Item 3.
Source and Amount of Funds or Other Consideration

The information previously provided in response to Item 3 is hereby amended and supplemented by adding to the end of Item 3 the following:

“On August 13, 2018, and November 12, 2018 SHB received an additional 332,220 and 338,034 respectively, Class B PIK Units as distributions on the Class B Convertible Units.”

Item 5.
Interest in Securities of the Issuer

Item 5 of the Original Schedule 13D is hereby amended and restated in its entirety as follows:

“(a) and (b) As of November 12, 2018, 48,686,215 Common Units, 19,652,831 Class B Convertible Units and 12,213,713 Subordinated Units are outstanding.  The Class B Convertible Units convert into Common Units at the Class B Conversion Rate on the Class B Conversion Date; the initial Class B Conversion Rate is 1.0 (i.e., one Common Unit for each Class B Convertible Unit). The Subordinated Units convert into Common Units on a one-for-one basis on the expiration of the Subordination Period. Because such Class B Convertible Units and Subordinated Units were acquired in connection with transactions having the purpose or effect of changing or influencing the control of SXE, such Class B Convertible Units and Subordinated Units are considered converted for purposes of the calculations of the amounts noted under Rule 13d-3(d)(1)(i) of the Securities Exchange Act of 1934, as amended. As a result of the relationship of the Filing Parties to SHB, each of the Filing Parties is deemed to be the beneficial owner, with shared power to vote or direct the vote and shared power to dispose or direct the disposition, of 58,358,618 Common Units, which constitutes approximately 72.4% of the outstanding Common Units (giving effect to the conversion of all outstanding Class B Convertible Units and Subordinated Units).
