WHEREAS, it has been determined under the Plan that it would be in the best interests of the Company to grant the Restricted Stock
Units provided herein to the Participant. 
 NOW, THEREFORE, in consideration of the mutual covenants and promises hereinafter set
forth and for other good and valuable consideration, the parties hereto hereby mutually covenant and agree as follows: 
 1.
Incorporation By Reference; Plan Document Receipt. This Agreement is subject in all respects to the terms and provisions of the Plan (including, without limitation, any amendments thereto adopted at any time and from time to time
unless such amendments are expressly intended not to apply to the Award provided hereunder), all of which terms and provisions are made a part of and incorporated in this Agreement as if they were each expressly set forth herein. Any capitalized
term not defined in this Agreement shall have the same meaning as is ascribed thereto in the Plan. The Participant hereby acknowledges receipt of a true copy of the Plan and that the Participant has read the Plan carefully and fully understands its
content. In the event of any conflict between the terms of this Agreement and the terms of the Plan, the terms of the Plan shall control. 

2. Grant of Restricted Stock Units Award. The Company hereby grants to the Participant, as of the Grant Date specified above,
the number of Restricted Stock Units specified above. Except as otherwise specifically provided for in the Plan or this Agreement, no adjustments shall be made for dividends in cash or other property, distributions or other rights in respect of
Restricted Stock Units issued pursuant to this Agreement. The Participant shall not have the rights of a stockholder in respect of the shares underlying this Award until such shares are delivered to the Participant in accordance with Section 4
hereof. 







 3. Vesting. 

(a) Subject to the provisions of Sections 3(b) through 3(d) hereof, the Restricted Stock Units subject to this grant shall become vested on the
first anniversary of the Grant Date, provided that the Participant has not incurred a Termination prior to such vesting date. There shall be no proportionate or partial vesting in the periods prior to each vesting date and all vesting shall occur
only on the appropriate vesting date, subject to the Participant’s continued service with the Company or any of its Affiliates or Subsidiaries on each applicable vesting date. 

(b) Committee Discretion to Accelerate Vesting. Notwithstanding the foregoing, the Committee may, in its sole discretion, provide for
accelerated vesting of the Restricted Stock Units at any time and for any reason. 
 (c) Change in Control. The Restricted Stock
Units shall become fully vested upon the occurrence of a Change in Control so long as the Participant has not incurred a Termination prior to such Change in Control. 

(d) Forfeiture. Subject to the Committee’s discretion to accelerate vesting hereunder and subject to the provisions of Sections
3(b) and 3(c) above, all unvested Restricted Stock Units shall be immediately forfeited upon the Participant’s Termination for any reason. 

4. Delivery of Shares. Within thirty (30) days following the vesting of the Restricted Stock Units, the Participant shall
receive the number of shares of Common Stock that correspond to the number of Restricted Stock Units that have become vested on the applicable vesting date; provided that the Participant shall be obligated to pay to the Company the aggregate
par value of the shares of Common Stock to be issued within ten (10) days following the issuance of such shares unless such shares have been issued by the Company from the Company’s treasury. 

5. Dividends; Rights as Stockholder. Except as otherwise provided herein, the Participant shall have no rights as a stockholder
with respect to any shares of Common Stock covered by any Restricted Stock Unit, including without limitation, any right to any dividends or other cash or stock-based distributions, unless and until the Participant has become the holder of record of
such shares. 
 6. Non-Transferability. Other than with respect to estate planning purposes benefitting a spouse or child, the
Restricted Stock Units, and any rights and interests with respect thereto, issued under this Agreement and the Plan shall not, prior to vesting, be sold, exchanged, transferred, assigned or otherwise disposed of in any way by the Participant (or any
beneficiary of the Participant), other than by testamentary disposition by the Participant or the laws of descent and distribution. Any attempt to sell, exchange, transfer, assign, pledge, encumber or otherwise dispose of or hypothecate in any way
any of the Restricted Stock Units, or the levy of any execution, attachment or similar legal process upon the Restricted Stock Units, contrary to the terms and provisions of this Agreement and/or the Plan shall be null and void and without legal
force or effect. 
 7. Legend. The Company may at any time place legends referencing any applicable federal, state or foreign
securities law restrictions on all certificates representing shares of Common Stock issued pursuant to this Agreement. The Participant shall, at the request of the Company, promptly present to the Company any and all certificates representing shares
of Common Stock acquired pursuant to this Agreement in the possession of the Participant in order to carry out the provisions of this Section 7.

to the Company, an amount sufficient to satisfy any federal, state, local and foreign taxes of any kind (including, but not limited to, the Participant’s FICA and SDI obligations) which the Company, in its sole discretion, deems necessary to be
withheld or remitted to comply with the Code and/or any other applicable law, rule or regulation with respect to the Restricted Stock Units and, if the Participant fails to do so, the Company may otherwise refuse to issue or transfer any shares of
Common Stock otherwise required to be issued pursuant to this Agreement. Any minimum statutorily required withholding obligation with regard to the Participant may be satisfied by reducing the amount of cash or shares of Common Stock otherwise
deliverable to the Participant hereunder. 
 10. Securities Representations. This Agreement is being entered into by the
Company in reliance upon the following express representations and warranties of the Participant. The Participant hereby acknowledges, represents and warrants that:

Securities Act, the Exchange Act and in each case any respective rules and regulations promulgated thereunder) and any other law, rule regulation or exchange requirement applicable thereto. The Company shall not be obligated to issue the Restricted
Stock Units or any shares of Common Stock pursuant to this Agreement if any such issuance would violate any such requirements. As a condition to the settlement of the Restricted Stock Units, the Company may require the Participant to satisfy any
