Section 4 of the Plan. 
 (b) “Applicable Laws” means the requirements relating to the administration of
equity-based awards and the related issuance of Shares under U.S. state corporate laws, U.S. federal and state securities laws, the Code, any stock exchange or quotation system on which the Common Stock is listed or quoted and the applicable
securities or exchange control laws of any foreign country or jurisdiction where Awards are, or will be, granted under the Plan.

 (e) “Board” means the Board of Directors of the Company. 
 (f)
“Change in Control” means the occurrence of any of the following events: 
 (i) A change in the ownership of
the Company which occurs on the date that any one person, or more than one person acting as a group (“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than
fifty percent (50%) of the total voting power of the stock of the Company; provided, however, that for purposes of this subsection, the acquisition of additional stock by any one Person, who is considered to own more than fifty percent
(50%) of the total voting power of the stock of the Company will not be considered a Change in Control; or 

 (ii) A change in the effective control of the Company which occurs on the date that a
majority of members of the Board is replaced during any twelve (12) month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For purposes
of this subsection (ii), if any Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change in Control; or 

(iii) A change in the ownership of a substantial portion of the Company’s assets which occurs on the date that any Person acquires
(or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total gross fair market value equal to or more than fifty percent
(50%) of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions; provided, however, that for purposes of this subsection (iii), the following will not constitute a change in
the ownership of a substantial portion of the Company’s assets: (A) a transfer to an entity that is controlled by the Company’s stockholders immediately after the transfer, or (B) a transfer of assets by the Company to:
(1) a stockholder of the Company (immediately before the asset transfer) in exchange for or with respect to the Company’s stock, (2) an entity, fifty percent (50%) or more of the total value or voting power of which is
owned, directly or indirectly, by the Company, (3) a Person, that owns, directly or indirectly, fifty percent (50%) or more of the total value or voting power of all the outstanding stock of the Company, or (4) an entity, at least

of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets. 
 For purposes of this definition, 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 state 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. 
 (g)

 (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

 (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 reported), as reported in The Wall Street Journal or such other source as the Administrator deems reliable;

statement in Form S-1 filed with the Securities and Exchange Commission for the initial public offering of the Company’s Common Stock; or 
 (iv) In the absence of an established market for the Common Stock, the Fair Market Value will be determined in good faith by the Administrator.

 -5-

 
under the Company’s 2007 Equity Incentive Plan, as amended (the “2007 Plan”) that, after the Registration Date, expire or otherwise terminate without having been
exercised in full and Shares issued pursuant to awards granted under the 2007 Plan that, after the Registration Date, are forfeited to or repurchased by the Company, with the maximum number of Shares to be added to the Plan from the 2007 Plan equal
to 137,000,000 Shares. The Shares may be authorized, but unissued, or reacquired Common Stock. 
 (b) Automatic Share Reserve
Increase. The number of Shares available for issuance under the Plan will be increased on the first day of each Fiscal Year beginning with the 2014 Fiscal Year, in an amount equal to the least of (i) 60,000,000 Shares, (ii) 5% of the
outstanding Shares on the last day of the immediately preceding Fiscal Year or (iii) such number of Shares determined by the Board. 
 (c) 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,
Restricted Stock Units, Performance Units or Performance Shares, is forfeited to or repurchased by the Company due to 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 (i.e., the net Shares 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, Restricted Stock Units,
Performance Shares or Performance Units are repurchased by the Company or are forfeited to the Company, 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 14, 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 Section 422 of the Code and the Treasury Regulations promulgated thereunder, any Shares that become available for issuance under the Plan pursuant to
Sections 3(b) and 3(c). 
 (d) 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. 

  
 -6-

 (ii) Section 162(m). To the extent that the Administrator determines it to be
desirable to qualify Awards granted hereunder as “performance-based compensation” within the meaning of Section 162(m) of the Code, the Plan will be administered by a Committee of two (2) or more “outside
directors” within the meaning of Section 162(m) of the Code. 
 (iii) Rule 16b-3. To the extent desirable
to qualify transactions hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder will be structured to satisfy the requirements for exemption under Rule 16b-3. 

(iv) 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; 
 (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 19 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(b) of the Plan regarding Incentive Stock Options); 

  
 -7-

 (x) to allow Participants to satisfy withholding tax obligations in such manner as
prescribed in Section 15 of the Plan; 
 (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 would otherwise 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, Restricted Stock Units, Performance Shares and Performance Units may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. 

6. Stock Options. 
 (a) Limitations. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent
that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the 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(a), 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. 
 (b) Term of Option. The term of each Option will be stated in the Award Agreement. In the case of an Incentive Stock Option, the term will be ten (10) years from the date of grant or such
shorter term as may be provided in the Award Agreement. Moreover, 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. 

  
 -8-

 (c) Option Exercise Price and Consideration. 

(i) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option will be determined
by the Administrator, subject to the following: 
 (1) In the case of an Incentive Stock Option 

(A) granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the 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.

 (B) granted to any Employee other than an Employee described in paragraph (A) immediately above, the per Share exercise
price will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 
 (2) In
the case of a Nonstatutory Stock Option, the per Share exercise price will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

(3) Notwithstanding the foregoing, 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, Section 424(a) of the Code. 

(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. 
 (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 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 a broker-assisted (or other) 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. 

(d) 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) a 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 withholding taxes). Full payment may consist of any 

  
 -9-

 
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 14 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 such period
of time as is specified in the Award Agreement to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a
specified time in the Award Agreement, the Option will remain exercisable for three (3) months following the Participant’s 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 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 such period of time as is specified in the Award Agreement to the extent the
Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for
twelve (12) months following the Participant’s 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 following the
Participant’s death within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of death (but in no event may the option be exercised later than the expiration of the term of such Option
as set forth in the Award Agreement), by the Participant’s designated beneficiary, provided the right to designate a beneficiary is set forth in the Award Agreement and such beneficiary has been designated prior to 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 

  
 -10-

 
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. In the
absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following Participant’s death. 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. 
 (v) Extension if Exercise Prevented by Law. Notwithstanding the foregoing, if
the exercise of an Option within the applicable time periods set forth in Section 7(d) is prevented by the provisions of Section 20 below, the Option shall remain exercisable until thirty (30) days (or such longer period of time
as determined by the Administrator, in its discretion) after the date the Participant is notified by the Company that the Option is exercisable (but in no event later than the expiration of the term of such Option as set forth in the Award
Agreement). 
 7. 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 7 or the Award Agreement, 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 7, 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. 
 (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 

  
 -11-

 
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. 
 8. 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 under the Plan, 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, divisional, business unit, or individual goals (including, but not limited to, continued employment or service), applicable federal or state securities laws 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 only 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. 
 9. 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 Stock Appreciation Rights granted
to any Service Provider. 
 (c) Exercise Price and Other Terms. The per share exercise price for the Shares to be issued
pursuant to exercise of a Stock Appreciation Right will be determined by the 

  
 -12-

 
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. 

(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(b) relating to the maximum term and Section 6(d) 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. 
 10. Performance Units and Performance Shares. 

(a) Grant of Performance Units/Shares. Performance Units and Performance Shares 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. The Administrator will have complete discretion in determining the number of Performance Units and Performance Shares granted to each Participant. 

(b) Value of Performance Units/Shares. Each Performance Unit will have an initial value that is established by the Administrator
on or before the date of grant. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the date of grant. 
 (c) Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting provisions (including, without limitation, continued status as a Service
Provider) in its discretion which, depending on the extent to which they are met, will determine the number or value of Performance Units/Shares that will be paid out to the Service Providers. The time period during which the performance
objectives or other vesting provisions must be met will be called the “Performance Period.” Each Award of Performance Units/Shares will be evidenced by an Award Agreement that will specify the Performance Period, and such other

  
 -13-

 
terms and conditions as the Administrator, in its sole discretion, will determine. The Administrator may set performance objectives based upon the achievement of Company-wide, divisional,
business unit or individual goals (including, but not limited to, continued employment or service), applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion. 

(d) Earning of Performance Units/Shares. After the applicable Performance Period has ended, the holder of Performance Units/Shares
will be entitled to receive a payout of the number of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance objectives or other vesting
provisions have been achieved. After the grant of a Performance Unit/Share, the Administrator, in its sole discretion, may reduce or waive any performance objectives or other vesting provisions for such Performance Unit/Share. 

(e) Form and Timing of Payment of Performance Units/Shares. Payment of earned Performance Units/Shares will be made as soon as
practicable after the expiration of the applicable Performance Period. The Administrator, in its sole discretion, may pay earned Performance Units/Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of
the earned Performance Units/Shares at the close of the applicable Performance Period) or in a combination thereof. 
 (f)
Cancellation of Performance Units/Shares. On the date set forth in the Award Agreement, all unearned or unvested Performance Units/Shares will be forfeited to the Company, and again will be available for grant under the Plan. 

11. Outside Director Limitations. 
 (a) Cash-Settled Awards. No Outside Director may be granted, in any fiscal year of the Company, cash-settled Awards with a grant date fair value (determined in accordance with U.S. generally
accepted accounting principles) of more than $4,000,000, increased to $8,000,000 in connection with his or her initial service. 
 (b) Stock-Settled Awards. No Outside Director may be granted, in any fiscal year of the Company, stock-settled Awards with a grant date fair value (determined in accordance with U.S. generally
accepted accounting principles) of more than $4,000,000, increased to $8,000,000 in connection with his or her initial service. 
 12. 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. 

  
 -14-

 13. Transferability of Awards. Unless determined otherwise by the Administrator, an
Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Participant, only by the Participant. If
the Administrator makes an Award transferable, such Award will contain such additional terms and conditions as the Administrator deems appropriate. 
 14. 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, and the numerical Share limits in Section 3 of the Plan. 

(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) Change in Control. In the event of a merger of the Company with or into another corporation or other entity or a
Change in Control, each outstanding Award will be treated as the Administrator determines, including, without limitation, that (i) Awards may 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 14(c), the Administrator will not be required to treat all Awards similarly in the transaction. 

In the event that the successor corporation does not assume or substitute for the Award, 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 

  
 -15-

 
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
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. 
 For the purposes of this subsection (c), an
Award will be considered assumed if, following the Change in Control, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, or
other securities or property) received in the 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 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, Performance Unit or Performance Share, 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 Change in Control. 

Notwithstanding anything in this Section 14(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. 
 (d) Outside Director Awards. With respect to Awards granted to an Outside Director that are assumed or substituted for, if on the date of or following such assumption or substitution the
Participant’s status as a Director or a director of the successor corporation, as applicable, is terminated other than upon a voluntary resignation by the Participant (unless such resignation is at the request of the acquirer), then the
Participant will fully vest in and have the right to exercise Options and/or Stock Appreciation Rights as to all of the Shares underlying such Award, including those Shares which 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. 

  
 -16-

 15. Tax. 
 (a) Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof) or such earlier time as any tax withholding obligations are due, 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) (a) paying cash, (b) electing to have the Company withhold otherwise deliverable cash (including cash from the sale of Shares issued to Participant) or Shares having a Fair Market Value equal to the minimum statutory
amount required to be withheld, or (c) delivering to the Company already-owned Shares having a Fair Market Value equal to the minimum statutory amount required to be withheld. 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. 
 (c) 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 such that the grant, payment, settlement or deferral will not be subject to the
additional tax or interest applicable under 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 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. 
 16. 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 or any Parent or Subsidiary of the Company, nor will they interfere in any way with the
Participant’s right or the Company’s right, or Parent’s or Subsidiary’s right, to terminate such relationship at any time, with or without cause, to the extent permitted by Applicable Laws. 

17. 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-

 18. Term of Plan. Subject to Section 22 of the Plan, the Plan will become
effective upon the later to occur of (i) its adoption by the Board or (ii) the business day immediately prior to the Registration Date. It will continue in effect for a term of ten (10) years from the date adopted by the Board, unless
terminated earlier under Section 19 of the Plan. 
 19. Amendment and Termination of the Plan. 

(a) Amendment and Termination. The Administrator 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 materially 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. 

20. 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. 
 (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. 
 21. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction or to complete or comply with the requirements of any registration
or other qualification of the Shares under any state, federal or foreign law or under the rules and regulations of the Securities and Exchange Commission, the stock exchange on which Shares of the same class are then listed, or any other
governmental or regulatory body, which authority, registration, qualification or rule compliance is deemed by the Company’s counsel to be necessary or advisable for the 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, registration, qualification or rule compliance will not have been obtained. 

22. 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.

Unless otherwise defined herein, the terms defined in the Twitter, Inc. 2013 Equity Incentive Plan (the “Plan”) will have the
same defined meanings in this Stock Option Agreement (the “Agreement”), including the Notice of Stock Option Grant (the “Notice of Grant”) and Terms and Conditions of Stock Option Grant, attached hereto as Exhibit A.

 Vesting Schedule: 
 Subject to accelerated vesting as set forth below or in the Plan, this Option will be exercisable, in whole or in part, in accordance with the following 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 

  
 - 1 -

 
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.] 
 Notwithstanding the foregoing, the vesting of
the Shares subject to the Option shall be subject to any vesting acceleration provisions applicable to this Option contained in the Plan and/or any employment or service agreement, offer letter, change in control severance agreement or policy, or
any other agreement or policy that, prior to and effective as of the date of this Agreement, has been entered into or agreed upon, as the case may be, between Participant and the Company or any parent or subsidiary corporation of the Company
(such agreement or policy, a “Separate Agreement”) to the extent not otherwise duplicative of the vesting terms described above (by way of example, if a Separate Agreement provides for different acceleration of vesting provisions for
all of Participant’s stock options upon a termination of Participant as a Service Provider for “good reason” that is defined differently, and the Participant’s status as a Service Provider terminates in a manner that would
trigger “good reason” under the Separate Agreement but not under this Agreement, the Participant would remain entitled to the acceleration of vesting under the Separate Agreement). 

Termination Period: 
 Except as provided in a Separate Agreement, this Option will be exercisable for three (3) months after Participant ceases to be a Service Provider, unless such termination is due to
Participant’s death or Disability, in which case this Option will be exercisable for twelve (12) months after Participant ceases to be a Service Provider. Notwithstanding the foregoing sentence, if the exercise of the Option within the
applicable time periods set forth in the preceding sentence is prevented by Section 20 of the Plan, the Option shall remain exercisable until thirty (30) days (or such longer period of time as determined by the Administrator, in its
discretion) after the date Participant is notified by the Company that the Option is exercisable, but in any event no later than the expiration of the term of the Option as set forth in the Notice of Grant. Notwithstanding anything herein to the
contrary, in no event may this Option be exercised after the Term/Expiration Date as provided above and may be subject to earlier termination as provided in Section 14(c) of the Plan.

 By Participant’s signature and the signature of the Company’s representative
below, Participant and the Company agree that this Option is granted under and governed by the terms and conditions of the Plan and this Agreement, including exhibits hereto, all of which are made a part of this document. Participant has reviewed
the Plan and this Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Agreement and fully understands all provisions of the Plan and Agreement. Participant hereby agrees to accept as binding,
conclusive and final all decisions or interpretations of the Administrator upon any questions relating to the Plan and Agreement. Participant further agrees to notify the Company upon any change in the residence address indicated below.

 EXHIBIT A 

TERMS AND CONDITIONS OF STOCK OPTION GRANT 
 1. Grant of Option. The Company hereby grants to the Participant named in the Notice of Grant (the “Participant”) an option (the “Option”) to purchase the number of Shares, as
set forth in the Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the “Exercise Price”), subject to all of the terms and conditions in this Agreement, the Plan, and the Separate Agreement (as applicable),
which are incorporated herein by reference. Subject to Section 18(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Agreement, the terms and conditions of the Plan will
prevail. 
 (a) The following paragraph applies only if the Participant is a U.S. taxpayer or otherwise subject to U.S.
taxation: The Option will be designated as either an Incentive Stock Option (“ISO”) or a Nonstatutory Stock Option (“NSO”). If designated in the Notice of Grant as an ISO, this Option is intended to qualify as an ISO under
Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). However, if this Option is intended to be an Incentive Stock Option, to the extent that it exceeds the $100,000 rule of Code Section 422(d) it will be
treated as an NSO. Further, if for any reason this Option (or portion thereof) will 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
will 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.

 (b) For non-U.S. taxpayers and Participants not subject to U.S. taxation, the Option will be designated as an NSO.

 2. Vesting Schedule. Except as provided in Section 3, the Option awarded by this Agreement will vest in
accordance with the vesting provisions set forth in the Notice of Grant. Shares scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest in Participant in accordance with any of the provisions of this
Agreement, unless Participant will have been continuously a Service Provider from the Date of Grant until the date such vesting occurs. 
 3. Administrator Discretion. The Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser portion of the balance, of the unvested Option at any time, subject to
the terms of the Plan. If so accelerated, such Option will be considered as having vested as of the date specified by the Administrator. 
 4. Exercise of Option. 
 (a) Right to Exercise. This Option may be
exercised only within the term set out in the Notice of Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Agreement. 

  
 - 4 -

 (b) Method of Exercise. This Option is exercisable by delivery of an exercise notice,
in the form attached as Exhibit C (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which will state the election to exercise the Option, the number of Shares in respect of
which the Option is being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company pursuant to the provisions of the Plan. The Exercise Notice will be completed by Participant and
delivered to the Company. The Exercise Notice will be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares together and of any Tax-Related Items (as defined in Section 6(a)). This Option will be deemed to be
exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price. 
 5.
Method of Payment. Payment of the aggregate Exercise Price will be by any of the following, or a combination thereof, at the election of 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) if Participant is a U.S. employee, surrender of other Shares which have a Fair Market Value on the date of surrender
equal to the aggregate Exercise Price of the Exercised Shares, provided that accepting such Shares, in the sole discretion of the Administrator, will not result in any adverse accounting consequences to the Company. 

6. Tax Obligations. 
 (a) Responsibility for Taxes. Notwithstanding any contrary provision of this Agreement, no certificate representing the Shares will be issued to Participant, unless and until satisfactory
arrangements (as determined by the Administrator) will have been made by Participant with respect to the payment of income, employment, social insurance, National Insurance Contributions, payroll tax, fringe benefit tax, payment on account or other
tax-related items related to Participant’s participation in the Plan and legally applicable to Participant including, without limitation, in connection with the grant, vesting or exercise of the Option, the subsequent sale of Shares acquired
under the Plan and/or the receipt of any dividends on such Shares which the Company determines must be withheld (“Tax-Related Items”). To the extent determined appropriate by the Company in its discretion, it will have the right (but not
the obligation) to satisfy any Tax-Related Items by reducing the number of Shares otherwise deliverable to Participant. If Participant fails to make satisfactory arrangements for the payment of any required Tax-Related Items hereunder at the time of
the Option exercise, Participant acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver the Shares if such amounts are not delivered at the time of exercise. Participant authorizes the Company and/or the
Employer to withhold any Tax-Related Items legally payable by Participant from his or her wages or other cash compensation paid to Participant by the Company and/or the Employer or from proceeds of the sale of Shares. Further, if Participant is
subject to tax in more than one jurisdiction between the Date of Grant and the date of 

  
 - 5 -

 
any relevant taxable or tax withholding event, as applicable, Participant acknowledges and agrees that the Company and/or Participant’s employer (the “Employer”), or former
employer, as applicable, may be required to withhold or account for tax in more than one jurisdiction. Regardless of any action of the Company or the Employer, Participant acknowledges that the ultimate liability for all Tax-Related Items is and
remains Participant’s responsibility and may exceed the amount actually withheld by the Company or the Employer. Participant further acknowledges that the Company and the Employer (1) make no representations or undertakings regarding the
treatment of any Tax-Related Items in connection with any aspect of the Option; and (2) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Option to reduce or eliminate Participant’s
liability for Tax-Related Items or achieve any particular tax result. 
 (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 will 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.” 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
charges to 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 will be solely responsible for
Participant’s costs related to such a determination. 
 7. Rights as Stockholder. Neither Participant nor any person
claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares will have been issued, recorded on
the records of the Company or its transfer agents or registrars, and delivered to Participant. After such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the Company with respect to voting such Shares and
receipt of dividends and distributions on such Shares. 
 8. 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

  
 - 6 -

 
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 WILL 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, SUBJECT TO APPLICABLE LAWS.

 9. Service Acknowledgments. In accepting the Option, Participant acknowledges, understands and agrees that:

 (a) the Plan is established voluntarily by the Company, it is discretionary in nature, and may be amended, suspended or
terminated by the Company at any time, to the extent permitted by the Plan; 
 (b) the grant of the Option is voluntary and
occasional and does not create any contractual or other right to receive future grants of options, or benefits in lieu of options, even if options have been granted in the past; 

(c) all decisions with respect to future option or other grants, if any, will be at the sole discretion of the Company; 

(d) Participant is voluntarily participating in the Plan; 
 (e) the Option and any Shares acquired under the Plan are not intended to replace any pension rights or compensation; 
 (f) the Option and Shares acquired under the Plan and the income and value of same, are not part of normal or expected compensation for purposes of calculating any severance, resignation, termination,
redundancy, dismissal, end-of-service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments; 
 (g) the future value of the Shares underlying the Option is unknown, indeterminable, and cannot be predicted with certainty; 
 (h) if the underlying Shares do not increase in value, the Option will have no value; 
 (i) if Participant exercises the Option and acquires Shares, the value of such Shares may increase or decrease in value, even below the Exercise Price; 

  
 - 7 -

 (j) for purposes of the Option, Participant’s engagement as a Service Provider will be
considered terminated as of the date Participant is no longer actively providing services to the Company or any Parent or Subsidiary (regardless of the reason for such termination and whether or not later found to be invalid or in breach of
employment laws in the jurisdiction where Participant is a Service Provider or the terms of Participant’s engagement agreement, if any), and unless otherwise expressly provided in this Agreement or determined by the Administrator,
(i) Participant’s right to vest in the Option under the Plan, if any, will terminate as of such date and will not be extended by any notice period (e.g., Participant’s period of service would not include any contractual notice
period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Participant is a Service Provider or Participant’s engagement agreement, if any, unless Participant is providing bona
fide services during such time); and (ii) the period (if any) during which Participant may exercise the Option after such termination of Participant’s engagement as a Service Provider will commence on the date Participant ceases to
actively provide services and will not be extended by any notice period mandated under employment laws in the jurisdiction where Participant is employed or terms of Participant’s engagement agreement, if any; the Administrator shall have the
exclusive discretion to determine when Participant is no longer actively providing services for purposes of his or her Option grant (including whether Participant may still be considered to be providing services while on a leave of absence);

 (k) unless otherwise provided in the Plan or by the Company in its discretion, the Option and the benefits evidenced by this
Agreement do not create any entitlement to have the Option or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares; and

 (l) the following provisions apply only if Participant is providing services outside the United States: 

 

	 	(i)	the Option and the Shares subject to the Option are not part of normal or expected compensation or salary for any purpose; 

 

	 	(ii)	Participant acknowledges and agrees that none of the Company, the Employer, or any Parent or Subsidiary shall be liable for any foreign exchange rate fluctuation
between Participant’s local currency and the United States Dollar that may affect the value of the Option or of any amounts due to Participant pursuant to the exercise of the Option or the subsequent sale of any Shares acquired upon exercise;
and 

  

	 	(iii)	 no claim or entitlement to compensation or damages shall arise from forfeiture of the Option resulting from the termination of Participant’s
engagement as a Service Provider (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is a Service Provider or the terms of Participant’s engagement
agreement, if any), and in consideration of the grant of the Option to which Participant is otherwise not entitled, Participant irrevocably agrees never to institute any claim against the

  
 - 8 -

	 	
Company, any Parent, any Subsidiary or the Employer, waives his or her ability, if any, to bring any such claim, and releases the Company, any Subsidiary and the Employer from any such claim; if,
notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by participating in the Plan, Participant shall be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all
documents necessary to request dismissal or withdrawal of such claim. 

 10. No Advice Regarding Grant. The
Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations or assessments regarding Participant’s participation in the Plan, or Participant’s acquisition or sale of the underlying Shares.
Participant is hereby advised to consult with his or her own personal tax, legal and financial advisors regarding his or her participation in the Plan before taking any action related to the Plan. 

11. Data Privacy. Participant understands that the Company and the Employer
may collect, where permissible under applicable law, certain personal information about Participant, including, but not limited to, Participant’s name, home address and telephone number, date of birth, social insurance number or other
identification number, salary, nationality, job title, any shares of stock or directorships held in the Company, details of all Options or any other entitlement to stock awarded, canceled, exercised, vested, unvested or outstanding in
Participant’s favor (“Data”), for the exclusive purpose of implementing, administering and managing the Plan. Participant understands that Company may transfer Participant’s Data to the United States, which is not considered
by the European Commission to have data protection laws equivalent to the laws in Participant’s country. The Company therefore maintains an EU-US Safe Harbor certification to protect any data consistent with data protection laws of the EU.
Participant understands that the Company will transfer Participant’s Data to a stock plan service provider as may be selected by the Company in the future, which is assisting the Company with the implementation, administration and management of
the Plan. Participant understands that the recipients of the Data may be located in the United States or elsewhere, and that the recipient’s country (e.g., the United States) may have different data privacy laws that the European Commission or
Participant’s jurisdiction does not consider to be equivalent to the protections in Participant’s country. Participant understands that if he or she resides outside the United States, he or she may request a list with the names and
addresses of any potential recipients of the Data by contacting his or her local human resources representative. Participant authorizes the Company and any other possible recipients which may assist the Company with implementing, administering and
managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purposes of implementing, administering and managing Participant’s participation in the Plan. Participant understands that Data
will be held only as long as is necessary to implement, administer and manage Participant’s participation in the Plan. Participant understands that if he or she resides outside the United States, he or she may, at any time, view Data, request
additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing his or her local human resources representative.
Further, Participant understands that he or she is providing the consents herein on a purely voluntary 

  
 - 9 -

 
basis. If Participant does not consent, or if Participant later seeks to revoke his or her consent, his or her engagement as a Service Provider and career with the Employer will not be adversely
affected; the only adverse consequence of refusing or withdrawing Participant’s consent is that the Company would not be able to grant Participant Options or other equity awards or administer or maintain such awards. Therefore, Participant
understands that refusing or withdrawing his or her consent may affect Participant’s ability to participate in the Plan. For more information on the consequences of Participant’s refusal to consent or withdrawal of consent, Participant
understands that he or she may contact his or her local human resources representative. Participant understands that Participant has the right to access, and to request a copy of, the Data held about Participant. Participant also understands that
Participant has the right to discontinue the collection, processing, or use of Participant’s Data, or supplement, correct, or request deletion of any of Participant’s Data. To exercise Participant’s rights, Participant may contact
Participant’s local human resources representative. Participant hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of Participant’s personal data as described in this Agreement
and any other Option grant materials by and among, as applicable, the Employer, the Company and any Parent or Subsidiary for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. Participant
understands that Participant’s consent will be sought and obtained for any processing or transfer of Particpant’s Data for any purpose other than as described in the Agreement and any other Plan materials. 

12. Address for Notices. Any notice to be given to the Company under the terms of this Agreement will be addressed to the Company
at Twitter, Inc., 1355 Market Street, Suite 900, San Francisco, CA 94103, or at such other address as the Company may hereafter designate in writing.

Participant only by Participant.

contained herein, this Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto. 
 15. Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion, that the listing, registration, qualification or rule compliance of the Shares upon any
securities exchange or under any state, federal or foreign law, the tax code and related regulations or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the purchase by, or issuance of
Shares to, Participant (or his or her estate) hereunder, such purchase or issuance will not occur unless and until such listing, registration, qualification, rule compliance, consent or approval will have been completed, effected or obtained free of
any conditions not acceptable to the Company. The Company will make all reasonable efforts to meet the requirements of any such state, federal or foreign law or securities exchange and to obtain any such consent or approval of any such governmental
authority or securities exchange. Assuming such compliance, for income tax purposes the Exercised Shares will be considered transferred to Participant on the date the Option is exercised with respect to such Exercised Shares.

 18. Electronic Delivery and Acceptance. The Company may, in its sole discretion, decide to deliver any documents related to Options awarded under the Plan or future options that may be awarded

 21. Agreement Severable. In the event that any provision in this Agreement will be held invalid or unenforceable, such
provision will be severable from, and such invalidity or unenforceability will not be construed to have any effect on, the remaining provisions of this Agreement.

 Participant understands that the Company has unilaterally,
gratuitously, and in its sole discretion decided to grant Options under the Plan to individuals who may be employees of the Company or one of its Subsidiaries or affiliates throughout the world. The decision is a limited decision that is entered

Notifications 
 Tax

 UNITED KINGDOM 
 Terms and Conditions 

Tax Reporting and Payment Liability. The following provision supplements Exhibit A, Section 6(a) (Responsibility for Taxes) of the
Award Agreement: 
 Participant agrees that the Company or the Employer may calculate the Tax-Related Items to be withheld and accounted for by
reference to the maximum applicable rates, without prejudice to any right participant may have to recover any overpayment from relevant U.K. tax authorities. If payment or withholding of any income tax liability arising in connection with
participant’s participation in the Plan is not made by participant to the Employer within ninety (90) days of the event giving rise to such income tax liability or such other period specified in Section 222(1)(c) of the U.K. Income
Tax (Earnings and Pensions) Act 2003 (the “Due Date”), Participant understands and agrees that the amount of any uncollected income tax will constitute a loan owed by participant to the Employer, effective on the Due Date. Participant
understands and agrees that the loan will bear interest at the then-current official rate of Her Majesty’s Revenue and Customs, it will be immediately due and repayable by participant, and the Company and/or the Employer may recover it at any
time thereafter by any of the means referred to in the Plan and/or this Award Agreement. Notwithstanding the foregoing, participant understands and agrees that if he or she is a director or an executive officer of the Company (within the meaning of
such terms for purposes of Section 13(k) of the Exchange Act), he or she will not be eligible for such a loan to cover the income tax liability. In the event that participant is a director or executive officer and the income tax is not
collected from or paid by participant by the Due Date, Participant understands that the amount of any uncollected income tax will constitute an additional benefit to participant on which additional income tax and National Insurance Contributions
will be payable. Participant understands and agrees that he or she will be responsible for reporting and paying any income tax due on this additional benefit directly to Her Majesty’s Revenue and Customs under the self-assessment regime and for
reimbursing the Company or the Employer (as appropriate) for the value of any primary and (to the extent legally possible) secondary class 1 national insurance contributions due on this additional benefit which the Company or the Employer may
recover from participant by any of the means referred to in the Plan and/or this Award Agreement. 
 Notwithstanding the foregoing, if
Participant is an executive officer or director (as within the meaning of Section 13(k) of the U.S. Securities and Exchange Act of 1934, as amended), the terms of the provision above will not apply. In the event that Participant is an executive
office or director and income tax is not collected from or paid by Participant by the Due Date, the amount of any uncollected income tax will constitute a benefit to Participant on which additional income tax and National Insurance Contributions
(“NICs”) (including Employer’s NICs, as defined below) may be 

  
 - 21 -

 
payable. Participant understands that he or she will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and
for reimbursing the Company and/or the Employer (as appropriate) for the value of any NICs due on this additional benefit. 
 Joint
Election. 
 Tax-Related Items, as defined in Exhibit A, Section 7 shall include Primary and to the extent legally possible
Secondary Class 1 National Insurance Contributions. 
 As a necessary condition of participation in the Plan, Participant agrees to accept any
liability for all secondary Class 1 NICs which may be payable by the Company and/or the Parent or Subsidiary employing or retaining Participant in connection with the Options and any event giving rise to Tax-Related Items (the “Employer’s
NICs”). Without limitation to the foregoing, Participant agrees to enter into a joint election with the Company (the “Joint Election”), the form of such Joint Election being formally approved by HMRC, and to execute any other consents
or elections required to accomplish the transfer of the entirety of Employer’s NICs to the employee. Participant further agrees to execute such other joint elections as may be required between Participant and any successor to the Company and/or
the Parent or Subsidiary employing or retaining Participant. Participant further agrees that the Company and/or the Parent or Subsidiary employing or retaining Participant may collect the Employer’s NICs from him or her by any of the means set
forth in Exhibit A, Section 6 of the Award Agreement. 
 If Participant does not enter into a Joint Election, if approval of the Joint
Election has been withdrawn by HMRC or if such Joint Election is jointly revoked by Participant and the Company or the Parent or Subsidiary employing or retaining Participant, as applicable, the Company, in its sole discretion and without any
liability to the Company or the Parent or Subsidiary employing or retaining Participant, may choose not to issue or deliver any Shares to the employee upon exercise of the Options.

 2013 EQUITY INCENTIVE PLAN 
 RESTRICTED STOCK UNIT AGREEMENT

 Unless otherwise defined herein, the terms defined in the Twitter, Inc. 2013 Equity Incentive Plan (the “Plan”)
will have the same defined meanings in this Restricted Stock Unit Agreement (the “Award Agreement”), which includes the Notice of Restricted Stock Unit Grant (the “Notice of Grant”) and Terms and Conditions of Restricted Stock
Unit Grant, attached hereto as Exhibit A. 
 NOTICE OF RESTRICTED STOCK UNIT GRANT 

Participant Name: 
 Address: 
 Participant has been granted the right to receive an Award of
Restricted Stock Units, subject to the terms and conditions of the Plan and this Award Agreement, as follows: 
  

					
	Grant Number	 	  
	  	
			
	Date of Grant	 	  
	  	
			
	Vesting Commencement Date	 	  
	  	
			
	Number of Restricted Stock Units	 	  
	  	

 Vesting Schedule: 
 Subject to any acceleration provisions contained in the Plan or set forth below, the Restricted Stock Units will vest in accordance with the following schedule: 

[Twenty-five percent (25%) of the Restricted Stock Units will vest on the one (1) year anniversary of the Vesting
Commencement Date, and one-sixteenth (1/16th) of the Restricted Stock Units will vest each quarter thereafter on the same day as the Vesting Commencement Date, subject to Participant continuing to be a Service Provider through each such
date.] 
 Notwithstanding the foregoing, the vesting of the Restricted Stock Units shall be subject to any vesting
acceleration provisions applicable to these Restricted Stock Units contained in the Plan and/or any employment or service agreement, offer letter, change in control severance agreement or policy, or any other agreement or policy that, prior to
and effective as of the date of this Agreement, has been entered into or agreed upon, as the case may be, between Participant and the Company or any parent or subsidiary corporation of the Company (such agreement or policy, a “Separate
Agreement”) to the extent not otherwise duplicative of the vesting terms described above (by way of example, if a Separate Agreement provides for different acceleration of vesting provisions for all of Participant’s Restricted Stock
Units upon a termination of Participant as a Service Provider for “good reason” that is defined differently, and the 

 
Participant’s status as a Service Provider terminates in a manner that would trigger “good reason” under the Separate Agreement but not under this Agreement, the Participant would
remain entitled to the acceleration of vesting under the Separate Agreement). 
 In the event Participant ceases to be a Service
Provider for any or no reason before Participant vests in the Restricted Stock Units, the Restricted Stock Units and Participant’s right to acquire any Shares hereunder will immediately terminate, subject to Applicable Laws. 

By Participant’s signature and the signature of the representative of Twitter, Inc. (the “Company”) below, Participant and
the Company agree that this Award of Restricted Stock Units is granted under and governed by the terms and conditions of the Plan and this Award Agreement, including the Terms and Conditions of Restricted Stock Unit Grant, attached hereto as

 EXHIBIT A 

TERMS AND CONDITIONS OF RESTRICTED STOCK UNIT GRANT 
 1. Grant. The Company hereby grants to the individual named in the Notice of Grant (the “Participant”) under the Plan an Award of Restricted Stock Units, subject to all of the terms and
conditions in this Award Agreement, the Plan, and the Separate Agreement (as applicable), which are incorporated herein by reference. Subject to Section 18(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan
and the terms and conditions of this Award Agreement, the terms and conditions of the Plan will prevail. 
 2. Company’s
Obligation to Pay. Each Restricted Stock Unit represents the right to receive a Share on the date it vests. Unless and until the Restricted Stock Units will have vested in the manner set forth in Sections 3 or 4, Participant will have no
right to payment of any such Restricted Stock Units. Prior to actual payment of any vested Restricted Stock Units, such Restricted Stock Units will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of
the Company. Any Restricted Stock Units that vest in accordance with Sections 3 or 4 will be paid to Participant (or in the event of Participant’s death, to his or her estate) in whole Shares, subject to Participant satisfying any obligations
for Tax-Related Items (as defined in Section 7). Subject to the provisions of Section 4, such vested Restricted Stock Units shall be paid in whole Shares as soon as practicable after vesting, but in each such case within the period sixty
(60) days following the vesting date. In no event will Participant be permitted, directly or indirectly, to specify the taxable year of the payment of any Restricted Stock Units payable under this Award Agreement. 

3. Vesting Schedule. Except as provided in Section 4, and subject to Section 5, the Restricted Stock Units awarded by
this Award Agreement will vest in accordance with the vesting provisions set forth in the Notice of Grant. Restricted Stock Units scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest in Participant in
accordance with any of the provisions of this Award Agreement, unless Participant will have been continuously a Service Provider from the Date of Grant until the date such vesting occurs. 

4. Administrator Discretion. The Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser
portion of the balance, of the unvested Restricted Stock Units at any time, subject to the terms of the Plan. If so accelerated, such Restricted Stock Units will be considered as having vested as of the date specified by the Administrator. The
payment of Shares vesting pursuant to this Section 4 shall in all cases be paid at a time or in a manner that is exempt from, or complies with, Section 409A. 
 The following paragraphs in this Section 4 apply only if the Participant is a U.S. taxpayer or otherwise subject to U.S. taxation: Notwithstanding anything in the Plan or this Award Agreement
to the contrary, if the vesting of the balance, or some lesser portion of the balance, of the Restricted Stock Units is accelerated in connection with Participant’s termination as a Service Provider (provided that such termination is a
“separation from service” within the meaning of Section 409A, as determined by the Company), other than due to death, and if (x) Participant is a “specified employee” within the meaning of Section 409A at
the time of such termination as a Service Provider and (y) the payment of such accelerated Restricted Stock Units 

  
 -3-

 
will result in the imposition of additional tax under Section 409A if paid to Participant on or within the six (6) month period following Participant’s termination as a Service
Provider, then the payment of such accelerated Restricted Stock Units will not be made until the date six (6) months and one (1) day following the date of Participant’s termination as a Service Provider, unless Participant dies
following his or her termination as a Service Provider, in which case, the Restricted Stock Units will be paid in Shares to Participant’s estate as soon as practicable following his or her death. It is the intent of this Award Agreement that it
and all payments and benefits hereunder be exempt from, or comply with, the requirements of Section 409A so that none of the Restricted Stock Units provided under this Award Agreement or Shares issuable thereunder will be subject to the
additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to be so exempt or so comply. Each payment payable under this Award Agreement is intended to constitute a separate payment for purposes of Treasury
Regulation Section 1.409A-2(b)(2). For purposes of this Award Agreement, “Section 409A” means Section 409A of the Code, and any final Treasury Regulations and Internal Revenue Service guidance thereunder, as each may be amended
from time to time. 
 5. Forfeiture upon Termination of Status as a Service Provider. Notwithstanding any contrary
provision of this Award Agreement, the balance of the Restricted Stock Units that have not vested as of the time of Participant’s termination as a Service Provider for any or no reason and Participant’s right to acquire any Shares
hereunder will immediately terminate, subject to Applicable Laws. The date of Participant’s termination as a Service Provider is detailed in Section 10(h). 
 6. Death of Participant. Any distribution or delivery to be made to Participant under this Award Agreement will, if Participant is then deceased, be made to Participant’s designated
beneficiary, or if no beneficiary survives Participant, the administrator or executor of Participant’s estate. Any such transferee must furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence
satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations pertaining to said transfer. 
 7. Responsibility for Taxes. Notwithstanding any contrary provision of this Award Agreement, no certificate representing the Shares will be issued to Participant, unless and until satisfactory
arrangements (as determined by the Administrator) will have been made by Participant with respect to the payment of income, employment, social insurance, National Insurance Contributions, payroll tax, fringe benefit tax, payment on account or other
tax-related items related to Participant’s participation in the Plan and legally applicable to Participant, including, but not limited to, the grant, vesting or settlement of the Restricted Stock Units, the subsequent sale of Shares acquired
pursuant to such settlement and the receipt of any dividends (“Tax-Related Items”) which the Company determines must be withheld with respect to such Shares. Prior to vesting and/or settlement of the Restricted Stock Units, Participant
will pay or make adequate arrangements satisfactory to the Company and/or Participant’s employer (the “Employer”) to satisfy all withholding and payment obligations of Tax-Related Items of the Company and/or the Employer. In this
regard, Participant authorizes the Company and/or the Employer to withhold any Tax-Related Items legally payable by Participant from his or her wages or other cash compensation paid to Participant by the Company and/or the Employer or from proceeds
of the sale of Shares. Alternatively, or in addition, if permissible under applicable local law, the Administrator, in its sole discretion and pursuant to such procedures as it may 

  
 -4-

 
specify from time to time, may permit or require Participant to satisfy such tax withholding obligation, in whole or in part (without limitation) by (a) paying cash, (b) electing to
have the Company withhold otherwise deliverable Shares having a Fair Market Value equal to the minimum amount required to be withheld, (c) selling a sufficient number of such Shares otherwise deliverable to Participant through such means as the
Company may determine in its sole discretion (whether through a broker or otherwise) equal to the amount required to be withheld, or (d) if Participant is a U.S. employee, delivering to the Company already vested and owned Shares having a Fair
Market Value equal to the amount required to be withheld. To the extent determined appropriate by the Company in its discretion, it will have the right (but not the obligation) to satisfy any obligations for Tax-Related Items by reducing the number
of Shares otherwise deliverable to Participant [and, until determined otherwise by the Company, this will be the method by which such tax withholding obligations are satisfied]. Further, if Participant is subject to tax in more than one jurisdiction
between the Date of Grant and a date of any relevant taxable or tax withholding event, as applicable, Participant acknowledges and agrees that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account
for tax in more than one jurisdiction. If Participant fails to make satisfactory arrangements for the payment of any Tax-Related Items hereunder at the time any applicable Restricted Stock Units otherwise are scheduled to vest pursuant to Sections 3
or 4 or Tax-Related Items related to Restricted Stock Units otherwise are due, Participant will permanently forfeit such Restricted Stock Units and any right to receive Shares thereunder and the Restricted Stock Units will be returned to the Company
at no cost to the Company. Regardless of any action of the Company or the Employer, Participant acknowledges that the ultimate liability for all Tax-Related Items is and remains Participant’s responsibility and may exceed the amount actually
withheld by the Company or the Employer. Participant further acknowledges that the Company and the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the
Restricted Stock Units; and (2) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Restricted Stock Units to reduce or eliminate Participant’s liability for Tax-Related Items or achieve
any particular tax result. 
 8. Rights as Stockholder. Neither Participant nor any person claiming under or through
Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares will have been issued, recorded on the records of the Company
or its transfer agents or registrars, and delivered to Participant. After such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the Company with respect to voting such Shares and receipt of dividends and
distributions on such Shares. 
 9. No Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE
VESTING OF THE RESTRICTED STOCK UNITS 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 AWARD OF RESTRICTED STOCK UNITS OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AWARD AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET

  
 -5-

 
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 WILL 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, SUBJECT TO APPLICABLE
LAWS. 
 10. Nature of Grant. In accepting the grant, Participant acknowledges, understands and agrees that: 

 

	 	(a)	the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time,
to the extent permitted by the Plan; 

  

	 	(b)	the grant of the Restricted Stock Units is voluntary and occasional and does not create any contractual or other right to receive future grants of Restricted Stock
Units, or benefits in lieu of Restricted Stock Units, even if Restricted Stock Units have been granted in the past; 

  

	 	(c)	all decisions with respect to future Restricted Stock Units or other grants, if any, will be at the sole discretion of the Company; 

 

	 	(d)	Participant is voluntarily participating in the Plan; 

  

	 	(e)	the Restricted Stock Units and the Shares subject to the Restricted Stock Units are not intended to replace any pension rights or compensation;

  

	 	(f)	the Restricted Stock Units and the Shares subject to the Restricted Stock Units, and the income and value of same, are not part of normal or expected compensation for
purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments; 

 

	 	(g)	the future value of the underlying Shares is unknown, indeterminable and cannot be predicted with certainty; 

 

	 	(h)	 for purposes of the Restricted Stock Units, Participant’s status as a Service Provider will be considered terminated as of the date Participant is
no longer actively providing services to the Company or any Parent or Subsidiary (regardless of the reason for such termination and whether or not later to be found invalid or in breach of employment laws in the jurisdiction where Participant is a
Service Provider or the terms of Participant’s service agreement, if any), and unless otherwise expressly provided in this Award Agreement or determined by the Administrator, Participant’s right to vest in the Restricted Stock Units under
the Plan, if any, will terminate as of such date and will not be extended by any notice period (e.g., Participant’s period of service would not include any contractual notice period or any period of “garden leave” or similar
period 

  
 -6-

	 	
mandated under employment laws in the jurisdiction where Participant is a Service Provider or the terms of Participant’s service agreement, if any, unless Participant is providing bona fide
services during such time); the Administrator shall have the exclusive discretion to determine when Participant is no longer actively providing services for purposes of the Restricted Stock Units grant (including whether Participant may still be
considered to be providing services while on a leave of absence); 

  

	 	(i)	unless otherwise provided in the Plan or by the Company in its discretion, the Restricted Stock Units and the benefits evidenced by this Award Agreement do not create
any entitlement to have the Restricted Stock Units or any such benefits transferred to, or assumed by, another company nor be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the Shares; and

  

	 	(j)	the following provisions apply only if Participant is providing services outside the United States: 

 

	 	i.	the Restricted Stock Units and the Shares subject to the Restricted Stock Units are not part of normal or expected compensation or salary for any purpose;

  

	 	ii.	Participant acknowledges and agrees that none of the Company, the Employer, or any Parent or Subsidiary shall be liable for any foreign exchange rate fluctuation
between Participant’s local currency and the United States Dollar that may affect the value of the Restricted Stock Units or of any amounts due to Participant pursuant to the settlement of the Restricted Stock Units or the subsequent sale of
any Shares acquired upon settlement; and 

  

	 	iii.	no claim or entitlement to compensation or damages shall arise from forfeiture of the Restricted Stock Units resulting from the termination of Participant’s status
as a Service Provider (for any reason whatsoever whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is a Service Provider or the terms of Participant’s service agreement, if any), and
in consideration of the grant of the Restricted Stock Units to which Participant is otherwise not entitled, Participant irrevocably agrees never to institute any claim against the Company, any Subsidiary or the Employer, waives his or her
ability, if any, to bring any such claim, and releases the Company, any Parent, any Subsidiary and the Employer from any such claim; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by
participating in the Plan, Participant shall be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or withdrawal of such claim. 

  
 -7-

 11. No Advice Regarding Grant. The Company is not providing any tax, legal or
financial advice, nor is the Company making any recommendations or assessments regarding Participant’s participation in the Plan, or Participant’s acquisition or sale of the underlying Shares. Participant is hereby advised to consult with
his or her own personal tax, legal and financial advisors regarding his or her participation in the Plan before taking any action related to the Plan. 
 12. Data Privacy. Participant understands that the Company and the Employer may collect, where permissible under Applicable Law certain personal
information about Participant, including, but not limited to, Participant’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any Shares or
directorships held in the Company, details of all Restricted Stock Units granted under the Plan or any other entitlement to Shares awarded, canceled, vested, unvested or outstanding in Participant’s favor (“Data”), for the exclusive
purpose of implementing, administering and managing the Plan. Participant understands that Company may transfer Participant’s Data to the United States, which is not considered by the European Commission to have data protection laws equivalent
to the laws in Participant’s country. The Company therefore maintains an EU-US Safe Harbor certification to protect Participant’s data consistent with data protection laws of the EU.  

Participant understands that the Company will transfer Participant’s Data to its designated broker, or such other stock plan service provider as
may be selected by the Company in the future, which is assisting the Company with the implementation, administration and management of the Plan. Participant understands that the recipients of the Data may be located in the United States or
elsewhere, and that a recipient’s country of operation (e.g., the United States) may have different data privacy laws that the European Commission or Participant’s jurisdiction does not consider to be equivalent to the protections in
Participant’s country. Participant understands that Participant may request a list with the names and addresses of any potential recipients of the Data by contacting Participant’s local human resources representative. Participant
authorizes the Company, the Company’s designated broker and any other possible recipients which may assist the Company with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic
or other form, for the sole purpose of implementing, administering and managing Participant’s participation in the Plan. Participant understands that Data will be held only as long as is necessary to implement, administer and manage
Participant’s participation in the Plan. Participant understands that Participant may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or
withdraw the consents herein, in any case without cost, by contacting in writing Participant’s local human resources representative. Further, Participant understands that Participant is providing the consents herein on a purely voluntary basis.
If Participant does not consent, or if Participant later seeks to revoke Participant’s consent, Participant’s employment status or career with the Company or the Employer will not be adversely affected; the only adverse consequence of
refusing or withdrawing Participant’s consent is that the Company would not be able to grant Participant Restricted Stock Units under the Plan or other equity awards, or administer or maintain such awards. Therefore, Participant understands
that refusing or withdrawing Participant’s consent may affect Participant’s ability to participate in the Plan. For more information on the consequences of Participant’s refusal to consent or withdrawal of consent, Participant
understands that Participant may contact Participant’s local human resources representative. 

  
 -8-

 Participant understands that Participant has the right to access, and to request a copy of, the Data held
about Participant. Participant also understands that Participant has the right to discontinue the collection, processing, or use of Participant’s Data, or supplement, correct, or request deletion of Participant’s Data. To exercise
Participant’s rights, Participant may contact Participant’s local human resources representative. 
 Participant hereby
explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of Participant’s personal data as described in the Award Agreement and any other Plan materials by and among, as applicable, the Employer,
the Company and its Parents, Subsidiaries and affiliates for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. Participant understands that Participant’s consent will be sought and
obtained for any processing or transfer of Participant’s data for any purpose other than as described in the Award Agreement and any other plan materials. 
 13. Address for Notices. Any notice to be given to the Company under the terms of this Award Agreement will be addressed to the Company at Twitter, Inc., 1355 Market Street, Suite 900, San
Francisco, CA 94103, or at such other address as the Company may hereafter designate in writing. 
 14. Grant is Not
Transferable. Except to the limited extent provided in Section 6, this grant and the rights and privileges conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and
will not be subject to sale under execution, attachment or similar process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this grant, or any right or privilege conferred hereby, or upon any attempted sale under
any execution, attachment or similar process, this grant and the rights and privileges conferred hereby immediately will become null and void. 
 15. Binding Agreement. Subject to the limitation on the transferability of this grant contained herein, this Award Agreement will be binding upon and inure to the benefit of the heirs, legatees,
legal representatives, successors and assigns of the parties hereto. 
 16. Additional Conditions to Issuance of Stock.
If at any time the Company will determine, in its discretion, that the listing, registration, qualification or rule compliance of the Shares upon any securities exchange or under any state, federal or foreign law, the tax code and related
regulations or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of Shares to Participant (or his or her estate) hereunder, such issuance will not occur unless and until such
listing, registration, qualification, rule compliance, consent or approval will have been completed, effected or obtained free of any conditions not acceptable to the Company. Where the Company determines that the delivery of the payment of any
Shares will violate federal securities laws or other applicable laws, the Company will defer delivery until the earliest date at which the Company reasonably anticipates that the delivery of Shares will no longer cause such violation. The Company
will make all reasonable efforts to meet the requirements of any such state, federal or foreign law or securities exchange and to obtain any such consent or approval of any such governmental authority or securities exchange.

interested persons. No member of the Administrator will be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or this Award Agreement.

delivery specified by the Company. Participant consents to the electronic delivery of the Plan and this Award Agreement. Participant acknowledges that he or she may receive from the Company a paper copy of any documents delivered electronically at
no cost to Participant by contacting the Company by telephone or in writing. Participant further acknowledges that Participant will be provided with a paper copy of any documents if the attempted electronic delivery of such documents fails.
Similarly, Participant understands that Participant must provide the Company or any designated third party administrator with a paper copy of any documents if the attempted electronic delivery of such documents fails. Participant may revoke his or
her consent to the electronic delivery of documents or may change the electronic mail address to which such documents are to be delivered (if Participant has provided an electronic mail address) at any time by notifying the Company of such revoked
consent or revised e-mail address by telephone, postal service or electronic mail. Finally, Participant understands that he or she is not required to consent to electronic delivery of documents. 

20. Language. If Participant has received this Award Agreement or any other document related to the Plan translated into a
language other than English and if the meaning of the translated version is different than the English version, the English version will control, subject to Applicable Laws.

23. Amendment, Suspension or Termination of the Plan. By accepting this Award, Participant expressly warrants that he or she has
received an Award of Restricted Stock Units under the Plan, and has received, read and understood a description of the Plan. Participant understands that the Plan is discretionary in nature and may be amended, suspended or terminated by the Company

processing activity, including the transfer of Participant’s personal data abroad, outside of the European Union, as herein specified and pursuant to applicable laws and regulations, does not require Participant’s consent thereto as the

 UNITED KINGDOM 
 Terms and Conditions 
 Tax Reporting and Payment Liability. The
following provision supplements Exhibit A, Section 7 (Responsibility for Taxes) of the Award Agreement: 
 Participant agrees that the
Company or the Employer may calculate the Tax-Related Items to be withheld and accounted for by reference to the maximum applicable rates, without prejudice to any right Participant may have to recover any overpayment from relevant U.K. tax
authorities. If payment or withholding of any income tax liability arising in connection with Participant’s participation in the Plan is not made by Participant to the Employer within ninety (90) days of the event giving rise to such
income tax liability or such other period specified in Section 222(1)(c) of the U.K. Income Tax (Earnings and Pensions) Act 2003 (the “Due Date”), Participant understands and agrees that the amount of any uncollected income tax will
constitute a loan owed by the Participant to the Employer, effective on the Due Date. Participant understands and agrees that the loan will bear interest at the then-current official rate of Her Majesty’s Revenue and Customs, it will be
immediately due and repayable by the Participant, and the Company and/or the Employer may recover it at any time thereafter by any of the means referred to in the Plan and/or this Award Agreement. Notwithstanding the foregoing, Participant
understands and agrees that if he or she is a director or an executive officer of the Company (within the meaning of such terms for purposes of Section 13(k) of the Exchange Act), he or she will not be eligible for such a loan to cover the
income tax liability. In the event that Participant is a director or executive officer and the income tax is not collected from or paid by the Participant by the Due Date, Participant understands that the amount of any uncollected income tax will
constitute an additional benefit to Participant on which additional income tax and National Insurance Contributions will be payable. Participant understands and agrees that he or she will be responsible for reporting and paying any income tax due on
this additional benefit directly to Her Majesty’s Revenue and Customs under the self-assessment regime and for reimbursing the Company or the Employer (as appropriate) for the value of any primary and (to the extent legally possible) secondary
class 1 national insurance contributions due on this additional benefit which the Company or the Employer may recover from the Participant by any of the means referred to in the Plan and/or this Award Agreement. 

Notwithstanding the foregoing, if Participant is an executive officer or director (as within the meaning of Section 13(k) of the U.S. Securities and
Exchange Act of 1934, as amended), the terms of the provision above will not apply. In the event that Participant is an executive office or director and income tax is not collected from or paid by Participant by the Due Date, the amount of any
uncollected income tax will constitute a benefit to Participant on which additional income tax and National Insurance Contributions (“NICs”) (including Employer’s NICs, as defined below) may be payable. Participant understands that he
or she will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for reimbursing the Company and/or the Employer (as appropriate) for the value of any NICs due on
this additional benefit.

Participant agrees to enter into a joint election with the Company (the “Joint Election”), the form of such Joint Election being formally approved by HMRC, and to execute any other consents or elections required to accomplish the transfer
