Subject to the conditions set forth below and in the remainder of this Agreement, the Company hereby grants you, effective as of the Date of Grant, an award consisting of [●] Restricted Stock Units, whereby each Restricted Stock Unit represents the right to receive one share of common stock, par value $0.001 per share, of the Company (“Stock”), plus the additional rights to Dividend Equivalents set forth in Section 3, in accordance with the terms and conditions set forth herein and in the Plan (the “Award”). To the extent that any provision of this Agreement conflicts with the expressly applicable terms of the Plan, you acknowledge and agree that those terms of the Plan shall control and, if necessary, the applicable terms of this Agreement shall be deemed amended so as to carry out the purpose and intent of the Plan. Terms that have their initial letter capitalized, but that are not otherwise defined in this Agreement shall have the meanings given to them in the Plan. 2. No Shareholder Rights. The Restricted Stock Units granted pursuant to this Agreement do not and shall not entitle you to any rights of a holder of Stock prior to the date shares of Stock are issued to you in settlement of the Award. Your rights with respect to the Restricted Stock Units shall remain forfeitable at all times prior to the date on which rights

2 become vested and the restrictions with respect to the Restricted Stock Units lapse in accordance with Section 6. 3. Dividend Equivalents. In the event that the Company declares and pays a dividend in respect of its outstanding shares of Stock and, on the record date for such dividend, you hold Restricted Stock Units granted pursuant to this Agreement that have not been settled, the Company shall create a bookkeeping account that will track the amount of the Dividend Equivalents you would have been entitled to receive on or following the Date of Grant as if you had been the holder of record of the number of shares of Stock related to the Restricted Stock Units that have not been settled as of the record date, calculated without interest. All Dividend Equivalent amounts credited to your bookkeeping account from the Date of Grant until the settlement of the underlying Restricted Stock Units shall be paid to you in a lump sum cash payment on the date that the underlying Restricted Stock Units associated with that Dividend Equivalent amount is settled pursuant to Section 5 below. In the event that the Restricted Stock Units are forfeited to the Company without settlement to you, you will also forfeit any associated Dividend Equivalent amounts. 4. Restrictions; Forfeiture. The Restricted Stock Units are restricted in that they may not be sold, transferred or otherwise alienated or hypothecated until these restrictions are removed or expire as contemplated in Section 6 and Stock is issued to you as described in Section 5. The Restricted Stock Units are also restricted in the sense that they may be forfeited to the Company (the “Forfeiture Restrictions”). 5. Issuance of Stock. No shares of Stock shall be issued to you prior to the date on which the Restricted Stock Units vest and the restrictions, including the Forfeiture Restrictions, with respect to the Restricted Stock Units lapse, in accordance with Section 6. After the Restricted Stock Units vest pursuant to Section 6, the Company shall, promptly and within 60 days of such vesting date, cause to be issued Stock registered in your name in payment of such vested Restricted Stock Units. The Company shall evidence the Stock to be issued in payment of such vested Restricted Stock Units in the manner it deems appropriate. The value of any fractional Restricted Stock Units shall be rounded down at the time Stock is issued to you in connection with the Restricted Stock Units. No fractional shares of Stock, nor the cash value of any fractional shares of Stock, will be issuable or payable to you pursuant to this Agreement. The value of such shares of Stock shall not bear any interest owing to the passage of time. Neither this Section 5 nor any action taken pursuant to or in accordance with this Section 5 shall be construed to create a trust or a funded or secured obligation of any kind. 6. Vesting Schedule. Subject to all other terms and conditions of this Agreement, your Restricted Stock Units will be divided into four (4) tranches and will vest in accordance with the following schedule, provided that you remain a service provider to the Company or its Subsidiaries from the Date of Grant until the applicable vesting date: Percentage of Restricted Stock Units Vesting Date 25% January 1, [●] 25% April 1, [●] 25% July 1, [●] 25% October 1, [●]

If your service relationship with the Company or any of its Subsidiaries terminates for any reason, then those Restricted Stock Units for which the restrictions have not lapsed as of the date of termination shall become null and void and those Restricted Stock Units shall be forfeited to the Company. The Restricted Stock Units for which the restrictions have lapsed as of the date of such termination, including Restricted Stock Units for which the restrictions lapsed in connection with such termination, shall not be forfeited to the Company and shall be settled as set forth in Section 5. 8. Payment of Taxes. As an independent contractor you will be responsible for the payment of any and all taxes that result from the grant, vesting or settlement of this Award. 9. Compliance with Securities Law. Notwithstanding any provision of this Agreement to the contrary, the issuance of Stock will be subject to compliance with all applicable requirements of federal, state, or foreign law with respect to such securities and with the requirements of any stock exchange or market system upon which the Stock may then be listed. No Stock will be issued hereunder if such issuance would constitute a violation of any applicable federal, state, or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, Stock will not be issued hereunder unless (a) a registration statement under the Securities Act is, at the time of issuance, in effect with respect to the shares issued or (b) in the opinion of legal counsel to the Company, the shares issued may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. YOU ARE CAUTIONED THAT ISSUANCE OF STOCK UPON THE VESTING OF RESTRICTED STOCK UNITS GRANTED PURSUANT TO THIS AGREEMENT MAY NOT OCCUR UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares subject to the Award will relieve the Company of any liability in respect of the failure to issue such shares as to which such requisite authority has not been obtained. As a condition to any issuance hereunder, the Company may require you to satisfy any qualifications that may be necessary or appropriate to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect to such compliance as may be requested by the Company. From time to time, the Board and appropriate officers of the Company are authorized to take the actions necessary and appropriate to file required documents with governmental authorities, stock exchanges, and other appropriate Persons to make shares of Stock available for issuance. 10.
