Section 3.1    Commencement of Exercisability.

(a)    Subject to Sections 3.2, 3.3, 5.9 and 5.14, the Option will vest and become exercisable according to the vesting schedule in the Grant Notice, except that any fraction of an Option that would otherwise vest and become exercisable will be accumulated and will vest and become exercisable only when a whole Share has accumulated.

(b)    Unless (a) specified in the Grant Notice or in any severance plan or policy sponsored or maintained by the Company to which Participant is subject, (b) as otherwise determined by the Administrator or (c) as provided in a binding written agreement between Participant and the Company, any portion of the Option that has not become vested and exercisable on or prior to the Termination of Service shall be forfeited upon the Termination of Service and shall not thereafter become vested or exercisable.

Section 3.2    Duration of Exercisability. The installments provided for in the vesting schedule set forth in the Grant Notice are cumulative. Each such installment that becomes vested and exercisable pursuant to the vesting schedule set forth in the Grant Notice shall remain vested and exercisable until it becomes unexercisable under Section 3.3 hereof.

The Company may deduct an amount sufficient to satisfy such tax obligations based on the applicable statutory withholding rates (or such other rate as may be determined by the Company after considering any accounting consequences or costs) from any payment of any kind otherwise due to a Participant.

(b)    Participant is ultimately liable and responsible for all taxes owed in connection with the Option, regardless of any action the Company takes with respect to any tax withholding obligations that arise in connection with the Option. The Company makes no representation or undertaking regarding the treatment of any tax withholding in connection with the awarding, vesting or exercise of the Option or the subsequent sale of Shares. The Company does not commit and is under no obligation to structure the Option to reduce or eliminate Participant’s tax liability.

Section 5.13    Entire Agreement. The Plan, the Grant Notice and this Agreement (including any exhibit hereto) constitute the entire agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof.

Section 5.14    Section 409A. This Option is not intended to constitute “nonqualified deferred compensation” within the meaning of Section 409A and shall be interpreted consistent with such intent. However, notwithstanding any other provision of the Plan, the Grant Notice or this Agreement, if at any time the Administrator determines that this Option (or any portion thereof) may be subject to Section 409A, the Administrator shall have the right in its sole discretion (without any obligation to do so or to indemnify Participant or any other Person for failure to do so) to adopt such amendments to the Plan, the Grant Notice or this Agreement, or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, as the Administrator determines are necessary or appropriate for this Option either to be exempt from the application of Section 409A or to comply with the requirements of Section 409A.

Section 5.15    Agreement Severable. In the event that any provision of the Grant Notice or this Agreement is held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not be construed to have any effect on, the remaining provisions of the Grant Notice or this Agreement.

Section 5.16    Limitation on Participant’s Rights. Participation in the Plan confers no rights or interests other than as herein provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and shall not be construed as creating a trust.

Participant shall have only the right to receive Shares as a general unsecured creditor with respect to the Option, as and when exercised pursuant to the terms hereof.

Section 5.17    Counterparts. The Grant Notice may be executed in one or more counterparts, including by way of any electronic signature, subject to Applicable Law, each of which shall be deemed an original and all of which together shall constitute one instrument.

Section 5.18    Broker-Assisted Sales. In the event of any broker-assisted sale of Shares in connection with the payment of withholding taxes as provided in Section 9.5 of the Plan or the payment of the Exercise Price as provided in Section 4.4(b): (a) any Shares to be sold through a broker-assisted sale will be sold on the day the tax withholding obligation or exercise of the Option, as applicable, occurs or arises, or as soon thereafter as practicable; (b) such Shares may be sold as part of a block trade with other participants in the Plan in which all participants receive an average price; (c) Participant will be responsible for all broker’s fees and other costs of sale, and Participant agrees to indemnify and hold the Company harmless from any losses, costs, damages, or expenses relating to any such sale; (d) to the extent the proceeds of such sale exceed the applicable tax withholding obligation or Exercise Price, the Company agrees to pay such excess in cash to Participant as soon as reasonably practicable; (e) Participant acknowledges that the Company or its designee is under no obligation to arrange for such sale at any particular price, and that the proceeds of any such sale may not be sufficient to satisfy the applicable tax withholding obligation or Exercise Price; and (f) in the event the proceeds of such sale are insufficient to satisfy the applicable tax withholding obligation, Participant agrees to pay immediately upon demand to the Company with respect to which the withholding obligation arises an amount in cash sufficient to satisfy any remaining portion of the Company’s withholding obligation.

Section 5.19    Clawback. The Option shall at all times be subject to any clawback or similar policies or programs established by the Company, as may be amended from time to time (each, a “Clawback Policy”). In addition (and without limiting the Company’s rights and the Participant’s obligations under any Clawback Policy), to the extent required by applicable law or the rules and regulations of the Nasdaq Global Market or any other securities exchange or interdealer quotation on which the Common Stock is listed or quote, the Option shall be subject (including on a retroactive basis) to clawback, forfeiture or similar requirements (and such requirements shall be deemed incorporated by reference into this Agreement) and, upon request by the Company, Participant shall execute an acknowledgment with respect to any applicable Clawback Policy.

Section 5.20    Incentive Stock Options. Participant acknowledges that to the extent the aggregate Fair Market Value of Shares (determined as of the time the option with respect to the Shares is granted) with respect to which Incentive Stock Options, including this Option (if applicable), are exercisable for the first time by Participant during any calendar year exceeds $100,000 or if for any other reason such Incentive Stock Options do not qualify or cease to qualify for treatment as “incentive stock options” under Section 422 of the Code, such Incentive Stock Options shall be treated as Non-Qualified Stock Options. Participant further acknowledges that the rule set forth in the preceding sentence shall be applied by taking the Option and other stock options into account in the order in which they were granted, as determined under Section 422(d) of the Code and the Treasury Regulations thereunder. Participant also acknowledges that an Incentive Stock Option exercised more than three (3) months after Participant’s Termination of Service, other than by reason of death or disability, will be taxed as a Non-Qualified Stock Option.

Section 5.21    Notification of Disposition. If this Option is designated as an Incentive Stock Option, Participant shall give prompt written notice to the Company of any disposition or other transfer of any Shares acquired under this Agreement if such disposition or transfer is made (a) within two (2) years from the Grant Date or (b) within one (1) year after the transfer of such Shares to Participant. Such notice shall specify the date of such disposition or other transfer and the amount realized, in cash, other property, assumption of indebtedness or other consideration, by Participant in such disposition or other transfer.

Section 5.22     Special Provisions for Options Granted to Participants Outside the U.S. If the Participant performs services for the Company outside of the United States, the Options shall be subject to the special provisions, if any, for the Participant’s country of residence, as set forth in the Foreign Annex. If the Participant relocates to the country included in the Foreign Annex during the life of the Options, the special provisions for such country shall apply to the Participant, to the extent the Company determines that the application of such provisions is necessary or advisable in order to comply with local law or facilitate the administration of the Plan. The Company reserves the right to impose other

requirements on the Options and the Shares, to the extent the Company determines it is necessary or advisable in order to comply with local laws or facilitate the administration of the Plan, and to require the Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.
