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 .

(i)    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.

(ii)    Subject to Section 15 of the Plan, the following limitations will apply to grants of Options:

(1)    No Service Provider will be granted, in any Fiscal Year, Options to purchase more than 2,000,000 Shares.

(2)    In connection with his or her initial service, a Service Provider may be granted Options to purchase up to an additional 1,000,000 Shares that will not be counted against the limit set forth in subsection (1) above.

(3)    The foregoing limitations will be adjusted proportionately in connection with any change in the Company’s capitalization, as described in Section 15 of the Plan.

(4)    If an Option is cancelled in the same Fiscal Year in which it was granted (other than in connection with a transaction described in Section 15 of the Plan), the cancelled Option will be counted against the limits set forth in subsections (1) and (2) above. For this purpose, if the exercise price of an Option is reduced, the transaction will be treated as a cancellation of the Option and the grant of a new Option.

(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, Code Section 424(a).

(ii)     Waiting Period and Exercise Dates . At the time an Option is granted, the Administrator will fix the period within which the Option may be exercised and will determine any conditions that must be satisfied before the Option may be exercised.

(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.

-9-

(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 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 15 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, but in no event later than the expiration of the term of such Option as set forth in the Award Agreement. 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, but in no event later than the expiration of the term of such Option as set forth in the Award Agreement. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not

-10-

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 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, but in no event later than the expiration of the term of such Option as set forth in the Award Agreement. 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 subsection 6(d) is prevented by the provisions of Section 22 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, provided that during any Fiscal Year no Participant will receive more than an aggregate of 1,000,000 Shares of Restricted Stock, subject to Section 15 of the Plan. Notwithstanding the foregoing limitation, in connection with a Participant’s initial service as an Employee, an Employee may be granted an aggregate of up to an additional 1,000,000 Shares of Restricted Stock.

(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.

(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 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.

(i)     Section 162(m) Performance Restrictions . For purposes of qualifying grants of Restricted Stock as “performance-based compensation” under Code Section 162(m), the Administrator, in its discretion, may set restrictions based upon the achievement of Performance Goals. The Performance Goals will be set by the Administrator on or before the Determination Date. In granting Restricted Stock that is intended to qualify under Code Section 162(m), the Administrator will follow any procedures determined by it from time to time to be necessary or appropriate to ensure qualification of the Award under Code Section 162(m) (e.g., in determining the Performance Goals).

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, provided that during any Fiscal Year no Participant will receive Restricted Stock Units covering more than 1,000,000 Shares, subject to Section 15 of the Plan. Notwithstanding the foregoing limitation, in connection with a Participant’s initial service as an Employee, an Employee may be granted Restricted Stock Units covering up to an additional 1,000,000 Shares. 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 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 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.

(g)     Section 162(m) Performance Restrictions . For purposes of qualifying grants of Performance Units/Shares as “performance-based compensation” under Code Section 162(m), the Administrator, in its discretion, may set restrictions based upon the achievement of Performance Goals. The Performance Goals will be set by the Administrator on or before the Determination Date. In granting Performance Units/Shares which are intended to qualify under Code Section 162(m), the Administrator will follow any procedures determined by it from time to time to be necessary or appropriate to ensure qualification of the Award under Code Section 162(m) (e.g., in determining the Performance Goals).

11.     Performance-Based Compensation Under Code Section 162(m) .

(a)     General . If the Administrator, in its discretion, decides to grant an Award intended to qualify as “performance-based compensation” under Code Section 162(m), the provisions of this Section 11 will control over any contrary provision in the Plan; provided, however, that the Administrator may in its discretion grant Awards that are not intended to qualify as “performance-based compensation” under Code Section 162(m) to such Participants that are based on Performance Goals or other specific criteria or goals but that do not satisfy the requirements of this Section 11.

(b)     Performance Goals . The granting and/or vesting of Awards of Restricted Stock, Restricted Stock Units, Performance Shares and Performance Units and other incentives under the Plan may be made subject to the attainment of performance goals relating to one or more business criteria within the meaning of Code Section 162(m) and may provide for a targeted level or levels of achievement (“ Performance Goals ”) including (i) cash flow (including operating cash flow or free cash flow), (ii) cash position, (iii) revenue (on an absolute basis or adjusted for currency effects), (iv) revenue growth, (v) contribution margin, (vi) gross margin, (vii) operating margin, (viii) operating expenses or operating expenses as a percentage of revenue, (ix) earnings (which may include earnings before interest, taxes, depreciation and amortization, earnings before taxes and net earnings), (x) earnings per share, (xi) operating income, (xii) net income, (xiii) stock price, (xiv) return on equity, (xv) total stockholder return, (xvi) growth in stockholder value relative to a specified publicly reported index (such as the S&P 500 Index), (xvii) return on capital, (xviii) return on assets or net assets, (xix) return on investment, (xx) economic value added, (xxi) operating profit or net operating profit, (xxii) market share, (xxiii) contract awards or backlog, (xxiv) overhead or other expense reduction, (xxv) credit rating, (xxvi) objective customer indicators, (xxvii) new product invention or innovation, (xxviii) attainment of research and development milestones, (xxix) improvements in productivity, (xxx) attainment of objective operating goals, and (xxxi) objective employee metrics. Any Performance Goals may be used to measure the performance of the Company as a whole or, except with respect to stockholder return metrics, to a region, business unit, affiliate or business segment, and may be measured either on an absolute basis, a per share basis or relative to a pre-established target, to a previous period’s results or to a designated comparison group, and, with respect to financial metrics, which may be determined in accordance with United States Generally Accepted Accounting Principles (“ GAAP ”), in accordance with accounting principles established by the International Accounting Standards Board (“ IASB Principles ”) or which may be adjusted when established to either exclude any items otherwise includable under GAAP or under IASB Principles or include any items otherwise excludable under GAAP or under IASB Principles. In all other respects, Performance Goals will be calculated in accordance with the Company’s financial statements, generally accepted accounting principles, or under a methodology

-16-

established by the Administrator prior to or at the time of the issuance of an Award and which is consistently applied with respect to a Performance Goal in the relevant Performance Period. In addition, the Administrator will adjust any performance criteria, Performance Goal or other feature of an Award that relates to or is wholly or partially based on the number of, or the value of, any stock of the Company, to reflect any stock dividend or split, repurchase, recapitalization, combination, or exchange of shares or other similar changes in such stock. The Performance Goals may differ from Participant to Participant and from Award to Award. Prior to the Determination Date, the Administrator will determine whether any significant element(s) will be included in or excluded from the calculation of any Performance Goal with respect to any Participant.

(c)     Procedures . To the extent necessary to comply with the performance-based compensation provisions of Code Section 162(m), with respect to any Award granted subject to Performance Goals, within the first twenty five percent (25%) of the Performance Period, but in no event more than ninety (90) days following the commencement of any Performance Period (or such other time as may be required or permitted by Code Section 162(m)), the Administrator will, in writing, (i) designate one or more Participants to whom an Award will be made, (ii) select the Performance Goals applicable to the Performance Period, (iii) establish the Performance Goals, and amounts of such Awards, as applicable, which may be earned for such Performance Period, and (iv) specify the relationship between Performance Goals and the amounts of such Awards, as applicable, to be earned by each Participant for such Performance Period. Following the completion of each Performance Period, the Administrator will certify in writing whether the applicable Performance Goals have been achieved for such Performance Period. In determining the amounts earned by a Participant, the Administrator will have the right to reduce or eliminate (but not to increase) the amount payable at a given level of performance to take into account additional factors that the Administrator may deem relevant to the assessment of individual or corporate performance for the Performance Period. A Participant will be eligible to receive payment pursuant to an Award for a Performance Period only if the Performance Goals for such period are achieved.

(d)     Additional Limitations . Notwithstanding any other provision of the Plan, any Award which is granted to a Participant and is intended to constitute qualified performance based compensation under Code Section 162(m) will be subject to any additional limitations set forth in the Code (including any amendment to Code Section 162(m)) or any regulations and ruling issued thereunder that are requirements for qualification as qualified performance-based compensation as described in Code Section 162(m), and the Plan will be deemed amended to the extent necessary to conform to such requirements.

12.     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 GAAP) of more than $1,000,000, increased to $2,000,000 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 GAAP) of more than $1,000,000, increased to $2,000,000 in connection with his or her initial service.

-17-

13.     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.     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.

15.     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 Sections 3, 6, 7, 8, 9, and 10 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

-18-

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 15(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 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 15(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,

-19-

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.     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.

17.     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.

18.     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.

-20-

19.     Term of Plan . Subject to Section 23 of the Plan, the Plan will become effective upon stockholder approval at the 2016 Annual Meeting of Stockholders. It will continue in effect for a term of ten (10) years from the date adopted by the Board, unless terminated earlier under Section 20 of the Plan.

20.     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.

21.     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.

22.     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.

23.     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.

TWITTER, INC.

2016 EQUITY INCENTIVE PLAN

RESTRICTED STOCK UNIT AGREEMENT

Unless otherwise defined herein, the terms defined in the Twitter, Inc. 2016 Equity Incentive Plan (the “Plan”) will have the same defined meanings in this Restricted Stock Unit Agreement, which includes the Notice of Restricted Stock Unit Grant (the “Notice of Grant”), Terms and Conditions of Restricted Stock Unit Grant, attached hereto as Exhibit A , and all appendices and exhibits attached thereto (the “Award Agreement”).

NOTICE OF RESTRICTED STOCK UNIT GRANT

Participant:

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:

Vesting Schedule :

Subject to any acceleration provisions contained in the Plan or set forth in the Award Agreement, the Restricted Stock Units will vest in accordance with the vesting schedule as described on the Charles Schwab Corporation platform for this Award.

By Participant’s signature below, Participant agrees 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 , all of which are made a part of this document. Participant has reviewed the Plan and this Award Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Award Agreement and fully understands all provisions of the Plan and this Award 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 Award Agreement. Participant further agrees to notify Twitter, Inc. upon any change in the residence address indicated above.

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 defined below and as applicable), which are incorporated herein by reference.

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 schedule described on the Charles Schwab Corporation platform for this Award. Restricted Stock Units scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest 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. Unless otherwise provided by the Administrator, 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.

Notwithstanding anything in the Award Agreement to the contrary, 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 Award 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 Award Agreement, the Participant would remain entitled to the acceleration of vesting under the Separate Agreement).

-2-

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. If Participant is a U.S. taxpayer, 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 prior sentence may be superseded in a future agreement or amendment to this Award Agreement only by direct and specific reference to such sentence.

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 Participant’s 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 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). However, in no event will the Company reimburse Participant, or be otherwise responsible for, any taxes or costs that may be imposed on Participant as a result of Section 409A. 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 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 the second paragraph of Section 3 of this Award Agreement and any 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 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. Until determined otherwise by the Company, the method specified in clause (c) 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 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.

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.

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.

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.

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.

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 Restricted Stock Units 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 7 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 vesting of the Restricted Stock Units.

TWITTER, INC.

2016 EQUITY INCENTIVE PLAN

PERFORMANCE-BASED RESTRICTED STOCK UNIT AGREEMENT

Unless otherwise defined herein, the terms defined in the Twitter, Inc. 2016 Equity Incentive Plan (the “Plan”) will have the same defined meanings in this Performance-Based Restricted Stock Unit Agreement, which includes the Notice of Performance-Based Restricted Stock Unit Grant (the “Notice of Grant”), Terms and Conditions of Performance-Based Restricted Stock Unit Grant, attached hereto as Exhibit A and the Performance-Based Restricted Stock Unit Matrix (the “Performance Matrix”), attached hereto as Exhibit B , and all appendices, schedules, and exhibits attached thereto (the “Award Agreement”).

NOTICE OF PERFORMANCE-BASED RESTRICTED STOCK UNIT GRANT

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

Vesting Schedule:

Subject to any acceleration provisions contained in the Plan or set forth below (including the Exhibits hereto), any Earned Units will vest in accordance with the vesting schedule as described on the Charles Schwab Corporation platform for this Award.

By Participant’s signature below, Participant agrees that this Award of Performance-Based 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 Performance-Based Restricted Stock Unit Grant, attached hereto as Exhibit A , and the Performance Matrix, attached hereto as Exhibit B , all of which are made a part of this document, all of which are made a part of this document. Participant has reviewed the Plan and this Award Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Award Agreement and fully understands all provisions of the Plan and this Award 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 Award Agreement. Participant further agrees to notify the Company upon any change in the residence address indicated below.

EXHIBIT A

TERMS AND CONDITIONS OF PERFORMANCE-BASED 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 Performance-Based 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.

2.     Company’s Obligation to Pay . Each Performance-Based Restricted Stock Unit represents the right to receive a Share on the date it vests. Unless and until the Performance-Based 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 Performance-Based Restricted Stock Units. Prior to actual payment of any vested Performance-Based Restricted Stock Units, such Performance-Based Restricted Stock Units will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company. Any Performance-Based 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 Performance-Based 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 Performance-Based Restricted Stock Units payable under this Award Agreement.

3.     Vesting Schedule . Except as provided in Section 4, and subject to Section 5, the Performance-Based Restricted Stock Units awarded by this Award Agreement will vest in in accordance with the vesting schedule described on the Charles Schwab Corporation platform for this Award. Performance-Based 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. Unless otherwise provided by the Administrator, in the event Participant ceases to be a Service Provider for any or no reason before Participant vests in the Performance-Based Restricted Stock Units, the Performance-Based Restricted Stock Units and Participant’s right to acquire any Shares hereunder will immediately terminate, subject to Applicable Laws.

Notwithstanding the foregoing, the vesting of the Performance-Based Restricted Stock Units shall be subject to any vesting acceleration provisions applicable to these Performance-Based Restricted Stock Units contained in the Plan, the Award Agreement 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 Award 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 Performance-Based 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 Award Agreement, the Participant would remain entitled to the acceleration of vesting under the Separate Agreement).

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 Performance-Based Restricted Stock Units at any time, subject to the terms of the Plan. If so accelerated, such Performance-Based Restricted Stock Units will be considered as having vested as of the date specified by the Administrator. If Participant is a U.S. taxpayer, 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 prior sentence may be superseded in a future agreement or amendment to this Award Agreement only by direct and specific reference to such sentence.

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 Performance-Based 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 Participant’s 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 Performance-Based Restricted Stock Units 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 Performance-Based 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 Performance-Based 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 Performance-Based 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). However, in no event will the Company reimburse Participant, or be otherwise responsible for, any taxes or costs that may be imposed on Participant as a result of Section 409A. 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 as a Service Provider . Notwithstanding any contrary provision of this Award Agreement, the balance of the Performance-Based 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 the second paragraph of Section 3 of this Award Agreement and 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

-2-

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 Performance-Based 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 Performance-Based 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 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. Until determined otherwise by the Company, the method specified in clause (c) 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 Performance-Based Restricted Stock Units otherwise are scheduled to vest pursuant to Sections 3 or 4 or Tax-Related Items related to Performance-Based Restricted Stock Units otherwise are due, Participant will permanently forfeit such Performance-Based Restricted Stock Units and any right to receive Shares thereunder and the Performance-Based 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 Performance-Based 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 Performance-Based 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 PERFORMANCE-BASED RESTRICTED STOCK UNITS PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE

-3-

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 PERFORMANCE-BASED 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 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 Performance-Based Restricted Stock Units is voluntary and occasional and does not create any contractual or other right to receive future grants of Performance-Based Restricted Stock Units, or benefits in lieu of Performance-Based Restricted Stock Units, even if Performance-Based Restricted Stock Units have been granted in the past;

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

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

(h)    for purposes of the Performance-Based 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 Performance-Based 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

-4-

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 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 Performance-Based 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 Performance-Based Restricted Stock Units and the benefits evidenced by this Award Agreement do not create any entitlement to have the Performance-Based 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:

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.

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 Performance-Based 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.

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.

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.

17.     Award Agreement Governs . This Award Agreement is subject to all terms and provisions of the Plan. Subject to Section 20(c) of the Plan, in the event of a conflict between one or more provisions of this Award Agreement and one or more provisions of the Plan, the provisions of the Award Agreement will govern. Capitalized terms used and not defined in this Award Agreement will have the meaning set forth in the Plan.

19.     Electronic Delivery and Acceptance . The Company may, in its sole discretion, decide to deliver any documents related to Performance-Based Restricted Stock Units awarded under the Plan or future Performance-Based Restricted Stock Units that may be awarded under the Plan by electronic means or request Participant’s consent to participate in the Plan by electronic means. Such means of electronic delivery may include but do not necessarily include the delivery of a link to a Company intranet or the Internet site of a third party involved in administering the Plan, the delivery of the document via e-mail or such other means of

electronic 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.

24.     Governing Law and Venue . This Award Agreement will be governed by the laws of Delaware without giving effect to the conflict of law principles thereof. For purposes of litigating any dispute that arises under this Award of Performance-Based Restricted Stock Units or this Award Agreement, the parties hereby submit to and consent to the jurisdiction of the State of California, and agree that such litigation will be conducted in the courts of the County of San Francisco, California, or the federal courts for the United States for the Northern District of California, and no other courts, where this Award of Performance-Based Restricted Stock Units is made and/or to be performed.

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 20(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 ISO, 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 schedule described on the Charles Schwab Corporation platform for this Option. 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.

3

(b)     Method of Exercise . This Option is exercisable by delivery of an exercise notice (the “Exercise Notice”), in the form attached as Exhibit B 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 and that are owned free and clear of any liens, claims, encumbrances, or security interests, 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,

4

if Participant is subject to tax in more than one jurisdiction between the Date of Grant and the date of 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 (which may be in book entry form) will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to Participant (including through electronic delivery to a brokerage account). 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, WHICH

5

UNLESS PROVIDED OTHERWISE UNDER APPLICABLE LAW IS AT THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND 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;

6

(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:

7

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 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

8

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 Participant’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.

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.

16.     Plan Governs . This Agreement is subject to all terms and provisions of the Plan. In the event of a conflict between one or more provisions of this Agreement and one or more provisions of the Plan, the provisions of the Plan will govern. Capitalized terms used and not defined in this Agreement will have the meaning set forth in the Plan.

22

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.

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.

RULES OF THE MAGIC PONY TECHNOLOGY LIMITED

EMI SHARE OPTION SCHEME

(APPROVED BY THE BOARD OF DIRECTORS ON AUGUST 27, 2015)

Index

In the Rules, unless the context requires otherwise, the following words and expressions are defined or otherwise explained by the provisions indicated:

3

4

5

6

Words or expressions used herein shall where appropriate:

EMI Options granted at any time pursuant to the Rules are granted for commercial reasons in order to recruit or retain an Eligible Employee and not as part of a scheme or arrangement the main purpose, or one of the main purposes, of which is the avoidance of tax.

over such number of Shares at such Option Price and with such conditions of exercise as the Company may determine.

The Option shall be agreed in writing between the Company and the Option Holder, and shall state:

7

8

The Company shall at all times keep available Shares to satisfy the exercise to the full extent still possible of all Options which have neither lapsed nor been fully exercised taking account of any other obligations of the Company to provide shares of the same class as Shares.

Save as provided in Rule 9.4, no Option nor any right thereunder shall be capable of being transferred, assigned or charged in any manner whatsoever. Upon any such purported transfer, assignment, or charge the Option shall immediately lapse and cease to be exercisable.

Subject to rules 9.2, 9.3, 9.4 and 12 below an Option:

9

If the Option Holder is a Good Leaver:

If an Option Holder dies, the Option shall be exercisable in full regardless of whether it has Vested by the Personal Representatives, provided that the Option shall only be exercisable within 12 months of the Option Holder’s death.

An Option shall be exercisable, in whole or in part, by the delivery to the secretary of the Company of the following:

10

The Company shall issue or procure the transfer of Shares to be allotted or transferred pursuant to the exercise of an Option to the Option Holder such number of Shares within 30 days following the effective date of exercise of the Option.

11

then the Company shall be authorised by the Option Holder to reduce the number of Shares otherwise deliverable to the Option Holder upon the exercise of an Option as may be sufficient to produce a sum which (after allowance for the costs and expenses of such a sale) may discharge (and shall be applied in discharge of) the Option Holder’s liability to the Relevant Company under Rule 10.4(a) or any agreement or election pursuant to Rule 10.4(c) and the Company may exercise all such powers and may appoint any of its officers to sign all such documents in the name of the Option Holder and as his act and deed as may be necessary for this purpose.

An Option shall immediately cease to be exercisable and shall lapse on the earliest of:

12

If any person obtains Control of the Company as a result of:

(“an Offer”), an Option may be exercised to the extent Vested in accordance with the provisions of Rule 12.2.

For the purposes of Rule 12.1 a person shall be deemed to have obtained Control of the Company if he and others acting in concert with him have together obtained Control of it.

13

If any person obtains Control of the Company in pursuance of a compromise or arrangement sanctioned by the court under section 899 of the Companies Act (“a Compromise”), an Option may be exercised to the extent Vested within 90 days (or within any longer time period as referred to in section 532(1)(b) ITEPA) of the court sanctioning the Compromise. An Option shall not be exercisable after the said 90 days (or longer time period as referred to in section 532(1)(b) ITEPA) but may still be released under Rule 13 within the period of six months following the court sanction of the Compromise and, on the expiry of the said six month period, the Option shall lapse.

If any person becomes bound or entitled to acquire shares under Chapter 3, Part 28 of the Companies Act, an Option may be exercised to the extent Vested at any time when that person remains so bound or entitled.

If a general meeting of the Company is called at which it is proposed to pass a resolution for the members’ voluntary winding up of the Company, the Company shall notify the Option Holder as soon as practicable of this fact. The Option may be exercised to the extent Vested during the period of such notice (such exercise being conditional on such resolution being passed and taking effect immediately thereafter) and such portion of the Option not otherwise exercised before such resolution has been passed shall thereupon lapse. Where the Option Holder has exercised the Option pursuant to this Rule 12.6 and the resolution referred to above has been passed then (subject to the consent of the Company’s liquidator where such is required by section 88 of the Insolvency Act 1986) the exercise of the Option shall take effect immediately and the Option Holder shall be entitled to share in the assets of the Company with the existing shareholders in the same manner as the Option Holder would have been entitled had the Option Holder been the registered owner of the relevant Shares before the resolution was passed. For the avoidance of doubt, this Rule 12.6 will not apply to a creditors’ voluntary winding up.

An Option may not be exercised under rule 12.1 if the Offer is part of a reorganisation so that the shareholders of the Acquiring Company hold their shares in the Acquiring Company in the same proportions as they held their shares in the Company.

An Option may be exercised to the extent Vested within 90 days (or within any longer time period as referred to in section 532(1)(b) ITEPA) of a Sale of the Business and the Company shall notify the Option Holder as soon as practicable of this fact.

If the Company’s shares are admitted to listing on the Main Market of the London Stock Exchange, AIM or to any recognised investment exchange (as defined in section 285 of the Financial Services and Markets Act 2000), the Option shall continue to vest in accordance with the Vesting Schedule and the Option may be exercised to the extent Vested during such periods as the Directors shall determine in their discretion.

14

If any company (“the Acquiring Company”):

an Option Holder may at any time within the period set out in Rule 13.2, by agreement with the Acquiring Company, release any Option which has not lapsed (“the Old Option”) in consideration of the grant to him of an Option (“the New Option”) which is equivalent to the Old Option but relates to shares in the Acquiring Company and qualifies as a Replacement Option as set out in rules 13.4 and 13.5.

The New Option must be granted within the following periods:

15

Subject to Rule 13.5, a New Option qualifies as a Replacement Option only if:

16

The number of Shares over which an Option is granted and the Option Price thereof shall be adjusted in such manner as the Directors shall determine following any capitalisation issue, rights issue, subdivision, consolidation or reduction of share capital of the Company or any other variation of share capital to the intent that (as nearly as may be) the total Option Price multiplied by the number of Shares that is payable in respect of an Option shall remain unchanged.

Subject to Rule 15.3 below, an adjustment may be made under Rule 15.1 above which would have the effect of reducing the Option Price of unissued shares to less than the nominal value of a Share, but only if, and to the extent that, the Directors shall be authorised to capitalise from the reserves of the Company a sum equal to the amount by which the aggregate nominal value of the Shares in respect of which the Option is exercisable exceeds the aggregate adjusted Option Price, so that on exercise of any Option in respect of which the Option Price has been reduced, the Directors shall capitalise and apply such sum (if any) as is necessary to pay up the amount by which the aggregate nominal value of the Shares in respect of which the Option is exercised exceeds the aggregate Option Price for such Shares.

Where an Option subsists over both issued and unissued Shares, an adjustment permitted by Rule 15.2 above, may only be made if the reduction of the Option Price of both issued and unissued Shares can be made to the same extent.

17

The Directors shall notify Option Holders of any adjustment made under this Rule 15 as soon as reasonably practicable and may take such steps and the Company shall execute such documents as it considers necessary to give effect to such adjustment. Furthermore, and without limitation to the generality of the foregoing, the Directors may call in, cancel, endorse, issue or reissue any Option Agreement subsequent upon such adjustment.

and for the purpose of this Rule 16.1(d) the Option Holders or any class of Option Holders shall be treated as the holders of a separate class of share capital and the provisions of the Articles of Association of the Company relating to class meetings shall apply mutatis mutandis.

18

The Scheme shall terminate upon the tenth anniversary of the Adoption Date or at any earlier time by the passing of a resolution by the Directors. Termination shall be without prejudice to the subsisting rights of Option Holders.

If there is any conflict between the provisions of the Rules as they apply to EMI Options and Schedule 5, Schedule 5 shall take precedence in respect of EMI Options.

The decision of the Directors in any dispute or question relating to any Option shall be final and conclusive subject to the terms of this Scheme.

The Rules shall be governed by and construed in accordance with English law.

Except as expressly provided by the Company, a person who is not the Option Holder or a company who is not a member of the Group has no right under the Contracts (Rights of Third Parties) Act 1999 to rely upon or enforce any provisions of this Scheme, but this does not affect any right or remedy of a third party which exists or is available apart from that Act. The Option Holder may not declare himself a trustee of his rights under this Scheme for the benefit of any third parties.

The Company and the Employer Company (if different) from time to time will collect, hold and process the Option Holder’s personal information for the purposes of the administration of this Option. The Company will not use such personal information for any purpose other than the administration of the Option, unless the Option Holder’s consent to that use is obtained.

19

Notwithstanding any other provision of the Scheme the Directors may amend or add to the provisions of the Scheme and the terms of Option Agreements they consider necessary or desirable to take account of, or to mitigate, or to comply with relevant overseas taxation, securities or exchange control laws, provided that the terms of Options granted to such Employees are not more favourable overall than the terms of Awards granted to other Employees.

The Group shall not be liable to the Option Holder for any tax or additional tax or national insurance payable by the Option Holder upon the exercise of an Option or upon the subsequent disposal of any Shares acquired upon exercise of the Option being tax or national insurance payable because of a failure to qualify for relief under sections 529 to 532 of ITEPA in consequence of anything done by the Group.
