All phantom units will be settled in cash, but the timing of the cash payment of the First Tranche was determined by a payment election the Reporting Person was required to make 30-days after the grant date. Pursuant to the terms of the grant agreement, the Reporting Person elected to defer the payment of the vested First Tranche until the payment associated with the Second Tranche, except for amounts accelerated and withheld to satisfy applicable tax withholding obligations related to the December 1, 2016 vesting event. The Second Tranche is not subject to a deferral election and will be paid to the Reporting Person within 30 days of the vesting event.

All phantom units will be settled in cash, but the timing of the cash payment of the First Tranche was determined by a payment election the Reporting Person was required to make 30-days after the grant date. Pursuant to the terms of the grant agreement, the Reporting Person elected to have the phantom common units associated with the First Tranche paid within 30 days of vesting of the First Tranche. The Second Tranche is not subject to a deferral election and will be paid to the Reporting Person within 30 days of the vesting event.
