all or any of the Shares in the amounts or at the times proposed by Purchaser. 

  
 2 

 5.2 SEC Rule 144. In addition, Purchaser has been advised that SEC
Rule 144 promulgated under the Securities Act, which permits certain limited sales of unregistered securities, is not presently available with respect to the Shares and, in any event, requires that the Shares be held for a minimum of one
(1) year, and in certain cases two (2) years, after they have been purchased and paid for (within the meaning of Rule 144). Purchaser understands that Rule 144 may indefinitely restrict transfer of the Shares so long as
Purchaser remains an “affiliate” of the Company or if “current public information” about the Company (as defined in Rule 144) is not publicly available. 

5.3 SEC Rule 701. The Shares are issued pursuant to SEC Rule 701 promulgated under the Securities Act and
may become freely tradeable by non-affiliates (under limited conditions regarding the method of sale) ninety (90) days after the first sale of Common Stock of the Company to the general public pursuant to
a registration statement filed with and declared effective by the SEC, subject to the lengthier market standoff agreement contained in Section 7 of this Exercise Agreement or any other agreement entered into by Purchaser. Affiliates must comply
with the provisions (other than the holding period requirements) of Rule 144. 
 6. Restrictions on Transfers. 

6.1 Disposition of Shares. Purchaser hereby agrees that Purchaser shall make no disposition of the Shares (other than as
permitted by this Exercise Agreement) unless and until: 
 (a) Purchaser shall have notified the Company of the proposed disposition and
provided a written summary of the terms and conditions of the proposed disposition; 
 (b) Purchaser shall have complied with all
requirements of this Exercise Agreement applicable to the disposition of the Shares; 
 (c) Purchaser shall have provided the Company with
written assurances, in form and substance satisfactory to counsel for the Company, that (i) the proposed disposition does not require registration of the Shares under the Securities Act or (ii) all appropriate actions necessary for
compliance with the registration requirements of the Securities Act or of any exemption from registration available under the Securities Act (including Rule 144) have been taken; and 

(d) Purchaser shall have provided the Company with written assurances, in form and substance satisfactory to the Company, that the proposed
disposition will not result in the contravention of any transfer restrictions applicable to the Shares pursuant to the provisions of the Regulations referred to in Section 4 hereof. 

6.2 Restriction on Transfer. Purchaser shall not transfer, assign, grant a lien or security interest in, pledge, hypothecate,
encumber or otherwise dispose of any of the Shares which are subject to the Company’s Right of First Refusal or Repurchase Option described below, except as permitted by this Exercise Agreement. 

6.3 Transferee Obligations. Each person (other than the Company) to whom the Shares are transferred by means of one of the
permitted transfers specified in this Exercise Agreement must, as a condition precedent to the validity of such transfer, acknowledge in writing to the Company that such person is bound by the provisions of this Exercise Agreement and that the
transferred Shares are subject to (i) the Company’s Right of First Refusal granted hereunder and (ii) the market stand-off provisions of Section 7 hereof, to the same extent such Shares
would be so subject if retained by the Purchaser. 

  
 3 

 7. Market Standoff Agreement. Purchaser agrees in connection
with any registration of the Company’s securities that, upon the request of the Company or the underwriters managing any public offering of the Company’s securities, Purchaser will not sell or otherwise dispose of any Shares without the
prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed one hundred eighty (180) days) after the effective date of such registration requested by such managing underwriters and
subject to all restrictions as the Company or the underwriters may specify. Purchaser further agrees to enter into any agreement reasonably required by the underwriters to implement the foregoing. 

8. Company’s Repurchase Option for Unvested Shares. The Company, or its assignee,
shall have the option to repurchase all or a portion of the Shares that are Unvested Shares (as defined in the Stock Option Agreement) on the terms and conditions set forth in this Section (the “Repurchase Option”) if
Purchaser is Terminated (as defined in the Plan) for any reason, or no reason, including without limitation, Purchaser’s death, Disability (as defined in the Plan), voluntary resignation or termination by the Company with or without Cause. 

8.1 Termination and Termination Date. In case of any dispute as to whether Purchaser is Terminated, the Committee shall have
discretion to determine whether Purchaser has been Terminated and the effective date of such Termination (the “Termination Date”). 

8.2 Exercise of Repurchase Option. At any time within ninety (90) days after the Purchaser’s Termination Date (or, in
the case of securities issued upon exercise of an Option after the Purchaser’s Termination Date, within ninety (90) days after the date of such exercise), the Company, or its assignee, may elect to repurchase any or all the Shares that are
Unvested Shares by giving Purchaser written notice of exercise of the Repurchase Option. 
 8.3 Calculation of Repurchase Price for
Unvested Shares. The Company or its assignee shall have the option to repurchase from Purchaser (or from Purchaser’s personal representative as the case may be) the Unvested Shares at the Purchaser’s Exercise Price,
proportionately adjusted for any stock split or similar change in the capital structure of the Company as set forth in Section 2.2 of the Plan (the “Repurchase Price”). 

8.4 Payment of Repurchase Price. The Repurchase Price shall be payable, at the option of the Company or its assignee, by check or
by cancellation of all or a portion of any outstanding purchase money indebtedness owed by Purchaser to the Company or such assignee, or by any combination thereof. The Repurchase Price shall be paid without interest within the term of the
Repurchase Option as described in Section 8.2. 
 8.5 Right of Termination Unaffected. Nothing in this Exercise Agreement
shall be construed to limit or otherwise affect in any manner whatsoever the right or power of the Company (or any Parent or Subsidiary of the Company) to terminate Purchaser’s employment or other relationship with Company (or the Parent or
Subsidiary of the Company) at any time, for any reason or no reason, with or without Cause. 
 9.
Company’s Right of First Refusal. Unvested Shares may not be sold or otherwise transferred by Purchaser without the Company’s prior written consent. Before any Vested Shares held by Purchaser
or any transferee of such Vested Shares (either sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including, without limitation, a transfer by gift or operation of law), the Company and/or
its assignee(s) will have a right of first refusal to purchase the Vested Shares to be sold or transferred (the “Offered Shares”) on the terms and conditions set forth in this Section (the “Right of First
Refusal”). 

  
 4 

 9.1 Notice of Proposed Transfer. The Holder of the Offered Shares will deliver
to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer the Offered Shares; (ii) the name and address of each proposed purchaser or other transferee (the
“Proposed Transferee”); (iii) the number of Offered Shares to be transferred to each Proposed Transferee; (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Offered Shares (the
“Offered Price”); and (v) that the Holder acknowledges this Notice is an offer to sell the Offered Shares to the Company and/or its assignee(s) pursuant to the Company’s Right of First Refusal at the Offered Price as provided for
in this Exercise Agreement. 
 9.2 Exercise of Right of First Refusal. At any time within thirty (30) days after the date
of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all (or, with the consent of the Holder, less than all) the Offered Shares proposed to be transferred to any one or more of the Proposed
Transferees named in the Notice, at the purchase price, determined as specified below. 
 9.3 Purchase Price. The purchase
price for the Offered Shares purchased under this Section will be the Offered Price, provided that if the Offered Price consists of no legal consideration (as, for example, in the case of a transfer by gift) the purchase price will be the fair
market value of the Offered Shares as determined in good faith by the Company’s Board of Directors. If the Offered Price includes consideration other than cash, then the value of the non-cash
consideration, as determined in good faith by the Company’s Board of Directors, will conclusively be deemed to be the cash equivalent value of such non-cash consideration. 

9.4 Payment. Payment of the purchase price for the Offered Shares will be payable, at the option of the Company and/or its
assignee(s) (as applicable), by check or by cancellation of all or a portion of any outstanding purchase money indebtedness owed by the Holder to the Company (or to such assignee, in the case of a purchase of Offered Shares by such assignee) or by
any combination thereof. The purchase price will be paid without interest within sixty (60) days after the Company’s receipt of the Notice, or, at the option of the Company and/or its assignee(s), in the manner and at the time(s) set forth
in the Notice. 
 9.5 Holder’s Right to Transfer. If all of the Offered 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 Offered Shares to each Proposed Transferee at the Offered Price or at a higher
price, provided that (i) such sale or other transfer is consummated within one hundred twenty (120) days after the date of the Notice, (ii) any such sale or other transfer is effected in compliance with all applicable
securities laws, and (iii) each Proposed Transferee agrees in writing that the provisions of this Section will continue to apply to the Offered Shares in the hands of such Proposed Transferee. If the Offered Shares described in the Notice are
not transferred to each Proposed Transferee within such one hundred twenty (120) day period, then a new Notice must be given to the Company pursuant to which the Company will again be offered the Right of First Refusal before any Shares held by
the Holder may be sold or otherwise transferred. 
 9.6 Exempt Transfers. Notwithstanding anything to the contrary in this
Section, the following transfers of Vested Shares will be exempt from the Right of First Refusal: (i) the transfer of any or all of the Vested Shares during Purchaser’s lifetime by gift or on Purchaser’s death by will or intestacy to
Purchaser’s “Immediate Family” (as defined below) or to a trust for the benefit of Purchaser or Purchaser’s Immediate Family, provided that each transferee or other recipient agrees in a writing satisfactory to the Company that
the provisions of this Section will continue to apply to the transferred 

  
 5 

 
Vested Shares in the hands of such transferee or other recipient; (ii) any transfer of Vested Shares made pursuant to a statutory merger or statutory consolidation of the Company with or
into another corporation or corporations (except that the Right of First Refusal will continue to apply thereafter to such Vested Shares, in which case the surviving corporation of such merger or consolidation shall succeed to the rights of the
Company under this Section unless the agreement of merger or consolidation expressly otherwise provides); or (iii) any transfer of Vested Shares pursuant to the winding up and dissolution of the Company. As used herein, the term “Immediate
Family” will mean “family member” as that term is defined in 17 C.F.R. 230.701 (as of the Effective Date the term includes, but is not limited to: Purchaser’s spouse, father, mother, brother or sister, child, adopted child,
grandchild or adopted grandchild). 
 9.7 Termination of Right of First Refusal. The Right of First Refusal will terminate as
to all Shares (i) on the effective date of the first sale of Common Stock of the Company to the general public pursuant to a registration statement filed with and declared effective by the SEC under the 1933 Act (other than a registration
statement relating solely to the issuance of Common Stock pursuant to a business combination or an employee incentive or benefit plan) or (ii) on any transfer or conversion of Shares made pursuant to a statutory merger or statutory
consolidation of the Company with or into another corporation or corporations if the common stock of the surviving corporation or any direct or indirect parent corporation thereof is registered under the Securities Exchange Act of 1934, as amended.

 9.8 Encumbrances on Vested Shares. Purchaser may grant a lien or security interest in, or pledge, hypothecate or encumber
Vested Shares only if each party to whom such lien or security interest is granted, or to whom such pledge, hypothecation or other encumbrance is made, agrees in a writing satisfactory to the Company that: (i) such lien, security interest,
pledge, hypothecation or encumbrance will not apply to such Vested Shares after they are acquired by the Company and/or its assignees under this Section; and (ii) the provisions of this Section will continue to apply to such Vested Shares in
the hands of such party and any transferee of such party. Purchaser may not grant a lien or security interest in, or pledge, hypothecate or encumber, any Unvested Shares. 

10. Rights as a Stockholder. Subject to the terms and conditions of this Exercise Agreement, Purchaser will have
all of the rights of a stockholder of the Company with respect to the Shares from and after the date that Shares are issued to Purchaser until such time as Purchaser disposes of the Shares or the Company and/or its assignee(s) exercise(s) the
Repurchase Option or Right of First Refusal. Upon an exercise of the Repurchase Option or Right of First Refusal, Purchaser will have no further rights as a holder of the Shares so purchased upon such exercise, other than the right to receive
payment for the Shares so purchased in accordance with the provisions of this Exercise Agreement, and Purchaser will promptly surrender the stock certificate(s) evidencing the Shares so purchased to the Company for transfer or cancellation. 

11. Escrow. As security for Purchaser’s faithful performance of this Exercise Agreement, Purchaser agrees,
immediately upon receipt of the stock certificate(s) evidencing the Shares, to deliver such certificate(s), together with the Stock Powers executed by Purchaser and by Purchaser’s spouse, if any (with the date and number of Shares left blank),
to the Secretary of the Company or other designee of the Company (the “Escrow Holder”), who is hereby appointed to hold such certificate(s) and Stock Powers in escrow and to take all such actions and to effectuate all such
transfers and/or releases of such Shares as are in accordance with the terms of this Exercise Agreement. Purchaser and the Company agree that Escrow Holder will not be liable to any party to this Exercise Agreement (or to any other party) for any
actions or omissions unless Escrow Holder is grossly negligent or intentionally fraudulent in carrying out the duties of Escrow Holder under this Exercise Agreement. Escrow Holder may rely upon any letter, notice or other document executed with any
signature purported to be genuine and may rely on the advice of counsel and obey any order of any court with respect to the transactions contemplated by this Exercise Agreement. The Shares will be released from escrow upon termination of the
Repurchase Option and Right of First Refusal.

 12. Restrictive Legends and Stop-Transfer Orders. 

12.1 Legends. Purchaser understands and agrees that the Company will place the legends set forth below or similar legends on any
stock certificate(s) evidencing the Shares, together with any other legends that may be required by state or U.S. Federal securities laws, the Company’s Certificate of Incorporation or Bylaws, any other agreement between Purchaser and the
Company or any agreement between Purchaser and any third party: 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED
UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE
ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON PUBLIC RESALE AND TRANSFER, INCLUDING THE
REPURCHASE AND RIGHT OF FIRST REFUSAL OPTIONS HELD BY THE ISSUER AND/OR ITS ASSIGNEE(S) AS SET FORTH IN A STOCK OPTION EXERCISE 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 PUBLIC SALE AND TRANSFER RESTRICTIONS INCLUDING THE REPURCHASE AND RIGHT OF FIRST REFUSAL OPTIONS ARE BINDING ON TRANSFEREES OF THESE SHARES. 

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A 180 DAY MARKET STANDOFF RESTRICTION AS SET FORTH IN A CERTAIN 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. AS A RESULT OF SUCH AGREEMENT, THESE SHARES MAY NOT BE TRADED PRIOR TO 180 DAYS AFTER THE EFFECTIVE DATE OF ANY PUBLIC
OFFERING OF THE COMMON STOCK OF THE ISSUER HEREOF. SUCH RESTRICTION IS BINDING ON TRANSFEREES OF THESE SHARES. 
 12.2
Stop-Transfer Instructions. Purchaser agrees that, to ensure compliance with the restrictions imposed by this Exercise Agreement, the Company may issue appropriate “stop-transfer” instructions to its transfer agent, if any, and
if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 
 12.3
Refusal to Transfer. The Company will 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 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 have been so transferred.

 13. Tax Consequences. PURCHASER UNDERSTANDS THAT PURCHASER MAY
SUFFER ADVERSE TAX CONSEQUENCES AS A RESULT OF PURCHASER’S PURCHASE OR DISPOSITION OF THE SHARES. PURCHASER REPRESENTS: (i) THAT PURCHASER HAS CONSULTED WITH ANY TAX ADVISER THAT PURCHASER DEEMS ADVISABLE IN CONNECTION WITH THE PURCHASE OR
DISPOSITION OF THE SHARES AND (ii) THAT PURCHASER IS NOT RELYING ON THE COMPANY FOR ANY TAX ADVICE. IN PARTICULAR, IF UNVESTED SHARES ARE SUBJECT TO REPURCHASE BY THE COMPANY, PURCHASER REPRESENTS THAT PURCHASER HAS CONSULTED WITH
PURCHASER’S OWN TAX ADVISER CONCERNING THE ADVISABILITY OF FILING AN 83(b) ELECTION WITH THE INTERNAL REVENUE SERVICE WHICH MUST BE FILED WITHIN THIRTY (30) DAYS OF THE PURCHASE OF SHARES TO BE EFFECTIVE. Set forth below is a brief summary
as of the date the Plan was adopted by the Board of some of the U.S. federal tax consequences of exercise of the Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
PURCHASER SHOULD CONSULT HIS OR HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES. 
 13.1 Exercise of
Incentive Stock Option. If the Option qualifies as an ISO, there will be no regular U.S. federal income tax liability upon the exercise of the Option, although the excess, if any, of the Fair Market Value of the Shares on the date of exercise
over the Exercise Price will be treated as a tax preference item for U.S. Federal alternative minimum tax purposes and may subject Purchaser to the alternative minimum tax in the year of exercise. 

13.2 Exercise of Nonqualified Stock Option. If the Option does not qualify as an ISO, there may be a regular U.S. federal income
tax liability upon the exercise of the Option. Purchaser will be treated as having received compensation income (taxable at ordinary income tax rates) equal to the excess, if any, of the Fair Market Value of the Shares on the date of exercise over
the Exercise Price. If Purchaser is or was an employee of the Company, the Company may be required to withhold from Purchaser’s compensation or collect from Purchaser and pay to the applicable taxing authorities an amount equal to a percentage
of this compensation income at the time of exercise. 
 13.3 Disposition of Shares. The following tax consequences may apply
upon disposition of the Shares. 
 (a) Incentive Stock Options. If the Shares are held for more than twelve (12) months after
the date of purchase of the Shares pursuant to the exercise of an ISO and are disposed of more than two (2) years after the Date of Grant, any gain realized on disposition of the Shares will be treated as long term capital gain for U.S. federal
income tax purposes. If Vested Shares purchased under an ISO are disposed of within the applicable one (1) year or two (2) year period, any gain realized on such disposition will be treated as compensation income (taxable at ordinary
income rates in the year of the disposition) to the extent of the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price. To the extent the Shares were exercised prior to vesting coincident with the
filing of an 83(b) Election, the amount taxed because of a disqualifying disposition will be based upon the excess, if any, of the fair market value on the date of vesting over the exercise price. 

(b) Nonqualified Stock Options. If the Shares are held for more than twelve (12) months after the date of the transfer of the
Shares pursuant to the exercise of an NQSO, any gain realized on disposition of the Shares will be treated as long term capital gain. 
 (c)
Withholding. The Company may be required to withhold from the Purchaser’s compensation or collect from the Purchaser and pay to the applicable taxing authorities an amount equal to a percentage of this compensation income. 

  
 8 

 13.4 Section 83(b) Election for Unvested
Shares. With respect to Unvested Shares, which are subject to the Repurchase Option, unless an election is filed by the Purchaser with the Internal Revenue Service (and, if necessary, the proper state taxing authorities), within 30
days of the purchase of the Unvested Shares, electing pursuant to Section 83(b) of the Code (and similar state tax provisions, if applicable) to be taxed currently on any difference between the Exercise Price of the Unvested Shares and
their Fair Market Value on the date of purchase, there may be a recognition of taxable income (including, where applicable, alternative minimum taxable income) to the Purchaser, measured by the excess, if any, of the Fair Market Value of the
Unvested Shares at the time they cease to be Unvested Shares, over the Exercise Price of the Unvested Shares. 
 14. Compliance
with Laws and Regulations. The issuance and transfer of the Shares will be subject to and conditioned upon compliance by the Company and Purchaser with all applicable state and U.S. federal laws and regulations and with all applicable
requirements of any stock exchange or automated quotation system on which the Company’s Common Stock may be listed or quoted at the time of such issuance or transfer. 

15. Successors and Assigns. The Company may assign any of its rights and obligations under this Exercise
Agreement, including its rights to purchase Shares under the Repurchase Option and Right of First Refusal. No other party to this Exercise Agreement may assign, whether voluntarily or by operation of law, any of its rights and obligations under this
Exercise Agreement, except with the prior written consent of the Company. This Exercise Agreement shall be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth,
this Exercise Agreement will be binding upon Purchaser and Purchaser’s heirs, executors, administrators, legal representatives, successors and assigns. 

16. Governing Law. This Exercise Agreement shall be governed by and construed in accordance with the laws of the
State of California, without giving effect to that body of laws pertaining to conflict of laws. 
 17. Notices.
Any and all notices required or permitted to be given to a party pursuant to the provisions of this Exercise Agreement will be in writing and will be effective and deemed to provide such party sufficient notice under this Exercise Agreement on the
earliest of the following: (i) at the time of personal delivery, if delivery is in person; (ii) one (1) business day after deposit with an express overnight courier for United States deliveries, or two (2) business days after
such deposit for deliveries outside of the United States, with proof of delivery from the courier requested; or (iii) three (3) business days after deposit in the United States mail by certified mail (return receipt requested) for United States
deliveries. 
 18. Further Assurances. The parties agree to execute such further documents and instruments and
to take such further actions as may be reasonably necessary to carry out the purposes and intent of this Exercise Agreement. 
 19.
Titles and Headings. The titles, captions and headings of this Exercise Agreement are included for ease of reference only and will be disregarded in interpreting or construing this Exercise Agreement. Unless otherwise
specifically stated, all references herein to “sections” and “exhibits” will mean “sections” and “exhibits” to this Exercise Agreement. 

20. Entire Agreement. The Plan, the Stock Option Agreement, the Notice (as defined in the Notice of Exercise), the
Exercise Notice and this Exercise Agreement, together with all exhibits thereto, constitute the entire agreement and understanding of the parties with respect to the subject matter of this Exercise Agreement, and supersede all prior understandings
and agreements, whether oral or written, between or among the parties hereto with respect to the specific subject matter hereof. 

  
 9 

 21. Severability. If any provision of this Exercise Agreement is
determined by any court or arbitrator of competent jurisdiction to be invalid, illegal or unenforceable in any respect, such provision will be enforced to the maximum extent possible given the intent of the parties hereto. If such clause or
provision cannot be so enforced, such provision shall be stricken from this Exercise Agreement and the remainder of this Exercise Agreement shall be enforced as if such invalid, illegal or unenforceable clause or provision had (to the extent not
enforceable) never been contained in this Exercise Agreement. Notwithstanding the forgoing, if the value of this Exercise Agreement based upon the substantial benefit of the bargain for any party is materially impaired, which determination as made
by the presiding court or arbitrator of competent jurisdiction shall be binding, then both parties agree to substitute such provision(s) through good faith negotiations.

 Exhibit 10.3 

BILL.COM HOLDINGS, INC. 

(FORMERLY KNOWN AS BDC PAYMENTS HOLDINGS, INC.)

 2016 EQUITY INCENTIVE PLAN 

As Adopted on February 22, 2016 

As amended on July 28, 2016, June 21, 2017, February 13, 2018, November 26, 2018 

December 20, 2018 and July 22, 2019 

1. PURPOSE. The purpose of this Plan is to provide incentives to attract, retain and motivate eligible persons
whose present and potential contributions are important to the success of the Company, its Parent and Subsidiaries by offering eligible persons an opportunity to participate in the Company’s future performance through the grant of Awards
covering Shares. Capitalized terms not defined in the text are defined in Section 14 hereof. Although this Plan is intended to be a written compensatory benefit plan within the meaning of Rule 701, grants may be made pursuant to this Plan
that do not qualify for exemption under Rule 701 or Section 25102(o). Any requirement of this Plan that is required in law only because of Section 25102(o) need not apply if the Committee so provides. 

2. SHARES SUBJECT TO THE PLAN. 

2.1 Number of Shares Available. Subject to Sections 2.2 and 11 hereof, the total number of Shares reserved and
available for grant and issuance pursuant to this Plan will be the sum of: (a) 20,298,730 shares; plus (b) shares that are subject to issuance under the Company’s 2006 Equity Incentive Plan (the “Prior Plan”) but
cease to be subject to an award for any reason other than exercise of an Option after the date hereof; plus (c) shares that were issued under the Prior Plan which are repurchased by the Company or which are forfeited or used to pay withholding
obligations or pay the exercise price of an Option. Subject to Sections 2.2 and 11 hereof, Shares subject to Awards that are cancelled, forfeited, settled in cash, used to pay withholding obligations or pay the exercise price of an Option or
that expire by their terms at any time will again be available for grant and issuance in connection with other Awards. In the event that Shares previously issued under the Plan are reacquired by the Company pursuant to a forfeiture provision, right
of first refusal, or repurchase by the Company, such Shares shall be added to the number of Shares then available for issuance under the Plan. At all times the Company will reserve and keep available a sufficient number of Shares as will be required
to satisfy the requirements of all Awards granted and outstanding under this Plan. 
 In no event shall the total number of Shares issued (counting each
reissuance of a Share that was previously issued and then forfeited or repurchased by the Company as a separate issuance) under the Plan upon exercise of ISOs exceed Fifty Three Million One Hundred Thirty One Thousand One Hundred Thirty Eight
(53,131,138) Shares (adjusted in proportion to any adjustments under Section 2.2 hereof) over the term of the Plan (the “ISO Limit”). Subject to Sections 2.2 and 11 hereof, in the event that the number of Shares reserved
for issuance under the Plan is increased, the ISO Limit shall be automatically increased by such number of Shares such that the ISO Limit equals (a) two (2) multiplied by (b) the number of Shares reserved for issuance under the Plan. 

2.2 Adjustment of Shares. In the event that the Company’s Common Stock is changed by a stock dividend,
recapitalization, stock split, reverse stock split, subdivision, combination, reclassification, spin-off or other change in the capital structure of the Company affecting Shares without consideration, then in
order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan (a) the number and class of Shares reserved for issuance under this Plan, (b) the Exercise Prices of and number
and class of Shares subject to outstanding Options 

  
 1 

 
and SARs, and (c) the Purchase Prices of and/or number and class of Shares subject to other outstanding Awards will (to the extent appropriate) be proportionately adjusted, subject to any
required action by the Board or the stockholders of the Company and compliance with applicable securities laws; provided, however, that fractions of a Share will not be issued but will either be paid in cash at the Fair
Market Value of such fraction of a Share or will be rounded down to the nearest whole Share, as determined by the Committee. 
 3.
PLAN FOR BENEFIT OF SERVICE PROVIDERS. 
 3.1 Eligibility. The Committee will have the authority to
select persons to receive Awards. ISOs (as defined in Section 4 hereof) may be granted only to employees (including officers and directors who are also employees) of the Company or of a Parent or Subsidiary of the Company. NQSOs (as defined in
Section 4 hereof) and all other types of Awards may be granted to employees, officers, directors and consultants of the Company or any Parent or Subsidiary of the Company; provided any such consultant renders bona fide services
not in connection with the offer and sale of securities in a capital-raising transaction when Rule 701 is to apply to the Award granted for such services. A person may be granted more than one Award under this Plan. 

3.2 No Obligation to Employ. Nothing in this Plan or any Award granted under this Plan will confer or be deemed to confer
on any Participant any right to continue in the employ of, or to continue any other relationship with, the Company or any Parent or Subsidiary or limit in any way the right of the Company or any Parent or Subsidiary to terminate Participant’s
employment or other relationship at any time, with or without Cause. 
 4. OPTIONS. The Committee may grant
Options to eligible persons described in Section 3 hereof and will determine whether such Options will be Incentive Stock Options within the meaning of the Code (“ISOs”) or Nonqualified Stock Options
(“NQSOs”), the number of Shares subject to the Option, the Exercise Price of the Option, the period during which the Option may be exercised, and all other terms and conditions of the Option, subject to the following terms
and conditions. 
 4.1 Form of Option Grant. Each Option granted under this Plan will be evidenced by an Award Agreement
which will expressly identify the Option as an ISO or an NQSO (“Stock Option Agreement”), and will be in such form and contain such provisions (which need not be the same for each Participant) as the Committee may from time
to time approve, and which will comply with and be subject to the terms and conditions of this Plan. 
 4.2 Date of
Grant. The date of grant of an Option will be the date on which the Committee makes the determination to grant such Option, unless a later date is otherwise specified by the Committee. The Stock Option Agreement and a copy of this Plan will
be delivered to the Participant within a reasonable time after the granting of the Option. 
 4.3 Exercise Period.
Options may be exercisable within the time or upon the events determined by the Committee in the Award Agreement and may be awarded as immediately exercisable but subject to repurchase pursuant to Section 10 hereof or may be exercisable within
the times or upon the events determined by the Committee as set forth in the Stock Option Agreement governing such Option; provided, however, that (a) no Option will be exercisable after the expiration of ten
(10) years from the date the Option is granted; and (b) no ISO granted to a person who directly or by attribution owns more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or of any Parent
or Subsidiary (“Ten Percent Stockholder”) will be exercisable after the expiration of five (5) years from the date the ISO is granted; but in no event shall an Option granted to an employee who is a non-exempt employee for purposes of overtime pay under the U.S. Fair Labor Standards Act of 1938 be 

  
 2 

 
exercisable earlier than six (6) months after its date of grant. The Committee also may provide for Options to become exercisable at one time or from time to time, periodically or otherwise,
in such number of Shares or percentage of Shares as the Committee determines. In addition, if an Option is determined to otherwise be subject to Section 409A of the Code, such Option shall be exercisable for the Shares subject to such Option no
later than the end of the applicable short-term deferral period determined under Section 409A of the Code by the Committee, except as otherwise determined by the Committee. 

4.4 Exercise Price. The Exercise Price of an Option will be determined by the Committee when the Option is granted and
shall not be less than the Fair Market Value per Share on the date of grant unless expressly determined in writing by the Committee on the Option’s date of grant; provided that the Exercise Price of an ISO granted to a Ten Percent
Stockholder will not be less than one hundred ten percent (110%) of the Fair Market Value of the Shares on the date of grant. Payment for the Shares purchased must be made in accordance with Section 8 hereof. 

4.5 Method of Exercise. Options may be exercised only by delivery to the Company of a written stock option exercise
agreement (accepted via written, electronic or other means) (the “Exercise Agreement”) in a form approved by the Committee (which need not be the same for each Participant). The Exercise Agreement will state (a) the
number of Shares being purchased, (b) the restrictions imposed on the Shares purchased under such Exercise Agreement, if any, and (c) such representations and agreements regarding Participant’s investment intent and access to
information and other matters, if any, as may be required or desirable by the Company to comply with applicable securities laws. Each Participant’s Exercise Agreement may be modified by (i) agreement of Participant and the Company or
(ii) substitution by the Company, upon becoming a public company, in order to add the payment terms set forth in Section 8.1 that apply to a public company and such other terms as shall be necessary or advisable in order to exercise a
public company option. Upon exercise of an Option, Participant shall execute and deliver to the Company the Exercise Agreement then in effect, together with payment in full of the Exercise Price for the number of Shares being purchased and payment
of any applicable taxes. 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 2.2 of the Plan. Exercising an Option in any manner will
decrease 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. 

4.6 Termination. Subject to earlier termination pursuant to Sections 11 and 13 hereof and notwithstanding the
exercise periods set forth in the Stock Option Agreement, exercise of an Option will always be subject to the following terms and conditions. 

4.6.1 Other than Death or Disability or for Cause. If the Participant is Terminated for any reason other than death, Disability or for
Cause, then the Participant may exercise such Participant’s Options only to the extent that such Options are exercisable as to Vested Shares upon the Termination Date or as otherwise determined by the Committee. Such Options must be exercised
by the Participant, if at all, as to all or some of the Vested Shares calculated as of the Termination Date or such other date determined by the Committee, within three (3) months after the Termination Date (or within such shorter time period,
not less than thirty (30) days, or within such longer time period after the Termination Date as may be determined by the Committee, with any exercise beyond three (3) months after the date Participant ceases to be an employee deemed to be
an NQSO) but in any event, no later than the expiration date of the Options. 
 4.6.2 Death or Disability. If the Participant is
Terminated because of Participant’s death or Disability (or the Participant dies within three (3) months after a Termination other than for Cause), then Participant’s Options may be exercised only to the extent that such Options are
exercisable as to Vested Shares by Participant on the Termination Date or as otherwise determined by the 

  
 3 

 
Committee. Such options must be exercised by Participant (or Participant’s legal representative or authorized assignee), if at all, as to all or some of the Vested Shares calculated as of
the Termination Date or such other date determined by the Committee, within twelve (12) months after the Termination Date (or within such shorter time period, not less than six (6) months, or within such longer time period, after the
Termination Date as may be determined by the Committee, with any exercise beyond (a) three (3) months after the date Participant ceases to be an employee when the Termination is for any reason other than the Participant’s death or
disability, within the meaning of Section 22(e)(3) of the Code, or (b) twelve (12) months after the date Participant ceases to be an employee when the Termination is for Participant’s disability, within the meaning of
Section 22(e)(3) of the Code, deemed to be an NQSO) but in any event no later than the expiration date of the Options. 
 4.6.3 For
Cause. If the Participant is Terminated for Cause, the Participant may exercise such Participant’s Options, but not to an extent greater than such Options are exercisable as to Vested Shares upon the Termination Date and Participant’s
Options shall expire on such Participant’s Termination Date, or at such later time and on such conditions as are determined by the Committee. 

4.7 Limitations on Exercise. The Committee may specify a reasonable minimum number of Shares that may be purchased on any
exercise of an Option, provided that such minimum number will not prevent Participant from exercising the Option for the full number of Shares for which it is then exercisable. 

4.8 Limitations on ISOs. The aggregate Fair Market Value (determined as of the date of grant) of Shares with respect to
which ISOs are exercisable for the first time by a Participant during any calendar year (under this Plan or under any other incentive stock option plan of the Company or any Parent or Subsidiary of the Company) will not exceed One Hundred Thousand
Dollars ($100,000). If the Fair Market Value of Shares on the date of grant with respect to which ISOs are exercisable for the first time by a Participant during any calendar year exceeds One Hundred Thousand Dollars ($100,000), then the Options for
the first One Hundred Thousand Dollars ($100,000) worth of Shares to become exercisable in such calendar year will be ISOs and the Options for the amount in excess of One Hundred Thousand Dollars ($100,000) that become exercisable in that calendar
year will be NQSOs. In the event that the Code or the regulations promulgated thereunder are amended after the Effective Date (as defined in Section 13.1 hereof) to provide for a different limit on the Fair Market Value of Shares permitted to
be subject to ISOs, then such different limit will be automatically incorporated herein and will apply to any Options granted after the effective date of such amendment. 

4.9 Modification, Extension or Renewal. The Committee may modify, extend or renew outstanding Options and authorize the
grant of new Options in substitution therefor, provided that any such action may not, without the written consent of a Participant, impair any of such Participant’s rights under any Option previously granted. Any outstanding ISO
that is modified, extended, renewed or otherwise altered will be treated in accordance with Section 424(h) of the Code. Subject to Section 4.10 hereof, the Committee may reduce the Exercise Price of outstanding Options without the consent
of Participants by a written notice to them; provided, however, that the Exercise Price may not be reduced below the minimum Exercise Price that would be permitted under Section 4.4 hereof for Options granted on the
date the action is taken to reduce the Exercise Price. 
 4.10 No Disqualification. Notwithstanding any other provision
in this Plan, no term of this Plan relating to ISOs will be interpreted, amended or altered, nor will any discretion or authority granted under this Plan be exercised, so as to disqualify this Plan under Section 422 of the Code or, without the
consent of the Participant, to disqualify any Participant’s ISO under Section 422 of the Code.

 5. RESTRICTED STOCK. A Restricted Stock Award is an offer by the
Company to sell to an eligible person Shares that are subject to certain specified restrictions. The Committee will determine to whom an offer will be made, the number of Shares the person may purchase, the Purchase Price, the restrictions to which
the Shares will be subject, and all other terms and conditions of the Restricted Stock Award, subject to the following terms and conditions. 

5.1 Form of Restricted Stock Award. All purchases under a Restricted Stock Award made pursuant to this Plan will be
evidenced by an Award Agreement (“Restricted Stock Purchase Agreement”) that will be in such form (which need not be the same for each Participant) as the Committee will from time to time approve, and will comply with and be
subject to the terms and conditions of this Plan. The Restricted Stock Award will be accepted by the Participant’s execution and delivery of the Restricted Stock Purchase Agreement (accepted via written, electronic or other means) and full
payment for the Shares to the Company within thirty (30) days from the date the Restricted Stock Purchase Agreement is delivered to the person. If such person does not execute and deliver the Restricted Stock Purchase Agreement along with full
payment for the Shares to the Company within such thirty (30) days, then the offer will terminate, unless otherwise determined by the Committee. 

5.2 Purchase Price. The Purchase Price of Shares sold pursuant to a Restricted Stock Award will be determined by the
Committee on the date the Restricted Stock Award is granted or at the time the purchase is consummated. Payment of the Purchase Price must be made in accordance with Section 8 hereof. 

5.3 Dividends and Other Distributions. Participants holding Restricted Stock will be entitled to receive all dividends and
other distributions paid with respect to such Shares, unless the Committee provides otherwise at the time the Award is granted. If any such dividends or distributions are paid in Shares, the Shares will be subject to the same restrictions on
transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid. 
 5.4
Restrictions. Restricted Stock Awards may be subject to the restrictions set forth in Sections 9 and 10 hereof or, with respect to a Restricted Stock Award to which Section 25102(o) is to apply, such other restrictions
not inconsistent with Section 25102(o). 
 6. RESTRICTED STOCK UNITS. 

6.1 Awards of Restricted Stock Units. A Restricted Stock Unit (“RSU”) is an Award covering a
number of Shares that may be settled in cash, or by issuance of those Shares at a date in the future, or by a combination of cash and Shares. No Purchase Price shall apply to an RSU settled in Shares. All grants of Restricted Stock Units will be
evidenced by an Award Agreement that will be in such form (which need not be the same for each Participant) as the Committee will from time to time approve, and will comply with and be subject to the terms and conditions of this Plan. No RSU will
have a term longer than ten (10) years from the date the RSU is granted. 
 6.2 Form and Timing of Settlement. To
the extent permissible under applicable law, the Committee may permit a Participant to defer payment (including settlement) under a RSU to a date or dates after the RSU is earned, provided that the terms of the RSU and any deferral
satisfy the requirements of Section 409A of the Code (or any successor) and any regulations or rulings promulgated thereunder, to the extent the Participant is subject to Section 409A of the Code. Payment may be made in the form of cash or
whole Shares or a combination thereof, all as the Committee determines. 

  
 5 

 6.3 Dividend Equivalent Payments. The Board may permit
Participants holding RSUs to receive dividend equivalent payments on outstanding RSUs if and when dividends are paid to stockholders on Shares. In the discretion of the Board, such dividend equivalent payments may be paid in cash or Shares and
they may either be paid at the same time as dividend payments are made to stockholders or delayed until when Shares are issued pursuant to the RSU grants and may be subject to the same vesting requirements as the RSUs. If the Board permits
dividend equivalent payments to be made on RSUs, the terms and conditions for such payments will be set forth in the Award Agreement. 

7. STOCK APPRECIATION RIGHTS. 

7.1 Awards of SARs. Stock Appreciation Rights (“SARs”) may be settled in cash, or Shares (which
may consist of Restricted Stock or RSUs), having a value equal to the value determined by multiplying the difference between the Fair Market Value on the date of exercise over the Exercise Price and the number of Shares with respect to which the SAR
is being settled. All grants of SARs made pursuant to this Plan will be evidenced by an Award Agreement that will be in such form (which need not be the same for each Participant) as the Committee will from time to time approve, and will comply with
and be subject to the terms and conditions of this Plan. 
 7.2 Exercise Period and Expiration Date. A SAR will be
exercisable within the times or upon the occurrence of events determined by the Committee and set forth in the Award Agreement governing such SAR. The Award Agreement shall set forth the Expiration Date; provided that no SAR will be
exercisable after the expiration of ten years from the date the SAR is granted. 
 7.3 Exercise Price. The Committee
will determine the Exercise Price of the SAR when the SAR is granted, and which may not be less than the Fair Market Value on the date of grant and may be settled in cash or in Shares. 

7.4 Termination. Subject to earlier termination pursuant to Sections 11 and 13 hereof and notwithstanding the
exercise periods set forth in the Award Agreement, exercise of SARs will always be subject to the following terms and conditions. 
 7.4.1
Other than Death or Disability or for Cause. If the Participant is Terminated for any reason other than death, Disability or for Cause, then the Participant may exercise such Participant’s SARs only to the extent that such SARs are
exercisable as to Vested Shares upon the Termination Date or as otherwise determined by the Committee. SARs must be exercised by the Participant, if at all, as to all or some of the Vested Shares calculated as of the Termination Date or such other
date determined by the Committee, within three (3) months after the Termination Date (or within such shorter time period, not less than thirty (30) days, or within such longer time period after the Termination Date as may be determined by
the Committee) but in any event, no later than the expiration date of the SARs. 
 7.4.2 Death or Disability. If the Participant is
Terminated because of Participant’s death or Disability (or the Participant dies within three (3) months after a Termination other than for Cause), then Participant’s SARs may be exercised only to the extent that such SARs are
exercisable as to Vested Shares by Participant on the Termination Date or as otherwise determined by the Committee. Such SARs must be exercised by Participant (or Participant’s legal representative or authorized assignee), if at all, as to all
or some of the Vested Shares calculated as of the Termination Date or such other date determined by the Committee, within twelve (12) months after the Termination Date (or within such shorter time period, not less than six (6) months, or
within such longer time period after the Termination Date as may be determined by the Committee) but in any event no later than the expiration date of the SARs. 

  
 6 

 7.4.3 For Cause. If the Participant is terminated for Cause, the Participant may
exercise such Participant’s SARs, but not to an extent greater than such SARs are exercisable as to Vested Shares upon the Termination Date and Participant’s SARs shall expire on such Participant’s Termination Date, or at such later
time and on such conditions as are determined by the Committee. 
 8. PAYMENT FOR PURCHASES AND EXERCISES. 

8.1 Payment in General. Payment for Shares acquired pursuant to this Plan may be made in cash equivalents (including (by
check or Automated Clearing House (“ACH”) transfer) or, where expressly approved for the Participant by the Committee and where permitted by law: 

(a) by cancellation of indebtedness of the Company owed to the Participant; 

(b) by surrender of shares of the Company that are clear of all liens, claims, encumbrances or security interests and: (i) for which the
Company has received “full payment of the purchase price” within the meaning of SEC Rule 144 (and, if such shares were purchased from the Company by use of a promissory note, such note has been fully paid with respect to such shares)
or (ii) that were obtained by Participant in the public market; 
 (c) by tender of a full recourse promissory note having such terms
as may be approved by the Committee and bearing interest at a rate sufficient to avoid imputation of income under Sections 483 and 1274 of the Code; provided, however, that Participants who are not employees or
directors of the Company will not be entitled to purchase Shares with a promissory note unless the note is adequately secured by collateral other than the Shares; provided, further, that the portion of the Exercise Price
or Purchase Price, as the case may be, equal to the par value (if any) of the Shares must be paid in cash or other legal consideration permitted by the laws under which the Company is then incorporated or organized; 

(d) by waiver of compensation due or accrued to the Participant from the Company for services rendered; 

(e) by participating in a formal cashless exercise program implemented by the Committee in connection with the Plan; 

(f) subject to compliance with applicable law, provided that a public market for the Company’s Common Stock exists, by exercising through
a “same day sale” commitment from the Participant and a broker-dealer whereby the Participant irrevocably elects to exercise the Award and to sell a portion of the Shares so purchased sufficient to pay the total Exercise Price or Purchase
Price, and whereby the broker-dealer irrevocably commits upon receipt of such Shares to forward the total Exercise Price or Purchase Price directly to the Company; or 

(g) by any combination of the foregoing or any other method of payment approved by the Committee. 

For avoidance of uncertainty: ACH transfers that have been received by the Company into its bank account designated for receipt of such transfers under this
Section 8.1 shall be deemed to have been received for all purposes under this Plan as of the date on which such transfers were initiated from the transferor’s account and made irrevocable by the transferor. 

  
 7 

 8.2 Withholding Taxes. 

8.2.1 Withholding Generally. Whenever Shares are to be issued in satisfaction of Awards granted under this Plan, the Company may
require the Participant to remit to the Company an amount sufficient to satisfy the maximum tax withholding requirements as to income tax, social insurance, payroll tax, fringe benefits tax, payment on account and other tax-related obligations (collectively, “Tax-Related Obligations”) prior to the delivery of any certificate or certificates for such Shares. Whenever,
under this Plan, payments in satisfaction of Awards are to be made in cash by the Company, such payment will be net of an amount sufficient to satisfy applicable tax withholding requirements. 

8.2.2 Stock Withholding. When, under applicable tax laws, a Participant incurs tax liability in connection with the exercise or vesting
of any Award that is subject to tax withholding and the Participant is obligated to pay the Company the amount required to be withheld, the Committee may in its sole discretion allow the Participant to satisfy up to the maximum Tax-Related Obligations in the employee’s applicable jurisdictions by electing to have the Company withhold from the Shares to be issued up to the minimum number of Shares having a Fair Market Value on the date
that the amount of tax to be withheld is to be determined that is not more than the minimum amount to be withheld; or to arrange a mandatory “sell to cover” on Participant’s behalf (without further authorization) but in no event will
the Company withhold Shares or “sell to cover” if such withholding would result in adverse accounting consequences to the Company. The maximum Tax-Related Obligations are based on the applicable
rates of the relevant tax authorities (for example, federal, state and local), including the employee’s share of payroll or similar taxes, as provided in the tax law, regulations or the authority’s administrative practices, not to exceed
the highest statutory rate in that jurisdiction. Any elections to have Shares withheld or sold for this purpose will be made in accordance with the requirements established by the Committee for such elections and be in writing in a form acceptable
to the Committee. 
 8.2.3 Elections Under Section 83(i) of the Code. A Participant will not make an election
under Section 83(i) of the Code if the Company determines that the Participant is then ineligible to make such an election under applicable law or without the Company’s prior written consent (which will not be unreasonably withheld or
delayed, but may be conditioned upon the Participant’s entry into additional commitments as determined by the Company). 
 9.
RESTRICTIONS ON AWARDS. 
 9.1 Transferability. Except as permitted by the Committee, Awards granted
under this Plan, and any interest therein, will not be transferable or assignable by Participant, other than by will or by the laws of descent and distribution, and, with respect to NQSOs, by instrument to an inter vivos or testamentary trust in
which the NQSOs are to be passed to beneficiaries upon the death of the trustor (settlor), or by gift to “family member” as that term is defined in Rule 701, and may not be made subject to execution, attachment or similar process. For the
avoidance of doubt, the prohibition against assignment and transfer applies to a stock option and, prior to exercise, the shares to be issued on exercise of a stock option, and pursuant to the foregoing sentence shall be understood to include,
without limitation, a prohibition against any pledge, hypothecation, or other transfer, including any short position, any “put equivalent position” or any “call equivalent position” (in each case, as defined in Rule 16a-1 promulgated under the Exchange Act). Unless an Award is transferred pursuant to the terms of this Section, during the lifetime of the Participant an Award will be exercisable only by the Participant or
Participant’s legal representative and any elections with respect to an Award may be made only by the Participant or Participant’s legal representative. The terms of an Option shall be binding upon the executor, administrator, successors
and assigns of the Participant who is a party thereto. 

  
 8 

 9.2 Securities Law and Other Regulatory Compliance. Although this Plan
is intended to be a written compensatory benefit plan within the meaning of Rule 701 promulgated under the Securities Act, grants may be made pursuant to this Plan that do not qualify for exemption under Rule 701 or Section 25102(o). Any
requirement of this Plan which is required in law only because of Section 25102(o) need not apply with respect to a particular Award to which Section 25102(o) will not apply. An Award will not be effective unless such Award is in
compliance with all applicable federal and state securities laws, rules and regulations of any governmental body, and the requirements of any stock exchange or automated quotation system upon which the Shares may then be listed or quoted, as they
are in effect on the date of grant of the Award and also on the date of exercise or other issuance. Notwithstanding any other provision in this Plan, the Company will have no obligation to issue or deliver certificates for Shares under this Plan
prior to (a) obtaining any approvals from governmental agencies that the Company determines are necessary or advisable, and/or (b) compliance with any exemption, completion of any registration or other qualification of such Shares under
any state or federal law or ruling of any governmental body that the Company determines to be necessary or advisable. The Company will be under no obligation to register the Shares with the SEC or to effect compliance with the exemption,
registration, qualification or listing requirements of any state securities laws, stock exchange or automated quotation system, and the Company will have no liability for any inability or failure so do. 

9.3 Exchange and Buyout of Awards. The Committee may, at any time or from time to time, authorize the Company, with the
consent of the respective Participants, to issue new Awards in exchange for the surrender and cancellation of any or all outstanding Awards. Without prior stockholder approval the Committee may reprice Options or SARs (and where such repricing is a
reduction in the Exercise Price of outstanding Options or SARs, the consent of the affected Participants is not required provided written notice is provided to them). The Committee may at any time buy from a Participant an Award previously granted
with payment in cash, Shares (including Restricted Stock) or other consideration, based on such terms and conditions as the Committee and the Participant may agree. 

10. RESTRICTIONS ON SHARES. 

10.1 Privileges of Stock Ownership. No Participant will have any of the rights of a stockholder with respect to any Shares
until such Shares are issued to the Participant. After Shares are issued to the Participant, the Participant will be a stockholder and have all the rights of a stockholder with respect to such Shares, including the right to vote and receive all
dividends or other distributions made or paid with respect to such Shares; provided, that if such Shares are Restricted Stock, then any new, additional or different securities the Participant may become entitled to receive with respect
to such Shares by virtue of a stock dividend, stock split or any other change in the corporate or capital structure of the Company will be subject to the same restrictions as the Restricted Stock. The Participant will have no right to retain such
stock dividends or stock distributions with respect to Unvested Shares that are repurchased as described in this Section 10. 
 10.2
Rights of First Refusal and Repurchase. At the discretion of the Committee, the Company may reserve to itself and/or its assignee(s) in the Award Agreement (a) a right of first refusal to purchase all Shares that a Participant
(or a subsequent transferee) may propose to transfer to a third party, provided that such right of first refusal terminates upon the Company’s initial public offering of Common Stock pursuant to an effective registration statement
filed under the Securities Act and (b) a right to repurchase Unvested Shares held by a Participant for cash and/or cancellation of purchase money indebtedness owed to the Company by the Participant following such Participant’s Termination
at any time. 

  
 9 

 10.3 Escrow; Pledge of Shares. To enforce any restrictions on a
Participant’s Shares, the Committee may require the Participant to deposit all certificates representing Shares, together with stock powers or other instruments of transfer approved by the Committee, appropriately endorsed in blank, with the
Company or an agent designated by the Company to hold in escrow until such restrictions have lapsed or terminated. The Committee may cause a legend or legends referencing such restrictions to be placed on the certificate. Any Participant who is
permitted to execute a promissory note as partial or full consideration for the purchase of Shares under this Plan will be required to pledge and deposit with the Company all or part of the Shares so purchased as collateral to secure the payment of
Participant’s obligation to the Company under the promissory note; provided, however, that the Committee may require or accept other or additional forms of collateral to secure the payment of such obligation and, in
any event, the Company will have full recourse against the Participant under the promissory note notwithstanding any pledge of the Participant’s Shares or other collateral. In connection with any pledge of the Shares, Participant will be
required to execute and deliver a written pledge agreement in such form as the Committee will from time to time approve. The Shares purchased with the promissory note may be released from the pledge on a pro rata basis as the promissory note is
paid. 
 10.4 Securities Law Restrictions. All certificates for Shares or other securities delivered under this Plan
will be subject to such stock transfer orders, legends and other restrictions as the Committee may deem necessary or advisable, including restrictions under any applicable federal, state or foreign securities law, or any rules, regulations and other
requirements of the SEC or any stock exchange or automated quotation system upon which the Shares may be listed or quoted. 
 11.
CORPORATE TRANSACTIONS. 
 11.1 Acquisitions or Other Combinations. In the event that the Company is
subject to an Acquisition or Other Combination, outstanding Awards acquired under the Plan shall be subject to the agreement evidencing the Acquisition or Other Combination, which need not treat all outstanding Awards in an identical manner. Such
agreement, without the Participant’s consent, shall provide for one or more of the following with respect to all outstanding Awards as of the effective date of such Acquisition or Other Combination: 

(a) The continuation of such outstanding Awards by the Company (if the Company is the successor entity). 

(b) The assumption of outstanding Awards by the successor or acquiring entity (if any) in such Acquisition or Other Combination (or by any of
its Parents, if any), which assumption, will be binding on all Participants; provided that the exercise price and the number and nature of shares issuable upon exercise of any such option or stock appreciation right, or any award that is subject to
Section 409A of the Code, will be adjusted appropriately pursuant to Section 424(a) and Section 409A of the Code. For the purposes of this Section 11, an Award will be considered assumed if, following the Acquisition or Other
Combination, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the Acquisition or Other Combination, the consideration (whether stock, cash, or other securities or property) received in the
Acquisition or Other Combination by holders of Shares 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 Acquisition or Other Combination is not solely common stock of the successor corporation or its Parent, the Committee may, with the consent of the successor
corporation, provide for the consideration to be received upon the exercise of an Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit, for each Share subject to such Award, 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 Acquisition or Other Combination. 

  
 10 

 (c) The substitution by the successor or acquiring entity in such Acquisition or Other
Combination (or by any of its Parents, if any) of equivalent awards with substantially the same terms for such outstanding Awards (except that the exercise price and the number and nature of shares issuable upon exercise of any such option or stock
appreciation right, or any award that is subject to Section 409A of the Code, will be adjusted appropriately pursuant to Section 424(a) and Section 409A of the Code). 

(d) The full or partial exercisability or vesting and accelerated expiration of outstanding Awards. 

(e) The settlement of the full value of such outstanding Award (whether or not then vested or exercisable) in cash, cash equivalents, or
securities of the successor entity (or its Parent, if any) with a Fair Market Value equal to the required amount, followed by the cancellation of such Awards; provided however, that such Award may be cancelled without consideration if such Award has
no value, as determined by the Committee, in its discretion. Subject to Section 409A of the Code, such payment may be made in installments and may be deferred until the date or dates when the Award would have become exercisable or vested. Such
payment may be subject to vesting based on the Participant’s continued service, provided that without the Participant’s consent, the vesting schedule shall not be less favorable to the Participant than the schedule under which the Award
would have become vested or exercisable. For purposes of this Section 11.1(e), the Fair Market Value of any security shall be determined without regard to any vesting conditions that may apply to such security. 

(f) The cancellation of outstanding Awards in exchange for no consideration. 

Immediately following an Acquisition or Other Combination, outstanding Awards shall terminate and cease to be outstanding, except to the
extent such Awards, have been continued, assumed or substituted, as described in Sections 11.1(a), (b) and/or (c). 
 11.2
Assumption of Awards by the Company. The Company, from time to time, also may substitute or assume outstanding awards granted by another entity, whether in connection with an acquisition of such other entity or otherwise, by either
(a) granting an Award under this Plan in substitution of such other entity’s award or (b) assuming and/or converting such award as if it had been granted under this Plan if the terms of such assumed award could be applied to an Award
granted under this Plan. Such substitution or assumption will be permissible if the holder of the substituted or assumed award would have been eligible to be granted an Award under this Plan if the other entity had applied the rules of this Plan to
such grant. In the event the Company assumes an award granted by another entity, the terms and conditions of such award will remain unchanged (except that the exercise price and the number and nature of shares issuable upon exercise of any such
option or stock appreciation right, or any award that is subject to Section 409A of the Code, will be adjusted appropriately pursuant to Section 424(a) of the Code). In the event the Company elects to grant a new Option or SAR rather than
assuming an existing option or stock appreciation right, such new Option or SAR may be granted with a similarly adjusted Exercise Price. 

12. ADMINISTRATION. 

12.1 Committee Authority. This Plan will be administered by the Committee or the Board if no Committee is created by the
Board. Subject to the general purposes, terms and conditions of this Plan, and to the direction of the Board, the Committee will have full power to implement and carry out this Plan. Without limitation, the Committee will have the authority to:

(h) grant waivers of any conditions of this Plan or any Award; 

(i) determine the terms of vesting, exercisability and payment of Awards to be granted pursuant to this Plan; 

(j) correct any defect, supply any omission, or reconcile any inconsistency in this Plan, any Award, any Award Agreement, any Exercise
Agreement or any Restricted Stock Purchase Agreement; 
 (k) determine whether an Award has been earned; 

(l) extend the vesting period beyond a Participant’s Termination Date; 

(m) adopt rules and/or procedures (including the adoption of any subplan under this Plan) relating to the operation and administration of the
Plan to accommodate requirements of local law and procedures outside of the United States; 
 (n) delegate any of the foregoing to a
subcommittee consisting of one or more executive officers pursuant to a specific delegation as may otherwise be permitted by applicable law, consistent with Section 12.2 below; 

(o) change the vesting schedule of Awards under the Plan prospectively in the event that the Participant’s service status changes between
full and part time status in accordance with Company policies relating to work schedules and vesting of awards; and 
 (p) make all other
determinations necessary or advisable in connection with the administration of this Plan. 

  
 12 

 12.2 Committee Composition and Discretion. The Board may delegate full
administrative authority over the Plan and Awards to a Committee consisting of at least one member of the Board (or such greater number as may then be required by applicable law). Unless in contravention of any express terms of this Plan or
Award, any determination made by the Committee with respect to any Award will be made in its sole discretion either (a) at the time of grant of the Award, or (b) subject to Section 4.9 hereof, at any later time. Any such determination
will be final and binding on the Company and on all persons having an interest in any Award under this Plan. To the extent permitted by applicable law, the Committee may delegate to one or more directors or officers of the Company the authority to
grant an Award under this Plan. 
 12.3 Nonexclusivity of the Plan. Neither the adoption of this Plan by the Board, the
submission of this Plan to the stockholders of the Company for approval, nor any provision of this Plan will be construed as creating any limitations on the power of the Board to adopt such additional compensation arrangements as it may deem
desirable, including, without limitation, the granting of stock options and other equity awards otherwise than under this Plan, and such arrangements may be either generally applicable or applicable only in specific cases. 

12.4 Governing Law. This Plan and all agreements hereunder shall be governed by and construed in accordance with the laws
of the State of California, without giving effect to that body of laws pertaining to conflict of laws. 
 13. EFFECTIVENESS, AMENDMENT
AND TERMINATION OF THE PLAN. 
 13.1 Adoption and Stockholder Approval. This Plan will become effective
on the date that it is adopted by the Board (the “Effective Date”). This Plan will be approved by the stockholders of the Company (excluding Shares issued pursuant to this Plan), consistent with applicable laws, within twelve
(12) months before or after the Effective Date. Upon the Effective Date, the Board may grant Awards pursuant to this Plan; provided, however, that: (a) no Option or SAR may be exercised prior to initial
stockholder approval of this Plan; (b) no Option or SAR granted pursuant to an increase in the number of Shares approved by the Board shall be exercised prior to the time such increase has been approved by the stockholders of the Company;
(c) in the event that initial stockholder approval is not obtained within the time period provided herein, all Awards for which only the exemption from California’s securities qualification requirements provided by Section 25102(o)
can apply shall be canceled, any Shares issued pursuant to any such Award shall be canceled and any purchase of such Shares issued hereunder shall be rescinded; and (d) Awards (to which only the exemption from California’s securities
qualification requirements provided by Section 25102(o) can apply) granted pursuant to an increase in the number of Shares approved by the Board which increase is not approved by stockholders within the time then required under
Section 25102(o) shall be canceled, any Shares issued pursuant to any such Awards shall be canceled, and any purchase of Shares subject to any such Award shall be rescinded. 

13.2 Term of Plan. Unless earlier terminated as provided herein, this Plan will automatically terminate ten
(10) years after the Effective Date. 
 13.3 Amendment or Termination of Plan. Subject to Section 4.9 hereof,
the Board may at any time (a) terminate or amend this Plan in any respect, including without limitation amendment of any form of Award Agreement or instrument to be executed pursuant to this Plan and (b) terminate any and all outstanding
Options, SARs or RSUs upon a dissolution or liquidation of the Company, followed by the payment of creditors and the distribution of any remaining funds to the Company’s stockholders; provided, however, that the
Board will not, without the approval of the stockholders of the Company, amend this Plan in any manner that requires such stockholder approval pursuant to Section 25102(o) or pursuant to the Code or the regulations promulgated under the Code as
such provisions apply to ISO plans. The termination of the Plan, or any amendment thereof, shall not affect any Share previously issued or any Award previously granted under the Plan.

This Restricted Stock Purchase Agreement (the “Agreement”) is made and entered into as of
                                        
(the “Effective Date”) by and between Bill.Com, Inc., a Delaware corporation (the “Company”), and
                                 (“Purchaser”).
Capitalized terms not defined herein shall have the meanings ascribed to them in the Company’s 2016 Equity Incentive Plan, as may be amended from time to time (the “Plan”). 

1. PURCHASE OF SHARES. 

1.1 Agreement to Purchase and Sell Shares. On the
Effective Date and subject to the terms and conditions of this Agreement and the Plan, Purchaser hereby purchases from the Company, and the Company hereby sells to Purchaser,
                                
(                ) shares of the Company’s Common Stock (the “Shares”), at the price of
                                ($      
      ) per share (the “Purchase Price Per Share”) for a Total Purchase Price of
                            
($                            ) (the
“Purchase Price”). As used in this Agreement, the term “Shares” includes the Shares purchased under this Agreement and all securities received (a) in replacement
of the Shares, (b) as a result of stock dividends or stock splits with respect to the Shares, and (c) in replacement of the Shares in a merger, recapitalization, reorganization or similar corporate transaction. 

1.2 Payment. Purchaser hereby delivers payment of the Purchase Price as follows (check and complete as
appropriate): 
  

	[ ]	 in cash (by check) in the amount of
$                                    , receipt of which is
acknowledged by the Company. 

  

	[ ]	 by cancellation of indebtedness of the Company owed to Purchaser in the amount of
$                                         
                               . 

 

	[ ]	 by the waiver hereby of compensation due or accrued for services rendered in the amount of
$                                         
               . 

  

	[ ]	 by delivery of
                         fully-paid, nonassessable and vested shares of the Common Stock of the Company owned by Purchaser
free and clear of all liens, claims, encumbrances or security interests, valued at the current Fair Market Value of $___________ per share (a) for which the Company has received “full payment of the purchase price” within the meaning
of SEC Rule 144, (if purchased by use of a promissory note, such note has been fully paid with respect to such vested shares), or (b) that were obtained by Purchaser in the open public market. 

2. DELIVERIES. 
 2.1
Deliveries by the Purchaser. Purchaser hereby delivers to the Company at its principal executive offices: (a) this completed and signed Agreement, and (b) the Purchase Price, paid by delivery of the form of payment
specified in Section 1.2. 

  
 1 

 2.2 Deliveries by the Company. Upon its receipt of the Purchase
Price, payment or other provision for any applicable tax obligations, if any, and all the documents to be executed and delivered by Purchaser to the Company as provided herein, the Company will issue a duly executed stock certificate evidencing the
Shares in the name of Purchaser with the appropriate legends affixed thereto, to be placed in escrow as provided in Section 7.2 to secure performance of Purchaser’s obligations under Sections 5 and 6 until expiration or termination
of the Company’s Repurchase Option and Refusal Right (as such terms are defined in Sections 5 and 6, respectively). 
 3.
REPRESENTATIONS AND WARRANTIES OF PURCHASER. Purchaser represents and warrants to the Company as follows. 
 3.1 Agrees to
Terms of the Plan. Purchaser has received a copy of the Plan, has read and understands the terms of the Plan and this Agreement, and agrees to be bound by their terms and conditions. 

3.2 Acknowledgment of Tax Risks. Purchaser acknowledges that there may be adverse tax consequences upon the
purchase and the disposition of the Shares, and that Purchaser has been advised by the Company to consult a tax adviser prior to such purchase or disposition. Purchaser further acknowledges that Purchaser is not relying on the Company or its counsel
for tax advice regarding Purchaser’s purchaser or disposition of the Shares or the tax consequences to Purchaser of this Agreement. 

3.3 Shares Not Registered or Qualified. Purchaser understands and acknowledges that the Shares have not been
registered with the SEC under the Securities Act, or with any securities regulatory agency administering any state securities laws, and that, notwithstanding any other provision of this Agreement to the contrary, the purchase of any Shares is
expressly conditioned upon compliance with the Securities Act and all applicable state securities laws. Purchaser agrees to cooperate with the Company to ensure compliance with such laws. 

3.4 No Transfer Unless Registered or Exempt; Contractual Restrictions on Transfers. Purchaser understands that
Purchaser may not transfer any Shares unless such Shares are registered under the Securities Act or qualified under applicable state securities laws or unless, in the opinion of counsel to the Company, exemptions from such registration and
qualification requirements are available. Purchaser understands that only the Company may file a registration statement with the SEC and that the Company is under no obligation to do so with respect to the Shares. Purchaser has also been advised
that exemptions from registration and qualification may not be available or may not permit Purchaser to transfer all or any of the Shares in the amounts or at the times proposed by Purchaser. Purchaser further acknowledges that this Agreement
imposes additional restrictions on transfer of the Shares. 
 3.5 SEC Rule 701. Shares that are issued pursuant
to SEC Rule 701 promulgated under the Securities Act may become freely tradable by non-affiliates (under limited conditions regarding the method of sale) ninety (90) days after the first sale of
Common Stock of the Company to the general public pursuant to a registration statement filed with and declared effective by the SEC, subject to the lengthier market standoff agreement contained in Section 4 of this Agreement or any other
agreement entered into by Purchaser. Affiliates must comply with the provisions (other than the holding period requirements) of Rule 144 which permits certain limited sales of unregistered securities. Rule 144 is not presently available with
respect to the Shares and, in any event, requires that the Shares be held for a minimum of six (6) months, and in certain cases one (1) year, after they have been purchased and paid for (within the meaning of Rule 144). Purchaser
understands that use of a promissory note as payment for the Shares may not be deemed to be “full payment of the purchase price” within the meaning of Rule 144 unless certain conditions are met and that, accordingly, the Rule 144 holding
period of such Shares may not begin to run until such Shares are fully paid for within the meaning of Rule 144. Purchaser understands that Rule 144 may indefinitely restrict transfer of the Shares so long as Purchaser remains an
“affiliate” of the Company or if “current public information” about the Company (as defined in Rule 144) is not publicly available. 

  
 2 

 3.6 Access to Information. Purchaser has had access to all
information regarding the Company and its present and prospective business, assets, liabilities and financial condition that Purchaser reasonably considers important in making the decision to purchase the Shares, and Purchaser has had ample
opportunity to ask questions of the Company’s representatives concerning such matters and this investment. 
 3.7
Understanding of Risks. Purchaser is fully aware of: (a) the highly speculative nature of the investment in the Shares; (b) the financial hazards involved; (c) the lack of liquidity of the Shares and the
restrictions on transferability of the Shares (e.g., that Purchaser may not be able to sell or dispose of the Shares or use them as collateral for loans); (d) the qualifications and backgrounds of the management of the Company; and
(e) the tax consequences of investment in, and disposition of, the Shares. 
 3.8 Purchase for Own Account for
Investment. Purchaser is purchasing the Shares for Purchaser’s own account for investment purposes only and not with a view to, or for sale in connection with, a distribution of the Shares within the meaning of the Securities
Act. Purchaser has no present intention of selling or otherwise disposing of all or any portion of the Shares and no one other than Purchaser has any beneficial ownership of any of the Shares. 

3.9 No General Solicitation. At no time was Purchaser presented with or solicited by any publicly issued or
circulated newspaper, mail, radio, television or other form of general advertising or solicitation in connection with the offer, sale and purchase of the Shares. 

3.10 SEC Rule 144. Purchaser has been advised that SEC Rule 144 promulgated under the Securities Act, which permits
certain limited sales of unregistered securities, is not presently available with respect to the Shares and, in any event, requires that the Shares be held for a minimum of six (6) months, and in certain cases one (1) year, after they have
been purchased and paid for (within the meaning of Rule 144), subject to the lengthier market standoff agreement contained in Section 4 of this Agreement or any other agreement entered into by Purchaser. Purchaser understands that
Rule 144 may indefinitely restrict transfer of the Shares so long as Purchaser remains an “affiliate” of the Company or if “current public information” about the Company (as defined in Rule 144) is not publicly available. 

4. MARKET STANDOFF AGREEMENT. Subject to the provisions of this Section, Purchaser agrees in connection with any registration of the
Company’s securities under the Securities Act or other registered public offering that, Purchaser will not sell or otherwise dispose of any Shares without the prior written consent of the Company or such managing underwriters, as the case may
be, for a period of time (not to exceed one hundred eighty (180) days) after the effective date of such registration requested by such managing underwriters and subject to all restrictions as the Company or the managing underwriters may specify
for employee-stockholders generally; provided however, that if during the last seventeen (17) days of the restricted period the Company issues an earnings release or material news, or a material event relating to the Company
occurs, or prior to the expiration of the restricted period the Company announces that it will release earnings results during the sixteen (16)-day period beginning on the last day of the restricted period,
then, if required by the underwriters or the Company, for so long as, and to the extent that, Rule 2711 or any successor rule of the Financial Industry Regulatory Authority applies, the restrictions imposed by this Section 4 shall
continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. The restricted period shall in any event
terminate two (2) years after the closing date of the Company’s initial public offering. For purposes of this Section 4, the term “Company” shall include any wholly-owned subsidiary of the Company into which the Company
merges or consolidates. In order 

  
 3 

 
to enforce the foregoing covenant, the Company shall have the right to place restrictive legends on the certificates representing the shares subject to this Section and to impose stop transfer
instructions with respect to the Shares until the end of such period. Purchaser further agrees that the underwriters of any such registered public offering shall be third party beneficiaries of this Section 4 and agrees to enter into any
agreement reasonably required by the underwriters to implement the foregoing. Notwithstanding anything in this Section to the contrary, for the avoidance of doubt, the foregoing provisions of this Section shall not apply to any registration of
securities of the Company (a) under an employee benefit plan or (b) in a merger, consolidation, business combination or similar transaction.  

5. COMPANY’S REPURCHASE OPTION FOR UNVESTED SHARES. The Company, or (subject to Section 5.6) its assignee, shall have the
option to repurchase all or a portion of the Purchaser’s Shares that are Unvested Shares (as defined below) on the Termination Date on the terms and conditions set forth in this Section (the “Repurchase Option”) if
Purchaser is Terminated (as defined in the Plan) for any reason, or no reason, including without limitation, Purchaser’s death, Disability (as defined in the Plan), voluntary resignation or termination by the Company with or without Cause. 

5.1 Termination and Termination Date. In case of any dispute as to whether Purchaser is Terminated, the Committee
shall have discretion to determine in good faith whether Purchaser has been Terminated and the effective date of such Termination (the “Termination Date”). 

5.2 Vested and Unvested Shares. Shares that are vested pursuant to the schedule set forth in this Section 5.2
are “Vested Shares.” Shares that are not vested pursuant to such schedule are “Unvested Shares.” On the Effective Date, ________________ of the Shares will be Unvested Shares (the
“Initial Unvested Shares”). Provided Purchaser continues to provide services to the Company or any Subsidiary or Parent of the Company at all times from the Effective Date until ________________ (the “First Vesting
Date”), then on the First Vesting Date one-fourth (1/4th) of the Initial Unvested Shares will become Vested Shares, and on the same day
of each succeeding calendar month thereafter (or if there is no such day in any month, then the last day of such calendar month), an additional one forty-eighth 1/48th of the Initial Unvested
Shares shall vest until the earliest to occur of (a) the date all of the Shares are Vested Shares, (b) the Termination Date or (c) the date vesting otherwise terminates pursuant to this Agreement or the Plan. No fractional Shares
shall be issued. No Shares will become Vested Shares after the Termination Date. The number of the Shares that are Vested Shares or Unvested Shares will be proportionally adjusted to reflect any stock split, reverse stock split or similar change in
the capital structure of the Company as set forth in Section 2.2 of the Plan occurring after the Effective Date. 
 5.3
Exercise of Repurchase Option. At any time within ninety (90) days after the Purchaser’s Termination Date, the Company, or its assignee, may, at its option, elect to repurchase any or all the Purchaser’s
Shares that are Unvested Shares on the Termination Date by giving Purchaser written notice of exercise of the Repurchase Option, specifying the number of Unvested Shares to be repurchased. Such Unvested Shares shall be repurchased at the Purchase
Price Per Share, proportionately adjusted for any stock split, reverse stock split or similar change in the capital structure of the Company as set forth in Section 2.2 of the Plan occurring after the Effective Date (the “Repurchase
Price”). The Repurchase Price shall be payable, at the option of the Company or its assignee, by check or by cancellation of all or a portion of any outstanding indebtedness owed by Purchaser to the Company and/or such assignee, or by
any combination thereof. The Repurchase Price shall be paid without interest within the term of the Repurchase Option as described in the first sentence of this Section 5.3. The Company may, at its option, decline to exercise its Repurchase
Option or may exercise its Repurchase Option only with respect to a portion of the Unvested Shares. 
 5.4 Right of Termination
Unaffected. Nothing in this Agreement shall be construed to limit or otherwise affect in any manner whatsoever the right or power of the Company (or any Parent or Subsidiary of the Company) to terminate Purchaser’s employment or
other relationship with Company (or the Parent or Subsidiary of the Company) at any time, for any reason or no reason, with or without Cause. 

  
 4 

 5.5 Additional or Exchanged Securities and Property. Subject to
the provisions of Section 5.2 above, in the event of a merger or consolidation of the Company with or into another entity, any other corporate reorganization, a stock split, the declaration of a stock dividend, the declaration of an
extraordinary dividend payable in a form other than stock, a spin-off, a recapitalization or a similar transaction affecting the Company’s outstanding securities, any securities or other property
(including cash or cash equivalents) that are by reason of such transaction exchanged for, or distributed or issued with respect to, any Unvested Shares shall immediately be subject to the Repurchase Option. Appropriate adjustments shall be made to
the price per share to be paid for Unvested Shares upon the exercise of the Repurchase Option (by allocating such price among the Unvested Shares and such other securities or property), provided that the aggregate purchase price
payable for the Unvested Shares and all such other securities and property shall remain the same price that was original payable under the Repurchase Option to repurchase such Unvested Shares. Subject to the provisions of Section 5.2 above, in
the event of a merger or consolidation of the Company with or into another entity or any other corporate reorganization, the Repurchase Option may be exercised by the Company’s successor. 

5.6 Assignment of Repurchase Right. The Company may freely assign the Company’s Repurchase Option, in whole or
in part, provided that any person who accepts an assignment of the Repurchase Option from the Company shall assume all of the Company’s rights and obligations with respect to the Repurchase Option (to the extent so assigned) under this
Agreement. 
 6. COMPANY’S REFUSAL RIGHT. Unvested Shares shall be subject to the restrictions on transfer and the granting of
encumbrances thereon as provided in Section 7 hereof. Before any Vested Shares (as defined in Section 5 hereof) held by Purchaser or any transferee of such Vested Shares (either sometimes referred to herein as the
“Holder”) may be sold or otherwise transferred (including, without limitation, a transfer by gift or operation of law), the Company and/or its assignee(s) will have a right of first refusal to purchase the Vested Shares to be
sold or transferred (the “Offered Shares”) on the terms and conditions set forth in this Section (the “Refusal Right”). 

6.1 Notice of Proposed Transfer. The Holder of the Offered Shares will deliver to the Company a written notice (the
“Notice”) stating: (a) the Holder’s bona fide intention to sell or otherwise transfer the Offered Shares; (b) the name and address of each proposed purchaser or other transferee of Offered Shares
(“Proposed Transferee”); (c) the number of Offered Shares to be transferred to each Proposed Transferee; (d) the bona fide cash price or other consideration for which the Holder proposes to transfer the Offered Shares to
each Proposed Transferee (the “Offered Price”); and (e) that the Holder acknowledges this Notice is an offer to sell the Offered Shares to the Company and/or its assignee(s) pursuant to the Company’s Refusal Right
at the Offered Price as provided for in this Agreement. 
 6.2 Exercise of Refusal Right. At any time within
thirty (30) days after the date the Notice is effective pursuant to Section 9.2, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all (or, with the consent of the Holder, less than all) the
Offered Shares proposed to be transferred to any one or more of the Proposed Transferees named in the Notice, at the purchase price, determined as provided in Section 6.3 below. 

6.3 Purchase Price. The purchase price for the Offered Shares purchased under this Section will be the Offered
Price, provided that if the Offered Price consists of no legal consideration (as, for example, in the case of a transfer by gift), then the purchase price will be the fair market value of the Offered Shares as determined in good
faith by the Company’s Board of Directors. If the Offered Price includes consideration other than cash, then the value of the non-cash consideration, as determined in good faith by the Company’s
Board of Directors, will conclusively be deemed to be the cash equivalent value of such non-cash consideration. 

  
 5 

 6.4 Payment. The purchase price for the Offered Shares will be
paid, at the option of the Company and/or its assignee(s) (as applicable), by check or by cancellation of all or a portion of any outstanding indebtedness owed by the Holder to the Company (or to such assignee, in the case of a purchase of Offered
Shares by such assignee) or by any combination thereof. The purchase price will be paid without interest within sixty (60) days after the Company’s receipt of the Notice, or, at the option of the Company and/or its assignee(s), in the
manner and at the time(s) set forth in the Notice. 
 6.5 Holder’s Right to Transfer. If all of the Offered
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 Offered Shares to such Proposed
Transferee at the Offered Price or at a higher price, provided that (a) such sale or other transfer is consummated within one hundred twenty (120) days after the date the Notice is effective pursuant to Section 9.2, (b)
any such sale or other transfer is effected in compliance with all applicable securities laws, and (c) such Proposed Transferee agrees in writing that the provisions of this Section will continue to apply to the Offered Shares in the hands of
such Proposed Transferee. If the Offered Shares described in the Notice are not transferred to such Proposed Transferee within such one hundred twenty (120) day period, then a new Notice must be given to the Company pursuant to which the
Company will again be offered the Refusal Right before any Shares held by the Holder may be sold or otherwise transferred. 
 6.6
Exempt Transfers. Notwithstanding the foregoing, the following transfers of Vested Shares will be exempt from the Refusal Right: (a) the transfer of any or all of the Vested Shares during Purchaser’s lifetime by
gift or on Purchaser’s death by will or intestacy to Purchaser’s “Immediate Family” (as defined below) or to a trust for the benefit of Purchaser or Purchaser’s Immediate Family, provided that each transferee
agrees in a writing satisfactory to the Company that the provisions of this Section will continue to apply to the transferred Vested Shares in the hands of such transferee; (b) any transfer of Vested Shares made pursuant to a statutory merger
or statutory consolidation of the Company with or into another entity or entities (except that, subject to Section 6.7, unless the agreement of merger or consolidation expressly otherwise provides, the Refusal Right will continue to apply
thereafter to such Vested Shares, in which case the surviving entity of such merger or consolidation shall succeed to the rights of the Company under this Section); or (c) any transfer of Vested Shares pursuant to the winding up and dissolution
of the Company. As used herein, the term “Immediate Family” will mean Purchaser’s spouse, the lineal descendant or antecedent, father, mother, brother or sister, child, adopted child, grandchild or adopted grandchild of
Purchaser or Purchaser’s spouse, or the spouse of any of the above or Spousal Equivalent, as defined herein. As used herein, a person is deemed to be a “Spousal Equivalent” provided the following circumstances are true:
(i) irrespective of whether or not the Purchaser and the Spousal Equivalent are the same sex, they are the sole spousal equivalent of the other for the last twelve (12) months, (ii) they intend to remain so indefinitely, (iii) neither
are married to anyone else, (iv) both are at least 18 years of age and mentally competent to consent to contract, (v) they are not related by blood to a degree of closeness that which would prohibit legal marriage in the state in which
they legally reside, (vi) they are jointly responsible for each other’s common welfare and financial obligations, and (vii) they reside together in the same residence for the last twelve (12) months and intend to do so
indefinitely. 
 6.7 Termination of Refusal Right. The Refusal Right will terminate as to all Shares:
(a) on the effective date of the first sale of Common Stock of the Company to the public pursuant to a registration statement filed with and declared effective by the SEC under the Securities Act or, if expressly approved by the Board as
terminating the Refusal Right, under the laws of any other country having substantially the same effect (other than a registration statement relating solely to the issuance of Common Stock pursuant to a business combination or an employee incentive
or benefit plan) or (b) on any transfer or conversion of Shares made pursuant to a statutory merger or statutory consolidation of the Company with or into another entity or entities if the common stock of the surviving entity or any direct or
indirect parent entity thereof is registered under the Securities Exchange Act of 1934, as amended. 

  
 6 

 6.8 Effect of Company Co-Sale
Agreement. If Purchaser is, or at any time hereafter becomes, a party to or otherwise bound by (i) the Company’s Eighth Amended and Restated Right of First Refusal and Co-Sale
Agreement dated as of February 12, 2015 among the Company and certain stockholders of the Company, as such may be amended and/or restated from time to time, and/or (ii) any other agreement that is a successor to or replacement of such
agreement (collectively, the “Company Co-Sale Agreement”), then, in the event of any conflict or inconsistency between the provisions of this Section 6 and any provisions in the
Company Co-Sale Agreement granting the Company and/or other security holders of the Company rights of first refusal and/or co-sale rights with respect to any or all of
the Shares, Purchaser agrees with the Company that the terms and conditions of the Company Co-Sale Agreement shall apply, govern, supersede and prevail over (and in lieu of) the provisions of this
Section 6 so long as the Company Co-Sale Agreement is in effect and Purchaser is a party to or bound thereby. If the Company Co-Sale Agreement is no longer in
effect or if Purchaser is not a party to or bound thereby, then the provisions of this Section 6 shall apply in full force and effect until termination of the Right of First Refusal. 

7. ADDITIONAL RESTRICTIONS UPON SHARE OWNERSHIP OR TRANSFER. 

7.1 Rights as a Stockholder. Subject to the terms and conditions of this Agreement, Purchaser will have all of the
rights of a Stockholder of the Company with respect to the Shares from and after the date that Shares are issued to Purchaser until such time as Purchaser disposes of the Shares or the Company and/or its assignee(s) exercise(s) the Refusal Right or
the Repurchase Option. Upon an exercise of the Refusal Right or the Repurchase Option, Purchaser will have no further rights as a holder of the Shares so purchased upon such exercise, other than the right to receive payment for the Shares so
purchased in accordance with the provisions of this Agreement, and Purchaser will promptly surrender the stock certificate(s) evidencing the Shares so purchased to the Company for transfer or cancellation. 

7.2 Escrow. As security for Purchaser’s faithful performance of this Agreement, Purchaser agrees, immediately
upon receipt of the stock certificate(s) evidencing the Shares, to deliver such certificate(s) to the Secretary of the Company or other designee of the Company (the “Escrow Holder”), who is hereby appointed to hold such
certificate(s) in escrow and to take all such actions and to effectuate all such transfers and/or releases of such Shares as are in accordance with the terms of this Agreement. Purchaser and the Company agree that Escrow Holder will not be liable to
any party to this Agreement (or to any other person or entity) for any actions or omissions unless Escrow Holder is grossly negligent or intentionally fraudulent in carrying out the duties of Escrow Holder under this Agreement. Escrow Holder may
rely upon any letter, notice or other document executed with any signature purported to be genuine and may rely on the advice of counsel and obey any order of any court with respect to the transactions contemplated by this Agreement. The Shares will
be released from escrow upon termination of both the Refusal Right and the Repurchase Option. 
 7.3 Encumbrances on
Shares. Without the Company’s prior written consent given with the approval of the Company’s Board of Directors, Purchaser may not grant a lien or security interest in, or pledge, hypothecate or encumber, any Unvested
Shares. 
 7.4 Restrictions on Transfers. Unvested Shares may not be sold or otherwise transferred by Purchaser
without the Company’s prior written consent. Purchaser hereby agrees that Purchaser shall make no disposition of the Shares (other than as permitted by this Agreement) unless and until: 

  
 7 

 (a) Purchaser shall have notified the Company of the proposed disposition
and provided a written summary of the terms and conditions of the proposed disposition; 
 (b) Purchaser shall have complied
with all requirements of this Agreement applicable to the disposition of the Shares, including but not limited to the Refusal Right, the Market Standoff and the Repurchase Option; and 

(c) Purchaser shall have provided the Company with written assurances, in form and substance satisfactory to counsel for the
Company, that (i) the proposed disposition does not require registration of the Shares under the Securities Act or under any state securities laws, and (ii) all appropriate actions necessary for compliance with the registration and
qualification requirements of the Securities Act and any state securities laws, or of any exemption from registration or qualification, available thereunder (including Rule 144) have been taken. 

Each person (other than the Company) to whom the Shares are transferred by means of one of the permitted transfers specified in this Agreement must, as a
condition precedent to the validity of such transfer, acknowledge in writing to the Company that such person is bound by the provisions of this Agreement and that the transferred Shares are subject to the Company’s Refusal Right or the
Repurchase Option granted hereunder and the market stand-off provisions of Section 4 hereof, to the same extent such Shares would be so subject if retained by the Purchaser. 

7.5 Restrictive Legends and Stop-transfer Orders. Purchaser understands and agrees that the Company will place the
legends set forth below or similar legends on any stock certificate(s) evidencing the Shares, together with any other legends that may be required by applicable laws, the Company’s Certificate of Incorporation or Bylaws, any other agreement
between Purchaser and the Company or any agreement between Purchaser and any third party: 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR
RESOLD EXCEPT AS PERMITTED UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN
INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE SECURITIES ACT AND ANY
APPLICABLE STATE SECURITIES LAWS. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON PUBLIC RESALE
AND TRANSFER, INCLUDING THE RIGHT OF FIRST REFUSAL AND THE REPURCHASE OPTION HELD BY THE ISSUER AND/OR ITS ASSIGNEE(S), AND A MARKET STANDOFF AGREEMENT, AS SET FORTH IN A RESTRICTED STOCK PURCHASE 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 PUBLIC SALE AND TRANSFER RESTRICTIONS INCLUDING THE RIGHT OF FIRST REFUSAL, THE REPURCHASE OPTION AND THE MARKET STANDOFF ARE
BINDING ON TRANSFEREES OF THESE SHARES. 

  
 8 

 Purchaser agrees that if Purchaser becomes a party to (i) the Company
Co-Sale Agreement or (ii) (A) the Company’s Eighth Amended and Restated Voting Agreement dated as of February 12, 2015 among the Company and certain stockholders of the Company, as such may be
amended and/or restated from time to time, and/or (B) any other voting agreement that is a successor to or replacement of such agreement (collectively, the “Company Voting Agreement”), then Purchaser agrees that the
stock certificate(s) evidencing the Shares shall, in addition, bear any legends required under the Company Co-Sale Agreement and/or the Company Voting Agreement, as applicable. 

Purchaser also agrees that, to ensure compliance with the restrictions imposed by this Agreement, the Company may issue appropriate “stop-transfer”
instructions to its transfer agent, if any, and if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. The Company will not be required (a) 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 (b) 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
have been so transferred. 
 8. TAX CONSEQUENCES. PURCHASER UNDERSTANDS THAT PURCHASER MAY SUFFER ADVERSE TAX
CONSEQUENCES AS A RESULT OF PURCHASER’S PURCHASE OR DISPOSITION OF THE SHARES. PURCHASER REPRESENTS (a) THAT PURCHASER HAS CONSULTED WITH ANY TAX ADVISER THAT PURCHASER DEEMS ADVISABLE IN CONNECTION WITH THE PURCHASE OR
DISPOSITION OF THE SHARES AND (b) THAT PURCHASER IS NOT RELYING ON THE COMPANY FOR ANY TAX ADVICE. Purchaser hereby acknowledges that Purchaser has been informed that, with respect to Unvested Shares, unless an election is
filed by Purchaser with the Internal Revenue Service (and, if necessary, the proper state taxing authorities) within 30 days after the purchase of the Shares electing, pursuant to Section 83(b) of the Internal Revenue Code (and
similar state tax provisions, if applicable), to be taxed currently on any difference between the Purchase Price of the Unvested Shares and their Fair Market Value on the date of purchase, there will be a recognition of taxable income to Purchaser,
measured by the excess, if any, of the Fair Market Value of the Unvested Shares, at the time they cease to be Unvested Shares, over the Purchase Price for such Shares. Purchaser represents that Purchaser has consulted any tax advisers Purchaser
deems advisable in connection with Purchaser’s purchase of the Shares and the filing of the election under Section 83(b) and similar tax provisions. A form of Election under Section 83(b) is attached hereto as
Exhibit 1 for reference. BY PROVIDING THE FORM OF ELECTION, NEITHER THE COMPANY NOR ITS LEGAL COUNSEL IS THEREBY UNDERTAKING TO FILE THE ELECTION FOR PURCHASER, WHICH OBLIGATION TO FILE SHALL
REMAIN SOLELY WITH PURCHASER. 
 9. GENERAL PROVISIONS. 

9.1 Successors and Assigns. The Company may assign any of its rights under this Agreement, including its rights to
purchase Shares under the Refusal Right or the Repurchase Option. Neither Purchaser, nor any of Purchaser’s successors and assigns, may assign, whether voluntarily or by operation of law, any of its rights and obligations under this Agreement,
except with the prior written consent of the Company. This Agreement shall be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Agreement will be
binding upon Purchaser and Purchaser’s heirs, executors, administrators, legal representatives, successors and assigns.

such other party may designate by one of the indicated means of notice herein to the other parties hereto or, in the case of the Company, to it at its principal place of business. Notices to the Company will be marked “Attention: Chief
Financial Officer.” Notices by facsimile shall be machine verified as received. 
 9.3 Further Assurances.
The parties agree to execute such further documents and instruments and to take such further actions as may be reasonably necessary to carry out the purposes and intent of this Agreement.

subject matter hereof. 
 9.5 Severability. If any provision of this Agreement is determined by any court or
arbitrator of competent jurisdiction to be invalid, illegal or unenforceable in any respect, such provision will be enforced to the maximum extent possible given the intent of the parties hereto. If such clause or provision cannot be so enforced,
such provision shall be stricken from this Agreement and the remainder of this Agreement shall be enforced as if such invalid, illegal or unenforceable clause or provision had (to the extent not enforceable) never been contained in this Agreement.
Notwithstanding the forgoing, if the value of this Agreement based upon the substantial benefit of the bargain for any party is materially impaired, which determination as made by the presiding court or arbitrator of competent jurisdiction shall be
binding, then both parties agree to substitute such provision(s) through good faith negotiations.

and in favor of certain material transactions (such as mergers or sales of the Company), then Purchaser will enter into such agreements and execute and deliver signature pages thereto (as requested by the Company) in such capacities and at such time
as the Company requests. 
 9.7 Execution. This Agreement may be entered into in two or more counterparts, each
of which shall be deemed an original and all of which shall constitute one and the same agreement. This Agreement may be executed and delivered by facsimile and, upon such delivery, the facsimile signature will be deemed to have the same effect as

STOCK OPTION AGREEMENT 

BILL.COM, INC. 

2016 EQUITY INCENTIVE PLAN 

This Stock Option Agreement (this “Agreement”) is made and entered into as of the date of grant (the “Date
of Grant”) set forth on the Notice of Stock Option Grant attached as the facing page to this Agreement (the “Grant Notice”) by and between Bill.Com, Inc., a Delaware corporation (the
“Company”), and the optionee named on the Grant Notice (“Optionee”). Capitalized terms not defined in this Agreement shall have the meaning ascribed to them in the Company’s 2016 Equity Incentive
Plan, as amended from time to time (the “Plan”), or in the Grant Notice, as applicable. 
 1. GRANT OF
OPTION. The Company hereby grants to Optionee an option (this “Option”) to purchase up to the total number of shares of Common Stock of the Company, $0.00001 par value per share (the “Common
Stock”), set forth in the Grant Notice as the Shares (the “Shares”) at the Exercise Price Per Share set forth in the Grant Notice (the “Exercise Price”), subject to all of the terms and
conditions of the Grant Notice, this Agreement and the Plan. If designated as an Incentive Stock Option in the Grant Notice, this Option is intended to qualify as an incentive stock option (the “ISO”) within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), except that if on the Date of Grant Optionee is not subject to U.S. income tax, then this Option shall be a NQSO. 

2. EXERCISE PERIOD. 

2.1 Exercise Period of Option. This Option is considered to be “vested” with respect to any particular
Shares when this Option is exercisable with respect to such Shares. This Option will become vested during its term as to portions of the Shares in accordance with the Vesting Schedule set forth in the Grant Notice. Notwithstanding any provision in
the Plan or this Agreement to the contrary, on or after Optionee’s Termination Date, this Option may not be exercised with respect to any Shares that are Unvested Shares on Optionee’s Termination Date. 

2.2 Vesting of Option Shares. Shares with respect to which this Option is vested and exercisable at a given time
pursuant to the Vesting Schedule set forth in the Grant Notice are “Vested Shares.” Shares with respect to which this Option is not vested and exercisable at a given time pursuant to the Vesting Schedule set forth in
the Grant Notice are “Unvested Shares.” 
 2.3 Expiration. The Option shall
expire on the Expiration Date set forth in the Grant Notice or earlier as provided in Section 3 below. 
 3. TERMINATION. 

3.1 Termination for Any Reason Except Death, Disability or Cause. Except as provided in subsection 3.2 in a case in
which Optionee dies within three (3) months after Optionee is Terminated other than for Cause, if Optionee is Terminated for any reason (other than Optionee’s death or Disability or for Cause), then (a) on and after
Optionee’s Termination Date, this Option shall expire immediately with respect to any Shares that are Unvested Shares and may not be exercised with respect to any Shares that are Unvested Shares on Optionee’s Termination Date and
(b) this Option to the extent (and only to the extent) that it is exercisable with respect to Vested Shares on Optionee’s Termination Date, may be exercised by Optionee no later than three (3) months after Optionee’s
Termination Date (but in no event may this Option be exercised after the Expiration Date). 

 3.2 Termination Because of Death or Disability. If Optionee is
Terminated because of Optionee’s death or Disability (or if Optionee dies within three (3) months of the date of Optionee’s Termination for any reason other than for Cause), then (a) on and after Optionee’s Termination Date,
this Option shall expire immediately with respect to any Shares that are Unvested Shares and may not be exercised with respect to any Shares that are Unvested Shares on Optionee’s Termination Date and (b) this Option, to the extent (and
only to the extent) that it is exercisable with respect to Vested Shares on Optionee’s Termination Date, may be exercised by Optionee (or Optionee’s legal representative) no later than twelve (12) months after Optionee’s
Termination Date, but in no event later than the Expiration Date. Any exercise of this Option beyond (i) three (3) months after the date Optionee ceases to be an employee when Optionee’s Termination is for any reason other than
Optionee’s death or disability, within the meaning of Section 22(e)(3) of the Code; or (ii) twelve (12) months after the date Optionee ceases to be an employee when the termination is for Optionee’s disability, within the
meaning of Section 22(e)(3) of the Code, is deemed to be an NQSO. 
 3.3 Termination for Cause. If Optionee
is Terminated for Cause, then Optionee may exercise this Option, but only with respect to any Shares that are Vested Shares on Optionee’s Termination Date, and this Option shall expire on Optionee’s Termination Date, or at such
later time and on such conditions as may be affirmatively determined by the Committee. On and after Optionee’s Termination Date, this Option shall expire immediately with respect to any Shares that are Unvested Shares and may not be exercised
with respect to any Shares that are Unvested Shares on Optionee’s Termination Date. 
 3.4 No Obligation to
Employ. Nothing in the Plan or this Agreement shall confer on Optionee any right to continue in the employ of, or other relationship with, the Company or any Parent or Subsidiary of the Company, or limit in any way the right of the
Company or any Parent or Subsidiary of the Company to terminate Optionee’s employment or other relationship at any time, with or without Cause. 

4. MANNER OF EXERCISE. 

4.1 Stock Option Exercise Notice and Agreement. To exercise this Option, Optionee (or in the case of exercise after
Optionee’s death or incapacity, Optionee’s executor, administrator, heir or legatee, as the case may be) must deliver to the Company an executed Stock Option Exercise Notice and Agreement in the form attached hereto as
Annex A, or in such other form as may be approved by the Committee from time to time (the “Exercise Agreement”) and payment for the shares being purchased in accordance with this
Agreement. The Exercise Agreement shall set forth, among other things, (i) Optionee’s election to exercise this Option, (ii) the number of Shares being purchased,    (iii) any representations, warranties and
agreements regarding Optionee’s investment intent and access to information as may be required by the Company to comply with applicable securities laws in connection with any exercise of this Option and (iv) any other agreements required
by the Company. If someone other than Optionee exercises this Option, then such person must submit documentation reasonably acceptable to the Company verifying that such person has the legal right to exercise this Option and such person shall be
subject to all of the restrictions contained herein as if such person were Optionee. 
 4.2 Limitations on
Exercise. This Option may not be exercised unless such exercise is in compliance with all applicable federal and state securities laws, as they are in effect on the date of exercise. 

4.3 Payment. The Exercise Agreement shall be accompanied by full payment of the Exercise Price for the shares being
purchased in cash (by check or wire transfer), or where permitted by law: 
 (a) by cancellation of indebtedness of the Company owed to
Optionee; 

  
 3 

 (b) by surrender of shares of the Company that are free and clear of all security
interests, pledges, liens, claims or encumbrances and: (i) for which the Company has received “full payment of the purchase price” within the meaning of SEC Rule 144 (and, if such shares were purchased from the Company by use of
a promissory note, such note has been fully paid with respect to such shares) or (ii) that were obtained by Optionee in the public market; 

(c) by participating in a formal cashless exercise program implemented by the Committee in connection with the Plan; 

(d) provided that a public market for the Common Stock exists and subject to compliance with applicable law, by exercising as set forth below,
through a “same day sale” commitment from Optionee and a broker-dealer whereby Optionee irrevocably elects to exercise this Option and to sell a portion of the Shares so purchased sufficient to pay the total Exercise Price, and whereby the
broker-dealer irrevocably commits upon receipt of such Shares to forward the total Exercise Price directly to the Company; or 
 (e) by any
combination of the foregoing or any other method of payment approved by the Committee that constitutes legal consideration for the issuance of Shares. 

4.4 Tax Withholding. Prior to the issuance of the Shares upon exercise of the Option, Optionee must pay or provide
for any applicable federal, state and local withholding obligations of the Company. If the Committee permits, Optionee may provide for payment of withholding taxes upon exercise of the Option by requesting that the Company retain the minimum number
of Shares with a Fair Market Value equal to the minimum amount of taxes required to be withheld; or to arrange a mandatory “sell to cover” on Participant’s behalf (without further authorization); but in no event will the Company
withhold Shares or “sell to cover” if such withholding would result in adverse accounting consequences to the Company. In case of stock withholding or a sell to cover, the Company shall issue the net number of Shares to Optionee by
deducting the Shares retained from the Shares issuable upon exercise. 
 4.5 Issuance of Shares. Provided that
the Exercise Agreement and payment are in form and substance satisfactory to counsel for the Company, the Company shall issue the Shares issuable upon a valid exercise of this Option registered in the name of Optionee, Optionee’s authorized
assignee, or Optionee’s legal representative, and shall deliver certificates representing the Shares with the appropriate legends affixed thereto. 

5. COMPLIANCE WITH LAWS AND REGULATIONS. The Plan
and this Agreement are intended to comply with Section 25102(o) and Rule 701. Any provision of this Agreement that is inconsistent with Section 25102(o) or Rule 701 shall, without further act or amendment by the Company or the Committee,
be reformed to comply with the requirements of Section 25102(o) and/or Rule 701. The exercise of this Option and the issuance and transfer of Shares shall be subject to compliance by the Company and Optionee with all applicable
requirements of federal and state securities laws and with all applicable requirements of any stock exchange on which the Common Stock may be listed at the time of such issuance or transfer. Optionee understands that the Company is under no
obligation to register or qualify the Shares with the SEC, any state securities commission or any stock exchange to effect such compliance. 

6. NONTRANSFERABILITY OF OPTION. This Option may not be transferred in any manner
other than by will or by the laws of descent and distribution, and, with respect to NQSOs, by instrument to a testamentary trust in which the options are to be passed to beneficiaries upon the death of the trustor (settlor) or a revocable trust, or
by gift to “immediate family” as that term is defined in 17 C.F.R. 240.16a-1(e), and may be exercised during the lifetime of Optionee only by Optionee or in the event of Optionee’s incapacity,
by Optionee’s legal representative. The terms of this Option shall be binding upon the executors, administrators, successors and assigns of Optionee. 

  
 4 

 7. RESTRICTIONS ON TRANSFER. 

7.1 Disposition of Shares. Optionee hereby agrees that Optionee shall make no disposition of any of the Shares
(other than as permitted by this Agreement) unless and until: 
 (a) Optionee shall have notified the Company of the proposed disposition
and provided a written summary of the terms and conditions of the proposed disposition; 
 (b) Optionee shall have complied with all
requirements of this Agreement applicable to the disposition of the Shares; 
 (c) Optionee shall have provided the Company with written
assurances, in form and substance satisfactory to counsel for the Company, that (i) the proposed disposition does not require registration of the Shares under the Securities Act or under any applicable state securities laws or (ii) all
appropriate actions necessary for compliance with the registration requirements of the Securities Act or of any exemption from registration available under the Securities Act (including Rule 144) or applicable state securities laws have been taken;
and 
 (d) Optionee shall have provided the Company with written assurances, in form and substance satisfactory to the Company, that the
proposed disposition will not result in the contravention of any transfer restrictions applicable to the Shares pursuant to the provisions of the regulations promulgated under Section 25102(o), Rule 701 or under any other applicable securities
laws or adversely affect the Company’s ability to rely on the exemption(s) from registration under the Securities Act or under any other applicable securities laws for the grant of the Option, the issuance of Shares thereunder or any other
issuance of securities under the Plan. 
 7.2 Restriction on Transfer. Optionee shall not transfer, assign, grant
a lien or security interest in, pledge, hypothecate, encumber or otherwise dispose of any of the Shares which are subject to the Company’s Right of First Refusal described below, except as permitted by this Agreement. 

7.3 Transferee Obligations. Each person (other than the Company) to whom the Shares are transferred by means of one
of the permitted transfers specified in this Agreement must, as a condition precedent to the validity of such transfer, acknowledge in writing to the Company that such person is bound by the provisions of this Agreement and that the transferred
Shares are subject to (i) the Company’s Right of First Refusal granted hereunder and (ii) the market stand-off provisions of Section 8 below, to the same extent such Shares would be so
subject if retained by Optionee. 
 8. MARKET STANDOFF AGREEMENT. Optionee agrees that, subject to any early release
provisions that apply pro rata to stockholders of the Company according to their holdings of Common Stock (determined on an as-converted into Common Stock basis), Optionee will not, for a period of up to one
hundred eighty (180) days (plus up to an additional thirty five (35) days to the extent reasonably requested by the Company or such underwriter(s) to accommodate regulatory restrictions on the publication or other distribution of research
reports or earnings releases by the Company, including NASD and NYSE rules) following the effective date of the registration statement filed with the SEC relating to the initial underwritten sale of Common Stock of the Company to the public under
the Securities Act (the “IPO”), directly or indirectly sell, offer to sell, grant any option for the sale of, or otherwise dispose of any Common Stock or securities convertible into Common Stock, except for:
(i) transfers of Shares permitted under Section 9.6 hereof so long as such transferee furnishes to the Company and the managing underwriter their written consent to be bound by this Section 8 as a condition precedent to such transfer;
and (ii) sales of any securities to be included in the registration statement for the IPO. For the avoidance of doubt, the provisions of this Section shall only apply to the IPO. The restricted period shall in any event terminate two
(2) years after the closing date of the IPO. In order to enforce the foregoing covenant, the Company shall have the right to place restrictive legends on the certificates representing the Shares subject to this Section and to impose stop
transfer instructions with 

  
 5 

 
respect to the Shares until the end of such period. Optionee further agrees to enter into any agreement reasonably required by the underwriters to implement the foregoing restrictions on
transfer. For the avoidance of doubt, the foregoing provisions of this Section shall not apply to any registration of securities of the Company (a) under an employee benefit plan or (b) in a merger, consolidation, business combination or
similar transaction. 
 9. COMPANY’S RIGHT OF FIRST REFUSAL. Before any Shares held by Optionee or any transferee of such
Shares (either sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including, without limitation, a transfer by gift or operation of law), the Company and/or its assignee(s) will have a right
of first refusal to purchase the Shares to be sold or transferred (the “Offered Shares”) on the terms and conditions set forth in this Section (the “Right of First Refusal”). 

9.1 Notice of Proposed Transfer. The Holder of the Offered Shares will deliver to the Company a written notice (the
“Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer the Offered Shares; (ii) the name and address of each proposed purchaser or other transferee (the “Proposed
Transferee”); (iii) the number of Offered Shares to be transferred to each Proposed Transferee; (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Offered Shares (the
“Offered Price”); and (v) that the Holder acknowledges this Notice is an offer to sell the Offered Shares to the Company and/or its assignee(s) pursuant to the Company’s Right of First Refusal at the Offered Price
as provided for in this Agreement. 
 9.2 Exercise of Right of First Refusal. At any time within thirty
(30) days after the date of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all (or, with the consent of the Holder, less than all) the Offered Shares proposed to be transferred to
any one or more of the Proposed Transferees named in the Notice, at the purchase price, determined as specified below. 
 9.3
Purchase Price. The purchase price for the Offered Shares purchased under this Section will be the Offered Price, provided that if the Offered Price consists of no legal consideration (as, for example, in the
case of a transfer by gift) then the purchase price will be the fair market value of the Offered Shares as determined in good faith by the Committee. If the Offered Price includes consideration other than cash, then the value of the non-cash consideration, as determined in good faith by the Committee, will conclusively be deemed to be the cash equivalent value of such non-cash consideration. 

9.4 Payment. Payment of the purchase price for the Offered Shares will be payable, at the option of the Company
and/or its assignee(s) (as applicable), by check or by cancellation of all or a portion of any outstanding purchase money indebtedness owed by the Holder to the Company (or to such assignee, in the case of a purchase of Offered Shares by such
assignee) or by any combination thereof. The purchase price will be paid without interest within sixty (60) days after the Company’s receipt of the Notice, or, at the option of the Company and/or its assignee(s), in the manner and at the
time(s) set forth in the Notice. 
 9.5 Holder’s Right to Transfer. If all of the Offered 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 Offered Shares to each Proposed Transferee at the
Offered Price or at a higher price, provided that (i) such sale or other transfer is consummated within ninety (90) days after the date of the Notice, (ii) any such sale or other transfer is effected in compliance with
all applicable securities laws, and (iii) each Proposed Transferee agrees in writing that the provisions of this Section will continue to apply to the Offered Shares in the hands of such Proposed Transferee. If the Offered Shares described in
the Notice are not transferred to each Proposed Transferee within such ninety (90) day period, then a new Notice must be given to the Company pursuant to which the Company will again be offered the Right of First Refusal before any Shares held
by the Holder may be sold or otherwise transferred. 

  
 6 

 9.6 Exempt Transfers. Notwithstanding anything to the contrary
in this Section, the following transfers of Shares will be exempt from the Right of First Refusal: (i) the transfer of any or all of the Shares during Optionee’s lifetime by gift or on Optionee’s death by will or intestacy to any
member(s) of Optionee’s “Immediate Family” (as defined below) or to a trust for the benefit of Optionee and/or member(s) of Optionee’s Immediate Family, provided that each transferee or other recipient agrees in a
writing satisfactory to the Company that the provisions of this Section will continue to apply to the transferred Shares in the hands of such transferee or other recipient; (ii) any transfer of Shares made pursuant to a statutory merger,
statutory consolidation of the Company with or into another corporation or corporations or a conversion of the Company into another form of legal entity (except that the Right of First Refusal will continue to apply thereafter to such Shares, in
which case the surviving corporation of such merger or consolidation or the resulting entity of such conversion shall succeed to the rights of the Company under this Section unless the agreement of merger or consolidation or conversion expressly
otherwise provides); or (iii) any transfer of Shares pursuant to the winding up and dissolution of the Company. As used herein, the term “Immediate Family” will mean Optionee’s spouse, the lineal descendant or
antecedent, father, mother, brother or sister, child, adopted child, grandchild or adopted grandchild of Optionee or Optionee’s spouse, or the spouse of any of the above or Spousal Equivalent, as defined herein. As used herein, a person is
deemed to be a “Spousal Equivalent” provided the following circumstances are true: (i) irrespective of whether or not Optionee and the Spousal Equivalent are the same sex, they are the sole spousal equivalent of the
other for the last twelve (12) months, (ii) they intend to remain so indefinitely, (iii) neither are married to anyone else, (iv) both are at least 18 years of age and mentally competent to consent to contract, (v) they are not
related by blood to a degree of closeness that which would prohibit legal marriage in the state in which they legally reside, (vi) they are jointly responsible for each other’s common welfare and financial obligations, and (vii) they
reside together in the same residence for the last twelve (12) months and intend to do so indefinitely. 
 9.7 Termination
of Right of First Refusal. The Right of First Refusal will terminate as to all Shares: (i) on the effective date of the first sale of Common Stock of the Company to the general public pursuant to a registration statement
filed with and declared effective by the SEC under the Securities Act (other than a registration statement relating solely to the issuance of Common Stock pursuant to a business combination or an employee incentive or benefit plan); (ii) on any
transfer or conversion of Shares made pursuant to a statutory merger or statutory consolidation of the Company with or into another corporation or corporations if the common stock of the surviving corporation or any direct or indirect parent
corporation thereof is registered under the Exchange Act; or (iii) on any transfer or conversion of Shares made pursuant to a statutory conversion of the Company into another form of legal entity if the common equity (or comparable
equity security) of entity resulting from such conversion is registered under the Exchange Act. 
 9.8 Encumbrances on
Shares. Optionee may grant a lien or security interest in, or pledge, hypothecate or encumber Shares only if each party to whom such lien or security interest is granted, or to whom such pledge, hypothecation or other encumbrance is
made, agrees in a writing satisfactory to the Company that: (i) such lien, security interest, pledge, hypothecation or encumbrance will not adversely affect or impair the Right of First Refusal or the rights of the Company and/or its
assignee(s) with respect thereto and will not apply to such Shares after they are acquired by the Company and/or its assignees under this Section; and (ii) the provisions of this Agreement will continue to apply to such Shares in the hands of
such party and any transferee of such party. 
 9.9 Effect of Company Co-Sale
Agreement. If Optionee is, or at any time hereafter becomes, a party to or otherwise bound by (i) the Company’s Eighth Amended and Restated Right of First Refusal and Co-Sale Agreement
dated as of February 12, 2015 among the Company and certain stockholders of the Company, as such may be amended and/or restated from time to time, and/or (ii) any other agreement that is a successor to or replacement of such agreement
(collectively, the “Company Co-Sale Agreement”), then, in the event of any conflict or inconsistency between the provisions of this Section 9 and any provisions in the Company Co-Sale Agreement granting the Company and/or other 

  
 7 

 
security holders of the Company rights of first refusal and/or co-sale rights with respect to any or all of the Shares, Optionee agrees with the Company
that the terms and conditions of the Company Co-Sale Agreement shall apply, govern, supersede and prevail over (and in lieu of) the provisions of this Section 9 so long as the Company Co-Sale Agreement is in effect and Optionee is a party to or bound thereby. If the Company Co-Sale Agreement is no longer in effect or if Optionee is not a party to or bound
thereby, then the provisions of this Section 9 shall apply in full force and effect until termination of the Right of First Refusal. 

10. RIGHTS AS A STOCKHOLDER. Optionee shall not have any of the rights of a stockholder with respect to any Shares unless and
until such Shares are issued to Optionee. Subject to the terms and conditions of this Agreement, Optionee will have all of the rights of a stockholder of the Company with respect to the Shares from and after the date that Shares are issued to
Optionee pursuant to, and in accordance with, the terms of the Exercise Agreement until such time as Optionee disposes of the Shares or the Company and/or its assignee(s) exercise(s) the Right of First Refusal. Upon an exercise of the Right of First
Refusal, Optionee will have no further rights as a holder of the Shares so purchased upon such exercise, other than the right to receive payment for the Shares so purchased in accordance with the provisions of this Agreement, and Optionee will
promptly surrender the stock certificate(s) evidencing the Shares so purchased to the Company for transfer or cancellation. 
 11.
ESCROW. As security for Optionee’s faithful performance of this Agreement, Optionee agrees, immediately upon receipt of the stock certificate(s) evidencing the Shares, to deliver such certificate(s) to the Secretary of the Company or
other designee of the Company (the “Escrow Holder”), who is hereby appointed to hold such certificate(s) in escrow and to take all such actions and to effectuate all such transfers and/or releases of such Shares as are in
accordance with the terms of this Agreement. Optionee and the Company agree that Escrow Holder will not be liable to any party to this Agreement (or to any other party) for any actions or omissions unless Escrow Holder is grossly negligent or
intentionally fraudulent in carrying out the duties of Escrow Holder under this Agreement. Escrow Holder may rely upon any letter, notice or other document executed with any signature purported to be genuine and may rely on the advice of counsel and
obey any order of any court with respect to the transactions contemplated by this Agreement and will not be liable for any act or omission taken by Escrow Holder in good faith reliance on such documents, the advice of counsel or a court order. The
Shares will be released from escrow upon termination of the Right of First Refusal. 
 12. Company Co-Sale Agreementand Voting Agreement. As a material inducement and consideration for the Company to enter into this Agreement, Optionee hereby agrees that if, the Company requests Optionee to enter
into and become a party to (a) the Company Co-Sale Agreement (and to subject the Shares to the rights of first refusal held by the Company and other Company investors thereunder and the co-sale rights of other investors thereunder) and/or (b) the Company Voting Agreement (pursuant to which Optionee would agree to vote all shares of Company stock held by Optionee for the election of directors
and in favor of certain material transactions (such as mergers or sales of the Company), then Optionee will enter into such agreements and execute and deliver signature pages thereto (as requested by the Company) in such capacities as the Company
requests, at the time of exercising this Option and as a condition to such exercise or at any later time. 
 13. RESTRICTIVE LEGENDS AND
STOP-TRANSFER ORDERS. 
 13.1 Legends. Optionee understands and agrees that the Company will place the
legends set forth below or similar legends on any stock certificate(s) evidencing the Shares, together with any other legends that may be required by state or U.S. Federal securities laws, the Company’s Certificate of Incorporation or Bylaws,
any other agreement between Optionee and the Company, or any agreement between Optionee and any third party (and any other legend(s) that the Company may become obligated to place on the stock certificate(s) evidencing the Shares under the terms of
any agreement to which the Company is or may become bound or obligated):

 (a) THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE “SECURITIES ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE
SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF
THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS. 

(b) THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON RESALE AND TRANSFER, INCLUDING THE RIGHT OF FIRST
REFUSAL HELD BY THE ISSUER AND/OR ITS ASSIGNEE(S) AS SET FORTH IN A STOCK OPTION 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 SALE AND TRANSFER
RESTRICTIONS, INCLUDING THE RIGHT OF FIRST REFUSAL, ARE BINDING ON TRANSFEREES OF THESE SHARES. 
 (c) THE SHARES REPRESENTED BY THIS
CERTIFICATE ARE SUBJECT TO A MARKET STANDOFF RESTRICTION AS SET FORTH IN A CERTAIN STOCK OPTION 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. AS A RESULT
OF SUCH AGREEMENT, THESE SHARES MAY NOT BE TRADED PRIOR TO 180 DAYS (AND POSSIBLY LONGER) AFTER THE EFFECTIVE DATE OF CERTAIN PUBLIC OFFERINGS OF THE COMMON STOCK OF THE ISSUER HEREOF. SUCH RESTRICTION IS BINDING ON TRANSFEREES OF THESE SHARES. 

Optionee agrees that if Optionee becomes a party to (i) the Company Co-Sale Agreement or (ii) (A) the
Company’s Eighth Amended and Restated Voting Agreement dated as of February 12, 2015 among the Company and certain stockholders of the Company, as such may be amended and/or restated from time to time, and/or (B) any other voting
agreement that is a successor to or replacement of such agreement (collectively, the “Company Voting Agreement”), then Optionee agrees that the stock certificate(s) evidencing the Shares shall, in addition, bear any legends
required under the Company Co-Sale Agreement and/or the Company Voting Agreement, as applicable. 

13.2 Stop-Transfer Instructions. Optionee agrees that, to ensure compliance with the restrictions imposed by this
Agreement, the Company may issue appropriate “stop-transfer” instructions to its transfer agent, if any, and if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 

13.3 Refusal to Transfer. The Company will 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 have
been so transferred. 
 14. CERTAIN TAX CONSEQUENCES. Set forth below is a brief summary as of the Effective Date of the Plan
of some of the federal tax consequences of exercise of the Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING
THE OPTION OR DISPOSING OF THE SHARES. 

  
 9 

 14.1 Exercise of ISO. If the Option qualifies as an ISO, there
will be no regular federal income tax liability upon the exercise of the Option, although the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price will be treated as a tax preference item for federal
alternative minimum tax purposes and may subject Optionee to the alternative minimum tax in the year of exercise. 
 14.2
Exercise of Nonqualified Stock Option. If the Option does not qualify as an ISO, there may be a regular federal income tax liability upon the exercise of the Option. Optionee will be treated as having received compensation
income (taxable at ordinary income tax rates) equal to the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price. If Optionee is a current or former employee of the Company, the Company may be
required to withhold from Optionee’s compensation or collect from Optionee and pay to the applicable taxing authorities an amount equal to a percentage of this compensation income at the time of exercise. 

14.3 Disposition of Shares. The following tax consequences may apply upon disposition of the Shares. 

(a) Incentive Stock Options. If the Shares are held for more than twelve (12) months after the date of purchase of the Shares
pursuant to the exercise of an ISO and are disposed of more than two (2) years after the Date of Grant, any gain realized on disposition of the Shares will be treated as long term capital gain for federal income tax purposes. If Shares
purchased under an ISO are disposed of within the applicable one (1) year or two (2) year period, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates in the year of the
disposition) to the extent of the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price. 

(b) Nonqualified Stock Options. If the Shares are held for more than twelve (12) months after the date of purchase of the Shares
pursuant to the exercise of an NQSO, any gain realized on disposition of the Shares will be treated as long term capital gain. 
 15.
GENERAL PROVISIONS. 
 15.1 Interpretation. Any dispute regarding the interpretation of this Agreement shall
be submitted by Optionee or the Company to the Committee for review. The resolution of such a dispute by the Committee shall be final and binding on the Company and Optionee. 

15.2 Entire Agreement. The Plan, the Grant Notice and the Exercise Agreement are each incorporated herein by
reference. This Agreement, the Grant Notice, the Plan and the Exercise Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede all prior undertakings and agreements with respect to such
subject matter. 
 16. NOTICES. Any and all notices required or permitted to be given to a party pursuant to the provisions of
this Agreement will be in writing and will be effective and deemed to provide such party sufficient notice under this Agreement on the earliest of the following: (i) at the time of personal delivery, if delivery is in person; (ii) at the
time an electronic confirmation of receipt is received, if delivery is by email; (iii) at the time of transmission by facsimile, addressed to the other party at its facsimile number specified herein (or hereafter modified by subsequent notice
to the parties hereto), with confirmation of receipt made by both telephone and printed confirmation sheet verifying successful transmission of the facsimile; (iv) one (1) business day after deposit with an express overnight courier for United
States deliveries, or two (2) business days after such deposit for deliveries outside of the United States, with proof of delivery from the courier requested; or (v) three (3) business days after deposit in the United States mail by
certified mail (return receipt requested) for United States deliveries. Any notice for delivery outside the United States will be sent by email, facsimile or by express courier. Any notice not delivered personally or by email will be sent with
postage and/or other charges prepaid and properly 

  
 10 

 
addressed to Optionee at the last known address or facsimile number on the books of the Company, or at such other address or facsimile number as such other party may designate by one of the
indicated means of notice herein to the other parties hereto or, in the case of the Company, to it at its principal place of business. Notices to the Company will be marked “Attention: Chief Financial Officer.” Notices by facsimile shall
be machine verified as received. 
 17. SUCCESSORS AND ASSIGNS. The Company may assign any of its rights under this Agreement
including its rights to purchase Shares under the Right of First Refusal. This Agreement shall be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth herein, this
Agreement shall be binding upon Optionee and Optionee’s heirs, executors, administrators, legal representatives, successors and assigns. 

18. GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the internal laws of the State of
California as such laws are applied to agreements between California residents entered into and to be performed entirely within California. If any provision of this Agreement is determined by a court of law to be illegal or unenforceable, then such
provision will be enforced to the maximum extent possible and the other provisions will remain fully effective and enforceable. 
 19.
FURTHER ASSURANCES. The parties agree to execute such further documents and instruments and to take such further actions as may be reasonably necessary to carry out the purposes and intent of this Agreement. 

20. TITLES AND HEADINGS. The titles, captions and headings of this Agreement are included for ease of reference only and will be
disregarded in interpreting or construing this Agreement. Unless otherwise specifically stated, all references herein to “sections” and “exhibits” will mean “sections” and “exhibits” to this Agreement. 

21. COUNTERPARTS. This Agreement may be executed in any number of counterparts, each of which when so executed and delivered
will be deemed an original, and all of which together shall constitute one and the same agreement. 
 22. SEVERABILITY. If any
provision of this Agreement is determined by any court or arbitrator of competent jurisdiction to be invalid, illegal or unenforceable in any respect, such provision will be enforced to the maximum extent possible given the intent of the parties
hereto. If such clause or provision cannot be so enforced, such provision shall be stricken from this Agreement and the remainder of this Agreement shall be enforced as if such invalid, illegal or unenforceable clause or provision had (to the extent
not enforceable) never been contained in this Agreement. Notwithstanding the forgoing, if the value of this Agreement based upon the substantial benefit of the bargain for any party is materially impaired, which determination as made by the
presiding court or arbitrator of competent jurisdiction shall be binding, then both parties agree to substitute such provision(s) through good faith negotiations.

 AGREEMENTS,
REPRESENTATIONS AND ACKNOWLEDGMENTS OF OPTIONEE: By signing this Stock Option Exercise Notice and Agreement, Optionee hereby agrees with, and represents to, the
Company as follows: 
  

	1.	 Terms Governing. I acknowledge and agree with the Company that I am acquiring the Purchased Shares by
exercise of this Option subject to all other terms and conditions of the Notice of Stock Option Grant and the Stock Option Agreement that govern the Option, including without limitation the terms of the Company’s 2016 Equity Incentive Plan, as
it may be amended (the “Plan”). 

	2.	 Investment Intent; Securities Law Restrictions. I represent and warrant to the Company that I am
acquiring and will hold the Purchased Shares for investment for my account only, and not with a view to, or for resale in connection with, any “distribution” of the Purchased Shares within the meaning of the Securities Act of 1933, as
amended (the “Securities Act”). I understand that the Purchased Shares have not been registered under the Securities Act by reason of a specific exemption from such registration requirement and that the Purchased Shares must
be held by me indefinitely, unless they are subsequently registered under the Securities Act or I obtain an opinion of counsel (in form and substance satisfactory to the Company and its counsel) that registration is not required. I acknowledge that
the Company is under no obligation to register the Purchased Shares under the Securities Act or under any other securities law. 

  

	3.	 Restrictions on Transfer: Rule 144. I will not sell, transfer or otherwise dispose of the Purchased
Shares in violation of the Securities Act, the Securities Exchange Act of 1934, or the rules promulgated thereunder (including Rule 144 under the Securities Act described below “Rule 144”)) or of any other applicable securities laws.
I am aware of Rule 144, which permits limited public resales of securities acquired in a non-public offering, subject to satisfaction of certain conditions, which include (without limitation) that:
(a) certain current public information about the Company is available; (b) the resale occurs only after the holding period required by Rule 144 has been met; (c) the sale occurs through an unsolicited “broker’s
transaction”; and (d) the amount of securities being sold during any three-month period does not exceed specified limitations. I understand that the conditions for resale set forth in Rule 144 have not been satisfied and that the
Company has no plans to satisfy these conditions in the foreseeable future. 

  

	4.	 Access to Information; Understanding of Risk in Investment. I acknowledge that I have received and had
access to such information as I consider necessary or appropriate for deciding whether to invest in the Purchased Shares and that I had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the
issuance of the Purchased Shares. I am aware that my investment in the Company is a speculative investment that has limited liquidity and is subject to the risk of complete loss. I am able, without impairing my financial condition, to hold the
Purchased Shares for an indefinite period and to suffer a complete loss of my investment in the Purchased Shares. 

  

	5.	 Rights of First Refusal; Market Stand-off. I acknowledge that
the Purchased Shares remain subject to the Company’s Right of First Refusal and the market stand-off covenants (sometimes referred to as the “lock-up”),
all in accordance with the applicable Notice of Stock Option Grant and the Stock Option Agreement that govern the Option. 

  

	6.	 Form of Ownership. I acknowledge that the Company has encouraged me to consult my own adviser to
determine the form of ownership of the Purchased Shares that is appropriate for me. In the event that I choose to transfer my Purchased Shares to a trust, I agree to sign a Stock Transfer Agreement. In the event that I choose to transfer my
Purchased Shares to a trust that is not an eligible revocable trust, I also acknowledge that the transfer will be treated as a “disposition” for tax purposes. As a result, the favorable ISO tax treatment will be unavailable and other
unfavorable tax consequences may occur. 

  

	7.	 Investigation of Tax Consequences. I acknowledge that the Company has encouraged me to consult my own
adviser to determine the tax consequences of acquiring the Purchased Shares at this time. 

  

	8.	 Other Tax Matters. I agree that the Company does not have a duty to design or administer the Plan or its
other compensation programs in a manner that minimizes my tax liabilities. I will not make any claim against the Company or its Board, officers or employees related to tax liabilities arising from my options or my other compensation. In particular,
I acknowledge that my options (including the Option) are exempt from section 409A of the Internal Revenue Code only if the exercise price per share is at least equal to the fair market value per share of the Common Stock at the time the option
was granted by the Board. Since shares of the Common Stock are not traded on an established securities market, the determination of their fair market value was made by the Board and/or by an independent valuation firm retained by the Company. I
acknowledge that there is no guarantee in either case that the Internal Revenue Service will agree with the valuation, and I will not make any claim against the Company or its Board, officers or employees in the event that the Internal Revenue
Service asserts that the valuation was too low. 

  
 2 

	9.	 Spouse Consent. I agree to seek the consent of my spouse to the extent required by the Company to
enforce the foregoing. 

  

	10.	 Agreement to Enter into Company Co-Sale Agreement and Company
Voting Agreement. Pursuant to the Stock Option Agreement, if requested to do so by the Company, I agree to enter into and execute the then-current Company Co-Sale Agreement and/or the then-current Company
Voting Agreement concurrently with my exercise of the Option or at any other time I am requested to do so by the Company. I acknowledge that by entering into the Company Co-Sale Agreement I will be subjecting
the Purchased Shares to the rights of first refusal, co-sale rights and all the other provisions of the Company Co-Sale Agreement and that by entering into the Voting
Agreement I will be subjected to voting and other obligations and covenants regarding all Company shares I own and all other provisions of the Company Voting Agreement, in addition to the right of first refusal, repurchase option and market stand-off provisions described above. 

  

	11.	 Tax Withholding. As a condition of exercising this Option, I agree to make adequate provision for
foreign, federal, state or other tax withholding obligations, if any, which arise upon the grant, vesting or exercise of this Option, or disposition of the Purchased Shares, whether by withholding, direct payment to the Company, or otherwise.

 The undersigned hereby executes and delivers this Stock Option Exercise Notice and Agreement to agrees to be bound by its terms

BILL.COM, INC. 

2016 EQUITY INCENTIVE PLAN 

This Stock Option Agreement (this “Agreement”) is made and entered into as of the date of grant (the “Date
of Grant”) set forth on the Notice of Stock Option Grant attached as the facing page to this Agreement (the “Grant Notice”) by and between Bill.Com, Inc., a Delaware corporation (the
“Company”), and the optionee named on the Grant Notice (“Optionee”). Capitalized terms not defined in this Agreement shall have the meaning ascribed to them in the Company’s 2016 Equity Incentive
Plan, as amended from time to time (the “Plan”), or in the Grant Notice, as applicable. 
 1. GRANT
OF OPTION. The Company hereby grants to Optionee an option (this “Option”) to purchase up to the total number of shares of Common Stock of the Company, $0.00001 par value per share (the “Common
Stock”), set forth in the Grant Notice as the Shares (the “Shares”) at the Exercise Price Per Share set forth in the Grant Notice (the “Exercise Price”), subject to all of the terms and
conditions of the Grant Notice, this Agreement and the Plan. If designated as an Incentive Stock Option in the Grant Notice, this Option is intended to qualify as an incentive stock option (the “ISO”) within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), except that if on the Date of Grant Optionee is not subject to U.S. income tax, then this Option shall be a NQSO. 

2. EXERCISE PERIOD. 

2.1. Exercise Period of Option. Subject to the conditions set forth in this Agreement, all or part of this Option
may be exercised at any time after the Date of Grant. Shares purchased by exercising this Option may be subject to the Repurchase Option as set forth in Section 7 below. This Option will become vested during its term as to portions of the
Shares in accordance with the Vesting Schedule set forth in the Grant Notice. Notwithstanding any provision in the Plan or this Agreement to the contrary, on or after Optionee’s Termination Date, this Option may not be exercised with respect to
any Shares that are Unvested Shares on Optionee’s Termination Date. 
 2.2. Vesting of Option Shares. Shares
with respect to which this Option is vested at a given time pursuant to the Vesting Schedule set forth in the Grant Notice are “Vested Shares.” Shares with respect to which this Option is not vested at a given time
pursuant to the Vesting Schedule set forth in the Grant Notice are “Unvested Shares.” 
 2.3.
Expiration. The Option shall expire on the Expiration Date set forth in the Grant Notice or earlier as provided in Section 3 below. 

3. TERMINATION. 
 3.1.
Termination for Any Reason Except Death, Disability or Cause. Except as provided in subsection 3.2 in a case in which Optionee dies within three (3) months after Optionee is Terminated other than for Cause, if Optionee
is Terminated for any reason (other than Optionee’s death or Disability or for Cause), then (a) on and after Optionee’s Termination Date, this Option shall expire immediately with respect to any Shares that are Unvested Shares
and may not be exercised with respect to any Shares that are Unvested Shares on Optionee’s Termination Date and (b) this Option to the extent (and only to the extent) that it is exercisable with respect to Vested Shares on Optionee’s
Termination Date, may be exercised by Optionee no later than three (3) months after Optionee’s Termination Date (but in no event may this Option be exercised after the Expiration Date). 

 3.2. Termination Because of Death or Disability. If Optionee is
Terminated because of Optionee’s death or Disability (or if Optionee dies within three (3) months of the date of Optionee’s Termination for any reason other than for Cause), then (a) on and after Optionee’s Termination Date,
this Option shall expire immediately with respect to any Shares that are Unvested Shares and may not be exercised with respect to any Shares that are Unvested Shares on Optionee’s Termination Date and (b) this Option, to the extent (and
only to the extent) that it is exercisable with respect to Vested Shares on Optionee’s Termination Date, may be exercised by Optionee (or Optionee’s legal representative) no later than twelve (12) months after Optionee’s
Termination Date, but in no event later than the Expiration Date. Any exercise of this Option beyond (i) three (3) months after the date Optionee ceases to be an employee when Optionee’s Termination is for any reason other than
Optionee’s death or disability, within the meaning of Section 22(e)(3) of the Code; or (ii) twelve (12) months after the date Optionee ceases to be an employee when the termination is for Optionee’s disability, within the
meaning of Section 22(e)(3) of the Code, is deemed to be an NQSO. 
 3.3. Termination for Cause. If Optionee
is Terminated for Cause, then Optionee may exercise this Option, but only with respect to any Shares that are Vested Shares on Optionee’s Termination Date, and this Option shall expire on Optionee’s Termination Date, or at such
later time and on such conditions as may be affirmatively determined by the Committee. On and after Optionee’s Termination Date, this Option shall expire immediately with respect to any Shares that are Unvested Shares and may not be exercised
with respect to any Shares that are Unvested Shares on Optionee’s Termination Date. 
 3.4. No Obligation to
Employ. Nothing in the Plan or this Agreement shall confer on Optionee any right to continue in the employ of, or other relationship with, the Company or any Parent or Subsidiary of the Company, or limit in any way the right of the
Company or any Parent or Subsidiary of the Company to terminate Optionee’s employment or other relationship at any time, with or without Cause. 

4. MANNER OF EXERCISE. 

4.1. Stock Option Exercise Notice and Agreement. To exercise this Option, Optionee (or in the case of exercise
after Optionee’s death or incapacity, Optionee’s executor, administrator, heir or legatee, as the case may be) must deliver to the Company an executed Stock Option Exercise Notice and Agreement in the form attached hereto as
Annex A, or in such other form as may be approved by the Committee from time to time (the “Exercise Agreement”) and payment for the shares being purchased in accordance with this
Agreement. The Exercise Agreement shall set forth, among other things, (i) Optionee’s election to exercise this Option, (ii) the number of Shares being purchased, (iii) any representations, warranties and agreements regarding
Optionee’s investment intent and access to information as may be required by the Company to comply with applicable securities laws in connection with any exercise of this Option and (iv) any other agreements required by the Company. If
someone other than Optionee exercises this Option, then such person must submit documentation reasonably acceptable to the Company verifying that such person has the legal right to exercise this Option and such person shall be subject to all of the
restrictions contained herein as if such person were Optionee. 
 4.2. Limitations on Exercise. This Option may
not be exercised unless such exercise is in compliance with all applicable federal and state securities laws, as they are in effect on the date of exercise. 

4.3. Payment. The Exercise Agreement shall be accompanied by full payment of the Exercise Price for the shares
being purchased in cash (by check or wire transfer), or where permitted by law: 
 (a) by cancellation of indebtedness of the Company owed
to Optionee; 

  
 2 

 (b) by surrender of shares of the Company that are free and clear of all security
interests, pledges, liens, claims or encumbrances and: (i) for which the Company has received “full payment of the purchase price” within the meaning of SEC Rule 144 (and, if such shares were purchased from the Company by use of
a promissory note, such note has been fully paid with respect to such shares) or (ii) that were obtained by Optionee in the public market; 

(c) by participating in a formal cashless exercise program implemented by the Committee in connection with the Plan; 

(d) provided that a public market for the Common Stock exists, subject to compliance with applicable law, by exercising as set forth below,
through a “same day sale” commitment from Optionee and a broker-dealer whereby Optionee irrevocably elects to exercise this Option and to sell a portion of the Shares so purchased sufficient to pay the total Exercise Price, and whereby the
broker-dealer irrevocably commits upon receipt of such Shares to forward the total Exercise Price directly to the Company; or 
 (e) by any
combination of the foregoing or any other method of payment approved by the Committee that constitutes legal consideration for the issuance of Shares. 

4.4. Tax Withholding. Prior to the issuance of the Shares upon exercise of the Option, Optionee must pay or provide
for any applicable federal, state and local withholding obligations of the Company. If the Committee permits, Optionee may provide for payment of withholding taxes upon exercise of the Option by requesting that the Company retain the minimum number
of Shares with a Fair Market Value equal to the minimum amount of taxes required to be withheld; or to arrange a mandatory “sell to cover” on Participant’s behalf (without further authorization); but in no event will the Company
withhold Shares or “sell to cover” if such withholding would result in adverse accounting consequences to the Company. In case of stock withholding or a sell to cover, the Company shall issue the net number of Shares to Optionee by
deducting the Shares retained from the Shares issuable upon exercise. 
 4.5. Issuance of Shares. Provided that
the Exercise Agreement and payment are in form and substance satisfactory to counsel for the Company, the Company shall issue the Shares issuable upon a valid exercise of this Option registered in the name of Optionee, Optionee’s authorized
assignee, or Optionee’s legal representative, and shall deliver certificates representing the Shares with the appropriate legends affixed thereto. 

5. COMPLIANCE WITH LAWS AND REGULATIONS. The
Plan and this Agreement are intended to comply with Section 25102(o) and Rule 701.    Any provision of this Agreement that is inconsistent with Section 25102(o) or Rule 701 shall, without further act or amendment by the
Company or the Committee, be reformed to comply with the requirements of Section 25102(o) and/or Rule 701. The exercise of this Option and the issuance and transfer of Shares shall be subject to compliance by the Company and Optionee
with all applicable requirements of federal and state securities laws and with all applicable requirements of any stock exchange on which the Common Stock may be listed at the time of such issuance or transfer. Optionee understands that the Company
is under no obligation to register or qualify the Shares with the SEC, any state securities commission or any stock exchange to effect such compliance. 

6. NONTRANSFERABILITY OF OPTION. This Option may not be transferred in any manner
other than by will or by the laws of descent and distribution, and, with respect to NQSOs, by instrument to a testamentary trust in which the options are to be passed to beneficiaries upon the death of the trustor (settlor) or a revocable trust, or
by gift to “immediate family” as that term is defined in 17 C.F.R. 240.16a-1(e), and may be exercised during the lifetime of Optionee only by Optionee or in the event of Optionee’s incapacity,
by Optionee’s legal representative. The terms of this Option shall be binding upon the executors, administrators, successors and assigns of Optionee.

 7. COMPANY’S REPURCHASE OPTION FOR UNVESTED SHARES. If Optionee is Terminated
for any reason, or no reason, including without limitation, Optionee’s death, Disability, voluntary resignation or termination by the Company with or without Cause and Optionee has acquired Unvested Shares by exercising this Option, then the
Company and/or its assignee(s) shall have the option to repurchase all or a portion of Optionee’s Unvested Shares (as defined in Section 2.2 of this Agreement) as of the Termination Date on the terms and conditions set forth in this
Section 7 (the “Repurchase Option”). 
 7.1. Termination and Termination Date. In
case of any dispute as to whether Optionee is Terminated, the Committee shall have discretion to determine whether Optionee has been Terminated and the effective date of such Termination (the “Termination Date”). 

7.2. Exercise of Repurchase Option. Subject to the foregoing provisions of this Section, at any time within ninety
(90) days after Optionee’s Termination Date, the Company and/or its assignee(s), may elect to repurchase any or all of Optionee’s Unvested Shares by giving Optionee written notice of exercise of the Repurchase Option. 

7.3. Calculation of Repurchase Price for Unvested Shares. The Company or its assignee shall have the option to
repurchase from Optionee (or from Optionee’s personal representative as the case may be) the Unvested Shares at Optionee’s Exercise Price, as such may be proportionately adjusted for any stock split or similar change in the capital
structure of the Company as set forth in Section 2.2 of the Plan (the “Repurchase Price”). 
 7.4.
Payment of Repurchase Price. The Repurchase Price shall be payable, at the option of the Company or its assignee, by check or by cancellation of all or a portion of any outstanding indebtedness owed by Optionee to the
Company and/or such assignee, or by any combination thereof. The Repurchase Price shall be paid without interest within the term of the Repurchase Option as described in Section 7.2. 

7.5. Right of Termination Unaffected. Nothing in this Agreement shall be construed to limit or otherwise
affect in any manner whatsoever the right or power of the Company (or any Parent or Subsidiary of the Company) to terminate Optionee’s employment or other relationship with Company (or any Parent or Subsidiary of the Company) at any time, for
any reason or no reason, with or without Cause. 
 8. RESTRICTIONS ON TRANSFER. 

8.1. Disposition of Shares. Optionee hereby agrees that Optionee shall make no disposition of any of the Shares
(other than as permitted by this Agreement) unless and until: 
 (a) Optionee shall have notified the Company of the proposed disposition
and provided a written summary of the terms and conditions of the proposed disposition; 
 (b) Optionee shall have complied with all
requirements of this Agreement applicable to the disposition of the Shares; 
 (c) Optionee shall have provided the Company with written
assurances, in form and substance satisfactory to counsel for the Company, that (i) the proposed disposition does not require registration of the Shares under the Securities Act or under any applicable state securities laws or (ii) all
appropriate actions necessary for compliance with the registration requirements of the Securities Act or of any exemption from registration available under the Securities Act (including Rule 144) or applicable state securities laws have been taken;
and 

  
 4 

 (d) Optionee shall have provided the Company with written assurances, in form and substance
satisfactory to the Company, that the proposed disposition will not result in the contravention of any transfer restrictions applicable to the Shares pursuant to the provisions of the regulations promulgated under Section 25102(o), Rule 701 or
under any other applicable securities laws or adversely affect the Company’s ability to rely on the exemption(s) from registration under the Securities Act or under any other applicable securities laws for the grant of the Option, the issuance
of Shares thereunder or any other issuance of securities under the Plan. 
 8.2. Restriction on Transfer.
Optionee shall not transfer, assign, grant a lien or security interest in, pledge, hypothecate, encumber or otherwise dispose of any of the Shares which are subject to the Company’s Repurchase Option or the Right of First Refusal described
below, except as permitted by this Agreement. 
 8.3. Transferee Obligations. Each person (other than the
Company) to whom the Shares are transferred by means of one of the permitted transfers specified in this Agreement must, as a condition precedent to the validity of such transfer, acknowledge in writing to the Company that such person is bound by
the provisions of this Agreement and that the transferred Shares are subject to (i) both the Company’s Repurchase Option and the Company’s Right of First Refusal granted hereunder and (ii) the market stand-off provisions of Section 9 below, to the same extent such Shares would be so subject if retained by Optionee. 

9. MARKET STANDOFF AGREEMENT. Optionee agrees that, subject to any early release provisions that apply pro rata to stockholders
of the Company according to their holdings of Common Stock (determined on an as-converted into Common Stock basis), Optionee will not, for a period of up to one hundred eighty (180) days (plus up to an
additional thirty five (35) days to the extent reasonably requested by the Company or such underwriter(s) to accommodate regulatory restrictions on the publication or other distribution of research reports or earnings releases by the Company,
including NASD and NYSE rules) following the effective date of the registration statement filed with the SEC relating to the initial underwritten sale of Common Stock of the Company to the public under the Securities Act (the
“IPO”), directly or indirectly sell, offer to sell, grant any option for the sale of, or otherwise dispose of any Common Stock or securities convertible into Common Stock, except for: (i) transfers of
Shares permitted under Section 10.6 hereof so long as such transferee furnishes to the Company and the managing underwriter their written consent to be bound by this Section 9 as a condition precedent to such transfer; and (ii) sales
of any securities to be included in the registration statement for the IPO. For the avoidance of doubt, the provisions of this Section shall only apply to the IPO. The restricted period shall in any event terminate two (2) years after the
closing date of the IPO. In order to enforce the foregoing covenant, the Company shall have the right to place restrictive legends on the certificates representing the Shares subject to this Section and to impose stop transfer instructions with
respect to the Shares until the end of such period. Optionee further agrees to enter into any agreement reasonably required by the underwriters to implement the foregoing restrictions on transfer. For the avoidance of doubt, the foregoing provisions
of this Section shall not apply to any registration of securities of the Company (a) under an employee benefit plan or (b) in a merger, consolidation, business combination or similar transaction. 

10. COMPANY’S RIGHT OF FIRST REFUSAL. Unvested Shares may not be sold or otherwise transferred, or pledged by Optionee or made
subject to a security interest, pledge or other lien without the Company’s prior written consent, which may be withheld in the Company’s sole and absolute discretion. Before any Vested Shares held by Optionee or any transferee of such
Vested Shares (either sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including, without limitation, a transfer by gift or operation of law), the Company and/or its assignee(s) will have a
right of first refusal to purchase the Vested Shares to be sold or transferred (the “Offered Shares”) on the terms and conditions set forth in this Section (the “Right of First Refusal”). 

  
 5 

 10.1. Notice of Proposed Transfer. The Holder of the Offered
Shares will deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer the Offered Shares; (ii) the name and address of each proposed
purchaser or other transferee (the “Proposed Transferee”); (iii) the number of Offered Shares to be transferred to each Proposed Transferee; (iv) the bona fide cash price or other consideration for which the Holder
proposes to transfer the Offered Shares (the “Offered Price”); and (v) that the Holder acknowledges this Notice is an offer to sell the Offered Shares to the Company and/or its assignee(s) pursuant to the Company’s
Right of First Refusal at the Offered Price as provided for in this Agreement. 
 10.2. Exercise of Right of First
Refusal. At any time within thirty (30) days after the date of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all (or, with the consent of the Holder, less than all)
the Offered Shares proposed to be transferred to any one or more of the Proposed Transferees named in the Notice, at the purchase price, determined as specified below. 

10.3. Purchase Price. The purchase price for the Offered Shares purchased under this Section will be the Offered
Price, provided that if the Offered Price consists of no legal consideration (as, for example, in the case of a transfer by gift) then the purchase price will be the fair market value of the Offered Shares as determined in good faith
by the Committee. If the Offered Price includes consideration other than cash, then the value of the non-cash consideration, as determined in good faith by the Committee, will conclusively be deemed to be the
cash equivalent value of such non-cash consideration. 
 10.4. Payment.
Payment of the purchase price for the Offered Shares will be payable, at the option of the Company and/or its assignee(s) (as applicable), by check or by cancellation of all or a portion of any outstanding purchase money indebtedness owed by the
Holder to the Company (or to such assignee, in the case of a purchase of Offered Shares by such assignee) or by any combination thereof. The purchase price will be paid without interest within sixty (60) days after the Company’s receipt of
the Notice, or, at the option of the Company and/or its assignee(s), in the manner and at the time(s) set forth in the Notice. 
 10.5.
Holder’s Right to Transfer. If all of the Offered 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 Offered Shares to each Proposed Transferee at the Offered Price or at a higher price, provided that (i) such sale or other transfer is consummated within ninety (90) days after
the date of the Notice, (ii) any such sale or other transfer is effected in compliance with all applicable securities laws, and (iii) each Proposed Transferee agrees in writing that the provisions of this Section will continue to apply to
the Offered Shares in the hands of such Proposed Transferee. If the Offered Shares described in the Notice are not transferred to each Proposed Transferee within such ninety (90) day period, then a new Notice must be given to the Company
pursuant to which the Company will again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 

10.6. Exempt Transfers. Notwithstanding anything to the contrary in this Section, the following transfers of Vested
Shares will be exempt from the Right of First Refusal: (i) the transfer of any or all of the Vested Shares during Optionee’s lifetime by gift or on Optionee’s death by will or intestacy to any member(s) of Optionee’s
“Immediate Family” (as defined below) or to a trust for the benefit of Optionee and/or member(s) of Optionee’s Immediate Family, provided that each transferee or other recipient agrees in a writing satisfactory to the
Company that the provisions of this Section will continue to apply to the transferred Vested Shares in the hands of such transferee or other recipient; (ii) any transfer of Vested Shares made pursuant to a statutory merger, statutory
consolidation of the Company with or into another corporation or corporations or a conversion of the Company into another form of legal entity (except that the Right of First Refusal will continue to apply thereafter to such Vested Shares, in which
case the surviving corporation of such merger or consolidation or the resulting entity of such conversion shall succeed to the rights of the Company under this Section unless the agreement of merger 

  
 6 

 
or consolidation or conversion expressly otherwise provides); or (iii) any transfer of Vested Shares pursuant to the winding up and dissolution of the Company. As used herein, the term
“Immediate Family” will mean Optionee’s spouse, the lineal descendant or antecedent, father, mother, brother or sister, child, adopted child, grandchild or adopted grandchild of Optionee or Optionee’s spouse, or the
spouse of any of the above or Spousal Equivalent, as defined herein. As used herein, a person is deemed to be a “Spousal Equivalent” provided the following circumstances are true: (i) irrespective of whether or not
Optionee and the Spousal Equivalent are the same sex, they are the sole spousal equivalent of the other for the last twelve (12) months, (ii) they intend to remain so indefinitely, (iii) neither are married to anyone else, (iv) both
are at least 18 years of age and mentally competent to consent to contract, (v) they are not related by blood to a degree of closeness that which would prohibit legal marriage in the state in which they legally reside, (vi) they are
jointly responsible for each other’s common welfare and financial obligations, and (vii) they reside together in the same residence for the last twelve (12) months and intend to do so indefinitely. 

10.7. Termination of Right of First Refusal. The Right of First Refusal will terminate as to all Shares:
(i) on the effective date of the first sale of Common Stock of the Company to the general public pursuant to a registration statement filed with and declared effective by the SEC under the Securities Act (other than a registration
statement relating solely to the issuance of Common Stock pursuant to a business combination or an employee incentive or benefit plan); (ii) on any transfer or conversion of Shares made pursuant to a statutory merger or statutory consolidation of
the Company with or into another corporation or corporations if the common stock of the surviving corporation or any direct or indirect parent corporation thereof is registered under the Exchange Act; or (iii) on any transfer or
conversion of Shares made pursuant to a statutory conversion of the Company into another form of legal entity if the common equity (or comparable equity security) of entity resulting from such conversion is registered under the Exchange Act.

 10.8. Encumbrances on Vested Shares. Optionee may grant a lien or security interest in, or pledge, hypothecate
or encumber Vested Shares only if each party to whom such lien or security interest is granted, or to whom such pledge, hypothecation or other encumbrance is made, agrees in a writing satisfactory to the Company that: (i) such lien, security
interest, pledge, hypothecation or encumbrance will not adversely affect or impair the Right of First Refusal or the rights of the Company and/or its assignee(s) with respect thereto and will not apply to such Vested Shares after they are acquired
by the Company and/or its assignees under this Section; and (ii) the provisions of this Agreement will continue to apply to such Vested Shares in the hands of such party and any transferee of such party. Optionee may not grant a lien or
security interest in, or pledge, hypothecate or encumber, any Unvested Shares. 
 10.9. Effect of Company Co-Sale Agreement. If Optionee is, or at any time hereafter becomes, a party to or otherwise bound by (i) the Company’s Eighth Amended and Restated Right of First Refusal and Co-Sale Agreement dated as of February 12, 2015 among the Company and certain stockholders of the Company, as such may be amended and/or restated from time to time, and/or (ii) any other agreement that is
a successor to or replacement of such agreement (collectively, the “Company Co-Sale Agreement”), then, in the event of any conflict or inconsistency between the provisions of this
Section 10 and any provisions in the Company Co-Sale Agreement granting the Company and/or other security holders of the Company rights of first refusal and/or
co-sale rights with respect to any or all of the Shares, Optionee agrees with the Company that the terms and conditions of the Company Co-Sale Agreement shall apply,
govern, supersede and prevail over (and in lieu of) the provisions of this Section 10 so long as the Company Co-Sale Agreement is in effect and Optionee is a party to or bound thereby. If the Company Co-Sale Agreement is no longer in effect or if Optionee is not a party to or bound thereby, then the provisions of this Section 10 shall apply in full force and effect until termination of the Right of First
Refusal.

 11. RIGHTS AS A STOCKHOLDER. Optionee shall not have any of the rights of a
stockholder with respect to any Shares unless and until such Shares are issued to Optionee. Subject to the terms and conditions of this Agreement, Optionee will have all of the rights of a stockholder of the Company with respect to the Shares from
and after the date that Shares are issued to Optionee pursuant to, and in accordance with, the terms of the Exercise Agreement until such time as Optionee disposes of the Shares or the Company and/or its assignee(s) exercise(s) the Repurchase Option
or the Right of First Refusal. Upon an exercise of the Repurchase Option or the Right of First Refusal, Optionee will have no further rights as a holder of the Shares so purchased upon such exercise, other than the right to receive payment for the
Shares so purchased in accordance with the provisions of this Agreement, and Optionee will promptly surrender the stock certificate(s) evidencing the Shares so purchased to the Company for transfer or cancellation. 

12. ESCROW. As security for Optionee’s faithful performance of this Agreement, Optionee agrees, immediately upon receipt of the
stock certificate(s) evidencing the Shares, to deliver such certificate(s) to the Secretary of the Company or other designee of the Company (the “Escrow Holder”), who is hereby appointed to hold such certificate(s) and to
take all such actions and to effectuate all such transfers and/or releases of such Shares as are in accordance with the terms of this Agreement. Optionee and the Company agree that Escrow Holder will not be liable to any party to this Agreement (or
to any other party) for any actions or omissions unless Escrow Holder is grossly negligent or intentionally fraudulent in carrying out the duties of Escrow Holder under this Agreement. Escrow Holder may rely upon any letter, notice or other document
executed with any signature purported to be genuine and may rely on the advice of counsel and obey any order of any court with respect to the transactions contemplated by this Agreement and will not be liable for any act or omission taken by Escrow
Holder in good faith reliance on such documents, the advice of counsel or a court order. The Shares will be released from escrow upon termination of both the Repurchase Option and the Right of First Refusal. 

13. Company Co-Sale Agreementand Voting Agreement. As a material
inducement and consideration for the Company to enter into this Agreement, Optionee hereby agrees that if, the Company requests Optionee to enter into and become a party to (a) the Company Co-Sale
Agreement (and to subject the Shares to the rights of first refusal held by the Company and other Company investors thereunder and the co-sale rights of other investors thereunder) and/or (b) the Company
Voting Agreement (pursuant to which Optionee would agree to vote all shares of Company stock held by Optionee for the election of directors and in favor of certain material transactions (such as mergers or sales of the Company), then Optionee will
enter into such agreements and execute and deliver signature pages thereto (as requested by the Company) in such capacities as the Company requests, at the time of exercising this Option and as a condition to such exercise or at any later time. 

14. RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS. 

14.1. Legends. Optionee understands and agrees that the Company will place the legends set forth below or similar
legends on any stock certificate(s) evidencing the Shares, together with any other legends that may be required by state or U.S. Federal securities laws, the Company’s Certificate of Incorporation or Bylaws, any other agreement between Optionee
and the Company, or any agreement between Optionee and any third party (and any other legend(s) that the Company may become obligated to place on the stock certificate(s) evidencing the Shares under the terms of any agreement to which the Company is
or may become bound or obligated): 
 (a) THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE “SECURITIES ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE SECURITIES ACT
AND APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE
SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

 (b) THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON
RESALE AND TRANSFER, INCLUDING THE REPURCHASE OPTION AND RIGHT OF FIRST REFUSAL HELD BY THE ISSUER AND/OR ITS ASSIGNEE(S) AS SET FORTH IN A STOCK OPTION 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 SALE AND TRANSFER RESTRICTIONS, INCLUDING THE REPURCHASE OPTION AND RIGHT OF FIRST REFUSAL, ARE BINDING ON TRANSFEREES OF THESE SHARES. 

(c) THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A MARKET STANDOFF RESTRICTION AS SET FORTH IN A CERTAIN STOCK OPTION 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. AS A RESULT OF SUCH AGREEMENT, THESE SHARES MAY NOT BE TRADED PRIOR TO 180 DAYS (AND POSSIBLY LONGER) AFTER THE
EFFECTIVE DATE OF CERTAIN PUBLIC OFFERINGS OF THE COMMON STOCK OF THE ISSUER HEREOF. SUCH RESTRICTION IS BINDING ON TRANSFEREES OF THESE SHARES. 
 Optionee
agrees that if Optionee becomes a party to (i) the Company Co-Sale Agreement or (ii) (A) the Company’s Eighth Amended and Restated Voting Agreement dated as of February 12, 2015 among the
Company and certain stockholders of the Company, as such may be amended and/or restated from time to time, and/or (B) any other voting agreement that is a successor to or replacement of such agreement (collectively, the “Company
Voting Agreement”), then Optionee agrees that the stock certificate(s) evidencing the Shares shall, in addition, bear any legends required under the Company Co-Sale Agreement and/or the Company
Voting Agreement, as applicable. 
 14.2. Stop-Transfer Instructions. Optionee agrees that, to ensure compliance
with the restrictions imposed by this Agreement, the Company may issue appropriate “stop-transfer” instructions to its transfer agent, if any, and if the Company transfers its own securities, it may make appropriate notations to the same
effect in its own records. 
 14.3. Refusal to Transfer. The Company will 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 have been so transferred. 
 15. CERTAIN TAX CONSEQUENCES. Set forth below is a brief summary as of
the Effective Date of the Plan of some of the federal tax consequences of exercise of the Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT A
TAX ADVISER BEFORE EXERCISING THE OPTION OR DISPOSING OF THE SHARES. 
 15.1. Exercise of ISO. If the Option
qualifies as an ISO, there will be no regular federal income tax liability upon the exercise of the Option, although the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price will be treated as a tax
preference item for federal alternative minimum tax purposes and may subject Optionee to the alternative minimum tax in the year of exercise. 

  
 9 

 15.2. Exercise of Nonqualified Stock Option. If the Option does
not qualify as an ISO, there may be a regular federal income tax liability upon the exercise of the Option. Optionee will be treated as having received compensation income (taxable at ordinary income tax rates) equal to the excess, if any, of the
Fair Market Value of the Shares on the date of exercise over the Exercise Price. If Optionee is a current or former employee of the Company, the Company may be required to withhold from Optionee’s compensation or collect from Optionee and pay
to the applicable taxing authorities an amount equal to a percentage of this compensation income at the time of exercise. 
 15.3.
Disposition of Shares. The following tax consequences may apply upon disposition of the Shares. 
 (a) Incentive
Stock Options. If the Shares are held for more than twelve (12) months after the date of purchase of the Shares pursuant to the exercise of an ISO and are disposed of more than two (2) years after the Date of Grant, any gain realized
on disposition of the Shares will be treated as long term capital gain for federal income tax purposes. If Vested Shares purchased under an ISO are disposed of within the applicable one (1) year or two (2) year period, any gain realized on
such disposition will be treated as compensation income (taxable at ordinary income rates in the year of the disposition) to the extent of the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price. To
the extent the Shares were exercised prior to vesting coincident with the filing of an 83(b) Election, the amount taxed because of a disqualifying disposition will be based upon the excess, if any, of the fair market value on the date of
vesting over the exercise price. 
 (b) Nonqualified Stock Options. If the Shares are held for more than twelve
(12) months after the date of purchase of the Shares pursuant to the exercise of an NQSO, any gain realized on disposition of the Shares will be treated as long term capital gain. 

15.4. Section 83(b) Election for Unvested Shares. With respect to Unvested Shares,
which are subject to the Repurchase Option, unless an election is filed by Optionee with the Internal Revenue Service (and, if necessary, the proper state taxing authorities), within thirty (30) days of the purchase of the
Unvested Shares, electing pursuant to Section 83(b) of the Code (and similar state tax provisions, if applicable) to be taxed currently on any difference between the Exercise Price of the Unvested Shares and their Fair Market Value on the date
of purchase, there may be a recognition of taxable income (including, where applicable, alternative minimum taxable income) to Optionee, measured by the excess, if any, of the Fair Market Value of the Unvested Shares at the time they cease to be
Unvested Shares, over the Exercise Price of the Unvested Shares. 
 16. GENERAL PROVISIONS. 

16.1. Interpretation. Any dispute regarding the interpretation of this Agreement shall be submitted by Optionee or
the Company to the Committee for review. The resolution of such a dispute by the Committee shall be final and binding on the Company and Optionee. 

16.2. Entire Agreement. The Plan, the Grant Notice and the Exercise Agreement are each incorporated herein by
reference. This Agreement, the Grant Notice, the Plan and the Exercise Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede all prior undertakings and agreements with respect to such
subject matter. 
 17. NOTICES. Any and all notices required or permitted to be given to a party pursuant to the provisions of this
Agreement will be in writing and will be effective and deemed to provide such party sufficient notice under this Agreement on the earliest of the following: (i) at the time of personal delivery, if delivery is in person; (ii) at the time
an electronic confirmation of receipt is received, if delivery is by email; (iii) at the time of transmission by facsimile, addressed to the other party at its facsimile number specified herein (or hereafter modified by subsequent notice to the
parties hereto), with confirmation of receipt made by both telephone and printed confirmation sheet verifying successful transmission of the facsimile; (iv) one (1) business day after deposit with an express overnight courier for United States
deliveries, or two (2) business days after such deposit for deliveries outside of the United 

  
 10 

 
States, with proof of delivery from the courier requested; or (v) three (3) business days after deposit in the United States mail by certified mail (return receipt requested) for United
States deliveries. Any notice for delivery outside the United States will be sent by email, facsimile or by express courier. Any notice not delivered personally or by email will be sent with postage and/or other charges prepaid and properly
addressed to Optionee at the last known address or facsimile number on the books of the Company, or at such other address or facsimile number as such other party may designate by one of the indicated means of notice herein to the other parties
hereto or, in the case of the Company, to it at its principal place of business. Notices to the Company will be marked “Attention: Chief Financial Officer.” Notices by facsimile shall be machine verified as received. 

18. SUCCESSORS AND ASSIGNS. The Company may assign any of its rights under this Agreement including its rights to purchase Shares under
both the Right of First Refusal and Repurchase Option. This Agreement shall be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth herein, this Agreement shall be
binding upon Optionee and Optionee’s heirs, executors, administrators, legal representatives, successors and assigns. 
 19.
GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the internal laws of the State of California as such laws are applied to agreements between California residents entered into and to be performed entirely within
California. If any provision of this Agreement is determined by a court of law to be illegal or unenforceable, then such provision will be enforced to the maximum extent possible and the other provisions will remain fully effective and enforceable.

 20. FURTHER ASSURANCES. The parties agree to execute such further documents and instruments and to take such further
actions as may be reasonably necessary to carry out the purposes and intent of this Agreement. 
 21. TITLES AND HEADINGS.
The titles, captions and headings of this Agreement are included for ease of reference only and will be disregarded in interpreting or construing this Agreement. Unless otherwise specifically stated, all references herein to “sections”
and “exhibits” will mean “sections” and “exhibits” to this Agreement. 
 22. COUNTERPARTS.
This Agreement may be executed in any number of counterparts, each of which when so executed and delivered will be deemed an original, and all of which together shall constitute one and the same agreement. 

23. SEVERABILITY. If any provision of this Agreement is determined by any court or arbitrator of competent jurisdiction
to be invalid, illegal or unenforceable in any respect, such provision will be enforced to the maximum extent possible given the intent of the parties hereto. If such clause or provision cannot be so enforced, such provision shall be stricken from
this Agreement and the remainder of this Agreement shall be enforced as if such invalid, illegal or unenforceable clause or provision had (to the extent not enforceable) never been contained in this Agreement. Notwithstanding the forgoing, if the
value of this Agreement based upon the substantial benefit of the bargain for any party is materially impaired, which determination as made by the presiding court or arbitrator of competent jurisdiction shall be binding, then both parties agree to
substitute such provision(s) through good faith negotiations.

 AGREEMENTS,
REPRESENTATIONS AND ACKNOWLEDGMENTS OF OPTIONEE: By signing this Stock Option Exercise Notice and Agreement, Optionee hereby agrees with, and represents to, the
Company as follows: 
  

	1.	 Terms Governing. I acknowledge and agree with the Company that I am acquiring the Purchased Shares by
exercise of this Option subject to all other terms and conditions of the Notice of Stock Option Grant and the Stock Option Agreement that govern the Option, including without limitation the terms of the Company’s 2016 Equity Incentive Plan, as
it may be amended (the “Plan”). 

 EARLY EXERCISE FORM 

 

	2.	 Investment Intent; Securities Law Restrictions. I represent and warrant to the Company that I am
acquiring and will hold the Purchased Shares for investment for my account only, and not with a view to, or for resale in connection with, any “distribution” of the Purchased Shares within the meaning of the Securities Act of 1933, as
amended (the “Securities Act”). I understand that the Purchased Shares have not been registered under the Securities Act by reason of a specific exemption from such registration requirement and that the Purchased Shares must
be held by me indefinitely, unless they are subsequently registered under the Securities Act or I obtain an opinion of counsel (in form and substance satisfactory to the Company and its counsel) that registration is not required. I acknowledge that
the Company is under no obligation to register the Purchased Shares under the Securities Act or under any other securities law. 

  

	3.	 Restrictions on Transfer: Rule 144. I will not sell, transfer or otherwise dispose of the Purchased
Shares in violation of the Securities Act, the Securities Exchange Act of 1934, or the rules promulgated thereunder (including Rule 144 under the Securities Act described below “Rule 144”)) or of any other applicable securities laws.
I am aware of Rule 144, which permits limited public resales of securities acquired in a non-public offering, subject to satisfaction of certain conditions, which include (without limitation) that:
(a) certain current public information about the Company is available; (b) the resale occurs only after the holding period required by Rule 144 has been met; (c) the sale occurs through an unsolicited “broker’s
transaction;” and (d) the amount of securities being sold during any three-month period does not exceed specified limitations. I understand that the conditions for resale set forth in Rule 144 have not been satisfied and that the
Company has no plans to satisfy these conditions in the foreseeable future. 

  

	4.	 Access to Information; Understanding of Risk in Investment. I acknowledge that I have received and had
access to such information as I consider necessary or appropriate for deciding whether to invest in the Purchased Shares and that I had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the
issuance of the Purchased Shares. I am aware that my investment in the Company is a speculative investment that has limited liquidity and is subject to the risk of complete loss. I am able, without impairing my financial condition, to hold the
Purchased Shares for an indefinite period and to suffer a complete loss of my investment in the Purchased Shares. 

  

	5.	 Rights of First Refusal; Repurchase Options; Market Stand-off. I
acknowledge that the Purchased Shares remain subject to the Company’s Right of First Refusal, the Company’s Repurchase Option (with respect to unvested Purchased Shares) and the market stand-off
covenants (sometimes referred to as the “lock-up”), all in accordance with the applicable Notice of Stock Option Grant and the Stock Option Agreement that govern the Option 

 

	6.	 Form of Ownership. I acknowledge that the Company has encouraged me to consult my own adviser to
determine the form of ownership of the Purchased Shares that is appropriate for me. In the event that I choose to transfer my Purchased Shares to a trust, I agree to sign a Stock Transfer Agreement. In the event that I choose to transfer my
Purchased Shares to a trust that is not an eligible revocable trust, I also acknowledge that the transfer will be treated as a “disposition” for tax purposes. As a result, the favorable ISO tax treatment will be unavailable and other
unfavorable tax consequences may occur. 

  

	7.	 Investigation of Tax Consequences. I acknowledge that the Company has encouraged me to consult my own
adviser to determine the tax consequences of acquiring the Purchased Shares at this time. 

  

	8.	 Other Tax Matters. I agree that the Company does not have a duty to design or administer the Plan or its
other compensation programs in a manner that minimizes my tax liabilities. I will not make any claim against the Company or its Board, officers or employees related to tax liabilities arising from my options or my other compensation. In particular,
I acknowledge that my options (including the Option) are exempt from Section 409A of the Internal Revenue Code only if the exercise price per share is at least equal to the fair market value per share of the Common Stock at the time the option
was granted by the Board. Since shares of the Common Stock are not traded on an established 

  
 2 

 EARLY EXERCISE FORM 

 

	 	securities market, the determination of their fair market value was made by the Board and/or by an independent valuation firm retained by the Company. I acknowledge that there is no guarantee in either case that the
Internal Revenue Service will agree with the valuation, and I will not make any claim against the Company or its Board of Directors, officers or employees in the event that the Internal Revenue Service asserts that the valuation was too low.

  

	9.	 Spouse Consent. I agree to seek the consent of my spouse to the extent required by the Company to
enforce the foregoing. 

  

	10.	 Agreement to Enter into Company Co-Sale Agreement and Company
Voting Agreement. Pursuant to the Stock Option Agreement, if requested to do so by the Company, I agree to enter into and execute the then-current Company Co-Sale Agreement and/or the then-current Company
Voting Agreement concurrently with my exercise of the Option or at any other time I am requested to do so by the Company. I acknowledge that by entering into the Company Co-Sale Agreement I will be subjecting
the Purchased Shares to the rights of first refusal, co-sale rights and all the other provisions of the Company Co-Sale Agreement and that by entering into the Voting
Agreement I will be subjected to voting and other obligations and covenants regarding all Company shares I own and all other provisions of the Company Voting Agreement, in addition to the right of first refusal, repurchase option and market stand-off provisions described above. 

  

	11.	 Tax Withholding. As a condition of exercising this Option, I agree to make adequate provision for
foreign, federal, state or other tax withholding obligations, if any, which arise upon the grant, vesting or exercise of this Option, or disposition of the Purchased Shares, whether by withholding, direct payment to the Company, or otherwise.

 IMPORTANT NOTE: UNVESTED PURCHASED SHARES ARE SUBJECT TO REPURCHASE BY THE COMPANY. PLEASE CONSULT WITH YOUR TAX
ADVISER CONCERNING THE ADVISABILITY OF FILING AN 83(b) ELECTION WITH THE INTERNAL REVENUE SERVICE WHICH MUST BE FILED WITHIN THIRTY (30) DAYS AFTER THE PURCHASE OF SHARES TO BE EFFECTIVE.  

A form of Election under Section 83(b) is attached hereto as Exhibit 1 for reference. Unless an 83(b) election is timely filed with the
Internal Revenue Service (and, if necessary, the proper state taxing authorities), electing pursuant to Section 83(b) of the Internal Revenue Code (and similar state tax provisions, if applicable) to be taxed currently on any difference between
the purchase price of the Unvested Purchased Shares and their fair market value on the date of purchase, there may be a recognition of taxable income (including, where applicable, alternative minimum taxable income) to you, measured by the excess,
if any, of the Fair Market Value of the Unvested Purchased Shares at the time they cease to be Unvested Purchased Shares, over the purchase price of the Unvested Purchased Shares. 

Furthermore, to the extent the Purchased Shares were purchased upon exercise of an ISO, Optionee acknowledges that Optionee may be subject to federal and
state income taxes as a result of a disqualifying disposition of the Purchased Shares, with any gain realized on (a) Vested Shares initially purchased under an ISO subject to a disqualifying disposition treated as compensation income (taxable
at ordinary income rates in the year of the disposition) to the extent of the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price and (b) Unvested Shares initially purchased under an ISO (and
regardless of whether an 83(b) election is timely filed with the Internal Revenue Service) subject to a disqualifying disposition treated as compensation income (taxable at ordinary income rates in the year of the disposition) to the extent of the
excess, if any, of the Fair Market Value on the date of vesting over the Exercise Price. 
 THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND
REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THE OPTION OR DISPOSING OF THE SHARES. 
 The undersigned hereby
executes and delivers this Stock Option Exercise Notice and Agreement and agrees to be bound by its terms
