9.    Nature of the Grant. In accepting this Award Agreement, the Participant acknowledges that:

(a)    the grant of Restricted Units is voluntary and occasional and does not create any contractual or other right to receive future awards of Restricted Units, or benefits in lieu of Restricted Units even if Restricted Units have been awarded repeatedly in the past; and

(b)    Restricted Units are not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculation of any severance, resignation, termination, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments and in no event should be considered as compensation for, or relating in any way to, past services for the Corporation or its Subsidiaries.

Without the consent of the Participant, this Award Agreement may be amended or supplemented (i) to cure any ambiguity or to correct or supplement any provision herein which may be defective or inconsistent with any other provision herein or (ii) to add to the covenants and agreements of the Corporation for the benefit of the Participant or to add to the rights of the Participant or to surrender any right or power reserved to or conferred upon the Corporation in this Award Agreement; provided, in each case, that such changes or corrections shall not adversely affect the rights of the Participant under this Award Agreement without the Participant’s consent. Additionally, however, notwithstanding the foregoing or anything to the contrary herein, without the consent of the Participant, this Award Agreement may be amended or supplemented to make such changes as the Corporation, upon advice of counsel, (i) determines are necessary or advisable because of the adoption or promulgation of, or change in or of the interpretation of, any law or governmental rule or regulation, including any applicable federal or state securities or tax laws or (ii) determines are necessary or advisable for the Award either not to be subject to or to be compliant with Section 409A.

12.Section 409A. Notwithstanding anything to the contrary herein, with respect to any payment hereunder (whether issuance of shares of Common Stock or in cash) that constitutes deferred compensation within the meaning of Section 409A, the termination of the Participant’s employment (for clarity, excluding death) shall not result in the payment of such amount unless such termination of employment constitutes a Separation from Service. Further, notwithstanding anything to the contrary herein, if the Participant is a Specified Employee, any payment hereunder (whether issuance of shares of Common Stock or in cash) that constitutes deferred compensation within the meaning of Section 409A payable to the Participant as a result of the Participant’s Separation from Service (for clarity, excluding death) which would otherwise be made within six months of his or her Separation from Service shall instead be made no earlier than (i) the first business day that is more than six months following the Participant’s Separation from Service and (ii) the Participant’s death. It is the intention that this Award either not be subject to or be compliant with Section 409A and shall be interpreted accordingly.
