(1) Southcross Holdings Borrower LP ("Borrower") was entitled to receive a payment-in-kind distribution on outstanding Class B Convertible Units pursuant to the Issuer's Third Amended and Restated Agreement of Limited Partnership dated August 4, 2014 (the "Partnership Agreement") no later than February 14, 2016 (the "PIK Distribution"), but the Issuer did not timely make such Class B Convertible Unit distribution on the date due. Nevertheless, the Partnership Agreement provides that the Class B Convertible Unitholders are entitled to have the same rights as if the PIK Distribution had been made. The Class B Convertible Units convert into Common Units at the Class B Conversion Rate (as defined in the Partnership Agreement) on the Class B Conversion Date (as defined in the Partnership Agreement).
(2) The Reporting Persons may be deemed to indirectly beneficially own the Class B Convertible Units owned by Borrower, but each Reporting Person disclaims beneficial ownership except to the extent of its pecuniary interest therein.
(3) Borrower is owned 100% by Southcross Holdings Guarantor LP ("Guarantor"), and its non-economic general partner interest is held by Southcross Holdings Borrower GP LLC, which is owned 100% by Guarantor. Guarantor is owned 100% by Southcross Holdings LP ("Holdings"), and its non-economic general partner interest is held by Southcross Holdings Guarantor GP LLC, which is owned 100% by Holdings. Southcross Energy LLC ("SELLC") owns 29.2% of Holdings and 29.6% of Southcross Holdings GP LLC, the non-economic general partner of Holdings. Further, Charlesbank Capital Partners, LLC is the investment adviser to and the general partner of the general partner of Charlesbank Equity Fund VI, Limited Partnership and its affiliated investment funds, which hold an approximate 85.2% membership interest in SELLC.
