Form of Notice of Stock Unit Grant and Stock Unit Agreement (Annual Director Grant) under the 2014 Amended and Restated Equity Incentive Plan

The Company hereby grants you an award of restricted Stock Units (“RSUs”), as set forth in the Notice of Stock Unit Grant (the “Notice of Grant”) and subject to the terms and conditions in this Stock Unit Agreement (this “Agreement”) and the Company’s Amended and Restated 2014 Equity Incentive Plan (as amended, the “Plan”). Unless otherwise defined herein, the terms defined in the Plan shall have the same defined meanings in this Agreement.

Each RSU represents the right to receive a share of Common Stock of the Company (a “Share”) on the vesting date. Unless and until the RSUs vest, you will have no right to receive Shares underlying the RSUs. Prior to actual distribution of Shares pursuant to any vested RSUs, such RSUs will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company. Settlement of any vested RSUs shall be made in whole Shares only.

Subject to the next paragraph (Forfeiture upon Termination of Service), and except as otherwise set forth in any duly authorized written agreement between you and the Company, the RSUs awarded by this Agreement will be scheduled to vest in accordance with the schedule set forth in the Notice of Grant. If after the Date of Grant the amount of time you are scheduled to provide Service is reduced (e.g., you move from providing Service on a full-time basis to a part-time basis), then the vesting schedule specified in the Notice of Grant may be adjusted in accordance with the Company’s part-time work policy or the terms of an agreement between you and the Company pertaining to your reduced Service schedule.

Notwithstanding any contrary provision of this Agreement, if you terminate Service for any or no reason prior to vesting, the unvested RSUs awarded by this Agreement will thereupon be forfeited at no cost to the Company, except as otherwise set forth in the Notice of Grant or in any duly authorized written agreement between you and the Company.

For purposes of this RSU, your Service does not terminate when you go on a military leave, a sick leave or another bona fide leave of absence, if the leave was approved by the Company in writing and if continued crediting of Service is required by the terms of the leave or by applicable law. Your Service will terminate, however, if you do not immediately return to active work after the leave of absence ends. If you go on a leave of absence, then the vesting schedule specified in the Notice of Grant may be adjusted in accordance with the Company’s leave of absence policy or the terms of your leave of absence.

Any RSUs that vest hereunder will be paid to you (or in the event of your death, to your estate) in Shares. Subject to any payment delay required under the following two paragraphs, the vested RSUs shall be paid in whole Shares as soon as practicable after vesting, but in each such case within sixty (60) days following the vesting date. In no event will you be permitted, directly or indirectly, to specify the taxable year of payment of any RSUs payable under this Agreement.

Notwithstanding anything in the Plan or this Agreement or any other agreement (whether entered into before, on or after Date of Grant), if the vesting of the balance, or some lesser portion of the balance, of the RSUs is accelerated in connection with your termination of Service (provided that such termination is a “separation from service” within the meaning of Section 409A, as determined by the Company), other than due to your death, and if (x) you are a “specified employee” within the meaning of Section 409A at the time of such termination of Service and (y) the payment of such accelerated RSUs will result in the imposition of additional tax under Section 409A if paid to you on or within the six (6) month period following your termination of Service, then the payment of such accelerated RSUs will not be made until the date six (6) months and one (1) day following the date of your termination of Service, unless you die following your termination of Service, in which case, the RSUs will be paid in whole Shares to your estate as soon as practicable following your death.

If the Administrator determines to allow you to elect to defer the issuance of any Shares that are otherwise deliverable with respect to any vested RSUs, you may do so upon such terms and conditions as may be determined by the Administrator in its sole discretion, subject to the Administrator’s determination that such right of deferral or any term thereof complies with Applicable Laws or regulations in effect from time to time, including, but not limited to, Section 409A. In the event of the Administrator’s determination otherwise, the Administrator may, in its discretion, deny Participant such right of deferral altogether, modify the terms of the deferral and/or add such requirements as it deems necessary or advisable to comply with Applicable Law or regulations. If the Administrator permits Participant to elect to defer the proceeds of any vested RSUs in accordance with this paragraph, payment of the deferred vested RSUs will be made in accordance with the terms of your deferral election.

It is the intent of this 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 RSUs provided under this Agreement or Shares issuable hereunder 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 Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2). For purposes of this 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.

Notwithstanding any contrary provision of this Agreement, no Shares shall be distributed to you unless and until you have made satisfactory arrangements with respect to the payment of income, employment and any other taxes which must be withheld with respect to such Shares. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, may permit you to satisfy such tax withholding obligation, in whole or in part by one or more of the following: (a) paying cash, (b) electing to have the Company withhold otherwise deliverable Shares having a value equal to the minimum amount statutorily required to be withheld (or such greater amount as you may elect if permitted by the Administrator, if such greater amount would not result in adverse financial accounting consequences to the Company as determined by the Company in its discretion), (c) delivering to the Company already vested and owned Shares having a value equal to the amount required to be withheld, or (d) selling a sufficient number of such Shares otherwise deliverable to you through such means as the Administrator may determine in its sole discretion (whether through a broker or otherwise) equal to the amount required to be withheld. If you fail to make satisfactory arrangements for the payment of any required tax withholding obligations with respect to Shares that are vesting, the Administrator, in its sole discretion, may require you to permanently forfeit such Shares and the Shares will be returned to the Plan at no cost.

Any notice to be given to the Company under the terms of this Agreement will be addressed to the Company at 2625 Augustine Drive, Suite 150, Santa Clara, CA, 95054, Attn: Stock Administration, or at such other address as the Company may hereafter designate in writing or electronically.

Except to the limited extent provided in paragraph, this grant and the rights and privileges conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and will not be subject to sale under execution, attachment or similar process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this grant, or any right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process, this grant and the rights and privileges conferred hereby immediately will become null and void. You may, however, dispose of this Award in your will or through a beneficiary designation.

If at any time the Company will determine, in its discretion, that the listing, registration or qualification of the Shares upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of Shares to you (or your estate), such issuance will not occur unless and until such listing, registration, qualification, consent or approval will have been 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 or federal law or securities exchange and to obtain any such consent or approval of any such governmental authority.

The text of the Plan is incorporated in this Agreement by reference. This Agreement and the Notice of Grant are subject to all terms and provisions of the Plan. In the event of a conflict between one or more provisions of this Agreement or the Notice of Grant and one or more provisions of the Plan, the provisions of the Plan will govern.

This Agreement, the Notice of Grant, any duly authorized written agreement between you and the Company and the Plan constitute the entire understanding between you and the Company regarding this Award. Any prior agreements, commitments or negotiations concerning this Award are superseded. This Agreement may be amended only by another written agreement between the parties. Notwithstanding anything to the contrary in the Plan or this Agreement, the Company reserves the right to revise this Agreement as it deems necessary or advisable, in its sole discretion and without your consent, to comply with Section 409A or to otherwise avoid imposition of any additional tax or income recognition under Section 409A in connection to this grant of RSUs.
