(i) Change in Ownership of the Company. A change in the ownership of the Company which occurs on the date that any one person, or

that any change in the ownership of the stock of the Company as a result of a private financing of the Company that is approved by the Board will not be considered a Change in Control; or

assets being disposed of, determined without regard to any liabilities associated with such assets. 
 For purposes of this
Section 2(f), persons will be considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the Company. 

Notwithstanding the foregoing, a transaction will not be deemed a Change in Control unless the transaction qualifies as a change in
control event within the meaning of Code Section 409A, as it has been and may be amended from time to time, and any proposed or final Treasury Regulations and Internal Revenue Service guidance that has been promulgated or may be promulgated
thereunder from time to time. 
 Further and for the avoidance of doubt, a transaction will not constitute a Change in Control
if: (i) its sole purpose is to change the jurisdiction of the Company’s incorporation, or (ii) its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the
Company’s securities immediately before such transaction.

 (n) “Employee” means any person, including officers and Directors, employed
by the Company or any Parent or Subsidiary of the Company. Neither service as a Director nor payment of a director’s fee by the Company will be sufficient to constitute “employment” by the Company.

(p) “Exchange Program” means a program under which (i) outstanding Awards are surrendered or cancelled in exchange
for Awards of the same type (which may have higher or lower exercise prices and different terms), Awards of a different type, and/or cash, (ii) Participants would have the opportunity to transfer any outstanding Awards to a financial
institution or other person or entity selected by the Administrator, and/or (iii) the exercise price of an outstanding Award is reduced or increased. The Administrator will determine the terms and conditions of any Exchange Program in its sole
discretion. 
 (q) “Fair Market Value” means, as of any date, the value of Common Stock determined as follows:

 (i) If the Common Stock is listed on any established stock exchange or a national market system, including without limitation

applicable, on the last trading date such closing sales price was reported) as quoted on such exchange or system on the day of determination, as reported in The Wall Street Journal or such other source as the Administrator deems reliable;

 (ii) If the Common Stock is regularly quoted by a recognized securities dealer but selling prices are not reported, the Fair
Market Value of a Share will be the mean between the high bid and low asked prices for the Common Stock on the day of determination (or, if no bids and asks were reported on that date, as applicable, on the last trading date such bids and asks were

Section 13 of the Plan, the maximum aggregate number of Shares that may be subject to Awards and sold under the Plan is 1,087,443 Shares, plus (i) 412,557 Shares that, as of September 1, 2010, have been reserved but not issued
pursuant to any awards granted under the RingCentral, Inc. 2003 Equity Incentive Plan (the “2003 Plan”) and are not subject to any awards granted thereunder, and (ii) any Shares subject to stock options or similar awards granted under
the 2003 Plan that expire or otherwise terminate without having been exercised in full and Shares issued pursuant to awards granted under the 2003 Plan that are forfeited to or repurchased by the Company, with the maximum number of Shares to be

 -4-

 (b) Lapsed Awards. If an Award expires or becomes unexercisable without having been
exercised in full, is surrendered pursuant to an Exchange Program, or, with respect to Restricted Stock or Restricted Stock Units, is forfeited to or repurchased by the Company due to the failure to vest, the unpurchased Shares (or for Awards other
than Options or Stock Appreciation Rights the forfeited or repurchased Shares) which were subject thereto will become available for future grant or sale under the Plan (unless the Plan has terminated). With respect to Stock Appreciation Rights, only
Shares actually issued pursuant to a Stock Appreciation Right will cease to be available under the Plan; all remaining Shares under Stock Appreciation Rights will remain available for future grant or sale under the Plan (unless the Plan has
terminated). Shares that have actually been issued under the Plan under any Award will not be returned to the Plan and will not become available for future distribution under the Plan; provided, however, that if Shares issued pursuant to Awards of
Restricted Stock or Restricted Stock Units are repurchased by the Company or are forfeited to the Company due to the failure to vest, such Shares will become available for future grant under the Plan. Shares used to pay the exercise price of an
Award or to satisfy the tax withholding obligations related to an Award will become available for future grant or sale under the Plan. To the extent an Award under the Plan is paid out in cash rather than Shares, such cash payment will not result in
reducing the number of Shares available for issuance under the Plan. Notwithstanding the foregoing and, subject to adjustment as provided in Section 13, the maximum number of Shares that may be issued upon the exercise of Incentive Stock
Options will equal the aggregate Share number stated in Section 3(a), plus, to the extent allowable under Code Section 422 and the Treasury Regulations promulgated thereunder, any Shares that become available for issuance under the Plan
pursuant to Section 3(b). 
 (c) Share Reserve. The Company, during the term of this Plan, will at all times reserve
and keep available such number of Shares as will be sufficient to satisfy the requirements of the Plan. 
 4. Administration
of the Plan. 
 (a) Procedure. 
 (i) Multiple Administrative Bodies. Different Committees with respect to different groups of Service Providers may administer the Plan. 

(ii) Other Administration. Other than as provided above, the Plan will be administered by (A) the Board or (B) a
Committee, which Committee will be constituted to satisfy Applicable Laws. 
 (b) Powers of the Administrator. Subject to
the provisions of the Plan, and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator will have the authority, in its discretion: 

(i) to determine the Fair Market Value; 

  
 -5-

 (ii) to select the Service Providers to whom Awards may be granted hereunder; 

(iii) to determine the number of Shares to be covered by each Award granted hereunder; 

(iv) to approve forms of Award Agreements for use under the Plan; 

(v) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder. Such terms and
conditions include, but are not limited to, the exercise price, the time or times when Awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or
limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator will determine; 
 (vi) to institute and determine the terms and conditions of an Exchange Program; 

(vii) to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan; 

(viii) to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of satisfying applicable foreign laws or for qualifying for favorable tax treatment under applicable foreign laws; 
 (ix) to modify or amend each Award (subject to Section 18(c) of the Plan), including but not limited to the discretionary authority to extend the post-termination exercisability period of Awards and
to extend the maximum term of an Option (subject to Section 6(d)); 
 (x) to allow Participants to satisfy withholding tax
obligations in a manner prescribed in Section 14; 
 (xi) to authorize any person to execute on behalf of the Company any
instrument required to effect the grant of an Award previously granted by the Administrator; 
 (xii) to allow a Participant to
defer the receipt of the payment of cash or the delivery of Shares that otherwise would be due to such Participant under an Award; and 
 (xiii) to make all other determinations deemed necessary or advisable for administering the Plan. 
 (c) Effect of Administrator’s Decision. The Administrator’s decisions, determinations and interpretations will be final and binding on all Participants and any other holders of
Awards. 
 5. Eligibility. Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock, and Restricted Stock
Units may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. 

  
 -6-

 6. Stock Options. 

(a) Grant of Options. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to time, may
grant Options in such amounts as the Administrator, in its sole discretion, will determine. 
 (b) Option Agreement. Each
Award of an Option will be evidenced by an Award Agreement that will specify the exercise price, the term of the Option, the number of Shares subject to the Option, the exercise restrictions, if any, applicable to the Option, and such other terms
and conditions as the Administrator, in its sole discretion, will determine. 
 (c) Limitations. Each Option will be
designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. Notwithstanding such designation, however, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock
Options are exercisable for the first time by the Participant during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds one hundred thousand dollars ($100,000), such Options will be treated as Nonstatutory Stock
Options. For purposes of this Section 6(c), Incentive Stock Options will be taken into account in the order in which they were granted, the Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares
is granted, and calculation will be performed in accordance with Code Section 422 and Treasury Regulations promulgated thereunder. 
 (d) Term of Option. The term of each Option will be stated in the Award Agreement; provided, however, that the term will be no more than ten (10) years from the date of grant thereof. In the
case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or
any Parent or Subsidiary, the term of the Incentive Stock Option will be five (5) years from the date of grant or such shorter term as may be provided in the Award Agreement. 

(e) Option Exercise Price and Consideration. 
 (i) Exercise Price. The per Share exercise price for the Shares to be issued pursuant to the exercise of an Option will be determined by the Administrator, but will be no less than one hundred
percent (100%) of the Fair Market Value per Share on the date of grant. In addition, in the case of an Incentive Stock Option granted to an Employee who owns stock representing more than ten percent (10%) of the voting power of all classes
of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than one hundred ten percent (110%) of the Fair Market Value per Share on the date of grant. Notwithstanding the foregoing provisions of this
Section 6(e)(i), Options may be granted with a per Share exercise price of less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent
with, Code Section 424(a). 
 (ii) Waiting Period and Exercise Dates. At the time an Option is granted, the
Administrator will fix the period within which the Option may be exercised and will determine any conditions that must be satisfied before the Option may be exercised. 

  
 -7-

 (iii) Form of Consideration. The Administrator will determine the acceptable form of
consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable form of consideration at the time of grant. Such consideration may consist entirely
of: (1) cash; (2) check; (3) promissory note, to the extent permitted by Applicable Laws, (4) other Shares, provided that such Shares have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the
Shares as to which such Option will be exercised and provided further that accepting such Shares will not result in any adverse accounting consequences to the Company, as the Administrator determines in its sole discretion; (5) consideration
received by the Company under cashless exercise program (whether through a broker or otherwise) implemented by the Company in connection with the Plan; (6) by net exercise, (7) such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws, or (8) any combination of the foregoing methods of payment. In making its determination as to the type of consideration to accept, the Administrator will consider if acceptance of
such consideration may be reasonably expected to benefit the Company. 
 (f) Exercise of Option. 

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms of
the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. 

An Option will be deemed exercised when the Company receives: (i) notice of exercise (in such form as the Administrator may specify
from time to time) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with applicable tax withholding). Full payment may consist of any consideration and
method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the name of the
Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a
stockholder will exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a
dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 13 of the Plan. 
 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. 
 (ii) Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider,
other than upon the Participant’s termination as the result of the Participant’s death or Disability, the Participant may exercise his or her Option within thirty (30) days of termination, or such longer period of time as is specified
in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement) to the extent that the Option is vested on the date of termination. Unless otherwise provided by the

  
 -8-

 
Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If
after termination the Participant does not exercise his or her Option within the time specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

(iii) Disability of Participant. If a Participant ceases to be a Service Provider as a result of the Participant’s
Disability, the Participant may exercise his or her Option within six (6) months of termination, or such longer period of time as is specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set
forth in the Award Agreement) to the extent the Option is vested on the date of termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares
covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will
revert to the Plan. 
 (iv) Death of Participant. If a Participant dies while a Service Provider, the Option may be
exercised within six (6) months following the Participant’s death, or within such longer period of time as is specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award
Agreement) to the extent that the Option is vested on the date of death, by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to the Participant’s death in a form acceptable to the Administrator.
If no such beneficiary has been designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s
will or in accordance with the laws of descent and distribution. Unless otherwise provided by the Administrator, if at the time of death Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the
Option will immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

7. Stock Appreciation Rights. 
 (a) Grant of Stock Appreciation Rights. Subject to the terms and conditions of the Plan, a Stock Appreciation Right may be granted to Service Providers at any time and from time to time as will be
determined by the Administrator, in its sole discretion. 
 (b) Number of Shares. The Administrator will have complete
discretion to determine the number of Shares subject to any Award of Stock Appreciation Rights. 
 (c) Exercise Price and
Other Terms. The per Share exercise price for the Shares that will determine the amount of the payment to be received upon exercise of a Stock Appreciation Right as set forth in Section 7(f) will be determined by the Administrator and will
be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. Otherwise, the Administrator, subject to the provisions of the Plan, will have complete discretion to determine the terms and conditions of
Stock Appreciation Rights granted under the Plan. 

  
 -9-

 (d) Stock Appreciation Right Agreement. Each Stock Appreciation Right grant will be
evidenced by an Award Agreement that will specify the exercise price, the term of the Stock Appreciation Right, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine. 

(e) Expiration of Stock Appreciation Rights. A Stock Appreciation Right granted under the Plan will expire upon the date
determined by the Administrator, in its sole discretion, and set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Section 6(d) relating to the maximum term and Section 6(f) relating to exercise also will apply to
Stock Appreciation Rights. 
 (f) Payment of Stock Appreciation Right Amount. Upon exercise of a Stock Appreciation
Right, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying: 
 (i) The
difference between the Fair Market Value of a Share on the date of exercise over the exercise price; times 
 (ii) The number
of Shares with respect to which the Stock Appreciation Right is exercised. 
 At the discretion of the Administrator, the
payment upon Stock Appreciation Right exercise may be in cash, in Shares of equivalent value, or in some combination thereof. 

8. Restricted Stock. 
 (a) Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to time, may grant Shares of Restricted Stock to Service Providers in
such amounts as the Administrator, in its sole discretion, will determine. 
 (b) Restricted Stock Agreement. Each Award
of Restricted Stock will be evidenced by an Award Agreement that will specify the Period of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the
Administrator determines otherwise, the Company as escrow agent will hold Shares of Restricted Stock until the restrictions on such Shares have lapsed. 
 (c) Transferability. Except as provided in this Section 8 or as the Administrator determines, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated
or hypothecated until the end of the applicable Period of Restriction. 
 (d) Other Restrictions. The Administrator, in
its sole discretion, may impose such other restrictions on Shares of Restricted Stock as it may deem advisable or appropriate. 

(e) Removal of Restrictions. Except as otherwise provided in this Section 8, Shares of Restricted Stock covered by each
Restricted Stock grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction or at such other time as the Administrator may determine. The Administrator, in its discretion, may
accelerate the time at which any restrictions will lapse or be removed. 

  
 -10-

 (f) Voting Rights. During the Period of Restriction, Service Providers holding Shares
of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise. 
 (g) Dividends and Other Distributions. During the Period of Restriction, Service Providers holding Shares of Restricted Stock will be entitled to receive all dividends and other distributions paid
with respect to such Shares, unless the Administrator provides otherwise. 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. 
 (h) Return of Restricted Stock to Company. On the date set
forth in the Award Agreement, the Restricted Stock for which restrictions have not lapsed will revert to the Company and again will become available for grant under the Plan. 
 9. Restricted Stock Units. 
 (a) Grant. Restricted Stock Units may be
granted at any time and from time to time as determined by the Administrator. After the Administrator determines that it will grant Restricted Stock Units, it will advise the Participant in an Award Agreement of the terms, conditions, and
restrictions related to the grant, including the number of Restricted Stock Units. 
 (b) Vesting Criteria and Other
Terms. The Administrator will set vesting criteria in its discretion, which, depending on the extent to which the criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. The Administrator
may set vesting criteria based upon the achievement of Company-wide, business unit, or individual goals (including, but not limited to, continued employment or service), or any other basis determined by the Administrator in its discretion.

 (c) Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant will be entitled to
receive a payout as determined by the Administrator. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be met to
receive a payout. 
 (d) Form and Timing of Payment. Payment of earned Restricted Stock Units will be made as soon as
practicable after the date(s) determined by the Administrator and set forth in the Award Agreement. The Administrator, in its sole discretion, may settle earned Restricted Stock Units in cash, Shares, or a combination of both. 

(e) Cancellation. On the date set forth in the Award Agreement, all unearned Restricted Stock Units will be forfeited to the
Company. 
 10. Compliance With Code Section 409A. Awards will be designed and operated in such a manner that they
are either exempt from the application of, or comply with, the requirements of Code Section 409A, except as otherwise determined in the sole discretion of the Administrator. The Plan and each Award Agreement under the Plan is intended to meet
the requirements of Code Section 409A and will be construed and interpreted in accordance with such intent, except as 

  
 -11-

 
otherwise determined in the sole discretion of the Administrator. To the extent that an Award or payment, or the settlement or deferral thereof, is subject to Code Section 409A the Award
will be granted, paid, settled or deferred in a manner that will meet the requirements of Code Section 409A, such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code
Section 409A. 
 11. Leaves of Absence/Transfer Between Locations. Unless the Administrator
provides otherwise, vesting of Awards granted hereunder will be suspended during any unpaid leave of absence. A Participant will not cease to be an Employee in the case of (i) any leave of absence approved by the Company or (ii) transfers
between locations of the Company or between the Company, its Parent, or any Subsidiary. For purposes of Incentive Stock Options, no such leave may exceed three (3) months, unless reemployment upon expiration of such leave is guaranteed by
statute or contract. If reemployment upon expiration of a leave of absence approved by the Company is not so guaranteed, then six (6) months following the first (1st) day of such leave, any Incentive Stock Option held by the Participant will cease to be treated as an Incentive
Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option. 
 12. Limited Transferability of
Awards. 
 (a) Unless determined otherwise by the Administrator, Awards may not be sold, pledged, assigned, hypothecated, or
otherwise transferred in any manner other than by will or by the laws of descent and distribution, and may be exercised, during the lifetime of the Participant, only by the Participant. If the Administrator makes an Award transferable, such Award
may only be transferred (i) by will, (ii) by the laws of descent and distribution, or (iii) as permitted by Rule 701 of the Securities Act of 1933, as amended (the “Securities Act”). 

(b) Further, until the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, or after
the Administrator determines that it is, will, or may no longer be relying upon the exemption from registration under the Exchange Act as set forth in Rule 12h-1(f) promulgated under the Exchange Act, an Option, or prior to exercise, the Shares
subject to the Option, may not be pledged, hypothecated or otherwise transferred or disposed of, in any manner, including by entering into any short position, any “put equivalent position” or any “call equivalent position” (as
defined in Rule 16a-1(h) and Rule 16a-1(b) of the Exchange Act, respectively), other than to (i) persons who are “family members” (as defined in Rule 701(c)(3) of the Securities Act) through gifts or domestic relations orders, or
(ii) to an executor or guardian of the Participant upon the death or disability of the Participant. Notwithstanding the foregoing sentence, the Administrator, in its sole discretion, may determine to permit transfers to the Company or in
connection with a Change in Control or other acquisition transactions involving the Company to the extent permitted by Rule 12h-1(f). 
 13. Adjustments; Dissolution or Liquidation; Merger or Change in Control. 

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or
other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate
structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or

enlargement of the benefits or potential benefits intended to be made available under the Plan, will adjust the number and class of Shares that may be delivered under the Plan and/or the number,
class, and price of Shares covered by each outstanding Award; provided, however, that the Administrator will make such adjustments to an Award required by Section 25102(o) of the California Corporations Code to the extent the Company is relying
upon the exemption afforded thereby with respect to the Award. 
 (b) Dissolution or Liquidation. In the event of the
proposed dissolution or liquidation of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will
terminate immediately prior to the consummation of such proposed action. 
 (c) Merger or Change in Control. In the event
of a merger or Change in Control, each outstanding Award will be treated as the Administrator determines (subject to the provisions of the proceeding paragraph) without a Participant’s consent, including, without limitation, that
(i) Awards will be assumed, or substantially equivalent Awards will be substituted, by the acquiring or succeeding corporation (or an affiliate thereof) with appropriate adjustments as to the number and kind of shares and prices; (ii) upon
written notice to a Participant, that the Participant’s Awards will terminate upon or immediately prior to the consummation of such merger or Change in Control; (iii) outstanding Awards will vest and become exercisable, realizable, or
payable, or restrictions applicable to an Award will lapse, in whole or in part prior to or upon consummation of such merger or Change in Control, and, to the extent the Administrator determines, terminate upon or immediately prior to the
effectiveness of such merger or Change in Control; (iv) (A) the termination of an Award in exchange for an amount of cash and/or property, if any, equal to the amount that would have been attained upon the exercise of such Award or
realization of the Participant’s rights as of the date of the occurrence of the transaction (and, for the avoidance of doubt, if as of the date of the occurrence of the transaction the Administrator determines in good faith that no amount would
have been attained upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company without payment), or (B) the replacement of such Award with other rights or property selected
by the Administrator in its sole discretion; or (v) any combination of the foregoing. In taking any of the actions permitted under this subsection 13(c), the Administrator will not be obligated to treat all Awards, all Awards held by a
Participant, or all Awards of the same type, similarly. 
 In the event that the successor corporation does not assume or
substitute for the Award (or portion thereof), the Participant will fully vest in and have the right to exercise all of his or her outstanding Options and Stock Appreciation Rights, including Shares as to which such Awards would not otherwise be
vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting, all performance goals or other vesting criteria will be deemed achieved at one hundred
percent (100%) of target levels and all other terms and conditions met. In addition, if an Option or Stock Appreciation Right is not assumed or substituted in the event of a merger or Change in Control, the Administrator will notify the
Participant in writing or electronically that the Option or Stock Appreciation Right will be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option or Stock Appreciation Right will terminate upon the
expiration of such period. 

  
 -13-

 For the purposes of this subsection 13(c), an Award will be considered assumed if, following
the merger or Change in Control, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the merger or Change in Control, the consideration (whether stock, cash, or other securities or property)
received in the merger or Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority
of the outstanding Shares); provided, however, that if such consideration received in the merger or Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor
corporation, provide for the consideration to be received upon the exercise of 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 merger or Change in Control. 
 Notwithstanding anything in this Section 13(c) to the contrary, an Award that vests, is earned or paid-out upon the satisfaction of one or more performance goals will not be considered assumed if the
Company or its successor modifies any of such performance goals without the Participant’s consent; provided, however, a modification to such performance goals only to reflect the successor corporation’s post-Change in Control corporate
structure will not be deemed to invalidate an otherwise valid Award assumption. 
 Notwithstanding anything in this
Section 13(c) to the contrary, if a payment under an Award Agreement is subject to Code Section 409A and if the change in control definition contained in the Award Agreement does not comply with the definition of “change of
control” for purposes of a distribution under Code Section 409A, then any payment of an amount that is otherwise accelerated under this Section will be delayed until the earliest time that such payment would be permissible under Code
Section 409A without triggering any penalties applicable under Code Section 409A. 
 14. Tax Withholding.

 (a) Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof),
the Company will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, local, foreign or other taxes (including the Participant’s FICA obligation)
required to be withheld with respect to such Award (or exercise thereof). 
 (b) Withholding Arrangements. The
Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation) (i) paying cash,
(ii) electing to have the Company withhold otherwise deliverable Shares having a Fair Market Value equal to the minimum statutory amount required to be withheld, (iii) delivering to the Company already-owned Shares having a Fair Market
Value equal to the statutory amount required to be withheld, provided the delivery of such Shares will not result in any adverse accounting consequences, as the Administrator determines in its sole discretion, or (iv) selling a sufficient
number of Shares otherwise deliverable to the Participant through such means as the Administrator may determine in its sole discretion (whether through a broker or otherwise) equal to the amount

  
 -14-

 
required to be withheld. The amount of the withholding requirement will be deemed to include any amount which the Administrator agrees may be withheld at the time the election is made, not to
exceed the amount determined by using the maximum federal, state or local marginal income tax rates applicable to the Participant with respect to the Award on the date that the amount of tax to be withheld is to be determined. The Fair Market Value
of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld. 
 15.
No Effect on Employment or Service. Neither the Plan nor any Award will confer upon a Participant any right with respect to continuing the Participant’s relationship as a Service Provider with the Company, nor will they interfere in any
way with the Participant’s right or the Company’s right to terminate such relationship at any time, with or without cause, to the extent permitted by Applicable Laws. 

16. Date of Grant. The date of grant of an Award will be, for all purposes, the date on which the Administrator makes the
determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each Participant within a reasonable time after the date of such grant. 

17. Term of Plan. Subject to Section 21 of the Plan, the Plan will become effective upon its adoption by the Board. Unless
sooner terminated under Section 18, it will continue in effect for a term of ten (10) years from the later of (a) the effective date of the Plan, or (b) the earlier of the most recent Board or stockholder approval of an increase
in the number of Shares reserved for issuance under the Plan. 
 18. Amendment and Termination of the Plan. 

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan. 

(b) Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent necessary and desirable
to comply with Applicable Laws. 
 (c) Effect of Amendment or Termination. No amendment, alteration, suspension or
termination of the Plan will impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company. Termination of the
Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. 

19. Conditions Upon Issuance of Shares. 
 (a) Legal Compliance. Shares will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance and delivery of such Shares will comply with Applicable Laws
and will be further subject to the approval of counsel for the Company with respect to such compliance. 

  
 -15-

 (b) Investment Representations. As a condition to the exercise of an Award, the
Company may require the person exercising such Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required. 
 20. Inability to Obtain Authority. The
inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, will relieve the Company of
any liability in respect of the failure to issue or sell such Shares as to which such requisite authority will not have been obtained. 
 21. Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted by the Board. Such stockholder
approval will be obtained in the manner and to the degree required under Applicable Laws. 
 22. Information to
Participants. Beginning on the earlier of (i) the date that the aggregate number of Participants under this Plan is five hundred (500) or more and the Company is relying on the exemption provided by Rule 12h-1(f)(1) under the Exchange
Act and (ii) the date that the Company is required to deliver information to Participants pursuant to Rule 701 under the Securities Act, and until such time as the Company becomes subject to the reporting requirements of Section 13 or
15(d) of the Exchange Act, is no longer relying on the exemption provided by Rule 12h-1(f)(1) under the Exchange Act or is no longer required to deliver information to Participants pursuant to Rule 701 under the Securities Act, the Company shall
provide to each Participant the information described in paragraphs (e)(3), (4), and (5) of Rule 701 under the Securities Act not less frequently than every six (6) months with the financial statements being not more than 180 days old and
with such information provided either by physical or electronic delivery to the Participants or by written notice to the Participants of the availability of the information on an Internet site that may be password-protected and of any password
needed to access the information. The Company may request that Participants agree to keep the information to be provided pursuant to this section confidential. If a Participant does not agree to keep the information to be provided pursuant to this
section confidential, then the Company will not be required to provide the information unless otherwise required pursuant to Rule 12h-1(f)(1) under the Exchange Act or Rule 701 of the Securities Act.

 Vesting Schedule: 
 This Option shall be exercisable, in whole or in part, according to the following vesting schedule: 
 Twenty-five percent (25%) of the Shares subject to the Option shall vest on the one (1) year anniversary of the Vesting Commencement Date, and one forty-eighth (1/48th) of the Shares subject to the Option shall vest each month
thereafter on the same day of the month as the Vesting Commencement Date (and if there is no corresponding day, on the last day of the month), subject to Participant continuing to be a Service Provider through each such date; furthermore:

 Double-Trigger Equity Award Vesting Acceleration. If the Company consummates a “Change in Control” (as
defined below) and (a) Participant is terminated by the Company for reasons other than “Cause” (as defined below), death or disability, within sixty (60) days prior to the Change in Control and/or is not hired by the
surviving/successor entity, or (b) within twelve (12) months after the Change in Control, the Participant’s employment is terminated by the successor/surviving company for reasons other than “Cause” (as defined below), death
or disability, or (c) if the Participant’s employment with the successor/surviving Company is terminated by the Participant for “Good Reason” (as defined below), then, provided that Participant signs and does not revoke a release
of all claims against the Company, fifty percent (50%) of the Participant’s then unvested Shares subject to the Option shall immediately vest in full on the Participant’s termination date and be exercisable within ninety
(90) days of the Participant’s termination date. 

  
 -1-

	 	•	 	 “Change of Control” means the occurrence of any of the following events: (A) any colidation or merger of the Company with or into any
other corporation or other entity or person, or any other corporate reorganization after which the stockholders of the Company immediately prior to such colidation, merger or reorganization, fail to own at least 50% of the voting power of the
surviving entity immediately following such colidation, merger or reorganization, (B) any transaction or series of related transactions to which the Company is a party in which in excess of fifty percent (50%) of the Company’s voting
power is transferred, but excluding in the case of (A) and (B), (x) any colidation or merger effected exclusively to change the domicile or state of incorporation of the Company, or (y) any transaction or series of transactions
principally for bona fide equity financing purposes in which cash is received by the Company or indebtedness of the Company is cancelled or converted or a combination thereof, or (C) a sale, lease or other disposition of all or substantially
all of the assets of the Company. 

  

	 	•	 	 “Cause” means that the Participant (i) commits fraud, misappropriation, embezzlement or breach of fiduciary duty, (ii) materially
breaches or repeatedly fails to perform the Participant’s employment duties to the Company, (iii) breaches the Participant’s Confidentiality Agreement or any other similar agreement between the Participant and the Company,
(iv) is found guilty of any criminal act or otherwise commits any act which, in the reasonable discretion of the Company, deems the Participant unfit or unable to continue serving as a Service Provider or (v) is deemed incapacitated in the
reasonable discretion of the Company. 

  

	 	•	 	 A resignation for “Good Reason” means that the Participant resigns from all positions the Participant then holds with the Company and its
affiliates (or the acquirer) and at least one of the following events occurs without the consent of the Participant: (i) a material diminution of at least five percent (5%) in the Participant’s overall compensation (it being agreed
that Participant’s failure to achieve or be paid any target bonus does not constitute a 5% reduction of Participant’s overall compensation), (ii) a material diminution in the Participant’s authority,

  
 -2-

	 	responsibilities, or duties (except that a change in job position or title, without more, shall not be a material diminution), or a material diminution in the authority,
responsibilities, or duties of the supervisor to whom Participant reports either immediately prior to or after the Change of Control, (iii) the Company or acquirer’s requirement that the Participant relocate the Participant’s primary
work location to a location that would increase the Participant’s one-way commute distance by more than thirty (30) miles (than Participant’s current commute distance to the Company’s then-current corporate offices). For
Good Reason to be established, the Participant must provide written notice to the Company’s General Counsel within ninety (90) days immediately following such event, the Company must fail to remedy such event within thirty (30) days
after receipt of such notice, and the Participant’s resignation must be effective not later than ninety (90) days after the expiration of such cure period. For purposes of notice, if a “diminution” occurs incrementally over a
period of time (not to exceed twelve (12) months from the date of the Change in Control), the “event” shall not be deemed to occur at the end of such diminution period. 

Termination Period: 

This Option shall be exercisable for 90 (ninety) days after Participant ceases to be a Service Provider, unless such termination is due to
Participant’s death or Disability, in which case this Option shall be exercisable for 6 (six) months after Participant ceases to be a Service Provider. Notwithstanding the foregoing sentence, in no event may this Option be exercised after the
Term/Expiration Date as provided above and this Option may be subject to earlier termination as provided in Section 13 of the Plan. 
  

	II.	AGREEMENT 

 1.
Grant of Option. The Administrator of the Company hereby grants to the Participant named in the Notice of Stock Option Grant in Part I of this Agreement (“Participant”), an option (the “Option”) to purchase the number of
Shares set forth in the Notice of Stock Option Grant, at the exercise price per Share set forth in the Notice of Stock Option Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan, which is incorporated herein
by reference. Subject to Section 18 of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall prevail. 

If designated in the Notice of Stock Option Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as
an Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the $100,000 rule of Code Section 422(d), this Option shall be treated as a Nonstatutory Stock Option (“”). Further, if
for any reason this Option (or portion thereof) shall not qualify as an ISO, then, to the extent of such nonqualification, such Option (or portion thereof) shall be regarded as a granted under the Plan. In no event shall the Administrator, the
Company or any Parent or Subsidiary or any of their respective employees or directors have any liability to Participant (or any other person) due to the failure of the Option to qualify for any reason as an ISO. 

  
 -3-

 2. Exercise of Option. This Option shall be exercisable during its term in accordance
with the provisions of Section 6 of the Plan as follows: 
 (a) Right to Exercise. 

(i) Subject to subsections 2(a)(ii) and 2(a)(iii) below, this Option shall be exercisable cumulatively according to the Vesting
Schedule set forth in the Notice of Stock Option Grant. Alternatively, at the election of Participant, this Option may be exercised in whole or in part at any time as to Shares that have not yet vested. Vested Shares shall not be subject to the
Company’s Repurchase Option (as set forth and defined in the Restricted Stock Purchase Agreement, attached hereto as Exhibit C-1). 
 (ii) As a condition to exercising this Option for unvested Shares, Participant shall execute the Restricted Stock Purchase Agreement. 

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

(iv) All exercised Shares shall be subject to the Company’s Right of First Refusal (as set forth and defined in the Exercise
Notice, attached hereto as Exhibit A). 
 (b) Method of Exercise. This Option shall be exercisable by delivery of
an exercise notice in the form attached as Exhibit A (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which shall state the election to exercise the Option, the number of
Shares with respect to which the Option is being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of the aggregate
Exercise Price as to all Exercised Shares, together with any applicable tax withholding. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price,
together with any applicable tax withholding. 
 No Shares shall be issued pursuant to the exercise of an Option unless such
issuance and such exercise comply with Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to Participant on the date on which the Option is exercised with respect to such Shares. 

3. Participant’s Representations. In the event the Shares have not been registered under the Securities Act of 1933, as
amended (the “Securities Act”), at the time this Option is exercised, Participant shall, if required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment
Representation Statement in the form attached hereto as Exhibit B. 
 4. Lock-Up Period. Participant hereby
agrees that Participant shall not offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of,
directly or indirectly, any Common Stock (or other securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or
other securities) of the Company held by Participant (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred and
eighty (180) days following the effective date of any registration statement of the Company filed under the Securities Act (or such other period as may be requested by the Company or the 

  
 -4-

 
underwriters to accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not
limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto). 
 Participant agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter which are consistent with the foregoing or which are necessary to give
further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, Participant shall provide, within ten (10) days of such request, such information
as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in this
Section 4 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a Commission Rule 145 transaction on Form
S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred and
eighty (180) day (or other) period. Participant agrees that any transferee of the Option or shares acquired pursuant to the Option shall be bound by this Section 4. 
 5. Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the election of the Participant: 

(a) cash; 
 (b)
check; 
 (c) consideration received by the Company under a formal cashless exercise program adopted by the Company in
connection with the Plan; or 
 (d) surrender of other Shares which (i) shall be valued at its Fair Market Value on the
date of exercise, and (ii) must be owned free and clear of any liens, claims, encumbrances or security interests, if accepting such Shares, in the sole discretion of the Administrator, shall not result in any adverse accounting consequences to
the Company. 
 6. Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been
approved by the stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any Applicable Law. 

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

  
 -5-

 (b) Further, until the Company becomes subject to the reporting requirements of
Section 13 or 15(d) of the Exchange Act, or after the Administrator determines that it is, will, or may no longer be relying upon the exemption from registration of Options under the Exchange Act as set forth in Rule 12h-1(f) promulgated under
the Exchange Act (the “Reliance End Date”), Participant shall not transfer this Option or, prior to exercise, the Shares subject to this Option, in any manner other than (i) to persons who are “family members” (as defined in
Rule 701(c)(3) of the Securities Act) through gifts or domestic relations orders, or (ii) to an executor or guardian of Participant upon the death or disability of Participant. Until the Reliance End Date, the Options and, prior to exercise,
the Shares subject to this Option, may not be pledged, hypothecated or otherwise transferred or disposed of, including by entering into any short position, any “put equivalent position” or any “call equivalent position” (as
defined in Rule 16a-1(h) and Rule 16a-1(b) of the Exchange Act, respectively), other than as permitted in clauses (i) and (ii) of this paragraph. 
 8. Term of Option. This Option may be exercised only within the term set out in the Notice of Stock Option Grant, and may be exercised during such term only in accordance with the Plan and the
terms of this Option Agreement. 
 9. Tax Obligations. 

(a) Tax Withholding. Participant agrees to make appropriate arrangements with the Company (or the Parent or Subsidiary employing or
retaining Participant) for the satisfaction of all Federal, state, local and foreign income and employment tax withholding requirements applicable to the Option exercise. Participant acknowledges and agrees that the Company may refuse to honor the
exercise and refuse to deliver the Shares if such withholding amounts are not delivered at the time of exercise. 
 (b)
Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Participant herein 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, or (ii) the date one (1) year after the date of exercise, 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. 
 (c) Code
Section 409A. Under Code Section 409A, an Option that vests after December 31, 2004 (or that vested on or prior to such date but which was materially modified after October 3, 2004) that was granted with a per Share exercise
price that is determined by the Internal Revenue Service (the “IRS”) to be less than the Fair Market Value of a Share on the date of grant (a “discount option”) may be considered “deferred compensation.” An Option that
is a “discount option” may result in (i) income recognition by Participant prior to the exercise of the Option, (ii) an additional twenty percent (20%) federal income tax, and (iii) potential penalty and interest
charges. The “discount option” may also result in additional state income, penalty and interest tax to the Participant. Participant acknowledges that the Company cannot and has not guaranteed that the IRS will agree that the per Share
exercise price of this Option equals or exceeds the Fair Market Value of a Share on the date of grant in a later examination. Participant agrees that if the IRS determines that the Option was granted with a per Share exercise price that was less
than the Fair Market Value of a Share on the date of grant, Participant shall be solely responsible for Participant’s costs related to such a determination. 

  
 -6-

 10. Entire Agreement; Governing Law. The Plan is incorporated herein by reference.
The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the
subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant. This Option Agreement is governed by the internal substantive laws but not the choice of
law rules of California. 
 11. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING
OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED
THIS OPTION OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF
CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING
PARTICIPANT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 

  
 -7-

 Participant acknowledges receipt of a copy of the Plan and represents that he or she is
familiar with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Participant has reviewed the Plan and this Option in their entirety, has had an opportunity to obtain the advice of

2010 EQUITY INCENTIVE PLAN 
 EXERCISE NOTICE 
 RingCentral, Inc. 

1400 Fashion Island Blvd., 7th Floor 
 San
Mateo, CA 94404 
 Attention: Legal Department 
 1. Exercise of Option. Effective as of today,             ,         , the undersigned
(“Participant”) hereby elects to exercise Participant’s option (the “Option”) to purchase                  shares of the Common Stock (the
“Shares”) of RingCentral, Inc. (the “Company”) under and pursuant to the 2010 Equity Incentive Plan (the “Plan”) and the Stock Option Agreement – Early Exercise & Acceleration dated
            ,          (the “Option Agreement”). 
 2. Delivery of Payment. Participant herewith delivers to the Company the full purchase price of the Shares, as set forth in the Option Agreement, and any and all withholding taxes due in connection
with the exercise of the Option. 
 3. Representations of Participant. Participant acknowledges that Participant has
received, read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms and conditions. 
 4. Rights as Stockholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to
vote or receive dividends or any other rights as a stockholder shall exist with respect to the Common Stock subject to an Award, notwithstanding the exercise of the Option. The Shares shall be issued to Participant as soon as practicable after the
Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for which the record date is prior to the date of issuance except as provided in Section 13 of the Plan. 

5. Company’s Right of First Refusal. Before any Shares held by Participant or any transferee (either being sometimes referred
to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set
forth in this Section 5 (the “Right of First Refusal”). 
 (a) Notice of Proposed Transfer. The Holder of
the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee
(“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Shares (the “Offered
Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). 

  
 -1-

 (b) Exercise of Right of First Refusal. At any time within thirty (30) days
after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at
the purchase price determined in accordance with subsection (c) below. 
 (c) Purchase Price. The purchase price
(“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section 5 shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash
consideration shall be determined by the Board of Directors of the Company in good faith. 
 (d) Payment. Payment of the
Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the
assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (e) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided
in this Section 5, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within one hundred and twenty
(120) days after the date of the Notice, that any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section 5 shall
continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its
assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 
 (f) Exception for Certain Family Transfers. Anything to the contrary contained in this Section 5 notwithstanding, the transfer of any or all of the Shares during the Participant’s
lifetime or on the Participant’s death by will or intestacy to the Participant’s immediate family or a trust for the benefit of the Participant’s immediate family shall be exempt from the provisions of this Section 5.
“Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the
provisions of this Section 5, and there shall be no further transfer of such Shares except in accordance with the terms of this Section 5. 
 (g) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any Shares upon the earlier of (i) the first sale of Common Stock by the Company in an underwritten
initial public offering, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 
 6. Tax Consultation. Participant understands that Participant may suffer adverse tax consequences as a result of Participant’s purchase or disposition of the Shares. Participant represents
that Participant has consulted with any tax consultants Participant deems advisable in connection with the purchase or disposition of the Shares and that Participant is not relying on the Company for any tax advice. 

  
 -2-

 7. Restrictive Legends and Stop-Transfer Orders. 

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

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

  
 -3-

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

	DATE	  	:	    		  	

 In connection with the purchase of the above-listed Securities, the undersigned Participant represents to the Company the
following: 
 (a) Participant is aware of the Company’s business affairs and financial condition and has acquired
sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Participant is acquiring these Securities for investment for Participant’s own account only and not with a view to, or for
resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 
 (b) Participant acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have not been registered under the Securities Act in reliance
upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Participant’s investment intent as expressed herein. In this connection, Participant understands that, in the view of the Securities
and Exchange Commission, the statutory basis for such exemption may be unavailable if Participant’s representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax
statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one (1) year or any other fixed period in the future. Participant further understands that the Securities must be held
indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Participant further acknowledges and understands that the Company is under no obligation to register the Securities.
Participant understands that the certificate evidencing the Securities shall be imprinted with any legend required under applicable state securities laws. 
 (c) Participant is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted
securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of the grant
of the Option to Participant, the exercise shall be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934,
ninety (90) days thereafter (or such 

  
 -1-

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

RING CENTRAL, INC. 
 2010 EQUITY INCENTIVE PLAN 
 RESTRICTED STOCK PURCHASE AGREEMENT

 THIS RESTRICTED STOCK PURCHASE AGREEMENT (the “Agreement”) is made between
                             (the “Purchaser”) and RingCentral, Inc. (the “Company”) or
its assignees of rights hereunder as of             ,         . 
 Unless otherwise defined herein, the terms defined in the 2010 Equity Incentive Plan shall have the same defined meanings in this Agreement. 

RECITALS 

A. Pursuant to the exercise of the option granted to Purchaser under the Plan and pursuant to the Stock Option Agreement – Early
Exercise & Acceleration (the “Option Agreement”) dated             .          by and between the Company and Purchaser with
respect to such grant (the “Option”), which Plan and Option Agreement are hereby incorporated by reference, Purchaser has elected to purchase                 
of those shares of Common Stock which have not become vested under the vesting schedule set forth in the Option Agreement (“Unvested Shares”). The Unvested Shares and the shares subject to the Option Agreement, which have become vested are
sometimes collectively referred to herein as the “Shares.” 
 B. As required by the Option Agreement, as a condition
to Purchaser’s election to exercise the option, Purchaser must execute this Agreement, which sets forth the rights and obligations of the parties with respect to Shares acquired upon exercise of the Option. 

1. Repurchase Option. 
 (a) If Purchaser’s status as a Service Provider is terminated for any reason, including for death and Disability, the Company shall have the right and option for one hundred eighty (180) days
from such date to purchase from Purchaser, or Purchaser’s personal representative, as the case may be, all of the Purchaser’s Unvested Shares as of the date of such termination at the price paid by the Purchaser for such Shares (the
“Repurchase Option”). 
 (b) Upon the occurrence of such termination, the Company may exercise its Repurchase Option
by delivering personally or by registered mail, to Purchaser (or his or her transferee or legal representative, as the case may be) with a copy to the escrow agent described in Section 2 below, a notice in writing indicating the Company’s
intention to exercise the Repurchase Option AND, at the Company’s option, (i) by delivering to the Purchaser (or the Purchaser’s transferee or legal representative) a check in the amount of the aggregate repurchase price, or
(ii) by the Company canceling an amount of the Purchaser’s indebtedness to the Company equal to the aggregate repurchase price, or (iii) by a combination of (i) and (ii) so that the combined payment and

  
 -1-

 
cancellation of indebtedness equals such aggregate repurchase price. Upon delivery of such notice and payment of the aggregate repurchase price in any of the ways described above, the Company
shall become the legal and beneficial owner of the Unvested Shares being repurchased and the rights and interests therein or relating thereto, and the Company shall have the right to retain and transfer to its own name the number of Unvested Shares
being repurchased by the Company. 
 (c) Whenever the Company shall have the right to repurchase Unvested Shares hereunder, the
Company may designate and assign one or more employees, officers, directors or stockholders of the Company or other persons or organizations to exercise all or a part of the Company’s Repurchase Option under this Agreement and purchase all or a
part of such Unvested Shares. 
 (d) If the Company does not elect to exercise the Repurchase Option conferred above by giving
the requisite notice within one hundred eighty (180) days following the termination, the Repurchase Option shall terminate. 
 (e) The Repurchase Option shall terminate with respect to the Unvested Shares in accordance with the Vesting Schedule contained in Purchaser’s Option Agreement. 

2. Transferability of the Shares; Escrow. 
 (a) Purchaser hereby authorizes and directs the Secretary of the Company, or such other person designated by the Company, to transfer the Unvested Shares as to which the Repurchase Option has been
exercised from Purchaser to the Company. 
 (b) To insure the availability for delivery of Purchaser’s Unvested Shares upon
repurchase by the Company pursuant to the Repurchase Option under Section 1, Purchaser hereby appoints the Secretary, or any other person designated by the Company as escrow agent (the “Escrow Agent”), as its attorney-in-fact to sell,
assign and transfer unto the Company, such Unvested Shares, if any, repurchased by the Company pursuant to the Repurchase Option and shall, upon execution of this Agreement, deliver and deposit with the Escrow Agent, the share certificates
representing the Unvested Shares, together with the stock assignment duly endorsed in blank, attached hereto as Exhibit C-2. The Unvested Shares and stock assignment shall be held by the Escrow Agent in escrow, pursuant to the Joint Escrow
Instructions of the Company and Purchaser attached as Exhibit C-3 hereto, until the Company exercises its Repurchase Option, until such Unvested Shares are vested, or until such time as this Agreement no longer is in effect. Upon vesting of
the Unvested Shares, the Escrow Agent shall promptly deliver to the Purchaser the certificate or certificates representing such Shares in the Escrow Agent’s possession belonging to the Purchaser, and the Escrow Agent shall be discharged of all
further obligations hereunder; provided, however, that the Escrow Agent shall nevertheless retain such certificate or certificates as Escrow Agent if so required pursuant to other restrictions imposed pursuant to this Agreement. 

(c) Neither the Company nor the Escrow Agent shall be liable for any act it may do or omit to do with respect to holding the Shares in
escrow and while acting in good faith and in the exercise of its judgment. 
 (d) Transfer or sale of the Shares is subject to
restrictions on transfer imposed by any applicable state and federal securities laws. Any transferee shall hold such Shares subject to all the provisions hereof and the Exercise Notice executed by the Purchaser with respect to any Unvested Shares
purchased by Purchaser and shall acknowledge the same by signing a copy of this Agreement. 

  
 -2-

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

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

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

  
 -3-

 This discussion is intended only as a summary of the general United States income tax laws
that apply to exercising Options as to Shares that have not yet vested and is accurate only as of the date this form Agreement was approved by the Board. The federal, state and local tax consequences to any particular taxpayer will depend upon his
or her individual circumstances. Purchaser is strongly encouraged to seek the advice of his or her own tax consultants in connection with the purchase of the Shares and the advisability of filing of the Election under Section 83(b) of the Code.
A form of Election under Section 83(b) is attached hereto as Exhibit C-4 for reference. 
 PURCHASER ACKNOWLEDGES
THAT IT IS PURCHASER’S SOLE RESPONSIBILITY AND NOT THE COMPANY’S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b) OF THE CODE, EVEN IF PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON PURCHASER’S BEHALF.

 9. Representations. Purchaser has reviewed with his or her own tax advisors the federal, state, local and foreign tax
consequences of this investment and the transactions contemplated by this Agreement. Purchaser is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. Purchaser understands that he or she
(and not the Company) shall be responsible for his or her own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement. 
 10. Entire Agreement; Governing Law. The Plan and Option Agreement are incorporated herein by reference. The Plan, the Option Agreement, the Exercise Notice, this Agreement, and the Investment
Representation Statement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Purchaser with respect to the subject matter
hereof, and may not be modified adversely to the Purchaser’s interest except by means of a writing signed by the Company and Purchaser. This Agreement is governed by the internal substantive laws but not the choice of law rules of California.

  
 -4-

 Purchaser represents that he or she has read this Agreement and is familiar with its terms
and provisions. Purchaser hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Board upon any questions arising under this Agreement. 

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

 Dear Legal Department: 
 As Escrow Agent for both RingCentral, Inc. (the “Company”), and the undersigned purchaser of stock of the Company (the “Purchaser”), you are hereby authorized and directed to hold the
documents delivered to you pursuant to the terms of that certain Restricted Stock Purchase Agreement (the “Agreement”) between the Company and the undersigned, in accordance with the following instructions: 

1. In the event the Company and/or any assignee of the Company (referred to collectively for convenience herein as the
“Company”) exercises the Company’s repurchase option set forth in the Agreement, the Company shall give to Purchaser and you a written notice specifying the number of shares of stock to be purchased, the purchase price, and the time
for a closing hereunder at the principal office of the Company. Purchaser and the Company hereby irrevocably authorize and direct you to close the transaction contemplated by such notice in accordance with the terms of said notice. 

2. At the closing, you are directed (a) to date the stock assignments necessary for the transfer in question, (b) to fill in
the number of shares being transferred, and (c) to deliver the stock assignments, together with the certificate evidencing the shares of stock to be transferred, to the Company or its assignee, against the simultaneous delivery to you of the
purchase price (by cash, a check, or some combination thereof) for the number of shares of stock being purchased pursuant to the exercise of the Company’s repurchase option. 

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

4. Upon written request of the Purchaser, but no more than once per calendar year, unless the Company’s repurchase option has been
exercised, you shall deliver to Purchaser a 

  
 -1-

 
certificate or certificates representing so many shares of stock as are not then subject to the Company’s repurchase option. Within one hundred and twenty (120) days after cessation of
Purchaser’s continuous employment by or services to the Company, or any parent or subsidiary of the Company, you shall deliver to Purchaser a certificate or certificates representing the aggregate number of shares held or issued pursuant to the
Agreement and not purchased by the Company or its assignees pursuant to exercise of the Company’s repurchase option. 
 5.
If at the time of termination of this escrow you should have in your possession any documents, securities, or other property belonging to Purchaser, you shall deliver all of the same to Purchaser and shall be discharged of all further obligations
hereunder. 
 6. Your duties hereunder may be altered, amended, modified or revoked only by a writing signed by all of the
parties hereto.

 The undersigned Participant has been granted an Option to purchase Common Stock of the Company, subject
to the terms and conditions of the Plan and this Option Agreement, as follows: 
  

					
	Date of Grant:	  	  
	  	
			
	Vesting Commencement Date:	  	  
	  	
			
	Exercise Price per Share:	  	  
	  	
			
	Total Number of Shares Granted:

Nonstatutory Stock Option	  	
			
	Term/Expiration Date:	  		  	

 Vesting Schedule: 
 This Option shall be exercisable, in whole or in part, according to the following vesting schedule, except that during the Termination Period the Option shall only be exercisable pursuant to the terms set
forth below: 
 Twenty-five percent (25%) of the Shares subject to the Option shall vest on the one
(1) year anniversary of the Vesting Commencement Date, and one forty-eighth (1/48th) of the Shares subject to the Option shall vest each month thereafter on the same day of the month as the Vesting Commencement Date (and if there is no corresponding day, on the last day of the
month), subject to Participant continuing to be a Service Provider through each such date. 

  
 1 

 Termination Period: 

This Option shall only be exercisable during the 90 (ninety) day period following the date Participant ceases to be a Service Provider,
unless such termination is due to Participant’s death or Disability, in which case this Option shall be exercisable during the Exercise Period(s) that occur(s) during the 6 (six) month period following the date Participant ceases to be a
Service Provider (both such periods of time constituting a “Termination Period”). Notwithstanding the foregoing sentence, in no event may this Option be exercised after the Term/Expiration Date as provided above and this Option may be
subject to earlier termination as provided in Section 13 of the Plan. 
  

	II.	AGREEMENT 

 1.
Grant of Option. The Administrator of the Company hereby grants to the Participant named in the Notice of Stock Option Grant in Part I of this Agreement (“Participant”), an option (the “Option”) to purchase the number of
Shares set forth in the Notice of Stock Option Grant, at the exercise price per Share set forth in the Notice of Stock Option Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan, which is incorporated herein
by reference. Subject to Section 18 of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall prevail. 

If designated in the Notice of Stock Option Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as
an Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the $100,000 rule of Code Section 422(d), this Option shall be treated as a Nonstatutory Stock Option (“NSO”). Further,
if for any reason this Option (or portion thereof) shall not qualify as an ISO, then, to the extent of such nonqualification, such Option (or portion thereof) shall be regarded as a NSO granted under the Plan. In no event shall the Administrator,
the Company or any Parent or Subsidiary or any of their respective employees or directors have any liability to Participant (or any other person) due to the failure of the Option to qualify for any reason as an ISO. 

2. Exercise of Option. 
 (a) Right to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice of Stock Option Grant and with the applicable provisions of the
Plan and this Option Agreement. Notwithstanding the foregoing, prior to the expiration of the lock-up period following the Company’s first filing of a registration statement under the Securities Act, as described in Section 4 of this
Agreement, and subject to the Termination Period provision set forth in the Notice of Stock Option Grant and Section 13(c) of the Plan, this Option shall only be exercisable during the following exercise periods (the “Exercise
Periods”), unless otherwise approved by the Board of Directors: 
 (b) Method of Exercise. This Option shall be
exercisable by delivery of an exercise notice in the form attached as Exhibit A (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which shall state the election to
exercise the Option, the number of Shares with respect to which the Option is being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company. The Exercise Notice shall be
accompanied by payment of the aggregate Exercise Price as to all Exercised Shares, together with any applicable tax withholding. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice
accompanied by the aggregate Exercise Price, together with any applicable tax withholding. 

  
 2 

 No Shares shall be issued pursuant to the exercise of an Option unless such issuance and
such exercise comply with Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to Participant on the date on which the Option is exercised with respect to such Shares. 

3. Participant’s Representations. In the event the Shares have not been registered under the Securities Act of 1933, as
amended (the “Securities Act”), at the time this Option is exercised, Participant shall, if required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment
Representation Statement in the form attached hereto as Exhibit B. 
 4. Lock-Up Period. Participant hereby
agrees that Participant shall not offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of,
directly or indirectly, any Common Stock (or other securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or
other securities) of the Company held by Participant (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred and
eighty (180) days following the effective date of any registration statement of the Company filed under the Securities Act (or such other period as may be requested by the Company or the underwriters to accommodate regulatory restrictions on
(i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any
successor provisions or amendments thereto). 
 Participant agrees to execute and deliver such other agreements as may be
reasonably requested by the Company or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock
(or other securities) of the Company, Participant shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the
Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in this Section 4 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or
similar forms that may be promulgated in the future, or a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with
respect 

  
 3 

 
to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred and eighty (180) day (or other) period. Participant agrees that any
transferee of the Option or shares acquired pursuant to the Option shall be bound by this Section 4. 
 5. Method of
Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the election of the Participant: 
 (a) cash; 
 (b) check; 

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

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

 6. Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been approved by the
stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any Applicable Law. Further, this Option shall only be exercisable within an
Exercise Period, under the terms of Section 13(c) of the Plan, or as otherwise provided under the Termination Period in the Notice of Stock Option Grant, as applicable. 
 7. Non-Transferability of Option. 
 (a) This Option may not be transferred
in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Participant only by Participant. The terms of the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of Participant. 
 (b) Further, until the Company becomes subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, or after the Administrator determines that it is, will, or may no longer be relying upon the exemption from registration of Options under the Exchange Act as set forth in Rule 12h-1(f)
promulgated under the Exchange Act (the “Reliance End Date”), Participant shall not transfer this Option or, prior to exercise, the Shares subject to this Option, in any manner other than (i) to persons who are “family
members” (as defined in Rule 701(c)(3) of the Securities Act) through gifts or domestic relations orders, or (ii) to an executor or guardian of Participant upon the death or disability of Participant. Until the Reliance End Date, the
Options and, prior to exercise, the Shares subject to this Option, may not be pledged, hypothecated or otherwise transferred or disposed of, including by entering into any short position, any “put equivalent position” or any “call
equivalent position” (as defined in Rule 16a-1(h) and Rule 16a-1(b) of the Exchange Act, respectively), other than as permitted in clauses (i) and (ii) of this paragraph. 

  
 4 

 8. Term of Option. This Option may be exercised only within the term set out in the
Notice of Stock Option Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Option Agreement. 
 9. Tax Obligations. 
 (a) Tax Withholding. Participant agrees to make
appropriate arrangements with the Company (or the Parent or Subsidiary employing or retaining Participant) for the satisfaction of all Federal, state, local and foreign income and employment tax withholding requirements applicable to the Option
exercise. Participant acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver the Shares if such withholding amounts are not delivered at the time of exercise. 

(b) Notice of Disqualifying Disposition of ISO Shares. If the Option granted to Participant herein 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, or (ii) the date one (1) year after the date of exercise, 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. 

(c) Code Section 409A. Under Code Section 409A, an Option that vests after December 31, 2004 (or that vested on or
prior to such date but which was materially modified after October 3, 2004) that was granted with a per Share exercise price that is determined by the Internal Revenue Service (the “IRS”) to be less than the Fair Market Value of a
Share on the date of grant (a “discount option”) may be considered “deferred compensation.” An Option that is a “discount option” may result in (i) income recognition by Participant prior to the exercise of the
Option, (ii) an additional twenty percent (20%) federal income tax, and (iii) potential penalty and interest charges. The “discount option” may also result in additional state income, penalty and interest tax to the
Participant. Participant acknowledges that the Company cannot and has not guaranteed that the IRS will agree that the per Share exercise price of this Option equals or exceeds the Fair Market Value of a Share on the date of grant in a later
examination. Participant agrees that if the IRS determines that the Option was granted with a per Share exercise price that was less than the Fair Market Value of a Share on the date of grant, Participant shall be solely responsible for
Participant’s costs related to such a determination. 
 10. Entire Agreement; Governing Law. The Plan is
incorporated herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and
Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant. This Option Agreement is governed by the internal
substantive laws but not the choice of law rules of California. 
 11. No Guarantee of Continued Service. PARTICIPANT
ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING

  
 5 

 
PARTICIPANT) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS
CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH
PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 

Participant acknowledges receipt of a copy of the Plan and represents that he or she is familiar with the terms and provisions thereof,
and hereby accepts this Option subject to all of the terms and provisions thereof. Participant has reviewed the Plan and this Option in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option and fully
understands all provisions of the Option. Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan or this Option. Participant further agrees
to notify the Company upon any change in the residence address indicated below.

 EXHIBIT A 

2010 EQUITY INCENTIVE PLAN 
 EXERCISE NOTICE 
 RingCentral, Inc. 

1400 Fashion Island Blvd., 7th Floor 
 San
Mateo, CA 94404 
 Attention: Legal Department 
 1. Exercise of Option. Effective as of today,             ,         , (the “Exercise
Date”) the undersigned (“Participant”) hereby elects to exercise Participant’s option (the “Option”) to purchase                  shares of
the Common Stock (the “Shares”) of RingCentral, Inc. (the “Company”) under and pursuant to the 2010 Equity Incentive Plan (the “Plan”) and the Stock Option Agreement dated
            ,          (the “Option Agreement”). 
 2. Delivery of Payment. Participant herewith delivers to the Company the full purchase price of the Shares, as set forth in the Option Agreement, and any and all withholding taxes due in connection
with the exercise of the Option. 
 3. Representations of Participant. Participant acknowledges that Participant has
received, read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms and conditions. 
 4. Rights as Stockholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to
vote or receive dividends or any other rights as a stockholder shall exist with respect to the Common Stock subject to an Award, notwithstanding the exercise of the Option. The Shares shall be issued to Participant as soon as practicable after the
Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for which the record date is prior to the date of issuance except as provided in Section 13 of the Plan. 

5. Repurchase Rights. The Company shall have the right within ninety (90) days of the date hereof and during any Termination
Period, as defined in the Option Agreement, to repurchase the Shares purchased pursuant to this Exercise Notice by giving the Participant notice that it has chosen to exercise such repurchase rights and paying the Fair Market Value determined by the
most recent 409A valuation of the Company’s Common Stock prior to the Exercise Date (the “Repurchase Price”). This repurchase right shall terminate as to any Shares upon the earlier of (i) the first sale of Common Stock of the
Company to the general public in an underwritten initial public offering, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 

 6. Acknowledgement of Repurchase Price. Participant acknowledges that the Repurchase
Price is equal to the most recent valuation of the Company’s Common Stock for purposes of compliance with Code Section 409A as determined by the Board of Directors of the Company prior to the Exercise Date. By choosing to exercise his or
her Option, Participant agrees that he or she will not contest any repurchase based on Section 5 by arguing that the price is not equal to fair market value. 
 7. Company’s Right of First Refusal. Once the Company’s repurchase rights under Section 5 have expired, before any Shares held by Participant or any transferee (either being
sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and
conditions set forth in this Section 7 (the “Right of First Refusal”). 
 (a) Notice of Proposed Transfer.
The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other
transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Shares (the
“Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). 
 (b)
Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the
Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with subsection (c) below. 
 (c) Purchase Price. The purchase price (“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section 7 shall be the Offered Price. If the Offered
Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 

(d) Payment. Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or
in the manner and at the times set forth in the Notice. 
 (e) Holder’s Right to Transfer. If all of the Shares
proposed in the Notice to be transferred to a given Proposed Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section 7, then the Holder may sell or otherwise transfer such Shares to that Proposed
Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within one hundred and twenty (120) days after the date of the Notice, that any such sale or other transfer is effected in
accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section 7 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in
the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may
be sold or otherwise transferred. 

  
 2 

 (f) Exception for Certain Family Transfers. Anything to the contrary contained in
this Section 5 notwithstanding, the transfer of any or all of the Shares during the Participant’s lifetime or on the Participant’s death by will or intestacy to the Participant’s immediate family or a trust for the benefit of the
Participant’s immediate family shall be exempt from the provisions of this Section 7. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the
transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section 7, and there shall be no further transfer of such Shares except in accordance with the terms of this Section 7.

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

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

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

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED,
SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
THEREWITH.

	DATE	  	:	  	

 In connection with the purchase of the above-listed Securities, the undersigned Participant represents to
the Company the following: 
 (a) Participant is aware of the Company’s business affairs and financial condition and has
acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Participant is acquiring these Securities for investment for Participant’s own account only and not with a view to, or
for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 
 (b) Participant acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have not been registered under the Securities Act in reliance
upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Participant’s investment intent as expressed herein. In this connection, Participant understands that, in the view of the Securities
and Exchange Commission, the statutory basis for such exemption may be unavailable if Participant’s representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax
statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one (1) year or any other fixed period in the future. Participant further understands that the Securities must be held
indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Participant further acknowledges and understands that the Company is under no obligation to register the Securities.
Participant understands that the certificate evidencing the Securities shall be imprinted with any legend required under applicable state securities laws. 
 (c) Participant is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted
securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of the grant
of the Option to Participant, the exercise shall be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934,
ninety (90) days thereafter (or such 

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

3. Selection of Participants and Determination of Awards. 

(a) Selection of Participants. The Committee, in its sole discretion, will select the Employees who will be Participants for any
Performance Period. Participation in the Plan is in the sole discretion of the Committee, on a Performance Period by Performance Period basis. Accordingly, an Employee who is a Participant for a given Performance Period in no way is guaranteed or
assured of being selected for participation in any subsequent Performance Period or Periods. 
 (b) Determination of Target
Awards. The Committee, in its sole discretion, will establish a Target Award for each Participant, which generally will be a percentage of a Participant’s average annual base salary for the Performance Period. 

(c) Bonus Pool. Each Performance Period, the Committee, in its sole discretion, will establish a Bonus Pool. Actual Awards will be
paid from the Bonus Pool. 
 (d) Discretion to Modify Awards. Notwithstanding any contrary provision of the Plan, the
Committee may, in its sole discretion and at any time, (i) increase, reduce or eliminate a Participant’s Actual Award, and/or (ii) increase, reduce or eliminate the amount allocated to the Bonus Pool. The Committee may determine the

performance goals may be based on GAAP or Non-GAAP results and any actual results may be adjusted by the Committee for one-time items or unbudgeted or unexpected items when determining whether the performance goals have been met. The goals may be on
the basis of any factors the Committee determines relevant, and may be on an individual, divisional, business unit or Company-wide basis. The performance goals may differ from Participant to Participant and from award to award. The Committee may, in
its discretion, determine to set forth the applicable performance goals in writing from time-to-time, which writing shall be attached hereto as Appendix A. Failure to meet the goals will result in a failure to earn the Target Award, except as
provided in Section 3(d). 
 4. Payment of Awards. 

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

(b) Timing of Payment. Payment of each Actual Award shall be made as soon as practicable as determined by the Committee after the
end of the Performance Period during which the Actual Award was earned, but in no event later than the fifteenth day of the third month of the Fiscal Year following the date the Participant’s Actual Award is no longer subject to a substantial
risk of forfeiture. Unless otherwise determined by the Committee, a Participant must be employed by the Company or any Affiliate on the last day of the Performance Period to receive a payment under the Plan. 

It is the intent that this Plan comply with the requirements of Code Section 409A so that none of the payments to be provided
hereunder will be subject to the additional tax imposed under Code Section 409A, and any ambiguities herein will be interpreted to so comply. 
 (c) Form of Payment. Each Actual Award will be paid in cash (or its equivalent) in a single lump sum. 
 (d) Payment in the Event of Death or Disability. If a Participant dies or becomes Disabled prior to the payment of an Actual Award earned by him or her prior to death or Disability for a prior
Performance Period, the Actual Award will be paid to his or her estate or to the Participant, as the case may be, subject to the Committee’s discretion to reduce or eliminate any Actual Award otherwise payable. 

5. Plan Administration. 
 (a) Committee is the Administrator. The Plan will be administered by the Committee or, if no Committee has been appointed, the Plan shall be administered by the Board. The Committee will consist of
not less than two (2) members of the Board. The members of the Committee will be appointed from time to time by, and serve at the pleasure of, the Board. 

  
 -3-

 (b) Committee Authority. It will be the duty of the Committee to administer the Plan
in accordance with the Plan’s provisions. The Committee will have all powers and discretion necessary or appropriate to administer the Plan and to control its operation, including, but not limited to, the power to (i) determine which
Employees will be granted awards, (ii) prescribe the terms and conditions of awards, (iii) interpret the Plan and the awards, (iv) adopt such procedures and subplans as are necessary or appropriate to permit participation in the Plan

rules. 
 (c) Decisions Binding. All determinations and decisions made by the Committee, the Board, and any delegate of

 (d) Delegation by Committee. The Committee, in its sole discretion and on such terms and conditions as it may provide, may delegate all or part of its authority and powers under the Plan to one or
more directors and/or officers of the Company. 
 (e) Indemnification. Each person who is or will have been a member
of the Committee will be indemnified and held harmless by the Company against and from (i) any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim,
action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan or any award, and (ii) from any and all amounts paid by him or her in settlement
thereof, with the Company’s approval, or paid by him or her in satisfaction of any judgment in any such claim, action, suit, or proceeding against him or her, provided he or she will give the Company an opportunity, at its own expense, to
handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification will not be exclusive of any other rights of indemnification to which such persons may be entitled under
the Company’s Articles of Incorporation or Bylaws, by contract, as a matter of law, or otherwise, or under any power that the Company may have to indemnify them or hold them harmless. 

6. General Provisions. 
 (a) Tax Withholding. The Company will withhold all applicable taxes from any Actual Award, including any federal, state and local taxes (including, but not limited to, the Participant’s FICA
and SDI obligations). 
 (b) No Effect on Employment or Service. Nothing in the Plan will interfere with or limit in any
way the right of the Company to terminate any Participant’s employment or service at any time, with or without cause. For purposes of the Plan, transfer of employment of a Participant between the Company and any one of its Affiliates (or
between Affiliates) will not be deemed a Termination of Service. Employment with the Company and its Affiliates is on an at-will basis only. 

  
 -4-

 
The Company expressly reserves the right, which may be exercised at any time and without regard to when during a Performance Period such exercise occurs, to terminate any individual’s
employment with or without cause, and to treat him or her without regard to the effect that such treatment might have upon him or her as a Participant. 
 (c) Participation. No Employee will have the right to be selected to receive an award under this Plan, or, having been so selected, to be selected to receive a future award. 

(d) Successors. All obligations of the Company under the Plan, with respect to awards granted hereunder, will be binding on any
successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business or assets of the Company. 

(e) Beneficiary Designations. If permitted by the Committee, a Participant under the Plan may name a beneficiary or beneficiaries
to whom any vested but unpaid award will be paid in the event of the Participant’s death. Each such designation will revoke all prior designations by the Participant and will be effective only if given in a form and manner acceptable to the
Committee. In the absence of any such designation, any vested benefits remaining unpaid at the Participant’s death will be paid to the Participant’s estate. 
 (f) Nontransferability of Awards. No award granted under the Plan may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will, by the laws of descent and
distribution, or to the limited extent provided in Section 6(e). All rights with respect to an award granted to a Participant will be available during his or her lifetime only to the Participant. 

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

been included. 
 (c) Requirements of Law. The granting of awards under the Plan will be subject to all applicable laws,
rules and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. 

(d) Governing Law. The Plan and all awards will be construed in accordance with and governed by the laws of the State of
California, but without regard to its conflict of law provisions.

 APPENDIX A 

2012 Performance Goals 
 (As amended on September 18, 2012) 
  

	1.	H1 2012 Performance Period and Performance Goals. For the first half of calendar year 2012, there are two quarterly Performance Periods,
ending on March 31 and June 30 (each, an “H1 2012 Performance Period”). For each H1 2012 Performance Period, there are two equally weighted (50% each) performance goals (each, an “H1 2012 Performance Goal”): H1 Revenue and H1
Free Cash Flow (each as defined below). The chart below illustrates the H1 Revenue and H1 Free Cash Flow targets for each of the H1 2012 Performance Periods. 

 

					
	 H1 2012 Performance Period

	 Q2
	  	$27.8	  	($8.3)
	 TOTAL
	  	$52.6	  	($12.6)

 “H1 Revenue” means as to any H1 2012 Performance Period, the Company’s or a
business unit’s net revenues generated from third parties. 
 “H1 Free Cash Flow” means as to any H1 2012
Performance Period, the Company’s cash flow from operations less the capital expenditures, as presented on the quarterly cash flow statement. The free cash flow target for H1 2012 assumes that the Company will have negative free cash flow in
each quarter. 
  

	2.	Funding of H1 2012 Bonus Pool. Subject to the terms of Plan, including but not limited to Section 3(d) of the Plan, following the end of an H1 2012
Performance Period, the Committee will determine the extent to which each of the H1 2012 Performance Goals are achieved in accordance with the following guidelines. 

 

	 	a.	If the Company achieves less than 90% of the H1 Revenue H1 2012 Performance Goal OR achieves more than 111.1% (negative) of the H1 Free Cash Flow H1 2012
Performance Goal during an H1 2012 Performance Period, the H1 2012 Bonus Pool will not fund. 

	 	b.	If the Company achieves 90% or more of the H1 Revenue H1 2012 Performance Goal AND achieves 111.1% (negative) or less of the H1 Free Cash Flow H1 2012
Performance Goal, the H1 2012 Bonus Pool will fund as follows with respect to each H1 2012 Performance Goal during such H1 2012 Performance Period based on the percentage achievement. The chart below illustrates the funding multiple that will apply
to each H1 Performance Goal.

 Illustration 
 For example, if the Company achieves its H1 Revenue at
93% of target and H1 Free Cash Flow at 111.1%, the H1 2012 Bonus Pool will fund as to 91.5%, determined as follows: 
  

	 	•	 	 46.5% on achievement of the revenue goal (50% weighted target * .93x) 

 

	 	•	 	 111.1% on achievement of the free cash flow goal (50% weighted target * .90x) 

 

	3.	 H2 2012 Performance Period and Performance Goals. For the second half of calendar year 2012, there are two quarterly
Performance Periods, ending on September 30 and December 31 (each, an “H2 2012 Performance Period”). For each H2 2012 Performance Period, there are two

equally weighted (50% each) performance goals (each, an “H2 2012 Performance Goal”): H2 Revenue and H2 Operating Income (each as defined below). The chart below illustrates the H2
Revenue and H2 Operating Income targets for each of the H2 2012 Performance Periods.

 “H2 Revenue” means as to any H2 2012 Performance Period, the Company’s or a
business unit’s net revenues generated from third parties. 
 “H2 Operating Income” means as to any H2 2012
Performance Period, the Company’s non-GAAP income from operations (revenues less cost of revenues and operating expenses, excluding the impact of stock-based compensation expense, amortization of acquisition related intangibles, and income tax
effects of the excluded items), as adjusted for certain acquisitions, as presented on the quarterly income statement. The operating income target for H2 2012 assumes that the Company will have negative operating income in each quarter. 

 

	4.	Funding of H2 2012 Bonus Pool. Subject to the terms of Plan, including but not limited to Section 3(d) of the Plan, following the end of an H2 2012
Performance Period, the Committee will determine the extent to which each of the H2 2012 Performance Goals are achieved in accordance with the following guidelines. 

 

	 	c.	If the Company achieves less than 90% of the H2 Revenue H2 2012 Performance Goal OR achieves more than125% (negative) of the H2 Operating Income H2 2012
