Explanation of Responses:

1. Each phantom unit is the economic equivalent of one common unit.

2. On November 9, 2020, the Issuer effected a 1-for-15 reverse unit split (the "Reverse Unit Split"). Pursuant to the Reverse Unit Split, common unitholders received one common unit for every 15 common units owned at the close of business on November 9, 2020. All fractional units created by the Reverse Unit Split were rounded to the nearest whole unit. The common units began trading on a split-adjusted basis on November 10, 2020. After giving effect to the Reverse Unit Split, the number of issued and outstanding common units decreased to 3,774,992.

3. Common Units being withheld to pay tax liability.

4. These phantom units vested on October 18, 2022, subject to continued employment and accelerated vesting, as provided in the applicable award agreement. The Reporting Person will receive Distribution Equivalent Rights ("DERs") for each phantom unit, providing for payment on the vesting date of a lump sum of cash equal to the accrued distributions from and after the grant date of the phantom units.

5. The phantom units and associated DERs do not expire. The phantom units are settled upon vesting in common units (on a one-for-one basis) or in cash, at the discretion of the Issuer.

6. After giving effect to the transactions reported in this Report, the Reporting Person holds an aggregate 19,566 phantom units.
