 8. Termination of Employment. For all purposes of this Grant Agreement, Grantee shall be
considered to have terminated employment with the Company when Grantee incurs a “separation from service” with the Company within the meaning of Section 409A(a)(2)(A)(i) of the Code and applicable administrative guidance issued
thereunder. If any payment under this Grant Agreement would be subject to additional taxes under Section 409A of the Code because the timing of such payment is not delayed as provided in Section 409A(a)(2)(B) of the Code, then such payment

withhold from any grant of Units made pursuant to this Grant Agreement or from any compensation or other amount owing to Grantee the amount (in cash, Units, other securities or other property) of any applicable taxes payable at the minimum statutory
rate in respect of this Grant Agreement, the vesting or any payment or transfer under the Grant Agreement and to take such other action as may be necessary in the opinion of the Company to satisfy its withholding obligations for the payment of such
taxes, and in this regard, such withholding obligation may be satisfied by Grantee timely remitting (in cash, check or wire transfer) to the Company or the Internal Revenue Service, at the Company’s election, the amount of any such applicable
taxes (as determined by the Company). 
 (b) Net Units. Unless Grantee satisfies the tax withholding obligation set forth
above by timely remitting such amounts to the Company or the Internal Revenue Service (at the Company’s election) by cash, check or wire transfer, all Units to be issued pursuant to this Grant Agreement shall be net of tax withholding, such
that the tax withholding obligation of Grantee in respect of this Grant Agreement and such Units is satisfied through the retention by the Company of a number of Units equal to Grantee’s aggregate tax withholding obligation divided by the
per-unit Fair Market Value for the date immediately prior to the date of such issuance of Units.

descent and distribution and shall not be subject to execution, attachment or similar process. Upon any attempt by Grantee to transfer, assign, pledge, hypothecate or otherwise dispose of such rights contrary to the provisions in this Grant
Agreement or the Plan, or upon the levy of any attachment or similar process upon such rights, such rights shall immediately become null and void. 
 11. Binding Effect. This Grant Agreement shall be binding upon and inure to the benefit of any successor or successors of the Company and upon any person lawfully claiming under Grantee.
