The receipt of the PBRSUs (or some of the units) will be deferred until PBRSUs (or some of the units) can be distributed to the Participant without violating the provisions of Section 162(m). Notwithstanding the foregoing, if a deferral pursuant to the provisions of this section is a violation of Internal Revenue Code (“IRC”) section 409A, the Participant and the Company hereby agree to modify, to the extent possible, the deferral required hereunder such that it is in compliance with IRC section 409A.

12. Dividend and Voting Rights.
