[1] General and administrative expenses include costs allocated to the Tyler Predecessor and the El Dorado Predecessor for general and administrative support provided to the Tyler Predecessor by Delek Refining and to the El Dorado Predecessor by Lion Oil, including services such as corporate management, risk management, accounting and human resources. The costs that were allocated to us by Delek Refining were $0.5 million and $0.8 million for the years ended December 31, 2013 and 2012, respectively. The costs that were allocated to us by Lion Oil were $0.1 million
[2] Excludes volumes gathered on the SALA Gathering System
[3] Volumes gathered on the SALA Gathering System will not be subject to an additional fee for transportation on our Lion Pipeline System to the El Dorado Refinery
[4] Maximum term gives effect to the extension of the commercial agreement pursuant to the terms thereof.
[5] For any volumes in excess of 50,000 bpd, the throughput fee will be $0.652/bbl.
[6] Following the primary term, the marketing agreement automatically renews for successive one-year terms unless either party provides notice of non-renewal 10 months prior to the expiration of the then-current term. An additional fee of 50% of the margin on products sold is also paid pursuant to the agreement. The fee shall not be less than $175,000 nor greater than $500,000 per quarter.
[7] On July 19, 2013, we acquired the Hopewell Pipeline in order to effectively connect it with the Big Sandy Pipeline and thereby return the Big Sandy Terminal to operation. In connection with the acquisition, on July 25, 2013, we and Delek entered into the Amended and Restated Services Agreement (Big Sandy Terminal and Pipeline), which amended and restated the terminalling services agreement for the Big Sandy Terminal originally entered into in connection with the Offering.
[8] Pursuant to the agreement, capital projects are to be completed in two phases in order to support and enhance blending activities at the terminal. Upon completion of phase II capital projects, the minimum throughput fees will decrease and storage fees will increase.
