Explanation of Responses:

( 1 )Each phantom unit was the economic equivalent of, and was settled for, one Common Unit representing limited partner interests in the Partnership. ( 2 )The Common Units are held by RER Legacy Investments LLC ("RER LLC"). The Reporting Person is a member of RER LLC and may be deemed the beneficial owner of the Common Units held by RER LLC. ( 3 )The Common Units are held by RER Investments LLC. The Reporting Person is the sole member of RER Investments LLC. ( 4 )The Common Units included in this report were purchased by the Reporting Person's son for his own account in a Directed Unit Program in connection with the initial public offering of common units representing limited partner interests in the Issuer. The Reporting Person disclaims beneficial ownership of these securities, and this report shall not be deemed an admission that the reporting person is the beneficial owner of such securities for the purposes of Section 16 or for any other purpose. ( 5 )The Reporting Person is a participant in the Hi-Crush Partners LP First Amended and Restated Long-Term Incentive Plan and received 49,936 phantom units on September 14, 2016 (the "2016 Performance Award") vesting based on the Partnership's performance compared to the performance of entities in a designated peer group for the three-year period ending December 31, 2018. 96% of the 2016 Performance Award phantom units vested and settled on February 1, 2019 and the remaining 4% of the 2016 Performance Award phantom units expired on that date.
