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,

2 690823.0002 EAST 114364264 v1 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.

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 or Section 7, as applicable. After the Restricted Stock Units vest pursuant to Section 6 or 7, as applicable, the Company shall, promptly and within 60 days of such Vesting Date (as defined below), 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. Except as provided otherwise in Section 7, the Restricted Stock Units granted pursuant to this Agreement will vest, provided that you remain in the employ of, or a service provider to, the Company or any of its Subsidiaries through and including each of the applicable dates set forth below in Sections 6(a) and 6(b) (each, a “Vesting Date”):

3 690823.0002 EAST 114364264 v1 (a) Time-Based Restricted Stock Units. Sixty percent (60%) of the total number of Restricted Stock Units subject to the Award shall vest based upon the passage of time (the “Time-Based Restricted Stock Units”) in accordance with the following schedule: Portion of Time-Based Restricted Stock Units to Vest Vesting Dates 1/3 First Anniversary of Date of Grant 1/3 Second Anniversary of Date of Grant 1/3 Third Anniversary of Date of Grant Total: 100% of Time-Based Restricted Stock Units Notwithstanding the foregoing, if the number of shares of Time-Based Restricted Stock is not evenly divisible by three, then no fractional shares shall vest and the installments shall be as equal as possible with the smaller installments vesting first. (a) Performance-Based Restricted Stock Units. The remaining forty percent (40%) of the Restricted Stock Units subject to the Award shall vest based upon the satisfaction of performance criteria (the “Performance-Based Restricted Stock Units”). Fifty percent (50%) of the Performance-Based Restricted Stock Units (the “First Tranche”) shall vest on the day, if any, that the average of the daily volume-weighted average share price of the Company’s Stock on the Nasdaq or such other primary stock exchange on which the Stock is listed and traded over any period of twenty (20) consecutive trading days equals or exceeds $[●] per share (the “First Hurdle”) within the three (3) year period beginning on the Date of Grant (the “Performance Period”). If the First Hurdle is not attained during the Performance Period, the Restricted Stock Units subject to the First Tranche shall become null and void and those Restricted Stock Units shall be forfeited to the Company without any payment to you. The remaining fifty percent (50%) of the Performance-Based Restricted Stock Units (the “Second Tranche”) shall vest on the day, if any, that the average of the daily volume-weighted average share price of the Company’s Stock on the Nasdaq or such other primary stock exchange on which the Stock is listed and traded over any period of twenty (20) consecutive trading days equals or exceeds $[●] per share (the “Second Hurdle”) within the Performance Period. If the Second Hurdle is not attained during the Performance Period, the Restricted Stock Units subject to the Second Tranche shall become null and void and those Restricted Stock Units shall be forfeited to the Company without any payment to you. Notwithstanding the foregoing, if an installment of the vesting of any Performance-Based Restricted Stock Units would result in a fractional Restricted Stock Unit becoming vested, that installment will be rounded to the next higher or lower share, as determined by the Committee, except for the second installment, if any, which will be for the balance of the Award. 7. Termination of Services and Change in Control. (a) Termination Generally. Subject to Section 7(b), Section 7(c), or Section 7(d), as applicable, if your service relationship with the Company or any of its Subsidiaries terminates for any reason, then those Restricted Stock Units (both Time-Based Restricted Stock

4 690823.0002 EAST 114364264 v1 Units and Performance-Based Restricted Stock Units) which have not vested and 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 without any payment to you. The Restricted Stock Units which have not vested and for which the restrictions have lapsed as of the date of such termination shall not be forfeited to the Company and shall be settled as set forth in Section 5. For purposes of clarity, if your service relationship is transferred between the Company and/or any of its Subsidiaries, such a transfer shall not constitute a termination of the service relationship. (b) Death. In the event that your service relationship with the Company or any of its Subsidiaries terminates due to your death, all Time-Based Restricted Stock Units that have not already become vested pursuant to Section 6(a) of this Agreement shall immediately become vested. For purposes of clarity, the termination of your service relationship due to your death will not automatically vest your Performance-Based Restricted Stock Units. (c) Change in Control. In the event of a Change in Control, all Restricted Stock Units that have not already become vested pursuant to Section 6 of this Agreement and have not previously been forfeited shall immediately become vested. (d) Effect of Individual Agreement. Notwithstanding any provision herein to the contrary, in the event of any inconsistency between Section 6 or Section 7 and any individual employment, severance, change in control or other similar agreement entered into by and between you and the Company, the terms of such other agreement shall control. 8. Leave of Absence. With respect to the Award, the Company may, in its sole discretion, determine that if you are on leave of absence for any reason you will be considered to still be in the employ of, or providing services for, the Company, provided that rights to the Restricted Stock Units during a leave of absence will be limited to the extent to which those rights were earned or vested when the leave of absence began. 9. Payment of Taxes. The Company may require you to pay to the Company (or the Company’s Subsidiary if you are an employee of a Subsidiary of the Company), an amount the Company deems necessary to satisfy its (or its Subsidiary’s) current or future obligation to withhold federal, state, provincial or local income or other taxes that you incur as a result of the Award. With respect to any required tax withholding, you may (a) direct the Company to withhold from the shares of Stock to be issued to you under this Agreement the number of shares necessary to satisfy the Company’s obligation to withhold taxes; which determination will be based on the shares’ Fair Market Value on the applicable Vesting Date; (b) deliver to the Company shares of Stock sufficient to satisfy the Company’s tax withholding obligations, based on the shares’ Fair Market Value on the applicable Vesting Date; (c) deliver cash to the Company sufficient to satisfy its tax withholding obligations; or (d) satisfy such tax withholding through any combination of clauses (a), (b) and/or (c). If you desire to elect to use the stock withholding option described in subparagraph (a), you must make the election at the time and in the manner the Company prescribes. The Company, in its discretion, may deny your request to satisfy its tax withholding obligations using a method described under clause (a) or (b). In the event the Company determines that the aggregate Fair Market Value of the shares of Stock withheld as payment of any tax withholding obligation is insufficient to discharge that tax

5 690823.0002 EAST 114364264 v1 withholding obligation, then you must pay to the Company, in cash, the amount of that deficiency immediately upon the Company’s request. 10. 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. 11. Legends. The Company may at any time place legends referencing any restrictions imposed on the shares pursuant to Section 4 or Section 10 of this Agreement on all certificates representing shares issued with respect to this Award. 12. Right of the Company and Subsidiaries to Terminate Services. Nothing in this Agreement confers upon you the right to continue in the employ of or performing services for the Company or any of its Subsidiaries, or interfere in any way with the rights of the Company or any of its Subsidiaries to terminate your employment or service relationship at any time. 13. Furnish Information. You agree to furnish to the Company all information requested by the Company to enable it to comply with any reporting or other requirements imposed upon the Company by or under any applicable statute or regulation. 14.
