The Units are subject to the terms and conditions set forth in this Restricted Stock Unit Grant Notice (the “Grant Notice”), the Restricted Stock Unit Agreement attached hereto as Exhibit A (the “Agreement”), and the Plan, each of which is incorporated herein by reference. Capitalized terms used in this Grant Notice or in the Agreement which are not explicitly defined herein will have the meaning ascribed to them in the Plan.

By accepting this Award electronically pursuant to the Company’s online grant acceptance policy, Participant agrees to be bound by the terms and conditions of the Plan, the Agreement and the Grant Notice. Participant has reviewed the Agreement, the Plan and the Grant Notice in their entirety, has had an opportunity to obtain the advice of counsel prior to executing the Grant Notice and fully understands all provisions of the Grant Notice, the Agreement, and the Plan. Participant hereby agrees to accept as binding, conclusive and final all decisions and interpretations of the Administrator upon any questions arising under the Plan, the Grant Notice or the Agreement.

[In particular, Participant has reviewed Section 9 of the Agreement, and represents and warrants that as of the date hereof, he or she: (i) is not aware of any material, nonpublic information with respect to the Company or any securities of the Company, (ii) is not subject to any legal, regulatory or contractual restriction that would prevent the Company from conducting a “sell to cover” transaction as described in Section 9 of the Agreement, (iii) does not have, and will not attempt to exercise, authority, influence or control over any sales of Shares effected by the Company or its agents pursuant to the Agreement, and (iv) is entering into the Agreement and the resulting “sell to cover” instruction in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b5-1 (regarding trading of the Company’s securities on the basis of material nonpublic information) under the Exchange Act.

that this “sell to cover” instruction will comply with the requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act and be interpreted to comply with the requirements of Rule 10b5-1(c) under the Exchange Act.]

This Restricted Stock Unit Award Agreement (this “Agreement”) governs the award of Restricted Stock Units to the Participant identified on the accompanying Grant Notice.

1.Grant of Units. Effective as of the Date of Grant, the Company grants the Participant the number of Units listed on the Grant Notice. The Units are subject to the vesting, payment, and other provisions of this Agreement and the Plan. Each Unit is subject to settlement into one share of Common Stock of the Company (a “Share”) that will be delivered to the Participant when and if such Unit becomes vested subject to the terms of this Agreement.

2.Vesting; Forfeiture. The Units are unvested when granted and will vest in accordance with the vesting schedule set forth on the Grant Notice, subject to Participant’s Continuous Service through the vesting date(s). Vesting will terminate upon the termination of Participant’s Continuous Service. All Units that are not vested upon the termination of Participant’s Continuous Service for any reason will be immediately forfeited.

3.Delivery of Shares to Settle Vested Units. Units that become vested as provided in Section 2 will be settled by delivering to Participant a number of Shares equal to the number of vested Units as soon as practicable after the date on which the Units vest, provided that the Company may provide a reasonable delay in the issuance or delivery of the Shares to address tax withholding and other administrative matters and provided further that delivery of the Shares will occur no later than two and one-half months following the conclusion of the year in which the vesting occurs. At the time of settlement, the Company will, at its election, either: (a) issue a certificate representing the Shares deliverable pursuant to this Agreement; or (b) not issue any certificate representing the Shares deliverable pursuant to this Agreement and instead document the Participant’s interest in the Shares by registering such Shares with the Company’s transfer agent (or another custodian selected by the Company) in book-entry form in the Participant’s name.

4.Capitalization Changes. The number of Units convertible to Shares subject to this Award may be adjusted from time to time by the Administrator to account for changes in capitalization as described in Section 11 of the Plan.

5.Rights as a Stockholder. The Units represent a right to payment from the Company if the conditions of the Agreement are met and do not give the Participant ownership of any Common Stock prior to delivery as provided in Section 3. Participant will not have any rights and/or privileges of a stockholder of the Company with respect to the Units prior to such delivery. If Participant becomes vested in Units as provided in Section 2, any Shares to which Participant becomes entitled will be delivered to Participant as provided in Section 3, and Participant will have full ownership of the Shares upon such delivery.

6.Non-Transferability of the Award. The Units and the right to payment under this Agreement are not transferable, may not be sold, exchanged, transferred, pledged, hypothecated, encumbered or otherwise disposed of except as provided in the Plan. Any purported transfer of the Units or the right to payment under this Agreement is null and void and will not be given effect.

7.Award Not A Service Contract. Neither the Award nor this Agreement is an employment or service contract, and nothing this Agreement confers or will be construed as conferring upon the Participant any right to continue in the employment or service of the Company or a Related Entity, or as interfering with or restricting in any way the right of either party to terminate such employment or service at any time.

8.Tax Consequences. Participant acknowledges that he/she understands the federal, state, and local tax consequences of the Award and the issuance, vesting, forfeiture, and delivery provisions hereof relating to the Units. Participant will rely solely on the advice of his/her own tax advisors and not on any statements or representations of the Company or any of its agents. Participant understands that Participant (and not the Company) will be responsible for his/her own tax liability that may arise as a result of the Award or the transactions contemplated by this Agreement. The Company has no duty or obligation to minimize the tax consequences associated with this Award to the Participant and will not be liable to the Participant for any adverse tax consequences arising in connection with this Award.

9.Withholding Obligations. Participant understands that, at the time that Participant becomes vested and/or receives payment for any Units (including through the delivery of Shares), the Company may be required to withhold federal, state and local income and employment taxes. Participant hereby authorizes the Company to satisfy any required withholding to satisfy federal, state, local, payroll, and foreign tax withholding obligations of the Company or any Related Entity that arise in connection with the Units through any method authorized in the Plan. Unless otherwise determined by the Administrator in its sole discretion, Participant acknowledges that the Company will satisfy such tax withholding obligation by arranging for the sale, by a broker of the Company’s choosing, of such number of Shares otherwise deliverable to the Participant equal in value to the tax obligation required to be withheld (plus any applicable broker commission). Participant understands that all matters with respect to the total amount of taxes to be withheld in respect of such compensation income will be determined by the Company in its reasonable discretion. Participant further understands that, although the Company will pay withheld amounts to the applicable taxing authorities, Participant remains responsible for payment of all taxes due as a result of income arising under the Agreement.

extent necessary to avoid the imposition of any additional taxes or penalties under Section 409A, the commencement of any payments under this Agreement will be deferred until the date that is six months and one day following the Participant’s termination of Continuous Service (or, if earlier, the date of death of the Participant) and will instead be paid on the date that immediately follows the end of such period (or death) or as soon as administratively practicable within 30 days thereafter.

11.Notices. Any notice or request required or permitted hereunder must be given in writing to each of the other parties hereto and will be deemed effectively given on the earlier of (a) the date of personal delivery, (b) one business day after deposit in the custody of a reputable overnight delivery service with next business day charges prepaid, (c) when sent by email or other electronic delivery service, or (d) three business days after the date of deposit in the United States Mail by registered or certified mail, postage prepaid, return receipt requested, addressed in the case of the Company to the Company’s Chief Executive Officer at the Company’s primary business address and in the case of the Participant to the most recent address shown in the Company’s records.

12.Incorporation of the Plan; Entire Agreement; Modification. The Award is subject to all the provisions of the Plan, the provisions of which are hereby made a part of this Agreement, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan.
