Explanation of Responses:
1. US Development Group, LLC ("USD") is the parent company of USD Group LLC ("USD Group") which is the sole owner of the membership interests of USD Partners GP LLC, the Issuer's general partner (the "General Partner"). USD manages USD Group. ECP Control Co, LLC ("ECP Control Co") is the managing member of Energy Capital Partners III, LLC ("ECP"), which is the direct or indirect general partner of each of Energy Capital Partners III-A, LP ("ECP-A"), Energy Capital Partners III-B (USD IP), LP ("ECP-B"), and Energy Capital Partners III-C (USD IP), LP ("ECP-C") and together with ECP-A and ECP-B, the "ECP Funds"). ECP is the direct or indirect general partner of each of the ECP Funds and has voting and investment control over the securities owned by the ECP Funds. USD Holdings, LLC ("USD Holdings") and the ECP Funds are members of USD and, with ECP and ECP ControlCo, may be deemed to indirectly beneficially own the limited partnership interests beneficially owned by USD.
2. USD Group directly holds 5,278,963 common units and 6,278,127 subordinated units representing 32.2% of the common units and 100% of the subordinated units for a combined 50.8% of the limited partnership interests in the Issuer. USD Holdings is a 45.5% member of USD, and may therefore be deemed to indirectly beneficially own 2,401,928 common units and 2,856,548 subordinated units, representing 45.5% of the limited partnership interests held by USD Group. ECP ControlCo, ECP and the ECP Funds collectively hold 49.2% of the membership interest in USD, and may therefore be deemed to indirectly beneficially own 2,597,250 common units and 3,088,838 subordinated units, representing 49.2% of the limited partnership interests held by USD Group.
3. The subordinated units will convert into common units on a one-for-one basis in separate sequential tranches. Each tranche will be comprised of 20.0% of the subordinated units outstanding as of October 15, 2014. A separate tranche will convert on each business day occurring on or after October 1, 2015 (but no more than once in any twelve-month period) subject to certain conditions being met.
