The Grant Agreements for your Executive Performance Plan Unit Grants for the

sentence:
“In the event that you incur a Severance (as defined in the 2013 Performance
Plan) before or during a Performance Period, the Units with respect to any such
Performance Period shall be deemed to have been fully earned at the target
amount of the award opportunity specified on the grant summary page, and in the
event that you incur a Severance on or prior to the Vesting Date but after
completion of a Performance Period, the Units with respect to any such completed
Performance Period shall be deemed to have been fully earned in the amount
determined by the Compensation Committee following the end of the Performance
Period, and in each case shall be paid within 30 days after your Severance.”
